This report presents 16 cases of neonatal necrotizing enterocolitis NEC). We reviewed the clinical picture and the laboratory results of our patients. According to the presentation time we divided our series in early and late variety, as in the literature previously reported. The risk factors were gestational age of 35 weeks or less, birth weight under 1500 g, low Apgar score, hematocrit higher than 65%, early artificial feeding, umbilical vessels' catheterization and abnormal intestinal colonization with pathogen germs. We consider very valuable serial abdominal X ray pictures and paracentesis for the diagnosis of chirurgic acute abdomen. (An Fac Med UNMSM 11 Epoca 1989; 1 (1-2): 15-18).

618 macrosomic babies in a population of 8,880 live births (6.9%) was studied. For purposes of our analysis considered 500 cases, finding the association of certain maternal and fetal macrosomia factors such as parity and age (43%), gestational age of 39 weeks or more (90%), maternal diabetes (1.9%) male (65%). The application of vacuum extractor was double that of the general population (4 .6%: 2.1%). Macrosomia morbidity was twice the normal newborn weight (28%: 14%). The incidence of asphyxia, meconium aspiration and trauma at birth increased the weight. The neonatal mortality rate in macrosomic was 8%, the cause of death related in particular to fetal size. To improve the prognosis of infant macrosomia, you must establish a pediatric-obstetric combined management aimed at identifying the population at risk and prenatal detection of macrosomia in an attempt to reduce morbidity associa...
