Two months ago, the patient underwent a diagnostic left heart catheterization without acute intervention. The patient’s past history was otherwise uneventful. He exercises regularly, does not smoke and drinks 5-6 glasses of wine a week.
Physical examination reveals a patient who appears mildly ill. Temperature is 102° F, Blood Pressure is 132/80 in the right arm, Pulse is 96 and regular, and Respirations 16/minute.
Examination of the skin reveals a very tender nodule on the flexor surface of distal interphalangeal (DIP) joint of the 3rd finger and cyanotic changes at the tips of three fingers (Fig 1). The lesion is papular and is very tender. There are a moderate number of petechiae along the inner surface of the conjunctiva of the lower lid of the right eye (Fig 2).

About Bedside Diagnostic Challenge:
Except for Hospitalists, Emergency Medicine physicians, and Interventional Cardiologists, most internists will spend the bulk of their professional time with patients in an office setting.
Here is where finely tuned clinical skills are most important in leading to accurate diagnoses, fewer complications resulting from unnecessary tests and procedures, and lower costs. Med Challenger Bedside Diagnostic Challenge reinforces the value of these clinical skills and tests users on their knowledge of them.
Bedside Diagnostic Challenge questions are issued periodically every month as a free content benefit of Med-Challenger.
