The purpose of this observational study (this means that no drug is being tested in this study) is to obtain updated and detailed information about the Gastroesophageal Reflux Disease (GERD) specificities in European patients. The information about patients suffering from typical GERD symptoms will be collected in order to establish a classification of adult patients profile based on the characteristics of GERD symptoms. This study will only involve data collection about the disease. The treatment will not be affected by the study.

Histology Post-Endoscopic Eradication Therapy (EET)

Esophageal RefluxBarrett Esophagus

This study is looking at a cohort of patients who have undergone treatment for Barrett's Esophagus (BE) and who have experienced complete eradication of the disease. The aim of the proposed study is to evaluate the histologic features of the neosquamous epithelium (NSE) following complete eradication of intestinal metaplasia (CE-IM) in patients undergoing routine surveillance biopsies and compare these data to a direct measure of reflux using 24hr pH impedance, to determine the correlation between histology and persistent reflux. These data will allow us to more accurately risk stratify patients for recurrence of BE following EET.

Prevalence and Clinical Characteristics of Patients With Jackhammer Esophagus and Symptoms of Gastroesophageal...

Esophageal Motility Disorders

Gastroesophageal reflux disease (GERD) is involved in the development of esophageal motility disorders like Jackhammer esophagus (JE), a novel hypercontractile condition that was associated with progression to achalasia and limited outcomes following surgical anti-reflux therapy. This trial was designed to assess the prevalence and characteristics of JE in patients with typical symptoms of GERD and responsiveness to PPI therapy.

Thresholds of Straight Leg Raise Maneuver During High-Resolution-Manometry

Gastroesophageal Reflux

High resolution manometry (HRM) is a key test in the preoperative assessment of patients with gastro-esophageal reflux disease (GERD) who are potential candidates for antireflux surgery. The recent Lyon consensus suggested the potential usefulness of HRM in diagnosing GERD, however, sensitivity and specificity of HRM for GERD remains low (53.6% and 72.5% respectively). Among recently proposed provocative tests during manometry, a traditional maneuver (straight leg raise maneuver, SLR) appeared promising in predicting reflux. This is a multicenter study involving high-volume esophageal function laboratories around the world. Patients with suspected GERD and tested with HRM and pH-impedance will be asked to perform SLR during HRM. Intra-abdominal and intra-esophageal pressure during SLR will be recorded and compared with acid exposure time (AET) at pH-impedance. Primary aim is to determine the optimal threshold of intra-esophageal pressure augmentation during straight leg raise (SLR) maneuver that predicts pathological esophageal acid exposure time (AET). Secondary aim is to assess the diagnostic performance of HMR with SRL maneuver, calculating sensitivity, specificity, false-positive rate (FPR), false-negative rate (FNR), positive predictive value and total misclassification rate.

A Cross-sectional Study on the Prevalence and Extraesophageal Symptoms of Gastroesophageal Reflux...

Gastroesophageal Reflux Disease

The present study has been designed to provide current data on GERD prevalence in several regional areas of Greece outside the two major urban centres (Athens and Thessaloniki), to measure the treatment response in GERD patients, and to assess the correlations between the two methods of diagnosing GERD, i.e. reporting of symptoms by the patient to the physician and completion of the GerdQ questionnaire by the patient. Additionally, this study aims to provide data on the prevalence of extraesophageal symptoms in GERD patients in Greece. The XQS questionnaire will be applied for the identification of these patients and the assessment of the extraesophageal disease burden (frequency and intensity/severity). Finally, an association between the GerdQ and XQS scores will be attempted.

Prospective Pediatric Vesicoureteral Reflux Surgery Database

Vesicoureteral Reflux

The purpose of this research is to provide a clearer understanding of quality and outcomes for three types of surgical procedures performed at Connecticut Children's for treatment of vesicoureteral reflux. In order to consistently gather data over time, the investigators propose to establish database for surgical intervention for vesicoureteral reflux. Specific Aim 1: To consistently collect performance and outcomes data for the surgical treatment of vesicoureteral reflux in order to increase internal understanding of these procedures. Specific Aim2: To consistently collect performance and outcomes data for the surgical treatment of vesicoureteral reflux in order to perform more valuable clinical analysis for publication.

Relationship and Pathophysiology of Gastroesophageal Reflux and Dental/Periodontal Disease

Gastroesophageal RefluxDental Erosion

This study investigates the prevalence and pathophysiology of dental and periodontal involvement in pediatric patients with symptomatic or asymptomatic gastroesophageal reflux (GER) or gastroesophageal reflux disease (GERD). Primary objectives are to compare the prevalence of oral disease in children with and without a diagnosis or symptoms/signs of GERD in a cross-sectional study. Secondary objectives are to examine factors that might lead to the pathogenesis of the dental and periodontal lesions observed in this group of subjects. The primary hypothesis is to prove that children aged 10-18 years diagnosed with or having symptoms or signs of GERD have a significantly higher amount of dental erosions in comparison to a matched control group. Secondary hypotheses are that children aged 10 - 18 years diagnosed with or having signs of GER have higher DMFS (Decayed, Missing, Filled permanent tooth Surfaces) rates, higher SBI (Sulcus Bleeding Index) rates, worse Periodontal status, and lower saliva buffering capacity.
