REVIEW
Linda Nazarko
Dead and devitalised tissue interferes with the process of wound healing. Debridement is a natural process that occurs in all wounds and is crucial to healing; it reduces the bacterial burden in a wound and promotes effective inflammatory responses that encourage the formation of healthy granulation tissue (Wolcott et al, 2009). Wound care should be part of holistic patient care. Recent advances in debridement techniques include: biosurgery, hydrosurgery, mechanical debridement, and ultrasound. Biosurgery and mechanical debridement can be practiced by nonspecialist nurses and can be provided in a patient's home, thus increasing the patient's access to debridement therapy and accelerating wound healing...

BACKGROUND: Articular cartilage has minimal endogenous ability to undergo repair. Multiple chondral restoration strategies have been attempted with varied results. QUESTIONS/PURPOSES: The purpose of our review was to determine: (1) Does articular chondrocyte transplantation or matrix-assisted articular chondrocyte transplantation provide better patient-reported outcomes scores, MRI morphologic measurements, or histologic quality of repair tissue compared with microfracture in prospective comparative studies of articular cartilage repair; and (2) which available matrices for matrix-assisted articular chondrocyte transplantation show the best patient-reported outcomes scores, MRI morphologic measurements, or histologic quality of repair tissue? METHODS: We conducted a systematic review of PubMed, CINAHL, and MEDLINE from March 2004 to February 2014 using keywords determined to be important for articular cartilage repair, including "cartilage", "chondral", "cell source", "chondrocyte", "matrix", "augment", "articular", "joint", "repair", "treatment", "regeneration", and "restoration" to find articles related to cell-based articular cartilage repair of the knee...

INTRODUCTION: The open abdominal (OA) approach is a management strategy used in the most severely injured trauma patients. In addition to the morbidity and mortality, a major challenge is the gradual development of dense adhesions that make reoperations progressively more difficult. This randomized, prospective, proof-of-concept study was conducted to determine the effect of carboxymethylcellulose sodium hyaluronate adhesion barrier (CMHAB; Seprafilm, Genzyme Biosurgery, Bridgewater, NJ) on abdominal adhesions and wound characteristics in trauma open abdomens...

Osteoarthritic (OA) knee pain can be successfully treated with hylan G-F 20 (Synvisc, Sanofi Biosurgery, Cambridge, MA) with few local adverse events. However, a few studies have identified hyaluronate positive (HA+) granulomas in the synovial tissue of patients treated with hylan G-F 20 raising the question of their relationship and clinical significance. To understand the potential relationship of HA+ granulomas with the occurrence of acute local reactions (ALRs), we evaluated the synovial tissue of OA patients undergoing total knee replacement that had previously been treated with hylan G-F 20 (n = 101) or had not been treated (n = 20)...

Vesicovaginal fistula (VVF), commonly caused by prolonged obstructed labor, is one of the worst complications of childbirth and poor obstetric care in the developing world. We investigated the clinical efficacy and outcome of technical modifications of the current transperitoneal supravesical technique for supratrigonal and complex vesicovaginal fistula. We studied a total of 20 patients with iatrogenic supratrigonal and complex vesicovaginal fistula following obstetric trauma and hysterectomy. All patients underwent a modified transabdominal technique: the modifications consisted of passing a Foley catheter through the fistulous opening, inflating the balloon, and applying traction on the catheter to provide effective anchorage and to minimize the oozing from the cystotomy edges...

New therapeutic approaches for wound treatment are evolving. Non healing wounds in oncology and after trauma may be cured by a novel technique of tissue augmentation with soft tissue fillers. The principle resides in filling the wound with collagen filler in order to seal the defect and promote healing. Successful angiogenesis forms the basis of tissue filler survival and determines the outcome of the healing process. During this study, basic data about endothelial cell invasion into collagen-made substratum was collected that could be used for neoangiogenesis studies in tissue augmentation techniques for large wound defect treatment...

Surgeons in abdominal and gynecological fields have pioneered the use of Seprafilm (a chemically modified sodium hyaluronate/carboxymethylcellulose absorbable adhesion barrier, Genzyme Biosurgery, Cambridge, MA, USA) to prevent adhesion but its use outside these specialties is not well documented. The authors have used Seprafilm for craniectomy closure in several patients as a dural substitute and anti-adhesion barrier. During emergent craniectomy, the dura mater is reapproximated and a layer of Seprafilm is placed over the dura as an onlay and anti-adhesion barrier...

OBJECTIVES: Arteriovenous fistula (AVF) is the preferred type of vascular access for hemodialysis to treat end-stage renal disease. A high proportion of AVF are never used for dialysis because the vein fails to mature adequately. We have previously described the safety and feasibility of Vascugel (Genzyme BioSurgery, Cambridge, Mass) (allogeneic aortic endothelial cells in a gelatin matrix) when placed around the anastomotic and venous outflow sites of AVFs (Vascular intimal Hyperplasia: Extending Arterial and venous patency, Limiting vascular Trauma, and inhibiting Hyperplasia while re-establishing vascular health [V-HEALTH] clinical study)...

Postsurgical adhesion formation is an important clinical problem within all surgical specialties. In gynecology, adhesions resulting from gynecologic procedures are a major clinical, social, and economic concern because they may result in pelvic pain, infertility, or bowel obstruction. In addition, it may lead to additional surgery to resolve the adhesion-related complications. This review evaluates the available evidence regarding the effectiveness of various strategies for reducing postsurgical adhesions...

Current autologous fat grafting technique suffers from the drawbacks of donor site morbidity and, more importantly, significant resorption of the grafted fat. Adipose tissue engineering using adult human stem cells has been found to overcome the shortcomings of autologous fat grafting in reconstructing facial defects. Mesenchymal stem cells that can self-renew and differentiate into mature adipocytes have been used to generate adipose tissue, in both in vitro and in vivo cell transplantation studies. However, long-term maintenance of the shape and dimension of the produced adipose tissue remains a challenge, even in tissue engineering with cell transplantation...

The face distinguishes one human being from another. When the face is disfigured because of trauma, tumor removal, congenital anomalies, or chronic diseases, the patient has a strong desire for functional and esthetic restoration. Current practice of facial reconstruction using autologous grafts, synthetic fillers, and prostheses is frequently below the surgeon's and patient's expectations. Facial reconstruction is yet to take advantage of recent advances in seemingly unrelated fields of stem cell biology, chemical engineering, biomaterials, and tissue engineering...

Lucilia sericata maggots are used world-wide in biosurgery for the medical treatment of nonhealing wounds because they ingest necrotic tissues and significantly promote healing. To gain further insight into interdependencies between ecological adaptation and molecular evolution of innate immunity in Diptera, we used the suppression subtractive hybridization method to screen for genes that are differentially expressed in response to septic wounding of sterile second instar larvae of L. sericata. This approach resulted in the identification of 65 novel Lucilia genes including potential signalling proteins (e...

Maggot therapy, also known as biosurgery, is an ancient method for the healing of chronic infected wounds. Although clinicians have reported on the beneficial activities of the Lucilia sericata larvae that have been used for healing chronic wounds, the selectivity of this therapy against the different pathogenic micro-organisms that are found in chronic wounds has never been analysed. In the present study, we have investigated the in vitro activities of larval excreta/secreta both against selected bacterial strains that frequently occur in chronically infected wounds, and against bacteria isolated directly from the larvae and their excreta/secreta...
