Trombose de seio dural: relato de caso

We report the case of a 24 year-old pregnant woman, seem at the neurology service by presenting agitation, hallucinations, mental confusion, headache, vision loss, aphasia and seizures. the neurorradiologic exam was compatible with thrombosis in dural sinus and cortical veins. Treatment with abciximab was accomplished and the mechanical lysis of the thrombus was made obtaining restoration of cerebral vein flow. After the procedure, she presented frontal hematoma wich was withdrawn surgically. We discuss this infrequent pathology in clinical picture, pathogenesis, image exams and therapeutics.Univ Caixas Sul, Disciplina Neurol, Caixas Do Sul, RS, BrazilUniversidade Federal de São Paulo, Escola Paulista Med, São Paulo, BrazilUniv Caxias do Sul, Curso Med, Caxias Do Sul, RS, BrazilUniversidade Federal de São Paulo, Escola Paulista Med, São Paulo, BrazilWeb of Scienc

Avulsão medular torácica sem anormalidades radiológicas: relato de caso

Spinal cord injury without radiologic abnormalities is a rare condition that occurs more frequently in children and contributes to a high rate of morbidity among these patients. We report the case of a five-month-old infant, victim of automobile accident, who was brought to our service with a sensitive level in T2 and bilateral crural paraplegia. Radiographic exams and computed tomography of spine did not evidence of bone or ligaments injuries. Magnetic resonance image showed complete spinal cord transection and spine avulsion in the segment between T3 and T7. We discuss this pathology according to its epidemiology, pathophysiology, diagnosis, treatment and prognostic aspects.Univ Caxias Sul, Disciplina Neurol, Caxias Do Sul, RS, BrazilUniversidade Federal de São Paulo, Escola Paulista Med, São Paulo, BrazilUniv Caxias Sul, Acad Curso Med, Caxias Do Sul, RS, BrazilUniversidade Federal de São Paulo, Escola Paulista Med, São Paulo, BrazilWeb of Scienc

Twelve Years of Scientific Production on Medline by Latin American Spine Surgeons

Background: Despite the small contribution of LA in the Science Citation Index (SCI), a growing contribution by LA research to international literature has been observed in recent years.Study Design: Systematic review.Purpose: To evaluate the scientific contribution of Latin American (LA) Spine Surgeons in the last decade.Methods: A literature search of publications by LA spinal surgeons on topics concerning the spine or spinal cord was performed using an online database; Pubmed.gov. the results were limited to articles published from January 2000 to December 2011. the quality of the publication was evaluated with the journal impact factor (IF), Oxford classification and number of citations.Results: This study comprised 320 articles published in the Medline database by LA spine surgeons from 2000 to 2011. in recent years, there has been an increase in the number of publications by LA spine surgeons. It was observed that 38.4% of LA papers were published in LA journals. 46.6% of the articles were published in journals with an IF lower than 1, and there was no statistically significant difference in the number of articles published in journals with a higher IF during the period. Linear-by-linear association analysis demonstrated an improvement in the level of evidence provided by LA articles published in recent years.Conclusions: This study showed a growth in the number of publications in last 12 years by LA spinal surgeons. It is necessary to discuss a way to increase quantity and quality of scientific publications, mainly through a better education in research.AOSpine Latin AmericaUniv Caxias do Sul, Dept Neurosurg, Caxias Do Sul, RS, BrazilHosp Servidor Publ Estadual Francisco Morato de O, Dept Neurosurg, São Paulo, BrazilHosp Sao Jose Santa Casa Porto Alegre, Dept Neurosurg, Porto Alegre, RS, BrazilUniversidade Federal de São Paulo, Dept Orthoped, São Paulo, BrazilHosp Univ Fdn Favaloro, Dept Orthoped, Buenos Aires, DF, ArgentinaUniv Desarrollo, Dept Orthoped, Santiago de Compostela, SpainCtr Med Nacl Occidente, Dept Orthoped, Guadalajara, Jalisco, MexicoUniv São Paulo, Dept Orthoped, São Paulo, BrazilUniversidade Federal de São Paulo, Dept Orthoped, São Paulo, BrazilWeb of Scienc

Paralisia de Bell: fisiopatologia e tratamento = Bell’s palsy: physiopathology and treatment

Objetivos: revisar a literatura sobre os aspectos clínicos, fisiopatológicos e terapêuticos da paralisia de Bell. Fonte de dados: revisão dos artigos indexados nas bases de dados Medline e Scielo. Os termos utilizados foram paralisia de Bell, epidemiologia, etiologia, Herpes simplex e tratamento. Síntese dos dados: alguns estudos demonstraram associação da paralisia de Bell com a infecção pelo vírus Herpes simplex. Fatores climáticos podem atuar como reativadores da infecção latente desse vírus no gânglio geniculado do nervo facial, causando o aparecimento da paralisia. O diagnóstico da paralisia de Bell é essencialmente clínico, afastando-se outras causas de paralisia facial periférica. Conclusões: a fisiopatologia da paralisia de Bell ainda permanece não bem esclarecida, embora tenha sido demonstrada associação com a presença do vírus Herpes simplex. O seu tratamento permanece controverso, no entanto recentes ensaios clínicos bem conduzidos confirmam o benefício dos corticosteróide
