Titles in the Pocket Tutor series give practical guidance on subjects that medical students and foundation doctors need help with ''on the go''. Their highly affordable price represents great value for those rotating through modular courses or working on attachment. Topics reflect information needs stemming from today's integrated undergraduate & foundation courses: * Common investigations (ECG, Chest X-Ray, etc) * Clinical skills (procedures, patient examination, etc) * Important and/or complex specialties in which students receive comparatively little dedicated training (psychiatry, renal medicine) Key Points * Highly affordable price and convenient pocket size format - fits in back pocket! * Logical, sequential content: relevant basic science; understanding normal results and the building blocks of abnormal results; then clinical disorders * Clinical disorders illustrated by a full page chest radiograph with brief accompanying text on facing page that clearly identifies the defining features of the X-Ray (in other words, what is it that makes this pneumothorax?)
