[Early-onset neonatal infection: assessment of professional practices in 14 maternity wards in the Île-de-France region in 2013]. / Infections néonatales bactériennes précoces : évaluation des pratiques professionnelles dans 14 maternités d'Île-de-France en 2013.

INTRODUCTION: Early-onset neonatal infection remains a major cause of morbidity and mortality in neonates. Both universal vaginal screening for group-B streptococcus (GBS) and intrapartum antibiotic prophylaxis have decreased the incidence of early-onset GBS disease. Almost 12 years after the implementation of the French recommendations, we assessed the practices around screening, diagnosis, and treatment of early-onset neonatal infection in the Île-de-France region. PATIENTS AND METHODS: We conducted a prospective, multicenter, observational study in 14 volunteer maternity wards from 18 to 31 March 2013. All live newborn infants delivered at 35 gestational weeks or more were eligible. Maternal, obstetrical, and neonatal characteristics were collected, as well as the management of suspected early-onset neonatal infections. RESULTS: A total of 1194 mothers and 1217 neonates were included. Among the latter, 54% had bacteriological samplings at birth, with at least a gastric aspirate. Bacteriological samples were collected at birth in 85% of cases based on major or minor anamnestic infection criteria defined by the French National Authority for Health in 2002. In addition, 26% of neonates had at least one blood sample taken. Antibiotic treatment was administered in 4% of the infants with cefotaxime administered in two thirds of cases. CONCLUSION: An update of the French guidelines for the management of early-onset neonatal infections is required in order to improve targeting of newborn infants suspected of having an infection and to optimize the antibiotics administered. Moreover, the role of bacteriological sampling at birth needs to be clarified.

[Necrotizing enterocolitis and apnoeas-bradycardias of the preterm newborn]. / Entérocolite ulcéro-nécrosante et apnées-bradycardies du nouveau-né prématuré

UNLABELLED: We conducted a case control study during six and a half years with the objective to analyse the risk factors for NEC. POPULATION AND METHODS: All cases of confirmed NEC matched to controls for identical gestational age and period of hospitalization; apnoeas-bradycardias prospectively counted. RESULTS: Forty-five cases were compared to 89 controls. The isolated risk factors were: an intra-uterine growth retardation (OR = 3,65, 95% confidence interval [CI] 95%: 1,54-8,63); a birth weight < 1000 g (OR = 8,16, CI 95%: 1,17-56,62), compared to a weight >/= 1500 g; a triple antibiotherapy (OR = 6,15, CI 95%: 1,16-32,45); an umbilical venous catheterization (OR = 2,64, CI 95%: 1,09-6,44); a number of simple apnoeas-bradycardias >/= 3rd tercile (n = 27) (OR = 4,54, CI 95%: 1,29-15,93), or severe (stimulated or with hypoxia) apnoeas-bradycardias >/= 3rd tercile (n = 8) (OR = 6,15, CI 95%: 1,59-23,75); an haemoglobin level lower than the 1(st) tercile (95 g/L) (OR = 5,90, CI 95%: 1,20-20,13); and milk thickening by Gumilk (OR = 2,78, CI 95%: 1,11-6,90). CONCLUSION: In the present practices, anoxo-ischemic factors during the first week of life do not represent an important risk of NEC; a great vigilance must be exercised for indications of the triple antibiotherapy and the treatment of apnoeas-bradycardias.

[Standardized oculocardiac reflex in ex-premature near full term (93 cases)]. / Réflexe oculocardiaque standardisé chez l'ex-prématuré à proximité du terme (93 cas).

UNLABELLED: The aim of the study was to present data investigating vagal reactivity in a population of premature infants reaching term, using the oculo-cardiac reflex. PATIENTS AND METHODS: Ninety three premature infants, free of any disease, near full term at the moment of testing, were prospectively investigated at a time close to discharge from neonatal unit. After an all-night polygraphic recording, a standardized oculo-cardiac reflex test was performed during quiet sleep. Data were classified in relation to both chronological and postconceptional ages. Simple liner regression analyses were performed on the selected variables. RESULTS: The results showed heterogeneity of the vagal response in this population: longest asystole (1049 ms +/- 540; 95th percentile = 1894 ms); maximal percentage of deviation between two successive RR intervals (88% +/- 90; 95th percentile = 200%); and duration between the beginning of decrease in heart rate and return to mean heart rate (14 s +/- 10; 95th percentile = 30 s). CONCLUSION: Our healthy premature infants at time of discharge exhibited a wider range of vagal reactivity than previously reported for the full term newborns. Considering our findings, we recommend caution before proceeding with treatment of vagal bradycardia in a similar premature infant population.

[Early revealing of Williams-Beuren syndrome by digestive disorders]. / Révélation précoce par des troubles digestifs d'un syndrome de Williams-Beuren.

UNLABELLED: Williams-Beuren syndrome is a rare syndrome for which diagnosis is usually made during early childhood. It includes mental retardation, friendly outgoing personality, typical facies, supravalvular aortic stenosis and hypercalcemia. CASE REPORT: We report the case of a newborn whose gastroesophageal reflux led to the diagnosis of Williams-Beuren syndrome. Hypercalcemia is known to precipitate digestive symptoms but was not present in this case. CONCLUSION: Announcing such a diagnosis in the neonatal period is difficult and may destabilize the family, but at least allows early care of the cardiovascular pathologies that may lead to death.
