Renal arteries of a 29-year-old hypertensive woman are described typical of fibro muscular dysplasia. Segmental stenoses of femoral, humeral and carotid arteries are associated. The histological study of one renal artery discloses a sub-adventitial fibrosis; besides there are pictures which are very close to those found during chronic intoxication with ergotamine tartrate. Patient history confirms this intoxication. Discontinuation of the ergotamine intoxication and administration of vaso-dilating substances are associated with a dramatic subjective and objective improvement of renal and peripheral arterial signs. The reversibility of the symptoms constitutes a serious clinical proof of the hypothesis of Bercquist and coll. (1971): that a prolonged arterial spasm could represent a promoting factor of arterial fibro-muscular dysplasias.

Identification of Campylobacter pylori in gastric biopsy smears.

The use of gastric biopsy imprint smears to diagnose Campylobacter pylori was compared with the use of tissue sections and cultures. Multiple gastric biopsies were taken from the mucosa of 42 patients during endoscopy. Imprint smears were prepared from the samples used to make tissue sections; other samples were used for microbiologic culture. There was a good concordance (93%) between the morphologic diagnosis of C pylori in the air-dried, Giemsa-stained smears and the tissue sections; the cytologic preparations were clearly positive in six cases (14%) whose sections contained low numbers of the organisms. There was a concordance of 83% between the combined morphologic techniques and the bacteriologic culture. Six positive cases were detected only by the morphologic techniques while one positive case was detected only by bacteriologic culture. C pylori was identified in one or more preparations of the antral biopsy specimens in 23 (55%) of the 42 cases, including 23 (74%) of the 31 cases with a final diagnosis of gastritis or ulcer. These results show the usefulness of the cytologic study of gastric biopsy smears in diagnosing C pylori infections.
