Volume guarantee ventilation (VGV) is an optional ventilation mode which has become the most widely and extensively studied in the last 10 years in premature infants. Nonetheless, theoretical expected endpoints are intriguing and even though VGV has not yet become ‘the’ standard ventilation mode, a great deal of information has been acquired and stored. In our experience, VGV during the course of respiratory distress syndrome is useful and can be considered a standard ventilation mode. Weaning occurs in real time as described earlier, and synchronized intermittent positive pressure ventilation and pressure support ventilation (PSV) seem to be the preferred combined modes. Management during the acute phase requires more care since several sudden changes take place in both the lung mechanics and clinical behavior. The software is designed to protect the lung, and subsequently, sudden changes in lung compliance following iatrogenic procedures such as surfactant administration are powerfully counteracted. VGV has been extensively studied and the proposed algorithm has been found to function as planned. Although the ‘superiority’ of one method over another cannot be demonstrated, the use of new technologies require ‘a staff learning curve’ and homogeneity of treatment, while at the same time other factors, such as patient heterogeneity or illness phase, should be taken into due account.

Early-onset neonatal sepsis (EONS), a serious infection in newborns within 3 days, is challenging to diagnose. The current methods often lack accuracy, leading to unnecessary antibiotics or delayed treatment. This study investigates the role of the frozen section examination of placental membranes and umbilical cord (FSMU) to improve EONS diagnosis in the daily lab practice. This retrospective study reviewed data from 59 neonates with EONS risk factors who underwent FSMU according to our institutional protocol. Concordance between the FSMU and the Final Pathological Report (FPR) was assessed. The FSMU demonstrated a high concordance (Kappa = 0.88) for funisitis diagnosis, with excellent accuracy (98.3%). A moderate concordance was observed for chorioamnionitis stage and grade. The FSMU shows promise as a rapid and accurate tool for diagnosing EONS, particularly for funisitis. This study suggests that the FSMU could be a valuable tool for EONS diagnosis, enabling a more judicious antibiotic use and potentially improving outcomes for newborns.

Background: Periodontal disease and its bacteria can be responsible for pregnancy complications and transmission of periodontal bacteria from mother to newborn., Methods: A salivary swab to 60 healthy, full-term newborns and their mothers was taken immediately after birth. The test was performed with Real Time PCR method to evaluate the expression of the gene through DNA amplification. The species considered were: Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia and Fusobacterium nucleatum ssp., Results: The newborn oral microbiome was composed primarily by saprophytes (98.38 + 4.88%), just like the mothers (98.8 + 3.69%). There was a statistically significant difference of the total microbiological density in newborns and mothers (p = 0.0001). Maternal and neonatal oral microbiome had a correlated total microbiological density only in 33.3% (N = 20/60) of cases. The analysis of the oral microbiome showed a pathological composition only in 12/60 babies (20%). The most frequent detected specie in newborns was Fusobacterium nucleatum (9/12 babies, 75%), as well as for the mothers (53.3%). However, the pathogen was present both in baby and his mother only in 3 dyads. Porphyromonas gingivalis showed the highest association mother-baby (4/12 dyads, 33%). Porphyromonas gingivalis was the pathogen with the highest bacterial load in the 12 mothers. We found a statistically significant difference in the total load of Porphyromonas gingivalis in mothers and babies (p = 0.02)., Conclusions: There was a statistically significant difference in the richness of the microbiome from newborns and mothers. Even comparing the microbiological density in the oral cavity of the individual mother-child pairs, we did not find a significant concordance. These results seem to suggest a low influence of maternal oral microbiome on the richness of the oral neonatal one. We didn't find mother-child concordance (p = 0.0001) in the presence of pathogenic periodontal micro-organisms. Fusobacterium nucleatum was the most frequent specie detected. Porphyromonas gingivalis instead was the bacteria with the higher possibility of transmission. In conclusion in our study maternal oral health doesn't affect healthy, full-term newborns' oral microbiome. Further studies are needed to understand the maternal influence on newborn's oral microbiome and its effects on babies long-term health., (© 2023. Società Italiana di Pediatria.)

Background: Natalizumab is a monoclonal antibody approved for the treatment of patients with relapsing-remitting multiple sclerosis. According to the current clinical recommendations, its use during pregnancy should be carefully evaluated only in women with highly active disease who plan a pregnancy or have an unplanned pregnancy, after accurate counseling about eventual maternal disease relapse due to therapy suspension., Case Presentation: This brief case report describes a case of documented anemia that we observed in a newborn whose mother with relapsing-remitting multiple sclerosis was treated with an extended dosing protocol of natalizumab throughout pregnancy. The newborn received the infusion of erythropoietin every seven days from the fortieth day of life; subsequently, the status of anemia underwent clinical resolution., Conclusions: This case report confirmed that natalizumab can cause disorders of hematopoiesis, including anemia, thrombocytopenia, or pancytopenia, in newborns of patients treated during pregnancy. A multidisciplinary team, including experienced pediatricians and pediatric hematologists, has a critical role in managing newborns delivered by women, being treated with natalizumab for treating relapsing-remitting multiple sclerosis during pregnancy.

Background: Sudden unexpected postnatal collapse of presumably healthy neonates during early skin-to-skin contact is a rare, yet recognized occurrence, associated with a high risk of mortality and morbidity. A survey was conducted in 2012 in 30 delivery wards throughout Piedmont and the Aosta Valley to evaluate the environmental and logistical aspects that could be linked to SUPC. The survey was again conducted in 2016 in 28 delivery wards in Piedmont and the Aosta Valley in order to evaluate organizational improvements introduced after ministerial indications and recommendations by the Italian Society of Neonatology were published in 2014, in light of new findings regarding the phenomenon., Methods: A questionnaire specifically asking about the organization of delivery wards, and surveillance or supervision during early skin-to-skin contact, was sent to all of the hospitals taking part in the survey in both 2012 and 2016. The collected data were elaborated anonymously and the statistical analysis was performed by using the two by two table., Results: In 2012, 28 out of 30 delivery wards in Piedmont and Aosta, with a total of 31,074 newborns out of 35,435, were evaluated in all of the environmental and logistical aspects that might be cause for SUPC to occur. An identical survey was taken again in 2016; 26 out of 28 wards participated with a total of 27,484 newborns out of 30,339. In 2012, early skin-to-skin contact took place immediately in all the delivery rooms in 27 wards, and soon after in the post-partum room in one; in 11 out of 28 wards there was early skin-to-skin contact in the operating theater itself, following caesarean sections (11/26 in 2016). Routine newborn care was given after 3 h in 8 delivery wards (7/26 in 2016); after 2 h in 12 (7/26 in 2016); after 1 h in 2 (4/26 in 2016); after 30 min in 3 (2/26 in 2016); after 10 min in 1 (0/26 in 2016); after 1 or 2 min in 1 (0/26 in 2016) and at any time in one ward (6/26 in 2016)., Conclusion: Periodic surveys of delivery wards are useful for the assessment of all the aspects and risk factors that need to be changed in order to implement safe early skin-to-skin contact.

Introduction: Hepatic hemangiomas (HH) are benign vascular tumors, and when large, may contribute to fetal morbidity/mortality. Chorangiosis is placental villus capillary hypervascularity, probably linked with fetal hypoxia., Case Report: We present a macrosomic stillbirth at 39 + 3 weeks of gestation with congestive heart failure (CHF) and myocardial infarction. A giant right hepatic lobe HH was present, along with placental chorangiosis., Conclusion: A common pathogenetic pathway between congenital HH and placental chorangiosis has not been reported. Our case suggests that the effects of HH and chorangiosis increase the risk of late fetal loss due to the high-output CHF.

Objective: To investigate whether the nature of the decision about receiving neuraxial labour analgesia is associated with breastfeeding initiation success (BIS), defined as exclusive breastfeeding until discharge associated with postnatal weight loss <7% at 60 hours from birth., Design: Single-centre community-based cohort study., Setting: An Italian baby-friendly hospital, from 1 July 2011 to 22 September 2015., Participants: Inclusion criteria: women vaginally delivering singleton cephalic newborns and willing to breastfeed., Exclusion Criteria: women who delivered in uterus-dead fetuses, were single or requested but did not receive neuraxial analgesia. Overall, 775 out of the 3628 enrolled women received neuraxial analgesia., Results: Compared with women who tried to cope with labour pain, those who decided a priori to receive neuraxial analgesia had less BIS (planned vaginal birth: 2121/3421 (62.0%), vs 102/207 (49.3%; p<0.001; risk difference (RD), 12.7%); actual vaginal birth: 1924/2994 (64.3%), vs 93/189 (49.2%; p<0.001; RD, 15.1%)). Multivariable analyses with antelabour-only confounders confirmed both associations (planned vaginal birth: relative risk (RR), 0.65; 95% CI, 0.48 to 0.87; actual vaginal birth: RR, 0.59; 95% CI, 0.43 to 0.80). Although women who requested analgesia as a last resort had less BIS than did those successfully coping with labour pain in the bivariable analyses (planned vaginal birth: 1804/2853 (63.2%), vs 317/568 (55.8%; p=0.001; RD, 7.4%); actual vaginal birth: 1665/2546 (65.4%), vs 259/448 (57.8%; p=0.002; RD, 7.6%)), multivariable analyses with either antelabour-only or peripartum confounders did not confirm these associations (planned vaginal birth: RR, 0.99; 95% CI, 0.80 to 1.23; actual vaginal birth: RR, 0.90; 95% CI, 0.69 to 1.16)., Conclusions: Compared with trying to cope with labour pain, a priori choice of neuraxial analgesia is negatively associated with BIS. Conversely, compared with having successfully coped with pain, requesting neuraxial analgesia as a last resort is not negatively associated with BIS., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Aim: To study the effects of live maternal speaking and singing on physiological parameters of preterm infants in the NICU and to test the hypothesis that vocal stimulation can have differential effects on preterm infants at a behavioural level., Methods: Eighteen mothers spoke and sang to their medically stable preterm infants in their incubators over 6 days, between 1 and 2 pm. Heart rate (HR), oxygen saturation (OxSat), number of critical events (hypoxemia, bradycardia and apnoea) and change in behavioural state were measured., Results: Comparisons of periods with and without maternal vocal stimulation revealed significantly greater oxygen saturation level and heart rate and significantly fewer negative critical events (p < 0.0001) when the mother was speaking and singing. Unexpected findings were the comparable effects of maternal talk and singing on infant physiological parameters and the differential ones on infant behavioural state., Conclusion: A renewed connection to the mother's voice can be an important and significant experience for preterm infants. Exposure to maternal speech and singing shows significant early beneficial effects on physiological state, such as oxygen saturation levels, number of critical events and prevalence of calm alert state. These findings have implications for NICU interventions, encouraging maternal interaction with their medically stable preterm infants., (©2013 Foundation Acta Paediatrica.

Background: Nosocomial infections are still a major cause of morbidity and mortality among neonates admitted to neonatal intensive care units (NICUs)., Objective: To describe the epidemiology of nosocomial infections in NICUs and to assess the risk of nosocomial infection related to the therapeutic procedures performed and to the clinical characteristics of the neonates at birth and at admission to the NICU, taking into account the time between the exposure and the onset of infection., Design: A multicenter, prospective cohort study., Patients and Setting: A total of 1,692 neonates admitted to 6 NICUs in Italy were observed and monitored for the development of nosocomial infection during their hospital stay., Methods: Data were collected on the clinical characteristics of the neonates admitted to the NICUs, their therapeutic interventions and treatments, their infections, and their mortality rate. The cumulative probability of having at least 1 infection and the cumulative probability of having at least 1 infection or dying were estimated. The hazard ratio (HR) for the first infection and the HR for the first infection or death were also estimated., Results: A total of 255 episodes of nosocomial infection were diagnosed in 217 neonates, yielding an incidence density of 6.9 episodes per 1,000 patient-days. The risk factors related to nosocomial infection in very-low-birth-weight neonates were receipt of continuous positive airway pressure (HR, 3.8 [95% confidence interval {CI}, 1.7-8.1]), a Clinical Risk Index for Babies score of 4 or greater (HR, 2.2 [95% CI, 1.4-3.4]), and a gestational age of less than 28 weeks (HR, 2.1 [95% CI, 1.2-3.8]). Among heavier neonates, the risk factors for nosocomial infection were receipt of parenteral nutrition (HR, 8.1 [95% CI, 3.2-20.5]) and presence of malformations (HR, 2.3 [95% CI, 1.5-3.5])., Conclusions: Patterns of risk factors for nosocomial infection differ between very-low-birth-weight neonates and heavier neonates. Therapeutic procedures appear to be strong determinants of nosocomial infection in both groups of neonates, after controlling for clinical characteristics.

Background: Recently we demonstrated an increased 2,3-diphosphoglycerate (2,3-DPG) erythrocyte concentration in rat pups subjected to nucleotide-enriched artificial feeding., Design: The present study was carried out to test the hypothesis that a possible increase in 2,3-DPG concentration can also be obtained in human neonates who are fed nucleotide-enriched formula. Preterm neonates born or referred to the neonatal intensive care unit of the G. Gaslini Hospital, Genoa University, with a gestational age >30 weeks and <37 weeks were enrolled in our randomized trial. Recruitment took place within 48-72 hours from birth. Only newborns of mothers deciding not to breast-feed were eligible to be randomized for the supplemented group (FN) or non-supplemented group (RF). Breast-fed newborns were considered the control group (C). The study window (for supplementation and blood samples) was restricted to the first two weeks following birth (from the 2nd (t1) to the 16th (t2) day of life). At the end of our study, only 21 neonates were eligible for statistical analysis., Results: The stimulating action of dietary nucleotides on 2,3-DPG concentration failed to be demonstrated; increases in 2,3-DPG concentration that were observed in newborns fed with nucleotide supplemented formula (FN) were comparable to those observed in newborns fed with regular formula (RF) and breast-fed newborns., Conclusions: The EC recommendation for the amount of nucleotides allowed in formula milk does not seem to be high enough to have positive effects on 2,3-DPG synthesis. Whether this possible 'pharmacological' effect can be achieved by a higher intake of ingested nucleotides and/or a change in the proportions of single nucleotides contained in milk formulas remain interesting end points to be elucidated.

A full-term male infant presented at birth with a hard swelling of the left knee. The lemon-sized lesion was fixed to the underlying knee muscles, while the overlying skin was stretched and shiny; there was no bruit. Radiography, sonography and MRI suggested a soft-tissue tumour. After surgical excision, histology showed the presence of fibrous and mesenchymal tissue, with mature adipose tissue. Fibrous hamartoma of infancy was diagnosed. Among soft-tissue tumours, fibrous hamartoma of infancy is a rare and benign lesion, occurring in the first 2 years of life. The tumour mainly affects the trunk, axilla, and upper extremities. This infant had unique involvement of the knee. The treatment of choice is local excision.

The purpose of this methods paper is to offer pediatricians and nuclear medicine physicians a diagnostic protocol for performing lymphoscintigraphy in newborns that may be useful for enhancing diagnosis and management of newborns with congenital lymphatic abnormalities. Indications for lymphoscintigraphy, choice of tracer, optimal dose, routes of administration, methods of data acquisition, timing, and interpretation of results for newborns are presented and discussed.

We report a female infant with congenital lymphedema, facial anomalies, intestinal lymphangiectasia consistent with a diagnosis of Hennekam syndrome. At birth the patient presented with severe respiratory distress due to nonimmune hydrops fetalis, a congenital chylothorax (CC), and pulmonary lymphangiectasia. Hydrops fetalis may be present in newborns with the Hennekam syndrome. Lymphoscintigraphy can be useful in explaining pleural-pulmonary involvement of this generalized lymph vessel malformation syndrome., (Copyright 2003 Wiley-Liss, Inc.)

We report on a male child with "apple-peel" atresia associated with microcephaly and ocular anomalies. To date, no magnetic resonance imagings have been published. We report on the fourth reported case with this phenotype, but the first to be studied by brain magnetic resonance imaging., (Copyright 2002 Wiley-Liss, Inc.)

Background: It has been largely shown that during the first month of life, in the preterm neonate Hb levels and Hct percentages rapidly decrease, high HbF concentration persists and a high oxygen affinity occurs. Data are needed to establish the level at which 2,3 dyphosphoglycerate (2,3 DPG) interacts with the regulation of oxygen affinity., Subjects and Methods: 24 samples, from eight uncomplicated preterm newborns (34.1 +/- 1.83 GW, 1869 +/- +/- 291 BW) obtained at the same time as those required for the clinical management of the infants, were collected on the 2nd, 7th and 14th day of life. Blood gases, total hemoglobin and hematocrit were obtained from 0.3 ml arterialised capillary blood. Assays of 2,3 DPG were made separately on 0.4 ml venous blood., Results: As expected tHb concentration and Hct percentages significantly decreased from day 2 to day 14 in all eight cases. On the contrary 2,3 DPG and p50 values remained stable. Subsequently throughout the study period all neonates had an increased 2,3 DPG/Hb ratio that was significantly related with p50 at standard conditions (p < 0.05)., Conclusions: Stable 2,3 DPG concentrations during all study period have been detected. The subsequent significant increased 2.3 DPG/Hb, ratio related to increased p50 values, could have a key role in a physiological mechanism aimed to ensure adequate oxygen delivery to the tissues and to counteract the higher oxygen affinity of fetal hemoglobin. A wider sample is needed to validate this hypothesis.

Noonan syndrome was first described over 20 years ago by Noonan and Ehmke. They defined a specific group of nine patients with valvular pulmonary stenosis who, in addition, had short stature, mild mental retardation, hypertelorism and unusual facies. The incidence of Noonan syndrome has been estimated to be between 1 in 1000 and 1 in 2500 live births. The primary biochemical defect in Noonan's syndrome is unknown. We analyzed 9 patients (5 males and 4 females) in an age range of 6 months to 10 years and 3 months with Noonan syndrome. Patients were diagnosed as having the syndrome if they had characteristic facies and a normal karyotype, plus one of the following signs: cardiac defects, short stature or undescended testes. All patients have ocular anomalies (epicanthal folds, ptosis of eyelids, hypertelorism, downslanting palpebral fissures and ocular proptosis). Congenital heart malformations are present in 8 patients and the more frequent cardiopath is pulmonary valve stenosis due to a dysplastic or thickened valve. Short stature is present in 6 patients and 3 of them are actually on treatment with rhGH. A moderate-mild mental retardation is present in 6 patients. Case n. 9 had a syringomyelia and tethered cord. These malformations are rarely reported in Noonan's syndrome.

The case of a girl with Seckel syndrome, born of an epileptic mother who was taking anticonvulsant drugs, is reported. The patient, admitted to our clinic for short stature, presented some signs of Seckel syndrome: microcephaly, a "bird headed" profile with receding chin and forehead and large beaked nose. Microcephaly and a low birth weight are present in Seckel syndrome, but also in the newborn of epileptic mothers who received anticonvulsive drugs. In the present paper the Authors questioned if the described syndrome was caused by the use of antiepileptic drugs during pregnancy, or epilepsy of the mother, or if it was casual.
