Symptomatology caused by exposition to formaldehyde in medical students, and its pathophysiologic mechanisms

Abstract

Formaldehyde (FA) is used for preservation of anatomical specimens that are used during practices of Anatomy and Pathology. Emission of vapors of FA and direct contact with it often occur during such practices, thus exposing students and instructors to this substance. Clinical manifestations of this exposition are mainly respiratory and cutaneous. Therefore, FA constitutes an occupational risk for the health of exposed individuals. This article is a review of recent literature on this subject focused on the clinical manifestations associated to FA exposition and their pathophysiological bases. Protection measures are also included.
