    Notes: Abstract We describe two asymptomatic newborns with nutritional vitamin B12 deficiency in whom increased urinary methylmalonic acid was detected by routine neonatal screening at 3 weeks of age. Both infants were exclusively breast-fed. One mother suffered from pernicious anaemia, and the other was a strict vegetarian. Both mothers had no clinical or haematological abnormality, aside from a borderline mean corpuscular volume for the vegetarian mother. This report illustrates the early appearance of functional vitamin B12 deficiency in breastfed infants of vitamin B12-depleted mothers. It also demonstrates that urinary methylmalonic acid measurement is a sensitive indicator of tissue vitamin B12 deficiency.

    1,25-Dihydroxyvitamin D-related hypercalcemia in lymphoma: Two case reports (1990)

    Notes: Summary We report two patients with non-Hodgkin's lymphoma in whom hypercalcemia and elevated 1,25 dihydroxyvitamin D (1,25-(OH)2D3) levels developed in the absence of any lytic bone lesions. Hypercalcemia responded only transiently to glucocorticoids which were ill tolerated. Intravenous APD administration was needed to circumvene hypercalcemia. Humoral hypercalcemia of malignancy is discussed. Our cases confirm that hypercalcemia associated with elevated 1,25-(OH)2D3 may occur in malignant lymphoma.
