Suicide is one of the principal causes of mortality in a prison environment. Although suicide by medication overdose is less frequent than suicide by hanging, self‐strangulation, or vein cutting, it raises questions as to how the medications are obtained, particularly in view of the specific organization of the medication circuit in prisons. We present three cases of suicide by medication overdose involving different therapeutic classes with different distribution circuits and review the regulatory requirements and the measures that could be taken to prevent such suicides.  相似文献

Atherosclerosis is a chronic inflammatory disease creating calcifying plaques in the arterial walls. Because its paleopathological diagnosis remains little studied on skeletal remains, its impact on forensic and archeological data is completely underestimated. Here, 24 skeletal remains from the Milano Cemetery Skeletal Collection have been studied to evaluate the chance of atherosclerotic calcification survival, retrieval, and identification. Through direct comparison with a known autopsy collection and literature, the identification and categorization of several types of calcifications were performed. Clothing elements such as tights or socks played a definitive role in the preservation of the calcifications; hence they are more likely to be found in forensic cases than in archeological ones. Therefore, vascular calcifications are possible to collect and identify in skeletal remains if sufficient care is given to their recovery. Consequently and as markers of the disease, such identification can provide valuable pathological information for forensic and archeological cases.  相似文献

The European Court of Human Rights has been deciding cases concerning LGBT rights since the early 1980s. Its case law on trans rights has changed drastically over time, imposing upon the states of the Council of Europe certain minimum standards regarding the legal recognition of gender identity. In its recent judgment of April 2017 the Court laid down a new rule to be adopted by domestic legislation; namely, that the legal recognition of gender transition cannot be made conditional upon pursuing medical or surgical procedures which have (or are likely to have) sterilising effects. This article analyses the judgment from a critical perspective grounded in queer theory, noting both the positive and the negative elements of the Court's decision.  相似文献

Aftercare services have been suggested to improve reintegration for youth departing residential care programs. The purpose of this study was to collect views from legal professionals about the challenges youth and families face during reintegration and solutions to improve stability. Views were collected from 14 legal professionals (e.g., guardian ad litem, legal counsel) through a survey and 90‐minute nominal group technique focus group. Results indicated parent expectations about re‐entry and lack of services, supports and resources were challenges. Solutions suggested by participants included family, mental health and educational supports, and transition planning. Study limitations and future implications are discussed.  相似文献

Sharp force injuries and drowning are methods exceptionally combined in complex suicides. We report a challenging case of complex suicide by self‐stabbing and drowning that illustrates the difficulty in discriminating between homicide and suicide in such circumstances of death. The corpse of a young man was found submerged in a river, stabbed nine times with two wounds that had penetrated the thorax and had caused lung injuries and a hemopneumothorax. The postmortem and histological examinations were consistent with a death caused by drowning, but the manner of death still remained undetermined. Police investigation finally concluded to a suicide, although no suicide note had been left and the victim had no underlying diagnosed mental disorder. The parameters that may help distinguish suicide from homicide at the autopsy should be interpreted in light of a thorough forensic investigation to determine the exact manner of death in such a case.  相似文献

The ready availability of butane makes butane abuse frequent. Fatalities are rare. This study presents two cases of death by butane overdose. The postmortem analyses were carried out using headspace gas chromatography–mass spectrometry. It revealed femoral blood butane concentrations of 18 and 22 mg/L, respectively, as well as specific combinations of adjuvants in each victim. In one of the victims, brain and fatty tissue also contained butane, pointing to chronic consumption. The originality of this study is to show that the identification of specific combinations of adjuvants can be helpful for identifying the brand of deodorant used. Also, sampling the skin and mucosa can help identify the method of drug delivery. The histological examination documented both the direct toxic effect of the gas on the respiratory mucosa and signs of chronic abuse. Volatile substance intoxications should be systematically considered in case of sudden death in a teenager.  相似文献

Identifying children's risk exposure is the first step toward mortality prevention. This retrospective study determined the causes of child fatalities in Dammam, Saudi Arabia. Death reports of children and adolescents from 1999 to 2015 (= 157) were analyzed. Boys represented most cases (69%) and there were two age peaks (1–5 years and 16–18 years). Accidents (typically immersion) defined the main death circumstance (51%) followed by homicide (25%). Only 33% of cases underwent autopsy, and the most common cause of death was head injury (27%) followed by firearm injury. Only one immersion death underwent autopsy. This study revealed important data about the risk exposure of children in Dammam and emphasizes deficient investigative procedures. Child fatality reviews comprise systematic data collection by multidisciplinary teams to determine the true risks toward children in a community. Such teams do not exist in Arab countries; therefore, strategies should be implemented to initiate them.  相似文献

Stamps and stamp impressions examinations are based on matching defects and design details on the questioned and control samples. These examinations are routinely carried out by document examiners around the world. International proficiency tests for questioned documents examination have been available for decades while similar programs specifically focusing on stamp impressions examination are rare. This study reported a recent proficiency testing program on stamp impressions examination organized by an accredited provider in accordance with ISO/IEC 17043 requirements. Twenty‐four forensic laboratories registered for the program. Apart from giving details on the design and operation of the program, this study also aimed to provide the limitations and difficulties encountered in sample preparations, homogeneity, and stability tests of the testing materials. Various comments and feedbacks received from the participants, particularly in respect of examination approaches, challenges faced by the participants in forming conclusions and their suggestions for further improvement would be evaluated.  相似文献

The skeletal trauma resulting from fatal low (≤3 m) free falls is poorly researched and understood by forensic practitioners. The aim of this study was to identify the types of skeletal trauma resulting from low falls through investigating fracture patterns and morphologies. Skeletal trauma was analyzed using full‐body postmortem computed tomography scans of 145 individuals who died from a low free fall. Trauma was then contextualized to the variables that influence how a person falls using multiple logistic regression. Results showed fracture patterning primarily involved the axial skeleton and that there were a number of patterns significantly associated with the height fallen, pre‐existing health conditions, and age. Analysis of fracture morphologies showed 108 possible fracture types, six of which were significantly associated with the height fallen. Understanding the skeletal trauma characteristic of low free falls will further inform anthropological interpretations of trauma in cases where a fall may be considered the possible mechanism.  相似文献

An approach toward detecting hidden knowledge is the Concealed Information Test (CIT). It relies on the memory of crime‐relevant information. This study investigated whether its validity is susceptible to memory distortion by misleading information. A misleading information paradigm was employed to distort memory prior to an interrogation with a CIT. Forty‐one participants watched a video with specific crime‐related information. After a 1‐week retention interval, misleading information was introduced. Afterward, a CIT was performed, followed by a threefold memory test. When misleading information was presented, memory performance was reduced, and no physiological response differences between crime‐relevant and crime‐irrelevant information were found. Without presenting misleading information, physiological responses differed between responses to crime‐relevant and crime‐irrelevant information. However, responses in all physiological measures also differed between misleading and irrelevant information. The results indicate that the CIT is susceptible to misleading information, which reduces its validity in specific constellations.  相似文献
