[Air pollution and health - counselling options for physicians]. / Luftverschmutzung und Gesundheit - Optionen in der klinischen Beratung.

While air quality is usually an environmental condition patients can little do about, there are a few options and decisions that modify the personal exposure and risk. Location - in particular the residence - time and activity are the key determinants of personal exposure. Traffic-related primary pollutants such as ultrafine particles or diesel soot are highly concentrated along busy roads but reach urban background concentrations already some 100 - 200 meters off. Morbidity and mortality follow this spatial pattern, which is usually attributed to these pollutants. Depending on ventilation systems, indoor exposure can be substantially lower. Studies done in China confirm that the use of face masks in extremely polluted cities can reduce exposure, resulting in lower inflammatory and cardiovascular responses. A diet rich in antioxidants appears to also reduce some of the oxidative and inflammatory effects of air pollution and treatments such as leucotrien receptor antagonists or statins pay interfere with some of the adverse effects of pollution. However, the benefits, if any, are unlikely to be large. A quantitative comparison of the various pollution related health effects - namely from smoking, passive smoking and air pollution - reveal a typical paradox to be well understood: the individual risks related to air pollution and that one may reduce through personal decisions are rather small. However, given the large number of people exposed (i. e. in essence the entire population), the overall air pollution related health burden is rather substantial. This underscores that sustained clean air policies are indeed the most important and efficient solution to reduce the air pollution related health effects.

Skin findings related to chronic usage of anti-epileptic drugs.

OBJECTIVE: Chronic type skin reactions are defined as unwanted effects of drugs. As there are more benign conditions, skin findings related to chronic usage of anti-epileptic drugs (AEDs) have not been studied previously. In this study, we investigate the skin findings associated with the chronic usage of AEDs. METHODS: The study was conducted in the Post, Telephone and Telegraph Training and Research Hospital between May 2002 and January 2003 during a 6-month work period. Skin lesions were first assessed individually, and then their correlations with AEDs were examined. Skin findings were then divided into skin disease groups to evaluate statistical significance. The prevalence of skin findings occurring in 62 epileptics was compared with that of an age-matched group of 33 non-epileptics. RESULTS: The rate of skin findings defined in the workgroup was 85.5%, while it was 84.8% in the control group. The most common skin findings were acneiform eruptions for both groups. There was no significant differences between the work and study group as for skin findings (p>0.05). Alopecia was the only skin condition related to AED usage and it was seen in 4 patients (6.5%) using valproate (p<0.05). None of the 11 patients with infectious skin findings were using valproate, and that was the only significant relationship between antiepileptic drugs and skin diseases (p=0.015). CONCLUSION: The inflammatory skin diseases were the most commonly seen problem in both patients and controls. The alopecia ratio with valproate usage in our patient group was similar to literature reports.
