Italy provides a free voluntary serological screening for toxoplasmosis in pregnancy supported by public health system, as there is an estimated congenital toxoplasmosis rate of 1-2/10,000. The aim ...of this study was to make an inventory of diagnostic and therapeutic protocols in use in Italy in the absence of a national guideline. A semistructured questionnaire was distributed to AMCLI (Italian Association of Clinical Microbiologists) members who were asked to involve other specialists to fill in the form. Data from 26 centers show: a) a general use of the IgG avidity test to solve diagnosis in IgG/IgM positive, pregnant women; b) a widespread attitude to spyramicin antenatal treatment in suspected, unconfirmed maternal infection; c) avoidance of invasive antenatal diagnosis only in suspected early or late (>24 weeks), even confirmed, maternal infection d) fetal diagnosis performed by PCR assays on amniotic fluid; e) variability of both indications and dosage of pyrimethamine-sulfadiazine (P-S) as fetal treatment; f) use of comparative mother and newborn IgG/IgM Immuneblot in most centers; g) no diagnostic tests performed on placenta and cord blood; h) spyramicin is no longer used in congenital infections; i) no P-S-based treatment for children at high risk of congenital infection (late maternal infection) in the absence of diagnosis. As there is the opportunity to test pregnant women for Toxoplasma gondii infection in Italy free of charge, standardized diagnostic and therapeutic national guidelines would focus on a more uniform approach.
Infants born to mothers who seroconverted for toxoplasmosis during pregnancy are at risk of sequelae. In the case of a negative work-up at birth, congenital infection can be ruled out only by ...monitoring the disappearance of maternal immunoglobulin G (IgG) transmitted through the placenta, which can be achieved by regular blood sampling during the first year. To alleviate the discomfort of this follow-up, we developed an indirect enzyme-linked immunosorbent assay to detect specific IgG diffusing passively from the blood through the gingival epithelium by collecting oral fluid on microsponges. To assess the feasibility of the test, 212 patients were first enrolled. Levels of specific IgG in oral fluid were significantly higher in seropositive (n = 195) than in seronegative (n = 17) patients (mean optical densities, 1.145 ± 0.99 versus 0.092 ± 0.127; P < 0.0001). In a population of 93 patients <15 months of age born to mothers who displayed toxoplasmic infection during pregnancy, 70 were free of congenital infection and were followed up until their serology turned negative, and 23 were congenitally infected. The same patterns of IgG were observed in the oral fluid and sera in each group. Using a cutoff of 0.04 (optical density value), the sensitivity and specificity of the test were 67.9% and 80.3%, respectively, and the probability of not having a congenital infection when the test on oral fluid was negative was 99%. Although the performance of the test needs to be improved, oral fluid sampling appears to be a promising tool for monitoring infants with suspected congenital toxoplasmosis.
Objective
To measure the red cell distribution width (RDW) ranges at birth and to evaluate potential association with typical neonatal diseases: patent of the ductus arteriousus (PDA), ...bronchopulmonary dysplasia (BPD), and late-onset sepsis (LOS) mortality.
Methods
Forty-six full-term, 41 preterm, and 35 intrauterine growth restricted (IUGR) infants participated in this retrospective, observational study. RDW was measured before 3 days of life (T0) in all infants, and at first month of life (T1) in preterm/IURG patients.
Results
RDW% mean (standard deviation) at T0 was: 15.65 (1.18) in full-term newborns; 17.7 (2.06) in preterm; 17.45 (1.81) in IUGR. A negative correlation (r = −0.51; P < 0.001) between RDW and gestational age was found. RDW at T1 was: 17.25 (2.19) in the preterm group; 17.37 (2.56) in IUGR group. Fourteen preterm infants reported: 12 PDA, 5 LOS, 4 BPD, and 3 died; 10 IUGR infants had: 4 PDA, 6 LOS, 3 BPD, and 1 died.
RDW of IUGR infants suffering from those pathologies was not statistically different compared with unaffected infants, while preterm newborns with pathologies reported higher RDW: PDA vs. PDA absent: P = 0.008 at T0; P < 0.002 at T1. BPD vs. BPD absent: P < 0.005 at T1. LOS vs. LOS absent: P < 0.005 at T0.
RDW in preterm/IUGR population was associated with early mortality, T0: dead 21.2 (2.7) vs. alive 16.7 (1.7), P < 0.0001.
Conclusion
RDW and gestational age at birth were negatively correlated. High RDW resulted to be an indication of risk for critical newborns. This parameter can be inexpensively and routinely verified and further studies are required to confirm its prognostic role in neonatal pathologies.
Exposure to hypothermia is somehow unavoidable when a baby comes to life. This is the reason why any possible effort should be made by every caregiver involved during birth, from labour to transfer ...into the maternity ward, to reduce it. Hypothermia has widely shown to be related to several neonatal problems, and the risks are more relevant when the babies are born prematurely.
An observational study was conducted in April 2016 to assess the current practises to avoid hypothermia at birth in 20 Italian neonatal units. Each unit introduced local improvements in clinical practice and the same observational study was repeated 1 year later.
A total of 4722 babies were analysed. An overall increase in adherence to local and international recommendations emerged from our study. Significant differences between 2016 and 2017 were found in regard to neonatal temperature at nursery entry (36.3 °C vs 36.5 °C, respectively, p < 0.0001), delayed cord clamping practice > 60″ (48.1% vs 68.1%, respectively, p < 0.0001) and skin-to-skin practice > 60' (56.3% vs 60.9, respectively, p = 0.03). Statistical correlations with the risk of hypothermia were found for delivery room (OR 0.88 (CI 95%0.83-0.94), p < 0.0001) and maternal temperature (OR 0.57 (CI 95% 0.48-0.67), p < 0.0001).
Periodical assessment of the delivery room practice has shown to be effective in improving adherence to the international recommendations. Relationship between neonatal hypothermia and several other variables including the delivery room and mother temperature underlines how neonatal thermoregulation starts immediately after birth. Hence, a multi-disciplinary approach is needed to provide the optimal environment for a safe birth.

Preterm birth is the leading cause of perinatal morbility and mortality in developed countries. Many innovation in neonatology have raised survival rates in the two past decades, but despite progress ...in neonatal intensive care, nutrition and growth of preterm infants are still critical points for neonatologists around the world and extrauterine growth restriction remains a common problem. Since growth is recognized as a major problem, in 2010, the European Society of Pediatric Gastroenterology and Nutrition published recommendations on enteral nutrition for preterm infants. The aim of this review is to revise nutritional needs of premature infants, taking into consideration the recommendations of ESPGHAN and the recent international literature.
Homocystinuria represents a group of hereditary metabolic disorders characterized by an accumulation of homocysteine in the serum and an increased excretion of homocysteine in the urine. The ...infantile form is severe: the main clinical findings are neurologic signs, associated with hematological signs and bone alterations. Immediate restoration of plasma amino acids is the primary goal and early diagnosis is crucial not to delay the onset of possible treatment. We report a case of homocystinuria with early onset: an initial symptomatology was undervalued by the pediatrician with a delay in diagnosis. Despite the therapy, the patient developed tetraventricular hydrocephalus requiring ventricular drainage. In conclusion, we want to remember the necessity to perform a complete metabolic workup in a patient with clinical manifestations suggestive for homocystinuria, and the importance of early recognition of the signs and symptoms of hypertensive hydrocephalus, a possible complication of this condition.
Intrapartum chemoprophylaxis is currently the most effective preventive strategy against the neonatal early-onset group B streptococcal infection. The principal controversies on strategies for ...intrapartum antibiotic administration, possible adverse effects, management of newborn and possible future preventive strategies reported in the literature are considered.
Human cytomegalovirus (HCMV) immediate-early messenger RNA (IEmRNA) in sequential blood samples from 32 pregnant women with primary infection and from 14 congenitally infected newborns was ...qualitatively investigated by nucleic acid sequence—based amplification. IEmRNA was detected in 100%, 75%, 36.3%, 22.2%, and 0% of samples collected 1, 2, 3, 4–6, and >6 months after onset of primary HCMV infection, respectively, showing 83.7% sensitivity and 92.2% specificity, compared with results of quantitative DNAemia (detection of viral DNA in blood). In infected newborns, IEmRNA was positive in 100% of samples collected 1–7 days (median, 1.5 days) and in 46.4% of samples collected 27–260 days (median, 88 days) after birth, showing 75.7% sensitivity and 100% specificity, compared with DNAemia results. IEmRNA was not detected in HCMV-immune individuals with remote or recurrent HCMV infection or in uninfected newborns. IEmRNA determination appears to be a valuable tool for early diagnosis of both primary and congenital HCMV infection
