Primary hyperparathyroid

BACKGROUND: Patient-reported outcomes are measured in chronic disease states to inform intervention and management decisions while minimizing negative outcomes. We hypothesized that health-related quality of life in patients with multiple endocrine neoplasia type 2A would be worse than the general US population but similar to other chronic diseases. METHODS: Adults ≥18 years with multiple endocrine neoplasia type 2A were recruited to complete the Patient-Reported Outcomes Measurement Information System 29-item questionnaire (n = 45)...

Two pediatric patients with different causes of hyperparathyroidism are reported. First patient is a 13-year-old male with severe hypercalcemia due to left upper parathyroid gland adenoma. After successful surgery, calcium and phosphate levels normalized, but parathormone levels remained elevated. Further studies revealed a second adenoma in the right gland. The second patient is a 13-year-old female with uncommon hypercalcemia symptoms. Presence of pathogenic calcium-sensing receptor gene ( CASR ) mutation was found, resulting in diagnosis of symptomatic familial hypocalciuric hypercalcemia...

BACKGROUND: Renal replacement therapy (RRT) with regional citrate anticoagulation (RCA) is an important therapeutic approach for refractory hypercalcemia complicated with renal failure. However, RCA has the potential to induce arrhythmia caused by rapid calcium loss. We report a case of arrhythmia associated with rapid calcium loss during RCA-RRT. CASE PRESENTATION: A 51-year-old man with hypercalcemia, primary hyperparathyroidism, and acute kidney injury was treated by predilutional-RCA-hemofiltration at a rate of 4...

Parathyroid glands are the main regulator of body mineral metabolism through parathormone (PTH) actions on bone and kidney. Experimental evidence suggests that PTH may have non-classical target organs such as adipose tissue, arterial vascular wall, cardiac muscle cells, and adrenal cortex cells, where it may play a role in controlling body energy, blood pressure, and metabolism. Cardiometabolic features have been investigated in the wide spectrum of clinical parathyroid disorders, from hyperparathyroidism to pseudohypoparathyroidism and hypoparathyroidism...

Hypercalcemia due to primary or secondary hyperparathyroidism is a rare and obscure cause of acute pancreatitis. Although a rare occurrence to begin with, hyperparathyroidism commonly manifests with symptoms of hypercalcemia. Thus, it would reason that a patient might develop pancreatitis by way of hypercalcemia due to primary or secondary hyperparathyroidism. We present a case of an 88-year-old female with acute pancreatitis and only after an extensive work-up, was it determined that her severe acute pancreatitis resulted from primary hyperparathyroidism caused by a left parathyroid adenoma...

INTRODUCTION: Highly specific preoperative localizing test is required to select patients for minimally invasive parathyroidectomy (MIP) in lieu of traditional four-gland exploration. We hypothesized that Tc-99m sestamibi scan interpretation incorporating numerical measurements on the degree of asymmetrical activity from bilateral thyroid beds can be useful in localizing single adenoma for MIP. METHODS: We devised a quantitative interpretation method for Tc-99m sestamibi scan based on the numerically graded asymmetrical activity on early phase...

BACKGROUND: Thyroid uptake of technetium-99m methoxyisobutylisonitrile (99m Tc-MIBI) during parathyroid scintigraphy can be affected by various conditions. AIM: To evaluate the frequency of absent 99m Tc-MIBI uptake by the thyroid gland in the early phase of dual-phase parathyroid scintigraphy. METHODS: The early planar images of dual phase Tc99m MIBI parathyroid scintigraphy from 217 patients performed between 2014 and 2017 were retrospectively analysed...

OBJECTIVE: Hypercalcemia may induce arrhythmias. There are no data on the prevalence of arrhythmias in primary hyperparathyroidism (PHPT) in daily life. Aim of the study was to investigate both the prevalence of arrhythmias in patients with PHPT compared to controls and the impact of parathyroidectomy, evaluated by 24 hour electrocardiogram (ECG) monitoring. DESIGN: This is a randomized study. METHODS: 26 postmenopausal women with PHPT and 26 controls were enrolled...

BACKGROUND: Our retrospective review of prospectively collected data evaluated the efficacy of minimally invasive parathyroidectomy (MIP) and compared preoperative imaging modalities in a rural referral centre. METHODS: Patients with a diagnosis of primary hyperparathyroidism underwent surgeon-performed ultrasound (SUS) and technetium-99 m sestamibi (MIBI). Radiologist-performed ultrasound (RUS) was sought when the diagnosis remained in doubt. Four-dimensional computed tomography (4DCT) first replaced RUS in mid-2014, then MIBI as a frontline modality in 2015...

Gitelman syndrome(GS) is a rare autosomal recessive salt-losing tubulopathy of young adults, characterised by hypokalaemia, hypomagnesaemia, hypocalciuria and secondary hyperaldosteronism. Hypercalcaemia due to hypocalciuria in these patients is extremely rare.A 25-year-old healthy woman was referred to the Endocrinology clinic for evaluation of persistent hypokalaemia. She presented with fatigue, myalgias, cramps and paraesthesia. Her physical examination was normal. Laboratory workup revealed: K+ 2.7 mEq/L (r...

A patient with extremely high calcium level of 23.9 mg/dL (5.97 mmol/L) was admitted to our department unconscious with pathological ECG recording, demonstrating shortening of QT interval. The patient was treated by fluid resuscitation, bisphosphonates, salmon calcitonin and steroids. Haemodialysis with low calcium bath had been promptly provided with improvement of consciousness and calcium level. ECG changes disappeared. Subsequent investigations revealed hyperparathyroidism and a large parathyroid adenoma was then surgically removed...

Introduction: Brown tumors of hyperparathyroidism are locally destructive bone lesions. They are the late clinical consequence of the disease. They can occur in primary, secondary, and rarely tertiary forms. They affect usually long bones and less frequently those of the maxilla. Case Report: Our 45-year-old female patient presented with a mandibular tumor next to the first right lower molar. At first, we have chosen tooth extraction and tumor excision. When the histological report showed the giant cell tumor we suspected a metabolic bone disorder...

To investigate the impact of comorbid diseases on rheumatoid arthritis (RA) outcome.All patients diagnosed with RA since 2006, who were registered in our local Danbio registry, were included in this cohort study. Patients' demographics, serology results, and Disease Activity Score in 28 joints-C-reactive protein (DAS28-CRP) at the time of diagnosis and after 4 months of treatment initiation were collected. Patients' electronic hospital records were evaluated for a positive history of thyroid diseases, diabetes mellitus, primary hyperparathyroidism, vitamin B12 deficiency, and the presence of other diagnosed autoimmune diseases...

BACKGROUND: Parathyroid hormone (PTH) is one of the principal regulators of calcium homeostasis, crucial for normal functioning of the kidneys, bones, heart, and nervous system. Different pathologic conditions can affect serum PTH level resulting in hyperparathyroidism or hypoparathyroidism. Our study assessed the association of previously reported polymorphisms with the level of PTH (expressed in pg/mL) among individuals with different pathologic conditions affecting PTH level. METHODS: We searched Web of Science, MEDLINE, and Scopus to identify relevant articles published up to July 2017...

Robotic parathyroidectomy represents a novel surgical approach in the treatment of primary hyperparathyroidism when the parathyroid adenoma has been pre-operatively localised. It represents the "fourth generation" in the evolution of parathyroid surgery following a process of surgical evolution from cervicotomy and 4-gland exploration to a variety of minimally invasive, open and endoscopic, targeted approaches. The existing evidence (levels 2-3) supports it as a feasible and safe technique with equivalent results to targeted open parathyroidectomy for primary hyperparathyroidism in carefully selected patients...

OBJECTIVE: The main cause of primary hyperparathyroidism is a single parathyroid adenoma. Parathyroid lipoadenomas contain abundance of fat cells. Because of these histological features, they can mimic normal parathyroid tissue at the histopathologic examination and radiological imaging could be difficult to localize lipoadenomas. CLINICAL PRESENTATION: In this case report, we present three cases of functional parathyroid lipoadenomas. CONCLUSION: Preoperative imaging modalities often can't localize lipoadenoma...

Primary hyperparathyroidism is one of the most common endocrine diseases, however, it is rare in children. In most cases, it is caused by adenoma of these organs. Its most common complications include urolithiasis, nephrocalcinosis and osteoporosis. CASE REPORT: A 16-year-old patient was admitted to our Clinic because of his first-ever renal colic. The ultrasound examination revealed rightsided hydronephrosis caused by the presence of 9 mm stone in the upper part of the right ureter. In addition, the presence of 8 mm stone in the middle calyx of the left kidney was found...

BACKGROUND: The calcimimetic agent cinacalcet is effective for the management of secondary hyperparathyroidism (SHPT) in dialysis patients. Changes to reimbursement of cinacalcet in Australia provided an opportunity to assess effects of medication cessation on biochemical and clinical outcomes in dialysis patients, including changes to novel biomarkers such as calciprotein particles (CPP). CPP are nanoparticles of mineral and protein in the circulation associated with increased vascular calcification in patients with chronic kidney disease...
