Oscillotonometry using Dinamap machine was investigated for the measurement of ankle and brachial blood pressures in our vascular practice. It was validated by comparison with intra-arterial pressure measured by transducer. Systolic ankle and brachial pressures in 43 patients were compared using the Dinamap and Doppler techniques, and significant correlation was found. Ankle and brachial systolic, diastolic and mean pressures and ankle/brachial pressure indices for all three pressures were measured in a group of 12 normal subjects supine at rest, and after treadmill exercise, and a range of normal values defined. The main limitation of the Dinamap is its failure to measure pressures below 50mmHg. The Dinamap technique is a noninvasive, simple, reproducible and quick method of measuring ankle and brachial pressures in vascular surgical practice.

The early results of 34 exteriorisation resections of the colon are presented, 25 being emergency procedures and 9 elective. The operative mortality in the emergency group was 20% and there were no deaths in the elective group. All patients who survived the postoperative period have had their colostomies closed. The operation was technically simple and quick to perform. It is one of the safest methods of resecting colon. The technique proved to be a useful alternative to standard techniques in colonic perforation, colonic obstruction with proximal faecal retention, nonviable sigmoid volvulus, diverticular disease requiring resection, and colovesical and colouterine fistula.

In a retrospective survey of 63 cases of inverted nipple, unaccompanied by a palpable mass, 3 histologically confirmed carcinomas were found on combined clinical and mammographic examination - an incidence of 5%. No carcinoma was found in those patients under 50 years of age. The problem of the false negative mammogram is discussed.
