Book excerpt: Prepared by residents and attending physicians at Massachusetts General Hospital for Children, Pocket Pediatrics follows the style of Pocket Medicine, one of the best-selling references for medical students, interns, and residents. This pocket-sized looseleaf can be used on the wards and by candidates reviewing for pediatric board exams. In bulleted lists, tables, and algorithms, Pocket Pediatrics provides key clinical information about common pediatric problems in cardiology, pulmonology, gastroenterology, nephrology, hematology-oncology, infectious diseases, endocrinology, rheumatology, and neurology as well as on the well patient and the patient in the ICU. The six-ring binder resembles the familiar "pocket brain" notebook that most students and interns carry and allows users to add notes.
