Tissue adhesives for traumatic lacerations: a systematic review of randomized controlled trials.
To summarize the best available evidence for the effect of tissue adhesives (TAs) in managing traumatic lacerations in children and adults. ⋯ TAs are an acceptable alternative to SWC for simple traumatic lacerations. No difference in cosmesis was found between TAs and SWC, or between different TAs. Tissue adhesives offer the benefits of decreased procedure time and less pain, compared with SWC. A small increased rate of dehiscence with TAs must be considered when choosing the closure method (NNH = 25).

The last decade has witnessed a growing awareness of medical error and the inadequacies of our health care delivery systems. The Harvard Practice Study and subsequent Institute of Medicine Reports brought national attention to long-overlooked problems with health care quality and patient safety. ⋯ The Patient Safety Task Force of the Society for Academic Emergency Medicine (SAEM) was charged with that mission. The curriculum presented here offers an approach to teaching patient safety in emergency medicine.

A relatively new application of emergency ultrasound is its use in the diagnosis of pneumothorax. In patients with major trauma, early detection and treatment of pneumothorax are vital. Chest radiography in these patients is limited to anteroposterior (AP) supine films, in which radiographic features of pneumothorax may be quite subtle. ⋯ Sonographic features of pneumothorax have been identified in a number of studies. The technique involves identification of the pleural line and observation for features such as "lung sliding" and comet-tail artifacts, which are absent in pneumothorax. Based on a review of the literature, the author describes these features and discusses the utility of emergency ultrasound in detecting pneumothorax.

Sudden cardiac arrest (CA) claims approximately 1,200 lives daily in the United States. Cardiopulmonary resuscitation attempts have so far achieved suboptimal results, and even when restoration of spontaneous circulation (ROSC) is achieved, about 30% of survivors suffer permanent brain damage. This illustrates the need for an improved basic scientific understanding of the pathophysiology of global cerebral injury caused by whole-body ischemia/reperfusion (I/R) injury following CA. ⋯ The mechanisms underlying brain edema formation elicited by CA are unclear. New scientific findings of the roles of blood-brain barrier (BBB) permeability, matrix metalloproteinases (MMPs) of a family of proteases, aquaporin 4 (AQP4) of a family of membrane water-channel proteins, and the N-methyl-D-aspartate (NMDA) receptors in the mechanisms underlying CA-elicited brain edema were reviewed. By defining the roles of BBB permeability, MMPs, AQP4, and NMDA receptors in CA-induced brain edema formation, effective new therapeutic strategies to extend cellular and tissue survival, and preserve neurologic function following CA may be feasible.

Smoking remains the leading preventable cause of morbidity and mortality in the United States. The efficacy of emergency department (ED)-based patient screening and counseling for smoking cessation is not currently known. ⋯ Strong evidence exists, in the primary care setting, that smoking cessation screening and counseling are effective. Limited data exist for ED-based practice, but, based on the burden of disease, relative ease of intervention, and likely efficacy, routine screening of all patients for tobacco use and referral of smokers to primary care and cessation programs are recommended.
