Abstract
Nutritional management of children with severe neurological impairment (SNI) is highly complex, and the profile of this population is changing. The aim of this narrative review was to give the reader a broad description of evolution of the nutritional management of children with SNI in a high resource setting. In the last decade, there has been an emphasis on using multiple anthropometric measures to monitor nutritional status in children with SNI, and several attempts at standardising the approach have been made. Tools such as the Feeding and Nutrition Screening Tool, the Subjective Global Nutrition Assessment, the Eating and Drinking Ability Classification System and the Focus on Early Eating and Drinking Swallowing (FEEDS) toolkit have become available. There has been an increased understanding of how the gut microbiome influences gastrointestinal symptoms common in children with SNI, and the use of fibre in the management of these has received attention. A new diagnosis, 'gastrointestinal dystonia', has been defined. The increased use and acceptance of blended food tube feeds has been a major development in the nutritional management of children with SNI, with reported benefits in managing gastrointestinal symptoms. New interventions to support eating and drinking skill development in children with SNI show promise. In conclusion, as the life expectancy of people with SNI increases due to advances in medical and nutrition care, our approach necessitates a view to long-term health and quality of life. This involves balancing adequate nutrition to support growth, development and well-being while avoiding overnutrition and its associated detrimental long-term effects.

Abstract
Electrogastrography (EGG) is a novel diagnostic modality for assessing the gastrointestinal tract (GI) that generates spontaneous electrical activity and monitors gastric motility. The aim of this study was to compare patients with functional dyspepsia (FD) and diabetic gastroparesis (D-GP) with healthy controls (CT) to use established findings on abnormalities of gastric motility based on EGG characteristics. In this study, 50 patients with FD, 50 D-GP patients, and 50 CT subjects were studied to compare EGG with discrete wavelet transform models (DWT) to extract signal characteristics using a variety of different qualitative and quantitative metrics from pre-prandial and postprandial states. As a result, higher statistically significant (p < 0.05*) were found in the DWT models based on power spectral density (PSD) analysis in both states. We also present that the correlations between EGG metrics and the presence of FD, D-GP, and CT symptoms were inconsistent. This paper represents that EGG assessments of FD and D-GP patients differ from healthy controls in terms of abnormalities of gastric motility. Additionally, we demonstrate that diverse datasets showed adequate gastric motility responses to a meal. We anticipate that our method will provide a comprehensive understanding of gastric motility disorders for better treatment and monitoring in both clinical and research settings. In conclusion, we present potential future opportunities for precise gastrointestinal electrophysiological disorders.

Abstract
Intestinal motility disorders represent a frequent problem in children with neurological impairment. These conditions are characterized by abnormal movements of the gut, which can result in symptoms such as constipation, diarrhea, reflux, and vomiting. The underlying mechanisms leading to dysmotility are various, and the clinical manifestations are often nonspecific. Nutritional management is an important aspect of care for children with gut dysmotility, as it can help to improve their quality of life. Oral feeding, when safe and in the absence of risk of ingestion or severe dysphagia, should always be encouraged. When oral nutrition is insufficient or potentially harmful, it is necessary to switch to an enteral by tube or parenteral nutrition before the onset of malnutrition. In most cases, children with severe gut dysmotility may require feeding via a permanent gastrostomy tube to ensure adequate nutrition and hydration. Drugs may be necessary to help manage gut dysmotility, such as laxatives, anticholinergics and prokinetic agents. Nutritional management of patients with neurological impairment often requires an individualized care plan to optimize growth and nutrition and to improve overall health outcomes. This review tries to sum up most significant neurogenetic and neurometabolic disorders associated with gut dysmotility that may require a specific multidisciplinary care, identifying a proposal of nutritional and medical management.

Frequency-specific electrogastrography as a non-invasive tool to measure gastrointestinal maturity in preterm infants. Sci Rep 2022; 12:20728. [PMID: 36456633 PMCID: PMC9715709 DOI: 10.1038/s41598-022-24110-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Accepted: 11/10/2022] [Indexed: 12/05/2022] Open
Abstract
Enteral feeding is challenging in preterm infants because of gastrointestinal (GI) immaturity. Electrogastrography (EGG) is a non-invasive technology that measures gastric myoelectrical activity and can be utilized to measure changes that occur with maturation at different gestational ages (GA). Three gastric rhythms (GR) exist between 0.5-9 cycles per minute (cpm), namely, bradygastria (0.5 ≤ GR < 2 cpm), normogastria (2 ≤ GR < 4 cpm), and tachygastria (4 ≤ GR < 9 cpm). We aimed to characterize EGG-derived parameters for different GA by quantifying (1) power spectral density (PSD) and its spectral means at three GR bands (i.e., mPSDGR) and (2) the percent (%) time spent in each band. Data analyzed was from a longitudinal cohort of preterm infants (n = 51) born at early, mid, and term GA of < 29, 29-33, and ≥ 37 weeks, respectively. Weekly EGG monitoring was performed until 40 weeks' postmenstrual age or discharge. Pre-, during, and post-feed data were analyzed for mPSDGR at each GR band. Also, % bradygastria, % normogastria, and % tachygastria were calculated by continuous wavelet transform analysis. Results showed (1) mPSD values in normogastria and tachygastria during feeding increased with advancing GA, and (2) % normogastria increased with advancing GA regardless of GR ranges, suggesting EGG may measure GI maturity in preterm infants.

Abstract
Nutrition plays an important role both from a nutrition and a socio-psychological point of view; this part seems to be even more crucial in cerebral palsy where undernutrition is responsible for an increase in morbidity and mortality. The objective of this study was to evaluate the effects of swallowing disorders and oral malformations on the nutritional status of children with cerebral palsy. We evaluated 65 patients aged 2 to 17 years using a cross-sectional, descriptive and observational approach. All patients had a definite diagnosis of cerebral palsy. The measurement of anthropometric variables (weight, height, Body Mass Index (BMI) and circumferences) was performed according to recognized techniques and measurements. The Z-score was also calculated using the World Health Organization (WHO) references. The 5-level Gross Motor Function Classification System was used, providing a standardized classification of motor disability patterns for children with cerebral palsy. The population had a median age of 9.25 (4.50−16.00) and was about 53% female. Furthermore, 75% of the patients had a height inferior to 158 cm. The results of our study show that 42 (64.6%) had false routes, 17 (26.2%) had oral-facial malformations and 51 (78.5%) did not have lip prehensions during meals. The results also show that growth retardation is closely related to gross motor function with p = 0.01, as well as all nutritional indices (Z-score weight for age, Z-score height for age and Z-score BMI for age) are affected by swallowing disorders and oral malformations, with statistically significant values < 0.05. In conclusion, a preventive and curative management specific to this population of children with cerebral palsy must be implemented with an interdisciplinary concertation.

Abstract
INTRODUCTION Gastrojejunal (GJ) tubes are becoming an established alternative method of delivering nutrition to children who do not tolerate gastric feeding. However, there is limited literature surrounding patient outcomes, the longevity of tubes or complications. We aim to highlight the development and evaluation of a service to provide children with GJ tube feeding. MATERIALS AND METHODS A retrospective case-note review of children either undergoing an initial gastrostomy to gastrojejunal tube conversion or gastrojejunal tube replacement in our tertiary paediatric surgical centre between January 2015 and June 2018. RESULTS 134 GJ feeding tubes were placed in 33 neurologically impaired children with a median age of 4.9 years (8 months-17 years) having a median 4 tube placements per child (1-11) within the study period. All tubes were 14 or 16 Fr 'AMT G-JET' tubes with a median replacement time of 174.9 days (13-504 days). The most common indication was foregut dysmotility in children with global developmental delay. The complication rate was 34.3% (46 tubes). In the study period, 2 patients (6.1%) reverted to oral feeding, 6 patients (18.2%) to gastric feeding and 25 children (75.7%) continued with jejunal feeding. No child required fundoplication. There were no procedure-related mortalities or mortality. CONCLUSIONS GJ tube feeding is an effective and safe method of managing children with foregut dysmotility. Many patients do not require permanent jejunal feeding, and thus the reversibility of this method is an asset. A dedicated team is needed to co-ordinate tube replacements and provide efficient long-term jejunal feeding. LEVEL OF EVIDENCE IV.

Abstract
Pre-operative nutritional assessments have been used as a "cornerstone" to help optimize nutritional status and weight in children with cerebral palsy (CP) to lower the risk of postoperative complications. However, the potential value of nutritional assessments on surgical outcomes in patients with CP undergoing major orthopedic surgery remains unproven.Do pre-operative nutritional assessments reduce complication rates of varus derotational osteotomy surgery in children with CP? Are complication rates higher in patients with a gastrostomy tube (G-tube) and can they be decreased by pre-operative nutritional assessment?One-hundred fifty-five patients with CP who underwent varus derotational osteotomy from January 1, 2012 through December 31, 2017 at a tertiary pediatric hospital with minimum 6 months follow-up were retrospectively identified. One-hundred-ten (71%) were categorized as "non-ambulatory" (Gross Motor Function Classification System [GMFCS] IV-V), and 45 (29%) as "ambulatory" (GMFCS I-III). Variables assessed included age, GMFCS level, G-tube, body mass index (BMI) percentile, complications, and if patients underwent pre-operative nutritional assessment.One-hundred-eleven patients (71.6%) underwent pre-operative nutritional assessment. Sixty-two of 155 patients (40.0%) had G-tubes. In non-ambulatory patients with G-tubes, BMI percentile changes were not significantly different between patients with a pre-operative nutritional assessment compared to those without at 1 (P = .58), 3 (P = .61), 6 (P = .28), and 12 months (P = .21) postoperatively. In non-ambulatory patients who underwent pre-operative nutritional assessment, BMI percentile changes were not significantly different between those with and without G-tubes at 1 (P = .61), 3 (P = .71), 6 (P = .19), and 12 months (P = .10). Pulmonary complication rates were significantly higher in non-ambulatory patients with G-tubes than in non-ambulatory patients without G-tubes (20% vs 4%, P = .03). Pre-operative nutritional assessments did not influence postoperative complication rates for non-ambulatory patients with or without a G-tube (P = .12 and P = .16, respectively). No differences were found in postoperative complications between ambulatory patients with and without G-tubes (P = .45) or between ambulatory patients with or without nutritional assessments (P = .99).Nutritional assessments, which may improve long term patient nutrition, should not delay hip surgery in patients with CP and progressive lower extremity deformity. Patients and their families are unlikely to derive any short-term nutritional improvement using routine pre-operative evaluation and surgical outcomes are unlikely to be improved.Level of Evidence: III, retrospective comparative.

Abstract
ABSTRACT Objective: To correlate the nutritional status with variables associated to the type of diet and feeding route of children and adolescents with spastic quadriplegic cerebral palsy (CP). Methods: This cross-sectional study included 28 patients aged ≤13 years old who presented a diagnosis of spastic quadriplegic CP and were followed by the nutrition team of the Outpatient Clinic for Special Patients of Hospital de Clínicas de Uberlândia - Universidade Federal de Uberlândia (HC-UFU), between July/2016 and January/2017. Consent forms were signed by the legal guardians. The nutritional status was evaluated and data on dietary complications food route and type of diet were collected. For the description of data, average and median values were used. Correlation was tested with Spearman’s index. Significance was set at p<0.05. Results: 75% of patients used alternative feeding routes (nasoenteral, catheter or gastrostomy), 57% were eutrophic. The most frequent complications were oropharyngeal dysphagia, reflux and intestinal constipation. No correlation was found between the occurrence of complications and the nutritional status. There was a positive correlation between the diet received and the patient’s nutritional status (0.48; p=0.01), i.e. individuals with adequate caloric and macronutrients intake had a better nutritional status. Conclusions: The results reinforce the need for continued nutritional guidance for the children’s parents/caregivers, as well as the choice of an adequate rout of feeding to each child by the multi-professional team, in order to contribute to improved nutritional status and adequate dietary intake.

Abstract
PURPOSE To clarify the characteristics of gastroesophageal reflux (GER) in pediatric patients with neurological impairment (NI). METHODS Twenty-six patients with NI, 1-17-year-old, fed via a nasogastric tube were categorized based on the absence (group I) or presence (group II) of abnormal GER, defined with multichannel intraluminal impedance-pH monitoring as %time with an esophageal pH <4.0 being ≥5.0% or number of liquid/mixed bolus reflux events(RE) >70 in 24 h. RESULTS %Time and number of distal and proximal bolus REs were not significantly different between acid and nonacid REs. %Time of acid bolus RE and that of acid and total number of distal and proximal bolus REs were significantly higher in group II than in group I. Mean acid clearance time was significantly longer in group II. Median bolus clearance time was similar between the groups. No bolus RE parameters were significantly different between acid and nonacid REs in group I. Acid bolus RE was significantly higher than nonacid RE in terms of %time and number of proximal bolus RE in group II. CONCLUSION Acid REs significantly increased in pediatric patients with NI with abnormal GER. The number of acid and nonacid REs was comparable in patients without abnormal GER.

Abstract
Neurogenic bowel dysfunction occurs in a large percentage of adult patients with spina bifida (SB) and spinal cord injury (SCI), significantly affecting their quality of life. Although bowel motility is autonomously regulated by the enteric nervous system (ENS), disruption of the modulation of the ENS by extrinsic innervation as present in many patients with SB and SCI might lead to motility disorders. In order to gain insight in the pathophysiology, we studied histological changes of the neuromuscular structures in the colon of SB and SCI patients. Archival colon tissue blocks from SB (n = 13) and SCI (n = 34) patients were collected nationwide in The Netherlands and compared with control samples (n = 16). Histological (semiquantitative) evaluation of the ENS, the network of interstitial cells of Cajal (ICC), and the muscularis propria was performed using hematoxylin and eosin, periodic acid Schiff, and elastic von Gieson staining, and immunohistochemistry with antibodies against HuC/D, calretinin, S100, CD117, α-smooth muscle actin, and desmin. Compared to controls, SB and SCI patients showed neuronal loss and decreased nerve fiber density in the myenteric plexus. Lower nerve fiber density was significantly more often found in patients with severe bowel dysfunction. Other major findings were loss of ICCs around the myenteric plexus and fibrosis in the longitudinal muscle layer. Altered histology of the ENS may explain abnormal intestinal motility in SB and SCI patients. Furthermore, loss of myenteric nerve fibers (including enteric glial cells) may play a major role in the development of severe motility complaints.

Abstract
The current increasing survival of children with severe central nervous system damage has created a major challenge for medical care. Gastrointestinal and nutritional problems in neurologically impaired children have been recently recognized as an integral part of their disease, often leading to growth failure and worsened quality of life for both children and caregivers. Nutritional support is essential for the optimal care of these children. Undernourished handicapped children might not respond properly to intercurrent diseases and suffer unnecessarily. On the other hand, restoring a normal nutritional status results in a better quality of life in many. The easiest and least invasive method to increase energy intake is to improve oral intake. However, oral intake can be maintained as long as there is no risk of aspiration, the child is growing well and the time required to feed the child remains within acceptable limits. When oral intake is unsafe, insufficient or too time consuming, enteral nutrition should be initiated. Damage to the developing central nervous system may result in significant dysfunction in the gastrointestinal tract and is reflected in impairment in oral-motor function, rumination, gastro-oesophageal reflux (GER), with or without aspiration, delayed gastric emptying and constipation. These problems can all potentially contribute to feeding difficulty in disabled children, carrying further challenging long-term management issues.

Abstract
INTRODUCTION Diminished bone mineral density and delayed skeletal maturation are common in children with spastic quadriplegia. AIM The purpose of our study was to evaluate the Bone Mineral Density (BMD) of children with moderate to severe spastic quadriplegia and its relationship with other variables like nutrition and growth. MATERIALS AND METHODS This was a hospital based, cross- sectional, case-control study. Forty-two (28 males, 14 females) children with spastic quadriplegia and 42 (24 males, 18 females) healthy children were included in the study. BMD of cases and control were measured by Dual Energy X-ray Absorptiometry (DEXA). Radiographs of left hand and wrist of cases and controls were taken and bone age was determined. RESULTS BMD values of upper extremity, lower extremity, thoraco-lumbar spine and pelvis in cases were lower than those of controls (p <0.0001). In children with non severe malnutrition, 75% of the cases had lower bone age than chronological age, whereas all cases with severe malnutrition had lower bone age than chronological age. Step wise regression analysis showed that nutritional status independently contributed to lower BMD values but the BMD values did not correlate significantly with the use of anticonvulsant drugs and presence of physical therapy. CONCLUSION Decreased BMD and delayed bone age is prevalent in children with spastic quadriplegia and nutritional status is an important contributing factor.

Abstract
Neurologically impaired (NI) children are at increased risk of malnutrition due to several nutritional and non-nutritional factors. Among the nutritional factors, insufficient dietary intake as a consequence of feeding difficulties is one of the main issues. Feeding problems are frequently secondary to oropharyngeal dysphagia, which usually correlates with the severity of motor impairment and presents in around 90% of preschool children with cerebral palsy (CP) during the first year of life. Other nutritional factors are represented by excessive nutrient losses, often subsequent to gastroesophageal reflux and altered energy metabolism. Among the non-nutritional factors, the type and severity of neurological impairment, ambulatory status, the degree of cognitive impairment, and use of entiepileptic medication altogether concur to determination of nutritional status. With the present review, the current literature is discussed and a practical approach for nutritional assessment in NI children is proposed. Early identification and intervention of nutritional issues of NI children with a multidisciplinary approach is crucial to improve the overall health and quality of life of these complex children.

Abstract
BACKGROUND Thickened milk formulas are used to treat infants with gastroesophageal reflux (GER), but these substances often increase the duration of reflux episodes and worsen symptoms, and they have been associated with diarrhea, constipation, and cough. OBJECTIVES The aims of this study were to determine the efficacy of an antiregurgitation milk formula in the clinical and laboratory setting in infants with proved GER, to investigate any possible adverse events (cough and change in the number of bowel movements or the consistency of stools), and to identify its effects on height and body weight. METHODS Infants with recurrent vomiting and GER who were not responsive to standard treatment were eligible for the study. Infants in the treatment group (group A) were managed for 4 weeks with a specific antiregurgitation milk formula (with cornstarch and an increased amount of casein), and those in the control group (group B) were given a standard milk formula. The number of episodes of vomiting, regurgitation, and cough, as well as the frequency and consistency of stool, height, and body weight were noted at least 10 days before and during the study. A second pH monitoring was performed after 4 weeks in both groups. RESULTS Fifty-six infants (30 boys, 26 girls; mean [SD] age, 3.1 [1.2] months) were included in the study; 30.4% had mild GER; 44.6%, moderate GER; and 25.0%, severe GER. Significantly more infants in group A than in group B (50.0% vs 14.3%, respectively) with mild or moderate GER had normal findings on the second pH monitoring (P<0.05). Changes in the reflux index and in the mean number of vomiting and regurgitation episodes were significantly different between the 2 groups (P<0.05). No significant differences in changes in the mean number of bowel movements and cough events or in the consumption time of the 2 formulas were found between the 2 groups. CONCLUSION Infants with mild or moderate GER can be managed effectively with this antiregurgitation milk formula. Improved clinical and laboratory findings were seen in the majority of infants, and the formula was well tolerated, without adverse events.

Population pharmacokinetics of oral baclofen in pediatric patients with cerebral palsy. J Pediatr 2014; 164:1181-1188.e8. [PMID: 24607242 PMCID: PMC3992203 DOI: 10.1016/j.jpeds.2014.01.029] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2013] [Revised: 11/22/2013] [Accepted: 01/15/2014] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To characterize the population pharmacokinetics (PK) of oral baclofen and assess impact of patient-specific covariates in children with cerebral palsy (CP) in order to support its clinical use. SUBJECTS DESIGN Children (2-17 years of age) with CP received a dose of titrated oral baclofen from 2.5 mg 3 times a day to a maximum tolerated dose of up to 20 mg 4 times a day. PK sampling followed titration of 10-12 weeks. Serial R- and S-baclofen plasma concentrations were measured for up to 16 hours in 49 subjects. Population PK modeling was performed using NONMEM 7.1 (ICON PLC; Ellicott City, Maryland). RESULTS R- and S-baclofen showed identical concentration-time profiles. Both baclofen enantiomers exhibited linear and dose/kg-proportional PK, and no sex differences were observed. Average baclofen terminal half-life was 4.5 hours. A 2-compartment PK model with linear elimination and transit absorption steps adequately described concentration-time profiles of both baclofen enantiomers. The mean population estimate of apparent clearance/F was 0.273 L/h/kg with 33.4% inter-individual variability (IIV), and the apparent volume of distribution (Vss/F) was 1.16 L/kg with 43.9% IIV. Delayed absorption was expressed by a mean transit time of 0.389 hours with 83.7% IIV. Body weight, a possible genetic factor, and age were determinants of apparent clearance in these children. CONCLUSION The PK of oral baclofen exhibited dose-proportionality and were adequately described by a 2-compartment model. Our population PK findings suggest that baclofen dosage can be based on body weight (2 mg/kg per day) and the current baclofen dose escalation strategy is appropriate in the treatment of children with CP older than 2 years of age.

Electrogastrography in adults and children: the strength, pitfalls, and clinical significance of the cutaneous recording of the gastric electrical activity. BIOMED RESEARCH INTERNATIONAL 2013; 2013:282757.

Abstract
Cutaneous electrogastrography (EGG) is a non-invasive technique to record gastric myoelectrical activity from the abdominal surface. Although the recent rapid increase in the development of electrocardiography, EGG still suffers from several limitations. Currently, computer analysis of EGG provides few reliable parameters, such as frequency and the percentage of normal and altered slow wave activity (bradygastria and tachygastria). New EGG hardware and software, along with an appropriate arrangement of abdominal electrodes, could detect the coupling of the gastric slow wave from the EGG. At present, EGG does not diagnose a specific disease, but it puts in evidence stomach motor dysfunctions in different pathological conditions as gastroparesis and functional dyspepsia. Despite the current pitfalls of EGG, a multitasking diagnostic protocol could involve the EGG and the (13)C-breath testing for the evaluation of the gastric emptying time-along with validated gastrointestinal questionnaires and biochemical evaluations of the main gastrointestinal peptides-to identify dyspeptic subgroups. The present review tries to report the state of the art about the pathophysiological background of the gastric electrical activity, the recording and processing methodology of the EGG with particular attention to multichannel recording, and the possible clinical application of the EGG in adult and children.

Abstract
BACKGROUND & AIMS The aim was to study the influence of Nissen fundoplication on rate of gastric emptying and postprandial symptoms in relation to protein source in liquid meals in children with cerebral palsy. METHODS Ten children with cerebral palsy and Nissen fundoplication and ten with cerebral palsy without Nissen fundoplication were studied. Patients had gastrostomy and received two meals, double-blinded, in random order, on separate days. Meals contained a standardised carbohydrate and fat base plus one of two protein modules (Meal A: 100% casein; Meal B: 40% casein/60% whey). The (13)C octanoic acid breath test was used to assess gastric emptying. Postprandial symptoms were recorded. Results are given as median. RESULTS For meal A and B, respectively, time until 50% of the meal had emptied (T1/2) was 110 in the Nissen fundoplication- and 181 min in the non-Nissen fundoplication group, (p = 0.35) and 50 and 85 min (p = 0.25). Seven in the Nissen fundoplication group reported postprandial symptoms to meal B, none in the non-Nissen fundoplication group (p < 0.01). CONCLUSIONS Compared with cerebral palsy-children without Nissen fundoplication, those with Nissen fundoplication have postprandial symptoms more frequently after receiving a rapid emptying meal. Gastric emptying alone, however, does not seem to explain the symptom occurrence. ClinicalTrials.gov: UUSKBK 28200706.

Abstract
OBJECTIVES Children with severe cerebral palsy (CP) commonly have gastrointestinal (GI) dysfunction. Whey-based enteral formulas have been postulated to reduce gastroesophageal reflux (GOR) and accelerate gastric emptying (GE). The authors investigated whether whey-based (vs casein-based) enteral formulas reduce GOR and accelerate GE in children who have severe CP with a gastrostomy and fundoplication. METHODS Thirteen children received a casein-based formula for 1 week and either a 50% whey whole protein (50% WWP) or a 100% whey partially hydrolyzed protein (100% WPHP) formula for 1 week. Reflux episodes, gastric half-emptying time (GE t(1/2)), and reported pain and GI symptoms were measured. RESULTS Whey formulas emptied significantly faster than casein (median [interquartile range (IQR)] GE t(1/2), 33.9 [25.3-166.2] min vs 56.6 [46-191] min; P = .033). Reflux parameters were unchanged. GI symptoms were lower in children who received 50% WWP (visual analog symptom score, median [IQR], 0 [0-11.8]) vs 100% WPHP (13.0 [2.5-24.8]) (P = .035). CONCLUSION This pilot study shows that in children who have severe CP with a gastrostomy and fundoplication, GE of the whey-based enteral formula is significantly faster than casein. The acceleration in GE does not alter GOR frequency, and there appears to be no effect of whey vs casein in reducing acid, nonacid, and total reflux episodes. The results indicate that enteral formula selection may be particularly important for children with severe CP and delayed GE.

Abstract
Cerebral palsy (CP) is the most common physical disability in early childhood. The worldwide prevalence of CP is approximately 2-2.5 per 1,000 live births. It has been clinically defined as a group of motor, cognitive, and perceptive impairments secondary to a non-progressive defect or lesion of the developing brain. Children with CP can have swallowing problems with severe drooling as one of the consequences. Malnutrition and recurrent aspiration pneumonia can increase the risk of morbidity and mortality. Early attention should be given to dysphagia and excessive drooling and their substantial contribution to the burden of a child with CP and his/her family. This review displays the important functional and anatomical issues related to swallowing problems in children with CP based on relevant literature and expert opinion. Furthermore, based on our experience, we describe a plan for approach of investigation and treatment of swallowing problems in cerebral palsy.

Abstract
Aim: To study the gastric emptying 30 days after laparoscopic Nissen fundoplication (NF) in gastroesophageal reflux. Materials and Methods: Three patients were evaluated with 13C-acetate breath test (ABT) performed pre and post-NF. The liquid test meal consisted of Racol™ mixed with 13C-acetate. Results: In the patient without neurological impairment (NI), the preoperative t½ex and t lag were 0.900 and 0.510 hours, respectively. The postoperative t½ex and t lag were 0.959 and 0.586 hours, respectively. In one patient with NI, the preoperative t½ex and t lag were 1.828 and 1.092 hours, respectively. The postoperative t½ex and t lag were 2.081 and 1.025 hours, respectively. In the other patient with NI, the preoperative t½ex and t lag were 2.110 and 0.980 hours, respectively. The postoperative t½ex and t lag were 1.118 and 0.415 hours, respectively. Conclusions: Our findings suggest that 13C-ABT parameters did not worsen in any of the children after laparoscopic NF.

Abstract
BACKGROUND & AIM Dysmotility, nausea and vomiting are common among children with cerebral palsy. This study aimed to evaluate influence of protein composition on rate of gastric emptying and study the relation between gastric emptying and postprandial gastrointestinal symptoms. METHODS 15 children with cerebral palsy, using gastrostomy, received four liquid test meals on separate days in random order. The meals contained a standard carbohydrate and fat base plus one of four protein modules (100% casein (A), hydrolysed whey (B), amino acids (C) and 40% casein/60% whey (D)) with a total energy of 1 kcal/ml. The (13)C octanoic acid breath test was applied to assess gastric emptying. RESULTS When comparing half emptying time (T(1/2)) of the fast emptying meals (meal B, C and D) with the slowest emptying meal (meal A), more rapid emptying was demonstrated for meal D (p < 0.001). For meal D, emptying was significantly faster in children with postprandial symptoms than in those without (p < 0.01). CONCLUSION In children with cerebral palsy using gastrostomy, gastric emptying is influenced by type of protein in the meal. The present results also suggest that there is a relation between rapid gastric emptying and postprandial gastrointestinal symptoms. CLINICALTRIALS.GOV: UUSKBK 28200706.

Abstract
Gastrointestinal motility disorders can develop in neurologically impaired children and those with congenital malformations of the gut. It is characterized by moderate to severe abdominal pain, vomiting, and failure to thrive. Antral dysmotility after fundoplication and increased sympathetic over activity are 2 factors associated with this condition that make it difficult to treat. This paper proposes a management strategy using metoclopramide, celiac plexus blockade, and thoracic splanchnectomy. It reviews our experience with 11 patients.

Abstract
The case of a 15 year old female born with multiple anomalies, who subsequently developed severe gastro-intestinal dysmotility is discussed. Motility disorders are often seen in neurologically impaired children, those with a history of gastro-oesophageal reflux disease (GORD), and congenital malformations of the gut. It is characterized by abdominal pain, vomiting and failure to thrive. Once this condition develops, it is difficult to treat. This girl failed to improve with conventional treatment including repeated fundoplication. We hypothesised that her symptoms maybe due to antral dysmotility and sympathetic over-activity. She underwent celiac plexus blockade which was immediately curative but temporary and therefore underwent minimally invasive thoracic splanchnectomy. She continues to be asymptomatic. We discuss the relevant anatomy and management protocol which should be considered in such difficult cases.

Abstract
The enteric nervous system is an integrative brain with collection of neurons in the gastrointestinal tract which is capable of functioning independently of the central nervous system (CNS). The enteric nervous system modulates motility, secretions, microcirculation, immune and inflammatory responses of the gastrointestinal tract. Dysphagia, feeding intolerance, gastroesophageal reflux, abdominal pain, and constipation are few of the medical problems frequently encountered in children with developmental disabilities. Alteration in bowel motility have been described in most of these disorders and can results from a primary defect in the enteric neurons or central modulation. The development and physiology of the enteric nervous system is discussed along with the basic mechanisms involved in controlling various functions of the gastrointestinal tract. The intestinal motility, neurogastric reflexes, and brain perception of visceral hyperalgesia are also discussed. This will help better understand the pathophysiology of these disorders in children with developmental disabilities.

Abstract
PURPOSE To evaluate the effect of hypoxic-ischemic brain injury over the gastric emptying of liquids in rats. METHODS Fifty-two Wistar rats aged six weeks and weighing between 100 g and 150 g were divided in three groups. A Control group (C), a Sham group (S) undergoing sham procedure, and a Hypoxic-ischemic group (HI) consisting of 18 animals undergoing surgical ligature of the left carotid artery and exposure to hypoxic environment for three hours. Half of the animals were studied in the third day post-HI procedure (Early) and nine in the 14th day post-HI procedure (Late). Gastric emptying was evaluated by an infusion technique using fenolsulftalein as a marker. RESULTS After the HI procedure, all animals displayed left eyelid ptosis, and six animals showed minor sideway gait. Histological examination confirmed de brain injury in all animals from the HI group. There was no statistical significant difference among the mean gastric retention values of the three groups neither in the Early nor in the Late evaluation. CONCLUSION Isolated HI brain injury was not associated with delayed gastric emptying.

Abstract
OBJECT The purpose of this study was to investigate the effect of N-methyl-d-aspartate (NMDA) receptor antagonist on esophageal and gastric smooth muscle reactivity in a rat hydrocephalus model. MATERIAL AND METHODS Hydrocephalus was induced in rats by injection of kaolin into the cisterna magna. Two weeks after the procedure, memantine (20 mg/kg per day, 2 weeks) was given to rats with hydrocephalus in the memantine group (MG). The rest of the rats with hydrocephalus received serum physiologic (hydrocephalus group, HG). The control group (nonhydrocephalic rats, CG) was sham operated. The fourth group consisted of nonhydrocephalic rats with treated memantine (memantine control group, MC). Contractile (KCl, carbachol) and relaxant (isoprenaline, papaverine) esophageal and gastric smooth muscle reactivity were determined by in vitro muscle technique. RESULTS No significant difference was found in the KCl (nonreceptor-mediated)-induced esophageal smooth muscle reactivity among the groups. Carbachol (receptor-mediated)-induced smooth muscle reactivity significantly decreased in HG compared to other groups. The isoprenaline (receptor-mediated)-induced smooth muscle reactivity significantly decreased in HG compared to other groups. No significant difference was found in smooth muscle reactivity to papaverine (nonreceptor-mediated) among the groups. Gastric smooth muscle reactivity to KCl significantly increased in HG compared to other groups. Also, KCl-induced smooth muscle reactivity significantly increased in MG compared to CG and MC. Carbachol-induced smooth muscle reactivity significantly decreased in HG compared to MG, CG, and MC. No significant difference was observed in isoprenaline- and papaverine-induced smooth muscle reactivity among the groups. CONCLUSION Our findings suggest that memantine may influence esophageal and gastric smooth muscle reactivity in hydrocephalus.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) occurs when stomach acid frequently backs up (or refluxes) into the gullet (or esophagus), and it has serious consequences for the quality of life. Usually this is felt as heartburn. Because severely mentally retarded people usually do not utter complaints of heartburn, it requires a high index of suspicion to discover possible GERD. Therefore it is relevant for care professionals such as nurses to have knowledge of those with a higher risk of GERD and of the possible manifestations of GERD. METHODS Using a predefined search method, electronic databases were searched for studies relating the presence of symptoms to the presence of GERD. Relevant data were extracted and the methodological quality of the studies assessed. The results of the included studies were synthesized and conclusions about the level of evidence were drawn. RESULTS Nineteen studies were found relating symptoms to the presence of GERD. Only four were of good methodological quality. The studies were very diverse concerning the studied population, the study method, and the kind of symptoms examined. This makes it difficult to synthesize the results of the studies. There is evidence that patients with cerebral palsy, patients using anticonvulsive drugs, and those with an IQ lower than 35 more frequently have GERD. There is also evidence that vomiting, rumination and hematemesis are associated with a higher risk of the presence of GERD, whereas there is no clear scientific evidence that particular behavior symptoms are indicative for GERD. CONCLUSION The possible manifestations of GERD are many and varied. A guideline will be made for care professionals to aid systematic observation of possible manifestations of GERD.

Abstract
BACKGROUND The benefits of surgery for gastroesophageal reflux disease (GERD) in infants and children have been questioned in the recent literature. The goal of this review was to determine the best current practice for the diagnosis and management of this disease. METHODS The literature was reviewed for all recent English language publications on the management of GERD in 8- to 10-year-old patients. RESULTS In infants and children, GERD has multiple etiologies, and an understanding of these is important for determining which patients are the best surgical candidates. Proton pump inhibitors (PPIs) have become the mainstay of current treatment for primary GERD. Although laparoscopic surgery appears to be better than open surgery, there remains some morbidity and complications that careful patient selection can minimize. CONCLUSION Surgery for GERD should be performed only after failure of medical management or for specific problems that mandate it.

Abstract
OBJECTIVES Gastroesophageal reflux (GER) may underlie respiratory manifestations via vagally mediated airway hyperresponsiveness or microaspiration, and intraesophageal pH monitoring is generally used to identify GER in patients with such manifestations. We aimed to establish the frequency of retrograde pulmonary aspiration in patients with unexplained respiratory manifestations. METHODS Fifty-one patients with refractory respiratory symptoms (cough, n = 18; pneumonia, n = 14; apnea, n = 8; asthma, n = 7; and laryngitis, n = 4) were prospectively evaluated. They underwent 24-h intraesophageal pH monitoring and gastroesophageal 99Tc scintigraphy with lung scan 18 to 20 h after the test meal. RESULTS Thirteen of 51 patients (25.5%) had abnormal intraesophageal pH study results (mean reflux index, 11.3%; range, 6.5 to 50%); and in 25 of 51 patients (49%), overnight scintigraphy showed pulmonary aspiration. Nineteen of these 25 patients had entirely normal pH study results, whereas 6 of 13 patients with abnormal pH study results had aspiration. Pulmonary aspiration was demonstrated in all patients with apnea and 61.5% of patients with recurrent pneumonia. Nine of 25 patients (36%) with aspiration had histologic evidence of esophagitis, whereas histologic esophagitis was present in 5 of 13 patients (38.4%) with pathologic GER as shown by intraesophageal pH monitoring. CONCLUSIONS Pulmonary aspiration as demonstrated by overnight scintigraphy is common in children with unexplained and refractory respiratory manifestations, suggesting that GER could be the underlying cause of these manifestations. Since only a few children with chronic or recurrent respiratory symptoms have a pathologic gastroesophageal acid reflux, a normal intraesophageal pH study result does not rule out GER in these children.

Abstract
Undernutrition, growth failure, overweight, micronutrient deficiencies, and osteopenia are nutritional comorbidities that affect the neurologically impaired child. Monitoring neurologically impaired children for nutritional comorbidities is an integral part of their care. Early involvement by a multidisciplinary team of physicians, nurses, dieticians, occupational and speech therapists, psychologists, and social workers is essential to prevent the adverse outcomes associated with feeding difficulties and poor nutritional status. Careful evaluation and monitoring of severely disabled children for nutritional problems are warranted because of the increased risk of nutrition-related morbidity and mortality.

Abstract
Children with a variety of genetic, metabolic, and neurologic disorders can suffer from severe feeding intolerance that is unresponsive to medical, surgical, and nutritional therapy. Developmentally disabled tube-fed children with severe upper gastrointestinal symptoms that persisted after fundoplication who were unresponsive to all medical, surgical, and nutritional interventions underwent a thorough gastrointestinal evaluation, including gastroscopy, pH-metry, upper gastrointestinal barium series, and gastric emptying studies. They were placed on a low-fat diet, and the symptoms before and after the diet were compared. The patients were then rechallenged with incremental increases in fat until the symptoms recurred or the patients reached their former fat concentration. Six children meeting the study criteria were evaluated. Four of these patients had a significant improvement in symptoms, oral intake and feeding tolerance with a decrease in fat intake, and relapse of symptoms when fat calories were increased. Improvement occurred in children who had been intolerant to duodenal feeding. We were subsequently able to wean two children from tube feeding. Dietary fat can provoke upper gastrointestinal symptoms in children with gastric and intestinal dysmotility. Short-term manipulation of dietary fat intake can improve tolerance to feeding.

Abstract
BACKGROUND AND AIMS Procedures for diagnosis of gastrointestinal (GI) symptoms in newborn and preterm infants should preferably be non-invasive. This study evaluates the usability of electrogastrography (EGG), a non-invasive, cutaneous recording of the gastric myoelectrical activity in newborn infants. METHOD Sixty-two randomly selected infants [27 girls and 35 boys with median gestational age of 36 weeks (range 29-42)] divided into six groups (by postconceptional age) were studied on median day 5 (range 1-24) after birth. None had GI symptoms. EGG recordings were made by Digitrapper EGG recording system. RESULTS Findings were highly dispersed and without statistical difference both between pre- and postprandial periods and among the six study groups. Dominant frequency of 2.5 cycles per minute was found for 57 of 62 infants, with distribution of normal, bradygastric and tachygastric slow wave frequency uniformly dispersed around 50, 35 and 15% respectively. CONCLUSION We find EGG unsuitable for clinical use because of significant variation in gastric slow wave frequency in normal term and preterm infants without GI symptoms.

Abstract
BACKGROUND/PURPOSE Gastroesophageal reflux is common in children with severe neurological impairment. Fundoplication may produce symptomatic improvement but has a high failure rate. Esophagogastric dissociation (EGD) is an alternative procedure for treatment of gastroesophageal reflux. The aim of this study is to evaluate the results of EGD in our institution and compare them with a neurologically matched group of children who had Nissen fundoplication. METHODS Twenty consecutive patients who had EGD were retrospectively evaluated and the results were compared with a neurologically matched group of 20 consecutive patients who had Nissen fundoplication. RESULTS Twenty patients had EGD, 17 as a primary procedure. There was no operative mortality but 5 have died of other causes. Resolution of reflux-associated symptoms occurred in all patients. Of the 15 survivors, 5 remain on antireflux medication. Twenty patients had fundoplication. There was no operative mortality, but 8 patients have died of other causes. Failure occurred in 5 patients necessitating further surgery. Of the 10 unreoperated survivors, 6 remain on antireflux medication. CONCLUSIONS Esophagogastric dissociation is an effective antireflux procedure when compared with fundoplication. It has a lower failure rate. We recommend EGD as a primary procedure in selected children with severe neurological impairment.

Abstract
In children with medically refractory gastroesophageal reflux disease (GERD), fundoplication is effective and safe. However, in a subset of patients, gastrointestinal dysfunction occurs postoperatively. Symptoms include chest pain, persistent dysphagia in 5%, gas bloat in 2% to 4%, diarrhea in up to 20%, and dumping syndrome in up to 30%. Symptoms are often nonspecific, arising from recurrent or persistent GERD, anatomic complications such as disrupted or herniated wrap, functional disturbances such as rapid gastric emptying or altered gastric accommodation, or alternative diagnoses such as cyclic vomiting syndrome or food allergy. Detailed investigation, including various combinations of pHmetry, videofluoroscopy, endoscopy, motility studies, and dumping provocation testing, may be required to clarify pathophysiology and guide management.

Abstract
Background Dysphagia and feeding intolerance are common in neurologically handicapped children. The aim is to determine the etiologies of feeding intolerance in neurologically handicapped children who are intolerant of tube feedings. Methods Eighteen neurologically handicapped children, followed in the Tube Feeding Clinic at the Children's Hospital of Wisconsin who were intolerant of gastrostomy feedings. The charts of these 18 patients were reviewed. Past medical history, diagnoses, history of fundoplication and results of various tests of gastrointestinal function including barium contrast radiography, endoscopy and antroduodenal manometry were documented. Results Five of 11 children had abnormal barium upper gastrointestinal series. Seven of 14 had abnormal liquid phase gastric emptying tests. Two of 16 had esophagitis on endoscopy. All 18 children had abnormal antroduodenal motility. Conclusions In neurologically handicapped children foregut dysmotility may be more common than is generally recognized and can explain many of the upper gastrointestinal symptoms in neurologically handicapped children.

Abstract
Gastric emptying time is considered a factor in the increased frequency of gastroesophageal reflux in children with cerebral palsy. It is unknown if emptying time influences the severity of reflux. In this study, 76 cerebral palsy patients with reflux indicative symptoms were investigated by 24-hour pH monitoring. Reflux complications were also studied. Emptying time in children with reflux was investigated using gastric scintigraphy. Twenty-eight children with resistant asthma scanned for pulmonary aspiration were studied as control subjects for emptying time. Reflux was diagnosed in 51.3%; it was severe in 53.8%, moderate in 38.5%, and mild in 7.7%. Occurrence of reflux did not differ significantly among different forms of cerebral palsy or between males and females. The most frequent complications in reflux-positive patients were iron deficiency (51.3%), anemia (41.0%), malnutrition (33.3%), recurrent upper respiratory tract infections (28.2%), and low body weight (28.2%). Patients without reflux had less frequent complications. Gastric emptying time measured by gastric scintigraphy in 28 patients with reflux manifested no difference in comparison to the control group (P > 0.05). No relationship was found between emptying time and reflux severity (P > 0.05). In conclusion, reflux (moderate or severe) is common in children with cerebral palsy, frequently leading to complications but no delayed emptying time. The patients described in this report had no delayed emptying time. There was also no relationship between emptying time and severity of reflux.

Abstract
BACKGROUND An association between hydrocephalus and gastroesophageal motor abnormalities that cause gastroesophageal reflux (GER) is well known. Our aim was to investigate hydrocephalus-induced alterations in esophageal and gastric smooth muscle reactivity and their modulation by pharmacological interventions in the rat model. MATERIALS AND METHODS Hydrocephalus was induced in infantile rats by injection of kaolin into the cisterna magna. Hydrocephalic and sham-operated rats were exsanguinated 2 weeks after surgery. Esophageal and gastric fundus smooth muscle strips were studied in vitro for their contractile and relaxant response to receptor activation in the organ chambers set up. Additionally, esophageal and gastric tissue specimens were examined histologically for GER-induced changes. RESULTS No histological evidence of esophageal and gastric changes reflecting GER was observed in the specimens of the control and hydrocephalus-induced rats. Maximum contractile responses of esophageal and gastric fundus smooth muscle to KCl and muscarinic receptor agonist carbachol were increased in the hydrocephalic groups compared with the control groups. These changes were statistically significant. Relaxant responses to beta adrenoceptor agonist isoprenaline were similar in the esophageal muscle strips of both hydrocephalic groups and the control groups. However, isoprenaline-induced relaxant responses of the gastric fundus muscle strips in the hydrocephalus-induced groups were significantly decreased as compared with the control groups. The relaxant responses to papaverine in the esophageal and gastric fundus smooth muscle strips were similar in the two groups. CONCLUSIONS Our study revealed alterations of receptor-dependent and receptor-independent foregut smooth muscle reactivity in the hydrocephalus-induced rat pups. Therefore, we suggest that impaired smooth muscle reactivity at least in part may contribute to abnormalities of foregut motor function seen in patients with hydrocephalus.

Abstract
BACKGROUND Gastrointestinal symptoms have been reported in association with myoelectrical dysrhythmia, where different types of gastric electrical activity have been described. These types of gastric myoelectrical activity and dysrhythmia can be measured by electrogastrography using cutaneous electrodes. Epigastric impedance is a non-invasive method used to study gastric emptying time and gastric phasic activity. At present no study of gastric dysrhythmia, measured with epigastric impedance, has been presented, and the purpose of the present study was to investigate gastric rhythms by means of impedance gastrography in control infants, compared to infants with different gastrointestinal diseases, before and after treatment of their disease. METHOD 21 patients (age 0-2 months) and 40 healthy infants (age 0-2 months) were investigated. The patients suffered from partial or total intestinal obstruction, necrotizing enterocolitis or pyloric stenosis.All infants were fasting and studied during periods of at least one hour. The patients were examined in the acute state and after treatment when possible. RESULTS A pathologic result was found in 90% of the patients. A persistent phasic activity pattern was found in 19 of the 21 patients, high frequency phasic activity in 11 of the 21 patients. Short-term phasic activity was only found in 13 out of 40 of the normal infants (32.5%). CONCLUSION Using epigastric impedance we found that infants with partial or total intestinal obstruction had gastric phasic activity, which was not found in the control infants. The origin of the gastric phasic activity patterns is unknown, but they may be related to electrical control activity.

Abstract
The objective of this document is to present the consensus opinion of the American Motility Society Clinical GI Motility Testing Task Force on the performance and clinical utility of electrogastrography (EGG). EGG is a non-invasive means of recording human gastric myoelectrical activity or slow waves from cutaneous leads placed over the stomach. In healthy volunteers, EGG tracings exhibit sinusoidal waveforms with a predominant frequency of 3 cycles per minute (cpm). Clinical studies have shown good correlation of these cutaneous recordings with those acquired from serosally implanted electrodes. The amplitude of the EGG waveform increases with ingestion of caloric or non-caloric meals. Some patients with nausea, vomiting, or other dyspeptic symptoms exhibit EGG rhythm disturbances or blunting of meal-evoked EGG signal amplitude increases. These abnormalities correlate to some degree with delayed gastric emptying of solids. In selected patients, EGG may be complementary to gastric emptying testing. To date, no therapies have convincingly demonstrated in controlled studies that correcting abnormalities detected by EGG improves upper gastrointestinal symptoms. Proposed clinical indications for performance of EGG in patients with unexplained nausea, vomiting and dyspeptic symptoms must be validated by prospective controlled investigations.

Abstract
PURPOSE to describe the patterns of the gastric myoelectrical activity, pre-and postprandially, in clinically stable neonates of different gestational ages, during their first two weeks of life by means of Electrogastrography. PATIENTS AND METHODS Electrogastrography was recorded in forty-five clinically stable neonates of different gestational ages (group I: 15 neonates of > 37 weeks, group II: 15 premature neonates of 32-37 weeks; Group III: 15 premature neonates of 28-31 weeks) receiving intermittent enteral feedings during their first two weeks of life. Electrogastrography recordings were performed for 1 hour pre-and postprandially. The Electrogastrography signal was recorded using the portable MicroDigitrapper Electrogastrography recording device and after motion artifacts were deleted, the remaining Electrogastrography data were submitted to quantitative analysis based on the "Running Spectrum Analysis". RESULTS The percentages of normogastria, pre-and postprandially were greater than the percentages of gastric dysrythmias in all three studied groups. Furthermore, all neonates had the mean values of the Electrogastrography dominant frequency predominantly within the normogastria range, in both periods analyzed. There were no significant differences in the relative change of the Electrogastrography dominant power among the groups. CONCLUSION This study demonstrates that the Electrogastrography patterns are similar between premature and full term neonates during the pre-and postprandial periods. The results of this study also indicate that the gastric myoelectrical activity in premature and full term neonates is immature, as compared to that described for older neonates, children and adults.

Abstract
Gastroesophageal reflux is a physiological phenomenon, occurring with different severity and duration in different individuals. Reflux occurs when this normal event results in the occurrence of symptoms/signs or complications. The pathophysiology of gastroesophageal reflux is complex and diverse, since it is influenced by factors that are genetic, environmental (e.g., diet smoking), anatomic, hormonal, and neurogenic. However, many mechanisms remain incompletely understood. Future research should focus on a better understanding of the physiology of the upper and lower esophageal sphincters, and of gastric motility. The afferent and efferent neural pathways and neuropharmacologic mediators of transient lower esophageal sphincter relaxations and gastric dysmotility require further study. The role of anatomic malformations such as hiatal hernia in children has been underestimated. While therapeutic possibilities are greater in number and largely improved, the outcomes of some treatments are far from satisfactory in many cases. In addition to development of new forms of treatment, research should address better use of currently available medical and surgical treatments.

Abstract
Electrogastrography (EGG), the measurement of gastric pacemeaker activity by means of surface electrodes, provides a noninvasive technique to detect and quantify the characteristics of the gastric slow wave. With a predominant frequency of three cycles per minute, the activity of the specialized cells responsible for this pacing, the interstitial cells of Cajal, is crucial in providing the underlying electrophysiologic changes that enable coordinated smooth muscle contraction and synchronized peristalsis. Advances in electronics and software to define frequency distribution, stability of the signal, postprandial changes, and other parameters have contributed to more widespread interest in EGG and its application to the investigation of functional gastrointestinal disturbances. Definition of pediatric norms and postnatal changes in the EGG of premature infants has provided the foundation for further studies investigating correlative changes with such important functions as gastric emptying and motility. The EGG remains a promising diagnostic tool. Future studies will help define its usefulness in identifying abnormal functions of the interstitial cells of Cajal.

Abstract
We describe a previously healthy boy who developed intestinal pseudo-obstruction following an episode of gastroenteritis at age 2 years. At presentation, the patient had mildly raised erythrocyte sedimentation rate and C-reactive protein level, and elevated antineutrophil cytoplasmic antibodies, antinuclear anti-DNA, and anti-smooth muscle antibodies. His electrogastrography was myopathic with no dominant frequency. First full-thickness intestinal biopsies showed a T lymphocytic myositis, particularly in the circular muscle. Steroid therapy resulted in clinical remission; cessation of steroids, in relapse. Further full-thickness biopsies showed an initial reduction in alpha-smooth muscle actin immunostaining in circular muscle myocytes and later atrophy and disappearance of many myocytes. Vascular and the remaining enteric smooth muscle cells showed HLA-DR and intercellular adhesion molecule 1 expression. These observations demonstrate the ability of enteric myocytes to take part in an inflammatory response and to change their phenotype, allowing them to act as antigen-presenting cells and to activate T cells. This and possible cytokine production by the myocytes play a role in their own destruction. This process responded to immunosuppressive therapy.

BACKGROUND Regurgitation and vomiting are common manifestations of cow's milk protein allergy (CMPA) in infants and are usually ascribed to gastroesophageal reflux (GER). Gastric anaphylaxis can induce antral dysmotility in the rat, and therefore the hypothesis for the current study was that cow's milk in sensitized infants may impair antral motility, thereby promoting GER and reflex vomiting. METHODS Seven vomiting infants with CMPA and nine with primary GER underwent a challenge with cow's milk formula. Electrogastrography (EGG) was used to measure the spectral frequency (bradygastria = 1.5-2.4 cycles per minute [cpm], normogastria = 2.5-3.9 cpm, tachygastria = 4.0-9.0 cpm) and the postprandial-to-fasting power ratio of gastric electrical activity, whereas gastric half-emptying time (T1/2) was measured by electrical impedance tomography (EIT). RESULTS In CMPA and GER, respectively, during fasting, the frequency distribution (mean +/- SD) of the EGG was as follows: normogastria 47.9%+/-12.5% versus 52.2%+/-9.8%, bradygastria 24.1%+/-5.7% versus 22.8%+/-8.3%, and tachygastria 28.0% 8.5% versus 25.0% 8.3%. In contrast, after the cow's milk challenge, the difference between the two groups was statistically significant: normogastria 33.1%+/-8.8% versus 70.6%+/-8.6% (P < 0.0001). bradygastria 38.0%+/-15.5% versus 15.7%+/-5.2% (P = 0.002), and tachygastria 28.9%+/-10.6% versus 13.4%+/-4.6% (P = 0.001. The postprandial/ fasting power ratio (mean +/- SD) was 3.2+/-1.9 in CMPA and 8.1+/-2.1 in GER (P < 0.0001). Gastric T1/2 (mean +/- SD) of the cow's milk meal was 89.0+/-26.3 minutes versus 54.0+/-12.6 minutes (P = 0.003). In infants with GER all EGG parameters and gastric T1/2 were similar to that in 10 healthy control infants. CONCLUSIONS In sensitized infants, cow's milk induces severe gastric dysrhythmia and delayed gastric emptying, which in turn may exacerbate GER and induce reflex vomiting. Electrogastrography and EIT can be useful in the assessment of vomiting, GER, and CMPA in infants.
