Many studies in the general population have shown a link between Helicobacter pylori infection and iron-deficiency, often resulting in iron-deficient anaemia. Despite the high prevalence of iron deficiency in hemodialysis patients, no studies have been performed in this population. ⋯ Helicobacter pylori infection has no effect on anaemia (hematocrit, Eritropoietin dose or iron needs) in our hemodialysis patients. Prevalence of Helicobacter pylori is lower in patients with longer time on dialysis. We consider that the diagnosis of Helicobacter pylori infection must be reserved for clinical peptic ulcer suspicion or patients on transplant waiting list.

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.
