This updated Fourth Edition continues to serve as a comprehensive introduction to family medicine. Written at the clerkship level, it groups chapters into three sections: Principles of Family Medicine, Promoting Health throughout Life, and Common Problems. New to this edition is a feature called Careers in Family Medicine, three additional chapters, and a division of respiratory tract infections expanded and split into upper and lower. Its user-friendly style makes the book a lasting companion tool for the approach to diagnosing and treating common problems. It comes with a CD-ROM that contains 100 USMLE-style questions with explanations to accompany the text.
