The aim of this article is to find a correlation between height and femur/skull measurements through Computed Tomography (CT) scans and derive regression equations for total skeletal height estimation in the Caucasian population. We selected 200 Caucasian patients from March 2010 to July 2011 who had to perform a CT scan for cancer restaging. The mean age is 64.5 years. Both sexes are represented by the same number of persons. Patients have executed a total body CT scan with contrast; once scan accomplished, we measured height through a digital scales. We analyzed CT scans of each patient, obtaining multiplanar reconstruction in sagittal and coronal planes with 1mm of thickness, and we measured 10 diameters of skull and femur. Then we performed a single and a multiple regression analysis considering the three diameters that better correlated with height. The skeletal diameters with the highest correlation coefficients with stature were femur lengths, length of cranial base (Ba-N), and distance from the posterior extremity of the cranial base to the inferior point of the nasal bone (Ba-NB). Although both femur and skull are skeletal segments used for stature estimation, in our sample femur gave stronger correlation with height than skull. h=35.7+1.48·BaN+2.32·BaNB+2.53·FEM and h=3.06·FEM+72.6 are the formulae that provided the most accurate stature assessment using multiple and single regression analysis respectively. 相似文献

Nerium oleander is a very popular urban ornamental plant in Europe, but it is also extremely dangerous because it contains several types of glycosides, accidental ingestion of which can cause cardiac arrhythmias and even deaths. The rarity of such cases makes it difficult to think of oleander poisoning without evidences that suggest this possibility as the cause of the unexpected death. This report concerns the discovery of the bodies of 2 young people, a man and a woman, in a forest in conditions of extreme malnutrition. Medicolegal investigations showed neither pathologic nor traumatic causes of death, but the presence of vegetal remains in the stomach was noticed. A common toxicological analysis resulted negative, but the implementation of more detailed investigations showed the presence of digoxin in the blood of both cadavers, excluding the possibility of a pharmaceutical provenience of digoxin, this laboratory result was interpreted as evidence of ingestion of oleander, which contains oleandrine, the cross reaction of which with digoxin is widely described in the literature. Identification of the 2 subjects, which occurred after 4 years, strengthened the hypothesis of accidental poisoning by oleander because it was ascertained that the 2 young people were vegans--extreme vegetarians who reject the ingestion of foods of animal origin and live by eating only what they find in nature. 相似文献

Gunshot Residue (GSR) produced by the discharge of a firearm often provides very useful information in criminal investigations in cases involving the use of firearms. Scanning Electron Microscopy equipped with an Energy Dispersive X-ray Spectrometer (SEM-EDS) is typically used worldwide to visualize micrometric particles constituting GSR and to analyse their elemental composition. The 2017 ASTM Standard guide for gunshot residue analysis by scanning electron microscopy/energy dispersive X-ray spectroscopy specifies that “Particles classified as characteristic of GSR will have one of the following elemental compositions: Lead, antimony, barium; Lead, barium, calcium, silicon, tin”. For the first time, the presence of an additional element, such as Sn, plays a key role in ASTM particle classification. It is known that some ammunitions, used for pistols, revolvers and rifles, contain tin foil discs for sealing the primer mixture into the cup, resulting in GSR particles containing Sn. The authors faced some cases in which Sn was unexpectedly found in GSR particles from a 0.22 Long Rifle derringer and from some 12 gauge shotguns. No tin foil discs are used in rimfire ammunitions and there is no published evidence of tin foil discs in shotshell ammunitions. Following a “case by case” approach, experimental research has been carried out to explain how Sn can be present in GSR particles when the last discharged cartridge also does not contain any Sn either in components and in the explosive charges.Moreover, the use of Particle Induced X-ray Emission (PIXE) showed the capability to overcome overlap ambiguity of Sb and Sn peaks in the X-ray spectra, being a possible key issue in real shooting cases if Sn quantities are below the lower limit of SEM detection, especially when Sb is also present. 相似文献

This paper problematizes the fear-based marketing of guns and tasers to both men and women as a function of neoliberalism’s emphasis on consumption as the solution to social problems. Men are marketed dangerous weapons as a way to display their masculinity, while women are told that purchasing guns or tasers is one of the best ways to protect themselves from domestic violence and sexual assault. As the paper shows, that claim is in stark contrast to data about these phenomena, and yet such marketing is often taken as a common sense solution. In addition to detailing why such marketing of weapons is problematic, we offer several recommendations. 相似文献

The authors describe a road accident that occurred in the Trieste region of Italy in 1998, wherein a pedestrian experienced a mortal injury. During the on-site examination, the forensic officer in charge noticed, in addition to dispersed abrasions, bruises, and fractures, an unusual position of the head with a highly unusual motility of the cervical rachis and, above all, an apparent whitish fibrous elastic cord, 7-8 cm long, which came out of the mouth. The cord was found to be a segment of the spinal cord, expelled and driven into the mouth cavity by the impact. This represents an interesting case because of the specific dynamics of the accident and the type of lesion involved. This kind of spinal cord injury, in particular, is infrequent among pedestrians involved in road accidents in comparison with other road casualties. 相似文献

The passage of electric current through the human body causes variable harm, ranging from loss of consciousness to death caused by paralysis of the bulbar nerve centers. This report describes a fatal case caused by an illegal fishing practice involving stunning fish with electric shocks produced by an electric generator carried through the water inside the carcass of an old refrigerator to keep it afloat. This occurrence is unusual because of the circumstances giving rise to the use of electric current and the cause of death, which resulted from the combination of the electric current produced by the generator and the saltwater, bringing about death by drowning. 相似文献
