Prophylactic Use of a Probiotic in the Prevention of Colic, Regurgitation, and Functional Constipation: A Randomized Clinical Trial

IMPORTANCE Infantile colic, gastroesophageal reflux, and constipation are the most common functional gastrointestinal disorders that lead to referral to a pediatrician during the first 6 months of life and are often responsible for hospitalization, feeding changes, use of drugs, parental anxiety, and loss of parental working days with relevant social consequences. OBJECTIVE To investigate whether oral supplementation with Lactobacillus reuteri DSM 17938 during the first 3 months of life can reduce the onset of colic, gastroesophageal reflux, and constipation in term newborns and thereby reduce the socioeconomic impact of these conditions. DESIGN A prospective, multicenter, double-masked, placebo-controlled randomized clinical trial was performed on term newborns (age <1 week) born at 9 different neonatal units in Italy between September 1, 2010, and October 30, 2012. SETTING Parents were asked to record in a structured diary the number of episodes of regurgitation, duration of inconsolable crying (minutes per day), number of evacuations per day, number of visits to pediatricians, feeding changes, hospitalizations, visits to a pediatric emergency department for a perceived health emergency, pharmacologic interventions, and loss of parental working days. PARTICIPANTS In total, 589 infants were randomly allocated to receive L reuteri DSM 17938 or placebo daily for 90 days. INTERVENTIONS Prophylactic use of probiotic. MAIN OUTCOMES AND MEASURES Reduction of daily crying time, regurgitation, and constipation during the first 3 months of life. Cost-benefit analysis of the probiotic supplementation. RESULTS At 3 months of age, the mean duration of crying time (38 vs 71 minutes; P < .01), the mean number of regurgitations per day (2.9 vs 4.6; P < .01), and the mean number of evacuations per day (4.2 vs 3.6; P < .01) for the L reuteri DSM 17938 and placebo groups, respectively, were significantly different. The use of L reuteri DSM 17938 resulted in an estimated mean savings per patient of €88 (US

Two mutations in surfactant protein C gene associated with neonatal respiratory distress.

Optimal nutrition is one of the most important aspects in the care of pre-term infants, especially for the gestationally youngest ones. These infants should receive a supply of nutrients that can sustain growth similar to that of a third trimester normal foetus. Traditional pre-term formulas do not ensure an optimal protein supply except when fed at high volumes, with an excess of fat and carbohydrates. Formulas with a protein content of 2-2.5 g 100ml(-1) and a protein/energy (P:E) ratio of less than 3g 100 kcal(-1) are not the best choice for the very low birth weight (VLBW) infants. We have tested a new formulation designed for the nutrition of the VLBW infants that is characterised by a protein content of 2.9 g 100ml(-1) and a P:E ratio of 3.5 g 100 kcal(-1). The milk formula was well tolerated and associated with better weight gain compared with fortified breast milk (18.1 vs. 15.2 g kg(-1)day(-1); p=0.0015). These results were obtained with a noticeably lower fluid supply (157 vs. 177 ml kg day(-1); p<0.0001) and lower energy intake (130 vs. 151 kcal kg(-1)day(-1); p<0.0001). Infant length and head circumference did not differ significantly between groups. Currently, the use of a formula with a P:E ratio of 3.5 g 100 kcal(-1) appears to be safe and to represent the best choice available for the gestationally youngest infants.

Universal Cranial Ultrasound Screening in Preterm Infants With Gestational Age 33-36 Weeks. A Retrospective Analysis of 724 Newborns

BACKGROUND Sickle cell disease is the commonest haemoglobinopathy in Africa, the Middle East and India. In recent years, its incidence has increased dramatically also in Europe and North America because of the high rate of migration of people from endemic areas. From January 2009 to January 2010 the number of foreign residents in the province of Ferrara (Italy) increased by 12.2%: most of the immigrants were from countries at high risk of sickle cell disease. Since neonatal screening and prophylactic penicillin in early childhood could reduce mortality by 10 years of age to less than 2%, the aim of this study was to establish a neonatal screening programme for haemoglobinopathies in Ferrara. MATERIALS AND METHODS First we assessed how many pregnant women underwent haemoglobin analysis by high performance liquid chromatography before or during pregnancy and how many of them were carriers of haemoglobinopathies. Subsequently, we verified the feasibility of neonatal screening for sickle cell disease and other haemoglobinopathies, analysing cord blood by high performance liquid chromatography. Neonates found to be positive were managed by a multidisciplinary team to implement all the appropriate prophylactic and therapeutic measures. RESULTS We found that 59% of women who delivered at the University Hospital of Ferrara, from 2007 to 2009, had undergone high performance liquid chromatography. Of the 41% who were not tested, many were from areas in which sickle cell disease is common. Between September 26th 2010 and January 31st 2012, 1992 neonatal tests were performed and 24 carriers of haemoglobinopathies were identified (16 with HbS, 4 with HbC, 2 with HbE, 1 with HbD Punjab and 1 with HbD-Ouled Rabah); 42.6% of the mothers of these 1,992 neonates had not undergone high performance liquid chromatography during pregnancy. DISCUSSION Currently prevention of haemoglobinopathies in Italy is provided during the pre-conception period but only to patients with abnormal blood counts. Neonatal screening is useful and cost-effective to ensure early diagnosis and appropriate treatment for infants with sickle cell disease or other haemoglobinopathies.

Prevalence and associated factors for agenesis of corpus callosum in Emilia Romagna (1981–2015)

Multiple mutations of surfactant genes causing surfactant dysfunction have been described. Surfactant protein C (SP-C) deficiency is associated with variable clinical manifestations ranging from neonatal respiratory distress syndrome to lethal lung disease. We present an extremely low birth weight male infant with an unusual course of respiratory distress syndrome associated with two mutations in the SFTPC gene: C43-7G>A and 12T>A. He required mechanical ventilation for 26 days and was treated with 5 subsequent doses of surfactant with temporary and short-term efficacy. He was discharged at 37 weeks of postconceptional age without any respiratory support. During the first 16 months of life he developed five respiratory infections that did not require hospitalization. Conclusion. This mild course in our patient with two mutations is peculiar because the outcome in patients with a single SFTPC mutation is usually poor.

Clinical analysis of spontaneous startles in preterm neonates via sensor networks

BACKGROUND Cranial ultrasonography is a useful tool to detect intracranial lesions in premature neonates at risk. Our primary aim was to determine the number of patients with abnormal cranial ultrasonography. Secondary aims were to evaluate the usefulness of universal cranial ultrasonography screening in moderately preterm infants. METHODS All infants born from 2007 to 2012 at the University Hospital of Ferrara (Italy), with gestational age of 33-36 weeks, were included in the study. Cranial ultrasonography findings were retrospectively classified into nonsignificant and significant. RESULTS All the 724 babies born were screened. Intracranial lesions were in 13% of neonates (3.7% at 36 weeks to 27.1% at 33 weeks of gestational age). Babies born at 33-34 weeks of gestational age were four times more likely to have an abnormal cranial ultrasonography than those at 35-36 weeks. Statistical analysis revealed no association between cranial ultrasonography abnormalities and being small for gestational age or mode of delivery. A significant association was present between the presence of head circumference less than the third percentile, the need for ventilation or surfactant, low Apgar index at fifth minute, and neurological abnormalities. The presence of at least one considered risk factor increases the probability of cranial ultrasonography abnormalities twice in infants born at 33-34 weeks and 15 times in born at 35-36 weeks. CONCLUSIONS A considerable number of infants born between 33 and 36 weeks have cranial ultrasonography abnormalities. We suggest that screening should be performed or at least that a uniform protocol should be developed for the early detection of all significant cranial ultrasonography abnormalities.

Agenesis and hypoplasia of the corpus callosum (ACC and HCC) are heterogeneous group with a large variation in published prevalence based on few population based studies. The aim of this work is to describe prevalence, associated factors and other malformations present in cases with either agenesis or hypoplasia of the corpus callosum, using a population-based database of all malformations diagnosed in Emilia-Romagna, Italy, (the Emilia-Romagna Registry on Congenital Malformations, IMER). This registry links and integrates hospital discharge records, birth certificates with cases reported by referral clinicians to identify all structural malformations diagnosed within one year of life regarding live birth, fetal death or termination of pregnancy due to fetal malformations (TOPFA). During the study period (1981-2015) the number of cases with ACC or HCC was 255, in a reference population of 1,023,784 live births, giving an overall prevalence of 2.49 per 10,000 (1.47 per 10,000 only live birth). After 1996, with the inclusion of TOPFA in IMER registry, the overall prevalence rate increase significantly from 1.42 to 3.03 cases per 10,000 birth (p-value<0.001). Prenatal diagnosis was made in 192 cases (75.3%), at a median gestational age of 20.7 [IQR: 19.71-22.71]. Termination of pregnancy occurred in 105 of the 255 cases (41,2%). Where a prenatal diagnosis was available, 55% of cases ended in TOPFA (105/192), with higher prevalence of cases associated to central nervous system malformations and multiple birth defects, and median gestational age at diagnosis significantly less than in live birth cases (20.3 vs 29 weeks). Agenesis/hypoplasia ratio was 5.7 (217/38). The most frequently associated malformations were musculoskeletal. Trisomies were the most frequent chromosomal anomalies, in particularly trisomy18 and 13 (respectively 9/32 and 4/32 cases). Our study showed an increased risk for male infants (RR of 1.68, RR 95% CI 1.19-2.37). No differences were detected analyzing maternal age and ethnicity, and the increased risk associated to preterm birth disappeared when compared with other malformed infants. This is one of the few population based studies dealing with prevalence of agenesis and hypoplasia of corpus callosum. Prevalence is still debated, but this study adds comprehensive data, in particular inclusion of TOPFA cases. Early prenatal diagnosis, not always possible, could be crucial for decision making regarding continuation of pregnancy.

Universal Head Ultrasound Screening in Full-term Neonates: A Retrospective Analysis of 6771 Infants

Spontaneous startle represents a complex motor pattern, consisting of sudden and jerky movements, which typically occurs during quiet sleep in fullterm and preterm neonates. It has been studied as an endogenous behavior by focusing on its potential contribution to an early diagnosis of central nervous system (CNS) dysfunctions. This paper aims to develop and validate an automated and non-invasive method for inferring spontaneous startles in preterm neonates. Such inference relies on measurements gathered via a hypo-allergenic pad containing a matrix of networked sensors able to measure pressure over time. The measurements gathered by sensors are processed to determine spatiotemporal features allowing to infer spontaneous startles and discriminate them from other behaviors, as well as to identify anomalies and atypical patterns possibly related to CNS issues. Preliminary results based on measurements will be presented, showing the potential benefits of the proposed method in spontaneous startle recognition.
