Abstract | A 45-year-old female who presented with loss of consciousness and a cold sweat was found to have a pancreatic tumor and multiple liver metastases. Laboratory studies showed marked hypoglycemia and inappropriately elevated serum insulin, C-peptide, and serum tumor markers. Fine needle aspiration revealed Grade 3 small-cell type primary pancreatic neuroendocrine carcinoma. Consequently, the diagnosis of malignant insulinoma was made. Transarterial embolization (TAE) for hepatic metastases resulted in the reduction of tumor volume and prompt resolution of hypoglycemic attacks, whereas diazoxide and systemic chemotherapy had been ineffective for controlling blood glucose levels, and octreotide was unavailable due to the allergic effect. This case report highlights the potential usefulness of TAE for malignant insulinomas in the management of hypoglycemia. |

Abstract | A 67-year-old Japanese man underwent enterotomy because of enterolith ileus. Component analysis by infrared spectroscopy revealed that the enterolith was composed of a high concentration of deoxycholic acid. We further analyzed and compared the ultrastructure of the enterolith and a commercially available powdered form of deoxycholic acid by means of scanning electron microscopy and energy dispersive X-ray spectroscopy. Energy dispersive X-ray spectroscopy analysis revealed that the ratios of carbon and oxygen in the enterolith were equal to those in the deoxycholic acid powder. Scanning electron microscopy analysis showed rectangular prism-shaped particles on the surface of the enterolith. This structure was similar to that of the deoxycholic acid powder. The surgically removed enterolith had a twisted and coiled appearance. Possible mechanisms underlying the formation of this unique form are discussed. |

Abstract | The sensitivity and specificity of magnified endoscopic features for differentiating follicular lymphoma from other diseases with duodenal whitish lesions have never been investigated. Here we compared the magnified endoscopic features of duodenal follicular lymphoma with those of other whitish lesions. We retrospectively reviewed the cases of patients with follicular lymphoma (n=9), lymphangiectasia (n=7), adenoma (n=10), duodenitis (n=4), erosion (n=1), lymphangioma (n=1), and hyperplastic polyp (n=1). The magnified features of the nine follicular lymphomas included enlarged villi (n=8), dilated microvessels (n=5), and opaque white spots of various sizes (n=9). The lymphangiectasias showed enlarged villi, dilated microvessels, and white spots, but the sizes of the white spots were relatively homogeneous and their margin was clear. Observation of the adenoma and duodenitis revealed only whitish villi. Although the lymphangioma was indistinguishable from the follicular lymphomas by magnified features, it was easily diagnosed based on the macroscopic morphology. In conclusion, magnified endoscopic features, in combination with macroscopic features, are useful for differentiating follicular lymphomas from other duodenal diseases presenting whitish lesions. |

Abstract | A predictive marker of the rapid progression to hepatic failure is desired for patients with asymptomatic primary biliary cirrhosis (aPBC). We performed a systematic cohort analysis of 101 patients diagnosed as having aPBC and the rapid progression to liver failure in some, by focusing on cholestasis. Cholestasis was assessed by aberrant keratin7 (K-7) expressions in the patientsʼ hepatocytes. Intralobular expressions of K-7 were found in 9 of the 101 patients. The grades of K-7 expression were significantly associated with the levels of alanine aminotransferase, alkaline phosphatase, and total bilirubin at the time of diagnosis, but not with bile duct loss or cholestasis. Stepwise logistic regression analysis revealed that high grades of K-7 expression correlated positively with high levels of total bilirubin. During the follow-up period, 8 patients developed jaundice, and the mean period until the development of jaundice was 5.2 years. The proportional hazards models for the risk of developing jaundice identified a high grade of aberrant K-7 expression in hepatocytes as the only significant risk factor. Aberrant K-7 expression in hepatocytes can be used as an additional marker to predict rapid progression to liver failure in patients with aPBC at the time of diagnosis. |
