Aim: To evaluate bacterial resistance to clarithromycin and fluoroquinolones in Brazil using molecular methods.

Methods: The primary antibiotic resistance rates of Helicobacter pylori (H. pylori) were determined from November 2012 to March 2015 in the Southern, South-Eastern, Northern, North-Eastern, and Central-Western regions of Brazil.

The accidental swallowing of prosthetic devices has been discussed in the relevant literature as an unusual, although ordinary, event in clinical practice. This article aims at reporting the ingestion of an inter-occlusal device used to restore the Vertical Dimension of Occlusion (VDO) which, during the ingestion of an analgesic pill, was accidentally swallowed. The patient was sent to the Clinics Hospital UFMG where, upon taking radiographs, the device was located in the upper third of the esophagus.

Background: In cystic fibrosis (CF) patients a duodenal impaired bicarbonate secretion and unbuffered gastric acid are always described and the development of duodenal ulceration is uncommon (CF paradox). Helicobacter pylori (HP) infection is the main cause for duodenal ulceration and its prevalence in CF patients is controversial.

Aim: The objective of this study is to evaluate HP prevalence, gastric histology, and duodenal ulceration in adult FC patients.

Background: Proton pump inhibitors (PPI) are the drugs of choice for treatment of gastroesophageal reflux disease (GERD). Omeprazole, the first PPI commercialized, is now available in different formulations.

Objectives: To compare the efficacy of different omeprazole formulations on gastric acid secretion measured by intragastric and esophageal pH monitoring in patients with reflux esophagitis.

Background: Barretts esophagus, the major risk factor for esophageal adenocarcinoma, is detected in approximately 10%-14% of individuals submitted to upper endoscopy for the assessment of gastroesophageal reflux disease related symptoms. Prevalence studies of Barretts esophagus in individuals without typical symptoms of gastroesophageal reflux disease have reported rates ranging from 0.6% to 25%.

Unlabelled: Recent in vitro studies suggest that propolis and some of its phenolic components are able to inhibit Helicobacter pylori growth. To date, there are no clinical studies.

Aims: To evaluate the effect of Brazilian green propolis on H.

Background: Gastroesophageal reflux disease is a very common affection, and esophageal involvement is particularly frequent. The means to effectively control symptoms and improve esophageal inflammation in these patients is to reduce esophageal acid exposure. For this purpose, we use gastric proton pump inhibitor, that can suppress gastric acid secretion.
