SUMMARY Sixty seven hypertensive children age 2-18 with at least one possible clinical sign of renovascular hypertension (RVH) were enrollment into a screening program for diagnose and treatment of RVH over a 19 year period. Patients underwent a variety of biochemical and imaging studies, but in all cases, renal arteriography was used to determine the precise diagnosis and treatment strategy. Of the 67 patients 21 (31.3%) were identified with renal artery stenosis Group 1, 14 (66.6%) unilateral, 5 (23.8%) bilateral and 2 (9.6%) branches. ⋯ On december 2004, 19/21 (90%) RVH adolescents blood pressure was normalized with normal serum creatinina, 10 (48%) of these completed cured, 9/21 (43%) improved (normotensión with decrease in medication requirements) and 2 (9%) other cases ware lost of follow-up. The 46 non-RVH adolescents (68.7%) were treated with long term antihypertensive medications; all of these have adequate BP control and normal renal function. We conclude that our work-up used in order to make a proper and timely diagnosis and treatment of renovascular hypertension in adolescent was successful in our population.

Case Reports
[Prolonged acute renal failure and severe polyradiculopathy in ethylene glycol intoxication].
Ethylene glycol intoxication involves acute renal failure and severe metabolic acidosis. Prolonged renal insufficiency can occur but terminal chronic renal failure has been reported in very few cases. We describe a patient who after ingestion of 920 ml of ethylene glycol developed prolonged acute renal failure needing hemodialysis for 37 days and then he partly recovered renal function. The patient developed a severe sensitive-motor and autonomic polyradiculopathy.
