The administration of cytotoxic chemotherapy may be complicated by the emergence of neutropenia and febrile neutropenia, frequently determining hospital admission and intravenous treatment with broad spectrum antibiotics. Frequently, it is necessary to reduce the dose or to delay the administration of the cytotoxic drugs reducing the relative dose intensity of the chemotherapy regimen. Granulocyte growth factor...

Allogeneic stem cell transplantation in patients with myelodysplastic syndrome:...

We determined the outcome of patients with myelodysplastic syndrome (MDS) and secondary acute myeloid leukemia (sAML) after allogeneic stem cell transplantation according to their international prognostic scoring system (IPSS) risk categories at diagnosis. A total of 11 females and 7 males, with a median age of 45 years, were transplanted. With a median follow-up of 60 months, the 6-year actuarial event-free su...

Autologous stem cell transplantation in acute myeloid leukemia. Factors influen...

We report our results of autologous stem cell transplantation (SCT) in patients with AML during the last 13 years. Between August 1990 and December 2003, 42 patients with acute myeloid leukemia (AML) received an autologous SCT. Patients were classified as standard risk if first complete remission (CR) was induced after one or two chemotherapy regimens and the white blood cell count at presentation was below 50,...

Cardiovascular responses to microinjections of GABA or anesthetics into the ros...

The rostral ventrolateral medulla (RVLM) contains neurons involved in tonic and reflex control of arterial pressure. We describe the effects of gamma-aminobutyric acid (GABA) and anesthetics injected into the RVLM of conscious and urethane (1.2 g/kg, iv) anesthetized Wistar rats (300-350 g). In conscious rats, bilateral microinjection of GABA (50 nmol/200 nl) induced a small but significant decrease in blood pr...

Cúpulas Acetabulares em Próteses Totais da Anca Não Cimentadas (Dez Anos de Exp...

Os autores apresentam um estudo baseado na revisão clínica e radiográfica das artroplastias da anca não cimentadas, efectuadas no Serviço entre 1981 e 1991. Foram revistos 295 casos, em doentes com idades compreendidas entre os vinte e sete e os setenta e quatro anos, sendo a coxartrose a patologia que mais frequentemente levou à intervenção cirúrgica. Da análise realizada concluímos: 1 - As cúpulas em titânio ...

Bone marrow transplantation. Preliminary results.

From May 1989 to March 1991 60 bone marrow transplants were performed--41 allogeneic and 19 autologous--in patients with malignant and nonmalignant hemopathies and solid tumors. The transplant related mortality was 19.4% and 10.5% for allografts and autografts, respectively. The projected relapse free survival at 22 months in patients with malignant hemopathies who underwent allotransplantation in early phase w...

Donor leukocyte infusion after allogeneic stem cell transplantation.

Adoptive cellular immunotherapy with donor leukocytes of patients submitted to allogenic stem cell transplantation has had significant success in the past few years, especially in the treatment of primary disease relapse and in the prevention and treatment of some post-transplant infectious complications. Most patients treated with donor leukocytes had a relapse of chronic myelogenous leukemia, which was succes...

Aplastic anemia. Alternative treatment by bone marrow transplantation.

We report a case of a 25-year-old woman, with the diagnosis of severe aplastic anemia without a histocompatible sibling donor for bone marrow transplantation. The patient has been treated successfully with a combination of two immunosuppressive agents, cyclosporine and antilymphocyte globulin, after not responding to primary therapy with corticosteroids and growth factors. She showed a complete response to trea...

Methods for preserving bone marrow for autologous transplantation.

For Autologous Bone Marrow Transplantation (ABMT) the patient's own marrow is harvested before myelotoxic high-dose radio-chemotherapy and later returned to promote hemopoietic reconstitution. Between harvest and return the bone marrow must be preserved. The time elapsed between harvest and return depends on the intended therapy. Although--bone marrow may keep its hematopoietic potential for a few days without ...
