Case ReportsSevere lactic acidosis in a diabetic patient after ethanol abuse and floor cleaner intake.
An intoxication with drugs, ethanol or cleaning solvents may cause a complex clinical scenario if multiple agents have been ingested simultaneously. The situation can become even more complex in patients with (multiple) co-morbidities. A 59-year-old man with type 2 diabetes mellitus (without treatment two weeks before the intoxication) intentionally ingested a substantial amount of ethanol along with ~750 mL of laminate floor cleaner containing citric acid. ⋯ Metabolic acidosis in diabetes is multi-factorial, and the clinical situation may be further complicated, when ingestion of ethanol and toxic agents are involved. Here, we reported a patient in whom diabetic ketoacidosis was accompanied by severe lactic acidosis as a result of citric acid and mainly ethanol ingestion and a possible thiamine deficiency. In the presence of lactic acidosis in diabetic ketoacidosis, physicians need to consider thiamine deficiency and ingestion of ethanol or other toxins.

Influence of UGT2B7, OPRM1 and ABCB1 gene polymorphisms on postoperative morphine consumption.
Therapeutic modulation of pain with morphine and other opioids is associated with significant variation in both effects and adverse effects in individual patients. Many factors including gene polymorphisms have been shown to contribute to the interindividual variability in the response to opioids. The aim of this study was to investigate the significance of UGT2B7, OPRM1 and ABCB1 polymorphisms for interindividual variability in morphine-induced analgesia in patients undergoing hysterectomy. ⋯ The genotype distribution was similar between the forensic cases and the patients. However, the mean concentration of morphine was higher in forensic cases compared to patients. We conclude that gene polymorphisms contribute significantly to the variation in morphine concentrations observed in individual patients.
