Clinical TrialBedside assessment of cerebral perfusion reductions in patients with acute ischaemic stroke by near-infrared spectroscopy and indocyanine green.
To detect perfusion reductions in patients with acute cerebral infarcts using near-infrared spectroscopy (NIRS) with indocyanine green (ICG) as tracer. ⋯ Measurement of interhemispheric differences in ICG kinetics by NIRS detects perfusion reductions in patients with acute middle cerebral artery infarction. This non-invasive bedside test is rapid, repeatable, without major side effects, and avoids transportation of critically ill patients.

Clinical TrialAbductor sign: a reliable new sign to detect unilateral non-organic paresis of the lower limb.
To test a new neurological sign, the "abductor sign," which can distinguish between organic and non-organic leg paresis using synergic movements of the bilateral hip abductors. ⋯ The abductor sign is a useful test to detect non-organic paresis, because (1) it is difficult for a hysterical patient to deceive the examiner, (2) the hip abductor is one of the most commonly involved muscles in pyramidal weakness, and (3) the results are easily visible as movement or non-movement of the unabducted leg.

The epidemiology of multiple sclerosis in Devon: a comparison of the new and old classification criteria.
To determine the prevalence of multiple sclerosis in Devon and compare the new McDonald classification guidelines with the Poser criteria currently used. ⋯ This is first survey to use the new recommended guidelines and compare these criteria with the Poser classification. The difficulties encountered with applying the new criteria in research are highlighted, as are the differences between the new and old criteria. This study reports one of the highest prevalences in the south of the UK, adding support for a north-south divide being a step effect rather than a latitudinal gradient.

Predictive value of Glasgow Coma Scale after brain trauma: change in trend over the past ten years.
Age and the Glasgow Coma Scale (GCS) score on admission are considered important predictors of outcome after traumatic brain injury. We investigated the predictive value of the GCS in a large group of patients whose computerised multimodal bedside monitoring data had been collected over the previous 10 years. ⋯ The admission GCS lost its predictive value for outcome in this group of patients from 1997 onwards. The predictive value of the GCS should be carefully reconsidered when building prognostic models incorporating multimodality monitoring after head injury.

ReviewIdiopathic intracranial hypertension: 12 cases treated by venous sinus stenting.
The high pressures documented in the intracranial venous sinuses in idiopathic intracranial hypertension (IIH) could be the result of focal stenotic lesions in the lateral sinuses obstructing cranial venous outflow. ⋯ The importance of venous sinus disease in the aetiology of IIH is probably underestimated. Lateral sinus stenting shows promise as an alternative treatment to neurosurgical intervention in intractable cases.
