We report the case of attempted suicide with amlodipine, chlorthalidone and mefenamic acid and subsequent medical intensive care measures which resulted in total recovery of a 42-year-old male. After admission to the medical intensive care unit the intoxicated patient was deeply hypotensive and needed fluid replacement, dobutamine and norepinephrine. Additionally insulin and calcium gluconate were given. Since hypotension persisted and the patient developed oliguria, terlipressin was applied and finally showed an effect on blood pressure and on urinary output. A volume overload of 7 L in the first 24 h resulted in a pulmonary edema. The patient was started on non-invasive ventilation with continuous positive airway pressure (CPAP) and frusemide was added to the therapy with good success. Quantitative determination of amlodipine in plasma samples was performed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The highest amlodipine concentrations was measured in the plasma sample collected approximately 8 h after ingestion of the drug, and was 393 microg/L. Four days later, it was possible to stop the treatment with catecholamines, at that time the amlodipine plasma concentration had declined to 132 microg/L, still tenfold higher than therapeutic (5-18 microg/L). Elimination half-life of amlodipine is approximately 55 h. After 6 days in the intensive care unit the patient was transferred to psychiatric treatment. Intensive care management and plasma levels in this intoxication case are compared to data from literature on other cases. 相似文献

A bench study was performed to investigate the potential of air bubbles entering a central vein via a central venous catheter to ascend retrograde to the brain. The results support the hypothesis that air bubbles may rise retrograde against the venous blood flow, depending on bubble size, central vein diameter and cardiac output. A review of radiological findings in published case reports indicates that the occurrence of retrograde cerebral air embolism is underestimated. 相似文献

In order to gain information regarding the ethnic origin of an unknown offender in a murder case it was necessary to sequence the HV1 and 2 regions of the mitochondrial DNA (mtDNA). The only evidentiary material that could be linked to the suspect was DNA, extracted from spermatozoa after differential lysis. The observed mtDNA sequences were identical to the sequences of the victim. Therefore, we had to check if this was a coincidence or the result of a technical limitation of the testing procedure. Subsequently, we performed a systematic study. In cases with complete separation of sperm and female cells it wasn't possible to obtain a mtDNA sequence for the sperm fraction. This phenomena is based on the loss of the sperm's flagellum and mid-piece during the first lysis step and a concomitant loss of the sperm's mitochondria. In our murder case, a minor carry-over of female cells to the sperm fraction was responsible for the sequencing result. 相似文献

Abstract: The essay begins with a recapitulation of core institutional properties of the European Union as they have evolved over several decades. The leading insight deriving from this exercise is that European social policy will always, for all practical purposes, be made simultaneously at two levels, a supranational one and a national one, and will be shaped by complex interactions between them and among the national systems situated in the integrated market economy of the Union. Proceeding from here, the remainder of the paper examines the two levels of social policy-making, beginning with the supranational and moving on to the national, in an effort to identify the kinds of policies that are most likely to emerge given the constraints and opportunities offered by the institutional framework. 相似文献

Time-dependent immunohistochemical detection of proinflammatory cytokines (IL-1beta,IL-6, TNF-alpha) in human skin wounds 总被引:2,自引:0,他引:2
Grellner W 《Forensic science international》2002,130(2-3):90-96
The proinflammatory cytokines interleukin-1beta (IL-1beta), interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha) hold important functions in the early and late courses of inflammation, trauma and wound healing. In the present study, human skin wounds due to sharp force (n = 105) were collected during surgery and autopsy. The wound age mainly varied from several minutes to 5 h, some specimens aged up to 6 weeks. Control specimens from uninjured skin were available in each case. After preparation of cryostat sections, immunohistochemistry was performed according to the APAAP technique, using monoclonal and polyclonal antibodies. The results were evaluated semiquantitatively. All markers were weakly expressed in normal human skin constitutively. However, the staining pattern changed significantly in vital wounds concerning epidermal layers, subepidermal cells, vessels and sweat glands. IL-1beta and IL-6 showed enhanced expression after 15 and 20 min at the earliest (increase of epidermal reactivity). After 30-60 and 60-90 min, respectively, marked expression was observed with these markers. Similar alterations were detectable with TNF-alpha after 15 and 60-90 min. The reactivity of all three markers persisted over several hours, then decreased to basal levels again and sometimes reappeared after days and in granulation tissue. Leukocytes reacting with IL-1beta and IL-6 appeared after approximately 2 h. CONCLUSION: proinflammatory cytokines can serve as a useful tool for the estimation of vitality and wound age, in particular in the early post-traumatic interval prior to leukocyte reaction. Autolysis did not play a role in the samples investigated (postmortem interval up to 8 days). Problems could sometimes rise from constitutive expression. Therefore, it is recommended to examine control samples from the same individual and to compare the reactivity with wound specimens. 相似文献

The remediation processes in psychosocial crisis intervention were modeled focusing on cognitive orientation. Frequent observations and subsequent process modeling constitute a novel approach to process research and reveal process-outcome associations. A sample of 40 inpatients who were assigned to treatment in a crisis intervention unit was monitored in order to study the process of crisis intervention. The process data consisted of patients' self-ratings of the variables mood, tension, and cognitive orientation, which were assessed three times a day throughout hospitalization (M = 22.6 days). Linear time series models (vector autoregression) of the process data were computed to describe the prototypical dynamic patterns of the sample. Additionally, the outcome of crisis intervention was evaluated by pre-post questionnaires. Linear trends were found pointing to an improvement of mood, a reduction of tension, and an increase of outward cognitive orientation. Time series modeling showed that, on average, outward cognitive orientation preceded improved mood. The time series models partially predicted the treatment effect, notably the outcome domain "reduction of social anxiety," yet did not predict the domain of symptom reduction. In conclusion, crisis intervention should focus on having patients increasingly engage in outward cognitive orientation in order to stabilize mood, reduce anxiety, and activate their resources. 相似文献

Since the introduction of the European Early Warning System in 2005, >700 new psychoactive substances (NPS) have been listed. This review article presents for the first time the Swiss narcotic law in perspective of scheduling of NPS, and compares it to the regulations of the German speaking neighbours Austria and Germany.The Swiss way is a fast and effective way for scheduling NPS, with the purpose to restrict drug trafficking and for controlling the NPS drug market: the legal basis for scheduling substances of abuse is the “Law about narcotics and psychotropic substances” (BetmG, SR 812.121), which includes the “narcotic law directory (BetmVV-EDI, SR 812.121.11) suitable for listing all controlled substances. The BetmVV-EDI, SR 812.121.11 contains seven indices, with index e specifically designed for the fast scheduling of NPS. Newly appearing NPS can either be controlled under a structure analogues definition or by listing single substances. The list of single substances is updated at least once per year, and structure analogues definitions can be implemented, in order to keep track with new developments on the NPS market. The latest version from November 30th 2018 contains ten different structure analogue definitions and 207 single substances. Requirements to list NPS are their appearance on the NPS market, suspected psychotropic effects and their suggestions by Forensic professionals. As soon as substances are newly placed, on Schedule I of the 1961 Convention or Schedule II of the 1971 Convention by the Commission on Narcotic Drugs of the World Health Organization they can easily be transferred from index e to index a-d of the BetmVV-EDI, SR 812.121.11. The Austrian law uses a structure analogue and single substances approach (introduced in 2012, one update in 2016), whereas the German NPS law (established in 2016, no update yet) only lists two structure-analogue-definitions. All three legislations have defined which core structures, kinds and sites of substitutions are regulated. 相似文献

Etienne Laspeyres (1834–1913) is today best known for the price index number formula named after him, but arguably his main contribution to economic literature is his Geschichte der Volkswirthschaftlichen Anschauungen der Niederländer und ihrer Litteratur zur Zeit der Republik (1863). This sketch sets out to consider whether this work, the contents of which will be briefly outlined and placed into context, can be considered a Law & Economics classic, in the sense of the biographical part of the Elgar Companion to Law and Economics (1999), as well. While interesting in its own right, the discussion of this question also serves as an inroad into the discussion of exactly what type of combination of law and economics is necessary to be considered part of Law & Economics as a specific mode of scholarly inquiry. 相似文献

Both in the United States and in Europe, there is a debate on methodology in legal research. Doctrinalists and multidisciplinarians appear to be in different camps fighting over the ‘true nature’ of legal scholarship. We wonder where this renewed attention for methodology is coming from and what is behind it. Should European legal scholars follow certain colleagues in the United States who believe that doctrinal research is dead and should we all engage in law and … research now? If not, does this imply that there is nothing wrong with mainstream European doctrinal legal scholarship? We believe the latter is not the case. Our hypothesis is that an ongoing instrumentalisation of law and legal research decreases the attention for methodology, for theory building, and for keeping enough professional distance to one's object of research. This threatens to result in a creeping process of herd behaviour, in copy pasting the methodology of judicial lawmaking to legal scholarship and in a lack of transparency and methodological justification in scholarly legal publications. What is desperately needed is more reflection on methodology and theory building in European legal scholarship. 相似文献
