A fine team of state-of-the-art researcher/clinicians who know their fields, have contributed to the advancement of knowledge, and are in a position to judge what is truly important have here pooled their thoughts in a series of chapters on the cutting edges of gastroenterology. Four attributes render this volume superior to other update-oriented publications. The first striking feature, which is immediately evident upon scanning the table of contents, is the imaginative choice of subjects, ranging from trav eler's diarrhea and sexually transmitted GI infections through TPN and interventional endoscopy to geriatrics and iatrogenic disease. A second outstanding feature of this volume is its success in balanc ing basic pathophysiology with practical considerations of clinical man agement. This is achieved in the discussions of such diverse topics as acid-peptic diseases, infectious and other diarrheal syndromes, and hep atitis immunization. Throughout the book we are led smoothly from basic science principles to specific recommendations for diagnosis and therapy. This practical emphasis appears repeatedly and sometimes pro duces a delightful surprise, such as a chapter on radiology that is not tech nology-based but instead problem-oriented.
