Comparative Study
Emergency department septic shock patient mortality with refractory hypotension vs hyperlactatemia: A retrospective cohort study.
Our objective was to compare in-hospital mortality among emergency department (ED) patients meeting trial-based criteria for septic shock based upon whether presenting with refractory hypotension (systolic blood pressure<90mmHg after 1L intravenous fluid bolus) versus hyperlactatemia (initial lactate≥4mmol/L). ⋯ Hyperlactatemia appears associated with higher in-hospital mortality compared to refractory hypotension among ED patients with septic shock.

Gastrointestinal bleeding is a significant cause of morbidity and mortality worldwide. In addition, it constitutes an important part of health expenditures. In this study, we aimed to determine whether there is a relationship between plasma copeptin levels and the etiology, location and severity of gastrointestinal bleeding. ⋯ We conclude that copeptin cannot be effectively used as a biochemical parameter in an emergency department to determine the etiology and location of gastrointestinal bleeding. It can, however, be used to make decisions on endoscopy and the hospitalization of patients with suspected gastrointestinal bleeding.

Multicenter Study
Clinical and financial implications of emergency department visits for synthetic marijuana.
Many users believe that synthetic cannabinoids offer a safe and legal means of getting high. However, spikes in emergency department visits have been associated with use of synthetic cannabinoids. The purpose of the current study was to document emergency department visits from three large hospitals in one metropolitan area over a two month period. ⋯ This study has three important findings. First, significant ED resources are being used to treat individuals presenting due to effects of synthetic cannabis. Second, synthetic cannabis is not a benign substance. Third, while the hostile and agitated user is generally presented in the media, this study finds significant heterogeneity in presentation. Further research is needed to fully understand the implications of synthetic cannabinoid use.

To retrospectively evaluate the diagnostic performance of qualitative and quantitative radiographic parameters for diagnosing adult acute epiglottitis, and identify the prevalence and risk factors of false-negative neck radiography-based diagnosis of acute epiglottitis. ⋯ EW>6.3mm showed the best diagnostic accuracy, facilitating a neck radiograph-based diagnosis of acute epiglottitis. However, false-negative results on neck radiograph are quite common and previous oral antibiotic usage is a risk factor. Based on the knowledge of the usefulness and risk factors of false-negative results of neck radiography, diagnostic process for acute epiglottitis using neck radiography need to be changed.
