Moyamoya disease. Report of three cases in Brazilian patients.

Moyamoya disease (MMD) is a chronic occlusive cerebrovascular disease of unknown etiology reported mainly in the Japanese. Most cases occur in children. The disease is rare in non-Oriental adults manifesting itself mostly as intracerebral hemorrhages. We describe MMD in 2 non-Oriental young adults and one adolescent that developed cerebral infarctions. The adults were medicated with aspirin and no medication was given to the adolescent. All patients did not deteriorate in a follow-up period from 1 to 4 years. Although rare, MMD is an important cause of stroke in young individuals and may well be underreported: only 18 patients have been reported till 1997 in Brazil. Neurologists should include MMD in differential diagnosis of ischemic and hemorrhagic strokes in young adults.

[Basilar ectasia and stroke: clinical aspects of 21 cases].

Ectasia of the basilar artery (EB) occurs when its diameter is greater than normal along all or part of its course, and/or when it is abnormally tortuous. EB may cause cranial nerve dysfunction, ischemic stroke or subarachnoid hemorrhage, pseudotumor or hydrocephalus. We tried to describe cases of stroke associated with EB, analyze its frequency, clinical aspects, and the mechanisms involved in different forms of its presentation. We found 21 patients with stroke and EB. The association between EB and stroke was more prevalent in males over the age of fifty. Main symptoms were hemiparesia, cranial nerves dysfunction, and cerebellar ataxia. Cerebral infarcts associated with EB were due to different mechanisms: arterial thrombosis, artery-to-artery embolism, mass effect with angulation and obstruction of the vertebral and basilar branches.

[Basilar ectasia and stroke: imaging features in 21 cases].

Ectasia of the basilar artery (EB) may cause different clinical manifestations, and its analysis by imaging methods is fundamental. We tried to analyse radiological aspects in 21 patients with stroke and EB. In all of them, diagnosis could be done by computed tomography. However, magnetic resonance was the most complete diagnostic method for the evaluation of the relationship between EB an surrounding structures.

[Socioeconomic characteristics of patients with stroke].

We studied the socioeconomic status of 206 stroke patients seen at Escola Paulista de Medicina--São Paulo in the period of 1991-1992. We found that 25% of patients were less than 50 years old; men were married significantly more often than women; 82% of patients had less than 8 years of formal education and 60% of the families survived with US$ 98 to 198. The socioeconomic impact caused by a stroke is very important. Low education and poverty influence the treatment and prevention of the disease. The Social Assistance Service can detect and attempt to solve the social problems in order to obtain a better control of systemic diseases and risk factors for stroke, and to give orientation concerning the local resources.
