A 24-year-old man whose medical history was significant for alcohol abuse and depression was found unresponsive in bed. He had several prior suicide attempts with 'pills' and had also been hospitalized for an accidental overdose on a previous occasion. Autopsy findings were unremarkable apart from pulmonary edema and congestion, and urinary retention. Postmortem peripheral blood initially screened positive for mitragynine 'Kratom' (by routine alkaline drug screen by gas chromatography-mass spectrometry, GC-MS), which was subsequently confirmed by a specific GC-MS selective ion mode analysis following solid-phase extraction. Concentrations were determined in the peripheral blood (0.23 mg/L), central blood (0.19 mg/L), liver (0.43 mg/kg), vitreous (<0.05 mg/L), urine (0.37 mg/L) and was not detected in the gastric. Therapeutic concentrations of venlafaxine, diphenhydramine and mirtazapine were also detected together with a negligible ethanol of 0.02% (w/v). The results are discussed in relation to previous cases of toxicity, and the lack of potential for mitragynine postmortem redistribution.
In this case report, we present an evaluation of the distribution of postmortem concentrations of acetyl fentanyl in a fatality attributed to the drug. A young man who had a history of heroin abuse was found deceased at his parents' home. Toxicology testing, which initially screened positive for fentanyl by ELISA, subsequently confirmed acetyl fentanyl by gas chromatography-mass spectrometry specific ion monitoring (GC-MS SIM) analysis following liquid-liquid extraction. No other drugs or medications, including fentanyl, were detected. The acetyl fentanyl peripheral blood concentration was quantified at 260 ng/mL compared with the central blood concentration of 250 ng/mL. The liver concentration was 1,000 ng/kg, the vitreous was 240 ng/mL and the urine was 2,600 ng/mL. The cause of death was certified due to acute acetyl fentanyl intoxication, and the manner of death was certified as an accident.
In this case report, we present an evaluation of the distribution of postmortem concentrations of butyr-fentanyl in a fatality attributed principally to the drug. A man who had a history of intravenous drug abuse was found unresponsive on the bathroom floor of his home. Drug paraphernalia was located on the bathroom counter. Toxicology testing, which initially screened positive for fentanyl by enzyme-linked immunosorbent assay, subsequently confirmed butyr-fentanyl, which was then quantitated by gas chromatography-mass spectrometry-specific ion monitoring (GC-MS SIM) analysis following liquid-liquid extraction. The butyr-fentanyl peripheral blood concentration was quantitated at 58 ng/mL compared with the central blood concentration of 97 ng/mL. The liver concentration was 320 ng/g, the vitreous was 40 ng/mL, the urine was 670 ng/mL and the gastric contained 170 mg. Acetyl-fentanyl was also detected in all biological specimens tested. Peripheral blood concentration was quantitated at 38 ng/mL compared with the central blood concentration of 32 ng/mL. The liver concentration was 110 ng/g, the vitreous was 38 ng/mL, the urine was 540 ng/mL and the gastric contained <70 mg. The only other drug detected was a relatively low concentration of benzoylecgonine. The cause of death was certified as acute butyr-fentanyl, acetyl-fentanyl and cocaine intoxication, and the manner of death was certified as accident.
In this case report, we present an evaluation of postmortem concentration distribution of the hallucinogenic compound 4-methoxyphencyclidine (4-MeO-PCP) in a fatality principally attributed to this drug. Another hallucinogen, 4-hydroxy-N-methyl-N-ethyltryptamine was also detected, but was not quantitated. A man--who had a history of recent 'strange' behavior--was found deceased, on his bed, in his locked room. Toxicology testing, which initially screened positive for phencyclidine (PCP) by ELISA, subsequently detected and confirmed the two hallucinogens by gas chromatography-mass spectrometry. 4-MeO-PCP concentrations were then quantified by a specific secondary testing technique. The peripheral blood concentration was 8.2 mg/L compared with the central blood concentration of 14 mg/L. The liver concentration was 120 mg/kg, the vitreous was 5.1 mg/L, the urine was 140 mg/L and the gastric contents contained 280 mg. PCP was not detected, but therapeutic concentrations of venlafaxine, olanzapine, lorazepam and hydroxyzine were confirmed. The cause of death was certified due to acute mixed drug intoxication, and the manner of death was certified as accident.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
