Treatment-related Myelodysplastic Syndrome (t-MDS) is well known and serious complication of cancer treatment. However, MDS cases caused by therapy of common nonmalignant diseases are unusual and represent diagnosic and therapeutic challenge. We experienced a case of secondary MDS, possibly induced by trimetazidine dihydrochloride, which was spontaneously resolved by discontinuance of the drug....
Design and Methods The aim of this study was to investigate outcome and risk factors in patients with therapy-related myelodysplastic syndrome or acute myeloid leukemia who underwent allogeneic stem cell transplantation. Between 1981 and 2006, 461 patients with therapy-related myelodysplastic syndrome or acute myeloid, a median age of 40 years and a history of solid tumor (n=163), malignant lym...
An unusual and hitherto unreported complication of myelodysplastic syndrome is reported: the "pseudo-Koebner phenomenon." The skin lesions were characterised by exuberant "fleshy" masses at the sites of intravenous cannulation and skin trauma, and by histological evidence of chronic inflammation with focal necrosis and abscess formation. No evidence of dermal infiltration by malignant haemopoie...
Large granular lymphocyte leukemia (LGL) is often associated with immune cytopenias and can co-occur in the context of aplastic anemia (AA) and myelodysplastic syndromes (MDS). We took advantage of the recent description of STAT3 mutations in LGL clonal expansions to test, using sensitive methods, for the presence of these mutations in a large cohort of 367 MDS and 140 AA cases. STAT3 clones ca...
Only a limited number of cases of Behçet's disease and hematological malignancies have been reported in the literature. We report the case of a 45 year old female patient with Behçet's disease who developed myelodysplastic syndrome, refractory anemia with excess blasts in transformation subtype, with complex chromosomal abnormalities, including excess of chromosome 8, following several years of...
CONTEXT The prognosis of severe aplastic anemia has improved since the introduction of bone marrow transplantation and treatment with antithymocyte globulin. In contrast to the success of these protocols, studies with long term follow-up have shown the occurrence of clonal diseases such as paroxysmal nocturnal hemoglobinuria, myelodysplastic syndrome and acute leukemia in aplastic anemia. CAS...
Several clinical forms: the most frequents are JCML and the monosomy 7 syndrome; these disorders have some common features: JCML is defined by clinical and cytological observations; 6 to 24% of JCML children show monosomy 7 in the bone marrow; monosomy 7 syndrome is a cytogenetic-defined entity. The therapy related cases of monosomy 7 had been exposed to alkylating agents, they have a myelodysp...
Accumulating evidence implicates innate immune activation in the pathobiology of myelodysplastic syndromes. A key myeloid-related inflammatory protein, S100A9, serves as a Toll-like receptor ligand regulating tumor necrosis factor-α and interleukin-1β production. The role of myelodysplastic syndrome-related inflammatory proteins in endogenous erythropoietin regulation and response to erythroid-...
Interstitial deletion of chromosome 5q is the most common chromosomal abnormality in myelodysplastic syndromes. The catalogue of genes involved in the molecular pathogenesis of myelodysplastic syndromes is rapidly expanding and next-generation sequencing technology allows detection of these mutations at great depth. Here we describe the design, validation and application of a targeted next-gene...
In various industries benzene is used for cleaning, stain removal, and dilution and as an adhesive. The petrochemical industry uses benzene as a raw material for styrene, alkyl benzene, and caprolactam. Moreover, aromatic compounds are added to gasoline as a substitute for alkyl lead compounds. Although atmospheric lead pollution is reduced, the concentration of benzene released into the air is...
