[Case of sycosis candidiasis on the upper lip].

A 72 year-old man was referred to our department with white curd-like material on the surface of his tongue as well as the mucosal surface of the lower lip, after unsuccessful treatment with itraconazole for 3 weeks. He also had a history of depression and had received topical steroid and/or antibiotics treatment for persistent oral aphtha and irritation of his upper lip for 4 years. A diagnosis of oral candidiasis was made through positive KOH direct microscopic examination and he was instructed to rinse his oral mucosal lesion with amphotericin B syrup. Although no significant eruption was observed on his upper lip at his first visit, he applied the steroid ointment for 4 weeks and came back to our clinic with his upper lip red and swollen. It was also covered with yellow crusty material mixed with a pustule. Histological examination of the lips revealed non-specific chronic inflammation in the mid to lower dermis. Hyphae in the cornea detected by PAS and Grocott staining. KOH direct microscopic examination from the pustule and crust showed positive pseudohyphae although no sign of parasitism to the hair was seen. Candida albicans and Candida parapsilosis were detected by culture from the crust and a biopsy sample. He was successfully treated with 2 courses of pulse therapy of oral itraconazole for sycosis candidiasis, accompanied by 2% miconazole gel for oral candidiasis.

Dose-finding comparative study of 2 weeks of luliconazole cream treatment for tinea pedis--comparison between three groups (1%, 0.5%, 0.1%) by a multi-center randomised double-blind study.

Luliconazole is a newly developed imidazolyl antifungal agent. A randomised double-blind comparative study was designed to assess the efficacy and safety of 1% luliconazole cream (group A), 0.5% cream (group B) and 0.1% cream (group C), in tinea pedis (interdigital type and plantar type), when used once daily for 2 weeks. Follow-ups were performed at 4 weeks after the end of topical treatment. A total of 241 patients were enrolled and 213 patients were evaluated for efficacy. Rates of improvement of skin lesions in the A, B and C groups assessed at week 4 were 90.5%, 91.0% and 95.8%, respectively. Rates of mycological cure (negative result of microscopy) in the A, B and C groups assessed at week 4 were 79.7%, 76.1%, 72.2% and at week 6 (at 4 weeks after the end of topical treatment) were 87.7%, 94%, 88.9%, respectively. For the mycological effect on tinea pedis of the interdigital type at 2 weeks, the negative conversion of fungi showed a concentration-dependent relationship and indicated a difference in tendency statistically 81.1% (1%- treatment), 62.9% (0.5%- treatment), 58.3% (0.1%- treatment) (Fisher's exact test, P = 0.079) and there was a trend between three groups by Cochran-Mantel-Haenszel method (P = 0.038). The incidence of adverse events in which a causal relationship to this drug could not be ruled out was low (2.6%). All of the adverse events were mild in severity and insignificant clinically.

A comparative clinical study between 2 weeks of luliconazole 1% cream treatment and 4 weeks of bifonazole 1% cream treatment for tinea pedis.

The aim of the study was to compare the efficacy and safety of luliconazole 1% cream and bifonazole 1% cream as applied in the treatment of tinea pedis (interdigital-type and plantar-type). A multi-clinic, randomised single-blind, parallel group study with 34 hospitals and 11 clinics formed the study design. Five hundred and eleven patients with mycologically confirmed tinea pedis were included. Of the 489 evaluable patients, 247 were randomised to luliconazole, and 242 to bifonazole. Luliconazole 1% cream applied once a day for 2 weeks, followed by a placebo cream for 2 weeks, thereafter. Bifonazole 1% cream applied once a day for 4 weeks. Mycological effect (negative result on microscopy) and improvement of skin lesions were measured at weeks 1, 2, 3 and 4. Safety frequency and severity of adverse reactions were also measured. The improvement of skin lesions after 4 weeks was comparably good with rates of 91.5% vs. 91.7% (luliconazole vs. bifonazole). The mycological effect was characterised by high negative rates of 76.1% vs. 75.9% (luliconazole vs. bifonazole). The progression of tinea-related signs and symptom scores differed insignificantly between evaluated luliconazole and bifonazole treatment groups comprising a total of 500 patients. Both substances appeared to be comparably safe and well-tolerated.

[A case of cutaneous Paecilomyces lilacinus infection on the face].

A 74-year-old woman presented in April, 2003, with cutaneous lesions of the face by Paecilomyces lilacinus infection. The patient had received predonisolone and azathioprine for 20 months for treatment of autoimmune hemolytic anemia. The lesion first developed on the right lateral eyelid 1.5 years earlier, and gradually enlarged. Physical examination revealed a dark reddish or brownish plaque and scattered papules and abscesses around the plaque on right lateral and lower eyelids, and the cheek. She noted mild tenderness on pressure. Cultures obtained from pus and biopsy specimen showed moulds, and those were identified as Paecilomyces lilacinus. Griseofulvin, 500 mg per day, was not effective for the lesion, so itraconazole, 200-300 mg per day, was administered orally for 11 weeks. Since culture from pus still yielded P. lilacinus despite clinical effectiveness, itraconazole pulse therapy (400 mg daily, 7 days a month) was started. The lesion cleared after three cycles of the pulse therapy.

[Environmental Isolates of Sporothrix schenckii in China].

Restriction fragment length polymorphism (RFLP) in mitochondrial DNA (mtDNA) from 25 environmental isolates of Sporothrix schenckii from northeastern China was investigated. Based on the mtDNA-RELP patterns with Hae III, 6 isolates were confirmed to be S. schenckii, while the other 19 isolates were confirmed to be species distinct from S. schenckii. The mtDNA RFLP patterns of the 19 non-S. schenckii were identical to each other. The non-S. schenckii isolates could not be discriminated from S. schenckii by their macro- or micro-morphological features, and were not pathogenic in guinea pigs. Serological and delayed hypersensitivity cross-reactions were found between S. schenckii and the non-S. schenckii species, suggesting antigenic similarity. These results indicate that RFLP analysis of mtDNA is essential for the identification of environmental isolates of S. schenckii.
