    Description / Table of Contents: Zusammenfassung Eine 41jährige Frau verstarb eines Morgens innerhalb weniger Stunden infolge massiver rektaler Blutungen. Bei der Obduktion wurden eine komplette Leberzirrhose, Zeichen der portalen Hypertension, flüssiges Blut im gesamten Dickdarm und eine hochgradige Anämie festgestellt. Blutungsquelle war eine makroskopisch kaum sichtbare, rupturierte submuköse Varize im Colon sigmoideum als Folge des Pfortaderhochdrucks. In der Nachbarschaft und der weiteren Umgebung der Rupturstelle fanden sich reichlich erweiterte Venen mit Wandsklerose und Intimaverdikkung sowie paravasale Eisenpigmentablagerungen als Hinweis auf bereits früher abgelaufene Blutungen. Zum Nachweis der Blutungsquelle waren eine sorgfältige Inspektion und Präparation des Darmes sowie zahlreiche Stufenschnitte mit H.-E., Elastica-van Gieson und Eisenfärbung nötig.
    Notes: Summary A 41-year-old woman died within a few hours one morning due to massive rectal hemorrhage. At autopsy, complete liver cirrhosis, signs of portal hypertension, liquid blood in the entire colon, and high-grade anemia were detected. The source of bleeding was a ruptured submucosal varix in the sigmoid colon, which was almost invisible even microscopically and had been caused by portal hypertension. In the vicinity, and somewhat further away from the rupture site, numerous, greatly dilated veins with wall sclerosis and intimal thickening, as well as paravascular iron deposits, were found as indications that severe hemorrhages had already occurred earlier. To detect the source of bleeding, meticulous inspection and dissection with hematoxylin and eosin, elastica van Gieson, and iron staining, were necessary.

    Tod im tetanischen Anfall (1984)

    Description / Table of Contents: Zusammenfassung Es wird über einen Fall von latenter Tetanie bei einer 24jährigen Frau berichtet, die seit ca. 12 Jahren mehrfach tetanische Anfälle — meist ausgelöst durch äußere Reize — hatte. Eines Abends wurde die Frau tot in der Diele der Wohnung neben dem Telefon in tetanischer Krampfhaltung der oberen Extremitäten gefunden. Auslösende Ursache für den tetanischen Anfall war ein Telefonat. Die drei Nebenschilddrüsen waren unauffällig. Lichtmikroskopisch konnte linksventrikulär eine tagealte, eitrige Myokarditis nachgewiesen werden. Die beiden pathogenetischen Möglichkeiten der zum Tode führenden Kausalkette werden diskutiert. Ohne Kenntnis der Vorgeschichte hätte sicher die Myokarditis das Hauptgewicht für die Erklärung des Todes gehabt. Erstaunlich ist die Tatsache, daß ein klinisches Symptom, nämlich die tetanische Krampfhaltung, in der Totenstarre fixiert wird.
    Notes: Summary A case of latent tetany in a 24-year-old woman is reported. She had suffered several attacks of tetany in the last 12 years, mostly triggered by external stimuli. One evening, the woman was found dead in the hall of her flat beside the telephone with the upper limbs in a tetanic convulsive attitude. The attack of tetany was triggered by a telephone conversation. The parathyroid glands were normal. Day-old purulent myocarditis could be demonstrated in the left ventricle under the light microscope. The two possible pathogenetic explanations of the causal chain leading to death are discussed. It was astonishing that a clinical symptom (tetanic convulsion) was fixed in rigor mortis.

    Contrecoup fractures of the anterior cranial fossae as a consequence of blunt force caused by a fall (1990)
    Springer
    Acta neurochirurgica 105 (1990), S. 24-29

    ISSN: 0942-0940
    Keywords: Contrecoup fractures ; craniocerebral trauma ; fall

    Topics: Medicine
    Notes: Summary Contrecoup fractures of the base of the skull are regarded as rare in the clinical literature. In our material (n=171 falls on the same level and on or from stairs), the overall frequency of contrecoup fractures of the anterior cranial fossa in fatal cranio-cerebral trauma due to falls was 12%, as compared to 24% with occipital point of impact of the head. The relationships between the impact site on the head, form of fracture at the point of impact with involvement of the skull cap and/or the base of the skull, coup and contrecoup injuries of the brain, localization of contrecoup fractures in the anterior cranial fossa and the occurrence of monocle and spectacle haematomas display a major variability. Fractures occur in the form of simple fractures and as impression fractures (fracture fragments or fracture boundaries displaced to the inside). Clinical diagnosis is difficult because of the concealed position of the anterior skull base. Contrecoup fractures become of forensic medical significance when symptoms of a frontobasal injury occur for the first time after trauma which has occured some time in the past and when the question arises as to the causal connection with the original trauma. In investigation of living persons, it may be difficult to decide whether haemorrhages in the region of the orbit and its vicinity result from a direct blunt force or derive from fractures of the base of the skull, especially contrecoup fractures.

Das Ereignis wird zum Anlaß genommen, über die Zuordnung derartiger Verletzungsbilder und die Beweggründe von Gewaltäußerungen unter Geschwistern zu berichten.
    Notes: Summary A $$2{\raise0.5ex\hbox{$\scriptstyle 1$}\kern-0.1em/\kern-0.15em\lower0.25ex\hbox{$\scriptstyle 2$}}$$ -year-old boy inflicted on his 7-day-old brother suction and bite injuries of the head with loss of tissue of nose and lips. Place of the incident was the parents' bed. The event motivated us to report on the assignment of such injuries and the reasons for sibling violence.

    Instructional strategies and tactics for the design of introductory computer programming courses in high school (1987)

    Notes: Abstract This article offers an examination of instructional strategies and tactics for the design of introductory computer programming courses in high school. We distinguish the Expert, Spiral and Reading approach as groups of instructional strategies that mainly differ in their general design plan to control students' processing load. In order, they emphasize topdown program design, incremental learning, and program modification and amplification. In contrast, tactics are specific design plans that prescribe methods to reach desired learning outcomes under given circumstances. Based on ACT* (Anderson, 1983) and relevant research, we distinguish between declarative and procedural instruction and present six tactics which can be used both to design courses and to evaluate strategies. Three tactics for declarative instruction involve concrete computer models, programming plans and design diagrams; three tactics for procedural instruction involve worked-out examples, practice of basic cognitive skills and task variation. In our evaluation of groups of instructional strategies, the Reading approach has been found to be superior to the Expert and Spiral approaches. The authors wish to express their gratitude to Sanne Dijkstra, Otto Jelsma and Georg Rakers for their helpful comments on a draft of this article. Correspondence concerning this article should be addressed to Jeroen J. G. van Merrienboer.
