Influence of an ionic and a nonionic (sodium meglumine diatrizoate and iopromide) x-ray contrast medium of hemorrheology.
In two groups of ten patients each, an ionic and a nonionic contrast medium was injected intravenously, for digital subtraction angiography of the supra-aortic branches, to examine the influence of hemorrheologic properties. Afterward, blood samples were obtained through a central venous catheter and evaluated by a new instrument (oscillating capillary rheometer and densitometer). The viscous and elastic components of the complex blood viscosity and the hematocrit decreased after injection of ionic and nonionic contrast media. A statistically significant difference between the patient groups could not be found. The evaluated results describe an improvement of the hemorrheologic properties after contrast media injection.

[Sudden infant death. An analysis of psychosocial conditions].
The Sudden Infant Death Syndrome (SIDS) has been studied mainly in a medical-biological view. In this paper emphasis is put on the fact that SIDS is also a psychosocial phenomenon: As the infant exists in a continuous exchange with his environment, his death can be considered a reaction to extreme stress load including psychosocial factors. In proceeding from that concept, the social and psychological conditions of 94 mothers of SIDS cases have been analyzed and compared with 68 mothers of healthy infants of similar age, urban/rural relation, and social class distribution. Both groups differed considerably. The SIDS group was more "jeopardized" in any aspect. Probability to die seems to increase with the number of accumulated risk factors. The conclusions drawn can be utilized for prevention.

Liver tissue characterization using computerized echography.
A digital echographic data acquisition and evaluation system was used in a clinical study including more than 100 patients with various local or diffuse liver tissue alterations. For diagnosis two decision methods are applied: first linear discriminant analysis and second a Bayesian method. Each A-scan is represented by a set of various numerical parameters from which only the most signal-distinctive ones are used for evaluation. The diagnostic results which will be presented and discussed have proved the method to be very sensitive and specific.

[Inlays as support for removable cast partial dentures].
On the basis of follow-up examinations in patients with removable cast partial prostheses, the author emphasizes the necessity of placing inlays as interlocks on abutment teeth, and he gives advice on inlay designs which are in conformity with prosthetic therapy.
