Purpose: The purpose of this study were to evaluate the results of arthroscopic PCL reconstruction and posterolateral structure reconstruction. Materials and Methods: We performed 10 cases of arthrocopic PCL and posterolateral structure reconstruction using allo-achilles tendon. The average follow-up period was 25 months. We performed KT-2000 testing and posterior drawer test for posterior instability and tibial external rotation test for posterolateral rotatory instability, and measure Tegner and Lysholm score preoperatively and compared these with the results of a final evaluation in each cases. Results: The Preoperative average KT-2000 tests was 7.1 mm, posterior drawer test was Grade III and tibial external rotation test was positive at both 30 and 90 degrees of knee flexion in all cases. Preoperative average Lysholm score was 65.9 and Tegner score was 3.1. At the final evaluation, an average KT-2000 test was 2.2 mm, posteior drawer test, Grade 0 was 2 cases, Grade 1.4 cases, Grade II, 3 cases, Grade III, 1 cases. The tibial external rotation test at both 30 and 90 degrees of knee flexion was positive in 1 cases and positive at only 90 degrees in 2 cases. Lysholm score was 87.6 and Tegner score was 5.7. The objective and subjective score of final evaluation is increased in compare with preoperative one. Conclusion: Arthrocopic PCL and posterolateral structure reconstruction using allo-achilles tendon is one of the good surgical treatment method in patients having posterior and posterolateral rotatory instability.

Purpose: To evaluate the outcome of symptomatic osteochondritis dissecans of the talus treated with arthroscopic debridement and multiple drilling. Materials and Methods: Between 1997 and 2003, 14 arthroscopic debridement(group I) and 15 arthroscopic multiple drilling(group II) were performed. There are 21 male and 8 female patients. Mean age was 34.4 years(33.8 years in group I, 37.5 years in group II) and average follow-up period was 43.2 months(46.4 months in group I, 40.1 months in group II). Simple radiographs and MRI were performed preoperatively and postoperatively, and the progressive stage of the lesions was evaluated through the arthroscopic surgery. Clinical results were evaluated with ankle-hindfoot scale and scoring scale for subjective and objective functional outcomes. The results were compared between 2 groups. Results: There are 20 medial(7 in group I, 13 in group II), 6 lateral(5 in group I, 1 in group II), and 3 both-side(2 in group I, 1 in group II) lesions. According to the classification of Berndt and Harty, there are 4 stage II(4 in group I, 0 in group II), 19 stage III(9 in group I, 10 in group II), and 6 stage IV(1 in group I, 5 in group II). According to the ankle-hindfoot score, the mean score was significantly improved $53.1{\pm}2.7$ points preoperatively to $85.1{\pm}8.5$ points postoperatively in group I and $54.6{\pm}6.8\;to\;80.7{\pm}8.5$ points group II. Subjective and functional scores was also improved $49.6{\pm}10.5$ points preoperatively to $84.6{\pm}7.7$ points postoperatively in group I and $50.7{\pm}9.2\;to\;83.0{\pm}9.6$ points in group II. But there were no statistical significance between them. Conclusion: Arthroscopic debridement and multiple drilling for the treatment of osteochondral lesions of the talus showed successful results and there was no statistically significant difference between them.

Objective: The purpose of this study is to find out risk factors related to uterine leiomyoma in Korean women and to compare with the results of previous western studies. Methods: A retrospective analysis was carried out. All the cases of uterine leiomyoma (n=244) were diagnosed surgically or sonographically between Jannuary 1998 and December 2004. Total of 269 controls not having uterine leiomyoma were collected from patients who visited Kyungpook national university hospital for routine gynecologic check-up or treatment of their gynecologic or obstetric diseases other than uterine leiomyoma. Data were collected through review of medical records and interviews and analyzed with $x^2$ and logistic regression model. Results: In multivariate analysis, patient's age (OR 1.070; 95% CI 1.041~1.099), number of artificial abortion (OR 1.182; 95% CI 1.018~1.374) and alcohol drinking (OR 1.865; 95% CI 1.231~2.824) had significantly positive correlation with uterine leiomyoma. The duration of lactation was the only factor which had negative correlation (OR 0.985; 95% CI 0.972~0.998). BMI, parity, age at menarche, the duration and interval of menstruation, caffeine consumption and marital status did not show any correlations. Conclusion: In this study, patient's age, number of artificial abortion, and alcohol drinking were the risk factors of uterine leiomyoma in Korean women and the result was similar to that of western studies. Though we couldn't find out the specific risk factors related to the development of uterine leiomyoma in this study, but it has a great meaning to be the first trial in Korean women. The role of information bias should be carefully evaluated and further multicentered, randomized, controlled prospective studies will be needed to know the possible risk factors among Korean women.

Purpose : The current nationally representative data on inpatient care are important to make the of the national public health policy because distributions and the prevalence of diseases among children and adolescents represent the socioeconomic status of the society. The prevalence of chronic disease is increasing now in Korea as the socioeconomic condition is improving. We analyzed a part of genitourinary tract disease of the cross-sectional hospital discharge survey data in Korea collected recently to delineate the trend of genitourinary tract diseases. Methods : Korean nationwide hospital discharge survey for pediatric inpatients in the period from 2004 to 2006 was analyzed. Diagnoses in the data were coded using ICD-10 classification. Totally 826,896 cases were collected from the 85 training hospitals. Selected data of genitourinary tract diseases (belonging to N00-N99 by ICD-10) among 826,896 cases of final inpatients data were analyzed for this study. Results : Among total patients of 826,896, diseases of the genitourinary system accounted for 4.1%. and four diagnostic categories accounted for 92.8%. These were other diseases of the urinary system (N30-39), 45.8%, disease of male genital organs (N40-51),19.1%, glomerular diseases (N00-08), 17.3%, renal tubulo-interstitial diseases (N10-16), 10.6%, respectively. Conclusion : Genitourinary tract disease in pediatric inpatient shows decreasing tendency but the prevalence of chronic diseases is increasing in Korea as the socioeconomic condition is improving. For further comprehensive analysis, regular and organized nationwide survey should be performed. Development of a new data collecting system will improve the performance of such nationwide survey.

Purpose : The aim of this study was to evaluate the clinical usefulness of measurement of ${\beta}_2$ microglobulin (${\beta}_2$ MG), N-acetyl-$\beta$-D-glucosaminidase (NAG) of spot urine samples as indices of renal tubular damage and microalbumin of spot urine samples as a parameter of glomerular damage in children with vesicoureteral reflux (VUR) or renal defects. Methods : We studied 91 children with previous UTI. The children were classified as 62 children without VUR and renal defects (group I), 10 children with VUR, without renal defects (group II), and 19 children with VUR and renal defects (group III). Patients having VUR were separated according to the degree of VUR (mild VUR: VUR grade I-III, severe VUR: VUR grade IV-V). Urinary excretion of ${\beta}_$ microglobulin (${\beta}_2$ MG), microalbumin, N-acetyl-$\beta$-D-glucosaminidase (NAG), creatinine were measured in samples of morning urine specimens. Children with VUR or renal defects detected by voiding cystourethrography (VCUG) and DMSA renal scan were investigated. Results : Microalbumin/Cr ratio of spot urine was significantly increased in group III compared group I ($42.3{\pm}27.2\;mg/gCr$ vs $25.2{\pm}10.9\;mg/gCr$, P<0.05). NAG/Cr ratio of spot urine was significantly increased in group II compared group I ($3.70{\pm}23.4\;mg/gCr$ vs $18.7{\pm}12.7\;mg/gCr$, P<0.05). There was no statistically significant difference of ${\beta}_2$ MG/Cr ratio among three groups. Conclusion : Urinary microalbumin excretion of morning urine sample may be a simple and reliable clinical indicators for early identification of renal damage in children with VUR and renal defects. Urinary microalbumin excretion may be useful marker to predict the the severity of VUR.

The objectives of this study was to analyze the major causes of decreasing utilization rate of health care institutios in pilot-project area of regional medical insurance, Kwang-hwa and Kun-wi country. After the implementation of medical insurance, utilization rate of health institutions turned out' to be lower than it was estimated, when the pilot-project of regional medical insurance was planned. It might be due to changes in inhabitant's behavioral attitude toward medical insurance. So this study was made to find measures for financial stability by increasing utilization rate of health care institutions and to be available for basic demand-supply program of medical care. The hypothesis of this study was as follows; First. there is difference in understanding health care institutions between Kun-wi and Kwang-hwa. Second. respondesnts of inquiry survey have exact knowledge of their past experience of treatment taken prior to enforcement of medical insurance, Questionaire survey was made as to each 700 household among total 11, 884 households in Kun-wi and 20,919 households in Kwang-hwa. In case of Kun-wi, 70% of inquired households (491) gave their answers. In Kwang-hwa, the number was 560 households (80% of inquireds). Dollected data was processed and analyzed by way of using SPSS batch system. To evaluate facto rs distribution aspects of data and to make comparison between two area, percentage and $X^2$ distribution were applied. The results were as follows; L The utilization rate of health care institutions in Kun-wi and Kwang-hwa was lower than it was estimated. when pilot-project of medical insurance was planned. 2. Prior to the implementation of medical insurance. inhabitants in two area chose the medical institutions considering such factors. First was medical care fee cheap. second in habitant's residence, Third was the institutions conveniently easy of access. 3. After the implementation of medical insurance. 26.1% of inqurieds in Kun-wi and 41.6% in Kwang-hwa, changed medical institutions. In case of Kwn-wi, from health care institution (p 0.05), and in case of Kwang-hwa, vice versa, from general medical institutions to health care institutions. 4. Evaluation by factors were made such as follows. Inquired gave high marks to following facts: In case of Kun-wi, general medical institutions were difficult of access and relation between patients: was not friendly, but burden of medical expenditure was light. Effects of treatment and facilities was good. In case of Kwang-hwa, inquired gave high evaluation marks to the follow ing facts; facilities of medical institutions was not good, but the burden of medical expenditure was light. 5. After the implementation of medical insurance, the services was evaluated as good, but inquired hopec for lessening the burden of medical expenditure. 6. In case of exact understanding of cost-sharing, the evaluation rate in Kwang-hwa was higher than that of Kun-wi (p < 0.005). And positive attitude toward necessity of medical insurance was also good in Kwang-hwa (p < 0.05). 7. In case of inquired's attitude toward medical institutions, Kwang-hwa showed positive response (p < 0.05) 8. In the case of comparison between general medical institution and health care institution, two area showed similar positive response; medical manpower, facilities of medical institutions and effest: of treatement was good. 9. In comprehensive evaluation of benefit-service; the general medical institution's positiveness was higher than that of health care institutions in Kun-wi. But in Kwang-hwa vice-versa. 10. If the medical expenditure of general medical institution and health care institutions was equal 77% of inquireds in Kun-wi and 59.1% in Kwang-hwa answered that they chose general medical insurance. Considering results above mentioned, the conclusion of this study was made as follows. 1. In Kwang-hwa county, where the understanding of health care institutions's was good, the utilization's of health care institutions was shown high. Therefore, in case of Kwang-hwa, betterment: should be made to induce increasing utilization rate for negative factors of health care institutions. 2. In case of Kun-wi, where the understanding of health care institutions was on the decrease, measures for changing such negative factors should be taken by way of strengthening public relations. And cases of Kwang-hwa should also be studied. 3. On the side of financial stabilization and establishing health care delivery system, primary health care should be available. Therefore, the major cause of inhabitant's avoiding health care institutions should be known. And measures for activating that institutions have to be taken. So, the facilities of health care institution have to be improved up to the level of clinic. And supportive measures for securing equipment and improving health care services should also be taken. It is necessary that strategy for public relations should be employed with policy considerations and supports.

Purpose: The uptake of $^{99m}Tc$-MIBI increases in the parathyroid adenoma, hyperplasia, and carcinoma. The purpose of this study is to evaluate and compare the results of the biopsy with quantitative analysis results in the localized parathyroid lesions (adenoma, hyperplasia, and carcinoma). Materials and Methods: From April 2002 to January 2009, double-phase $^{99m}Tc$-MIBI parathyroid scan (early 15 min, delayed 2 hrs) was performed after injection of 750 MBq of $^{99m}Tc$-MIBI in 27 diagnosed parathyroid patients (adenoma:15, hyperplasia:4, carcinoma:8). For quantitative analysis, early, delayed lesion to non-lesion ratios (L/NLs), washout rate (%, WR) and vertical axis were calculated. Results: In early images, lesion to non-lesion ratios were $1.53{\pm}0.41$ (adenoma), $1.38{\pm}0.27$ (hyperplasia) and $1.45{\pm}0.64$ (carcinoma). In delayed images, lesion to non-lesion ratios were $1.56{\pm}0.43$ (adenoma), $1.33{\pm}0.10$ (hyperplasia), $1.83{\pm}0.79$ (carcinoma). In vertical axis, the sizes were $2.11{\pm}0.67$ (adenoma), $2.23{\pm}0.75$ (hyperplasia) and $2.20{\pm}0.97$ (carcinoma). There was no statistical difference between lesion to non-lesion ratios and the size of vertical axis (p>0.05). However, washout rates were $31.59{\pm}13.97$ (adenoma), $37.8{\pm}5.69$ (hyperplasia), $17.73{\pm}11.02$ (carcinoma). As a result, there was a significant difference statistically between and that of carcinoma (p<0.05, p=0.028 by Kruskal-willis statistic, Dunn's Multiple comparison test SPSS Ver 12.0). Conclusions: There was no statistical difference between the lesion to non-lesion ratios and the size of vertical axis. However, there was a significant difference statistically between WR of hyperplasia and that of carcinoma.

Purpose: Detection of TSH-binding inhibitor immunoglobulin (TBII) in patients with hyperthyroidism is an important result of Graves' disease (GD) and hyperthyroidism treatment. This has been made out an inspection by commercial radio-receptor assays. To increase the sensitivity and the specificity of the assay, many results of the assay were reported. In this study we evaluated the clinical usetulness of TBII assays by the Comparative method. Material and Methods: We were measured by using healthy control group (n=30, male=20, female=10) of Seoul National University Hospital Healthcare System Gangnam Center from January to March in 2009. Similarly, We were measured by using hyperthyroid (TSH<$0.05\;{\mu}IU/mL$, FT4>1.80 ng/dL) experimental group (n=58, male=14, female=44) of division of endocrinology and metabolism department of internal medicine Seoul National University Hospital from January to March in 2009. We made a comparative study of each two assays from the first generation to the third generation. We were used of TSAb assay as a measurement of GD diagnostic technique. Results: The specificity of healthy control group was 100% according to the generation. (Specificity=100%, n=30) The sensitivity of hyperthyroid experimental group were the first generation RSR<%> (79.3%, n=58), RSR (51.7%, n=58), the second generation RSR-CT (93.1%, n=58), BRAHMSCT (98.3%, n=58), the third generation ELISA (94.6%, n=56), ECLIA (97.7%, n=58) and TS-Ab<%> (93.5%, n=46). Conclusion: We were used of TSAb assay as a measurement of GD diagnostic technique, The result of data showed a high correlation between the third generation TBII assay and the second generation TBII assay ($R^2$=0.923). Instead of the first generation assay, the second generation assay can be more useful in clincal diagnosis.

Purpose: World Health Organization (WHO) have suggested that an individual's 10-year absolute fracture risk is more reliable than Bone Mineral Density (BMD) measurement as the predictor of osteoporotic fracture. In 2008, Fracture Risk Assessment Tool ($FRAX^{TM}$) was developed by WHO to evaluate fracture risk of patients based on individual's clinical risk factors. The purpose of this study is to offer the comparative analysis of the existing GE prodigy and $FRAX^{TM}$ Tool in Absolute Fracture Risk Assessment Tool. Materials and Methods: 201 women ($55{\pm}3.5$ years) underwent femoral neck BMD measurement using GE Prodigy. The 10-year probability (%) of hip fracture (or a major osteoporosis-related fracture) was estimated using T-scores of GE prodigy and $FRAX^{TM}$. We made a comparative analysis of these data using SPSS (Ver.12). Results: There was a significant difference statistically between T-score ($-0.52{\pm}0.97$) of GE prodigy and T-score ($-1.45{\pm}0.81$) of $FRAX^{TM}$ (r=0.977, p=0.000). Also, there was a significant difference statistically between a major osteoporosis- related fracture ($9.15{\pm}3.71$) of GE prodigy and a major osteoporosis-related fracture ($4.87{\pm}1.51$) of $FRAX^{TM}$ (r=0.909, p=0.000). Moreover, a statistically significant difference was found in the 10-year probability of hip fracture of GE prodigy ($1.56{\pm}1.48$) and of hip fracture ($0.53{\pm}0.61$) of $FRAX^{TM}$ (r=0.905, p=0.000). Conclusions: There was a significant difference statistically between GE prodigy and $FRAX^{TM}$ Tool in Absolute Fracture Risk Assessment Tool. Especially, T-score, a major osteoporosis-related fracture and the 10-year probability of hip fracture that were estimated using GE prodigy tended to show the higher results than one evaluated by $FRAX^{TM}$ Tool. In conclusion, $FRAX^{TM}$ Tool may provide a better tool. The application of $FRAX^{TM}$ Tool as a fracture predictor remains to be clarified.
