The dematiaceous fungi, characterized by having melanin in their cell walls, have become significant due to an increasing cause of human skin disease in Korea. The disease caused by dematiaceous fungi contain pityriasis (tinea) nigra, onychomycosis (in part), black piedra, keratomycosis (in part), chromoblastomycosis, phaeohyphomycosis, and eumycotic mycetoma (in part). Chromoblastomycosis is subcutaneous mycotic disease that contain sclerotic cells and histologically show pseudoepitheliomatous hyperplasia with microabscess, and phaeohyphomycosis is a group of mycotic infections that contain dematiaceous yeast-like cells, pseudohypae-like elements, hyphae or combination of these form in tissue.

Tricosporon(T.) cutaneum is a member of the subfamily Trichosporideae in the family of Cryptococcaceae. It is now regarded as the same species as Trichosporon beigelii. It is widely distributed in soil, and is sometimes a part of the normal flora of the human skin, nail and mouth. It also may rarely colonize the throat and lower gastointestinal tract in hospitalized patients. T. cutaneum may cause white piedra in immunologically normal patients, a disease characterized by surface hard nodules along the hair shaft, however, skin infection by this organism is rare, T. cutaneum is referred to by Emmons as the agent of subcutaneous and systemic fungal infection. We report a case of subcutaneous infection with T. cutaneum in a kidney transplanted patient.

Trichosporon beigelii is a causative agent of white piedra, an superficial hair shaft infection in immunocompetent individuals, and rarely of disseminated trichosporonosis in immunocompromised patients especially in neutropenic patients with leukemia. Trichosporon infections in immunocompromised patients are frequently fatal despite therapy with amphotericin B. We describe an acute myelogenous leukemia patient with T. beigelii fungemia after remission induction chemotherapy who was successfully treated with amphotericin B and fluconazole.

PURPOSE: AHC characterized by sudden onset of gross hematuria, dysuria and frequency occurs in children and young adults as a self-limited disease that should be differentiated from serious renal disorders. We have performed this study to establish the cause and characterize the clinical features of this illness in Korean children. METHODS: 19 cases collected prospectively for 30 month-period over 1991-1993 were reviewed. Urine specimens were obtained after normal voidings and inoculated into Hep-2 cell monolayers for virologic study, and cultured as standard method for bacteria. Isolates producing a cytopathic effect characteristic of adenovirus were confirmed by indirect immunofluorescent staining with monoclonal antibody specific to adenovirus and also by electron microscopy. Adeno-viruses were typed by hemagglutination-inhibition test by Dr. Piedra at the Texas Medical Center, USA. RESULTS: The ages of the patients were between 5 months and 14 years. Adenovirus was isolated from the urine in 8 cases(42%) and E. coli in 2(10.5%). Of 8 patients with positive culture, adenovirus type 7a was recovered in 4 cases, and adenvirus type 11 in 4 cases. Seven of the 8 patients with positive adenovirus culture were boys while E. coli was isolated only in girls. No sexual difference was found in cultur-negative group(M:F=4:5). The sudden onset of painful hematuria was the most impressive manifestation. Gross hematuria continued for 3 to 15(average 8.9) days. Suprapubic pain was present in 4. Only one patient had mild fever. Ten of 11 ultrasonic examinatinons showed thickening of bladder wall and decreased filling capacity. CONCLUSIONS: These data suggest that culture for viruses may be useful method for differential diagnosis of AHC and adenovirus type 7a is newly identified to be one of the important causes of this illness. Further studies on ABC are needed to investigate the unexplained part of etiology.

Blastoschizomyces capitatus (formerly Trichosporon capitatus) causes piedra and sometimes invasive infections in immunocompromised hosts. Arthritis by B. capitatus in a previously healthy person has not been reported. Herein we experienced a case of pyogenic arthritis of the knee joint in a farmer and reported the clinical course and literature review. A 68-year old man was adimitted because of swelling and painful left knee joint. Under the impression of septic arthritis of the left knee, empiric antibiotic treatment was initially done. On fifth admission day, B. capitatus was reported in joint fluid culture for the first time. Arthroscopic finding revealed infected synovium and pus-like fluid collection on patello-femoral joint. Amphotericin B was tried but discontinued due to hypokalemia after 7 day use. Secondary arthroscope showed subchondral destruction on medial femoral condyle and medial tibial plateau. Eight week treatment with parenteral fluconazole (daily 100 mg) and oral ketoconazole (200 mg daily) resulted in complete resolution of the patient's symptom. But knee joint ankylosis was remained.
