[Hypoparathyroidism and pseudohypoparathyroidism. New aspects of the pathogenesis, diagnosis and therapy].

Recent elucidations of normal and disturbed parathyroid secretion and action have provided a basis for the understanding of general principles of endocrinology. Advanced laboratory methods and simplified study protocols have improved the diagnosis of hypoparathyroidism and pseudohypoparathyroidism, the most important feature of which is chronic hypocalcemia. The knowledge of these disorders is of great importance to the pediatrician since they occur in childhood, and the consequences of prolonged misdiagnosis and inadequate treatment may be serious.
