Primary hyperparathyroidism is a common endocrine disease. The first line therapy for the disease is surgical removal of affected parathyroid gland(s). Other therapeutic options with medication are needed to be established, because many of patients with primary hyperparathyroidism have few or no symptoms and are expected to have a long life expectancy without surgery. Cinacalcet as a calcimimetic, bisphosphonates and denosumab are promising candidates for medical management of the disease. Effectiveness and efficiency of these drugs for patients with primary hyperparathyroidism is to be evaluated in comparison with surgical treatment...

Primary hyperparathyroidism(pHPT)is a frequent endocrine disease in which abnormal calcium(Ca)regulation leads to hypercalcemia. The most frequent cause of pHPT in more than 80% of patients is an adenoma, followed by hyperplasia in about 15%, and cancer in 1~5%. Although most cases of pHPT are sporadic, a few are familial(hereditary), and this is known as familial hyperparathyroidism(FHPT). Gene abnormalities that affect cyclin D1 signaling(CCND1, CDC73, CDKN1B), Wnt/β-catenin signaling(MEN1), and calcium-sensing receptor signaling(CaSR, GNA11, AP2S1)play a role in the etiology and pathogenesis of pHPT...

Parathyroid cancer is a rare endocrine malignancy, representing less than 1 % of all cases of primary hyperparathyroidism. The exact etiology of the disease remains unknown. Known risk factors include neck irradiation, end stage renal failure, genetic factors, particularly the the HPRT2/CDCT73 gene mutation. The clinical picture is often indolent, yet progressive with a trend of local invasion and metastasis formation in advanced disease. The clinical picture includes symptoms of severe and resistant hypercalcemia, requiring intensive therapy often with the need of dialysis...

Calciphylaxis (CPX) is a rare calcifying thrombotic vasculopathy responsible for painful necrotic ulcers, with a high mortality rate, and its management is often difficult. Recently, intravenous infusions of sodium thiosulfate (STS) have shown efficacy. The aim of this study was to assess the efficacy of intralesional STS (IL STS) in four patients. Our aim was to assess the efficacy of IL STS in a prospective mono-centric open study that included four patients with a biopsy-proven cutaneous CPX. Four women (55-84 years old, mean age: 71·2 years) with a uremic (n = 1) or non-uremic CPX (n = 3) and primary hyperparathyroidism induced by teriparatide or after the initiation of oral anti-vitamin K were treated by IL STS (250 mg/ml)...

OBJECTIVE: Primary hyperparathyroidism (pHPT) is characterised by increased parathyroid hormone (PTH) secretion and consequently increased plasma calcium. During the last few decades parathyroid scintigraphy (PS), is applied in almost all patients with pPHT before surgery and specifically before minimally invasive parathyroidectomy. The aim of this study was to find the best cut-off levels of total plasma calcium and intact PTH (iPTH) that correlate with positive technetium-99m-methoxy isobutyl isonitrile ((99m)Tc-MIBI) PS and with positive subtraction PS (SPS) in patients with pHPT and thus the positive diagnostic value of these PS...

A small radiolucent area in the mandible was discovered in a 58-year-old woman with no oral complaints. The patient's history included only hypertension. The lesion was considered as an inflammatory cyst and was enucleated. Three months later, a CT revealed the presence of a cyst-like lesion in the mandible with thin expanded buccal cortical plate, localized erosion, and a polylobate appearance on the lingual aspect of the cortical plate. The histological diagnosis of the lesion was central giant-cell granuloma (CGCG)...

Primary hyperparathyroidism is a condition with hypercalcemia and elevated parathyroid hormone (PTH). Typically, treating patients with such disease does not pose a problem for doctors, unless the patient is pregnant. Firstly, pregnancy may mask signs of hypercalcemia. Secondly, treatment should be applied with special care for immature fetus. If undiagnosed and untreated, it is life-threatening for the mother and the baby. The main cause of primary hyperparathyroidism is parathyroid adenoma, which should be removed surgically in second trimester...

Obesity is often associated with vitamin D deficiency and secondary hyperparathyroidism. Vitamin D supplementation typically leads to the reductions in serum parathyroid hormone (PTH) levels, as shown in normal weight individuals. Meanwhile, the dose of vitamin D supplementation for the suppression of PTH may differ in overweight and obese adults. We conducted a systematic review and meta-analysis of randomized controlled trials to determine the dose of vitamin D supplementation required to suppress PTH levels in overweight/obese individuals...

Many diseases can cause hypercalcaemia, including primary hyperparathyroidism, cancer, drugs and granulomatous diseases. A nursing home resident aged 81 years was admitted because of altered mental status. The patient did not have fever, cough, sputum or night sweat. Hypercalcaemia was identified as a cause of the consciousness disturbance. Chest radiograph showed no acute process. Laboratory workups revealed elevated serum levels of 1,25-(OH)2 vitamin D3 and positive T-spot test. Microscopic examination of the suctioned sputum identified acid-fast bacilli, which was confirmed as Mycobactrium tuberculsosis Tuberculosis should be considered as the important cause of hypercalcaemia since early diagnosis and treatment is recommended for preventing its outbreak among people with close contacts with patients...

Nephrocalcinosis is characterized by calcification of kidney parenchyma and can be caused by an increased amount of calcium, phosphate or oxalate in urinary excretion. We report a 35-year-old female with nephrocalcinosis. She had fitful steatorrhea since last year. Physical examination was normal. Analytic exams found normal renal function and ionogram. Primary hyperparathyroidism, renal tubular acidosis and sarcoidosis were excluded. Urinalysis showed mild hematuria, without proteinuria and 24-hour urine collection exhibited hyperoxaluria...

BACKGROUND: Intraoperative PTH (IOPTH) monitoring has been widely used to confirm the removal of the culprit lesion during operation. However, the true benefit of IOPTH in patients with preoperatively well-localized single adenoma has been questioned. The aim of this study was to examine how or if IOPTH changes the surgical management and outcomes in patients with only one positive or only indeterminate localization studies. METHODS: This is a retrospective review of data from a parathyroid surgery database and patient records from July 2004 to June 2014, including patients with primary hyperparathyroidism with a planned MIP by two experienced endocrine surgeons after ≥1 positive/indeterminate preoperative localization study by ultrasound and/or sestamibi...
