<b><i>Background/Aims:</i></b> Increasing rates of overdose deaths involving opioid maintenance treatment (OMT) medications and particularly methadone have been observed concurrently with the implementation liberal OMT strategies (i.e. minimum control high doses prescribed). This study examined methadone-related in a programme. <b><i>Methods:</i></b> Drug-overdose (n = 130) detection Copenhagen, Aarhus, Odense Municipality, Denmark, during...

Sudden death due to acute intoxication occurs frequently in patients with opioid addiction (OA). To examine whether certain genotypes were associated this, we examined the frequencies of 29 SNPs located candidate genes related pharmacology: ABCB1, OPRM1, UGT2B7, CYP3A5, CYP2B6, CYP2C19, CYP2D6, COMT, KCNJ6 and SCN9A 274 deceased OA (DOA), 309 living (LOA) 394 healthy volunteers (HV). The main hypothesis study was that subjects homozygous for variant 3435T ABCB1 (rs1045642) occur more DOA...

Abstract Patients suffering from psychiatric disorders have an excess mortality and a shorter life span expectancy compared to the general population. Furthermore, they are treated with multiple drugs known increased risk of drug abuse. In this study, we aimed at investigating pharmaceutical abuse profiles deceased included in Danish prospective autopsy‐based forensic study on patients, SURVIVE. Using postmortem systematic toxicological analysis results, identified 129 different consumed...

Intracranial pressure (ICP) monitoring at our department includes a standardized postural change examination to evaluate its effects on ICP. During these procedures we observed that neck flexion caused an increase in ICP one patient. To clarify if the observation was random occurrence or it could be reproduced, added and extension standard examination.

An analytical procedure is presented which determines benzene, toluene, ethylbenzene and total aromatics in non-olefinic hydrocarbon solvents boil between 100 450°F. This compositional information required connection with current air pollution laws. The method based on (a) the addition of a known amount internal standard (hexamethylbenzene), (b) segregation aromatic hydrocarbons sample by liquid chromatography silica, (c) analysis this fraction (plus solvent) gas chromatography. applicable...
