PURPOSE: To compare T2-weighted MR cholangiography (T2-MRC) and contrast-enhanced T1-weighted MRC (enhanced T1-MRC) in the assessment of biliary anatomy in donor candidates for living related liver transplantation (LRLT). MATERIALS AND METHODS: Thirty-three potential donors underwent MR examination for preoperative evaluation. Using the single-shot half-Fourier RARE sequence, T2-weighted single-section and coronal images were obtained, and enhanced T1-MRC was performed, using 3D GRE sequences after the administration of mangafodifir trisodium. To assess the hilar ductal branching pattern and determine diagnostic confidence, two reviewers first evaluated the unpaired T2-MRC and enhanced T1-MRC images, and then paired T2-MRC and enhanced T1-MRC images together. In particular, in 12 cases in which direct cholangiographys were performed, the feasibility of single duct-to-duct anastomosis was assessed using the unpaired and the paired sets sequentially. RESULTS: The reviewers' confidence tended to be higher for enhanced T1-MRC than T2-MRC, but the difference was not statistically significant. For both reviewers, confidence was significantly higher for the paired set than for T2- or enhanced T1-MRC alone (p < .001). The types of biliary anatomy determined in the paired set matched the consensus reading in 33 (100%) and 30 cases(91%) assessed by reviewer 1 and 2, respectively. The separate interpretation of T2- and enhanced T1-MRC findings matched the consensus interpretation in 30 (91%) and 28 cases (85%), respectively, assessed by reviewer 1, and 26 (79%) and 28 cases (85%), respectively, assessed by reviewer 2. The possibility of single anastomosis was accurately predicted in 91.6% of cases in T2-MRC, and 100% at enhanced T1-MRC and the combined set. CONCLUSION: In the evaluation of the biliary anatomy of potential donors for LRLT, the combined use of T2-MRC and enhanced T1-MRC may improve diagnostic confidence and decrease the occurrence of a non diagnostic or equivocal interpretation at T2-MRC alone.

Mechanical complications of acute myocardial infarction which may lead to heart failure or shock include ruptute of left ventricular free wall, ventricular septum and papillary muscle. The clinical characteristics of these lesions vary conservative management alone has high mortality rate, for which reason surgical repair of these defects are essential. Structural defects including rupture of the left ventricular free wall, ventricular septum, and papillary muscle, accout for 5% to 20% of all deaths from acute myocardial infarction. Among these, ventricular septal defects occur in approximately 1% of all myocardial infarction, and account for up to 2% of deaths subsequent to myocardial infarction. Rupture of the ventricular septum following acute myocardial infarction(AMI) is associated with high mortality rate, as 54% of the patients succumb within two weeks, 87% within two months and 92.5% during the first year. We experienced two cases of postinfarct ventricular septal defects(VSD) which had been repaired within 1 week after AMI due to progressive deterioration of patients` conditions, and were to be reoperated because of repeated septal ruptures in postoperation period and development of cardiogenic shock.

BACKGROUND: Emergence agitation (EA) in children after sevoflurane anesthesia is common. The purpose of this study was to compare the incidences of EA between ketamine and thiopental sodium induction in children underwent sevoflurane anesthesia. We also evaluated if a small dose of fentanyl could reduce the incidence of EA. METHODS: The patients who were scheduled for strabismus or entropion surgery were divided into 4 groups. The patients in Groups 1 and 2 were induced anesthesia with ketamine 1.5 mg/kg; those in Groups 3 and 4 were induced with thiopental sodium 5 mg/kg. The patients in Groups 1 and 3 received an injection of fentanyl 1.5 microgram/kg, whereas the patients in Groups 2 and 4 received IV saline of the same volume. Anesthesia was maintained with sevoflurane. The recovery characteristics and EA in recovery room were assessed. RESULTS: The incidence of EA was significantly higher in Groups 2 and 4 and there was no difference between Groups 2 and 4. Group 2 had almost an eleven-fold higher risk of developing EA than did Group 1, and the incidence of EA in Group 4 was sixty-nine-fold higher than that of Group 1. The risk factor for EA was only the kind of medication. Preoperative anxiety had no significant correlation with EA. CONCLUSIONS: The incidence of EA after sevoflurane anesthesia is similar between ketamine and thiopental sodium anesthetic induction in children undergoing pediatric ophthalmic surgery. Also, the addition of a small dose of fentanyl after anesthetic induction decreases the incidence of EA.

BACKGROUND: The incidence of postoperative nausea and vomiting after cardiac surgery is 30-40%.The role of a nasogastric tube for reducing the PONV is still controversial. METHODS: 92 patients who were undergoing cardiac surgery with cardiopulmonary bypass were randomized to a receive nasogastric tube after induction of anesthesia (Group 2) or they were placed in the control group (no nasogastric tube) (Group 1).The patients with a history of gastric/esophageal surgery, esophageal varix, esophageal stricture and/or a history of antiemetic treatment were excluded.Routine fast-track cardiac anesthesia and postoperative care were employed for all the patients.The incidence of PONV was recorded hourly for the first four hours after extubation and then every 4 h afterwards for 24 h.The usage of antiemetics and pain medication was also recorded.The data was analyzed with t-tests and chi-square tests for the continuous variables and the categorical data, respectively.P values < 0.05 were considered statistically significant. RESULTS: The groups were similar with respect to the demographic data, the surgical characteristics and the opioid usage.There was no significant difference in the incidence of PONV and the antiemetic usage between the two groups. CONCLUSIONS: This study showed that placement of a nasogastric tube did not have an impact on the incidence of PONV or the requirements for antiemetics after cardiac surgery.The results of this study do not support the use of a nasogastric tube to reduce PONV after cardiac surgery.

PURPOSE: To describe the clinical and imaging findings of hepatocellular carcinoma with neuroendocrine differentiation, which is an extremely rare variant of hepatocellular carcinoma. MATERIALS AND METHODS: We collected five patients who had histopathologically proven hepatocellular carcinoma with neuroendocrine differentiation, and described morphologic feature, enhancement pattern of tumors, extrahepatic manifestation and clinical findings. RESULTS: At CT, the tumor size ranged from 8 to 17 cm (mean : 12 cm) in maximum diameter. The tumor margin was well-defined and smooth in four patients and all tumors were heterogeneously hypoattenuating. Four tumor showed rim enhancement on arterial and portal phases. Local invasion to the portal vein, intrahepatic duct and gallbladder were seen. Extrahepatic manifestations included hepatic metastases, lymph node metastasis. At ultrasonography, the tumor showed heterogeneously hyperechoic in all patients and hypoechoic rim was found in four patients. Of four patients who were followed up, one survived for 16 months after initial diagnosis, while the other three died within 3 months after initial diagnosis. CONCLUSION: As described above, clinical and imaging findings of hepatocellular carcinoma with neuroendocrine differentiation were not specific. However, this rare variant of hepatocellular carcinoma could be considered when hepatic tumor is found in an advanced stage and shows persistent rim enhancement at CT.

As prediction of rapidly aging society, bone health is considered increasingly important and received more attention than ever. Bone health is regulated by balancing between bone resorptive osteoclasts and bone formative osteoblasts. Disruption of balance between bone-resorbing osteoclasts and bone-forming osteoblasts results in bone disease. Natural products have recently received much attention as an alternative tool for the development of novel therapeutic strategy. Baicalein is reported it has anti-cancer, anti-inflammatory and antioxidant effects. Baicalein also has been known that it has both promotive effect on MC3T3-E1 cell line and inhibitory effect on RAW 264.7 cell line. However, the inhibitory mechanism of baicalein using bone marrow derived macrophages (BMMs) on osteoclast differentiation remains not clear. In this study, the suppressive mechanism by baicalein on osteoblast differentiation was evaluated. Bicalein inhibited receptor activator of nuclear factor-kappaB ligand (RANKL)-induced osteoclast differentiation in BMMs in a dose dependent manner without any toxicity. Baicalein suppressed phosphorylation of protein kinaseB (Akt), c-Jun N-terminal kinases (JNK) and phosphoinositide-specific phospholipaseCgamma2 (PLCgamma2). Furthermore, Baicalein suppressed the induction of RANKL-induced c-Fos and Nuclear factor of activated T cell c1 (NFATc1), essential genes on osteoclastogenesis. In BMMs, Bicalein inhibited the mRNA expression of tartrate-resistant acid phosphatase (TRAP), osteoclast-associated receptor (OSCAR), cathepsinK, dendritic cell-specific transmembrane protein (DC-STAMP). Moreover, baicalein promoted differentiation of osteoblast on bone marrow stromal cells (BMSCs). Taken together, these results suggest that baicalein has a potential for treating bone lytic diseases, such as osteoporosis, periodontitis, and rheumatoid arthritis.

BACKGROUND/AIMS: Transarterial chemoembolization (TACE) is the standard locoregional treatment in patients with unresectable hepatocellular carcinoma (HCC). Angiogenesis and inflammation play important roles in tumor growth in HCC. In this study, we evaluated the associations between the levels of growth factors and inflammatory markers and clinical prognosis in patients with unresectable HCC treated with TACE. METHODS: The clinical outcomes of 58 HCC patients treated with TACE at the Catholic Medical Centers from January, 2012 to February 2015 were evaluated. Baseline levels of the growth factors vascular endothelial growth factor, fibroblast growth factor, platelet-derived growth factor, and hepatocyte growth factor and the inflammatory cytokines interleukin (IL)-17 and high sensitivity C-reactive protein (hs-CRP) were compared with the treatment outcomes. The primary endpoint was time to progression (TTP); the secondary endpoint was overall survival (OS). RESULTS: During the 20.8 months of follow-up, TTP was significantly delayed in patients with low levels of hs-CRP (≤0.15) and IL-17 (≤0.94) and a maximal tumor diameter ≤5 cm (P=0.010, P=0.015, and 0.048, respectively). Patients with HCC with low hs-CRP and IL-17 levels had a longer survival than that of those with high hs-CRP levels and IL-17 (35.1 vs. 22.5 months, P=0.000; 41 vs. 21.8 months, P=0.000, respectively). However, any baseline growth factors were not significantly correlated with TTP and OS. CONCLUSIONS: Elevated IL-17 and hs-CRP may be predictive of a poor outcome in patients with HCC treated with TACE. A better understanding of this relationship will require further investigation of the immune mechanisms underlying tumor progression.
