Prepared by residents and attending physicians at Massachusetts General Hospital, this pocket-sized looseleaf is one of the best-selling references for medical students, interns, and residents on the wards and candidates reviewing for internal medicine board exams. In bulleted lists, tables, and algorithms, Pocket Medicine provides key clinical information about common problems in cardiology, pulmonology, gastroenterology, nephrology, hematology-oncology, infectious diseases, endocrinology, rheumatology, and neurology. The six-ring binder resembles the familiar "pocket brain" notebook that most students and interns carry and allows users to add notes. This Third Edition is fully updated, has tabs to help readers locate organ systems, and has more cross-referencing in the index. It also has pockets in the front and the back of the book to accommodate the reader's own notes.
