Nutritional support of critically ill patients is a major treatment modality which will enhance recovery and shorten convalescence. New knowledge has emphasized that much of the organ dysfunction associated with sepsis and altered blood flow is related to oxidative injury. Specific nutrients are highly effective in counteracting these effects and their early administration may attenuate cellular damage and multi-organ failure. Patient outcome may also be enhanced by the route of feeding, administration of newer nutrient combinations, utilization of evolving methods of monitoring and the use of growth factors. This new knowledge has evolved to a new area of metabolic support which is addressed for the first time by a group of international experts. The topics presented and general conclusions are of major importance to the practitioners in this field, for they show, for the first time, a departure from the more traditional approaches of nutritional support in patients with life-threatening diseases.

Six members of the Herpesviridae family are human pathogens, including herpes and 2 (HSV-I and 2), Epstein-Barr virus (EBV), varicella zoster simplex virus I virus (VZV), human cytomegalovirus (HCMV), and human herpesvirus 6 (HHV 6). Each of these viruses is capable of causing distinct diseases of varying severity in children, young adults, and the aged. The diseases range from infection of epithelial tissue to the infection of internal organs and white blood cells. A common feature of the six pathogenic human herpesviruses is their ability to latently infect different cell types in which the viral DNA is not integrated and is unable to express its pathogenicity. Reactivation of the herpesviruses is a result of cellular processes which reactivate viral genes, leading to virus progeny and to signs of infection. Due to their ability to become latent after initial infection, once the pathogenic herpesviruses infect children they are maintained throughout life, having the potential of cause various diseases upon reactivation.

In spite of a long history of intense investigation the transmissible spongiform encephalopathies remain a poorly understood family of neurodegenerative diseases. This group of diseases has been described in a wide variety of animal species and includes kuru, Creutzfeldt-Jakob disease, and Gerstmann-Straussler syndrome in humans, and scrapie, bovine spongiform encephalopathy, and related syndromes in ruminants and rodents. In all cases spongiform degeneration and astrocytosis are seen in specimens of brain and a filterable transmissible agent is present in the brain and some other tissues of affected individuals. However, the precise nature of this agent remains unknown. Agent infectivity, which can so far only be assayed by serial transmission to new individuals, be remarkably resistant to inactivation has been shown to by heat, chemicals, and irradiation. These properties create significant biohazard possibilities during exposure to infected tissues. Transmission between humans was originally reco gnized in the unique epidemiology of kuru in New Guinea tribesmen, and concern about transmission from animals to humans has re-emerged as a result of the current epidemic of bovine spongiform encephalopathy in dairy cattle in Great Britain. Although interspecies transmission has often been achieved experimentally, its efficiency is highly variable. There fore, the possibility of spread of bovine spongiform encephalopathy from cattle to humans or various animal populations cannot be accurately predicted at this time. This volume presents a comprehensive update of know ledge concerning the transmissible spongiform encephalo pathies."

An up-to-date overview of acute and chronic pancreatitis. The two authors with special interests in this field deal with the aetiology, pathophysiology, and clinical features of these diseases, as well as complications, treatment strategies, and prognostic factors. Two chapters on congenital abnormalities and hereditary pancreatic diseases round off this book. Intelligently-structured for everyday practice, this can also be used as an actual reference book. For gastroenterologists in clinic and practice.

In recent years, the progress made in the prevention of mortality and morbidity caused by communicable diseases and malnutrition has changed the disease spectrum in both developed and, particularly developing countries. As a result, noncommunicable diseases, includ ing genetic disorders, have achieved considerable importance in public health. Furthermore, it is now evident that inherited predisposition is important in a number of common diseases that occur in later life, such as atherosclerosis, coronary heart disease, hypertension, diabetes mellitus, and in some rheumatic, oncological, and mental illnesses that appear at an early stage and develop into severe handicaps in predisposed people. Rapid advances in gene mapping concerned with international human genome research make it almost certain that the use of new genetic knowledge will dramatically increase the requirement for genetic approaches in the control of a wide spectrum of diseases, and will provide possibilities for their prevention and treatment in the form of changes in lifestyle, diet modification, periodic check-ups, or the administration of gene therapy. It appears that one of the main problems in delivering genetics services is the difficulty involved in informing the health profession and the community of the real sig nificance of genetic problems. There is, therefore, a need for international collaboration in improving genetic health education at all levels and in improving health through genetic approaches."

An insight into new advances of current interest in metal toxicology, such as mechanisms important in risk-assessment for human health. The book also has chapters on emerging conceptual problems including resistance to metal toxicity effects on gene expression, alongside principles regarding drug-chelation of metals, the potential use of prophyrins as indicators of metal exposure and toxicity. The toxicology of specific metals of major public health concern are discussed in depth, such as mercury, aluminum, arsenic, chromium, and cadmium. Of interest to basic scientists as well as public health administrators.

Now, in one volume, the latest research from the areas of molcular biology, neurochemistry and behavior analysis of drug abuse and dependence, with, wherever possible, an integration of the data from these various levels of analysis. The ensuing reports point to the complexity of the phenomenon of abuse and dependence and clearly demonstrate that it is determined by a variety of variables from molecular biology and genetics through behavioral history. This complexity is shown, however, to be responsive to rigorous scientific analysis and our success to date gives rise to hope that this distressing public health problem can ultimately be brought under control. Each of the chapters is written by a leading researcher in the field.

for the design of control programs; in extreme cases (as dis cussed below, by Fine et al., this volume, and elsewhere) it can happen that immunization programs, although they protect vaccinated individuals, actually increase the overall incidence of a particular disease. The possibility that many nonhuman animal populations may be regulated by parasitic infections is another topic where it may be argued that conventional disciplinary boundaries have retarded investigation. While much ecological research has been devoted to exploring the extent to which competition or predator-prey interactions may regulate natural populations or set their patterns of geographical distribution, few substan tial studies have considered the possibility that infectious diseases may serve as regulatory agents (1,8). On the other hand, the many careful epidemiological studies of the trans mission and maintenance of parasitic infections in human and other animal populations usually assume the host population density to be set by other considerations, and not dynamically engaged with the disease (see, for example, (1,2)). With all these considerations in mind, the Dahlem Workshop from which this book derives aimed to weave strands together -- testing theoretical analysis against empirical facts and patterns, and identifying outstanding problems -- in pursuit of a better un derstanding of the overall population biology of parasitic in fections. For the purpose of the workshop, the term "parasite" was de fined widely to include viruses, bacteria, protozoans, fungi, and helminths."

The very first international working discussion on slow infections of the nervous system was entitled "Slow, Latent, and Temperate Virus Infec tions" and was held at the National Institutes of Health (NIH) in December 1964. The primary impetus was the discovery and investigation of kuru in New Guinea by D. Carleton Gajdusek, M. D. This working discussion brought together investigators in human and veterinary medicine, virolo gists, microbiologists, and neuropathologists actively engaged in laboratory work with viruses that illustrated properties of latency, masking, slowness, or temperateness, with emphasis on subacute and chronic neurologic dis eases of unknown etiology. In the Preface to the monograph of published papers presented at the working discussion, Gajdusek and Gibbs wrote the following: After microbiology had given solution to the etiology of most acute infections of the central nervous system and after fungi and bacteria had been incriminated in impor tant chronic disorders of the nervous system such as torula and tuberculosis men ingitis, we have been left, in neurology, with a wide range of subacute and chronic affections of the central nervous systems of unknown etiology. Some of these diseases, still listed as idiopathic, are among the most prevalent afflictions of the central nervous system. Many others with familial patterns of occurrence do not yet have their basic pathogenesis or underlying metabolic defect elucidated, although we tend to think of them as genetically mediated."

In this exploration of the significance of illness in the Victorian literary imagination Miriam Bailin maps the cultural implications and narrative effects of the sickroom as an important symbolic space in nineteenth-century life and literature. Dr Bailin draws on non-fictional accounts of illness by Julia Stephen, Harriet Martineau and others to illuminate the presentation of illness and ministration, patient and nurse, in the fiction of Charlotte Bronte, Charles Dickens and George Eliot. She argues that the sickroom functions as an imagined retreat from conflicts in Victorian society, and that fictional representations of illness serve to resolve both social conflict and aesthetic tension. Her concentration on the sickroom scene as a compositional response to insistent formal as well as social problems yields fresh readings of canonical works and approaches to the constituent elements of Victorian realist narrative.

The book aims to review knowledge on the disorders of eating behaviour and body composition in some of the non-primate higher animals and to relate these to similar conditions in humans. With advances in understanding the nature of these disorders and their biological basis, it seems timely to assess what cross-species comparisons can tell us about the general underlying factors at work. This may also help to delineate what may be a general biological basis that humans share with their higher animal comrade species and what may distinguish human from non-human, particularly in a cultural context. This could help in combating better the problems of these conditions in the animal species as well as in man and in suggesting well-based preventive measures. As far as people are concerned the last two decades of the 20th century have shown a significant increase in obesity in the richer countries, particularly the USA (Table 1). Possibly associated with the obesity boom, there is an increasing awareness of other disorders of eating behaviour and body composition. These range from anorexia nervosa, at the other end of body composition to obesity, to others, such as bulimia, with more variable effects on body composition.

This book is designed to be a physician's guide for those interested in diving and hyperbaric environments. It is not a detailed document for the erudite researcher; rather, it is a source of information for the scuba-diving physician who is searching for answers put to him by his fellow nonmedical divers. Following the publication of The Underwater Handbook: A Guide to Physiology and Performance for the Engineer there were frequent requests for a companion volume for the physician. This book is designed to fill the void. Production of the book has been supported by the Office of Naval Research and by the Bureau of Medicine and Surgery, Research and Development Command, under Navy Contract No. NOOOOI4-78-C-0604. Our heartfelt thanks go to the many authors without whose contributions the book could not have been produced. These articles are signed by the responsible authors, and the names a e also listed alphabetically in these preliminary pages. Every chapter was officially reviewed by at least one expert in the field covered and these reviewers are also listed on these pages. Our thanks go to them for their valuable assistance. We are grateful to Marthe Beckett Kent for editing Chapter III. Our thanks also go to Mrs. Carolyn Paddon for typing and retyping the manuscripts, and to Mrs. Catherine Coppola, who so expertly handled the many fiscal affairs.

In the late eighties of the twentieth century I encountered a paper referring to mathematics dealing with imprecision applied to medical diagnosis. I was working in the area of medical statistics at that time, and obviously I was interested in the contents of the paper. After I had read it I became fascinated by new possibilities of medical data interpretation and processing proposed by the author. The new world of fuzziness, originated by Professor Lotfi Zadeh, seemed to open up to me and I started reading all accessible material about fuzzy set theory. Many years have passed since then. We are now living in the information so- ety and we do not experience troubles in reaching scientific material. Lately I have read many papers and books about treating medical tasks solved by using fuzzy ideas. I am still keen on tracing applications in medicine, and by myself I have been contributing to some concepts in this subject that has motivated me to p- pare my own book. The objective of writing such a book has been a little parti- lar, namely, I have intended to present the subject of fuzzy tools and techniques in medicine for eventual users. These, maybe representatives of medical or phar- cological staffs, are not expected to possess a large amount of mathematical knowledge.

This book provides a state-of-the-art, comprehensive overview of the diagnosis and treatment of sleep disorders.

The book offers a thorough and extensive board review for specialization in sleep medicine and supports primary care clinicians in appropriately using sleep diagnostic testing results in clinical practice.

It has never been easy to introduce new concepts and therapeutic in-terventions into surgical practice. When attempting to do so, one is faced with the interagency of traditional dogma, which still in this era of evidence-based medicine tends to dominate the surgical thought pr- ess. This is particularly so in the area of coloproctology, where prejudice and personal opinion often influence objective analysis whenever tradition is challenged. A large body of literature on anorectal prolapse has accumulated over the years; although much is based on personal viewpoint rather than scientific evidence, it has nevertheless been passed down through the generations as ac-cepted wisdom and practice. As a consequence, it is a challenge to change the mindset of a generation of surgeons and to introduce new concepts and novel techniques which at first might appear to be a radical departure from conventional teaching. It is obviously not possible to present the basis for the develop-ment of transanal stapling techniques for anorectal prolapse in this Foreword; this is dealt with in detail elsewhere in this book. The in-terested reader will have the opportunity to share in the new and emerging concepts surrounding anorectal prolapse and to deepen their understanding of the pat- physiology and basis for surgical correction. Although hemorrhoidal disease and external rectal prolapse have been known about for centuries, the understanding of internal rectal prolapse (intussusception) and rectocele has only really advanced with the emergence of radiological imaging tech-niques, such as defecography.

Translational Research and Clinical Practice offers a clear and comprehensive introduction to evidence-based medicine. The use of medical literature has always been an integral tool for patient care, yet recently the modern processes of question formulation, literature search, and study evaluation have changed with the advent of the internet and technology. The physician must be able to find empirical evidence from the appropriate study using a searchable question and then determine its impact on patient care. The book provides the general framework for such medical decision making; it covers all kinds of cases and strategies, including questions of diagnosis, therapy, prognosis, differential diagnosis, clinical presentation, and causality.
The tested material and approaches in this book are based on a course developed and taught by the author at Temple University School of Medicine. Organized for ease of use, accessibly written, and replete with clinically germane examples, Translational Research and Clinical Practice is a concise guide for medical students and clinicians seeking to effectively interpret and apply medical evidence in daily practice.

The Indian subcontinent is a vast land mass inhabited by over one billion people. Its rich and varied history is reflected by its numerous racial and ethnic groups and its distinct religious, cultural and social characteristics. Like many developing countries in Asia, it is passing through both demographic and epidemiological transitions whereby, at least in some parts, the diseases of severe poverty are being replaced by those of Westemisation; obesity, diabetes, and heart disease, for example. Indeed, as we move into the new millennium India has become a land of opposites; on the one hand there is still extensive poverty yet, on the other hand, some of the most remarkable developments in commerce and technology in Asia are taking place, notably in the fields of information technology and biotechnology. India has always fascinated human geneticists and a considerable amount of work has been done towards tracing the origins of its different ethnic groups. In the current excitement generated by the human genome project and the molecular and genetic approach to the study of human disease, there is little doubt that this field will develop and flourish in India in the future. Although so far there are limited data about genetic diseases in India, enough is known already to suggest that this will be an extremely fruitful area of research.

Few clinical disciplines have been transformed so dramatically by advancements in science and technology as gastrointestinal surgery. To begin with, modern ph- macology has virtually eliminated some kinds of surgery altogether. If one were to take a peek at a typical operating room schedule in a busy hospital of the 1960s, gastrectomies of one kind or another would have constituted a large block of the major surgeries. The advent of effective H2-histamine receptor antagonists and, more ] + recently, the H, K -ATPase (proton pump) inhibitors led to a precipitous decline in those procedures such that they are rarely performed today. Exciting new approaches to treating inflammatory bowel diseases and their complications-such as fistulas- with anticytokine therapy may one day have a similarly profound effect on surgery for this condition as well. Beyond pharmaceutics, advances in imaging techniques have greatly facilitated the identification and characterization of pathology in the gastrointestinal tract in a way that would have been unimaginable only a few years ago. Just to visualize the pancreas in some way was a horrendous task until abdominal ultrasound, magnetic resonance imaging, or computer tomography made it simple. The fact that the gut is a hollow organ that can be accessed through the mouth, anus, or even through the wall of the abdomen has been fully exploited with fiberoptic endoscopes that can bend around corners with ease and permit surgery to be conducted through them.

Authored by leading international researchers, this monograph introduces and reviews developed tomograhic methods for discovering 2D and 3D structures of the ionosphere, and discusses the experimental implementation of these methods.
