Microsporum ferrugineum was the most common cause of tinea captis in Korea until the middle of the 1970s, but this organism has been only rarely isolated from the scalp ringworm during recent years. We report, three cases of tinea capitis occurring in a 2-year-old male, a 10 year-old female and a 5-year-old male. From all three patients, Microsporum ferrugineum was isolated.

The purpose of this study was to compare the corrosion characteristics between implant fixture and two types of abutment screw; gold screw, titanium screw. The anodic polarization behavior, the galvanic corrosion behavior, and the crevice corrosion behavior of prepared samples were investigated using potentiostat and scanning electron microscope. The results were as follows : 1. Anodic polarization behavior of samples: The primary passivation potential of implant fixture was -420mV, implant abutment was -560mV, titanium screw was -370mV and gold screw was -230mV. All samples were shown to have a high corrosion potential and good formation of passive film. The critical passive current density of gold screw was higher than of other samples and the sample of gold screw showed a unstable passive film formation at passive region. 2. Galvanic corrosion behavior of samples: Contact current density between implant fixture and titanium screw showed 8.023x 10-5C/cm2. Contact current density between implant fixture and gold screw showed 5.142x 10-5C/cm2. 3. Crevice corrosion behavior of samples : The crevice corrosion resistance of sample using titanium screw was higher than that of sample using gold screw, and a severe corrosion morphologies were observed at the fixture-screw interface by the scanning electron microscope.

Arrhythmogenic right ventricular dysplasia is a rare heart muscle disorder of unknown cause that primarily involves the right ventricle. It is characterized pathologically by fibrofatty replacement of the right ventricular myocardium. Clinical manifestations include structural and functional abnormalities of the right ventricle, electrocardiographic depolarization/repolarization changes, and presentation with sudden death or ventricular arrhythmias of right ventricular origin. It is one of the important causes of the ventricular arrhythmia or sudden death among apparently healthy young people. We report a case of arrhythmogenic right ventricular dysplasia with the review of the literature.

A 12-year-old boy showed a slatecolored scaly patch on h; ight face for 2 months. Histopathologic findings showed basal vacuolations and dermal me arphages with only scanty lymphoid cells in the fat tissue layer. Besides the facial lesion, lesions of edematous localized erythema were noted on his right if and left buttock with similar mi rocopical findings. 6 months later the facial lesion was aggravated like a cellulitis, of which thc bevpsy findings were consistent with mycosis fungoides. The patient received chemotherapy aftei the diagonsis for one month before his termination. Because of the rarity of mycosis fungoides in childhood age and its un common cutaneous lesions, the case is reported.

This study was carried out to investigate the localization and change of the cell surface antigens, such as URO-9(Om5) and URO-10 (T43), in transitional cell carcinomas of bladder. The subjects used were normal bladder mucosae of 10 autopsy cases of fetus and 10 biopsy cases of child or adult patients with disease of other organs as controls, and neoplastic tissue of 15 cases of patient with transitional cell in carcinoma of bladder. Avidin-Biotin complex(ABC) kits(Cambridge Research Lab.) and URO-9 and URO-10 monoclonal antibodies were used and the data observed were analyzed. The results obtained were summarized as follows: 1. URO-9 expression was none of 10 fetal bladder mucosae and 3 or 10 normal bladder mucosae and URO-10 expression was none showed. 2. Of 15 cases with transitional cell carcinoma of bladder, URO-9 expression was 5, of which 1 was Ta grade II, 1 T1 grade II and the rest T2 grade III. URO-10 expression was 10, of which I was T1 grade III, 3 T2 grade III, 3 T3 grade III and 3 T4 grade III, of 15 cases of transitional cell carcinoma of bladder. As above results, the transitional cell carcinoma of bladder in low grade and low stage have tendency to express URO-9 monoclonal antibody but not URO-10 monoclonal antibody, whereas the transitional cell carcinoma of bladder in high grade and high stage were inclined to express URO-10 monoclonal antibody with variable expression of URO-9 monoclonal antibody.

Recently, imaging diagnosis is valuable in detecting of primary malignancy and secondary malignancy. When urologic symptoms newly developed to the patients who had malignancy of digestive organs, metastatic malignancy of urogenital organs should be considered. Here, we report a case of metastatic bladder tumor from gastric cancer which occurred 9 months after subtotal gastrectomy.

Deep palmoplantar warts (Myrmecia) are frequently tender papules or plaques caused by HPV-1. Myrmecia are usually misdiagnosed as paronychia or digital mucous cysts. They occur not only on the palms and soles but also on the lateral aspects and tips of the fingers and toes. We report a rare case of deep palmoplantar wart occurring on proximal nail fold, unusual site of right 5th finger in an 11-year-old girl.

Posterior epidural migration of a sequestrated intervertebral lumbar disc is rare with only five cases ever reported in the literature so far. The objective of this paper is to report our experience of such a extremely rare case with a review the literature
