Major reconstructive surgery may be extensive and prolonged, and it may cause edema and compromise the flap pedicle if closed under tension. Glycerol-preserved skin allograft (GPA) can provide a means for tension-free closure and temporary cover of the wound. Seven years of analysis on GPA used in conjunction with major reconstruction was undertaken to highlight its indications, results, and outcomes. Forty-seven patients were included, aged between 9 and 73 years. Majority of patients had reconstruction following tumor resection and trauma. The main indication for use of GPA was temporary, loose cover of the wound in 44% of cases; flap pedicle protection in 31% of cases; donor site wound cover in 10%; flap monitoring in one case; and management of flap-related complications in 6% of cases. Free flap reconstruction was performed in 72% of cases. In conclusion, GPA is a useful adjunct in reconstructive surgery. It can be used temporarily to allow tension-free wound closure, as well as to protect the flap pedicle until edema subsides and the pedicle becomes stable. This latter approach allows secondary wound closure and good esthetic outcome.

"It forms a mechanical barrier against fluid, protein, and electrolyte losses, thus preventing tissue desiccation and also microbial invasion. A skin allograft can also be used as a “take” test prior to autologous skin grafting [36, 37]. "
[Show abstract][Hide abstract] ABSTRACT: The escalating incidence of diabetic mellitus has given rise to the increasing problems of chronic diabetic ulcers that confront the practice of medicine. Peripheral vascular disease, neuropathy, and infection contribute to the multifactorial pathogenesis of diabetic ulcers. Approaches to the management of diabetic ulcers should start with an assessment and optimization of the patient's general conditions, followed by considerations of the local and regional factors. This paper aims to address the management strategies for wound bed preparation in chronic diabetic foot ulcers and also emphasizes the importance of preventive measures and future directions. The "TIME" framework in wound bed preparation encompasses tissue management, inflammation and infection control, moisture balance, and epithelial (edge) advancement. Tissue management aims to remove the necrotic tissue burden via various methods of debridement. Infection and inflammation control restores bacterial balance with the reduction of bacterial biofilms. Achieving a moist wound healing environment without excessive wound moisture or dryness will result in moisture balance. Epithelial advancement is promoted via removing the physical and biochemical barriers for migration of epithelium from wound edges. These systematic and holistic approaches will potentiate the healing abilities of the chronic diabetic ulcers, including those that are recalcitrant.

[Show abstract][Hide abstract] ABSTRACT: Wound bed preparation has been performed for over two decades, and the concept is well accepted. The 'TIME' acronym, consisting of tissue debridement, infection or inflammation, moisture balance and edge effect, has assisted clinicians systematically in wound assessment and management. While the focus has usually been concentrated around the wound, the evolving concept of wound bed preparation promotes the treatment of the patient as a whole. This article discusses wound bed preparation and its clinical management components along with the principles of advanced wound care management at the present time. Management of tissue necrosis can be tailored according to the wound and local expertise. It ranges from simple to modern techniques like wet to dry dressing, enzymatic, biological and surgical debridement. Restoration of the bacterial balance is also an important element in managing chronic wounds that are critically colonized. Achieving a balance moist wound will hasten healing and correct biochemical imbalance by removing the excessive enzymes and growth factors. This can be achieved will multitude of dressing materials. The negative pressure wound therapy being one of the great breakthroughs. The progress and understanding on scientific basis of the wound bed preparation over the last two decades are discussed further in this article in the clinical perspectives.

[Show abstract][Hide abstract] ABSTRACT: The use of glycerol preserved skin allograft (GPA) became a main stay in burn treatment. However, harvesting of cadaveric skin is not yet legalized in many countries including Egypt.
To estimate the feasibility of using skin harvested from body contouring procedures as a source of GPA and its clinical efficacy.
Skin harvested from body contouring procedures done in Al-Azhar university hospitals was preserved by glycerolization and used in management of burn and complicated wounds.
In the period between February 2012 and February 2013 skin was harvested from 24 abdomenoplasty cases, 6 bilateral breast reduction cases, and 1 case of thigh lift done in Al-Azhar university hospitals. This yielded about 22,000cm(2) of skin preserved by glycerolization. This GPA was used in 15 excised burn wounds, in 9 cases of chronic burn wounds, and in 6 complicated wounds. Partial graft loss occurred in 3 cases and total graft loss occurred in 1 case.
The glycerolized full-thickness skin harvested from body contouring procedures is clinically effective in burn and wound management. In the presence of regional coordination, it can serve as an abundant source for skin banking in where cadaveric skin use is not legalized.
