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 mitral valve prolapse 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 mitral valve prolapse, 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 mitral valve prolapse, 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 mitral valve prolapse. 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 mitral valve prolapse, 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 mitral valve prolapse. The Editors

CHAPTER 1. STUDIES ON MITRAL VALVE PROLAPSE Overview In this chapter, we will show you how to locate peer-reviewed references and studies on mitral valve prolapse.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and mitral valve prolapse, 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 “mitral valve prolapse” (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: •
Reliability of Self-Reported Heart Murmur History: Possible Impact on Antibiotic Use in Dentistry Source: JADA. Journal of the American Dental Association. 129(7): 861-866. July 1998. Summary: Administration of prophylactic antibiotics to a dental patient with a history of heart murmurs, rheumatic fever or mitral valve prolapse should be based on a reliable diagnosis of heart valve disease. This article reports on a study in which the authors investigated 68 patients with diabetes who reported having these heart valve conditions. The results showed that at least 65 percent of these patients actually had no evidence of a pathological heart murmur during two previous physical examinations. One subject was unaware that he had a pathological heart murmur as a result of mitral valve prolapse. These findings raise additional concerns regarding appropriate

premedication decisions, despite ongoing efforts by the American Heart Association to simplify and standardize the recommendations and indications for their application. The authors conclude that a self-reported history of heart valve disease should not be the sole criterion for antibiotic premedication. However, in an era of managed health care that emphasizes controlling costs, it is becoming more difficult to obtain appropriate evaluations that could confirm or rule out pathological heart valve defects. As a result, dentists may have to continue to empirically prescribe prophylactic antibiotic regimens for many of their patients who may not be at risk of developing endocarditis. This may have negative repercussions relative to the efficacy and future use of antibiotics. 1 figure. 1 table. 24 references. (AA-M). •
Dental and Cardiac Risk Factors for Infective Endocarditis: A Population-Based, Case-Control Study Source: Annals of Internal Medicine. 129(10): 761-769. November 15, 1998.

Summary: Although antibiotic prophylaxis against infective endocarditis is recommended, the true risk factors for infective endocarditis are unclear. This article reports on a study undertaken to measure the risk for endocarditis from dental treatment and cardiac abnormalities. In the case control study involving 54 hospitals in the Philadelphia area, persons with community acquired infective endocarditis not associated with intravenous drug use were compared with community residents, matched by age, sex, and neighborhood of residence. Information on demographic characteristics, host risk factors, and dental treatment was obtained from structured telephone interviews, dental records, and medical records. During the preceding 3 months, dental treatment was no more frequent among case patients than among controls. Of 273 case patients, 104 (38 percent) knew of previous cardiac lesions compared with 17 controls (6 percent). Case patients more often had a history of mitral valve prolapse, congenital heart disease, cardiac valvular surgery, rheumatic fever, and heart murmur without other known cardiac abnormalities. Among case patients with known cardiac lesions (the target of prophylaxis), dental therapy was significantly less common than among controls. Few participants received prophylactic antibiotics. The authors conclude that dental treatment does not seem to be a risk factor for infective endocarditis, even in patients with valvular abnormalities, but cardiac valvular abnormalities are strong risk factors. Few cases of infective endocarditis would be preventable with antibiotic prophylaxis, even with 100 percent effectiveness assumed. The authors note that current policies for prophylaxis should be reconsidered. 1 figure. 4 tables. 29 references. (AA-M).

A Drink to Your Health Source: Health. p.89-92. June 2000. Summary: This article discusses the many health benefits of drinking water. According to Dr. Ferydoon Batmanghelidj, author of "Your Body's Many Cries for Water", chronic dehydration may contribute to heartburn, headache, joint and pack pain, and fatigue. Susan M. Kleiner, assistant professor with the Nutritional Sciences Program at the University of Washington, has also researched the effects of chronic mild dehydration. According to her research, minor water shortage in the body can cause major health problems such as colon, bladder, or breast cancer, overweight, fatigue, and headaches. Other researchers have examined the effects of water on weight control. Researchers

suggest that drinking water regularly can help to reduce feelings of hunger. Barbara Rolls, professor of Nutrition at Pennsylvania State University, suggests "cooking" water into your diet through eating foods like hot cereal and soup. Water is also helpful in weight-control because it quenches thirst without adding unnecessary calories. Water may also help to alleviate fatigue, particularly for individuals suffering from mitral valve prolapse syndrome. Studies show that headaches are one of the most common side effects of dehydration, so drinking water regularly may help to prevent headaches. To obtain these health benefits and prevent dehydration, experts recommend drinking eight 8 oz. glasses of water every day. •
Prevention of Bacterial Endocarditis: Recommendations By the American Heart Association Source: JADA. Journal of American Dental Association. 128(7): 1142-1151. August 1997. Summary: This article excerpts the American Heart Association's recommendations on the prevention of bacterial endocarditis. These June 1997 recommendations were published to update 1990 guidelines for the prevention of bacterial endocarditis in individuals at risk for this disease. A major change in the update recommendations includes emphasizing that most cases of endocarditis are not attributable to an invasive procedure. The guidelines also stratifies cardiac conditions into high, moderate, and negligible risk categories based on potential outcome if endocarditis develops. Procedures that may cause bacteremia and for which prophylaxis is recommended are more clearly specified. An algorithm was developed to more clearly define when prophylaxis is recommended for patients with mitral valve prolapse. For oral or dental procedures, the initial amoxicillin dose is reduced to 2 g, a follow up antibiotic dose is no longer recommended, and erythromycin is no longer recommended for penicillinallergic individuals, but clindamycin and other alternatives are offered. The authors stress that these guidelines are meant to aid practitioners, but are not intended as the standard of care or as a substitute for clinical judgement. 1 figure. 3 tables. 42 references.

Dental Management of the Adolescent with Panic Disorder Source: Journal of Dentistry for Children. 60(6): 365-371. November-December 1993. Summary: This article explores the dental management of adolescents with panic disorder (PD), a psychiatric disease characterized by recurrent surges of severe anxiety without obvious cause. Panic disorder has special relevance for dentistry because it is often associated with mitral valve prolapse, a condition that may require endocarditis prophylaxis. In addition, the medications most often used to treat PD are associated with detrimental changes in the oral cavity and adverse interactions with dental therapeutic changes. Topics include characteristics of panic disorder, associated medical problems, epidemiology, etiology, the medical management of PD, and the dental management of children with PD, including anesthesia precautions. 60 references.

another problem or condition as opposed to a medical problem in and of itself. The author presents the primary causes of fatigue in three categories: lifestyle factors, medical conditions, and mood disorders. Lifestyle factors may include stress, nutrition, dehydration, exercise, and smoking. Among the medical conditions that may cause fatigue are high blood glucose, infection, hypothyroidism, heart disease, mitral valve prolapse, cancer, iron-deficiency anemia, iron overload, sleep disorders, and chronic fatigue syndrome. The author refers to depression and seasonal affective disorder as mood disorders which may cause fatigue. A health care professional should be consulted when fatigue is sudden or severe; is accompanied by symptoms such as fever, shortness of breath, or chest pain; or lasts more than two weeks without obvious cause. A sidebar provides nine tips for sleeping more peacefully. The article lists three organizations as sources of further information about fatigue. (AA-M). •
Improved Chest Expansion in Idiopathic Scoliosis After Intensive, MultipleModality, Nonsurgical Treatment in an Adult Source: Chest. 120(2): 672-674. August 2001. Summary: This journal article provides health professionals with information on the case of a middle aged woman who had stable right thoracic spinal curvature due to idiopathic scoliosis and was treated with traction to improve pulmonary function. The woman had a prominent rib hump, scapular and torso asymmetry, thoracic lordosis, and forward rotation of the right shoulder which were detected at age 11 years. Radiographic analysis revealed a right thoracic curvature of 43 degrees with lesser curvatures in the cervical and lumbar spine. In addition, pectus excavatum and mitral valve prolapse also were present. Daily torso strengthening and conditioning exercises were carried out through February 1992. From 1993 to 2000, the woman underwent intensive psychological and mobilization therapies, including comprehensive manipulative medicine treatments and daily manual traction. During this period, a 6 centimeter increase in resting chest circumference (in the absence of weight gain) and a 7.5 centimeter increase in chest expansion were correlated with a substantial reduction of incidence of respiratory infections. Mechanisms of chest wall expansion probably include altered muscle tonus through neuroreflexive mechanisms and plastic tissue changes from directed applied forces and, over time, self-stretching through deeper breathing. 2 figures and 6 references.

Water: An Essential But Overlooked Nutrient Source: Journal of the American Dietetic Association. 99(2): 200-206. February 1999. Summary: This review article addresses the current knowledge of the effects of chronic mild dehydration on human performance and health; in it, the author calls for a revival of patient or client education regarding water intake. To be well hydrated, the average sedentary adult man must consume at least 2,900 mL (11 c) of fluid per day, and the average sedentary adult woman at least 2,200 mL (9 c) of fluid per day, in the form of noncaffeinated, nonalcoholic beverages, soups, and foods. Solid foods contribute approximately 1,000 mL (4 c) of water, with an additional 250 mL (1 c) coming from the water of oxidation. The Nationwide Food Consumption Surveys indicate that a portion of the population may be chronically mildly dehydrated. Several factors may increase the likelihood of chronic, mild dehydration, including a poor thirst mechanism, dissatisfaction with the taste of water, common consumption of the natural diuretics caffeine and alcohol, participation in exercise, and environmental conditions. Dehydration of as little as 2 percent loss of body weight results in impaired physiological and performance responses. New research indicates that fluid

consumption in general and water consumption in particular can have an effect on the risk of urinary stone disease; cancers of the breast, colon, and urinary tract; childhood and adolescent obesity; mitral valve prolapse; salivary gland function; and overall health in the elderly. The author concludes that dietitians should be encouraged to promote and monitor fluid and water intake among all their clients and patients through education and to help them design a fluid intake plan. The influence of chronic mild dehydration on health and disease merits further research. 4 figures. 81 references. (AA).
Federally Funded Research on Mitral Valve Prolapse The U.S. Government supports a variety of research studies relating to mitral valve prolapse. 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 mitral valve prolapse. 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 mitral valve prolapse. The following is typical of the type of information found when searching the CRISP database for mitral valve prolapse: •

Cardiovascular abnormalities associated with the connective tissue disorders Marfan syndrome and congenital contractural arachnodactyly have been linked genetically and biochemically to the microfibrillar ECM proteins fibrillin 1 and 2 respectively. In addition to ocular and skeletal abnormalities, patients with these disorders manifest aortic root dilatation, aortic insufficiency, and mitral valve prolapse. A neonatal form of Marfan syndrome causes severe cardiovascular defects and leads to death within the first year. Epifluorescence microscopy indicates fibrillin-1 and -2 positive fibrils are present in the epicardium, dorsal mesocardium, and enclocardial cushion tissue/valve primordial of avian embryos, and surround the forming bilateral dorsal aortae; implicating the fibrillins in cardiovascular morphogenesis. These microfibrils may impart stability or provide extensible properties to these regions, which are subject to stress/strain. To address the function(s) of fibrillins during early cardiovascular development we will use 2

time-lapse imaging, fibrillin marker antibodies, and computational analyses to document fibrillin assembly/reorganization and motion in the avian embryo bilateral heart forming tissues, endocardial cushions/valve primordia, and major embryonic vessels in normal embryos. Further, we propose to monitor the effects of experimentally perturbing microfibril assembly on cardiovascular development. Similarly, we will monitor the effects of altering cardiovascular (CV) morphogenesis (at the tissue level) on fibrillin assembly. Finally, we will use a complementary mouse explant culture system to monitor dynamically fibrillin assembly in normal and transgenic CV tissue, We hypothesize that dynamic microfibril assembly is key for normal cardiac development, and that disruption of orderly assembly leads to cardiovascular malformations. Examining fibrillin fibril assembly will lead to a better understanding of connective tissue-related cardiovascular defects. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: ECHOCARDIOGRAPHIC STROKE PREDICTORS IN A TRI-ETHNIC COMM Principal Investigator & Institution: Di Tullio, Marco R.; Medicine; Columbia University Health Sciences New York, Ny 10032 Timing: Fiscal Year 2001; Project Start 30-SEP-2000; Project End 31-AUG-2004 Summary: (Adapted From The Applicant's Abstract): The candidate's previous activity has been devoted to patient-oriented research. In recent years, he has focused on the use of echocardiography to identify new cardioembolic sources for ischemic stroke, especially patent foramen ovale and aortic arch plaques, and has`been awarded two R01 grants from NINDS for such efforts. The candidate's overall career goal is to continue his research in the field of cardioembolic stroke, contributing to the explanation of the mechanisms of some cryptogenic strokes and therefore to a rational preventive and therapeutic approach. The candidate is also committed to mentoring young investigators, as documented by his long-standing and successful training of cardiology, fellows. Columbia University is an ideal environment to foster the candidate's career growth because of the strong, infrastructure for clinical research, the presence of world renowned cardiologists and neurologists for consultation and collaboration, and the firm institutional commitment to patient-oriented research. Crucial to the candidate's career development will be the transition from the relatively small case-control studies performed so far to the proposed large prospective study of subclinical echocardiocraphic abnormalities and stroke risk. A population-based prospective cohort study is proposed to determine the independent contribution of left ventricular hypertrophy (LVH) and geometric pattern, decreased LV ejection fraction, segmental wall motion abnormalities and left atrial enlargement to the risk of ischemic stroke and vascular events in a tri-ethnic population, and the existence of a dose-response relationship. The progression of these abnormalities over time will also be assessed. Secondary aims will be to evaluate the modification of risk by traditional stroke risk factors, and the assessment of the risk associated with less frequent abnormalities (patent foramen ovale, mitral annular calcification, mitral valve prolapse). Finally, the prevalence of a patent foramen ovale in each race-ethnic group will be evaluated. A cohort of 2500 white, black and Hispanic adults over age 55 will be enrolled from the ongoing Northern Manhattan Stroke Study (NOMASS), assuring cost-effective recruitment, data collection and follow-up. Two-dimensional echocardiography with contrast injection will be performed. A new three-dimensional technique will also be used to assess LVH. Annual telephone follow-up will be performed to ascertain stroke, myocardial infarction and death. In-person follow-up will be done in subjects with

suspected outcome and in a random 10% of the cohort. Kaplan Meier curves and Coxproportional hazard models will be used to calculate adjusted event rates and assess the dependence of exposures of interest on stroke and vascular events adjusting for demographics and stroke risk factors. In a subgroup of 900 subjects, echocardiography will be repeated 3 years after the first test to study the progession of echocardioaraphic abnormalities. This study will be the first prospective cohort study to evaluate the role of multiple echocardiographic risk factors for ischemic stroke in a community of whites, blacks and Hispanics living in the same area.

Project Title: MVPS: HEALTH CONCERNS, ROLE FUNCTION, HEALTH SERVICE USE Principal Investigator & Institution: Scordo, Kristine A.; None; Wright State University Colonel Glenn Hwy Dayton, Oh 45435 Timing: Fiscal Year 2002; Project Start 15-MAR-2002; Project End 14-MAR-2004 Summary: (provided by applicant) Mitral valve prolapse (MVP) is the most common valvular heart disease with millions of people newly diagnosed each year. Some of these patients have actual structural changes that require mitral valve replacement; others have a constellation of symptoms that are unrelated to these structural changes and are diagnosed with MVP syndrome (MVPS). For these individuals, treatment is aimed at symptom control. While the course for those with anatomical valvular dysfunction is documented, the course for those with MVPS is less well known. Anecdotal reports by individuals with MVPS indicate a variety of frightening symptoms, including chest pain, shortness of breath, palpitations, migraine headaches, lightheadedness, fatigue, dizziness on standing, mood swings, and anxiety or panic attacks. Individuals with these symptoms often seek help in emergency rooms; urgent care centers, and primary care offices. However, little is known about the profile and the effects of these symptoms on the individual's role status, and use of health care services. Thus, the purpose of this study is to develop a profile of health concerns, symptoms and treatments, and to examine the relationships of symptoms to functional and role status and use of health care services for patients diagnosed with MVPS. Specifically, the research questions are: (1) what are the health concerns, symptoms, and treatments reported by patients with MVPS? (2) Are symptoms related to age, time since diagnosis, symptoms, anxiety, social support, diet (magnesium, sodium, water and caffeine), and treatment (beta and calcium channel blockers; anxiolytics; mediation/relaxation therapy; fluid; exercise; activity limitation)? (3) What is the relationship of symptoms to patients' health concerns, functional and role status, and use of health care services? A descriptive cross-sectional design will be used. Questionnaire packets will be mailed to all of the men and women (N = 3022) on The Mitral Valve Prolapse Program of Cincinnati's mailing list diagnosed with MVPS. The self-complete questionnaires will include measures of MVPS symptoms (MVPS symptom checklist); the outcome variables of health concerns (MUIS), functional and role status (SF-36), and healthcare service use (Life History Calendar); and the independent variables of age, time since diagnosis, anxiety (STAI), social support (MOS Social Support), treatment, and diet (Food Frequency Questionnaire). Descriptive statistics and multiple regression analysis will be used to address the study's research questions. The proposed study is the next step in developing data on symptoms of MVPS and their effect on health and functioning. These data are necessary in developing and modifying existing education and self management interventions aimed at reducing anxiety and improving the health and well being of the millions of Americans newly diagnosed with this syndrome annually.

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

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

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

CHAPTER 2. NUTRITION AND MITRAL VALVE PROLAPSE Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and mitral valve prolapse.
Finding Nutrition Studies on Mitral Valve Prolapse 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 “mitral valve prolapse” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

In addition to LOCATORPlus, in collaboration with authors and publishers, the National Center for Biotechnology Information (NCBI) is currently adapting biomedical books for the Web. The books may be accessed in two ways: (1) by searching directly using any search term or phrase (in the same way as the bibliographic database PubMed), or (2) by following the links to PubMed abstracts. Each PubMed abstract has a "Books" button that displays a facsimile of the abstract in which some phrases are hypertext links. These phrases are also found in the books available at NCBI. Click on hyperlinked results in the list of books in which the phrase is found. Currently, the majority of the links are between the books and PubMed. In the future, more links will be created between the books and other types of information, such as gene and protein sequences and macromolecular structures.

Marfan Syndrome, The Source: in Coggins, C.H.; Hancock, E.W.; Levitt, L.J., eds. Annual Review of Medicine, Volume 51, 2000. Palo Alto, CA: Annual Reviews, Inc. 2000. p. 481-510.

[email protected]. Website: www.AnnualReviews.org. Summary: This chapter provides health professionals with information on the historical evolution, classification, clinical features, diagnosis, and pathogenesis of Marfan syndrome (MFS). This heritable disorder of connective tissue was initially described just over 100 years ago and was among the first conditions classified as a heritable disorder of connective tissue. MFS lies at one end of a phenotypic continuum, with people in the general population who have one or another of the features of MFS at the other end, and those with a variety of other conditions in between. Diagnosis of MFS and these other conditions is based on clinical features. Mutations in FBN1, the gene that encodes fibrillin-1, are responsible for MFS and, in a few patients, other disorders in the continuum. Differential diagnosis of MFS is hampered by the range of FBN1 mutations in MFS and related conditions, the considerable prevalence of many phenotypic manifestations in the general population and in other connective tissue disorders, and the existence of phenotypic continua. In addition to skeletal, ocular, and cardiovascular features, patients with MFS have involvement of the skin, integument, lungs, and muscle tissue. Related disorders include MASS phenotype, familial mitral valve prolapse, familial aortic aneurysm and dissection, familial ectopia lentis, familial tall stature, contractural arachnodactyly, and Shprintzen-Goldberg syndrome. Over the past 30 years, evolution of aggressive medical and surgical management of the cardiovascular problems, especially mitral valve prolapse, aortic dilatation, and aortic dissection, has resulted in considerable improvement in life expectancy. 5 tables and 131 references.

Oral features associated with Turner's syndrome include high arched and narrow palate, occurrence of cleft palate at higher-than-normal frequency, significantly smaller mesio-distal dimensions of the teeth, bifurcated roots and reduced root length, particularly in the maxilla (upper jaw), premature tooth eruption, increased molarization of premolars, and the presence of hypoplasia. The article then describes a case of the management of a patient diagnosed with Turner's syndrome. The young woman (age 21 years) presented with severe retrognathia, posterior open bite, crossbite on the right side, generalized enamel hypoplasia, shortened roots, thin dentin, compromised dexterity, osteoporosis, mitral valve prolapse, and low self-esteem. The dentist and dental hygienist provided this patient with comprehensive care in consultation with the patient's physician and other dental specialists. A posttest with which readers can obtain continuing education credit is appended to the article. 5 figures. 2 tables. 29 references.

CHAPTER 8. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for mitral valve prolapse. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a non-profit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with mitral valve prolapse. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.).

It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/. PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee.

Coffee Break: Tutorials for Biologists17 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.18 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.19 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/.
17 Adapted 18
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. 19 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.
87
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 mitral valve prolapse 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 mitral valve prolapse. 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 mitral valve prolapse. 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 “mitral valve prolapse”:

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 mitral valve prolapse. 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.

Connective tissue is the glue and scaffolding of the body, and is also important in development before birth, growth after birth, cushioning of joints, and enabling passage of light through the eye. All organs contain connective tissues and the manifestations of the Marfan syndrome appear in many parts of the body. Early diagnosis and management of the Marfan syndrome can save lives. This brochure familiarizes pediatricians with the manifestations of the disorder so that children suspected of having Marfan syndrome can be evaluated in a timely fashion and enrolled in an appropriate treatment plant. Topics include a definition, the causes of Marfan (genetic), the challenges of diagnosing Marfan syndrome in children, diagnostic criteria for Marfan syndrome, related diagnoses (emerging Marfan syndrome, isolated skeletal features, mitral valve prolapse syndrome, MASS phenotype, familial ectopia lentis, familial aortic aneurysm), the principles of follow up and effective management, and the other special needs of children diagnosed with Marfan syndrome, including school issues, physical activity, and social issues. The brochure concludes with a description of the National Marfan Foundation, a nonprofit voluntary health organization dedicated to saving lives and improving the quality of life for people and families affected by the Marfan syndrome and related disorders.

dermatological, ophthalmological, cardiovascular, and gastrointestinal systems. Although the prevalence of PXE is believed to be about 1 in 50,000, it is probably more common because many patients are undiagnosed. Equal numbers of men and women are affected, and the disease is often diagnosed between the ages of 30 and 50. Skin manifestations are usually the most prominent and visible symptoms, and many patients report having had unrecognized symptoms for 10 years or more. Primary PXE lesions are 1-5 millimeter yellow-orange papules of varying shapes. Lesions may form groups and usually progress downward from the neck. Although skin manifestations are the most prominent feature, the ophthalmologic, cardiovascular, and gastrointestinal manifestations are medically more significant. Ocular changes usually occur in adults and include angioid streaks, retinal hemorrhage, and loss of central vision. Cardiovascular problems include coronary artery disease, peripheral artery disease with intermittent claudication, easy fatigability, mitral valve prolapse, and hypertension. Gastrointestinal bleeding is sometimes seen in younger children. The fact sheet also discusses genetic aspects and offers suggestions on caring for patients with PXE and preventing complications. •

[email protected]. Website: www.pxe.org. PRICE: Single copy free. Summary: This fact sheet for parents of a child with pseudoxanthoma elasticum (PXE) presents an overview of this rare, heterogeneous, inherited disorder that causes calcification of the connective tissue. The skin, retina, and cardiovascular and gastrointestinal systems are most commonly affected. Skin manifestations are usually the most prominent and visible. Primary PXE lesions are 1-5 millimeter yellow-orange papules of varying shapes. Lesions may form groups and usually progress downward from the neck. Although skin manifestations are its most prominent feature, ophthalmologic, cardiovascular, and gastrointestinal manifestations are medically more significant. Ocular changes usually occur in adults and include peau d'orange, angioid streaks, retinal hemorrhage, and loss of central vision. Cardiovascular problems, which are usually not present in children, either include coronary artery disease, peripheral artery disease with intermittent claudication, easy fatigability, mitral valve prolapse, and hypertension. Gastrointestinal bleeding is sometimes seen in younger children, however. The fact sheet also discusses the genetic aspects of PXE, offers suggestions for caring for a child with the disease, and addresses the emotional issues raised when a child is diagnosed. The NIH Search Utility
The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to mitral valve prolapse. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html.

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.20
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

MITRAL VALVE PROLAPSE DICTIONARY The definitions below are derived from official public sources, including the National Institutes of Health [NIH] and the European Union [EU]. Abdominal: Having to do with the abdomen, which is the part of the body between the chest and the hips that contains the pancreas, stomach, intestines, liver, gallbladder, and other organs. [NIH] Ablation: The removal of an organ by surgery. [NIH] Abscess: Accumulation of purulent material in tissues, organs, or circumscribed spaces, usually associated with signs of infection. [NIH] Acceptor: A substance which, while normally not oxidized by oxygen or reduced by hydrogen, can be oxidized or reduced in presence of a substance which is itself undergoing oxidation or reduction. [NIH] Adenine: A purine base and a fundamental unit of adenine nucleotides. [NIH] Adenosine: A nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter. [NIH] Adrenal Cortex: The outer layer of the adrenal gland. It secretes mineralocorticoids, androgens, and glucocorticoids. [NIH] Adrenal Medulla: The inner part of the adrenal gland; it synthesizes, stores and releases catecholamines. [NIH] Adrenergic: Activated by, characteristic of, or secreting epinephrine or substances with similar activity; the term is applied to those nerve fibres that liberate norepinephrine at a synapse when a nerve impulse passes, i.e., the sympathetic fibres. [EU] Adverse Effect: An unwanted side effect of treatment. [NIH] Aerobic: In biochemistry, reactions that need oxygen to happen or happen when oxygen is present. [NIH] Affinity: 1. Inherent likeness or relationship. 2. A special attraction for a specific element, organ, or structure. 3. Chemical affinity; the force that binds atoms in molecules; the tendency of substances to combine by chemical reaction. 4. The strength of noncovalent chemical binding between two substances as measured by the dissociation constant of the complex. 5. In immunology, a thermodynamic expression of the strength of interaction between a single antigen-binding site and a single antigenic determinant (and thus of the stereochemical compatibility between them), most accurately applied to interactions among simple, uniform antigenic determinants such as haptens. Expressed as the association constant (K litres mole -1), which, owing to the heterogeneity of affinities in a population of antibody molecules of a given specificity, actually represents an average value (mean intrinsic association constant). 6. The reciprocal of the dissociation constant. [EU] Agonist: In anatomy, a prime mover. In pharmacology, a drug that has affinity for and stimulates physiologic activity at cell receptors normally stimulated by naturally occurring substances. [EU] Albumin: 1. Any protein that is soluble in water and moderately concentrated salt solutions and is coagulable by heat. 2. Serum albumin; the major plasma protein (approximately 60 per cent of the total), which is responsible for much of the plasma colloidal osmotic pressure
108 Mitral Valve Prolapse
and serves as a transport protein carrying large organic anions, such as fatty acids, bilirubin, and many drugs, and also carrying certain hormones, such as cortisol and thyroxine, when their specific binding globulins are saturated. Albumin is synthesized in the liver. Low serum levels occur in protein malnutrition, active inflammation and serious hepatic and renal disease. [EU] Aldosterone: (11 beta)-11,21-Dihydroxy-3,20-dioxopregn-4-en-18-al. A hormone secreted by the adrenal cortex that functions in the regulation of electrolyte and water balance by increasing the renal retention of sodium and the excretion of potassium. [NIH] Alertness: A state of readiness to detect and respond to certain specified small changes occurring at random intervals in the environment. [NIH] Algorithms: A procedure consisting of a sequence of algebraic formulas and/or logical steps to calculate or determine a given task. [NIH] Alkaline: Having the reactions of an alkali. [EU] Alkalosis: A pathological condition that removes acid or adds base to the body fluids. [NIH] Alprenolol: 1-((1-Methylethyl)amino)-3-(2-(2-propenyl)phenoxy)-2-propanol. Adrenergic beta-blocker used as an antihypertensive, anti-anginal, and anti-arrhythmic agent. [NIH] Alternative medicine: Practices not generally recognized by the medical community as standard or conventional medical approaches and used instead of standard treatments. Alternative medicine includes the taking of dietary supplements, megadose vitamins, and herbal preparations; the drinking of special teas; and practices such as massage therapy, magnet therapy, spiritual healing, and meditation. [NIH] Amino Acid Sequence: The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining protein conformation. [NIH] Amino Acids: Organic compounds that generally contain an amino (-NH2) and a carboxyl (COOH) group. Twenty alpha-amino acids are the subunits which are polymerized to form proteins. [NIH] Amino Acids: Organic compounds that generally contain an amino (-NH2) and a carboxyl (COOH) group. Twenty alpha-amino acids are the subunits which are polymerized to form proteins. [NIH] Amoxicillin: A broad-spectrum semisynthetic antibiotic similar to ampicillin except that its resistance to gastric acid permits higher serum levels with oral administration. [NIH] Ampicillin: Semi-synthetic derivative of penicillin that functions as an orally active broadspectrum antibiotic. [NIH] Anaesthesia: Loss of feeling or sensation. Although the term is used for loss of tactile sensibility, or of any of the other senses, it is applied especially to loss of the sensation of pain, as it is induced to permit performance of surgery or other painful procedures. [EU] Analog: In chemistry, a substance that is similar, but not identical, to another. [NIH] Anatomical: Pertaining to anatomy, or to the structure of the organism. [EU] Anemia: A reduction in the number of circulating erythrocytes or in the quantity of hemoglobin. [NIH] Anesthesia: A state characterized by loss of feeling or sensation. This depression of nerve function is usually the result of pharmacologic action and is induced to allow performance of surgery or other painful procedures. [NIH] Aneurysm: A sac formed by the dilatation of the wall of an artery, a vein, or the heart. [NIH] Angina: Chest pain that originates in the heart. [NIH]
Dictionary 109
Angina Pectoris: The symptom of paroxysmal pain consequent to myocardial ischemia usually of distinctive character, location and radiation, and provoked by a transient stressful situation during which the oxygen requirements of the myocardium exceed the capacity of the coronary circulation to supply it. [NIH] Angioid Streaks: Small breaks in the elastin-filled tissue of the retina. [NIH] Angiotensinogen: An alpha-globulin of which a fragment of 14 amino acids is converted by renin to angiotensin I, the inactive precursor of angiotensin II. It is a member of the serpin superfamily. [NIH] Angulation: Deviation from the normal long axis, as in a fractured bone healed out of line. [NIH]
Antagonism: Interference with, or inhibition of, the growth of a living organism by another living organism, due either to creation of unfavorable conditions (e. g. exhaustion of food supplies) or to production of a specific antibiotic substance (e. g. penicillin). [NIH] Anti-Anxiety Agents: Agents that alleviate anxiety, tension, and neurotic symptoms, promote sedation, and have a calming effect without affecting clarity of consciousness or neurologic conditions. Some are also effective as anticonvulsants, muscle relaxants, or anesthesia adjuvants. Adrenergic beta-antagonists are commonly used in the symptomatic treatment of anxiety but are not included here. [NIH] Antibacterial: A substance that destroys bacteria or suppresses their growth or reproduction. [EU] Antibiotic: A drug used to treat infections caused by bacteria and other microorganisms. [NIH]
Antibiotic Prophylaxis: Use of antibiotics before, during, or after a diagnostic, therapeutic, or surgical procedure to prevent infectious complications. [NIH] Antibodies: Immunoglobulin molecules having a specific amino acid sequence by virtue of which they interact only with the antigen that induced their synthesis in cells of the lymphoid series (especially plasma cells), or with an antigen closely related to it. [NIH] Antibody: A type of protein made by certain white blood cells in response to a foreign substance (antigen). Each antibody can bind to only a specific antigen. The purpose of this binding is to help destroy the antigen. Antibodies can work in several ways, depending on the nature of the antigen. Some antibodies destroy antigens directly. Others make it easier for white blood cells to destroy the antigen.

[EU] Complement: A term originally used to refer to the heat-labile factor in serum that causes immune cytolysis, the lysis of antibody-coated cells, and now referring to the entire functionally related system comprising at least 20 distinct serum proteins that is the effector not only of immune cytolysis but also of other biologic functions. Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
