New psychoactive substance cocktail in an intensive care intoxication case elucidated by molecular networking.

Clinical toxicology (Philadelphia, Pa.) January 1, 2022 Romain Pelletier, Brendan Le Daré, Loic Grandin et al. 22 citations

A 37-year-old man with a history of drug abuse was found unconscious with bags of powder labeled as research chemicals and traces of powder on his nose. He was rehydrated, intubated, and admitted to the intensive care unit. Urine analysis identified several new psychoactive substances, including high concentrations of 3-OH-PCP (12,085 mg/L) and 3-MeO-PCP (1,100 mg/L), along with 2F-DCK, N-ethylhexedrone, and CMC. Molecular networking, a bioinformatic approach, confirmed that the powders in the bags matched the substances found in the patient's urine. This case demonstrates how molecular networking can aid in sample comparison, target quantification methods, and support treatment decisions for intoxications involving arylcyclohexylamine compounds.

Magic truffle intoxication: A case report

Emergency Care Journal June 27, 2022 Brendan Le Daré, Romain Pelletier, Aurélien Couette et al. 1 citation

A 20-year-old man arrived at an emergency department in a state of euphoria, disorientation, intense visual hallucinations, episodic amnesia, and agitation requiring physical restraint after consuming an unusual form of hallucinogenic mushroom. The patient's family brought intact specimens, but no health professional could identify them. Toxicological screening detected psilocin in both the patient's urine and the mushrooms, guiding identification toward the Psilocybes genus. Ten hours after ingestion, the patient was discharged asymptomatic. Recognizing unusual forms of hallucinogenic mushrooms may help emergency physicians improve diagnosis and management, especially since hallucinogenic substances are not routinely tested in toxicological analyses.
