Correlations on radioimmunoassay, fluorescence polarization immunoassay, and enzyme immunoassay of cannabis metabolites with gas chromatography/mass spectrometry analysis of 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid in urine specimens.

Results obtained from three commercial immunoassay kits, Abuscreen, TDx, and EMIT, commonly used for the initial test of urine cannabinoids (and metabolites) were correlated with the 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid (9-THC-COOH) concentration as determined by GC/MS. Correlation coefficients obtained based on 26 (out of 1359 total sample population) highly relevant samples, are 0.601 and 0.438 for Abuscreen and TDx. Correlation coefficients obtained from a parallel study on a different set of 47 (out of 5070 total sample population) highly relevant specimens are 0.658 and 0.575 for Abuscreen and Emit. The immunoassay concentration levels, that correspond to the commonly used 15 ng/ml GC/MS cutoff value for 9-THC-COOH, as calculated from the regression equations are 82 ng/ml and 75 ng/ml for TDx and EMIT and 120 ng/ml and 72 ng/ml for Abuscreen manufactured at two different time periods. The difference of these calculated corresponding concentrations provides quantitative evidence of the reagent specificity differences.     

Hazards of mattresses, beds and bedding in deaths of infants

Of 52 infants who had died suddenly and were referred to autopsy, nine had lain on adult water beds for the first time; five had died as a result of accidents; two had died on water beds; two were in beds with widely spaced slats; and one had died as a result of strangulation. Three deaths were due to overlying. Three other infants had been placed on sheepskin rugs for the first time and were found dead shortly thereafter. These infants ranged in age from 2 to 9 months, except for a severely mentally retarded nine-year-old with spastic paraplegia. We believe that a general warning should be issued concerning water beds and that soft bedding should not be used for infants. Infants should not be placed unattended or left to sleep on water beds; only beds recommended for infants should be used. Overlying of a young infant is most likely to occur on a water bed, or if the parent is obese or has consumed alcohol.     

A case of external beveling with an entrance gunshot wound to the skull made by a small caliber rifle bullet.

The external beveling caused by an entrance gunshot wound to the skull has not been completely explained, but the mechanism is probably a combination of several factors including the angle of shot, twisting force of a rotating bullet, blow-back effect, velocity, shape and size of the bullet, outspread of the kinetic energy from the bullet, and resistance of the skull.     

Auswirkungen eines deutschen Gleichstellungsbescheids auf die Eigenschaft als begünstigter Behinderter

Sowohl das deutsche Schwerbesch?digtengesetz als auch das ?sterr Invalideneinstellungsgesetz anerkannten in den jeweils 1964 noch geltenden Fassungen als Begünstigte nur bestimmte Personengruppen, wie Kriegsopfer und deren Hinterbliebene, nationalsozialistisch Verfolgte und deren Angeh?rige (in Deutschland zus?tzlich: besatzungsgesch?digte Personen) sowie durch Arbeitsunfall und Berufskrankheit gesch?digte Personen und mittlerweile auch Zivilblinde. Art 19 Abs 2 des am 1. 9. 1964 in Kraft getretenen Vertrags zwischen der Republik ?sterreich und der Bundesrepublik Deutschland über Kriegsopferversorgung und Besch?ftigung schwer Gesch?digter (BGBl 1964/218) kann aus diesem Grund einem deutschen Bescheid oder einer deutschen Bescheinigung nur dann bindende Wirkung verleihen, wenn er sich auf eine dieser historischen Personengruppen bezieht.

Managing incidental findings in human subjects research: analysis and recommendations.

No consensus yet exists on how to handle incidental findings (IFs) in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are findings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed.     

Der Feinstaubschleier lichtet sich – rechtlich II – zugleich Anmerkung zum Urteil des Bundesverwaltungsgerichts vom 27.9.2007 – 7 C 36.07

Zusammenfassung Nur selten schafft es eine verwaltungsgerichtliche Entscheidung an die erste Stelle der ARD-Tagesschau um 20 Uhr. Dem Urteil des BVerwG vom 27.9.2007 ist das gelungen. Es liefert die Antwort auf eine Frage, die sich mancher TV-Zuschauer und Zeitungsleser seit der ersten H?lfte des Jahres 2005 gestellt haben mag. Einer aufgeregten Medienberichterstattung war damals zu entnehmen, dass der gerade verbindlich gewordene Feinstaubgrenzwert vielerorts überschritten werde und davon Betroffene Erkrankungen des Herz-Kreislauf-Systems und der Atemwege, ja sogar eine Verkürzung ihrer Lebenserwartung zu befürchten h?tten. Die Frage die sich stellte: Was kann ein Betroffener dagegen unternehmen?
