Comparison of Clinical Finding and Mortality Rate in Neonatal Gastrointestinal Perforation due to Necrotizing Enterocolitis and Other Causes / 대한주산의학회잡지

PURPOSE: This study was conducted to compare the clinical features and outcome of neonatal gastrointestinal perforation due to necrotizing enterocolitis (NEC) and other etiologic diseases (non-NEC). METHODS: The medical records of neonates, admitted to the neonatal intensive care unit of Dongsan Medical Center for gastrointestinal perforation between January 1999 and December 2009, were reviewed retrospectively. The admission records for clinical findings and mortality were reviewed and statistically analyzed for both groups. RESULTS: Among 28 neonates, NEC group was 35.7% and the other group (intestinal atresia, malrotation, meconium peritonitis, etc) was 64.3%. The mean gestational age was significantly shorter (32.8+/-4.6 weeks vs. 36.8+/-2.7 weeks, P=0.028) and the mean diagnostic day was significantly later (16.3+/-9.7 days vs. 2.2+/-1.8 days, P=0.001) in the NEC group than that of the non-NEC group. The mortality rate was markedly higher in the NEC group (50%) than that of the non-NEC group (5.6%)(P=0.013). By simple logistic regression analysis, gestational age (OR 0.69, 95% CI: 0.51-0.95, P=0.022) and NEC (OR 17.00, 95% CI: 1.60-181.36, P=0.019) were the significant risk factors to increase the mortality rate. Multiple logistic regression analysis showed NEC (OR 7.70, 95% CI: 0.55-108.06, P=0.130) and gestational age (OR 0.79, 95% CI: 0.58-1.09, P=0.151) were not the significant independent risk factors. CONCLUSIONS: This study found that gestational age was shorter and mortality rate was higher in the NEC group than the non-NEC group. However, after multiple logistic regression analysis, NEC or lower gestational age itself did not increase the mortality rate significantly.

Changes in N-terminal pro-B-type natriuretic peptide in a neonate with symptomatic isolated left ventricular noncompaction / 소아과

We describe here our experience with a neonate presenting with cyanosis, grunting, and cardiome galy, who was diagnosed with isolated left ventricular noncompaction (IVNC) by echocardiography. The patient had high levels of N-terminal pro-B-type natriuretic peptide (NT pro-BNP) and symptoms of heart failure including poor feeding and tachypnea. During the period in which NT pro-BNP levels steadily increased, the patient suffered sudden cardiac arrest despite heart failure management. Following cardiopulmonary resuscitation, cardiac arrest was resolved, NT pro-BNP levels decreased, and all symptoms showed improvement. We consider that assessment of NT pro-BNP with cardiac functional analysis using echocardiography could help in the prediction of disease progress in IVNC.

Cardiovascular Malformation Diagnosed by Echocardiography in Neonates of Diabetic Mothers / 대한주산의학회잡지

PURPOSE: This study was undertaken to investigate the spectrum and the prognosis of neonate with cardiovascular malformation delivered from diabetic mothers. METHODS: From January 2004 to December 2008, 70 neonates born to diabetic mothers who were delivered at Dongsan Medical Center, Keimyung University, and received echocardiographic study between 3rd and 14th days of life to identify the presence of cardiac anomaly were included. Cases combined with chromosomal anomaly were excluded. And follow up results (rate of cardiac operation and mortality) were assessed. RESULTS: Among 67 neonates, 22 cases (32.8%) had combined cardiovascular malformation. They were interventricular septal hypertrophy (10 cases), atrial septal defect (7 cases), significant patent ductus arteriosus (5 cases), ventricular septal defect (2 cases) and tetralogy of Fallot (1 case). Among them, 20 neonates (29.9%) were preterm babies, and 21 neonates (31.3%) were large babies. On follow up echocardiograpic examination between 2 and 12 months of life, all but 2 infants (received cardiac operation due to VSD or Tetralogy of Fallot) was improved spontaneously. And combined extracardiac anomalies were tracheoesophageal fistula (2 cases), imperforated anus (1 case) and corpus callosum agenesis (1 case). Only one preterm baby was dead due to necrotizing enterocolitis, but did not have cardiac disease. CONCLUSION: Pre-existing maternal diabetes was associated with the development of neonatal cardiac anomalies, but the prognosis was good in this study.
