To date, diet programs and medical therapies for the treatment of obesity have had limited success. Bariatric surgery, however, provides a means of effective weight loss for many of those with morbid obesity. Most of these weight loss procedures are performed with a variety of techniques that continue to evolve. Each technique is associated with unique challenges and complications and it is important for the clinician to be knowledgeable about the endoscopic management of these patients. Additionally, as endoscopic technology evolves it may offer more than just the diagnosis and treatment of complications. Endoscopic therapy may soon allow less invasive bariatric revision procedures as well as a variety of primary obesity therapies for various patient populations. Bariatric Endoscopy reviews the management of obesity, normal post-surgical anatomy, endoscopic and medical management of post-surgical complications, and future endoscopic therapies for obesity management. Organized into five sections, the volume covers an obesity overview, traditional therapy, endoscopy and the bariatric patient, medical management of post-surgical complications, and the future role of endoscopy in obesity management. Detailed illustrations are also provided for surgical procedures, complications and obesity management chapters. Authored by authorities in the field, Bariatric Endoscopy is an indispensible tool for the gastroenterologist or surgical endoscopist as they care for patients with complicated bariatric issues.

Integrative Weight Management: A Guide for Clinicians intends to educate physicians and nutritionists about the wide ranges of approaches to weight control from non-traditional sources. The options for weight management in conventional practices are limited to a small number of medications, a confusing array of dietary approaches and surgical procedures with their inherent risks and complications. Unfortunately medical practitioners are not exposed to nutrition and weight control principles during training and thus are reluctant to manage their patients weight control issues. This volume is structured into 4 sections: Introduction to Weight Management Disorders; Morbidity and Mortality of Obesity; Therapy of Obesity; and Integrative Medicine and Obesity. Integrative Weight Management: A Guide for Clinicians represents a powerful collaboration of dozens of leading experts in the fields of nutrition, weight management and integrative medicine who have managed countless numbers of patients and summarized the research from thousands of articles to create an up-to- date state of the art guide for healthcare practitioners, allied health professionals and public health authorities who manage those who are overweight/obese along with the associated metabolic consequences.

Due to the latest developments in magnetic resonance imaging for the evaluation of liver pathology, a second, completely revised and enlarged edition of this book was felt necessary - despite only three years having elapsed since the first edition. All chapters from the first edition have been revised and enriched with additional illustrations and information. New chapters have been added covering important and highly relevant topics, among which imaging of pseudolesions, imaging of neoplastic diseases in pediatric subjects, imaging of bile ducts, MR angiography and imaging pre and post liver transplantation. Particular attention has been paid to the differential use of contrast agents with emphasis placed on the authors' broad experience of MR imaging of focal liver lesions using different contrast agents. The diverse mechanisms of action of all MR contrast agents applicable for liver imaging are explained in detail and comparative examples are provided. As was the case with the first edition, this book will prove invaluable to radiologists wishing to further expand or consolidate their routine approach to MR imaging of the liver.

"Approximately 65% of our population is overweight and 12% are morbidly obese. This is despite more than 25 years of attempted medical management. Clearly all current efforts have failed to control this enormous problem. Could it be that we have failed to recognize the cause of the disease and therefore have misdirected our efforts?" - Alfredo Fernandez, MD, FASMBS, Surgeon, Tampa, Florida Reducing obesity through bariatric surgery provides a sustainable weight loss regimen, because it restricts the size of the stomach and limits food intake. However, the surgery limits the amount of nutrients absorbed by the stomach and small intestine. This book provides a comprehensive, practical guide on pre- and post-nutrition considerations in bariatric patients. It describes surgeries including gastric bypass, lap band, and sleeve; nutrition protocols for surgery patients; pregnancy considerations- pre- and post-surgery; food consumption post-surgery; advancing healthy food intake after surgery; minimizing negative side effects; and recommendations to maintain healthy diet. This nutritional guide provides health care practitioners descriptions and answers to the many questions bariatric surgery patients need to know and ask in support group meetings and individual counseling sessions. The first chapter focuses on Selling Obesity and Food as a Cheap and Legal Drug, outlining how food advertising, portion size increases, and food frauds have contributed to the obesity crisis. New research into gut hormones, microbiome influence on obesity, firmicutes, and histamine are included, as well as pregnancy after bariatric surgery and lifestyle changes-eating, sleep, hydration, stress management-needed for success after surgery. Many health care practitioners will use the Post Op Discharge Diet stages of progression to explain how the patient needs to prepare for their liquid diet and overcome numerous issues like dumping syndrome, hypoglycemia, and alcohol and caffeine consumption. Diet plans for Ketogenic, Mediterranean DASH, Glycemic, and Low FODMAP are included within this book.

Pediatric Inflammatory Bowel Disease, Second Edition provides an essential reference with an emphasis on the unique pediatric issues of IBD. Chapters focus on complications of IBD specific to children and adolescents. Treatment recommendations are based on the latest clinical research available.

Thoroughly revised and updated from the first edition, the volumes includes new therapies that are currently being used or tested for treatment of IBD, important areas regarding incidence and prevalence, immunization and response to vaccine administration as well as advancements in our understanding of growth and development with particular to the use of growth hormone therapy. Other new areas covered include important topics of complementary and alternative medicine use in IBD, immunization, and liver disease in IBD. Pediatric Inflammatory Bowel Disease, Second Edition is a valuable resource for pediatric gastroenterologists as well as adult gastroenterologists.

Whereas most previous work on Maya healing has focused on ritual and symbolism, this book presents evidence that confirms the scientific foundations of traditional Maya medicine. Data drawn from analysis of the medical practices of two Mayan-speaking peoples, the Tzeltal and Tzotzil, reveal that they have developed a large number of herbal remedies based on a highly sophisticated understanding of the physiology and symptomatology of common diseases and on an in-depth knowledge of medicinal plants. Here Elois Ann Berlin and Brent Berlin, along with their many collaborators, provide detailed information on Maya disease classification, symptomatology, and treatment of the most significant health conditions affecting the Highland Maya, the gastrointestinal diseases. The authors base their work on broad-ranging comparative ethno-medical and ethnobotanical data collected over seven years of original field research. In describing the Mayas' understanding and treatment of gastrointestinal diseases, Berlin and Berlin show that the plants used as remedies are condition specific.> Moreover, laboratory studies demonstrate that the most commonly agreed upon herbal remedies are potentially effective against the pathogenic agents underlying specific diseases and that they strongly affect the physiological processes associated with intestinal peristalsis. These findings suggest that the traditional Maya medical system is the result of long-term explicit empirical experimentation with the effects of herbal remedies on bodily function.

This book provides up to date information about IBS and its developments in the last decade and provides ways of controlling IBS based on the authors' long experience in treating IBS patients. Although IBS is a tortuous disorder and interferes with the patients' daily activities, it does not develop into a serious disease or kill its sufferer. Understanding and learning ways of controlling IBS does not only help patients to lead normal lives, but also enables them to help their children and closest relatives.

This text provides a comprehensive review of the cytology of disease processes of the mediastinum and mediastinal lymph nodes with emphasis in lung and gut nodal cancer staging in specimens obtained by EUS-FNA. This book also reviews the cytology of intramural masses of the gastrointestinal tract using a pattern-based diagnostic approach. The cytomorphology of lesions obtained by EUS-FNA is peculiar by the common presence in the obtained sample of normal luminal gastrointestinal contents, and the cytopathologist should be familiar with this pattern not often seen when the sampling is done by percutaneous approach. Technical considerations pertaining to the operator performing the procedure as well as to the cytopathologist, with emphasis on rapid on-site interpretation are also covered. Most lesions described in the book also have endoscopic US image correlation. Cytology of the Mediastinum and Gut is a useful and practical guide for cytological interpretation and differential diagnosis of lesions obtained by EUS-FNA of mediastinum and gut. All chapters are written by experts with many years of experience in the field and contain the cytology, immuno-profile, molecular profile, and ultrasound features of the masses described.

Management of Functional Gastrointestinal Disorders in Children presents biopsychosocial theory with respect to six groups of functional disorders: disorders of elimination, vomiting disorders, abdominal pain, infant colic, chronic non-specific diarrhea of infants and toddlers, and failure to thrive. It illustrates, through numerous clinical examples, concepts of management developed during 45 years of practice. A satisfactory clinical outcome for pediatric gastrointestinal disorders often depends on the clinician's ability to discern not only the biological factors in illness, but also the unique cognitive and emotional needs that patients bring to the task of healing. This book provides guidelines for integrating the biopsychosocial model, an approach that has been under-emphasized in the literature until now. It includes naturalistic descriptions of functional gastrointestinal disorders, clinical goals, and the theoretical bases for management techniques. Offering numerous real-world examples and tips, this book serves as a valuable resource for pediatricians, family practitioners, pediatric mental health practitioners, pediatric nurse practitioners, as well as pediatric gastroenterologists.

Portal hypertension is the abnormal pathophysiologic state that develops in liver cirrhosis and certain other disorders with characteristic clinical and hemodynamic features. There has been great progress in our under standing and management of portal hypertension, particularly in the diagnostic and therapeutic approaches. The so-called Banti's syndrome, a disorder whose existence had long been questioned, is now a well-defined portal hypertensive disease. The recently introduced Doppler ftowmetry is currently yielding new information on portal hemodynamics. Endoscopic sclerotherapy and beta-blockers have come to be widely used in the man agement and prevention of variceal bleeding. In spite of all these advances, a number of unsolved questions remain, such as whether sclerotherapy, pharmacotherapy or surgery is warranted for prevention of bleeding, which is more effective as an elective treatment, the surgical or endoscopic approach, and whether surgical portacaval shunt should be totally replaced by selective shunt operations. These new developments and problems are clearly and comprehensively described and discussed by the foremost authorities in 44 chapters, which are divided into five sections: 1) Patho physiology, 2) Hemodynamic Investigations, 3) Imaging Investigations, 4) Clinical and Pathological Features, and 5) Esophageal and Gastrointestinal Bleeding. The primary goal of this monograph, to provide a framework of patho physiology of portal hypertension with authoritative descriptions of the clinical and laboratory manifestations of various portal hypertensive dis orders, has clearly been achieved by these excellent contributions.

As we approach the end of this millennium, enteric diseases remain impor tant public health problems. In many parts of the world, sanitary measures have advanced little over the last century, although some of the governments in those areas are striving to improve facilities for sanitation and to educate their people in proper handling of food, water, sewage, and other modes of transmission of pathogenic microbes. Even in highly developed countries, outbreaks of diarrheal diseases occur today. Globally, the annual morbidity from enteric infections is estimated at several billion and deaths at several million per year. In this volume, descriptions of some of these diseases, of immunity that results from them, of clinical studies that promote under standing of individual and community immunity, of molecular factors of pathogenesis, and/or of advances in vaccine development have been pro vided by leading researchers. At present, the application of molecular methods is enhancing the identification of protective antigens of many microorganisms. In addition, new methods for design and delivery of vac cines are being devised. Perhaps then more effective tools for reducing at least some of these diseases will be available within the next decade. Lois J.

This volume, the sixth of the series, represents the natural counterpart of the previous volume, Ultra structure of the Digestive Tract. Unlike the latter, however, whose contents fell entirely within the domains of gastroenterology, Ultrastructure of the Extraparietal Glands of the Digestive Tract encom passes a few cognate sciences, such as hepatology, pancreatology, and even oral biology, which are usually dealt with separately. This allows, starting from cell biology, embryology, and comparative anatomy, a comprehensive survey of organs that have much in common both structurally and functionally. The chapters of this book have been compiled by well-known experts in the field with the aim not only of reviewing and pointing out the state of the art of the subject covered, but also of giving directions for future work. Furthermore, through the integration of electron microscopy with immunocytochemistry, autoradiography, freeze fracture, maceration, enzymatic digestion, etc., and by providing superb illus trative material, the authors substantiate the pivotal role played by modern morphology in under standing human physiology and pathology. In fact, it must be stressed, that a consistent part of the tissues studied here are from human origin. We believe that this volume should be read, not only by scientists and teachers active in the field, but also by a larger audience of students and professionals interested in knowing the scientific foundations of biomedicine."

Systems Biology is a fast moving field. This accessible book uses the example of regulated exocytosis in pancreatic ss-cells, and its relevance to diabetes, to illustrate the major concepts of systems biology, its methods and applications.

It is easy to make anecdotal claims for the efficacy of new forms of treatment based on the short term results in a small number of patients. Many authors have done this for endoscopic laser therapy in the gastrointestinal tract. It is very much more difficult to carry out a comprehensive assessment of the short and long term effects of new techniques and to compare these with the results of alternative treatments for the same diseases. This book, from one of the world's leading departments of gastroenterology, describes and analyses the largest series of patients yet reported from one centre treated endoscopically with the NdYAG laser for gastrointestinal disease. The follow up extends over 8 years and the results are impressive. Some of the early claims for laser therapy have been validated, others have not, but the real value of the book is that we now have a large amount of well organised data on which to judge the merits of laser therapy. Medical laser techniques are in their infancy and the potential for future develop ment is enormous, but ideas on current applications have been consolidated and that is essential before the next concepts evolve. This book has taught us how to walk. The world is now ready to learn to run S. G.
