in all his varicose-vein patients; and he reports that in a seventh of all cases (a rather higher proportion than that mentioned by other investigators 45 -) this vein was abnormal. Moreover, as more and more of these veins are explored, " two other features are emerging: first, because of the variability of its termination, there may be difficulty in exposing its ending, except with a large incision; and second, in arteries in cases of lung disease associated with finger some patients, after it has been divided flush at its clubbing. In patients with finger clubbing differential union with the popliteal vein, and its trunk stripped out catheterisation of lobar branches of the pulmonary artery at the ankle, considerable varices remain ".

Annotations BEDS FOR CONFINEMENT
IN London many women who are told to have their babies in hospital are also told that no bed can be booked for them in advance. With hospitals so hard-pressed, this arrangement is understandable; but it is also intolerable. Repeatedly the Emergency Bed Service has drawn attention to the plight of the woman in labour for whom a bed -somewhere-has to be found at the last moment; and on p. 398 Dr. Abercrombie shows again that this is happening more often-not less often as one would expect. Far from being just an occasional administrative accident, it seems to be accepted as something normal and inevitable. Of course it is not inevitable at all; and there are at least three possible ways of avoiding it that need to be considered by obstetricians, midwives, and administrators - jointly determined on effective action. The first is to find more beds. Difficult though this may sound, it should not be dismissed out of hand. If the demand were really accepted as a matter of urgency, old houses in some areas could be rapidly transformed into maternity homes for " normal cases ", staffed by midwives and general practitioners genuinely interested in obstetrics. Secondly, the conditions on which a woman qualifies for a hospital bed could be made stricter. This again is difficult, because obstetrically the list of indications for admission grows . ever longer, and the circumstances of many homes make them unsuitable for confinements. Nevertheless some: hospitals, feeling that only the best is good enough for. their own patients, are inclined to admit women whose claims to hospital confinement are tenuous; and therer may be room for a little economy here. What would transform the whole situation, however, would be a change of attitude toward the use of hospitals for " lying in ". After a normal, or even a moderatelyy abnormal, labour there is no need for the mother to stayv in hospital for ten or twelve days. Though the advantages ,

ANxioUs to encourage the introduction of the preventive aspects of medicine at an early stage into the undergraduate curriculum, the World Health Organisation has set inquiries in motion into how this may be achieved. Last year a study group explored the possibilities in physiology, and now an expert committee has reported2 on its deliberations into what can be done in this direction in the teaching of pathology. The committee held that the presentation of pathology as an undergraduate subject should not be confined to any single year but should be spread over the greater part of the entire curriculum. By ample treatment of general and experimental pathology, the teacher could lay a proper foundation for the two fundamental studies of aetiology and pathogenesis, on a proper understanding of which the scientific application of preventive measures depended. Pathology should form part of a course which was closely integrated with microbiology, radiobiology, and immunology on the one hand, and with clinical medicine and surgery on the other. In the committee’s view the teaching of the preventive aspects of pathology gained much if it was depicted against a historical background of concurrent social and medical advances. Such illustrations could not fail to impress the student with the possibilities inherent in a preventive approach. Although modern pathology now had a very broad scientific basis, its morphological aspects still retained, the report declares, a central position. A comprehensive necropsy service made an invaluable contribution to the health of any community; and the postmortem examination was one of the most appropriate stages in the medical course for the inculcation of ideas of prevention in the minds of both clinicians and students. For these and other reasons, the development of an effective necropsy service should be encouraged in all countries as an adjunct to both medical teaching and practice. The importance of collaboration between pathologists and epidemiologists was one of the committee’s main points. In time, social changes in many countries, especially those now relatively undeveloped, would 1. FitzGerald, T. B. Lancet, 1959, i, 403; see also 1959, i. 397. 2.
