Impact of early discharge from the maternity ward on the risk of neonatal rehospitalization: A case-control study.

Background: The time for newborn discharge from the maternity ward has been shortened in recent decades with consequences that are still debated.

Objectives: The primary objective of this study was to establish whether early discharge could be a risk factor for rehospitalization in the neonatal period. Second, we aimed to study the incidence of neonatal hospitalizations and their causes.

Infantile pyknocytosis, a neonatal hemolytic anemia with Heinz bodies: A cohort study.

Infantile pyknocytosis (IP) is a rare, probably misestimated, cause of non-immune neonatal hemolytic anemia evolving in two phases: an initial phase with severe jaundice, followed by a second phase with hemolytic anemia, which may require neonatal intensive care. The diagnosis of IP is based on the transient presence on blood smear of hyperdense, contracted, and/or spiculated red blood cells (pyknocytes), associated with the spontaneous resolution of clinico-biological features and the exclusion of other causes. If the etiology remains undetermined, some contributing factors, such as oxidative stress, have been proposed.
