Gastrointestinal diseases are the leading causes of morbidity and mortality in clinical practice with diarrhea and abdominal pain accounting for over 50% of the symptoms that patients present to their doctors. It is therefore not surprising that many of the chapters in this book are on diarrhea and acute or chronic abdominal pain. The chapters have been written by world renown experts in their respective fields, all of which are related to gastroenterology. Dr. Saulius Paskauskas has covered the area of adult intussusceptions, Prof. Azevedo et al write about prospective uses of genetic engineering, while dysbiosis of intestinal microbiota in irritable bowel syndrome has been very well covered by Dr. Anna Lyra and Dr. Sampo Lahtinen. Other interesting titles like perforated appendicitis, travelers’ diarrhea and management of various gastrointestinal conditions are some of the topics presented in simple and accessible language with well labeled illustrations where appropriate. Advances in the pathophysiology and treatment of postoperative ileus has been covered by Dr. Tropskaya and Dr. Popova, with evidence based on experiments carried out in animal models, while Prof. Yvette Tache et al ably handle modulation of visceral pain by stress implication and modulation. The later is a must read for all professionals as it utilizes simple theories to explain some of the recurrent symptomatologies that patients present with. This book will form useful reading for the inquisitive undergraduate medical student who wants to read more about the pathophysiology of various gastrointestinal diseases such as intussusceptions but also offers detail to the specialists out to explain causes and management of various conditions such as acute and chronic diarrhea. Most of the chapters have an introduction and objective, epidemiology, clinical presentation and investigation sections, with outlines on management and X Preface conclusions at the end. They have been presented in this way to make them easy to understand and for quick reference by the reader while in the clinic or classroom in these days of pressure for answers and maximum time constraint. To the reader, we hope that this book will offer you the right knowledge that would favorably modify your approach to problems of the gastrointestinal tract in the future.
