Psoriasis í Føroyum: Fyribils frásøgn

Abstract

In a provisional review an account is given of an examination of ^/g of the population of the Faroe Islands. Of 11.000 persons examined, 312 were found to be suffering from psoriasis (158 men, 154 women), the incidence of the disease being 2.84 %. The investigation covered all cases, specially including patients who would not normally seek medical advice. At the time of the examination 13 % had major eruptions, 76 % had minor eruptions, while 11 % were without symptoms. As psoriasis is almost untreated on the islands, it is possible to form an opinion as to the spontaneous course of the disease. Only 15.5 % showed constant major dissemination, 72.9 % showed either constant minor dissemination or a course with very few symptoms. 11.6 % had had constant major eruptions in early life, but on growing older have had only minor eruptions. 42 % of all patients have
gone through periods of major eruptions; 44.9 % have had periods quite free from symptoms. A few of the many comprehensive genealogical tables drawn up are shown. The most extensive of these includes 34 cases of psoriasis distributed over f ive generations. Psoriasis is seen to be inherited dominantly with failing manifestation. The manifestation probability is calculated to be about 40 %. A more detailed account of these investigations will be published later.
