Specific DWI lesion patterns predict prognosis after acute ischaemic stroke within the MCA territory.
Apart from diffusion-weighted imaging (DWI) lesion volume and diffusion-perfusion mismatching, there is limited information about neuroradiological predictors of early prognosis after an ischaemic stroke. This study sought to identify specific DWI lesion patterns that would help prediction of early prognosis of three different endpoints: unstable hospital course, recurrence of stroke, and poor neurological outcome at 90 days after ischaemic stroke. ⋯ The results of the present study indicate that the DWI lesion pattern may help in recognition of the likely differences in the early prognostic endpoints after ischaemic stroke, and DWI analysis may guide targeted interventions to prevent negative outcomes.

Whiplash following rear end collisions: a prospective cohort study.
The purpose of this study was to investigate the factors which predict neck pain initially and at 1 year following a rear end collision. ⋯ Demographic variables and the presence of a compensation suit show the strongest correlation with acute and chronic neck pain following rear end collisions.

Headache as the only neurological sign of cerebral venous thrombosis: a series of 17 cases.
Headache is the most frequent symptom in cerebral venous thrombosis (CVT), and usually the first. However, it has rarely been reported as the only symptom of CVT. ⋯ The pathogenesis of isolated headache in CVT in the absence of intracranial hypertension, SAH, meningitis or intracerebral lesion is unknown but may involve changes in the walls of the occluded sinus. Hence MRI/MRV should be used to look for signs of CVT in all patients with recent headache (progressive or thunderclap) even when the CT scan and CSF examination are normal.
