Common variable hypogammaglobulinemia presenting as nontypable Haemophilus influenzae septic arthritis in an adult.

Haemophilus influenzae is a rare cause of septic arthritis in adults. We describe a case of septic arthritis with nontypable Haemophilus influenzae presenting as the first invasive infection leading to a diagnosis of common variable hypogammaglobulinemia. Although nontypable strains have been shown to cause serious infections in adults, they are a rare cause of septic arthritis.

Evaluation of system providing feedback to students on videotaped patient encounters.

A technique in which feedback is provided on videotaped performances to teach interview and examination skills in a pediatric clerkship was evaluated with a single-blind, controlled study. At the beginning of the pediatric ambulatory rotation, each of 105 third-year medical students received verbal and written instruction in conducting pediatric patient interviews and examinations. Then an encounter between each student and a patient was videotaped using a stationary camera mounted in an examination room.
