Review
New therapies for onychomycosis continue to be developed, yet treatments are seldom directly compared in randomized controlled trials. The objective of this study was to compare the rates of mycological cure for oral and topical onychomycosis treatments using network meta-analysis. A systematic review of the literature on onychomycosis treatments published before March 25, 2013, was performed, and data were analyzed using network meta-analysis. Terbinafine, 250 mg, therapy was significantly superior to all treatments except itraconazole, 400 mg, pulse therapy; itraconazole, 200 mg, therapy was significantly superior to fluconazole and the topical treatments; and fluconazole, efinaconazole, ciclopirox, terbinafine nail solution, and amorolfine treatments were significantly superior to only placebo. These results support the superiority of 12-week continuous terbinafine, 250 mg, therapy and itraconazole, 400 mg, pulse therapy (1 week per month for 3 months) while suggesting the equivalence of topical therapies. These results reflect findings from the literature and treatment efficacy observed in clinical practice.

Meta-Analysis Review
Nonpurulent cellulitis is an acute bacterial infection of the dermal and subdermal tissues that is not associated with purulent drainage, discharge or abscess. The objectives of this systematic review and meta-analysis were to identify and appraise all controlled observational studies that have examined risk factors for the development of nonpurulent cellulitis of the leg (NPLC). A systematic literature search of electronic databases and grey literature sources was performed in July 2015. The Newcastle-Ottawa Scale (NOS) was used to assess methodological quality of included studies. Of 3059 potentially eligible studies retrieved and screened, six case-control studies were included. An increased risk of developing NPLC was associated with previous cellulitis [odds ratio (OR) 40·3, 95% confidence interval (CI) 22·6-72·0], wound (OR 19·1, 95% CI 9·1-40·0), current leg ulcers (OR 13·7, 95% CI 7·9-23·6), lymphoedema/chronic leg oedema (OR 6·8, 95% CI 3·5-13·3), excoriating skin diseases (OR 4·4, 95% CI 2·7-7·1), tinea pedis (OR 3·2, 95% CI 1·9-5·3) and body mass index > 30 kg m (OR 2·4, 95% CI 1·4-4·0). Diabetes, smoking and alcohol consumption were not associated with NPLC. Although diabetics may have been underrepresented in the included studies, local risk factors appear to play a more significant role in the development of NPLC than do systemic risk factors. Clinicians should consider the treatment of modifiable risk factors including leg oedema, wounds, ulcers, areas of skin breakdown and toe-web intertrigo while administering antibiotic treatment for NPLC.

Review
INTRODUCTION
Fungal infections are reported to cause 23% of foot diseases and 50% of nail conditions in people seen by dermatologists, but are less common in the general population, affecting 3-5% of people.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of oral treatments for fungal toenail infections? What are the effects of topical treatments for fungal toenail infections? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2008 (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 11 systematic reviews, RCTs, or observational 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: amorolfine, butenafine, ciclopirox, fluconazole, griseofulvin, itraconazole, ketoconazole, mechanical debridement, terbinafine, and tioconazole.

INTRODUCTION
Onychomycosis is a common fungal infection of the nail. Laser and topical antifungal agent combination therapy is an emerging treatment for onychomycosis. The objective of this study was to systematically evaluate the efficacy and safety of laser and topical antifungal agent combination therapy for onychomycosis.
METHODS
The PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang and VIP databases were searched from inception to November 2021. Randomised controlled trials (RCTs) on laser therapy combined with topical antifungal agents for onychomycosis were included. The Cochrane Collaboration tool was used to assess the risk of bias, and Revman 5.3 software was used in the meta-analysis.
RESULTS
Twelve studies involving 869 patients were included in this meta-analysis. The results showed that compared with topical antifungal agents alone, laser and topical antifungal agent combination therapy was superior in terms of the complete cure rate (RR 6.04,95% CI (2.17, 16.85), P = 0.0006), mycological cure rate (RR 1.27, 95% CI (1.10, 1.48), P = 0.001), clinical effective rate (RR 1.38, 95% CI (1.20, 1.57), P < 0.00001) and patient satisfaction rate (RR 1.47,95% CI (1.17, 1.84), P = 0.0009).The subgroup analysis of outcome indicators, including mycological cure rate and clinical effective rate, demonstrated that both carbon dioxide (CO) laser therapy combined with topical antifungal therapy and 1064-nm neodymium-doped:yttrium aluminium garnet (Nd:YAG) laser therapy combined with topical antifungal therapy showed better results than topical antifungal therapy alone. No adverse events were identified except for three studies reporting transient burning sensation without treatment and mild to moderate pain, both of which were well tolerated.
CONCLUSION
The present study indicated that laser and topical antifungal agent combination therapy is effective for onychomycosis. However, more large-scale and well-designed RCTs are warranted.

Review
BACKGROUND
Onychomycosis is the most common nail disease seen in clinical practice. Inclusion of diverse groups in onychomycosis clinical trials subjects is necessary to generalise efficacy data.
OBJECTIVES
We aimed to systematically review race and ethnicity reporting and representation, as well as, treatment outcomes in onychomycosis clinical trials.
METHODS
A PubMed search for onychomycosis clinical trials was performed in August 2020. Primary clinical trial data were included and post hoc analyses were excluded. Categorical variables were compared using chi-squared and Fisher's exact tests. Statistical significance was set at p < .05. Photos in articles were categorised by Fitzpatrick skin type.
RESULTS
Only 32/182 (17.5%) trials reported on race and/or ethnicity and only one trial compared treatment efficacy in different subgroups. Darker skin colours were infrequently depicted in articles. Topical treatment, location with ≥1 US-based site, industry funding type and publication date after 2000 were significantly associated with reporting of racial/ethnic data (p < .05 for all comparisons).
LIMITATIONS
Demographics on excluded subjects and methods of recruitment were not available. Assigning Fitzpatrick skin type is inherently subjective.
CONCLUSIONS
This study highlights a need for consistent reporting of races and ethnicities of onychomycosis clinical trial participants with subgroup analyses of treatment efficacies.

Meta-Analysis Review
The purpose of this study is to evaluate the effectiveness and safety of photodynamic therapy (PDT) in treating superficial fungal infections, and provide reference for clinical application. In accordance with Population, Intervention, Comparator, and Outcome (PICO), the research question and keywords were formulated. Records published in English by PubMed, Embase, Cochrane Library, and Web of Science as of November 14, 2022 were retrieved, including the keywords "mycoses," "tinea," "photochemotherapy," etc. Besides, meta-analysis performed by STATA and PROSPERO registration code was CRD42022363448. One thousand four hundred eighty-four records were identified and 18 articles involving 343 patients with superficial fungal infections were enrolled. The overall mycological cure rate of PDT is 55% [95% confidence interval (CI): 0.46-0.65]. The fungal cure rate using methylene blue (MB) as photosensitizer (PS) is 67% (95% CI: 0.55-0.79); using 5-aminolevulinic acid is 34% (95% CI: 0.21-0.47); and using methyl aminolevulinate is 56% (95% CI: 0.33-0.78). The fungal cure rate of moderate-to-severe onychomycosis according to Onychomycosis Severity Index is 60% (95% CI: 0.47-0.73) and that of moderate onychomycosis is 66% (95% CI: 0.56-0.76). It was observed that the treatment parameters did not follow the same standard across studies. The majority of the included studies were moderate to low biased. PDT, particularly using MB as PS, has a certain mycological cure rate and safety at treating superficial mycoses. Due to the insufficient number of studies on PDT in the treatment of superficial fungal infections and the small sample size of some studies, more studies with standardized PDT parameters, large sample size, and long follow-up periods are needed to prove that PDT has the potential to become an alternative to traditional antifungal therapy or to find a better combination between them.

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.

Review
BACKGROUND
Extensive or recurrent tinea versicolor (TV) can be treated with systemic antifungal therapies, but no dosing regimens have been approved for this indication.
OBJECTIVE
To provide evidence-based recommendations for dosing regimens.
METHODS
A systematic literature search was performed to identify trials reporting mycologic cure. All trials were included and assessed for quality. Correlation and statistical analyses were used to evaluate the effects of different dosing regimen parameters on efficacy.
RESULTS
Fifty-seven trials investigating itraconazole, ketoconazole, fluconazole, and pramiconazole were included. Cumulative dose, treatment duration, and daily/weekly concentrations were shown to significantly influence mycologic cure rates for ketoconazole and pramiconazole but not for itraconazole and fluconazole.
CONCLUSION
Based on the efficacy evidence and potential safety concerns, this review supports the following dosing regimens: 200 mg/d for 5 or 7 days of itraconazole, 300 mg/wk for 2 weeks of fluconazole, and 200 mg/d for 2 days of pramiconazole.

BACKGROUND
Chromoblastomycosis (CBM), represents one of the primary implantation mycoses caused by melanized fungi widely found in nature. It is characterized as a Neglected Tropical Disease (NTD) and mainly affects populations living in poverty with significant morbidity, including stigma and discrimination.
METHODS AND FINDINGS
In order to estimate the global burden of CBM, we retrospectively reviewed the published literature from 1914 to 2020. Over the 106-year period, a total of 7,740 patients with CBM were identified on all continents except Antarctica. Most of the cases were reported from South America (2,619 cases), followed by Africa (1,875 cases), Central America and Mexico (1,628 cases), Asia (1,390 cases), Oceania (168 cases), Europe (35 cases), and USA and Canada (25 cases). We described 4,022 (81.7%) male and 896 (18.3%) female patients, with the median age of 52.5 years. The average time between the onset of the first lesion and CBM diagnosis was 9.2 years (range between 1 month to 50 years). The main sites involved were the lower limbs (56.7%), followed by the upper limbs (19.9%), head and neck (2.9%), and trunk (2.4%). Itching and pain were reported by 21.5% and 11%, respectively. Malignant transformation was described in 22 cases. A total of 3,817 fungal isolates were cultured, being 3,089 (80.9%) Fonsecaea spp., 552 (14.5%) Cladophialophora spp., and 56 Phialophora spp. (1.5%).
CONCLUSIONS AND SIGNIFICANCE
This review represents our current knowledge on the burden of CBM world-wide. The global incidence remains unclear and local epidemiological studies are required to improve these data, especially in Africa, Asia, and Latin America. The recognition of CBM as NTD emphasizes the need for public health efforts to promote support for all local governments interested in developing specific policies and actions for preventing, diagnosing and assisting patients.

Meta-Analysis Review
Mycetoma is a chronic infectious disease of the subcutaneous tissue with a high morbidity. This disease has been reported from countries between 30°N and 15°S since 1840 but the exact burden of disease is not known. It is currently unknown what the incidence, prevalence and the number of reported cases per year per country is. In order to estimate what the global burden of mycetoma is, a meta-analysis was performed. In total 50 studies were included, which resulted in a total of 8763 mycetoma cases. Most cases were found in men between 11 and 40 years of age. The foot was most commonly affected. Most cases were reported from Mexico, Sudan and India. Madurella mycetomatis was the most prevalent causative agent world-wide, followed by Actinomadura madurae, Streptomyces somaliensis, Actinomadura pelletieri, Nocardia brasiliensis and Nocardia asteroides. Although this study represents a first indication of the global burden on mycetoma, the actual burden is probably much higher. In this study only cases reported to literature could be used and most of these cases were found by searching archives from a single hospital in a single city of that country. By erecting (inter)national surveillance programs a more accurate estimation of the global burden on mycetoma can be obtained.
