STUDY OBJECTIVES The effects of gastroesophageal reflux on airway hyperresponsiveness in patients with bronchial asthma have yet to be studied in significant detail. The purpose of the present study was to determine how esophageal acid perfusion could change airway responsiveness in patients with bronchial asthma. PATIENTS AND INTERVENTIONS In seven patients with bronchial asthma (mean +/- SD...

OBJECTIVE To assess risk factors for gastroesophageal reflux disease (GERD) in very low birth weight infants with bronchopulmonary dysplasia. METHODS A case-control study was carried out in 23 cases and 23 control subjects with bronchopulmonary dysplasia submitted to 24-hour esophageal pH monitoring between January 2001 and October 2005. Cases and controls were compared for gestational age, b...

Gastroesophageal reflux disease (GERD) is one of the most common diagnoses in a gastroenterologist's practice. Gastroesophageal reflux describes the retrograde movement of gastric contents through the lower esophageal sphincter (LES) to the esophagus. It is a common, normal phenomenon which may occur with or without accompanying symptoms. Symptoms associated with GERD include heartburn, acid re...

BACKGROUND/AIMS Functional constipation and gastroesophageal reflux disease are two major and commonly encountered components of childhood functional gastrointestinal disorders. Epidemiological studies in the adult population support that there is a significant overlap between the different functional disorders of the digestive tract. Therefore, we aimed to investigate the frequency of gastroes...

OBJECTIVES/HYPOTHESIS Oropharyngeal (OP) pH monitoring has been developed to detect supra-esophageal gastric reflux (SEGR). The results obtained with OP pH-metry and multichannel intraluminal impedance/pH monitoring (MII/pH) were compared. STUDY DESIGN Diagnostic study. METHODS Ten patients (age 46.33 ± 9.86 years) presenting with chronic coughing underwent simultaneous OP and MII/pH record...

BACKGROUND/AIMS Gastroesophageal reflux disease (GERD) is diagnosed based on symptoms of heartburn and regurgitation but is a heterogeneous condition which can be subclassified according to endoscopy and esophageal reflux monitoring. The aim of this study was to identify differences in demographic characteristics and reflux symptom patterns among patients with various spectrum of GERD. METHOD...

We report the case of a rare association between achalasia and Down syndrome in a child presenting with symptoms that suggest a gastroesophageal reflux. Evaluation of the patient with 24-hour multichannel intraluminal impedance and pH recording and upper endoscopy lead to the diagnosis of achalasia. However, the persistence of the symptoms after the concurrent surgical myomectomy and fundoplica...

BACKGROUND/AIMS We assessed the bolus transit and motility characteristics in gastroesophageal reflux disease (GERD) patients with abnormal esophageal pH monitoring. METHODS We retrospectively reviewed the combined impedance-esophageal manometry data from consecutive patients who had abnormal acid exposure during 24-hour esophageal pH monitoring. We compared these data to the results from fun...

Combined multichannel intraesophageal impedance-pH (MII-pH) monitoring is currently the the gold standard method to diagnosis of gastroesophageal reflux disease (GERD). A standard MII-pH catheter has six pairs of impedance electrodes. Multiple impedance-measuring within the esophagus allows determination of direction of bolus movement within the esophagus. So that MII is used as a good esophage...

STUDY OBJECTIVES The effect of gastroesophageal reflux (GER) on cough responsiveness in patients with bronchial asthma has yet to be studied in significant detail. The purpose of this study was to assess the effect of distal esophageal acid perfusion on cough responsiveness in patients with bronchial asthma. PATIENTS AND INTERVENTIONS In seven patients with mild persistent bronchial asthma (m...
