    Description / Table of Contents: Summary Knowledge based systems can be helpful to give a wider group of users access to simulation. Classifications are given for systems according to their structure and their task-sharing approach. Among the latter are systems that enable automated model creation, support the interaction of user and expert system and others, that utilize simulation as a means of knowledge acquisition. Two examples are given: Simulation Craft and a system that will support rescheduling in production environments by combining expert systems, simulation and manufacturing systems.
    Notes: Zusammenfassung Wissensbasierte Systeme können helfen, die Simulation für eine breitere Anwenderschicht nutzbar zu machen. Dazu werden Klassifikationen nach der Architektur und nach der Aufgabenteilung vorgestellt. Letztere unterscheidet Programme zur automatischen Generierung von Modellen, Systeme, die den Benutzer bei der Interaktion unterstützen, und Expertensysteme, die Simulation zur Wissensakquisition nutzen. Als Beispiele werden Simulation Craft und ein System vorgestellt, das durch Koppelung von Expertensystemen, Simulation und einem PPS-System die Umdisposition in der Fertigungsplanung unterstützen soll.

    Notes: Abstract Knowledge-based systems (KBS) can help to make simulation available to a large group of users. We want to exemplify this by describing a decision support system (DSS) for short term rescheduling in manufacturing called SIMULEX. It couples expert systems, simulation, and a multiattribute decision making (MADM) procedure to assist the production manager. After an introduction to simulation as a problem solving tool, the current problems in production control and the goals of the project are described. Then, the various components of SIMULEX are explained in some detail. Some results and a short outlook conclude the article.

    Notes: Abstract The gastrocolic v. or Henle’s gastrocolic trunk was described in 1868 [9]. We suggest defining this vein as the confluence of the right gastroepiploic and right upper colic vv. We report two original cases of avulsion of the gastrocolic v. occurring during a blunt abdominal trauma. The aim of this paper is a description, based on the literature, of the anatomy of the gastrocolic v. in order to precise the lesional mechanism. The gastrocolic v. is present in 70% of individuals. It is short (less than 25 mm) but of major calibre (3 to 10 mm). The gastrocolic v. is situated close beneath the root of the transverse mesocolon, and travels along the anterior surface of the head of the pancreas. Anatomic variations are detailed and a meta-analysis of interpretable studies was made. Both the supra- and infra-mesocolic surgical approaches are described. The radiologic and surgical importance of the gastrocolic v. is discussed. The lesional mechanism in both our cases of injury of the gastrocolic v. is explained.

    Notes: Abstract The spinal dorsal horn is known for its important functional role in the field of transmission and modulation of sensory afferents. Because of this, the dorsal horn represents a target for numerous analgesic and antispastic procedures. Thus, it would be interesting to develop imaging dedicated to this spinal structure. The purpose of this study was to investigate the radiologic anatomy of the cervical dorsal horn by magnetic resonance imaging (MRI) (1.5T). The first step consisted in the validation of the anatomic information provided by MRI on 5 human cadavers. A spin-echo sequence (T2, 2000/45) enabled the demonstration of good correlations between histologic sections and axial MRI slices performed at the corresponding cervical levels. The second step was the 〈〈in vivo〈〈 exploration of 20 subjects, aiming at the development of a gradient echo sequence (T2*) with a conventional MRI unit, compatible with a routine clinical examination. The dorsal horn was clearly identified in 77% of the axial slices performed (n = 300). The angle between the dorsal horn axis and the sagittal plane was measured as from 25.5˚ at C2 to 40˚ at C8 segments. The results of this anatomico-radiologic study of the cervical dorsal horn suggest that preoperative MRI could be useful to design the surgical approach to this structure, as performed during cervical microsurgical drezotomy (DREZ = dorsal root entry zone) for the treatment of selected cases of chronic pain or disabling spasticity in the upper limbs.

    Notes: Abstract In a preceding study, we had reviewed and evaluated the anatomy sites available on the Internet. The evolution of the available sites, the disappearance of certain sites and the appearance of new sites led us to update this list. In addition, the German-speaking sites were included in the study, which previously included only the Anglophone and French-speaking sites. Forty-eight sites were indexed and their addresses are available on the site of the Laboratory of Anatomy of the Faculty of Medicine Lyon-Nord (http://rockefeller.univ-lyon1.fr/Anatomie-Lyon-Nord). Compared to the scores allotted in 1998, we noted in 1999 a significant increase (p = 0.03) in the total score (12.13 ± 2.98 vs. 11,23 ± 2,28/20), which shows that the quality of the anatomic sites available on the Internet has improved.

    Notes: Abstract Bilateral renal cortical necrosis as a rare form of acute renal failure was encountered in two patients with sepsis and acute renal failure. In both cases contrast-enhanced computed tomography showed characteristic findings: absent spacification of the renal cortex and enhancement of subcapsular and juxtamedullary areas and of the medulla without excretion of contrast medium. Establishing an early diagnosis and visualizing the extent of renal cortical necrosis by means of contrast-enhanced computed tomography allow a prognostic evaluation of renal function and further planning of therapy.
