1/20. Acute infection with trichophyton rubrum associated with flares of atopic dermatitis.trichophyton rubrum has been implicated as a potential trigger in flares of atopic dermatitis. We describe a patient with atopic dermatitis who presented with a history of multiple flares and concurrent acute tinea pedis and onychomycosis. Symptoms of atopic dermatitis and culture-positive acute infection with T. rubrum resolved during each flare using systemic antifungals. Flares of atopic dermatitis may be triggered by acute T. rubrum infections. Antifungal therapy should be considered in these patients.- - - - - - - - - - ranking = 1keywords = tinea (Clic here for more details about this article) |
2/20. asthma induced by allergy to trichophyton rubrum.The worldwide incidence of asthma and of allergic respiratory diseases is increasing (Akiyama K. 'Environmental allergens and allergic diseases.' Rinsho Byori 1997;45(1):13. D'Amato G, Liccardi G, D'Amato M. environment and development of respiratory allergy. II. Indoors. Monaldi Arch Chest Dis 1994;49(5):412. Weeke AR. epidemiology of allergic diseases in children. Rhinol Suppl 1992;13:5. Ulrik CS, Backer V, Hesse B, Dirksen A. risk factors for development of asthma in children and adolescents: findings from a longitudinal population study. Respir Med 1996;90(10):623.) This has been attributed to several factors, including lifestyle changes and an expanding variety of potential causative allergens. Management of asthma entails preventive and acute medications, immunologic therapies, and removal of the identified allergen(s) from the patient's environment. Without the latter, patients may not experience full symptomatic relief. This case report describes a patient who developed bronchial asthma subsequent to an infection of tinea pedis and pedal onychomycosis; antifungal management resulted in full resolution of his tinea pedis, onychomycosis and asthma.- - - - - - - - - - ranking = 2keywords = tinea (Clic here for more details about this article) |
3/20. Case Report. tinea pedis and onychomycosis in primary school children in turkey.A cross-sectional study was performed in two primary schools with different socioeconomic status in the suburban and central areas of Manisa, turkey, in order to determine the prevalence of tinea pedis and onychomycosis. A full dermatological examination and a questionnaire on socioeconomic conditions were performed in a group of 785 randomly selected children aged 6-14. Of 9 clinically suspected tinea pedis and 4 onychomycoses cases, KOH examination (direct microscopy) and/or mycological cultures were positive in six boys, in whom candida glabrata and C. tropicalis grew. Older age and higher number of siblings were found to be significant factors for fungal infection.- - - - - - - - - - ranking = 2keywords = tinea (Clic here for more details about this article) |
4/20. Rapid response of trichophyton tonsurans-induced onychomycosis after treatment with terbinafine.We describe an 8-year-old Hispanic female who presented with distal subungual onychomycosis and tinea capitis. Both foci of infection yielded trichophyton tonsurans upon culture, and were clinically and mycologically cured with terbinafine 125 mg, once daily for 1 week [corrected]. This aspect of treatment with terbinafine has not previously been reported.- - - - - - - - - - ranking = 1keywords = tinea (Clic here for more details about this article) |
5/20. Cutaneous hyalohyphomycosis and onychomycosis caused by Onychocola canadensis: report of the first case from turkey.We present the first Turkish case of skin and nail infection due to Onychocola canadensis in an otherwise healthy farmer who frequently worked barefoot on soil. Cutaneous involvement consisted of scaly and hyperkeratotic lesions resembling tinea pedis, erythematous plaques, and dermal papulonodules of various sizes simulating Majocchi's granuloma. Repeated cultures from nail plates, skin scrapings and needle aspiration materials from papules or nodules all yielded the same mold on Sabouroud dextrose media with and without cycloheximide, trichophyton agar, and potato dextrose agar at 26 degrees C. The causal isolate was identified as Onychocola canadensis Sigler gen. et sp. nov., a slow-growing arthroconidial hyphomycete, on the basis of its colonial and microscopic morphology. While skin lesions were responsive to daily itraconazole in a dose of 200 mg for three months, the onychomycosis was resistant to therapy. To our knowledge, this is the first presentation of O. canadensis as the cause of cutaneous hyalohyphomycosis to date.- - - - - - - - - - ranking = 1keywords = tinea (Clic here for more details about this article) |
6/20. onychomycosis due to Onychocola canadensis.Onychocola canadensis is an uncommon nondermatophyte mould which can occasionally cause onychomycosis, and rarely, tinea manuum. It typically affects elderly individuals, some of whom have been farmers, in temperate climates. We describe a patient with onychomycosis due to this organism. She failed to respond to a 12-week course of terbinafine 250 mg o.d.- - - - - - - - - - ranking = 1keywords = tinea (Clic here for more details about this article) |
7/20. Scytalidium hyalinum isolated from the toe nail of an Australian patient.The isolation of Scytalidium hyalinum from the toe nail of a patient from Melbourne is reported. This is the first record of the isolation of this fungus from a clinical site in australia. A brief history is given of the occurrence of Scytalidium hyalinum and the related fungus, Hendersonula toruloidea, in tinea pedis and tinea unguium in immigrants to the United Kingdom from tropical countries. attention is drawn to the possible presence of these dermatophyte-like infections in patients in australia.- - - - - - - - - - ranking = 2keywords = tinea (Clic here for more details about this article) |
8/20. erythema nodosum in patients with tinea pedis and onychomycosis.To document association between erythema nodosum and concomitant fungus infection, we studied seven white women seen during a six-year period in our office practice. Five patients are presented. Unilateral erythema nodosum occurred in three patients on the same side as unilateral tinea. Tests with potassium hydroxide (KOH), cultures of nodules on Sabouraud agar and dermatophyte test medium (DTM), skin biopsy, and clinical examination ruled out nodular granulomatous perifolliculitis of Wilson. Lesions simulating erythema nodosum were produced when trichophyton antigen was injected subcutaneously in the lower legs. All nodose and fungal lesions cleared after griseofulvin therapy. Fungus infection of feet or nails should be considered a possible cause of erythema nodosum when no other cause is apparent.- - - - - - - - - - ranking = 5keywords = tinea (Clic here for more details about this article) |
9/20. trichophyton rubrum in the external auditory meatus.We report the case of a 28-year-old immunocompetent male suffering from otitis externa. The right external auditory meatus was filled with cerumen and detritus, the tympanic membrane covered wallpaper-like with layers of fungi. Mycological analysis revealed trichophyton rubrum. With further examination tinea pedis of plantar and interdigital type and concomitant onychomycosis of the toenails due to T. rubrum could be detected. The auditory meatus was cleaned and treated topically with clotrimazole. Two weeks later the auditory meatus and the tympanic membrane were bare of fungi and the inflammation was resolved. Treatment of tinea pedis and onychomycosis with terbinafine (systemically and topically) is still lasting.- - - - - - - - - - ranking = 2keywords = tinea (Clic here for more details about this article) |
10/20. onychomycosis caused by an isolate conforming to the description of trichophyton raubitschekii.trichophyton raubitschekii is currently regarded as a synonymous name betokening a variant form of trichophyton rubrum. Nonetheless, isolates conforming to this morphotaxonomic concept have morphological, physiological and clinical features very different from those of typical T. rubrum. Isolates are mainly obtained from subjects originating from certain tropical and subtropical countries, and are mainly obtained from upper body skin infections, rarely from onychomycosis. In this paper the authors report the first known Italian case of onychomycosis caused by such an isolate. The patient, a male student from cameroon, had a typical fingernail tinea unguium, without any other sign of skin or nail infection. 'T. raubitschekii' was identified on morphological and physiological grounds by the following features: velvety colony surface, brownish pigment, abundant macroconidia and microconidia, and positive urease activity. Such isolates may prove very difficult to identify correctly, especially in areas like italy where T. rubrum is normally seen only as isolates presenting a strongly differing phenotype.- - - - - - - - - - ranking = 1keywords = tinea (Clic here for more details about this article) |
