Long-term effects of fundoplication in children with chronic airway diseases. J Pediatr Surg 2015; 50:206-10. [PMID: 25598124 DOI: 10.1016/j.jpedsurg.2014.09.079] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2014] [Revised: 09/05/2014] [Accepted: 09/09/2014] [Indexed: 12/12/2022]
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
OBJECTIVE To develop a North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) and European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) international consensus on the diagnosis and management of gastroesophageal reflux and gastroesophageal reflux disease in the pediatric population. METHODS An international panel of 9 pediatric gastroenterologists and 2 epidemiologists were selected by both societies, which developed these guidelines based on the Delphi principle. Statements were based on systematic literature searches using the best-available evidence from PubMed, Cumulative Index to Nursing and Allied Health Literature, and bibliographies. The committee convened in face-to-face meetings 3 times. Consensus was achieved for all recommendations through nominal group technique, a structured, quantitative method. Articles were evaluated using the Oxford Centre for Evidence-based Medicine Levels of Evidence. Using the Oxford Grades of Recommendation, the quality of evidence of each of the recommendations made by the committee was determined and is summarized in appendices. RESULTS More than 600 articles were reviewed for this work. The document provides evidence-based guidelines for the diagnosis and management of gastroesophageal reflux and gastroesophageal reflux disease in the pediatric population. CONCLUSIONS This document is intended to be used in daily practice for the development of future clinical practice guidelines and as a basis for clinical trials.

Abstract
A global evidence-based consensus has defined gastroesophageal reflux disease (GERD) as 'a condition, which develops when the reflux of stomach contents causes troublesome symptoms and/or complications.' The manifestations of GERD can be divided into esophageal and extraesophageal syndromes, and include vomiting, poor weight gain, dysphagia, abdominal or substernal/retrosternal pain, esophagitis and respiratory disorders. The extraesophageal syndromes have been divided into established and proposed associations: established would include cough, laryngitis, asthma and dental erosion ascribable to reflux, whereas proposed associations would include pharyngitis, sinusitis, idiopathic pulmonary fibrosis and recurrent otitis media. Uninvestigated patients with esophageal symptoms without evidence of esophageal injury would be considered to have asymptomatic esophageal syndromes, whereas those with demonstrable injury are considered to have esophageal syndromes with esophageal injury. Therefore, this allows symptoms to define the disease but permits further characterization if mucosal injury is found. Within the syndromes with associated injury are reflux esophagitis, stricture, Barrett's esophagitis and adenocarcinoma. This review will address definitions of GER and GERD-associated symptoms and treatment options.

Abstract
AIM To investigate aspiration risks associated with bronchiolitis in infants using the lipid-laden macrophage index (LLMI) from laryngeal lavages. METHODS Laryngeal lavages from 29 infants with acute bronchiolitis caused by respiratory syncytial virus were evaluated (acute stage). Repeated studies were then performed at 3-4 weeks after the initial study (remission stage). Lavage cell counts and differentials were determined. The amount of lipid per single macrophage was evaluated and the LLMI was determined by evaluating 100 cells. In addition, 24-h pH monitoring (pHm) was performed in 16 patients. RESULTS The LLMIs in the acute stage were significantly higher than those in the remission stage (p < 0.05). The neutrophil percentage of the laryngeal lavage correlated significantly with the LLMI (r = 0.707, p < 0.0001) during the acute stage of bronchiolitis. When patients were divided into pHm-positive (n = 5) and pHm-negative (n = 11) subgroups, a significant decrease in LLMI between acute and remission stages was noted among the pHm-positive (p < 0.01) subgroup, but not in the pHm-negative subgroup. CONCLUSION These findings suggest that there is a transient increased LLMI in patients with bronchiolitis, which could be caused by gastroesophageal reflux.

Abstract
Gastro-esophageal reflux (GER) is a physiological process characterized by the involuntary passage of gastric contents into the lower esophagus not induced by noxious stimuli. It represents a common condition in preterm infants and may occur in healthy neonates. The phenomenon is only considered as GER disease when it causes the patient to be symptomatic or results in pathological complications. Fundoplication is recommended in symptomatic neonates and infants with GER that does not respond to medical treatment. The presence of respiratory symptoms related to GER is the primary indication for fundoplication in this selected population. The Nissen fundoplication is the antireflux procedure of choice and the experience concerning other procedures, including laparoscopic techniques, is limited in this age group. The best results are achieved in newborn infants with isolated GER, as the recurrence rate of GER in infants with associated anomalies is high. Further studies are necessary to evaluate the benefit of laparoscopic fundoplication in this age group.

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
About 50% of children with chronic respiratory diseases (RD) have "silent" gastroesophageal reflux (GER). Our purpose was to evaluate the possibility that RD in patients with GER reflects the presence of more severe acid reflux. We compared the severity of parameters from pH studies in children with chronic RD and "silent" GER, to children with signs of symptomatic gastrointestinal (GI) GER with and without RD. This study included 236 children (aged 1 month to 15 years) with abnormal 24-hr pH monitoring among 718 patients studied for suspected diagnosis of GER. Patients were divided into three groups. Group 1 consisted of children with chronic RD but without any GI symptoms of GER. Group 2 was comprised of children with symptomatic GI presentation of GER such as regurgitation, vomiting, heartburn, and failure to thrive, but without any signs or symptoms of RD. Group 3 included children with prevalent RD and concomitant signs of symptomatic GER. Patients with predominant GI manifestations (group 2) had a significantly higher fraction of time with pH <4 (P < 0.01), total time value of pH <4 (P < 0.05), and longest episode with pH <4 (P < 0.05). Esophageal clearance was significantly longer in group 1 patients than in the other two groups (P < 0.05). Patients with mixed disease (group 3) were similar to patients in group 2. Patients with GI symptoms had significantly worse scores for all parameters evaluated except esophageal clearance score, compared to patients without GI symptoms. Longer esophageal clearance was the only parameter associated with respiratory signs in patients with respiratory symptoms compared to those without. In conclusion, the presence of RD in pediatric patients with silent GER is related to longer esophageal clearance, but is not related to severity of reflux.

Abstract
OBJECTIVES The associations between gastro-oesophageal reflux (GOR), chronic respiratory symptoms and gastrointestinal complications have been well described. The aim of this study was to compare the characteristics of children in whom the main indication for fundoplication was respiratory disease with children who had gastrointestinal indications for surgery. METHODS A retrospective review of 79 children who underwent fundoplication between January 1995 and December 1999. RESULTS Forty-nine of the children (62%) had a respiratory indication for fundoplication. Children with neurological impairment tended to have a respiratory rather than a gastrointestinal indication for surgery. Congenital anomalies were present in 47%. Fundoplication in older children was more likely to be for a gastrointestinal indication. Children with neurological impairment were more likely to have a gastrostomy compared to children with normal neurological status (P < 0.01). Children with a respiratory indication were more likely to have three or more diagnostic investigations (P < 0.001). Ninety-two per cent of children with a respiratory indication and 90% with a gastrointestinal indication for fundoplication had at least one positive test for GOR (barium meal or 24-h oesophageal pH monitoring). Oesophagoscopy showed reflux oesophagitis in 46/61. Eighty-five per cent of the children had complete resolution of their symptoms after fundoplication. CONCLUSIONS Neurological comorbidity was common in children who had surgery for gastro-oesophageal reflux disease, whether for gastrointestinal or respiratory indications. The majority of fundoplications were performed for respiratory indications.

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
Gastroesophageal reflux (GER), defined as passage of gastric contents into the esophagus, and GER disease (GERD), defined as symptoms or complications of GER, are common pediatric problems encountered by both primary and specialty medical providers. Clinical manifestations of GERD in children include vomiting, poor weight gain, dysphagia, abdominal or substernal pain, esophagitis and respiratory disorders. The GER Guideline Committee of the North American Society for Pediatric Gastroenterology and Nutrition has formulated a clinical practice guideline for the management of pediatric GER. The GER Guideline Committee, consisting of a primary care pediatrician, two clinical epidemiologists (who also practice primary care pediatrics) and five pediatric gastroenterologists, based its recommendations on an integration of a comprehensive and systematic review of the medical literature combined with expert opinion. Consensus was achieved through Nominal Group Technique, a structured quantitative method. The Committee examined the value of diagnostic tests and treatment modalities commonly used for the management of GERD, and how those interventions can be applied to clinical situations in the infant and older child. The guideline provides recommendations for management by the primary care provider, including evaluation, initial treatment, follow-up management and indications for consultation by a specialist. The guideline also provides recommendations for management by the pediatric gastroenterologist. This document represents the official recommendations of the North American Society for Pediatric Gastroenterology and Nutrition on the evaluation and treatment of gastroesophageal reflux in infants and children. The American Academy of Pediatrics has also endorsed these recommendations. The recommendations are summarized in a synopsis within the article. This review and recommendations are a general guideline and are not intended as a substitute for clinical judgment or as a protocol for the management of all patients with this problem.

Abstract
BACKGROUND & AIMS The potential association between gastroesophageal reflux disease (GERD) and extraesophageal manifestations remains unknown in children without neurological defects. We conducted a large case-control study to examine the association between GERD and several upper and lower respiratory disorders in these children. METHODS We identified all patients between 2 and 18 years of age with GERD who were seen at Texas Children's Hospital between 1996 and 2000. Patients seen during the same time period without GERD were randomly selected as controls (4:1 ratio). Patients with mental retardation, cerebral palsy, or congenital esophageal anomalies were excluded. We compared the presence of several predefined upper and lower respiratory disorders in cases and controls. RESULTS We identified 1980 patients with GERD and 7920 controls without GERD. Cases and controls were without neurological deficits or congenital esophageal anomalies. Cases were older than controls (9.2 years +/- 4.6 vs. 8.6 +/- 4.9, P < 0.0001), and were more likely to be female (51.2% vs. 47.2%, P = 0.0028) and white (60.2% vs. 41.2%, P < 0.0001). Compared with controls in univariate analyses, cases with GERD had more sinusitis (4.2% vs. 1.4%, P < 0.0001), laryngitis (0.7% vs. 0.2%), asthma (13.2% vs. 6.8%, P < 0.0001), pneumonia (6.3% vs. 2.3%, P < 0.0001), and bronchiectasis (1.0% vs. 0.1%, P < 0.0001). However, otitis media was less common in cases than controls (2.1% vs. 4.6%, P < 0.0001). After adjusting for differences in age, gender, and ethnicity in the regression analyses, GERD remained a significant risk factor for sinusitis (adjusted odds ratio [OR], 2.3; 95% confidence intervals [CI], 1.7-3.2; P < 0.0001), laryngitis (OR, 2.6; CI, 1.2-5.6; P = 0.0228), asthma (OR, 1.9; CI, 1.6-2.3; P < 0.0001), pneumonia (OR, 2.3; CI, 1.8-2.9; P < 0.0001), and bronchiectasis (OR, 2.3; CI, 1.1-4.6; P = 0.0193). CONCLUSIONS GERD in children without neurological defects is associated with a several-fold increase in the risk of sinusitis, laryngitis, asthma, pneumonia, and bronchiectasis. Further studies are needed to examine whether a cause-effect relationship exists between GERD and these disorders in children.

Abstract
OBJECTIVE We conducted a retrospective study to determine the relationship between gastroesophageal reflux (GER) and large airways malacia in infancy. METHODS One hundred sixteen children referred for chronic respiratory problems who were between the ages of 3 and 28 months were investigated. All of them underwent flexible bronchoscopy and chest radiography. Eighteen children had laryngomalacia, 13 had tracheomalacia, and 23 had combined laryngotracheomalacia. During bronchoscopy, BAL was performed. An analysis of macrophages in the BAL fluid for lipid content was performed. Fifty-four children with laryngomalacia and tracheomalacia constituted the study group, and 62 children were in the control group. Reflux studies were obtained for 40 children from the study group and 41 from the control group. RESULTS In the study group, 28 children (70%) had GER documented by reflux studies compared with 16 children (39%) in the control group (p < 0.01). In the control group, GER was found mainly among those with recurrent bilateral pneumonia. The lipid-laden macrophage score was correlated with the documented GER. CONCLUSION GER is prevalent among infants with large airways malacia, and treatment of this group with antireflux therapy should be considered.

Abstract
CONTEXT Gastroesophageal reflux (GER) has not previously been widely regarded as a hereditary disease. A few reports have suggested, however, that a genetic component may contribute to the incidence of GER, especially in its severe or chronic forms. OBJECTIVE To identify a genetic locus that cosegregates with a severe pediatric GER phenotype in families with multiple affected members. DESIGN A genome-wide scan of families affected by severe pediatric GER using polymorphic microsatellite markers spaced at an average of 8 centimorgans (cM), followed by haplotyping and by pairwise and multipoint linkage analyses. SETTING General US community, with research performed in a university tertiary care hospital. SUBJECTS Affected and unaffected family members from 5 families having multiple individuals affected by severe pediatric GER, identified through a patient support group. MAIN OUTCOME MEASURES Determination of inheritance patterns and linkage of a genetic locus with the severe pediatric GER phenotype by logarithm-of-odds (lod) score analysis, considering a lod score of 3 or greater as evidence of linkage. RESULTS In these families, severe pediatric GER followed an autosomal dominant hereditary pattern with high penetrance. A gene for severe pediatric GER was mapped to a 13-cM region on chromosome 13q between microsatellite markers D13S171 and D13S263. A maximum multifamily 2-point lod score of 5.58 and a maximum multifamily multipoint lod score of 7.15 were obtained for marker D13S1253 at map position 35 cM when presumptively affected persons were modeled as unknown (a maximum multipoint score of 4.88 was obtained when presumptively affected persons were modeled as unaffected). CONCLUSION These data suggest that a gene for severe pediatric GER maps to chromosome 13q14. JAMA. 2000;284:325-334

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
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
Lipid-laden macrophages (LLM) in tracheal aspirates are reported to be pathognomonic findings in exo- and endogenous lipoid pneumonia in adults. A pilot study was carried out to evaluate the effect of lipid infusion on the LLM index of the tracheal aspirates from ventilated neonates. All intubated infants were eligible for the study. Infants receiving parenteral nutrition had intravenous (IV) lipid introduced by 4-7 days of age; most samples after 7 days were from infants receiving IV lipid. Four infants received minimal gastric feeding; none had evidence of aspiration pneumonia. Tracheal aspirates from 28 infants were analyzed for the LLM index. Alveolar macrophages were graded 0-4 in direct relation to the amount of lipid per cell. One hundred macrophages were graded; the maximum possible LLM index was 400. Two hundred forty-five of 387 tracheal aspirate samples were acceptable for analysis. LLM indices increased during the first week after birth; the mean LLM index then continued in the same range, but with a wide distribution of individual values. The mean LLM index from infants receiving an IV lipid infusion during days 4-7 was 87.9 (SD = 44.8), and was significantly higher compared to 58.7 (SD = 40.8) in infants receiving no IV lipid (P < 0. 003). Tracheal aspirates from infants with and without IV lipid infusion yielded many LLM index values >100. These observations invalidate the use of the LLM index >100 as proof of aspiration pneumonia in this group of infants.

Abstract
The aim of our study was to evaluate the success, complications, and morbidity following a modified Thal fundoplication in children with reflux-associated respiratory disease (RARD). We used a procedure consisting of retroesophageal hiatal plasty, wrapping the gastric fundus around the gastroesophageal junction 180 degrees, and fixation of the lesser curvature at the abdominal wall. Follow-up by questionnaire of 128 (77 male, 51 females) out of 196 antireflux procedures between 1992 and 1995 was achieved. Surgical therapy was considered justified whenever there was gastroesophageal reflux resulting in severe recurrent respiratory symptoms. Eleven percent of the children suffered from bronchiectasis. The diagnosis of RARD was based on a high index of suspicion, barium swallow with fluoroscopy, 24-hr two-level pH-monitoring, bronchoscopy, bronchoalveolar lavage and detection of lipid-laden alveolar macrophages, esophago-gastroscopy, and esophageal biopsy. Patients with bronchopulmonary diseases such as allergy, immunodeficiency, cystic fibrosis, primary ciliary dyskinesia, and malformation of the bronchial tree or vessels had been excluded. "Evident improvement" as a result of surgery was reported in 88%, "no change" in 10%, and a "change for the worse" in 2% of patients. Persistent mild difficulties in swallowing were observed in 11%. Paraesophageal hernia, gas-bloat syndrome, and dumping syndrome were not observed. Two children needed a second operation because of relapse. The use of emergency steroidal medication for acute respiratory distress decreased impressively (219 single doses/year before surgery vs. 30 single doses/year after surgery). The need for more than 4 times/year of antibiotic therapy before surgery was reduced from 52. 3% before to 14% after surgery. Most (90.6%) of the parents stated they would agree to have surgery done again if medically indicated. In conclusion, Thal fundoplication is sufficient, safe, and effective in the management of RARD. Complications of the procedure were minor and of little consequence to the patient.

Abstract
At present there is no test available which identifies children suffering from silent aspiration due to gastroesophageal reflux (GER). The purpose of this study was to determine whether lipid-laden alveolar macrophage (LLAM) scoring is a useful method to arrive at the diagnosis. We evaluated bronchoalveolar lavage fluid (BALF) from 68 children aged 6 months to 14 years (median 3.75 years) for the presence of lipid-laden alveolar macrophages. We compared children with chronic chest disease (CCD) and GER to healthy surgical controls without known lung disease, and to children with recurrent pneumonia without GER. By grading the amount of intracellular Sudan Red-positive material, we determined a semiquantitative lipid-laden macrophage (LLAM) score for each patient. Patients with chronic chest disease suspected to be caused by silent aspiration secondary to GER had a significantly higher LLAM score (median, 117; range, 10-956) than children with recurrent pneumonia due to other reasons (median, 29; range, 5-127; P < 0.01) and healthy controls (median, 37; range, 5-188; P < 0.01). We believe that simply observing lipid-laden macrophages is nonspecific, but quantitation of these cells is a useful method for diagnosing silent aspiration in children, especially when the score exceeds 200.

Abstract
An increased lipid content in alveolar macrophages of bronchoalveolar lavage (BAL) fluid is thought to be a useful indicator for recurrent pulmonary aspiration. To assess whether pulmonary diseases unrelated to aspiration can raise the lipid content in alveolar macrophages, we evaluated Oil-Red-O-stained smears of BAL fluid in 18 children aged 3-15 years undergoing elective surgery for nonpulmonary illnesses under general anesthesia and in 18 children aged 1-16 years who had pulmonary diseases without clinical evidence of aspiration (pneumonia, exogenous allergic alveolitis, or cystic fibrosis). A semiquantitative lipid-laden macrophage (LLM) index was determined for each patient. LLM indices in children without pulmonary disease were higher than those published for healthy adults. In children with pulmonary diseases but without evidence of aspiration, a significantly higher LLM index was observed compared to controls. The LLM indices of children with pulmonary diseases were similar to those published by other authors for children with pulmonary aspiration. We conclude that an elevated LLM index in alveolar macrophages of BAL can be found in a variety of pulmonary diseases in which there is no clinical evidence of aspiration and is therefore unlikely to be a specific parameter for silent pulmonary aspiration.

Abstract
Cough is an uncommon sign in infants. Cough may result from the presence of abnormal secretions in the airway or abnormalities of the central airways that affect the infant's ability to clear normal secretions. Tracheomalacia (TM) and gastroesophageal reflux (GER) can both cause cough in infants. Four infants whose cough began in the newborn period were diagnosed with TM and GER. Symptoms of central airway obstruction (homophonous wheeze or tracheal cough) suggested the diagnoses. In three patients, the diagnosis was made by barium esophagraphy and airway fluoroscopy. The infants responded to conservative and medical therapy for GER and to nebulized bronchodilators. Tracheomalacia and GER cause cough in infants that begins in the newborn period. The diagnosis can often be made with studies available to the primary care provider, and the conditions are often responsive to medical management.

Abstract
BACKGROUND Gastroesophageal reflux is a common condition that in infants may lead to serious complication. This study assessed the efficacy and safety of oral cisapride suspension in the treatment of children 6 weeks to 2 years old with daily regurgitant reflux. METHODS A randomized, prospective, double-blind, placebo-controlled clinical trial was conducted at three study sites. After a 1 week baseline assessment, 45 infants 6 weeks to 2 years old were randomized to a double-blind trial in which they received a 6 week course of cisapride (0.2 mg/kg q6h) or a placebo suspension. Efficacy was assessed with 24 hour esophageal pH monitoring, esophageal manometry, and esophageal biopsy before and after the treatment period. A diary of regurgitation frequency and severity was kept by the parents. Safety was assessed by adverse event monitoring and standard laboratory measurements. RESULTS Compared with placebo, cisapride significantly (p < 0.05) reduced the mean duration of upright and supine reflux episodes. Compared to baseline, cisapride significantly reduced the mean duration of the longest reflux episode, and placebo increased the mean number of reflux episodes longer than 5 minutes. Cisapride was not significantly different from placebo for the following mean measurements: percent of total time pH < 4, number of reflux episodes, lower esophageal sphincter pressure, swallow pressure, regurgitation frequency or global evaluation scores. CONCLUSIONS Cisapride is a safe, well tolerated prokinetic agent that improves the esophageal clearance of refluxed gastric acid in children under the age of 2 years.

Abstract
Gastroesophageal reflux (GER) is one of the most frequent symptomatic clinical disorders affecting the gastrointestinal tract of infants and children. During the past 2 decades, GER has been recognized more frequently because of an increased awareness of the condition and also because of the more sophisticated diagnostic techniques that have been developed for both identifying and quantifying the disorder. Gastroesophageal fundoplication is currently one of the three most common major operations performed on infants and children by pediatric surgeons in the United States. Normal gastroesophageal function is a complex mechanism that depends on effective esophageal motility, timely relaxation and contractility of the lower esophageal sphincter, the mean intraluminal pressure in the stomach, the effectiveness of contractility in emptying of the stomach, and the ease of gastric outflow. More than one of these factors are often abnormal in the same child with symptomatic GER. In addition, in patients with GER disease, and particularly in those patients with neurologic disorders, there appears to be a high prevalence of autonomic neuropathy in which esophagogastric transit and gastric emptying are frequently delayed, producing a somewhat complex foregut motility disorder. GER has a different course and prognosis depending on the age of onset. The incompetent lower esophageal sphincter mechanism present in most newborn infants combined with the increased intraabdominal pressure from crying or straining commonly becomes much less frequent as a cause of vomiting after the age of 4 months. Chalasia and rumination of infancy are self-limited and should be carefully separated from symptomatic GER, which requires treatment. The most frequent complications of recurrent GER in childhood are failure to thrive as a result of caloric deprivation and recurrent bronchitis or pneumonia caused by repeated pulmonary aspiration of gastric fluid. Children with GER disease commonly have more refluxing episodes when in the supine position, particularly during sleep. The reflux of acid into the mid or upper esophagus may stimulate vagal reflexes and produce reflex laryngospasm, bronchospasm, or both, which may accentuate the symptoms of asthma. Reflux may also be a cause of obstructive apnea in infants and possibly a cause of recurrent stridor, acute hypoxia, and even the sudden infant death syndrome. Premature infants with respiratory distress syndrome have a high incidence of GER. Esophagitis and severe dental carries are common manifestations of GER in childhood. Barrett's columnar mucosal changes in the lower esophagus are not infrequent in adolescent children with chronic GER, particularly when Heliobacter pylori is present in the gastric mucosa. Associated disorders include esophageal dysmotility, which has been recognized in approximately one third of children with severe GER. Symptomatic GER is estimated to occur in 30% to 80% of infants who have undergone repair of esophageal atresia malformations. Neurologically impaired children are at high risk for having symptomatic GER, particularly if nasogastric or gastrostomy feedings are necessary. Delayed gastric emptying (DGE) has been documented with increasing frequency in infants and children who have symptoms of GER, particularly those with neurologic disorders. DGE may also be a cause of gas bloat, gagging, and breakdown or slippage of a well-constructed gastroesophageal fundoplication. The most helpful test for diagnosing and quantifying GER in childhood is the 24-hour esophageal pH monitoring study. Miniaturized probes that are small enough to use easily in the newborn infant are available. This study is 100% accurate in diagnosing reflux when the esophageal pH is less than 4.0 for more than 5% of the total monitored time.

Abstract
This review is devoted to some controversial topics in the field of pediatric nuclear medicine. In most cases, drug sedation can be avoided and the nuclear medicine procedure can be successfully achieved simply by taking the emotional life of the child into account. Factors such as past negative experiences (painful procedures, hospitalizations), unfamiliar environment (frightening examination room), physical aggressions related to the nuclear medicine procedure (intravenous injections, cystography), and the feeling of loss of parents' protection all contribute to the child's anxiety. People in charge of pediatric procedures should be adequately trained to be aware of these factors and to create the best environmental conditions to avoid unnecessarily frightening the child. Methods for measuring renal clearance in children are numerous. It is my aim to review the different methods proposed in the literature, including the nonradioisotopic methods, the reference radioisotopic methods, the various simplified algorithms using blood samples, and the gamma-camera methods. Gastroesophageal reflux scintigraphy is a well-established procedure for the detection of gastro-esophageal reflux in children. However, despite the numerous advantages of this technique, it has not gained wide acceptance in the field of pediatric gastroenterology. This review focuses mainly on the comparison between scintigraphy and pH metry. Finally, the applications of 99m technetium-hexamethylpropylenamine brain single photon emission computer tomography in the field of pediatric neurology are still under development; this part of the review is an attempt to summarize the real contribution of this technique.

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
Pulmonary aspiration was assessed using a scintigraphic swallowing procedure in 14 dysphagics in whom penetration of the larynx had been previously diagnosed. No patient had recent evidence of aspiration pneumonia. Imaging was performed during and following ingestion of a cupful of thin liquid admixed with between 1-2 mCi of Tc-99m sulfur colloid. Follow-up scans were obtained several hours later as needed to assess airway clearance. Five of the fourteen (36%) showed penetration distal to the trachea. Seven (50%) were indeterminate for aspiration, as isotope localized to the neck could not be clearly designated as being in either airway or foodway. Two subjects had negative studies. Of patients with subtracheal penetration, (1) fractions of the ingested material which were aspirated ranged from < 1%-25%, and (2) elimination from airways was complete or near-complete by 3 hours. The presence of an immediate or delayed cough was noted but did not correlate with subtracheal aspiration. Based on the results of scintigraphy, 8 of 9 patients on some form of liquid restriction at the time of testing were allowed to ease restrictions. Five patients without prior liquid restriction were allowed to continue to drink. We propose that scintigraphy provides important data on airway penetration and clearance that is useful in the dietary management of dysphagic patients.

Abstract
Benign pulmonary diseases that have been associated with the accumulation of endogenous lipids within the alveoli, bronchioles, and interstitial tissues include endogenous lipoid pneumonia (ELP), pulmonary alveolar proteinosis (PAP), pulmonary interstitial and intra-alveolar cholesterol granulomas (PICG), various xanthomatous lesions, and malakoplakia. In ELP, fat-filled finely vacuolated macrophages fill the alveoli. In PAP, the aveoli become filled with cholesterol and periodic acid-Schiff (PAS)-positive acellular debris. In PICG, cholesterol esters are released from degenerating macrophages and, as organization occurs, the cholesterol is deposited in the form of acicular clefts within the interstitium. These morphologically distinct presentations of endogenous lipid deposition within the lung have long been thought to represent unique disease processes but several authors now postulate a possible relationship between these entities. We report here on the clinical, radiographic, and morphologic findings in eight pediatric patients with diverse primary disease processes who were subsequently found to have varying and often coexisting degrees of ELP, PAP, and PICG.

Abstract
A higher frequency (25%) of gastrooesophageal reflux (GOR) has been previously reported in patients over 5 years old with cystic fibrosis compared with controls without cystic fibrosis. It was believed that GOR was caused by the complications of cystic fibrosis. We looked for GOR in all 26 children younger than 60 months who had cystic fibrosis diagnosed. They had a classical genetic profile and the usual scattered clinical manifestations for age. GOR was confirmed in 21 (81%): 20 by abnormal pH tracings and in one on a clinical basis. After at least one month of adjusted cystic fibrosis treatment, antireflux treatment (cisapride) was given to 16 patients and variables of GOR improved dramatically. Weight gain was significant and recurrent cough and wheeze disappeared. One year later half of the patients still suffered from GOR. GOR is a major problem in the early life of those with cystic fibrosis and is not the consequence of either respiratory or gastrointestinal complications as it improves with age whereas cystic fibrosis becomes worse with age.

Eleven patients with previously documented aspiration underwent a radioisotopic swallowing study to detect and quantify airway penetration. In those subjects able to complete a rapid-acquisition phase during swallowing, no laryngotracheal penetration was seen despite previous evidence of aspiration. However, sequential static pulmonary imaging showed significant aspiration in three individuals. Attempts were made to measure the percentage of ingested material aspirated and the clearance rate from the airways. Eight patients (73%) failed to show definite evidence of aspiration on scintigrams. It is hypothesized that the lack of scintigraphic detection in previously proven aspirators was due either to interval improvement of the dysphagia or to difficult-to-detect laryngotracheal aspiration. Isotopic imaging during swallowing appears to have little utility; however, after ingestion, the technique can demonstrate more distal penetration not detected on videofluoroscopy. More studies are suggested to better define the sensitivity and specificity of scintigraphy in aspiration detection and to determine whether these techniques have prognostic value that could alter patient management.

Abstract
Gastro-oesophageal reflux in preterm infants may result in recurrent pulmonary insult due to aspiration of gastric contents, and intractable obstructive apnoea. Fundoplication is effective in controlling reflux when medical management has failed. Our experience between 1981 and 1990 was reviewed to assess the efficacy of early surgery in the management of 11 such infants. The infants had a median gestational age of 29 weeks and a median birthweight of 1032 g. Nine infants had fundoplication for recurrent aspiration pneumonitis and two for intractable apnoea. The median age at the time of surgery was 100 days and the median weight of the infants was 2640 g. Nine infants were oxygen dependent and two were still ventilated at the time of surgery. The operative procedure was well tolerated by 10 of the 11 infants. Surgery failed to control reflux in two infants, although good control was obtained in the one who had subsequent surgery. Three infants required prolonged ventilation postoperatively; two of them died later from pulmonary failure. The median time to discharge was 24 days (8-113 days). All infants with intractable apnoea were cured by surgery. Fundoplication is an effective method of management when used early in the treatment of chronic gastro-oesophageal reflux in preterm infants. There is minimal morbidity from the surgical procedure.

Abstract
This study aimed to define the incidence and severity of gastro-oesophageal reflux (GOR), as measured using 24 hour oesophageal pH monitoring, in 38 infants with recurrent respiratory symptoms and to relate these findings to measures of respiratory function. Twenty one infants had a pH under 4 for more than 5% of the time (one definition of abnormal GOR) and nine had GOR exceeding age related normal values. Maximum expiratory flow at functional residual capacity was reduced in 37 infants, airways resistance was raised in 19 infants, and thoracic gas volume was abnormal in 11 infants. There was no association between indices of GOR and measures of lung function whether assessed by correlation or by chi 2 analysis for normal versus abnormal values. However, individual infants appeared to have respiratory symptoms produced by GOR. This suggests that host responsiveness to GOR may be of greater relevance than the amount of GOR.

Abstract
Gastroesophageal reflux (GER) usually presents with digestive symptoms, failure to thrive, and/or respiratory symptoms. During the 8-year period from 1981 to 1989, 1,153 children underwent 20-hour pH monitoring to assess GER. All patients were graded using the scoring system of Euler and Byrne. Patients were classified as severe (score greater than 50), moderate (score 25 to 50), and normal (score less than 25). Five hundred (43.3%) of these patients presented with respiratory symptoms including apnea, cyanosis, or "near miss" sudden infant death syndrome (36%), poorly controlled asthma (28%), recurrent bronchopneumonia (13%), bronchiolitis (9%), and miscellaneous symptoms such as intermittent dyspnea, chronic cough, and stridor (12%). Eight patients (2%) had cystic fibrosis. The ages ranged from 1 month to 20 years (mean, 19.5 months). Twelve patients had technically inadequate studies and were excluded. Severe reflux was present in 156 patients (31%) and moderate reflux in 159 patients (31%). All patients were treated initially by medical therapy for a minimum of 8 weeks. The majority of patients (81%) had resolution of their symptoms with change in position, thickened feedings, and, when indicated, additional therapy with metoclopramide, cisapride, or domperidone. Most of these patients were found to have a specific position, usually prone, which decreased reflux. The remaining 57 patients had documentation of persistent reflux by pH monitoring and underwent an antireflux procedure. Of those patients undergoing surgery 51 had severe reflux and 6 had moderate reflux. Forty-four patients had a posterior 270 degrees wrap (Toupet), 10 had a 360 degrees wrap (Nissen), and 3 had an anterior 180 degrees wrap (Boix-Ochoa).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Continuous monitoring of oesophageal pH is regarded as the gold standard for all reflux investigations. However, since gastro-oesophageal reflux is considered a normal phenomenon which occurs to a certain extent in each individual, the distinction between "normal" and "abnormal" is not always obvious and is not possible to achieve with a single test. Moreover, data depend on technical hardware such as recording devices and electrodes together with such patient characteristics as age, position, activity, and medication. Although much literature on pH monitoring has appeared recently, many investigations have failed to take into account the basic principles that are of major importance for any biomedical test such as reproducibility, sample reliability, and indications. There is a need to standardize the technique in order to compare studies performed in different centres, provided the technique is reproducible.

Abstract
Gastro-oesophageal reflux disease may result from a host of factors. Medical therapy has largely been aimed at neutralizing acid or decreasing acid production but improvement of upper-gastrointestinal motility may prove to be a valuable treatment modality as well. This paper reviews the current state of knowledge of the pathogenesis of reflux disease and concentrates upon promotility treatment with domperidone, metoclopramide and cisapride.
