Previous work has shown poisoning-related emergency department (ED) visits are increasing, and these visits are resource-intensive. Little is known, however, about how resource utilization for patients with known or suspected poisoning differs from that of general ED patients. ⋯ ED patients with known or suspected poisoning are more resource intensive than general ED patients. These results may have implications for both resource allocation (particularly for departments that might see a high volume of such patients) and ED operations management.

Scorpion envenomation is potentially life-threatening and affects children in the Southwestern USA. An FDA-approved antivenom is available, but its high cost has led to use of off-label antivenom dosing or supportive care alone as alternatives to FDA-recommended dosing. This study sought to determine whether treatment approach influences outcomes in envenomated children. ⋯ In this study, clinical presentation appeared to influence treatment. Groups that received antivenom had a higher envenomation grade than the group that received supportive care. The FDA-recommended dosing group was younger and had more respiratory distress than those treated with initial doses of 1-2 vials. Outcomes were not significantly different between groups. Prospective studies may identify the ideal population for each treatment approach.

Review Meta Analysis
Cannabinoid Hyperemesis Syndrome: Diagnosis, Pathophysiology, and Treatment-a Systematic Review.
Cannabinoid hyperemesis syndrome (CHS) is a syndrome of cyclic vomiting associated with cannabis use. Our objective is to summarize the available evidence on CHS diagnosis, pathophysiology, and treatment. We performed a systematic review using MEDLINE, Ovid MEDLINE, Embase, Web of Science, and the Cochrane Library from January 2000 through September 24, 2015. ⋯ CHS is a cyclic vomiting syndrome, preceded by daily to weekly cannabis use, usually accompanied by symptom improvement with hot bathing, and resolution with cessation of cannabis. The pathophysiology underlying CHS is unclear. Cannabis cessation appears to be the best treatment.

Electronic nicotine delivery systems (ENDS, often called e-cigarettes) are nicotine delivery devices that heat nicotine into vapour that is inhaled, a process called 'vaping'. Use eclipsed nicotine-replacement therapy (NRT) in 2014 but ENDS role in smoking cessation remains controversial. Safety has not been proven and there have been reports to US poison centres regarding potential ENDS-related nicotine toxicity. A further concern is use of ENDS to vape recreational drugs, but there is limited data to substantiate this. The aim of this study was to report on ENDS use to vape recreational drugs in patrons of a South London nightclub where high prevalence of recreational drug use has previously been shown. ⋯ 5.9 % of individuals in this sample reported using ENDS to vape substances other than nicotine. Further work is required in larger populations to determine how common this is, evaluate which agents are being vaped and to inform appropriate public education.

Comparative Study
Clinical Effects of Synthetic Cannabinoid Receptor Agonists Compared with Marijuana in Emergency Department Patients with Acute Drug Overdose.
Synthetic cannabinoid receptor agonists (SCRAs) are heterogeneous compounds originally intended as probes of the endogenous cannabinoid system or as potential therapeutic agents. We assessed the clinical toxicity associated with recent SCRA use in a large cohort of drug overdose patients. ⋯ In the first clinical study comparing the adverse effects of SCRA overdose vs. marijuana controls in an ED population, we found that SCRA overdoses had significantly pronounced neurotoxicity and cardiotoxicity compared with marijuana.
