Review
AIMS AND OBJECTIVES
The purpose of this study is to investigate the effectiveness and safety of oral and injectable systemic treatments, such as methotrexate, azathioprine, cyclosporine, tofacitinib, baricitinib, corticosteroids, statins, zinc, apremilast, etc., for treating vitiligo lesions.
METHOD
Databases including PubMed, Scopus, and Web of Science were meticulously searched for studies spanning from 2010 to August 2023, focusing on systemic oral and injectable therapies for vitiligo, using comprehensive keywords and search syntaxes tailored to each database. Key data extracted included study design, treatment efficacy, patient outcomes, patient satisfaction, and safety profiles.
RESULTS
In a total of 42 included studies, oral mini-pulse corticosteroid therapy (OMP) was the subject of six studies (14.2%). Minocycline was the focus of five studies (11.9%), while methotrexate, apremilast, and tofacitinib each were examined in four studies (9.5%). Antioxidants and Afamelanotide were the subjects of three studies each (7.1%). Cyclosporine, simvastatin, oral zinc, oral corticosteroids (excluding OMP) and injections, and baricitinib were each explored in two studies (4.8%). Azathioprine, mycophenolate mofetil, and Alefacept were the subjects of one study each (2.4%).
CONCLUSION
Systemic treatments for vitiligo have been successful in controlling lesions without notable side effects. OMP, Methotrexate, Azathioprine, Cyclosporine, Mycophenolate mofetil, Simvastatin, Apremilast, Minocycline, Afamelanotide, Tofacitinib, Baricitinib, Antioxidants, and oral/injectable corticosteroids are effective treatment methods. However, oral zinc and alefacept did not show effectiveness.

Review
BACKGROUND
Vitiligo, an autoimmune skin disorder linked to hormonal and genetic factors, results in reduced pigmentation due to a gradual decline in melanocyte activity. This systematic review delves into the role of dietary intervention and nutrition in managing vitiligo.
METHODS
A comprehensive search on PubMed, Google Scholar, and European PMC identified 214 studies, with 14 meeting inclusion criteria post-screening. The selected studies primarily explored the impact of dietary supplements on disease activity.
RESULTS
Heavy metal exposure, specifically Cd, Pb, and Hg, indicated potential links to heightened reactive oxygen species and vitiligo development. Conflicting evidence emerged regarding the role of trace minerals (Zn and Cu), with some studies suggesting deficiencies and others proposing excesses in vitiligo patients. Vitamins with anti-inflammatory properties like vitamin C, D, and B12, along with antioxidants, were investigated for their potential in repigmentation strategies. Additionally, polyunsaturated fatty acids (PUFAs), especially in varying types of fat consumption, were implicated. Emphasizing the need to reduce reliance on pharmacological and phototherapy interventions, the review uncovers novel roles for dietary supplements as adjuncts or flare reducers.
CONCLUSION
While dietary interventions cannot be thought of as a standalone therapy, they still make a case for being used as adjuncts. Large scale clinical trials are warranted to establish strong evidence and protocols, and might also help reduce the dependency on pharmacological methods, which come with their adverse effect profiles.

Review
Dermatoscopy is a non-invasive and cost-efficient imaging technique augmenting clinical examination in neoplastic and non-neoplastic dermatoses. Recently, novel dermatoscopic techniques based on principles of reflectance/absorption and excited fluorescence have been developed. However, comprehensive data on their applications are sparse, and terminology is inconsistent. In this systematic review, we addressed the principles of ultraviolet (UV) imaging and proposed categorization based on spectral characteristics and signal acquisition, as well as discussed documented and potential clinical applications, safety measures during examination, and limitations associated with reflectance and fluorescence dermatoscopy. A literature search was conducted in the PubMed medical database until 2 December 2023 according to PRISMA guidelines, and 28 papers fit the scope of this review, whereas additional relevant articles were included to provide broader context regarding the chosen terminology, chromophores described, safety of sub-UV/UV, and regulations for light-emitting devices. UV and sub-UV dermatoscopy, categorized into different methods on the basis of the emitted wavelength and signal acquisition process (reflectance versus fluorescence), augment conventional dermatoscopy by optimizing safety margins in melanoma, facilitating early detection of tumor recurrence, and enhancing visualization in non-neoplastic conditions, including pigmentation disorders, intertrigo, papulo-desquamative dermatoses, and beyond. The review highlights the limitations of these techniques, including difficulty in differentiating melanin from hemoglobin, challenges in evaluating uneven surfaces, and artifacts. Although UV dermatoscopy complements conventional dermatoscopy, clinicians should be aware of their peculiarities, artifacts, limitations, and safety concerns to optimize their diagnostic accuracy and ensure patient's safety.

Efficacy and Safety of Transplantation of Autologous Fat, Platelet-Rich Plasma (PRP) and Stromal Vascular Fraction (SVF) in the Treatment of Acne Scar: Systematic Review and Meta-analysis.
BACKGROUND
The efficacy and safety evaluation of the transplantation of autologous fat, platelet-rich plasma (PRP) and stromal vascular fraction (SVF) in acne scars has not been completely unified. This article will analyze and process the data of the included studies through evidence-based medicine to evaluate the efficacy and safety of autologous fat grafting, PRP and SVF for acne scar treatment, so as to provide treatment basis and strategy for the clinical treatment of acne scars.
METHODS
We searched the PubMed, Embase, Cochrane Library databases, CNKI, Wanfang and CQVIP databases for studies published during the time between the establishment of the databases through October 2022. We included studies that report autologous fat grafting, SVF and PRP for patients with acne scars. We excluded repeated publication, researches without full text, incomplete information or inability to conduct data extraction and animal experiments, case report, reviews and systematic reviews. STATA 15.1 software was used to analyze the data.
RESULTS
The findings showed that fat grafting had excellent improvement, marked improvement, moderate improvement and mild improvement rates of 36%, 27%, 18% and 18%, respectively, PRP had excellent improvement, marked improvement, moderate improvement and mild improvement rates of 0%, 26%, 47% and 25%, respectively, and the SVF had excellent improvement, marked improvement, moderate improvement and mild improvement rates of 73%, 25%, 3% and 0%, respectively. Additionally, the pooled results showed that there was no significant difference between PRP treatment and pre-treatment in Goodman and Baron scale score. However, Shetty et al. reported that Goodman and Baron scale score after fat grafting was significantly lower than pre-treatment. The results also showed that after fat grafting treatment, incidence of pain after fat grafting was 70%. After PRP treatment, in addition to pain (17%), there is a higher probability of postinflammatory hyperpigmentation (17%) and hematoma (6%). After SVF treatment, the incidence of postinflammatory hyperpigmentation and hematoma was all 0%.
CONCLUSION
Autologous fat grafting, PRP and SVF are effective for the treatment of acne scars, and the safety of autologous fat grafting, PRP and SVF is acceptable. Autologous fat grafting and SVF may be a better treatment for acne scars than PRP. However, this hypothesis still needs to be tested in the future large randomized controlled trials.

Meta-Analysis Review
AIM
This study aimed to compare the efficacy and safety of excimer laser (EL)-based combination regimens in improving repigmentation.
METHODS
A comprehensive search was conducted in PubMed, Web of Science, Cochrane Library, and Embase on July 1, 2023, to include randomized controlled trials of EL combination treatments for vitiligo that met the criteria. The primary outcome measure was a repigmentation rate ≥ 75%, and the secondary outcome measures were a repigmentation rate of ≤ 25% and adverse events.
RESULTS
Eleven studies involving 348 patients were included. Network Meta-Analysis showed that EL combined with antioxidants (SUCRA = 98.8%), EL combined with calcipotriol (SUCRA = 59.8%) and EL combined with tacalcitol (SUCRA = 59.6%) were the three optimal interventions achieving repigmentation rates ≥ 75%. EL alone (SUCRA = 77.6%), EL combined with tacalcitol (SUCRA = 61.7%) and EL combined with antioxidants (SUCRA = 57.2%) were the three interventions with the highest rates of treatment failure. Adverse events in all groups mainly included erythema, burning sensation and hyperpigmentation. Based on the results of the current study, EL combination therapies were safe with mild adverse events.
CONCLUSION
EL combined with antioxidants was the preferred regimen for vitiligo, whereas EL alone was the regimen with the highest rate of treatment failure in vitiligo.

Journal of Cosmetic Dermatology Apr 2024Tranexamic acid (TA) is a new and promising drug for the treatment of melasma. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
Tranexamic acid (TA) is a new and promising drug for the treatment of melasma.
OBJECTIVES
This network meta-analysis aims to compare the efficacy and safety of various ways of administration of TA on melasma.
METHODS
We collected researches from PubMed, EMBASE, Cochrane Library and Web of Science. Melasma area severity index (MASI) is used to evaluate the severity of melasma. After treatment with different TA administration methods, a difference in MASI is named ΔMASI. We evaluate the curative effect by comparing the ΔMASI of different TA administration methods at a certain time point.
RESULTS
At the Weeks 4, 8, and 12 and the last follow-up, the ΔMASI of oral TA combined with routine topical agents (oTA + RTA) was higher than that of intradermal TA (iTA), topical TA (tTA) as well as microneedling TA (MNsTA), with statistical significance. At the 8th week, the ΔMASI of oTA was higher than that of iTA, with statistical significance. Compared with placebo, oTA showed statistically significant differences at Week 4, while tTA, iTA, and MNsTA showed statistically significant differences starting from Week 8.
CONCLUSIONS
Among various ways of administration of TA, oTA + RTA has the best effect on melasma. In the short term, the curative effect of oTA is better than that of iTA, and the onset time of oTA is faster than that of tTA, iTA and MNsTA. In the long run, the curative effect of TA alone has nothing to do with the mode of administration.

Meta-Analysis Review
This study aimed to investigate the effects and safety of 308 nm excimer laser (308 nm EL) and tacrolimus ointment (TO) in the treatment of facial vitiligo (FV). We searched Cochrane Library, PUBMED, EMBASE, CNKI, and WANGFANG from inception to June 1, 2023. Outcomes included overall response rate (ORR), total adverse reaction rate (TARR), recurrence rate at 3-month (RR-3) and recurrence rate at 6-month (RR-6). The outcome data were presented as odds ratios (OR) with 95% confidence intervals (CI). The risk of bias was assessed by Cochrane risk-of-bias tool and data analysis was performed by RevMan 5.4 software. This study included a total of 19 trials involving 2085 patients. When comparing 308 nm EL monotherapy with 308 nm EL plus TO, significant differences in the ORR (OR = 4.29, 95% CI [2.97, 6.19], I = 0%, P < 0.001), RR-3 (OR = 0.18, 95% CI [0.05, 0.69], I = 0%, P = 0.01), and RR-6 (OR = 0.38, 95% CI [0.14, 1.03], I = 39%, P = 0.06) were found between the two managements. When comparing TO monotherapy with TO plus 308 nm EL, its results showed significant differences in the ORR (OR = 4.21, 95% CI [2.90, 6.11], I = 0%, P < 0.001), TARR (OR = 0.42, 95% CI [0.22, 0.81], I = 4%, P = 0.009), and RR-3 (OR = 0.32, 95% CI [0.01, 8.03], P = 0.49) between the two modalities. The results of this study suggest that the combination of 308 nm EL and TO is more effective than either treatment alone for the treatment of FV.

PURPOSE
The aim of this systematic review was to investigate the available data on the epidemiology of oculocutaneous albinism (OCA) around the world, and to determine whether a generalizable, worldwide prevalence figure could be proposed.
METHODS
Extensive literature search strategies were conducted, interrogating PubMed, Scopus, and Web of Science, to locate relevant literature. Ultimately 34 studies reporting original data were included for analysis.
RESULTS
Findings showed that most data were outdated, and only 6 of 34 articles (18%) were published after 2010. There were few good studies with sound methodology and large, clearly defined population samples. Only a small proportion of countries worldwide (26/193 [13%]) have produced prevalence figures for OCA. By continent, African studies were disproportionately represented (15/34 [44%]). The highest prevalence rates (range, 1 in 22 to 1 in 1300; mean, 1 in 464) were reported in population isolates. The mean prevalence from four African countries was 1 in 4264 (range, 1 in 1755 to 1 in 7900). Prevalence for three countries in Europe (mean, 1 in 12,000; range, 1 in 10,000 to 1 in 15,000) may be underestimated, as the phenotype, in fair-skinned populations, may be missed or misdiagnosed as ocular albinism or isolated visual impairment. Population rates may vary depending on local cultural factors (e.g., consanguineous matings) and may change over time.
CONCLUSIONS
The prevalence of OCA varies widely between continents and population groups, and it is often influenced by local factors. It was not possible, therefore, to determine a single, generalizable worldwide prevalence rate for OCA, although continental rates for Africa and Europe are useful.

Meta-Analysis
Efficacy and safety of compound glycyrrhizin in combination with conventional therapy in treatment of vitiligo: A systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
Vitiligo is an acquired chronic depigmentary disorder affecting approximately 0.5% to 1% of individuals worldwide. The compound glycyrrhizin (CG), a complementary medicine, has been reported for treatment of vitiligo, but the evidence has not been systematically evaluated. We systematically assessed the efficacy and safety of CG in combination with conventional therapy for the treatment of vitiligo.
METHODS
We searched Embase, Web of Science, PubMed, The Cochrane Library, Chinese BioMedical Literature Database (CBM), Wanfang Data, China National Knowledge Infrastructure (CNKI), and VIP information from inception to July 2022. Randomized controlled trials comparing CG combined with conventional therapy with conventional therapy alone for vitiligo were included in our analysis. The primary outcome was treatment response, which defined as >50% repigmentation rate of vitiligo after treatment. The secondary outcome was incidence of adverse events. Meta-analysis was performed using the Review Manager 5.4 software. Statistical heterogeneity was evaluated with chi-square and I2 statistics, dichotomous data were expressed as risk ratios (RR) with 95% confidence intervals using the Mantel-Haenszal method.
RESULTS
Thirty-nine studies enrolling with 3994 participants were subjected to this review. The results of our meta-analysis indicated that addition of CG had superior effectiveness on repigmentation rate than phototherapy (RR = 1.28; P < .001), immunosuppressant (RR = 1.76; P < .001), traditional Chinese medicine (RR = 1.38; P < .001), combination of phototherapy and immunosuppressant (RR = 1.42; P < .001), and combination of phototherapy and traditional Chinese medicine (RR = 1.37; P < .001). In addition, CG did not increase the incidence of adverse events for vitiligo (RR = 0.79; P = .05).
CONCLUSIONS
CG as a complementary medicine has a potential benefit in treatment of vitiligo. However, since the methodological flaws in the studies we included, more high-quality randomized controlled trials are warranted.
