The use of 3,4-methylenedioxymethamphetamine (MDMA) in drug-facilitated sexual assault (DFSA) is not uncommon. Indeed, the effects associated with the use of this substance may lead to disinhibition. Several synthetic cathinones, such as mephedrone or methylone, also possess marked entactogenic properties. This manuscript aims to (i) report a DFSA case involving a novel cathinone derivative, namely N-ethyl-pentedrone (NEPD) and (ii) review previously reported DFSA cases involving synthetic cathinones. Using liquid chromatography-high-resolution mass spectrometry (LC-HRMS), NEPD was detected in both plasma and urine collected from a 36-year-old male who had been victim of DFSA. Furthermore, an exhaustive, non-period-specific English-language literature search was performed using several different electronic databases to identify DFSA cases involving synthetic cathinones. Overall, five synthetic cathinones have been associated with DFSA:methylenedioxypyrovalerone, 4-methylethcathinone, α -pyrrolidinopentiophenone, mephedrone, α -pyrrolidinohexiophenone, and methylone, which appears to be the most frequently reported. Methylone is the β-keto analog of MDMA, with which it shares substantial pharmacological similarities. Indeed, the pharmacological effects of methylone are similar to those associated with MDMA. By contrast, little is known regarding NEPD's pharmacological effects in humans. Based on subjective reports, NEPD can produce both positive and negative effects in human. Unlike what is reported in the case of methylone or mephedrone, only a small minority of NEPD users report slightly entactogenics effects. Such properties theoretically make NEPD more suitable for use in a chemsex context than in DFSA context; even though, the boundary between these two specific forms of sexualized drug use can sometimes appear tenuous.

Pharmacobezoars develop after an acute overdose or during routine drug administration. Here, the authors present a case of fatal multidrug overdose involving a 62-year-old woman. Her usual treatment included tramadol extended-release, citalopram, and mirtazapine. Furthermore, she self-medicated and misused her husband's medications. The autopsy revealed the presence of a voluminous medication bezoar in the stomach. No mechanical complication was noted. Toxicologic analyses were performed using gas chromatography with flame ionization detection, liquid chromatography with diode array detection, gas chromatography with mass spectrometry detection, and liquid chromatography coupled to tandem mass spectrometry. Tramadol (34,000 mcg/L), O-desmethyltramadol (2200 mcg/L), propranolol (6000 mcg/L), bromazepam (2500 mcg/L), zopiclone (1200 mcg/L), and citalopram (700 mcg/L) were identified in femoral blood at toxic concentrations. Interestingly, the femoral blood and vitreous humor concentration ratio was approximately 0.7. Furthermore, an English exhaustive literature search was performed using several different electronic databases without any limiting period to identify published pharmacobezoar-related fatalities. Seventeen publications were identified reporting a total of 19 cases. Decedents' mean age was 47.6 years [0.8–79] and a clear female predominance emerged. Several drugs were involved in pharmacobezoar formation. Death was attributed to drug toxicity in 13 cases, and to mechanical complications and/or sepsis in 4 cases. A mixed cause of death was reported in 2 cases. Although rare, pharmacobezoars remain potentially lethal and raise challenges in therapeutic management.
