In-Flight Ultraviolet Radiation on Commercial Airplanes.

Introduction: Epidemiological studies suggest that pilots and cabin crew have higher incidences and mortality rates of cutaneous malignant melanoma than those of the general population. Exposure to UV radiation is one of the main risk factors for this type of cancer. The aim of this study was to evaluate the level of UV radiation in an airliner in flight.

Immunogenicity and safety of a new inactivated hepatitis A vaccine: a clinical trial with comparison of administration route.

A bicentre, controlled, randomized, open trial was carried out in order to compare the immunogenicity and the reactogenicity of PASTEUR MERIEUX Sérums et Vaccins inactivated Hepatitis A Vaccine on adults, when used with different routes of administration [intramuscular (i.m.), subcutaneous (s.

Seroprevalence of hepatitis A virus infection among sewage workers in the Parisian area, France.

Sewers are an ideal environment to be occupationally exposed to viral hepatitis A (HAV) infection, because of high frequency and ability of the virus to remain viable for prolonged periods in sewage. However, data on the occupational risk of HAV infection among sewage workers is not well documented. In a cross sectional study comparing sewage workers (n = 155) to those not occupationally exposed to it (n = 70), we found a non significant increase in HAV seropositivity among sewage workers of 12.

[Influence of the risk factors of atherosclerosis on the onset of early peri-operative complications in peripheral arterial surgery].

The influence of classical atherosclerosis risk factors (male sex, smoking, hypercholesterolemia, diabetes, overweight and hypertension on peri-hospital mortality and morbidity were studied in 83 patients (68 men and 15 women) aged 63 +/- 13 years and undergoing peripheral arterial surgery. None of these factors was statistically correlated with peri-operative complications with the exception of hypertension but the correlation was slight (0.5 less than p less than 0.

Assessment by dipyridamole-thallium-201 myocardial scintigraphy of coronary risk before peripheral vascular surgery.

From October 1983 to January 1985, 46 patients (38 men and 8 women; average age, 60 years; range, 37 to 83 years) underwent peripheral vascular surgery of either the internal carotid artery or the arteries of the lower limbs. Each patient had a thorough clinical examination, an ECG, and a dipyridamole-thallium-201 myocardial scan before operation. On the basis of results, they were divided into two groups: 20 patients with and 26 patients without chronic ischemic heart disease.
