A rare and reversible case of heart failure-Hypocalcemia due to hypoparathyroidism.

Physicians should look more carefully for the potential reversible causes of acute heart failure, namely hypoparathyroidism. The recovery of left ventricular function with the treatment of hypoparathyroidism underlines the importance of calcium and the reversibility of this type of cardiomyopathy.

A reversible case of rapidly progressive dementia-Hypercalcemia due to hyperparathyroidism.

With an increasingly aging population, it is of extreme importance to exclude potentially reversible dementias, such as hyperparathyroidism with hypercalcemia, in the differential diagnosis of a rapidly progressive dementia. According to literature, this entity is undervalued and it is highly relevant to be aware of it.
