Review Meta Analysis
Dietary sugars versus glucose tablets for first-aid treatment of symptomatic hypoglycaemia in awake patients with diabetes: a systematic review and meta-analysis.
While glucose tablets have been advocated for treating symptomatic hypoglycaemia in awake patients, dietary sugars may be more convenient. We performed a systematic review to compare the impact of these treatment options on the relief of symptomatic hypoglycaemia, time to resolution of symptoms, blood glucose levels, complications and hospital length of stay. ⋯ When compared with dietary sugars, glucose tablets result in a higher rate of relief of symptomatic hypoglycaemia 15 min after ingestion and should be considered first, if available, when treating symptomatic hypoglycaemia in awake patients.

Observational Study
Posterior reperfusion T-waves: Wellens' syndrome of the posterior wall.
Reperfusion after coronary occlusion (myocardial infarction, MI), as in Wellens' syndrome, is often represented on ECG as T-wave inversion in the leads overlying the affected myocardial wall(s). As an extension of this logic, reperfusion of the posterior wall should manifest on right precordial leads (which are opposite the posterior wall) as enlarged T-waves. ⋯ Reperfusion of the posterior wall results in higher right precordial TWa, and an even greater increase in TWa, as measured in leads V2 and V3. This observation has important implications for emergency physicians to accurately identify recent posterior infarction in patients who may be symptom free on presentation but at risk of reocclusion.

Injuries to the foot are a common cause for presentation to the ED, and imaging is often used to aid in the diagnosis. The foot can be divided into three distinct anatomical regions: the forefoot, midfoot and hindfoot. ⋯ We provide pearls to radiographic interpretation and discuss prognostic implications and classification systems. Part 1 addresses forefoot injuries, part 2 reviews midfoot injuries and part 3 covers the hindfoot.

Rates of unplanned paediatric admissions are persistently high. Many admissions are short-stay events, lasting less than 48 hours. ⋯ The emergence of intuition entwined with approaches to risk management and the role of these skills in clinical decision making, carry implications for the development of training programmes for clinicians working in PEM. Enhanced training for such groups to permit development of the supplementary skills described in this study could have the ability to improve care delivery and even reduce paediatric admissions.

Observational Study
Clinical outcomes after rescue extracorporeal cardiopulmonary resuscitation for out-of-hospital cardiac arrest.
Extracorporeal cardiopulmonary resuscitation (ECPR) has been shown to have survival benefit in patients who had in-hospital cardiac arrest (IHCA). However, limited data are available on the role of extracorporeal membrane oxygenation (ECMO) for out-of-hospital cardiac arrest (OHCA). Therefore, we aimed to investigate clinical outcomes and predictors of in-hospital mortality in patients who had OHCA and who underwent ECPR. ⋯ Survival rate for ECPR in the setting of OHCA remains poor. Our findings suggest that ECMO implantation should be very carefully considered in highly selected patients who had OHCA with little no-flow time and a reversible cause.
