Abstract
To know the character of pollinosis in childhood, two comparative studies were performed. One is a study on the difference bewteen 42 pollinosis-children aged under 15 years and the first control group consisting of the adult patients with pollinosis, and the other study is concerned with the difference of clinical pictures between the above mentioned pollinosis-children and the second control group consisting of the children with perennial nasal allergy. From these studies, the following results were obtained:
1) Sexual ratio in the children was respectively 2.5: 1 in the pollinosis and 3: 1 in the perennial nasal allergy, which was significantly differed from that of the adult patients (P<0.001).
2) The case accompanied by perennial nasal allergy was found in 60% of the pollinosis children, which was significantly higher than 30% of the adult patients (P<0.01).
3) As a rule, the severity of children's nasal symptoms was less than that of the adult patients (P<0.001).
4) Itchy eyes was noticed more frequently in the pollinosis children as compared with the children of perennial nasal allergy (P<0.05).
5) There was the tendency that the initiatory age of suffering from pollinosis was elder that of the perennial nasal allergy.
6) As to the variety of sensitizer (pollen) and the rate sensitized by double antigens, no difference between the children and the adults was found.
7) The difference of family and past history concerned in “atopy” were not found between the pollinosis children and the children of perennial nasal allergy.
