BACKGROUND Neurostimulation of the subthalamic nucleus reduces levodopa-related motor complications in advanced Parkinson's disease. We compared this treatment plus medication with medical management. METHODS In this randomized-pairs trial, we enrolled 156 patients with advanced Parkinson's disease and severe motor symptoms. The primary end points were(More)
Serious adverse events (SAEs) during the first 30 postoperative days after stereotactic surgery for Deep-Brain-Stimulation performed in 1,183 patients were retrospectively collected from five German stereotactic centers. The mortality rate was 0.4% and causes for death were pneumonia, pulmonary embolism, hepatopathy, and a case of complicated multiple(More)
The results of deep brain stimulation (DBS) of the globus pallidus internus (Gpi) in six patients with generalized, focal, and segmental dystonia are presented. Pre- and postoperative assessments are given for one patient with generalized inherited dystonia and for five patients with idiopathic segmental or cervical dystonia. Clinical symptoms were(More)
Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) is a primary head-pain syndrome, which is often refractory to any medical treatment. Concerning the pathophysiology of SUNCT, hypothalamic involvement ipsilaterally to the pain has been suggested based on the clinical features and one functional imaging case(More)
It has been repeatedly demonstrated that the movements of patients with Parkinson's disease (PD) are less impaired when external timing cues are provided. This suggests that the basal ganglia, which are impaired in PD, are less involved in the control of externally timed movements. In the present study, we tested this hypothesis by contrasting the effect of(More)
BACKGROUND Deep brain stimulation (DBS) of the globus pallidus internus (GPi) offers a very promising therapy for medically intractable dystonia. However, little is known about the long-term benefit and safety of this procedure. We therefore performed a retrospective long-term analysis of 18 patients (age 12-78 years) suffering from primary generalized (9),(More)
Appropriate treatment for intracranial mass lesions depends upon accurate morphological diagnosis. In 47 of 360 patients the findings in stereotactically obtained tissue cylinders were compared with tumor resection (n=38) or autopsy (n=9) tissue material to define the accuracy of our stereotactic biopsy method. These biopsies were performed using the(More)
OBJECT The authors prospectively evaluated the therapeutic effect of computerized tomography (CT)-guided kryorhizotomy in the treatment of patients with lumbar facet joint syndrome (LFJS) and assessed prognostic factors that predict this effect. METHODS Between February 2001 and March 2004, CT-guided kryorhizotomy of facet joints was performed in 76(More)
Over two decades ago, the electrostimulation of the trigeminal ganglion (TGES) was established as a treatment option for patients with trigeminopathic pain due to a (iatrogenic) lesion of the trigeminal nerve, on whom the other therapeutic methods, either neurosurgical or conservative have very limited efficacy and usually are associated with a poor(More)
In establishing the histological diagnosis of primary cerebral lymphoma, stereotactic brain tumour biopsy is the method of choice as the mainstay of therapy is radiation and chemotherapy. This study describes the histopathology and diagnostic immunohistochemistry of 54 primary brain lymphomas in a mainly non-AIDS population. The stereotactic biopsies were(More)
