Purpose : While the rate of breast-feeding has been rising recently in many countries, it has been gradually falling in Korea. Accordingly, we took a survey in Jeon-ju to discover the actual state of breast-feeding and find a solution. Methods : Eight hundred and sixty-four questionnaires of filled out by mothers who visited the seven local pediatric clinics and the clinic... |
Purpose : Although abnormal developments of cushion and atrioventricular septum have been suggested, the exact mechanism for the development of atrioventricular septal defect is not well known. We aimed to identify the role of cell proliferation and apoptosis on cardiac morphogenesis in trisomy 16 mice(an animal model for Down's syndrome in human). Methods : We examined the difference in cardiac... |
Purpose : Balloon valvuloplasty(BVP) is the treatment of choice for valvular pulmonary stenosis (PS). However, this procedure was usually performed in children older than 2 years. The purpose of the present study was to assess the safety and efficacy of BVP in young infants. Methods : Retrospective analysis of the medical records of 25 infants younger than 6 months of age... |
Purpose : The purpose of this study was to correlate birth weight, skinfold thickness, gestational age, BMI and ponderal index of neonates and maternal status with cord serum leptin concentration. Methods : Sixty newborns were enrolled in this study. Standard growth curves were used to categorize infants as appropriate(AGA), large(LGA), or small for gestational age(SGA). Gestational age, birth weight, length, skinfold... |
Purpose : The effect of surfactant treatment on inflammatory cell populations has not been determined. I evaluated the effect of surfactant treatment on a number and distribution of inflammatory cells in bronchoalveolar lavage fluid(BALF) from the preterm infants who were dependent on mechanical ventilation over the 1st week of life. Methods : This study included 8 preterm infants with respiratory distress... |
Purpose : To determine whether pain control using fentanyl would effectively reduce behavioral distress, physiologic and hormonal responses to postoperative pain and mechanical ventilation in neonates. Methods : Neonates who were admitted to the NICU(neonate intensive care unit) of Kyungpook University Hospital, requiring surgery or mechanical ventilation were evaluated. Twelve neonates undergoing operation were randomised into two groups. After operation, one... |
Purpose : Parenteral nutrition is given to infants who tempararily cannot take oral feeding adequately. A lipid emulsion is added to the parenteral to supply essential fatty acids. In neonatal sepsis, elastase from azuropilic granules of the neutrophils is released and rapidly bound to α1- Proteinase Inhibitor(α1-PI). The lipid emulsion has been noted to markedly inhibit chemotaxis of neutrophils, so... |
Purpose : Allergic inflammation of the lower respiratory tract is a characteristic clinical feature in asthma patients, in which eosinophils play an important role. The activity of eosinophil may be determined by measuring the level of eosinophil cationic protein(ECP) in sputum or serum as a potential marker of the inflammatory severity. Methods : We measured the serum concentrations of ECP... |
Purpose : Ventricular late potentials have been shown to predict malignant ventricular arrhythmia and sudden cardiac death in patients with myocardial infarction and cardiomyopathy. Low amplitude and high frequency potentials at the end of the QRS complex can be detected on the body surface using signal-averaged electrocardiogram(SAECG). This study determines the age-related criteria of SAECG parameters and age-related differences. Methods :... |
Purpose : Thioredoxin is an endogenous antioxidant which directly scavenges reactive oxygen species(ROS) and regenerates oxidatively damaged protein by reducing potential at the redox active disulfide(-Cys-Gly-Pro-Cys-) site. Under oxidative stress, thiredoxin plays a protective and adaptative role by inducing expressions. The aim of this study was to clarify the role of thioredoxin on oxidative neuronal cell injury. We investigated the... |
Purpose : The authors performed this study to find out the associated GI disease and H. pylori infection in children with iron-deficiency anemia(IDA). Methods : Twenty-six children older than 2 years with IDA and no history of insufficient iron intake were investigated from 1994 to 1998. Gastrofiberoscopic examination and biopsy and rapid urease test were performed with serum H. pylori IgG.... |
Graves' disease is a relatively rare endocrinologic disorder in childhood age and often associated with other endocrinologic disorders such as type I diabetes mellitus and Addison's disease etc. Also, it is associtated with non-endocrinologic autoimmune diseases such as systemic lupus erythematosus, myasthenia gravis, idiopathic thrombocytopenic purpura, vitiligo and pernicious anemia. However, idiopathic hypoparathyroidism associated with Graves' disease is very... |
Hinman syndrome is a condition caused by an incoordination between the detrusor and external urethral sphincter during bladder contraction. Manifestations include day-and-night wetting, residual urine, infected urine, vesicoureteral reflux, christmas-tree shaped bladder-wall change, and upper tract damage without neurologic lesion or anatomical obstruction. Recently, this incoordination was postulated to be due to over-compensation of the external sphincter which compensates the... |
Chylothorax is an accumulation of lymphatic fluid or chyle in the pleurual cavity resulting from a leak of the thoracic duct or one of its major divisions. If the loss of chyle persist, life threatening nutritional and immunologic deficiencies ensue. Initial conservative managements consist of tube thoracostomy drainage and dietary modification(low fat diet and total parenteral nutrition). In some refarctory... |
