A fatal case of malignant atrophic papulosis (Degos disease) with optic nerve and spinal cord involvement is described. Magnetic resonance imaging (MRI) of the optic nerve showed abnormal signal enhancement on fat suppressed T1 weighted images after intravenous meglumine gadopentetate infusion. On T2 weighted sagittal images, a sawtooth pattern was observed(More)
To examine the association between vibration-induced white finger (VWF) and hearing loss, 108 male forest workers who regularly used vibrating tools were followed up for five years. Case-control pairs matched for initial age and hearing level and exposure time to noise during the study period were selected from men with and without VWF. The hearing levels(More)
Many cases of choledocholiths formed around sutures and clips used during cholecystectomy have been reported. We describe a case of gallstone formation around a nylon suture after non-biliary surgery. To the best of our knowledge, this is the first report of such a case. A 75-year-old Japanese man, who had undergone distal gastrectomy for gastric cancer and(More)
We herein report a case of primary esophageal malignant melanoma in which the development from a preceding benign melanotic lesion and the growing process of the tumor were chronologically observed by serial endoscopic examinations. Biopsy specimens repeatedly taken from the tumor failed to identify the presence of malignant melanoma. A positron emission(More)
A 73-year-old man had undergone right hemicolectomy for advanced colon cancer in May 2006, and he concurrently had multiple liver metastases. After the operation, the patient was given chemotherapy with FOLFIRI. A partial response was achieved for twelve months, and then the liver tumors enlarged. Second-line chemotherapy with FOLFOX was delivered. After(More)
This paper proposes a relational version of the fuzzy c-means (FCM) classifier in which relational data instead of object data are used. The classifier based on the relational clustering is called "relational classifier". The classifier is useful when a feature space has an extremely high dimensionality that exceeds the number of objects and many of the(More)
