[Oral 13-cis-retinoic acid therapy in adenoma sebaceum symmetricum and the most severe forms of acne and rosacea].

Twenty-one patients with severe acne (acne papulopustulosa, acne conglobata, acne cystica), six patients with severe rosacea (rosacea paulopustulosa, rosacea conglobata, rhinophyma), and three patients with tuberous sclerosis were treated with 13-cis-retinoic acid for 6-48 weeks. Most patients had been previously treated with dermabrasion, antibiotics or metronidazole. Dependent on the severeness of the pathological symptoms 13-cis-retinoic acid was administered at a dose of 0.2 to 0.5 mg/kg body weight and was then reduced every 4 weeks. We confirm the sebostatic and antiinflammatory effect of the 13-cis-retinoic acid and long-lasting remissions. Side effects had not been serious.

[Removal of tattoos by transplantation (author's transl)].

The replacement of tattoos by pedicle flaps demands a special ability and artistic skillfulness in order to avoid scars with the contours of the tattoo. The excision and the following cover with split-thickness-grafts should make the outlines of the tattoo invisible.

Biochemical and physiological parameters on the healthy skin surface of persons with candidal intertrigo and of persons with tinea cruris.

Biochemical and physiological tests were carried out on the skin surface of 20 patients with candidal intertrigo and 27 patients with tinea cruris. In all patients the test areas were free of efflorescences. The same tests were performed in 39 and 27 resectively healthy test persons of the same age and sex. The following striking findings came to light: 1. There was a significant decrease in the percentage amount of squalene in the skin surface lipids of the moniliasis group as compared with the control group. 2. There was a significant decrease in the reducing substances in the so called water solubles obtained with the phenol sulfuric acid method in the moniliasis group. The same results were obtained when only those moniliasis patients who were definitely not suffering from diabetes mellitus were taken into account. This is presumably a question of a reduction in the bound carbohydrates. 3. There were significantly more amino acids extractable from the skin surface of the tinea cruris patients than of the control persons. These results point to important predisposing factors for the susceptibility to candidal intertrigo and tinea cruris respectively.

Biochemical and physiological parameters on the healthy skin surface of patients with common warts.

Biochemical and physiological examinations were carried out on the healthy surface of the skin of 24 test persons who had had contracted common warts during the 2 years prior to examination and on a control group of 46 healthy persons of the same age and sex. The following significant results were obtained: (1) There was a significant reduction in the percentage amount of squalene in the lipids of the skin surface in the patients with common warts as compared with the healthy control persons. (2) The alkali neutralization time in the patients with common warts was significantly shortened as compared with the healthy control group. (3) The degree of moistening of the skin with water was significantly less in the patients with common warts than in the control persons. These results indicate important predisposing factors for common warts.
