Endoscopic metal stent insertion has been widely performed to palliatively treat gastrointestinal (GI) tract obstruction in patients with cancer. The use of metal stents for benign strictures of the GI tract is increasing due to the low risk of major complications other than stent migration. The incidence of acute pancreatitis after placing a GI tract metal stent is rare. Herein, we report a case of acute pancreatitis caused by a covered metal stent that was initially inserted for a benign stricture of a gastroduodenal anastomosis that developed after the operation, then distally migrated, bent into a U-shape, and impacted into the second portion of the duodenum in a 56-year-old female who underwent a Billroth-I gastrectomy due to gastric cancer.

PURPOSE: Improved survival of patients with childhood acute lymphoblastic leukemia (ALL) has drawn attention to the potential for late consequences of previous treatments among survivors, including metabolic syndrome. In this study, we evaluated changes in 3 parameters, namely, random blood glucose, body mass index (BMI), and Z score for BMI (Z-BMI), in children with ALL during chemotherapy and after completion of treatment. METHODS: Patients newly diagnosed with ALL from January, 2005 to December, 2008 at Saint Mary's Hospital, The Catholic University of Korea, who completed treatment with chemotherapy only were included (n=107). Random glucose, BMI, and Z-BMI were recorded at 5 intervals: at diagnosis, before maintenance treatment, at completion of maintenance treatment, and 6 and 12 months after completion of maintenance treatment. Similar analyses were conducted on 2 subcohorts based on ALL risk groups. RESULTS: For random glucose, a paired comparison showed significantly lower levels at 12 months post-treatment compared to those at initial diagnosis (P<0.001) and before maintenance (P<0.001). The Z-BMI score was significantly higher before maintenance than at diagnosis (P<0.001), but decreased significantly at the end of treatment (P<0.001) and remained low at 6 months (P<0.001) and 12 months (P<0.001) post-treatment. Similar results were obtained upon analysis of risk group-based subcohorts. CONCLUSION: For a cohort of ALL patients treated without allogeneic transplantation or cranial irradiation, decrease in random glucose and Z-BMI after completion of chemotherapy does not indicate future glucose intolerance or obesity.

PURPOSE: Kidney size (KS) is used to diagnose the patients with renal disease. When the length of a kidney is measured under 9 cm, it is considered to indicate an irreversible disease. Because glomerular filtration rate (GFR) decreases with age, the normal range of KS in the elderly is indefinite. Therefore, we measured KS in adults older than 80 years old and investigated correlated factors. METHODS: One hundreds six adults (51 men, 55 women: mean age 83+/-0.3) without renal disease were included. Their serum creatinine (Scr) levels did not exceed 1.3 mg/dL, and the calculated GFR were over 60 mL/min/1.73m2. Abdominal ultrasonography were performed to all of them and their body indexes (BI) were measured. RESULTS: 1) The mean length of kidney was 9.9+/-0.07 cm. 2) KS in the early eighties was larger than that of adults over ninety. 3) KS showed negative correlations with age and Scr, but a positive correlation with body surface area . 4) The calculated GFR showed correlations with the surface areas of both kidney (BK) by C-G equation and with the size of BK by MDRD equation. 4) The GFR calculated by MDRD and C-G equation presented inverse correlations with Scr, but only MDRD equation showed a statistic significance. CONCLUSION:In the elderly, KS may be smaller than that of younger adults. Other factors such as either surface area or volume of BK and BI should be considered to estimate the individual KS to decide whether the size is within normal range.

The hemolytic uremic syndrome (HUS) is clinically characterized by microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure. The unique cause has not been determined but some bacteria such as E. coli was regarded as the causative agent of HUS in infant. A 30-year-old male patient was admitted due to acute abdomen. In operating field, the periappendiceal abscess was found, so the appendectomy with the drainage of abscess was performed. Initial hemoglobin level was 16.2g/dL but abruptly developed anemia (12.6g/dL) and thrombocytopenia (27000/mm3) was detected at hospital day 3. The urinary outflow was totally absent, the serum creatinine was 12.8mg/dL and the LDH was 3,650IU/L. The peripheral blood smear showed strong evidence of microangiopathic hemolysis. We performed total plasma exchange and hemodialysis under the diagnosis of HUS. The patient's renal function was markedly improved and the last creatinine was 1.9mg/dl. To our knowledge, this is the first report of HUS associated with periappendiceal abscess in Korea. We present a case and the review of literature.

Hemophagocytic syndrome is a rare syndrome characterized by fever, weight loss, profound pancytopenia, lymphadenopathy, hepatosplenomegaly and the pathologic finding of hemophagocytosis (phagocytosis by macrophages of erythrocytes, leukocytes, platelets, and their precursors) in bone marrow and other tissue. This syndrome can be associated with viral infections and lymphoid neoplasia, bacteria, fungus and drugs. Hyperproduction of cytokines, including interferon-gamma, tumor necrosis factor-alpha, may play a role in the pathogenesis of hemophagocytosis. Authors experienced a rare case of hemophagocytic syndrome associated with tuberculosis in a 40-year- old female who had undergone renal transplantation 12 years ago and received triple immunotherapy. After the beginning of antituberculosis therapy, the laboratory disturbances disappeared and clinical symptoms improved. Tuberculosis is a common infection in Korea. Therefore, we would like to recommend early bone marrow biopsy and antituberculosis therapy if fever of unknown origin, hepatosplenomegaly and pancytopenia in immunosupressive patients.

Clinical heterotopic liver transplantation(HLT) has been carried out in the several institutions since 1962. Recently, Rotterdam group reported a successful clinical series of HLT in spite of several negative viewpoints against orthotopic liver transplantation. Among the successful HLT cases till now, several occurrences of hepatocellular carcinoma in the native liver had been reported. In the current study, a thirty percent liver was transplanted heterotopically in the dimethylnitrosoamine(DMN)-induced cirrhotic rats and the feasibility of host-hepatectomy after regeneration of the graft was tested, and we are going to introduce the concept of host liver resection(HR) to the clinical auxiliary liver transplantation. Of the thirty syngeneic partial HLT with portal blood input only, 16 rats died following transplantation and three rats dies after HR. The DMN-induced cirrhotic liver specimen showed a microscopic finding of nodular cirrhosis with thick intralobular fibrous septa. Grafts examined at three posttransplant weeks appeared architecturally normal and well regenerated and the atrophied host livers were small hard showing micronodularity on the surface. Of all the animals examined, no host liver tissues were regrowing after one month following near total HR. We conclude that HLT can be performed in the clinically relevant cirrhotic rats and HR is feasible after graft regeneration and expect that this experimental model can be used for the study of cirrhosis and HLT.

PURPOSE:Preconditioning due to activation of AMPK might reduce ischemia-reperfusion (I/R) injury in the kidney, based on the key role of AMPK in preserving ATP. To evaluate this possibility, the effect of preconditioning with 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR), AMPK activator, before sustained ischemia was investigated. METHODS:Adult male Sprague-Dawley rats weighing approximately 220-250 g were used. To induce renal ischemia, a laparotomy was performed under ketamine and xylazine hydrochloride, and the blood supply to both kidneys was interrupted by placement of vessel clamps at the level of the renal pedicles. Reflow was initiated by removing the clamps. The following experimental groups were defined 1. Acute renal ischemia 0 sec, 10 min, 15 min, 2. AICAR treatment, 3. Sham group (S), 4. Ischemia/ Reperfusion group (I/R), 5. AICAR+I/R group (A+I/R), 6. AraA (Adenine-9-b-D-arabinofuranoside, an AMPK) inhibitor+AICAR+I/R group (AraA+A+I/R) RESULTS:There was only faint AMPK phosphorylation in the sham group. After 10 minutes of ischemia, or AICAR preconditioning however, Thr172 phosphorylation of AMPK was increased (p<0.05). The serum levels of BUN and creatinine were significantly decreased in AICAR preconditioning group (A+I/R). (128.0+/-7.33 mg/dL, 4.18+/-0.27 mg/dL vs. 90.2+/-11.13 mg/dL, 2.58+/-0.7 mg/dL, p<0.05), but these effects were attenuated by AMPK inhibitor, AraA (AraA+A+I/R group). In quantitative analysis of tubular injury, tubular injury score in AICAR preconditioning group significantly decreased (p<0.05). CONCLUSION:The AMPK activator AICAR has a protective effect against renal I/R injury.

We present a case of liposarcoma related with minimal change nephrotic syndrome. A 49-year-old woman was admitted due to generalized edema and a palpable mass at epigastric area. Her laboratory data were as follows : serum creatinine 0.6mg/dl, BUN 7mg/dl, serum total protein 3.6g/dl(albumin 0.6 g/dl) serum total cholesterol 299mg/dl, 24 hour-urine protein 5.1g. A CT scan of the abdomen revealed huge adult head sized mass(15X10X15cm) consisted with mixed pattern of well enhancing solid, cystic and fat portion which is located between the liver and the stomach. A kidney biopsy showed minimal change nephropathy. At explo-laparostomy the tumor was well differentiated liposarcoma. After operation and steroid therapy, her proteinuria and hypoalbuminemia were a little improved. And then radiation therapy(daily 180 cGy, 5 fx/wk, upto 5040cGy/28 fx/42 day) was done. Complete remission of liposarcoma was followed by regression of the nephrotic syndrome. After radiation therapy, her laboratory data were serum total protein 6.7g/dl (albumin 4.3g/dl), total cholesterol 170mg/dl, 24 hour-urine protein 0.3g. She has been maintained complete remission of the nephrotic syndrome by steroid maintenance dose.

BACKGROUND: The impact of hepatitis B or hepatitis C virus infection on renal transplantation outcome is controversial. The aim of this study is to assess the impact of hepatitis B and hepatitis C infection on kidney transplant over the long-term, 15 years and to compare infected patients with noninfected patients matched for factors possibly associated with graft and patient survival. METHODS: We analyzed 1,042 patients who underwent renal transplantation in period from March 1984 to Dec. 1998 including 107 with positive HBsAg (HBV(+) group), 81 with positive anti-HCV antibody (HCV(+) group) and 714 noninfected recipients (NBNC group). One hundred-forty patients who had not taken ani-HCV antibody screening test were excluded. The prevalence of chronic liver disease, the patient mortality, the patient survival rate and the graft survival rate were evaluated. RESULTS: The patient mortality during the period of follow-up was significantly higher in HBV(+) group(32.7%) than in HCV(+) group(9.9%) and NBNC group(8.4%). The cause of death related to liver desease was significantly higher in HBV(+) group(57.1%) than HCV(+) group(0%) and NBNC group(1.7%). Five year and 10 year graft survival rate were significantly lower in HBV(+) group(52.2 %, 39.2%) than in HCV(+) group(68.4%, 47.2%) and NBNC group(86.6%, 65.8%). Five year and 10 year patient survival rate of HBV(+) group(72.0%, 68.9%) was significantly lower than HCV(+) group(91.6%, 87.3%) and NBNC group(94.4%, 88.2%), but there was no significant difference in the patient survival rate between HCV(+) and NBNC group. CONCLUSION: Hepatitis B virus infection has a significant deleterious effect on the patient and graft survival of renal transplantation recipients. The poor survival rate was a result of the mortality from liver disorder. Hepatitis C virus infection also has a poor graft survival rate compared to NBNC group, but the patient survial rate is similar to NBNC group.

Goodpasture's syndrome is an autoimmune disease characterized by rapid progressive glomerulonephritis, alveolar hemorrhage and autoantibody to the NC1 domain of the alpha 3 chain of type IV collagen (anti-glomerular basement membrane antibody). It was common in Europe with peak incidence at third decades. However, Goodpasture's syndrome was reported only three cases in Korea. We reported a case of Goodpasture's syndrome in a 34 year old male. He admitted our hospital due to dyspnea and hemoptysis. We made diagnosis by detection of Anti-GBM Ab and biopsy of kidney. He was treated with hemodialysis, plasma exchanges and immunosuppressive agents. However, his renal function was not recovered. Currently, he is receiving regular hemodialysis.
