In a survey of 7,044 necropsies there were 99 cases of aneurysm of the abdominal aorta and 523 cases of peptic ulceration. The incidence of peptic ulceration in the general necropsy population was 7.2% whilst in cases with aneurysm it was 22.6%. There was a significant increase in duodenal ulceration in males with abdominal aortic aneurysms. The possible causes for this increased incidence are discussed.

The histological and clinical features of a primary chemodectoma arising in the orbit are described. It is suggested that the tumour may have arisen from chemoreceptor tissue in the area of the lacrimal gland.

The aorto-iliac disobliteration technique using the LeVeen plaque cracker is described and the results in 70 patients (operated on at the Elisabeth Hospital, Sluiskil, The Netherlands), are presented. The early mortality rate for the series was 4.3%. There were two cases of haemorrhage due to adventitial damage, within two weeks of the operation. The 5 year patency rate was 100%. The LeVeen disobliteration technique is a considerable improvement in the conventional open or half closed endarterectomy. The operation is shorter, and simpler. Also it is ideally suited for combination with the retroperitoneal approach. The technique can be easily combined with disobliterations distal to the groin. The relative advantages and disadvantages of the closed disobliteration and synthetic graft methods are discussed together with the reasons why the closed disobliteration technique seems to be the method of choice in those patients without aneurysms or excessive calcification.
The efficiency of general practitioners and cytology screening programs in the Netherlands in diagnosing neoplasia by means of cervical cytology was investigated. For all age groups of women living in rural or urban areas, the general practitioners were almost twice as successful in detecting cases of cervical neoplasia. No reason could be found why the general practitioners were relatively more successful. The important role of the general practitioner and his or her ability to encourage the high-risk group of women to have early and regular smears is stressed.
