INTRODUCTION: Cinacalcet is a calcimimetic that modulates the functions of calcium-sensing receptor and is currently used to treat patients with primary hyperparathyroidism (PHPT). Although it was reported that cinacalcet treatment reduced the size of hyperplastic parathyroid glands in patients with secondary hyperparathyroidism, whether or not cinacalcet treatment can reduce the size of parathyroid adenomas in patients with PHPT has been unknown. MATERIALS AND METHODS: We recruited nine (male: one, female: eight) patients with PHPT due to parathyroid adenomas who did not undergo parathyroidectomy...

Importance: Parathyroidectomy provides definitive management for primary hyperparathyroidism (PHPT), reducing the risk of subsequent fracture, nephrolithiasis, and chronic kidney disease (CKD), but its use among older adults in the US is unknown. Objective: To identify patient characteristics associated with the use of parathyroidectomy for the management of PHPT in older adults. Design, Setting, and Participants: This population-based, retrospective cohort study used 100% Medicare claims from beneficiaries with an initial diagnosis of PHPT from January 1, 2006, to December 31, 2016...

Case summary: A 16-year-old neutered female Korat cat presented with chronic vomiting, mild azotaemia and mild hypercalcaemia. Physical examination revealed bilateral palpable masses on each side of the trachea. Laboratory results were consistent with primary hyperparathyroidism, diagnostic imaging findings with cystic thyroid or parathyroid masses, and fine-needle aspiration cytology with thyroid hyperplasia or adenoma. In order to confirm whether one or two of the masses were the cause of the hyperparathyroidism, cystic fluid was aspirated from both for parathyroid hormone concentration measurement...

Disturbances in mineral and bone metabolism are common in patients with chronic kidney disease (CKD), especially those undergoing dialysis. Renal osteodystrophy, which describes an alteration of bone morphology, is an important component of this systemic disorder and may explain the elevated risk of fracture which adversely affects morbidity and mortality. The most common form of renal osteodystrophy is high-turnover bone disease (osteitis fibrosa), which is induced by secondary hyperparathyroidism (SHPT). During the past decade, there has been considerable advances in the management of SHPT, with the introduction of the calcimimetic agents, the optimized use of nutritional and active vitamin D, and the accumulated experience with surgical parathyroidectomy...

Parathyroidectomy has evolved over the years from bilateral neck exploration to a single gland approach using minimally invasive surgery. The precise presurgical localization of the problem gland, using functional techniques, such as double-phase scintigraphy with [99m Tc] Tc-MIBI including SPECT-CT and PET-CT with [18 F]-Choline and morphological ones, such as ultrasound have played a crucial role in this paradigm's shift. Radioguided surgery techniques have also adapted and grown with new contributions known for their indication in other fields...

Intrathyroidal parathyroid carcinoma is an extremely rare cause of primary hyperparathyroidism. We reported a 51-year old woman who presented symptoms of hypercalcemia. 99mTc sestamibi single-photon emission computed tomography/computed tomography (CT) revealed a large hypermetabolic nodule in the left thyroid lobe suggestive of hyperfunctioning parathyroid tissue. 11C-methionine positron emission tomography/computed tomography (PET/CT) and 18F-fluorocholine PET/CT confirmed the nodule in the left thyroid lobe and also revealed a hypermetabolic activity on the posterior surface of the lower left pole...

BACKGROUND: In chronic kidney disease, serum phosphorus (P) elevations stimulate parathyroid hormone (PTH) production, causing severe alterations in the bone-vasculature axis. PTH is the main regulator of the receptor activator of nuclear factor κB (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) system, which is essential for bone maintenance and also plays an important role in vascular smooth muscle cell (VSMC) calcification. The discovery of a new RANKL receptor, leucine-rich repeat-containing G-protein-coupled receptor 4 (LGR4), which is important for osteoblast differentiation but with an unknown role in vascular calcification (VC), led us to examine the contribution of LGR4 in high P/high PTH-driven VC...

Current treatment guidelines recommend surgical excision of papillary thyroid carcinoma. However, the precise surgical treatment, including thyroid lobectomy, total thyroidectomy, and the need for neck dissection, is dictated by disease extent and tumor cytology. Incidental papillary thyroid carcinoma discovered during another surgery therefore presents a surgical conundrum due to lack of information. Surgeons must consider short- and long-term surgical morbidities, as well as individual patient factors, when deciding how to treat an unexpected thyroid carcinoma...

Primary hyperparathyroidism is an endocrine disorder characterized by hypercalcemia and elevated or inappropriately normal levels of parathyroid hormone. The diagnosis is based on a biochemical evaluation, and a neck ultrasound is the first choice during pregnancy to access the parathyroid glands. Manifestations during pregnancy are rare and can be present with life-threatening complications, so the diagnosis is challenging. The conservative treatment is limited, and there is not enough data about its safety and efficacy during pregnancy...

BACKGROUND: Intraoperative near-infrared imaging (NIFI) of parathyroid glands (PG) by first-generation technology had limited image quality and depth penetration. Second-generation NIFI has recently been introduced. Our aim was to compare (1) capability to detect PG and (2) image quality between older and newer technologies. METHODS: Accurately detecting PG, as well as, quality of autofluorescence (AF) was compared between an older charge-coupled device (CCD) camera and a newer complementary metal-oxide semiconductor (CMOS)...

OBJECTIVE: Geriatric patients are often reluctant to undergo parathyroid surgery under general anesthesia because of the major comorbidities. The use of minimally invasive techniques for parathyroid lesions under local anesthesia have been published. Radioguided lesion localization has been known to decrease operative time and reduce the occurrence of positive margins in breast cancer surgery. We hypothesize that it could also be effectively used in focused parathyroid surgery in geriatric patients with in history of thyroid surgery...

Hyperparathyroidism leading to hypercalcaemia is a rare cause of acute pancreatitis with debatable association. The diagnosis of hyperparathyroidism is frequently overlooked or delayed as symptoms are non-specific and serum calcium is not routinely measured in acute pancreatitis. Early diagnosis and treatment of hyperparathyroidism may reduce the chances of complications. We report a 35-year-old woman, who was admitted with recurrent episodes of acute pancreatitis. She was previously diagnosed with gall-stone induced acute pancreatitis, had undergone laparoscopic cholecystectomy, but the recurrence of acute pancreatitis suggested an alternative aetiology and provoked extensive investigations...

INTRODUCTION: Surgical treatment of hyperparathyroidism related to chronic kidney disease is a real challenge for Brazilian public health care. High cost medications and long waiting lines to perform preoperative exams, especially technetium Tc 99m Sestamibi (MIBI) are some of the reasons. Despite the reality that the aid of localization exams are questionable in this scenario, doctors are too apprehensive in performing surgery without it. OBJECTIVE: The study aimed at evaluating the efficacy of surgery for renal hyperparathyroidism without preoperative MIBI...
