BACKGROUND AND PURPOSE Asymptomatic microbleeds shown by T2*-weighted MR imaging are associated with small-artery diseases, especially with intracerebral hemorrhage. Few studies have focused on the prevalence of microbleeds in patients with recurrent stroke. We investigated frequency of microbleeds in patients with recurrent stroke and association of(More)
PURPOSE Polymorphisms in the interleukin 1 alpha (IL1A) and IL1B gene regions were previously associated with keratoconus in a Korean population. In the present study, we investigated whether the IL1A and IL1B polymorphisms are associated with keratoconus in a Japanese population. METHODS A total of 169 Japanese patients with keratoconus and 390 Japanese(More)
BACKGROUND AND PURPOSE Previous studies have shown microbleeds to be a risk factor for intracerebral hemorrhage and white matter hyperintensity (WMH) to be a risk factor for ischemic stroke. This study was performed to determine whether combinations of the presence or absence of microbleeds and advanced WMH are risk factors for subsequent recurrent stroke(More)
PURPOSE Toll-like receptor 4 (TLR4) is a transmembrane receptor that mediates immune responses to exogenous and endogenous ligands and interacts with heat shock proteins, which are reportedly involved in normal tension glaucoma (NTG). This study was undertaken to investigate whether TLR4 polymorphisms are associated with NTG. METHODS Two hundred fifty(More)
BACKGROUND AND PURPOSE Although accumulating evidence suggests the presence of microbleeds as a risk factor for intracerebral hemorrhage (ICH), little is known about its significance in anticoagulated patients. The aim of this study was to determine whether the presence of microbleeds is associated with recurrent hemorrhagic stroke in patients who had(More)
The purpose of the present study was to investigate sequential changes in serum soluble thrombomodulin (sTM) concentrations in patients with acute cerebral infarction (ACI), and to correlate sTM concentrations with the severity of ACI evaluated by Japan Stroke Scale. Eighty-three consecutive patients with ACI were enrolled, and blood examinations were(More)
Multivariate and single variable analyses were employed to investigate the recovery mode of aphasia in right-handed patients with putaminal hemorrhage on the left side. Speech disturbance was evaluated using the standard language test for aphasia (SLTA) at intervals of 1, 3 and 6 months after the ictus. Recovery was assessed in relation to age, gender,(More)
BACKGROUND AND PURPOSE Although MBs, ICH, and LI are secondary to cerebral microangiopathy, it remains unclear whether the location of subsequent ICH/LI corresponds to the previous location of MBs. We performed this study to clarify the positional relationship between recurrent ICH/LI and previously detected MBs. MATERIALS AND METHODS We evaluated(More)
Both leukoaraiosis and asymptomatic microbleeds are associated with small-artery diseases. Although an association between hyperhomocysteinemia and leukoaraiosis has been reported, no studies have evaluated the association between total homocysteine (tHcy) level and presence of microbleeds in stroke patients. We evaluated the association between tHcy level(More)
PURPOSE Sarcoidosis is a heterogeneous and multisystem granulomatous disorder. The etiology still is uncertain, but the disease currently is thought to be triggered by various genetic as well as environmental factors. Recently, an association between sarcoidosis and the butyrophilin-like 2 (BTNL2) gene located in close proximity to the HLA-DRB1 gene was(More)
