Seven children with chronic or intermittent and six with acute idiopathic thrombocytopenic purpura (ITP) were treated with large intravenous doses of polyvalent, intact immunoglobulin (Ig). In all patients the platelet count rose sharply within 5 days, but the initial response and the subsequent course varied from patient to patient. Among children with(More)
Microbeam radiation therapy (MRT), a form of experimental radiosurgery of tumours using multiple parallel, planar, micrometres-wide, synchrotron-generated X-ray beams ('microbeams'), can safely deliver radiation doses to contiguous normal animal tissues that are much higher than the maximum doses tolerated by the same normal tissues of animals or patients(More)
In a randomised, multicentre study intravenous IgG was compared with oral corticosteroids in 108 children with untreated acute immune thrombocytopenic purpura. IgG was an efficient treatment with no severe untoward reactions. The effects of corticosteroids and IgG were identical for rapid responders, who accounted for 62% of all patients. In contrast,(More)
BACKGROUND In childhood, cisplatin is an essential component of solid tumour therapy such as in neuroblastomas, germ cell tumours, bone tumours, liver tumours and brain tumours. The potential nephotoxicity of cisplatin is widely recognized, but little information is available on permanent sequelae. METHODS Of the 500 children included in the Swiss(More)
Malignant lymphocyte populations in peripheral blood of patients with B-cell chronic lymphocytic leukemia, leukemic variant of B-cell non-Hodgkin's lymphoma, and hairy cell leukemia can be characterized by the use of a monoclonal murine antibody (anti-Y 29/55) which is directed against a cell membrane component normally confined to the sessile(More)
285 Following leukaemogenic "trans-formation" the proliferation control is certainly affected-either directly (as is likely in the pluripotent stem cells), or indirectly (e.g. by interfering with the proliferation limiting maturation processes-the so-called " suicide maturation "-in the transit populations). Differentiation control is also affected on(More)
