[Risk of nasopharyngeal cancer, Leukemia and other tumors in a cohort of employees and students potentially exposed to (FA) formaldehyde in University laboratories].

FA was recently classified as carcinogen of second class (category 1B). A retrospective cohort study was conducted for the evaluation of the association between exposure to FA and cancer in professionally potentially exposed in a University setting. The cohort was composed of 140 exposed to FA and 364 not exposed in the period 1999-2015.

[Changes in tobacco addiction and spirometric variations in workers exposed to chemical risk in biochemical research laboratories of a large Italian University--a retrospective cohort study].

Objective: To describe smoking cessation in a group of workers exposed to chemical risk and factors associated; to assess the changes of respiratory function over the years also in relation to risks to which they were exposed.

Materials And Methods: We studied employees/students occupationally exposed to chemical risk from whom we also had information about smoking status and who had done a spirometry in all periodic visits and who had at least two periodic medical examinations during the follow-up.

Results: Variables significantly associated to the smoking cessation are gender and exposure to biological risk.
