It is important to predict which patients may require renal replacement therapy (RRT) at the time of initial presentation after crush injuries. There is limited data in the literature examining the predictors of RRT. ⋯ The dialysis score predicts the need for RRT quite well. The simplicity of use and high sensitivity and specificity of this score in earthquake-related crush injuries will greatly facilitate clinicians in patient triage and follow-up.

Rattlesnake envenomations account for many of the Crotalid envenomations in the United States annually. Two antivenoms are currently available to treat Crotalid envenomation in this country: Crotalidae-polyvalent ovine immune Fab antivenom (CroFab®; FabAV) and Crotalidae equine immune F(ab')₂ antivenom (ANAVIP®; F(ab')₂AV). Few studies have compared the adverse effect rates for each. ⋯ Five patients (1.5 %) had severe adverse events reported in the poison center records following FabAV administration, and none were reported following F(ab')₂AV administration (p = 0.025). Overall, our poison center data suggests the rate of adverse events is low following the use of either antivenom. Our findings are limited by the lack of consistent timing data, a smaller F(ab')₂AV cohort, retrospective format, and use of poison center data.

Unintentional plant ingestions and poisoning are common. Generally, these ingestions are asymptomatic or minimally symptomatic. Increased toxicity is often associated with the foraging for plants incorrectly identified as edible plants. We present a case series of seven family members poisoned by suspected Death Camas, also known as Meadow Death Camas, (Toxicoscordion venenosum), when the plant was misidentified as edible while foraging for Wild Onion (Allium canadense). ⋯ Five children and two adults presented to the emergency department after eating bulbs of suspected Death Camas (Toxicoscordion venenosum). Symptoms began within 30 to 60 min including nausea, vomiting, and abdominal pain. This was followed by bradycardia and hypotension consistent with Death Camas poisoning from alpha blockade, sodium channel activation, and increased vagal activity from the toxins. All of the patients required admission to the intensive care unit. Six patients were treated with supportive care alone and two patients required vasopressor support. An 89-year-old female developed a wide complex tachycardia and was treated with amiodarone. All patients had resolution of toxicity within 24 h and were discharged to home. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Foodborne illness is a common presentation highlighted by signs and symptoms manifesting in multiple people eating the same meal. The misidentification of toxic plants as edible is associated with acute onset of signs and symptoms of toxicity. The toxins associated with Death Camas (Toxicoscordion venenosum), commonly thought to be edible Wild Onion (Allium canadense), are unique as these can cause gastrointestinal effects (e.g., nausea, vomiting, diarrhea), and cardiovascular effects (e.g., bradycardia, hypotension), which are often refractory to supportive therapy alone (e.g., crystalloid fluids), and can require atropine and vasopressors.
