In 10 patients at the age of 17 to 59 years the diagnosis of a cavernomatous transformation of the portal vein primarily was made by sonography and was confirmed by computer tomography and ...angiography, respectively. These findings were seen by chance when an abdominal ultrasound was performed in order to clarify splenomegaly or esophageal varices. The characteristics of the disease are the positive proof of a convoluted agglomeration of racemose venous structures that have replaced the normal single portal vein and signs of portal hypertension. The sonographic figures are so typical that ultrasound is the decisive procedure in its diagnosis and that direct or indirect splenoportography is not necessary. The present results show that clinical manifestations of cavernomatous transformation of the portal vein are delayed sometimes in to adolescence and that invasive diagnostic methods are only necessary when shunt operation is planned.
To determine the value of MRI in typical and atypical aortic dissections.
MRI investigations on 16 patients with aortic dissections were analysed retrospectively; for 8 patients CT investigations ...carried out at almost the same time were available for comparison.
In all cases the diagnosis of aortic dissection was possible from MRI and CT. If a dissection membrane and a double lumen were present these were detected in all patients by both methods. In three patients with atypical dissections, only an asymmetrical abnormal wall thickening as sole sign for the presence of an aortic dissection was seen. A differentiation between true and false lumen was possible in 16 of 17 MRI investigations and in 5 of 8 CT investigations on the basis of differing blood flow velocities or, respectively, the detection of a thrombus in the false lumen. The relationship of the dissection membrane to the large aortic branches as well as the determination of the branch vessel origin with regard to true or false lumen could be evaluated better with MRI than with CT.
Thus MRI has a significant role in the diagnosis and follow-up of aortic dissections. The advantage in comparison to the alternative spiral CT technique is, in addition to the absence of radiation exposure, the better analysis of the extent of the dissection as a result of the multi-planar slice orientation (especially in the region of the aortic arch and the arch vessel origins) without the necessity to administer iodine-containing contrast media.

La septième réunion régulière des ministres des Affaires étrangères des États membres du Forum méditerranéen s’est tenue à Funchal les 30 et 31 mars 2000, avec la participation du ministre chargé de ...la Communauté nationale à l’étranger et de la Coopération régionale de l’Algérie, du ministre adjoint des Affaires étrangères de l’Égypte, du secrétaire pour la politique extérieure et pour l’Union Européenne de l’Espagne, du Ministre des Affaires Etrangères de la France, du secrétaire général pou...
Monsieur le Ministre,Monsieur le Président de l’Université,Mesdames et Messieurs les doyens et professeurs,Étudiants du Caire, d’Égypte et du monde arabe, Je voudrais d’abord remercier Monsieur le ...doyen Mofid SHEHAB pour ses paroles de bienvenue. Je sais la contribution qu’il apporte à l’amitié entre l’Egypte et la France, tant à la tête de cette prestigieuse Université du Caire et qu’à celle de la Commission des Affaires étrangères de la Choura. Chers étudiants, j’ai souhaité vous rencontrer...
La confrontation Est-Ouest ayant pris fin, une nouvelle définition des relations de l’Union européenne (UE) et de l’Allemagne avec ses voisins du Sud et de l’Est, depuis le Maghreb arabe et Israël ...jusqu’à l’Asie centrale, en passant par la Turquie, est devenue nécessaire. La plupart de ces Etats sont marqués par l’islam. Les relations interculturelles de l’Europe avec ces pays sont aussi étroitement liées aux conditions intraculturelles en Europe, dans la mesure surtout où celles-ci sont déte...
Thirty-seven volunteers were inoculated intranasally with living attenuated influenza A 2 viruses. Rising titres of circulating antineuraminidase (AN) were detected in 14 of 17 infected volunteers. ...AN was also found in nasal secretions. Statistical analysis showed that there was a correlation between the titres of haemagglutination-inhibituig antibody (HI) and AN in nasal washings, and between AN in blood and washings. Resistance to infection could be predicted from antibody titres in 29 of 37 volunteers and blood AN alone predicted the outcome of 25 volunteers.
Pyritinol-HCl was tested for its impact on the cognitive functions of children with learning disabilities. This study is a contribution to scientific discussion on the complicated methodologic ...problems in evaluating the clinical efficacy of psychopharmacologic agents. Sixty-seven pupils of slow learner classes between the ages of 11 and 16 years were treated for 6 months with 300 mg pyritinol-HCl/24 hr or placebo under strict double-blind conditions. Drug intake was stimulated and controlled by means of intense psychosocial interaction with the mothers of the subjects. The dependence variables used to test medication effects were 22 parameters of cognitive performance measured in psychologic tests for perceptual and intellectual functions which were administered immediately before and after the medication phase. First the gainscores before and after treatment with pyritinol or placebo within the 22 cognitive parameters were statistically compared. In addition, an analysis of covariance on the corrected results of the second test (treating the results of first testing as covariates) and a two group discriminant analysis for overall differences were performed. None of the 22 parameters showed statistically significant treatment effects with respect to average performance (t (pyritinol - placebo) = 1.96 to 1.31), neither could the two groups be separated by discriminant analysis (Hotelling's T2 = 35.4, df - 22 and 43, P = 0.465). With respect to a variability of gainscores, however, in four parameters there was a significantly higher variance in the pyritinol group (F = 1.85-2.33, P less than 0.05, less than 0.02, respectively). This fact may signify that pyritinol-HCl had different effects on different subjects. By means of prognostic stratification we therefore attempted to define objective criteria for a selection of subjects with probable positive treatment effects. None of the 15 tested criteria, such as body weight, age, perceptual handicaps, or reduced short term memory, IQ range, proved, however, to be critical for a prognosis of pyritinol effects within the present test population.
