1/181. Transient paralytic attacks of obscure nature: the question of non-convulsive seizure paralysis.Eleven patients with transient paralytic attacks of obscure nature are described. paralysis could involve face or leg alone, face and hand, or face, arm and leg. The duration varied from two minutes to one day. Four patients had brain tumors, six probably had brain infarcts, and one a degenerative process. The differential diagnosis included TIAs, migraine accompaniments, and seizures. In the absence of good evidence for the first two, the cases are discussed from the standpoint of possibly representing nonconvulsive seizure paralysis (ictal paralysis, inhibitory seizure paralysis or somatic inhibitory seizure). Because of the difficulty in defining seizures as well as TIAs and migraine in their atypical variations, a firm conclusion concerning the mechanisms of the spells was not attained. Two cases of the hypertensive amaurosis-seizure syndrome have been added as further examples of ictal deficits.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
2/181. Angioplasic surgery for renal artery aneurysm in pediatric hypertension.Aneurysmectomy and renal angioplasty were performed on a 14-year-old Japanese male and the blood pressure was within normal values 3 years after this surgery. Measurement of renal blood flow was facilitated by using 133Xe washout technique. This incidence is the eighth such case to be reported from japan.- - - - - - - - - - ranking = 171998.85955246keywords = aneurysm, artery, artery aneurysm (Clic here for more details about this article) |
3/181. Ask-Upmark kidney associated with renal and extrarenal arterial aneurysms.Reports of Ask-Upmark kidney, initially described as a congenital defect in renal development, are uncommon. We report a case with the features of bilateral asymmetrical segmental atrophy in a patient with childhood-onset hypertension. As an adult, she developed cerebral, celiac, and renal artery aneurysms. She underwent successful clipping of the cerebral aneurysm and renal artery repair with preservation of renal function. Novel radiologic techniques make possible the noninvasive diagnosis of segmental atrophy and its complications.- - - - - - - - - - ranking = 247247.16296816keywords = aneurysm, artery, artery aneurysm, cerebral (Clic here for more details about this article) |
4/181. Coexistence of atherosclerotic renal artery stenosis with primary hyperaldosteronism.The discovery of two forms of secondary hypertension in the same patient is unusual and suggests similar pathophysiological mechanisms, a predisposition to one type in the presence of the other or a chance occurrence. We describe two patients with renal artery stenosis who after successful correction of the stenotic lesions were discovered to have primary hyperaldosteronism associated with bilateral adrenal hyperplasia. Initially prior to revascularisation of the renal artery stenosis, the diagnosis of primary hyperaldosteronism was not evident. Both patients were subjected to further diagnostic evaluation after the appearance of hypokalaemia in one patient and continued resistant hypertension in both patients. The addition of spironolactone therapy reduced blood pressure impressively in both patients. Clinicians should be aware of the possibility that these two forms of secondary hypertension may be present in the same patient and that optimal blood pressure control requires diagnostic assessment and intervention for both disorders.- - - - - - - - - - ranking = 7236.3699550433keywords = artery (Clic here for more details about this article) |
5/181. Kawasaki disease complicated by renal artery stenosis.We report the case of a child who developed severe renovascular hypertension six months after acute Kawasaki disease. The hypertension was well controlled with enalapril, but there was a gradual decrease in function of the affected kidney. The lesion, an ostial stenosis of the right main renal artery, was not amenable to percutaneous balloon angioplasty, so was treated with bypass surgery. Vasculitis is an important cause of renovascular hypertension in children. This case highlights the importance of regular blood pressure monitoring in children with a history of systemic vasculitis.- - - - - - - - - - ranking = 6030.3082958694keywords = artery (Clic here for more details about this article) |
6/181. plasma brain natriuretic peptides and renal hypertension.Three children with renal hypertension are described. Two had histories of neuroblastoma treated by surgical resection and chemotherapy. They both presented later with unilateral atrophic kidney and marked hypertension. Only the child with severe cardiac failure demonstrated high plasma brain natriuretic peptide (BNP) concentrations. The remaining patient had a history of chronic nephritis treated with continuous ambulatory peritoneal dialysis. She also had chronic hypertension and severe cardiac failure. This child demonstrated high plasma BNP levels. The endogenous secretion of BNP is not triggered by hypertension alone, even though exogenous BNP has the pharmacological effect of reducing renin activity.- - - - - - - - - - ranking = 2.5keywords = brain (Clic here for more details about this article) |
7/181. Perinatal renal ischemia resulting in hypertensive cardiomyopathy.Three neonates presented with malignant hypertension during the first week of life; 2 of them had congestive heart failure. Although none had indwelling umbilical artery catheters, unilateral renovascular lesions were diagnosed by nuclear perfusion scans. Angiotensin-converting enzyme inhibitor therapy produced rapid recovery. hypertension must be included in the differential diagnosis of infants presenting with congestive heart failure and acidosis. ultrasonography is not sensitive enough to exclude renovascular lesions. We emphasize the importance of early diagnosis and treatment.- - - - - - - - - - ranking = 1206.0616591739keywords = artery (Clic here for more details about this article) |
8/181. Covered stent for renal artery aneurysm.This is a case of a 51-year-old female with difficult-to-control hypertension and a 3-cm renal artery aneurysm. Successful exclusion of this was performed using a prefabricated stent graft. To our knowledge, this is the first report on the use of a prefabricated covered stent for this indication.- - - - - - - - - - ranking = 214998.57444058keywords = aneurysm, artery, artery aneurysm (Clic here for more details about this article) |
9/181. Hyponatremic hypertensive syndrome.We report on a 4-year-old girl with hyponatremic-hypertensive syndrome (HHS), a rare entity in childhood. The girl was referred to us from a local hospital with a history of recurrent fever, vomiting, and seizures. On admission she was markedly dehydrated. Initial investigations revealed severe hyponatremia (serum Na 120 mmol/l), hypochloremia (serum Cl 68 mmol/l), and mild hypokalemia (serum K 3.3 mmol/l), while serum calcium and magnesium were normal. serum urea was 5 mmol/l and serum creatinine was 62 mumol/l. Despite hyponatremic dehydration, her urine output was high (2050 ml/24 h), as was her urinary sodium (168 mmol/24 h). She had massive transient proteinuria (maximal 1642 mg/24 h) while being severely hypertensive (blood pressure 210/160 mmHg). Further investigations revealed right kidney scarring, hyper-reflexive bladder dysfunction, massive brain infarcts, and myocardial left ventricular hypertrophy. Renal arteries were normal on arteriography. blood pressure control resulted in normalization of serum and urinary electrolytes and decrease of proteinuria. hyponatremia and transient massive proteinuria in this patient seem to be caused by high-pressure-forced diuresis due to malignant renoparenchymal hypertension.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
10/181. Traumatic arteriovenous fistula of the kidney; an unusual cause of hypertensive encephalopathy.A patient with a traumatic arteriovenous fistula of the kidney developed encephalopathy with seizures and was unconscious for 48 hours before undergoing a left nephrectomy, excision of a false aneurysm of the left renal artery, and colostomy closure. He has remained in good health for two years following the final operative intervention.- - - - - - - - - - ranking = 41809.448798337keywords = aneurysm, artery (Clic here for more details about this article) |
