Intraoperative Electromyogram Analysis of Postural Musculature With Three-dimensional Screen Display Versus Operating Microscope in Ophthalmic Surgery: A Clinical Methods Study.

Background And Objective: To objectively analyze the effect of three-dimensional screen-based surgery (3D SBS) versus traditional operating microscope (TOM) on operating surgeon posterior chain postural musculature during ophthalmic surgery. We hypothesized an increase in median amplitude of electromyography (EMG) signals when using a TOM compared to 3D SBS. The goal was to assess surgical ergonomics that may contribute to cervical and lumbar spine pathology.

Preoperative opioid usage predicts markedly inferior outcomes 2 years after reverse total shoulder arthroplasty.

Background: Reverse total shoulder arthroplasty (RTSA) has proved to be a highly effective treatment for rotator cuff-deficient conditions and other end-stage shoulder pathologies. With value-based care emerging, identifying predictive factors of outcomes is of great interest. Although preoperative opioid use has been shown to predict inferior outcomes after anatomic total shoulder arthroplasty and rotator cuff repair, there is a paucity of data regarding its effect on outcomes after RTSA.

Percutaneous endoscopic gastrostomy tube placement in amyotrophic lateral sclerosis: a case series with a multidisciplinary, team-based approach.

Background: Amyotrophic lateral sclerosis is a progressive neurodegenerative disease that affects motor neurons. When bulbar symptoms impair oral nutritional uptake, guidelines recommend percutaneous endoscopic gastrostomy tube placement. Studies evaluating the appropriate timing and procedural method of placement of gastrostomy tubes have been published; however, no study has been published that evaluated outcomes from a team-based approach to percutaneous endoscopic gastrostomy placement.

Initial Evaluation by a Non-Surgeon Provider Does Not Delay the Surgical Care of Pediatric Forearm and Elbow Trauma in a Walk-In Orthopaedic Clinic.

Introduction Walk-in and after-hours clinics are being increasingly utilized in orthopedics and are especially beneficial for patients with simple sprains, fractures, or overuse injuries that might otherwise require an emergency room visit. To meet the increased patient load, additional staffing often is required, which might include a family medicine physician, nurse practitioner, or physician assistant. Few studies have evaluated the performance of these non-surgeon providers in an orthopedic clinical setting.

Somatic mosaicism for Duchenne dystrophy: evidence for genetic normalization mitigating muscle symptoms.

We describe a young adult male presenting with cardiac failure necessitating cardiac transplantation 7 months after presentation. Skeletal muscle biopsy showed mosaic immunostaining for dystrophin. DNA studies showed somatic mosaicism for a nonsense mutation in the dystrophin gene (Arg2905X).
