Summary
Cold urticaria, a common pediatric condition, is diagnosed via cold stimulation tests and clinical history. Cetirizine effectively treats cold urticaria with fewer side effects than older antihistamines.
Area of Science:
- Dermatology
- Allergy and Immunology
Context:
- Cold urticaria is a prevalent physical urticaria in children.
- It is triggered by exposure to cold stimuli like air, water, and food.
Purpose:
- To review characteristics of cold urticaria in pediatric patients.
- To evaluate diagnostic methods and treatment efficacy.
Summary:
- The study reviewed twelve pediatric patients with cold urticaria.
- Key findings include a mean age of 12 years 9 months, higher prevalence in females, and frequent atopy (67%).
- The cold stimulation test was positive in 92% of patients, while cryoglobulins and cold agglutinins were negative. Cetirizine showed 70% efficacy.
Impact:
- Highlights the diagnostic importance of the cold stimulation test and clinical history.
- Establishes cetirizine as an effective treatment option with a favorable side effect profile for pediatric cold urticaria.
