Leiomyoma is a neoplasm of smooth muscle relatively common in the stomach, but very rare in the duodenal location. Recurrent bouts of severe melana remain the most frequent presenting symptom for leiomyoma. A 69-year-old man presented to us with a 4-day history of melena. Endoscopy revealed norinal mucosa covered ovoid elevated lesion with central linear depression and ulcer at the second portion of duodenum. Endoscopic biopsy showed chronic inflammation only. Duodenal mass was excised through a duodenotomy. Pathological diagnosis was leiomycena.

PURPOSE: The purpose of this study is to evaluate the accuracy of differentiation between benign and malignant clustered microcalcifications without mass on mammogram. MATERIAL AND METHODS: Fourty six mammogramsof 44 patients showing clustered microcalcifications without mass were interpreted blindly by five independent observers majoring in breast imaging from different institutions. Twenty two were malignant (10 infiltratingductal carcinomas, 12 intraductal carcinomas) and 24 were benign (all fibrocystic disease). The observers judgebenignancy or malignancy of microcalcifications. The authors assess the accuracy of differential diagnosis of clustered microcalcifications. RESULT: Of 24 cases proved benign microcalcifications, five radiologists correctly interpreted 20 on average as benign and of malignant 22 cases, 16 on average were correctly interpreted asmalignant. The diagnostic accuracy of malignant microcalcifications was 71.8% on average(63.6%-81.8%) and the diagnostic accuracy for benign microcalcifications was 83% on average(71% - 92%). It was 9 among total 46 cases that were misinterpreted by more than three radiologists. Among these 9 cases, malignant microcalcifications thathad been misinterpreted as benign were seven, benign microcalcifications misinterpreted as malignant were two. CONCLUSION: The diagnostic accuracy of clustered malignant microcalcifications(71.8%) without mass on mammogramwas lower than that of benign microcalcifications(83.3%). So, in case of suspected malignant microcalcification onmammogram, it is preferable that along with magnification view, histopathologic confirmation by core biopsy mustbe obtained.

Background:
To determine the effects of Jerusalem Artichoke extract (JAE) and inulin on blood glucose levels and insulin secretion in streptozotocin (STZ)-induced diabetic mice.
Methods:
Thirty four mice were divided into a normal control group and three experimental groups: diabetic control, JAE, and inulin. STZ (50 mg/kg) was injected intraperitoneally to induce diabetes in the three experimental groups. The JAE and inulin groups were fed 10 g/kg JAE or fed 1 g/kg inulin, respectively, for 6 weeks. Fasting glucose was checked weekly. After 6 weeks, the oral glucose tolerance test (OGTT) was performed, and the insulin level was checked.
Results:
Four mice from the JAE group (n = 9) died and autopsies revealed inflammation and ulceration of skin lesions on the chest areas. Fasting glucose levels were not decreased in the inulin or JAE group relative to diabetic control group. In the OGTT at 60 minutes and 120 minutes, the serum glucose levels were significantly higher in the inulin group (572.6 ± 52.0 mg/dL and 555.8 ± 72.9 mg/dL, respectively) than in diabetic control group (484.3 ± 81.6 mg/dL and 467.3 ± 111.1 mg/dL, respectively). Insulin levels were not increased in the inulin group relative to the diabetic control group.
Conclusion
These results indicate that JAE and inulin might not be useful therapeutic strategies for diabetes mellitus and indiscreet intake of Jerusalem Artichoke could exacerbate to diabetes.

BACKGROUND/AIMS: To evaluate the diagnostic value of contrast (SonoVue(R)) enhancement ultrasonography (CEUS) and to compare this method with computed tomography (CT) and magnetic resonance imaging (MRI) in evaluating liver masses. METHODS: CEUS (n=50), CT (n=47), and MRI (n=43) were performed on 50 liver masses in 48 patients for baseline mass characterization. The most likely impression for each modality and the final diagnosis, based on the combined biopsy results (n=14), angiography findings (n=36), and clinical course, were determined. The diagnostic value of CEUS was compared to those of CT and MRI. RESULTS: The final diagnosis of the masses was hepatocellular carcinoma (n=43), hemangioma (n=3), benign adenoma (n=2), eosinophilic abscess (n=1), and liver metastasis (n=1). The overall diagnostic agreement with the final diagnosis was substantial for CEUS, CT, and MRI, with kappa values of 0.621, 0.763, and 0.784, respectively. The sensitivity, specificity, and accuracy were 83.3%, 87.5%, and 84.0%, respectively, for CEUS; 95.0%, 87.5%, and 93.8%, respectively, for CT; and 94.6%, 83.3%, and 93.0%, respectively for MRI. After excluding the lesions with poor acoustic sonographic windows, the sensitivity, specificity, and accuracy for CEUS were 94.6%, 87.5%, and 93.3%, respectively, with a kappa value of 0.765. CONCLUSIONS: If an appropriate acoustic window is available, CEUS is comparable to CT and MRI for the diagnosis of liver masses.
