Wang Y, Chen Y, Wu J, Shi X. BMP1 Promotes Keloid by Inducing Fibroblast Inflammation and Fibrogenesis. J Cell Biochem 2024:e30609. [PMID: 38860429 DOI: 10.1002/jcb.30609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 05/11/2024] [Accepted: 05/24/2024] [Indexed: 06/12/2024]
Abstract
Keloid is a typical fibrotic and inflammatory skin disease with unclear mechanisms and few therapeutic targets. In this study, we found that BMP1 was significantly increased in a collagen high-expressing subtype of fibroblast by reanalyzing a public single-cell RNA-sequence data set of keloid. The number of BMP1-positive fibroblast cells was increased in keloid fibrotic loci. Increased levels of BMP1 were further validated in the skin tissues and fibroblasts from keloid patients. Additionally, a positive correlation between BMP1 and the Keloid Area and Severity Index was found in keloid patients. In vitro analysis revealed collagen production, the phosphorylation levels of p65, and the IL-1β secretion decreased in BMP1 interfered keloid fibroblasts. Besides, the knockdown of BMP1 inhibited the growth and migration of keloid fibroblast cells. Mechanistically, BMP1 inhibition downregulated the noncanonical TGF-β pathways, including p-p38 and p-ERK1/2 signaling. Furthermore, we found the delivery of BMP1 siRNAs could significantly alleviate keloid in human keloid-bearing nude mice. Collectively, our results indicated that BMP1 exhibited various pathogenic effects on keloids as promoting cell proliferation, migration, inflammation, and ECM deposition of fibroblast cells by regulating the noncanonical TGF-β/p38 MAPK, and TGF-β/ERK pathways. BMP1-lowing strategies may appear as a potential new therapeutic target for keloid.

Abstract
There is uncertainty whether postoperative application of paper tape (PT) improves scar aesthetics and reduces wound closure complications. This study aimed to review and assess the quality of applicable findings from studies investigating PT's efficacy. We queried PubMed and SCOPUS using the search terms "(("paper tape") AND (wound OR closure OR heal* OR complication OR skin OR prevent* OR scar*))." We excluded articles that were duplicates, basic science, or not clinically relevant. We assessed the level of evidence for each article using the American Society of Plastic Surgeons (ASPS) Rating Levels of Evidence and Grading Recommendations for Therapeutic Studies, ranging from I (highest) to V (lowest). Of 186 publications reviewed, we included eight studies in the literature review. Five of these studies reported statistically significant positive outcomes on scar aesthetics and wound closure associated with using PT. Using the ASPS rating system, we found that two studies were Level I, three studies were Level II, two studies were Level IV, and one study was Level V. Notably, heterogeneity in the study designs limited outcome comparison. The data from the studies included in this literature review support using PT to optimize scar and wound management. The lack of higher levels of evidence, however, suggests the need for additional randomized controlled trials to rigorously evaluate patient outcomes when using PT compared with other forms of adhesive dressings.

Abstract
Wound healing occurs as a response to disruption of the epidermis and dermis. It is an intricate and well-orchestrated response with the goal to restore skin integrity and function. However, in hundreds of millions of patients, skin wound healing results in abnormal scarring, including keloid lesions or hypertrophic scarring. Although the underlying mechanisms of hypertrophic scars and keloid lesions are not well defined, evidence suggests that the changes in the extracellular matrix are perpetuated by ongoing inflammation in susceptible individuals, resulting in a fibrotic phenotype. The lesions then become established, with ongoing deposition of excess disordered collagen. Not only can abnormal scarring be debilitating and painful, it can also cause functional impairment and profound changes in appearance, thereby substantially affecting patients' lives. Despite the vast demand on patient health and the medical society, very little progress has been made in the care of patients with abnormal scarring. To improve the outcome of pathological scarring, standardized and innovative approaches are required.

Abstract
The US population is becoming increasingly diverse, yet patients of color remain underrepresented in dermatology. The lack of diverse images in dermatologic learning materials can lead to discomfort in treating patients of color, delayed, and missed diagnoses. In this review, we compare and contrast the clinical presentation, management, and special considerations of common skin conditions between patients of color and white patients as well as provide a visual representation of these differences.

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
Dissecting cellulitis of the scalp (DCS) is a rare skin disease and understudied. The aim of the study was to collect the demographic, clinical features and laboratory tests of patients with DCS in a dermatology outpatient clinic. A cross-sectional study was conducted in a department of dermatology in Beijing. Patients whose diagnoses have included DCS were selected from July 2021 to December 2021. DCS patients were stratified according to whether they were follicular occlusion triad (FOT) or not. There were 169 patients with DCS included. All 169 patients were male, and the median patient age was 32 years. The most common comorbidities in this study were seborrheic dermatitis (10.65%). Over 1/3 of patients had elevated white blood cell (WBC) and neutrophil counts, and 12 of 18 patients had dyslipidemia. CD8+ T cell counts increased in 15 of 26 patients while CD4+ T/CD8+ T ratios were all normal. DCS mainly affects men in their thirties. More research about DCS is needed to clarify the clinical significance of laboratory tests.

Abstract
PURPOSE The aim of this study is to utilize the Manchester scar scale (MSS) and ultrasound in investigating the association between uterine wall defects and cutaneous scar characteristics after cesarean section (CS). METHODS This is a prospective cohort study. The degree of myometrial loss was quantified by calculating a residual myometrial thickness (RMT) ratio as a percentage of RMT to the pre-cesarean anterior uterine wall thickness. Cutaneous scar assessment was performed according to the MSS. Spearman's correlation and the Kruskal-Wallis test with a cut-off value of p < 0.05 were used for statistical analysis. RESULTS Two hundred forty seven women, of which 2.4% had an Asian, 3.6% an Afro-American, 82% a Caucasian and 12% a Mediterranean background, were recruited. The RMT ratio ranged between 11.9 and 100% with a median of 55.8% and an average of 56%. MSS scores ranged from 4 to 13 with a median of 5 and an average of 6. Spearman's correlation between MSS and RMT ratio show a rho of - 0.01 with a p value of 0.8. The correlation between MSS and RMT ratio within the four ethnical groups showed a p value between 0.3 and 0.8 and a rho between 0.8 and - 0.8. The Kruskal-Wallis test showed an eta2 of 0.13 and a p value of 0.0002 for the effect of ethnicity on MSS and an eta2 of 0.009 and a p value of 0.68 for the effect of ethnicity on the RMT ratio. CONCLUSION CS laparotomy scars heal differently between ethnical groups, but generally with satisfying results. Ethnicity does not affect myometrial healing and scar appearance does not reflect myometrial healing after CS. Thus, separate uterine sonographic assessment is recommended.

Abstract
Introduction les pathologies du cuir chevelu sont fonction de plusieurs facteurs dont l´ethnie, le sexe ou l´âge. Chez le sujet noir, elles peuvent être induites par des facteurs intrinsèques et extrinsèques. Très peu d´études ont été réalisées dans ce groupe ethnique résidant en Afrique noire d´où l´objectif de notre enquête qui était de documenter les aspects épidémiologiques et cliniques des pathologies du cuir cheveu en fonction du sexe et de l´âge dans un service de dermatologie à Cotonou (Bénin). Méthodes l´étude était rétrospective et descriptive sur 7 ans et a concerné tous les dossiers des nouveaux patients reçus en consultation dans le service de dermatologie-vénérologie du Centre National Hospitalier et Universitaire (CNHU) de Cotonou dont le motif de consultation était une pathologie exclusive du cuir chevelu. Les caractéristiques épidémiologiques et cliniques ont été saisies et analysées avec le logiciel EPI-Info 7. Résultats la prévalence des pathologies du cuir chevelu était de 2,4% (181/7554). Les enfants (0-18 ans) représentaient 38,7%, soit 70 patients et les adultes 61,3%, soit 111 patients. Les enfants de 0-10 ans (54; 29,8%) et les adultes de 25-40 ans (51; 28,2%) étaient les plus touchées. Le sex-ratio était de 1,8. Les dermatoses diagnostiquées étaient non alopéciantes (10; 5,5%) ou alopéciantes (171; 94,5%) dont 82,9% (151/171) de non cicatricielles et 11,7% (20/171) de cicatricielles. Les pathologies les plus fréquentes étaient la teigne (41; 22,6%) prédominant chez les garçons de 0-10 ans, les folliculites chroniques non cicatricielles (39; 21,5%) en majorité chez les garçons de 0-5 ans et les hommes de 19-40 ans, la pelade (38; 21%) dans les deux sexes surtout entre 6-10 ans et 25-40 ans, l´alopécie de traction (17; 9,4%) exclusivement chez les femmes et surtout dans la tranche de 25-40 ans, la folliculite fibrosante de la nuque (12; 6,6%) exclusivement chez les hommes à partir de 19 ans jusqu´à 50 ans, la trichotillomanie (9; 5%) dans les deux sexes, surtout chez les enfants de 6-10 ans et chez les adultes de 25-40 ans, la folliculite épilante de Quinquaud (6; 3,3%) uniformément dans les deux sexes et surtout entre 25-40 ans. Conclusion les pathologies du cuir chevelu atteignaient avec prédilection les patients de sexe masculin avant la puberté et les adultes jeunes. Elles étaient réparties par ordre décroissant en dermatoses alopéciantes non cicatricielles, dermatoses alopéciantes cicatricielles et dermatoses non alopéciantes.

Abstract
Asian hair is known for its straightness, dark pigmentation, and large diameter. The cuticle layer in Asians is thicker with more compact cuticle cells than that in Caucasians. Asian hair generally exhibits the strongest mechanical properties, and its cross-sectional area is determined greatly by genetic variations, particularly from the ectodysplasin A receptor gene. However, knowledge on Asian hair remains unclear with limited studies. This article aimed to review and summarize the characteristics and properties of Asian hair. It also aimed to discuss hair disorders including linear lupus panniculitis and pseudocyst of the scalp that occur distinctively in Asian populations.

Abstract
BACKGROUND Hair loss on the central scalp commonly occurs among African American (AA) women and can pose substantial psychosocial burdens. The causes of hair loss remain obscure, although type 2 diabetes has been hypothesized to increase the risk of hair loss. The objective of the present study was to prospectively estimate the association between type 2 diabetes and severe central hair loss in AA women. METHODS The Black Women's Health Study has collected data on medical and lifestyle factors, including diagnosis of type 2 diabetes, biennially since 1995 from AA women across the United States. The present analysis was based on responses from 5389 women to an online hair loss questionnaire in 2015. Respondents indicated severity of central hair loss on a validated six-item photographic scale; the highest levels, levels 3 to 5, were designated as severe. We used Cox proportional hazards models to estimate multivariable hazard ratios and 95% confidence intervals (CIs) for type 2 diabetes in relation to severe central hair loss. RESULTS During the follow-up period, 850 cases of severe hair loss occurred. The multivariable hazard ratio for severe hair loss associated with diabetes was 1.68 (95% CI, 1.38-2.06) overall, and 2.05 (95% CI, 1.48-2.85) for diabetes duration of ≥ 10 years. CONCLUSION Type 2 diabetes was associated with an increased risk of severe central scalp hair loss in AA women. Patients with type 2 diabetes should be followed closely for central scalp hair loss so that appropriate treatment can be offered.

Abstract
OBJECTIVE Cutaneous disorders can impact on the psycho-social well-being of children and adults alike, which has been reviewed elsewhere (Body Image 27, 2018 and 98). The present review sets out to evaluate progressions in skin masking and camouflaging techniques together with evaluating the efficacy of these. There does not appear to have been any recent reviews about innovations in skin camouflaging techniques. METHODS Using the National Centre for Biotechnology Information PubMed database, a search was made for all studies published between 2000 and 2019 that met defined inclusion criteria. A total of seven relevant publications were identified. RESULTS Of the seven studies identified, skin camouflaging improved quality of life in three studies and reduced anxiety, depression and social isolation in others. Of the camouflaging methods used, liquidized simulated second skin technology (Microskin™) appears to look particularly promising. This method of colour matching and a spray/stippling application uses a technology that binds to the epidermis of the skin helping to overcome previous concerns about the colour, coverage and application of camouflage and masking bases. Two studies showed that this innovative mode of camouflaging raised confidence, feelings of happiness and social experiences in children and adolescents with burn scarring. Very few studies reported drawbacks of camouflaging techniques, with limited colour matches and 'itching' appearing to be the main shortcomings. New technologies now appear to be addressing these. CONCLUSION Results show that there is wide variation in the quality and modes of skin camouflaging. Of the methods used, simulated second skin technology appears to be an important and effective therapy for individuals with cutaneous skin disorders. Training schemes along with increased awareness of this technique must now be communicated to medical professionals who come into contact with children and adults who could benefit physically, psychologically and socially from this therapy.

Abstract
BACKGROUND The application of heat, used to straighten the typically coiled hair, has long been hypothesized to play a role in the etiologic factor for central centrifugal cicatricial alopecia (CCCA). The aim of this study was to evaluate the effect of thermal hair straightening on hair loss pattern in Asian women exist. MATERIALS AND METHODS Thirty-five patients with hair loss who have been using hair straightening devices and 25 patients with telogen effluvium were enrolled in this prospective study. Laboratory analysis and dermatoscopic findings were used to compare these groups. RESULTS The peripilar white halo around hairs, peripilar dark/gray halo around follicular orifices, the predominance of a single hair perifollicular unit (FU), hair diameter diversity, the thin miniaturized hair, interfollicular pinpoint white dots, and white patches were statistically higher in hair straightener group (P < 0.001). White patches of the scalp increased by the time of the application of these devices (P < 0.01). White patches of vertex region were significantly higher than the midfrontal region (P < 0.01). CONCLUSION The common side effects of thermal hot comb strengtheners' were summarized as damage to the hair shaft; decreasing in the brightness of the hair, burns, and scars on the scalp; and lastly CCCA-like hair loss.

Abstract
BACKGROUND Differentiating scarring and nonscarring alopecia poses a diagnostic dilemma for clinicians, with histopathology used to distinguish. The extent to which dermatologists are able to clinically classify alopecia has not been evaluated. METHODS A retrospective study of pathology reports on 458 patients was used to calculate a kappa coefficient to correlate clinical presence of scarring or nonscarring alopecia to histopathologic presence of scarring or nonscarring. A multivariate analysis was performed to assess for associations with scarring. RESULTS The kappa correlation coefficient was 0.59 (P < 0.0001), indicating moderate agreement and varied by race and sex. There were 15 times higher odds of making the clinical diagnosis of scarring alopecia (OR 14.64 95% CI [8.64-24.18]; P < 0.001), and this increased with age. CONCLUSIONS These results suggest that clinical exam is moderately reliable in distinguishing between scarring and nonscarring alopecia. Our results highlight the need for education and diagnostic schemata for evaluation of alopecia based on gender and in skin of color.

Abstract
Glaucoma is the leading cause of irreversible blindness worldwide and is a particular burden on the Asian population. Glaucoma surgeries such as trabeculectomy and glaucoma drainage implants are routinely performed to lower intraocular pressure (IOP) to prevent disease progression. However, scarring of the filtering bleb limits their long-term success and Asian eyes are more at risk. Although this is so, many existing studies have been done on Caucasian patients, but few have focused solely on Asian patients. Intraoperative anti-metabolites such as Mitomycin-C (MMC) and 5-Fluorouracil (5-FU) are the current mainstay of adjunctive treatments to reduce scarring, and in this review, we evaluate the evolution, benefits and side effects of these agents. Recently, newer methods of wound modulation including anti-vascular endothelial growth factor (VEGF) agents and collagen implants are also being investigated as part of a multi-pronged approach to tackle this problem. Some opportunities exist to limit scarring post-operatively, but it is an ongoing battle.

Abstract
Scarring is an extensive problem in burn care, and treatment can be especially complicated in cases of hypertrophic scarring. Contraction is an important factor in scarring but the contribution of different cell types remains unclear. We have investigated the contractile behavior of keratinocytes, melanocytes and fibroblasts by using an in vitro collagen gel assay aimed at identifying a modulating role of melanocytes in keratinocyte-mediated contraction. Cells were seeded on a collagen type I gel substrate and the change in gel dimensions were measured over time. Hematoxylin & Eosin-staining and immunohistochemistry against pan-cytokeratin and microphthalmia-associated transcription factor showed that melanocytes integrated between keratinocytes and remained there throughout the experiments. Keratinocyte- and fibroblast-seeded gels contracted significantly over time, whereas melanocyte-seeded gels did not. Co-culture assays showed that melanocytes mitigate the keratinocyte-dependent contraction (significantly slower and 18-32% less). Fibroblasts augmented the contraction in most assays (approximately 6% more). Non-contact co-cultures showed some influence on the keratinocyte-dependent contraction. Results show that mechanisms attributable to melanocytes, but not fibroblasts, can mitigate keratinocyte contractile behavior. Contact-dependent mechanisms are stronger modulators than non-contact dependent mechanisms, but both modes carry significance to the contraction modulation of keratinocytes. Further investigations are required to determine the mechanisms involved and to determine the utility of melanocytes beyond hypopigmentation in improved clinical regimes of burn wounds and wound healing.
