Gastroesophageal reflux in children

Taking Care of Preterm Infants: Outpatient Considerations

In recent decades, the number of pre-term infants born each year has been on the rise as mortality rates decline with improvements in technology and medical care. As a result, many preterm infants are successfully discharged from the neonatal intensive care unit (NICU). However, with prematurity comes the increased risk of ongoing health and development needs. Special attention must be given to certain chronic conditions by the outpatient provider, including growth and nutrition; gastroesophageal reflux; immunizations; vision and hearing impairments; chronic lung diseases, including bronchopulmonary dysplasia and pulmonary hypertension; and neurodevelopmental outcomes. This article will detail some of these topics to better inform the primary care provider of appropriate strategies to manage these chronic conditions and sequalae on NICU discharge.

GERD in Neonates and Pediatrics: Use of Omeprazole

Gastroesophageal reflux is a common disorder found in infants and children. Treatment modalities include conservative measures, medications, and surgery. Histamine2 receptor antagonists alone or in combination with prokinetic agents are the first-line medical options, but the addition of prokinetic agents or a change to proton pump inhibitors is reasonable. Corrective fundoplication is reserved as the last-line treatment strategy. The use of proton pump inhibitors such as omeprazole for acid suppression has been studied in children, and a stable, extemporaneous formulation can be prepared. Despite limited data in pediatrics, omeprazole appears to be safe and effective for treating reflux and for decreasing the need for fundoplication.

Pathophysiology of aerodigestive pulmonary disorders in the neonate

No test can provide a definitive diagnosis of aerodigestive disease. When interpreting tests, one should weigh the benefits and weaknesses of different technologies and methods, scientific appropriateness of the testing conditions, clinicopathologic correlation, and pharmacologic approaches. Gastroesophageal reflux disease (GERD) symptoms and airway symptoms can coexist, and they cannot be distinguished without specific testing and direct observations. Important aerodigestive disorders include dysphagia, GERD, and aggravation of airway injury due to malfunctions of swallowing or airway protection mechanisms. Objective evaluation of aerodigestive reflexes and symptom correlation may provide support for evidence-based personalized management of feeding and airway protection strategies.

Clinical Perspectives on Esophageal Disorders in Infants

Esophageal pathologies are complex and lend themselves to multivariable analysis before a definitive diagnosis can be considered. It is imperative that the clinician establish a methodology for selecting the appropriate technological assessment within scientific testing parameters to establish optimal clinicopathological presentation and determine best practice for patient care.

Gastroesophageal reflux scintigraphy: interpretation methods and inter-reader agreement

BACKGROUND

Scintigraphic imaging is a useful screening tool for patients with suspected gastroesophageal reflux. New scintigraphic interpretation methods have recently been introduced. This study was undertaken to evaluate the efficiency of various scintigraphic interpretation methods in the detection of gastroesophageal reflux and to measure their influence on inter-reader agreement.

METHODS

Scintigraphic images of 49 children with suspected gastroesophageal reflux were interpreted by three different methods: visual interpretation, time activity curves, and condensed images. The readings were performed by three specialists and a resident. The discordant results were resolved by a consensus reading done together by all interpreters based on the three different methods. The gastroesophageal refluxes were grouped according to their number, location and intensity.

RESULTS

Gastroesophageal reflux scintigraphy revealed 22 patients with negative results and 27 with positive results. The sensitivity, positive predictive value and specificity for each of the three specialists vs. the resident were 96%, 96% and 81% vs. 96%; 93%, 90% and 96% vs. 81%; and 90%, 86%, and 95% vs. 73%, respectively. The mean inter-observer reproducibility (κ value) was 0.910 for visual interpretation, 0.652 for time activity curves and 0.789 for condensed images. Twenty-seven percent of the results were discordant and most of these refluxes were of low grade (92%), low intensity (77%) and localization in the distal esophagus (54%).

CONCLUSION

Gastroesophageal scintigraphy is a useful tool for detecting patients with suspected reflux, and visual interpretation is better than the other two methods in terms of accuracy and inter-observer reproducibility.

Discerning differences: gastroesophageal reflux and gastroesophageal reflux disease in infants

Gastroesophageal reflux (GER) is a frequently encountered problem in infancy; it commonly resolves spontaneously by 12 months of age. Caregivers are challenged to discriminate between physiologic GER and the much less common and more serious condition of pathologic gastroesophageal reflux disease (GERD). Pathologic GERD may require more extensive clinical evaluation and necessitate treatment. GERD may be primary or secondary; secondary GERD is associated with a number of genetic syndromes, chromosomal abnormalities, birth defects, or a host of neurologic conditions frequently seen in the newborn intensive care unit. This article reviews the unique anatomic, physiologic, developmental, and nutritional vulnerabilities of infants that make them susceptible to GER and GERD. The North American Society of Pediatric Gastroenterology and Nutrition have recently developed a comprehensive evidence-based clinical practice guideline that structures the diagnostic approach and treatment option in infants with suspected and confirmed GERD. These guidelines provide clear definitions of GER and GERD to aid the clinician in distinguishing between the 2 conditions. They emphasize the use of history and physical examination and discuss the indications for the use of other diagnostic procedures, such as upper gastrointestinal studies, nuclear medicine scintiscan, esophagogastroduodenoscopy with biopsy, and esophageal pH probe monitoring. Management of GERD begins with a nonpharmacologic approach; the emphasis is on positioning, a trial of a hypoallergenic formula, and thickening of feedings. When these measures fail to control symptoms, a trial of either histamine(2) antagonists or a proton pump inhibitor may be indicated. Finally, surgical treatment may be needed if all other management measures fail. New sleep recommendations for infants with GERD are now consistent with the American Academy of Pediatrics' standard recommendations. Prone sleep positioning is only considered in unusual cases, where the risk of death and complications from GERD outweighs the potential increased risk of sudden infant death syndrome (SIDS). The nursing care of infants with GER and GERD, as well as relevant issues for parent education and support, are reviewed and are essential elements in managing this common condition.

Chiari I malformation in the very young child: the spectrum of presentations and experience in 31 children under age 6 years

INTRODUCTION

The entity of hindbrain herniation without myelodysplasia in the very young child has been poorly described. A retrospective analysis of children diagnosed with Chiari I malformation (CM I) before their sixth birthday is presented.

METHODS

Since 1985, 31 children with CM I (0.3-5.8) years of age have been diagnosed at University of Iowa Hospitals and Clinics. Their records were reviewed for presenting symptoms, signs, radiographic findings, treatment, complications, and outcome.

RESULTS

The average age at diagnosis was 3.3 years. Sixteen patients were under age 3. Chief presenting complaints included impaired oropharyngeal function (35%), scoliosis (23%), headache or neck pain (23%), sensory disturbance (6%), weakness (3%), and other (10%). Sixty-nine percent of children under age 3 had abnormal oropharyngeal function. Three patients under age 3 (19%) had undergone fundoplication and/or gastrostomy before diagnosis of CM I. Common physical findings included abnormal tendon reflexes (68%), scoliosis (26%), abnormal gag reflex (13%), and normal examination (13%). Vocal cord dysfunction (26%, all under age 3) and syringohydromyelia (52%) were also seen. Twenty-five patients were treated surgically at our institution with posterior fossa decompression, duraplasty, and cerebellar tonsillar shrinkage. Three patients were lost to follow-up. Ninety-one percent of patients reported improved symptomatology at last follow-up (mean: 3.9 years). Three patients required reoperation for recurrence of symptoms. Syringomyelia improved in all patients. Scoliosis resolved in 2 of 8 patients, improved in 5, and stabilized in 1. There was no permanent morbidity from surgery.

DISCUSSION

We show that children with Chiari I abnormality are very likely to present with oropharyngeal dysfunction if under age 3, and either scoliosis or headache or neck pain worsened by valsalva if age 3 to 5. These symptoms are very likely to improve after Chiari decompression, which can be done with low morbidity.

CONCLUSIONS

Very young children presenting with oropharyngeal dysfunction, pain worsened by valsalva, or scoliosis should prompt the clinician to consider CM I as a possible cause.

Severe non-obstructive sleep disturbance as an initial presentation of gastroesophageal reflux disease

A 2.5-year-old child presented with a sleep disturbance initially diagnosed as a behavioral problem. The child had several atypical symptoms of gastroesophageal reflux disease (GERD). The sleep disturbance resolved quickly after treatment of GERD. GERD is a disease with protean manifestations which is becoming of greater interest to the pediatric otolaryngologist. We discuss diagnosis of this entity.

The otolaryngologic manifestations of gastroesophageal reflux: when is a pH study indicated?

PURPOSE

The aim of this study was to evaluate the pertinence of pH studies for persistent ear, nose, and throat (ENT) symptoms and their eventual relationship to gastroesophageal reflux (GER).

METHODS

Retrospective analysis was performed of age, reason for referral, pH study, treatment, and follow-up of patients with ENT symptoms suspected to have GER.

RESULTS

Of 3,000 esophageal pH studies performed over 16 years, 105 children were referred for ENT symptoms by an otorhinolaryngologist to rule out GER. Mean age was 33 months; 65% were boys. Reasons for referral included (number and mean age): stridor (n = 31, 8 months), laryngomalacia (n = 18, 13 months), recurrent otitis (n = 12, 42 months), laryngitis (n = 16, 50 months), dysphonia (n = 14, 59 months), laryngeal papillomatosis (n = 8, 62 months), sinusitis (n = 5, 56 months), and dysphagia (n = 1). Overall, 41% of study results were positive: stridor (58%), laryngomalacia (61%), laryngitis (56%) and sinusitis (40%). Patients with otitis, dysphonia and laryngeal papillomatosis had GER in 1%, 14%, and 25%, respectively. Follow-up in the three larger groups of patients showed resolution of the ENT symptoms after medical treatment of the reflux in 83% of patients with stridor and reflux, 86% with laryngitis and reflux, and 80% with laryngomalacia and reflux. Four fundoplications were performed: one neurologically impaired patient, and four nonresponders.

CONCLUSIONS

The authors recommend that a pH study be performed in children with stridor, laryngomalacia, laryngitis, and sinusitis when faced with failure of the usual treatment. However, a pH study does not seem as beneficial for recurrent otitis, dysphonia, or laryngeal papillomatosis.
