BACKGROUND: Parathyroid water-clear cell hyperplasia (WCCH) and water-clear cell adenoma (WCCA) are rare causes of primary hyperparathyroidism. The frequency of WCCH seems to be less than 1% of all primary hyperplasia. CASE PRESENTATION: We report a 53-year-old woman with a large unilateral water clear cell parathyroid hyperplasia associated with primary hyperparathyroidism and severe osteoporosis. Ultrasonography showed a 5.4 cm multilobulated hypoechoic well defined mass localized in the lower half of the left thyroid lobe...

REVIEW
Marcella D Walker, Shonni J Silverberg
In this Review, we describe the pathogenesis, diagnosis and management of primary hyperparathyroidism (PHPT), with a focus on recent advances in the field. PHPT is a common endocrine disorder that is characterized by hypercalcaemia and elevated or inappropriately normal serum levels of parathyroid hormone. Most often, the presentation of PHPT is asymptomatic in regions of the world where serum levels of calcium are routinely measured. In addition to mild hypercalcaemia, PHPT can manifest with osteoporosis and hypercalciuria as well as with vertebral fractures and nephrolithiasis, both of which can be asymptomatic...

Genetic association studies hinge on definite clinical case definitions of the disease of interest. This is why more penetrant mutations were overrepresented in early multiple endocrine neoplasia 2 (MEN2) studies, whereas less penetrant mutations went underrepresented. Enrichment of genetic association studies with advanced disease may produce a flawed understanding of disease evolution, precipitating far-reaching surgical strategies like bilateral total adrenalectomy and 4-gland parathyroidectomy in MEN2. The insight into the natural course of the disease gleaned over the past 25 years caused a paradigm shift in MEN2: from the removal of target organs at the expense of greater operative morbidity to close biochemical surveillance and targeted resection of adrenal tumors and hyperplastic parathyroid glands...

BACKGROUND: Primary hyperparathyroidism (PHPT) is one of the causes of osteoporosis and is known to increase the fracture risk of bone. However, multiple vertebral compression fracture due to PHPT is extremely rare. CASE DESCRIPTION: A case of acute multiple vertebral compression fracture in a patient with PHPT is described. The fracture occurred suddenly without trauma. The patient had a low T-score (-4.4), and serum hyper-calcemia and phosphatemia were evident...

BACKGROUND: Hyperparathyroidism is a common endocrine disorder. Parathyroidectomy is indicated for primary and tertiary hyperparathyroidism. Parathyroid adenoma is the cause in close to 85% of cases of primary hyperparathyroidism. METHOD: An audit based on histopathology records of patients who had parathyroidectomy from January 2011 to December 2015 in academic hospitals linked to Wits was conducted. Data collected included patients' demographics and histopathological findings...

Over the last years, the knowledge of MEN2 and non MEN2 familial forms of pheochromocytoma (PHEO) has increased. In MEN2, PHEO is the second most frequent disease: the penetrance and age at diagnosis depend on the mutation of RET. Given the prevalence of bilateral PHEO (50% by age 50), adrenal sparing surgery, aimed at sparing a part of the adrenal cortex to avoid adrenal insufficiency, should be systematically considered in patients with bilateral PHEO. Non MEN2 familial forms of PHEO now include more than 20 genes: however, only small phenotypic series have been reported, suggesting that phenotypic features of isolated hereditary PHEO must be better explored, and follow-up series are needed to better understand the outcome of patients carrying mutations of these genes...

OBJECTIVE: To determine whether pre-operative serum 25-hydroxyvitamin D has an impact on post-operative parathyroid hormone and serum calcium levels in patients undergoing total thyroidectomy for benign goitre. METHODS: This single-centre, retrospective study comprised 246 unselected surgical patients who had undergone total thyroidectomy for bilateral, benign, multinodular goitre. The correlation between pre-operative serum 25-hydroxyvitamin D and post-operative serum parathyroid hormone and serum calcium was studied to determine whether low pre-operative serum 25-hydroxyvitamin D was predictive of post-operative hypocalcaemia...

Secondary hyperparathyroidism (SHPT) occurs in patients with chronic renal failure complicated with renal bone disease and soft tissue/vascular calcification. In dialysis patients with severe SHPT, medical treatment may fail and parathyroidectomy (PTX) is indicated for definitive treatment. Severe hypocalcemia from hungry bone disease or postoperative hypoparathyroidism may occur during the postoperative period. We report here a case of severe SHPT in a hemodialysis patient treated with phosphate binders, calcitriol, and calcimimetics but who still required PTX...

Data on cardiovascular disease in primary hyperparathyroidism (PHPT) are controversial; indeed, at present, cardiovascular involvement is not included among the criteria needed for parathyroidectomy. Aim of this narrative review is to analyze the available literature in an effort to better characterize cardiovascular involvement in PHPT. Due to physiological effects of both parathyroid hormone (PTH) and calcium on cardiomyocyte, cardiac conduction system, smooth vascular, endothelial and pancreatic beta cells, a number of data have been published regarding associations between symptomatic and mild PHPT with hypertension, arrhythmias, endothelial dysfunction (an early marker of atherosclerosis), glucose metabolism impairment and metabolic syndrome...

BACKGROUND: Thyroid abnormalities have been found intraoperatively during parathyroidectomy and have resulted in concomitant thyroidectomy. The identification of concomitant disease is important prior to primary operation in order to minimize reoperations. This study investigates the incidence of concomitant primary hyperparathyroidism (PHPT) and thyroid nodular disease in patients undergoing thyroidectomy or parathyroidectomy. METHODS: We performed a retrospective review of prospectively gathered data for 621 patients who underwent thyroidectomy, parathyroidectomy, or both at Tulane Medical Center...

Introduction Involvement of the bone is common in primary hyperparathyroidism. The aim of the study was to assess bone turnover markers in response to surgery for primary hyperparathyroidism. Methods This was a retrospective study of patients diagnosed and treated for parathyroid disease between 2005 and 2012. Interventions studied were surgery and medical treatment. The main outcome measures studied were serum levels of calcium, intact parathyroid hormone (iPTH), bone-specific alkaline phosphatase, N-terminal cross-linking propeptide of type 1 procollagen (P1NP) and C-terminal cross-linking telopeptides of type I collagen (CTX), both pre- and postoperatively at 6 months and 1 year; bone mineral density (at the spine and hip assessed by dual-energy x-ray absorptiometry after 1 year of treatment...

BACKGROUND: Total parathyroidectomy (tPTX) and total parathyroidectomy with autotransplantation (tPTX + AT) are effective and inexpensive treatments for secondary hyperparathyroidism (sHPT), but we do not know which one is the optimal approach. Therefore, we undertook a meta-analysis to compare the safety and efficacy of these two surgical procedures. METHODOLOGY: Studies published in English on PubMed, Embase and the Cochrane Library from inception to 27 September 2016 were searched systematically...

Total parathyroidectomy (PTX) can be used to treat secondary hyperparathyroidism (SHPT) in uremic patients, relieving the patient's osteolytic destruction. Complete resection of bilateral parathyroid glands is key to successful operation. Recently, 2 patients successfully received surgical treatment, in which carbon nanoparticles suspension injection were used. With the help of carbon nanoparticles suspension injection, all of the 4 hyperplastic parathyroid glands were found successfully. The parathyroid hormone(PTH) was significantly decreased after operations and the clinical symptoms were relieved simultaneously...

We aimed to demonstrate the role of SPECT/CT in preoperative localization of parathyroid lesions in patients with hyperparathyroidism who had technetium-99m (Tc-99m) methoxyisobutylisonitrile (MIBI) dual-phase parathyroid scintigraphy. We evaluated retrospectively the scintigraphic data of 103 patients who had parathyroidectomy after Tc-99m MIBI dual-phase parathyroid scintigraphy with SPECT/CT. The planar and SPECT/CT images were evaluated separately to determine their efficacy in localizing parathyroid lesions...

Accurate localization of parathyroid adenomas allows for minimally invasive parathyroidectomy. This results in a shorter length of stay and increased patient satisfaction. Preoperative Technetium (99mTc) sestamibi scans accurately localize parathyroid adenomas in 70 to 85 per cent of cases. If a patient has a negative scan, it is logical to believe that with a preoperative sestamibi injection, the gamma probe may fail to help find an adenoma. We hypothesized that the gamma probe would not be useful intraoperatively for patients with primary hyperparathyroidism (PHPTH) and a negative sestamibi scan...

Parathyroid carcinoma is a very rare malignant tumor of the parathyroid gland. Clinically, this cancer is characterized by the presence of severe primary hyperparathyroidism. Diagnosis is based on histological examination but is not always easy. Surgery is the treatment of choice. We report the case of a 59-year old woman with a personal history of arterial hypertension and of recurrent renal lithiasis, presenting with diffuse bone pain associated with asthenia. Neck examination showed hard basi-cervical swelling with nonpalpable lower edge...

The detection of all glands during total parathyroidectomy (TPTX) in secondary hyperparathyroidism (SHPT) patients is often difficult due to their variability in number and location. The objective of this study was to evaluate the feasibility of near-infrared fluorescence (NIRF) imaging using indocyanine green (ICG) for intraoperative parathyroid gland (PTG) localization in SHPT patients. Twenty-nine patients with SHPT were divided into two groups with or without intraoperative NIRF imaging. ICG was administered in patients undergoing intraoperative imaging, and the fluorescence of PTGs was assessed...

OBJECTIVE: Thyroidectomy is a very common surgical procedure. Regardless of surgeon experience, incidental parathyroidectomy is a complication of thyroidectomy. The aim of this study was to identify the clinical course of incidental parathyroidectomies after thyroidectomy. METHODS: Patients who underwent thyroidectomy between January 2010 and June 2014 were evaluated retrospectively. Pathology reports were reviewed for the presence of parathyroid tissue in the thyroidectomy pathology specimens...
