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

In contrary to "physical restraint", describing a fixed body position due to external devices, "positional restraint" is defined as an abnormal body position, resulting from accidental fixation under unfortunate circumstances. We report on a remarkable case of positional asphyxia of an alcoholised young man after a fall down a staircase. On external examination, the body showed petechiae of the conjunctivae and oral mucosa, abrasions on the left zygomatic region and scratch marks, respectively. Neither broken fingernails, etc. nor signs of external violence against the neck were found. Autopsy revealed haemorrhages in the praevertebral cervical musculature and Simon's sign. Haemorrhagic pulmonary edema and cerebral edema were observed; blood alcohol concentration: 2.60 g/l, urine alcohol concentration: 3.26 g/l. As cause of death, positional asphyxia after blunt head trauma has to be considered as well as lethal ethanol intoxication. To us, alcoholisation attributed to the fall and together with unconsciousness following blunt head trauma circumvented self-rescue efforts, and therefore, aggravated the potentially lethal impact of positional restraint. 相似文献

In cases of suicidal gunshots, the capacity to act may be preserved for a certain period of time, so that the suicide may be completed with another method. In the presented case a 74-year-old man was found hanged on the first floor of his house with two gunshot wounds in the chest. Both on the ground and the upper floor traces of suicidal acts were detected. As shots to the precordial region suggest rapid incapacitation, a suicide extending over two floors seemed almost impossible without knowledge of the cause of death and evaluation of the ability to act. The autopsy findings confirmed vital signs of hanging. Moreover, a through-and-through gunshot wound of the chest and abdomen affecting the spleen and a shot lodged in the body without injuring the lung were found. The injury findings thus sufficiently explained the preserved ability to act. The presented case shows characteristics of a complex suicide not yet described so far, but could be clearly classified as suicide in congruity with the pertinent literature. 相似文献

An outwardly mummified and inwardly badly decomposed body was found in a garage. At autopsy, no injuries were detected. Apart from coronary heart disease, with an old myocardial scar and a hepatic steatosis, the most striking finding was a large intracranial epidural hemorrhage situated at the left frontal lobe. As a relevant traumatic genesis could be ruled out, we deemed this a nontraumatic epidural hematoma. This finding is extremely rare. Several underlying disorders have been discussed as causes of spontaneous epidural hematomas. In this presented case, the authors discuss possible etiological factors. 相似文献

The most popular handgun in Brazil is the single round-barrel caliber 0.38 revolver. In recent years, however, owing to the modernization of police arms and their availability on the legal and illicit markets, pistols have become increasingly popular and currently represent about 20% of police seizures. In a previous paper we presented a novel collection method for gunshot residues (GSR) using a sampling procedure based on ethylenediamine-tetraacetic acid (EDTA) solution as a complexing agent on moistened swabs with subsequent detection using sector field-high resolution-inductively coupled plasma-mass spectrometry (SF-HR-ICP-MS). In the present paper, we discuss the capability of this methodology to identify antimony (Sb), barium (Ba) and lead (Pb) on the hands of volunteers after shot tests with 9 mm and 0.40 in. caliber pistols. Two types of munitions were tested: 9 mm Taurus and clean range. The use of a technique with high sensitivity, such as SF-HR-ICP-MS, permits the identification of low concentrations (less than 1 microg/L) of metals in firearm residue and constitutes a powerful tool in forensic science. We also discuss the importance of the sampling procedure, including collection from a different body part than the gun hand of the suspect. Comparison of the analytical data obtained allows clear discrimination between samples from the hands of shooters and non-shooters. 相似文献

The examination of traffic accidents is daily routine in forensic medicine. An important question in the analysis of the victims of traffic accidents, for example in collisions between motor vehicles and pedestrians or cyclists, is the situation of the impact. Apart from forensic medical examinations (external examination and autopsy), three-dimensional technologies and methods are gaining importance in forensic investigations. Besides the post-mortem multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) for the documentation and analysis of internal findings, highly precise 3D surface scanning is employed for the documentation of the external body findings and of injury-inflicting instruments. The correlation of injuries of the body to the injury-inflicting object and the accident mechanism are of great importance. The applied methods include documentation of the external and internal body and the involved vehicles and inflicting tools as well as the analysis of the acquired data. The body surface and the accident vehicles with their damages were digitized by 3D surface scanning. For the internal findings of the body, post-mortem MSCT and MRI were used. The analysis included the processing of the obtained data to 3D models, determination of the driving direction of the vehicle, correlation of injuries to the vehicle damages, geometric determination of the impact situation and evaluation of further findings of the accident. In the following article, the benefits of the 3D documentation and computer-assisted, drawn-to-scale 3D comparisons of the relevant injuries with the damages to the vehicle in the analysis of the course of accidents, especially with regard to the impact situation, are shown on two examined cases. 相似文献

The entrepreneurial puzzle: explaining the gender gap 总被引:1,自引:0,他引:1
We document the substantial gender gap that exists among university scientists with regard to entrepreneurial activity using
a variety of measures and explore factors leading to the disparity. We focus particularly on the biomedical sciences. The
contextual explanation that women are under-represented in the types of positions from which faculty typically launch entrepreneurial
activity is the most obvious. But the data suggest that for the biomedical sciences context is not sufficient in explaining
the entrepreneurial gap. We look elsewhere to factors affecting supply and factors affecting demand. The former include gender
differences in attitudes towards risk, competition, “selling” of “science,” type of research and geographic location. The
latter include the role of networks, preferences of venture capitalists and “gender discounting.” We explore the associated
hypotheses. We provide few tests and conclude that the research agenda is wide open and interesting.
