title: [Oral allergy syndrome among patients with birch pollinosis in Sapporo].
abstract: We evaluated the relationships between oral and pharyngeal hypersensitivity to fruits and vegetables (oral allergy syndrome) and birch pollinosis in 2003 in Sapporo. 1. Of 153 patients with birch pollinosis (seasonal nasal or ocular symptom and CAP positive [birch pollen CAP score 2 or more]), 65 patients (42%) have episode of oral allergy syndrome (OAS). And that rate in 2003 was higher than in 1992 and was equal to in 1998. 2. Among birch pollinosis patients, the higher the CAP score of birch pollen, the higher the prevalences of OAS were found to be. 3. Among birch pollinosis patients, female have OAS much more than male. 4. Among birch pollinosis patients in 1998, patients who visited to ENT clinic for medical consultation of birch pollinosis in March and April have OAS much more than patients who visited in May and June.
