We analyzed the lomgitudinal height and... |
Purpose : Failure of adequate gastric emptying frequently interferes with successful enteral nutrition in infants. Study of gastric emptying in preterm infants has been hampered by the absence of a suitable and, valid technique, but ultrasonic assessment is well tolerated by infants. The aim of this study is to compare gastric emptying rates of breast milk and formula within preterm... |
Purpose : The present study was designed to investigate rotavirus infection by comparing clinical characteristics of the nosocomial infection of rotavirus between preterm and full-term neonates. Methods : The subjects were admitted from May to December, 1996. In 71 preterms, 44 were Rotazyme positive, 27 were negative, and in 321 full-terms, 64 were Rotazyme positive, 257 were negative. We studied the... |
Purpose : To find the anthropometric characteristics of newborn in women with gestational diabetes mellitus(GDM), and the relationship between the birth weight and anthropometric measurements of newborn, maternal body habitus and glycemic control in GDM group. Methods : Maternal weight, height, and obstetric history of 82 women with GDM and 93 women with normal glucose tolerance were recorded at the... |
Purpose : The polymerase chain reaction(PCR) has been used for the early diagnosis of mycoplasmal infections using various clinical samples. In this study, the clinical utility of sputum PCR through a new method was studied to diagnose mycoplasma pneumonia. Methods : One hundred nineteen pneumonic patients, ages ranging from 15 months old to 15 years old, were examined from Aug, 1997... |
Purpose : During hematopoietic differentiation of HL-60 cells by DMSO and PMA, we demonstrated functional changes of HL-60 cells-phagocytic activity, respiratory burst, antibody-dependent cell-mediated cytotoxicity(ADCC) and opsonophagocytic activity. Methods : HL-60 cells(ATCC CCL-240), cultured in RPMI 1640 and supplemented with 10% FBS, were induced to differentiate by adding 1.0% DMSO or 16nM PMA. On the 4th and 7th day after... |
Purpose : The purpose of this study is to help diagnosis migraine and tension-type headache in children with chronic recurrent headache by comparing clinical characteristics of migraine and tension-type headache Methods : We performed a clinical analysis of 89 children diagnosed as migraine and/or tension- type headache by using international headache society classification with the aid of Prenky’s criteria of migraine... |
Purpose : It has been shown that a considerable number of acute myeloid leukemia(AML) patients had both myeloid and lymphoid antigens. CD7 is a lymphoid antigen, often expressed in AML cells. We investigated 40 AML patients to clarify the relationship between the cellular characteristics and clinical features. Methods : We reviewed 8 CD7 positive(CD7+) AML patients and 32 CD7 negative(CD7-)... |
Purpose : The survival rate of those with acute lymphoblastic leukemia(ALL) has been affected by several prognostic factors and previous reports show that a 4-year event-free survival(EFS) for high-risk(HR) group(Age≥10 years and/or WBC≥50,000/mm3 at diagnosis) was approximately 64%. We analyzed treatment outcomes and risk factors in HR-ALL. Methods : Medical records of 27 patients with HR-ALL diagnosed between May, 1985 and... |
Purpose : Postnatally, 20% of children with intrauterine growth retardation(IUGR) has no catch- up growth, This might be dependent on the serum level of Insulin-like growth factor I(IGF-I), resulting in shortness. We measured serum levels of IGF-I and Insulin-like growth factor binding protein-3(IGFBP-3) in children with IUGR and normal short stature variants(NSSV) to observe whether they play a role in... |
Purpose : Multiple allergosorbent test-chemiluminescent assay(MAST-CLA) is a semiquantitative method for detecting total IgE and specific IgE in serum. The purposes of this study are to investigate the correlation between MAST-CLA and Paper radioimmunosorbent test(PRIST), and to find out whether MAST-CLA can replace PRIST in measuring of serum total IgE. Methods : Data of 162 subjects were analyzed by linear... |
Purpose : Skin prick test and determination of allergen-specific IgE antibodies in serum are methods commonly used to diagnose allergies. Several studies indicate that skin test and specific IgE have roughly the same diagnostic precision, although discrepancies exist. The objective of this study was to evaluate the influence of total serum IgE on the relation between skin prick test and... |
MELAS(mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes) syndrome is a major subgroup of mitochondrial myopathy. Recent advances in molecular genetics revealed specific mutations in mitochondrial DNA which cause MELAS. We described here clinical and molecular genetic findings of sister and brother with MELAS syndrome. For molecular genetic studies, DNAs from peripheral blood nucleated cells were used. And the substitution... |
Oculocerebrorenal syndrome of Lowe(OCRL) is a rare X-linked disorder characterized by congenital cataract(oculo-), hypotonia, developmental delay, cognitive impairment(cerebro-), renal tubular dysfunction(renal), and growth retardation. Recently, the defective gene, OCRL-1 gene encoding [PtdIns(4,5)P2] 5-phosphatase, was cloned with mutations identified in patients. Although there have been about 200 cases of OCRL reported in English literature, only three reports have been published in... |
Thymic carcinoma is a malignant neoplasm arising from the thymic epithelium, and is known to be extremely uncommon in the pediatric population. The tumor is clinically highly aggressive with frequent local intrathoracic spread and extrathoracic metastases detected in the majority of patients at initial diagnosis and often shows minimal or no response to conventional chemotherapy. We experienced two pediatric patients... |
Paragonimiasis is a parasitic disease found in carnivorous animals which is caused by trematodes of the genus Paragonimus. Human infestation occurs by ingestion of raw or not incompletely cooked freshwater crab or crayfish with the metacercaria. Recently, the prevalence of human paragonimiasis has decreased markedly, however, about one hundred clinical cases have been diagnosed annually by antibody test in Korea.... |
Urea cycle disorders are characterized by encephalopathy, respiratory alkalosis, and hyperammonemia. A urea cycle disorder should be considered a diagnostic possibility in any patient regardless of age with occult encephalopathy. The most common central nervous system pathology of urea cycle disorder is cerebral edema. The cerebral edema is caused by astrocyte swelling secondary to hyperammonemia and intracellular glutamine accumulation. Strokes... |
For the immediate proper respiratory care of a delivered newborn, the face is wiped immediately, and the mouth and nares should be suctioned. A soft rubber syringe or soft rubber catheter is suitable for suctioning. If respirations are infrequent, suction of the mouth and pharynx serves to stimulate breathing. We experienced a case of a foreign body in the distal... |
