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 avascular necrosis 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 avascular necrosis, 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 avascular necrosis, 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 avascular necrosis. 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 avascular necrosis, 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 avascular necrosis. The Editors

CHAPTER 1. STUDIES ON AVASCULAR NECROSIS Overview In this chapter, we will show you how to locate peer-reviewed references and studies on avascular necrosis.

The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and avascular necrosis, 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 “avascular necrosis” (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: •

Prevalence Rates and an Evaluation of Reported Risk Factors for Osteonecrosis (Avascular Necrosis) in Crohn's Disease Source: Canadian Journal of Gastroenterology. 14(2): 138-143. February 2000. Contact: Available from Pulsus Group, Inc. 2902 South Sheridan Way, Oakville, Ontario, Canada L6J 7L6. Fax (905) 829-4799. E-mail: [email protected]. Summary: Avascular necrosis (osteonecrosis, or bone death) occurs in Crohn's disease, but the rate of this particular complication is not known. This article reports on a study undertaken to elucidate the prevalence rates and reported risk factors for osteonecrosis in patients with Crohn's disease. Over 20 years, 875 patients with Crohn's disease, 492 women (56.1 percent) and 383 men (43.9 percent) were evaluated, with patient followup

data available for a mean of 7.8 years. In this group, four men were seen with osteonecrosis. No woman was affected. All 4 patients had typical radiological, magnetic resonance imaging (MRI), or pathological changes of osteonecrosis involving the femoral heads, while two patients also had superimposed avascular necrosis involving the humeral heads. Patients ages ranged from 19 to 36 years at the time of diagnosis of their Crohn's disease, and all were white. In one patient, disease was confined to the colon, while three patients had disease involving the terminal ileum and colon. Disease behavior in two of the patients was classified as penetrating because of concomitant ischiorectal abscesses, while one patient developed a metastatic colon carcinoma (cancer). Ankylosing spondylitis (a chronic inflammatory condition affecting the spine) was present in two patients, but no other extraintestinal manifestations developed. Two patients received corticosteroids as well as parenteral nutrition during the course of their disease; two received neither treatment. The overall rate of avascular necrosis in Crohn's disease was less than 0.5 percent, but for men with Crohn's disease, the risk was about 1 percent. In this series, risk of osteonecrosis could not be attributed to corticosteroid use, parenteral nutrition, or both forms of therapy administered together. 1 figure. 2 tables. 20 references. •

Avascular Necrosis Following Renal Transplantation Source: Transplantation Proceedings. 30(7): 3034-3035. November 1998. Contact: Available from Appleton and Lange. P.O. Box 86, Congers, NY 10920-0086. (203) 406-4623. Summary: Current improved graft survival following organ transplantation depends upon the combined use of various immunosuppressive drugs. Regardless of many favorable effects of each drug, they have some side effects. Avascular necrosis (AVN) following organ transplant is one of the complications that sometimes results from treatments to preserve the organ allograft. This article reports on a study that retrospectively analyzed patients with renal allografts in order to determine the cause or precipitating conditions for AVN, to evaluate the clinicopathologic features associated with AVN, and to establish a treatment strategy. Thirteen cases (2.8 percent) of AVN of femoral head were developed among 462 patients studied. Among these, 11 cases of 365 (3.0 percent) were from living donors and 2 cases out of 97 (2.2 percent) were from cadaveric donors. The main clinical manifestations were hip joint pain and limitation of weight bearing and motion. The mean onset of first bone symptoms of AVN was 5.5 months. The type of donor, pretransplant type, and duration of dialysis showed no relation with the occurrence of AVN. The pretransplant level of blood urea nitrogen (BUN) was higher in the AVN group, but its significance is questionable due to a fluctuating level of the time of blood sampling. In this study, the cholesterol level did not show any significant relation with the AVN. Posttransplant weight gain can be suspected to be a favorable condition for AVN; however, in this population, posttransplant weight gain was not significant. The authors contend that AVN in bone may be induced by individual reactions to the steroid treatment. In the early stage of AVN, core decompression alone can be a successful treatment. In this study, 7 of 13 patients underwent core decompression. The authors conclude that they could not illustrate the definite precipitating factors for AVN in renal transplant recipients using steroids. 8 references.

Summary: This journal article for health professionals discusses the early diagnosis, evaluation, and staging of nontraumatic avascular necrosis (AVN) of the hip joint. AVN is a poorly understood condition in which a decrease in the blood supply to bone results in its death. The hip is more frequently involved than other joints, and the consequences there are more serious. Without treatment, most cases will progress to bone collapse and eventually require reconstructive surgery. Understanding the causes and pathogenesis aids early diagnosis, which leads to more effective management. In the earlier stages, the goal is to institute treatment designed to retard disease progression and prevent femoral head collapse, including core decompression, bone grafting, osteotomy, and electrical stimulation. In the later stages, after significant collapse has occurred, management is conservative until reconstructive surgery, usually total hip replacement arthroplasty, is indicated. 15 references, 4 figures, and 5 tables. (AA-M).

Federally Funded Research on Avascular Necrosis The U.S. Government supports a variety of research studies relating to avascular necrosis. 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 avascular necrosis. 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 avascular necrosis. The following is typical of the type of information found when searching the CRISP database for avascular necrosis: •

Avascular Necrosis

Summary: (provided by applicant): The goal of this research is the detection of epiphyseal ischemia and prediction of its growth sequelae using novel non-invasive magnetic resonance (MR) approaches. In animal models, we propose to determine the earliest changes in ischemia, to differentiate early from late ischemia leading to avascular necrosis; and to predict the deverlopment of growth arrest. In addition to conventional MR measures (proton density and T2 relaxation), we will investigate perfusion-related changes by early gadolinum (Gd) enhanced imaging; and diffusion related changes by line diffusion scanning and diffusion tensor imaging. We will also evaluate disturbances of the cartilaginous matrix including glycosaminoglycan depletion revealed by delayed GD enhanced imaging, and collagen content by magnetization transfer imaging. The major hypotheses are that MR parameters can 1) detect early ischemia, 2) differentiate early from late ischemia leading to sequelae, and 3) predict growth deformity through MR parameters that reflect tissue structure and vascularization of the immature epiphysis. Epiphyseal ischemia is a pathogenic pathway shared by many common pediatric disorders. Ischemia leading to avascular necrosis of the femoral head frequently causes hip deformity and disability in childhood. A hip that grows abnormally also predisposes to degenerative joint disease in adult; more than half of all adults with osteoarthritis of the hip suffered hip diseases as children. Imaging of cartilaginous disorders serves to guide early therapy, prevent or minimize deformity, and detect children predisposed to premature cartilage degeneration in adulthood. The specific aims are to: 1) determine the MR tissue characteristics of normal epiphyseal cartilage. Specifically, we wish to test whether the greater cellularity and vascularization of immature epiphyseal cartilage result in different MR tissue characteristics; 2) in early ischemia, determine temporal and spatial differences between diffusion imaging, T2 maps and Gd-enhanced imaging; 3) in prolonged ischemia, determine which MR parameters best predict irreversible damage; and 4) in a model of avascular necrosis, determine which MR parameters predict abnormal growth.

Project Title: HOST FACTORS AND ETIOLOGY OF LEUKEMIA Principal Investigator & Institution: Davies, Stella; Professor and Jacob G. Schmidlapp Endowe; Pediatrics; University of Minnesota Twin Cities 200 Oak Street Se Minneapolis, Mn 554552070 Timing: Fiscal Year 2002; Project Start 18-DEC-2001; Project End 30-SEP-2002 Summary: Individuals show considerable variation in their ability to metabolize therapeutic drugs, and in the metabolism of potentially toxic chemicals occurring in the environment. The variability is due in large part to genetic differences (polymorphisms) in genes involved in detoxification or in the response to genetic damage. Preliminary data indicate that polymorphic host factors are important in response to leukemia treatment, in etiology of leukemia, and in the occurrence of complications of treatment. The overall aim of this proposal is to develop a DNA resource from children with cytogenetically well characterized and uniformly treated leukemia, and to use it to analyze host factors influencing the outcome of treatment for leukemia and the etiology of leukemia. This study is a correlative study complementing and expanding NCI funded Children's Oncology Group (COG) chemotherapy treatment trials. In this investigation we will examine allele frequencies at polymorphic sites in genes involved in drug metabolism, DNA repair, DNA synthesis and in defense against oxidant damage in children enrolled on COG therapeutic studies. The data will be analyzed to determine whether allelic variation at these sites influence the outcome of therapy. In

addition, allele frequencies will be compared with those seen in normal population to determine whether they influence susceptibility to leukemia. Lastly, the DNA collected will serve as a resource for studies of polymorphisms which influence complications of therapy such as second cancers, avascular necrosis of bone and thrombotic events.

Project Title: LUPUS COHORT Principal Investigator & Institution: Petri, Michelle A.; Associate Professor; Medicine; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 30-SEP-1996; Project End 31-MAR-2007 Summary: (provided by applicant): The Hopkins Lupus Cohort is an ongoing, prospective study in which SLE patients are followed by protocol, with visits at a minimum of every 3 months, now in its 16th year. The Cohort is racially balanced, with one-half of the members being African-American, and reflects a broad socioeconomic range. The Cohort represents a 15 year investment in the study of SLE outcomes, sponsored by NIH. It has led to a unique, prospective database of demographic, social, clinical and laboratory (routine, serologic, and antiphospholipid antibody) measures. The four major accomplishments of the Cohort during the last funding period were: 1) the determination that serologic markers of disease activity, such as anti-dsDNA, C3, and C4, have limited utility in the prediction of SLE flare; 2) the determination that the cumulative prednisone dose is predictive of coronary artery disease and osteoporosis, whereas high-dose prednisone is predictive of avascular necrosis; 3) the determination that antiphospholipid antibodies are associated with future risk of thrombosis and with atherosclerosis; and 4) the finding that the poor health status of SLE patients is associated with fibromyalgia, whereas fibromyalgia itself correlates highly with neurally-mediated hypotension, a form of autonomic neuropathy. In this revised grant, four new specific aims will be undertaken. First, in the cohort as a whole and in an inception cohort followed since diagnosis, we will determine the relative importance of disease activity versus corticosteroid treatment as a predictor of specific types of organ damage. Second, in a study of 75 patients seen monthly, we will investigate cytokines and platelet-related factors as predictors of disease activity. Third, 250 patients from the inception cohort will have carotid duplex and helical CT (for coronary calcification scores) at baseline and 2 years later to determine associates and predictors of atherosclerosis, including traditional and novel cardiovascular risk factors. Fourth, we will assess, in 100 SLE patients with and 100 without fibromyalgia, the frequency of autonomic neuropathy and the correlation with health status.

Project Title: NONSPECIFIC BONE PAIN AND AVASCULAR NECROSIS Principal Investigator & Institution: Chen, Edward; University of Minnesota Twin Cities 200 Oak Street Se Minneapolis, Mn 554552070 Timing: Fiscal Year 2002 Summary: For the patient with a successful organ transplant, the musculoskeletal complications of non-specific bone pain and osteonecrosis all too frequently arise within the first several years after transplantation and are debilitating just as the patient is enjoying a new lease on life. The long term objectives of this proposal are to study 3 issues central to the musculoskeletal problems encountered by transplant patients. (1) Nonspecific bone pain (NSBP) is a newly recognized entity which is poorly understood and is secondary to immunosuppression. It may be related to early stage osteonecrosis.

Avascular Necrosis

This proposal will prospectively study the natural history, improve the diagnostic criteria and test calcium channel blockers in the treatment of NSBP using a double blind, randomized study as well as explore a potential relationship to osteonecrosis. (2) Osteonecrosis of the femoral head (ONFH) is a dreaded complication of immunosuppression as it is crippling and there is no treatment which can reliably salvage the hip joint. A reversible stage of osteonecrosis has recently been described. This proposal will use MRI to prospectively study whether or not a reversible stage exists and the prognostic factors which may predict which patients will develop progressive collapse f the femoral head. (3) At present, surgical procedures to preserve the hip joint are unreliable in their success. This proposal will use functional and clinical outcomes measurement to study a new procedure, core decompression with methylmethacrylate cement packing, designed to prevent or forestall the development of end-stage arthritis in patients with either pre- femoral head collapse ONFH (single blind, randomized, prospective study), or post-femoral head collapse ONFH (single blind, randomized, prospective study), or post-femoral head collapse ONFH (prospective study).

Project Title: ORGAN TRANSPLANTATION IN ANIMALS AND MAN Principal Investigator & Institution: Matas, Arthur J.; Professor; Surgery; University of Minnesota Twin Cities 200 Oak Street Se Minneapolis, Mn 554552070 Timing: Fiscal Year 2003; Project Start 30-SEP-1992; Project End 31-MAR-2008 Summary: This is an application for competitive renewal of a program project grant which has been active for 34 years. It involves many investigators and many different projects all relating to the improvement of the results of organ transplantation. The basic overall OBJECTIVES of this grant are to: 1. analyze and isolate the clinical problems involved in organ transplantation and precisely document clinical laboratory correlations; 2. organize clinical trials and experimental approaches based on available data, to solve clinical problems. Within these objectives, all projects are organized into two essential AIMS: AIM 1: TO PREVENT ORGAN DESTRUCTION. This includes not only immunological manipulations designed to prevent rejection but also those designed to prevent nonimmunologic graft loss, to prolong patient survival, and to modify or control drug toxicity and recurrent disease; AIM 2: TO MAXIMIZE REHABILITATION: The focus here is on minimizing complications and maximizing compliance with the immunosuppressive regimen. Within this framework, the current applications include projects addressing morbidity, mortality, and late graft loss (2 projects), chronic graft loss (3 projects), morbidity from avascular necrosis (1 project), and long-term living donor follow-up (1 project). The 2 Cores--Clinical and Administrative--support all projects. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

this multi-institutional collaborative study is designed to follow a standardized protocol that will characterize and compare the radiographic, histologic and surgical course of patients. SCD is the most common cause of avascular necrosis (AVN) of the hip in young patients. By age 25 almost half of all SCD patients have AVN. Eventual total collapse of the femoral head eventually necessitates hip replacement. Unfortunately, his arthroplasty fails in over 50-75% of cases. A major focus of the health community is to develop effective therapy that will half the progression of early AVN. The National Preoperative Transfusion Study Group recently reported a high perioperative morbidity rate with hip replacement and experience with decompression coring. A pilot prospective study to evaluate decompression coring in 13 hips was completed and demonstrated long-term improvement in both pain and range of motion in all early stage hips. Based on the preliminary data in SCD and non-SCD, a multi-institutional prospective study by SCD experts, orthopedic surgeons and physiatrists is planned to determine the efficacy od decompression coring in SCD. The study will randomize 100 patients with early AVN to a standardized program of non- weight bearing with crutches for 6 weeks versus decompression coring procedure. All patients will follow standard care protocols including Harris hip score and Oberg scale of lower extremity function, radiographic and laboratory testing every 3 to 6 months for an average of 3 years. Radiographic (MRI) and histologic sections of the core biopsy will be centrally analyzed. The extent of the lesion on MRI and pathology will be quantitated and compared to the clinical course in order to investigate the predictors of outcome. In summary, this study if successful, will change the approach to hip disease in SCD patients and result in improved quality of life and decreased morbidity from Surgery.

Project Title: SLEEP, FATIGUE, AND DEXAMETHOSONE IN CHILDHOOD CANCER Principal Investigator & Institution: Hinds, Pamela S.; Director of Nursing Research; St. Jude Children's Research Hospital Memphis, Tn 381052794 Timing: Fiscal Year 2002; Project Start 30-SEP-2000; Project End 30-JUN-2004 Summary: Mounting evidence indicates that adding dexamethasone to the therapy for children and adolescents diagnosed with lymphoblastic leukernia contributes to more positive long-term outcomes such as lower rates of meningeal leukemia. The significant positive contributions of dexamethasone have not occurred without adverse effects including avascular necrosis. mania and psychosis, and aberrant sleep and fatigue. These adverse effects could be related to inter-individual variability in the systemic exposure to dexamethasone and if so, the adverse effects could serve as behavioral indicators of patient sensitivity to the dosing schedule. To determine whether dexamethasone dosing schedules need to be individualized to minimize adverse effects while maintaining antileukernic effects, the relationship between inter-individual variability and adverse effects must be established. The overall purpose of this two-site study is to determine the relationship between systemic exposure to dexamethasone and patients' sleep and fatigue by comparing multiple indicators of patient sleep and fatigue in two consecutive 5-day periods during Continuation therapy off and on dexatnethasone. Approximately 134 children and adolescents with low or standard fisk ALL will wear a wnist actigraph for the two consecutive 5-day study periods and will complete a self-report fatigue questionnaire during a telephone interview on Days 2 and 5 of both study periods. Their parents will complete a sleep diary and a fatigue questionnaire on Days 2 and 5 of both study periods regarding their child's sleep and fatigue patterns. In addition, on Day I of the on dexamethasone 5-day study period,

patients will-have sequential blood samples collected pre- and post- the morning dose of dexamethasone. These samples will be analyzed for dexamethasone pharmacokinetics and genetic polymorphism. Using these data, we will test the hypothesis that dexamethasone contributes to aberrant sleep and increased fatigue in children and adolescents with ALL, and that the altered sleep and fatigue are related to the pharmacokinetics of the drug. Our study findings will explicate the relationship between sleep efficiency and fatigue, and between sleep, fatigue, and systemic exposure to dexamethasone.

E-Journals: PubMed Central3 PubMed Central (PMC) is a digital archive of life sciences journal literature developed and managed by the National Center for Biotechnology Information (NCBI) at the U.S. National Library of Medicine (NLM).4 Access to this growing archive of e-journals is free and unrestricted.5 To search, go to http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=Pmc, and type “avascular necrosis” (or synonyms) into the search box. This search gives you access to full-text articles. The following is a sample of items found for avascular necrosis in the PubMed Central database: •

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.

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 AVASCULAR NECROSIS Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and avascular necrosis.

Finding Nutrition Studies on Avascular Necrosis 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 “avascular necrosis” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

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.

CHAPTER 4. PATENTS ON AVASCULAR NECROSIS 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.8 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 “avascular necrosis” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on avascular necrosis, we have not necessarily excluded non-medical patents in this bibliography.

Patent Applications on Avascular Necrosis As of December 2000, U.S. patent applications are open to public viewing.9 Applications are patent requests which have yet to be granted. (The process to achieve a patent can take several years.) The following patent applications have been filed since December 2000 relating to avascular necrosis:

The abnormality may be corrected by first accessing and boring into the damaged tissue or bone and reaming out the damaged and/or diseased area using any of the presently accepted procedures or the damaged area may be prepared by expanding a bag within the damaged bone to compact cancellous bone. After removal and/or compaction of the damaged tissue the bone must be stabilized. Excerpt(s): This application claims priority from U.S. patent application Ser. No. 09/909,667, filed Jul. 20, 2001, which claims priority to U.S. Provisional Application No. 60/219,853 filed Jul. 21, 2000, the entirety of which is incorporated herein by reference. This invention relates to methods and devices for correcting bone abnormalities and involves the use of a surgical mesh bag which is inserted into a prepared cavity in bone. The bag is inflated using bone replacement material to expand and fill the cavity. U.S. Pat. Nos. 5,549,679 and 5,571,189 to Kuslich, describe a device and method for stabilizing the spinal segment with an expandable, porous fabric implant for insertion into the interior of a reamed out disc which is packed with material to facilitate bony fusion. In the present invention, a similar bag is used to correct bone abnormalities including, but not limited to, bone tumors and cysts, tibial plateau fractures, avascular necrosis of the femoral head and compression fractures of the spine.

System, device, composition and method for treating and preventing avascular or osteonecrosis Inventor(s): Fetto, Joseph F.; (New York, NY), Leali, Alejandro; (Hackensack, NJ) Correspondence: Joseph F. Fetto, M.D.,; Alejandro Leali, M.D.; Suite 7-J; 300 E. 56th ST.; New York; NY; 10022; US Patent Application Number: 20030135214 Date filed: January 15, 2002 Abstract: A vascular necrosis of the hip is a common disease that usually affects a young, active patient population. As the disease progresses the undermined structural integrity of the subchondral bone leads to articular collapse and subsequent osteoarthrosis. The ideal treatment is one that hinders or arrests the progression of the disease averting articular collapse and a joint replacement surgery. Several non-surgical and surgical procedures have been described to treat avascular necrosis: core decompression, osteotomies of the hip, non-vascularized and vascularized bone grafts. The purpose of this paper is to describe a surgical strategy that attempts to address the

Patents 67

multiple factors involved in the progression of the disease: deficits in structural support, increased intraosseous pressure and the bone healing process. This is accomplished through a routine core decompression procedure combined with the insertion of two bone interference screws into the subchondral bone of the femoral head to provide structural support and the use of osteoinductive bone allograft (demineralized bone matrix) in an effort to accelerate the bone response. Prospective studies are currently underway to assess long-term outcomes. Excerpt(s): This invention is concerned with the field of treatment and prevention of pain, discomfort, deformity or disability associated with loss of bone structure, strength or support that accompanies osteonecrosis or avascular necrosis of various load-bearing musculoskeletal structures. Osteonecrosis (avascular necrosis, aseptic necrosis or subchondral avascular necrosis) does not represent a particular disease but the final common pathway of a number of conditions leading to bone death. Trauma, corticosteroids, alcoholism and connective tissue disorders have been historically linked to the occurrence of avascular necrosis. It most commonly involves the femoral head, followed by the knee, the humeral head, and the small bones of the wrist and foot. The prevalence of avascular necrosis is unknown; however, 10,000 to 20,000 new cases of avascular necrosis of the hip have been estimated to develop every year [1]. Approximately 10 to 12 percent of the total hip arthroplasties performed in the U.S. are a consequence of avascular necrosis and the ensuing articular collapse and osteoarthrosis [2]. The average age of patients undergoing total hip replacement for avascular necrosis remains below 40 years [3] with a life expectancy exceeding forty years [4].

PRICE: $129.00 plus shipping and handling. ISBN: 1550091220. Summary: This chapter on ischemic necrosis of bone is from the second edition of a book devoted to the details of medical, surgical, and supportive management of patients with Crohn's disease (CD) and Ulcerative Colitis (UC), together known as inflammatory bowel disease (IBD). Osteonecrosis (ON) and avascular necrosis of bone (AVN) are the commonly used terms for an entity that also is referred to as ischemic necrosis of bone, aseptic necrosis, and osteochondritis dissecans. Because the bone is truly avascular (no blood flow) only in the end stage of the disease, the term ischemic necrosis of bone is preferred, emphasizing the period of ischemia (reduced or intermittent blood flow) that precedes actual bone death. Pathologically, it is characterized by death of cells in bone, resulting from an interruption of blood supply to bone. Osteonecrosis generally is divided into two major forms: post-traumatic and nontraumatic. Neither minor nor major trauma causes ON unless there has been a fracture or dislocation resulting in physical damage to the arterial circulation. Diseases, such as inflammatory bowel disease (IBD), in which corticosteroids often are used in high doses and for prolonged periods pose an increased risk. Patients with IBD who present with ON may be younger than other patients with ischemic bone changes, and some have ON without having taken steroids. There is a correlation between involvement of the talus (ankle) with the diagnosis of IBD and the long-term administration of glucocorticoids. Multiple sites of bone involvement also correlate with the diagnosis of IBD or systemic lupus erythematosus, perhaps because both diseases often are treated with high doses of steroids for long periods. If the bone disease is untreated, the majority of patients have eventual destruction of the joints. Conservative or medical management consists primarily of non loadbearing in an attempt to prevent collapse while repair is completed. Only about one quarter of patients improve spontaneously and have a tolerable disability. Joint replacement is a possibility, but is not as successful in young and otherwise physically active individuals (which tends to be the case in IBD and osteonecrosis). 1 figure. 2 tables. 11 references.

IBD in Infants, Children, and Adolescents: Unique Aspects of Diagnosis and Treatment Source: Intestinal Fortitude. 9(3): 1-3. 1999. Contact: Available from Intestinal Disease Foundation. 1323 Forbes Avenue, Suite 200, Pittsburgh, PA 15219. (412) 261-5888. Fax (412) 471-2722. Summary: This newsletter article outlines some of the unique features and considerations in the diagnosis of inflammatory bowel disease (IBD) in infants, children, and adolescents. Although IBD (ulcerative colitis and Crohn's disease) has been diagnosed in early infancy, the majority of cases occur between the ages of 10 and 21. One third of the total cases of IBD occur in the pediatric age group. The author stresses that when a child under 10 presents with signs and symptoms of IBD, the physician has to be careful with the diagnosis because a number of other conditions can mimic it. In infants who have persistent diarrhea and rectal bleeding with colitis, the picture may strongly resemble ulcerative colitis, when in fact the symptoms may have been caused by food allergy. Elimination of suspected food allergens, such as milk or soy protein, will improve the clinical picture, and many times these infants will grow out of the tendency for allergies by the age of 2. School age children may have Henoch Schonlein purpura, a condition characterized by inflammation of the small blood vessels that can affect any part of the body. The gastrointestinal symptoms can include abdominal pain, diarrhea, and rectal bleeding, while x rays and colonoscopies may show changes that mimic Crohn's disease. A unique feature of adolescence is the struggle between parental dependency and self reliance, which may contribute to a mistaken or delayed diagnosis. The impact of chronic inflammation on growth can be another unique aspect of IBD in children and adolescents. In addition, the impact of chronic illness (including the effects of chronic use of prednisone) on the emotional makeup of children is an important factor which must be addressed by the gastroenterologist. Physicians must also be diligent in monitoring these children for other side effects of prednisone, such as osteopenia (decreased bone density) and avascular necrosis (death of areas of bone due to insufficient blood supply).

Avascular Necrosis

Hypothyroidism and thyrotoxicosis can affect the musculoskeletal system. The manifestations of congenital hypothyroidism and hypothyroidism occurring in childhood are usually dominated by cognitive deficiencies and developmental delays. In adults, hypothyroidism may result from autoimmune and postablative mechanisms, pituitary failure, or iodine deficiency. Hypothyroid adults usually have manifestations consistent with low basal metabolic rate. An arthropathy may occur, or hypothyroidism may be confused with fibromyalgia. Hypothyroidism is also associated with other musculoskeletal and rheumatic diseases, including polymyositis, carpal tunnel syndrome, avascular necrosis of the hip, polymyalgia rheumatica, giant cell arteritis, rheumatoid arthritis, and systemic lupus erythematosus. Thyrotoxicosis may also have musculoskeletal manifestations, including myopathy, osteoporosis, and shoulder pain. Graves' disease, an autoimmune disease caused by antibodies directed against the TSH receptor in the thyroid, is associated with pretibial myxedema and thyroid acropachy. 2 tables and 35 references. •

Total Hip Replacement: Relieve Pain, Improve Mobility Source: Mayo Clinic Newsletter. April 18, 2003. 7 p. Contact: Available from Mayo Foundation for Medical Education and Research. Website: www.mayoclinic.com. Summary: This newsletter article provides information to patients considering hip replacement surgery. Hip replacements are performed for many reasons including injury, rheumatoid arthritis, avascular necrosis, and osteoarthritis. Weight, bone density, age, and overall health need to be considered before having surgery. Doctors usually recommend that patients be older than 60 years of age, as the replaced joint lasts an average of 15 to 20 years. Patients should discuss the surgical procedure, risks, postsurgery medications, and possible complications of the surgery with their doctor. Patients should also plan for their return home. The surgery itself takes 2 to 3 hours and is performed under general or regional anesthesia. The femoral head of the thighbone is replaced with a metal ball and is attached to a metal stem fitting into the thighbone. Possible complications include dislocation, infection, and blood clots. Some patients may have long-term complications including loosening, breaking the prosthesis, and an inflammatory reaction. It takes approximately 6 to 8 weeks to recover from this surgery and during that time the patient's activities will be limited. After a follow-up with the surgeon to ensure that the hip is healing properly, most patients are able to resume their usual activities.

The hip includes the hip joint and the area surrounding the joint from the waist to the upper leg. The location of the pain in the hip area can help determine whether the problem is related to the joint. The groin area is the most common location for pain related to hip joint disorders. However, pain from hip joint disorders can also occur on the side of the hip, the upper thigh, the buttock, and, occasionally, the knee. Osteoarthritis is one of the most common causes of hip joint pain. Other causes include inflammatory arthritis, avascular necrosis, fractures, infection, tumor, and congenital defects in the hip joint structure. Hip area pain not related to the joint can be caused by

various conditions, including trochanteric bursitis, ischial bursitis, pinched sciatic nerve, sacroiliac joint pain, and hernia. A person needs to see a physician for a physical examination if hip pain causes a limp or significantly interferes with daily activities. Treatments vary depending on the cause of the pain. 1 figure.

Coffee Break: Tutorials for Biologists18 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.19 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.20 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/.

18 Adapted 19

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. 20 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.

85

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 avascular necrosis can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internetbased 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 avascular necrosis. 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 avascular necrosis. 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 “avascular necrosis”:

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 avascular necrosis. 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.

Order Number: AR-150QA (booklet), or AR-150L QA (large print). Summary: This fact sheet for people with avascular necrosis, or osteonecrosis, uses a question and answer format to provide information on the disease. Avascular necrosis, which most commonly affects the ends of long bones, is described as a disease resulting from the temporary or permanent loss of the blood supply to the bones. Causes can be injuries, certain risk factors, steroid medications, and alcohol use. The fact sheet explains how, in its early stages, people may not experience any symptoms, how the disease progresses, how it is diagnosed, and what are the available treatments. It also describes current research on the causes and treatment for the disease. Two voluntary health organizations are listed for additional information about avascular necrosis. A large print version of this fact sheet is also available. The National Guideline Clearinghouse™

The National Guideline Clearinghouse™ offers hundreds of evidence-based clinical practice guidelines published in the United States and other countries. You can search this site located at http://www.guideline.gov/ by using the keyword “avascular necrosis” (or synonyms). The following was recently posted: •

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 avascular necrosis. 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.

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.21

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

calcification, macrocalcification and microcalcification. Macrocalcifications are large deposits and are usually not related to cancer. Microcalcifications are specks of calcium that may be found in an area of rapidly dividing cells. Many microcalcifications clustered together may be a sign of cancer. [NIH] Calcium: A basic element found in nearly all organized tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.

Collagen is differentiated from other fibrous proteins, such as elastin, by the content of proline,

106

Avascular Necrosis

hydroxyproline, and hydroxylysine; by the absence of tryptophan; and particularly by the high content of polar groups which are responsible for its swelling properties. [NIH] Collapse: 1. A state of extreme prostration and depression, with failure of circulation. 2. Abnormal falling in of the walls of any part of organ. [EU] Colon: The long, coiled, tubelike organ that removes water from digested food.

[NIH] Combination chemotherapy: Treatment using more than one anticancer drug. [NIH] Combined Modality Therapy: The treatment of a disease or condition by several different means simultaneously or sequentially. Chemoimmunotherapy, radioimmunotherapy, chemoradiotherapy, cryochemotherapy, and salvage therapy are seen most frequently, but their combinations with each other and surgery are also used. [NIH] Complement: A term originally used to refer to the heat-labile factor in serum that causes immune cytolysis, the lysis of antibody-coated cells, and now referring to the entire functionally related system comprising at least 20 distinct serum proteins that is the effector not only of immune cytolysis but also of other biologic functions. Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols 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. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
