Renovascular hypertension : practical suggestions for clinical diagnosis and treatment
Nos Ășltimos anos, muitos avanços tĂȘm ocorrido na ĂĄrea clĂnica da hipertensĂŁo renovascular. O uso de mĂ©todos diagnĂłsticos e de modalidades terapĂȘuticas menos invasivos tem recebido ĂȘnfase especial. Este artigo de revisĂŁo procura apresentar orientaçÔes clĂnicas, prĂĄticas e confiĂĄveis, atualmente em uso em centros mĂ©dicos de vanguarda.During the last few years, many advancements have been made in the clinical field of renovascular hypertension. Emphasis is now being placed on the use of less invasive diagnostic methods and treatment modalities. Our objective is to present practical and reliable clinical guidelines that are currently being used in cutting-edge medical centers
NEFROPATIA ISQUĂMICA
O presente artigo aborda a nefropatia isquĂȘmica â entidade cada vez mais reconhecida como causa importante de insuficiĂȘncia renal crĂŽnica, principalmente em populaçÔes com alto risco cardiovascular â e atualiza conhecimentos sobre epidemiologia, etiologia, fisiopatologia, manifestaçÔes clĂnicas e tratamento da referida entidade. Uma abordagem sistemĂĄtica do assunto Ă© proposta. Unitermos: Nefropatia isquĂȘmica, estenose de artĂ©ria renal, insuficiĂȘncia renal crĂŽnica, aterosclerose, hipertensĂŁo renovascular

Ischemic nephropathy
O presente artigo aborda a nefropatia isquĂȘmica â entidade cada vez mais reconhecida como causa importante de insuficiĂȘncia renal crĂŽnica, principalmente em populaçÔes com alto risco cardiovascular â e atualiza conhecimentos sobre epidemiologia, etiologia, fisiopatologia, manifestaçÔes clĂnicas e tratamento da referida entidade. Uma abordagem sistemĂĄtica do assunto Ă© proposta.The present article is a review about ischemic nephropathy, a clinical entity that has gained recognition as a major cause of chronic renal failure, mainly in populations at higher cardiovascular risk. The literature about the epidemiology, etiology, pathophysiology, clinical manifestations and treatment aspects of this disease are revised and a systematic approach to it is proposed
Calciuria and preeclampsia
Urinary calcium excretion has been reported to be diminished in preeclampsia. The objective of the present study was to determine urinary calcium excretion in pregnant patients with chronic arterial hypertension (CAH) and preeclampsia (PE), and in normotensive patients (N). Forty-four pregnant patients (gestational age, 20-42 weeks; 18 CAH, 17 PE, 9 N) were evaluated for calciuria, proteinuria, plasma uric acid and blood pressure. Patients with PE (82 ± 15.1 mg/ 24 h) showed significantly lower calciuria (P<0.05) than the group with CAH (147 ± 24.9 mg/24 h) and the N group (317 ± 86.0 mg/24 h) (P<0.05, Student t-test). Plasma uric acid was significantly higher in the PE group (6.1 ± 0.38 mg/dl) than the CAH group (5.0 ± 0.33 mg/ dl; P<0.05), which also presented higher proteinuria levels, although the difference was not statistically significant. Diastolic and systolic blood pressure did not differ between the PE (164 ± 105 mmHg) and CAH (164 ± 107 mmHg) groups. Calciuria was significantly lower in the group with preeclampsia than in the group with chronic arterial hypertension. We conclude that calciuria can be a further factor for identifying preeclampsia
