Abstract

The authors report the results of a statistical study of 1919 cases with nasal allergy treated at the Wakayama University Hospital during the 10 years from 1969 to 1968.
Combined cases of nasal allergy and bronchitis were seen in 23. 8%, nasal allergy and skin lesions in 6. 0% and the remaining 72. 7% were nasal allergy without associated diseases.
Forty-five point seven percent of nasal allergy cases were found to have developed before 15 years of age and 75. 8% of the cases which were associated with asthma were also found before 15 years of age.
Eosinophilia was seen in 34. 5%, eosinophilic cells in the nasal smear in 71%, both of which showed a high incidence among young patients. The incidence of positive skin test for house dusts and alternalia were greater among young patients, while that of pollinosis was high in the thirties.
