Purpose: The purpose of this study was to assess the result of arthroscopic treatment in septic knee arthritis and evaluate the prognostic factor over 50 years old. Materials and Methods: Fifty-two patients were treated by arthroscope for septic knee arthritis from January, 2002 to August, 2005. The mean follow-up period was 27.5months. We assessed Lysholm score as functional result, CRP normalized period as laboratory result, and knee range of motion as clinical result. We evaluated patient's age, underlying disease, causative organism, previous knee status (Kellgren stage), clinical status of septic arthritis (G$\ddot{a}$chter stage) and history of intra-articular injection as prognostic factor. Results: Mean Lysholm score was improved from 40.7 to 67.1. And the mean CRP normalized period was 38.7days. At last follow-up, almost patient (92%) were recovered to prior knee full range of motion and 45 patient (74%) were completely cured by one stage operation. The microorganism isolated were MSSA (n=13), MSSE (n=3), MRSA/MRSE (n=4),no microorganism (n=27) and others (n=5). In Lysholm score, young age (42.8(preop.)$\rightarrow$83.5(postop.)), Kellgren stage 0 ($45.5{\rightarrow}84.2$), G$\ddot{a}$chter stage I ($39.3{\rightarrow}73.1$) and no microorganism (442.1{\rightarrow}72.6$) were more increased than old age (439.3{\rightarrow}61.7$), Kellgren IV ($28.3{\rightarrow}43.7$), G$\ddot{a}$chter stage IV ($40.2{\rightarrow}67.1$) and MRSA/MRSE ($40{\rightarrow}58.75$). In case of old age (42.3days), G$\ddot{a}$chter stage IV (55.5), Kellgren stage IV(43.7), DM patient (42.1) and intra-articular injection history (52.1), the CRP titer normalized period was longer than mean period. MRSA/MRSE(n=3,75%) were not normalized in CRP titer at last follow-up. Conclusion: Arthroscopic treatment of septic knee would be an effective and satisfactory procedure. Age, previous knee status (Kellgren stage), underlying disease (DM), intra-articular injection history, microorganism and Ga¨chter stage effect end result outcome.

Purpose: The lower extremity edema (LEE) is a common distressful symptom in advanced cancer patients and is hard to manage. We analyze the characteristics of LEE in patients with advanced cancer to provide the basic information of causes and adequate management. Methods: Physical examination, assessment of the location and severity of edema, blood chemistry (albumin, creatinine), Doppler Sono for patients with suspecting deep vein thrombosis (DVT), and abdomen CT scan for patient with suspecting lymph edema were performed. Severity of edema was classified according to NCI lymph edema scaling and improvement was defined as lowering at least 1 grade of edema after management. Results: Among 154 patient who had been admitted to Hospice Ward from Mar 2003 to Jan 2004, 33 had LEE, and 6 had both upper extremity edema and LEE except generalized edema. Their underlying cancers were stomach (7), lung (6), biliary tract (5), liver (5), colorectal (5), pancreas (2), and others (9). There were 12 patient with grade I, 20 patients with grade II, and 7 patients with grade III edema. The causes were hypoalbuminemia (11), lymph edema (10), DVT (7), obstruction of inferior vena cava (IVC) or portal vein (6), and dependent edema (5). The common managements were including leg elevation and diuretics. Elastic stocking was applied for patients with DVT and leg massage and pneumatic compression was used for lymph edema. The 2/3 patients were improved after management. Conclusion: The incidence of LEE in terminal cancer pts was high (25.3%) and their causes were variable including lymph edema, DVT, hypoalbuminemia and dependent edema. Active noninvasive management according to causes could result in good palliation.

Purpose: The purpose of this study was to identify the effectiveness of multimodal pain control method in an early phase after arthroscopic rotator cuff repair, under interscalene brachial plexus block, this study was performed. Materials and Methods: The study was progressed with the 80 cases of arthroscopic rotator cuff repair. Interscalene brachial plexus block was used to all of the 80 cases and patients were divided into 2 groups. Group A consisted of patients injected with bupivacaine, through subacromial space catheter after surgery, and group B consisted of patients with additional method of multimodal pain control using oral opioids, acetaminophen-tramadol complex and selective COX2 inhibitor. Subacromial cathter was removed after injection in both groups. The pain during the day time and night time was compared on the operation day, postoperative 1st, 2nd, 3rd day and 2nd weeks, and it was measured with VAS (visual analogue scale) score. Additionally, the number of ketolorac injection and side-effect related to analgesics was compared between the 2 groups. Results : The mean VAS score of night time on the operation day and day/night time pain of the 1st, 2nd, 3rd day and 2nd weeks was 7.4, 7.0/6.8, 4.5/5.2, 4.8/5.0, 2.2/2.7 on group A and 6.5, 4.3/5.4, 3.2/4.3, 3.0/4.1, 2.4/2.5 on group B, respectively. Significant difference was observed in the night pain on the operation day, 1st, 2nd, 3rd day time and 1st night time pain (p<.05). The average number of ketololac injection was 1.1 and 0.5 in each group, and there was no difference in the frequency of side effects. Conclusion: Multimodal pain control method, after arthroscopic rotator cuff repair, showed an effective early pain control and improved patients' satisfaction.

Purpose : Renal transplantation which allows children normal growth and development and a return to normal life. is now proven to be the best modality for children with ESRD Up to Recently, the number of renal transplantations in Asia has rapidly increased and the outcome has also improved. This investigation was planned to estimate the current status of pediatric renal transplantation in Asia and to find the keys for better improvement of outcome in pediatric renal allograft in Asian countries. Material and methods : The participating countries and institutions for this investigation were China, Hong Kong, India, Indonesia, Japan, Malaysia, Pakistan, Philippines, Singapore, Thailand, Korea, KSPN (Korean Society of Pediatric Nephrology), KONOS (Korean Network for Organ Sharing). Results : Many countries in Asia still do not have a well organized nation wide renal transplantation registration system independently in the pediatric field. So it's very difficult to evaluate the real state of pediatric transplantation among Asian countries. According to the estimation with fragmented data from each countries, in the front running countries of pediatric renal transplantation in Asia, about 40 or more transplants were performed in each country per year and the five year actuarial renal allograft survival was around 80% which is similar to that of western countries. But there were large gaps among the behind groups. Conclusion : Vigorous attempts to perform renal transplantation for children especially younger than 5 years old would be encouraged as well as organ donation from brain dead donor and non heart beating cadaveric donor also should be activated to cope effectively with the shortage of living donor supply. Large number of recent reports shows the favorable outcome of pre-emptive renal transplantation, we should make more efforts toward pre-emptive renal transplantation. First of all, in order to improve the outcome and to narrow the gap between Asian countries in pediatric renal transplantation, effective and continuous efforts to establish nationwide pediatric renal transplantation registration program as well as official, nation-to-nation data sharing program should be needed.

Purpose : Vesicoureteral reflux (VUR), which can result in renal failure in children, is expected to resolve spontaneously in mild cases, but severe cases require surgical correction, posing dilemma in deciding the right measures in some cases. Therefore, to delineate the factors affecting spontaneous resolution of VUR and to apply them in assessing the prognosis, we reviewed the patients with VUR who had been treated medically. Patients and Methods : 32 children (49 renal units) with reflux who had been admitted during the 5-year period from Jan '92 to Dec '96 were classified into 4 groups (Resolved, Improved, Unchanged, and Worsened) and analyzed. Results : 1) 25 were boys and 7 girls. The age at diagnosis ranged from 13 days to 9 years (mean $24.6{\pm}11.4$ mo) 2) Among 49 refluxing ureters, 4 were below 1 me of age,21 between 1 me to 1 yr, 16 between 1 yr to 6 yr, 8 beyond 6 yr. Two belonged to Grade I, 16 to Crade II, 17 to Grade III, 12 to Grade IV, and 2 to Grade V. 3) Spontaneous resolution rates of reflux were 100, 81, 47, 8, 0$\%$ for each Grade, respectively. Resolution plus improvement rates in Grade III and IV were 71 and $50\%$, each. 4) Resolution rates in relation to the age at diagnosis were $100\%$ for below 1 mo, $48\%$ between 1 mo to 1 yr, $56\%$ between 1 to 6 yr, and $13\%$ beyond 6 yr. 5) Of 15 unilateral refluxing ureters, 14 ($93\%$) resulted in resolution. Of 34 bilateral refluxing ureters, 11 ($32\%$) resolved spontaneously 6) Resolution occurred within 1 year in 20 units of 24 renal units in regular follow-up. Conclusion: The lower the initial grade and the younger the patient, the sooner the reflux resolved. Resolution was better when VUR was unilateral than bilateral. Long-term regular follow-up is essential because even the cases falling in Grades III and IV have high rates of spontaneous resolution and improvement with medical treatment.

Purpose : To find and solve the common problems of peritoneal dialysis(PD) by analysing the clinical data of pediatric PD performed in Korea. Methods : 264 cases of CAPD and acute PD had been performed from Nov.1987 to Oct. 1997 in 17 institutions of pediatric nephrology in Korea. Results : CAPD was performed in 114 cases. The mean age of the patients was $10.5{\pm}6.6$ years and male to female ratio was 1.4:1. The original renal diseases of ESRD were proven in 92 cases($80\%$). The common renal disease of ESRD were FSGS($17\%$), reflux nephropathy ($11\%$), chronic glomerulonephritis($9.6\%$). Mean duration of CAPD was $20{\pm}16.9$ months. Peritonitis was the most common complication and incidence was one episode/18.2 patient-months. Other complications were exit site infection in 10 cases, obstruction in 7 cases, leakage of dialysate in 6 cases. The most common etiologic organism of peritonitis was staphylococcus aureus and the next was staphylococcus coagulase(-). Acute PD was performed in 150 cases. Most common underlying causes were congenital heart disease, hemolytic uremic syndrome, sepsis and dehydration. The mean duration was $10.3{\pm}11.3$ days. The most common complication was peritonitis($20.6\%$). The most common etiologic organism was staphylococcus aureus and coagulase(-), acinetobactor and pseudomonas. Conclusion : Reflux nephropathy should be emphasized in early diagnosis and treatment to prevent ESRD. Incidence of congenital anomaly($7\%$) as a original disease of ESRD was relatively low in Korea. Growth status was not significantly improved after CAPD. In acute PD, the incidence of peritonitis was rapidly increased at 2weeks after beginning of dialysis.

Purpose : PET/CT performed CT-based attenuation correction generates the beam hardening artifact by metallic implant. The attenuation correction causes over or underestimate of the area adjacent to metallic hip prosthetic material and change of $^{18}F$-FDG uptake. Also, the image quality and the diagnosability on genitourinary disease are reduced. Therefore, this study will evaluate the usefulness of MAR (Metal Artifact Reduction) algorithm method to improve the image quality on PET/CT. Materials and Methods : PET/CT was performed by fixing hip prosthesis in SPECT/PET phantom. In PET images with and Without MAR algorithm, the Bright streak, Dark streak, Metal region and Background area that appeared on CT were confirmed, and the change of each SUV (standardized uptake value) was analyzed. Also, in 15 patients who underwent total hip arthroplasty, each MAR algorithm and Without MAR algorithm and non attenuation correction was evaluated. Results : In PET image Without MAR algorithm, SUV of Bright streak region was $0.98{\pm}0.48$ g/ml; Dark streak region was $0.88{\pm}0.02$ g/ml; Metal region was $0.24{\pm}0.16$ g/ml, Background area was $0.91{\pm}0.18$ g/ml. In SUV of PET image with MAR algorithm, Bright streak region was $0.88{\pm}0.49$ g/ml, Dark streak region was $0.63{\pm}0.21$ g/ml, Metal region was $0.06{\pm}0.07$ g/ml, Background was $0.90{\pm}0.02$ g/ml. SUV generally decreased when applying MAR algorithm. In PET image Without MAR algorithm, SUVs of Bright region were higher than those measured in the Background, and it was false positive uptake. But, in PET image with MAR algorithm, SUVs of Bright region were similar to the Background, and false positive uptake disappeared. Conclusion : MAR algorithm could reduce an increase of $^{18}F$-FDG uptake due to attenuation correction in the hip surrounding tissue. However, decrease of SUV in Dark streak region should be considered in the future. Therefore, this study propose that the diagnostic accuracy can be improved in genitourinary diseases adjacent to metallic hip prosthesis, if provided PET images with and Without MAR algorithm, and non attenuation correction images at the same time.

Purpose: Early diagnosis of breast is of the utmost importance to improve prognosis. We have a limitation for mammography and sonography detecting small cancer. Clinical importance of Breast Specific Gamma Imaging (BSGI) has improved for that reason. So We studied performance evaluation test of count rate and resolution with high sensitivity to the low dose of BSGI. Materials and Methods: BSGI of Dilon 6800, point source of $^{99m}Tc$ from 1.85~148 MBq (0.05~4 mCi) at the intervals of 1.85~37 MBq (0.05~1 mCi) was used for the test. Performance evaluation method was performed for measuring deadtime for choosing at the 5 different point in the useful field of view (UFOV), acquired image for 60 seconds. Compared with reference of clinical uptake distribution of breast, activity increased according to the distance change 10, 20, 30, 40, 50 mm in the useful field of view. Results: Counting curve increased according to the activity from 1.85 MBq (0.05 mCi) to the 74 MBq (2 mCi), and it change flat shape over 74 MBq (2 mCi). The variation of the full width of half maximum (FWHM) to the distance is 4.05, 4.73, 5.77, 6.90, 8.00, 9.32 mm in 1.85 MBq (0.05 mCi), 4.30, 4.80, 5.90, 7.00, 8.10, 9.07 mm in 3.7 MBq (0.1 mCi), 4.90, 5.60, 6.20, 7.20, 8.20, 9.10 mm in 5.55 MBq (0.15 mCi), 5.30, 6.10, 6.60, 7.00, 7.90, 8.70 mm in 7.40 MBq (0.2 mCi). Conclusion: Distortions of image would be acquired because of the deadtime in BSGI. We found out the fact that specification of $^{99m}Tc$ reaction under 74 MBq (2 mCi) for BSGI. Second, FWHM distribution change from varied distance from the detector, clearly distinguished the location of the lesion.
