Parathyroidectomy is the only curative therapy for patients with primary hyperparathyroidism. However, the incidence, correlates and consequences of parathyroidectomy for primary hyperparathyroidism across the entire US population are unknown. We evaluated temporal trends in rates of inpatient parathyroidectomy for primary hyperparathyroidism, and associated in-hospital mortality, length of sta...

The four parathyroid glands, normally located behind the four poles of the thyroid gland, secrete parathyroid hormone (PTH), which regulates extracellular calcium levels. Hyperparathyroidism, which can be primary, secondary, tertiary or quaternary, results in excess production of PTH. Excessive PTH secretion may be due to hyper-function in the glands themselves, in which case it is referred to ...

A prospective screen for hypercalcaemia in 58,053 hospital in-patients was conducted over 12 months. The incidence of hypercalcaemia was 0.6%, being transient in 19.2% of patients and sustained in the remainder. The most common causes in the sustained group were malignancy (45%) and primary hyperparathyroidism (16.5%). The incidence of primary hyperparathyroidism was 78/100,000 hospital in-pati...

Severe neonatal primary hyperparathyroidism is a very rare type of primary hyperparathyroidism in pediatrics that might present during infancy with non-specific symptoms. We report an infant who presented with a very high level of calcium, yet responding to simple medications to draw the attention to pediatricians to this disease as early diagnosis and treatment will ameliorate its devastating ...

Aetiology and pathogenesis A large number of diseases can lead to hypercalcaemia (table). In most instances the underlying cause is either primary hyperparathyroidism or malignant disease; the many other causes are rarely encountered even within specialist units. The prevalence of primary hyperparathyroidism and hypercalcaemia of malignancy varies with the population sampled. In ambulant subjec...

Hyperparathyroidism is a condition which can be primary, secondary or tertiary and is characterized by increased calcium levels, low phosphate levels, and elevated parathyroid hormone (PTH) levels. Primary hyperthyroidism can cause severe bone resorption leading to bone pains and pathological fracture. We present the case of a patient with severe primary hyperparathyroidism with an atraumatic f...
