[Glucocorticoid-induced hypertrophic cardiomyopathy in premature infants: apropos of 4 cases].

Background: The steroidal treatment used to prevent bronchopulmonary dysplasia (BD) in the preterm babies may be the cause of several complications, one of them being hypertrophic cardiomyopathy.

Case Report: Four infants developed hypertrophic cardiomyopathy during glucocorticoid (dexamethasone and/or betamethasone) treatment for bronchopulmonary dysplasia. In one of them, septal hypertrophy led to left ventricular outflow tract obstruction and congestive heart failure.

[Post-traumatic pulmonary pseudocysts].

Background: Pulmonary pseudocyst is an unusual complication of chest trauma.

Case Report: A 12-year-old boy suffered from a non penetrating chest trauma. Examination was normal except mild hemoptysis.

[Cerebral arteriovenous malformations in a probable familial form of Rendu-Osler disease].

Cerebral arteriovenous malformations with neonatal manifestations are infrequent and virtually always fatal. Heart failure with an intracranial bruit is the most common presentation. Exceptionally, the aneurysm is a manifestation of Rendu-Osler-Weber syndrome which is inherited on an autosomal dominant basis.
