[The Berlin Model. A multicenter study of prednicarbate in various vehicles].

We report on the results of an openly conducted multicenter study concerning efficacy and tolerance of a new prednisolone derivative free from halogenic groups (prednicarbate 0.25%, Dermatop) prepared as a) emulsifiable greasy ointment without water, b) w/o emulsion (ointment), and c) o/w emulsion (cream). These preparations were therapeutically applied in eczema (allergic, seborrheic, microbic), psoriasis, and atopic dermatitis. The study was carried out in close team work between a clinic and 37 practicing dermatologists and included 383 patients. After 3 weeks therapy, 4% of the patients did not reveal any satisfying results; 16% showed medium outcome with some persisting symptoms; in 80% of the patients, we observed good to very good therapeutic results.

[Risks and health problems caused by the use of video terminals].

OBJECTIVE: To evaluate the association between video display terminal (VDT) use and health hazards, occupational risks, and psychosocial factors, in newspaper workers. MATERIALS AND METHODS: A cross-sectional study was conducted in 1998 in a representative sample (n = 68) drawn from a population of 218 VDT operators in Mexico City. Data were collected using a self-administered questionnaire. Data were confirmed by performing physical examinations. The research hypothesis was that both the current and cumulative use of VDT are associated with visual, musculoskeletal system, and skin illnesses, as well as with fatigue and mental or psychosomatic disorders. Occupational health hazards were assessed (visual problems, postural risks, sedentary work, computer mouse use, excessive heat, and overcrowding), as well as psychosocial factors related to work organization (psychological demands, work control, and social support). Prevalence ratios were adjusted for confounding variables like age, sex and schooling. RESULTS: Women were more likely than men to have upper extremity musculoskeletal disorders (MSD), dermatitis, and seborrheic eczema. VDT use was associated with neuro-visual fatigue, upper extremity MSD, dermatitis, and seborrheic eczema. Computer mouse use and postural risks were significantly associated with health problems. Psychosocial factors were mainly associated with mental problems, psychosomatic disorders, and fatigue. CONCLUSIONS: Intense use of video screens has been found to cause musculoskeletal disorders of the hand. The diversification of tasks and control of labor processes itself had a protective effect against psychosomatic disorders and pathological fatigue.

Altered capillary response to tape stripping in psoriasis and some other dermatoses: the petechial threshold test.

66 psoriatics, 34 normal adults, 10 normal juveniles, and smaller groups of patients afflicted either with seborrheic dermatitis-rosacea or atopic dermatitis were examined for the threshold of capillary petechia formation on clinically normal forearm skin in response to repeated tape stripping. A definitely lowered petechial threshold was found in psoriatics (mean of 9 vs. 19 tape strips) and also in persons with the seborrheic-rosacea complex. Normal juveniles and patients with atopic dermatitis had an increased threshold. The possible relation of these data are pointed out to recent findings of ultrastructural abnormalities of psoriatic papillary capillaries, and an altered capillary response is suggested as a sine qua non precondition for the development of psoriasis. The petechial threshold test is recommended as a simple adjunct diagnostic tool.
