Abstract:

The seal of the implanted round window membrane to resist Streptococcus pyogenes invasion from the middle ear was investigated in 12 cats. Results showed that the implanted round window membrane is able to form a barrier for S pyogenes starting 1 week postimplantation. Under normal conditions S pyogenes did not pass through the round window membrane, nor through the gap that existed between the membrane and the prosthesis. Mechanical disruption of the round window seal, however, and severe inflammatory response to S pyogenes caused the infection to extend into the inner ear.

Abstract:

Driveline infection has been a persistent problem with mechanical cardiac assist devices. The reported incidence of infection has been low in patients who receive a Jarvik 2000 continuous-flow left ventricular assist device when a skull-pedestal driveline exit site is used. We evaluated whether this is also true when a subcostal driveline exit site is used. We reviewed baseline demographic variables, postimplantation vital signs, laboratory values, and culture results in patients who underwent Jarvik 2000 implantation at our center from April 2000 through October 2009, including follow-up thro

Abstract:

Left ventricular assist devices improve survival prospects in patients with end-stage heart failure; however, infection complicates up to 59% of implantation cases. How many of these infections are caused by multidrug-resistant organisms is unknown.

We retrospectively evaluated the incidence of multidrug-resistant organisms and the independent risk factors associated with them in 57 patients who had permanent left ventricular assist dev

Objective: The purpose of the present investigation was to analyze the effets of zidovudine on the postimplantation embryo and fetus.Methods: Pregnant Sprague-Dawley rats were given various doses (10 mg/kg, 30 mg/kg, 150 mg/kg) of zidovudine or saline by an endotracheal tube during the period of embryogenesis (days 6–8, 9–11, 6–11 postconception). The animals were sacrificed on days 18–19 of pregnancy, and their fetuses were removed by hysterotomy. Autopsies under low (15×) and high (40×) power light microscopy were performed on all fetuses.Results: There was no statistically significant diffe

Abstract:

✓ In the past, pain control for chronic pain syndromes using narcotic infusion has been carried out primarily via the intrathecal (subarachnoid) route. This report presents one of the first large series of terminally ill cancer patients with intractable pain treated with continuous epidural morphine infusions by means of implanted pumps and epidural spinal catheters. The purpose of the study was to demonstrate that the epidural route is effective with minimal complications, and that screening with temporary epidural catheter infusions results in a high rate of subsequent pain relief.

Abstract:

Abstract Background Periprosthetic joint infection (PJI) is a devastating complication of joint replacement surgery. Most observational studies of PJI are retrospective or single-center, and reported management approaches and outcomes vary widely. We hypothesized that there would be substantial heterogeneity in PJI management and that most PJIs would present as late acute infections occurring as a consequence of bloodstream infections. Methods The Prosthetic joint Infection in Australia and New Zealand, Observational (PIANO) study is a prospective study at 27 hospitals. From July 2014 through

Grossly, there was no distortion with preserved leaflets and lack of calcification. Good biocompatibility, nonreactivity, and low antigenicity, combined with neointimal and endothelial layer generation within the conduit might explain the low infection rates and minimal thrombogenicity.

Abstract:

Summary: Postimplantation syndrome (PIS) following endovascular aortic aneurysm repair (EVAR) is a poorly understood phenomenon occurring in the early post-operative course. The underlying aetiology, risk factors, clinical sequalae, and treatment options, are largely unknown. The lack of any standardised diagnostic criteria limits current research in this field. The MEDLINE database was interrogated using a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) search strategy. Five search terms were used; “postimplantation syndrome” AND “aneurysm”, AND “infection”, AND “c

Direct skeletal fixation (DSF) involves attaching the intramedullary portion of a prosthesis directly to the skeletal residuum, providing an alternative for amputees unable to mobilise with socket-based prostheses. This study investigates the effects of DSF on physical and mental health at 6- and 8-year follow-up for military bilateral transfemoral amputees in the UK. Eight male bilateral transfemoral military amputees who underwent implantation with the Osseointegration Group of Australia–Osseointegration Prosthetic Limb prosthesis consented to participate in the study.

This study is initiated with the aim of regulating the release of silver (Ag) as an antibacterial agent from the micro‐arc oxidation (MAO) coating. Herein, an external 5 wt% Tin(II) chloride (SnCl2) containing biodegradable polycaprolactone (PCL) layer is formed on the 0.8 wt% Ag‐incorporated MAO coating by the dip coating method. 5 wt% SnCl2 addition into PCL provides a steady release of Ag into concentrated simulated body fluid (1.5X SBF) from the underlying MAO coating at 37 °C. When the Ag release rate is taken into consideration, it is quantified as 0.0089 and 0.0586 ppm day−1 for PCL‐cov

Abstract:

Partial cystectomy procedures for urinary bladder–related dysfunction involve long recovery periods, during which urodynamic studies (UDS) intermittently assess lower urinary tract function. However, UDS are not patient-friendly, they exhibit user-to-user variability, and they amount to snapshots in time, limiting the ability to collect continuous, longitudinal data. These procedures also pose the risk of catheter-associated urinary tract infections, which can progress to ascending pyelonephritis due to prolonged lower tract manipulation in high-risk patients.
