Subthalamic deep brain stimulation versus best medical treatment: a 12-year follow-up.

Purpose: Electrical stimulation of the sub-thalamic nucleus (STN-DBS) is well established to alleviate motor fluctuations in advanced Parkinson's disease but little is known about its very long-term efficacy.

Methods: We followed over 12 years 15 parkinsonian patients having undergone STN-DBS and compared them to a matched group of 14 patients with best medical drug therapy. All had been considered as good candidates for surgery.

Reversible tonsillar prolapse and syringomyelia after embolization of a tectal arteriovenous malformation. Case report and review of the literature.

The authors report the case of a 21-year-old woman who presented with headaches, frequent sensations of loss of equilibrium, and intermittent strabismus. A tectal arteriovenous malformation (AVM) was diagnosed based on magnetic resonance (MR) imaging findings. The AVM drained toward the straight sinus and was associated with a tonsillar prolapse (Chiari malformation Type I [CM-I]) and cervical syringomyelia.

Case Report: A 15-year-old boy was admitted to the hospital because of symptoms related to acute intracranial hypertension (headache and vomiting).
