Background: A classification of 12 work categories was used to evaluate the cancer incidence and mortality among a cohort of Swedish rubber tire workers.
Methods: Cancer incidence and mortality in the cohort was compared with expected values from national rates. Standardized incidence and mortality ratios were calculated for the total cohort, for sub-cohorts and with the inclusion of a latency requirement.

Background: Malignant diseases but also cardiovascular and respiratory disorders and diabetes mellitus have been associated with work in pulp and paper production. The present cohort focuses on cardiovascular mortality in relation to various exposures in this industry.
Methods: The cohort, followed-up for mortality, includes 7,107 workers, 6,350 men and 757 women, from three major old mills in the middle of Sweden.

Background: If the occurrence of disease monotonically increases with the degree of exposure in an epidemiologic study, a dose-response (or exposure-response) relationship is indicated and facilitates the interpretation that the exposure has a causal role. It is not uncommon, however, that there is some effect in terms of an overall increased relative risk but no clear dose-response relationship.
Methods: Models presented here show that cumulative exposure, as involving the duration of exposure, is not an adequate parameter when more recent exposure or the intensity of the exposure plays the greater role for the disease outcome.

Associations between exposure to PVC plastics and testicular cancer have been reported. To improve the exposure-response analysis in a matched case-control study on testicular cancer and occupational exposures, a self-administered exposure questionnaire and expert assessment was applied and different exposure measures were developed. The questionnaires regarding work histories and employment in PVC production, manufacturing, and handling of PVC products were completed by 1582 subjects (90%).

We performed a case-control study in Lazio, a region in central Italy characterized by high levels of indoor radon, Mediterranean climate and diet. Cases (384) and controls (404) aged 35-90 years were recruited in the hospital. Detailed information regarding smoking, diet and other risk factors were collected by direct interview.
