An elderly patient with severe acute renal failure due to sodium bromate intoxication.

Accidental or deliberate ingestion of bromate solution has been reported in pediatric as well as adult cases; however there have been no reports of such intoxication in the elderly. We report a 78-year-old woman who suffered severe acute renal failure due to the accidental ingestion of sodium bromate solution. The patient was successfully treated with hemodialysis therapy and renal function recovered without hearing loss.
