Gastroesophageal reflux (GER) may have a role in upper airway disease such as chronic sinusitis and pharyngolaryngitis. Methods of assessment of reflux, although never absolute, are useful in selecting GER as a component in the induction of upper respiratory disease. Patients with intractable sinusitis and otitis have been found to respond to anti-reflux therapy as noted in the cases of this article.

Gastroesophageal reflux (GER) into the laryngopharynx causes or contributes significantly to a variety of upper respiratory problems in children. The pH probe, laryngeal examinations, and broncholveolar lavage results for children with subglottic stenosis, recurrent croup, apnea, chronic cough, laryngomalacia, recurrent choanal stenosis, vocal fold nodules, and chronic sinusitis/otitis/bronchitis were reviewed in an effort to quantify the role of GER in each of these disorders. This review suggests that GER plays a causative role in subglottic stenosis, recurrent croup, apnea, and chronic cough. It is an important inflammatory cofactor in laryngomalacia and possibly in true vocal cord nodules and problematic recurrent choanal stenosis. GER is also an important inflammatory cofactor in chronic sinusitis/otitis/bronchitis but may be the result of chronic illness in the older patients.

The purpose of this study is to examine the relation between gastroesophageal reflux and allergy as possible causes of chronic tubotympanal pathology. The 30 examined children (ages 2-13) were divided into two groups based on the otological criteria. The 16 examined children suffered from a secretory otitis, which lasted more than four months. Upon further examination with a microscope, seven of these children exhibited symptoms of the adhesive process of the middle ear. Furthermore, 14 patients suffered from a recurrent otitis, i.e. more than five cases of otitis per year, while five patients from this group suffered from a chronic otitis with a central defect of the tympanum. The method used for the examination of the gastroesophageal reflux consisted of a continual 24 h esophageal pH monitoring. The particular apparatus used for this included antimony electrode (Synetics Medical, Sweden), while the analysis we performed was processed through the PC software program Gastrosoft Inc. The reflux index higher than five was considered pathological. At the time of the gastroesophageal reflux examination, we also performed the allergological analysis. The presence of allergy was confirmed by three methods: the positive allergological anamnesis, the positive skin pick test and by the elevated quantities of specific IgEs (Pharmacia CAP system). The examination resulted in the following: 18 of the examined children suffered from the pathological gastroesophageal reflux (60%); further seven of our patients tested positive on the allergological test (23%); and the four who tested positive for allergy also suffered from the pathological gastroesophageal reflux (13%). In comparison with allergies, the pathological GER was substantially more frequent in the patients who suffered from chronic tubotympanal disorders.

Gastroesophageal reflux disease has frequently been implicated in a wide variety of complications beyond the esophagus. These so-called "extraesophageal" disorders range from diseases of the respiratory tract, such as asthma and bronchitis, to more remote sites and conditions such as otitis and dental erosion. Many articles proposing a link between reflux disease and a multitude of extraesophageal complications have been published, but indisputable evidence that these conditions are caused by reflux disease is rare. Much of the support for a link between reflux disease and a number of extraesophageal complications is based on the observation that reflux disease frequently coexists with other disorders. A causal link is difficult to prove, however, and this review aims to critically evaluate the available evidence, looking, where possible, at longitudinal studies, expert diagnoses, and response to acid-suppressive therapy as a means of determining the true relationship between GERD and its putative extraesophageal complications.

Vomiting after feeding is a symptom of gastroesophageal reflux (GER) and of eosinophilic esophagitis (EE), which are considered to be a cause of infant feeding disorder. The objective of the present study was to evaluate swallowing in children with feeding disorder manifested by vomiting after feeding. Using clinical and videofluoroscopic methods we studied the swallowing of 37 children with vomiting after feeding (mean age=15.4 months), and of 15 healthy children (mean age=20.5 months). In the videofluoroscopic examination the children swallowed a free volume of milk and 5 ml of mashed banana, both mixed with barium sulfate. We evaluated five swallows of liquid and five swallows of paste. The videofluoroscopic examination was recorded at 60 frames/s. Patients had difficulty during feeding, pneumonia, respiratory distress, otitis, and irritability more frequently than controls. During feeding, children with vomiting, choke were irritable, and refused food more frequently than controls, and during the videofluoroscopic examination the patients had more backward movement of the head than controls for both the liquid and paste boluses. There was no difference in the timing of oral swallowing transit, pharyngeal swallowing transit, or pharyngeal clearance between patients and controls. We conclude that children with vomiting after feeding may have difficulties in accepting feeding, although they have no alteration of oral and pharyngeal phases of swallowing.

Helicobacter pylori (H. pylori) is one of the frequently encountered micro-organisms in the aerodigestive tract. Although infections caused by H. pylori are this common, the exact mode of transmission has not been fully understood yet. Oral-oral, fecal-oral and gastrointestinal-oral routes are the possible modes of transmission. This infection is usually acquired in childhood and may persist for the whole life of the patient. However, about 80% of the infected humans are asymptomatic. Human stomach was considered to be the only reservoir of H. pylori until bacteria were discovered in human dental plaque, in oral lesions, in saliva, in tonsil and adenoid tissue. It is suggested that H. pylori enters the nasopharyngeal cavity by gastroesophageal reflux and colonize in the dental plaques, adenoid tissues and tonsils. From these localizations, the bacteria ascend to the middle ear and to the paranasal sinuses directly or by the reflux again and may trigger some diseases, including otitis, sinusitis, phyrangitis, laryngitis and glossitis. But still, the exact mechanism remains unclear.

Gastroesophageal reflux is considered a risk factor for recurrent or persistent upper and lower respiratory tract conditions including asthma, chronic cough, sinusitis, laryngitis, serous otitis and paroxysmal laryngospasm. Fifty-one subjects with recurrent (more than three) episodes of upper respiratory tract infection (URTI), serous otitis or sinusitis who had been admitted to an earnose- throat (ENT) outpatient clinic during the previous year were enrolled in the present study to evaluate the presence of laryngeal and/or esophageal reflux. The participants, who were randomly selected, were questioned about symptoms of reflux, including vomiting, abdominal pain, failure to thrive, halitosis, bitter taste in the mouth, chronic cough, heartburn, constipation and hoarseness. All subjects had an endoscopic examination, an otoscopic examination, a tympanogram and upper GI system endoscopy. Esophagitis was diagnosed endoscopically and histologically. The likelihood of occurrence of esophagitis was found to be higher only among subjects with postglottic edema/erythema as determined by pathological laryngeal examination. The reflux complaints reported did not predict the development of esophagitis, but the odds of esophagitis occurring were ninefold greater among subjects with recurrent otitis. Of the subjects, 45.1% were Helicobacter pylori-positive. However, no association was found between esophagitis and Helicobacter pylori positivity. The likelihood of the occurrence of esophagitis was found to be increased in the presence of recurrent otitis media and/or postglottic edema, irrespective of the presence of reflux symptoms. We concluded that, in contrast to the situation where adults are concerned, the boundaries for discriminating laryngopharyngeal reflux from gastroesophageal reflux are somewhat blurred in pediatric patients.
