Mammography and breast pain.

Two hundred and three consecutive patients underwent mammography at both public and private facilities. Their patients were asked to complete a questionnaire which recorded their assessments of pain. There was a very low incidence of significant pain (4%). The rate was highest (10.9%) in those with pre-existing breast pain. This compared with a rate of 1.4% in those without pre-existing breast pain. A larger number of premenopausal women suffered from breast pain (69%). Breast pain was particularly common in the week prior to onset of menstruation. Therefore, routine mammography should be scheduled in a pain-free interval and, if possible, the week prior to onset of menstruation should be avoided.

A comparison of different doses of non-ionic contrast media in i.v. urography.

This study attempts to find out what is the appropriate dose of non-ionic contrast media to provide an acceptable study at the lowest possible cost. 139 adults with normal renal function were studied. Four different dose regimes were employed and a standardised set of I.V.U. films were obtained. These were reviewed by two independent assessors who were unaware of the dose regime used. Each I.V.U. was scored on a modified Fry regime. This survey showed a clear relationship between quality and dosage.

Assessment of D dimer assays for the diagnosis of deep vein thrombosis.

Sixty-two patients with suspected deep vein thrombosis were subjected to venography and to plasma D dimer assay by both rapid latex agglutination and enzyme immunoassay methods. The latex agglutination method was insensitive to the presence of deep vein thrombosis. In contrast, the enzyme immunoassay method was sensitive although of low specificity and for technical reasons not suitable for performance as an emergency test.

Narcotics and spasm of the sphincter of Oddi. A retrospective study of operative cholangiograms.

The operative cholangiograms of 112 patients undergoing elective cholecystectomy were reviewed independently and retrospectively by two radiologists who were not aware of the anaesthetic technique used. Fifty four patients who received opioid drugs either pre- and/or intra-operatively comprised one study group whilst 58 patients who received no opioids comprised the other. Spasm of the sphincter of Oddi was observed in two patients in the opioid group and in one patient in the non-opioid group. The use of opioid drugs as part of the anaesthetic management for cholecystectomy did not appear to interfere with the radiological interpretation of operative cholangiography nor to increase the low incidence of spasm of the sphincter of Oddi.
