Background: Burn wounds are commonly encountered in clinical settings and the management aims at the prevention of mortality and morbidity due to disability. The platelet-rich plasma (PRP) is blood-derived biomaterial that is enriched with growth factors and cytokines that facilitate wound healing. The PRP has proven its efficacy in various other wounds, but its role in post-burn raw areas and graft take has not been validated.

Hypertrophic scar (HTS) remains a comorbidity of burn injury, often requiring split thickness skin grafting (STSG) and resulting in symptomatic HTS at grafted sites and STSG donor sites (DS). Literature supports the use of ablative fractional CO2 laser (FLSR) to treat HTS, however many trials lack of control sites and tissue-level examinations. Given the widespread adoption of FLSR for HTS, delegation of non-treated scar sites for the sake of randomized controlled trial (RCT) is troubling for many clinicians.

Burn injuries in the paediatric population are common and account for a substantial proportion of hospital attendances, leading to a growing focus on optimising wound care to enhance healing, reduce discomfort and minimise the need for frequent dressing changes. Traditional dressings for superficial burns in children have inherent limitations that may hinder these goals. Biobrane (Dow Hickman/Bertek Pharmaceuticals, Sugar Land, TX), a semi-permeable silicone device embedded with a nylon mesh and a porcine-derived collagen matrix, offers a promising alternative with advantages such as improved wound healing, reduced pain and fewer dressing changes.

The urgent need to enhance the early vascularization of dermal substitutes to improve their repair efficiency in skin defect wound presents a significant challenge. This study investigated the impact of dual gene-activated scaffolds (DGAS-M), which combined nanocomposite particles (NPs) encapsulating plasmid DNA (pDNA) of VEGF and aFGF, with the aim of enhancing early vascularization and vascular maturation. In this study, we used the liposomes to encapsulate pDNA and loaded on PLGA knitted mesh-reinforced collagen/chitosan scaffolds (PLGAm/CCS) to prepare DGAS-M.

Background: Split-thickness skin grafts (STSG) over tendon or bone often fail. In such cases, an attempt to create a neo-dermis or restore a dermal-like covering is indicated. This study compared the outcomes of dermal regeneration template (DRT) use in lower extremity (LE) wound closure when combined with STSG procedures.
