METHODS: One hundred and forty-one patients who applied CE for OGIB between 2009 and 2012 were retrospectively analyzed, and this cohort was then questioned prospectively. Demographic data of the patients were determined via the presence of comorbid diseases, use of non-steroidal anti-inflammatory drugs anticoagulant-antiaggregant agents, previous diagnostic tests for bleeding episodes, CE findings, laboratory tests and outcomes.RESULTS: CE was performed on 141 patients becauseof OGIB. The capsule was retained in the upper gastrointestinal(GI) system in two of the patients, thus video monitoring was not achieved. There were 139 patients [62% male, median age: 72 years(range: 13-93 years) and a median follow-up duration: 32 mo(range: 6-82 mo)]. The overall diagnostic yield of CE was 84.9%. Rebleeding was determined in 40.3%(56/139) of the patients. The rebleeding rates of patients with positive and negative capsule results at the end of the follow-up were 46.6%(55/118) and 4.8%(1/21), respectively. In the multivariate analysis, usage of NSAIDs, anticoagulant-antiaggregant therapies(OR = 5.8; 95%CI: 1.86-18.27) and vascular ectasia(OR = 6.02; 95%CI: 2.568-14.146) in CE were detected as independent predictors of rebleeding. In the univariate analysis, advanced age, comorbidity, and overt bleeding were detected as predictors of rebleeding.CONCLUSION: CE is a reliable method in the diagnosis of obscure GI bleeding. Negative CE correlated with a significantly lower rebleeding risk in the long-term follow-up period.展开更多

On clinical grounds, a diagnosis of myocarditis was established. He had a peak troponin I level as high as 40.4 ng/dl but interestingly with no abnormal wall motion and normal ejection fraction in echocardiography. Coronary artery disease was excluded with normal coronary angiography. Diagnosis of myocarditis was confirmed with cardiac MRI. After one month, patient had no complaint and ejection fraction were still normal. Our case emphasizes that the troponin levels predict neither the early nor the late outcome of the left ventricular functions in myocarditis, therefore serum troponin I may not be helpful in determining the prognosis of patients with myocarditis.展开更多

Extramedullary plasmacytoma, in particular pancreatic plasmacytoma, is a rare manifestation of multiple myeloma. Although computerized tomography is useful for the diagnosis of extramedullary plasmacytoma, there are no specific radiologic markers that distinguish it from adenocarcinoma. Histological confirmation by biopsy is necessary for accurate diagnosis and management of the tumor. Endosonography is the most sensitive method for the diagnosis of pancreatic tumors, and the use of fine needle aspiration by endosonography is associated with a lower risk for malignant seeding and complications. Here, we report a case of pancreatic plasmacytoma in newly identified multiple myeloma as diagnosed by endosonography. Endosonography is a reliable and rapid method for the diagnosis of extramedullary plasmacytoma. Therefore, endosonographic fine needle aspiration should be the first choice for histological evaluation when pancreatic plasmacytoma is suspected. Ideally, the pathology would be performed at the same site as endosonographic biopsy.展开更多

Actinomyces israelii is usually responsible for the infections and causes chronic suppurative and granulomatous infections. The most common disease form is cervicofascial infection. Liver is involved in 5% of all actinomycosis infections. Liver involvement secondary to any primary infection site in the abdomen frequently occurs. In 15% of abdominal infections the liver is also involved. However, in very rare cases, a primary focus cannot be found, and these cases are called primary or isolated hepatic actinomycosis (IHA). IHA which is frequently seen as a solitary abscess can be confused with a malignancy both clinically and radiologically.展开更多

The diagnosis was established by histopathological and/or radiological criteria. We retrospectively reviewed clinical and laboratory data, etiology of primary liver disease, imaging characteristics and treatments. ChildPugh and Barcelona Clinic Liver Cancer stage was determined at initial diagnosis. Kaplan-Meier survival analysis was done to find out treatment effect on survival. Risk factors for vascular invasion and overall survival were investigated by multivariate Cox regression analyses. RESULTS Five hundred and forty-five patients with hepatocellular carcinoma were included in the study. Viral hepatitis was prevalent and 68 patients either had normal liver or were non-cirrhotic. Overall median survival was 16(13-19) mo. Presence of extrahepatic metastasis was associated with larger tumor size(OR = 3.19, 95%CI: 1.14-10.6). Independent predictor variables of vascular invasion were AFP(OR = 2.95, 95%CI: 1.38-6.31), total tumor diameter(OR = 3.14, 95%CI: 1.01-9.77), and hepatitis B infection( OR = 5.37, 95 % CI : 1.23-23.39). Liver functional reserve, tumor size/extension, AFP level and primary treatment modality were independent predictors of overall survival. Transarterial chemoembolization(HR = 0.38, 95%CI: 0.28-0.51) and radioembolization(HR = 0.36, 95%CI: 0.18-0.74) provided a comparable survival benefit in the real life setting. Surgical treatments as resection and transplantation were found to be associated with the best survival compared with loco-regional treatments(log-rank, P < 0.001).CONCLUSION Baseline liver function, oncologic features including AFP level and primary treatment modality determines overall survival in patients with hepatocellular carcinoma.展开更多
