Current situation of pediatric cystic fibrosis-related liver disease: results of a Spanish nationwide study.

Background: Cystic fibrosis-related liver disease (CFRLD) is a health problem that can affect as many as 30-40% of cystic fibrosis patients by the age of 12 years. We studied the epidemiology of CFRLD thanks to the first exclusively pediatric CFRLD patient registry to date.

Methods: Descriptive cross-sectional study.

Heterotopic gastric mucosa of the proximal oesophagus (inlet patch): endoscopic prevalence, histological and clinical characteristics in paediatric patients.

Background: Heterotopic gastric mucosa is found in the proximal oesophagus, just below the upper oesophageal sphincter, and is encountered when the oesophagus is examined carefully during endoscopy.

Aims: In this study on paediatric patients, we aimed to determine the endoscopic prevalence of heterotopic gastric mucosa of the proximal oesophagus (HGMPO), to identify its macroscopic and histological characteristics and to evaluate its clinical features.

Patients And Methods: A total of 1399 patients were examined.
