Annals of Emergency Medicine collaborated with an educational Web site, Academic Life in Emergency Medicine (ALiEM) to host a public discussion featuring the 2014 Annals article on the outpatient management of patients with a spontaneous pneumothorax by using pigtail catheters. The objective was to curate a 14-day (November 10 to 23, 2014) worldwide academic dialogue among clinicians about the article. Four online facilitators hosted the multimodal discussion on the ALiEM Web site, Twitter, and Google Hangout. ⋯ Blog comments, tweets, and video expert commentary involving the featured article are summarized and reported. The dialogue resulted in 1,023 page views from 347 cities in 49 countries on the ALiEM Web site, 279,027 Twitter impressions, and 88 views of the video interview with experts. This Global Emergency Medicine Journal Club created a virtual community of practice from around the world and identified common themes around the management of spontaneous pneumothorax, which included substantial practice variation in regard to inpatient versus outpatient management, location of chest tube, the use of aspiration, and chest radiography after placement.

Publication bias compromises the validity of systematic reviews. This problem can be addressed in part through searching clinical trials registries to identify unpublished studies. This study aims to determine how often systematic reviews published in emergency medicine journals include clinical trials registry searches. ⋯ Systematic reviews published in emergency medicine journals do not routinely include searches of clinical trials registries. By helping authors identify unpublished trial data, the addition of registry searches may improve the validity of systematic reviews.

Review Meta Analysis
A Systematic Review and Meta-analysis of D-dimer as a Rule-out Test for Suspected Acute Aortic Dissection.
The aim of this systematic review and meta-analysis is to determine the diagnostic accuracy of D-dimer as a rule-out test for acute aortic dissection. Previous meta-analyses have had methodological problems with conflicting conclusions, and new diagnostic accuracy studies have been published since. ⋯ This meta-analysis suggests that a negative D-dimer result may be useful to help rule out acute aortic dissection in low-risk patients.

Multicenter Study
Complications Associated With Nitrate Use in Patients Presenting With Acute Pulmonary Edema and Concomitant Moderate or Severe Aortic Stenosis.
We evaluate the incidence of complications associated with the use of nitrates in patients presenting with acute pulmonary edema and concomitant moderate or severe aortic stenosis compared with patients without aortic stenosis. Nitrates are contraindicated in severe aortic stenosis because of the theoretical yet unproven risk of precipitating profound hypotension. ⋯ In this retrospective study, neither moderate nor severe aortic stenosis was associated with a greater risk of clinically relevant hypotension requiring intervention when nitroglycerin was used for acute pulmonary edema. Future studies should investigate safety and efficacy of nitroglycerin for patients with aortic stenosis because this study was limited by a small sample size and design limitations. Cautious use of nitroglycerin in patients with moderate or severe aortic stenosis and presenting with acute pulmonary edema may be a safer strategy than traditionally thought.
