Acute Respiratory Failure With a Rare, Rapidly Progressing Pediatric Desmoid Tumor Anterior Mediastinal Mass.

We present an unusual case of a 6-year-old boy who presented with the sudden presence of left neck mass and acute hypoxemic respiratory failure, whose subsequent imaging demonstrated a previously undiagnosed anterior mediastinal mass (AMM) extending into the left neck. Biopsy of the mass was consistent with a desmoid tumor, which is a rare cause of AMM in children. Desmoid tumors are locally aggressive, often invading and enveloping surrounding tissues, but overall slow growing.

Barbed versus standard sutures for closure in total knee arthroplasty: a multicenter prospective randomized trial.

Barbed suture has been associated with improved closure efficiency and safety in TKA in prior studies. We performed a multicenter randomized controlled trial to determine the efficiency and safety of this technology in TKA. We prospectively randomized 411 patients undergoing primary TKA to either barbed running (n=191) or knotted interrupted suture closure (n=203).

Functional Outcomes After Arthroscopic Scapulothoracic Bursectomy and Partial Superomedial Angle Scapulectomy.

Background: Arthroscopic scapulothoracic bursectomy with partial superomedial angle scapulectomy has been described as a treatment for persistent scapulothoracic bursitis with varying results.

Purpose: To evaluate patients after arthroscopic scapulothoracic bursectomy utilizing validated functional outcome instruments.

Study Design: Case series.
