A 23-year-old man with minimal-changed nephrotic syndrome presented reversible posterior leukoencephalopathy syndrome (RPLS) which manifested as visual disturbance, renal hypertension, headache, generalized seizure and altered mental status. T2-weighted images and fluid-attenuated inversion recovery images magnetic resonance imaging (MRI) showed high signal intensity lesions in the right poster...
The syndrome of autonomic dysreflexia often occurs in quadriplegic subjects and is characterized by paroxysmal hypertension, headache, vasoconstriction below and flushing of the skin above the level of transection, and bradycardia. These attacks may cause hypertensive encephalopathy, cerebral vascular accidents, and death. In five patients during crises, the mean arterial pressure changed from ...
Pheochromocytoma crisis is a rare life-threatening event that may appear with a variety of clinical symptoms. We present three cases of life-threatening crisis in which magnesium sulfate was particularly beneficial in controlling symptoms and signs when more conventional forms of therapy had failed. Two patients presented with hypertensive encephalopathy, and the third presented with catecholam...
We reviewed retrospectively 94 patients who had undergone soft-tissue release to correct flexion contracture of the knee to determine the incidence of postoperative hypertension. The cause of contracture in most patients was cerebral palsy (45) or old poliomyelitis (39). Twenty patients developed persistent hypertension. Two of them were symptomatic, one developing hypertensive encephalopathy. ...
Reversible posterior leukoencephalopathy syndrome associated with hypertension rarely presents with predominant involvement of the brainstem and sparing of the supratentorial regions. In this study, the clinical and neuroimaging features of a 39-year-old woman with hypertensive encephalopathy and magnetic resonance imaging (MRI) findings localized to pons and bilateral middle cerebellar peduncl...
With 60 million Americans meeting criteria for either essential or secondary hypertension, elevated arterial pressures remain a major health problem. While efforts to find etiologies for essential hypertension continue, clinicians battle its effects on organ systems, including the nervous system. Hypertensive changes in the nervous system may be acute, chronic, or both. The intracerebral vascul...
background and aim: neonatal jaundice is one of the common causes of early sensorineural hearing loss and an important cause of deafness in children. auditory responses are the most sensitive parts of the nervous system to the toxic effect of bilirubin. this study was aimed to examine the effect of neonatal hyperbilirubinemia and its treatment on auditory brainstem responses (abr). methods: ...
to evaluate the value of random urinary protein creatinine ratio in prediction of 24h proteinuria in hypertensive pregnancies. method: random urine samples and routine 24h urine collections were collected from hypertensive pregnant women (n=100). reliability of random urinary protein-creatinine ratio was assessed by receiver operator characteristic (roc) curve to detect significant proteinuria ...
intravenous hydralazine is a commonly administered arteriolar vasodilator that is effective for hypertensive emergencies associated with pregnancy. oral nifedipine is an alternative in management of these patients. in this study the efficacy of nifedipine and hydralazine in pregnancy was compared in a group of iranian patients. fifty hypertensive pregnant women were enrolled in the study. a ran...
