Case Reports1,4-Butanediol overdose mimicking toxic alcohol exposure.
Context: 1,4-butanediol (1,4-BD) is a gamma-hydroxybutyrate (GHB) analogue with a similarly narrow therapeutic window that is becoming a more common cause of recreational overdose. Reports of confirmed exposures are limited. Case details: A 44 year-old man who had consumed alcohol subsequently became unconscious after ingesting what was thought to be GHB. ⋯ In overdose, 1,4-BD can induce a HAGMA and other features of toxic alcohol poisoning. Managing an unconscious patient with these features can prompt certain treatments until the diagnosis is refined, which can require specific laboratory testing to identify the culprit. The actual risk of toxic alcohol and other causes is adjusted on a case-by-case basis from the history of exposure and local epidemiology of substance use and poisoning.

Cottonmouth snake bites reported to the ToxIC North American snakebite registry 2013-2017.
Introduction: The majority of venomous snake exposures in the United States are due to snakes from the subfamily Crotalinae (pit vipers). There are three types of US pit vipers: rattlesnakes (Crotalus and Sisturus spp.) copperheads (Agkistrodon contortrix), and cottonmouths (Agkistrodon piscivorus) also known as water moccasins. Cottonmouth bites are reported less frequently than other pit viper envenomations, and data on cottonmouth envenomation are limited. ⋯ Conclusions: Cottonmouth envenomations are relatively infrequent. However, they can cause significant local and systemic toxicity. Most cottonmouth envenomations in this series were treated with antivenom and were hospitalized beyond 24 hours.
