RESUMEN
Computertomography of the kidney is, in combination with the conventional non-invasive methods, a highly exact diagnostic process. It is very important especially in cases of tumours, bleeding, retention of urine in the kidneys and unilaterally quiescent kidneys. The use of boluscomputertomography and series--computertomography not only increases the exactness of diagnosis but should also yield information on functional dynamics.

A 70 years old patient is presented who was nephrectomized because of carcinoma of the kidney following retrograde pyelography with Thorotrast in 1940. Despite of local application of the contrast medium thorotrastosis was also seen in liver, spleen and probably in bone marrow. Possible causal connections are discussed. Thorium was identified in the kidney and in the liver with an electron beam microprobe.

A newborn infant was transferred to our hospital because of gastro-intestinal hemorrhage, starting a few hours after birth. Because of fetal distress a cesarean section had been necessary. The clinical examination as well as the results of the laboratory tests revealed nothing abnormal. In an upper gastro-intestinal X-ray series there was evidence for a duodenal ulcer. Under conservative treatment the baby recovered and has remained in a good condition without any bleeding episode until now. A repeat upper gastro-intestinal X-ray series was done at the age of 5 months and no evidence of ulceration could be found. The incidence and the reason of such an ulcer in the new born period is shortly discussed.
