Respiratory allergies on the staff of the police force.

The aim of the study was to evaluate respiratory allergies of an occupational nature in the staff of the police force. Five hundred and eighty-five subjects were submitted for lung function tests by dynamic spirometry. Subjects with a history of respiratory symptoms and border line respiratory function underwent bronchial provocation tests with methacholine. If FEV1 was < 80%, a bronchial reversibility test was performed. Allergic tests (skin and RAST) for inhalating allergens (perennial, seasonal and occupational) were performed. The results suggested asthmatic symptoms in 57 subjects, eight of whom were positive to skin and RAST tests for occupational inhalating allergens. Among these eight subjects, three had FEV1 < 80% of the theoretical value without therapy, and five showed obstruction of small caliber airways (MEF 25, MEF 50, FEF 25-75 < 65% of the theoretical value). The analysis showed a low percentage of respiratory occupational allergies. Among 21 subjects positive to Dermatophagoides, seven worked as archivists. In these workers, a concomitant occupational cause for the symptomatological and functional pattern was established.

[Accidents among ambulance employees: epidemiologic features].

The accidents have been esteemed that are verified in four years in a group of 824 employees. The study has underlined a meaningful percentage (30.1%) of road accidents. This suggests the opportunity of contemplate preventive actions: corrected maintenance of the ambulance, control of the conditions of environmental comfort, organization of the job, individualization of conditions that reduces the attention and the concentration, as the use of alcohol and of other substances.

[Noise exposure in the coffee industry in the light of current community standards].

And' is studied the noise exposure (with the calculation of the Lep,d) and the auditory function (with the method MPB 2002) in employed to the coffee's workmanship. The purpose was double. To deepen aspects a little studied thin to today and to compare the results with the "values limit of exposure" and the "values of exposure that make to go off the action" foreseen by the European directive 2003 of February 6th 2003. The data have underlined levels of noise below the inferior values of exposure that make to go off the action (80 dBAs) and absence of auditory effects from noise. The results suggest therefore the opportunity to extend the observations in other similar technological cycles, also to appraise other risks reported in literature as the cutaneous and respiratory allergies.

[Fanconi's anemia: in vitro tests for the individualization of heterozygotes].

Fanconi's anaemia (FA) is an autosomal recessive mutation associated with constitutional chromosome aberrations. Patient's cells show increased susceptibility to different mutagens, especially bifunctional alkylating agents. Asymptomatic heterozygotes have a population prevalence of 1 in 300, and have been considered at risk for cancers. It has also been shown that their cells are especially sensitive to some chemicals in vitro. Laboratory tests are presented and discussed which are adequate for FA heterozygotes identification and for understandings the basic defect of this mutation.

[Audiometry in the cellulose industry].

A noise level dosimetry and audiometric testing were conducted in a cellulose factory to determine the hazardous noise level and the prevalence of noise induced hearing loss among the exposed workers. The noise level was recorded up to 90 db (A) in several working areas. 18 workers, potentially exposed to noise injury, evidenced a significant hearing loss. While no evidence of noise injury was recorded in a control group of 100 subjects. This finding suggest a strict relationship between audiometric tests, the noise level recorded in the working place and the working seniority of exposed employers.
