Neonatal hyperparathyroidism. Conservative treatment with intravenous and oral rehydration solutions.

A neonate with primary hyperparathyroidism was successfully managed by conservative medical treatment. This treatment consisted of intravenous saline load, followed by oral rehydration solutions containing between 60-90 mmol/l of sodium. The combined administration of sodium and diuretics maintained normal levels of serum calcium. Similar cases were previously treated by parathyroidectomy with or without autotransplantation. In selected patients, medical treatment should be considered as the initial approach in mild neonatal hyperparathyroidism. It poses no specific risks and offers an alternative to surgical intervention.
