Use of Gastroscopy for Otherwise Healthy Patients With Dyspepsia. J Can Assoc Gastroenterol 2021; 5:32-38. [PMID: 35118225 PMCID: PMC8806042 DOI: 10.1093/jcag/gwab017] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2021] [Accepted: 06/09/2021] [Indexed: 12/16/2022] Open
Abstract
Background Choosing Wisely Canada (CWC) recommends not to perform gastroscopy for dyspepsia in otherwise healthy adults less than 55 years of age (2014). The aim of this study was to evaluate the use of gastroscopy in a young, healthy population with uncomplicated dyspepsia. Methods A retrospective review of gastroscopies completed during 3-month periods in 2015, 2016, and 2017 identified all patients undergoing gastroscopy for the primary indication of dyspepsia. Low-risk patients for dyspepsia were defined as adults, aged 18 to 54 years without alarm symptoms, comorbidities and/or abnormal imaging findings or laboratory values. Gastroscopy and pathology reports were reviewed to identify clinically actionable findings. Clinical outcomes were followed to December 31, 2018 including gastroenterology referrals, emergency room visitation and hospitalization. Results Among 1358 patients having a gastroscopy for dyspepsia, 480 (35%) were low-risk patients. Sixteen patients 3.3% (16/480) had a clinically actionable result found on gastroscopy or biopsy. No malignant lesions were detected. Low-risk patients were followed up for an average of 2.75 years, 8% (39/480) visited the emergency department (ED), 1% (3/480) of patients were admitted to hospital and 12% (59/480) of patients were re-referred for a dyspepsia-related concern. Interpretation A high rate of low yield, high cost, invasive endoscopic investigations were performed in this population of otherwise healthy patients under age 55 years. These data suggest limited uptake of current recommendations against the routine use of gastroscopy to investigate dyspepsia.

Abstract
BACKGROUND Symptom resolution is the most common clinical practice during assessment and evaluation of helicobacter pylori infected patients after employing eradication therapy. OBJECTIVE Prediction of eradication of H. pylori with symptom resolution and assess factors affecting symptom resolution. METHOD Facility based follow up study was done on consented H. pylori positive adult patients who received standard triple therapy consisting of a proton pump inhibitor, amoxicillin, and clarithromycin from May 2016 to April 2018 at Bahir Dar city in Ethiopia. Sociodemographic and clinical data was collected before and after eradication therapy by using pre-developed structured questionnaire. Both positive and negative predictive values were calculated. SPSS version 23 was used to conduct bivariate and backward stepwise multivariate logistic regression to analyze data. P-value < 0.05 at 95%CI was considered as significant. RESULT The study involved a total of 421 patients who completed follow up. Patients' mean age and body weight (±SD) were 30.63 (± 10.74) years and 56.71 (± 10.19) kg, respectively. Complete symptom resolution was achieved in 84.3% of the patients and eradication of H. pylori was successful in 90% of patients. Positive predictive value of complete symptom resolution for H. pylori eradication was 98.9% (351/355) and whereas negative predictive value was 57.6%(38/66). Factors associated with complete symptom resolution were regimen completion (AOR: 2.77 95%CI (1.12-6.86), p = 0.028) and no use of traditional homemade supplements prepared from Fenugreek or Flaxseed (AOR: 2.09 95%CI (1.22-3.58), p = 0.007). CONCLUSION Complete symptom resolution is a powerful predictor of success of H. pylori eradication and can be used to assess H. pylori status after eradication therapy. Assessment of complete symptom resolution should consider regimen completion and traditional practice of using homemade supplements prepared from Fenugreek or Flaxseed.

Abstract
BACKGROUND/AIMS The aim of this study was to determine the prevalence of symptoms and diseases of the lower and upper gastrointestinal system (GIS) in a population-based sample. MATERIALS AND METHODS The cross-sectional cohort study was conducted in Cappadocia cohort comprising the Gülşehir and Avanos districts. The "Gastrointestinal Symptom Questionnaire" was applied to persons over the age of 18 years. RESULTS The GI Symptom Questionnaire was applied to 3369 subjects, and height and body weight were measured in 2797 consenting subjects. Of the participants, 61% were female and the mean patient age was 50±15 years. At least one GI symptom was present in 70.6% of the cohort. The most common upper GI symptoms were gastric bloating (31.0%) and heartburn (29.1%). The most common lower GI symptom was abnormal defecation (33.5). The prevalence of upper GIS and lower GIS diseases was 32.7% and 12.9%, respectively, and the prevalence of togetherness of upper and lower GIS diseases was 9.9%. Prevalence of GIS disease was approximately 3 times higher in females (p<0.001). All of the upper and lower GI symptoms and the prevalence of upper GIS disease increased in line with Body mass index (BMI). CONCLUSION This first population-based, cross-sectional cohort study revealed that the prevalence of GIS diseases is critically high for optimal public health. Special attention must be paid to these diseases while planning health policies and reimbursements.

Abstract
OBJECTIVES Digestive diseases account for >100 million ambulatory care visits annually in the U.S. Yet, comparatively less is known about the true burden of gastrointestinal (GI) symptoms in the general U.S. POPULATION The aim of this study was to use data from the "National GI Survey"-a population-based audit of GI symptoms in >71,000 participants-to determine the prevalence and predictors of GI symptoms in community-dwelling Americans. METHODS We conducted the National GI Survey using a mobile app called MyGiHealth, which employs a computer algorithm that systematically collects participants' GI symptoms. We recruited a nationally representative sample of Americans to complete the survey, which guided respondents through National Institutes of Health (NIH) GI Patient Reported Outcome Measurement Information System (PROMIS®) scales along with questions about relevant comorbidities and demographics. We measured the prevalence of GI symptoms in the past week and employed logistic regression to adjust for confounding. RESULTS Overall, 71,812 individuals completed the survey, of which 61% reported having had ≥1 GI symptom in the past week. The most commonly reported symptoms were heartburn/reflux (30.9%), abdominal pain (24.8%), bloating (20.6%), diarrhea (20.2%), and constipation (19.7%). Less common symptoms were nausea/vomiting (9.5%), dysphagia (5.8%), and bowel incontinence (4.8%). Females, non-Hispanic whites, and individuals who were younger, highly educated, and had medical comorbidities were more likely to have symptoms (all adjusted p < 0.05). CONCLUSIONS In this large population-based study that combined digital health technology with NIH PROMIS questionnaires, we found that GI symptoms are highly prevalent, as nearly two thirds of surveyed Americans are burdened by these symptoms.

On-Demand Therapy with Proton Pump Inhibitors for Maintenance Treatment of Nonerosive Reflux Disease or Mild Erosive Esophagitis: A Systematic Review and Meta-Analysis. Gastroenterol Res Pract 2018; 2018:6417526. [PMID: 30158966 PMCID: PMC6109549 DOI: 10.1155/2018/6417526] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2018] [Revised: 06/30/2018] [Accepted: 07/10/2018] [Indexed: 12/14/2022] Open
Abstract
Background Proton pump inhibitors (PPIs) are widely used for the long-term management of gastroesophageal reflux disease (GERD). However, concerns about the cost and/or inconvenience of continuous maintenance PPI treatment have led to the evaluation of various alternative approaches. Aim To assess the effectiveness of on-demand PPI therapy in the maintenance treatment of nonerosive reflux disease (NERD) or mild erosive esophagitis (EE). Methods We searched MEDLINE, EMBASE, Web of Science, and Cochrane Library from inception until October 2, 2017, for randomized controlled trials (RCTs) comparing on-demand PPI versus placebo or daily PPI in the management of NERD or mild EE (Savary-Miller grade 1). Discontinuation of therapy during the trial was used as a surrogate for patient dissatisfaction and failure of symptomatic control. We calculated pooled odds ratios (OR) to evaluate the efficacy of on-demand PPI treatment. Separate analyses were conducted for studies comparing on-demand PPI with daily PPI and with placebo. Subgroup analysis was done based on NERD studies alone and on studies of both NERD and mild EE. These were analyzed using a random effects model. Results We included 10 RCTs with 4574 patients. On-demand PPI was superior to daily PPI (pooled OR = 0.50; 95% confidence interval (CI) = 0.35, 0.72). On subgroup analysis in NERD patients only, pooled OR was 0.44 (0.29, 0.66). In studies including patients with NERD and mild EE, pooled OR was 0.76 (0.36, 1.60). For studies comparing on-demand PPI with placebo, pooled OR was 0.21 (0.15, 0.29); subgroup analyses of studies evaluating NERD only and studies conducted in NERD and mild EE showed similar results (pooled OR was 0.22 (0.13, 0.36) and 0.18 (0.11, 0.31), resp.). Conclusions On-demand PPI treatment is effective for many patients with NERD or mild EE. Although not FDA-approved, it may be adequate for those patients whose symptoms are controlled to their satisfaction.

Abstract
OBJECTIVE Transoral incisionless fundoplication (TIF) is a completely endoscopic approach to treat gastroesophageal reflux disease (GERD). We previously reported our initial results demonstrating safety and early effectiveness. We now present an updated experience describing outcomes with longer follow-up. METHODS For a three-year period, TIF procedures were performed on 80 patients. Preoperative workup routinely consisted of contrast esophagram and manometry. PH testing was reserved for patients with either atypical symptoms or typical symptoms unresponsive to proton-pump inhibitors (PPIs). Heartburn severity was longitudinally assessed using the GERD health-related quality of life index. Safety analysis was performed on all 80 patients, and an effectiveness analysis was performed on patients with at least 6-month follow-up. RESULTS Mean procedure time was 75 minutes. There were seven (8.75%) grade 2 complications and one (1.25%) grade 3 complication (aspiration pneumonia). The median length of stay was 1 day (mean, 1.4). Forty-one patients had a minimum of 6-month of follow-up (mean, 24 months; range, 6-68 months). The mean satisfaction scores at follow-up improved significantly from baseline (P < 0.001). Sixty-three percent of patients had completely stopped or reduced their PPI dose. Results were not impacted by impaired motility; however, the presence of a small hiatal hernia or a Hill grade 2/4 valve was associated with reduced GERD health-related quality of life scores postoperatively. CONCLUSIONS At a mean follow-up of 24 months, TIF is effective. Although symptoms and satisfaction improved significantly, many patients continued to take PPIs. Future studies should focus on longer-term durability and comparisons with laparoscopic techniques.

Abstract
BACKGROUND Functional dyspepsia (FD) is a highly prevalent functional bowel disorder. The effects of antidepressant therapy (ADTx) on gastric sensorimotor function in FD patients are poorly understood. AIMS Determine whether FD and subtypes with abnormalities in gastric function respond differently to ADTx compared to those with normal physiology. METHODS This multicenter, prospective trial randomized FD patients to 12 weeks of amitriptyline (AMI; 50 mg), escitalopram (ESC; 10 mg), or matching placebo. Demographics, symptoms, psychological distress, gastric emptying, and satiation were measured. Gastric accommodation (GA) using single-photon emission computed tomography imaging was performed in a subset of patients. An intent to treat analysis included all randomized subjects. The effect of treatment on gastric emptying was assessed using ANCOVA. A post hoc appraisal of the data was performed categorizing patients according to the Rome III subgrouping (PDS and EPS). RESULTS In total, 292 subjects were randomized; mean age=44 yrs. 21% had delayed gastric emptying. Neither antidepressant altered gastric emptying, even in those with baseline delayed gastric emptying. GA increased with ADTx (P=0.02). Neither antidepressant affected the maximal-tolerated volume (MTV) of the nutrient drink test although aggregate symptom scores improved compared to placebo (P=0.04). Patients with the combined EPS-PDS subtype (48%) had a lower MTV on the nutrient drink test compared to the EPS group at baseline (P=0.02). Postprandial bloating improved with both AMI (P=0.03) and ESC (P=0.02). CONCLUSIONS Amitriptyline (50 mg) improves FD symptoms but does not delay gastric emptying, even in patients with baseline delayed gastric emptying. GA improved with low-dose ADTx; the precise mechanism of action is unknown warranting further study.

Abstract
The purpose of this methodological study is to investigate the validity and reliability of the Turkish version of the Gastrointestinal Symptom Rating Scale (GSRS). The scale was adapted to the Turkish language via backward translation. Content validity was examined by referring to experts. Reliability was examined via test-retest reliability and internal consistency, and validity was examined with divergent and convergent validity. The Epworth Sleepiness Scale (ESS) and the Marlowe-Crowne Social Desirability Scale (MCSDS) were used for divergent validity. As for convergent validity, the Constipation Severity Instrument (CSI) and the Patient Assessment of Constipation Quality of Life Scale (PAC-QOLQ) were utilized. The relationship between the GSRS and the health-related quality of life (36-item short-form health survey [SF-36]) was also analyzed. The study population consisted of patients in orthopedic clinic who volunteered to participate. Test-retest reliability was examined with the participation of 30 patients; internal consistency and validity were examined with 150 patients. Test-retest reliability correlation coefficients of the GSRS varied from 0.39 to 0.87 for all items. For internal consistency, the GSRS's item total correlation was found to be 0.17-0.67, and Cronbach α was 0.82 for all items. There was a positive linear significant correlation between the GSRS, CSI, and PAC-QOLQ. There was no significant correlation between the GSRS, MCSDS, and ESS. Higher GSRS scores inversely correlated with general quality of life (SF-36). The Turkish version of the GSRS has been found to be a reliable and valid instrument for assessing patients' gastrointestinal symptoms. Therefore, this instrument can be confidently used with Turkish individuals.

Abstract
Cystic fibrosis (CF) is associated with different gastrointestinal motility disturbances and syndromes. We aim to assess gastric emptying in patients with CF compared to healthy controls by a systematic review of existing literature. Medical databases and abstracts from major gastroenterology and CF meetings were reviewed. Emptying times in CF patients were compared with healthy controls using random effects models. Subgroup analysis stratified results by age and diagnostic modality. Nineteen studies from 7 countries included 574 subjects (359 CF patients and 215 controls). Using pooled analysis frequency of gastroparesis was high (38%, 95% CI 30-45%) but results were highly dependent on the diagnostic modality. Delayed gastric emptying is more common in CF compared to general population. Scintigraphy identified rapid gastric emptying in a subgroup of CF patients, but this finding disappeared with adequate pancreatic enzyme replacement and after other diagnostic modalities were included.

Abstract
OBJECTIVES To develop and validate a gastrointestinal (GI) symptom rating questionnaire for patients with luminal GI symptoms including where no diagnosis has been made. STUDY DESIGN AND SETTING We developed and validated the Gastrointestinal Symptom Rating Questionnaire (GSRQ) in three stages: (1) item generation to identify the relevant items for scale inclusion; (2) development and piloting on patients with a known GI disorder; and (3) testing in a sample of trial patients. We examined the underlying dimensions of the scale, internal consistency, validity, reproducibility, and responsiveness. RESULTS We identified four interpretable factors on the GSRQ. The GSRQ had good internal consistency (corrected item-subscale correlations between 0.4 and 0.8) and Cronbach's alpha greater than 0.7 for each subscale. Construct validity was demonstrated by modest but significant correlations with the Short Form 36 and the EQ5D index value. We demonstrated good reproducibility with intraclass correlations for test-retest scores between 0.71 and 0.77, and significant responsiveness ratios for all subscales in patients who had improved, and in two of the subscales in patients who had deteriorated. CONCLUSION The GSRQ could be a useful tool to monitor quality of life in various luminal GI conditions and where a formal diagnosis has not been made.

AIM: To determine the prevalences of symptoms consistent with gastroesophageal reflux disease (GERD) and dyspepsia in South America.
METHODS: A telephone survey was conducted among adult owners of land-based telephones in São Paulo, Brazil, using previously validated computer-assisted sampling and survey protocols. The Portuguese-language survey included (1) sociodemographic characteristics (e.g., weight, height, smoking) and comorbidities; (2) dietary habits; (3) presence of symptoms consistent with GERD or dyspepsia within the prior 3 mo; and (4) use of medications and other therapies to manage symptoms. Data were stratified post-hoc into three homogeneous geographical regions of São Paulo according to the Social Exclusion Indices of the districts and postal codes. Survey response data from each respondent were weighted by the numbers of adults and landline telephones in each household. The analyses were weighted to account for sampling design and to be representative of the São Paulo population according to city census data.
RESULTS: Among 4570 households contacted, an adult from 3050 (66.7%) agreed to participate. The nonresponse rate was 33.3%. The mean (SE) respondent age was 42.6 (16.0) years. More than half of all respondents were women (53.1%), aged 18 through 49 years (66.7%), married or cohabitating (52.5%), and/or above normal-weight standards (i.e., 35.3% overweight and 16.3% obese). A total of 26.5% of women were perimenopausal. More than 20% of respondents reported highly frequent symptoms consistent with GERD (e.g., gastric burning sensation = 20.8%) or dyspepsia (e.g., abdominal swelling/distension = 20.9%) at least once per month. Prevalences of these symptoms were significantly (approximately 1.5- to 2.0-fold) higher among women than men but did not vary significantly as a function of advancing age. For instance, 14.1% of women reported that they experienced stomach burning (symptom of GERD) at least twice per week, compared to 8.4% of men (P = 0.012 by χ2 test). A total of 15.7% of women reported that they experienced abdominal swelling (symptom of dyspepsia) at least twice per week, compared to 6.4% of men (P < 0.001 by χ2 test). Despite frequent manifestations of GERD or dyspepsia, most (≥ 90%) respondents reported that they neither received prescription medications from physicians, nor took behavioral measures (e.g., dietary modifications), to manage symptoms.
CONCLUSION: Symptoms consistent with dyspepsia and GERD are prevalent in Brazil and represent major public-health and clinical challenges.

Abstract
BACKGROUND Prior estimates suggest that up to 40% of the US general population (GP) report symptoms of gastroesophageal reflux disease (GERD). However, symptoms in the GP versus patients seeking care for gastrointestinal (GI) complaints have not been compared. We estimated the prevalence and severity of GERD symptoms in the GP versus GI patients, and identified predictors of GERD severity. We hypothesized that similar to functional GI disorders, psychosocial factors would predict symptom severity in GERD as much, or perhaps more, than care-seeking behavior alone. METHODS We compared the prevalence of heartburn and regurgitation between a sample from the US GP and patients seeking GI specialty care. We compared GERD severity between groups using the NIH PROMIS(®) GERD scale. We then performed multivariable regression to identify predictors of GERD severity. RESULTS There was no difference in the prevalence of heartburn between the GP and patient groups (59 vs. 59%), but regurgitation was more common in patients versus GP (46 vs. 39%; p = 0.004). In multivariable regression, having high visceral anxiety (p < 0.001) and being divorced or separated (p = 0.006) were associated with higher GERD severity. CONCLUSIONS More than half of a GP sample reports heartburn-higher than previous series and no different from GI patients. Although regurgitation was more prevalent in patients versus the GP, there was no difference in GERD severity between groups after adjusting for other factors; care seeking in GERD appears related to factors beyond symptoms, including visceral anxiety.

Abstract
Background It is suggested that symptoms related to gastroparesis are more common in female than in male patients with type 2 diabetes mellitus (T2DM). The association between sex and prevalence of symptoms suggestive of gastroparesis among patients with T2DM in Israel has not been reported. The aim of this study was to describe the associations between sex, clinical characteristics, type, severity and prevalence of dyspeptic symptoms in a large population of patients with T2DM in Israel. Methods All patients completed a demographic questionnaire and the Gastroparesis Cardinal Symptom Index (GCSI). Data regarding disease duration, medications, complications, recent blood glucose and HbA1c levels were also collected. In this nested case–control study, 173 female and 209 male patients were identified from within a cross-sectional survey of 382 patients with T2DM. Logistic and general linear modeling was used to assess associations between sex, clinical data, and the presence (type and number) of symptoms. Results Compared to males, female patients with T2DM had a higher body mass index (BMI) (31.9 vs. 29.2; P = 0.001) and HbA1c levels (7.9 vs. 7.5; P = 0.04). A larger proportion of males suffered from peripheral vascular disease (P = 0.02) and ischemic heart disease (P = 0.001). Other disease characteristics did not differ between the sexes. The prevalence of nausea (P = 0.001), early satiety (P = 0.005), loss of appetite (P = 0.002), or presence of any cardinal symptom (P = 0.001) was significantly higher among females. Severity of most cardinal symptoms was also higher in females. The presence of at least one cardinal symptom was more likely among obese females with longer disease duration and poor glycemic control. Conclusions Prevalence and severity of symptoms suggestive of gastroparesis is particularly high among obese females with long standing and poorly controlled T2DM.

Abstract
Gastrointestinal symptoms have a major impact on the quality of life and are becoming more prevalent in the western population. The enteric nervous system (ENS) is pivotal in regulating gastrointestinal functions. Purinergic neurotransmission conveys a range of short and long-term cellular effects. This study investigated the role of the ADP-sensitive P2Y13 receptor in lipid-induced enteric neuropathy. Littermate P2Y13 (+/+) and P2Y13 (-/-) mice were fed with either a normal diet (ND) or high-fat diet (HFD) for 6 months. The intestines were analysed for morphological changes as well as neuronal numbers and relative numbers of vasoactive intestinal peptide (VIP)- and neuronal nitric oxide synthase (nNOS)-containing neurons. Primary cultures of myenteric neurons from the small intestine of P2Y13 (+/+) or P2Y13 (-/-) mice were exposed to palmitic acid (PA), the P2Y13 receptor agonist 2meSADP and the antagonist MRS2211. Neuronal survival and relative number of VIP-containing neurons were analysed. In P2Y13 (+/+), but not in P2Y13 (-/-) mice, HFD caused a significant loss of myenteric neurons in both ileum and colon. In colon, the relative numbers of VIP-containing submucous neurons were significantly lower in the P2Y13 (-/-) mice compared with P2Y13 (+/+) mice. The relative numbers of nNOS-containing submucous colonic neurons increased in P2Y13 (+/+) HFD mice. HFD also caused ileal mucosal thinning in P2Y13 (+/+) and P2Y13 (-/-) mice, compared to ND fed mice. In vitro PA exposure caused loss of myenteric neurons from P2Y13 (+/+) mice while neurons from P2Y13 (-/-) mice were unaffected. Presence of MRS2211 prevented PA-induced neuronal loss in cultures from P2Y13 (+/+) mice. 2meSADP caused no change in survival of cultured neurons. P2Y13 receptor activation is of crucial importance in mediating the HFD- and PA-induced myenteric neuronal loss in mice. In addition, the results indicate a constitutive activation of enteric neuronal apoptosis by way of P2Y13 receptor stimulation.

Abstract
AIMS To estimate the prevalence of symptoms suggestive of gastroparesis and their association to clinical and demographic data in a large population of patients with diabetes mellitus and in the general population in Israel. METHODS A cross-sectional survey of type 2 diabetic patients treated in community settings was performed. All patients and controls completed a demographic questionnaire as well as the Gastroparesis Cardinal Symptom Index (GCSI). Data regarding disease duration, medications, complications, recent blood glucose and HbA1C levels, were also collected. RESULTS A total of 382 patients and 88 healthy volunteers were included. Patients and controls were aged 63.07 ± 10.63 and 58.69 ± 10.73 years respectively with a BMI of 30.45 ± 8.15 and 25.64 ± 4.25 kg/m(2) respectively. Compared to controls, more patients with diabetes complained of nausea (24.8% vs. 4.5%, p < 0.0001), post-prandial fullness (44.6% vs. 26.1%, p = 0.001), bloating (48.8% vs. 36.4%, p = 0.035) and stomach or belly visibly larger after a meal (53% vs. 29.5%, p < 0.0001). In multivariate analysis, symptoms were associated with female sex, BMI, blood glucose, HbA1C, metformin treatment and disease duration. CONCLUSIONS The prevalence of symptoms suggestive of gastroparesis among patients with diabetes mellitus in Israel is high and is independently associated with female sex and metformin therapy.

Abstract
BACKGROUND Although highly prevalent, little is known about the economic impact of functional dyspepsia (FD). AIMS To quantify FD patients' health care utilisation patterns and to estimate direct and indirect costs of FD to patients. METHODS ICD-9 codes identified adult patients with dyspepsia. A validated questionnaire was mailed to patients who met Rome III criteria for FD. RESULTS Three hundred and fifty-five patients met all inclusion criteria. The response rate was 63%. The respondents' mean age was 50 (14) years; 75% were women; 52% of respondents rated their FD as moderate. Patients reported 3 visits (mean) to their PCP over 12 months; 75% reported having blood work, 92% an EGD, 59% an ultrasound and 40% a CT scan. The direct cost of testing using Medicare reimbursement rates per patient was $582. To treat FD symptoms, 89% tried dietary changes, 89% over-the-counter medications, 87% prescription medications and 25% alternative therapies. Mean patient expenditure over the last year was $246 for OTC medications (range $0-12,000), $290 for co-payments (range $0-9,000) and $110 for alternative treatments (range $0-3,741). Total mean direct cost yearly to patients was $699. In the 7 days prior to completing the questionnaire, respondents reported a mean of 1.4 h absence from work. Extrapolating the results to the US population, we conservatively calculate the costs of FD were $18.4 billion in 2009. CONCLUSIONS Functional dyspepsia patients incur significant direct and indirect costs and work productivity is impaired by dyspeptic symptoms.

Abstract
BACKGROUND The purpose of this study was to assess differences in health care resource utilization and costs associated with once-daily and twice-daily proton pump inhibitor (PPI) therapy. Most patients with gastroesophageal reflux disease (GERD) achieve symptom control on once-daily PPI therapy, but approximately 20%-30% require twice-daily dosing. METHODS Patients were ≥18 years of age with at least one medical claim for GERD and at least two PPI claims from HealthCore's Integrated Research Database (HIRD(SM)) during 2004-2009. Patients were continuously eligible for 12 months before and after the index date (date of first PPI claim). Based on PPI dosing throughout the post-index period (quantity of medication dispensed/number of days supply), patients were classified as once-daily (dose ≤ 1.5 pills per day) or twice-daily (≥1.5) PPI users. RESULTS The study cohort included 248,386 patients with GERD (mean age 52.8 ± 13.93 years, 56% females) of whom 90% were once-daily and 10% were twice-daily PPI users. The Deyo-Charlson Comorbidity Index for once-daily and twice-daily PPI users was 0.70 ± 1.37 and 0.89 ± 1.54, respectively (P < 0.05). More once-daily patients had claims for Barrett's esophagus (5% versus 2%, P < 0.0001) than twice-daily patients. Post-index, higher proportions of twice-daily patients had at least one GERD-related inpatient visit (7% versus 5%), outpatient visit (60% versus 49%), and office visit (48% versus 38%) versus once-daily patients (P < 0.0001). Mean total GERD-related health care costs were $2065 ± $6636 versus $3749 ± $11,081 for once-daily and twice-daily PPI users, respectively (P < 0.0001). CONCLUSION Patients receiving twice-daily PPI therapy were likely to have more comorbid conditions and greater health care utilization and overall costs compared with patients using once-daily PPI therapy.

Abstract
BACKGROUND Gastroparesis (GP) is characterized by delayed gastric emptying in the absence of mechanical outlet obstruction. Symptoms may include nausea, vomiting, bloating, early satiety, abdominal pain, and weight loss. Delayed gastric emptying of a solid-phase meal assessed by radionuclear scintigraphy is the criterion standard for diagnosis. The prevalence of GP is difficult to estimate due to the lack of a validated, widely available diagnostic test that can be applied in primary care. The extent of this problem in children is unknown. METHODS We studied a cohort of children with GP diagnosed by radionuclear scintigraphy to identify demographics, symptoms, comorbidities, treatment, and outcomes. A retrospective analysis of 239 patients between ages 0 and 21 years was performed. RESULTS The mean age of presentation was 7.9 years, and boys and girls were almost equally affected, that is, 48.5% and 51.5%, respectively. Vomiting was the most frequent presenting symptom (68%), followed by abdominal pain (51%), nausea (28%), weight loss (27%), early satiety (25%), and bloating (7%). Almost 75% of patients responded to intravenous erythromycin administered provocatively during gastric scintigraphy. In a majority of the patients, no cause was identified, that is, idiopathic GP (70%), followed by drugs (18%) and postsurgical (12.5%) causes. Only 4% patients had diabetic GP, and our population was essentially narcotic naïve (2%). After an average of 24 months' follow-up, the most common complication was esophageal reflux (67%). Despite different therapeutic modalities, by the end of the follow-up period, a significant improvement in symptoms was reported by an average of 60%, regardless of sex, age, or degree of emptying delay. CONCLUSIONS GP has a good prognosis in childhood despite different etiologies, symptom presentation, and therapy.

Abstract
BACKGROUND Peptic ulcer disease is a multifactorial health problem affecting almost all populations worldwide. Large scale population-based studies are crucial to understanding its scope and specifications in various nations. We aimed to explore environmental risk factors of peptic ulcer disease in the first population based study in Ardabil, Northwest Iran. METHODS This study was a part of a larger survey on upper gastrointestinal tract health conducted in Ardabil and Meshkinshahr with a total catchment area population of 600,000 persons during 2000-01. Using a random sampling proportional to place of residence, 1122 persons aged 40 or elder were selected. 1011 (90.1%) accepted participation and underwent a comprehensive medical examination and a systematic upper gastrointestinal endoscopy. Point prevalence of peptic ulcers was correlated to various life style risk factors. RESULTS
Gastric and duodenal ulcers were identified in 33 (3.26%) and 50 (4.94%) participants, making an overall prevalence of 8.20%. Based on multivariable logistic regression analyses, H.pylori infection (OR 3.1, 95% CI: 2.1-4.7), Smoking (OR 1.8, 95% CI: 1.1-6.8), and chronic intake of NSAIDs (OR 2.8, 95% CI: 1.3-4.4) were main risk factors of gastric ulcer. For duodenal ulcer, in addition to H.pylori infection (OR 5.6, 95% CI: 1.9-8.8) and Smoking (OR 2.3, 95% CI: 1.4-6.5), male gender (OR 3.6, 95% CI: 1.2-5.8) and living in an urban area (OR 1.9, 95% CI: 1.1-5.2) were among significant risk factors.
CONCLUSION This is the first population-based endoscopic study in North West of Iran reporting accurate point prevalence of peptic ulcer disease. The rate of 3.3% for gastric ulcer and 4.9% for duodenal ulcers are substantially lower than the estimates reported in Asian population-based endoscopic studies but higher than European reports.

Abstract
Although gastresophageal reflux disease (GERD) is highly prevalent in Western countries, we have very little data about it in African countries. The aim of the study is to determine the prevalence and severity of GERD symptoms among Tunisian subjects and report its characteristics, consultation rate, management modes, as well as patients' satisfaction. Five hundred subjects living in Tunisia were interviewed face to face. The study was conducted at seven centers of primary care at Monastir's department by six interviewer doctors. The questionnaire consisted of 30 questions relating to subject attributes, lifestyle factors, medical history, reflux-related symptom characteristics, consultation behavior, previous treatments for GERD, and description of the last episode. Symptoms were defined as 'frequent' if they occurred at least weekly and 'occasional' if they occurred less frequently during the last year. The mean age was 42.3 ± 17.3 years and 75.6% were females. Over the previous year, 60% of the respondents reported suffering any GERD symptom. The prevalence of frequent GERD is 24%. Female gender (odds ratio [OR]: 1.97[1.15-3.37]) and body mass index ≥ 25 (OR: 1.54[1.042-2.29]) were associated with increased risk of GERD symptom. Only 22.3%, sought medical advice about GERD symptoms in the last year. In the univariate and multivariate analysis, work status, frequency and intensity of symptoms, duration of symptom, and association of atypical symptoms were associated with a higher frequency of medical consultation for GERD symptoms. Among the subjects complaining about heartburn, 34% took medications. GERD symptoms are common among Tunisian subjects. Few heartburn sufferers seek medical attention, and most do not take medications for symptomatic control.

Abstract
BACKGROUND Associated with neuropathy, symptoms suggestive of gastroparesis are common in patients with type 2 diabetes mellitus (T2DM) and include nausea, vomiting, bloating and early satiety. Gastric motor abnormalities have been reported in obese patients, and obesity is associated with T2DM. An association between obesity and gastroparesis symptoms in diabetic patients with neuropathy has not been investigated. METHODS In this nested case-control study, 161 patients with neuropathy were identified from within a cross-sectional survey of 380 T2DM patients. Of these, 134 (83.2%, "cases") had at least one cardinal symptom suggestive of gastroparesis. The remaining symptom-free subjects served as controls. Logistic and general linear modeling was used to assess associations between obesity and the presence and number of symptoms. RESULTS Subjects were 66.6±10 years of age. Cases were significantly more likely than controls to be obese (89% vs. 77%, P=.04), female (55.6% vs. 33.3%) and hypertensive (90.2% vs. 63%, P=.001) and to report adherence to diet (87.4% vs. 66.7%, P=.007). In a logistic regression model including sex, hypertension, antiaggregant therapy, adherence to diet therapy and an obesity-by-sex interaction term, obesity emerged as a significant independent predictor of any cardinal symptom suggestive of gastroparesis (odds ratio 9.86, 95% confidence interval 1.4-69.2, P=.02). Obesity was also identified as a significant independent predictor of number of cardinal symptoms suggestive of gastroparesis in the general linear model. Obese subjects reported significantly more early satiety (61.5% vs. 35.2%, P=.001), fullness (63.7% vs. 40.8%, P=.004), bloating (70.3% vs. 49.3%, P=.006) and abdominal distention (71.4 vs. 50.7%, P=.007) than nonobese subjects. Further, obese subjects reported more cardinal symptoms suggestive of gastroparesis symptoms (4.2±2.4 vs. 3.1±2.5, P=.01). CONCLUSIONS Obesity emerged as a significant independent predictor of cardinal symptoms suggestive of gastroparesis in patients with T2DM and neuropathy. This finding suggests that mechanisms in addition to neuropathy play a role in the generation of symptoms suggestive of gastroparesis in this patient population.

Abstract
Gastroesophageal reflux disease (GORD) is increasing in prevalence and is highly associated with several lung diseases such as asthma and COPD. Current diagnostic methods are imperfect, being insensitive, non-specific, expensive, or invasive. An accurate diagnosis of GORD can aid effective treatment and have significant clinical impact. Novel methods such as exhaled breath condensate analysis and electronic nose technology have the potential to improve the accuracy of diagnosing GORD.

Abstract
Until recently catheter-based 24-h pH monitoring has been the primary methodology for the objective diagnosis of gastroesophageal reflux disease. Yet, this system has some drawbacks, such as patient discomfort, marginal sensitivity, and the inability to detect nonacid reflux. Hampered by these limitations, several new techniques have been recently introduced in clinical practice. In particular, wireless capsule pH monitoring and multichannel intraluminal impedance-pH testing have been forwarded as more sophisticated means of enhancing patient comfort during testing as well as our ability to diagnose gastroesophageal reflux disease, especially in those patients who complain of symptoms of gastroesophageal reflux disease despite adequate acid suppression therapy. The goal of this review is to compare the clinical applicability, advantages and drawbacks of catheter-based 24-h pH testing, wireless capsule pH monitoring, and multichannel intraluminal impedance-pH.

Abstract
AIM: To study the natural history and prevalence of heartburn at a 10-year interval, and to study the effect of heartburn on various symptoms and activities.
METHODS: A population-based postal study was carried out. Questionnaires were mailed to the same age- and gender-stratified random sample of the Icelandic population (aged 18-75 years) in 1996 and again in 2006. Subjects were classified with heartburn if they reported heartburn in the preceding year and/or week, based on the definition of heartburn.
RESULTS: Heartburn in the preceding year was reported in 42.8% (1996) and 44.2% (2006) of subjects, with a strong relationship between those who experienced heartburn in both years. Heartburn in the preceding week was diagnosed in 20.8%. There was a significant relationship between heartburn, dyspepsia and irritable bowel syndrome. Individuals with a body mass index (BMI) below or higher than normal weight were more likely to have heartburn. Heartburn caused by food or beverages was reported very often by 20.0% of subjects.
CONCLUSION: Heartburn is a common and chronic condition. Subjects with a BMI below or higher than normal weight are more likely to experience heartburn. Heartburn has a great impact on daily activities, sleep and quality of life.

Abstract
The study aims to determine if differences exist among racial/ethnic groups in the prevalence of gastroesophageal reflux symptoms in adolescents. A cross-sectional questionnaire was administered to a sample of students in four racially and ethnically diverse high schools in suburban Chicago. A total of 2561 questionnaires were analyzed: 33% Hispanics, 30% Caucasians, 22% African Americans, 15% Asians, 54% female, mean age 15.8 (±1.3) years. Thirty-two percent had at least one esophageal and/or respiratory symptom ≥once a week. Caucasians and African Americans had more dysphagia than Hispanics and Asians (7% vs. 4%; P= 0.04). Hispanics had more heartburn (13% vs. 9-11%; P= 0.06) but this was not statistically significant. There was no difference for regurgitation. Hispanic females had more dysphagia (6% vs. 3%; P= 0.02) and heartburn (17% vs. 9%; P= 0.0003) than Hispanic males. African Americans and Caucasians had more respiratory symptoms than Hispanics and Asians (29%, 24% vs. 18%; P= 0.000004). Students with esophageal symptoms were more likely to have respiratory symptoms (46% vs. 17%; P < 0.0005). African Americans and Caucasians with esophageal symptoms had more respiratory symptoms than Hispanics and Asians with esophageal symptoms (55%, 49% vs. 42%, 34%; P= 0.0003). Asians and Hispanics were less likely to treat symptoms than African Americans and Caucasians (26%, 33% vs. 47%, 49%; P= 0.001). We found that differences exist among the racial/ethnic groups with esophageal and respiratory symptoms; esophageal symptoms are a risk factor for respiratory symptoms, and Asians and Hispanics seek less medical help. Future research should focus on whether the differences found continue and reasons for them.

Abstract
BACKGROUND Gastroesophageal reflux disease imposes a significant burden of illness in Western populations. However, data on the impact of reflux symptoms on daily life in Asian populations are scarce. The current study aimed to evaluate the impact of GERD (defined on the basis of symptoms) on health-related quality-of-life (HRQoL) in individuals from five regions in China, as part of the Systematic Investigation of Gastrointestinal Diseases in China (SILC) study. METHODS In total, 18 000 residents were randomly selected from across five regions of China and asked to complete a general information questionnaire and a Chinese version of the Reflux Disease Questionnaire (RDQ). A randomly selected subsample of one-fifth of subjects (20% from each region) completed Chinese versions of the 36-item self-administered (SF-36) questionnaire and Epworth Sleepiness Scale (ESS) questionnaire. Reflux symptoms were defined as the presence of heartburn and/or regurgitation. Symptom-defined GERD was diagnosed as mild heartburn and/or regurgitation ≥2 days per week, or moderate/severe heartburn and/or regurgitation ≥1 day a week, based on the Montreal Definition of GERD for population-based studies. RESULTS The response rate was 89.4% for the total sample (16 091/18 000), and for the 20% subsample (3219/3600). Meaningful impairment was observed in all 8 SF-36 dimensions in participants with symptom-defined GERD, in 7 of the 8 SF-36 dimensions in participants with troublesome reflux symptoms, and in 6 of the 8 SF-36 dimensions in participants with reflux symptoms below the threshold for symptom-defined GERD. Meaningful daytime sleepiness was also observed in each of these groups. The proportion of individuals reporting troublesome symptoms increased as reflux symptom frequency and severity approached the threshold for symptom-defined GERD, and this was associated with concomitant decreases in all HRQoL measures. Troublesome symptoms were reported by 68.2% (75/110) of individuals with symptom-defined GERD. CONCLUSIONS GERD diagnosed using symptom/frequency criteria (recommended for population-based studies), or based on troublesome reflux symptoms (recommended for the clinic), is associated with significantly impaired HRQoL in Chinese individuals. However, patient groups identified using these definitions do not overlap completely, suggesting that they capture slightly different, though clinically relevant, GERD populations.

Abstract
Background/Aims Current therapy for gastroparesis with prokinetic agents is limited by options and side effects. One macrolide, erythromycin (ERY), is associated with possible sudden cardiac death from QT prolongation due to P450 iso-enzyme inhibition. An alternative, azithromycin (AZI), lacks P450 inhibition. We compared the effect on gastric emptying half-times (t½) between AZI and ERY in patients diagnosed with gastroparesis by gastric emptying scintigraphy. Methods Patients stopped medications known to affect gastric emptying prior to the study, and then ingested 1 scrambled egg meal labeled with 18.5-37 MBq of technetium-99m sulfur colloid followed by continuous imaging for 120 minutes, at 1 minute per frame. A simple linear fit was applied to the rate of gastric emptying, and gastric emptying t½ was calculated (normal = 45-90 minutes). At 75-80 minutes, if the stomach had clearly not emptied, patients were given either ERY (n = 60) or AZI (n = 60) 250 mg IV and a new post-treatment gastric emptying t½ was calculated. Results Comparison of gastric emptying t½ showed a similar positive effect (mean gastric emptying t½ for AZI = 10.4 ± 7.2 minutes; mean gastric emptying t½ for ERY = 11.9 ± 8.4 minutes; p = 0.30). Conclusions AZI is equivalent to ERY in accelerating the gastric emptying of adult patients with gastroparesis. Given the longer duration of action, better side effect profile and lack of P450 interaction for AZI as compared with ERY, further research should evaluate the long term effectiveness and safety of AZI as a gastroparesis treatment.

Abstract
BACKGROUND & AIMS Functional dyspepsia (FD) is a common morbid condition but data are limited on the direct and indirect costs for employees with FD or on its impact on productivity. Few data on absenteeism and no objective information are available. This study aimed to assess the impact of FD on costs and effects on absenteeism and work output (productivity). METHODS We performed a retrospective analysis of payroll data and adjudicated health insurance medical and prescription claims collected over a 4-year study period (January 1, 2001 to December 31, 2004) from more than 300,000 employees. Data from employees with and without (controls) FD were compared using 2-part regression techniques. Outcome measures included medical (total and by place of service) and prescription costs, absenteeism, and objectively measured productivity output. RESULTS Employees with FD (N = 1669) had greater average annual medical and prescription drug costs and indirect costs (owing to sick leave and short- and long-term disability absences) than controls (N = 274,206). Compared with controls, the FD employees incurred costs that were $5138 greater and had greater costs for each place of service (all P < .0001). The employees with FD had an additional 0.83 absence days per year and produced 12% fewer units per hour than controls (both P < .05). CONCLUSIONS Employees with FD have greater costs at all places of service and lower productivity than employees without FD.

Abstract
Gastroesophageal reflux (GER) frequently triggers or worsens cardiac pain or symptoms in patients with coronary heart disease. This study aimed to determine whether GER enhances the activity of upper thoracic spinal neurons receiving noxious cardiac input. Gastric fundus and pyloric ligations as well as a longitudinal myelotomy at the gastroesophageal junction induced acute GER in pentobarbital-anesthetized, paralyzed, and ventilated male Sprague-Dawley rats. Manual manipulations of the stomach and lower esophagus were used as surgical controls in another group. At 4-9 h after GER surgery, extracellular potentials of single neurons were recorded from the T3 spinal segment. Intrapericardial bradykinin (IB) (10 microg/ml, 0.2 ml, 1 min) injections were used to activate cardiac nociceptors, and esophageal distensions were used to activate esophageal afferent fibers. Significantly more spinal neurons in the GER group responded to IB compared with the control group (69.1 vs. 38%, P < 0.01). The proportion of IB-responsive neurons in the superficial laminae of GER animals was significantly different from those in deeper layers (1/8 vs. 46/60, P < 0.01); no difference was found in control animals (7/25 vs. 20/46, P > 0.05). Excitatory responses of spinal neurons to IB in the GER group were greater than in the control group [32.4 +/- 3.5 impulses (imp)/s vs. 13.3 +/- 2.3 imp/s, P < 0.01]. Forty-five of 47 (95.7%) neurons responded to cardiac input and ED, which was higher than the control group (61.5%, P < 0.01). These results indicate that acute GER enhanced the excitatory responses of thoracic spinal neurons in deeper laminae of the dorsal horn to noxious cardiac stimulus.

Abstract
BACKGROUND Heartburn affects an estimated 42% of the US population. Often, patients are able to recognize symptoms and self-treat heartburn; however, patients with more persistent and/or troublesome symptoms should be evaluated by a physician or other healthcare provider. SCOPE This review focuses on the role of the primary care provider in the diagnosis and treatment of heartburn. METHODS A search was conducted on PubMed (to November 2009) and articles relevant to the management of heartburn by a primary care provider topic were selected. FINDINGS Diagnostic tools, such as endoscopy, and ambulatory pH monitoring, are recommended for advanced assessment of patients with frequent heartburn to avert misdiagnosis and to identify complications of reflux disease. Over-the-counter and prescription treatments for frequent heartburn symptoms include antacids, histamine(2)-receptor antagonists (H(2)RAs), antacid/H(2)RA combinations, and proton pump inhibitors (PPIs). Among these, PPIs represent the mainstay of acute and maintenance treatment regimens in reflux disorders and are more effective than H(2)RAs for long-term use due to the development of tolerance to the latter therapy. While once-daily PPI therapy may be sufficient in most patients, a few may require twice-daily PPI therapy to alleviate their symptoms. This review is limited by its relatively narrow focus on articles cited in PubMed. CONCLUSION The primary care provider is ideally situated to advise patients on the best treatment option for their condition and to provide follow-up care if required.

Abstract
BACKGROUND Current pharmacologic treatments for gastroparesis have been disappointing due to the limited options available. Erythromycin ethylsuccinate is a potent prokinetic agent that stimulates gastric emptying. Recently, erythromycin has been linked to the occurrences of sudden cardiac death due to QT prolongation. Azithromycin is similar to erythromycin in structure but does not have significant drug-drug interactions as seen with erythromycin. PURPOSE This study aims to determine whether azithromycin stimulates antral activity in patients with chronic gastrointestinal pain and refractory gastroparesis. METHODS Small bowel manometric data on 30 patients undergoing clinical evaluation for chronic digestive problems or documented refractory gastroparesis were reviewed. Antral activity was measured after infusion of erythromycin 250 mg intravenous and azithromycin (500 or 250 mg intravenous) given at different intervals during the small bowel manometry. The parameters measured included the total duration of effect, mean amplitude of antral contractions, duration of the highest antral contraction phase, number of cycles per minute, and the motility index. RESULTS Comparison of erythromycin and azithromycin at similar doses showed a similar positive effect on antral activity. However, comparison of erythromycin and azithromycin at the higher dose of 500 mg showed that the mean amplitude, duration of antral activity, and motility index were significantly increased with azithromycin (P < 0.05). CONCLUSIONS Azithromycin stimulates antral activity similar to erythromycin and moreover has a longer duration of effect. However, unlike erythromycin, azithromycin does not have significant drug-drug interactions and maybe a potential new medication for the treatment of gastroparesis and gastrointestinal dysmotility.

Abstract
BACKGROUND Upper gastrointestinal symptoms impose a substantial illness burden and management costs. Understanding perceptions and reasons for seeking healthcare is a prerequisite for meeting patients' needs effectively. AIM To review systematically findings on consultation frequencies for gastro-oesophageal reflux disease (GERD) and dyspepsia and patients' reasons for consultation. METHODS Systematic literature searches. RESULTS Reported consultation rates ranged from 5.4% to 56% for GERD and from 26% to 70% for dyspepsia. Consultation for GERD was associated with increased symptom severity and frequency, interference with social activities, sleep disturbance, lack of timetabled work, higher levels of comorbidity, depression, anxiety, phobia, somatization and obsessionality. Some consulted because of fears that their symptoms represented serious disease; others avoided consultation because of this. Inconsistent associations were seen with medication use. Patients were less likely to consult if they felt that their doctor would trivialize their symptoms. Few factors were consistently associated with dyspepsia consultation. However, lower socio-economic status and Helicobacter pylori infection were associated with increased consultation. CONCLUSION Patients' perceptions of their condition, comorbid factors and external reasons such as work and social factors are related to consultation rates for GERD. Awareness of these factors can guide the clinician towards a more effective strategy than one based on drug therapy alone.

Abstract
BACKGROUND Kusano et al. developed a questionnaire for the evaluation of gastroesophageal reflux disease (GERD), the frequency scale for the symptoms of GERD (FSSG). The FSSG is now widely used in Japan. We investigated the relationship between FSSG results and cardiac sphincter endoscopic findings. METHODS The subjects were 470 patients who responded to the FSSG before undergoing endoscopy. From the FSSG results, we calculated the total, acid reflux, and dysmotility scores. Endoscopic findings were assessed in terms of the anatomic-functional-pathological (AFP) classification as the A factor, or degree and type of hiatal hernia, and the valve factor, or laxity of the cardiac sphincter. The degree of esophagitis was assessed using the modified Los Angeles classification. We investigated correlations between each score and the anatomy of the cardia. RESULTS With either definition of esophagitis (grade M or greater, or grade A or greater), the total and acid reflux scores were both significantly higher in the group with reflux esophagitis than in the group without reflux esophagitis. Examination of the relationship between FSSG scores and the A factor revealed no significant differences in the total, acid reflux, or dysmotility scores whether a hiatal hernia was present or absent. Similarly, examination of the valve factor showed no significant difference in any scores between V0 and V1 versus V1 and V2, indicating no correlation between cardiac sphincter laxity and FSSG scores. CONCLUSIONS The FSSG was useful in determining whether reflux esophagitis is present, but it did not predict the anatomy of the cardia.

Abstract
OBJECTIVE To determine the prevalence of esophageal symptoms and associated symptoms of gastroesophageal reflux symptoms in 14-18 year-old high school students and the percentage of symptomatic adolescents who saw a physician or received medications. DESIGN AND SETTING A cross-sectional questionnaire administered to students at two high schools. PARTICIPANTS 1,286 completed questionnaires were analyzed. The study sample consisted of 57% Caucasians and 57% males, with a mean age of 15.7 (+/-1.3) years. INTERVENTION No intervention was used. Participants completed questionnaires only. RESULTS 714 students (56%) reported at least one esophageal or respiratory symptom. Esophageal symptoms reported were: heartburn (22%), regurgitation (21%), and dysphagia (15%). Respiratory symptoms reported were: shortness of breath (24%), wheezing (20%), and cough (18%). Students with at least one esophageal symptom were more likely to experience at least one respiratory symptom than were students with no esophageal symptoms (52% vs. 25%; p < 0.001). Cigarette, alcohol, and non-steroidal anti-inflammatory drug use were risk factors for both respiratory and esophageal symptoms. Of those experiencing one or more of these symptoms, 4% reported that the symptoms affected their daily activities, 23% visited a physician, and 25% took medication in the past year. CONCLUSIONS Esophageal symptoms of gastroesophageal reflux are frequent in adolescents. Fewer than 25% of students with gastroesophageal reflux symptoms consulted a physician and/or took medications.

Abstract
Gastro-oesophageal reflux disease (GORD) is one of the most common gastrointestinal diseases in the Western world and imposes a heavy burden on society. Although its prevalence in Asia is much lower, there is evidence that this is rapidly rising in Asia. The reported population prevalence of GORD in Eastern Asia ranges from 2.5% to 6.7% for at least weekly symptoms of heartburn and/or acid regurgitation. In general, Asians tend to have a milder spectrum of the disease. Most Asian patients have non-erosive GORD; erosive oesophagitis is less commonly seen than in the Western population. Complicated GORD, such as oesophageal stricture and Barrett's oesophagus, is seldom encountered. The mechanisms of GORD may be different in the Chinese population compared with the Western population. Chest pain is the most predominant extra-oesophageal manifestation of GORD in China, whereas an association with asthma has been shown in Japanese patients. The prevalence of GORD appears to be increasing and possible factors for GORD in Asian populations include Helicobacterpylori infection, obesity and increasing dietary fat intake. The adoption of a Western lifestyle in many developing Asian countries may account for the increasing prevalence of GORD. Proton pump inhibitors remain the most effective medical treatment for GORD. GORD will undoubtedly be a great challenge to clinicians both in primary care and in gastroenterology practice in the Asia-Pacific region in the coming years.

Abstract
BACKGROUND Prospective nationwide multicentre studies that have evaluated endoscopic findings and reflux symptoms using a well-designed questionnaire are very rare. AIM To compare the prevalence rates of and risk factors for erosive oesophagitis and non-erosive reflux disease (NERD) in the Korean population. METHODS A gastroscopic examination was performed on 25 536 subjects who visited 40 Healthcare Centers for a health check-up. A gastro-oesophageal reflux questionnaire and multivariate analysis were used to determine the risk factors for erosive oesophagitis and NERD. RESULTS 2019 (8%) and 996 subjects (4%) had erosive oesophagitis and non-erosive reflux disease, respectively; only 58% of subjects with erosive oesophagitis had reflux symptoms. Multivariate analysis showed that the risk factors for erosive oesophagitis and NERD differed, i.e. those of erosive oesophagitis were male, a Helicobacter pylori eradication history, alcohol, body mass index > or =25 and hiatal hernia. In contrast, the risk factors for NERD were female, age <40 and > or =60 vs. 40-59 years, body mass index <23 and a monthly income <$1000, glucose > or =126 mg/dL, smoking, a stooping posture at work and antibiotic usage. CONCLUSIONS The prevalence rates of erosive oesophagitis and NERD were 8% and 4%, respectively, in Korean health check-up subjects. The risk factors for erosive oesophagitis and NERD were found to differ, which indicates that their underlying pathogeneses are distinct.

Abstract
AIM: To determine the prevalence and symptoms of gastroesophageal reflux disease (GERD) in a healthy general population in relation to demographic, lifestyle and health-seeking behaviors in Shiraz, southern Iran.
METHODS: A total of 1978 subjects aged > 35 years who referred to Gastroenterohepatology Research Center and who completed a questionnaire consisting of 27 questions for GERD in relation to demographic, lifestyle and health-seeking behaviors were included in this study for a period of five months. The validity and reliability of the questionnaire were determined.
RESULTS: The prevalence of GERD was 15.4%, which was higher in females (17.3%), in rural areas (19.8%), and in illiterate subjects (21.5%) and those with a mean age of 50.25 years. The prevalence was significantly lower in subjects having fried food (14.8%), and fruit and vegetables (14.6%). More symptoms were noticed in subjects consuming pickles (22.1%), taking aspirin (21%) and in subjects with psychological distresses (27.2%) and headaches (22%). The correlation was statistically significant between GERD and halitosis (18.3%), dyspepsia (30.6%), anxiety (19.5%), nightmares (23.9%) and restlessness (18.5%). Their health seeking behavior showed that there was a significant restriction of diet (20%), consumption of herbal medicine (19%), using over-the-counter drugs (29.9%) and consulting with physicians (24.8%). Presence of GERD symptoms was also significantly related to a previous family history of the disease (22.3%).
CONCLUSION: GERD is more common in females, rural and illiterate subjects and correlated with consumption of pickles, occurrence of headache, psychological distress, dyspepsia, halitosis, anxiety, nightmare and restlessness, and a family history of GERD and aspirin intake, but the correlation was negative with consumption of fat and fiber intake.

Abstract
BACKGROUND Employers pay more than just salary for their employees. Previous studies have largely focused on direct medical and prescription drug costs of gastro-oesophageal reflux disease (GERD), and few have reported on total absenteeism costs. AIMS To examine the annual cost of illness of GERD in an employed US population by benefit category and by place of service for direct medical costs. METHODS Retrospective data analysis from 2001 to 2004. International Classification of Diseases (ICD)-9 codes (530.1, 530.10, 530.11, 530.12, 530.19, 530.81, 787.1x, 787.2x or 251.5x) were used to identify employees with and without GERD (the control group). Measures included medical and prescription drug claims, plus indirect costs for sick leave, short- and long-term disability, and workers' compensation. For a subset of the population, the direct medical claims were analysed by place of service. RESULTS Data were available for 267,269 eligible employees of which 11,653 had gastro-oesophageal reflux disease. GERD was associated with a mean incremental cost of US $3,355 per employee of which direct medical costs accounted for 65%, prescription drug costs 17%, and indirect costs 19%. The place of service 'out-patient hospital or clinic' accounted for the largest part (47%) of the difference in medical costs. CONCLUSIONS GERD is associated with substantial direct and indirect costs, which highlight the importance of managing the disease effectively.

Abstract
OBJECTIVES Extraesophageal reflux disease (EERD) is linked with serious and varied health concerns. The authors' goal was to determine the prevalence of EERD and the effect on health-related quality of life in adults within a large community-based sample. STUDY DESIGN Survey study conducted in a community setting. METHODS In the Madison, Wisconsin area, 1845 adult subjects were surveyed. Main outcome measures were frequently of GERD and laryngeal symptoms, the Medical Outcomes Trust Short Form 12 (SF-12), Voice Handicap Index (VHI), and Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaires. RESULTS More than 66% of subjects reported either GERD or laryngeal symptoms, and 26% reported both GERD and laryngeal symptoms (which reflect symptoms commonly reported for EERD). In addition, 39% of our sample took medicine for heartburn. Forty-four percent of subjects with both GERD and laryngeal symptoms reported occasional breathing difficulties, and 38% of these subjects reported a voice disorder. Significant reductions in perceived quality of general health, digestive health, and voice-related quality of life were found in subjects with both GERD and laryngeal symptoms, in comparison with subjects manifesting each symptom group alone, or in subjects with no symptoms. CONCLUSIONS The presence of GERD and laryngeal symptoms, and their concurrence, was identified in a substantial number of subjects. The GERD and laryngeal symptoms surveyed represent those most commonly reported for EERD. Because EERD has been linked with tissue damage and reductions in health-related quality of life, it is important to identify these persons and provide treatment before progression of the condition.

Effects of single or repeated administration in Japanese Helicobacter pylori-negative CYP2C19 extensive metabolizers. Dig Dis Sci 2007; 52:390-5.

Abstract
Low-dose omeprazole is superior to full-dose famotidine in maintenance therapy for gastroesophageal reflux disease, whereas "on-demand" famotidine is more effective for relief of episodes of heartburn. To explain this apparent discrepancy, intragastric pH was measured for 24-hr seven times in eight Japanese Helicobacter pylori-negative cytochrome P450 2C19 extensive metabolizers; on Days 1, 8, and 15 of repeated administration of 10 mg of omeprazole once daily and of 20 mg of famotidine twice daily and before medication. During repeated administration of omeprazole, mean intragastric pH and % time that intragastric pH > 4.0 were significantly higher and became greater. With famotidine, although these parameters were significantly higher, the degrees became smaller. Consequently, acid-suppressive effect was in the order; omeprazole < famotidine on Day 1, omeprazole approximately famotidine on Day 8, and omeprazole >famotidine on Day 15. This discrepancy possibly results from the "potentiation" of acid-suppressive effect of omeprazole and the "tolerance" phenomenon in respect to famotidine.

Abstract
Dyspepsia is a remarkably common symptom in the general population. Although multiple definitions have been used to describe the symptom, the most common explanation is that of chronic or recurrent pain or discomfort (a subjective negative feeling that may be associated with early satiety, fullness, bloating, or nausea) centered in the upper abdomen. When a thorough evaluation of a dyspeptic patient fails to identify a cause for her symptoms, the label of nonulcer or functional dyspepsia is applied. Functional dyspepsia is a heterogeneous disorder characterized by relapsing and remitting symptoms. Treatment strategies should focus on alleviating the most bothersome symptom and can be based on the proposed underlying pathophysiology. The effect of gender on mechanisms of disease, symptom presentation, and treatment response is an area of increasing interest and study. As with other functional gastrointestinal disorders, there appear to be some gender-specific features of functional dyspepsia. Specifically, gender-related differences have been observed in some studies of both the prevalence of individual dyspepsia symptoms, and in gastric emptying and proximal gastric motor function. There also appear to be gender differences in the psychosocial realm, with dyspeptic women experiencing a lesser sense of well-being than dyspeptic men, as well as an association of an abuse history with functional dyspepsia. This review will highlight specific gender differences related to the symptom presentation, pathophysiology, and approach to treatment of functional dyspepsia, while noting where differences have not been found and where further investigation is warranted.
