    Notes: Summary Three adult dialysis patients developed ascites after having received repeatedly the plasma substitue hydroxyethyl starch (HES 40/0.5). In two cases (total dose 180, and 330 g HES, respectively) the ascites was reversible after discontinuation of the HES administration. In the third case (total dose 915 g HES) the ascites could be controlled only by implantation of a Denver shunt. In this latter case it was shown by histological, electron microscopical, and biochemical findings that the ascites was caused by hepatic sinusoidal obstruction due to an extreme storage of HES in the sinusoidal lining cells. Additional storage was detected in hepatocytes, bile duct epithelia, endothelial cells, and fibroblasts in the portal tracts. Biochemically HES was found in liver tissue at a concentration of 4% (w/w). Although in renal impairment plasma clearance of HES is not significantly different from normal individuals, long-term administration of HES must be regarded inadvisable because of tissue storage which apparently is especially significant in this condition.

    Description / Table of Contents: Summary Report of two cases of Wegeners' granulomatosis, who were treated with high dosis of corticosteroids. One patient died of a massive hemorrhage after rupture of an aneurysm of a kidney artery fourteen days after begin of treatment. The histological examination showed a scary-healed arteritis. Such changes were observed in other organs too. The glomerulitis was rather stationary. The second case lived for almost one year after begin of treatment. Depending on the corticosteroid dosis clinical remissions and improvement of the arteritis were seen on serial muscle biopsies. The post mortem findings were as well scary healing of the arteries, glomeruli and of the perivascular mesenchyma as necrosis of the glomeruli and of the lung tissue. The latter are considered to be the morphologic correlate to the terminal events during which the corticosteroids had no influence on the course of disease. The pathological findings are discussed with regard to the defined criteria of the disease known from the literature. These are likely altered by intensive therapy.
    Notes: Zusammenfassung Es wird über zwei Fälle Wegenerscher Granulomatose berichtet und die Frage des Effektes einer Corticosteroidbehandlung erörtert. Klinisch waren im einen Fall die Remissionen in Abhängigkeit von der Dosis überzeugend; in dem anderen Fall konnte eine Besserung nicht erzielt werden, da die Ruptur eines Nierenarterienaneurysmas als Komplikation einer abgeheilten Arteriitis letal endete. Pathologisch-anatomisch standen Vernarbungsstadien der Erkrankung im Vordergrund. Ihre Dignität hinsichtlich der Beurteilung des Corticosteroideffektes wird diskutiert. Mit Abwandlungen des sonst üblichen morphologischen Bildes durch die Therapie muß gerechnet werden.

    Notes: Aims : Eosinophilic heart syndromes are rare in Western countries and include endocarditis parietalis fibroplastica (EPF) and hypersensitivity myocarditis (HM). There are striking differences in natural history and morphological findings. Since diagnosis can be difficult when analysing small myocardial biopsies lacking the characteristic histological features, we studied a set of immunohistochemical markers in order to characterize the activation status of the infiltrating eosinophils to distinguish between these two entities.Methods and results : This study is based on the investigation of seven explanted hearts and one left ventricular specimen collected during implantation of a left ventricular assist device from a total of seven patients with HM. Also investigated were three right and three left ventricular specimens from five patients with EPF. We used antibodies (Ab) against EG1, and EG2, CD44, and CD69 which have been described as markers to distinguish between resting and activated eosinophils. The EG1 to EG2 ratio of eosinophils and the immunoreactivity against CD44 showed no differences between the two entities. However, eosinophils in the EPF were completely negative for CD69, whereas eosinophils reacted positively within the HM group.Conclusion : The immunohistochemical investigation of eosinophilic heart diseases using antibodies against CD69 can be a useful tool to distinguish between hypersensitivity myocarditis and endocarditis parietalis fibroplastica.

    Description / Table of Contents: Summary We report on a male, 31 year old, Turkish patient with an intracardiac mass in the right ventricle, reduction of performance and weight, as well as intermittent fever. No eosinophilia was documented in the peripheral blood; cardiac function was primarily normal. Besides the differential diagnosis of Löffler's endocarditis (endomyocardial fibrosis) an inflammatory disease and a malignant cardiac tumor were suggested. The diagnosis of Löffler's endocarditis could not be confirmed morphologically by echocardiography nor histologically by right ventricular biopsy. Operative removal of the mass lesion was neccessary because of fast tumor progression, fulminant pulmonary embolism, and infiltration of the tricuspid valve. Only then, histologically Löffler's eosinophilic endocarditis of thrombotic stage was diagnosed. Antiphlogistic therapy with cortisone was initially performed. With a dose reduction after 6 months, a relapse of the thrombotic mass occured. Therefore, continuous treatment with cortisone and azathioprine was induced followed by further tumor regression and further clinical stabilization since 8 months of treatment.
    Notes: Zusammenfassung Wir berichten über einen 31jährigen türkischen Patienten mit einer rechtskardialen Raumforderung, Leistungsminderung, Gewichtsabnahme und intermittierenden Fieberschüben. Im peripheren Blut bestand keine Eosinophilie, die kardiale Funktion war primär unauffällig. Neben einer Endokarditis fibroplastica Löffler bestand differentialdiagnostisch der Verdacht auf ein entzündliches Geschehen sowie einen malignen Herztumor. Bei echokardiographisch untypischer Morphologie der rechtsventrikulären Raumforderung konnte durch Myokardbiopsie die Diagnose nicht gesichert werden. Bei raschem Wachstum der Raumforderung, fulminanter Embolie und Infiltration in die Trikuspidalklappe konnte erst durch die operative Tumorexstirpation die histologisch-pathologische Diagnose einer Endokarditis fibroplastica Löffler im thrombotischen Stadium gestellt werden. Die Behandlung bestand in einer antiphlogistischen Therapie mit Kortikosteroiden. Im Auslaßversuch kam es nach 6 Monaten zu einem Tumorrezidiv. Eine Steroid-Dauermedikation in Kombination mit Azathioprin führte anschließend zu einer erneuten Tumorregression und Stabilisierung seit 8 Monaten nach Beginn der Medikation.

    Notes: Summary A 21-year-old man was hospitalized with repeated bleeding from the gastrointestinal tract, the cause of which could not be detected by gastroscopy, colonoscopy or arteriography. After the third surgical intervention he died of uncontrollable bleeding. At autopsy, marked and partly ulcerated duodenal varices were found to be the cause of the bleeding. They were part of a collateral circulation that had developed from chronic obstruction of the inferior vena cava, where thrombosis had arisen in association with neonatal renal vein thrombosis. There was consecutive renal infarction which had required a left nephrectomy on the 2nd day after birth.

    Notes: Abstract We report a case in which an adult form of Niemann-Pick disease (type B of NPD) was associated with a rapidly progressive generalized AL amyloidosis of kappa type. Both diagnosis were made by biopsy, the NPD by bone marrow biopsy and fibroblast culture, the amyloidosis by liver biopsy. Malignant non-Hodgkin lymphoma was not found. The patient, a 67-year-old woman, died from hepatic coma subsequent to a progressive liver failure. We discuss possible relations between the lysosomal storage disease and the development and rapid progression of amyloidosis.

    Notes: Abstract After irradiation or chemotherapy of tumors of the head and neck, histological alterations might be difficult to assess. In 30 cases of squamous cell carcinomas of the pharynx, changes in argyrophilic nucleolar organizer region (AgNOR) counts were investigated after therapy. After treatment a significant decrease of AgNOR counts was detected (P 〈 0.001). No significant differences could be found between groups treated with radiotherapy, chemotherapy or a combination of radiotherapy and chemotherapy. These findings suggest that AgNOR counts might be useful to assess cytotoxic effects on a subcellular level.
