Hydroxocobalamin, a precursor molecule to vitamin B12, has emerged as the preferred empiric treatment for patients rescued from enclosed-space fires with concern for inhalational injury and potential concomitant cyanide toxicity. Limited data exist on the effects of hydroxocobalamin toxicity, particularly in pediatric patients. ⋯ We believe this to be the first reported case of iatrogenic pediatric hydroxocobalamin overdose for the treatment of suspected cyanide toxicity. Erythroderma and chromaturia are expected side effects of hydroxocobalamin, even at therapeutic levels. Along with minor airway burns, the only other finding was a transient and hemodynamically neutral bradycardia, which began shortly after prehospital intubation. As this bradycardia occurred prior to hydroxocobalamin administration, more likely culprits include vagal nerve stimulation from direct laryngoscopy, and sinoatrial muscarinic receptor stimulation caused by repeated doses of succinylcholine. In all, we were unable to appreciate any complications due to excess hydroxocobalamin administration.

The perforation of the gallbladder (GP) is one of the most significant complications of acute cholecystitis. A biochemical marker indicating the GP has not been determined fully to date. Pentraxin 3 and pro-adrenomedullin (Pro-ADM) proteins are novel acute phase reactants. We aimed to investigate the relationship between serum Pentraxin 3 and Pro-ADM and the GP in patients with acute cholecystitis. ⋯ Our study results reveal that serum Pentraxin 3 and pro-ADM may be novel biochemical parameters in the detection of GP in acute cholecystitis cases.

Bug off! Severe toxicity following inhalational exposure to N, N-diethyl-meta-toluamide (DEET).
N, N-diethyl-meta-toluamide (DEET) is an insect repellent currently used by millions of people since 1956. DEET has an excellent safety profile and has remarkable protection against mosquitoes, ticks and various other arthropods. Toxicity is unusual, and is generally associated with incorrect, or overuse of the product. We report a patient with severe toxicity following inhalational exposure to a "bug bomb". containing 98% DEET.

Postintubation hypotension (PIH) is an adverse event associated with poor outcomes in emergency department (ED) endotracheal intubation. This study aimed to evaluate the association between sedative dose adjustment and PIH during emergency airway management. We also investigated the impact of patient and procedural factors on the incidence of PIH. ⋯ PIH was mainly related to predisposing patient-related factors. Only adjustment of etomidate dose was associated with the incidence of PIH.
