| tinea capitis in the elderly. a report on two cases caused by trichophyton tonsurans. | the clinical picture in tinea capitis due to trichophyton tonsurans varies. in this report, 2 elderly female patients with t. tonsurans infections of the scalp mimicking eczema seborrhoeicum and discoid lupus erythematosus, respectively, are described. recurrence of the infection in the first case was probably related to reduced fungal sensitivity to griseofulvin, as indicated in in vitro studies. | 1984 | 6468723 |
| current status of the identification and management of tinea capitis. | tinea capitis due to trichophyton tonsurans has become a significant health problem affecting children and adolescents. this infection has several different distinctive clinical patterns which, if not recognized, may result in delayed diagnosis and therapy. this review is designed to emphasize the differences between tinea capitis caused by t tonsurans and that caused by other organisms. current diagnostic and therapeutic measures are discussed. | 1983 | 6634265 |

| dermatophytes identified at the australian national reference laboratory in medical mycology 1966-1982. | over a 17 yr period from 1966 to 1982, 4354 dermatophytes were identified at the australian national reference laboratory in medical mycology. the most frequently identified species was trichophyton rubrum, accounting for 35.3% of identifications, followed by trichophyton mentagrophytes (26.5%), trichophyton tonsurans (12.8%), epidermophyton floccosum (10.7%) and microsporum canis (8.4%). specimens taken from the feet were the most common source of the trichophyton rubrum isolates, followed by s ... | 1984 | 6379581 |
| ecology and epidemiology of dermatophyte infections. | our knowledge of ecology and epidemiology of dermatophytes and the factors influencing their transmission has helped us understand better the natural history of dermatophytoses. it seems that the anthropophilic agents of scalp infection are being eradicated in developing nations. the exception is trichophyton tonsurans-related tinea capitis in north america. microsporum canis is a prevalent agent of tinea capitis in many regions of the world, and this could be related to close association of hum ... | 1994 | 8077503 |
| tinea capitis: epidemiology, diagnosis, treatment, and control. | since the 1970s there has been a steady rise in the number of cases of tinea capitis in the united states, most of them caused by trichophyton tonsurans. although the infection is seen most frequently in black children, it can occur in white persons and can affect persons of all ages. control of tinea capitis is difficult for several reasons, including subtle clinical infection, asymptomatic carriage of fungus, fomite spread, and the need for weeks to months of oral medications. although griseof ... | 1994 | 8077507 |
| increasing importance of trichophyton tonsurans in childhood tinea in new south wales. the pattern of childhood tinea in new south wales, australia 1979-1988: the emergence of trichophyton tonsurans as an important pathogen in tinea capitis in white children. | a retrospective study was undertaken of 192 cases of culture proven tinea capitis occurring between 1979 and 1988 in a predominantly white population of children in new south wales (nsw). the aim of the study was to identify whether trichophyton tonsurans was increasing in importance in the causation of this condition in australia as it was in many other parts of the world. the results of our study were compared with those of earlier australian studies. our study demonstrated that trichophyton t ... | 1993 | 8240189 |

| an epidemic of tinea corporis caused by trichophyton tonsurans among wrestlers in sweden. | an epidemic of tinea corporis due to trichophyton tonsurans among wrestlers in sweden is described. totally 19 patients, 14 patients from malmö and 5 from gothenburg, were found. the suspected source of this epidemic was from a wrestlers' team from the usa visiting sweden in april, 1993. all patients were treated orally with either griseofulvin, fluconazole or terbinafine, and all were cured. to prevent spreading, epidemiological tracing of secondary cases is important. | 1995 | 8578955 |
| a u.s. epidemiologic survey of superficial fungal diseases. | large-scale studies performed outside the united states have demonstrated that most cases of onychomycosis and tinea pedis are caused by dermatophytes, primarily trichophyton rubrum. however, other studies have suggested that yeasts and nondermatophytic molds may play a role, particularly in onychomycosis. | 1996 | 8859279 |
| increased incidence of trichophyton tonsurans tinea capitis in ontario, canada between 1985 and 1996. | in canada, since the 1990s, trichophyton tonsurans has emerged as the main cause of tinea capitis. prior to this the more common agents were t. verrucosum, microsporum canis and m. audouinii. over the past few years the incidence of t. tonsurans has increased such that in 1985 and 1996 the cases of mycologically confirmed tinea capitis due to t. tonsurans were 9% and 76%, respectively. the epidemic of t. tonsurans has reduced the role of wood's lamp in diagnosis of tinea capitis. the age distrib ... | 1998 | 9776814 |
| 1998 william j. stickel bronze award. antifungal activity of melaleuca alternifolia (tea-tree) oil against various pathogenic organisms. | tea-tree oil (oil of melaleuca alternifolia) has recently received much attention as a natural remedy for bacterial and fungal infections of the skin and mucosa. as with most naturally occurring agents, claims of effectiveness have been only anecdotal; however, several published studies have recently demonstrated tea-tree oil's antibacterial activity. this study was conducted to determine the activity of tea-tree oil against 58 clinical isolates: candida albicans (n = 10), trichophyton rubrum (n ... | 1998 | 9791953 |
