Better Understanding the Orthopaedic Burden of Neurosurgical Intervention for Drug-Resistant Epilepsy in Pediatric Patients.

Background Hemispherectomies, hemispherotomies and lobectomies of the brain are neurosurgical techniques used to treat drug-resistant epilepsy (DRE). While effective for seizure control, these neurosurgical interventions can produce significant functional deficits including hemiparesis and iatrogenic cerebral palsy. In this study, we aim to evaluate the resulting MSK pathology following surgery for DRE so that we may establish the incidence of new MSK pathology, identify risk factors for developing MSK pathology, and guide orthopaedic follow-up care.

The Utility of Routine Radiographic Monitoring in Pediatric Osteoarticular Infections.

Background: Pediatric musculoskeletal (MSK) infections broadly include isolated osteomyelitis (OM), septic arthritis (SA), and combined infections (OM+SA). These diagnoses are often monitored with serum inflammatory markers and serial radiographs to monitor treatment response and development of negative sequelae, despite limited data supporting these practices. The purpose of this study is to evaluate the utility of obtaining serial radiographic follow-up for pediatric osteoarticular infections.

Academic Influence and Its Relationship to Industry Payments in Orthopaedic Surgery.

Background: The Hirsch index (h-index) quantifies research publication productivity for an individual, and has widely been considered a valuable measure of academic influence. In 2010, the Physician Payments Sunshine Act (PPSA) was introduced as a way to increase transparency regarding U.S.

Comparison of Synovial Fluid Cytokine Levels between Traumatic Knee Injury and End-Stage Osteoarthritis.

Degenerative osteoarthritis (OA) has been associated with elevated synovial fluid cytokines. It is unclear whether traumatic knee injuries are a trigger to the chemical process that leads to OA. The purpose of this study was to compare the synovial fluid cytokine levels between knees undergoing arthroscopy due to a documented inciting injury and knees undergoing primary arthroplasty due to end-stage OA without a previous inciting injury.

α-Defensin Accuracy to Diagnose Periprosthetic Joint Infection-Best Available Test?

Background: The purpose of this study was to test the accuracy of a single synovial fluid biomarker, α-defensin, in diagnosing periprosthetic joint infection in revision total hip and revision total knee arthroplasty.

Methods: A total of 102 patients comprising 116 revision total hip arthroplasty and revision total knee arthroplasty procedures performed between May 2013 and March 2014 were prospectively evaluated. Cases were categorized as infected or notinfected using Musculoskeletal Infection Society criteria.

The α1 adrenoceptor antagonist prazosin enhances sleep continuity in fear-conditioned Wistar-Kyoto rats.

Fragmentation of rapid eye movement sleep (REMS) is well described in individuals with posttraumatic stress disorder (PTSD) and likely has significant functional consequences. Fear-conditioned rodents may offer an attractive model of the changes in sleep that characterize PTSD. Following fear conditioning (FC), Wistar-Kyoto (WKY) rats, a strain known to be particularly stress-sensitive, have increased REMS fragmentation that can be quantified as a shift in the distribution of REMS episodes towards the more frequent occurrence of sequential REMS (inter-REMS episode interval≤3 min) vs.

Urological complications following use of recombinant human bone morphogenetic protein-2 in anterior lumbar interbody fusion: presented at the 2012 Joint Spine Section Meeting: clinical article.

Object: The goal of this study was to compare the urological complications in patients after anterior lumbar interbody fusion (ALIF) with and without the use of recombinant human bone morphogenetic protein-2 (rhBMP-2).

Methods: The authors retrospectively reviewed the medical records of all patients who underwent ALIF with and without rhBMP-2 between January 2002 and August 2010. Patient demographic, operative, and complication information was analyzed.
