ABSTRACT. Objective. To assess incidence and clinical risk factors of chronic oxygen dependency (COD) among survivors who were born at or before 31 weeks' gestation.Methods. This prospective, multicenter study enrolled 802 infants who were born at or before 31 weeks' gestation and admitted to 8 level III neonatal intensive care units in northern and eastern France from January 1 through December 31, 1997. Need for oxygen to maintain oxygen saturation between 92% and 96% was assessed at 28 days of life and at 36 and 42 weeks' postconceptional age (PCA). Stepwise logistic regression analysis was used to identify the incidence of COD and the risk factors related to its occurrence.Results. The mortality rate was 14%. Antenatal corticotherapy was administered to 51% of patients, surfactant therapy to 76% of the ventilated patients, and highfrequency oscillatory ventilation at day 1 to 32%. At 28 days and 36 and 42 weeks' PCA, respectively, 25%, 15%, and 6% of survivors had COD. After adjustment for intercenter variations, we identified the significant risk factors for COD at these dates: a low gestational age, a high score on the Clinical Risk Index for Infants, intrauterine growth restriction, and surfactant treatment.Conclusion. COD incidence was high at 28 days of life but decreased dramatically by 42 weeks' PCA. This study confirmed previously reported risk factors and underlined the importance of intrauterine growth restriction and the Clinical Risk Index for Infants as significant risk factors.

Abdominal pain in children and adolescents is difficult to evaluate, and the diagnosis of ovarian torsion remains a challenge. Because of its potential complications, we need effective clinical tools. From our review of the literature, it was not possible to develop a diagnostic algorithm. Further research is needed to improve our practice and shorten the delay to diagnosis. Considering the low incidence of ovarian torsion, a multicenter prospective study would be required.
Background and objectiveUrinary tract infection (UTI) represents the most common bacterial infection in infants, and its prevalence increases with the presence of high-grade vesicoureteral reflux (VUR). However, voiding cystourethrography (VCUG) is invasive, and its indication in infants <3 months is not yet defined. This study aims to investigate, in infants aged 0–3 months, if the presence of Escherichia coli versus non-E. coli bacteria and/or normal or abnormal renal ultrasound (US) could avoid the use of VCUG.MethodOne hundred and twenty-two infants with a first febrile UTI were enrolled. High-grade VUR was defined by the presence of VUR grade ≥III. The presence of high-grade VUR was recorded using VCUG, and correlated with the presence of E. coli/non-E. coli UTI and with the presence of normal/abnormal renal US. The Bayes theorem was used to calculate pretest and post-test probability.ResultsThe probability of high-grade VUR was 3% in the presence of urinary E. coli infection. Adding a normal renal US finding decreased this probability to 1%. However, in the presence of non-E. coli bacteria, the probability of high-grade VUR was 26%, and adding an abnormal US finding increased further this probability to 55%.ConclusionsIn infants aged 0–3 months with a first febrile UTI, the presence of E. coli and normal renal US findings allow to safely avoid VCUG. Performing VCUG only in infants with UTI secondary to non-E. coli bacteria and/or abnormal US would save many unnecessary invasive procedures, limit radiation exposure, with a very low risk (<1%) of missing a high-grade VUR.
ObjectivesTo investigate whether nebulised hypertonic saline (HS) treatment would decrease length of hospital stay (LOS) among infants with moderate-to severe-bronchiolitis compared with standard supportive care (SC).MethodsWe conducted an open, multicentre, randomised clinical trial from 1 April 2013 to 31 March 2016, in Swiss children’s hospitals. Patients aged 6 weeks to 24 months with a primary diagnosis of moderate or severe bronchiolitis were included. Children with previous episodes of wheezing, cardiac disease, chronic respiratory disease, immunodeficiency, prematurity (gestational age <34 weeks), corticotherapy in the preceding 2 weeks or inhaled bronchodilators within 24 hours before presentation were excluded. Patients were randomised to receive standard SC with nebulisation of 4 mL of 3% sodium chloride every 6 hours versus SSC. Main outcomes and measures were LOS duration of oxygen therapy, transfer to intensive care unit (ICU), readmission within 7 days following discharge and adverse events.Results121 children were randomised. No statistically significant differences were found between treatment groups at baseline (age, Wang Score, atopic history, smoking exposure). Children in the HS group had a non-significant difference in length of stay −2.8 hours (−10; 16) compared with the SC group. There were no differences in oxygen therapy duration, transfer to ICU, readmission rate or adverse events. The intervention was discontinued at the parents’ request in 16% of the cases.ConclusionOur study does not support the use of HS nebulisation in children with moderate to severe bronchiolitis.Trial registration numberNCT01812525.
Objective: To delineate the perinatal risk factors of neurodevelopmental disabilities in very preterm birth applying logistic regression analysis. Design: This prospective, geographically defined collaborative study was carried out in the Franche-Comté region of France. Subjects: From October 1, 1990 to September 30, 1992, perinatal and follow-up data were collected on 203 consecutive live-born singleton or twin non-malformed infants with strictly ascertained gestational ages of less than 33 weeks. Main Outcome Measure: The rate of cerebral palsy and/or severe mental retardation as diagnosed by a family physician or pediatrician with a screening-skill test performed at 2 years of age. Results: 167/171 (98%) survivors were evaluated. Twenty-two of the 167 examined infants (13%) showed signs of cerebral palsy, and 10 of these had severe cerebral palsy or mental retardation. Risk factors for disabilities were selected by a multivariate approach: premature rupture of membranes ≥48 h (OR 4.3, 95% CI 1.6–11.8); monochorionic twin placentation (OR 6.0, 95% CI 1.7–21.3), and respiratory distress syndrome (OR 2.8, 95% CI 1.1–7.1). Conclusion: This geographically defined prospective study gives epidemiological data and highly suggests that there is a link between prenatal events (premature rupture of membranes, monochorionic twin placentation), postnatal events (respiratory distress syndrome), and neurological disabilities in former preterm infants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
