[Profile of effective donors from organ and tissue procurement services]. / Perfil de doadores efetivos do serviço de procura de órgãos e tecidos.

OBJECTIVE: To characterize the profile of effective organ and tissue donors and to understand which organs and tissues were donated for transplantation. METHODS: This was a quantitative, descriptive, exploratory, retrospective study that analyzed clinical data from 305 donors between January 2006 to December 2010. The data were then analyzed using descriptive analyses, generating frequency tables, measures of position (mean, minimum and maximum) and measures of dispersion (standard deviation) for data that was social and clinical in nature. RESULTS: There was an overall predominance of white (72%) and male (55%) individuals between the ages of 41 and 60 years (44%). The primary cause of brain death was cerebrovascular accident (55%). In the patient history, 31% of the patients were classified as overweight, 27% as hypertensive and only 4.3% as having diabetes mellitus. Vasoactive drugs were used in 92.7% of the donors, and the main drug of choice was noradrenaline (81.6%). Hyperglycemia and hypernatremia were diagnosed in 78% and 71% of the donors, respectively. CONCLUSION: Significant hemodynamic changes were found, and the results indicate that the use of vasoactive drugs was the main strategy used to control these changes. Furthermore, most donors presented with hyperglycemia and hypernatremia, which were frequently reported in association with brain death. The persistent nature of these findings suggests that the organ donors were inadequately maintained.

Perfil de doadores efetivos do serviço de procura de órgãos e tecidos / Profile of effective donors from organ and tissue procurement services

Objetivo: Caracterizar o perfil dos doadores efetivos de órgãos e tecidos além de conhecer quais órgãos e tecidos foram doados para transplantes. Métodos: Estudo quantitativo, descritivo, exploratório e retrospectivo, analisando-se os dados de prontuários de 305 doadores, entre janeiro de 2006 a dezembro de 2010, os quais foram submetidos à análise descritiva com confecção de tabelas de frequência, medidas de posição (média, mínimo e máximo) e dispersão (desvio-padrão) para os dados de caráter social e clínico. Resultados: Houve predomínio de indivíduos brancos (72%), do gênero masculino (55%), idade entre 41 e 60 anos (44%), sendo a principal causa de morte encefálica o acidente vascular encefálico (55%). Quanto aos antecedentes, 31% foram classificados na categoria de sobrepeso, seguidos de hipertensão arterial sistêmica (27%) e o diabetes mellitus encontrado em apenas 4,3% dos doadores. O uso de drogas vasoativas esteve presente em 92,7% dos doadores, e a principal droga utilizada foi a noradrenalina (81,6%). A hiperglicemia e a hipernatremia foram encontradas em 78% e em 71% dos doadores, respectivamente. Conclusão: Foram encontradas importantes alterações hemodinâmicas, e os resultados mostram o uso de drogas vasoativas como a principal estratégia para seu controle. Ademais, a maioria dos doadores apresentou hiperglicemia e hipernatremia, achados frequentes no quadro de morte encefálica, e que, por sua persistência, sugerem manutenção inadequada do doador de órgãos. .

Tratamento cirúrgico das metástases cerebrais / Surgical Treatment of Brain Metastases

As metástases cerebrais são complicações comuns do câncer sistêmico, sendo os tumores intracranianos mais freqüentes e com incidência crescente. Os autores discutem algumas característicasepidemiológicas e as novas técnicas neurocirúrgicas como modalidade terapêutica, enfatizando seus resultados, independentemente da proximidade das lesões com áreas eloqüentescerebrais.

Benefícios da hemisferectomia em pacientes com hemimegalencefalia / Hemispherectomy of hemimegalencephaly

A hemisferectomia é realizada em muitos casos de hemimegalencefalia para controlar a epilepsia refratária ao tratamento medicamentoso. No entanto, apesar de haver concordância sobre a efetividade desse procedimento para controle das crises, a escolha da técnica cirúrgica utilizada ainda é motivo de debate. Relatamos os casos de três crianças com hemimegalencefalia submetidas à hemisferectomia para tratamento de suas crises refratárias: uma foi submetida à hemisferectomia anatômica e as outras duas, à hemisferectomia funcional. Os resultados confirmam a efetividade da hemisferectomia para o controle das crises epilépticas nesses casos.

Trombose da artéria carótida interna devida a trauma penetrante no pálato mole: relato de caso / Thrombosis of the internal artery secondary to soft palate injury: case report

Descrevemos caso de trauma penetrante na região oral em criança, evoluindo com oclusão da arteria carótida interna e déficit neurológico correspondente. A tomografia computadorizada e a ressonância nuclear magnética demonstram a oclusão completa da artéria carótida interna. Enfatizamos esta rara complicação de trauma oral, comum em crianças e discutimos os aspectos patogênicos.

Arachnoid cyst: adversity and plasticity

We report four cases of surgically treated intracranial arachnoid cysts, one with cyst-peritoneal shunt and three with craniotomy and arachnoid membrane resection. Their classification and etiopathogeny are discussed, and especially the different methods of treatment comparing the drastic complications (adversities) with the favorable solutions in severe clinical cases (plasticity) treated at our institution.
