[Therapy of aging skin]. / Therapie der Altershaut.

The process of involution of aging skin is essentially caused by functional changes progressing as a consequence of the chronic influence of exogenous noxae. Reasonably, prophylaxis should avoid actinic damages, and skin care should be adapted to the changes due to age, which means providing a substitute for cutaneous lipids and stabilizing the hydration of the horny layer. Placebo-controlled studies proved that topical treatment with 0.05% tretinoin can result in the regression of degenerative and precancerous changes of the senile skin caused by chronic exposure to UVB. However, long-term results remain to be seen.

[Diagnosis and therapy of Raynaud's phenomenon in occupationally-induced vibration trauma]. / Zur Diagnostik und Therapie des Raynaud-Phänomens bei beruflich bedingtem Vibrationstrauma.

Raynaud's phenomenon often represents an early symptom of collagen diseases as well as of occlusive vascular disease; it can as well be due to vibration trauma following development of mechanical lesion of the acral capillary system. A rare case of professionally acquired vibration trauma in a miner who developed vasospastic ischaemia after 20 years subterranean work is reported. Non-invasive blood-flow measurements such as thermic relaxation time, transcutaneous O2-pressure, and laser-doppler perfusion rate, represent suitable means of diagnosis and observation of the course of the disease. Combination therapy including both primary inhibition of platelet aggregation as well as improvement of rheological properties has proved to be superior to other treatment plans.
