    Notes: Abstract. A 26-year-old man with acute deterioration of recurrent abdominal pain was admitted to the hospital. Plain film (abdominal radiographs), spiral computed tomography (CT), and barium contrast studies were performed. A left paraduodenal hernia causing acute jejunal obstruction was identified on upper gastrointestinal barium studies and spiral CT. Pre- and postsurgery examinations were compared, and relevant radiological findings were identified. Spiral CT provided excellent visualization of the pathognomonic displacement of the inferior mesenteric vein. RID=""ID=""〈e5〉Correspondence to:〈/e5〉 G. J. Schaffler

    Description / Table of Contents: Résumé L'objectif de cette étude a été d'évaluer les propriétés antioxydatives du cocktail multivitamine Omnibiota®, contenant les vitamines α-tocophérol, de l'acide ascorbique, du rétinol et du complexe vitamine B, pour diminuer les peroxydations lipidiques et améliorer l'oedème de jambe après reconstruction vasculaire chez l'homme. Cinquante et un sujets ont été sélectionnés, 27 formant le groupe témoin, et 24 patients recevant le cocktail en intraveineux avant la reconstruction vasculaire. Tous les patients avaient une maladie artérielle occlusive chronique, sauf deux qui souffraient d'un traumatisme artériel. Le MDA-TBARS dans le plasma, quantifié par HPLC, comme mesure de la peroxydation lipidique, était significativement augmenté (p〈0.001) dans le groupe contrôle une heure après le début de la reperfusion et a diminué jusqu'aux valeurs du départ dans les deux heures suivantes (0.73±0.26, 1.21±0.48, 0.99±0.48, 0.73±0.33 nmol/ml). Dans le groupe traité, le MDA-TBARS n'a pas dépassé les valeurs de base pendant la période de reperfusion (0.93±0.30, 0.70±0.29, 0.65±0.23, 0.70±0.37 nmol/ml). L'oedème des membres inférieurs, exprimé en circonférence de l'extrémité de la jambe, était signficativement plus augmenté (p〈0.008) dans le groupe contrôle (30.7±4.04 vs. 35.35±4.12 cm) que dans le groupe traité (29.25±5.13 vs 29.76±5.70 cm). Ces résultats suggèrent que le traitement vitaminique antioxydatif pourrait être utile dans la prévention de la peroxydation lipidique, réduisant ainsi l'oedème des extrémités.
    Abstract: Resumen El objeto del presente estudio fue evaluar las propiedades antioxidantes del coctel multivitamínico Omnibionta® que contiene las vitaminas α-tocoferol, ácido ascórbico, retinol y el complejo B, en cuanto a disminuir la peroxidación lipídica y reducir el edema en las operaciones de revascularización de extremidades en humanos. Se seleccionaron 51 individuos: el grupo control de 27 pacientes y el grupo de tratamiento de 24 pacientes que recibieron el coctel multivitamínico por vía intravenosa antes del comienzo de la reperfusión. Todos los pacientes exhibían enfermedad arterial oclusiva aguda o crónica, excepto 2 pacientes con trauma arterial. Se hicieron determinaciones de MDA-TBARS en el plasma, cuantificado por HPLC, como medida de la peroxidación lipídica, encontrándose que se hallaba significativamente aumentada (p〈0.001) en el grupo control 1 hora luego del comienzo de la reperfusión y que descendió hasta los niveles basales en el curso de las siguientes 2 horas (0.73±0.26, 1.21±0.48, 0.99±0.48, 0.73±0.33 nmol/ml). El edema de la pierna, según la circunferencia de las extremidades, apareció significativamente elevado (p〈0.008) en el grupo control (30.7±4.04 vs. 35.35±4.12 cm) en comparación con el ningún aumento en el grupo de tratamiento (29.25±5.13 vs. 29.76±5.70 cm). Tales resultados sugieren que el tratamiento vitamínico antioxidante puede ser de valor en la prevención de la peroxidación lipídica con disminución del edema de la extremidad.
    Notes: Abstract The objective of this study was to evaluate the antioxidative properties of the multivitamin cocktail Omnibionta® (α-tocopherol, ascorbic acid, retinol, vitamin B complex) in terms of diminishing lipid peroxidation with improvement of leg edema performance after limb revascularization operations in humans. Fifty-one subjects were selected; the control group contained 27 patients and the treatment group 24 patients, who received the vitamin cocktail intravenously before the start of reperfusion. All patients suffered from acute or chronic arterial occlusive disease, except two subjects with arterial trauma. MDA-TBARS in plasma, quantified by HPLC, taken as a measure of lipid peroxidation was significantly increased (p〈0.001) in the control group 1 hour after reperfusion onset and decreased to its baseline value within the following 2 hours (0.73±0.26, 1.21±0.48, 0.99±0.48, 0.73±0.33 nmol/ml). In contrast, in the treatment group MDA-TBARS did not exceed the baseline value during the reperfusion period (0.93±0.30, 0.70±0.29, 0.65±0.23, 0.70±0.37 nmol/ml). Leg edema, expressed by extremity circumference, was significantly (p〈0.008) elevated in the control group (30.7±4.04 cm versus 35.35±4.12 cm) compared to a lack of increase in the treatment group (29.25±5.13 cm versus 29.76±5.70 cm). These results suggest that antioxidative vitamin treatment might be valuable in preventing lipid peroxidation and decreasing extremity edema.

    Description / Table of Contents: Zusammenfassung Die zentrale Stellung des Protein C und S innerhalb des Blutgerinnungssystems ist durch eine Vielzahl von Patienten belegt, bei denen ein angeborener oder erworbener Mangel zu gesteigerten thrombembolischen Komplikationen geführt hat. Wahrend der angeborene, homozygote Protein-C- und -S-Mangel ohne Therapie kaum mit dem Leben vereinbar ist, manifestiert sich der heterozygote Defekt als abgeschwächte Form meist spontan zwischen dem 20. and 50. Lebensjahr. Erworbener Protein-C-Mangel ist ein starker Indikator für gestörte Leberfunktion und tritt unter bestimmten Bedingungen auf. Typisch für Protein-C- and -S-Mangelzustände sind venöse Thrombosen der oberflächlichen und tiefen Beinvenen, der Mesenterialvenen, der Zerebralvenen, der Nieren- und Axillarvenen Bowie Pfortaderthrombosen und Pulmonalembolien. Viele der Merkmalträger leben über längere Zeit völlig asymptomatisch und entwickeln im Anschluß an Traumen, Operationen, Schwangerschaft und Wochenbett ausgedehnte thrombembolische Komplikationen. Wir berichten über einen 60jährigen, männlichen Patienten, der nach totalem Hüftgelenkersatz zunächst links, darn rechts eine fulminante, rezidivierende Thrombose der Bein-Becken-Venen mit den klinischen Zeichen der Pulmonalembolie bot. Die Gerinnungsfaktorenanalyse ergab einen ausgeprägten, funktionellen (Typ II) Protein-C-Mangel (Protein-C-Reagenz koagulometrisch, Behring Institut). Eine 2. Patientin entwickelte eine deszendierende Beckenvenenthrombose gegen Ende der Schwangerschaft. Es erfolgte eine venöse Thrombektomie mit temporärer AV-Fistel, die sich post partum wiederum verschloß. Eine nochmalige venöse Thrombektomie mit neuerlichem Reverschluß nach der Entlassung komplizierte den Verlauf. Eine darauffolgende Lysetherapie konnte die Wiedereröffnung der Venenstrombahn nicht mehr erzielen. Wahrend sich ein normaler Protein-C-Gehalt nachweisen ließ, war der funktionelle (Typ II) Protein- S-Gehalt (IL-Instrumentation Laboratory Protein S-Test) erniedrigt.
    Notes: Summary Protein C and S are important factors in blood coagulation reported in many papers about people who suffered from thrombembolic diseases related to inherited or acquired deficiencies. Homozygous protein C/S deficiency is lethal in most cases without therapy. Heterozygous deficiency is moderate and complications occur between the 20.–50. year of age. Acquired protein C/S deficiency is a strong parameter for liver function. The typical clinical manifestations of protein C/S deficiencies are superficial and deep leg vein thrombosis, thrombosis of the mesenterial, cerebral, renal and axillary veins, portal vein thrombosis and pulmonary embolism. Most of the affected people live disease free over a longer period and develop thrombembolic complications during and after trauma, surgical interventions, pregnancy and puerperium. We report our experience with a 60 years old male who had developed a severe bilateral iliofemoral vein thrombosis with signs of pulmonary embolism after total hip replacement. An extented functional protein C deficiency (type II) was investigated by coagulation tests (Protein C Reagent, coagulometric from Behring Institute). A second female patient developed a descending iliofemoral vein thrombosis during pregnancy. Venous thrombectomy with arteriovenous fistula was performed, but reocclusion occurred after delivery. Redo-surgery was undertaken and a second reocclusion took place 10 days later. Further lysis therapy was not able to reopen the venous system. Whereas immunological and functional protein C levels showed normal ranges, the functional protein S level was markedly reduced (IL-Instrumentation Laboratory Protein S-Test).

    Notes: Abstract The diagnostic value of the decrease in percentage of immunoglobulin G1 (%IgG1) in breast cancer was analyzed with special emphasis on early tumor stages. IgG1 and total IgG were preoperatively measured in the sera of a total of 801 individuals using a modified quantitative affinity chromatography. Group A consisted of 174 healthy individuals of both sexes, group B of 324 female patients with benign breast disease, and group C of 303 patients with invasive and non-invasive breast cancer. Within group C, 13 patients presented with intraductal carcinoma, and 22 patients with a pT1a-tumour (diameter less than 0.5 cm). The %IgG1 values were compared among groups A, B and C. In addition, correlations were sought between %IgG1 values of group C and tumor size, stage (UICC), histopathological grade and oestrogen (ER) and progesteron receptor (PR) expression. The mean value of %IgG1 in group A was 63.3 ± 0.5 s.e.m., in group B 57.75 ± 0.4 s.e.m. and in group C 52.37 ± 0.5 s.e.m. The differences of mean values were highly significant between all three groups. Sensitivity and specificity of %IgG1 to discriminate between group A and C were 75% and 87%, and between group B and C 62% and 63%, respectively. The significant decrease of %IgG1 in total serum IgG is able to distinguish patients with breast cancer of more than 5 mm in diameter from healthy controls and patients with benign breast diseases. Finally, calculated posterior probabilities revealed that within certain concentration limits %IgG1 may provide predictive information with high xprobabilities.
