We report an elderly patient with diffuse large B cell lymphoma harbouring Epstein-Barr virus that showed spontaneous regressions with subsequent relapses three times. The patient died of aspiration pneumonia without any anti-neoplastic treatment 5 years 10 months after the initial onset of lymph node swelling. In the literature, there are several reports(More)
Isolated extramedullary relapse is rare in patients with acute promyelocytic leukemia (APL) after allogeneic stem cell transplantation (SCT), and an optimal therapy for it has not been established. We describe a patient with APL who developed serially occurring extramedullary disease (EMD) after SCT. We confirmed that EMD had arisen from the recipient's APL(More)
OBJECTIVE Infarct size (IS) reduction by ischemic preconditioning (IPC) has been assessed in the heart in which coronary stenosis (CS)-induced chronic ischemia was not present. The aim of this study is to assess whether and how IS reduction by IPC is modified in the heart in which CS has occurred, and how further therapeutics, if any, modify it. METHODS(More)
Irreversibly injured cardiomyocytes are positive for terminal deoxynucleotidyl transferase nick end-labeling (TUNEL), making it controversial as to whether TUNEL-positive cardiomyocytes induced by hypoxia–reoxygenation are apoptotic (secondarily necrotic) or primarily necrotic. We investigated the relationship between plasma membrane integrity and DNA(More)
Renal amyloidosis is typically characterized by nephrotic syndrome, often with massive proteinuria and refractory peripheral edema. We report the case of a patient with renal amyloidosis associated with nephrotic syndrome who maintained remission for 6 years after undergoing high-dose chemotherapy followed by autologous peripheral blood stem-cell(More)
The efficacy of 1% chlorhexidine-gluconate ethanol and 10% povidone-iodine for skin antisepsis of central venous catheter (CVC) sites were compared among hematology patients. The CVC site colonization rates of those groups were 11.9% and 29.2%, respectively, and the catheter-associated blood stream infections were 0.75 and 3.62 per 1,000 catheter-days,(More)
A patient who had myelodysplastic syndrome (MDS) and dilated cardiomyopathy (DCM) had a transient improvement of cardiac function after peripheral blood stem cell transplantation (PBSCT). When he was admitted to hospital for PBSCT, a chest X ray showed cardiomegaly, and Tc-99m quantitative gated single photon emission computed tomography (QGS) showed(More)
Fibroblasts, the majority of non-cardiomyocytes in the heart, are known to release several kinds of substances such as cytokines and hormones that affect cell and tissue functions. We hypothesized that undefined substance (s) derived from cardiac fibroblasts may have the potential to protect against ischemic myocardium. To assess our hypothesis, using rats,(More)
A patient had multiple myeloma and associated cardiac amyloidosis, which caused diastolic dysfunction and recurrent ventricular fibrillation. After implantation of a cardioverter-defibrillator (ICD), the patient underwent autologous peripheral blood stem cell transplantation (PBSCT). The life-threatening arrhythmias, such as ventricular fibrillation,(More)
Transfusion-related acute lung injury (TRALI) is a clinical syndrome characterized by bilateral pulmonary edema in association with transfusions. We encountered a 23-year-old woman with acute lymphoblastic leukemia, in whom TRALI without anti-human leukocyte antigen class I and anti-granulocyte antibodies developed following allogeneic bone marrow(More)
