Multicenter Study Comparative Study
High discordance of chest x-ray and computed tomography for detection of pulmonary opacities in ED patients: implications for diagnosing pneumonia.
To evaluate the diagnostic performance of chest x-ray (CXR) compared to computed tomography (CT) for detection of pulmonary opacities in adult emergency department (ED) patients. ⋯ In this multicenter cohort of adult ED patients with acute cardiopulmonary symptoms, CXR demonstrated poor sensitivity and positive predictive value for detecting pulmonary opacities. Reliance on CXR to identify pneumonia may lead to significant rates of misdiagnosis.

Randomized Controlled Trial Comparative Study
Comparison of 2 cuff inflation methods before insertion of laryngeal mask airway for safe use without cuff manometer in children.
This prospective, randomized trial was conducted to establish whether the pediatric laryngeal mask airway (LMA) could be used without any concerns for abnormally high intra-cuff pressure when a cuff of the LMA was inflated with half the maximum recommended inflation volume or the resting volume before insertion. ⋯ Both methods of the LMA cuff inflation before insertion provided an acceptable range of intra-cuff pressure with adequate pharyngeal sealing without any intervention after insertion.
