[Asbestos exposure assessment in the first case of intrasplenic mesothelioma].

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 of an alcohol breath-test campaign in a sample of construction site workers in the Umbria region].

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.

[Levels of exposure to respirable fibres at worksites for abatement of compact and friable asbestos].

Background: Starting from a project aimed at assessing the carcinogenic risk in some industrial sectors covered by Local Health Authority No.1 (LHA) in Perugia (USL Umbria1, Italian acronym), worksites for abatement of materials containing asbestos (MCA) were examined in order to estimate respirable fibres exposure levels in workers. Abatement work is, indeed, a fast developing sector, but is not free from asbestos risks in the long-term, particularly carcinogenic risks; this kind of work therefore requires maximum effort in respecting prevention standards prescribed in the relative legislation.

[A survey on workers' individual exposure to crystalline silica in the building industry].

Background: The wide-spread presence of silica in nature and the variety of materials containing it cause crystalline silica exposure of workers in various industrial activities. Moreover crystalline silica is classified as carcinogenic to humans (Group 1) by IARC, in relation to its possible lung carcinogenicity.

Objectives And Methods: The purpose of this paper was to assess respirable particles and crystalline silica exposure of workers in a number of some building sites located in the area of a Local Health Unit in the Umbria region.
