Abstract: subclavian steal syndrome refers to the association of neurological symptoms related to vertebrobasilar insufficiency and the phenomenon of subclavian steal. we report the case of a 63 year-old male patient that presented subclavian steal syndrome and severe proximal (80%) stenosis of the left subclavian artery. the patient was submitted to percutaneous transluminal angioplasty and stenting on the left sa. the procedure was well tolerated and immediately afterwards, there was complete remission of the symptoms and of the phenomenon of subclavian steal evaluated by angiography and transcranial doppler. we propose that percutaneous transluminal angioplasty with stenting placement is a good therapeutic option for subclavian steal syndrome.

Abstract: spontaneous cervical arterial dissection (scad) is a non-traumatic tear or disruption in the wall of the internal carotid arteries or the vertebral arteries. it accounts for about 25% of strokes in patients aged under 45 years. awareness of its clinical features and advances in imaging over the last two decades have contributed to earlier identification of this condition. scad has become the commonest form of vascular lesion identified in the cervical carotid and vertebral arteries, second only to atherosclerosis. this review is an update on the epidemiology, vulnerable arterial segments, risk factors, clinical features, diagnosis, current treatment and prognosis of scad.

Arquivos de Neuro-Psiquiatria , 2006, DOI: 10.1590/S0004-282X2006000300001
Abstract: purpose: we preliminarily investigated the relevance of performing digital subtraction angiography (dsa) in addition to magnetic resonance angiography (mra) in definition of ischemic stroke etiology in young patients. method: dsas and mras from 17 young patients with nonlacunar ischemic stroke were blindly analyzed and their impact on stroke management was evaluated. results: etiologies were the same considering results of either dsa or mra in 12/17 cases. in 15/17 patients no changes would have been made in treatment, regardless of the modality of angiography considered. conclusion: these preliminary results suggest that dsa may be redundant in two thirds of ischemic strokes in young patients. further larger prospective studies are necessary to determine indications of dsa in this age group.

Abstract: objetive: to report a brazilian series of spontaneous cervical arterial dissections, risk factors, warning symptoms, clinical manifestations, diagnostic tests, treatment and prognosis. method: we performed the retrospective analysis of clinical and neuroradiological records (mri, a-mri and angiography) of patients with this diagnosis who were evaluated in a tertiary hospital for the period of 1997-2003. results: 48 patients (24 men) with median age 37.9 years: 26 patients with unilateral internal carotid dissection (icad), 15 with unilateral vertebral artery dissection (vad) and 7 with multivessel dissections. all patients presented neurological deficits. hypertension, smoking and dyslipidemia were the main risk factors. more than 80% of patients presented at least one initial symptom, most of them temporoparietal headache. 44% of patients with vad and only 3.4% of patients with icad had neck pain. the median interval between the onset of symptom and the appearance of neurological deficit was 5.4 days for icad and 13.5 days for vad. five patients with icad presented preceding tia. angiography was performed in 93% of patients. in 42% of these patients, mri and a-mri were associated. in three patients the diagnosis was made just through cervical mri. 75% of patients received anticoagulation. two patients received intravenous thrombolytic therapy with no complications. prognosis was good for all patients but two patients with bilateral icad died. conclusion: our results are similar to the literature, except for the low frequency of neck pain in icad patients and predominance of temporoparietal headache in cervical artery dissection patients. vascular risk factors were commonly found.

Abstract: stroke affects mainly people aged over 65 years, and atherosclerosis predominates as the main etiopathogenic factor in ischemic stroke (is). on the other hand, cardiac embolism and arterial dissection are the most frequent causes of is in patients aged less than 45 years. however, inappropriate control of traditional vascular risk factors in young people may be causing a significant increase of atherosclerosis-related is in this population. furthermore, a variety of etiologies, many of them uncommon, must be investigated. in endemic regions, neurocysticercosis and chagas' disease deserve consideration. undetermined cause has been still reported in as many as one third of young stroke patients.

Abstract: purpose: it has been suggested that mitochondrial disease may be responsible for a substantial proportion of strokes of indetermined origin. we have preliminarily screened for melas (mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes) mutations in young patients with cryptogenic strokes. method: the mitochondrial mutations a3243g and t3271c were investigated in 38 subjects aged less than 46 years. group 1: 15 patients with cryptogenic strokes; group 2: 3 patients with diagnosis of melas syndrome, including stroke-like episodes; group 3: 20 healthy subjects. results: the a3243g mutation was absent in all subjects in groups 1 and 3 but was present in all subjects in group 2. conclusion: our results do not support screening for these mutations to diagnose oligosymptomatic forms of melas in cryptogenic strokes in the absence of other features of the syndrome. we suggest that clinical findings should guide mitochondrial genetic testing.

Abstract: basilar artery (ba) dissecting aneurysms pose difficulties to treatment because both bleeding and thrombosis can happen in the same patient, clinical course is unpredictable and high morbidity is usual. we report the case of a 37-year-old woman with a ba aneurysm probably caused by arterial dissection, presenting embolic and hemorrhagic complications. the aneurysm was submitted to endovascular treatment with stenting and coil embolization. clinical and radiological results were excellent and no complications were observed, suggesting that ba stenting and coil embolization may be a safe and effective treatment for this condition.

Abstract: introduction: purposes of this study were: evaluate complications and length of stay of patients admitted with diagnosis of ischemic stroke (is) in the acute or subacute phase, in a general neurology ward in s?o paulo, brazil; investigate the influence of age, risk factors for vascular disease, arterial territory and etiology. methods: data from 191 is patients were collected prospectively. results: fifty-one patients (26.7%) presented at least one clinical complication during stay. pneumonia was the most frequent complication. mean length of stay was 16.8+-13.8 days. multivariate analysis revealed a correlation between younger age and lower complication rates (or=0.92-0.97, p < 0.001). presence of complications was the only factor that independently influenced length of stay (or=4.20; ci=1.928.84; p<0.0001). conclusion: these results should be considered in the planning and organization of is care in brazil.
Capacita??es tecnológicas de micro e pequenas empresas inseridas em redes tecnoprodutivas: o caso da eletrometal-mecanica em Joinville (SC)
Stallivieri, Fabio;Campos, Renato Ramos;Brito, Jorge;
Revista de Economia Contemporanea , 2007, DOI: 10.1590/S1415-98482007000300003
Abstract: this paper analyses the capabilities developed by micro and small companies inserted in techno-productive networks in the eletrometal-mechanic productive arrangements of the region of joinville, located in the northeast of the state of santa catarina. this arrangement is characterized by a strongly diversified and heterogeneous productive structure, with patterns of specialization and complementarities according to the size of establishments and along different activities. the analysis of the labor division in the arrangement and of the specializations by size of the companies, combined with the market interactions and the types of sub contraction, will help to comprehend how micro and small companies insert themselves in the arrangement and technological capabilities they develop. the study is based on the neo-schumpeterian theoretical framework and has as its main objective the analysis of the different technological capabilities developed by these types of firms, according to their pattern of insertion in the local productive structure. for this purpose a survey with 83 companies of different sizes was made. an important finding was the existence of several kinds of techno-productive networks, which vary according to the forms of governance, the productive and technological characteristics and the nature of the learning processes. such specificities affect, with different intensities, the possibilities of technological capacity building, which were also influenced by the relations with agents outside the arrangement.
