Purpose : Mycoplasma pneumoniae is a common cause of lower respiratory disease, especially in children and young adults. The diagnosis, in most cases, is confirmed by serology. M. pneumoniae is difficult to culture because of its fastidious nature, and growth is too slow for diagnostic use. In this prospective study, the sensitivity and specificity of the PCR assay was evaluated... |
Acute focal bacterial nephritis(AFBN) is an unusual form of localized renal infection, which has various imaging findings and should be distinguished from abscess or other renal masses. Clinical symptoms are similar to other urinary tract infections but the diagnosis needs a CT or sonographic confirmation. Treatment, which is nonoperative, consists of intensive antibiotic therapy. We report three cases of AFBN... |

Purpose : Respiratory distress syndrome(RDS) is a major cause of death in premature babies. For the treatment of RDS, various artificial pulmonary surfactants have been used. The incidence of pulmonary hemorrhage is increased in association with surfactant therapy in extremely low birth weight infants. But the pathogenesis of this increased incidence is not clear. So we conducted this study... |
Congenital factor Ⅶ deficiency is a rare bleeding disorder with an estimated incidence of 1 in 500,000. It is inherited as an autosomal recessive pattern with variable expression and high penetrance. In severely affected patients, repeated hemarthroses, chronic crippling hemarthropathy, and dangerous hematomas can occur. Other types of hemorrhage include epistaxis, menorrhagia, hematuria, gastrointestinal and gingival bleeding. Fetal cerebral hemorrhage... |
Crouzon syndrome, an autosomal dominant disorder, has characteristic features of craniosynostosis, hypertelorism, exophthalmos, maxillary hypoplasia and relative mandibular prognathism. Mutations of fibroblast growth factor receptor 2(FGFR2) gene are associated with craniosynostotic conditions, such as Crouzon syndrome, Jackson-Weiss syndrome, Pfeiffer syndrome, Apert syndrome and Beare-Stevenson cutis gyrata. We found one child with common morphological features of Crouzon syndrome. Interestingly, she... |

Purpose : Low-dose dopamine(0.5-3μg/kg/min) increases renal blood flow, glomerular filtration rate and natriuresis and has protective and therapeutic effects on oliguric renal failures. Asphyxia is the most common cause of acute renal failure in neonates. But the protective effects of dopamine have never been reported in asphyxiated neonates. So we reported the effects of low-dose dopamine on the renal function... |

The complications of childhood obesity are depression, adult obesity, hypertension, diabetes, hyperlipidemia, coronary artery disease and fatty liver. Therefore, accurate diagnosis of obesity is important. The purpose of this study was to assess diagnostic sensitivity to predict hypelipidemia by bioelectrical impedance analysis(BI) in obese children. Methods : One hundred fifteen healthy... |
Purpose : Despite improved surgical techniques, pulmonary regurgitation is a common postoperative sequelae in patients with tetralogy of Fallot. Pulmonary regurgitation may induce deterioration of right ventricular performance, right ventricular dilatation and ventricular arrhythmia. The evaluation of the clinical significance of pulmonary regurgitation in postoperative tetralogy of Fallot has been troublesome since there was no technique that could accurately quantitate... |

Results : There are no significant difference in total leukocyte count, immature to mature rentrophil ratio, toxic granules, and... |
Purpose : Insulin-like growth factors(IGFs) are mitogenic peptides that are essential for fetal and maternal tissue growth during pregnancy. They circulate primarily with serum IGF-binding protein(IGFBP) which regulates the availability of IGFs to their specific target tissue. This study was performed to examine the relationships between birth weight and IGFs, insulin and growth hormone in the sera of cord blood... |
Ectopic pancreas is defined as pancreatic tissue lacking anatomical and vascular continuity with the main body of the pancreas. Common symptoms are epigastric pain, hemorrhage, chest pain, weight loss, nausea and vomiting. A 2-month-old male patient was hospitalized because of continuous bile stained vomiting for 2 days. Abdominal ultrasonography and colon study showed malrotation of the intestine. Surgical exploration revealed... |
Pulmonary artery sling is a rare and potentially lethal vascular anomaly wherein the anomalous left pulmonary artery arises from the posterior aspect of the right pulmonary artery and passing to the left lung between the trachea and the esophagus which causes respiratory distress in infants and children due to the extrinsic compression of the airway by the anomalous vessel. Associated... |
Purpose : One of the new methods for diagnosing congenital cardiovascular diseases is the spiral CT and three-dimensional image reconstruction. The spiral CT allows continuous data collection while the subject is advanced through the CT gantry, it provides an uninterrupted volume of data that can be reconstructed to produce a three-dimensional representation of CT information and also this method has... |

Methods : Thirth-two Mechanically ventilated pretem infants(gestational age<34... |
Intestinal lymphangiectasia is a primary or secondary disorder of lymphatics which is associated with protein-losing enteropathy, hypoalbuminemia, edema, abdominal distension and growth failure. The patients with this disease lose albumin, immunoglobulins, and lymphocytes through the bowel. We have experienced one case of intestinal lymphangiectasia in 8 month-old boy, whose chief complaint was abdominal distension and watery diarrhea. He had hypoalbuminemia(1.7gm/dl).... |
Nutcracker esophagus and hypertensive lower esophageal sphincter(LES) are primary esophageal motility disorders. Nutcracker esophagus have demonstrated distal esophageal contraction amplitude that exceeds the normal range(>160mmHg), without association abnormalities of the esophageal contraction wave, or lower esophageal sphinter relaxation. The criteria for diagnosing hypertensive LES take the mean LES pressure >45mmHg, LES relaxation >75% and normal peristalsis, which is a poorly... |
