RESUMO

Novel synthetic opioids contribute considerably to the opioid epidemic, especially with the frequent emergence of structurally similar compounds. This case report describes a fatal intoxication involving 2-methyl AP-237. A 54-year-old Caucasian male was found deceased from an apparent drug overdose. A plastic container labeled "2MAP" and a cut straw were found in the decedent's backpack at the scene. A white substance found in the container tested positive for fentanyl by field testing. According to his medical history, the decedent was treated for a drug overdose 3 years prior to his death. With no diagnostic findings at autopsy, the case was submitted for toxicological analysis. An unknown substance was detected in peripheral blood and urine using gas chromatography with nitrogen phosphorous detection (GC-NPD). Further testing was conducted using gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-quadrupole-time-of-flight mass spectrometry (LC-QTOF-MS) which confirmed the presence of 2-methyl AP-237 and potential metabolites in blood and urine. Quantitation by GC-NPD revealed concentrations of 2-methyl AP-237 in blood and urine at 480 ng/mL and 4200 ng/mL, respectively. The toxicological analysis also identified and quantitated alprazolam in the blood at 55 ng/mL. Additionally, the metabolism of 2-methyl AP-237 was investigated and three hydroxylated metabolites were identified in peripheral blood and urine. Limited literature is available for the detection and quantitation of 2-methyl AP-237 in postmortem specimens. Given the toxicological findings with unremarkable autopsy findings, this case is an example of a fatal intoxication involving 2-methyl AP-237.

RESUMO

Increased prevalence of illicitly manufactured fentanyl and fentanyl analogs has contributed substantially to overdose deaths in the United States (1-3). On October 26, 2015, CDC issued a Health Advisory regarding rapid increases in deaths involving fentanyl. This CDC Health Advisory has been updated twice to address increases in fentanyl and fentanyl analog overdoses and their co-occurrence with nonopioids (4). Deaths involving carfentanil, an analog reportedly 10,000 times more potent than morphine and 100 times more potent than fentanyl, were first reported in Florida, Michigan, and Ohio in 2016 and described in an August 2016 CDC Health Advisory (1,5). Carfentanil is used to rapidly immobilize large animals in veterinary medicine and has no U.S. approved therapeutic use in humans. Carfentanil's street price per dose is likely lower than that of heroin. During 2016 and 2017, an outbreak of carfentanil-involved fatal overdoses in Florida emerged, and the Medical Examiner jurisdiction serving Sarasota, Manatee, and DeSoto counties (the Sarasota area) was the outbreak epicenter. This report describes toxicology profiles, sociodemographic information, and geographic distributions of carfentanil-involved fatal overdoses (carfentanil deaths) in the Sarasota area compared with those in the rest of Florida (i.e., all Florida counties excluding Sarasota area) from January 2016 to December 2017. The Sarasota area accounted for 19.0% of 1,181 statewide carfentanil deaths that occurred during this time and experienced a peak in carfentanil deaths preceding the larger Florida outbreak. The report of a single carfentanil death from August to December 2017 (compared with 73 reported deaths during the same period in 2016) appeared to mark the end of the outbreak in the area. The threat of such rapid, intense fatal overdose outbreaks highlights the need for accelerated reporting, reliable data sharing systems, and novel proactive surveillance to support targeted prevention and response efforts by public health and safety organizations (6).

RESUMO

Fentanyl induces pharmacological effects and abuse liability comparable to other prescription opioids and heroin. A surge in fentanyl-related fatalities has been periodically reported throughout the USA. The University of Florida Forensic Toxicology Laboratory observed a significant increase in fentanyl-related deaths starting in mid-2014. The present report evaluated toxicological findings, demographics of the decedents and circumstances of death in the postmortem cases that were submitted to the laboratory for toxicological analysis from July 2014 to January 2015 and that were tested for fentanyl in biological specimens. The cases originated from 6 of the 24 Florida Medical Examiner Districts, with the majority from District 12 (Desoto, Manatee and Sarasota counties). The specimens were analyzed for fentanyl by gas chromatography-mass spectrometry; the limit of detection (LOD) was 0.62 ng/mL and the limit of quantification (LOQ) was 2.5 ng/mL. During the 7-month period, the laboratory tested 143 postmortem cases for fentanyl and 50% had quantifiable fentanyl in postmortem blood. Fentanyl concentrations ranged from 2.5 to 68 ng/mL (n = 66; median: 9.8 ng/mL); six cases were positive for fentanyl >LOD but

RESUMO

Because death from suffocation in traffic fatalities has not been well described, we delineated the clinical, circumstantial, and autopsy findings associated with suffocation in a series of motor vehicle crashes. Medical examiner case files from a 5-year period were reviewed. Scene investigation, autopsy, toxicology, and first-responder reports were examined. Crash descriptions were reviewed, including vehicle type, mechanism of crash, response time, restraint use, occupant ejection, and victim position in cabins of vehicles. Mechanisms of suffocation, including torso compression, inversion, neck flexion, facial occlusion, and blood aspiration, were determined for each case. The files were searched for factors relevant to the diagnosis of suffocation, namely, cerebral concussion, alcohol intoxication, obesity, petechiae, lung weights as a proxy for livor, natural disease, and impact wounds. Twenty-nine traffic fatality cases were identified in which suffocation caused death. In 26, suffocation mechanisms were solely responsible for death. In 3, death was caused by suffocation in combination with other mechanisms. Twenty-five subjects were occupants of vehicles with cabins and 4 were motorcycle riders. The most common mechanism of suffocation was torso compression. Most subjects had either multiple mechanisms of suffocation or a single mechanism acting in concert with concussion or alcohol intoxication. Concussion and intoxication were common, with one or both present in 20 subjects, including all of those with blood aspiration. Petechiae were frequent but were found consistently only among those with inversion. Cutaneous chest petechiae were associated with inversion and torso compression. Lung weights were highest among those with blood aspiration and lowest among those with inversion. Body mass index was highest among those with inversion, suggesting that obesity could be a risk factor for this mechanism.
