Psoriasis í Foroyum.

SUMMARY
In a provisional review an account is given of an
examination of */3 of the population of the Faroe Islands.
Of 11.000 persons examined, 312 were found to be suffe-
ring 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 disse-
mination, 72.9 % showed either constant minor dissemina-
tion 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 five generations. Psori-
asis is seen to be inherited dominantly with failing manifes-
tation. The manifestation probability ~ís calculated to be
about 40 %.
A more detailed account of these investigations will be
published later.
