who were instrumental in helping create this textbook Many of my colleagues in Orlando helped with finding interesting cases, particularly Dr Mark Clark Several emergency medicine residents served as primary reviewers for much of the material in this endeavor, particularly Dr Clifford Denney My son, Nathan O’Brien, who recently completed his medical school training at Vanderbilt University and has begun his post-graduate training in emergency medicine, was perhaps the most detailed reviewer of all The formal reviewers, Dr John Younger and Dr Peter Thomas, added many specific suggestions for improving the case discussions Peter Beynon was a great help in word crafting the discussions to make them more interesting and succinct Paul Bennett was instrumental in formatting the cases into an attractive casebook My commissioning editor at Manson Publishing, Jill Northcott, was ever supportive in helping me accomplish this complicated task Last, but most importantly, I wish to thank my wonderful wife Rhonda, who served as primary typist, organizer, and encourager Without her tremendous help it is unlikely this would have ever been completed Copyright © 2013 Manson Publishing Ltd

care is frequently both challenging and exhilarating An ever-expanding knowledge base is necessary, coupled with clinical judgement and the ability to process often quite complex information Much can be gained from experience in the emergency medicine clinical arena, and this selfassessment book attempts to assist in that endeavor through a case-based approach Using a series of common as well as more unusual presentations, this text attempts to inform and refresh the reader across the entire spectrum of adult emergency medicine Although pediatrics is not covered in these pages, a similar case book specific to children is available through this publisher Medical trainees and qualified practitioners working not only in general emergency medicine, but also in primary care and other specialties, may use these cases to test and refine their abilities to care for a wide variety of patients This book employs questions to stimulate the reader to think about the evaluation and management of each patient, using a combination of photographs, radiographs, electrocardiograms, and other data Discussions ensue, which should highlight various aspects of the case including differential diagnoses, management issues, and subtle insights to provide optimal care and prevent complications Please enjoy the ride as you assimilate much of what is necessary to practice the art of emergency medicine Note that regional variations in the provision of emergency care exist The reader should feel free to add to the learning experience by exploring the references attached to each case In addition, specific practice guidelines should be sought from reliable local resources and societies Clearly, a variety of management techniques can be thoughtfully applied to many clinical situations, and this book can only provide some evidence-based approaches John O’Brien Classification of cases Cardiology 1, 16, 45, 57, 73, 75, 91, 94, 102, 108, 112, 114, 120, 128, 131, 146, 147,
