The article deals with the preparation, properties and the usage of polymer barrier films. The problem of exfoliation and dispersion of the filler in the polymer matrix and mechanical properties of barrier films is discussed. This problem is connected with the use of nanofiller either in the polymer matrix or on the surface of prepared films. Together the evaluating comparison of used nanofille...

Background Polypropylene material is widely used in gynecological surgery. There are few reports regarding its carcinogenic potential. There is lack of evidence supporting tumor formation directly attributed to the use of polypropylene material. Case This patient is a 49-year-old woman with a history of stress urinary incontinence which required a MiniArc® Sling who presented with a hard, ten...

Objective: To evaluate surgical handling, prolapse correction and complication rate of polypropylene mesh. Methods: A retrospective review of patients who had pelvic floor repair using polypropylene mesh(PPM) and intra-vaginal sling(IVS), between January 2003 and July 2005. All patients were followed-up for a period of 6weeks to 12months.The effectiveness and complications following PPM inserti...

Background: The tension-free hernioplasty as introduced by Lichtenstein has gained increasing acceptance during the last decade. This study compared two methods of mesh fixation. Material and Methods: Fifty-four patients undergoing sixty repairs were randomized into two groups. In control group polypropylene mesh was secured with 2/0 polypropylene sutures and skin closed with 2/0 polyamide blac...

Intentional degradation by pro-oxidant agents, many of which are metal-based, can result in uncertainty as to the time of biodegradation. Polyacetal (POM) is a thermoplastic polymer commercially classified as an engineering polymer and contains carbon, hydrogen and oxygen. The depolymerization of POM during processing can enhance thermal decomposition. The aim of this study was to investigate t...
