[Neonatal hypocalcemia in 2 twins revealing maternal hyperparathyroidism. A review of the literature].

The authors report the case of dizygotic twins suffering from transitory neonatal hypoparathyroidy and leading to the diagnosis of maternal hyperparathyroidy. The differences of clinical and biological symptomatology between these twins suggest individual variations in response to phosphocalcic disorders of the mother. A review of literature find 31 other cases. This study emphasize the aggravation by the mild hypomagnesemia frequently associated, the usual severity of initial clinical symptomatology in contrast with a good neurologic outcome, the diagnosis of maternal hyperparathyroidy.
