A 47-year-old man had an episode of severe respiratory failure after acute intoxication with arsenic. Features of the initial clinical presentation included nausea, vomiting, and diarrhea, acute psychosis, diffuse skin rash, and marked pancytopenia. A peripheral neuropathy then developed which resulted in severe weakness of all muscles of the limbs, the shoulder and pelvis girdles, and the trunk. The neuropathy continued to progress despite treatment with dimercaprol (BAL in oil). Five weeks after the initial exposure, the patient was no longer able to maintain adquate ventilation and required mechanical ventilatory support. Improvement in the patient's neuromuscular status permitted successful weaning from the ventilator after one month of mechanical ventilation. Long-term follow-up revealed no further respiratory difficulty and slow improvement in the strength of the peripheral muscles.

1. We report two cases of acute mercury vapour intoxication in humans. The mercury vapour was released from smelting alloys (gold-mercury amalgam). The alloy was apparently contaminated with an unknown amount of mercury. 2. Within half an hour of the incident, the victims began having moderate headache, nausea, lumbar pain and shortness of breath at rest. The patients were treated with BAL (2,3 dimercaptopropanol), followed by DMSA (2,3 dimercaptosuccinic acid). 3. Serial measurements of mercury metal in plasma and in urine were made for ten days. 4. The results suggest that in spite of the treatment, relatively high concentrations of mercury remain in the plasma for a very long time, and this could be explained by the progressive release of mercury from red blood cells and tissues after oxidation. However, BAL and DMSA did not seem to be the most efficient antidotes. They reduce the plasma inorganic mercury uptake at concentrations of < 50 micrograms I-1.
