    Notes: Abstract From Pseudomonas putida CFML 90-51 – a hospital isolate – a pyoverdine was obtained which is characterized by the unusual linkage by the ε-rather than the α-amino group of Lys in the peptide chain. The structure elucidation by spectroscopic methods and degradation reactions is reported.

    The structure of a pyoverdine from Pseudomonas sp. CFML 96.188 and its relation to other pyoverdines with a cyclic C-terminus (2000)

    Notes: Abstract From Pseudomonas sp. CFML 96.188 a pyoverdine was isolated and its primary structure was elucidated by spectroscopic methods and degradation reactions. This strain is of interest as it accepts the structurally different pyoverdines from several other Pseudomonas strains. They all have in common as a specific structural feature a C-terminal cyclic substructure, the importance of which for the recognition of a pyoverdine at the cell surface of a given strain will be discussed.

    D3 Lymph Node Dissection in Gastric Cancer: Evaluation of Postoperative Mortality and Complications (2000)

    Notes: Abstract Since November 1995 we have been performing a D3 lymph node dissection in patients undergoing an operation for gastric cancer with a curative intent. The aim of the present study was to evaluate whether this procedure results in an increased postoperative mortality or complication rate in a Western population. Between November 1995 and August 1997 the postoperative courses of 76 patients were retrospectively assessed (45.3 lymph nodes per patient, lymph node ratio: 0.16). The patient outcome was compared with data from a historic control group of patients (n = 383) in whom the newly established D2 dissection was studied in our department. Regarding the demographic, clinical, and tumor-pathologic data, and the choice of resection and reconstructive procedures, the two groups differed only slightly. The postoperative mortality of 1% was lower (vs 6.8%) while the overall complication rate of 34% (vs 32.1%) was identical. In particular, no anastomotic leakage (vs 9.4%) and fewer nonsurgical complications (17.1% vs 27.9%) occurred. The reoperation rate was 1% vs 9.7%. However, in 6% of the patients drainage tubes had to be inserted under computed tomographic guidance. The average hospital stay remained unchanged (21.9 vs 20.7 days). A D3 dissection was shown to be feasible while demonstrating no disadvantages in the patients when compared with the D2 procedure.

    Behandlungsstrategien bei der akuten komplizierten Divertikulitis (2000)

    Description / Table of Contents: Abstract Interval single stage resection with primary anastomosis is the new strategy in management of acute complicated colonic diverticulitis. With increasing tendency localized complications are treated with minimally invasive techniques. Life threatening peritonitis with evidence of free perforation in old, multimorbid, bad conditioned patients should be further an indication for 2-stage resection. Laparoscopic assisted Hartmann reversal can be done with minimally invasive risk in experienced hands.
    Notes: Zusammenfassung Die möglichst einzeitige, elektive Resektion ist der Trend in der chirurgischen Behandlung der akuten komplizierten Divertikulitis. Lokalisierte Komplikationen werden nach Abklingen der akuten Entzündung zunehmend minimalinvasiv reseziert. Auch bei der vital bedrohlichen Perforationsperitonitis ist eine Tendenz zur primär einzeitigen Resektion erkennbar. Im Stadium der fortgeschrittenen Peritonitis hat bei multimorbiden Patienten in schlechtem Allgemeinzustand die Diskontinuitätsresektion weiterhin ihre Berechtigung. Die Hartmann-Wiederanschlussoperation kann heute risikoarm und zunehmend laparoskopisch assistiert durchgeführt werden.

    Notes: Abstract Epistemic entrenchment, as presented by Gärdenfors and Makinson (1988) and Gärdenfors (1988), is a formalisation of the intuition that, when forced to choose between two beliefs, an agent will giveup the less entrenched one. While their formalisation satisfactorilycaptures the intuitive notion of the entrenchment of beliefs in a number ofaspects, the requirement that all wffs be comparable has drawn criticismfrom various quarters. We define a set of refined versions of theirentrenchment orderings that are not subject to the same criticism, andinvestigate the relationship between the refined entrenched orderings,the entrenchment orderings of Gärdenfors and Makinson, and AGM theorycontraction (Alchourrón et al., 1985). To conclude, we compare refinedentrenchment with two related approaches to epistemic entrenchment.

    Notes: Abstract Generalisations of theory change involving operations on arbitrary sets ofwffs instead of on belief sets (i.e., sets closed under a consequencerelation), have become known as base change. In one view, a base should bethought of as providing more structure to its generated belief set, whichmeans that it can be employed to determine the theory contraction operationassociated with a base contraction operation. In this paper we follow suchan approach as the first step in defining infobase change. We think of an infobase as a finite set of wffs consisting of independently obtainedbits of information. Taking AGM theory change (Alchourrón et al. 1985) as the general framework, we present a method that uses the structure of aninfobase B to obtain an AGM theory contraction operation for contractingthe belief set Cn(B). Both the infobase and the obtained theory contraction operation then play a role in constructing a unique infobasecontraction operation. Infobase revision is defined in terms of an analogueof the Levi Identity, and it is shown that the associated theory revisionoperation satisfies the AGM postulates for revision. Because every infobaseis associated with a unique infobase contraction and revision operation, the method also allows for iterated base change.
