Background/Aims Twenty-four-hour esophageal impedance and pH monitoring allows detection of all types of reflux episodes and is considered the best technique for identifying gastroesophageal refluxes. However, normative data for the Japanese population are lacking. This multicenter study aimed to establish the normal range of 24-hour esophageal impedance and pH data both in the distal and the p...

BACKGROUND Although antisecretory medications such as histamine type II receptor antagonists or proton pump inhibitors have been used to treat reflux oesophagitis, a considerable number of patients do not achieve complete mucosal healing or suffer from either sustained symptoms or ensuing complications, suggesting other damaging factors or impaired mucosal resistance are also involved in the pa...

BACKGROUND Gastroesophageal reflux disease is a common, chronic disease worldwide. The weekly prevalence of reflux in developed countriesis 10% to 48%. It has previously been reported as 5% in Asian countries, but new reports show a higher level in both Asian and Arab countries. In Iran, reflux has increased over the last two decades. There are few studies concerning the prevalence of refluxin ...

Background/Aims Little data exists about esophageal body dysmotility and reflux patterns in refractory gastroesophageal reflux disease (RGERD) patients off therapy. We aimed to evaluate effects of esophageal body dysmotility on reflux parameters in RGERD patients by combining impedance-pH monitoring and high-resolution manometry (HRM). Methods We retrospectively reviewed the impedance-pH data...

Background: To date, impact of varicocelectomy on semen parameters is controversial mainly because clear preoperative selection criteria of patients to be submitted to varicocele surgery are still lacking. A comprehensive review on varicocele pathophysiology, and indications to varicocelectomy according to controlled studies and methanalises from literature and the Guidelines of the Scientific ...

OBJECTIVE We evaluated clinical characteristics of primary vesicoureteral reflux (VUR) in infants in a 30-year period in Brazil with special reference to the relation of renal parenchymal damage to urinary tract infection and gender. MATERIALS AND METHODS From 1975 through 2005, 417 girls (81.6%) and 94 boys (18.4%) with all grades of reflux were retrospectively reviewed. Patients were catego...

Helicobacter pylori and duodenogastric reflux are both recognised as playing aetiological roles in chronic gastritis. This study investigated whether H pylori colonisation of the antral mucosa and duodenogastric reflux are independent phenomena or have a causal relationship. Thirty eight patients (15 men, 23 women) aged (mean (SD)) 48 (17) years participated. Each patient underwent gastroscopy....

Seventy-five children aged 3 weeks to 12 years and found on investigation of symptomatic urinary infection to have vesicoureteric reflux were managed conservatively with continuous low-dose prophylaxis. Serial cystographic and renal growth studies were performed during seven to 15 years' follow-up. Reflux disappeared spontaneously in 53 children (71%) and from 79% of the affected ureters. This ...

conclusions inter-rater accuracy could be improved at middle grades using renal ultrasonography (usg), which could promote communication between different specialists. results the intraclass correlation coefficient (icc) values ranging from 0.86 to 0.89 reflected good reliability. the lowest agreement was associated with middle grades (iii and iv). a marked difference in sensitivity was observe...
