The clinico-palhological features of inguinal hernia in infancy have been discussed. It is suggested that these hernias should be classified as complete and incomplete and that other terms that only give rise to confusion should be abandoned. When the sac contains fluid only it should be referred to as a fluid hernia. It has been emphasized that strangulation can and does occur during infancy. Irreducibility should be regarded in the same serious light as it is in adults and taxis should never be attempted. Treatment has been discussed and it has been pointed out that herniotomy between the ages of 3 and 6 months is desirable in the majority of cases. Fifty consecutive cases treated at the Groote Schuur Hospital have been reviewed briefly.
In the regulation of blood pressure the adrenal medulla and the thyroid -gland have antagonistic actions. On the assumption that thyroid insufficiency is the basic factor in the causation of essential hypertension, 334 cases of hypertension were treated with thyroid extract. About 70% responded favourably. Renal hypertension does not respond to thyroid treatment. The value of thyroid extract in the treatment of essential hypertension is confirmed.
