Figure 6-5. Tumoral calcinosis resulting from soft tissue calcifications.

11 mg/dL, or parathyroid gland size > 1 cm in diameter by ultrasonographic examination (Table 6-4).1516 Criteria for resistance to medical treatment are hypercalcemia, uncontrollable hypertension, progressive ectopic calcification, severe symptoms, severe skeletal deformity, progressive bone loss, cal-ciphylaxis, and anemia resistant to erythropoietin. Because skeletal deformity, vessel calcification, and the remarkable reduction of bone content in severely advanced renal HPT are irreversible, it is essential to perform surgery early. Surgery is also recommended if parathyroid hyperplasia progresses to nodular hyperplasia; set points for PTH release in the latter are shifted toward significantly higher calcium levels.17 Preoperative tumor localization studies are not cost effective in patients with secondary HPT because of a significant number of both false-positive and false-negative results and because virtually all patients have multiple gland disease.18

Blood Pressure Health

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
