INTRODUCTION: Minimal evidence exists to guide the surgeon on the risk of complications when performing abdominal wall reconstruction (AWR) in the presence of active infection, contamination or enterocutaneous fistula. This study aims to establish the outcomes of contaminated complex AWR. METHODS: Analysis was conducted according to PRISMA guidelines. Systematic search of the MEDLINE, EMBASE and Pubmed databases was performed. Studies reporting exclusively on single-staged repair of contaminated complex AWR were included...

BACKGROUND: The rates of recurrent prolapse after perineal proctectomy vary widely in the literature, with incidences ranging between 0% and 50%. The Thiersch procedure, first described in 1891 for the treatment of rectal prolapse, involves encircling the anus with a foreign material with the goal of confining the prolapsing rectum above the anus. The Bio-Thiersch procedure uses biological mesh for anal encirclement and can be used as an adjunct to perineal proctectomy for rectal prolapse to reduce recurrence...

BACKGROUND: The use of mesh in prolapse surgery is controversial, leading to a number of enquiries into its safety and efficacy. OBJECTIVE: To compare synthetic non-absorbable mesh inlay, biological graft and mesh kit with a standard repair in terms of clinical effectiveness, adverse effects, quality of life (QoL), costs and cost-effectiveness. DESIGN: Two randomised controlled trials within a comprehensive cohort (CC) study. Allocation was by a remote web-based randomisation system in a 1 :1 : 1 ratio (Primary trial) or 1 : 1 : 2 ratio (Secondary trial), and was minimised on age, type of prolapse repair planned, need for a concomitant continence procedure, need for a concomitant upper vaginal prolapse procedure and surgeon...

BACKGROUND: miRNAs are a class of noncoding RNA molecules that modulate gene expression after transcription. It is known that miRNAs are involved in various cellular processes of both normal and diseased skin. Recently, differential expressions of miRNAs have been reported and associated with several immunologic and inflammatory disorders, which indicate a common role in fundamental biologic processes. OBJECTIVE: To collect and review data from the literature on involvement of miRNA in inflammatory skin disorders...

Solvent excluded surface (SES) is one of the most popular surface definitions in biophysics and molecular biology. In addition to its usage in biomolecular visualization, it has been widely used in implicit solvent models, in which SES is usually immersed in a Cartesian mesh. Therefore, it is important to construct SESs in the Eulerian representation for biophysical modeling and computation. This work describes a software package called Eulerian solvent excluded surface (ESES) for the generation of accurate SESs in Cartesian grids...

INTRODUCTION: One-stage implant-based breast reconstruction has been recently improved by the introduction of biological [acellular dermal matrix (ADM)] and synthetic meshes. Advantages of ADMs in implant-based breast reconstruction derive from the expansion of the space available for the direct positioning of an implant, but their use could be associated with several complications. Although the majority of complications can be easily managed, mistakes in dealing with the first clinical signs of a potential adverse event can lead to implant loss...

INTRODUCTION: Double-layer dermal grafts are used for the management of complicated abdominal wall hernias in obese, high risk patients. The method has not yet been used in case of emergency in septic/dirty environment. CASE REPORT: A 76-year old female patient (BMI 36.7kg/m(2)) was admitted with mechanical bowel obstruction and sepsis caused by a third time recurred, incarcerated and eventrated abdominal wall hernia. During the emergency surgery perforation of the terminal ileum and the ascending colon was detected, along with a feculent peritonitis and extended abdominal wall necrosis...

BACKGROUND: New biodegradable synthetic and biologic hernia implants have been promoted for rapid integration and tissue reinforcement in challenging repairs, e.g. at the hiatus or in contaminated wound fields. Interestingly, experimental data to support or falsify this assumption is scarce. METHODS: Synthetic (BioA(®)) and biologic implants (porcine and bovine collagen matrices Strattice(®) and Veritas(®)) have been tested in experimental onlay hernia repair in rats in observation periods of 30 and 60 days...

BACKGROUND: The use of transvaginal mesh and biological graft material in prolapse surgery is controversial and has led to a number of enquiries into their safety and efficacy. Existing trials of these augmentations are individually too small to be conclusive. We aimed to compare the outcomes of prolapse repair involving either synthetic mesh inlays or biological grafts against standard repair in women. METHODS: We did two pragmatic, parallel-group, multicentre, randomised controlled trials for our study (PROSPECT [PROlapse Surgery: Pragmatic Evaluation and randomised Controlled Trials]) in 35 centres (a mix of secondary and tertiary referral hospitals) in the UK...

OBJECTIVE: The aim of the study was to evaluate biosynthetic absorbable mesh in single-staged contaminated (Centers for Disease Control class II and III) ventral hernia (CVH) repair over 24 months. BACKGROUND: CVH has an increased risk of postoperative infection. CVH repair with synthetic or biologic meshes has reported chronic biomaterial infections and high hernia recurrence rates. METHODS: Patients with a contaminated or clean-contaminated operative field and a hernia defect at least 9 cm had a biosynthetic mesh (open, sublay, retrorectus, or intraperitoneal) repair with fascial closure (n = 104)...

BACKGROUND: The U.S. Centers for Disease Control requires 90 days after surgery using an implant to diagnose or show the absence of a surgical site infection (SSI). However, many databases only track outcomes up to 30 days. The cost and effort to increase follow-up to 90 days after surgery is high and the benefit is unclear. We hypothesize that the majority of SSIs after ventral hernia repair occur within 30 days of surgery. PATIENTS AND METHODS: All patients who underwent ventral hernia repair (with or without mesh) from 2010-2015 at a single institution were evaluated for evidence of SSI...

We developed a porous poly-L-lactic acid (PLLA) scaffold compounded with borosilicate bioactive glasses (BBGs) endowing it with bioactive properties. Porous PLLA-BBG fibre mesh scaffolds were successfully prepared by the combination of wet spinning and fibre bonding techniques. Micro-computed tomography (μCT) confirmed that the PLLA-BBG scaffolds containing ≈25% of BBGs (w/w) exhibited randomly interconnected porous (58 to 62% of interconnectivity and 53 to 67% of porosity) with mean pore diameters higher that 100μm...

Within many institutional collections are skeletal and mummified human remains representing a part of our species' adaptation and evolution to various biocultural environments. Archaeologically recovered individuals come from deep into our past, and possess information that provides insight into population history, genetics, diet, health and other questions relevant to all living peoples. Academic concerns have been raised regarding the reinterment of these collections due to the rise of the international repatriation movement, the passage of various laws and implementation of institutional policies...
