Khamise A, Lapid H, Mishra A, Murray AM. Acute healing outcomes in paediatric partial thickness burns using Epiprotect® and Biobrane®: A retrospective comparative study. J Plast Reconstr Aesthet Surg 2024; 95:55-61. [PMID: 38875874 DOI: 10.1016/j.bjps.2024.05.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2024] [Revised: 04/29/2024] [Accepted: 05/24/2024] [Indexed: 06/16/2024]
Abstract
AIM To compare the acute healing outcomes of Biobrane® and Epiprotect® in paediatric partial thickness (PT) burns. METHODS All paediatric patients (age <18 years) with PT burns managed using either Biobrane® or Epiprotect® over a 5-year period at our burns unit were included. The primary outcome was time to complete healing. Secondary outcomes included adherence, infection rates, length of hospital stay, duration of acute follow-up and return to the theatre. RESULTS Among the 99 patients included, 38 received Epiprotect® and 61 received Biobrane®. The mean total body surface area (TBSA) was 6% (range 1%-15%) and median age was 21 months (range 5-169 months). Median time to healing in the Epiprotect® group was 19.5 days and 16 days in the Biobrane® group (P = .14). The median hospitalisation length was the same for both products (2 days, P = .85). Infection rate was lower in the Epiprotect® group (2.6% vs 16.4%, P = .048). There was no difference in adherence rate. These trends were preserved when depth sub-groups were analysed. Adherence and infection rates were not affected by post-operative antibiotics (P > .99 and P = .65, respectively) in either group. The rate of return to the theatre for further surgery was 13.2% for both products (P > .99). CONCLUSION Our findings demonstrate that acute healing outcomes with Epiprotect® in paediatric PT burns are comparable to those with Biobrane®, with significantly lower infection rates for Epiprotect®. These results suggest that Epiprotect® is a viable alternative to Biobrane®. Nevertheless, further prospective randomised studies are required to investigate the short- and long-term outcomes.

Abstract
Pediatric hand burns are difficult to treat, with thin tissue with critical structures close to the skin and the small scale of the anatomy of children's hands. Additionally, pediatric burns can be challenging due to the concern for donor-site morbidity and the paucity of donor sites when reconstructing these wounds. In this report, we discuss the successful application of a piscine-derived acellular dermal matrix in a 13-month-old child with deep partial thickness and full-thickness burns to the right upper extremity. She had excellent long term cosmetic results and function by 3 years postoperatively, including full extension and flexion of all digits in her right hand.

Abstract
Coverage of burn wounds is crucial to prevent sequalae including dehydration, wound infection, sepsis, shock, scarring, and contracture. To this end, numerous temporary and permanent options for coverage of burn wounds have been described. Temporary options for burn coverage include synthetic dressings, allografts, and xenografts. Permanent burn coverage can be achieved through skin substitutes, cultured epithelial autograft, ReCell, amnion, and autografting. Here, we aim to summarize the available options for burn coverage, as well as important considerations that must be made when choosing the best reconstructive option for a particular patient.

Abstract
BACKGROUND Burns traditionally require frequent, painful dressing changes to minimize infection risk and promote wound healing. To improve care for our pediatric population, our institution adapted a skin graft donor site dressing into a "stick-down" burn dressing consisting of a one-time application of bacitracin and 3% bismuth tribromophenate/vaseline impregnated gauze (Xeroform) that adheres to the burn and peels off as new epithelialized skin forms. The goal of which is to minimize dressing change frequency and patient discomfort in a cost-effective, widely available manner. This study aimed to compare clinical outcomes of the stick-down versus traditional topical dressings. METHODS A retrospective cohort study of pediatric patients (age <18 year) with partial-thickness burns treated at a level I pediatric trauma center for 4 years was conducted. One hundred eleven patients were included: 74 patients treated with daily silver sulfadiazene (Silvadene) dressings matched to 37 patients treated with the Xeroform stick-down dressing using 2:1 propensity score matching. Univariate analyses used Wilcoxon rank sum and Fisher exact tests. RESULTS The cohorts had similar demographics and burn characteristics. Both groups had similar hospitalization rates (31.1% Silvadene, 32.4% Xeroform), most commonly for pain control (54.5% Silvadene, 58.3% Xeroform), with similar average daily narcotic usage (7.7 ± 12.1 morphine milliequivalents Silvadene, 5.1 ± 9.5 Xeroform; P = 0.91). The Xeroform cohort had a shorter but statistically similar hospital stay (median, 1 vs 2 days). In addition, the Xeroform cohort required significantly less dressing changes with a median of 0.5 changes compared with 12 for the Silvadene cohort ( P < 0.0001). There was no difference in time to burn reepithelialization (median, 13.0 days for Silvadene and 12.0 days for Xeroform; P = 0.20) or wound healing complications (12.5% Silvadene, 2.7% Xeroform; P = 0.15). CONCLUSIONS The Xeroform stick-down dressing has equivalent clinical outcomes to that of standard Silvadene dressings for the treatment of pediatric partial-thickness burns with the major advantages of decreasing dressing change frequency, minimizing patient distress and pain, and streamlining clinical care.

Abstract
Second-degree burns are the most common type of burn in clinical practice and hard to manage. Their treatment requires not only a consideration of the different outcomes that may arise from the dressing changes or surgical therapies themselves but also an evaluation of factors such as the burn site, patient age and burn area. Meanwhile, special attention should be given to the fact that there is no unified standard or specification for the diagnosis, classification, surgical procedure, and infection diagnosis and grading of second-degree burn wounds. This not only poses great challenges to the formulation of clinical treatment plans but also significantly affects the consistency of clinical studies. Moreover, currently, there are relatively few guidelines or expert consensus for the management of second-degree burn wounds, and no comprehensive and systematic guidelines or specifications for the treatment of second-degree burns have been formed. Therefore, we developed the Consensus on the Treatment of Second-Degree Burn Wounds (2024 edition), based on evidence-based medicine and expert opinion. This consensus provides specific recommendations on prehospital first aid, nonsurgical treatment, surgical treatment and infection treatment for second-degree burns. The current consensus generated a total of 58 recommendations, aiming to form a standardized clinical treatment plan.

Abstract
The goal of burn wound treatment is to ensure rapid epithelialization in superficial burns and the process of rebuilding the lost skin in deep burns. Topical treatment plays an important role. One of the innovations in the field of synthetic materials dedicated to the treatment of burns is epidermal skin substitutes. Since the introduction of Suprathel®, the alloplastic epidermal substitute, many research results have been published in which the authors investigated the properties and use of this substitute in the treatment of wounds of various origins, including burn wounds. Burn wounds cause both physical and psychological discomfort, which is why ensuring comfort during treatment is extremely important. Alloplastic epidermal substitute, due to its biodegradability, plasticity, no need to remove the dressing until healing, and the associated reduction in pain, is an alternative for treating burns, especially in children.

Abstract
Burns are a main cause of accidental injuries among children in China. Because of the unique wound repair capacity and demand for growth in pediatric patients, the management of pediatric deep partial-thickness burn wounds involves a broader range of treatment options and controversy. We assembled experts from relevant fields in China to reach a consensus on the key points of thermal-induced pediatric deep partial-thickness burn-wound management, including definition and diagnosis, surgical treatments, nonsurgical treatment, choice of wound dressings, growth factor applications, infectious wound treatment, scar prevention and treatment. The committee members hope that the Expert Consensus will provide help and guiding recommendations for the treatment of pediatric deep partial-thickness burn wounds.

Abstract
Skin serves as a protective barrier against infection, prevents excessive fluid and electrolyte losses, performs crucial thermoregulation, and provides tactile feedback of surroundings. The skin also plays an essential role in human perception of body image, personal appearance, and self-confidence. With these many diverse functions, understanding normal anatomic composition of skin is pivotal to evaluating the extent of its disruption from burn injury. This article discusses the pathophysiology, initial evaluation, subsequent progression, and healing of burn wounds. By delineating the various microcellular and macrocellular alterations of burn injury, this review also augments providers' capacity to deliver patient-centered, evidence-based burn care.

Abstract
Deep partial and full-thickness burns require surgical treatment with autologous skin grafts after necrectomy, which is the generally accepted way to achieve permanent wound coverage. This study sought to examine the grafted and donor areas of children who underwent autologous skin transplantation, using two assessment scales to determine the severity of the scarring and the cosmetic outcome during long-term follow-up. At the Surgical Unit of the Department of Paediatrics of the University of Pécs, between 1 January 2015 and 31 December 2019, children who had been admitted consecutively and received autologous skin transplantation were analyzed. Twenty patients met the inclusion criteria in this retrospective cohort study. The authors assessed the results using the Patient and Observer Scar Assessment Scale (POSAS) and the Vancouver Scar Scale (VSS). There was a significant difference in how parents and examiners perceived the children’s scars. In the evaluation of the observer scale, the most critical variables for the area of skin grafted were relief and thickness. Besides color, relief was the worst clinical characteristic on the patient scale. However, when medical professionals evaluated the donor site, significantly better results were obtained compared to the transplanted area (average observer scale score: 1.4 and 2.35, p = 0.001; VSS: 0.85 vs. 2.60, p < 0.001), yet it was similar to the graft site in the parents’ opinion (Patient Scale: 2.95 and 4.45, p = 0.181).

Abstract
Background and Objectives: Scar formation after burn trauma has a significant impact on the quality of life of burn patients. Hypertrophic scars or keloids can be very distressing to patients due to potential pain, functional limitations, or hyper- or hypopigmentation. In a previous study comparing Suprathel® and the new and cheaper dressing epicitehydro®, we were able to show that pain reduction, exudation, and time until wound-healing of partial-thickness burn wounds were similar, without any documented infections. No study exists that objectively measures and compares skin and scar quality after treatment with Suprathel® and epicitehydro® at present. Materials and Methods: In this study, the scar quality of 20 patients who had been treated with Suprathel® and epicitehydro® was objectively assessed using the Cutometer®, Mexameter®, and Tewameter®, as well as subjectively with the Patient and Observer Scar Assessment Scale, 3, 6, and 12 months after burn injury. Results: In all performed measurements, no significant differences were detected in scar formation after treatment of partial-thickness burn wounds with the two dressings. Conclusions: Both the newer and less expensive wound-dressing epicitehydro® and the well-known wound-dressing Suprathel® resulted in stable wound closure and showed good cosmetic results in the follow-up examinations.

Abstract
Introduction Paediatric burns are a common clinical presentation. The long-term scar outcomes in paediatric burns patients are relatively unknown as most are discharged after 6 weeks follow up, apart from the small number that are followed up by scar services depending on geographical availability. We aimed to determine whether the long-term scarring outcomes are significantly different in those who had surgical treatment with Versajet® debridement and Biobrane®, vs. those treated conservatively with non-adherent Mepitel® and Acticoat® dressings, in a cohort of paediatric burns patients. Methods The parents of all paediatric burns patients admitted to Stoke Mandeville Hospital from October 2014 to September 2017 were contacted by telephone to fill in the paediatric Brisbane Burn Scar Impact Profile (BBSIP), the only patient reported outcome measure (PROM) specifically aimed at children. The results from the questionnaires underwent statistical analysis to see if there was a significant difference in questionnaire scores between children treated surgically vs. those treated conservatively. Results A total of 107 children were admitted in the timeframe, responses were received from 34 patients with 13 having been treated surgically and 21 having been treated conservatively. In all 58 questions that make up the BBSIP, there was no statistically significant difference observed in the scores of those treated surgically vs. those treated conservatively. For 31 questions on the BBSIP, the lowest score indicating the best outcome was observed in all patients in both groups. Discussion Surgical management for burns is always the last resort. Our results could be interpreted to suggest clinicians need not fear the longer-term impact a scar may have when deciding whether to treat a paediatric burns patient surgically or conservatively. This study is the first to assess longer-term scar outcomes using the BBSIP. A larger data set and comparison with other burn units in the UK may help to provide more information on scar outcomes between different methods of surgical and conservative treatment. We found no statistically significant difference in the long-term scar outcomes as assessed by the BBSIP in paediatric burn patients treated with Versajet® debridement and Biobrane®, vs. those treated conservatively with non-adherent Mepitel® and Acticoat® dressings.

Abstract
Significance: The worldwide estimate of burns requiring medical attention each year is 11 million. Each year in the United States, ∼486,000 burn injuries receive medical attention, including 40,000 hospitalizations. Scars resulting from burns can be disfiguring and impair functions. The development of prophylactic drugs for cutaneous scarring could improve the outcomes for burns, traumatic lacerations (>6 million/year treated in U.S. emergency rooms), and surgical incisions (∼250 million/year worldwide). Antiscar pharmaceuticals have been estimated to have a market of $12 billion. Recent Advances: Many small molecules, cells, proteins/polypeptides, and nucleic acids have mitigated scarring in animal studies and clinical trials, but none have received Food and Drug Administration (FDA) approval yet. Critical Issues: The development of antiscar pharmaceuticals involves the identification of the proper dose, frequency of application, and window of administration postwounding for the indicated wound. Risks of infection and impaired healing must be considered. Scar outcome needs to be evaluated after scars have matured. Future Directions: Once treatments have demonstrated safety and efficacy in rodent and/or rabbit and porcine wound models, human testing can begin, such as on artificially created wounds on healthy subjects and on bilateral-surgical wounds, comparing treatments versus vehicle controls on intrapatient-matched wounds, before testing on separate cohorts of patients. Given the progress made in the past 20 years, FDA-approved drugs for improving scar outcomes may be expected.

BACKGROUND The Choosing Wisely Campaign was launched in 2012 and has been applied to a broad spectrum of disciplines in almost thirty countries, with the objective of reducing unnecessary or potentially harmful investigations and procedures, thus limiting costs and improving outcomes. In Canada, patients with burn injuries are usually initially assessed by primary care and emergency providers, while plastic or general surgeons provide ongoing management. We sought to develop a series of Choosing Wisely statements for burn care to guide these practitioners and inform suitable, cost-effective investigations and treatment choices. METHODS The Choosing Wisely Canada list for Burns was developed by members of the Canadian Special Interest Group of the American Burn Association. Eleven recommendations were generated from an initial list of 29 statements using a modified Delphi process and SurveyMonkey™. RESULTS Recommendations included statements on avoidance of prophylactic antibiotics, restriction of blood products, use of adjunctive analgesic medications, monitoring and titration of opioid analgesics, and minimizing 'routine' bloodwork, microbiology or radiological investigations. CONCLUSIONS The Choosing Wisely recommendations aim to encourage greater discussion between those involved in burn care, other health care professionals, and their patients, with a view to reduce the cost and adverse effects associated with unnecessary therapeutic and diagnostic procedures, while still maintaining high standards of evidence-based burn care.

Platelet distribution width associated with short-term prognosis and cost in paediatrics with partial-thickness thermal burns: A retrospective comparative study. Int Wound J 2022; 19:1853-1859. [PMID: 35706362 DOI: 10.1111/iwj.13791] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 02/24/2022] [Accepted: 03/05/2022] [Indexed: 12/01/2022] Open
Abstract
Platelets exert important roles in burn wound healing and involving in inflammatory regulation and tissue repair. Platelet distribution width (PDW) is an indicator representing platelet morphology and activation. In this study, we try to evaluate the value of PDW in predicting short-term prognosis and cost of paediatrics with partial-thickness thermal burns. This retrospective study enrolled 73 children with partial-thickness thermal burns. The Ability of PDW to predict wound healing was evaluated by receiver operating characteristic (ROC) curve. All 73 patients were assigned into high and low PDW group according to optimal cut-off value from ROC curve. Associations between PDW and 2-weeks healing rate, time to wound healing, in-hospital cost and length of stay were evaluated. Furthermore, Univariate and multivariate logistic regression analysis were used to furtherly evaluate the significance of PDW in wound healing. We found that all baseline characteristics between groups were comparable (all P > .05). High PDW group had a significant higher 2-weeks wound healing rate than those with a low PDW (66.7% versus 32.6%, P < .01). Moreover, the mean time to wound healing of high PDW was obviously shorter than that of low PDW group (15.4 ± 10.1 vs 20.7 ± 10.9, P = .04). Univariate (OR: 0.24, 95%CI: 0.09-0.65, P < .01) and multivariate (OR: 0.15, 95CI%:0.05-0.52, P < .01) analysis confirmed PDW as an independent marker for wound healing. Patients in high PDW group had a significant lower medical burden than low PDW group, including in-hospital cost (13.7 ± 10.6 vs 21.9 ± 16.7, ×103RMB, P = .02) and length of stay (12.2 ± 8.8 vs 19.0 ± 10.8 days, P < .01). In conclusion, PDW can sever as a potential indictor to predict the short-term prognosis of paediatrics with partial thickness thermal burns.

Abstract
BACKGROUND Management of pediatric thermal injuries involves a high standard of care in a multidisciplinary setting. To avoid physical and psychological sequelae, wound dressings should minimize hospitalization time and anesthesia while maximizing patient comfort. PATIENTS AND METHODS 190 children with thermal injuries of the torso, arms and legs were treated with polyurethane foam dressings or bacterial nanocellulose sheets. Data were analyzed retrospectively regarding hospitalization, procedures with general anesthesia, scar formation, rate of infection and need for skin grafting. RESULTS The groups did not differ significantly concerning age, gender distribution or percentage of injured total body surface area. Statistical analysis showed that length of hospitalized care and procedures undergoing anesthesia were significantly reduced in the nanocellulose group (each p < 0.0001). There was no significant difference in rate of complications, wound healing and rate of skin grafting between the two subgroups. DISCUSSION Acting as a temporary epidermal substitute, bacterial nanocellulose enables undisturbed reepithelialization without further wound dressing changes. In children, no additional topical antimicrobial agents are indicated for unimpaired wound healing. CONCLUSIONS Bacterial nanocellulose is superior to polyurethane foam regarding length of hospitalization and number of interventions under anesthesia. It offers a safe, cost-effective treatment option and provides excellent comfort in pediatric patients.

Abstract
Background: Paediatric second-degree burn injuries are a significant source of medical challenges to the population that may cause severe, lifelong complications. Currently, there are dozens of therapeutic modalities and we aimed to summarise their reported outcomes and determine their effectiveness, compared to the widely used silver sulphadiazine (SSD). Methods: We conducted the meta-analysis and systematic review of randomised controlled trials (RCTs), which investigated the performance of dressings in acute paediatric partial-thickness burns. The evaluated endpoints were time until wound closure, grafting and infection rate, number of dressing changes and length of hospitalisation. Results: Twenty-nine RCTs were included in the qualitative and 25 in the quantitative synthesis, but only three trials compared SSD directly to the same intervention (Biobrane). Data analysis showed a tendency for faster healing times and a reduced complication rate linked to biosynthetic, silver foam and amnion membrane dressings. A substantial difference was found between the number of dressing changes associated with less pain, narcosis and treatment duration. Conclusions: Considerable between-study heterogeneity was caused by the unequal depth subcategory ratio and surface area of the injuries; therefore, no significant difference was found in the main outcomes. Further research is necessary to establish the most effective treatment for these burns.

Abstract
AbstractBurns disrupt the protective skin barrier with consequent loss of cutaneous temperature regulation, infection prevention, evaporative losses, and other vital functions. Chronically, burns lead to scarring, contractures, pain, and impaired psychosocial well-being. Several skin substitutes are available and replace the skin and partially restore functional outcomes and improve cosmesis. We performed a literature review to update readers on biologic and synthetic skin substitutes to date applied in acute and reconstructive burn surgery. Improvement has been rapid in the development of skin substitutes in the last decade; however, no available skin substitute fulfills criteria as a perfect replacement for damaged skin.

Abstract
Many congenital malformations often require a multidisciplinary and multistep surgical treatment, including the use of biological membranes. Aims of the study were to describe the use of these membranes for the correction of malformations, their clinical performance at follow-up, and patient's tolerance to them. The study included patients treated between 2009 and November 2020 in two referral centers. They were affected by abdominal wall defects (AWD), esophageal atresia/tracheo-esophageal fistula (EA/TEF), diaphragmatic hernia (CDH), spinal defects (SD), and anorectal malformations (ARM). The human origin membranes used during surgery were amniotic membrane, fascia lata, and pericardium provided by the local tissue bank and the porcine-derived membrane available on the market. Thirty-one patients were retrieved. The sample included 10 AWD, 7 EA/TEF, 5 CDH, 4 SD, 2 ARM, and 3 miscellaneous defects. The median age at repair was 139 days (range: 10,5–1494). The median follow-up was 1021 days (range: 485,5–1535). Two patients were lost at follow-up. The defects were successfully repaired and the membranes perfectly tolerated in 28/29 cases. In 1 case of CDH the fascia lata was replaced with a Goretex patch due to recurrence of the defect. This is the largest series on the use of biological membranes in congenital malformations. The variety of tissues allows to choose the best material for each malformation. The excellent tolerance and performance of this first series of patients encourage the use of these membranes to correct different type of malformations at any age.

Comparison of wound healing and patient comfort in partial-thickness burn wounds treated with SUPRATHEL and epicte hydro wound dressings. Int Wound J 2021; 19:782-790.

Abstract
Among the available dressings for partial‐thickness burn wound treatment, SUPRATHEL has shown good usability and effectiveness for wound healing and patient comfort and has been used in many burn centres in the last decade. Recently, bacterial nanocellulose (BNC) has become popular for the treatment of wounds, and many studies have demonstrated its efficacy. epicitehydro, consisting of BNC and 95% water, is a promising product and has recently been introduced in numerous burn centres. To date, no studies including direct comparisons to existing products like SUPRATHEL have been conducted. Therefore, we aimed to compare epicitehydro to SUPRATHEL in the treatment of partial‐thickness burns. Twenty patients with partial‐thickness burns affecting more than 0.5% of their total body surface area (TBSA) were enrolled in this prospective, unicentric, open, comparative, intra‐individual clinical study. After debridement, the wounds were divided into two areas: one was treated with SUPRATHEL and the other with epicitehydro. Wound healing, infection, bleeding, exudation, dressing changes, and pain were documented. The quality of the scar tissue was assessed subjectively using the Patient and Observer Scar Scale. Wound healing in patients with a mean TBSA of 9.2% took 15 to 16 days for both treatments without dressing changes. All wounds showed minimal exudation, and patients reported decreased pain with the only significant difference between the two dressings on day 1. No infection or bleeding occurred in any of the wounds. Regarding scar evaluation, SUPRATHEL and epicitehydro did not differ significantly. Both wound dressings were easy to use, were highly flexible, created a safe healing environment, had similar effects on pain reduction, and showed good cosmetic and functional results without necessary dressing changes. Therefore, epicitehydro can be used as an alternative to SUPRATHEL for the treatment of partial‐thickness burn wounds.

Abstract
INTRODUCTION Systematic reviews (SR) of high-quality randomised controlled trials can identify effective treatments for burn wound infections (BWIs). Clinical heterogeneity in outcome definitions can prevent valid evidence synthesis, which may limit the reliability of the findings of SRs affected by this heterogeneity. This SR aimed to investigate whether there is variation BWI definitions across studies in SRs of burn care interventions and its impact on identification of effective treatments for patients with burn injuries. METHODS A systematic search of five databases was conducted. Included SRs were: in English, published from January 2010 to October 2018, assessed intervention effects for patients with a burn injury, and reported data about BWI. RESULTS Twenty-nine SRs, which included 248 studies reporting BWI outcomes, were included in our final dataset. Three SRs used a definition of BWI to select studies for inclusion. Fourteen reported BWI definitions from included studies in the review results. There was heterogeneity of BWI definition in their included studies; across 29 SRs, 32 different BWI indicators were used, with the median across SRs ranging from 1 to 7 (range 1-14). Fourteen SRs accounted for BWI definition heterogeneity in their conclusions, indicating that the issue impacted whether a conclusion could be drawn, and limited the validity of the SR findings. CONCLUSIONS There is variation in BWI definition across SRs and within the studies included in SRs of interventions assessing BWI outcomes. This heterogeneity has prevented conclusions about intervention effects being drawn, and only half of the SR authors have accounted for it in their findings. Reviews that have collated this data without reference to the heterogeneity should be viewed with caution, since it may limit the validity of evidence for the identification of effective treatments for BWI. The use of a newly developed core indicator set to support consistent reporting of indicators and standardisation of BWI outcome reporting will enable effective evidence synthesis.

Abstract
Treadmill burns that occur from friction mechanism are a common cause of hand burns in children. These burns are deeper and more likely to require surgical intervention compared to hand burns from other mechanisms. The purpose of this study was to identify the factors associated with healing time using an initial nonoperative approach. A retrospective chart review was performed examining children (<15 years) who were treated for treadmill burns to the hand between 2012 and 2019. Patient age, burn depth, total body surface area of the hand injury, and time to healing were recorded. Topical wound management strategies (silver sheet, silver cream, non-silver sheet, and non-silver cream) and associated treatment durations were determined. For patients with burns to bilateral hands, the features, treatment, and outcomes of each hand were assessed separately. Cox regression analysis was used to evaluate the association between time to healing and patient characteristics and treatment type. Seventy-seven patients with 86 hand burns (median age 3 years, range 1-11) had a median total body surface area per hand burn of 0.8% (range 0.1-1.5%). Full-thickness burns (n = 47, 54.7%) were associated with longer time to healing compared to partial-thickness burns (HR 0.28, CI 0.15-0.54, P < .001). Silver sheet treatment was also associated with more rapid time to healing compared to treatment with a silver cream (HR 2.64, CI 1.01-6.89, P = .047). Most pediatric treadmill burns can be managed successfully with a nonoperative approach. More research is needed to confirm the superiority of treatment with silver sheets compared to treatment with silver creams.

Abstract
The COVID-19 pandemic has dramatically impacted healthcare provision in the UK and burns services have had to adapt to ensure the continuity of a safe care. As we return to “normality” we reflect on lessons learnt from our response to this pandemic. A service evaluation was performed from patient notes between March 23rd and May 8th 2020 and an anonymous survey given to patients attending outpatient appointments. 258 patients were referred to our burns service and 148 patients completed the survey. Eleven burns were caused by treatment or prevention of COVID-19. Patients delayed seeking medical attention due to concern of catching COVID-19 (36% adults, 8% children). There was a delay in referral of 17 patients despite them fulfilling the referral criteria. Infection rates were higher following delayed presentation (21% vs 6%). The majority of burns were managed conservatively (237/258). Dressing changes were performed at home by 32% of patients. The outreach team treated 22 patients. During the pandemic telemedicine has improved the efficiency of outpatient burn care and outreach nurses have enabled treatment of vulnerable patients. More must be done to raise public awareness of preventable causes of burn injury and to reassure them to seek help when burns occur.

Abstract
Burns represent the fifth most common cause of nonfatal childhood injuries in the world. The Nile tilapia skin (Oreochromis niloticus) is widely available in Brazil and demonstrated, in previous studies, noninfectious microbiota, morphological structure similar to that of human skin, and good outcomes when used as a xenograft for treatment of experimental burns in rats. A 3-year-old boy was admitted to a burn treatment center in Fortaleza, Brazil, with scalds in the left side of the face, neck, anterior thorax, abdomen, and left arm. Involvement of 18% of total body surface area with superficial partial thickness burns was calculated. After local Institutional Review Board approval and written permission from the patient's legal caregiver were obtained, application of tilapia skin as an occlusive dressing was performed. Good adherence of tilapia skin to the wound bed was detected. The patient was discharged from the hospital with a total of 10 days required for the complete re-epithelialization of his superficial partial thickness burn. No adverse effects were noted. We believe that further studies conducted by our researchers will allow this innovative, low-cost, widely available and easy to apply biomaterial to firm itself as a relevant option in the therapeutic arsenal of pediatric burns, producing significant social and financial impact for the health system.

Abstract
Objective: To assess the safety and efficacy of a surfactant-based technology for the management of burns. Method: In a retrospective review, paediatric patients with different types of burns were treated with the gel technology. In some patients, the treatment was combined with a topical antimicrobial agent. Primary objectives of the review were the assessment of healing, healing times and ease of use of the material. Results: The wounds of 15 paediatric patients with different types of burns, particularly with regard to depth and anatomical location, were evaluated using a retrospective chart review. It was found that the surfactant gel technology, with or without the topical antimicrobial agent, assisted in autolytic debridement, and that time to re-epithelialisation was short and within the range of those obtained with other established treatments. Conclusion: The number of patients and wounds in this evaluation is small but the study indicates that the gel technology provides a safe and effective way to treat smaller burns in paediatric patients.

Abstract
NexoBrid (NXB) has been proven to be an effective selective enzymatic debridement agent in adults. This manuscript presents the combined clinical trial experience with NXB in children. Hundred and ten children aged 0.5 to 18 years suffering from deep thermal burns of up to 67% total body surface area were treated with NXB in three clinical trials. Seventy-seven children were treated with NXB in a phase I/II study, where 92.7% of the areas treated achieved complete eschar removal within 0.9 days from admission. Thirty-three children (17 NXB, 16 standard of care [SOC]) participated in a phase III randomized controlled trial. All wounds treated with NXB achieved complete eschar removal. Time to complete eschar removal (from informed consent) was 0.9 days for NXB vs 6.5 days for SOC (P < .001). The incidence of surgical excision was 7.9% for NXB vs 73.3% for SOC (P < .001). Seventeen of these children participated in a phase III-b follow-up study (9 NXB and 8 SOC). The average long-term modified Vancouver Scar Scale scores were 3.4 for NXB-treated wounds vs 4.4 for SOC-treated wounds (NS). There were no significant treatment-related adverse events. Additional studies are needed to strengthen these results.

Abstract
This study aims to evaluate the efficacy of Nile tilapia skin as a xenograft for the treatment of partial-thickness burn wounds in children. This is an open-label, monocentric, randomized phase II pilot study conducted in Fortaleza, Brazil. The study population consisted of 30 children between the ages of 2 and 12 years with superficial "partial-thickness" burns admitted less than 72 hours from the thermal injury. In the test group, the tilapia skin was applied. In the control group, a thin layer of silver sulfadiazine cream 1% was applied. Tilapia skin showed good adherence to the wound bed, reducing the number of dressing changes required, the amount of anesthetics used, and providing benefits for the patients and also for healthcare professionals, by reducing the overall work load. The number of days to complete burn wound healing, the total amount of analgesics required throughout the treatment, burn improvement on the day of dressing removal, and pain throughout the treatment were similar to the conventional treatment with silver sulfadiazine. Thus, tilapia skin can be considered an effective and low-cost extra resource in the therapeutic arsenal of pediatric superficial partial thickness burns.

Abstract
INTRODUCTION EpiProtect® is a biosynthetic cellulose dressing indicated for the treatment of superficial burns and the dressing of deep burns. Prior to this study the youngest reported patient treated with EpiProtect® was aged 13 years. METHOD Data were collected prospectively for patients aged < 5 years, presenting to the Children's Burns Unit with ⩾ 2% total body surface area (TBSA) burns sustained by any mechanism. RESULTS Thirty children were treated (median age = 17 months, age range = 1-61 months). Thirty-six burn depths were documented: superficial partial thickness (SPT) in 53% (n=19); mid-partial thickness (MPT) in 33% (n=12); deep partial thickness (DPT) in 11% (n=4); and full thickness (FT) in 3% (n=1). Median burn size was 4.5% TBSA (range = 2%-12%). EpiProtect® was applied under general anaesthesia in all cases. The median length of stay (LOS) was two days (range = 0-6 days). EpiProtect® was tolerated well and provided effective analgesia for subsequent dressing changes. Median healing time was 13 days (SPT burns), 14 days (MPT) and 24 days (DPT burns). Three patients required split skin grafting. Hypertrophic scarring arose in one patient. DISCUSSION This case series represents the youngest published patient group to have been treated with EpiProtect®. Authors conclude that EpiProtect® provides a safe, reliable and well-tolerated dressing option for all burn depths in young children. Importantly, EpiProtect® is culturally neutral and may be used in situations which, for cultural reasons, may preclude the use of animal-derived products. Further studies are warranted to evaluate pain scores, burn depth, size and LOS correlation, and comparative analysis between dressing types. LAY SUMMARY Burn injuries in the paediatric population are common and often require multiple dressing changes. Dressing changes can be painful and distressing to both children and their care givers. This article describes the experience of using a synthetically derived burns dressing, called EpiProtect®, in children aged ⩽ 5 years. Thirty patients were recruited with varying depths of scald burns and all underwent application of EpiProtect® dressing. The results suggested that EpiProtect® was a user-friendly dressing that can be used to treat partial-thickness burns and to dress full-thickness (FT) burns. It was well-tolerated and provided effective analgesia at the time of dressing changes. There was no incidence of increased burn wound infection rates and all wounds healed. In addition, as EpiProtect® is a synthetic product, it has the benefit of being culturally neutral, which is advantageous in a culturally diverse population. Further studies are warranted to evaluate the effectiveness of this dressing and to compare it to similar dressings that are available.

Abstract
Conventional wound dressings are difficult to apply to large total body surface area (TBSA) wounds, as they typically are prefabricated, require a layer of adhesive coating for fixation, and need frequent replacement for entrapped exudate. Large TBSA wounds as well as orthopedic trauma and low-resource surgery also have a high risk of infection. In this report, a sprayable and intrinsically adhesive wound dressing loaded with antimicrobial silver is investigated that provides personalized fabrication with minimal patient contact. The dressing is composed of adhesive and biodegradable poly(lactic-co-glycolic acid) and poly(ethylene glycol) (PLGA/PEG) blend fibers with or without silver salt (AgNO3). in vitro studies demonstrate that the PLGA/PEG/Ag dressing has antimicrobial properties and low cytotoxicity, with antimicrobial silver controllably released over 7-14 days. In a porcine partial-thickness wound model, the wounds treated with both antimicrobial and nonantimicrobial PLGA/PEG dressings heal at rates similar to those of the clinical, thin film polyurethane wound dressing, with similar scarring. However, PLGA/PEG adds a number of features beneficial for wound healing: greater exudate absorption, integration into the wound, a 25% reduction in dressing changes, and tissue regeneration with greater vascularization. There is also modest improvement in epidermis thickness compared to the control wound dressing.

Abstract
INTRODUCTION The modified Meek micrografting technique has been used in the treatment of severely burned patients and a number of articles have examined the use of the modified Meek technique in adults and in mixed-age groups. However, there is a paucity of research pertaining to the outcome in the pediatric age group. The aim of this study is to present our favorable outcome in pediatric major burns using the modified Meek technique. METHODS A retrospective review of burn cases in Hospital Universiti Sains Malaysia from 2010 to 2015 was conducted. Cases of major burns among pediatric patients grafted using the Meek technique were examined. RESULTS Twelve patients were grafted using the Meek technique. Ten (91.7%) patients were male, whereas 2 (8.3%) were female. The average age of patients was 6 years (range, 2-11 years). The average total body surface area was 35.4% (range, 15%-75%). Most burn mechanisms were due to flame injury (66.7%) as compared with scalds injury (16.7%) and chemical injury (16.7%). There was no mortality. All patients were completely grafted with a good donor site scar. The average graft take rate was 82.3%, although 8 cases had positive tissue cultures from the Meek-grafted areas. The average follow-up duration was 3.6 years (range, 1.1-6.7 years). Only 1 case developed contracture over minor joint. CONCLUSIONS The Meek technique is useful when there is a paucity of donor site in the pediatric group. The graft take is good, contracture formation is low, and this technique is cost-effective.

Abstract
The promise of regenerative medicine and tissue engineering is founded on the ability to regenerate diseased or damaged tissues and organs into functional tissues and organs or the creation of new tissues and organs altogether. In theory, damaged and diseased tissues and organs can be regenerated or created using different configurations and combinations of extracellular matrix (ECM), cells, and inductive biomolecules. Regenerative medicine and tissue engineering can allow the improvement of patients' quality of life through availing novel treatment options. The coupling of regenerative medicine and tissue engineering with 3D printing, big data, and computational algorithms is revolutionizing the treatment of patients in a huge way. 3D bioprinting allows the proper placement of cells and ECMs, allowing the recapitulation of native microenvironments of tissues and organs. 3D bioprinting utilizes different bioinks made up of different formulations of ECM/biomaterials, biomolecules, and even cells. The choice of the bioink used during 3D bioprinting is very important as properties such as printability, compatibility, and physical strength influence the final construct printed. The extracellular matrix (ECM) provides both physical and mechanical microenvironment needed by cells to survive and proliferate. Decellularized ECM bioink contains biochemical cues from the original native ECM and also the right proportions of ECM proteins. Different techniques and characterization methods are used to derive bioinks from several tissues and organs and to evaluate their quality. This review discusses the uses of decellularized ECM bioinks and argues that they represent the most biomimetic bioinks available. In addition, we briefly discuss some polymer-based bioinks utilized in 3D bioprinting.

Abstract
Due to its strong antimicrobial activity, silver is a commonly used adjunct in wound care. However, it also has the potential to impair healing by exerting toxic effects on keratinocytes and fibroblasts. The published literature on the use of silver in wound care is very heterogeneous, making it difficult to generate useful treatment guidelines. METHODS A search of high-quality studies on the use of silver in wound care was performed on PubMed. A detailed qualitative analysis of published articles was performed to evaluate the evidence for the use of silver in infected wounds, clean wounds, burns, and over closed surgical incisions. RESULTS Fifty-nine studies were included in this qualitative analysis. We found that, overall, the quality of the published research on silver is poor. While there is some evidence for short-term use of dressings containing nanocrystalline silver in infected wounds, the use of silver-containing dressings in clean wounds and over closed surgical incisions is not indicated. Negative-pressure wound therapy accelerates the healing of contaminated wounds, especially when silver is used as an adjunct. For burns, silver sulfadiazine slows healing and should not be used. Instead, nanocrystalline silver, or alternatives such as octenidine and polyhexanide, lead to less infection and faster healing. CONCLUSIONS In infected wounds, silver is beneficial for the first few days/weeks, after which nonsilver dressings should be used instead. For clean wounds and closed surgical incisions, silver confers no benefit. The ideal silver formulations are nanocrystalline silver and silver-coated polyurethane sponge for negative-pressure wound therapy. Silver sulfadiazine impairs wound healing. Proper use of silver-containing dressings is essential to optimize wound healing.

Abstract
INTRODUCTION Antibiotic or silver-based dressings are widely used in burn wound care. Our standard method of dressing pediatric extremity burn wounds consists of an antibiotic ointment or nystatin ointment-impregnated nonadherent gauze (primary layer), followed by rolled gauze, soft cast pad, plaster and soft casting tape (3M™ Scotchcast™, St. Paul, MN). The aim of this study was to compare our standard ointment-based primary layer versus Mepitel Ag® (Mölnlycke Health Care, Gothenburg, Sweden) in the management of pediatric upper and lower extremity burn wounds. METHODS Children with a new burn injury to the upper or lower extremities, who presented to the burn clinic were eligible. Eligible children were enrolled and randomized, stratified by burn thickness, to be dressed in an ointment-based dressing or Mepitel Ag®. Study personnel and participants were not blinded to the dressing assignment after randomization. Dressings were changed approximately once or twice per week, until the burn wound was healed or skin-grafted. The primary outcome was time to wound healing and p-value < 0.05 was considered significant. RESULTS Ninety-six children with 113 upper or lower extremity burns were included in the analysis. Mepitel Ag® (hazard ratio [HR] 0.57 (95% Confidence Interval (CI) 0.40-0.82); p = 0.002) significantly reduced the rate of wound healing, adjusting for burn thickness and fungal wound infection. The incidence of fungal wound infections and skin grafting was similar between the two groups. Children randomized to standard ointment dressings were significantly less likely to require four or more burn clinic visits than those in the Mepitel Ag® (4% versus 27%; p = 0.004). CONCLUSION Our study shows that our standard ointment-based dressing significantly increases the rate of wound healing compared to Mepitel Ag® for pediatric extremity burn injuries. LEVEL OF EVIDENCE Treatment study; Level 1.

Abstract
AIM Our aim was to compare two different regimens for the treatment of children with partial-thickness scalds. These were treated with either a porcine xenograft (EZderm®, Mölnlycke Health Care, Gothenburg, Sweden) or a silver-foam dressing (Mepilex® Ag, Mölnlycke Health Care, Gothenburg, Sweden). METHODS We organised a prospective randomised clinical trial that included 58 children admitted between May 2015 and May 2018 with partial-thickness scalds to The Burn Centre in Linkoping, Sweden. The primary outcome was time to healing. Secondary outcomes were pain, need for operation, wound infection, duration of hospital stay, changes of dressings, and time taken. RESULTS The patients treated with silver-foam dressing had a significantly shorter healing time. The median time to 97% healing for this group was 9 (7-23) days compared to 15 (9-29) days in the porcine xenograft group (p = 0.004). The median time to complete healing for the silver-foam group was 15 (9-29) days and for the porcine xenograft group 20.5 (11-42) days (p = 0.010). Pain, wound infection, duration of hospital stay, and the proportion of operations were similar between the groups. Number of dressing changes and time for dressing changes were lower in the silver-foam dressing group (p = 0.03 for both variables). CONCLUSIONS We compared two different treatments for children with partial-thickness scalds, and the data indicate that wound healing was faster, fewer dressing changes were needed, and dressing times were shorter in the silver-foam group.

Abstract
BACKGROUND To our knowledge this is the first published estimate of the charges of the care of burns in Sweden. The Linköping Burn Interventional Score has been used to calculate the charges for each burned patient since 1993. The treatment of burns is versatile, and depends on the depth and extension of the burn. This requires a flexible system to detect the actual differences in the care provided. We aimed to describe the model of burn care that we used to calculate the charges incurred during the acute phase until discharge, so it could be reproduced and applied in other burn centres, which would facilitate a future objective comparison of the expenses in burn care. METHODS All patients admitted with burns during the period 2010-15 were included. We analysed clinical and economic data from the daily burn scores during the acute phase of the burn until discharge from the burn centre. RESULTS Total median charge/patient was US$ 28 199 (10th-90th centiles 4668-197 781) for 696 patients admitted. Burns caused by hot objects and electricity resulted in the highest charges/TBSA%, while charges/day were similar for the different causes of injury. Flame burns resulted in the highest mean charges/admission, probably because they had the longest duration of stay. Mean charges/patient increased in a linear fashion among the different age groups. CONCLUSION Our intervention-based estimate of charges has proved to be a valid tool that is sensitive to the procedures that drive the costs of the care of burns such as large TBSA%, intensive care, and operations. The burn score system could be reproduced easily in other burn centres worldwide and facilitate the comparison regardless of the differences in the currency and the economic circumstances.

Abstract
BACKGROUND Mixed partial thickness burns are the most common depth of burn injury managed at a large Australian paediatric hospital specialty burns unit. Prolonged time until re-epithelialisation is associated with increased burn depth and scar formation. Whilst current wound management approaches have benefits such as anti-microbial cover, these are not without inherent limitations including multiple dressing changes. The Biobrane® RECELL® Autologous skin Cell suspension and Silver dressings (BRACS) trial aims to identify the most effective wound management approach for mixed partial thickness injuries in children. METHODS All children presenting with an acute burn injury to the study site will be screened for eligibility. This is a single-centre, three-arm, parallel group, randomised trial. Children younger than 16 years, with burns ≥ 5% total body surface area involving any anatomical location, up to 48 h after the burn injury, and of a superficial partial to mid-dermal depth, will be included. A sample size of 84 participants will be randomised to standard silver dressing or a Regenerative Epithelial Suspension (RES™) with Biobrane® or Biobrane® alone. The first dressing will be applied under general anaesthesia and subsequent dressings will be changed every 3 to 5 days until the wound is ≥ 95% re-epithelialised, with re-epithelialisation time the primary outcome. Secondary outcomes of acute pain, acute itch, scar severity, health-related quality of life, treatment satisfaction, dressing application ease and healthcare resource use will be assessed at each dressing change and 3, 6 and 12 months post-burn injury. DISCUSSION The findings of this study can potentially change the wound management approach for superficial partial to mid-dermal burns in children locally and worldwide. TRIAL REGISTRATION The Australian New Zealand Clinical Trials Registry (ACTRN12618000245291) approved prospective registration on 15 February 2018.

Abstract
Background Silver sulfadiazine (AgSD) is widely employed as an antibacterial agent for surface burn management. However, the antibacterial activity of AgSD was restrained because of the lower drug solubility and possible cytotoxicity. Objective This study aimed to formulate stable silver sulfadiazine/nanosuspensions (AgSD/NSs) with improved AgSD solubility and prepare a suitable carrier for AgSD/NS delivery. Nanotechnology was used to overcome the low drug dissolution rate of AgSD, while the new carrier loaded with AgSD/NS was assumed to decrease the possible cytotoxicity, enhance antibacterial activity, and promote wound healing. Methods AgSD/NSs were prepared by high pressure homogenization method. Poloxamer 407-based thermoresponsive hydrogels were prepared by cold method as carriers of AgSD/NS to obtain AgSD/NS-loaded thermoresponsive hydrogel. Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) were used to measure the physicalchemical properties of AgSD/NSs and AgSD/NS-loaded gel. The cytotoxicity of the AgSD/NS-loaded gel was evaluated using methyl thiazolyltetrazolium assay with L929 mouse fibroblast cell lines. In vitro antibacterial activities of AgSD/NSs and AgSD/NS loaded gel were also measured. Results Stable AgSD/NSs with an average particle size of 369 nm were formulated while 1.5% P407 was selected as a stabilizer. The optimized AgSD/NS thermoresponsive hydrogel exhibited the gelation temperature of approximately 30°C. A significant improvement in solubility was observed for AgSD nanoparticles (96.7%) compared with AgSD coarse powders (12.5%). The results of FTIR and XRD revealed that the physicochemical properties of AgSD/NS were reserved after incorporating into the hydrogel. The cell viability after incubation with AgSD/NS-loaded thermoresponsive hydrogel improved from 60.7% to 90.6% compared with incubation with AgSD/NS directly. Drug release profiles from the thermoresponsive hydrogel increased compared with the commercial AgSD cream, implying less application frequency of AgSD cream clinically. In vitro antibacterial studies manifested that AgSD nanocrystallization significantly enhanced the antibacterial activity compared with the AgSD coarse powder. Conclusion The combination of AgSD nanosuspensions and thermoresponsive hydrogel effectively improved the AgSD antibacterial activity and decreased the cytotoxicity. This study also suggested that a poloxamer thermoresponsive hydrogel could be used as a delivery system for other nanocrystals to decrease possible nanotoxicity.

Abstract
Composition and architecture of scaffolds are the most important factors determining the performance of skin substitutes. In this work, morphology induced unique physical and biological characteristics of compatibilized TPU-PDMS blend scaffolds at 90:10, 80:20, and 70:30 blend ratios of TPU and PDMS was studied. The fiber morphology, porosity, surface wettability, and mechanical properties of electrospun scaffolds were distinctly influenced by the presence of PDMS. Interestingly, the scaffold architecture varied from electrospun fibers to porous fibers and finally occurrence of unique porous beads noticed at 30% PDMS in the microstructure which was confirmed using FESEM. Micro-CT analysis revealed that the porosity of electrospun scaffolds was enhanced from 61% to 79% with 30 parts of PDMS addition. Moreover, MTT assay and cell proliferation were studied using human skin fibroblast cells and found to be significantly enhanced with the PDMS percentage. TPU-PDMS blends offer better overall performance at 70:30 blend ratio of TPU and PDMS (T70P30). Only 4% of hemolysis was observed for T70P30 blends, which establishes the hemocompatibility of the material. In comparison, the results reveal the potential of the cytocompatible T70P30 scaffold for the fabrication of skin substitutes for tissue engineering applications. © 2018 Wiley Periodicals, Inc.

Microbial cellulose dressing compared with silver sulphadiazine for the treatment of partial thickness burns: A prospective, randomised, clinical trial. Burns 2018; 44:1982-1988. [PMID: 30005989 DOI: 10.1016/j.burns.2018.06.007] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2017] [Revised: 05/23/2018] [Accepted: 06/16/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND The current treatment for partial thickness burns at the trial site is silver sulphadiazine, as it minimises bacterial colonisation of wounds. Its deleterious effect on wound healing, together with the need for repeated, often painful, procedures, has brought about the search for a better treatment. Microbial cellulose has shown promising results that avoid these disadvantages. The aim of this study was therefore to compare microbial cellulose with silver sulphadiazine as a dressing for partial thickness burns. METHOD All patients who presented with partial thickness (superficial and deep dermal) burns from October 2014 to October 2016 were screened for this randomised clinical trial. Twenty patients were included in each group: the cellulose group was treated with microbial cellulose sheets and the control group with silver sulphadiazine cream 10mg/g. The wound was evaluated every third day. Pain was assessed using the Face, Legs, Activity, Cry, Consolability (FLACC) scale during and after each procedure. Other variables recorded were age, sex, percentage total body surface area burned (TBSA%), clinical signs of infection, time for epithelialisation and hospital stay. Linear multivariable regression was used to analyse the significance of differences between the treatment groups by adjusting for the size and depth of the burn, and the patient's age. RESULTS Median TBSA% was 9% (IQR 5.5-12.5). The median number of dressing changes was 1 (IQR 1-2) in the cellulose group, which was lower than that in the control group (median 9.5, IQR 6-16) (p<0.001). Multivariable regression analysis showed that the group treated with microbial cellulose spent 6.3 (95% CI 0.2-12.5) fewer days in hospital (p=0.04), had a mean score that was 3.4 (95% CI 2.5-4.3) points lower during wound care (p<0.001), and 2.2 (95% CI 1.6-2.7) afterwards (p<0.001). Epithelialisation was quicker, but not significantly so. CONCLUSION These results suggest that the microbial cellulose dressing is a better first choice for treatment of partial thickness burns than silver sulphadiazine cream. Fewer dressings of the wound were done and, combined with the low pain scores, this is good for both the patients and the health care system. The differences in randomisation of the area of burns is, however, a concern that needs to be included in the interpretation of the results.

Abstract
Burns are a leading cause of injury in children. Management principles vary widely, with no consensus about the best treatment. The purpose of this study was to compare outcomes of three different dressings for pediatric partial-thickness scald burns. A retrospective, single-center study was conducted for patients 0–16 years old with a diagnosis of acute partial-thickness scald burn between July 2007 and December 2012. Data regarding prehospital, inpatient, and outpatient course were collected. Cohort was stratified into topical antimicrobial (TA) ointment, silver sulfadiazine (SS), and biosynthetic dressing (BD) groups for analysis. The primary outcome of interest was time to full healing. One hundred and seventy-seven patients met all study criteria. Overall, mean total body surface area burned was 8.3 per cent. TAwas used in 24 per cent cases, SS in 32 per cent, and BD in 44 per cent. The groups were comparable in terms of presenting burn characteristics and hospital course with the exception of the BD group being associated with greater extent of injury. Patients treated with SS had a significantly longer time to full healing and increased requirement of compression garments for scar therapy. Based on these data, the authors have amended their practice and presently use BD or TA dressings to improve healing.

Abstract
The objective of this article is to investigate adherence to reporting standards and methodological quality in systematic reviews on burns care published in peer-reviewed journals to determine their utility for guiding evidence-based burns care. PubMed, Embase, Database of Abstracts of Reviews of Effects, Cochrane Database of Systematic Reviews, and the Joanna Briggs Institute (JBI) Database of Systematic Reviews and Implementation Reports were searched from 2009. Any systematic review on any question on therapeutic interventions in burns care was eligible for inclusion. Critical appraisal and data extraction were performed using the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) tool and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist by two independent reviewers. The overall quality of the 44 included burns care systematic reviews was low, with an average methodological quality of 55% and an average compliance with reporting guidelines of 70%. Correlation analysis showed that adherence to reporting guidelines has been relatively stable, but methodological quality has deteriorated (r = -.32, P < .05). Cochrane reviews had lower citation rates than reviews published in other journals, whereas reviews that included meta-analyses had more citations. Quality did not have a significant effect on citation rate. Health professionals working in burns should be able to expect that systematic reviews published in their field are of a high standard. Unfortunately, this is not the case. To address this problem, established guidelines on the conduct and reporting of systematic reviews should be adhered to by researchers and editors.

Abstract
Burn wounds disrupt the body's primary defense against invasion and colonization by microorganisms. Topical antimicrobials are one component in burn wound care. These agents suppress microbial growth to advantage skin cells and wound healing. Topical antimicrobials can be divided into 2 superclasses: antiseptics and antibiotics. We review the 4 main classes of topical antiseptics (emulsifiers, acids, oxidizers, and heavy metals) and antiseptic-impregnated dressings in current clinical use and address the mechanisms, as well as the advantages and disadvantages of each antiseptic for burn wound management.

Abstract
INTRODUCTION The ideal burn dressing for children should aim to alleviate pain, decrease length of hospital stay and minimise complications such as conversion and infection. The current literature is still inconclusive with regard to the gold standard burn dressing for the paediatric population. METHODS We retrospectively reviewed children with superficial partial thickness burns admitted to our paediatric burns unit from January 2014 to April 2015. A total of 30 patients were included in our study, of whom 13 had Biobrane® dressing. The remaining 17 patients were treated with conventional silver foam dressing (i.e. Biatain® Ag) and served as matched controls. Long-term follow-up scar evaluation was carried out at an average interval of two years after injury. RESULTS In the Biobrane group, the length of hospital stay was significantly shorter (Biobrane vs. silver foam: 4.76 ± 2.64 days vs. 8.88 ± 5.09 days; p = 0.01) and the infection rate was significantly lower (Biobrane vs. silver foam: 0% vs. 35.3%; p = 0.02). The Biobrane group had no hypergranulation or wound infection and did not require skin grafting. Long-term follow-up scar evaluation did not reveal any statistical difference between the patient groups at the two-year interval. CONCLUSION Paediatric patients with partial thickness burns treated with Biobrane dressing had shorter hospital stay and lower incidence of infection compared to those treated with conventional silver foam dressing. Biobrane and silver foam dressings did not demonstrate any significant difference in terms of long-term scar outcomes over an average follow-up duration of two years.

Abstract
The importance of skin to survival, and the devastating physical and psychological consequences of scarring following reparative healing of extensive or difficult to heal human wounds, cannot be disputed. We discuss the significant challenges faced by patients and healthcare providers alike in treating these wounds. New state of the art technologies have provided remarkable insights into the role of skin stem and progenitor cells and their niches in maintaining skin homeostasis and in reparative wound healing. Based on this knowledge, we examine different approaches to repair extensive burn injury and chronic wounds, including full and split thickness skin grafts, temporising matrices and scaffolds, and composite cultured skin products. Notable developments include next generation skin substitutes to replace split thickness skin autografts and next generation gene editing coupled with cell therapies to treat genodermatoses. Further refinements are predicted with the advent of bioprinting technologies, and newly defined biomaterials and autologous cell sources that can be engineered to more accurately replicate human skin architecture, function and cosmesis. These advances will undoubtedly improve quality of life for patients with extensive burns and difficult to heal wounds.

Wasiak J, Tyack Z, Ware R, Goodwin N, Faggion CM. Poor methodological quality and reporting standards of systematic reviews in burn care management. Int Wound J 2017; 14:754-763. [PMID: 27990772 PMCID: PMC7949759 DOI: 10.1111/iwj.12692] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2016] [Accepted: 11/02/2016] [Indexed: 12/18/2022] Open
Abstract
The methodological and reporting quality of burn-specific systematic reviews has not been established. The aim of this study was to evaluate the methodological quality of systematic reviews in burn care management. Computerised searches were performed in Ovid MEDLINE, Ovid EMBASE and The Cochrane Library through to February 2016 for systematic reviews relevant to burn care using medical subject and free-text terms such as 'burn', 'systematic review' or 'meta-analysis'. Additional studies were identified by hand-searching five discipline-specific journals. Two authors independently screened papers, extracted and evaluated methodological quality using the 11-item A Measurement Tool to Assess Systematic Reviews (AMSTAR) tool and reporting quality using the 27-item Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Characteristics of systematic reviews associated with methodological and reporting quality were identified. Descriptive statistics and linear regression identified features associated with improved methodological quality. A total of 60 systematic reviews met the inclusion criteria. Six of the 11 AMSTAR items reporting on 'a priori' design, duplicate study selection, grey literature, included/excluded studies, publication bias and conflict of interest were reported in less than 50% of the systematic reviews. Of the 27 items listed for PRISMA, 13 items reporting on introduction, methods, results and the discussion were addressed in less than 50% of systematic reviews. Multivariable analyses showed that systematic reviews associated with higher methodological or reporting quality incorporated a meta-analysis (AMSTAR regression coefficient 2.1; 95% CI: 1.1, 3.1; PRISMA regression coefficient 6·3; 95% CI: 3·8, 8·7) were published in the Cochrane library (AMSTAR regression coefficient 2·9; 95% CI: 1·6, 4·2; PRISMA regression coefficient 6·1; 95% CI: 3·1, 9·2) and included a randomised control trial (AMSTAR regression coefficient 1·4; 95%CI: 0·4, 2·4; PRISMA regression coefficient 3·4; 95% CI: 0·9, 5·8). The methodological and reporting quality of systematic reviews in burn care requires further improvement with stricter adherence by authors to the PRISMA checklist and AMSTAR tool.
