PURPOSE: To evaluate the perinatal factors that influence the incidence of necrotizing enterocolitis (NEC) in newborns infants (NBI) weighing less than 1,500 g. METHODS: A prospective study that analyzed all infants with birth weight (BW) less than 1,500 g born between January 2006 to December 2010 (n=183). They were divided into two groups, i.e. infants diagnosed with NEC (n=18) and infants without a diagnosis of NEC (n=165), which were compared in terms of perinatal factors that could influence the incidence of NEC. Mean data were compared by Student's t-test or nonparametric tests and percentages of categorical variables were compared by the χ² test. When the variables showed differences between groups, they were analyzed using logistic regression with the dependent variable as the presence of NEC. The statistical package used was SPSS 16.0 for Windows. RESULTS: The two groups were similar in terms of most of the clinical and demographic neonatal and maternal data, except for the presence of preeclampsia (PE), which was higher in patients whose children developed NEC (61.1 versus 35,6%). The presence of PE increased the chance of occurrence of NEC by 2.84 times (95%CI 1.0 - 7.7). CONCLUSION: The only factor that can interfere with the incidence of NEC in infants of very low birth weight was the presence of PE. Awareness of this fact can guide the perinatal team in providing more judicious care regarding the prevention of NEC in this specific population.

The Crohn's disease, a form of inflammatory bowel disease, is frequent in women of childbearing age. Its management requires greater attention during pregnancy. We report a case of refractory Crohn's disease in a pregnant patient that evolued to ileocolectomy at puerperium. The literature regarding pregnant patients with Crohn's disease was reviewed, including counseling of patients and investigation of active disease, and the existing data was summarized on the safety of medications used to treat Crohn's disease in pregnancy and breastfeeding.

Screening for major chromosomal abnormalities can be provided in the first trimester of pregnancy. Screening by a combination of fetal nuchal translucency and maternal serum free human chorionic gonadotropin and pregnancy-associated plasma protein-A can identify 90% of fetuses with trisomy 21 and other major chromosomal abnormalities for a false-positive rate of 5%. This is superior to the 30% detection rate achieved by maternal age and 65% by second-trimester maternal serum biochemistry. A further improvement in the effectiveness of first-trimester screening is likely to be achieved by a risk-orientated two-stage approach. In this approach, the patients are subdivided into a high-risk group, requiring invasive testing; a low-risk group, which can be reassured that an abnormality is unlikely, and an intermediate-risk group (risk of 1 in 101 to 1 in 1000), in which further assessment is performed by first-trimester ultrasound examination (for presence/absence of the nasal bone or presence/absence of tricuspid regurgitation or normal/abnormal Doppler velocity waveform in the ductus venosus), and chorionic villus sampling is performed if their adjusted risk becomes 1 in 100 or more. Those performing first-trimester scans should be appropriately trained and their results subjected to external quality assurance. This process was well established by the Fetal Medical Foundation several years ago and is widely accepted internationally.
