Pronounced neonatal breast enlargement beyond the first week of life and its regression correlates with serum prolactin levels - a case series.

Objectives: Mild breast swelling is frequently observed in newborns during the first postnatal week. Breast enlargement is also observed in a minor proportion of infants beyond the first postnatal week, leading to discussions how to deal with it. Our objective was to review a case series of infants with prolonged breast swelling.

Differences in neonatal gastric tubes during insertion into a 3D model in relation to risk of potential perforation.

Objectives: Perforation of esophagus or stomach is a potential complication during and after insertion of a gastric tube in neonates. The aim of this study was to analyze different types of gastric tubes in a three-dimensional (3D) model of neonatal esophagus and stomach regarding potential perforations.

Methods: A 3D model of esophagus and stomach was created based on computed tomography data of a term neonate.
