title: Accidental acute mercury vapor poisoning.
abstract: Accidental acute mercury vapor poisoning in three persons is reported. Three hours after exposure, symptomatology began by chills, vomiting, diarrhea and chest pain. Two patients, respectively 67 and 77 year old, presented severe pulmonary edema, then neurological symptoms with tremor and coma. This toxic pulmonary edema, which entailed artificial ventilation, was followed in both cases by an acute interstitial pulmonary fibrosis which led to death respectively after six and sixteen days. In the third case (a thirty eight year old patient) a skin rash, erythematous and pustuliform was observed. Analysis for total mercury by flameless atomic absorption showed very high mercury levels in blood and urine of the three patients. The effect of treatment by Dimercaptopropanol on renal excretion of mercury was studied. Optic and electron microscopy of the lung of the two patients who died showed the pulmonary changes of acute interstitial fibrosis.
