[Life-threatening metabolic acidosis after ingestion of fire extinguisher powder]. / Lebensbedrohliche Acidose nach Ingestion von ABC-Löschpulver.

We present the case of a 31-year old male with ingestion of fire extinguisher powder in an attempted suicide. After consulting several poison information centres, the intoxication was initially classified as harmless; nevertheless, the patient was admitted to our intensive care unit for cardiopulmonary monitoring. Subsequently, due to the ingestion of ammonium sulphate and ammonium dihydrogen phosphate containing powder the patient developed severe metabolic acidosis with distinct electrolyte imbalance that required temporary haemodialysis.

DON-glycosides: Characterisation of synthesis products and screening for their occurrence in DON-treated wheat samples.

DON-3ß-glucopyranoside was synthesized and characterized by LC-MS/MS. The formation of by-products in the chemical synthesis was further evaluated and, according to their different fragmentation behaviours, it was possible to postulate their structures. The occurrence of these substances in nature was investigated by the analysis of wheat ears, which were treated with DON at anthesis. For the first time DON-3-glucoside could be detected in wheat, strongly indicating that it could also occur in naturally contaminated cereals.
