APRENDIZAJE BASADO EN UN CASO CLINICO

CASE HISTORY

Medical History
In August 2002, an 8-year-old Asian female developed fatigue, fevers, and joint pain with swelling of her wrists and knees. Her family practice physician diagnosed acute rheumatic fever and started her on a course of aspirin and penicillin for four weeks. Her fevers improved, but she continued to have marked fatigue and developed swelling of her eyelids and feet.

Laboratory tests were obtained that showed a sedimentation rate of 120, and urinalysis with 2+ protein and 10-20 red blood cells/hpf. She was referred to a nephrologist who obtained an ANA titer of 1:1260. She was then referred to a pediatric rheumatologist.
