Background And Purpose: Although antiplatelets are known to be effective for secondary prevention of cerebral infarction, the number needed to treat is rather large and the effects in stroke patients with complications such as hypertension or diabetes are inadequately defined. This study was conducted to examine the effect of such complications on recurrence of cerebral infarction, and to assess the effect of cilostazol, an antiplatelet agent, in these high-risk subjects.
Methods: A post hoc subgroup analysis of the already reported Cilostazol Stroke Prevention Study, which was a placebo-controlled double-blind trial, has been carried out to clarify the influence of various complications on recurrence in the placebo group and the effects of cilostazol in 1,095 patients with noncardioembolic ischemic cerebrovascular disease.
Background And Purpose: The antiplatelet agent sarpogrelate is a selective inhibitor of 5-hydroxytryptamine receptors. The purpose of this study was to compare the efficacy and safety of sarpogrelate with those of aspirin in Japanese ischemic stroke patients.
Methods: In total, 1510 patients with recent cerebral infarction (1 week to 6 months after onset) were randomly assigned to receive either sarpogrelate (100 mg TID) or aspirin (81 mg/d).
We report a case of a right-handed 74-year-old man who showed semantic dementia with a disease duration of 19 years. He initially presented with excessive use of pronouns and semantic paraphasia at the age of 55 years. Impairment of object recognition developed 5 years after the onset.

The reshaping of sAbeta homeostasis, in particular the sAbeta42-lipoprotein interaction, takes place over normal-60's, whereas mild AD patients appear to have impaired this anti-amyloidogenic mechanism resulting in a significant increase of lipoprotein-free sAbeta42. Similar loss of function takes place in Down's syndrome patients.

Patients And Methods: Echocardiography stable state data were available for 163 of 200 consecutive autopsied patients. Of these, PASP could be estimated by extrapolation from the maximum pressure gradient in tricuspid valve regurgitation from echocardiograms in 73 cases; however, 22 cases with secondary changes attributable to left cardiac insufficiency had to be excluded.
Background: Many elderly persons without heart failure have high plasma concentrations of brain natriuretic peptide (BNP). We investigated the prognostic implications and potential causes of these increased levels.
Methods: We enrolled 111 persons aged 80 years or older who had no history of hospitalization for cardiac disease, a cardiothoracic ratio < or =55% on chest radiographs, and a serum creatinine level < or =2.
