Preliminary investigations on superficial structures show that contrast-enhanced ultrasonography may prove useful for assessing superficial lymph nodes (Rubaltelli et al. 2004), thyroid and parathyroid disease (Cosgrove 2004), muscle and joint pathologies (Krix et al. 2005 Weber et al. 2006), and breast masses (Cassano et al. 2006). 

In six cases of hthium-associated hyperparathyroidism, four had parathyroid adenomas [67, 68 ]. The authors suggested that lithium can help uncover pre-existing parathyroid disease, although there does appear to be an increased incidence of multiglandular or multiadenomatous disease in patients taking lithium. Surgical treatment is often curative when adenomas are discovered. When hypercalcemia persists, cinacalcet, a calcimimetic can be used effectively. 

Pseudohypoparathyroidism is characterized by end-organ resistance to parathyroid hormone (98,108). This disease takes various forms, including Albright s hereditary osteodystrophy, which has unusual physical features and a generalized resistance to G-protein-linked hormones that function through cAMP as a second messenger. This defect is associated with a deficiency in the levels of the a-subunit of (109). Because this defect may be generalized, such patients also have olfactory dysfunction (110).

Secondary hyperparathyroidism Increased secretion of parathyroid hormone from the parathyroid glands caused by hyperphosphatemia, hypocalcemia, and vitamin D deficiency that result from decreased kidney function. It can lead to bone disease (renal osteodystrophy). 

The answer is c. (Hardman, p 15230 Administration of intravenous CaG would immediately correct the tetany that might occur in a patient in whom a thyroidectomy was recently performed. Parathyroid hormone would act more slowly but could be given for its future stabilizing effect. Long-term control of a patient after a thyroidectomy can be obtained with vitamin D and dietary therapy Calcitonin is a hypocalcemic antagonist of parathyroid hormone. Plicamycin (mithramycin) is used to treat Paget s disease and hypercalcemia. The dose employed is about one-tenth the amount used for plicamycin s cytotoxic action. 

Calcium-phosphorus balance is mediated through a complex interplay of hormones and their effects on bone, GI tract, kidney, and parathyroid gland. As kidney disease progresses, renal activation of vitamin D is impaired, which reduces gut absorption of calcium. Low blood calcium concentration stimulates secretion of parathyroid hormone (PTH). As renal function declines, serum calcium balance can be maintained only at the expense of increased bone resorption, ultimately resulting in renal osteodystrophy (ROD) (Fig. 76-7).

The mechanism of G a disease may resnlt from insnfficient parathyroid hormone-related peptide signaling by the parathyroid hormone receptor 1 (PTHRl) in chondrocytes. This deficiency may inhibit the differentiation of chondrocytes within the endochondral growth plate (88,89). A variety of parathyroid hormone abnormalities can result.

Vitamin D is really a small family of closely related molecnles that prevent the bone disease rickets in children and osteomalacia in adnlts. In both cases, inadeqnate mineralization of bone results in bone deformation and weakness. Calcinm, Ca +, homeostasis is one goal of vitamin D activity, a goal it shares with parathyroid hormone and calcitonin. Calcium is intimately involved in bone mineralization and distnrbances of calcium levels in the blood can resnlt in inadeqnate bone mineralization or excessive calcification of other tissues.
