Aesthetic Surgery Journal. Open Forum Sep 2021Medical tattooing is often applied in the context of plastic, aesthetic, and reconstructive surgery to help achieve the best cosmetic outcome.
BACKGROUND
Medical tattooing is often applied in the context of plastic, aesthetic, and reconstructive surgery to help achieve the best cosmetic outcome.
OBJECTIVES
This article reviews various conditions that medical tattooing has been empirically studied in terms of patient satisfaction outcomes, makes practice recommendations, and suggests future directions for research.
METHODS
This review was performed following the PRISMA guidelines. Studies were included if the tattooing application was associated with a medical condition and if outcome data were provided using at least a case series methodology. Where no cohort or clinical series exist, case examples are used from the literature and the author's practice to illustrate emerging medical tattooing applications that need further evaluation.
RESULTS
Eighteen studies met the inclusion criteria and addressed the following conditions: baldness, vitiligo, scars from incisions, lacerations or burns, and nipple-areola complex reconstruction.
CONCLUSIONS
The application of medical tattooing has shown high levels of patient satisfaction across conditions. The practice recommendation grade is "B" or recommend since the level of evidence for these interventions ranged from III to IV according to the American Society of Plastic Surgeons guidelines. This means clinicians can consider this treatment alternative, but they should be alert to new information and be sensitive to patient preferences. Recommendations are made for reporting future research including clearly describing procedural details, identifying the professional performing the procedure, increased use of standardized outcome measures, and that satisfaction ratings be assessed by someone independent of the health service provider. Further research using randomized controlled trial methodology with waitlist controls is needed.

Meta-Analysis
BACKGROUND
Vitiligo is a disfiguring skin disease with profound psychosocial impacts, such as anxiety, but the reported effect sizes of associations vary. We aimed to conduct a meta-analysis to quantify the strength of association between anxiety and vitiligo and to estimate the prevalence of anxiety among individuals with vitiligo.
METHODS
A systematic literature search was performed in five online databases (MEDLINE, Embase, Web of Science, Cochrane Library, and PsycINFO) from inception until March 20, 2020. All of the eligible studies were comprehensively reviewed, and all of the available data were analyzed according to our predefined criteria.
RESULTS
Twenty-one studies involving 3259 patients in 11 countries were included in this meta-analysis. Compared with the healthy control group, patients with vitiligo often had concomitant anxiety (OR = 6.14 [95% CI: 3.35-11.24], = 30.1%). The pooled prevalence of anxiety in female patients was significantly higher than that in males (OR = 2.24 [95% CI: 1.31-3.84], = 0.0%). Subgroup analysis showed that the pooled prevalence of clinical anxiety disorder and anxiety symptoms was 12% (95% CI: 7%-16%, = 76.3%) and 34% (95% CI: 21%-46%, = 94.7%), respectively. No publication bias has been detected by Begg's funnel plot and Egger's test.
CONCLUSION
Patients with vitiligo have high anxiety comorbidity, with female predominance. Dermatologists and psychiatrists should be vigilant to the presence of anxiety, apply appropriate interventions to reduce the psychological impacts in a timely manner, and thus promote recovery in vitiligo patients. However, due to some objective limitations (poor information about the OR and diversity in assessment tools among included studies), findings should be interpreted with caution.

Non-celiac gluten sensitivity is often clinically indistinguishable from celiac disease, and patients show improvement or resolution of their symptoms with a gluten-free diet. In contrast to celiac disease, the effects of gluten on the skin and hair in the context of non-celiac gluten sensitivity are not as clear. This review aims to describe the impact of gluten on the skin and hair in patients with non-celiac gluten sensitivity and those without a definitive celiac disease diagnosis. A literature search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) reporting guidelines for systematic reviews. Forty-two publications met inclusion criteria with five studies describing the skin manifestations of non-celiac gluten sensitivity. Trials identifying the impact of a gluten-free diet on skin disease, as well as dermatologic conditions and their associations with antigliadin antibodies were also identified. Dermatologic manifestations in patients with non-celiac gluten sensitivity vary and may be non-specific. It may be appropriate for some of these patients with skin manifestations to trial a gluten-free diet. Dermatologic conditions that may respond positively to a gluten-free diet include psoriasis, atopic dermatitis, vitiligo, and palmoplantar pustulosis, while linear IgA disease does not appear to improve with this dietary change.

Meta-Analysis
BACKGROUND
The serum Vitamin D status in patients with vitiligo is ambiguous when compared to controls. A systematic review and updated meta-analysis were conducted to evaluate the association between Vitamin D and vitiligo.
METHODS
Relevant studies were identified by searching PubMed and other databases. The random effects model was used to obtain standardized mean differences and pooled correlation coefficients. Meta-regression and sub-group analyses were conducted to explore heterogeneity. The presence of publication bias and the study robustness were tested using funnel plot and sensitivity analyses, respectively.
RESULTS
This meta-analysis finally included 31 studies. Compared with controls, vitiligo patients showed significantly decreased serum Vitamin D levels (standardized mean difference = -1.03; p < 0.0001). The sub-group analysis showed that vitiligo patients with indoor/urban work had a significantly lower Vitamin D level when compared to their outdoor/rural counterparts (standardized mean differences = -0.45; p = 0.03). The sensitivity analysis indicated that no single study had a significant influence on the overall outcome, suggesting the robustness of this meta-analysis.
STUDY LIMITATIONS
Varied sample sizes and heterogeneous study populations from different countries are the limitations of this study. However, the between-study heterogeneity has been addressed by the random-effects model with meta-regression and sensitivity analyses.
CONCLUSIONS
This meta-analysis showed significantly decreased Vitamin D level in vitiligo, and its association with indoor/outdoor type of work of vitiligo patients. This study highlights the need to assess Vitamin D status for improving its level in vitiligo.

Review
INTRODUCTION
Vitiligo is disfiguring and devastating condition that can humans feel stigmatic and devalued. Melasma is a general condition of hyperpigmentation particularly involving the face. The pigmentation disorders of vitiligo (hypopigmentation or de-pigmentation) and melasma (Hypermelanosis) are common among the world's population (around 1% for vitiligo).
OBJECTIVE
The identification of medicinal plants used in the treatment of vitiligo and hypermelanosis. A systematic literature review on harms associated with the medicinal plants used in the treatment of vitiligo and hypermelanosis. To review and summarize information on reported adverse drug reactions (ADRs) associated with these medicinal plants contained in (where access is available) national and global individual case safety report databases.
METHODS
A systematic review of the literature with special reference to all types of clinical trial and case reports using biomedical databases including Medline, EMBASE, Scopus, International Pharmaceutical Abstracts and so forth to identify medicinal plants alone or as an adjuvant with other treatments and their safety/tolerability in the treatment of vitiligo and Hypermelanosis. Other sources of this search were medicinal plants text books, pharmacopoeias and authentic websites discussing possible treatments for vitiligo/hypermelanosis. It also included databases such as VigiAccess containing data from spontaneous reporting schemes for ADRs.
RESULTS
A total of 55 articles (47 clinical trials and 8 case reports) met the inclusion criteria. Some trials did not reported safety information, some did report, but not very well. Reports of blistering, erythema, acute hepatitis and mutagenesis with . Adverse effects of erythema (mild to severe), phototoxic reactions, mild raise in liver transaminases, gastrointestinal disturbances, burns, itching, scaling, depigmented macules, pruritis, and giddiness with the use of psoralens. Khellin-related erythema, perilesional hyperpigmentation, gastrointestinal disturbances, mild raise in liver transaminases and orthostatic complaints. Infrequent side effects with Ginkgo biloba. Lower grade of erythema and edema reported with the use of
CONCLUSION
Primarily the retrieved clinical studies were efficacy oriented and safety parameters were secondary in priority whilst the general protocol of clinical trials requires the screening of drugs/medicinal plants on the basis of safety studies before testing the clinical aspects of efficacy. Thereby it is recommended that efficacy studies may be followed once the safety has been established for a particular medicinal plant in treating vitiligo and hypermelanosis.

Comparative Study Meta-Analysis
IMPORTANCE
Surgical interventions are a key part of the therapeutic arsenal, especially in refractory and stable vitiligo. Comparison of treatment outcomes between the different surgical procedures and their respective adverse effects has not been adequately studied.
OBJECTIVE
To investigate the reported treatment response following different surgical modalities in patients with vitiligo.
DATA SOURCES
A comprehensive search of the MEDLINE, Embase, Web of Science, and Cochrane Library databases from the date of database inception to April 18, 2020, was conducted. The key search terms used were vitiligo, surgery, autologous, transplantation, punch, suction blister, and graft.
STUDY SELECTION
Of 1365 studies initially identified, the full texts of 358 articles were assessed for eligibility. A total of 117 studies were identified in which punch grafting (n = 19), thin skin grafting (n = 10), suction blister grafting (n = 29), noncultured epidermal cell suspension (n = 45), follicular cell suspension (n = 9), and cultured epidermal cell suspension (n = 17) were used.
DATA EXTRACTION AND SYNTHESIS
Three reviewers independently extracted data on study design, patients, intervention characteristics, and outcomes. Random effects meta-analyses using generic inverse-variance weighting were performed.
MAIN OUTCOMES AND MEASURES
The primary outcomes were the rates of greater than 90%, 75%, and 50% repigmentation response. These rates were calculated by dividing the number of participants in an individual study who showed the corresponding repigmentation by the total number of participants who completed the study. The secondary outcomes were the factors associated with treatment response to the surgical intervention.
RESULTS
Among the 117 unique studies and 8776 unique patients included in the analysis, rate of repigmentation of greater than 90% for surgical interventions was 52.69% (95% CI, 46.87%-58.50%) and 45.76% (95% CI, 30.67%-60.85%) for punch grafting, 72.08% (95% CI, 54.26%-89.89%) for thin skin grafting, 61.68% (95% CI, 47.44%-75.92%) for suction blister grafting, 47.51% (95% CI, 37.00%-58.03%) for noncultured epidermal cell suspension, 36.24% (95% CI, 18.92%-53.57%) for noncultured follicular cell suspension, and 56.82% (95% CI, 48.93%-64.71%) for cultured epidermal cell suspension. The rate of repigmentation of greater than 50% after any surgical intervention was 81.01% (95% CI, 78.18%-83.84%). In meta-regression analyses, the treatment response was associated with patient age (estimated slope, -1.1418), subtype of vitiligo (estimated slope, 0.3047), and anatomical sites (estimated slope, -0.4050).
CONCLUSIONS AND RELEVANCE
The findings of this systematic review and meta-analysis suggest that surgical intervention can be an effective option for refractory stable vitiligo. An appropriate procedure should be recommended based on patient age, site and size of the lesion, and costs.

Review
Regulatory T cells (Tregs) are a subset of T cells responsible for the regulation of immune responses, thereby maintaining immune homeostasis and providing immune tolerance to both self and non-self-antigens. An increasing number of studies revealed Treg numbers and functions in a variety of autoimmune diseases. Treg deficiency can cause the development of several autoimmune skin diseases including vitiligo, alopecia areata, pemphigoid and pemphigus, psoriasis, and systemic sclerosis. Many clinical trials have been performed for autoimmune conditions using polyclonal Tregs, but efficiency can be significantly improved using antigen-specific Tregs engineered using T cell receptor (TCR) or chimeric antigen receptor (CAR) constructs. In this review, we systematically reviewed altered frequencies, impaired functions, and phenotypic features of Tregs in autoimmune skin conditions. We also summarized new advances in TCR and CAR based antigen-specific Tregs tested both in animal models and in clinics. The advantages and limitations of each approach were carefully discussed emphasizing possible clinical relevance to patients with autoimmune skin diseases. Moreover, we have reviewed potential approaches for engineering antigen-specific Tregs, and strategies for overcoming possible hurdles in clinical applications. Thereby, antigen-specific Tregs can be infused using autologous adoptive cell transfer to restore Treg numbers and to provide local immune tolerance for autoimmune skin disorders.

Stabilized vitiligo resistant to conventional therapy (e.g. segmental vitiligo) and piebaldism lesions can be treated with autologous cellular grafting techniques, such as non-cultured cell suspension transplantation (NCST) and cultured melanocyte transplantation (CMT). These methods are preferred when treating larger surface areas due to the small amount of donor skin needed. However, the donor to recipient expansion ratios and outcomes reported in studies with cellular grafting vary widely, and to date, no overview or guideline exists on the optimal ratio. The aim of our study was to obtain an overview of the various expansion ratios used in cellular grafting and to identify whether expansion ratios affect repigmentation and colour match. We performed a systematic literature search in MEDLINE and EMBASE to review clinical studies that reported the expansion ratio and repigmentation after cellular grafting. We included 31 eligible clinical studies with 1591 patients in total. Our study provides an overview of various expansion ratios used in cellular grafting for vitiligo and piebaldism, which varied from 1:1 up to 1:100. We found expansion ratios between 1:1 and 1:10 for studies investigating NCST and from 1:20 to 1:100 in studies evaluating CMT. Pooled analyses of studies with the same expansion ratio and repigmentation thresholds showed that when using the lowest (1:3) expansion ratio, the proportion of lesions achieving >50% or >75% repigmentation after NCST was significantly better than when using the highest (1:10) expansion ratio (χ P = 0.000 and χ P = 0.006, respectively). Less than half of our included studies stated the colour match between different expansion ratios, and results were variable. In conclusion, the results of our study indicate that higher expansion ratios lead to lower repigmentation percentages after NCST treatment. This should be taken into consideration while determining which expansion ratio to use for treating a patient.

Meta-Analysis
Presently, there is an explosion in various uses of platelet-rich plasma (PRP). Several trials comparing combination therapy with PRP vs monotherapy for vitiligo have been published. However, evidence-based information is not enough for making well-informed decisions. This study aimed to evaluate several combination therapy strategies for vitiligo. EMBASE, PubMed, Web of Science, Cochrane Library and Google Scholar databases were searched to identify randomised controlled trials comparing combination therapy with PRP vs monotherapy for vitiligo. Eleven studies with 670 cases were included. Compared with monotherapy, clinical improvement of repigmentation was significantly higher in 308-nm excimer laser combined with PRP (odds rate for response rate of 50%-100% repigmentation, 4.47; 95% CI, 2.47-8.10; P < .00001) and in fractional carbon dioxide laser combined with PRP (mean difference for mean improvement grades of repigmentation, 1.61; 95% CI, 0.24-2.99; P = .02), respectively. Compared to monotherapy, there is no higher clinical improvement in strategies of PRP combined with narrowband-ultraviolet B or non-cultured epidermal cell suspension. Trivial adverse events were reported. This meta-analysis summarises current evidence that PRP combined with 308-nm excimer laser or fractional carbon dioxide laser is effective and safe for vitiligo. This systematic review and meta-analysis aims to evaluate the effectiveness and safety of several combination therapy strategies with PRP in the treatment of vitiligo. The response rate of repigmentation and mean improvement grades of repigmentation were mainly used for qualitative assessment. PRP combined with 308-nm excimer laser or fractional carbon dioxide laser is effective and safe for vitiligo due to its healing and regenerative properties.

Meta-Analysis
BACKGROUND
Vitiligo is an acquired depigmenting skin disease which is often accompanied by mental distress. There are numerous studies dedicated to local and global prevalence of depression in patients with vitiligo but anxiety has not been recognized as a major mental problem within named population. We aimed to evaluate the prevalence of anxiety among patients with vitiligo from different countries and to compare it with patients suffering from eczema, psoriasis, and acne.
METHODS
In November 2019, we conducted a systematic search for observational studies that examined the prevalence of anxiety in vitiligo patients. Fifteen studies comprising 1176 patients with vitiligo were included to our systematic review.
RESULTS
The general prevalence of anxiety among vitiligo patients was equal to 35.8%. Statistically significant difference in anxiety rates was found among female and male patients (47.32% vs 42.4%) (P = 0.03), but the clinical relevance of this issue remains arguable. In addition, the pooled odds ratio among vitiligo and non-vitiligo patients did not indicate a statistical significance among patients coming from different continents.
CONCLUSIONS
The pooled prevalence of anxiety among vitiligo patients worldwide was comparable to other severe skin disorders. This finding accentuates the necessity of anxiety awareness in management of patients with skin diseases.
