Observational Study
Effectiveness and Validity of Sonographic Upper Airway Evaluation to Predict Difficult Laryngoscopy.
Our objective was to evaluate the effectiveness of 9 airway sonographic parameters imaged from the submandibular view as predictors of difficult laryngoscopy. Additionally, we aimed to evaluate the validity of the models of combined sonographic and clinical tests in predicting difficult laryngoscopy. ⋯ Sonographic predictors may help identify patients with difficult laryngoscopy. Individual measures have unsatisfactory diagnostic profiles. The models based on combined tests have improved diagnostic value.

Comparative Study
Comparison of Ultrasound-Guided to Fluoroscopy-Guided Biceps Tendon Sheath Therapeutic Injection.
Biceps tendinitis is a source of anterior shoulder pain and is amenable to therapeutic injection. Studies have shown greater accuracy with image-guided compared to unguided injection of the biceps tendon sheath. There is no literature comparing ultrasound-guided to fluoroscopy-guided biceps tendon sheath injection. The purpose of this study was to compare clinical outcomes, complication rates, procedure success rates, and financial costs of the two imaging-guided methods. ⋯ Compared to fluoroscopy-guided biceps tendon sheath injection, ultrasound had higher initial- and final-pass success rates, visualized abnormalities before injection, and had similar pain relief and complication rates. Ultrasound is more accurate and has greater diagnostic benefits than unguided or fluoroscopy-guided biceps tendon sheath injection.

Case Reports
Epipericardial Fat Necrosis: Sonographic Findings and Their Correlation With Computed Tomography.
Epipericardial fat necrosis is a rare cause of chest pain. It presents as pleuritic pain in an otherwise healthy patient. ⋯ We report 4 cases admitted to our institutional emergency department with chest pain. Among other tests, chest wall sonography was requested in these patients and showed special findings that should be evaluated with chest computed tomography.
