Diagnostic Accuracy of Point-of-Care Lung Ultrasonography and Chest Radiography in Adults With Symptoms Suggestive of Acute Decompensated Heart Failure: A Systematic Review and Meta-analysis.

Importance: Standard tools used to diagnose pulmonary edema in acute decompensated heart failure (ADHF), including chest radiography (CXR), lack adequate sensitivity, which may delay appropriate diagnosis and treatment. Point-of-care lung ultrasonography (LUS) may be more accurate than CXR, but no meta-analysis of studies directly comparing the 2 tools was previously available.

Objective: To compare the accuracy of LUS with the accuracy of CXR in the diagnosis of cardiogenic pulmonary edema in adult patients presenting with dyspnea.

Multicenter registry of balloon catheter sinusotomy outcomes for 1,036 patients.

Objectives: This study assesses the safety and effectiveness of balloon catheters used as instruments in sinus surgery in a "real-world" multicenter registry of 1,036 patients across 27 US otolaryngology practices.

Methods: Data were collected by standardized chart review with centralized database administration for all consecutive functional endoscopic sinus surgeries that included the use of balloon catheters across the 18-month time period from December 2005 to May 2007.

Results: Balloon catheters were used in 3,276 peripheral (maxillary, frontal, and sphenoid) sinuses, for an average of 3.
