Cancer mortality in a cohort of asbestos textile workers.

A cohort of 889 men and 1077 women employed for at least 1 month between 1946 and 1984 by a former Italian leading asbestos (mainly textile) company, characterised by extremely heavy exposures often for short durations, was followed up to 1996, for a total of 53,024 person-years of observation. Employment data were obtained from factory personnel records, while vital status and causes of death were ascertained through municipality registers and local health units. We observed 222 cancer deaths compared with 116.4 expected (standardized mortality ratio, SMR=191). The highest ratios were found for pleural (SMR=4105), peritoneal (SMR=1817) and lung (SMR=282) cancers. We observed direct relationships with duration of employment for lung and peritoneal cancer, and with time since first employment for lung cancer and mesothelioma. Pleural cancer risk was independent from duration (SMR=3428 for employment <1 year, 7659 for 1-4 years, 2979 for 5-9 years and 2130 for > or =10 years). Corresponding SMRs for lung cancer were 139, 251, 233 and 531. Nonsignificantly increased ratios were found for ovarian (SMR=261), laryngeal (SMR=238) and oro-pharyngeal (SMR=226) cancers. This study confirms and further quantifies the central role of latency in pleural mesothelioma and of cumulative exposure in lung cancer.

Fluorescence polarization assay for the diagnosis of bovine brucellosis: adaptation to field use.

A fluorescence polarization assay (FPA) was used to test whole blood samples prepared by mixing blood cells from cattle without exposure to Brucella abortus (B. abortus) with sera from animals with confirmed (bacteriologically) infection. A cut-off value between negative and positive values was initially established to be 87.2mP. This value was changed to 95mP to increase assay specificity without loss of sensitivity when testing blood samples from negative animals. The FPA technology was applied to whole blood samples in the field and to stored whole blood samples using two diluent buffers. Relative sensitivity and specificity values for the FPA performed in the field, based on buffered antigen plate agglutination test and competitive enzyme immunoassay results were 95.3 and 97.3%, respectively. However, to obtain maximum sensitivity and specificity, a cut-off value of 105mP was determined for fresh whole blood samples. The relative sensitivity and specificity values of the FPA when testing stored whole blood samples were 100% each using a 95mP cut-off.The usefulness of the FPA for testing whole blood samples in the field was demonstrated.

Epidemiological aspects of poisoning in children observed over a 10-year period.

During 10 years of activity at our Service, we collected 1867 cases of poisoning in children. Our observations concern only subjects hospitalized at our Institute and do not include phone call consultations. Our experience confirmed a higher number of poisonings among males. As far as age was concerned, the highest percentage of cases involved children under five, with a peak between 2 and 3 years of age. A fairly high incidence (8%) of "passive" poisonings was found in infants in their first year of life as a consequence of mistakes by the mother or other people taking care of the child. Voluntary poisonings, occurring in children aged 9 or more, often involved females and accounted for 2.1% of the total. Drugs are the main cause of poisoning in children, followed by household products and by a group of different substances (spoiled foods, nonedible mushrooms, alcoholic beverages). The lowest number of poisonings occurred on Sundays. The time of the day when most accidental poisonings occurred ranged from 10:00 AM to 12:00 noon and from 6:00 to 8:00 PM. Most poisonings took place in the kitchen. The colors preferred by children are white and pink.
