ABSTRACT

PURPOSE: The aim of this study was to identify and assess mortality predictive factors in newborns with necrotizing enterocolitis (NEC) requiring emergency exploratory laparotomy. METHODS: A prospective study of 91 newborns with NEC submitted to exploratory laparotomy was conducted. Clinical outcomes were death and survival 60 days after surgery. Nine variables were analyzed: weight at birth, gestational age, intrauterine growth, sex, gas in the portal vein at abdominal x-ray, pneumoperitoneum, extent of the disease, operative strategies, and extension of bowel resection. Univariate and multivariate analyses were performed to identify mortality predictors. RESULTS: Mean weight at birth was 1,676 +/- 634.8 g, and mean gestational age was 34 +/- 2.8 weeks. Thirty-nine newborns (42.9%) presented intrauterine growth retardation. Operative techniques included bowel resection with enterostomy (80 patients), bowel resection with primary anastomosis (10 patients), and decompressive enterostomy (1 patient). Six deaths occurred caused by co-existing disease. NEC-related mortality rate was 46.15% (42 of 91). CONCLUSIONS: Two variables, intrauterine growth retardation, and diffuse bowel involvement, were predictive of mortality according to both univariate and multivariate analyses. Site of bowel involvement seems to be important mortality predictors in infants with NEC requiring surgery. The size of our population did not allow statistical analysis of this relationship. Further studies should focus on examining this aspect.

ABSTRACT

OBJECTIVES: To evaluate the association between DSM-IV conduct disorder (CD) and school dropout in a sample of students from the third and fourth elementary grades at state schools in the capital of the southernmost state of Brazil. METHODS: In this case-control study, students that dropped out of schools (n = 44) and a control group who continued attending schools (n = 44) were assessed for CD and other prevalent mental disorders, using the Schedule for Affective Disorders and Schizophrenia for School Age Children, Epidemiological Version (K-SADS-E). RESULTS: The prevalence of DSM-IV CD was significantly higher in the school-dropout group than in control subjects (P < 0.001), both in the entire sample and in a subsample including only subjects under age 12 years (P = 0.001). Also, the odds ratio (OR) for school dropout was significantly higher in the presence of DSM-IV CD, even after controlling for potential confounding factors (age, estimated IQ, school repetition, family structure, and income) (P < 0.01). CONCLUSION: Our results extend to children and young adolescents previous findings from studies of older adolescents, suggesting an association between school dropout and CD.
