Review Meta Analysis
Systematic review and meta-analysis of routine total body CT compared with selective CT in trauma patients.
Full-body CT scanning is increasingly being used in the initial evaluation of severely injured patients. We sought to analyse the literature to determine the benefits of full-body scanning in terms of mortality and length of time spent in the emergency department (ED). ⋯ We eagerly await the results of randomised controlled trials. Firm clinical outcome data are expected to emerge in the near future, though data on cost and radiation exposure will be needed before definitive conclusions can be made.

To externally evaluate the accuracy of the new Vancouver Chest Pain Rule and to assess the diagnostic accuracy using either sensitive or highly sensitive troponin assays. ⋯ The new Vancouver Chest Pain Rule should be used for the identification of low risk patients presenting to EDs with symptoms of possible ACS, and will reduce the proportion of patients requiring lengthy assessment; however we recommend further outpatient investigation for coronary artery disease in patients identified as low risk.

Studies suggest that headache accounts for approximately 1% of pediatric emergency department (ED) visits. ED physicians must distinguish between primary headaches, such as a tension or migraine, and secondary headaches caused by systemic disease including neoplasm, infection, or intracranial hemorrhage. ⋯ Once the diagnosis of migraine has been made, the ED physician is faced with the challenge of determining appropriate abortive treatment. This review summarizes the most recent literature on pediatric migraine with an emphasis on diagnosis and abortive treatment in the ED.

Dabigatran is an oral direct thrombin inhibitor (DTI) licensed for stroke prevention in atrial fibrillation and likely to be soon approved in Europe for treatment of venous thrombosis. Predictable pharmacokinetics and a reduced risk of intracranial haemorrhage do not negate the potential risk of haemorrhage. Unlike warfarin, there is no reversal agent and measurement of the anticoagulant effect is not 'routine'. ⋯ If bleeding is life/limb threatening, consider an additional haemostatic agent. There is currently no evidence to support the choice of one haemostatic agent (FEIBA, recombinant factor VIIa, prothrombin complex concentrates) over another. Choice will depend on access to and experience with available haemostatic agent(s).

Observational Study
The Effect of Point-of-care Ultrasonography on Emergency Department Length of Stay and Computed Tomography Utilization in Children With Suspected Appendicitis.
The role of clinician-performed ultrasonography (US) for suspected appendicitis is unclear. Published data conclude that US has high specificity to rule in the diagnosis of appendicitis, with variable sensitivity to rule it out. Newer data suggest that point-of-care (POC) US may have similar test characteristics. Our objective was to evaluate the effect of POC US in children with suspected appendicitis and its effect on emergency department (ED) length of stay (LOS) and computed tomography (CT) utilization. ⋯ It may be feasible to reduce ED LOS and avoid CT scan when using POC US to evaluate children with suspected appendicitis. Test characteristics for POC US have high specificity to rule in appendicitis, similar to radiology US. Addition of POC US prior to sequential radiology imaging was safe, without missed cases of appendicitis or negative laparotomies.
