“…However, in one class, where the highest number of infected children were taught, 12% were carriers. These figures indicate similar trends to those reported for tinea capitis in the USA where anthropophilic infections have become the dominant causes of infection with T. tonsurans as the main cause of disease in urban populations 8,9 . In the USA the reported prevalence rates are also over 3% 10 .…”

A survey of tinea capitis conducted under the auspices of the European Confederation of Medical Mycology showed that laboratories contributing to a voluntary scheme for reporting have recently been seeing a different pattern of scalp ringworm. The survey was conducted among 92 medical mycology laboratories across 19 European countries by postal questionnaire comparing the years 1987 with 1997. The survey shows an overall increase in the numbers of cases caused by anthropophilic infections, which, in 1997, were the dominant causes of scalp infection; the greatest increase was seen in laboratories covering urban populations and in African Caribbean children living in Europe. While the commonest infection remains Microsporum canis, the largest overall increase has been in Trichophyton tonsurans, which in 1997 was the second commonest cause of infection overall and the commonest in urban populations. The pattern of change is not uniform in Europe and while some cities have reported large increases in T. tonsurans others, e.g. in France, have seen more cases of infection due to T. soudanense and M. audouinii. While these figures do not necessarily reflect changes in the underlying prevalence of infection, the trends are important to recognize as the control measures for anthropophilic tinea capitis differ from those used in zoophilic infections. In particular there is a need for an increased level of surveillance and more advice on control given to primary care physicians, dermatologists and school health authorities.

A study of tinea capitis was carried out during October 1998, involving 8531 school children aged 6-14 years (4718 males and 3813 females), attending 12 primary schools located in urban, rural, and refugee camp communities in the Nablus district in the Palestinian Authority. A total of approximately 1389 of the school children aged 6-12 years (724 males and 665 females) were also surveyed on three occasions at 2-3 month intervals, over a 9-month period (October 1998-May 1999) using the hair brush technique, for prevalence of asymptomatic tinea capitis carriage. Twenty-three(0.27%) mycologically proven cases of tinea capitis were detected.

“…T. tonsurans is most commonly found in Central and Southern Europe, U.S.S.R. and Central and South America 24 . In the United States, the fungus predominates in scalp infections 23,25,54 . Infections in humans are often acquired from contact with animals, environment or person-to-person spread 24 .…”

SUMMARYDermatophytosis are superficial mycoses caused by fungi that can invade stratum corneum and keratinized tissues. In order to study the frequency of dermatophytes species and the clinical manifestations caused by these fungi, in São Paulo, SP, Brazil, the authors analyzed cultures isolated at the Mycology Laboratory from a selected population (15,300 out-patients of the Hospital das Clínicas, Department of Dermatology, Faculty of Medicine of University of São Paulo) from January 1992 to June 2002.The most prevalent dermatophyte was Trichophyton rubrum (48.7%), followed by Microsporum canis (20.9%), Trichophyton tonsurans (13.8%), Trichophyton mentagrophytes (9.7%), Epidermophyton floccosum (4.1%), and Microsporum gypseum (2.5%). These agents determined more than one clinical manifestation, i.e., tinea corporis (31.5%), tinea capitis (27.5%), tinea unguium (14.8%), tinea cruris (13.9%), tinea pedis (9.9%), and tinea manuum (1.9%). Clinical variants of dermatophytosis and their relationship to the etiologic agents were studied and the results were compared to those obtained in previous studies in other regions of Brazil and in other countries.
