    Notes: Abstract - A case of a transdental fixation planned on the basis of ultrafast computed tomography is reported. This method allows to gain an insight in the osseous structures required for the operative procedure. Ultrafast computed tomography is superior to the convential radiographs in obtaining accurate information about the vertical bone supply and the extension of the facial osseous sinus wall. A set of axial CT-images with an extension of 3 mm was acquired in the region of the alveolar bone. By means of frontal reconstructions and data processing methods the thickness of the bone layer in transverse direction was accurately determined. The calculated bone thickness allowed to anchor a transdental self-tapping titanium screw.

    Description / Table of Contents: Background. Systemic sclerosis (SSc) is a generalized disorder of the interstitial tissues and vasculature with distinct abnormalities in three systems, immune and autoimmune, vascular and microvascular, and mesenchymal extracellular matrix (ECM), that lead to exuberant fibrosis. The aim of this study was to compare the number of blood vessel profiles in the marginal gingiva between SSc patients and patients with periodontitis but without SSc by using biopsies. Methods. Marginal gingiva and gingival papilla were obtained from 13 scleroderma patients and 8 patients with periodontitis after routine tooth extraction and gingival curettage. On the histological sections, immunohistochemical investigations were performed using the avidin-biotin complex method (ABC) and the monoclonal antibody CD 31/Clone JC70A (platelet endothelial cell adhesion molecule-1). Blood vessels were identified by light microscopy (original magnification × 400) and counted within 0.3615 mm2. Medians of blood vessel profiles were compared by Mann-Whitney U-test. Results. There is no statistical difference between the median of blood vessel profiles in the marginal gingiva of SSc patients as compared to the median of blood vessel profiles in the marginal gingiva of patients with periodontitis (P = 0.665). We did not discover avascular areas in the subepithelial connective tissue. Discussion. The pathological changes in the microvasculature in the dermis of SSc patients are not transferable to the marginal periodont, as intraindividual histological examinations of dermis and oral mucosa in relation to the degree of the disease are not available yet.
    Notes: Hintergrund. Die systemische Sklerodermie ist eine relativ seltene, generalisierte Erkrankung des Bindegewebes. Im Krankheitsprozess spielen entzündliche und vaskuläre Phänomene eine wichtige Rolle. Methode. Anhand von Bioptaten der marginalen Gingiva wurde nach indizierten Zahnextraktionen oder Kürettagen der Vaskularisationsgrad im subepithelialen Bindegewebe der Gingiva von Sklerodermiepatienten mit demjenigen von Patienten mit einer Parodontitis verglichen. Die Mikrogefäßdichte (MVD) wurde immunhistochemisch mit Hilfe des monoklonalen Antikörpers CD31/Clone JC70A (platelet endothelial cell adhesion molecule-1, PECAM-1) dargestellt und lichtmikroskopisch quantitativ erfasst. Die statistische Auswertung der Mediane der Kapillaranschnitte erfolgte mit dem Mann-Whitney-U-Test. Ergebnisse. Die Mediane der Kapillaranschnitte bei den Sklerodermiepatienten (n = 13) und den Patienten mit Parodontitis (n = 8) erwiesen sich statistisch als nicht signifikant verschieden (p = 0,665). Im subepithelialen Bindegewebe der marginalen Gingiva wurden keine avaskulären Zonen gesehen. Diskussion. Die in der Dermis von Sklerodermiepatienten ablaufende Angiopathie ist nicht ohne weiteres auf das marginale Parodont übertragbar, da intraindividuelle histologische Untersuchungen von Dermis und Mundschleimhaut in Abhängigkeit vom Erkrankungsstadium derzeit nicht vorliegen. Das vorliegende Ergebnis rechtfertigt nicht, Probeexzisionen der Mundschleimhaut zu entnehmen, um das Krankheitsstadium einer Sklerodermie anzuzeigen oder eine prognostische Wertung vorzunehmen.

    Description / Table of Contents: Zusammenfassung Niridazol, ein Nitrothiazol-Derivat, wies bei der Testung von 510 klinischen Isolaten vonGardnerella vaginalis hohe antimikrobielle Wirksamkeit gegen diesen Erreger auf. Die MHK-Werte waren im Bereich von 0,002 bis 1,0 mg/l; die MHK50 lag bei 0,02 mg/l, die MHK90 bei 0,067 mg/l.
    Notes: Summary Niridazole, a nitrothiazole derivative, demonstrated powerful antimicrobial activity against 510 clinical isolates ofGardnerella vaginalis tested. MIC's ranged from 0.002 to 1.0 mg/l with MIC50 and MIC90 values of 0.02 and 0.067 mg/l, respectively.

    Description / Table of Contents: Zusammenfassung Mittels Agardilutionstest wurde die Empfindlichkeit von 115 Campylobacter-Stämmen aus fünf Spezies gegenüber Metronidazol, seinen durch oxydative Metabolisierung entstandenen Hauptmetaboliten und Tinidazol bestimmt. Metronidazol und Tinidazol zeigten vergleichbare Aktivität. Der Hydroxy-Metabolit wies gegenüber den meisten Spezies, insbesondere aber gegenCampylobacter jejuni undCampylobacter pyloridis höhere Aktivität auf als die Muttersubstanz. Bei geringerer Aktivität gegenC. jejuni undCampylobacter coli wies das Säurederivat gegenüber den restlichen untersuchten Spezies ebenso hohe Aktivität auf wie Metronidazol. Gegenüber ausgewählten Nitroimidazol-Antibiotika bestanden Empfindlichkeitsunterschiede bei verschiedenen Campylobacter-Spezies.
    Notes: Summary The susceptibilities of 115 campylobacters, belonging to five species, to metronidazole, its principal oxidative metabolites and tinidazole were determined by an agar dilution method. The activities of metronidazole and tinidazole were comparable. The hydroxy metabolite was more active than the parent drug against most species, particularlyCampylobacter jejuni andCampylobacter pyloridis. Although the acid derivative was less active againstC. jejuni andCampylobacter coli, it demonstrated an equivalent degree of activity to metronidazole against the remaining species. Inter-species differences existed with respect to the susceptibility of campylobacters and selected nitroimidazole antimicrobials.
