Book Description
This collaboration of two physiologists and a gastroenterologist provides medical and graduate students, medical and surgical residents, and subspecialty fellows a comprehensive summary of digestive system physiology and addresses the pathophysiological processes that underlie some GI diseases. The textual approach proceeds by organ instead of the traditional organization followed by other GI textbooks. This approach lets the reader track the food bolus as it courses through the GI tract, learning on the way each organ's physiologic functions as the bolus directly or indirectly contacts it. The book is divided into three parts: (1) Chapters 1–3 include coverage of basic concepts that pertain to all (or most) organs of the digestive system, salivation, chewing, swallowing, and esophageal function, (2) Chapters 4–6 are focused on the major secretory organs (stomach, pancreas, liver) that assist in the assimilation of a meal, and (3) Chapters 7 and 8 address the motor, transport, and digestive functions of the small and large intestines. Each chapter includes its own pathophysiology and clinical correlation section that underscores the importance of the organ’s normal function.

Book Description
Three distinct types of contractions perform colonic motility functions. Rhythmic phasic contractions (RPCs) cause slow net distal propulsion with extensive mixing/turning over. Infrequently occurring giant migrating contractions (GMCs) produce mass movements. Tonic contractions aid RPCs in their motor function. The spatiotemporal patterns of these contractions differ markedly. The amplitude and distance of propagation of a GMC are several-fold larger than those of an RPC. The enteric neurons and smooth muscle cells are the core regulators of all three types of contractions. The regulation of contractions by these mechanisms is modifiable by extrinsic factors: CNS, autonomic neurons, hormones, inflammatory mediators, and stress mediators. Only the GMCs produce descending inhibition, which accommodates the large bolus being propelled without increasing muscle tone. The strong compression of the colon wall generates afferent signals that are below nociceptive threshold in healthy subjects. However, these signals become nociceptive; if the amplitudes of GMCs increase, afferent nerves become hypersensitive, or descending inhibition is impaired. The GMCs also provide the force for rapid propulsion of feces and descending inhibition to relax the internal anal sphincter during defecation. The dysregulation of GMCs is a major factor in colonic motility disorders: irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and diverticular disease (DD). Frequent mass movements by GMCs cause diarrhea in diarrhea predominant IBS, IBD, and DD, while a decrease in the frequency of GMCs causes constipation. The GMCs generate the afferent signals for intermittent short-lived episodes of abdominal cramping in these disorders. Epigenetic dysregulation due to adverse events in early life is one of the major factors in generating the symptoms of IBS in adulthood.

Book Description
This casebook provides a concise yet comprehensive state-of-the art review of common stomach and small intestine disorders. The casebook is divided into five parts, each of which focuses on a major disorder, symptom, or clinical scenario related to the stomach and small intestine, including dyspepsia, small bowel disorders, nausea and vomiting, chronic abdominal pain, and post-operative GI surgery challenges. Each part is comprised of cases illustrating different aspects of the subject, with each case containing sections on case presentation, objectives, epidemiology and etiology, diagnostic evaluation and treatment, case follow-up, clinical pearls, and Q&A. Some major topics presented in these cases include nausea and vomiting in the pregnant patient, gas-bloat, functional abdominal pain, post-GI surgery complications, and celiac disease and non-celiac gluten sensitivity. Written by internationally renowned experts in the field, Essential Medical Disorders of the Stomach and Small Intestine: A Clinical Casebook is a valuable resource for clinicians and practitioners who treat patients afflicted with disorders of the stomach and small intestine.

Book Description
Gastrointestinal endoscopy is now mainstream and the focus is nowchanging from developing new techniques to enhancing the efficiencyand quality of fundamental techniques. There are three elements tothis agenda: initial training, continuous quality improvement andpatient empowerment. For the first time, the book is accompanied by two CD-ROMs -featuring video and animation of how to perform the techniques. Thefirst CD-ROM covers the upper GI tract and consists of twosections: (1) the background to instruments and how to get set up,and (2) how to perform diagnostic techniques. The second CD-ROMcovers diagnostic and therapeutic procedures in colonoscopy. Cotton and Williams' book has evolved with each new edition toreflect developments in the field of endoscopy over the last 20years. This fifth edition draws on the vast experience of the authorsand heralds current changes in both endoscopy and publishing. The emerging 'back to basics' attitude of endoscopy opinionformers with regard to the teaching of endoscopy has resulted in amore focused table of contents specifically targeted at newcomersto this specialty.

Book Description
Food research (and funding) is becoming more and more focused on health. While researchers and product developers have made great strides in food engineering, there needs to be increased focus on what happens when the food is actually digested. How is the food absorbed? Do the benefits remain? Digestion is a complex topic, and this will be the first book aimed at food researchers. Authored by a physiologist and a food engineer, the book will be a welcome addition to the literature.
