OBJECTIVE: The aim of this study was to further elucidate the mechanisms of dual-phase technetium-99m methoxyisobutylisonitrile (Tc-MIBI) parathyroid imaging by exploring the association between early uptake results (EUR), delayed uptake results (DUR), and the retention index (RI) in dual-phase Tc-MIBI parathyroid imaging and P glycoprotein (P-gp), multidrug resistance-associated protein 1 (MRP1), and glutathione S-transferase-π (GST-π) expression in hyperparathyroidism (HPT). PATIENTS AND METHODS: Preoperative dual-phase (early and delayed) Tc-MIBI imaging was performed on 74 patients undergoing parathyroidectomy for HPT...

OBJECTIVE: To determine the extent to which consensus guidelines for surgery in patients with primary hyperparathyroidism (PHPT) are followed within an academic health system. BACKGROUND: Previous studies have shown that adherence to consensus guidelines in community practice is low. METHODS: Adults with biochemically confirmed PHPT who received primary care within an academic health system were identified from 2005 to 2015. Multivariable logistic regression was used to analyze predictors of parathyroidectomy (PTx)...

A normal serum calcium level is 8 to 10 mg/dL. The diagnosis of hypercalcemia (ie, levels 10.5 mg/dL or greater) should be confirmed with an albumin-adjusted or ionized calcium level. The two most common causes of hypercalcemia are hyperparathyroidism and malignancy. Drugs, notably lithium and thiazide diuretics, also can cause hypercalcemia. Patients with severe or symptomatic hypercalcemia should be treated initially with hydration to decrease calcium levels. The evaluation should include a parathyroid hormone (PTH) level...

AIMS: This study explored the use of a value-based pricing approach for the new calcimimetic etelcalcetide indicated for the treatment of secondary hyperparathyroidism (SHPT) in patients receiving hemodialysis. It used the US payer perspective and applied the cost-effectiveness framework. Because etelcalcetide is an intravenous therapy that can be titrated for individual patients, and because its utilization is yet to be assessed in real world settings, a range of plausible doses were estimated for etelcalcetide to define a range of prices...

Importance: Parathyroid 4-dimensional computed tomographic scans (4D-CTs) have emerged as an accurate and cost-effective initial localization study for patients with primary hyperparathyroidism. However, potential limitations and factors affecting the accuracy of preoperative 4D-CTs remain poorly defined. Objectives: To characterize factors associated with missed parathyroid lesions on preoperative 4D-CTs and to investigate patterns of commonly observed errors. Design, Setting, and Participants: A prospectively accrued patient database was analyzed from September 1, 2011, through October 31, 2016...

RATIONALE: Given that the diagnosis of primary hyperparathyroidism (PHPT) is given at an increasingly less-symptomatic phase, and the literature data on the cardiovascular risk of patients with normocalcemic primary hyperparathyroidism (NPHPT) are controversial, the coronary calcium score (CCS), which is correlated with coronary artery disease, may be useful for clarifying the association between cardiovascular risk and NPHPT. OBJECTIVE: This research aims to describe the CCS and the clinical and laboratory variables of patients with NPHPT compared with a control group and to verify the presence of an association between NPHPT and CCS...

Calciphylaxis is a clinical syndrome of arteriolar calcification with resultant tissue necrosis, most commonly seen in patients with end-stage renal disease (ESRD) on dialysis. This condition carries a high mortality rate mainly due to infection. Helpful interventions include adequate dialytic therapy, medical management of hyperparathyroidism, hyperphosphatemia, and intravenous sodium thiosulfate therapy.

BACKGROUND: We occasionally experience cases of severe secondary hyperparathyroidism (SHPT) that require parathyroidectomy (PTX) despite undergoing short-term renal replacement therapy (RRT). Because the characteristics of such cases have never been discussed, we aimed to elucidate the pathophysiology of severe SHPT after short-term RRT by retrospectively analyzing clinical data. METHODS: A total of 1013 patients with severe SHPT underwent PTX between January 2007 and April 2016 at Nagoya Daini Red Cross Hospital...

Despite improvements in parathyroidectomy success rates, patients with persistent primary hyperparathyroidism (PHPT) after initial surgery continue to challenge clinicians. Some of the challenges are due to ectopic parathyroid adenomas, including thymic, intrathyroidal, carotid sheath and mediastinal glands, and others are because of supernumerary glands. While uncommon in PHPT, multigland disease is also an important consideration in patients requiring reoperative surgery for persistent disease. For this reason, localisation studies including sestamibi, ultrasound, CT scan and venous sampling for abnormal glands may be an essential component of the preoperative workup...

BACKGROUND: Inactivating mutations of CDC73 cause Hyperparathyroidism-Jaw Tumour syndrome (HPT-JT), Familial Isolated Hyperparathyroidism (FIHP) and sporadic parathyroid carcinoma. We conducted CDC73 mutation analysis in an HPT-JT family and confirm carrier status of the proband's daughter. METHODS: The proband had primary hyperparathyroidism (parathyroid carcinoma) and uterine leiomyomata. Her father and daughter had hyperparathyroidism (parathyroid adenoma) but no other manifestations of HPT-JT...

BACKGROUND: Elastase-1 is a proteolytic enzyme secreted by pancreatic acinar cells, and measurements of the concentration this enzyme are used to evaluate pancreatic exocrine function. We aimed to determine whether pancreatic exocrine function declines due to chronic hypercalcemia by measuring fecal elastase levels. METHODS: 75 patients with primary hyperparathyroidism (18 men and 47 women) and 30 healthy subjects (11 men and 19 women) participated in this study...

PURPOSE: Parathyroid venous sampling (PAVS) is usually reserved for patients with persistent or recurrent hyperparathyroidism after parathyroidectomy with inconclusive noninvasive imaging studies. A retrospective study was performed to evaluate the diagnostic efficacy of super-selective PAVS (SSVS) in patients needing revision neck surgery with inconclusive imaging. MATERIALS AND METHODS: Patients undergoing PAVS between 2005 and 2016 due to persistent or recurrent hyperparathyroidism following surgery were reviewed...

Multiple endocrine neoplasia type 1 is a rare autosomal inherited disorder associated with a high risk for patients to simultaneously develop tumours of the parathyroid glands, duodeno-pancreatic neuroendocrine tumors and tumors of the anterior pituitary gland. Early identification of MEN1 in patients enables presymptomatic screening of manifestations which makes timely interventions possible with the intention to prevent morbidity and mortality. Causes of death nowadays have shifted towards local or metastatic progression of malignant neuro endocrine tumors...

BACKGROUND: Microwave ablation (MWA) is an effective treatment for severe secondary hyperparathyroidism (SHPT), but it can also be used for mild-to-moderate secondary hyperparathyroidism (SHPT). In this randomised, controlled study, the efficacy of MWA in the treatment of mild-to-moderate hyperparathyroidism is investigated. MATERIALS AND METHODS: We assessed outcomes 12 months after the randomisation of 28 patients with mild-to-moderate SHPT. The subjects received either MWA plus calcitriol or calcitriol alone...

Objective: to evaluate the benefit of parathyroidectomy in patients on hemodialysis, regarding nutritional and biochemical statuses, body composition and the health-related quality of life. Methods: this is a longitudinal study involving 28 hemodialysis adult patients with severe secondary hyperparathyroidism evaluated before and one year after surgery. Inclusion criteria: parathyroid hormone levels exceeding ten times the upper normal range and end-stage renal disease in hemodialysis program...

Bone disease in long-term survivors after gastric cancer resection has received little research attention. This study aimed to investigate bone health after curative resection of gastric cancer and the consequences of high-dose vitamin D supplementation in patients with low levels of 25-(OH)-vitamin D. Disease-free patients at least 24 months after gastric cancer resection represented the study cohort. Serum markers of bone metabolism were assessed at baseline and at 3 and 12 months. Bone mineral density and presence of fractures were assessed by X-ray at baseline...
