We analysed a retrospective study of 22 aphakic bullous keratopathy patients (22 eyes) with penetrating keratoplasty for 5 years from January 1987 to December 1991 in the Department of Ophthalmology at St. Mary's Hospital, Catholic University Medical College. The results were as follows; 1. Of the 22 eyes with aphakic bullous keratopathy 16 eyes (72.7%) had previously undergone intracapsular cataract extraction, 6 eyes (27.3%) had extracapsular cataract extraction. 2. The mean time from cataract extraction to aphakic bullous keratopathy to penetrating keratoplasty was 13.8 months. 3. After keratoplasty, the visual acuity of 20 among the 22 transplants (90.9%) were significantly improved compared to the preoperative levels, however that of 2 among the 22 transplants were worse than the preoperative levels. The factors limiting postoperative visual acuity were senile macular degeneration and graft failure. 4. Postoperative complications were glaucoma (2 eyes, 9.1%), cystoid macular edema (1 eye, 4.6%) and graft failure (1 eye, 4.6%).

BACKGROUND: Varix bleeding in children is infrequent but it is potentially fatal. It has characteristics different from adult age varix bleeding. But there was little clinical data about it. The purposes of this study is to detect its characteristics of varix bleeding in pediatric patients, and to help an emergency physician make a decision about the management. METHODS: We reviewed medical records of 32 patients who visit Seoul National University Hospital Pediatric Emergency center from Jan. 1, 1995 to Dec. 31, 1996. RESULTS: 1) The peak age was between 1 and 5 years of age, and the ration of males to females was 1: 1. 2) As a underlying cause, intrahepatic disease were more common than extrahepatic diseases(87.1%:12.9%). 3) 10 patients(31.3%) had URI symptoms as a precipitating factor. 4) Varix bleeding has a circardian rhythm, and occured more often during the night. 5) In Child Classification for the hepatic reserve fuction, Child C was the most common(75%). 6) Endoscopic eliminations were performed in 14 patients(43.8%). 7) According to shock classification. the ration of conservative to vasopressin treatment in class I and class II were 13(40.6%)/10(31.3%) and 6(18.8%)/3(9.4%), respectively. 8) Fever was the most common complication(43.8%), and the mortality rate was 3.1%. CONCLUSION: We suggest that the only conservative management can show a good result far pediatric varix bleeding compared to other treatment modalities.

BACKGROUND: Paraquat is widely used herbicide. But if it is ingested by accident or by suicidal attempt it causes severe toxicity. And in emergency room, it is a big problem that there is no effective treatment modality for paraquat intoxication. It is reported that the mechanism of toxicity is by oxygen fee radical. And Vitamin C is known as potent antioxidant. This study was designed to evaluate the antioxidant effect of Vitamin C to lipid peroxidaton in paraquat intoxication. METHODS: 24 rats were divided to 6 groups after paraquat injection(20mg/kg), and each groups 4 rats. In 2 control groups we only observed until 6 hours and 24 hours. And Vitamin C of 10 mg per kilogram body weight on the low dose group and 100 mg per kilogram body weight on the high dose group were infected simultaneously. And in 6 hours group, after 6 hours of paraquat and vitamin C injection biochemical levels of malondialdehyde, superoxide dismutase and catalase were measured in liver and lung. And in 24 hours group after 24 hours the same measures were done. The stasistical methods used were ANNOVA and Mann-Whitney test and P-value was 0.05. RESULTS: Malondialdehyde level of high dose Vitamin C group was significantly low compared to that of the control groups in liver tissues after 24 hours(p<0.05). And in lung tissues both low dose and high dose vitamin C groups show significantly low level of malondialdehyde level after 24 hours(p<0.05). On the superoxide dismutase activity, only high dose Vitamin C group shows significantly high level in 24hours both in liver and lung tissues. And the catalase activity is significantly elevated in high dome Vitamin C group after 24hours both in liver and lung tissues. (p<0.05) CONCLUSION: High dose Vitamin C suppresses lipid peroxidation, increases catalase activity and superoxide dismutase activity in paraquat intoxiation. It is thought to by antioxidant elect of vitamin C but it's effect is observed only in 24 hours after intoxication.

BACKGROUND: Inflammatory mediators, including oxidants, play a important role in the systemic response to burn injury and cause a sepsis and subsequent multiple organ failure by lipid peroxidation of cell. It has been known that vitamin C has potent antioxidant effect and inhibits the lipid peroxidation. This study was designed to evaluate the inhibitory effect of vitamin C about lipid peroxidation in the early stage of bum injury. METHODS: 15 rats with second degree bum on 30-35% of body surface were divided into three groups. Only normal saline was injected into intraperitonial space on the control group , and vitamin C of 50 mg/kg of body weight was added on the low dose group (LDG), and vitamin C of 500 mg/kg of body weight on the high dose group (HDG). After 24 hours of bum damage, biochemical levels of malondialdehyde (MDA), superoxide dismutase (SOD) and catalase were measured in lung and liver tissue. The statistical methods used were Kruskal-Wallis test and Mann-Whitney test. RESULTS: MDA levels of LDG and HDG were significantly low compared to that of the control group (p<0.01). On the catalase activity, there was no significant difference when comparing the control group with LDG (p=0.015), but significant difference with HDG (p<0.01). There was no significant differences between three groups on the activities of SOD (p>0.01), except comparing the control group with HDG in lung tissue (p<0.01). CONCLUSION: Vitamin C therapy in the early stage of bun decreased the level of MDA and increased the catalase activity. It means that vitamin C inhibits the lipid peroxidation and has antioxidant effect. But vitamin C revealed the only partial effect on the SOD activity.

BACKGROUND: Endometrial carcinomas are pathogenetically classified into two major types; endometrioid carcinoma (EC) and serous carcinoma (SC). The most frequently altered gene in EC is the PTEN tumor suppressor gene (TSG). SC is usually associated with mutations in the p53 TSG. METHODS: To further determine the role of PTEN and p53 mutation in endometrial carcinogenesis, the analysis of 33 endometrial carcinomas, including 28 ECs and 5 SCs, for loss of heterozygosity (LOH) on 10q23 and for mutation in all 9 coding exons of PTEN and the 5-8 exons of p53, using SSCP-PCR methods was carried out. RESULTS: LOH was detected in at least one marker in 12 (54.5%) of 22 ECs, but in only one (20.0%) of 5 SCs. Somatic PTEN mutations were detected in 10 (35.7%) of 28 ECs. PTEN was altered in 67.9% of ECs and in 20.0% of SCs, including those with 10q23 LOH. No PTEN mutations were found among the SCs. Somatic p53 mutations were detected in 2 (7.1%) of 28 ECs and 3 (60.0%) of 5 SCs. CONCLUSIONS: PTEN gene alterations contribute to the pathogenesis of an endometrioid subtype of endometrial carcinoma, but not to the serous type. In contrast, p53 plays an important role in the pathogenesis of SCs.

Trichinosis is a food-borne zoonotic disease caused by the nematode, Trichinella spp., and had been reported several times in Korea. Recently, there was an additional outbreak, involving 5 patients, the findings from which are reported herein. On 30 November 2010, 8 persons ate sashimi of the meat of a wild boar. Then, 2-3 weeks later, they complained of myalgia and fever. Unfortunately, muscle biopsy was not performed, but ELISA was performed using their sera. Two people among 8 were positive for Trichinella on the 34th day post-infection (PI), and 3 patients who initially revealed negative ELISA were additionally proved to be positive for trichinosis on the 42nd day PI. Hence, the confirmed patients of trichinosis were 5 in total in the present outbreak. They were treated with albendazole and discharged uneventfully. This was the fifth outbreak of trichinosis in Korea.

OBJECTIVE: The purpose of this retrospective study is to evaluate the efficacy of Loop Electrosurgical Excision Procedure (LEEP) in the diagnosis and in the treatment of CIS (carcinoma in situ). METHODS: Between Jan. 1999 and Apr. 2000, 94 patients with CIS were treated in the Hallym University Sacred Heart Hospital. Three procedures were performed: cytology, punch biopsy and LEEP (loop electrosurgical excision procedure). And the results of cervical cytology, punch biopsy, phathologic diagnosis of LEEP specimens were evaluated in comparison with the pathologic diagnosis of hysterectomy specimens. RESULTS: Followings are results summarized. 1. The concordance rate of LEEP histology with punch biopsy was 60% (53 cases). In comparison to punch biopsy, the higher LEEP histologic rate was 22% (19 cases), and lower LEEP histologic rate was 18% (16 cases), respectively. 2. 67 patients were diagnosed CIS and among them 58 patients underwent hysterectomy. In histologic comparison between LEEP and hysterectomy, there were on 1 (1.7%) patient who had more advanced diagnosis after operation. 3. 67 patients were diagnosed CIS and among them 58 patients underwent hysterectomy. The residual lesion was identified in 19 of 58 patients (33%). CONCLUSION: LEEP was useful diagnostic tool in CIS. But, in therapeutic efficacy, simple LEEP seems to be incomplete. Therefore, when we use LEEP for CIS as therapeutic tool, additional procedure, such as wide excision or endocervical deep resection may be asked. And careful follow up asked in therapeutic LEEP.

BACKGROUND: Hypoparathyroid patients often have a higher bone mineral density (BMD) than the general population. However, an increase in BMD does not necessarily correlate with a solid bone microstructure. This study aimed to evaluate the bone microstructure of hypoparathyroid patients by using hip structure analysis (HSA). METHODS: Ninety-five hypoparathyroid patients >20 years old were enrolled and 31 of them had eligible data for analyzing bone geometry parameters using HSA. And among the control data, we extracted sex-, age-, and body mass index-matched three control subjects to each patient. The BMD data were reviewed retrospectively and the bone geometry parameters of the patients were analyzed by HSA. RESULTS: The mean Z-scores of hypoparathyroid patients at the lumbar spine, femoral neck, and total hip were above zero (0.63±1.17, 0.48±1.13, and 0.62±1.10, respectively). The differences in bone geometric parameters were site specific. At the femoral neck and intertrochanter, the cross-sectional area (CSA) and cortical thickness (C.th) were higher, whereas the buckling ratio (BR) was lower than in controls. However, those trends were opposite at the femoral shaft; that is, the CSA and C.th were low and the BR was high. CONCLUSION: Our study shows the site-specific effects of hypoparathyroidism on the bone. Differences in bone components, marrow composition, or modeling based bone formation may explain these findings. However, further studies are warranted to investigate the mechanism, and its relation to fracture risk.
