Background: Resistant Kawasaki disease (KD) represents 10%-15% of KD patients and increases risk of coronary artery abnormalities (CAAs). Different scores exist to predict resistant KD but only in Japanese population, although a French team has recently proposed a new scoring system. The principal objective of this study is to establish criteria to predict resistant KD in our representative French population.

Article Synopsis
  • This study investigates the impact of noise on the relationship between fetal growth restriction (FGR) or small for gestational age (SGA) in single pregnancies and exposure to air pollution in two French cities between 2005 and 2009.
  • Researchers analyzed data from 8,994 pregnancies, identifying 587 cases of FGR and 918 cases of SGA, while measuring outdoor air pollution (nitrogen dioxide and particulate matter) and noise levels at mothers' residences.
  • Findings indicate a significant association between increased particulate matter exposure and fetal growth issues, specifically during the late stages of pregnancy, while noise exposure showed no connection to FGR or SGA.

Multiple risk factors are associated with adverse pregnancy outcomes (APO), but how all these different factors combine and accumulate remains unknown. The objective of this observational retrospective study was to describe the accumulation of multiple vulnerability markers in pregnant women living in an urban area. Women living in Besançon (France) who delivered between 2005 and 2009 were included.

Article Synopsis
  • This study focuses on the effects of air pollution, specifically nitrogen dioxide (NO), on fetal growth in women with multiple pregnancies, which are often excluded from such research.
  • Conducted in Besançon and Dijon between 2005 and 2009, it examined medical records and assessed NO exposure based on residential addresses during key pregnancy periods.
  • Results showed no link between NO and small for gestational age infants, but indicated a potential association between higher NO exposure and fetal growth restriction, highlighting the need for further investigation even at pollution levels below EU standards.

Article Synopsis
  • Current estimates of health outcomes for preterm infants are essential for improving perinatal care and guiding clinical practices and parental decisions.
  • The EPIPAGE-2 study analyzed the survival and health issues of infants born between 22 and 34 weeks of gestation in France in 2011, comparing results with a similar study from 1997.
  • Survival rates significantly improved with gestational age, with only 0.7% survival for infants under 24 weeks compared to 98.9% for those born at 32-34 weeks, while neonatal morbidity also decreased alongside gestational age.

Background And Purpose: Transfontanellar contrast enhanced ultrasound (TCEUS) in infants with neurological diseases has not been previously reported. Thus, the objective of our study was to describe the imaging findings of transfontanellar contrast enhanced ultrasound (TCEUS) performed in various neurological conditions in infants and to compare the findings with non-enhanced transfontanellar ultrasound (TFUS) and MRI.

Methods: Local institutional review board approval was obtained and, because of the need to catheterize children for contrast media administration, written informed consent of parents was obtained prior to all performed TCEUS.

Objective: To evaluate the relationship between preterm premature rupture of membranes (PPROM) and cognitive impairment in 5-year-old children born very preterm.

Study Design: The Etude Epidémiologique sur les Petits Ages Gestationnels Study is a population-based cohort of children followed up from birth to age 5 years recruited in 9 French regions in 1997. We analyzed data from singletons born between 24 and 32 weeks gestation categorized into 4 groups according to etiology of prematurity: infants born after PPROM, after idiopathic preterm labor, in a vascular context (Vasc), and to women with other complications (Other).

In infants the cardiorespiratory system undergoes significant functional maturation after birth and these changes are sleep-state dependent. Given the immaturity of these systems it is not surprising that infants are at risk of cardiorespiratory instability, especially during sleep. A failure of cardiovascular control mechanisms in particular is believed to play a role in the final event of Sudden Infant Death Syndrome (SIDS).

Objectives: Only few studies are available in the literature on sleep in children with Prader-Willi syndrome (PWS) and one single study analyzed the cyclic alternating pattern (CAP) in young adults with PWS, showing that patients with a higher proportion of A1 subtypes presented less severe GH deficiency. The aims of our study were to evaluate CAP in children with PWS compared to an age-matched control group and to evaluate the differences between PWS children with (GH+) and without (GH-) GH therapy.

Methods: Laboratory polysomnographic sleep recordings were obtained from 30 children with PWS (17 GH- and 13 GH+ patients) and 15 age-matched normal controls.
