    Description / Table of Contents: Zusammenfassung Fibroblasten wurden aus Hautbiopsien von Patienten mit unterschiedlich aktiven Formen der progressiven systemischen Sklerodermie gewonnen und in vitro kultiviert. Nach 24stündiger Markierungszeit mit 3H-Prolin wurde die Gesamtsynthese des Kollagens gemessen sowie nach Veränderungen im Kollagentypenverhältnis gesucht. Während das Verhältnis von Typ-I-zu Typ-III-Kollagen in alle Stadien der Patienten dem gesunder Kontrollen vergleichbar war, zeigte sich in dem aktiven Stadium im allgemeinen eine deutlich erhöhte Kollagensynthese. Fibroblastenkulturen, die durch eine normale Kollagensynthese charakterisiert waren, ließen sich weder durch Zugabe von Kontroll-noch von Sklerodermie-Patientenserum zu einer höheren Kollagensynthese stimulieren.
    Notes: Summary Fibroblasts were cultured from skin biopsies of patients with systemic sclerosis in different stages of the disease. In vitro synthesis of collagen was checked after a pulse with tritiated proline. The ratio between type I and type III collagen was normal in all patients. Six of seven cultures derived from patients in the active state showed an increased synthesis of collagen relative to other proteins. Addition of serum (normal and diseased) to the culture medium did not stimulate synthesis of collagen in any culture with normal collagen synthesis.

    Notes: Autoantibodies have become an important diagnostic tool for the diagnosis of connective tissue diseases (CTD) and for defining certain subgroups of these diseases. According to the reationship between clinical symptoms and the specificity of autoantibodies they can be classified into two major groups: (1) marker antibodies which are highly specific for a particular disease entity and (2) symptom specific autoantibodies associated with certain clinical expressions or subgroups. Titers of autoantibodies can vary from low to high but do usually not correlate with the status of disease activity. In order to interpret the significance of autoantibodies in CTD and to predict the course of disease it is necessary not only to identify single autoantibody specificities but to consider the combination in which they appear.

    Notes: Four patients are described, two with histologically proven multiple foci of bowenoid lesions, one patient with bowenoid lesions and Bowen's disease, and one patient with two keratoacanthomas, most of the lesions occurring in non sun-exposed but photochemically treated areas of the body. These patients had received long-term PUVA treatment for their psoriasis. Two patients had a history of arsenic intake. The possible relationship of these epidermal lesions to light treatment is discussed.

    Notes: In order to elucidate the pathogenesis of the skin lesions in ‘benign gonococcal sepsis’ direct immunofluorescence of an early macular lesion and routine histopathology of a mature papulopustular lesion in a patient with septic gonococcal dermatitis have been performed. Histopathology of the mature skin lesion revealed a pattern of allergic vasculitis. Direct immunofluorescence showed exclusively deposits of C3 around and within the capillaries and in the basement membrane zone. No specific IgG, IgM, IgA or C4 deposits could be demonstrated. This, together with serological findings and reports from the literature, suggests an important pathogenetic function for complement, activated through the alternative pathway by means of gonococcal endotoxic lipopolysaccharide, in the pathogenesis of the skin lesions in benign gonococcal sepsis.

    Notes: Histochemical and electron microscopic studies were carried out on the newborn mouse model of the staphylococcal scalded skin syndrome to investigate the mechanism of action of the staphylococcal epidermolytic toxin that causes it. Histochemical studies showed that an intra-epidermal split develops below the subcorneal zone which is rich in catabolic enzymes (the so-called esterase-acid phosphatase-rich band). However, histochemical alterations in the enzyme pattern could not be demonstrated. The earliest change revealed by electron microscopy was a widening of the intercellular space, with the formation of microvilli at the level between the stratum spinosum and stratum granulosum where the split later occurs. A clearing of the peripheral cytoplasm along the cell membranes was also revealed. In pre-split areas, adhesion between cell membranes of adjacent cells seems to be lost; desmosomes continue to hold the cells together but the split develops when these are broken by mechanical pressure. Later, damaged cell membranes may be seen. Extracellular keratinosomes remain unchanged.Although these findings do not agree with the already divergent results of other studies, they help support the findings of all groups that cases of the Lyell syndrome produced by staphylococci do not occur through necrolysis; it is therefore inappropriate to continue applying the term ‘toxic epidermal necrolysis’ to such cases.
