    Eighty-two boys with severe haemophilia A who spent some time at Lord Mayor Treloar College during 1973-7 were studied. All episodes of bleeding that occurred during term time were recorded, along with the number of transfusions. The bleeding frequency among these boys, most of them aged 10-17 years, increased steadily from 8,31 episodes/100 days in 1973 to 12,63 episodes/100 days in 1977. At the same time there was a steady fall in bleeding frequency with age. Altogether 24% of bleeding episodes were into the elbow joint, 22% into the knee, and 15% into the ankle. As the boys grew older the proportion of bleeding episodes in the legs declined and that in the arms increased. The overall results reflect the fact that special schools now see only the severest cases of haemophilia. The pattern of bleeding during adolescence suggests that concepts of management of arm bleeding need modifying.
