Arsenic neuropathy.

Arsenic neuropathy in a young Thai male who accidentally drank a glass of arsenic solution was reported. Two hours after ingestion, he experienced nausea and vomiting. Ten days later, distal sensory loss and weakness developed. Symptoms and signs were progressive to the severity that the patient was functionally dependent. After five months on a rehabilitation programme, he regained functional independence although he still exhibited distal weakness.
