Comparative Study
Comparison of sonographically guided intra-articular injections at 3 different sites of the knee.
Sonographically guided injections show more accuracy than blind injections, but there are no reports comparing sonographically guided intra-articular injection approaches. This study examined the accuracy of sonographically guided intra-articular injections at 3 different sites of the knee using medial, midlateral, and superolateral portals. ⋯ Sonographically guided intra-articular injections in the midlateral or superolateral portal may increase the accuracy of knee joint injections.

The purpose of this study was to investigate the sensitivity and diagnostic value of convex probe endobronchial sonographically guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of granulomatous mediastinal lymphadenitis. ⋯ In the diagnosis of granulomatous lymphadenitis, EBUS-TBNA, with high sensitivity and a minimum complication rate, is an alternative to mediastinoscopy.
