Mastocytosis is a myeloproliferative neoplasm characterized by clonal expansion of abnormal mast cells, ranging from the cutaneous forms of the disease to mast cell leukemia. In a significant proportion of patients, systemic mastocytosis (SM) coexists with another hematologic malignancy, termed systemic mastocytosis with an associated hematologic nonmast(More)
Hypereosinophilic syndrome is a rare entity that can develop secondary to overproduction of eosinophilopoietic cytokines or as idiopathic disease. Cardiac involvement, which occurs often, is divided into 3 stages, the latter of which is nonreversible and leads to severe heart failure. Early detection and treatment of the syndrome is essential. For this(More)
Signal transducer and activator of transcription (STAT) proteins have been intensively studied in hematologic malignancies, and the efficacy of agents against STATs in lymphomas is already under research. We investigated the expression of total STAT5 and STAT5b in peripheral blood samples of patients with chronic lymphocytic leukemia (CLL) in correlation(More)
BACKGROUND The tumor protein p53 (TP53) gene may be inactivated through 17p13 deletion, somatic mutations, or both. In chronic lymphocytic leukemia (CLL) although 17p13 deletion is correlated with poor prognosis, the role of sole TP53 mutations remains controversial. MATERIALS AND METHODS We carried out a mutation analysis of TP53 gene in 72 patients with(More)
BACKGROUND/AIM The hypomethylating agent 5-azacytidine has been the standard-of-care for patients with higher-risk myelodysplastic syndrome (MDS) during the past few years. Its efficacy has been proven in large clinical trials, and its safety has been shown to be superior to that of conventional treatments. PATIENTS AND METHODS We conducted a(More)
Dear Editor, Spontaneous hematogenous non-surgical staphylococcal meningitis is a rare entity with high mortality. Risk factors for Staphylococcus aureus bacteremia (SAB) include age, HIV infection, hemodialysis, and intravenous drug use (IDU) [1], but the risk of meningitis among patients with SAB is <1% [2], and the only identifiable risk factor for(More)
Tyrosine kinase inhibitors (TKIs), namely imatinib mesylate (IM) and recently approved second-generation TKIs dasatinib and nilotinib, are currently considered the treatment of choice for newly-diagnosed chronic phase chronic myelogenous leukemia (CP-CML). Although treatment with TKIs has not yet been proven curative, it certainly accomplishes a sustained(More)
