Primary immunodeficiency diseases result from innate defects of immune system. As a consequence, recurrent viral, bactrial, fungal, and protozoal infections of varying severity ensue. Although primary immunodeficiency diseases are relatively rare, intensive study of these disorder has expanded our understanding of immunity. Recent progress in immunobiology and genetics has identified the causes of many of the primary immunodeficiency diseases. Diagnosis... |
Renal tubule and vasa recta are arranged in complex but specific anatomic relationships and the production of a concentrated urine is achieved by countercurrent multiplication mechanism in the renal medulla. This model requires that the ascending thin limb is highly permeable to NaCl but impermeable to water, while the descending thin limb is impermeable to NaCl but highly permeable to... |
Purpose : Measurement of body fat in obese children is useful not only in evaluating health hazard but also in establishing standards of treatment and evaluating the effectiveness of treatment. In the field of clinical and laboratory study, there are various methods with different reliability, propriety, convenience, and expenses. However, the practical value of these studies is limited in Korea,... |
Purpose : Obesity is becoming a serious health problem in schoolage children and adolescents. There are several parameters to estimate obesity such as body mass index(BMI), skinfold thickness, obesity index and weight for height. Each parameter has some advantages and disadvantages. Bioelectrical impedance analysis(BIA) seems to be a simple, reproducible, objective and cost effective method for fat evaluation. But there... |
Purpose : The objective of this study was to test the predictive validity of developmental test for later intellectual development in young children with delayed language development. Methods : The study subjects were 66 children who had presented delayed language development and had an initial developmental test and a follow-up intelligence test. The mean age at initial test was 34.2 months(17-48... |
Purpose : We observed changes in the outcome of very low birth weight infants(VLBWI) admitted to the neonatal intensive care unit(NICU) of Dankook University Hospital(DKUH) in the last six years. Methods : The distribution of birth weight and gestational age, survival rate, neonatal complications, and causes of death for 228 VLBWI who had been admitted to DKUH from 1st January... |
Purpose : We performed this study to evaluate the risk of rehospitalization for respiratory syncytial virus(RSV) infection among premature infants discharged from a neonatal intensive care unit(NICU). Methods : We performed a retrospective study for rehospitalization for RSV infection and risk factors among premature infants who were admitted to NICU and discharged between May 2001 and April 2003 in Wonkwang... |
Purpose : Maternal premature rupture of membrane(PROM) over 24 hours is a risk factor in neonatal sepsis and a main cause of administration to neonatal intensive care unit. Levels of proinflammatory cytokines were studied to diagnose and treat early in newborn infants with sepsis and with a history of maternal PROM. Methods : Interleukin-1β(IL-1β), Interleukin-6(IL-6), Interleukin-8(IL-8), and tumor necrosis factor-α(TNF-α) were... |
Purpose : The optimal timing and the consequences of dexamethasone therapy in chronic lung disease remain unknown. The purpose of this study was to determine whether early dexamethasone therapy would reduce the incidence of chronic lung disease and to determine the adverse effects and complications of prematurity associated with such therapy. Methods : Twenty neonates with hyaline membrane disease(dexamethasone n=10, placebo... |
Purpose : This study was undertaken to observe the blood levels of IGF-I and 1,25-(OH)2 Vit. D3 in maternal and neonatal compartments and the effects of IGF-I concentration on intrauterine fetal growth and 1,25-(OH)2 Vit. D3 metabolism in the presence of preeclampsia. Methods : Thirty-four full-term pregnant women with preeclampsia and their newborns(preeclampsia group) and 10 normotensive full-term pregnant women and... |
Purpose : The aim of this study was to determine the role of renal ultrasonography in neonates with isolated preauricular tags. Methods : We performed a retrospective study of 10,997 newborn infants delivered from January 1995 to June 2003 in Wonkwang University Hospital. Nineteen newborns born with isolated preauricular tags were assessed for renal anomalies by performing renal ultrasonography within one... |
Purpose : This study was performed to present out experience of neonatal adrenal hemorrhage (NAH) and to help diagnosis and management of NAH. Methods : We conducted a retrospective study on 14 neonates diagnosed as NAH from January 1993 to August 2002 at Hallym Medical Center. Their clinical manifestations, risk factors, sonographic findings and progression of NAH were evaluated using... |
Purpose : This study was undertaken to find out a useful method that can predict the true leukocytosis in blood-contaminated cerebrospinal fluid(CSF) due to traumatic lumbar puncture(LP), using white and red cell counts of sanguineous CSF and peripheral blood. Methods : From May 2001 to December 2002, among 1,247 patients presenting symptoms of meningitis who had received LP at Chonnam Hospital,... |
Purpose : In order to clarify the role of Helicobacter pylori(H. pylori) in recurrent abdominal pain, we investigated prospectively the effect of eradication of H. pylori based on symptom improvement in children with recurrent abdominal pain. Methods : Children with recurrent abdominal pain were evaluated with diagnostic upper gastrointestinal endoscopy to rule out peptic ulcer disease, etc. During endoscopy, biopsies were... |
Purpose : Respiratory failure arises from derangements in pulmonary gas exchange. The causes may be classified as due to either lung disease or respiratory pump dysfunction. Problems with lung mechanics is an important cause of acute respiratory failure in children clinically. The aims of this study were to survey the cause and prognosis of children diagnosed with acute respiratory failure... |
Purpose : Kawasaki disease is a multisystemic inflammatory vasculitis and associated with neurologic features such as aseptic meningitis. High-dose intravenous immunoglobulin(IVIG) is used to treat Kawasaki disease and generally considered to be safe, but rare cases of aseptic meningitis with unknown etiology have been reported. The aseptic meningitis associated with Kawasaki disease was compared with meningitis as the adverse reaction... |
Purpose : Kawasaki disease(KD) is an important acute febrile systemic vasculitis disease. Various cytokines have been studied to evaluate the pathogenesis of vascular injury. Some cytokines have been implicated for vascular injury, but there has been no direct evidence. We compared cytokine profiles of KD with Henoch-Sch nlein purpura(HSP), and febrile infections. Methods : We investigated the serum concentrations of... |
Vocal cord dysfunction is a recently described entity in which paradoxical adduction of the vocal cords produces airflow obstruction at the level of the larynx. Recurrent wheezing results, which may imitate asthma. Inspiratory closure of the cords can also cause stridor, commonly misdiagnosed as an upper airway obstruction of undefined cause. The acute presentation is often dramatic and has led... |
In Kawasaki disease, arthritis may occur, generally affecting the hands, knees, ankles, or hips. Operations have not usually been needed. We report a case of Kawasaki Disease with multiple septic arthritis which was caused by S. pneumoniae and which needed athrotomy with drainage for both hips, both knees, and both ankle joints. A two year, ten-month-old girl was admitted to... |
Tuberous sclerosis(TS) is known to be associated with multi-organ involvements, such as neurologic, renal and cardiac abnormalities. Abdominal aortic aneurysms in children and young adults are uncommon, however, some have been observed in patients with TS. We present an 8 month-old female patient with TS who developed aortic aneurysm and underwent successful surgical management. Since an aortic aneurysm is potentially... |
