My 18-month-old son has had a diaper rash, with no other symptoms, within a few days of eating a poached egg on 3 separate occasions.
At his first well-child visit after a family move, an 8-year-old boy was noted to have bilateral erythematous plaques on the surfaces of his hands and feet. Mother reported that the condition had been present since he was 2 or 3 months old. Patient’s father and other male relatives on the paternal side (uncles, grandfather, great-grandfather) were similarly affected. No other associated symptoms, such as hyperhidrosis, reported. The child did not have a history of eczema, asthma, or food allergies; however, he did have a history of allergic rhinitis and occasional pruritus.
Allergy testing can aid the diagnosis of allergic disorders; however, it is not diagnostic. With skin testing, in particular, a positive result does not necessarily indicate clinical allergy, and a negative result does not always exclude clinical relevance.
Episodic right-sided facial flushing was noted in a 2-month-old girl born at full term via forceps-assisted vaginal delivery. The erythema appeared within minutes of latching onto her mother’s breast and resolved within 5 to 10 minutes after breastfeeding. The episodes of flushing had begun a week before the clinic visit; there were no collateral symptoms of anaphylaxis. Because food allergy was suspected, the mother had eliminated all dairy products from her diet.
A 5-month-old Asian boy was brought for evaluation of hair loss and a red, scaly rash on the scalp and body. The rash had not responded to hydrocortisone 2.5% ointment. There was a family history of asthma, food allergies, and allergic rhinitis. His mother had Hashimoto thyroiditis.
Twenty-two-month-old girl seen in the emergency department (ED) after several hours of abdominal pain associated with non-bloody, non-bilious emesis. Over past 2 months, has had 7 or 8 similar episodes of abdominal pain followed by emesis 1 to 2 hours later.
With the banning of peanut butter and jelly from some school cafeterias, peanut allergies have become a popular topic in the media and the public. Discussions often include references to an increasing prevalence of allergies, as well as to an earlier emergence of those allergies in children.

A 4-year-old girl presented with a sore throat, dysphagia, fever (temperature up to 40°C [104°F]), and a pruritic vesicular rash. On the first day of the illness, 4 days earlier, she was evaluated by her pediatrician who prescribed azithromycin for a presumed upper respiratory tract infection. About 2 days later, a papular rash developed on the abdomen and perioral skin; the fever had persisted, and the child's oral intake had decreased. The next day, the rash continued to spread, and the patient refused to take anything orally, including fluids. The mother thought that the rash was a hypersensitivity reaction to the antibiotic.
A 5-year-old boy with seizure disorder and developmental delay presented to our allergy and immunology clinic for a severe reaction that developed after he had received multiple vaccines. One month before our evaluation, the patient had been vaccinated against varicella, hepatitis A, and influenza at his pediatrician's office. Latex gloves were not used for vaccine administration.
