Objective: To determine outcomes at birth and postnatal sequelae of congenital cytomegalovirus (cCMV) infection following maternal primary infection in the first trimester with normal fetal brain imaging at midgestation.
Methods: A retrospective, single-center cohort study was conducted, including all cases of proven cCMV infection following maternal primary infection in the first trimester from 2014 until 2021 and normal fetal brain imaging before 22 weeks of gestation. All pregnancies were followed according to our protocol, which offers amniocentesis at least 8 weeks after the onset of infection, serial ultrasound scans, and a fetal MRI in the third trimester.
Congenital cytomegalovirus (CMV) infection is the main cause of non-hereditary sensorineural hearing loss (SNHL). In order to shed light on SNHL pathophysiology, we examined the auditory pathway in CMV-infected fetuses; the temporal lobe, in particular the auditory cortex, and the inner ear. We investigated both inner ears and temporal lobes of 20 human CMV-infected fetuses at 21 weeks of gestation.

Rates of LP and potential variables associated with LP performance were evaluated.

Italian prospective surveillance cohort data (2003-2022) were used to study the type and duration of IAP according to the timing of symptoms onset of group B streptococcus (GBS) and culture-confirmed EOS cases. IAP was defined "active" when the pathogen yielded in cultures was susceptible.

Methods: Cohort study enrolling neonates born to mothers with SARS-CoV-2 infection in pregnancy. All infants were evaluated at birth.
Introduction: Most infants at risk for cytomegalovirus (CMV)-associated sensorineural hearing loss (SNHL) are unrecognized because of the absence of a universal neonatal CMV screening. The search of CMV-DNA by molecular methods in salivary swabs was demonstrated to be a reliable approach. This study describes the results obtained by carrying out a universal screening for congenital CMV (cCMV) infection including all live-born newborns in three Italian sites, as well as the therapeutic interventions and clinical outcome of the CMV-infected neonates.

We describe a 2-month-old girl with intrauterine and extrauterine growth restriction who presented with an isolated severe anemia requiring red blood cell transfusion, without gastrointestinal symptoms, history of infection, or congenital abnormalities. An abdominal ultrasound revealed a reduced pancreatic thickness and abnormal echogenicity without fat infiltration, further confirmed by MRI.

Clinical manifestations among children are generally less severe than those seen in adults, but critical cases have increasingly been reported in infants less than 1 year of age. We report a severe case of neonatal COVID-19 requiring intensive care and mechanical ventilation, further complicated by a multidrug-resistant Enterobacter asburiae super-infection.

Background: The thermal servo-controlled systems are routinely used in neonatal intensive care units (NICUs) to accurately manage patient temperature, but their role during the immediate postnatal phase has not been previously assessed.
Objective: To compare two modalities of thermal management (with and without the use of a servo-controlled system) immediately after birth.
Study Design And Setting: Multicentre, unblinded, randomised trial conducted 15 Italian tertiary hospitals.
Human parechovirus (HpeV) is an important emerging infection in young infants, able to cause sepsis-like disease and meningoencephalitis, especially in newborns. Among the 19 identified genotypes, HPeV1, 3 and 6 are the most common types involved in human infections; HPeV3 is the type mainly responsible for neonatal infections and for infections involving the central nervous system. Signs and symptoms overlap with those of a bacterial infection and patients are usually treated with broad spectrum antibiotics.

Methods: CMV-specific CD8 + T-cell responses were assessed in neonates with cCMV using QuantiFERON®-CMV assay, within day 14 of life (T0) and during the second month of life (T1). Detection and quantification of CMV DNA in whole blood and urine samples were performed at both time points.
Background: International guidelines lack a substantial consensus regarding management of asymptomatic full-term and late preterm neonates at risk for early-onset disease (EOS). Large cohorts of newborns are suitable to increase the understanding of the safety and efficacy of a given strategy.
Methods: This is a prospective, area-based, cohort study involving regional birth facilities of Emilia-Romagna (Italy).
Skin disinfection with chlorhexidine gluconate has not been standardized in preterm infants. We present 5 cases of chemical burns that occurred within the first 2 days of life in very low birth weight neonates after skin disinfection with aqueous and alcohol-based chlorhexidine solutions.

Clinical evaluation of the Elecsys CMV IgM, IgG, IgG Avidity and COBAS AmpliPrep/COBAS TaqMan CMV (COBAS CMV) assays (Roche Diagnostics AG) in the diagnosis and prognosis of congenital CMV infection was performed. In this study, 150 preselected clinical samples (50 primary infection sera, 50 amniotic fluid [AF] and 50 newborn urine) were processed using Roche serological/molecular CMV-specific tests. Results were compared with those obtained by routine assays (comparator assays).

Methods: We performed a retrospective cohort study of pregnant women with active CMV infection referred to our unit over a 15-year period (January 2000 to December 2014). Non-primary infection was diagnosed on the basis of the results of confirmatory serological and virological tests (avidity test, immunoblotting, real-time PCR-DNA).

Prophylaxis with zidovudine and 3 doses of nevirapine (NVP) is recommended for infants born to HIV-1 infected untreated mothers to prevent HIV-1 mother-to-child transmission. However little is known about NVP pharmacokinetics in neonates, mostly in preterm infants. We performed therapeutic monitoring of NVP plasma concentrations in a 32-week preterm HIV-1 exposed infant born to an infected untreated mother.
