Consensus on guidelines for stereotactic neurosurgery for psychiatric disorders
Background For patients with psychiatric illnesses remaining refractory to ‘standard’ therapies, neurosurgical procedures may be considered. Guidelines for safe and ethical conduct of such procedures have previously and independently been proposed by various local and regional expert groups. Methods To expand on these earlier documents, representative members of continental and international psychiatric and neurosurgical societies, joined efforts to further elaborate and adopt a pragmatic worldwide set of guidelines. These are intended to address a broad range of neuropsychiatric disorders, brain [...]

Convidamos vocês a participar da Neuromodulation Week, que acontecerá durante os dias 3 e 7 de agosto das 6 pm as 7 pm – horário de Brasília. Evento destinado a discussão e atualização em Neuromodulação. Inscrições pelo site neuromodulationweek.neurocirurgia.online Contamos com vocês
Anatomic Study of the Subthalamus
– OBJECTIVE: Subthalamic stimulation has become the procedure of choice in most cases of Parkinson’s Disease. This article describes subthalamic nucleus coordinates on human anatomical material, to infer the likely location of the target on the patient’s brain. – METHODS: The material consisted of 25 coronal brain slices stained using Mulligan’s method. A total of 40 subthalamic nuclei were identified and their dimensions were measured. The position of subthalamic nuclei related to the midline, cerebral cortex and red nucleus (RN) [...]
Outcome following lumbar disc surgery: the role of fibrosis
– BACKGROUND: Failed-back surgery syndrome remains a chal- lenge for spinal surgeons. It can be related to several causes, including poor surgical indication, misdiagnosis, surgical technique failure, spondilodiscitis and fibrosis. Fibrosis has been associated with a poorer outcome in lumbar disc surgery, although its role in the generation of symptoms is not yet clear. In this study, the authors have analyzed any possible correlation between the clinical outcome and the degree of fibrosis. – METHOD: Forty consecutive patients were enrolled [...]
Morphometric Analysis of the Nucleus Accumbens Using the Mulligan Staining Method
– BACKGROUND: There is a need to further anatomically describe the nucleus accumbens (NA), as there is a growing neurosurgical interest in this locus but a limited understanding of its structure. In this study, we evaluated quantitative NA parameters and spatial relationships with adjacent structures found in the telencephalon. – METHODS: A total of 155 NA specimens from coronal sections and 3 NA specimens from transverse sections were stained using the Mulligan technique as modified by Barnard et al. The [...]
Morphometric Study of the Internal Globus Pallidus Using the Robert, Barnard, and Brown Staining Method
– BACKGROUND: The globus pallidus internus (Gpi) is a major target in functional neurosurgery. Anatomical studies are crucial for correct planning and good surgical outcomes in this region. The present study described the anatomical coordinates of the Gpi and its relationship with other brain structures and compared the findings with those from previous anatomical studies. – METHODS: We obtained 35 coronal and 5 horizontal brain specimens from the Department of Anatomy and stained them using the Robert, Barnard, and Brown [...]
Cefaleia refratária com medicamentos-Tratamento com neuroestimulação periférica
Enquanto a maioria das dores de cabeça são causadas por tensão e não requerem intervenção médica , aproximadamente 20 % dos doentes possuemdores de cabeça incapacitantes e resistentes a tratamentos médicos. Exemplos desse tipo de dor são migrânea(enxaqueca), cefaleia em salvas e neuralgiaoccipital . Em 1999 , o jornal da sociedade internacional de neuromodulação chamado “Neuromodulation :tecnology at the neural interface ”publicou observações clínicas que descrevem o uso de neuroestimulação para reduzir dor de cabeça severa oriunda de neuralgia occipitalque [...]
Tratamentos para Enxaqueca Debilitante Continuam a Evoluir
Cerca de 12 em cada 100 pessoas experimentam ador de cabeça da enxaqueca em algum momento de suas vidas. Os sintomas diferenciais desse malforam descritos desde os tempos antigos. Enxaquecas sãodiferentes dasdores de cabeça tensionais mais comuns, que são causadas por tensão muscular nos ombros, pescoçoou couro cabeludo. Ataques de enxaqueca geralmente liberam uma dor pulsante em um dos lados da cabeçae que pode durar de quatro horas a váriosdias. Os sintomas da enxaqueca podem incluir alterações na visão, [...]
