Abstract
Background The best method to measure the frequency and duration of gastroesophageal reflux is 24-h pH or 24-h pH/impedance monitoring. However, the detection of reflux can vary when measured on different days. Our aim was to evaluate the possibility that the severity of gastroesophageal reflux is different even under similar conditions on two consecutive days. Methods We performed a 48-h pH monitoring in 12 subjects, aged 25 - 63 years, who complaint of heartburn and regurgitation, ten with esophagitis and two with non-erosive disease. The pH measurement was conducted at 5 cm from the lower esophageal sphincter. The patients stayed at the Clinical Investigation Ward of the hospital for 48 h. On each day, they consumed a 2,000 calorie diet. The results obtained on the first day were compared with those on the second day. Results Mean reflux index in the upright position was different between the two days. Results of the pH-monitoring within the 2 h after the meal revealed differences in the number of acidic reflux and reflux index episodes. Three patients had abnormal DeMeester score on one day and normal score on the other day. Considering the upper limit of 6.0% of the test duration with esophageal pH < 4 as indicative of gastroesophageal reflux disease, two patients showed abnormal results on one day and normal results on the other day. Conclusions The 24-h pH monitoring, performed on two consecutive days under similar conditions, can lead to different diagnosis of gastroesophageal reflux disease in symptomatic patients.

Abstract
Cystic fibrosis is a chronic, life-shortening illness that affects multiple systems and results in frequent respiratory infections, chronic cough, fat malabsorption and malnutrition. Poor sleep is often reported by patients with cystic fibrosis. Although objective data to explain these complaints have been limited, they do show poor sleep efficiency and frequent arousals. Abnormalities in gas exchange are also observed during sleep in patients with cystic fibrosis. The potential impact of these abnormalities in sleep on health and quality of life remains largely unstudied. This review summarizes what is known about sleep in children with cystic fibrosis, and implications for clinical practice. This report also highlights new evidence on the impact of sleep problems on disease-specific outcomes such as lung function, and identifies areas that need further exploration.

Abstract
The aim of this study is to describe the prevalence of gastroesophageal reflux disease (GERD) in infants under 3 months old with a history of cyanotic episodes, who were examined at the emergency room of a university hospital. This descriptive study reviews reports of esophageal pH monitoring from a pediatric gastroenterology service over a period of 5 years. The following data were collected: age, sex, pediatric as well as other specialists' evaluations, and the esophageal pH monitoring reports. This study included 67 infants with a history of cyanotic episodes, with no primary cause determined by pediatrician and pediatric specialists' evaluations, who underwent esophageal pH monitoring. The infants were 6-90 days old, 41 (61.2%) of them male. Fifty infants (74.6%) had at least one esophageal pH monitoring parameter above the normal limit. ZMD index was abnormal in 32 cases (48%) and reflux index was abnormal in 31 cases (46%). When other common causes of cyanosis have been ruled out, a significant proportion of infants presenting cyanosis have abnormal pH study, suggesting the role of GERD in cyanosis. The authors highlight that reflux index is not enough to conclude whether a pH study is normal or not. The ZMD index and the presence of episodes longer than 20 minutes are also important parameters for GERD diagnosis.

Abstract
Untreated sleep disturbances and sleep disorders pose significant adverse daytime consequences and place children at considerable risk for poor health outcomes. Sleep disturbances occur at a greater frequency in children with acute and chronic medical conditions compared with otherwise healthy peers. Sleep disturbances in medically ill children can be associated with sleep disorders, comorbid with acute and chronic conditions, or secondary to underlying disease-related mechanisms, treatment regimens, or hospitalization. Clinical management should include a multidisciplinary approach with particular emphasis on routine, regular sleep assessments and prevention of daytime consequences, and promotion of healthy sleep habits and health outcomes.

Abstract
BACKGROUND The prevalence of gastroesophageal reflux (GER) in children with asthma is higher than in healthy controls, but the nature and direction of this association is unclear. OBJECTIVE The aim of our study was to assess the relationship between esophageal acid exposure and the clinical features of asthma in children. METHODS In total, 66 children (mean age 122.8 months [SD 44.89 months]) with chronic pulmonary symptoms, fulfilling diagnostic criteria of persistent asthma, underwent 24-hour esophageal pH monitoring and answered a detailed questionnaire-based survey. The questionnaire topics included environmental factors, familial history, current and previous clinical symptoms, atopy, asthma severity, and medication. RESULTS Abnormal results of 24-hour esophageal pH monitoring were found in 28 out of 66 children (42.4%). Age, sex, severity of asthma, environmental factors, spirometry results, and the type of medication did not correlate with esophageal acid exposure. However, children with abnormal pH results developed asthma significantly earlier (asthma onset 3.63 years [SD 2.52 years] vs 5.77 years [SD 3.82 years]; p < .01). Nonatopic individuals had more intensive esophageal acid exposure than atopic ones (Boix-Ochoa score 28.19 [SD 18.26] vs 18.26 [SD 12.84]; p < .048). The intensity of GER was also significantly correlated with frequent or difficult-to-control nighttime asthma attacks. CONCLUSIONS There are differences in clinical features of asthma in children with regard to the intensity of esophageal acid exposure. Symptoms of asthma in nonatopic individuals with early onset and difficult-to-control nighttime asthma attacks suggest the possibility of concomitant, clinically relevant GER.

Abstract
INTRODUCTION Laryngopharyngeal reflux is perhaps the most extensively researched laryngology topic of the last decade. It has been suggested that some supraoesophageal symptoms, most notably asthma and laryngospasm, may be associated with night-time, or supine, reflux. The aim of this review was to assess the levels of evidence regarding a correlation between night-time reflux, snoring and apnoea. METHODS A Medline search was performed using the terms 'reflux', 'night-time', 'larynx', 'gastroesophageal', 'laryngopharyngeal', 'sleep', 'apnoea', 'snoring' and 'ear nose throat'. The retrieved literature was reviewed, focusing on randomised and non-randomised, controlled, prospective trials. Papers on both paediatric and adult populations were included. Non-English language papers were excluded. RESULTS We found no randomised, controlled trials or meta-analyses addressing the possible correlation between reflux and snoring and/or apnoea. CONCLUSIONS The role of night-time reflux in paediatric and adult snoring and apnoea is well described in the literature, but is based on poor levels of evidence from uncontrolled studies and case reports.

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
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
BACKGROUND/PURPOSE Laparoscopic Nissen fundoplication (LNF) is utilized in the management of symptomatic gastroesophageal reflux disease (GERD) in children. An effective length of fundoplication and bougie size has never been established in infants and children requiring LNF for GERD. To determine this effective fundoplication length and appropriate bougie size, we analyzed all patients less than 15 kg undergoing LNF for GERD over a 2-year period. METHODS Data recovered retrospectively included age, weight, gender, need for gastrostomy, length of postoperative hospitalization, operating time, bougie size, and fundoplication length. RESULTS One hundred patients weighed less than 15 kg (mean, 7.23 kg). Mean operating time was 95 minutes (range, 31 minutes to 159 minutes). Gastrostomies were placed in 32 patients. Postoperative hospitalization averaged 1.8 days for elective LNF. Fundoplication length was measured in each patient and averaged 2.06 cm. Bougie size varied from 22F to 42F, and the size utilized was based on the patient's weight. There were no instances of dysphagia or the need for esophageal dilatation postoperatively. Two patients have been seen for recurrent symptoms. One patient has required a second LNF, and the other has a normal upper gastrointestinal study and pH study. CONCLUSION This study of LNF in small children has shown that resolution of GERD symptoms in most patients can be accomplished with an average fundoplication length of approximately 2 cm and a graduated bougie size relative to the patient's weight.

Abstract
Minimally invasive surgical approaches to various pediatric surgical disease processes are becoming the standard of care. Laparoscopic Nissen fundoplication is transitioning toward the preferred method for the surgical correction of gastroesophageal reflux (GER) disease in infants and children that do not respond to medical management or have complications from their GER. This approach offers a shorter hospitalization, reduced discomfort, and cosmetic advantages when compared with the open operation. This report discusses the pathophysiology of GER, its clinical manifestations, and the diagnostic evaluation for this disorder. Also, the laparoscopic Nissen fundoplication technique currently utilized at Children's Mercy Hospital is described.

Abstract
OBJECTIVES Aspiration of gastric contents is a relatively common cause of acute and chronic pulmonary disease. However, a reliable method of diagnosing recurrent aspiration is currently lacking. The aim of this study was to determine whether the presence of gastric pepsin in tracheal aspirates of infants and children might be used as a reliable marker of the microaspiration of refluxed gastric contents. METHODS Ninety-eight children undergoing general anesthesia and tracheal intubation participated in the study. Sixty-four of 98 children underwent endoscopy for clinically significant gastroesophageal reflux. Thirty-four children from routine operative lists were nonreflux controls. These two groups were further subdivided based on the presence or absence of associated respiratory symptoms. After endotracheal intubation, tracheal aspirates were obtained and subsequently assayed for gastric pepsin using a fluoroscein isothiocyanate casein. RESULTS Pepsin was detected in 7 of 27 children with reflux symptoms alone and in 7 of 8 of those with chronic respiratory symptoms. In addition, pepsin was present in 31 of 37 children with a history of both reflux and chronic respiratory symptoms. Tracheal pepsin was not detected in any of the 26 children without gastroesophageal reflux or respiratory symptoms. Tracheal pepsin was found significantly more frequently in children with reflux symptoms than in those without, particularly in children with both reflux and respiratory problems. CONCLUSION Tracheal pepsin assay as a reliable marker of gastroesophageal reflux aspiration.

Abstract
BACKGROUND To determine normal ranges of gastroesophageal reflux (GER) in the proximal esophagus, measured with continuous pH monitoring. Normal ranges in the distal esophagus have been published. Because esophageal pH monitoring is frequently performed in children with atypical manifestations such as chronic respiratory disease, and because one of the possible pathophysiologic mechanisms may be (micro-)aspiration, it may be relevant to establish normal ranges in the proximal esophagus. METHODS Twenty-four-hour pH monitoring was performed in 200 children with suspected GER disease. The mean age of the patients was 4.5 months (range, 0.5-17.0 months). After initial analysis, patients were divided into three groups according to the reflux index (RI) in the distal esophagus, because it could be speculated that the amount of reflux reaching the proximal esophagus depends on the amount of reflux in the distal esophagus: Group I (n: 120) children had a distal RI of less than 5% and were considered normal, group II (n:50) had a distal RI of 5% to 10% and was considered to have intermediate disease, and group III (n:30) had a distal RI of more than 10% and was regarded as pathologic. The following parameters are calculated: the RI, the total number of reflux episodes, the number of reflux episodes lasting more than 5 minutes, the duration of the longest reflux episode, and the acid clearance time (ACT). RESULTS The median RI in the distal esophagus was 3.8 +/- 0.34 (standard error of the mean [SEM]), and in the proximal esophagus, the RI was 1.2 +/- 0.23. In group I patients, the RI in the proximal esophagus was 0.5% +/- 0.09%, in group II the RI increased significantly to 2.75% +/- 0.34% (P [group I compared with group II] < 0.01), and in group III the RI was 6.15% +/- 0.96% (P [II-III] < 0.01). The number of acid reflux episodes in group I was 17.0 +/- 2.27, in group II the number increased to 62.5 +/- 8.18 (P [I-II] < 0.01), and in group III it reached 102.0 +/- 23.9 (P [II-III] < 0.05). Also the duration of the longest reflux episodes and the number of reflux episodes lasting more than 5 minutes increased from group I to group II, and from group II to group III. The ACT was shorter in the proximal esophagus (group I 0.3 +/- 0.06 minutes; group II 0.48 +/- 0.07 minutes, P [I-II] = not significant [NS]; group III 0.56 +/- 0.17 minutes P [II-III] = NS) than in the distal esophagus (group I 0.49 +/- 0.03 minutes, P [proximal ACT compared with distal ACT] < 0.05; Group II 0.76 +/- 0.05 minutes, P [proximal-distal] < 0.01; Group III 0.89 +/- 0.09 minutes, P [proximal-distal] = NS) suggesting more effective esophageal clearance in the proximal esophagus. CONCLUSIONS Protection of the proximal esophagus from acid reflux is significantly related to the incidence and duration of reflux measured in the distal esophagus. These normal ranges in the upper esophagus will be helpful in the interpretation of upper esophageal pH monitoring data.

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
PURPOSE The aim of this study was to analyze the indications and results of fundoplication in 110 infants under 3 months of age. METHODS A retrospective review was conducted on the charts of all infants operated on for gastroesophageal reflux disease (GERD) at the UCLA Medical Center from January 1980 to December 1997. There were 59 boys and 51 girls. Recurrent emesis was the indication for operation in 62 of 110 infants, and respiratory symptoms in 85 of 110, with 54 of 110 having both. Neurological impairment was present in 32%. Prematurity was present in 21%; 35% had associated anomalies. Overall, 81 of 110 infants (73.6%) had one or more associated major malformations or disorders. Reflux was confirmed by upper gastrointestinal series findings in 63 of 78, esophageal pH monitoring in 60 of 62, and endoscopy in five of seven. RESULTS Mean age at operation was 1.8+/-0.1 months and mean weight was 3,686+/-90.2 g. A Nissen fundoplication was performed on 104 children, and six underwent a Thal procedure. Thirty-one had a gastric emptying procedure for delayed gastric emptying. Complications occurred in 7 infants. Emesis was controlled in 57 of 62 patients, aspiration in 38 of 48, and apneic spells in 54 of 57. Follow-up greater than 6 months was available for 73 patients. There were nine late deaths, all related to severe associated malformations. Seven patients required a redo fundoplication for recurrent reflux. CONCLUSIONS Nissen fundoplication can be performed safely in symptomatic infants under 3 months of age with low mortality and morbidity rates and with resolution of the presenting symptoms in 79% of infants.

Abstract
Gastroesophageal reflux is a common pediatric complaint and a frequent reason for pediatric patients to be referred to a gastroenterologist. The pathophysiology and clinical manifestations of this disorder differ according to patient age. The diagnosis is suggested by the history and can be confirmed by a pH probe. In the appropriate clinical setting, anatomic obstruction may need to be ruled out by contrast study. Endoscopy is used to assess associated complications, including esophagitis, esophageal strictures, Barrett's transformation, and failure to thrive. Other complications are controversial, including pulmonary disease, apnea, and sudden infant death syndrome. Treatment depends on the severity of disease. Conservative therapy includes behavorial modifications, prokinetic agents, and H2 antagonists. Proton pump inhibitors are generally reserved for refractory esophagitis. Surgical treatment may be necessary for gastroesophageal reflux resistant to medical management or for severe complications. Gastroesophageal reflux beyond infancy tends to be chronic; therefore, lifelong behavioral modifications or repeated courses of medical therapy may be necessary. An algorithm for the suggested diagnostic approach to gastroesophageal reflux is presented herein.

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
Gastroesophageal reflux is often overlooked as both a cause and a complication of respiratory disease in children. The manifestations may be protean and may bear little clinical relationship to the gastrointestinal tract. However, a high index of suspicion for its potential role in unexplained respiratory symptoms may yield large benefits for the physician and patient alike.

Abstract
The etiology and prevention of sudden infant death syndrome (SIDS) are among the more frustrating topics in pediatrics. This article addresses several clinically relevant issues, including the relationships between apnea and SIDS, the nature of the "terminal event," effectiveness of home monitoring, the role of gastroesophageal reflux in apparent life-threatening events, and the association between the prone sleeping position and SIDS. This article is intended to provide the clinician with an awareness of the issues and the scientific basis needed to understand their contribution to SIDS.

Abstract
Recurrent gastroesophageal reflux (GER) after antireflux procedures (ARP) has been correlated with significant neurological impairment (NI). Other major risk factors for recurrent GER have not been extensively characterized. The authors reviewed their experience with ARPs in children to better characterize the risk factors for recurrent GER and identify successful management strategies for these patients. The charts of 281 consecutively treated children who had an ARP at our institution (1985 to 1992) were reviewed. The neurological status of each child was assessed as normal or impaired (cerebral palsy, seizures, mental retardation, spasticity), and other medical diagnoses such as chronic pulmonary disorders (eg, interstitial disease, cystic fibrosis, bronchopulmonary dysplasia, asthma, etc), and congenital malformations and syndromes were identified. The average follow-up period was 3 years (range, 1 to 7.5 years). Patients with symptoms of recurrent GER were evaluated with an upper gastrointestinal study. Patients with a radiologically intact fundoplication and suspected GER were further evaluated with a 24-hour pH probe. Statistical analyses were performed using the Fisher's Exact Test. Of the 281 patients who underwent ARP, 39 had documented recurrent GER (average, 16 months after surgery). Twenty-five (64%) of these children had chronic pulmonary disease (CPD). Thirty-two percent of all children with CPD had recurrent GER after ARP, versus 7% of those without CPD (P < .0001). For children with NI and CPD there was an increased risk (P < .0001) of failure when compared with the risk in the normal subgroup (children without CPD or NI) who underwent ARP.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Operations for the control of complicated gastroesophageal reflux in children are commonly performed procedures in large pediatric centers. The comprehensive diagnostic scheme includes radiologic and endoscopic work-up coupled with extended pH probe analysis. Medical therapy remains the principle form of management, with surgery reserved for treatment failure.

Abstract
The original diagnostic 24 hour pH monitoring data in 57 children with gastro-oesophageal reflux (GOR) were retrospectively reviewed after a minimum of one year follow up. The tracings of children who responded to medical treatment were compared with those who failed to respond and required a fundoplication. Children with GOR secondary to oesophageal atresia/tracheo-oesophageal fistula and neurological conditions (n = 12) were analysed separately from those with primary GOR (n = 45). Children with primary GOR requiring a fundoplication (n = 9) had increased daytime reflux. The percentage time pH < 4 was the best discriminator (21% v 7%) with a threshold of 18% giving a 92% specificity and a 70% sensitivity. For children with secondary GOR the percentage time pH < 4 at night was significantly higher (29% v 3.7%) in those requiring a fundoplication (n = 5). A threshold of 18% gave an 80% specificity and an 86% sensitivity. These results show that both daytime and night time pH monitoring data can be of prognostic value in different subgroups of children with GOR. A percentage time pH < 4 of greater than 18% was a useful threshold to apply when evaluating the pH monitoring data.

Abstract
An understanding of gastroesophageal reflux disease in infants and children by the clinician requires a working knowledge of 18- to 24-hour esophageal pH monitoring and the motility disorders of the esophagus and stomach that may be associated with gastroesophageal reflux disease. The results of surgical therapy for childhood gastroesophageal reflux disease cannot be assessed accurately without this knowledge. Antireflux operations can be tailored to the child's situation, which includes a combination of clinical symptoms and findings on objective tests for reflux and associated alimentary-tract motility disorders. The presence of severe complications from gastroesophageal reflux disease in "asymptomatic" infants and children is a troublesome and not yet fully defined problem. Special areas include the documentation of gastroesophageal reflux disease as a cause of SIDS, the increased reporting of Barrett's esophagus and adenocarcinoma of the esophagus in childhood, and the effect of associated alimentary-tract motility disorders in children with CNS disease who have gastroesophageal reflux disease requiring surgical intervention.

Abstract
Gastroesophageal reflux (GER) has been a suspected cause of infant deaths and sudden infant death syndrome (SIDS). We examined our 10-year experience with 499 consecutive infants 6 months of age or less who had extended (18 to 24 hours) esophageal pH monitoring performed to evaluate for GER. The data extracted from the esophageal pH records included the pH score, the pattern of GER (type I, II, or III), and the mean duration of reflux during sleep (ZMD). All infants were followed to determine the occurrence and cause of death during the first year of life. Of the 19 deaths found in the series, three were classified as SIDS and two were in-hospital deaths caused by reflux-induced aspiration. All five of these infants who died had a prolonged ZMD (greater than 3.8 minutes) and received either basic medical (n = 4) or no (n = 1) antireflux therapy. Four infants also had the type I pattern of GER. There was a 9.1% (4/44; 95% confidence limits, 2.5% to 21.7%) incidence of reflux-related or SIDS deaths in infants with type I GER and a prolonged ZMD who were treated nonoperatively, compared with none (0/83, P = .03) in the same group of infants treated with antireflux surgery. The incidence of SIDS was higher in infants with type I GER and a prolonged ZMD who were treated nonoperatively (3/44, 6.8%) compared with all other infants treated nonoperatively (0/265, 0%; P = .003).(ABSTRACT TRUNCATED AT 250 WORDS)
