BACKGROUND AND PURPOSE The association between elevated blood pressure (BP) and hematoma enlargement in acute intracerebral hemorrhage (ICH) has not been clarified. We investigated the association between maximum systolic BP (SBP) and hematoma enlargement, measuring SBP between a baseline and a second CT scan in patients with hypertensive ICH. METHODS We(More)
INTRODUCTION The vast majority of patients with intracerebral hemorrhage (ICH) are admitted to an intensive care unit (ICU). Patients admitted to ICUs have a high risk of developing nosocomial infections, while complicating infection appears to be associated with a longer ICU stay. An increased length of ICU stay translates directly into increased costs.(More)
There have been numerous studies of the relationship between intracerebral hemorrhage (ICH) and meteorological conditions, but their conclusions have been inconsistent. Poor discrimination of ICH subtypes (primary or secondary) may have obscured the conclusions. Although most studies have analyzed seasonal or monthly variation, daily meteorological data are(More)
OBJECTIVE We assessed the cross-sectional association between sleep duration and untreated diabetes in Japanese men. METHODS Participants included 20,744 men aged 30-64 years who first visited the general hospital in Tokyo for routine health assessments during 2003-2007. Untreated diabetes was defined as not being under diabetes treatment and fasting(More)
Subarachnoid haemorrhage (SAH) patients in Fisher group 3 have a high risk of vasospasm and chronic hydrocephalus. We have provided cisternal irrigation combined with a head-shaking method for preventing vasospasm in SAH patients. We investigated 76 SAH patients in Fisher group 3 who received cisternal irrigation with head-shaking to evaluate the(More)
OBJECT Although the mechanisms underlying neurocognitive changes after carotid endarterectomy (CEA) are poorly understood, intraoperative ischemia and postoperative hemodynamic changes may play a role. METHODS Data from 81 patients who underwent unilateral CEA with routine shunt use for carotid artery stenosis were retrospectively evaluated. These(More)
OBJECT The mechanisms underlying neurocognitive changes after surgical clipping of unruptured intracranial aneurysms (UIAs) are poorly understood. The aim of this study was to investigate factors that determine postoperative cognitive decline after UIA surgery. METHODS Data from 109 patients who underwent surgical clipping of a UIA were retrospectively(More)
OBJECTIVES To examine whether a lower hematocrit was associated with a lower prostate-specific antigen (PSA), when stratifying by body mass index (BMI) in healthy men. PSA test is widely used in screening for prostate cancer. Many studies have found that PSA levels inversely correlate with BMI. It remains unclear whether hemodilution causes this inverse(More)
The mechanisms underlying post-extracranial to intracranial (EC-IC) bypass neurocognitive changes are poorly understood. Data from 55 patients who underwent a unilateral EC-IC bypass for atherosclerotic internal carotid artery (ICA)/middle cerebral artery (MCA) steno-occlusive disease were retrospectively evaluated. These patients underwent(More)
Clinical results as well as cognitive performances after extracranial to intracranial (EC-IC) bypass in conjunction with contralateral carotid endarterectomy (CEA) are poorly understood. Data from 14 patients who underwent unilateral EC-IC bypass for atherosclerotic internal carotid artery (ICA)/middle cerebral artery (MCA) steno-occlusive disease in(More)
