OBJECTIVES
Dermatomycoses, fungal diseases that affect the superficial layers of skin, hair or nails, are a public health concern due to their high prevalence. In Brazil, dermatomycoses are not notifiable diseases, so only fragmented epidemiological studies have been reported in the national literature. To evaluate the epidemiological profile of dermatomycoses in preschoolers and school children in Sinop, Mato Grosso (MT), Brazil.
METHODS
Classic methods were used to perform 782 mycological examinations to identify dermatophytosis, cutaneous candidosis and pityriasis versicolor in preschoolers and school children aged between 6 months and 12 years in 11 educational institutions in Sinop, MT.
RESULTS
Among the evaluated clinical specimens, 5.2% tested positive for dermatophytosis, with 58.45% of these cases corresponding to tinea capitis, followed by skin (tinea corporis and tinea pedis) and toenail (tinea unguium) lesions; zoophilic fungi predominated. Microsporum canis and Trichophyton mentagrophytes complex were isolated in 53.66% and 24.39% of the cases, respectively. Regarding cutaneous candidosis, 9.1% of the specimens tested positive for this disease, with 59.16% and 12.7% of the cases corresponding to toenails and interdigitoplantar lesions, respectively. Candida albicans caused 70.43% of the lesions. The remaining specimens (85.7%) tested positive for pityriasis versicolor; children aged between 6 and 12 were the most affected (71.79%).
CONCLUSION
Our results agree with most epidemiological studies carried out in Brazil and demonstrate the high frequency of mycoses in preschoolers and school children, a result of poor personal hygiene and favourable weather conditions in Northern Mato Grosso, Brazil.

The clinical and histological features of a dermomycosis caused by a new dematiaceum fungus are described. The mycological characteristics of this fungus individualize and differentiate it from other demiataceum hyphomycetes, proposing the name of Botryomyces caespitosus for it. The submicroscopic features are commented, as well.

BACKGROUND
Fungal skin infections are recognised as one of the most common health disorders globally, and dermatophyte infections of the skin, hair and nails are the most common fungal infections. Dermatophytes can be classified as anthropophilic, zoophilic or geophilic species based on their primary habitat association, and this classification makes epidemiological analysis useful for the prevention and control of these infections. The Irish contribution to the epidemiology of these infections has been scant, with just two papers (both reporting paediatric tinea capitis only) published in the last 20 years, and none in the last seven.
OBJECTIVES
To perform a comprehensive retrospective epidemiological analysis of all dermatological mycology tests performed in University Hospital Limerick over a 20-year period.
METHODS
All mycology laboratory test results were extracted from the Laboratory Information Management System (LIMS, iLab, DXC Technologies) from 2001 to 2020 inclusive for analysis. Specimen types were categorised according to the site of sampling. The data were analysed using Microsoft Excel.
RESULTS
About 12,951 specimens of skin, hair and nails were studied. Median patient age was 42 years (IQR 26-57) with a slight female preponderance (57.2%). Two thirds of samples (67%, n = 8633) were nail, 32% were skin scrapings (n = 4118) and 200 hair samples (1.5%) were received. Zoophilic dermatophytes were more commonly present in females (38% F, 23% M, proportion of dermatophytes) and in those under 10 years of age or from 45 to 70 years (36% and 34% zoophiles, respectively, proportion of dermatophytes), although anthropophiles predominated every age and gender category. Anthropophiles had their highest prevalence in the 10-20 years age category (80% anthropophiles, proportion of dermatophytes), and yeast infections were more prevalent in older patients (29% of >60 year olds vs. 17% of <60 year olds, proportion of all fungal positives). Trichophyton rubrum was the most prevalent pathogen detected, accounting for 53% of all dermatophytes detected, 61% of those detected from nail samples and 34% from skin and hair samples. Trichophyton tonsurans was the most prevalent dermatophyte in tinea capitis, accounting for 37% of dermatophytes detected. Both of these organisms are anthropophilic, and this group showed consistently increased prevalence in proportion to all fungal isolates. The proportion of this dermatophyte class (anthropophiles) increased among both nail samples and skin/hair samples during the study period, from 55% of samples in the first 5 years of the study (2001-2005) to 88% (proportion of dermatophytes) in the final 5 years. Conversely, yeast detection decreased.
CONCLUSIONS
This study provides a detailed overview of the epidemiology of the fungal cultures of skin, nail and hair samples in the Mid-West of Ireland over a 20-year period. Monitoring this changing landscape is important in identifying likely sources of infections, to identifying potential outbreaks, and may help guide empiric treatment. To the best of our knowledge, this study provides the first detailed analysis from Ireland of fungal detections from skin, hair and nail samples, and is the first epidemiological fungal report of any kind in over 7 years.
