In this study, we present the case of a 5-year-old female who presented for evaluation of dehydration with labs that revealed significant hypernatremia concerning for diabetes insipidus (DI). Further evaluation revealed that she had underlying chronic malnutrition. Her diagnostic work up for DI produced some evidence consistent with DI while other data indicated otherwise, bringing up the possibility of partial DI.

Prolonged Seizure Activity Followed by Severe Hyperphosphatemia and Hypocalcemia in a Pediatric Patient.

Seizures secondary to hypocalcemia have been well documented and studied. There are various causes of hypocalcemia described in the literature, but a prolonged seizure episode leading to cell lysis, severe hyperphosphatemia, and hypocalcemia is rarely reported. We present the case of a 3-year-old male with severe hyperphosphatemia and hypocalcemia secondary to the likely presence of cell lysis from prolonged seizure activity.
