The objective of this traffic safety investigation was to find critical road parameters affecting crash rate (CR). The study was based on crash and road maintenance data from Western Sweden. More than 3000 crashes, reported from 2000 to 2005 on median-separated roads, were collected and combined with road geometric and surface data. The statistical analysis(More)
Over the past four decades, techniques and devices for spinal cord stimulation have undergone considerable refinement. Currently, percutaneous implantable electrodes are placed in the epidural space and a low-frequency electrical current is used to modify the transmission of chronic pain signals in the dorsal columns of the spinal cord. Before permanent(More)
From January 1, 1986, to June 30, 1996, 240 patients were operated on for trigeminal neuralgia: 182 patients were treated by thermocoagulation of the gasserian ganglion after Sweet and 58 patients by decompression of the trigeminal nerve after Janetta. In the thermocoagulation group, followed up for 6 months to 10 years 95.2% of the cases showed freedom(More)
The preoperative and postperative follow-up EEG findings in 129 patients with intracranial meningiomas treated in the Department of Neurosurgery, University of Graz, are reported. In 87.6% of these cases there were EEG abnormalities. The EEG showed localized abnormalities which corresponded with the side of the lesion in 90 patients. Focal convulsion(More)
It is well known that crashes on horizontal curves are a cause for concern in all countries due to the frequency and severity of crashes at curves compared to road tangents. A recent study of crashes in western Sweden reported a higher rate of crashes in right curves than left curves. To further understand this result, this paper reports the results of(More)
Cerebral primitive neuro-ectodermal tumour (PNET) occurring as a second primary malignancy in childhood is exceedingly rare. We present a 7-year-old boy who developed a proven supratentorial PNET five years after enucleation and radio-/chemotherapy for a sporadic, unilateral retinoblastoma with optic nerve invasion. The association with this malignant eye(More)
For measuring and continuous recording of intracranial pressure a small telemetric pressure transducer, called "Teleceptor" was developed and energized by inductive energy transmission. Technical problems with regard to in vitro calibration stability, zero-point drift and tissue reaction were examined and discussed. Clinically the "Teleceptor" has so far(More)
