Pharmacokinetics and pharmacodynamics of quetiapine in a patient with a massive overdose.

We present a case of massive overdose with the atypical antipsychotic quetiapine in a 34-year-old woman (body weight 65 kg). At admission, approximately 2 to 4 hours after ingestion of approximately 24 g of quetiapine, the patient was comatose (Glasgow Coma Scale score 5), requiring orotracheal intubation and transfer to the intensive care unit. Because of myoclonic jerks and generalized seizures, benzodiazepines were administered.

Clinical evaluation of the Elecsys CA 15-3 test in breast cancer patients.

The aim of the present study was to evaluate the clinical performance of the CA 15-3 assay on Elecsys systems in an international multicenter study (11 centers). A total of 1326 single samples (272 apparently healthy individuals, 34 pregnant women, 308 benign diseases, 273 cancers other than breast, 439 breast cancer) and 538 serial samples of 98 breast cancer patients during follow-up were analyzed. 95% of values in healthy individuals were below 25 kU/L, and 88% in benign breast diseases, respectively.
