[Primary hyperparathyroidism--advances in diagnosis and treatment]

The primary hyperparathyroidism (PHP) is a complex of nosological symptoms associated with disturbances of calcium-phosphate equilibrium and bone metabolism, caused by excessive secretion of parathyroid hormone. In the past regarded as rare entity, today it is arousing great interest due to ever more frequent diagnosis of it in the stage of subtle psychoneurological changes or in the asymptomatic period. Untreated PHP leads to the development of a number of organ complications, and even to a life-threatening state, that is hypercalcemic crisis. Surgical operation is the treatment of choice.
