This article describes the professional lives of the founders of neurological surgery in Brazil as well as the Brazilian Society of Neurosurgery. The pioneers were Augusto Brandão Filho, the first general surgeon to perform brain surgery in Brazil, and José Ribe Portugal and Elyseu Paglioli, the founders of the first two neurosurgery schools in Brazil. The Brazilian Society of Neurosurgery was founded in Brussels, Belgium, on July 26, 1957, during the First International Congress of Neurological Surgery, at the initiative of José Ribe Portugal and José Geraldo Albernaz.

To determine the incidence of long-term hardware-related complications of deep brain stimulation (DBS). ⋯ Long-term follow-up reveals that hardware-related complications occur in a significant number of patients. Factors that lead to such complications must be identified and addressed to maximize the important benefits of DBS therapy.

Review Case Reports
Cerebellar hemorrhage after spinal surgery: report of two cases and literature review.
Cerebellar hemorrhage remote from the site of surgery may complicate neurosurgical procedures. We describe our experience with two cases of cerebellar hemorrhage after spinal surgery and review the three cases previously reported in the literature to determine whether these cases provide insight regarding the pathogenesis of remote cerebellar hemorrhage. ⋯ Cerebellar hemorrhage must be considered in patients with unexplained neurological deterioration after spinal surgery. Dural opening with loss of cerebrospinal fluid has occurred in every reported case of cerebellar hemorrhage complicating a spinal procedure, supporting the hypothesis that loss of cerebrospinal fluid is central to the pathogenesis of this condition. Because remote cerebellar hemorrhage can occur after procedures with the patient in the supine, sitting, and prone positions, patient positioning seems unlikely to play a causative role in its occurrence.

A prospective observational study was conducted to investigate whether episodes of ischemia are detected by continuous cerebral monitoring and whether such episodes are related to clinical outcome. ⋯ Intraparenchymal oximetry and microdialysis can detect but fail to predict the development of delayed cerebral ischemia. There were associations between episodes of low brain oxygen, abnormal microdialysis, and unfavorable outcome, but these associations were weak.

To study the association between the clinical examination and the radiological assessment of lumbar disc disease in patients with sciatica. ⋯ The positive correlation between disability status and imaging findings validates both assessment methods. Routine use of disability scores brings a useful contribution to the assessment of sciatica patients.
