Aumento de distensibilidade arterial e hipertensão renovascular na Sindrome de Goldenhar

This is a report of the successful angioplastic treatment of an association of renovascular hypertension with renal artery stenosis and the Goldenhar syndrome (a variant of oculoauriculovertebral dysplasia). For the first time to date, this association, which occurred in a 13-year-old girl, is reported. Additionally, increased arterial distensibility in spite of arterial hypertension was detected by noninvasive methods. The similarity of this finding and in those for other genetic diseases, suggests that the vascular lesions could be linked to the Goldenhar syndrome.Relatamos a associação de hipertensão renovascular por estenose de artéria renal e a Sindrome de Goldenhar (variante da displasia oculoauriculovertebral) em uma paciente do sexo feminino de 13 anos de idade. Este é o primeiro relato de tratamento por angioplastia. Além disso, detectamos por métodos não invasivos um aumento da distensibilidade arterial, a despeito da hipertensão arterial. A similaridade destes achados com outras doenças genéticas sugere que as alterações vasculares presentes podem estar relacionadas à Síndrome de Goldenhar

O BNDES e as empresas de consultoria na reorganização do território brasileiro na década de 1990

The present article has the objective of analyzing BNDES’ role in the Brazilian territory reorganization. The concerns with industrialization, territory integration and the overcoming underdevelopment substantiated the creation of the Bank in the early 1950’s. In a short period of time, BNDES became one of the major references of State planning and essential to the main national projects of distinct orientations. Nowadays, with the intensification of globalization rationality, BNDES has been determinant for the elaboration and operationalization of a normative project, favorable to the territory internationalization. The assumption in this paper is that the vigorous privatization process coordinated by the Bank, with the endorsement of consultancy companies, has been enlarging the unequal generation and appropriation of income and intensifying the corporate use of territory.O presente artigo busca analisar o papel do BNDES na reorganização do território brasileiro. As preocupações com a industrialização, com a integração do território e com a superação do subdesenvolvimento fundamentaram a criação do Banco em 1952. Em pouco tempo, o BNDES se tornou uma das principais referências de planejamento da burocracia estatal e, imprescindível, aos principais projetos nacionais das mais diversas orientações. No período atual, com a intensificação da racionalidade da globalização, o BNDES tornou-se central na elaboração e operacionalização de um quadro normativo favorável à internacionalização do território. Parte-se da hipótese que o vigoroso processo de privatização coordenado pelo Banco, com o aval das empresas de consultoria, tem ampliando a desigual geração e apropriação de riqueza, bem como intensificado o uso corporativo do território

The contrast-enhanced Doppler ultrasound with perfluorocarbon exposed sonicated albumin does not improve the diagnosis of renal artery stenosis compared with angiography

There are no studies investigating the effect of the contrast infusion on the sensitivity and specificity of the main Doppler criteria of renal artery stenosis (RAS). Our aim was to evaluate the accuracy of these Doppler criteria prior to and following the intravenous administration of perfluorocarbon exposed sonicated albumin (PESDA) in patients suspected of having RAS. Thirty consecutive hypertensive patients (13 males, mean age of 57 ± 10 years) suspected of having RAS by clinical clues, were submitted to ultrasonography (US) of renal arteries before and after enhancement using continuous infusion of PESDA. All patients underwent angiography, and haemodynamically significant RAS was considered when ≥50%. At angiography, it was detected RAS ≥50% in 18 patients, 5 with bilateral stenosis. After contrast, the examination time was slightly reduced by approximately 20%. In non-enhanced US the sensitivity was better when based on resistance index (82.9%) while the specificity was better when based on renal aortic ratio (89.2%). The predictive positive value was stable for all indexes (74.0%–88.0%) while negative predictive value was low (44%–51%). The specificity and positive predictive value based on renal aortic ratio increased after PESDA injection respectively, from 89 to 97.3% and from 88 to 95%. In hypertensives suspected to have RAS the sensitivity and specificity of Duplex US is dependent of the criterion evaluated. Enhancement with continuous infusion of PESDA improves only the specificity based on renal aortic ratio but do not modify the sensitivity of any index

Malignant hypertension and hypertensive encephalopathy in primary aldosteronism caused by adrenal adenoma

Two cases are reported as follows: 1) 1 female patient with accelerated-malignant hypertension secondary to an aldosterone-producing adrenal adenoma; and 2) 1 female patient with adrenal adenoma, severe hypertension, and hypertensive encephalopathy. This association is a rare clinical finding, and malignant hypertension may modify the hormonal characteristic of primary aldosteronism, making its diagnosis more difficult. The diagnosis of primary aldosteronism should be considered in patients with malignant hypertension or hypertensive encephalopathy if persistent hypokalemia occurs. Identification of primary aldosteronism is of paramount importance for the patient's evolution, because the surgical treatment makes the prognosis more favorable
