We report three cases of transient myocardial hypertrophy, diagnosed by echocardiography, occurring between the second and seventh days of life in neonates with initially normal ventricular myocardial wall thickness. The three term neonates had perinatal injury with acute fetal distress. In all three cases electrocardiographic and biologic signs of(More)
Primary endobronchial tumors are rare in children and they include a broad spectrum of lesions. The aim of this study was to determine the characteristic features, treatments and outcomes of these tumors. We report a retrospective analysis of all patients treated for endobronchial tumor in nine French hospitals between 1990 and 2010 and a comparison of the(More)
Intraoperative Doppler sonographic examinations were carried out on seven preterm neonates to measure cerebral blood flow velocity changes in the anterior cerebral arteries during ductus arteriosus ligation. Age at surgery was 12±6 days. Continuous recordings during the operative procedure showed a rapid increase in diastolic blood pressure (P<0.01),(More)
AIMS The natural history of congenital or childhood non-immune, isolated atrioventricular (AV) block is poorly defined. METHODS AND RESULTS We retrospectively studied 141 children with isolated, non-immune AV block diagnosed in utero, or up to 15 years of age, at 13 French medical centres, between 1980 and 2009. Patients with structural heart disease or(More)
BACKGROUND The origin of congenital or childhood nonimmune isolated atrioventricular (AV) block remains unknown. We hypothesized that this conduction abnormality in the young may be a heritable disease. METHODS AND RESULTS A multicenter retrospective study (13 French referral centers, from 1980-2009) included 141 children with AV block diagnosed in utero,(More)
The effect of therapeutic doses of indomethacin versus placebo (saline) on cerebral hemodynamics was studied in nine mechanically ventilated preterm infants. Recordings were made at rest and during endotracheal suctioning. Indomethacin at a dose of 0.2 mg/kg body weight was infused over 5 min. Compared to placebo, there was a significant decrease in Doppler(More)
The authors describe the measurement of cardiac output by Doppler echocardiography in neonates and infants. After reviewing theoretical considerations, the authors review the various practical aspects of the method. They emphasize the need for an excellent technique so that possible errors are avoided. In their experience, the most appropriate measurement(More)
INTRODUCTION Systemic corticosteroid therapy is the usual treatment for hemangioma with vascular risk. Tolerance to such treatment is usually good. OBSERVATION A two Month-old girl presented with a hemangioma of the lower right eyelid that had developed since she was 15 days old. Treatment with betamethasone at the dose of 0.3 mg/kg/day was prescribed(More)
BACKGROUND Percutaneous closure of large persistent ductus arteriosus using the Amplatzer duct occluder is an alternative to surgery. However, this device is not recommended in infants weighing less than 6 kg. AIM To evaluate the safety and effectiveness of this procedure in low-body-weight infants. METHODS We reviewed retrospectively data for infants(More)
