The development and improvement of new technologies have made pancreatic disease more accessible to diagnosis in the last decade. The cooperation and coordination of experts in the fields of gastro enterology, radiology, biochemistry, immunology, and pathology are necessary if the methods are to be made available and the progress made to be fully exploited. Each of the new methods requires special training, and extensive experience is needed to guarantee high standards in the diagnosis of pancreatic disease. New methods have to be tested carefully against established diagnostic procedures, though at the same time we must be ready to adopt a new approach to diagnosis. The aim of this book is to update the material already published and to focus on the various imaging methods and functional tests currently available, the features specific for each, and their integrative potential in the detection of pancreatic disease. The various pathologic findings are analyzed with reference to the clinical stages of pancreatic disease. As an introduction to the morphological and functional features of acute pancreatitis, chronic pancreatitis, and pancreatic cancer revealed by the different imaging methods and functional tests, basic knowledge of the patho-physiological and pathomorphological events is provided by research workers. This knowledge is essential for the understanding and interpretation of the diagnostic findings recorded in pancreatic diseases.

Physicians treating patients with Inflammatory Bowel Disease (IBD) often face challenges due to the disease itself, associated conditions, and systemic effects. Recently, new medications have been introduced that allow for more aggressive and effective treatment of IBD. With these medications come the risks of adverse side effects, and physicians must vigilantly monitor for any complications. Drs. Miguel D. Regueiro and Jason Swoger have created a unique, user-friendly book that describes how to prevent, recognise, and manage complications encountered in the care of patients with IBD. Clinical Challenges and Complications of IBD aims to provide practical and clinically oriented information to assist physicians with commonly encountered complications of the natural history of IBD, extraintestinal manifestations of IBD, general health and metabolic complications of IBD, and complications arising from both the medical and surgical treatments of IBD. Formatted to allow for quick access of the information, Clinical Challenges and Complications of IBD is organised into sections that allow physicians to both identify potential pitfalls in treatment, as well as focus on health maintenance and specific challenges, including pregnancy, nutrition, and psychological issues. Clinical pearls will be emphasised and each chapter will provide a bulleted summary, along with suggestions for future reading. Clinical Challenges and Complications of IBD is an invaluable guide for gastroenterologists, nurse practitioners, physician assistants, and gastroenterology trainees as it is a one-of-a-kind resource for recognising and dealing with the challenges and complications in patients with IBD.

The original series, Advances in Prostaglandin Research, edited by Sultan M. M. Karim, was published by MTP Press in three volumes in 1975 and 1976. A glance at those books illustrates the progress that has been made since then. The thromboxanes were mentioned twice (first publication 1975) and prostacyclin not once (first publication 1976); leukotrienes were only on the horizon. The amazing generation of research data in the last 10-15 years has given new, broad insights into many areas, including asthma, inflammation, renaL cardiovascular and gastrointestinal diseases and in reproduction, and has led in some instances to real clinical benefit. This series, AdvancesinEicosanoidResearch, reflects the current understanding of prostaglandins, thromboxanes and leukotrienes. The aim is to provide an introductory background to each topic and the most up-to-date information available. Although each book stands alone, the eicosanoids cut across many boundaries in their basic actions; selected chapters from each book in the Series will provide illuminating and productive information for all readers which will advance their education and research. In the production of this series, I must acknowledge with pleasure my collaboration with editors and authors and the patient endeavours of Dr. Michael Brewis and the staff at MTP Press

This book is a gift from the international community of amyloid friends, presented to Professor Dr. Enno Mandema on the occasion of his retirement from the University of Groningen, the Netherlands. It is the "precipitation" of up to date knowledge of amyloidosis, as presented at the International Course on Amyloidosis in Groningen, on the 10th and 11th of October 1986. Twenty years ago, Professor Mandema invited a group of scientists, who were studying the various aspects of amyloidosis from different points of view, to discuss their mutual interest in the subject. This "First International Symposium" was held for five days in September 1967. It was a wonderful experience for the participants, as most of them had until then only read each others work in the literature. The proceedings of that symposium, which contained the "lively" dis cussions, became a text-book for the following years. Research continued, and while the book was still in preparation, the revolutionary method of "water-soluble amyloid" was published. In the following years, different amyloid proteins were discovered and the mo lecular basis of the different amyloid syndromes was elucidated. The increase in knowledge parallelled the availability of modern, ingenious and also rapid methods in the biomedical sciences."

The "Evidence-based Practice Workbook" is an ideal tool for use by GPs, medical specialists and other healthcare professionals to learn the concepts of evidence-based practice (EBP). Practical and interactive, this workbook provides simple methods to help health professionals find and use the best evidence to answer clinical questions, developing their skills in:
asking clinical questions
searching for answers
discriminating good from poor information and research
using the answers to make clinical decisions.

This attractive, colour workbook provides a clear explanation of EBP skills and concepts. Written by internationally respected authors, this expanded and updated edition has been developed from evidence-based practice workshops run by the Centre for Evidence-Based Medicine at the University of Queensland and Oxford, and contains information and exercises to help health professionals learn how to use EBP in their clinical practice.

Hepatic cells are involved in the metabolization and elimination of a variety of endogenous and exogenous substances. They mediate the uptake, processing and subsequent secretion of biliary compounds, such as various drugs or hormones, and the passage of metabolites to be released into different blood compartments. To perform vectorial passages hepatocytes show a strong polarity with sites for endocytotic processes or specific carrier molecules, and a specified system of organelles for intracellular transport and sorting, metabolization and secretion of compounds. Several aspects, e.g. regulation, control and mechanisms of hepatic traffic are reported in detail - complemented by methodological approaches to analyse and monitor these processes.

In offering this book to what we hope will be interested readers, we have several aspirations. We have aspired to present to students and clinicians a rather narrow view of epidemiology concentrating on the causal factors and setting of the more usual gastroenterological problems and giving greater space to conditions of importance for which major knowledge of causation andcourse is available. Part of the rationale is thebelief that modern medicine lays excessive emphasis on therapy with increasingly expensive, and in many cases, dangerous drugs and too little emphasis on the causes and avoidance of disease. We are of the view that traditional views handed st down through generations of clinicians need scrutiny worthy of 21 century medicine whose currency includes topics like nanomoles, megabytes and logistic regression. We hope that clinicians will see that there is often a practical application to the findings of epidemiological exploration and that what passes for canonical knowledge is so often unsubstantiated myth and are fully aware of the reluctance of organized medicine to reject old paradigms in favor of the new, matched by an often uncritical enthusiasm for new therapies. Our researches have increased our belief in the major role of social factors especially diet, both in quantity and quality in many disorders and that clinicians have a responsibility to provide appropriate advice to policy makers as well as patients.

This work has true international scope, being a unique European/American joint venture that focuses on the state of the art in both diagnostic and therapeutic radionuclide methodology. Pertinent clinical applications are emphasized rather than attempting to cover everything included in the several large comprehensive texts available in our field. This "practical" approach should make it an essential guide to nuclear medicine physicians, technologists, students and interested clinicians alike.

1 2 MARCEL B. ROBERFROID AND GLENN R. GIBSON 1 Universite Catholique de Louvain, Department of Pharmaceutical Sciences, Avenue Mounier 73, B-1200 Brussels, BELGIUM 2 Food Microbial Sciences Unit, Department of Food Science and Technology, The University of Reading, Reading, UK It is clear that diet fulfils a number of important human requirements. These include the provision of sufficient nutrients to meet the requirements of essential metabolic pathways, as well as the sensory (and social) values associated with eating. It is also evident that diet may control and modulate various body functions in a manner that can reduce the risk of certain diseases. This very broad view of nutrition has led to the development of foodstuffs with added "functionality." Many different definitions of functional foods have arisen. Most of these complicate the simple issue that a functional food is merely a dietary ingredient(s) that can have positive properties above its normal nutritional value. Other terms used to describe such foods include vitafoods, nutraceuticals, pharmafoods, foods for specified health use, health foods, designer foods, etc. Despite some trepidation, the concept has recently attracted much interest through a vast number of articles in both the popular and scientific media.

This totally revised and enlarged new edition offers concise and well-structured chapters each focusing on the clinical, diagnostic, and therapeutic aspects of a condition commonly encountered by the coloproctologist and gastroenterological surgeon, who are faced with an increasing number of precise and specific treatment modalities. The comprehensive, yet easy-to-read, information in this practical guide on both common and rare anorectal and colonic diseases is particularly important for both the practitioner, who needs to know all the possible modalities of conservative and surgical treatment, and the surgeon, who needs to adapt his surgical procedure to the clinical and anatomical findings. Precise guidelines are given and surgical techniques illustrated. Each chapter is completed with up-to-date references and a self-assessment quiz, and a DVD is included.

A complex disease entity, intestinal failure (IF) has only recently become accepted as a distinct clinical syndrome. Improvements across a wide range of disciplines-including critical care and organ transplantation as well as surgical, medical, and nutritional therapies-have led to a steady rise in survival and quality of life for patients with IF. Taking a current, multidisciplinary approach to their care, Clinical Management of Intestinal Failure offers intensive discussion of medical and nutritional issues in adults and children with intestinal failure. It addresses all facets of IF, including epidemiology, clinical presentation, intestinal rehabilitation, and transplantation. Topics covered include: Etiology and epidemiology Pathophysiology and clinical assessment Medical and surgical management Prevention and treatment of complications Nursing management Emerging diagnostic and therapeutic methods Long-term care Reflecting the diverse nature of IF clinical care and research, this book is written by a group of expert clinician scientists that includes gastroenterologists, surgeons, nurses, pharmacists, dietitians, social workers, and patients. They show how a multidisciplinary approach to patient care is instrumental in achieving optimal patient outcomes through more efficient lines of communication, improved monitoring of medications and their effects, detailed evaluation of growth parameters, and facilitation of the creative process that can lead to research breakthroughs. Advancing the discipline of IF, this book summarizes the current state of the art of patient management as well as new developments in the science of tissue engineering, medical and surgical therapy, and transplantation.

While the gastrointestinal tract ingests, digests, and absorbs nutrients, the liver transforms nutrients, synthesizes plasma proteins, and detoxifies bacteria and toxins absorbed from the gut. It is therefore not surprising that gastrointestinal and hepatic diseases have a major impact on the nutritional state of the individual. Integrating nutrition and the gastrointestinal system, the Gastrointestinal and Liver Disease Nutrition Desk Reference brings together experts in the field of nutrition, gastroenterology, and hepatology to offer dietary, nutritional, and natural therapies for gastrointestinal and hepatic ailments in order to improve overall health. Providing a review of the digestive tract, liver, and core concepts, this important reference presents the nutritional consequences and considerations of digestive disorders. Contributors examine the role of nutrition in gastrointestinal and liver disease, including alcoholic and nonalcoholic liver disease, viral hepatitis, cirrhosis, malabsorption, colorectal disease, transplantation, pancreatitis, and inflammatory bowel disease. Of special interest to the practitioner are chapters on food allergy and intolerance, the effects of medicinal plants, and the role of fiber in the gastrointestinal tract. The reference also addresses the challenges of managing nutritional issues for hospitalized patients and covers eating disorders and ethical issues. Other key topics include: Obesity Clinical applications of probiotics The impact of micronutrient deficiencies Genomic applications for gastrointestinal care Drug-drug and drug-nutrient interactions Guidelines for performing a nutrition assessment This comprehensive reference offers a toolbox of key concepts, charts, tables, algorithms, and practical therapeutic strategies for practitioners involved in gastrointestinal and hepatic nutrition care. Dr. Mullin maintains a website discussing the integration of both Eastern and Western (conventional) medicines to help patients overcome their digestive illnesses.

This book, the proceedings of Falk Symposium 152 a oeEndoscopy 2006 a" Update and Live Demonstrationa, held in Berlin, Germany, 4--5 May 2006 as part of the Intestinal Disease Meeting, provides an update on the entire spectrum of gastrointestinal endoscopy and its interface with gastroenterology as well as other disciplines. Endoscopy plays a pivotal role in gastroenterology and, vice versa, is crucially dependent on new developments and inventions in gastroenterology and basic sciences as well as technical progress.

The first section deals with the most relevant new technologies including conventional and novel endoscopic imaging as well as new developments in therapeutic gastrointestinal endoscopy, pancreatobiliary endoscopy and ultrasound. The second part highlights the role of endoscopy in special areas, e.g. inflammatory bowel syndrome or pediatrics. Therapeutic endoscopy of biliary and pancreatic diseases is often difficult and involves risks. The third section contains papers on hilar tumors and chronic pancreatitis.

Prevention and adequate management of complications is the topic of the final section. It is important to maintain high standards in interventional endoscopy. Complications can arise when patients are sedated, which is mostly the routine in daily endoscopic practice; during dilatation of gastrointestinal strictures perforations can occur or endoscopic retrograde cholangiopancreatography may result in post-interventional pancreatitis.

Continuous technical developments of radiological imaging techniques have not only improved the potential of organ-based radiological diagnostics, but now also allow for dedicated whole-body exams which may be used in the field of screening and preventive diagnosis. The concept of this book is to provide clinicians with a broader understanding of screening and preventive diagnosis using radiological imaging. The first part of the book is dedicated to the fundamentals of screening and preventive diagnosis, and will comprise chapters on epidemiology and pathology, technical and organizational aspects of radiological screening, and chapters on legal issues and cost-risk analysis. The second part of the book will discuss the most important practical examples of radiological screening and surveillance, both for unselected populations, as well as for individual risk groups.

This book, written by leading experts from many countries, provides a comprehensive and up-to-date description of how to use 2D and 3D processing tools in clinical radiology. The opening section covers a wide range of technical aspects. In the main section, the principal clinical applications are described and discussed in depth. A third section focuses on a variety of special topics. This book will be invaluable to radiologists of any subspecialty.
