The first three editions of this invaluable handbook have been tremendously successful thanks to their accessibility and comprehensive cover of the medical specialties. Thousands of revisions and updates have been made and a new chapter has been added for the fourth edition. This best-selling book will give medical students doing their rotations absolute confidence on the ward, in the lecture theatre, and revising for exams. Now printed in three colours to make the information you need even easier to find when you really need it!
