Authoritative new text from the experts in GI populationstudies This book covers both key methodological issues and the mostimportant information in the field, disease by disease. It focuseson population-based information and studies looking at principlesand approaches to diagnosis and treatment of diseases. GI Epidemiology brings together world authorities inmultiple disciplines for the very first time, to create one clearand comprehensive source. The bulk of the chapters are divided intotwo parts, covering methodological issues and the epidemiology ofspecific GI diseases. Each chapter begins with a list of keypoints, followed by a review written in a clear and simplestyle. The methodologic chapters cover evidence-based medicine,meta-analysis, systematic reviews, genetic and molecularepidemiology, clinical trials, questionnaire design, and healtheconomics. The disease-specific chapters note the current gaps inknowledge and suggest areas for further study. GI Epidemiology serves as both a useful refresher and areliable reference on the methods and techniques used inepidemiological studies for consultants and researchers ingastroenterology. It is also an invaluable tool for fellows/trainees ingastroenterology, candidates for recertification in the combineddisciplines of gastroenterology, pediatric gastroenterology andcolorectal surgery, and anyone completing MPH training.

Elastography, the science of creating noninvasive images of mechanical characteristics of tissues, has been rapidly evolving in recent years. The advantage of this technique resides in the ability to rapidly detect and quantify the changes in the stiffness of soft tissues resulting from specific pathological or physiological processes. Ultrasound elastography is nowadays applied especially on the liver and breast, but the technique has been increasingly used for other tissues including the thyroid, lymph nodes, spleen, pancreas, gastrointestinal tract, kidney, prostate, and the musculoskeletal and vascular systems. This book presents some of the applications of strain and shear-wave ultrasound elastography in hepatic, pancreatic, breast, and musculoskeletal conditions.

Consultations of Gastroenterology practitioners are frequently sought for many complex issues relating to acute and chronic liver disease. Many of the disease entities are uncommon and complicated in scope. Liver disease may occur in the setting of other chronic medical conditions and involve other organ systems, with recommendations for diagnostic strategies and therapeutic approaches somewhat challenging. Serious consequences are often the rule with misdiagnosed or inadequately treated liver disease. Dr. Flamm has provided a framework for approaching consultation for common liver-related problems for the gastroenterology practitioner. Articles are devoted to the following topics: Common Findings and Interpretation for the Clinician; Genetic Testing in Liver Disease: What to Order and When; Acute Liver Failure; Liver Disease in Oncology Patients; Primary Sclerosing Cholangitis: What the Gastroenterologist/Hepatologist Needs to Know; An Update on the Treatment and Follow up of Patients with PBC; Wilson’s Disease: Diagnosis, Treatment, and Follow Up; Follow Up of the Post-Liver Transplantation Patient: A Primer for the Practicing Gastroenterologist; Liver Disease in Patients on Total Parenteral Nutrition; Treatment Strategies in NAFLD: What’s Coming; Resistance Testing in Chronic HCV; and HCV genotype 3: Treatment Approach and Natural History.

Authored by the most prominent world experts in their areas of expertise, Variceal Hemorrhage serves as a very useful reference for gastroenterologists, GI surgeons, residents in internal medicine and physicians dealing with and interested in the different aspects of this severe medical emergency.

Alcohol abuse remains a significant problem world-wide. The most commonly affected organ remains the liver with a risk of alcoholic liver disease (ALD) which can range from asymptomatic to alcoholic hepatitis to alcoholic cirrhosis. In 2010, alcohol-attributable cirrhosis was responsible for 0.9% of all global deaths. Given the sheer magnitude of alcohol abuse and alcoholic liver disease, an update on this topic is pertinent and relevant. This issue will focus on a variety of topics including alcoholism, the pathogenesis of ALD, the spectrum of ALD, the pathology of ALD, and the long-term management of patients with ALD. Alcoholic hepatitis is a particular type of ALD with a high mortality. This issue will explore the syndrome of alcoholic hepatitis, its prognostic markers, and the available therapies. Because alcohol intake can influence so many other conditions of the liver (especially hepatitis C), articles in this issue will also explore the impact of alcohol abuse on other liver conditions. In addition, several other topics such as nutritional therapy for ALD, ALD and liver cancer, and ALD and infection risk will be explored. Also, even though it is quite controversial, we will also explore liver transplant as a therapy for alcoholic liver disease including alcoholic hepatitis.
