Pink teeth have most often been observed in victims of drowning but have also been reported in subjects who died suddenly and unnaturally. There is general agreement that there is no obvious connection between the occurrence of pink teeth and the cause of death, but the condition of the surroundings (especially humidity) must certainly play an important role in the development of the pink-tooth phenomenon. The frequency and distribution of postmortem pink coloration of the teeth have been studied among a representative sample of 52 cadavers. All the bodies were victims of a single shipwreck that occurred on March 13, 1997, in the middle of the Otranto Canal (Mediterranean Sea). The bodies were recovered from the seawater after approximately 7 months. A distinct pink coloration of the teeth was found in only 18 cadavers (13 females and 5 males) of ages ranging between 13 and 60 years. The phenomenon was more pronounced in younger individuals due to age-related changes of the root canal, less penetrable by the pigment responsible for the postmortem pink staining. By histochemical methods and autofluorescence, hemoglobin and its derivatives have been identified as the most likely pigments responsible for this postmortem process that can be considered analogous to postmortem lividity. These data are consistent with previous reports on pink teeth, indicating that the diffusion of the blood in the pulp into the dentinal tubules causes the red discoloration of the teeth. Based on the results, the pigmentation is more prominent on the teeth with single roots rather than in the posterior teeth with multiple roots. 相似文献

In the archeological site of the early Christian Episcopal complex of Saint Peter, in Canosa di Puglia (Bari, Italy), during the operations of archaeological excavations, tombs were discovered. They were dated between the sixth and seventh centuries ad with carbon 14 methodology. Five skeletons were found in the 5 tombs: 28A: male individual, 43 years old. The height was 170 cm; the biomass was 65.7 kg. The analysis of the bones indicated several noteworthy pathologies, such as a number of hypoplasia lines of the enamel, the presence of Schmorl hernias on the first 2 lumbar vertebrae, and the outcome of subacromial impingement syndrome. 28E was a male individual, with a biologic age of death of between 44 and 60 years. The height was 177 cm. He had a posttraumatic fracture callus of the medial third of the clavicle, with an oblique fracture rima. 29B was a female individual, 44-49 years old. The height was 158.8 cm; the biomass was 64.8 kg. There was Wells bursitis on the ischial tuberosity on both sides. 29E was a male individual, 45-50 years old. The height was 169.47 cm; the biomass was 70.8 kg. The third and the fourth vertebrae showed Baastrup syndrome (compression of the vertebral spine). There were radiologic signs of deformity on the higher edge of the acetabula and results of frequent sprains of the ankles. 31A was a male individual, 47-54 years old. The height was 178.65 cm; the biomass was 81 kg. The vertebral index showed a heavy overloading in the thoracic lumbar region. There were bony formations under the periosteum on both on the higher and medium facets of the first metatarsus and on the higher and lateral facets of the fifth metatarsus on both sides. As the topography indicates, these small ossifications coincided with the contact points between the back of the foot and parts of the upper shoe. From the osseous remains, in particular from the teeth (central incisors), the DNA was extracted and typed to identify potential family ties among all the subjects. The extraction technique used came from the DNA Promega technique, partially modified by the authors. Stay times of the sample in the extraction buffer were increased and were increased the polymerase chain reaction (PCR) cycles. 相似文献

We performed an experimental investigation to assess whether the “restricted auction” mechanism proposed by Berkovitch, Israel
and Zender in 1997 works effectively as an optimal bankruptcy law or not. An optimal bankruptcy law is a commitment device
that implements efficient choices both before (ex ante) and after (ex post) financial distress, even if moral hazard is binding.
We designed an experiment focused on ex ante efficiency and we found that the restricted auction mechanism was able to direct
an optimal amount of effort toward entrepreneurial activities. This result confirms the theoretical predictions. Nonetheless,
we found that under a plain unrestricted auction mechanism our experimental subjects chose to allocate into their firms a
larger amount of effort than that predicted by theory. Although difficult to justify on theoretical grounds, this experimental
evidence is robust. Our behavioral interpretation is that this result is due to “moral sentiments”, such as the natural propensity
of subjects toward socially desirable behaviors. In fact, we show that it vanishes once these motives are removed. 相似文献

The radiological search for GSR is crucial in burnt material although it has been rarely tested. In this study, thirty‐one bovine ribs were shot at near‐contact range and burnt to calcination in an oven simulating a real combustion. Computed tomography (CT) and magnetic resonance (MR) were performed before and after carbonization and compared with former analyses with DR (digital radiography); thus comparing the assistance, the radiological methods can provide in the search for GSR in fresh and burnt bone. DR demonstrated the greatest ability in the detection of metallic residues, CT showed lower abilities, while MR showed a high sensitivity only in soft tissues. Thus, DR can be considered as the most sensitive method in the detection of GSR in charred bones, whereas CT and MR demonstrated much less reliability. Nonetheless, the MR ameliorates the analysis of gunshot wounds in other types of remains with large quantities of soft tissues. 相似文献

The discovery of mummified bodies in domestic settings is not unusual in the medico‐legal context. It is often a marker of social isolation, even in our urban modern society, and usually occurs among elderly people living alone or in precarious conditions. However, bereaved subjects can sometimes be found managing their grief by deliberately keeping the corpses of their loved ones at home. Investigation of these atypical cases can be challenging and often requires a multidisciplinary effort by different forensic specialists. We report two cases of people who lived for several months with the mummified remains of a relative. In both cases, the judge ordered a forensic psychiatry assessment of the survivors’ competency and the reasons for this peculiar behavior, which is regarded as abnormal in our society. Case 1 describes a shared psychosis, which developed out of a condition of extreme seclusion of the entire family. Case 2 shows that even a mild personality disorder on which a series of traumatic events operates can trigger psychotic decompensation, causing extreme denial of the reality of death. The analysis of these cases contributes to our knowledge of the scantly studied phenomenon of “Living with the Dead” and raises questions about the psychopathology behind it. It is useful to identify subjects who are more prone to developing this “deviant” behavior, in order to distinguish people with mental illness from those who merely want to profit from the death of a loved one. 相似文献

One Hundred and One Cases of Plastic Bag Suffocation in the Milan Area Between 1993 and 2013—Correlations,Circumstances, Pathological and Forensic Evidences and Literature Review 下载免费PDF全文
Graziano Domenico Luigi Crudele M.D. Domenico Di Candia B.Sc. Guendalina Gentile B.Sc. Matteo Marchesi M.D. Alessandra Rancati M.D. Riccardo Zoja M.D. Ph.D. 《Journal of forensic sciences》2016,61(2):361-366
Plastic Bag Suffocation is a rare cause of death in developed countries and almost unknown in the rest of the world. This study aims to retrospectively evaluate cases of PBS _asphyxia in Milan's Department of Legal Medicine from 1993 to 2013. Cases were selected from the database of 21,472 autopsies performed in the considered timeframe. One hundred and one cases were considered to be cases of Plastic Bag Suffocation, comprised of 100 suicides, no accidental events and 1 homicide. The most relevant elements pertaining to this type of death were evaluated for both the corpses and the crime scenes. From this study the typical PBS victim is an adult male, aged 52.3 years on average, depressed or afflicted by chronic or terminal diseases, and found at home. In 42.6% of cases, the victims were found with the plastic bag still positioned over their head, fastened by tying. Also common among these cases are drugs, alcohol and chemical abuses. According to the collected data, it is impossible to outline a pathognomonic detrimental background that leads to this cause of death. Crime scene investigation is, therefore, the one and only technical resource for evaluating these cases. 相似文献
