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...

BACKGROUND AND PURPOSE Dahl salt-sensitive rats fed an 8.7% NaCl diet exhibited hypertensive encephalopathy and developed seizures associated with areas of blood-brain barrier (BBB) disruption without brain ischemia. The incidence of hemorrhagic stroke was low (7/47). We tested the hypothesis that a defect in cerebral blood flow (CBF) autoregulation under hypertensive conditions preceded hypert...

Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiologic entity with several well-known causes such as hypertensive encephalopathy, eclampsia, uremia, antirejection therapy, chemotherapeutic agents, characterized as rapid onset of symptoms (including headache, visual disturbance, seizures, altered consciousness) and typical neuroimaging features, which usually resolve over sev...

PURPOSE The aim of this study was to assess the clinical characteristics of hypertensive encephalopathy according to the underlying etiologies in children. METHODS We retrospectively evaluated 33 pediatric patients who were diagnosed as having hypertensive encephalopathy in Chonbuk National University Children's Hospital. Among the patients, 18 were excluded because of incomplete data or beca...

Abstract Background Hashimoto’s encephalopathy (HE) is a rare but controversial syndrome showing variety of neurological and psychiatric manifestations associated with autoimmune thyroiditis. Case presentation We present case 46-year-old hypertensive female who developed acute onset behavioral symptoms mimicking affective disorder (mania). Investigations revealed high levels anti-thyroid peroxi...

Disruption of the blood-brain barrier may play a major role in the pathogenesis of hypertensive encephalopathy. In this study we determined whether sympathetic nerves to cerebral vessels protect the blood-brain barrier during chronic hypertension. We removed the cervical sympathetic ganglion on one side in 24 stroke-prone hypertensive rats when they were 1 month old. After signs of cerebral dys...

A child with solitary functioning hydronephrotic kidney and hypertensive encephalopathy is described. Removal of the contralateral dysplastic kidney failed to normalize his blood pressure.

The most common cause of malignant hypertension in children is renal or renovascular pathology. The combination with lethargy suggests a diagnosis of hypertensive crisis with hypertensive encephalopathy. Here, we present a case of severe hypertension with lethargy as the sole presenting symptoms of ileocecal intussusception. Both normalized following surgical repositioning. We conclude that mal...

Certain chemical and pharmacological properties of sodium nitroprusside, a cheap, readily available chemical, have been described. It is a powerful hypotensive agent when given intravenously to hypertensive patients. It is no more effective than the sodium thiocyanate into which it is converted when given by mouth. Prolonged infusion has proved highly effective in the treatment of hypertensive ...
