[A case report of familial dyskeratosis congenital. Case report].

Dyskeratosis congenita (DC) is a hereditary syndrome of bone marrow failure, which develops because of telomeres defects and combines with cancer predisposition. Its classical clinical features are skin pigmentation, nail dystrophy, oral leukoplakia (skin-mucosa triad). The goal is to describe the algorithm of diagnosis, clinical specificities of DC and specific treatment for cases of DC in one family.

Diagnostic significance of flow cytometry scales in diagnostics of myelodysplastic syndromes.

Background: Myelodysplastic syndromes (MDS) can present a challenge for clinicians. Multicolor flow cytometry (MFC) can aid in establishing a diagnosis. The aim of this study was to determine the optimal MFC approach for MDS.

[Numbers of early CD34+ progenitors of bone marrow hematopoiesis in patients with diffuse large B-cell lymphoma].

Aim: To estimate the number of early progenitors of bone marrow (BM) hematopoiesis in patients with diffuse large B-cell lymphoma (DLBCL) in the late period after high-dose chemotherapy (HDCT) according to the mNHL-BFM-90 program.

Subjects And Methods: The investigators analyzed the results of BM immunophenotypic and histological studies in 40 patients (median age, 57 years) with DLBCL who received HDCT according to the mNHL-BFM-90 program at the Hematology Research Center (HRC), Ministry of Health of the Russian Federation (MHRF), in the period 2002 to 2009. A comparison group consisted of 19 patients (median age, 70 years) treated according to the CHOP/R-CHOP program at HRC, MHRF, in the same period.

[Late myelotoxicity of high-dose chemotherapy according to the modified NHL-BFM-90 program in adult patients with diffuse large B-cell lymphoma].

Aim: to evaluate late myelotoxicity (MT) relate to high-dose chemotherapy (CT) according to the modified NHL-BFM-90 (mNHL-BFM-90) program in adult patients with diffuse large B-cell lymphoma (DLBCL).

Subjects And Methods: The results of a complex clinical, laboratory, and instrumental examination, including cytologic, histologic, and routine cytogenetic studies of the bone marrow (BM), were analyzed in 40 DLBCL patients treated according to the mNHL-BFM-90 program in the National Research Center for Hematology (NRCH), Ministry of Health of the Russian Federation (MHRF), in 2002 to 2009; among them, there were 20 men and 20 women (median age, 57 years). A comparison group consisted of 19 patients who had received high-dose СНОР/R-СНОР-21 CT in HRC, MHRF, in the same period of time; out of them, there were 8 men and 11 women (median age, 70 years).
