BACKGROUND Bariatric operations have variable range of complications and postoperative benefits. Gastroesophageal reflux is considered potential factor that may result in damage to the esophageal mucosa and this subject is quite controversial in the literature. AIM To evaluate patients who underwent to Roux-en-Y gastrojejunal bypass correlating epidemiologic and endoscopic findings in pre and...

Erosive palmoplantar lichen planus (LP), also known as ulcerative or bullous LP, was first described by Cram et al. in 1966 as a rare variant of LP that can affect mucous membranes, palms, and soles. It presents clinically as erythematous, ulcerated plaques that run an extremely chronic course and are resistant to all types of treatment. The patient was an 84-year-old woman with a personal hist...

BACKGROUND Gastroesophageal reflux disease is a worldwide prevalent condition that exhibits a large variety of signs and symptoms of esophageal or extra-esophageal nature and can be related to the esophagic adenocarcinoma. In the last few years, greater importance has been given to the influence of physical exercises on it. Some recent investigations, though showing conflicting results, point t...

TO THE EDITOR: I appreciate the interest and comments on our paper, which was published in October 2013 issue of this journal. As you have commented, non-erosive reflux disease (NERD) is known as heterogeneous group from pathophysiological aspect. In our paper, NERD is defined as patients with typical symptoms of gastroesophageal reflux disease (GERD) such as heartburn or acid regurgitation wit...

The extrinsic sources for erosion-causing acids are primarily acidic beverages and foodstuffs. Effervescent tablets also contain organic acids (e.g. citric, tartaric, malic) in order to form carbon dioxide by contact with water – with the help of the carbonate salts of the tablets. To adequately inform patients about the possible erosive potential of effervescent tablets, this study was underta...

Objective This in situ study investigated the ability of a CPP-ACP chewing gum in preventing erosive enamel loss. Material and Methods: During three experimental crossover phases (one phase per group) of seven days each, eight volunteers wore palatal devices with human enamel blocks. The groups were: GI - Sugar free chewing gum with CPP-ACP; GII - Conventional sugar free chewing gum; and GIII -...

Superficial erosion is one of the main soil degradation agents and erosion rates estimations for different edaphicclimate conditions for the conventional models, as USLE and RUSLE, are expensive and time-consuming. The use of cesium antrophogenic radionuclide is a new methodology that has been much studied and its application in the erosion soil evaluation has grown in countries as USA, UK, Aus...

aim : this study aimed at determining the prevalence of hiatal hernia (hh) in patients with endoscopic erosive esophagitis (ee). background : gastro-esophageal reflux disease (gerd) is one of the most common problems all over the world. this may lead to erosive esophagitis. previous studies have demonstrated that hh has an important role in the pathogenesis of reflux disease. the rising prevale...
