Trichophyton tonsurans is a major causative agent of tinea capitis in the United States, Canada, Mezico and other Latin American countries, but the infection of T.tonsurans has not been reported in Korea. We report a case of tinea capitis caused by T. tonsurans in a 15-year-old student wrestler. He had a 3*3cm sized non-inflammatory alopecia with black dots on the right occipital area of the scalp. The diagnosis was established by a hght microscopic examination of the affected hairs and by mycological studies from cultures. To our knowledge, this is the first case in which T. tonsurans has been isolated in Korea, It is likely that the student acquired the infection through contact with a foreign wrestler during interaational games and practice. We should be concerned about the potential of spread of this infection in our country.

Recently, several reports of extrahepatic hepatocellular carcinoma metastasis demonstrated by technetium-99mTc-IDAs scan have shown that 99mTc-IDAs can be used to detect extrahepatic metastasis in hepatocellular carcinoma. We report here a case of hepatocellular carcinoma with pulmonary nodules that were demonstrated as metastasis in nature by the use of the 99mTc-DISIDA. The findings in this case and several reports reviewed here suggest that the 99mTc-DISIDA scan may be a useful diagnostic agent that can detect the extrahepatic metastasis of hepatocellular carcinoma and stage the disease. But more clinical study in needed to establish the position of 99mTc-DISIDA in the field of diagnosis of extrahepatic hepatocellular carcinoma.

As a growing number of surgeons are perforining cataract extraction by phacoernulsification and the continuous curvilinear capsulorhexis [CCC] has rapidly increased in popularity as the anterior capsulotomy technique, its advantages have been reported recently. But its complications induced by capsular contraction after ccc have been noted, and so we have studied the change in anterior capsular opening area and refractive error after ccc. One surgeon performed cataract extraction using ccc and phacoernulsification, and implanted posterior chamber IOL [optic size 5. 5mm, Pharmacia 812A] in the bag in 48 eyes, and we measured the area of anterior capsular opening and refractive error [spherical equivalent] at I week and 3 months after operation. The average percentage of anterior capsular shrinkage rate at 3 months was 14.8% and showed statistically significant difference [P<0.05], but. had not correlation with initial ccc size. The average refractive change at 3 months was 0. 2D hyperopic shift but did not show statistically significant difference.

Ossifying fibroma is not a well recognized entity, and only rarely affects the long bones. The main differential diagnosis is with fibrous dysplasia and with adamantinoma, non-ossifying fibroma of the long bone. Ossifying fibroma seldom has even a moderate tendency to progress during childhood, but it recurs frequently after curettage or subperiosteal resection. Any progression of the lesion comes to an end after puberty. So, surgery should be delayed as long as possible. But, if the lesion is rapidly progressive, or if a patient has repeated fractures, it would be necessary to resort to wide extraperiosteal resection. We have experienced 7 cases of ossifying fibroma from Octover 1979 to November 1988. The results were as follows; 1. The male and female ratio, was 5 to 2 and six patients were at their first decade, and one patient was 13 years old. 2. The lesion site was six cases in the tibia, one case in the fibula. 3. In six patients, we had done wide resection with free-vasculaized fibular graft in five cases and wide resection of the distal one-third of the fibula in one case. Two patients among them had recurrence. One case of recurrence was performed incomplete wide resection with free vascularized fibular graft because the lesion was too close to the distal epiphysis of the tibia.

PURPOSE: To investigate quantitative and morphometric endothelial changes in phakic eyes implanted with an iris-fixed phakic intraocular lens in Korean patients. METHODS: We prospectively examined the endothelial cell density (ECD), ECD loss (ECL), coefficient variations (CV), and frequency of Hexagons (6A) in 46 phakic eyes implanted with an iris-fixed phakic intraocular lens. The effect of anterior chamber depth (ACD) and diopter of iris-fixed phakic intraocular lens on ECD was statistically analyzed. RESULTS: Preoperative mean ECD was 2923+/-257 cells/mm2. ECL at postoperative 1, 3, 6, 12, and 24 monthswas 0.71%, 0.88%, 0.70%, 0.64%, and 2.34%. It was significant only in the month 24 results. The mean CV value at the same time was 0.343, 0.342, 0.334, 0.329, 0.326, and 0.338. The change was significant at the 12th month. The mean 6A value at the same time was 58.2%, 57.8%, 59.7%, 59.6%, 60.1%, and 58.8%. There was no significant change in 6A value. Preoperative ACD and diopter of iris-fixed phakic intraocular lens didn't affect the ECD change. CONCLUSIONS: This two-year follow-up study of changes in endothelial cells after implantation iris-fixated phakic intraocular lens showed statistically significant decreases in the cells, which is not very significant considering the physiologic reduction rate of the cells. Thses decreases showed a tendency to be stabilized with recovery of morphological changes. Further long-term follow-up is needed to determine its long-lasting effect.

BACKGROUND: Tinea pedis is one of the most comrnon dermatoses in the general population. But its prevalence in the general populat,ion was not yet reported in Korea. OBJECTIVE: Prevalence of tinea pedis and associated tinea unguium were checked in the general population. METHODS: Six hundred fifty eight persons from 179 families of the college students were evaluated. Clinical examinatior. for tinea pedis and onychomycosis and collecting scales from the suspicious lesions of the family members were perforrned by educated college students. Then dermatologists exarnined those specimens mycologically by KOH ~tnount and fungal culture. RESULTS: The results were as follows 1. The prevalence of tinea pedis was 41.2% in the studied 658 persons. 2. Among all 271 patients with tinea pedis, 201 strains of dermatophytes were isolated. They were 143 strains of Trichophyton(T) rubrum, 49 strains of T. mentagrophytes and 9 mixed infections of T. rubrum and T. mentagrophytes. In the co existence of i,inea pedis and tinea unguiurn, isolated species were corresponding. 3. Among 179 families, 143 families (79.9%) had at least one patient with tinea pedis. The isolated species of derrnatophytes in a farnily were one organism, 71.4% and two or more organisms, 28.6% of 77 familiys with more than one patient. CONCLUSION: In our study, the prevalence rate of tinea pedis was 41.2%. That suggests that tinea pedis is a wide spr .ad disease in healthy adult in Korea.
