Cervical artery dissection--clinical features, risk factors, therapy and outcome in 126 patients.
The highly variable clinical course of cervical artery dissections still poses a major challenge to the treating physician. This study was conducted (1) to describe the differences in clinical and angiographic presentation of patients with carotid and vertebral artery dissections (CAD, VAD), (2) to define the circumstances that are related to bilateral arterial dissections, and (3) to determine factors that predict a poor outcome. Retrospectively and by standardised interview, we studied 126 patients with cervical artery dissections. ⋯ This study emphasises the potential dangers of chiropractic manipulation of the cervical spine. Probably owing to the systematic use of forceful neck-rotation to both sides, this treatment was significantly associated with bilateral VAD. Patients with dissection-related cervical artery occlusion had a significantly increased risk of suffering a disabling stroke.

Clinical TrialTime course of the effect of a bolus dose of intrathecal baclofen on severe cerebral spasticity.
Continuous intrathecal administration of baclofen with implanted programmable pump systems is recommended in the treatment of severe spasticity of cerebral origin. Prior to pump implantation, a baclofen bolus test (BBT) is used to assess the effectiveness of intrathecal baclofen using clinical scales such as the Modified Ashworth Scale (MAS). In the literature, the time and period of maximum effect of a bolus dose of intrathecally administered baclofen in patients with cerebral spasticity is variously reported. ⋯ The lowest mean MAS scores were found 4 hours after BBT. The findings suggest that the greatest effect of BBT on cerebral spasticity occurs between 2 and 8.5 hours, with a maximal effect at 4 hours after intrathecal baclofen injection. Clinical scales used to determine the effect of BBT should thus be carried out during this period-ideally at 4 hours after baclofen injection.

For the diagnosis of aphasia early after stroke, several screening tests are available to support clinical judgment. None of these tests enables the clinician to assess the underlying linguistic deficits, i. e. semantic, phonological and syntactic deficits, which provides indispensable information for early therapeutic decisions. The ScreeLing was designed as a screening test to detect semantic, phonological and syntactic deficits. The ScreeLing's sensitivity, specificity and accuracy in detecting aphasia and semantic, phonological and syntactic deficits were determined. ⋯ The ScreeLing is an accurate test that can be easily administered and scored to detect aphasia in the first weeks after stroke. Furthermore, the ScreeLing is suitable for revealing underlying linguistic deficits, especially semantic and phonological deficits.

This was a hospital-based cohort study aiming at determining the occurrence rate of post-stroke seizures and the associated risk factors. From 27 July 1996 to 16 June 1998, the first 1000 consecutive patients in the acute stroke registry were retrospectively reviewed for one year after acute stroke to identify seizure occurrence. The demographic data, seizure onset time, seizure type, drug treatment, response to medication, electroencephalogram findings and cranial computed tomogram findings were collected. ⋯ Seizures occurred in 3.4% of patients within one year after the onset of stroke. This percentage of seizure occurrence and associated risk factors were similar to other studies. However, intracerebral and subarachnoid haemorrhage were not shown to be risk factors in our study.

Comparative StudyChronic dysimmune neuropathy. A subclassification based upon the clinical features of 102 patients.
The Chronic Dysimmune neuropathies (CDN) are a clinically heterogeneous group of polyneuropathies united by their presumed immune mediated aetiology. At present such neuropathies are classified as Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), Multifocal Motor Neuropathy (MMN) and the Neuropathies in association with serum Paraproteins (Paraproteinaemic Neuropathies). This classification fails to recognise other distinctive syndromes and is limited by heterogeneity within, and overlap between, subgroups. ⋯ Patients with chronic development of Motor Sensory Demyelinating Neuropathy respond less well to steroids than those with a subacute onset. An association was found between elderly patients with Subacute Motor Sensory Demyelinating Neuropathy and carcinomas. Within any clinical subgroup patients behave similarly regardless of the presence of associated paraproteins or nerve specific antibodies.
