The physical examination revealsmultiple small, nonblanching papules with associatedpurpura most pronounced on the buttocks, below theknees, and around the ankles. When the child’s ankle isgrabbed, he winces. ‘‘He’s been hobbling around thehouse. I think he twisted his ankle at soccer practice,’’themother says. A complete blood cell count and completemetabolic panel are normal. However, the urine shows atrace hematuria without proteinuria.
1. If you begin a course of prednisone 1 mg/kg/day for
2 weeks, which of the child’s symptoms is most likelyto respond?a. Insomniab. Rashc. Gastrointestinal complaintsd. Hematuriae. Anal pruritis2. When discussing the finding of hematuria in thiscondition with the mother, which of the following ismost accurate?a. Most children with this condition have blood in
their urineb. The hematuria is harmless and should not be
considered relevantc. Her son is most likely going to require dialysis at
some pointd. Hematuria is common, but it rarely progresses to
more serious renal diseasee. Prednisone will lower the risk of her son’s hema-
turia, progressing to end stage renal disease
A 34-year-old woman with an 8-month history of ex-tremely pruritic lesions on her arms and legs presents toyour office. She was diagnosed with ‘‘eczema’’ by herprimary care physician, but despite the use of multiplesteroid creams, there has been little improvement in hersymptoms. She states that she is so uncomfortable that shefinds it difficult to concentrate at work and she wakes up atnight scratching. The physical examination reveals multi-ple erythematous, excoriated papules on the elbows andknees and the small of her back and buttocks. Her ante-cubital and popliteal fossae are spared of lesions, as are herfinger webs, umbilicus, and wrists. On direct questioning,she states that there are frequently ‘‘water blisters’’ in thearea of the itching.
3. What is the next step in confirming the diagnosis in
this patient?a. Obtain a skin biopsy specimen to include directimmunofluorescence of immunoglobulin A anti-bodies to epidermal transglutaminase
b. Obtain a biopsy specimen of the small bowelc. Scraping of the lesion for microscopic evaluationd. An enzyme-linked immunosorbent assay for
antiepidermal transglutaminase in the serume. Begin a gluten-free diet

4. What should be the initial step in treatment of thepatient’s disease?a. Topical dapsone and initiation of a gluten-free dietb. Oral dapsone and initiation of gluten-free dietc. Sulfasalazined. Potent topical steroidse. PUVA
5. In counseling the patient regarding her disease, whichof the following is accurate?a. A strict gluten-free diet will most likely result in
resolution of her lesions within 6 weeksb. She is at a significantly increased risk for
non-Hodgkin lymphomac. A biopsy specimen of the small bowel would most
likely reveal villous atrophyd. Treatment with dapsone generally takes 6 weeks
to demonstrate an improvement in the prurituse. Other than celiac disease, there are no known
associated conditions from which her diagnosisplaces her at increased risk
