The present study sought to establish a standard third-line eradication regimen for Helicobacter pylori in Japan. Subjects were 204 patients with H. pylori infection in whom the standard Japanese first- and second-line eradication therapies had proven unsuccessful. Patients were randomly assigned to one of the following third-line eradication therapy(More)
BACKGROUND AND AIM Intraluminally administered peppermint oil (PO) is reportedly a safe and useful antispasmodic for gastroscopy, colonoscopy and double-contrast barium enema. The aim of this study was to examine the efficacy of oral PO for double-contrast barium meal examination (DCBM) without other antispasmodics. METHODS Two hundred and five randomly(More)
Prophylactic treatment for esophageal varices has been performed without adequate supporting evidence. We assessed the feasibility of prophylactic and follow-up treatment for high-risk esophageal varices in patients with hepatocellular carcinoma (HCC). Patients with HCC were screened prospectively and followed up for esophageal varices and gastroduodenal(More)
AIM To determine the anti-inflammatory activity of probiotic Bifidobacteria in Bifidobacteria-fermented milk (BFM) which is effective against active ulcerative colitis (UC) and exacerbations of UC, and to explore the immunoregulatory mechanisms. METHODS Peripheral blood mononuclear cells (PBMNC) from UC patients or HT-29 cells were co-cultured with(More)
BACKGROUND AND AIM Research on gastric lesions developing in response to stress is essential to elucidating the pathogenesis of these lesions as well as the interplay with other factors, including Helicobacter pylori infection and non-steroidal anti-inflammatory drug use. Genes expressed individually or in sets, such as heat shock proteins, growth factors,(More)
BACKGROUND Whether or not eradicating Helicobacter pylori worsens reflux esophagitis remains controversial. We investigated the relationship between gastroesophageal flap valve grading and endoscopic reflux esophagitis (in patients with peptic ulcer and gastritis) before and after H. pylori eradication in a case controlled study. Whether endoscopic(More)
BACKGROUND/AIMS Schönlein-Henoch purpura (SHP) is a systemic condition characterized by purpura associated with leukocytoclastic vasculitis. SHP diagnosis is more difficult in infrequent cases where gastrointestinal (GI) symptoms precede purpura. This report examines 11 cases of SHP at our hospital with specific regard to the incidences and details of GI(More)
The purpose of the present study was to investigate the clinical usefulness of the detection of serum p53 antibodies (p53 Abs) in patients with oral squamous cell carcinoma (SCC). Preoperative values of p53 Abs were measured by enzyme-linked immunosorbent assay in 113 patients with primary oral SCC and seropositive patients were reevaluated postoperatively.(More)
OBJECTIVE Impaired butyrate metabolism plays a part in ulcerative colitis (UC). To assess the usefulness of measuring butyrate metabolism as an indication of inflammatory activity, we investigated the rate of butyrate metabolism by breath test after administering [1-(13)C]-butyrate rectally to patients with UC. MATERIAL AND METHODS Thirty-eight UC(More)
The etiology of Cronkhite-Canada syndrome (CCS) remains unknown and many cases are refractory to treatment. Therefore, new therapies are urgently needed. Furthermore, a number of CCS cases with gastrointestinal carcinoma have been reported. Our patient had rapid onset of CCS and early development of colon carcinoma associated with adenomas. High anterior(More)
