ABSTRACT

Congenital cytomegalovirus (CMV) infection is the most common non-genetic cause of hearing loss and neurological disorder in children. Its overall prevalence is approximately 0.5% in Europe. In France, systematic screening during pregnancy is not recommended; screening is performed only if there are maternal or fetal symptoms suggestive of this infection. Approximately 90% of infected newborns are asymptomatic at birth, and among them the risk of neurosensory sequelae is 5-15%. By contrast, the prevalence of neurosensory impairment in symptomatic newborns at birth varies from 17% to 60%. Congenital CMV infection must be confirmed at birth before the 21st day of life by polymerase chain reaction (PCR) on saliva or urine samples. A complete clinical examination, blood tests (blood count, liver function test, CMV PCR), hearing tests, brain ultrasound and eye fundus examination should be performed. Neurological and auditory follow-up must be extended well beyond the neonatal period because the occurrence of neurosensory sequelae may be delayed. Oral valganciclovir is the recommended treatment in moderate or severe congenital CMV infections for a period of 6 weeks to 6 months; such treatment requires regular monitoring because of its possible side effects.

ABSTRACT

OBJECTIVE: To define the predictive value (PV) of known prognostic factors of fetal infection with Cytomegalovirus following maternal primary infection <14 weeks of gestation, at different time points of pregnancy: the end of the second trimester; following prenatal magnetic resonance imaging (MRI) at 32 weeks of gestation; and using all ultrasound scans performed in the third trimester (US3rdT). DESIGN: A retrospective study. SETTING: Reference fetal medicine unit. POPULATION: Sixty-two fetuses infected <14 weeks of gestation. METHODS: We defined second-trimester assessment (STA) as the combination of ultrasound findings <28 weeks of gestation and fetal platelet count at cordocentesis. Three groups were defined: normal, extracerebral, and cerebral STA. MAIN OUTCOME MEASURES: For each group, the PV of STA alone, STA + MRI, and STA + US3rdT were assessed retrospectively. Outcome at birth and at follow-up were reported. RESULTS: The STA was normal, and with extracerebral and cerebral features, in 43.5, 42.0, and 14.5%, respectively. The negative PV of normal STA and MRI for moderate to severe sequelae was 100%. The residual risk was unilateral hearing loss in 16.7% of cases. Of pregnancies with cerebral STA, 44% were terminated. Following extracerebral STA, 48% of neonates were symptomatic and 30% had moderate to severe sequelae. In those cases, the positive and negative PV of MRI for sequelae were 33 and 73%, respectively. STA + US3rdT had a lower negative PV than MRI for symptoms at birth and for moderate to severe sequelae. Any false-positive findings at MRI were mostly the result of hypersignals of white matter. CONCLUSIONS: Serial assessment in the second and third trimesters by ultrasound and MRI is necessary to predict the risk of sequelae occurring in 35% of pregnancies following fetal infection in the first trimester of pregnancy. TWEETABLE ABSTRACT: Serial ultrasound prognostic assessment following fetal CMV infection in the 1st trimester is improved by MRI at 32 weeks.

ABSTRACT

Three cases of Bacillus cereus infection or colonization occurred in the same region in France, and milk from the milk bank was suspected as a possible common source of contamination. All Batches delivered to the three cases complied with the requirements of the bacteriological reference method recommended by good practices guidelines. Still, a retrospective analysis with a more sensitive method showed one batch to contain B. cereus, however straincomparison revealed no epidemiological link betweenisolates from patients and those from the milk. Consequently, in accordance with the precautionary principle, we developed a new sensitive method for the screening of pasteurized milk for pathogenic bacteria. From January 1 to August 31, 2017, 2526 samples of pasteurized milk were prospectively included in the study. We showed that a 20 mL sample of pasteurized milk incubated for 18 h at 37 °C under aerobic conditions was favoring the detection of B. Cereus. The nonconformity rate was 6.3% for the reference method and 12.6% for the improved method (p < 0.0001). Nonconformity was due to the presence of B. cereus in 88.5% of cases for the improved method and 53% of cases for the reference method (p < 0.0001). Thus our new method is improves the microbiological safety of the product distributed and only moderately increases the rate of bacteriological nonconformity .

ABSTRACT

OBJECTIVES: Congenital chylothorax is a rare disease and prognostic factors are key element in properly informing parents. This study aimed at determining the prenatal factors associated with neonatal survival in a cohort of liveborn infants with congenital chylothorax. STUDY DESIGN: Observational monocentric cohort study including all liveborn neonates consecutively admitted for congenital chylothorax. RESULTS: Neonatal mortality was 32% (16/50). Prematurity (or birth weight), persistence of hydrops at birth and the absence of thoracoamniotic shunt procedure were significantly associated with mortality, whereas prenatal diagnosis of pleural effusion, side of pleural effusion, hydrops fetalis and amniodrainage were not. In case of prenatal diagnosis of hydrops fetalis, the reversal in utero of hydrops fetalis was significantly associated with survival (P=0.001). In case of thoracoamniotic shunting, the interval between thoracoamniotic shunting intervention and delivery was significantly longer for patients who survived (P=0.03). CONCLUSIONS: Thoracoamniotic shunting and reversal of hydrops significantly improves survival, whereas prematurity worsened outcome of liveborn infants with congenital chylothorax. Our data also suggest that the interval between thoracoamniotic shunting and birth appears to be crucial; the longer the interval, the more likely is the reversal of antenatal hydrops and neonatal survival.
