The Cost Does Not Outweigh the Benefit: Pathologic Evaluation of Wrist Ganglion Cysts Should Not Be Routine.

Background: As health care costs in the United States continue to rise, there is increasing attention on cost-saving measures. One area of investigation is the utility of pathologic examination of specimens from routine procedures with a suspected benign pathology. We assessed the utility and cost of routine pathologic analysis for wrist ganglion cyst excision.

Early Clinical Outcomes of a Novel Antibiotic-Coated, Non-Crosslinked Porcine Acellular Dermal Graft after Complex Abdominal Wall Reconstruction.

Background: Non-crosslinked porcine acellular dermal grafts (NCPADG) are currently the mainstay biomaterial for abdominal wall reconstruction (AWR) in complex hernia patients. We report early clinical outcomes using a novel rifampin/minocycline-coated NCPADG for AWR.

Study Design: A multi-institutional retrospective review was performed of patients who underwent ventral hernia repair using XenMatrix AB Surgical Graft (CR Bard, Inc [Davol]).

Outcomes after anterior cervical discectomy and fusion in professional athletes.

Background: Significant controversy exists regarding when an athlete may return to contact sports after anterior cervical discectomy and fusion (ACDF). Return-to-play (RTP) recommendations are complicated due to a mix of medical factors, social pressures, and limited outcome data.

Objective: The aim of this study was to characterize our diagnostic and surgical criteria, intervention, postoperative imaging results, and rehabilitation and report RTP decisions and outcomes for professional athletes with cervical spine injuries.

Postconcussion syndrome: a review of pathophysiology and potential nonpharmacological approaches to treatment.

The incidence of all-cause concussions in the United States is estimated to range from 1.6 to 3.8 million annually, with the reported number of sport- or recreation-related concussions increasing dramatically, especially in youth sports.

Gratings for tunable lasers: using multidielectric coatings to improve their efficiency.

The first results of a theoretical and experimental study are presented showing that a significant enhancement of the efficiency of gratings used as wavelength selectors for cw tunable lasers may be achieved with adequate dielectric coatings. It is found that, in some cases, the energy absorbed by the grating surface can be reduced by a factor >2. The output power of a cw Rh640 dye laser was practically multiplied by the same factor.
