Abstract
The aim of our study was to identify feeding and gastrointestinal system (GIS) problems in children with cerebral palsy (CP), and to evaluate the relationship between these problems and the severity of CP. A total of 120 children with CP were enrolled consecutively into the study (67 males, 53 females; mean age: 6.0±2.4 years; range: 2-12 years). The children were classified according to the Swedish classification as diplegic, hemiplegic, or quadriplegic. Severity of CP was classified based on the Gross Motor Function Classification System. The amount of time that the caregiver allocated to mealtimes, modifications of the food, as well as feeding and GIS problems was evaluated. Feeding dysfunction was classified as mild, moderate, or severe. Comparisons of GIS and feeding disorders and the severity of CP were carried out using χ test. The results indicated lack of appetite in 46 of the 120 children (38.3%), sialorrhea in 37 (30.8%), constipation in 30 (25%), difficulty in swallowing in 23 (19.2%), and feeding dysfunction in 26 (21.7%). On the basis of the Gross Motor Function Classification System (GMFCS), the incidence of GIS problems and feeding dysfunction was found to be significantly higher in the children classified in the severe group. The time taken to consume meals was significantly longer among children with feeding dysfunction. Feeding and GIS problems are frequent in children with CP, and more marked in those with severe CP. Approximately one fourth of children with CP suffer from feeding dysfunction, and more time has to be allocated to consume meals.

Abstract
OBJECTIVE: This study was conducted to review the etiological factors and diseases associated with pediatric noncystic fibrosis bronchiectasis in a tertiary care center in Saudi Arabia. MATERIALS AND METHODS: A retrospective review of all patients with confirmed noncystic fibrosis (Non-CF) bronchiectasis by chest X-ray and/or CT chest in a pulmonary clinic during the period 1993–2005 at a tertiary care center in Riyadh. RESULTS: A total of 151 cases were diagnosed as Non-CF bronchiectasis. Seventy-five (49.7%) were male, 76 (50.3%) were female; 148 (98%) are alive and 3 (2%) died. The southwestern regions constituted 72 (50%) of the cases. There was a period of (5 ± 3.2) years between the start of symptoms and diagnosis of bronchiectasis. More than two-thirds of the patients had cough, tachypnea, wheezing, sputum production and failure to thrive. Ninety-one (60%) had associated diseases: Pulmonary diseases in 48 (32%), immunodeficiency in 27 (18%), central nervous system anomalies in 10 (7%), cardiac in 10 (7%) and asthma in 103 (68%) of the patients. Left lower lobe was commonly involved in 114 (76%) patients. Sixty-eight (67%) were found to have sinusitis. More than two-thirds of patients had two or more associated diseases. Forty-nine (32%) developed gastroesophageal reflux. Hemophilus influenza was cultured in 56 (37%), strept pneumoniae in 25 (17%) and pseudomonas aeruginosa in 24 (16%) of the patients. Eighty percent of the patients who had pulmonary function test had abnormal changes. Disease progression was related to development of symptoms before 5 years of age, persistent atelectasis and right lower lobe involvement (P< 0.05). CONCLUSION: Non-CF bronchiectasis should be included in the differential diagnosis of recurrent chest infection in Saudi Arabia. Early diagnosis and identification of associated diseases is needed to prevent progression of the disease.

Abstract
CONTEXT The relationship between gastroesophageal reflux disease (GERD) and asthma in children has been investigated; however, the nature of the association (if any) between these 2 conditions is unclear. OBJECTIVE We performed a systematic review of the literature to examine the association between GERD and asthma in children. METHODS A search of the medical literature was conducted by using PubMed and Embase (1966 through December 2008). Full-length articles in English that described at least 20 subjects younger than 18 years were included if they reported the prevalence of GERD (symptoms, pH studies, endoscopy/histology) in individuals with asthma or the prevalence of asthma in individuals with GERD. We calculated pooled odds ratios from studies that examined control groups, and we pooled prevalence estimates from all studies. RESULTS A total of 20 articles that described 5706 patients fulfilled the inclusion and exclusion criteria. Seventeen studies used objective methods for documenting reflux (eg, pH probe, contrast imaging, impedance, esophagogastroduodenoscopy), 2 studies relied on symptom-based questionnaires, and 1 study used diagnostic codes. Most studies (n = 19) examined the prevalence of GERD in 3726 individuals with asthma and reported highly variable estimates (19.3%-80.0%) and a pooled average of 22.8% with GERD symptoms, 62.9% of 789 patients with abnormal esophageal pH, and 34.8% of 89 patients with esophagitis. Only 5 studies included controls and enrolled 1314 case-patients with asthma and 2434 controls without asthma. The average prevalence of GERD was 22.0% in asthma cases and 4.8% in controls (pooled odds ratio: 5.6 [95% confidence interval: 4.3-6.9]). CONCLUSIONS There is a possible association between GERD and asthma in pediatric patients seen with asthma in referral settings. However, because of methodologic limitations of existing studies, the paucity of population-based studies, and a lack of longitudinal studies, several aspects of this association are unclear.

Abstract
OBJECTIVE To develop a North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) and European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) international consensus on the diagnosis and management of gastroesophageal reflux and gastroesophageal reflux disease in the pediatric population. METHODS An international panel of 9 pediatric gastroenterologists and 2 epidemiologists were selected by both societies, which developed these guidelines based on the Delphi principle. Statements were based on systematic literature searches using the best-available evidence from PubMed, Cumulative Index to Nursing and Allied Health Literature, and bibliographies. The committee convened in face-to-face meetings 3 times. Consensus was achieved for all recommendations through nominal group technique, a structured, quantitative method. Articles were evaluated using the Oxford Centre for Evidence-based Medicine Levels of Evidence. Using the Oxford Grades of Recommendation, the quality of evidence of each of the recommendations made by the committee was determined and is summarized in appendices. RESULTS More than 600 articles were reviewed for this work. The document provides evidence-based guidelines for the diagnosis and management of gastroesophageal reflux and gastroesophageal reflux disease in the pediatric population. CONCLUSIONS This document is intended to be used in daily practice for the development of future clinical practice guidelines and as a basis for clinical trials.

Abstract
Gastroesophageal reflux disease (GERD) may cause, trigger or exacerbate many pulmonary diseases. The physiological link between GERD and pulmonary disease has been extensively studied in chronic cough and asthma. A primary care physician often encounters patients with extra esophageal manifestations of GERD in the absence of heartburn. Patients may present with symptoms involving the pulmonary system; noncardiac chest pain; and ear, nose and throat disorders. Local irritation in the esophagus can cause symptoms that vary from indigestion, like chest discomfort and abdominal pain, to coughing and wheezing. If the gastric acid reaches the back of the throat, it may cause a bitter taste in the mouth and/or aspiration of the gastric acid into the lungs. The acid can cause throat irritation, postnasal drip and hoarseness, as well as recurrent cough, chest congestion and lung inflammation leading to asthma and/or bronchitis/ pneumonia. This clinical review examines the potential pathophysiological mechanisms of pulmonary manifestations of GERD. It also reviews relevant clinical information concerning GERD-related chronic cough and asthma. Finally, a potential management strategy for GERD in pulmonary patients is discussed.

Abstract
OBJECTIVES To develop an international consensus on the definition of gastroesophageal reflux disease (GERD) in the pediatric population. METHODS Using the Delphi process, a set of statements was developed and voted on by an international panel of eight pediatric gastroenterologists. Statements were based on systematic literature searches using Medline, EMBASE, and CINAHL. Voting was conducted using a six-point scale, with consensus defined, a priori, as agreed by 75% of the group. The strength of each statement was assessed using the GRADE system. RESULTS There were four rounds of voting. In the final vote, consensus was reached on 98% of the 59 statements. In this vote, 95% of the statements were accepted by seven of eight voters. Consensus items of particular note were: (i) GERD is present when reflux of gastric contents causes troublesome symptoms and/or complications, but this definition is complicated by unreliable reporting of symptoms in children under the age of approximately 8 years; (ii) histology has limited use in establishing or excluding a diagnosis of GERD; its primary role is to exclude other conditions; (iii) Barrett's esophagus should be defined as esophageal metaplasia that is intestinal metaplasia positive or negative; and (iv) extraesophageal conditions may be associated with GERD, but for most of these conditions causality remains to be established. CONCLUSIONS The consensus statements that comprise the Definition of GERD in the Pediatric Population were developed through a rigorous process. These statements are intended to be used for the development of future clinical practice guidelines and as a basis for clinical trials.

Abstract
BACKGROUND Extra-oesophageal symptoms are thought to be common, atypical symptoms of gastro-oesophageal reflux disease (GERD) in children. AIM To investigate the prevalence of GERD in children with extra-oesophageal symptoms or of extra-oesophageal symptoms in children with GERD, and the effect of GERD therapies on extra-oesophageal symptoms. METHODS A systematic review of articles in PubMed and EMBASE. RESULTS We identified 18 relevant articles. The pooled weighted average prevalence of GERD in asthmatic children was 23%, compared with 4% in healthy controls from the same five studies. The majority of studies evaluating the relationship between apparent life-threatening event (ALTE) and GERD did not suggest a causal relationship. Seven studies reported that respiratory symptoms, sinusitis and dental erosion were significantly more prevalent in children with GERD than in controls. Data from pharmacotherapeutic trials were inconclusive and provided no support for a causal relationship between GERD and extra-oesophageal symptoms. CONCLUSIONS Possible associations exist between GERD and asthma, pneumonia, bronchiectasis, ALTE, laryngotracheitis, sinusitis and dental erosion, but causality or temporal association were not established. Moreover, the paucity of studies, small sample sizes and varying disease definitions did not allow firm conclusions to be drawn. Most trials of GERD therapies showed no improvement in extra-oesophageal symptoms in children.

Abstract
PURPOSE Symptoms of gastroesophageal reflux disease (GERD) occur in 2% to 7% of children. The manifestations of GERD can be limited to symptoms (eg, heartburn, regurgitation) or can be more complicated, such as erosive esophagitis, esophageal strictures, or Barrett esophagus. The prevalence of such GERD complications in children is unknown. The purpose of this study was to determine the prevalence of endoscopic findings of erosive esophagitis in children. PATIENTS AND METHODS All children ages 0 to 17 years, 11 months who underwent upper endoscopy that was recorded in the Pediatric Endoscopic Database System-Clinical Outcomes Research Initiative between 1999 and 2002 were included. Endoscopic reports that were incomplete or that did not include demographic features, indications for endoscopy, or endoscopic findings were excluded. Erosive esophagitis was defined either descriptively or by the Los Angeles classification. Esophageal biopsy was not evaluated. RESULTS A total of 7188 children who underwent upper endoscopy fulfilled the inclusion and exclusion criteria. Of those, 888 (12.4%) had erosive esophagitis. The median age of children with erosive esophagitis was 12.7 +/- 4.9 years versus 10.0 +/- 5.1 years in those without erosive esophagitis (P <or= 0.0001). Of those with erosive esophagitis, 55.2% (490/888) were male, compared with 48.2% (3040/6300) in those without erosive esophagitis (P = 0.0001). Erosive esophagitis was found in 29 of 531 (5.5%) children ages 0 to 1 years and progressively increased to 106 in 542 individuals (19.6%) by age 17. Hiatal hernia was found in 68 (7.7%) of children with erosive esophagitis, compared with 157 (2.5%) without erosive esophagitis (P <or= 0.0001. The prevalence of Barrett esophagus, esophageal stricture, ulcer, previous surgery, nodules, foreign body or retained food, and anatomic abnormalities was not significantly different between children with erosive esophagitis and those without. CONCLUSIONS The frequency of erosive esophagitis is slightly higher in male children and increases with age. In contrast to erosive esophagitis in adults, there were no significant variations according to race or ethnicity. Hiatal hernia is the only endoscopic observation that predicts erosive esophagitis.

Abstract
The single biggest change in the approach to treating pediatric gastroesophageal reflux disease (GERD) in recent years has been the empiric use of proton pump inhibitors (PPIs) for symptoms suspected to be those of GERD. In other words, PPIs have been used increasingly as a first-line concurrent diagnostic test and treatment before any investigation. Although this approach is useful for some patients, there are a number of caveats about its application to children. In general, these caveats are related to age per se (eg, infancy) and to age-related symptoms and severity of GERD itself. The most important caveats relate to the prescription of empiric PPI therapy in infants--which generally is to be avoided--and to how PPIs are used in older children--specifically, the advisability of empiric trials being of limited duration. Even in children with proven reflux esophagitis, GERD is not chronic and relapsing in all; thus, trials of therapy withdrawal are warranted. In light of many factors, including the burgeoning literature on potential risks of infections in acid-suppressed children and adults, caution with dose and duration of acid-suppressive drugs in children is urged. The role of antireflux surgery is also mentioned.

Abstract
BACKGROUND Respiratory manifestations represent one of the most prevalent and difficult-to-manage extra-oesophageal syndromes of gastro-oesophageal reflux disease. AIMS To review the epidemiology, pathophysiological mechanisms and therapeutic outcomes of reflux-related respiratory disorders. METHODS Search of the literature published in English using PubMed database. RESULTS There is a discrepancy between the high prevalence of reflux in asthmatics and the limited efficacy of antireflux therapies. Asthma per se may cause reflux. Patients with difficult-to-treat asthma and/or nocturnal symptoms should be screened for reflux. Reflux can induce chronic cough through different mechanisms including micro-aspiration and both local and central reflexes. Cough and reflux may precipitate each other. A meta-analysis found no significant difference between placebo and proton pump inhibitors in the resolution of cough. Encouraging results have been reported, following antireflux surgery in patients selected on the basis of pH-impedance monitoring. Attention has been drawn to obstructive sleep apnoea syndrome. CONCLUSIONS The role of gastro-oesophageal reflux disease in the pathogenesis of miscellaneous respiratory disorders has been discussed for decades and established in asthma and cough. However, no major therapeutic advances have been reported recently. Future trials should concentrate on patient selection and the control of efficacy using recently developed technologies, such as pH-impedance monitoring.

Abstract
OBJECTIVES The primary objective was to assess the safety of esomeprazole 20 or 40 mg once daily in adolescents with clinically diagnosed gastroesophageal reflux disease (GERD). A secondary aim was to assess changes in GERD symptoms after esomeprazole therapy. PATIENTS AND METHODS In this multicenter, randomized, double-blind study, adolescents ages 12 to 17 years inclusive received esomeprazole 20 or 40 mg once daily for 8 weeks. Adverse events and changes in clinical parameters (eg, physical examination, laboratory measurements) were evaluated to assess safety. Patients or their parents or guardians scored symptom severity daily, and investigators scored overall GERD symptom severity every 2 weeks using a 4-point scale. RESULTS In the 148 adolescents with safety data, treatment-related and non-treatment-related adverse events were reported by 75% and 78% of patients in the esomeprazole 20- and 40-mg groups, respectively. Twenty-two patients (14.9%) experienced adverse events that were considered related to treatment; the most common were headache (8%, 12/148), abdominal pain (3%, 4/148), nausea (2%, 3/148), and diarrhea (2%, 3/148). No serious adverse events or clinically important findings in other safety assessments were observed. At baseline, 68% (100/147) had heartburn, 63% (93/147) had epigastric pain, 57% (84/147) had acid regurgitation, and 15% (22/147) had vomiting symptoms. Symptom scores decreased significantly in both the esomeprazole 20-mg and 40-mg groups by the final study week (P < 0.0001). Investigators rated 63.1% (94/149) of the patients as having moderate or severe symptoms at baseline; at the final visit, this percentage decreased significantly to 9.3% (13/140; P < .0001). CONCLUSIONS In adolescent patients with GERD, esomeprazole 20 or 40 mg daily for 8 weeks was well tolerated, and GERD-related symptoms were significantly reduced from baseline values in both groups.

Abstract
BACKGROUND AND AIMS Our aims were to identify and characterize the glottal response to esophageal mechanostimulation in human infants. We tested the hypotheses that glottal response is related to the type of esophageal peristaltic response, stimulus volume, and respiratory phase. METHODS Ten infants (2.8 kg, SD 0.5) were studied at 39.2 wk (SD 2.4). Esophageal manometry concurrent with ultrasonography of the glottis (USG) was performed. The sensory-motor characteristics of mechanostimulation-induced esophago-glottal closure reflex (EGCR, adduction of glottal folds upon esophageal provocation) were identified. Mid-esophageal infusions of air (N = 41) were given and the temporal relationships of glottal response with deglutition, secondary peristalsis (SP), and the respiratory phase were analyzed using multinomial logistic regression models. RESULTS The frequency occurrence of EGCR (83%) was compared (P < 0.001) with deglutition (44%), SP (34%), and no esophageal responses (22%). The odds ratios (OR, 95% CI) for the coexistence of EGCR with SP (0.4, 0.06-2.2), deglutition (1.9, 0.1-26), and no response (1.9, 0.4-9.0) were similar. The response time for esophageal reflexes was 3.8 (SD 1.8) s, and for EGCR was 0.4 (SD 0.3) s (P < 0.001). Volume-response relationship was noted (1 mL vs 2 mL, P < 0.05). EGCR was noted in both respiratory phases; however, EGCR response time was faster during expiration (P < 0.05). CONCLUSION The occurrence of EGCR is independent of the peristaltic reflexes or the respiratory phase of infusion. The independent existence of EGCR suggests a hypervigilant state of the glottis to prevent retrograde aspiration during GER events.

Abstract
OBJECTIVES The purpose of this study was to trace induced gastric reflux and to examine whether it reaches the middle ear in a Mongolian gerbil model. BACKGROUND Otitis media with effusion is the most frequent middle ear disease in childhood. Gastroesophageal reflux is suspected to be a possible factor in its pathogenesis. METHODS Seventeen Mongolian gerbils were assigned to three groups: the control (phosphate-buffered saline application to the lower esophageal sphincter) and two experimental groups (Aquo-Trinitrosan [Merck, Darmstadt, Germany] application to the lower esophageal sphincter, low gastric pressure and Aquo-Trinitrosan application, higher gastric pressure). We injected Chinese ink into the stomach to trace the path of a potential gastroesophageal reflux in all three groups. The traces of ink were investigated by ear and larynx endoscopy and histology. RESULTS There were no signs of gastroesophageal reflux based on the data obtained from the control group. In animals with traceable laryngeal reflux, the ink was also shown to advance through the eustachian tube and reach the middle ear. In addition, we found that when reflux reaches the middle ear on one side, it also reaches the contralateral middle ear in most cases. CONCLUSION Gastroesophageal reflux induced by relaxation of the lower esophageal sphincter was shown to reach the middle ear in our Mongolian gerbil model. These results support recent hypotheses linking gastroesophageal reflux to the development of otitis media with effusion.

Abstract
Although recent studies suggest that gastroesophageal reflux disease (GERD) may contribute to a variety of ear, nose and throat and pulmonary diseases, the cause-and-effect relationship for the vast majority remains far from proven. In this article, the evidence supporting a possible causal association between GERD and chronic sinusitis has been reviewed. The evidence would suggest that: (i) a higher prevalence of GERD and a different esophagopharyngeal distribution of the gastric refluxate occurs in patients with chronic sinusitis unresponsive to conventional medical and surgical therapy compared to the general population; (ii) a biologically plausible pathogenetic mechanism exists whereby GERD may result in chronic sinusitis; and (iii) clinical manifestations of chronic sinusitis respond variably to antireflux therapy. While these findings suggest that GERD may contribute to the pathogenesis of chronic sinusitis in some patients, it is apparent that the quality of the evidence supporting each of these three lines of evidence is low and therefore does not conclusively establish a cause-and-effect relationship. A number of unresolved issues regarding prevalence, pathophysiological mechanism, diagnosis and treatment exist that deserve further investigation in order to solidify the relationship between GERD and chronic sinusitis. In conclusion, given the possible relationship between GERD and chronic sinusitis, until more convincing data are available, it may be prudent to investigate for GERD as a potential cofactor or initiating factor in patients with chronic sinusitis when no other etiology exists, or in those whose symptoms are unresponsive to conventional therapies.

Abstract
BACKGROUND The prevalence of Barrett's esophagus (BE) in young individuals is unclear. OBJECTIVE To estimate the prevalence of suspected BE in children and adolescent patients undergoing endoscopy. DESIGN A retrospective cross-sectional study. SETTING Prospectively collected data in the Pediatric Clinical Outcomes Research Initiative (PEDS-CORI). PATIENTS We identified patients younger than 20 years of age with suspected BE in the PEDS-CORI between 1999 and 2002; the corresponding histopathologic records were examined. MAIN OUTCOME MEASUREMENTS We analyzed the distribution of demographic and endoscopic risk factors for BE between cases and non-cases with and without suspected BE in bivariate and multivariable analyses. RESULTS We identified a total of 6731 patients who underwent upper endoscopy in 12 pediatric facilities. Only 17 patients had suspected BE (prevalence, 2.5 per 1000). Intestinal metaplasia was reported in only 9 of these patients (53%). Patients with suspected BE were older than patients without BE (median 14.7 vs 10.1 years; P = .011). Hiatus hernia was more commonly recorded in patients with suspected BE (11.8% vs 2.2%; P = .008). In a logistic regression model, both older age (odds ratio [OR] 1.13, 95% confidence interval [CI] 1.02-1.35) and hiatus hernia (OR 4.62, 95% CI 1.03-20.66) were independently associated with suspected BE. CONCLUSIONS Endoscopically suspected BE is rare (<0.25%) in children and adolescents. Older age and the presence of hiatus hernia are possible risk factors for BE in this group. LIMITATIONS Lack of standardization for identifying and recording endoscopic landmarks.

Abstract
Gastroesophageal reflux disease has frequently been implicated in a wide variety of complications beyond the esophagus. These so-called "extraesophageal" disorders range from diseases of the respiratory tract, such as asthma and bronchitis, to more remote sites and conditions such as otitis and dental erosion. Many articles proposing a link between reflux disease and a multitude of extraesophageal complications have been published, but indisputable evidence that these conditions are caused by reflux disease is rare. Much of the support for a link between reflux disease and a number of extraesophageal complications is based on the observation that reflux disease frequently coexists with other disorders. A causal link is difficult to prove, however, and this review aims to critically evaluate the available evidence, looking, where possible, at longitudinal studies, expert diagnoses, and response to acid-suppressive therapy as a means of determining the true relationship between GERD and its putative extraesophageal complications.

Abstract
The pharyngoesophageal segment of the foregut has an important function in steering clear of luminal contents from the airway, across the age spectrum from a premature neonate to an aging adult. This complex neuromuscular interaction between the esophagus and the airway is maintained by a variety of mechanisms mediated by the parasympathetic and sympathetic afferent and efferent outflows involving the myenteric plexus, glossopharyngeal and vagus cranial nerves, phrenic nerve, and brainstem nuclei. The esophageal provocation during gastroesophageal reflux events results in esophageal distention, followed by responses in the esophagus, the airway, or both. Studies involving esophageal provocation in human adults and animal models are beginning to illuminate the pathogenetic mechanisms associated with aerodigestive tract disease. However, studies pertinent to this topic in infants or children have been lacking. In this paper, we review recent advances concerning the motor responses of the esophagus and the airway ensuing upon esophageal distention. Recent advances in methods to evaluate aerodigestive responses in infants that have been validated are discussed.

Abstract
Gastroesophageal reflux disease (GERD) occurs in about two thirds of children with asthma. It may simply represent a concomitant unrelated finding or it may be responsible for provoking or worsening asthma. GERD could also be a byproduct of asthma itself. In any case, aggressive treatment of GERD seems to improve asthma outcomes. GERD should be suspected in asthma patients who do not have any known risk factors or those who are becoming difficult to treat.

Abstract
AIM To explore the prevalence of symptoms suggestive of gastro-oesophageal reflux disease (GERD) in asthmatics and controls, and to control for the possible effect of overweight. METHODS The prevalence of GERD symptoms was assessed using a questionnaire about reflux symptoms in children with asthma (n=872, mean age 10.4 y, 65% males) compared to non-asthmatic controls (n=264, mean age 10.8 y, 48% males), and a symptom score was calculated. The association between GERD symptoms and overweight (age-adjusted BMI > 25) was assessed independently. RESULTS A positive reflux symptom score was found in 19.7% of the asthmatics compared to 8.5% of the non-asthmatic control group (odds ratio (OR) 2.6, 95% CI 1.7-4.2). Overweight children reported GERD symptoms more frequently than children with normal weight (OR 1.8, 95% CI 1.2-2.6). Asthma and obesity remained significant predictors when analysed simultaneously by logistic regression analysis. One hundred and fifty-two children with asthma consented to an oesophageal pH study, and an abnormal pH study result (reflux index > 5.0) correlated positively with overweight (OR 4.9, 95% CI 2.2-11.0). CONCLUSION The prevalence of symptoms associated with gastro-oesophageal reflux was increased in children with asthma and in overweight children. Overweight and asthma were independently associated with GERD symptoms, and overweight did not explain the higher frequency of GERD in asthma patients.

Abstract
There continues to be significant controversy related to diagnostic testing for gastroesophageal reflux disease (GERD). Clearly, barium contrast fluoroscopy is superior to any other test in defining the anatomy of the upper gastrointestinal (UGI) tract. Although fluoroscopy can demonstrate gastroesophageal reflux (GER), this observation does not equate to GERD. Fluoroscopy time should not be prolonged to attempt to demonstrate GER during barium contrast radiography. There are no data to justify prolonging fluoroscopy time to perform provocative maneuvers to demonstrate reflux during barium contrast UGI series. Symptoms of GERD may be associated with physiologic esophageal acid exposure measured by intraesophageal pH monitoring, and a significant percentage of patients with abnormal esophageal acid exposure have no or minimal clinical symptoms of reflux. Abnormal acid exposure defined by pH monitoring over a 24-h period does not equate to GERD. In clinical practice presumptive diagnosis of GERD is reasonably assumed by substantial reduction or elimination of suspected reflux symptoms during therapeutic trial of acid reduction therapy.

Abstract
OBJECTIVES To determine the proportion of acid and nonacid reflux events in children with asthma suspected to have gastroesophageal reflux (GER) using combined impedance-pH monitoring, and to determine the symptom index (SI) for nonacid and acid reflux events. STUDY DESIGN This was a prospective study of children with asthma (age 5 months to 6 years) referred for evaluation of GER. Exclusion criteria were congenital anomalies, cerebral palsy, mental retardation, and cardiac disease. The children underwent a 20-hour multichannel intraluminal impedance (MII)-pH study. RESULTS A total of 24 children (17 male; mean age, 33 months) were enrolled from March 2004 to February 2005. MII-pH detected 1184 reflux events, versus 419 reflux events by pH alone; 51% (605 events) were nonacid. The proportion of nonacid reflux events decreased with time elapsed from last meal (P < .0001 by Pearson's chi2 test). A total of 555 symptoms were recorded, including 331 cases of cough, 243 of which (73.4%) were not associated with a reflux event. The SI for MII-pH was significantly different than that for the pH probe (37% vs 0%; P = .008). CONCLUSIONS Acid and nonacid reflux occurs with equal frequency in children with asthma. Most symptoms occur in the absence of a reflux event.

Abstract
OBJECTIVES A globally acceptable definition and classification of gastroesophageal reflux disease (GERD) is desirable for research and clinical practice. The aim of this initiative was to develop a consensus definition and classification that would be useful for patients, physicians, and regulatory agencies. METHODS A modified Delphi process was employed to reach consensus using repeated iterative voting. A series of statements was developed by a working group of five experts after a systematic review of the literature in three databases (Embase, Cochrane trials register, Medline). Over a period of 2 yr, the statements were developed, modified, and approved through four rounds of voting. The voting group consisted of 44 experts from 18 countries. The final vote was conducted on a 6-point scale and consensus was defined a priori as agreement by two-thirds of the participants. RESULTS The level of agreement strengthened throughout the process with two-thirds of the participants agreeing with 86%, 88%, 94%, and 100% of statements at each vote, respectively. At the final vote, 94% of the final 51 statements were approved by 90% of the Consensus Group, and 90% of statements were accepted with strong agreement or minor reservation. GERD was defined as a condition that develops when the reflux of stomach contents causes troublesome symptoms and/or complications. The disease was subclassified into esophageal and extraesophageal syndromes. Novel aspects of the new definition include a patient-centered approach that is independent of endoscopic findings, subclassification of the disease into discrete syndromes, and the recognition of laryngitis, cough, asthma, and dental erosions as possible GERD syndromes. It also proposes a new definition for suspected and proven Barrett's esophagus. CONCLUSIONS Evidence-based global consensus definitions are possible despite differences in terminology and language, prevalence, and manifestations of the disease in different countries. A global consensus definition for GERD may simplify disease management, allow collaborative research, and make studies more generalizable, assisting patients, physicians, and regulatory agencies.

Abstract
We determined the prevalence of gastroesophageal reflux disease (GERD) symptoms and the associations between GERD symptoms and asthma morbidity in a population of adolescents with asthma. Two thousand, three hundred and ninety-seven students attending six middle schools in Seattle completed the International Study of Asthma and Allergy in Children (ISAAC) written and video survey that included additional questions pertaining to GERD symptoms and asthma morbidity. Based on their responses, children were categorized as having undiagnosed current asthma, physician-diagnosed current asthma, or no asthma symptoms. The prevalence of GERD symptoms occurring at least weekly or daily was determined for each group. The asthma morbidity outcomes were emergency department visits, physician visits, missed school days, and use of inhaled medications for respiratory symptoms within the past year. Associations between GERD symptoms and asthma morbidity outcomes were determined using logistic regression. The prevalence of GERD symptoms was significantly higher among students with current asthma (19.3%; 95% confidence interval (CI), 14.9-24.2) than students with no asthma symptoms (2.5%; 95% CI, 1.8-3.4). In children with current asthma (n = 296), symptoms of GERD that occurred at least weekly were strongly associated with emergency department visits (odds ratio (OR), 5.0; 95% CI, 2.6-9.6), physician visits (OR, 2.5; 95% CI, 1.3-4.6), missed school (OR, 2.0; 95% CI, 1.1-3.7), and inhaled medication use (OR, 2.5; 95% CI, 1.3-4.7). The associations between GERD symptoms and emergency department visits, physician visits, and inhaled medication use were stronger among children with asthma who reported daily GERD symptoms (n = 14) than among children reporting weekly GERD symptoms (n = 57). The prevalence of GERD symptoms was greater in adolescents with current asthma than in those without asthma. In addition, the presence of at least weekly GERD symptoms was strongly associated with greater asthma morbidity and the use of asthma medications.

Abstract
OBJECTIVE Reflux is a common pediatric disorder and an association between reflux and otolaryngological conditions has been described. However, to prove a causal relationship a pathophysiological pathway must be identified, diagnostic test with high specificity and sensitivity must be developed and conservative or surgical treatment of reflux should be shown to predictably improve the otolaryngological problems. This review study aims at examining the available evidence for the above controversial issues. METHODS Articles on pediatric laryngopharyngeal reflux published in English during the last decade were searched using Ovid and PubMed. RESULTS A lack of consensus was found in four separate but interdependent areas: clinical manifestations, diagnostic testing, interpretation of findings and treatment. Although clinical experience and uncontrolled case series suggest that laryngopharyngeal reflux may possibly contribute to apnea, recurrent upper respiratory infections, laryngeal symptoms (mainly laryngomalacia and subglottic stenosis), sinusitis and otitis convincing data are lacking. For pediatric studies, the diagnostic role of pH monitoring, barium esophagram, scintigraphy, impedance monitoring, laryngoscopic examination, laryngeal biopsy and symptom assessment questionnaires remain to be defined. Interpretation of pharyngeal reflux events is controversial and the lack of established normative values as well as the existing variability in the diagnostic criteria (reflux definition, duration and number of pathological reflux events) limits the ability to directly compare results. Proposed laryngopharyngeal reflux treatment (lifestyle modification, medical or surgical therapy) is mostly empiric, with no significant placebo-controlled trials of treatment and outcomes. CONCLUSIONS Limited evidence exists to support a causative relationship between reflux and any otorhinolaryngological condition or the effectiveness of treatment. Epidemiological and large-scale prospective controlled studies are required to clarify these issues.

Abstract
OBJECTIVE Gastroesophageal reflux disease (GERD) has been implicated in various extra-gastroesophageal diseases, especially in the upper and lower airways (atypical GERD). The objective of the present study was to determine the frequency of gastroesophageal and extra-gastroesophageal symptoms in pediatric patients with GERD and their response to the general treatment. MATERIAL AND METHODS A retrospective study was conducted on 45 children of both sexes aged 3 months-12 years with GERD diagnosed by clinical examination and 24h single-channel pHmetry. The gastroesophageal and extra-gastroesophageal symptoms, the treatment instituted and the response of the patients to the latter were determined. RESULTS Five symptomatologic groups were identified: gastroesophageal (51.11%), pulmonary (recurrent pneumonia, 40%, and bronchial asthma, 46.67%), chronic cough (64.44%), rhinologic (chronic nasal obstruction, 68.88%, nasal secretion, 55.55%, and nose itching, 46.66%), and pharyngo-otologic (recurrent acute middle ear infection, 35.56%, and recurrent tonsillitis, 24.44%). The response to treatment (antireflux drugs, antiallergic drugs, and surgical procedures) resulted in cure in 24 patients (53.34%), while 21 continued to be symptomatic. The cure rate was 69.56% for the gastroesophageal group, 100% for the recurrent pneumonia group, 80.95% for the bronchial asthma group, 68.96% for the chronic cough group, 83.87% for the chronic nasal obstruction group, 80% for the nasal secretion group, 85.71% for the nose itching group, 100% for the recurrent acute middle ear infection group, and 90.90% for the recurrent tonsillitis group. Total treatment time was 1.8 times longer for the remission of extra-gastroesophageal symptoms. Exclusive antireflux treatment promoted full remission of the otorhinolaryngologic symptoms in 38.89% of patients (nasal-41.17%, recurrent acute middle ear infection-12.5%, and recurrent tonsillitis-18.18%). CONCLUSION GERD can cause otorhinolaryngologic symptoms in children and remission of these symptoms can be obtained with antireflux therapy.

Abstract
The management of otitis media with effusion (OME) has received much attention recently as a result of, among other factors, the development of resistant bacteria and the finding of less long-term impact of middle-ear effusion (MEE) on development than previously believed. Guidelines have recently been published for the management of OME promoting more accurate diagnosis, particularly distinguishing acute otitis media from OME, and recommending the 'judicious' use of antibacterials. Today, more emphasis is being placed on prevention of disease by reducing risk factors and the development of vaccines. The identification of susceptibility genes may lead to better understanding of the pathogenesis of otitis media, which in turn may lead to the development of more innovative and satisfactory methods for prevention and treatment.

Abstract
BACKGROUND Gastro-oesophageal reflux disease (GORD) is a chronic condition affecting up to one-quarter of the Western population. GORD is characterized by heartburn and acid regurgitation, but is reported to be associated with a spectrum of extra-oesophageal symptoms. OBJECTIVE The aim of this systematic review was to critically evaluate postulated extra-oesophageal symptoms of GORD. METHODS Extra-oesophageal symptoms were identified from population-based studies evaluating their association with GORD (either defined as heartburn and/or acid regurgitation, or diagnosed in general practice). The response of these symptoms to acid-suppressive therapy was investigated using randomized, double-blind, placebo-controlled studies. Pathogenic mechanisms were evaluated using clinical and preclinical studies. RESULTS An association between GORD and symptoms or a diagnosis of chest pain/angina, cough, sinusitis and gall-bladder disease was evident from three eligible population-based studies of GORD. Randomized placebo-controlled studies (n=20) showed that acid-suppressive therapy provides symptomatic relief of chest pain, asthma and, potentially, chronic cough and laryngitis. Mechanistic models, based on direct physical damage by refluxate or vagally mediated reflexes, support a causal role for GORD in chest pain and respiratory symptoms, but not in gall-bladder disease. CONCLUSION GORD is likely to play a causal role in chest pain and possibly asthma, chronic cough and laryngitis. Further investigation is desirable, particularly for other potential extra-oesophageal manifestations of GORD such as chronic obstructive pulmonary disease, sinusitis, bronchitis and otitis. Acid-suppressive therapy is likely to benefit patients with non-cardiac chest pain, but further placebo-controlled studies are needed for other symptoms comprising the extra-oesophageal spectrum of GORD.

Abstract
The use of proton pump inhibitors (PPIs) has become widespread in children and infants for the management of paediatric acid-related disease. Pharmacokinetic profiles of only omeprazole and lansoprazole have been well characterised in children over 2 years of age with acid-related diseases. Few data have been recently published regarding the pharmacokinetics of pantoprazole in children, and none are available for rabeprazole or esomeprazole. The metabolism of PPI enantiomers has never been studied in the paediatric population. A one-compartment model best describes the pharmacokinetic behaviour of omeprazole, lansoprazole and pantoprazole in children, with important interindividual variability for each pharmacokinetic parameter. Like adults, PPIs are rapidly absorbed in children following oral administration; the mean time to reach maximum plasma concentration varies from 1 to 3 hours. Since these agents are acid labile, their oral formulations consist of capsules containing enteric-coated granules. No liquid formulation is available for any of the PPIs. Thus, for those patients unable to swallow capsules, extemporaneous liquid preparations for omeprazole and lansoprazole have been reported; however, neither the absolute nor the relative bioavailabilities of these oral formulations have been studied in children. Intravenous formulations are available for omeprazole (in Europe), lansoprazole and pantoprazole. PPIs are rapidly metabolised in children, with short elimination half-lives of around 1 hour, similar to that reported for adults. All PPIs are extensively metabolised by the liver, primarily by cytochrome P450 (CYP) isoforms CYP2C19 and CYP3A4, to inactive metabolites, with little unchanged drug excreted in the urine. Similar to that seen in adults, the absolute bioavailability of omeprazole increases with repeated dosing in children; this phenomenon is thought to be due to a combination of decreased first-pass elimination and reduced systemic clearance. The apparent clearance (CL/F) of omeprazole, lansoprazole and pantoprazole appears to be faster for children than for adults. A higher metabolic capacity in children as well as differences in the extent of PPI bioavailability are most likely responsible for this finding. This may partly account for the need in children for variable and sometimes considerably greater doses of PPIs, on a per kilogram basis, than for adults to achieve similar plasma concentrations. Furthermore, no studies have been able to demonstrate a statistically significant correlation between age and pharmacokinetic parameters among children. Despite the small number of very young infants studied, there is some evidence for reduced PPI metabolism in newborns. The limited paediatric data regarding the impact of CYP2C19 genetic polymorphism on PPI metabolism are similar to those reported for adults, with poor metabolisers having 6- to 10-fold higher area under the concentration-time curve values compared with extensive metabolisers. Finally, because a pharmacokinetic/pharmacodynamic relationship exists for PPIs, the significant interindividual variability in their disposition may partly explain the wide range of therapeutic doses used in children. Further studies are needed to better define the pharmacokinetics of PPIs in children <2 years of age.

Abstract
STUDY OBJECTIVES Gastroesophageal reflux disease (GERD) and asthma are common causes for consultation in primary care, but the relationship between the two remains unclear. The aim of our study was to investigate the temporal relationship between first diagnoses of GERD and asthma in general practice. METHODS We used the UK General Practice Research Database to identify a cohort of patients with a first diagnosis of GERD (n = 5,653) and another cohort of patients with a first diagnosis of asthma (n = 9,712) during 1996, which we compared with age-matched and sex-matched control cohorts drawn from the general population without either diagnosis. We investigated the incidence of a GERD diagnosis among the asthma patients and control subjects, and the incidence of an asthma diagnosis among the GERD patients and control subjects during a mean follow-up period of 3 years. We calculated the relative risk (RR) of these diagnoses using Cox regression analysis and examined the risk associated with medication use using nested case-control analysis. RESULTS The incidence rates of GERD and asthma among the control cohorts were 4.4 and 3.8 per 1,000 person-years, respectively. During the follow-up period, the RR of an incident asthma diagnosis in patients with a new diagnosis of GERD was 1.2 (95% confidence interval [CI], 0.9 to 1.6), while the RR of an incident GERD diagnosis among patients with a new diagnosis of asthma was 1.5 (95% CI, 1.2 to 1.8) after adjustment for age, sex, smoking, prior comorbidity, and number of health-care contacts. This increased risk was mainly seen during the first year of follow-up. The prior use of prescription medications for asthma and GERD had no significant effects on the risk of GERD and asthma diagnosis, respectively. CONCLUSIONS Patients with asthma are at a significantly increased risk of developing GERD, mainly during the first year following diagnosis. A nonsignificant increase in the risk of developing asthma was evident among GERD patients. The relationship between GERD and asthma warrants further investigation.

Abstract
Gastroesophageal reflux (GER) is a potential trigger of asthma. Approximately 77% of asthmatics report heartburn. GER is a risk factor for asthma-related hospitalization and oral steroid burst use. Asthmatics may be predisposed to GER development because of a high prevalence of hiatal hernia and autonomic dysregulation and an increased pressure gradient between the abdominal cavity and the thorax, over-riding the lower esophageal sphincter pressure barrier. Asthma medications may potentiate GER. Potential mechanisms of esophageal acid-induced bronchoconstriction include a vagally mediated reflex, local axonal reflexes, heightened bronchial reactivity, and microaspiration, all resulting in neurogenic inflammation. Anti-reflux therapy improves asthma symptoms in approximately 70% of asthmatics with GER. A 3-month empiric trial of twice-daily proton pump inhibitor given 30 to 60 minutes before breakfast and dinner can identify asthmatics who have GER as a trigger of their asthma.

Abstract
Asthma is a well-recognized disease and one of the most common illnesses in childhood. More recently, gastroesophageal reflux disease has increasingly been appreciated as a common daily occurrence in children and adolescents. These two diagnoses often present in tandem, with their coexistence being more frequent than would be expected for a chance occurrence. The mainstay of asthma management is the regulation and control of chronic airway hyperreactivity and inflammation. Children who do not respond to standard asthma regimens should be evaluated for other sources of their pulmonary symptoms, most notably gastroesophageal reflux. Baseline assessment of pulmonary function tests followed by an empiric trial of proton pump inhibitor therapy, using double the standard doses commonly used in acid-related disorders and administered for 3 months, is a cost-effective, noninvasive diagnostic strategy. Children who fail to exhibit pulmonary symptom improvement should be evaluated for both medication compliance and proper administration. Twenty-four-hour esophageal pH monitoring with concurrent dairy recordings of their symptoms is recommended to ascertain adequacy of acid suppression and confirm the diagnosis in those who continue to have symptoms. Children with acid-related causes of their pulmonary symptoms often require long-term treatment. Studies have confirmed the efficacy, safety, and tolerability of proton pump inhibitors in the treatment of children and adolescents. Surgery should be reserved for those with severe disease and those who are unable to comply with pharmacologic treatment.

Abstract
Gastroesophageal reflux-induced diseases are among the most common disorders and are associated with classical oesophageal manifestations of gastroesophageal reflux disease (GERD) including a range of symptoms such as heartburn, acid regurgitation and chest pain, and also organic manifestations such as oesophagitis, oesophageal strictures and ulcerations, Barrett's oesophagus and oesophageal adenocarcinoma. Recognition of its impact on other organ systems, extra-oesophageal reflux diseases, such as the ear, nose and throat (ENT) region and the bronchopulmonary system, as well as its contribution to symptoms such as chest pain and sleep disturbances, is also increasing. This paper addresses the symptoms, diseases and complications in which the abnormal reflux of gastric content to the oesophagus and adjacent organ systems is believed to be a frequent contributory factor.

Abstract
BACKGROUND Cross-sectional studies indicate that gastro-oesophageal reflux disease symptoms have a prevalence of 10-20% in Western countries and are associated with obesity, smoking, oesophagitis, chest pain and respiratory disease. AIM To determine the natural history of gastro-oesophageal reflux disease presenting in primary care in the UK. METHODS Patients with a first diagnosis of gastro-oesophageal reflux disease during 1996 were identified in the UK General Practice Research Database and compared with age- and sex-matched controls. We investigated the incidence of gastro-oesophageal reflux disease, potential risk factors and comorbidities, and relative risk for subsequent oesophageal complications and mortality. RESULTS The incidence of a gastro-oesophageal reflux disease diagnosis was 4.5 per 1000 person-years (95% confidence interval: 4.4-4.7). Prior use of non-steroidal anti-inflammatory drugs, smoking, excess body weight and gastrointestinal and cardiac conditions were associated with an increased risk of gastro-oesophageal reflux disease diagnosis. Subjects with gastro-oesophageal reflux disease had an increased risk of respiratory problems, chest pain and angina in the year after diagnosis, and had a relative risk of 11.5 (95% confidence interval: 5.9-22.3) of being diagnosed with an oesophageal complication. There was an increase in mortality in the gastro-oesophageal reflux disease cohort only in the year following the diagnosis. CONCLUSIONS Gastro-oesophageal reflux disease is a disease associated with a range of potentially serious oesophageal complications and extra-oesophageal diseases.

Abstract
The association between gastroesophageal reflux disease (GERD) and extraesophageal disease is often referred to as extraesophageal reflux (EER). This article reviews EER, discussing epidemiology, pathogenesis, diagnosis, and treatment with a focus on the most studied and convincing EER disorders-asthma, cough, and laryngitis. Although EER comprises a heterogeneous group of disorders, some general characterizations can be made, as follows. First, although GERD's association with extraesophageal diseases is well-established, definitive evidence of causation has been more elusive, rendering epidemiological data scarce. Secondly, regarding the pathogenesis of EER, 2 basic models have been proposed: direct injury to extraesophageal tissue by acid and pepsin exposure or injury mediated through an esophageal reflex mechanism. Third, because heartburn and regurgitation are often absent in patients with EER, GERD may not be suspected. Even when GERD is suspected, the diagnosis may be difficult to confirm. Although endoscopy and barium esophagram remain important tools for detecting esophageal complications, they may fail to establish the presence of GERD. Even when GERD is diagnosed by endoscopy or barium esophagram, causation between GERD and extraesophageal symptoms cannot be determined. Esophageal pH is the most sensitive tool for detecting GERD, and it plays an important role in EER. However, even pH testing cannot establish GERD's causative relationship to extraesophageal symptoms. In this regard, effective treatment of GERD resulting in significant improvement or remission of the extraesophageal symptoms provides the best evidence for GERD's pathogenic role. Finally, EER generally requires more prolonged and aggressive antisecretory therapy than typical GERD requires.

Abstract
For more than a decade, investigations have examined the association between asthma and gastroesophageal reflux (GER), and have demonstrated that the presence of esophageal acid events is associated with respiratory symptoms. The most current research shows that GER is prevalent in patients with asthma, that esophageal acid may alter bronchial hyperresponsiveness, and that medical or surgical GER therapy may improve asthma outcome in selected asthma patients. Further research will build on our current knowledge base and, hopefully, enable us to better identify those patients with asthma who will most benefit from reflux therapy.

Abstract
Gastroesophageal reflux (GER) occurs throughout the day in healthy infants, children, and adolescents, as well as in adults. However, regurgitation into the pharynx and vomiting are more common in infants than in adults. This places the infant at particular risk for supraesophageal complications of GER. Despite recognition of this risk, a lack of good control data in children and an absence of placebo-controlled treatment trials provide only marginal evidence to support GER as a cause of any supraesophageal disorder in infants or children. An association of GER with "awake apnea," reactive airway disease, and recurrent pneumonia has been demonstrated. Although there is no good evidence to support the efficacy of medical therapy, surgical therapy for GER has been demonstrated to improve symptoms in selected cases with each of these symptom presentations. Although clinical experience and case series suggest that GER may possibly contribute to laryngeal disorders, sinusitis, and otitis media, convincing data are lacking. No studies have definitively demonstrated symptom improvement with medical or surgical therapy for the latter symptom presentations.

Abstract
This study was conducted to review and evaluate the published evidence for an association between gastroesophageal reflux (GER) and 3 supraesophageal pathologies: sinusitis, otitis media, and laryngeal malignancy. Relevant articles were located using MEDLINE (search limits: 1966-2001, English language, human studies). Only new data or new analyses of previous data were included. Relevant articles were designated by their level of evidence, based on published standards, and grouped by pathology. An overall grade was assigned to each group for the strength of evidence for or against an association. The search produced 152 articles, 42 of which met inclusion criteria and were reviewed in detail. There is grade C evidence for a positive association between GER and sinusitis (57 articles screened, 14 articles included); for a negative association between GER and otitis media (28 articles screened, 10 articles included); and for a positive association between GER and laryngeal malignancy (67 articles screened, 18 articles included). The published literature weakly supports a positive association between GER and both sinusitis and laryngeal malignancy, and a negative association between GER and otitis media.

Abstract
BACKGROUND AND AIMS Gastro-oesophageal reflux disease (GERD) can be associated with a variety of extra-oesophageal disorders (EED) such as chronic cough, asthma, laryngeal disorder or chest pain. The aim of the study was to estimate and compare the prevalence of EED in a population with symptomatic GERD presenting as either erosive reflux disease (ERD) or non-erosive reflux disease (NERD). METHODS Baseline data were collected from a prospective, multicentre, open cohort study (ProGERD) in which patients will be followed for 5 years after initial treatment with esomeprazole. Within the framework of this trial, all patients underwent gastroscopy and filled out a questionnaire designed to assess EED. The influence of potential prognostic factors on the prevalence of EED was analysed by multivariate (stepwise logistic regression) analysis. RESULTS 6215 patients (3303 male, 2912 female; mean age 54 years) presenting with heartburn were included. EED was detected in 32.8% of all patients. The proportion was significantly higher (P = 0.0002) in ERD patients (34.9%) than in NERD patients (30.5%). As judged from the multivariate analysis, female gender, age, oesophagitis of LA grade C/D, duration of GERD disease greater than 1 years and smoking were significantly associated with EED. ERD patients with oesophagitis of LA grade A or B did not have a significantly higher risk of EED than patients with NERD. CONCLUSIONS Patients with GERD have a high probability of experiencing EED, which may be associated with a number of prognostic factors such as duration and severity of GERD. Extra-oesophageal disorders are slightly, but statistically, more prevalent in ERD than in NERD patients.

Abstract
In adults, an estimated 4% to 10% of chronic, nonspecific laryngeal disease seen in otolaryngologic clinics is associated with gastroesophageal reflux disease (GERD). Although no such estimates exist in children, many investigators have reported extraesophageal manifestations of GERD, of which the most common is the association of GERD with asthma and chronic cough. A variety of signs and symptoms of otolaryngologic disease also have been attributed to GERD, including hoarseness, laryngitis, chronic rhinitis, sinusitis, globus pharyngeus, recurrent croup, laryngomalacia, stridor, subglottic stenosis, otalgia, vocal cord granulomas, and oropharyngeal dysphagia. However, proof of the association between these manifestations of otolaryngologic disease and GERD is sparse. Furthermore, the manifestations of otolaryngologic disease often occur in the absence of such classic systems of GERD as heartburn or chest pain. This review explores the role of GERD in otolaryngologic disease in children.

Abstract
Gastro-oesophageal reflux (GOR) is a common phenomenon occurring at any age with a benign prognosis in the majority of cases, but requiring prompt evaluation and treatment when presenting with alarm symptoms or when persisting. Complications of GOR disease (GORD) may be severe. This chapter will discuss the epidemiology, natural course, pathophysiology, clinical presentation, diagnostic and therapeutic approach towards GORD and motility disorders according to different ages. Similarities and differences between infants, children and adults will be highlighted. The superior efficacy and safety of proton pump inhibitors have recently changed the diagnostic and therapeutic recommendations in adults, and possible indications in children are discussed. Only in patients unresponsive to optimal medical treatment are further investigations to exclude other aetiologies for GORD needed (e.g. eosinophilic oesophagitis in infants, scleroderma in adults). Special patient groups such as those with congenital malformations (e.g. oesophageal atresia) are not considered, whereas neurological, respiratory and allergy-affected patients as well as Helicobacter pylori infection are briefly discussed.

Abstract
OBJECTIVES A genetic locus for pediatric reflux was proposed on chromosome 13q14, but is unconfirmed in independent kindreds. We sought to test this locus in families with multiple affected infants from our database of well characterized infants with reflux. METHODS We screened the database for families with multiple affected infants. Affected proband phenotype required histological esophagitis; affected sibling/cousin phenotype required a threshold score on a diagnostic questionnaire. Screened families were reduced to five based on pedigree, consent, and phenotypic clarity. Linkage of the phenotype with the four previously reported markers (D13S218, D13S1288, D13S1253, and D13S263) was tested, using an autosomal dominant, 70% penetrance model. Linkage required logarithm-of-odds score > or = 3. RESULTS Of 54 individuals in the five probands' generation, 21 (39%) were affected based on questionnaire, of whom nearly one half also had histological confirmation of esophagitis. Linkage to the defined region was excluded for the five families by two-point LOD scores (-1.47 at D13S218, -1.32 at D13S1288, -3.43 at D13S1253, and -3.92 at D13S263) and by multipoint (multipoint LOD scores less than -2 between D13S218 and D13S263) linkage analysis. No family demonstrated even suggestive positive linkage (i.e., LOD score >1). CONCLUSIONS In five rigorously phenotyped families with autosomal dominant pattern infantile reflux, we excluded genetic linkage to the region of 13ql4 previously identified responsible for an autosomal dominant form of pediatric reflux. These results suggest genetic heterogeneity, possibly related to phenotypic heterogeneity, in familial pediatric gastroesophageal reflux disease.
