The normal counterparts of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) have not been accurately identified. We immunohistochemically analyzed 10 PTCL-NOS cases to examine the expression of the master regulators of T-cell differentiation and of surface antigens, including chemokine receptors. All cases were positive for the master(More)
OBJECTIVE Clostridium difficile is a major cause of diarrhea in hospitalized patients. Although pseudomembranes are crucial evidence for diagnosis of C. difficile-associated diarrhea (CDAD), some cases do not show any pseudomembranes. The aim of this study was to verify the hypothesis that pseudomembranes are not generated in immunosuppressed patients(More)
AIMS To clarify the features of the background electroencephalographic (EEG) activities in clinically well preterm infants born at less than 27 weeks gestation and to outline their chronological changes with increasing postconceptional age (PCA). METHODS EEGs of clinically well premature infants born at less than 27 weeks gestation were recorded during(More)
In B-cell malignancies, genes implicated in B-cell differentiation, germinal center formation, apoptosis, and cell cycle regulation are juxtaposed to immunoglobulin loci through chromosomal translocations. In this study, we identified the BTB and CNC homology 2 (BACH2) gene as a novel translocation partner of the immunoglobulin heavy chain (IGH) locus in a(More)
Subcutaneous panniculitis-like T cell lymphoma (SPTL) is a rare subtype of non-Hodgkin lymphoma for which a definitive therapeutic strategy has not been established yet. We report a case of chemotherapy-resistant SPTL with hemophagocytic syndrome (HPS) which was successfully treated with cyclosporine A (CsA) plus methylprednisolone (mPSL), and also reviewed(More)
Mother-to-infant transmission of hepatitis C virus (HCV) was analyzed by sequencing of viral RNA and semiquantitative polymerase chain reaction following ultracentrifugation of maternal sera. In two mother-infant pairs, the hypervariable region 1 (HVR1) and carboxyl terminus of envelope 1 (E1) were sequenced. Both viral sequences in the infants were less(More)
We retrospectively investigated the prognostic impact of high-risk cytogenetic abnormalities (CAs) on the outcome of treatment with bortezomib plus dexamethasone (BD) in 43 relapsed/refractory (Rel/Ref) multiple myeloma patients. Fluorescence in situ hybridization (FISH) analysis identified del(13q) in 25 patients, t(4;14) in 14, t(14;16) in 4, 1q21(More)
Protein-losing enteropathy (PLE) is characterized by gastrointestinal loss of serum protein. It is usually caused by hypersecretion from a tumor, ulcer, or long standing lymphangiectasia. However, we report a 47-year-old man of peritoneal nodal follicular lymphoma who developed PLE with none of them. Oozing of whitish fluid from duodenal bulbar mucosa was(More)
OBJECTIVE Clostridium difficile-associated diarrhea (CDAD) is a well-known iatrogenic infection with typical endoscopic features including pseudomembranes and intervening normal mucosa. Clinically, diarrhea frequently occurs, but occurrence of hematochezia is rare. The objective of this study was to investigate the background and endoscopic features of CDAD(More)
OBJECTIVES Although rituximab therapy is not considered to be closely associated with infection, there have been reports of serious infections in patients treated with rituximab. We performed a statistical retrospective analysis to clarify the risk factors for infection in patients receiving rituximab therapy. METHODS A retrospective study of data from(More)
