Chronic myelomonocytic leukemia (CMML) is a rare hematopoietic malignancy of childhood. To define the clinical and hematologic characteristics of the disease, we performed a retrospective analysis of 110 children given the diagnosis CMML irrespective of karyotype. Median age at diagnosis was 1.8 years. Neurofibromatosis type 1 was known in 14% and other clinical abnormalities in 7% of the child...

BACKGROUND Leptospirosis in dogs is occasionally associated with a hemorrhagic syndrome, the pathophysiology of which is not fully understood. HYPOTHESIS/OBJECTIVES To characterize hematologic, hemostatic, and thromboelastometric abnormalities in dogs with leptospirosis and to study their association with hemorrhagic diatheses and outcomes. ANIMALS Thirty-five client-owned dogs. METHODS A...

Hematologic abnormalities occur in the majority of patients with acquired immunodeficiency syndrome (AIDS). Infection of the hematopoietic progenitor cells has been proposed as a potential explanation. In this study, different bone marrow cell populations, including the CD34+ hematopoietic progenitor cells, were purified by a fluorescence-activated cell sorter (FACS) and analyzed for the presen...

A wealth of studies has highlighted the biological complexity of hematologic malignancies and the role of dysregulated signal transduction pathways. Along with the crucial role of genetic abnormalities, epigenetic aberrations are nowadays emerging as relevant players in cancer development, and significant research efforts are currently focusing on mechanisms by which histone post-translational ...

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is diagnosed by three criteria including cutaneous drug eruption, hematologic abnormalities, and systemic involvements. The hematologic abnormalities include presence of atypical lymphocytes or eosinophilia. The systemic involvements include lymphadenopathy, hepatitis, interstitial nephritis, interstitial pneumonia, or carditis....

Several inherited human syndromes have combined platelet, auditory, and/or pigment abnormalities. In the mouse the pallid pigment mutant has abnormalities of the otoliths of the inner ear together with a bleeding abnormality caused by platelet storage pool deficiency (SPD). To determine if this association is common, two other mouse pigment mutants, muted and mocha, which are known to have inne...

Cytogenetic analysis was performed on B-cell mitogen-stimulated cells from 36 patients with symptomatic hairy cell leukemia. Evaluable metaphases were achieved from 30 patients, and (67%) showed clonal abnormalities. Recurrent chromosomal aberrations involving chromosomes 1, 2, 5, 6, 11, 19, and 20 were found. The abnormalities were mostly deletions and inversions, whereas translocations and nu...
