BACKGROUND: Local antimicrobial systems have gained importance, as illustrated by current research on drug delivery systems (DDS). We aimed to develop materials that combine hemostatic and antimicrobial efficacy as well as adhesiveness for use in surgical tissue management. MATERIALS AND METHODS: Materials were evaluated by in vitro studies employing microbiological and technological methods. RESULTS: Antimicrobial impregnation of a collagen fleece, which is a pre-coated fibrinogen-based adhesive and therefore ready-to-use (TachoComb), is significantly more efficient--both in terms of the antimicrobial efficacy (p < 0.001) as well as the adhesive strength (p = 0.03) -than coating an antibiotic-containing collagen fleece "on-site" with fibrin glue. CONCLUSION: Due to ease of practical handling and favorable pharmacoeconomics, this DDS is recommended for both open and minimally invasive surgery.

A case of aortic valve disease associated with Tropheryma whippelii infection in the absence of other signs of Whipple's disease.

A case of endocarditis caused by Tropheryma whippelii is reported. The 69-year-old patient was diagnosed as suffering from severe aortic regurgitation requiring aortic valve replacement, but showed no other symptoms of Whipple's disease. T. whippelii was detected in the explanted aortic valve by broad-range PCR amplification of the 16S rDNA and subsequent sequence analysis of the product. The etiologic agent was classified as a type 2A sequence variant based on the 16S-23S intergenic spacer and the 23S rDNA (domain III) sequences. The histological examination of the aortic valve was compatible with Whipple's disease. A duodenal biopsy revealed an infection with Giardia lamblia, but T. whippelii and histological signs of Whipple's disease were not detectable.

Detection of cutaneous Leishmania infection in paraffin-embedded skin biopsies using the polymerase chain reaction.

In this study the polymerase chain reaction (PCR) with previously developed oligonucleotide primers was used to detect Leishmania aethiopica in paraffin-embedded skin biopsy specimens. The Leishmania-specific 120 base pair fragment of the kinetoplast deoxyribonucleic acid (kDNA) minicircles has been amplified from all parasitologically or histologically confirmed cases of cutaneous leishmaniasis (CL), as demonstrated by gel electrophoresis and hybridization with L. aethiopica kDNA. Control specimens from patients with skin diseases other than CL were all negative. Using PCR, Leishmania were demonstrated in the skin lesions of 7 cases in a group of 40 patients in whom the parasites could not be demonstrated by histopathology or culture in vitro although lesions were clinically suggestive of CL. These data indicate that PCR, carried out on DNA extracted from formalin-fixed and paraffin-embedded tissue specimens, is a valuable method for the diagnosis of CL, especially in chronic cases where the parasite load in the lesion is low.

[Erysipel at the lower leg combined with a peripheral peroneus nerve palsy--an unusual occurrence].

We present the clinical case of a fifty-year-old man who presented two times with a foot elevator paresis and an erysipel first on the right and after two months on the left side. Afterwards, we carried out a thorough case history with the help of clinical, radiological and magnetic resonance imaging. Even so the clinical pathology of the foot elevator paresis could not be manifested. A compartment syndrome could be discounted. In the context of the second stay during a neurology examination on both legs electromyography was performed and the nerve speed was tested. A peripheral peroneus paresis of unknown level and of unknown aetiology was demonstrated. The erysipel regressed rapidly under intravenous ampicillin antibiotics while the peroneus paresis was unchanged. The patent was released with a peroneus splint on both sides. With this case report we would like to point out the causes of peripheral peroneus paresis with regard to an additional erysipel. This case report is discussed regarding the possible aetiopathology and the current literature.
