Marfan syndrome. A contribution to forensic medicine cases

A 19-year-old school boy suffered from fluctuating uncharacteristic chest pain in the last 20 h before his death. He died unexpectedly within a few minutes of a hemopericardium, which resulted from an aneurysmal rupture of the ascending aorta. The patient's past history as well as the autopsy and ultrastructural findings led to the diagnosis of Marfan's syndrome with alterations of the cardiovascular skeletal system but no ophthalmological involvement ("oligosymptomatic" form of Marfan's syndrome). Appraisal of the cause of death is made more difficult by the fact that medical treatment was undertaken on the same day, whereby subtotal liver crushing was established that had resulted from attempts at resuscitation.     

2 fatalities due to hyperthermia in infancy. A contribution to forensic medicine case reports of death caused by heat

Two infants aged 4 1/2 and 8 months are reported to have been exposed to overheating by an electric blanket and a heating fan in bed for a period of up to approx. 19 hours. Dehydration complicated the effects of overheating. Due to the case history in combination with the autopsy and histological findings as well as the absence of toxicological findings the following diagnosis could be established: "Death from exhaustion as a consequence of long-lasting heat effect and dehydration." The necessity of thorough investigations in causes of death during infancy is shown by means of the two cases above. If possible, the rectal temperature should already be taken by the coroner. The public should get informed about the risks caused by the use of electric cushions, heating fans as well as floorboard heating.     

Evolutionary dynamics in the voting game

Voter participation is immense but theoretically doubtful because there exists cost of voting and the probability of casting the deciding ballot is low. Game theoretic models (Palfrey and Rosenthal, 1985) confirm this paradox of voting. Individual optimization in the voting game is problematic with respect to the rationality and information requirements of traditional game theory. Therefore in this paper a non-optimizing but learning individual is considered. By individual learning the adjustment processes and equilibria of voter turnout are determined. Voters are able to learn to participate and substantial voter turnout is possible.     

Competition of newspapers and the location of political parties

In this paper we suggest a model for an analysis of how newspapers and political parties determine their ideological orientation and how both decisions depend on each other. Quite naturally dissemination of information plays an important role. The model is set up as a two-stage game. Because elements of horizontal as well as vertical product differentiation are present in this model location patterns in ideology space exhibit in general neither maximal nor minimal differentiation, although we keep quite close to the Downs model, with information as the most important distinguishing feature. Furthermore, the model shows by way of example that economic theory can be a useful tool to investigate issues which are central to communication science.     

Accidental drowning due to tropane alkaloid abuse

The cause of drowning deaths in good swimmers may be difficult to solve. After homicide, suicide and other kinds of immersion deaths have been ruled out, not only alcohol and narcotics, but also other psychotropic substances such as thornapple and angel's trumpet should be taken into consideration--at least in adolescents and young adults. The article reports on an accidental death by drowning under the influence of tropane alkaloids after consumption of a decoction of the flowers of angel's trumpet.     

Differential diagnostic aspects of forensically relevant findings in the brain stem]

Because of the extreme dense accumulation of vital structures (compared with other regions of the central nervous system), in the brainstem even small lesions may cause serious clinical symptoms. Judging the forensic relevance of macroscopically visible lesions requires the knowledge of the respective possible diagnosis. As shown in three case reports (67 years, teleangiectasis; 35 years, cavernoma; 49 years, secondary hemorrhage following trauma) this demands apart from the knowledge of the normal and pathological anatomy of the brainstem always the use of histological methods.     

Was treibt die Stimmbürger an die Urne? Eine empirische Untersuchung der Abstimmungsbeteiligung in der Schweiz, 1981‐1999

Zunächst werden die theoretischen Überlegungen kurz dargelegt, die zur Entscheidungs‐ bzw. zur Mobilisierungshypothese führen. Zudem wird die Theorie des ‘expressiven Wählens’ vorgestellt, und es wird auf zwei weitere Hypothesen über Bestimmungsgründe der Stimmbeteiligung eingegangen. Danach wird der Schätzansatz beschrieben, bevor wir uns mit den empirischen Ergebnissen beschäftigen. Sie sprechen nicht nur sehr stark für die Mobilisierungs‐ und gegen die Entscheidungshypothese, sondern zumindest bei den fakultativen Referenden spielen auch die erwarteten (bzw. befürchteten) finanziellen Auswirkungen eine entscheidende Rolle. Allerdings sind sie nur bedingt mit der Theorie des expressiven Wählens vereinbar.
