Antikeratin 14 monoclonal antibody staining in psoriasis and seborrhoeic keratosis: immunofluorescence and two colour FACS studies.

A monoclonal antibody (ES3A) was raised against a mouse graft-versus-host reaction (GVHR) model. This antibody was against basal cell cytoplasm and reacted with an acidic (pI 6.2) 50 kDa keratin of human epidermis. However, ES3A reacted with several lower layers of epidermal cells in psoriasis and seborrhoeic keratosis. Acanthotic seborrhoeic keratosis showed varying patterns even in a single lesion. If combined with FACS analysis, ES3A-positive cells could be quantified. Normal skin showed 28%, while psoriasis and seborrhoeic keratosis showed 44% and 51%, respectively. ES3A-positive compartments of the acanthotic type of seborrhoeic keratosis were larger than those of the hyperkeratotic type. ES3A may be suitable for quantification of germinative or proliferative cells.

Glutathione in human epidermal tumors. Basal and squamous cell epithelioma, verruca seborrhoeica.

Methods for the determination of glutathione in small epidermal and tumor fragments are compared. The best results were obtained by an enzymatic cycling technique. The total glutathione concentrations in basal cell epithelioma, squamous cell epithelioma, and verruca seborrhoeica were 2.08, 1.81, and 1.87 mg/g dry weight, respectively. In normal epidermis adjacent to the basal cell epitheliomas the concentration was 1.27 mg/g dry weight.

Treatment of gram-negative folliculitis with isotretinoin.

The clinical and bacteriological findings are reported in 13 patients with gram-negative folliculitis before, during, and after treatment with isotretinoin (13-cis-retinoic acid). Patients were treated for 14-36 weeks with a daily dose of 0.5-1.5 mg isotretinoin/kg body weight. Inflammatory lesions were counted before and during weeks 2, 4, 8, 12, 16, 20, 24, 28, and 30 of therapy and again up to 172 weeks after cessation of treatment. In all patients there was an impressive improvement in clinical symptoms, especially a decrease in seborrhea and inflammatory lesions. Simultaneously, the gram-negative bacteria disappeared from the facial skin. Full clinical bacteriological remission was achieved in 9 patients within a period of up to 43 months, with minor recurrences of the disease in the remaining 4 patients.

13-cis-retinoic acid in conglobate acne. A follow-up study of 14 trial centers.

A follow-up was done on the patients of the German multicenter study with severe conglobate acne who had been treated with different dosages of 13-cis-retinoic acid. Eighty-seven patients were monitored from 12 to 21 months. Optimal long-term therapeutic effects were obtained with an initial dose of 1.0 mg/kg body weight, for 3 months, followed by another 3-month-treatment period with 0.2 mg/kg body weight. Six months after the termination of therapy 96% of the patients were still in remission and 81% after 12 months. Comparative figures for the administration of doses were 84% as opposed to 47% (0.5----0.2 mg/kg body wt.) and 74% as opposed to 37% (0.2----0.2 mg/kg body wt.), respectively. It is suggested from the present data that a high initial dosage of 13-cis-retinoic acid be chosen in order to obtain optimal long-term therapeutic effects. Transiently elevated lipid levels as well as other tolerable side effects return to normal within 3 months at the latest after discontinuation of treatment.
