American Journal of Clinical Dermatology Nov 2021Patients with vitiligo experience reduced quality of life.
BACKGROUND
Patients with vitiligo experience reduced quality of life.
OBJECTIVE
To comprehensively describe the available evidence for psychosocial burden in vitiligo.
METHODS
A systematic review of observational studies and clinical trials identified using PubMed, EMBASE, Scopus, and the Cochrane databases was performed through 1 March, 2021, to assess psychosocial comorbidities in vitiligo. Two independent reviewers performed an assessment of articles and extracted data for qualitative synthesis.
RESULTS
Included studies (N = 168) were published between 1979 and 1 March, 2021; 72.6% were published since 2010. Disorders including or related to depression (41 studies, 0.1-62.3%) and anxiety (20 studies, 1.9-67.9%) were the most commonly reported. The most prevalent psychosocial comorbidities were feelings of stigmatization (eight studies, 17.3-100%), adjustment disorders (12 studies, 4-93.9%), sleep disturbance (seven studies, 4.6-89.0%), relationship difficulties including sexual dysfunction (ten studies, 2.0-81.8%), and avoidance or restriction behavior (12.5-76%). The prevalence of most psychosocial comorbidities was significantly higher vs healthy individuals. Factors associated with a significantly higher burden included female sex, visible or genital lesions, age < 30 years (particularly adolescents), and greater body surface area involvement, among others. The most commonly reported patient coping strategy was lesion concealment.
LIMITATIONS
Available studies were heterogeneous and often had limited details; additionally, publication bias is possible.
CONCLUSIONS
The results of this systematic review show that vitiligo greatly affects psychosocial well-being. The extent of psychosocial comorbidities supports the use of multidisciplinary treatment strategies and education to address the vitiligo-associated burden of disease.

Journal of the American Academy of... Sep 2021Multiple studies have reported on dermoscopic structures in basal cell carcinoma (BCC) and its subtypes, with varying results.
BACKGROUND
Multiple studies have reported on dermoscopic structures in basal cell carcinoma (BCC) and its subtypes, with varying results.
OBJECTIVE
To systematically review the prevalence of dermoscopic structures in BCC and its subtypes.
METHODS
Databases and reference lists were searched for relevant trials according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies were assessed for the relative proportion of BCC dermoscopic features. Random-effects models were used to estimate summary effect sizes.
RESULTS
Included were 31 studies consisting of 5950 BCCs. The most common dermoscopic features seen in BCC were arborizing vessels (59%), shiny white structures (49%), and large blue-grey ovoid nests (34%). Arborizing vessels, ulceration, and blue-grey ovoid nests and globules were most common in nodular BCC; short-fine telangiectasia, multiple small erosions, and leaf-like, spoke wheel and concentric structures in superficial BCC; porcelain white areas and arborizing vessels in morpheaform BCC; and arborizing vessels and ulceration in infiltrative BCC.
LIMITATIONS
Studies had significant heterogeneity. Studies reporting BCC histopathologic subtypes did not provide clinical data on pigmentation of lesions.
CONCLUSION
In addition to arborizing vessels, shiny white structures are a common feature of BCC. A constellation of dermoscopic features may aid in differentiating between BCC histopathologic subtypes.

Meta-Analysis
INTRODUCTION
Vitiligo is an autoimmune disorder characterized by progressive loss of melanocytes, leading to cutaneous depigmentation. Vitiligo has significant psychosocial impacts on patients and is challenging to manage with limited treatment options. Recent studies have suggested promising results for JAK1/3 inhibitors including tofacitinib and ruxolitinib.
OBJECTIVE
To determine the expected response of vitiligo to JAK inhibitor therapy and factors which influence response rates.
METHODS
A systematic review and meta-analysis was performed according to PRISMA guidelines. Good response was defined as repigmentation >50% or a 'good' or 'excellent' outcome as described by authors. Partial response was defined as some repigmentation <50%.
RESULTS
From the 9 eligible studies, individual patient data from 45 cases were pooled. Good response was achieved in 57.8%, partial response in 22.2%, and none or minimal response in 20% of cases. When subgrouped according to site, facial vitiligo had the highest good response rate (70%), compared to extremities (27.3%) and torso/non-sun exposed areas (13.6%). Concurrent phototherapy was significant associated with higher rates of good overall response ( < .001) and good facial response ( < .001).
CONCLUSIONS
There is promising low-quality evidence regarding the effectiveness of JAK inhibitors in vitiligo. Concurrent UVB phototherapy appears to improve efficacy of JAK inhibitors for vitiligo.

Meta-Analysis
BACKGROUND
Microneedling as an adjuvant to topical medications has shown promising but variable results in the treatment of melasma.
OBJECTIVE
To conduct a systematic review and meta-analysis on the efficacy of microneedling as an adjuvant to topical therapies for the treatment of melasma.
METHODS
This study followed PRISMA guidelines. All comparative, prospective studies on the use of topical interventions with microneedling for the treatment of melasma were included. Studies involving radiofrequency microneedling were excluded.
RESULTS
Twelve eligible studies comprising 459 patients from 7 different countries were included. Topical therapies included topical tranexamic acid, vitamin C, platelet-rich plasma, non-hydroquinone-based depigmentation serums, and hydroquinone-based depigmenting agents. Topical therapy with microneedling improved melasma severity with a large effect (standardized mean difference >0.8) beyond 8 weeks, with best results seen at 12 weeks. Compared to topical therapy alone, topical therapy with microneedling resulted in an additional improvement in melasma severity with a moderate effect at 8 weeks and a large effect at 12-16 weeks. Microneedling was well tolerated across studies, with no serious adverse events reported.
LIMITATIONS
Heterogeneity in study designs did not allow for a comparison of the efficacy of various topical therapies with microneedling.
CONCLUSION
Microneedling is useful adjuvant to topical therapies for the treatment of melasma.

Background: Melasma is an acquired skin disease characterized by symmetric hyperpigmentation on sun-exposed areas, particularly on the face. Recently, there has been tremendous scientific interest in novel, safe, and effective topical agents to manage melasma. Objective: To evaluate topical treatments for melasma and provide evidence-based recommendations for clinical use and further research. Methods: We performed a systematic review of randomized controlled trials (RCTs) on topical agents for the treatment of melasma on March 4th, 2019 using PRISMA guidelines. Clinical recommendations were based on the American College of Physicians guidelines. Results: After screening, we identified 35 original RCTs using azelaic acid, cysteamine, epidermal growth factor, hydroquinone (liposomal-delivered), lignin peroxidase, mulberry extract, niacinamide, Rumex occidentalis, triple combination therapy, tranexamic acid, 4-n-butylresorcinol, glycolic acid, kojic acid, aloe vera, ascorbic acid, dioic acid, ellagic acid and arbutin, flutamide, parsley, or zinc sulfate for melasma. Conclusions: Cysteamine, triple combination therapy, and tranexamic acid received strong clinical recommendations for the treatment of melasma. Cysteamine has excellent efficacy and is reported to have anti-cancer properties, but has not been directly compared with hydroquinone. Triple combination agents and tranexamic acid are effective, but carry theoretical risks for ochronosis and thrombosis, respectively. Natural compounds are associated with low risk for adverse events, but more research is needed to determine the efficacy, optimal formulation, and appropriate concentration of novel treatments.

Journal of Cosmetic Dermatology Oct 2023Topical azelaic acid (AA) is indicated for acne and rosacea, but there is some evidence for its use for other dermatological conditions. (Review)
Review
BACKGROUND
Topical azelaic acid (AA) is indicated for acne and rosacea, but there is some evidence for its use for other dermatological conditions.
AIMS
To assess the effectiveness and safety of topical AA for acne vulgaris, rosacea, hyperpigmentation/melasma, and skin aging.
METHODS
RCTs of at least 6 weeks' treatment duration were eligible for inclusion. Databases including MEDLINE, Embase, CINAHL, and ClinicalTrials.gov were searched up to December 2022. Two reviewers were involved in all stages of the systematic review process.
RESULTS
Forty-three RCTs met the inclusion criteria. Meta-analyses within 20 rosacea studies demonstrated that erythema severity, inflammatory lesion counts, overall improvement, and treatment success (achieving skin clarity) were significantly improved with AA compared with vehicle after 12 weeks. AA was more effective than metronidazole 0.75% for improved erythema severity, overall improvement, and inflammatory lesion counts. Sixteen acne studies suggest that AA is more effective than vehicle for improving global assessments and reducing acne severity. AA 20% also significantly reduced more lesions than erythromycin gel. Within seven melasma studies, AA 20% was significantly better than vehicle for both severity and global improvement. AA 20% demonstrated significantly better results compared with hydroquinone 2% for global improvement. Very few significant differences between AA and comparators were observed for commonly reported adverse events. No eligible RCTs were found that evaluated skin aging.
CONCLUSIONS
AA is more effective than vehicle for rosacea, acne and melasma. Comparisons between AA and other treatments were often equivalent. Where there is equivalence, AA may be a good option for some clinical situations. RCT evidence is needed to evaluate the effectiveness of AA on skin aging.

Review
Terra firma-forme dermatosis (TFFD) is an acquired pigmentation disorder that promptly regresses after applying isopropyl alcohol 70%. The clinical presentation ranges from patches of brownish discoloration to velvety hyperkeratotic plaques. Critical analyses of current data are lacking, so etiologies, pathogenesis, and disease associations are still debated in the literature. A literature search was done in the PubMed and Google Scholar databases to identify the published papers reporting clinical cases of TFFD. Of 102 papers screened, 64 met the including criteria. Overall, the records of 256 patients presenting a mean age of 18.34 years and a female:male ratio of 1:37 were reviewed. The present article aims to provide a key point-summary regarding the clinical outcome, associated comorbidities, pathogenesis, histopathology, dermoscopy, and therapeutic modalities of TFFD.

Review
INTRODUCTION
Vitiligo is an acquired skin disorder characterised by white (depigmented) patches in the skin, due to the loss of functioning melanocytes. The extent and distribution of vitiligo often changes during the course of a person's lifetime and its progression is unpredictable.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of surgical interventions for vitiligo in adults and in children? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2014 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found four studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: blister grafts, cultured cellular transplantation, non-cultured cellular transplantation, punch/mini grafts, and split thickness skin grafts.

BACKGROUND
Melasma is a common relapsing hyperpigmentation disorder, which is often difficult to treat. Platelet-rich plasma (PRP) is a novel modality often used to treat acne scars, androgenic alopecia, chronic wounds, and skin rejuvenation. Recently, it has had a promising role in the treatment of melasma.
OBJECTIVE
To review the published evidence on the efficacy and safety of PRP in the treatment of melasma.
MATERIALS AND METHODS
A systematic review was performed. A meta-analysis could not be performed because of methodological differences across studies and data heterogeneity.
RESULTS
Seven studies were fulfilled and analyzed. Most studies used intradermal injections of PRP and have shown significant improvement in melasma. Microneedling mediated delivery of PRP has been tried in melasma with good results. A single study showed no additional benefit of PRP in patients treated with topical tranexamic acid. Another study showed no benefit of intense pulsed light in patients treated with intradermal PRP.
CONCLUSION
Platelet-rich plasma inhibits the melanin synthesis through its various components acting through several mechanisms. It demonstrates a moderate grade of recommendation according to the Oxford Center for Evidence-Based Medicine 2011 standards.

Review
BACKGROUND
Xeroderma pigmentosum (XP) is a rare autosomal recessive disorder of UV radiation-induced damage repair that is characterized by photosensitivity and a propensity for developing, among many others, skin cancers at an early age. This systematic review focused on the correlation between the clinical, pathological, and genetic aspects of XP and skin cancer.
METHODS
A systematic review was conducted through a literature search of online databases PubMed, Cochrane Library, SciELO, and Google Scholar. Search terms were "Xeroderma pigmentosum", "XP", "XPC", "Nucleotide excision repair", "NER", "POLH", "Dry pigmented skin", and "UV sensitive syndrome" meshed with the terms "Skin cancer", "Melanoma", and "NMSC".
RESULTS
After 504 abstracts screening, 13 full-text articles were assessed for eligibility, and 3 of them were excluded. Ten articles were selected for qualitative assessment.
CONCLUSIONS
Patients with XP usually suffer shorter lives due to skin cancer and neurodegenerative disease. Deletion/alteration of a distinct gene allele can produce different types of cancer. The XPC and XP-E variants are more likely to have skin cancer than patients in other complement groups, and the most common cause of death for these patients is skin cancer (metastatic melanoma or invasive SCC). Still, aggressive preventative measures to minimize UV radiation exposure can retard the course of the disease and improve the quality of life.
