Bilateral renal cell carcinoma is very rare. In the past, bilateral renal cell carcinoma indicated a poor prognosis. But recently, aggressive operative intervention with nephron salvaging procedure can improve the survival of bilateral renal cell carcinoma. The conservative treatment of bilatera1 renal cell carcinoma depends on the size, the location and the stage of the tumor. Of several conservative surgical procedures, either enucleation or extracorporeal partial nephrectomy with autotransplantation were performed followed by radical nephrectomy in our cases. The advantages of an extracorporeal approach in such case include an optimum exposure, a bloodless surgical field, an ability to perform a more precise operation with maximum conservation of renal parenchyma, and a greater protection of the kidney from prolonged ischemia. Although this technique involves increased operative time with greater potential morbidity, we performed this procedure without much difficulties with the surgical skills culminated from renal transplantation.

PURPOSE: The residual intrahepatic stones with biliary strictures are difficult to remove percutaneously via T-tube tract after surgery in patients with recurrent pyogenic cholangitis. We evaluated the effectiveness of percutaneous balloon dilatation of benign biliary strictures. MATERIALS AND METHODS: The balloon dilatations with 6-12mm angioplasty balloon catheter and stone extractions were performed via a T-tube tract after surgical treatment in 15 patients with recurrent pyogenic cholangitis. The balloons were inflated for 3-4minutes under 5 atm. until disappearance of waist of the stricture site, from one to seven session. After balloon dilatation, residual stones were extracted with saline irrigation or stone basket. RESULTS: Among total 42 strictures, the balloon dilatation was succesful in 27 strictures(64.3%), partially successful in 12 strictures(28.6%), and failed in three strictures(7.1%). Single or central biliary strictures were dilated easily rather than multiple ductal strictures. Of 26 sites with residual intrahepatic stones, stone extraction was complete in 17 sites(65.4%), incomplete in seven sites(26.9%) due to impacted or large stone and acute ductal angulation, and failed in two sites(7.7%). CONCLUSION: Percutaneous balloon dilatation of benign biliary strictures is an effective procedure for extraction of residual intrahepatic stones associated with recurrent pyogenic cholangitis.

We report a one-day-old Korean boy with 2-Methylbutyryl-CoA dehydrogenase(2-MBCDase) deficiency detected by urine organic acid and acylglycine analysis, plasma acylcarnitine analysis and confirmed by enzyme assay and Western blot. The patient was born at 35 weeks and three days with oligohydroamnios and premature rupture of membrane for 31 hours, as a second child of healthy non-consanguineous parents. There was no significant family history and spontaneous abortion. He was admitted at NICU under ventilator care due to prematurity, respiratory difficulty, and decreased generalized muscle tone. During the first week of hospitalization, he presented with disseminated intravascular coagulation and sepsis. A grade IV intraventricular hemorrhage on brain sonography was observed on the 7th day after birth with seizure. The clinical course of aggravation and recovery was repeated for one month. In laboratory tests, blood C5-acylcarnitines(isovaleryl/ methylbutyrylcarnitine) and urine 2-methylbutyrylglycine(2-MBG) were markedly elevated; butyrylglycine and isobutyrylglycine were also detected in small amounts in the urine. SBCAD(short branched-chain acyl-CoA dehydrogenase) enzyme activity was undetectable in cultured skin fibroblasts and Western blot showed no detectable immuno-reactive protein. Molecular analysis of the 2-MBCD gene revealed a polymorphism in the leader peptide region(38G>A; Arg13Lys) and homozygous for a non-coding polymorphism 639T>C. This is the first such case in Korea. This disorder is known to be relatively common in one other oriental ethnic group, the Hmong. The baby has been fed on a maple syrup urine disease(MSUD)-similar diet program, and is still alive and is 26-months-old now. However, he developed significant neurologic complications including communicating hydrocephalus, cerebral palsy, and blindness. Presumably the prematurity and its complications may also attribute to his severe neurologic problems. However, the clinical course was particularly severe, a finding in contrast with the observation from several asymptomatic Hmong cases. The clinical course of 2-MBCDase deficiency could be very variable and careful monitoring and follow up should be considered.

OBJECTIVE: To compare perioperative outcome of robot-assisted radical hysterectomy with abdominal radical hysterectomy for early-stage cervical cancer and endometrial cancer and to evaluate the feasibility of robotic-assisted radical hysterectomy. METHODS: We reviewed medical record of 37 patients who had radical hysterectomy at Hallym university for cervical cancer stage Ia1 to IIa and endometrial cancer stage Ia to Ib. Abdominal radical hysterectomy was carried out in 27 (Abdominal group) patients and robot-assisted radical hysterectomy carried out in 10 patients (Robotic group). We compared patient's characteristics between two groups. Perioperative characteristics compared included cancer stage, operative time, number of nodes, estimated blood loss, length of hospital stay and complications. RESULTS: There were no differences in age, parity, history of medical disease, body mass index between two groups (p>0.05). Robotic operative times were significantly longer than for abdominal (480.0+/-117.8 vs. 286.9+/-65.6 min, p<0.0001). Blood loss (660.0+/-245.9 vs. 1,137.0+/-608.4 mL. p<0.0001) and length of hospital stay (7.2 versus 17.1 days, p<0.0001) were significantly lower for the robotic group. Lymph node yield in the robotic group was equivalent to that for the abdominal group (30.1+/-8.7 vs. 35.4+/-16.9, p=0.356). No major operative complications occurred with both groups. CONCLUSION: Robot-assisted radical hysterectomy appears safe and feasible in early-stage cervical and endometrial cancer.

OBJECTIVES: he purpose of this study was to examine psychosocial factors related to burnout of social welfare officers working in Jeonnam Province.METHODS: A total of 395 social welfare officers (male 99, female 296) working in 22 areas of Jeollanam-do province, were subjects of this study. We examined socio-demographic factors, using a self-reporting questionnaire. Subjects were asked to complete the Maslach Burnout Inventory-General Survey (MBI-GS), Center for Epidemiological Studies Depression Scale (CES-D), Perceived Stress Scale (PSS), and the Generalized Self-Efficacy Scale (GSS), to assess psychosocial factors affecting to burnout of social welfare officers.RESULTS: Among 395 subjects, 221 (55.9%) reported recent experiences of burnout. There was no significant difference in age between two groups, divided by burnout. Sex (p < 0.001), rank (p=0.003), working period (p=0.034), depression (p < 0.001) revealed differences between the burnout group and control group. Scores of PSS (p < 0.001) were higher, while the scores of GSS (p < 0.001) were lower in the burnout group, than control group. Multivariate logistic regression analysis revealed that female (OR 2.840, 95%CI 1.466–5.504, p=0.002), depressive high-risk group (OR 6.824, 95%CI 2.893–16.096, p < 0.001) PSS (OR 1.247, 95%CI 1.153–1.349, p < 0.001) and GSS (OR 0.950, 95%CI 0.930–0.971, p < 0.001), were significantly associated with burnout.CONCLUSION: We found that some factors, were associated with experienced burnout in social welfare officers. Depressive symptoms were the strongest associative factor, for burnout in public servants in charge of social welfare. Sex, stress and self-efficacy also correlated with burnout, and especially self-efficacy was a protecting factor.

PURPOSE: This study was performed to estimate the incidence of nosocomial sepsis and to identify the most relevant risk factors for nosocomial sepsis in high-risk very low birth weight (VLBW) infants. METHODS: A retrospective review of 341 VLBW infants, admitted to the Neonatal Intensive Care Unit of the Eulji University Hospital (Daejeon & Seoul) between January 2002 and June 2009, who survived more than 72 hours was performed. The incidence, causative organisms, risk factors and prognosis of nosocomial sepsis in VLBW infants were analyzed. RESULTS: The incidence of nosocomial sepsis was 16.1% and the onset date of nosocomial sepsis was 21.5+/-15.9 days (mean+/-SD) after delivery. Staphylococcus aureus (21.3%) was the most common organism in the patients with nosocomial sepsis in VLBW infants. The multiple logistic regression analysis showed that, gestational age [odds ratio (OR), 0.87; 95% CI, 0.83-0.91], umbilical artery catheter use for more than 5 days (OR, 2.2; 95% CI, 1.15-4.46), umbilical venous catheter use for more than 5 days (OR, 2.1; 95% CI, 1.11-4.16), peripheral arterial line use (OR, 2.1; 95% CI, 1.14-4.04) and intravenous intralipids (OR, 4.3; 95% CI, 1.13-14.32) were identified as risk factors. CONCLUSION: The limited usage of intravascular catheter related procedures and the short providence of intravenous nutrition may decrease the incidence of nosocomial sepsis in VLBW infants.

Rhizomelic chondrodysplasia punctata(RCDP) is a rare autosomal recessive disorder clinically characterized by symmetrical shortening of the proximal limbs, contractures of joints, a typical dysmorphic face, cataracts, and itchyosis. Patients with RCDP can be subdivided into three subgroups based on biochemical analysis and complementation studies. RCDP type I results from mutations in the PEX7 gene encoding the peroxisomal targeting signal type II(PST2) receptors and presents with both a defect in plasmalogen biosynthesis and phytanic acid oxidation. RCDP type II is deficient in the activity of dihydroxyacetonephosphate acyltransferase(DHAP-AT). RCDP type III is deficient in alkyl-dihydroxyacetonephosphate synthase(alkyl-DHAP). We report a case of RCDP type I which was confirmed with biochemical study, fibroblast culture, and gene study.

For many years, the histogenesis of the granular cell tumor was controversial and this resulted in the tumor being given more than 20 synonyms. Abrikossoff, reporting on the fiist granular cell tomor, favored a muscle origin, but other authora have postulated a fibroblastic or a histiocytic origin. Recently, the concept of Schwann cell origin, supported by electron microscopic studies and immunohistochemistry of S-100 protein, has gained wider recognition. Approximately 90 cases of esophageal granular cell tumor have been reported in the literature, representing about 2% incidence of all reported granular cell tumor, In Korea, only four cases of granular cell tumors were reported in the literatures including the cases occuring in the cecum, colon, and anus until now. Recently we experienced 46-years old women with granular cell tumor of the esophagus, which might be the second case in Korean literature.

Total 8,341 pregnant women who visited Obstetric Clinic Cheil General Hospital from Jaunary 1991 to July 1992 were screened for HBsAg. Sixty five women with positive HBsAg who delivered healthy babies during that period and their infants are included in the study. HBsAg, Anti-HBs, Anti-HBc, HBeAg and Anti-HBe were tested by radioimmunoassay and hepatitis B virus DNA were studied by polymerase chain reaction technique in both mothers' and babies serum. The results were as follow: 1) Among 8,341 pregnant women who were screened for HBsAg 374 were asymptomatic carriers(4.5%). 2) The newborn babies born to 65 mothers who were positive HBsAg showed HBsAg in 4.6%, HBeAg 75.0%, anti-HBc 98.4% and hepatitis B virus DNA in 26.2%. 3) It showed discordance of HBeAg/anti-HBe, with hepatitis B virus DNA in newborn infants. 4) Follow up study at 8~20 months showed HBeAg and hepatitis B virus DNA in 2 infants out of 20.
