Severe aplastic anemia (SAA), a fatal disease, requires multiple transfusion, immunosuppressive therapy, and finally, hematopoietic stem cell transplantation (HSCT) as the definitive treatment. We hypothesized that iron overloading associated with multiple transfusions and HSCTrelated complications may adversely affect cardiac function. Left ventricular (LV) function was assessed in children after HSCT for SAA. Forty-six consecutive patients with a median age of 9.8... |
Varicella-zoster virus infection can lead to severe illness in immunocompromised patients. Further the mortality rate of disseminated varicella infection is extremely high particularly in immunocompromised children. We report a case of disseminated varicella infection in a child with acute lymphoblastic leukemia who was receiving chemotherapy, but was initially admitted with only for acute abdominal pain. The patient rapidly developed severe... |
Purpose : This study aimed to determine the frequencies of CD4+CD25+ T cells in donor graft and peripheral blood CD4+CD25+ T cells in recipients after hematopoietic stem cell transplantation (HSCT) and their association with graft-versus-host disease (GVHD). Methods : Seventeen children who underwent HSCT were investigated. CD4+CD25+ T cells in samples from donor grafts and recipient peripheral blood were assessed... |
Purpose : In this study, we retrospectively analyzed the clinical outcomes of patients who underwent allogeneic hematopoietic stem cell transplantation (HSCT) grafted from HLA-matched parents. Methods : Seven children with acute leukemia (4 acute lymphoblastic leukemia, 3 acute myeloid leukemia) in first complete remission received allogeneic HSCT from their respective parents at the St. Marys Hospital between April, 1999 and October,... |
Purpose : Due to its high potency against leukemic blasts, our institution has opted for the use of dexamethasone during acute lymphoblastic leukemia (ALL) remission induction, but in our most recent treatment protocol, CMCPL-2005, we shortened the length of steroid treatment from 4 to 3 weeks. We compared both the rates of remission induction and significant complications observed during induction... |
Aplastic anemia is a rare disease, which is characterized by pancytopenia and hypocellular bone marrow without infiltration of abnormal cells or fibrosis. The incidence in Asia is higher than in the West and new cases are diagnosed at a rate of 5.1 per million pediatric populations per year in Korea. The pathophysiology is understood roughly by defective hematopoiesis, impaired bone... |
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 :... |
Purpose : We reviewed 100 cases of HLA-matched sibling allogeneic bone marrow transplantation( allo-BMT) in children and wish to share these results. Methods : One hundred children had undergone allo-BMT from HLA-identical siblings between Nov. 1983 and May 1998. There were 50 males and 50 females with a median age of 10 years and a median follow-up of 38 months. Out of 100 cases,... |
Between 1986 and 1990, four children with recurrent CNS leukemia who had previous NS prophylaxis therapy were treated with intermittent central nervous system irradiation and intrathecal chemotherapy (IIC). There was no isolated CNS recurrence. One patient died from bone marrow relapse. Three patients are alive without evidence of disease for 33/12 year to 36/12 years after the diagnosis of recurrence... |
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... |
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:... |
Immunoglobulin (Ig) and T cell receptor 0 chain (TcR分) gene rearrangements can be used as ”genetic marker” of lineage and clonality in the study of lymphoproliferative disease. We analyzed genomic DNA of the bone marrow mononuclear cells from twenty six patients with acute leukemia in children. The patients were seventeen cases of acute lymphocytic leukmia (ALL), seven cases of acute nonlymphocytic leukemia (ANL) and... |
The hybrid acute leukemia is defined as acute leukemia with both myeloid and lymphoid features. We experienced and report two cases of hybrid leukemia which were identified by morpholgy, cytochemical stain, reactivity with monoclonal antibody, analysis of immunoglobulin and T cell receptor genes rearrangement in 14 years old boy and 10 years old girl. |
Thirty patients with aplastic anemia(fifteen severe aplastic anemia and fifteen moderate aplastic anemia) treated with antilymphocyte globulin and cyclosporin A as a kind of immunomodulation therapy were studied by analysing hematologic reseponses and complications. The results were as follows; 1) Nineteen out of thirty patients (63.3%) treated with anti lymphocyte globulin plus cyclosporin A showed responses (complete response of 33.3%, partial response of 30.0%). 2) Hematologic responses according... |
We observed the patients admitted to the department of pediatrics of St. Mary*s Hospital, Catholic Medical College during the past 20 years from Jan. 1966 to Dec. 1985 and classified them by year and disease according to the International Classification of Disease by W.H.O. (1965 Revision). The results were as follows: 1) The total number of pediatric inpatients during 20 years was 18,686, of which... |
Most chondroma often occur within or on the surface of the tubular bone and soft tissue, and are also found in many organs, but it is extremely rare in the mediastinum. Recently, we experienced a case of chondroma of the middle mediastinum, in a 13-years old girl with intermittent chest discomfort and exertional dyspnea for several months. Diagnosis was made by... |
Pateat urachus is a uncommon disease and it has a good prognosis if there is no combired major anomaly and evidence of malignancy. This paper presents one case of patent urachus which was found and removed surgically during the neonatal period. A brief review of related literatures is also presented. |
