The characteristics of 4 contrast media for bronchography are compared, namely, iodized oil, iodized oil with sulphadiazine, a viscous solution of diodone with methyl cellulose, and a new suspension of a diodone derivative in an isotonic solution (dionosil). The defects of the iodized oil and of the water-soluble contrast medium are analysed. A series of 28 examinations in 25 cases, employing dionosil, is reported and it is concluded that the use of this contrast medium represents a real advance in bronchography.
*An extract from a paper read to the Cape Town Branch of the South African Association of Surgeons on 15 August 1952. The degree of activity of a carcinoma of the breast is the most important single factor controlling the prognosis. Apart from that, inadequate treatment is the main reason for the poor results of treatment. A new method of staging of carcinoma of the breast is recommended. It is based on the clinical assessment of the existing pathology. It is recommended that the treatment should depend on the stage of the carcinoma.
