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.

Hematuria by urine dipstick with absent red blood cells (RBCs) on microscopy is indicative of rhabdomyolysis. We determined the sensitivity of this classic urinalysis (UA) finding in the diagnosis of rhabdomyolysis. ⋯ The combination of a positive urine dip for blood and negative microscopy is an insensitive test for rhabdomyolysis, and the absence of this finding should not be used to exclude the diagnosis.

Finger counting: an alternative method for estimating pediatric weights.
We compared the accuracy of a conceptually simple pediatric weight estimation technique, the finger counting method, with other commonly used methods. ⋯ The finger counting method is an acceptable alternative to the Broselow method for weight estimation in children aged 1 to 9 years. It outperforms the traditional APLS method but underestimates weights compared with parental estimate and the Luscombe formula.

The aim of this study is to evaluate the efficiency of a specific organizational model for early stroke management associated with repeated public awareness campaigns on stroke warning signs. ⋯ Educational programs repeated each year are useful to the population for learning how to recognize stroke symptoms and send straight away an emergency call. Combining the emergency action with an early remote evaluation by the stroke center team and a direct admission in imaging department shortens the time-to-treatment delay. This model is reproducible in different health care systems.

Certain acute coronary syndrome electrocardiographic (ECG) patterns, which do not include ST-segment elevation, are indicative of acute coronary syndrome caused by significant arterial occlusion; these patterns are, of course, associated with significant risk to the patient and mandate a rapid response from the health care team. One such high-risk ECG pattern includes the association of the prominent T wave and J-point depression producing ST-segment depression seen in the precordial leads coupled with ST-segment elevation in lead aVr. This ECG presentation is associated with significant left anterior descending artery obstruction. We report the case of a patient with this ECG presentation who progressed over a very short time to ST-segment elevation myocardial infarction of the anterior wall.
