The aim of this study was to investigate the usefulness of postmortem biochemical investigations in the diagnosis of fatal hypothermia. 10 cases of fatal hypothermia and 30 control cases were selected. A series of biochemical parameters, such as glucose, acetone, 3-beta-hydroxybutyrate, isopropyl alcohol, free fatty acids, adrenaline, growth hormone,(More)
AIM This study aims to investigate the clinical and demographic factors influencing gentamicin pharmacokinetics in a large cohort of unselected premature and term newborns and to evaluate optimal regimens in this population. METHODS All gentamicin concentration data, along with clinical and demographic characteristics, were retrieved from medical charts(More)
The concentrations of 3-beta-hydroxybutyrate (3HB) in femoral blood, urine, vitreous humor as well as pericardial and cerebrospinal fluids were retrospectively examined in a series of medico-legal autopsies, which included cases of diabetic ketoacidosis, hypothermia fatalities without ethanol in blood, bodies presenting mild decompositional changes, and(More)
According to the hypothesis of Traub, also known as the 'formula of Traub', postmortem values of glucose and lactate found in the cerebrospinal fluid or vitreous humor are considered indicators of antemortem blood glucose levels. However, because the lactate concentration increases in the vitreous and cerebrospinal fluid after death, some authors postulated(More)
When requesting a blood level measurement in the context of "Therapeutic drug monitoring" (TDM), numerous aspects have to be considered in the pre-analytical and analytical area, as in the integration of associated clinical data. This review presents therapeutic classes for which a clinical benefit of TDM is established or suggested, at least in some(More)
Requesting a blood level measurement of a drug is part of the global approach known as "Therapeutic Drug Monitoring". Diverse situations require this monitoring approach, such as inadequate response to treatment or organ failure. Every drug however does not possess all the characteristics for a TDM program. The therapeutic range of a TDM drug has indeed to(More)
The discrepancy of results for the quantification of androstenedione in human serum between a radioimmunoassay (RIA) method and high performance liquid chromatography tandem-mass spectrometry (LC-MS/MS) was investigated. RIA overestimated concentrations compared to LC-MS/MS on 59 clinical samples (RIA=1.79×LC-MS/MS+0.94). RIA kit and LC-MS/MS calibrants(More)
Isopropyl alcohol (IPA) is widely used as an industrial solvent and cleaning fluid. After ingestion or absorption, IPA is converted into acetone by alcohol dehydrogenase. However, in ketosis, acetone can be reduced to IPA. The aim of this study was to investigate blood IPA and acetone concentrations in a series of 400 medico-legal autopsies, including cases(More)
Insulin determination in blood sampled during post-mortem investigation has been repeatedly asserted as being of little diagnostic value due to the rapid occurrence of decompositional changes and blood haemolysis. In this study, we assessed the feasibility of insulin determination in post-mortem serum, vitreous humour, bile, and cerebrospinal and(More)
Carnitine plasma concentrations were determined by an enzymatic radioisotopic method in 353 metabolically healthy children and in 41 adults. There was a positive correlation between total and free carnitine plasma concentrations and the age of the children. Both free and acylcarnitine concentrations were elevated on the 1st day of life, reflecting an(More)
