A 14-month-old boy is brought to his physician's office because of a diaper rash. Three weeks earlier, he was seen in the emergency department for a beefy-red, plaquelike perineal rash with multiple erythematous papules. The rash did not improve with over-the-counter topical creams and topical nystatin alone, but responded briefly to a regimen of oral cephalexin (Keflex) and fluconazole (Diflucan) with topical nystatin cream. The patient subsequently developed white bumps and blisters in the diaper area and a fever of 105°F (40.5°C). His mother reported that she had recently developed lesions on her lip that crusted over and resolved within a few days.
Physical examination revealed multiple vesicles with discharge in the groin and perineum. There was significant erythema in the groin, perineum, and scrotal area with multiple ruptured and intact vesicles that were 0.3 × 0.3 cm in size (Figures 1 and 2). Ulcerated skin was observed in the gluteal cleft and intertriginous areas. The infant was admitted to the hospital for treatment.
Laboratory testing showed an elevated C-reactive protein level of 2.08 mg per L (19.81 nmol per L) and a white blood cell count of 23,000 mm3 (23 × 109 per L). Vesicle fluid was collected for bacterial and viral testing.
Based on the patient's history and physical examination findings, which of the following treatment options is most appropriate?
A. Acyclovir (Zovirax).
C. Mupirocin (Bactroban).
E. Zinc oxide cream.
