ABSTRACT
The present study evaluated the calibers and anatomic configurations based on the Magnetic Resonance analysis (MRA), assaying the cerebral vascular territories and sex-linked variations. A randomized sample of 30 angiographic examinations in adult patients of both sexes was obtained and components of the circle of Willis were identified. Branch diameters were measured on a transversal cut 5mm from the vessel origin in a typical angiographic frontal incidence. For the comparative statistical analysis, tests were divided in the groups considering the patients' sex and age. The classical Circle of Willis configuration was oberved in only 15 samples (50%). Greater calibers were observed in the arteries of the posterior circulation and multiple linear regression analysis established that the caliber of the posterior circulation was influenced by an independent variable related to the gender. Additional variations included unilateral and bilateral fetal and hypoplasic Posterior communicating arteries. In the anterior cerebral artery (ACA), the presence of an accessory developed ACA, an ACA giving branches to the distal portion of the two hemispheres and a third median ACA the variants were observed. Gender influenced the variations on internal diameters of posterior circulation vessels, with larger measurements in men.
ABSTRACT
A hanseníase é uma doença infecto-contagiosa, que além de alterações dermatológicas, possui manifestações neurológicas. Relatamos o caso de um homem de 66 anos, que apresentou nevralgia do trigêmeo após ter apresentado quadro de hanseníase.
Hansen's disease is an infectious disease that presents with skin changes, as well as neurological features. We report a case of a 66 years man, who presented with trigeminal neuralgia after developing Hansen's disease.

O angioedema é uma reação inflamatória local potencialmente grave. Estudos evidenciam uma incidência destes casos após uso de alteplase entre 0,02% e 5,1%. Relatamos um caso de acidente vascular cerebral isquêmico agudo tratado com alteplase que evoluiu com angioedema e piora clínica. Este paciente teve expressiva melhora neurológica com posterior declínio clínico após o angioedema. O mecanismo inflamatório neste caso pode ter desempenhado papel determinante na reoclusão.
Angioedema is a potentially severe local inflammatory reaction. There is an incidence of 0.02% to 5.1% in patients treated with alteplase. We report a case of acute ischemic stroke that was treated with alteplase and presented a life threatening allergic reaction. This patient had an important neurologic improvement in the beginning, but this benefit was lost after angioedema. The inflammatory mechanism that causes angioedema is sometimes decisive in re-occlusion.

Uma grande proporçäo de pacientes que sofreram traumatismo crânio-encefálico (TCE) desenvolve crises compulsivas após o trauma, as quais podem se repetir muitas vezes ao longo do tempo, transformando a qualidade de vida do doente. No presente artigo é feita uma revisäo na literatura médica a respeito da Eplepsia Pós-traumática (EPT), sua apresentaçäo clínica, sua fisiopatogenia, seu tratametno, sua profilaxia e seu prognóstico

Foram estudadas as artérias órbito-frontal e pré-frontal em 50 encéfalos humanos, empregando-se resina de Batson, com a finalidade de estabelecer a possível utilizaçäo destas artérias como receptoras nas técnicas de revascularizaçäo cortical. As artérias pré-frontais mais freqüentemente (88% à direita e 86% à esquerda) tinham diâmetro e extensäo superficial compatíveis com sua utilizaçäo
