1. Avaliação do método de imunofenotipagem por citometria de fluxo no diagnóstico das doenças displásicas (SMD, LMA-relacionada à mielodisplasia, LMMC e LMMJ) em adultos e crianças / Evaluation of flow cytometric immunophenotyping analysis in diagnosis of dysplastic diseases (MDS, AML with myelodysplasia-related changes; CMML and JMML) in adults and children
As síndromes mielodisplásicas (SMD) se caracterizam por terem uma hematopoese displásica, citopenias e pelo risco de progressão para leucemia mielóide aguda. O diagnóstico baseia-se na clínica e nos achados citomorfológicos da medula óssea (MO) e citogenéticos. Na fase inicial ou quando a MO é hipocelular o diagnóstico é difícil e a citogenéti

2. Estudo cromossomico em sindromes mielodisplasicas
The míelodysplastyc syndromes (MDS) can precede the development of acute nonlymphocytic leukemia (ANLL) and are classified as five different hemotological groups 1) refractory anaemia (RA), 2) refractory anaemia with ring sideroblasts (RAS), 3) refractory anaemia with excess blasts (RAEB), 4) refractory anaemia with excess blasts in transformation (RAEBt) a

3. Myelodysplastic syndrome coexisting with acute lymphoblastic leukaemia.
A 55 year old woman developed chronic myelomonocytic leukaemia (CMML) one year after she had been successfully treated for acute lymphoblastic leukaemia (ALL). When the ALL relapsed the CMML remitted only to return with further remission of the ALL. A consistent chromosomal abnormality, t(4;11), was present during both CMML and ALL phases.

4. Pericardial extramedullary haemopoiesis in chronic myelomonocytic leukaemia.
Chronic myelomonocytic leukaemia (CMML) is a myelodysplastic syndrome with a diverse clinical spectrum. A case of a 60 year old man with CMML who developed cardiac tamponade is reported. Cytological examination of the pericardial effusion fluid showed extramedullary haemopoiesis. Serous effusions are well recognised in association with this disease, but this

5. Chronic myelomonocytic leukaemia associated with T cell receptor delta gene rearrangement.
Morphological, immunophenotypic, and genetic analyses were carried out on peripheral blood, bone marrow, and pharyngeal biopsy material from a patient with chronic myelomonocytic leukaemia (CMML). Morphological analysis of bone marrow was diagnostic of CMML; immunophenotypic analysis of peripheral blood and bone marrow were negative for B and T cell antigens

6. Obstructive uropathy associated with myelomonocytic infiltration of the prostate.
A 72 year old man was diagnosed with chronic myelomonocytic leukaemia (CMML) according to the FAB group classification. He presented with symptoms of anaemia, urinary frequency, hesitancy, and nocturia. He was later admitted with acute urinary retention and acute renal failure, which resolved with treatment. A transurethral resection of the prostate was perf

7. Proapoptotic BID is required for myeloid homeostasis and tumor suppression
The proper expansion and contraction of hematopoietic cells requires tight regulation of cell death. BID, a “BH3-only” molecule, amplifies death receptor signals connecting the extrinsic to intrinsic pathways by triggering the mitochondrial pathway of apoptosis. Bid-deficient mice, as they age, spontaneously develop a myeloproliferative disorder, which p

8. Fatal myeloproliferation, induced in mice by TEL/PDGFβR expression, depends on PDGFβR tyrosines 579/581
The t(5;12)(q33;p13) translocation associated with chronic myelomonocytic leukemia (CMML) generates a TEL/PDGFβR fusion gene. Here, we used a murine bone marrow transplant (BMT) assay to test the transforming properties of TEL/PDGFβR in vivo. TEL/PDGFβR, introduced into whole bone marrow by retroviral transduction, caused a rapidly fatal myeloproliferativ

9. Intratracheal Injection into Rats of Size-graded Silica Particles
An experiment is described in which suspensions of size-graded silica particles of less than 1 μ, 1 to 3 μ, and 2 to 5 μ nominal size ranges and of equal surface area (600 sq. cm./ml.) were injected intratracheally into rats. After four months the rats were killed and the lungs were examined histologically for the grade of fibrosis and chemically for the

10. Loss of heterozygosity 4q24 and TET2 mutations associated with myelodysplastic/myeloproliferative neoplasms
Chromosomal abnormalities are frequent in myeloid malignancies, but in most cases of myelodysplasia (MDS) and myeloproliferative neoplasms (MPN), underlying pathogenic molecular lesions are unknown. We identified recurrent areas of somatic copy number–neutral loss of heterozygosity (LOH) and deletions of chromosome 4q24 in a large cohort of patients with m

11. Defective neutrophil function and microbicidal mechanisms in the myelodysplastic disorders.
Neutrophil function studies have been carried out in a series of 44 patients with primary myelodysplastic syndromes (MDS). In vitro tests of phagocytosis and killing of Candida guilliermondii and Staphylococcus aureus identified 13 patients with abnormal neutrophil function at presentation and a further 10 who developed abnormalities during the course of the

12. Globin chain synthesis in myelodysplastic syndromes.
Globin chain synthesis was studied in the reticulocytes of 30 patients with various myelodysplastic syndromes (MDS) to determine the alpha:beta globin chain synthetic ratio and its probable prognostic value. The mean (SD) value of the total alpha:beta ratio was 0.82 (0.45) ranging from 0.05 to 1.73. The same ratio in 10 normal controls was 1.01 (0.04). This
