    Notes: Zusammenfassung Wir stellen einen 49jährigen Patienten vor, der nach einer Auslandsreise an einer Q-Fieberinfektion mit atypischem Verlauf erkrankte. Beim Q-Fieber handelt es sich um eine Infektion durch Coxiella burneti, einer Rickettsienart. Während die Erkrankung üblicherweise unter dem Bild eines fieberhaften Infektes (oft verbunden mit einer interstitiellen Pneumonie) verläuft, kann gelegentlich doch die Leberbeteiligung ganz im Vordergrund stehen. Auch unser Patient litt an einem unklaren, hochfieberhaften Infekt mit erhöhten Leberenzymwerten. Histologisch fand sich eine granulomatöse Hepatitis mit multiplen Fibrin-Ring Granulomen. Außerdem waren einzelne Granulome auch im Knochenmark nachweisbar. Obwohl Fibrin-Ring Granulome in der Leber nicht pathognomonisch für das Q-Fieber sind, so stellt diese Infektion doch bei weitem die häufigste Ursache für diese Granulomform dar. Daher kann der Nachweis von Fibrin-Ring Granulomen vor allem bei atypischen, apneumonischen Verläufen des Q-Fiebers diagnostisch den entscheidenden Hinweis liefern.

    Notes: Abstract Short tandem repeat loci are ideal markers for forensic and paternity case work. A high degree of polymorphism, as determined by gross length measurement, is very often due to complex underlying sequence variation. In the present study, we have studied the sequence structure and population genetics of two short tandem repeat polymorphisms at loci D8S639 and D11S488 in German Caucasians from the region of Hesse. Sequence data revealed a considerable polymorphism at both loci. Locus D8S639 is characterized by a tetranucleotide (AGAT)n repeat pattern with (GAT) and (AGGT) repeats dispersed throughout several alleles. These microvariations lead to alleles differing by one base pair or alleles of identical size. At locus D8S639 we observed 17 allelic lengths comprising 25 different alleles. Alleles at locus D11S488 possess a compound repeat region consisting of (AAAG)n and (GAAG)n repeats. At locus D11S488 we observed 15 allelic lengths with a total of 24 alleles. Allelic lengths increased in size by 4bp increments corresponding to the addition of one tetranucleotide repeat unit. Population data of loci D8S639 and D11S488 revealed a high polymorphism with heterozygosity rates of 0.85 (D8S639) and 0.91 (D11S488).
