Tinea capitis among children at one suburban primary school in the City of Maputo, Mozambique

Abstract

RESUMO O estudo avaliou a prevalência da Tinea capitis na população estudantil duma Escola Primária e também identificou os agentes causais responsáveis. Escamas do couro cabeludo foram recolhidas das crianças apresentando sinais clínicos sugestivos de Tinea capitis. Dermatófitos foram identificados seguindo procedimentos micológicos padronizados. Este estudo encontrou uma prevalência clínica de Tinea capitis de 9,6% (110/1149). Os dermatófitos isolados foram Microsporum audouinii, Trichophyton violaceum e Trichophyton mentagrophytes. O agente causal mais prevalente neste estudo foi Microsporum audouinii confirmando os achados dos estudos transversais anteriores levados a cabo na cidade de Maputo.Palavras-chaves: Tinea capitis.

Tinea capitis in the pediatric population: A study from North India

“…Sidat et al had reported the isolation of multiple isolates from a single specimen. [15] Interestingly, none of our samples showed growth of more than one fungal species, as may have been expected from morphology or KOH examination. We failed to isolate any cases with T. schoenlenii, unlike previous studies from similar geographical areas.…”

“…Earlier reports have shown a positive isolation rate of 56-92%. [10,15] The predominant species seen by us was T. violaceum (responsible in almost 88.6% of all the culture-positive cases). This could be because our catchment area was a densely populated area, allowing close contact between children.…”

“…The other type included children presenting initially with GPTC morphology, but who went on to develop pustules in a widespread distribution over the scalp within 1 week of starting treatment. Although previous studies have described isolation of multiple dermatophyte species from a single patient, [15] the coexistence of more than one morphological type of TC in a single child has only rarely been reported. [16] Examination of KOH-stained smears microscopically revealed different patterns of distribution of spores in the hair shaft.…”

A study of skin disease spectrum occurring in Angola phototype V–VI population in Luanda

“…In Western and Central Africa, Trichophyton soudanense and Microsporum audouinii are the main anthropophilic species of TC. On the other hand, Trichophyton rubrum , Trichophyton mentagrophytes, and Tricholosporum violaceum are the most frequent causal agents of non‐TC dermatophytosis . Nevertheless, no recent studies about the prevalence of current fungal species are available in Angola.…”

A study on tinea capitis in the pre school and school going children

“…It was observed that T. violaceum was main isolate from black dot type while T. mentagrophyte was the main isolate from grey patch and kerion lesions. TC is a common fungal infection, particularly among children in urban regions [8][9][10]. More often than not, it presents with mild scaling and little hair loss, which is reversible.…”
