Clinicians spend their working lives making decisions. such decisions are usually made in interlocking streams rather than in the discrete circumscribed contexts so beloved of scientists. When the clinician encounters a patient a complex interactive process is initiated in which the clinician searches his memory to match the symptoms and signs indicated by the patient with the complex disease models which he carries in his head. He then makes choices about further questions or tests in order to clarify his understanding of the patient's problem and to formulate a management or treatment plan. In recent years there has been increasing interest in how clinicians make such decisions and a realization that decision-making in clinical medicine is virtually the same as that in many other professional contexts. The scientific study and formal teaching of clinical decision-making is a relatively young discipline. Less than 20 books have so far appeared which take explicit account of the theoretical and experimental decision-making literature in medicine and other related disciplines. This book is a distinctive and important contribution to this growing field. It combines a comprehensive critical analysis of a wide range of relevant philo sophical, statistical, psychological and medical literature with an interesting set of experimental observations of primary care physicians. Dr. Ridderikhoff shows great erudition and wide command of a large reference literature. Dr. Ridderikhoff takes a firmly descriptive rather than prescriptive viewpoint on understanding clinical decision-making."

Decoding the significance of proteinuria as an indicator of severity or prognosis in kidney disease is a stimulating challenge to students and practitioners of nephrology. Sir Richard Bright in 1827 associated pro with the disease that bears his name. In the subsequent more teinuria than a century and a half, however, the meaning of the linkage between proteinuria and renal disease remains elusive. Proteinuria is discovered on routine urinalysis in about 10 million Americans, most of whom express no symptoms of kidney disease, each year. From the studies of Robinson (updated in these pages), we know that proteinuria, per se, can be present for 20 years without change in re nal function, as described in orthostatic proteinuria. By contrast, pro teinuria may be the harbinger of swift kidney destruction, rarely cul minating in clinical collapse, a syndrome typifying "malignant proteinuria" as detailed herein by Avram. Although proteinuria is ubiquitous, an orderly management strategy for rational handling of proteinuria of less than nephrotic range is lack ing. Separation of tubular proteinuria and transient proteinuria of fever is now possible routinely. This book provides a record of the contribu tions of investigators and clinicians whose work forms the substrate for production of understanding and, ultimately, marching orders for prac titioners seeking optimized management for their proteinuric patients."

The author has organized basic, core information on the diagnosis, treatment and prevention of chemical dependence into a readily understandable format. His approach teaches the physician what steps to take from a practical point of view: how to prevent addiction in the first place, how to diagnose the condition, how to aid the family get the addict into treatment, and how to increase the chances of long-term recovery. The book is divided into three sections. The first section covers basic definitions and concepts. The second section describes the pharmacology of the various psychoactive substances: depressants, opioids, stimulants, cannabinoids, hallucinogens, phencyclidines, and inhalants. The third section discusses chemical dependence in special groups: women, adolescents, the elderly, ethnic minorities, dual diagnosis patients, HIV- positive patients, and impaired physicians.

Preventing Disease, the offspring of an extraordinary collaboration between the U.S. and Canadian Preventive Services Task Forces, presents a meticulous and objective review of the published evidence on preventive measures. Examining such diverse and relevant topics as screening for endometrial cancer, exercise counselling for healthy adults, and the evidence for a causal relation between dietary lipids and coronary heart disease, this volume reflects the editors' shared conviction that recommendations for preventive action should rarely exceed what is well justified by the evidence. In the current period, characterized as the Second Public Health Revolution, the authors' hard-nosed approach leads them to ask the tough questions. Are preventive measures cost-saving? Does preventive screening actually lead to treatment in clinical practice? Does the treatment do more good than harm? To what extent does our desire to eliminate causes of serious disability, ill health and premature death cloud our objectivity? All concerned about preventive medicine, community health, and primary care will find valuable stimulation for thought and action in this book: the contributions have gone beyond the rhetoric.

An ever greater number of our contemporaries will reach a very much greater age than their ancestors. Longevity is one of the most fertile fields for paradoxes: it is clear that the same causes do not produce the same effects at the age of ten and at the age of one hundred! On the subject of longevity, the "recipe book" is far from having been written. Nevertheless, the Fondation IPSEN has chosen a few of these paradoxes to discuss and try and explain them.

Pelvic pain in the female patient is common in gynaecological practice, but the specialties of general surgery, urology and orthopaedics provide a significant number of patients and problems. These patients may suffer a multitude of symptoms, and only careful analysis and investigation of each individual problem by the doctor concerned will lead to correct diagnosis and management. The subject matter of this book lies in the practice of many specialties, and all are combined here in a coherent whole. This emphasises the close collaboration necessary between family practitioners, junior hospital staff and consultants. The authors are consultants who work together in a busy district general hospital, and their experience and collaboration is evident in the approach to the diagnosis and management of pelvic pain in the female. Emphasis is laid on the careful evaluation of history and examination and the correct interpretation of diagnostic investigations. Full details of radiology, ultrasound scanning, endoscopy, peritoneoscopy and bacteriological investigation are given. Full consultation between members of staff who have special experience in these investigative procedures is of paramount importance. Details of treatment for relief of pain are important to all doctors concerned with this aspect of clinical management. and this section will be of particular value. The blending of these specialties allows full consideration of the problems affecting the patients. Careful management leads to better treatment for the patient and better satisfaction for the doctor.

There is now widespread recognition that emotional problems, to say nothing of the interactions of emotions with other manifestations of illness and disease, constitute a substantial component of all human suffering. For too long the pro vision of medical care has been restricted to the physical aspects of that suffer ing while the psychological aspects have been shunned. Whether through igno rance about the nature of emotional illness and its clinical management, or through uncertainty about the legitimacy of their ministrations, physicians and many other health professionals have left the care of psychiatric problems to psychiatrists and other mental health professionals. For a variety of reasons this strategy is no longer feasible and substantial changes are required. The extent of the needs, the nature of the presenting problems, the ex pectations of the patients, the prohibitive costs of alternative approaches, and the lack of trained mental health professionals make it imperative that general health workers learn to cope with the psychological and behavioral health prob lems of their patients. There are no other alternatives if the realities of comtem porary suffering, limited resources and psychobiological knowledge are accepted. It is to the pragmatic knowledge base for this essential component of contemporary health care that this book makes a seminal contribution. Dr."

The Fourth International Congress of Peritoneal Dialysis was held in Venice, Italy, June 29 to July 2, 1987. By this time peritoneal dialysis had emerged as a treatment for a substantial fraction of patients with end-stage renal disease and countless numbers of patients with acute renal failure. This treatment is now practiced worldwide and is the life-sustaining treatment for about 40,000 patients with chronic renal failure, representing 15 to 20% of dialysis therapy in about 1000 centers. It is not surprising, therefore, that the number of health professionals engaged in the investigation and the application of the treatment has also grown exponen tially. The First International Symposium on Peritoneal Dialysis, organized by Dr. A. Treviiio-Be cerra in Chapala, Mexico, in 1978, brought together a group of pioneers when continuous ambulatory peritoneal dialysis was in its infancy. In 1981, Dr. G. M. Gahl chaired the Second Symposium, in West Berlin, when the technique and professional interest were growing con siderably. By 1984, when Dr. 1. F. Winchester and I organized the Third Symposium, the pre sented papers exceeded 100 and there were about 1000 attendees. At that time, it was deemed appropriate to form a more organized group and the International Society for Peritoneal Dialy sis was founded. One of the first actions of the Society was to choose from among several applicants Dr."

Following an introduction to the philosophical and theoreti- cal background of traditional Chinese medicine, the dia- gnostic system is presented: the Chinese system of channels and functional organs, the significance of pointsand point categories, methods of needling and moxibustion. There is a chapter on treatment based on western diagnosis.

Comprehensive Management of Menopause is a balanced, authoritative, and state-of-the-art approach to the treatment of all medical issues of the menopausal patient, strongly emphasizing clinical and practical applications for comprehensive care.

Comprehensive Management of Menopause is the definitive text comprising all aspects of menopause and is indispensable to every physician providing medical care to women.

Although dyspepsia has been investigated for a long period of time, there is no international agreement on what constitutes this condition nor any standardized guidelines. National guidelines followed by practitioners in different countries vary in diagnostic and therapeutic approach, underlining the necessity for a unique definition worldwide. Dyspepsia in Clinical Practice summarizes the current guidelines while offering a unified, practical definition of dyspepsia, and a diagnostic algorithm with an emphasis on the upper gastrointestinal endoscopy and rational first-line therapeutic approach based on epidemiology, pathophysiology, clinical presentation, diagnostic workup and response to previous therapy. Up-to-date scientific information about dyspepsia is presented from a practical, clinician's point of view. Written by experts in the field, this volume addresses dyspepsia in childhood and in the elderly, a very important issue often insufficiently emphasized in the literature. Guidelines are provided that can be easily followed in clinical practice, leading to a reduction in costs and increased patient safety. Dyspepsia in Clinical Practice will be of great value to gastroenterologists, internists, primary care physicians, pediatricians, infectious disease specialists, residents and fellows in training.

Based on the Commonwealth Harvard Alcohol Research and Teaching Program, this clinically oriented work is designed to give internists and primary care practitioners the knowledge and skills necessary to recognize and care for patients with alcoholism.

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."

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."

This unique and authoritative book presents an up-to-date overview of the many aspects of energy balance and its relationships to disease processes resulting from excess energy consumption and storage. It provides a comprehensive treatment of important research and clinical aspects of energy metabolism and obesity. It will be a valuable resource for endocrinologists, diabetes specialists, internists and family practitioners.

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.

Recognizing the clinician's need for quick access to a comprehensive and immediately useful presentation of evidence-based material, the authors and editors have condensed the research on the most common otorhinolaryngological complaints into this indispensable volume. Their unique approach color-codes the level of research backing each set of evidence in order to make assessment of the evidence as quick and useful as possible. Each clinical problem is presented with a "color key," letting the physician know the level of evidence available: green (high-level evidence), yellow (low-moderate levels of evidence), or red (major disagreement or only minimal low-level evidence). The content of each chapter is structured in the same manner so the reader quickly becomes accustomed to finding precisely the information needed for each new case.

Featuring sections on general otolaryngology, head and neck surgery, pediatrics, and otology, Evidence-Based Otolaryngology not only presents the research, but gives the clinician immediately applicable recommendations for patient treatment.

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.

1 Historical Introduction INTRODUCTION This chapter is mainly about the history of medicine and its ethics. As usually c- ceived, history is retrograde: It is what happened yesterday, and, much as we may try, it is what happened yesterday seen with a set of today's eyes. Trying to understand yesterday's culture may help us put on a pair of corrective glasses, but it fails in - tirely correcting our vision. Contemporary cultural anthropology may likewise help us understand the way today's events and cultural habits shape what we call history tomorrow. Past events and the kaleidoscopic pattern of today's cultures may help guide us into a future that in at least some respects is ours to forge. Learning about ethics yesterday and thinking about ethics as it expresses itself in various cultures today can help us shape the ethics of tomorrow: This is true whether we are speaking of that part of social ethics called "medical" or of any other part of social ethics. The social aspects of medical practice-how the institution called medicine fits into and works within the greater society called culture-shape the way its ethics ultimately must play itself out.

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.
