Assessment for three different forms of short-term dynamic psychotherapy. Findings from the Bergen Project.

Forty-four patients were assessed for three different short-term dynamic therapies, with an evaluation form based on Sifneos' criteria for Short-Term Anxiety-Provoking Psychotherapy (STAPP). Ten patients were ascribed to STAPP, 22 patients to Malan's Brief Psychotherapy (BP), and 12 patients to a more eclectic/integrative form of brief psychotherapy in this project called the FIAT model. 78% of the patients completed their treatment in agreement with the original ascription to therapy, with good results for all three therapies. The evaluation form seems to be a reliable and valid instrument offering a good and systematic basis for designing a tailor-made treatment format for different types of patients.

Brief dynamic psychotherapy for patients presenting physical symptoms.

Ten outpatients who complained of physical symptoms, without organic pathology, were treated with brief dynamic psychotherapy. Outcome ratings were provided by independent assessors at the end of therapy and 2 years post treatment. Improvement criteria included symptoms, adaptive functioning, and specific internal predispositions. The results showed that most of the patients gained substantially from their therapy experiences. Change did not only occur with regard to psychological difficulties, but also in their particular physical symptoms. Therapy gains at termination were maintained, and had even increased, at follow-up. Clinical improvement was confirmed by psychological test findings. In several patients marked positive change was also observed in their general body response patterns.

Comprehensive assessment of change in patients treated with short-term dynamic psychotherapy: an overview. A 2-year follow-up study of 34 cases.

Change was assessed in 34 patients at the end of short-term dynamic psychotherapy (STDP), and at 2 follow-ups (1 year and 2 years subsequent to treatment). The assessment was made from different perspectives and according to multiple criteria and methods of measurement. The results indicate that, when a particular form of STDP is selected according to each patient's ego resources, motivation for therapy, and motivation for change, approximately 90% of the patients will attain substantial symptom relief. The majority of the patients in this study also gave evidence of positive change in adaptive functioning, while one-third attained some dynamic/structural change as well. Clinically rated improvement was confirmed by changes in the patients' self-reported distress level (SCL-90), and from psychological test findings (MMPI). Improvement observed at the end of therapy was sustained throughout the 2-year follow-up period.

Description of flow phenomena in magnetic resonance imaging.

The magnetic resonance (MR) signal from the hydrogen nuclei of blood is not only determined by the MR parameters T1, T2 and proton density, but is strongly dependent on the movement of the protons. Magnetic resonance imaging (MRI) offers therefore the possibility to visualize the distribution of moving spins, especially blood flow, noninvasively and without contrast agents; moreover, the velocity of the moving spins can be quantified. Flow phenomena in MRI are a pretentious field because the complicated hydrodynamics of the living system is coded in the MR signal; therefore, an understanding of the underlying physical principle of the MR signal is required to interpret and extract flow information from the image. However, rather simple theoretical and experimental models of fluid transport in vessels allow to explain the main features of various effects observed in images.

Hepatic venography and wedge hepatic vein pressure measurements in diffuse liver disease.

Ninety patients with chronic diffuse liver disease were evaluated with free hepatic venography, wedge hepatic venography, hepatic vein pressure measurements, and liver biopsy. Free hepatic venograms were normal and minimally pruned in patients with hepatic sarcoidosis and fatty liver due to alcohol, and their biopsies showed little or no fibrosis. Pruning of hepatic vein branches on free hepatic venography correlated well with the corrected wedged hepatic vein pressure and with the degree of fibrosis in patients with alcoholic hepatitis, alcoholic cirrhosis, and postnecrotic cirrhosis. Free hepatic venography correlated better with hemodynamic measurements and fibrosis than did wedge hepatic venography. Free hepatic venography is a reliable predictor of the presence and degree of hepatic fibrosis and may be a useful alternative to liver biopsy in patients with clotting disorders.

Giant idiopathic thymomegaly.

Apart from the anterior mediastinal position and the usual size of the normal thymus, aberrant locations and extreme size variations may occur. This is illustrated by an eight month old boy whose histologically normal thymus presented as a large mass in the right hemithorax. It is the largest normal thymus on record in an infant. Thus, idiopathic thymomegaly should also be considered in the differential diagnosis of peripheral intrathoracic mass lesions.

The entity of non occlusive mesenteric ischemia: strophanthin effect on mesenteric blood flow in experimental animals.

Digitalis glycosides have the well known positive inotropic effect on the heart. Their effect on extracardiac vascular smooth muscle receives increasing attention. In experimental animals a significant decrease in mesenteric blood flow and an increase in mesenteric vascular resistance could be shown. Angiography of main mesenteric arteries, smaller arteries, and arterioles reveal typical vasoconstriction. Angiomorphometric measurements show good correlation between the decrease in vascular diameter and the increase in vascular resistance.

[Effect of strophanthin on intestinal blood flow. A contribution to the physiopathology of hemorrhagic enteropathy].

The purpose of the present study was to compare in canine experiments hemodynamic and angiographic effects on mesenteric circulation. I. v. administration of strophanthin is leading to an increase of arterial pressure and a decrease of mesenteric blood flow. Most consistent angiographic changes are attenuation and local vasoconstriction of peripheral vessels. The relationship between digitalis administration and mesenteric underperfusion leading to non-occlusive mesenteric ischemia is discussed.

[Permanent stop of renal circulation by embolisation with microspheres. Preliminary report (author's transl)].

The risk of tumor cell dislodgement during operative removal of carcinoma of the kidney is reduced by preoperative occlusion of the renal arteries. After the intraarterial injection of 250 mu microspheres a complete blockage of the intrarenal circulation was found in all three experimental animals for at least 2 hrs. In the other two dogs the blockage remained unchanged over 24 hrs. Subsequent experiments shall demonstrate that the simple embolisation technique using microspheres is more stable than other methods.

[Influence of the treatment of subclinical mastitis on the electric conductivity of milk before ejection].

10 cows (German Brown x Brown Swiss) with 29 infected quarters (14 Staphylococcus aureus, 10 esculin positive streptococci, 5 Staphylococcus spec.) were treated daily after morning milking over a period of 4 days. Ampicillin and cloxacillin (500 mg each per dose) were administered to all 40 quarters intracisternally. During the evening milkings on 4 test days (day 3 before treatment, day 1 of treatment, days 5 and 9 after the last treatment), electrical conductivity based on 25 degrees C (EC) was measured in fore milk. To avoid ejection of alveolar milk, EC measurement was the first contact to the udder. Independent of the initial level, EC of all quarters was elevated by 2.1 mS/cm on average at the first milking following the first treatment. 9 days after the end of treatment, EC had declined to the initial level in all quarters classified as mastitic, non specific and latent infected before treatment. By contrast, EC values of healthy quarters remained elevated compared to their initial level (p < 0.01). This might be due to increased cistern tissue permeability caused by mechanical and pharmacological effects of antibiotic treatment. Despite the fact that somatic cell count and total bacteria count were reduced by treatment (p < 0.01), results showed that EC measurement on the first days following treatment was unsuitable for checking the success of treatment.
