| Bone marrow necrosis is a rare complication of a variety of diseases affecting the marrow. The cause and incidence are unknown, and reports of treatment response are rare. We describe a case of relapsed acute mixed type leukemia with bone marrow necrosis. The patient was a 10 year old female diagnosed with acute mixed type leukemia four years ago. She... |
| Lymphangiomatosis, a benign tumor consisting of a cluster of dilated lymphatic channels, is very unusual. Most lymphangiomatoses are found in the neck and head area. Less than 5% are diagnosed intraabdominally and they are very infrequently encountered in the retroperitoneal area. Herein, we report a rare case of asymptomatic lymphangiomatosis of a 13 year-old boy during a routine chest... |
| 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 : Bone involvement is known to develop in 40-70% of pediatric acute leukemia. We aimed to analyze the clinical course and result of therapy in pediatric acute leukemia with bone involvement. Methods : Twenty-seven patients diagnosed as pediatric acute leukemia at Dong San Medical Center from Jan. 1996 to Aug. 1998 were evaluated. According to bone X-ray and whole body... |

Methods : This study included 12 children with GHD. We measured IGF-I levels by RIA... |
| Purpose : Estrogen deficiency causes sexual infantilism in Turner syndrome, which could decrease the bone mineral density(BMD) since birth. This decreased BMD might be contributed by the decreased growth hormone(GH) secretion. To improve the decreased BMD, estrogen therapy is recommended, especially after the pubertal age, but estrogen therpay during childhood can accelerate the epiphyseal fusion, resulting in shorter final height. There is... |
| Purpose : Osteoporosis and growth failure have been known one of the serious side effects of corticosteroid therapy especially in children. This study was designed to evaluate the effect of long-term administration of steroids on bone mineral density(BMD) in children with nephrotic syndrome and its relationship to cumulative steroid dose, the duration of the rapy and sex. Methods : The BMD of... |
| Diffuse myalgia is common in transient systemic viral infections but overt myositis, with weakness and signs of muscle inflammation, rarely accompanies viral infection in chidren. We describe a 8-year-old boy with severe myalgia and tenderness in both lower extremities, whose unusual skeletal muscle uptake on Technetium-methylene diphosphate bone scan helped to diagnosis of myositis. Clinical course, muscle-derived enzyme studies(AST, ALT,... |
| Bone mineral densitometry is a useful procedure for the early detection of metabolic bone diseases and bone density changes caused by long term drug use. Dual energy X-ray absorpt- iometry(DEXA), a recently developed diagnostic radiologic method for evaluating bone mineral density is widely used because of its high sensitivity, easily obtaine results. and low dose radi- ation exposure. The study... |

Fifteen children, comprising 10 male and 5 female, dignosed with convulsive disorders and administered with phenobarbital for a long term period of more than 9 months but less than 84 months and 15 healthy children... |
| We performed this study to evaluate the therapeutic responses of bone marrow transplantation and immunosuppressive therapy for aplastic anemia in 103 cases(68 severe and 35 moderate). Among them, 15 cases with severe aplastic anemia having HLA-identical sibling donor underwent bone marrow transplantation, and cases (53 severe and 35 moderate cases) without available HLA-identical sibling donor had received immunosuppressive therapy using... |
| Medulloblastoma and primitive neuroectodermal tumor(PNET) are relatively common intracranial neoplasms in childhood. Their extracranial metastasis were thought to be rare occurrences. But they are more frequent compared to other intracranial tumors. The most frequent site of metastasis deposits in medulloblastoma is bone, and metastasis to lymph node, peritoneum, liver or lung have been reported infrequently. The authors experienced three cases... |
| NHL is a malignant tumor that invade in abdominal cavity, mediastinum, cervical lymph node, rarely in peripheral lymph node, skin, and bone. Primary malignant lymphoma of bone with multiple punched-out lesion on simple radiologic examination was not reproted yet. We experienced a case of primary NHL of bone with multiple punched-out lesion on simple radiologic examination, in a 3-year 7-month old boy... |
| Bone marrow necrosis is a rare complication most commonly encountered in patients with leuke- mia, metastatic tumor in marrow, sickle cell disease, DIC and severe infections. Recently it is regarded as a more common finding frequently overlooked and carrying not so poor prognosis. We reported here a boy with ALL who showed marrow necrosis on biopsy at the time of diagnosis and achieved complete... |
| Twenty, six children younger than 15 years with severe aplastic anemia underwent either bone marrow transplantation or immunomodulation therapy (antilymphocyte globulin with cyclosporin A therapy). Six patients who had an HLA-identical sibling donor underwent bone marrow transplantation after conditioning with cyclophosphamide, procarbazine and antilymphocyte globulin. Twenty children who did not have an HLA-identical donor recieved antilymphocyte globulin and cyclosporin A. The results were as follows; 1) Hematologic responses:... |
