[Estimation of organ dose during radiological and computer tomographic examinations with calculations of the somatically significant doses (author's transl)].

The risks from radiation exposure during radiological diagnosis has usually been estimated in relation to genetic changes. Relevant information has been expressed as the genetically significant dose. In this paper we attempt to produce an analogous measure for evaluating the somatic risk in the form of a somatically significant dose index for radiological and CT examinations. It is shown that, for both types of examination, the two risk factors may be entirely different.

[Complications of angiography (author's transl)].

Report on complications on review of 2163 angiographic examinations-with comparison to these reported in the literature-with the resulting finding that there is no difference. The problems occuring in comparing individual data in this regard are pointed out.

[Diagnosis of the Paget-von Schroetter syndrome and monitoring of the therapeutic results (author's transl)].

Streptokinase or Urokinase can lead to complete healing in Paget-von Schroetter Syndrome. This tyne of lysis therapy should be instituted immediately or after the fourteenth postthrombotic day. The diagnosis should be verified by armphlebography. The therapeutic results must be controlled by phlebography in order to point out the need for continued therapy in case of thrombotic residual.

[Examinations of the pulmonary function of untrained and physically trained old men (author's transl)].

In tests there were determined the vital capacity and absolute and relative seconds capacity of 180 physical-trained sportsmen aged 55 to 89 and of 175 untrained, but clinically healthy test persons. The results of the different age-intervals are compared statistically. It was noticed, that vital capacity and absolute seconds-capacity of both groups decrease statistically significant with the age. Vital capacity and seconds capacity are in all age-intervals on a higher level with the trained sportsmen than the control group. The relative seconds-capacity showed no significant difference between the two groups. There is a clear statistic connexion between the vital capacity and the time obtained in a 5 000 meters run. One can suppose that in contrast to juvenile sportsmen a good pulmonary function is a contributory determinant of the performance of old sportsmen.

[X-rays in the eye of the general public. A survey of 181 interviews with office personnel (author's transl)].

For a pilot study, a random sample of 181 office personnel in steel companies were interviewed about their knowledge and feelings on X-rays and other forms of ionizing radiation. The general knowledge about the beneficial and detrimental aspects of X-rays was good, with education at school and news media reports being the main sources of information (70%). In general, the news media are considered to give objective and correct reports on this matter. 85% of the interviewed held ionizing radiation to be at least somewhat dangerous. Those with higher education (college/university) were significantly more vocal on the dangerous aspects. Concerning personal fear of X-rays, 30% were at least somewhat fearful. A significant correlation was found between statements on the dangerous aspects and subjective feelings of fear (anxiety). Interestingly, there was no correlation between general fearfulness (manifest anxiety) and fear of X-rays.

[Obstruction of the hepatic portion of the inferior vena cava: morphological characteristics and surgical treatment (author's transl)].

Operable obstructions of the hepatic portion of the inferior vena cava (IVC) are rare but probably diagnosed more frequently nowadays. Since 1969 we operated 2 patients, one of them twice. Concerning to these cases the problems of diagnosis, morphology and surgical treatment are discussed. In the patient, who were operated twice, we found the combination - which has not been reported in medical literature yet - of a membranous stenosis of the hepatic portion of the IVC and a large Eustachian valve obstructing the IVC.

[Neutron dosimetry in a 17-MeV betatron].

Measurements of neutron radiation around the 17 MeV betatron at the radiation clinic of the University Düsseldorf are reported. Two figures present isodose distributions of neutrons under different conditions of irradiation.

[A comparison of antibiotic resistance patterns and pyocine types between strains of Pseudomonas aeruginosa from animal and human sources (author's transl)].

291 strains of Pseudomonas aeruginosa from human bacteriological samples were compared with 102 strains which had been isolated from animals for frequency of pyocine-types and patterns of antibiotic resistance. 146 strains had been isolated from hospitalized patients and 145 from out-patients. More strains of animal origin were sensitive to carbenicillin and tetracyclines compared to strains of human origin. Since the frequency of different pyocine-types is the same in all three groups, it is concluded, that antibiotic resistance may be transferred from man to animal and vice versa via transfer of Pseudomonas aeruginosa.

[Lymph flow disorders following arterial surgery of the leg].

In a series of 342 arterial reconstructions of the iliacolic to popliteal arteries 24 patients with lymph vessel damage were observed. The diagnosis of lymphedema was established in 18 patients by clinical findings and in 2 of them the diagnosis was confirmed by lymphography with followup of 1 year. Three patients developed an internal lymphogenic cyst, 3 showed an external lymph fistula, and 1 patient developed an infection of a dacron bifurcation graft. The infection occurred when an additional occlusion of the left femoral artery was bypassed with an autologous saphenous vein graft and a lymph cyst in the groin, which was excised several times, became infected. The patient was treated successfully by excising the graft and performing an axillofemoral bypass. Although cases of surgical damage to lymph vessels following arterial reconstructions are rare in the literature, it is assumed that this complication occurs more often than reported, because of lack of lymphographic information.
