Board Rounds | Medical School Headquarters | Prep For Usmle And Comlex

Session 17 Dr. Karen Shackelford from BoardVitals is joining me once again for another round of discussion. This week, we tackle a certain kind of pediatric illness. [01:11] Question of the Week: A 10-year-old male patient is evaluated for abdominal pain he has had for two days. He has a rash on his buttocks and thighs. It appeared about three days ago. He's also complaining of some pain in his ankles and knees. His past medical history is unremarkable. But he was seen in the clinic two weeks ago with symptoms of an upper respiratory infection. On physical exam, his abdomen has standard palpation. 01:42  He has multiple palpable purpuras on his buttocks and upper thighs. 01:50 His ankle is swollen and tender on the right. There's no warrant for eczema. His knee is tender. But otherwise, his exam was unremarkable. His laboratory study is showing a normal CBC. On urine 02:09, he has microhematuria. What is the most likely diagnosis? (A) IgA vasculitis (formerly Purpura) (B) Hemolytic uremic syndrome (C)
