BACKGROUND: Hypercalcaemia may cause @entity810 . MATERIAL AND METHODS: We present and discuss two @entity1 with @entity810 caused by hypercalcaemia. RESULTS: @entity1 no. 1 was treated with too high doses of @entity560 for @entity261 . @entity1 no. 2 had been taking extremely high doses of @entity4959 for @entity158 . Volume depletion and renal vasoconstriction are the mechanisms that lead to @entity810 . Long-lasting hypercalcaemia will lead to @entity460 deposits in the kidneys ( @entity11604 ), which is known to cause @entity177 . INTERPRETATION: It is mandatory to start early treatment for serious hypercalcaemia. If treatment is started in time, the @entity177 may be reversible. Constant vigilance is essential when @entity1 are treated with @entity560 .
