Abstract
-
Primary hypomagnesemia is a rare inherited disorder and it is considered to be due to either
a defect in the intestinal transport of magnesium or a defect in renal tubular transport. It
is important to measure the urinary excretion of magnesium to differentiate the causes of
magnesium deficiency. We report here an one-month-old female infant of primary hypomagnesemia
who presented generalized tonic-clonic seizures. She had hypomagnesemia(<1.5mg/dL) and
several seizure attacks but normal magnesium creatinine ratio in random urine and normal
magnesium excretion in 24-hour urine. Continuous oral magnesium supplementation was necessary
to avoid the recurrence of symptoms and maintain serum rnagnesium levels.
