BACKGROUND AND AIMS The effect of metabolic risk factors on the natural course of gastro-oesophageal reflux disease (GORD), which remains elusive, was quantified. METHODS The population included 3669 subjects undergoing repeated upper endoscopy. Data were analysed using a three-state Markov model to estimate transition rates (according to the Los Angeles classification) regarding the natural ...

BACKGROUND/AIMS Obstructive sleep apnea is becoming more important in gastroesophageal reflux disease (GERD) patients. This study investigated the prevalence of high risk for obstructive sleep apnea in GERD patients in comparison with that in healthy controls using the Berlin Questionnaire. We also investigated the risk factors for obstructive sleep apnea in GERD patients. METHODS We enrolled...

Theoretical calculations have shown that acidic candies may be potentially erosive upon consumption. However, little is known about the protective effect of adding calcium to potentially erosive candies and about the protective effects of saliva that cannot be fully accounted for by theoretical calculations. Therefore, the aims of this study were to (1) determine the erosive potential of acidic...

INTRODUCTION Ineffective esophageal motility (IEM) is a frequent finding in patients with gastroesophageal reflux disease (GERD). It is responsible for delayed acid clearance as it affects esophageal emptying and saliva transport. Since erosive GERD is a more severe disease than nonerosive GERD, it may be associated with IEM, which delays esophageal clearance. Objective : We investigated the ro...

BACKGROUND/AIMS Researches on the potential risk factors for the development of erosive esophagitis have been conducted extensively, however, the results are conflicting. The aim of this multicenter study was to identify the prevalence rate and risk factors of erosive esophagitis and their interactions with residency status. METHODS A total of 4,023 eligible subjects at 8 tertiary health care...

OBJECTIVE Application of SnCl(2)/AmF/NaF containing mouth rinse showed good protection against erosion. The aim of the study was to evaluate if this is due to the amount of KOH-soluble fluoride (KOHsF) formed or its resistance under erosive conditions. METHODS One hundred and fifty bovine enamel samples were allocated to five groups (n = 30) and were once eroded in 0.05 mol/l citric acid (5 m...

Polyfibromatosis syndrome is a rare disease entity that is characterized by various clinical features such as palmar, plantar, and penile fibromatoses, keloid formations of the skin, and erosive arthropathy. Its precise pathophysiology or etiology remains unclear. In addition to distinctive diverse skin manifestations, patients with polyfibromatosis have been previously reported to show erosive...

The oral lichen planus (OLP) is a chronic inflammatory disease, probably autoimmune, with different clinical forms. The most common types are the reticular and the erosive ones. Apoptosis participates in the destruction of basal keratinocytes, but its role in the perpetuation of the subepithelial lymphocytic infiltrates was not yet investigated. To evaluate the involvement of apoptosis in the e...

OBJECTIVE This in vitro study assessed the anti-erosive effect of experimental mouthrinses containing TiF4 and NaF on dentin erosive loss. MATERIAL AND METHODS Bovine dentin specimens were randomly allocated into the groups (n=15): (1) SnCl2/NaF/AmF (Erosion Protection/GABA, pH 4.5, positive control); (2) experimental solution with 0.0815% TiF4(pH 2.5); (3) 0.105% NaF (pH 4.5); 4) 0.042% NaF+...
