Sudden cardiac death in a 5-year-old girl associated with parvovirus B19 infection

We report on a 5-year-old girl who suddenly collapsed and died while dancing at a family party. Histological examination of the heart including the cardiac conduction system revealed lymphocytic infiltrations of the sinu-atrial node and perivascular infiltration in the atrio-ventricular region. Additionally, foci of mononuclear infiltrates were observed in the myocardium. Consequently, myocarditis was diagnosed as cause of death. The child also had lymphocytic conjunctivis, parotitis and tracheitis. Evaluation of infections by means of nested polymerase chain reaction revealed parvovirus B19 DNA (PVB19) in tissue samples of the trachea.     

Isomeric fluoro-methoxy-phenylalkylamines: a new series of controlled-substance analogues (designer drugs)

An impressively large number of clandestinely produced controlled-substance analogues (designer drugs) of amphetamine with high structural variety have been encountered in forensic samples in recent years. The continuous designer drug exploration and their widespread consumption results in an increasing number of reports regarding abuse and intoxication. This study presents the analytical properties of a series of new fluoro-methoxy-substituted controlled-substance analogues of amphetamine. Three ring positional isomeric fluoroamphetamines, two isomeric fluoromethoxyamphetamines, two N-alkyl 4-fluoroamphetamines, and one 4-fluorophenylbutan-2-amine were identified and differentiated by gas chromatography-mass spectrometry (GC-MS), 1H- and 13C-nuclear magnetic resonance (NMR), and gas chromatography-infrared spectroscopy (GC-IR). The regioisomeric 2-, 3-, and 4-fluoroamphetamines and the regioisomeric fluoro-methoxyamphetamines show virtually identical mass spectra so that this method is insufficient to discriminate between these closely related compounds. The mass spectra of the acetylated compounds allowed a differentiation of the 4-fluoroamphetamine from its regioisomeric 2- and 3-fluoroamphetamines. The gas chromatographic properties of the three regioisomeric fluoroamphetamines and their acetylated and trifluoroacetylated derivatives are also so similar that a complete separation of these compounds could not be achieved under GC-MS conditions. The two isomeric compounds 5-fluoro-2-methoxyamphetamine and 3-fluoro-4-methoxyamphetamine on the other hand showed significant different gas chromatographic retention times so that a separation was uncomplicated. The trifluoroacetylation of these compounds proved to be an effective method for their mass spectral differentiation. Gas chromatography-infrared spectroscopy and 1H- and 13C-nuclear magnetic resonance allowed an unequivocal differentiation of all studied regioisomeric fluoroamphetamines and fluoro-methoxyamphetamines.     

ACTBP2 (alias ACTBP8) is localized on chromosome 6 (band 6q14)

The locus ACTBP2 (SE33) is localized on chromosome 6 (band 6q14). This has been demonstrated by typing a large Caucasoid three-generation kindred of Austrian origin for SE33 and several chromosome 6 markers.     

Christian Ehrenfried Eschenbach (1712-1788)--a pioneer of legal medicine in German universities

Christian Ehrenfried Eschenbach (1712-1788) belongs to the forerunners of the embossed natural science scholars of legal medicine in Germany. As a principal re-elected 11 times and dean of the medical faculty at Rostock University he defended academic positions in difficult times. His bibliography comprises numerous text books, e.g. on surgery, anatomy, pathology and obstetrics as well as various fields of mathematics. His Medicina legalis (1746 and 1775) belongs to the first systematic editions of forensic medicine in the German-speaking community. Thanks to his extensive practical experience as a physician and public health officer he took a very progressive position on questions of forensic medicine, issues of professional ethics in medicine and the assessment of injuries. He has wrongly been forgotten.
