Although abdominal obesity and related metabolic abnormalities are hypothesized to promote colorectal carcinogenesis, direct confirmation of this effect is required. Here, we examined the relation early-stage neoplasia visceral fat area markers insulin resistance.Subjects were participants in a comprehensive health screening conducted at Hitachi Health Care Center, Ibaraki, Japan. During 3-year period (2004-2007), total 108 patients with neoplasia, including 22 early cancer, identified among...
The purpose of our study was to use an artificial neural network differentiate benign from malignant pulmonary nodules on high-resolution CT findings and evaluate the effect output performance radiologists using receiver operating characteristic analysis.We selected 155 cases with less than 3 cm (99 56 nodules). An used distinguish basis seven clinical parameters 16 radiologic that were extracted by attending subjective rating scales. In observer test, 12 (four radiologists, four radiology...
To retrospectively identify successive changes in peripheral lung adenocarcinoma that feature dominant ground-glass opacity (GGO) at computed tomography (CT) and correlate with biomolecular markers.The institutional review board approved this retrospective study, all 25 patients provided informed consent. Patients adenocarcinomas smaller than 3 cm diameter whom tumor growth could be evaluated CT before surgery were included. Two thoracic radiologists by analyzing GGO type (pure or mixed)...
Highlights•MOG improves disease control in patients with ATLL before allo-HSCT.•MOG administration allo-HSCT increases severe acute GVHD, leading to a high incidence of transplantation-related mortality.•Shorter intervals from the last MOG were associated development GVHD.AbstractMogamulizumab (MOG), humanized anti-CC chemokine receptor 4 (CCR4) monoclonal antibody, has recently played an important role treatment adult T cell leukemia/lymphoma (ATLL). Because CCR4 is expressed on normal...
To determine the reproducibility of quantitative chemical shift-based water-fat separation method with a multiecho gradient echo sequence [iteraterative decomposition water and fat asymmetry least-squares estimation quantitation (IDEAL-IQ)] for assessing bone marrow fraction (FF); to evaluate variation FF at different sites; investigate its association age menopause.31 consecutive females who underwent pelvic iterative 3-T MRI were included in this study. Quantitative using IDEAL-IQ four...
Static electric dipole moments of nondegenerate systems probe mass scales for physics beyond the Standard Model well those reached directly at high energy colliders. Discrimination between different models, however, requires complementary searches in atomic-molecular-and-optical, nuclear and particle physics. In this report, we discuss current status prospects near future a compelling suite such experiments, along with developments needed encompassing theoretical framework.
This study aimed to clarify the usefulness of screening for malignancies using CT before initiation biologic and targeted synthetic DMARDs (b/tsDMARDs) in patients with active RA.We examined 2192 RA who underwent plain scans prior b/tsDMARDs. The sensitivity detecting malignancy was measured compared that regular (physical examination X-ray). We then evaluated clinical characteristics, prognosis treatment concomitant malignancies. Additionally, we determined incidence rate were initiated on...
Basal interventricular septum (IVS) hypertrophy (BSH) is characterized by a reduced aortoseptal angle and thickened basal IVS. The BSH shape suggests compression the longitudinally elongated ascending aorta (pseudohypertrophy), further suggesting possibility of surgical aortic wall shortening to improve BSH. We report case 77-year-old woman with an asymptomatic dissecting thoracic aneurysm clear Surgical root replacement longitudinal clearly improved BSH, demonstrating beneficial effects on...
A clinicopathologic and immunohistochemical review was made of seven cases angiomyofibroblastoma. The patients were middle‐aged women who had a slowly growing mass, measuring 1.5–6 cm in maximum dimension, located sub‐cutaneously the vulva. tumors well‐demarcated characterized by well‐vascularized, alternating hyper‐cellular hypocellular edematous areas composed bland, plump spindle‐ or oval‐shaped stromal cells frequently aggregated around small blood vessels. An epithelioid appearance seen...
BackgroundMeasuring the size of invasiveness on computed tomography (CT) for T descriptor was deemed important in 8th edition TNM lung cancer classification. We aimed to correlate maximal dimensions solid portions using both and mediastinal window settings CT imaging with pathologic (> 0.5 cm) adenocarcinoma patients.Materials MethodsThe study population consisted 378 patients a histologic diagnosis situ (AIS), minimally invasive (MIA), (IVA)-lepidic, IVA-acinar and/or IVA-papillary,...
The purpose of this article is to compare tomosynthesis with radiography and MRI the wrist hand for evaluating bone erosion in patients rheumatoid arthritis (RA).Twenty consecutive an established diagnosis RA five control were included study. They underwent radiography, tomosynthesis, bilateral within a week. mean total dose was 0.13 0.25 mGy, respectively. evaluation performed according Outcome Measures Rheumatology Clinical Trials recommendations. Bone on images from three modalities...
Abstract Intravascular lymphoma (IVL) is a rare type of extranodal in which the cells proliferate exclusively lumina small vessels. Here, we report clinicopathological study 13 cases IVL diagnosed at our institution between March 1999 and July 2007, evaluated clinical characteristics, usefulness random skin biopsy response to chemotherapy containing rituximab. Three patients were autopsy. The most common features unexplained fever, neurological deterioration, respiratory failure, poor...
