Pseudohipoparatiroidismo neonatal transitorio

We present the case of a preterm neonate of 36 weeks of gestational age, who was born via cesarean section due to severe preeclampsia and fetal macrosomy, managed in neonatal intensive therapy by transient tachypnea complicated with pulmonary hypertension, with ventilatory, sedation, relaxation and inotropic support, with. On the sixth day of life he presents generalized tonic seizures that subside with the use of anticonvulsants, but severe electrolyte alterations are detected (hypocalcemia, hypomagnesemia and hyperphosphoremia ). Electrolyte improvement is achieved but when corrections are stopped reappear electrolyte disorders despite maintaining adecuate contributions with high levels of paratohormone (PTH), confirming the diagnosis of transient neonatal pseudohypoparathyroidism, secondary to the use of medications.
