[Pityriasis versicolor in Greece and its predisposition factors].
The age and seasonal incidence of 2610 patients with pityriasis versicolor in Greece were studied. Determination of the pH of Na and K ions of the sweat and the microbiol flora of the skin of pityriasis versicolor patients was undertaken. Besides these the effectiveness of a 1% selenium disulfid suspension was tested. The results indicate that the age groups of 20-29 and 30-30 years are mostly affected by the disease. A high incidence of the skin manifestation was noted during the summer and fall months. A difference of the pH of the sweat between pityriasis versicolor and healthy controls was observed, but no difference was found in the Na and K ions of the sweat among these two groups. Neither did the microbial flora from the skin lesions of patients and from corresponding sites of controls show any difference. The high relapse in this experiment indicates the relative ineffectiveness of selenium disulfid preparations when used as a 1% suspension in the treatment of pityriasis versicolor.
