Abstract
The safety and utility of endotracheal intubation by paramedics in the United Kingdom is a matter of debate. Considering the controversy surrounding the safety of paramedic-performed endotracheal intubation, any interventions that enhance patient safety should be evaluated for implementation based on solid evidence of their effectiveness. A systematic review performed by Hansel and colleagues (2022) sought to assess compare video laryngoscopes against direct laryngoscopes in clinical practice. This commentary aims to critically appraise the methods used within the review by Hansel et al (2022) and expand upon the findings in the context of clinical practice.

Abstract
BACKGROUND Symptoms are essential in the clinical diagnosis of gastro-esophageal reflux disease (GERD). Questionnaires such as GerdQ have been developed as diagnostic aids. GerdQ has been thoroughly validated in well-characterized GERD patients, but has not yet been fully evaluated in a population that includes subjects with atypical symptoms. AIM To evaluate GerdQ in a population with typical and/or atypical symptoms of GERD, defined by 24-h pH monitoring. The secondary aim was to investigate the outcome of GerdQ depending on the response to proton pump inhibitor (PPI) treatment. METHODS The study included 646 subjects referred for 24-h pH monitoring due to a clinical suspicion of GERD. All subjects completed GerdQ before performing a 24-h pH monitoring. RESULTS In total, 377 (58%) subjects were diagnosed with GERD based on symptoms and 24-h pH monitoring (GERDpH). Of these, 46% had atypical main symptoms. Overall, GerdQ (at cut-off 8) predicted GERDpH with a sensitivity and specificity of 62% and 74%, respectively. A high specificity but poor sensitivity for diagnosis of GERDpH was found for atypical main symptoms such as cough, dysphagia and globus. GerdQ had a relatively high sensitivity and specificity in predicting PPI response and a PPV of 99% at cut-off 8. CONCLUSIONS GerdQ has a diagnostic value in an unselected population presenting with typical and/or atypical symptoms of GERD, but a low sensitivity for diagnosis of GERDpH was found in subjects with predominant symptoms such as cough, dysphagia and globus.

Aliment Pharmacol Ther 2017; 45:1350-1357.

Abstract
BACKGROUND The diagnosis of gastro-oesophageal reflux disease (GERD) in clinical practice is limited by the sensitivity and specificity of symptoms and diagnostic testing. AIM To determine if adding histology as a criterion and excluding patients with epigastric pain enhances the diagnosis for GERD. METHODS Patients with frequent upper gastrointestinal symptoms who had not taken a proton pump inhibitor in the previous 2 months and who had evaluable distal oesophageal biopsies were included (Diamond study: NCT00291746). Epithelial hyperplasia was identified when total epithelial thickness was at least 430 μm. Investigation-based GERD criteria were: presence of erosive oesophagitis, pathological oesophageal acid exposure and/or positive symptom-acid association probability. Symptoms were assessed using the Reflux Disease Questionnaire and a pre-specified checklist. RESULTS Overall, 127 (55%) of the 231 included patients met investigation-based GERD criteria and 195 (84%) met symptom-based criteria. Epithelial hyperplasia was present in 89 individuals, of whom 61 (69%) met investigation-based criteria and 83 (93%) met symptom-based criteria. Adding epithelial hyperplasia as a criterion increased the number of patients diagnosed with GERD on investigation by 28 [12%; number needed to diagnose (NND): 8], to 155 (67%). The proportion of patients with a symptom-based GERD diagnosis who met investigation-based criteria including epithelial hyperplasia was significantly greater when concomitant epigastric pain was absent than when it was present (P < 0.05; NND: 8). CONCLUSIONS Histology increases diagnosis of GERD and should be performed when clinical suspicion is high and endoscopy is negative. Excluding patients with epigastric pain enhances sensitivity for the diagnosis of GERD.

Gastric pH and Therapeutic Responses to Exsomeprazole in Patients With Functional Dyspepsia: Potential Clinical Implications. Am J Med Sci 2016; 352:582-592. [PMID: 27916213 DOI: 10.1016/j.amjms.2016.09.010] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2016] [Revised: 08/30/2016] [Accepted: 09/21/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND Therapy for functional dyspepsia remains a challenge. This study aimed to evaluate esomeprazole (E) versus placebo (P) regarding (1) the effectiveness in providing relief of abdominal pain or discomfort during 16 weeks of therapy in patients with functional dyspepsia having moderate or severe symptoms; (2) the effects on gastric acid suppression and (3) the relationship between symptom relief and gastric pH. METHODS Enrolled patients were randomized to E (n = 38) or P (n = 35) in a double-blind, placebo-controlled trial. Outcomes were measured at four 4-week intervals. Drug dose titrated at each visit, based on relief of abdominal symptoms. The 24-hour gastric pH was monitored at baseline, 4 and 8 weeks. RESULTS After 4 weeks, 71% of E patients (40mg) reported satisfactory symptom relief versus 34% of P patients (P < 0.001). When the dose for nonresponders (NR) was titrated to 40mg twice daily, the E relief rate increased to 82% versus 56% in P group (P < 0.05). During the next 4 weeks, with dose decreased by half in responders, E response rate declined to 69% versus 48% in P group (P < 0.10). When the dose was increased for NR during the last 4 weeks, E rate increased to 83% versus 57% in P group (P < 0.05). At 4 and 8 weeks for E responders and NR, patients׳ pH >4 value increased significantly compared to baseline. CONCLUSIONS (1) Though E 40mg once daily is superior to P, some patients benefit from 40mg twice daily; (2) E, 40mg once daily, profoundly inhibits gastric acid secretion; (3) intragastric pH monitoring before and after therapy may help address the relationship between symptomatic relief and gastric acid secretion and (4) some patients respond to monitored titrated placebo therapy.

Abstract
BACKGROUND/AIMS It remains unclear whether atrophic gastritis can affect dyspeptic symptoms. We aimed to investigate whether the extent of atrophic gastritis is associated with specific dyspeptic symptoms. METHODS Consecutive adults in a routine health-checkup program were enrolled in the study. The extent of atrophic gastritis was classified into 3 groups based on the Kimura-Takemoto criteria; the gastritis with no or little atrophy (group A: C0), the gastritis with atrophy mainly in the antrum (group B: C1 and C2), and the gastritis with atrophy in the large area of the corpus (group C: C3 and O). Upper gastrointestinal symptoms were categorized into "typical reflux symptoms," "epigastric pain syndrome (EPS)-related symptoms," and "postprandial distress syndrome (PDS)-related symptoms." RESULTS A total of 1827 patients (1009 males, mean age 45.1 years) were included in the analysis. The subgroups of atrophic gastritis were as follows: group A (n = 1218, 66.7%), group B (n = 392, 21.4%), and group C (n = 217, 11.9%). Typical reflux, EPS-related, and PDS-related symptoms were present in 10.5%, 19.8%, and 16.2% of the subjects, respectively. PDS-related and EPS-related symptoms were significantly more prevalent in the group C of male patients and the group B of female patients, respectively, compared with other groups. PDS-related and EPS-related symptoms were independently associated with the group C in males (OR, 2.123; 95% CI, 1.090-4.136) and the group B in females (OR, 2.571; 95% CI, 1.319-5.025), respectively. CONCLUSIONS The extent of atrophic gastritis appears to affect the generation of specific dyspeptic symptoms in a gender-dependent manner.

Abstract
Objective. To investigate whether patients on long-term antisecretory medication need to continue treatment to control symptoms. Methods. A double-blinded randomised placebo-controlled trial in general practices in Denmark. Patients aged 18-90 who were treated with antisecretory drugs on a long-term basis were randomized to esomeprazole 40 mg or identical placebo. Outcome measures were time to discontinuation with trial medication due to failed symptom control analysed as survival data. The proportion of patients stopping trial medication during the one-year follow-up was estimated. Results. A total of 171 patients were included with a median prior duration of antisecretory treatment of four years (range: 0.5 to 14.6 years). 86 patients received esomeprazole 40 mg and 85 patients received placebo. At 12 months, statistically significantly more patients in the placebo group had discontinued (73% (62/85)) compared with the esomeprazole group (21% (18/86); p < 0.001). Conclusions. Long-term users of antisecretory drugs showed a preference for the active drug compared to placebo. However, 27% of patients continued on placebo throughout the study and did not need to reinstitute usual treatment. One in five patients treated with esomeprazole discontinued trial medication due to unsatisfactory symptom control. Discontinuation of antisecretory treatment should be considered in long-term users of antisecretory drugs. This trial is registered with Trial registration ClinicalTrials.gov ID: NCT00120315.

Abstract
BACKGROUND Symptomatically 'silent' gastro-oesophageal reflux disease (GORD) may be underdiagnosed. OBJECTIVE To determine the prevalence of untreated GORD without heartburn and/or regurgitation in primary care. METHODS Patients were included if they had frequent upper gastrointestinal symptoms and had not taken a proton pump inhibitor in the previous 2 months (Diamond study: NCT00291746). GORD was diagnosed based on the presence of reflux oesophagitis, pathological oesophageal acid exposure, and/or a positive symptom-acid association probability. Patients completed the Reflux Disease Questionnaire (RDQ) and were interviewed by physicians using a prespecified symptom checklist. RESULTS GORD was diagnosed in 197 of 336 patients investigated. Heartburn and/or regurgitation were reported in 84.3% of patients with GORD during the physician interviews and in 93.4% of patients with GORD when using the RDQ. Of patients with heartburn and/or regurgitation not identified at physician interview, 58.1% (18/31) reported them at a 'troublesome' frequency and severity on the RDQ. Nine patients with GORD did not report heartburn or regurgitation either at interview or on the RDQ. CONCLUSIONS Structured patient-completed questionnaires may help to identify patients with GORD not identified during physician interview. In a small proportion of consulting patients, heartburn and regurgitation may not be present in those with GORD.

Abstract
BACKGROUND Approximately 25% of adults regularly experience heartburn, a symptom of gastro-oesophageal reflux disease (GORD). Most patients are treated empirically (without specific diagnostic evaluation e.g. endoscopy. Among patients who have an upper endoscopy, findings range from a normal appearance, mild erythema to severe oesophagitis with stricture formation. Patients without visible damage to the oesophagus have endoscopy negative reflux disease (ENRD). The pathogenesis of ENRD, and its response to treatment may differ from GORD with oesophagitis. OBJECTIVES Summarise, quantify and compare the efficacy of short-term use of proton pump inhibitors (PPI), H2-receptor antagonists (H2RA) and prokinetics in adults with GORD, treated empirically and in those with endoscopy negative reflux disease (ENRD). SEARCH METHODS We searched MEDLINE (January 1966 to November 2011), EMBASE (January 1988 to November 2011), and EBMR in November 2011. SELECTION CRITERIA Randomised controlled trials reporting symptomatic outcome after short-term treatment for GORD using proton pump inhibitors, H2-receptor antagonists or prokinetic agents. Participants had to be either from an empirical treatment group (no endoscopy used in treatment allocation) or from an endoscopy negative reflux disease group (no signs of erosive oesophagitis). DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted data. MAIN RESULTS Thirty-four trials (1314 participants) were included: fifteen in the empirical treatment group, fifteen in the ENRD group and four in both. In empirical treatment of GORD the risk ratio (RR) for heartburn remission (the primary efficacy variable) in placebo-controlled trials for PPI was 0.37 (two trials, 95% confidence interval (CI) 0.32 to 0.44), for H2RAs 0.77 (two trials, 95% CI 0.60 to 0.99) and for prokinetics 0.86 (one trial, 95% CI 0.73 to 1.01). In a direct comparison PPIs were more effective than H2RAs (seven trials, RR 0.66, 95% CI 0.60 to 0.73) and prokinetics (two trials, RR 0.53, 95% CI 0.32 to 0.87).In treatment of ENRD, the RR for heartburn remission for PPI versus placebo was 0.71 (ten trials, 95% CI 0.65 to 0.78) and for H2RA versus placebo was 0.84 (two trials, 95% CI 0.74 to 0.95). The RR for PPI versus H2RA was 0.78 (three trials, 95% CI 0.62 to 0.97) and for PPI versus prokinetic 0.72 (one trial, 95% CI 0.56 to 0.92). AUTHORS' CONCLUSIONS PPIs are more effective than H2RAs in relieving heartburn in patients with GORD who are treated empirically and in those with ENRD, although the magnitude of benefit is greater for those treated empirically.

Abstract
BACKGROUND Gender and gastric acid have been suggested to be independently involved in the pathophysiology of functional dyspepsia, but the interrelationship among gender, dyspeptic symptoms, and gastric acid secretion remains to be evaluated. We sought to explore this issue in dyspeptic patients. METHODS A total of 89 outpatients (male, 36; mean age, 55.6 years) with dyspeptic symptoms were analyzed. The degree of dyspeptic symptoms was evaluated and scored using a symptom questionnaire consisting of 3 subcategories: dysmotility-related symptoms, reflux-related symptoms, and epigastric pain-related symptoms. Stimulated gastric acid secretion was directly measured using an endoscopic gastrin test. RESULTS The total symptom scores and the epigastric pain-related symptom scores were significantly higher in female patients than in male patients. The dysmotility-related and reflux-related symptom scores were also higher, but not significantly, in the female patients. Multiple regression analysis of age, gender, habitual drinking, smoking, Helicobacter pylori infection, and gastric acid secretion revealed that gender and gastric hypochlorhydria, defined as less than 2.1 mEq/10 min in the endoscopic gastrin test, were significantly associated with higher dyspeptic symptom scores. The total scores and the dysmotility-related scores were significantly higher in the patients with gastric hypochlorhydria than in those with gastric non-hypochlorhydria, and this difference was found to be present only in females. CONCLUSIONS Gastric hypochlorhydria in female dyspeptic patients may be involved in the exacerbation of dyspeptic symptoms. Differences in the responsiveness to gastric hypochlorhydria between males and females may be partly responsible for the gender differences in the prevalence and severity of dyspeptic symptoms.

Abstract
We investigated the correlation between symptomatic improvement and quality of life in Japanese gastroesophageal reflux disease patients with PPI. Eighty one patients with reflux and dyspeptic symptom were enrolled. The evaluation of the symptom was used he Frequency Scale for the Symptom of GERD in 3 categories: total score of 12 questions, score related to reflux symptoms, and score related to dyspeptic symptoms and the evaluation of the quality of life was use the 8-item Short Form Health Survey in 2 categories, the physical component summary score and mental component summary score. All patients administered rabeprazole 10 mg/day for 8 weeks. We investigated the correlation between symptomatic improvement with proton pump inhibitor and quality of life. Significant symptomatic improvement was seen in the total score of 12 questions (26.7 ± 8.8 → 17.5 ± 5.9, p<0.0001), score related to reflux symptoms (14.9 ± 5.4 → 9.6 ± 3.6, p<0.0001), and score related to dyspeptic symptoms (11.8 ± 4.3 → 8.0 ± 2.9, p<0.0001). Significant improvement in quality of life was seen in the physical component summary score (47.8 ± 6.6 → 50.0 ± 5.9, p = 0.0209) and mental component summary score (47.4 ± 8.5 → 50.4 ± 5.3, p = 0.0133) with proton pump inhibitor. With proton pump inhibitor, a significant positive correlation was seen between the improvement rates in total score of 12 questions, score related to dyspeptic symptoms and in mental component summary score at 8 weeks (total score of 12 questions: r = 0.275, p = 0.0265, score related to dyspeptic symptoms: r = 0.367, p = 0.0027). In conclusion, quality of life was associated with improvement in dyspeptic symptoms with proton pump inhibitor treatment.

Abstract
BACKGROUND Patients with dyspepsia often experience troublesome symptoms. AIM To assess the burden of uninvestigated dyspepsia (symptoms, health-related quality of life [HRQL] and work productivity) before and after 8 weeks' esomeprazole treatment. METHODS Patients (n=1250) with uninvestigated dyspepsia (no endoscopy within 6 months and ≤ 2 endoscopies within 10 years) underwent a 1-week esomeprazole acid-suppression test before randomisation to 7 weeks' esomeprazole or placebo. The Reflux Disease Questionnaire (RDQ), Quality of Life in Reflux and Dyspepsia (QOLRAD) and Work Productivity and Activity Impairment (WPAI) questionnaires were completed at baseline (1-week off-treatment) and 8 weeks. WPAI results were further analysed among patients who responded to the acid-suppression test. RESULTS The highest baseline symptom score was for the RDQ dyspepsia domain, and the highest disease burden was for QOLRAD vitality and food/drink problems. After 8 weeks, significant improvements vs. placebo were observed for all RDQ and QOLRAD domains. The sub-population of acid-suppression test responders, but not the total WPAI population, had a significant work productivity improvement vs. placebo. CONCLUSIONS Uninvestigated dyspepsia is associated with high symptom load and impacts on HRQL and work productivity. Esomeprazole improves HRQL among such patients, and improves work productivity among 1-week acid-suppression trial responders. ClinicalTrials.gov identifier: NCT00251992.

Abstract
IMPORTANCE OF THE FIELD Dyspeptic symptoms are highly prevalent in the population and represent a major burden for healthcare systems. The ROME III criteria address and define two separate entities of functional dyspepsia: epigastric pain syndrome and postprandial distress syndrome. The etiology of dyspeptic symptoms is heterogeneous, underlying mechanisms are poorly understood and symptomatic improvement after drug therapy is often incomplete. AREAS COVERED IN THIS REVIEW This review of the literature included Medline data being published in the field of functional dyspepsia and different therapies. WHAT THE READER WILL GAIN The reader will gain a current, unbiased understanding of the pathophysiological mechanisms underlying functional dyspepsia and of the therapeutic regimens based on randomized, controlled trials and on the meta-analyses that have been published on different therapeutic agents. TAKE HOME MESSAGE Before starting medical treatment, a careful physical examination should exclude 'alarm symptoms'. Laboratory data, ultrasound and endoscopy are recommended in patients older than 45 - 55 years (depending on the guidelines being used). In areas with a high prevalence of Helicobacter pylori, the initial strategy includes 'test and treat' for H. pylori in addition to empiric acid suppressive therapy. Many studies have focused on the role of gastrointestinal dysmotility and hypersensitivity for dyspepsia with inconclusive results. Further therapeutic medical strategies include prokinetics, herbal preparations and psycho-/neurotopic drugs as well as additional psycho- or hypnotherapy.

Abstract
OBJECTIVE Gastroesophageal reflux disease (GERD) is thought to be less prevalent in China than in Western countries. However, essential population-based endoscopy data are lacking for this country. MATERIAL AND METHODS As part of a wider study, 3600 individuals selected randomly from the Shanghai region were asked to undergo endoscopy. Participants completed a general information questionnaire and a Chinese version of the Reflux Disease Questionnaire. When sufficient numbers were available, associations were assessed using multiple logistic regression or the Wilcoxon rank-sum test. RESULTS Of 3153 (87.6%) individuals who completed the survey, 1030 (32.7%) agreed to endoscopy and 1029 endoscopies were suitable for analysis. Symptom-defined GERD was more prevalent in the endoscopy group (4.7%) than in the non-endoscopy group (1.7%). Prevalence estimates were 6.4% for reflux esophagitis, 1.8% for endoscopically suspected esophageal metaplasia and 0.7% for hiatus hernia. Reflux esophagitis was more prevalent in patients with symptom-defined GERD than in those without (12.5% [6/48] vs. 6.1% [60/981]), and was significantly associated with reflux symptoms of any frequency or severity (OR = 2.10, 95% CI 1.13-3.89) and with negative Helicobacter pylori infection (OR = 0.44, 95% CI 0.25-0.80). Only 28.8% of participants with reflux esophagitis had heartburn and/or regurgitation symptoms. Epigastric burning was significantly more severe and frequent in participants with reflux esophagitis than in those without (p = 0.05). CONCLUSIONS Reflux esophagitis is less prevalent in China than reported in Western countries. Further work is needed to establish why reflux esophagitis appears less symptomatic in China than in Western countries.

Abstract
BACKGROUND Response to proton pump inhibitor (PPI) treatment in dyspepsia is unpredictable. AIM To identify symptoms associated with response to esomeprazole in order to target patients for empirical treatment. METHODS Eight hundred and five uninvestigated, primary care patients with upper GI symptoms that were considered to be acid-related were randomised to 2 weeks' treatment with esomeprazole 40 mg or placebo. The study population was divided into a model sample (N = 484) and a validation sample (N = 321). We developed a therapeutic index to predict PPI response from the model sample and tested this in the validation sample. RESULTS Response to PPI was found in 68% of patients (44% in placebo arm). Bothersome heartburn and early satiety were associated with increased likelihood of PPI response, whereas dull abdominal pain, pain relieved by bowel movements and nausea in women were associated with a decreased likelihood of PPI response. Patients in the validation sample could be classified as having a 'very high' (n = 55), 'high' (n = 123), 'medium' (n = 78) or 'low' (n = 65) probability of PPI response. The therapeutic gains over placebo were 55%, 31%, 20% and 22%, respectively. CONCLUSIONS In patients with uninvestigated dyspepsia, PPI responders can be reliably identified by a simple pocket chart using symptoms and patient characteristics (ClinicalTrials.gov NCT00318968).

Abstract
BACKGROUND Approximately 25% of adults regularly experience heartburn, a symptom of gastro-oesophageal reflux disease (GORD). Most patients are treated empirically (without specific diagnostic evaluation e.g. endoscopy. Among patients who have an upper endoscopy, findings range from a normal appearance, mild erythema to severe oesophagitis with stricture formation. Patients without visible damage to the oesophagus have endoscopy negative reflux disease (ENRD). The pathogenesis of ENRD, and its response to treatment may differ from GORD with oesophagitis. OBJECTIVES Summarise, quantify and compare the efficacy of short-term use of proton pump inhibitors (PPI), H2-receptor antagonists (H2RA) and prokinetics in adults with GORD, treated empirically and in those with endoscopy negative reflux disease (ENRD). SEARCH STRATEGY We searched MEDLINE (January 1966 to November 2008), EMBASE (January 1988 to November 2008), and EBMR in November 2008. SELECTION CRITERIA Randomised controlled trials reporting symptomatic outcome after short-term treatment for GORD using proton pump inhibitors, H2-receptor antagonists or prokinetic agents. Participants had to be either from an empirical treatment group (no endoscopy used in treatment allocation) or from an endoscopy negative reflux disease group (no signs of erosive oesophagitis). DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted data. MAIN RESULTS Thirty-two trials (9738 participants) were included: fifteen in the empirical treatment group, thirteen in the ENRD group and four in both. In empirical treatment of GORD the relative risk (RR) for heartburn remission (the primary efficacy variable) in placebo-controlled trials for PPI was 0.37 (two trials, 95% confidence interval (CI) 0.32 to 0.44), for H2RAs 0.77 (two trials, 95% CI 0.60 to 0.99) and for prokinetics 0.86 (one trial, 95% CI 0.73 to 1.01). In a direct comparison PPIs were more effective than H2RAs (seven trials, RR 0.66, 95% CI 0.60 to 0.73) and prokinetics (two trials, RR 0.53, 95% CI 0.32 to 0.87). In treatment of ENRD, the RR for heartburn remission for PPI versus placebo was 0.73 (eight trials, 95% CI 0.67 to 0.78) and for H2RA versus placebo was 0.84 (two trials, 95% CI 0.74 to 0.95). The RR for PPI versus H2RA was 0.78 (three trials, 95% CI 0.62 to 0.97) and for PPI versus prokinetic 0.72 (one trial, 95% CI 0.56 to 0.92). AUTHORS' CONCLUSIONS PPIs are more effective than H2RAs in relieving heartburn in patients with GORD who are treated empirically and in those with ENRD, although the magnitude of benefit is greater for those treated empirically.

Abstract
BACKGROUND A potential causal association between an increase in gastric pH and a risk of community-acquired respiratory tract infection (RTI), specifically pneumonia, has been debated in relation to the use of potent gastric acid-suppressive medication. OBJECTIVE To investigate the occurrence of community-acquired RTI, including pneumonia, in patients receiving esomeprazole versus placebo and other acid-suppressive agents in randomized clinical trials. METHODS The AstraZeneca ARIADNE safety database was searched for comparative, controlled phase II-IV randomized, blinded clinical studies with esomeprazole and standard reporting of all adverse events (AEs). Pooled AE data were presented according to treatment comparison (esomeprazole versus placebo, esomeprazole 40 mg versus 20 mg daily, esomeprazole versus omeprazole, lansoprazole and/or ranitidine, respectively). Frequency and relative risk (RR), with 99% confidence interval (CI) and adjustment for time on treatment, were calculated for the following four AE categories: all RTIs; signs and symptoms potentially indicating RTI; lower RTI; and pneumonia. RESULTS Thirty-one studies were identified, in which 16 583 patients received esomeprazole and 12 044 patients received either placebo or comparator acid-suppressive drugs. The occurrence of all four categories of AEs was similar between esomeprazole and placebo (all RTIs: 9.2% versus 8.5%; signs and symptoms of RTI: 1.8% versus 1.8%; lower RTI: 1.6% versus 1.5%; and pneumonia: 0.2% in both groups). The RR estimates were as follows: all RTIs, 0.93 (99% CI 0.78, 1.11); signs and symptoms of RTI, 0.85 (99% CI 0.57, 1.27); lower RTI, 0.92 (99% CI 0.59, 1.42); and pneumonia, 0.94 (99% CI 0.29, 3.07). The distribution of RTIs by patient sex and age showed a similar pattern in esomeprazole and placebo-treated patients. The comparisons of esomeprazole with the other comparator acid-suppressive drugs showed a similar pattern with only minor numerical differences in the occurrence of RTI between the drugs. There were no significant between-group differences with esomeprazole versus placebo for all four categories of AEs according to esomeprazole dosage, treatment indication and duration of treatment. CONCLUSIONS This pooled analysis found no causal association between acid-suppressive therapy with esomeprazole and increased risk of community-acquired RTI, including pneumonia, in patients receiving this agent for gastric acid-related disorders.

Abstract
PURPOSE OF REVIEW This review critically evaluates the current status of dyspepsia and, in particular, recent advances in epidemiology, pathophysiology and management. The very definition of dyspepsia and of functional dyspepsia, in particular, continues to generate controversy; the Rome III redefinition of functional dyspepsia remains to be proven to be of clinical value. Overlap with gastroesophageal reflux and irritable bowel syndrome further complicate clinical definitions. RECENT FINDINGS Most studies of pathophysiology continue to focus on gastric sensory and motor functions, though some intriguing early data raise the possibility of an infective or immunological contribution. There have been few, if any, major breakthroughs in treatment; most recent studies address instead the niceties of Helicobacter pylori eradication and acid suppressive strategies. SUMMARY This continued lack of progress in the area can only lead one to question some very basic concepts in this disorder, such as does functional dyspepsia, as we have come to know it, really exist as a distinct entity?

Abstract
BACKGROUND Approximately 25% of adults experience heartburn, the cardinal feature of gastro-oesophageal reflux disease (GORD), at least monthly. The evaluation and treatment of patients with suspected GORD is associated with a substantial economic burden. Most patients are treated empirically (without specific diagnostic evaluation). They include a wide range of underlying oesophageal injury. The severity of oesophageal injury can only be established in those who have undergone upper endoscopy. Patients without visible damage to the oesophagus have been referred to as having endoscopy negative reflux disease (ENRD). The pathogenesis of ENRD as well as its response to treatment may differ from GORD with oesophagitis. OBJECTIVES Summarise, quantify and compare the efficacy of the short-term use of proton pump inhibitors (PPI), H2-receptor antagonists (H2RA) and prokinetics in adults with GORD, treated empirically and in those with endoscopy negative reflux disease (ENRD). SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 4, 2005), MEDLINE (January 1966 to December 2005), EMBASE (January 1988 to December 2005). SELECTION CRITERIA Randomised controlled trials focussing on symptomatic outcome after short-term treatment for GORD using proton pump inhibitors, H2-receptor antagonists or prokinetic agents. Studies were included provided that participants could be classified in the empirical treatment group (no endoscopy used in treatment allocation) or in the endoscopy negative reflux disease group (no endoscopic signs of erosive oesophagitis). DATA COLLECTION AND ANALYSIS Two reviewers independently assessed trial quality and extracted data. MAIN RESULTS Thirty-one trials (9457 participants) were included: fifteen in the empirical treatment group, twelve in the ENRD group and four in both. In empirical treatment of GORD the relative risk (RR) for heartburn remission (the primary efficacy variable) in placebo-controlled trials for PPI was 0.37 (two trials, 95% confidence interval (CI) 0.32 to 0.44), for H2RAs 0.77 (two trials, 95% CI 0.60 to 0.99) and for prokinetics 0.86 (one trial, 95% CI 0.73 to 1.01).
