Docetaxel is an antineoplastic agent widely used in therapeutics. The objective of this study was to develop and validate a routine assay, using liquid chromatography coupled to tandem mass spectrometry (LC/MS/MS), for the simultaneous quantification of docetaxel and its main hydroxylated metabolites in human plasma. A structural analogue, paclitaxel, was(More)
To evaluate the prevalence of serum and erythrocyte magnesium (Mg) abnormalities in patients on admission to the intensive care unit (ICU) and to test the hypothesis that low levels of Mg are associated with a higher mortality. Prospective study. 14-bed ICU in a 1000-bed teaching hospital. 179 consecutive patients admitted over a 4-month period. Total serum(More)
Studies by laser-Doppler flowmetry of middle ear microcirculation changes induced by physical and chemical stimuli in the animal have only recently been made. This prospective study, performed in humans, was designed to compare the effects of a postural manoeuvre (headup tilt 30°), hypotension and locally applied vasoconstriction on middle ear blood flow(More)
Tolerance of intraperitoneal chemohyperthermia (IPCH) with mitomycin C (2 mg/kg) by irrigation of the peritoneal cavity via a closed circuit system was evaluated in Beagle dogs for possible use in the management of human peritoneal carcinomatosis. Of dogs, 24 underwent three digestive anastomoses each. They were randomized into three groups: control (n =(More)
Miglustat (OGT 918) is an iminosugar recently introduced in therapeutic as potential alternative therapy in disorders found in several diseases such as Tay-Sachs, Gaucher or Niemann-Pick diseases. A highly sensitive liquid-chromatography-electrospray tandem mass spectrometry (LC-MS/MS) assay was developed for the quantification of miglustat in human plasma(More)
The characteristics of benzodiazepine binding sites (affinity, number heterogeneity) were studied on frozen sections of hippocampus of 7 suicides and 5 controls subjects, using biochemical and autoradiographic techniques. 3H flunitrazepam was used as ligand, clonazepam and CL 218,872 as displacing agents. Some neurotransmitters or their derivatives (GABA,(More)
PURPOSE To determine whether remifentanil, combined with propofol, could induce controlled hypotension, reduce middle ear blood flow (MEBF) measured by laser-Doppler flowmetry, provide a "dry" operative field, and could be compared with nitroprusside or esmolol combined with alfentanil and propofol. METHODS Thirty patients undergoing tympanoplasty and(More)
A gas chromatographic-mass spectrometric assay, using selected-ion monitoring (GC-MS-SIM) with thymol as internal standard, was developed for quantitating propofol, an intravenous anaesthetic. The method described is rapid and sensitive for the determination of propofol in whole blood. The sensitivity of the present method is 10 ng/ml. The recovery of(More)
The EMIT-TOX Enzyme Immunoassay for benzodiazepines was evaluated. Reproducibility, linearity, accuracy, sensitivity, and interferences were tested and found to be in good agreement with the manufacturer's specifications. Furthermore, the reactivity of 15 benzodiazepines were studied. According their differential reactivity, the 15 benzodiazepines can be(More)
The director of a laboratory has to be sure to give out reliable results for routine tests on automatic analysers regardless of the clinical context. However, he may find hyperbilirubinaemia in some circumstances, parenteral nutrition causing turbidity in others, and haemolysis occurring if sampling is difficult. For this reason, the Commission for(More)
