Occupational hypersensitivity pneumonitis in a smelter exposed to zinc fumes.
نویسندگان
چکیده
A smelter exposed to zinc fumes reported severe recurrent episodes of cough, dyspnea and fever. Bronchoalveolar lavage showed a marked increase in lymphocytes count with predominance of CD8 T-lymphocytes. Presence of zinc in alveolar macrophages was assessed by analytic transmission electron microscopy. This is the first case of recurrent bronchoalveolitis related to zinc exposure in which the clinical picture and BAL results indicate a probable hypersensitivity pneumonitis.

Fatal chemical pneumonitis due to cadmium fumes.
Acute exposure to high concentrations of cadmium fumes may cause acute chemical pneumonitis with a possibly fatal outcome. The etiologic diagnosis of acute cadmium intoxication from inhaled fumes may be difficult and can be confused with other forms of acute respiratory failure. We report on a case of a fit 53 year-old man who was exposed to cadmium fumes after flame-cutting an alloy containing...
