Early, low-risk International Prognostic Scoring System (IPSS) myelodysplastic syndrome (MDS) is a heterogeneous disorder where the molecular and cellular hematopoietic defects are poorly understood. To gain insight into this condition, we analyzed gene expression profiles of marrow CD34+ progenitor cells from normal-karyotype, low-blast-count MDS patients,(More)
Chronic lymphocytic leukaemia (CLL) is a B-cell disorder, which has a median survival of over 10 years from diagnosis for stage A disease. The natural history of stage A disease is generally indolent or only slowly progressive. It is less well known that CLL may undergo spontaneous regression. We report a series of 10 such cases (eight stage A and two stage(More)
Intermittent painful crises due to vasoocclusion are the major clinical manifestation of sickle cell disease (SCD), but subclinical episodes may also occur. There is sparse evidence for the involvement of neutrophils in the pathophysiology of SCD, but production of cytokines by the damaged endothelium might influence neutrophil function and modulate(More)
The authors present a case where the simultaneous administration of 6-mercaptopurine (6-MP) and cow's milk during maintenance treatment for acute lymphoblastic leukemia led to elevated full blood counts resistant to increasing doses of chemotherapy. The blood counts returned to the expected range after milk intake with chemotherapy was discontinued.
The insertion of Hickman central venous catheters for chronic venous access is a procedure usually conducted in the operating theatre under local or general anaesthesia. In a prospective study over a one year period we have assessed the feasibility of radiologists inserting central venous catheters for long term access. A subclavicular approach to the(More)
Neutropenia induced by antiviral treatment, in particular AZT, can be improved with recombinant human granulocyte macrophage colony stimulating factor (RHGMCSF) in HIV positive patients. However, there has been concern that this may increase the HIV load in the mononuclear cells of such patients. Five patients receiving AZT plus low dose RHGMCSF are(More)
Peripheral blood cytopenias present a major problem in the management of patients with HIV infection. Their pathophysiology is likely to be multifactorial, although there is controversy as to whether haemopoietic progenitors are a target for HIV. In order to investigate the haemopoietic defect in HIV infection, we looked at bone marrow culture(More)
PURPOSE To identify factors that determine patients' intentions to use point-of-care medical devices, ie, portable coagulometer devices for self-testing of the international normalized ratio (INR) required for ongoing monitoring of blood-coagulation intensity among patients on long-term oral anticoagulation therapy with vitamin K antagonists, eg, warfarin.(More)
