Observation on the efficacy of 1565-nm non-ablative fractional laser combined with compound betamethasone topical application on the treatment of early scar in Chinese patients. Lasers Med Sci 2022; 37:2947-2953. [PMID: 35482129 DOI: 10.1007/s10103-022-03564-6] [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] [Accepted: 04/18/2022] [Indexed: 10/18/2022]
Abstract
The objective of the study was to evaluate the efficacy of combining 1565-nm non-ablative fractional laser with low-dose compound betamethasone topical application in the treatment of immature early red hypertrophic scar. We enrolled 38 cases of patients who had immature red hypertrophic scar due to surgery or trauma which are all less than 6 months old. About 28 patients were assigned to the treatment group, and 10 patients were assigned to the control group. The patients in the treatment group were all treated with 1565-nm non-ablative fractional laser with the following parameters: spot size 10-16 mm, round or square-shaped according to lesional morphology, fluence 20-35 mJ/cm2, and density 150-200 microspot/cm2. The treated area was then applied immediately with low-dose compound betamethasone through topical application. Treatment cycles were repeated every month for a total 5 months. Photos were taken before the start of the treatment, and then monthly after. Vancouver Scar Scale score was used to evaluate the scar changes; all the patients were followed up for 3 more months after the last treatment. All side effects were documented. The patients in the control group received no treatment at all. All the parameters were recorded as the same as the treatment group. The total VSS score after the combination therapy is 0.96 ± 1.53, which in comparison with prior treatment VSS score 8.86 ± 1.43, showed a significant reduction following the treatments (P < 0.001). The control group without any treatment shows VSS score 7.10 ± 0.99 at the end of the study vs VSS score 7.70 ± 0.82 at the start of the study (P > 0.05). The patient satisfaction rate reaches 89.2% after treatment, The major side effects reported include 3 patients with post-inflammatory hyperpigmentation (10.7% of patients in the treatment group), and other minor discomfort such as transient warmth, erythema, and swelling of treatment sites. The combination approach using 1565-nm non-ablative laser and low dose of local application of compound betamethasone can effectively improve the immature red hypertrophic scar with no significant side effects; this should provide our practitioners with a new weapon in fighting those hard-to-manage early scar formations.

Abstract
BACKGROUND Burn scar and alopecia on hair-bearing areas can severely affect the social life of patients. Unlike healthy skin, poor biological and mechanical properties of scar tissue in the recipient area can reduce the survival rate of hair graft following hair transplantation. OBJECTIVES The authors sought to determine if combined non-ablative fractional laser (NAFL) and microfat injection could improve the survival rate of hair grafts on post burn scar. METHODS Thirteen patients with alopecia resulting from burn scar in hair-bearing areas of the scalp and face were treated with combined NAFL and microfat graft and subsequent follicular unit extraction hair transplantation. Cicatricial alopecia occurred on the scalp, eyebrow, mustache, and beard areas. Patients were treated with 3 to 6 sessions of NAFL and 2 to 5 sessions of microfat graft injections, followed by 1 session of hair transplantation employing the follicular unit extraction technique. RESULTS Hair transplantation was successfully performed with good to excellent results. The survival rate of transplanted follicular units ranged from 76% to 95% (mean, 85.04%), and the density success rate per square centimeter ranged from 76.9% to 95.2% (mean, 84.54%). All patients expressed high satisfaction with the results and no complication was encountered. CONCLUSIONS Hair transplantation, after combined NAFL and microfat injection, is a promising treatment for post burn alopecia. LEVEL OF EVIDENCE: 4

Abstract
BACKGROUND The occurrence of thyroid cancer has increased dramatically, and postoperative scars are placed at easily visible locations. Many patients show stronger desire for scar prevention. So far, numerous approaches have been discussed for the treatment of scars; this study is conducted to verify whether the early application of combined therapy contributes to minimal scar formation. METHODS Between March 2019 and December 2019, total of 64 patients with thyroidectomy scars of a size greater than 4.5 cm located on the anterior neck were enrolled in this prospective pilot study. Subjective and objective evaluation were carried out using the Patient and Observer Scar Assessment Scale (POSAS) at one, two, and six months after operation. Results were compared between a treatment group and a non-treatment group. RESULTS In PSAS score, the mean values of pain, itching sensation, pliability, thickness, and relief were significantly higher in the laser and steroid treatment group (p = 0.009, p = 0.000, p = 0.013, p = 0.002, and p = 0.007). The value of color of the scars showed no significant differences (p = 0.504). In OSAS score, parameter of thickness, relief, and surface area score was significantly higher score in the combination group (p = 0.029, 0.035, and 0.020), while vascularity, pigmentation, and pliability were not significantly different between two groups (p = 0.548, p = 0.983, and p = 0.128). CONCLUSION This study demonstrates that early combination therapy contributes to scar improvement to a meaningful extent based on POSAS. We believe that the combined therapy has a synergy effect on scar management, which improves the patients' quality of life in relation to their postoperative scars.

Abstract
Recent advances in laser technology allowed the development of systems that improve texture, appearance and pliability of skin in acne scars (AS). Currently, comprehensive comparative studies on the efficacy of the most commonly used fractional systems in AS are lacking. Thus, the aim of this work was to appraise and compare the clinical response to erbium versus CO2 lasers in AS in the form of a meta-analysis. The databases MEDLINE, EMBASE, Cochrane library were searched. Main clinical outcomes were investigator-reported scar improvement and participant-reported scar improvement. Five studies were included in this meta-analysis. Scar improvement was similar for both types of laser in terms of investigator-reported scar improvement (RR: 0.60 95 % CI: 0.35-1.02) and participant-reported scar improvement (RR: 0.99 95 % CI: 0.79-1.25). A sensitivity analysis that excluded studies with high risk of bias found the CO2 lasers to be superior to the erbium lasers (RR: 0.47 95 % CI: 0.24-0.93): However, the subgroup analysis showed the CO2 laser not to be significantly different from either the non-ablative erbium (RR: 0.65 95 % CI: 0.34-1.24) or the ablative erbium laser (RR: 0.60 95 % CI: 0.35-1.02). The CO2 laser produced a slightly greater clinical response compared to the erbium lasers based on the physician's assessment. Overall, the two devices do not differ largely in terms of efficacy but may be complementary, with each resurfacing laser better suited for different clinical tasks.

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 AND OBJECTIVES Recently, there have been several attempts to apply the laser therapy to hypertrophic scars (HTS). In particular, the fractional laser is in the spotlight for its usefulness in rapid wound healing and dermal remodeling. However, most previous studies have focused on the ablative fractional laser (AFL), and there are no studies on the mechanism of the nonablative fractional laser (NAFL) effect in HTS treatment. In this study, we aimed to evaluate the changes in histology and molecular chemistry to provide scientific evidence for the early treatment of HTS with NAFL. STUDY DESIGN/MATERIALS AND METHODS A total of 40 hypertrophic burn scars were made on the abdomens of two female pigs. After epithelialization, the HTS were randomly subdivided into four groups-control, AFL, NAFL (low energy), and NAFL (high energy). Laser treatment was initiated 1 week after the crust fell and the epithelium became covered, and it was repeated for six sessions over an interval of 2 weeks. Five excisional biopsies were obtained for histologic analysis and biomarker assessment. RESULTS Histologically, dermal remodeling with thin coil-shaped collagen fibers was observed in the NAFL groups. It also showed a significant increase of matrix metalloproteinase-2 (MMP-2) and Decorin at 16 weeks in an enzyme-linked immunosorbent assay. The reverse-transcription polymerase chain reaction analysis showed a tendency that high-pulse energy of NAFL led to higher messenger RNA expression than did the low-energy group. CONCLUSION The NAFL-treated groups showed characteristic collagen re-arrangement and a significant increase in MMP-2 and Decorin. These molecular changes suggest that MMP-2 and Decorin play a significant role in dermal remodeling. Early NAFL treatment for HTS could be supported with both histological and molecular evidence.

Abstract
Despite various modalities used for treating acne scars, no single treatment modality was significantly satisfactory. We compare the efficacies of fractional Erbium: yttrium aluminum garnet (Er:YAG), 2940 nm, laser versus long-pulsed Neodymium: yttrium-aluminum-garnet (Nd:YAG), 1064 nm, laser for the treatment of acne scars. Twenty patients were treated in a randomized split-face manner. They underwent three sessions at a three-week interval. Assessment of the patient was done before each treatment and 3 months after the end of the treatment sessions. The treatment effect was evaluated objectively, according to Sharquie scores for grading scarring acne vulgaris and digital photographic assessment and subjectively, according to the patient's satisfaction. Results According to objective Sharquie scores, there were no significant differences in the response between the two types of laser used. Based on the visual analog score, there was a significantly higher score of improvement for the side irradiated with fractional Er:YAG (2940 nm) laser. Subjectively, the patients were significantly satisfied with the results on the fractional Er: YAG than on the long pulsed Nd:YAG side. Both lasers were effective, However, the improvement in appearance of acne scars was better with fractional Er:YAG laser with fewer side effects with Long Pulsed Nd:YAG laser.

Abstract
BACKGROUND Hypertrophic scarring and keloid can cause significant emotional and physical discomfort. Cosmetic appearance, functional limitations, pain and pruritus form a degree of impairment. While the etiology is not fully known, there is a wide array of treatment options, which include excision, radiation, cryotherapy, silicone gel sheeting, and intralesional injections. A relatively new modality is laser therapy. While results are promising, the number of different laser systems is substantial. This review evaluates the available evidence regarding outcomes on specific objective characteristics (i.e., erythema, pigmentation, height, and pliability) of the different laser systems. METHODS A systematic literature review was performed using MEDLINE, Cochrane Library, and EMBASE. Data on scar characteristics were extracted from scar scales Vancouver Scar Scale (VSS) and Patient and Observer Scar Assessment Scale (POSAS), and from objective measurement tools. RESULTS Heterogeneity was seen in a lot of aspects: maturity of scar, origin of scar, follow-up, and number of treatments. The fractional ablative lasers CO2 10,600 nm and Er:YAG 2940 nm were found to produce the best results regarding erythema, height, and pliability, while the flash lamp-pumped pulsed dye laser (PDL) 585 nm scored slightly below that. CONCLUSIONS Laser systems, and specifically the fractional ablative lasers CO2 and Er:YAG, improved various characteristics of excessive scarring. An overview of preferred laser modality per scar characteristic is presented. Accounting for the methodological quality and the level of evidence of the data, future research in the form of randomized trials with comparable standardized scar scales is needed to confirm these results.

Abstract
Erbium: Yttrium-aluminum-garnet laser (Er: YAG) treatment has been used in resurfacing the acne scars for a long time; however, we could not find any study reporting the recovery rates after each session of the treatment. In this study, we aimed to report the improvement rates after each session. We retrospectively analyzed the data of 35 patients with acne scars treated with fractional ablative Er: YAG laser. The patients received one to four sessions of treatment with 4-week intervals and improvement rates were recorded after each session. Data are available on request from the authors. The improvement rate of the lesions varied between 1% and 25% in 34 patients at the end of the first session, while in one patient, the improvement rate was detected as 26% to 50%. At the end of the fourth session, the rate of improvement was 26% to 50% in 14 out of 24 patients and 51% to 75% in 10 patients. None of the patients showed a 76% to 100% improvement at the end of the fourth session, whereas 48.6% of the patients were satisfied with the treatment. In patients with a high expectation of an excellent improvement, a higher number of sessions of the laser treatment and/or combination treatments with different treatment methods should be planned.

Abstract
BACKGROUND AND AIMS Fractional lasers have become increasingly popular for treating atrophic scars, but their effectiveness is limited for deeper scars. We developed a novel technique (manual fractional thermal contraction technology, MFTCT) using an ultra-pulse CO2 laser and evaluated its efficacy and safety for treating atrophic facial scars. METHODS A total of 44 patients with atrophic facial scars were treated with MFTCT every 8 weeks for 1-4 times. Overall scar improvement was assessed by photographs taken at baseline and 3 months after the last treatment according to the 4-point global assessment scale (GAS) and ECCA grading scale. Improvements in color, distortion, and texture were assessed by the modified Manchester Scar Scale and scored individually from 1 to 4. Pain degrees and adverse reactions during and after treatment were recorded. RESULTS A total of 44 patients completed the treatment and follow-ups; of them, 89% reported at least 50% overall improvement after the last treatment. The mean ECCA scores fell from 67.50 ± 23.98 to 45.68 ± 18.57 (a 32% improvement), and the change was significant (P = .000). The average score for overall improvement was 3.48. The average scores for color, distortion, and texture were 3.07 ± 0.62, 3.27 ± 0.50, and 3.52 ± 0.51, respectively. Mean pain degree score was 4.27 ± 1.04, and mean erythema duration was 28.43 ± 6.58 days. Some patients developed pigmentation for a few months that resolved with topical treatment. CONCLUSION Manual fractional thermal contraction technology has definite clinical efficacy in the treatment of atrophic facial scars with fewer adverse reactions and is worth using in the clinical setting.

Abstract
Combinations of various treatment modalities were shown to be more effective than monotherapy when treating hypertrophic scars and keloids. This study was conducted to assess the effectiveness of combination therapy with non-ablative fractional laser and intralesional steroid injection. From May 2015 to June 2017, a total of 38 patients with hypertrophic scars or keloids were evaluated. The control group of 21 patients received steroid injection alone, and 17 patients (the combined group) received 1550-nm erbium-glass fractional laser treatment and steroid injection simultaneously. The mean number of treatment sessions was statistically fewer in the combined group than in the control group (6.95 vs 5.47, P = .042). There was a significant difference in the patient's scale in the combined group (14.62 vs 22.82, P = .005); however, the observer's scale was not significantly different (17.92 vs 20.55, P = .549). The recurrence rate was 38.1% (8/21) in the control group and 35.3% (6/17) in the combined groups and showed no significant difference (P = .859). However, the mean remission period was statistically longer in the combined group (3.00 months vs 4.17 months, P = .042). Combination therapy with non-ablative fractional laser and intralesional steroid injection showed better results for the treatment of hypertrophic scars and keloids with fewer treatment sessions, better patient satisfaction, and longer remission periods.

Abstract
BACKGROUND/OBJECTIVES This trial evaluated the effectiveness and safety of Bellafill for full-face acne scar treatment. PATIENTS AND METHODS In this open-label, nonrandomized, multicenter pilot study investigating the use of polymethylmethacrylate for full-face atrophic acne scar correction, 42 adult subjects with a mean age of 43 years were treated and assessed for safety and effectiveness at Months 4 and 7. There were no hypersensitivity reactions to pretreatment skin testing or during scar treatments. RESULTS At 4 and 7 months after initial treatment, 92% and 95% of subjects, respectively, were responders with ≥1-point improvement on the 5-point Acne Scar Assessment Scale. Subjects reported very high levels of improvement on the Global Aesthetic Improvement Scale (GAIS), with 95% of subjects reporting "improved or better" at 4 months and 90% at 7 months. The outcome of the physician GAIS was also high with 92% of patients classified as "improved or better" at 4 months and 97% at 7 months. There were only 2 device-related adverse events, both mild events related to Bellafill skin test (bruising, ecchymosis). There were no serious adverse events in response to the treatment product in this short-term follow-up study. CONCLUSION Polymethylmethacrylate is effective for treating full-face acne scarring.

Abstract
BACKGROUND Modalities for atrophic acne scarring can be classified depending upon the needs they satisfy; that is, resurfacing, lifting/volumization, tightening, or surgical removal/movement of tissue that is required for correction. A plethora of treatment options have resulted from the need to treat various acne scar types, variability of responses noted in various skin types, and increasing popularity of minimally invasive modalities. Still, there is a lack of consensus guidelines on treatment or combination therapies for various clinical scenarios. OBJECTIVE This systematic review includes a critical evaluation of the evidence relevant to these modalities and various multimodality therapies. METHODS We performed a systematic literature search in Medline and EMBASE databases for studies on acne scar management. Also, we checked the reference lists of included studies and review articles for further studies. A total of 89 studies were included in our quality of evidence evaluation. RESULTS The efficacy of lasers and radiofrequency in atrophic acne scarring is confirmed by many comparative and observational studies. Other modalities can be used as an adjunct, the choice of which depends on the type, severity, and number of atrophic scars. Minimally invasive procedures, such as fractional radiofrequency and needling, provide good outcomes with negligible risks in patients with dark or sensitive skin types. CONCLUSIONS There is a lack of high-quality data. Fractional lasers and radiofrequency offer significant improvement in most types of atrophic acne scars with minimal risks and can be combined with all other treatment options. Combination therapies typically provide superior outcomes than solo treatments.
