对日本北海道白老町２７０２例学童进行耳鼻咽喉科体检。结果：①３５．５％患有鼻出血，１３．２％有鼻变态反应症状（打喷嚏、流清涕和鼻塞）；②变应原皮试阳性率３５．５％。③鼻出血组皮试阳性率４０．４％，鼻变态反应组鼻出血发病率为４４．６％，均明显高于对照组（Ｐ＜０．０１）。表明儿童鼻出血与鼻变态反应关系密切。 Otolaryngology examination was performed on 2702 schoolchildren in Balao-cho, Hokkaido, Japan. Results: ①35.5% had nosebleeds, 13.2% had nasal allergy symptoms (sneezing, runny nose and nasal obstruction); ② The allergen skin test positive rate was 35.5%. ③ The positive rate of skin test in nasal hemorrhage group was 40.4%, and the incidence rate of nosebleed in nasal allergy group was 44.6%, which were significantly higher than those in control group (P <0.01). Show that children with nasal hemorrhage and allergic rhinitis are closely related.
