BACKGROUND Phosphate (P) control is crucial to prevent secondary hyperparathyroidism and extraosseous calcification. Hemodialysis techniques normally used do not remove the amount of P absorbed from an adequate protein intake. Our long hemodialysis (LHD) procedure produces greater P removal in a seven-hour session than in a conventional four-hour session.(More)
BACKGROUND The place of parathyroid gland imaging by [(99m)Tc](technetium)-sestamibi scintigraphy in uraemic patients with secondary hyperparathyroidism remains a matter of debate. The purpose of the present study was (i) to assess its value with respect to plasma intact parathyroid hormone (iPTH) levels and to surgical parathyroidectomy (PTx), and (ii) to(More)
Induction of anesthesia is associated with an increased incidence of cardiac arrhythmias in patients maintained on amitriptyline medication. This study presents additional evidence showing that, in experimental animals (cats), amitriptyline treatment also produces significant ST-T wave and conduction abnormalities during neostigmine reversal of(More)
Introduction: The mineral bone disorder, particularly secondary hyperparathyroidism, in chronic kidney disease (CKD) has a systemic impact affecting not only bone metabolism. Therefore its correction is important to prevent cardiovascular, inflammatory and immune diseases. Objective To assess the effectiveness and safety of intravenous paricalcitol(More)
The usefulness of technetium-99m-sestamibi (99mTc-MIBI) in patients with secondary hyperparathyroidism on haemodialysis was assessed. We studied 33 patients with parathyroid scintigraphy with i.v. (99mTc-MIBI). Static images in a scintillation camera were taken at 15 and 120 min after the injection. With P x Ca<80, we performed an inhibition test with(More)
With the purpose of studying the curve of parathyroid response to variations of serum calcium during dialysis, we studied 20 patients on haemodialysis: 10 women and 10 men, with different forms of bone disease diagnosed by bone biopsy (adynamic bone disease, mild hyperparathyroidism, severe hyperparathyroidism). In all patients, we performed parathyroid(More)
Sixteen young male students participated in two studies designed to determine the nitrogen balance response to beef or stone-ground, whole wheat protein over the submaintenance-to-maintenance range of protein intake. The objective of the studies was to evaluate the relative capacities of these proteins to meet the minimum protein needs in young adult males.(More)
