This is a very interesting and thorough study on the comparative frequency of rickets in children of tuberculous mothers and in children of tuberculosis-free parents. In roentgenograms taken at birth of 93 infants whose mothers had tuberculosis, no instances of congenital rickets were found. Of 150 children of tuberculous parents, 50.4 per cent were later found to show signs of rickets, as compared with 48.8 per cent of 48 children whose parents were not tuberculous. Of the premature infants studied, 81 per cent of each group showed rickets. From this the authors conclude that tuberculosis in the mother does not affect the frequency of rickets in her children.
