OBJECTIVE: Hemivertebrae (HV) located at the lower lumbar or lumbosacral region often produce early trunk imbalance and long compensatory curves. Because of the biomechanical characteristics of the lumbosacral junction, the rate of instrumentation failures at the region has always been high. Our study aimed to evaluate the results of posterior HV resection with lumbosacral fixation and fusion in the treatment of congenital scoliosis and to make a preliminary analysis of the possible risk factors for instrument failures...

BACKGROUND: Use of organophosphate flame retardants (PFRs) has increased over the past decade following the phase out of some brominated flame retardants, leading to increased human exposure. We recently reported that increasing maternal PFR exposure is associated with poorer pregnancy outcomes among women from a fertility clinic. Because a small epidemiologic study previously reported an inverse association between male PFR exposures and sperm motility, we sought to examine associations of paternal urinary concentrations of PFR metabolites and their partner's pregnancy outcomes...

INTRODUCTION: It has been suggested that sudden cardiac death (SCD) contributes around 50% of cardiovascular and 27% of all-cause mortality in hemodialysis patients. The true burden of arrhythmias and arrhythmic deaths in this population, however, remains poorly characterised. Cardio Renal Arrhythmia Study in Hemodialysis (CRASH-ILR) is a prospective, implantable loop recorder single centre study of 30 established hemodialysis patients and one of the first to provide long-term ambulatory ECG monitoring...

BACKGROUND: Breast reconstruction with tissue expander is the most common mode of reconstruction following mastectomy. Infection necessitating tissue expander removal is a significant complication leading to patient distress as well as increased health care costs. METHODS: Over 3 years, 127 breast reconstructions with tissue expanders were performed by a single surgeon. Fifty-nine of these reconstructions were performed using a standardized protocol in which patients washed with chlorhexidine several days prior to surgery and received intravenous antibiotics preoperatively...

PURPOSE: Numerous techniques are used to prevent infection after immediate implant-based breast reconstruction. Postoperative antibiotic prophylaxis (PAP) is commonly prescribed to decrease the risk of reconstructive failure, despite conflicting evidence regarding its effectiveness. We sought to determine whether PAP decreases the risk of infection-related explantation in the setting of immediate prosthesis-based breast reconstruction. METHODS: Using Truven MarketScan databases, we identified all patients who underwent immediate implant reconstruction between 1/2010-6/2014 with at least 6 months of follow-up...

This article reports the degradation and biological properties of as-drawn Mg-4Zn-1Sr (designated as ZSr41) and pure Mg (P-Mg) wires as bioresorbable intramedullary pins for bone repair. Specifically, their cytocompatibility with bone marrow derived mesenchymal stem cells (BMSCs) and degradation in vitro, and their biological effects on peri-implant tissues and in vivo degradation in rat tibiae were studied. The as-drawn ZSr41 pins showed a significantly faster degradation than P-Mg in vitro and in vivo. The in vivo average daily degradation rates of both ZSr41 and P-Mg intramedullary pins were significantly greater than their respective in vitro degradation rates, likely because the intramedullary site of implantation is highly vascularized for removal of degradation products...

REVIEW
Devang Sharma, Ryan P Smith
Placement of a penile prosthesis is an excellent option for well-selected patients, offering high patient satisfaction and a low rate of complications. Most urologists who perform the procedure are not high volume implanters and may have limited experience with troubleshooting intraoperative issues. In this review, the authors use current literature to provide recommendations for the management of various intraoperative issues such as difficultly with dilation, incongruent measurement, perforation, urethral injury, crossover, complications of reservoir placement, penile curvature, glans mobility, and hemostasis are all discussed...

The inflatable penile prosthesis (IPP) is the gold standard surgical treatment for medical refractory erectile dysfunction (ED). While the modern IPP has enjoyed high satisfaction rates as a product of its continued innovation, reliability, and performance, patient dissatisfaction can still occur. IPP implantation restores physiologic function with cosmetic and psychological consequences, both of which place inherent emphasis on preoperative counseling and expectation management. This review aims to highlight the complex nature of such counseling and provide practitioners with a roadmap to navigate the landscape...

Penile prosthesis implant surgery is an effective management approach for a number of urological conditions, including medication refractory erectile dysfunction (ED). Complications encountered post-operatively include infection, bleeding/hematoma, and device malfunction. Since the 1970s, modifications to these devices have reduced complication rates through improvement in antisepsis and design using antibiotic coatings, kink-resistant tubing, lock-out valves to prevent autoinflation, and modified reservoir shapes...

REVIEW
Michael Lao, R James Graydon, Jared M Bieniek
The inflatable penile prosthesis (IPP) is an effective erectile dysfunction (ED) treatment modality when oral and injectable therapies fail to achieve satisfactory results. Unfortunately, infection of the prosthetic remains a dreaded complication occurring in a small fraction of patients despite advances in device design and surgical techniques. With a prosthetic infection or erosion, classic management has included removal of all hardware with thorough irrigation of the infected spaces. To prevent corporal fibrosis and scarring that can make a subsequent implant challenging, an immediate salvage procedure with a three-piece prosthesis has been advocated when possible...

BACKGROUND: Self-expanding nitinol stents must be oversized at least by a minimal amount to ensure contact with the vessel wall and prevent migration. Once the stent is deployed it exerts a continuous force upon the vascular wall, termed chronic outward force (COF). Animal studies have found an increased neointimal hyperplasia in stents with high oversizing and thus high COF. Data about correlation between COF and neointimal hyperplasia in humans are currently lacking. The objective of the BIOFLEX-COF trial is to prospectively investigate differences in formation of intimal hyperplasia at 1 and 2 years after implantation of nitinol stents with high versus low COF in de novo femoropopliteal occlusive arterial lesions...
