Ärztliche Untersuchungsbefunde bei polizeilich auffälligen Personen unter dem Einfluss von Amphetaminderivaten

Das Auftreten von Psychostimulantien im Straßenverkehr und eine Beeinträchtigung der Fahrtüchtigkeit durch diese spielt in Deutschland zunehmend eine wichtige Rolle. Das Ziel der hier vorliegenden Arbeit war es retrospektiv die dokumentierten Ausfallserscheinungen von Personen unter Einfluss von Amphetaminderivaten anhand von ärztlichen Untersuchungsbögen, die bei polizeilich angeordneten Blutentnahmen ausgefüllt werden, des Zeitraums 2001 bis 2005 in Rheinland-Pfalz zu untersuchen. Aufgrund der hohen Fallzahlen konnten sehr strenge Auswahlkriterien angewandt werden, sodass lediglich reine Amphetaminderivat-Intoxikationen (Amphetamin, Methamphetamin, MDA, MDMA, MDE, MBDB) bei 923 Personen untersucht werden konnten. Es zeigten sich als verkehrsrelevante Beeinflussung die Erweiterung der Pupille mit einer geringeren Lichtreagibilität, eine Verlängerung des Drehnachnystagmus sowie eine Unsicherheit beim Rombergtest. Eine Dosis-Wirkungs-Beziehung konnte lediglich bei der Pupillenweite ansatzweise gefunden werden. Bei MDMA zeigte sich ein deutlich stärkerer Einfluss auf die Pupillenweitenregulation als bei Amphetamin. Die zur Detektion von alkoholbedingten Ausfallserscheinungen sinnvollen Gleichgewichts- und Koordinationstests waren im Falle der hier betrachteten Psychstimulantien nicht aussagekräftig. Es erscheint empfehlenswert die durchgeführten Untersuchungen mit Hilfe von einheitlichen Lichtverhältnissen und festgelegten Untersuchungsprozedere zu standardisieren ggf. auch durch die Einführung der Videookulographie. Die Einführung eines Reaktionstests sollte in Erwägung gezogen werden.

Using Micro-Gravity Techniques to Map Alluvium Thickness and Pleistocene Location of the West Branch of the Susquehanna River Near Muncy, Pennsylvania

Laurentide glaciation during the early Pleistocene (~970 ka) dammed the southeast-flowing West Branch of the Susquehanna River (WBSR), scouring bedrock and creating 100-km-long glacial Lake Lesley near the Great Bend at Muncy, Pennsylvania (Ramage et al., 1998). Local drill logs and well data indicate that subsequent paleo-outwash floods and modern fluvial processes have deposited as much as 30 meters of alluvium in this area, but little is known about the valley fill architecture and the bedrock-alluvium interface. By gaining a greater understanding of the bedrock-alluvium interface the project will not only supplement existing depth to bedrock information, but also provide information pertinent to the evolution of the Muncy Valley landscape. This project determined if variations in the thickness of the valley fill were detectable using micro-gravity techniques to map the bedrock-alluvium interface. The gravity method was deemed appropriate due to scale of the study area (~30 km2), ease of operation by a single person, and the available geophysical equipment. A LaCoste and Romberg Gravitron unit was used to collect gravitational field readings at 49 locations over 5 transects across the Muncy Creek and Susquehanna River valleys (approximately 30 km2), with at least two gravity base stations per transect. Precise latitude, longitude and ground surface elevation at each location were measured using an OPUS corrected Trimble RTK-GPS unit. Base stations were chosen based on ease of access due to the necessity of repeat measurements. Gravity measurement locations were selected and marked to provide easy access and repeat measurements. The gravimeter was returned to a base station within every two hours and a looping procedure was used to determine drift and maximize confidence in the gravity measurements. A two-minute calibration reading at each station was used to minimize any tares in the data. The Gravitron digitally recorded finite impulse response filtered gravity measurements every 20 seconds at each station. A measurement period of 15 minutes was used for each base station occupation and a minimum of 5 minutes at all other locations. Longer or multiple measurements were utilized at some sites if drift or other externalities (i.e. train or truck traffic) were effecting readings. Average, median, standard deviation and 95% confidence interval were calculated for each station. Tidal, drift, latitude, free-air, Bouguer and terrain corrections were then applied. The results show that the gravitational field decreases as alluvium thickness increases across the axes of the Susquehanna River and Muncy Creek valleys. However, the location of the gravity low does not correspond with the present-day location of the West Branch of the Susquehanna River (WBSR), suggesting that the WBSR may have been constrained along Bald Eagle Mountain by a glacial lobe originating from the Muncy Creek Valley to the northeast. Using a 3-D inversion model, the topography of the bedrock-alluvium interface was determined over the extent of the study area using a density contrast of -0.8 g/cm3. Our results are consistent with the bedrock geometry of the area, and provide a low-cost, non-invasive and efficient method for exploring the subsurface and for supplementing existing well data.
