Abstract
Objective To compare the growth curves (weight and length) of two groups of infants with isolated Robin sequence (RS) treated with nasopharyngeal intubation (NPI), one group receiving a hypercaloric diet and the other receiving a normal diet for age, and compare the growth rates and duration of NPI between the two groups. Design Prospective longitudinal study. Setting Hospital de Reabilitação de Anomalias Craniofaciais, Universidade de São Paulo, Bauru, Brazil, 1998 to 2000. Patients Twenty-three children with isolated RS treated by prolonged NPI. Interventions Nine children received a milk formula supplemented with 5% to 7% glucose polymers and 3% to 5% medium chain triglycerides (group 1), and 14 children received a milk formula only (group 2). Weight and length were measured at birth and every month up to 6 months of life for the construction of weight and length growth curves. The time of use of the nasogastric tube, age at the beginning of NPI, and duration of NPI were also determined. Results No significant difference in length was observed between the two groups. The mean weight curves obtained for the two groups were below the 50th percentile of the National Center for Health Statistics, but weight gain was higher in group 1. The duration of NPI was shorter in this group. Conclusions The hypercaloric diet led to an improvement in nutritional status, which in turn contributed to improved respiratory conditions in isolated RS.

Abstract
BACKGROUND AND OBJECTIVE Rabeprazole sodium is a proton pump inhibitor used for the treatment of gastroesophageal reflux disease (GERD). The objective of this study was to develop a population pharmacokinetic model for rabeprazole that describes concentration-time data arising from phase I and phase III studies in adult and pediatric subjects, including neonates and preterm infants, and propose dosing recommendations for pediatric subjects aged 1-11 years. METHODS A total of 4,417 pharmacokinetic observations from 597 subjects aged 6 days to 55.7 years with body weights of 1.15-100 kg were used to develop the population pharmacokinetic model using non-linear mixed-effects modeling techniques. Weight and age were included in the structural model to describe clearance (CL) and central volume of distribution (V c). Other covariates considered during model development included sex, race, creatinine clearance, hepatic function, formulation, feeding status, and route of administration. The final model was used to determine doses for pediatric subjects aged 1-11 years to achieve a steady-state area under the plasma concentration-time curve across the dose interval of 24 h (AUC24) within the target adult AUC24 range obtained following a rabeprazole 10 mg dose. RESULTS The best model was a two-compartment disposition model with a sequential zero-order duration of input (Dur), first-order absorption (k a) following a lag time (T lag), with weight and age effects on CL and V c. Formulation type and feeding status described some of the variability in bioavailability and the absorption parameters T lag, Dur, and k a. A dosage regimen of 5 mg once daily for children <15 kg, and 10 mg for children ≥15 kg is recommended for 1- to 11-year-old pediatric patients with GERD. CONCLUSIONS The pharmacokinetics of rabeprazole were described with good precision following administration of rabeprazole across a range of doses and in a range of formulations.

Abstract
BACKGROUND AND AIM Little is known about the relation between gastroesophageal reflux (GER) episodes and sleep interruptions in infants. The aim of the study was to evaluate the relationship between GER and the incidence of sleep interruptions in infants. METHODS Study patients included 24 infants (younger than 1 year) referred for multichannel intraluminal impedance and esophageal pH monitoring with simultaneous polysomnography. Exclusion criteria were a previous fundoplication and studies lasting <20 hours. Tests were clinically indicated to investigate suspicion of GER-related apnea (17, 70.8%), stridor (6, 25%), noisy breathing (2, 8.3%), and cyanotic spells (1, 4.2%). Most patients presented with significant comorbidities (19, 79.2%). RESULTS The number of nonacid GER (NAGER) per hour was greater during sleep time than during daytime and awakening following sleep onset (median 0.27 vs 1.85 and 1.45, P<0.01). A total of 1204 (range 7-86 per infant) arousals in 24 infants was detected, 165 (13.7%) that followed GER episodes, and 43 (3.6%) that preceded GER episodes. Seven patients presented with a positive symptom association probability for arousals; 5 were exclusively because of NAGER. A positive symptom association probability for awakenings was detected in 9 patients; 4 were because of NAGER, 4 were because of AGER, and 1 was because of both NAGER and GER. Patients with awakenings related to GER presented longer mean clearance time of AGER during sleep (165.5 vs 92.8 seconds, P=0.03). CONCLUSIONS GER was a frequent cause of interrupting sleep among our infant patients, and NAGER proved to be equally important as AGER for causing arousals and awakenings in infants.

Abstract
There is concern about possible consequences of gastroesophageal reflux (GER) in preterm infants. GER is perceived to be a frequent condition in these infants, often causing an exhaustive investigation and expensive therapy. We review current evidence for and against an association between GER and apnea, failure to thrive, wheezing and respiratory diseases. Although there are some limitations to the methodologies currently used for detecting GER, there is clearly a lack of unequivocal evidence supporting a causal relationship between GER and its assumed consequences, particularly in preterm infants. Despite physiologic data that stimulation of laryngeal efferents by GER may induce apnea, there is little evidence for a causal relationship between GER and apnea. Studies on preterm infants with failure to thrive have also not demonstrated an association between the latter and GER in most cases, and there is equally little evidence for a casual relationship with respiratory problems. Therefore, we believe that GER in preterm infants is only rarely associated with serious consequences and existing evidence does not support the widespread use of anti-reflux medications for treatment of these signs in this age group. An improvement of methods to identify the few preterm infants at risk for developing serious consequences of GER is urgently needed.

Abstract
The population pharmacokinetics of pantoprazole was characterized in pediatric patients from birth to 16 years using NONMEM and evaluated via bootstrap and predictive check. Data were described using a 2-compartment model with a typical parameterized in terms of clearance (CL) (95% CI) of 1.93 L per hour (1.53, 2.61), given the reference covariates (female, full term, extensive/unknown CYP2C19 metabolizer status, non-African American, 10 kg weight, intravenous or tablet administration). Pantoprazole pharmacokinetic parameters appear to be similar in pediatric patients compared to adults when allometrically scaled. The effect of age on allometrically scaled CL was best described by a sigmoid Emax model with the age effect reaching an asymptote approximately equal to the adult CL by 1 year. CYP2C19 poor metabolizers exhibited reduced CL with the point estimate and 95% CI more than 70% lower than the typical value. Simulations from the final model indicated that the 1.2-mg/kg dose provides the best comparison to adults.

Abstract
OBJECTIVE To study the prevalence of abnormal gastroesophageal reflux in infants with Robin sequence who had severe respiratory obstruction treated with nasopharyngeal intubation and to evaluate the efficacy of nonsurgical treatment. DESIGN Longitudinal prospective study. SETTING Hospital de Reabilitação de Anomalias Craniofaciais, University of São Paulo, Brazil. PATIENTS Twenty infants with severe isolated Robin sequence treated with nasopharyngeal intubation. INTERVENTIONS We performed 24-hour esophageal pH monitoring on each child at 2, 4, and 6 months of age. Respiratory and feeding status were evaluated. We considered abnormal gastroesophageal reflux as reflux index values above the 95th percentile of the Vandenplas reference for normal children. RESULTS The prevalence of reflux index above the 95th percentile at the first exam was 6/20, a value significantly higher than the reference (5/103, p < .01). At the second and third exams, reflux index values were decreased. Ninety percent of the infants showed improvement of respiratory difficulty and developed oral feeding capacity. CONCLUSIONS The prevalence of abnormal gastroesophageal reflux is higher in infants with severe cases of Robin sequence than in normal infants. Nonsurgical procedures improved respiratory and feeding difficulties of most of these infants.

Abstract
AIM To study the growth of infants with isolated Robin sequence (IRS) considered being severe cases during the first 6 months of life. METHODS Twenty infants with IRS, considered being severe cases were followed in a pure prospective longitudinal study. Feeding facilitating techniques were applied to all infants after airway disobstruction and a hypercaloric diet was offered. Weight and length were measured at birth and at 2-month intervals until 6 months of age. RESULTS The infants with severe IRS under study showed impaired weight and length growth from birth to 6 months of age when the values were compared to the NCHS2000 reference. CONCLUSIONS Malnutrition persisted in infants with severe IRS during the first 6 months of life despite the use of special diet and techniques developed for clinical recovery of this anomaly.

Abstract
Concerns regarding gastroesophageal reflux (GER) and associated apnea episodes result in some practitioners having convalescent, prematurely born infants sleep in the prone position. We have tested the hypothesis that such infants would not suffer from clinically important acid GER or associated apnea episodes more in the supine compared with the prone position. Lower esophageal pH was measured and videopolysomnographic recordings of nasal airflow, chest and abdominal wall movements, electrocardiographic activity, and oxygen saturation were made on two successive days of 21 premature infants (median gestational age 28 wk) at a median postmenstrual age (PMA) of 36 wk. On each day, the infants were studied prone and supine. The acid reflux index was higher in the supine compared with the prone position (median 3% versus 0%, p = 0.002), but was low in both positions. The number of obstructive apnea episodes per hour was higher in the supine position (p = 0.008). There were, however, no statistically significant correlations between the amount of acid GER and the number of either obstructive or total apnea episodes in either the supine or prone position. Supine compared with prone sleeping neither increases clinically important acid GER nor obstructive apnea episodes associated with acid GER in asymptomatic, convalescent, prematurely born infants.

Abstract
OBJECTIVES Metoclopramide is a commonly used drug to treat gastroesophageal reflux disease in infants. Given its widespread use and growing concern about toxicity in this population, we conducted a systematic review of metoclopramide for the treatment of gastroesophageal reflux disease in infants. METHODS We performed a systematic search of PubMed and bibliographies of relevant review articles. We included cohort, case-control, and intervention studies of the efficacy, effectiveness, or toxicity of metoclopramide therapy for gastroesophageal reflux disease in infants. We excluded case reports, case series, review articles, and abstracts. RESULTS Twelve articles met our inclusion criteria. Of these, 11 were prospective trials, and 5 were randomized, blinded clinical trials. Study size ranged from 6 to 77 patients. Eight studies showed patient improvement with metoclopramide in at least 1 measured outcome; 1 study showed worsening symptoms with metoclopramide. Of the 5 randomized, blinded trials, 2 showed no effect of metoclopramide on any outcome, and 2 showed a significant placebo effect. Four studies commented on adverse effects of therapy, with irritability being the most frequently reported potential adverse effect of therapy. Other reported adverse effects included dystonic reactions, drowsiness, oculogyric crisis, emesis, and apnea. Among studies, there was marked heterogeneity in the patient populations, dosing, and outcomes studied. Therefore, a meta-analysis was not performed. We both agreed on a US Preventive Service Task Force rating of "poor" for the level of evidence, leading to an "inconclusive" recommendation for the safety and efficacy of metoclopramide in infants. CONCLUSIONS The current literature is insufficient to either support or oppose the use of metoclopramide for gastroesophageal reflux disease in infants. In the future, large blinded randomized clinical trials are needed to determine the efficacy and toxicity of metoclopramide in this population.

Abstract
OBJECTIVE To determine the effectiveness of feeding-facilitating techniques in children with Robin sequence. SETTING Hospital de Reabilitação de Anomalias Craniofaciais, University of São Paulo, Bauru, São Paulo, Brazil. PATIENTS Twenty-six children less than 2 months of age with Robin sequence, whose only cause of respiratory obstruction was glossoptosis. Thirteen infants were treated by being placed in the prone position (Group 1), and 13 were treated by nasopharyngeal intubation (Group 2). INTERVENTIONS During hospitalization, the following feeding-facilitating techniques were applied daily to all children: pacifier, massage to relax and anteriorize the tongue, long and soft bottle nipple with original or enlarged hole, global symmetric position, rhythmic movement of the nipple during suction, and insertion of the nipple on the tongue. RESULTS During the first evaluation, Group 1 patients accepted 36.15 +/- 33.05 mL milk orally within a period of 44.62 +/- 42.94 minutes, whereas Group 2 ingested 20.00 +/- 20.51 mL milk within 30.38 +/- 25.77 minutes. A significant increase (p < .01) in the volume of ingested milk was observed for the two groups at hospital discharge after a mean treatment period of 10.7 days (Group 1: 63.46 +/- 22.58 mL and Group 2: 55.00 +/- 13.07 mL). The mean duration of feeding decreased in the two groups, with a value of 21.54 +/- 7.18 minutes for Group 1 and of 20.28 +/- 8.53 minutes for Group 2. CONCLUSION The results showed that feeding-facilitating techniques can foster oral feeding in infants with Robin sequence.

Abstract
OBJECTIVE To evaluate symptom improvement in 53 children (aged 5-11 years) with endoscopically proven gastroesophageal reflux disease (GERD) treated with pantoprazole (10, 20 and 40 mg) using the GERD Assessment of Symptoms in Pediatrics Questionnaire. METHODS The GERD Assessment of Symptoms in Pediatrics Questionnaire was used to measure the frequency and severity over the previous 7 days of abdominal/belly pain, chest pain/heartburn, difficulty swallowing, nausea, vomiting/regurgitation, burping/belching, choking when eating and pain after eating. Individual symptom scores were based on the product of the frequency and usual severity of each symptom. The sum of the individual symptom score values made up the composite symptom score (CSS). The primary end point was the change in the mean CSS from baseline to week 8. RESULTS Mean frequency and severity of each symptom significantly decreased (from P < 0.006 to P < 0.001) over time. Similar significant decreases in CSS at week 8 versus baseline (P < 0.001) were seen in all groups. Significant decreases from baseline in CSS were noted from weeks 1 to 8 in the 20-mg (P < 0.003) and 40-mg (P < 0.001) groups. The 20- and 40-mg doses were significantly (P < 0.05) more effective than the 10-mg dose in improving GERD symptoms at week 1. Adverse events were similar among the treatment groups. CONCLUSIONS Pantoprazole (20 and 40 mg) is effective in reducing endoscopically proven GERD symptoms in children. Both 20 and 40 mg pantoprazole significantly reduced symptoms as early as 1 week.

Abstract
Two gastroesophageal reflux disease (GERD) symptom questionnaires were developed and tested prospectively in a pilot study conducted in infants (1 through 11 months) and young children (1 through 4 years) with and without a clinical diagnosis of GERD. A pediatric gastroenterologist made the clinical diagnosis of GERD. Parents or guardians at 4 study sites completed the questionnaires, providing information on the frequency and severity of symptoms appropriate to the 2 age cohorts. In infants, symptoms assessed were back arching, choking or gagging, hiccups, irritability, refusal to feed and vomiting or regurgitation. In young children, symptoms assessed were abdominal pain, burping or belching, choking when eating, difficulty swallowing, refusal to eat and vomiting or regurgitation. Respondents were asked to describe additional symptoms. Symptom frequency was the number of occurrences of each symptom in the 7 days before completion of the questionnaire. Symptom severity was rated from 1 (not at all severe) to 7 (most severe). An individual symptom score was calculated as the product of symptom frequency and severity scores. The composite symptom score was the sum of the individual symptom scores. The mean composite symptom and individual symptom scores were higher in infants (P<0.001 and P<0.05, respectively) and young children (P<0.001 and P<0.05, respectively) with GERD than controls. Vomiting/regurgitation was particularly prevalent in infants with GERD (90%). Both groups with GERD were more likely to experience greater severity of symptoms. We found the GERD Symptom Questionnaire useful in distinguishing infants and young children with symptomatic GERD from healthy children.

Abstract
AIMS To examine the clinical use of litmus paper tests for the assessment of aspirates in infants. BACKGROUND In connection with establishing a programme for home care of infants with requirement of tube feeding with parents as the infants' carers, the need for a research-based method for verification of feeding tube position was identified by nurses as a complement to other methods. In adult care the litmus paper test is commonly used when visual inspection is not sufficient for assessment of aspirates obtained from feeding tubes. DESIGN Observational study. METHODS AND MATERIAL Nurses performed litmus tests for verification of feeding tube location in a convenience sample of 60 infants born at a gestational age (GA) of 24-42 weeks. Presence/absence and volumes of aspirates were recorded as well as positive/negative litmus test reactions. Analyses on the association between test results and the infants' GA and postmenstrual and postnatal age at the time of the tests were conducted. RESULTS Data were obtained from 2970 tube feeds. Aspirates were present on 1840 occasions (62%). A higher proportion of infants with absence of aspirates were born at a GA below 32 weeks. A positive reaction occurred in 97% of the tests in volumes between 0.01 and 22 ml. Birth at a GA below 32 weeks and respiratory problems were associated with negative tests. CONCLUSION The high ratio of positive litmus reactions at all maturational levels supports the bedside use of analysis of pH in gastric aspirates for verification of feeding tube location. RELEVANCE TO CLINICAL PRACTICE Application of pH indicator paper is recommended as a complementary method for assessment of aspirates from feeding tubes.

Abstract
Excessive crying is the most common problem presenting to the doctor in the first months of life in western industrialised societies, affecting up to 30% of infants. There has been an exponential increase in the diagnosis of gastro-oesophageal reflux disease (GORD) in babies who cry excessively over the past few decades, and many parents believe their crying infant "has reflux". This paper proposes that culturocentric assumptions have confused interpretation of research into GORD, and re-examines the findings of GORD research from the perspective of evolutionary biology. Evolutionary biologists argue that the human infant is an exterogestate foetus for at least the first six months of life, dependent on maternal co-regulation for optimal physiological function. However, infant-care practices in western industrialised societies shifted towards an emphasis on infant autonomy at the time of the Industrial Revolution. From the perspective of evolutionary biology, a misalignment between western culture and the biological expectations of the infant developed over two million years of evolution may result in excessive crying in less adapted babies. The key biocultural factors that impact on infant distress are feeding management, parental responsiveness, sensory nourishment and sleep management. When the concept of the human infant as an exterogestate foetus is integrated with the findings of GORD research, a hypothesis and its corollary emerge. This hypothesis proposes that infant GORD is a physiological manifestation of misalignment between biology and culture, and proposes, as a corollary, that if the impact of biocultural factors upon the physiology of otherwise well crying babies is not addressed in the first months of life, populations of infants who cry excessively may be predisposed to GORD after three to four months of age. If this hypothesis is correct, an integrated clinical approach to crying babies less than three to four months of age that considers feeding management (e.g., frequent feeds, breast- or bottle-feeding technique, referral to a lactation consultant, cow's milk allergy), parental responsiveness (e.g., prompt response to infant cues), sensory nourishment (e.g., sling or backpack, walks, massage) and sleep management (e.g., nocturnal co-sleeping) should, firstly, decrease crying when applied to infants less than three to four months of age, and secondly, decrease the incidence of GORD in these infants once they are older than three to four months of age. Thirdly, if this hypothesis is correct, combining the integrated approach with pharmaceutical intervention should improve outcomes in infants diagnosed with GORD.

Abstract
OBJECTIVE To study the clinical course of patients with Robin sequence (RS) during the first 6 months of life. DESIGN A longitudinal prospective study of children with RS. SETTING Hospital de Reabilitação de Anomalias Craniofaciais, Universidade de São Paulo, Bauru-SP, Brazil, 1997 and 1998. PATIENTS Sixty-two children were studied from hospital admission to 6 months of age. Thirty-three (53.2%) presented with probable isolated RS (PIRS), 25 (40.3%) presented with syndromes or other malformations associated with RS, and 4 (6.5%) presented with RS with neurological involvement. INTERVENTIONS The type of respiratory tract obstruction was defined by nasopharyngoscopy. The patients with type 1 and type 2 obstruction underwent nasopharyngeal intubation (NPI), and glossopexy was indicated in patients with type 1 obstruction who did not show clinical improvement with this procedure. Tracheostomy was indicated in patients with type 2 obstruction who did not show a good course after NPI, in patients with type 1 obstruction who did not show good course after glossopexy, and in patients with type 3 and type 4 obstruction. RESULTS Prone position treatment (PPT) or NPI was the definitive treatment in 25 cases (75.8%) of PIRS and in 13 cases (52%) of syndromes or other malformations. Among the children with type 1 obstruction, 24 (51.1%) were submitted exclusively to PPT and 12 (25.5%) to NPI. With the type 2 groups, only one (12.5%) received PPT, and three (37.5%) were treated exclusively with NPI. All 15 infants treated exclusively with NPI (24.4%) presented with good weight, length, and neuromotor development. CONCLUSIONS Most patients with PIRS and type 1 obstruction improved without surgical intervention. NPI should be the initial treatment in all patients with RS with type 1 and type 2 obstruction who present with important respiratory and feeding difficulties.
