A 62-year-old male patient was admitted for close monitoring of anemia (hemoglobin level, 8.2 g/dl). Hemolytic anemia was observed; however, the direct antiglobulin test (DAT) result (standard tube method) was negative.

We encountered a 63-year-old woman with CMV oophoritis who had been treated for Burkitt's lymphoma. Positron emission tomography/computed tomography performed after chemotherapy showed a high F-fluoro-2deoxy-D-glucose uptake in both ovaries, which required distinguishing relapse.

Immune thrombocytopenia (ITP) has been reported to be one of the rare adverse events caused by vaccination with MMR (measles-mumps-rubella) vaccine and influenza vaccine. In addition, ITP has been reported to occur in a small number of cases associated with the COVID-19 messenger ribonucleic acid (mRNA) vaccine.

Although the use of second-generation tyrosine kinase inhibitors is now available for initial cases, a small number of patients with CML unfortunately still experience progression to the accelerated or blastic phase of the disease. We recently managed a patient with chronic-phase CML, who developed a T315 mutation early in the course of treatment with dasatinib and progressed to the lymphoid blastic phase.
View Article and Find Full Text PDFImmunosuppressants are widely used to treat patients with rheumatoid arthritis (RA), and their adverse effects have been known to cause other iatrogenic immunodeficiency-associated lymphoproliferative disorders (OIIA-LPDs). We report a patient with RA who had been treated with methotrexate (MTX) and tacrolimus (TAC) and who developed whole body lymphadenopathy. We simultaneously confirmed angioimmunoblastic T-cell lymphoma (AITL) through a right cervical lymph node biopsy and Epstein-Barr virus-positive B-cell lymphoproliferative disorder (EBV-positive B-LPD) through a bone marrow examination.

Steroids are very effective for treatment of AMF and the disease has a good prognosis and should be distinguished from primary myelofibrosis. CASE REPORT A 49-year-old man with bleeding and petechial hemorrhage of the extremities presented to our institution.

In Japan, the disease-specific Japan Rhino-conjunctivitis Quality of Life Questionnaire (JRQLQ) and the generic SF-36 Health Survey (SF-36) has been used. The aim of this study is to investigate more profitable QOL by using both the disease-specific questionnaire and the non-disease-specific questionnaire together.

It is reported that the QOL is an important outcome in the JCP treatment. This study aimed to evaluate the QOL in patients with JCP by means of the SF-8 Health Survey (Japanese Version), a new, even shorter generic health survey.

Introduction of wild-type (WT)-CKIepsilon into interleukin-3 (IL-3)-dependent 32D cells increased the sensitivity to genotoxic stresses, such as gamma-irradiation, etoposide, and IL-3 deprivation, whereas kinase-negative (KN)-CKIepsilon suppressed it. Contrary to KN-CKIepsilon, WT-CKIepsilon attenuated the IL-3-induced activation of Akt with the increase of PTEN activity.
View Article and Find Full Text PDFTwo closely related casein kinase I (CKI) isoforms, CKIdelta and CKIepsilon, are ubiquitously expressed in many human tissues, but their specific biologic function remains to be clarified. Here, we provide the first evidence that CKIepsilon is involved in hematopoietic cell differentiation. CKIepsilon, but not CKIdelta, was down-regulated along with human granulocytic differentiation.

Methods: Eight patients with a history of epistaxis found to have an intranasal hemangioma were studied.

A member of the largest family of receptor protein kinases, EphB6, lacks its intrinsic kinase activity, but it is expressed in normal human tissues. To investigate the physiological function of EphB6, we generated EphB6 deficient mice. EphB6(-/-) mice developed normally, revealed no abnormality in general appearance, and were fertile.

We report a case of papillary cystadenocarcinoma arising from the minor salivary gland in the anterior portion of the tongue of a 72-year-old male patient with a history of adenocarcinoma of the colon and prostate. Further, we discussed histopathological and clinical features of this lesion, and reviewed the literature.
