The histological study of hair has a long history, dating from the 19th century. We obtained a collection of hair taken from people of known geographic origin. We analyzed these samples according to their transversal cut shape index, derived from computerized image-processing. We noted statistically significant variation according to the geographic origin of subjects. This morphological variation may reflect genetic distance. This reliable, quick, and cheap technique could be used in other existing anthropological material for which DNA analysis is usually difficult. 相似文献

BACKGROUND: The French legislature passed a law in 2005 that assigns a new role to the physician and redefines his liability in end-of-life decisions. METHOD: This law is presented and discussed in context with current French legal practice. RESULTS: This law emphasizes patient autonomy, advocating that the patient be fully informed before treatment, and creates specific procedures to be followed according to whether the patient is conscious or unconscious. In the latter situation, the law reinforces the role of both the patient's surrogate and the patient's advance directives in establishing consent. In these extreme situations, doctors have the option to request a second medical opinion. This joint decision-making procedure is laid down by law and becomes obligatory in the interests of transparency. CONCLUSION: Respect for patients' consent implies the possibility that they may refuse medical care, creating an ethical and legal dilemma of providing medical care or respecting the patients' wishes. The key issue concerning end-of-life patients rests in the decisions taken concerning the continuation or withdrawal of life support and the administration of palliative care. 相似文献

The discovery of an ischaemic myocardial infarction during forensic or scientific autopsy is sometimes surprising when found in a young subject. It is therefore important to find out the etiology of vascular lesions to take preventive measures in the family. In post mortem, some complementary analysis can be performed to determine the diagnosis of ischaemic myocardial infarction and its etiopathogeny. Such analyses, routinely made in forensic practice, are rarely used by pathologists during scientific autopsy. Some biological mediums are stable enough to be used for biological, biochemical and even genetical analyses. We will study the different post mortem analyses, and see their interest and reliability. 相似文献

Comparative radiological identification using bone criteria has mainly been based on cranial characteristics, in particular sinus patterns or bone changes after surgery or trauma. However, the thoracic skeleton, of which antemortem images are frequently available, also provides useful information. We report a case in which ante- and postmortem chest X-rays enabled positive identification of the victim of a road traffic accident. 相似文献

The contribution of magnetic resonance imaging to forensic age estimation of living individuals is a subject of ongoing research. Several studies have focused on the wrist, clavicle, knee, and foot, and shown interesting results regarding the 18-year threshold. Authors have developed various staging systems for epiphyseal growth plate maturation. However, the procedure is observer-dependent and requires experience and a certain time-learning process. To reduce these pitfalls, we have developed an automatic method based on the analysis of variations of gray levels within the epiphyseal–metaphyseal junction. This method was tested on 160 MRI scans of the distal tibial epiphysis in a sample of individuals aged from 8 to 25 years old, after intensity non-uniformity correction of all images. Results showed that in our sample, 97.4 % of males and 93.9 % of females aged 18 years or more would be correctly classified using this method. To our knowledge, automatic methods for MRI analysis have not been used in the field of age estimation yet. Further studies should be performed to assess the validity of this procedure. 相似文献

Characteristics of sharp bone trauma can be extremely useful to determine the origin of cut marks and to provide information regarding the context of death. Using human ribs and clavicle bones, this study analyzes the characteristics of bone kerfs made by different bladed implements, thanks to epifluorescence macroscopy. This technique, which is a nondestructive tool that uses autofluorescence of bones, documents bone damage precisely with high resolution. Both qualitative and quantitative criteria are analyzed. Our results identify unique class characteristics on bone lesions, allowing modeling kerf depending on the weapon, regardless of the type of bone that is wounded. Moreover, we demonstrate for the first time microscopic criteria of directionality, using fluorescence excitation. Orientation of cracks, flakes, and lateral pushing back especially helps in determining the tip and the end of the lesion, leading to the position of the aggressor. Kerf wall characteristics and striation location are also very useful. Epifluorescence macroscopy could be a new tool of choice in anthropology through cut mark analysis in establishing how the blade was used and providing details about the blow. 相似文献

Background
Few studies have looked at lung cancer in prisoners, despite this population is possibly at increased risk of malignancy. In a previous study, we found an early onset of lung cancer in prisoners. Thus, the present CARCAN study was aimed at assessing the epidemiological characteristics, management, prognosis, and incidence of lung cancer in prisoners compared to a sample of non-prisoner patients.Method
We performed a multi-center observational case–control study. Cases were prisoners diagnosed with lung cancer from 2005 to 2013. Controls were non-prisoner lung cancer patients selected from hospital databases and randomly matched to cases (targeted case–control ratio: 1:3). Incidence rates in both groups were calculated using national statistics.Results
Seventy-two cases and 170 controls met inclusion criteria. Cases were mainly men (99%). Mean age at diagnosis was 52.9 (± 11.0) in cases and 64.3 (± 10.1) in controls (p < 0.0001). More case patients were current smokers compared to control patients (83% vs 53%; p < 0.0001). We found no significant differences between the two groups as concerns histologic types, TNM stages at diagnosis, initially-employed treatments, times to management or survival. Incidence rates (2008–2012) in male prisoners were higher than those in the general population in all concerned age groups.Conclusion
There is a shift of lung cancer toward young people in prisons. However, the presentation, management, and prognosis of lung cancer are similar between prisoners and non-prisoners. These finding could justify a specific screening policy for the incarcerated populations.10.
