[Computerized tomography in the evaluation (author's transl)].

CT can clearly demonstrate dilation of intra- and extra-hepatic bile ducts due to mechanical obstruction. Note is made that the intrahepatic bile must not necessarily participate in dilation in obstructive jaundice. The cause in 27 cases observed in our institutions was as follows: 16 pancreatic tumors; 1 stone; 2 extrahepatic bile duct obstructions; 4 liver lesions (tumor and cirrhosis) and 4 with cause unknown. Furthermore, CT is helpful in the evaluation of hepatogenic non-obstructive jaundice such as due to primary liver cell carcinoma (hepatoma), metastases to the liver and advanced cirrhosis of the liver. The value of CT in the evaluation of different types of cholestasis is demonstrated by several exemplary cases; and the problems of differential diagnosis are pointed out.

[Radiographic findings of periosteal reactions in systemic bone disorders (author's transl)].

Periosteal reaction is frequently the first sign of systemic disease affecting the skeleton, including generalized osteopathia. It can be generalized, focal, monostotic or polyostotic and shows solid, lamellary or interrrupted spiculae-like reaction. A reliable diagnosis is possible from the interpretation of these changes, as for instance with spiculae: Very dense and evenly arranged spiculae are only seen in hemolytic anemias and metastases of neurogenic tumors. Onionskin like periosteal reaction with simultaneous transformation of the diaphyseal cortex are difficult to interpret. However, in case of hyperparathyreoidism, subperiosteal resorption and transformation of the diaphyseal cortex permit precise diagnosis. Follow-up examinations have prognostic and therapeutic value. The knowledge of the different morphology of periosteal reaction associated with systemic disease (including generalized osteopathias) is important in diagnostic radiology.

Does long term haemofiltration provoke secondary hyperparathyroidism?

One thousand nine hundred and forty-nine haemofiltration procedures have been performed since 1976; 4 different types of haemofilters have been tested in gravimetric and volumetric haemofiltration machines. Balance studies revealed a diminished calcium intake of about 1/3 of that found in conventional dialysis. Magnesium balance is negative and leads to decreasing serum Mg values. Inorganic phosphate is removed in similar quantity to dialysis. PTH levels increase during 3--18 months of treatment, whereas 25-OH-D3 levels rapidly fell, gc-globulin- and HCT-levels did not change markedly. g-c globulin could be detected in filtrate samples in remarkable amounts, 25-OH-D3 was found in traces. Radiologically no apparent alteration occurred. We recommend Vitamin D supplementation to compensate for the losses and thereby avoid development of secondary hyperparathyroidism.
