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)
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)
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)
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)
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)
We investigated a foodborne norovirus outbreak in a hospital and an attached long-term care facility (LTCF). An at-risk group of 698 people was identified, which included staff, hospital patients, LTCF residents, and adult daycare users who shared consumption of food prepared in a central kitchen. Three different diets were prepared in three separate(More)
PURPOSE Several studies show that prostate specific antigen inversely correlates with body mass index. Hemodilution may be responsible for the lower prostate specific antigen in obese men. Hematocrit is the most popular indicator of plasma volume. We examined the effect of hematocrit changes on prostate specific antigen in healthy men during 2 years. We(More)
BACKGROUND Spinal cerebrospinal fluid (CSF) leaks, which are considered a cause of intracranial hypotension, generally do not cause any local symptoms. Although symptoms are key elements for further evaluation, few studies have examined symptom predictors of intracranial hypotension. The aim of this study was to determine what symptoms are predictors of CSF(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)
