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.

Comparative StudyIncidence of amyotrophic lateral sclerosis in southern Italy: a population based study.
While the incidence of amyotrophic lateral sclerosis (ALS) is similar across the world (range, 1.0 to 2.5/100,000), a latitude gradient from north to south has been observed. ⋯ ALS incidence is within a narrow range across countries, with a peak between 65 and 75 years and a higher incidence in men. A north to south latitude gradient of ALS incidence is not supported by the results of cohort studies.

Case ReportsThe first evaluation of brain shift during functional neurosurgery by deformation field analysis.
Stereotactic surgery is based on a high degree of accuracy in defining and localising intracranial targets and placing surgical tools. Brain shift can influence its accuracy significantly. Deep brain stimulation of the subthalamic nucleus can markedly change the quality of life of patients with advanced Parkinson's disease, but the outcome depends on the quality of electrode placement. ⋯ Deformation field analysis of pre- and postoperative three dimensional magnetic resonance images showed an intraoperative brain movement of 2 mm in the region of the subthalamic nucleus (the target point). Electrode repositioning resulted in efficient stimulation effects. This case report shows the need to reduce risk factors for intraoperative brain movement and demonstrates the ability of deformation field analysis to quantify this complication.
