Observational StudyPhencyclidine analog use in Sweden--intoxication cases involving 3-MeO-PCP and 4-MeO-PCP from the STRIDA project.
3-Methoxy-phencyclidine (3-MeO-PCP) and 4-methoxy-phencyclidine (4-MeO-PCP) are analogs of and drug substitutes for the dissociative substance PCP ("Angel dust"), a recreational drug that was most popular in the 1970s. In Sweden, use of methoxylated PCP analogs was noted starting in mid-2013, according to statistics from the Poisons Information Centre. The objective of this case series was to present clinical and bioanalytical data from analytically confirmed non-fatal intoxications associated with 3-MeO-PCP and/or 4-MeO-PCP within the STRIDA project. ⋯ Laboratory analysis constitutes an important basis for the assessment of NPS hazard and availability. The adverse effects noted in cases of acute intoxications involving 3- and/or 4-MeO-PCP resembled those of other dissociatives such as PCP, ketamine, and methoxetamine. However, similar to intoxications involving other NPS, poly-substance use was found to be common.

Observational StudyA descriptive analysis of aspartate and alanine aminotransferase rise and fall following acetaminophen overdose.
Risk prediction following acetaminophen (paracetamol, APAP) overdose is based on serum APAP, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels. One recently proposed risk stratification tool, the APAPxAT multiplication product, uses either AST or ALT, whichever is higher, yet their interrelation is not well known following APAP-induced hepatic injury. ⋯ Either AST or ALT can be used for early risk stratification tools when only one is known. Any criterion for N-AC discontinuation should be based on the decline of AST rather than ALT, with a potential benefit measured in days.
