There have been few epidemiological studies on gastroenteropancreatic neuroendocrine tumors (GEP-NETs) in Japan. We examined the epidemiology of GEP-NETs [pancreatic endocrine tumors (PETs) and gastrointestinal neuroendocrine tumors (GI-NETs)] in Japan in 2005 using a nationwide stratified random sampling method. A total of 2,845 individuals received(More)
We conducted a nationwide survey to estimate the incidence of neuroendocrine gastrointestinal tumors (NETs) newly diagnosed in Japan from 2002 through 2004. Data on 1541 patients, 514 pancreatic endocrine tumors (PETs) and 1027 gastrointestinal carcinoids (GICs), were collected and analyzed. Nonfunctioning tumors (NF-PET) constituted 47.7% of PETs.

A rare case of primary hyperparathyroidism associated with primary aldosteronism and breast cancer is reported. A 44-year-old woman was admitted to our hospital to undergo surgical removal of breast cancer. She had hypertension with low serum potassium, and slightly but significantly elevated serum calcium levels. Further studies demonstrated an enlarged(More)
Relatively little is known for the differentiation and maturation process of human B cells to plasma cells. This is particularly important in reconstitution work involving transfer of autoantibodies. To address this issue, we transplanted human peripheral blood mononuclear cells (PBMC) directly into the spleen of irradiated NOD/SCID mice depleted of natural(More)
We report a case of diabetic mastopathy in an elderly woman with type 2 diabetes. The patient was a 69-year-old woman diagnosed with type 2 diabetes at the age of 33 years. She had been treated with insulin for 25 years, however, her blood glucose had been poorly controlled. She noticed bilateral breast lumps in September 2002. Mammography of the breast(More)
TO THE EDITOR: An association between colonic neoplasia and Barrett’s esophagus was first reported in 1985 but has not been supported by recent studies (1–5). To determine if this association was valid in a veteran population, a retrospective chart review was performed on all veterans with Barrett’s esophagus who underwent colonoscopy at a central New York(More)
Additional phase III multicenter clinical study was performed to investigate the efficacy, safety, and usefulness of somatostatin receptor scintigraphy using 111In-pentetreotide (MP-1727), which binds to somatostatin receptors. Forty patients were included in the study; Group A: 18 patients, gastrointestinal hormone producing tumors had been detected with(More)
Here, we report a case of acute liver dysfunction complicated with uncontrollable glycemia due to insulin antibody. The patient was admitted to our hospital due to diabetic ketoacidosis. He was administered insulin immediately, however, his fasting plasma glucose level remained unstable despite the insulin treatment. Blood biochemistry revealed severe liver(More)
OBJECTIVE To investigate the contribution of muscle afferents to tibial nerve somatosensory evoked potentials (SEPs). METHODS The left tibial nerve was stimulated at the knee and ankle in eight normal subjects. We tried to selectively stimulate Ia fibers from the calf muscles at the popliteal fossa by subtly changing the stimulation site while monitoring(More)
Cryptosporidium parvum infection has been recognized as one of the pathogens causing severe and persistent diarrhea in immunodeficient patients, such as those with AIDS, worldwide. However, in Japan, the frequency of this infection has been rare, except for environmental contamination through the water supply. In this communication, we describe a Japanese(More)
