family medicine residents. Over time it evolved into a fairly complete coverage of most of the outpatient issues seen in their training. In response to their urging, I set out on the journey to convert the manual into the manuscript for this book. The book is intended for primary care physicians, nurse practitioners, and physician assistants. It serves three purposes: (1) as a quick reference for primary care providers to use in the clinic when seeing patients, (2) as a textbook, and (3) as a study guide for Board examinations. It covers a great number of topics briefly to allow quick reading. To allow fast access, the chapters are arranged in alphabetical order beginning with Chapter 1: Allergy and ending with Chapter 27: Women's Health. Topics within chapters also are arranged in alphabetical order, again to allow quick access.
