Liu F, Zhou Q, Tao M, Shu L, Cao Y. Efficacy and safety of CO 2 fractional laser versus Er:YAG fractional laser in the treatment of atrophic acne scar: A meta-analysis and systematic review. J Cosmet Dermatol 2024; 23:2768-2778. [PMID: 38733085 DOI: 10.1111/jocd.16348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Revised: 04/01/2024] [Accepted: 04/16/2024] [Indexed: 05/13/2024]
Abstract
BACKGROUND To date, a consensus on the relative efficacy and safety of CO2 fractional laser versus erbium-doped yttrium aluminum garnet (Er:YAG) fractional laser treatments for atrophic acne scars has not been reached. This meta-analysis aims to systematically assess and compare their effectiveness and safety in clinical practice. METHODS For this meta-analysis, we conducted comprehensive searches in Pubmed, Embase, and Cochrane databases, covering publications from their inception up to August 2023. Our focus was on studies comparing fractional CO2 laser with Er:YAG fractional laser treatments for atrophic acne scars. We excluded duplicate publications, research lacking full-text access, incomplete data, or cases where data extraction was not feasible. Additionally, animal experiments, reviews, and systematic reviews were not considered. Data analysis was performed using STATA 15.1. RESULTS Eight studies (seven randomized controlled trials (RCTs) and a retrospective study) were included in this meta-analysis. The sample size ranged from 28 to 106 with a total of 418 patients, including 210 in the CO2 fractional group and 208 in Er:YAG fractional group. The pooled results showed that the effective rate of CO2 fractional laser in treating atrophic acne scar was significantly higher than that of Er:YAG fractional laser (OR = 1.81, 95% CI: 1.08-3.01) and the downtime of CO2 fractional laser in treating atrophic acne scar was significantly shorter than that of Er:YAG fractional laser (Weighted Mean Difference (WMD) = -2.11, 95% CI: -3.11 to -1.10). In addition, VAS of CO2 fractional laser in treating atrophic acne scar was significantly higher than that of Er:YAG fractional laser (WMD = 1.77, 95% CI: 1.32-2.21) and the duration of erythema of CO2 fractional laser in treating atrophic acne scar was significantly longer than that of Er:YAG fractional laser (WMD = 1.85, 95% CI: 1.63-2.07). However, there was no significant difference in the duration of pain and incidence of PIHbetween CO2 fractional laser and of Er:YAG fractional laser. CONCLUSION When it comes to treating atrophic acne scars, CO2 fractional laser demonstrates superior efficacy and leads to shorter downtime. However, it is important to note that CO2 fractional laser treatments tend to result in higher pain intensity and may carry a higher risk of post-treatment pigmentation compared to Er:YAG fractional laser procedures.

Abstract
BACKGROUND Acne vulgaris poses significant physical and psychological challenges worldwide. Data of adapalene 0.3%/benzoyl peroxide 2.5% gel (A0.3/BPO2.5) for acne treatment in Asian patients is limited. METHODS In this randomized double-blind clinical trial, 49 Korean patients with moderate-to-severe acne and scars were assigned to the A0.3/BPO2.5 (N.=37) or vehicle (N.=12) group. Acne and acne scar severity scores were assessed at baseline and 4, 8, 12, and 24 weeks. The primary outcomes were treatment success rate (reduction of ≥2 Investigator's Global Assessment grade and reaching a grade of 0 or 1) and proportional acne lesion and scar count reduction against the baseline. To assess histological changes, 2-mm punch biopsies were performed at baseline and week 24 on the respective inflammatory lesions or scars. RESULTS At week 24, the A0.3/BPO2.5 group had a significantly higher treatment success rate than the vehicle group. The total acne count, inflammatory lesion count, and non-inflammatory lesion count percentages (against baselines) with A0.3/BPO2.5 and the vehicle were 12.1% vs. 96.7%, 8.0% vs. 101.2%, and 13.3% vs. 98.9%, respectively (all P<0.001). Scar count percentages (against baselines) with A0.3/BPO2.5 and the vehicle were 27.3% and 96.5%, respectively (P<0.001). Significant elevations in collagen 1 and 3, elastin, CK15, and p63 levels, with increases of 172.7%, 230.6%, 176.5%, 286.2%, and 105.9%, respectively, in comparison to baseline (all P<0.05). No major adverse events leading to discontinuation were observed. CONCLUSIONS A0.3/BPO2.5 was an effective and safe treatment for acne and acne scars in Asian patients supported by robust histopathological and immunohistochemical evidence.

Fractional Radiofrequency and Oral Isotretinoin-A Prospective Randomized Controlled Split-Face Trial Comparing Concurrent Versus Delayed Fractional Radiofrequency Treatment for Acne Scars. Lasers Surg Med 2024; 56:574-580. [PMID: 38890778 DOI: 10.1002/lsm.23811] [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: 02/28/2024] [Revised: 04/19/2024] [Accepted: 05/19/2024] [Indexed: 06/20/2024]
Abstract
BACKGROUND Therapeutic dogma has been to treat acne scars no less than 6 months after isotretinoin (ITN) cessation. OBJECTIVE To evaluate the safety and efficacy of fractional radiofrequency (FRF) in patients treated concurrently with ITN. METHODS We conducted a prospective randomized control 3-arm comparative trial to evaluate the treatment of acne scars. Patients received one of three treatment options: (A) ITN and FRF concurrent treatment, (B) ITN monotherapy, and (C) FRF 6 months post-ITN treatment. Patients in the FRF cohorts received three monthly sessions. Patients were followed for adverse effects up to 6-9 months post-FRF treatment. Final cosmesis was scored by three independent dermatologists using two scales: the Echelle d'Evaluation Clinique des Cicatrices d'Acne (ECCA) and an internal 5-point investigator's scale, indicating the percentage of improvement. Subjective analyses by patients were also assessed. RESULTS Objective and subjective analyses revealed improvement in the ITN-FRF cohort, which was superior to the delayed FRF cohort and the ITN monotherapy cohort. Specifically, the concurrently treated cohort (ITN-FRF) had a significant reduction in acne scar volume from baseline mean (151.1 ± 44.7 to 97.0 ± 31.2, p < 0.005), outperforming both the delayed FRF and monotherapy ITN treatment cohorts, respectively (155.4 ± 37.8 to 122.0 ± 46.2, 144.6 ± 82.8 to 132.4 ± 62.7). Additionally, the concurrently treated cohort demonstrated improved ECCA scores (36.8 ± 15.5), significantly better than the ITN monotherapy cohort (101.5 ± 20.1, p < 0.01). LIMITATIONS Limited patient sample size: 38 patients completed the study; mostly Fitzpatrick Type II-III skin; photographic assessments utilized. CONCLUSION Per our prospective trial, concurrent treatment of ITN-FRF is superior to delayed FRF treatment 6 months post-ITN cessation.

Effect of magnetic microbeads on sustained and targeted delivery of transforming growth factor-beta-1 for rotator cuff healing in a rat rotator cuff repair model. Sci Rep 2024; 14:17632. [PMID: 39085278 PMCID: PMC11292015 DOI: 10.1038/s41598-024-67572-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Accepted: 07/12/2024] [Indexed: 08/02/2024] Open
Abstract
Structural failure is a well-established complication of rotator cuff repair procedures. To evaluate the effect of magnetic microbeads, designed for precise drug delivery via magnetic force, on sustained transforming growth factor-beta-1 (TGF-β1) release and rotator cuff healing in a rat rotator cuff repair model. TGF-β1 laden microbeads were prepared, and baseline in vitro experiments included the magnetization of the microbeads and TGF-β1 release tests. In an in vivo experiment using a rat rotator cuff repair model on both shoulders, 72 rats were randomly assigned to three groups (24 per group): group A, conventional repair; group B, repair with and simple TGF-β1 injection; and group C, repair with magnet insertion into the humeral head and TGF-β1 laden microbead injection. Delivery of TGF-β1 was evaluated at 1 and 7 days after the intervention using PCR, Western blot, and immunohistochemistry. At 6 weeks post-intervention, rotator cuff healing was assessed using biomechanical and histological analysis. The in vitro experiments confirmed the magnetization property of the microbeads and sustained delivery of TGF-β1 for up to 10 days. No difference in the TGF-β1 expression was found at day 1 in vivo. However, at day 7, group C exhibited a significantly elevated expression of TGF-β1 in both PCR and Western blot analyses compared to groups A and B (all P < 0.05). Immunohistochemical analysis revealed a higher expression of TGF-β1 at the repair site in group C on day 7. At 6 weeks, biomechanical analysis demonstrated a significantly higher ultimate failure load in group C than in groups A and B (P < 0.05) and greater stiffness than in group A (P = 0.045). In addition, histological analysis showed denser and more regular collagen fibers with complete continuity to the bone in group C than in groups A and B, a statistically significant difference according to the semi-quantitative scoring system (all P < 0.05). The use of the TGF-β1 laden magnetic microbeads demonstrated sustained delivery of TGF-β1 to the repair site, improving rotator cuff healing.

Decellularized Wharton's Jelly and Amniotic Membrane Demonstrate Potential Therapeutic Implants in Tracheal Defects in Rabbits. Life (Basel) 2024; 14:782. [PMID: 38929764 PMCID: PMC11204711 DOI: 10.3390/life14060782] [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: 05/22/2024] [Revised: 06/12/2024] [Accepted: 06/16/2024] [Indexed: 06/28/2024] Open
Abstract
BACKGROUND Tracheal grafts have been investigated for over a century, aiming to replace various lesions. However, tracheal reconstruction surgery remains a challenge, primarily due to anatomical considerations, intraoperative airway management, the technical complexity of reconstruction, and the potential postoperative morbidity and mortality. Due to research development, the amniotic membrane (AM) and Wharton's Jelly (WJ) arise as alternatives within the new set of therapeutic alternatives. These structures hold significant therapeutic potential for tracheal defects. This study analyzed the capacity of tracheal tissue regeneration after 60 days of decellularized WJ and AM implantation in rabbits submitted to conventional tracheostomy. METHODS An in vivo experimental study was carried out using thirty rabbits separated into three groups (Control, AM, and WJ) (n = 10). The analyses were performed 60 days after surgery through immunohistochemistry. RESULTS Different immunomarkers related to scar regeneration, such as aggrecan, TGF-β1, and α-SMA, were analyzed. However, they highlighted no significant difference between the groups. Collagen type I, III, and Aggrecan also showed no significant difference between the groups. CONCLUSIONS Both scaffolds appeared to be excellent frameworks for tissue engineering, presenting biocompatibility and a desirable microenvironment for cell survival; however, they did not display histopathological benefits in trachea tissue regeneration.

Abstract
Acne scarring is common and can occur even with effective acne management. In addition, patients with acne scarring suffer from significant psychosocial morbidity, including depression and suicidality. Despite the availability and advancement of therapeutic modalities, treatment for acne scarring is not always optimized and often overlooked in patients with acne encounters. Using acne scarring assessment tools and identifying specific acne scar subtypes allows for a tailored therapeutic approach. Part I of this continuing medical education series covers the pathophysiology and morphology of textural and pigmented acne scars, scarring assessment tools, and medical treatment options. The principles reviewed will aid in approaching and initiating acne scar treatment in the outpatient setting.

Abstract
BACKGROUND Atrophic acne scarring is a common sequela of inflammatory acne, causing significant problems for affected patients. Although prolonged inflammation and subsequent aberrant tissue regeneration are considered the underlying pathogenesis, the role of epidermal stem cells, which are crucial to the regeneration of pilosebaceous units, remains unknown. OBJECTIVES To examine the changes occurring in epidermal stem cells in atrophic acne scars. METHODS Changes in collagen, elastic fibre and human leukocyte antigen (HLA)-DR expression were analysed in normal skin and inflammatory acne lesions at days 1, 3 and 7 after development. The expression of epidermal stem cell markers and proliferation markers was compared between normal skin and mature atrophic acne scar tissue. RESULTS In acne lesions, inflammation had invaded into pilosebaceous units over time. Their normal structure had been destructed and replaced with a reduced amount of collagen and elastic fibre. Expression of stem cell markers including CD34, p63, leucine-rich repeat-containing G protein-coupled receptor (LGR)6 and LGR5, which are expressed in the interfollicular epidermis, isthmus and bulge of hair follicles, significantly decreased in atrophic acne scar tissue compared to normal skin. Epidermal proliferation was significantly reduced in scar tissue. CONCLUSIONS These findings suggest that as inflammatory acne lesions progress, inflammation gradually infiltrates the pilosebaceous unit and affects the resident stem cells. This disruption impedes the normal regeneration of the interfollicular epidermis and adnexal structures, resulting in atrophic acne scars.

Abstract
Wounds and the subsequent formation of scars constitute a unified and complex phased process. Effective treatment is crucial; however, the diverse therapeutic approaches for different wounds and scars, as well as varying treatment needs at different stages, present significant challenges in selecting appropriate interventions. Microneedle patch (MNP), as a novel minimally invasive transdermal drug delivery system, has the potential for integrated and programmed treatment of various diseases and has shown promising applications in different types of wounds and scars. In this comprehensive review, the latest applications and biotechnological innovations of MNPs in these fields are thoroughly explored, summarizing their powerful abilities to accelerate healing, inhibit scar formation, and manage related symptoms. Moreover, potential applications in various scenarios are discussed. Additionally, the side effects, manufacturing processes, and material selection to explore the clinical translational potential are investigated. This groundwork can provide a theoretical basis and serve as a catalyst for future innovations in the pursuit of favorable therapeutic options for skin tissue regeneration.

Abstract
BACKGROUND Acne, a chronic inflammatory disease impacting the pilosebaceous unit, is influenced significantly by inflammation and oxidative stress, and is commonly associated with obesity. Similarly, obesity is also associated with increased inflammation and oxidation. The role of diet in acne remains inconclusive, but the very low-calorie ketogenic diet (VLCKD), known for weight loss and generating anti-inflammatory ketone bodies, presents promising potential. Despite this, the effects of VLCKD on acne remain underexplored. This study aimed to investigate the efficacy of a 45-day active phase of VLCKD in reducing the clinical severity of acne in young women with treatment-naïve moderate acne and grade I obesity. METHODS Thirty-one women with treatment-naïve moderate acne, grade I obesity (BMI 30.03-34.65 kg/m2), aged 18-30 years, meeting inclusion/exclusion criteria, and consenting to adhere to VLCKD were recruited. Baseline and post-intervention assessments included anthropometric measurements, body composition, phase angle (PhA), trimethylamine N-oxide (TMAO) levels, and reactive oxygen metabolite derivatives (dROMs) as markers of inflammation, dysbiosis, and oxidative stress, respectively. A comprehensive dermatological examination, incorporating the Global Acne Grading System (GAGS) and the Dermatology Life Quality Index (DLQI), was conducted for all women. RESULTS VLCKD resulted in general improvements in anthropometric and body composition parameters. Significantly, there were significant reductions in both the GAGS score (Δ%: - 31.46 ± 9.53, p < 0.001) and the DLQI score (Δ%: - 45.44 ± 24.02, p < 0.001) after the intervention. These improvements coincided with significant decreases in TMAO (p < 0.001) and dROMs (p < 0.001) levels and a significant increase in PhA (Δ%: + 8.60 ± 7.40, p < 0.001). Changes in the GAGS score positively correlated with changes in dROMs (p < 0.001) and negatively with PhA (p < 0.001) even after adjusting for Δ% FM. Changes in the DLQI score positively correlated with changes in dROMs (p < 0.001) and negatively with PhA (p < 0.001) even after adjustment for Δ% FM. CONCLUSION Given the side effects of drugs used for acne, there is an increasing need for safe, tolerable, and low-cost treatments that can be used for acne disease. The 45-day active phase of VLCKD demonstrated notable improvements in acne severity, and these improvements seemed to be attributable to the known antioxidant and anti-inflammatory effects of VLCKD.

Abstract
BACKGROUND Differences in clinical efficacy based on the fluence of fractional picosecond laser treatment for acne scars are unknown. OBJECTIVE To compare the efficacy and safety of low-fluence versus high-fluence fractional picosecond Nd:YAG 1064-nm laser treatment in acne scar patients. METHODS In this 12-week, investigator-blinded, randomized, split-face study, 25 patients with moderate-to-severe acne scars received three sessions of high-fluence laser treatment (1.0 J/cm2 ) on one side of their face and low-fluence (0.3 J/cm2 ) on the other side every 4 weeks. Patients were assessed using acne scar counts, the scar global assessment (SGA), and the ECCA scar grading scale every 4 weeks. The histological analysis compared the acne scars obtained before and 4 weeks after treatment. RESULTS At their last visit, 88.00% and 92.00% of the subjects achieved >30% reduction in scar counts on the low- and high-fluence sides, respectively, without a significant difference between the two sides. On both sides, the scar counts, SGA, and ECCA score significantly improved 4 weeks after the last treatment. Although the high-fluence side showed a greater reduction in scar counts (-66.73%) than the low-fluence side (-62.13%), the two sides had no significant difference in the grading scores. The high-fluence side showed significantly more severe pain and higher side-effect scores immediately and 4 weeks after treatment. Histological analysis revealed a significantly increased collagen, elastin, and vimentin expression after treatment on the low-fluence side. CONCLUSIONS The low-fluence setting demonstrated comparable efficacy and superior safety in treating acne scars compared with the high-fluence setting.

Fractional ablative CO 2 laser and oral isotretinoin-A prospective randomized controlled split-face trial comparing concurrent versus delayed laser treatment for acne scars. Lasers Surg Med 2024; 56:54-61. [PMID: 37555247 DOI: 10.1002/lsm.23713] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 07/17/2023] [Accepted: 07/17/2023] [Indexed: 08/10/2023]
Abstract
BACKGROUND Therapeutic dogma has been to treat acne scars with ablative fractional laser no less than 6 months after isotretinoin (ITN) cessation. OBJECTIVE To evaluate the safety and efficacy of fractional ablative CO2 laser (FACL) in patients treated concurrently with ITN. METHODS We conducted a prospective split-face randomized control trial in patients treated with FACL concurrently with ITN versus patients treated with FACL 6 months post-ITN treatment. Patients received 3 monthly sessions of FACL with concurrent ITN treatment on half of the face; the other side of the face received the same FACL treatment regimen 6 months post-ITN cessation. Patients were followed for adverse effects up to 6 months post-FACL treatment. Final cosmesis was scored using the Quantitative Global Acne Scarring Grading System (GASGS) by three independent dermatologists. RESULTS The GASGS of the concurrent ITN-FACL treated side of the face was significantly lower than the side treated with delayed laser therapy (4.7 ± 2.5 vs. 7.7 ± 2.9, respectively, p < 0.001). LIMITATIONS The laser's settings were standardized, and not adjusted per patient skin type. CONCLUSION Per our prospective trial, concurrent treatment of FACL -ITN is superior to delayed FACL treatment 6 months post-ITN cessation. Fractional ablative laser treatment is effective in improving acne scars, which persist despite isotretinoin therapy.

Abstract
BACKGROUND Atrophic acne scarring is a common problem. If left untreated, its implications can impair the quality of life. Various treatments, with differing degrees of success, are used to alleviate atrophic scars. OBJECTIVE To assess the efficacy of nanofat versus platelet-rich plasma (PRP) as an adjuvant therapy to fractional CO 2 laser (FCL) for atrophic acne scars. METHODS This study included 35 patients with atrophic acne scars who received 3 sessions of FCL at 1-month intervals on both sides of the face, followed by intradermal PRP injection on the left side. A single session of nanofat was injected into the right side of the face 2 weeks before the laser sessions. The evaluation was conducted 3 months after the final treatment session. RESULTS After treatment, the right side of the face showed a significant reduction in Goodman scores and the indentation index of the Antera camera. The left side showed a significant difference in Goodman scores, yet the Antera camera showed a nonsignificant improvement. Nonetheless, the difference between the 2 sides was statistically insignificant. CONCLUSION Atrophic acne scars improved with both modalities. As a result, cotreatment with these techniques may synergistically affect atrophic acne scars in efficacy and safety.

Abstract
Emodin, a natural anthraquinone derivative, possesses anti-proliferative and anti-inflammatory properties in skin diseases. However, little information is available on the efficacy of emodin in treating acne vulgaris (acne). This study aims to investigate the protective effects and potential mechanisms of emodin as an anti-acne agent. In vitro, SZ95 sebocytes was chose to establish an acneigenic cellular model. We found that emodin effectively inhibited proliferation, induced cell cycle arrest and apoptosis of SZ95 sebocytes in a dose-dependent manner. To evaluate the lipid-lowering potential of emodin, we examined the levels of lipid contents and lipogenic transcription factors, and found that both lipid production and protein expression of PPARγ, LXR α/β, and SREBP-1 were decreased after treatment with emodin. Furthermore, our results revealed that emodin inhibited sebaceous lipogenesis induced by insulin-like growth factor 1 (IGF-1), which was accompanied by a potent inhibition of the phosphoinositide-3-kinase (PI3K)/Akt/forkhead box protein O1 (FoxO1) pathway. In detail, emodin augmented the inhibitory effect of isotretinoin and PI3K inhibitor LY294002, while attenuating the activation of IGF-1 on PI3K/Akt/FoxO1 pathway. In addition, emodin could decrease the secretion of pro-inflammatory cytokines IL-6 and IL-8, and suppress the expression of NLRP3, capase-1, IL-1β, and IL-18 in SZ95 sebocytes exposed to Cutibacterium acnes. Overall, our study provides preliminary evidence supporting the anti-growth, anti-lipogenic and anti-inflammatory properties of emodin, indicating the potential therapeutic application of emodin for acne treatment.

Abstract
OBJECTIVE This study aimed to observe the fluorescence characteristics of acne inflammatory skin lesions in 5-aminolevulinic acid-based photodynamic diagnosis (ALA-PDD), and discuss the viability of using ALA-PDD to evaluate acne inflammatory skin lesions and explore the advantages of predicting subclinical skin lesions. METHODS The OBSERV facial skin detector collected photographs of 20 patients before and after optical intra-tissue fiber irradiation photodynamic therapy (OFI-ALA-PDT) in both ALA-PDD and white light patterns. The patients were treated once a week for four consecutive weeks in order to analyze the correlation between the two patterns in recognizing inflammatory skin lesions. RESULTS Before and after treatment, there was no significant difference between the two patterns for recognizing acne inflammatory skin lesions (p > 0.05). Both patterns demonstrated a strong correlation (r > 0.90) for the recognition of various types of inflammatory skin lesions at different treatment stages. CONCLUSION ALA-PDD is a feasible method for evaluating acne inflammatory lesions, guiding treatment and judging efficacy. It has advantages in predicting subclinical skin lesions and deserves further study.

Abstract
OBJECTIVES Patients with acne usually develops acne scars subsequently, early intervention of scars is crucial in acne management. 1927nm fractional thulium fiber laser (TFL) is effective in scars improvement and chemical peels with 30% supramolecular salicylic acid (SSA) can be applied for the treatment of acne. The purpose of this study is to evaluate and compare the efficacy and safety of TFL monotherapy versus the concomitant application of TFL and 30% SSA on acne and acne scars. MATERIALS AND METHODS Thirty-three patients with acne and acne scars were enrolled, and two sides of the face were randomly divided to receive either TFL and SSA chemical peeling or TFL. Four sessions of TFL treatments were applied with 4-week intervals for both sides, SSA combined treatment side received eight SSA chemical peels with 2-week intervals additionally. GAGS, ECCA score, the number of acne lesions, melanin index (MI) and erythema index (EI), transepidermal water loss (TEWL), and side effects were recorded at Weeks 0, 4, 8, 12, and 18. Satisfaction of patients was recorded on both sides at the end of the study. RESULTS Thirty patients completed the study. Both control group (TFL monotherapy) and SSA group (TFL combined with SSA chemical peeling) significantly improved GAGS and ECCA score. SSA group showed higher efficacy in terms of GAGS and ECCA score, acne lesion count, TEWL, MI, EI, and satisfaction than control group. All the side effects were temporary and tolerable, no adverse effects were observed. CONCLUSIONS Both TFL and the TFL combined with 30% SSA chemical peeling are safe and effective for the treatment and prevention of acne and acne scars, though the combined group has higher efficacy.

Efficacy and safety of 1565-nm nonablative fractional laser combined with mucopolysaccharide polysulfate cream for erythematous acne scars. J Cosmet Dermatol 2023; 22:3008-3016. [PMID: 37464984 DOI: 10.1111/jocd.15935] [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: 07/29/2022] [Revised: 06/12/2023] [Accepted: 07/09/2023] [Indexed: 07/20/2023]
Abstract
PURPOSE To evaluate the efficacy and safety of 1565-nm nonablative fractional laser (NAFL) combined with mucopolysaccharide polysulfate (MPS) cream in the treatment of erythematous acne scars. METHODS A total of 28 subjects with erythematous acne scars from June 2021 to April 2022 were enrolled. One side of each subject's face was randomly assigned to be treated with 1565-nm NAFL (at 2 sessions with four-week intervals) combined with MPS cream (twice daily) for 8 weeks, and the other side with 1565-nm NAFL combined with placebo cream. CBS® images and parameters, dermoscopic images and the quantitative data processed by ImageJ software, and quantitative global scarring grading system (GSS) score were obtained at baseline and after treatment. Subjects' satisfaction assessment was performed after treatment. Adverse events were recorded during treatment. RESULTS In CBS® parameters, the red area, red area concentration, and smoothness were improved more significantly on the 1565-nm NAFL combined with MPS cream side than on the 1565-nm NAFL combined with placebo cream side after treatment (p = 0.015, p = 0.013, and p = 0.021). For dermoscopy, both scar area and scar redness achieved a significantly greater percentage of improvement on the side of 1565-nm NAFL combined with MPS cream than the side of 1565-nm NAFL combined with placebo cream after treatment (p = 0.005 and p = 0.041). The reduction of quantitative GSS score and Subjects' satisfaction assessment were similarly superior on the 1565-nm NAFL combined with MPS cream side. Temporary erythema was experienced by all subjects after each 1565-nm NAFL treatment. No subject reported intolerance or allergy to the cream during follow-up. CONCLUSIONS The combined application of 1565-nm NAFL and MPS cream could be an effective and safe treatment for erythematous acne scars. ImageJ software enables quantitative evaluation of dermoscopic images of acne scars.

Abstract
BACKGROUND Acne scar is a persistent complication of acne vulgaris. However, the prevalence and risk factors are still unclear. This study aimed to assess the global prevalence and risk factors of acne scars in patients with acne. MATERIALS AND METHODS A systematic search of published studies in three databases was performed and the meta-analyses were conducted. RESULTS Finally, we included 37 studies involving 24 649 acne patients. And, the pooled prevalence of acne scars in these patients was 47% (95% confidence interval [CI]: 38-56%). Besides, the differences in prevalence were observed based on the subgroup analysis for age, gender, acne severity, source of patients, and so on. Subsequently, we quantified the relationship of three risk factors with acne scars: male gender (odds ratio [OR]: 1.58, 95% CI: 1.19-2.09), positive family history of acne (OR: 2.73, 95% CI: 1.26-5.91), and acne severity (OR for moderate acne: 2.34, 95% CI: 1.54-3.57; OR for severe acne: 5.51, 95% CI: 2.45-12.41). CONCLUSION Herein, we found that 47% of acne patients suffered from acne scars and identified three risk factors: male gender, positive family history of acne, and acne severity. In order to reduce acne scarring, attention and effective therapy early in the course of acne is important.

Abstract
Traumatic scar is a disease that affected approximately tens of millions of patients worldwide. According to the histological and morphological properties of scars, the traumatic scar typically includes superficial scar, atrophic scar, hypertrophic scar, and keloid. Its formation is a natural consequence of wound healing, regardless of whether the wound was caused by trauma or surgery. However, the production of scars has considerable impacts on the physical and mental health of patients, even causing substantial aesthetic and functional impairments. Prevention or early treatment of scars is the most suitable therapeutic method, including surgical and non-surgical procedures; nevertheless, the benefits of non-operative therapies for scars are quite limited, and surgical treatments are always hard to achieve satisfying outcomes. Through the application of innovative technologies such as lasers, intense pulsed light, and radiofrequency, significant progress has been made in the treatment of traumatic scars. This review highlights the current advancements of photoelectric therapy for the prevention and treatment of various traumatic scars, which may throw light on innovative therapeutic options for scar therapies.

Abstract
Acne is a chronic inflammatory disease of the pilosebaceous unit resulting from androgen-induced increased sebum production, altered keratinization, inflammation, and bacterial colonization of the hair follicles of the face, neck, chest and back by Propionibacterium acnes. Overall, inflammation and immune responses are strongly implicated in the pathogenesis of acne. Although early colonization with Propionibacterium acnes and family history may play an important role in the disease, it remains unclear exactly what triggers acne and how treatment affects disease progression. The influence of diet on acne disease is a growing research topic, yet few studies have examined the effects of diet on the development and clinical severity of acne disease, and the results have often been contradictory. Interestingly, very low-calorie ketogenic diet (VLCKD) has been associated with both significant reductions in body weight and inflammatory status through the production of ketone bodies and thus it has been expected to reduce the exacerbation of clinical manifestations or even block the trigger of acne disease. Given the paucity of studies regarding the implementation of VLCKD in the management of acne, this review aims to provide evidence from the available scientific literature to support the speculative use of VLCKD in the treatment of acne.

Abstract
Scars caused by skin injuries after burns, wounds, abrasions and operations have serious physical and psychological effects on patients. In recent years, the research of scar free wound repair has been greatly expanded. However, understanding the complex mechanisms of wound healing, in which various cells, cytokines and mechanical force interact, is critical to developing a treatment that can achieve scarless wound healing. Therefore, this paper reviews the types of wounds, the mechanism of scar formation in the healing process, and the current research progress on the dual consideration of wound healing and scar prevention, and some strategies for the treatment of scar free wound repair.

Abstract
Background Characterized by an inflammatory pathogenesis, acne is the most common skin disorder worldwide. Altered sebum production, abnormal proliferation of keratinocytes, and microbiota dysbiosis represented by disbalance in Cutibacterium acnes population structure, have a synergic effect on inflammation of acne-compromised skin. Although the role of C. acnes as a single factor in acne development is still under debate, it is known that skin and skin-resident immune cells recognize this bacterium and produce inflammatory markers as a result. Control of the inflammatory response is frequently the target for acne treatment, using diverse chemical or physical agents including antibiotics. However, some of these treatments have side effects that compromise patient adherence and drug safety and in the case of antibiotics, it has been reported C. acnes resistance to these molecules. Phage therapy is an alternative to treat antibiotic-resistant bacterial strains and have been recently proposed as an immunomodulatory therapy. Here, we explore this perspective about phage therapy for acne, considering the potential immunomodulatory role of phages. Methodology Literature review was performed using four different databases (Europe PubMed Central-ePMC, Google Scholar, PubMed, and ScienceDirect). Articles were ordered and selected according to their year of publication, number of citations, and quartile of the publishing journal. Results The use of lytic bacteriophages to control bacterial infections has proven its promising results, and anti-inflammatory effects have been found for some bacteriophages and phage therapy. These effects can be related to bacterial elimination or direct interaction with immune cells that result in the regulation of pro-inflammatory cytokines. Studies on C. acnes bacteriophages have investigated their lytic activity, genomic structure, and stability on different matrices. However, studies exploring the potential of immunomodulation of these bacteriophages are still scarce. Conclusions C. acnes bacteriophages, as well as other phages, may have direct immunomodulatory effects that are yet to be fully elucidated. To our knowledge, to the date that this review was written, there are only two studies that investigate anti-inflammatory properties for C. acnes bacteriophages. In those studies, it has been evidenced reduction of pro-inflammatory response to C. acnes inoculation in mice after bacteriophage application. Nevertheless, these studies were conducted in mice, and the interaction with the immune response was not described. Phage therapy to treat acne can be a suitable therapeutic alternative to C. acnes control, which in turn can aid to restore the skin's balance of microbiota. By controlling C. acnes colonization, C. acnes bacteriophages can reduce inflammatory reactions triggered by this bacterium.

Abstract
BACKGROUND Scars are the end outcome of healing. They are grouped into several types, the common of which are keloid, hypertrophic and atrophic scars. The role of Krox20 in skin and hair physiology and pathology had emerged. Overexpression of Krox20 was sufficient to stimulate collagen gene expression and myofibroblast differentiation and is necessary for transforming growth factor-β (TGF-β) induced profibrotic responses. OBJECTIVE to investigate the role of Krox20 in abnormal scar pathogenesis. Hopefully, this insight can set the route for newer therapeutic approaches. MATERIALS AND METHOD This study was carried out on 30 cases [10 cases of keloid, 10 cases of atrophic scars and 10 cases with hypertrophic scars (HTS)] and 10 age and gender-matched apparently healthy subjects as a control group. Thirty biopsies were taken from perilesional areas. Evaluation of Krox20 expression was done using standard immunohistochemical technique. RESULTS Krox20 was downregulated in epidermis of scar biopsies compared to perilesional and normal skin (P=0.02) while it was overexpressed in fibroblasts in lesional scar biopsies compared to perilesional and normal skin (P<0.001). Keloid cases have significantly higher Krox20 expression in fibroblasts compared with HTS cases (P <0.001). Krox20 had significantly nucleocytoplasmic pattern of staining in scar cases compared with normal skin (P<0.001). CONCLUSION Krox20 overexpression may have a role in scar pathogenesis through up-regulation of multiple genes associated with tissue remodeling and wound healing. This may open an avenue for research for new therapies based on Krox20 inhibition.

Abstract
Adipocytes from the superficial layer of subcutaneous adipose tissue undergo cyclic de- and re-differentiation, which can significantly influence the development of skin inflammation under different cutaneous conditions. This inflammation can be connected with local loading of the reticular dermis with lipids released due to de-differentiation of adipocytes during the catagen phase of the hair follicle cycle. Alternatively, the inflammation parallels a widespread release of cathelicidin, which typically takes place in the anagen phase (especially in the presence of pathogens). Additionally, trans-differentiation of dermal adipocytes into myofibroblasts, which can occur under some pathological conditions, can be responsible for the development of collateral scarring in acne. Here, we provide an overview of such cellular conversions in the skin and discuss their possible involvement in the pathophysiology of inflammatory skin conditions, such as acne and psoriasis.

Abstract
Relevance. Scars are multi-tissue structures that significantly reduce the quality of life of the young, able-bodied population. The most socially significant variants are represented by hypertrophic and keloid postoperative scars and scars after burns, atrophic scars after acne vulgaris and striae. Growth factors, which are also used for their treatment, play a significant role in their formation and progression. The aim of this work is to summarize data on the participation of growth factors (transforming growth factor beta-1 and vascular endothelial growth factor) in the formation of a hypertrophic or atrophic scar. Materials and Methods. The study of literary sources of scientometric scientific bases was carried out. Results and Discussion . The study showed that the duration of the scarring phases preceding it is of great importance in scar formation, their prolongation leads to chronic inflammation and the attachment of an autoimmune component, an increase in the number of myofibroblasts due to inhibition of apoptosis and an increase in the synthesis of intercellular substance and immature forms of collagen, as well as thinning of the epidermis over scar. Growth factors such as growth factor beta-1 and vascular endothelial growth factor are capable of shifting the balance of these two main pathways or towards proliferative processes, contributing to an increase in the number of blood vessels in the hemomicrocirculatory bed, the number of mast cells and total cellularity, as well as, in some cases, the synthesis of keloid - that is, the formation of a hypertrophic or keloid scar. On the contrary, the prevalence of inflammatory processes leads to a decrease in cellularity, a decrease in blood vessels and intercellular substance, as well as damage to elastin and collagen fibers, forming the phenotype of an atrophic scar or striae. Conclusion. Growth factors play a key role in scar formation, contributing to an increase in the number of blood vessels in the hemomicrocirculatory bed, the number of mast cells and total cellularity, as well as, in some cases, the synthesis of keloid - that is, the formation of a hypertrophic or keloid scar.

Abstract
Dysregulation in the cutaneous wound-healing process is a consequence of alterations in the efficiency and activity of the various components involved in the healing process. This dysregulation may result in various clinical appearances of a lesion, such as skin ulcers, keloids, hypertrophic and atrophic scars. The collagen type V alpha 2 (COL5A2) gene provides a template for a component of type V collagen, found primarily within the skin basement membrane. Transforming growth factor (TGF)-β is involved in inflammation, angiogenesis, proliferation of fibroblasts, collagen synthesis and extracellular matrix remodeling. Hypertrophic scar fibroblasts possess a disrupted expression pattern of the TGF-β signaling compared to normal healing, while an increased TGF-β signaling reduces the epidermal proliferation rate, triggering atrophic scarring. In the present study, 71 female patients who had undergone planned Caesarean section, without postoperative complications, were examined. These patients were clinically and molecularly evaluated after developing scars in order to determine the role of TGF-β1 (rs201700967 and rs200230083) and COL5A2 (rs369072636) in pathological scarring. Clinical scar evaluation was carried out using SCAR and POSAS scales and genotyping was performed by RT-PCR. No statistical differences were found between the subgroups regarding the genotype and the pathological scarring, since all the patients included were wild-type allele carriers. Further investigations and a more representative study group may highlight the involvement of COL5A2 and TGF-β1 single nucleotide variants in pathological scarring.

Abstract
Previous approaches to acne management have focused on the four main factors implicated in acne, namely, androgen-mediated sebogenesis (considered integral to acne), hyperkeratinization, colonization with Cutibacterium acnes, and inflammation related to both innate and adaptive mechanisms. Recent advances have facilitated potential novel approaches to acne management, as the pathophysiology and the immunological aspects related to acne and wound healing have evolved. Particular targets that have been shown to be closely involved in acne pathophysiology and wound healing include interleukin (IL)-1β, IL-17, IL-23, and tumor necrosis factor alpha (TNFα). Biological antibodies targeting IL-1β, IL-17, IL-23, and TNFα could provide novel approaches for treating severe acne and related disorders. Acne is primarily a disease associated with sebogenesis. Monosaturated free acids are important components. Insulin growth factor 1 (IGF-1) promotes the proliferation and differentiation of sebocytes and IL-1β. Research into the microbiome may also provide insights into potential future therapeutic options for acne. Scars, both atrophic and hypertrophic, are common sequelae to acne. Risk factors associated with the development of acne scars include genetic, systemic, local, and lifestyle factors. Pro-inflammatory cytokines have been shown to play a crucial role in the development of acne-induced hypertrophic scars. Treatment for extensive inflammatory keloid scarring is limited. Surgery and postoperative radiotherapy are two possible options. Transforming growth factor-β (TGFβ), IL-6, matrix metalloproteinase (MMP), IGF-1, and B cells are found in keloid or hypertrophic scar tissues. Biological antibodies targeting these cytokines may be a potential strategy for the prevention and treatment of this type of scar in the future. Future treatment for acne should embrace approaches that target the main etiological factors of acne. In particular, specific emphasis on aggressive treatment in the acute inflammatory phase to reduce the likelihood of scarring and other clinical sequelae, such as pigmentary changes would be highly desirable. Treatment for established acne-induced sequelae should also be considered.

Abstract
BACKGROUND AND OBJECTIVES To evaluate the efficacy and safety of fractional 1064 nm Nd:YAG picosecond laser combined with intense pulsed light (IPL) in the treatment of atrophic acne scar with post-inflammatory erythema (PIE). © 2021 Wiley Periodicals LLC. STUDY DESIGN/MATERIALS AND METHODS Seventeen patients received five sessions of treatment at weeks 0, 4, 8, 12, 16 and were followed up at week 28. One half of the face was randomly treated by fractional 1064 nm Nd:YAG picosecond laser combined with IPL (FxPico + IPL), and the other by IPL alone as a control. RESULTS For the 15 patients who completed the study, the FxPico + IPL side demonstrated significant median Échelle D'évaluation clinique des cicatrices D'acné (ECCA) score improvement (P < 0.01), while IPL alone side did not (P = 0.1250). The pore counts for both sides decreased but more pore count reduction was seen on the FxPico + IPL side (P < 0.05). Better scar improvement was observed on the FxPico + IPL-treated side (P < 0.05) while no difference in erythema improvement was seen between the two sides. There was no difference between the two treatments in terms of overall satisfaction. Pain, erythema, edema, petechiae, crusting, reactive acneiform eruptions, and pruritus were common adverse effects and were mild to moderate. CONCLUSION FxPico + IPL is an effective, efficient, and safe treatment regimen for atrophic acne scars complicated by PIE.

Phase angle and Mediterranean diet in patients with acne: Two easy tools for assessing the clinical severity of disease. J Transl Med 2021; 19:171. [PMID: 33902622 PMCID: PMC8074493 DOI: 10.1186/s12967-021-02826-1] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2021] [Accepted: 04/09/2021] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Acne is a chronic, inflammatory and debilitating skin disorder. Dietary factors and nutritional status are among the exacerbating factors of acne. Phase angle (PhA), a direct measure of Bioelectrical Impedance Analysis (BIA), represents an indicator of the chronic inflammatory state. The Mediterranean diet (MD) is a healthy dietary pattern that can exert anti-inflammatory effects in several inflammatory diseases. We aimed to investigate the difference in PhA and adherence to the MD and their associations with the severity of acne in a sample of naïve treatment patients with acne compared to control group. MATERIALS In this cross-sectional, case-control, observational study, we enrolled 51 patients with acne and 51 control individuals. Body composition was evaluated by a BIA phase-sensitive system (50 kHz BIA 101 RJL, Akern Bioresearch, Florence, Italy, Akern). For adherence to the MD, we have used the PREvención con DIeta MEDiterránea (PREDIMED) questionnaire. The clinical severity of acne was assessed by using the global acne grading system (GAGS), a quantitative scoring system to assess acne severity. RESULTS Patients with acne had a worse body composition, in particular smaller PhA (p = 0.003), and a lower adherence to the MD (p < 0.001) than the control group, in spite of no differences in gender, age and BMI between the two groups. Stratifying patients with acne according to GAGS categories, both PhA (p = 0.006) and PREDIMED score (p = 0.007) decreased significantly in severe acne than mild/moderate acne. The GAGS score was negative correlations with PhA (r = - 0.478, p < 0.001) and PREDIMED score (r = - 0.504, p < 0.001). The results of the multivariate analysis showed PhA and PREDIMED score were the major determinants of GAGS score (p < 0.001). The receiver operator characteristic (ROC) analysis reporting a value of PhA of ≤ 6.1° and a PREDIMED score of ≤ 9 identified patients with acne with the highest clinical severity of the disease. CONCLUSIONS Novel correlations were reported between PhA and the degree of adherence to the MD with acne severity. Of interest, PhA and PREDIMED scores might represent possible markers of the severity of acne in a clinical setting. This study highlights how a cooperation between dermatologist and nutritionists might provide a combination key in the complex management of acne patients.

J Plast Reconstr Aesthet Surg 2021; 74:3186-3195. [PMID: 34158272 DOI: 10.1016/j.bjps.2021.03.062] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Revised: 03/07/2021] [Accepted: 03/13/2021] [Indexed: 11/18/2022]
Abstract
BACKGROUND The effect of Botulinum toxin type A (BTX-A) in treating or preventing a hypertrophic scar (HS) had been reported in clinical studies. However, the dose-effect relationship remains unclear. OBJECTIVE To study the dose-effect relationship of BTX-A intralesional monotherapy treating human HS. METHODS Six HS tissues were collected from six patients. Each tissue was segmented into 24 specimens and split into four groups: negative control (group A), 0.5U BTX-A (group B), 1U BTX-A (group C), and 2U BTX-A (group D). Six nude mice, each was prepared by implanting four specimens (one from each group) into the back for a total of 24 specimens. The process mentioned above were repeated six times. A re-entry operation was performed to obtain the specimens after 8 weeks. The weight of HS, the expression of decorin and TGF-β1, the proliferation, and migration ability of hypertrophic scar fibroblasts (HSFBs) were compared among groups. RESULTS The weight of HS, the expression of decorin and TGF-β1, the proliferation, and migration ability of HSFBs showed significant differences in groups C and D as compared to group A; there has been no statistical significance in group B. CONCLUSION BTX-A showed significant therapeutic efficacy when compared with the negative control group in a dose-dependent manner. BTX-A can reduce the weight of HS, upregulate the expression of decorin, downregulate the expression of TGF-β1, and inhibit HSFBs proliferation and migration ability. This study indicates that BTX-A intralesional monotherapy treating HS should reach a threshold dose to achieve an effective treatment, and a high dose of BTX-A is more effective than a low dose.

Abstract
To date, treatment of atrophic acne scars remains a therapeutic challenge for dermatologists, yet there is no standard option on the most effective treatment. Microneedling (MN) is a minimally invasive technology that involves repetitive skin puncture using sterile microneedles to disrupt dermal collagen that connects the scar tissue. Recent studies have demonstrated the potency of MN, such as dermaroller and fractionated microneedle radiofrequency, in the treatment of atrophic scars. The objective of this review is to evaluate systematically the current literature on MN for atrophic acne scars. A systematic search of literature was performed from PubMed, Medline, Cochrane Central, and Google Scholar databases for articles published during the last 20 years. Only randomised controlled trials (RCTs) with full‐text version of the manuscript available were included in our study. Nine RCTs were included in this review. All treatment modalities demonstrated consistent results that MN was efficacious in treating atrophic acne scars as a monotherapy or in combination with other treatments. Moreover, no serious adverse effects were reported in all studies after MN treatment. MN is a well‐tolerated and effective therapeutic modality in treating atrophic acne scars. Further research is required to validate the efficacy of MN with a larger sample size and lengthy follow‐up.

Abstract
BACKGROUND Hypertrophic scar is a common complication in would healing process, and how to effectively prevent and treat it has been a hot and difficult research issue. Previous studies have showed that botulinum toxin type A (BTA) has effects on the prevention and treatment of hypertrophic scar, but little is known about the specific mechanisms. OBJECTIVE This study aimed to explore the potential mechanisms of BTA on the inhibition of hypertrophic scar formation. METHODS Hypertrophic scar-derived human fibroblasts were cultured and then treated with transforming growth factor-β1 (TGF-β1) and various concentrations of BTA. Cell proliferation and viability were measured by CellTiter 96® AQueous One Solution Cell Proliferation Assay and trypan blue staining, respectively. The total amount of collagen was examined using Sirius red staining. Collagen I and Collagen III in the culture supernatant were evaluated by enzyme-linked immunosorbent assay. Reverse transcription-quantitative polymerase chain reaction and Western blot analysis were performed to detect the transcription and translation levels. RESULTS Our results revealed that BTA decreased the proliferation of hypertrophic scar-derived human fibroblasts. The mRNA and protein expression levels of alpha-smooth muscle actin, collagen I, and collagen III induced by TGF-β1 were inhibited by BTA in a dose-dependent manner. BTA also inhibited the phosphorylation of Smad2/3 and ERK. CONCLUSION BTA decreased the proliferation of fibroblasts and prevented overdeposition of ECM through the inhibition of the TGF-β1/Smad and ERK pathways. The findings of this study provide new scientific reference for the prevention and treatment of hypertrophic scar.

Abstract
PURPOSE Acne scarring represents a common problem that negatively impacts patients' quality of life. Different types of treatments are currently available for this dermatological condition. This study evaluates the efficacy of a new 675-nm laser source system on acne scars with the use of established parameters that guarantee minimum pain and the absence of side effects such as hyperpigmentation, hypopigmentation, and blistering. METHODS A total of 24 subjects (all women, aged 21-42 years), with Fitzpatrick skin types I-IV and facial acne scars, were treated with three sessions of a 675-nm laser system. Efficacy of treatment was evaluated using the Goodman and Baron's quantitative grading scale before and 3 months after the last treatment. RESULTS All 24 patients treated with this new 675-nm laser had significant improvement of acne scars according to Goodman and Baron's Quantitative Global Acne Scarring Grading System. No side effect has been observed except some minor erythematous reactions in three patients. CONCLUSION The 675-nm laser system we used appears to be effective and well-tolerated in patients with acne scars, and it involves a simple post-treatment management.

Abstract
BACKGROUND Hypertrophic scar results from an abnormal repair response to trauma in the skin and involves fibroblasts proliferation with increased collagen deposition. Transforming growth factor-ß1 (TGF-ß1) and TGF-ß receptor type I (TGF-ßR1) are involved in tissue repair and are increased by ubiquitin-specific protease 4 (USP4). This study aimed to investigate the effects of TGF-ßR1 and USP4 in human tissue samples of hypertrophic scar and on cell proliferation and cell migration in primary fibroblast cultures in vitro. MATERIAL AND METHODS Skin excision tissue samples with adjacent normal skin were obtained from 15 patients with hypertrophic scar, which provided tissue sections and primary fibroblast culture for analysis. Immunohistochemistry detected the expression of USP4 and TGF-ßR1 in tissue sections. MicroRNA (miRNAs) expression levels were measured by quantitative real-time polymerase chain reaction (qRT-PCR). Western blot was performed to measure protein expression levels. Cultured skin fibroblasts were investigated using immunofluorescence staining. Fibroblast proliferation, apoptosis, and migration were measured with the Cell Counting Kit-8 (CCK-8) assay, flow cytometry, and a wound-healing assay, respectively. RESULTS The expression of USP4 and TGF-ßR1 in hypertrophic scar were increased compared with normal skin. Fibroblasts cultured from hypertrophic scar tissue showed increased expression of of USP4 and TGF-ßR1. Fibroblast transfection with USP4 short-interfering RNA (siRNA) resulted in reduced fibroblast proliferation and migration, and increased apoptosis. Downregulation of USP4 inhibited the expression of TGF-ßR1 protein and increased the expression levels of Smad7 protein. CONCLUSIONS USP4 regulated the proliferation, migration, and apoptosis of hypertrophic scar fibroblasts by regulating the TGF-ß1 signaling pathway.
