Letter concerning: 'Response to: 'The epidemiology of malignant mesothelioma in women: gender differences and modalities of asbestos exposure by Marinaccio et al

Finkelstein1 invited physicians and researchers interested in mesothelioma to investigate on past usage of talcum powders by affected people. In Italy, asbestos contamination in talc for industrial use has been documented,2 and, as he underlines tremolite contamination at low levels of cosmetic and pharmaceutical talc has been reported in USA by Blount3 and Gordon and colleagues.4

In the Italian National Mesothelioma Register (ReNaM), the analysis of intensive exposure to talc has been evaluated with respect to occupational and environmental history. The catalogue of possible asbestos exposure circumstances (a tool for the interviewers) reports the potential presence of industrial talcs in quarries or mines working activities, in leather tanning and in rubber industries. The use of intensive cosmetic talc for personal use is evaluated by means of a structured questionnaire,5 as reported in the ReNaM guidelines (see https://www.inail.it/cs/internet/docs/all-linee-guida-renam.pdf%3Fsection=attivita, p82, p98, in Italian).
