Meta-Analysis
Onychomycosis or fungal nail infection is one of the most common fungal infections. Nearly 50% of all nail disorders are caused by fungi. This systematic review and meta-analysis was conducted to determine the prevalence of onychomycosis across Iran. We searched English and Persian databases for studies reporting the epidemiologic features of onychomycosis in Iranian people from January 2000 to December 2018. Literature search revealed 307 studies, of which 24 studies met the eligibility criteria. In order to identifying the existence of publication bias among studies, funnel plots were used. The results of the meta-analysis were visualized as a forest plot representing the prevalence estimates of each study. Heterogeneity was also analyzed using the I, Chi, and Tau statistics. A high level of I and Chi was obtained among studies, which provides evidence of notable heterogeneity between studies. The results of current study revealed that the highest prevalence of onychomycosis was related to Mazandaran and Tehran provinces, respectively. As in the literature hypothesized shift in etiologic agents from yeasts to dermatophytes or molds could not be confirmed. Females were affected more frequently than males and in both sexes the highest incidence of infection occurrence was at the ages of >50 years. It seems the highest prevalence of onychomycosis in Mazandaran and Tehran provinces is due to the concentration of specialist doctors and research centers in these two provinces compared with others which leads to more detection and more care of the disease. Therefore, further educational strategies in order to accurate diagnosis in other provinces is necessary to reduce the risk of onychomycosis in Iran.

Experimental alternative ex vivo models that simulate infectious processes in vivo are of fundamental importance for the evaluation of new drugs, since in some cases, their execution does not depend on the approval of an ethics committee in research. Although studies using alternative infectious models to evaluate the efficacy of antifungal molecules have been increasingly described and reported, there is no critical consensus that establishes the most appropriate ones regarding the type of infection. Numerous studies contemplate ex vivo protocols of fungal infections on nails, corneas, dentinal tubules and skin and reveal counterpoints and concordances not yet finely confronted. In this minireview, we propose a critical analysis of the main ex vivo models of fungal infections for the evaluation of new antifungal candidates for both topical and systemic use, as opposed to the advantages and disadvantages of the traditional in vivo models employed in preclinical research.

Meta-Analysis
Laser therapy for onychomycosis is emerging but its efficacy remains unestablished. To examine current evidence on efficacy of laser treatment of onychomycosis. A systematic review and one-arm meta-analysis, including all prospective clinical trials, identified on PubMed, Cochrane Library, and EMBASE databases. Trials with participants as unit of analysis (UOA), n = 13, were analyzed separately from trials with nails as UOA, n = 7. Summary proportions and 95% confidence intervals (95% CI) were calculated. Outcomes were mycological cure, clinical improvement, or complete cure. Twenty-two prospective trials (four randomized controlled trials and 18 uncontrolled trials) with a total of 755 participants were analyzed. Summary proportions with 95% CI for participants as UOA were mycological cure 70.4%, 95% CI 52.2-83.8%; clinical improvement 67.2%, 95% CI 43.2-84.7%; and complete cure 7.2%, 95% CI 1.9-23.5%. High statistical heterogeneity was detected (mycological cure I = 88%, P < 0.01; clinical improvement I = 69%, P < 0.01; complete cure I = 60%, P = 0.11). The current level of evidence is limited and with high heterogeneity, making it difficult to assess the true efficacy of laser treatment for onychomycosis. Larger randomized controlled trials with well-defined methodology are warranted.

Many patients with a visible chronic skin disease experience discrimination and stigmatization. This results in psychosocial impairments in addition to the burden of disease and emphasizes the urgency to implement effective stigma-reduction strategies. To synthesize what is known globally about effective interventions to reduce stigma associated with visible chronic skin diseases, a systematic review was conducted. Four electronic databases were searched until May 2018. Studies evaluating interventions to reduce stigmatization in patients with visible chronic skin diseases and applying at least one stigma-related outcome measure were included. Data were extracted on study design, country, study population, outcome measures and main findings. Results were subsequently synthesized in a narrative review. Critical Appraisal Skills Programme tools were used to assess study quality. Nineteen studies were included in the review. Study design was very heterogeneous and study quality rather poor. Thirteen studies addresses patients with leprosy in low- and middle-income countries, and one study each targeted patients with onychomycosis, leg ulcer, facial disfigurement, atopic dermatitis, vitiligo and alopecia. Evaluated interventions were mainly multi-faceted incorporating more than one type of intervention. While 10 studies focused on the reduction in self-stigma and 4 on the reduction in public stigma, another 5 studies aimed at reducing both. The present review revealed a lack of high-quality studies on effective approaches to reduce stigmatization of patients with visible chronic skin diseases. Development and evaluation of intervention formats to adequately address stigma is essential to promote patients' health and well-being.

Meta-Analysis
BACKGROUND
Onychomycosis is a fungal infection of the nail caused by dermatophytes, yeasts and nondermatophyte moulds that accounts for approximately 50% of all nail-related disease.
OBJECTIVES
This study aims to assess the effectiveness and safety of monotherapy and combination treatments for toenail onychomycosis using a network meta-analysis (NMA).
METHODS
Quality of evidence was assessed using Cochrane-compliant rules and the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. Efficacy and safety outcomes were compared using a random-effects NMA to estimate pooled odds ratios (ORs) of direct and indirect comparisons among oral and topical treatments (PROSPERO 2015: CRD42018086912). There were not enough eligible combination and device-based therapy trials to include in the NMA.
RESULTS
Of 77 randomized controlled trials, 26 were included in the ORs (8136 patients). There were no significant inconsistencies between the direct and indirect evidence. Relative effects show that the odds of mycological cure with continuous terbinafine 250 mg or continuous itraconazole 200 mg are significantly greater than topical treatments. Fluconazole, pulse regimens of terbinafine and itraconazole, and topical treatments did not differ significantly in the odds of achieving mycological cure. The ORs of adverse events occurring with oral or topical treatments were not significantly different from each other. For mycological cure, evidence was of moderate or high quality while evidence ranged from very low to high quality for adverse events.
CONCLUSIONS
Our review suggests that oral and topical treatments for toenail onychomycosis are safe and effective in producing mycological cure. What's already known about this topic? Topical treatments traditionally have lower success rates than oral treatments. Oral treatments have the advantage of shorter treatment durations, but also present challenges in cases of drug-drug interactions or immunosuppression. A network meta-analysis (NMA) gathers data from indirect evidence to gain confidence about all treatment comparisons and allows for estimation of comparative effects that have not been investigated in head-to-head randomized clinical trials (RCTs). What does this study add? This NMA of efficacy and safety includes all RCTs of oral, topical, combination and device-based treatments for toenail onychomycosis, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement for NMA. The odds of achieving mycological cure with continuous terbinafine 250 mg or continuous itraconazole 200 mg were significantly greater than topical treatments. Fluconazole, pulse regimens of terbinafine and itraconazole, and topical treatments did not differ significantly in the odds of achieving mycological cure.

Although labeling changes and market withdrawal have been implemented for oral ketoconazole (KTZ) due to serious adverse effects (AEs), topical KTZ is generally thought to be effective and safe for the treatment of superficial fungal infections. New dermatologic indications for the use of topical KTZ have arisen such as onychomycosis, blepharitis, and hair loss. This article aims to review the literature on topical KTZ's efficacy and AEs, as well as provide an overview on current insights regarding its mechanism of action and upcoming developments. A PubMed search was done to include randomized controlled trials (RCTs) focusing on the use of topical KTZ in human subjects. Forty studies with 4566 patients were included in this review. Topical KTZ is clinically effective for the treatment of -related conditions such as seborrheic dermatitis (SD) and pityriasis versicolor (PV) with a reported efficacy of 63-90% and 71-89%, respectively. Topical KTZ demonstrates high clinical efficacy for -related conditions. More efficacious alternatives are now available for and . Although topical KTZ is safe, clinicians should be aware that allergic contact dermatitis may occur. Further studies should be completed to investigate the use of topical KTZ for hair loss and inflammatory dermatoses.
