Background/aims: Although risk factors of reflux esophagitis (RE) have been investigated in numerous cross-sectional studies, little is known about predictive factors associated with future onset of RE. We investigated time courses of clinical parameters before RE onset by a longitudinal case-control study using health checkup records.
Methods: We used health checkup records between April 2004 and March 2014 at 9 institutions in Japan.
Objective: Quality of life (QOL) impairment of patients who visit an outpatient clinic for abdominal symptoms has not been clarified. We investigated symptom-related QOL impairment that led patients to seek medical care.
Patients And Methods: Abdominal symptom-related QOL was determined using the Izumo scale instrument in 172 patients who visited a clinic for their abdominal symptoms and in 961 healthy subjects who attended an annual health check.
A 24-year-old female Japanese patient presented with remarkably long roots of retained deciduous anterior teeth and permanent anterior teeth in the upper and lower jaw. Four lower anterior teeth were extracted for esthetic reasons. The patient had no apparent clinical syndrome related to the teeth or jaw, nor did there appear to be a family history of this condition.

The administration of gabexate mesilate has been reported to be effective for the prevention for post-ERCP pancreatitis when given during and after the procedure. The aim of the present study was to investigate the preventive effect of the novel protease inhibitor ulinastatin on post-ERCP pancreatitis.

In addition to its acid-suppressing effect, the H2RA nizatidine also has a prokinetic action by suppressing acetylcholine esterase. The present multicenter, randomized controlled study was performed to investigate whether nizatidine is superior to famotidine, which does not suppress acetylcholine esterase activity, in maintenance therapy for erosive esophagitis.

The aim of the present study was to clarify whether there is any difference in the speed of symptom relief in patients with reflux esophagitis following the administration of these three proton pump inhibitors (PPI).
Methods: Eighty-five patients with erosive reflux esophagitis were randomized to receive 8 weeks of 20 mg of omeprazole (n = 30), 30 mg of lansoprazole (n = 25), or 20 mg of rabeprazole (n = 30) once a morning.
The location of calcitonin gene-related peptide (CGRP) receptors in the rat stomach has not been elucidated. It was recently reported that the CGRP receptor is formed when a calcitonin-receptor-like receptor (CRLR) and receptor activity modifying protein (RAMP) 1 are co-expressed on the cell membrane. The aim of this study was to determine the location and the role of CGRP receptors in the rat gastric mucosa.
