1 Children's Hospital of Michigan, 5224 St. Antoine St., Detroit 2, Michigan.
Dr. C. L. Mitchell, chief of the orthopedic section at the Henry Ford Hospital, has sent me a copy of the April, 1959, number of the Bulletin of the Hospital for Special Surgery containing an article by John B. Griffin entitled, Hypervitaminosis A.
This report describes briefly three children (twins [fraternal] aged 2 years; the other 19 months) with painful limps. Each is purported to have received about 200,000 units daily of "water soluble" vitamin A from roughly 4 months of age to the first birthday. The bony changes described and illustrated are limited to cupping of the metaphyses so that the distal epiphyses of the femurs (and in one illustration, of the tibia) appear imbedded within or sunken into the substance of the diaphysis.
