[Criteria for diagnostic and therapeutic methods of vascular embolization (kidneys, spleen, liver) (author's transl)].

Basing on the findings in patients with extensive carcinomas of the kidneys, the article reports on the various possibilities of application of occlusion spirals (Gianturco's method), of injectable occlusion materials and a combinations of both methods. In the authors' own experience, the spiral technique has mostly proved successful in achieving embolization of the arteries of the kidney 24 hours before surgery. Both the spiral technique as well as the use of injectable emblizates and a combination of both are used in the treatment of macrohaematurias in non-operable kidney tumours. The article reports on the technical conditions, indication and methodical limitations of embolization of the splenic artery, basing on three actual cases. The conditions and technique of embolization of branches of the hepatic artery are discussed by means of the findings obtained in two patients with liver metastases of an insulinoma.

An investigation of the intellectual capabilities of juvenile offenders.

One hundred two cases were drawn randomly from the Bronx Family Court Mental Health Clinic's active files. Clients were given a Wechsler Intelligence Scale for Children--Revised, Bender Gestalt, and Wide-Range Achievement Test Reading. Results indicated that approximately one third were functioning the mentally defective range, one third in the borderline mentally retarded range, and one third in the low average to average range. Almost half showed perceptual deficits correlated with minimal brain dysfunction. Results were highly significant, suggesting that delinquents apprehended and seen in our clinic are likely to be of borderline intelligence or below, showing evidence of minimal brain dysfunction. Hypotheses are discussed, as is the need for appropriate treatment facilities.

[Value of phlebography in the diagnosis of edema of the leg].

In the diagnosis of leg edema, important phlebographic procedures are explained in terms of their technique and the information they provide. Ascending phlebography is the most important procedure for diagnosis of phlebothromboses, post-thrombotic syndromes, occlusions of the deep veins of other genesis, perforans insufficiency as well as vessel malformations. Additional administrations of selective contrast medium, intraoperative techniques as well as transosseous contrast medium administration are mentioned as rare supplementary methods. Peripheral open measurement of venous pressure constitutes an important additional documentation of vein function. The limits of the information provided are explained with reference to the normal phlebogram as well as to findings of venous reflux disturbances in the region of the deep veins, especially in acute thrombosis and occlusion of deep veins.

[Subclavian steal syndrome; results of operative treatment (author's transl)].

36 patients-average age 56 years--suffering from subclavian steal syndrome underwent surgery. No postoperative mortality. In a percentage of 84 the results obtained were satisfactory. In the 4 years period after the operation 7 patients died, 28 patients could now be followed up. Only in 2 cases the bypass became occluded in the intermediate time.

The effect of induced erythrocythemia upon 5-mile treadmill run time.

The purpose of this experiment was to investigate the effect the infusion of 920 ml equivalent of autologous blood would have upon 5-mile time (5MT) and both local (RPE-L) and cardiovascular-respiratory (RPE-B) ratings of perceived exertion. Twelve long-distance runners undertook a series of four competitive 5MT trials on a treadmill. Four test conditions were utilized: pre-saline trial; post-saline trial after 920 ml saline solution; pre-blood trial; and post-blood trial after 920 ml equivalent of whole blood. All subjects took all trials in this double-blind placebo crossover experimental design. Running time and RPE were recorded at each 0.5 mile split. Blood samples were taken before and after each trial. The data were analyzed via a repeated-measures ANOVA. In general, the following results were noted following the blood infusion when compared with the other three trials: a significantly higher hemoglobin (Hb) concentration; a significantly lower RPE-L and RPE-B during the first two miles of the run; and a significantly faster 5MT. Within the limitations of this experiment, it was concluded that the infusion of 920 ml equivalent autologous blood would increase performance capacity in an athletic event characterized by high levels of aerobic energy expenditure.

[Peptic ulceration of the oesophagus. Report of 18 cases].

From 1968 to 1979 881 patients suffering from peptic ulcerations were seen at the Surgical Dept. of the "Medizinische Akademie - Dresden". In a percentage of 2.04 these ulcers were located in the oesophagus (n = 18) near the cardia. Due to the high rate of complications following conservative treatment the authors recommend resection of the oesophageal ulcers and oesophago-gastrostomy. After operation no gastro-oesophageal reflux could be observed.

[Immunoglobulins after experimental liver transplantation in pig].

During a period of 14 days after porcine liver transplantation immunoglobulins IgA, IgG, and IgM were investigated. IgA and IgG were slightly elevated at the end of investigation. The increase in IgM was higher and significant. This rise in immunoglobulin-level is thought to be a result of immunisation by parenchymatous insults after liver transplantation.

[Behavior of serum proteins after experimental liver transplantation in swine].

A typical tendency of the course of the serum proteins is to be observed after experimental liver transplantation. The animals survived the transplantation only a short time if the serum proteins lay below 50 p. c. of the starting value after the transplantation. In animals that survive a longer time 3 groups with characteristic kinds of development are formed. The albumins and the Gc-globulins seem to normalize themselves. Hemopexin and lipo proteins decrease continuously after the transplantation. The "acute-phase-reactants" increase permanently and exceed considerably the pre-operative value.

[X-ray diagnosis of Crohn's disease in the intestine (author's transl)].

The article describes the essential roentgenologic findings associated with Crohn's disease in the intestine, manifested as stenoses, thickening of the walls, fistula formation and pseudodiverticula or appearance of Bodart's intermediary segment, on the basis of characteristic findings, followed by valuation in respect of the exclusive possibility of diagnosis via radiology. The article goes into details in respect of differential diagnosis criteria, particularly within the frame of tumour diagnosis. Differentiation can be effected with the help of findings in peritoneal carcinosis and intestinal changes induced by radiation.

[Vein-bypass or endarterectomy in femoropopliteal reconstruction (author's transl)].

The authors report on 124 femoropopliteal arterial reconstructions in 112 patients. 6 years after surgery 23.6 percent of bypasses and 67.0 per cent of endarterectomised arteries were obstructed but 65.5 percent of patients with bypass procedures and 64.2 percent of the patients with endarterectomy were free from complaints.
