Chronic granulomatous disease (CGD) is one of congenital immunodeficient disease and a rare X-linked or autosomal recessive disease characterized by recurrent life- threatening infections and granuloma formation. We observed clinical features, laboratory findings and genetic subgroups of 33 children who were diagnosed with chronic granulomatous disease in the Department of Pediatrics, Seoul National University Children's Hospital. There were 23 males and 10 females. Activated NBT test of all patients revealed 0% positive cell and mothers of 15 patients had 25%- 75% normal neutrophils in the activated NBT test. According to the result of activated NBT test and family history, the ratio of X-linked and autosomal recessive inheritance was 2:3. There was a significant difference for the age at onset of the first infection in the different genetic subgroups. The X-linked group had the mean onset at 1.98 months of age and autosomal recessive group had a mean onset as late as 3.82 months (p<0.05). The most common type of the first infection was lymphadenopathies (41%) and other infections were skin pustules, fever, perianal abscess, pneumonia and chronic diarrhea. However, the age at diagnosis was not significant in the different genetic subgroups. Lymphadenitis (27%) was the most common infection, and pneumonia, gastrointestinal tract infection, skin infection were also common. The most common infectious agent was Candida sp. (5%) and other microorganisms involved were BCG, coagulase-negative staphylococcus, S. aureus, K/ebsiella pneumoniae, Aspergi/lus sp., and Enterococcus faecium. Chronic condition associated with CGD were hepatomegaly (59%), splenomegaly, and anemia of chronic disease, underweight, and lymphadenopathy. The leukocyte count of patients at diagnosis was within normal limit except in three patients and leukopenia was not observed in any of the patients. The humoral and cellular immunity and complement system were normal, but the level of Ig E in four patients was elevated. Early diagnosis of CGD can be made by suspicion if there are lymphadenitis after BCG vaccination and recurrent pyogenic infections under the first year of age. Though progression in the treatment of CGD, like gene therapy, is concerned, genetic counseling and prenatal diagnosis by carrier detection and molecular genetic analysis is thought to be necessary.

This study investigated the influence of IRM on marginal microleakage of 5th generation adhesives. Class V cavities with gingival margins in dentin were prepared on both buccal and lingual surfaces of 60 extracted human molar teeth. Prepared teeth were randomly divided into six groups. Group 1 and 4 received no temporary restoration with IRM. Group 2 and 5 were covered with IRM mixed at P/L ratio(10g/1g). Group 3 and 6 were covered with IRM mixed at P/L ratio(10g/2g). The temporary restorations were removed mechanically with an ultrasonic scaler after one-week storage in distilled water. The cavities were restored using one of two adhesives and composites; Single Bond/Filtek Z 250(Group 1, 2 and 3), UniFil Bond/UniFil F(Group 4, 5 and 6). Following one day storage in distilled water, the restored teeth were thermocycled for 500 cycles(between 5degrees C and 55degrees C) and immersed in 2% methylene blue for dye penetration testing. The results were analysed using Kruskal-Wallis Test, Mann-Whitney and Wilcoxon signed ranked test at a significance level of 0.05. The results of this study were as follows: 1. Ranking of mean microleakage scores at the enamel margins was Group 10.05). 4. At the dentin margins, the microleakage of the group not pretreated with IRM was lower than that of the group pretreated with IRM. And the microleakage of UniFil Bond was lower than that of Single Bond. 5. Compared with microleakages between the enamel and dentin margins of each groups, Group 1, 2, 3, 4, 5 and 6 at dentin margin were higher microleakage than those at enamel margin. There were significant difference between enamel and dentin microleakage of Group 2 and 3(p<0.05).

To differentiate the postoperative changes from the recurrence of tumor and to evaluate MR imaging of early postoperative leptomeningeal seeding in medulloblastoma, We have retrospectively analysed 34 cases of MR images of 17 patients who were confirmed as medulloblastoma by histopathology. Noncontrast and postcontrast T1 weighted MR images were obtained in all patients. In 11 patients follow-up MR was done more than once (average:1.5 times) and average interval of MR imaging was 6 months. The timing of 34 MR images was as follow: 6 case within 2 months, 9 cases between 2 months and 1 year, 19 cases more than 1 year after surgery respectively. MR images within 2 month after surgery revealed contrast enhancement at operation site and adjacent meninges, hemorrhage, residual tumor. In patients who had no evidence of tumor recurrence, these early postoperative changes were markedly decreased within 6 month after sugery. MR images obtained more than 1 year after sugery showed no abnormal contrast enhancement or mild focal dural enhancement at operation site. Diffuse moderate dural enhancement was noted in one patient who had the history of post-surgical subdural hemorrhage. In six patients with tumor recurrences which were detected from as early as 9months to 6 years after surgery, the findings of recurrence included leptomeningeal enhancement of brain stem and cerebellar surface at early stage, variable sized enhancing leptomeningeal nodules, linear or irregular sulcus obliterating enhancing lesions, enhancing mass at primary or metastatic site. We have concluded that leptomeningeal enhancement detected after 6 months of surgery is an important MR finding suggesting the possibility of tumor recurrence. Small nodular and linear enhancement of leptomeninges at brainstem or cerebellar surface is considered as the early manifestation of intracranial tumor seeding.

STATEMENT OF PROBLEM: Factors affecting patients' decision-making for dental prosthetic treatment should be examined in terms of understanding improving patients' oral health. PURPOSE: The main purpose of this dissertation was to investigate patients' dental prosthetic treatment and factors affecting patients' decision-making for dental prosthesis treatment in Deagu and Gyungbook areas. MATERIAL AND METHODS: This study was based on the preliminary survey of dental patients conducted from July 1 to August 31 in 2006. A total of 700 questionnaires had been distributed and 640 were collected. 629 questionnaires were used for the statistical analysis. Descriptive and inferential statistics, such as frequencies, cross tabulation analysis, correlation analysis, logistic regression analysis, and multiple regression analysis were introduced. In the multiple regression analysis and logistic regression analysis, twenty-two independent variables were employed to explore the factors which have impacts on decision-making and satisfaction. RESULTS: The results of this dissertation are as follows: Logistic regression analysis turned out that monthly income, age, degree of expectation, marital status, and employer-insured policy of national insurance statistically increased the odds of decision-making of dental prosthesis treatment. But educational attainment decreased the odds ratio of the decision-making of dental prosthesis treatment. However, the rest independent variables do not have statistically significant impacts on the decision-making of dental prosthesis treatment CONCLUSION: Among independent variables, marital status had the most significant influence on the decision making of dental prosthesis treatment. Finally, suggestions for the future study and policy implications to improve satisfaction of the patients' dental prosthetic treatment were discussed.

Ureteroneocystostomy may be used in the cases of the vesicoureteral reflux, reteral stricture, ectopic ureteral orifice, ureterovaginal fistula and damage on the lower part of ureter during operation. 0nce ureteroneocystostomy is decided on every effort should be made to perform an antireflux procedure. The results of ureteroneocystostomy have improved consistently during last 20 years, but cases of reflux and postoperative ureterovesical obstruction are still encountered. A clinical study was made on 8 cases who had been performed ureteroneocystostomy at the Department of Urology, Jeonbug National University, Medical School from January 1978 to February 1980. The results were as follows` 1. The age of the patients ranged from 14 to 56 years, most common in fifth decade. The sex ratio was 3:1, with female 6 and male 2. 2. Underlying diseases for ureteroneocystostomy were ureteral stricture, megaloureter, ectopic ureteral orifice and vesicoureteral reflux. 3. 3 Ureters were performed with the method of paquin procedure, 2 ureters with the combination of paquin with Psoas-bladder hitch procedure, one ureter with the combination of Boari flap with Psoas-bladder hitch procedure, one ureter with Politano-Leadbetter procedure and one ureter with Lich procedure 4. Relatively good results of ureteral reimplantation were obtained in distal ureteral stricture, ectopic ureteral orifice and vesicoureteral reflux, except one case of megaloureter in which nephroureterectomy was performed later due to adynamic ureter 5. Complications were followed as persistent pyuria in one case and urine leakage in one case, and nephroureterectomy for adynamic ureter in one case.

Neurilemmomas of the extremities are nerve sheath tumors involving peripheral nerves of the extremities. We analyzed MR images of 16 surgically proved tumors in 12 patients and compared the MR images with gross pathologic specimens in two tumors (2/16). Spin echo T1-weighted images were obtained in all the patients but T2-weighted images were obtained in six patients with a gradient echo technique. Gadolinium dimeglumine enhanced T1-weighted images were obtained in 11 patients (15/16). Signal on T1-weighted images was iso or slightly higher than that of the adjacent muscles. Signal on T2-weighted images ranged from homogeneous high to heterogeneous. After Gadolinium injection, all the 15 tumors showed enhancement. Small sized tumors were enhanced homogeneously but there was a tendency tobe enhanced heterogeneously to the central portion with peripheral rim enhancement as the size of the tumors increased. Pathologically, the enhanced portion was correlated the with solid protion was correlated the with solid portion of the tumors. Also encapsulation of the mass (12/16), suspended nerve strings (9/16) and bony erosion (1/16) were detected. MR characteristics of neurilemmoma include heterogeniety on enhanced T1 and T2 weighted images, encapsulation, and suspended nerve strings. Signal heterogeneity on enhanced T1 and T2 weignted images may be attributed to the variable cellularity, cystic changes, vascularity and focal hemorrhage of the tumors.

A clinical observation was made on the injuries of genitourinary tract of the in-patient during the period from January, 1978 to March, 1982. The results were as follows: 1. Of 1457 cases hospitalized, 148 cases were injury of genitourinary tract, giving a ratio of 10.1%. 2. The most prevalent age was 5th decade for 26.6% and the next was 3rd decade for 24.3%. The sex ratio, male to female was 5.2:1. 3. Fall down was the most fequent cause of the injury (34.6%) and the next was traffic accident (30.1%). In detail, traffic accident was the most frequent cause of renal injury. Fall down was the most frequent cause of bladder and urethral injury. The kick and blow was most frequent cause of external genitalia. The most ureteral injury was introgenic. 4. The urethra was involved most frequently in 37.9%, the kidney in 24.8%, the bladder in 18.3%, the externalgenitalia in 16.3% and the ureter in 2.7%. 5. 23 of 58 urethral injuries (39.7%) and 8 of 28 bladder injuries (28.6%) were accompanied with pelvic bone fracture. 6. Operation was performed in 15 cases of 38 renal injuries(Nephrectomy 10, I & D 3, renorraphy 1, omentalpatch graft 1).
