Ma Y, Barnes SP, Chen YY, Moiemen N, Lord JM, Sardeli AV. Influence of scar age, laser type and laser treatment intervals on paediatric burn scars: a systematic review and meta-analysis. BURNS & TRAUMA 2024; 12:tkad046. [PMID: 38312741 PMCID: PMC10838059 DOI: 10.1093/burnst/tkad046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 08/24/2023] [Indexed: 02/06/2024]
Abstract
Background Laser therapy has emerged to play a valuable role in the treatment of paediatric burn scars; however, there is heterogeneity in the literature, particularly concerning optimal timing for initiation of laser therapy. This study aims to investigate the effect of factors such as scar age, type of laser and laser treatment interval on burn scar outcomes in children by meta-analysis of previous studies. Methods A literature search was conducted across seven databases in May 2022 to understand the effects of laser therapy on burn scar outcomes in paediatric patients by metanalysis of standardized mean difference (SMD) between pre- and post-laser intervention. Meta-analyses were performed using the Comprehensive Meta-Analysis software version 4.0. Fixed models were selected when there was no significant heterogeneity, and the random effects model was selected for analysis when significant heterogeneity was identified. For all analyses, a p-value < 0.05 was considered significant. Results Seven studies were included in the meta-analysis with a total of 467 patients. Laser therapy significantly improved Vancouver Scar Scale (VSS)/Total Patient and Observer Scar Assessment Scale (Total POSAS), vascularity, pliability, pigmentation and scar height of burn scars. Significant heterogeneity was found between the studies and thus subgroup analyses were performed. Early laser therapy (<12 months post-injury) significantly improved VSS/POSAS scores compared to latent therapy (>12 months post-injury) {SMD -1.97 [95% confidence interval (CI) = -3.08; -0.87], p < 0.001 vs -0.59 [95%CI = -1.10; -0.07], p = 0.03} as well as vascularity {SMD -3.95 [95%CI = -4.38; -3.53], p < 0.001 vs -0.48 [95%CI = -0.66; -0.30], p < 0.001}. Non-ablative laser was most effective, significantly reducing VSS/POSAS, vascularity, pliability and scar height outcomes compared to ablative, pulse dye laser and a combination of ablative and pulse dye laser. Shorter treatment intervals of <4 weeks significantly reduced VSS/POSAS and scar height outcomes compared to intervals of 4 to 6 weeks. Conclusions Efficacy of laser therapy in the paediatric population is influenced by scar age, type of laser and interval between laser therapy application. The result of this study particularly challenges the currently accepted initiation time for laser treatment. Significant heterogeneity was observed within the studies, which suggests the need to explore other confounding factors influencing burn scar outcomes after laser therapy.

Abstract
OBJECTIVE To evaluate and explore the efficacy of CO2 fractional laser in treating post-burn hypertrophic scars in children through Meta-analysis. METHODS English databases (PubMed, Web of Science and The National Library of Medicine), as well as Chinese databases (China National Knowledge Infrastructure and Wanfang Data) were searched. RevMan 5.3 software was used to data analysis. RESULTS A total of 10 pieces of literature were included, involving 413 children. Meta-analysis showed that: (1) The average Vancouver Scar Scale after surgery was significantly lower than that before surgery [weight mean difference (WMD) = -3.56, 95% confidence interval (CI):-4.53,-2.58, p < 0.001]; (2) After CO2 fractional laser, pigmentation [WMD = -0.74, 95% CI:-1.10,-0.38, p < 0.001], pliability [WMD = -0.92, 95% CI:-1.20,-0.65, p < 0.001], vascularity [WMD = -0.77, 95% CI:-1.09,-0.46, p < 0.001], height [WMD = -0.57, 95% CI:-0.95,-0.19, p < 0.001] were improved compared with those before surgery. (3) The average Visual Analogue Scale (VAS) after surgery was significantly lower than that before surgery [WMD = -3.94, 95% CI:-5.69,-2.22, p < 0.001]. (4) Both Patient and Observer Scar Assessment Scale (POSAS)-Observer [WMD = -3.98, 95% CI:-8.44,0.47, p < 0.001] and POSAS-Patient [WMD = -4.98, 95% CI:-8.09,-1.87, p < 0.001] were significantly lower than those before surgery. (5) Erythema and vesicles were the most common complications after CO2 fractional laser therapy, with an incidence of 4.09%. CONCLUSION CO2 fractional laser is beneficial to the recovery of hypertrophic scar after burn in children, and can effectively improve the scar symptoms and signs in children, with desirable clinical efficacy.

Abstract
BACKGROUND Hypertrophic scar (HS) is a common disease in plastic and cosmetic surgery, with limited treatment options, and is a challenge for clinicians. OBJECTIVES This study aimed to evaluate the efficacy of fractional carbon dioxide (CO2 ) laser combined with botulinum toxin type A (BTXA) in treating HSs in rabbit ears and to provide new strategies for treating HS. METHODS Twenty-four New Zealand white rabbits with induced HSs were randomly divided into one control and three treatment groups. After 4 weeks of modeling, BTXA (2.0 U) was injected into the HS of the BTXA and combination groups, whereas a fractional CO2 laser (combo mode, deep energy: 12.5 mJ; super energy: 90 mJ) was used in the fractional CO2 laser and combination groups. The laser treatments were repeated after 2 weeks. The HSs in the rabbit ears were observed and photographed 5 weeks after the first treatment. The scar thickness in each group was measured and compared, and the scar elevation index (SEI) was determined using hematoxylin and eosin staining. Collagen content and alignment were observed using Masson's trichrome staining. Western blotting and immunohistochemistry were performed to analyze scar-related protein levels. RESULTS Hypertrophic scars were reduced in all treatment groups compared with the control group. The combination group had lower scar thickness, SEI, and expression of scar-related proteins in HSs, with an appearance similar to that of normal rabbit ear skin. Furthermore, the fibroblast content and collagen deposition decreased significantly in the combination group (p < 0.001). CONCLUSIONS Fractional CO2 laser combined with BTXA more effectively reduced HSs by inhibiting fibroblast proliferation, decreasing transforming growth factor-β1 and α- smooth muscle actin expression, and causing collagen remodeling.

Abstract
Laser treatment has gained more and more importance in the therapy of scars during the last years. Scientific work, especially in children, is scarce on this topic and mostly with an insufficient number of cases or only subjective descriptions. Our study included 77 children from 2012 to 2022 with scars after thermal injury. These were treated at least three times or more by CO2 laser or in combination with pulsed dyed laser (PDL). Beforehand, scar texture and elasticity were determined by a skin elasticity analysis system. Regarding the subjective evaluation, a questionnaire was given to the patients or their parents. Further criteria were the Patient and Observer Scar Assessment Scale (POSAS) and Vancouver Scar Scale (VSS). A statistically significant improvement in elasticity was demonstrated in all scars of any age after each laser treatment. In addition, a significant correlation was found between the number of laser treatments and an increase in elasticity. The assessments of scars after one or more laser sessions by the observer as well as the patient showed a decreasing score in all categories with an increase in the number of laser therapies. The VSS score also improved significantly after each laser session. The mean score before treatment was about 7, after the first laser session, the mean score was already below 6 with a statistical significance. Ninety-six percent of the patients or their parents were satisfied with the laser therapy, and 90% wished to repeat the procedure. This work confirms, by means of the objectification by the scar measurement, the previous scientific works concerning a scar therapy by laser and emphasizes particularly that this can also be used without problems with children with symptomatic scars, contractures, or with cosmetically relevant scars.

Abstract
Significance: This body of work gives a concise and comprehensive overview for the clinician and scientist on the latest treatment modalities for hypertrophic scars (HTS) and keloids in the pediatric population, as well as the most promising methods of prevention currently being investigated. This review will serve as a guide to the clinician for treatment selection and as an efficient tool for the scientist to achieve a comprehensive overview of the scientific literature to guide their future experiments aimed at pathologic scar prevention. Recent Advances: Current studies in the literature suggest carbon dioxide (CO2) laser and E-light (bipolar radiofrequency, intense pulsed light, and cooling) are two of the most effective treatment modalities for HTS, while surgical excision+CO2 laser+triamcinolone injection was one of the most successful treatments for keloids. In animal models, drug impregnated electrospun nanofiber dressings offer encouraging results for HTS prevention, while Kelulut honey showed promising results for keloid prevention. Critical Issues: Treatment outcome reproducibility is hindered by small cohorts of patients, inadequate-follow up, and variability in assessment tools. Prevention studies show multiple ways of achieving the same result, yet fall short of complete prevention. Furthermore, some studies that have purported full prevention have not been validated. Future Directions: To establish a standard of care, large clinical trials of the most successful modalities in small cohorts are needed. The key for prevention will be validation in animal models of the most successful methods, followed by translational and clinical studies.

Abstract
Abstract
Post-burn pruritus is a significant issue that can have a devastating impact on patient quality of life. Despite its known negative impact, few studies have focused on the pediatric population. Thus, the aim of this study was to determine the incidence of pruritus among pediatric burn patients as well as identify its predictive factors and commonly used treatments, including the novel use of laser therapy. A retrospective analysis of all burn patients treated at our pediatric burn centre from 2009 to 2017 was conducted. The primary outcome measure was the presence or absence of pruritus at any point following the burn. One thousand seven hundred and eighty-three patients met the inclusion criteria for this study. The mean age at injury was 3.67 years (SD 4.02) and the mean burn TBSA was 3.48% (SD 4.81) with most burns resulting from scalds (66%). In total, 665 patients (37.3%) experienced pruritus. Following multivariable logistic regression, TBSA, age > 5 years, burns secondary to fire/flames, and burn depth, were identified as significant predictors of pruritus (p < 0.05). Pruritus was treated with diphenhydramine (85.0%), hydroxyzine (37.3%), and gabapentin (4.2%) as well as massage (45.7%), pressure garments (20.0%), and laser therapy (8.6%). This study addresses the knowledge gap in literature related to post-burn pruritus among pediatric patients and includes one of the largest patient cohorts published to date. Moreover, the results further contribute to our understanding of post-burn pruritus in children and may help us to predict which patients are most likely to be affected, so that treatment can be initiated as soon as possible.

Abstract
This paper outlines the protocol for a study that is being carried out at multiple centres across the UK in the next three years. It is a Research for Patient Benefit (RfPB) study funded by the National Institute for Healthcare Research (NIHR). The aim is to assess the effectiveness of treating hypertrophic burns scars with pulsed dye laser (PDL) at an early stage of scar formation. The objective is to improve Quality of Life for the patient by improving both the appearance and quality of burn scarring, as well as reducing its psychological impact. This is a parallel-arm randomised, controlled trial to compare PDL and standard care against standard care alone. The difference is measured between baseline and six-month follow-up. Recruits are within three months of healing from a burn injury; with wounds showing a defined potential for hypertrophic scarring. A total of 120 patients are recruited in a multi-centre study; with randomisation in a 1:1 allocation to each arm. The treatment arm receives 3 PDL treatments at six-week intervals in addition to standard care, whereas the control arm receives standard care alone. The primary outcome is the patient-rated part of the Patient and Observer Scar Scale (POSAS). Psychological and psycho-social impact is evaluated using the CARe burn scale (UWE, Bristol) and Quality Adjusted Life Years (QALY) is determined using the Short-Form Health Survey (SF-12). The study evaluates both the cost-effectiveness through an economic analysis and the patient-reported experience of the treatment by phone interviews.

Abstract
595-nm pulsed dye laser and fractional CO2 laser have been demonstrated effective to treat hypertrophic scar. The underlying mechanism may involve transforming growth factor-beta1 (TGFβ1) and proliferating cell nuclear antigen (PCNA), but remains to be clarified. Our study was performed to investigate how 595-nm pulsed dye laser combined with fractional CO2 laser treats hypertrophic scars in a rabbit model through regulating the expression of TGFβ1 and PCNA. Twenty-four New Zealand white rabbits were randomly divided into control group, pulsed dye laser group, fractional CO2 laser group, and pulsed dye laser + fractional CO2 laser (combination) group. Surgical wounds were made and allowed to grow into hypertrophic scars at day 28. Next, 595-nm pulsed dye laser (fluence: 15 J/cm2; square: 7 mm; pulse duration: 10 ms) was used in pulsed dye laser and combination group, while fractional CO2 laser (combo mode, deep energy: 12.5 mJ; super energy: 90 mJ) in fractional CO2 laser and combination groups, once every 4 weeks for 3 times. The appearance and thickness of hypertrophic scar samples were measured with hematoxylin-eosin and Van Gieson's straining. The expressions of TGFβ1 and PCNA were evaluated by immunohistochemical and western blot analysis. A significant improvement was noted in the thickness, size, hardness, and histopathology of hypertrophic scar samples after laser treatment, especially in combination group. Scar Elevation Index (SEI), fiber density (NA), and collagen fiber content (AA) decreased most significantly in combination group (2.10 ± 0.14; 2506 ± 383.00; 22.98 ± 2.80%) compared to 595-nm pulsed dye laser group (3.35 ± 0.28; 4857 ± 209.40; 42.83 ± 1.71%) and fractional CO2 laser group (2.60 ± 0.25; 3995 ± 224.20; 38.33 ± 3.01%) (P < 0.001). Furthermore, TGFβ1 and PCNA expressions were more suppressed in combination group (8.78 ± 1.03; 7.81 ± 1.51) than in 595-nm pulsed dye laser (14.91 ± 1.68; 15.73 ± 2.53) and fractional CO2 laser alone group (15.96 ± 1.56; 16.13 ± 1.72) (P < 0.001). The combination of 595-nm pulsed dye laser with fractional CO2 laser can improve the morphology and histology of hypertrophic scars in a rabbit model through inhibiting the expression of TGFβ1 and PCNA protein. Our findings can pave the way for new clinical treatment strategies for hypertrophic scars.

Abstract
BACKGROUND Various laser therapies have been introduced in scar management. However, pain during treatment has limited the application of laser therapy in pediatrics. OBJECTIVES To evaluate whether the use of the low-energy mode of a carbon dioxide (CO2 ) laser improves hypertrophic scars in a pediatric population. METHODS This prospective, randomized, split-scar trial was designed to assess the safety and efficacy of low-energy CO2 laser use. Patients aged <12 years with hypertrophic scars were enrolled. Each hypertrophic scar was equally divided into three parts: the two ends of each scar were randomly assigned to control and experimental groups, and the center portion was considered a transition zone and was not included in the analysis. A total of three laser treatments were performed at 1-month intervals. Scar scale scores 6 months after the final treatment was the primary outcome. Additionally, the Visual Analog Scale (VAS) was used to evaluate pain after each treatment. RESULTS Of the 23 patients enrolled, 20 completed the study. The total Patient and Observer Scar Assessment Scale (POSAS) score at the 6-month follow-up was significantly lower for the treated site (44.95 for the treated group vs. 64.85 for the control group, p < 0.0001). Both the patient and observer POSAS scores showed an obvious difference between the treated and control groups (19.95 vs. 29.95 for patient scores, respectively, p < 0.0001, and 26.00 vs. 34.90 for observer scores, respectively, p < 0.0001). All observer and patient scores describing pain, pruritus, color, stiffness, and thickness were statistically different and favored the treated site. No significant difference was found in patient score of irregularity. The average VAS therapeutic pain score was 3.5 ± 1.43 out of 10. CONCLUSIONS Low-energy CO2 fractional laser therapy improved hypertrophic scars in a pediatric population. Therefore, for children with hypertrophic scar, low-energy CO2 laser with less procedure pain may be more appropriate.

Abstract
The main therapeutic options for extensive scarring (e.g., > 20% of the total body surface area, or TBSA) after burns and trauma have focused on conservative treatments, such as compression, moisturization, and topical agent application. However, these treatments may not achieve optimal effects due to the large size and complexity of the scars. UltraPulse fractional CO2 laser treatment is a novel approach that is currently a subject of intense interest; this treatment is most widely used to improve texture, pliability, and pigmentation in all types of scars. However, no studies on the independent use of UltraPulse fractional CO2 laser treatment for extensive scars have been reported. This retrospective study evaluated a total of 21 patients, whose scars covered 20 to 65% TBSA. Scar thickness was measured by ultrasonography before treatment. Personalized treatment modalities and parameters were set according to the scar type and thickness. Scar formation and treatment effects were evaluated by photography, the Patient and Observer Scar Assessment Scale (POSAS), and patients’ judgment of effectiveness. Where the scars covered joints, joint function was assessed by measuring the maximum range of motion (ROM). With laser therapy, scars became flatter and lighter; furthermore, pruritus, pain, and discomfort decreased significantly. POSAS scores significantly decreased after laser therapy, including the item scores for pain and pruritus. There were no instances of joint contracture, ROM reduction, apparent functional impairment, serious adverse events, or comorbidities. This study demonstrates the safety and efficiency of UltraPulse fractional CO2 laser treatment for extensive scarring.

Abstract
OBJECTIVE To review the clinical and scientific literature on the subjective ways of assessing burn scars and describe their main characteristics. DATA SOURCES The Latin American, Caribbean Health Sciences Literature, Nursing Database, PubMed, CINAHL, and Scopus and Web of Science databases were used to search for studies published between 2014 and 2018 using descriptors in Portuguese, Spanish, and English. STUDY SELECTION After establishing the research question and the location and definition of the studies, as well as accounting for differences among databases and application of filters based on inclusion and exclusion criteria, 886 references remained. DATA EXTRACTION Investigators reviewed the titles and abstracts of the sample and selected 188 relevant studies for full review. DATA SYNTHESIS Twenty-six subjective forms of assessment were found; most research concerned the Patient and Observer Scar Assessment Scale and the Vancouver Scar Scale. CONCLUSIONS The Patient and Observer Scar Assessment Scale and the Vancouver Scar Scale are the most common scales for assessing burn scars and have similar evaluation points such as vascularization, pliability, pigmentation, and height, which are the main parameters that contribute to the general assessment and severity of a scar. There is a need to improve instructions for application of the scales to facilitate better understanding and improve agreement among evaluators.

Abstract
BACKGROUND Hypertrophic scars are commonly seen in children and associated with pruritus, pain, functional impairment, and aesthetic disfigurement. Ablative fractional CO2 and pulse dye laser are emerging techniques to improve scar quality. Only limited data are available on children, nonburn scars, and patient-reported outcome. We aimed to investigate safety and outcome of repeated laser therapy for hypertrophic scars originating from burns and other conditions by means of patient- and physician-reported outcome measures. METHODS This was a retrospective before-after analysis of laser treatments in children with hypertrophic scars. Outcome was measured using Patient and Observer Scar Assessment Scale, Vancouver Scar Scale and Itch Man Scale. With respect to safety, laser- and anesthesia-related complications were analyzed. RESULTS Seventeen patients, aged 11.37 ± 4.82 years with 27 scars, underwent 102 distinct laser treatments, mainly combined CO2 and pulse dye laser (94%), with few CO2 only (6%). Vancouver Scar Scale total score before the first and after the first session decreased significantly from 7.65 ± 2.12 to 4.88 ± 1.73; Patient and Observer Scar Assessment Scale observer overall opinion also dropped from 5.88 ± 1.57 to 4.25 ± 1.70. Pruritus improved significantly. Patient age and timing of laser intervention did not have an impact on treatment response. Complications related to laser treatment were seen in 2% (wound infection, n = 2) and to anesthesia in 4% (insignificant n = 2, minor n = 1). CONCLUSIONS Combined laser therapy significantly improves quality, pain, and pruritus of hypertrophic scars in children. When provided by experienced laser and anesthesia teams, it is safe with a low rate of complications.

Abstract
INTRODUCTION Carbon dioxide (CO2) laser treatment is routinely used to treat hypertrophic burn scars (HBS). Although prior research has documented subjective improvement in HBS after treatment, there is little data evaluating objective changes in scar characteristics after therapy. The aim of our process improvement project was to evaluate changes to scar thickness (ST) using high-frequency ultrasound in patients with HBS undergoing CO2 laser therapy. METHODS Ultrasound measurements of ST were obtained from patients with HBS before initial and at each subsequent treatment. ST, reduction in ST per treatment, and percentage reduction in ST from baseline were tabulated. Post hoc analyses examining the effect of initial ST and scar maturity on outcome were performed. First, patients were grouped by baseline ST into thicker (group 1, initial ST ≥ median value) and thinner (group 2, initial ST < median value) scar groups. Second, patients were divided into quartiles based on time from injury to treatment. Outcomes at each time point were compared with either Mann-Whitney U or Kruskal-Wallis tests, with Bonferonni corrections performed for post hoc subgroup analyses. Significance was set at P < 0.05. RESULTS Twenty-one consecutive patients with HBS treated with CO2 laser were included. All patients completed 1 or more treatment, 48% completed 2 or more treatments, and 28% completed 3 treatments. Median initial ST was 0.71 cm (0.44-0.98 cm), and median scar maturity was 7.5 months (4.9-9.8 months). Overall, ST decreased over the treatment course (P < 0.001), with post hoc analysis demonstrating that 2 treatments were required to achieve a significant ST reduction (P < 0.01). On subgroup analysis comparing initial ST, ST decreased significantly in group 1 (thicker scars) overall (P < 0.001) but not in group 2 (P = 0.109). ST reduction was greatest after 1 treatment in group 1 (P = 0.022) and group 2 (P = 0.061). Percent reduction was greater in group 1 relative to group 2 after 1 treatment (P = 0.016). On subgroup analysis of scar maturity, there were no significant differences in either baseline ST or ST at any subsequent visit. CONCLUSIONS Fractionated ablative CO2 laser treatment improved ST after 1 to 2 treatments. Patients with thicker scars demonstrated greater ST reduction than those with thinner scars. Ultrasound adequately assessed treatment response.

Abstract
Hypertrophic burn scars remain a significant burden for patients and a challenge for clinicians. THE AIM Assessement of the efficacy of combined Pulsed Dye Laser and Ablative Fractional CO2 Laser therapy on hyperthophic scars and correlation with plasma levels of MMP-2, TIMP-1 and alpha-1 type I collagen. PATIENTS AND METHODS Twenty five pediatric subjects were enrolled into the study. Control group consisted of age-matched subjects admitted for surgical repair of inguinal hernia. For the assessment of the results of laser treatment we used the Vancouver scar scale (VSS), and Patient-Observer Scar Assessment Scale (POSAS). We also correlated clinical results with plasma levels of MMP-2, TIMP-1 and alpha-1 type I collagen. RESULTS All subjects reported the laser treatment resulted in improvement and were somewhat satisfied or very satisfied with their experience. No adverse events were reported. The levels of MMP-2, TIMP-1 and alpha-1 type I collagen in our patients with scars before laser threatment were higher in comparison to controls. We also found statistically significant decrease in the levels of MMP-2, TIMP-1 and alpha-1 type I collagen after laser treatment of burn scars CONCLUSIONS: Our study clearly shows that combined CO2-AFL treatment for burn scars improve texture, colour, function and alleviate pruritus. We believe that decrease in the levels of MMP-2, TIMP-1 and alpha-1 type I collagen after laser treatment of burn scars, reflects reduced dynamic of scar.

Abstract
Hypertrophic scars (HTS) following burns and other trauma and are associated with significant functional and psychosocial impairment. Ablative fractional lasers (AFLs) are increasingly being applied in the treatment of HTS supported by a rapidly expanding multidisciplinary base of literature. The multidisciplinary authors sought to evaluate existing literature, provide context and identify gaps, and make recommendations for a path forward. A systematic review was conducted to identify literature pertinent literature through September 2019. Retrospective cohort, randomized controlled trials, quasi-randomized controlled trials, observational prospective cohort, or case series with five or more subjects with hypertrophic scars incurred from burns and related trauma were considered. Twenty-two of the 23 evaluated studies documented statistically significant and/or meaningful qualitative improvements in nearly all outcome measures. Adverse events were generally infrequent and minor. Significant heterogeneity was observed among the studies included in this systematic review, precluding metaanalysis of pooled data. There is abundant existing literature on the use of AFLs in the management of HTS but study heterogeneity limits generalizability. Future studies should prioritize standardized protocols including assessments of function and quality of life.

Abstract
Abstract
Fractional ablative CO2 laser is being used increasingly to treat burn scars; however, objective measures of outcome success vary widely. This systematic review and meta-analysis extracts and pools available data to assess the outcomes of patients with burn scars treated with fractional ablative CO2 laser. A search of MEDLINE, EMBASE, and the gray literature was performed. The review included studies that reported patients with a confirmed diagnosis of scarring as a result of a burn injury, who were treated with fractional ablative CO2 laser and whose progress was recorded using the Vancouver Scar Scale (VSS). Eight studies were included in the systematic review and meta-analysis. Treatment regimens varied amongst studies, as did patient outcomes. Pooled data revealed an average VSS improvement of 29% across 282 patients following fractional CO2 ablative laser treatment. Although the heterogeneity of treatment regimens across studies limits this systematic review’s ability to provide specific treatment recommendations, the overall trend towards improvement of burns scars treated with fractional CO2 laser based on the VSS encourages further exploration of this modality as a therapeutic tool.

Abstract
BACKGROUND AND OBJECTIVES Fractional ablative 10,600-nm carbon dioxide (CO2 ) laser has well-demonstrated safety and efficacy in resurfacing treatment of scars in the adult population and in the treatment of pediatric burn scars. However, there is a paucity of literature regarding laser resurfacing of traumatic and surgical scars for cosmetic benefit in the pediatric population, and in majority of cases previously reported, this was done under general anesthesia. STUDY DESIGN/MATERIALS AND METHODS This was a retrospective chart review of pediatric patients under the age of 18 who underwent fractional ablative CO2 laser resurfacing (FALR) of traumatic or surgical scars at a single center between 2018 and 2019, inclusive. Primary endpoints included safety and tolerance. RESULTS A total of 31 FALR treatments were performed in 10 patients with traumatic and surgical scars located on the face (age 4-14 years, Fitzpatrick skin type [FST] I-IV, 60% female). Settings ranged from total energy per session 0.02-0.33 kJ, with a 7-mm tip and 30-50% coverage. Nine patients had two or more treatments (average 3, maximum 8) spaced at least 4 weeks apart. All resurfacing treatments were well-tolerated with local infiltration of 1% lidocaine with epinephrine (1:100,000). Six (67%) patients were treated with additional measures including pulsed dye laser, 1927-nm fractional non-ablative low-energy, low-density laser, or intralesional agents (5-fluorouracil, triamcinolone, botulinum toxin). At follow-up (of varied intervals), short-term erythema, as expected, was seen in six patients, and hyperpigmentation in one case (FST IV), both treated with aforementioned alternate devices. Although gradual, improvement in scar appearance and texture was seen with FALR treatments. No additional scarring, infection, or hypopigmentation was seen. CONCLUSIONS Treatment with fractional ablative laser resurfacing is safe and well-tolerated in the pediatric population in an outpatient setting with local anesthesia. Traumatic scars may cause significant distress to children and parents alike. Multimodal therapy may lead to optimal cosmesis. Given the excellent tolerability, the authors recommend consideration of laser resurfacing in pediatric patients with traumatic or surgical scars when bothersome, either cosmetically or psychologically.

Abstract
PURPOSE OF REVIEW Thermal injury is a leading cause of morbidity and mortality in children. This review highlights the current management of thermal injury and its complications. RECENT FINDINGS Many recent advances in burn care have improved the outcomes of patients with thermal injury; however, variability does exist, and there are many opportunities for improvement. This review will highlight the complexity of issues encountered along the continuum of care for thermal injury patients. Accurate estimation of total burn surface area (TBSA) of a burn continues to be a challenge in pediatric patients. Variability continues to exist surrounding the management of burn resuscitation and complex wounds. Children with extensive burns have profound immune and metabolic changes that can lead to multiple complications, including infections, growth arrest, and loss of lean body mass. Standardization in measurements related to quality of life and psychological stress following pediatric thermal injury is much needed. SUMMARY The care of pediatric patients with thermal injury is complex and multifaceted. This review highlights the most recent advances in pediatric burn care.

Abstract
BACKGROUND AND OBJECTIVES There has been reports on fractional CO2 laser successfully improving contracture scars that impair the function of a joint. It seems that certain contracture problems could be solved by laser instead of surgery. However, the clinical application could be difficult when the efficacy of the method remains unknown. The purpose of this study is to report the releasing capacity of the fractional CO2 laser on contracture scars based on a defined treatment method. STUDY DESIGN/MATERIALS AND METHODS We conducted a retrospective study in patients with limited function in joints caused by contracture scars. Fractional CO2 laser and our "3D mesh releasing" protocol were applied. The primary outcome was the improvement measured in range of motion (ROM) of the relevant joint before all intervention and 6 months after the last treatment. RESULT From November 2016 to January 2018, 11 joints of 10 cases were treated by the fractional CO2 laser. Patients went through 2.27 (standard deviation [SD] 1.42, 1-5) sessions. The average progress of ROM before and 6 months after all treatments was 19.13° (SD 10.25, P < 0.02). In six cases, we recorded that there was an 8.53° (SD 5.81, P < 0.02) of increase in ROM immediately after the laser session, and the average improvement reached up to 13.58° (SD 8.15, P < 0.02) after 2-3 months during the next follow-up. CONCLUSION The fractional CO2 laser could achieve functional improvement in contracture scars and it maintained its effect for at least 6 months. The "3D Mesh Releasing" protocol would help to standardize the treatment procedure. This modality has minimal-invasiveness and potentially could become a supplement to the current treatment choices for mild contracture scars. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

Abstract
Despite the increasing knowledge about wound healing mechanisms and the advancements made in laser technology, hypertrophic scars remain difficult to manage. This review intends to discuss the laser devices studied in the prevention and treatment of HS, arising from trauma, surgery, and burns, detail their mechanisms of action, and emphasize those devices with the most promising effects. Most of the suggested mechanisms and explanations for the use of lasers in treating hypertrophic scars are based on selective photothermolysis, in which the light energy emitted from a laser is absorbed by its intended target, thereby disrupting existing collagen and altering the cycle of neocollagenesis. Through our literature review, we have determined that combination therapies, utilizing more than one laser target demonstrate enhanced clinical efficacy. Further, early use of laser devices has been shown to enhance the cosmetic result of sutured wounds and may play a role in preventing the development of hypertrophic scars.

Abstract
Carbon dioxide ablative fractional laser (CO2-AFL) therapy has not been widely adopted in pediatric burn care given limited outcomes literature and no established guidelines on laser treatment protocols. We present our experience to further elucidate the clinical role of CO2-AFL therapy for pediatric hypertrophic burn scars. We conducted a prospective cohort study of pediatric burn patients undergoing CO2-AFL treatment of hypertrophic, symptomatic burn scars at a tertiary care regional burn center during a 2-year period. Scars were assessed before each treatment using the Patient and Observer Scar Assessment Scale (POSAS), a validated, subjective, comprehensive scar assessment tool. We treated 49 pediatric patients for a total of 180 laser sessions. Burn severity was full thickness (63.6%) or deep partial thickness (47.7%). Observer-rated POSAS scores revealed statistically significant improvements in pigment, thickness, relief, pliability, and surface area after one treatment with continued improvement until the last laser session. Patient-rated POSAS revealed statistically significant improvements in color, stiffness, thickness, and irregularity after laser treatments. Total POSAS improved from 89.6 ± 17.5 to 76.6 ± 16.8 (P < .0001) after one treatment with further improvement to 69.2 ± 14.9 (P < .0001) at the final laser session. We found convincing evidence that CO2-AFL therapy improves hypertrophic burn scars on both patient- and observer-rated scales confirming statistical and clinical significance to both providers and families. These findings demonstrate that CO2-AFL can improve hypertrophic burn scars in pediatric patients providing a lower risk alternative to invasive therapies and a more immediate, efficacious alternative to more conservative scar treatments.
