Mobile health has promising potential in improving healthcare delivery by facilitating access to expert advice. Enabling experts to review images on their smartphone or tablet may save valuable time. This study aims at assessing whether images viewed by medical specialists on handheld devices such as smartphones and tablets are perceived to be of comparable quality as when viewed on a computer screen. ⋯ This study suggests that handheld devices could be a substitute for computer screens for teleconsultation by physicians working in emergency settings.

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.

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.
