tinea capitis

Lidia García-Agudo, Jorge J Espinosa-Ruiz
Tinea capitis is considered the most frequent dermatophyte infection in children. The etiological agents vary from time to time and by geographical area, although they normally are zoophilic dermatophytes and in the last years also anthropophilic species. We report a clinical case of inflammatory tinea capitis in a 6-year-old child caused by Microsporum gypseum, a geophilic fungus pathogenic to humans and animals. The sources of human infection are soil, cats, dogs and small mammals. This species is less frequent as a cause of dermatophytosis in humans, described mainly in tinea corporis and rarely in tinea capitis...

Because of the limited access to more powerful diagnostic tools, there is a paucity of data regarding the burden of fungal infections in Burkina Faso. The aim of this study was to estimate the incidence and prevalence of serious fungal infections in this sub-Saharan country. We primarily used the national demographic data and performed a PubMed search to retrieve all published papers on fungal infections from Burkina Faso and its surrounding West African countries. Considering the prevalence of HIV infection (0...

Our work aimed to generate a preliminary estimation of severe and chronic fungal diseases in the Republic of Kazakhstan with a model proposed by LIFE (Leading International Fungal Education). Calculations were carried out on data from 2015. Published results of studies of mycoses in Kazakhstan were identified; in the absence of national data from the scientific literature, the frequency of life-threatening and serious mycoses in defined groups of patients at risk from other countries were taken into account...

Trichophyton tonsurans, a major pathogen of tinea capitis and tinea corporis, has been isolated from players of contact sports in Japan. To understand the contemporary epidemic in Japan, the molecular types of 208 strains isolated between 2011 and 2015 were determined. Of these, 142 were isolated from practitioners of judo, 28 from wrestlers, seven from sumo wrestlers, and 31 from individuals with unknown backgrounds. Based on length polymorphisms of the non-transcribed spacer (NTS) region of the ribosomal RNA gene, these 208 strains could be divided into three subtypes, NTS I(204; 98...

Although tinea capitis is the most common fungal infection in children, significant changes have been reported in its epidemiology worldwide, as a result from certain geographic, climatic and cultural differences in one hand, as well as the changes in its etiologic pattern. The clinical manifestation of the infection and the stage of inflammation vary from mild desquamation to severe suppurative indurated plaques in kerion - like the pattern, depending on the nature of the etiologic agent and the host-immune response...

Nontargeted late effects of radiation include an increased risk of cardiovascular disease, although this is still debatable in the context of low-dose radiation. Tinea capitis patients treated in childhood with X rays to induce scalp epilation received a low dose of radiation to their carotids. To better clarify this issue, we evaluated carotid atherosclerosis in a cohort of such patients treated in 1950-1963 in Portugal. A group of 454 individuals randomly chosen from previously observed Portuguese tinea capitis patients and a control group mainly composed of their spouses (n = 280) were enrolled...

With the increasing number of immunocompromised hosts, the epidemiological characteristics of fungal infections have undergone enormous changes worldwide, including in China. In this paper, we reviewed the existing data on mycosis across China to summarize available epidemiological profiles. We found that the general incidence of superficial fungal infections in China has been stable, but the incidence of tinea capitis has decreased and the transmission route has changed. By contrast, the overall incidence of invasive fungal infections has continued to rise...

Fungal infections caused by dermatophytes recently became more common. Available antifungal drugs are limited because of emergence of resistant strains due to prophylaxis with them, so there is an urgent need for novel antifungals. This study is aimed to detect the antifungal activity of silver nanoparticles (SNPs) on Fluconazole resistant dermatophytes isolated from primary school children clinically suffering from tinea capitis and attending El-Sheikh Zaid Dermatology Center in Ismailia. The study was done on 112 clinical cases...
