Micoses superficiais na cidade de Manaus, AM, entre março e novembro/2003

Abstract

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

Aspectos clínicos de pacientes com pitiríase versicolor atendidos em um centro de referência em dermatologia tropical na cidade de Manaus (AM), Brasil

“…Several works in the literature studied pityriasis versicolor in relation to gender. Many studies show higher prevalence in male subjects, [10][11][12][13] while in other studies female patients were more affected. Apparently, there is no predominance between genders.…”

In vitro susceptibility testing of dermatophytes isolated in Goiania, Brazil, against five antifungal agents by broth microdilution method

“…Trychophyton rubrum, T. mentagrophytes and Microsporum canis are the most common species isolated in Brazil as causative agents of dermatophytosis 1,6,7,8,21 . In Goiania city, Brazil, these same etiological agents have been recovered in studies of COSTA et al 6,7 .…”

Micoses superficiais na Paraíba: análise comparativa e revisão literária

“…Women were more affected by the mycoses studied corroborating further studies. 4,9 There was a greater number of positive diagnosis for Pityriasis -27,92% (55 cases). From this total number, 63,64% (35 cases) are female patients and 36,36% (20 cases) are male patients.…”

“…Some family diseases facilitate the clinical development of mycosis, due to deficiency of the immune system, such as in diabetes, HIV and depression. The use of some drugs such as immunosuppressants and antibiotics 1,3,4 also facilitates the developmen of them. The main superficial mycoses in men are: Piedra negra (Piedrae hortae), Piedra branca (Trichosporon sp.…”

“…This fact shows the need to carry out periodic surveys to know exactly the frequency of the diseases and its etiologic agents, considering socioeconomic, geographic and climatic factors as a preventive epidemiological measure. 1,4 Piedra negra (Piedraia hortae)…”
