Posterior versus anterior circulation infarction: how different are the neurological deficits?

Background And Purpose: Distinguishing between symptoms of posterior circulation infarction (PCI) and anterior circulation infarction (ACI) can be challenging. This study evaluated the frequency of symptoms/signs in the 2 vascular territories to determine the diagnostic value of particular symptoms/signs for PCI.

Methods: Neurological deficits were reviewed and compared from 1174 consecutive patients with a diagnosis of PCI or ACI confirmed by magnetic resonance imaging in the Chengdu Stroke Registry.

Characteristics, treatment and outcome of ischemic stroke with atrial fibrillation in a Chinese hospital-based stroke study.

Background: There is scant information on characteristics, treatment, functional outcome and case fatality of ischemic stroke with atrial fibrillation (AF) in China.

Methods: For this study, first-ever ischemic stroke patients who were admitted within 1 month of stroke onset during the period of March 2002 through December 2008 were included. Data on ischemic stroke patients were collected which included: demographics, risk factors, treatment administered, stroke-related complications and 3-month, 6-month and 1-year death and disability.

Association between renal function and clinical outcome in patients with acute stroke.

Background And Purpose: Data on the association between renal dysfunction and outcome in patients with stroke are controversial and scarce. We investigated the predictors of renal dysfunction upon admission and the association between renal dysfunction and clinical outcome in patients with acute stroke in a hospitalized Chinese population.

Methods: 1,758 acute stroke patients were consecutively enrolled into the study.

One-year case fatality and disability after posterior circulation infarction in a Chinese hospital-based stroke study.

Background And Purpose: Controversy exists as to whether posterior circulation infarction (PCI) has a poorer outcome compared to anterior circulation infarction (ACI). We aimed to investigate whether PCI had different clinical outcomes from ACI in Chinese patients with ischemic stroke.

Methods: Data on ischemic stroke patients with ACI or PCI were collected including demographics, risk factors and 1-month, 3-month, and 1-year case fatality and disability (defined as modified Rankin Scale 3-5).

[Incidence rates of human immunodeficiency virus and syphilis as well as the rate of retention in a 6-month follow-up study of female sex workers in areas with heavy drug use in Xichang of Sichuan province, China].

Objective: To investigate the human immunodeficiency virus (HIV) and syphilis incidence rates as well as the retention rate in a cohort with 6-month follow-up study among female sex workers (FSWs).

Methods: From December, 2004, to January, 2005, a community-based baseline survey was conducted to recruit 343 FSWs for a prospective cohort study in Xichang county of Sichuan province, China. Follow-up visits were conducted at 6 months to analyze risk factors associated with cohort retention for subjects' baseline sociodemographic and sexual behavioral characteristics.
