Assessment of symptoms in a concussion management programme: method influences outcome.

Context: Monitoring of subjective symptoms is the foundation of all sport concussion management programmes. The purpose of this study is to examine methodological variables that impact symptom reporting during baseline testing.

Objective: To investigate how the administration method of a concussion assessment tool (self-report vs interview) affects the report of symptoms.

Utility of TOMM Trial 1 as an indicator of effort in children and adolescents.

Although measuring test compliance in a pediatric neuropsychological evaluation is important, increasing demands on clinicians' time and the need for efficiency during assessments may make it difficult to routinely include effort testing. This study investigated whether performance on Trial 1 of the Test of Memory Malingering (TOMM) is predictive of overall performance in children and adolescents with neurological disorders. Participants included 53 children and adolescents between six and 19 years (mean age = 12.

Sport-related concussions: knowledge translation among minor hockey coaches.

Objective: The objective of this study was to investigate minor hockey coaches' knowledge base of sport-related concussions.

Design: Cross-sectional survey.

Setting: Subjects independently completed the written survey at preseason organizational meetings.

Incidence of radiocontrast nephropathy in patients undergoing acute stroke computed tomography angiography.

Background And Purpose: Minimal research has evaluated the renal safety of emergent computed tomography angiography (CTA) procedures, consecutive contrast medium application, and the long-term outcome in acute stroke patients. We investigated the incidence of contrast-induced renal impairment in these populations.

Methods: We retrospectively reviewed patients with acute stroke syndrome who received a CTA of the brain with or without the neck within 24 hours from onset of symptoms.

Perfusion MRI abnormalities in speech or motor transient ischemic attack patients.

Background And Purpose: Transient ischemic attack (TIA) patients may deteriorate rapidly. MRI is being increasingly used to assess such patients. One possible mechanism of neurological worsening is the presence of perfusion abnormalities.
