Alberta Stroke Program Early CT Scoring of CT perfusion in early stroke visualization and assessment.

Background And Purpose: Qualitative CT perfusion (CTP) assessment by using the Alberta Stroke Program Early CT Score (ASPECTS) allows rapid calculation of infarct extent for middle cerebral artery infarcts. Published thresholds exist for noncontrast CT (NCCT) ASPECTS, which may distinguish outcome/complication risk, but early ischemic signs are difficult to detect. We hypothesized that different ASPECTS thresholds exist for CTP parameters versus NCCT and that these may be superior at predicting clinical and radiologic outcome in the acute setting.

A preliminary study of the efficacy of ondansetron in the treatment of ataxia, poor balance and incoordination from brain injury.

Background: Ataxia is caused by a variety of conditions leading to imbalance, incoordination and other disabilities. Current treatment is largely symptomatic. Ondansetron (a 5-HT3 antagonist) has been established as an anti-emetic in cancer patients, but has recently been shown to improve vertigo and cerebellar tremor in some patients.

Where do family practice patients go in case of emergency?

Objective: To determine the annual incidence of patient-defined emergencies and patients' use of emergency services at a family medicine teaching unit.

Design: Cross-sectional survey.

Setting: Hospital-based family medicine teaching unit in Montreal.

The effect of intramedullary cement on intercalary allograft reconstruction of bone defects after tumour resection: a pilot study.

Objective: A pilot study to evaluate the surgical and functional results of resection and reconstruction of diaphyseal bone tumours with cemented and uncemented intercalary allografts.

Design: A retrospective case series.

Setting: A quaternary care unit within a teaching hospital.
