[Asbestos exposure assessment in the first case of intrasplenic mesothelioma]. / Accertamento dell'esposizione ad amianto nel primo caso di mesothelioma splenico.

BACKGROUND: In 2013 the International Journal of Surgical Pathology published a case report of intrasplenic malignant mesothelioma (MM) in a 48-year-old man: it was the first report in literature describing a case of primitive intra-splenic MM, described without  a history of asbestos exposure. OBJECTIVE: To verify the possible past exposure to asbestos, ignored by the patient himself, by studying in depth his environmental and occupational history. METHODS: Information about the occupational and non-occupational history of the subject was collected by Experts of the Operational Unit of Occupational Health and Safety Control (UOC PSAL) of the Local Health Unit Umbria 1 - Perugia, using the Italian National Mesothelioma Register (ReNaM) questionnaire and guide lines; an inspection was  carried out at the past canning industry where the patient worked in the period 1982-1990 and material was taken to be analysed by MOCF and SEM. RESULTS: Samples showed the presence of asbestos  fibres belonging to the amphibole class (amosite and crocidolite) and to the serpentine class (chrysotile). CONCLUSIONS: The survey described the past occupational exposure to asbestos in a canning industry, where  the subject worked in the period 1982-1990,  unknown to the patient himself. The authors strongly confirm the  usefulness of standardized methods, such as the ReNaM Questionnaire, and the importance of technical expertise of the investigator to find and analyse the suspect materials and to demonstrate  possible past occupational exposure to asbestos.

[Results of an alcohol breath-test campaign in a sample of construction site workers in the Umbria region]. / Risultadi di una campagna di controlli alcolimetrici in un campione di lavoratori di cantieri edili della regione Umbria.

OBJECTIVE: The purpose of the research was to evaluate the respect of the regulation on the prohibition of alcohol consumption in the building sector through an alcohol breath test campaign, and to acquire information on the alcohol consumption by the contractors. METHODS: In the course of the investigation which covered the period 2011-2013, in a sample of construction, it was decided to access with verification of the presence of alcoholic beverages, administration workers to an anonymous questionnaire on alcohol consumption, execution of alcohol breath test. RESULTS: The reached population consisted in 1635 subjects, 1040 of which Italians and 595 foreigners; the consumers of at least 0,5 AU/die resulted being 354 among Italians and 250 among foreigners (p<0,05), the main occasion of consumption was observed being the meal for 39,8% of subjects; wine, followed by beer, were recorded as the most consumed beverages. The great majority of subjects, 1340, declared being aware of the regulation on the prohibition of alcohol consumption and only a minimum part of it, 42 subjects, declared having occasionally consumed alcoholic beverages for more than 6 AU, or having driven a car, 3 subjects, after having consumed at least 2 AU, or having had interviews, 115 subjects, about alcohol consumption with healthcare operators. The alcohol test results only marked 91 cases (5,6%) of positiveness with values mostly confined to 0,2 g/l, and the distribution of positive tests resulted substantially overlapping (p>0,05) between foreigners and Italians. Notwithstanding, among the negative subjects, 9% declared having consumed alcoholics during the meal immediately preceding the work shift; all this underlining a sound dangerous behaviour. A behaviour which may easily escape to an alcohol metric test, considering the relationship between the timing of the last alcohol consumption, the quantity assumed, the test timing and its result. CONCLUSIONS: The authors conclude pointing out how, in the studied sector, there certainly is a great tendency to respect the regulation on the prohibition of alcohol consumption, and how there is a reliable modification with regards to alcohol among the behavioural models traditionally allocated to building contractors, with a strong reduction of consumption as in working as in non-working hours. Notwithstanding, the authors may want to underline the persistency of dangerous behaviours worthy promotion, information and education actions. Besides, they advise and wish for additional interventions by the legislator, directed to better define the boundaries of the prohibition and impose in such boundaries an alcohol test level equal to 0 during the working hours.
