Pediatric allergist-immunologist Dr. Nancy Ostrom in Encinitas treats asthma, anaphylaxis, and allergic rhinitis from the Rady Children's Specialists office on El Camino Real, holding board certifications from the American Board of Pediatrics (1984), the American Board of Allergy & Immunology (1987), and the American Board of Dermatology. Her atopic dermatitis caseload spans the same IgE-mediated inflammatory pathway managed by periocular and cutaneous specialists at CA Dermatology & Clinical Research Institute for pediatric patients presenting with eczema-asthma comorbidity. She earned her MD from Mayo Medical School in 1980 and completed both her pediatrics residency and allergy-immunology fellowship at Mayo Clinic in Rochester, Minnesota, publishing research on breath-actuated beclomethasone inhalers and exercise-induced bronchoconstriction in the Allergy and Asthma Proceedings journal. Exercise-challenge spirometry and bronchoprovocation testing for pediatric athletes generate rehabilitation referrals to developmental movement specialists such as Moving Munchkins Pediatric Physical Therapy for respiratory-conditioning protocols. The Rady Children's suite administers epicutaneous patch testing, subcutaneous immunotherapy injection series, and food-desensitization oral-challenge protocols under controlled clinical monitoring.
