BACKGROUND Mortality in patients with myelodysplastic syndromes (MDS) is high, and patients are likely to require hospitalizations, emergency department (ED) visits, and transfusions. The relationships between these events and the MDS complications of anemia, neutropenia, and thrombocytopenia are not well understood. PATIENTS AND METHODS A total of 1864 patients registered in the United State...
Hemophagocytic lymphohistiocytosis (HLH) is a clinicopathologic condition characterized by high fever, hepatosplenomegaly, cytopenia, hyperferritinemia, and increased hemophagocytic macrophage proliferation and activation in the reticuloendothelial system. Primary HLH is familial and is a fatal disease that begins during early childhood. Secondary HLH may be acquired after intense activation of...
Drug hypersensitivity reactions can lead to different clinical pictures depending on the underlying immunological mechanism. Diagnosis tests are already available to assess the most frequent drugs hypersensitivity reactions, which are mediated by specific IgE or T cells. However, it remains challenging to diagnose type 2 hypersensitivity reactions (T2HR), which can lead to severe cytopenia and ...
DOI: 10.5581/1516-8484.20130069 Myelodysplastic syndrome (MDS) is a heterogeneous group of diseases characterized by ineffective and dysplastic hematopoiesis and pancytopenia in the peripheral blood(1). Minimal diagnostic criteria for MDS have been discussed by several working groups. The term idiopathic cytopenia of undetermined significance (ICUS) has been proposed to define patients who do n...
BACKGROUND We retrospectively analysed charts of patients with blood ferritin level >5000 µg/l. The aim of the study was to look for the likelihood of haemophagocytic lymphohistiocytosis (HLH) in these patients. METHODS Forty-two patients demonstrated hyperferritinaemia and could be evaluated. The diagnosis of HLH was based on a recently published HScore and an earlier diagnostic algorithm. ...
Exposure to ionizing radiation alone (radiation injury, RI) or combined with traumatic tissue injury (radiation combined injury, CI) is a crucial life-threatening factor in nuclear and radiological accidents. As demonstrated in animal models, CI results in greater mortality than RI. In our laboratory, we found that B6D2F1/J female mice exposed to (60)Co-γ-photon radiation followed by 15% total-...
Myelodysplastic syndromes (MDS) comprise a heterogeneous group of myeloid neoplasms characterized by peripheral cytopenia, dysplasia, and a variable clinical course with about 30% risk to transform to secondary acute myeloid leukemia (AML). In the past 15 years, diagnostic evaluations, prognostication, and treatment of MDS have improved substantially. However, with the discovery of molecular ma...
A well-studied effect of irradiation is a lesion the hematopoietic system, manifested by cytopenic changes in peripheral blood varying severity. decrease concentration cells those working under these conditions has always been reason for conducting an in-depth examination order to exclude radiation genesis and identify true cause changes. However, current Order Ministry Health Russian Federatio...
Rhabdomyosarcoma caused bone marrow metastasis cases are among the rarest reported in literature. Similar to literature, clinical presentation of our patient mimicked acute leukemia, and leukoerythroblastosis peripheral smear test cytopenia hemogram raised suspicion hematological malignancy initially.1,2 The diagnosis made by immunohistochemical staining biopsy. primary tumor field could not be...
