Respiratory disorders and hospitalization rates during the second RSV season in preterm infants who received palivizumab prophylaxis during their first RSV season
No full textThis prospective study evaluated the frequency and severity of respiratory symptoms during the second respiratory syncytial virus (RSV) season in an Italian cohort of preterm infants (≤35 weeks) who had received palivizumab prophylaxis in their first year of life (October 2004-April 2005) and who had not previously been hospitalized for RSV-induced lower respiratory tract infection (LRTI). Infants were evaluated at enrolment (May-September 2005), in October/November 2005 and in April 2006. The occurrence of any respiratory episode, the rate of hospitalization for respiratory-related LRTI, total length of stay in hospital, physician-documented recurrent wheezing (≥3 physician-documented episodes of wheezing) and use of airway medication/antibiotics were recorded during follow-up. All infants had prior palivizumab prophylaxis during their first RSV season. In the total evaluable population (n=260), 32.3% of infants experienced at least one respiratory episode, 3.8% required short hospitalization because of LRTI, 8.5% had physician-documented recurrent wheezing, and 48.8% required airway medications/antibiotics during follow-up. In this study the rate of airway morbidity, hospitalization and physician-documented recurrent wheezing during the second RSV season was low among preterm infants who had received prior palivizumab prophylaxis
Human milk fortifiers in very low birth weight infants
No full textThe use of HMF remains an important option and has become common practice in all neonatal intensive care units. However, optimal composition of fortifiers is still undefined and more data are needed on safety and long-term benefits. Further research should be directed toward comparisons between different proprietary preparations, evaluating both short-term and long-term outcomes and adverse effects, in search of the best method of fortification
Typical Crossmodal Numerosity Perception in Preterm Newborns
No full textPremature birth is associated with a high risk of damage in the parietal cortex, a key area for numerical and non-numerical magnitude perception and mathematical reasoning. Children born preterm have higher rates of learning difficulties for school mathematics. In this study, we investigated how preterm newborns (born at 28-34 weeks of gestation age) and full-term newborns respond to visual numerosity after habituation to auditory stimuli of different numerosities. The results show that the two groups have a similar preferential looking response to visual numerosity, both preferring the incongruent set after crossmodal habituation. These results suggest that the numerosity system is resistant to prematurity
Conservative management of preterm premature rupture of membranes < 30 weeks of gestational age: Effectiveness of clinical guidelines implementation strategies
No full textObjective: To compare obstetrical and neonatal outcomes in patients with p-PROM (preterm premature rupture of membranes) at less than 30 weeks of gestational age before and after the application of protocols developed on the basis of international guidelines and to identify local barriers and strategies for their implementation. Study design: Single and twin pregnancies with p-PROM < 30 weeks of gestation without signs of infection were retrospectively collected. The population was divided in two groups. Group A contained patients treated before the introduction of the protocol, hospitalized from the day of the p-PROM to delivery and treated according to clinicians’ practice. Group B included patients managed according to a standardized protocol, treated with home care management under strict surveillance, after 48 h of hospitalization. Results: 19 women with 21 newborns in group A and 22 women with 26 newborns in group B were enrolled. Maternal characteristics and p-PROM gestational age were comparable. In group A we observed minor latency time from diagnosis to delivery (1.6 vs 6.5 weeks, p < 0.001) with lower gestational age at delivery (25.8 ± 2 vs 30.7 ± 4.2 weeks, p = 0.00) and lower newborn weight (859 ± 268 vs 1511 ± 917 g, p = 0.002). Concerning neonatal outcomes, in group A there were lower Apgar score at 1 min (4.0 ± 2.1vs 6.3 ± 2, p = 004), longer hospitalization (42 ± 38 vs 68 ± 38 days, p = 0.05) and, even if non statistically significant, major rate of neonatal mortality (11,5% vs 19%, p = 1.00) and of neonatal complications (need of neonatal intensive care unit, sepsis, bronchopulmonary dysplasia, retinopathy of prematurity, mechanical ventilation). Postnatal follow-up showed comparable outcomes at 24 months of correct age. Conclusions: Educational and interdisciplinary meetings, along with group performance audit and standardization of procedures are successful strategies to implement guidelines application. Applying this strategy, we developed a protocol according to international guidelines for the treatment of early onset p-PROM based on a standardized conservative management at home, achieving better results compared to hospital management in terms of latency, gestational age at delivery, neonatal weight and neonatal hospitalization

Neurodevelopmental outcomes of premature infants with bronchopulmonary dysplasia
No full textBronchopulmonary dysplasia (BPD) is a chronic lung disorder common among very preterm infants affecting significantly not only mortality and morbidity but also neurodevelopmental outcomes. This review aims to identify the short and long-term neurodevelopmental outcomes of infants with BPD, considering that the new definition of BPD allows to relate severity of BPD with greater risk of developmental delay
Renal Failure of the Surviving Fetus After Intrauterine Death of the Co-Twin
No full textTwin pregnancies are considered at a higher risk for fetal mortality than singleton pregnancies. The antenatal death of one of the twins is associated with an increasing rate of cerebral impairment and lesions in other organs in the surviving fetus, especially if the pregnancy is monochorionic. We describe a case of isolate renal failure becoming evident gradually after birth in a surviving twin after the antenatal death of the co-twin. Considering the deleterious effects of vascular disruption in a surviving twin, our findings suggest careful investigation of renal function, even if no intrauterine signs of diminished renal function were previously detected
An Unusual Pneumoperitoneum in an Extremely Low Birth Weight Preterm Newborn
No full textPneumoperitoneum (PP) is a radiological diagnosis, characterized by the presence of air under the diaphragm, that in 90% of cases results from a perforated viscus while in 10% of cases it is not associated to perforation, the so-called non-surgical or spontaneous PP. Spontaneous PP is rare at any paediatric and neonatal age. In the neonatal population, sporadic cases of spontaneous PP have been described, almost invariably following mechanical ventilation. We presented the case of an extremely low birth weight infant (ELBW) with spontaneous PP secondary to pneumomediastinum who has never underwent mechanical ventilation or cardiopulmonary resuscitation.

Urinary aldosterone excretion and renal function in extremely-low-birth-weight infants following acute furosemide therapy
No full textBACKGROUND: Increased activity of the renin-angiotensin-aldosterone system (RAAS) has been reported in the neonatal period. Until now, it has been demonstrated that the RAAS of healthy neonates responds to acute furosemide challenge while no data concerning the responsiveness of RAAS in extremely low birth weight (ELBW) infants are available.
OBJECTIVE: To assess urinary aldosterone excretion (UAE) and renal function in ELBW infants who received diuretics for the purpose of reducing the incidence of chronic lung disease (CLD).
METHODS: Infants with birth weights < or =1,000 g, at high risk to develop CLD, were studied in a prospective observational study. UAE and renal function were investigated before and after administration of furosemide given in a single dose of 2 mg/kg.
RESULTS: UAE and renal function were evaluated in 20 ELBW infants. Diuretic administration resulted in a significant rise in UAE and urinary sodium, potassium and chloride excretion. No change occurred in creatinine clearance, while urine volume increased significantly.
CONCLUSIONS: ELBW infants respond to acute furosemide challenge by increasing urine volume, urinary electrolytes and UAE
