BACKGROUND Feeding device replacement is often required for long-term maintenance after initial percutaneous endoscopic gastrostomy or jejunostomy placement. Although there are several case reports on serious complications of gastrostomy device replacement, there are few reports of an overall analysis of the complications associated with feeding device(More)
The authors established a new experimental model of fulminant hepatic failure (FHF) with prolonged hepatocellular necrosis and impaired liver regeneration, and evaluated the immunological mechanisms related to the impaired liver regeneration in this model. A novel lipid A analogue, FS-112, was injected intravenously into male Balb/c mice, followed by a 70%(More)
BACKGROUND Aspiration is one of the major complications after percutaneous endoscopic gastrostomy (PEG). The administration of semi-solid nutrients by means of gastrostomy tube has recently been reported to be effective in preventing aspiration pneumonia. The effects of semi-solid nutrients on gastroesophageal reflux, intragastric distribution, and gastric(More)
BACKGROUND & AIMS Trace element deficiencies are known to occur during long-term enteral nutrition feeding. We compared the serum concentrations of trace elements between patients treated with gastrostomy and those treated with jejunostomy. METHODS Our subjects were 36 patients who underwent percutaneous endoscopic gastrostomy (PEG group) and 23 patients(More)
BACKGROUND It is difficult to predict whether or not gastroesophageal reflux (GER), such as aspiration or vomiting, will occur after PEG. OBJECTIVE To identify factors that would support the prediction of aspiration after PEG. DESIGN Case-control study. SETTING Patients who underwent PEG from February 1998 to June 2005 in our hospital. PATIENTS The(More)
PURPOSE To investigate the ability of patients with strabismus and/or amblyopia to see 3D images. METHODS A questionnaire survey conducted for children aged 6 to 19 years and adults aged 20 to 39 years on their experience of viewing 3D images (movies, motion attractions, television, games), asking whether they could see stereoscopically, with or without(More)
BACKGROUND Upper gastrointestinal (GI) hemorrhage after percutaneous endoscopic gastrostomy (PEG) is sometimes reported as one of the serious complications. Our purpose was to clarify the cause of upper GI hemorrhage after PEG. PATIENTS AND METHODS We retrospectively investigated the causes of upper GI hemorrhage among a total of 416 patients out of 426(More)
A 33-year-old man with epigastralgia was admitted. Upper gastrointestinal endoscopy revealed gastric fold hypertrophy, mucosal hemorrhage, and widespread erosion in the stomach and aphthoid erosion in the duodenum. The presence of intranuclear inclusion bodies positively stained with anti-cytomegalovirus antibody from the biopsy specimens indicated that the(More)
This presentation describes the Design Automation System (DAS-2) used in designing FACOM 230-series computers (such as FACOM 230-60, one of Japan's largest computers). Greatly assisting designers, DAS-2 lightens their workload in logic design, packaging design, and wiring design. It also provides manufacturing data required for automatic production and(More)
AIM To evaluate the inhibitory effects of carbon dioxide (CO(2)) insufflation on pneumoperitoneum and bowel distension after percutaneous endoscopic gastrostomy (PEG). METHODS A total of 73 consecutive patients who were undergoing PEG were enrolled in our study. After eliminating 13 patients who fitted our exclusion criteria, 60 patients were randomly(More)
