Background. Hyperparathyroidism is underdiagnosed in pregnancy, yet early diagnosis is necessary for the potentially severe sequelae of hypercalcemia for both the woman and fetus. Case. A 31-year-old, gravida 3, para 0-0-2-0 at 32 weeks and 3 days of gestation, presented with preeclampsia with severe features concomitant with acute pancreatitis and known diabetes mellitus type 2. She was stabil...

Renal failure of 4 wk duration in rats led to parathyroid enlargement, increased bone resorption, and decreased tubular reabsorption of phosphate by the remnant kidney. The degree of hyperparathyroidism was influenced by each of the three dietary factors investigated. In the first study increasing calcium intake reduced the size of the parathyroids by increasing calcium and reducing phosphate a...

OBJECTIVE To establish whether urinary and serum calcium levels are correlated in patients with primary hyperparathyroidism (PHPT) and to evaluate related factors including serum levels of parathyroid hormone (PTH) and vitamin D, age, gender and renal function. DESIGN Retrospective review on patients undergoing a parathyroidectomy for PHPT from 2000- 2008. Data collected included: age, sex, p...

Ionized calcium is critical to the maintenance of normal cardiovascular function. Recently, vasoactive properties have also been attributed to parathyroid hormone (PTH). The present study characterizes the calcium-PTH axis in the spontaneously hypertensive rat (SHR) in order to determine the effects of chronic alterations in calcium intake on the development and maintenance of hypertension in t...

A case of the 'milk alkali syndrome' associated with grossly elevated levels of amino terminal parathyroid hormone is described. The hypercalcaemia (calcium 4.09 mmol/l) and hyperparathyroidism settled on conservative measures. Factors in the milk alkali syndrome which might stimulate the release of parathyroid hormone include parathyroid gland hyperplasia secondary to suppression of ionized ca...

The aim of this study was to attempt at providing a complete picture of dynamics of selected biochemical blood parameters (parathyroid hormone, Calcium, Phosphorus, Sodium, Potassium, Chlorine and ionized calcium) around calving period in high producing dairy cattle (Holstein breed), giving new and useful information about the guidelines for the management strategies during different physiologi...

OBJECTIVE The aim of the present study was to identify a fast, efficient and low-cost method to diagnose hypoparathyroidism after total thyroidectomy. MATERIALS AND METHODS One hundred and forty medical records, which contained patients' clinical and laboratory data, were retrospectively analyzed. Patient parathyroid hormone values, which were obtained immediately following operation, were co...

The parathyroid gland secretes parathyroid hormone (PTH) which is a key element in the regulation of serum calcium. The PTH elevates serum calcium activities by regulating its action on the bones, kidneys and small intestine. The set point of PTH secretion defines the sensitivity of the parathyroid glands to calcium concentration. Secondary hyperparathyroidism (SHPT) is a common complication of...
