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.

Review Practice GuidelineMethodology for AACT evidence-based recommendations on the use of intravenous lipid emulsion therapy in poisoning.
Intravenous lipid emulsion (ILE) therapy is a novel treatment that was discovered in the last decade. Despite unclear understanding of its mechanisms of action, numerous and diverse publications attested to its clinical use. However, current evidence supporting its use is unclear and recommendations are inconsistent. ⋯ The evidence will be appraised using the GRADE system. A thorough and transparent process for consensus statements will be performed to provide recommendations, using a modified Delphi method with two rounds of voting. This process will allow for the production of useful practice recommendations for this therapy.

ReviewScorpion-related cardiomyopathy: Clinical characteristics, pathophysiology, and treatment.
Scorpion envenomation is a threat to more than 2 billion people worldwide with an annual sting number exceeding one million. Acute heart failure presenting as cardiogenic shock or pulmonary edema, or both is the most severe presentation of scorpion envenomation accounting for 0.27% lethality rate. ⋯ Scorpion cardiomyopathy is characterized by a marked and reversible alteration in biventricular performance. Supportive treatment relying on ventilatory support and dobutamine infusion is a bridge toward recovery in the majority of patients.
