In a survey for coronary risk factors 14 667 adult men and women answered a questionnaire on lifestyle, diet, and health, including whether they had psoriasis. The overali prevalence of psoriasis was 4-79% in men and 4-85% in women. The data showed an increasing incidence of psoriasis. The association with family history, lifestyle, diet, and health was explored by multiple regression analysis. The occurrence of psoriasis in first degree relatives contributed to more than 90% of the explained variance for both sexes. Of the other variables, only the positive association with rheumatoid arthritis was significant in both sexes.It is concluded that the examined environmental factors have only minor effects on the prevalence of psoriasis.

The effect of combined UVB-UVA treatment in a group of 23 patients with severe atopic eczema was compared to UVB therapy alone in 33 patients. Mean age and number of treatments were approximately the same in the two groups. With UVB-UVA treatment, 48% achieved complete remission and in another 48% good improvements were obtained as compared to 27 and 58%, respectively, in the group treated with UVB alone. A few failures were recorded in the UVB group. Some possible explanations for the better effect of the combined UVB-UVA treatment are given.
