Seconnday aneurysmal bone cyst is the disease that occurrs in the primary bone tumor and/or tumorus conditions Meticulous search is needed to make a correct diagnosis which dose not overlook the primary diseases. We have experinced an osteolytic lesion on the 7-year-old boy on his skull bone. Plain radiography of the skull revealed osteolytic lesion in the parieto-occipital bone. On... |
Purpose : Neutrophils are central to the defences against bacterial infection, and in neonates the number of neutrophils are decreased due to inhibited production and phagocytic function. This induces high mortality rates in infants suffering from neonatal sepsis. Exogenous GM-CSF can increase the number of neutrophils and improve the phagocytic function. To establish the most cost effective dose of exogenous... |

Methods : A study was performed in 36 children with prenatal diagnosis of MCDK from 1989 to 1999. All... |
Megacystis Microcolon Intestinal Hypoperistalsis(MMIH) Syndrome is a rare cause of functional neonatal bowel obstruction, characterized by hypoperistalsis, narrow distal ileum and colon, and bladder distension. We report a case of MMIH syndrome and review the literature. The patient was born after 34 weeks of gestation with marked abdominal distension. Her birth weight was 2,830g with 276ml of urine drained by... |
Cystic lymphangiomas are comparatively rare, benign tumors of lymphatic system and their histogenesis are uncertain. About 75% of theses lesions are in the neck, 20% are in the axillary region, and 5% are in the mediastinum, retroperitoneal region or groin. But retroperitoneal cysticlymphangiomas are very rare. Retroperitoneal cystic lymphangiomas are usually found incidentally during diagnostic procedures performed for unrelated clinical... |
Purpose : We studied smooth muscle strips from rabbit gastric antrum and low esophageal sphincter(LES) to explore the difference between newborn and adult rabbit on erythromycin(EM)- induced contractions. Another aim of this study was to determine the mechanism of LES contractile activities induced by erythromycin(EM). Methods : Muscle strips prepared from newborn and adult rabbits were stimulated with agonists such as KCl, motilin and EM,... |
Purpose : Postinfectious acute glomerulonephritis usually needs no renal biopsy. But atypical clinical course and laboratory results indicate a need for renal biopsy.

Methods : We conducted a retrospective study of 152 infants, 28 days or less of age, whose rectal temperature was at least 38℃. Past history, family history, finding on physical examinations and results of CBC,... |
The most clearly delineated condition with prominent cutaneous leukocytoclastic vasculitis which presents to a pediatrician is Henoch-Schönlein purpura. There is general agreement that in Henoch-Schönlein syndrome the skin manifestations have a very benign long-term course and that corticosteroids are of little value. Dapsone appears to be of special value in diseases characterized by an accumulation of polymorphonuclear neutrophils notably leukocytoclastic... |
Primary intestinal lymphangiectasia is a rare congenital disorder characterized by diffuse or localized ectasia of the enteric lymphatics, often in association with lymphatic abnormalities elsewhere in the body. The pathogenesis of these abnormal lymphatic structures is uncertain. Ectatic lymphatics may be located in the mucosa, submucosa, or subserosa, leading to a loss of protein and lymphocytes into the gut or... |

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 : 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-)... |
Allergic bronchopulmonary aspergillosis(ABPA) is an inflammatory disease which causes a hypersensitivity to Aspergillus spores growing in the bronchi. The clinical syndrome is characterized by asthma, recurrent pulmonary infiltrations or mucoid impaction, eosinophilia, and central bronchiectasis. A 12-year-old boy was admitted to our hospital because of right lower chest pain and cystic mass-like shadows on a chest X-ray film. He had... |
Individuals with Down syndrome have a high incidence of hematologic diseases such as transient myeloproliferative disorder(TMD) & acute leukemia. Because it is difficult to distinguish TMD from acute myeloblastic leukemia, the diagnosis in neonate, who have Down syndrome, should be made with extreme caution. TMD usually undergoes spontaneous remission within a few months, but acute leukemia can develope after remission... |
Purpose : A study was undertaken to assess the social background of abandoning children at adoption institutions. The results were compared to those of three previous reports from the institution.

Purpose : Williams syndrome is characterized by supravalvular aortic stenosis, mental retardation and peculiar facial appearance. Its genetic etiology is considered to be a hemizygotic deletion in Chromosome 7q11.23, which includes the elastin gene. We examined the hemizygotic deletion of Chromosome 7q11.23 in 12 Korean Williams syndrome patients and 8 patients with isolated supravalvular aortic stenosis and performed deletion mapping... |

Inappropriate secretion of antidiuretic hormone(ADH) secondary to vincristine therapy has been reported frequently. But there has been five previous reports of vinblastine associated SIADH in the world and in 4 reports, bleomycin and cis-platinum were used along with vinblastine together. Because penetration of vinka alkaloids into CSF of humans is known to be poor, it has been suggested that lowering... |
Congenital self-healing reticulohistiocytosis(CSHR) is a rare variant of cutaneous reticulohistiocytosis. We report a newborn who had about 25 reddish brown papulonodular lesions on whole body at birth. No extracutaneous involvement was found. All skin lesions involuted within 4 months spontaneously. Biopsy of a skin lesion showed marked aggregated histiocytic infiltration with some eosinophils. S-100 protein and lysozyme were positive. Electron... |
