BACKGROUND Tyrosine Kinase Inhibitors (TKIs) are a class of targeted drugs for the treatment of malignant pathologies. The metabolic profile of these drugs can result in great interindividual variability, thus therapeutic drug monitoring (TDM) is of importance. Here, a rapid and specific method for quantification of nine TKIs in plasma samples is described.(More)
A high-performance liquid chromatographic method is described for the determination of selective serotonin reuptake inhibitors (fluvoxamine, paroxetine, sertraline, fluoxetine, citalopram, mirtazapine), serotonin norepinephrine reuptake inhibitors (milnacipram, venlafaxine), a noradrenergic and specific serotoninergic antidepressant (mirtazapine), and five(More)
Here we describe a liquid chromatography-tandem mass spectrometry method for the blood determination of tricyclic antidepressant drugs (amitriptyline, clomipramine, trimipramine, and imipramine, doxepin, mianserin, maprotyline, dosulepine, amoxapine), their active metabolites (desipramine, nortriptyline, demethylclomipramine, and nordoxepin), and monoamine(More)
BACKGROUND Telaprevir (TVR) is a protease inhibitor (PI) used in chronic hepatitis C treatment with pegylated interferon plus ribavirin. We analysed the prevalence and kinetic development of TVR resistance upon treatment. METHODS A total of 24 cirrhotic patients (genotype 1a, n=8; genotype 1b, n=16) previously non-responders to standard therapy were(More)
A liquid chromatography-tandem mass spectrometry method is described for the blood determination of selective serotonin reuptake inhibitors (fluoxetine, paroxetine, sertraline, fluvoxamine, and citalopram), serotonin noradrenaline reuptake inhibitors (milnacipram and venlafaxine), a noradrenergic and specific serotoninergic antidepressant (mirtazapine) and(More)
The suicide of a 43-year-old male by intravenous injection of cisatracurium, a non-depolarizing neuromuscular blocking agent, and thiopental, an ultra-short-acting barbiturate, is presented. Systematic toxicological screening by gas chromatography-mass spectrometry (GC-MS), liquid chromatography (LC)-diode-array detection, and LC-MS-MS confirmed the(More)
Our objective was to determine, in a retrospective study of 352 operative hysteroscopies: (a) the rates and the types of complications and (b) the risk factors of peroperative perforations. The most important complications represented 1.7% including two haemorrhage, one symptomatic metabolic abnormalities and three uterine perforations with bowel injuries(More)
The isolated or predominant geodes of the femoral head without signs of coxarthritis or coxitis, seem to form in response to: osteochondritis dissecans in 9 cases where the sequester was only visible in profile films or oblique images for 5 cases, and only at time of operation in 2 cases; incipient necrosis in 3 adult cases, not evidenced in frontal films(More)
Antipsychotic drugs may be associated with arrhythmia, ventricular fibrillation, or torsades de pointes, which can result in sudden death. These drugs could therefore be found in postmortem toxicological analyses of autopsy specimens following unexplained sudden death. The drug concentrations in tissues and body fluids change between the death and(More)
