  • Purpose: The incidence of methicillin-resistant Staphylococcus aureus (MRSA) infection has increased in children and in neonates, and is particularly associated with frequent use of central venous catheter in very low birth weight (VLBW) infants. It is known that the morbidity and mortality of MRSA infection are low in neonates, as compared with adults. The objective of this study was to examine the difference in clinical characteristics between VLBW infants that survived and those that did not, a catheter-related bloodstream infection (CRBSI) of MRSA. Methods: Thirty-four VLBW infants had laboratory-confirmed bloodstream infection with S. aureus. We examined the incidence, mortality and morbidity of CRBSI, and predictive factors associated with mortality. Results: Twenty-six infants had same pathogen (24 MRSA, 2 Methicillin-sensitive Staphylococcus aureus) in the blood and in the catheter tip. Eight infants (25.8%) died in the CRBSI and they all had MRSA blood infections. Sex ratio, gestational age, duration between blood collection and identification of pathogens, and WBC and platelet count were not significantly different between patients that died from and patients that survived CRBSI of MRSA. C-reactive protein (CRP) was significantly higher in VLBW infants that died. Mean age of onset and hospital day was earlier (9.1${\pm}$6.6 vs. 26.9${\pm}$20.2; P=0.005) and shorter for patients that died (10.1${\pm}$7.0 vs. 73.0${\pm}$32.4; P=0.000). Two survivors had complications of pyogenic arthritis of the lower extremities and soft tissue infection, respectively. Conclusion: Mortality of CRBSI was likely to be high in VLBW infants and might be anticipated by CRP and early onset of disease.

  • Purpose : This study determined the prenatal and postnatal factors associated with complications and prognosis in premature infants with leukemoid reaction. Methods : We retrospectively reviewed the medical records of premature infants with gestational ages <37 weeks and low birth weights (<2,500 g) who were admitted immediately after birth to the neonatal intensive care unit at the Dongguk University Ilsan Hospital between June 2005 and July 2006. A leukemoid reaction was defined as an absolute neutrophil count (ANC) >30,000/$mm^3$. The infants who had leukemoid reaction comprised the study group, while the remainder of infants made up the control group. The relationships between maternal and neonatal variables and ANC were studied. Results : Leukemoid reaction was detected in 3.1% of the study infants (8 of 252). Factors more frequently associated with infants with leukemoid reaction were as follows: maternal chorioamnionitis, high levels of maternal and infant C-reactive protein, gestational age <37 weeks, birth weight <2,500 g, low Apgar score, prolonged ventilator support, and a high incidence of bronchopulmonary dysplasia (BPD). However, there were no significant differences with respect to the antenatal usage of steroids, the incidences of patent ductus arteriosus, necrotizing enterocolitis, intraventricular hemorrhage, retinopathy of prematurity, and mortality between the two groups. Conclusion : Leukemoid reaction in premature infants was associated with chorioamnionitis and high levels of serum C-reactive protein in mothers and infants, and BPD in infants. These findings suggest that leukemoid reaction is secondary to inflammation caused by infection.

  • To study the clinical profiles and outcome of surgery in infants with esophageal atresia, we reviewed 96 esophageal atresia cases who were treated from April, 1978 to June, 1995. There were 51 male and 45 female infants, a ratio of 1.1:1. The low birth weight(<2500g) patients were 32%. Clinical findings at the time of diagnosis included drooling in 57%, choking in 50%, cyanosis in 38%, respiratory distress in 27% and swallowing difficulty in 20%. Gross classification included 6 cases of type A esophageal atresia(6%), 79 cases of type C(82%), 3 cases of type E (3%) and 8 cases of type F(8%). Associated anomalies occurred in 34 infants(35%). Among them, cardiac anomalies were most common(60%). A primary repair of the defect was carried out in 76 patients with type A or C. A staged operation comprising a repair or gastric tube interposition after gastrostomy was performed in 8 patients. In all 3 infants with H-type, a division of fistula was performed. Esophageal resection and anastomosis was done in 8 infants with esophageal stenosis. In one infant, a gastrostomy was performed and he expired before staged operation. Anastomotic complications included leakage in 16 cases(17%), stricture in 37 cases(39%) and recurrent tracheoesopohageal fistula in 3 cases(3%). The mortality rate was 14% and the leading cause of death was pneumonia. The overall survival rate was 86%, and according to Waterston criteria, the survival rates were 93%, 85% and 58% in class A, Band C, respectively. 75 patients were followed up with median follow up 6.4 years. Among them, 93% were uneventful and 7% had frequent pneumonia.
