Mortality study of employees in a factory of recovery and refining of catalytic converters in Rome, Italy.

The study objective is to describe cause specific mortality of employees in a plant engaged in production, recovery and refining of catalytic converters located in Rome. Previous epidemiological studies conducted in similar plants are not available. A total of 828 workers (642 males and 186 females) were followed up between 1956 and 31-12-2003. Cause specific standardized mortality ratio (SMR) and 90% confidence intervals (CI) were computed using regional rates for comparison. Among males hired between 1956 and 1993, followed up until 31/12/2003, mortality for all causes (SMR 0,8; 90% CI 0,7-1,0; 85 observed) and all neoplasms (SMR 0,6; 90% CI 0,42-0,87; 20 observed) is below expected; an increase is present for liver cirrhosis (SMR 2,74; 90% CI 1,47-5,1; 7 observed) and brain cancer (SMR 5,24; 90% CI 2,3-11,90; 4 observed). The present investigation complies with the proposed scientific standards for occupational cohort studies. The study was not prompted by well defined a priori hypotheses but it is included in a process intended to typify a potentially polluted site; the absence of a priori hypotheses and of previous epidemiological evidence, prevent from a causal interpretation of the increased mortality from liver cirrhosis and brain cancer. The implementation of cohort studies in industrial sites where industrial activities similar to the one here examined are present, are highly recommended.

[Feasibility of behavioural interventions for tobacco smoking cessation in routine general practice]. / Intervento motivazionale del medico di medicina generale nel processo di disassuefazione dal fumo di tabacco.

The aims of this study were: 1) to evaluate a training course on smoking cessation techniques offered to general practitioners of the RMB Local Health Unit (Rome, Italy) 2) to evaluate the feasibility of delivering brief counseling interventions during routine primary care practice and 3) to evaluate factors associated with modification of smoking habits. In total, 166 GPs participated in the training courses. Of these 60 GPs (36.1%) voluntarily agreed to take part in the study. A total of 3280 patients were enrolled and given a brief counseling intervention ("ask-advise"). Six months later the same patients were asked to complete a questionnaire, 24% responded. Approximately 24% of those who responded had quit smoking and over 43% had either reduced the number of cigarettes or attempted to quit. Of the subjects who modified their smoking behaviour (quit, attempted to quit, or reduced the numbers of cigarettes smoked) following the "ask-advise" intervention, 10% had also used drug therapy, while approximately 4% did so only with their doctor's assistance. Smoking cessation interventions incorporated into routine consultations in general practice are feasible and relevant from a public health perspective.

[An intervention model for smoking prevention strategies]. / Strategie di prevenzione del tabagismo:un modello di intervento.

Tobacco smoke represents the main cause of preventable morbidity and mortality in Western countries: in Italy, approximately 85.000 persons die each year because of smoke-related illnesses. Starting from the objectives defined by the 2001/2003 National Healthcare Plan, the Department of Prevention of the "Roma B" Local Health Unit elaborated a three-year project for the fight against tobacco smoke. The general objectives of the project are: to prevent young people from starting to smoke, to promote stop-smoking initiatives (with the involvement of General Practitioners) and to protect non-smokers from passive smoking (in the context of a smoke-free health facilities program). A special technical-scientific committee was set up to evaluate the effectiveness of the smoking prevention interventions.
