Allergy was originally defined in 1906 in 1906 by Clemens von Pirquet as 'altered reactivity' to denote the different reaction which occurs on second exposure to an antigen due to the formation of antibodies, when compared to the first exposure. The term atopy decribes the clinical presentation of Type I hypersensitivity, which include asthna, eczema, hay fever and urticaria.... |
Sick neonates often require periodic small volume transfusion(10mg/kg) to replace blood draw for laboratory monitoring during their hospital stay. The effect of packed red cell transfusion on the hematocrit, potassium, ionized calcium, acid base status, glucose and indirect bilirubin was investigated in 25 transfusions. Analysis of transfused blood by the age of the red cells, older red cells (more than... |
Obesity is associated with an impairment of the hormone secretion elicited by all stimuli known to date, but the basic mechanism of this alteration is unknown, To determine whether obesity is associated with a chronic state of tonic somatostatin, several tests with growth hormone stimuli such as GHRH (1㎍/kg), clonidine (150㎍/m2) and Resular insulin (0.1U/kg, subcutaneously), to obese subjects and... |
Failure to thrive(FTT) is defined when the weight of a child is below 3rd percentile or when there is sudden weight loss in history. If organic cause of the weight loss is not found, it is called non-organic failure to thrive (NETT). Relatively little attention has been paid to NFTT in Korea for various reasons and the incidence is... |
The clinical studies were performed on 304 patients with heart disease who had been received corrective heart surgery at Kosin Medical Center from July, 1984 to December, 1991. The results were follows : 1) Out of 304 patients, 162 cases (53.3%) were male and 142 cases (46.7%) were female and sex ratio was 1.15 : 1.35 cases (11.5%) had clinical cyanosis and... |
To study the site of release and factors affecting the releases of the atrial natriuretic peptide (ANP) in the pediatric patients, we measured the plasma ANP concentrations in 23 normal healthy children, 19 patients with congestive heart failure and 16 patients with cardiac disease undergoing diagnostic cardiac catheterization. The following results were obtained. 1) The plasma ANP concentrations of the vein (226.3¡¾74.9... |
Ultrasonic evaluation of the pylorus was performed in a group of 22 infants clinically suspected of having Congenital Hypertrophic Pyloric Stenosis (CHPS), from march 1990 to July 1991. In every case the diagnosis of CHPS was confirmed by surgery. Ten normal babies served as the control group. 1) In CHPS group, the mean age on admission was 36.7¡¾16.4 days, and male... |
The hemodynamic feature of the tetralogy of Fallot (TOF) is best characterized by equality of left and right ventricular peak systolic pressure. The interventricular septum is flattened and thickened. Even after the right ventricular pressure is normalized in the postoperative period, the morphological abnormality continues for some time. We have analyzed the morphological changes of the IVS echocardiographically after total... |
To elucidate the clinical characteristics of childhood onset systemic lupus erythematosus (SLE), we carried out a retrospective reivew on medical records of fourteen patients who were diagnosed as SLE on the base of 뱓he 1982 revised criteria for the SLE?(by american Rheumatism Association) at the Department of pediatrics, Hanyang University Hospital from January 1980 through August 1992. The results were summerized... |
Primary cutaneous aspergillosis is rare. In this report we describe primary skin infection by Aspergillus in 9 children with leukemia. The skin lesion was characterized clinically by erythematous macule and papule associated with pain and itching, followed by a rapid progression to ulcer and central black eschars with raised erythematous border at the site of venipuncture, insertion of intravenous cannula,... |
Four cases of newborn with tension pneumothorax induced by a conventional ventilator were admitted to our nursery January 1. 1992 to June 30. 1992 and they were managed by high frequency ventilator (Infrasonic Infant Star Venilator). In contrast, four cases of newborn with tension pneumothorax who were continuously on the conventional ventilator, were included as a control group. They were... |
We observed 233 twins and 2 triplets cases among 16,774 newborns delivered at Kwangju Christian Hospital during 5 years from Jan. 1986 to Dec. 1990. The results obtained are as follows : 1) The overall incidence of twin pregnancy was 1 : 72 (1.4%) and that of triplets 1 : z8387 (0.01%). 2) The average male-female sex ratio of twins was 1.06 :... |
Hydranencehaly is an abnormality consisting of complete or almost absence of the cerebral hemispheres, which are replaced by a large fluid-filled cavity. The midbrain and brain stem are relatively intact, and rudiments of frontal, temporal and occipital cortex may be present. We diagnosed it through the evaluation of clinical features, prenatal US (intrauterine pregnancy, 37 wks) and brain CT. Authors have experienced... |
Renal calcifications are a recognized complication of furosemide therapy in premature infants. Particularly in infants with chronic lung disease, the use of this potent diuretic is associated with hypercalciuria, which may predispose the infant to medullary nephrocalcinosis and renal calculi. We experienced two cases of nephrocalcinosis in very low birth weight infants. One had bronchopulmonary dysplasia, pneumonia, patent ductus arteriosus,... |
Neoplasms of the nasophrynx are rare in neonates and infants. The most common nasopharyngeal tumor encountered in this age group is teratoma-neoplasm containing multiple heterotopic tissues. Four histologic types of nasopharyngeal teratoma occur-dermoid, teratoid, true teratoma, epignathing of which dermoid is most frequently seen. We have experienced a case of nasopharyngeal teratoma in a female neonate with signs and symptoms of... |
Prader-Willi syndrome is characterized by infantile hypotonia, mental retardation, hyperhagia, hypogonadism and obestiy. Approximately 60% of all PLW syndrome show an interstitial deletion of chromosome 15, 37% have apparently normal chromosome, and 3.6% have a variety of other abnormalities involving chromosome 15. Diabetes mellitus has been considered a component of PLW syndrome and the incidence is about 7%. We... |
Among the various causes of the left ventricular outflow tract obstruction, endocardial remnant tissue is the least common. A case of a subaortic endocardial remnant tissue is presented. The abnormality was detected in an asymptomatic patient by systolic murmur and was demonstrated by 2-D echocardiograpy and surgery. This structure is attached to mitral anterior leaflet and its microscopic finding was... |
We experienced a acquired bronchial stenosis in a male premature infant who had recurrent postextubation atelectasis of the right lung. Bronchography showed the stenosis of the distal portion of right main bronchus and the proximal portion of intermediate bronchus and autopsy findings showed ill-defined irregulary elevated nodule with fibrotic scarring in the trifurcation of right main bronchus. Endotracheal suction was suspected... |
