Jérôme Patry, Virginie Blanchette
Enzymatic debridement with collagenase is a technique that is commonly used in clinical practice. This systematic review examines the effect of collagenase on all kinds of wounds, compared to an alternative therapy, on wound healing, wound bed characteristics, cost-effectiveness and the occurrence of adverse events. We conducted a systematic literature search on available literature in Cochrane databases, MEDLINE, EMBASE and CINAHL. Two investigators independently assessed the titles and abstracts of all randomised controlled trials obtained involving collagenase of all kinds of wounds based on inclusion criteria...

Liposuction is the one of the most frequently performed cosmetic operations and usually has an easy recovery, with a reportedly low overall complication rate. Here, we report the case of a 60-year-old woman with type II diabetes mellitus and a previous burn injury of the abdomen who underwent abdominal liposuction and subsequently developed necrotising fasciitis. Following radical debridement, systemic antibiotic administration, negative pressure wound therapy and hyperbaric oxygen therapy, the wound healed completely...

INTRODUCTION: Human placental membranes (hPMs) have a long history in treating burns and wounds. The composition of hPMs includes structural matrix, growth factors, and neonatal cells, all of which contribute to their regenerative potential. However, most hPM products are devitalized after dehydration and irradiation. We compared the functionality of single-layer viable cryopreserved human amniotic membrane (vCHAM) with multilayer devitalized dehydrated human amnion/chorion membrane (dHACM) in wound-relevant models to determine the effect of different processing methods on hPMs...

Perception of the adipose tissue has changed dramatically over the last few decades. Identification of adipose-derived stem cells (ASCs) ultimately transformed paradigm of this tissue from a passive energy depot into a promising stem cell source with properties of self-renewal and multipotential differentiation. As compared to bone marrow-derived stem cells (BMSCs), ASCs are more easily accessible and their isolation yields higher amount of stem cells. Therefore, the ASCs are of high interest for stem cell-based therapies and skin tissue engineering...

Significance: Rapid recruitment and activation of macrophages may accelerate wound healing. Such accelerated healing was observed in wounds and burns of experimental animals treated with α-gal nanoparticles. Recent Advances: α-Gal nanoparticles present multiple α-gal epitopes (Galα1-3Galβ1-4GlcNAc-R). α-Gal nanoparticles applied to wounds bind anti-Gal (the most abundant antibody in humans) and generate chemotactic complement peptides, which rapidly recruit macrophages. Fc/Fc receptor interaction between anti-Gal coating the α-gal nanoparticles and recruited macrophages activates macrophages to produce cytokines that accelerate healing...

Infections caused by Staphylococcus aureus were treated by methicillin, but about 95% of S. aureus has been resistance to methicillin, both in the community and hospitals and are increasing day by day. MRSA produces altered penicillin binding protein, PBP2a, due to the expression of mecA gene. Some strains of both the MRSA and MSSA carry PVL gene. This cross sectional observational study was conducted to detect the molecular-characterization of methicillin resistant Staphylococcus aureus (MRSA) and carried out in the Department of Microbiology, Mymensingh Medical College from July 2014 to December 2015...

Mucormycosis is a rare opportunistic fungal infection that can implicate cranial sinuses, brain, lungs, gastrointestinal tract and skin. Although it can occur in patients with competent and incompetent immunity such as patients with diabetes mellitus, lymphoma, leukemia and burns, but it has an aggressive, malignant and lethal course in patients with incompetent immunity. To enforce the importance of burn in patients with underlaying diseases such as diabetes, we are going to report a rare case of diabetic burnt patient complicated by right upper extremity myocutaneous mucormycosis...

Mesenchymal stem cells (MSCs) are bone marrow-derived non-hematopoietic progenitor cells. MSCs are able to differentiate into various types of cells, including chondrocytes, adipocytes, osteocytes, myocytes, endothelial cells, and keratinocytes. There is increasing evidence that MSCs might be located external to the vasculature, and that perivascular cells in the skin, generally called as "pericytes", might include MSCs. It has been suggested that MSCs localized around blood vessels might migrate into wounds and contribute to the restoration of injured tissues...

Mucor fungus infection is a rare opportunistic infection, rapidly progressive and often fatal in immunocompromised patients, or in patients with chronic debilitating diseases. We report six cases of trauma patients with mucormycosis. Three had severe thermal burns, one of them with a medical history of diabetes mellitus. The other three patients suffered from severe soft tissue injuries caused by traffic accidents. In all cases there had been spontaneous exposure and contact of the wounds with soil. During hospitalization, fungi cultures and/or biopsies of all wounds were performed and all resulted positive...

Increasing antimicrobial resistance requires the development of novel materials and approaches for treatment of various infections. Utilization of photodynamic therapy represents an advanced alternative to antibiotics and metal-based agents. Here, we report the fabrication of electrospun material that possesses benefits of both topical antimicrobial and photodynamic therapies. This material combines chitosan, as a biocompatible polymer, and a second generation photosensitizer. The incorporation of photosensitizer doesn't affect the material morphology and its nearly uniform distribution in fibers structure was observed by confocal Raman microscopy...

The wound healing includes non-healing and overhealing of the wounds. The results of wound healing are well known by people such as non-healing of the diabetic ulcer or hypertrophic scar after deep burn. In this issue, three papers involve in wound healing, one about autologous adipose-derived mesenchymal stem cells injected into wound or scar of rabbit ear, one about severe hypoxia and hypoalbuminemia inducing human hypertrophic scar derived fibroblast apoptosis in vitro, and another about the dysfunction of protein kinase B/mammalian target of rapamycin signaling pathway contributing to the pathophysiological characteristics of diabetic skin and non-healing wound...

Mice engrafted with human CD34(+) hematopoietic stem and progenitor cells (CD34(+) -HSPCs) have been used to study human infection, diabetes, sepsis, and burn, suggesting that they could be highly amenable to characterizing the human inflammatory response to injury. To this end, human leukocytes infiltrating subcutaneous implants of polyvinyl alcohol (PVA) sponges were analyzed in immunodeficient NSG mice reconstituted with CD34(+) -HSPCs. It was reported that human CD45(+) (hCD45(+) ) leukocytes were present in PVA sponges 3 and 7 days postimplantation and could be localized within the sponges by immunohistochemistry...

Mucormycosis is a rare, rapidly progressive and often fatal fungal infection. The rarity of the condition lends itself to unfamiliarity, delayed treatment, and poor outcomes. Diagnosis of fungal infections early enough to enable appropriate treatment occurs in less than half of affected patients. A 56-year-old male with a history of diabetes mellitus II, hepatitis C, and intravenous drug abuse was involved in a rollover motor vehicle accident. He sustained circumferential partial and full-thickness burns to his lower extremities with 20% BSA burns...
