In patients with corrected EA, half of the reflux events could be detected only by MII. We also demonstrated that weakly acidic reflux can be responsible for the patients' symptoms. However, patients may have few or no symptoms despite poor esophageal function and extensive gastroesophageal reflux disease.

: Low fecal HBD-2 may be a risk factor in preterm infants to develop neonatal enteric disease, such as necrotizing enterocolitis.

Most measurements showed substantial to perfect intra- and interobserver agreement. Still, we found a few outliers presumably caused by poorer signal quality in some tracings rather than being observer dependent. An improvement of analysis results may be achieved by using a standard analysis protocol, a standardized method for judging tracing quality, better training options for method users, and more interaction between investigators from different institutions.

Accidental caustic ingestion is a common problem in young children at the age of 1 to 4 years. In cases of circular injuries of the oesophagus subsequent strictures can arise. Endoscopic balloon dilatation is the commonly used intervention but does not always lead to permanent improvement. We report the successful use of mitomycin C in a young boy in whom we could achieve ongoing relief of dysphagia after the unsuccessful long-term use of frequent endoscopic dilatations.
