    Description / Table of Contents: Zusammenfassung Bei 433 Patienten mit Probeexcision im Bereich des Halses fanden sich neben Lymphadenitiden in erster Linie hämatologische Malignome und Metastasen maligner Tumoren. In 4,8 % traten behandlungsbedürftige Komplikationen auf, zum einen Wundheilungsstörungen (Hämatome, Entzündungen), zum zweiten neurologische Komplikationen des Nervus accessorius. Bei 4 Patienten bildeten sich diese vollständig zurück, einmal blieb eine Parese des Musculus deltoideus bestehen. Die Analyse des Krankengutes läßt erkennen, daß vor allem ungeeignete Narkoseverfahren (Lokalanaesthesie) bei in der Tiefe gelegenen, schlecht abgrenzbaren Tumoren zu Komplikationen geführt hatten.
    Notes: Summary In 433 cervical biopsies lymphadenitis, metastases of malignant tumors and of the haematologic system could be found first of all. In 4.8 % complications needed a further treatment, firstly trouble in wound healing (haematoma, inflammation), secondly neurological complications of the accessorial nerve. These complications receded in 4 patients completely, in one patient a paralysis of the deltoid muscle continued. The analysis of our patients suggested that unsuitable anaesthesia (local anaesthesia) for deeper-seated, badly demarked tumors is responsible for most of the complications.

    Notes: Summary Perturbations of hematopoietic regulation ranging from transient granulocytopenia to rare cases of bone marrow failure are associated with infections due to hepatitis A virus (HAV). In an attempt to elucidate the pathogenetic mechanisms we had previously established that HAV has a direct suppressive effect on human bone marrow progenitors (CFU-GM, -GEMM, BFU-E). These studies were extended to long-term bone marrow cultures (LTBMC): Inoculation of bone marrow mononuclear cells with HAV did not interfere with the establishment of an adherent stromal layer, nor did the inoculation of already established layers cause any morphologically recognizable changes to the stroma. In contrast, a significant and progressive decline of the CFU-GM content in the culture supernatants was demonstrated. HAV antigen was detected by APAAP stain in a subpopulation of stromal cells, and sequential estimations of virus titers in the supernatants provided evidence for viral replication in primary bone marrow cultures. Interferon-gamma and tumor necrosis factor-alpha levels of infected cultures did not differ from those of uninfected controls. These findings argue for a direct suppression of (pre-) CFU-GM by HAV in a model system (LTBMC) lacking an immune defense which would limit viral replication.
