Reabilitação no Acidente Vascular Cerebral: do Hospital à Comunidade

The field of action for rehabilitation is that of making use of the patient's maximum functional capacity with the purpose of adapting to life in relation to the environment. Rehabilitation must commence immediately, although it may be in different forms from the acute phase to sequelae. It is considered appropriate to call the physiatrist as soon as the neurologic condition has stabilised. A list is made of the measures to be taken for rehabilitation in the acute phase and sequelae, and the composition of the rehabilitation team is described. In what concerns location, where to rehabilitate the patient? The group of ambulatory patients should have their rehabilitation as outpatients. Our experience with house calls is briefly described. The group of patients who cannot walk, those that present an eminently motor condition, with the possibility of being able to walk, should be with their families, with transport provided to health and rehabilitation centres. The second group, with the capacity of walking within a reasonable time, especially if with multiple associated problems such as impaired communication, should be hospitalised in a rehabilitation department. The third group consists of severely handicapped patients, for whom a solution must be found that provides life with a minimum of dignity in centres or homes. From among the measures to be introduced, we point out following: acquisition of transport for patients who must travel, as outpatients, to the department; providing family doctors with complete freedom to refer their patients to rehabilitation centres.

Cerebral aspergillosis due to Aspergillus fumigatus in AIDS patient: first culture - proven case reported in Brazil

Cerebral aspergillosis is a rare cause of brain expansive lesion in AIDS patients. We report the first culture-proven case of brain abscess due to Aspergillus fumigatus in a Brazilian AIDS patient. The patient, a 26 year-old male with human immunodeficiency virus (HIV) infection and history of pulmonary tuberculosis and cerebral toxoplasmosis, had fever, cough, dyspnea, and two episodes of seizures. The brain computerized tomography (CT) showed a bi-parietal and parasagittal hypodense lesion with peripheral enhancement, and significant mass effect. There was started anti-Toxoplasma treatment. Three weeks later, the patient presented mental confusion, and a new brain CT evidenced increase in the lesion. He underwent brain biopsy, draining 10 mL of purulent material. The direct mycological examination revealed septated and hyaline hyphae. There was started amphotericin B deoxycholate. The culture of the material demonstrated presence of the Aspergillus fumigatus. The following two months, the patient was submitted to three surgeries, with insertion of drainage catheter and administration of amphotericin B intralesional. Three months after hospital admission, his neurological condition suffered discrete changes. However, he died due to intrahospital pneumonia. Brain abscess caused by Aspergillus fumigatus must be considered in the differential diagnosis of the brain expansive lesions in AIDS patients in Brazil.

Aspectos Imagiológicos da Trombose Venosa Cerebral numa Mulher Grávida

A trombose venosa cerebral (TVC) é uma doença relativamente rara mas grave, potencialmente reversível com diagnóstico atempado e terapêutica médica adequada. A gravidez e o puerpério são um factor predisponente de TVC, que é responsável por 6% das causas de morte materna. As manifestações clínicas dependem da localização, extensão do trombo, bem como da rede de colaterais existente. Apresentamos o caso duma doente do sexo feminino, 33 anos, grávida de 13 semanas que recorreu ao serviço de urgência por quadro de cefaleias e cujo estudo por Ressonância Magnética revelou aspectos compatíveis com doença venosa oclusiva subtotal do seio longitudinal superior em fase aguda. A propósito deste caso discutimos as manifestações imagiológicas da trombose venosa dural na fase aguda.

Protecção Cerebral na Cirurgia do Arco Aórtico

In this paper the authors proceed to a revision of the three main methods employed for cerebral protection in aortic arch surgery, namely the deep hypothermia and total circulatory arrest, the retrograde cerebral perfusion and the selective anterograde cerebral perfusion. After a deep analysis on their advantages and disadvantages, they proposed the utilization of an association of methods (integrated approach) that has proved to be extremely well succeed in their clinical practice, specially in high-risks patients.

Rotavirus serotypes and electropherotypes identified among hospitalised children in São Luís, Maranhão, Brazil

During June 1997-June 1999 rotavirus infection was screened in infants aged up to 2 years and hospitalised with acute diarrhoea in São Luís, Northeastern Brazil. Altogether, 128 stool samples were collected from diarrhoeic patients and additional 122 faecal specimens from age- and- temporal matched inpatients without diarrhoea were obtained; rotavirus positivity rates for these groups were 32.0% (41/128) and 9.8% (12/122), respectively (p < 0.001). Both electropherotyping and serotyping could be performed in 42 (79.2%) of the 53 rotavirus-positive stool samples. Long and short electropherotypes were detected at similar rates - 38.1% and 40.5% of specimens, respectively. Overall, a G serotype could be assigned for 35 (83.3%) of specimens, the majority of them (66.7%) bearing G1-serotype specificity. Taking both electropherotypes and serotypes together, G1 rotavirus strains displaying long and short RNA patterns accounted for 30.9% and 19.0% of tested specimens, respectively; all G2 strains had short electropherotype. Rotavirus gastroenteritis was detected year-round and, in 1998, the incidence rates tended to be higher during the second semester than in the first semester: 45.2% and 26.1% (p = 0.13), respectively. Rotavirus infections peaked at the second semester of life with frequencies of 30.1% and 13.5% for diarrhoeic children and controls, respectively. While the six rotavirus strains bearing G2-type specificity were circulating throughout the whole study period, G1 serotypes (n = 27) emerged as from June 1998 onwards, 20 (74.1%) of which clustering in 1998. These data underscore the importance of rotaviruses in the aetiology of severe infantile gastroenteritis in Northeastern Brazil and sustain the concept that a future vaccine should confer protection against more than one serotype.
