[Hypercalcemia].

Hypercalcemia defined as serum calcium >2.62 mmol/l (10.5 mg/dl) is a relatively common clinical problem. Malignancy and primary hyperparathyroidism remain its leading causes. The clinical symptoms depend on the degree and duration of the disorder. Hypercalcemia can affect different organs or systems. The therapy involves saline hydration, loop diuretics, antiresorptive drugs (calcitonin, bisphophonates), steroids. In severe hypercalcemia hemodialysis may be necessary.
