We report a case of two pseudolymphomas of the liver in a 63-year-old Japanese woman with primary biliary cirrhosis. One of the lesions was found incidentally during a medical examination, presenting as a 10 mm hypodense nodule that revealed hyperdensity in the early phase and hypodensity in the late phase in computed tomography (CT) after injection of(More)
Superficial non-ampullary duodenal epithelial tumor (SNADET) is defined as a sporadic tumor that is confined to the mucosa or submucosa that does not arise from Vater's papilla, and it includes adenoma and adenocarcinoma. Recent developments in endoscopic technology, such as high-resolution endoscopy and image-enhanced endoscopy, may increase the chances of(More)
Cortical somatosensory evoked potentials to posterior tibial nerve stimulation were obtained in 29 normal controls varying in age and body height. In obtaining these potentials we varied recording derivations and frequency settings. Our recordings demonstrated the following points: N20 (dorsal cord potential) and the early cortical components (P2, N2) were(More)
Spinal cord and subcortical brain stem evoked potentials had an amplitude at least 2 times higher when the cauda equina rather than bilateral peripheral nerves was stimulated. Cauda equina stimulation is indicated when potentials to peripheral nerve stimulation are absent or are too low in amplitude to permit reliable surgical monitoring. The technique is(More)
Although adrenomedullin (AM) is known to ameliorate inflammatory processes, few data exist regarding the effect of AM on inflammatory colitis. Therefore, we examined the effect of AM on inflammatory response in vitro and in vivo colitis model. In mice experimental colitis induced by 3% dextran sulfate sodium (DSS) in drinking water for 7 days, AM with(More)
BACKGROUND Laparoscopic and endoscopic cooperative surgery (LECS) is a minimally invasive surgical technique used to resect gastric submucosal tumors with intraluminal growth. Endoscopic submucosal dissection is used to determine the appropriate resection line from within the stomach lumen as it minimizes the stomach wall resection area and prevents(More)
BACKGROUND AND STUDY AIM Endoscopic submucosal dissection (ESD) is more difficult to perform for colorectal tumors, but the use of traction to facilitate direct submucosal layer visualization is a promising method to reduce procedure times and complication rates. This study aimed to evaluate the efficacy and safety of the clip and snare method (CSM) with a(More)
The effects of stimulus intensity on subcortical and cortical somatosensory evoked potentials (SEPs) to posterior tibial nerve (PTN) stimulation were studied in 16 normal controls. Stimulus intensity was evaluated as a function of sensory threshold (S). Motor threshold (M) varied between 1 S and 2 S. The amplitude of N18 (afferent volley immediately before(More)
Severe hypomagnesemia is a serious clinical condition. Proton pump inhibitor (PPI) induced hypomagnesemia has been recognized since 2006. In March 2011 the U.S. Food and Drug Administration advised that long-term use of PPI can induce hypomagnesemia. We report the first Japanese case of hypomagnesemia associated with chronic use of PPIs in a 64-year-old man(More)
OBJECTIVE Although many mutations of the Wilson's disease (WD) gene (ATP7B) have been reported, few data exist regarding the occurrence of fulminant hepatic failure (FHF). We sought to determine if genotypic assignment according to type of protein-product could be related to the prevalence of FHF among patients with WD. MATERIAL AND METHODS We performed(More)
