A drowsy patient with a positive purple urine test.

We report a pitfall in the investigation of amphetamine poisoning by urine test. A 21-year-old female who came to hospital with drowsiness and was reported to have positive purple urine test. This false positive urine test occurred as a result of drugs and substances of the same structure. Specific investigations were further recommended in order to detect the use of the amphetamines and allow appropriate treatment.

A fatal case of benzyl benzoate poisoning.

We present a case of benzyl benzoate ingestion in a 38 years old Thai woman whose presenting symptom was coma and severe metabolic acidosis. The amount ingested was 360ml of 25%W/V benzyl benzoate. It did not contain any alcohol or acid substance. Standard textbooks and other reference books do not mention severe symptoms caused by ingestion of given this substance and gastric lavage is the only recommendation. Should there be another method used to induce elimination of benzyl benzoate-hemodialysis?
