DIAGNOSTIC EVALUATION AND CLINICAL FINDINGS IN CHILDREN WITH PERSISTENT TACHYPNEA OF INFANCY/NEUROENDOCRINE CELL HYPERPLASIA OF INFANCY: A EUROPEAN MULTICENTER RETROSPECTIVE STUDY.

Background: Persistent tachypnea of infancy (PTI)/neuroendocrine cell hyperplasia of infancy (NEHI) is a form of childhood interstitial lung disease (chILD) that predominantly affects young children. Although it is one of the most common chILDs, there is no unified diagnostic approach specific to this condition.

Research Question: Is there a difference in the clinical presentation and the diagnostic approach in PTI/NEHI patients between the European countries?

Study Design And Methods: This was a European multicenter, retrospective, observational study.
