[Prevention of prematurity's complications]. / Prévention des complications de la prématurité.

Prematurity remains a leading cause of mortality and morbidity in neonates and children. Prevention of preterm birth and of its complications is a major public health issue. From before conception to long term follow up, many health actors are engaged in this preventive strategy with the same goal : to give the best quality of life for these vulnerable young patients. We will review different preventive aspects during antenatal and perinatal period, during NICU (Neonatal Intensive Care Unit) stay and after discharge. Prevention of prematurity's complications requires a global approach including respiratory, nutritional and infectious aspects among others. Neuroprotective strategies are a key point of this global approach.

La prématurité reste une cause majeure de mortalité et morbidité néonatales et infantiles. La prévention des naissances prématurées et de leurs complications est donc un enjeu majeur de santé publique. De la période pré-conceptionnelle au suivi à long terme de ces enfants, nombreux sont les acteurs impliqués dans un même objectif : offrir la meilleure qualité de vie à ces jeunes patients vulnérables. Nous reverrons ici différents aspects préventifs en période anténatale, périnatale, lors du séjour en néonatologie et lors du suivi après la sortie. La prévention des complications de la prématurité nécessite une prise en charge globale intégrée incluant, notamment, des aspects ventilatoires, nutritionnels, infectieux, néphrologiques et métaboliques. La neuroprotection est au centre des préoccupations et guide l'ensemble de l'approche.

Cardiac papillary fibroelastoma of a bicuspid aortic valve in an adolescent: A case report.

Cardiac papillary fibroelastomas (CPFE) are exceptional primary benign cardiac tumours affecting the heart valves. We report here the case of a 15-year-old boy in whom echocardiography performed for non-specific chest pain during follow-up for bicuspid aortic valve showed as accidental finding the presence of a round mobile mass without stalk attached on the inferior side of the aortic valve. The mass did not cause any outflow tract obstruction or aortic insufficiency. Electrocardiogram-gated cardiac computed tomography and magnetic resonance imaging allowed to suspect CPFE. Although the patient was asymptomatic, open cardiac surgery with elective surgical resection of the tumour was performed to avoid systematic emboli. Histology confirmed the diagnosis of CPFE. This is an exceptional case of acquired CPFE in a young patient with bicuspid aortic valve. Due to the risk of systemic embolization, aortic or coronary ostium obstruction, elective excision of such lesions is recommended.
