Association between ApoE phenotypes and telomere erosion in Alzheimer's disease.

Although several reports suggest that Alzheimer's disease (AD) is associated with shortened telomere length, the clinical relevance of this has not yet been fully elucidated. This study was conducted to clarify the correlation of telomere length with clinical characteristics and ApoE phenotypes in 74 AD patients. Telomere length was determined from genomic DNA extracted from whole blood by quantitative real-time polymerase chain reaction.

Clinical results and issues of acute myeloid leukemia in elderly patients aged 75 years and older.

Aim: Clinical outcomes of acute myeloid leukemia (AML) in elderly patients still remain unsatisfactory and the optimal treatment has yet to be clearly established. This report describes the results of a retrospective study of clinical outcomes and prognostic factors of AML in patients aged 75 years and older. In addition, we aimed to elucidate the situation of patients with AML accompanied by dementia, which has been largely ignored in previous studies.

Vascular risk factors and progression in Alzheimer's disease.

Aim: To determine whether vascular risk factors such as hypertension, diabetes and hypercholesterolemia affect the progression of Alzheimer's disease (AD).

Methods: We followed up 150 consecutive outpatients with probable AD for 24-60 months. Severity of cognitive impairment was assessed using the Mini-Mental State Examination (MMSE).

Peripheral T-cell lymphoma presenting as myelofibrosis with the expression of basic fibroblast growth factor.

Myelofibrosis is often observed in chronic myeloproliferative disorders (CMPD), but non-Hodgkin's lymphoma with diffuse myelofibrosis is rare. We describe an elderly case with peripheral T-cell lymphoma-unspecified (PTCL) presenting as diffuse myelofibrosis. Bone marrow biopsy revealed infiltration of atypical lymphocytes and diffuse myelofibrosis without any increase in megakaryocytes.

[An elderly autopsy case of chronic myelomonocytic leukemia with infiltration of a giant liver cyst and multiple organs].

A 78-year-old man was referred to his local hospital at the beginning of July 2006 with low grade fever and cough, and was admitted on August 22 with pneumonia. Hematology tests on admission revealed leukocytosis, anemia, and thrombocytopenia, so he was subsequently transferred to our hospital on August 24. A diagnosis of chronic myelomonocytic leukemia (CMML) was made from the hematological findings and he was given hydroxycarbamide from September 7.

[The efficacy and adverse effects of rituximab with CHOP or THP-COP in old-old and extremely old patients with diffuse large B cell lymphoma].

Aim: We examined the efficacy and adverse effects of rituximab with CHOP (cyclophosphamide, doxorubicin, vincristin, prednisone) or THP-COP (pirarubicin, cyclophosphamide, vincristin, prednisone) in previously untreated old-old and extremely old patients with diffuse large B cell lymphoma (DLBCL).

Methods: Subjects were 13 initial DLBCL patients consisting of 7 men and 8 women with a median age of 79 years (range 75-91 years). These patients received CHOP or THP-COP plus 375mg/m2 rituximab intravenously given on the day before each cycle.

[A case of anaplastic large cell lymphoma associated with Epstein-Barr virus infection, representing clinicopathological features of malignant histiocytosis].

An 82-year-old woman was admitted with fever and anorexia. Aggravated pancytopenia and liver dysfunction suggested the presence of disseminated intravascular coagulation. The serum ferritin level increased to 9,100 ng/ml.
