Use of point-of-care ultrasound in long bone fractures: a systematic review and meta-analysis.
Long bone fractures (LBFs) are among the most frequent traumatic injuries seen in emergency departments. Reduction and immobilization is the most common form of treatment for displaced fractures. Point-of-care ultrasound (PoCUS) is a promising technique for diagnosing LBFs and assessing the success of reduction attempts. This article offers a comprehensive review of the use of PoCUS for the diagnosis and reduction of LBFs. Data source MEDLINE and EMBASE databases were searched through July 19, 2015. Study selection We included prospective studies that assessed test characteristics of PoCUS in 1) the diagnosis or 2) the reduction of LBFs. The methodological quality of the included studies was evaluated using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. Data extraction Thirty studies met inclusion criteria (n=3,506; overall fracture rate 48.0%). Test characteristics of PoCUS for the diagnosis of LBFs were as follows: sensitivity 64.7%-100%, specificity 79.2%-100%, positive likelihood ratio (LR) 3.11-infinity, and negative LR zero-0.45. Sensitivity and specificity for the adequate reduction of LBFs with PoCUS were 94%-100% and 56%-100%, respectively. PoCUS diagnosis of pediatric forearm fractures in 10 studies showed a pooled sensitivity of 93.1% (95% confidence interval [CI], 87.2%-96.4%) and specificity of 92.9% (95% CI, 86.6%-96.4%), and PoCUS diagnosis of adult ankle fractures in four studies showed a pooled sensitivity of 89.5% (95% CI, 77.0%-95.6%) and specificity of 94.2% (95% CI, 86.1%-97.7%). ⋯ PoCUS demonstrates good diagnostic accuracy in all LBFs studied, especially in pooled results of diagnosis of pediatric forearm and adult ankle fractures. PoCUS is an appropriate adjunct to plain radiographs for LBFs.

Review Meta Analysis
SGEM Hot Off the Press: hypertonic saline in severe traumatic brain injury: a systematic review and meta-analysis of randomized controlled trials.
As part of the Canadian Journal of Emergency Medicine's (CJEM) developing social media strategy, 1 we are collaborating with the Skeptics' Guide to Emergency Medicine (SGEM) to summarize and critically appraise the current emergency medicine (EM) literature using evidence-based medicine principles. In the "Hot Off the Press" series, we select original research manuscripts published in CJEM to be featured on the SGEM website/podcast and discussed by the study authors and the online EM community. ⋯ Through this series, we hope to enhance the value, accessibility, and application of important, clinically relevant EM research. In this, the second SGEM HOP hosted collaboratively with CJEM, we discuss a systematic review evaluating the use of hypertonic saline in the treatment of severe traumatic brain injury. 2.

Review Meta Analysis
Hypertonic saline in severe traumatic brain injury: a systematic review and meta-analysis of randomized controlled trials.
Hypertonic saline solutions are increasingly used to treat increased intracranial pressure following severe traumatic brain injury. However, whether hypertonic saline provides superior management of intracranial pressure and improves outcome is unclear. We thus conducted a systematic review to evaluate the effect of hypertonic saline in patients with severe traumatic brain injury. ⋯ We observed no mortality benefit or effect on the control of intracranial pressure with the use of hypertonic saline when compared to other solutions. Based on the current level of evidence pertaining to mortality or control of intracranial pressure, hypertonic saline could thus not be recommended as a first-line agent for managing patients with severe traumatic brain injury.

The role of adjunctive antibiotics in the treatment of skin and soft tissue abscesses: a systematic review and meta-analysis.
To perform a review and meta-analysis on the effect of antibiotics on treatment of skin and soft tissue abscesses (SSTAs) after incision and drainage. ⋯ Despite limitations in pooling available data, there is no clear evidence to support antibiotic use in treating uncomplicated SSTAs.
