INTRODUCTION/BACKGROUND: Xeroform(®) is a petrolatum-based fine mesh gauze containing 3% bismuth tribromophenate. Bismuth, similar to other metals, has antimicrobial properties. Xeroform(®) has been used for decades in burn and plastic surgery as a donor site dressing and as a covering for wounds or partial thickness burns. Despite this, the antimicrobial spectrum of Xeroform(®) remains largely unknown. We examined the in-vitro efficacy of Xeroform(®) against common burn pathogens using zone-of-inhibition methodology in a commercial research facility...

Cadaveric skin allograft is the current standard of treatment for temporary coverage of large burn wounds. Porcine xenografts are viable alternatives but undergo α-1,3-galactose (Gal)-mediated hyperacute rejection and are lost by POD 3 because of naturally occurring antibodies to Gal in primate recipients. Using baboons, we previously demonstrated that xenografts from GalT-KO swine (lacking Gal) provided wound coverage comparable with allografts with systemic immunosuppression. In this study, we investigate topical immunosuppression as an alternative to prolong xenograft survival...

Topographic features play a crucial role in the regulation of physiologically relevant cell and tissue functions. Here, an analysis of feature-size-dependent cell-nanoarchitecture interactions is reported using an array of scaffolds in the form of uniformly spaced ridge/groove structures for engineering wound healing. The ridge and groove widths of nanopatterns are varied from 300 to 800 nm and the nanotopography features are classified into three size ranges: dense (300-400 nm), intermediate (500-600 nm), and sparse (700-800 nm)...

STUDY DESIGN: A retrospective review. OBJECTIVES: To evaluate the therapeutic efficacy of the triple layer closure technique to establish watertight sealing without diversion of lumbar drainage, in preventing persistent incidental subarachnoid-pleural fistula and other neurological complications related to excessive drainage of cerebrospinal fluid (CSF) after dural defect in transthoracic ossified posterior longitudinal ligament (OPLL) surgery. SUMMARY OF BACKGROUND DATA: CSF leakage into the pleural cavity leads to unfavorable conditions for natural healing of incidental durotomy due to the negative pressure environment of the pleural space and lack of wound healing around the bony cavity near the decompressed spinal cord...

INTRODUCTION: Post-operative wound infections after spinal surgery is a very serious problem, leading to a risk of significant morbidity which may even lead to prolonged hospitalization. Various treatment protocols have been recommended for debridement, antibiotic, and soft-tissue management, but with mixed results. However, the risk of morbidity is still high with these treatment options. Vacuum-assisted closure (VAC) system has been gaining popularity recently in the management of subacute, acute, and chronic wounds...

BACKGROUND: Primary dural repair in ossification of posterior longitudinal ligament (OPLL) surgery via anterior is challenging because of limited space. Based on several years of our experiences, we present our concept for addressing cerebrospinal fluid (CSF) leakage following dural tear during anterior OPLL surgery. METHODS: We reviewed the medical records of 65 patients who underwent anterior OPLL surgery from 2003 to 2014. We included 7 patients whose operation records described dural tear followed by CSF leakage...

Polyurethane (PU)-based dressing foams have been widely used due to their excellent water absorption capability, optimal mechanical properties, and unequaled economic advantage. However, the low bioactivity and poor healing capability of PU limit the applications of PU dressings in complex wound healing cases. To resolve this problem, this study was carried out the hybridization of bioactive silica nanoparticles with PU through a one-step foaming reaction that is coupled with the sol-gel process. The hybridization with silica did not affect the intrinsically porous microstructure of PU foams with silica contents of up to 10wt% and where 5-60nm silica nanoparticles were well dispersed in the PU matrix, despite slight agglomerations...

The pleotropic cytokine interleukin-6 (IL-6) is implicated in retinal ganglion cell (RGC) survival and degeneration, including that associated with glaucoma. IL-6 protects RGCs from pressure-induced apoptosis in vitro. However, it is unknown how IL-6 impacts glaucomatous degeneration in vivo. To study how IL-6 influences glaucomatous RGC axonopathy, accompanying glial reactivity, and resultant deficits in visual function, we performed neural tracing, histological, and neurobehavioral assessments in wildtype (B6;129SF2/J; WT) and IL-6 knock-out mice (B6;129S2-IL6(t)(m1kopf)/J; IL-6-/-) after 8 weeks of unilateral or bilateral microbead-induced glaucoma (microbead occlusion model)...

BACKGROUND: Split-thickness skin grafting (STSG) is a time-tested technique in wound cover, but many factors lead to suboptimal graft take. Role of custom-made negative-pressure wound therapy (NPWT) is compared with conventional dress in the integration of STSG and its cost is compared with widely used commercially available NPWT. MATERIALS AND METHODS: This is a parallel group randomised control study. Block randomisation of 100 patients into one of the two groups (NPWT vs...

In the seed beetle Callosobruchus maculatus, the male intromittent organ is covered in sharp spines that pierce the female copulatory tract wall during mating. Although the fitness consequences of traumatic mating are well studied in this species, we know much less about how the male and female genitalia interact during mating. This is partly due to the fact that genital interactions occur primarily inside the female, and so are difficult to observe. In this study, we use X-ray micro-CT scanning to examine the proximate mechanisms of traumatic mating in C...

We present the case of a 91-year-old woman lived alone at her home with two domestic dogs, that is,, a Labrador Retriever and a Staffordshire Bull Terrier and found dead. The investigation of the scene revealed that the Bull Terrier's jawbone and chest were covered with blood. The autopsy revealed multiple, histologically confirmed, life-threatening skin and bone lacerations without scavenging marks. The punctures and tearing of each of the wounds on the skin were compatible with bites. A left humeral fracture and multiple fractures of the right facial bones were observed...

Diabetic foot ulcer (DFU) is a frequent complication in diabetic patients, occurring in up to 25% of those affected. Among the treatments available to clinicians, the use of bioengineered skin substitutes is an attractive alternative. Artificial dermis functions as a matrix, covering the wound and supporting healing and reconstruction of the lost tissue. This study was aimed at reviewing the use of five regeneration matrices (namely, Integra, Nevelia, Matriderm, Pelnac, and Renoskin) as reported by clinical trials...

The aim of this retrospective study was to document secondary wound healing and outcome in 20 cattle that had undergone digit amputation at the level of the distal metaphysis of the first phalanx between April 2009 and June 2015. The surgical technique for amputation was simple and fast, and granulation tissue covered the stump of the first phalanx 9 to 30 days postoperatively. Complications associated with wound healing were seen in 7 animals and in 3, a second surgery was required; all 20 cattle were discharged from the clinic...

In harvesting skin to cover the defect caused by a burn, a second wound is created, the donor site wound. We propose an alternative method to manage the donor site: taking a split-thickness skin graft (STSG) from a donor site adjacent to the burn wound to be treated, and meshing at a 3:1 ratio to cover both sites at once. The main objective of this study is to evaluate the effectiveness of covering both burn wound and adjacent donor site with the same STSG in elderly and bedridden patients. We retrospectively reviewed the medical records of 6 patients over 60 years old or/and bedridden presenting with a small burn wound who underwent STSG of both burn wound and adjacent donor site between April 2016 and November 2016 in the Department of Plastic Surgery and Burn Treatment at Percy Military Hospital (France)...

BACKGROUND: Current guidelines recommend blood cultures in skin and soft-tissue infection (SSTI) patients only with signs of systemic toxicity and wound cultures for severe purulent infections. Our objectives were to determine: 1) blood and wound culture yields in patients admitted with SSTIs; 2) whether injection drug users (IDUs) and febrile patients had higher blood culture yields; and 3) whether blood and wound cultures grew organisms sensitive to typical SSTI empiric antibiotics...

Chronic wounds represent a serious problem in daily medical routine requiring improved wound care. Silk of the domesticated silkworm (B. mori) has been used to form a variety of biomaterials for medical applications. We genetically engineered B. mori to produce silk functionalized with growth factors to promote wound healing. In this study FGF-, EGF-, KGF-, PDGF- or VEGF-functionalized silk membranes were compared to native B. mori silk membranes without growth factors for their ability to support wound healing...

BACKGROUND: Extraarticular distal tibial fractures are among the most challenging fractures encountered by an orthopedician for treatment because of its subcutaneous location, poor blood supply and decreased muscular cover anteriorly, complications such as delayed union, nonunion, wound infection, and wound dehiscence are often seen as a great challenge to the surgeon. Minimally invasive plate osteosynthesis (MIPO) and intramedullary interlocking nail (IMLN) are two well-accepted and effective methods, but each has been historically related to complications...
