Purpose : Patent ductus arteriosus, derived left to right shunt flows, elevate the pulmonary artery pressure in infants and children and may alter right ventricular afterload thereby right ventricular function. Therefore, we examined the effects of patent ductus arteriosus on the right ventricular systolic time interval in premature infants by non-invasive Doppler echocardiography. Methods : Tweleve premature infants with patent ductus arteriosus were studied... |
Purpose : Cholestylamine has been shown to release chloride ion and absorbs bile acid in the intestine, forming a nonabsorbable complex preventing enterohepatic circulation. The purpose of this study is to clarify the value of cholestylamine and the adequate dosage, in combination with phototherapy, as well as to confirm whether it shorten the duration of hospitalization. Methods : Total 80 full-term neonates with a... |
Purpose : Premature infants have low serum immunoglobulin G(IgG) levels because IgG is transplacentally acquired, primarily after 32-34 weeks of gestational age. We studied the transplacental transfer of serum IgG in preterm infants. Methods : The IgG levels in the sera were measured by radial immunodiffusion method(Behring nephelometer, Germany). Results : There was a significant difference between IgG concentration and gestational age; the IgG concentration increased... |
Purpose : The prevalence of cytomegalovirus(CMV) depends mainly on socioeconomic status. It is well noted that the prevalence of hepatitis A which is a representive agent of the fecal-oral route has changed since the last 10-20 years. In order to evaluate the time of primary CMV infection in childhood and to get help for interpretating the patterns of infection and prevention, we studied the... |
Purpose : Adriamycin is very important in cancer chemotherapy. Unfortunately, the drug shows cumulative dose dependent cardiotoxicity. The precise mechanism of this remains unclear. It has been shown that adriamycin induces programmed cell death or apoptosis in many tissues. But the role of apoptosis in adriamycin induced cardiotoxicity is uncertain. Methods : Sprague-Dawley rats were divided into four groups of ten animals each. All... |
Purpose : This study was performed to correlate clinical behaviours with either a temporal or frontal site of origin and then to identify behaviours that might have a significant practical value in differentiating a temporal from a frontal focus and thus reduce the need for invasive monitoring. Methods : We analysed 129 seizures that occured during video-EEG monitoring in 13 patients with temporal lobe epilepsy(TLE)... |
Purpose : We evaluated the response to immunomodulation therapy, long-term survival and relapse rate of aplastic anemia during follow-up for more than 1 year. Methods : Twenty-eight children, with moderate to severe aplastic anemia were followed for more than one year and 7 children expired after therapy, were analyzed. Antilymphocyte globulin(ALG) or antithymocyte globulin(ATG) by itself was given to 27 patients, and cyclosporine A(CsA)... |
Purpose : The identification of the ob gene and its adipocyte-specific protein leptin has provided the first physiologic links to the regulatory system controlling body weight. In adults, elevations of serum leptin concentrations correlated closely with the percentage of body fat. This study investigated whether leptin concentrations were elevated in obese children, and the relationship between leptin concentrations and gender and pubertal stage. Methods :... |
Purpose : In this study, efforts have been made to evaluate the sella MRI in 14 patients with growth hormone deficiency to define more clearly the structural abnormalities of the hypothalamohypophyseal axis, examine frequency of these abnormalities, and determine whether a relationship exists between the sella MRI findings and types of endocrine dysfunction. Methods : Sella MRI was performed in 14 patients who were... |
Purpose : The positive rates of allergy skin test of pollens are relatively higher in children in Suwon compared to other areas in Korea. To evaluate the significance of tree pollen as a causative allergen, we undertook this study. Methods : In 252 children with asthma, scratch tests were done with 72 extracts, including 9 tree pollen. Antigen specific serum IgE antibodies were measured... |
Purpose : Antineutrophil cytoplasmic antibody(ANCA) has been identified in various disorders including Wegener' s granulomatosis, microscopic polyarteritis and Kawasaki disease. Measuring this antibody has a diagnostic role. It facilitates monitoring disease activity and may also help understand the pathogenesis of the diseases in which it is found. We investigated the correlation between the hematologic findings and ANCA in acute Kawasaki disease and the diagnostic potential... |
Purpose : High dose intravenous immunoglobulin(IVIG) therapy is effective in reducing the incidence of coronary artery aneurysm in Kawasaki disease(KD) patients, however, the precise mechanisms by which IVIG reverses the immune activation is unknown. Methods : The sera and peripheral mononuclear cells(PBMCs) were obtained from 10 KD patients in the acute stage(24 hrs before) and 24 hrs after one dose of IVIG(2g/kg) treatment. We measured... |
Double-orifice mitral valve is a rare congenital anomaly. Most cases of double-orifice mitral valve are hemodynamically normal and remain symptomless, so that it is usually discovered incidentally in autopsy or during surgical correction of a cardiovascular abnormality. Recently, however, it is increasingly recognized as such, since the echocardiography has gained wide acceptance as a non-invasive diagnostic tool by the M-mode, two-dimensional and color Doppler echocardiogram.... |
Transverse myelitis is a rare complication of systemic lupus erythematosus(SLE) and its prognosis is very poor including death or severe neurologic sequelae. We report a 14-year-old girl with transverse myelitis who was not exactly diagnosed as SLE before the onset of neurologic symptoms. Transverse myelitis was diagnosed based on the clinical presentations, cerebrospinal fluid analysis and MRI findings. We employed aggressive treatment with pulse... |
The appearance of mucoepidermoid carcinoma of the lung during in childhood is an uncommon neoplasm. Symptoms of progressive bronchial obstruction proceed the recognition of this lesion. Adequate surgical resection precludes the need for further radiation therapy or chemotherapy. The patient underwent bronchoscopy to investigate the cause of chronic coughing, which revealed a tumor. Histological examination confirmed the diagnosis of mucoepidermoid... |
Ceftriaxone, a third-generation cephalosporin, is a very potent, broad spectrum antibiotic commonly used in patients with meningitis, osteomyelitis, pyelonephritis, Lyme disease and many other severe infectious diseases. Up to 46% of those receiving this antibiotic develop gallbladder sludge. Most of them are asymptomatic, but a small proportion may develop right upper quadrant pain, nausea, vomiting and even cholecystitis. We report... |
Neonatal hyperthyroidism is a very rare disorder occurring typically in the offspring of patients with Graves' disease or chronic thyroiditis. It is caused by the transplacental passage of thyroid stimulating antibodies(TSAb) from the mother to the fetus. There has been few reports of neonatal hyperthyroidism associated with congenital anomalies. We experienced a case of neonatal hyperthyroidism with unilateral microtia and agenesis of external auditory canal... |
Abnomalities in the production and transport of airway secretions play an important role in the pathophysiology of asthma. Segmental atelectasis as a complication of asthma, is relatively common in children. On the other hand, massive atelectasis such as the collapse of one lung is a very rare occurence. We report a seven-year-old male asthmatic patient with right lung collapse caused by mucoid impaction. Fourteen... |
Meckel-Gruber syndrome is a multiple malformation syndrome featuring occipital meningoencephalocele, multicystic dysplasia of kidney, cystic and fibrotic change of liver, polydactyly, and other characteristics inherited by the autosomal recessive trait. We exprienced a case of Meckel-Gruber syndrome in a newborn male diagnosed clinically and confirmed pathologically. Abnormalities of the fetus were found prenataly by ultrasonogram, and subsequently the baby was... |
The congenital esophageal atresia with proximal tracheoesophageal fistula is a developmental defect with incomplete septation of the foregut of embryonic period and is often associated with other congenital anomaly. We experienced a case of the esophageal atresia with proximal tracheoesophageal fistula in a 1-day old male patient who was transferred from an obstetric clinic due to respiratory distress soon after birth. The baby was treated... |
