Two cases of fractures in neonates associated with maternofetal vitamin D deficiency.

Vitamin D supplementation is essential for the entire population, especially during pregnancy and in the pediatric period. We report two case studies of full-term newborns who presented long-bone fractures associated with severe vitamin D deficiency transmitted to them by their mothers, even though maternal supplementation had been implemented according to the existing recommendations. These observations encourage the investigation of neonatal vitamin D deficiency in the presence of long-bone fractures in the absence of traumatic birth and the necessity of reenforcing the means of prevention and the selection of risk groups in order to adjust vitamin D supplementation during pregnancy individually.

[Neonatal meningitis due to Listeria monocytogenes after 3 weeks of maternal treatment during pregnancy]. / Méningite néonatale àListeria monocytogenes après traitement maternel de 3 semaines pendant la grossesse.

We report the case of a pregnant woman with listeriosis at 26 gestational weeks followed by premature labor at 30 gestational weeks. Bacterial meningitis was suspected in the neonate with ventriculitis on sonography, a high level of protein in the cerebrospinal fluid (CSF), and an identified specific bacterial genome of Listeria monocytogenes (PCR 16S rDNA and sequencing and specific amplification of L. monocytogenes hly gene) in CSF. Neonatal meningitis was complicated with cerebral venous sinus thrombosis and ventriculomegaly. Listeriosis during pregnancy can lead to severe complications in the neonate. Thus, listeriosis should be a diagnostic concern in febrile pregnant women at any stage of pregnancy. First-line treatment is based on high-dose amoxicillin (> or =6g/day) and must be used for at least 3 weeks for treatment of listeriosis during pregnancy. If the fetus survives, longer therapy until delivery can be discussed.

[Validation trial of a neonatal prophylactic antibiotic protocol in the delivery room]. / Essai de validation d'un protocole d'antibioprophylaxie néonatale en salle de travail.

Maternofetal infection occurs in 1 to 10 of every 1,000 newborns. Prognosis is poor and an extremely rapid the clinical course is sometimes observed. The situation suggests that widespread use of antibiotics and more than 90% of the newborns receiving antibiotics are not infected. A prospective study based on simple, recognized criteria predictive of maternal-fetal infection was conducted in 3,392 deliveries to evaluate the effect of an antibiotic prophylaxy protocol. Specificity, sensitivity, positive and negative predictive value were evaluated for each of the eleven criteria retained with the goal of increasing sensitivity and decrease the use of unnecessary antibiotics. Among the 3,392 infants delivered from January 1989 to December 1990, 286 (8.4%) newborns entered the study and were given mezlocillin (150 mg/kg/12 h). This treatment was stopped at 48 hours of life if the infant was not infected. RESULTS. Infection was confirmed in 48 of 3,392 infants (1.4%). All were in the risk group: 48/286 (16.7%). The germs the most often found were group B Streptococcus (n = 16), Escherichia coli (n = 8) and Listeria monocytogenes (n = 3). Nine criteria were well correlated with maternal-fetal infection. The two most important criteria were maternal pyrexia above 39 degrees C and Apgar score below 7 to 5 min (poor neonatal adaptation), with a 99% and 90% and a positive predictive value of 80% and 37% respectively. Inversely, Two criteria were poorly correlated with maternal-fetal infection: labour duration above 12 hours and instrumental extraction (positive predictive value from 10% to 17%).(ABSTRACT TRUNCATED AT 250 WORDS)
