Biphenotypic acute leukemia (BAL) is a rare entity that comprises 0.5-3% of all acute leukemias and probably arises from multipotent progenitor cells. The optimal approach for BAL therapy is unknown. Thus, it is important to elucidate the origin of the neoplastic cells for determination of the appropriate therapy. We report the case of a 41-year-old man(More)
Dear Editor, Reversible cerebral vasoconstriction syndrome (RCVS) has been recognized as a syndrome of diverse conditions characterized by the reversible multifocal narrowing of cerebral arteries [1, 2]. RCVS has been detected in more patients in recent years because of the growing availability of noninvasive MRI and magnetic resonance angiography (MRA)(More)
We examined the biological functions of the gene Cbl in erythropoietin (EPO) signaling using Cbl-deficient F-36P human erythroleukemia cells by the introduction of the Cbl siRNA expression vector. Knockdown of Cbl promoted EPO-dependent proliferation and survival of F-36P cells, especially at a low concentration of EPO (0.01U/mL), similar to serum(More)
Primary gastric lymphoma is relatively rare in the scope of gastric malignancies. Here we report a case of diffuse large B-cell primary gastric lymphoma treated successfully with the CD20 monoclonal antibody, rituximab, alone. Because the patient had a complication of severe liver dysfunction due to hepatitis C virus induced-liver cirrhosis and(More)
We present a 22-year-old male diagnosed with pro T-acute lymphoblastic leukemia (ALL). His laboratory test showed 181,900/microL of WBC complicated with lymphoadenopathy, pleural effusion, pericardial effusion and hepatosplenomegaly at the onset. Flow cytometry analysis of the leukemic cells showed cCD3+, CD7+, CD2+, CD1a-, CD3-, CD5-, CD4-, CD8-, CD34+,(More)
Recently, the importance of home medical care has been stressed. But patients, those assisting them and home care nurses do not attach much importance to oral and dental care in home medical care. When we visit patients who have asked for dental treatment through home care nurses, they appeared to have very poor oral hygiene; cavities were uncared for,(More)
The adequate dose of imatinib has not been defined for the Japanese population. Indeed, about half of patients experience mild to moderate adverse events due to this drug, some of which result in intolerance. We reviewed a patients' cohort treated with imatinib in our hospital in 2007 for chronic myelogeneous leukemia (CML). The cohort included 14 patients(More)
Bortezomib, a proteasome inhibitor, has been used for patients with refractory multiple myeloma. We present a 58-year old man who had IgG-gamma-type multiple myeloma, refractory for MP (melphalan-predonisolone) and VAD (vincrisitine-doxorubicin-dexamethasone) therapy. He was complicated with reactivation of varicella-zoster virus (VZV) 4 weeks before(More)
