Abstract
BACKGROUND To assess the 5-year outcomes of patients undergoing Collis-Nissen gastroplasty for type III-IV hiatal hernia with short esophagus. STUDY DESIGN From a prospective observational cohort of patients who underwent antireflux surgery for type III-IV hiatal hernia between 2009 and 2020, those with short esophagus (abdominal length <2.5 cm) in whom a Collis-Nissen procedure was performed and reached at least 5 years of follow-up were identified. Hernia recurrence, patients' symptoms, and quality of life were assessed annually by barium meal x-ray, upper endoscopy, and validated symptoms and Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaires. RESULTS Of the 114 patients with Collis-Nissen gastroplasty, 80 patients who completed a 5-year follow-up were included (mean age 71 years). There were no postoperative leaks or deaths. Recurrent hiatal hernia (any size) was identified in 7 patients (8.8%). Heartburn, regurgitation, chest pain, and cough were significantly improved at each follow-up interval (p < 0.05). Preoperative dysphagia disappeared or improved in 26 of 30 patients, while new-onset dysphagia occurred in 6. Mean postoperative QOLRAD scores significantly improved at all dimensions (p < 0.05). CONCLUSIONS Collis gastroplasty combined with Nissen fundoplication provides low hernia recurrence, good control of symptoms, and improved quality of life in patients with large hiatal hernia and short esophagus.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD), which leads to acid reflux into the esophagus, is a common gastrointestinal disorder. Several studies have shown the prevalence of GERD in Iranian population, but their evidence is contradictory. Therefore, the present study was conducted to investigate the epidemiology of GERD in Iran. METHODS The entire steps of this systematic review and meta-analysis were based on the MOOSE protocol, and the results were reported accordance with the PRISMA guideline. This review is registered on PROSPERO (registration number: CRD42020142861). To find potentially relevant published articles, comprehensive search was done on international online databases Scopus, Science Direct, EMBASE, PubMed/Medline, CINAHL, EBSCO, Cochrane Library, Web of Science, Iranian online databases and the Google Scholar search engine in June 2019. Cochran test and I2 index were used to assess the heterogeneity of the studies. Data were analyzed using Comprehensive Meta-Analysis software ver. 2. The significance level of the test was considered to be P < 0.05. RESULTS The daily, weekly, monthly, and overall prevalence of GERD symptoms in Iranian population was 5.64% (95%CI [confidence interval]: 3.77-8.35%; N = 66,398), 12.50% (95%CI: 9.63-16.08%; N = 110,388), 18.62% (95%CI: 12.90-26.12%; N = 70,749) and 43.07% (95%CI: 35.00-51.53%; N = 73,189), respectively. The daily, weekly, monthly, and overall prevalence of heartburn in Iranian population was 2.46% (95%CI: 0.93-6.39%; N = 18,774), 9.52% (95%CI: 6.16-14.41%; N = 54,125), 8.19% (95%CI: 2.42-24.30%; N = 19,363) and 23.20% (95%CI: 13.56-36.79%; N = 26,543), respectively. The daily, weekly, monthly, and overall prevalence of regurgitation in Iranian population was 4.00% (95%CI: 1.88-8.32%; N = 18,774), 9.79% (95%CI: 5.99-15.60%; N = 41,140), 13.76% (95%CI: 6.18-44.31%; N = 19,363) and 36.53% (95%CI: 19.30-58.08%; N = 21,174), respectively. The sensitivity analysis for prevalence of all types GERD, heartburn and regurgitation symptoms by removing a study showed that the overall estimate is still robust. CONCLUSION The present meta-analysis provides comprehensive and useful information on the epidemiology of GERD in Iran for policy-makers and health care providers. This study showed a high prevalence of GERD in Iran. Therefore, effective measures on GERD-related factors such as lifestyle can be among the health policies of Iran.

Abstract
Background This study assessed the prevalence of gastroesophageal reflux disease (GERD) in a general adult population from Temuco in southern Chile. The association of GERD with demographic variables was also examined. Methods A cross-sectional study among the general population of Temuco in southern Chile was conducted in 2017, using a validated and reliable questionnaire for detecting GERD. The urban area of Temuco, with a population of 245,317 inhabitants (2002 census), was divided into four zones, which were representative of the socioeconomic sectors of the city. The sample size was estimated assuming a prevalence of 52.8%, an accuracy of 3.0%, a confidence level of 95.0%, and a design effect of 1.15. Area sampling was used to build clusters. The prevalence of GERD was determined and associated factors were studied by means of bivariate and multivariate analyses. Results A total of 1,069 subjects (47.9% women, median age 40 years) from the selected subareas were interviewed. The prevalence of GERD was 44.8%. The most frequently reported symptom was regurgitation (54.8%). One-third of subjects took medication to control symptoms and was considered 'sick' by the instrument, although >68% of them had never sought medical consultation. There was a significant association between GERD and age (P < 0.001) and female gender (P = 0.001). Conclusions In this population-based study, the prevalence of GERD was high (44.8%). GERD was associated with age and female gender.

Prevalence of Endoscopic Findings Before Bariatric Surgery and Their Influence on the Selection of the Surgical Technique. Obes Surg 2020; 30:4375-4380. [PMID: 32588172 DOI: 10.1007/s11695-020-04800-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Revised: 06/16/2020] [Accepted: 06/17/2020] [Indexed: 02/07/2023]
Abstract
PURPOSE Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are the two most popular procedures performed. The decision of which technique is most appropriate depends on the surgeon's preferences and experience. However, several factors strongly influence the decision of the procedure performed, including gastrointestinal disorders or asymptomatic upper gastrointestinal endoscopy (UGE) findings. This study aimed to describe the pathological endoscopic findings in morbidly obese patients undergoing preoperative routine UGE. MATERIALS AND METHODS A retrospective review of a prospectively collected database of all UGEs performed before bariatric surgery was performed. UGE was routinely performed to all the patients as part of the preoperative evaluation protocol. RESULTS A total of 790 patients were included. Surgical technique included 610 (77.2%) RYGB and 180 (22.8%) SG. Twenty-one asymptomatic patients presented esophagitis at UGE. In only seven patients (0.89%), the endoscopic findings of esophagitis had changed the initial surgical decision. The presence of ulcers or adenomatous or incompletely resected polyps was an indication for SG, to assure future endoscopic access in case it is needed. In 25 patients (3.17%), the initial operation would have been changed based on UGE findings. CONCLUSION Preoperative UGE allows the diagnosis of asymptomatic esophagitis related to gastroesophageal reflux disease and the identification of asymptomatic polyps and ulcers, with the potential ability for malignant transformation. In up to 3.17% of the cases, the endoscopic findings changed the operative strategy. As the complication rate associated with the procedure is low, we recommend the routine performance of preoperative UGE before bariatric surgery.

Abstract
OBJECTIVES The aim of the study was to evaluate acid and nonacid gastroesophageal reflux in infants and school-aged children with esophageal atresia (EA) using pH-impedance (pH-MII) monitoring. METHODS Between 2012 and 2017, all 24-hour pH-MII studies performed in infants (≤18 months) and 8-year olds with EA were included. Antiacid therapy was discontinued before study. Exclusion criteria were: isolated tracheoesophageal fistula; esophageal replacement therapy; tube feeding; and monitoring <18 hours. Automatically detected retrograde bolus movements (RBM) were manually reviewed and modified/deleted if necessary. RESULTS We included 57 children (51% boys; 2% isolated EA; 44% thoracoscopic EA repair): 24 infants (median age 0.6 years) and 33 school-aged children (median age 8.2 years). Of the automatically detected 3313 RBM, 1292 were manually deleted from the tracings: 52% of nonacid RBM and 8% of acid RBM (mainly misinterpreted swallows or 1 event recognized as several events). In infants, median reflux index (RI; pH <4) was 2.6% (abnormal in n = 2), median RBM was 61 (62% nonacid, 58% mixed), and median of the mean BCT was 11 seconds. In older children, median RI was 0.3% (abnormal in n = 4), median RBM was 21 (64% nonacid; 75% mixed), and median of the mean BCT was 13 seconds. CONCLUSIONS Most children with EA off medication have a normal RI, yet experience a significant number of nonacid RBM. After manual revision of the tracings, a high percentage of RBM was deleted. Our data show that automated impedance analysis software needs refinement for use in infants and children with EA and question the need for standard antiacid therapy in these patients.

Abstract
Gastroesophageal reflux disease (GERD) is a gastrointestinal motility disorder that results from the reflux of stomach contents into the esophagus or oral cavity resulting in symptoms or complications. The typical symptoms of GERD are heartburn and regurgitation of gastric contents into the oropharynx. GERD affects quality of life and may cause erosive esophagitis, esophageal strictures, and Barrett esophagus, a precursor to esophageal adenocarcinoma. GERD is a clinical diagnosis and is most effectively treated with proton-pump inhibitors (PPIs). Long-term use of PPIs is associated with bone fractures, chronic renal disease, acute renal disease, community-acquired pneumonia, and Clostridium difficile intestinal infection.

Abstract
BACKGROUND
Prevalence of gastroesophageal reflux disease (GERD) is increasing worldwide. We aimed to
estimate the prevalence of GERD in Pars Cohort Study (PCS) and to find its correlates.
METHODS
We used the baseline data from PCS. PCS was conducted in the district of Valashahr in Fars
province in southern Iran from 2012 to 2014. 9264 inhabitants who were 40-75 years old, and
agreed to participate were enrolled. Data were collected by a structured questionnaire and simple
physical examination of all participants.
RESULTS
Generally, 58.50% (95% CI 57.49 - 59.51) of the participants had GERD and 25.10% (95%
CI 24.22 - 25.99) experienced it at least weekly. Approximately, 32.0%, 52.0%, and 24.4% of the
participants reported heart burn sensation, regurgitation, and both symptoms, respectively. Being
female (OR: 1.45, 95% CI 1.27 - 1.65), being older (OR: 1.20, 95% CI 1.06 - 1.36), being divorced/
widowed/separated (OR: 1.38, 95% CI 1.01 - 1.91), and lower education (OR: 1.43, 95% CI 1.02 -
2.03) were associated with frequent GERD.
CONCLUSION
GERD is common in PCS and its prevalence is close to that in western countries. Being female,
higher age, being divorced/widowed/separated, lower education, history of hypertension, anxiety,
insomnia, and non-cigarette tobacco smoking were associated with frequent GERD. We are going to
investigate the causal relationship between these risk factors and GERD in the next stages of PCS.

Abstract
CONTEXT Gastroesophageal reflux disease (GERD) is a chronic condition that affects a growing number of people and is currently among the most common disorders seen in clinical practice. OBJECTIVE To develop a protocol for the management of GERD with osteopathic manipulative therapy (OMTh) applied to the diaphragm and esophagus, and to evaluate the protocol's effectiveness using the quality of life scale (QS-GERD) for the disease. METHODS In this single-blinded prospective study, an OMTh protocol focusing on the diaphragm and esophagus was applied to a single patient, who had received a diagnosis of GERD 4 years previously. Outcomes were measured using the QS-GERD, which has a total possible score ranging from 0 to 45 (the lower the score, the better the quality of life) and a level of satisfaction from very satisfied to incapacitated. The OMTh protocol was applied at 3 sessions (initial session, second session 1 week after the first, and third session 2 weeks after the second), and the patient completed the QS-GERD 4 times (before the first session, before the third session, and 2 and 4 weeks after the third session). RESULTS The OMTh protocol was administered without adverse events, and the patient reported positive outcomes after the third session. The QS-GERD showed a score improvement from 13 of 45 to 4 of 45. CONCLUSION The results in the present report show that OMTh applied to the diaphragm and esophagus may improve symptoms of GERD and should be added to the somatovisceral approach to the care of patients with this condition.

Abstract
GOALS To evaluate the association between metabolic syndrome (MetS) and risk of Barrett esophagus (BE) using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database compared with 2 control groups--Medicare population controls and endoscopy controls. BACKGROUND BE principally arises as an adaptation to the proinflammatory state induced by gastroesophageal reflux disease (GERD). The relationship between obesity and BE is presumed to be mediated by GERD. However, evidence suggests central adiposity also increases risk of BE independent of GERD. Central adiposity is one risk factor defining MetS, which confers a systemic proinflammatory state--a potential GERD-independent mechanism by which obesity could increase the risk of BE. STUDY MetS was defined as diagnosis of at least 3 of the following conditions: obesity, elevated triglycerides, high blood pressure, and elevated fasting glucose. Multivariable logistic regression was used to estimate adjusted odds ratios and 95% confidence intervals. RESULTS In 2198 incident BE cases, prior MetS was significantly associated with BE (odds ratio, 1.20; 95% confidence interval: 1.07, 1.36) compared with population controls. However, GERD status modified the association; among those without prior GERD, MetS increased risk of BE by 34%; however, no association was observed among those with a prior GERD diagnosis (P-value for effect modification <0.001). MetS was not associated with risk of BE compared with endoscopy controls. CONCLUSIONS MetS increased the risk of BE compared with population controls, an association driven by and confined to the non-GERD stratum. MetS may mediate an association between central adiposity and BE for those without GERD.

Abstract
BACKGROUND & AIMS Esophageal adenocarcinoma is believed to result from the progression of gastroesophageal reflux disease to erosive esophagitis and re-epithelialization of the esophagus with a columnar cell population termed Barrett's esophagus (BE). Men develop BE and esophageal adenocarcinoma more frequently than women, yet little is known about the mechanisms of this difference. We assessed whether sex steroid hormones were associated with BE in a male population. METHODS We analyzed data from the Barrett's Esophagus Early Detection Case Control Study, based at the Walter Reed National Military Medical Center. Blood samples were collected from 174 men with BE and 213 men without BE (controls, based on endoscopic analysis); 13 sex steroid hormones were measured by mass spectrometry and sex hormone binding globulin was measured by enzyme-linked immunosorbent assay. We also calculated free estradiol, free testosterone, and free dihydrotestosterone (DHT). We used multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) adjusted for age, race, smoking status, alcohol consumption, body mass index, heartburn, regurgitation, and gastroesophageal symptom score (excluding heartburn and regurgitation). RESULTS Levels of free testosterone and free DHT were associated positively with BE risk; patients in the highest quartile for these hormones were most likely to have BE (free testosterone: OR, 5.36; 95% CI, 2.21-13.03; P = .0002; free DHT: OR, 4.25; 95% CI, 1.87-9.66; P = .001). Level of estrone sulfate was associated inversely with BE risk (P for trend = .02). No other hormone was associated with BE risk. Relationships were not modified by age or BMI. CONCLUSIONS In an analysis of men, levels of free testosterone and free DHT were significantly associated with BE.

Abstract
BACKGROUND Barrett's esophagus (BE) is a metaplastic precursor lesion of esophageal adenocarcinoma (EA), the most rapidly increasing cancer in western societies. While the prevalence of BE is increasing, the vast majority of EA occurs in patients with undiagnosed BE. Thus, we sought to identify genes that are altered in BE compared to the normal mucosa of the esophagus, and which may be potential biomarkers for the development or diagnosis of BE. DESIGN We performed gene expression analysis using HG-U133A Affymetrix chips on fresh frozen tissue samples of Barrett's metaplasia and matched normal mucosa from squamous esophagus (NE) and gastric cardia (NC) in 40 BE patients. RESULTS Using a cut off of 2-fold and P<1.12E-06 (0.05 with Bonferroni correction), we identified 1324 differentially-expressed genes comparing BE vs NE and 649 differentially-expressed genes comparing BE vs NC. Except for individual genes such as the SOXs and PROM1 that were dysregulated only in BE vs NE, we found a subset of genes (n = 205) whose expression was significantly altered in both BE vs NE and BE vs NC. These genes were overrepresented in different pathways, including TGF-β and Notch. CONCLUSION Our findings provide additional data on the global transcriptome in BE tissues compared to matched NE and NC tissues which should promote further understanding of the functions and regulatory mechanisms of genes involved in BE development, as well as insight into novel genes that may be useful as potential biomarkers for the diagnosis of BE in the future.

Abstract
Background There have been very few reports assessing the relationship between various upper gastrointestinal (GI) symptoms or evaluating each individual upper GI symptom separately. Methods Based on the answers to Frequency Scale for the Symptoms of GERD from a large-scale population of healthy adults in Japan, a hierarchical cluster analysis was performed to categorize the typical 12 upper GI symptoms. The associations between the 12 symptoms and 13 background factors were systematically analyzed among the 18,097 digestive drug-free subjects, 364 proton-pump inhibitor (PPI) users, and 528 histamine H2-receptor antagonist (H2RA) users. Results The derived relationship between the 12 upper GI symptoms suggests the five symptom categories: heartburn (2), dyspepsia (4), acid regurgitation (3), pharyngo-upper esophageal discomfort (2), and fullness while eating (1). Among the digestive drug-free subjects, inadequate sleep, weight gain in adulthood, NSAID use, meals immediately prior to sleep, and frequent skipping of breakfast showed significant positive association with most upper GI symptoms. Compared to the digestive drug-free subjects, significantly associated factors for PPI and H2RA users are respectively different in “4 of 5” and “5 of 5” symptoms in heartburn and acid regurgitation categories, “1 of 2” and “1 of 2” symptoms in pharyngo-upper esophageal discomfort category, and “0 of 5” and “3 of 5” symptoms in dyspepsia and fullness while eating categories. These differences between digestive drug-free subjects and gastric acid suppressant users seem to correlate with our experiences in clinical situations: heartburn and acid regurgitation category symptoms are effectively controlled with PPI and H2RA whereas other category symptoms are not. Conclusions The 12 upper GI symptoms can be classified into five categories, which are statistically associated with various background factors. The differences of associated factors between digestive drug-free subjects and digestive drug users may be useful in studying the drug effects upon diverse upper GI symptoms.

Abstract
Numerous questionnaires with a wide variety of characteristics have been developed for the assessment of gastroesophageal reflux disease (GERD). Four well-defined dimensions are noticeable in these GERD questionnaires, which are symptoms, response to treatment, diagnosis, and burden on the quality of life of GERD patients. The aim of this review is to develop a complete overview of all available questionnaires, categorized per dimension of the assessment of GERD. A systematic search of the literature up to January 2013 using the Pubmed database and the Embase database, and search of references and conference abstract books were conducted. A total number of 65 questionnaires were extracted and evaluated. Thirty-nine questionnaires were found applicable for the assessment of GERD symptoms, three of which are generic gastrointestinal questionnaires. For the assessment of response to treatment, 14 questionnaires were considered applicable. Seven questionnaires with diagnostic purposes were found. In the assessment of quality of life in GERD patients, 18 questionnaires were found and evaluated. Twenty questionnaires were found to be used for more than one assessment dimension, and eight questionnaires were found for GERD assessment in infants and/or children. A wide variety of GERD questionnaires is available, of which the majority is used for assessment of GERD symptoms. Questionnaires differ in aspects such as design, validation and translations. Also, numerous multidimensional questionnaires are available, of which the Reflux Disease Questionnaire is widely applicable. We provided an overview of GERD questionnaires to aid investigators and clinicians in their search for the most appropriate questionnaire for their specific purposes.

Abstract
Gastroesophageal reflux disease is a diversity disease that affects life quality of people in the world. Due to the complicated pathogenesis and variations in clinical manifestations, there is still no true gold standard for GERD diagnosis, and it is still difficult to diagnose this disease in some patients. The proton pump inhibitor's diagnostic test (the PPI test) is noninvasive, of low cost, tied to treatment, and widely accepted. Our aim is to evaluate the diagnostic significance of coapplying a rabeprazole test with the SF-36 for GERD in this study. Our study shows that the SF-36 in combination with the rabeprazole test can screen GERD patients and increase the sensitivity and specificity of GERD diagnosis through reference to the change in SF-36 score before and after the treatment (65 in the trial).

Abstract
BACKGROUND Most patients with asthma are managed exclusively in primary care. Little is known about the patterns of airway dysfunction in these patients and how these relate to other aspects of the disease. AIMS We set out to assess this in a cross-sectional study of 262 patients. METHODS Symptoms, spirometry, airway responsiveness, reversibility, and airway inflammation were all assessed. Exacerbations requiring oral corticosteroids in the preceding year were enumerated. RESULTS Patients had heterogeneous patterns of airway dysfunction. Those with a post-bronchodilator forced expiratory volume in 1 sec/ forced vital capacity ratio of <0.7 had more exacerbations in the previous year (2.2 vs. 0.8; mean difference 1.4; 95% CI 0.4 to 2.4; p=0.007). Patients with normal results had less inflammation (proportion with a sputum eosinophil count of >1.9%, 20% vs. 48%, χ²=14.8, df=3; p<0.001) and fewer exacerbations (0.5 vs. 1.4; mean difference -0.9; 95% CI -1.4 to -0.4; p=0.001) but similar symptom scores (6.2 vs. 6.9; p=0.2) compared with patients with any abnormality. CONCLUSIONS Patients with a diagnosis of asthma have mixed patterns of physiological impairment; many have no airflow obstruction or airway hyper-responsiveness. The physiological characterisation of asthma is not related to symptoms and is of little value in predicting exacerbations or eosinophilic airway inflammation.

Abstract
Background/Aims To compare gastroesophageal reflux disease (GERD) symptoms and response to proton pump inhibitor (PPI) in patients with erosive esophagitis (EE), non-erosive reflux disease (NERD) or functional heartburn (FH) using GERD impact scale (GIS) questionnaire. Methods Total 126 patients with GERD symptoms were diagnosed as EE (n = 62), NERD (n = 34) and FH (n = 30) by endoscopy, 24-hour esophageal pH testing and Bernstein test, prospectively. Analysis of risk factors and GIS questionnaire for GERD symptoms and quality of life were performed before and 8 weeks after PPI treatment. Results EE group had a higher proportion of men, frequent alcohol consumption, smoking, hiatal hernia, body mass index ≥ 25 kg/m2 and triglyceride levels (≥ 150 mg/dL) than the other groups (all P < 0.05). On the other hand, both psychiatric treatment and psychopharmacotherapy were more frequent in patients with FH than in those with EE and NERD (both P < 0.05). Among GERD symptoms, chest pain was more frequent in FH group than in EE and NERD groups (P < 0.05). Eating problems and limitation of productive daily activities occurred frequently in FH group and NERD group, respectively. GIS after 8 week PPI treatment showed improvement in all of the GERD symptoms in EE (all P < 0.05) and in acid regurgitation, epigastric pain and hoarseness in NERD group (all P < 0.05). In terms of quality of life, PPI treatment improved sleep disturbance in EE (P = 0.031) and limitation of productive activity in the NERD group (P = 0.001). Conclusions GIS questionnaire showed that different characteristics and symptoms improved after PPI therapy among patients with EE, NERD and FH, demonstrating the usefulness of the GIS questionnaire.

Abstract
Gastroesophageal reflux disease (GERD) symptoms are best assessed using patient-reported outcome (PRO) instruments. Guidance on developing well-defined and reliable instruments that capture optimal information from the patient's perspective was recently published by the US Food and Drug Administration and the European Medicines Agency. The aim of this systematic review was to identify and evaluate existing PRO instruments for GERD symptoms with regard to regulatory requirements. Systematic literature searches were conducted in PubMed and Embase to identify PRO instruments for GERD symptoms that have undergone psychometric evaluation. Content, construct and test-retest reliability, internal consistency, and responsiveness were evaluated in relation to regulatory recommendations. Supplementary searches were conducted to assess whether identified instruments had been used as clinical trial endpoint measures. The systematic literature searches identified 15 PRO instruments for GERD symptoms that have undergone psychometric evaluation. Eight were designed to evaluate GERD symptoms, two were to diagnose GERD, four were designed for both evaluative and diagnostic purposes, and one was designed for screening purposes. Five instruments were developed and reported to include most steps recommended by the Food and Drug Administration and European Medicines Agency, and have also been used as endpoint measures in clinical trials: the GERD Symptom Assessment Scale, the Nocturnal Gastro-oesophageal Reflux Disease Symptom Severity and Impact Questionnaire, the Reflux Questionnaire, the Reflux Disease Questionnaire, and the Proton pump inhibitor Acid Suppression Symptom test. Existing PRO instruments for GERD do not meet all the regulatory requirements for an outcome instrument in reflux trials and may need further validation.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is a very common disorder worldwide, comprised of reflux esophagitis (RE) and non-erosive reflux disease (NERD). As more than half of GERD patients are classified into the NERD group, precise evaluation of bothersome epigastric symptoms is essential. Nevertheless, compared with many reports targeting endoscopic reflux esophagitis, large-scale studies focusing on GERD symptoms have been very scarce. METHODS To elucidate lifestyle factors affecting GERD symptoms, 19,864 healthy adults in Japan were analyzed. Sub-analyses of 371 proton pump inhibitor (PPI) users and 539 histamine H₂-receptor antagonist (H₂RA) users were also performed. Using the FSSG (Frequency Scale for the Symptoms of GERD) score as a response variable, 25 lifestyle-related factors were univariately evaluated by Student's t-test or Pearson's correlation coefficient, and were further analyzed with multiple linear regression modelling. RESULTS Average FSSG scores were 4.8 ± 5.2 for total subjects, 9.0 ± 7.3 for PPI users, and 8.2 ± 6.6 for H₂RA users. Among the total population, positively correlated factors and standardized coefficients (β) for FSSG scores are inadequate sleep (β = 0.158), digestive drug users (β = 0.0972 for PPI, β = 0.0903 for H₂RA, and β = 0.104 for others), increased body weight in adulthood (β = 0.081), dinner just before bedtime (β = 0.061), the habit of midnight snack (β = 0.055), lower body mass index (β = 0.054), NSAID users (β = 0.051), female gender (β = 0.048), lack of breakfast (β = 0.045), lack of physical exercise (β = 0.035), younger age (β = 0.033), antihyperglycemic agents non-users (β = 0.026), the habit of quick eating (β = 0.025), alcohol drinking (β = 0.025), history of gastrectomy (β = 0.024), history of cardiovascular disease (β = 0.020), and smoking (β = 0.018). Positively correlated factors for PPI users are female gender (β = 0.198), inadequate sleep (β = 0.150), lack of breakfast (β = 0.146), antihypertensive agent non-users (β = 0.134), and dinner just before bedtime (β = 0.129), whereas those for H₂RA users are inadequate sleep (β = 0.248), habit of midnight snack (β = 0.160), anticoagulants non-users (β = 0.106), and antihypertensive agents non-users (β = 0.095). CONCLUSIONS Among many lifestyle-related factors correlated with GERD symptoms, poor quality of sleep and irregular dietary habits are strong risk factors for high FSSG scores. At present, usual dose of PPI or H₂RA in Japan cannot fully relieve GERD symptoms.

Abstract
Questionnaire based assessment scales for gastroesophageal reflux disease (GERD) have been utilized for assessment of the patient's symptomatology, assessment of symptom severity and frequency, assessment of health-related quality of life and for assessment of response to treatment. A multitude of unidimensional and multidimensional questionnaires exist for making symptom assessment and monitoring quality of life in GERD. Many of the scales meet some of the parameters of an ideal evaluative GERD specific assessment instrument. Yet, there are certain shortcomings and challenges which are faced in development of GERD questionnaires. This review discusses the features of an ideal symptom assessment instrument, examines the strengths and weaknesses of currently available questionnaires.

Abstract
OBJECTIVES Gastroesophageal reflux disease (GERD) is a well-recognized consequence of congenital diaphragmatic hernia (CDH). Results of studies examining predictive factors for early and late GERD are inconclusive. The aim of this study was to assess the incidence of early (<2 years) and late GERD (≥6 years) following CDH repair and to identify predictive variables. PATIENTS AND METHODS Of 183 patients born with high-risk CDH, 107 survived and 38 were excluded. Perinatal and postnatal data of 69 eligible patients were analysed to identify variables predictive for early GERD. For the follow-up study, 58 patients (84%) (ages 12.1 ± 3.4 years; range 6-17) completed a standardised questionnaire. Results were compared with those from a healthy control group (n = 83). Patients who had a score indicating increased risk of GERD underwent further diagnostic assessment. Predictive factors for early and late GERD were identified using multivariate regression analysis. RESULTS Early GERD was demonstrated in 27 patients (39%). Patch closure and intrathoracic position of the stomach were independent predictive variables for early GERD. At the time of follow-up, 9 of 58 patients (16%) had symptoms suggestive of GERD. In 7 patients (12%), late GERD was confirmed. For late GERD, however, no perinatal or postnatal risk factors were identified. CONCLUSIONS Early GERD is more common in CDH patients with patch closure or intrathoracic position of the stomach. Predictive factors for late GERD could not be identified and screening for early GERD does not protect for future GERD; therefore, long-term follow-up for GERD in CDH survivors is mandatory.

Abstract
The incidence of gastroesophageal reflux disease (GERD) is increasing year by year. Currently, many methods are available for detection of GERD. Traditional detection methods, such as the reflux disease questionnaire and proton pump inhibitor test, are convenient and effective and can be used for primary screening of GERD. Endoscopy, chromoendoscopy, and magnification endoscopy have also been used widely in clinical detection of GERD. The usage of narrow-band imaging endoscopy, light-induced fluorescence endoscopy and confocal endoscopy offers new insight into the esophageal appearance of Barrett's esophagus and non-erosive reflux disease. Endoscopic optical coherence tomography and frequency-domain angle-resolved low-coherence interferometry are optical biopsy techniques that will be used gradually in clinical practice. The 24-hour esophageal pH monitoring, bile reflux monitoring, and esophageal manometry are the most commonly used method for monitoring gastroesophageal reflux but can not be used to monitor all reflux events. The 24-hour multichannel intraluminal impedance measurement and high-resolution manometry can redeem the shortage of the above detections and have been used gradually in clinical diagnosis. In this paper, we review the advances in methodology for detection of GERD.

Abstract
BACKGROUND There is a need for a practical instrument to screen for gastro-oesophageal reflux disease (GORD) in epidemiological studies. OBJECTIVES To develop a practical score to detect GORD and compare assessment of both symptom frequency and severity with frequency alone. METHODS One hundred patients with upper gastrointestinal symptoms and 150 volunteers with no such past history faced an interviewer-administered questionnaire assessing seven symptoms, graded for frequency and severity. Two scores were generated. Score 1, the sum of frequency of symptoms and score 2, the sum of products of frequency and severity of each. Internal consistency, test-retest reliability and criterion validity against 24-h pH monitoring were assessed. Cut-off scores were generated by receiver operating characteristic curves using scores of half the volunteers and patients selected randomly and validated on the other half. RESULTS Cut-off scores and area under the curve for score 1 were >/=10.5 and 0.93, and score 2 were >/=12.5 and 0.93, respectively. The sensitivity and specificity of diagnosing the disease in the remaining participants using score 1 was 89.7 and 92.4% and score 2 was 93.8 and 94.0%, respectively. The instrument had good internal consistency (Cronbach alpha = 0.73) and reliability (intraclass correlation coefficient of scores 1 and 2 were 0.94 and 0.95, respectively). Score 2 showed better correlation with 24-h pH monitoring parameters (Spearman's rank correlation, P = 0.01). CONCLUSION Our score is valid, reliable and can detect GORD with high sensitivity and specificity. A score assessing both frequency and severity of symptoms correlates better to an objective measure of GORD.

Abstract
AIM Following surgical correction in the neonatal period, patients born with oesophageal atresia have significant co-morbidity, particularly in childhood. This study evaluates health-related quality of life and its determinants such as concomitant anomalies and the presence of respiratory and/or gastro-intestinal symptoms 6-18 years after repair of oesophageal atresia. METHODS Parents of 24 patients with oesophageal atresia completed the child health questionnaire for parents and 37 patients completed the child form. Gastro-intestinal symptoms were assessed by a validated standardized reflux questionnaire. Results were compared with a healthy reference population. RESULTS Parents as well as patients themselves scored significantly lower on the domain general health perception. According to parents, general health perception was negatively affected by age at follow-up and concomitant anomalies. Patients reported that reflux symptoms reduced general health perception. CONCLUSION In this first study describing health-related quality of life in children and adolescents born with oesophageal atresia, we demonstrated that general health remains impaired because of a high incidence of concomitant anomalies and gastrointestinal symptoms in patients with oesophageal atresia when compared with the healthy reference population.

Abstract
BACKGROUND Gastro-oesophageal reflux disease (GERD) and dyspepsia affect 25-40% of the general population. In the absence of alarm symptoms, the current recommended policy in young dyspeptic patients is a 'test and treat' strategy for Helicobacter pylori; in GERD patients, a therapeutic trial with proton pump inhibitors is the treatment of choice. AIM To create a short and simple clinical algorithm, for the diagnosis and treatment of patients with upper gastrointestinal complaints. METHODS The clinical usefulness and cost-effectiveness of the new algorithm were evaluated in a controlled clinical trial, held in primary-care clinics in Israel. Clinical and economical treatment outcomes were evaluated after 1, 3 and 6 months comparing doctors who used the algorithm (cases) vs. those who did not (controls). RESULTS 78 cases and 54 controls completed the 6 months of follow up. The improvement in symptom severity and quality of life was greater in the cases than in the controls (P < 0.05). General practitioner clinics visits (P = 0.04), gastroenterology clinics visits (P = 0.02) and medication costs (P = 0.004) were all significantly reduced among cases. Controls underwent also more imaging tests (computerized tomography, ultrasound and X-ray) and endoscopies. The average cost for 6 months' treatment and follow-up was $US 199 for cases compared with an average of $US 336 in the control group. CONCLUSION The use of a clinical decision-support tool can facilitate and promote the implementation of management guidelines by general practitioners. The short algorithm presented in the study was found to be useful and easy to apply in clinical practice. Its effectiveness can be further increased by implementing it in computerized medical systems.

Abstract
Gastroesophageal reflux disease (GERD) is a common condition, managed mostly in primary care practice. Heartburn and acid regurgitation are considered primary symptoms, and are usually highly specific. However, the symptom spectrum is much wider and in many cases it is difficult to determine whether the patient has GERD or dyspepsia from another origin. The aim of this study is to develop a symptom score and rule for the diagnosis of GERD, using data mining techniques, to provide a clinical diagnostic tool for primary care practitioners in the evaluation and management of upper gastrointestinal symptoms. A diagnostic symptom questionnaire consisting of 15 items and based on the current literature was designed to measure the presence and severity of reflux and dyspepsia symptoms using a 5-point Likert-type scale. A total of 132 subjects with uninvestigated upper abdominal symptoms were prospectively recruited for symptom evaluation. All patients were interviewed and examined, underwent upper gastrointestinal endoscopy, and completed the questionnaire. Based on endoscopic findings as well as the medical interview, the subjects were classified as having reflux disease (GERD) or non-reflux disease (non-GERD). Data mining models and algorithms (neural networks, decision trees, and logistic regression) were used to build a short and simple new discriminative questionnaire. The most relevant variables discriminating GERD from non-GERD patients were heartburn, regurgitation, clinical response to antacids, sour taste, and aggravation of symptoms after a heavy meal. The sensitivity and specificity of the new symptom score were 70%-75% and 63%-78%, respectively. The area under the ROC curve for logistic regression and neural networks were 0.783 and 0.787, respectively. We present a new validated discriminative GERD questionnaire using data mining techniques. The questionnaire is useful, friendly, and short, and therefore can be easily applied in clinical practice for choosing the appropriate diagnostic workup for patients with upper gastrointestinal complaints.

Abstract
BACKGROUND Symptoms of gastro-oesophageal reflux disease have a substantial impact on patients' everyday lives. AIM To develop and test a short questionnaire to aid patient-doctor communication. METHODS The Gastro-oesophageal Reflux Disease Impact Scale was developed from a systematic literature review, focus groups of patients and primary care physicians, and patient cognitive interviews. A psychometric validation study was conducted based on two consultations in new (n = 100) or chronic (n = 105) gastro-oesophageal reflux disease patients. RESULTS The Gastro-oesophageal Reflux Disease Impact Scale demonstrated internal consistency (Cronbach's alpha ranged from 0.68 to 0.82), reproducibility (intraclass correlation coefficient in stable patients ranged from 0.61 to 0.72) and construct validity (Spearman correlations with Quality of Life in Reflux and Dyspepsia instrument and Reflux Disease Questionnaire: 0.5-0.8 in both patient groups). Effect sizes in new and chronic gastro-oesophageal reflux disease patients ranged from 0.9 to 1.5 and 0.32 to 0.42, respectively. Doctors reported altering their treatment decision based on information provided by the Gastro-oesophageal Reflux Disease Impact Scale in 35% of patients, and 77% of doctors found it to be useful. CONCLUSIONS The Gastro-oesophageal Reflux Disease Impact Scale demonstrated good psychometric properties in newly diagnosed gastro-oesophageal reflux disease patients and those already receiving treatment. This simple communication tool is a useful aid for managing primary care patients with gastro-oesophageal reflux disease.

Abstract
INTRODUÇÃO: Estudos têm demonstrado ser a doença do refluxo gastroesofágico capaz de alterar a qualidade de vida e a produtividade no trabalho dos doentes por ela acometidos. Instrumentos para esse tipo de avaliação são provenientes, em sua maioria, de países de língua inglesa e/ou francesa. A utilização desses instrumentos em nosso meio demanda criterioso processo de tradução e validação. OBJETIVOS: Traduzir para língua portuguesa os questionários GERD-HRQL (Gastroesophageal Reflux Disease - Health Related Quality of Life), HBQOL (Heartburn Specific Quality of Life Instrument) e GSAS (Gastroesophageal Reflux Disease Symptom Assessment Scale) específicos para avaliação de qualidade de vida na doença do refluxo gastroesofágico. Testar suas propriedades psicométricas de confiabilidade e validade. MÉTODOS: Cento e trinta e dois pacientes com doença do refluxo gastroesofágico (idade média 54,9 anos, ± DP 13,9) atendidos no ambulatório de motilidade digestiva da Universidade Federal de São Paulo, SP, e de gastrocirurgia da Faculdade de Medicina de São José do Rio Preto, SP, aceitaram participar do presente estudo, fornecendo termo de consentimento pós-esclarecimento. Destes, 40 pacientes participaram da fase de pré-teste (28 do sexo feminino e 12 do sexo masculino, com idade média de 55,3 anos, ± DP 14,7) e 92 da fase de validação (64 do sexo feminino e 28 sexo masculino, com idade média 54,7 anos e ± DP 13,7). A tradução e adaptação cultural foi realizada de acordo com o método de GUILLEMIN et al., sendo a validação dos questionários traduzidos (GERD-HRQL, HBQOL e GSAS) realizada em relação aos instrumentos genérico SF-36 e sintomático ESDRGE (SQGERD). RESULTADOS: A adaptação cultural implicou na troca de quatro palavras no GERD-HRQL, seis no HBQOL e nove no GSAS. Posteriormente a esta fase, o questionário GSAS foi abandonado por problemas no cálculo do escore, sendo as propriedades de medidas testadas nos dois questionários remanescentes, esses se mostraram reprodutíveis para uso inter e intra-observador com valores de 0,980 e 0,968, respectivamente, para o GERD-HRQL, e valores que variaram de 0,868 a 0,972, respectivamente, para o HBQOL. O questionário HBQOL demonstrou alta consistência interna (>0,70) para três das quatro dimensões avaliadas (aspecto físico, dor, sono). Os resultados encontrados na fase de validação apresentaram bons níveis de correlação com os questionários SF-36 e ESDRGE (SQGERD). CONCLUSÕES: As versões para a língua portuguesa (Brasil) dos instrumentos GERD-HRQL e HBQOL, adaptadas ao padrão cultural brasileiro, configuram-se em opções válidas, confiáveis, com baixo nível de desgaste do paciente e de fácil aplicação para avaliação de qualidade de vida na DRGE em nosso meio. O instrumento HBQOL é a única opção de avaliação multidimensional de qualidade de vida atualmente disponível para uso no Brasil. A versão em português do instrumento GSAS mostrou-se inadequada para avaliação de qualidade de vida na DRGE em nosso meio.

Abstract
BACKGROUND Symptom diaries are potentially attractive but, because of concerns about patient compliance, they have had limited use in clinical trials. We assessed the validity and responsiveness of a symptom diary for patients with gastro-oesophageal reflux disease. METHODS We included 215 patients with gastro-oesophageal reflux disease after starting treatment for 4 weeks with 40 mg esomeprazole once daily. Patients recorded whether they experienced night-time heartburn (yes/no), the severity of daytime heartburn on a scale from 1 (no heartburn) to 4 (severe heartburn) and their antacid use. Patients also completed a number of disease-specific and preference-based Health-related Quality of Life questionnaires at baseline and follow-up. RESULTS Consistent with a priori predictions, daytime heartburn showed moderate to strong correlations with the Quality of Life in Reflux and Dyspepsia questionnaire (0.36-0.67) and four scales of symptom severity (0.36-0.70) for baseline, follow-up and change scores, but low correlations with the Standard Gamble. Responsiveness of the daytime heartburn item was excellent with a mean change from baseline to follow-up of -1.3 (95% CI -1.4 to -1.1) and a standardized response mean of 1.33 while responsiveness of the daily antacid use item was moderate (mean change scores -1.8 tablets taken, 95% CI -2.3 to -1.3 and standardized response mean of 0.64). CONCLUSIONS The excellent psychometric properties of this simple gastro-oesophageal reflux disease diary make it an attractive measure for future trials.

Abstract
The nicotine dependence syndrome scale (NDSS) is a new multi-dimensional measure of nicotine dependence, yielding five scores for different aspects of dependence as well as a total score. In this study, we tested the NDSS in a young adult sample (mean age=24), using an extreme-groups comparison between non-dependent smokers (chippers, n=123) and regular smokers (n=130). Scores on each NDSS subscale strongly discriminated between the groups, with the NDSS-total discriminating them almost perfectly. The subscales were generally independent discriminators, demonstrating the discriminant validity of the subscales. NDSS scales also discriminated levels of intake and dependence within the chippers group, suggesting that the scales were sensitive to individual differences even at the very low end of the dependence continuum.

Abstract
BACKGROUND AND AIMS This study estimated the prevalence and clinical spectrum of gastroesophageal reflux disease (GERD) in Asan-si, Korea, as the prevalence is believed to be lower than in Western countries. METHODS A cross-sectional survey, using a reliable and valid questionnaire, was performed on randomly selected 2,240 Asan-si residents aged between 18 and 69 yr. All respondents were interviewed at their homes or offices by a team of interviewers. RESULTS Of the 1,902 eligible subjects, 1,417 (78.4%: male 762; female 655) were surveyed. The prevalence of heartburn occurring at least once a month, at least once a week, and at least twice a week was 4.71% (95% confidence interval (CI), 3.6-5.8), 2.0% (95% CI, 1.2-2.7), and 1.3% (95% CI, 0.7-1.9), respectively. The corresponding figures for acid regurgitation were 4.4% (95% CI, 3.3-5.5) and 2.0% (95% CI, 1.3-2.8), respectively. The prevalence of GERD, defined as heartburn and/or acid regurgitation experienced at least weekly, was 3.5% (95% CI, 2.6-4.5). No significant difference was detected between sexes. The prevalence of heartburn was associated with increasing age (p < 0.001). Nineteen percent of our population reported at least one of the atypical symptoms, for instance, chest pain, dysphagia, globus sensation, asthma, bronchitis, pneumonia, or hoarseness. The frequency of frequent GERD among subjects reporting any of the atypical symptoms was 12.6%, which was higher than that of the subjects without atypical symptoms. Patients with typical reflux symptoms were more common among those with atypical symptoms, compared to those without such symptoms (p < 0.001). Using a logistic regression model after adjusting for age and sex, typical reflux symptoms were associated with chest pain (odds ratio (OR), 9.3; 95% CI, 5.9-14.7), dysphagia (OR, 6.4; 95% CI, 2.8-14.7), globus sensation (OR, 3.9; 95% CI, 1.5-9.7), hoarseness (OR, 4.3; 95% CI, 1.4-13.1), asthma (OR, 2.6; 95% CI, 1.4-4.8), and bronchitis (OR, 1.2; 95% CI, 0.6-2.3). CONCLUSION The prevalence of GERD was 3.5% in this Korean population. Heartburn and acid regurgitation were significantly associated with chest pain, dysphagia, globus sensation, hoarseness, and asthma.

Abstract
UNLABELLED Symptoms of gastroesophageal reflux disease (GERD) are common in infants. It is often difficult to discriminate between physiological and pathologic gastroesophageal reflux, although this discrimination is essential to determine which infants to evaluate and treat. OBJECTIVES To identify the prevalence of reflux symptoms in infants and to evaluate the predictive value of a questionnaire and the correlation between pH study, histology and clinical score. METHODS Parents of 100 unselected infants visiting the well-baby clinic and 100 infants suspected of having gastroesophageal reflux disease were asked to fill in a 35-item questionnaire. A validated score, the Orenstein I-GERQ, was applied for selected questions. All infants suspected of having gastroesophageal reflux disease underwent prolonged esophageal pH monitoring and 44 or 100 underwent upper gastrointestinal tract endoscopy with esophageal biopsy. RESULTS Parents of infants with suspected gastroesophageal reflux disease reported significantly more regurgitation (68% versus 45%, P < 0.05) and crying (51% versus 20%, P < 0.01) compared with the parents of healthy infants. A pathologic pH study (reflux index > 10%) was found in 21 of 100 (21%) infants and was significantly associated only with pneumonia, apnea with fussing (P = 0.013 for both), defecation less than once a day (P = 0.033) and constipation (P = 0.05). Esophagitis was present in 17 of 44 (39%) and no one question was found to be significantly predictive. 38% of infants with a pathologic pH study had a normal esophageal biopsy and 53% of infants with histologic esophagitis had a normal pH study. Discordance between pH study and biopsies occurred in 14 of 44 (32%) patients. The Orenstein I-GERQ cut-off score failed to identify eight of 31 (26%) infants with gastroesophageal reflux disease. Conversely, the score was positive in 17 of 22 (81%) infants with normal biopsy and pH study and in 14 of 47 (30%) infants with normal pH study. CONCLUSIONS Clinical symptoms, histology and pH study show poor correlation in infants. Clinical symptoms such as regurgitation and crying are less frequent in unselected infants than in infants suspected of gastroesophageal reflux disease. However, questionnaires are poorly predictive for the severity of gastroesophageal reflux disease, as they do not correlate with esophageal acid exposure as measured by pH-metry and with esophagitis as evaluated by histology of esophageal biopsies.

Abstract
OBJECTIVE We describe the validation of a German-language version of the Reflux Disease Questionnaire in what is the first validation study of this patient questionnaire for a non-English speaking population. Gastro-oesophageal reflux disease is one of the most common diseases in primary care and has a significant negative impact on patients' quality of life. There is no gold standard for diagnosing gastro-oesophageal reflux disease, however, so the valid assessment of symptoms is especially important. DESIGN AND METHODS A total of 5689 patients (92%) completed the questionnaire both before treatment and after 2 weeks. The results were tested for validity and reliability. Predictive validity was tested in a pilot study of 100 patients. Convergent validity was examined using the Quality of Life in Reflux and Dyspepsia Questionnaire for the assessment of disease-specific quality of life and the McMaster Overall Treatment Evaluation for the assessment of therapeutic success. RESULTS Principal component analysis suggested a three-factor solution with the subscores heartburn, regurgitation, and dyspepsia. The internal consistencies of the subscores were between 0.84 and 0.86. Item difficulty ranged from 0.33 to 0.53, and corrected item-total correlation from 0.66 to 0.72. Effect sizes were between 0.8 and 1.0. CONCLUSION The German version of the questionnaire has good psychometric properties and is responsive to changes in health. Thus, we conclude that the German Reflux Disease Questionnaire is suitable for the assessment of heartburn, regurgitation, and treatment response, both in primary care settings and clinical studies.

Abstract
BACKGROUND The purpose of our study was to develop a quality-of-life (QoL) questionnaire for patients with gastroesophageal reflux disease (GERD) who have undergone laparoscopic fundoplication. This questionnaire was developed to be more comprehensive than existing measures. METHODS Between 1994 and 2002, 252 patients underwent laparoscopic fundoplication for GERD in the 1st Department of Surgery, Semmelweis University. We undertook a retrospective analysis: each of 252 operated patients was given a questionnaire and was requested to complete it and return it in an enclosed envelope. A total of 116 patients returned completed questionnaires. The patients included 55 men and 61 women, with a mean age of 46 years (range 14-77). These patients were used in the psychometric evaluation. The questionnaire consisted of 50 questions (including the Visick score, EORTC-QLQ-C30, and a modified GERD-HRQL). RESULTS Internal consistency reliability was high (alpha value overall, 0.95, range, 0.74-0.96). Using convergent and divergent validity, construct validity was evaluated by examining Pearson correlation coefficients between items and scales. Construct validity was demonstrated based on observed correlations. Known groups validity was upheld because patients who experienced more symptoms and patients who has higher Visick scores reported worse QoL than those with less symptoms or lower Visick scores. CONCLUSIONS Our questionnaire is a short and user-friendly instrument with excellent psychometric properties. It has been found to be valid and reliable.

Abstract
Population-based data regarding the prevalence of gastroesophageal reflux disease (GERD) in Turkey is lacking. Therefore, a valid and reliable instrument for population-based study of GERD is important. The purpose of the study is to establish the feasibility, reproducibility, reliability and validity of the Turkish version of the GERD questionnaire. The study sample of 630 people was randomly recruited from the 20- to 65-year-old-population of Menderes, Izmir. Face to face interviews were conducted using the Turkish GERD questionnaire. The questionnaire was translated into Turkish, and then test-retest reliability of the study was carried out with 25 individuals. Internal reliability was measured using Cronbach's alpha. Additionally, a validity study was performed at the gastroenterology outpatient clinic at Ege University, Faculty of Medicine (45 people). This Turkish GERD questionnaire was easily understood and completed in a reasonable time by members of the population for whom the survey was intended. For all questions (omitting the demographic questions) kappa statistics were calculated; the median kappa for the outpatient assessment was 0.82. The sensitivity of the questionnaire concerning heartburn was strong and the specificity of the test was weak. By calculating Cronbach's alpha coefficient, we estimated the internal consistency or the reliability of each component. The Cronbach's alpha coefficients were above 0.70. This instrument can be used for large-scale population based studies in Turkey.

Abstract
OBJECTIVE We describe the design and report the first results of the Progression of Gastroesophageal Reflux Disease (ProGERD) study, to our knowledge the largest prospective study of GERD patients. STUDY DESIGN AND SETTING Patients were recruited at 1,253 centers in Germany, Austria, and Switzerland. Following an assessment of medical history, all patients were endoscoped and received esomeprazole for 2 to 8 weeks before entering the 5-year observational phase. RESULTS A total of 6,215 patients (53% male, age 54+/-14) were included. Of these patients, 46% reported at least daily symptoms, 15% were unable to work at least once during the prior year, and 71% had visited a physician due to reflux symptoms. Barrett's esophagus (BE) was found in 11% of our GERD patients. In polychotomous regression analysis, the main factors related to the occurrence of the three GERD subgroups (nonerosive, erosive disease, and BE) were age, gender, duration of GERD, body mass index (BMI), smoking, and previous PPI use. Factors associated with longer disease duration were increasing age, male gender, BMI, increasing symptom severity, presence of erosive GERD or BE, positive family history, and smoking. CONCLUSION The findings indicate that GERD is a great burden for patients, and has significant socioeconomic implications. The long-term follow-up period with further endoscopic and histologic evaluations, will help further our understanding of the natural course of the disease.

Abstract
BACKGROUND Gastro-oesophageal reflux disease (GERD) is highly prevalent in Western countries. Because the majority of patients do not present with endoscopic abnormalities, the assessment of the symptom severity and quality of life, and their response to treatment, has become increasingly important. Self-assessed symptom questionnaires are now key instruments in clinical trials. AIM To evaluate the validity of available GERD measurement tools. METHODS An ideal GERD symptom assessment instrument, suitable as a primary end-point for clinical trials, should possess the following characteristics: (i) be sensitive in patients with GERD; (ii) cover the frequency and intensity of typical and atypical GERD symptoms; (iii) be multidimensional (cover all symptom dimensions); (iv) have proven psychometric properties (validity, reliability and responsiveness); (v) be practical and economical; (vi) be self-assessed; (vii) use 'word pictures' which are easy to understand for patients; (viii) respond rapidly to changes (responsiveness over short time intervals); (ix) be used daily to assess changes during and after therapy; and (x) be valid in different languages for international use. RESULTS A literature review revealed five scales that met some of the above characteristics, but did not fulfil all criteria. CONCLUSION There is a need for a new evaluative tool for the assessment of GERD symptoms and their response to therapy.

Abstract
BACKGROUND This article presents a brief inventory for the diagnosis and monitoring of GORD symptoms. METHODS The inventory consists of five items pertaining to different aspects of GORD to be graded for frequency on a 5-point Likert scale. It was validated on a consecutive group of GORD patients diagnosed either by endoscopy (n = 25) or by 24-h ambulatory pH monitoring (acid exposure time > or = 5%; n = 233) and control subjects (n = 300). RESULTS Each of the inventory items was significantly associated with GORD (P < 0.001). Factor analysis indicated that all items loaded on a single scale with a high reliability (Cronbach alpha 0.88). Each item was weighted by its respective odds ratio in favour of GORD and a total score for the scale was then calculated as the sum of weighted scores on the five individual items. Receiver-operator (ROC) curve analysis implemented on a random sample comprising 67% of the group indicated that a total weighted score of 31.6 (percentage of the maximal possible weighted score) was 91% sensitive and 92% specific in the diagnosis of GORD. This score was then validated on the rest of the sample, where it correctly classified patients and controls with a sensitivity of 89% and specificity of 94%. The score proved stable on repeated administration in controls and in patients with stable symptoms, and decreased by 66% (P < 0.001) after 1 month of treatment with omeprazole in patients who reported symptom relief. CONCLUSIONS The scale described in this article is a brief, simple and accurate measure, for the diagnosis of GORD as well as for monitoring its symptoms.
