Multiple trichoepithelioma is an uncommon skin disease with autosomal dominant transmission. It is characterized by multiple, benign facial skin lesions. These lesions constitute a formidable cosmetic and therapeutic problem. Treatment modalities are numerous and varied. In a few rare cases, confluence of the lesions may result in occlusion of the auditory canal, with consequent loss of hearing. In such cases the treatment of choice should be excision and split-thickness skin grafting.

Smoking behavior and attitude toward smoking regulations and passive smoking in the workplace. A study among 974 employees in the German metal industry.

BACKGROUND: Smoking regulations at the workplace have been found to be acceptable and effective in many studies conducted in the United States. There is limited knowledge, however, on acceptance and effects of smoking regulations in European countries, particularly among blue collar employees. METHODS: We conducted a survey on smoking behaviour and attitude toward smoking regulations and passive smoking in a South German metal company. A self-administered questionnaire was mailed to 1,500 predominantly blue collar employees of whom 974 participated in the study (response rate 64.9%). RESULTS: About 30% of the employees were not allowed to smoke at their immediate work area. Among them, about 95% of both smokers and nonsmokers agreed with this smoking policy. More than 60% of nonsmoking blue collar workers were bothered by passive smoking at work whether or not smoking was allowed at their immediate work area. In contrast, the proportion of nonsmoking white collar employees who were bothered by passive smoking varied from 52% if smoking was allowed at their immediate work area to 18% if smoking was not allowed. Prevalence of active smoking and average amount of smoking among active smokers were considerably lower among employees who were not allowed to smoke at work than among other employees. These differences were partly due to confounding by occupation, however, which was strongly related to both smoking habits and smoking policy. CONCLUSIONS: Our results, which confirm and extend previous findings, give further support to the acceptability and potential effectiveness of smoking regulations at the workplace. Particular efforts should be devoted to limit both active and passive smoking among blue collar employees.

Distribution, determinants, and prognostic value of gamma-glutamyltransferase for all-cause mortality in a cohort of construction workers from southern Germany.

BACKGROUND: Serum gamma-glutamyltransferase (GGT) is commonly measured as a marker of hepatobiliary disorders in clinical practice, but little is known about its distribution and prognostic value for all-cause mortality. METHODS: Distribution and determinants of serum GGT levels were assessed among 8,043 construction workers ages 25-64 who underwent occupational health examinations in six centers in Southern Germany from 1986 to 1988. Study participants were followed for all-cause mortality until 1994. RESULTS: Serum GGT levels were considerably higher in this cohort than among male employees examined in a national survey conducted during the same period. The factors most strongly related to serum GGT were self-reported alcohol consumption, body mass index, diabetes, and hypertension, but relations of GGT levels were also found with nationality, occupation, and smoking. There was a strong dose-response relation between serum GGT levels and all-cause mortality (P value for trend < 0.001). Compared with men with GGT levels below 15 U/liter (measured at 25 degrees C), relative risks (95% CI) were 1.46 (0.86-2.49), 1.78 (1.08-2.94), 2.09 (1.26-3.45), and 3.44 (2.20-5.38) for men with GGT levels of 15-19, 20-29, 30-49, and > or = 50 U/liter, respectively. This relation was reduced but not eliminated by control for body mass index, diabetes, hypertension, alcohol consumption, and other covariates in multivariable analysis. CONCLUSION: Serum GGT is a strong risk indicator of all-cause mortality.
