Staphylococcal scalded skin syndrome mimicking child abuse by burning

Determining the cause for the sudden death in young adults tends to be complex and difficult. Two cases of death of young people were autoptically investigated who died suddenly while carrying out their hobbies (a 22-year-old male musician and a 20-year-old female dancer). In both cases neither the police investigation, the autopsy, nor the toxicological investigations gave any relevant results. However, when investigating the histology fatty and fibrotic tissue in the right ventricle of the myocardium were found, whereas the myocytes proved to be degenerated--typical for arrhythmogenic right ventricular cardiomyopathy (ARVC). It is important to consider the possibility of heart rhythm failure if a clear reason for sudden death in young adults cannot be detected. Heart rhythm failure often involves the genetic background of the case, which suggests that genetic analysis should be carried out as a supportive means of diagnostics.     

DETECHIP®: A Sensor for Drugs of Abuse*

Abstract: The design and preliminary characterization of a novel sensor for drugs of abuse, DETECHIP^®, is described in this proof‐of‐concept note. Combining both colorimetric and fluorimetric assays, DETECHIP^® is suitable for lab and field use. More than a conventional spot test which provides a single “yes or no” answer, DETECHIP^® provides twenty responses for a more complete characterization of suspect material. This is accomplished by visually noting colorimetric and fluorescent changes of carefully selected dyes upon the addition of test analytes, including drugs of abuse, with respect to controls. Color and fluorescence changes are recorded numerically so that a 20 digit identification code can be constructed for comparison of test analytes and known compounds. DETECHIP^® is applicable to a variety of drugs, both plant‐derived and synthetic, addressing the need to use several different spot tests simultaneously for a single sample.     

Putting the ‘rights‐based approach’ to development into perspective

This paper seeks to unravel some of the tangled threads of contemporary rights talk. For some, the grounding of rights‐based approaches in human rights legislation makes them distinctively different to others, lending the promise of re‐politicising areas of development work—particularly, perhaps, efforts to enhance participation in development, that have become domesticated as they have been ‘mainstreamed’ by powerful institutions like the World Bank. Others complain that like other fashions, the label ‘rights‐based approach’ has become the latest designer item to be seen to be wearing, and has been used to dress up the same old development. We pose a series of questions about why rights have come to be of interest to international development actors, and explore the implications of different versions and emphases, looking at what their strengths and shortcomings may come to mean for the politics and practice of development.     

Effectiveness of pupil diameter in a probable‐lie comparison question test for deception

Purpose. There were three objectives of this study: (1) To assess the possibility of using pupil diameter as an index of deception in the context of a comparison question polygraph test. (2) To determine if pupil diameter would make a significant contribution to an optimal multivariate classification equation in combination with the traditional predictor variables used in field polygraph practice. (3) We explored the possibility of replacing one or more of the traditional predictor variables with pupil diameter. Methods. We used a laboratory mock crime experiment with 24 participants, half of whom stole $20 (US) from a secretary's purse. Participants were tested with a comparison question test modelled after standard field practice. Physiological measures were taken with laboratory quality instrumentation. Features were extracted from the physiological measures. Those features were subjected to a number of different statistical analyses. Results. Innocent participants showed larger increases in pupil diameter in response to probable‐lie questions than to relevant questions. Guilty participants did not show differential responding to the question types. The additional of pupil diameter to a multivariate classification model approached, but did not reach significance. Subsequent analyses suggest that pupil diameter might be used to replace the traditional relative blood pressure measure. Conclusions. Pupil diameter was found to be a significant predictor variable for deception. Pupil diameter may be a possible replacement for the traditional relative blood pressure measure. Additional research to explore that possibility would seem to be warranted.
