Background Burns are one of the major traumas that may affect older individuals. The purpose of this study was to investigate the epidemiological and clinical characteristics of geriatric burns at a major center in south-west China. Methods This retrospective study was conducted at the Institute of Burn Research, Southwest Hospital of Army Medical University between 2010 and 2016, and the data collected from medical records included admission date, age, gender, premorbid disease, burn etiology, injured anatomical location, burn area and depth, inhalation injury, number of surgeries, length of stay (LOS), clinical outcome, and medical cost. Results Of the 693 older burn patients included, 60.75% were male and 56.85% were aged 60-69 years. Burns peaked in December-March and June. Flame was the most common cause of burns, making up 51.95% of all cases, and also dominated in the burn patients aged 60-69 years. Limbs were the most common anatomical sites of burns (69.41%), and the median total body surface area (Te aged 60-69 years, especially males, regarding incidents in the summer and winter, and flame burns. Moreover, tailored intervention strategies based on related risk factors should be under special consideration. © The Author(s) 2020. DNA Repair inhibitor Published by Oxford University Press.

This study aimed to describe the prevalence and predictors of itch and moderate to severe pain in the first 12 months following a burn injury, and determine the association between itch, moderate to severe pain, work-related outcomes, and health-related quality of life following a burn injury. Methods Burn patients aged 18 years and older were recruited from five Australian specialist burn units. Patients completed the 36-item Short Form Health Survey Version 2 (SF-36 V2), the Sickness Impact Profile (SIP) work scale, and a specially developed questionnaire relating to itch at 1, 6, and 12 months post-injury. Moderate to severe pain was defined as a score less than 40 on the bodily pain domain of the SF-36 V2. Multivariate mixed-effects regression models were used to identify patient and burn injury predictors of itch and moderate to severe pain. Results Three hundred and twenty-eight patients were included. The prevalence of itch benefit from targeted review and intervention studies. © The Author(s) 2020.

These scars can be cosmetically unappealing, but associated symptoms of pruritus, pain and restricted range of motion can impair a person's quality of life. Laser and light therapies offer a minimally invasive, low-risk approach to treatment, with a short postoperative recovery period. As laser technology developed, studies have shown decreased scar thickness, neuropathic pain and need for surgical excision, as well as improved scar pigmentation, erythema, pliability, texture, height and pruritus. In this review, we present the evolution of laser therapy for hypertrophic burn scars, how different types of lasers work, indications, perioperative considerations and guidelines for practice management. © The Author(s) 2020.

We hypothesized that ASCs would improve post-burn wound healing after eschar excision and grafting by increasing wound blood flow via induction of angiogenesis-related pathways. Methods To test the hypothesis, we used an ovine burn model. A 5 cm2 full thickness burn wound was induced on each side of the dorsum. After 24 hours, the burned skin was excised and a 2 cm2 patch of autologous donor skin was grafted. The wound sites were randomly allocated to either topical application of 7 million allogeneic ASCs or placebo treatment (phosphate-buffered saline [PBS]). Effects of ASCs culture media was also compared to those of PBS. Wound healing was assessed at one and two weeks following the application of ASCs. DNA Repair inhibitor Allogeneic ASCs were isolated, cultured and characterized from non-injured healthy sheep. The identity of the ASCs was confirmed by flow cytometry analysis, differentiation into multiple lineages and gene expression via real-time polymerase chain reaction. Wound blood flow, epithelialization, graft size and take and the expression of vascular endothelial growth factor (VEGF) were determined via enzyme-linked immunosorbent assay and Western blot. Results Treatment with ASCs accelerated the patch graft growth compared to the control (p less then  0.05). Topical application of ASCs significantly increased wound blood flow (p less then  0.05). Expression of VEGF was significantly higher in the wounds treated with ASCs compared to control (p less then  0.05). Conclusions ASCs accelerated grafted skin growth possibly by increasing the blood flow via angiogenesis induced by a VEGF-dependent pathway. © The Author(s) 2020.

The severity of peripheral nerve injury can be classified as neurapraxia, axonotmesis or neurotmesis, according to Seddon's classification, or five different degrees according to Sunderland's classification. Patients with neurotmesis suffer from a complete transection of peripheral nerve stumps and are often in need of surgical repair of nerve defects. The applications of autologous nerve grafts as the golden standard for peripheral nerve transplantation meet some difficulties, including donor nerve sacrifice and nerve mismatch. Attempts have been made to construct tissue-engineered nerve grafts as supplements or even substitutes for autologous nerve grafts to bridge peripheral nerve defects. The incorporation of stem cells as seed cells into the biomaterial-based scaffolds increases the effectiveness of tissue-engineered nerve grafts and largely boosts the regenerative process. Numerous stem cells, including embryonic stem cells, neural stem cells, bone marrow mesenchymal stem cells, adipose stem cells, skin-derived precursor stem cells and induced pluripotent stem cells, have been used in neural tissue engineering.
