FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with dysphagia is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about dysphagia, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to dysphagia, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on dysphagia. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to dysphagia, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on dysphagia. The Editors

CHAPTER 1. STUDIES ON DYSPHAGIA Overview In this chapter, we will show you how to locate peer-reviewed references and studies on dysphagia.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and dysphagia, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “dysphagia” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
When It's Hard to Swallow: What to Look for in Patients With Dysphagia Source: Postgraduate Medicine. 105(7): 131-134, 141-142, 145. June 1999. Summary: A wide variety of causes, from an obstructive foreign body to a cerebrovascular accident (stroke) can disrupt the complicated processes that make up a swallow. In this article, the third in a series of three on esophageal diseases, the authors describe the many symptoms and other factors (e.g., onset, progression, exacerbating conditions) that can provide clues to the cause of dysphagia. The authors also discuss useful diagnostic studies and how to choose among them on the basis of findings during history taking. Dysphagia is classified as oropharyngeal (also called transfer dysphagia) or esophageal. The most common cause of oropharyngeal dysphagia is cerebrovascular accidents (stroke); other causes include oropharyngeal structural lesions, systemic and local muscular disease, and diverse neurologic disorders. Esophageal dysphagia may

Summary: As the scope of practice in the field of speech language pathology has expanded to include dysphagia (swallowing disorders), the school based clinician's recognition of students with potential swallowing problems has increased. Dysphagia is common in children with severe cerebral palsy and multiple disabilities; it can also occur in at-risk neonates and children with a variety of neurological deficits and structural abnormalities. This article describes the development of a school based dysphagia team within the St. Tammany Parish school system located in Covington, Louisiana. The team's vision was to ensure safe nutrition and hydration for students at risk for swallowing dysfunction during school hours. The authors discuss how the team was initially formed, the process of identifying students who were exhibiting a swallowing disorder, steps taken for staff development, and problems encountered in seeking administrative approval. The authors also present a brief discussion of the current status of the dysphagia program, along with future plans for further implementation. Numerous appendices offer recordkeeping and other forms used by the program. 1 figure. 1 table. 7 references.

Esophageal Dysphagia: Is the Cause Benign or Potentially Deadly? A Guide to Key Components of the Work-Up Source: Journal of Critical Illness. 13(4): 236-242, 245-246. April 1998. Contact: Available from Cliggott Publishing Company. 55 Holly Hill Lane, Greenwich, CT 06831-0010. (203) 661-0600. Summary: Dysphagia (difficulty in swallowing) is an important symptom that nearly always signals an organic abnormality. In this article, the authors review the causes of dysphagia and the approach to diagnosis. They focus on the most common esophageal causes of dysphagia and describe available diagnostic methods and management options. They present a diagnostic algorithm to help readers identify the underlying cause of dysphagia. The authors note that clues in the patient history often point to the cause. For example, worsening dysphagia and weight loss in a patient older than 50 may indicate esophageal carcinoma, while chest pain associated with intermittent dysphagia suggests diffuse esophageal spasm. If dysphagia occurs with both solids and liquids or with liquids alone, a motility disorder (such as achalasia), scleroderma, or a spastic motor disorder may be involved. Achalasia is often characterized by bland regurgitation of ingested food and thick saliva; weight loss may be striking. Other, less common causes of dysphagia include esophageal diverticula, foreign bodies, vascular or mediastinal abnormalities, and cervical osteoarthritis. A barium swallow with a solid bolus challenge is the initial test for all patients who have dysphagia. Esophageal manometry or esophagogastroscopy may be required for definitive diagnosis. 6 figures. 2 tables. 15 references. (AA-M).

Contact: Available from American Academy of Family Physicians. 11400 Tomahawk Creek Parkway, Leawood, KS 66211-2672. (800) 274-2237. Website: www.aafp.org. Summary: Dysphagia (difficulty swallowing) is a problem that commonly affects patients cared for by family physicians in the office setting, as hospital inpatients and as nursing home residents. This article reviews the diagnostic strategies that should be used to evaluate these patients. Familiar medical problems, including cerebrovascular accidents (stroke), gastroesophageal reflux disease, and medication related side effects, often lead to complaints of dysphagia. Stroke patients are at particular risk of aspiration because of dysphagia. Classifying dysphagia as oropharyngeal, esophageal and obstructive, or neuromuscular symptom complexes lead to a successful diagnosis in 80 to 85 percent of patients. Based on the patient history and physical examination barium esophagram or gastroesophageal endoscopy can confirm the diagnosis. Special studies and consultation with subspecialists can confirm difficult diagnoses and help guide treatment strategies. 3 figures. 4 tables. 19 references.

Contact: Available from American Society for Parenteral and Enteral Nutrition. 8630 Fenton Street, Suite 412, Silver Spring, MD 20910-3805. (301) 587-6315. Summary: Dysphagia (swallowing difficulty) is a common symptom that uncommonly has no underlying cause. Many diseases and disorders can produce dysphagia, varying from neurologic causes such as cerebrovascular accident (CVA) or Parkinson's disease to infectious causes such as candidiasis. This article on the radiologic evaluation of the patient with dysphagia, is from a medical nutrition and device roundtable on dysphagia. The author stresses that the radiographic evaluation of the patient with dysphagia should be tailored to each individual depending on symptoms and the site of symptoms. The author discusses variations in technique and an approach to the interpretation of the study. Swallowing physiology is analyzed by considering a series of the following consecutive stages: oral transfer phase, tongue to soft palate seal, soft palate to superior constrictor seal, bolus propulsion, laryngeal complex, and cricopharyngeal (CP) opening. 22 references.

Contact: Available from American Society for Parenteral and Enteral Nutrition. 8630 Fenton Street, Suite 412, Silver Spring, MD 20910-3805. (301) 587-6315. Summary: Dysphagia has been recognized as a variable that increases hospital length of stay and influences patient outcome. Additionally, in young children, it can seriously affect physical and intellectual development. This article on populations at risk and methods of diagnosis of dysphagia (swallowing difficulty), is from a medical nutrition and device roundtable on dysphagia. Issues regarding the safety of swallowing relate to both airway protection and adequate nutritional intake. The author notes that the likelihood of a dysphagic patient regaining the ability to return to oral intake is improved if the underlying variables resulting in the dysphagia are adequately diagnosed and if the patient is able to participate in a program of swallowing

rehabilitation. Diagnosis of the pathophysiological or anatomical variations that result in swallowing dysfunction generally requires examination beyond that which can be performed with the clinical examination. The author discusses the clinical indicators of dysphagia, frequent etiologies for disordered deglutition (swallowing), and various methods for assessment. 5 tables. 87 references. •
Medications and Dysphagia: How Do They Impact Each Other? Source: Nutrition and Clinical Practice. 14(5 Supplement): S27-S30. October 1999. Contact: Available from American Society for Parenteral and Enteral Nutrition. 8630 Fenton Street, Suite 412, Silver Spring, MD 20910-3805. (301) 587-6315. Summary: Dysphagia is a clinical syndrome that describes the problems or inability to swallow a wet or dry bolus properly and is associated with an impairment in the transportation of the bolus. This article considers how medications can affect any of the three main phases of swallowing: oral, pharyngeal, and esophageal. Medications may cause side effects, such as dry mouth or cognitive impairment, that have a physiologic effect that causes or worsens dysphagia or induces esophagitis. The author emphasizes that understanding the pathophysiology of dysphagia as well as the pharmacology of the medications will heighten the clinicians' awareness to this often misunderstood syndrome. Specific syndromes discussed include transfer dysphagia, cognitive impairment, xerostomia, tardive dyskinesia, neuroleptic malignant syndrome, Parkinson's disease, thyroid disorders, achalasia, esophageal chest pains, gastroesophageal reflux disease (GERD), alcohol use, odynophagia (painful swallowing), and impaired nutritional status associated with dysphagia. The author concludes by recommending a comprehensive medication history of both over the counter and prescription medications that should be done with every patient to rule out medications as a cause of dysphagia. 4 tables. 14 references.

Textural Property Considerations of Food for Dysphagia Source: Nutrition and Clinical Practice. 14(5 Supplement): S57-S59. October 1999. Contact: Available from American Society for Parenteral and Enteral Nutrition. 8630 Fenton Street, Suite 412, Silver Spring, MD 20910-3805. (301) 587-6315. Summary: Food and liquid textures play very important roles in the care of people with dysphagia (swallowing difficulty). This article reviews the textural property considerations of food for dysphagia. The author notes that a major source of frustration for those involved with the patient is how to determine, describe, and deliver the proper textures of foods and liquids. The science of food rheology (a study of the flow and formation of matter) offers the potential to establish standardized food textures using objective measurement techniques. The author discusses the basic physical forces of chewing and swallowing, standard food texture terminology, textures of interest in dysphagia, selection of physical measurement methods and instruments, and techniques to determine the boundaries between the levels of the dysphagia diet. 2 figures. 14 references.

Role of the School-Based Speech-Language Pathologist Serving Preschool Children with Dysphagia: A Personal Perspective Source: Language, Speech, and Hearing Services in Schools. 31(1): 42-49. January 2000. Contact: Available from American Speech-Language-Hearing Association (ASHA). Product Sales, 10801 Rockville Pike, Rockville, MD 20852. (888) 498-6699. TTY (301) 8970157. Website: www.asha.org. Summary: Increasing numbers of children with complex medical conditions are being referred to preschool programs managed by the public school system. And although school based speech language pathologists are often expected or required to work with children exhibiting dysphagia (swallowing disorders), they often lack the necessary resources, equipment, or training. This article presents the background for the service delivery model that is used by the speech language pathologists who work with preschoolers with dysphagia in the Montgomery County, Maryland public school system. The author addresses the controversy about whether this more traditional medical intervention belongs in the educational model. In the educational setting, information and techniques must be accurately and safely transmitted to the entire team working with the child. Ongoing communication between the medical community and the school staff is crucial. The increased responsibility of the speech language pathologist brings with it a variety of concerns, including safety, mandatory cardiopulmonary resuscitation (CPR) training, awareness of dangerous mealtime practices, specific education in pediatric dysphagia intervention, liability, and financial support. 8 references.

Dysphagia
The author presents the various types of swallowing therapy available, including postural changes, sensory enhancements, changes in feeding processes, and exercise programs. Other therapy issues discussed include the relationship of the feeding process to swallowing therapy, the management of drooling, the schedule of therapy, and maintenance programs as compared to therapy. The author concludes that there are many issues involved in determining the nature of treatment to be delivered to a child with dysphagia. However, if the speech language pathologist obtains information from a careful and detailed (usually instrumental) assessment of the child's oropharyngeal swallowing, as well as other aspects of the child's functioning, treatment for swallow disorders in the public schools can be safe and efficient. The article concludes with a list of references for additional reading on therapy procedures. 45 references. •
Dysphagia Caused by Neurologic Deficits Source: Otolaryngologic Clinics of North America. 31(3): 507-524. June 1998. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 32887-4800. Summary: Normal swallowing is a complex, dynamic neuromuscular activity that depends on a set of physiologic behaviors resulting in liquid and solid material moving efficiently and safely from the mouth to the stomach. Problems with swallowing in the oropharynx (oropharyngeal dysphagia) are often linked to neurologic or muscular diseases. This article reviews the neurologic lesions and conditions that account for the majority of oropharyngeal dysphagia cases. The authors first review the physiology and neurophysiology of both normal and abnormal swallowing, then outline the recommended patient physical examination and laboratory work up. Each neurological disease that may contribute to oropharyngeal dysphagia is then discussed: amyotrophic lateral sclerosis, Parkinson's disease, Huntington's disease, multiple sclerosis, myasthenia gravis, stroke (cerebrovascular accident), and laryngeal nerve injury. Dysphagia secondary to acute neurologic deficits, along with other abnormalities, tends to improve with time. Dysphagia resulting from chronic neurologic conditions, however, often worsens as the disease process evolves. 4 tables. 62 references.

Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 32887-4800. Summary: Optimal management strategies are critical for infants and children with feeding and swallowing problems (pediatric dysphagia). This article outlines management decisions for this population. The author stresses that management decisions are best made through a team approach in which caregivers participate with medical and educational professionals to work toward maximizing each child's nutritional status in the context of safe and efficient feeding. Management decisions may incorporate nutrition recommendations, medical and surgical decisions, position guidelines, oral motor and swallow practice, and behavioral intervention. Goals are determined in light of health issues, with adequate nutrition as the most important goal for long term growth. The author discusses management strategies including: food rules applicable to all children beyond infancy, position and posture changes, alterations in various attributes of food and liquid, oral motor and swallow function, utensil changes, adjustments in feeding schedule and pacing, and behavioral intervention with failure to thrive in the context of global issues for children who are oral and non oral feeders.

Evaluation and Management of Postfundoplication Dysphagia Source: American Journal of Gastroenterology. 91(11): 2318-2322. November 1996. Summary: Persistent dysphagia occurs in 3 to 24 percent of patients after fundoplication. This article describes the evaluation and management of postfundoplication dysphagia. There are virtually no data on the success or safety of endoscopic dilation to relieve postfundoplication dysphagia. The authors report on their experience with the endoscopic management of these patients. Thirty-five patients (mean age 49 years; 12 males, 23 females) with dysphagia after fundoplication were referred for endoscopic dilation. Twenty-nine patients had undergone one fundoplication (group A) and six patients had undergone two or more operations (group B). The integrity of the fundoplication was evaluated by barium esophogram and upper endoscopy. In group A, no complications, such as disruption of the fundoplication, resulted from endoscopic dilation, and no one developed new reflux symptoms. Dysphagia resolved in 15 of these 29 patients (52 percent) after dilation. The most important prognostic feature was endoscopic or radiological evidence of a slipped fundoplication. Dilation was successful in relieving dysphagia in only 3 of 11 (27 percent) patients with a slipped fundoplication, compared with 12 of 18 (67 percent) patients with an intact fundoplication. Dysphagia resolved in only one of the six patients in group B. The authors conclude that endoscopic dilation is safe and often effective in patients with postfundoplication dysphagia. However, patients with a slipped fundoplication or who have undergone multiple fundoplications respond poorly to endoscopic dilation. 4 figures. 5 tables. 18 references. (AA-M).

Dysphagia
Summary: Speech dysfunctions (dysphonia) and swallowing dysfunctions (dysphagia) are common following the use of the anterior surgical approach to the cervical spine. Despite functional morbidity and legal implications, the incidence and etiologic factors of these complications have not been adequately established. This article reports on a study in which a questionnaire was mailed to 497 patients who had undergone anterior cervical fusion or anterior cervical discectomy at a university hospital; 150 questionnaires were sent to a control group. The study group response rate was 46 percent; the control group response rate was 51 percent. The incidence of hoarseness in the study group was 51 percent (control group, 19 percent). This difference is statistically significant. Dysphagia was present in 60 percent of the study group patients versus 23 percent of control group patients, also statistically significant. Qualitative questions revealed that constant hoarseness, pain with talking, difficulty eating solid foods, and odynophagia were significantly more common following the anterior approach to the cervical spine. The authors caution that hoarseness and dysphagia may adversely affect recovery and the patient's sense of well being. Preoperative counseling and postoperative evaluation are essential. 1 figure. 4 tables. 10 references. •
Serving Students with Dysphagia in the Schools?: Educational Preparation Is Essential! Source: Language, Speech, and Hearing Services in Schools. 31(1): 76-78. January 2000. Contact: Available from American Speech-Language-Hearing Association (ASHA). Product Sales, 10801 Rockville Pike, Rockville, MD 20852. (888) 498-6699. TTY (301) 8970157. Website: www.asha.org. Summary: Speech language pathologists employed in public schools often serve students with dysphagia (swallowing disorders). This article reviews the delivery of dysphagia interventions to these students. The author emphasizes that students with significant health problems, severe disabilities, or orthopedic impairments may require the services of a school team. This team may be missing a person with adequate training in swallowing evaluation and treatment. The author concludes that speech language pathologists should not provide services to students with dysphagia without pursing continuing education to acquire the necessary knowledge and skills to do so. Providing services without this additional training would compromise the speech language pathologist's ethical standards, jeopardize the student's health, and create undue liability for the school division. 1 table. 6 references.

Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 32887-4800. Summary: The act of swallowing is the most intricate neuromuscular action carried out in the body and because of this complexity, swallowing is affected by many systemic diseases. This article explores the systemic causes of dysphagia (difficulty swallowing) in adults. After recommending that readers first distinguish between oropharyngeal and esophageal dysphagia, the author discusses the etiology (causes) in categories including congenital, traumatic, neoplastic (including cancer), infection, inflammation, degenerative (due to aging), and psychological disorders. In the inflammatory category, the broadest category of diseases that cause dysphagia, the author summarizes the manner in which each of the following diseases may affect swallowing: systemic sclerosis, systemic lupus erythematosus, dermatomyositis, mixed connective tissue

disease, benign mucosal pemphigoid and epidermolysis bullosa, Sjogren's syndrome, rheumatoid arthritis, and secondary autoimmune diseases. It is essential that all patients who present with dysphagia have as thorough a work up as necessary to determine the etiology of their dysfunction. If the cause of a patient's dysphagia is not apparent after a complete head and neck examination, barium swallow, and upper gastrointestinal endoscopy, then a complete physical examination, laboratory testing, and special gastrointestinal tests should be performed to determine if a generalized illness is present. 43 references. •

Summary: The complexity of swallowing has been long appreciated and was described before the development of a sophisticated modality for direct viewing of the swallowing process. This article reviews the history of the discovery of the physiologic principles of swallowing and the development of the evaluation and management of dysphagia. The author describes appropriate diagnostic and treatment tools for various care environments, including acute care hospitals, subacute facilities, rehabilitation hospitals, ambulatory clinics, and home care. Differences in the delivery of dysphagia services in each setting are discussed. The author challenges dysphagia clinicians to provide care on the basis of patient need rather than reimbursement structure. 1 table. 45 references.

Anatomy and Physiology of Pediatric Swallowing Disorders Source: Otolaryngologic Clinics of North America. 31(3): 397-404. June 1998. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 32887-4800. Summary: The functions of the mouth, pharynx, and esophagus are related primarily to the digestive system and represent the most complex neuromuscular unit in the body. The interface between the digestive system, the respiratory system, and the speech producing mechanism further complicates the physiologic of this region, which is under both voluntary and involuntary (reflex) control. This article outlines the relationships between these structures and the functional anatomic units that are derived from them. The authors also present the physiologic changes that accompany maturation from the newborn period through infancy and childhood. The authors separate their discussion into dysphagia (difficulty with swallowing) and the healthy swallowing process. 2 figures. 14 references.

Summary: The inability to maintain oral nutrition because of oropharyngeal dysphagia is common in patients with a variety of neurologic and neuromuscular disorders and severely affects quality of life. This article reports on a study that followed 10 patients

Dysphagia
with oropharyngeal dysphagia and either elevated upper esophageal sphincter (UES) resting pressure, or a high residual pressure or attenuated duration of relaxation on swallowing. The authors note that disorders at the level of the UES can lead to mechanical obstruction to solid foods and incoordination resulting in problems with liquids. Dilation therapy was performed with an 18 to 20 mm Savary dilator, and manometry was repeated after an average period of 4 weeks. A total of 9 out of 10 patients saw their dysphagia improve and have maintained oral nutrition for a mean followup of 13 months. UES residual pressure decreased in 9 out of 10 patients, and the group media value decreased significantly. UES resting pressure decreased in 8 out of 10 patients, and the group median value decreased. Duration of relaxation did not change significantly. Videoradiography was normal in 5 out of 9 responders to therapy. The authors conclude that, for selected patients with oropharyngeal dysphagia and manometric signs of UES dysfunction, dilation therapy may give excellent symptomatic relief, apparently by reducing UES resting pressure or increasing the duration and completeness of relaxation. 3 figures. 3 tables. 17 references.

Website: www.asha.org. Summary: The public schools must follow laws that deal with services for children who meet the legal requirements for having a disability. Children who have swallowing disorders (dysphagia) that require the services of a speech language pathologist typically meet the definition of a child with a disability. This article addresses the importance of the speech language pathologist being aware of legal requirements for the provision of services as well as liability, ethical, and risk management issues related to the provision of such services. The author considers legal aspects as addressed under the Individuals with Disabilities Education Act (IDEA, 1997), Section 504 of the Rehabilitation Act of 1973, and the Family Educational Rights and Privacy Act (FERPA, 1974). Financial considerations relating to service provision are also described; funding of speech language pathologists' services follows the pattern for all special education funding. The author concludes by stressing the importance of all speech language pathologists knowing local school policies regarding such matters as recordkeeping and confidentiality of records. Awareness of funding issues at the local and state level, while important, is less vital than knowing the legal and ethical issues involved in serving children with dysphagia. The speech language pathologist should know what legal resources his or her system has and not be afraid to seek advice. Consideration should also be given to the purchase of liability insurance, because defending oneself in a professional liability action can be expensive. 23 references.

on the role of the dietitian. The author cautions that if dysphagia is undiagnosed or untreated, it can result in progressive malnutrition and its related sequelae. Registered dietitians can play an essential role in early identification of patients at risk for dysphagia and in the development of dysphagia focused nutrition care plans. Dysphagia screening, including mealtime observation, and basic physical examinations can assist in identification and referral to the dysphagia team. The nutrition care plan should be individualized and centered around the primary goal of nutrition therapy for the dysphagic patient, i.e., adequate and safe intake of nutrients. The author concludes that creative and nutritious meal planning as well as continuous monitoring with review of risk factors and diet adjustments are critical to the success of the nutrition plan. 1 figure. 2 tables. 22 references. •

Summary: The stress and complexity of care associated with dysphagia (swallowing disorders), which is a complex disorder managed best by an interdisciplinary team and client family partnership, tend to be underestimated by health providers, family caregivers, and especially third party payment sources. So contend the authors of this article reviewing approaches for managing patients with dysphagia. The authors stress that health providers who use the approaches described in this article may improve outcomes for more clients who have dysphagia and enable them to return home. The authors outline the epidemiologic approach, the ecological approach, a partnership approach, and a holistic approach. The authors consider the sociocultural implications of dysphagia and the many dimensions of the rituals of eating. 15 references.

Contact: Available from American Society for Parenteral and Enteral Nutrition. 8630 Fenton Street, Suite 412, Silver Spring, MD 20910-3805. (301) 587-6315. Summary: There are several types of oropharyngeal dysphagia that are amenable to surgical correction. This article discusses the surgical management of oropharyngeal dysphagia. The author discusses the role of cricopharyngeal myotomy in various forms of dysphagia, the surgical approaches to Zenker's diverticulum, and various surgical options in the management of chronic aspiration. Cricopharyngeal myotomy (CPM) is a procedure designed to decrease the pharyngoesophageal sphincter (PES) pressure by incising the main muscular component of the PES, the cricopharyngeus muscle. PES dysfunction is always seen in patients with Zenker's diverticulum. The author outlines six procedures that can be used for chronic aspiration: tracheotomy, medialization, laryngeal suspension, CPM, laryngeal closure, and laryngotracheal separation or diversion. The author concludes that there is a need for more prospective studies to guide clinicians in the management of dysphagia, both in deciding whether to perform surgery at all and to choose which procedure will have the highest chance of success in helping the individual patient. 6 references.

Summary: This article describes the National Dysphagia Diet project, a program that was conceived by the Dietetics in Physical Medicine and Rehabilitation dietetic practice group in 1996. The group formed a task force, whose goal it was to formulate a new dysphagia diet based on scientific food properties and clinical swallowing problems. Members of the task force include food scientists, clinical and consulting dietitians, speech language pathologists, and food industry representatives, all who have an interest and experience in dysphagia (swallowing disorders). The result of the project is a multilevel dysphagia diet that will be published by the American Dietetic Association in 1999. Another goal of the task force is to standardize all dysphagia diets on a national basis to enhance communication among professionals, institutional food preparers, and food industry leaders to provide better and more consistent care for dysphagic patients. 1 table. 9 references.

Summary: This article describes the use of flexible endoscopic evaluation of swallowing with sensory testing (FEESST), in the diagnosis and management of patients with pharyngeal dysphagia (swallowing difficulty). The authors stress that the comprehensive evaluation of the patient with dysphagia entails a detailed assessment of bolus transport in conjunction with airway protection. As gastroenterologists continue to diagnose and manage patients with dysphagia, an analysis of the hypopharynx as well as the esophagus is necessary; i.e., with FEESST. Unlike the modified barium swallow (MBS), FEESST does not involve x-ray exposure, barium administration, or the presence of a radiologist or a radiology technician. Instead, FEESST involves endoscopy, and gives direct evidence regarding the handling of secretions. Moreover, this technique provides an objective assessment of hypopharyngeal sensitivity which, in turn, gives the clinician information regarding a patient's ability to protect their airway during the

ingestion of food. Like MBS, FEESST requires the participation of a speech language pathologist (SLP), and is extremely useful in guiding the dietary and behavioral management of patients with difficulty swallowing. The authors describe the use of the FEESST technique and provide a basic approach to the management of patients with pharyngeal dysphagia (with the goal of guarding against aspiration and the consequences of aspiration pneumonia). 3 figures. 1 table. 14 references. •

Chronic medical problems and multiple medications can contribute to dysphagia, compromising the patient's nutritional status. The authors stress that the comprehensive management of dysphagia in the home setting includes coordination between the home care team, the hospital's dysphagia team, and the patient and his or her caregiver. Early detection, followed by evaluation, treatment, and education can provide the patient with the best opportunity for a positive outcome.

Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 32887-4800. Summary: This article explores the differential diagnosis of dysphagia in children. Dysphagia is defined as any process that produces difficulty with active transport of food and liquid from mouth to stomach. The authors divide diagnostic pediatric dysphagia into categories including congenital, infectious or inflammatory, systemic, neoplastic, traumatic, and miscellaneous causes. In the first section, the authors discuss choanal atresia (complete nasal obstruction), congenital nasal masses, and cleft lip or cleft palate, laryngomalacia, vocal cord paralysis, laryngeal clefts, tracheoesophageal fistula or esophageal atresia, foregut malformations, and vascular rings. Infectious causes considered include acute pharyngitis, tonsillitis, peritonsillar abscess, retropharyngeal abscess, other deep neck abscesses, epiglottis, and esophagitis. Other causes covered are neurologic causes of dysphagia, central nervous system diseases, diseases of the neuromuscular junction, neoplastic causes of dysphagia (hemangioma, lymphangioma, papilloma, leiomyoma, neurofibroma), oral cavity and posterior pharyngeal injury, surgically related dysphagia, external trauma, caustic ingestion, gastroesophageal reflux, and foreign bodies of the upper aerodigestive tract. The

authors caution that the diagnostic work up can be extremely difficult and exhaustive in many cases. Typical of any diagnostic dilemma, emphasis on history and physical examination remains paramount. Imaging studies can be extremely valuable in certain cases. Once a diagnosis has been established, treatment options are often less problematic. 4 figures. 1 table. 43 references. •

Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 19106-3399. (800) 654-2452 or (407) 345-4000. Summary: This article offers a technical literature review on the management of oropharyngeal dysphagia (swallowing difficulty). The authors describe their selective approach to the literature: outlining a systematic clinical approach to the dysphagic patient and then selecting key illustrative references to either highlight the logic of that approach or substantiate advocated interventions. Editorial emphasis was placed on critical analysis of more current and controversial concepts requiring a broader perspective of the literature. The authors first review oropharyngeal dysphagia and normal oropharyngeal swallowing. They then outline the American Gastroenterological Association (AGA) recommendations stemming from the literature. Clinical assessment of patients with suspected oropharyngeal dysphagia should address five fundamental questions that permit the clinician to establish investigational priorities: does the dysphagia compare with globus sensation or hyposalivation; is the origin of the dysphagia oropharyngeal or esophageal; is there any structural or functional disorder; how severe is the dysphagia and are there any complications; and is there an underlying related or causative disease? The authors review the patient history taking, physical examination, laboratory tests, diagnostic investigations (videofluoroscopic swallowing evaluation, nasoendoscopy, manometry, manofluorography), selection among management options. Management options include surgery and dilation, and swallowing therapy. The authors note the importance of establishing whether or not the patient will be able to sustain adequate nutrition safely via the oral route. The natural history and prognosis of the underlying cause of dysphagia, as well as the patient's cognitive ability, will also influence the choice between oral and nonoral feeding. Introduction of dietary modification and specific swallowing therapy is appropriate at this point. 3 figures. 7 tables. 197 references.

Contact: Available from American Society for Parenteral and Enteral Nutrition. 8630 Fenton Street, Suite 412, Silver Spring, MD 20910-3805. (301) 587-6315. Summary: This article on swallowing and dysphagia (swallowing difficulties) in older adults is from a medical nutrition and device roundtable on dysphagia. In this article, the author considers the role of intervention and prevention. Topics include the incidence of swallowing problems in aging adults; the levels of outcomes assessment in healthy swallowing; swallowing outcomes related to age related disease; and clinical dysphagia related outcomes, including mortality, health status, aspiration pneumonia, nutrition and hydration, and intervention and prevention paradigms. The author concludes that the increasing geriatric population demands practitioners move beyond a 'feel good' perspective about growing old gracefully, to the science of positive aging. Knowledge of specific age related changes permits clinicians and scientists to distinguish healthy old swallowing from dysphagia. It appears the possibility of delaying the onset of dysphagia by proactive exercise regimens for aging adults is the most promising strategy for preserving health and quality of life in this area. 1 figure. 37 references.

Dysphagia
Summary: This article presents the official recommendations of the American Gastroenterological Association (AGA) on the management of oropharyngeal dysphagia (swallowing disorders). The article encourages clinicians to prioritize clinical objectives; each objective is summarized with a brief outline of how to approach each step. These recommendations are developed from a critical review of the medical literature. The recommendations are: ascertain whether oropharyngeal dysphagia is likely and identify the likely etiology (cause); identify structural etiologies of oropharyngeal dysfunction; ascertain the functional integrity of the oropharyngeal swallow (which part of the swallow function is not working); evaluate the risk of aspiration pneumonitis; and determine if the pattern of dysphagia is amenable to therapy. Once structural lesions have been excluded, data supporting surgical intervention are weak. Current strategies of swallowing therapy are modification of diet, swallowing posture, or swallowing technique. The strongest recommendation that can be made pertains to diet modification, with efficacy studies showing reduced risk of airway penetration and of aspiration pneumonia. The article includes a patient care algorithm that summarizes the implementation of these recommendations. 1 figure. 1 reference. •

Customer Service, P.O. Box, CH-4009, Basel, Switzerland. Fax 41 61 306 12 34. Website: www.karger.com. Summary: This article reports on a study of 128 patients with acute, first ever, stroke (cerebrovascular accident). The study was undertaken to determine the prevalence of swallowing disorders, the diagnostic accuracy of the clinical assessment of swallowing function compared with videofluoroscopy, and interobserver agreement for the clinical and videofluoroscopic diagnosis of swallowing disorders and aspiration. The authors found clinical and videofluoroscopic evidence of a swallowing disorder in 51 percent and 64 percent of patients, respectively, and aspiration in 49 percent and 22 percent of patients, respectively. The interobserver agreement between two speech pathologists for the clinical diagnosis of a swallowing disorder and aspiration was food. Between a speech pathologist and radiologist for the videofluoroscopic, diagnosis of a swallowing disorder and aspiration was good' and fair' respectively. Although clinical bedside examination underestimates the frequency of swallowing abnormalities and overestimates the frequency of aspiration compared with videofluoroscopy, bedside examination may still offer valuable information for the diagnosis of swallowing impairment. Long term follow up studies are necessary to determine the use of these types of examinations in predicting the occurrence of important outcome events such as aspiration pneumonia. 2 appendices. 1 figure. 4 tables. 31 references.

Summary: This article reviews developments in dysphagia (swallowing disorders) research of importance to head and neck specialists. The authors emphasize swallowing function after head and neck surgery, in patients with compromised airways, and in association with normal aging. The authors also discuss analysis techniques that permit insights into the effects of specific residual impairments on swallowing physiology, have predictive capabilities, or are of value in directing treatment. Dysphagia is an important risk for aspiration pneumonia, but generally not sufficient to cause pneumonia unless other risk factors are present as well. The authors conclude that advances in dysphagia emulation techniques has led to a closer understanding of normal and abnormal swallowing. 26 references. (AA-M).

Esophageal Dysphagia: Differentiating Benign from Life-Threatening Causes Source: Consultant. 37(10): 2626-2628, 2633, 2636-2640. October 1997. Contact: Available from Cliggott Publishing Company. 55 Holly Hill Lane, Box 4010, Greenwich, CT 06831-0010. Summary: This article reviews the causes of dysphagia (swallowing disorders) and the approach to diagnosis. The authors focus on the most common esophageal causes of dysphagia and describe available diagnostic methods and management options. Worsening dysphagia and weight loss in a patient older than 50 years may indicate esophageal carcinoma, while chest pain associated with intermittent dysphagia suggests diffuse esophageal spasm. Progressive symptoms in a patient with chronic heartburn may be caused by peptic stricture. If dysphagia occurs with both solids and liquids or with liquids alone, a motility disorder, such as achalasia, scleroderma, or a spastic motor

Dysphagia
disorder, may be involved. Achalasia is often characterized by bland regurgitation of ingested food and thick saliva; weight loss may be striking. A barium swallow with a solid bolus challenge is the initial test for all patients who have dysphagia. Esophageal manometry and or esophagogastroscopy may be required for definitive diagnosis. The authors also present an algorithm that demonstrates how clues in the patient's history can help identify the underlying cause of dysphagia. 5 figures. 2 tables. 15 references. (AA-M). •

Summary: This article reviews the causes, complications, and nursing strategies for patients with swallowing difficulties (dysphagia). Often responsible for monitoring patients during meals, nurses can be the first to detect signs and symptoms of this condition. Appropriate nursing interventions can prevent life threatening complications such as aspiration, which often results in pneumonia. The author discusses the patients who are most at risk of dysphagia, the complications of swallowing problems, patient care strategies (concentration during meals, positioning), food considerations (temperature, presentation, consistency), medication concerns, and additional management techniques.

Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 32887-4800. Summary: This article reviews the contemporary approach to diagnosis of the patient with dysphagia (difficulty in swallowing). The diagnostic sequence used when working with a new patient with symptoms of dysphagia begins with a general medical history, followed by a focused history of the swallowing problem. After the history taking comes a thorough examination of the head and neck. At this point, many experienced clinicians may be able to accurately predict the nature and severity of the swallowing disorder. However, some sort of swallowing study is appropriate to complete the work up by revealing details of the patient's actual swallowing physiology. The author guides readers through the use of the barium swallow and the videofluoroscopic swallowing study, manometry, manofluorography (a combination of manometry and videofluoroscopic), bolus scintigraphy, ultrasonography, and a new methodology, the videoendoscopic swallowing study (VESS). 10 figures. 2 tables. 27 references.

Summary: This article reviews the evaluation of disorders of feeding and swallowing in children (pediatric dysphagia), serious and potentially fatal problems. Among infants, particularly those born prematurely, aspiration due to dysphagia may lead to severe pulmonary compromise, and impaired oral and pharyngeal function may rapidly result in failure to thrive. In other children, avoidance behaviors and inadequate intake may lead to chronic malnutrition. Topics include the expected stages of swallow development for each age group, classifying disorders of feeding and swallowing in children, medical history in children with disordered feeding and swallowing, the assessment of swallowing in children (including clinical or bedside evaluations), the use of imaging (radiography, ultrasound, and fiberoptic endoscopy), and otolaryngologic assessment. The authors conclude that disorders of feeding and swallowing in children are most common among children with congenital anomalies of the head and neck, and in those with congenital or acquired neuromuscular impairment. Bedside clinical assessment is often sufficient to make a diagnosis or preliminary feeding recommendations. However, videofluoroscopy is the study of choice for complete evaluation of the feeding and swallowing process. 5 figures. 8 references. •

Summary: This article, from a professional newsletter for speech language pathologists and audiologists, outlines current advances in dysphagia research, notably the development of a diagnostic test called flexible endoscopic evaluation of swallowing with sensory testing (FEESST). The FEESST method offers assessment of both the motor and sensory components of swallowing, thus providing an advance in specialized dysphagia management. FEESST allows clinicians to visualize the laryngopharynx during deglutition (swallowing) and to identify patients who are at risk for developing aspiration pneumonia. The article describes the indications for this evaluation method, the equipment and supplies used, risk factors associated with the examination, the types of patients that may benefit from FEESST, cost considerations, and the problem of aspiration pneumonia. The article concludes with the contact information for the primary clinician interviewed in the article.

[email protected]. Summary: This article, the third in a series on surgery of the gastrointestinal (GI) tract, describes cricomyotomy for pharyngeal swallowing disorders. Cricopharyngeal dysphagia may be due to muscular, neurologic, or anatomic abnormalities. The condition also increases in incidence with advancing age and may be due to a fibrotic cricopharyngeal muscle that will not open sufficiently to allow the easy passage of a swallowed bolus. A normal muscle may also cause relative obstruction to a food bolus in the presence of weak or uncoordinated pharyngeal muscle action after strokes. Failure of the food bolus to pass the cricopharyngeal sphincter often results in

aspiration. Cricopharyngeal myotomy has low morbidity and mortality and entails only a short hospital stay. It may offer complete relief or allow satisfactory swallowing without aspiration in many selected patients. Patients are selected carefully for myotomy after radiologic and manometric evaluation of the cricopharyngeal swallowing mechanism. The results of myotomy in patients with an isolated cricopharyngeal muscle abnormality are uniformly good. In patients with swallowing disorders after strokes, swallowing may improve with time and swallowing therapy. The results of cricopharyngeal myotomy are not as predictably good in these patients as in those with muscle disease, but improvement will be obtained in up to 60 percent of patients who have not responded to conservative therapy. 5 figures. 7 tables. 12 references.

New Diets for People With Dysphagia: Caregivers' Attitudes and Presentation of Food Can Make a Program Succeed or Fail Source: Provider. 53-55. April 1999. Summary: This journal article addresses the problem of serving enjoyable, appetizing, and nutritious food to long-term care residents who have difficulty swallowing. Dysphagia, a swallowing disorder, may result from stroke or neurological disorders such as Parkinson's disease, multiple sclerosis, or Alzheimer's disease. Traditionally, physicians have recommended mechanically altered food to dysphagia patients, which lack eye appeal and may reduce appetite. The authors discuss how providers can design alternative diets that are appealing and diverse and that fulfill clinical mandates. They show how a culinary team consisting of a professional chef and a registered dietician works together to create a new menu. Staff education and recognition, culinary training manuals or seminars, and a commitment to excellent food contribute to the success of a new food program. Photograph.

Assessment of Oral, Pharyngeal and Esophageal Dysphagia in Elderly Persons Source: Physical and Occupational Therapy in Geriatrics. 14(4): 1-25. 1996. Summary: This journal article describes methods used to assess swallowing disorders in older people. It describes three phases of swallowing (oral preparatory, pharyngeal, esophageal) and the methodologies commonly used in the clinical setting to assess difficulties in each phase. The purpose, procedures, limitations, and drawbacks of each methodology are discussed, with particular attention to possible complications caused by age-related changes and disorders such as dementia. The methods available for assessment of the oral preparatory phase are limited to two feeding skill profiles that were designed for use with children and have not been validated for older people. The methods used for assessment of the pharyngeal phase include videofluoroscopy, fiberoptic endoscopy, pharyngeal manometry, the Exeter Dysphagia Assessment Technique, cervical auscultation, scintigraphy, and timed drinking tests. Those used for assessment of the esophageal phase include esophageal manometry and a bedside, questionnaire-based assessment. 1 table, 93 references.

Dysphagia, Headache, and Dizziness as Symptoms of Cervical Spine Disorders Source: Revue du Rhumatisme (English Edition). 65(5): 346-351. May 1998. Summary: This journal article provides health professionals with information on recognizing dysphagia, headache, and dizziness as symptoms of cervical spine disorders. Much evidence points to the causal relationship between dysphagia and lesions of the cervical spine. In many cases, dysphagia is caused by a lesion or bony excrescence arising from the anterior aspect of the cervical spine. Sometimes, dysphagia is caused by anterior cervical disk herniation. Other causes include spondylolisthesis, discal calcification, and trauma-related hyperlordosis of the cervical spine. Conservative treatment is usually recommended. Corticosteroids, nonsteroidal anti-inflammatory drugs, spasm-relieving agents, and precautions during meals are helpful. Evidence that lesions of the cervical spine cause headaches is unclear, although lesions of the atlantooccipital, atlantoaxoidal, and C2-C3 joints resulting from osteoarthritis have been shown to cause headaches. Occipital neuralgia has been reported in patients who have septic or rheumatoid arthritis and ankylosing spondylitis. Cervicogenic headache refers to unilateral pain originating in the neck and radiating to the oculofrontotemporal area. There is no evidence that this type of headache originates in the cervical spine. Dizziness not attributable to vertebrobasilar insufficiency may be caused by cervical spine lesions in some patients; however, an extensive search for other causes is needed. 54 references.

Summary: This review article discusses the current state of dysphagia management, including evaluation and treatment of swallowing disorders arising from neurologic disorders and surgical interventions. The modified barium swallow and the flexible endoscopic assessment of swallowing are the two most common instrumental evaluations of swallowing. Other useful tests include scintigraphy, ultrasonography and pulse oximetry. Although current evaluative methods rely on instrumental tests, the efficacy of dysphagia testing remains controversial. New treatments, or modifications of previous techniques, for swallowing disorders include the use of botulinum toxin, pharmacologic approaches, modification of bolus consistencies, and surgeries to improve vocal fold closure. Other behavioral techniques include thermal stimulation, maneuvers to increase bolus propulsion, and postural techniques. Although most reports indicate the positive effects of treatment, controlled prospective studies to suggest the amount of treatment and the best time to initiate treatments are sparse. The discipline of dysphagia continues to evolve; however, definitive diagnostic and treatment protocols remain to be determined for many swallowing disorders. 4 tables. 62 references.

Summary: This special supplement of Nutrition and Clinical Practice reports the proceedings of the Fourth Annual Ross Medical Nutrition and Device Roundtable, which focused on dysphagia (swallowing disorders). The conference describes patient populations who are at risk for dysphagia, various clinical and instrumental diagnostic procedures, the health care continuum, aging, medications, surgical procedures and other medical treatments, aspiration and pneumonia, nursing, nutritional issues, viscosity and texture of diet, and the present status of research in dysphagia. One of the basic yet essential components in improving the health of patients with dysphagia is nutritional care and management. In the introduction, the editor notes that nutrition treatment implies more than the diet; it includes many other factors, such as how the food is presented, the ingredients and nutritive value of the diet, and matching individuals with specific needs to an appropriate diet. The supplement emphasizes the importance of a multidisciplinary approach to dysphagia and patient care management. Each article concludes with a list of references, and, in some case, a reprint of the associated panel discussion from the conference. •

Tel: (215) 521-8300. Web site: http://www.laryngoscope.com. Available online on a pay-per- view basis. Summary: This study compared the effectiveness of the modified barium swallow (MBS) test and the flexible endoscopic evaluation of swallowing with sensory testing (FEESST) in diagnosing dysphagia, which has been associated with susceptibility to aspiration pneumonia. A total of 126 patients were tested using one of the two methods as part of a program to control dysphagia through dietary and behavior management. The incidence of pneumonia and pneumonia-free intervals were tracked for 76 patients receiving BMS and 50 patients receiving FEESST examinations. Eighteen percent of the BMS patients and 12 percent of the FEESST patients contracted pneumonia. Patients in the MBS sample were pneumonia-free for an average of 47 days, and patients in the FEESST group were pneumonia-free for 39 days. The differences between the groups were not statistically significant. The author concludes that neither test is more effective than the other.

Federally Funded Research on Dysphagia The U.S. Government supports a variety of research studies relating to dysphagia. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to dysphagia. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore dysphagia. The following is typical of the type of information found when searching the CRISP database for dysphagia: •
Project Title: AGING OF THE INTRINSIC LARYNGEAL MUSCLES Principal Investigator & Institution: Andrade, Francisco H.; Assistant Professor; Neurology; Case Western Reserve University 10900 Euclid Ave Cleveland, Oh 44106 Timing: Fiscal Year 2004; Project Start 01-JAN-2004; Project End 31-DEC-2005 Summary: (provided by applicant): As the population of the United States grows older, age-induced dysfunction of the different motor systems becomes a more important cause of diminishing quality of life, increasing health costs, and even institutionalization. The larynx is part of a complex motor system that separates the airways from the digestive tract. It protects the airway during swallowing and ventilation, serves as a pressure valve for straining and airway protective reflexes, and is a resonance box for phonation. In the elderly, atrophy and dysfunction of the larynx and its intrinsic musculature compromise voice quality and impair the ability to communicate and remain socially engaged. Laryngeal dysfunction may also cause dysphagia and increase the risk of aspiration. Our preliminary findings indicate that the intrinsic laryngeal muscles are significantly altered by age; unfortunately, the biology of these small muscles has not been systematically studied, and the effects of aging on their function remain largely unknown. Because of their strategic role for ventilation, swallowing and airway protection, it is likely that even small age-related functional deficits in the intrinsic laryngeal muscles may translate to higher morbidity and mortality. In consequence, the objective of this project is to understand the cellular mechanisms that explain the effects of aging on the function of the laryngeal muscles. Combining well-established functional and biochemical assays with the Fischer 344Brown Norway hybrid rat model of aging, we will determine (1) how age changes the functional characteristics of the intrinsic laryngeal muscles; (2) how aging alters the cytosolic calcium kinetics of these muscles; and (3) the changes in mitochondrial capacity induced by aging in the intrinsic laryngeal muscles and that may render the muscles more fatigable. We expect that this project will obtain significant new information on the effects of age on laryngeal muscle function, and define the most likely cellular targets for interventions designed to retard, prevent, and even reverse the

Project Title: BIOMECHANICS OF ESOPHAGEAL WALL AND VISCERAL SENSATION Principal Investigator & Institution: Mittal, Ravinder K.; Professor of Medicine; Veterans Medical Research Fdn/San Diego Foundation of San Diego San Diego, Ca 92161 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 30-JUN-2005 Summary: (provided by applicant): The biomechanical properties of the esophagus have relevance to its motor and sensory function. These properties have been studied in the animals and humans by several investigators using various techniques. However, there are limitations with each of these techniques. We have developed a novel system of balloon ultrasonography that measures esophageal pressure, radius and wall thickness simultaneously, in vivo, in humans. Our technique, therefore, allows accurate measurement of the wall stress, strain and elastic modulus (wall rigidity) on a continuous time basis. Our preliminary data show that in normal subjects there is a close temporal correlation between increase in intraluminal pressure and esophageal wall thickness, which allows the esophagus to maintain a low wall stress. Patients with motility disorders of the esophagus have a thicker esophageal muscularis propria compared to normal subjects. We hypothesize that difference in the biomechanical properties of the esophageal wall between normal subjects and patients is the reason for impaired esophageal transport and dysphagia in patients with motility disorders of the esophagus. The current understanding is that hypersensitivity of the esophagus is the cause of esophageal pain. Patients with presumed esophageal pain respond to distension of the esophagus at lower balloon volumes than normal subjects. The site of esophageal hypersensitivity may be at either the peripheral (esophageal wall) or at the central level (CNS). The latter is currently the favored site. The differences in the biomechanical properties of the esophageal wall in patients and normal subjects may result in different wall stress and strain in response to the same volume of distension. We hypothesize that differences in the biomechanical properties of the esophagus may be the reason for a hypersensitive esophagus. The specific aims of our studies are: 1: In vitro validation of the novel technique of balloon-ultrasonography. 2: To determine biomechanical properties of the esophagus in normal human subjects using balloon ultrasonography and to determine the relationship between esophageal pain and its biomechanical properties. 3: To define the abnormalities of muscularis propria thickness in patients with primary motility disorders of the esophagus. 4: To determine the biomechanical properties of the esophageal wall in patients with a normal and thick muscularis propria and its relationship to esophageal hypersensitivity. 5: To study biomechanics of the esophageal wall in patients with esophageal dysphagia. We believe that our observations have important implications in understanding the mechanisms of esophageal motor and sensory function in healthy and diseased states. Furthermore, the principles discussed in the esophagus may be applicable to the understanding of visceral hypersensitivity seen in irritable bowel syndrome and other functional disorders of the GI tract.

Studies
27
Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): Pharyngeal phase dysphagia can be a severe and costly side effect of stroke and chemoradiation therapy for head and neck cancer, causing the patient to regularly aspirate and be unable to eat by mouth. A major subset of pharyngeal phase dysphagia is caused by inability to move the bolus completely through the upper esophageal sphincter (UES) during swallowing. Available therapy for this condition is limited and yields a degree of success, but a new therapy procedure, the Shaker exercise, offers an exciting new opportunity to rehabilitate these patients perhaps more effectively and efficiently than the usual therapy program. The 5 year project we are proposing is a randomized clinical trial of these two therapies in patients with severe pharyngeal phase dysphagia with inability to move the bolus completely through the UES. The patients must be non-oral for at least three months because of aspiration of residue from either or both the valleculae and pyriform sinuses. The primary objective of this project is to identify which of two therapy programs, the Shaker exercise versus traditional therapy, results in the largest number of stable, nonoral dysphagic patients who can swallow safely and return to full oral feeding after 6 weeks of intervention. The study is powered adequately so that this aim can be tested separately for post chemoradiation therapy, head and neck cancer, and stroke patients. Our outcome measure is return to oral feeding, i.e., 100-percent of nutrition and hydration by mouth. Our secondary objectives are to: 1) determine in a descriptive manner whether patients with residue in the pyriform sinuses who aspirate the residue after the swallow respond better, i.e., a higher percentage of them can return to 100percent oral intake, than patients with residue in the valleculae or patients with residue in both locations who aspirate after the swallow and thus to define the spectrum of indications for the proposed exercise programs in the two studied groups of dysphagic patients, and 2) define the pathophysiological elements which change as a result of each therapy program including changes in a. anteroposterior and lateral diameter of maximum deglutitive UES opening, and b. maximum deglutitive laryngeal anterior and superior excursions.

Project Title: COORDINATION OF RESPIRATION AND DEGLUTITION Principal Investigator & Institution: Perlman, Adrienne L.; Professor; Speech and Hearing Science; University of Illinois Urbana-Champaign Henry Administration Bldg Champaign, Il 61820 Timing: Fiscal Year 2002; Project Start 15-JAN-2000; Project End 31-DEC-2003 Summary: The close proximity of the larynx to the entrance of the esophagus, and the common pathway through the pharynx that both air and a swallowed bolus must traverse, require that swallowing and respiration be well coordinated. Discoordination can result in the aspiration of food, liquid, or oral secretions consequent risk of severe respiratory complications. Despite its critical function, the coordination of respiration with swallowing is not well-understood either in healthy individuals or in persons, such as stroke patients, who are known to be at high risk for developing aspiration pneumonia. Using respirodeglutometry, this research will characterize the joint timing of respiration with the swallow and simultaneously record respiratory airflow, submental surface electromyography, and swallow-associated acoustic signals. Two hundred forty normal subjects (120 male, 120 female) in five groups ranging from 3 to 85 years-of-age, and sixty medically stable stroke patients, will be studied. Respirodeglutometric (RDT) output will be digitized at 1000 samples/sec/channel while subjects swallow pre-measured 5, 10, and 15 ml volumes of water and pudding.

Dysphagia
For all subjects and for each swallow, the direction of respiration preceding and following the swallow, the duration of deglutition apnea, and five additional RDT temporal measures will be obtained. All stroke patients will also be seen for videofluoroscopic assessment within 24 hours of the RDT evaluation in order to directly assess the oral and pharyngeal stages of their swallow and to identify various indicators of dysphagia, including the presence/absence of laryngeal penetration and aspiration. Analysis will address i) effects of size and viscosity of swallowed material on timing of RDT measured events within the swallow, ii) changes in the coordination of respiration with swallowing in healthy subjects across the lifespan, iii) age and gender adjusted effects of stroke on such coordination, iv) adaptations of coordination by healthy subjects and stroke patients to feeding by a caregiver relative to self-feeding, and v) the relationship in stroke patients of videofluoroscopically- observed oropharyngeal dysphasia and aspiration to aberrant respiratory-swallowing patterns. Findings from this research can have a profound effect on patient evaluation procedures as well as on behavioral management techniques, clinical outcome goals, and medical costs for stroke patients.

Project Title: DEPRESSION AND END OF LIFE CARE IN ALS Principal Investigator & Institution: Albert, Steven M.; Gertrude H Sergievsky Center; Columbia University Health Sciences New York, Ny 10032 Timing: Fiscal Year 2002; Project Start 20-AUG-2000; Project End 31-JUL-2004 Summary: (Adapted from investigator's abstract) Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that results in death, usually from respiratory insufficiency or aspiration, within 3 to 5 years of diagnosis. The disease affects all voluntary motor function except eye movement and sphincter control. In the final 6-9 months of life, patients must choose (either explicitly or by default) palliation or tracheostomy and long-term mechanical ventilation (LTMV). In this 4 year project, we will follow 140 patients diagnosed with definite or probable ALS who face a high likelihood of death within 6-9 months, as defined by poor pulmonary function, dysphagia and weight loss, or hospice certification or eligibility. These patients will be followed with bimonthly in-home assessments, and with an additional assessment in the last weeks of life. We will also interview the primary family caregiver on the same schedule and once after the patient's death, as well as conduct a survey of medical providers' influence on end-of-life decisions. In this observational cohort study, we propose (1) to assess the prevalence and course of depressive disorders and symptoms in ALS patients in the final months of life and its relevance for decision-making at the end of life; (2) to identify predictors of tracheostomy/LTMV use; (3) to examine the degree to which patients and families take steps to control the timing of death by adopting a strict palliative care regime; and (4) to examine associations between patient and caregiver distress in the final months of life. Key questions include the following: Do levels of distress and depressive symptoms increase as patients approach death, and does this relationship differ according to choice of palliative care or LTMV? What maintains hope in these patients, who are, in a medical sense, hopelessly ill? Of patients who receive LTMV, in what proportion is LTMV consciously planning for, as opposed to an unplanned emergency procedure? Is patient mental health or caregiver burden associated with decisions to forego or undergo LTMV? To what degree does use of noninvasive, temporary nasal ventilation (Bi-Pap) prevent use of LTMV? These questions have not been investigated in a prospective study. We will be able to address them through repeated, detailed assessments of patients and caregivers. This information will

Project Title: DIFFERENCES IN SWALLOW MECHANICS IN INFANTS Principal Investigator & Institution: German, Rebecca Z.; Professor; Biological Sciences; University of Cincinnati 2624 Clifton Ave Cincinnati, Oh 45221 Timing: Fiscal Year 2002; Project Start 01-JUL-1998; Project End 31-JUL-2006 Summary: (provided by applicant): Swallowing requires the coordination of a large number of muscles; this complexity arises partly from the need for airway protection. In the previous funding period, we added to the understanding of muscle activity and oropharyngeal kinematics in infant deglutition. However, the role of the majority of muscles during emptying of the valleculae and in the transport of the bolus past the laryngeal opening or the natural stimuli that initiate the emptying of the valleculae over maturation is not well understood. Our preliminary data suggest that two distinct pathways of bolus movement exist, either around the epiglottis/laryngeal opening (in the newborn) or over it (by the age of weaning). However the timing of the transition, from one path to the other and the associated changes in the kinematics or motor patterns, are unknown. The decerebrate pig is an excellent model for studying vallecular emptying because this phase of the swallow can be isolated experimentally. We propose to apply our existing techniques both to this model and to intact animals, in order to answer the following questions. What natural stimuli initiate vallecular emptying, and do they change during maturation? What is the pattern of muscle activity during vallecular emptying in terms of the order and amplitude of muscle activation? Does change in the consistency of the bolus alter the motor pattern during vallecular emptying, and does this change over developmental time? Does epiglottal movement result from: (i) direct muscle contraction; (ii) indirect movement of the rest of the larynx, (iii) the mechanical action of food on the epiglottis, or a combination of all three? Current studies of human dysphagia and rehabilitation rely heavily on several older studies of oral function in adult man and animal; these studies did not have the means to examine the ontogeny of vallecular function in detail. The proposed study of the maturation of motor patterns will provide an important baseline for treatment strategies aimed at human infant dysphagia.

Project Title: EFFECTS OF LSVT ON DYSPHAGIA IN PARKINSON'S DISEASE Principal Investigator & Institution: Logemann, Jerilyn A.; Professor; Communication Scis & Disorders; Northwestern University 633 Clark Street Evanston, Il 60208 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2004 Summary: (provided by applicant): Lee Silverman Voice Treatment (LSVT) has shown promise in improving swallow, as well as voice and speech. This project is designed to define the effects of LSVT on swallow in patients who exhibit VFG verified aspiration on any food volume or viscosity. Thirty patients with idiopathic Parkinson's disease, who aspirate (with or without cough response) on any food consistency, will serve as subjects in this study. When identified clinically as at-risk for aspiration, patients will receive a modified barium swallow on a standard protocol, followed by randomization to immediate LSVT treatment for 1-month (4 sessions per-week for 4-weeks) or delayed LSVT beginning 1-month after the first group's therapy is completed. Thus, the comparison of critical interest is therapy vs. no therapy. The delayed group will serve as
30
Dysphagia
the no therapy arm. Patients in both arms will receive instructions on diet and posture modification, as necessary, based on the results of VFG. Patients will receive no other swallowing therapy or voice or speech therapy during this 2-month period when both groups receive treatment. After completion of one-month of therapy, patients will receive a modified barium swallow assessment to document change. Medication schedules will remain unchanged throughout the study, and patients will receive their modified barium swallow studies at the same time of day relative to medication both pre- and post-LSVT treatment. The outcome measure will be the elimination of aspiration. We will also define, as secondary measures, the changes in bolus transit times, the observation of percentage residue in the mouth and pharynx, the frequency of swallowing motility disorders and the temporal measures of swallow. These will all serve as explanatory variables for changes in frequency of occurrence of aspiration. This application proposes to generate pilot data on the effects of LSVT on aspiration, a potentially dangerous and costly side effect of dysphagia in Parkinson's disease.

Project Title: FEEDING BEHAVIORS & ENERGY COST IN INFANTS WITH CHD Principal Investigator & Institution: Medoff-Cooper, Barbara S.; Helen M Shearer Professor in Nutrition; None; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 01-JUN-1994; Project End 31-MAY-2007 Summary: (provided by applicant) This proposal requests continued support for a NINR funded study that had been entitled: Nutritive sucking: Physiological and Behavioral correlates. In the present proposal, we (1) deepen our analysis of feeding organization by integrating measures of sucking, swallowing and breathing over the course of full meals and (2) characterize the feeding patterns of another at-risk population - infants with congenital heart disease (CHD), and (3) relate feeding performance and energy expenditure to problems in growth and development over the first year of life in CHD infants. These infants are often difficult to feel, even when their surgery has improved their cardiac function. Indeed, the success of the surgery often unmasks their severe nutritional syndrome, failure to thrive (FTT). To address this important clinical problem, we propose to measure feeding performance and energy expenditures over the first hear of life in 120 infants who have undergone surgery during the first month of life to correct or palliate sever cardiac abnormalities and 60 healthy newborn controls. The specific aims of our proposed study are as follows: 1) to establish which aspects of feeding performance (e.g. suck/swallow/breathe coordination, temporal patterning of sucking with meals, suck pressure generation, adaptation to variation in flow rate) are most subject to disruption in CHD infant after corrective or palliative surgery; 2) to determine infants' pattern of oropharyngeal adaptation to variations in the flow rate through an artificial nipple, and whether flow rate adjustment represents a viable strategy for improving meal size outcomes; and 3) to determine the relative contributions of disrupted feeding organization and (potentially elevated) energy expenditure to unfavorable growth outcomes, i.e. (i) relate disrupted feeding to growth, (ii) relate energy expenditure to growth, and (iii) integrate energetic and feeding-performance characteristics in a predictive model of failure to thrive in infants with CHD. This study addresses what we believe is the central role of feeding organization in the nutritional status of this patient population; as such, it represents an approach toward early identification, based on feeding performance and energetic profiles, of infants most at risk for developing FTT by the age of one.

Project Title: GASTRIC FEEDING TUBES: PATIENT/FAMILY/PROVIDER VIEWS Principal Investigator & Institution: Carey, Timothy S.; Professor of Medicine; Medicine; University of North Carolina Chapel Hill Aob 104 Airport Drive Cb#1350 Chapel Hill, Nc 27599 Timing: Fiscal Year 2002; Project Start 01-SEP-2000; Project End 28-FEB-2004 Summary: We propose a two and a half year prospective study of predominantly older individuals with neurologic diseases, head and neck cancer, and severe medical illness who receive gastric feeding tubes. We wish to define the outcomes of this treatment from a patient and caregiver perspectives. The number of gastrostomy feeding tubes used for the Medicare population has grown rapidly, more than doubling during the past decade. The diseases that cause dysphagia also shorten life expectancy, and cause other deficits in cognitive, physical and social functioning. Nutrition, hydration, and the social context of eating are fundamental elements of comfort care for these patients near the end of life. Feeding is a primary act of care giving and nurture, yet tube feedings have become a form of life- sustaining treatment fraught with ethical implications for patients and caregivers. Previous studies have emphasized medical outcomes of this procedure. No prior study has examined outcomes of this treatment from the patient and caregiver perspective. Our overall aims are: 1. Describe the expectations of patient, family, health care providers regarding the benefits of gastric feeding tubes on: patient longevity, patient functioning, likelihood of hospitalization for pneumonia. 2. Compare perceived benefits of gastric feeding tubes at the time of placement to perceived benefits such as outcomes of survival, functional status and pneumonia at 3 and 6 month followup, from the perspectives of patient, family and health care providers, including physicians and nurses. 3. Describe the true outcomes of patient survival, pneumonia incidence and functional status among those who survive for 3 and 6 months after insertion of the feeding tube. We will recruit 200 patients receiving gastrostomy from two North Carolina hospitals: a university tertiary care center, and a large community hospital. Interviews will be conducted with physicians, nurses, family caregivers and patients shortly following the procedure with follow-up interviews at 3 and 6 months. The interview will include assessment of functional status, perceived benefit, and expectations regarding longevity and future function. These multiple perspectives on the use of gastrostomy tubes will allow a much more complete portrait of the benefits and limitations of this increasingly utilized supportive therapy at the end of life.

Specifically, it is in our plan to develop an expert system based upon the use of recent advances in neural networks, fuzzy logic and other computational algorithms. Although several researchers in communication disorders have already claimed some initial success with these recently
32
Dysphagia
emerging tools, a thorough investigation is warranted to tap the full potential of these algorithms. It is anticipated that the proposed system will be capable of objectively analyzing communication disorders based on multi-dimensional measures of speech fluency, acoustic variables, and some selected physiologic assessments. Specifically, the proposed system will be applied to differentiate between the set of data from normal and speech-language disordered individuals so that the burden of perceptual judgment by the clinician is objectively resolved by the expert system. There is significant evidence from clinical experience that this corpus of measures contain the information necessary to make the differential diagnosis. However, this information has not been mined successfully through objective means because of the multitude of simultaneous variables present in these tasks, and lack of sufficient technical thrust in this province. It is expected that this project will include a wide variety of communication disorders such as: stuttering, spasmodic dysphonia, aphasia, apraxia and dysarthria. This technology is expected to benefit clinicians in objective decision-making. Currently individual clinicians perform this task. It is subjective and time consuming. The clinical decisions on treatment methods depend upon the nature and extent of the training and any biases inherent in that training of individual clinicians. This limitation may be overcome by the unlimited learning potential of the computer. Another aim of this project is to develop a model of communication disorders based upon the underlying mechanisms of the expert system. It is anticipated that such a model will provide helpful insights into the pathophysiology of communication disorders. Furthermore, the results of this research is expected to improve the current knowledge of the comparative strengths and weaknesses of existing algorithms and develop means to combine the advantages of several computational methods within one operating system.

Project Title: LINGUAL MECHANICAL FUNCTION DURING SWALLOWING Principal Investigator & Institution: Gilbert, Richard J.; Mechanical Engineering; Massachusetts Institute of Technology Room E19-750 Cambridge, Ma 02139 Timing: Fiscal Year 2003; Project Start 12-SEP-2003; Project End 31-AUG-2006 Summary: (provided by applicant): The human tongue is an intricately configured muscular organ that plays a vital role during the physiological act of swallowing. During normal deglutition, the tongue first configures, then propels the ingested bolus from the oral cavity retrograde to the pharynx. From a clinical perspective, disorders of lingual function are exceedingly common in the elderly, in association with common neurological diseases, such as stroke, Parkinson's disease, and dementia, and are responsible for impaired nutrition and increased risk of aspiration pneumonia in these patient populations. Notwithstanding, there is minimal understanding of the way in which lingual muscular structure contributes to physiological function. The study of lingual mechanics has long been hampered by the complex myoarchitecture of the tissue and its material properties. As a result, mechanical function cannot be determined solely from global changes of shape, but necessitates the study of intramural dynamics. Our overall hypothesis is that the tongue functions as a muscular hydrostat, a unique structure in the human body, with the ability to both create motion and to provide the skeletal support for that motion. In order to test this hypothesis in the setting of human swallowing, we have considered the tongue from the perspective of a material continuum, and have thus depicted the tissue in terms of local fiber organization and strain. This project will study the quantitative relationship between three-dimensional myoarchitecture and regional mechanics during human swallowing. Our experimental approach uses non-invasive nuclear magnetic resonance imaging techniques to discern

33
patterns of myoarchitecture and regional mechanics in vivo. In Specific Aim 1, the threedimensional myoarchitecture of the tongue will be studied through the depiction of the local second order diffusion tensor derived from magnetic resonance imaging. In Specific Aim 2, the quantitative relationship between muscle fiber architecture and regional strain in association with swallowing will be determined by linkage of the structural measures with tagged magnetization. In Specific Aim 3, the regional mechanical adaptation to varying bolus volume and viscosity will be studied through combined diffusion tensor and tagged magnetization imaging under varying load conditions. This project should result in an improved understanding of structurefunction relationships for the human tongue, and related human muscular hydrostats. It is anticipated that this understanding will result in novel hypotheses of pathological lingual function for patients with oropharyngeal dysphagia.

Project Title: NATURAL HISTORY, SEARCH FOR A MARKER AND THERAPY Principal Investigator & Institution: Sakkubai, Naidu; Kennedy Krieger Research Institute, Inc. Baltimore, Md 21205 Timing: Fiscal Year 2002 Summary: The goal of this project is to define the natural history, identify a diagnostic marker, understand the mechanism of neuronal dysfunction, and apply specific therapies early in the evolution of the disease to improve neurological status in Rett syndrome (RS). Based on the postulate that RS is a disorder of early brain growth, AIM 1 focuses on the identification of younger patients and delineation of early clinical features. Familial cases and their pedigrees will be documented in search of a genetic abnormality. Cases identified in Aim 1 will be a vital resource for all projects. In Aim 2 gene(s) defective in RS will be sought by classical cytogenetic approaches, and by representational difference analysis (RDA). Aim 2 will also search for proteins, and expressed genes that have up- or down regulated in RS, which may serve as a molecular fingerprint for the disease. Aim 3 is designed to study olfactory receptor neurons (ORNs) obtained from biopsies of olfactory neuroepithelium in RS girls, and compared to ORNs from normal and disease controls. A cell culture approach will provide direct access to RS neurons early in the course of the disease, and permit study of the evolution of neuronal defects in this disorder. In Aim 4 therapeutic interventions will attempt to prevent the devastating consequences of increased glutamate NMDA, and AMPA receptor induced neuronal injury by specific treatments with receptor antagonists, dextromethorphan and topiramate. To compensate for the significant reductions in choline acetyltransferase levels, treatment with an acetylcholine esterase inhibitordonepezil hydrochloride- to improve cognition will be tested. Efficacy of treatment will be monitored by clinical and neuroimaging techniques. Careful study of the nutritional status, and the role of dysphagia in growth failure will be examined in the light of therapeutic interventions. Use of growth factors or gene therapy will be considered when efficacy is established in the animal model. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Dysphagia
Summary: Understanding the role of the nervous system in feeding control is an important goal for basic and clinical science. In humans, the excessive feeding associated with some obesities increases the probability of diabetes, hypertension, and heart disease. Other feeding-related problems (failure to thrive, early satiety, dyspepsia, gastroesophageal reflux, dysphagia, cachexia, anorexia, bulimia) account for a significant portion of health-care expenditures in the U.S. Clearly, basic research into the location and operating characteristics of the neural substrates that control feeding behavior is essential for: an understanding of the basic physiology of intake control, an appreciation of the CNS underpinnings of various feeding pathologies, and the development of effective pharmacological treatments. We believe, as did Sherrington that the most fruitful approach to analyzing a complex distributed neural control system, such as that controlling feeding behavior, begins at the anatomical level(s) of the relevant sensory inputs and motor outputs. It is a given that many of the relevant sensory inputs (taste, visceral) enter, and all of the consummatory motor outputs (somatic and autonomic) emerge, at the level of the caudal brainstem (CBS). To address the issue of integration, we developed a chronic decerebrate rat (CD) model and have provided data that call attention to a CBS contribution to intake control. When the CD and intact rat respond similarly to selective treatments we can infer that the CBS-neurally disconnected from the hypothalamus long held to be the seat of intake control-is sufficient for all elements of the integrated response. In addition, with 4th icv infusion of orexigenic agents we will explore the relevance of CBS receptor systems to the integrated behavioral response of the neurologically intact rat. Finally, we approach a more anatomically resolved analysis of the intake-relevance of specific CBS structures through intraparenchymal infusion, cFos immunohistochemical, and NPY mRNA expression studies. The proposed experiments address the following specific aims evaluate: (1) the sufficiency of the CBS for response to signals that underlie short-term intake control; (2) the role of CBS structures in long-term intake control and (3) the relevance of CBS receptors to the feeding response evoked by selected orexigenic agents.

Project Title: ORAL MUCOSITIS - FORMULATIONS FOR PALLIATION AND THERAPY Principal Investigator & Institution: Squier, Christopher A.; Dows Inst for Dental Research; University of Iowa Iowa City, Ia 52242 Timing: Fiscal Year 2002; Project Start 01-SEP-2000; Project End 31-AUG-2004 Summary: As the end-of-life approaches, the frequency of cancer increases markedly and it has been estimated that approximately 400,000 persons each year suffer oral side effects as a consequence of being treated for cancer therapy. Oral mucositis, an inflammatory condition of the oral mucosa leading to atrophy and ulceration, is one of the conditions frequently seen in those patients undergoing anti-cancer therapy. The lesions first appear in the mucosa of the soft palate, tongue and cheeks and as they

35
enlarge lead to extreme pain and dysphagia. As a consequence, there may be dehydration, a compromised nutritional status and a decreased quality of life. Palliation represents the standard clinical management so as to relieve symptoms and to check infections by means of anesthetic and antibiotic rinses. The hypothesis underlying the proposed research is that an appropriate occlusive muco-adhesive will not only reduce the symptoms of mucositis but could provide a means for effective adjunctive therapy of the condition. This application as an R21 exploratory and developmental grant seeks to develop an occlusive muco-adhesive in both gel and film form for the treatment of oral mucositis based on the biocompatible polymer, chitosan. The investigators intend to explore the effectiveness of the muco-adhesive in-vitro for delivering the antimicrobial and anti-inflammatory compounds necessary for palliative therapy of mucositis as well as for delivering bioactive peptides that may be able to provide protection or promote healing of the oral mucosa. Finally, they will investigate the acceptability, substantivity and durability of the muco-adhesive in vivo using normal mucosa and examine its effects on ulcerated mucosa in human volunteers. The study will involve collaborative studies between investigators with expertise in pharmaceutical technology, oral mucosal biology and oral medicine so as to develop palliative and therapeutic approaches to mucositis that would be of great benefit in improving the quality of life of those who are frequently at the end-of-life.

Project Title: PHYSIOLOGY OF SWALLOWING AND AIRWAY PROTECTION Principal Investigator & Institution: Paydarfar, David; Neurology; Univ Massachusetts Med Sch Worcester Office of Research Funding Worcester, Ma 01655
of
Timing: Fiscal Year 2003; Project Start 17-JUL-2003; Project End 30-JUN-2007 Summary: (provided by applicant): The long-term objective of our research is to better understand the neural control of swallowing and airway protection, to analyze the mechanisms of neurogenic dysphagia and aspiration in a controlled and systematic way, and to develop novel therapies based on pathogenesis. Our specific thesis is that laryngeal afferent feedback during swallowing facilitates the swallowing pattern generator's output to laryngeal and pharyngeal muscles. The internal branch of the superior laryngeal nerve (ISLN) is the principal sensory nerve of the larynx in humans. We propose to study how the ISLN regulates swallowing using nerve blocking and stimulating techniques in healthy subjects. Then, we plan to use what we learn about the ISLN to devise a method for improving glottic closure and pharyngeal contraction during swallowing in patients with dysphagia and aspiration due to cerebral lesions. Specific aims are: 1) To determine the physiological mechanism of aspiration in healthy subjects with ISLN blockade. Our preliminary studies show that the bolus usually penetrates the laryngeal inlet during the pharyngeal phase of swallowing. We will use electromygraphic, fluoroscopic and manometric techniques to analyze whether laryngeal penetration is due to reduced activation of laryngeal adductors, excessive intrapharyngeal pressure, or excessive inspiratory effort. 2) To test for extrafusal motor fibers in the ISLN. We will test the widely held view that the ISLN functions purely as an afferent by applying supramaximal current pulses to the isolated ISLN in patients undergoing laryngeal surgery. The presence of efferent fibers would be supported by a short latency (<5msec) laryngeal or pharyngeal motor response that is abolished following ISLN transection. 3) To optimize the activation of laryngeal adductors and pharyngeal constrictors evoked by ISLN stimulation. In awake healthy subjects with blocked ISLNs, we will attempt to reverse dysphagia and aspiration by electrically stimulating the ISLN central to the block, and the optimum stimuli that potentiate

swallowing without causing discomfort will be determined. 4) To test the feasibility of ISLN stimulation for treatment of neurogenic dysphagia and aspiration in patients with cerebral lesions. We will stimulate the ISLN (using optimum parameters from Aim 3) in patients with neurogenic dysphagia caused by focal cerebral damage, and we will test for improvement in swallowing and decrease in aspiration.

Principal Investigator & Institution: Bunker, Stephen N.; Implant Sciences Corporation 107 Audubon Rd, #5 Wakefield, Ma 01880 Timing: Fiscal Year 2003; Project Start 10-APR-2003; Project End 31-MAR-2004 Summary: (provided by applicant): Luminal obstructive symptoms such as dysphagia, vomitus, jaundice, or ileus are often the first symptoms noticed by patients or physicians and unfortunately, usually indicate an advanced stage of gastrointestinal disease associated with high mortality. Stenting of malignant biliary obstructions, performed on patients who are not candidates for curative surgery, is currently performed as palliative treatment with limited success. These stents fail one third of the time due to tumor growth through the struts of the stent. Our efforts will be focused on optimizing an iridium-192 radiation source for low dose rate permanent brachytherapy. This medical device would reduce costs and improve quality of life for the patient, because it requires only one intervention compared to other methods of palliative radiotherapy (HDR, EBRT), which require daily treatment regimens, often for weeks at a time. In addition, unlike EBRT, the dose to radiosensitive nontargeted tissue is greatly reduced. The proposed iridium-192 stent also has greatly improved radioopacity for enhancing accurate placement.

Project Title: RETT SYNDROME: NATURAL HISTORY AND TREATMENT Principal Investigator & Institution: Naidu, Sakkubai R.; Professor of Neurology and Pediatrics; Kennedy Krieger Research Institute, Inc. Baltimore, Md 21205 Timing: Fiscal Year 2003; Project Start 29-SEP-2003; Project End 30-JUN-2008 Summary: Patients with (70-80%) and those without mutations in MeCP2 gene are recognized to have the clinical features of Rett Syndrome. Although location of mutations can in part be correlated with the phenotype, they do not provide essential prognostic guidelines. We will attempt to delineate the molecular profiles of the various mutations that contribute to phenotypic variability. We will therefore correlate the clinical, gastrointestinal status, and neuroimaging changes (MRI, MRS) to levels of MeCP2, other methyl-binding domain proteins, and histone acetylation in Project 10, and with changes in olfactory receptor neurons in Project 9. We will also compare these changes to those with the phenotype but without mutations in MeCP2 to determine commonality in factors that may contribute to phenotypic similarities. In collaboration with Dr. Shemer (Israel), we will attempt to identify mutations in the promoter region of the MeCP2 gene in this latter group. The increased expression of the glutamatergic system in younger RS subjects leads us to treat patients below 15 years of age with dextromethorphan to block NMDA/glutamate receptors so as to prevent excitotoxicity and provide neuroprotection. To gain additional insight into the neurobiology of RS, we will conduct SPECT and PET studies in conjunction with Project 8 to delineate abnormalities in the cholinergic and glutamatergic systems that would provide future

37
therapeutic strategies in conjunction with studies in murine models in Project 5. Data from interaction between this and other projects will support our hypothesis that the phenotype of RS is the result of the unique effects of different MeCP2 mutations on specific neuronal populations and their interconnections during the dynamic phase of activity-dependant synaptic plasticity.

Project Title: STADARDIZED ASSESMENT OF SWALLOWING IMPAIRMENT Principal Investigator & Institution: Martin-Harris, Bonnie J.; Program Director; Otolaryngology-Head & Neck Surgery; Medical University of South Carolina 171 Ashley Ave Charleston, Sc 29425 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-APR-2008 Summary: (provided by applicant): The origin of the candidate's interest in this award mechanism stems from her career pathway that has included the integration of meaningful patient-oriented research into the clinical practice of evaluating and treating patients with swallowing disorders. The ultimate career goal of the candidate is to independently study and define functional swallowing impairment in adult patients with chronic pulmonary disease; however, there exists no validated or reliable measurement tool that permits the detection and quantification of swallowing impairment. A preliminary step toward the future pathway of independent swallowing research of patients with chronic pulmonary disease will require the development of a swallowing impairment measurement tool to be used during the modified barium swallowing evaluation. This tool (the MBSImP) will be clinically meaningful, practically implemented, reliably scored and sensitive to the presence of observed aspiration and to external indicators of health and quality of life. The structure of this award provides a vehicle to facilitate achievement of these short-term and long-term goals, and to the candidate's successful progression from clinical excellence and early stage clinical scientist to an independent clinical researcher. A complex reduction and aggregation strategy is proposed in the research plan that requires knowledge of applied multivariate statistical analyses, measurement theory and scale development, factor analysis and latent variable modeling. The candidate has included a mentor and external advisor to oversee a comprehensive curriculum in her Career Plan that includes didactic coursework and independent studies in the areas of statistical design, measurement, and factor analysis. Achievement of the candidate's stated career goals will require comprehensive understanding of the gross anatomy, physiology and pathophysiology of the upper aerodigestive tract in its entirety. Advanced competency as a clinical scientist in the area of swallowing and swallowing disorders will require understanding and application of overlapping swallowing physiology. While Dr. Martin-Harris demonstrates strong clinical proficiency in the clinical study of oropharyngeal swallowing dynamics and pulmonary function, she has insufficient knowledge of cervical, thoracic and distal esophageal structure and function. Patients with pulmonary disease and the prospective patients to be studied in the research plan often present with coexisting oropharyngeal and esophageal swallowing disorders. Therefore, the Candidate has included didactic coursework in advanced head, neck and chest anatomy, head and neck surgical rotations, and independent studies with her primary mentor, a world renowned clinician and researcher of esophageal swallowing disorders.

SWALLOWING--BUCCOPHARYNGEAL/ESOPHAGEAL
Principal Investigator & Institution: Altschuler, Steven M.; President & C.E.O.; Children's Hospital of Philadelphia 34Th St and Civic Ctr Blvd Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 01-APR-1999; Project End 31-MAR-2004 Summary: Swallowing, one of the more complex motor behaviors is programmed centrally by a medullary central pattern generator located in and around the nucleus of the solitary tract. The generation and modulation of neuronal patterned motor activity by the central pattern generator is dependent upon endogenous excitatory and inhibitory mechanisms and requisite central and peripheral afferent contacts. A significant imbalance in the relative contribution of excitation via NMDA and inhibition via GABA receptors may form the basis of dysfunctional swallowing present in neurological disease. Utilizing the rat as animal model, the anatomic basis of the excitatory and inhibitory processes critical to the coordination of the buccupharyngeal and esophageal phases of swallowing will be studied. Transsynaptic tracing with Pseudorabies Virus in conjunction with: (1) Fluorescent retrograde tracing will be utilized to study the anatomical connections between the buccopharyngeal and esophageal central pattern generator networks at the premotor neuron level; (2) In situ hybridization with oligonucleotide probes for the different N-Methyl-D-aspartate (NMDA) receptor subunits (R1, R2A- D) and GABAA receptor subunits (alpha1-6, beta1-3, gamma1-3, delta) will be utilized to determine the NMDA and GABAA receptor subunits expressed by our premotor neurons; (4) Immunocytochemistry for glutamate and GABA will be utilized to determined location and organization of glutaminergic and GABAergic neurons constituting and projecting to the central pattern generator; (5) Immunocytochemistry for NMDAR1 and GABAA alpha1 receptor subunit proteins will be utilized to investigate colocalization of the receptors on buccopharyngeal and esophageal premotor neurons (triple labeling method). Since alterations in excitatory and inhibitory synaptic function could contribute to the pathogenesis of swallowing disorders, these studies may have a direct bearing on the future clinical management of patients with dysphagia.

Project Title: THE ANATOMICAL BASIS OF HUMAN TONGUE BIOMECHANICS Principal Investigator & Institution: Sanders, Ira; Associate Professor; Otolaryngology; Mount Sinai School of Medicine of Nyu of New York University New York, Ny 10029 Timing: Fiscal Year 2002; Project Start 01-FEB-2001; Project End 31-JUL-2004 Summary: (provided by applicant): What is special about the human tongue that allows it to perform the movements that are unique to human speech and swallowing? The biomechanics of the tongue are dependent on its anatomy, and some of the most basic facts of human tongue anatomy are unknown. It is hypothesized that the human tongue contains specialized anatomy related to the movements of human speech and swallowing. Studying this anatomy will increase our understanding of tongue movements; provide a normative baseline from which to compare pathological conditions, and provide the detail required for progress in surgical procedures on the tongue, including transplantation. The human tongue presents formidable challenges for the anatomist: the small muscle groups that interweave in complex ways are technically difficult to trace; it is often difficult to identify specific muscles in histological sections; and many techniques routinely used in animal studies cannot be used on human post mortem tissue. However, based on experience studying the human larynx,

Tongue anatomy will simultaneously be studied on the gross anatomical, microscopic and molecular level using the following methods: 1) high-resolution magnetic resonance microscopy of tongue tissue to study 3D structural detail; 2) Sihler's stain, a process that renders whole tongue specimens translucent while counterstalning the nerve supply and outlines of muscle groups; 3) serial sectioning of whole tongues followed by staining to show details of muscle structure and insertion into connective tissue; 4) micro dissection of muscle fibers followed by silver and acetylcholinesterase staining to study details of muscle fiber size and shape, motor endplate types, and terminal axon branching; 5) myofibrillar ATPase, to type the muscle fibers of each muscle; 6) immunohistochemistry, to identify the myosin heavy chain (MHC) within tongue muscles; and 7) immunoelectrophoresis and immunoblotting, to confirm the immunohistochemistry. Preliminary work has supported the presence of specialized anatomy in the human tongue. Certaln muscles are significantly different in size and position when compared to other mammalian tongues. The genioglossus muscle, for example, is greatly enlarged while the inferior longitudinal is comparatively smaller. In addition, human tongue muscles have unusual internal structure: some appear to be compartmentalized into smaller groups of muscle fibers arranged in series. In the superior longitudinal muscle preliminary work suggests that these muscle compartments are surprisingly short and that the muscle fibers are interconnected in complex webs. Overall, the human tongue has the highest proportion of slow twitch muscle fibers yet reported in any mammalian tongue, and these are arranged in a gradient with the higher proportions found medially and in the tongue base. Among these slow muscle fibers are large numbers of slow tonic muscle fibers, an extremely rare type of muscle fiber with unique contractile properties. In summary, the dearth of information about the human tongue appears to offer an opportunity to increase our understanding of the special nature of speech and swallowing as well as the pathophysiology of dysphagia and dysarthria.

Project Title: THE ESOPHAGOGASTRIC JUNCTION IN HEALTH AND DISEASE Principal Investigator & Institution: Kahrilas, Peter J.; Professor of Medicine; Medicine; Northwestern University Office of Sponsored Research Chicago, Il 60611 Timing: Fiscal Year 2002; Project Start 01-APR-2001; Project End 31-MAR-2006 Summary: (Verbatim from Applicant's Abstract): Gastroesophageal reflux disease (GERD) is a common disorder, affecting millions of Americans and caused by anatomical and physiological perturbations of the esophagogastric junction (EGJ). The economic impact of GERD in the US is evident by the annual expenditure of >$4 billion for pharmaceutical treatments. Although effective, medical therapy is by nature compensatory, as opposed to potentially curative surgery. However, a problem with antireflux surgery has been unpredictable postoperative dysphagia and bloating related to a diminished ability to belch. Thus, this revised RO1 application represents a collaborative effort by a gastroenterologist (Dr Kahrilas), a surgeon (Dr Joehl), and a mechanical engineer (Dr Brasseur) to study perturbations of the EGJ imposed by GERD and by surgical treatments of GERD (Nissen fundoplication). Specific aim #1 addresses antegrade EGJ function while specific aim #2 investigates mechanisms of reflux. Antegrade EGJ function will be quantified with an "esophageal stress test" using manometry with concurrent fluoroscopy while swallowing boluses of defined viscoelastic properties. These data will be complimented by a dysphagia questionnaire. Data from controls will be compared to that of GERD patients and patients after

antireflux surgery. The underlying hypothesis of specific aim #1 is that a mathematical model of the EGJ, embedded within a "computer laboratory" and based on the best anatomical and physiological data obtainable will improve understanding and prevention of post-surgical dysphagia. Specific aim #2 is focused aboutextending our investigations into the interplay between anatomical and physiological factors in the pathophysiology of GERD. Investigational methodologies include using a barostat to create measured degrees of gastric distension and to ascertain EGJ compliance during fluoroscopy of the EGJ, using intragastric air insufflation to study the physiology of transient LES relaxations and high resolution manometry to map the geometry and mobility of the EGJ. An underlying hypothesis is that the optimal surgical management of a patient with tLESR induced reflux is different than of the patient with a patulous sphincter. The ultimate goal is to tailor the surgical management of GERD for the individual patient based on physiological studies of that patient with the hope that this will improve the efficacy and reduce the complications of antireflux surgery.

Project Title: TREATMENT OF DYSPHAGIA USING THE MENDELSOHN MANEUVER Principal Investigator & Institution: Mccullough, Gary H.; Audiology and Speech Pathology; University of Arkansas Med Scis Ltl Rock Little Rock, Ar 72205 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2005 Summary: (provided by applicant): The primary goal of the proposed investigation is to determine the effects of the Mendelsohn maneuver (voluntary prolongation of laryngeal excursion at the midpoint of the swallow) on the physiology of the swallow in individuals who have suffered a stroke and exhibit signs of pharyngeal dysphagia. The proposed study is a phase 1 investigation designed to determine whether the treatment can be safely administered to individuals post-stroke and whether the biomechanical measures of choice are reflective of treatment outcomes. This type of phase 1 study aims to provide data which is essential for the development of phase 2 and phase 3 (efficacy) studies, including the treatment dose necessary to produce physiological change. Participants who have suffered a stroke and have pharyngeal dysphagia will be divided randomly into one of two groups. Group 1 participants will receive two weeks of treatment using the Mendelsohn maneuver in conjunction with surface electromyography (SEMG) biofeedback [followed by two weeks of no treatment (BBAA)]. Group 2 participants will be placed in a no-treatment period for two weeks and will then receive two weeks of treatment using the Mendelsohn maneuver in conjunction with SEMG biofeedback (AABB). Participants will be assessed with videofluoroscopy at the initiation of the study and after each week of the study. [After the 4 weeks of participation (AABB or BBAA) are complete, all participants will be discharged from treatment and will be brought back to the clinic for a final VFS evaluation after 2 additional weeks of no-treatment.] Specific Aim 1: To determine the effect of the Mendelsohn maneuver on the biomechanics of the pharyngeal swallow (i.e., measures of swallowing extent and duration). Specific Aim 2: To determine the effect of the Mendelsohn maneuver on measures of bolus flow (i.e., pharyngeal residue and penetration/aspiration). Specific Aim 3: To determine the effect of the Mendelsohn Maneuver on an overall dysphagia severity scale (Dysphagia Oral Severity Scale DOSS). Specific Aim 4: To determine the most appropriate dose of treatment. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.6 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with dysphagia, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “dysphagia” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for dysphagia (hyperlinks lead to article summaries):

With PubMed Central, NCBI is taking the lead in preservation and maintenance of open access to electronic literature, just as NLM has done for decades with printed biomedical literature. PubMed Central aims to become a world-class library of the digital age. 5 The value of PubMed Central, in addition to its role as an archive, lies in the availability of data from diverse sources stored in a common format in a single repository. Many journals already have online publishing operations, and there is a growing tendency to publish material online only, to the exclusion of print. 6 PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

CHAPTER 2. NUTRITION AND DYSPHAGIA Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and dysphagia.
Finding Nutrition Studies on Dysphagia The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “dysphagia” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.
7 Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

Dysphagia
Electrical Muscle Stimulation to Aid Swallowing in Dysphagia Condition(s): Deglutition Disorder; Healthy Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) Purpose - Excerpt: The purpose of this study is to determine the feasibility of using extrinsic laryngeal muscle stimulation to elevate the larynx in a manner similar to that which occurs during normal swallowing. This research will also determine whether laryngeal elevation will open the upper esophageal sphincter to assist with entry of the bolus into the esophagus. This protocol includes studies in normal volunteers and patients with swallowing disorders. The outcome of this study will be relevant to future use of neuromuscular stimulation for laryngeal elevation in patients with pharyngeal dysphagia. Study Type: Observational Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00001936
•
Ultrasound and Videofluoroscopy for Diagnosing Swallowing Disorders Condition(s): Deglutition Disorder; Motor Neuron Disease Study Status: This study is currently recruiting patients. Sponsor(s): Warren G Magnuson Clinical Center (CC) Purpose - Excerpt: This study will identify clinical signs and symptoms critical for diagnosing swallowing disorders and will characterize swallowing problems in various patient populations, such as patients with Parkinson's disease, stroke, post-polio syndrome, multiple sclerosis and other conditions that cause swallowing abnormalities. Patients with swallowing difficulties who are enrolled in NIH neurology or speech pathology protocols may be eligible for this study. Participants will undergo the following procedures: 1. Oral examination-A neurologist and speech pathologist examine the patient's swallowing function. The patient is interviewed about difficulties with food intake, chewing and swallowing during meals. 2. Ultrasound examinationUltrasound creates image of areas inside the body using sound waves. With the patient in a sitting position, a 3/4-inch transducer (device for transmitting and receiving sound waves) is placed under the chin to visualize tongue movements during swallowing. 3. Modified barium swallow-While standing or sitting, the patient swallows 1/2 teaspoon of flavored barium (a radioactive substance) six times (a total of 3 teaspoons), while the tongue and pharynx (tube leading from the mouth to the esophagus) are scanned and videotaped. The barium is given in three consistencies-thin, medium and thick (pudding-like). 4. Electromyography-A small plastic strip with wires attached is placed under the patient's chin. The patient then swallows 1/2 ounce of barium three times in a row, and the movement of the chin muscles during swallowing is displayed. Patients may also be asked to swallow 5/8 cup of barium twice; once with the head tilted upward and once with the head untilted. Depending on the test results, patients may be asked to return for follow-up study and monitoring.

Comparison of Two Therapies for UES Dysphagia Condition(s): Deglutition Disorders Study Status: This study is not yet open for patient recruitment. Sponsor(s): National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Purpose - Excerpt: The aim of this research study is to determine the effectiveness of: 1) a traditional therapy regimen focusing on individual exercises for pharyngeal (throat) and laryngeal (voice box) musculature and 2) a new therapeutic exercise, the Shaker exercise. The primary objective of this 5-year project is to identify which of two therapy programs, the Shaker exercise versus traditional therapy, results in the largest number of stable, non-oral dysphagic patients who can swallow safely and return to full oral feeding after 6 weeks of intervention. The study is powered adequately so that this aim can be tested separately for head and neck cancer and stroke patients. Our primary outcome measure is return to oral feeding, i.e., 100% of nutrition and hydration by mouth.

Facilitation of Oral Bolus Propulsion Using Electropalatography in Patients with Dysphagia Condition(s): Deglutition Disorders; dysphagia Study Status: This study is completed. Sponsor(s): Warren G Magnuson Clinical Center (CC) Purpose - Excerpt: Electropalatography (EPG), a noninvasive device that provides specific visual output on tongue-palate contact, has well-established usefulness as a biofeedback tool in speech therapy. While EPG has also been shown to be capable of revealing the details of linguopalatal interactions during swallowing, its applicability in swallowing therapy has not been evaluated to date. This study will determine if EPG can facilitate bolus propulsion in patients presenting with swallowing problems of the oral phase. Seven patients with oral dysphagia will be selected to serve as subjects based on specific inclusion and exclusion criteria, and each will be custom-fitted with a pseudo-palate. Each patient will undergo four 45-minute sessions of biofeedback training with emphasis on developing systematic front-to-back anchoring of the tongue against the palate during propulsion of liquid and semisolid boluses. Ultrasound imaging will be used to determine swallow durations and identify oral deficits of swallowing before the EPG biofeedback training, and to identify any changes that may result from the training. Quantitative measurements will also be made of the swallowrelated EPG contact timing and pattern before and after training and compared for each individual subject as a function of training and bolus volume. Appropriate statistical analyses will be conducted. Study Type: Interventional Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00001718

CHAPTER 6. PATENTS ON DYSPHAGIA Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.9 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “dysphagia” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on dysphagia, we have not necessarily excluded nonmedical patents in this bibliography.
Patents on Dysphagia By performing a patent search focusing on dysphagia, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter.

Dysphagia cup Inventor(s): Stevens; Barry A. (1039 Madison Ave. North, Bainbridge Island, WA 98110) Assignee(s): None Reported Patent Number: 5,323,928 Date filed: September 16, 1992 Abstract: A drinking cup 10 for assisting swallowing has a hollow container portion 12 including a base 18 and an upwardly extending, elliptically-shaped sidewall 20. The sidewall defines an elliptical aperture 32 at its apex. The inner surface 26 of the sidewall defines an ellipse from a cross-sectional perspective at substantially all elevations between the aperture and a point proximate to the base, each cross section being taken along a plane disposed parallel to a plane defined by the aperture. The elliptical aperture is sized to accommodate a person's nasal bridge during drinking such that substantial backwards angulation of the head is not required. The cup includes a handle 16 disposed 90.degree. out from the major axis of the elliptical aperture. People with dysphagia and/or arthritis are expected to benefit especially from the features of the present invention. Excerpt(s): The present invention relates to drinking cups, and more particularly, to drinking cups for people suffering from dysphagia or who have problems holding the handle of a conventional cup. Drinking cups are generally comprised of a container portion for holding the desired liquid and a handle for the person using the cup to hold on to. Generally, in order to be able to use a conventional drinking cup, a person must angulate his or her head backwards to avoid spilling of the fluid contents of the cup. This spilling occurs partly because conventional cups, in almost all cases, have a cylindrically-shaped container which does not provide sufficient clearance for the user's nose. In order to tip the cup to a degree sufficient to allow fluid, particularly thick, viscous fluids, to flow toward the mouth, the user is required to angulate his or her head while drinking. People suffering from dysphagia, a condition associated with difficulty in swallowing, often have trouble swallowing when the head is tilted due to a tendency to aspirate fluid into the lungs. This is sometimes a condition associated with having a stroke, head injury, or other neurological disorders and aging. Additionally, people so afflicted often encounter problems with liquid spillage when drinking from conventional cups due to the large radius of the rim. It is known that swallowing in people suffering from dysphagia may be enhanced if the head is not angulated rearwardly while drinking. In an attempt to take advantage of this, conventional "nosecups" have been designed which include a container part whose inner wall is circular in shape, but which is provided with a cut-out on the rim to accommodate the nose of the user, so that drinking can be accomplished while the user's head remains substantially vertical. However, such cups have an unusual appearance, which some users may find undesirable and thus avoid using. Additionally, such conventional "nose-cups" have cylindrical inner walls which do not facilitate controlled fluid flow, tending to lead to fluid spillage or the inability to empty cup of thicker fluids.

Gelatinous food product and process for preparing the same Inventor(s): Emoto; Mitsuo (Otsu, JP) Assignee(s): Otsuka Foods Co., Ltd. (osaka, Jp) Patent Number: 6,458,395 Date filed: July 7, 2000 Abstract: The present invention provide a gelatinous food product for supplying balanced nutrition, which is a gel of an emulsified mixture comprising 10 to 50 wt. % of total solid content on a dry weight basis and 50 to 90 wt. % of water, the solid content contains 30 to 90 wt. % of saccharide, 5 to 40 wt. % of lipid, 2 to 60 wt. % of protein, 0.2 to 5 wt. % of organic acid, 0.2 to 5 wt. % of organic acid salt, 0.2 to 5 wt. % of emulsifying agent and 0.2 to 5 wt. % of gelling agent, the food product having a pH of 3.3 to 4 and being a composite of an isoelectric gel of the protein and a heat-soluble gel formed with the gelling agent. The invention also provides a process for preparing the food product. The gelatinous food product of the invention is particularly suitable for nutrition of patients with dysphagia, since it comprises various nutrients in suitable proportions and has good eating qualities, for instance, ease of swallowing even by patients with dysphagia, owing to the soft jelly form. Excerpt(s): The present invention relates to gelatinous food products for supplying balanced nutrition, particularly the gelatinous food products which contain all the essential nutrients, and which have a refreshing taste because of their pH of 3.3 to 4, and which is a composite of a gel formed with a gelling agent and an isoelectric gel of the protein, the composite producing good eating qualities, for instance, ease of swallowing owing to the soft gel form. Conventionally, jellies made by setting beverages with agars or gelatins and gelatinous foods such as puddings, yogurts and aspics are known as foods for supplying water and nutrients to patients suffering from dysphagia (swallowing difficulty), typically elderly patients and patients with cerebrovascular diseases. If a substantially nonviscous liquid such as water or tea is carelessly given to patients with dysphagia, the liquid cannot be swallowed properly and may enter the trachea, increasing the risk of pneumonia, or threatening the life in extreme cases. The jellies or gelatinous foods are provided to the patients in order to avoid such risks. Foods for patients with dysphagia are required to have the following properties. First, they should contain all the essential nutrients in suitable proportions for giving the patients sufficient nutrition. Further, they should have appropriate firmness and consistency that enable easy swallowing or easy chewing; should be cohesive in the mouth without separation; and should pass through the throat smoothly when swallowed.

Dysphagia
Abstract: This invention is directed to a simple, non-invasive method and device for treating dysphagia and artificially promoting swallowing by electrical stimulus. In the present invention, a plurality of electrodes are selectively placed in electrical contact with tissue of a pharyngeal region of patient and a series of electrical pulses in electrical contact with each of the plurality of electrodes with a generator. The generator includes a pulse rate modulator for generating each of the electrical pulses having a frequency generally fixed at 80 hertz, a pulse width modulator for generating each pulse of the series of electrical pulses at a duration generally fixed at 300 microseconds, and a governor for regulating the electrical pulses such that at least one of current so as not to exceed 4.4 milliamps RMS or power so as not to exceed 9.6 MW RMS. The electrical pulses selectively stimulate muscles located proximate to the selectively placed electrodes to initiate swallowing. Excerpt(s): This invention relates to a method and device for effectively treating dysphagia. In particular, the present invention relates to a method and device for treating dysphagia by providing electrical stimulation to the pharyngeal region of an associated animal. Dysphagia is the inability to swallow or difficulty in swallowing and may be caused by stroke, neurodegenerative diseases, or respiratory disorders. Swallowing is a complicated action which is usually initiated voluntarily but always completed reflexively, whereby food is moved from the mouth through the pharynx and esophagus to the stomach. The act of swallowing occurs in three stages and requires the integrated action of the respiratory center and motor functions of multiple cranial nerves, and the coordination of the autonomic system within the esophagus. In the first stage, food is placed on the surface of the tongue. The tip of the tongue is placed against the hard palate. Elevation of the larynx and backward movement of the tongue forces the food through the isthmus of the fauces in the pharynx. In the second stage, the food passes through the pharynx. This involves constriction of the walls of the pharynx, backward bending of the epiglottis, and an upward and forward movement of the larynx and trachea. Food is kept from entering the nasal cavity by elevation of the soft palate and from entering the larynx by closure of the glottis and backward inclination of the epiglottis. During this stage, respiratory movements are inhibited by reflex. In the third stage, food moves down the esophagus and into the stomach. This movement is accomplished by momentum from the second stage, peristaltic contractions, and gravity. Although the main function of swallowing is the propulsion of food from the mouth into the stomach, swallowing also serves as a protective reflex for the upper respiratory tract by removing particles trapped in the nasopharynx and oropharynx, returning materials refluxed from the stomach into the pharynx, or removing particles propelled from the upper respiratory tract into the pharynx. Therefore, the absence of adequate swallowing reflex greatly increases the chance of pulmonary aspiration. Web site: http://www.delphion.com/details?pn=US05725564__

Method and apparatus for treating oropharyngeal disorders with electrical stimulation Inventor(s): Asmar; Marie (Richmond Heights, OH), Beytas; Erol M. (Beachwood, OH), Christian; Michael O. (Beachwood, OH), Freed; Leonard A. (Kailua, HI), Freed; Marcy L. (Pepper Pike, OH), Kotton; Bernard (Beachwood, OH), Tucker; Howard (Cleveland Heights, OH) Assignee(s): Esd Limited Liability Company (beachwood, Oh) Patent Number: 5,891,185 Date filed: November 10, 1997 Abstract: A simple, non-invasive device and method for treating oropharyngeal disorders provides electrical stimulation to the pharyngeal region of a patient. Oropharyngeal disorders may cause an inability to swallow or difficulty in swallowing. The method and device provide an effective and non-invasive treatment for these disorders which is substantially more effective than traditional treatment methods, such as thermal stimulation. The method and device also effectively treat worst-case dysphagia (the inability to swallow) resulting from neurodegeneration and strokes. The device, an electrical pharyngeal neuromuscular stimulator, includes one or more pulse generators for generating a series of electrical pulses and a processor coupled to the pulse generators for controlling their operation. A switching network is also coupled to the pulse generators. The switching network directs series of electrical pulses respectively generated by the pulse generators to an electrode array positioned on the tissue of a patient's pharyngeal region. The processor controls the switching operation of the switching network by determining which electrode in the electrode array receives the series of pulses generated by the respective pulse generators. The electrode array also generates electrical feedback signals in response to the neuromuscular stimulation of the patient. The electrical feedback signals are provided to the processor via the switching network. The processor generates and stores test data and modifies the operation control signals and switching control signals in response to the electrical feedback signals. Excerpt(s): This invention relates to a method and apparatus for effectively treating oropharyngeal disorders. In particular, the present invention relates to a method and apparatus for treating oropharyngeal disorders by providing electrical stimulation to the pharyngeal region of an associated animal. A symptomatic and symptomatic oropharyngeal disorders can lead to an inability to swallow or difficulty in swallowing. These disorders may be caused, for example, by stroke, neurodegenerative diseases, brain tumors or respiratory disorders.

Dysphagia
Abstract: Dysphagia, or difficulty in swallowing, can cause choking, aspiration of food or liquid into the lungs, incomplete administration of medication, and discomfort to the victims. A method is provided for evaluating the severity of Dysphagia. The method comprises providing at least two sets of orally ingestible materials, each set of orally ingestible material comprising at least two compositions of like materials differing significantly in one property selected from the group consisting of viscosity, adhesiveness, cohesiveness and yield force. A patient ingests a first one of the at least two compositions from a first set of the at least two sets, examining the patients for a dysphagic response to the ingestion of the first one of the at least two compositions, and noting any dysphagic responses. Steps b), c) and d) are repeated for another set of orally ingestible materials which another set of the at least two sets of orally ingestible materials characterizes a property that is different from a property selected from the group consisting of viscosity, adhesiveness, cohesiveness and yield force characterized by the first one of the at least two compositions from a first set of the at least two sets of orally ingestible material. Excerpt(s): Dysphagia is a condition or symptom defined as a difficulty in swallowing. The present invention relates to a method for the standardized measurement of the quality or degree of dysphagia and a kit used for that method. Dysphagia, or difficulty in swallowing, is a condition or symptom which can be caused by many different conditions, injuries or diseases. Dysphagia can cause choking, aspiration of food or liquid into the lungs, incomplete administration of medication, and discomfort to the victims. These factors can at least discomfort a patient, but may also interfere with or complicate conventional treatment of patients. Among the many contributions to or causes of dysphagia are head injuries, Parkinsonism, Alzheimer's disease, muscular dystrophy, cerebral palsy, cancer, medication side effects, advanced HIV infections, gastrointestinal disorders, and brain tumors. It has been estimated that more than 10,000 patients a year choke to death as a result of dysphagia. Dysphagia is a well-recognized condition and has been studied and addressed by doctors and nutritionists (Robertson, Helen M. And Pattillo, Margaret S., Journal of the Canadian Dietetic Association, Vol. 54, No. 4, Winter 1993). Such studies have noted that the condition is affected by the temperature, pH, viscosity, volume, size and shape of particulate matter in the ingested sample, and that these conditions can affect the likelihood of a bolus passing safely through the swallowing process.

suffering from dysphagia. Several beverages currently exist which aid in replacing fluids lost to exertion or illness. For example, GATORADE.RTM. is a well known beverage which serves to replace fluids and necessary minerals in athletes. PEDIALYTE.RTM. is a well known beverage which serves essentially the same purpose for infants and small children. None of the isotonic beverages currently on the market address the problem of dysphagia, which is a difficulty in swallowing. Although dysphagia can have many different possible medical-causes, a difficulty in swallowing is common to them all. People who have this difficulty also have a need for replenishing fluids and electrolytes. It has been found that people with this affliction can more easily swallow liquids which have been thickened. Unfortunately, no prethickened isotonic beverage is currently available. Consequently, a need still exists for such a prethickened, isotonic beverage. Web site: http://www.delphion.com/details?pn=US06033713__

Aspiration screening process for assessing need for modified barium swallow study Inventor(s): Addington, W. Robert; (Indialantic, FL), Miller, Stuart P.; (Melbourne Beach, FL), Ockey, Roben R.; (San Antonio, TX), Stephens, Robert E.; (Parkville, MO) Correspondence: Charles E. Wands, Esq; Allen, Dyer, Doppelt, Milbrath, Gilchrist, P.A.; P.O. Box 3791; Orlando; FL; 32802-3791; US Patent Application Number: 20010003143 Date filed: December 12, 2000 Abstract: Whether a (stroke) patient is at risk for oral or pharyngeal dysphagia is determined by conducting a cough-based screening process for clinically evaluating the patient's swallow. The cough-based screening methodology is able to identify those patients who require a modified barium swallow test in order to rule out aspiration, and which patients do not need a modified barium swallow test. In accordance with the process the patient attempts to cough voluntarily. If the patient is unable to cough voluntarily, the patient is required to inhale an aerosol that stimulates a sensory innervation of the patient's larynx, thereby causing the patient to cough. The resulting cough is graded to determine whether the patient is at risk to a prescribed physiological condition, in particular pneumonia. The cough tests are supplemented by monitoring the ability of the patient to hold water in the patient's mouth for a prescribed period of time. If the patient is able to hold a prescribed volume of water in the patient's mouth for the prescribed period of time, the patient is permitted to be given a modified barium swallow test. If the patient is unable to hold a prescribed volume of water in the patient's mouth for the prescribed period of time, the patient is not permitted to be given a modified barium swallow test.

Dysphagia
Excerpt(s): The present invention relates in general to the field of speech pathology, and is particularly directed to a process for determining whether a patient is at risk for oral or pharyngeal dysphagia, by means of a cough-based screening process for clinically evaluating the patient's swallow. In order to clinically detect those patients who are at risk for aspiration, speech pathologists currently employ a standard procedure for evaluating a patient's swallow. A normal human swallow can be separated into four phases: 1)-oral preparation, 2)-the oral phase, 3)-the pharyngeal phase, and 4)-the esophageal phase. Patients who have suffered a stroke, traumatic brain injury or neuromuscular disorder (such as MS or ALS) have an increased risk of aspiration, and may have difficulty with either the oral phase, the pharyngeal phase or both, secondary to neurologic deficits. Poor tongue movement in chewing or in the swallow can cause food to fall into the pharynx and into the open airway before the completion of the oral phase. A delay in triggering the pharyngeal swallowing reflex can result in food falling into the airway during the delay when the airway is open. Reduced peristalsis in the pharynx, whether unilateral or bilateral, will cause residue in the pharynx after the swallow that can fall or be inhaled into the airway. Laryngeal or cricopharyngeal dysfunction can lead to aspiration because of decreased airway protection during the swallow. An abnormal human swallow is termed dysphagia. The oropharyngeal physiology involved in a normal swallow is very complicated, and many different neurological disturbances can disrupt normal swallowing and can cause aspiration of food material, liquid or solid, into the lungs, leading to increased morbidity in hospitalized patients and possible pneumonia. See, for example, the article by Jeri Logemann, entitled: "Swallowing Physiology and Pathophysiology," Otolaryngologic Clinics of North America, Vol. 21, No. 4, November, 1988, and the article by L. Kaha et. al., entitled: "Medical Complications During Stroke Rehabilitation, Stroke Vol. 26, No. 6, June 1995. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Bread equivalents and methods of making the same Inventor(s): Meister, Jeff; (Plymouth, MN) Correspondence: Thomas Hoxie; Novartis, Corporate Intellectual Property; One Health Plaza 430/2; East Hanover; NJ; 07936-1080; US Patent Application Number: 20030228408 Date filed: June 2, 2003 Abstract: A bread equivalent suitable for patients suffering from difficult in chewing or swallowing includes a starch-base and a gelling agent blended to form a dry mix and mixed with a liquid vehicle, such as water. The bread equivalent has properties that are similar to real bread. For example, the bread can be sliced and topped with spreadable foods like butter, margarine and the like. The bread equivalent lacks the glutenous nature of bread making it amenable for ingestion by patients having dysphagia. Excerpt(s): The present invention relates to food compositions that have attributes similar to bread yet suitable for ingestion by patients who have difficulty swallowing or chewing. Bread has been a staple in the diet of man for centuries providing essential nutrients such as protein, carbohydrates as well as vitamins and minerals. For most people, bread is a major component of at least one meal a day. However, for some individuals, bread can be rarely enjoyed because they have dysphagia, or difficulty in chewing and/or swallowing. This is because the gluten in bread makes the bread too elastic. While elasticity is good for rising and making bread higher, it makes bread
Patents 107
nearly impossible for dysphagic patients to chew the bread. Because of bread's nutritional value, healthcare providers have recognized the importance of bread in a patient's diet. In order to make bread accessible to dysphagic patients, bread is typically soaked in water or milk and pureed resulting in a mushy consistency that resembles mashed potatoes. Instead of eating the bread in discrete pieces, the mashed bread is spoon-fed to the patient. Not only is this method of eating bread not appetizing but also ineffective in rehabilitating the patients to regain muscle tone in their jaws.

Gelled nutritional composition and process Inventor(s): DeWille, Normanella T.; (Columbus, OH), Liebrecht, Jeffery W.; (Columbus, OH), Mazer, Terrence B.; (Reynoldsburg, OH) Correspondence: Ross Products Division OF Abbott Laboratories; Department 108140ds/1; 625 Cleveland Avenue; Columbus; OH; 43215-1724; US Patent Application Number: 20030091613 Date filed: November 8, 2001 Abstract: A nutritional supplement in the form of a gelled nutritional composition. The composition contains gelled whey protein, a carbohydrate source, minerals, and vitamins. The composition may have a viscosity greater than about 2000 cp, more typically greater than about 5000 cp and an energy density greater than about 600 kcal/liter. The composition is suitable for dysphagia patients, children, and athletes. Excerpt(s): This invention relates to a gelled nutritional composition which may provide a nutritional supplement; for example for dysphagia patients and children. The invention also relates to a process for producing the gelled nutritional composition and to a method for providing nutrition to a dysphagic patient or post operatively to a patient recovering from surgery. Many people do not take in sufficient nutrients for a nutritionally complete diet. In order to assist these people, nutritional supplements have been developed. Nutritional supplements are not intended to provide all the nutrients necessary for a nutritionally complete diet; instead they are intended to supplement the diet such that it becomes more nutritionally complete. There are many targets for nutritional supplements; for example children, the elderly and patients suffering from dysphagia. Dysphagia, refers to difficulty in swallowing and occurs in all age groups. It is especially prevalent amongst the elderly. Typical symptoms include drooling, a feeling that food is sticking in the throat, discomfort in the chest and throat, a feeling of a lump in the throat, and coughing or choking caused by food not passing easily to the stomach and being sucked into the lungs.

Dysphagia
Method and apparatus for treating poor laryngeal-elevation disorder with sequentialhigh voltage electrical stimulation Inventor(s): Geater, Alan; (Hatyai, TH), Leelamanit, Vitoon; (Hatyai, TH), Limsakul, Chusak; (Hatyai, TH) Correspondence: Reed Smith Hazel & Thomas Llp; Suite 1400; 3110 Fairview Park Drive; Falls Church; VA; 22042; US Patent Application Number: 20020133194 Date filed: January 29, 2001 Abstract: The sequential stimulator for the treatment of dysphagic patients incorporates a unit which is capable of detecting a swallowing signal from the glossal or temporalis surface electromyography (SEMG). When a swallowing signal is recognized, a trigger signal is sent to the stimulation generation unit to release high voltage stimuli sequentially to the suprahyoid muscles or the masseter muscles and the pharyngeal muscles in order to assist in the elevation of the larynx. This enables the pharyngeal lumen to open more widely so that food can pass through the patient's pharynx and into the oesophagus more easily during swallowing. Thus the sequential stimulator is a device for assisting swallowing in patients with dysphagia due to a variety of causes, for instance, brain injury, cerebrovascular accident, injury of the cervical nerves, muscles weakness, or old age. The stimulator is operative only when the patient attempts to swallow and provides a physiologic stimulus and provides a means of immediate relief of the swallowing difficulty. The device is also useful for physical therapy whereby the muscles under the chin, the masseter muscles and the pharyngeal muscles can be reeducated to contract in the normal coordinated sequence. Excerpt(s): The present invention relates generally to a method and an apparatus for treating poor laryngeal-elevation disorder with sequential-high voltage electrical stimulation. Phase 1: is the oral phase, during which food in the oral cavity is masticated and mixed. Phase 2: is the pharyngeal phase, during which the masticated and mixed food bolus is propelled from the oral cavity into the pharyngeal lumen and thence into the upper oesophagus. The second phase of swallowing involves the use of the glossal muscles and the pharyngeal muscles (suprahyoid and thyrohyoid) and a lowering of the base of the tongue. The tongue muscles then propel food bolus from the oral cavity into the pharyngeal lumen. At this stage, the muscles of the pharynx contract in sequence, raising elevating the larynx and moving it forward in order to open the pharyngeal lumen and the upper oesophageal sphincter so that the bolus can pass readily into the upper oesophagus.

Standardized compositions which facilitate swallowing in dysphagic subjects Inventor(s): Robbins, Jo Anne; (Madison, WI) Correspondence: Dewitt Ross & Stevens S.C.; 8000 Excelsior DR; Suite 401; Madison; WI; 53717-1914; US Patent Application Number: 20030044351 Date filed: August 26, 2002 Abstract: Disclosed are kits containing two or more viscosity-standardized, edible solutions for evaluating human subjects for dysphagia. Also disclosed are corresponding methods of using the kits for diagnosing dysphagia and for radiographic imaging of the oropharynx. Excerpt(s): This is a continuation-in-part of co-pending application Ser. No. 09/442,704, filed Nov. 18, 1999, which claims priority to provisional application Serial No. 60/151,213, filed Aug. 27, 1999, the contents of both of which are incorporated herein by reference. The invention is directed to standardized, viscosity-modified, edible formulations for use with dysphagic patients and methods to gauge the viscosity of modified foods using the standardized formulations. The formulations described herein can also be combined with a radio-opaque agent to facilitate improved dynamic fluoroscopic imaging of the oropharynx, hypopharynx, etc. The oropharyngeal physiology involved in a normal swallow is an exceedingly complex series of coordinated actions. A host of very different medical conditions, both physical and neurological in nature, can alter normal swallowing. For example, patients suffering stroke, Alzheimer's disease, amyotrophic lateral sclerosis, or traumatic brain injury can exhibit abnormal swallowing. In many instances, the abnormal swallow can and does cause aspiration of food material, both liquids and solids, into the lungs. This is especially prevalent (and life-threatening) in bed-ridden patients. Aspiration of foreign material into the airways leads to increased morbidity in hospitalized patients and can lead to pneumonia. Abnormalities in the human swallow, whether or not the condition results in aspiration of foods, is called dysphagia. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

[email protected]. PRICE: $56.95. ISBN: 156593749X. Summary: This textbook focuses on the principles of assessment and treatment planning for patients with dysphagia (swallowing dysfunction). The first chapter covers normative aspects of swallowing and head and neck examination for a patient with dysphagia. Chapter 2 follows with a description of dysphagia impairment, particularly in patients recovering from oral, oropharyngeal, or laryngeal cancer. This is followed by a chapter on the implications of various neurogenic disorders for swallow function, and with recommendations for the timing of swallow studies in these patient populations. Chapters 4 through 10 deal with dysphagia assessment. Four chapters are devoted to radiographic assessment of swallowing, which reflects the importance of the dynamic swallow study as a diagnostic tool. Chapter 11 focuses on the treatment plan, illustrating how assessment information is formulated into a treatment plan, and how such a plan relates to a team approach. This chapter also briefly covers the major categories of treatment which may result. Since a nutritional consultation is frequently recommended following the dysphagia team evaluation, a chapter is devoted to dietary assessment. Chapter 13 is devoted to pediatric assessment, and helps readers adapt the standard assessment protocol to infants and young children. The book is accompanied by a CD-ROM disk, which provides examples of fluoroscopic studies of dynamic swallows. The CD-ROM includes studies from 10 normal adults and 9 dysphagic adults. For most of the normal subjects, 1 cc, 3 cc, paste, and self-select boluses are presented. In addition, three of the normal studies include subjects producing the vowels A, I, and U. Each normal study includes the authors' measurements for each swallow, so that any measures users make can be compared to the authors'. Each chapter includes black and white photographs or radiographs, charts, and extensive references; a subject index concludes the volume.

Recognition and Management of Pediatric Swallowing Disorders Source: in Kleinmann, R.E., ed. Pediatric Nutrition Handbook. 4th ed. Elk Grove Village, IL: American Academy of Pediatrics. 1998. p. 107-122. Contact: Available from American Academy of Pediatrics. P.O. Box 927, 141 Northwest Point Boulevard, Elk Grove Village, IL 60009-0927. (800) 433-9016. PRICE: $47.95 (members) plus $6.25 shipping and handling; $52.95 for nonmembers; plus $8.95 shipping and handling. ISBN: 1581100051. Summary: Assessment of nutritional status and providing dietary advice and nutritional support are important and increasingly prominent components of the practice of those who provide health care for infants, children, and adolescents. This chapter on the recognition and management of pediatric swallowing disorders is from a handbook that serves as a ready desk reference on the nutritional requirements and impact of nutritional status on the health of infants, children, and adolescents. Topics include common conditions associated with dysphagia (swallowing disorders), the consequences of dysphagia, recognition of pediatric dysphagia, clinical evaluation, the instrumental and radiographic (x ray) evaluation of dysphagia (pharyngeal manometry, electromyography), treatment options, feeding infants with cleft lip or cleft palate, and the efficacy of rehabilitative dysphagia management. The authors stress that because pediatric swallowing dysfunction may result in substantial morbidity, timely recognition and treatment is essential. Anatomic defects of the oropharynx, larynx, or esophagus, as well as disease processes that alter motor or sensory function, may lead to swallowing abnormalities. Pediatric dysphagia may result in unsuccessful feeding leading to malnutrition; behavioral feeding problems, including refusal of food, expulsion of food, and disruptive mealtime behaviors; drooling; and respiratory compromise. Treatment options can include positioning, oral sensory normalization, modification of food consistency, adaptive feeding devices, and oral feeding exercises. 2 tables. 47 references.

PRICE: $229.00 plus shipping and handling. ISBN: 0721689736. Summary: Occasional esophageal complaints are common and usually are not harbingers of disease. However, frequent or persistent dysphagia (swallowing difficulty), odynophagia (painful swallowing), or heartburn immediately suggests an esophageal problem that necessitates investigation and treatment. This chapter on dysphagia, odynophagia, heartburn, and other esophageal symptoms is from a comprehensive and authoritative textbook that covers disorders of the gastrointestinal tract, biliary tree, pancreas, and liver, as well as the related topics of nutrition and peritoneal disorders. Topics include the mechanisms and classification of dysphagia, odynophagia, the symptoms and mechanisms of heartburn, globus sensation, chest pain, and respiratory, ear, nose and throat, and cardiac symptoms of esophageal problems. The author stresses that in particular, gastroesophageal reflux disease (GERD) may manifest with atypical complaints and should not be missed, because it is readily treatable. The chapter includes a mini-outline with page citations, full-color illustrations, and extensive references. 1 figure. 5 tables. 73 references.

misdirection of the bolus to the airway or nasopharynx. This chapter on OPD and associated disorders is from a lengthy textbook that brings practitioners up to date on the complexities of gastroenterology practice, focusing on the essentials of patient care. Topics include anatomy, the physiology of swallowing, the pathophysiology of OPD, clinical features of OPD, diagnostic evaluation of the condition, and treatment options, including rehabilitation and retraining, cricopharyngeal dilation and myotomy, and the correction of anatomic abnormalities. The authors stress that the evaluation and treatment of OPD requires a multidisciplinary approach. The initial goals in the treatment of OPD are palliation of dysphagia and prevention of aspiration; these are most successful only after a correct diagnosis is made. 6 figures. 5 tables. 37 references. •

[email protected]. Website: www.singpub.com. PRICE: $56.95 plus shipping and handling. ISBN: 156593749X. Summary: This chapter is from a textbook that focuses on the principles of assessment and treatment planning for patients with dysphagia (swallowing dysfunction). The chapter provides a description of dysphagia impairment, particularly in patients recovering from oral, oropharyngeal, or laryngeal cancer. These patients are the most common head and neck population to experience dysphagia, but the concepts involved in understanding the etiology of dysphagia in this group can be generalized to other patient populations. In patients with head and neck cancer, interference with normal swallowing can result from the growth of the tumor that invades structures and impairs functioning or from the obstructive effects of the tumor itself. Surgery to excise the tumor with a margin of normal tissue results in a defect and loss of structures, which typically also produces dysphagia. When radiation therapy is added to the regimen postoperatively, dysphagia may worsen secondary to xerostomia (dry mouth) and fibrosis of soft tissues in the field of radiation exposure. The author stresses that all patients undergoing surgery for head and neck cancers involving the oral cavity, pharynx, and larynx should be considered at risk for dysphagia in the postoperative period. Specific structures discussed include the oral sphincter, anterior floor of the mouth, tongue, mandible, palate, pharynx, larynx, and base of skull. The author concludes that the defects described in the chapter are often combined or only partial. Other factors, including the overall medical condition, social situation, and support system, will also likely impact the patient's ability to achieve adequate safe oral intake to maintain nutritional requirements. 12 references.

Summary: This chapter on dysphagia in adults is from a textbook that is designed to help new professionals with a transition to clinical practice in speech language pathology. Sometimes dysphagia (difficult swallowing) occurs at the same time as a
122
Dysphagia
communication disorder, and sometimes it does not. Regardless, assessment and treatment falls within the practice of speech language pathologists. The author emphasizes that the speech language pathologist functions as part of a dysphagia patient care team, which typically includes a radiologist, a pulmonary physician, a gastroenterologist, a nutritionist, otolaryngologists, and a nurse. The author reviews the different types of dysphagia, then considers assessment issues; the evaluation of neurogenic dysphagia, including Guillain Barre syndrome, multiple sclerosis, amyotrophic lateral sclerosis or ALS, Parkinson disease, and stroke; the evaluation of mechanical dysphagia, including that due to acute inflammations, macroglossia (large tongue), pharyngeal diverticulum, cancer, and tracheostoma tube; and assessment tests, including ultrasound, the Blue Dye Test, fiberoptic endoscopic examination of swallowing (FEES), videofluoroscopy, cervical auscultation, electromyography (EMG), electroglottography (EGG), pharyngeal manometry, esophageal stage studies, and protocols for dysphagia assessment. The latter section of the chapter covers therapy, including diet, oral and non-oral feedings, and specific treatment procedures such as postural techniques, sensory awareness, effortful swallow, the Mendelsohn maneuver, the supraglottic swallow, and the super supraglottic swallow. 10 tables. •

Summary: This chapter on the approach to patients with dysphagia (swallowing difficulty) or odynophagia (painful swallowing) is from a lengthy, two-volume textbook that integrates the various demands of science, technology, expanding information, good judgment, and common sense into the diagnosis and management of gastrointestinal patients. Topics include symptom definitions, mechanisms responsible for symptom production, differential diagnoses, and recommended approaches to patients with dysphagia and to those with odynophagia. Patients with oropharyngeal dysphagia typically describe food lodging or sticking in the back of the throat or cervical esophageal region. Hesitation with swallowing, frequent and repeated attempts at swallowing, and throat clearing may accompany the dysphagia. Pain during the oropharyngeal phase of swallowing has been attributed to a variety of processes, particularly malignancies, foreign body ingestion, and mucosal inflammation and ulceration. 4 figures. 4 tables. 162 references.

PRICE: $39.95 plus shipping and handling. ISBN: 0939957582. Summary: This chapter, from a guide to the management of patients with amyotrophic lateral sclerosis (ALS), describes the role of the speech-language pathologist, particularly in treating the dysphagia and dysarthria common to ALS. Concerns specific to the speech-language pathologists (SLP) are the effects of the disease on the patient's oral

123
mechanism, communicative abilities, and deglutition. Furthermore, the SLP address the familial and psychosocial issues surrounding speech and swallowing compromise. The author presents a model for the diagnosis and treatment of the ALS patient, dealing with the issues within the scope of practice of the SLP, based on the author's clinical experience. The author notes that the manifestations of ALS (oral mechanism compromise, communicative disorder, dysphagia, and family issues) are more dramatic in clinical presentation and become more crucial when confronted with a patient presenting with bulbar symptomatology either initially or progressively. Paradoxically, it is the progressively bulbar nature of ALS that has fostered innovative and adaptive diagnostic and therapeutic methods, resulting in improved quality of life throughout the remaining life span. The author emphasizes the need for therapy to adapt to the progressive nature of the disease, in order to achieve the best possible quality of life for the patient. 9 references. (AA-M). •

Summary: This chapter, from a medical textbook on dysphagia, describes medical, behavioral and development issues related to pediatric dysphagia. Topics include ontogeny; pathology, including the developmental manifestations of dysphagia disability, and the causes and consequences of feeding disorders; the pediatric clinical evaluation, including the use of imaging techniques such as videofluoroscopy and ultrasonography; and clinical management of the child with dysphagia, including procedures for improving feeding skills and swallowing. The author focuses on the relationship between feeding behaviors and parent-child interactions, psychosocial development, acquisition of developing oral motor skills, nutrition, and respiratory health. Early and comprehensive management of dysphagia is important to minimize the wide-ranging primary and secondary medical and developmental consequences that may occur. These consequences can include failure to thrive, pulmonary disorders, increased risk for choking, prolonged and uncomfortable mealtime experiences, stressors in the parent-child relationship, failure to advance eating skills, and drooling. The chapter concludes with three illustrative case studies. 4 tables. 45 references.

Search Engines Medical news is also available in the news sections of commercial Internet search engines. See the health news page at Yahoo (http://dir.yahoo.com/Health/News_and_Media/), or you can use this Web site’s general news search page at http://news.yahoo.com/. Type in “dysphagia” (or synonyms). If you know the name of a company that is relevant to dysphagia, you can go to any stock trading Web site (such as http://www.etrade.com/) and search for the company name there. News items across various news sources are reported on indicated hyperlinks. Google offers a similar service at http://news.google.com/. BBC Covering news from a more European perspective, the British Broadcasting Corporation (BBC) allows the public free access to their news archive located at http://www.bbc.co.uk/. Search by “dysphagia” (or synonyms).
Newsletter Articles Use the Combined Health Information Database, and limit your search criteria to “newsletter articles.” Again, you will need to use the “Detailed Search” option. Go directly to the following hyperlink: http://chid.nih.gov/detail/detail.html. Go to the bottom of the search page where “You may refine your search by.” Select the dates and language that you prefer. For the format option, select “Newsletter Article.” Type “dysphagia” (or synonyms) into the “For these words:” box. You should check back periodically with this database as it is updated every three months. The following is a typical result when searching for newsletter articles on dysphagia: •
Pediatric Dysphagia: Practice and Challenges Source: ASHA Leader. 6(11): 4-7. June 12, 2001. Contact: Available from American Speech-Language-Hearing Association (ASHA). Product Sales, 10801 Rockville Pike, Rockville, MD 20852. (888) 498-6699. TTY (301) 8970157. Website: www.asha.org. Summary: This article reviews the challenges inherent in caring for children with dysphagia (swallowing disorders). The author notes that speech language pathologists (SLPs) are being asked to diagnose and treat an increasing number of swallowing disorders. The incidence of children with dysphagia is increasing because of improved technology, which has saved the lives of many children with life threatening conditions. The inclusive practice model and the Individuals with Disabilities Education Act (IDEA) have resulted in the increasing involvement of SLPs providing services to individuals with feeding and swallowing disorders in the educational setting. The author discusses the identification of the infant or child with dysphagia, the diagnosis of swallowing disorders, the management of feeding and swallowing disorders, and the role of the SLP
132
Dysphagia
in a multidisciplinary team approach to these children. Treatment of swallowing disorders usually involves the use of compensatory techniques to help the child swallow safely and habilitative techniques (such as oral motor exercises) that are designed to change swallowing physiology. Other considerations must be made for habilitative or rehabilitative techniques in children, including level of alertness and interactiveness, age and cognitive ability, receptive language skills, and capacity for compliance. 22 references. •
Dysphagia: When Swallowing Becomes Difficult, See Your Doctor Source: Mayo Clinic Health Letter. 16(8): 4-5. August 1998. Contact: Available from Mayo Clinic Health Letter. Subscription Services, P.O. Box 53889, Boulder, CO 80322-3889. (800) 333-9037 or (303) 604-1465. Summary: This newsletter article describes dysphagia, or swallowing difficulties. The article outlines the mechanics of swallowing and describes two categories of swallowing disorders: oropharyngeal dysphasia, when a stroke or neuromuscular disorder leaves throat muscles weakened; and esophageal dysphagia, which refers to the sensation of food sticking or getting hung up in the base of the throat or chest. Esophageal dysphagia can be caused by peptic stricture (narrowing of the lower esophagus), tumors, certain muscle problems, diverticulum, and complications of radiation therapy for cancer treatment. The article notes the diagnostic tests that may be used to confirm swallowing problems, including barium x-ray, endoscopy, and manometry. The author reminds readers that treatment options for dysphagia depend on the cause of the disorder, but can include diet therapy, physical therapy, esophageal dilatation, drug therapy, and surgery. One sidebar summarizes the questions that patients should think about before going to see their physician; the answers to these questions will help the physician come to an accurate diagnosis. 1 figure.
Academic Periodicals covering Dysphagia Numerous periodicals are currently indexed within the National Library of Medicine’s PubMed database that are known to publish articles relating to dysphagia.

CHAPTER 10. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for dysphagia. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a nonprofit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI® Advice for the Patient® can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with dysphagia. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.). The

information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/. PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee.
Researching Orphan Drugs Although the list of orphan drugs is revised on a daily basis, you can quickly research orphan drugs that might be applicable to dysphagia by using the database managed by the National Organization for Rare Disorders, Inc. (NORD), at http://www.rarediseases.org/. Scroll down the page, and on the left toolbar, click on “Orphan Drug Designation Database.” On this page (http://www.rarediseases.org/search/noddsearch.html), type “dysphagia” (or synonyms) into the search box, and click “Submit Query.” When you receive your results, note that not all of the drugs may be relevant, as some may have been withdrawn from orphan status. Write down or print out the name of each drug and the relevant contact information. From there, visit the Pharmacopeia Web site and type the name of each orphan drug into the search box at http://www.nlm.nih.gov/medlineplus/druginformation.html. You may need to contact the sponsor or NORD for further information. NORD conducts “early access programs for investigational new drugs (IND) under the Food and Drug Administration’s (FDA’s) approval ‘Treatment INDs’ programs which allow for a limited number of individuals to receive investigational drugs before FDA marketing approval.” If the orphan product about which you are seeking information is approved for marketing, information on side effects can be found on the product’s label. If the product is not approved, you may need to contact the sponsor. The following is a list of orphan drugs currently listed in the NORD Orphan Drug Designation Database for dysphagia: •

Coffee Break: Tutorials for Biologists19 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.20 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.21 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
The Genome Project and Dysphagia In the following section, we will discuss databases and references which relate to the Genome Project and dysphagia. Online Mendelian Inheritance in Man (OMIM) The Online Mendelian Inheritance in Man (OMIM) database is a catalog of human genes and genetic disorders authored and edited by Dr. Victor A. McKusick and his colleagues at Johns Hopkins and elsewhere. OMIM was developed for the World Wide Web by the National Center for Biotechnology Information (NCBI).22 The database contains textual information, pictures, and reference information. It also contains copious links to NCBI’s Entrez database of MEDLINE articles and sequence information. 19 Adapted 20
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 21 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process. 22 Adapted from http://www.ncbi.nlm.nih.gov/. Established in 1988 as a national resource for molecular biology information, NCBI creates public databases, conducts research in computational biology, develops software tools for analyzing genome data, and disseminates biomedical information--all for the better understanding of molecular processes affecting human health and disease.

The databases available are listed in the drop box next to “Search.” Enter “dysphagia” (or synonyms) into the search box and click “Go.” Jablonski’s Multiple Congenital Anomaly/Mental Retardation (MCA/MR) Syndromes Database23 This online resource has been developed to facilitate the identification and differentiation of syndromic entities. Special attention is given to the type of information that is usually limited or completely omitted in existing reference sources due to space limitations of the printed form. At http://www.nlm.nih.gov/mesh/jablonski/syndrome_toc/toc_a.html, you can search across syndromes using an alphabetical index. Search by keywords at http://www.nlm.nih.gov/mesh/jablonski/syndrome_db.html.
The Genome Database24 Established at Johns Hopkins University in Baltimore, Maryland in 1990, the Genome Database (GDB) is the official central repository for genomic mapping data resulting from the Human Genome Initiative. In the spring of 1999, the Bioinformatics Supercomputing Centre (BiSC) at the Hospital for Sick Children in Toronto, Ontario assumed the management of GDB. The Human Genome Initiative is a worldwide research effort focusing on structural analysis of human DNA to determine the location and sequence of the estimated 100,000 human genes. In support of this project, GDB stores and curates data generated by researchers worldwide who are engaged in the mapping effort of the Human Genome Project (HGP). GDB’s mission is to provide scientists with an encyclopedia of the human genome which is continually revised and updated to reflect the current state of scientific knowledge. Although GDB has historically focused on gene mapping, its focus will broaden as the Genome Project moves from mapping to sequence, and finally, to functional analysis. To access the GDB, simply go to the following hyperlink: http://www.gdb.org/. Search “All Biological Data” by “Keyword.” Type “dysphagia” (or synonyms) into the search box, and review the results. If more than one word is used in the search box, then separate each one with the word “and” or “or” (using “or” might be useful when using synonyms).

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on dysphagia can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to dysphagia. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to dysphagia. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “dysphagia”:

You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on dysphagia. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits.

Dysphagia
Summary: A speech language pathologist is the health care professional educated and trained to evaluate and treat children and adults with speech, language, and swallowing problems. This brochure, from the American Speech Language Hearing Association (ASHA), reviews the services that speech language pathologists provide, and reminds physicians and other health care providers of the situations where referral to a speech language pathologist can be helpful for their patients. The brochure reviews common types of speech language disorders, including articulation disorders, language disorders, aphasia (loss of the ability to comprehend words), stuttering, voice disorders, cognitive communication disorders, and dysphagia (swallowing difficulty), with a focus on the services that speech language pathologists can provide to patients with each type of disorder. Speech language pathologists are also trained to offer new possibilities for people with communication disorders through augmentative and alternative communication, including voice synthesizing computers and communication boards. The brochure concludes with the contact information for ASHA and a description of the certification process for speech language pathologists. The brochure is illustrated with black and white photographs of speech language pathologists at work. 3 figures. •

PRICE: $9.95 for members, $11.50 for nonmembers. Summary: This publication provides Nutrition Guidelines for Practice for Dysphagia developed by the Dietetics in Physical Medicine and Rehabilitation dietetic practice group. The group recognized the importance of aggressive nutrition intervention to maximize positive outcomes for patients with dysphagia, then developed and field tested the Guidelines for Practice outlined in the publication. The authors emphasize that the team approach, including the coordinated efforts of the dysphagia therapist, registered dietitian (RD), nurse, and physician, is particularly important in managing dysphagia. The ability of a patient with dysphagia to safely meet nutrient needs lies on a continuum between nothing by mouth (NPO) and total oral feedings. The guidelines address the challenges of oral and enteral feedings, and the critical transition between these two modalities. Nutrition assessment and planning, dysphagia diets, discharge planning, and patient and caregiver education are also addressed. The authors provide a field test synopsis that includes the field test objects, field test sites and design, and results. 2 tables. 10 references. (AA-M).

The NIH Search Utility The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to dysphagia. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information.

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.25
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

[NIH] Anemia: A reduction in the number of circulating erythrocytes or in the quantity of hemoglobin. [NIH] Anesthesia: A state characterized by loss of feeling or sensation. This depression of nerve function is usually the result of pharmacologic action and is induced to allow performance of surgery or other painful procedures. [NIH] Anesthetics: Agents that are capable of inducing a total or partial loss of sensation, especially tactile sensation and pain. They may act to induce general anesthesia, in which an unconscious state is achieved, or may act locally to induce numbness or lack of sensation at a targeted site.

Dysphagia
the nature of the antigen. Some antibodies destroy antigens directly. Others make it easier for white blood cells to destroy the antigen. [NIH] Anticoagulants: Agents that prevent blood clotting. Naturally occurring agents in the blood are included only when they are used as drugs. [NIH] Antidepressant: A drug used to treat depression. [NIH] Antigen: Any substance which is capable, under appropriate conditions, of inducing a specific immune response and of reacting with the products of that response, that is, with specific antibody or specifically sensitized T-lymphocytes, or both.

C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules.
