A biloma is an extrahepatic or intrahepatic bile collection caused by traumatic, iatrogenic, or spontaneous rupture of the biliary tree. Prior reports have documented an association of a biloma with abdominal trauma and surgery, but spontaneous bile leakage associated with other primary causes has rarely been reported. A 72-year-old man was admitted to our hospital with the complaint of epigastric pain and yellowish discoloration of the sclera. Ultrasonography and computed tomography revealed a large fluid collection in the abdominal cavity. Endoscopic retrograde cholangiography demonstrated leakage of contrast medium from a distended segmental biliary branch in the left lobe of the liver. A perihepatic biloma was confirmed by sonographically guided percutaneous aspiration, and the patient underwent a left lateral segmentectomy of the liver, a cholecystectomy and T-tube choledochostomy. Histological examination showed left lateral bile duct hyperplasia, with abscess formation and chronic cholecystitis. Herein, a case of a biloma associated with choledocholithiasis is reported, with a review of the literatures.

Epstein-Barr virus (EBV)-associated disease is known to be one of the major complication after transplantation. Early identification and diagnosis is crucial. The objectives of this study are to evaluate the incidence and to analyze the risk factors of EBV-associated disease. Twenty-five children with liver transplantation from Oct. 1994 to Oct. 1997 had been surveyed. Laboratory data of EBV infection such as anti-viral capsid antigen (VCA) IgM and IgG, EBV PCR, EBV encoded small RNA (EBER) in situ hybridization had been obtained at pre op, and post op 1, 2, 3, 4, 12, 24 weeks, then annually or when EBV infection was suspected. We classified these cases as asymptomatic infection, EBV syndrome, posttransplant lymphoproliferative disease (PTLD). And we analyzed the incidence of EBV infection according to age, type of immunosuppression, and CMV disease. Incidence of EBV infection in this study was 48% (12 out of 25), among them, 5 children were symptomatic and PTLD developed in 2 children. The significant risk factors were age at transplantation and CMV infection. One of PTLD cases resulting from EBV infection showed fatal outcome, the other was improved. We suggested that physicians especially in the care of the children after the liver transplantation should recognize the risk factors of the development of the EBV infection to avoid the progression into the potentially fatal PTLD.

BACKGROUND: Lung abscess is necrosis of the pulmonary parenchyma caused by microbial infection. At present, clinical outcomes after treatment are good. However, the pulmonary parenchymal changes on the chest computed tomography (CT) after treatment are not well known. We studied the changes of pulmonary parenchyma on plane chest radiography and chest CT in patients with lung abscess following the administration of antibiotics. METHODS: We retrospectively reviewed 39 patients who had lung abscess with or without combined pneumonia from January 2006 to July 2010. We studied the therapeutic response in plane chest radiography of them at 1, 2, or more than 3 months following treatment. If any chest CT of them during the study period, we reviewed. RESULTS: Mean age of the patients was about 61.3+/-11.2. Mean duration of antibiotics administration was about 36.7+/-26.8 days. After 3 months of following plane chest radiography, 10 patients (36%) showed without residual sequelae among 28 patients. Findings from other patients showed decrease in densities (11 patients, 39%), fibrostreaky sequelae (4 patients, 14%) and bullae (3 patients, 10%). After more than 2 months, chest CT was checked only in 7 patients. Among the 7 patients, 4 patients showed no residual lesion, 3 patients showed decreased densities on plane chest radiography. Chest CT revealed fibrostreaky densities in 2 patients, ground glass opacities in 3 patients, bullous formation in 1 patient, and cystic bronchiectasis in 1 patient. CONCLUSION: After more than 2 months following treatment for lung abscess even though there were no lesions on plane chest radiography, chest CT showed fibrostreaky or ground glass opacity.

PURPOSE: The purpose of this study was to examine nursing organizational culture and resilience and their effects on quality of nursing service. METHODS: A cross-sectional study was conducted. A convenience sampling method was used to collect data from 199 participants who worked in a tertiary hospital in G city. Demographic and work related variables, quality of nursing service, resilience, and nursing organizational culture were measured using validated self-report questionnaires. RESULTS: All of the participants were women and the majority were staff nurses and single. A statistically significant difference in quality of nursing service was found for age, marital status, educational level, clinical career, position and perceived health status. Age, educational level, clinical career, position, resilience, innovation-oriented culture, relation-oriented culture, and hierarchy-oriented culture were significant predictors of quality of nursing service, explaining 47% of total variance. Among the predictors, resilience was the strongest predictor, followed by innovation-oriented culture, and hierarchy-oriented culture. CONCLUSION: Findings indicate that quality of nursing service can be improved by raising individual nurse's resilience and advancing nursing organizational culture. Considering the identified factors, researchers and administrators need to develop and provide clinical nurses with a variety of programs to improve the quality of their nursing service.

BACKGROUND/AIMS: Both the farnesoid X receptor (FXR) and peroxisome proliferator-activated receptor (PPAR) play important roles in lipid metabolism and atherosclerosis. We investigated the interaction between FXR and PPARgamma. METHODS: Apolipoprotein E knockout (ApoE-/-) mice and FXR knockout (FXR-/-) mice were crossed to generate ApoE-/-FXR-/- mice. The mice were divided into ApoE-/-, ApoE-/-FXR-/-, and ApoE-/-FXR-/- + pioglitazone groups. All mice were fed a high-fat, high-cholesterol diet for 12 weeks. The ApoE-/-FXR-/- + pioglitazone group was also treated with pioglitazone, 20 mg/kg body weight. Body weight, blood glucose level, lipid profile, and liver enzyme levels were measured. To evaluate atherosclerotic lesions, the aorta was stained with Oil red O. RESULTS: There were no differences in body weight or blood glucose level among the three groups. The serum lipid concentration and liver enzyme levels increased in the ApoE-/-FXR-/- group compared with the ApoE-/- group (p < 0.01). The ApoE-/-FXR-/- + pioglitazone group had lower high-density lipoprotein (HDL) (55 +/- 4 vs. 28 +/- 2 mg/dL, p < 0.01) and low-density lipoprotein (LDL) (797 +/- 26 vs. 682 +/- 47 mg/dL, p = 0.04) cholesterol than the ApoE-/-FXR-/- group. The respective percentages of aortic atherosclerotic plaques in the ApoE-/-, ApoE-/-FXR-/-, and ApoE-/-FXR-/- + pioglitazone groups were 2.7 +/- 0.2%, 7.7 +/- 1.2%, and 18.6 +/- 1.0%. In ApoE-/-FXR-/- mice, the administration of pioglitazone significantly increased the number of atherosclerotic lesions (p = 0.02). CONCLUSIONS: Pioglitazone increased the number of atherosclerotic plaques in ApoE-/-FXR-/- mice. This suggests that when FXR is inhibited, the activation of PPARgamma can aggravate atherosclerosis.
