“…The seasons of the year did not influence the incidence of superficial mycoses. also reported in other studies carried out in the cities of Fortaleza, Goiania and Rio de Janeiro, 13,14,25,26 confir -ming that this is the most frequent mycosis in children. The high incidence of tinea capitis in children is due to the fact that children are more exposed to risk factors, such as poor hygiene, and crowded schools and daycare centers.…”

“…[10][11][12] The abusive use of antibiotic, cytostatic drugs and narcotics, as well as immunosuppressive diseases are some factors associated with the raising incidence of superficial mycoses in the last decades. 13,14 Since notification of mycoses is not mandatory, the exact extension of the problem in the Amazon region is unknown. Thus, as a measure of epidemiologic prevention it is important to perform periodical surveys on the frequency of mycoses and their etiological agents in respect to socioeconomic, geographic and climate factors.…”

BACKGROUND -Restricted superficial mycoses are fungal infections that appear on the skin superficial layers and their adnexa. However skin superficial mycoses represented by dermatophytoses and candidiasis can invade the corneal layer. This type of mycosis has a high incidence in the Amazon region. OBJECTIVES -To study the restricted superficial mycoses under the epidemiological and mycological point of view. PATIENTS AND METHODS -Patients presenting clinical suspicion of superficial mycoses submitted to mycological examination from March to November 2003 at the Clinical Mycology Laboratory/CPCS-INPA. RESULTS -Three hundred and ninety-four examinations were carried out throughout the period and 256 were positive. The mycoses with higher incidence were onychomycosis (135) and pityriasis versicolor (98). The most often isolated agents were Malassezia spp. (77) and Candida spp. (72). Tinea capitis was more frequent in pre-school children (3) and onychomycosis in adults (94). Mycoses were more prevalent in women (91). All socioeconomic classes were affected, with a predominance in class C (37). CONCLUSION -Onychomycosis and pityriasis versicolor affected mostly adults and Tinea capitis occured mainly in children. Superficial mycoses were more predominant in women. Malassezia spp. and Candida spp. were the most often isolated agents. Keywords: Fungi; Incidence; Mycoses Resumo: FUNDAMENTOS -Micoses superficiais estritas são infecções fúngicas que se localizam nas camadas superficiais da pele e seus anexos. As micoses superficiais cutâneas representadas pelas dermatofitoses e candidíases podem ultrapassar a camada córnea da pele. Na região amazônica possuem incidência elevada. OBJETIVOS -Estudar as micoses superficiais, estritas e cutâneas, diagnosticadas sob o ponto de vista epidemiológico e micológico. PACIENTES E MÉTODOS -Pacientes com suspeita clínica de micoses superficiais submetidos a exame micológico no período de março a novembro de 2003 no Laboratório de Micologia Médica/CPCS/INPA. RESULTADOS -Foram realizados 394 exames, tendo 256 apresentado diagnóstico positivo. As micoses mais incidentes foram onicomicoses (135) e pitiríase versicolor (98). Malassezia spp. (77) e Candida spp. (72) foram os agentes fúngicos mais isolados. Tinea capitis apresentou maior ocorrência nos pré-escolares (3), e onicomicoses em adultos (94). O sexo feminino foi o mais acometido (91). Todas as classes sociais foram infectadas, com predominância da C (37

“…This may be related to sudden hormonal changes; decrease of triglycerides in sebum (substances that would have antifungal action) during menopause [22]; and the fact that women are more concerned with their aesthetic appearance, regardless of age, and seek more dermatological assistance than men. This may have increased the median women's age.…”

Introduction: Dermatophytoses are considered a public health problem. The objectives of this study were to determine the evolution of their prevalence in the metropolitan area of Porto Alegre, Brazil, and to analyze the dermatophyte species distribution according to body site and demographic characteristics of the patients. Methodology: This work was a retrospective analysis of data from patients attending a tertiary care hospital during 1996-2011. Results: There were 9,048 cases with cultures positive for dermatophytes. Trichophyton rubrum occurred in 59.6% of the cases, followed by Trichophyton interdigitale (34%), Microsporum canis (2.6%), Epidermophyton floccosum (1.5%), Microsporum gypseum (1.3%), and Trichophyton tonsurans (0.9%). The angular coefficients for T. interdigitale, E. floccosum, T. rubrum, and M. canis were +1.119, +0.211, -0.826 and -0.324% per year, respectively. Males presented higher prevalence of infection (79.3% versus 53.9%). Tinea unguium occurred in 48.5% of the cases, followed by tinea pedis (33.1%). T. rubrum was the predominant species in all regions of the body except the scalp, where M. canis was responsible for 75% of the cases. Conclusion: Monitoring of the evolution of dermatophytosis tracks changes in prevalence over the years and may assist practical measures for the public health control of this disease.

Tinea capitis in a dermatology center in the city of Fortaleza, Brazil: the role of Trichophyton tonsurans

Abstract: Our data show that T. tonsurans is the main etiologic agent of tinea capitis, and is more likely to be found in females and in the prepubertal population.
