ABSTRACT
BACKGROUND: Since the bioavailability of itraconazole capsule is influenced by patients gastric acidity, it results in treatment failure due to its low dissolution and subsequent low absorption when administered in fasting. Itraconazole Melt-Extrusion tablet has been lately developed in order to improve its dissolution profile. It is the first clinical study to evaluate the efficacy and safety of itraconazole Melt-Extrusion tablet in Korea. OBJECTIVE: This study was conducted to evaluate the efficacy and safety of itraconazole melt-extrusion tablet 400mg daily for 1 week(pulse therapy) for hyperkeratotic type of tinea pedis and manus. METHODS: A clinical and mycological investigation was made of 812 outpatients with hyperkeratotic type of tinea pedis and/or tinea manus who had visited at 52 general hospitals under the lead of the Korean Dermatological Association from June to December, 1998. Patients confirmed by clinically and microscopically as hyperkeratotic type of tinea pedis and/or tinea manus were administered 2 tablets twice a day for one week and followed up for 8 weeks from the start of the medication. RESULTS: The results were summarized as follows; 1. Clinical symptoms of hyperkeratotic type of tinea pedis and/or tinea mauns were significantly improved at the end of study, week 8(p<0.001). 2. Clinical response rate, defined as more than 50% decrease of the sum of the clinical symptom scores, was 79.3%(512/646). 3. Mycological cure rate, dafined as both culture and KOH negative at week 8, was 78.2%(244 /312). 4. 40(5.5%) patients, of the 727 patients evaluable for drug safety evaluation, were reported to have adverse event. CONCLUSION: Itraconazole Melt-Extrusion tablet 400mg/day for 1 week (pulse therapy) is effective and safe in the treatment of hyperkeratotic type of tinea pedis and/or tinea manus.

Alopecia areata is a common cause of acquired circumscribed alopecia in childhood. In infancy alopecia areata is exceptional. No case of congenital alopecia areata has been documented yet. Thus, it is generally assumed that alopecia areata is acquired only postnatally, and it is believed that the presence of an alopecia at birth virtually excludes the diagnosis of alopecia areata. In this report, we document a case of congenitally developed alopecia areata that shows typical clinical and histological features of alopecia areata.

Papular xanthoma is a newly classified type of normolipemic xanthoma that resembles juvenile xanthogranuloma and xanthoma disseminatum. Papular xanthoma is asymptomatic multiple yellowish papules with granulomatous lesion composed of foam cells and few giant cells, with scarce inflammatory cell infiltration. We report a case of papular xanthoma in a 3-year-old girl who showed typical clinical manifestation. She had multiple discrete, 0.2 to 0.5cm sized elevated dome-shaped yellowish papules on the trunk and face for 2years. Histopathologic findings showed granulomatous changes mainly composed of foam cells and few histiocytes, in the dermis.

A 58-year-old male presented with a pruritic, erythematous hread-like eruption on the right chest, which appeared as a small papule since 6 months prior to his visit. Histopathologic examination showed a burrow containing numerous eosinophiles and a few mononuclear cells in the epidermis. There was focal spongiosis unde the burrow. In the dermis, there was a diffuse and occasionally dense perivascular and periadnx 1 inflammatory cell infiltration consisting of eosinophiles and some lymphocytes. Multiple histologic sections were made without success in deizo strating parasitic tissue in the epidermis, however, the clinical and histopathologic features we onsistent with cutaneous larva migrans.
