Purpose : We tried to know normal range of auditory brainstem responses in premature and fullterm infants who have no rksk factor during perinatal period and to determine that the abnormal ABR in premature and fullterm infants may predict developmental delay. Methods : ABR evaluations were performed on 283 premature and fullterm infants from NICU of the Asan Medical Center during... |
Purpose : Recurrent apnea of prematurity is a very common and troublesome problem despite treatment with aminophylline, and is often associated with a poor developmental outcome. Recently doxapram, a potent respiratory stimulant in adults, has been used to overcome idiopathic apnea of prematurity. This study was to evaluate the efficacy, safety and optimal dosage of doxapram in idiopathic apnea refractory to aminophylline. Methods... |
Purpose : Auditory evoked potentials(AEP) are sensitive electrophysiological technique which accurately assesses the functional integrity of the auditory pathway in the brainstem. As a test of brainstem function, AEP have the advantages that the procedure is standardized, the results are reproducible, the norms for neonated have been estsblished, and the equipment to perform the test is widely available. Our study... |
Purpose : We have found somewhat high titer of antistreptolysin O (ASO) accidentally when we had delineated normal carrier rate of beta hemolytic streptococci in rural area of Kangwon Province in 1991(1). We would like to know upper limit of normal value of ASO and re-valuated results which might be changed with different geographic areas, age, and prevalent rate... |
Purpose : Recently, a wide application of gastrofiberscopy in the pediatric group have revealed that nodular gastritis is an unique disease in children and associated with Helicobacter pylori. The aim of this prospective study was to investigate the clinical and histologic features in children with nodular gastritis, and to assess corelation between both. Methods : During a period of 44 months(May 1991-December... |
Purpose : Mycoplasma pneumoniae is a common cause of a wide rage of upper and lower respiratory tract infections, especially in children and young adults. Routine laboratory diagnosis of M.pneumoniae infection is based mainly on serology and, to lesser extent, on cultivation. The cultivation of M.pneumoniae, a fastidious microorganism, is time-consuming and may require 1-3 weeks for results. Serological procedures... |
Purpose : constriction or banding of the pulmonary artery tocreate pulmonalry artery stenosis is a palliative procedure designed to limit pulmonary blood flow in congenital cardiac malformation with unrestricted shunt flow from the systemic to pulmonary circuit. Increased pressure-load with the procedure results in ventricular hypertrophy in right ventricle. We studied effects of the pulmonary artery constriction on the right ventricle... |
Purpose : The study objective was to elucidate the possible pathophysiologic mechanism of Ca overload by adriamycin (ADR) which is associated with ADR- induced cardiotoxicity. Methods : The effects of ADR on ionic currents were studied using the whole cell voltage clamp technique in single cardiac myocytes of the rabbit. Results : The magnitude of the inward tail current, recorded at -70mV... |
Purpose : Although the etiology and pathogenesis of child with nephrotic syndrome remains uncertain, it has been suggested from indirect evidence that this syndrome may represent deficiency in T-cell function and abnormal humoral immune response to antigens or immynoglobulin. Children with nephrotic syndrome are susceptible to pneumococcal infection. Now, we performed this study to evaluate pneumococcal anticapsular antibody concentration and... |
Purpose : Because of weternized life style, environmental air pollution and infection, the incidence of childhood diabetes is increasing daily. This study was attempted to evaluate charateristics of childhood diabetes. Methods : We evaluated 117 patients diagnosed with Diabetes at Yonsei and Ewha University College of medicine from 1985 to 1994. Results : 1) The majority of patients were diagnosed as IDDM(86%).... |
Purpose : To investigate the diagnostic significance of urinary growth hormone measurement and compare with the urinary GH values in different methods of urine collection, this study was performed in patients with short stature. Methods : Measurement of urinary GH excretion was performed in 9 children with complete growth hormone deficiency (GCD), in 19 children with partial growth hormone deficiency (GPD)... |
Purpose : This study was performed to be helpful in early diagnosis and treatment of the children with neurologic disorders. Methods : One hundred and eighty-five pediatric patients with neurologic disorder were studied from May 1991 to March 1994, ranging in age from neonate to 15 years old. All patients were imaged with MRI. We observed age and sex distribution, frequency... |
Subacute necrotizing lymphadenitis (Kikuchi's disease) is an increasingly recognized cause of cervical lymphadenitis since it has been described by Japanese doctors in 1972. It generally follows a benign course, when symptoms and signs of the disease are resolved usually within 1 to 6 months. We experienced a case of subacute necrotizing lymphadenitis in a 12 year-old boy with atopic bronchial asthma... |
We experienced a case of partial monosomy 21 ina 9 year and 8 month old boy. He showed mental and growth retardation, others normal appearance except for low set malformed ears. Chromosomal analysis on Giemsa banding with high resolution showed unbalnaced translocation between 10 and 21 chromosomes and the deletion of short arm and centromere of chromosome 21. His karyotype... |
Acrorenal syndrome is congenital anomaly of the limbs and urinary tract of unknown etiology. Acral malformations consist of varying combinations of oligodactyly, ectrodactyly, syndactyly, brachydactyly, polydactyly, and carpal, tarsal, or metatarsal fusions of the hands and feet. Urinary tract abnormalities include unilateral renal agenesis and duplication of the collecting system. The condition is a polytopic developmental field defect(acrorenal field) and... |
Since Brown first descirbed the eosinophilic granuloma in 1960, 45 cases of eosinophilic cystitis have been reported in the literature, including 10 pediatric cases. In Korea, only four adult cases were reported. Eosinophilic cystitis is characterized by severe infiltration o eosinophils into the mucosa, submucosa and muscularis of bladder wall which causes irritative voiding symptoms. This lesions have been frequently... |
Psudohypoaldosteronism is a salt-wasting disease with unresponsiveness to mineralcorticoid and normal renal and adrenal function. Characteristic findings are severe hyponatremia, hyperkalemia and hyperaldosteronemia. We experienced a case of pseudohypoaldosteronism ina 1-day-old female who was presented with abdominal distension. Laboratory data showed hyponatrmia, hyperkalemia, elevation of plasma renin activity and aldosterone concentration and normal renal, adrenal function. We reported a case of... |
