Primary retroperitoneal mucinous tumor is very rare. In the worldwide literature, only 14 cases have been reported. Herein, we report two cases of retroperitoneal mucinous tumor found at laparotomy. The patients were females, aged 24 and 21 years, respectively. They had bilateral normal ovaries. Histologically, one was mucinous cystadenoma and the other showed borderline histology. The connective tissue wall resembling ovarian stroma was noted in one case. The pathogenesis was discussed.

Focal nodular hyperplasia (FNH) is characterized by the presence a central scar with radiating fibrous septa. Our case had a capsular retraction, which was the result of an extension of the central scar to the surface. In addition, a hypointense scar on the T2-weighted image and a minimal enhancing central scar on the enhanced T1-weighted image, which was due to dense, sclerotic collagenous tissue, were observed. We report the first case of FNH with a capsular retraction.

PURPOSE: Liver function test abnormalities have been reported frequently in patients receiving total parenteral nutrition (TPN). In adults, it is known that liver complications decrease with the use of cyclic parenteral nutrition (CPN), especially if the shift to cycling was not too late. However, there are few studies about the effects of cycling on liver injury in children beyond the neonatal period. The aim of this study is to evaluate the effect of the early use of CPN on total parenteral nutrition induced hepatic dysfunction. METHODS: Twelve sets of CPN in 11 children (2 months to 17 years) were included in this study. Data on underlying diseases, age, length of time on TPN, macronutrient intake, complications, and biochemical parameters were collected from clinical records. All children had received CPN in the early period of persistent transaminase elevation or cholestasis complicated by previous continuous PN. The duration of infusion off-time in CPN was 2 hours in patients less than 3 months of age and 4 hours in the older children. RESULTS: All 12 cases showed elevated aminotransferase and 5 of them also showed cholestasis. Serum total bilirubin concentration was normalized in all 5 cases with median periods of 8 days (p<0.05) after initiation of CPN. ALT either decreased significantly or was normalized in all cases with median periods of 30 days (p<0.05) on CPN. The CPN was well tolerated without significant complication except for one case of hyperglycemia. CONCLUSION: The early use of cyclic parenteral nutrition had a beneficial effect in improving hepatic dysfunction complicated by TPN in children.

OBJECTIVES: The purpose of this study was to evaluate the psychometric properties of the Korean version of the Richmond Compulsive Buying Scale (RCB-K). METHODS: Participants (n=598) included patients recruited through an online panel survey. For the semantic adaptation step, the scale was translated into Korean and then back-translated to English by one psychologist, one public health professional, one psychiatrist who could speak both Korean and English, and one professional translator, without communication between those involved. A confirmatory factor analysis was performed to test whether the factor structure of the RCB-K was consistent with the English version. Convergent validity was assessed by correlating the RCB-K scores with those of other scales (i.e., O'Guinn & Faber's Compulsive Buying Scale, Problem Gambling Inventory). RESULTS: The factor structure of the RCB-K was consistent with the two-factor structure established for the original RCB. Cronbach's α was high (0.906), indicating that the reliabilities of the items in each subscale were satisfactory. The RCB-K score was significantly correlated with those for the O'Guinn & Faber's Compulsive Buying Scale (r=0.7) and the Problem Gambling Inventory (r=0.422). CONCLUSION: The results of the present study indicate that the RCB-K is an effective and valid scale for evaluating the severity of compulsive buying. The findings suggest that the RCB-K is a promising assessment tool for use in the treatment and study of online compulsive buying behavior.

PURPOSE: Alagille syndrome is an autosomal dominant disorder with developmental abnormalities affecting the liver, heart, eyes, vertebrae, and craniofacial region. The Jagged1(JAG1) gene, which encodes a ligand of Notch, has been found mutated in Alagille syndrome. The aim of the study was to investigate the mutation analysis of JAG1 gene in Korean patients with Alagille syndrome. METHODS: Genomic DNA was extracted from peripheral leukocytes of 6 patients. The 26 exons of JAG1 gene were amplified and PCR products were directly sequenced. RESULTS: Two novel frameshift mutations were found. 118delC in exon 2 was found in a patient who developed hepatocellular carcinoma at 4 years of age. 999-1000delTG was identified in exon 7. CONCLUSION: Mutations identified in this study are expected to give rise to truncated proteins.

PURPOSE: The objective of this study is to confirm the effects of risk factors on Adjacent Segment Disease (ASD). MATERIALS AND METHODS: The subjects of this study were 793 patients who had degenerative lumbar spine disease and were followed-up for an average period of 7.2 years from January of 1999 to September of 2010 after undergoing spinal fusion. To confirm the risk factors, a study on patient factors, surgical factors and radiologic factors was performed. RESULTS: Of 793 patients, 69 patients (group A, 8.7%) underwent a secondary surgical treatment due to ASD. Age of patient, sex, bone mineral density, history of smoking and occupation were not statistically significant. Preoperative body mass index (BMI) (> or =25 kg/m2) and postoperative increase of BMI were the patient's factor in ASD (p=0.02, p<0.001). Regarding surgical factors, multilevel fusion (more than 3 levels) was higher risk in prevalence of ASD than short level fusion (p=0.01). Degeneration of intervertebral disc (p=0.01) and facet joints (p=0.02), and segmental instability (p=0.001) were also associated with the prevalence of ASD in radiologic factors. CONCLUSION: To prevent the occurrence of ASD after lumbosacral fusion, selection of the proper level of fusion preoperatively and modifying the life style with body weight control and reduction of hypermobility after fusion surgery are essential.

PURPOSE: The purpose of this study was to identify the predictors of acculturative stress among Chinese students in Korea. METHODS: Between October and December 2009, two hundred one Chinese students from three universities located in Cungnam province, were included in the current study using a questionnaire survey. Data analysis was done using SPSS/WIN 17.0 program. RESULTS: The average score of acculturative stress was 38.50+/-6.97. There were significant differences in acculturative stress according to educational level, economic status, type of residence, speaking skill in Korean, listening skill in Korean, grade point average, satisfaction for studying abroad, and perceived health status. The acculturative stress was significantly correlated with depression, resilience and social support. The strongest predictor of acculturative stress among Chinese students was depression. CONCLUSIONS: The findings suggest that developing programs to improve psychological health may provide a buffer against acculturative stress experienced by migrating Chinese students. Furthermore, more studies are needed to explore variables that influence on the international students' acculturation in Korea.

PURPOSE: This study was to identify the health status and reported resilience according to acculturation type among Chinese students in Korea. METHODS: The subjects were 386 Chinese students studying in three universities in Chungnam province. The data were collected by standardized questionnaires and SPSS/WIN 15.0 program was used to analyze the data with descriptive statistics, Chi-square, t-test, and ANOVA. RESULTS: Subjects reported the following Acculturation type: integration (26.7%), assimilation (28.5%), separation (32.4%), and marginalization (12.4%). The reported resilience was significantly different according to economic status. The health status was significantly different according to religion and economic status. Acculturation type was significantly different according to age, educational level, length of stay, type of residency and economic status working style. The health status and resilience were significantly different according to acculturation type. CONCLUSION: The findings suggest that integration of acculturation type is most useful to health status and resilience among Chinese students in Korea. Future studies need to examine acculturation type as coping strategy for foreign students' adaptation.
