OBJECTIVE Early hematoma expansion is a known cause of morbidity and mortality in patients with intracerebral hemorrhage (ICH). The goal of this study was to identify clinical predictors of ICH growth in the acute stage. MATERIALS AND METHODS We studied 201 patients with acute (<6 h) deep ganglionic ICH. Patients underwent CT scan at baseline and hematoma(More)
In the airways of severe asthmatics, an increase of neutrophils and eosinophils is often observed despite high-dose corticosteroid therapy. We previously reported that interleukin-8-stimulated neutrophils induced trans-basement membrane migration (TBM) of eosinophils, suggesting the link between neutrophils and eosinophils. Concentrations of(More)
Blunt cerebrovascular injury (BCVI) is known to be a potentially fatal complication of cervical spine injury (CSI). Methods for screening the appropriate population remain to be elucidated, especially in Japan. This retrospective study was conducted to predict the risk factors relevant to BCVIs. Among 92 patients with CSI transferred to our institution from(More)
OBJECTIVE CT-diagnosed emphysema is associated with poor prognosis in chronic obstructive pulmonary disease (COPD). Its clinical impacts on prognoses of asthma with chronic airflow obstruction (CAO) are not well known. We sought to compare mortalities and prognostic factors in COPD and asthma with CAO by the presence or absence of CT-diagnosed emphysema. (More)
BACKGROUND AND PURPOSE Fresh thrombus formation at the coil-parent artery interface around the neck of aneurysms is sometimes observed during coil embolization of cerebral aneurysms. We retrospectively analyzed the factors associated with local acute thrombus formation from the data of patients treated over a period of 5 years at our institute. METHODS(More)
OBJECTIVES The characteristics of serum catecholamine concentration at the hyper-acute phase of aneurysmal subarachnoid hemorrhage (SAH) and its relationship between patient outcome and delayed vasospasm were investigated. METHODS Patients with aneurysmal SAH (170) were prospectively studied between August 2008 and June 2011. Baseline demographic data and(More)
BACKGROUND In practice, it is difficult to compare the effectiveness of traditional antihypertensive treatment with that of health promotion in reducing incidence rate of cardiovascular disease (IRCVD, events/year). This simulation study compared the effectiveness of two approaches to reducing IRCVD in a sample population: a traditional approach, in which(More)
We report a rare case of ectasia of both pericallosal arteries in a non-hypertensive 37-year-old female, whose internal carotid arteries and vertebrobasilar arteries were normal. The computed tomography (CT) showed irregular calcifications in the midline in the frontal region extending to the corpus callosum, which became partially enhanced along the course(More)
