BACKGROUND Infantile Krabbe's disease produces progressive neurologic deterioration and death in early childhood. We hypothesized that transplantation of umbilical-cord blood from unrelated donors before the development of symptoms would favorably alter the natural history of the disease among newborns in whom the disease was diagnosed because of a family(More)
OBJECTIVE To determine the incidence of pressure ulcers in varied populations, and whether demographic characteristics (age, gender, race) and primary diagnosis are factors in pressure ulcer development when the level of risk for developing ulcers is considered. To determine if there is a difference in the type of preventive services prescribed for persons(More)
BACKGROUND Although the frequency of complications in adults undergoing therapeutic apheresis is low, there are little data in children. STUDY DESIGN AND METHODS A retrospective study of 186 children who had undergone a total of 1632 apheresis procedures between 1994 and 2002 was conducted. Adverse reactions were prospectively documented. The procedures(More)
The purpose of this study was to determine dose-limiting toxicities and pharmacokinetics of imatinib in children with refractory or recurrent Philadelphia chromosome-positive (Ph(+)) leukemias. Oral imatinib was administered daily at dose levels ranging from 260 to 570 mg/m(2). Plasma pharmacokinetic studies were performed on days 1 and 8 of course 1. There(More)
BACKGROUND Renal-cell carcinoma (RCC) is a rare tumor in children. To address whether RCC in children differs from its adult counterpart, we report a series of 16 children with RCC (5 boys, 11 girls, mean age 9.6 years, range 3-19 years) presenting between 1979 and 1996 at three pediatric centers. PROCEDURE Pathology showed papillary RCC in five patients(More)
SUMMARY High-dose busulfan is an important component of myeloablative regimens. Variable drug exposure may occur following oral administration. Therefore, the use of intravenous busulfan has been advocated. Previous work has suggested a cumulative dosage of 16 mg/kg for haematopoietic transplantation in children less than 3 years of age, but only limited(More)
Seventeen patients transplanted with hematopoietic cells to correct severe T lymphocyte immunodeficiency resulting from complete DiGeorge anomaly were identified worldwide, and retrospective data were obtained using a questionnaire-based survey. Patients were treated at a median age of 5 months (range, 2-53 months) between 1995 and 2006. Bone marrow was(More)
Recent evidence indicates that bone-marrow-derived stromal cells (MSCs) have a histology coherent with endothelial cells that may enable them to contribute to tumor angiogenesis through yet undefined mechanisms. In this work, we investigated the angiogenic properties of murine MSCs involved in extracellular matrix degradation and in neovascularization that(More)
A case of acute myelocytic leukemia (AML) M5 subtype (French-American-British classification), in a 13-year-old girl showed the abnormal karyotype 46,XX,t(11;17)(q23;q21) in all bone marrow cells analyzed. Rearrangements involving 11q23 are frequent in cases of AML M5 and often involve the MLL gene. Nevertheless, t(11;17)(q23;q21) is very rare in this type(More)
Busulfan (BU) is a key compound in conditioning myeloablative regimens for children undergoing hematopoietic stem cell transplantation (HSCT). There are wide interindividual differences in BU pharmacokinetics, which increase the risk of veno-occlusive disease, graft rejection and disease relapse. As BU is mainly metabolized by glutathione S-transferase(More)
