Occult Parathyroid Lesions on ^99mTc-Sestamibi Scintigraphy: Morphometric, Histopathological and Anatomical Determinants of Detection [PDF]

Biomedicines
Background: Accurate preoperative localization of hyperfunctioning parathyroid glands remains challenging, particularly in secondary hyperparathyroidism where multiglandular disease may compromise scintigraphic performance.

Mechanism of calcitriol regulating parathyroid cells in secondary hyperparathyroidism

Frontiers in Pharmacology, 2022
A common consequence of chronic renal disease is secondary hyperparathyroidism (SHPT) and is closely related to the mortality and morbidity of uremia patients.

Hypercalciuria and hyperparathyroidism — is there always a connection?

Ожирение и метаболизм, 2022
Hypercalciuria is a pathological condition characterized by an excess of daily calcium excretion. A high concentration of urine calcium can initiate stone formation. There are several types of hypercalciuria, each requires an individual approach.

Pathogenesis of secondary hyperparathyroidism [PDF]

Nephrology Dialysis Transplantation, 1994
The past 20 years has witnessed a dramatic improvement in our understanding of the factors involved in the pathogenesis of secondary hyperparathyroidism in chronic renal insufficiency. The major causes are retention of phosphorus, relatively low levels of serum calcium, and decreased 1,25-(OH)2D3 (calcitriol) levels.

Pathogenesis of Secondary Hyperparathyroidism [PDF]

The International Journal of Artificial Organs, 2009
Chronic renal failure is the primary cause of secondary hyperparathyroidism (SHPT). Patients with mineral metabolism disorders commonly present with low serum calcium levels, hyperphosphatemia, and calcitriol deficiency. In normal renal function subjects, parathyroid cells have a low turnover and rarely undergo mitoses.

Disputable Issues of Etiology and Pathogenesis of Tertiary Hyperparathyroidism

Acta Biomedica Scientifica, 2019
Hyperparathyroidism is a clinical and laboratory syndrome characterized by high production of the chief cells of the parathyroid hormone, a calcium-phosphorus metabolism disorder and the organ failure (kidneys, bone tissue).There are primary, secondary ...

Secondary Hyperparathyroidism in Osteomalacia [PDF]

BMJ, 1970
Twenty-one patients with histologically proved osteomalacia from various causes were investigated for biochemical and radiological evidence of osteomalacia and secondary hyperparathyroidism. Among the 15 who maintained a normal serum calcium, seven had a raised phosphate excretion index, seven had a raised serum alkaline phosphatase, and six had ...

Recent advances in understanding and managing secondary hyperparathyroidism in chronic kidney disease [version 1; peer review: 3 approved]

F1000Research, 2020
Secondary hyperparathyroidism is a complex pathology that develops as chronic kidney disease progresses. The retention of phosphorus and the reductions in calcium and vitamin D levels stimulate the synthesis and secretion of parathyroid hormone as well ...
