Bilateral internal thoracic artery (BITA) grafting may be associated with a higher risk of postoperative deep sternal wound infection than monolateral internal thoracic artery grafting due to a limited blood supply to the thoracic chest wall. Because preliminary studies suggest negative pressure wound therapy (NPWT) may reduce the risk of infection, a retrospective chart review of 129 patients who underwent BITA between February 2003 and October 2014 was conducted. Of those, 21 patients received NPWT for 5 days immediately following surgery and the incisions of 108 patients were covered with a conventional gauze dressing...

Acne vulgaris treatments usually cause sensitivity, teratogenicity and bacterial resistance. Investigations of others therapeutic techniques, such as phototherapy, is highly relevant. Thus, we compared the effectiveness of two Acne vulgaris treatments in adolescents: peeling with salicylic acid and phototherapy. Teens were randomly divided in: group I, treatment with salicylic acid peels (10 %) and group II, treatment with phototherapy (blue LED and red laser lights). Photographs were taken before and after ten sessions of each treatment, carried out weekly, and compared...

For normal embryonic development/morphogenesis, cell migration and homing are well-orchestrated and important events requiring specific cellular mechanisms. In diseases such as cancer deregulated cell migration represents a major problem. Therefore, numerous efforts are under way to understand the molecular mechanisms of tumor cell migration and to generate more efficient tumor therapies. Cell migration assays are one of the most commonly used functional assays. The wound-healing assay or the Boyden chamber assay are variations of these assays...

BACKGROUND: Giant Cell Tumor is considered a benign, local and aggressive tumor. Although considered a benign bone tumor, it is still the subject of discussion and research because of the associated local bone destruction, as well as high rates of recurrence and distant metastases. Options are being developed for both surgical techniques and adjuvant therapies. AIMS: The present study evaluated the administration of cryotherapy via a pressurized-spray technique in giant cell tumors of the bone...

We demonstrate that it is possible to use a nonabsorbable mesh for abdominal wall reconstruction after total wound rupture and successfully split-skin graft directly on the mesh. Sufficient granulation tissue formation prior to skin grafting was obtained with long-term use of negative pressure wound therapy (NPWT).

The use of live attenuated intravesicular Bacillus Calmette-Guerin (BCG) therapy is a generally accepted safe and effective method for the treatment of superficial transitional cell carcinoma (TCC) of the bladder. Although rare, < 5% of patient's treated with intravesicular BCG therapy may develop potentially serious complications, including localized infections to the genitourinary tract, mycotic aneurysms and osteomyelitis. We present here a case of a 63-year-old male who developed left coronary and multiple peripheral M...

BACKGROUND: Postburn axillary contractures are common and significantly impact quality of life. Simple release combined with split thickness skin grafting necessitates a donor site, requires immobilization, and may result in poor functional outcome. Common methods of adjacent tissue rearrangement are not well designed to treat broad linear contractures. Flaps from the back, flank, or arm can be used, but may come with significant donor site morbidity. We demonstrate the use of the STARplasty, a novel adjacent tissue rearrangement initially developed to treat neosyndactyly, as a useful reconstructive option for the release of Kurtzman type 1 posterior or anterior axillary contractures...

We assessed wound healing in patients on hemodialysis (HD) with critical limb ischemia (CLI). This study enrolled 267 patients (including 120 patients on HD and 147 patients not on HD) who underwent endovascular therapy (EVT) for CLI. The primary endpoint was wound-healing rate at two years. Secondary endpoints were time to wound healing, wound recurrence rate, and limb salvage at two years. The percentage of male and young patients was higher in the HD patients (p < 0.01). A lower patency of the pedal arch after EVT was observed frequently in HD patients (p < 0...

Lung fibrosis results from the cumulative effect of dysfunctional wound repair involving multiple cell types, including fibroblasts, epithelial cells and macrophages responding to an array of soluble and matrix mediated stimuli. Recent studies have shown that a tyrosine kinase inhibitor that targets FGF, VEGF and PDGF receptors can slow the rate of decline in pulmonary function in patients with idiopathic pulmonary fibrosis. However, each of these growth factor families is comprised of multiple ligands and receptors with pleiotropic activities on different cell types such that their broad inhibition might have both pro-fibrotic and anti-fibrotic effects, limiting the potential therapeutic efficacy...

: It is difficult to completely resect huge anterior chest wall keloids and then close the wound directly. We report here our retrospective analysis of our case series of patients with such keloids who underwent reconstruction with internal mammary artery perforator (IMAP) pedicled propeller flaps and then received postoperative high-dose-rate superficial brachytherapy. METHODS: All consecutive patients with large/severe keloids on the anterior chest wall who underwent keloid resection followed by reconstruction with IMAP-pedicled propeller flaps and then high-dose-rate superficial brachytherapy in our academic hospital were identified...

There is a growing interest in the development and evaluation of therapeutic agents that improve the cosmetic appearance of scars. Existing nonhuman animal models to study scarring, while valuable, have well-acknowledged limitations, as it is accepted that the biology of human scarring differs significantly from scarring in other species. Moreover, human clinical trials of scarring require large numbers of subjects to achieve statistical power and are plagued by inherent intersubject variability because of the complex nature of wound healing in human beings...

Acinetobacter baumannii is a gram-negative, non-motile bacterium that, due to its multidrug resistance, has become a major nosocomial pathogen. The increasing number of multidrug resistant (MDR) strains has renewed interest in phage therapy. The aim of our study was to assess the effectiveness of phage administration in Acinetobacter baumannii wound infections in an animal model to demonstrate phage therapy as non-toxic, safe and alternative antibacterial remedy. Using classical methods for the study of bacteriophage properties, we characterized phage vB-GEC_Ab-M-G7 as a dsDNA myovirus with a 90 kb genome size...

A meta-analysis was conducted to estimate the risk of wound-healing complications in patients who treated with neoadjuvant-adjuvant bevacizumab in various oncological indications. We searched PUBMED, EMBASE and the Cochrane Library through June 2016 to identify randomized controlled trials of bevacizumab and wound-healing complications. Seven RCTs studies involving 5,147 participants were included in the analysis. Compared with routine therapy, bevacizumab increased the incidence of wound-healing complications for various cancers...

High-mobility group AT-hook2 (HMGA2), involved in epithelial mesenchymal transition (EMT) process, has a pivotal role in lung cancer metastasis. Lung cancer therapy with HMGA2 suppressing small interfering RNA (siRNA) has been introduced recently while doxorubicin (DOX) has been used as a frequent cancer chemotherapy agent. Both reagents have been faced with obstacles in clinic which make them ineffective. NanoParticles (NPs) provided a platform for efficient co delivery of the anticancer drugs. The aim of this study was production and in vitro characterization of different pharmacological groups (siRNA, DOX or siRNA-DOX) of carboxymethyl dextran thrimethyl chitosan nanoparticles (CMDTMChiNPs) on cytotoxicity, gene expression, apoptosis and migration of metastatic lung cancer cell line (A-549)...

PURPOSE: Corneal collagen cross-linking (CXL) is associated with massive cellular damage, the long-term clinical consequences of which have still to be elucidated. In this study, we seek to determine whether matrix-based regenerating agent (RGTA) therapy has a positive influence on stromal regeneration after CXL. METHODS: Twelve New Zealand white rabbits were randomly divided into 2 groups of 6. CXL of the right cornea was performed in both groups, followed by topical corneal application of one drop of vehicle or one drop of RGTA...

A wide range of etiologies can cause hemifacial spasm (HFS), including infection. In this case report, a 44-year-old woman developed HFS and was explored surgically 7 years later. No abnormalities were found. Afterward, treatment of a surgical wound infection with an oral cephalosporin resulted in a temporary HFS remission that had never occurred previously. This antibiotic experience prompted further workup for an underlying infection, which ultimately led to diagnosis of Lyme disease. Presentation of HFS due to Lyme disease has not been reported...

We report a case of posttraumatic skin and soft-tissue infection in a patient with a left thigh wound after a traffic accident. Pseudomonas fulva was isolated from a wound aspirate and was identified to the species level by Maldi-tof. The patient responded to drainage, debridement of wound, and two weeks of intravenous antibiotic therapy. Follow-up after 3 weeks was satisfactory with healthy cover of the injured area.

We herein report two cases of perigraft effusion mimicking graft infection after debranching thoracic endovascular repair for an anastomotic pseudoaneurysm of the distal ascending aorta. Both patients presented with a bulging tumor on the sternum. Enhanced computed tomography showed no endoleak, but extension of periprosthetic graft fluid to a subcutaneous sternal wound was present. We suspected a deep sternal wound infection; however, cultures of débrided tissues were negative. After drainage of the subcutaneous fluid or negative pressure wound therapy, both patients were doing well without recurrence of effusion...

We observed that radially stretching cell monolayers at a low level (3%) increases the rate at which they migrate to close a gap formed by in vitro injury. Wound healing has been shown to accelerate in vivo when deformations are topically applied, for example, by negative pressure wound therapy. However, the direct effect of deformations on cell migration during gap closure is still unknown. Thus, we have evaluated the effect of radially applied, sustained (static) tensile strain on the kinematics of en mass cell migration...
