    Notes: Abstract Uninary tract infections (UTI) are common, with frequencies ranging from about 1 to 10% in different age groups, Gram-negative bacteria dominate as causative agents. Defects in host resistance to bacteriuria have not been defined at the molecular level. The results of the present study demonstrate that endotoxin-induced inflammation mediates bacterial clearance from the kidneys. Genetic or pharmacologically induced defects in this function drastically impaired the natural resistance to infection.

    Notes: [Auszug] The Cape flora of South Africa grows in a continental area with many diverse and endemic species. We need to understand the evolutionary origins and ages of such ‘hotspots’ to conserve them effectively. In volcanic islands the timing of diversification can be precisely measured with ...

    Notes: The predominantly wind-pollinated order Poales includes about one third of all monocot (Angiosperm) species, with c. 20,000 species dominating modern savanna and steppe vegetation. Recent improvements in understanding relationships within the order allow phylogenetic optimizations of habitat preferences and adaptive character states, enabling exploration of the factors that have influenced evolution in this successful order. Poales probably originated in the late Cretaceous in wet nutrientĐ??poor sunny habitats. By the Paleogene the lineage had diversified into swamps, the forest understory, epiphytic habitats, and nutrient-poor heathlands. The Neogene saw major diversifications of the grasses and possibly the sedges into fire-adapted vegetation in seasonal climates and low atmospheric CO2. Diversification into these habitats was facilitated by morphological features such as the sympodial habit and physiological factors that allowed frequent evolution of CO2-concentrating mechanisms.

    Notes: Regulation of the mucosal inflammatory response to Gram-negative bacteria was analysed. The interleukin 6 (IL-6) secretion, influx of polymorphonuclear leucocytes into urine, and bacterial clearance from the kidneys were compared between Balb/c (nu/nu) and nu/± mice, with and without ciclosporin (CsA) treatment. There was no significant influence of the nu genotype on any of the host responses measured. CsA pretreatment significantly decreased II-6 secretion in both nu/nu and nu/± mice, but did not affect bacterial clearance or the leucocyte response in any mouse strain tested. Tissue damage, in addition to bacterial infection, resulted in significantly higher levels of IL-6 than bacterial infection alone. Tissue-damaged mice were significantly less likely to clear the bacterial infection than their non-damaged counterparts, but there was no significant difference in the leucocyte response. CsA pretreatment did not significantly reduce the levels of IL-6 in the tissue-damaged mice. These results demonstrate that the mucosal inflammatory response to Gram-negative infection, including IL-6 secretion, is nu-independent, and that bacterial infection alone or in combination with tissue damage induce IL-6 secretion by two different pathways.

    Description / Table of Contents: Zusammenfassung Die Differentialdiagnose des intra- und eatrahepatischen Verschlußsyndroms wird aus der Sicht des Internisten und Pathologen abgehandelt. Einleitend werden die Grundlagen der Gallesekretion und des Galletransportes er örtert, daran anschließend das diagnostische Vorgehen (klinische Hinweise, Laborbefunde, Laparoskopie, Leberbiopsie). Zur Vermeidung des Indikationsfehlers einer Operation ist die Kenntnis der Krankheitsbilder mit intrahepatischer Cholestase notwendig. Hierzu gehören Cholestasen durch Arzneimittel oder Schwangerschaft, das Alkohol-Lebersyndrom (einschließlich Zieve-Syndrom), die chronisch-destruktive nichteitrige Cholangitis (primäre biliäre Lebercirrhose) und das Dubin-JohnsonSyndrom. Extrahepatische Cholestasen müssen so schnell wie möglich einer chirurgischen Behandlung zugeführt werden, während die intrahepatischen Cholestasen eine konservativ-internistische Therapie erfordern. Die einzelnen diagnostischen Methoden besitzen eine unterschiedliche Wertigkeit. Nur die Synthese aller Methoden ermöglicht eine optimale Diagnose.
    Notes: Summary The differential diagnosis of the intra- and eztrahepatic occlusion syndrome is dealt with from the point of view of the internist and the pathologist. In the introduction the fundamental facts regarding secretion and flow of bile are presented. This is followed by a presentation of diagnostic procedures (clinical signs, laboratory findings, laparoscopy, liver biopsy). Knowledge of the clinical picture of intrahepatic cholestasis is necessary to avoid making mistakes in the indications for operation. These clinical pictures include cholestasis due to drugs or pregnancy, the alcohol liver syndrome (including Zieve's syndrome), chronic destructive non-purulent cholangitis (primary biliary cirrhosis of the liver), and the Dubin-Johnson syndrome. Estrahepatic cholestasis should be treated surgically as soon as possible; intrahepatic cholestasis requires conservative, medical treatment. The various diagnostic methods possess different values. Only by synthesis of all procedures will it be possible to achieve optimal diagnosis.

    Notes: Abstract Background: Unsuspected malignancy remains a problem for the laparoscopic surgeon. The aim of this study was to evaluate the risk of ovarian micrometastasis in patients with breast cancer who undergo laparoscopic oophorectomy. Methods: We analyzed 25 premenopausal women with breast cancer who underwent therapeutic laparoscopic oophorectomy. The patients were subdivided into the following two groups according to ovarian pathology: group A with and group B without breast carcinoma micrometastasis. We then reviewed the follow-up data for both groups, with special attention to metastasis of the abdominal wall. Results: Twelve of 44 ovaries removed by laparoscopy showed ovarian breast carcinoma micrometastasis. There were no predictive factors of micrometastasis. After a mean follow-up of 38.1 months (95% CI: 29.2–46.9 months), none of the patients with proven micrometastasis developed metastasis of the abdominal wall, and the 21 puncture sites were inconspicuous. Conclusions: Although 32% of patients may have unexpected ovarian micrometastasis, laparoscopic oophorectomy in patients with breast cancer remains a safe procedure.
