Gastro-esophageal reflux disease is a chronic disease. It develops along life, more likely recurrent, usually by some months after treatment with responses. This disease apperances in every ages, even in children and newborns, but it is more common at the age over 40 years old with the top age from 50 to 70 years old. The prevelence of disease changed from 10% to 36%. Diagnosis and treatment played an important role in preventation of complications. Pain and hemoghlobin are two complications. Causes gastro-esophageal reflux is very complex. Gastro-esophageal reflux disease is caused by many reasons and the other reasons also have different effects in each patient, even in each time on the same patient

OBJECTIVETo explore the prevalence of gastroesophageal reflux disease (GERD) and its symptoms in Haidian district of Beijing, identify its associated risk factors and analyze the relations between GERD and history of other diseases.

METHODS2615 residents of 18-80 years old were selected to participate in the study by multi-stage sampling from Haidian district from June and September in 2008. Questionnaires were distributed to obtain the information on demographic characteristics, diseases history and the reflux disease questionnaire (RDQ).

RESULTSThe prevalence of GERD in the population was 8.4% (220/2615), and the prevalence of heartburn, reflux, both heartburn and reflux were 1.0% (25/2615), 6.2% (163/2615) and 1.2% (32/2615), respectively. Multi-factor analysis showed rural area (OR = 2.237, 95%CI: 1.422 - 3.517), female (OR = 1.456, 95%CI: 1.085 - 1.955), high education (OR = 1.242, 95%CI: 1.001 - 1.542), pressure (OR = 1.277, 95%CI: 1.089 - 1.497), bad emotional status (OR = 1.320, 95%CI: 1.046 - 1.665), and family history of gastrointestinal disorders (OR = 1.594, 95%CI: 1.075 - 2.365) were significantly associated with GERD. Rural area (OR = 2.481, 95%CI: 1.278 - 4.818), female (OR = 1.747, 95%CI: 0.902 - 3.386), drinking (OR = 1.838, 95%CI: 0.916 - 3.690), no exercise (OR = 2.091; 95%CI: 1.131 - 3.867) and bad emotional status (OR = 1.657, 95%CI: 1.123 - 2.446) were significant risk factors for heartburn. Rural area (OR = 2.171, 95%CI: 1.326 - 3.556), female (OR = 1.505, 95%CI: 1.102 - 2.056), high education (OR = 1.347, 95%CI: 1.063 - 1.706), pressure (OR = 1.317, 95%CI: 1.113 - 1.558), bad emotional status (OR = 1.266, 95%CI: 0.992 - 1.616), and family history of gastrointestinal disorders (OR = 1.739, 95%CI: 1.163 - 2.600) were significantly associated with reflux symptom. History of diseases such as inflammatory bowel disease, anxiety, depression, peptic ulcer, gastritis, and renal diseases were found to be significantly related to GERD and its symptoms.

CONCLUSIONThis area has epidemic of GERD, which was related to mental problems and unhealthy life style, and should be paid more attention by conducting effective community-based interventions.

INTRODUCTION: Infant gastroesophageal reflux disease (GERD) is a significant cause of concern to parents. This study seeks to describe GERD prevalence in infants, evaluate possible risk factors and assess common beliefs influencing management of GERD among Asian parents. METHODS: Mother-infant dyads in the Singapore PREconception Study of long-Term maternal and child Outcomes (S-PRESTO) cohort were prospectively followed from preconception to 12 months post-delivery. GERD diagnosis was ascertained through the revised Infant Gastroesophageal Reflux Questionnaire (I-GERQ-R) administered at 4 time points during infancy. Data on parental perceptions and lifestyle modifications were also collected. RESULTS: The prevalence of infant GERD peaked at 26.5% at age 6 weeks, decreasing to 1.1% by 12 months. Infants exclusively breastfed at 3 weeks of life had reduced odds of GERD by 1 year (adjusted odds ratio 0.43, 95% confidence interval 0.19-0.97, P=0.04). Elimination of "cold or heaty food" and "gas producing" vegetables, massaging the infant's abdomen and application of medicated oil to the infant's abdomen were quoted as major lifestyle modifications in response to GERD symptoms. CONCLUSION Prevalence of GERD in infants is highest in the first 3 months of life, and the majority outgrow it by 1 year of age. Infants exclusively breastfed at 3 weeks had reduced odds of GERD. Cultural-based changes such as elimination of "heaty or cold" food influence parental perceptions in GERD, which are unique to the Asian population. Understanding the cultural basis for parental perceptions and health-seeking behaviours is crucial in tailoring patient education appropriately for optimal management of infant GERD.

BACKGROUND/AIMS: Several studies have demonstrated that sleep problems are associated with functional gastrointestinal disorders (FGIDs): irritable bowel syndrome (IBS), functional dyspepsia, etc, but the relationship between excessive daytime sleepiness (EDS) and FGIDs has not been systematically studied in the general population. This study aims to explore the relationship between EDS and specific types of FGIDs and the effect of the number of FGIDs on EDS. METHODS: A sample of 3600 individuals (aged 18–80 years) was selected from 5 regions in China using a randomized, stratified, multi-stage sampling method. EDS was measured by the Epworth Sleepiness Scale, while gastroesophageal reflux disease (GERD) and other FGIDs were assessed by Reflux Disease Questionnaire and the Rome II diagnostic criteria, respectively. RESULTS: The survey was completed by 2906 individuals (response rate: 80.72%), and 644 individuals (22.16%) had EDS. EDS was significantly associated with ulcer-like dyspepsia (OR, 2.50; 95% CI, 1.08–5.79), diarrhea-predominant IBS (OR, 2.00; 95% CI, 1.09–3.66), alternating IBS (OR, 2.32; 95% CI, 1.30–4.13), functional constipation (OR, 1.68; 95% CI, 1.20–2.35), and GERD (OR, 1.72; 95% CI, 1.08–2.72). Risk of EDS increased along with the increasing numbers of FGIDs: with 1 FGID (OR, 1.72; 95% CI, 1.37–2.15); with 2 FGIDs (OR, 2.43; 95% CI, 1.63–3.62); and with 3 or more FGIDs (OR, 3.26; 95% CI, 1.37–7.78). CONCLUSIONS: FGIDs, such as ulcer-like dyspepsia, diarrhea-predominant IBS, alternating IBS, functional constipation, and GERD, were significantly associated with EDS. Those who suffered from more kinds of FGIDs were more susceptible to EDS.

Chronic cough is a significant medical condition with high prevalence and a strong negative impact on the quality of life. Cough hypersensitivity is thought to underlie chronic cough, with several environmental and host factors interacting to cause neuronal sensitization and chronicity. Comorbid conditions affecting cough reflex pathways, such as upper airway diseases, asthma, and gastroesophageal reflux, play important roles in chronic cough. However, their prevalence may vary in patients living in different geographical regions or with different ethnicities. We conducted a literature review to examine common comorbidities in Korean adult patients with chronic cough, their clinical implications, and the issues that still need to be addressed in the development of clinical evidence of chronic cough in Korean adult patients.

Functional dyspepsia (FD) is a common but under-recognized syndrome comprising bothersome recurrent postprandial fullness, early satiety, or epigastric pain/burning. Epidemiologically, there are two clinically distinct FD syndromes (although these often overlap clinically): postprandial distress syndrome (PDS; comprising early satiety or meal-related fullness) and epigastric pain syndrome. Symptoms of gastroesophageal reflux disease overlap with FD more than expected by chance; a subset has pathological acid reflux. The pre-test probability of FD in a patient who presents with classical FD symptoms and no alarm features is high, approximately 0.7. Coexistent heartburn should not lead to the exclusion of FD as a diagnosis. One of the most exciting observations in FD has been the consistent finding of increased duodenal eosinophilia, notably in PDS. Small bowel homing T cells, signaling intestinal inflammation, and increased cytokines have been detected in the circulation, and elevated tumor necrosis factor-α levels have been significantly correlated with increased anxiety. Postinfectious gastroenteritis is a risk factor for FD. Therapeutic options remain limited and provide only symptomatic benefit in most cases. Only one therapy is known to change the natural history of FD–Helicobacter pylori eradication. Treatment of duodenal eosinophilia is under investigation.

The prevalence of gastoesophageal reflux disease (GERD) has been rapidly increased in Korea during last 20 years. However, there has been no systematic review regarding this disease. The aim of this article was to provide a review of available diagnostic modalities for GERD. This review includes proton pump inhibitor (PPI) test, endoscopy, ambulatory pH monitoring, impedance pH monitoring, and esophageal manometry in order to provide a basis for the currently applicable recommendations in the diagnosis of GERD in Korea. With weekly heartburn or acid regurgitation, the prevalence of GERD has been reported as 3.4% to 7.9%, indicating an increase of GERD in Korea. As the prevalence of Barrett's esophagus has been reported to be low, the screening endoscopy for Barrett's esophagus is not recommended. Several recent meta-analyses re-evaluated the value of the PPI test in patients with typical GERD symptoms and non-cardiac chest pain. That is, the PPI test has been proven to be a sensitive tool for diagnosing GERD in patients with non-cardiac chest pain and in some preliminary trials regarding extraesophageal manifestations of GERD. Ambulatory pH monitoring of the esophagus helps to confirm gastroesophageal reflux in patients with persistent symptoms (both typical and atypical) in the absence of esophageal mucosal damage, especially when a trial of acid suppression has failed. Impedance pH test is useful in refractory reflux patients with primary complaints of typical GERD symptoms, but this value has not been proved in patients with non-cardiac chest pain or extraesophageal symptoms. This systematic review is targeted to establish the strategy of GERD diagnosis, which is essential for the current clinical practice.

Patients with dyspepsia/functional dyspepsia (FD) show frequent overlapping of other gastrointestinal (GI) diseases, such as irritable bowel syndrome, and non-GI diseases, in addition to internal subgroup overlapping. These overlap patients have more frequent or more severe symptoms, poorer health-related quality of life and higher somatization scores, and they are more likely to experience anxiety, depression or insomnia compared to non-overlap patients. The higher prevalence of overlap in patients with dyspepsia/FD is not by chance, indicating common pathogeneses, including visceral hypersensitivity, altered GI motility, infection, and stressful early life events. There are few clinical trials targeting overlap in patients with dyspepsia/FD, and no therapeutic strategy has been established. Further studies in this research area are needed. In this review, we describe the epidemiology, pathogenesis and treatment of overlap in patients with dyspepsia/FD.
