Introduction: One of the most appropriate methods for needs assessment is to assess learners' needs and arrange the educational programs based on their viewpoints. The aim of this study was to determine the topics and content of Continuing Medical Education (CME) programs in five selected subjects by medical education experts and target group, based on the real needs of General Practitioners (G...
Immunoassays are useful laboratory methods for clinical and forensic toxicology diagnostics. The methods are fast, sensitive, accurate and let determine poisons concentrations in different kinds of biological fluids. There are blood and urine or alternative: saliva, sweat and hair. The choice of the sample depends on the purpose of analysis. In acute poisoning the blood or serum poison concentr...
Background: Postmortem redistribution (PMR) refers to the changes that may occur in drug concentrations after death. Consequently, postmortem concentrations in blood may not always replicate the antemortem drug levels. Literature supports the model describing drugs with a liver (L) concentration to peripheral blood (P) concentration ratio less than 5 (L/kg) being prone to little or no PMR. Conv...
Introduction This study compared beta-blockers reported by pilots with the medications found by postmortem toxicology analysis of specimens received from fatal aviation accidents between 1999 and 2015. Several studies have compared drugs using the standard approach: Compare the drug found by toxicology analysis with the drug reported by the pilot. This study uniquely examined first the pilot-re...
Liquid chromatography-mass spectrometry has evolved from a topic of mainly research interest into a routinely usable tool in various application fields. With the advent of new ionization approaches, especially atmospheric pressure, the technique has established itself firmly in many areas of research. Although many applications prove that LC-MS is a valuable complementary analytical tool to GC-...
We developed a test that compares sequential measurements of a biomarker against previous readings performed on the same individual. A probability mass function expresses prior information on interindividual variations of intraindividual parameters. Then, the model progressively integrates new readings to more accurately quantify the characteristics of the individual. This Bayesian framework ge...
The identification of general unknown poisons in complex biological materials like postmortem blood and tissue is a great challenge for the forensic toxicologist. Therefore, a screening procedure utilizing a semi-automatic work-up with an ASPEC system was developed. A broad range of different compounds can be isolated by using non-selective and generally applicable organic polymeric sorbents su...
