Randomized Controlled Trial Comparative Study
Emergence agitation in children after propofol versus halothane anesthesia.
The administration of anesthetic agents is associated with a high incidence of emergence agitation in children. Halothane and propofol appear to cause much less emergence agitation. The aim of this study was to compare the incidence of emergence agitation in children receiving either propofol or halothane anesthesia for a variety of surgical treatments using the Pediatric Anesthesia Emergence Delirium (PAED) scale. ⋯ In children, the administration of propofol maintenance anesthesia is associated with a significantly higher incidence of emergence agitation than halothane maintenance anesthesia.

Progress in the management of myocardial infarction has contributed to the increased population of patients with asymptomatic left ventricular dysfunction or congestive heart failure. These patients are at high risk of sudden cardiac death. Factors that worsen this prognosis include exacerbation of coronary artery disease and acute coronary syndrome. We aimed to define and compare risk factors of acute coronary syndrome and sudden cardiac death as well as the cumulative incidence of both in patients after myocardial infarction with asymptomatic left ventricular dysfunction or congestive heart failure during a 2-year follow-up period. ⋯ Predictors of acute coronary syndrome and sudden cardiac death differ in patients after myocardial infarction with asymptomatic left ventricular dysfunction or chronic heart failure and are inconsistent at different stages of development of chronic heart failure.

Case Reports
Early prediction of ventricular recovery in Takotsubo syndrome using stress and contrast echocardiography.
Takotsubo syndrome is a primary, stress-provoked acquired cardiomyopathy mimicking acute myocardial infarction. Because of the less severe prognosis of takotsubo patients, a reliable method of predicting complete functional recovery has great practical value. ⋯ Microcirculation assessment using myocardial contrast echocardiography as well as early contractile reserve in a low-dose dobutamine echocardiographic test might be useful in the prediction of functional recovery in suspected takotsubo syndrome.

Ageing reduces the resting blood flow to the skin as well as the blood flow response to thermal stimuli. However, the interrelationships between skin thickness, subcutaneous fat, and skin blood flow in determining the heat dissipation characteristics of the skin have not been investigated. ⋯ The results support a reduction in both the resting and post local heat skin blood flows associated with ageing. Some of this may be due to a reduction in dermal layer thickness due to ageing.
