A case of chronic intoxication by 2,4-dinitrophenol (2,4-DNP) is reported in a 21-year-old bodybuilder, also known as an abuser of anabolic steroids, who died after ingesting 2 grams of this substance after 6 months of repeated consumption. The bodybuilder presented the triad of symptoms - tachycardia, tachypnoea, profuse sweating - from 6 months before his death, and was hospitalised for multiple organ failure 4 months before his death. Medical staff attributed this serious episode to his consumption of 2,4-DNP.

Protonitazene is a synthetic benzoimidazole opioid of the nitazenes class, developed in the 1950s as an effective analgesic, but never released in the market due to severe side effects and major risk of dependence. The laboratory was involved in the determination of the cause of death for 5 subjects deceased in a French department of the Indian Ocean. The 5 victims were male, aged between 20 and 35 years.

The identification of trimetazidine, a medicine used for treating stable angina pectoris and for preventing angina attacks, has been recently observed in doping cases involving high profile athletes from various countries over the world. In all the files where the authors have been involved, the urine concentration of trimetazidine was low (<2 ng/mL), and the athletes argued that contamination was the source of their adverse analytical finding. It is possible to challenge imposed sanctions in relation to an adverse analytical finding, but it is the responsibility of the athlete to demonstrate he/she is innocent and can qualify for no fault or negligence.

Protonitazene, or N,N-diethyl-5-nitro-2-[(4-propoxyphenyl)methyl]-1H-benzimidazole-1-ethanamine, is a novel synthetic opioid, which belongs to the nitazene family. Over the last four years, nitazenes have re-emerged on the new psychoactive substances market and have been reported in several fatal intoxication cases. The metabolism of several nitazene analogues have already been studied, but to date, no data exists regarding protonitazene.

Protonitazene is a synthetic benzimidazole opioid of the nitazenes class, developed in the 1950s as an effective analgesic, but never released on the market due to severe side effects and possible dependence. Despite its increasing use as a new psychoactive substance starting in 2019, its detection in human hair of intoxicated and deceased consumers has never been reported. We present the development and validation of a specific procedure to identify protonitazene in hair by liquid chromatography with tandem mass spectrometry.

Article Synopsis
  • Kratom (Mitragyna speciosa) is a large tree native to Southeast Asia, with leaves known for their psychoactive and medicinal properties due to active compounds like mitragynine and 7-OH-mitragynine.
  • Over the last decade, kratom's popularity has surged online, leading to an increase in forensic cases related to its consumption.
  • A study analyzed fingernail clippings for kratom alkaloids, identifying high levels of mitragynine, suggesting repetitive use, while 7-OH-mitragynine was not found, indicating that mitragynine remains the key target for testing kratom use, although identifying other alkaloids could improve testing specificity.

  • Analyzing insulin overdose in forensic cases is complex due to insulin's instability and the lack of specific testing methods, leading to many cases being overlooked.
  • A case study of a deceased diabetic man revealed therapeutic levels of insulin lispro, raising questions about potential overdose despite these low concentrations.
  • The study emphasizes the need for comprehensive evaluation of factors such as the deceased's medical history and the conditions surrounding death to correctly interpret postmortem insulin levels.

Analysis of hair collected from putrefied or skeletal bodies is always complex and must take into account several pitfalls, such as external contamination and contamination by biological fluids. This work presents a case of particular complexity. A skeletonized body was discovered on a country road.

Clomiphene is a selective estrogen receptor modulator. It is indicated for the treatment of female infertility issues but in sport, it can be misused to stimulate endogenous testosterone secretion in men. Therefore, it has been prohibited at all times by the World Anti-doping Agency.

2,4-dinitrophenol, initially developed for industrial purposes, is used in the synthesis of dyes and various drugs, including herbicides, fungicides and insecticides. Incidentally, it was discovered that 2,4-dinitrophenol increases human basal metabolic rate. As a consequence, people who want to loose weight can abuse 2,4-dinitrophenol.

Article Synopsis
  • Clomiphene is a medication used to treat female fertility issues by modulating estrogen receptors, but it's banned for athletes because it can indirectly boost testosterone levels.
  • Researchers aimed to create a reliable method to detect clomiphene in hair and nail samples, since its presence hasn't been detected before.
  • They developed a liquid chromatography technique that showed high sensitivity and confirmed the presence of clomiphene in samples from an athlete involved in a doping case.

3-Hydroxyphencyclidine (3-OH-PCP) is a hydroxy derivative of phencyclidine, synthesized in 1978 to investigate the structure-activity relationship of phencyclidine derivates. In vitro studies have shown that 3-OH-PCP, like phencyclidine, acts on the N-methyl-D-aspartate receptor and has a higher affinity for this receptor than phencyclidine. The authors report the case of a 38-year-old man, known for drug addiction, found dead at home with two plastic bags of powders found near his body.

Determining fetal death causes is a complex problem for the forensic pathologist. Beyond the medico-legal context, the expert must be able to evaluate the viability of the fetus at the time of death, to eliminate in-utero fetal death and to determine if the death is related to a fetal, a maternal, a placental cause, or simply related to obstetrical complications. The authors present the case of a 21-year-old woman who unexpectedly gave birth to a fetus during a party.

Fingerprints are invisible traces that result from a deposition of sweat and sebum present on the papillary ridges. As sweat and sebum contain drugs, fingerprints are promising since collection is rapid, non-invasive and difficult to falsify. Very limited data are available in the literature, and therefore, it seems opportune to study the transfer of xenobiotics onto the items taken in hand via the fingerprints.

1-Benzofuran-5-ylpropan-2-amine or 5-APB is a new psychoactive substance (NPS) with empathic effects close to ecstasy (MDMA). Although 5-APB has been observed in fatality cases, the drug has not yet been reported in the context of hidden administration for behaviour impairment, also known as drug-facilitated crime. Such a situation was recently observed on 3 separate occasions in the same dancing club of New Caledonia.

The selective androgen receptor modulators are a recent class of anabolic agents, used to improve athletic performance. Among these molecules, there is (2 S)-N-(4-cyano-3-trifluoromethylphenyl)- 3-(3-fluoro-4-chlorophenoxyl)2-hydroxy-2-methyl-propanamide, commonly known as S-23. This molecule appeared very recently on the doping market.

  • 3-Methoxyphencyclidine (3-MeO-PCP) is a potent new psychoactive substance identified in Europe in 2012, known for its strong binding to NMDA receptors compared to phencyclidine.
  • A case study presented involved a fatal intoxication, revealing significant concentrations of 3-MeO-PCP in both femoral blood (3,525 ng/mL) and urine (7,384 ng/mL), exceeding previously reported fatal ranges.
  • The study identified both known and new metabolites of 3-MeO-PCP in blood and urine, but low ratios of metabolites to the parent drug (<1) suggest that testing for these metabolites is currently not useful for extending the drug's detection

A 43-year-old male, sport coach, presented him-self at the Emergency unit of a local hospital for epigastric pain, myalgia pain and severe headache. He claimed having used for some days a combination of GW1516 (cardarine), a peroxisome proliferator-activated receptor delta agonist (PPAR- δ) and MK2866 (ostarine), a selective androgen receptor modulator (SARM) to gain skeletal muscles. Cytolysis with marked increase of alanine aminotransferase or ALT (up to 922 UI/L) and aspartate aminotransferase or AST (up to 2558 UI/L) and massive rhabdomyolysis with elevated creatine phosphokinase or CPK (up to 86435 UI/L) were the main unusual biochemistry parameters.
