title: [Health surveillance in workers with a previous exposure to asbestos: a method of retrospective evaluation of exposition].
abstract: The medical surveillance of the previously exposed to asbestos like method of retrospective appraisal of the exposure. The medical surveillance of the previously exposed to asbestos is effected on indication of the Competent Physician by the DL 257/2006. An aspect that often countersigns such typology of surveillance is the lack of relative data about past environmental asbestos exposure. There've been submitted to sanitary controls 140 subject employees in a steel metal company where in past activity of heavy carpentry has been developed. All the subjects have been submitted in the period 1998-2007 to medical visit, PFR with DLCO, radiography of the chest, in some cases TC and BAL. The past exposure has been resulted inclusive between 1962 and 1981. None of these workers has developed asbestosis, while the 10% of the subjects have showed bilateral pleural plaques. 12 subjects have been submitted to close examination through BAL for the determination of the internal dose of asbestos with comparison of middle values of 3.9 ca /ml. Four cases of pulmonary neoplasm and any case of mesothelioma have been diagnosed. This experience shows as the medical surveillance of a homogeneous group of workers can furnish useful data also to frame previous asbestos exposure in absence of environmental data.
