This was afour-month old female infant with respiratory distress and acuteheart failure. The cause of her cardiac failure was dilatedcardiomyopathy. Concomitant community acquired pneumoniawas diagnosed on chest X ray. Despite treatment, the infant'sclinical condition worsened. The mother was found to be house-bound, dark skinned and veiled while going outside of home.Laboratory studies revealed hypomagnesaemia and hypocalcaemia.The vitamin D levels of both the infant and the mother were foundto be low.
