Right atrial strain measured by 2D speckle-tracking echocardiography is associated with poor cardiac outcomes in patients with heart failure.

Right heart failure (HF) is a poor prognostic factor in patients with HF. The right atrial (RA) function has attracted less attention than the right ventricular (RV) function. The association of RA reservoir strain evaluated by 2D speckle-tracking echocardiography (2DSTE) with clinical outcomes in patients with HF remains unclear.

Left atrial strain time integral evaluated by two-dimensional speckle tracking predicts left atrial appendage dysfunction in patients with acute ischemic stroke.

Cardioembolic stroke is a serious disease with poor prognosis, whose main embolic source is the left atrial appendage (LAA). Left atrial (LA) strain evaluated by the two-dimensional (2D) speckle tracking technique has been proposed. However, the commonly used peak LA strain reflects only LA reservoir function.

A case of a transcatheter valve-in-valve implantation using balloon expandable valve for failed SOLO SMART stentless bioprosthetic valve.

Unlabelled: A 74-year-old man who had undergone surgical aortic valve replacement with the SOLO SMART stentless bioprosthetic valve 25 mm (LivaNova PLC, London, UK) and mitral valve replacement with MOSAIC 29 mm (Medtronic, Minneapolis, USA) 4 years previously was diagnosed with congestive heart failure, and transferred to our hospital. Echocardiography revealed severe aortic regurgitation caused by degraded bioprosthetic valve. He required continuous dobutamine administration to maintain hemodynamics.

[Complete cytogenetic response to interferon-alpha in a patient with chronic myelogenous leukemia undergoing hemodialysis].

We describe a complete cytogenetic response to interferon-alpha in a patient with chronic myelogenous leukemia undergoing chronic hemodialysis. Although IFN-alpha therapy has been applied to patients with chronic hepatitis C receiving hemodialysis, the pharmacokinetics of IFN-alpha in patients with poor renal function still remain unclear. In the present patient, the serum IFN-alpha concentration remained high even 48 hours after injection (42.

Rearrangement of the BCL6 gene in B-cell lymphoid neoplasms: comparison with lymphomas associated with BCL2 rearrangement.

We report a series of B-cell neoplasms with regard to rearrangement of the BCL6 gene on chromosome band 3q27. Southern blot analysis using probes from the major translocation cluster (MTC) region of the BCL6 revealed rearrangement in 21/197 patients (10.7%) with B-cell neoplasms studied at presentation, and 11/25 patients (44%) first studied at relapse.

Involvement of the BCL3 gene in two patients with chronic lymphocytic leukemia.

The t(14;19)(q32;q13) is a recurring translocation found in some patients with chronic lymphocytic leukemia (CLL), and the t(14;19) juxtaposes the BCL3 gene on chromosome 19 with the immunoglobulin heavy chain gene (IGH) locus on chromosome 14. Genomic DNAs from 49 patients with chronic B-cell leukemia and the related lymphomas were examined by Southern blot hybridization using 2 separate probes, named p alpha 1.4P and p alpha .

[Clinical and cytological features of acute myelogenous leukemia with 8; 21 chromosome translocation].

Eight cases of acute myelogenous leukemia with (8; 21) translocation were reported. As recently reported, they showed following features: M2 morphology in FAB classification (all 8 patients), abnormal granulocyte maturation, i.e.

Involvement of bcl-2 gene in Japanese follicular lymphoma.

A t(14;18) (q32;q21) chromosome translocation is closely associated with the follicular lymphoma, which is prevalent in the United States, and the t(14;18) causes the juxtaposition of a bcl-2 gene on chromosome 18 with an immunoglobulin heavy-chain gene locus on chromosome 14. Genomic DNAs from 30 Japanese patients with follicular lymphoma were examined for the molecular features by Southern blot hybridization. Using probe b for the major breakpoint cluster region of a bcl-2 gene, the rearrangements were detected in eight patients.

A novel translocation, t(2;5)(p23;q35), in childhood phagocytic large T-cell lymphoma mimicking malignant histiocytosis.

We report a novel chromosome translocation--t(2;5)(p23;q35) or its variant, t(2;5;13)(p23;q35;q12)--in 3 patients with peripheral T-cell lymphoma. All 3 were female children who had peripheral lymphadenopathy without organomegaly and underwent complete remission with or without chemotherapy. Their tumors were characterized histologically by predominant large cells, at times showing phagocytosis, and immunologically by peripheral T-cell phenotype and expression of Ki-1 antigen and epithelial membrane antigen (EMA).

Significance of extra 18q- chromosome in Japanese t(14;18)-positive lymphoma.

Karyotype evolution of t(14;18)-positive lymphoma was studied in 13 Japanese patients. The extra 18q- chromosome, found in six of ten patients with complex karyotypes, was the most common change subsequent to a t(14;18)(q32;q21) chromosome translocation. The additional change was interpreted as being a duplication of an 18q- derived from a t(14;18).

[Autosomal translocation and associated male infertility].

Four balanced autosomal reciprocal translocations were found through mitotic chromosome analysis among 72 subfertile males, 27 with azoospermia and 45 with sperm counts below 40 X 10(6)/ml. They were 46, XY, t(3; 20; 21) with azoospermia, 46, XY, t(14; 21) with sperm counts below 1 X 10(6)/ml, 46, XY, t(1; 19) lqh+ with azoospermia and 46, XY, t(3; 16) with sperm counts 27 X 10(6)/ml. Histological, cytogenetic and hormonal analysis were performed.
