Lazio region (5.15 million, including Rome, 2.8 million), Italy.To monitor pulmonary tuberculosis (TB) epidemiology from 1997 to 2003.We used data from the mandatory National Infectious Diseases Surveillance system, the regional Hospital Information System and the regional Mortality Register. The number of prevalent pulmonary TB cases hospitalised was determined by linking notifications and hospitalisations. To estimate incidence, we excluded all cases with previous TB hospitalisations since 1995, and those reported as a secondary diagnosis in the Hospital Information System. Mortality rates were ascertained from mortality records reporting TB as the principal cause of death.The record linkage identified 4885 incident cases, 9010 hospital prevalent cases and 217 deaths. Incidence decreased from 15/100000 in 1997 to 11 in 2003, and consistent decreases were also observed in hospitalisation prevalence and mortality (P for trend0.0005,0.0005 and =0.063, respectively). The number of AIDS-related TB cases dropped from 85 to 49 (P0.0005). The number of incident cases in non-Italians increased significantly, from 171 to 267 (P0.0005). Notification underreporting was estimated at 39%.Despite a decreasing trend, TB incidence is still over 10/100000 in Lazio region. Targeted interventions for immigrant populations are essential for controlling TB.

Aim of the study is to describe the characteristics of road, home and work-related traumas among adult immigrants born in non-industrialised Countries, and to compare the consequent probability of hospitalisation with Italian adults in Lazio Region, year 2000. Source of data is the Emergency-based Surveillance System, which collects all the emergency ward visits in Lazio region. Accident incidence has been estimated using alternatively the residence permits and the roman resident population born in non-industrialised Countries. The 7.7% of all the emergency visits of immigrants are trauma-related. Road traffic accident visits are more appropriate and urgent. Immigrants have a higher risk of hospitalisation both for road and home accidents compared to the Italians (OR = 1.59 and OR = 1.37 respectively). Immigrants use emergency wards for severe and urgent trauma-related accidents, they have higher probability of hospitalisation compared to the Italians. Our analysis highlights the necessity to improve tools to study immigrant health.

We evaluated the association between exposure to environmental tobacco smoke (ETS) from husbands who smoke and plasma levels of antioxidant vitamins among nonsmoking women. A total of 1249 women from four areas in Italy answered a self-administered questionnaire, reported their diets on a food frequency questionnaire, had a medical examination, and gave their blood for alpha and beta-carotene, retinol, L-ascorbic acid, alpha-tocopherol, and lycopene determinations. Urinary cotinine was used to evaluate the level of recent exposure to ETS. After adjusting for study center, age and education, we found no association between ETS exposure and daily nutrient intake of beta-carotene, retinol, L-ascorbic acid, and alpha-tocopherol. However, we found an inverse dose-response relationship between intensity of current husband's smoke and concentrations of plasma beta-carotene and L-ascorbic acid. The associations remained even after controlling for daily beta-carotene and vitamin C intake and for other potential confounders (vitamin supplementation, alcohol consumption, and body mass index). Moreover, when urinary cotinine was considered as the exposure variable, a significant inverse association with plasma beta-carotene was found. The findings may be of interest to explain the biological mechanism that link ETS exposure with lung cancer and ischemic heart diseases.

OBJECTIVES: Studies seeking direct estimates of the lung cancer risk associated with residential radon exposure lasting several decades have been conducted in many European countries. Individually these studies have not been large enough to assess moderate risks reliably. Therefore data from all 13 European studies of residential radon and lung cancer satisfying certain prespecified criteria have been brought together and analyzed. METHODS: Data were available for 7148 persons with lung cancer and 14,208 controls, all with individual smoking histories and residential radon histories determined by long-term radon gas measurements. RESULTS: The excess relative risk of lung cancer per 100 Bq/m3 increase in the observed radon concentration was 0.08 [95% confidence interval (95% CI) 0.03-0.16; P=0.0007] after control for confounding. The dose-response relationship was linear with no evidence of a threshold, and it remained significant when only persons with observed radon concentrations of
