Pulmonary embolism (PE) is a common emergency department (ED) diagnosis with a wide range in mortality rates. Methods to identify and risk-stratify PE, including measuring right ventricular strain (RVS) by echocardiography (echo), are essential in providing effective and efficient care. A limited echo examination aims to expedite and increase availability of RVS determination through assessment at the bedside by the ED provider. ⋯ In this retrospective cohort study, limited echo demonstrated moderate agreement with consultative echo for RVd. Right ventricular dilation on limited echo was highly specific for RVS but had low sensitivity.

Glyphosate-surfactant herbicide is promoted by the manufacturer as having no risks to human health. Glyphosate surfactant has recently been used with increasing frequency in suicide attempts, so clinical toxicologists occasionally encounter cases of severe systemic toxicity. The purpose of this study was to identify the early predictive factors of patients at risk for mortality and the usefulness of the corrected QT interval (QTc interval) for predicting mortality from glyphosate-surfactant intoxication. ⋯ Prolonged QTc interval seems to be a useful prognostic factor for mortality in patients intoxicated with glyphosate-surfactant herbicide.
