Human T-cell lymphotropic virus type (HTLV)-1 Tax is a viral protein that has been reported to be important in the proliferation of adult T-cell leukemia/lymphoma (ATLL) cells and to be a target of HTLV-1-specific cytotoxic T lymphocytes (CTLs). However, it is not clear how Tax-specific CTLs behave in lymph nodes of ATLL patients. The present study analyzed the immunostaining of Tax-specific CTLs. Furthermore, ATLL tumor cells are known to be positive for forkhead box P3 (Foxp3)and to have a regulatory T (Treg)-cell-like function...

BACKGROUND: Kawasaki disease (KD) is classified as a systemic vasculitis syndrome and QT interval dispersion (QTD) has been associated with cardiac involvement and disease activity in patients with cardiovasculitis. We examined whether baseline QTD could predict a response to intravenous immunoglobulin (IVIG) in KD.Methods and Results:QTD was recorded in 86 patients with KD before IVIG, who were separated into IVIG responders (R group; n=62) and nonresponders (N group; n=24). The association between baseline QTD and response to IVIG was investigated, and the predictive response value was compared with conventional risk scores from Gunma and Kurume universities...

The most common event responsible for resistance to first- and second-generation (1st and 2nd) epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) is acquisition of T790M mutation. We examined whether T790M is related to clinicopathologic or prognostic factors in patients with relapse of EGFR mutant non-small cell lung cancer (NSCLC) after treatment with 1st or 2nd EGFR-TKIs. We retrospectively reviewed the T790M status and clinical characteristics of 73 patients with advanced or recurrent NSCLC who had been treated with EGFR-TKIs and undergone rebiopsy at Kurume University Hospital between March 2005 and December 2015...

OBJECTIVE: Endothelial dysfunction is an initial step in atherosclerotic cardiovascular disease. However, involvement of vascular inflammation in endothelial dysfunction is not fully investigated in humans because of the lack of diagnostic modality to noninvasively evaluate vascular inflammation. We assessed the relationship between endothelial function and vascular inflammation evaluated by [(18)F]-fluorodeoxyglucose-positron emission tomography/computed tomographic imaging. APPROACH AND RESULTS: We examined endothelial function and vascular inflammation by flow-mediated dilation (FMD) of the brachial artery and [(18)F]-fluorodeoxyglucose-positron emission tomography/computed tomographic imaging of carotid arteries, respectively, in 145 subjects (95 men and 50 women; mean age, 61...

Corynebacterium is a genus consisting of Gram-positive, rod-shaped bacteria, that is wildly distributed in nature. We report the epidemiological characterization of Corynebacterium spp. isolated from blood specimens at the Kurume University Hospital, between June 2008 and November 2011. Twenty-two strains that were likely Corynebacterium spp. were isolated from 22 hospitalized patients, of which 12 (54.5%) were identified as Corynebacterium striatum. Minimum inhibitory concentration tests were performed after biochemical and genotypic identifications...

Pancreatic neuroendocrine tumors (P-NETs) are relatively rare. Approximately 50-90% of non-functioning P-NETs are malignant, and the only curative treatment is surgical resection. Liver and lymph node metastases often occur. In Japan, the mTOR inhibitor everolimus is now covered by the national health insurance for treatment of P-NETs, including advanced and unresectable tumors. We present a case of P-NETs with liver metastases seen at our hospital and discuss our treatment strategy for this disease. Patients with tumors≤1 cm receive follow-up observation...
