Exposition to Wood Dust
Conditions
Brief summary
The purpose is to evaluate feasibility of medical supervision of professionally active asymptomatic wood workers with questionnaires and nasofibroscopy. Secondary purposes are: * Feasibility evaluation of identification of former and actual professional expositions to wood dust and to various naso-sinusal carcinogenics in case of co-expositions (formaldehyde, chrome, nickel, leather) * Description of abnormal symptoms identified by occupational doctor and needing an otorhinolaryngology test * Description of results and examinations induced by nasofibroscopy in symptomatic or asymptomatic individuals: counting of naso-sinusal adenocarcinoma cases * Evaluation of participation of workers retiring in 2 years after inclusion to medical supervision program * Evaluation of information flow among different players * Assessment of costs induced by this targeted screening: direct medical costs (screened pathologies, induced additional examinations…) and indirect costs for company (duration of worker absence for transfer, medical and additional examinations).
