-Objective: To determine the outcomes of 354 radiofrequency rhizotomies and 21 neuro v a s c ular decompressions perf o rmed as treatment for 367 facial pain patients (290 idiopathic trigeminal neuralgia, 52 symptomatic trigeminal neuralgia, 16 atypical facial pain, 9 post-herpetic neuralgia). M e t h o d : Clinical findings and surg e ry success rate were considered for evaluation. A scale of success rate was determined to classify patients, which considered pain relief and functional/sensorial deficits. Results: Radiofrequency rhizotomy was performed in 273 patients with idiopathic trigeminal neuralgia and in all other patients, except for trigeminal neuropathy; neurovascular decompression was perf o rmed in 18 idiopathic trigeminal neuralgia patients; 100% idiopathic trigeminal neuralgia, 96.2% symptomatic trigeminal neuralgia, 37.5% atypical facial pain and 88.9% post-herpetic neuralgia had pain re l i e f . Conclusion: Both t e c hniques for idiopathic trigeminal neuralgia are usefull. Radiofrequency rhizotomy was also efficient to tre a t symptomatic facial pain, and post-herpetic facial pain, but is not a good technique for atypical facial pain.KEY WORDS: facial pain, neurosurgery, trigeminal neuralgia, radiofrequency rhizotomy, vascular decompression.Rizotomia percutânea por radiofreqüência e a descompressão neurovascular do nervo trigêmeo no tratamento das algias faciais RESUMO -Objetivo: D e t e rminar eficácia e achados pós-operatórios após 354 rizotomias por radiofre q ü ê ncia e 21 descompressões neuro v a s c u l a res como tratamento de 367 pacientes com dor facial (290 neuralgia idiopática do trigêmeo, 52 neuralgia sintomática do trigêmeo, 16 dor facial atípica, 9 neuralgia pós-herp é t i c a ) . Método: Achados clínicos e taxa de sucesso das ciru rgias foram considerados para a avaliação. Uma escala avaliando alívio da dor e complicações sensoriais e funcionais foi utilizada para classificar os p a c i e n t e s . Resultados: A rizotomia por radiofreqüência foi realizada em 273 pacientes com neuralgia idiopática do trigêmeo e em todos os outros pacientes, exceto neuropatia trigeminal; descompressão neurovascular foi realizada em 18 pacientes com neuralgia idiopática do trigêmeo; 100% dos pacientes com neuralgia idiopática do trigêmeo, 96.2% dos pacientes com neuralgia sintomática, 37.5% dos pacientes com dor facial atípica e 88.9% dos doentes com neuralgia pós-herpética tiveram alívio da dor. C o n c l u s ã o : Ambas as técnicas são úteis para a neuralgia idiopática do trigêmeo. A rizotomia por radiofreqüência foi também eficiente para tratar neuralgia sintomática do trigêmeo e pós-herpética, mas não foi uma boa técnica como tratamento da dor facial atípica. PALAVRAS-CHAVE: dor facial, neurocirurgia funcional, neuralgia trigeminal, rizotomia por radiofreqüên-cia, descompressão neurovascular.

Men had markedly higher serum cTnI compared with women, although they were case matched with respect to age and cardiac risk factors. Our results may suggest there may be sex-related differences in the myocardial response to ischemia and reperfusion injury or intrinsic differences between the male and female myocardium.

Eleven cases of intracranial arterial aneurysms in patients under 15 years of age, treated from 1959 to 1976, are presented. The preponderance of aneurysms at the internal carotid artery bifurcation and the peculiarities of the defects in this location are remarkable.

We report two patients who presented with a dramatic recovery from severe sensorineural hearing loss after total surgical removal of cerebellopontine angle tumors (meningioma and jugular foramen neurinoma). The factors that differentiate these "non-acoustic tumors" in relation to the prognosis for hearing are discussed. A surgical approach that maintains the labyrinthine structure and preserves the arachnoid membrane of the superior cerebellopontine angle cistern during tumor removal is stressed.

The authors review the most important contributions of Pierre Marie to the elucidation and description of several neurological diseases, such as Charcot-Marie-Tooth’s disease and hereditary cerebellar ataxia, as well as his contributions to Internal Medicine, including his pioneering studies on acromegaly, ankylosing spondylitis, and hypertrophic pulmonary osteoarthropathy. His works led to incontestable advances in the medical sciences that transcended his time.
