ABSTRACT

Using incidence, survival and mortality we tried to verify the effectiveness of mass-screening interventions for cervical uterine, breast, and colorectal cancer in females. Mortality data concern the period from 1978-2002. Incident cases derived from an ad hoc survey for 1978-1982 data and from the RTUP from 01/01/1994 to 31/12/2002. Relative survival rates were calculated for 1978-1982, 1994-1997 and 1998-2002 time intervals. All standardized mortality figures showed a steady trend. Incidence rates concerning cervical uterine cancer showed a decrease starting from the 1978-1982 period, whereas those for breast cancer had a constant increasing trend, and those for colorectal cancer increased up to 1997-1999 and later remained constant. For breast cancer the 5-year survival rate increased about 15% compared to the first period, for colon cancer there was less of an increase and the increase for cervical uterine cancer survival was only for the 1998-2002 period compared to the former ones. With constant incidence rates, improvement in survival from cervical uterine cancer may be due to a high number of cancer cases detected at an early stage. The effect of breast cancer screening on incidence is evident, though differences still did not influence mortality and survival. Colorectal cancer epidemiology can be considered as a prescreening pattern. Mortality, incidence and survival data allow a good overview for the effectiveness of screening procedures.

ABSTRACT

Differences in gynaecological cancer incidence and mortality in the urban and rural areas of the Umbria region (central Italy) were investigated. All women with primary invasive breast cancers, uterine cervix and uterine corpus, and ovarian cancers diagnosed during the periods 1978-1982 and 1998-2002 were identified and analysed according to place of residence (either urban or rural). Mortality data were supplied by the National Institute of Statistics (ISTAT) for the period 1978 to 1982, whereas for the 1994-2002 period they were supplied by the Regional Nominative Causes of Death Registry (ReNCaM). Incident cases considered were taken from an ad hoc survey for the first period and from the Umbrian Population Cancer Registry database for the second one. For each site the age-adjusted incidence (AAIR) and mortality (AADR) rates were calculated. The expected number of rural cases was obtained from indirect standardisation with urban incidence and mortality rates of several sites. The significance of the observed expected ratios (SIRs for incidence and SMRs for mortality) and the corresponding 95% confidence intervals were based on the Poisson distribution. Urbanisation levels were established following the classification of the Italian Institute of Statistics. For all sites, excluding the ovary during the most recent period, the SIR relative to rural areas was below 1, but the rates were statistically significant only for breast cancer in both periods (SIR 0.81, 95% CI 0.74-0.88 and SIR 0.82, 95% CI 0.77-0.88, respectively) and for cervix uteri in the first period (SIR 0.77, 95% CI 0.59-0.94). The lower breast cancer incidence in the rural area could also be due to lesser compliance with screening procedures which, up until 2002, were not provided in the form of mass-screenings throughout the region by the Regional Health Department. These results underscore the need for continued efforts to provide preventive health services to medically underserved women throughout Umbria, including rural communities. Underutilisation of preventive healthcare services may result in failure to identify healthcare problems that might be successfully managed with medication or lifestyle changes, as well as missed opportunities to prevent potentially life-threatening diseases.

ABSTRACT

Occupational exposure to chromium may cause airway inflammation and bronchial asthma. In this study we investigated the effect of chromium on the respiratory tract of exposed and non-exposed electroplating workers using spirometry and analysis of induced sputum (IS), exhaled breath condensate (EBC) and nasal lavage fluid (NLF). In both groups spirometry was normal; chromium in induced sputum was higher in exposed workers (7.90 +/- 0.855 microg/L, vs 1.78 +/- 0.075 microg/L; p<0.001); no significant difference was found in induced sputum cellularity. Median nitrite concentration in EBC was significantly higher in exposed subjects (4.35 micromol/L, 5 degrees -95 degrees percentile: 1.88-10.13 vs 0.11 micromol/L, 5-95 percentile: 0-0.72) (p<0.001). IL-6 and TNF-alpha were not detectable in EBC. Median IL-6 concentration in nasal lavage fluid was higher in exposed workers (5.72 pg/ml, 5-95 percentile: 0-65.25 pg/ml vs 0.28 pg/ml, 5-95 percentile: 0-1.7 pg/ml) (p<0.01). No differences in Eosinophil Cationic Protein concentration were found. TNF-alpha was not detectable in NLF. Chromium in induced sputum correlated with nitrites in EBC. For the first time three non-invasive methods were used to assess changes in respiratory tract in workers exposed to chromium. The results suggest chromium exerts an inflammatory/irritative action on airways.

ABSTRACT

The present study investigated the sources of discomfort and the symptoms reported by earthquake victims residing in temporary emergency prefabricated accommodation (prefab). The investigation was carried out by means of a questionnaire. 203 prefab occupants and 13 inhabitants of houses, who were chosen as reference population, replied in winter and 233 prefab occupants and 154 inhabitants of houses replied in summer. In both seasons more people living in prefabs indentified dry air, stuffy air, stale air, dust, dampness, uncomfortable temperature and bad odours as sources of discomfort. They also complained of general symptoms (headache, irritablility, insomnia, difficulty in concentration) and irritative symptoms of the eyes, upper and lower airways and skin. Multiple regression analysis identified the type of accommodation as the variable that most influenced the onset of general, ocular, upper and lower airway symptoms. Intrinsic characteristics of the prefabs (being constructed with synthetic materials, combustion sources, poor ventilation and insulation) and psychosocial factors e. losing their home, could have contributed to the onset of symptoms.
