We report herein a case of intrathyroidal parathyroid hyperplasia in a patient with tertiary hyperparathyroidism. The patient was recommended for parathyroidectomy due to sustained hypercalcemia after kidney transplantation. Preoperative radiologic evaluations showed a benign-looking thyroid mass and three enlarged parathyroid glands. Intraoperative intact parathyroid hormone (iPTH) level and f...

Parathyroid hormone (PTH) regulates mineral metabolism and bone turnover by activating specific receptors located on osteoblastic and renal tubular cells and is fully functional as the N-terminal 1-34 fragment, PTH-(1-34). Previously, a "U-shaped" conformation with N- and C-terminal helices brought in close proximity by a turn has been postulated. The general acceptance of this hypothesis, desp...

Arch Clin Exp Med. 2017;2(3):84-86. Abstract Parathyroid cancer is a rarely encountered disease which may accompany with hyperparathyroidism. It is hard to diagnose the disease before surgical treatment and t...

We report the case of a 60-year-old woman with a multinodular goitre who underwent total thyroidectomy and was found intraoperatively to have a parathyroid ‘incidentaloma’. The surgical approach to the management of patients with incidental parathyroid disease is discussed and a review of the literature is presented.

The identification of parathyroid gland tissue and its distinction from surrounding structures such as thyroidgland, lymphoid, fibroadipose, and, rarely, thymic tissues on frozen section (FS) may be challenging owingto freezing artifact and small biopsy sent for FS. Intraoperative cytology (IC) provides valuable complementary morphologic details. We evaluated a case by IC alone, followed by int...

UNLABELLED This study was undertaken to determine the effects of collimators on the accuracy of preoperative sestamibi parathyroid imaging of the neck. METHODS Forty-nine patients with primary hyperparathyroidism underwent preoperative (99m)Tc-sestamibi parathyroid imaging. The protocol included early and late pinhole and parallel-hole imaging. One experienced nuclear physician, without knowl...

Ectopic and/or supernumerary parathyroid glands are a major cause of persistent and recurrent Hyperparathyroidism (HPT). For this reason, it is widely accepted that preoperative localization should be performed to improve the surgical results in patients with persistent or recurrent HPT. Primary HPT (pHPT) was diagnosed incidentally in a 50-year old female patient during a preoperative examinat...

Number, location and surrounding structures of parathyroid glands with emphasis on parathyroidectomy were studied on 101 cadaverous bodies. Number of collected samples from all known locations of parathyroid glands varied from three to five in one individual, with mean 3.71 +/- 0.62. We identified 80% of samples as parathyroid glands. Mean number of correctly identified parathyroid glands in on...

A 46 year-old male presented with persistently high level of serum parathyroid hormone (PTH), despite successful resection of an oxyphilic cell parathyroid adenoma of the left lower gland. Renal function and serum calcium were normal, leading to vitamin D deficiency being considered. Tc99m-sestamibi parathyroid scintigraphy showed no capitation, but a cervical ultrasound demonstrated an increas...

We have examined if there are any differences in intraoperative and early postoperative concentrations of parathyroid hormone between the first group of patients, who had thyroidectomy surgery performed by harmonic scalpel, and the second group of patients operated on by standard techniqes with the use of electrocoagulation and ligature as primary hemostatic procedures. All the patients having ...
