Abstract
A retrospective study was performed in 113 patients with allergic rhinitis who visited the out-patient clinic in the Department of Otorhinolaryngology, Shuto General Hospital during 1 year from January to December 1988.
Although our hospital is located in a rural city where was pollution-free and good environmental area, many patients with allergic rhinitis visited us. High positive reactions of allergic skin tests were Japanese ceder, house dust, ragweed and orchard grass. About 60% of patients visited first in February, March and April when was the season of Japanese ceder pollen scattering. From the above, it was considered that most of patients with allergic rhinitis who visited our hospital are Japanese ceder pollinosis.
