Drug-based treatment of superficial fungal infections, such as onychomycosis, is not the only defense. Sanitization of footwear such as shoes, socks/stockings, and other textiles is integral to the prevention of recurrence and reduction of spread for superficial fungal mycoses. The goal of this review was to examine the available methods of sanitization for footwear and textiles against superficial fungal infections. A systematic literature search of various sanitization devices and methods that could be applied to footwear and textiles using PubMed, Scopus, and MEDLINE was performed. Fifty-four studies were found relevant to the different methodologies, devices, and techniques of sanitization as they pertain to superficial fungal infections of the feet. These included topics of basic sanitization, antifungal and antimicrobial materials, sanitization chemicals and powder, laundering, ultraviolet, ozone, nonthermal plasma, microwave radiation, essential oils, and natural plant extracts. In the management of onychomycosis, it is necessary to think beyond treatment of the nail, as infections enter through the skin. Those prone to onychomycosis should examine their environment, including surfaces, shoes, and socks, and ensure that proper sanitization is implemented.

Review
Sporotrichosis is a cosmopolitan subcutaneous mycosis caused by Sporothrix species. Recently, this mycosis has gained notoriety due to the appearance of new endemic areas, recognition of new pathogenic species, changes in epidemiology, occurrence of outbreaks, and increasing numbers of cases. The purpose of this study is to analyze the peculiarities of sporotrichosis cases in Brazil since its first report in the country until 2020. In this work, ecological, epidemiological, clinical, and laboratorial characteristics were compiled. A systematic review of human sporotrichosis diagnosed in Brazil and published up to December 2020 was performed on PubMed/MEDLINE, SciELO, Web of Science, and LILACS databases. Furthermore, animal sporotrichosis and environmental isolation of Sporothrix spp. in Brazil were also evaluated. The study included 230 papers, resulting in 10,400 human patients. Their ages ranged from 5 months to 92 years old and 55.98% were female. The lymphocutaneous form was predominant (56.14%), but systemic involvement was also notably reported (14.34%), especially in the lungs. Besides, hypersensitivity manifestations (4.55%) were described. Most patients had the diagnosis confirmed by isolation of Sporothrix spp., mainly from skin samples. Sporothrix brasiliensis was the major agent identified. HIV infection, cardiovascular diseases, and diabetes were the most common comorbidities. Cure rate was 85.83%. Concerning animal sporotrichosis, 8538 cases were reported, mostly in cats (90.77%). Moreover, 13 Sporothrix spp. environmental strains were reported. This review highlights the burden of the emergent zoonotic sporotrichosis in Brazil, reinforcing the importance of "One Health" based actions to help controlling this disease.

Review
Recalcitrant nail plate infections can be life-long problems because localizing antifungal agents into infected tissues is problematic. In this systematic review, guided by the SPIDER method, we extracted chemical nail permeation data for 38 compounds from 16 articles, and analyzed the data using quantitative structure-property relationships (QSPRs). Our analysis demonstrated that low-molecular weight was essential for effective nail penetration, with <120 g/mol being preferred. Interestingly, chemical polarity had little effect on nail penetration; therefore, small polar molecules, which effectively penetrate the nail, but not the skin, should be set as the most desirable target chemical property in new post-screen onychomycosis candidate selections.

INTRODUCTION
There are few studies focusing on ungual lesions in patients with lupus erythematosus (LE). The aim of this study is to describe the type and the prevalence of ungual lesions among LE patients.
PATIENTS AND METHODS
A systematic literature review with analysis of individual data was performed by searching the MEDLINE database for scientific articles using the keywords "lupus erythematosus" and "nail".
RESULTS
Two-hundred and eighty-seven cases were collated including 55.1% women, with an average age of 32.2±11 years. The most common ungual or peri-ungual lesions were longitudinal ridging (83 patients, 28.9%), peri-ungual erythema (62 patients, 21.6%), onycholysis (60 patients, 20.9%), melanonychia (34 patients, 11.8%) and dyschromia (33 patients, 11.5%). An association between the presence of onycholysis and peri-ungual erythema and disease activity was noted [respectively 33 (38.8%) and 26 (30.6%) patients out of 85 with active disease versus 3 (5.8%) and 4 (7.7%) patients out of 52 with non-active disease, P<0.001 and P=0.018]. Screening for fungal infection was performed in one third of the cases, with proven onychomycosis in 34.7% of cases.
DISCUSSION
Ungual lesions are not specific and do not permit diagnosis of LE. They can in fact occur in other diseases such as connective tissue disorders. However, their diagnosis is important because they may be the presenting sign in LE, and certain of them may be associated with more active disease. Onychomycosis is frequently a confounding factor in such immunocompromised patients.

Meta-Analysis
BACKGROUND
Tinea capitis accounts for25 to 30% of all fungal infections, but it is often ignored because it is not life threatening in nature. It is more common among schoolchildren particularly in developing countries. Due to the presence of significant variability among the previous studies, this study was conducted to provide a pooled prevalence and associated factors of tinea capitis in Ethiopian schoolchildren.
METHOD
We conducted a systematic search in five major databases for articles similar to our topic. This review included school-based cross-sectional studies that were reported in English and conducted from 2006 through 2022. The data were extracted using Microsoft Excel and further analysis was done using StataTM Version 17.0 statistical software. Forest plots were used to assess the presence of heterogeneity with 95% confidence intervals. A random effects meta- analysis model was used to pool primary estimates. To declare the presence or absence of association, 95% confidence interval with odds ratio was used.
RESULTS
Fourteen studies with a total of 9465 schoolchildren were included. The pooled prevalence was 29.03% (95%CI: 15.37-42.71). There was observed heterogeneity, which could be explained by publication bias (P = 0.04). Family history of tinea capitis (OR: 9.18, 95%CI: 3.5-24.02), under the age of 10 years (OR: 1.65, 95%CI: 1.17-2.33) were factors increasing the development of tinea capitis among schoolchildren and schoolchildren who had hair wash at least once a week (OR: 0.31, 95%CI: 0.24-0.42) was significantly associated with reduced risk for tinea capitis.
CONCLUSION
One of the most prevalent childhood health condition in Ethiopia is tinea capitis, which affects over one in every four schoolchildren. Schoolchildren who had family history of tinea capitis and under the age of 10 years were the identified risk factors but they had hair wash at least once a week was the protective factor of tinea capitis among schoolchildren. Clinical and public engagement activities are needed to overcome the burden of the disease.

Review
INTRODUCTION
Sporotrichosis is a subcutaneous mycosis caused by fungi of the genus sp. Phenotypic and genotypic differences have been associated with their geographic distribution, virulence, or clinical manifestation of sporotrichosis. In the past decade, the interest in identifying species of the sp. has been increasing, due to its epidemiological importance and, in consequence, is important to know how to preserve them for future studies, in culture collection.
AIMS
The purposes of this study were to analyze the global distribution of environmental isolates and/or causal agents of sporotrichosis identified by polyphasic taxonomy, with mandatory use of molecular identification, and to evaluate the percentages and distribution of isolates stored in culture collections.
METHODS
A systematic review of articles on animal and human sporotrichosis and/or environmental isolation of the fungus, from 2007 to 2023, was done. Results: Our results demonstrated that, , , and were the most identified species. With respect to the deposit and maintenance of species, we observed that only 17% of the strains of sp. isolated in the world are preserved in a culture collection.
CONCLUSIONS
This systematic review confirmed a difficulty in obtaining the frequency of species stored in culture collection and insufficient data on the molecular identification mainly of animal sporotrichosis and isolation of sp. in environmental samples.

BACKGROUND
Onychomycosis is the most common nail disorder, often causing physical, emotional, and aesthetic consequences. The effect of both the condition itself and treatment on quality of life has not been well studied.
OBJECTIVE
The objectives of this study were to systematically review the available literature describing the effect of onychomycosis and treatment on quality of life.
METHODS
We performed a search of the onychomycosis literature published before April 13, 2020. Articles were included in the review if primary data were presented, patient-reported outcome measures were used, and onychomycosis was specifically examined.
RESULTS
Thirty studies were included in the final analysis. Poorest quality-of-life scores were associated with women and fingernail involvement. Quality-of-life scores improved from baseline with all treatment types; there were greater improvements reported with oral treatments compared with topical ones.
CONCLUSIONS
This review affirms that onychomycosis significantly influences quality of life, warranting effective treatment. All treatments resulted in quality-of-life improvements; however, studies on oral and topical therapies were of higher quality than those evaluating devices. Increased efforts are needed to understand the effect of the disease and therapy as assessed by validated, nail-specific outcome measures that accurately assess patients' cosmetic, physical, and social difficulties.

Review
The Caatinga is an exclusively Brazilian biome where semiarid climatic conditions promote singularities in adaptive biodiversity. Many aromatic species are found in this region possessing antifungal properties, which are attributed to their essential oils. Thus, we questioned whether essential plant oils found in the Caatinga present anti-dermatophytic potential. Dermatophytes are keratinophilic fungi that cause one of the most prevalent mycoses globally, skin infections known as dermatophytoses (tineas). Here, we provide a comprehensive report of the available published information, analyzing the methods used to evaluate the antifungal activity, verifying the quality of the evidence and possible clinical applications, and discussing research trends in this area. The plants studied concentrated in the genera Croton (Euphorbiaceae), Lippia (Verbenaceae), Piper (Piperaceae), and Mentha (Lamiaceae). All of the studies used in vitro tests to analyze antifungal potential, and little evidence was ascertained concerning the mechanism of antifungal action. In addition, the essential oils also evidenced drug modifying activity of conventional antifungal drugs (Ketoconazole and Terbinafine). We believe that the anti-dermatophyte potential of plant essential oils occurring within the Caatinga is underestimated and that this review will encourage future chemical-pharmacological investigations into the plants within this biome.Key points• The essential oils from plants occurring in the Caatinga Biome present unknown anti-dermatophyte potential.• The studies against dermatophyte fungi concentrate on the families Lamiaceae and Verbenaceae.• In vitro assays were used to assess the anti-dermatophyte potential of the essential oils.

Meta-Analysis
Published case fatality in blastomycosis patients ranges between 4% and 78%. This study aimed to assess mortality associated with blastomycosis and identify its associated risk factors. We conducted a systematic review of publications related to Blastomyces dermatitidis available in PubMed and Scopus databases. Studies that reported data on blastomycosis mortality and that were published from inception through February 2018 were assessed and included in the analysis. Using the R meta package, a random-effect model meta-analysis was used to calculate pooled and stratified estimates of case-fatality proportions and risk ratios. Of 1553 publications, we included 20 studies reporting on a total of 2820 cases of blastomycosis between 1970 and 2014 and three case series reports with 10, 21, and 36 patients. The mean or median ages ranged from 28 to 59 years. Mortality was defined as attributable mortality caused by blastomycosis in 13 studies. Among 14 studies with a standard error ≤0.05, the overall pooled mortality was 6.6% (95% confidence interval [CI], 4.9-8.2) with 57% heterogeneity. The mortality rate was 37% (95% CI, 23-51) in immunocompromised patients and 75% (95% CI, 53-96) in patients who developed an acute respiratory distress syndrome (ARDS) (n = 3 studies each). ARDS was the only identified risk factor in general patients (risk ratio = 10.2). The overall mortality was significantly higher in studies involving immunocompromised patients and ARDS patients. Our analysis showed considerable heterogeneity among studies. Inconsistent mortality definitions may have contributed to the observed heterogeneity. Further research is needed to assess potential risk factors for mortality.

Meta-Analysis
AIM
Toenail fungal infections account for half of all nail disease cases, and a highly negative impact on patient quality of life. Our aim was to compare the efficacy and safety of commercially available oral antifungals for onychomycosis.
METHODS
A systematic review was performed in PubMed and Scopus. Randomized controlled trials evaluating the effect of oral antifungals on mycological cure, discontinuation and adverse events were included. Network meta-analyses were built for each outcome. Results were reported as odds ratios (OR) with 95% credibility intervals (CrI). Ranking probabilities were calculated by surface under the cumulative ranking analysis (SUCRA).
RESULTS
We included 40 trials ( = 9568). Albaconazole 400 mg (OR 0.02 [95% CrI 0.01-0.07] placebo), followed by posaconazole 200-400 mg and terbinafine 250-350 mg were considered the best therapies (SUCRA probabilities over 75%). For the networks of discontinuation and individual adverse events, few significant differences among treatments were observed, but itraconazole 400 mg was considered the safest drug (SUCRA around 25%). Albaconazole 400 mg, posaconazole 200-400 mg, and terbinafine 250-350 mg were the most effective therapies for onychomycosis, while itraconazole 400 mg was the safest.
CONCLUSION
The profile of albaconazole and posaconazole compared to current first-line therapies should be further investigated in well-designed trials.
