1/10. Case report. First report on human ringworm caused by Arthroderma benhamiae in japan transmitted from a rabbit.

    Two human cases of tinea corporis due to Arthroderma benhamiae (teleomorph of trichophyton mentagrophytes) were described. They acquired the infection from their cross-bred rabbit. The three clinical isolates from a human couple and a pet rabbit had been identified as A. benhamiae by chitin synthase 1 (CHS1) gene analysis as well as by mating experiments. There was no previous isolate of A. benhamiae from humans in japan, although we had reported the first isolate of A. benhamiae from a rabbit in 1998. Therefore, this is the first report on human ringworm cases caused by A. benhamiae in japan. It is anticipated that the human and animal cases of A. benhamiae infection could rise in number.

2/10. A Japanese case of tinea corporis caused by Arthroderma benhamiae.

    We report a case of tinea corporis in japan caused by Arthroderma benhamiae. A 53-year-old female scientist, who had been working on dermatophytes in a laboratory, noticed pruritic erythema on the outer corner of her left lower eyelid. She used a steroid ointment for three days, but the lesion continued to expand. When she visited our clinic, the erythema was 15 mm in diameter and clearly demarcated with a slightly depressed center. A scale from the periphery of the erythema was positive with direct KOH examination, and T mentagrophytes was isolated from the lesion. The erythema was successfully treated with topical application of butenafine hydrochloride. The isolate was mated with a ( ) strain of the Americano-European race of A. benhamiae. Using the most sensitive molecular typing method, restriction exzyme analysis of the non-transcribed spacer region of the ribosomal dna, the restriction profile of the isolate was the same as that of strains used in her laboratory but different from those of any Japanese isolates associated with pet animals. The results suggest that the patient became infected during her experiment.

3/10. Hazards from hedgehogs: two case reports with a survey of the epidemiology of hedgehog ringworm.

    Two related cases of ringworm caused by contact with an infected hedgehog are reported. The causal fungus, trichophyton erinacei, was isolated from human and animal cases. The epidemiology of hedgehog ringworm is discussed.

4/10. Inflammatory ringworm with unusual features.

    Zoophilic dermatophyte infections are often inflammatory but severe widespread inflammatory lesions of glabrous skin, as in the female patient described, are unusual. Most cases of M. canis ringworm can be traced to an infected animal. This dermatophyte is associated with a variety of clinical presentations on glabrous skin and is being isolated with increasing frequency in some countries.

5/10. Perniosis-like tinea corporis caused by trichophyton verrucosum in cold-exposed individuals.

    trichophyton verrucosum is a zoophilic infectious agent causing 98% of the dermatophytic infections of cattle. Transmission to humans has, until recently, been rare. One reason for an increase of infection in humans and animals seems to be the decrease in immunisation of cattle. We report on three cases of pertinent human infections with disseminated, sharply defined, bluish red, partly oedematous nodules and plaques in particular not only on the thighs, but also on the trunk and arms. Two of our patients work with farm animals. The third one works as an assistant in a butcher shop, but lives on a cow farm. All three patients are often exposed to the cold. In all three cases T. verrucosum was detected by culture. tinea corporis was histologically confirmed in two patients. Based on the microbiological results, we began a combined systemic and local antimycotic therapy with fluconazole 50 mg day(-1) in two patients, itraconazole 100 mg day(-1) in one patient p.o. combined with topical ciclopiroxolamine. All patients were cured. Dermatophytosis caused by T. verrucosum can, under certain circumstances, such as frequent exposure to cold or a long-term corticosteroid therapy, mimic the characteristic clinical picture of perniosis, as we demonstrate here.

6/10. tinea corporis due to microsporum canis from an asymptomatic dog.

    The patient was a 19-year-old female student who purchased a puppy from a pet shop four weeks earlier. At the time of her first examination, an annular edematous erythema with adherent scales and vesicles surrounding its margin was seen on the left forearm. On direct examination of the vesicles, fungal elements were detected, and microsporum canis was isolated. The puppy was a Pomeranian and was kept in the house at all times. No clinical lesions were seen on the puppy, and the wood's lamp test was negative. However, M. canis was isolated from the animal by the hairbrush method. Symptoms disappeared after the patient was treated topically with terbinafine cream for three weeks. Although the dog received no treatment whatsoever, there was no evidence of the disease on the pet. Results of the hairbrush method performed on the pet two and three weeks later were negative, but, at five weeks, it was again positive. Human infection with M. canis from an asymptomatic dog was demonstrated in this case. attention should be paid to preventing infections from animals without lesions.

7/10. trichophyton simii infection in the united states not traceable to india.

    To our knowledge, this communication reports the first case of trichophyton simii infection in the united states not traceable to india, The patient was a 40-year-old Nigerian male student who had not been out of the united states for more than three years. He had never been in india or had contact with animals or poultry. A brief review of the literature is included.

8/10. Barn Itch.

    Particularly in rural settings, trichophyton verrucosum commonly causes an inflammatory tinea infection, sometimes called 'barn itch." There is usually a history of contact with animals. The demonstration of clusters of large spores in a potassium hydroxide preparation of scrappings obtained from clinically involved skin is useful in making a presumptive diagnosis of T. verrucosum infection. Cultures frequently are negative. Oral griseofulvin shortens the course of the disease.

9/10. Treatment of ringworm in calves using griseofulvin.

    Ringworm infection of a farm manager is described. Treatment of 10 ringworm-infected calves (group A) on the farm was undertaken with the daily administration of griseofulvin powder for seven days at a rate of 7.5 mg per kg body-weight and compared with nine infected control calves (group B). Group A showed fewer new lesions (22) than group B (80) and fewer new lesions per infected animal (3.7 and 11.4 respectively). The appearance of the last new lesions was earlier in group A (21 days) than in group B (56 days) and the duration of infection in the former group was less (49 days and 98 days respectively). Two control calves were not infected until after infection in group A had resolved.

10/10. tinea axillaris, a variant of intertriginous tinea, due to non-occupational infection with trichophyton verrucosum.

    The term tinea axillaris has been used only a few times in the literature. In this paper we describe a male patient with widespread tinea corporis and unguium affecting also both axillary regions. trichophyton verrucosum was isolated as the causative agent. The patient admitted to no direct contact with infected animals, but had lived in a rural area until a year before the infection became widespread. Topical treatment with glucocorticosteroids probably promoted propagation over large parts of his body and may have led to the infection of the axillary region, an unusual site for fungal infection. Treatment with itraconazole over 4 weeks led to complete clearing of all lesions on glabrous skin. Thereafter, itraconazole pulse therapy was used to treat the nail infection.
