| A twenty six months-old boy developed hemophagocytic syndrome during the course of Kawasaki disease. Despite the appropriate treatment modalities for Kawasaki disease, he developed thrombocytopenia, hepatomegaly, high-grade fever, hypertriglyceridemia, peripheral gangrene, and evidence of hemophagocytosis in bone marrow biopsy. Although the course was stormy, he responded well to a combination therapy of corticosteroid and etoposide. |
| Rett syndrome is an X-linked dominant, progressive neurodevelopmental disorder, with a prevalence estimated to be one in 10,000-15,000 girls, which is thought to be the second most common genetic causes of mental retardation in females after Down syndrome. Patients with classic Rett syndrome show an apparently normal neonatal period, followed by developmental regression and deceleration of head growth, accompanied by... |
| Gitelman's syndrome is an autosomal recessive disorder characterized by hypokalemic metabolic alkalosis, hypomagnesemia, and hypocalciuria that has recently been reported to be linked to thiazide-sensitive Na-Cl cotransporter gene mutation. In this study, we performed renal clearance studies to differentiate Gitelman's from Bartter's syndrome and to confirm the diagnosis in two patients clinically diagnosed with Gitelman's syndrome. Each patient was hydrated... |
| We experienced a case of partial DiGeorge syndrome in a 35+5 week premature female infant presented with micrognathia, fish-shaped mouth, beaked nose, nasal regurgitation, obstructive sleep apnea, velopharyngeal insufficiency and late onset hypocalcemic seizures. The chromosome 22q11 microdeletion was found by the FISH method. The lab findings showed serum calcium level of 4.4 mg/dL, ionized calcium level of 0.49 mg/dL,... |
| Purpose : In most cases, myelodysplastic syndrome(MDS) transforms into a more aggressive state or acute myelogenous leukemia; it's prognosis is very poor. It is believed that hematopoietic stem cell transplantation(HSCT) is the only curative treatment of MDS, but available data in children are very sparse. In this report, the short term outcome of HSCT in childhood MDS was analyzed. Methods :... |
| Typical hypoplastic left heart syndrome(HLHS) is a distinct pathologic entity with aortic atresia, mitral atresia, very hypoplastic or absent left ventricle and thread like ascending aorta. Occasionally, the lesser degree of hypoplasia is found and is called hypoplastic left heart complex(HLHC) by some authors. This HLHC is often associated with critical aortic stenosis. Fetal echocardiography has enabled us to observe... |
| Purpose : It is not clear that the development of glomerular injury and aggravation by tumor necrosis factor alpha(TNF-α) is related to intrarenal or serum concentration of TNF-α. So, we studied the relationship between the concentration of TNF-α and aggravation of glomerular damage in the Henoch-Schönlein nephritis(HSN) and idiopathic nephrotic syndrome(INS). Methods : We collected the sera and urines of... |
| Purpose : The development of external genitalia in genetic male is dependent on the transcriptional regulatory activity of dihydrotestosterone(DHT)-androgen receptor complex in the genital skin. The abnormality of androgen receptor encompasses a wide range of phenotypes. We investigated the androgen receptor binding capacity of genetic males with ambiguous genitalia(grade was determined by Prader grade) for the availability as screening test. Methods : The binding capacity... |
| Hyper-IgE syndrome is a rare congenital immune deficiency disease characterized by severe eczema, recurrent infection of the sinopulmonary tract, cold subcutaneous abscess and high serum IgE levels. It is an autosomal dominant disease with incomplete penetrance. We examined the case of a 12 month old infant with hyperIgE syndrome since neonate. The diagnosis of hyper IgE syndrome was made because... |
| Fanconi-Bickel syndrome is a rare autosomal recessive disorder of the carbohydrate metabolism recently demonstrated to be caused by mutations in GLUT2, the gene for the glucose transporter protein 2 expressed in the liver, pancreatic β islet-cells, intestine and kidney.

The first infant developed proteinuria at age 3 days. This condition appeared similar to that described by Galloway and Mowat and reviewed by Cooperstone, et al, especially the presence of abnormal gyral patterns. She died at 19 months. The second infant; the brother... |
| Trisomy 9 mosaicism is a disease characterized not only by intrauterine growth retardation and mental retardation but also congenital heart defects, musculoskeletal, genitourinary and CNS anomalies, as well as craniofacial anomalies such as microcephaly, micrognathia, narrowed temples, prominent occiput, broad-based nose with bulbous tip, low set ears, deeply set eyes, short palpebral fissure and small mouth. This syndrome was first reported back in 1973... |
| Vascular leak syndrome(VLS) is characterized by endothelial damage, which causes extravasation of plasma proteins and fluid from capillaries into the extravascular space. It has been suggested that the increased vascular permeability is the result of an IL-2-induced suppression of endothelin- 1 secretion by endothelial cells, an IL-2-induced activation of the complement cascade or TNF-αrelease from IL-2-activated T-cells. A 13-year-old male patient visited our hospital... |
| Apert's syndrome(acrocephalosyndactyly) is a rare congenital anomaly that is characterized by the combination of premature fusion of multiple cranial sutures primarily involving the coronal suture and severe symmetrical syndactyly of fingers and toes. Some patients of this syndrome have various abnormalities of the central nervous system. We experienced a case of Apert's syndrome with craniofacial malformations, symmetric syndactyly, occipital encephalocele... |

| The 49, XXXXY Klinefelter variant is distinctive; classic findings include mental retardation, hypogonadism and radioulnar synostosis. Its incidence is estimated to be 1/80,000 to 1/100,000 male births. We report a case of 49, XXXXY syndrome confirmed by chromosomal study in neonatal period, whose clinical features included a coarse face, short neck, micropenis, and other multiple minor anomalies including simian creases.... |
| We describe below a case of Zellweger syndrome case with facial dysmorphism, profound hypotonia, and hepatomegaly. He died at the age of 2 months. Zellweger syndrome is a disease marked by the absence of hepatic and renal peroxisomes. Because peroxisomes have many vital anabolic and catabolic functions within the cell, their absence results in profound cellular dysfunction. A biochemical study... |
| Klippel-Feil syndrome(KFS) consists of short neck, low posterior hairline and restriction of motion of the neck due to fusion of cervical vertebrae. The typical disorder results from a failure of the normal segmentation of mesodermal somites during 3-8 weeks of gestation. In 1912, the first complete clinical description of this syndrome was given by Klippel and Feil. Feil reported ... |
| Five to fifteen percent of patients affected by human immunodeficiency virus(HIV) are children in developing countries. In Korea, most of HIV infections in children have been transfusion-related, and cases of vertical transmission have been very rare so far and are usually suspected due to a maternal positive history. We experienced a case of vertical transmission of HIV in a 19... |
| Maple syrup urine disease(MSUD) is an autosomal recessive disorder involving the metabolism of the branched-chain amino acids(BCAA) such as leucine, isoleucine and valine. The disorder is due to a defect in branched-chain α-ketoacid dehydrogenase(BCKAD) and the classic form causes rapid progressive and overwhelming illness beginning in the first weeks of life, present with poor feeding, lethargy, change in muscle tone,... |
