These proceedings of Falk Symposium 110 on `Intestinal Mucosa and its Diseases - Pathophysiology and Clinics' held at Titisee/Black Forest, Germany, 16-17 October 1998, comprehensively review salient clinical as well as scientific aspects - pending or settled - of the main intestinal diseases. In particular, chapters deal with infectious and neuroendocrine diarrhoeas, coeliac sprue, allergic enteropathy, intestinal lymphomas, colorectal carcinomas, and chronic inflammatory bowel diseases, in terms of clinical presentation as well as underlying mechanisms. This book therefore aims to bridge the gaps between basic science and clinics for the eventual treatment of patients afflicted with these diseases.
