BACKGROUND: Surgical site infections (SSIs) are one of the most troublesome complications after foot and ankle surgery. Previous literature has emphasized the significance of appropriate timing of antibiotic prophylaxis. However, the optimal timing of antibiotic prophylaxis for SSI prevention is still inconclusive. Our study aimed to investigate the optimal timing of antibiotic administration and to elucidate the risk factors for SSIs in foot and ankle surgery. METHODS: A retrospective review of 1933 foot and ankle procedures in 1632 patients from January 1, 2011, through August 31, 2015, was performed...

PURPOSE: Nonexudative (dry) age-related macular degeneration (AMD), a leading cause of blindness in the elderly, is associated with the loss of retinal pigmented epithelium (RPE) cells and the development of geographic atrophy, which are areas devoid of RPE cells and photoreceptors. One possible treatment option would be to stimulate RPE attachment and proliferation to replace dying/dysfunctional RPE and bring about wound repair. Clinical trials are underway testing injections of RPE cells derived from pluripotent stem cells to determine their safety and efficacy in treating AMD...

BACKGROUND: Among all procedures, surgical site infections (SSIs) in colorectal surgery continue to have the highest rate, accounting for 5%-45%. To prevent the bacterial colonization of suture material, which disables local mechanisms of wound decontamination, triclosan-coated sutures were developed. We assessed the effectiveness of triclosan-coated sutures used for skin closure on the rate of SSIs in colorectal cancer surgery. METHODS: Until August 2012, we used conventional methods for skin closure in colorectal cancer surgery at the Department of Gastroenterological Surgery, Fukuoka University Faculty of Medicine...

The aim of this work was to evaluate the antioxidant and hemolytic activities as well as the in vivo wound healing performance of a novel polysaccharide (FWEP) extracted from fenugreek (Trigonella foenum-graecum) seeds. The antioxidant activity was evaluated in vivo and in vitro using various assays. Results showed that FWEP exhibited strong antioxidant activities but no hemolytic activity was observed towards bovine erythrocytes. The application of FWEP hydrogel on the wound site in a rat model enhanced significantly wound healing activity and accelerated the wound closure after 14days of wound induction...

AIM: The aim of this study was to investigate the effects of compartment syndrome and timing of fasciotomy wound closure on surgical site infection (SSI) after surgical fixation of tibial plateau fractures. Our primary hypothesis was that SSI rate is increased for fractures with compartment syndrome versus those without, even accounting for confounders associated with infection. Our secondary hypothesis was that infection rates are unrelated to timing of fasciotomy closure or fixation...

Negative pressure wound therapy (NPWT) is widely used to treat many types of complex wounds, and the advent of the instillation and dwell time (NPWTi-d) technique has enhanced this system with the addition of automated treatment with topical solutions. In the field of vascular surgery, NPWT is utilized to help close wounds over underlying grafts; however keeping these wounds free of infection and avoiding large reoperation when infection occurs remains a challenge. In this case report we present a patient who required acute intervention for limb ischemia, with a large wound created in the groin for anastomosis of a prosthetic graft bypass...

INTRODUCTION: Epidermal grafting has several advantages over full-thickness or split-thickness grafts in the treatment of complex non-healing wounds. These include the low risk of donor site complications, minimal patient discomfort, and abstention from the operating room. Traditionally, the lack of reliable epidermal harvesting techniques has limited its clinical utilization. The development of an automated suction blister epidermal graft (SBEG) harvesting device may facilitate clinical utilization of this technique...

Neural-Wiskott Aldrich Syndrome Protein (N-WASP) is expressed ubiquitously, regulates actin polymerization and is essential during mouse development. We have previously shown that N-WASP is critical for cell-ECM adhesion in fibroblasts. To characterize the role of N-WASP in fibroblast for skin development, we generated a conditional knockout mouse model in which fibroblast N-WASP was ablated using the Cre recombinase driven by Fibroblast Specific Protein promoter (Fsp-Cre). N-WASP(FKO) (N-WASP(fl/fl); Fsp-cre) were born following Mendelian genetics, survived without any visible abnormalities for more than 1 year and were sexually reproductive, suggesting that expression of N-WASP in fibroblast is not critical for survival under laboratory conditions...

BACKGROUND: Diabetic foot ulcer (DFU) is a major complication of diabetes mellitus. Although previous studies have established that inflammation, ischemia and neuropathy contribute to the development of DFU, it is still an unmet medical need due to lack knowledge of cellular and molecular mechanisms associated with DFU. In the present study, we tested our hypothesis that subcutaneous application of human placental mesenchymal stem cells (PMSCs) can accelerate diabetic dermal wound healing by modulating immunoresponse...

OBJECTIVE To compare security of continuous intradermal suture lines closed by use of barbed suture with 3 end-pass configurations or without an end-pass configuration. SAMPLE 40 full-thickness, 4-cm-long, parasagittal wounds in canine cadavers. PROCEDURES Each continuous intradermal closure was terminated with 1 of 3 end-pass techniques or without an end-pass configuration (control group). A servohydraulic machine applied tensile load perpendicular to the long axis of the suture line. A load-displacement curve was generated for each sample; maximum load, displacement, stiffness, mode of construct failure, and load at first suture slippage at termination (ie, terminal end of the suture line) were recorded...

BACKGROUND: This study assessed the safety of the newly developed bridge-enhanced anterior cruciate ligament (ACL) repair (BEAR), which involves suture repair of the ligament combined with a bioactive scaffold to bridge the gap between the torn ligament ends. As the intra-articular environment is complex in its response to implanted materials, this study was designed to determine whether there would be a significant rate of adverse reaction to the implanted scaffold. HYPOTHESIS: The primary hypothesis was that the implanted scaffold would not result in a deep joint infection (arthrocentesis with positive culture) or significant inflammation (clinical symptoms justifying arthrocentesis but negative culture)...

This paper details the study of biodynamic excisional skin tension lines on the scalp and the development of a new flap technique for closure of scalp wounds. Recently, a study by this author, on pigskin, replicated whorls by placing tissue under rapid stretch using saline tissue expanders, by recreating rapid dermo-epidermal shear of skin - thereby concluding that the golden spiral pattern is nature's own pattern for rapid expansion. Given the relationship between tissue expansion and stretch has been shown to cause deformation gradients that have both elastic and growth factors, the author set out to test the hypothesis that a golden spiral pattern therefore would be more efficient at closing wounds under less tension when compared with standard semicircular rotational flap patterns...

INTRODUCTION: Despite the numerous advances in recent years, severe abdominal sepsis (with associated organ failure associated with infection) remains a serious, life-threatening condition with a high mortality rate. OA is a viable alternative to the previously used scheduled repeat laparotomy or continuous peritoneal lavage. The use of Negative Pressure Wound Therapy (NPWT) has been described as a successful method of management of the open abdomen. Adding instillation of saline solution to NPWT in a programmed and controlled manner, could offer the clinician an additional tool for the management of complex septic abdomen...

REVIEW
Matthew R Louis, Jesse D Meaike, Edward Chamata, Larry H Hollier
The care of pediatric patients requires special considerations that are often not addressed in the literature. Relatively straightforward tasks such as clinical evaluation, antibiotic use, splinting, wound closure, and care of simple burns become complicated in the pediatric population for several reasons. The authors seek to demystify some of these topics using the senior author's years of clinical experience treating pediatric patients by giving practical advice and general considerations when treating children...
