Background: Experimental animal models remain central to burn research and soft-tissue reconstruction/repair, but method heterogeneity compromises reproducibility, comparability, and translation for depth/area endpoints. Objective: We aimed to map burn-induction methods and examine reproducibility, intentional depth modulation, wound-area stability, validation, and operator-dependent variability. Methods: A PRISMA-ScR review, informed by JBI guidance, was conducted without registration but with predefined questions, criteria, and charting domains. PubMed/MEDLINE, Scopus, Web of Science, Embase, and Google Scholar were searched from inception to 30 January 2026. Eligible studies were English peer-reviewed full-text original in vivo animal studies. Two reviewers independently screened records; one charted data, another checked it. Evidence was mapped by modality, exposure-control architecture, validation, and operator-sensitive steps. Results: Studies varied by species, modality, device design, exposure settings, and severity verification. Modalities were contact, scald, steam, and radiant/infrared. Wound area was more reproducible than depth, which depended on temperature, duration, force/pressure, geometry, equilibration, anatomical site, and assessment timing. Histopathology was the main standard, sometimes complemented by morphometry, optical, or perfusion techniques. Operator-sensitive variability involved force, alignment, contact stability, template integrity, exposure geometry, source stability/environmental control. Conclusions: Burn induction is a measurement-system problem; constraining operator-sensitive variables, predefined validation timing, and quantitative variability reporting may improve validity, comparability, and translation.

The bark of Myrica rubra (Lour.) Siebold & Zucc (M. rubra) is a natural remedy widely used in China and other Asian countries to treat tissue and bone injuries, burns, scalds, gastrointestinal ulcers, and diarrhea. Myricanol is an important ingredient in the bark of M. rubra. This review summarizes articles published over the past 26 years on the pharmacological effects and mechanisms of action of myricanol, aiming to advance research and applications of myricanol. Evidence shows that myricanol has multiple bioactive properties, including antioxidant, anticancer, anti-inflammatory, antimicrobial, antidiabetic, and antihyperlipidemic effects. Myricanol improves metabolic abnormalities in mice by activating the AMPK/SIRT1/PGC-1α signaling pathway. It also demonstrates significant anticancer, antioxidant, and anti-inflammatory actions, primarily by regulating Caspase and BCL-2 family proteins, inhibiting iNOS expression, scavenging free radicals, and interacting with Peroxiredoxin 5. Therefore, myricanol shows great potential for the treatment of cancer, metabolic abnormalities, and inflammatory bowel disease. Further research is needed to improve its bioavailability, confirm its pharmacological effects and mechanisms in vivo, and explore its pharmacokinetic properties and safety. Full article

Background and Objectives: Major burn injury causes profound hypermetabolism and altered thermoregulation. While perioperative hypothermia is linked to adverse outcomes, the prognostic significance of preoperative core temperature in major burn patients remains poorly defined. Therefore, we investigated the association between preoperative core temperature and postoperative mortality in patients with major burns. Materials and Methods: This retrospective study included 635 adult patients with major burns who underwent surgery. Preoperative core temperature was measured in the intensive care unit before surgery. The primary outcome was 90-day postoperative mortality. Secondary outcomes were 30-day postoperative complications, including major adverse cardiovascular events (MACE), bloodstream infection, and continuous renal replacement therapy (CRRT) requirement. Cox proportional hazards regression, receiver operating characteristic (ROC) curve, Kaplan–Meier survival, and restricted cubic spline analyses were performed. Results: The 90-day postoperative mortality rate was 35.6%. Mortality increased in a graded manner as preoperative core temperature decreased. In multivariable Cox regression analysis, preoperative core temperature remained independently associated with 90-day mortality. Restricted cubic spline analysis showed an inverse linear association between preoperative core temperature and mortality risk. ROC curve analysis identified 37.0 °C as an exploratory and hypothesis-generating cohort-specific threshold for risk stratification. Regarding secondary outcomes, the core temperature ≤37.0 °C group had higher rates of MACE, bloodstream infections, and CRRT requirement (all p < 0.05). Conclusions: Lower preoperative core temperature was associated with increased 90-day postoperative mortality in adults with major burns undergoing surgery. Preoperative temperature may serve as a clinically relevant marker of physiologic vulnerability and postoperative risk. Full article

Background/Objectives: Reconstruction of complex soft-tissue defects of the arm and elbow remains challenging because of exposed neurovascular structures, wide joint mobility, and the need to preserve function. The pedicled latissimus dorsi (LD) flap remains a valuable option, particularly when recipient vessels are compromised or functional restoration is required. Given the heterogeneity of these injuries, treatment must be individualized according to each patient’s defect characteristics, functional demands, and rehabilitation goals, reflecting personalized medicine principles. This study evaluated the indications and outcomes of pedicled LD flap transfer in arm and elbow defects. Methods: All consecutive patients who underwent pedicled LD flap reconstruction for upper extremity soft-tissue defects at our institution (January 2015–January 2025) were retrospectively reviewed. Demographic data, defect etiology, flap type, reconstructive goals, complications, and functional outcomes were analyzed. Results: Twenty-six patients were included (mean age 28.5 ± 7.6 years; 84.6% male). Electrical burns were the predominant etiology (92.3%). A musculocutaneous flap was used in 22 patients (84.6%) and a muscle-only flap in 4 (15.4%); supplementary split-thickness skin grafting was required in 17 (65.4%). Reconstructive goals included elbow flexion restoration (±neurovascular repair and soft-tissue coverage) in 12 patients (46.2%) and humeral stump preservation for prosthetic use in 14 (53.8%). No total flap loss occurred. Complications included partial necrosis in 1 patient (3.8%), donor-site seroma in 3 (11.5%), wound dehiscence in 2 (7.7%), and recipient-site hematoma in 1 (3.8%). No patient required amputation or shoulder disarticulation. Conclusions: The pedicled LD flap is a reliable option for complex arm and elbow defects. By tailoring flap design, nerve management, and rehabilitation to individual patient needs, this approach exemplifies personalized reconstructive planning in upper extremity trauma. Full article

Background: Burn injuries are a major cause of morbidity and mortality in low- and middle-income countries, yet remain underreported due to limited data systems. This study describes the epidemiology of burn patients admitted to two major burn centers in Addis Ababa, Ethiopia, and identifies predictors of in-hospital mortality. Methods: A cross-sectional study was conducted among patients with new burn injuries admitted between 1 September 2021, and 1 November 2023, at the Addis Ababa Burn, Emergency, and Trauma Center (AaBET) and Yekatit 12 Medical College (Y12MC) hospitals. Data were extracted from medical records. Descriptive statistics summarized patient characteristics, and binary logistic regression with multivariable analysis identified factors associated with in-hospital mortality using adjusted odds ratios (AORs) and 95% confidence intervals (CIs). Results: Chart completeness was 96.2%. Among 800 patients, 57% were female, with a median age of 18 years (range: 0–89); approximately 80% were under 30 years. Scalds were the leading cause (49.1%). In-hospital mortality was 8.5% (95% CI: 6.5–10.4). Significant predictors included inhalation injury (AOR 6.53), TBSA ≥ 15% (AOR 3.33), deep burns (AOR 1.96), and ICU admission (AOR 14.42). Conclusions: In-hospital mortality was moderate, disproportionately affecting children and young adults, underscoring the need to strengthen critical care and management of severe burns.

Background: Over the past ten years, enzymatic debridement has been used more often to treat burn injuries in the UK and Europe. Even though it is increasingly adopted, there are still major differences in how it is practiced. These differences are mainly due to varying levels of professional experience, differences in the interpretation of available evidence, and concerns about safety and effectiveness. Methods: To help resolve these issues and create more consistent care, the UK National Consensus Working Group was formed. This group brought together burn care experts from different backgrounds to review current methods, published research, and consensus guidelines. They used a structured approach that included educational webinars, a thorough review of the literature, and a national survey using the Delphi method to gather expert opinions and real-world experiences. Results: As a result of this process, the UK Consensus Statement for the Use of Enzymatic Debridement in Burn Care was created and officially approved after extensive consultation at national meetings. The main recommendations focus on safely and effectively including enzymatic debridement in burn care, the need for clear procedures, and identifying areas where further research is needed, such as patient outcomes and dressing methods. Conclusions: The goal of this consensus statement is to unify practices, guide future research, and support ongoing improvements in burn care throughout the UK. Full article

Background: Burn injuries profoundly impact the survivors’ physical, psychological and social well-being, with sexuality, intimacy and body image remaining among the most disrupted yet least addressed areas of rehabilitation. Limited professional training, social discomfort, and a lack of clinical guidance contribute to these unmet needs. Recognizing sexuality as an essential part of health, this interdisciplinary project developed evidence-informed recommendations and communication tools to support both burn survivors and healthcare professionals in discussing intimacy, sexuality, and body image after burn injury. Methods: An interdisciplinary expert group conducted a narrative literature review, supplemented with grey literature and lived experience resources. These insights informed two practical tools: a poster for healthcare professionals and burn centers, and a patient-focused brochure. Both underwent iterative refinement through multicultural feedback from patients and professionals across Europe, Asia and Africa, followed by final validation during an interdisciplinary workshop at the 2025 European Burns Association (EBA) Conference. Results: The literature indicated that burn injuries affect sexuality and body image through interacting physiological, psychological, sensory, relational, and sociocultural factors. Common challenges included reduced desire, anxiety, fear of rejection, altered self-perception, and discomfort initiating conversations about intimacy. Professionals reported limited training, insufficient privacy and cultural barriers. Conclusions: The developed tools and these recommendations aim to normalize dialog, support proactive screening, and promote culturally sensitive patient-centered burn rehabilitation. Embedding sexuality and intimacy within burn care requires ongoing professional training and the identification of dedicated resource persons within each team. Full article

Background: Complex elbow soft-tissue defects often combine exposed critical structures, unstable scars, and high mechanical stress, making durable coverage and early mobilization challenging. Among regional options, the reverse lateral arm flap provides thin fasciocutaneous tissue based on a reliable collateral circulation and preserves major forearm vessels. The aim of this study was to report our single-center experience with the pedicled reverse lateral arm flap for elbow soft-tissue reconstruction, focusing on stable coverage, donor-site morbidity, and functional recovery. Methods: A retrospective single-center case series was conducted at the Division of Plastic Surgery, University Hospital of Padua, Italy. All consecutive patients treated between 2013 and 2023 with a pedicled reverse lateral arm flap for elbow soft-tissue defects were included. Recorded variables included defect etiology, donor-site management, complications, range of motion, and follow-up. Elbow flexion–extension was recorded clinically preoperatively and at last follow-up. Minimum follow-up was 12 months in all patients. Results: Seven patients underwent reconstruction. Defect etiology was burn-related in four cases, shotgun trauma in one, crush injury in one, and melanoma resection in one. All defects were covered with a pedicled reverse lateral arm flap. All flaps survived completely without partial necrosis or flap-related reoperation. Donor-site closure was primary in four patients and required split-thickness skin grafting in three. One patient developed donor-site keloid, and one had donor-site skin-graft partial loss with delayed healing. Elbow flexion–extension improved in all seven cases, with a median gain in arc of motion of 25° (range 15–41°). Conclusions: In this series, the reverse lateral arm flap provided complete coverage of selected elbow defects with preserved motion and limited donor-site morbidity at a minimum follow-up of 12 months. Our findings suggest that it may represent a useful regional option in selected posterior and lateral elbow defects, particularly in post-burn and traumatic settings where thin vascularized tissue is needed, and free-flap reconstruction may be avoidable.

Severe skin injury in humans typically heals through fibrotic remodelling rather than true regeneration, resulting in permanent loss of appendages, sensory function, and tissue architecture. Over the past decades, advances in bulk, single-cell, and spatial transcriptomic profiling have revealed that cutaneous wound repair is governed by dynamic, context-dependent gene-regulatory programmes across epidermal, dermal, vascular, and immune compartments. These studies highlight substantial heterogeneity in keratinocyte, fibroblast, and immune cell states, and identify RNA-mediated regulatory networks that bias healing toward either regenerative or fibrotic outcomes. In parallel, stem cell-derived skin organoids and advanced engineered skin equivalents have emerged as experimental platforms capable of reproducing key aspects of human skin organisation, offering new opportunities to move beyond purely reparative grafting strategies. This review integrates evidence from human or murine skin and wound transcriptomics, RNA-based regulatory mechanisms, and organoid-based skin engineering relevant to trauma and burn reconstruction. We summarise how protein-coding and non-coding RNAs (including miRNAs and lncRNAs) coordinate epithelial migration, inflammation resolution, angiogenesis, and ECM remodelling, and how the dysregulation of these networks contributes to pathological scarring. This article synthesises transcriptomic, RNA regulatory, and skin organoid research to propose a conceptual, hypothesis-generating framework for regenerative skin repair, without claiming clinical readiness or validated therapeutic translation.

Objectives: Seawater-immersed burn wounds are highly susceptible to contamination, persistent inflammation, oxidative stress, and delayed healing, while current irrigation solutions remain suboptimal for such acute injuries. This study aimed to evaluate the therapeutic efficacy and underlying mechanisms of plasma-activated water (PAW) as a novel irrigation strategy for these complex wounds. Methods: The antibacterial efficacy of PAW against marine pathogens was first evaluated in vitro. Subsequently, a rat model of seawater-immersed burn injury was established in male Sprague-Dawley (SD) rats to assess the therapeutic effects of PAW irrigation on wound healing, infection control, and underlying biological mechanisms. Results: In vitro, PAW significantly eradicated two major marine pathogens, Vibrio vulnificus and Vibrio parahaemolyticus (p < 0.001). In vivo, PAW markedly accelerated wound closure, achieving complete healing in 23.60 ± 6.50 days vs. 38.67 ± 2.08 days (Normal saline group) and 58.33 ± 10.97 days (Model group) (p < 0.05). PAW significantly reduced bacterial burden, modulated inflammation by decreasing interleukin-6 and increasing interleukin-10, and alleviated oxidative stress, as evidenced by reduced malondialdehyde levels and enhanced superoxide dismutase activity. Histological evaluation demonstrated enhanced re-epithelialization, collagen deposition, and increased expression of vascular endothelial growth factor and platelet endothelial cell adhesion molecule-1. No adverse effects on serum biochemistry or major organ histopathology were observed. Conclusions: PAW may be a safe, promising, and multifunctional irrigation strategy that promotes seawater-immersed burn healing through coordinated antibacterial, anti-inflammatory, antioxidant, and pro-angiogenic effects, highlighting its strong potential for clinical translation.

Background/Objectives: Reconstruction of complex lower extremity soft tissue defects remains challenging, particularly in the proximal and middle tibial regions, including the knee, where suitable recipient vessels are often limited due to prior trauma, infection, or surgical intervention. This study aimed to evaluate the feasibility and clinical applicability of anterior tibial vessel turnover as an alternative recipient vessel strategy in free flap reconstruction. Methods: A retrospective review was conducted of seven patients who underwent free flap reconstruction using anterior tibial vessel turnover as the recipient vessel between 2019 and 2024. Preoperative imaging was performed to assess vascular status and collateral circulation. Clinical data, including patient demographics, defect characteristics, flap parameters, and postoperative outcomes, were analyzed. Results: The mean patient age was 62.7 years (range, 38–86 years). Defects were primarily located in the proximal and middle tibial regions and were associated with trauma, postoperative infection, chronic osteomyelitis, or burn injury. The mean flap size was 137.4 cm² (range, 49.5–280 cm²). All flaps survived, resulting in a flap survival rate of 100%, with no cases of total flap loss or re-exploration due to vascular compromise. One patient experienced partial flap loss, while no other flap-related complications were observed. Most patients achieved stable wound coverage and favorable functional recovery. Conclusions: Anterior tibial vessel turnover may serve as an alternative recipient vessel strategy for selected cases of complex lower extremity free flap reconstruction. This technique enables microvascular anastomosis in a more superficial and accessible field and expands reconstructive options in cases with compromised recipient vessels. Full article

Background: Hand burns are a key criterion for immediate referral to tertiary burn centres in Australia, New Zealand, and internationally, yet few studies have examined how paediatric burn epidemiology, surgical management, and length of stay (LOS) differ according to the extent of hand involvement. The objective of this study was to describe and compare the demographic profiles, burn injury characteristics, and clinical management between three groups: children with (1) burns involving only the hands, (2) burns involving the hands and other sites, and (3) burns not involving the hands who were admitted to the paediatric Burns Service of Western Australia (BSWA) over a 10-year period. Methods: This cross-sectional study included all burn admissions to the state paediatric burn unit between July 2012 and June 2022. Descriptive statistics and univariate regression used to compare groups. A multivariate log-linear regression model was used to assess the independent association between hand involvement and length of hospital stay, adjusting for identified confounders. T Results: Children with burns isolated to the hands were younger, had a smaller percentage of total body surface area (%TBSA), were more likely to have sustained contact or friction burns, and were more likely to undergo skin grafting procedures compared to those with burns involving the hands and other sites, and those with burns not involving the hands. Despite these differences, hand involvement was not identified as an independent predictor of initial LOS. Conclusion: Paediatric patients with hand burns did not have longer initial hospital admissions than those without hand involvement. Future research needs to assess longer term impacts of hand burns.

Background and Objectives: Extensive burns are devastating injuries, especially in children, associating high risk of morbidity and mortality in the absence of immediate and appropriate treatment. Negative-pressure wound therapy (NPWT) has emerged as a versatile tool for the local treatment of burn wounds. This study aims to present our approach in using NPWT for extensive burns in children, emphasizing the indications and outcomes of these very challenging cases, and proposing an algorithm for NPWT use for extensive burn patients, even in low-resource settings. Materials and Methods: We retrospectively analyzed pediatric burn patients admitted between January 2020 and December 2024, selecting the cases with at least 20% TBSA burn and the application of NPWT during treatment, recording indications and parameters of use, treatment period, and results. Results: We identified 12 patients with a burn surface ranging from 20% to 80% TBSA, caused by high-voltage electrical current (6 cases), flame (4 cases), and scalds (2 cases). NWPT was used for 3–25% TBSA for obtaining granulation tissue in very deep burn wounds with bone and tendon exposure, for reducing edema and enhancing spontaneous re-epithelialization in intermediate circumferential burns, and for preparing the wound bed for re-grafting after local infection and graft failure. There were no complications related with the NPWT use and no fatalities. Conclusions: NPWT represents a reliable option for several clinical situations in local burn treatment, for temporary closure of burn areas, graft fixation, burn wound preparation, local infection control, or enhancing re-epithelialization. The proposed algorithm offers a comprehensive overview of indications of NPWT for burn local management and may guide clinical decisions, easing the identification of the best situation and moment to use the device. Our study contributes to the body of knowledge that enforces the evidence of the safe and effective use of NPWT for burn management in the pediatric population. Full article

Inhalation injury (II) exacerbates burn mortality via obstructive fibrin casts. We evaluated a protocol combining scheduled flexible bronchoscopy (FOB) with nebulized heparin and N-acetylcysteine (NAC). This single-center, randomized controlled trial enrolled 76 mechanically ventilated adult burn patients with bronchoscopically confirmed II. The intervention (n = 38) comprised a 7-day protocol of scheduled FOB with alternating nebulized heparin (5000 IU) and 20% NAC every 4 h. Controls (n = 38) received standard care with on-demand FOB. Primary outcomes were 28-day mortality and day-7 Lung Injury Score (LIS). Unadjusted 28-day mortality was lower in the intervention group (57.9% vs. 81.6%; p = 0.025), alongside a decreased median day-7 LIS (1.0 vs. 1.38; p = 0.021). Respiratory mechanics improved significantly, demonstrating reduced driving pressure and increased static compliance (p < 0.001). However, in multivariable Cox regression, baseline injury severity independently predicted mortality, while the intervention indicated a non-significant hazard reduction trend (aHR = 0.66, 95% CI: 0.36–1.23). No systemic anticoagulation occurred. In conclusion, scheduled FOB with nebulized heparin and NAC improves respiratory mechanics and attenuates lung injury in II. Although unadjusted mortality decreased, baseline severity remains the primary mortality driver, suggesting this protocol is a physiologically beneficial adjunct requiring further multicenter validation. Trial registration: Thai Clinical Trials Registry, TCTR20260408001 (retrospectively registered). Full article

Objectives: To evaluate how often pain is assessed and treated in pediatric trauma patients transported by Emergency Medical Services (EMS) to a pediatric emergency department (ED), and to compare current practice with national recommendations of the Polish Ministry of Health for prehospital pediatric pain management. Methods: We conducted a retrospective analysis of EMS and ED documentation for all trauma patients under 18 years of age transported to the Pediatric Teaching Hospital of the University Clinical Center of the Medical University of Warsaw between 1 January and 31 December 2021. A total of 981 patients with injury or suspected injury or burns were included without exclusion criteria. For patients with documented pain scores, we analyzed pain intensity (0–10), the scales used [Visual Analog Scale (VAS), Numerical Rating Scale (NRS), Wong–Baker Faces Pain Rating Scale (FACES)], body region injured, Glasgow Coma Scale (GCS) score, suspected alcohol or psychoactive substance use, and type and route of analgesic administration. We further evaluated non-pharmacological interventions, pain reassessment, and achievement of at least 50% pain reduction, as defined in national guidelines. Statistical analysis included Student’s t-test or ANOVA for quantitative variables and maximum likelihood chi-square tests for qualitative variables (α = 0.05). Results: Pain was assessed in 839/981 (85.5%) patients; 651/839 (77.6%) reported pain, most frequently of moderate intensity. Despite this, only 208/981 (21.2%) patients received analgesics prehospitally. Morphine and paracetamol were the most frequently used drugs, predominantly administered intravenously, while non-opioid monotherapy was commonly used in patients with lower baseline pain scores. Less than half of all patients received any non-pharmacological intervention whatsoever. Pain was reassessed in 734/839 (87.5%) patients, with a mean reassessment time of approximately 10 min; however, in many cases reassessment occurred earlier than the expected onset of analgesic action. Overall, only 29.4% of patients with pain and documented reassessment achieved the recommended ≥50% reduction in pain intensity, and at least 70.2% of the cohort had no documented evidence of treatment fully complying with national recommendations. Conclusions: In this real-world prehospital and ED cohort, pediatric trauma pain remains under-treated, and adherence to national guidelines on opioid-based analgesia and pain reassessment is suboptimal. Further efforts are needed to improve documentation, expand the recommended pharmacological options for mild pain, and strengthen education on guideline-concordant pediatric pain management in EMS.
