Stereotaxic surgery is becoming increasingly important because of the possibility of approaching the deep zones of the brain with less risk. It is in daily use in cerebral tumours and in the functional surgery of Parkinson's disease. The use of antibiotic prophylaxis in neurosurgery is controversial, although in many centres, including ours, all patients receive it. ⋯ These results support the hypothesis of use of antibiotic prophylaxis in stereotaxic surgery to achieve a reduction in intra-hospital infections in surgical patients.

Case Reports[Delayed central pain associated with a sub-insular hematoma followed by parieto-occipital tumor. Favorable effects of chronic stimulation of the ventral posterior thalamic nucleus].
Déjerine and Roussy reported thalamic syndrome, chronic pain after a vascular lesion in the thalamus, in 1906. Posterior clinical observations allowed know that the same clinical picture can be observed after lesions in other parts of the central nervous system. Due to the fact that the more frequent etiology is vascular, nowadays the term central poststroke pain syndrome is preferred. ⋯ The lancinating pain and the allodynia were properly controlled by deep brain stimulation with an electrode placed stereotactically at the level of VPL nucleus of the left thalamus. Five months later there was a recurrence of the pain, a CT disclosed a tumour in the parietal region with an important shift of the midline and migration of the electrode out the thalamus. A biopsy disclosed tumoral necrosis. The pathophysiology of the central poststroke pain and effectivity of the deep brain stimulation in this cases are discussed.
