Lanthanum carbonate oral powder: satisfaction, preference and adherence in French and Spanish patients with end-stage renal disease.

Background: Phosphate binders, such as lanthanum carbonate, control elevated serum-phosphate levels in patients with end-stage renal disease (ESRD). Lanthanum carbonate is available in oral powder and tablet form. The aim of this survey was to investigate satisfaction with, preference for, and adherence to lanthanum carbonate oral powder in patients with ESRD.

Selective venous catheterization in the evaluation of hyperandrogenism.

Retrograde bilateral ovarian-adrenal vein catheterization was carried out in 16 patients with plasma testosterone levels exceeding 1.4 ng/ml (4.85 nmol/l).

Cyproterone acetate versus hydrocortisone treatment in late-onset adrenal hyperplasia.

Thirty late-onset adrenal hyperplasia patients consulting for isolated hirsutism were randomly divided into two groups; group 1 (n = 16) was treated with hydrocortisone in order to suppress androgen adrenal secretion, and group 2 (n = 14) received cyproterone acetate (CPA) antiandrogen therapy to inhibit peripheral androgen activity. The clinical and hormonal effects of each type of treatment were evaluated. Before treatment, the clinical and hormonal profiles of the two patient groups did not differ significantly.

Prolactin secretion in benign breast diseases.

In order to evaluate the importance of prolactin in the pathogenesis of benign breast diseases (BBD), serum prolactin (PRL) levels were determined before and during a TRH challenge test in 50 patients affected by various BBD studied during the luteal phase of their cycle. They were compared to 15 normal women also studied during the luteal phase. In all the subjects estradiol (E2) and progesterone (P) were also measured.

Effect of calcitriol in the control of plasma calcium after parathyroidectomy. A placebo-controlled, double-blind study in chronic hemodialysis patients.

Severe, prolonged hypocalcemia in observed in some, but not all, hemodialysis patients after parathyroidectomy performed because of uncontrolled hyperparathyroidism. The aim of the present study was to investigate whether calcitriol and calcium supplementation in the immediate period after parathyroidectomy (days 1-14) was of more help in the control of plasma calcium than calcium supplementation alone. Fourteen hemodialysis patients were enrolled in a prospective, randomized, double-blind and placebo-controlled study.
