- ItemAcesso aberto (Open Access)Características das crises epilépticas após acidente vascular cerebral isquêmico(Academia Brasileira de Neurologia - ABNEURO, 1997-01-01) Fukujima, Marcia Maiumi [UNIFESP]; Cardeal, Jose Osmar [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Cerebral infarctions are one of the most important causes of late onset epilepsy. We have studied 35 patients who presented epileptic seizures after ischemic stroke. All of them had the first seizure at least 24 hours after the stroke, and they had at least one recurrence of seizure. The objective was to determine the main characteristics of these seizures and to correlate them to clinical and laboratorial findings. The interval between the stroke and the first seizure was 3 to 1650 days. Late onset seizures (>14 days) were present in 89%, they occurred predominantly 6 to 12 months after stroke. Partial seizures (31/35) were more frequent than generalized ones. Status epilepticus occurred in only 3 cases. Most of the patients (30/35) had occasional seizures (<, 1 seizure monthly). There were no association between seizure type and the time interval between the stroke and the first seizure, neither with the seizure frequency. The most frequent EEG finding was focal slowing oi cerebral activity. Pharmacological control was easily obtained. No patient needed more than one drug for seizure control.
- ItemAcesso aberto (Open Access)Estudo de fatores clínicos preditivos para crises epilépticas após acidente vascular cerebral isquêmico(Academia Brasileira de Neurologia - ABNEURO, 1996-06-01) Fukujima, Marcia Maiumi [UNIFESP]; Cardeal, Jose Osmar [UNIFESP]; Lima, Jose Geraldo de Camargo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Preditive clinical factors for epileptic seizures after ischemic stroke. Clinical features of 35 patients with ischemic stroke who developed epilepsy (Group 1) were compared with those of 35 patients with ischemic stroke without epilepsy (Group 2). The age of the patients did not differ between the groups. There were more men than women and more white than other races in both groups. Diabetes melitus, hypertension, transient ischemic attack, previous stroke, migraine, Chagas disease, cerebral embolism of cardiac origin and use of oral contraceptive did not differ between the groups. Smokers and alcohol users were more frequent in Group 1 (p<0,05). Most patients of Group 1 presented with hemiparesis; none presented cerebellar or brainstem involvement. Perhaps strokes in smokers have some different aspects, that let them more epileptogenic than in non smokers.
- ItemAcesso aberto (Open Access)Exames subsidiários preditivos de crises epilépticas após acidente vascular cerebral isquêmico(Academia Brasileira de Neurologia - ABNEURO, 1997-01-01) Fukujima, Marcia Maiumi [UNIFESP]; Cardeal, Jose Osmar [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)We studied subsidiary laboratorial tests such as serum glucose, red blood cell count, total cholesterol, HDL and LDL cholesterol and triglycerides, eletrocardiogram, eletroencephalogram (EEG), cerebrospinal fluid, and CT scan of 35 patients with cerebral infarction who developed epileptic seizures (group 1 or G1), and compared them to a group of 35 patients who had cerebral infarction but have not developed epileptic seizures (group 2 or G2). The EEG analysis showed significance in the comparison between the groups; focal lentification of the electrical cerebral activity was the most frequent abnormality found in G1. Extensive infarcts were also more frequent in G1. The association of abnormal EEG and extensive lesion on CT may be considered a preditive factor for occurrence of epileptic seizures after cerebral infarction. The analysis of the other tests showed no significance on the comparison between the groups.
- ItemAcesso aberto (Open Access)Gravidez, puerpério e doença vascular cerebral(Academia Brasileira de Neurologia - ABNEURO, 1996-06-01) Fukujima, Marcia Maiumi [UNIFESP]; Oliveira, Roberto De Magalhães Carneiro de [UNIFESP]; Shimazaki, Jean Carlos [UNIFESP]; Lima, José Geraldo de Camargo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Six patients who presented cerebrovascular disease during puerperium or pregnancy were studied. One of them presented hemorrhagic stroke caused by intracerebral bleeding due to pre-eclampsia. Three patients presented ischemic stroke, they all had positive serologic reactions for Chagas' disease, but only two of them had clinical cardiopathy; one of these patients had anticardiolipin antibody. The other two patients presented cerebral venous thrombosis of sagittal sinus. Both were smokers and one of them used oral contraceptive. We emphasize the importance of clinical investigation to seek for the common causes of cerebrovascular disease in young people, with special attention to Chagas disease in Brazil.
- ItemAcesso aberto (Open Access)Malaria and stroke: case report(Academia Brasileira de Neurologia - ABNEURO, 1999-12-01) Leopoldino, JosÉ FÁbio Santos [UNIFESP]; Fukujima, Marcia Maiumi [UNIFESP]; Gabbai, Alberto Alain [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Malaria is a parasitic disease with high prevalence in several regions of the world. Infestation by Plasmodium faciparum can, in some cases, affect the central nervous system producing encephalitis resulting in death or neurological sequelae. The mechanisms involved in the pathophysiology of the cerebral lesion are not totally clear and there are currently two theories (mechanical and humoral) concerning this. We report a case of malaria with an atypical evolution, with a stroke lesion in the territory of the middle cerebral artery, with no association with encephalitis. We conclude that the mechanical theory is the one applicable to this patient.
