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 hemangioma 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 hemangioma, 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 hemangioma, 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 hemangioma. 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 hemangioma, 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 hemangioma. The Editors

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

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

Central Hemangioma: Review and a Case Report Source: Annals of Dentistry. 54(1-2): 22-24. Summer-Fall 1995. Summary: This article presents a case report of a patient with central hemangioma, a rare vascular tumor of bone. When present in the head and neck region, it usually affects the vertebrae and skull; it very rarely affects the jaw bones. The early detection and treatment are important, as any minor trauma may result in fatal hemorrhage. The authors present the case report of an 18 year old male with the complaint of slowly increasing painless swelling on the right side of the mandible since 5 years of age; the swelling had increased rapidly in size in the past 4 to 5 months. The patient also gave a history of frequent bleeding from the affected site while brushing. The authors describe the symptoms and diagnosis of central hemangioma in this patient. They also briefly review the treatments used for hemangioma. 26 references. (AA-M).

Hemangioma

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

Project Title: AAV VECTORS EXPRESSING ANGIOGENIC FACTORS FOR CHD Principal Investigator & Institution: Kan, Yuet W.; Professor of Medicine; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2002 Summary: Intramuscular injection of AAV vectors is an efficient way of delivering secretory proteins such as erythropoietin and Factor IX. It appears, therefore, that this vector could be useful for delivering angiogenic factors for the treatment of coronary heart disease. Preliminary experiments indicate that this model of administration may indeed by useful. VEGF delivered by AAV vectors into the myocardium by intracardiac injection was compared in mice with or without coronary artery ligation. In mice with ligated coronary arteries, ne blood vessel formation was seen, whereas in the mice with intact coronary, very few blood vessels were seen. (1) The first aim of this project is to extend these studies to a larger number of animals. Because the pathophysiological changes associated with ligation of the coronary artery are much better established in rats, these studies will be performed on rats. The animals will be examined by electrophysiology and echocardiography before they are sacrificed for histological examination for pathology and blood vessel formation. Also, a new method for three dimensional imaging of cardiac blood vessels will be used. (2) A second aim of this project is to investigate methods of regulating angiogenic factors of expression in the myocardium. As it has been shown that high level of expression of VEGF in the myocardium may result in hemangioma formation, it is important to control the expression of angiogenic factors. The first may result in hemangioma formation, it is important to control the expression of angiogenic factors. The first mode of regulation that we will investigate that we will investigate is to use the hypoxia responsive element from the erythropoietin gene. Preliminary data showed several copies of this element arranged in tandem could increase the expression of genes in response to anoxia. Other inducible promoters such as the tetracycline or the progesterone receptor system will be tested. (3) A third aim is to improve the quality and quantity of new blood vessel

PROTEASE-ADHESIN

FROM

Principal Investigator & Institution: Hill, Etheleen M.; Meharry Medical College 1005-D B Todd Blvd Nashville, Tn 37208 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2007 Summary: The hemotrophic bacterium Bartonelta bacilliformis, is the causative agent of two distinct clinical syndromes known as Oroya fever and verruga peruana. The Oroya fever syndrome is characterized by the presence of the organism on and inside erythrocytes. Verruga peruana is the tissue phase of the disease in which hemangiomalike lesions can be found on the face and lower extremities due to the presence of the organism inside endothelial cells and the pronounced cell proliferation. Our long-term goal is to understand the role of important ligand-receptor interactions that mediate attachment of the organism to host cells and promote cell invasion. The objective of this application is to determine the role of a protease-adhesin in BartonelIa attachment and invasion. The central hypothesis is that this protein which is surface-exposed on Bartonella mediates the binding of the organism to host cells and subsequent internalization. The hypothesis has been formulated based on strong preliminary data which suggest that this protein interacts with commercially purified integrin proteins and human plasma fibronectin that are involved in a variety of cell adhesion phenomena. The rationale for doing this research is that new innovative approaches and strategies for prevention and treatment of Bartonella infection will be possible once we have a better understanding of Bartonella/host cell interactions. The central hypothesis will be tested and the objective of the application accomplished by pursuing three specific aims: 1)To isolate the protease-adhesin by anion exchange chromatography of detergent extracts; 2) To characterize the interactions between the purified proteaseadhesin and host cells and extracellular matrix proteins utilizing radiolabeled binding and invasion assays and enzyme-linked immunosorbent assays; and 3) To clone the gene encoding the Bartonella protease-adhesin utilizing immunological screening of a lambda ZAP B. bacilliformis genomic library and blue/white color selection of recombinant clones.

Hemangioma

Summary: The goal of this Core is to provide DNA, RNA, protein and tissue samples, as well as lymphoblasts and hemangioma derived endothelial cells for analysis related to all three projects of this Program Project. In addition, the Core collects clinical information and pedigree data pertinent to the samples. This data is essential not only for the genetic approaches (Projects 1 and 3), but also when analysing tissues or cell lines for differential expression, somatic mutations or altered behaviour in cell culture in vascular anomaly subtypes (Projects 1, 2 and 3). The sample collection will also ultimately serve for fast and efficient screening of newly identified candidate genes in a well-characterized sample set. The work of Core C is largely based on the extensive collaborative work and expertise of Dr J.B. Mulliken, Vascular Anomalies Center, Boston and Dr L.M. Boon, Vascular Anomalies Center, Brussels. This collaboration has led to numerous clinical publications describing novel diagnostic measures, prevalence and treatment of vascular anomalies. In addition, in collaboration with Drs Vikkula and Olsen, genetic background has been elucidated for certain forms. On this basis, we have already collected 115 families, 291 blood samples, 317 tissue samples, and established 125 cell lines. This unique collection of well-characterized samples will be enlarged continuously throughout the Program Project. This allows access of all three Projects of this Program Project to sufficient numbers of samples that are essential for achieving the Aims.

Project Title: CUTANEOUS HEMANGIOMAS AND SIGNAL TRANSDUCTION Principal Investigator & Institution: Arbiser, Jack L.; Assistant Professor; Dermatology; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2002; Project Start 01-SEP-2001; Project End 30-JUN-2006 Summary: (provided by applicant): This application focuses on the mechanisms or pathogenesis or hemangiomas and associated angiogenesis. Hemangiomas are the most common cutaneous vascular lesions of childhood, and are present in 5 percent of infants at 1 year of age. These hemangiomas may grow to large sizes and may result in compression of vital structures or high output cardiac failure. Treatment of large hemangiomas requires lengthy treatment with steroids or alpha interferon, and surgery. These treatments are associated with a high level of morbidity, including growth retardation, infection, and irreversible neuropathy. A significant number of these hemangiomas do not respond to treatment, resulting in death. The signal transduction pathways that underlie these lesions are not completely understood. Hemangiomas are a reactive process associated with an imbalance in the angiogenic switch, resulting in the proliferation and migration of host endothelial cells to an angiogenic stimulus (host recruitment). This process may involve autocrine and paracrine loops between endothelial specific ligands and their receptors on normal endothelial cells. The principal investigator has developed a mouse model of hemangiomas, using the murine neonatal endothelial cell line A9519. This model recapitulates the clinical and histologic characteristics of human hemangiomas. Previous studies performed by our laboratory have shown that activation of a single signal transduction pathway, phosphoinositol-3kinase, is critical for the regulation of angiogenesis in SYR cells, which are derived from adult murine endothelium through the sequential introduction of SV4O large T antigen and H-ras. We believe that activation of both the mitogen activated protein kinase (MAPK) and phosphoinositol-3-kinase (PI-3.-kinase) pathways are required for growth of benign hemangiomas in mice and humans. Inhibition of these pathways provides therapeutic possibilities for the treatment of hemangiomas and other cutaneous angiogenic disorders. Hypothesis: Activation of both MAPK and P1-3-kinase pathways

is required for hemangioma growth in vivo. Specific Aim 1. To determine the presence of autocrine loops in hemangioma cells in vitro and in vivo. Specific Aim 2. To determine the role of activation of the MAPK and PI-3-kinase pathways in a murine model of hemangioma using dominant negative signal transduction genes and pharmacologic inhibition. Specific Aim 3. To determine the identity and function of downstream effectors of MAPK and PI3-kinase in hemangiomas. The studies outlined in this proposal will contribute to our basic understanding of cutaneous angiogenesis. In addition, insights gained from the studies described in this proposal will lead to more accurate diagnosis of other endothelial neoplasms, such as hemangioendothelioma, Kaposi's sarcoma, and angiosarcoma, as well as lead to novel therapeutic approaches to cutaneous disease through signal transduction modulation.

STURGE-WEBER

Principal Investigator & Institution: Juhasz, Csaba; Pediatrics; Wayne State University 656 W. Kirby Detroit, Mi 48202 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-JUN-2007 Summary: (provided by applicant): Sturge-Weber syndrome (SWS) is a neurocutaneous syndrome that typically manifests as seizures, neurological signs, and progressive cognitive decline in the first few years of life. Although the disease is often progressive, there are, at present, no objective markers to identify patients at highest risk for a devastating outcome. The overall aim of this proposal is to collect quantitative structural and functional neuroimaging data in a prospective, longitudinal way in children with unilateral SWS, and to correlate these with clinical variables. Using positron emission tomography (PET) and magnetic resonance imaging/spectroscopy (MRI/MRS), we expect to find (based on our preliminary data) objective markers that identify children with SWS who are at major risk for progressive cognitive decline and severe seizures. Since surgical resection of affected brain regions may be an effective way of preventing clinical progression, and facilitating brain plasticity in young children, the findings will have a major impact on clinical management in SWS by establishing a ground for early surgical intervention in carefully selected patients. This expectation is based on our preliminary studies showing that brain glucose metabolic abnormalities are closely related to the clinical progression. Specifically, large cortical regions with mild hypometabolism are associated with severe seizures, while rapid unilateral structural brain damage may be paradoxically associated with good cognitive outcome, supposedly by facilitating reorganizational processes in unaffected brain regions. Increased glutamate concentration and decreased NAA detected by MRS in the affected cortex appear to be related to epileptogenicity and progressive neuronal dysfunction, respectively. In this study we propose four aims: Aim l. To determine the changes (among 3 measurements made at one year intervals) in abnormalities of metabolism and

structure in the affected hemisphere in young children (3 months - 5 years of age at time of first scans) with unilateral SWS. Aim 2. To identify patterns of metabolic and structural brain abnormalities that are related to development of cognitive impairment. Aim 3. To identify patterns of metabolic and structural brain abnormalities that are associated with high seizure frequency. Aim 4. To determine whether cortical resection in SWS can reverse cognitive decline. The study will identify neuroimaging markers, which may be used as diagnostic predictors of clinical progression in SWS. This may aid in the selection of patients who could benefit from early resective surgery. The MRS studies can also provide novel data on the role of glutamatergic neurotransmitter toxicity in the pathophysiology of SWS; this may open new therapeutic approaches. Further, the findings will help to better understand the effect of early brain lesion on reorganizational processes in the developing brain.

Project Title: MECHANISMS OF CELL KILLING INDUCED BY RETROVIRUSES Principal Investigator & Institution: Young, John a T.; Professor; Oncology; University of Wisconsin Madison 750 University Ave Madison, Wi 53706 Timing: Fiscal Year 2002; Project Start 01-JUL-1994; Project End 31-MAY-2004 Summary: (Adapted from Summary): This application studies the mechanism which cytopathic retroviruses kill their target cells and how this induction of cell death relates to viral pathogenesis in vivo. These studies focus on the avian leukosis virus-B (ALV), whose receptor, TVB, is a functional death receptor in the TNFR-family. Binding of ALV-B Env to the TVB receptor can lead to cell death. Five specific aims are proposed. The first examines whether the TVB receptor plays a direct role in cell-killing following infection by cytopathic subgroups of ALV. This will be tested using dominant negative forms of the receptor. The second examines the role of Nf-kappaB in the signaling pathway. The third examines whether cells chronically infected with ALV-B are protected against TVBL-induced death. The fourth aim studies whether viral superinfection contributes to the cytopathic effects. The fifth aim studies a variant of ALV-A, the avian hemangioma virus, which induces cell-killing. These studies will identify the cell death pathway induced possibly through the TVA receptor.

Project Title: MOLECULAR BASIS OF HEMANGIOMAS Principal Investigator & Institution: Olsen, Bjorn R.; Hersey Professor of Cell Biology & Chair; Harvard Sch of Dental Med Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2008 Summary: The long-term goals of the studies proposed in Project 1 are to identify the molecular mechanisms responsible for the occurrence and characteristic features of juvenile (infantile) hemangiomas in humans. We have demonstrated that vascular endothelial cells isolated from hemangioma lesions are clonal populations and show increased migration and proliferation in culture. They also show an abnormal migratory response to endostatin, an antiangiogenic proteolytic fragment derived from the nonfibrillar collagen XVIII. To test the hypothesis that hemangiomas are caused by somatic mutations in genes involved in the regulation of endothelial cell behavior, several alternative strategies are proposed to identify the responsible genes. Collaborative mapping studies to identify hemangioma gene loci for families with inherited hemangioma are also planned. Identified hemangioma genes will be functionally tested for their ability to induce a cellular phenotype that is characteristic of hemangioma

endothelial cells when transfected into normal endothelial cells. The studies are expected to provide novel insights into mechanisms responsible for the formation of hemangiomas and increase the understanding of how endothelial cell behavior is regulated. This understanding forms the required basis for development of antiangiogenic therapies for cancer, rheumatoid arthritis and other major pathological conditions.

Project Title: MOLECULAR GENETICS OF INHERITED NEUROLOGICAL DISEASES Principal Investigator & Institution: Breakefield, Xandra O.; Professor; Massachusetts General Hospital 55 Fruit St Boston, Ma 02114 Timing: Fiscal Year 2002; Project Start 23-JAN-1987; Project End 31-AUG-2006 Summary: (provided by applicant) The goals of this Neurogenetics Center are to elucidate the molecular etiology and to ameliorate the course of hereditary tumors of the nervous system, in particular in neurofibromatosis type 2 (NF2) and tuberous sclerosis (TSC) This research will provide insight into the etiology of spontaneous neural tumors and mechanisms of growth regulation in the developing nervous system. The focus of the proposed studies is on understanding the genetic basis of functional changes in merlin (NF2), hamartin (TSC1) and tuberin (TSC2) and their role in formation and progression of meningiomas and other brain tumors. Elucidation of the cellular function of these proteins will be facilitated through identification and characterization of interacting proteins. Further, transgenic mouse models of these diseases will be used to understand physiologic changes associated with loss of these tumor suppressor genes and to provide a platform for therapeutic strategies.

Project Title: NATRIURETIC PEPTIDE INHIBITS VEGF SYNTHESIS AND ACTIONS Principal Investigator & Institution: Levin, Ellis R.; Professor; Medicine; University of California Irvine Irvine, Ca 926977600 Timing: Fiscal Year 2002; Project Start 01-AUG-1999; Project End 31-JUL-2004 Summary: Angiogenesis, or new blood vessel formation from existing vessels, is critical to normal development and wound healing, cancer metastases, diabetic proliferative retinopathy and hemangioma formation. Endothelial cell invasion of matrix, proliferation, and migration to sites of new vessel branching from existing vessels is regulated by factors, such as vascular endothelial cell growth factor (VEGF). We have recently found that the vasoactive proteins, the endothelins, stimulate VEGF transcription, synthesis, and secretion from cultured human vascular smooth muscle cells (VSMC). Further, we identified the natriuretic peptide (NP) family of vascular proteins as the first endogenous inhibitors of VEGF synthesis, and VEGF action. We propose to determine the proximal mechanisms by which these vasoactive peptides modulate VEGF synthesis in cultured human VSMC. We believe that endothelin-1 (ET1) triggers activation of Gq and Gi proteins leading to intracellular signal transduction culminating in ERK activation and VEGF transcription. NP inhibits this mainly through the clearance receptor, and a novel mechanism via the activation of RGS proteins or inhibition of G protein palmitoylation. We will measure each of these events and show modulation in response to ET, and by NP. The importance of G protein dynamics for NP-inhibition of ET-stimulated MAP-kinase (Erk) activity and VEGF transcription will be shown, linking these events. It is also possible that NP activate a MAP kinase related phosphatase, and we will determine if NP stimulate the synthesis and activity of MKP-1 and MKP-2, inhibited by ET-1. This would implicate this mechanism for the inactivation of ERK- signaling to VEGF transcription. We will then determine the signaling mechanisms by which VEGF stimulates EC proliferation, and the inhibition of this mechanism by ANP. This involves signaling through a novel ERK to JNK crossactivation cascade, which is inhibited by the NP, modulating specific cell cycle events such as cyclin D1 production and Cdk4 activation which are critical to G1/S progression in these cells. These will be shown by protein synthesis and kinase activity studies, in cells transfected with dominant negative SEK-1 (JNK kinase) and JNK-1, or PD98059 (Mek inhibitor).

Project Title: P3K, RETROVIRAL ONCOGENE AND HOMOLOG OF PI 3-KINASE Principal Investigator & Institution: Vogt, Peter K.; Member; Scripps Research Institute Tpc7 La Jolla, Ca 92037 Timing: Fiscal Year 2002; Project Start 10-SEP-1998; Project End 25-SEP-2003 Summary: The avian sarcoma virus ASV 16 contains a new oncogene, p3k, that is homologous to the gene encoding the catalytic subunit of PI 3-kinase. ASV 16 induces oncogenic transformation in chicken embryo fibroblast cultures and hemangiosarcomas in the animal. The work proposed in this application uses the retroviral vector RCAS to express and replicate various mutants of p3k and its targets. It will define the structural and functional consequences of the mutations that activate the oncogenic potential in viral p3k. It will also mark and characterize downstream targets of the viral P3k protein, tracing the signal via the cytoplasmic serine-threonine kinase Akt to genes that are differentially regulated and that determine the neoplastic phenotype of the p3ktransformed cells. A long range goal is to show that differential expression of key targets

accounts for the tumorigenic properties of the transformed cell. Angiogenesis is a critical factor in the development of p3k-induced hemangiosarcomas. It will be analyzed in vivo and in vitro. These experiments will seek to elucidate the mechanisms of p3k-induced angiogenesis, deciding between autocrine and paracrine stimulation and identifying angiogenic factors.

Project Title: PECAM-1 AND REGULATION OF ANGIOGENESIS Principal Investigator & Institution: Sheibani, Nader; Assistant Professor; Ophthalmology and Visual Sci; University of Wisconsin Madison 750 University Ave Madison, Wi 53706 Timing: Fiscal Year 2002; Project Start 15-SEP-1999; Project End 30-JUN-2004 Summary: (Adapted from Investigator's abstract): Angiogenesis, the highly regulated process of new capillary formation rarely occurs in normal adults, but is necessary during embryogenesis, corpus luteum formation, and wound healing. Uncontrolled angiogenesis plays an important role in diseases such as rheumatoid arthritis, hemangiomas, tumor growth and metastasis. Development of effective agents which can inhibit angiogenesis has potential value in the treatment of these diseases. Thrombospondin 1 (TS1) and certain peptides derived from TS I block angiogenesis in vivo and inhibit the proliferation and migration of endothelial cells (ECs) in vitro. These investigators have shown that TS I is a major regulator of EC phenotype and its expression is sufficient to restore a normal phenotype and suppress hemangioma formation in Polyoma middle T transformed mouse brain ECs. This is mediated, at least in part, by complete suppression of platelet endothelial cell adhesion molecule- I (PECAM-1) expression, an important regulator of EC adhesion and angiogenesis. The main objective of this proposal is to delineate the expression and adhesive function of different PECAM- I isoforms and to characterize their signaling pathways in ECs. The expression pattern of TS I and PECAM- I isoforms will be examined in ECs of developing murine blood vessels by in situ hybridization and immunohistochemistry. Expression of different PECAM- I isoforms and/or their cytoplasmic chimeras in ECs will determine whether different isoforms have distinct roles in regulation of EC phenotype and require interactions with cytoplasmic proteins. The GST-PECAM- I cytoplasmic fusion proteins phosphorylated on their tyrosine, serine, and threonine residues will be utilized in pull down experiments to identify the signal transducing molecules which interact with PECAM- 1. Expression of PECAM- I isoforms or his-myc tagged cytoplasmic domains in an epithelial cell model (MDCK cells), which forms adherens junctions very similar to ECs, will illustrate whether they affect formation of adherens junctions and influence PECAM- I cellular adhesive and signaling functions. These studies will provide insight into the coordinated expression of TS 1 and PECAM1 isoforms and their interactive roles in regulating EC phenotype. Characterization of the intracellular proteins which interact with PECAM- I cytoplasmic domains will provide further knowledge of the signaling pathways which regulate PECAM- I adhesive functions. It is suggested that a therapeutic benefit can be derived by exploiting these signaling pathways to control the hypervascularization characteristic of arthritis.

Hemangioma

Timing: Fiscal Year 2002; Project Start 01-JUL-2000; Project End 30-JUN-2004 Summary: Angiogenic endothelial cells are highly specialized for the purpose of forming capillaries de novo. As part of their unique activity, these cells express a cell membrane integrin, alpha-v-beta-3, that mediates endothelial cell-extracellular matrix interactions and is essential for the survival of the angiogenic endothelial cell. In malignancy, tumor growth and metastasis is directly correlated with the angiogenic process, stimulated by tumor- derived factors, andalpha-v-beta-3-expression is a consistent feature of the tumor neovasculature. Because expression of alpha-v-beta-3 is a ubiquitous surrogate marker for the presence of vascularizing metastatic foci, it is an ideal target for cancer therapy and is independent of a tumor's histologic derivation. In this proposal, we will develop a bifunctional fusion protein, mrIL-12vp, that will simultaneously target vascular and immune cell compartments within the tumor microenvironment. The fusion protein contains the small peptide sequence arginineglycine- aspartic acid (RGD), a ligand for alpha-v-beta-3 that will specifically direct it to angiogenic endothelium within the tumor microenvironment. Solubilized forms of small RGD-containing peptides are antagonistic to alpha-v-beta-3 expression and trigger endothelial cell apoptosis. This vascular homing peptide is coupled to interleukin-12 (IL12), a cytokine with promising antiangiogenic activity mediated by induction of interferon-gamma and antiangiogenic chemokines. IL-12 is also inhibitory to the production of VEGF and MMP, key factors in the angiogenic process. As a result of targeting by the RGD component, high intratumoral concentrations of IL-12 are anticipated that will also serve to activate tumoricidal responses of immune cells in situ. Experiments will be conducted in tumor-bearing mice designed to demonstrate homing of the fusion protein, localization of IL-12 within the tumor microenvironment, effects on tumor vascularization and growth, contribution of immune cells, and the role of the homing peptide in mediating antiangiogenic properties of this fusion protein. The approach proposed for simultaneously targeting vascular and immune cell compartments within the tumor microenvironment offers an opportunity to develop an innovative strategy to address the significant problems associated with tumor angiogenesis and cytokine therapy.

Project Title: PERIORBITAL HEMANGIOMA--A MODEL FOR ANGIOGENESIS Principal Investigator & Institution: Ritter, Matthew R.; Scripps Research Institute Tpc7 La Jolla, Ca 92037 Timing: Fiscal Year 2002; Project Start 30-SEP-2002 Summary: (From the Applicant?s Abstract): The long-term objectives of this proposal are to gain a better understanding of the mechanisms of angiogenesis through the study of periorbital hemangiomas, to design new treatments for theses tumors based on their biological characteristics, and to apply these findings to the study of ocular angiogenesis. Hemangiomas are vascular tumors that grow rapidly and then undergo spontaneous involution. Thus this tumor represents an excellent model to study proliferative and involutional phases of angiogenesis; insight gained into mechanism should be applicable to understanding and developing treatments for neovascular eye diseases in general, the leading causes of visual loss in Americans. These tumors frequently occur periorbitally and threaten vision, giving a second level of relevance to the eye. We will use multiphoton confocal microscopy to study integrin expression in human hemangioma specimens. An animal model of hemangioma has been established and will allow us to test new approaches to the treatment of these lesions. While in vitro investigations will determine, at the molecular level, the role of integrins in

Project Title: PHYSIOLOGY OF THYROID HORMONE DEPENDENT GENE EXPRESSION Principal Investigator & Institution: Larsen, Philip R.; Professor; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 15-JAN-1992; Project End 31-MAR-2006 Summary: (Scanned from the applicant's abstract) Our laboratory has focused on the mechanisms regulating triiodothyronine (T3) homeostasis for over 25 years. Critical to this process are the actions of the iodothyronine deiodinases which function in concert to regulate thyroxine (T4) activation and the inactivation of T4 and T3. This proposal continues this theme. In the first Specific Aim we will continue our investigations of a cell type specific negative thyroid hormone response element (nTRE) in the promoter of the human Type 1 deiodinase (Dl) gene. This thyroid receptor (TR) binding sequence also binds a novel JEG cell transcription factor (JTF) with high affinity and specificity. JTF increases expression of genes containing this sequence and this effect is enhanced by APO-TRs. T3 eliminates this effect. Using DNA affinity matrix techniques we will isolate and identify this newly discovered protein and determine how TR cooperates with it as an example of a specific mechanism for negative regulation of gene expression by thyroid hormone. Uncontrolled, rapid inactivation of thyroid hormone causes hypothyroidism in a syndrome which we recently identified in infants with large hemangiomas. Infantile hemangiomas express Type 3 iodothyronine deiodinase (D3), the major physiological inactivator of 13 and 14, at levels up to 8-fold that in placenta. Large tumors can deiodinate T4 and T3 more rapidly than the infant's thyroid can secrete them. Specific Aim 2 will elucidate the mechanism for ectopic expression of D3 in these tumors. We will compare hemangioma-derived and normal human capillary endothelial cells to discover pathways which could activate D3 expression analogous to those in placenta. Specific Aim III is to define the mechanism for the myocardial response of the euthyroid heart to the thyrotoxic state such as occurs in patients with hyperthyroidism. We have developed a novel method for inducing chronic myocardial thyrotoxicosis in mice by use of a transgene in which Type 2 iodothyronine deiodinase (D2) is driven by the alpha-MHC promoter. We will first define the mechanism for the two-fold increase in the cAMP response to forskolin in myocardial membranes from these transgenic mice. We will also document the differences n gene expression profiles between euthyroid and thyrotoxic myocardium from both young and old mice. Only a few genes have been identified which increase their expression significantly between the euthyroid and hyperthyroid state. Identifying such genes in the myocardium will be especially critical to the understanding of the effects of T3 excess on the heart in human hyperthyroidism. These studies will provide new information relevant to both basic and clinical thyroid physiology. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

STEM

CELL

Principal Investigator & Institution: Yu, Ying; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2004 Summary: This project aims to provide insight into the poorly understood cellular and molecular mechanisms underlying the involution of infantile hemangioma. Hemangiomas are the most common vascular tumors of infancy affecting 5-10% of children. The vast majority of these tumors occur in the skin. Hemangioma is characterized by an initial phase of rapid growth during infancy and subsequent spontaneous involution in early childhood (1). Histopathologically, robust angiogenesis highlights the proliferative phase (2). Apoptosis of endothelial cells and marked accumulation of adipocytes occurs during involution (3). Strikingly, in the final involuted stage, hemangioma appears as all fibrofatty tissue. This fibrofatty tissue is often disfiguring such that plastic surgery is required. Current therapies are largely nonspecific and somewhat inadequate. Clearly, identifying regulators that accelerate the normal involution process and/or prevent growth of hemangioma may provide effective therapies. Previously, we have shown that hemangioma-derived endothelial cells (Hem-ECs) are clonal and exhibit abnormal behavior in vitro (4,5). This suggests that hemagioma arises from clonal expansion of a single endothelial cell (the "tumor" cell). Identification of somatic mutation(s) in Hem-ECs as the cause of hemangioma is currently underway. Recently, we have isolated mesenchymal. Recently, we have isolated mesenchymal stem cells (MSCs) from hemangiomas. Human MSCs can differentiate into multiple lineages including adipocytes (6). These hemangiomasderived MSCs (Hem-MSCs) are not clonal, suggesting they are not the "tumor cells", but the stromal element. In preliminary data, we showed that conditioned medium extracted from fresh hemangioma tissue can induce the adipogenic differentiation of Hem-MSCs in vitro. Taken together, we have identified a novel cellular component of hemangioma that may play a significant role in the involution of hemangioma. We hypothesize that hemangioma ECs contribute to the recruitment of MSCs from surrounding skin tissue or blood circulation and subsequently, induce differentiation of MSCs into adipocytes in the tumor. This hypothesis is difficult to address in vivo due to the lack of an available animal model. However, the Hem-ECs and Hem-MSCs that we have developed in culture will allow us to study the tumor and stromal cell interactions. Specifically, we propose, using a co-culture system, to investigate the role of soluble factors secreted from Hem-ECs and cell-cell contacts between the two cell types in mediating the migration and adipogenic differentiation of Hem-MSCs. Specific Aims: 1. To test the hypothesis that Hem-ECs secrete factors to mediate the migration of HemMSCs. 2. To test the hypothesis that Hem-ECs mediate the adipogenic differentiation of Hem-MSCs. 3. To identify the molecular targets that regulate the migration and differentiation of Hem-MSCs.

Principal Investigator & Institution: Huang, Stephen A.; Children's Hospital (Boston) Boston, Ma 021155737 Timing: Fiscal Year 2002; Project Start 15-JUL-2002; Project End 30-JUN-2007 Summary: (provided by applicant): Hemangiomas are the most common tumor of infancy, with a prevalence of 5-10% at one year of age. We recently discovered a previously unrecognized association between hypothyroidism and infantile hemangiomas, due to the expression of type 3 iodothyronine deiodinase (D3) in these tumors. This research grew out of our clinical observations of an infant seen in the first year of my endocrinology fellowship. D3 is a selenoenzyme normally present in the brain and placenta as the physiologic inactivator of thyroxine and triiodothyronine. Extremely high levels of D3 activity are present in proliferative hemangioma tissue, causing the rapid inactivation of thyroid hormone. In the case of children with high tumor burden, severe hypothyroidism can develop due to the inability of the infant's thyroid to secrete hormone faster than it is inactivated by the tumor. Since the publication of these findings, several additional children have been diagnosed and three other institutions have published reports of infants with hepatic hemangiomas and acquired hypothyroidism. We have termed this condition "consumptive hypothyroidism." The goals of this proposal are to determine the clinical consequences of D3 expression in hemangiomas and characterize the molecular mechanism(s) for its expression. The large population of hemangioma patients seen by the Vascular Anomalies Center of Children's Hospital Boston will be studied prospectively to determine the incidence of this endocrinopathy and the optimal means of treating their thyroid dysfunction. Patient specimens will be analyzed by immunohistochemistry using two newly generated D3 antibodies. Human endothelial cells have been successfully cultured from surgical specimens and will be used as a model to study the transcription regulation of D3. Under the mentorship of Dr. P. Reed Larsen, the candidate will receive training in molecular biology and clinical thyroidology with the goal of becoming an independent investigator and an expert in the management of pediatric thyroid disease.

anomalies. Clinical research will focus on etiologic aspects of these diseases, especially genetic aspects. Trainees will be involved with study design, data collection and data analysis. The principal investigator is actively involved in investigations of potential genetic implications of these entities in collaboration with Douglas Marchuk, PhD., of the Department of Human Genetics at Duke University. Preliminary studies have focused on somatic and/or germline mutations as possible etiologic factors in vascular anomalies. We are performing genetic linkage analysis in affected kindreds with positional cloning of potential candidate genes, and we are assessing loss of heterozygosity in hemangioma tissue to see if endothelial cells in hemangioma tissue is clonal. In collaboration with Dr. Marchuk's group, the principal investigator recently published a familial incidence of hemangiomas, and genetic linkage to chromosome 5q in some of these families. The long-term objectives of this project are to establish a mentorship program in clinical investigation of vascular anomalies pursuing the clinical investigation of a potential genetic basis for the development of hemangiomas and vascular malformations in collaboration with an established investigator in this field.

CHAPTER 2. NUTRITION AND HEMANGIOMA Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and hemangioma.

Finding Nutrition Studies on Hemangioma 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 “hemangioma” (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.

CHAPTER 3. CLINICAL TRIALS AND HEMANGIOMA Overview In this chapter, we will show you how to keep informed of the latest clinical trials concerning hemangioma.

Recent Trials on Hemangioma The following is a list of recent trials dedicated to hemangioma.8 Further information on a trial is available at the Web site indicated. •

Direct Injection of Alcohol for the Treatment of Spinal Tumors Condition(s): Hemangioma; Neoplasm Metastasis; Spinal Neoplasm Study Status: This study is completed. Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) Purpose - Excerpt: Tumors of the spine can be described as primary, meaning that the tumor originated from cells normally found in the spine, or metastatic, cells from another area of the body that have spread to the spine. Metastatic tumors are more common than primary tumors. Tumors of the spine can press against the spinal cord and interfere with information traveling down from the brain to the nerves of the spinal cord. As a result, patients with spinal tumors can suffer from loss of movement and sensation within areas of the body below the tumor. In addition, tumors of the spine are typically painful conditions. Presently, the treatment of choice for spinal tumors is radiation therapy. However, many tumors of the spine become resistant to radiation therapy. In addition, because the spinal cord is often so close to the tumor it can be damaged by the radiation. Absolute (100%) ethanol is commonly known as "alcohol". It is the same kind of alcohol found in alcoholic beverages. When pure alcohol is injected directly into a tumor it can destroy cells and blood vessels. Because of this feature, researchers would like to test the effectiveness of alcohol in treating patients with spinal tumors. Researchers believe that intratumoral ethanol injection is a treatment worth studying more closely because it is minimally invasive, has been proven to be an effective treatment for other types of metastatic tumors, can be used repeatedly, and

CHAPTER 4. PATENTS ON HEMANGIOMA 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 “hemangioma” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on hemangioma, we have not necessarily excluded nonmedical patents in this bibliography.

Patents on Hemangioma By performing a patent search focusing on hemangioma, 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. The following is an 9Adapted

Compounds for the treatment of disorders related to vasculogenesis and/or angiogenesis Inventor(s): App; Harald (Hillsborough, CA), Gazit; Aviv (Jerusalem, IL), Levitzki; Alexander (Patomic, MA), McMahon; Gerald M. (San Francisco, CA), Tang; Peng Cho (Moraga, CA) Assignee(s): Sugen (redwood City, Ca), Yissum Research Development Corp. (jerusalem, Il) Patent Number: 5,712,395 Date filed: February 9, 1995 Abstract: The present invention relates to organic molecules capable of modulating tyrosine kinase signal transduction and particularly KDR/FLK-1 receptor signal transduction in order to regulate and/or modulate vasculogenesis and angiogenesis. The invention is based, in part, on the demonstration that KDR/FLK-1 tyrosine kinase receptor expression is associated with endothelial cells and the identification of vascular endothelial growth factor (VEGF) as the high affinity ligand of FLK-1. These results indicate a major role for KDR/FLK-1 in the signaling system during vasculogenesis and angiogenesis. Engineering of host cells that express FLK-1 and the uses of expressed FLK-1 to evaluate and screen for drugs and analogs of VEGF involved in FLK-1 modulation by either agonist or antagonist activities is also described.The invention also relates to the use of the disclosed compounds in the treatment of disorders, including cancer, diabetes, hemangioma and Kaposi's sarcoma, which are related to vasculogenesis and angiogenesis. Excerpt(s): The present invention relates to novel compounds capable of modulating and/or regulating tyrosine kinase signal transduction. The Applicants have demonstrated that the murine fetal liver kinase 1 (FLK-1) receptor and its non-murine counterparts, including the human Kinase Insert-Domain-Containing Receptor (KDR), play a major role in a tyrosine kinase signal transduction system. Polypeptide growth factors such as vascular endothelial growth factor (VEGF) having a high affinity to the KDR/FLK-1 receptor have been associated with the proliferation of endothelial cells and more particularly vasculogenesis and/or angiogenesis. Consequently, compounds affecting the enzymatic function of the KDR/FLK-1 receptor may be used to not only regulate, modulate and/or inhibit the tyrosine kinase signal transduction system, but also the proliferation of endothelial cells in processes such as vasculogenesis and/or angiogeneis. The present invention is therefore further directed to the use of compounds which bind to and/or modulate the activity of the receptors comprising the tyrosine signal transduction system, and more specifically the KDR/FLK-1 receptor, to treat disorders related to vasculogenesis and/or angiogenesis. Receptor Tyrosine Kinases. Receptor tyrosine kinases (RTKs) comprise a large family of transmembrane receptors for polypeptide growth factors with diverse biological activities. The intrinsic function of RTKs is activated upon ligand binding, which results in phosphorylation of the receptor and multiple cellular substrates, and subsequently in a variety of cellular responses. Ullrich & Schlessinger, 1990, Cell 61:203-212. As has been reported by the inventors, RTKs, as well as, more generally, protein tyrosine kinases, play an important role in the control of cell growth and differentiation (for review, see Schlessinger & Ullrich, 1992, Neuron 9:383-391). Aberrant expression or mutations in the RTKs have been shown to lead to either uncontrolled cell proliferation (e.g. malignant tumor

Patents 73

growth) or to defects in key developmental processes. Consequently, the biomedical community has expended significant resources to discover the specific biological role of members of the RTK family, their function in differentiation processes, their involvement in tumorigenesis and in other diseases, the biochemical mechanisms underlying their signal transduction pathways activated upon ligand stimulation and the development of novel antineoplastic drugs.

Control for laser hemangioma treatment system Inventor(s): Muckerheide; Myron C. (Schofield, WI) Assignee(s): Maun; Lorenzo P. (belleville, Il) Patent Number: 4,316,467 Date filed: June 23, 1980 Abstract: A laser for directing a nominally 5 micron wavelength beam at a hemangioma or other variegated lesion. A fiber optic bundle for intercepting radiation reflected from the lesion at an intensity corresponding with the color intensity of the region at which the beam is directed. The output beam from the fiber optic bundle modulates a photodetector stage whose amplified output drives a galvanometer. The galvanometer shaft is coupled to the shaft of a potentiometer which is adjustable to regulate the laser power supply and, hence, the laser output energy level so laser beam energy is reduced when high absorption regions in the lesion are being scanned by the beam and increased as low absorption regions are being scanned. Excerpt(s): This invention relates to apparatus for laser treatment of hemangiomas, commonly called portwine birthmarks or lesions, on the skin of human patients. Inducing coagulation necrosis and eradication of a portwine mark on the skin of a patient by projecting a laser beam onto the mark is becoming a more widespread practice among plastic and reconstructive surgeons. Portwine lesions have color variations in the range of pink to dark bluish-red. Lasers such as the argon laser which produce coherent light in the blue-green part of the spectrum are usually used for treatment. The output beam from an argon laser lies in the blue-green wave length range of 4.9 to 5.1 microns as is well-known. Radiation in this wavelength range is differentially absorbed in a portwine lesion in correspondence with the degree of redness or darkness in the area increments of the lesion. When the bluish laser beam strikes a non-reddish area such as skin surrounding the hemangioma, a large amount of energy in the form of light is reflected but when the beam impinges upon deep purple or various shades of reddish purple which occur in the hemangioma, the laser light energy is heavily absorbed. Zones in the hemangioma which have been fully treated with the laser beam turn lighter or whiter than adjacent incompletely treated regions. Usually, the laser beam spot is focused to a diameter of 2 or 3 mm. Laser beam energy in the range of 1 to 4 watts has been found suitable for treating hemangiomas and similar colored lesions. As the surgeon scans the beam spot over the lesion, various degrees of redness or darkness are encountered. When a dark zone is encountered, the surgeon wants to reduce the laser output power to avoid overtreatment since the laser energy is heavily absorbed in dark zones. Moreover, as the surgeon progresses from light to dark and dark to light zones with various shades in between, it has been necessary for the surgeon to repeatedly adjust laser power output to obtain the appropriate amount of energy for inducing necrosis but without undertreatment or overtreatment. Because the surgeon must wear highly pigmented orange protective eyeglasses to prevent the bluish

74

Hemangioma

argon beam from damaging his own eyes, he cannot actually see the laser beam spot although he can detect the color change in any zone that has been treated. A further problem is that the surgeon cannot adjust the laser power output indicating meter properly to the many shades of color in the lesion which can be randomly distributed. The human eye can discriminate color and shade, but cannot do so rapidly enough to enable the surgeon to make corrective adjustments of the power output of the laser as is required as the beam spot is being scanned.

Device and method for underskin laser treatments Inventor(s): Del Giglio; Antonio (Verona, IT) Assignee(s): Ceramoptec Industries, Inc. (east Longmeadow, Ma) Patent Number: 6,200,332 Date filed: July 9, 1999 Abstract: A device and method for underskin laser treatment that is minimally invasive, versatile and precise, that allows for underskin laser treatment with only minimal insertions into the area of treatment. For example, an entire area may be treated with one insertion. The device and method incorporates a standard insertion component making the system inexpensive and easy for doctors to use. In addition, the the invention allows users to get in direct contact with the treatment site, eliminating deleterious side effects encountered when treatment is administered to the skin surface. The device and method has applications in several areas of treatment. First, underskin treatment of aesthetic skin blemishes such as sagging and wrinkles can be performed with minimal external effects. Laser power is delivered directly beneath the skin, bypassing harmful exposure of the skin surface to the radiation. Second, common vascular abnormalities such as capillary disorders, spider nevus, hemangioma, and varicose veins can be selectively eliminated. The device allows a simple, single insertion per treated structure and specific laser delivery. The needle is inserted into the vascular structure and any abnormalities are eradicated starting from the source and continuing through the entire structure. Third, when coupled with x-ray imaging, the present invention may be used to treat various internal body structures for example during surgery. X-ray imaging allows the user to orient the device within the body structures. Laser delivery treatment can then be administered as described above. Excerpt(s): Underskin laser treatment is an effective way to eliminate many abnormalities. A below the skin application provides a more proximal access to the area of treatment enabling the use of a less powerful and less harmful laser. Straight form surface treatments require laser energy to be focused on the skin surface, commonly leading to undesired side effects such as external discoloration or scarring. The present invention describes an underskin laser treatment system that can be utilized for correcting skin irregularities, eradicating vascular abnormalities, and operating in various parts of the body. Radiation administered below the surface of the skin provides a more proximal application with reduced risks of accidentally exposing surrounding tissue to the laser radiation. The present invention describes an improved method of wrinkle removal. By allowing laser energy to be delivered subcutaneously, the present invention substantially prevents against surface epidermal injury. Further, the closer proximity of the application of the radiation to the underskin site allows a lower power application reducing the amount of deleterious side effects in general. Laser treatment below the surface of the skin has also been described in U.S. Pat. No. 5,531,739 to Trelles.

Patents 75

There a method is described whereby an optical probe is inserted into the skin adjacent to a vascular abnormality. Introducing laser pulses will serve to collapse and close off the vein. This method requires multiple insertions of the device along the desired vein to treat the abnormality. The procedure has limitations. First, the described method is specific for treatment of veins, primarily in the leg, and is therefore limited to that specific treatment. Second, the procedure requires a low power beam to illuminate and direct the probe to the treatment site under the skin. Treatment is then limited to underskin sites at a depth that the illumination beam can penetrate. Third, the method describes delivery of the laser power to the vicinity of, and outside the vein requiring treatment. Such laser treatment closes off the vein by collapsing its wall, an indirect solution. Web site: http://www.delphion.com/details?pn=US06200332__ •

DNA encoding HEM-1, a gene expressed by sclerosing hemangioma cells Inventor(s): Kumar; Rajiv (Rochester, MN) Assignee(s): Mayo Foundation for Medical Education and Research (rochester, Mn) Patent Number: 5,618,695 Date filed: June 7, 1995 Abstract: An isolated and purified DNA sequence encoding hemangioma factor-1 is provided. A host cell transformed with a DNA sequence encoding hemangioma factor-1 and a method of introducing and expressing the DNA sequence in a host cell is also provided. A further embodiment of the invention is an expression cassette comprising the isolated and purified DNA sequence encoding hemangioma factor-1. Excerpt(s): Phosphorus plays an important role in normal human physiology. It is a constituent of nucleic acids, phospholipids, high energy intermediates, and hydroxyapatite which in turn is the major component of bone mineral. Phosphorus is absorbed by and secreted into the intestine, and inorganic phosphates are filtered by the renal glomerulus and reabsorbed by the proximal tubule of the kidney. Thus, the intestine and kidney play key roles in controlling phosphorus homeostasis. Several factors alter the efficiency with which the intestine and kidney absorb or reabsorb phosphorus. Important among these are the amount of phosphorus ingested in the diet and the rate of sodium reabsorption in the proximal tubule. Hormones such as 1,25dihydroxyvitamin D.sub.3, parathyroid hormone (PTH), growth hormone, insulin-like growth factor and insulin alter the efficiency of phosphate retention in the organism by acting on intestinal or renal epithelia. The effects of 1,25-dihydroxyvitamin D.sub.3, and parathyroid hormone, however, are primarily on calcium absorption whereas the effects of growth hormone, insulin-like growth factor and insulin are primarily on anabolic phenomena, cell growth and glucose metabolism. Clearly, the ability of the organism to control phosphorus balance independent of calcium balance would be of biological and homeostatic advantage. A factor (or factors) that specifically alters phosphorus metabolism independent of changes in other metabolic pathways has not been characterized. Cai et al. (New Eng. J. Med., 330, 1645 (1994)) described the presence of a heat labile, 8,000-25,000 dalton, inhibitor of renal epithelial cell sodium-dependent phosphate transport in supernatants of cultured sclerosing hemangioma cells. These cells were derived from a tumor of a patient with oncogenic osteomalacia and hypophosphatemia. The patient's hypophosphatemia and urinary phosphate wasting were cured upon removal of the tumor. The factor(s) specifically inhibited renal epithelial phosphate transport but not glucose or alanine transport. Supernatants from

these tumor cells also contained a substance that cross-reacted with PTH-like antisera but not PTH-related antisera. The mechanism of action of the factor(s) was distinct from that of PTH because the factor(s) inhibited phosphate transport in renal epithelial cells without increasing cAMP concentrations and its action was not blocked by a PTH antagonist. parathyroid hormone antibodies. However, the factor was not further characterized. Web site: http://www.delphion.com/details?pn=US05618695__ •

Hemangioma treatment method Inventor(s): Derkach; Vladimir Y. (Leningrad, SU), Granov; anatoly M. (Leningrad, SU), Polysalov; Vladimir N. (Leningrad, SU) Assignee(s): Ferrotherm International, Inc. (denver, Co) Patent Number: 5,108,359 Date filed: December 17, 1990 Abstract: The subject of this invention is in the field of medicine, particularly surgery, and is intended for the treatment of benign tumors and angiomas. A hemangioma is an angioma, or tumor, formed by an anomalous proliferation of vascular endothelium, forming an undesirable mass, which can occur anywhere in the body. The resulting disease is known as hemangiomatosis. The method of this invention is comprised of a reduction of the arterial blood flow to the hemangioma which limits the blood circulation in the tumor mass, thus creating favorable conditions for subsequent ferromagnetic embolization from externally and selectively applied electromagnetic or ultrasound energy and sclerotization of the tumor tissue, preventing the spread of ferromagnetic particles through the vessels and into other organs and systems. At the same time, maintaining the blood flow, though reduced, prevents the development of a total necrosis due to acute impairment of the tumor's blood circulation, which significantly reduces the general toxic effect. The reduced blood stream still leaves the possibility of introducing medication into the tumor, which reduces the possibility of complications during the postembolization period. Excerpt(s): The subject of this invention is in the field of medicine, particularly surgery, and is intended for the treatment of benign tumors and angiomas. An hemangioma is an angioma, or tumor, formed by an anomalous proliferation of vascular endothelium, forming an undesirable mass, which can occur anywhere in the body. The resulting disease is known as hemangiomatosis. At the present time the main methods of hemangioma treatment include surgical management, radiation therapy, physical influence from the effects of electromagnetic waves (in ranges including low, high, ultrahigh, and super high frequencies), cryotherapy or hyperthermia, and chemical treatment consisting of sclerotherapy using irritating agents. Sclerotherapy as a method of tumor treatment is used mainly for external angiomas, located on the extremities of the body (head, neck, face, lips) and includes the introduction into angioma's lacunae of such chemical agents as 60 percent glucose solution, 76-96 percent ethyl alcohol, 1-3 percent sotradecol, and sclerovein.

Transformation of unwanted tissue by deep laser heating of water Inventor(s): Tankovich; Nikolai (San Diego, CA) Assignee(s): Lumedics, Ltd. (san Diego, Ca) Patent Number: 5,897,549 Date filed: July 11, 1996 Abstract: A process for treating relatively deep formations of undesirable sub-epidermal tissue by heating water in the formations with a laser to denature proteins therein. In an exemplary embodiment, a laser beam is operated to irradiate a target region of highly vascularized dermal tissue in a blood-circulating living being, such as a human. The laser light preferably has a wavelength of about 1.45-1.68.mu.m. This operating parameter provides the laser beam with a low enough water absorption coefficient to facilitate adequate penetration in to the target area while still providing enough energy to heat water to a temperature capable of spatially conforming vascularized tissue in the target area. Treatment pursuant to the invention may be applied to highly vascular regions of sub-epidermal tissue (such as strawberry hemangioma, spider veins, telangiectasia, karposi's sarcoma, and the like), as well as regions of dermis collagen mechanically damaged due to various reasons (such as frequent muscular contraction, burning, traumatic irritation, worsening of mechanical damage due to environmental exposure, etc.). Excerpt(s): The present invention relates to the use of lasers to transform undesirable sub-surface tissue in a living being, such as a human. More particularly, the invention concerns a method for transforming relatively deep sub-epidermal formations of undesirable tissue by heating water in the formations with a laser. This causes protein denaturing such as spatial protein conformation, without excessively damaging the unwanted tissue. In the field of cosmetic surgery, one important concern is the treatment of highly vascularized tissues, such as capillary blood vessels, strawberry hemangiomas, spider veins, telangiectasia, and the like. In this respect, many known techniques are aimed at eliminating or reducing such tissue. Some of these techniques, for example, include surgical dissection, sclerotherapy, and electro-cuttering. With surgical dissection, the patient is first anesthetized and then a cutting device such as a scalpel is used to surgically remove the vascularized tissue. With sclerotherapy, an alcohol-based substance is injected into veins for clotting of the veins. With electrocuttering, a high-voltage scalpel is used to effectively "cut out" the unwanted tissue while coagulating blood in the region. Usually, healing of the treated tissue occurs after formation of a lesion on the skin's surface at the treatment site. Although these techniques may be satisfactory in some applications, they may prove inadequate in certain other circumstances. For instance, certain patients may object to the pain caused by these procedures. Additionally, some patients may experience excessive bleeding, internally and/or externally. Furthermore, these procedures may inflame the treated tissue in some cases, and lead to healing by second tension. Another potential drawback of known methods concerns the post-treatment healing time, which some may find excessive. Further, in certain cases these techniques have been known to leave scars or other noticeable marks. Although sclerotherapy may be effective for treating big veins, some may complain that sclerotherapy is not sufficiently effective for smaller vessels such as capillary blood vessels.

Curcumin and curcuminoid inhibition of angiogenesis Inventor(s): Arbiser, Jack L.; (Atlanta, GA) Correspondence: Patrea L. Pabst; Holland & Knight Llp; Suite 2000, One Atlantic Center; 1201 West Peachtree Street, N.E.; Atlanta; GA; 30309-3400; US Patent Application Number: 20010025034 Date filed: January 18, 2001 Abstract: Methods for treating diseases or disorders of the skin which are characterized by angiogenesis have been developed using curcumin and curcumin analogs. Based on the results obtained with curcumin, it has been determined that other angiogenesis inhibitors can also be used to treat these skin disorders. It has further been discovered that curcumin acts to inhibit angiogenesis in part by inhibition of basic fibroblast growth

factor (bFGF), and thereby provides a means for treating other disorders characterized by elevated levels of bFGF, such as bladder cancer, using curcumin and other analogues which also inhibit bFGF. Representative skin disorders to be treated include the malignant diseases angiosarcoma, hemangioendothelioma, basal cell carcinoma, squamous cell carcinoma, malignant melanoma and Karposi's sarcoma, and the nonmalignant diseases or conditions including psoriasis, lymphangiogenesis, hemangioma of childhood, Sturge-Weber syndrome, verruca vulgaris, neurofibromatosis, tuberous sclerosis, pyogenic granulomas, recessive dystrophic epidermolysis bullosa, venous ulcers, acne, rosacea, eczema, molluscum contagious, seborrheic keratosis, and actinic keratosis. Excerpt(s): The invention is generally in the field of methods of inhibiting angiogenesis, and more specifically is drawn to methods and compositions for inhibiting angiogenesis. Current treatments of cancer and related diseases have limited effectiveness and numerous serious unintended effects. Based primarily on chemical, radiation and surgical therapy, these treatments have progressed only incrementally during more than thirty years of intensive research to discover the origins and devise improved therapies of neoplastic diseases. Current research strategies emphasize the search for effective therapeutic modes with less risk, including the use of natural products and biological agents. This change in emphasis has been stimulated by the fact that many of the consequences, to patients and their offspring, of conventional cancer treatment, including new cancers, mutations and congenital defects, result from their actions on genetic material and mechanisms. Hong et al., J. Natl. Cancer Inst. Monogr. 17:49-53 (1995). Efforts continue to discover the origins of cancer at the genetic level, and correspondingly new treatments, but such interventions also may have serious unanticipated effects.

disease (Boring, et al., (1993) CA Cancer J. Clin. 43:7). Cancer is characterized primarily by an increase in the number of abnormal, or neoplastic, cells derived from a normal tissue which proliferate to form a tumor mass, the invasion of adjacent tissues by these neoplastic tumor cells, and the generation of malignant cells which spread via the blood or lymphatic system to regional lymph nodes and to distant sites. The latter progression to malignancy is referred to as metastasis. The switch in tumors from the quiescent state to malignancy is signaled by the commencement of the angiogenesis process. Tumors need an extensive network of capillaries to provide nutrients and oxygen. Solid tumors will not grow beyond 2 millimeters without new blood vessels. Malignancy and invasion are angiogenesis dependent. The concept behind angiogenesis is simple: tumors must build new blood vessels to enhance the delivery of vital nutrients that allow them to grow and spread. As with many facets of cancer, angiogenesis plays a role in normal cellular growth and maturation. Capillaries grow when and where they are needed--during the development of a fetus, for example--and don't usually grow when they are not required. Normal tissues have an intricate system which controls when to turn angiogenesis on or off. Tumor cells are able to override this system and turn on the growth of blood vessels, which in turn allow the tumor to grow from a bundle of a few mutated cells into a tumor mass, that has the capability to metastasize and kill.

ISBN: 0443055203. Summary: This chapter on hepatic tumors (benign and malignant) is from a comprehensive handbook in outline format that offers easy access to information on the full range of liver disorders and covers symptoms, signs, differential diagnoses, and treatments. Hemangioma of the liver is found in up to 1 percent of the normal population and is rarely of clinical consequence. Other benign tumors of the liver, including hepatic adenoma, are rare. Hepatic adenoma usually requires surgical resection because of the risks of rupture and the development of malignancy. In the presence of cirrhosis, hepatocellular carcinoma (HCC) accounts for approximately 75 percent of all liver tumors. The most important risk factors for development of HCC are cirrhosis and chronic hepatitis B virus, and hepatitis C virus infection. Although surgical resection or liver transplantation offers the best chance of curing HCC, few patients are suitable for surgery. Cholangiocarcinoma (CCC) is not usually associated with cirrhosis; CCC of the central type is often associated with primary sclerosing cholangitis and has a poor prognosis. 3 figures. 4 tables. 10 references.

They emphasize that histopathologic examination is always necessary to establish the correct diagnosis. Specific processes discussed include fibroma or focal fibrous hyperplasia, calcifying fibroblastic granuloma, pyogenic granuloma, peripheral giant cell granuloma, periapical cemental dysplasia, hemangioma, nevus, papilloma, verruca vulgaris, peripheral odontogenic tumors, ameloblastoma, squamous odontogenic tumor, benign cementoblastoma, squamous cell carcinoma, metastasis to the gingiva, Kaposi's sarcoma, malignant lymphoma, osteosarcoma, Langerhans cell disease, gingival cyst, lateral periodontal cyst, inflammatory paradental cyst, odontogenic keratocyst, and radicular cyst. For each process, the authors cover clinical features, histopathology, and treatment. Full-color photographs, radiographs, and photomicrographs illustrate the chapter. 26 figures. 48 references.

PRICE: $395.00 plus shipping and handling. ISBN: 0070219435. Summary: This chapter provides health professionals with a clinical rationale for choosing specific laser therapies in dermatology. The chapter begins with a discussion of the optics of the skin. Absorption and scattering determine the penetration of light into skin. The chapter continues by describing laser-skin interactions, including photothermal effects, photochemical effects, and photomechanical effects. Thermal effects on tissue are both time and temperature dependent. Photothermal interactions include vaporization and selective photothermolysis. Photochemical interactions related to dermatology include both native photobiologic responses to ultraviolet radiation and photosensitizer-induced responses. Photomechanical injury is characterized by disruption of organelles, membranes, and cells. The chapter then addresses the issue of laser safety. The principles of laser safety focus on the maintenance of a safe environment and protection of the patient, surgeon, and surgical staff. Biological hazards include risks to the ocular, respiratory, and skin regions and also risk of transmission of infection. The remainder of the chapter discusses the use of laser treatment for various lesions. Laser treatment of postinflammatory pigmentation has been disappointing, and laser treatment for melasma generally cannot be recommended because of the expense and risk of side effects. However, lasers may be used to treat vascular lesions such as portwine stains, strawberry hemangioma, essential telangiectasias, and phlebectasias; pigmented lesions such as cafe au lait macules; dermal melanocytoses such as nevus of Ota; nevomelanocytic lesions; Becker's nevus; nevus spilus; and epidermal nevi. Lasers can also be used to remove tattoos and hair, create recipient sites for hair transplant grafts, and resurface photodamaged and acnedamaged skin. The chapter discusses laser skin resurfacing in terms of indications and contraindications, patient selection, laser method, perioperative and anesthesia considerations, safety, anesthesia requirements, effectiveness, side effects, mechanisms of action, and recent advances. 8 figures, 1 table, and 58 references. •

Summary: With increasing use of imaging modalities for evaluation of various abdominal conditions, more liver masses are being recognized. These lesions may be small or large and may or may not be the cause of the patient's symptoms. Although most of the incidentally noted masses are benign, a definitive diagnosis has to be established to reassure the patient and also to be certain that a radiologically observed lesion is not malignant. This chapter is devoted to the most common liver masses found in clinical practice and the advantages and disadvantages of the various diagnostic modalities. The chapter 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 cavernosa hemangioma, focal nodular hyperplasia, nodular regenerative hyperplasia, hepatic adenoma, cystic lesions, hemangioendothelioma,

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 Hemangioma In the following section, we will discuss databases and references which relate to the Genome Project and hemangioma. 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.

To access the Entrez system at the National Center for Biotechnology Information, go to http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?CMD=search&DB=genome, and then select the database that you would like to search. The databases available are listed in the drop box next to “Search.” Enter “hemangioma” (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.

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 hemangioma 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 hemangioma. 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 hemangioma. 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 “hemangioma”:

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 hemangioma. 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.

E-mail: [email protected]. Website: www.aocd.org/skin/dermatologic_diseases/ index.html. Summary: This fact sheet provides the parents of children or others who have hemangiomas with information on the treatment of these strawberry colored birthmarks. They vary from tiny blebs to large and multiple tumor like growths. Hemangiomas appear from birth up to 18 months. Most doctors agree that small hemangiomas should not be treated because many of them resolve on their own.

Hemangiomas that require early aggressive treatment include those that are causing psychosocial impairment; growing rapidly; or obstructing vision, hearing, breathing, eating, or any other body function. Most hemangiomas are superficial when first diagnosed, and they can be treated with a laser at this time. Repeated treatments can almost completely remove the superficial part of a hemangioma, but deeper portions will still exist. Deep hemangiomas have no red part on the skin but have large, soft, blood filled cavities with a blue hue. Compound hemangiomas, which have both superficial and deep parts, can be treated with steroid injections with or without liquid nitrogen cryosurgery. Oral steroids are needed to treat larger hemangiomas. Alfa interferon is recommended for hemangiomas that are nonresponsive to steroids or if the lesion is problematic or life threatening. Plastic surgery is needed for hemangiomas that are life threatening or deforming and have not responded to other treatment methods. 2 figures. •

PRICE: Single copy free to families of or persons with craniofacial anomalies; all others, minimum order of 20 booklets at $0.75 per booklet. Summary: This guide to hemangiomas is designed to answer frequently asked questions by parents. A hemangioma is a non-malignant tumor that is made up of rapidly growing endothelial or vascular cells. Written in a question-and-answer format, the guide covers the diagnosis and natural history of hemangiomas; the types of hemangiomas; the differences between hemangiomas and vascular malformations; etiologic factors; related problems; treatment options, including watchful waiting, corticosteroid therapy, chemical therapy, and surgery; and determining when to institute treatment for a particular child.

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 hemangioma. 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
