Multicentric Castleman disease (MCD) describes a heterogeneous group of disorders involving systemic inflammation, characteristic lymph node histopathology, and multi-organ dysfunction because of pathologic hypercytokinemia. Whereas Human Herpes Virus-8 (HHV-8) drives the hypercytokinemia in a cohort of immunocompromised patients, the etiology of(More)
IgG4-related disease is a recently recognized systemic syndrome characterized by mass-forming lesions with lymphoplasmacytic infiltration, increase in the number of IgG4(+) cells in affected tissues and elevation of serum IgG4 levels. In 2009, we were the first to report skin lesions in patients with IgG4-related disease, but no large case series has been(More)
Castleman's disease, an uncommon lymphoproliferative disorder, can be difficult to differentiate from immunoglobulin (Ig) G4-related disease. The latter is typically characterized by elevated serum IgG4 levels and abundant IgG4-positive cells. However, multicentric Castleman's disease can also have elevated serum IgG4 levels and even fulfill the(More)
Recently, atypical Castleman's disease (CD) was reported in Japan. This disease is considered as TAFRO syndrome or non-idiopathic plasmacytic lymphadenopathy (IPL), a constellation of clinical symptoms, namely, thrombocytopenia, anasarca, fever, reticulin fibrosis, and organomegaly without hyper-γ-globulinemia. Histopathologically, this disease is similar(More)
The effects of cholecystokinin-8 (CCK-8) and pentagastrin on insulin and glucagon secretion were studied in conscious sheep. Intravenous infusions of CCK-8 (3 to 1000 pmol kg-1 min-1 for 30 minutes) induced a dose-dependent increase in plasma insulin, but did not alter plasma glucagon concentration. The threshold dose of CCK-8 for stimulation of insulin(More)
Sixty-six adult patients with hematologic malignancies underwent haploidentical hematopoietic stem cell transplantation (haplo-HSCT) without T cell depletion. The patients were preconditioned with a reduced intensity regimen, and tacrolimus was used for graft-versus-host disease (GVHD) prophylaxis. Successful engraftment occurred in 60 patients (90.1%) and(More)
The effects of cholecystokinin (CCK)-8, either alone or together with the CCK antagonist, proglumide on both exocrine and endocrine pancreatic responses were examined in conscious sheep. Intravenous infusions of CCK-8 (120 pmol/kg/min for 40 min) with vehicle (0 mumol/kg/min proglumide) significantly increased both amylase output in pancreatic juice and(More)
A 49-year-old female patient previously treated for scleritis and uveitis-induced cataract in the right eye presented with a subretinal white lesion in the same eye. With a preliminary diagnosis of choroidal tumor, enucleation of the eyeball was performed in accordance with the patient's request. Histologic and immunohistologic examinations were consistent(More)
B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma (BCLu-DLBCL/CHL), also known as gray-zone lymphoma, has overlapping clinical and biological characteristics of both diffuse large B-cell lymphoma and classical Hodgkin lymphoma (CHL). These lymphomas are typically associated with(More)
Diffuse large B-cell lymphoma (DLBCL) is the most common form of non-Hodgkin's lymphoma. Although many investigations have been performed on the prognostic factors of DLBCL, no reports have focused on localized nodal DLBCL. We examined the prognostic significance of 39 Japanese patients with localized nodal DLBCL with special reference to the germinal(More)
