This volume provides in a conveniently accessible package a comprehensive collection of accurate and timely information on the management of patients with diarrhea, both in pediatric age and in the adult. As medical knowledge has recently expanded in this area, this volume is full of new practical, clinically useful material for the busy clinician. Illustrations are emphasized to permit rapid acquisition of practical information that is not readily available in the major texts. Each chapter is concise, concentrating on 'clinical pearls,' and new advances in diagnostic and therapeutic technology. Each chapter discusses the relative costs of diagnostic and therapeutic options to permit financial considerations to be taken into account in the decision making process. Additional unique features include, summaries of key points, recommendations, and indications for requesting GI subspecialty consultation. Providing a comprehensive but practical overview of the issues surrounding the diarrheal diseases, this volume will prove of great value and utility to gastroenterologists, surgeons, internists, primary care physicians.
