Abstract
Keloids seem to overexpress cyclo-oxygenase-2 (COX-2), suggesting a role in its deregulated pathway in inducing an altered epithelial-mesenchymal interaction, which may be responsible for the overgrowth of dermal components resulting in scars or keloid lesions. This study aimed to evaluate the effect of Parecoxib, a COX-2 inhibitor, on cell growth in fibroblast primary cultures obtained from human keloid tissues. Tissue explants were obtained from patients who underwent intralesional excision of untreated keloids; central fractions were isolated from keloid tissues and used for establishing distinct primary cultures. Appropriate aliquots of Parecoxib, a COX-2 inhibitor were diluted to obtain the concentration used in the experimental protocols in vitro (1, 10 or 100 μM). Treatment with Parecoxib (at all concentrations) caused a significant decrease in cellular growth from 24 hours onwards, and with a maximum at 72 hours (P < .02). Moreover, at 72 hours Parecoxib significantly reduced cellular vitality. Parecoxib treatment also induced an increase in fragmented nuclei with a maximum effect at 100 μM and a significant decrease in Bcl-2 and an increase in activated caspase-3 protein levels at 72 hours compared with control untreated cultures. Our findings suggest a potential use of the COX-2 inhibitor, Parecoxib, as the therapy for keloids.

Abstract
BACKGROUND Patients with keloids are often younger than 30 years old and have darker skin. AIM To evaluate the efficacy and safety of CO2 laser therapy in the management of earlobe and helix keloids in dark subjects. METHODS A total of 21 dark patients (five men and 16 women) presented with the earlobe and ear helix keloids, with a mean age of 30.5 (±6.7) years and with phototype between III-VI, were enrolled. In order to improve their earlobe and helix keloids, all patients underwent a single session of CO2 laser therapy immediately followed by a pulsed Dye laser procedure. A single well-experienced doctor performed all treatment sessions and the response to treatment. Patients were followed-up for 6 months after termination of therapy. Clinical images were examined and collected: all patients were examined clinically and with Dermoscopy. RESULTS The majority of the patients treated show complete remission of keloid lesions. Clinical photographs show a visible aesthetic improvement of several types of keloids in dark subjects. CONCLUSIONS Our data demonstrate that this combined laser therapeutic protocol appears to be effective and well tolerated for the management of earlobe and helix keloids in dark subjects, with no high recurrence rate and avoiding the adverse effects and lengthy recovery time.

Ultrapulse Fractional CO2 Laser With Different Fluences and Densities in the Prevention of Periorbital Laceration Scars: A Split-Scar, Evaluator-Blinded Study. J Craniofac Surg 2023:00001665-990000000-00602. [PMID: 36913549 DOI: 10.1097/scs.0000000000009244] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Accepted: 11/14/2022] [Indexed: 03/14/2023] Open
Abstract
BACKGROUND Periorbital laceration can result in complex, permanent scars, and even lead to serious complications such as cicatricial ectropion. Early intervention with laser devices has been suggested as a novel modality to reduce scar formation. However, no consensus exists regarding the optimal treatment parameters for scar management. This study evaluated the efficacy and safety of ultrapulse fractional CO2 laser (UFCL) with different fluences and densities in preventing periorbital surgical scars. OBJECTIVE To assess the efficacy and safety of UFCL with different fluences and densities in the prevention of periorbital laceration scars. METHODS A prospective, randomized, blinded study was conducted on 90 patients with periorbital laceration scars of 2 weeks old. Four treatment sessions of UFCL were administered to each half of the scar at 4-week intervals, with halves treated with high fluences with low density versus low fluences with low-density treatment. Vancouver Scar Scale was used to assess the 2 portions of each individual scar at baseline, final treatment, and 6 months. The patient's 4-point satisfaction scale was used to evaluate the patient's satisfaction at baseline and 6 months. Safety was evaluated by registration of adverse events. RESULTS Eighty-two of 90 patients completed the clinical trial and follow-up. There was no significant difference in Vancouver Scar Scale and satisfaction score between different laser settings between the two groups (P > 0.05). Adverse events were minor and no long-term side effects were noted. CONCLUSIONS Early application of UFCL is a safe, strategy to significantly improve the final traumatic periorbital scar appearance. Objective evaluation of scars did not identify differences in scar appearance between high fluences with low density versus low fluences with low density of UFCL treatment.

Abstract
BACKGROUND Keloids and hypertrophic scars can affect the appearance and normal function of patients, and may severely affect patients' physical and mental health. Many methods have been used for the treatment of keloids and hypertrophic scars, there is no standardized method so far. The aim of this study was to compare the efficacy and safety of verapamil and triamcinolone acetonide (TAC) in treating keloids and hypertrophic scars. METHODS All studies from their inception date up to August 2022 were searched using four databases (PubMed, Cochrane Library, MEDLINE, and EMBASE). The weighted mean differences and the risk ratio were calculated for comparing continuous variables and dichotomous variables, respectively. RESULTS A total of nine randomized controlled trials involving 567 patients were identified. This meta-analysis indicated that TAC group showed significantly better effects compared with verapamil group in the reduction of height at 3 and 9 weeks, pliability at 3, 9, and 18 weeks, vascularity at 3, 6, 9, 12, 18, and 24 weeks, whereas verapamil group showed significantly better effects compared with TAC group in the reduction of pliability at 21 and 24 weeks. Verapamil group showed a significantly lower incidence of skin atrophy, telangiectasia, and hypopigmentation compared with TAC group. However, the incidence of burning sensation in verapamil group was higher than that in TAC group. CONCLUSION Concerning the treatment of keloids and hypertrophic scars, TAC was more effective than verapamil for improving vascularity; TAC was superior to verapamil in improving height within 9 weeks of treatment; TAC produced superior result for improving pliability within 18 weeks of treatment, whereas verapamil produced superior result between 18 and 24 weeks of treatment. Verapamil had fewer adverse events than TAC and can be used as a safer alternative for the treatment of keloids and hypertrophic scars.

Abstract
Keloids are skin lesions which result from an aberration in the physiological healing process marked with overgrowth of collagen fibers. Keloid of the ear is cosmetically challenging and has an increased chance of re-growth. To minimize recurrence, pressure therapy in combination with other treatment forms has been used. Various techniques have been used to fabricate a passive or active stent. This report presents a fully digital workflow to fabricate an ear stent after intralesional excision and skin autografting of an extensive recurrence of a keloid lesion of the left ear involving the helix, antihelix, scapha and conchal bowl.

Abstract
To evaluate the efficacy and safety of laser alone therapy and laser combination therapy (mainly combined with other kinds of laser or steroids) for keloid.PubMed, Embase and Web of Science were searched for relevant articles from inception to June 2020. Comprehensive Meta-Analysis software 2.0 (CMA) was used to perform the meta-analysis.A total of 29 articles were included in this meta-analysis. During the mean follow-up of 14 (1-84) months, the overall improvement rates of baseline Vancouver scar scale (VSS) score and itch were 0.454 (95%CI 0.351-0.561, I2 = 0) and 0.786 (95%CI 0.613-0.895, I2 = 0) in the laser combination therapy group. The improvement rates of scar height and flexibility in the laser combination therapy group were 0.629 (95%CI 0.519-0.727, I2 = 52.089) and 0.784 (95%CI 0.251-0.975, I2 = 89.420). The average improvement rate of the scar score in laser combination therapy was 0.338 (0.201-0.510); however, there were insufficient data for laser alone therapy comparison. The laser combination therapy had a greater pain improvement rate, 0.580 (0.389-0.750) versus 0.420 (0.224-0.645), compared to laser alone therapy, and a greater degree of good or excellent (> 50%) improvement in the overall scar, 0.636 (95%CI 0.347-0.852) versus 0.149 (95%CI 0.032-0.482), with laser alone therapy. Moreover, a lower regrowth rate of 0.187 (0.129-0.263) versus 0.249 (0.060-0.631), a lower post-treatment pigmentation rate of 0.125 (0.091-0.169) versus 0.135 (0.058-0.282), and a lower infection rate of 0.047 (0.009-0.209) versus 0.076 (0.012-0.351) were observed in the laser combination therapy compared with those rates in the laser alone therapy.The overall effect of laser combination therapy was better than that of laser alone therapy, and the incidence of adverse reactions was lower in laser combination therapy than in laser alone therapy.

Abstract
Keloid often recur after treatment, and recent studies in keloid management favor the combination therapy of laser-assisted drug delivery over monotherapy. Unfortunately, the previous researches lack long-term follow-up. In this prospective study, 41 individuals with refractory keloids underwent eight treatment sessions at 4 weeks intervals consisting of ultrapulse fractional carbon dioxide laser (UFCL), followed by postoperative application topical triamcinolone acetonide (40 mg/ml). Four follow-up moments were chosen, with follow-up of 24 months. The effects of combination therapy on scar pliability, thickness, relief, vascularization, surface area, pain, and itchiness were examined by means of the Patient and Observer Scar Assessment Scale (POSAS). 38 patients completed the full 24 months of follow-up after the whole treatment. The results reveal a fast and abiding improvement of keloid scars after the combination therapy. The mean keloid POSAS scores showed a decreasing trend in subsequent times. All POSAS components improved significantly between baseline and 24 months after start of therapy (P < .05). Long-term follow-up results demonstrate that combination keloid therapy using UFCL and tropical triamcinolone has overall significant improvement and low recurrence rate with a long-term stable results.

Abstract
BACKGROUND Needle-free jet injection implements kinetic energy of liquid jet for transcutaneous delivery of drugs into soft tissues. Combination therapy of intralesional 5-fluorouracil and triamcinolone offers efficacious treatment for keloids with a reduced adverse effect of the drug monotherapy. This study evaluates safety and efficacy of the drug combination administered to keloid scars via intralesional jet injections. METHODS A retrospective analysis of the keloid treatments was performed. Efficacy was assessed by reviewing pre- and post-treatment scores of the Vancouver Scar Scale (VSS) and Patient and Observer Scar Assessment Scale (POSAS) and by comparing baseline and photographs taken 3 months after the treatments. Safety and tolerability were collected and analyzed. RESULTS Twenty-one subjects (M/F = 11/10) with 39 keloids received the treatments. Treatments were well-tolerated by all patients at mean injection pain of 2.0 ± 1.0 per Numeric Pain Rating Scale (NPRS). Self-resolved lesion ulceration was observed in 4 patients. Post-treatment evaluation demonstrated a 53% decrease in total VSS score (P < 0.05) and in all sub-categories. Mean patient score of POSAS decreased in the color, stiffness, thickness, and irregularity components. Pain and pruritus lessened by 69% and 79% (P < 0.05 in both), respectively, among the patients with complaints prior to the treatment. Independent reviewers reported an average 51%-75% reduction in keloids. CONCLUSIONS Improved appearance of keloids and symptomatic relief was achieved by intralesional administration of combined 5-fluorouracil and corticosteroid through the high-pressure jet injections. The synergy between the drug combination and the jet physical impact provided clinical effect.

Abstract
BACKGROUND/OBJECTIVE Keloids represent a functional and esthetic burden and can be particularly challenging to treat. Various topical, injectable, and ablative therapies exist but are associated with significant recurrence if used alone. We wanted to evaluate the long-term efficacy of multimodal therapy in pediatric patients treated for keloids at the Sainte-Justine University Hospital Center. METHODS We conducted a retrospective case study of 21 children with 21 keloids treated between April 2006 and April 2016. The following combination of treatments was studied: surgical excision, carbon dioxide (CO2 ) laser therapy on the surgical site, and triamcinolone acetonide (TAC) intralesional injections during surgery and follow-up. Depending on the site treated, pressure garments and/or topical silicone were also used. RESULTS Of the 21 patients initially treated, four were lost to follow-up. Of the 17 patients who had adequate follow-up (mean duration 18 months, with periodic reassessments and additional TAC injections if needed), 6 (35%) had some recurrence, with remission in three of them following subsequent treatment and three lost to follow-up. In summary, 14 (82.4%) of the patients with adequate follow-up had complete clearance of the keloid. However, this must be interpreted in light of the fact there was a significant loss of follow-up (33.3%) from the initial cohort. CONCLUSION Our results are in agreement with other recent studies that demonstrate the need for multimodal therapy with combined methods in order to achieve long-term remission. A randomized controlled trial would be necessary to assess the real benefit of this treatment combination in children.

Abstract
Keloids are pathological scars that grow over time and extend beyond the initial site of injury after impaired wound healing. These scars frequently recur and rarely regress. They are aesthetically disfiguring, can cause pain, itching, discomfort as well as psychological stress, often affecting quality of life. Many treatment modalities, including surgical and non-surgical, have been explored and have been reported to be beneficial; however, none have been absolutely satisfactory or optimal for the treatment of all keloid subtypes to date. This poses a major challenge to clinicians. Often, a combinational therapeutic approach appears to offer the best results with higher patient satisfaction compared to monotherapy. The aetiopathogenesis of keloids is not fully elucidated; however, with recent advances in molecular biology and genetics, insight is being gained on the complex process of scar formation and hence new therapeutic and management options for keloids. In this paper, we explore the literature and summarise the general concepts surrounding keloid development and review both current (corticosteroids, surgical excision, silicone-based products, pressure therapy, radiotherapy, cryotherapy, laser therapy, imiquimod and 5-fluorouracil) and emerging (stem cell therapy, mitomycin C, verapamil, interferons, bleomycin, botulinum toxin type A and angiotensin-converting enzyme inhibitors) treatments. Increased knowledge and understanding in this area may potentially lead to the discovery and development of novel therapeutic options that are more efficacious for all keloid types. LAY SUMMARY Keloids are problematic scars that are difficult to treat and manage. The aetiopathogenesis of keloids is not clear; however, recent advances in molecular biology and genetics are beginning to shed light on the underlying mechanisms implicated in keloid scar formation which will hopefully lead to the development of treatment options for all keloid types. This review summarises current and emerging therapies.

Abstract
BACKGROUND Pathological scars are unattractive and may significantly impair the patient's quality of life. Current treatments provide inconsistent results, and none may be regarded as definitive. Recently, an auto-cross-linked hyaluronic acid (HA) formulation, IAL-SYSTEM ACP, featuring a long residence time and an enhanced safety profile, has been successfully used to prevent surgical adhesions, treat tendon lesions and rejuvenate the face and the décolletage. This study aims to preliminarily investigate whether IAL-SYSTEM ACP may also be effective in treating pathological scars resulting from burns, trauma or iatrogenic causes. METHODS Patients presenting one pathological scar were prospectively recruited and treated with two IAL-SYSTEM ACP injections carried out two weeks apart. Scar improvement was measured comparing the patient and observer scar assessment scale (POSAS) scores collected before treatment (T0) and 90 days after the second injection (T90) using nonparametric tests. The effect of age and scar type over score variation was investigated through quantile regression analysis. RESULTS Forty-one patients, 10 women and 31 men (median age, 34 years) were recruited. No patient dropped out, and no significant adverse event was observed. At T90, the median observer total score decreased by 11 units (- 77.5%) and the median patient total score decreased by 15 units (- 73.7%). The difference was significant (p < 0.001) in both cases. Traumatic injuries and young patient's age were the most significant predictors of a positive treatment outcome. CONCLUSIONS Treatment of pathological scars by two IAL-SYSTEM ACP injections, carried out two weeks apart, may provide significant clinical benefits. These findings should be the subject of further investigations. LEVEL OF EVIDENCE IV This journal requires that authors assign a level of evidence to each article.

Abstract
Keloid scars are common and have a predilection for young, ethnic skin often with a family history. Keloids can be painful and pruritic and cause significant emotional distress when particularly visible or prominent. In this article, we review the evidence underlying the use of laser- and energy-based devices for treatment of keloid scars, either as monotherapy or in conjunction with other therapies such as corticosteroids, surgery and silicone gel in the treatment of keloid scars.

Abstract
OBJECTIVE The aim of this study was to investigate the potential impact of multiple preoperative and intraoperative variables on the outcome of partial cricotracheal resection and tracheal resection anastomosis (PCTR/TRA). METHODS The study was conducted on 35 consecutive patients of grade III and IV upper tracheal stenosis with or without subglottic involvement. The indication of PCTR/TRA was post intubation stenosis in all patients. Overall complications (major and minor) occurred in 18 patients. Perioperative mortality occurred in 1 patient. Anastomotic complications do not always mean failure of surgery. They may indicate one or more interventions; such as removal of granulation tissue or dilatation of restenosis, with good results in most cases. RESULTS At the end of treatment, 30 (85.7%) patients were decannulated successfully with effortless breathing and with good phonation and swallowing. Several perioperative factors were found to have a significant impact on the outcome of PCTR/TRA. Of these factors, comorbidities had the most significant negative impact, and indeed all the three patients who had comorbidities, were not successfully decannulated. Duration of intubation, length of resected segment and previous open airway interventions was reported to have a significant negative impact on the outcome of surgery. CONCLUSION PCTR/TRA for treatment of post traumatic subglottic or upper tracheal stenosis has a high success rate, especially in healthy patients without comorbidities, and without previous open airway interventions.

Abstract
Keloids are common in the Asian population. Multiple or huge keloids can appear on the chest wall because of its tendency to develop acne, sebaceous cyst, etc. It is difficult to find an ideal treatment for keloids in this area due to the limit of local soft tissues and higher recurrence rate. This study aims at establishing an individualized protocol that could be easily applied according to the size and number of chest wall keloids.A total of 445 patients received various methods (4 protocols) of treatment in our department from September 2006 to September 2012 according to the size and number of their chest wall keloids. All of the patients received adjuvant radiotherapy in our hospital. Patient and Observer Scar Assessment Scale (POSAS) was used to assess the treatment effect by both doctors and patients. With mean follow-up time of 13 months (range: 6-18 months), 362 patients participated in the assessment of POSAS with doctors.Both the doctors and the patients themselves used POSAS to evaluate the treatment effect. The recurrence rate was 0.83%. There was an obvious significant difference (P < 0.001) between the before-surgery score and the after-surgery score from both doctors and patients, indicating that both doctors and patients were satisfied with the treatment effect.Our preliminary clinical result indicates that good clinical results could be achieved by choosing the proper method in this algorithm for Chinese patients with chest wall keloids. This algorithm could play a guiding role for surgeons when dealing with chest wall keloid treatment.

Abstract
Background The wound healing process is complex and still poorly understood. Sericin is a silk protein synthesized by silk worms (Bombyx mori). The objective of this study was to evaluate in vivo wound healing effects of a sericin-containing gel formulation in an incision wound model in rats. Material/Methods Twenty-eight Wistar-Albino rats were divided into 4 groups (n=7). No intervention or treatment was applied to the Intact control group. For other groups, a dorsal skin flap (9×3 cm) was drawn and pulled up with sharp dissection. The Sham operated group received no treatment. The Placebo group received placebo gel without sericin applied to the incision area once a day from day 0 to day 9. The Sericin Group 3 received 1% sericin gel applied to the incision area once a day from day 0 to day 9. Hematoxylin and eosin stain was applied for histological analysis and Mallory-Azan staining was applied for histoimmunochemical analysis of antibodies and iNOS (inducible nitric oxide synthase), and desmin was applied to paraffin sections of skin wound specimens. Parameters of oxidative stress were measured in the wound area. Results Epidermal thickness and vascularization were increased, and hair root degeneration, edema, cellular infiltration, collagen discoloration, and necrosis were decreased in Sericin group in comparison to the Placebo group and the Sham operated group. Malonyldialdehyde (MDA) levels were decreased, but superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) activities were increased in the sericin group. Conclusions We found that sericin had significant positive effects on wound healing and antioxidant activity. Sericin-based formulations can improve healing of incision wounds.

Abstract
INTRODUCTION Wound healing can be characterized as underhealing, as in the setting of chronic wounds, or overhealing, occurring with hypertrophic scar formation after burn injury. Topical therapies targeting specific biochemical and molecular pathways represent a promising avenue for improving and, in some cases normalizing, the healing process. AREAS COVERED A brief overview of both normal and pathological wound healing has been provided, along with a review of the current clinical guidelines and treatment modalities for chronic wounds, burn wounds and scar formation. Next, the major avenues for wound healing drugs, along with drugs currently in development, are discussed. Finally, potential challenges to further drug development, and future research directions are discussed. EXPERT OPINION The large body of research concerning wound healing pathophysiology has provided multiple targets for topical therapies. Growth factor therapies with the ability to be targeted for localized release in the wound microenvironment are most promising, particularly when they modulate processes in the proliferative phase of wound healing.

Abstract
BACKGROUND Keloids are an overgrowth of fibrotic tissue outside the original boundaries of an injury and occur secondary to defective wound healing. Keloids often have a functional, aesthetic, or psychosocial impact on patients as highlighted by quality-of-life studies. OBJECTIVES Our goal is to provide clinicians and scientists an overview of the data available on laser and light-based therapies for treatment of keloids, and highlight emerging light-based therapeutic technologies and the evidence available to support their use. METHODS We employed the following search strategy to identify the clinical evidence reported in the biomedical literature: in November 2012, we searched PubMed.gov, Ovid MEDLINE, Embase and Cochrane Reviews (1980-present) for published randomized clinical trials, clinical studies, case series and case reports related to the treatment of keloids. The search terms we utilized were 'keloid(s)' AND 'laser' OR 'light-emitting diode' (LED) OR 'photodynamic therapy' (PDT) OR 'intense pulsed light' OR 'low level light' OR 'phototherapy.' RESULTS Our search yielded 347 unique articles. Of these, 33 articles met our inclusion and exclusion criteria. CONCLUSION We qualitatively conclude that laser and light-based treatment modalities may achieve favourable patient outcomes. Clinical studies using CO2 laser are more prevalent in current literature and a combination regimen may be an adequate ablative approach. Adding light-based treatments, such as LED phototherapy or PDT, to laser treatment regimens may enhance patient outcomes. Lasers and other light-based technology have introduced new ways to manage keloids that may result in improved aesthetic and symptomatic outcomes and decreased keloid recurrence.

Abstract
Keloid disease (KD) is a common, benign, dermal fibroproliferative growth of unknown aetiology. Lesions tend to grow over time; they often recur following therapy and do not regress spontaneously. KD causes considerable discomfort due to pain, pruritus and inflammation, and a significant psychosocial impact with reduced quality of life. It is unique to humans and occurrence is higher in individuals with dark, pigmented, ethnic skin. There is a strong familial heritability, with a high ethnic predisposition in individuals of African, Asian and Hispanic descent. High recurrence rates and unknown resolution rates present a major problem for both the patient and clinician. Many treatment modalities exist; however, there is no single advocated therapy. Therefore, the aim of this review was to explore the most current literature regarding the range of treatment options for KD and to offer a structured approach in the management of KD, based on evidence and experience, to aid clinicians in their current practice. A focused history involving careful evaluation of the patient's symptoms, signs, quality of life and psychosocial well-being should direct targeted therapy, complemented with regular follow-up and re-evaluation. Many treatment modalities, such as intralesional steroid injection, silicone gel application, cryotherapy, lasers, 5-fluorouracil and, relatively recently, photodynamic therapy, are currently being used in clinical practice for the management of KD. Combination therapies have also been shown to be beneficial. However, there is a lack of robust, randomized, level-one, evidence-controlled trials evaluating these treatment options. Management of KD in ethnic pigmented skin remains a clinical challenge. Thus, a strategic approach with structured assessment, targeted therapy and focus on prevention of recurrence is highly recommended. Quality evidence is essential in order to tailor treatment effectively for the ethnic patient presenting with KD.
