Abstract
Many evidences show that bronchial asthma may be triggered or enhanced by gastroesophageal reflux (GER) even if standardized methods to detect this particular syndrome defined as “gastric asthma” are not available. The Bernstein test suitably modified was performed in 6 adult asthmatic outpatients when they were symptom-free. These subjects were also suffering from recurrent epigastric pain. The patients resulted positive to ultranebulized fog bronchial challenge and all had a moderate- severe alteration of the competency of the lower esophageal sphincter, shown by endoscopy. Functional lung parameters were significantly reduced after esophageal acidification when they were compared to basal values. Is the linkage between GER and asthma important in clinical practice? In asthmatic patients GER represents an important trigger for broncoconstriction through a vagal mediated reflex. The modified Bernstein test represents a reproducible method and may be well used to identify “gastric asthma”, particularly when this picture is “silent”, less evident, or it is not rightly considered. Moreover, its recognition is very relevant to therapeutic problems, also when it is in a subclinical stage. In fact, many “excellent” drugs used for bronchial asthma treatment may have undesirable effects for the gastric tract causing abnormalities such as GER that is so damaging in the development of “gastric asthma”.

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
Prokinetic agents are effective not only for disease of the gastrointestinal (GI) tract but also for those external to the GI tract such as the central nervous system, and the respiratory, urologic, and metabolic organs. This article reviews the effectiveness of prokinetic agents against diseases external to the GI tract. Studies were identified by computerized and manual searches of the available literature. A Medline search was performed (1975-July, 2008) using the following medical subject headings: prokinetic agent, metoclopramide, domperidone, trimebutine, cisapride, itopride, mosapride, tegaserod, and human. The identified diseases for which prokinetic agents may be effective are various: bronchial asthma, chronic cough, hiccup, spontaneous bacterial peritonitis, cholelithiasis, diabetes mellitus, acute migraine, Parkinson's disease, anorexia nervosa, Tourette's disorder, urologic sequelae of spinal cord injury and of radical hysterectomy for cervical cancer, laryngeal dysfunction and so on. These agents are also useful for prevention of aspiration pneumonia during anesthesia, and in tube-fed patients. Prokinetic agents should be a valuable addition to our currently limited pharmacological armamentarium not only for functional bowel disease, but also for diseases external to the GI tract.

Abstract
STUDY OBJECTIVES To investigate whether distal esophageal acidification occurs during sleep in patients suspected of sleep-disordered breathing, and whether such acidification is related to respiratory abnormalities. DESIGN AND PATIENTS Fourteen middle-aged, snoring men all complaining of daytime sleepiness and suspected of having obstructive sleep apnea. SETTING Sleep laboratory, Pulmonary Department, Landspitali University Hospital, Reykjavik, Iceland. MEASUREMENTS AND RESULTS Each patient underwent full nocturnal polysomnography testing, which included continuous monitoring of esophageal pressure (Pes) and pH. We identified all pH events, which were defined as a reduction in esophageal pH of >/= 1.0. During each pH event, the respiratory recordings where examined for the presence of apneas or hypopneas, and Pes was recorded. The data were analyzed to determine the possible relationships between pH events and respiratory events, and between changes in pH and changes in Pes. We found that there were more respiratory events than pH events. The mean (+/- SD) number of apneas and hypopneas per hour of sleep was 33 +/- 22, whereas the mean number of pH events per hour of sleep was 7 +/- 6. Overall, 81% of all pH events were associated with respiratory events. Correlation analysis did not reveal any significant relationship between pH events and the magnitude of Pes or apnea-hypopnea index. CONCLUSIONS Episodes of esophageal acidification are common in patients with sleep apnea, and are usually associated with respiratory and pressure events. However, changes in pH were independent of the magnitude of the Pes.

Abstract
The infant or child presenting to the physician's office with persistent or recurrent wheezing during the first two year's of life poses a diagnostic dilemma. A careful medical history should document risk factors for persistent wheezing, including maternal smoking, feeding practices, environmental history, and family history of asthma or cystic fibrosis (CF). A suggested diagnostic approach to the causes of infantile wheezing is outlined. A chest radiograph is non-specific, but may suggest a congenital airway anomaly. Infant pulmonary function testing (IPFT) can help differentiate between central airflow (intrathoracic, extrathoracic, or fixed) and peripheral airflow obstruction. The infant with either intrathoracic, extrathoracic, or fixed airflow obstruction on the PFT may benefit from flexible fiberoptic bronchoscopy. The infant with either an intrathoracic or fixed airway obstruction should undergo an upper gastrointestinal (UGI) series to evaluate the anatomy for extrinsic tracheal compression. The response to treatment with anti-inflammatory therapy may suggest an inflammatory disease such as asthma or CF. The infant with peripheral airflow obstruction and a good response to bronchodilators (> or =25%) using the forced exhalation technique is given the diagnosis of infantile asthma. The infant with peripheral airflow obstruction and no response to bronchodilators should be evaluated further for possible gastroesophageal reflux disease (GERD), and for other causes, which are associated with wheezing symptoms.

Abstract
Since the early 1960s, many studies have been published that consider the possible relationship between gastro-oesophageal (acid) reflux (GORD) and various other complaints, including dental erosions, ear, nose and throat problems, chronic cough and asthma. Although a high coincidence of GORD and these supra-oesophageal complaints have been noted, there is no consensus on the pathophysiology and management of such complications. In this article we review the literature published between 1966 and 2000 on this subject. We also analyse the available information on the incidence, pathophysiological mechanisms, diagnostic approach and therapeutic options in the various subgroups of disorders.

Abstract
A variety of drugs are used in the neonatal nursery for the management of feeding intolerance, gastroesophageal reflux, and acid-related disease. Although the pharmacokinetics of some of these drugs have been described in infants and older children, further data are needed, particularly for preterm infants. No data are available characterizing the disposition of the proton pump inhibitors, which will likely be used in infants with refractory, acid-related disease. Further data are also needed to characterize fully the pharmacodynamics, or efficacy, of many of the commonly used drugs.

Abstract
As gastro-oesophageal reflux disease (GORD) in infants and children is a motility disorder which differs in pathophysiology and clinical course from GORD in adults, prokinetics should be considered the drug of choice in certain circumstances. Indeed, cisapride may result in improvement of feeding tolerance in premature infants. Cisapride has a better tolerability profile than a 'wait-and-see-if-improvement-comes-spontaneously' policy or the other therapeutic options available. A careful and critical review of published data suggests that cisapride may have a QTc-prolonging effect. However, provided the precautions for cisapride administration are followed, the QTc-prolonging effect remains consistently without clinically relevant adverse effects. Correct dosage and avoidance of concurrent treatment with macrolides and/or azoles are the most relevant tolerability recommendations in children. Although there is a need for a prokinetic with better efficacy, cisapride is currently the prokinetic with the best benefit-to-risk ratio available. Thus, withdrawal of cisapride would result in a significantly increased risk for severe complications in infants and children with GORD or other gastrointestinal motility disorders such as chronic intestinal pseudo-obstruction, gastroparesis and feed intolerance in premature infants.

Abstract
BACKGROUND Major concerns about serious cardiac side effects underlie the recent decision by the FDA and Janssen Pharmaceutica (Titusville, NJ) to make cisapride available only through a limited access program. Concerns have grown despite the fact that most instances of prolonged QTc and other ventricular arrhythmias occurred while the drug was used concomitantly with contraindicated drugs. This study sought to analyze electrocardiograms (ECGs) from a multicenter pediatric study and to identify abnormalities in QTc interval associated with cisapride use. METHODS Children between 6 months and 4 years of age were enrolled if they manifested symptoms of gastroesophageal reflux not responding to medical therapy for at least 6 weeks. In 49 subjects, ECGs obtained before and after randomization to receive 0.2 mg/kg dose three times daily or placebo were reviewed independently and blindly by two pediatric cardiologists. Placebo and active drug groups were compared for QTc and for change in QTc from baseline values after 3 to 8 weeks of treatment. RESULTS Mean QTc among patients taking the drug was 408+/-18 ms. None was higher than 450 ms. Change between baseline and subsequent QTc at 3 to 8 weeks of treatment was 2+/-20 ms. CONCLUSIONS In our study group of children without underlying cardiac disease or electrolyte imbalance, cisapride was found to have no significant effect on cardiac electrical function compared with placebo. These results are consistent with the drug's record of exceedingly infrequent cardiac events. Because the availability of this prokinetic is threatened, its safety and the safety and efficacy of alternative treatment options (including surgery) should be studied further.

A suggested diagnostic approach to the causes of infantile wheezing is outlined. OBJECTIVES 1. To review the physiologic considerations of the infant's airways that predispose to wheezing. 2. To discuss the key physical findings, family history, and risk factors associated with wheezing in infants. 3. To develop a rational approach to the differential diagnosis and management of infantile wheezing. DATA SOURCES The MEDLINE database as well as our clinical experience pertaining to infantile wheezing. CONCLUSIONS This review discusses the diagnostic evaluation and treatment of the wheezing infant. We suggest that infant pulmonary function testing may be used as one diagnostic aid in the workup of the wheezing infant.

Abstract
Gastro-oesophageal reflux (GOR) has been identified as a possible cause of SIDS. Several features of GOR unique to infants presenting with apparent life-threatening events (ALTEs) have led to its 'pathogenic' definition. One is that the life-threatening apnoea itself is initiated by GOR, another is that the ALTE relates to prolonged reflux during sleep, in a vulnerable sleep-state, and finally that the ALTE relates to excessive quantities of GOR. The presumption of GOR 'pathology' as a cause of SIDS however, is questionable in these susceptible infants for three reasons: firstly, GOR is physiological and occurs in most infants; secondly, there is no general consensus on what constitutes normal physiological reflux, and thirdly, variation in the recording technique and methods of data analysis and interpretation may account for the differences between study groups. It seems likely therefore if GOR is implicated in SIDS, additional factors are involved. Under certain circumstances, physiological GOR may trigger life-threatening apnoea in apparently healthy infants, that leads to SIDS. One mechanism that could explain such a death is reflex apnoea by stimulation of laryngeal chemoreceptors (LCR) during sleep. The conditions under which this could be fatal are the occurrence of gastric contents refluxed to the level of the pharynx during sleep, in the young infant who has depressed swallowing and arousal. That is, the occurrence of GOR to the level of the pharynx during sleep, an infrequent event that is usually innocuous, could be converted to a fatal event if swallowing is impaired and arousal depressed, by a variety of mediating factors such as prone sleeping, prematurity, sedatives, seizures or upper respiratory tract infections. The identification of LCR responses, particularly in prone sleeping and premature infants provide further evidence that this mechanism may be implicated in the aetiology of SIDS in apparently healthy infants.

Abstract
Gastro-oesophageal reflux is a frequent, aspecific phenomenon in infants and children. The recommended approach in infants with uncomplicated regurgitation consists of reassurance of the parents and, if this fails, dietary recommendations in formula-fed infants. If, despite these efforts, symptoms persist, administration of prokinetics, such as cisapride, is recommended prior to investigations such as oesophageal pH monitoring. Oesophageal pH monitoring is also recommended to document gastro-oesophageal reflux disease in children with unusual presentations such as chronic respiratory disease. Today, cisapride is the drug of choice because it has the best efficacy and safety profile. In infants and children presenting with symptoms suggesting oesophagitis, endoscopy of the upper gastrointestinal tract is recommended. If there is severe oesophagitis, acid suppression with histamine H2-receptor antagonists or proton pump inhibitors in combination with prokinetics, are recommended. In life-threatening situations, or in patients that are resistant to or dependent on acid-suppressive medication, a surgical procedure such as laparascopic Nissen procedure should be considered.

Abstract
Therapy of supraesophageal manifestations of gastroesophageal reflux disease (GERD) in infants and children nearly always includes "lifestyle modifications" (conservative or nonpharmacologic therapy). Depending on the severity of the GERD manifestation, pharmacotherapy is often added. Although data to support the practice are not abundant, it is rational to begin with prokinetic pharmacotherapy and to add acid suppression if pathologic effects of acid contact with the esophagus or airway are suspected. Pathologic effects of acid produce most forms of supraesophageal GERD; the exception is infantile regurgitation, the most common example of supraesophageal GERD, which is often unaccompanied by either esophagitis or evidence of acid entry into the airway. Currently, fundoplication is rarely required for pediatric GERD, but the supraesophageal complications of GERD are more common indications for this surgery than the esophageal complications in children. Other management options for supraesophageal symptoms in children include delivery of nutrients by tube feeding slowly and continuously into the stomach or, better, small intestine. Short-term or trial tube feeding uses a transnasal tube, for example, for nasojejunal feeding; longer-term tube feeding is simplified by a gastrostomy, which can be placed relatively noninvasively using endoscopy or fluoroscopy.

Abstract
AIMS To investigate the pharmacokinetics of enterally administered cisapride suspension in young infants being treated for gastro-oesophageal reflux disease. METHODS Plasma cisapride concentrations in 49 subjects (weight: 825-5010 g; n=108 samples, median two per patient; concentration: 14.8-170 ng ml-1 ) were fitted to a one-compartment model with first-order absorption and elimination in the NONMEM program using a logarithmic transformation of the observed and predicted concentrations. Fitting was achieved using the first order conditional estimation (FOCE) method with interaction between the interpatient and intrapatient variabilities. The interpatient variance of clearance (CL/F ) and volume of distribution (V /F ) and their covariance were estimated using an exponential error model. Intrapatient (residual) variance was estimated using an additive model. RESULTS The clearance of cisapride was shown to be linearly related to current body weight, slope: 0.538. The typical population values of CL/F, V /F and Ka (absorption rate constant) were 0.538 l h-1 kg-1, 21.9 l, and 2.58 h-1, respectively. The population coefficients of variation (CV%) for CL/F and V/F were 34.4% and 84.3%, respectively. The squared coefficient of correlation between random effects for CL/F and V /F was 0.45. The intrapatient variance was 0.15. V /F and Ka were not influenced significantly by any patient characteristic. CONCLUSIONS Cisapride pharmacokinetics in infants with reflux disease were satisfactorily described by a one-compartment model. Current weight should be taken into account when calculating maintenance cisapride doses in these infants.

Abstract
Bronchial asthma is a disease that has been recognized for centuries, which is influenced mainly by genetic and environmental factors. The current interest of bronchial asthma is focused to ascertain the causes and the mechanisms that induce bronchoconstriction. Recently, abnormalities of the esophageal and gastric tracts have become important related areas for research. In predisposed individuals, these abnormalities can trigger or worsen the particular syndrome better known as "gastric asthma." In bronchial asthma the disorder of gastroesophageal reflux (GER) occurs more often than would be expected by chance. The neurogenic mechanism is considered to be the main cause of bronchoconstriction. The diagnosis of gastric asthma is particularly difficult and it should be considered also when GER is less evident or not recognized. In asthmatic patients the recognition of gastric abnormalities is very relevant for therapeutic problems also when GER is in a subclinical stage. In fact, many drugs used in the treatment of bronchial asthma can promote or enhance GER and subsequently they can worsen the symptoms of gastric asthma.

Abstract
AIM To determine the effect of cisapride on gastrointestinal motility in preterm infants. METHODS Cisapride (0.2 mg/kg, 8 hourly ) or placebo was given first for seven days in a double blind randomised crossover study of 10 preterm infants. Gastrointestinal motility was assessed on day 3 of each treatment. The half gastric emptying time (GET1/2) was determined by using ultrasonography to measure the decrease in the gastric antral cross sectional area after a feed. The whole gastrointestinal transit time (WGTT) was assessed by timing the transit of carmine red through the gut. Treatments were compared using the Wilcoxon matched pairs signed ranks test. RESULTS Median (range) birthweight was 1200 (620, 1450) g and postconceptional age 33 (29, 34) weeks at recruitment. GET1/2 was significantly longer during cisapride treatment than during placebo; the median of the differences (95% confidence interval) was 19.2 (11, 30 minutes, p=0.008). WGTT was also longer during cisapride treatment, but the difference was not significant; the median of the differences was 11(-18, 52 hours, p=0.1). CONCLUSIONS Cisapride delays gastric emptying and may delay WGTT in preterm infants. Its use to promote gastrointestinal motility in this group cannot be recommended.

Abstract
The diagnosis of gastro-oesophageal reflux (GOR) is of great interest for paediatric gastroenterologists. pH monitoring is the commonly used procedure for GOR diagnosis but a major amount of postprandial GOR is missed due to the mostly non-acidic gastric contents in infants. The multiple intraluminal impedance technique is based on the recording of the impedance changes during bolus transport inside the oesophagus. It is the first method which allows the pH-independent, long-term registration of GOR. The use of the impedance technology in clinical practice has been limited so far by the time-consuming, visual evaluation of the impedance traces. The new approach of a semi-automatic analysis of the impedance measurements allows the automated detection of reflux patterns. It is based on event marking and an optimised feature description of the impedance traces combined with a fuzzy system for pattern recognition. The classifier is developed and tested on 50 investigations in infants. Compared to the comprehensive, multiple visual evaluation the achieved precision is 75% sensitivity and 48% positive prediction. In comparison to a single visual evaluation the analysis of the automatically proposed patterns corresponds to a 96% reduction of the evaluation time with no loss of precision. Thus the applicability of the impedance technology is enhanced significantly. A combined measurement of pH and impedance gives evidence about the occurrence of GOR, its pH and the acidic exposure of the oesophagus.

Abstract
Pathological processes and disease entities in the upper gastrointestinal (GI) tract, specifically those of the oesophagus and the stomach in infancy, have received a disproportionately small amount of attention until recently when appreciation of their pathophysiology and concordant importance in terms of symptomatology has been highlighted. This is probably a phenomenon secondary to improved diagnostic yield from the recent technical advances in areas such as infant endoscopy and a shift in opinion regarding the pathophysiological origin of ubiquitous symptoms of infancy such as feeding disorders, colic and irritability. In addition, the apparently complex interactions of various aetiological factors such as pH-independent gastro-oesophageal reflux (GOR), cow's milk protein intolerance (CMPI), Helicobacter pylori gastritis and upper GI motor disorders have in the past 1-2 years become underlined in terms of aetiopathogenesis and have radically changed thinking regarding diagnosis and therapy of infants with apparent upper-GI-associated symptoms. The contribution to comprehension of infant upper GI disorders of inflammatory paradigms and ontogeny of the upper GI tract is also a recent area worthy of mention. The recent advances in all of these areas and their contribution to the understanding, and subsequent diagnosis and therapy, of upper GI symptoms and their explanation by way of aetiopathogenesis will be explored in this chapter.

Abstract
Regurgitation in infants is a common problem. Recent issues, such as the increased risk of sudden infant death in the prone sleeping position, the finding of persisting occult gastro-oesophageal reflux with feed thickeners, and the increasing awareness of the cost-benefit ratio of medications may challenge the currently recommended management approach. A round table was organized to elaborate on the impact of (i) the pro supine sleeping campaigns in relation to sudden infant death and (ii) advancement in medical treatment on therapeutic strategies in regurgitating infants. The participants were opinion leaders from Europe and North America (Belgium, Canada, France, UK, Italy, Switzerland and The Netherlands). The importance of parental reassurance is stressed. As a consequence of the supine sleeping campaigns aiming to decrease the incidence of sudden infant death syndrome, the "prone elevated sleeping position" is no longer advised as a first-line therapeutic approach, although it is still recommended in "complicated reflux". It is emphasized that milk thickeners are an adequate therapeutic tool for regurgitation, but not in reflux disease. According to the literature, the efficacy of (alginate )antacids, although very popular in some countries, is questionable. These recommendations will be of interest to first-line paediatricians, since about 40% of their patients, according to the literature, present because of regurgitation.

Abstract
Gastro-oesophageal reflux (GOR) has been implicated in such clinical phenomena as aspiration pneumonia, bronchospasm or wheezing, apnea, stridor, and hoarseness. Various tests have been used as an aid to diagnosing patients with chronic respiratory disease where GOR is a causal factor. Different forms of conservative treatment have been tried for GOR, including cisapride. Several studies have evaluated its effect on the pH profile and respiratory symptoms in patients with chronic respiratory disease and have demonstrated improvement of nocturnal wheezing, cough, and irritability. Our experience with cisapride is positive in children with GOR. Patients refractory to medical treatment have been surgically treated with good results.

Abstract
OBJECTIVE To summarize the pharmacology, pharmacokinetics, efficacy, and safety of cisapride, and to evaluate its potential therapeutic role. DATA SOURCES A computerized search of the MEDLINE database was used to identify English-language publications of cisapride data in humans. The MEDLINE search was supplemented by review article bibliographies. There was no attempt to limit the search to a specific gastrointestinal motility disorder. STUDY SELECTION The MEDLINE search alone identified 165 citations. Because of the volume of available human cisapride data, the focus of the efficacy section is on complete published reports of controlled clinical studies. Abstracts and uncontrolled data are discussed only when other information is unavailable to address important aspects. DATA EXTRACTION Information regarding study design, study population, results, and safety was recorded from each publication. The placebo response to gastrointestinal complaints in patients with motility disorders is high. Therefore, objective evidence of improvement was emphasized when documentation was available. DATA SYNTHESIS Cisapride stimulates the motility of smooth muscle lining the esophagus, stomach, small intestine, and colon, and increases the tone of gut sphincters in vitro and in vivo. In controlled investigations, cisapride was superior to placebo in relieving symptoms associated with reflux esophagitis, nonulcer dyspepsia, and gastroparesis. Similar symptom and healing effects were observed with cisapride and histamine (H)2-antagonists in reflux esophagitis. Cisapride was either equal to or superior to metoclopramide in relieving reflux symptoms. However, metoclopramide was associated with significantly more central nervous system adverse effects. Cisapride was well tolerated, with adverse effects limited primarily to the gastrointestinal tract. CONCLUSIONS Cisapride represents an attractive alternative to metoclopramide for the treatment of a variety of motility disorders. Because it addresses a primary underlying cause of reflux esophagitis, cisapride may also prove to be an effective alternative to acid suppressants in the management of this disorder.

Abstract
We studied sleeping infants in order to investigate whether a temporal relation exists between acid reflux extending to the proximal portion of the oesophagus and cardiorespiratory events. One hundred infants with occasional regurgitations were studied: 50 infants admitted after an apparently life-threatening event (ALTE) that occurred during sleep and that remained unexplained despite medical investigation, and 50 asymptomatic infants (non-ALTE). The infants had a median age of 8 weeks (range 4-26 weeks); 54 were boys. In each child a pH probe was placed in the proximal portion of the thoracic oesophagus, under radiological control. Polygraphic monitoring of state of alertness, cardiorespiratory activity, and proximal oesophageal pH changes was conducted continuously during 1 night. The data were analysed blind. In 80 infants a total of 186 decreases in oesophageal pH below 4 units were seen; 37% occurred during wakefulness, and 40% during rapid eye movement (REM) sleep. A total of 7029 central and 61 obstructive apnoeas were monitored, mainly during REM sleep. Within 5 min before, and 5 min after the drops in pH, there was no difference in the number, or the duration of bradycardia, central, mixed, or obstructive apnoea. The infants with an ALTE could not be differentiated from the non-ALTE infants for any of the variables studied. It is concluded that spontaneous acid refluxes extending to the proximal portion of the oesophagus during sleep are usually not temporally related with the development of apnoeas or bradycardias.
