Outcomes of an aseptic technique for Kirschner wire percutaneous pinning in the hand and wrist.

Introduction: Kirschner wires (K-wires) have been shown to effectively stabilize fractures of the hand and wrist, but are associated with high infection rates, which may limit its use. Previous literature has attributed the risk of infection to many different aspects of a fixation technique. However, we introduce an approach to percutaneous K-wire pinning to mitigate the risk of infection.

Epidemiology and trends of adult ice hockey injuries presenting to United States emergency departments: A ten-year analysis from 2007-2016.

Purpose: The adult population is under-represented in existing ice hockey injury studies, despite the number of United States (US) adult ice hockey players increasing from 103,533 in 2007 to 180,400 in 2016 (74%). This study establishes trends in demographics, injury location, and injury type for adult ice hockey players (≥19 years old) in the United States.

Methods: The National Electronic Injury Surveillance System (NEISS) was queried for all ice hockey injuries from January 1, 2007 to December 31, 2016.

Is pelvic lymph node dissection necessary in patients with biopsy proven Gleason 6 prostate cancer? - analysis of the SEER database.

Introduction: Since the advent of prostate-specific antigen (PSA) screening there has been a decreased incidence of lymph node positive disease (LND). Nevertheless, because of possible upgrading, LND is frequently performed with preoperative Gleason 6 prostate cancer. We utilized the Surveillance Epidemiology and End Results (SEER) database to evaluate the frequency of LND and preoperative variables for node positivity in contemporary patients with preoperative Gleason 6 disease.

The Role of Varicocele in Male Factor Subfertility.

Purpose Of Review: Varicocele may play a significant role in a subset of patients presenting with male factor infertility. Despite its relatively high prevalence amongst subfertile men, there has been controversy over the effectiveness of surgical treatments, patient selection, and when to administer treatment, particularly in the era of assisted reproductive technology.

Recent Findings: In line with earlier finding, recent evidence strongly suggests that varicocelectomy improves pregnancy rates and semen parameters.

The metastatic potential of renal tumors: Influence of histologic subtypes on definition of small renal masses, risk stratification, and future active surveillance protocols.

Objective: The influence of histology in metastatic potential is often overlooked when discussing the management options of small renal masses (SRM), with size or growth rate often serving as the triggers for the intervention. We aim to re-examine the definition of a SRM by evaluating the metastatic potential of renal masses incorporating tumor size and histology to create metastatic risk tables.

Materials And Methods: Surveillance Epidemiology and End Results (SEER)-18 registries database was queried for all cases of clear cell, papillary, and chromophobe renal cell carcinoma (RCC) diagnosed between 2004 and 2012.

Development of a bovine decellularized extracellular matrix-biomaterial for nucleus pulposus regeneration.

Painful intervertebral disc (IVD) degeneration is a common cause for spinal surgery. There is a clinical need to develop injectable biomaterials capable of promoting IVD regeneration, yet many available biomaterials do not mimic the native extracellular matrix (ECM) or promote matrix production. This study aimed to develop a decellularized injectable bovine ECM material that maintains structural and compositional features of native tissue and promotes nucleus pulposus (NP) cell (NPC) and mesenchymal stem cell (MSC) adaption.
