In the current era of early detection of chronic kidney disease and efficient therapeutic options for management of its complications, skeletal manifestations of renal hyperparathyroidism are increasingly rare. A 31-year-old female patient presented for evaluation of severe pain in the left forearm, right hand, right knee, right hip, and lower back following a fall sustained 3 days prior to presentation. She had a history of end-stage renal disease and received maintenance hemodialysis. Review of the medical records revealed that she had poor compliance with her diet, medications, and dialysis treatments...

We report here an interference that has been observed with 2nd generation PTH assays (PTH2), but not with 3rd generation PTH ones (PTH3), during PTH monitoring occurring in a surgical intervention for the resection of a parathyroid adenoma. The patient was cured and calcium levels returned to normal the next day, but PTH did not decrease with PTH2 whereas it decreased by 50% with PTH3 assays during the intervention. The reason is probably a PTH fragment released by the parathyroid gland during surgery. This fragment possesses the C-terminal part of the peptide but lacks the first amino-acids and may thus be considered as a member of the non-(1-84) PTH fragments family...

PURPOSE: Intraoperative localisation and preservation of parathyroid glands improves outcomes following thyroid and parathyroid surgery. This can be facilitated by fluorescent imaging and methylene blue; a fluorophore is thought to be taken up avidly by parathyroid glands. This preliminary study aims to identify the optimum dose of methylene blue (MB), fluorescent patterns of thyroid and parathyroid glands and develop a protocol for the use of intravenous MB emitted fluorescence to enable parathyroid identification...

Primary hyperparathyroidism is the most common hormonal manifestation associated with multiple endocrine neoplasia 1 (MEN1). It is generally caused by parathyroid hyperplasia, and parathyroid carcinoma is rare. Here, we report a case of MEN1 with parathyroid carcinoma in two parathyroid glands causing primary hyperparathyroidism. A 40-year-old man with primary hyperparathyroidism due to MEN1 underwent a total parathyroidectomy. His corrected calcium and intact PTH (i-PTH) serum levels were 10.8 mg/dL and 203 pg/mL, respectively...

A 57-year-old man presented with persistent hyperparathyroidism following primary parathyroidectomy. A four-dimensional computed tomography scan with three-dimensional reconstruction showed two parathyroid glands (one right and one left) and anatomic variation from previous surgery. Revision surgery was performed revealing the parathyroid glands as expected from the preoperative three-dimensional reconstruction. After surgery, the patient recovered well, and preoperative symptoms resolved. The use of three-dimensional computed tomography reconstruction provided accurate localization of the parathyroid glands and surrounding anatomic structures...

Background: Hypocalcemia is one of the most common postoperative complications following thyroid surgery in clinical practice. The occurrence of hypocalcemia is mainly attributed to hypoparathyroidism when parathyroid glands are devascularized, injured, or dissected during the surgery. The aim of this study was to analyze the risk factors for hypocalcemia and hypoparathyroidism following thyroidectomy. Patients and methods: A total of 278 patients who underwent thyroid surgery were analyzed retrospectively...

PURPOSE: Increased parathyroid hormone (PTH) is commonly associated with obesity, and its role in the pathogenesis of obesity-related glucometabolic abnormalities is uncertain. We aimed to explore the relationships of PTH with glucose/insulin homeostasis parameters before and after bariatric surgery-induced weight loss, and whether they depend or not on 25-hydroxyvitamin D (25OHD) status. METHODS: We included 42 subjects (27 women, aged 40 ± 5 years, BMI 48...

Pharyngeal pouches in mammals develop into specific derivatives. If the differentiation of the pharyngeal pouches is anomalous, their remnants can result in cysts, sinuses, and fistulae in the differentiated organs or around the neck. In the present study, we found several pharyngeal pouch remnants, such as cystic structures in thymus and parathyroid gland and fossulae extended from the piriform fossa, in the inbred cotton rats maintained at Hokkaido Institute of Public Health (HIS/Hiph) and University of Miyazaki (HIS/Mz)...

Parathormone (PTH), produced by parathyroid glands, is the main regulator of calcium homeostasis. Hypoparathyroidism (hypoPT), due to decrease of PTH production, is a rare disease. Symptoms are multiple, altering function of several organs and leading to a decrease of quality of life. Acquired etiologies, including thyroïdectomy, the main cause of hypoPT, can be distinguished from congenital etiologies, including genetic defects. HypoPT, which is classically treated by supplementation by calcium and active vitamin D, can now be treated by recombinant injection in certain indications as a poor control under classical therapy...

Hypoparathyroidism (HPT) is one of the most frequentand severe complications of thyroid surgery. It is caused by intraoperative damage, devascularization or accidental removal of the parathyroid glands (PTGs). The incidence of postoperative HPT is directly proportional to surgery extent and surgeon's experience. After 40 years of experience in thyroid surgery, the first author summarizes the already known surgical steps in thyroid surgery and adds some useful practical tips for in situ preservation of PTGs...
