J. L. Reverdin (Congrès Francais de Chirurgie, 2 session, Paris, 1886.) This disease, following frequently in the after-history of cases of extirpation of the thyroid body, and called by Kocher, of Berne, cachexia stumpriva, was first described by Reverdin, and by him called “operative myxœdema.” His description of this disease coincides in general with the views now generally held, although we find some not unimportant deviations from Kocher’s conclusions; for instance, the latter observed the disease twenty-four times following thirty-four operations, it appearing to attack by preference those who had not attained their full development. On the other hand, R., basing his experience upon copious statistics, believes the disease is comparatively rare, following upon operations of the thyroid in only twenty-seven per cent. of cases. In his experience, it likewise preferably attacks children and young persons, but that it occasionally fails to occur after complete thyrotomy. Further, R. has observed a milder form of the disease, differing essentially from the graver type of the affection, which latter invariably tends progressively to a fatal termination. In the milder form, the disease is described as oscillating between relapses and improvement, lasting for years, cure sometimes resulting. Several cases are detailed supporting these observations. In two of these, it was supposed that the thyroid had been extirpated in toto, but it was subsequently discovered that a small portion of the gland had remained. Three cases are worthy of especial note. In these, after partial extirpation, in one the right lobe, and in two the left having been removed, an imperfect form of the disease made its appearance after several months. The characteristic signs, such as swelling of the face and limbs and hesitancy of speech and of muscular movements were absent; while the other symptoms, such as general weakness, pains in the limbs, chest, and head, greater or less loss of memory, chilly sensations, reminded one distinctly of the more complete form of the disease. In all these cases slow improvement followed. Another case is worthy of notice from the fact that, two months after the operation, the remaining lobe had so atrophied as to be scarcely distinguishable. Cases of this atrophy following partial extirpation have been observed both in Germany and in England. UPON LUXATION OF THE HEAD OF THE RADIUS FORWARD.
