Follow-up after radical surgery for colorectal cancer. Design of a randomized study.

The value of different follow-up examinations after radical surgery for colorectal cancer has not been proven. The risk of such programmes, including invasive examinations, may invalidate the possible benefit from early diagnosis of recurrent and metachronous cancer. The present trial is a randomized study, evaluating possible benefit from a very detailed programme compared to that of virtually no follow-up. The design is presented, but so far no more than 207 of the 600 patients wanted for trial, have been included. Differences in mortality rates, survival and morbidity will be evaluated and the influence of repeated polypectomy upon risk of metachronous colorectal cancer will also be estimated.

Intensifying screens in soft tissue radiography.

Certain screen-film combinations were tested in the low voltage range (26 to 40 kV, tungsten target) and compared with an optimal non-screen industrial film. The dose reduction was of no consequence as compared with the loss in image quality. Some physical properties of the screens giving rise to the failure are discussed.

Filtration in soft tissue radiography.

The influence of K-edge filters in combination with tungsten target tubes has been analysed in the low voltage range. It appears that these filters do not offer any advantages with this target material. Al-filtration, applicable to different types of soft tissue radiography of joints is discussed.

Soft tissue radiography in painful shoulder.

Specialized soft tissue radiography was applied to the shoulder region to differentiate between shoulder peritendinitis and radiating cervical pain. The technique is presented, together with the results of a clinical trial. Local inflammation was demonstrable even in the absence of calcific deposits.

Influence of secondary radiation on image quality.

On the basis of observations concerning non-screen films and xerox plates a theory is proposed as to how the image quality is impaired by secondary radiation. The theory includes an explanation of why xerox plates and industrial roentgen films of a high silver content are less affected by secondary radiation than conventional roentgen films.

Soft tissue xeroradiography of the shoulder joint.

Soft tissue xeroradiography of the shoulder joint has been compared with a film technique arrived at previously. The xerox plates gave a lower radiation dose to the patient without loss of information. The film technique requires a tungsten target tube with an extra thin glass window (=0.5 mm Al), while the xerox technique may be used with standard tubes.

Urothelial renal pelvic tumours in phenacetin abusers.

The appearances of renal pelvic tumours at urography and pyelography in 25 phenacetin abusers were correlated with the microscopy of operative specimens. Radiography was found to contribute to the preoperative assessment of malignancy grade.
