Detection of ketosis in vitreous at autopsy after embalming

Ketosis occurs in ketoacidosis or malnourishment. When either is suspected in relation to a death, it may be important to analyze for ketosis at autopsy. We encountered a case where starvation was suspected in a deceased nursing home resident, where the body had been embalmed prior to autopsy. Gas chromatography (GC) was unable to separate acetone from formaldehyde, a component of embalming fluid. The Acetest is a simple test that can detect acetone and acetoacetate in body fluids. We validated the Acetest with GC on vitreous. The Acetest and GC were consistent except at very low levels of acetone or acetoacetate. The sensitivity of the Acetest for acetoacetate in vitreous was 10 mg/dL, consistent with early starvation. Significant interference from embalming fluid did not occur. The Acetest was negative in the described case. The Acetest is a simple and useful test for the detection of ketosis in embalmed autopsies.     

Parties and Voters: What Creates the Ties?

The increasing instability in the electorate and the party system forces us to reconsider the Lipset-Rokkan thesis about the frozen party system. In this approach, cleavages played a major role, but in Western Europe, this role has diminished significantly. The frequent shifts in voter allegiance call for a new understanding of the mechanisms that connect voters and parties. A reinterpretation of the concepts of a "frozen party system" or "cleavages" is not enough. We need a new theory about the strategic interaction between parties and a floating electorate.     

Determinanten politischer Kultur am Beispiel des Schwyzer Stimmverhaltens

The new institutionalist approach is heavily committed to the idea that institutions matter. This article explores this commitment by examining the institutions of corporatism using comparative data in order to relate these to those of Konkordanzdemokratie. A neo-institutionalist perspective may be employed to illustrate how the institutions of Konkordanzdemokratie and macrocorporatism are related, both in terms of their origins as well as their policy outputs and outcomes. This article shows that both the conditions and the configuration of outputs and outcomes of Konkordanzdemokratie and corporatism are different. Therefore, one should clearly distinguish between these two sets of institutions. In a cross-sectional approach the configuration of socio-economic outcomes connected with these institutions are not as impressive as often claimed.     

Radiologically determined DMF index variations for forensic age estimation of young adults

The eruption and mineralization of third molars are the main criteria for dental age estimation of living people involved in criminal proceedings. Since the development of third molars is usually completed by the age of 19 or 20 years, this feature cannot be used to ascertain whether a person has attained the forensically relevant age of 21 years. This study examined whether the DMFT index or the third molar DFT index could supply reliable information enabling conclusions to be drawn about whether a person has reached the age of 21. To this end, 650 conventional orthopantomograms of German subjects aged 18 to 30 years were evaluated. The DMF index variations considered were found to be unsuitable for determining whether a person is over 21 because they displayed a weak correlation with age and considerable individual scatter. A high indicative value can only be attributed to a third molar DFT index of 4, although this is rarely observed in the relevant age group. An X-ray examination of the medial clavicular epiphyseal cartilage is, therefore, strongly recommended when assessing whether a person has attained 21 years of age.     

Suicide risk in outpatients with specific mood and anxiety disorders

The present study examined the relationships between specific anxiety, mood disorders, levels of hopelessness, and suicide ideation. The sample consisted of 606 outpatients recruited from several psychiatric settings. It was found that dysthymia was significantly associated with hopelessness. Patients presenting major depressive episode with higher anxiety symptoms had significantly increased scores on the hopelessness scale. Major depressive episode and bipolar disorder, but not dysthymia, were significantly associated with higher levels of suicide ideation. Increased levels of anxiety symptoms in patients with dysthymia were associated with increased levels of suicide ideation, while increased depressive symptoms in patients with specific phobia and generalized anxiety disorder were associated with significantly lower levels of suicide ideation. The findings suggest that depressive disorders, but not anxiety disorders, constitute risk for suicide. Moreover, the differentiation between a depressive and an anxiety disorder as the principal diagnosis, as well as the assessment of anxiety-level symptoms in patients with major depressive episode and dysthymia, seems of special relevance when assessing suicide risk.
