Delayed Calcium Normalization after Successful Parathyroidectomy in Primary Hyperparathyroidism.

Introduction: Parathyroidectomy is the curative treatment option in primary hyperparathyroidism (PHPT). The decrease of parathormone (PTH) by 50% or more from levels prior to surgery after excision predicts successful parathyroidectomy. Serum calcium is expected to return to normal within 24-72 hours after the surgery; however, nearly 10% have transient, persistent postoperative hypercalcemia.

Background: Thyroidectomy is one of the most common procedures and the most feared complication is the hematoma that obstructs the airway, which leads to the use of drains, although the evidence of the benefits of its use is limited.

Objective: To analyze the frequency of the use of drains, the type of surgery and hospital stay in patients undergoing thyroid surgery.

Method: We included patients with diverse thyroid diseases with and without drains.

Factors associated with malignancy in patients with thyroid nodules.

Background: Due to the development of diagnostic techniques, the incidence of thyroid nodule reporting is increasing. Most of these cases may be managed conservatively, but it is important to identify those with a high suspicion of malignancy. The aim of this study was to identify factors that relate to malignancy in patients with thyroid nodule.
