[Effect of vitamin D deficiency on hypocalcaemia after total thyroidectomy due to benign goitre].

Introduction: The purpose of this study was to analyse the relationship between preoperative serum levels of vitamin D and postoperative hypocalcaemia after total thyroidectomy.

Material And Methods: A prospective observational study was conducted on 113 patients treated by total thyroidectomy due to benign disease. Preoperative vitamin D serum levels and postoperative albumin-corrected calcium and parathormone (PTH) levels were determined.

[Relationship between parathormone concentration during surgery and the post-operative outcome of primary hyperparathyroidism].

Introduction: The relationship between the intra-operative concentration of parathyroid hormone (IOPTH) and the long-term outcome of patients intervened due to primary hyperparathyroidism (PHPT).

Patients And Methods: A prospective observational study was performed with 120 patients. Three determinations were made of PTH in blood: baseline, when the diseases gland was located, and 10 minutes after its extirpation.
