He took an over-the-counter combination of aspirin and caffeine, which seemed to help for about 60minutes, but the headache has returned full force. He has vomited twice-another characteristic typical of his migraineattacks

As many as half of patients who are evaluated for abdominal pain do not receive a precise diagnosis. And for about half of those who are given a diagnosis, the diagnosis is wrong. In this article, I will use actual cases (not "textbook" examples) to illustrate an approach to abdominal pain that begins with a careful differential diagnosis. I also offer some general guidelines for evaluating patients.

A systematic approach to the patient with resistant hypertension is both cost-effective and rewarding because the evaluation will probably reveal the cause. Initial considerations include lack of adherence, inappropriate treatment, drug-drug interactions, volume overload, and white-coat hypertension.

The physical examination was unrevealing, and the patient's personal and family medical histories were unremarkable.

Atropy of the paravertebral musculature--the "spine sign"--in this 64-year-old man offers clues to the genesis of the coronary artery disease for which he had undergone a coronary artery bypass graft (CABG) and to the cause of his severe post-CABG anterior chest pain.
