Mean birth weights and percentile charts are given for 161 singleton infants born between 24 and 30 weeks' gestation at the 2nd School of Medicine of Naples. This chart is the first for a Mediterranean population. Our data are similar to those reported from a United Kingdom population and from Japan, suggesting that ethnic differences in birth weight at this gestational age are unimportant.

The perinatal histories of 27 newborn infants with NEC were compared to those of 54 infants of equivalent birth weight who did not have NEC during an 8-year study period to see if possible predisposing factors were independent of the confounding effect of birth weight. No differences were observed in gestational age, degree of intrauterine growth retardation, premature rupture of membranes, perinatal asphyxia, skin temperature at admission, haematocrit, presence or absence of respiratory distress syndrome, umbilical catheter placement, start and type of feeding or presence of positive blood cultures. Prematurity is the greatest risk factor predisposing to the development of NEC and the perinatal problems which precede the onset of NEC are common among all premature infants.

Unlabelled: Increasing recent evidence favors paracetamol use for patent ductus arteriosus (PDA) closure in preterms. Our study aims were (1) to assess efficacy and safety of intravenous (i.v.) paracetamol for PDA closure in a 23-32-week preterm population, as "first-line" (when traditional ibuprofen treatment was contraindicated) or "rescue" treatment (after ibuprofen failed), and (2) to identify predictors of PDA closure. The cumulative efficacy of consecutive cycles of i.v. paracetamol on PDA closure was confirmed after both "first-line" and "rescue" treatment, the overall PDA closure rates being, respectively, 56.7 and 61.1 % (p = 0.7624) after two cycles and 63.3 and 77.8 % (p = 0.2959) after three cycles. No toxicity was apparent after either "first-line" or "rescue" i.v. paracetamol treatment. On multivariate analysis, gestational age (GA) emerged as an independent predictor of PDA closure in the "first-line" i.v. paracetamol treatment group, while clinical risk index for babies (CRIB) score (a patient risk index based on birth weight, GA at birth, sex, patient's temperature on admission, and maximum base excess in first 12 h of life) was an independent predictor of PDA closure failure in the "rescue" group.Conclusion: I.V. paracetamol proved effective in our study population. Randomized control trials (RCTs) are warranted to further investigate the efficacy and safety of i.v. paracetamol for PDA closure in preterms.What Is Known: • Oral paracetamol has been judged as effective as oral ibuprofen for PDA closure in the preterm. • To date, only a handful of non-randomized studies exist to support the effectiveness of i.v. paracetamol in PDA closure. What is New: • Our observations confirm the clinical efficacy of i.v. paracetamol for PDA closure in a very low birth weight (VLBW)/extremely low birth weight (ELBW) preterm population. • Gestational age and CRIB score emerge as independent predictors of PDA closure.

Extrauterine growth retardation (EUGR) seriously affects premature newborns and is related to the impairment of growth during childhood. There are very limited data available concerning the growth outcome of EUGR children. Our aim was to assess the growth outcome in a cohort of children born before 34 weeks of gestation with severe EUGR. This was a retrospective multicenter study, performed in outpatient endocrinology clinic. A total of 103 premature children with weight and/or length below −2 standard deviation score (SDS) of 'intrauterine' growth expectation at the time of discharge from hospital (within 42 weeks of postmenstrual age) were included in the study. The study participants underwent a thorough anthropometric assessment at a mean age of 3.9 years ± 1.7 SD. Of the EUGR children, 12.6 % showed a height below −2 SDS and 7.7 % even below −2.5 SDS. Growth impairment was more common in males than in females (17 vs. 8 %). The prevalence of subnormal weight (below −2 SDS) was 13.6 %, being higher in males than in females (17 vs. 10 %). BMI values below −2 SDS were found in 18.4 % of our study population (22.7 % in males and 12 % in females). The 19.6 % of EUGR children did not catch up in head circumference during early childhood. Length at term was the major predictor of height in childhood ( P < 0.001). Conclusion: A significant proportion of children born prematurely with severe EUGR show growth retardation in childhood thus suggesting the need for a close clinical follow-up to determine their growth potential and implement effective intervention strategies.

This study was performed to prove the applicability of the small-for-gestational age (SGA), appropriate-for-gestational age (AGA), and large-for-gestational age (LGA) classification depending on birth weight to predict percentage body fat (%BF) measured by dual-energy X-ray absorptiometry (DXA) in term and preterm infants. The data of 159 healthy term and preterm neonates (87 boys and 72 girls) with a gestational age at delivery of 38.4 weeks from two longitudinal studies were analyzed. Anthropometry and body composition data were assessed within the first 10 days after birth. Correlations between anthropometric parameters and fat mass measured by DXA were calculated. Prevalences of observations with low, middle, and high %BF measured by DXA were compared between SGA, AGA, and LGA groups, according to sex and gestational age. In term infants, 42.9% of the newborns with less than 10% body fat were classified to be AGA; 9.9% of all AGA newborns had less than 10% body fat. For the whole group, among the ratios investigated, the weight-length ratio (r=0.82) showed the best correlation to fat mass measured by DXA. The %BF at the time of study was higher in girls (14.75%) than in boys (11.95%). In conclusion, traditional classification based on birth weight centiles does not reflect %BF in term and preterm newborns. [ABSTRACT FROM AUTHOR]
