Nutrition of Preterm Infants and Raw Breast Milk-Acquired Cytomegalovirus Infection: French National Audit of Clinical Practices and Diagnostic Approach.

Raw breast milk is the optimal nutrition for infants, but it is also the primary cause of acquired cytomegalovirus (CMV) infection. Thus, many countries have chosen to contraindicate to feed raw breast milk preterm infants from CMV-positive mothers before a corrected age of 32 weeks or under a weight of 1500 g. French national recommendations have not been updated since 2005. An audit of the French practices regarding the nutrition with raw breast milk in preterm infants was carried out using a questionnaire sent to all neonatal care units. Diagnosed postnatal milk-acquired CMV infections have been analysed using hospitalisation reports. Seventy-five percent of the neonatal units responded: 24% complied with the French recommendations, 20% contraindicated raw breast milk to all infants before 32 weeks regardless of the mothers' CMV-status, whereas 25% fed all preterm infants unconditionally with raw breast milk. Thirty-five cases of infants with milk-acquired CMV infections have been reported. The diagnosis was undeniable for five patients. In France, a high heterogeneity marks medical practices concerning the use of raw breast milk and the diagnostic approach for breast milk-acquired CMV infection is often incomplete. In this context, updated national recommendations and monitored CMV infections are urgently needed.

Study of the Factors Leading to Fetal and Neonatal Dysthyroidism in Children of Patients With Graves Disease.

CONTEXT: Neonatal hyperthyroidism was first described in 1912 and in 1964 was shown to be linked to transplacental passage of maternal antibodies. Few multicenter studies have described the perinatal factors leading to fetal and neonatal dysthyroidism. OBJECTIVE: To show how fetal dysthyroidism (FD) and neonatal dysthyroidism (ND) can be predicted from perinatal variables, in particular, the levels of anti-thyrotropin receptor antibodies (TRAbs) circulating in the mother and child. DESIGN AND PATIENTS: This was a retrospective multicenter study of data from the medical records of all patients monitored for pregnancy from 2007 to 2014. SETTING: Among 280,000 births, the medical records of 2288 women with thyroid dysfunction were selected and screened, and 417 women with Graves disease and positive for TRAbs during pregnancy were included. RESULTS: Using the maternal TRAb levels, the cutoff value of 2.5 IU/L best predicted for FD, with a sensitivity of 100% and specificity of 64%. Using the newborn TRAb levels, the cutoff value of 6.8 IU/L best predicted for ND, with a sensitivity of 100% and a specificity of 94%. In our study, 65% of women with a history of Graves disease did not receive antithyroid drugs during pregnancy but still had infants at risk of ND. CONCLUSIONS: In pregnant women with TRAb levels ≥2.5 IU/L, fetal ultrasound monitoring is essential until delivery. All newborns with TRAb levels ≥6.8 IU/L should be examined by a pediatrician with special attention for thyroid dysfunction and treated, if necessary.

Livedo Reticularis: A Presenting Sign of Escherichia Coli Sepsis in a Newborn.

UNLABELLED: Livedo reticularis is a red cutaneous netlike pattern that is caused by abnormalities of the microvascularization and can be associated with many other potential systemic etiologies. We describe a case of a newborn that presented with livedo reticularis on his first day of life without any obvious systemic signs. The livedo reticularis was associated with Escherichia Coli K1 meningitis as revealed by laboratory tests. Clinical infectious signs developed a few hours later. Despite appropriate antibiotics therapy, he died on his second day because of sepsis and disseminated intravascular coagulation. Cerebrospinal fluid culture, blood culture, and culture of samples from trachea showed the presence of Escherichia Coli serotype K1 with many virulence determinants. CONCLUSION: In newborn, livedo reticularis must not be considered as physiological, but as a potential sign of unknown severe bacterial infection. Thus, the presence of livedo reticularis must require urgent laboratory tests.

Breastfeeding duration and cognitive development at 2 and 3 years of age in the EDEN mother-child cohort.

OBJECTIVE: To investigate the dose-response relationship between breastfeeding duration and cognitive development in French preschool children. STUDY DESIGN: In the French EDEN Mother-Child Cohort Study, we evaluated language ability with the Communicative Development Inventory (CDI) in 1387 2-year-old children and overall development with the Ages and Stages Questionnaire (ASQ) in 1199 3-year-old children. Assessments were compared between breastfed and non-breastfed children and also according to breastfeeding duration in multivariable linear models, controlling for a wide range of potential confounders. We tested departure from linearity. RESULTS: After adjustments, ever-breastfed children scored 3.7 ± 1.8 (P = .038) points higher than never-breastfed children on the CDI and 6.2 ± 1.9 (P = .001) points higher on the ASQ. Among breastfed children, exclusive and any-breastfeeding durations were positively associated with both CDI and ASQ scores. The fine motor domain of ASQ was associated with any-breastfeeding duration, and the problem solving domain with exclusive-breastfeeding duration. We did not observe significant departures from linearity. No interactions were found between the child's sex, parental education or socioeconomic status, and breastfeeding duration. CONCLUSION: Longer breastfeeding duration was associated with better cognitive and motor development in 2- and 3-year-old children and a dose-response relationship was suggested.

Risk factors for developing transient neonatal cholestasis.

OBJECTIVES: To describe the incidence and the characteristics of neonatal cholestasis in a cohort of patients with known risk factors and to investigate additional risk factors. METHODS: A prospective observational study conducted between April 2008 and 2009 involved all neonates admitted in the neonatal ward. They were divided into high- and low-risk groups for cholestasis. The high-risk group included preterm birth <34  weeks of gestation, small for gestational age (SGA), parenteral nutrition (PN) >7 days, abdomino-pelvic or thoracic surgery. Bilirubinemia was weekly measured in the high-risk group. RESULTS: Of the 460 newborns studied, 234 were included in the high-risk group and 226 in the low-risk group. Cholestasis developed in 32 patients (13.7%) in the high-risk group at mean (SD) age of 14.7 (12.9) days; all were receiving PN. None of the patients in the low-risk group developed cholestasis. An analysis was carried out in the 207 patients in the high-risk group who received PN. The odds ratio (OR) for developing cholestasis was 2.3 [1.1-5.0] and 5.6 [2.5-12.5] for SGA or surgical patients, respectively. Cholestasis was associated with neonatal severe conditions, longer PN duration, and more intravenous macronutrients' intakes. In multivariate analysis, SGA and neonatal surgery were strong independent risk factors for cholestasis, with OR (95% confidence interval [95% CI]) of 4.4 [1.6-12.5] and 4.6 [1.7-12.3], respectively. CONCLUSIONS: Transient neonatal cholestasis is a complication of PN. SGA and neonatal surgery are additional risk factors. There is no evidence to limit intravenous protein intakes in preterm.
