[The role of the public health personnel in the Prevention Department (in the Hygiene Services and Public Health Care and Hygiene of Food and Nutrition): proposal for the future of public health care]. / Il ruolo del medico di sanità pubblica del Dipartimento di prevenzione (nei servizi di Igiene e Sanità Pubblica e Igiene degli Alimenti e Nutrizione): una proposta per il futuro della sanità pubblica.

A global and local discussion on Public Health relevance is taking place, including the future role and organization of its services. Noteworthy becomes the role played by Public Health Specialists. This work presents the results of a workshop, carried out following the Guilbert methodology, whose aim was to define Public Health Doctors functions and their related activities. The programme involved 30 professionals from Triveneto area (North Eastern Italy), working in Prevention Departments at National Health Service and Universities. The key-functions identified were: 1) Health status assessment and identification of community risk factors, 2) Health Promotion, 3) Prevention, 4) Protection, 5) Planning, 6) Communication, 7) Professional Training, 8) Alliances and resources for complex Public Health programs, 9) Crisis management in Public Health, 10) Research. For each function activities were identified, meaning concerning areas and contents that must be warranted by professionals. This experience allowed to share existing attitudes and experiences present in Triveneto area, and it can stand as a feasible instrument for different settings. Nevertheless, it appears mandatory explaining at each level in the society role and functions of Prevention Departments.

The cytological screening turned out effective also for adenocarcinoma: a population-based case-control study in Trento, Italy.

To evaluate the effectiveness of a cytological screening to prevent invasive cervical cancer in the province of Trento, a northern Italian area where a population-based cancer registry is active. The history of Pap test was evaluated through a case-control study in 61 population-based invasive cervical cancer patients, incident during 1995-2000, and in 244 age-matched (between 25 and 75 years old) controls. Women who had at least one Pap test had a reduced risk of invasive carcinoma of 80% (odds ratio=0.20; 95% confidence intervals 0.10-0.40). The protection of a previous Pap test for both squamous cell carcinoma (odds ratio=0.23; 95% confidence intervals 0.09-0.58) and adenocarcinoma (odds ratio=0.24; 95% confidence intervals 0.07-0.78) was similar. The overall protective effect of the Pap test was not seen among younger women (<40 years). The protective effect of the Pap test seems to be stronger for shorter intervals. Our study confirms that Pap-test screening, particularly in middle-aged and older women, is an effective public health intervention with encouraging results also for the prevention of cervical adenocarcinoma.

A case-control study of occupational exposures and systemic sclerosis.

OBJECTIVES: A case-control study was conducted in Verona, Italy, to assess the relationship between occupation, occupational exposures and systemic sclerosis (SSc). METHODS: Fifty-five cases (46 female and nine male) and 171 controls were recruited. Interviews provided work histories, including job titles, industry and likelihood of occupational exposure to silica, hand-arm vibration, organic solvents, and other chemicals. Odds ratios (ORs) and 95% confidence intervals (95% CI) were estimated. RESULTS: Female teachers (OR 3.4, 95% CI 1.2-10.1) and textile workers (OR 2.1, 95% CI 1.0-4.6) were at an increased risk of SSc. Compared with those never exposed, age-adjusted and gender-adjusted ORs were 2.3 (95% CI 1.0-5.4) among subjects exposed to organic solvents, 2.5 (95% CI 0.8-8.0) for exposure to selected chemicals, 1.7 (95% CI 0.4-7.6) for exposure to silica, and 1.5 (95% CI 0.5-4.8) for usage of vibrating tools. When data analysis was stratified according to gender, only men showed a significant increase in risk for exposure to solvents and selected chemicals. CONCLUSIONS: The findings of this study tend to support the role of organic solvents and certain chemicals in SSc causation. The association with teaching and working in the textile industry suggests that other exposures are involved in the aetiology of SSc among women. However, because of the small number of subjects, particularly in stratified analyses, chance cannot be ruled out as an explanation of some findings of this study.

Reproductive factors and the risk of scleroderma: an Italian case-control study.

OBJECTIVE: To investigate the association between scleroderma (systemic sclerosis; SSc) and reproductive factors in a hospital-based case-control study conducted at the University Hospital of Verona in Northeastern Italy. METHODS: Forty-six confirmed cases of SSc in women (42 with diffuse SSc and 4 with limited SSc) and 153 female control subjects with orthopedic disorders were recruited at the University Hospital. For each subject, information on age at first pregnancy, number of children and abortions, and use of oral contraceptives was obtained by means of a structured questionnaire, and information on the subject's occupational history and lifestyle factors was also sought. RESULTS: Parous women had a reduced risk of SSc (age-adjusted odds ratio [OR] 0.3, 95% confidence interval [95% CI] 0.1-0.8) compared with nulliparous women. The risk decreased with an increasing number of children: the age-adjusted OR was 0.6 (95% CI 0.2-1.7) for those women who had had 1 child, 0.3 (95% CI 0.1-0.7) for those having had 2 children, and 0.3 (95% CI 0.1-0.8) for those having had 3 or more children. Abortive pregnancies were inversely related to SSc risk: for women who had an abortion, the OR was 0.5 (95% CI 0.2-1.5) compared with women with no history of abortion. The overall history of any pregnancy (abortive or age-adjusted complete) was associated with a reduced risk of SSc (age-adjusted OR 0.3, 95% CI 0.1-0.7). CONCLUSION: Since the incidence of SSc is higher in women and has its peak after childbearing age, it has been hypothesized that immunobiologic modifications during pregnancy may be associated with SSc development. Our findings showing a reduced risk of SSc among parous women seem to exclude the possibility of pregnancy itself as a risk factor for SSc. The role of HLA compatibility between the mother and the fetus, however, should be evaluated in further research.
