Analysis of the interventions in antineoplastic therapy by a clinical pharmacy service at a tertiary hospital in Brazil.

Background: Medication errors are avoidable occurrences that can assume clinically significant dimensions and impose relevant costs to the health system, especially in the context of antineoplastic therapy.

Objective: Assess the clinical significance and economic impacts of a clinical pharmaceutical service. This retrospective study consists of an analysis of pharmacy interventions and drug-related problems found in a review of electronic prescriptions referring to antineoplastic therapy of a public teaching tertiary hospital in Brazil.

Autologous transplantation of bone marrow adult stem cells for the treatment of idiopathic dilated cardiomyopathy.

Background: Morbimortality in patients with dilated idiopathic cardiomyopathy is high, even under optimal medical treatment. Autologous infusion of bone marrow adult stem cells has shown promising preliminary results in these patients.

Objective: Determine the effectiveness of autologous transplantation of bone marrow adult stem cells on systolic and diastolic left ventricular function, and on the degree of mitral regurgitation in patients with dilated idiopathic cardiomyopathy in functional classes NYHA II and III.

Early lymphocyte recovery as a predictor of outcome, including relapse, after hematopoietic stem cell transplantation.

Background: Despite advances in the treatment of acute leukemia, many patients need to undergo hematopoietic stem cell transplantation. Recent studies show that early lymphocyte recovery may be a predictor of relapse and survival in these patients.

Objective: To analyze the influence of lymphocyte recovery on Days +30 and +100 post-transplant on the occurrence of relapse and survival.

Neurological complications of hematopoietic stem cell transplantation (HSCT): a retrospective study in a HSCT center in Brazil.

We present the neurological complications evaluated in a series of 1000 patients who underwent hematopoietic stem cell transplantation (HSCT). Central nervous system (CNS) neurological complications, particularly brain hemorrhages, were the most common, followed by seizures and CNS infections. An unusual neurological complication was Wernicke's encephalopathy.

[Prevalence of hemoglobin S in the State of Paraná, Brazil, based on neonatal screening].

The Brazilian Ministry of Health created the National Neonatal Screening Program under ruling no. 822/2001, including neonatal screening for hemoglobinopathies. In the State of Paraná, neonatal screening is conducted by the Ecumenical Foundation for the Protection of the Handicapped.

HLA-matched related donor hematopoietic cell transplantation in 43 patients with Fanconi anemia conditioned with 60 mg/kg of cyclophosphamide.

Cells from Fanconi anemia (FA) patients are hypersensitive to alkylating agents and radiation traditionally used as conditioning regimens for marrow cell transplantation, and patients experience serious toxicities. To reduce toxicities, we used progressively lower doses of cyclophosphamide (CY) for conditioning. Here, we report the results in 43 FA patients who received marrow transplantation from HLA-matched related donors (37 siblings and 6 other relatives).

Allogeneic hematopoietic stem cell transplantation from an alternative stem cell source in Fanconi anemia patients: analysis of 47 patients from a single institution.

We transplanted 47 patients with Fanconi anemia using an alternative source of hematopoietic cells. The patients were assigned to the following groups: group 1, unrelated bone marrow (N = 15); group 2, unrelated cord blood (N = 17), and group 3, related non-sibling bone marrow (N = 15). Twenty-four patients (51%) had complete engraftment, which was not influenced by gender (P = 0.

Bone marrow transplantation in patients with storage diseases: a developing country experience.

Bone marrow transplantation (BMT) is a therapeutic option for patients with genetic storage diseases. Between 1979 and 2002, eight patients, four females and four males (1 to 13 years old) were submitted to this procedure in our center. Six patients had mucopolysaccharidosis (MPS I in 3; MPS III in one and MPS VI in 2), one had adrenoleukodystrophy (ALD) and one had Gaucher disease.

Low-dose cyclophosphamide conditioning for haematopoietic cell transplantation from HLA-matched related donors in patients with Fanconi anaemia.

Allogeneic haematopoietic cell transplantation (HCT) is effective therapy for Fanconi anaemia (FA). FA patients do not tolerate conditioning with 200 mg/kg of cyclophosphamide (Cy), typically used in aplastic anaemia. We previously published results of studies in which Cy doses were gradually reduced from 200 to 100 mg/kg.

Fibroelastoma of the mitral valve as a cause of transient ischemic stroke.

A 44-year-old woman had a transient ischemic stroke, fibroelastoma of the mitral valve being the source of the embolus. The patient evolved with neutropenia induced by ticlopidine after 10 days of treatment. We report the major clinical features, therapeutical options, and medicamentous toxicity resulting from the use of antiplatelet drugs.

Long-term outcome of 25 children and adolescents with severe aplastic anemia treated with antithymocyte globulin.

Severe aplastic anemia (SAA) is probably an immune-mediated disorder, and immunosuppressive therapy is recommended for patients with no available donor for bone marrow transplant. Between October 1984 and November 1987, 25 consecutive children and adolescents with SAA with no HLA-compatible marrow donor received equine antithymocyte globulin (ATG) (15 mg kg-1 day-1) for 10 days. The patients were evaluated 6 weeks, 6 months, and 12 months after starting ATG treatment.

Bone marrow transplantation for patients with Fanconi anemia: reduced doses of cyclophosphamide without irradiation as conditioning.

Fanconi anemia (FA), a rare autosomal recessive disease, frequently evolves to bone marrow failure and acute myeloid leukemia, and BMT is the treatment of choice for patients with FA. However, their exquisite hypersensitivity to DNA cross-linking agents is associated with severe complications and several investigators have been looking for the ideal preparatory regimen. We have been involved in a program of progressively decreasing doses of cyclophosphamide (CY) as conditioning therapy, in an attempt to identify the lowest dose of CY capable of maintaining the graft with minimum complications.

Iatrogenic Wernicke's encephalopathy in allogeneic bone marrow transplantation: a study of eight cases.

Wernicke's encephalopathy (WE) is a neuropsychiatric condition generally caused by acute thiamine deficiency and classically involves the triad of altered mentation, ataxia and ophthalmoplegia. It is most common among alcoholics, but several other causes have been identified, including total parenteral nutrition (TPN) use. We present eight cases of WE in patients undergoing allogeneic BMT, where thiamine deficiency was caused by a lack of vitamin supplementation during TPN administration.

Bone marrow transplantation for patients with Fanconi anemia: a study of 24 cases from a single institution.

Although bone marrow transplantation (BMT) can eliminate the hematologic manifestations of Fanconi anemia (FA), patients are unusually susceptible to complications associated with the use of cyclophosphamide (CY) in the conditioning regimen. To investigate modifications of the conditioning regimen, we reviewed the records of 24 patients with FA who received an allogeneic BMT. All patients presented with severe pancytopenia.
