The intervertebral haemorrhages described by Simon in 1968 as a vital sign of hanging have been verified and endorsed by other authors. They occur in 40-50 % of hanging cases, most frequently in the lumbar spine, in younger age groups, and in cases of free suspension. The haemorrhages are not unique to hanging, but may occur in particular as a result of other traumatic elongation or overextension of the spinal column (e. g. in the course of traffic accidents). In cases of decomposition of the body, "false positive" findings are relatively common. As external findings scarcely provide any reliable vital signs of hanging, there is still a high demand for autopsies. In addition to Simon's bleedings, internal findings which are diagnostically conclusive also include microscopic examinations of the lungs and the neck musculature. More recent findings such as haemorrhages in the back and auxiliary respiratory muscles as well as the intestinal wall, if confirmed, could supplement Simon's bleedings. Frei's fibre sample and evidence of histamine in the ligature mark should not be neglected. Finally, it must be emphasized that the forensic assessment of hanging cases should always be based on a criminological and forensic evaluation of all the circumstances of the offence as well as on post-mortem findings. 相似文献

Transposition of the great vessels (TGV) is a common congenital heart defect that is difficult to diagnose before birth. Antenatal diagnosis is associated with increased survival. Unusual features such as anomalous pulmonary artery origin may delay cyanosis, decreasing clinical suspicion. A three‐week old female infant who had never been cyanotic presented for forensic autopsy due to onset of unresponsiveness at home. History included risk factors for TGV and signs of heart enlargement that were not recognized during life. Cardiac pathology consultation identified D‐type TGV with additional rare anomalies. TGV may present as sudden unexplained infant death (SUID) for forensic autopsy if variant features prevent development of cyanosis. Cardiac pathology consultation is helpful in clarifying these features. 相似文献

Fracture characteristics, reported primarily for the cranium, are valuable indicators of bullet direction. A bullet striking the vault tangentially produces an irregular opening, termed a "keyhole defect." with the circular portion of the defect being the initial point of impact. Identifying this feature in tubular bone (long bone) can also demonstrate bullet direction and the position of the bone at the time of the shooting. This case study involving a tangential shot (i.e., a keyhole fracture) to the humerus demonstrates some of the same fracture mechanics seen in the cranium. 相似文献

On typing the C3-system: Inhibition of the conversion by EDTA-Na2 (chelaplex III) (author's transl)]
By addition of EDTA-Na2 (Chelaplex III) to fresh sera the possibility for typing of C3-polymorphism is prolonged. Using a final concentration of 45.6 mmol EDTA-Na2/l the conversion is inhibited, and the C3 determination in serum by means of high voltage electrophoresis succeeds even after storage at room temperature during 6 weeks. 相似文献

Pipe bombs of steel or PVC fragment in reproducible patterns when similarly configured. The power of the explosion correlates with number, mass, and size of the fragments recovered, where a large number of small, low‐mass fragments indicate a high‐power event and vice versa. In discussing performance, describing pipe fragmentation pattern by fragment weight distribution mapping (FWDM) or fragment surface area distribution mapping (FSADM) was useful. When fillers detonated, detonation velocities of ~4.4 mm/μs were measured. In such cases, side walls of the pipe were thrown first; the average fragment velocity was ~1000 km/s. In deflagrations, the end cap was first thrown; fragment velocities were only ~240 km/s. Blast overpressures varied; at 10 feet, 2 × 12 inch steel pipes containing ~550 g of detonable mixture produced overpressures of 5–6 psi; similar nondetonating pipes produced less than 2 psi. Maximum fragment throw distances were 250–300 m, with an average of ~100 m. 相似文献
