Circumscribed erythematous lesions developed on the back and abdomen of this 19-month-old boy. The rash was mildly pruritic. The parents gave the child 1 dose of diphenhydramine, and the rash resolved after an hour. About 12 hours later, new lesions developed on the face, neck, and upper back. The child was given the same treatment and the symptoms resolved. The following morning, widespread lesions were noted on the child's face, neck, trunk, and extremities.

An 18-year-old woman with a history of allergic rhinitis and moderate persistent asthma presented with right-sided nasal congestion of 6 months’ duration. Her symptoms persisted despite her usual allergy medications, allergen immunotherapy, and 2 courses of antibiotics. A sinus CT scan showed complete opacification of the right maxillary sinus with increased attenuation of the mucin. Allergic fungal rhinosinusitis was suspected, and an otolaryngologist was contacted.

To allay children's fears about immunizations or allergy shots, keep a pocket-sized, battery-operated radio in the office.

For my patients who use nasal spray, I advise them to use the right hand to spray into the left nostril and the left hand to spray into the right nostril.

Advise patients who are receiving continuous positive airway pressure (CPAP) therapy and who use a corticosteroid nasal spray for allergies to spray in the morning rather than at bedtime. If the spray is used in the evening, CPAP may dry it out, making it less effective.

Children sometimes have difficulty using nasal sprays for allergies.

To prevent epistaxis or damage to the septum from the use of a corticosteroid nasal spray, advise patients to cross their arms and spray with the hand contralateral to the target nostril.
