A fine team of state-of-the-art researcher/clinicians who know their fields, have contributed to the advancement of knowledge, and are in a position to judge what is truly important have here pooled their thoughts in a series of chapters on the cutting edges of gastroenterology. Four attributes render this volume superior to other update-oriented publications. The first striking feature, which is immediately evident upon scanning the table of contents, is the imaginative choice of subjects, ranging from trav eler's diarrhea and sexually transmitted GI infections through TPN and interventional endoscopy to geriatrics and iatrogenic disease. A second outstanding feature of this volume is its success in balanc ing basic pathophysiology with practical considerations of clinical man agement. This is achieved in the discussions of such diverse topics as acid-peptic diseases, infectious and other diarrheal syndromes, and hep atitis immunization. Throughout the book we are led smoothly from basic science principles to specific recommendations for diagnosis and therapy. This practical emphasis appears repeatedly and sometimes pro duces a delightful surprise, such as a chapter on radiology that is not tech nology-based but instead problem-oriented."

My conviction is that the matters addressed in this volume are of transcendental importance if we are to face up to the challenges of the 1990s and beyond. How, for instance, are we to cope with a truly ecological approach to public health and all its concomitant changes of risk groups worldwide unless there is a full appre ciation of the popUlation perspective throughout the health establishment? The global village has achieved a measure of interdependence requiring recognition by all concerned with the health of both individuals and communities that there is an urgent need to share our knowledge and deploy our resources in the best interests of people everywhere. The history of public health initiatives, the origins of epidemiology, and the tragic separation-virtually a divorce--of public health from medicine recounted in the chapters that follow argue strongly for an early rapprochement. Health professionals who complement each other's knowledge and skills can be reunited through their common reliance on epidemiology as a major fundamental science for the entire health enterprise. Henceforth, epidemiology should be ranked in importance with cellular and molecular biology, immunology, and the social and systems sciences; all are essential if we are to cope with the vast array of diseases and disorders that face us in both the developed and developing worlds. We need more first-rate laboratory scientists, clinicians, nurses, aides, village health work ers, and managers committed to serving the public."

More than half a million people worldwide are now sustained by renal replacement therapy, mainly hemodialysis at a cost exceeding USD 30 billion per year. Each case of ESRD that is delayed or prevented saves funds that may be applied to other aspects of health care. Edited by an internationally renowned nephrologist, Prognosis for Kidney Disorders provides a timely summary of exciting work in progress directed toward renoprotection and of ultimate interdiction of ESRD.
Suitable for researchers and clinicians, Dr. Morrell Michael Avram has collected and commented on promising initiatives likely to enter everyday practice in the immediate future. Suitable for renal trainees, experienced kidney doctors, nurses, nutritionists and cardiologists.

Non-Parametric Statistical Diagnosis

Physicians in most developed countries are at a great disadvantage when confronted with geographic and tropical diseases. They may be faced with prevention for patients who are outward bound or with diagnosis and treatment on their return. The practitioners' difficulties relate to inade quate teaching in medical schools and to the infrequency with which they are confronted with these exotic diseases. It is quite surprising to realize the extent of travel by Americans to areas where the tropical diseases abound: in 1979 there were 3 million trips by U. S. residents to Central and South America and almost 1 million to Africa and Asia. I Further, the influx from the tropics to the United States in 1978 involved 4. 5 million visitors and more than half a million immigrants. I The single most danger ous ofthese infections is malaria, which is now averaging about 500 cases yearly in the United States; it is important to realize that infection with one species of this organism (Plasmodium falciparum) can be lethal within a few days of the onset of fever. Highly contagious infections such as the newly discovered and extremely lethal Lassa and Ebola fevers may be imported to our shores, plus cholera, antibiotic-resistant bacillary dys entery, and amebic dysentery and liver abscess. Chronic worm infections such as schistosomiasis, although rarely lethal, may have severe conse 2 quences such as paraplegia or hematemesis."

During September 10-14, 1984, we held a Research Workshop at the Lake Arrowhead Conference Center, California, bringing togeth er leaders in the field of electronic spatial sensors for the blind from the psychology, engineering, and rehabilitation areas. Our goal was to engage these groups in discussion with one another about prospects for the future of electronic spatial sensing, in the light of emerging technologies and the increasing sophistica tion of behavioral research related to this field. The papers in this book give an update on several of the key research traditions in thi s fi e 1 d. Broader overvi ews are provi ded in the paper by Brabyn, and in our Historical Overview, Final Commentary and the Introductions to each section. In a field as complex as this, some overlap of discussion is desirable and the reader with a serious interest in this field is advised to sample several opinions. This volume, and the conference on which it is based, received assistance from many people and organizations. The Scientific Affai rs Divi sion of the North Atl antic Treaty Organization sup ported the conference as part of their program of Advanced Research Workshops, and the Science and Technology to Aid the Handicapped Program of the National Science Foundation provided additional major financial support. The Center for Social and Behavioral Sciences Research of the University of California, Riverside provided financial as well as major logistical support."

Antibiotics will soon no longer be able to cure common illnesses such as strep throat, sinusitis and middle ear infections as they have done for the last 60 years. Antibiotic-resistant bacteria are increasing at a much faster rate than new antibiotics to treat them are being developed. The prescription of antibiotics for viral illnesses is a key cause of increasing bacterial resistance. Despite this fact, many children continue to receive antibiotics unnecessarily for the treatment of viral upper respiratory tract infections. Why do American physicians continue to prescribe inappropriately given the high social stakes of this action? The answer appears to lie in the fundamentally social nature of medical practice: physicians do not prescribe as the result of a clinical algorithm but prescribe in the context of a conversation with a parent and a child. Thus, physicians have a classic social dilemma which pits individual parents and children against a greater social good.
This book examines parent-physician conversations in detail, showing how parents put pressure on doctors in largely covert ways, for instance in specific communication practices for explaining why they have brought their child to the doctor or answering a history-taking question. This book also shows how physicians yield to this seemingly subtle pressure evidencing that apparently small differences in wording have important consequences for diagnosis and treatment recommendations. Following parents use of these interactional practices, physicians are more likely to make concessions, alter their diagnosis or alter their treatment recommendation. This book also shows how small changes in the way physicians present their findings and recommendations can decrease parent pressure for antibiotics. This book carefully documents the important and observable link between micro social interaction and macro public health domains.

Prevention of disease and injury, including early identification of risks and disease and optimal control of potentially debilitating or fatal complications of chronic conditions, is the area of clinical medicine that holds the greatest promise for improving human health. Each year a long list of major, but potentially preventable health problems exacts a terrible human and financial toll. These problems urgently need our attention, especially as major advances in curative medicine become more complex and costly. Prevention of disease and injury may well be the central health issue of our time, an issue of vital concern to every quarter of our society. Now is a very good time to promote prevention. Citizens and some social groups are increasingly aware of and interested in health and fitness issues. There is great enthusiasm about-even obsession with-health, and we are seeing an astonishing proliferation of health publications and media presentations for laymen, fitness and weight control cen ters, exercise programs, health food stores, disease support groups, health education programs, and do-it-yourself diagnostic kits. All of this betokens an increased health consciousness on the part of public and perhaps signals greater individual accountability for health."

This timely and important work looks at the collaborative health care model for the delivery of mental health care in a primary care setting. This has become the ideal model for the treatment of comorbid medical and psychiatric or psychological disorders. There is also an increased awareness that pharmacological intervention, the most frequently delivered intervention for psychological disorders, is often of limited effectiveness without concurrent specific psychological intervention. The book includes more than two dozen case studies, co-written by clinical psychologists and primary care physicians. It is essential reading for any psychology practitioner in a clinical setting, as well as for health care administrators.

The NATO Advanced Study Institute (ASI) on Physics and Engineering of Medical Imaging has addressed a subject which in the wide area of biomedical technology is one of those which are showing greater impact in the practice of medicine for the ability to picture both Anatomy and Physiology. The information and accuracy obtained by whatever imaging methodology is a complex result of a multidisciplinary effort of several sciences such as Physics, Engineering, Electronics, Chemistry, Medicine, etc ... Development has occurred through work performed in different environments such as basic and applied research laboratories, industries and clinical centers, with the aim of achieving an efficient transfer of know-how and technology for the improvement of both investigation possibilities and health care. On one hand, such an effort requires an ever-increasing committment of human and financial resources at research and industrial level, and, on the other, it meets serious difficulties in recruiting the necessary human expertise oriented to this technology which breaks with the tradi tiona I academic borders of the single disciplines. Furthermore, the scientific community is continually dealing with the problem of increasing the performance and, at the same time, complexity and costs of instruments, applying more and more sophisticated technology in an effort to meet the demand for more complete and accurate clinical information. The scientific program of this ASI and the qualification of the authors reveals the intrinsic complexity of the development process of the Imaging methodologies.

In the decade since AIDS was first recognised the enormous and worldwide social and medical implications of this disease have been increasingly recognised. The exponential increase in the number of people infected with HIV has been paralleled by the written literature on the subject. When this book was initially conceived the question was why another book? It seemed to me at that time and since, that as HIV presented ever more complex problems, they were best solved when considered within a wider context, using basic principles of individual medical specialties and applying them. For this reason, all the chapter authors were experienced in a particular field and applied that knowledge to HIV. All the authors were working at the Middlesex Hospital in London when the AIDS services there were expanding to fill a need, from 2 beds in 1986 to two wards today. The authors were frontline staff looking after all aspects of HIV infection within a wider general medical context. Many are now consultants or senior lecturers. It is the aim of the book to provide an insight into HIV and AIDS as a overview for someone starting to work in this field or who sees such patients occasionally and requires some basic guidelines. For this reason the chapters are based predominantly on organ systems and are divided into sections covering the presenta tion, methods of investigation and treatment or action required of relevant conditions."

This book has been designed, as its title implies, as a practical book for medical practitioners, although it should be of interest to medical students and nutritionists. It attempts to provide essential information about this important group of substances rather than be an all embracing monograph on the subject. For this reason biochemical and physiological considera tions have been kept to a minimum, and aspects of animal disorders and animal husbandry have not been considered. The material is often presented in a rather dogmatic fashion and, with rare exceptions, references are not included since this makes reading more difficult. The exceptions, where references are provided, are the therapeutic claims, and the series of recent studies which have indicated that vitamin deficiencies are still widely present among certain groups of the population of many industrially developed countries. To add to this reference list there is a reading list which has been selected to give key books, reviews with extensive bibliography and important articles over the past 10 years. From this reading list it is possible to trace most of the literature on the vitamins since they were first described over half a century ago."

Both thyroid dysfunction and heart failure show a high prevalence in the adult population. Frequently, in clinical practice, a multidisciplinary approach is useful to optimize the management of patients with these conditions. Although there is no doubt regarding the close link between cardiovascular pathophysiology and thyroid homeostasis, our understanding of this association is far from being exhaustive. Thyroid hormone regulates the expression of cardiac-specific functional contractile and structural proteins and plays a pivotal role in modulating both diastolic and systolic function as well as peripheral vascular resistance. The close relationship between thyroid and heart dysfunction is strongly supported by recent evidence demonstrating that an altered thyroid profile is a negative prognostic predictor in patients with heart failure. The treatment of chronic heart failure, especially in advanced stages of the disease, continues to be an open and challenging field. The potential of novel thyroid hormone therapies that address the molecular biology of thyroid dysfunction and heart failure thus represents an attractive area of multidisciplinary scientific interest. This book is a readable, integrated, and highly up to date presentation of the clinical, pathophysiological, and basic science aspects of thyroid-heart failure interactions. It addresses a complex subject in an approach that targets a large audience of readers.

There are many changes in the skin, hair, and nails during and after pregnancy. Patients are certainly aware that those changes are occurring, but few physicians and even fewer patients know how to predict the course of those changes. Pigmentary changes occur, but are they permanent? Can they be prevented or reversed? Hair may become thicker during pregnancy, only to fall out in the postpartum period. When will hair stop falling out? Will it grow back? What hormonal changes are occurring to produce these effects on the skin, hair, and nails? Will those hormonal changes affect other organs? Some cutaneous manifestations of pregnancy are common and recognized by most physicians. Abdominal striae, for example, are easily identified, but physicians have many questions about them. Why do they develop? Can they be prevented or treated? Other cutaneous manifestations of pregnancy are less common and recognized by few. For example, pruritic urticarial papules and plaques of pregnancy is a debilitating condition that is treatable once diagnosed. Even more important than the treatment, the knowledge imparted to a worried mother that her child will be fine and that the condition is se- limited is priceless; but the condition must first be recognized by the patient's physician. All of these questions and conditions are addressed in this extraordinary book. Pigm- tary disorders are addressed in detail in Chap. 2.

Skin lesions are often the first sign for an endocrine disease. Their description is thus of relevance for early diagnosis and treatment of endocrine disease for specialists in endocrinology as well as in dermatology.

Lavishly illustrated, this book describes the clinical and histological features of skin lesions observed in endocrine diseases. All features are reader-friendly structured and written in the language of dermatologists in order to enable a simple association between the features observed and the endocrine etiology.

This book provides cardiologists with access to the wealth of imaging from the Royal Brompton Hospital and National Heart and Lung Institute in London to enable them to improve on their own skills and refine their imaging technique. The authors correlate this echocardiography experience with the pathological and surgical aspects of congenital heart defects. They include a review of the pathologic, physiologic and surgical observations of different congenital diseases to assist in understanding the various echocardiographic presentations. The book contains large numbers of echocardiographic images.

Psychocutaneous Medicine offers an overview of diseases in psychosomatic dermatology and creates a bridge between cutaneous and emotional disorders using extraordinary illustrations and clinical images of psychosomatic dermatology. It covers both common and rare diseases and helps doctors and psychologists recognize and deal with psychosocial features in dermatology and venerology. This superbly illustrated clinical atlas with concise text passages follows the American diagnosis classification DSM-V and current evidence-based guidelines.

Developments in teleradiology are progressing at great speed. As a consequence, there is a need for a broad overview of the field. This first-ever book on teleradiology is presented in such a way that it should make it accessible to anyone, independent of their knowledge of technology. The text is designed to be used by all professionals, including radiologists, surgeons, nurses and allied health professionals, and computer scientists. In a very short time, driven by technical developments, the field of teleradiology has become too extensive to be covered by only a small number of experts. Therefore, Teleradiology has been written with chapter contributions from a host of renowned international authorities in teleradiology (see the Contents and the Contributors). This ensures that the subject matter focusing on recent advances in teleradiology is truly up to date. Our guiding hope during this task was that as editors of multiple chapters we could still write with a single voice and keep the content coherent and simple. We hope that the clarity of this book makes up for any limitations in its comp- hensiveness.

This book by Corey H. Evans, Russell D. White, and coauthorsis a gem. There was a time when exercise testing was largely limited to cardiologists, but no more. Ex- cise testing, which providesinformationon tness, the risk of coronarydisease, and all around vitality, is now being performed in the of ces of primary care physicians across the United States. Although there is a signi cant risk in some populations, a careful doctor who takes the trouble to become knowledgeable in exercise physiology and the pat- physiologyof coronary artery disease can use exercise testing to improve his ability to give excellent, preventive medicine. Over the years I have read many books on this subject, and even contributed to some, andthis oneratesrightup therewith the best.

The sober explanation for this book is a call by the Springer-Verlag, London, to edit a publication on 'The functional relevance of the collateral circulation' of the heart. Alternatively, it could be 'sold' as the result of my intention to reduce entropy of 18 years of scientific work on the topic of the coronary circulation, which was itself meant to diminish the amount of 'useless' energy. Such a process of reducing disarray in a system with the aim of grasping it better is related to simplification, which carries the risk of introducing error. This can be exemplified by the historic view of angina pectoris, which used to be simplified as being always fatal, thus obscuring for nearly two centuries the view of a 'self-healing' mechanism such as the collateral circulation of the heart. It would be na?]ve, to assume the present work to be free of erroneous oversimplification, because the very nature of scientific work is related to generating (simple) hypotheses with their subsequent falsification. In that context and bluntly, my primary interest in the field of the collateral circulation was not initiated with a vision of eradicating the consequences of coronary artery disease (CAD) by promoting the growth of natural bypasses. The time for such sizeable ideas had passed in the 1970s with the start of the work by Wolfgang Schaper."

Allergy is one of the major health problems of most modern societies. Although allergic diseases are well-known for almost two hundred years, their prevalence has increased dramatically over the last decades. Allergic reactions manifest in various organs, most commonly in the skin and mucous membranes, the frontier surfaces where the contact between the individual and the environment takes place. In a very concise and practical way this book covers all aspects of allergic reactions from pathophysiology to diagnosis, therapy and prevention with a strong focus on relevant aspects for the everyday work of the practising dermatologist and allergist in the hospital or office. This book reflects the rich personal experience of a German allergist with international training and reputation, who is active in immunology and allergy research and practice for almost 30 years. In this book, not only IgE-mediated allergic reactions are covered but all other kinds of allergies such as atopic eczema, contact dermatitis, drug eruptions, anaphylaxis and food allergies are equally represented as well as psychosomatic aspects and problems of environmental intolerances.

As essential a text for GPs as for dermatologists, this book is an atlas-like representation of the various forms of melanocytic skin lesions associated with cutaneous melanomas and other pigmented skin tumors. It is a comprehensive and up-to-date text on the practical issues surrounding the management of individuals with these lesions. It encompasses the classical methods of morphology such as the clinical and dermoscopic examination and dermatopathology. The book also deals with the most up-to-date diagnostic approaches such as laser scanning in-vivo microscopy and automated diagnosis. The visual atlas includes superb clinical, dermoscopic and histopathologic images.
