[PMID: 38489702 PMCID: PMC10939677 DOI: 10.1097/md.0000000000037329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 01/26/2024] [Accepted: 01/31/2024] [Indexed: 03/17/2024] Open
Abstract
To evaluate the impact of CO2 fractional laser combined with recombinant human epidermal growth factor (rhEGF) gel on skin barrier in acne scar patients. In a retrospective analysis, we examined 105 acne scar patients admitted between July 2018 and August 2021. Of these, 51 received only CO2 fractional laser (control group), while 54 underwent a combination of CO2 fractional laser and rhEGF gel (observation group). We assessed treatment efficacy, symptom relief, skin barrier parameters, pre- and posttreatment inflammatory factors, adverse reactions, posttreatment quality of life, and patient satisfaction. The observation group exhibited a higher overall response rate, significantly shorter wound healing, scab formation, and scab detachment times. Additionally, this group showed increased stratum corneum water content, decreased pH, and transdermal water loss (TEWL), and reduced hypersensitive C-reactive protein and interleukin-6 expression posttreatment. Quality of life scores were higher, with fewer adverse reactions and greater treatment satisfaction. Combining CO2 fractional laser with rhEGF gel markedly improves acne scar treatment efficacy, enhances skin barrier function, reduces inflammation, and elevates quality of life. Its safety profile supports its broader clinical adoption.

Abstract
A meta-analysis was performed to investigate the efficacy of ultrapulse carbon dioxide dot matrix laser treatment for patients with facial scars. PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure, China Biomedical Literature Database, and Wanfang Database were systematically searched for randomised controlled trials (RCTs) investigating ultrapulse carbon dioxide dot matrix laser treatment for facial scars, and the search was conducted from the time of database inception to July 2023. The retrieved literature was screened independently by two researchers, and data extraction and quality assessments were performed. The meta-analysis was conducted using RevMan 5.4 software. Outcome metrics included overall treatment effectiveness, complication rate, and Echelle d'évaluation clinique des cicatrices d'acné (ECCA) scores. Seventeen RCTs comprising 3703 patients were included, with 1853 patients in the experimental group and 1850 in the control group. The results showed that the experimental group had significantly increased overall treatment efficacy rates (odds ratio [OR]: 3.84, 95% confidence interval [CI]: 3.02-4.90, p < 0.001), reduced complication rates (OR: 0.35, 95% CI: 0.27-0.44, p < 0.001), and improved ECCA scores (standardised mean difference: -1.79, 95% CI: -2.53 to -1.05, p < 0.001) compared with the control group. In conclusion, as the primary treatment modality for facial acne depression scars, ultrapulse carbon dioxide dot matrix laser can significantly increase the overall treatment efficacy rate and ECCA scores and reduce the incidence of complications; however, higher-quality studies are needed for further validation.

Abstract
Objective Noise pollution has been listed as one of the three major types of pollution, along with air and water pollution. Hospitals should pay attention to noise control, which is of great importance for the treatment and rehabilitation of patients. This study focuses on the application value of noise control and relaxation training. Methods This study retrospectively collected and analyzed the clinical data of 184 patients who underwent skin laser cosmetology in Ningbo Yinzhou No. 2 Hospital from January 2021 to December 2022. Twelve patients who did not meet the criteria were excluded, and the remaining 172 patients were divided based on the type of intervention into the control group (CG, n = 82) and the study group (SG, n = 90). The CG received relaxation training and routine noise management, while the SG received noise control combined with relaxation training. The intervention effect was discussed from the aspects of noise, psychology, and satisfaction. Results After the intervention, the SG had overtly lower noise levels and lower scores of anxiety and depression compared to the CG (all P < 0.001). Correlation analysis showed that noise levels were positively correlated with scores of anxiety and depression (r = 0.553, r = 0.592, P < 0.001). The two groups had no significant difference in total satisfaction (P > 0.05). Conclusion Noise poses a significant threat to the human body. Strengthening noise control in hospitals is beneficial for patients' recovery. Combining noise control with relaxation training is an intervention method worthy of clinical application. It can improve the hospitalization environment and reduce the noise levels to a great extent, thereby improving the psychological state of patients and enhancing the medical satisfaction.

Abstract
Fractional CO2 laser, as a typical ablative laser, has been used to assist in the treatment of many skin diseases, such as photoaging, atrophic scar, hypertrophic scar, superficial pigmentation, vitiligo, and so on. However, the dynamic changes in skin function after fractional CO2 laser treatment are still unclear. This study explored the changes in local skin function and possible regulatory mechanisms after fractional CO2 laser treatment for 1, 3, 5, and 7 days through transcriptome high-throughput sequencing. The results showed that fractional CO2 laser tended to transform the "lesions" into "normal skin", regulate the skin barrier, coordinate the rearrangement of collagen, enhance the local microvascular circulation, activate the immune system to secrete a large number of cytokines, and act as an auxiliary tool to assist drug transport. In conclusion, according to the basic principle of destruction before reconstruction, fractional CO2 laser plays a key role of balancer in skin reconstruction.

Abstract
BACKGROUND Acne vulgaris (AV) is the most pervasive inflammatory disease of hair follicle and sebaceous gland in the dermatology department, and depressed scar (DS) is the most common and serious sequela of AV. AIMS To explore the clinical value of CO2 dot matrix laser combined with platelet-rich plasma (PRP)-treated AV. METHODS Total 81 patients with DS at the rear of AV from December 2018 to October 2019 were selected, randomly divided into observation group (OG, n = 39) and control group (CG, n = 42). Patients in the OG group were treated with CO2 dot matrix laser combined with PRP, and those in the CG group were treated with CO2 dot matrix laser. To observe clinical outcomes in both groups. RESULTS According to experimental analysis, compared with the CG group, CO2 dot matrix laser combined with PRP can more strongly improve the clinical efficacy on patients, shorten the scar scabbing time and decrustation time, more effectively contributed to their scar repair, comfort, skin condition, psychological state and satisfaction, and reduced their pain. The subsequent follow-up results also showed that patients in the OG group experienced better quality of life. Moreover, according to the logistic regression analysis, the course of disease, scar degree, and staying up late were independent risk factors for the repair effect, and the repair method of CO2 dot matrix laser combined with PRP was an independent protection factor. CONCLUSION To sum up, CO2 dot matrix laser combined with PRP can strongly enhance the scar repair effect, psychological state, and life quality of patients with DS after AV, so it is worth popularizing in clinical practice.

Ablative fractional carbon dioxide laser combined with autologous platelet-rich plasma in the treatment of atrophic acne scars: A systematic review and meta-analysis. Dermatol Ther 2022; 35:e15888. [PMID: 36183145 DOI: 10.1111/dth.15888] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Revised: 09/07/2022] [Accepted: 09/29/2022] [Indexed: 11/29/2022]
Abstract
Atrophic acne scars are the most common cutaneous seqaule of acne vulgaris, representing 80%-90% of all acne scars. Ablative fractional carbon dioxide (FCO2 ) laser is the gold standard treatment for atrophic scars. Additionally, platelet-rich plasma (PRP) is suggested to accelerate the healing process and collagen synthesis. The aim of the present systematic review and meta-analysis was to determine the efficacy and safety of PRP combined with Ablative FCO2 laser in the treatment of moderate to severe atrophic acne scars. Randomized controlled trials (RCTs) that have compared PRP in combination with ablative FCO2 laser to ablative FCO2 laser alone with respect to the efficacy and safety measures were included. We have systematically explored Embase, Medline, and CENTRAL databases via Ovid. The outcomes that our systematic review sought to evaluate were clinical improvement, patient satisfaction, and Goodman and Baron's qualitative acne scar score. The dichotomous outcomes were presented as odds ratio (OR) while the continuous outcomes were presented as standardized mean difference (SMD). Eleven RCTs that represents 313 participants were included. The combined use of laser and PRP showed a statistically significant clinical improvement and patient satisfaction compared to the use of laser alone (OR = 2.56, 95% CI 1.37-4.78 and OR = 3.38, 95% CI 1.80-6.34, respectively). Also, a significant improvement in Goodman and Baron's score was achieved by combining PRP with laser (SMD = -0.40, 95% CI -0.65 to -0.14). The combined treatment of laser and PRP was highly synergistic, effective, and safe in treating moderate to severe atrophic acne scars.

Abstract
Purpose To investigate the efficacy of skin wound tension reduction device (SWTRD) combined with ablative fractional carbon dioxide laser (CO2-AFL) for the prevention of scar formation following the excision of facial cutaneous lesions in children. Methods Patients undergoing surgical excision of facial cutaneous lesions in our hospital between May 2019 and April 2021 were enrolled. After the excision of facial cutaneous lesions and based on the personal intents and conditions, patients were assigned to undergo SWTRD combined with CO2-AFL. Outcome evaluations were as follows: defect size, incision width, scar width, the Vancouver Scar Scale (VSS) and University of North Carolina 4P Scar Scale (UNC4P). Results A total of 25 pediatric patients (mean age, 9.88 years) were enrolled in the study. Following the treatment of SWTRD+CO2-AFL, scar widths were relatively narrow and the appearance of the incision scars was significantly improved. A significant reduction in the patient-reported UNC4P scores at 6 months (3, 1–4) was observed when compared with that at 2 months (0, 0–1) after surgery (p<0.001). A similar reduction in the VSS scar scale was also evident (6 months: 1, 0.75–2.5 vs 2 months: 6.5–8.5; p<0.001). Conclusion Combined SWTRD and CO2-AFL treatment effectively modulates the scar formation after the incision is healed and resulting in preventing scar widening, leading to the improvement of scar appearance, reduction in wound pain and pruritus and its overall prognosis.

Abstract
BACKGROUND The nose is located in the middle of the face; therefore, nasal scarring will bring a significant psychological impact on patients. Although there are many treatment methods for depressed scars, these methods have varying degrees of efficacy and all carry certain adverse effects. A better treatment method is urgent to be found. In this study, the effect of micro-plasma radiofrequency technology combined with subcision to treat nasal depressed scars is evaluated. METHODS 18 Chinese patients with nasal depressed scars participated in this study. All patients received one session of micro-plasma radiofrequency treatment first. 2 months later, subcision combined with micro-plasma radiofrequency technology was performed on them at 6-month intervals, and a total of 2 sessions of combined treatment were performed. Goodman and Baron Scale was used to evaluate nasal scars before treatment and 6 months after the final session. RESULTS All 18 patients in this study had Grade 4 nasal scars before treatment. 6 months after the end of treatment, 13 patients (72.2%) showed excellent or near total improvement, and 5 patients (27.8%) showed marked improvement. No adverse side effects were observed during treatment. Patient self-evaluation indicated that all patients were satisfied with the cosmetic outcomes. CONCLUSIONS In this study, we explored a new treatment method for nasal depressed scars. We used micro-plasma radiofrequency technology combined with subcision to treat nasal depressed scars and obtained relatively satisfactory results with no adverse effects.

Abstract
BACKGROUND Atrophic post-acne scarring is considered to be a therapeutic challenge. OBJECTIVES The aim was to compare the safety and efficacy of (A) FCL combined with intradermal injection of plasma gel, (B) FCL combined with topical application of plasma gel, and (C) FCL monotherapy in the treatment of atrophic post-acne scars. METHODS Thirty patients with facial atrophic post-acne scars were enrolled in this study and randomly assigned into one of three groups. All of them underwent four treatment sessions at 4-weeks intervals. They were assessed objectively by the quantitative global scarring grading system (GSGS). This system was applied at baseline, and after 1- and 6-month follow-up (FU). Subjective assessments were performed through the global esthetic improvement scale (GAIS) and level of patient satisfaction. The DLQI questionnaire was employed at the baseline and 6-month FU. RESULTS According to the quantitative GSGS scores, the reductions in group A (68.4%) and group B (63%) scores were comparable, and both were significantly higher than that in group C (41.2%) in all steps of evaluation. At 6-month FU, both groups A and B showed further significant improvement, while group C did not. Based on the GAIS and patients' satisfaction, there were no significant differences between all groups. The reductions in DLQI scores in groups A and B were comparable; however, both were significantly higher than group C (P < .001). CONCLUSIONS The combination of plasma gel and FCL resurfacing was noticeably outstanding in their efficacy and impact on the patients' quality of life.

Abstract
BACKGROUND Managing acne scars is a challenge and therapies are divided into nonsurgical and surgical. Highly Purified Technology Polynucleotides (PN-HPT) is a compound that contains a mixture of DNA polymers of different lengths. Numerous studies have shown that PN-HPT also serves as an energy source, thus influencing cellular growth and cell vitality. OBJECTIVES The authors aimed to assess the improvement in dermal quality and acne scars after PN-HPT vs placebo according to Antera 3D and the patient responses to the patient satisfaction questionnaire after a comparison of pretreatment and posttreatment photographs at 1 and 3 months. METHODS Included were women aged 30 to 50 years with grade 3 to 4 moderate-to-severe atrophic scars according to the Goodman classification; nonsmokers; and had not had active acne during the past 5 years. Ten patients (PN-HPT group) were treated with 4.0 mL of PN-HPT, and 10 patients (control) were treated with 4.0 mL of normal saline. All medical treatments were performed in a double-blinded manner; neither the injection doctor nor the patient knew if the PN-HPT or the placebo was being administered. RESULTS Twenty women who fit the inclusion criteria were enrolled in this study. Only patients in the PN-HPT group improved significantly at 1 and 3 months after treatment compared with baseline. CONCLUSIONS This prospective and randomized study showed that PN-HPT in monotherapy was safe and effective treatment for atrophic scar acne compared with placebo. Prospective and randomized studies will be necessary to investigate the clinical effectiveness in a larger cohort of patients and for a longer follow-up. LEVEL OF EVIDENCE: 2

Front Med (Lausanne) 2021; 8:662640. [PMID: 34095172 PMCID: PMC8175793 DOI: 10.3389/fmed.2021.662640] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Accepted: 04/29/2021] [Indexed: 11/20/2022] Open
Abstract
Background: Acne is a chronic disorder that affects almost 80% of adolescents and young adults, causing psychological and emotional distress. However, the current treatments for acne are either ineffective or have many side effects. This study was designed to confirm and objectively quantify the effect of a new non-drug combined therapy on acne. Methods: This study innovatively utilized ultrasound, which enhanced the absorption of aloe vera gel, and soft mask to make a purely physical method without any drugs. In both the treatment group and control group, the number of papules/pustules and the area of hyperpigmented lesions were counted, and a smart mirror intelligent face system was used before and after the combined therapy. Alterations in the skin functional index were recorded and analyzed statistically. Results: In the treatment group, the combined therapy significantly reduced the number of papules and the area of hyperpigmented lesions and improved skin roughness and local blood circulation. In the control group, there was no obvious improvement over 2 months. Conclusion: This study suggests that the new non-drug combined therapy significantly improved acne, which provided experimental evidence and treatment guidance for patients with mild to severe acne, especially patients with moderate acne. This new therapy may possibly be an appropriate method for patients who seek topical treatments with mild side effects and low antibiotic resistance rates.

Abstract
Erythema and scarring are among the most common complications of severe inflammatory acne. In this study, we aimed to share our experience with pro-yellow laser and document the efficacy and safety of this treatment in postacne erythema and scarring. The study included 40 patients, 24 (60%) females, and 16 (40%) males with a mean age of 29.5 ± 8.16 (min. 18 years, max. 57 years). The pro-yellow laser was applied to all patients as a single session with irradiation of 22 J/cm2 . Improvement in postacne erythema and scars were evaluated after the treatment. The study included 40 patients, 24 patients (60%) were females and 16 patients (40%) were males with the mean age of 29.5 ± 8.16 (ranged between 18 and 57 years old). A total of 21 patients (52.5%) had good improvement (51%-75% regression), 10 patients (25%) had excellent improvement (76%-100% regression), and a moderate improvement (26%-50%) was detected in 9 patients (22.5%). Also, there were mild improvement (1%-25%) in 20 patients (76.9%) and a moderate improvement (26%-50%) in 6 patients (23.1%). We found that pro-yellow laser is highly effective in the treatment of postacne erythema, while its effectiveness was mild to moderate in atrophic acne scars. Also, it has been observed that the pro-yellow laser system can be used safely immediately after cessation of systemic isotretinoin treatment.

Abstract
Fractional CO2 laser is a good option for treating acne scars. However, the clinical efficacy of this treatment modality requires further evidence. To perform a meta-analysis to assess clinical improvements in acne scars with fractional CO2 laser and non-CO2 laser therapies. Databases (PubMed, Embase, Cochrane Library) were searched using the search strategy to identify eligible studies. All statistical analyses were performed using the Review Manager 5.0, and a meta-analysis was conducted to assess the effects of fractional CO2 laser used as a treatment for acne scars. Eight studies were included for further analysis. There was no significant difference between fractional CO2 laser and non-CO2 laser therapies in terms of clinical improvement, observer assessment (P = .19), patient assessment (P = .91), and incidence of post-inflammatory hyperpigmentation (P = .69). The subgroup analyses showed that the duration of follow-up had little effect on the evaluation of treatment effect. The efficacy of fractional CO2 laser therapy in acne scars appeared to be equal to that of non-CO2 laser therapies. More well designed randomized controlled trials and more credible and standard evaluation criteria are needed, and the efficiency of combination therapy requires further analysis.

Dermatol Ther 2020; 33:e14488. [PMID: 33131170 DOI: 10.1111/dth.14488] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Revised: 10/18/2020] [Accepted: 10/26/2020] [Indexed: 12/13/2022]
Abstract
Lyophilized-growth factors (L-GFs), is a new platelet rich plasma (PRP) preparation that is standardized in growth factors concentrations. The aim of this study was to compare the therapeutic efficacy of ablative fractional CO2 laser in combination with L-GFs vs PRP in post-acne scars. This study was conducted on 45 patients presented with facial post-acne scars. Each patient received three sessions of fractional CO2 laser on both sides of the face followed by topical application of L-GFs on one side and conventional PRP on the other side. Assessment was done before and after treatment semiquantitatively by Echella d'Èvaluation Clinique des Cicatrices d'Acné (ECCA) score and qualitatively by Goodman and Baron's qualitative scar (GBQS) scale, in addition to dermoscopic evaluation. The current study reported significant clinical improvement of post-acne scars on both sides of the face evidenced by significant reduction of both ECCA score and GBQS scale with minimal side effects. The degree of clinical improvement and patients' satisfaction were significantly higher with shorter downtime in response to fractional CO2 laser combined with L-GFs rather than its combination with PRP. In conclusion, laser assisted delivery of L-GFs via fractional CO2 laser could be considered a novel successful therapeutic modality for post-acne scars.

Abstract
We investigated the effectiveness of fractional carbon dioxide laser (FCO2 ) vs fractional radiofrequency (FRF) and FCO2 vs FRF plus FCO2 combination in the treatment of acne scars. Twenty-seven patients were included. Scar severity was scored with "Echelle d'évaluation clinique des cicatrices d'acné" (ECCA) by a dermatologist blinded to treatment. FCO2 and FRF were administered to the right and left halves of the patients' faces, respectively, at the first three visits, once a month. At the fourth visit, FCO2 was administered to both sides. Last evaluation was performed 6 months after the last treatment. Mean ECCA scores for both face halves decreased gradually at each visit compared with Visit-1; however, the effect size of decrease was higher in the right half of the face and in terms of gender differences was higher in women for both sides that the difference was more pronounced for the FRF side. There was no statistically significant change in the mean VAS patient satisfaction scores in the following visits compared with Visit-2 on both halves (P > .05). Side effects were similar; but lasted longer in the FCO2 side. Both FCO2 and FRF are effective treatment methods in the treatment of atrophic acne scars. Combining FCO2 to FRF improves patient satisfaction. FRF may achieve better results in women compared with men. To our knowledge the study is unique prospective, controlled clinical study comparing the efficacy of FCO2 and FRF plus FCO2 combination treatments.

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 Acne scars are the most common sequelae of the severe inflammatory process of acne, and its managing is a challenge. Objective of this study was to assess safety and effectiveness of calcium hydroxylapatite monotherapy and its association with high-intensity microfocused ultrasound for treating moderate-to-severe atrophic acne scars. METHODS Women with moderate-to-severe atrophic scars of the face were enrolled on the study. Assessments were made by digital macrophotographs, Vectra H2, and Antera 3D. RESULTS From October to December 2019, twenty women which fitted the inclusion criteria signed a consent form and received 3.0 mL of calcium hydroxylapatite and after 4 weeks, 400 lines of HIFU. No major side effects were reported during the study, and all patients completed the follow-up after 6 months. At 1 month, patients treated with calcium hydroxylapatite (group 1) improved wrinkles and skin texture compared to placebo (group 2). At 3 and 6 months, all patients improved acne scars. CONCLUSION Our study showed that that both calcium hydroxylapatite and HIFU in monotherapy were safe and effective treatments for atrophic scar acne. Calcium hydroxylapatite was clinically effective when compared with placebo, though the combination of calcium hydroxylapatite and HIFU did not enhance the clinical efficacy compared to monotherapy.

Abstract
Acne scars are the ultimate outcome of acne vulgaris, a prevalent skin disorder affecting the pilo-sebaceous unit. Laser resurfacing has been demonstrated to be an efficient therapy option for acne scars. Hence, we adopted this concept and conducted a study to evaluate the safety and efficacy of low-energy double-pass 1450-nm diode laser on acne scars. This study was conducted on 48 patients with acne scars, treated at 4-week interval with low-energy double-pass 1450-nm diode laser. Patients were evaluated clinically and with photographs, at day 0, first month and third month post the final treatment and during follow-up visit. Five treatment sessions were completed by all patients. Approximately, 79.2% of patients showed around 30% improvement. At the end of third month follow-up, 92.9% of the patients demonstrated >30% improvement. Vesicle formation was observed in two cases, with no post-inflammatory hyperpigmentation and transient hyperpigmentation was observed in one case, which vanished within 2 months. Our study showed that 1450-nm diode laser treatment was efficient and well endured in facial acne scars when used with double-pass at low-energy.
