Background Hematopoietic stem cell (HSC) transplantation is the only treatment providing long-term cure in acute myeloblastic leukemia. At the apex of the hematopoietic system, quiescent HSCs escape to chemotherapeutic treatments and therefore can regenerate the entire blood system after drug exposure. Nevertheless, the consequence of repeated chemotherapy regimen on HSC function remains to be ...

Three patients with idiopathic sideroblastic anemia of variable duration developed acute leukemia. In two the leukemia was morphologically and histochemically myeloblastic, in one lymphoblastic. With combination chemotherapy remission was achieved in all three. The remission inductions were complicated by long periods of bone marrow suppression and the duration of remissions was brief (3, 2 and...

Morphological identification of acute leukemia is a powerful tool used by hematologists to determine the family of such a disease. In some cases, experienced physicians are even able to determine the leukemia subtype of the sample. However, the identification process may have error rates up to 40% (when classifying acute leukemia subtypes) depending on the physician's experience and the sample ...

We report a case of human infection caused by the hyphomycete Myceliophthora thermophila. A 7-year-old male with neurofibromatosis (type 1) was diagnosed in 1987 with acute myeloblastic leukemia associated with the chromosomal abnormality monosomy 7. The patient experienced multiple serious infections over a three-year period before expiring in 1990 while in the end stage of leukemia. Autopsy f...

Expression of the granulocyte-macrophage colony-stimulating factor (GM-CSF) gene was studied by Northern blot analysis in normal human hematopoietic cells and a series of leukemias. GM-CSF messenger (m)RNA was detected in activated T cells, but not in normal bone marrow cells, monocytes, or nonactivated T cells. In contrast, leukemic cells from 11 of 22 cases of acute myeloblastic leukemia expr...

Results Three patients were diagnosed as acute lymphoblastic leukemia who received total body irradiation and chemotherapy. The other two patients were diagnosed as acute myeloblastic leukemia. The mean age at HSCT was 8.0 ± 4.2 years. Four out of five patients developed chronic graft-versus-host disease (GVHD) and treated with steroid more than 2 years. The mean age at diagnosis of DM was 15.8...

Acute myeloblastic leukemia (AML) is a highly fatal malignant bone marrow disease. Physicians, dentists and all other healthcare professionals should be aware of sinister oral signs and symptoms in order to early diagnosis and referral of patients. Here we report a case of AML who presented with oral ulcers. Ulcers developed after a parrot bite, which initially misled the physicians. Unfortunat...

The blast cells from four patients with these patients revealed the inclusions to acute leukemia and Down’s syndrome be single membrane-bound structures conwere found to contain unusual inclusions taming electron-dense amorphous debris, which manifested similar morphologic membranous substance, and virus-like and cytochemical characteristics. Ultraparticles. structure studies of the blasts from...
