Highly resistant, extended spectrum β-lactamase (ESBL) producing Enterobacteriaceae in the urine are becoming increasingly common in unexpected patients in the ED.
Individual risk factors associated with the development of severe alcohol withdrawal syndrome (SAWS) included a history of delirium tremens and baseline BP ≥ 140mmHg but no individual symptoms or signs associated with exclusion of SAWS. Composite measures fared better, such as the Prediction of Alcohol Withdrawal Severity Scale; a score ≥ 4 had a LR of 174 (95% CI 43-696).
In the evaluation of older patients with syncope, certain ECG abnormalities increase the risk of 30-day serious cardiac arrhythmias. These ECG abnormalities include non-sinus rhythm; multiple premature ventricular conductions; short PR interval; first degree atrioventricular block; complete left bundle branch block; and ST, T, and Q-wave abnormalities consistent with acute or chronic ischemia.
