Abstract
BACKGROUND Asthma and gastro-oesophageal reflux disease (GORD) are common medical conditions that frequently co-exist. GORD has been postulated as a trigger for asthma; however, evidence remains conflicting. Proposed mechanisms by which GORD causes asthma include direct airway irritation from micro-aspiration and vagally mediated oesophagobronchial reflux. Furthermore, asthma might precipitate GORD. Thus a temporal association between the two does not establish that GORD triggers asthma. OBJECTIVES To evaluate the effectiveness of GORD treatment in adults and children with asthma, in terms of its benefits for asthma. SEARCH METHODS The Cochrane Airways Group Specialised Register, CENTRAL, MEDLINE, Embase, reference lists of articles, and online clinical trial databases were searched. The most recent search was conducted on 23 June 2020. SELECTION CRITERIA We included randomised controlled trials comparing treatment of GORD in adults and children with a diagnosis of both asthma and GORD versus no treatment or placebo. DATA COLLECTION AND ANALYSIS A combination of two independent review authors extracted study data and assessed trial quality. The primary outcome of interest for this review was acute asthma exacerbation as reported by trialists. MAIN RESULTS The systematic search yielded a total of 3354 citations; 23 studies (n = 2872 participants) were suitable for inclusion. Included studies reported data from participants in 25 different countries across Europe, North and South America, Asia, Australia, and the Middle East. Participants included in this review had moderate to severe asthma and a diagnosis of GORD and were predominantly adults presenting to a clinic for treatment. Only two studies assessed effects of intervention on children, and two assessed the impact of surgical intervention. The remainder were concerned with medical intervention using a variety of dosing protocols. There was an uncertain reduction in the number of participants experiencing one or more moderate/severe asthma exacerbations with medical treatment for GORD (odds ratio 0.53, 95% confidence interval (CI) 0.17 to 1.63; 1168 participants, 2 studies; low-certainty evidence). None of the included studies reported data related to the other primary outcomes for this review: hospital admissions, emergency department visits, and unscheduled doctor visits. Medical treatment for GORD probably improved forced expiratory volume in one second (FEV₁) by a small amount (mean difference (MD) 0.10 L, 95% CI 0.05 to 0.15; 1333 participants, 7 studies; moderate-certainty evidence) as well as use of rescue medications (MD -0.71 puffs per day, 95% CI -1.20 to -0.22; 239 participants, 2 studies; moderate-certainty evidence). However, the benefit of GORD treatment for morning peak expiratory flow rate was uncertain (MD 6.02 L/min, 95% CI 0.56 to 11.47; 1262 participants, 5 studies). It is important to note that these mean improvements did not reach clinical importance. The benefit of GORD treatment for outcomes synthesised narratively including benefits of treatment for asthma symptoms, quality of life, and treatment preference was likewise uncertain. Data related to adverse events with intervention were generally underreported by the included studies, and those that were available indicated similar rates regardless of allocation to treatment or placebo. AUTHORS' CONCLUSIONS Effects of GORD treatment on the primary outcomes of number of people experiencing one or more exacerbations and hospital utilisation remain uncertain. Medical treatment for GORD in people with asthma may provide small benefit for a number of secondary outcomes related to asthma management. This review determined with moderate certainty that with treatment, lung function measures improved slightly, and use of rescue medications for asthma control was reduced. Further, evidence is insufficient to assess results in children, or to compare surgery versus medical therapy.

Abstract
OBJECTIVES The role of gastro-esophageal reflux disease (GERD) in poorly controlled asthma is often mentioned, but published studies have presented discordant results. Our main objective was to assess the effectiveness of GERD treatment in controlling asthma in children. METHODS We conducted a prospective study including poorly controlled asthmatic children aged 4 to 16 years. We checked the presence of acid reflux using pH monitoring. Patients with GERD were randomized into two groups; one received omeprazole for 6 months and the control group was not treated. The outcome was the score of the children asthma control test at the end of 6 months. The acid suppression was checked at the end of treatment with pH monitoring. After treatment, children with persistent acid reflux received high PPI doses and therefore were reevaluated 6 months later. RESULTS We included 102 children with poorly controlled asthma among which 59 (57.8%) had acid reflux. Gastroesophageal reflux (GER) was significantly more common in boys (p = 0.04). Treatment with omeprazole in sufficient doses improved the control of asthma in 5 children out of 6 (84.8 vs 11.5; p<.0001). Three factors appeared to be statistically associated with asthma control improvement after PPI therapy: male sex (p=.04), normal birth weight (p=.05) and a positive Prick-test (p=.05). These factors were not confirmed or were not sufficiently precise in multivariate analysis. The likelihood of a causal relationship between acid reflux and asthma, difficult to highlight with pH monitoring, was poor. CONCLUSIONS This study confirmed the high prevalence of GER in poorly controlled asthmatic children and showed the possible benefit of an efficient GER treatment in improving asthma control.

Abstract
OBJECTIVES Describe acoustic and laryngeal findings in pediatric patients with subjective dysphonia attributed to laryngopharyngeal reflux (LPR). Determine the impact of LPR on perceived voice quality using the pediatric Voice Handicap Index (pVHI). Compare these findings with age-matched normative values as well as data on pediatric patients with dysphonia due to other etiologies. METHODS Retrospective case series of pediatric patients (age 2-17 years) evaluated at a specialty pediatric voice clinic at a tertiary care children's hospital from January 1 2007 to December 31 2017 in whom LPR in whom LPR was deemed to be the most significant contributing factor for dysphonia based on physical examination and history. Patients with structural laryngeal abnormalities unrelated to LPR, such as raised lesions, stenosis, papillomatosis, or vocal fold immobility were excluded. RESULTS 163 out of 1195 evaluable patients met inclusion criteria. Of these, 87% had pVHI and 83% had acoustic data available from their first appointment for analysis. Mean total pVHI score was 24 (range: 0-81). Perturbation measures were elevated in both females (jitter 1.38%, shimmer 4.16%) and males (jitter 2.01%, shimmer 5.62%). Laryngologic assessment revealed: vocal fold changes including erythema and/or pre-nodules in 72% of patients. Cobblestoning of any portion of the pharynx was present in 67% with hypopharyngeal cobblestoning the most common, present in 64% of patients. CONCLUSION Pediatric patients with clinically diagnosed LPR have pVHI, jitter, and shimmer scores that are comparable to previously reported patients with raised lesions, scar and immobility, and values that are significantly higher than published normative data. Dysphonic children should be assessed for LPR and treated when indicated. LEVEL OF EVIDENCE 4.

Abstract
This relationship between gastroesophageal reflux and airway disorders is complex, possibly bidirectional, and not clearly defined. The tools used to investigate gastroesophageal reflux are mostly informative about involvement of gastroesophageal reflux within the gastrointestinal tract, although they are often utilized to study the relationship between gastroesophageal reflux and airway issues with are suspected to occur in relation to reflux. These modalities often lack specificity for reflux-related airway disorders. Co-incidence of gastroesophageal reflux and airway disorders does not necessarily infer causality. While much of our focus has been on managing acidity, controlling refluxate is an area that has not been traditionally aggressively pursued. Our management approach is based on some of the evidence presented, but also often from a lack of adequate study to provide further guidance.

Abstract
BACKGROUND Association between chronic airway diseases (CAD) and gastroesophageal reflux disease (GERD) is well described, but causality has not yet been conclusively established. This study evaluates the therapeutic significance of laparoscopic Thal fundoplication in children with CAD and diagnosed GERD. METHODS We performed a retrospective analysis of 182 neurologically nonimpaired children, all with medically refractory CAD and GERD undergoing laparoscopic Thal fundoplication. The clinical response, ability to wean oral and inhaled medication and satisfaction with postoperative results were evaluated. RESULTS Main symptoms disappeared completely in 68.7% of patients and were markedly improved in a further 22% of patients following surgery. Complete discontinuation of medication was achieved in 70.1-96.4% of cases and reduced in a further 1.8-23.5%. One intraoperative complication occurred (gastric perforation), however no conversion to laparotomy was necessary. Postoperative Dumping Syndrome occurred in 1% of cases and was managed dietetically. Prolonged postoperative dysphagia occurred in 4.3% of patients, but disappeared within 8 weeks in all but one case. CONCLUSIONS Our study suggests that Thal fundoplication in neurologically nonimpaired children with CAD and documented GERD is effective and safe. Children unresponsive to preoperative medical management showed significant improvement in airway symptoms together with a marked reduction in the need for medication. We conclude that laparoscopic Thal fundoplication represents a significant treatment worthy of consideration in this group of patients.

Abstract
OBJECTIVES 1. Evaluate the current evidence regarding the efficacy and safety of anti-reflux surgery for the treatment of severe gastroesophageal reflux-related airway disease in children. 2. Provide evidence based recommendations regarding indications and outcomes of anti-reflux surgery for airway disease in children. METHODS An a priori protocol was defined to identify all articles addressing anti-reflux surgery for the treatment of reflux-related airway disease in children where details regarding the diagnosis, treatment, and outcomes were clearly presented. The search was inclusive of all references available through August 30, 2013 and included electronic databases to identify candidate articles as well as a comprehensive series of crosschecks. The two authors independently determined which references met inclusion criteria, extracted data, and assigned levels of evidence. Data were pooled using a random effects model due to significant study heterogeneity. RESULTS Fourteen articles met inclusion criteria. The overall level of evidence was grade C. There was significant heterogeneity among the studies (I(2)=82.7%; p<0.001). However, each article uniformly presented cases suggesting that anti-reflux surgery is efficacious and safe in treating children with severe reflux-related respiratory disease. The pooled success rate for complete or partial resolution of symptoms after anti-reflux surgery was 0.91 (95% CI: 0.88, 0.94). The pooled success rate for complete symptom resolution after surgery was 0.72 (95% CI: 0.62, 0.83). CONCLUSION The current literature suggests that anti-reflux surgery is an effective and safe treatment for severe reflux-related airway disease. However, the level of evidence lacks strength and further investigation is warranted.

Abstract
BACKGROUND The relationship between GERD and asthma is complex. It is not yet clear whether GERD is an accompanying finding or a cause of asthma, or even if it is an aggravating factor. The aim of this study was to determine the frequency of asthma and allergic diseases in patients who underwent 24-h pH monitoring for a suspicion of GERD, including a comparison between subjects with and without GERD. METHOD Subjects who were evaluated by 24h ambulatory intraoesophageal pH monitoring were investigated for the presence of asthma and allergic disorders. All participants were subjected to a skin prick test and a complete blood count and serum levels of specific IgE. RESULTS A total of 204 subjects (49.5% male) with a mean age of 7.8±4.3 years were enrolled. A diagnosis of GERD was made in 78 (38.2%) subjects after 24h pH monitoring. The frequency of asthma in subjects with GERD was 20.5% compared to 25.4% in subjects without GERD (p=0.424). Subjects with GERD presenting with respiratory symptoms have higher incidence of asthma compared to subjects with GERD presenting with gastrointestinal symptoms (35.3% and 5.3% respectively; p=0.001). CONCLUSION Although, patients with and without GERD had comparable frequencies of asthma, our findings suggest that subjects who present with respiratory symptoms suggestive of GERD should also be evaluated for the presence of an underlying asthma.

Abstract
OBJECTIVES Studies have shown that gastroesophageal reflux disease occurs more frequently than expected in children with chronic rhinosinusitis. The objective of this study is to further understand the relationship of pediatric chronic rhinosinusitis and gastroesophageal reflux disease in children with symptoms of rhinorrhea, nasal congestion, and chronic cough. METHODS A retrospective chart review of 63 children, ages 6 months to 10 years old with rhinorrhea, nasal congestion, and chronic cough. The patients underwent maxillary cultures, adenoidectomy, and distal third esophageal biopsies. Children with esophageal biopsies showing esophagitis were classified as positive for gastroesophageal reflux disease, and maxillary antral swabs growing a high density of bacteria were classified as positive for chronic rhinosinusitis. RESULTS Six months to 5 years old children (n=43), 6 (14%) had simultaneous positive maxillary antral cultures and positive esophageal biopsies, 11 (26%) had positive esophageal biopsies alone, 23 (53%) had positive maxillary antral cultures alone, and 3 (7%) had neither. Six to 10 years old children (n=20), 9 (45%) had simultaneous positive maxillary antral cultures and positive esophageal biopsies, 1 (5%) patient had positive esophageal biopsies alone, 3 (15%) patients had positive maxillary antral cultures alone, and 7 (35%) patients had neither. Twenty-seven (42%) of the patients from the whole study had gastroesophageal reflux positive biopsies. The younger children were statistically likely to have chronic rhinosinusitis and gastroesophageal reflux disease independently of each other (p=0.0002). A direct group comparison found the younger group to have independent chronic rhinosinusitis and gastroesophageal reflux disease and the older group to have simultaneous chronic rhinosinusitis and gastroesophageal reflux disease (p=0.0006). CONCLUSION In children with the presenting symptoms of rhinorrhea, nasal congestion, and chronic cough, younger children tend to have either chronic rhinosinusitis or gastroesophageal reflux disease, whereas older children tend to have a more complicated etiology of chronic rhinosinusitis and gastroesophageal reflux disease or other. In all of these patients gastroesophageal reflux disease plays an important role, as over 40% of all patients had gastroesophageal positive biopsies.

Abstract
PURPOSE OF REVIEW Gastroesophageal reflux disease (GERD) is common in children with asthma and may be present with or without symptoms. Clinicians, influenced by position statements in national guidelines, have routinely treated children with poorly controlled asthma with various anti-GERD medications. This practice is based on the pervasive but unproven belief that GERD is an important determinant of poor asthma control. RECENT FINDINGS Clinical studies show that GERD is highly prevalent in children with asthma, with estimates as high as 80%, but nearly half of the children are asymptomatic. However, there is no conclusive evidence per se that asymptomatic GERD informs asthma control, and treatment of GERD in the few controlled trials available for review does not substantively improve asthma outcomes. In a recent large controlled clinical trial, treatment with a proton-pump inhibitor (PPI) was not only ineffective, but adverse effects were common, including an increased prevalence of symptomatic respiratory infections. SUMMARY Current evidence does not support the routine use of anti-GERD medications in the treatment of poorly controlled asthma of childhood. However large controlled trials of children symptomatic of both GERD and asthma have not been conducted, and in this case the benefits of treatment, although unproven, might outweigh the risks.

Abstract
OBJECTIVE Gastrointestinal conditions requiring surgical intervention are becoming increasingly frequent in adults with cystic fibrosis (CF) as life expectancy increases. In addition, patients with CF are at risk of specific gastrointestinal complications associated with their disease. This includes distal intestinal obstruction syndrome (DIOS), which may affect up to 15% of patients, and can present diagnostic and therapeutic challenges. The aim of this study was to determine the nature and frequency of general surgical procedures undertaken in a large cohort of adult CF patients so as to guide future care. DESIGN The medical records of all surviving adult CF patients followed at a large tertiary referral centre in the UK were scrutinised and details retrieved on those who had undergone abdominal surgery after the age of 16 years. RESULTS A total of 377 patients with CF were identified from the prospectively held database. Thirty-three patients had undergone 43 abdominal operations. The median age at surgery was 22.7 years (range 16-58 years). The three most commonly performed operations were: surgery for DIOS (n=9); cholecystectomy (n=8) and fundoplication (n=6). A past history of surgically treated meconium ileus at birth was a significant risk factor for requiring surgery for DIOS as an adult. CONCLUSIONS The treatment of DIOS-related complications is one of the main reasons for abdominal surgery in the adult CF population. The general surgical community needs to be increasingly aware of the existence of disease-related gastrointestinal conditions in adult CF patients so that treatment can be optimised.

Abstract
CONTEXT Asymptomatic gastroesophageal reflux (GER) is prevalent in children with asthma. Untreated GER has been postulated to be a cause of inadequate asthma control in children despite inhaled corticosteroid treatment, but it is not known whether treatment with proton pump inhibitors improves asthma control. OBJECTIVE To determine whether lansoprazole is effective in reducing asthma symptoms in children without overt GER. DESIGN, SETTING, AND PARTICIPANTS The Study of Acid Reflux in Children With Asthma, a randomized, masked, placebo-controlled, parallel clinical trial that compared lansoprazole with placebo in children with poor asthma control who were receiving inhaled corticosteroid treatment. Three hundred six participants enrolled from April 2007 to September 2010 at 19 US academic clinical centers were followed up for 24 weeks. A subgroup had an esophageal pH study before randomization. INTERVENTION Participating children were randomly assigned to receive either lansoprazole, 15 mg/d if weighing less than 30 kg or 30 mg/d if weighing 30 kg or more (n = 149), or placebo (n = 157). MAIN OUTCOME MEASURES The primary outcome measure was change in Asthma Control Questionnaire (ACQ) score (range, 0-6; a 0.5-unit change is considered clinically meaningful). Secondary outcome measures included lung function measures, asthma-related quality of life, and episodes of poor asthma control. RESULTS The mean age was 11 years (SD, 3 years). The mean difference in change (lansoprazole minus placebo) in the ACQ score was 0.2 units (95% CI, 0.0-0.3 units). There were no statistically significant differences in the mean difference in change for the secondary outcomes of forced expiratory volume in the first second (0.0 L; 95% CI, -0.1 to 0.1 L), asthma-related quality of life (-0.1; 95% CI, -0.3 to 0.1), or rate of episodes of poor asthma control (relative risk, 1.2; 95% CI, 0.9-1.5). Among the 115 children with esophageal pH studies, the prevalence of GER was 43%. In the subgroup with a positive pH study, no treatment effect for lansoprazole vs placebo was observed for any asthma outcome. Children treated with lansoprazole reported more respiratory infections (relative risk, 1.3 [95% CI, 1.1-1.6]). CONCLUSION In this trial of children with poorly controlled asthma without symptoms of GER who were using inhaled corticosteroids, the addition of lansoprazole, compared with placebo, improved neither symptoms nor lung function but was associated with increased adverse events.

Abstract
Asthma is the most common chronic disease in children. Prevalence has increased in the past 2 decades and has reached a plateau of approximately 9% of children in the United States, affecting about 6.7 million children. The increased prevalence of childhood asthma has paralleled the increased prevalence in childhood obesity. Changes in diet have also been implicated in the increased prevalence of asthma, among other risk factors. The main symptoms of asthma (ie, wheezing, coughing, and chest tightness) require medical evaluation and monitoring. The cornerstone of asthma management is medication therapy, frequently consisting of inhaled bronchodilators and corticosteroids and, when needed, therapy of corticosteroids by mouth. As part of the multidisciplinary management of this chronic disease, nutrition assessment and follow-up in childhood asthma is necessary to identify and address relevant nutrition-related problems. These problems can involve food-medication interactions, obesity, gastroesophageal reflux disease, food allergies, and other issues; therefore, individualized medical nutrition therapy is warranted. Finally, counseling to achieve a healthy balanced diet is recommended for overall health and weight management. A recent but small number of descriptive investigations agree that adherence to a Mediterranean dietary pattern can be associated with a decreased risk of current asthma symptoms in children. Although this evidence is promising, food interventions are required to substantiate an evidence-based foundation for medical nutrition therapy in childhood asthma. At this time, there is no known health risk if a Mediterranean diet is adopted.

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
OBJECTIVES We sought to correlate endoscopic findings with the clinical course of recurrent croup. METHODS Children were classified as having recurrent croup if they had had 2 or more episodes of barky cough, inspiratory stridor, and hoarseness. All study participants underwent direct laryngoscopy and bronchoscopy and were started on an antireflux regimen. A telephone questionnaire assessed the child's symptoms and treatment response. RESULTS Forty-seven children with recurrent croup were seen in our otolaryngology outpatient clinic. Demographics included a male-to-female ratio of 1.6 to 1 and an age range of 1 month to 11 years (median, 20 months). Thirty patients (63.8%) had a medical history of asthma, and 10 (21.3%) came with a prior diagnosis of gastroesophageal reflux. Gastroesophageal reflux-related laryngopharyngeal changes were seen during direct laryngoscopy and bronchoscopy in 87.2%. Of those with survey follow-up, 87.5% had improvement of respiratory symptoms after a 6- to 9-month course of antireflux medications. This finding was further reflected in a decreased number and duration of episodes (p < .0001). CONCLUSIONS The underlying narrowing process of recurrent croup can be attributed to gastroesophageal reflux and should be considered in any child with persistent barky cough, inspiratory stridor, and hoarseness. To confirm the diagnosis, diagnostic methods should be correlated with symptom progression after treatment initiation.

Abstract
AIM To check the utility of postcibal ultrasonography for the evaluation of reflux in relation to gastric emptying in infants with recurrent respiratory symptoms and to link imaging with clinical data. METHODS Esophageal reflux (hyperechoic retrograde filling) and gastric emptying (antral areas) were quantified before and after ingestion of a standard formula in 35 untreated infants (13 with chronic cough, 22 with recurrent bronchitis) and in 31 controls. RESULTS The prevalence of abnormal (> or =8 episodes) postcibal refluxes was 74% in patients and 3% in controls. Number, duration of the longest episode and extent of refluxes were significantly higher in patients compared to controls. Number of refluxes was higher in patients with symptomatic refluxes than in those without. Infants with recurrent bronchitis had more refluxes than those with chronic cough and controls. Extent and timing of gastric emptying were similar in patients and controls. CONCLUSION Esophageal ultrasonography is a useful and physiological test in infants with recurrent respiratory diseases, which have a high prevalence of abnormal postcibal esophageal reflux and a gastric emptying similar to that of normal controls. Esophageal reflux is more severe in subjects with recurrent bronchitis than in those with chronic cough.

Abstract
BACKGROUND There are no prospective studies that have examined for chronic cough in children without lung disease but with gastroesophageal reflux (GER). In otherwise healthy children undergoing flexible upper gastrointestinal endoscopy (esophago-gastroscopy), the aims of the study were to (1) define the frequency of cough in relation to symptoms of GER, (2) examine if children with cough and reflux esophagitis (RE) have different airway cellularity and microbiology in bronchoalveolar lavage (BAL) when compared to those without. METHODS Data specific for chronic cough (> 4-weeks), symptoms of GER and cough severity were collected. Children aged < 16-years (n = 150) were defined as 'coughers' (C+) if a history of cough in association with their GER symptoms was elicited before BAL were obtained during elective esophago-gastroscopy. Presence of esophagitis on esophageal biopsies was considered reflux esophagitis positive (E+). RESULTS C+ (n = 69) were just as likely as C- (n = 81) to have esophagitis, odds ratio 0.87 (95%CI 0.46, 1.7). Median neutrophil percentage in BAL was significantly different between groups; highest in C+E- (7, IQR 28) and lowest in C-E+ (5, IQR 6). BAL positive bacterial culture occurred in 20.7% and were more likely present in current coughers (OR 3.37, 95%CI 1.39, 8.08). Airway neutrophilia (median 20%, IQR 34) was significantly higher in those with BAL positive bacterial cultures than those without (5%, 4; p = 0.0001). CONCLUSION In children without lung disease, the common co-existence of cough with symptoms of GER is independent of the occurrence of esophagitis. Airway neutrophilia when present in these children is more likely to be related to airway bacterial infection and not to esophagitis.

Abstract
OBJECTIVES Gastro-oesophageal reflux (GOR)-related aspiration is associated with respiratory disease, but the current "gold standard" investigation, the lipid-laden macrophage index (LLMI), is flawed. A specific marker of GOR-related aspiration should originate in the stomach, but not the lung. An assay to detect gastric pepsin in the bronchoalveolar lavage (BAL) of children was developed and validated. METHODS Gastro-oesophageal reflux was diagnosed in 33 children using intra-oesophageal pH monitoring. Thirteen asymptomatic negative controls requiring endotracheal intubation for elective surgery and 5 positive control patients with observed aspiration were recruited. All subjects received a BAL; the fluid obtained was analysed for the pepsin content and the LLMI. RESULTS All subjects in the negative control group were negative for pepsin. The positive control group had a significantly greater median pepsin level (P < .01) compared with negative controls. Patients with proximal oesophageal GOR and chronic cough also had significantly elevated pepsin levels (P = .04). The LLMI was not significantly elevated by the presence of cough or GOR. CONCLUSIONS This study suggests that GOR-related aspiration plays a role in chronic cough in children with known GOR. Detecting pepsin in BAL fluid may therefore become an important adjunct in patient selection for antireflux surgery.

Abstract
PURPOSE OF REVIEW This commentary discusses recent developments in the methods available to pediatric otolaryngologists in the diagnosis of laryngopharyngeal reflux. RECENT DEVELOPMENTS The development of detachable wireless monitoring allows the otolaryngologists to perform their own pH monitoring. It can be deployed while performing other procedures, such as laryngoscopy and bronchoscopy. The procedure to insert the probe and collect data is described. SUMMARY It is hoped that the pH probe will play an important role in understanding the pathological role of pharyngeal reflux in terms of laryngeal, pharyngeal, sinus and ear pathology.

Abstract
An association between asthma and gastroesophageal reflux disease (GERD) has long been recognized both mechanistically and epidemiologically. The clinical relevance of this interplay continues to be explored, with special interest given to the role of GERD in the worsening of asthma. The effect of GERD is most frequently contemplated in patients with asthma that is difficult to control. Medical and surgical anti-reflux trials attempting to alter asthma symptoms have reported mixed but generally underwhelming results, although asthma symptom scores are generally improved following effective treatment of GERD. Many of the pharmaceutical studies can be criticised for having too short a duration or for likely incomplete acid suppression. Few trials have specifically studied pediatric populations. Because GERD is a common condition, particularly in young children, the role reflux plays in the worsening of asthma symptoms and the potential benefit on asthma of anti-reflux therapy warrants further exploration. Whether or not treating symptomatic GERD reduces the symptoms and severity of asthma in children, GERD coexisting with asthma should be aggressively treated. GERD symptoms in most patients with or without asthma can be controlled medically with continuous use of proton pump inhibitors such as omeprazole and lansoprazole and to a lesser extent by histamine H(2) receptor antagonists such as famotidine and cimetidine.

Abstract
PURPOSE Fundoplication is frequently required for gastroesophageal reflux (GER)-related respiratory disease. Correlation between esophageal pH data and respiratory symptoms is poor but may be improved by monitoring hypopharyngeal pH. Reflux to the hypopharynx is underestimated by salivary bicarbonate. The aim of this study was to determine if hypopharyngeal pH monitoring using pH 4 and pH 5 as reflux thresholds could predict children with reflux-related respiratory disease. METHODS One hundred five children aged 4 months to 12 years underwent esophageal and hypopharyngeal pH monitoring. Hypopharyngeal pH data were analyzed using pH 4 and pH 5 as reflux thresholds. pH data from 4 groups were compared: group A, control group, no GER, no respiratory symptoms (n = 20); group B, respiratory symptoms, no GER (n = 16); group C, GER, no respiratory symptoms (n = 26); and group D, both GER and respiratory symptoms (n = 37). RESULTS Comparing groups C and D, there was no significant difference in hypopharyngeal pH data. Using pH 5 as the reflux threshold, children in group B refluxed to the hypopharynx significantly more frequently than controls. This was most evident in children with wheeze. CONCLUSION Hypopharyngeal pH monitoring does not differentiate children with GER and respiratory symptoms from those with GER alone and is therefore of doubtful value in diagnosing recurrent aspiration.

Abstract
BACKGROUND An increasing prevalence of extraesophageal complications of gastroesophageal reflux (GER) has been seen. Evaluation of clinical profiles of patients submitted to prolonged esophageal pH monitoring could help to identify the patients who could benefit from the early diagnosis of GER. OBJECTIVE To evaluate the population, indications and results of esophageal pH-monitoring for the diagnosis of GER in a pediatric gastroenterology clinic. PATIENTS AND METHODS Data from 190 children and adolescents who had esophageal pH-monitoring were analyzed. A descriptive analysis of the population was performed and the children were categorized in five groups according to the age. The equipment used was a Digitrapper MKIII (Synetics) and all data were analyzed by using a software EsopHogram 5.7. Reflux index was established for analysis. RESULTS The most frequent indications for the exam were: asthma (26.8%), apnea/cyanosis (20%), recurrent pulmonary infections (18.4%), wheezing infant syndrome (15.8%) and chronic cough/horseness (11%). The most frequent groups of age for the respiratory symptoms were: asthma--above 5 years (92.2%); apnea/cyanosis--under 3 months (55.3%); recurrent pulmonary infections and wheezing infant syndrome--3 to 12 months (31.4% and 83.3%). Reflux index of patients with positive exam for GER was significantly higher in patients under 2 years than above 2 years of age. CONCLUSION Respiratory symptoms were predominant among the indications for esophageal pH-monitoring in children. The knowledge of the clinical profile of the patients who had esophageal pH monitoring could help to improve the technical quality of the exam.

Abstract
Most asthmatics have GER, and the evidence is strong that GER plays an important role in some patients who have asthma. Despite sophisticated study methods and technologically advanced diagnostic tests, the results of published studies on mechanisms have failed to provide a diagnostic test with a degree of certainty great enough to identify which patients have GER-induced or GER-exacerbated asthma and which patients will respond to antireflux therapy. The difficulties involved in establishing a definite cause-and-effect relationship between GER and asthma are real. Even positive results on such direct tests as sputum inspection and scintigraphic monitoring, both of which establish reflux into the tracheobronchial tree, do not necessarily establish cause or effect and cannot be used to predict outcomes. Ambulatory esophageal pH testing can suggest, but cannot prove, the diagnosis of GER-induced asthma, and pH testing cannot be relied on safely to make clinical decisions. A trial of a proton pump inhibitor (PPI) is indicated to assess if asthma improves subjectively and objectively, but the dose must be high enough to prevent even silent esophageal acid exposure, and the duration must be long enough to allow for detection of even subtle trends in subjective and objective respiratory improvement. Antireflux surgery remains a therapeutic option and should not be withheld if GER is a reasonable suspect in asthma exacerbations. Although strong opinions have been voiced as to whether or not a good response to PPI therapy predicts a good response to antireflux surgery, the opinions, although logical, are based on personal experience and gut feelings; a good PPI response may not necessarily predict a good surgery response. Opinions suggesting that a poor response to PPI predicts a poor response to antireflux surgery also may seem logical but are not based on clinical data; a poor PPI response may not necessarily predict a poor antireflux surgery response. When the method is found that predicts which patients who have GER and asthma will respond to antireflux treatment, the results could be profound: fewer hospitalizations for respiratory complications, less pulmonary morbidity and mortality, less need for pulmonary medications, less time lost from work, fewer visits to physicians' offices, and less illness associated with corticosteroid therapy. For the present, however, clinical judgment and good sense still are our best friends. It is not unreasonable to urge patients to alter their lifestyle: the huge volume, calorie-dense, high-fat meals eaten before bedtime are not likely to prevent GER or add to their life expectancy.

Abstract
In recent years there have been several reports suggesting an association between bronchial asthma and gastro-oesophageal reflux; however a cause and effect relationship has not been proven yet. Confirmation of such a relationship is likely to have far reaching implications on the management of asthma. Reliable assessment of this issue is hampered by the presence of various lacunae in most of the published studies. Hence it is essential to carefully examine the strength of data suggesting a link between asthma and reflux. This article critically analyses currently available literature on the subject (including published reviews, meta-analyses, and randomised clinical trials in the English language) and summarises valid conclusions that can be drawn; it also proposes a framework for future studies to resolve the issue.

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
OBJECTIVES To assess the efficacy and safety of lansoprazole in the treatment of adolescents with symptomatic, endoscopically proven, non-erosive gastroesophageal reflux disease and erosive esophagitis. METHODS Adolescents between 12 and 17 years of age with esophagitis were enrolled in this open-label trial and treated with lansoprazole 15 mg (non-erosive) or 30 mg (erosive) once daily for 8 weeks. If unhealed at week 8, those with erosive esophagitis were treated with an additional 4 weeks of lansoprazole 30 mg once daily. RESULTS Lansoprazole produced a significant reduction from baseline in the median percentage of days with reflux symptoms (91 to 43% in the 64 adolescents with non-erosive disease and 85 to 16% in the 23 adolescents with erosive esophagitis, P < or = 0.001 for each comparison). At week 8, mucosal healing had occurred in 95% (21 of 22) of those with erosive esophagitis. Treatment-related adverse events were reported by 19% of patients with non-erosive and 4% of patients with erosive esophagitis. Headache (7%), abdominal pain (5%), nausea (3%) and dizziness (3%) were the most frequently reported adverse events. One patient discontinued treatment early because of dizziness and vomiting. An elevation in mean serum gastrin from baseline (59 pg/mL at pretreatment to 80 pg/mL at final visit) was observed. CONCLUSION Lansoprazole 15 mg or 30 mg once daily reduced symptoms of gastroesophageal reflux in adolescents with non-erosive gastroesophageal reflux disease and erosive esophagitis, respectively. Lansoprazole 30 mg once daily for 8 weeks was effective in healing erosive esophagitis. Both treatment regimens were considered safe.

Abstract
Difficult asthma is defined as asthma that is not controlled despite treatment with> 800 micro g budesonide or equivalent per day. Poor control is defined as the need for bronchodilators more than three times a week, school absence of more than five days a term, or one episode or more of wheezing each month. Common causes of poor response to treatment include; wrong diagnosis, inappropriate medications or improper inhalation technique, poor adherence to medications and co-morbidity. Steroid resistant asthma is uncommon and estimated to be 1 in 1000-10000 asthmatic patients. If there is no functional improvement to prednisolone 2 mg/kg/day for 2 weeks with adherence checked by measuring serum prednisolone and cortisol levels, a fibreoptic bronchoscopic examination with bronchoalveolar lavage and large airway biopsy should be considered. Eosinophilic inflammation identified on the biopsy in a child who is unresponsive to prednisolone may benefit from alternative anti-inflammatory treatments such as cyclosporin. Neutrophilic infiltration in biopsy may benefit with macrolide antibiotics, 5-lipogenase inhibitors or theophyllines.

Abstract
BACKGROUND The role of surgery is debated for children with gastroesophageal reflux disease (GERD), particularly when they show atypical symptoms. This study was designed to evaluate the safety and outcome of laparoscopic Nissen-Rossetti fundoplication performed in a selected population of children with gastroesophageal reflux and atypical supraesophageal symptoms. METHODS This prospective study included 595 patients younger than 14 years with GERD who reported recurrent respiratory symptoms and had no benefit from standard medical treatment. Surgery was performed for 48 patients with anatomic anomalies, life-threatening events, or respiratory complications after ineffective medical treatment. The subjective and objective outcomes were evaluated. RESULTS No major intraoperative complications were experienced, and there was no recurrence of gastroesophageal reflux during a postoperative follow-up period of 12 months. The parents' final subjective evaluation of the outcomes 12 months after surgery was positive in 44 cases and negative in 4 cases. CONCLUSIONS Children with difficult-to-treat chronic respiratory symptoms must be evaluated for GERD, even if the need for surgery is low (8%), because complete eradication of reflux is mandatory. Radical treatment of GERD allows the pulmonologist to perform correct respiratory treatment and to prevent the development chronic and life-threatening complications.

Abstract
The management of gastro-oesophageal reflux disease (GERD) continues to garner vast amounts of attention among physicians who care for adults. However, there is an increasing awareness of the fact that this disease, as well as several other lifelong digestive diseases (i.e. Crohn's disease) may actually have their origins in childhood. Paediatric gastro-oesophageal reflux (GER) is likely to share a similar pathophysiology to adult GER, and mounting evidence from published preliminary data suggests a genetic susceptibility to GERD. However, further studies will be necessary to confirm this hypothesis. In children, GER has a distinct presentation from that in adults, with the diagnostic work-up based upon the patient's age as well as their presenting signs and symptoms. Like their adult counterparts, the early detection and treatment of GER in children may result in a better long-term outcome, improved quality-of-life, and a reduction in overall healthcare burden. While the treatment of GER in infants tends to be conservative (i.e. positioning during feeding, smaller feedings), its management in older children parallels that of adults and includes lifestyle changes and pharmacological therapy. However, with persistent symptoms, acid suppression is the mainstay of GERD management in both children and adults. Several studies in children have verified that acid suppression with a proton pump inhibitor is superior to histamine-2 receptor antagonists. Among the proton pump inhibitors, both lansoprazole and omeprazole have been the subject of published adult and paediatric studies demonstrating their short and long-term safety, in addition to their efficacy in a variety of oesophageal and supra-oesophageal GERD related conditions. These two proton pump inhibitors are manufactured as capsules containing enteric-coated granules that can be emptied into soft foods or liquids without compromising their pharmacological effects or pharmacokinetic properties. Lansoprazole is also available as a strawberry-flavoured suspension that is acceptable to children and as an oral disintegrating tablet.

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
BACKGROUND Gastroesophageal reflux (GER) plays a role in inducing or exacerbating asthma. METHODS We evaluated asthma outcome before and after anti-GER treatment in older children (age range, 5 to 10.5 years) who had persistent moderate asthma and were being treated with short- and long-acting bronchodilators, inhaled corticosteroids, and leukotriene antagonists. Forty-six such consecutive children underwent extended esophageal pH monitoring. Of the 27 patients (59%) who had evidence of GER disease, 18 patients underwent medical treatment (lifestyle changes, proton pump inhibitors, and prokinetics) and 9 patients opted for surgical treatment (Nissen fundoplication) of GER. Of the 19 patients with normal pH study findings, 8 patients underwent empiric medical anti-GER treatment and the remaining 11 patients served as a control group. Data on all patients were collected from 6 months prior to performing the pH studies and for 12 months after initiation of anti-GER treatment. The frequency of oral and inhaled corticosteroids, short- and long-acting bronchodilators, and leukotriene antagonists was prospectively recorded. RESULTS There was a significant reduction in the use of short- and long-acting bronchodilators as well as inhaled corticosteroids after anti-GER treatment was instituted in patients with GER disease (p < 0.05). Two patients (25%) without evidence of GER disease showed significant reduction in need for asthma medication after anti-GER treatment, but none of the patients without GER disease and no GER treatment showed any significant reduction in the need for asthma medications. CONCLUSIONS Anti-GER treatment in patients with GER disease and asthma results in a significant reduction in the requirement of asthma medications.

Abstract
EER is a disorder commonly seen in otolaryngologic practice and differs from GERD in its clinical manifestations, pathophysiology, and response to treatment. Its association with numerous disorders in children should lead otolaryngologists to consider this diagnosis in all patients with voice, airway, and swallowing complaints.

Abstract
A substantial percentage of infants, children and adolescents experience gastroesophageal reflux disease (GERD) and its accompanying symptoms, as well as disease complications. The diagnosis of GERD in children is made based upon the child's history, and data derived primarily from pH monitoring tests and endoscopy. In those children with confirmed reflux disease, the options for management parallel those recommended in adult patients, with the first step consisting of lifestyle changes. Surgical procedures may also be performed; however, these are rarely recommended prior to an adequate course of pharmacologic therapy, and appropriate case selection is important. Among the current pharmacotherapeutic options available in the US, the prokinetic agents and the acid-inhibitory agents (histamine-2 receptor antagonists, proton pump inhibitors) are the most widely used. The clinical utility of the prokinetic agents has been limited by the recent withdrawal of cisapride from the US marketplace and the potential for irreversible central nervous system complications with metoclopramide. Numerous clinical studies performed in adults, and several studies involving children, have demonstrated that the proton pump inhibitors are more effective than the histamine-2 receptor antagonists in the relief of GERD symptoms and healing of erosive esophagitis. In children, omeprazole and lansoprazole may be administered as the intact oral capsule, or in those who are unable or unwilling to swallow, the granule contents of the capsule may be mixed with soft foods (e.g. apple sauce) or fruit drinks/liquid dietary supplements prior to oral administration with no detrimental effects on pharmacokinetics, bioavailability, or pharmacodynamics. Studies performed with omeprazole and lansoprazole in children have shown pharmacokinetic parameters that closely resemble those observed in adults. In over a decade of use in adults, the proton pump inhibitor class of agents has been found to have a good safety profile. Studies involving children have also shown these agents to be well tolerated. In numerous drug-drug interaction studies performed with these two proton pump inhibitors, relatively few clinically significant interactions have been observed.

Abstract
UNLABELLED Detection of a gastroesophageal reflux in the aetiology of recurrent respiratory diseases is the main indication of continuous gastroesophageal pH-metry in children. The aim of the study was to measure the diagnostic value of a daytime esophageal pH monitoring in children with recurrent respiratory diseases. METHODS One hundred seventeen continuous esophageal pH monitoring of 5 +/- 3 year-old children presenting recurrent respiratory diseases have been reviewed. For each record, an analysis of the total record period, then the diurnal record, then the nocturnal record period was performed. The reflux index, the number of reflux per hour, and the number of long lasting reflux (> 5 min) per hour were compared between different periods (total, diurnal, and nocturnal). RESULTS For the reflux index, the sensibility, the specificity, the positive predictive value and the negative predictive value of the awake period in comparison with the continuous 24 h record, considering the same standards for both periods, were 97%, 46%, 72% and 92% respectively. The ROC graph analysis showed that the cut-off adaptation for the reflux index and for the number of reflux per hour, did not allow to improve the day pH-metry performance, since sensibility and specificity moved respectively from 66% to 56% for reflux index, and from 75% to 56% for the number of reflux per hour. CONCLUSION In children explored for recurrent respiratory diseases, the night record has a bad diagnostic value and a negative diurnal record is strongly predictive of absence of pathological gastroesophageal reflux in these children. Because of the absence of paediatric specific standards for this disorder, it is not possible to reduce the recording time to the diurnal period.

Abstract
OBJECTIVE To evaluate commonly utilized diagnostic modalities to detecting Gastroesophageal Reflux (GER). METHODS Sixty children aged 1-72 months (mean age 14.7 months) with symptoms suggestive of Gastroesosphageal Reflux (GER) were investigated and subjected to upper gastrointestinal endoscopy and esophageal biopsy (EB), gastroesophageal scintiscanning (GS) and 24 hour ambulatory pH monitoring. RESULT GER was detected in 28 (46.7%) cases by one or more diagnostic modalities. Ambulatory 24 hour pH monitoring was positive in higher proportion (43.3%) of cases in comparison to other modalities, followed by EB (38.3%) and GS (30%). Considering 24 hour pH monitoring as the gold standard, esophageal biopsy was positive in 22/26 cases (84.6%) detected by 24 hour pH monitoring with a specificity of 97.1% as compared to 17/26 cases (65.4%) by gastroesophageal scintiscanning with a specificity of 97.1%. When compared with EB results, amongst various parameters measured during 24 hour pH monitoring, Reflux index (RI) ranked highest (sensitivity 95.6 % and specificity 89.2 %) followed by duration of longest episode > 20 minutes and Euler Byrne score. Oscillatory index, calculated from tracings of pH monitoring, even though ranked lower because of its low sensitivity helped to pick up 2 cases missed by EB and RI. CONCLUSION Our results suggest that a combination of diagnostic modalities may be required to diagnose GER in young children. Ambulatory 24 hour pH monitoring appears to be the single best investigation and combining it with EB and/or GS can help to detect maximum number of cases.

Abstract
BACKGROUND A systematic literature review was conducted to assess the effect of treating reflux oesophagitis on asthma outcomes. METHODS Randomised controlled trials of reflux oesophagitis treatment in adults or children that reported asthma health outcomes were included and assessed in accordance with the standard Cochrane systematic review process. Patients were typically adults with asthma and concurrent symptomatic gastro-oesophageal reflux who received interventions that included pharmacological therapy, conservative management, and surgery. The following outcome measures were assessed: lung function, peak expiratory flow, asthma symptoms, asthma medications, and nocturnal asthma. RESULTS From 22 potentially relevant published and unpublished randomised controlled trials, 12 were included. Treatment duration ranged from 1 week to 6 months. Eight trials reported that treatment improved at least one asthma outcome, but these outcomes differed between trials. Overall, treatment of reflux oesophagitis did not consistently improve forced expiratory volume in one second (FEV(1)), peak expiratory flow rate, asthma symptoms, nocturnal asthma symptoms, or use of asthma medications in asthmatic subjects. Significant improvement in wheeze was reported in two studies. CONCLUSIONS The published literature does not consistently support treatment of reflux oesophagitis as a means of controlling asthma. Further large randomised controlled trials in subjects with a demonstrated temporal relationship between gastro-oesophageal reflux and asthma are needed. These trials should be conducted over at least 6 months to allow adequate time to observe a treatment effect.

Abstract
OBJECTIVE To determine the correlation between findings at direct laryngoscopy and bronchoscopy and presence of extraesophageal reflux disease (EERD). STUDY DESIGN Retrospective chart review METHODS Operative notes of 155 children undergoing direct laryngoscopy and bronchoscopy between 1996 and 1999 for airway symptoms for whom there was a suspicion of EERD were examined. Gastroesophageal reflux disease (GERD) was considered present if at least one test was positive (including upper GI series, pH probe, gastric scintiscan, or esophageal biopsy). RESULTS A total of 130 (84%) patients had GERD diagnosed. Ninety percent had at least one laryngotracheal abnormality: 83% had an abnormal larynx and 66% had an abnormal trachea. Laryngeal abnormalities in GERD included postglottic edema, 69%; arytenoid edema, 30%; large lingual tonsil, 16%; vocal fold edema, 12%; vocal fold nodule, 12%; ventricular obliteration, 5%; and hypopharyngeal cobblestoning, 3%. Tracheobronchial abnormalities in GERD included tracheal cobblestoning, 33%; blunting of carina, 12.5%; subglottic stenosis, 11%; increased secretions, 11%; and generalized edema or erythema, 5%. The best sensitivity or specificity was obtained by combining postglottic edema, arytenoid edema, and vocal fold edema, resulting in a sensitivity of 75% and a specificity of 67%. Positive predictive value was 100% for the combination of postglottic edema and any vocal fold or ventricular abnormality. CONCLUSION Laryngoscopy and bronchoscopy can reveal findings with a high positive predictive value for the presence of GERD. Endoscopy of the upper airway in children with clinical signs and symptoms of EERD is a promising tool for diagnosis.

Abstract
The work with the Nordic consensus report on asthma management started some years ago. The Nordic countries have common socioeconomic conditions. We acknowledge the international as well as other European guidelines providing valuable recommendations. Nevertheless, we felt the need to combine the common Nordic experiences in order to have a local statement of asthma and asthma care, based upon Nordic clinical science and tradition. The work has been rewarding and we acknowledge many valuable contributions from paediatricians, allergologists and lung physicians in all Nordic countries. The response has so far been positive and we feel that the present material reflects the main opinion of Nordic physicians taking care of asthma patients of all ages. However, the asthma and allergy research field is rapidly developing. Thus, this document should merely be regarded as a time-limited contribution to the continuing scientific discussion of this fascinating field.

Abstract
Recently, gastroesophageal reflux (GER) has been found to contribute to many types of otolaryngologic pathology in infants and children. The complaints may be intermittent and unresponsive to usual therapies, such as antimicrobial treatments. A high index of suspicion for GER and for the concept of "silent" GER (GER without overt symptoms) is necessary for accurate diagnosis and treatment of otolaryngologic manifestations of GER in these patients. In this prospective historical cohort study, the records were reviewed from 101 children who underwent esophagoscopy and biopsy as a diagnostic test for GER at the time of other otolaryngologic procedures. Significant associations were found between the presence of histologic esophagitis and asthma, recurrent croup, cough, apnea, sinusitis, stridor, laryngomalacia, subglottic stenosis, posterior glottic erythema, and posterior glottic edema. There were no complications. Esophageal biopsy is a rapid, safe and effective diagnostic test for GER that should be considered at the time of other procedures in children with selected GER-associated problems.

Abstract
OBJECTIVE To critique the English-language reports describing the effects of medical and surgical antireflux therapy on respiratory symptoms and function in patients with asthma. METHODS The Medline computerized database (1959-1999) was searched, and all publications relating to both asthma and gastroesophageal reflux disease were retrieved. RESULTS Seven of nine trials of histamine-receptor antagonists showed a treatment-related improvement in asthma symptoms, with half of the patients benefiting. Only one study identified a beneficial effect on objective measures of pulmonary function. Three of six trials of proton pump inhibitors documented improvement in asthma symptoms with treatment; benefit was seen in 25% of patients. Half of the studies reported improvement in pulmonary function, but the effect occurred in fewer than 15% of patients. In the one study that used optimal antisecretory therapy, asthma symptoms were improved in 67% of patients and pulmonary function was improved in 20%. Combined data from 5 pediatric and 14 adult studies of anti-reflux surgery indicated that almost 90% of children and 70% of adults had improvement in respiratory symptoms, with approximately one third experiencing improvements in objective measures of pulmonary function. CONCLUSIONS Fundoplication has been consistently shown to ameliorate reflux-induced asthma; results are superior to the published results of antisecretory therapy. Optimal medical therapy may offer similar results, but large studies providing support for this assertion are lacking.

Abstract
Pediatric gastroesophageal reflux (GER) and laryngopharyngeal reflux (LPR) have gained better recognition over the past few years. GER and LPR usually present as regurgitation, emesis, epigastric pain, failure to thrive, esophagitis, or stricture. Many patients suffer respiratory disorders associated with reflux. Classification of reflux, pathophysiology, manifestations of reflux, diagnosis, and management of the disease are discussed in this article.

Abstract
BACKGROUND Asthma and gastro-oesophageal reflux are both common medical conditions and often co-exist. Studies have shown conflicting results concerning the effects of lower oesophageal acidification as a trigger of asthma. Furthermore, asthma might precipitate gastro-oesophageal reflux. Thus a temporal association between the two does not establish that gastro-oesophageal reflux triggers asthma. Randomised trials of a number of treatments for gastro-oesophageal reflux in asthma have been conducted, with conflicting results. OBJECTIVES The objective of this review was to evaluate the effectiveness of treatments for gastro-oesophageal reflux in terms of their benefit on asthma. SEARCH STRATEGY The Cochrane Airways Group trials register, review articles and reference lists of articles were searched. SELECTION CRITERIA Randomised controlled trials of treatment for oesophageal reflux in adults and children with a diagnosis of both asthma and gastro-oesophageal reflux. DATA COLLECTION AND ANALYSIS Trial quality and data extraction were carried out by two independent reviewers. Authors were contacted for confirmation or more data. MAIN RESULTS Nine trials met the inclusion criteria. Interventions included proton pump inhibitors (n=3), histamine antagonists (n=5), surgery (n=1) and conservative management (n=1). Treatment duration ranged from 1 week to 6 months. A temporal association between asthma and gastro-oesophageal reflux was investigated in 4 trials and found to be present in a proportion of participants in these trials. Anti-reflux treatment did not consistently improve lung function, asthma symptoms, nocturnal asthma or the use of asthma medications. REVIEWER'S CONCLUSIONS In asthmatic subjects with gastro-oesophageal reflux, (but who were not recruited specifically on the basis of reflux-associated respiratory symptoms), there was no overall improvement in asthma following treatment for gastro-oesophageal reflux. Subgroups of patients may gain benefit, but it appears difficult to predict responders.

Abstract
A 2.5-year-old child presented with a sleep disturbance initially diagnosed as a behavioral problem. The child had several atypical symptoms of gastroesophageal reflux disease (GERD). The sleep disturbance resolved quickly after treatment of GERD. GERD is a disease with protean manifestations which is becoming of greater interest to the pediatric otolaryngologist. We discuss diagnosis of this entity.
