Wound infection following burn injury can be clinically challenging to manage. Its presence in a thermally compromised patient can detrimentally affect the ability of the wound to heal leading not only to wound progression but ultimately contribute to a large part of the economic health burden expenditure in the National Health Service. Despite meticulous wound care and infection control measures the colonisation of burn wounds by bacterial pathogens has and continues to be the case. There has been a growing interest in the use of antimicrobial applications when managing localised burn wound infections due to a constantly increasing number of antibiotic-resistant organisms. ⋯ We identified a significant difference in the UK burns services' approach to pseudomonas burn wound infections. Our literature review demonstrates that a daily dressing regime of 2.5-3% acetic acid is a well-tolerated treatment regime in burn patients and that it is in use in UK burns services. There are no current randomised controlled trials that evaluate the usage of acetic acid. The variation in usage suggests that there is scope for further study in order to develop evidence to generate a UK wide approach based on national standardised guidelines.

Implementation science is a useful tool to consider ways in which we can introduce improvements to burn services in low-and-middle income countries (LMICs), where the majority of the burden of burn injury is now experienced. This paper outlines the development of the Delivery Assessment Tool (DAT), a method for facilitating quality improvement in burn services in LMICs. We used a participatory approach that ensured that local clinicians and experts were fully involved in piloting the tool. ⋯ Education and training are key components of this work; both were provided by Interburns as part of on-going support for the clinical teams. At the end of the project a>19% improvement in scores was demonstrated using the final version of the DAT in both Nepal and Bangladesh; this achievement is remarkable given the continued difficulties in service provision where patient numbers far outstrip the resources available to care for them. As a result of this work, we have made a digital version of the tool available free of charge.

Frostbite is a severe thermal injury, which characterized by tissue necrosis with a high percentage of amputations, disability of patients. ⋯ The defining moments in the treatment of deep frostbite are timely diagnosis and complex treatment. With late admission surgical treatment, including reconstructive skin plastic surgery, becomes important.

Multicenter Study
A multicenter study analyzing the association of vitamin D deficiency and replacement with infectious outcomes in patients with burn injuries.
Vitamin D (25OHD) deficiency is associated with poor outcomes in intensive care populations. The primary objective of this 7-center study was to determine if 25OHD deficiency is associated with infectious outcomes in adult burn patients. Generalized linear mixed modeling was used to control for center effect, percent total body surface area burn (% TBSA), age, and presence of inhalation injury. ⋯ Deficient patients were more likely to have an infectious outcome (52.1% vs 36.0%, p = 0.002), acute kidney injury with renal replacement therapy (p = 0.009), less ventilator free days in the first 28 days (p < 0.001), and vasopressors (p = 0.01). After controlling for center, % TBSA, age, and inhalation injury the best model also included presence of deficiency (OR 2.425 [CI 1.206-4.876]), days until 25OHD supplement initiation (OR 1.139 [CI 1.035-1.252]), and choice of cholecalciferol over ergocalciferol (OR 2.112 [CI 1.151-3.877]). To the authors' knowledge, this is the first multicenter study to evaluate the relationship between 25OHD and infectious complications in burn patients.

Alu elements are retrotransposons related to epigenetic modifications. To date, the role of epigenetics in hypertrophic scars from burn remains unknown. Here, our aim was to examine the pathophysiology of hypertrophic scars from an epigenetic perspective. ⋯ Alu total methylation (mC) and the uCmC pattern were significantly lower, whereas uCuC was significantly higher, in hypertrophic scar tissues than in normal skin (p < 0.0001). Receiver operating characteristic analysis indicated that the uCmC and uCuC patterns are useful as hypertrophic scar DNA methylation markers after burn, with 91.30% sensitivity and 96.23% specificity and 100% sensitivity and 94.23% specificity, respectively. Our findings suggest that epigenetic modifications play a major role in hypertrophic scar pathogenesis, and may be the starting point for developing a novel technique for burn scar treatment.
