Flow cytometric DNA analysis of parathyroid benign lesions.

Introduction: It is difficult to differentiate benign and malignant lesions just by histopathological evaluation due to lack of clear criteria of diagnosis. Moreover, the group of benign pathologies of parathyroids is not homogenous, and recurrence of symptoms of hyperparathyroidism after surgical management was also noted in this group. This complication is not always due to inappropriate surgical technique.

Oxidative stress in proliferative lesions of parathyroid gland.

Background: Primary hyperparathyroidism (PHPT) is one of the most common endocrine disorders and defined as excessive secretion of parathormone. PHPT is a risk factor of several cardiovascular diseases, which could be caused by alterations in oxidant-antioxidant balance.

Materials And Methods: Blood serum collected from 52 consecutive patients with PHPT treated surgically constituted our study material, whereas 36 healthy volunteers were our control group.

A follow-up study of patients with MEN syndromes - five case reports.

The Aim Of The Study: Evaluation of the results of surgical treatment in patients with hyperparathyroidism related to MEN syndrome MATERIALS AND METHODS: The group of three women and two men aged between 17 and 72 years ( av. 38.6) with MEN- related hyperparathyroidism within 419 patients were operated between 2010-2016.
