| [tinea capitis]. | tinea capitis is a widespread scalp infection in children caused by dermatophytes. in fact, it is the most common cutaneous mycosis in children but is uncommon in adults. the disease has been major public health concern for decades. some factors implicated in infection include poor personal hygiene, crowded living conditions, and low socioeconomic status. it can be caused by any pathogenic dermatophyte except for epidermophyton floccosum and trichophyton concentricum. trichophyton rubrum, the mo ... | 2008 | 18346430 |
| terbinafine hydrochloride oral granules versus oral griseofulvin suspension in children with tinea capitis: results of two randomized, investigator-blinded, multicenter, international, controlled trials. | although griseofulvin is currently considered the primary antifungal agent used to treat tinea capitis in many countries, increasingly higher doses and longer durations of treatment are becoming necessary to achieve effective treatment. alternative antifungal therapies with shorter/simpler treatment regimens may be important to develop for this indication. | 2008 | 18378354 |
| molecular characterization of a squalene epoxidase gene in dermatophyte pathogen trichophyton tonsurans. | trichophyton tonsurans is one of the dermatophyte fungi which invades the skin and hair of human. several properties of this fungus have been investigated so far. however a few studies were carried out in the field of molecular biology of this fungus. in the present study, we tried to identify the squalene epoxidase gene which is related to synthesis of ergosterol in this fungus. | 2008 | 18392096 |
