Spinal epidural empyemas.
Evangelista, T; Pimentel, J; Antunes, J LWe report ten patients harbouring spinal epidural abscess, aiming to evaluate the factors that may lead to an early diagnosis and that can eventually influence the prognosis. There were seven males and 3 females, with ages comprised between 17 and 66 years. Abscesses were localised mainly in the dorsal region. The most important predisposing factors were infections or other disorders know to be related with com...
A diaphragmatic pacemaker in the treatment of ventilatory failure.
Ponce, P; Cruz, J; Travassos, J; Moreira, P; Lima, J A; Pedro, A G; Ferreira, A C; Antunes, J LDiaphragmatic Pacing was used to treat ventilatory failure in a young boy with bilateral diaphragmatic palsy secondary to cervical cord injury, on chronic mechanical ventilation for 6 months. The indications for diaphragmatic pacing in ventilatory failure were discussed, as well as the assessment of phrenic nerve integrity and the pacing schedules utilized to slowly improve the diaphragm endurance and achieve a...
Aneurysmal bone cysts of the spinal canal.
Albuquerque, L; Pimentel, J; Távora, L; Antunes, J L; Ferreira, A G; Campos, JAneurysmal bone cysts (ABC) are rare bone tumors of controversial pathogenesis. In 15% of cases, they are localized in the vertebrae. Despite the absence of anaplasia, their volume and localization are often responsible for incomplete surgical resection. The authors present 5 cases of primary vertebral ABC, 4 females and one male, localized in cervical (3 cases), dorsal (1 case) and lumbar (1 case) spine. Sympt...
Errors in medicine.
Antunes, J LThe author discusses the different kinds of errors that may be committed in clinical practice. The socioeconomic and professional factors that make doctors particularly vulnerable are briefly reviewed.; The author discusses the different kinds of errors that may be committed in clinical practice.

Decision making in patients with subarachnoid hemorrhage.
Antunes, J LDiagnostic and therapeutic management options in cases of subarachnoid hemorrhage secondary to aneurysm rupture are discussed. Particular emphasis is given to the diagnosis, medical treatment and timing of surgery. The problems raised by the presence of an intracerebral hematoma, acute hydrocephalus and multiple aneurysms are reviewed. The author also discusses the management of incidental aneurysms, partially ...
Spinal cord tumors. Anatomoclinical study.
Pereirinha, R; Pimentel, J; Antunes, J LThe authors review 36 cases of intramedullary spinal tumours, 17 ependymomas, 12 astrocytomas, 6 hemangioblastomas and 1 metastasis of leiomyosarcoma. The tumours were localized in the cervical region in 19 patients, in the thoracic region in 10 in the lumbar region in 4, and in the conus medullaris in 3. All patients presented a clinical picture of myelopathy. No differences were observed between the different...
Neuroradiology in the physiopathologic diagnosis of subarachnoid hemorrhage--ce...
Campos, J G; Gomes, L B; Almeida, A; Fernandes, A; Coutinho, D; Afonso, J G; Ferro, J; Trindade, A; Antunes, J LThe clinical importance of the cerebral aneurismatic lesion in well known. In Portugal we still do not have reliable statistics regarding the occurrence of the subarachnoid hemorrhage, however we can make a comparison through Kassel's and Drake's studies where they refer that annually 28,000 North-Americans suffer from subarachnoid hemorrhage attributed to the rupture of the cerebral aneurysm. This is a clinica...
Perimesencephalic hemorrhage.
Canhão, P; Pinto, A N; Pinho e Melo, T; Ferro, J M; Campos, J G; Trindade, A M; Antunes, J LAmong 293 subarachnoid hemorrhages admitted to the Neurology and Neurosurgery departments of Sta Maria Hospital, 108 patients had a normal cerebral angiography. Twenty-three meet the radiological criteria for perimesencephalic hemorrhage (center of the hemorrhage located in front of the mesencephalon, without blood in the interhemispheric and lateral sylvian fissures, nor significant intraventricular hemorrhage...
Nimodipine in subarachnoid hemorrhage.
Ferro, J M; Canhão, P; Melo, T P; Campos, J G; Trindade, A; Antunes, J LThe efficacy of nimodipine in decreasing mortality and morbidity of subarachnoid haemorrhage (HSA) is evaluated in 51 patients admitted to the Neurological and Neurosurgery Departments of the Santa Maria Hospital. Reductions of 2 x (0.65, 6.39) of the incidence of ischemia in the total group and of 2.1 x (0.58, 7.79) of mortality in the sub-group with initial severity of less than 4 points of the Hunt score wer...
Embolotherapy in aneurysm of the basilar artery.
