The vancomycin dosage regimen is regularly modified according to the patient's glomerular filtration rate (GFR). In the present study, we aimed to assess the usefulness of serum cystatin C (Cys-C) concentration, compared with serum creatinine (SCr) concentration, for predicting vancomycin clearance (CLvcm) in neonates. We retrospectively analyzed the laboratory data of 50 term neonates who were admitted to the neonatal intensive... |

The life expectancy of patients with spinal muscular atrophy (SMA) type I is generally considered to be less than 2 years. Recently, with the introduction of proactive treatments, a longer survival and an improved survival rate have been reported. In this study, we analyzed the natural courses and survival statistics of SMA type I patients and compared the clinical characteristics... |

The Pierre Robin sequence (PRS) is the nonrandom association of micrognathia, cleft palate, and glossoptosis, leading to respiratory and feeding difficulties that appear neurogenic rather than mechanical in causation. Genetic determinants are thought to underlie this functional and morphological entity, based on the existence of Mendelian syndromes with PRS. Here, we demonstrate the association of PRS with trisomy 8p due... |
Purpose : Inflammation plays a potential role in the pathogenesis of bronchopulmonary dysplasia (BPD). Strategies for preventing BPD include respiratory management, antioxidants, nutritional treatment, and others such as anti-inflammatory agents. We aimed to assess the safety, tolerability, and efficacy of montelukast (MK), a cysteinyl leukotriene 1 receptor antagonist, as an add-on therapy in BPD. Methods : In addition to currently available... |

Methods : The medical records of 15 neonates with severe MAS admitted at Yongdong Severance Hospital from 2005 to 2007 were reviewed and analyzed. Seven infants with severe... |
Purpose : To examine whether changes of oxygenation index (OI) by postnatal age were different by the number of surfactant administration, and different between subgroups of survival and death. Methods : From January 2005 to June 2006, preterm infants (n=84) diagnosed as respiratory distress syndrome (RDS) and treated with surfactant and ventilator were included. They were divided into two groups: Group... |
Purpose : We investigated the effects of restricted fluid in the first 7 days of life on the risk of bronchopulmonary dysplasia (BPD) or patent ductus arteriosus (PDA) in very low birth weight (VLBW) infants. Methods : Eighty three VLBW infants who lived more than 28 days were selected. The amount of daily maintenance fluid was determined by calculation of insensible... |
Fetal alcohol syndrome can be suspected in infants born to mothers with a prenatal history of alcohol abuse if the child exhibits characteristic facial features, together with intrauterine growth retardation, multiple neurological abnormalities, and multiorgan defects. If only a few of the above criteria are satisfied, the term fetal alcohol effects is used. We experienced a neonate who presented with... |
Purpose : Children with idiopathic short stature(ISS) are classified on the basis of exclusion criteria. Short stature with normal or increased circulating growth hormone(GH) and low IGF-I levels indicates that partial growth hormone insensitivity(GHI) may play a role in ISS. The present study was performed to investigate whether partial GHI is observed in children with idiopathic short stature and whether... |
Purpose : We previously reported modified bovine lung surfactant YY-38(NewfactanⓇ) had a low surface tension, good hysteresis, and exhibited good pressure-volume curve in animal experiment (J Korean Pediatr Asso 1997;40:771-85). We performed multicenter clinical trial of NewfactanⓇ in neonatal RDS. Methods : Seventy-seven infants with RDS(GA 31.8¡¾2.9 wks and BW 1,809¡¾592 gm) in 4 NICU were enrolled. After administration of... |
Purpose : Pulmonary interstitial emphysema(PIE) is a common and serious complication of mechanical ventilation in infants with hyaline membrane disease. This abnormal collection of gases has two basic roentgenographic features; linear and cyst-like radiolucencies. High positive inspiratory pressure was found to be the most significant parameter associated with development of fatal pulmonary interstitial emphysema. Without prompt conservative management such as lowering peak inspiratory... |
Purpose : In experimental models of meningitis and in children with meningitis, dexametha-sone has been shown to reduce meningeal inflammation and to improve the outcome of disea-se.
