BACKGROUND: Non-functioning parathyroid carcinoma is a rare disease that is difficult to distinguish from other diseases based on the lack of hyperparathyroidism. This is a report of non-functioning parathyroid carcinoma diagnosed by reverse transcription polymerase chain reaction (RT-PCR) targeting parathyroid hormone (PTH) messenger RNA. CASE PRESENTATION: The patient is a 67-year-old male who visited our hospital for the chief complaint of hoarseness. A 5-cm mass was observed in the right lobe of the thyroid gland, and poorly differentiated thyroid carcinoma was suspected according to the fine-needle biopsy results...

Background Vitamin D deficiency represents a global health problem, affecting children and adolescents worldwide. Objects To confirm that vitamin D deficiency can present as a spectrum of clinical pictures. Methods We diagnosed nutritional rickets in a 10-month-old infant of Senegal origin with several risk factors for vitamin D deficiency. As many of these factors affected also his cohabitant relatives, we evaluate infant's family members (mother and 4 brothers) looking for other vitamin D deficiency-related comorbidities...

Primary hyperparathyroidism revealed by thoracic spine brown tumor and peptic ulcer bleeding is rare. We presented a case of 33-year-old male patient who was admitted with paraplegia. Thoracic spine magnetic resonance imaging (MRI) showed extradural lesion at T4 level. He underwent surgical decompression in T4. According to histopathologic finding and elevated serum parathormone (PTH) and hypercalcemia (total serum calcium 12.1 mg/dL), the diagnosis of brown tumor was down. Ultrasonography of his neck showed a well-defined lesion of 26 × 14 × 6 mm...

Pulse granuloma is a rare, foreign body inflammatory reaction that occurs mainly in the oral cavity. It is exceedingly rare elsewhere, with only isolated cases described in the literature. We report the case of a 79-year-old woman with a history of normocalcemic hyperparathyroidism who presented to our hospital with a painful 4-cm lump in the upper quadrants-upper outer quadrant of her left breast. The clinical and radiological (BIRADS-5) findings were indicative of a malignant lesion. However, core needle biopsy revealed features simulating hyaline ring granuloma (pulse granuloma-like)...

BACKGROUND: Hypercalcemic crisis (HC) is a potentially life-threatening manifestation of primary hyperparathyroidism (PHPT). This study aimed to identify patients with PHPT at greatest risk for developing HC. METHODS: This retrospective cohort study included patients with a preoperative calcium of at least 12 mg/dL undergoing initial parathyroidectomy for PHPT from 11/2000 to 03/2016. We compared those with HC, defined as needing hospitalization for hypercalcemia, to those without HC...

The effects of PA21, a novel iron-based and non-calcium-based phosphate binder, on hyperphosphatemia and its accompanying bone abnormality in chronic kidney disease-mineral and bone disorder (CKD-MBD) were evaluated. Rats with adenine-induced chronic renal failure (CRF) were prepared by feeding them an adenine-containing diet for four weeks. They were also freely fed a diet that contained PA21 (0.5, 1.5, and 5%), sevelamer hydrochloride (0.6 and 2%) or lanthanum carbonate hydrate (0.6 and 2%) for four weeks...

INTRODUCTION: Primary hyperparathyroidism is associated with a cluster of cardiovascular manifestations, including hypertension, leading to increased cardiovascular risk. PURPOSE: The aim of our study was to investigate the ambulatory blood pressure monitoring-derived short-term blood pressure variability in patients with primary hyperparathyroidism, in comparison with patients with essential hypertension and normotensive controls. METHODS: Twenty-five patients with primary hyperparathyroidism (7 normotensive,18 hypertensive) underwent ambulatory blood pressure monitoring at diagnosis, and fifteen out of them were re-evaluated after parathyroidectomy...

BACKGROUND: Hyperparathyroidism is common in critical illness. Intact parathyroid hormone has a half-life of 3 to 5 minutes due to rapid clearance by the liver, kidneys, and bone. In hemorrhagic shock, decreased clearance may occur, thus making parathyroid hormone a potential early marker for hypoperfusion. We hypothesized that early hyperparathyroidism predicts mortality and transfusion in trauma patients. METHODS: A prospective observational study was performed at a Level 1 trauma center in consecutive adult patients receiving the highest level of trauma team activation...

The phosphate and potassium control is indispensable to dominate the secondary hyperparathyroidism and reduce cardiovascular mortality in dialysis patients. Most of them receive only theoretical nutritional information. We therefore organized a cooking workshop for dialysis patients, with a multidisciplinary team consisting of nurses, nephrologists, a dietitian and a professional chef, to directly teach the patients and their families how to realize a low phosphorus and potassium menu, assessing the proper use of phosphate binders, and blood tests at baseline and at three and six months...

A cortical lesion of the tibial diaphysis in a young patient poses a diagnostic challenge to the clinician. Brown tumors, although not very common, may mimic malignancies on radiographs. Brown tumors are destructive lytic lesions of the bone due to increased osteoclastic activity and fibroblastic proliferation in patients with uncontrolled hyperparathyroidism (HPT). They occur after primary or secondary HPT due to renal failure but very rarely due to vitamin D deficiency. We report a rare case of a brown tumor of tibial diaphyses in a young female patient mimicking a locally aggressive tumor with secondary HPT due to a severe vitamin D deficiency...

PURPOSE: As the world's population ages, the incidence of chronic kidney disease (CKD) is growing. There is ongoing debate regarding whether high levels of parathyroid hormone (PTH) would be more common in elderly than young patients, and which factors are driven the risk of secondary hyperparathyroidism (SHPT), independent of renal function. METHODS: Elderly patients (age ≥ 65 years, N = 518) were compared to a 1:1 sex- and estimated glomerular filtration rate (eGFR)-matched sample of young patients (age < 65 years), in a cross-sectional analysis...

Inactivating mutations of the multiple endocrine neoplasia 1 (MEN1) gene cause MEN1 syndrome, characterized by primary hyperparathyroidism (pHPT), and parathyroid and gastro-entero-pancreatic pituitary tumors. At present, only 14 cases of malignant parathyroid tumor have been associated with the syndrome, with 6 cases carrying an inactivating mutation of the MEN1 gene. The present study presents the case of a 48-year-old female who presented with multigland pHPT and multiple pancreatic lesions. The patient underwent surgery several times for the excision of parathyroid hyperplasia, carcinoma and adenoma...

Parathyroid carcinoma is a very rare malignancy responsible for 0.4 to 5.2% of hyperparathyroidism. Clinical diagnosis is difficult and treatment should be codified. Surgery is the only curative treatment. We report the case of a female patient treated for malignancy-associated hypercalcemia revealing parathyroid carcinoma. The patient underwent surgery; after three months she developed lymphatic recurrence. Given the absence of other secondary involvement, bilateral lymph node dissection followed by chemotherapy was performed...

The chloride/phosphate ratio (Cl/PO4) has been suggested to have a role in primary hyperparathyroidism (PHPT), but the associations between Cl/PO4 combined with ALP level and PHPT has not been well-studied. Our aim was to investigate the predictive value of combination Cl/PO4 with ALP for PHPT. A cross-sectional retrospective analysis was conducted to examine 172 patients diagnosed with PHPT categorized into two groups: normocalcaemic primary hyperparathyroidism (NPHPT) group and hypercalcaemia PHPT group. We found that Cl/PO4 levels and ALP levels in the NPHPT and hypercalcaemia PHPT group were both significantly higher than normal controls...

Claudins constitute the major component of tight junctions and regulate paracellular permeability of epithelia. Claudin-10 occurs in two major isoforms that form paracellular channels with ion selectivity. We report on two families segregating an autosomal recessive disorder characterized by generalized anhidrosis, severe heat intolerance and mild kidney failure. All affected individuals carry a rare homozygous missense mutation c.144C>G, p.(N48K) specific for the claudin-10b isoform. Immunostaining of sweat glands from patients suggested that the disease is associated with reduced levels of claudin-10b in the plasma membranes and in canaliculi of the secretory portion...

We hypothesized that adaptation to calcium supply demands of pregnancy and lactation do not require calcitriol. Adult Cyp27b1 null mice lack calcitriol and have hypocalcemia, hypophosphatemia, and rickets. We studied wild-type (WT) and null sister pairs raised on a calcium, phosphorus and lactose-enriched "rescue" diet that prevents hypocalcemia and rickets. Bone mineral content (BMC) increased >30% in pregnant nulls, declined 30% during lactation, and increased 30% by 4 weeks post-weaning. WT showed less marked changes...
