[Posterior reversible encephalopathy syndrome following acute pancreatitis during chemotherapy for acute monocytic leukemia].

We describe an 18-year-old man with acute leukemia who presented with posterior reversible encephalopathy syndrome (PRES) shortly after developing acute pancreatitis. On day 15 after the third consolidation course with high-dose cytarabine, treatment with broad-spectrum antibiotics was initiated for febrile neutropenia. On day 16, he developed septic shock, and subsequently, acute respiratory distress syndrome (ARDS).

[Diffuse large B-cell lymphoma with hemolytic crisis developed twenty years after the onset of Evans syndrome].

A 65-year-old woman was diagnosed with Coombs-positive autoimmune hemolytic anemia (AIHA) and pure red cell aplasia (PRCA) in May 1992. One month later, her PRCA went into remission following treatment but she developed idiopathic thrombocytopenic purpura and was diagnosed with Evans syndrome. Although her condition resolved with administration of prednisolone and azathioprine, it was necessary to continue treatment with gradual tapering over the following two decades.

[Cerebral toxoplasmosis after umbilical cord blood transplantation diagnosed by the detection of anti-toxoplasma specific IgM antibody in cerebrospinal fluid].

Cerebral toxoplasmosis is a rare, potentially fatal, complication of hematopoietic cell transplantation. Early definitive diagnosis is very difficult and it may be associated with a poor prognosis. Herein, we describe a 60-year-old woman who developed cerebral toxoplasmosis after cord blood transplantation for myelodysplastic syndrome.

iview: an interactive WebGL visualizer for protein-ligand complex.

Background: Visualization of protein-ligand complex plays an important role in elaborating protein-ligand interactions and aiding novel drug design. Most existing web visualizers either rely on slow software rendering, or lack virtual reality support. The vital feature of macromolecular surface construction is also unavailable.

Water-soluble undenatured type II collagen ameliorates collagen-induced arthritis in mice.

Earlier studies have reported the efficacy of type II collagen (C II) in treating rheumatoid arthritis (RA). However, a few studies have investigated the ability of the antigenic collagen to induce oral tolerance, which is defined as active nonresponse to an orally administered antigen. We hypothesized that water-soluble undenatured C II had a similar effect as C II in RA.

Serial measurements associated with an amelioration of acute heart failure: an analysis of repeated quantification of plasma BNP levels.

Background: The magnitude of improvement of acute heart failure achieved during treatment varies greatly among patients. We examined changes in the plasma B-type natriuretic peptide (BNP) levels of patients with acute heart failure and attempted to elucidate the clinical factors associated with amelioration of acute heart failure.

Methods And Results: The study population consisted of 208 consecutive patients admitted to our institution with acute heart failure.

Limited impact of passive non-neutralizing antibody immunization in acute SIV infection on viremia control in rhesus macaques.

Background: Antiviral antibodies, especially those with neutralizing activity against the incoming strain, are potentially important immunological effectors to control human immunodeficiency virus (HIV) infection. While neutralizing activity appears to be central in sterile protection against HIV infection, the entity of inhibitory mechanisms via HIV and simian immunodeficiency virus (SIV)-specific antibodies remains elusive. The recent HIV vaccine trial RV144 and studies in nonhuman primate models have indicated controversial protective efficacy of HIV/SIV-specific non-neutralizing binding antibodies (non-NAbs).

Successful treatment of both acute leukemia and active Crohn's disease after allogeneic hematopoietic stem cell transplantation using reduced-intensity conditioning with fludarabine and busulfan: a case report.

Background: A 32-year-old man diagnosed with acute myelomonocytic leukemia (M4) concurrently had active Crohn's disease (CD) that was refractory to azathioprine and anti-tumor necrosis factor.

Case Report: He underwent an allogeneic bone marrow transplantation from a one HLA-DR allele-mismatched unrelated donor to achieve the first complete remission of leukemia. The conditioning regimen consisted of fludarabine (180 mg/m(2)) and busulfan (8.

Refractoriness to platelet transfusion in acute myeloid leukemia correlated with the optical density of anti-platelet factor 4/heparin antibodies.

A small number of reports have described cases of heparin-induced thrombocytopenia complicating hematological disorders with impaired platelet production. We describe the case of a 66-year-old woman with acute myeloid leukemia who exhibited unexplained refractoriness to platelet transfusion, while receiving heparin flushes, and was found to have anti-platelet factor 4 (PF4)/heparin antibodies with high optical density (OD) values (>2 units) detected by an enzyme-linked immunosorbent assay. After cessation of heparin flushes, her refractoriness to platelet transfusion resolved.

[Angioimmunoblastic T cell lymphoma complicated with endocapillary proliferative glomerulonephritis].

A 30-year-old female developed fever and multiple lymphadenopathy in September 2011. Her symptoms improved with antibiotic treatment. However, she again presented with fever and multiple lymphadenopathy in December 2011.

Prognostic factors and outcomes of unrelated bone marrow transplantation for Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ALL) pre-treated with tyrosine kinase inhibitors.

Background: The treatment and prognosis of Acute Lymphoblastic Leukemia (ALL), including Philadelphia chromosome positive ALL (Ph+ALL), a poor prognostic factor, has changed with the introduction of tyrosine kinase inhibitors (TKIs). Nevertheless, allogeneic hematopoietic cell transplantation (allo-HCT) is still recommended as the first-line curative treatment. To date, no study has investigated the prognostic factors and outcomes of unrelated bone marrow transplantation (u-BMT) for Ph+ALL following pre-transplant treatment with a TKI-containing regimen.

[Acute transverse myelitis after allogeneic bone marrow transplantation for acute lymphoblastic leukemia--a case report].

Transverse myelitis is an inflammatory disorder of the spinal cord that results in motor, sensory, and autonomic dysfunction. Herein, we describe a 40-year-old Japanese female who developed acute transverse myelitis (ATM) after an unrelated bone marrow transplantation for Philadelphia-positive acute lymphoblastic leukemia in molecular complete remission. Approximately 90 days after transplantation, she suffered from paresthesias, sphincter dysfunction, and lower extremity weakness.

6p subtelomere deletion with congenital glaucoma, severe mental retardation, and growth impairment.

Submicroscopic deletion of the 6p subtelomere has recently been recognized as a clinically identifiable syndrome. A distinct phenotype has emerged consisting of developmental delay/mental retardation, language impairment, hearing loss, and ophthalmologic, cardiac, and craniofacial abnormalities, including hypertelorism, midface hypoplasia, small nose, and high arched palate. We describe here a patient with 6p subtelomere deletion associated with congenital glaucoma, severe mental retardation, and growth impairment.

Characteristics of a granular electronic system in Heusler-type Fe2+xV1-xAl.

We report comprehensive measurements of the magnetic, transport, and thermal properties of the Heusler-type compound Fe2+xV1-xAl, with x values near the ferromagnetic quantum critical point, xc ∼ 0.05. At T ∼ 60 K, a prominent Schottky-like anomaly appeared in the specific heat; this anomaly was correlated with a smaller pseudo-gap formation in magnetic susceptibility, magnetoresistance, and thermoelectric power.

[Retrospective analysis of eltrombopag for the treatment of refractory primary immune thrombocytopenia in Japan].

Eltrombopag, an oral thrombopoietin receptor agonist, is a novel drug that can be used in cases with previously-treated primary immune thrombocytopenia (ITP). In this study, we retrospectively analyzed 22 Japanese ITP patients treated in four hospitals. A responder was defined as a patient achieving a platelet count between 50,000/μl and 400,000/μl, at 75% or more of on-treatment assessments.

A multicenter clinical study evaluating the confirmed complete molecular response rate in imatinib-treated patients with chronic phase chronic myeloid leukemia by using the international scale of real-time quantitative polymerase chain reaction.

Achievement of complete molecular response in patients with chronic phase chronic myeloid leukemia has been recognized as an important milestone in therapy cessation and treatment-free remission; the identification of predictors of complete molecular response in these patients is, therefore, important. This study evaluated complete molecular response rates in imatinib-treated chronic phase chronic myeloid leukemia patients with major molecular response by using the international standardization for quantitative polymerase chain reaction analysis of the breakpoint cluster region-Abelson1 gene. The correlation of complete molecular response with various clinical, pharmacokinetic, and immunological parameters was determined.

Clinical factors predicting the response of acute graft-versus-host disease to corticosteroid therapy: an analysis from the GVHD Working Group of the Japan Society for Hematopoietic Cell Transplantation.

Systemic corticosteroid therapy is recommended as a first-line treatment for acute graft-versus-host disease (GVHD). We performed a retrospective study to identify the factors affecting the response of grade II to IV acute GVHD to systemic corticosteroid therapy using the Japanese national registry data for patients who received first allogeneic hematopoietic cell transplantation with bone marrow (BM) (n = 1955), peripheral blood stem cells (PBSCs) (n = 642), or umbilical cord blood (UCB) (n = 839). Of 3436 patients, 2190 (63.

[Acute myeloid leukemia with monosomy 7 and inv(3)(q21q26.2) complicated with central diabetes insipidus].

A 20-year-old female presented with thirst, polyposia, and polyuria and was referred to our hospital because of leukocytosis and anemia. Bone marrow aspiration revealed 66.8% myeloperoxidase-positive blasts and trilineage myelodysplasia.

Dasatinib maintenance therapy after allogeneic hematopoietic stem cell transplantation for an isolated central nervous system blast crisis in chronic myelogenous leukemia.

A 22-year-old male with Ph-positive chronic myelogenous leukemia (CML) was started on treatment with imatinib. After 12 months of therapy, he achieved a complete cytogenetic response (CCyR). Although the CCyR persisted in his bone marrow, he developed an isolated CML blast crisis in his central nervous system (CNS) after 29 months of therapy.

Risk factors affecting cardiac left-ventricular hypertrophy and systolic and diastolic function in the chronic phase of allogeneic hematopoietic cell transplantation.

Chronic impairment of cardiac function can be an important health risk and impair the quality of life, and may even be life-threatening for long-term survivors of allogeneic hematopoietic cell transplantation (HCT). However, risk factors for and/or the underlying mechanism of cardiac dysfunction in the chronic phase of HCT are still not fully understood. We retrospectively investigated factors affecting cardiac function and left-ventricular hypertrophy (LVH) in the chronic phase of HCT.

Reaction temperature variations on the crystallographic state of spinel cobalt aluminate.

In this study, we report a rapid and simple technique for obtaining cobalt aluminate having a spinel structure. The products were prepared from a hydroxide precursor synthesized by coprecipitation of cobalt (Co(2+)) and aluminum (Al(3+)) nitrates with an alkaline solution. The chosen precursor enabled low temperature fabrication of cobalt aluminate with a spinel structure by sintering it for 2 hours at low temperatures (>400 °C).

Transient isolated marked elevation of midregion parathyroid hormone fragments in an infant.

We describe here a Japanese male infant who transiently showed a marked elevation of midregion parathyroid hormone (M-PTH) fragments in serum with no increase in full-length 1-84 amino acid PTH and carboxy-terminal PTH fragments. He presented with a large anterior fontanel, delayed closure of the anterior fontanel, and mild short stature at 4 months old; he was normocalcemic with a normal urine calcium/creatinine ratio and absent subperiosteal bone resorption on X-ray film. Serum levels of M-PTH fragments were in >3200 pg/mL but logarithmically decreased with age.
