Your child may be allergic to your holiday pumpkin pie, according to allergists at the annual scientific meeting of the American College of Allergy, Asthma and Immunology (ACAAI) in Phoenix. Hot topics discussed in pediatric allergies include pumpkin and caterpillar allergies, and outgrowing childhood allergies.
Although pumpkin is not a food usually associated with allergic reactions, the Annals of Allergy, Asthma and Immunology, the scientific journal of the ACAAI, reported a case study of an 8-year-old boy with known asthma and food allergies who became sick after carving a pumpkin. His symptoms included itchy eyes, sneezing, eyelid swelling and chest tightness. Allergists say these symptoms can occur after carving or eating pumpkin.
"An allergic reaction to pumpkin can occur even if your child has had no prior reactions," said pediatric allergist John Kelso, MD, of the ACAAI Pediatrics and Literature Review Committees.
And although your little one may want to catch a caterpillar and see it become a butterfly, case studies show caterpillars can also cause allergic reactions in some children. Direct contact with caterpillars or breathing airborne caterpillar hairs can cause hives or respiratory symptoms. Extensive or prolonged exposure can cause life-threatening anaphylaxis.
"These may be rare allergies, but it may also be that we are just becoming more aware of them," said Dr. Kelso.
Pediatric allergists also presented new ideas on childhood allergies and asthma topics including:
