BACKGROUND AND OBJECTIVE: Congenital pulmonary malformations (CPM) are mostly recognized on prenatal ultrasound scans. In a minority of cases, they may impair breathing at birth. The factors predictive of neonatal respiratory distress are not well defined, but an understanding of these factors is essential for decisions concerning the need for the delivery to take place in a tertiary care center. The aim of this study was to identify potential predictors of respiratory distress in neonates with CPM. METHODS: We selected cases of prenatal diagnosis of hyperechoic and/or cystic lung lesions from RespiRare, the French prospective multicenter registry for liveborn children with rare respiratory diseases (2008–2013). Prenatal parameters were correlated with neonatal respiratory outcome. RESULTS: Data were analyzed for 89 children, 22 (25%) of whom had abnormal breathing at birth. Severe respiratory distress, requiring oxygen supplementation or ventilatory support, was observed in 12 neonates (13%). Respiratory distress at birth was significantly associated with the following prenatal parameters: mediastinal shift (P = .0003), polyhydramnios (P = .05), ascites (P = .0005), maximum prenatal malformation area (P = .001), and maximum congenital pulmonary malformation volume ratio (CVR) (P = .001). Severe respiratory distress, requiring oxygen at birth, was best predicted by polyhydramnios, ascites, or a CVR >0.84. CONCLUSIONS: CVR >0.84, polyhydramnios, and ascites increased the risk of respiratory complications at birth in fetuses with CPM, and especially of severe respiratory distress, requiring oxygen supplementation or more intensive intervention. In such situations, the delivery should take place in a tertiary care center.
Objectives To review perinatal and neurodevelopmental outcome (NDO) following selective fetoscopic laser coagulation (SFLC), cord coagulation (CC) or expectant management of monochorionic diamniotic twin pregnancies complicated with selective intrauterine growth restriction (sIUGR) and absent or reverse end-diastolic flow (AREDF) in the umbilical arteries (UA). Design and setting Single-centre retrospective observational study. Population 108 cases of sIUGR diagnosed before 26 +6 weeks' gestation with AREDF in the UA. Methods Survival rate and potential risk factors were analysed. NDO was assessed using parental questionnaires. Main outcomes measures Survival, gestational age at delivery and NDO.
ObjectiveAlveolar capillary dysplasia (ACD) is one of the causes of pulmonary hypertension. Its diagnosis is histological but new pathogenetic data have emerged. The aim of this study was to describe a French cohort of patients with ACD to improve the comprehension and the diagnosis of this pathology which is probably underdiagnosed.MethodsA retrospective observational study was conducted in French hospitals. Patients born between 2005 and 2017, whose biological samples were sent to the French genetic reference centres, were included. Clinical, histological and genetic data were retrospectively collected.ResultsWe presented a series of 21 patients. The mean of postmenstrual age at birth was 37.6 weeks. The first symptoms appeared on the median of 2.5 hours. Pulmonary hypertension was diagnosed in 20 patients out of 21. Two cases had prolonged survival (3.3 and 14 months). Histological analysis was done on lung tissue from autopsy (57.1% of cases) or from percutaneous biopsy (28.6%). FOXF1 was found abnormal in 15 patients (71.4%): 8 deletions and 7 point mutations. Two deletions were found by chromosomal microarray.ConclusionThis study is one of the largest clinically described series in literature. It seems crucial to integrate genetics early into diagnostic support. We propose a diagnostic algorithm for helping medical teams to improve diagnosis of this pathology.
Background: Abnormal interhemispheric synchrony has been described in many clinical compromises in brain function, but its prognostic value in neonatal hypoxic-ischemic encephalopathy (HIE) is unknown. Objectives: The study aimed at describing the frequency of abnormal interhemispheric synchrony in infants with HIE and to explore its prognostic value. The main outcome was survival without major disabilities. Methods: We performed a single-center retrospective cohort study and enrolled 40 neonates with HIE who underwent hypothermia. Results: Abnormal interhemispheric synchrony was observed in 23% of the patients with HIE. Sensitivity and specificity values for predicting survival without major disabilities were 90 and 67% for seizures, 50 and 97% for status epilepticus, 60 and 97% for highly abnormal EEG in the first 48 h, and 80 and 97% for EEG asynchrony, respectively. The prognostic value of asynchrony improved to 100% sensitivity, whereas specificity remained unchanged, when associated with highly abnormal EEG within the first 48 h of life. Conclusions: Abnormal interhemispheric synchrony was observed in a quarter of the patients with HIE. This pilot study suggests that the prognostic value of asynchrony is excellent, especially when combined with EEG background analysis.
