The revised, updated Fifth Edition of this pocket book is a handy reference to consult when making bedside interpretations of clinical data. Remarkably complete for its small size, the book lists nearly 200 symptoms, physical signs, laboratory test results, and radiologic findings and their differential diagnoses.

This edition has a new, more user-friendly two-color design, tabs indicating sections, and shortened lists of the most common diagnoses. An expanded section on HIV infection covers new manifestations, including immune reconstitution syndrome. The infectious disease chapter has been revised to reflect its increasing importance in clinical medicine, the emergence of multi-drug resistant bacteria, and the threat of bioterrorism.
