Concentrations of phencyclidine in blood and liver are presented in five fatal cases occurring in Los Angeles County in 1976. Eleven other deaths in which phencyclidine contributed to death are described; acute psychotic reactions were observed in some of these cases. Two cases involved the drowning of individuals whose swimming capabilities may have been diminished from the effects of PCP. One case is presented in which a 20-year-old male took a massive overdose of phencyclidine for suicidal purposes.

Center for Health Optimization and Implementation Research, VA Boston Healthcare System and VA Bedford Healthcare System, Boston and Bedford, MA, USA.
Background: Deprescribing, intentional medication discontinuation or dose reduction, can reduce potentially inappropriate medication use and medication-related harms. Engaging patients in deprescribing discussions may increase likelihood of deprescribing and promote shared decision-making.
Objective: To examine the impact of patient-directed educational brochures on patient engagement and deprescribing discussions with primary care providers (PCPs).

Quasiperiodic fluctuations with frequency are observed in a variety of responses that either originate from or strongly depend on the cochlea's active mechanics. These spectral microstructures are unique and stable features of individual ears and have been most thoroughly studied in behavioral hearing thresholds and otoacoustic emissions (OAEs). While the exact morphology of the microstructure patterns may differ across measurement types, the patterns are interrelated and are thought to depend on common mechanisms.

January 2025
Tecnológico de Monterrey, Escuela de Medicina y Ciencias de la Salud, Monterrey, Nuevo León, México.
Background: Minimally invasive pancreatoduodenectomy has gained widespread acceptance among hepatopancreatobiliary surgeons due to its demonstrated advantages in perioperative outcomes compared to the conventional open approach. This meta-analysis, along with trial sequential analysis, aimed to compare the outcomes of robotic pancreatoduodenectomy and laparoscopic pancreatoduodenectomy based on the current available evidence.
Methods: A systematic search of PubMed, Cochrane, Scopus, and Web of Science was conducted from inception to July 2024.
