Each chapter is headed by a symptom or condition, and the reader is then led quickly into clear and up-to-date advice on managing them, without expanding into aetiology. I was particu- larly pleased to see useful advice on diffi cult-to-manage symptoms, such as nausea and vomiting and thoracic pain, and the inclusion of nutritional treatment. The chapter on HIV disease will be especially useful to the average gastroenterologist or general physician faced with the myriad of potential complications of this disease and side effects of treatment. The authors are to be congratulated. I predict this will be a handy refer- ence book (in the hand or on a screen), for all grades of doctors faced with these common problems. Sir Richard Thompson President Royal College of Physicians London, UK January 2013 This page intentionally left blank vii Preface This book focuses on managing the sick gastroenterology and hepatol- ogy patient, providing a point of rapid reference for use at the bedside. We make no apologies for covering a wide range of problems, as what may seem mundane to the visiting physician can be an emergency for the patient. Throughout, we have focused on giving practical advice, try- ing to answer the sorts of questions we have both faced over the years, as well as addressing emergency topics that are minimally covered or absent in other texts. This book provides contemporary guidance for doctors training in gastroenterology and hepatology, their seniors, and other team members responsible for the assessment and care of the acute medical patient. It complements the Oxford Handbook of Gastroenterology and Hepatology that one of us co-authored. We are grateful to its other co-authors Stuart Bloom and George Webster for their advice and friend- ship over many years. On a personal note, we would also like to thank the following experts, who have peer-reviewed many of the chapters or provided some of the images: Mike Anderson, Martyn Caplin, Tom Doherty, Matthew Foxton, Brian Gazzard CBE, John Karani, Aamir Khan, Nas Khan, Rob Miller, Iain Murray–Lyon, David Nott OBE, James O’Beirne, Alastair O’Brien, David Patch, and Stephen Wright. We are particularly grateful to Kevin Moore, editor of the Oxford Handbook of Acute Medicine, who was instrumental in this book’s early stages and who has contributed some content. We also thank our families for their support, and OUP for its patience. Finally, we thank you, the reader, without whom the written word has no purpose. We invite you to contact us with any suggestions to improve the text.
