Abstract

|
The author studied the relationship between several dermatoses and the climate by summation of the onset of the cases of the each dermatoses according to every month and monthly mean value of the climate, particularly air temperature, relative humidity and discomfort index during 4 years from 1962 to 1965 in Taegu area.
The dermatoses included for study were eczema-dermatitis groups, superficial dermatomycoses pyodermas, erythema multiforme, erythema nodosum, urticaria, insect bite, strophulus infantum, pruritus, pityriasis rosea, tuberculosis cutis, pityriasis simplex, miliaria, frost bite, psoriasis vulgaris syphilis, leprosy, scabies sicca, and viral skin diseases and following results were obtained.
1. According to the 4 seasons, various changes were noted, the prevalence rate of the eczema-dermatit groups, insect bite leprosy, strophulus infantum, erythema nodosum, erythema multiforme were higher In spring, among these, eczema-dermatitis groups, strophulus infantum and erythema multiforme were increased in summer too. Superficial dermatomycoses, pyodermas, urticaria, viral skin diseases, syphilis, tuberculosis cutis and miliaria were more prevalent in summer, while pityriasis simplex, frost bite, and pruritus were´ more numerous in winter.
2. Eczema-dermatitis groups were mostly prevalent in April, May and July. Among these, contact dermatitis were higher in spring and seborrheic dermatitis and neurodermatitis were increased in July. June and July respectively. While infantile eczema and atopic dermatitis were prevalent in winter, and nummular eczema were increased during the winter and spring.
3. Superficial dermatomycoses, particularly tinea pedis et manus and tinea versicolor were mostly increased in July, therefore, it seems these skin diseases were much affected by the air temperature and relative humidity.
4. Pyodermas were also highest in July and August and it would appear that these conditions were also affected by the air temperature and relative humidity.
5. Erythema multiforme were increased during March and April and July to August.
6. Erythema nodosum were highly prevalent in March and April.
7. Uryicaria were highest in July and August.
8. Insect bite were highest in April and Mav.
9. Strophulus infatum occurred mostly from April to July.
10. Pruritus, pityriasis rosea, and pityriasis simplex were much less in summer and more numerous in the other 3 seasons.
11. Miliaria occurred mostly in summer, especially highest in July, so this condition appears to be affected both by air temperature and relative humidity.
12. Frost bite was prevalent from November to February, the highest incidence was recorded in January. 13. Leprosy showed high incidence in spring.
14. Psoriasis vulgaris, syphilis, scabies sicca, and viral skin diseases appeared to be unaffected by the seasons or climatic changes.
15. It is difficult to ascertain which of these air temperature, relative humidity and discomfort index affects the varying skin diseases, they also could be affected by air pressure, wind, rain, snow and evaporation.
