    Multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) are being increasingly implemented in forensic pathology. These methods may serve as an adjuvant to classic forensic autopsies. Imaging of the interior of corpses is performed using MSCT and/or MRI. MRI, in addition, is also well suited to the examination of surviving victims of assault, especially choking, and helps visualise internal injuries sometimes not seen on external examination of the victim. Various postprocessing techniques can provide strong forensic evidence for use in legal proceedings. The documentation and analysis of postmortem findings with MSCT and MRI and postprocessing techniques (virtopsy) is investigator independent, objective and noninvasive and will lead to qualitative improvements in forensic pathologic investigation. Apart from the accuracy and three dimensionality that conventional documentations lack, these techniques allow for the re-examination of the corpse and the crime scene even decades later, after burial of the corpse and liberation of the crime scene. We believe that this virtual, noninvasive or minimally invasive approach will improve forensic medicine in the near future.

    The disappearance of autopsies is of concern in Neurology for three reasons: in some cases, such as degenerative diseases, the predictive value of clinical diagnosis is still poor; autopsy is, for Neurology, an important piece of the public health watch; the modern post-genomic research needs tissue samples that cannot be obtained by other means for ethical reasons. The main rules of autopsy in France, including the pitfalls of legislation, are recalled. The prerequisites for a renewing of autopsy, the modifications that are required, the procedure to explain its importance in the hospital, among neurologists, and in the society are considered.

  3. TECHNOLOGICAL INNOVATION AND FIRM DEVELOPMENT: THE CASE OF INFOVALLEY DIGITAL AUTOPSY SYSTEM COMMERCIALISATION

    2008-01-01

    Full Text Available Current research emphasises the importance of the successful commercialisation of technology in the development of small firms and the need to address unique contextual dimensions when examining the concept of commercialisation. Guided by product and venture development lifecycle models as well as a structuration perspective, this case study examines how an entrepreneurial venture called Infovalley Life Sciences develops and commercialises the firm's digital human autopsy system despite the fact that the firm operates within an underdeveloped innovation system context. In-depth interviews were conducted with key individuals involved in the innovation and venture development processes. Analysis indicates that the entrepreneur and his or her team co-evolve with their business contexts in creating a favourable nvironment for themselves. This process requires the entrepreneur to integrate his or her broad knowledge of technology applications and the market with his or her team's highly specialised knowledge in the core technology domain; this process results in a successful product launch. This leads to the creation of internal core capability, which supports the commercialisation of new products and thereby contributes to the firm's development and growth. This link between structuration and resource-based perspectives of entrepreneurship augments the conceptualisation of entrepreneurship, technological innovation and firm's development.

    Full Text Available For years, the idea of virtue was unfavorable among researchers and virtues were traditionally considered as culture-specific, relativistic and they were supposed to be associated with social conservatism, religious or moral dogmatism, and scientific irrelevance. Virtue and virtuousness have been recently considered seriously among organizational researchers. The proposed study of this paper examines the relationships between leadership, organizational culture, human resource, structure and processes, care for community and virtuous organization. Structural equation modeling is employed to investigate the effects of each variable on other components. The data used in this study consists of questionnaire responses from employees in Payam e Noor University in Yazd province. A total of 250 questionnaires were sent out and a total of 211 valid responses were received. Our results have revealed that all the five variables have positive and significant impacts on virtuous organization. Among the five variables, organizational culture has the most direct impact (0.80 and human resource has the most total impact (0.844 on virtuous organization.

  7. Was Sir William Crookes epistemically virtuous?

    Science.gov (United States)

    Kidd, Ian James

    2014-12-01

    The aim of this paper is to use Sir William Crookes' researches into psychical phenomena as a sustained case study of the role of epistemic virtues within scientific enquiry. Despite growing interest in virtues in science, there are few integrated historical and philosophical studies, and even fewer studies focussing on controversial or 'fringe' sciences where, one might suppose, certain epistemic virtues (like open-mindedness and tolerance) may be subjected to sterner tests. Using the virtue of epistemic courage as my focus, it emerges that Crookes' psychical researches were indeed epistemically courageous, but that this judgment must be grounded in sensitivity to the motivational complexity and context-sensitivity of the exercise of epistemic virtues. The paper then considers Crookes' remarks on the relationship between epistemic virtuousness and the intellectual integrity and public duties of scientists, thereby placing epistemic virtues in the context of wider debates about the authority of science in late modern societies. I conclude that Crookes' researches into psychical phenomena offer instructive lessons for historians of science and virtue epistemologists concerning the complexity and contextuality of epistemic virtues, and the profitable forms that future studies of virtues in science could take.

    The virtuous doctor has subscribed an oath and by subscribing to this solemn promise, he is committed to live in accordance with the purposes, obligations and virtues established in the medical profession. Cinematic art has shown only a superficial interest in complex aspects of medical profession. An exception is Ingmar Bergman's film "Wild Strawberries", where Professor Isak Borg, a widowed 76-year-old physician, is to be awarded the Doctor Jubilaris degree, 50 years after he received his doctorate at Lund University. During the trip, Isak is forced by a nightmare to reevaluate his professional life as not being a virtuous doctor.

    2011-10-01

    To examine the nature, scope and significance of virtues in the biographies of medical practitioners and to determine what kind of virtues are at play in their ethical behaviour and reflection. A case study involving 19 medical practitioners associated with the Sydney Medical School, using semi-structured narrative interviews. Narrative data were analysed using dialectical empiricism, constant comparison and iterative reformulation of research questions. Participants represented virtuous acts as centrally important in their moral assessments of both themselves and others. Acts appeared to be contextually virtuous, rather than expressions of stable character traits, and virtue was linked to acts that served to protect or enhance fundamental values attached to ontological security and human flourishing. Virtue ethics, in this sense, was the single most important ethical system for each of the participants. Virtue ethics, construed as the appraisal of acts in contexts of risk, danger or threat to foundational values, emerged as the 'natural' ethical approach for medical practitioners in this case study. Teaching medical ethics to students and graduates alike needs to accommodate the priority attached to virtuous acts. © 2011 Blackwell Publishing Ltd.

  12. Designing verbal autopsy studies

    2010-06-01

    Full Text Available Abstract Background Verbal autopsy analyses are widely used for estimating cause-specific mortality rates (CSMR in the vast majority of the world without high-quality medical death registration. Verbal autopsies -- survey interviews with the caretakers of imminent decedents -- stand in for medical examinations or physical autopsies, which are infeasible or culturally prohibited. Methods and Findings We introduce methods, simulations, and interpretations that can improve the design of automated, data-derived estimates of CSMRs, building on a new approach by King and Lu (2008. Our results generate advice for choosing symptom questions and sample sizes that is easier to satisfy than existing practices. For example, most prior effort has been devoted to searching for symptoms with high sensitivity and specificity, which has rarely if ever succeeded with multiple causes of death. In contrast, our approach makes this search irrelevant because it can produce unbiased estimates even with symptoms that have very low sensitivity and specificity. In addition, the new method is optimized for survey questions caretakers can easily answer rather than questions physicians would ask themselves. We also offer an automated method of weeding out biased symptom questions and advice on how to choose the number of causes of death, symptom questions to ask, and observations to collect, among others. Conclusions With the advice offered here, researchers should be able to design verbal autopsy surveys and conduct analyses with greatly reduced statistical biases and research costs.

    Whitaker, Rick

    The world's first commercial fuel cell power plant - the 200-kW PC25™ - works. That is very good news for everyone interested in the market introduction of fuel cell power. Reaching this point has taken years of intensive R&D investment. However, we are finding out now that the investment game in phosphoric acid on-site power is far from over. It has only entered a new phase, where we must invest in creating market volume, to reduce our costs and increase volume. It is in initiating this `Virtuous Cycle' that International Fuel Cells (IFC), through its stationary power subsidiary ONSI, is devoting almost all its time and investment today.

    The word "autopsy" denotes "to see with own eyes." Autopsy (postmortem) is a process that includes a thorough examination of a corpse noting everything related to anatomization, surface wounds, histological and culture studies. Virtopsy is a term extracted from two words "virtual" and "autopsy." It employs imaging methods that are routinely used in clinical medicine such as computed tomography and magnetic resonance imaging in the field of autopsy, to find the reason for death. Virtopsy is a multi-disciplinary technology that combines forensic medicine and pathology, roentgenology, computer graphics, biomechanics, and physics. It is rapidly gaining importance in the field of forensics. This approach has been recently used by forensic odontologists, but yet to make its own mark in the field. This article mainly deals with "virtopsy" where in various articles were web searched, relevant data was selected, extracted, and summarized here.

  18. Congenital hyperthyroidism: autopsy report

    Directory of Open Access Journals (Sweden)

    Lima Marcus Aurelho de

    1999-01-01

    Full Text Available We report the autopsy of a stillborn fetus with congenital hyperthyroidism born to a mother with untreated Graves' disease, whose cause of death was congestive heart failure. The major findings concerned the skull, thyroid, heart, and placenta. The cranial sutures were closed, with overlapping skull bones. The thyroid was increased in volume and had intense blood congestion. Histological examination showed hyperactive follicles. The heart was enlarged and softened, with dilated cavities and hemorrhagic suffusions in the epicardium. The placenta had infarctions that involved at least 20% of its surface, and the vessels of the umbilical cord were fully exposed due to a decrease in Wharton 's jelly. Hyperthyroidism was confirmed by the maternal clinical data, the fetal findings of exophthalmia, craniosynostosis, and goiter with signs of follicular hyperactivity. Craniosynostosis is caused by the anabolic action of thyroid hormones in bone formation during the initial stages of development. The delayed initiation of treatment in the present case contributed to the severity of fetal hyperthyroidism and consequent fetal death.

    Postmortem examinations have been performed for centuries (King and Meehan, Am J Pathol 73(2): 514-541, 1973; Burton, The history of the autopsy. Hodder Arnold, Hachette UK, London, pp 1-10, 2010) and have a long and venerable tradition, one which is sadly on the decline worldwide (Underwood, The future of the autopsy. Hodder Arnold, Hachette UK, London, pp 11-17, 2010; Nemetz et al., Mayo Clin Proc 64:1065-2076, 1989; Kaplan, Hum Pathol 9(2):127-129, 1978; Roberts, N Engl J Med 299:332-337, 1978; Haber, Arch Pathol Lab Med 120:714-717, 1996; AMA Council on Scientific Affairs, Arch Pathol Lab Med 120:721-726, 1996; Sanner, Arch Pathol Lab Med 118:878-883, 1994; Robinson, Hum Pathol 14(7):566-568, 1983). One of the reasons cited for the decline in postmortem examinations is new imaging techniques such as computerized tomography and magnetic resonance imaging. The advent of these new diagnostic procedures has not resulted in obsolescence of the relatively low-cost, high-yield autopsy examination (Goldman et al., N Engl J Med 308:1000-1005, 1983). The procedure for performance of an autopsy, using the Zenker method (Volmar, History of autopsy technique.

    There is increasing recognition of the stress and burnout suffered by critical care workers. Physicians have a responsibility to teach learners the skills required not only to treat patients, but to cope with the demands of a stressful profession. Humor has been neglected as a strategy to help learners develop into virtuous and resilient physicians. Humor can be used to reduce stress, address fears, and to create effective health care teams. However, there are forms of humor which can be hurtful or discriminatory. In order to maximize the benefits of humor and to reduce its harms, we need to teach and model the effective and virtuous use of humor in the intensive care unit.

    Full Text Available Hemophagocytic Syndrome (HPS is frequently fatal condition accompanied with fever, cytopenia, hepatosplenomegaly, abnormal liver function tests, hypertriglyceridemia and hypofibrinogenemia. The goal of this study is to present HPS which we encountered very often in pediatric autopsies and emphasize the necessity of collecting tissue specimens from bone marrow, spleen and lymph nodes by including this syndrome in differentiating autopsy diagnosis from situations with similar symptômes. This case was a four mounth old male child who was autopsied in The State Institute of Forensic Medicine, Istanbul. The child was presented without external trauma findings, small sized subarachnoidal hemorrages in brain, 0.5 cm in diameter atrial septal defect in the heart, and dappled atelectatic feature in both lungs were observed in gross examination. While liver was 380 gr in weight and showed colour changes to yellow, spleen was 320 gr in weight and showed no evidence of gross changing but severe congestion. No evidence of gross pathologic manifestations was found in other organs. The histopathological examination of the organs showed mononuclear inflammatory cell infiltration with histiocytic dominance in myocardium, lungs, brain, cerebellum, lymph nodes and bone marrow. Particularly in bone marrow specimens, there was phagocytosis of erythrocyte, polymorphonuclear leukocyte and lymphocyte in cytoplasm of some histiocytes. The infiltration showed granulomatous structures in brain and cerebellum. In lung specimens, that infiltration was accompanied with alveolitis, alveolar epithelial damage and hyaline membrane materials, but there was no viral inclusion. Liver, kidneys and spleen were not evaluated in detail because of autolysis. In the evidence of clinical and microscopical findings, the diagnosis was 'Hemophagocytic Syndrome'. Hemophagocytic Syndrome which could be secondary to a viral infection was considered the cause of death in this case showed no

  11. Comparison of decomposition rates between autopsied and non-autopsied human remains.

    Bates, Lennon N; Wescott, Daniel J

    2016-04-01

    Penetrating trauma has been cited as a significant factor in the rate of decomposition. Therefore, penetrating trauma may have an effect on estimations of time-since-death in medicolegal investigations and on research examining decomposition rates and processes when autopsied human bodies are used. The goal of this study was to determine if there are differences in the rate of decomposition between autopsied and non-autopsied human remains in the same environment. The purpose is to shed light on how large incisions, such as those from a thorocoabdominal autopsy, effect time-since-death estimations and research on the rate of decomposition that use both autopsied and non-autopsied human remains. In this study, 59 non-autopsied and 24 autopsied bodies were studied. The number of accumulated degree days required to reach each decomposition stage was then compared between autopsied and non-autopsied remains. Additionally, both types of bodies were examined for seasonal differences in decomposition rates. As temperature affects the rate of decomposition, this study also compared the internal body temperatures of autopsied and non-autopsied remains to see if differences between the two may be leading to differential decomposition. For this portion of this study, eight non-autopsied and five autopsied bodies were investigated. Internal temperature was collected once a day for two weeks. The results showed that differences in the decomposition rate between autopsied and non-autopsied remains was not statistically significant, though the average ADD needed to reach each stage of decomposition was slightly lower for autopsied bodies than non-autopsied bodies. There was also no significant difference between autopsied and non-autopsied bodies in the rate of decomposition by season or in internal temperature. Therefore, this study suggests that it is unnecessary to separate autopsied and non-autopsied remains when studying gross stages of human decomposition in Central Texas

    1997-08-01

    This study examined the ability of autopsy to confirm or dispute presumptive cause of death among cardiac surgery patients. Autopsy reports were compared with mortality conference notes that were dictated prospectively before autopsy results were available. Between January 1985 and December 1995, there were 600 hospital deaths among 13,029 adult cardiac surgery patients (4.6% mortality). Of these 600 deaths, 147 (24.5%) had postmortem examination. Annual autopsy rate remained constant over the course of the study. Autopsied patients were younger (60.4 +/- 15 versus 66.7 +/- 13 years [mean +/- standard error of the mean]; p < 0.0001), but their race and sex distributions were similar to deceased patients not having autopsy. Autopsy confirmed clinical presumptive cause of death in 52% (76), disputed clinical diagnosis in 9.5% (14), provided definitive diagnosis in the absence of clinical diagnosis in 13.6% (20), and failed to provide definitive diagnosis in 25% (37). One third of autopsies (39%; 57) provided information that was clinically unrecognized and might have altered therapy and outcome if known premortem. As determined by autopsy, common causes of death were cardiac (27%; 39), unknown (25%; 37), sepsis (14%; 21), stroke (8.8%; 13), cholesterol embolism (4.1%; 6), pulmonary embolism (4.1%; 6), and adult respiratory distress syndrome (4.1%; 6). Autopsy reveals or confirms cause of death in nearly three quarters of cardiac surgical deaths and provides information that differs significantly from premortem clinical impression more than 20% of the time. As such, the autopsy remains important to quality assurance in cardiac surgical care.

    2005-06-01

    The integrity of the human body is an intangible human right acknowledged to persist after death. Violating the integrity of the human corpse is a penal act sanctioned by the 1994 version of the French Penal Code. There are only three exceptions: for science (medical autopsy), for public health (organ removal for graft), and for justice (forensic autopsy). The parents' written agreement is needed to perform a pediatric medical autopsy but not for a forensic autopsy. For the forensic pathologist, taking oath does not imply an authorization to override the precepts of humanity nor the Hippocratic Oath. The forensic pathologist remains subject to civil and penal law. This is why forensic pathologists have an obligation of excellence besides their obligation of means. A pediatric autopsy is a specific procedure compared with an adult autopsy and requires specific training. Forensic pathologists, like all pathologists, who does not have sufficient expertise should not perform pediatric autopsy but rather call in a qualified pediatric pathologist. Tissues or organs removed during a forensic autopsy can be used only for diagnostic purposes, and the parents' agreement must be obtained for any other use.

A third section allows the examiner to report other observations not requested previously, while a final section is also provided for the epicrisis and for the formulation of the final diagnosis, the same as that reported in the first form. The database is coupled with an interactive system for collecting voice comments, thereby replacing the need for tape-recorders in the autopsy room. The user can recall a dictation window, dictate a text, check spelling and insert additional text. The database is also coupled to an image acquisition system, on the assumption that moving images allow a more faithful documentation of reality. Therefore, all rooms in which autopsies are carried out on fetuses or neonates have been equipped with a fixed camera linked to a monitor and a video-recorder. A PCB, used for image digitalization, recognizes up to 16,000,000 different colors. Guided by dedicated software, image files are transferred to a computer and then saved with the autoptic report. The database can be consulted and queried in two principle ways: by key words in the contents or main disease descriptions, or by individual words or phrases contained within the complete text of the reports. The present database system for autopsy reporting has proved itself useful in a pathological anatomy service. The combined presence of images and texts renders the system useful also as a research tool. By linking to a Web site dedicated to pathologic anatomy, it will be possible to display online rare cases involving diagnostic difficulties. The system offers great advantages for present and retrospective diagnostics, as well as for research and education purposes.

    All autopsies (n = 63) performed over the period from January 1, 1989 to December 31, 1990 on patients older than 85 years who died at the Policlinico Umberto I of Rome were reviewed retrospectively. The purpose of the study was to determine the autopsy rate, to ascertain accordance between clinical and pathological diagnoses and to clarify problems in diagnosis and complications of geriatric management in our University Hospital. The autopsy rate was 12.1%. The diagnostic error was particularly high for pulmonary embolism. In 26% of cases both the causes of death and the major clinical diagnoses were confirmed.

  19. From Virtue Ethics to Virtuous Corporation - Putting Virtues into Business Practice

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available This paper aims to contribute to a greater understanding of the theory of virtue ethics in its application in the business arena. In contrast to other ethics approaches, virtue theory emphasises the virtues and moral characters of the individual as moral agent. As such, the theory of virtue ethics provides a useful perspective in making sense of various business ethics issues through placing an emphasis on the moral character of the individuals, and its transformational influences in driving ethical business conduct. Drawing from van Marrewijk's (2003 theory of agency and communion in understanding the corporate sustainability value systems, as well as Moore's (2002, 2005 & 2008 conceptualisation of Alasdair MacIntyre's philosophical approach to ethics, the paper presents a theoretical framework that seeks to explain how individuals, as moral agents, can serve to promote virtuous business conduct and help foster a moral and ethical climate in the organisation as well as society at large.

  20. Is Zaynab Alkali Merely A Feminist Writer? An Appraisal Of The Stillborn And The Virtuous Woman

    Directory of Open Access Journals (Sweden)

    Amase, Emmanuel Lanior

    2014-05-01

    Full Text Available Many African literary critics seem to have some preconceived notions about female writers. Consequently, there has been indiscriminate branding of some female writers either as feminists or female chauvinists. This portrays them as incapable of addressing other topical issues of national interest other than those that affect the women directly. In this paper therefore, we have undertaken an appraisal of Zainab Alkali’s The Stillborn and The Virtuous Woman to buttress our position that the issues in her novels transcend gender imbalance. The paper examines Alkal’s treatment of the clash of westernisation, tradition and city life, political mal-administration, poor infrastructure as well as the challenging environment of the emerging cities. These are issues, which we believe, affect both male and female. The paper advocates a broader look at texts rather than the emphasis on the feminist angle in the interpretation of works by female authors at the expense of probably more important issues.

  2. Robot decisions: on the importance of virtuous judgment in clinical decision making.

    Science.gov (United States)

    2011-10-01

    The aim of this article is to argue for the necessity of emotional professional virtues in the understanding of good clinical practice. This understanding is required for a proper balance of capacities in medical education and further education of physicians. For this reason an ideal physician, incarnating the required virtues, skills and knowledge is compared with a non-emotional robot that is bound to moral rules. This fictive confrontation is meant to clarify why certain demands on the personality of the physician are justified, in addition to a rule- and principle-based moral orientation and biomedical knowledge and skills. Philosophical analysis of thought experiments inspired by science fiction literature by Isaac Asimov. Although prima facie a rule-oriented robot seems more reliable and trustworthy, the complexity of clinical judgment is not met by an encompassing and never contradictory set of rules from which one could logically derive decisions. There are different ways how the robot could still work, but at the cost of the predictability of its behaviour and its moral orientation. In comparison, a virtuous human doctor who is also bound to these rules, although less strictly, will more reliably keep at moral objectives, be understandable, be more flexible in case the rules come to their limits, and will be more predictable in these critical situations. Apart from these advantages of the virtuous human doctor referring to her own person, the most problematic deficit of the robot is its lacking deeper understanding of the inner mental events of patients which makes good contact, good communication and good influence impossible. Although an infallibly rule-oriented robot seems more reliable at first view, in situations that require complex decisions like clinical practice the agency of a moral human person is more trustworthy. Furthermore, the understanding of the patient's emotions must remain insufficient for a non-emotional, non-human being. Because

  3. Keeping cool, staying virtuous: Social media and the composite habitus of young Muslim women in Copenhagen

    2015-05-01

    Full Text Available This article builds on long-term anthropological fieldwork among young Muslim women in a social housing area in Copenhagen. It explores how morality, modesty, and gender- and generational relations become reconfigured in the ways in which young women use the Smartphone and social media to navigate their everyday lives. I focus on love and marriage, the imperatives of appearing cool among peers, and keeping the family’s honour intact through the display of virtuous behaviour. Building on Bourdieu’s writings on the split habitus, I introduce the term composite habitus, as it underscores the aspect of a habitus that is split between (sometimes contradictory composite parts. The composite habitus of the young women is more than a hysteresis effect (where disposition and field are in mismatch and the habitus misfires, as the composite habitus also opens up to a range of possible strategies. I present examples of how intimate and secret uses of Smartphones have played out and show how social media have allowed for multiple versions of the self through managing public and secret relationships locally and across long distances.

  4. For a healthier future: a virtuous cycle for reducing exposure to persistent organic pollutants

    2017-01-01

    In the modern society, people are exposed to various pollutants during their lifetime. Worldwide, the status of children's health has changed in recent decades. Some studies have attempted to identify the causes of these changes and whether they relate to pollutant exposure; however, such attempts have faced major challenges because human life is complex, involving many social and environmental factors. Several long-term cohort studies are being conducted to determine the relationship between diseases and social and environmental factors in children. Even before we establish complete proof of adverse effects, we should attempt to decrease risk to future generations by adopting precautionary principles. Environmental exposure to persistent organic pollutants can be reduced throughout the stages of life—the fetal period, newborn and infant periods, childhood, adolescence and adulthood (preconception) by individuals as well as by society as a whole. Through reducing environmental exposure to pollutants, adverse health effects can also be reduced, which will contribute to healthier future generations. Here, we suggest a virtuous cycle for improving the health of future generations through reduced exposure to persistent pollutants. PMID:28515209

  5. Evidence-based interventions for reading and language difficulties: creating a virtuous circle.

    2011-03-01

    BACKGROUND. Children may experience two very different forms of reading problem: decoding difficulties (dyslexia) and reading comprehension difficulties. Decoding difficulties appear to be caused by problems with phonological (speech sound) processing. Reading comprehension difficulties in contrast appear to be caused by problems with 'higher level' language difficulties including problems with semantics (including deficient knowledge of word meanings) and grammar (knowledge of morphology and syntax). AIMS. We review evidence concerning the nature, causes of, and treatments for children's reading difficulties. We argue that any well-founded educational intervention must be based on a sound theory of the causes of a particular form of learning difficulty, which in turn must be based on an understanding of how a given skill is learned by typically developing children. Such theoretically motivated interventions should in turn be evaluated in randomized controlled trials (RCTs) to establish whether they are effective, and for whom. RESULTS. There is now considerable evidence showing that phonologically based interventions are effective in ameliorating children's word level decoding difficulties, and a smaller evidence base showing that reading and oral language (OL) comprehension difficulties can be ameliorated by suitable interventions to boost vocabulary and broader OL skills. CONCLUSIONS. The process of developing theories about the origins of children's educational difficulties and evaluating theoretically motivated treatments in RCTs, produces a 'virtuous circle' whereby theory informs practice, and the evaluation of effective interventions in turn feeds back to inform and refine theories about the nature and causes of children's reading and language difficulties.

  10. EDWARDS SYNDROME: AUTOPSY REPORT OF TWO CASES

    Directory of Open Access Journals (Sweden)

    Arpitha Chinnarappa

    2016-03-01

    Full Text Available BACKGROUND The Trisomy 18 syndrome (Edwards syndrome is an autosomal disorder due to the presence of an extra chromosome on chromosome 18. It is a rare genetic disorder involving multiple organ systems. The recognizable features of syndrome include prenatal and postnatal growth retardation, characteristic craniofacial features, distinctive hand posture, short sternum and major malformations of heart & kidney. Ultrasound is useful in the early antenatal detection and helps to minimize the trauma related to the termination of pregnancy at advanced gestation. Autopsy is useful in finding new anomalies and confirming antenatal ultrasonographic findings. Here we illustrate two case reports with phenotypic features, autopsy findings and brief review of literature. Genetic counselling regarding the risk of recurrence in future pregnancies is essential.

  11. Can postmortem fetal MR imaging replace autopsy?

    2001-02-01

    The purposes of this study were to compare postmortem fetal MRI findings with autopsy findings and to assess whether postmortem MRI can replace autopsy. The study group consisted of 13 stillborn fetuses, seven that died immediately after birth, and five terminated because of anomalies seen on prenatal sonograms. A total 17 were male, and eight were female, and their gestational ages were from 20 to 41 (average;28.2) weeks. Spin-echo T1-and T2-weighted axial, sagittal, and coronal MR images were obtained, and autopsy findings were divided into major and minor. A major finding was defined as an anomaly or syndrome which caused fetal death or termination of the pregnancy: minor findings were classified, on the basis of gross inspection, as internal or external. MR images were retrospectively analyzed by two radiologists unaware of the autopsy findings, and by comparison with these, the postmortem MRI detection rates for major and minor findings was then determined. In seven of 25 fetuses, MR imaging revealed major findings, a dietction rate of 100%. There were two cases of anencephaly, two of trisomy-18, and one each of hydrops fetalis with large cystic hygroma, diaphragmatic hernia, and Dandy-Walker malformation. Twenty-three of 60 minor findings (38.3%) were detected by MRI. The detection rates for external and internal findings were 29.6%(8/27) and 45.5%(15/33), respectively. Although a limitation of our study is the low detection rate for minor findings, postmortem fetal MRI may help diagnose the major cause of fetal death.

    2014-06-01

    We reviewed our Children's Hospital autopsies (1986-2009, 3-8 year groups) to determine the contribution of infections/inflammation to death and trends over time. Infections were categorized as (1) underlying cause of death, (2) mechanism of death complicating another underlying cause of death, (3) contributing (4) agonal or (5) incidental. Of 608 autopsies (44% of deaths), 401 had 691 infections (66%, 1.72 infections/infected child). In categories 1-5, there were 85 (12.3%), 237(34.3%), 231 (33.4%), 82 (11.9%) and 56(8.1%) infections. Leading infections include bronchopneumonia (188), sepsis (144- Enterococcus most common with 22), meningitis (35- Streptococcus pneumoniae most common with 10), pneumonitis (33), peritonitis (29). Sepsis declined in 2002-2009, attributed to fluid resuscitation standardization. Meningitis declined after 1993, and may be partially attributed to vaccines (Hemophilus influenza, Streptococcus pneumoniae). Despite advances in anti-microbial therapy, 66% of pediatric autopsies had inflammatory lesions, predominately as the mechanism or contributing factor rather than the underlying cause of death.

    We studied two autopsy cases of primary pituitary carcinoma. Case-1. A 45 year old female was admitted on Oct. 4 1978, with a complaint of right homonymous hemianopsia. And diagnosis was pituitary adenoma. Partial removal of pituitary tumor was performed on Oct. 23 1978. She died on Dec. 5 1978 due to bleeding of gastrointestinal tract. Autopsy disclosed a pituitary carcinoma invading the left hypothalamus, mamillary body, optic and V cranial nerves, and mid brain as well as sphenoid bone. No extracranial metastasis was noted. Case-2. A 44 year old female with a history of acromegaly for 6 years was admitted with a complaint of headache on May 8 1976. She was diagnosed as having pituitary adenoma. The subtotal removal of pituitary tumor was performed on May 21 1976 and followed by 4500 rad irradiation. At this time, pathological diagnosis was eosinophilic adenoma. Seven years later, she complained of progressive right hearing disturbance, dysarthria and ataxic gait 1983. The second subtotal removal of pituitary tumor was performed with a diagnosis of recurrence of pituitary adenoma on Oct. 7 1983. After the operation, she complicated sepsis and died on Jan. 14 1984. An autopsy disclosed a pituitary carcinoma from residual pituitary gland, continuously extending to the subarachnoid space of the pons, and invading right cerebello-pontine angle and cerebellum. The histological examination revealed pituitary carcinoma with high pleomorphism and glioblastoma multiform-like feature were within the tumor.(ABSTRACT TRUNCATED AT 250 WORDS)

    Semsarian, Christopher; Ingles, Jodie

    2016-10-01

    Sudden cardiac death (SCD) is a rare but devastating complication of a number of underlying cardiovascular diseases. While coronary artery disease and acute myocardial infarction are the most common causes of SCD in older populations, inherited cardiac disorders comprise a substantial proportion of SCD cases aged less than 40 years. Inherited cardiac disorders include primary inherited arrhythmogenic disorders such as familial long QT syndrome (LQTS), Brugada syndrome (BrS), catecholaminergic polymorphic ventricular tachycardia (CPVT), and inherited cardiomyopathies, most commonly hypertrophic cardiomyopathy (HCM). In up to 40% of young SCD victims (defined as 1-40 years old, excluding sudden unexplained death in infancy from 0 to 1 years, referred to as SIDS), no cause of death is identified at postmortem [so-called "autopsy negative" or "sudden arrhythmic death syndrome" (SADS)]. Management of families following a SCD includes the identification of the cause of death, based either on premorbid clinical details or the pathological findings at the postmortem. When no cause of death is identified, genetic testing of DNA extracted from postmortem tissue (the molecular autopsy) may identify a cause of death in up to 30% of SADS cases. Targeted clinical testing in a specialized multidisciplinary clinic in surviving family members combined with the results from genetic testing, provide the optimal setting for the identification of relatives who may be at risk of having the same inherited heart disease and are therefore also predisposed to an increased risk of SCD.

    Verbal autopsy (VA) is a standardized method for investigating causes of death. Currently, the Mexican Ministry of Health uses officially VA to reconstruct the history of women who died of cervical cancer. to describe the findings of the VA of dead women due to cervical cancer in Tijuana, Baja California, Mexico. All death certificates issued in the years 2001 and 2001 in which cervical cancer was the main cause of death were reviewed. The VA included forty-five questions exploring six domains: subjects' personal information, sociodemographic characteristics, history of the disease, timely medical care, risk factors, affiliation to social security, and information registered in the death certificate. Seventy-nine women out of 97 had VA. The mean age was 54 years; 33% completed elementary school; 32% had smoking history; 50% had more than five pregnancies; 42% started sexual activity before the age of 17, 52% had had 2 to 3 sexual partners. 60% had Papanicolau test; 90% knew about their condition; 86% received medical care and 34% knew they had cancer one year before death. Verbal autopsy revealed that 40% of women who died of cervical cancer did not have Papanicolau test before being diagnosed.

    Over the past 30 years, the perinatal mortality rate (PMR) in Australia has been reduced to almost a quarter of that observed in the 1970s. To a large extent, this decline in the PMR has been driven by a reduction in neonatal mortality. Stillbirth rates have, however, remained relatively unchanged, and stillbirth rates for Aboriginal or Torres Strait Islander mothers have remained approximately twice that for non-Indigenous women over the last 10 years. The causes for this difference remain to be fully established. Fetal autopsy is the single most important investigative tool to determine the cause of fetal demise. While facilitators and barriers to gaining consent for autopsy have been identified in a non-Indigenous context, these are yet to be established for Indigenous families. In order to address the gap in stillbirths between Indigenous and non-Indigenous mothers, it is essential to identify culturally appropriate ways when approaching Aboriginal and Torres Strait Islander families for consent after fetal death. Culturally safe and appropriate counselling at this time provides the basis for respectful care to families while offering an opportunity to gain knowledge to reduce the PMR. Identifying the cause of preventable stillbirth is an important step in narrowing the disparity in stillbirth rates between Indigenous and non-Indigenous mothers. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

  19. Performance of the local health system and contingent influences in Northeast-Brazil: breaking vicious and virtuous circles

    Directory of Open Access Journals (Sweden)

    Regianne Leila Rolim Medeiros

    2013-11-01

    Full Text Available Organizational theory has long emphasized the importance of contingent, environmental influences on organizational performance. Similarly, research has demonstrated the importance of local political culture and informal management on the performance of the local health system, establishing vicious and virtuous circles of influence that contribute to increasing inequalities in performance among decentralized local health systems. A longitudinal ethnography studied the relationship between these elements in the same rural municipality in Northeast Brazil after a four-year interval. The second study found the local health system performance much improved. Two main factors appear to have interacted to bring this about: leadership vision and power to implement of one individual; professionalization of the local health system by hiring a significant number of senior health staff. The origins of these influences combine initiatives at local, state and federal levels.

  20. Are virtuous people happy all around the world? Civic virtue, antisocial punishment, and subjective well-being across cultures.

    2013-07-01

    Psychological research postulates a positive relationship between virtue and happiness. This article investigates whether this relationship holds in cultures where virtue is not socially appreciated. We specifically focus on civic virtue, which is conceptualized as citizens' honesty in interactions with state institutions (e.g., tax compliance). Two indicators served as measures of the degree to which civic virtue is a part of a country's normative climate: These were each country's mean level of punishment directed at above-average cooperative players in public good experiments and the extent to which citizens justify fraud and free-riding. The results of two studies with data from 13 and 73 countries demonstrate that a positive relationship between civic virtue and happiness/life satisfaction is not universal: In countries where antisocial punishment is common and the level of justification of dishonest behaviors is high, virtuous individuals are no longer happier and more satisfied with life than selfish individuals.

  1. In Defense of Clinical Autopsy and Its Practice in Cuba.

    2017-01-01

    There has been a notable decrease in the global practice of clinical autopsy; the rate has fallen to below 10%, even in high-income countries. This is attributed to several causes, including increased costs, overreliance on modern diagnostic techniques, cultural and religious factors, the emergence of new infectious diseases and negative attitudes on the part of doctors, even pathologists. Alternative methods to autopsy in postmortem studies have been developed based on imaging, endoscopy and biopsy (all quite expensive). These methods have been used in developed countries but never as effectively as the classic autopsy for identifying cause of death and potential medical errors. Although Cuba has also seen a decrease in its autopsy rates, they remain comparatively high. Between 1996 and 2015, there were 687,689 hospital deaths in Cuba and 381,193 autopsies, 55.4% of the total. These autopsies have positively affected medical care, training, research, innovation, management and society as a whole. Autopsies are an important tool in the National Health System's quest for safe, quality patient care based on the lessons learned from studying the deceased.

    2016-09-01

    Any autopsy has safety and risk management issues, which can arise in the preautopsy, autopsy, and postautopsy phases. The London Health Sciences Department of Pathology and Laboratory Medicine Autopsy Checklist was developed to address these issues. The current study assessed 1 measure of autopsy safety: the effectiveness of the checklist in documenting pathologists' communication of the actual or potential risk of blood-borne infections to support staff. Autopsy checklists for cases done in 2012 and 2013 were reviewed. The frequency of communication, as recorded in checklists, by pathologists to staff of previously diagnosed blood-borne infections (hepatitis B/C and human immunodeficiency virus) or the risk of infection based on lifestyle (eg, intravenous drug abuse) was tabulated. These data were compared with medical histories of the deceased and circumstances of their deaths described in the final autopsy reports. Information about blood-borne infections was recorded less frequently in the checklists compared with the final reports. Of 4 known human immunodeficiency virus cases, there was no checklist documentation in 3. All 11 hand injuries were documented. None of these cases had known infectious risks. The Autopsy Checklist is a standardized means of documenting safety and risk issues arising during the autopsy process, but its effectiveness relies on accurate completion.

    2011-11-01

    Autopsy rates have declined throughout the world although autopsy serves as an important tool in quality management. Working together with the Department of Heart Surgery of the Heart Centre in Leipzig clinical and autopsy diagnoses were compared. Between 2000 and 2003 an autopsy was performed in 468 patients. Data from clinical and postmortem examinations were prospectively analysed regarding causes of death, concomitant diseases and postoperative complications. Discrepancies between clinical and postmortem cause of death were identified in 23.1% of these patients. In 99.1% of the patients concomitant diseases (e.g. myocardial hypertrophy, pulmonary embolism, former stroke) could be identified, 57.6% were unknown pre-mortem and 19.2% were considered to be of relevance for surgical therapy. Autopsy is the final and most comprehensive physical examination. Autopsy is also the basis of training for pathologists in interpreting interrelated diagnoses. Therefore the task of pathologists is to enhance the appreciation of autopsy among clinical colleagues by working closely side by side. By communication an autopsy can deliver an effective achievement in terms of being relevant for praxis.

    A 61-year-old man with a sensation of chest compression was admitted to our hospital. He had hemothorax. After drainage with a chest tube, chest CT scan revealed multiple bilateral pulmonary nodules with slight pleural thickening. Open pleural biopsy was performed and the biopsy specimens showed tumor cells with sarcomatoid proliferation, but no definite epithelial pattern. Initial immunohistochemical staining was negative for keratin and carletinin, but positive for desmin, suggesting rhabdomyosarcoma. After supportive care, he died due to progression of the disease. Autopsy revealed extensive invasion suggesting mesothelioma, so the immunohistochemical staining was repeated. Because it revealed patchy staining for keratin and carletinin, this case was diagnosed as sarcomatoid mesothelioma. Differential diagnosis of sarcomatoid mesothelioma or rhabdomyosarcoma is made by immunohistochemical staining, but it is sometimes difficult. For the selection of the best treatment strategy for mesothelioma especially in the early stage, we should be aware of this difficulty.

    A 38-year-old male slipped accidentally and fell from a height of 4.6 m, and was admitted to a hospital. A radiograph indicated a linear fracture of the parietal bone across the sagittal sutura, and a computed tomography scan of the head showed severe subdural hematoma on both parietal sides, so an operation was performed to remove the hematoma. Five hours after the operation, brain death due to a cerebral herniation occurred, and he died six days later. Autopsy revealed a linear fracture of the parietal bones, which crossed obliquely the sagittal sutura. A slightly lacerated wound of the dura mater was seen on the sagittal sutura, from where the latter half of that point to the left and right transverse sinuses were occluded completely with thrombosis. The brain was markedly swollen. From these findings, the victim was considered to have died from acute cerebral swelling due to traumatic thrombosis of the superior sagittal sinus.

    Traditionally, verbal autopsies (VA) are collected on paper-based questionnaires and reviewed by physicians for cause of death assignment, it is resource intensive and time consuming. The Population Health Metrics Research Consortium VA questionnaires was made available on an Android-based application and cause of death was derived using the Tariff method. Over one year, all adult deaths occurring in 48 villages in 4 counties were identified and a VA interview was conducted using the smartphone VA application. A total of 507 adult deaths were recorded and VA interviews were conducted. Cardiovascular disease was the leading cause of death (35.3%) followed by injury (14.6%) and neoplasms (13.5%). The total cost of the pilot study was USD28 835 (USD0.42 per capita). The interviewers found use of smartphones to conduct interviews to be easier. The study showed that using a smartphone application for VA interviews was feasible for implementation in rural China.

    BAEPs were recorded in a 70-year-old man who had developed symptoms indicative of Wallenberg syndrome. He died, of extracerebral causes, shortly after hospitalization and an autopsy study was done on the brainstem lesions. Right ear stimulation disclosed BAEP abnormalities, but gave no indication of the level of the ischemic disorder. Histopathological examination showed a typical right dorsolateral medullary infarct. A detailed study of the acoustic pathways demonstrated their anatomical integrity. These findings confirm the uncertainty that still exists as to the exact location and type of generators of BAEP components. They suggest, moreover, that BAEPs can give objective evidence of functional impairment of brainstem acoustic structures even in the absence of persistent anatomical damage.

    The autopsy is an integral part of the service of a large academic pathology department. Timely reporting is central to providing good service and is beneficial for many stakeholders, including the families, the clinical team, the hospital, and the wider community. The current study aimed to improve hospital-consented autopsy reporting times (turnaround time, TAT) by using lean principles modified for a healthcare setting, with an aim of signing out 90% of autopsies in 90 days. An audit of current and historical TATs was performed, and a working group incorporating administrative, technical, and professional staff constructed a value stream map documenting the steps involved in constructing an autopsy report. Two areas of delay were noted: examination of the microscopy and time taken to sign-out the report after the weekly autopsy conference. Several measures were implemented to address these delays, including visual tracking using a whiteboard and individualized tracking sheets, weekly whiteboard huddles, and timelier scheduling of clinicopathologic conference rounds. All measures resulted in an improvement of TATs. In the 30 months prior to the institution of lean, 37% of autopsies (53/144) were signed out in 90 days, with a wide variation in reporting times. In the 30 months following the institution of lean, this improved to 74% (136/185) ( P lean; 63 days post-lean). The application of lean principles to autopsy sign-out workflow can significantly improve TATs and reduce variability, without changing staffing levels or significantly altering scheduling structure.

    Full Text Available Ethical education in Aristotle is analyzed and the formation of the virtuous character as a key factor in the achievement of happiness is emphasized. The happy life is based on virtue which, in turn, is based on education and not on any other forms of life. The formation on the activity of the soul is not enough to achieve a happy life. Rational virtue differentiates the good man from the others. It manifests itself in good acts expressed through balanced attitudes and contemplation. Ethical education is the basic criterion for character formation. The constant practice of virtuous deeds makes the human being achieve discernment to do what is appropriate and thus achieve virtue and happiness.

    In France, families of the deceased raised concerns as regards to the conditions of restoration of body. If scientists hospital autopsies are organized by the Bioethics Law of August 6, 2004, the forensic autopsies were so far not provided with such a legal framework. The legislator has proposed the creation of a new chapter in the Code of Criminal Procedure institutionalizing forensic activities. This legislative evolution allows the harmonization of practices; forensic pathologists must be involved in these changes by bringing their scientific expertise, notably through improving their autopsy techniques.

    The transmission of infectious and neoplastic diseases is a potential risk of tissue allografting. In this study, we analyzed the occurrence of occult disease in tissue donors as detected by standard screening and autopsy. Whereas 18% of the potential donors initially evaluated were eliminated on the basis of their medical and social histories, laboratory screening and autopsy revealed that an additional 9% of tissue donors had undetected, transmissible disease that prohibited tissue donation. This report emphasizes once again the risk of occult disease being transplanted with grafts and the need for autopsy to reduce the likelihood of this occurring. If donor selection, appropriate screening tests, and autopsy are carefully carried out, the risk of transmitting diseases from tissue allografts can be kept to a minimum.

    Autopsy, or post-mortem examination, is the dissection of a dead body. It is performed for many reasons. Attitudes toward dead bodies vary with religious beliefs and cultural and geographical backgrounds. We have carried out an extensive literature review to determine the Islamic view and current practice of Autopsy, in at least four Arab countries which published their experiences. Several research articles have studied the history of Islamic Autopsy as well as the current situation and legal debates about it. The overwhelming conclusion is that data is lacking. More must be published from Arabic Muslim countries and more research done to correct misconceptions. We also recommend more application of non-invasive Autopsy.

    Full Text Available Background: An audit of autopsies of maternal deaths is important for the establishment of accurate cause of maternal deaths and to determine the contribution of various etiologies responsible in a given community. Aim: To study the causes of maternal deaths as determined by a pathological autopsy. Settings and Design: A retrospective study of all the cases of maternal deaths that underwent a pathological autopsy in a tertiary healthcare center from January 1998 to December 2006. Materials and Methods: The autopsy records with clinical notes were retrieved; gross and histopathology specimens and slides were studied to establish the accurate cause of maternal deaths. The variables like age (years, stay in the hospital, gravidity, trimester of pregnancy and method of delivery were used to classify and analyze the data from the autopsies. The causes of maternal deaths were divided in to direct and indirect; each being classified into subgroups based on the most evident pathology on autopsy. Results: The Maternal Mortality Rate (MMR over a nine-year period (1998-2006 was 827/100000 live births (471 maternal deaths against 56944 live births. An autopsy was performed in 277 cases (58.8%. In the autopsy group, the most common causes of maternal mortality were pre-ecclampsia/ecclampsia (40 of 277, 14.44% and hemorrhage (32 of 277; 11.55%; However, indirect causes like infectious diseases (27 of 277; 9.75% and cardiac (27 of 277; 9.75% disease also contributed to maternal deaths. Conclusion: Indirect causes like rheumatic heart disease and infections like tuberculosis, malaria or leptospirosis and nutritional anemia are still major causes of maternal mortality in developing countries like India. Intensive efforts need to be taken in these areas to reduce the maternal mortality in developing countries like India.

    Full Text Available Sirenomelia also known as mermaid syndrome, characterized by fused lower limbs, is a lethal and rare congenital abnormality. This is an extreme example of caudal regression syndrome caused by vascular steal of single umbilical artery. Sirenomelia is found approximately one in 100,000 live births and is usually fatal because of complications associated with pulmonary hypoplasia, abnormal development of the kidneys and urinary bladder. Most of the cases are associated with maternal diabetes and single umbilical artery. We report a case of sirenomelia terminated at 21weeks of gestation due to multiple congenital abnormalities. Antenatal scan of a25-year old primi revealed a single live fetus of 21 weeks gestation with severe olighydramnios, non-visualization of kidneys and bladder and lower part of the spine. This pregnancy was terminated and the specimen sent to the department of anatomy for fetal autopsy. On external examination,a tail like rudimentary single midline lower limb without foot was noted. There were no external genitalia and anal orifice. Internal examination revealed hypoplastic lungs, atrial septal and ventricular septal defects, aberrant right subclavian artery, hypoplastic abdominal aorta distal to the single umbilical artery, complete agenesis of urinary system, rectal agenesis and rudimentary indeterminate gonads. We would like to discuss the clinical features, etio- pathogenesis and review of literature of sirenomelia. Early diagnosis and termination of this lethal congenital anomaly results in minimizing the trauma related to the termination of pregnancy at advanced gestation.

    A manner of death may be ruled undetermined by the forensic pathologist when there is insufficient information about the circumstances surrounding the death to make a ruling. The aim of our study was to retrospectively analyze a series of autopsy cases that were classified as undetermined manner of death after complete investigations. In all, 48 cases were examined. In 23 cases (48%), the cause of death was determined. The most frequent cause of death was toxic death (n = 11). More than one manner of death was deemed conceivable for most cases (n = 39). The most frequent and the most probable manner of death was accident (n = 37). Homicide was not excluded in about 23% of the cases. Our study showed that the manner of death may remain undetermined despite an established cause of death, and even when two or more conceivable causes of death are considered. Our study pointed out that undetermined manner of death covers a wide range of situations and that homicide may be underestimated. © 2015 American Academy of Forensic Sciences.

    Full Text Available INTRODUCTION: Perinatal death rate is declining in developed and developing countries and so are perinatal autopsies. In the present days due to wider availability and awareness of prenatal scanning more and more congenital malformations are picked up in e arlier weeks of gestation. This helps in counselling of the couple which usually leads to an informed decision on medical termination of pregnancy. Autopsy performed on such fetuses , yields additional information in many cases. AIMS: The study was carried out to determine how well the prenatal ultrasound findings correlate with autopsy findings and also to determine the cause of death where ultrasound was not performed in patients who had spontaneous intrauterine death and abortion. MATERIALS AND METHODS: T his was a prospective study carried out over a period of two years in the department of pathology at Kamineni Academy of Medical Sciences and Research Centre , Hyderabad , from January 2013 to December 2014. A total of 23 fetal autopsies were performed of wh ich one was a twin pregnancy. Brief maternal history , prenatal ultrasound scans , relevant biochemical markers and genetic studies wherever done , were noted. RESULTS : There were 14 male (60.86% and 8 female (34.78% fetuses , and in one case (4.34% gender could not be identified. Nineteen cases (82.60 % were less than 28 weeks of gestation. Medical termination of pregnancy was done in 13 cases (56.52 % whereas , 10 patients (43.47 % had spontaneous intrauterine death of the fetus. Ultrasound scanning was done in 15 cases (65.21 %. In 13 cases (86.66 % the ultrasound and autopsy findings were correlating whereas in two cases (13.33 % there were findings on imaging study which could not be identified on autopsy. Ultrasound was not done in 8 cases (34.78 % out of which 5 cases (62.5 % showed findings on autopsy which could have led to the fetal demise. Twelve cases (52.17 % were referral cases which had come from other hospitals

  18. The influence of Plato, Aristotle, and the ancient Polis on a programme for congenital cardiac surgery: the virtuous partnership.

    The problems that exist in maintaining a partnership in paediatric cardiac surgery are considerable. They relate to fairness in allocation of time for leisure, the apportioning of cases between the partners, internal competition between them, financial considerations, and promotion of the ego. In this review, we discuss our own experiences in maintaining a partnership over a period of more than 18 years, relating such a "virtuous partnership" to the writings of Plato and Aristotle, and setting it against the tenets of the ancient Greek polis. The polis, or city state, came to prominence in ancient Greece during the golden age of Pericles, this period seeing the initial evolution of Western philosophy, as well as numerous other scientific, artistic and architectural advances. The concept of the polis was to create a natural association with its citizens that nurtured all that is best in people, at the same time defining their character. In this respect, according to Plato, the person and the polis are mirror images. Aristotle then expanded this notion to incorporate the various forms of friendship, which he pointed out last only as long as the interrelated pleasure survives. Using these principles as the point of departure, we argue that cardiac surgeons should respect moral virtue in each other. Extending this process means that we should also respect, and celebrate, our relationships with affiliated physicians, nurses, perfusionists, administrators, and all concerned in the care of children with congenitally malformed hearts. In this way, we create a virtuous partnership for congenital cardiac surgery that promotes all that was good, as engendered in the ancient Greek polis. As we extend these observations to the modern world, we discuss some of the features that have permitted us to work so well together. One of the most important is a summoning and unwritten tenet that greets us as we enter the operating room, namely "check your ego at the door". The operative

    Agenesis of the corpus callosum is currently diagnosed prenatally with ultrasound and MRI. While the diagnostic aspects of callosal defects are widely addressed, anatomo-histological data from fetal autopsies are sparse. Callosal defects were present in 50 fetal autopsies. Four distinct groups of complete, partial, hypoplastic, and mixed defects were determined by the gross and histologic details of the corpus callosum. These details helped to rule out other midline defects such as holoprosencephaly. Additional autopsy findings enabled specific diagnoses and suggested etiopathogeneses. Hypoplastic and mixed defects were associated with more abnormalities of the cerebral hemispheres and internal organs. The four groups did not differ according to gender, external dysmorphism, or cerebellar and brainstem anomalies. Defects were classified as syndromic (68 %), encephaloclastic (8 %), undetermined (14 %), or isolated (10 %) based on the autopsy findings. Isolated agenesis of the corpus callosum was diagnosed in only 10 % of the cases in this series, compared to higher numbers diagnosed by prenatal ultrasonography and MRI. Therefore, the autopsy, through its detailed, careful evaluation of external, as well as gross and histological internal features, can elucidate the etiopathogenesis of agenesis of the corpus callosum and suggest specific diagnoses which cannot be ascertained by prenatal imaging.

    Since 1972 organ transplantations of kidney, bone marrow, liver, heart and lung have been performed at the University Hospital of Essen, Germany. Out of 2535 transplantations until September 1993, autopsies were performed in 157 patients In 25 patients (15.9%) neuropathologic findings (n = 26) were found. In 97 autopsies after bone marrow transplantation, 9 patients (9.3%) exhibited a severe neuropathologic alteration. In six patients (6/9; 66.6%), necrotisizing toxoplasmose encephalitis was found. Other cases showed a septic-metastatic mycotic encephalitis with crypto-coccus neoformans and candida albicans (n = 2) and leucemia infiltrates (n = 1). Massive cerebral hemorrhage was the most frequent neuropathologic finding after liver (4/8) and kidney transplantation (3/6). In addition liver-transplanted patients exhibited septic-metastatic encephalitis (3/8) and embolic brain infarct (1/8) as well as cerebral metastases (2/6) and primary malignant cerebral lymphoma in kidney transplantation (1/6). CNS findings in five autopsies after heart-lung-transplantation were diverse. They comprised intracerebral hemorrhage, intravasal lymphoma and septic-metastatic encephalitis, respectively. In summary, neuropathologic autopsy findings after organ transplantation are diverse and preferentially comprise infections, cerebral hemorrhages, and malignant lymphomas. After bone marrow transplantation, the most frequent neuropathologic autopsy finding was toxoplasmose encephalitis and massive cerebral hemorrhages after liver and kidney transplantations.

    2016-01-01

    Full Text Available Meckel-Gruber syndrome (MGS is a rare lethal congenital malformation affecting 1 in 13,250-140,000 live births. The classical diagnostic triad comprises multicystic dysplastic kidneys, occipital encephalocele, and postaxial polydactyly. It can variably be associated with other malformations such as cleft lip and palate, pulmonary hypoplasia, hepatic fibrosis, and anomalies of central nervous system. A 20 weeks fetus was diagnosed as MGS with classical features along with many other congenital abnormalities such as microcephaly, microphthalmia, hypertelorism, cleft lip and palate, neonatal teeth, and the right side club foot which were detected only after doing autopsy. This case is reported because of its rarity emphasizing the importance of neonatal autopsy in every case of fetal death, especially where the antenatal diagnosis has not been made previously. A systematic approach to accurate diagnosis of MGS based on autopsy will be described here which can allow recurrence risk counseling and proper management in future pregnancies.

    Full Text Available Abstract Objectives The aim of the study was to determine if differences in clinical diagnosis versus autopsy findings concerning the cause of death in polytrauma fatalities would be detected in 19 cases of fatal polytrauma from a Level 1 trauma centre. Methods Clinical diagnoses determining the cause of death in 19 cases of fatal polytrauma (2007 - 2008 from a Level 1 trauma centre were correlated with autopsy findings. Results In 13 cases (68%, the clinical cause of death and the cause of death as determined by autopsy were congruent. Marginal differences occurred in three (16% patients while obvious differences in interpreting the cause of death were found in another three (16% cases. Five fatalities (three with obvious differences and two with marginal differences were remarked as early death (1-4 h after trauma and one fatality with marginal differences as late death (>1 week after trauma. Obvious and marginal discrepancies mostly occurred in the early phase of treatment, especially when severely injured patients were admitted to the emergency room undergoing continued cardiopulmonary resuscitation, i. e. limiting diagnostic procedures, and thus the clinical cause of death was essentially determined by basic emergency diagnostics. Conclusions Autopsy as golden standard to define the cause of death in fatal polytrauma varies from the clinical point of view, depending on the patient's pre-existing condition, mechanism of polytrauma, necessity of traumatic cardiopulmonary resuscitation, survival time, and thus the possibility to perform emergency diagnostics. An autopsy should be performed at least in cases of early fatal polytrauma to help establishing the definite cause of death. Moreover, autopsy data should be included in trauma registries as a quality assessment tool.

    Full Text Available We report a case of extraskeletal osteosarcoma (ESOS and autopsy findings. A 35-year-old man presented with an ossified tumor in the right thigh and lung metastasis. The lung tumors continued to develop despite multiagent chemotherapy and caused death within 8 months. Autopsy revealed many secondary lesions in the lungs, especially in the left lung. Histopathologically, the primary tumor and one of the secondary tumors showed proliferation of spindle-shaped tumor cells focally forming lace-like osteoid material. Therefore, we made a definite diagnosis of ESOS.

    Full Text Available ABSTRACTPierre Robin sequence is a neonatal disorder characterized by micrognathism, glossoptosis and cleft palate. We reported an autopsy case of a child whose malformations of the oropharynx were identified only at birth. The child was extremely preterm with severe neonatal depression and poor recovery, and the orofacial alterations prevented the correct treatment. There was facial disorder characterized by micrognathia associated with cleft palate and posterior displacement of the tongue, compressing the vallecula, structurally compatible with glossoptosis. This autopsy surpassed the scientific and epidemiological relevance, allowing the family genetic counseling and close monitoring of a subsequent pregnancy.

    We report an autopsied case of paraneoplastic necrotizing myelopathy. The patient had bilateral blindness, quadriplegia, and dyspnea of acute onset and died without remission 7 weeks later. The severe tissue necrosis and demyelination were found in the optic chiasm and from the medulla oblongata throughout the whole length of spinal cord. A papillary carcinoma was found in the thyroid gland at autopsy. In the present case IgG, myelin basic protein and activated helper T cells were increased in the CSF at onset, suggesting a mechanism of autoimmune demyelination for the condition.

    The purpose of this study was to evaluate whole-body magnetic resonance imaging (MRI) of cadavers as an adjunct to autopsy. Eight consecutive patients underwent both whole-body MRI and autopsy [either conventional (six), limited (one), or percutaneous (one)] within 24 hours of death. Comparison was made of major and minor abnormalities and predicted cause of death recorded by independent readers at both MRI and autopsy. Major discrepancies between the recorded primary cause of death at imaging and autopsy occurred in five (5) patients. These included a myocardial infarction found at autopsy alone, bowel infarction and portal venous gas found at MRI alone, and aortic dissection and occipital infarct found at MRI alone in a patient on whom only limited autopsy was performed. Postmortem MRI may represent a useful adjunct to autopsy, particularly in patients in whom autopsy is limited due to patient/family consent, inoculation risks, and ethnic doctrines.

    Full Text Available Abstract Background Computed Tomography (CT has become a widely used supplement to medico legal autopsies at several forensic institutes. Amongst other things, it has proven to be very valuable in visualising fractures of the cranium. Also CT scan data are being used to create head models for biomechanical trauma analysis by Finite Element Analysis. If CT scan data are to be used for creating individual head models for retrograde trauma analysis in the future we need to ascertain how well cranial fractures are captured by CT scan. The purpose of this study was to compare the diagnostic agreement between CT and autopsy regarding cranial fractures and especially the precision with which cranial fractures are recorded. Methods The autopsy fracture diagnosis was compared to the diagnosis of two CT readings (reconstructed with Multiplanar and Maximum Intensity Projection reconstructions by registering the fractures on schematic drawings. The extent of the fractures was quantified by merging 3-dimensional datasets from both the autopsy as input by 3D digitizer tracing and CT scan. Results The results showed a good diagnostic agreement regarding fractures localised in the posterior fossa, while the fracture diagnosis in the medial and anterior fossa was difficult at the first CT scan reading. The fracture diagnosis improved during the second CT scan reading. Thus using two different CT reconstructions improved diagnosis in the medial fossa and at the impact points in the cranial vault. However, fracture diagnosis in the anterior and medial fossa and of hairline fractures in general still remained difficult. Conclusion The study showed that the forensically important fracture systems to a large extent were diagnosed on CT images using Multiplanar and Maximum Intensity Projection reconstructions. Difficulties remained in the minute diagnosis of hairline fractures. These inconsistencies need to be resolved in order to use CT scan data of victims for

Aims: To study the incidence of invasive pulmonary aspergillosis and evaluate the predisposing factors and clinico-pathological manifestations. Settings and Design: Retrospective analysis of autopsy material from a tertiary care hospital. Material and Methods: All autopsies performed over a 12-year period were reviewed and cases with invasive aspergillosis were analysed with respect to their clinical presentation, predisposing factors, gross and histological features, complications and causes of death. Results: Among a total of 20475 autopsies performed in 12 years, 39 patients (0.19 % had invasive pulmonary aspergillosis. There were 28 males and 11 females. Their ages ranged from five months to 67 years. Dyspnoea, fever, cough with mucopurulent expectoration, chest pain and haemoptysis were commonly encountered symptoms. Forty-one per cent of the patients had no respiratory symptoms. Fungal aetiology was not entertained clinically in any of the patients. The major underlying conditions were prolonged antibiotic therapy, steroid therapy, and renal transplantation, often associated with underlying lung diseases. Pneumonia, abscesses, vascular thrombosis and infarction were common findings at autopsy. Antecedent tuberculosis, mucormycosis, Pneumocystis carinii pneumonia and Cytomegalovirus infection were also present. In most cases, death was related to extensive pulmonary involvement or fungal dissemination. Conclusion: A diagnosis of invasive pulmonary aspergillosis should always be borne in mind whenever one is dealing with recalcitrant lung infections even with subtle immunosuppression. Radiological investigations and serologic markers can be utilised for confirmation and prompt therapy.

    Reported experience with ventricular assist devices (VAD) routinely includes the rate of thromboembolic events, which is commonly calculated from clinically evident findings. Fifty-four patients have had postcardiotomy circulatory support with the Sarns centrifugal device at our institution. We have reviewed 43 patients who failed to survive VAD support to compare the thromboembolism rate diagnosed clinically to that determined at autopsy. In the 35 patients who had no autopsy, there was one clinically apparent thromboembolic event (2.3%). In eight similar patients who had autopsy, there was no clinically apparent thromboembolism. Five of these eight patients (63%) had acute thromboembolic infarcts determined at autopsy. Three had evidence of pulmonary thromboembolism, two cerebrovascular infarction, two liver infarcts, two splenic infarcts, two kidney infarcts, and one each gastric, pancreatic, prostate, adrenal, cervical, and ileal infarcts. All had left and/or right ventricular infarctions. It is concluded that patients dying following VAD have commonly suffered perioperative myocardial infarction. When evaluating complications associated with VAD, one should consider that the true incidence of thromboembolic events is underestimated by clinical findings.

    To clarify the necessity for and problems related to autopsy for determining the cause of maternal death in Japan. Women who died during pregnancy or within a year after delivery were analyzed by the Maternal Death Exploratory Committee between 2012 and 2015 in Japan. Maternal deaths were analyzed to verify the requirement of autopsy in cases in which autopsy was performed and the need for autopsy in cases in which it was not performed. Among the 49 cases performed autopsy, the final diagnosis was compatible with the clinical course in 24 cases, while the autopsy diagnosis was incompatible with the clinical course in 13 cases. In two cases, the final diagnosis was based on the clinical course, but an autopsy could exclude other possible causes. In three cases, no exact cause of maternal death was identified after autopsy. On the other hand, in cases without an autopsy, the final diagnosis was made using ante-mortem operating findings and surgical specimens in twenty-one cases. Though, thirty-one cases were estimated diagnosis based on post-mortem imaging or ante-mortem examinations, the exact original cause of death was not determined in 25 cases, and the cause of death could not be identified in eight cases without autopsy. Because in most cases the autopsy provides an exact cause of death, the necessity of autopsies should be more widely accepted in Japan.

    2002-01-01

    This article describes the first autopsy case of heme oxygenase (HO)-1 deficiency. A 6-year-old boy who presented with growth retardation; anemia; leukocytosis; thrombocytosis; coagulation abnormality; elevated levels of haptoglobin, ferritin, and heme in serum; a low serum bilirubin concentration; and hyperlipidemia was diagnosed as HO-1 deficient by gene analysis several months before death. Autopsy showed amyloid deposits in the liver and adrenal glands and mesangioproliferative glomerular changes in kidneys, in addition to an irregular distribution of foamy macrophages with iron pigments. Fatty streaks and fibrous plaques were noted in the aorta. Compared with HO-1--targeted mice, the present case seems to more severely involve endothelial cells and the reticuloendothelial system, resulting in intravascular hemolysis, disseminated intravascular coagulation, and amyloidosis with a short survival. This contrasts to the predominant iron metabolic disorders of HO-1--targeted mice with a long survival.

    ABSTRACT Autopsy imaging (Ai), postmortem imaging before necropsy, is used in human forensic medicine. Ai was performed using computed tomography (CT) for a 1-month-old Thoroughbred foal cadaver found in a pasture. CT revealed pericardial effusion, collapse of the aorta, bleeding in the lung lobe, gas in the ventricles and liver parenchyma, and distension of the digestive tract. Rupture in the left auricle was confirmed by necropsy; however, it was not depicted on CT. Therefore, Ai and conven...

    Full Text Available Acute erythroid leukemia (AEL is a rare subtype of acute myeloid leukemia(AML, characterized by predominant erythroid proliferation. The 2008 WorldHealth Organization (WHO classification of AML defined two AEL subtypes:erythroleukaemia (EL, in which erythroid precursors account for 50% or moreof all nucleated bone marrow cells and myeloblasts account for 20% or more ofthe nonerythroid cell population; and pure erythroid leukemia (PEL, in whicherythroid precursors account for 80% or more of all nucleated bone marrowcells. We report the case of an elderly female patient with wasting syndromeand pancytopenia without evidence of blasts in peripheral blood. A diagnosisof PEL was established on the basis of bone marrow biopsy findings. Thepatient died on postadmission day 20, and an autopsy was performed. Wereclassified the disease as EL on the basis of the autopsy findings, whichincluded myeloblasts accounting for more than 20% of the nonerythroid cellsin the bone marrow, as well as leukemic infiltration and myeloid metaplasia insolid organs, such as the liver, spleen, kidneys, adrenal glands, and abdominallymph nodes. A rare disease, AEL accounts for less than 5% of all AMLs and ispractically a diagnosis of exclusion. Autopsy reports of AEL are extremely rarein the literature. We demonstrate that in the case reported here, leukemia cellstended to infiltrate solid organs with myeloid metaplasia. Our findings alsoshow that a larger neoplastic bone marrow sample is crucial to the correctdiagnosis of EL, which is based on morphological and quantitative criteria.

    Cytokine storm-derived influenza-associated encephalopathy is a severe complication, affecting not only the brain but also multiple systemic organs including the heart and lungs. Hundreds of Japanese children are afflicted by influenza-associated encephalopathy every year. Influenza-associated encephalopathy can be diagnosed by pathological changes, such as advanced brain edema and disruption of astrocytic projections, which is known as clasmatodendrosis. In the present case, despite the absence of significant histopathological findings in the brain, the diagnosis of influenza-associated encephalopathy was made on the basis of autopsy findings such as brain swelling, pathological findings including diffuse alveolar damage, and increase in the concentrations of interleukin-6 in both the serum and cerebrospinal fluid. In this case, the interval from high fever to death was approximately 7 hours and may have been too short for histopathological features to develop. This is an unusual autopsy case of cytokine storm-derived influenza-associated encephalopathy without typical histopathological findings.

    Postmortem computed tomography (PMCT) is a modern tool that complements autopsy diagnostics. In clinical autopsies, a major cause of death is cardiovascular disease. To improve the performance of PMCT in cardiovascular disease, full body angiography was developed (PMCT angiography [PMCTA]). Twenty PMCTA scans generated before autopsy were compared with native PMCT and clinical autopsy. The objective of the study was to quantify the additional diagnostic value of adding angiography to native imaging and to compare PMCT and PMCTA findings to autopsy findings. The diagnosis of the cause of death was identical or overlapped in 80% of the cases that used PMCTA and 70% that used PMCT. The additional diagnostic yield given by PMCT and PMCTA in combination with autopsy was 55%. PMCT yielded additional diagnoses in the musculoskeletal system. The greatest additional diagnostic value of PMCTA was in association with cardiovascular diagnoses. The accuracy of PMCTA for cardiac causes of death was 80%, and the positive predictive value was 90%. The findings indicate that native PMCT cannot display the cardiovascular system sufficiently clearly for high-quality diagnostic assessment. However, PMCTA is a powerful tool in autopsy cases with a history of cardiovascular disease and/or a suspected cardiovascular cause of death. The combination of PMCTA and clinical autopsy enhances diagnostic quality and completeness of the autopsy report. Furthermore, in cases without consent or with a restricted consent for clinical autopsy, PMCTA has the potential to provide information on cardiovascular causes of death.

    Full Text Available Background: The study of dead is to save the livings. The growing awareness that still births and infant mortalities are unable to reduction has led to a wide spread desire for more information regarding the cause of these deaths. Congenital malformations have become important cause of fetal and neonatal (perinatal mortality in developed countries and would very soon be increasingly important determinants of fetal and neonatal mortality in developing countries like India. In spite of antenatal diagnostic modality still the fetal autopsy plays the vital role in the conformation as well as identification of congenital anomalies and also for the counseling of the parents, to prevent the fetal congenital anomalies in further pregnancies. This study was undertaken with the purpose of finding out cause of death during the perinatal period at government maternity hospital and pediatric department S.V.R.R.G.G.H. and S.V. medical college Tirupati, and to study the clinical and pathological findings (Gross and microscopic in fetal and neonatal death. Methods: The present study of congenital anomalies in fetal and neonatal deaths was done at S.V. medical college, Tirupati, over a time period of 2 years from September 2008 to 2010 August. Consent for autopsy in requested compassionately, respectfully and fully informed. The present study included dead fetus and neonates with gestational age above 20 weeks of intra uterine life and within 7 days of post natal life. All fetuses of gestational age <20 weeks and all neonates above 7 days of age were excluded from the study. The study also obtained clearance from the ethical committee of the institution. Autopsy was performed by standard technique adopted by Edith L. Potter. External and internal findings followed by histopathological examination, and autopsy findings were compared with available ultrasound findings. Results: A total of 46 Autopsies performed, 40 (87% were fetal deaths, 6 (13% were early

    A prospective study of the pattern of responses to requests for autopsy in a general surgical unit was performed. Information on the characteristics of the deceased, of the requestee and of the requester was documented in the case of 66 patients who died while in hospital. Permission to perform autopsy was not requested in 39 out of 66 cases and this was the most frequent contributory factor to the low rate of autopsy. Once a decision to grant or refuse autopsy is made by relatives of the deceased, the decision is unlikely to be reversed. Permission to perform autopsy was more likely to be sought when the deceased was male than when deceased was female. The relatives of patients who had recently undergone surgery were more likely to refuse permission for autopsy than were those of patients who had not had recent surgery.

    Medicolegal autopsy on the dead body of an elderly female revealed that the liver was having some unusual shape. The left lobe of liver was bifid, having dumb bell type morphology. Also there were some furrows which were observed over the anterior surface of the liver. This type of morphological variant has not been reported hitherto. The clinicians should be aware of developmental morphological anomalies like in this case, as they might cause confusion during the procedures like biopsy, transplantation and lobectomies. We believe that this case report is important for the clinicians who are involved in the diagnosis and management of hepatic diseases. The knowledge is also enlightening for morphologists and embryologists.

    ABSTRACT Autopsy imaging (Ai), postmortem imaging before necropsy, is used in human forensic medicine. Ai was performed using computed tomography (CT) for a 1-month-old Thoroughbred foal cadaver found in a pasture. CT revealed pericardial effusion, collapse of the aorta, bleeding in the lung lobe, gas in the ventricles and liver parenchyma, and distension of the digestive tract. Rupture in the left auricle was confirmed by necropsy; however, it was not depicted on CT. Therefore, Ai and conventional necropsy are considered to complement each other. The cause of death was determined to be traumatic cardiac tamponade. In conclusion, Ai is an additional option for determining cause of death. PMID:27703406

    Full Text Available Autopsy findings in 138 newborn infants which died in a university nursery during 3 years are reviewed and discussed. 80 per cent were premature and small- for- date newborns of up to 2500 g birth weight. Most of these cases showed in addition to general prematurely signs, respiratory tract diseases such as atelectasia, amniotic fluid aspiration and hyaline membrane disease. The full term infants died mostly of malformations. In post neonatal period the cause of death was almost entirely infections such as bronchopneumonia, gastroenteritis and septicemia.

    On the basis of an analysis of 2398 autopsies of infants aged up to 1 year in 194 cases congenital anomalies of the central nervous system were found (8.1%). Most cases of these anomalies were noted in the group of newborns (85%) and the most frequent anomalies were: myelomeningocele (35.6%), multiple anomalies (20.1%), congenital hydrocephalus (17%), anencephaly (14.4%) and corpus callosum malformations (3.6%). Myelomeningocele, congenital hydrocephalus, anencephaly and true microcephaly were more frequent in girls, while multiple anomalies and corpus callosum malformations were more frequent in boys.

    To determine the incidence, time course, and severity of pulmonary fat embolism (PFE) and cerebral fat embolism (CFE) in trauma and nontrauma patients at the time of autopsy. Prospectively, consecutive patients presenting for autopsy were evaluated for evidence pulmonary and brain fat embolism. The lung sections were obtained from the upper and lower lobe of the patients' lungs on the right and left and brain tissue. This tissue was prepared with osmium tetroxide for histologic evaluation. The number of fat droplets per high power field was counted for all sections. The autopsy reports and medical records were used to determine cause of death, time to death, injuries, if cardiopulmonary resuscitation (CPR) was attempted, sex, height, weight, and age. Fifty decedents were evaluated for PFE and CFE. The average age was 45.8 years ± 17.4 years, average body mass index was 30.1 kg/cm² ± 7.0 kg/cm², and 68% of the patients were men. The cause of death was determined to be trauma in 68% (34/50) of decedents, with 88% (30/34) blunt and 12% (4/34) penetrating. CPR was performed on 30% (15/50), and PFE was present in 76% (38/50) of all patients. Subjects with PFE had no difference with respect to sex, trauma, mechanism of injury, CPR, external contusions, fractures, head, spine, chest, abdominal, pelvic, and extremity injuries. However, subjects without PFE had significantly increased weight (109 ± 29 kg vs. 86 ± 18 kg; p = 0.023) but no difference in height or body mass index. PFE was present in 82% (28/34) of trauma patents and 63% (10/16) nontrauma patients. Eighty-eight percent of nontrauma patients and 86% of trauma patients who received CPR had PFE. Trauma patients with PFE showed no significant difference in any group. Eighty-eight percent of trauma patients died within 1 hour of injury, and 80% (24/30) of them had PFE at the time of autopsy. CFE was present only in one patient with a severe head and cervical spine injury. PFE is common in trauma patients. CPR

    Full Text Available Primary diffuse leptomeningeal gliomatosis (PDLG is a rare condition, characterized by infiltration of the meninges by glial cells without evidence of the primary tumor in the brain or spinal cord parenchyma. Glioma arising primarily from the leptomeninges is extremely rare and often diagnosed only in post mortem examination and the diagnosis may be missed in meningeal biopsy. We describe a young female who presented with symptoms of raised intracranial pressure with imaging evidence of diffuse leptomeningeal enhancement in whom autopsy confirmed the diagnosis of PDLG. Our case illustrates the diagnostic difficulties in making the pre-mortem diagnosis even with multiple cerebrospinal fluid cytologies and leptomeningeal biopsy.

    Recognition of adrenal atrophy during a review of autopsy findings in two sisters who died at 8 months and 3 1/2 years prompted estimation of very long chain fatty acids, phytanic acid and pristanic acid on wet liver fixed in formalin for 12 years. These were shown to be markedly increased and defects in multiple peroxisomal functions and decrease in particulate catalase were shown in cultured fibroblasts, confirming an abnormality of peroxisomal biogenesis. The patients had presented with failure to thrive, recurrent diarrhoea and vomiting, poor mental development, retinal pigmentation, blindness and in the older patient deafness, with only mild dysmorphic features. Autopsy in the older patient showed adrenal atrophy, cirrhosis, and foamy histiocytes in multiple organs. The brain showed no demyelination, little cytoarchitectural abnormality, occasional perivascular histiocytes in the grey matter and meninges and prominent Purkinje cells in the molecular layer of the cerebellum. In the younger patient the changes were very subtle in spite of the marked clinical similarity. Despite the young age at death the clinicopathological features are most suggestive of infantile Refsum disease. In many situations anatomical pathology can be very useful in the recognition and study of peroxisomal disorders.

    We describe a first fatal case of repellent air freshener ingestion. A 79-year-old Japanese man with Alzheimer-type senile dementia orally ingested repellent air freshener containing three surfactants: polyoxyethylene 9-lauryl ether, polyoxyethylene (40) hydrogenated castor oil, and lauric acid amidopropyl amine oxide (weight ratio of 1.3%). About 1h after the collapse, he was in cardiopulmonary arrest and subsequently died 10h after his arrival. The forensic autopsy performed 5.5h after death revealed the 380ml of stomach contents with a strong mint perfume identical to that of the repellent air freshener and the findings of acute death. Toxicologically, 9.1μg/ml and 558.2μg/ml of polyoxyethylene 9-lauryl ether were detected from the serum and stomach contents taken at autopsy. Generally, ingestion of anionic or non-ionic surfactants have been considered as safe. However, because the patient suffered from cardiac insufficiency with a low dose of repellent air freshener ingestion, medical staff members must evaluate the elderly patient for cardiac and circulatory problems regardless of the ingested dose. Not only medical and nursing staff members, but also families who are obliged to care for elderly persons must be vigilant to prevent accidental ingestion of toxic substances generally used in the household.

    2013-12-01

    Full Text Available Background: Infective endocarditis continues to challenge modern medicine despite its rare occurrence in the general population. Its incidence depends on risk groups. Correlation of anatomical and pathological findings with clinical and epidemiological elements may explain the current features of this condition. Objective: to describe the anatomical features of patients with infective endocarditis diagnosed at autopsy. Methods: A descriptive study including cases of infective endocarditis diagnosed at autopsy between 1986 and 2008 was conducted in the Provincial Clinical-Surgical Hospital Celia Sanchez, Granma. The variables analyzed were: age, sex, previous anatomical lesions, location of vegetations, multi-organ embolic infarcts and embolic abscesses, complications, culture of lesions and direct causes of death. Results: frequency of infective endocarditis diagnosed at necropsy ranged annually from 0.4 to 1.5%. Native valve endocarditis without previous damage was the most frequent. The anatomical findings were more common in the left side of the heart. Right-sided nosocomial endocarditis accounted for almost a third of the deceased patients and risk factors were identified. Embolic lesions affecting various organs, systemic complications and direct causes of death showed acute infectious endocarditis. The most common pathogen was Staphylococcus aureus. Conclusion: knowing the anatomical findings may contribute to the understanding of the clinical and epidemiological aspects of this condition. Correlation between anatomical and clinical findings was low; therefore difficulties in establishing the diagnosis during life are inferred.

The pathogenesis of GS is still unknown, but was shown to be the result that antibodies directed against glomerular basement membrane (GBM) antigens could injure both glomerular and pulmonary alveolar basement membrane. And membranous glomerulonephritis (MGN) is a glomerular disease characterized by epimembranous immune deposits and basement membrane thickening. MGN typically presents with the onset of nephrotic syndrome, but it often presents with only asymptomatic proteinuria. We reported an autopsy case of GS preceded with MGN. A 70-year-old man was admitted to our hospital with acute renal failure in May 2, 1996. Percutaneous renal biopsy demonstrated a crescentic glomerulonephritis associated with MGN and linear immunofluorescent staining of the basement membrane with antibodies to IgG. Two weeks later on admission he began to develop slight hemoptysis and chest X-ray showed pulmonary hemorrhage, Furthermore, his serum anti-GBM antibodies titer was very high. He was diagnosed as GS associated with MGN and treated with plasma exchange, glucocorticoid, and cyclophosphamide. Though his symptom was improved for intensive support, he suddenly died on June 22. Autopsied lungs showed focal pulmonary hemorrhage, but were not considered to be life-threatening. The cause of the death remained unclear.

    Full Text Available Komurcuoda leachate treatment plant, Istanbul, which consists of membrane bioreactor (MBR and nanofiltration (NF system, faced rapid flux decline in membranes after 3-year successful operation. To compensate rapid flux decline in membranes, the fouled membranes were renewed but replacement of the membranes did not solve the problem. To find the reasons and make a comprehensive analysis, membrane autopsy was performed. Visual and physical inspection of the modules and some instrumental analysis were conducted for membrane autopsy. Membranes were found severely fouled with organic and inorganic foulants. Main foulant was iron which was deposited on surface. The main reason was found to be the changing of aerator type of MBR. When surface aerators were exchanged with bottom diffusers which led to increasing of dissolved oxygen (DO level of the basin, iron particles were oxidized and they converted into particulate insoluble form. It was thought that probably this insoluble form of the iron particles was the main cause of decreased membrane performance. After the diagnosis, a new pretreatment alternative including a new iron antiscalant was suggested and system performance has been recovered.

    Current autopsy practice in forensic pathology is to a large extent based on experience and individual customary practices as opposed to evidence and consensus based practices. As a result there is the potential for substantial variation in how knowledge is applied in each case. In the present case series, we describe the variation observed in autopsy reports by five different pathologists of eight victims who died simultaneously from traumatic asphyxia due to compression during a human stampede. We observed that there was no mention of the availability of medical charts in five of the reports, of potentially confounding resuscitation efforts in three reports, of cardinal signs in seven reports and of associated injuries to a various degree in all reports. Further, there was mention of supplemental histological examination in two reports and of pre-autopsy radiograph in six reports. We inferred that reliance on experience and individual customary practices led to disparities between the autopsy reports as well as omissions of important information such as cardinal signs, and conclude that such reliance increases the potential for error in autopsy practice. We suggest that pre-autopsy data-gathering and the use of check lists specific to certain injury causes are likely to result in less deviation from evidence-based practices in forensic pathology. Pre-autopsy data-gathering and check lists will help ensure a higher degree of standardization in autopsy reports thus enhancing the quality and accuracy of the report as a legal document as well as rendering it more useful for data-gathering efforts.

    Full Text Available CONTEXT: Modern medical practice involves cost analysis of therapeutic and diagnostic procedures. There are no papers dealing with this theme in relation to forensic autopsies in our country. OBJECTIVE: Analysis of direct costs of forensic autopsies. TYPE OF STUDY: Cost analysis. SETTING: São Paulo Medical Examiner's Central Office. SAMPLE: Year 2001 activity. PROCEDURES: Routine forensic autopsies. MEAN MEASUREMENTS: Analysis of direct costs of personnel and material. RESULTS: Cost of personnel represents 90.38% or US$ 93.46. Material expenses comprised 9.62% or US$ 9.95. Total costs were calculated to be US$ 103.41. CONCLUSIONS: Forensic autopsies have a high cost. Cases to be autopsied should be judiciously selected. Our results are similar to international studies if data are rearranged based on the number of annual necropsies.

    Full Text Available Objective: The aim of the present work is to analyze the differences and similarities between the elements of a conventional autopsy and images obtained from postmortem computed tomography in a case of a homicide stab wound. Method: Comparison between the findings of different methods: autopsy and postmortem computed tomography. Results: In some aspects, autopsy is still superior to imaging, especially in relation to external examination and the description of lesion vitality. However, the findings of gas embolism, pneumothorax and pulmonary emphysema and the relationship between the internal path of the instrument of aggression and the entry wound are better demonstrated by postmortem computed tomography. Conclusions: Although multislice computed tomography has greater accuracy than autopsy, we believe that the conventional autopsy method is fundamental for providing evidence in criminal investigations.

    The rate of diagnostic error has not declined over the last 30 years despite the improvement in diagnosis methods. Today, the probability to encounter a major diagnostic change in autopsy is still high. The special autopsy that provides clinicians the necessary feedback is performed seldom in our country. This study has been started upon the claim that the malpractice cases in scope of forensic cases could be a very useful database. About 525 cases with faulty medical application that resulted in death have been encountered according to the cases that have been sent to the Forensic Medical Institution, which has been the consultative authority of the Ministry of Justice between the years 2001 and 2005. Among these, 375 cases on which autopsies have been conducted are included in the scope of the study. The cases with and without major diagnostic changes have been compared in aspects of gender, age groups, and period spent in health units. When the concordance between autopsy and clinical diagnosis for the 375 cases that were included in the study is examined, it can be seen that clinical diagnosis is verified with autopsy in 49.1% of the cases whereas neither autopsy nor clinical diagnosis was encountered in 14.7% of them. The diseases where diagnostic faults are mostly encountered are ruptured aortic aneurysm, myocardial infarction and pneumonia. The majority of the cases without a clinical diagnosis comprises of complications that occur after operations. In the study, considerable major diagnostic changes were realized after autopsy, which shows that autopsy has an important place in Turkey in spite of the improved methods of diagnosis. Also, in the cases with major diagnostic changes, the medical malpractice rate was high. This shows that autopsy is influential in revealing medical malpractice failures. In the study, we found out that the number of autopsies was high in the cases with a malpractice claim. We aim to increase this number. We are sure that such

    We report an autopsy case of bathtub drowning in epilepsy. A 26-year-old female with mental retardation had been treated for refractory epilepsy. Her younger sister found her floating supine in the bathtub 45 min after starting bathing. Neuropathological examination revealed cerebral cortical dysplasia in the precentral gyrus of the left hemisphere, which had not been detected by MRI, suggesting the etiology of epilepsy. In bathtub submersion injury of an unidentified cause, neuropathological examination should be performed to reveal any lesion underlying epileptic seizures. Additionally, we present statistics on bathtub submersion injury in children aged 5 years or older in Japan based upon nationwide survey data obtained in 1991. Forty-seven percent of them had associated epilepsy or convulsive attacks and 71% died. It is necessary for epileptic patients and their families to understand that the risk of bathtub drowning can be minimized if proper precautions are taken.

    A 57-year-old woman with acromegaly associated with mitral chordal rupture is reported. She was noted to have abnormal development in the size of her hands and feet in childhood. She occasionally suffered from shortness of breath on exertion and nocturnal dyspnea for several years, and was diagnosed and treated as having congestive heart failure due to valvular heart disease. On admission to our hospital, chordal rupture was suspected on the basis of M-mode and two-dimensional echocardiography. Seven years after discharge, she died of congestive heart failure. On autopsy, the heart weight and ventricular wall thickness were increased. Rupture of the posterior chordae was confirmed, but evidence of an old myocardial infarction was not found. There was severe interstitial fibrosis in the left ventricular wall. A possible etiology of the chordal rupture in this case was thought to be the excessive stretching caused by the disproportional visceromegaly of the heart.

    Acupuncture is one of the most popular oriental medical techniques in China, Korea and Japan. This technique is also popular as alternative therapy in the Western World. Serious adverse events are rare following acupuncture, and fatal cases have been rarely reported. A male in his late forties died right after acupuncture treatment. A medico-legal autopsy disclosed severe haemorrhaging around the right vagus nerve in the neck. Other organs and laboratory data showed no significant findings. Thus, it was determined that the man could have died from severe vagal bradycardia and/or arrhythmia resulting from vagus nerve stimulation following acupuncture. To the best of our knowledge, this is the first report of a death due to vagus nerve injury after acupuncture.

    Full Text Available BACKGROUND Autopsy is an essential auditing tool in clinical practice. The autopsy teaches us not only what is killing people right now, but points to what will kill us in the near future. This is the first autopsy study in Medical Intensive Care Unit (MICU in India as per our knowledge. METHODS Retro-prospective study of total of 141 medical autopsies of MICU deaths performed in the Department of Pathology during a period of three years. A meticulous study was performed to compare ante-mortem clinical diagnosis and post-mortem final cause of death. Cases showing a discrepancy between the clinical diagnosis and post-mortem final cause of death were categorized into IV classes according to Goldman classification. RESULTS Maximum autopsies were performed in 21-40 years (58.15%. Female preponderance noted. Non-infectious aetiology was most common cause of death (50%, of which lesions of respiratory system were the most common (33.8%. Amongst the infections, pneumonia was the most common cause of death (29.23%. Discrepancies between ante-mortem and post-mortem were noted in 63 cases (44.68%. Class I and class II discrepancies were 49.21% and 44.45%, respectively. CONCLUSION Our study stresses that routine autopsy is still very useful in MICU and emphasis must be placed on autopsy evaluation for the improvement of quality of patient care.

    The impact that a 50-minute lecture on the value of the autopsy had on the subsequent obtaining of autopsies by housestaff training in internal medicine at a teaching hospital was examined in a prospective one-year clinical trial from mid-1987 to mid-1988. The group that attended the lecture (n = 27) did not subsequently obtain a greater mean number or frequency of permissions for autopsies than did the control group (n = 26), whose members did not attend, and did not indicate more frequently in the patients' charts that autopsies had been sought. In addition, in the total group of 53 housestaff, five (9.4%) did not write a pronunciation-of-death entry, and 26 (49%) did not obtain permission for a single autopsy during the study period. Future efforts to enhance the appreciation for the autopsy among physicians in training may need to use more sophisticated techniques than a lecture in order to increase housestaff motivation to obtain consent for autopsies.

    Full Text Available Abstract Background Verbal autopsy can be a useful tool for generating cause of death data in data-sparse regions around the world. The Symptom Pattern (SP Method is one promising approach to analyzing verbal autopsy data, but it has not been tested rigorously with gold standard diagnostic criteria. We propose a simplified version of SP and evaluate its performance using verbal autopsy data with accompanying true cause of death. Methods We investigated specific parameters in SP's Bayesian framework that allow for its optimal performance in both assigning individual cause of death and in determining cause-specific mortality fractions. We evaluated these outcomes of the method separately for adult, child, and neonatal verbal autopsies in 500 different population constructs of verbal autopsy data to analyze its ability in various settings. Results We determined that a modified, simpler version of Symptom Pattern (termed Simplified Symptom Pattern, or SSP performs better than the previously-developed approach. Across 500 samples of verbal autopsy testing data, SSP achieves a median cause-specific mortality fraction accuracy of 0.710 for adults, 0.739 for children, and 0.751 for neonates. In individual cause of death assignment in the same testing environment, SSP achieves 45.8% chance-corrected concordance for adults, 51.5% for children, and 32.5% for neonates. Conclusions The Simplified Symptom Pattern Method for verbal autopsy can yield reliable and reasonably accurate results for both individual cause of death assignment and for determining cause-specific mortality fractions. The method demonstrates that verbal autopsies coupled with SSP can be a useful tool for analyzing mortality patterns and determining individual cause of death from verbal autopsy data.

    Full Text Available Thanatophoric dysplasia (TD is one of the most common lethal skeletal dysplasias, which was first designated as thanatophoric dwarfism and described in 1967. The authors report a case of a Caucasian girl with TD, born to a 31-year-old woman without comorbidities. The newborn presented respiratory distress immediately after delivery, progressing to death in less than 2 hours. An autopsy was carried out after postmortem tomographic examination. The autopsy findings depicted extensive malformations of the skeletal system and the brain. The aim of this report is to discuss the pathogenesis and correlate the morphologic features of TD that were disclosed at the tomography and the autopsy.

    We prospectively compared whole-body multidetector computed tomography (MDCT) and 3.0T magnetic resonance (MR) images with autopsy findings. Five cadavers were subjected to whole-body, 16- channel MDCT and 3.0T MR imaging within two hours before an autopsy. A radiologist classified the MDCT and 3.0T MRI findings into major and minor findings, which were compared with autopsy findings. Most of the imaging findings, pertaining to head and neck, heart and vascular, chest, abdomen, spine, and musculoskeletal lesions, corresponded to autopsy findings. The causes of death that were determined on the bases of MDCT and 3.0T MRI findings were consistent with the autopsy findings in four of five cases. CT was useful in diagnosing fatal hemorrhage and pneumothorax, as well as determining the shapes and characteristics of the fractures and the direction of external force. MRI was effective in evaluating and tracing the route of a metallic object, soft tissue lesions, chronicity of hemorrhage, and bone bruises. A postmortem MDCT combined with MRI is a potentially powerful tool, providing noninvasive and objective measurements for forensic investigations

    To explore the application value of postmortem multi-slice spiral computed tomography (MSCT) by observing and analyzing the injury features in the traffic accident victims. Ten traffic accident victims were scanned with whole body MSCT. The systemic autopsy was subsequently performed to compare with the results of MSCT. The advantages and disadvantages of autopsy and MSCT for obtaining the information of traffic accident injuries were then analyzed. MSCT could reveal 3D shape of fractures clearly and detect air accumulation in different positions of the body, which showed the obvious advantages compared with autopsy. However, the resolution of MSCT was limited compared to the detection of organ and soft tissue injuries. A combination of MSCT and autopsy is the best way for determining the manner and the cause of death in traffic fatality victims.

    Full Text Available BACKGROUND: Hypertrophic cardiomyopathy (HCM is one of the less common forms of primary cardiomyopathies. There is little data available on HCM in Indian literature. AIMS: To assess the incidence and analyse the clinicopathological features of HCM. SETTINGS: Analysis of data of 15 years from a tertiary care centre. METHODS AND MATERIAL: The clinical and pathological data in fourteen cases of HCM with respect to their gross and microscopic features and clinical presentation were reviewed. RESULTS: Incidence of HCM amongst the autopsied primary cardiomyopathies (N = 101 was 13.9% (n=14. Males were affected more. Common presenting symptoms were exertional dyspnoea, angina and palpitations. Concentric and asymmetric hypertrophy was equally seen. Obliterative small vessel disease was noted in 50% of the cases. Although significant myofibre disarray (>5% was seen in all fourteen cases, it could be demonstrated in only 40- 50% of an average of twenty sections studied. Type IA myofibre disarray was the commonest. Six of the fourteen patients died suddenly. Cardiac failure was the commonest cause of death. CONCLUSIONS: Myofibre disarray is a highly sensitive and specific marker for HCM only when considered in a quantitative rather than a qualitative fashion. In this context, the rationale for performing endomyocardial biopsy is to rule out mimics of HCM.

    The aim of this study was to describe pathologic features found at autopsy of 14 patients with penile cancer. Nine patients died from disseminated disease; 5 of them presented local/regional recurrences. Five patients died from other causes, 2 of them postoperatively. Local recurrence sites were corpus cavernosum, Buck's fascia and urethra, regional skin, and prostate. Metastatic sites were lymph nodes (9 cases), liver (7 cases), lungs (6 cases), heart (5 cases), adrenals, bone and skin (3 cases each), thyroid and brain (2 cases each), and pancreas, spleen, and pleura (1 case each). Patients with heart metastasis had arrhythmias. Patients who died and who did not die from penile cancer had different profiles: low-grade superficial tumors with usual and warty subtypes versus high-grade deeply invasive basaloid or hybrid verrucous/sarcomatoid carcinomas. A natural history model for penile cancer routes of spread is proposed: local intrapeneal, regional and systemic nodes, regional skin, liver, lungs, heart, and other multiple sites.

  9. Prune-belly syndrome: an autopsy case report

    Full Text Available Prune-belly syndrome (PBS is a rare congenital anomaly characterized by a spectrum of mild-to-severe presentations of urinary tract malformations, deficient abdominal wall musculature, and cryptorchidism in male newborns or genital abnormalities in the female newborns. Currently, antenatal diagnosis is feasible with ultrasound examination, and treatment is based on case report experience. More recently, intrauterine management has been undertaken with encouraging results. The authors report a case of PBS diagnosed at the seventeenth gestation week, when ultrasonographic examination revealed the presence of ascites, distended bladder, thickened bladder wall and posterior urethral valve. The fetus was submitted to an intrauterine intervention at the nineteenth gestational week. Delivery occurred at 34 weeks of gestation and the newborn examination was consistent with PBS. On the second day of life, the newborn was submitted to abdominoplasty, colostomy, and orchiopexy. However, the outcome was unfavorable with respiratory failure and death on the fifteenth day of life. The autopsy confirmed the diagnosis of PBS, but the immediate cause of death was attributed to aspiration pneumonia.

    The aim of this study was to compare the patterns of grey and white matter atrophy on MRI in autopsy confirmed progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD), and to determine whether the patterns vary depending on the clinical syndrome. Voxel-based morphometry was used to compare patterns of atrophy in 13 PSP and 11 CBD subjects and 24 controls. PSP and CBD subjects were also subdivided into those with a dominant dementia or extrapyramidal syndrome. PSP subjects showed brainstem atrophy with involvement of the cortex and underlying white matter. Frontoparietal grey and subcortical grey matter atrophy occurred in CBD. When subdivided, PSP subjects with an extrapyramidal syndrome had more brainstem atrophy and less cortical atrophy than CBD subjects with an extrapyramidal syndrome. PSP subjects with a dementia syndrome had more subcortical white matter atrophy than CBD subjects with a dementia syndrome. These results show regional differences between PSP and CBD that are useful in predicting the underlying pathology, and help to shed light on the in vivo distribution of regional atrophy in PSP and CBD.

    The verbal autopsy (VA) questionnaire is a widely used method for collecting information on cause-specific mortality where the medical certification of deaths in childhood is incomplete. This paper discusses review by physicians and expert algorithms as approaches to ascribing cause of deaths from the VA questionnaire and proposes an alternative, data-derived approach. In this validation study, the relatives of 295 children who had died in hospital were interviewed using a VA questionnaire. The children were assigned causes of death using data-derived algorithms obtained under logistic regression and using expert algorithms. For most causes of death, the data-derived algorithms and expert algorithms yielded similar levels of diagnostic accuracy. However, a data-derived algorithm for malaria gave a sensitivity of 71% (95% Cl: 58-84%), which was significantly higher than the sensitivity of 47% obtained under an expert algorithm. The need for exploring this and other ways in which the VA technique can be improved are discussed. The implications of less-than-perfect sensitivity and specificity are explored using numerical examples. Misclassification bias should be taken into consideration when planning and evaluating epidemiological studies. PMID:8706229

    Full Text Available Introduction:In our study, our aim was to reveal the relationship between subendocardial hemorrhage (SEH  which can be seen macroscopically immediately beneath the endocardium, and emerge secondary to many conditions from direct cardiac,  head, and abdominal traumas to hyperemia, and its location with cause of death, its diagnostic value (if any, and whether it can be evaluated as a vital finding.Material and Method :285 autopsy cases diagnosed as SEH which were brought to the Group Presidency of Morgue Specialization Department of the State Institute of Forensic Medicine of Bursa  were included in the studyResults: Study population consisted of 229 (80.4 % male, and 56 (19.6 % female patients. Thity-one cases of death were related to natural causes, while the most frequently detected pathological causes of death were isolated abdominal traumas (32.9 %, followed by isolated head traumas (31.9 %.  While traffic accidents ranked first (35.1% among the events leading to death. Among evaluated cases, SEH was mostly located on septum.Discussion: To fully understand the yet inadequately elucidated pathogenic mechanisms  of SEH , it should be accurately defined by histopathological analysis. Even though various causes of death seen  in association with these lesions suggest more than one underlying pathogenic mechanism, because of their nonspecific characteristics, their possible roles as indicators of vitality (if any should be reinforced  by further studies.

    We examined 26 autopsy-proven cases of intracranial malignant lymphoma (IML) in immunocompetent patients to determine the extent of neoplastic involvement of the central nervous system (CNS) and to evaluate the effects of radiation on the tumor and brain tissue. All tumors were identified as diffuse non-Hodgkin's lymphomas of B-cell origin. In six patients who had not received radiotherapy, the clinical course of the disease was short and extensive infiltration of the tumor was seen. The remaining 20 patients were treated with radiotherapy and had a longer survival time. Leptomeningeal involvement was common, but extensive subarachnoid proliferation of the tumor was seen in only two cases. The posterior, but not anterior, lobe of the pituitary was involved in 5 of 22 cases, and choroid plexus involvement was seen in 4 of 21. Direct invasion of the tumor into the spinal cord, which tended to occur in patients with posterior fossa masses, was observed in 5 of 21 cases. Following irradiation, coagulation necrosis was frequently found in the invading zone as well as in the tumor mass, and degeneration of the white matter was also seen. We suggest that IML can extensively infiltrate into the CNS, including the posterior lobe of the pituitary and spinal cord, and that radiation injury to the brain appears to occur relatively easily in this disease.

    An autopsy case is reported here of a 69-year-old patient with schizophrenia, who was known retrospectively to have had a prefrontal lobotomy 32 years previously. The patient was diagnosed as schizophrenic at the age of 24 and the lobotomy was undertaken 13 years later. The patient was recently found outside in a dehydrated condition and admitted to a general hospital, where he died of respiratory failure. Bilateral cystic lesions were found in the deep white matter of the frontal lobe. The cyst walls consisted of glial fibrous tissues, and severe demyelination with axonal destruction was diffusely observed in the white matter of the frontal lobe. In the thinner frontal cortex without arcuate fibers (U fibers) close to the cavities, cytoarchitectural abnormalities were observed. In the thalamic nuclei marked retrograde degeneration and astrocytic gliosis were observed. The detailed neuropathological findings of a lobotomized schizophrenic brain are reported here. It is proposed that one should be reminded of a lobotomized brain if bilateral cysts are found.

    The major component of car washer fluid is a methanol. Intracranial hemorrhage is a rare but lethal complication in methanol poisoning. We report a case of massive bilateral basal ganglia hematoma in a 32-year-old man with methanol poisoning. He drank car washer solution twice time (about 500 ml), and was admitted to a territorial hospital 10 hours post-ingestion for depressed mental status, lower blood pressure, and high anion gap metabolic acidosis. Computed tomographic (CT) scan showed lesions in both putamen and cerebral deep white matter. Twenty-one days after methanol exposure, he suddenly developed cardiorespiratory arrest. In autopsy, external examination revealed moderate cerebral edema, but no evidence of herniation. Coronal sections of the brain showed softening and about 34 g hematoma in the bilateral putamen and 3rd ventricles. The toxic effect of methanol on the visual system has been noted in the absence of neurologic manifestations; however, there have also been a report of concomitant brain in Korea.

    We report an autopsy case of a 42-year-old woman who, when discovered, had been dead in her apartment for approximately 1 week under circumstances involving treachery, assault and possible drug overdose. This case is unique as it involved two autopsies of the deceased by two different medical examiners who reached opposing conclusions. The first autopsy was performed about 10 days after death. The second autopsy was performed after an exhumation approximately 2 years after burial. Evidence collected at the crime scene included blood samples from which DNA was extracted and analysed, fingerprints and clothing containing dried body fluids. The conclusion of the first autopsy was accidental death due to cocaine toxicity; the conclusion of the second autopsy was death due to homicide given the totality of evidence. Suspects 1 and 2 were linked to the death of the victim by physical evidence and suspect 3 was linked by testimony. Suspect 1 received life in prison, and suspects 2 and 3 received 45 and 20 years in prison, respectively. This case indicates that cocaine toxicity is difficult to determine in putrefied tissue and that exhumations can be important in collecting forensic information. It further reveals that the combined findings of medical examiners, even though contradictory, are useful in determining the circumstances leading to death in criminal justice. Thus, this report demonstrates that such criminal circumstances require comparative forensic review and, in such cases, scientific conclusions can be difficult.

    Background Aquired immune deficiency syndrome (AIDS) presents a challenge to medical researchers because of its unique pathological and clinical picture. The clinical data, particularly autopsy evidence, from China have failed to provide enough pathological and etiological evidence for AIDS diagnosis, which impairs the reliability of the diagnosis and our full understanding of the occurrence and development of AIDS complications. The purpose of this study was to investigate the imaging and pathologic characteristics of AIDS.Methods Autopsy, imaging and pathological data from 8 cases of AIDS were retrospectively analyzed. Routine CT scanning of different body parts was performed during their periods of hospitalization. Transverse CT scanning was conducted from the skull to the pelvis immediately after the occurrence of death. After routine formalin fixing, 7 cardevers were cross sectioned for autopsy in freezing state and 1 for gross autopsy. Tissues were obtained from each section and organs for pathological examinations.Results The autopsy data indicated the presence of parasitic infections, bacterial infections, fungal infections, and virus infections in AIDS patients. Pneumocystis pneumonia, pulmonary tuberculosis, coccobacteria pneumonia, Aspergillus pneumonia, cytomegalovirus pneumonia, toxoplasma encephalitis, lymphoma and cerebrovascular diseases were found in these patients.Conclusions During the course of AIDS progression, the concurrent multiple infections as well as tumor development may result in multiple organ pathological changes and clinically complex symptoms that further complicate the imaging and pathological manifestations, thus resulting in difficult differential diagnosis. A combination of imaging data and autopsy data can help to clarify the diagnosis.

    Full Text Available Context: With the continuing rise in the number of immunocompromised patients, the incidence of invasive mycoses has increased. Various studies have reported the trends of fungal infections in autopsies. Because of limitations in antemortem clinical diagnosis owing to lack of sensitive diagnostic tools, information regarding frequency and pathogenesis of fungal infections is largely dependent on autopsy studies. Aim: To study the prevalence of fungal infections at autopsy spanning a period of 20 years and to document recent trends, prevalence of various fungi over decades along with underlying predisposing factors and pathological findings. Settings and Design: Retrospective study. Materials and Methods:All autopsies between 1988 and 2007 were reviewed and all cases showing fungal infections were analyzed. The clinical details and demographic data were retrieved from medical records. Representative sections from all organs were stained with hematoxylin and eosin stain and special stains including Gomori′s silver methenamine (GMS and per-iodic acid Schiff (PAS. Culture details were noted, wherever available. Results: A total of 401 autopsies were performed during the study period. Fungal infections were identified in 35 (8.7% of these cases. Leukemia was the commonest risk factor. The commonest pathogen in the present study was Aspergillus sp. The commonest single organ involved was brain (n = 18. Culture positivity was seen in 23.8% cases. Conclusion: The study highlights various predisposing factors and organisms in autopsy series. Existing diagnostic modalities are not sensitive to ensure antemortem diagnosis of fungal infections.

    National differences in the legislation on cause and manner of death investigation are reflected in a high autopsy rate in suicides in Finland and a low corresponding rate in Denmark. The consequences for mortality statistics of these different investigation practices on deaths classified as suicides in Denmark and Finland, respectively, are not known in detail. The aim of this article was to analyse autopsy rates in deaths classified as suicides, and to identify any differences in investigation practices in deaths with a comparable cause of death, but classified as unnatural deaths other than suicide. Data from the mortality registries were summarised for the years 2000, 2005 and 2010. Autopsy rates (total, forensic and medical) were analysed with regard to deaths classified as suicide, and they were compared for three age groups (1-50 years, 51-70 years and ≥71 years) and for causes of death. Deaths classified as suicide were compared with other unnatural classifications, and comparable causes of death were coded into six subgroups: poisonings, suffocations/strangulations, firearm discharges, drowning/submersions, explosions/flames and other/unspecified causes. The total autopsy rate for suicides was 99.8% in Finland and 13.2% in Denmark. Almost all of these autopsies were conducted as forensic autopsies. In the age group ≥71 years, Danish suicides outnumbered Finnish suicides (410 versus 283). The total autopsy rate was lower in the more senior age group in Denmark (19.5%, 9.9%, 5.6%), whereas it was consistently high in Finland (99.8%, 99.9%, 99.6%). Among Danish deaths due to poisonings, the autopsy rate was 89.5% when these were classified as accidents, but only 20.7% for cases classified as suicides. The number of deaths in the two Danish subgroups was comparable (550 versus 553). In Denmark, the decision regarding the need, if any, for a forensic autopsy is made during the external forensic examination of the body. Our study showed that the limited use

    Full Text Available Background: The incidence of ischemic heart disease (IHD has markedly increased in India over the past few years. Considering the variations in racial, dietary and lifestyle patterns in our population, it is essential to study the biology of coronary atherosclerosis in our patients. Vulnerable plaques have a large number of foam cells, extracellular lipid, thin fibrous caps and clusters of inflammatory cells and are more prone to rupture. These plaques are nourished by the microvessels arising from the vasa vasorum of the blood vessels and by lumen-derived microvessels through the fibrous cap. This autopsy study was designed to analyse the coronary arterial tree in cases of sudden cardiac death, classify coronary atherosclerotic plaques and to assess the factors contributing to vulnerability of the plaques including inflammation, calcification and microvascular density. Materials and Methods: Seven cases of sudden cardiac death were included in the study. The hearts were perfusion-fixed and the coronary arteries along with their main branches were dissected and studied. The location of the plaques, type of plaques, presence of inflammation and calcification were assessed. The cap thickness and microvessel density per 1000um 2 were assessed. The statistical significance was estimated. Results and Conclusions: Extensive high-grade coronary atherosclerotic disease was seen in all sudden cardiac death cases. Majority of the plaques were vulnerable. High-grade inflammation was seen in most of the vulnerable and ruptured plaques. All the ruptured plaques were uncalcified indicating that calcification probably stabilizes the plaques and protects against rupture. Increased microvessel density was noted in ruptured plaques compared to vulnerable plaques. However, it was not statistically significant.

    In a series of 235 autopsies, changes in the subcapscular thoracic fascia similar to elastofibroma dorsi (Järvi & Saxen 1959, -et al. 1969) were found in 39 cases, all at least 58 years old. In people over 55 years, the frequency was 24.4 per cent in females and 11.2 per cent in males. In addition to hypertrophy and secondary degeneration of elastic fibres, necrosis of collagenous-, adipose-, muscular-, and nervous tissue, as well as formation of clefts, cysts and bursae was found in 85 per cent of cases presenting elastic changes--both in connection with them and outside the degenerated areas--as well as in 39 per cent of cases where no elastic degeneration occurred. Other changes included extensive scarring of the tissue, followed by reduction of fat and, more seldom, oedema and inflammatory infiltration. Breaks in the elastic cage, necrosis and fibrosis of arterial walls were found in 44 per cent of cases of elastic degeneration and in 14 per cent of cases without degeneration. In veins, more extensive wall fibrosis occurred, leading to necrosis; in cases of elastic degeneration the adventitial elastic network was also involved. Venous changes were found in 90 per cent of the cases of elastic degeneration and in 30 per cent of cases without degeneration. Direct mechanical stress on elastic tissue may be an important cause of hypertrophy and secondary degeneration of elastic fibres, and also of diffuse increase of collagenous tissue. On the other hand, nutritional deficiency due to failing resistance of the vascular system against friction of the scapula and streching movements of the upper extremities may play a main part in necrotic tissue changes.

    Epilepsy is a common chronic neurological disorder characterized by seizures. Mortality is significantly increased in patients with epilepsy. Sudden unexpected death in epilepsy (SUDEP) is the most common seizure-related category of death. A retrospective study of forensic autopsy cases from 2007 to 2009 at the Office of the Chief Medical Examiner (OCME) yielded a total of 104 sudden unexpected deaths directly or indirectly caused by an epilepsy/seizure disorder in the State of Maryland. Of these deaths, 74 cases met a general accepted definition of SUDEP. The age of SUDEP individuals ranged from 14 to 63 with the majority of subjects in the ages between 21 and 50 years (58 cases, 78.4%). Males were slightly more likely than females to die of SUDEP (male:female=1.5:1 based on the rate). The onset age of epilepsy was documented in 47.3% of cases (35/74) based on investigation and medical records. Of the 35 cases, 12 subjects had early onset epilepsy (onset ages 1-15 years) and 20 subjects had duration of epilepsy for more than 10 years. The majority of deaths (61 of the 74 cases, 82.4%) were unwitnessed. Death scene investigation showed that 71 deaths (95.9%) occurred inside their residence with 50 subjects (70.4%) found either in bed or on the bedroom floor near the bed. Forty-three out of 74 cases (58.1%) showed neuropathological lesions. Per history, 50 subjects were reported as being on anti-epileptic drugs (AEDs). However, postmortem toxicological analysis revealed that only 26 subjects (35.1%) had detectable AEDs. Of the 74 cases, seizure disorder or epilepsy was listed as primary cause of death in 66 cases and the term of SUDEP as official cause of death in only 8 cases. This report focuses on the characteristics of death scene investigation and postmortem examination findings of SUDEP cases.

The content of the research consists of the interaction of culture, information, digital culture, intellectual technologies, and digital library concepts. The study is an entry work to integrity of digital culture and digital library theories and aims to expand the symmetry. The purpose of the study is to emphasize the relation between the digital culture and digital library theories acting intersection of the subjects that are examined. Also the perspective of the study is based on examining the literature and analytical evaluation in both studies (digital culture and digital library. Within this context, the methodology of the study is essentially descriptive and has an attribute for the transmission and synthesis of distributed findings produced in the field of the research. According to the findings of the study results, digital culture is an inclusive term that describes the effects of intellectual technologies in the field of information and communication. Information becomes energy and the spectrum of the information is expanding in the vertical rise through the digital culture. In this context, the digital library appears as a new living space of a new environment. In essence, the digital library is information-oriented; has intellectual technology support and digital platform; is in a digital format; combines information resources and tools in relationship/communication/cooperation by connectedness, and also it is the dynamic face of the digital culture in time and space independence. Resolved with the study is that the digital libraries are active and effective in the formation of global knowing and/or mass wisdom in the process of digital culture.

    The aim of this study was to assess the role of postmortem computed tomography (PMCT) as an alternative for autopsy in determining the cause of death and the identification of specific injuries in trauma victims. A systematic review was performed by searching the EMBASE and MEDLINE databases. Articles were eligible if they reported both PMCT as well as autopsy findings and included more than one trauma victim. Two reviewers independently assessed the eligibility and quality of the articles. The outcomes were described in terms of the percentage agreement on causes of death and amount of injuries detected. The data extraction and analysis were performed together. Fifteen studies were included describing 244 victims. The median sample size was 13 (range 5-52). The percentage agreement on the cause of death between PMCT and autopsy varied between 46 and 100%. The overall amount of injuries detected on CT ranged from 53 to 100% compared with autopsy. Several studies suggested that PMCT was capable of identifying injuries not detected during normal autopsy. This systematic review provides inconsistent evidence as to whether PMCT is a reliable alternative for autopsy in trauma victims. PMCT has promising features in postmortem examination suggesting PMCT is a good alternative for a refused autopsy or a good adjunct to autopsy because it detects extra injuries overseen during autopsies. To examine the value of PMCT in trauma victims there is a need for well-designed and larger prospective studies. (orig.)

  8. Evaluating the Cause of Death in Obese Individuals: A Ten-Year Medical Autopsy Study

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Background. Obesity is a growing public health problem associated with increased morbidity and rate of death. Postmortem examination is imperative to determine the cause of death, to detect clinically unsuspected disease entities, and consequently to determine the actual impact of obesity on patient mortality. Methods. A total of 849 adult autopsies were retrospectively reviewed. Obese (BMI ≥ 30 kg/m2 and nonobese patients were separately studied. The primary cause of death in each group was categorized into malignancy, infection, stroke, ischemic and nonischemic heart disease, pulmonary embolism, hemorrhage, and primary nonneoplastic diseases of different organ systems. Results. Of 849 autopsies, 32.3% were obese. The leading causes of death in the obese population were malignancy (31.4%, infection (25.9%, ischemic heart disease (12.8%, and pulmonary embolism (6.2%. Obese individuals were statistically more likely to die from pulmonary embolism and liver disease and less likely to die from neurologic diseases and nonischemic heart disease. Conclusion. Autopsies on obese individuals constitute a third of all adult medical autopsies in our center. Increased death rates in the obese due to pulmonary embolism and liver disease should receive special clinical attention. Autopsy findings in the obese population should contribute to overall premortem disease detection, prevention, and management.

  9. Student perceptions of medico-legal autopsy demonstrations in a student-centred curriculum.

    Teaching autopsies in undergraduate medicine, although traditionally considered valuable by both educators and students, have been marginalised in modern curricula. This study explored medical students' experiences of the medico-legal autopsy demonstrations which formed part of their training in forensic medicine. In this phenomenological study, qualitative data obtained by interviewing 10 Year 4 medical students from various socio-cultural backgrounds were interpretively examined. One-to-one, semi-structured interviews were tape-recorded and transcribed. The data were thematically organised and then analysed using a theoretical framework of three dimensions of learning, namely, cognitive, emotional and societal. Students still perceive autopsies as essential even in the context of self-directed learning. They identified a better understanding of anatomy and traumatology as the main cognitive benefits. At an emotional level students felt they had developed a degree of clinical detachment and would be better equipped to deal with issues surrounding death. Although socialisation influenced students' feelings about the autopsy, it did not detract from their appreciation of the educational value of the experience. The results support previous findings from both students, prior to curriculum reform, and medical educators who were canvassed for their opinions in relation to a modern curriculum. Besides the obvious cognitive advantages, educators should be mindful of the hidden curriculum that emanates from autopsies because it impacts on the development of professionalism and ethical behaviours of future medical practitioners.

    Religious beliefs and cultures have influenced treatment of dead bodies in different ways by nations throughout history, and attitudes toward the deceased individuals have changed across time and so has the role and mechanism of autopsy. Islam has been a part of Europe for a long time; therefore, we would like to emphasize the important issues for Muslims and their families regarding death, autopsy, and funeral and to describe international perspectives of Muslim autopsies. Muslims have expressed their views on autopsy publically and internationally, and there have been claims of violation of the deceased, delays in burial, and nonconsideration of their religious beliefs. In this article, we aim to increase awareness and understanding of doctors about the religious and ethical issues important to Muslims and their families, so that appropriate considerations may be made where possible with regard to respectful treatment of deceased loved ones to decrease tensions presently being faced. Forensic medicine doctors could assist by undertaking autopsy without delay, in a private room by those of the same sex, and covering parts of the body not being worked on at that time.

    Mountain climbing is a popular recreational activity with a growing number of participants and associated fatalities. To define the characteristics of these fatal incidents and the typical autopsy findings in the victims, we reviewed the autopsy and investigative findings of all fatalities that occurred on Mount Rainier from 1977 through 1997. A total of 50 deaths occurred in 29 separate incidents. Fifty-eight percent of accident victims died as the result of a fall; another 34% died as a result of an avalanche. The incidents leading to death occurred at an average altitude of 3652 m (11,977 feet); range, 2073 to 4389 m (6800-14,400 feet). The average age of the victims was 31.2 years (range, 17-55 years), and 47 of the 50 were men (94%). Bodies were not recovered in 13 cases (26%). Autopsies were performed in 30 of the remaining 37 cases. At autopsy, the cause of death was ascribed to multiple injuries in 12 cases (40%), isolated head and neck injuries in 7 cases (23%), and chest injuries in 1 case (3%). Asphyxia and hypothermia were the cause of death in 8 cases (27%) and 2 cases (7%), respectively. The frequency of specific injuries is presented by anatomic region. The unique autopsy and investigative features of mountaineering deaths are discussed.

    Autopsies are the gold standard for diagnostic accuracy; however, no recent study has analyzed autopsies in heart failure (HF).We reviewed 1241 autopsies (January 2000-May 2005) and selected 232 patients with HF. Clinical and autopsy diagnoses were analyzed and discrepancies categorized according to their importance regarding therapy and prognosis.Mean age was 63.3 ± 15.9 years; 154 (66.4%) patients were male. The causes of death at autopsy were end-stage HF (40.9%), acute myocardial infarction (17.2%), infection (15.9), and pulmonary embolism 36 (15.5). Diagnostic discrepancies occurred in 191 (82.3%) cases; in 56 (24.1%), discrepancies were related to major diagnoses with potential influence on survival or treatment; pulmonary embolism was the cause of death for 24 (42.9%) of these patients. In 35 (15.1%), discrepancies were related to a major diagnosis with equivocal influence on survival or treatment; in 100 (43.1%), discrepancies did not influence survival or treatment. In multivariate analysis, age (OR: 1.03, 95% CI: 1.008-1.052, P = 0.007) and presence of diabetes mellitus (OR: 0.359, 95% CI: 0.168-0.767, P = 0.008) influenced the occurrence discrepancies.Diagnostic discrepancies with a potential impact on prognosis are frequent in HF. These findings warrant reconsideration in diagnostic and therapeutic practices with HF patients.

    Cases of sudden unexplained death in childhood (SUDC) in Ireland in children aged >1year and <5 years were examined in order to assess the quality of autopsy reporting. All SUDC cases are notified to and documented by the National Sudden Infant Death Register (NSIDR) in Ireland along with all cases of sudden infant death syndrome (SIDS) referring to sudden infant deaths less than one year of age. The database of the NSIDR in Ireland was interrogated and cases of SIDS and SUDC were compared over a fifteen-year period (1995-2009). SIDS cases whose autopsies were conducted in the same hospital in the same year as the index SUDC case were used for comparison. The autopsy report for each case was examined and modified Rushton(MR) scores 1\\r\

    An 84-year-old woman, who was followed up as hypertrophic obstructive cardiomyopathy (HOCM) in a local hospital, was transferred to our center because of anterior chest pain and diagnosed with acute myocardial infarction (MI). Coronary angiography showed total occlusion of the mid-left anterior descending, and flow was restored after endovascular thrombectomy. An autopsy was performed after she died on hospital day 6. At autopsy, there was no significant stenosis in this vessel and the absence of plaque rupture was confirmed. Likewise, it was unclear asymmetric hypertrophy at autopsy, it could not deny that a sigmoid deformity of the basal septum occurs in elderly patients and can mimic the asymmetric septal hypertrophy of hypertrophic cardiomyopathy. MI was thought to be caused by coronary spasm or squeezing in HOCM-like heart. Therefore, it may be necessary antithrombosis therapy in HOCM-like patients with no history of paroxysmal atrial fibrillation.

    2014-01-01

    Mucormycosis is an increasingly important cause of morbidity and mortality for patients with hematological malignancies. The diagnosis of mucormycosis usually requires mycological evidence through tissue biopsy or autopsy because the signs and symptoms are nonspecific and there are currently no biomarkers to identify the disease. We herein present two autopsied cases of acute myeloid leukemia with prolonged neutropenia who developed invasive mucormycosis accompanied by pulmonary artery embolism. Our cases were featured by unexplained fever and rapidly progressive dyspnea. Computed tomography scan detected nodular lesions or nonspecific consolidations in the lungs. Cultures, cytological study, and serum fungal markers consistently gave negative results. Autopsy revealed embolism of the pulmonary artery which consisted of fibrin clots by filamentous fungi. Genomic DNA was extracted from the paraffin-embedded clots and was applied to polymerase chain reaction amplification, leading to the diagnosis of infection by Rhizopus microsporus. We should carefully search for life-threatening pulmonary embolism when patients with hematological malignancies develop pulmonary mucormycosis.

    Detailed fatal injury data after fatal motor vehicle crashes (MVC) are necessary to improve occupant safety and promote injury prevention. Autopsy remains the principle source of detailed fatal injury data. However, procedure rates are declining because of a range of technical, ethical, and religious concerns. Postmortem computed tomography (PMCT) is a potential alternative or adjunct to autopsy which is increasingly used by forensic researchers. However, there are only limited data regarding the utility of PMCT for analysis of fatal MVC injuries. We performed whole body PMCT and autopsy on six subjects fatally injured in MVC in a single county in Michigan. All injuries detected by either method were coded using the Abbreviated Injury Scale (AIS). Severe injuries, defined as AIS 3 or higher (AIS 3+), were tallied for each forensic procedure to allow a comparison of relative diagnostic performance. A total of 46 AIS 3+ injuries were identified by autopsy and PMCT for these cases. The addition of PMCT to autopsy increased overall detection of AIS 3+ injuries (all types) by 28%. PMCT detected 27% more AIS 3+ skeletal injuries than autopsy but 25% less soft tissue injuries. Use of PMCT improves the detection of AIS 3+ injuries after fatal MVC compared with isolated use of autopsy and also produces a highly detailed permanent objective record. PMCT appears to improve detection of skeletal injury compared with autopsy but is less sensitive than autopsy for the detection of AIS 3+ soft tissue injuries. Neither autopsy nor PMCT identified all AIS 3+ injuries revealed by the combination of the two methodologies. This suggests that PMCT should be used as an adjunct to autopsy rather than a replacement whenever feasible.

    Full Text Available Abstract Background Registration of the fact of death is almost complete in the city of Chennai and not so in the rural Villupuram district in Tamilnadu, India. The cause of death is often inadequately recorded on the death certificate in developing countries like India. A special verbal autopsy (VA study of 48 000 adult (aged ≥ 25 yrs deaths in the city of Chennai (urban during 1995–97 and 32 000 in rural Villupuram during 1997–98 was conducted to arrive at the probable underlying cause of death to estimate cause specific mortality. Methods A ten day training on writing verbal autopsy (VA report for adult deaths was given to non-medical graduates with at least 15 years of formal education. They interviewed surviving spouse/close associates of the deceased to write a verbal autopsy report in local language (Tamil on the complaints, symptoms, signs, duration and treatment details of illness prior to death. Each report was reviewed centrally by two physicians independently. Random re-interviewing of 5% of the VA reports was done to check the reliability and reproducibility of the VA report. The validity of VA diagnosis was assessed only for cancer deaths. Results Verbal autopsy reduced the proportion of deaths attributed to unspecified and unknown causes from 54% to 23% (p Conclusion A ten day training programme to write verbal autopsy report with adequate feed back sessions and random sampling of 5% of the verbal autopsy reports for re-interview worked very well in Tamilnadu, to arrive at the probable underlying cause of death reliably for deaths in early adult life or middle age (25–69 years and less reliably for older ages (70+. Thus VA is practicable for deaths in early adult life or middle age and is of more limited value in old age.

  5. How can we ensure that the coroner's autopsy is not an invasion of human rights?

    Despite public inquiries, and some changes to legislation following high-profile multiple homicides that were not detected by autopsy, coroners continue to rely largely on the autopsy. Regardless of the extent of quality failings and excess deaths at some hospitals, not detected through the coroner system, the autopsy is scarcely used by hospitals to monitor standards and educate. To explore when a compulsory medicolegal autopsy should, and should not, be used. Two hundred and thirty-six cases referred to a senior coroner were evaluated by pathologists with long experience of forensic, coronial and hospital autopsies, using detailed antecedent medical and circumstantial information: after their advice, the senior coroner decided what kind of autopsy provided sufficient information for his purposes. In nearly 40% (n=88) of deaths where the senior coroner accepted jurisdiction, issues raised could be resolved through analysis of medical records and antecedent information, supplemented only by detailed external examination of the body. Timely provision of sufficient information allows informed decisions about the requirement for, and nature and extent of, medical investigations into a death: unnecessary post mortem dissection is avoided, protecting the rights, under Articles 8 and 9 of the Human Rights Act 1998, of the bereaved to privacy, family life and religious practice. Although improvements in healthcare can undoubtedly result from detailed coroners' inquiries, those deaths where the matters investigated relate only to the accuracy of a natural cause of death or sit with a healthcare provider's internal quality assurance, should be investigated by the healthcare system in collaboration with the bereaved. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    1992-03-01

    Autopsy data indicate that urolithiasis is found in 3.6% of 100 autopsies, most frequently in men (62 cases) over 40 years of age. In 2/3 of patients the length of the disease was under 8 years, rarer over 15 years. In most cases renal involvement was bilateral (72 patients). In more that 70% two or three operations were performed. A pathogenetic relationship was found between urolithiasis and malformations of the kidneys and ureters, urinary stasis in disorders of innervation of lesser pelvis organs, hyperplasia of the prostate and disorders of the mineral metabolism.

  7. Plutarcho De liberis educandis: kaip išugdyti dorą pilietį? | Plutarch‘s De liberis educandis: Educating the Virtuous Citizen

    Directory of Open Access Journals (Sweden)

    Monika Voinič

    2012-01-01

    Full Text Available Education is an important topic in Plutarch’s corpus. Three first treatises of Moralia – De liberis educan­dis, De audiendis poetis and De audiendo – have the education of children as their main topic. In these works, education is presumed to be a key aspect in developing the character; good education promotes good behavior and a virtuous character; on the con­trary, poor or insufficient education gives corre­spondingly negative results. The author of the article focuses on the first treatise, De liberis educandis, which is commonly believed to be not of the Plu­tarch’s authorship, however, till now it is included in the Moralia corpus because of its high importance and influence it had under the name of Plutarch.Firstly, attention is drawn to the structure and the main ideas presented in the treatise. A special atten­tion is drawn to the role of the family in raising and educating children of the youngest age. The most vi­tal period for the formation of character is claimed to be in childhood: thus, the importance of good educa­tion in Plutarch’s, as well as in Platonic thought, is that the character of the child is molded by reason. Closely connected with the notion of training of the irrational is the distinction which Plutarch observes between nature (physis and character (êthos. A per­son’s nature is what he is born with and is unchang­ing. A person’s character is related to his nature, but is produced and affected by the extent to which rea­son influences it through quality education, and by the of his life.Plutarch assumes that the character in earliest childhood or youth is in the process of formation. Nature provides the raw material, but education and childhood, and habits more generally, play a deter­mining role in the formation of thes adult character. By adulthood, a settled character has been attained, although the adult character may still be improved through continuing the application of reason and good

    Full Text Available Background: Autopsy is an essential auditing tool in clinical practice. ObjectiveS: The study set out to review all autopsies that were performed over a four-year period in order to determine the rate, indications, as well as the age and sex distribution of dead bodies, which autopsies were performed on them in the Hospital. Setting and Design: This was a retrospective study that was undertaken at the department of Pathology of the University of Uyo Teaching Hospital (UUTH, Uyo, Nigeria between January 2007 and December 2010. Materials and Methods: All the cases of death that underwent pathological autopsies in the UUTH were reviewed. The autopsy records, clinical case notes, gross and histopathological specimens as well as slides were retrieved and examined. Results: A total of 1679 dead bodies were received at the mortuary of the institution studied during the 4-year period. Autopsies were performed in 78 cases giving a request rate of 4.7%. Coroner′s autopsy was commonly performed, and this accounted for 60 (76.9% cases, while the remaining 18 (23.1% were clinical autopsies. Autopsies were commonly performed on male bodies more than females (M: F = 2.6:1.0 with the majority having died at their second decade of life. It was observed that the majority (57.7% of the request for autopsies were from peripheral centers outside the teaching hospital, while the remaining 42.3% cases were drawn from various clinical departments in the teaching hospital. Road traffic accident was the leading indication for coroner′s autopsy (51.7%, while gastroenteritis and chronic liver disease were the two most common indications for clinical autopsy, 27.8% and 22.2% respectively. The concordance rate between clinical diagnosis and autopsy diagnosis was found to be 72.2% (13/18 cases. Conclusion: The rate of request for Autopsy at the University of Uyo Teaching Hospital during the period of this study was low, similar to other previous reports.

    1997-02-01

    Digital printing is described as a tool to replace conventional printing machines completely. Still this goal was not reached until now with any of the digital printing technologies to be described in the paper. Productivity and costs are still the main parameters and are not really solved until now. Quality in digital printing is no problem anymore. Definition of digital printing is to transfer digital datas directly on the paper surface. This step can be carried out directly or with the use of an intermediate image carrier. Keywords in digital printing are: computer- to-press; erasable image carrier; image carrier with memory. Digital printing is also the logical development of the new digital area as it is pointed out in Nicholas Negropotes book 'Being Digital' and also the answer to networking and Internet technologies. Creating images text and color in one country and publishing the datas in another country or continent is the main advantage. Printing on demand another big advantage and last but not least personalization the last big advantage. Costs and being able to coop with this new world of prepress technology is the biggest disadvantage. Therefore the very optimistic growth rates for the next few years are really nonexistent. The development of complete new markets is too slow and the replacing of old markets is too small.

    Neurocysticercosis (NCC) is a common central nervous system (CNS) infection caused by Taenia solium metacestodes. The objective of this study is to describe the incidence of cysticercosis diagnosed at autopsies and describe the epidemiological and clinical characteristics of NCC. Retrospective study analyzing 6,500 reports of autopsies between 1977 and 1994 from a school hospital in Curitiba, PR, southern of Brazil. The following data was obtained, age, gender, site of cysticercosis, NCC as cause of death. The diagnosis of cysticercosis was established in 52 (0.8%) autopsies. From 1977 to 1987 (0.7%) and from 1988 to 1994 (1.1%). In the autopsies with cysticercosis 75% were male; age (mean ± SD) was 43 ± 20. NCC was present in 96% of cases, and seizures was the most frequent clinical manifestation. Asymptomatic cases in 54%. These data classify our area as hiperendemic, according with OMS criteria. The present study reinforces the necessity to develop adequate control programs.

    Science.gov (United States)

    Tag, B

    2011-11-01

    Significant reasons militate for the implementation of clinical autopsies: On the part of physicians and nurses, there is quality assurance, establishment of legal certainty regarding possible accusations of medical errors and development of treatment methods. On the part of patients and their relatives, there is consolation and relief in cases of unexpected death, insight into genetic dispositions and insurance law concerns, to name only a few. However, a continuing decrease of clinical autopsies can be observed in Switzerland, Germany and Austria. The thesis asserting that the often required informed consent of the deceased during his/her lifetime or of close relatives is a crucial reason for this decrease needs to be called into question due to recent studies. Mainsprings are rather structural reasons, such as the often deficient communication with the patient or close relatives, economic reasons, namely the frequently insufficient remuneration for the clinical autopsy, organizational causes, in particular the repeatedly encountered suboptimal collaboration between the individual departments and the pathology department, the high administrative effort and probably the decreasing appreciation of the clinical autopsy.

They are consistent with the hypothesis that brain hypoperfusion contributes to dementia, possibly to AD pathogenesis, and raise the possibility that the APOE allele ε4 contributes directly to heart valve and myocardial damage.

    Full Text Available Involvement of the digestive system in patients with acquired immunodeficiency syndrome (AIDS is frequent and many changes in these patients are diagnosed only at autopsy. There are few studies of autopsy with detailed analysis of this system and only one was conducted in Brazil. We evaluated each segment of the digestive system in 93 consecutive autopsies of patients infected with human immunodeficiency virus (HIV and the importance of these lesions to death. Of these, 90 (96.8% patients had AIDS. We reviewed medical records, autopsy reports and histological sections from tongue to rectum stained with hematoxylin-eosin. When necessary, we analyzed special stains and immunohistochemistry to investigate infections. There was damage to the digestive system in 73 (78.5% cases. The most common infections were candidiasis (42%, cytomegalovirus (29%, histoplasmosis (11.8%, toxoplasmosis (9.7% and mycobacterial infection (9.7%. Malignancies were rare, present in four (4.3% cases (two Kaposi's sarcoma, one adenocarcinoma and one metastatic embryonal carcinoma. All segments showed lesions: tongue (48.6%, esophagus (44.8%, stomach (44.7%, colon (43.2% and small intestine (28.9%. The lesions found were immediate cause of death in five (5.4% cases. In another 36 (38.7% cases the basic disease was systemic and also compromised the digestive system.

    Full Text Available BACKGROUND Biological identity is one of the first things to be established when analysing skeletal, badly decomposed or otherwise unidentified human remains. The determination of age at death is an important component of identity establishment. Pubic symphysis examination is one of the reliable methods of age estimation. We attempt to determine the age of deceased from pubic symphysis using Suchey-Brooks method and to find the accuracy of Suchey-Brooks method in our population. From among the cases brought for autopsy at Department of Forensic Medicine, Government Medical College, Kottayam, Kerala, from 01/03/2012 to 28/02/2013, 316 cases were included in the study. Their pubic symphysis were harvested. Age determined using SucheyBrooks method and compared with their chronological age. The aim of the study is to- 1. Determine the age of deceased from pubic symphysis using Suchey-Brooks method. 2. Compare the age determined by Suchey-Brooks method and chronological age and find the accuracy of Suchey-Brooks method in our population. MATERIALS AND METHODS Study Design- Descriptive study- Cross-sectional study, Centre of Study- Department of Forensic Medicine, Government Medical College, Kottayam, Study Sample- From the cases brought for medicolegal postmortem examination in the Department of Forensic Medicine, Government Medical College, Kottayam, Kerala, a sample of 316 cases were selected. To make the distribution among various age groups, even the total sample divided for the age group, which resulted in having 60 samples per age group. Age groups were considered as Group 1- Age between 18-25 years; Group 2- Age between 25-35 years; Group 3- Age between 35-45 years; Group 4- Age between 45-55 years; Group 5- Age between 55-65 years. Inclusion Criteria- 1. Cases with known age; 2. Cases whose age between 18 and 65 years. Exclusion Criteria- 1. Unknown cases; 2. Known cases with doubtful age; 3.

    Full Text Available Context: Autopsy rates have declined all over the world recently. Clinical autopsy is considered to be an essential element for medical auditing and teaching and a useful tool for the evaluation of accuracy of the clinical diagnoses. Objetive: We describe the concordance between clinical diagnoses and autopsy findings in a tertiary care center. Materials and methods: We compared the diagnosis recorded on medical charts with reports of 100 autopsies performed between 1970 and 1975, and in 100 autopsies performed between 1990 and 1995 in the department of pathology of a terciary care hospital. The autopsy diagnoses were used as the “gold standard”. Results: The higher sensivity for diagnosis was observed for neoplasic disease in both period and for hemodinamics disorders, thrombosis and shock in 1970. The clinical diagnosis of the basic cause of death was confirmed at autopsy in 73% and 64% of cases in period 1970 and 1990 respectively. The percent confirmation fell when the immediate terminal cause of death was considered, and in 36.5% of cases, the terminal cause was only diagnosed at autopsy. Of 200 adults patients, 62 (31% had an infectious disease at autopsy. In 25 (40.3% of 62 patients, the infectious disease diagnoses were unknown clinically. There are substantial discrepancies between clinical and autopsy diagnoses of infectious disease. The bronchopneumonia is the infectious disease most often missed clinically (24.5% of the cases, similar in both periods. The discrepancies between clinical and autopsy diagnosis were even larger for secondary diagnoses: 63% of them were not suspected upon clinical diagnosis. The most frequently omitted diagnosis was bronchopneumonia. Iatrogenic injuries were very frequent, and approximately 28% of them were not described in clinical reports. Conclusions: Our results suggest that highly sensitive and specific diagnostic tests are necessary but cannot substitute the clinical practice for the elaboration

    Multislice-computed tomography (MSCT) and magnetic resonance imaging (MRI) are increasingly used for forensic purposes. Based on broad experience in clinical neuroimaging, post-mortem MSCT and MRI were performed in 57 forensic cases with the goal to evaluate the radiological methods concerning their usability for forensic head and brain examination. An experienced clinical radiologist evaluated the imaging data. The results were compared to the autopsy findings that served as the gold standard with regard to common forensic neurotrauma findings such as skull fractures, soft tissue lesions of the scalp, various forms of intracranial hemorrhage or signs of increased brain pressure. The sensitivity of the imaging methods ranged from 100% (e.g., heat-induced alterations, intracranial gas) to zero (e.g., mediobasal impression marks as a sign of increased brain pressure, plaques jaunes). The agreement between MRI and CT was 69%. The radiological methods prevalently failed in the detection of lesions smaller than 3mm of size, whereas they were generally satisfactory concerning the evaluation of intracranial hemorrhage. Due to its advanced 2D and 3D post-processing possibilities, CT in particular possessed certain advantages in comparison with autopsy with regard to forensic reconstruction. MRI showed forensically relevant findings not seen during autopsy in several cases. The partly limited sensitivity of imaging that was observed in this retrospective study was based on several factors: besides general technical limitations it became apparent that clinical radiologists require a sound basic forensic background in order to detect specific signs. Focused teaching sessions will be essential to improve the outcome in future examinations. On the other hand, the autopsy protocols should be further standardized to allow an exact comparison of imaging and autopsy data. In consideration of these facts, MRI and CT have the power to play an important role in future forensic

  9. An autopsy case of minamata disease (methylmercury poisoning)--pathological viewpoints of peripheral nerves.

    2002-01-01

    The outbreak of methylmercury poisoning in the geographic areas around Minamata Bay, Kumamoto, Japan in the 1950s has become known as Minamata disease. Based on earlier reports and extensive pathological studies on autopsied cases at the Kumamoto University School of Medicine, destructive lesions in the anterior portion of the calcarine cortex and depletion predominantly of granular cells in the cerebellar cortex came to be recognized as the hallmark and diagnostic yardstick of methylmercury poisoning in humans. As the number of autopsy cases of Minamata disease increased, it became apparent that the cerebral lesion was not restricted to the calcarine cortex but was relatively widespread. Less severe lesions, believed to be responsible for the motor symptoms of Minamata patients, were often found in the precentral, postcentral, and lateral temporal cortices. These patients also frequently presented with signs of sensory neuropathy affecting the distal extremities. Because of few sufficiently comprehensive studies, peripheral nerve degeneration has not been universally accepted as a cause of the sensory disturbances in Minamata patients. The present paper describes both biopsy and autopsy findings of the peripheral nerves in a male fisherman who died at the age of 64 years and showed the characteristic central nervous system lesions of Minamata disease at autopsy. A sural nerve biopsy with electron microscopy performed 1 month prior to his death showed endoneurial fibrosis and regenerated myelin sheaths. At autopsy the dorsal roots and sural nerve showed endoneurial fibrosis, loss of nerve fibers, and presence of Büngner's bands. The spinal cord showed Wallerian degeneration of the fasciculus gracilis (Goll's tract) with relative preservation of neurons in sensory ganglia. These findings support the contention that there is peripheral nerve degeneration in Minamata patients due to toxic injury from methylmercury.

    To develop profile of the victims and to study circumstances, causes of death and autopsy findings. Retrospective study of cases of sudden death in sport activity whose autopsy was performed in forensic department of Tunis, between January 2005 and December 2009. During study period, 32 cases of SD in sport activity were recorded. These are amateur athletes predominantly male (84% of cases). Victims are aged between 15 and 79 years with an average age of about 33.16 years. Young subjects whose age is less than 35 years representing 68.7% of cases. 9.3% of victims had a family history of SD and 18.7% of cases had a known cardiac history. The sports most involved are running (40.6% of cases), football (31.3% of cases) and dance (12.5% of cases). Sixty-nine percent of victims died during sports activities. Presence of witnesses was noted in all cases; however, none of these witnesses has begun resuscitation. Cause of death was cardiac in 84.4% of cases. In young athletes, hypertrophic cardiomyopathy is the leading cause (nine cases), followed by arrhythmogenic right ventricular dysplasia (three cases). Among other causes, there is the myocardial bridge, congenital anomalies of the coronary arteries, aortic dissection and dilated cardiomyopathy. Beyond 35 years, coronary artery diseases represent the cause of death (nine cases). Only case of death secondary to non-cardiac disease occurred after a severe asthma attack. In four cases (12.5%), no cause of death was identified after a complete autopsy accompanied by further investigations. The cause of the death was imputed to a rhythmic pathology. This is the first study dealing with autopsy in SD in sport have provided a specific profile of victims. Other studies on larger samples and using standardized autopsy protocols are needed.

    Full Text Available Abstract Background Because of a physician shortage in many low-income countries, the use of nonphysicians to classify perinatal mortality (stillbirth and early neonatal death using verbal autopsy could be useful. Objective To determine the extent to which underlying perinatal causes of deaths assigned by nonphysicians in Guatemala, Pakistan, Zambia, and the Democratic Republic of the Congo using a verbal autopsy method are concordant with underlying perinatal cause of death assigned by physician panels. Methods Using a train-the-trainer model, 13 physicians and 40 nonphysicians were trained to determine cause of death using a standardized verbal autopsy training program. Subsequently, panels of two physicians and individual nonphysicians from this trained cohort independently reviewed verbal autopsy data from a sample of 118 early neonatal deaths and 134 stillbirths. With the cause of death assigned by the physician panel as the reference standard, sensitivity, specificity, positive and negative predictive values, and cause-specific mortality fractions were calculated to assess nonphysicians' coding responses. Robustness criteria to assess how well nonphysicians performed were used. Results Causes of early neonatal death and stillbirth assigned by nonphysicians were concordant with physician-assigned causes 47% and 57% of the time, respectively. Tetanus filled robustness criteria for early neonatal death, and cord prolapse filled robustness criteria for stillbirth. Conclusions There are significant differences in underlying cause of death as determined by physicians and nonphysicians even when they receive similar training in cause of death determination. Currently, it does not appear that nonphysicians can be used reliably to assign underlying cause of perinatal death using verbal autopsy.

    Verbal autopsies have gained considerable ground as an acceptable alternative to medically determined cause of death. Unlike with clinical or more administrative settings for data collection, verbal autopsies require significant involvement of families and communities, which introduces important social and cultural considerations. However, there is very little clear guidance about the methodological issues in data collection. The objectives of this case study were: to explore the range of bereavement rituals within the multi-ethnic, multi-faith population of the district; to investigate the preparedness of communities to talk about death; to describe the verbal autopsy process; to assess the effects of collecting verbal autopsy data on data collectors; and to determine the most accurate sources of information about deaths in the community. A case study approach was used, using focus group discussions, indepth interviews and field notes. Thematic analyses were undertaken using NVivo. Consideration of cultural bereavement practices is importance to acceptance and response rates to verbal autopsies. They are also important to the timing of verbal autopsy interviews. Well trained data collectors, regardless of health qualifications are able to collect good quality data, but debriefing is important to their health and well being. This article contributes to guidance on the data collection procedures for verbal autopsies within community settings.

    1995-10-01

    The purpose of this investigation is to estimate the prevalence of acute pulmonary embolism (PE) in a general hospital, its frequency among patients who died, and the ability of physicians to diagnose PE antemortem. The prevalence of acute PE among 51,645 patients hospitalized over a 21-month period was assessed in 1 of the 6 clinical centers (Henry Ford Hospital) that participated in the collaborative study, prospective investigation of pulmonary embolism diagnosis (PIOPED). The diagnosis of PE was made by pulmonary angiography, or in those who did not undergo pulmonary angiography because they declined or were ineligible for randomization to angiography in PIOPED, the diagnosis was based on the ventilation/perfusion (V/Q) lung scan. Based on data in PIOPED, PE was considered to be present in 87% of patients with high probability V/Q scam interpretations, 30% with intermediate probability interpretations, 14% with low probability interpretations, and 4% with nearly normal V/Q scans. The estimated prevalence of acute PE in hospitalized patients was 526 of 51,645 (1.0%; 95% confidence interval [CI], 0.9 to 1.1%). Based on extrapolated data from autopsy, PE was estimated to have caused or contributed to death in 122 of 51,645 (0.2%; 95% CI, 0.19 to 0.29%). Pulmonary embolism was observed at autopsy in 59 of 404 (14.6%; 95% CI, 11.3 to 18.4%). Among patients with PE at autopsy, the PE caused or contributed to death in 22 of 59 (37.3%; 95% CI, 25.0 to 50.9%) and PE was incidental in 37 of 59 (62.7%; 95% CI, 49.1 to 75.0%). Among patients at autopsy who died from PE, the diagnosis was unsuspected in 14 of 20 (70.0%; 95% CI, 45.7 to 88.1%). Most of these patients had advanced associated disease. In these patients, death from PE occurred within 2.5 h in 13 of 14 (92.9%; 95% CI, 66.1 to 99.8%). Pulmonary embolism is common in a general hospital. The prevalence of PE at autopsy has not changed over 3 decades. The frequency of unsuspected PE in patients at autopsy has not

    2009-01-01

    Factors and stressful life situations associated with suicidal hanging in a sample from India were studied with a view to explore preventability. Information was collected on consecutive suicidal hanging victims in a 2-year period from various sources including family members through psychological autopsy method. Out of 662 autopsies involving suicide during the study period, 104 had used hanging as the method. Age group of 21-30 years, married females, unmarried males, dowry related stress, unemployment, prolonged illness, failure in examinations, relationship and financial problems were associated more frequently with suicidal hanging. Stresses stemming from social practices and perceptions are linked with considerable number of suicidal hanging, which suggest priority areas for intervention.

    Full Text Available Myocardial abscess is a severe and life-threatening infectious complication thatis commonly but not exclusively associated with infective endocarditis. It mayalso be developed in necrotic myocardial tissue, post trauma, in septic burnpatients, in transplanted heart, in ventricular aneurysm and post angioplasty.Patients on hemodialysis are prone to bacteremia, and infectious complicationsoccur in 48-73% of cases. Myocardial abscess is a rare complication of aninfected arteriovenous fistula. We present an autopsy report of a hemodialysispatient who had an arteriovenous fistula with a polytetrafluoroethylene graftwhere a local infection developed. The patient presented with fever and toxemia.On post-admission day 2, he unexpectedly suffered sudden cardiopulmonaryarrest and died. The autopsy revealed a myocardial abscess, near a branch ofthe left coronary artery, with septic embolism.

    Autopsy detected no tumor tissues in a patient who died 6.5 years after the diagnosis of glioblastoma multiforme. A 54-year-old male developed left hemiparesis one month prior to admission. Computed tomography demonstrated a cystic lesion in the right frontal region with irregular ring-like enhancement. The tumor was extensively removed together with the surrounding tissues followed by irradiation (whole brain 32.4 Gy, local 28.8 Gy), and intravenous administration of interferon-{beta}. Histological examination confirmed the diagnosis of glioblastoma multiform. He died of accidental head trauma 6.5 years after surgery. Autopsy of the brain detected no evidence of glioblastoma multiform. The only findings were cerebral edema and hematoma caused by head trauma, as well as histological changes due to radiation damage. This case apparently confirms the histological disappearance of tumor tissue in a long-term survivor with glioblastoma multiform. (author)

    The autopsy case of a 3-year 6-month-old boy with chordoma arising in the sacrococcygeal region is presented. The primary lesion of the sacrococcygeal area was unresectable and lung metastasis was detected. He was treated with multi-agent systemic chemotherapy and radiation therapy, but the tumor was less responsive to these therapies. He died about one year after first admission. An autopsy revealed a massive sacrococcygeal mass and metastasis in the thoracic and lumbar vertebrae, retroperitoneal and mediastinal lymph nodes, and also in the bilateral lungs and liver. Histologically, the tumor was composed of 'pink' cells and scattered 'physaliphorous' cells with a myxoid matrix. Sacrococcygeal chordoma in infancy is very rare. Our case showed a highly aggressive clinical course.

    Full Text Available Background: Renal papillary adenoma is usually an incidental finding at autopsy with an incidence of 7% to 23%. The frequency of small papillary tumours of kidney increases with age to approximately 40% of the population over the age of 65. These tumours occur morefrequently in scarred kidneys, acquired renal cystic disease and in children with von Hippel-Lindau syndrome. Case history: In this report we describe renal papillary adenoma incidentally detected during autopsies of two elderly males. Gross examination of kidneyshowed two tiny subcapsular yellowish nodules in one case and single nodule with similar morphology in the other. Microscopic examination in both the cases showed a well circumscribed tumour composed of densely packed tubules and papillae lined by small cuboidal to columnar cells with rounded uniform nuclei. However there was no nuclear atypia, mitosis or necrosis.

    Motor vehicle accidents contribute widely to population morbidity and mortality around the world, and cardiac injuries are a major factor determining outcome. Autopsy reports from 380 motor vehicle occupants who died in motor vehicle crashes in Adelaide, Australia, and Hamburg, Germany, over a 6-year period were reviewed, analysing the presence and type of cardiac injuries and their correlation with factors such as crash type, presence of seatbelt/airbag and vehicle speed as well as with the presence of other injuries which might predict the presence of cardiac injuries in a clinical setting. 21.1% had cardiac injuries identified macroscopically autopsy or histology. Cardiac injuries were the only cause of death or contributed to a fatal outcome in 76% of these cases. Sternal fractures and left-sided serial rib fractures were predictive of cardiac injury.

    A 19-year-old woman was found dead with her face and head wrapped in plastic adhesive tape in a cupboard beside an opened helium cylinder. Despite the alleged presence of a suicide message on a social networking website, the unusual circumstances raised the possibility at the time of autopsy of either accidental death from sexual asphyxia or homicide. A carefully monitored reenactment demonstrated, however, that the type of commercial adhesive tape that had been used did not cause complete airway obstruction and that it was possible to wrap a considerable length of tape around the head and neck with the breath held. All of the features at autopsy were, therefore, compatible with self-infliction. Asphyxial death was attributed to the combined effects of smothering from tape and anoxia from helium, an extremely rare combination in young females.

    Full Text Available Aberrant transplacental arteriovenous shunts between the placental and cord vessels of monozygotic monoamniotic twins or triplets result in the formation of an acardius. The prenatal diagnosis of this condition has been reported occasionally in the literature. A subtype categorized as acardius myelancephalus was diagnosed at 32 weeks of gestation by ultrasonography (USG. The pregnancy was aborted because of poor prognostic predictors and the acardius was subjected to ultrasonographic autopsy (fetal echopsy. The antenatal USG features were correlated with echopsy findings for confirmation of the antenatal findings and for a better visual perception of the prenatal diagnostic features. The echopsy revealed more precise details. Fetal echopsy avoids the medicolegal problems concerned with parental consent for classical invasive fetal autopsy.

    Full Text Available The mesolimbic dopamine (DA system has been associated with the pathogenesis of schizophrenia. Here, we examined DA-containing neuronal structures of the ventral tegmental area (VTA of an autopsy case of disorganized type of schizophrenia (75-year-old female, using tyrosine hydroxylase (TH immunohistochemistry. A free floating method using 50-μm cryostat sections and three-dimensional imaging analyzer AxioVision were applied to observe the wide range structures of TH-immunoreactive (-ir neurons. TH-ir neuronal cell bodies in the VTA of the present case had irregular shape and various size, and TH-ir neuronal processes had irregular thickness and straightened shape or curved shape having many corners, when compared to a control autopsy case with no detectable neurological and psychiatric diseases (64-year-old male. The mechanisms underlying the morphological characteristics of DA neurons of the brains with schizophrenia should be elucidated epigenetically as well as genetically.

    Full Text Available Rhodotorula species have been reported as a causative agent of opportunistic mycoses in immunocompromised hosts. We report a case of sepsis and meningoencephalitis caused by Rhodotorula glutinis in a 20-year-old female patient with systemic lupus erythematosus (SLE, which was diagnosed at autopsy. The patient presented with longstanding fever. She was diagnosed with SLE after admission to the hospital and died on day 5 of the hospital stay. Autopsy was performed to confirm the presence of infection. Sepsis and meningoencephalitis due to Rhodotorula glutinis was confirmed by postmortem blood cultures and histopathological examination of biopsies taken from the brain at autopsy. Infection by Rhodotorula spp. is rare but can be fatal in immunocompromised hosts. Infections by such uncommon yeasts may often be difficult to diagnose, especially in the setting of febrile neutropenia. This report also emphasizes the value of autopsy as a powerful educational tool.

    Objective: To conduct a validation study of 123I-N-fluoropropyl-2b-carbomethoxy-3b-(4-iodophenyl) nortropane (123I-FP-CIT) SPECT dopaminergic imaging in the clinical diagnosis of dementia with Lewy bodies (DLB) with autopsy as the gold standard. Methods: Patients >60 years of age with dementia who had undergone 123I-FP-CIT imaging in research studies and who had donated their brain tissue to the Newcastle Brain Tissue Resource were included. All had structured clinical research assessments, and clinical diagnoses were applied by consensus panels using international diagnostic criteria. All underwent 123I-FP-CIT imaging at baseline, and scans were rated as normal or abnormal by blinded raters. Patients were reviewed in prospective studies and after death underwent detailed autopsy assessment, and neuropathologic diagnoses were applied with the use of standard international criteria. Results: Fifty-five patients (33 with DLB and 22 with Alzheimer disease) were included. Against autopsy diagnosis, 123I-FP-CIT had a balanced diagnostic accuracy of 86% (sensitivity 80%, specificity 92%) compared with clinical diagnosis, which had an accuracy of 79% (sensitivity 87%, specificity 72%). Among patients with DLB, 10% (3 patients) met pathologic criteria for Lewy body disease but had normal 123I-FP-CIT imaging. Conclusions: This large autopsy analysis of 123I-FP-CIT imaging in dementia demonstrates that it is a valid and accurate biomarker for DLB, and the high specificity compared with clinical diagnosis (20% higher) is clinically important. The results need to be replicated with patients recruited from a wider range of settings, including movement disorder clinics and general practice. While an abnormal 123I-FP-CIT scan strongly supports Lewy body disease, a normal scan does not exclude DLB with minimal brainstem involvement. Classification of evidence: This study provides Class I evidence that 123I-FP-CIT dopaminergic neuroimaging accurately identifies patients with DLB

    Full Text Available Background/Aim. Drug abuse remains a significant social problem in many countries. The aim of the study was to estimate association between pulmonary histopathological changes and results of toxicological analyses in forensic autopsies of illicit drug users. Methods. This investigation was performed in the Institute of Forensic Medicine, Belgrade, and in the Clinical Center, Department of Forensic Medicine, Kragujevac, from 2000 to 2004, and included 63 medicolegal autopsies of heroin or other drug consumers who suddenly died. Autopsies, postmortem toxicological examination of drugs and serological analyses of anti- HIV/HBV/HCV antibodies were performed. Results. The deceased persons were mostly male, 46/63 (73.01%, ranged in age from 19 to 49 years (mean 31 years and all were whites. Postmortem toxicological examination was performed on all of the deceased persons and drugs in the fatal range were identified in only eight of them (12.7%, in the toxic range in ten (15.87%, and in minimal concentrations in 35 (55.56% of the deceased persons. Drugs identified in the fatal, toxic or minimal range included heroin-morphine (38/53, cocaine (4/53, tramadol (3/53, and lorazepam (1/53. In the 7 remaining subjects, ethanol in combination with heroin was found in 4 cases, and diazepam in combination with heroin in 3 cases. Dominant pathomorphological changes were findings in the lung tissue. Most common histological changes observed in drug users were pulmonary edema - 55/63 (87.3%, acute alveolar hemorrhages - 49/63 (77.78%, hemosiderin-laden macrophages (siderophages - 52/63 (82,54%, and emphysematous changes - 51/63 (80,95%. Conclusion. Pulmonary edema is the frequent non-specific autopsy finding which is associated with virtually all routes of drug administration. The histopatological study is necessary to determinate a cause of death when a deceased person has the history of dependence or abouse of psychoactive drugs with negative toxicological

  5. Measuring Maternal Mortality: Three Case Studies Using Verbal Autopsy with Different Platforms.

    Directory of Open Access Journals (Sweden)

    Siân L Curtis

    Full Text Available Accurate measurement of maternal mortality is needed to develop a greater understanding of the scale of the problem, to increase effectiveness of program planning and targeting, and to track progress. In the absence of good quality vital statistics, interim methods are used to measure maternal mortality. The purpose of this study is to document experience with three community-based interim methods that measure maternal mortality using verbal autopsy.This study uses a post-census mortality survey, a sample vital registration with verbal autopsy, and a large-scale household survey to summarize the measures of maternal mortality obtained from these three platforms, compares and contrasts the different methodologies employed, and evaluates strengths and weaknesses of each approach. Included is also a discussion of issues related to death identification and classification, estimating maternal mortality ratios and rates, sample sizes and periodicity of estimates, data quality, and cost.The sample sizes vary considerably between the three data sources and the number of maternal deaths identified through each platform was small. The proportion of deaths to women of reproductive age that are maternal deaths ranged from 8.8% to 17.3%. The maternal mortality rate was estimable using two of the platforms while obtaining an estimate of the maternal mortality ratio was only possible using one of the platforms. The percentage of maternal deaths due to direct obstetric causes ranged from 45.2% to 80.4%.This study documents experiences applying standard verbal autopsy methods to estimate maternal mortality and confirms that verbal autopsy is a feasible method for collecting maternal mortality data. None of these interim methods are likely to be suitable for detecting short term changes in mortality due to prohibitive sample size requirements, and thus, comprehensive and continuous civil registration systems to provide high quality vital statistics are essential

    Full Text Available BACKGROUND: Pneumonia remains the number one killer of children, taking the lives of 1.3 million in 2011 alone. More than 99% of all pneumonia deaths occur in developing countries. The majority of pneumonia cases are preventable and treatable, but clinical diagnosis is highly fallible in many cases and the frequency of morbid state is best assessed by post-mortem examination that may reveal diagnosis which may not be suspected clinically or may, in some way, discredit. AIMS: 1. To ascertain various pulmonary lesions in paediatric deaths. 2. To find incidence of pulmonary lesions. 3. To study the incidence of pulmonary tuberculosis, 4. To find incidence of pulmonary pathology directly and indirectly contributing to the death. SETTINGS: Lokmanya Tilak Municipal General Hospital, Sion, Mumbai. DESIGN: A retrospective observational study. METHODS AND MATERIAL: In this study pediatric age group of (0-15 years admitted in IPCU,NICU and Pediatric, Medicine and Surgery unit are included from the period of 2006-2013. The lung pathology in various diseases entities were studied and co-related with age, sex and clinical history. RESULTS: Of total 3606 autopsies, 642 were pediatric autopsies i.e. 17.8% of all autopsies, and 111 were neonatal autopsies. Of 642, 531(82.7% had primary lung pathology and 157(24.4% had secondary lung pathology. The common age group affected is < 5 years. Bronchopneumonia was the commonest pathology observed as primary lung pathology. Interstitial/viral pneumonia was 2nd most common of primary lung pathology Infective pathology was the most common lesions, of which bronchopneumonia was the most common pathology observed and tuberculosis contributed to 3%of primary lung pathologies. CONCLUSION: The most common lung lesion in pediatric age is infections, which are preventable and curative with appropriate measures. This study will help to improve mother child health services

    Full Text Available Abstract Background Traditional multiplexed gene expression methods require well preserved, intact RNA. Such specimens are difficult to acquire in clinical practice where formalin fixation is the standard procedure for processing tissue. Even when special handling methods are used to obtain frozen tissue, there may be RNA degradation; for example autopsy samples where degradation occurs both pre-mortem and during the interval between death and cryopreservation. Although specimens with partially degraded RNA can be analyzed by qRT-PCR, these analyses can only be done individually or at low levels of multiplexing and are laborious and expensive to run for large numbers of RNA targets. Methods We evaluated the ability of the cDNA-mediated Annealing, Selection, extension, and Ligation (DASL assay to provide highly multiplexed analyses of cryopreserved and formalin fixed, paraffin embedded (FFPE tissues obtained at autopsy. Each assay provides data on 1536 targets, and can be performed on specimens with RNA fragments as small as 60 bp. Results The DASL performed accurately and consistently with cryopreserved RNA obtained at autopsy as well as with RNA extracted from formalin-fixed paraffin embedded tissue that had a cryopreserved mirror image specimen with high quality RNA. In FFPE tissue where the cryopreserved mirror image specimen was of low quality the assay performed reproducibly on some but not all specimens. Conclusion The DASL assay provides reproducible results from cryopreserved specimens and many FFPE specimens obtained at autopsy. Gene expression analyses of these specimens may be especially valuable for the study of non-cancer endpoints, where surgical specimens are rarely available.

  8. Single umbilical artery and associated malformations in over 5500 autopsies: relevance for perinatal management.

    With a birth prevalence rate of about 1%, single umbilical artery (SUA) is the most frequent of all congenital anomalies. It is recognizably associated with a variety of birth defects, but disagreement exists as to whether a SUA can predict an adverse perinatal outcome; disagreement also exists related to if, when present, other birth defects should be ruled out. The aims of the study were to estimate the association between SUA and other birth defects in a series of perinatal autopsies, to establish if preferential associations between SUA and certain birth defects exist, and to quantify the risks for other birth defects when a SUA is diagnosed. In a series of 5539 perinatal autopsies conducted at the Hospital Materno Infantil Ramón Sardá and the Private Laboratory of Perinatal Pathology, Buenos Aires, Argentina, the rate of each malformation (grouped by organ/system) associated with SUA and the risks of associated malformations were estimated. In this series of autopsies, the rate of SUA showed a 10-fold increase when other malformations were present. The risk for other malformations increased significantly, by a 3-fold to 9-fold measure, when a SUA was present. Urinary and gut anomalies showed a preferential association with SUA. The absence of other birth defects lowered the risk of chromosome anomalies associated with SUA in 56% (odds ratio  =  0.44). These results, obtained from a series of perinatal autopsies, are in agreement with most observations found in the literature, namely, high association rates between SUA and urinary and cardiovascular anomalies as well as a low risk for chromosome anomalies in SUA cases without other malformations.

    Death resulting from burns is an important social problem and a frequent accident. However, because approximately 10% of cases are estimated to result from a fire that was deliberately started, all fire-related deaths should be treated as suspicious, and the cause of a fire should be investigated. For the bodies recovered from the scene of a fire, the manner of death could also be suicide or homicide. The objective of this study was to contribute to the clarification of controversial data present in the literature on the manner of death determination of fire-related deaths, through evaluation of autopsy findings of bodies recovered from fires. We reviewed 20,135 autopsies performed in a 5-year period, in Istanbul, as the whole autopsy data of the city and found 133 fire-related deaths. The death scene investigation reports and other judicial documents, autopsy findings, and toxicological analysis results were evaluated to determine the parameters of age, sex, level of the burn, vital signs [red flare; soot in the lower respiratory tract, esophagus, and/or stomach; and screening of carboxyhemoglobin (COHb) levels in the blood], toxicological substances, presence of accelerants, cause of death, and manner of death. The manner of death was determined to be an accident in 98 (73.7%) and homicide in 12 (9%) cases, whereas there was no suicide. In addition, it could not be determined in 23 (17.2%) cases. In accidental deaths, the most frequent cause of death was COHb poisoning with statistically significant blood COHb levels greater than 10%. Further, the presence of soot in the lower respiratory tract, esophagus, and/or stomach and the existence of at least 1 or 2 vital signs together were found to be valid deterministic criteria with statistical significance in terms of identifying the manner of death.

    Full Text Available BACKGROUND: Vital registration and cause of death reporting is incomplete in the countries in which the HIV epidemic is most severe. A reliable tool that is independent of HIV status is needed for measuring the frequency of AIDS deaths and ultimately the impact of antiretroviral therapy on mortality. METHODS AND FINDINGS: A verbal autopsy questionnaire was administered to caregivers of 381 adults of known HIV status who died between 1998 and 2003 in Manicaland, eastern Zimbabwe. Individuals who were HIV positive and did not die in an accident or during childbirth (74%; n = 282 were considered to have died of AIDS in the gold standard. Verbal autopsies were randomly allocated to a training dataset (n = 279 to generate classification criteria or a test dataset (n = 102 to verify criteria. A rule-based algorithm created to minimise false positives had a specificity of 66% and a sensitivity of 76%. Eight predictors (weight loss, wasting, jaundice, herpes zoster, presence of abscesses or sores, oral candidiasis, acute respiratory tract infections, and vaginal tumours were included in the algorithm. In the test dataset of verbal autopsies, 69% of deaths were correctly classified as AIDS/non-AIDS, and it was not necessary to invoke a differential diagnosis of tuberculosis. Presence of any one of these criteria gave a post-test probability of AIDS death of 0.84. CONCLUSIONS: Analysis of verbal autopsy data in this rural Zimbabwean population revealed a distinct pattern of signs and symptoms associated with AIDS mortality. Using these signs and symptoms, demographic surveillance data on AIDS deaths may allow for the estimation of AIDS mortality and even HIV prevalence.

    Mucopolysaccharidosis IVA (MPS IVA; Morquio A syndrome) is a lysosomal storage disorder caused by deficiency of N-acetylgalactosamine-6-sulfate sulfatase, which results in systemic accumulation of glycosaminoglycans (GAGs), keratan sulfate and chondroitin-6-sulfate. Accumulation of these GAGs causes characteristic features as disproportionate dwarfism associated with skeletal deformities, genu valgum, pigeon chest, joint laxity, and kyphoscoliosis. However, the pathological mechanism of systemic skeletal dysplasia and involvement of other tissues remain unanswered in the paucity of availability of an autopsied case and successive systemic analyses of multiple tissues. We report here a 20-year-old male autopsied case with MPS IVA, who developed characteristic skeletal features by the age of 1.5 years and died of acute respiratory distress syndrome five days later after occipito-C1-C2 cervical fusion. We pathohistologically analyzed postmortem tissues including trachea, lung, thyroid, humerus, aorta, heart, liver, spleen, kidney, testes, bone marrow, and lumbar vertebrae. The postmortem tissues relevant with clinical findings demonstrated 1) systemic storage materials in multiple tissues beyond cartilage, 2) severely vacuolated and ballooned chondrocytes in trachea, humerus, vertebrae, and thyroid cartilage with disorganized extracellular matrix and poor ossification, 3) appearance of foam cells and macrophages in lung, aorta, heart valves, heart muscle, trachea, visceral organs, and bone marrow, and 4) storage of chondrotin-6-sulfate in aorta. This is the first autopsied case with MPS IVA whose multiple tissues have been analyzed pathohistologically and these pathological findings should provide a new insight into pathogenesis of MPS IVA.

    Autopsies are performed in the majority of Arab, Muslim countries. Several of these countries face social challenges and others do not have well established academic programs to teach the science. In this article we intend to review the history and practice of the forensic part of autopsies in a few Arab, Muslim countries (Egypt, Kingdom of Saudi Arabia (KSA) and Kuwait) and compare it with the United States of America (USA) and the United Kingdom (UK), 2 countries where the practice of forensic science and Forensic pathology is well established. This was achieved by pub med literature search and the distribution of a questionnaire to colleagues in Arab countries. We recommend that Arab countries explore the field of virtual autopsy to overcome some of the social challenges related to dissection of the cadaver. Kuwait can benefit from the introduction of Forensic training given the high workload in the country. Copyright © 2015 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

    While electrolyte measurements after death may be confounded by a number of variables, vitreous humor sodium tends to remain stable for some time, enabling correlation between ante- and postmortem levels. Review of natural and unnatural causes of reduced vitreous humor sodium levels at autopsy was undertaken to demonstrate the range of diseases that may result in this finding. Natural diseases affecting the vasopressin-renin-angiotensin axis may cause reduction in sodium levels with associated hypovolemia, euvolemia, and hypervolemia. Low sodium measurements may also occur with redistribution of water, and artefactually when there are underlying lipid and protein disorders. Unnatural causes of hyponatremia at autopsy include water intoxication from psychogenic polydipsia, environmental polydipsia, ingestion of dilute infant formulas, beer potomania, endurance exercise, fresh water immersion (including water births) and iatrogenic causes including drug and parenteral fluid administration, and surgical irrigation. A knowledge of the range of conditions that may result in lowered postmortem sodium levels will help to exclude or confirm certain diseases at autopsy. In addition, significant vitreous hyponatremia may be a useful finding to help clarify mechanisms of unnatural deaths.

    The excessive release of inflammatory cytokines occasionally induces life-threatening hemophagocytosis referred to as hemophagocytic syndrome (HPS). A similar condition, histiocytic hyperplasia with hemophagocytosis (HHH), is often seen in bone marrow collected during autopsy. Unlike HPS, the pathogenesis of HHH remains unclear. Therefore, we performed a clinicopathological analysis of HHH from 70 autopsy cases at the University of Fukui Hospital. HHH was detected in 29 of 70 autopsies (41.4 %) and was significantly complicated with hematological diseases (p HHH (p HHH patients as compared with non-HHH patients. Concentrations of inflammatory mediators including IL-1β, IL-6, and IL-8 were significantly increased in HHH patients. Multivariate risk factor analysis identified hematological diseases (odds ratio (OR), 11.71), ≥ 15 % BM macrophages (OR, 9.42), sepsis (OR, 7.77), and high serum IL-6 levels (OR, 1.00) as independent risk factors for HHH. HHH with hypocellular BM, the most aggressive form of HHH, was recognized in 8 of 29 HHH patients and was associated with ≥ 25 % BM macrophages (p HHH patients fulfilled the diagnostic criteria of HPS. These findings suggest that HHH is a different entity from HPS and that it preferentially develops under conditions of excessive inflammation and its associated risks, such as hematological diseases and sepsis.

    Full Text Available The huge amount of multimedia contents available on the World-Wide-Web is beginning to raise the question of their protection. Digital watermarking is a technique which can serve various purposes, including intellectual property protection, authentication and integrity verification, as well as visible or invisible content labelling of multimedia content. Due to the diversity of digital watermarking applicability, there are many different techniques, which can be categorised according to different criteria. A digital watermark can be categorised as visible or invisible and as robust or fragile. In contrast to the visible watermark where a visible pattern or image is embedded into the original image, the invisible watermark does not change the visual appearance of the image. The existence of such a watermark can be determined only through a watermark ex¬traction or detection algorithm. The robust watermark is used for copyright protection, while the fragile watermark is designed for authentication and integrity verification of multimedia content. A watermark must be detectable or extractable to be useful. In some watermarking schemes, a watermark can be extracted in its exact form, in other cases, we can detect only whether a specific given watermarking signal is present in an image. Digital libraries, through which cultural institutions will make multimedia contents available, should support a wide range of service models for intellectual property protection, where digital watermarking may play an important role.

    Photogrammetry is the use of photography for surveying primarily and is used for the production of maps from aerial photographs. Along with remote sensing, it represents the primary means of generating data for Geographic Information Systems (GIS). As technology develops, it is becoming easier to gain access to it. The cost of digital photogrammetric workstations are falling quickly and these new tools are therefore becoming accessible to more and more users. Digital Photogrammetry is particularly useful as a text for graduate students in geomantic and is also suitable for people with a good basic scientific knowledge who need to understand photogrammetry, and who wish to use the book as a reference.

    The 19,094 autopsy examinations carried out between 1976-1990 revealed 698 (3.65%) case of cirrhosis, of which 64.6% were men. During the last 5 years the percentage of coexistance of hepatoma (hepatocellular carcinoma) with cirrhosis was higher 5-year periods (5.8%; 5.4%). Moreover, the same changing interrelation was observed for other malignancies and cirrhosis-higher (15%) in the last period than in the proceeding years (11.1%; 11.3%). The severity of atherosclerotic changes and coexistance of peptic ulcers, gall bladder disease and productive pulmonary tuberculosis in cirrhotic patients were also assessed. Finally the direct causes of these patients' death were discussed.

    The energy density in conventional capacitors is limited by sparking. We present nano-capacitor arrays, where - like in laser diodes and quantum wells [1] - quantization prevents dielectric breakthrough. We show that the energy density and the power/weight ratio are very high, possibly larger than in hydrogen [2]. Digital batteries are a potential clean energy source for cars, laptops, and mobile devices. The technology is related to flash drives. However, because of the high energy density, safety is a concern. Digital batteries can be easily and safely charged and discharged. In the discharged state they pose no danger. Even if a charged digital battery were to explode, it would produce no radioactive waste, no long-term radiation, and probably could be designed to produce no noxious chemicals. We discuss methodologies to prevent shorts and other measures to make digital batteries safe. [1] H. Higuraskh, A. Toriumi, F. Yamaguchi, K. Kawamura, A. Hubler, Correlation Tunnel Device, U. S.

    Diffuse intrinsic pontine glioma (DIPG) is a fatal paediatric malignancy. Tumour resection is not possible without serious morbidity and biopsies are rarely performed. The resulting lack of primary DIPG material has made preclinical research practically impossible and has hindered the development of new therapies for this disease. The aim of the current study was to address the lack of primary DIPG material and preclinical models by developing a multi-institutional autopsy protocol. An autopsy protocol was implemented in the Netherlands to obtain tumour material within a brief post mortem interval. A team of neuropathologists and researchers was available at any time to perform the autopsy and process the material harvested. Whole brain autopsy was performed and primary DIPG material and healthy tissue were collected from all affected brain areas. Finally, the study included systematic evaluation by parents. Five autopsies were performed. The mean time interval between death and time of autopsy was 3 h (range 2-4). All tumours were graded as glioblastoma. None of the parents regretted their choice to participate, and they all derived comfort in donating tissue of their child in the hope to help future DIPG patients. In addition, we developed and characterized one of the first DIPG cell cultures from post mortem material. Here we show that obtaining post mortem DIPG tumour tissue for research purposes is feasible with short delay, and that the autopsy procedure is satisfying for participating parents and can be suitable for the development of preclinical DIPG models. © 2012 The Authors.

    2011-09-01

    Full Text Available Abstract Background There is limited data on adolescent mortality particularly from developing countries with unreliable death registration systems. This calls for the use of other sources of data to ascertain cause of adolescent mortality. The objective of this study was to describe the causes of death among Ghanaian adolescents 10 to 19 years in Accra, Ghana utilizing data from autopsies conducted in Korle Bu Teaching Hospital (KBTH. Findings Out of the 14,034 autopsies carried out from 2001 to 2003 in KBTH, 7% were among adolescents. Of the 882 deaths among adolescents analyzed, 402 (45.6% were females. There were 365 (41.4% deaths from communicable disease, pregnancy related conditions and nutritional disorders. Non-communicable diseases accounted for 362 (41% cases and the rest were attributable to injuries and external causes of morbidity and mortality. Intestinal infectious diseases and lower respiratory tract infections were the most common communicable causes of death collectively accounting for 20.5% of total deaths. Death from blood diseases was the largest (8.5% among the non-communicable conditions followed by neoplasms (7%. Males were more susceptible to injuries than females (χ2 = 13.45, p = .000. At least five out of ten specific causes of death were as a result of infections with pneumonia and typhoid being the most common. Sickle cell disease was among the top three specific causes of death. Among the females, 27 deaths (6.7% were pregnancy related with most of them being as a result of abortion. Conclusions The autopsy data from the Korle-Bu Teaching Hospital can serve as a useful source of information on adolescent mortality. Both communicable and non-communicable diseases accounted for most deaths highlighting the need for health care providers to avoid complacency in their management of adolescents presenting with these diseases.

    Objective: To describe mortality pattern and to deter-mine undiagnosed fatal injuries according to autopsy find-ings among road traffic accident victims in Yazd, Iran. Methods: In this retrospective study, 251 victims of road traffic accidents who were admitted to a tertiary trauma hospital over a two-year period (2006 and 2007) and received medical cares were included. Hospital records were reviewed to gather demographic characteristics, road user type, and medical data. Autopsy records were also reviewed to determine actual causes of death and possible undiagnosed injuries occurred in the initial assessment of the emergency unit or during hospitalization. Results: There were 202 males (80.5%) and 49 females (19.5%). The mean (±SD) age of fatalities was 34.1 (±21.5) years. Pedestrian-vehicle accidents were the most common cause of trauma (100 cases, 39.8%). The most common cause of death was central nervous system injury ( 146 cases, 58.1%). The other causes were skull base fractures (10%), internal bleeding (8%), lower limb hemorrhage (8%), skull vault fractures (4%), cervical spinal cord injury (3.6%), airway com-promise (3.2%), and multifactor cases (5.1%), respectively.Thirtysix fatal injuries in 30 victims (12%) mainly contributed to death according to autopsy, but were not diagnosed in initial assessments. The head (72.2%) and cervical spine (13.8%) regions were the two most common sites for undiagnosed injuries. Conclusion: Training courses for emergency unit medical staff with regard to interpreting radiological findings of head and neck and high clinical suspicion for cervical spine injuries are essential to improve the quality of early hospital care and reduce the mortality and morbidity of traffic accident patients.

    Full Text Available OBJECTIVE: To conduct the social audit and verbal autopsy on maternal deaths in Prakasam district, Andhra Pradesh, for the year 2008-2009, done in the year 2010.DESIGN: It was a Community based maternal death review. Maternal deaths in Prakasam district, Andhra Pradesh, during the year 2008-2009, were collected from the District Medical and Health Office, and social audit and verbal autopsy was conducted in the field. METHOD: It was a retrospective community based study. A group of three doctors, which includes an Obstetrician and Gynecologist, a Physician and a specialist from Social and Preventive Medicine, conducted social audit and verbal autopsy by interview method in the field with the family members and neighbors of the victim and analyzed the various social causes and delays leading to the maternal death. RESULTS: The various causes leading to delay in the treatment and to the death of the mother were collected and analyzed. Most of the maternal deaths were young primigravidae of 20 to 24 years. About 65.9% cases were during postpartum period. About 30% of them had not decided whether to go to either government or private hospital for antenatal checkup. 30% to 50% of the family members were not sure or not aware of the danger signs of pregnancy and still 25% of them were home deliveries. The probable medical causes leading to maternal deaths were due to Post-partum hemorrhage, anemia and pregnancy induced hypertension. Most of the cases (about 42.2% were due to delay in receiving appropriate care. About 28.7% of them were due to the delay in recognizing the danger signs of pregnancy. Delay in decision making and delay in reaching the care together forms about 40%.

    Death is the most severe consequence of violence against women. The purpose of this study was to determine the frequency of violence-related deaths among women and the general characteristics of fatal violence cases against women in Istanbul, Turkey. A total of 20,486 forensic autopsies performed between 2006 and 2010, in Istanbul, were retrospectively analyzed. Of these, 537 violence-related deaths among women were included in the study. The victims were investigated in terms of sociodemographic characteristics, exposed type of violence, and autopsy findings. Out of all female deaths (n = 4165), 12.9% were due to violence against women, which comprised 2.6% of all autopsies (n = 20,456) performed during the study period in Istanbul. The median age of the victims was 43 years, and a significant proportion of victims (49.7%) were between the ages of 21 and 40 years. The deaths occurred most commonly in private residences (51.2%, n = 275), whereas the street was the crime scene for 14.5% (n = 78) of cases. Firearm injuries (50.1%, n = 269) were the most common cause of death, followed by stab wounds (28.3%, n = 152) and strangulation (8.4%, n = 45). Among the identified perpetrators, 52.3% were victims' spouses or boyfriends. The perpetrators were female in 4.4% (n = 16) of cases. Istanbul is the most important and cosmopolitan city of Turkey, representing the country's cultural characteristics. Therefore, the data obtained in this study may be strong indicators of violence against women in Turkey.

    Full Text Available Children become physically disabled of predictable and preventable reasons, varying in ratios from country to country. We aimed to help developing preventive medicine programs via our studies on autopsied childhood death cases at Forensic Medicine, Adana Group Administration by listing the origins, causes of death and age distribution of the cases. We presented the childhood death cases autopsied between 1997-2001 at Morgue Department of Council of Forensic Medicine, Adana Group Administration classified by years, origin of death, cause of death, gender and age groups with the table and graphics associated. We discovered 682 childhood age death cases in our study. When investigated through years and age groups, it’s seen that there’s a rising trend in overall number of cases from year to year. 0-6 age group is occupying the highest share among all death cases with 260 incidents which equals 38.12% of the total cases. As per research for origin of death among age groups, we see that 0-6 and 12-15 age groups death origins are mostly “natural”, while at 7-11 age group, origin of death is mostly “accidents” and “suicide” is the one which is significant for 16-18 age group. According to the cause of death distribution among age-groups, it’s seen decease-related deaths are common between 0 and 6 year-old infants while gunshot wounds and drowning are most common in other age groups. We believe developing and practicing regional preventive medicine strategies, created considering local dynamics will cause a significant decrease in death cases related to preventable reasons. Key words: Autopsy, childhood, death.

    Full Text Available Introduction: Incidence of sudden cardiac death (SCD has been steadily increasing all over the world. While knowing the cause of SCD is one of the favorites of the physicians involved with these cases, it is very difficult and challenging task for the forensic physician. The present report is a prospective study regarding cause of SCDs on autopsy examination in four-year period, Bangalore, India. Methods: The present prospective study is based on autopsy observations, carried out for four-year period from 2008 to 2011, and analyzed for cause of SCDs. The cases were chosen as per the definition of sudden death and autopsied. The material was divided into natural and unnatural groups. Finally, on histopathology, gross examination, hospital details, circumstantial, and police reports the cause of death was inferred. Results: A total of 2449 autopsy was conducted of which 204 cases were due to SCD. The highest SCDs were reported in 50-60 years age group (62.24%; n-127, followed closely by the age group 60-69 (28.43%; n-58. Male to female ratio was around 10:1. The maximum number of deaths (n=78 was within few hours (6 hours after the onset of signs and symptoms. In 24 (11.8% cases major narrowing was noted in both the main coronaries, in 87 (42.6% cases in the left anterior descending coronary artery (LAD, and in 18 (51.5% cases in the right coronary artery (RCA. The major cardiac pathology resulting in sudden death was coronary artery disease (n-116; 56.86% and myocardial infarction (n-104; 50.9%. most of the SCDs occurred in the place of residence (n-80; 39.2% followed closely by death in hospital (n-49; 24.01%. Conclusion: Coronary occlusion was the major contributory cause of sudden death with cardiac origin and the highest number of deaths were reported in the age 50-59 years with male to female ratio of 10:1.

    Full Text Available Background: Right atrial mural thrombi (RAMT are often seen in association with cardiac diseases or foreign bodies. Unusual locations at the flutter isthmus and the atrial appendage prompted us to evaluate our 2-year autopsy data on such thrombi. Materials and Methods: In the 2-year retrospective autopsy, the clinical and autopsy records of patients with RAMT were reviewed, with particular reference to the presence of central venous catheter (CVC, its site of insertion, its type, material and size, its duration of placement, and the drugs infused through the catheter. Results: Of the 940 autopsies performed in 2 years, RAMT was seen in 24 hearts and was related to an insertion of a CVC in 23 patients (95.8%. The risk and/or associated factors for this complication were tunneled and polyethylene catheters, Intensive Care Unit admission, infused drugs, underlying cardiac diseases, and pregnancy. A noteworthy feature was the location of the thrombi in the flutter isthmus in 16 hearts (66.7% and atrial appendage in another six hearts. Localized endocarditis/myocarditis and pulmonary thromboembolism were observed in six and four patients, respectively.Conclusions: This autopsy study, which has a high incidence of catheter-related RAMT, does not reflect the true incidence but reiterates the importance of guided insertion of central venous and prompt recognition of thrombus formation.

    The field of plasmonics offers a route to control light fields with metallic nanostructures through the excitation of Surface Plasmon Polaritons (SPPs). These surface waves, bound to a metal dielectric interface, tightly confine electromagnetic energy. Active control over SPPs has potential for applications in sensing, photovoltaics, quantum communication, nano circuitry, metamaterials and super-resolution microscopy. We achieve here a new level of control of plasmonic fields using a digital spatial light modulator. Optimizing the plasmonic phases via feedback we focus SPPs at a freely pre-chosen point on the surface of a nanohole array with high resolution. Digital addressing and scanning of SPPs without mechanical motion will enable novel interdisciplinary applications of advanced plasmonic devices in cell microscopy, optical data storage and sensing.

    1984-03-01

    A tachometer with digital indication was built for measuring the speed of automobile engines with only two digits in the rpm readout. It consists of a Schmitt trigger for shaping input pulses, a pulse counter, a cycle time setting multivibrator and a readout time setting multivibrator, a stabilizer, a flicker suppressor, and a capacitive transducer. The instrument operates from a 12 V battery and draws 180 mA. The transducer includes a 30 to 50 turns coil of PEL 0.5 wire wound around the conductor which connects the ignition coil to the engine distributor and its transistor is mounted on a fin-type heat sink. Tuneup of the tachometer involves matching the transducer capacitor for maximum voltage at minimum current and trimming the readout time setting multivibrator with its adjustable resistor for a 1.5 readout with a 50 Hz input signal.

    2017-06-12

    Membrane punch autopsy (MPA) is a procedure for quantitative foulant analysis of hollow fine fiber (HFF) permeators. In the past, quantitative autopsies of membranes were restricted to spiral wound. This procedure was developed at SWCC laboratories and tested on permeators of two commercial Red Sea reverse osmosis plants. For membrane autopsies, stainless steel hollow bore picks were penetrated to membrane cores and fibers extracted for foulant analysis. Quantitative analysis of extracted materials contained inorganic and organic foulants including bacteria. Fourier transform infrared spectroscopy analysis confirmed the presence of organic fouling functional groups and scanning electron microscopy with energy dispersive X-ray spectroscopy in the presence of diatoms and silica most likely not from particulate sand. API analysis revealed the presence of Shewanella and two Vibrio microbial species confirmed by 16S rDNA sequence library. It was observed that fouling content of HFF cellulose triacetate (CTA) membranes were more than 800 times than polyamide spiral wound membranes.

    Accidental or intentional falls from a height are a form of blunt trauma and occur frequently in forensic medicine. Reports describing elevator accidents as a small subcategory of falls from heights are rare in the medical literature and no report on injury patterns or scene reconstruction of such an accident was found. A case of an accident in a hydraulic elevator with a man falling 3m was examined using post-mortem multi-slice computed tomography (MSCT) and autopsy. The man suffered an unusually extensive trauma and died at the scene. Post-mortem MSCT examination showed a comminute fracture of the skull, the right femur and the first lumbar vertebra. Severe lacerations of the brain with epidural, subdural and subarachnoidal haemorrhages over both hemispheres were diagnosed. Autopsy confirmed these findings. To reconstruct the accident we used radiological and autopsy results as well as findings at the scene.

    This is a retrospective study of autopsy material to highlight the histo-morphological changes in cytomegalovirus (CMV) infection amongst renal allograft recipients. Nineteen out of 80 patients (23.75%) autopsied during a seventeen-year period (1985-2001) had CMV infection. Pulmonary infection was present in 14 out of 19 cases of which four had isolated lung involvement. Likewise, there were two cases each of isolated oesophageal and renal involvement; one case with isolated colonic involvement. The other 10 cases had multi-organ involvement and the organs involved were kidneys (4), esophagus (6), stomach (1), colon (5), adrenals (3), pancreas (3), liver (1) and spleen (1). Pulmonary infection with CMV was associated with acute pneumonitis in 3 cases and lymphocytic interstitial pneumonitis in 9 instances. Four out of 6 cases had acute tubulo-interstitial nephritis induced by CMV and only two cases had no significant inflammatory response. Glomerular involvement in the form of CMV inclusions in the glomeruli was present in only one case. Gastrointestinal CMV infection (15) presented as acute necrotizing ulceration because of predominant endothelial involvement. Post transplant survival period varied from one month to three years, with majority (14) of the patients having survived for less than one year.

    2016-01-01

    Full Text Available Background. Tuberculosis (TB is a major cause of morbidity and mortality globally. Many cases are diagnosed on autopsy and a subset of patients may require surgical intervention either due to the complication or sequelae of TB. Materials and Methods. 40 cases of resected lung specimens following surgery or autopsy in which a diagnosis of pulmonary tuberculosis was made were included. Histopathological pattern analysis of pulmonary tuberculosis along with associated nonneoplastic changes and identification of Mycobacterium tuberculosis bacilli was done. Results. The mean age of diagnosis was 41 years with male predominance (92.5%. Tuberculosis was suspected in only 12.1% of cases before death. Seven cases were operated upon due to associated complications or suspicion of malignancy. Tubercular consolidation was the most frequent pattern followed by miliary tuberculosis. The presence of necrotizing granulomas was seen in 33 cases (82.5%. Acid fast bacilli were seen in 57.5% cases on Ziehl-Neelsen stain. Conclusion. Histopathology remains one of the most important methods for diagnosing tuberculosis, especially in TB prevalent areas. It should be considered in the differential diagnosis of all respiratory diseases because of its varied clinical presentations and manifestations.

    2013-01-01

    Full Text Available Introduction: Neonatal mortality is increasingly important be-cause the proportion of under-five deaths that occur during the neonatal period is increasing as under-five mortality declines. Because declines in the neonatal mortality rate are slower the share of neonatal deaths among under-five deaths increased from about 36 percent in 1990 to about 43 percent in 2011. There is a need to identify and address the causes of neonatal mortality to achieve the MDG of 31 under five deaths per 1000 live births per year. Objective: To ascertain the causes of neonatal mortality in the area covered by CHC Natwara (Shahpura Block of Jabalpur district using verbal autopsy method. Materials and Methods: Neonatal deaths registered during the period of 1st April 2005 to 31st March 2006 at CHC Natwara of District Jabalpur of MP were studied. Total 69 neonatal deaths were studied using standard verbal autopsy questionnaire. Causes of deaths were ascertained from the filled in VA questionnaire taking the help of a pediatrician. Results: Mother was main respondent in 50.72% cases followed by father (23.1%. Sepsis was the most important cause of death particularly in the late neonatal period. Birth asphyxia, pneumonia and RDS were the other important causes of death contributing predominantly to the early neonatal deaths. The most important predisposing cause of death was LBW/prematurity. Conclusion: Most of the deaths are directly or indirectly related to infection and nutrition and are therefore amenable to prevention.

    This study analyses psychological autopsies and contextualizes problems and issues that led to elderly people taking their own lives in the city of Rio de Janeiro between 2004 and 2007. The study began with an analysis of 26 expert findings of elderly men and women who committed suicide in the central, northern and southern areas of Rio de Janeiro. The sample was contacted by letter and telephone and after that, by a one-on-one conversation. Eight psychological autopsies were conducted, in which identification data and family genograms were collected followed by an interview to profile the life style and the reasons for the self-inflicted violence. The interviewees were family members, friends and acquaintances of the victims. The suicides are associated with depression, serious physical and mental illness, as well as socio-cultural factors related to professional and socio-economic decline. The suicides occurred with and without family support, with and without medical care. The cumulative fragility of personal and social resources within the life cycle reveals that the risk of suicide among the elderly demands permanent care from the public health authorities.

    Upon detection of foreign-body embolization to the central nervous system (CNS) following a specific invasive cardiovascular procedure in 1 autopsied child, we undertook a quality assurance analysis to determine whether other patients had had similar events. Autopsies of all infants and children with history of cardiac catheterization, heart surgery on cardiopulmonary bypass, and/or extracorporeal membrane oxygenation over a 5-year period at a single tertiary care institution were reviewed for light-microscopic evidence of foreign material. Of the 24 patients meeting clinical criteria (13 females, 11 males; ages 6 days to 20 years, median age 7.5 months), 8 (33%) had foreign embolic material to the CNS. The material was associated with a cellular inflammatory reaction in all cases, with a subset associated with infarcts. No embolic foreign material was detected in 14 age-matched patients without history of cardiovascular procedures. Particles acquired from ex vivo manipulation of a catheter type utilized in at least 1 of the affected patients demonstrated similar histologic characteristics. We conclude that, in addition to recognized risks of hypoxic-ischemic brain damage in congenital cardiopulmonary disease, potential brain insult exists in the form of instrumentation-related foreign emboli to the cerebral vasculature. Cardiac catheters are a potential source of foreign embolic material. © 2017 American Association of Neuropathologists, Inc. All rights reserved.

    2009-06-01

    A 48-years-old man presented with slowly progressive bradykinesia, personality change and rapidly progressive left hemiparesis. On admission, he presented dementia, poor judgment, left hemiparesis. MRI revealed a widespread high intensity area in right hemisphere and MRA was almost normal. Serological tests of serum and CSF demonstrated high titers of antibodies to Treponema pallidum. He was treated for syphilis with daily penicillin injections without improvement. He died of sepsis eight months after admission. At autopsy, the brain weighed 1,100 g and the right cerebral hemisphere was atrophic, especially in frontal base, temporal, parietal, angular, and posterior regions covered by thickened, fibrotic leptomeninges. Microscopically, chronic meningoencephalitis was observed. Severe neuronal loss with gliosis was seen in the right cerebral cortices. Scattered rod-shaped microglia and inflammatory cell infiltration were visible in the cerebral parenchyma. The dorsal column of the spinal cord was not involved and meningovascular syphilis was unclear. The distribution of the encephalitic lesions was well correlated with the clinical and neuroradiological findings. This was a rare autopsy case presenting Lissauer's general paresis, clinically manifesting as rapidly progressive stroke-like episode.

    2014-04-01

    We assessed the technical performance and robustness of the point-of-care test for C-reactive protein (CRP) NycoCard CRP for use in forensic autopsy cases. The results of 17 of 39 cadaver blood samples that had CRP in the range effectively measured by the NycoCard (5-120mg/l) correlated well (r=0.99) with those of quantitative latex agglutination immunoassay (turbidimetry), and the out-of-range NycoCard results were fully consistent with those obtained by turbidimetry. For the ten sera whose CRP >120mg/l according to NycoCard, a significant correlation (r=0.98) was observed between values multiplied by the dilution ratio and those of turbidimetry. No significant differences were observed after a freeze-thaw procedure. In addition, CRP results using recombinant human CRP spiked with hemoglobin up to 80g/l were not significantly different from the unspiked results in PBS. The test allows reliable and cost-effective on-site measurement of CRP from a small volume of serum (5μl) with simple equipment. This semi-quantification method of CRP should be useful for diagnosis during autopsy.

    Patients with malignant mesothelioma typically present with a pleural effusion or pleural thickening and masses. A rare autopsy case of mesothelioma presenting with multiple bilateral lung nodules without clinically detectable pleural lesions is presented. A definitive diagnosis of the video-assisted thoracic surgery specimen could not be made, though a pattern of fibrosis mimicking organizing pneumonia was identified. Despite corticosteroid therapy, follow-up chest computed tomography showed enlargement of multiple nodules accompanied by the appearance of pleural thickening and effusions. The patient died of respiratory failure 11 months after initial presentation. Autopsy and retrospective analysis of the video-assisted thoracic surgery specimen using a p16 fluorescence in situ hybridization assay showed p16 homozygous deletion. The final diagnosis was sarcomatoid mesothelioma, and the lung nodules were intrapulmonary metastases from a clinically undetectable pleural sarcomatoid mesothelioma. It is important both to consider the possibility of mesothelioma with unusual clinical, radiological and pathological presentations and to remember that p16 fluorescence in situ hybridization analysis can play an important role in the diagnosis of mesothelioma.

    2017-02-01

    Leptomeningeal dissemination of low-grade Schwann cell neoplasms is an exceptionally rare occurrence and has not been well documented in the literature. We encountered 2 cases of leptomeningeal dissemination of low-grade Schwann cell neoplasms. Patient 1 was a 63-year-old woman with neurofibromatosis type 1 and a progressive low-grade malignant peripheral nerve sheath tumor developing from a diffuse/plexiform orbital neurofibroma that arose in childhood. The neoplasm demonstrated local and leptomeningeal dissemination intracranially leading to the patient's death. There was partial loss of H3K27 tri-methylation, p16 and collagen IV. Patient 2 was a 60-year-old man without neurofibromatosis type 1 who presented with cranial nerve symptoms and a disseminated neoplasm with a Schwann cell phenotype. The neoplasm stabilized after irradiation and chemotherapy, but the patient died of medical complications. Autopsy findings documented disseminated leptomeningeal disease in the intracranial and spinal compartment. H3K27M tri-methylation was preserved. The clinicopathologic and autopsy findings are studied and presented, and the literature is reviewed.

    2017-01-01

    We report an extremely rare case of a pancake kidney with a single ureter. During the medicolegal autopsy on the body of a traffic accident victim, the kidneys were not located in the abdomen. The anterior surfaces of both kidneys were completely fused in the pelvic cavity, and the kidney was shaped like a pancake. This pancake kidney had accessory renal arteries around it and one renal vein from each kidney. The left renal vein was much smaller in diameter than the right one. There were two major calyces, one each from each kidney. The major calyces joined to form a single renal pelvis from both the kidneys, which continued as a single ureter. The renal pelvis and ureter lay posterior to the pancake kidney. Urologists and pelvic surgeons should be aware of the variant anatomy of the pancake kidney, particularly concerning its vasculature, to prevent unexpected catastrophic bleeding. If the kidneys are not located in the abdominal cavity, the autopsy surgeon must consider the possibility of its presence in the pelvic cavity. This could be especially important during medicolegal investigations into allegations of missing kidneys and unlawful kidney transplantations.

    This study used autopsy to evaluate the prevalence of cholelithiasis and its associated risk factors in a population of healthy, young subjects who suffered a violent or natural death. This study is a prospective evaluation of autopsies of 446 individuals from 2011 to 2013 in Brazil. Of that sample, 330 (74%) subjects died from violent deaths and 116 (26%) died naturally. The presence of biliary calculi, previous cholecystectomy, gender, age, ethnicity, body mass index (BMI) and alcohol use were evaluated. In the natural death group, 6.9% (95% CI 3.39 to 13.28) (3.08% of the male subjects and 11.76% of the female subjects) exhibited evidence of gallbladder disease. In the violent death group, only 2.12% (95% CI 0.96 to 4.43) (2.17% of the male subjects and 1.85% of the female subjects) of the subjects exhibited evidence of gallbladder disease. Age was correlated with the prevalence of gallbladder disease, but BMI was correlated with only gallbladder disease in the natural death group. This population has the lowest prevalence of cholelithiasis in the Americas. Dietary habits, physical activity, ethnicity, alcohol consumption and genetic factors may be responsible for this low prevalence.

    2011-12-01

    Intracorporeal concealment of illicit drugs is a rare observation at coronial autopsy examinations. The article reports 5 cases of accidental drug overdoses at the Westmead Coronial Morgue, Sydney New South Wales, over a 6-year period with evidence of intracorporeal drug concealment known as body packing or body stuffing. Three different forms of anatomic concealment of drugs are illustrated, Case 2 involving therapeutic medication in the form of glass ampoules for parenteral injection not previously reported. Three deaths were the result of acute toxicity due to polydrug abuse rather than as a consequence of the body packing behavior and rupture of the drug packaging, with the intracorporeal drug concealments an adjunct finding at the autopsy examinations. The cause of death in Case 3 was the direct result of acute cocaine intoxication due to rupture of drug packages in the rectum and mucosal absorption. The article details forensic sociological aspects of drug concealment and subcultural group human behavior that can assist in providing information for the initiation of investigations.

    Full Text Available Introduction: In this retrospective study, we decided to determine the death causes and severity of injuries in traffic accidents according to reports of the forensic medical center of Yazd. Methods: A total of 251 fatalities due to traffic accidents that had undergone autopsy examinations at the Yazd forensic medicine center from2006 till 2008 were included in the study by census method. Data regarding gender, road user type, type of vehicle (car, motorcycle, autobus or minibus, consciousness level, and intensive care unit (ICU admission was gathered. For evaluation of injury severity, we used Injury Severity Score (ISS. Results: The population under study consisted of 202 men (80.5% and 49 women (19.5% with an average age of 34.1 years (range: 1-89 years. Motorcycle-pedestrian accidents were the most common type of injury (100, 39.8%. Head (220, 87.6% and face (169, 67.3% were the two most common sites of injuries. Mean (±SD of ISS was 23.2 (±10.4. According to autopsy records, the main cause of death was head trauma (146, 58.1%. Conclusion: Public awareness in terms of primary prevention of road accidents should be considered important. Also, regarding the high prevalence of brain injuries and complications associated with skull fractures, accessibility to neurosurgeons and availability of imaging devices have an important role in decreasing the mortality rate of traffic accidents.

    Full Text Available Small-cell neuroendocrine carcinoma is a well-known aggressive neoplasia, which is usually associated with a poor prognosis. The lung is the most common primary site, but other organs may be involved, especially those of the digestive tract. The authors report the case of a 71-year-old Caucasian, male patient who was admitted because of congestive heart failure and loss of vision accompanied by right proptosis. Skull and sinuses computed tomography showed a tumoral mass involving the posterior region of the right eye, local bones, and paranasal sinuses. Because of severe hemodynamic instability, the patient died and no diagnostic investigation could be performed. Autopsy findings revealed small-cell neuroendocrine carcinoma of the esophagus and metastases to the posterior region of the right ocular globe, which affected the sinuses, the muscles of the ocular region, the orbit bones, the skull, the meninges and the brain, plus the liver, adrenal glands, and the pericardium. This case called the author’s attention to the extent of the metastatic disease in a patient who was firstly interpreted as presenting solely with congestive heart failure. The autopsy findings substantially aid the understanding of the immediate cause of death.

    2012-02-10

    Tolperisone (Mydocalm) is a centrally acting muscle relaxant with few sedative side effects that is used for the treatment of chronic pain conditions. We describe three cases of suicidal tolperisone poisoning in three healthy young subjects in the years 2006, 2008 and 2009. In all cases, macroscopic and microscopic autopsy findings did not reveal the cause of death. Systematic toxicological analysis (STA) including immunological tests, screening for volatile substances and blood, urine and gastric content screening by GC-MS and HPLC-DAD demonstrated the presence of tolperisone in all cases. In addition to tolperisone, only the analgesics paracetamol (acetaminophen), ibuprofen and naproxen could be detected. The blood ethanol concentrations were all lower than 0.10 g/kg. Tolperisone was extracted by liquid-liquid extraction using n-chlorobutane as the extraction solvent. The quantification was performed by GC-NPD analysis of blood, urine and gastric content. Tolperisone concentrations of 7.0 mg/l, 14 mg/l and 19 mg/l were found in the blood of the deceased. In the absence of other autopsy findings, the deaths in these three cases were finally explained as a result of lethal tolperisone ingestion. To the best of our knowledge, these three cases are the first reported cases of suicidal tolperisone poisonings.

    2014-05-01

    Full Text Available An autopsy case report of Trousseau's syndrome caused by intrahepatic cholangiocarcinoma is presented, and seven previously reported cases are reviewed. A 73-year-old woman experiencing light-headedness and dementia of unknown cause for 6 months developed severe hypotonia. A hypointense lesion compatible with acute cerebral infarction was detected by magnetic resonance imaging. Abdominal computed tomography revealed an ill-defined large liver mass in the right lobe. The mass was not further investigated because of the patient's poor condition. She died of multiple organ failure, and an autopsy was conducted. Postmortem examination revealed intrahepatic cholangiocarcinoma, fibrous vegetations on the mitral valves and multiple thromboemboli in the cerebrum, spleen and rectum. Trousseau's syndrome is defined as an idiopathic thromboembolism in patients with undiagnosed or concomitantly diagnosed malignancy. This syndrome is encountered frequently in patients with mucin-producing carcinomas, while the incidence in patients with intrahepatic cholangiocarcinoma is uncommon. We found that tissue factor and mucin tumor marker (CA19-9, CA15-3 and CA-125 expression in cancer cells may be involved in the pathogenesis of thromboembolism. A patient with unexplained thromboembolism may have occult visceral malignancy; thus, mucin tumor markers may indicate the origin of a mucin-producing carcinoma, and postmortem examination may play an important role in revealing the hidden malignancy.

    GLUT3 is expressed in rat muscle, but this glucose transporter protein has not been identified previously in adult human skeletal muscle. We quantified the rapidity of disappearance of mRNA and protein from human skeletal muscle at room temperature and at 4 degrees C. Fifty percent of the immunologically detectable GLUT3 protein disappeared by 1 hour at 20 degrees C and by 2 hours at 4 degrees C. mRNA for GLUT3 was decreased 50% by 2.2 hours at 20 degrees C and by 24 hours at 4 degrees C. Half of the measurable mRNAs for GLUT4, glyceraldehyde 3-phosphate dehydrogenase (GAPDH), alpha-actin, and beta-myosin disappeared by 0.8 to 2.1 hours at 20 degrees C and by 5.0 to 16.6 hours at 4 degrees C. Previous conclusions that GLUT3 is not expressed in human muscle were likely drawn because of artifacts related to degradation of GLUT3 protein in the specimens prior to study. Because of the rapid degradation of protein and mRNA, autopsy specimens of muscle must be obtained within 6 hours of death, and even then, protein and mRNA data will likely dramatically underestimate their expression in fresh muscle. Some previously published conclusions and recommendations regarding autopsy specimens are not stringent enough to consistently yield useful protein and mRNA.

    Multiple system atrophy (MSA) is divided into two clinical subtypes: MSA with predominant parkinsonian features (MSA-P) and MSA with predominant cerebellar dysfunction (MSA-C). We report a 71-year-old Japanese man without clinical signs of MSA, in whom post mortem examination revealed only slight gliosis in the pontine base and widespread occurrence of glial cytoplasmic inclusions in the central nervous system, with the greatest abundance in the pontine base and cerebellar white matter. Neuronal cytoplasmic inclusions (NCIs) and neuronal nuclear inclusions (NNIs) were almost restricted to the pontine and inferior olivary nuclei. It was noteworthy that most NCIs were located in the perinuclear area, and the majority of NNIs were observed adjacent to the inner surface of the nuclear membrane. To our knowledge, only four autopsy cases of preclinical MSA have been reported previously, in which neuronal loss was almost entirely restricted to the substantia nigra and/or putamen. Therefore, the present autopsy case of preclinical MSA-C is considered to be the first of its kind to have been reported. The histopathological features observed in preclinical MSA may represent the early pattern of MSA pathology.

    Children are at increased risk for various causes of injury from accidents. Accidents are, by far, the leading cause of death among children and adolescents. The aim of this study is to evaluate the lethal childhood accidents in İstanbul by age groups. Reports of autopsies performed between 2001 and 2005 in the Morgue Department of the Council of Forensic. Medicine in Istanbul (n :16853) are examined retrospectively. 833 deaths from accidents in children aged 0-18 years are investigated into the study. The parameters of age, gender, types of accidents and causes of death are evaluated. The accidents account for 47.3% of the deaths among children aged 0-18 years. Of 833 cases, 601 (73%) are male and 232 (27%) are female. The female to male ratio is 1/2.6. The highest rate of death from accidents is at the group of 15-18 years. The primary causes of accidental childhood deaths are motor vehicle accidents (23.1%), followed by drowning (20,1%), poisoning (15.7%), and fall from height (15.5%). The incidence and types of trauma vary with socio-economic status and culture. İstanbul, where this study is conducted in, has approximately 3000 autopsy number annually. Therefore, it provides an important database. Copyright © 2011 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

  18. Pattern of Suicide: A Review of Autopsies Conducted at Moi Teaching and Referral Hospital in Eldoret Kenya

    2015-06-01

    Full Text Available Problem statement. Suicide is one of the ten leading causes of death in the world, accounting for more than 400,000 deaths annually. The pattern of suicide and the incidence of suicide vary from country to country. Cultural, religious and social values play some role in suicide. Currently, there is no data regarding the incidence of suicide in Kenya. Setting. Moi Teaching and Referral Hospital Mortuary. Study population. A seven-year retrospective study of all the autopsies performed at the Moi Teaching and Referral Hospital was analysed and the cases that were definitely determined as suicides were further studied. Objective. To characterize the pattern of suicide cases through autopsies conducted at MTRH mortuary between the years 2005 to 2012. Methodology. Retrospective descriptive cross-sectional study. Suicide cases were identified from the MTRH autopsy record books. From these record books, the autopsy number was used to retrieve the pathologists autopsy report. Data regarding age, gender and methods of suicide was retrieved and entered into a data collection form. Data analysis: Data collected was analysed using Stata version 10. Results. There were 213 autopsies performed. Majority were male 180(85%. The subjects had a median age of 29(IQR: 23–37 years. Organophosphate poisoning was the most preferred method followed by hanging. Organophosphate poisoning accounted for 195(91.54% and hanging for 17(7.98% of the subjects. Conclusion. The preferred methods of suicide were poisoning and hanging. The study may have missed some cases where the relatives could have declined for the postmortem procedure and hence the body released without postmortem examinations.

    The aim of the present study is to offer our experience concerning post-mortem magnetic resonance (PMMR) in foetal death cases and an evaluation of the differences between the findings acquired by PMMR and by forensic autopsy. Fifteen foetuses were recruited from July 2014 to December 2015. These had suffered intrauterine death in women in the 21st to 38th week of gestation who were treated in the emergency department for non-perception of foetal movements. We performed a PMMR on foetuses, 3 ± 1 days on average from the time of death, and then a complete forensic autopsy was performed. All 15 foetuses were examined with a whole-body study protocol, starting from the skull, down to and including the lower limbs. The total time of examination ranged from 20 to 30 min in each case. The external evaluation and description of post-mortem phenomena (maceration), record of the weight and detection and the various measurements of foetal diameters were evaluated before performing autopsy. A complete histopathological study was performed in each case. Out of 15 cases examined, eight were negative for structural anatomical abnormalities and/or diseases, both in the preliminary radiological examination and the traditional autopsy. In the remaining seven cases, pathological findings were detected by PMMR with corresponding results at autopsy. PMMR can provide useful information on foetal medical conditions and result in improved diagnostic classification. It may enable the planning of a more suitable technique before proceeding to autopsy, including focusing on certain aspects of organ pathology otherwise not detectable. The association between PMMR, post-mortem examination and related histological study of the foetus-placenta unit could help reduce the percentage of cases in which the cause of foetal death remains unexplained. Lastly, it may allow a selective sampling of the organ in order to target histological investigations.

    Enzyme replacement therapy is standard of care for patients with Gaucher disease, as it significantly improves skeletal, visceral, and hematological symptoms. Few pathological studies have documented the extent of pathological findings in treated patients. Autopsy findings in five treated patients, who ultimately developed parkinsonism, ranged from the complete absence of Gaucher pathology to extensive involvement of multiple tissues, without correlation to age, genotype, spleen status, or dose/duration of therapy. Additional autopsies may elucidate modifiers and biomarkers contributing to disease burden and response to therapy.

    Many factors affect the integrity of messenger RNA from human autopsy tissues including postmortem interval (PMI) between death and tissue preservation and the pre-mortem agonal and disease states. In this communication, we describe RNA isolation and characterization of 389 samples from 18 different tissues from elderly donors who were participants in a rapid whole-body autopsy program located in Sun City, Arizona ( www.brainandbodydonationprogram.org ). Most tissues were collected within a PMI of 2-6 h (median 3.15 h; N = 455), but for this study, tissue from cases with longer PMIs (1.25-29.25 h) were included. RNA quality was assessed by RNA integrity number (RIN) and total yield (ng RNA/mg tissue). RIN correlated with PMI for heart (r = -0.531, p = 0.009) and liver (r = -558, p = 0.0017), while RNA yield correlated with PMI for colon (r = -485, p = 0.016) and skin (r = -0.460, p = 0.031). RNAs with the lowest integrity were from skin and cervix where 22.7 and 31.4 % of samples respectively failed to produce intact RNA; by contrast all samples from esophagus, lymph node, jejunum, lung, stomach, submandibular gland and kidney produced RNA with measurable RINs. Expression levels in heart RNA of 4 common housekeeping normalization genes showed significant correlations of Ct values with RIN, but only one gene, glyceraldehyde-3 phosphate dehydrogenase, showed a correlation of Ct with PMI. There were no correlations between RIN values obtained for liver, adrenal, cervix, esophagus and lymph node and those obtained from corresponding brain samples. We show that high quality RNA can be produced from most human autopsy tissues, though with significant differences between tissues and donors. The RNA stability and yield did not depend solely on PMI; other undetermined factors are involved, but these do not include the age of the donor.

  7. Mortality patterns in Vietnam, 2006: Findings from a national verbal autopsy survey

    2010-03-01

    Full Text Available Abstract Background Accurate nationally representative statistics on total and cause-specific mortality in Vietnam are lacking due to incomplete capture in government reporting systems. This paper presents total and cause-specific mortality results from a national verbal autopsy survey conducted first time in Vietnam in conjunction with the annual population change survey and discusses methodological and logistical challenges associated with the implementation of a nation-wide assessment of mortality based on surveys. Verbal autopsy interviews, using the WHO standard questionnaire, were conducted with close relatives of the 6798 deaths identified in the 2007 population change survey in Vietnam. Data collectors were health staff recruited from the commune health station who undertook 3-day intensive training on VA interview. The Preston-Coale method assessed the level of completeness of mortality reporting from the population change survey. The number of deaths in each age-sex grouping is inflated according to the estimate of completeness to produce an adjusted number of deaths. Underlying causes of death were aggregated to the International Classification of Diseases Mortality Tabulation List 1. Leading causes of death were tabulated by sex for three broad age groups: 0-14 years; 15-59 years; and 60 years and above. Findings Completeness of mortality reporting was 69% for males and 54% for females with substantial regional variation. The use of VA has resulted in 10% of deaths being classified to ill-defined among males, and 15% among females. More ill-defined deaths were reported among the 60 year or above age group. Incomplete death reporting, wide geographical dispersal of deaths, extensive travel between households, and substantial variation in local responses to VA interviews challenged the implementation of a national mortality and cause of death assessment based on surveys. Conclusions Verbal autopsy can be a viable tool to identify cause

    2011-12-01

    Full Text Available Abstract Background Minimally invasive autopsy by post mortem magnetic resonance (MR imaging has been suggested as an alternative for conventional autopsy in view of the declining consented autopsy rates. However, large prospective studies rigorously evaluating the accuracy of such an approach are lacking. We intend to compare the accuracy of a minimally invasive autopsy approach using post mortem MR imaging with that of conventional autopsy in fetuses, newborns and children for detection of the major pathological abnormalities and/or determination of the cause of death. Methods/Design We recruited 400 consecutive fetuses, newborns and children referred for conventional autopsy to one of the two participating hospitals over a three-year period. We acquired whole body post mortem MR imaging using a 1.5 T MR scanner (Avanto, Siemens Medical Solutions, Enlargen, Germany prior to autopsy. The total scan time varied between 90 to 120 minutes. Each MR image was reported by a team of four specialist radiologists (paediatric neuroradiology, paediatric cardiology, paediatric chest & abdominal imaging and musculoskeletal imaging, blinded to the autopsy data. Conventional autopsy was performed according to the guidelines set down by the Royal College of Pathologists (UK by experienced paediatric or perinatal pathologists, blinded to the MR data. The MR and autopsy data were recorded using predefined categorical variables by an independent person. Discussion Using conventional post mortem as the gold standard comparator, the MR images will be assessed for accuracy of the anatomical morphology, associated lesions, clinical usefulness of information and determination of the cause of death. The sensitivities, specificities and predictive values of post mortem MR alone and MR imaging along with other minimally invasive post mortem investigations will be presented for the final diagnosis, broad diagnostic categories and for specific diagnosis of each system

  9. Investigation of the role of computed tomography as an adjunct to autopsy in the evaluation of stillbirth.

    LENUS (Irish Health Repository)

    2012-01-31

    INTRODUCTION: The number of parents agreeing to autopsy following stillbirth is declining, which has undermined clinicians\\' ability to assess causes of intrauterine death and can impact counselling regarding recurrence. Post-mortem radiological imaging is a potential alternative method of investigating perinatal loss. The aim of this study was to assess the role of multi-detector computed tomography (MDCT) in the investigation of stillbirth. STUDY DESIGN: Following ethical approval and written consent, parents were offered MDCT of the stillborn infant. MDCT was performed with 3D reconstruction, and images were analysed for image quality, anthropomorphic measurements and pathologic findings. Body part and organ-specific measurements were performed; including head, chest and abdominal circumferences, and muscle and liver mass was also measured. Findings were correlated with obstetric history, post-mortem skeletal survey (plain radiography), and formal autopsy. RESULTS: Fourteen third-trimester stillborn infants were scanned. Image quality was moderate to excellent for most body structures. CT was better than plain radiography for imaging skeletal structures and large solid organs and demonstrated a range of pathologies including renal vein thrombosis, mesenteric calcification and skeletal hyperostosis that were not seen on plain radiographs. MDCT did not overlook autopsy findings and provided some additional information. CONCLUSION: This study confirms the feasibility of MDCT in the investigation of third trimester stillbirth. MDCT image quality is acceptable and the examination can demonstrate a range of anatomic and pathologic findings. Initially, its value may be as an important adjunct to conventional autopsy.

    The aim was to study the causes of maternal mortality (MM) and the percent of concordance between the clinical diagnosis and the autopsy findings. The autopsies of maternal death (1980-1999) from the Hospital de Especialidades, Centro Médico del Noreste, IMSS in Monterrey, México, were analyzed. The cases were classified in directly obstetric maternal mortality (DOM) and indirectly obstetric maternal mortality (IOM), the causes were studied and the percent of concordance between pre- and post-mortem diagnosis was determined. There were 124 deaths. Autopsy was performed in 61 (49.1%) women. In 55 cases the clinical file and the autopsy protocol were available. This was our sample for study. Sixty percent of the cases were DO. Causes of DOM were: specific hypertensive pregnancy disease (SHPD) (51.6%), sepsis (35.5%), hypovolemic shock (9.7%), anesthetic accidents (3%); causes of IOM were: sepsis (41.7%), malignancies (16.7%), hematological diseases (12.5%), cardiopathy and systemic arterial hypertension (12.5%), hepatic disorders (12.5%), and Superior Longitudinal Sinus thrombosis (4%). A 100% clinical-pathological concordance was observed in DOM cases, while only a 41.6% was found in IOM cases. In those cases of sepsis (IOM), the etiologic agents were identified only in 20% before death. The early detection and treatment of SHPD and the prevention of sepsis should decrease the MM. This study showed some weakness in the Health Services that should be improved.

    2013-01-01

    Full Text Available A 57-year-old Japanese man visited our hospital with a moist cough. Chest radiographic imaging showed a left hilar shadow. Adenocarcinoma cells were found on cytologic screening of fresh sputum. Although multiple metastases including brain were detected, no tumor was observed in the kidneys. The patient underwent whole-brain irradiation and chemotherapy for advanced-stage lung cancer. One month before his death, carcinomatous meningitis was detected. Hyponatremia, hypo-osmolality, and hypertonic urine suggested the syndrome of inappropriate antidiuresis. Restricting water intake improved the hyponatremia; however, he developed fever and hematuria. Despite systemic administration of an antibacterial drug, he died. Primary tumor in the lung was absent, but adenocarcinoma of the right kidney was evident on autopsy. Lectin histochemical analysis of the carcinoma revealed its distal nephron origin, confirming collecting duct carcinoma. Severe carcinomatous meningitis, which is possibly caused the syndrome of inappropriate antidiuresis, was observed, with no cancer involvement of the pituitary gland and hypothalamus.

    2008-04-01

    Full Text Available Kidney disease frequently complicates malignancy and its treatment. Although many solid and hematologic cancers may involve the renal parenchyma, clinical sequelae are usually not prominent. Published reports cite membranous nephropathy as the most common malignancy-associated glomerulopathy, occurring with many carcinomas and occasionally with leukemia and lymphoma followed by minimal change disease. Rarely membranoproliferative glomerulonephritis (MPGN has been reported in patients with malignancy. The mechanism by which malignancy induces disease remains unproved, but may involve deposition of tumor antigen in the subepithelial space with in situ immune complex formation and subsequent complement activation. Treatment of the underlying malignancy may lead to resolution of nephrotic syndrome, lending indirect support to this theory. We report a rare autopsy case of a patient with metastatic carcinoma (with unknown primary associated with MPGN. The association between MPGN and metastatic carcinoma with unknown primary is uncommon and has not been previously reported in the literature.

    2016-02-01

    In Mexico, suicides are increasing in certain latitudes where local rates have grown to levels of alert; suicide is also the second most common cause of death for the group aged 15 to 19. The psychological autopsy method was utilized to uncover and analyze common factors in all of the registered suicides within 2011 and 2012 in a small town of the state of Guanajuato, located in the center of Mexico. A total of nine decedents were analyzed, and 22 interviews were conducted. The most salient factors were as follows: poverty, financial stress, substance abuse, low levels of education, conflictive relationships, and a poor handling of emotions. The concepts of social exclusion and vulnerability were employed to analyze suicides as symptoms of a much deeper problem of this country, suggesting that anomie and social malady are nowadays important suicidal factors, mostly for children and young people.

    Wilson's disease is an autosomal recessive disease resulting in defective copper metabolism, which is usually seen in young adults, predominantly affecting liver and brain. Although it is not uncommon in India, variation in epidemiology, clinical presentation and course are reported. However, community-based incidence and prevalence rates are not available in India and incidences are limited to hospital based reports. Most often, the diagnosis is delayed. We present a clinical autopsy case in a 39 year-old female who had presented with clinical symptoms at 18 years of age. The duration of illness was 21 years. Patient's parent had consanguineous marriage and the younger sibling had died at 5 years of age with similar complaints.

    The extent and importance of genotype heterogeneity of Pneumocystis carinii f. sp. hominis within lungs have not previously been investigated. Two hundred forty PCR clones obtained from respiratory specimens and lung segments from three patients with fatal P. carinii pneumonia were investigated....... Not all genotypes present in the lungs at autopsy were detected in the diagnostic respiratory samples. Compartmentalization of specific ITS and mtLSU rRNA sequence types was observed in different lung segments. In conclusion, the interpretation of genotype data and in particular ITS sequence types...... in the assessment of epidemiological questions should be cautious since genotyping done on respiratory samples cannot a priori be assumed to represent all genotypes present within the lung....

    Menenteau, Sandra

    2012-01-01

    Murder is perpetrated, suicide is committed and lethal accidents happen everywhere, even in the heart of the French country. In the 19th century, law often appealed to the lights of experts. During criminal investigation, improvisation and men's adaptation were important, although forensic autopsy was official and necessary. Sometimes the magistrates appealed to young people, not used to that kind of reports, who could only remind some bits of the forensic courses they had followed when they were students. As for the specialists, the circumstances often led them to examine--as Baudelaire would say--the "decaying carcass," in a dark and suffocating ruined house, on the kitchen table, and with a simple scapel.

    A 62-year-old man with pain in his hip joints and back was admitted to our hospital. His chest radiograph and CT showed a huge mass extending from the left upper pericardium to the left hilum, but no pleural effusion or other lesions. A contrast-enhanced abdominal CT showed multiple metastases to bones and both kidneys. Bronchoscopy revealed obstruction of the left B3 by a visible tumor. The biopsy specimens of the initial immunohistochemical staining were slightly positive for calretinin. However, we diagnosed the condition as sarcomatoid carcinoma of the lung on the basis of the clinical evaluation. Although radiotherapy was administered, his condition rapidly deteriorated and he died due to progression of the disease. Autopsy revealed extensive invasion, suggesting mesothelioma. Therefore, immunohistochemical staining was performed; the findings revealed sarcomatoid malignant mesothelioma. In conclusion, we encountered a rare case of sarcomatoid malignant mesothelioma (stage IV).

    A Japanese man in his 30s who had congenital cerebral palsy was found unresponsive in bed. His death was confirmed after resuscitation attempts. He had a history of occasional falling (despite the use of walking sticks and a wheelchair) owing to a slowly progressive gait disturbance, and had a medical examination without full neurological re-examination. Autopsy revealed gangliocytoma in the medulla oblongata, which was diagnosed as the cause of death. Although gangliocytoma is a well-differentiated benign tumor, the almost total replacement of the medulla oblongata by the tumor cells was assumed to result in ataxia via the olivocerebellar tract and secondary cerebellar atrophy, followed by central hypoventilation and death of the patient. The symptoms caused by gangliocytoma may be overlooked owing to long-standing cerebral palsy. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  2. Cutting the Flesh: Surgery, Autopsy and Cannibalism in the Belgian Congo.

    Within the colonial setting of the Belgian Congo, the process of cutting the body, whether living or dead, lent itself to conflation with cannibalism and other fantastic consumption stories by both Congolese and Belgian observers. In part this was due to the instability of the meaning of the human body and the human corpse in the colonial setting. This essay maps out different views of the cadaver and personhood through medical technologies of opening the body in the Belgian Congo. The attempt to impose a specific reading of the human body on the Congolese populations through anatomy and related Western medical disciplines was unsuccessful. Ultimately, practices such as surgery and autopsy were reinterpreted and reshaped in the colonial context, as were the definitions of social and medical death. By examining the conflicts that arose around medical technologies of cutting human flesh, this essay traces multiple parallel narratives on acceptable use and representation of the human body (Congolese or Belgian) beyond its medical assignation.

    The case histories, autopsy protocols, and histological specimens from 11 patients who had died from HIV-associated tuberculosis and 15 patients died from progressive disseminated tuberculosis and caseous pneumonia in the absence of HIV infection (a control group). In all the study patients, the morphology of the lung and peripheral and intrathoracic lymph nodes was examined at the early (2B) and late (4B-5) stages of HV infection (Groups 1 and 2, respectively). Group 1 patients had died from caseous pneumonia. Their morphology of tuberculosis differed little from that in the control group. Group 2 was marked by a predominance of disseminated tuberculosis with extensive exudative necrotic lesions in the lung, lymph nodes, and other organs in the presence of reduced lymphoid tissue and in the absence of a limited epitheloid cell reaction.

    A woman in her mid-forties had repeated vomiting and diarrhoea accompanied by muscle weakness soon after she started taking seven different diet pills imported from Thailand. After she had taken the pills for 8 days, respiratory depression progressed rapidly to arrest. Blood tests at the Emergency Department showed severe hypokalaemia with metabolic alkalosis. We diagnosed that she had developed pseudo-Bartter syndrome from the findings based on ionic abnormalities and high renin and aldosterone levels, and hyperplasia of the juxtaglomerular apparatus. A postmortem blood analysis indicated subtherapeutic levels of furosemide. We concluded that the patient died from pseudo-Bartter syndrome, which was triggered by chronic self-administration of furosemide and aggravated by the diet pills. This is the first pseudo-Bartter syndrome autopsy report to show histological localisation of calcification in the kidneys. PMID:21686346

    This study explores suicide in relation to perfectionism among individuals who died by suicide with no history of treatment in mental health care or of suicide attempts. The study is part of an ongoing psychological autopsy study (PA-study). It aimed to produce a phenomenological understanding of the dynamics/processes from perfectionism to suicide among 6 men aged 22 to 58. Interpretative Phenomenological Analysis (IPA) was used to analyze the interview data of 41 key informants. Based on the informants' narratives, it seemed that perfectionism left these men less able to cope with their (self-perceived) inability to meet their high expectations. Four themes emerged from analysis: 1) striving for success; 2) fear of failure; 3) keeping up the façade; and 4) rigidity. The results may be important in the prevention of nonclinical suicides, a group that is particularly difficult to identify, especially if the deceased have been regarded as very successful in many areas.

    Chronic lymphocytic leukemia (CLL) is a lymphoid neoplasia with the B immunophenotype, which corresponds to the leukemic form of lymphocytic lymphoma. This entity is characterized, in most cases, by immunosuppression due to impaired function of immune cells, hypogammaglobulinemia, bone marrow infiltration, and immune dysfunction due to the neoplasia and the chemotherapy, when prescribed. We describe the case of a 63-year-old woman with a previous diagnosis of advanced CLL, refractory to treatment, who presented respiratory failure at the emergency department and died soon after hospital admission. The autopsy examination showed a large retroperitoneal mass compressing large vessels and abdominal and pelvic organs; generalized lymphadenopathy; and liver, spleen, bone marrow, heart and kidney infiltration. A Gram-negative bacilli bronchopneumonia with diffuse alveolar damage was detected, which was likely to be the immediate cause of death. PMID:27284536

    The aim of this study was to evaluate the impact of conventional radiology on the assessment of causes of death of human beings after a building collapse and to establish whether the radiographic approach is useful and justifiable. Eight victims of a building collapse were subjected to autopsy, toxicology and radiographic examinations of the entire body. The autopsy findings, classified into three groups according to the New Injury Severity Score (NISS), were compared with radiographic findings. The death of the three individuals in group 1 was ascribed to mechanical asphyxia. Costal fractures, pneumothorax and subcutaneous emphysema were detected in one case only. The three individuals in group 2 died of mechanical asphyxia associated with cerebral injuries in all cases, abdominal injuries in two and cardiac injuries in one. Plain films showed skull fracture in one case, air within the cardiac chambers in another and diaphragmatic injuries in the third. The two individuals in group 3 died of injuries not compatible with life at the cardiac and abdominal level in both cases and at the cerebral level in one. Radiography showed multiple fractures of the cranium associated with diaphragmatic injuries in one case only. No significant pleuropulmonary radiographic findings were detected in any of the eight victims. Paralytic ileus, identified in all patients, is not strictly correlated to abdominal injuries. Skeletal injuries were all confirmed at conventional radiography. Conventional radiography allows for the overall assessment of skeletal injuries. Radiographic findings provide limited information about the causes of death, whereas findings related to the concomitant causes of death are more frequent. Conventional radiography should be considered inadequate, especially if the potential of the modern software tools available on current computed tomography and magnetic resonance images is considered.

    Each year, 1.2 million people die worldwide as a result of motor-vehicle accidents (MVA), representing a tremendous burden to healthcare. The aim of this study was to define the prevalence of coronary disease and its possible role in motor-vehicle accidents. We examined consecutive cases of non-hospital sudden death autopsies in the area of West Quebec during the period of 2002-2006, and we focused on those victims of MVA. Severe coronary artery disease (CAD) was defined as a narrowing of ≥ 75% of a cross-sectional area or the presence of acute plaque events in major epicardial coronary arteries. From a total cohort of 1260 autopsies, MVA were responsible for 123 deaths, 100 of whom were men and 23 were women. Significant CAD was documented in approximately 37% of these cases. In individuals older than 60 years, the prevalence of significant CAD and ischemia were 86.2% and 19.8%, respectively. A percentage of 40% of the coronary patients showed erratic driving before the accident, as observed by witnesses. Statistical analysis showed that an individual affected by CAD has 9% probability of suffering a motor-vehicle accident. The prevalence of severe CAD and acute myocardial ischemia is very high among individuals who have suffered a MVA. Our data suggest the hypothesis that acute CAD could be the cause of accidents in a large group of the drivers affected by coronary disease. For these reasons CAD could be investigated in drivers above 50 years old, as a possible preventive measure and determinant of individual risk stratification. Copyright © 2011 Elsevier Ireland Ltd.

    Maternal mortality is a major health problem concentrated in resource-poor regions. Accurate data on its causes using rigorous methods is lacking, but is essential to guide policy-makers and health professionals to reduce this intolerable burden. The aim of this study was to accurately describe the causes of maternal death in order to contribute to its reduction, in one of the regions of the world with the highest maternal mortality ratios. We conducted a prospective study between October 2002 and December 2004 on the causes of maternal death in a tertiary-level referral hospital in Maputo, Mozambique, using complete autopsies with histological examination. HIV detection was done by virologic and serologic tests, and malaria was diagnosed by histological and parasitological examination. During 26 mo there were 179 maternal deaths, of which 139 (77.6%) had a complete autopsy and formed the basis of this analysis. Of those with test results, 65 women (52.8%) were HIV-positive. Obstetric complications accounted for 38.2% of deaths; haemorrhage was the most frequent cause (16.6%). Nonobstetric conditions accounted for 56.1% of deaths; HIV/AIDS, pyogenic bronchopneumonia, severe malaria, and pyogenic meningitis were the most common causes (12.9%, 12.2%, 10.1% and 7.2% respectively). Mycobacterial infection was found in 12 (8.6%) maternal deaths. In this tertiary hospital in Mozambique, infectious diseases accounted for at least half of all maternal deaths, even though effective treatment is available for the four leading causes, HIV/AIDS, pyogenic bronchopneumonia, severe malaria, and pyogenic meningitis. These observations highlight the need to implement effective and available prevention tools, such as intermittent preventive treatment and insecticide-treated bed-nets for malaria, antiretroviral drugs for HIV/AIDS, or vaccines and effective antibiotics for pneumococcal and meningococcal diseases. Deaths due to obstetric causes represent a failure of health

    We report an autopsy case of dementia lacking distinctive histology (DLDH) showing semantic dementia. At age 47, a Japanese man developed aspontaneity, followed by semantic dementia a few months after the onset. Thereafter he developed disinhibition and the language disturbance, which progressed transcortical sensory aphasia and terminally mixed transcortical aphasia. At age 48, about 10 months after the disease onset, neurological examination revealed frontal signs and hyperreflexia in the four extremities and 4 months later, the patient presented with mild rigidity in the right upper and lower extremities. At age 49, 1 year and 8 months after the onset of the disease, he could not walk by himself. At age 50, 2 years and 8 months after the onset, he died of pneumonia. The brain weighed 1350 g. Macroscopically, atrophy of the frontal lobes and temporal lobes, predominant in the left, was evident. The caudate nucleus was severely atrophic, in addition to the depigmentation of the substantia nigra. Neuronal loss and astrocytosis was obvious in the cerebral cortex, prominently in the frontotemporal lobes, amygdala, caudate nucleus, putamen, pallidum, thalamus, and substantia nigra. In the caudate nucleus, prominent neuronal loss with fibrillary gliosis was obvious. Senile plaques, neurofibrillary tangles, Pick bodies, astrocytic plaques, and tufted astrocytes were not found by Gallyas and tau staining. Ubiquitin-immunoreactive intracytoplasmic inclusions were not encountered in the hippocampal dentate gyrus and superficial layers in the frontotemporal cortex. On the basis of meticulous perusal of the literature, we believe that our case is the first autopsy case of DLDH reported in Japan.

    Invasive mycoses are pre-eminent causes of morbidity and mortality in the allogeneic stem cell transplant setting. In spite of novel diagnostic modalities, the timely and specific identification of invasive mycoses still remains challenging. We analyzed the case history of 97 consecutive patients receiving 103 allogeneic stem cell transplants between January 2003 and October 2006 performed by a single team at 2 transplant centers in Budapest, Hungary. All patients with febrile neutropenia not responding to broad-spectrum antibacterial therapy received amphotericin B deoxycholate empirically. In cases of proven or probable invasive aspergillosis, intravenous voriconazole was instituted. Patients who failed to improve on initial therapy were treated with an antifungal combination, while responders were switched to oral voriconazole. A total of 38 patients died following allografting. Both centers had an autopsy rate of 100% due to central health care regulations. An infectious cause of death could be identified in 15 cases, invasive fungal disease being the most prevalent and accounting for 10 fatalities. Six patients died of invasive aspergillosis, while invasive candidiasis and mucormycosis led to a fatal outcome in 2 cases each. Despite the regular use of galactomannan antigen detections and imaging, an ante mortem diagnosis of proven/probable invasive fungal disease could only be established in 4 of 10 autopsy-verified cases (aspergillosis: 3, candidiasis: 1, mucormycosis: 0). In the remaining 6 patients, deep mycoses were missed clinically and were revealed only by postmortem histology. Present diagnostic and therapeutic strategies still seem to be suboptimal for the management of invasive fungal diseases in the high-risk allogeneic stem cell transplant population.

    Full Text Available Abstract Background Results of previous autopsy studies indicate that increased hepatic iron stores or hepatic iron overload is common in African Americans dying in hospitals, but there are no reports of hepatic iron content in other cohorts of African Americans. Methods We investigated the prevalence of heavy liver iron deposition in African American adults. Using established histochemical criteria, we graded Perls' acid ferrocyanide-reactive iron in the hepatocytes and Kupffer cells of 341 consecutive African American adults who were autopsied in the coroner/medical examiner office. Heavy staining was defined as grade 3 or 4 hepatocyte iron or grade 3 Kupffer cell iron. Results There were 254 men and 85 women (mean age ± 1 SD: 44 ± 13 y vs. 48 ± 14 y, respectively; p = 0.0255; gender was unstated or unknown in two subjects. Approximately one-third of subjects died of natural causes. Heavy staining was observed in 10.2% of men and 4.7% of women. 23 subjects had heavy hepatocyte staining only, six had heavy Kupffer cell staining only, and one had a mixed pattern of heavy staining. 15 subjects had histories of chronic alcoholism; three had heavy staining confined to hepatocytes. We analyzed the relationships of three continuous variables (age at death in years, hepatocyte iron grade, Kupffer cell iron grade and two categorical variables (sex, cause of death (natural and non-natural causes in all 341 subjects using a correlation matrix with Bonferroni correction. This revealed two positive correlations: hepatocyte with Kupffer cell iron grades (p Conclusions The present results confirm and extend previous observations that heavy liver iron staining is relatively common in African Americans. The pertinence of these observations to genetic and acquired causes of iron overload in African Americans is discussed.

    2015-02-01

    Full Text Available Background: Sudden cardiac death (SCD is a sudden unexpected event, from a cardiac cause, that occurs in less than one hour after the symptoms onset, in a person without any previous condition that would seem fatal or who was seen without any symptoms 24 hours before found dead. Although it is a relatively frequent event, there are only few reliable data in underdeveloped countries. Objective: We aimed to describe the features of SCD in Ribeirão Preto, Brazil (600,000 residents according to Coroners’ Office autopsy reports. Methods: We retrospectively reviewed 4501 autopsy reports between 2006 and 2010, to identify cases of SCD. Specific cause of death as well as demographic information, date, location and time of the event, comorbidities and whether cardiopulmonary resuscitation (CPR was attempted were collected. Results: We identified 899 cases of SCD (20%; the rate was 30/100000 residents per year. The vast majority of cases of SCD involved a coronary artery disease (CAD (64% and occurred in men (67%, between the 6th and the 7th decades of life. Most events occurred during the morning in the home setting (53.3% and CPR was attempted in almost half of victims (49.7%. The most prevalent comorbidity was systemic hypertension (57.3%. Chagas’ disease was present in 49 cases (5.5%. Conclusion: The majority of victims of SCD were men, in their sixties and seventies and the main cause of death was CAD. Chagas’ disease, an important public health problem in Latin America, was found in about 5.5% of the cases.

    The aim of our study was to determine the frequency and nature of testicular and paratesticular lesions in forensic autopsies. A retrospective study was carried out on 495 adult male cases that underwent forensic autopsy from January 2008 to December 2011 in our Department. For each case, the following parameters were reported: age, body mass index, nature of testicular and paratesticular lesions, associated lesions in external genitalia, testicle weight, cause of death, manner of death, resuscitation attempts and prior medical history. Mean age of the studied population was 47.8 years (range 18-96). Mean body mass index was 25.3 kg/m(2) (range 15-46.2). Testicular lesions and/or paratesticular were found in 16.4% of the cases (n = 81). The most frequent lesions were, respectively, testicular atrophy (n = 38) and trauma (n = 28). In three cases showing traumatic lesions, associated traumatic lesions were found in external genitalia. Most frequent cause of death was blunt trauma (19.9% of the cases). Manner of death most frequently associated with testicular trauma was, respectively, road traffic accident (n = 11) and suicidal fall (n = 6). Mean testicular weight was, respectively, 17.9 g for the right and 20.8 g for the left (range 2-38). Atrophy was associated with testicular weight less than 10 g. A significant association between testicular atrophy and age was found, the risk of atrophy increasing quite linearly with age. No significant statistical link between prior medical history and testicular pathology was found. There was also no influence of body mass index. Resuscitation attempts were not statistically associated with testicular traumatic lesions.

    A man in his 40s was found unconscious on a sofa in a communal residence for people with various disabilities. He appeared to have drunk 800 ml of undiluted citric acid from a commercial plastic bottle. The instructions on the label of the beverage specified that the beverage be diluted 20- to 30-fold before consumption. The patient was admitted to an emergency hospital with severe metabolic acidosis (pH, 6.70; HCO3(-), 3.6 mEq/L) and a low ionized calcium level (0.73 mmol/L). Although ionized calcium and catecholamines were continuously administered intravenously to correct the acidosis, the state of acidemia and low blood pressure did not improve, and he died 20 h later. Citric acid concentrations in the patient's serum drawn shortly after treatment in the hospital and from the heart at autopsy were 80.6 mg/ml and 39.8 mg/dl, respectively (normal range: 1.3-2.6 mg/dl). Autopsy revealed black discoloration of the mucosal surface of the esophagus. Microscopically, degenerated epithelium and neutrophilic infiltration in the muscle layer were observed. In daily life, drinking a large amount of concentrated citric acid beverage is rare as a cause of lethal poisoning. However, persons with mental disorders such as dementia may mistakenly drink detergent or concentrated fluids, as in our case. Family members or facility staff in the home or nursing facility must bear in mind that they should not leave such bottles in places where they are easily accessible to mentally handicapped persons.

    2006-11-01

    Full Text Available Abstract Background MeduMobile was a project to develop and evaluate learning scenarios for medical students and teachers by use of video communication and notebooks. Its core part was assigned to various medical routines, conferences or meetings such as doctor-patient bedside conversation. These were filmed by video teams and broadcasted live via the WLAN of the Charité campus to course participating students. One type of the learning arrangements was the autopsy conference as an on-call scenario. Materials and methods The MeduMobile project consisted of two main compartments: the regular seminar event which took place every week or month, and the on-call event. For an on-call event the students were informed two hours before the lesson's start. A mobile video team organised the video conference via a specific MeduMobile seminar system. This software offered the students to log. The MeduMobile seminar system is based on the Windows operating system and realises an extended video communication via WLAN. Thirteen access points were implemented at the Charité Campus Virchow Klinikum and Campus Mitte. A questionnaire was developed to investigate in the response and learning effect of the mobile seminar system. Results During the MeduMobile project 42 video conferences with (cumulative 145 participating students took place. Four autopsy conferences could be organised as on-call scenarios within this project. A prospective, not randomised follow-up study was included 25 students of the 1st – 6th clinical semester. According to the answers, professional reasoning, professional performance, sustainability, and the complexity were broadly accepted by the students. Discussion In principle, the MeduMobile realised an interdisciplinary case presentation using video conference and web page. The evaluation indicates a high acception of such complex case presentation with multidisciplinary settings. The use of the notebooks in mobile learning enables an

    We investigated the trends in dementia over the past 29 years in the town of Hisayama, Japan using 1266 autopsy specimens. The Hisayama study is a prospective cohort study of lifestyle-related diseases that was started in 1961. Clinical examination of dementia was started in 1985 with five detailed cross-sectional assessments conducted in 1985, 1992, 1998, 2005 and 2012. To examine the trends in dementia, we divided the 1266 autopsy samples into five groups according to the year of death: I (1986-1991, 257 cases), II (1992-1997, 268 cases), III (1998-2004, 318 cases), IV (2005-2011, 296 cases) and V (2012-2014, 127 cases). The prevalence of all-cause dementia significantly increased over time (28.4% in group I, 22.4% in group II, 32.1% in group III, 30.1% in group IV, 51.2% in group V; P for trend dementia of the NFT type (SD-NFT) in recent years was notable. Vascular dementia was the most common type of dementia in men prior to 2004; however, its prevalence decreased over time. Our study revealed that tauopathies, including AD and SD-NFT, significantly increased in the aged Japanese population over the course of this study. The neuritic plaque pathology of AD was associated with metabolic disorders such as insulin resistance and abnormal lipid metabolism, whereas the risk factors for tau pathology remain unclear. Although aging is considered one of the important risk factors accelerating tau pathology, there could be other risk factors associated with lifestyle diseases.

    In this study, it was aimed to analyze the cases of traffic accident related deaths, buried without performing autopsy, in order to increase awareness of the physicians about declaration liability of forensic cases and also emphasize the declaration of the forensic case and autopsy importance. In the First Specialization Board of Council of Forensic Medicine, 542 cases of death, reported between the years 2004-2008, who were involved in traffic accidents and buried without an autopsy performed, were evaluated retrospectively. It was found that 69.4% of the cases (n=376) were males, whereas %30.6 (n=166) were females; mean age was 58.5±20.9 (range, 3-98 years). Age 61 and above was the most frequent age group with 301 cases (55.5%). Of the cases, 336 (62.0%) had died in hospital, 241 (44.5%) had died in 1-12 months following the accident and medico-legal corpse examination was performed only in 123 (22.9%) cases. Three hundred fourty-four (63.5%) of the cases were not reported as forensic cases and death certificate was signed by any physician other than medical examiner without being declared as a legal case. According to the decisions of Board, since an autopsy was not duly performed, the cause of death could not be determined for 95 cases (17.5%) and for 57 cases (10.5%), it was not possible to determine whether there was causality between the accident and death. Our findings emphasize the importance of declaration of forensic cases and performing autopsy in time in traffic accident victims.

    Bernese mountain dogs are reported to have a shorter life expectancy than other breeds. A major reason for this has been assigned to a high tumour prevalence, especially of histiocytic sarcoma. The efforts made by the breeding clubs to improve the longevity with the help of genetic tests and breeding value estimations are impeded by insufficiently reliable diagnoses regarding the cause of death. The current standard for post mortem examination in animals is performance of an autopsy. In human forensic medicine, imaging modalities, such as computed tomography and magnetic resonance imaging, are used with increasing frequency as a complement to autopsy. The present study investigates, whether post mortem computed tomography in combination with core needle biopsy is able to provide a definitive diagnosis of histiocytic sarcoma. For this purpose we have analysed the results of post mortem computed tomography and core needle biopsy in eleven Bernese mountain dogs. In the subsequent autopsy, every dog had a definitive diagnosis of histiocytic sarcoma, based on immunohistochemistry. Computed tomography revealed space-occupying lesions in all dogs. Lesion detection by post mortem computed tomography was similar to lesion detection in autopsy for lung tissue (9 cases in computed tomography / 8 cases in autopsy), thoracic lymph nodes (9/8), spleen (6/7), kidney (2/2) and bone (3/3). Hepatic nodules, however, were difficult to detect with our scanning protocol (2/7). Histology of the core needle biopsies provided definitive diagnoses of histiocytic sarcoma in ten dogs, including confirmation by immunohistochemistry in six dogs. The biopsy samples of the remaining dog did not contain any identifiable neoplastic cells. Autolysis was the main reason for uncertain histological diagnoses. Post mortem computed tomography is a fast and effective method for the detection of lesions suspicious for histiocytic sarcoma in pulmonary, thoracic lymphatic, splenic, osseous and renal tissue

    As science and technology developed, the tools of humans developed from humans’hands, to mechanical and digital technologies. The tools influ-ence almost everything in the humans’world, so does vernacular. The digital vernacular could be understood as using digital technology to vernacular; the digital means technologies. It also could be understood as doing vernacular in a digital way;the digital means data and information, in other words it can be seeking truth from facts. Define digital vernacular is not only what is digital vernacular, but also about how to do the digital vernacular and what kind of attitude we should hold to-ward the digital vernacular.

    There were large number of virtuous woman images in vernacular short novels of the Ming and Qing Dynasties. We can see the gender characteristics of female chastity view in feudal period and dominant effect on female thoughts and behaviors from the images, especially those typical images. Taking virtuous women images in vernacular short novels of the Ming and Qing Dynasties as an example, the chastity view which Chinese ancient women understood reflects some features: the chastity is women's "duty", keeping chastity is bidirectional and chastity is important than filial piety and utilitarian.%明清拟话本小说中存在着大量的贞节烈女形象,从这些形象,尤其是那些典型形象身上,可以透视出封建时代女性贞节观的性别特点及其对女性思想行为的支配作用。以明清拟话本小说中的贞节烈女形象为例,中国古代女性视角所理解的贞节观体现出了贞节是女人的“本分内事”、守贞具有双向性和贞节重于孝道、实利等特点。

    Full Text Available Abstract Background The process of data collection and the methods used to assign the cause of death vary significantly among different verbal autopsy protocols, but there are few data to describe the consequences of the choices made. The aim of this study was to objectively define the impact of the format of data presented to physician reviewers on the cause-specific mortality fractions defined by a verbal autopsy-based mortality-surveillance system. Methods Verbal autopsies were done by primary health care workers for all deaths between October 2006 and September 2007 in a community in rural Andhra Pradesh, India (total population about 180,162. Each questionnaire had a structured section, composed of a series of check boxes, and a free-text section, in which a narrative description of the events leading to death was recorded. For each death, a physician coder was presented first with one section and then the other in random order with a 20- to 40-day interval between. A cause of death was recorded for each data format at the level of ICD 10 chapter headings or else the death was documented as unclassified. After another 20- to 40-day interval, both the structured and free-text sections of the questionnaire were presented together and an index cause of death was assigned. Results In all, 1,407 verbal autopsies were available for analysis, representing 94% of all deaths recorded in the population that year. An index cause of death was assigned using the combined data for 1,190 with the other 217 remaining unclassified. The observed cause-specific mortality fractions were the same regardless of whether the structured, free-text or combined data sources were used. At the individual level, the assignments made using the structured format matched the index in 1,012 (72% of cases with a kappa statistic of 0.66. For the free-text format, the corresponding figures were 989 (70% and 0.64. Conclusions The format of the verbal autopsy data used to assign

    Currently there are two main sources of mortality data with cause of death assignments in China. Both sources-the Ministry of Health-Vital Registration system and the Chinese Disease Surveillance Point system-present their own challenges. A new approach to cause of death assignment is a smartphone-based shortened version of a verbal autopsy survey. This study evaluates the feasibility and acceptability of this new method conducted by township health care providers (THP) and village doctors (VD) in rural China, where a large proportion of deaths occur in homes and cause of death data are inaccurate or lacking. The Population Health Metrics Research Consortium mobile phone-based shortened verbal autopsy questionnaire was made available on an Android system-based application, and cause of death was derived using the Tariff method (Tariff 2.0); we called this set of tools "msVA." msVA was administered to relatives of the deceased by six THPs and six VDs in 24 villages located in six townships of Luquan County, Hebei Province, China. Subsequently, interviews were conducted among 12 interviewers, 12 randomly selected respondents, and five study staff to assess the feasibility and acceptability of using msVA for mortality data collection. Between July 2013 and August 2013, 268 deaths took place in the study villages. Among the 268 deaths, 227 VAs were completed (nine refusals, 31 migrations and one loss of data due to breakdown of the smartphone). The average time for a VA interview was 21.5 ± 3.4 min (20.1 ± 3.5 min for THP and 23.2 ± 4.1 min for VD). Both THPs and VDs could be successful interviewers; the latter needed more training but had more willingness to implement msVA in the future. The interviews revealed that both interviewers and relatives of the deceased found msVA to be feasible, acceptable, and more desirable than traditional methods. The cost of conducting a new VA was $8.87 per death. Conduction of msVA by VDs in their own villages was

    Full Text Available BACKGROUND: Maternal mortality is a major health problem concentrated in resource-poor regions. Accurate data on its causes using rigorous methods is lacking, but is essential to guide policy-makers and health professionals to reduce this intolerable burden. The aim of this study was to accurately describe the causes of maternal death in order to contribute to its reduction, in one of the regions of the world with the highest maternal mortality ratios. METHODS AND FINDINGS: We conducted a prospective study between October 2002 and December 2004 on the causes of maternal death in a tertiary-level referral hospital in Maputo, Mozambique, using complete autopsies with histological examination. HIV detection was done by virologic and serologic tests, and malaria was diagnosed by histological and parasitological examination. During 26 mo there were 179 maternal deaths, of which 139 (77.6% had a complete autopsy and formed the basis of this analysis. Of those with test results, 65 women (52.8% were HIV-positive. Obstetric complications accounted for 38.2% of deaths; haemorrhage was the most frequent cause (16.6%. Nonobstetric conditions accounted for 56.1% of deaths; HIV/AIDS, pyogenic bronchopneumonia, severe malaria, and pyogenic meningitis were the most common causes (12.9%, 12.2%, 10.1% and 7.2% respectively. Mycobacterial infection was found in 12 (8.6% maternal deaths. CONCLUSIONS: In this tertiary hospital in Mozambique, infectious diseases accounted for at least half of all maternal deaths, even though effective treatment is available for the four leading causes, HIV/AIDS, pyogenic bronchopneumonia, severe malaria, and pyogenic meningitis. These observations highlight the need to implement effective and available prevention tools, such as intermittent preventive treatment and insecticide-treated bed-nets for malaria, antiretroviral drugs for HIV/AIDS, or vaccines and effective antibiotics for pneumococcal and meningococcal diseases.

    Graphical abstract: -- Highlights: •Postmortem swelling of the brain is a typical finding on PMCT and occurs concomitant with potential antemortem or agonal brain edema. •Cerebral edema despite normal postmortem swelling is indicated by narrowed temporal horns and symmetrical herniation of the cerebral tonsils on PMCT. •Cases with intoxication or asphyxia demonstrated higher deviations of the attenuation between white and gray matter (>20 Hounsfield Units) and a ratio >1.58 between the gray and white matter. •The Hounsfield measurements of the white and gray matter help to determine the cause of death in cases of intoxication or asphyxia. -- Abstract: Purpose: The purpose of this study was to compare postmortem computed tomography with forensic autopsy regarding their diagnostic reliability of differentiating between pre-existing cerebral edema and physiological postmortem brain swelling. Materials and methods: The study collective included a total of 109 cases (n = 109/200, 83 male, 26 female, mean age: 53.2 years) and were retrospectively evaluated for the following parameters (as related to the distinct age groups and causes of death): tonsillar herniation, the width of the outer and inner cerebrospinal fluid spaces and the radiodensity measurements (in Hounsfield Units) of the gray and white matter. The results were compared with the findings of subsequent autopsies as the gold standard for diagnosing cerebral edema. p-Values <0.05 were considered statistically significant. Results: Cerebellar edema (despite normal postmortem swelling) can be reliably assessed using postmortem computed tomography and is indicated by narrowed temporal horns and symmetrical herniation of the cerebellar tonsils (p < 0.001). There was a significant difference (p < 0.001) between intoxication (or asphyxia) and all other causes of death; the former causes demonstrated higher deviations of the attenuation between white and gray matter (>20 Hounsfield Units), and the gray to

    To retrospectively study the pathology of HIV seropositive in forensic autopsies. Three hundred thirty five HIV seropositive cases, selected from 7,387 forensic postmortem inquests by law, were studied in Ramathibodi hospital between 2000 and 2010. The study topics were sex, age, cause of death, manner of death, and pathological features. Autopsies were done in 67 cases. The pathological features were classified into five groups, (a) HIV disease with infectious and parasitic diseases, (b) HIV disease with malignant neoplasms, (c) HIV disease with other specified diseases, (d) HIV disease with other conditions, and (e) HIV disease with unspecified pathology. The average prevalence of HIV seropositive cases was 4.5%. The peak was 10.0% in 2001 and gradually decreased until 1.8% in 2010. The ratio of male:female was 4:1. The most manner of death was natural death (83.6%). In unnatural death cases, the most frequently method was suicide by hanging. The prevalence of HIV group (a) to group (e) were 56.7%, 6.0%, 3.0%, 17.9%, and 16.4%, respectively. Pulmonary tuberculosis is the most common found in group (a) with frequency of 28.4%. Kaposi's sarcoma of skin, coronary atherosclerosis, and fatty change of liver were frequently observed in HIV group (b) to group (d), respectively. The pathology showed multiple pathological features in each group, i.e., group (a) pulmonary tuberculosis, pneumonia, disseminated fungal infection, brain abscess, and meningitis, group (b) Kaposi's sarcoma of skin and acute lymphoblastic leukemia, group (c) coronary atherosclerosis, chronic pyelonephritis, gastritis, and cirrhosis of the liver, and group (d) cardiomegaly, fatty change of liver; pulmonary edema, and splenomegaly. HIV disease causes pathology of various organs. The severities vary from severe to asymptomatic disease. Five pathological patterns of HIV were established in this study that showed interesting topics, i.e., pulmonary tuberculosis was the most frequent and occurred (28

    Computed tomography (CT) has been used routinely at the Department of Forensic Medicine, University of Copenhagen since 2002. A retrospective study was performed in order to correlate CT-scan based diagnoses of cranial and cerebral lesions with macroscopic autopsy diagnoses in 56 cases. The CT-scans were performed by a forensic pathologist. They were obtained by using two different CT-scan protocols. The results showed correct skull fracture diagnoses in 34/56 cases. Fractures were diagnosed partially (9) or missed totally (13) on CT-images in 22 cases. The agreement for fracture diagnoses of the anterior, medial and posterior cranial fossae was 20%, 52% and 60%, respectively. Fractures involving bilateral bones were diagnosed correctly more frequently. The diagnostic agreement regarding brain injuries varied from 0% to 79%. Both the autopsy-reports and CT-scan descriptions need to be standardized in order to secure more exact comparisons in the future.

    The number of tattooed people in Germany has constantly grown over the past few years. The present study deals with the question if this social trend can be seen in foren- sic autopsy cases as well. In a retrospective study, forensic autopsy cases of two periods (1990-1994 and 2010-2014) have been reviewed and statistically analyzed. Comparison of the two periods revealed a significant increase in tattooed individuals, especially in the female subgroup. Between 2010 and 2014, 14.2 % of the deceased showed tattoos. There are significant differences in the frequency and localization of tattoos dependent on age and sex. About 50 % of the tattooed deceased showed tattoos on body sites that are visible for other persons in everyday life. The resulting value of tattoos for the purpose of identifying unknown bodies is discussed and illustrated.

    A sudden unexpected death is considered one type of medico-legal death in Thailand. In some studies, it comprises up to 50-60% of all medico-legal deaths. In this retrospective study, data were collected from 1,460 cases of sudden unexpected deaths, 39.9% of all deaths in which a medico-legal autopsy had been carried out. The study was conducted over a 5-year period from January 2003 to December 2007. There were 1,009 males and 451 females (M:F ratio = 2.2:1). The mean age was 55.3+/-0.98 years. The peak age group was the 46-60 years accounting for 28.2% of cases. The most common cause of death in all age groups was coronary atherosclerosis. Understanding epidemiological autopsy data is vital for determining the characteristics of the population involved.

    The questions of cause and manner of death are the most pressing ones in any forensic investigation. Traditionally, autopsy is the means to provide answers to these questions and despite the increasing use of CT and MR in the post-mortem setting, imaging has usually been an adjunct to forensic autopsy. Here we describe a case where post-mortem CT and MR were performed instead of autopsy, at the request of the responsible public prosecutor. The forensic conclusions derived from imaging, including cause and manner of death were accepted by the legal authorities, thereby setting precedence for future cases. This case represents a landmark in forensic medicine and is another step toward the full realization of minimally invasive forensic autopsy.

    Full Text Available The MIT Libraries, the San Diego Supercomputer Center, and the University of California San Diego Libraries are conducting the PLEDGE Project to determine the set of policies that affect operational digital preservation archives and to develop standardized means of recording and enforcing them using rules engines. This has the potential to allow for automated assessment of “trustworthiness” of digital preservation archives. We are also evaluating the completeness of other efforts to define policies for digital preservation such as the RLG/NARA Trusted Digital Repository checklist and the PREMIS metadata schema. We present our results to date.

    2009-10-01

    Full Text Available Computed tomography (CT is now the primary diagnostic method for head trauma because of its ability to demonstrate the nature, extent, sites, and multiplicity of brain injuries. Although there have been numerous reports on the CT findings of most types of intracranial injury, the findings in brainstem injury have not been well described. This study aimed at comparing the autopsy findings of brainstem in head trauma in comparison with CT scan results. Two hundred patients with head trauma, who expired after a period of time of hospitalization, were assessed in a diagnostic value study. Brain stem involvement was determined by autopsy as well as CT scanning of the brain during their hospitalization. The results of the two methods were compared with each other, emphasizing on the type and location of probable lesions in the brain stem. Considering the autopsy as the method of the choice, sensitivity, specificity, positive predictive value (PPV and negative predictive value (NPV of CT scan in brain stem lesions of patients with head trauma were calculated. The effect of primary cause of head trauma, survival time and Glasgow Coma Scale (GCS were evaluated, as well. Brain stem lesions were detected in 39 (19.5% patients in autopsy. However, CT scan revealed brain stem lesions in 23(11.5% cases. The sensitivity, specificity, PPV and NPV of CT scan was 59%, 100%, 100% and 91% respectively. The most common lesions of the brain stem region were as contusion of pons (8.5%, medulla (5% and midbrain (4.5%. There were 6 (3% cases of ponto-medullary junction tearing and 1 (0.5% case of cervico-medullary junction tearing. CT scan is a specific method of evaluating patients with probable brain stem injuries after head trauma, but low sensitivity limits its efficacy. Our results are in conformity with the reports in the literature.

    The incidence of cancer of the pancreatoduodenal organs (the pancreas, major duodenal papilla, extrahepatic bile ducts, duodenum) is reported according to the autopsy findings obtained at two clinical hospitals (provincial and municipal) of Donetsk city during the period from 1957 to 1973. There is a tendency to the increased mortality due to cancer of the localization concerned against the background of the reduced total mortality.

  16. University of Pittsburgh Medical Center remains tracker: A novel application for tracking decedents and improving the autopsy workflow

    Directory of Open Access Journals (Sweden)

    Matthew A Smith

    2011-01-01

    Full Text Available All hospitals deal with patient deaths. Multiple departments and personnel must be coordinated to ensure that decedents are safely managed. Prior to 2004, at the University of Pittsburgh Medical Center (UPMC, when a patient passed away, the process of alerting involved personnel, transporting the decedent, and tracking the completion of clinical documents was cumbersome and inefficient. In order to address these concerns, UPMC Remains Tracker, a web-based application, was developed to improve the efficiency and simplify the logistics related to the management of patient deaths. The UPMC Information Services division developed UPMC Remains Tracker, an application that tracks decedents′ locations, documentation status, and autopsy status within UPMC hospitals. We assessed qualitative improvement in decedent remains tracking, decedent paperwork management, and staff satisfaction and compliance. UPMC Remains Tracker improved the process of tracking decedents′ locations, identifying involved personnel, monitoring autopsy requests, and determining the availability for funeral home transportation. Resident satisfaction with UPMC Remains Tracker was generally positive and scored as "Improved efficiency" and makes identifying and tracking decedents "Much easier". Additionally, the nursing staff reacted favorably to the application. A retrospective review of the use of the application in the management of 100 decedents demonstrated a 93% compliance rate. Among the cases requiring an autopsy, there was a 90% compliance rate. The process of tracking decedents, their paperwork, involved staff, and decedent autopsy status is often inefficient. This assessment suggests that incorporating new technologies such as UPMC Remains Tracker into the management of hospital deaths provides accurate tracking of remains, streamlines the administrative tasks associated with deaths, and increases nursing and resident satisfaction and compliance.

    There is an urgent need to identify tools able to provide reliable information on the cause of death in low-income regions, since current methods (verbal autopsy, clinical records, and complete autopsies) are either inaccurate, not feasible, or poorly accepted. We aimed to compare the performance of a standardized minimally invasive autopsy (MIA) approach with that of the gold standard, the complete diagnostic autopsy (CDA), in a series of adults who died at Maputo Central Hospital in Mozambique. In this observational study, coupled MIAs and CDAs were performed in 112 deceased patients. The MIA analyses were done blindly, without knowledge of the clinical data or the results of the CDA. We compared the MIA diagnosis with the CDA diagnosis of cause of death. CDA diagnoses comprised infectious diseases (80; 71.4%), malignant tumors (16; 14.3%), and other diseases, including non-infectious cardiovascular, gastrointestinal, kidney, and lung diseases (16; 14.3%). A MIA diagnosis was obtained in 100/112 (89.2%) cases. The overall concordance between the MIA diagnosis and CDA diagnosis was 75.9% (85/112). The concordance was higher for infectious diseases and malignant tumors (63/80 [78.8%] and 13/16 [81.3%], respectively) than for other diseases (9/16; 56.2%). The specific microorganisms causing death were identified in the MIA in 62/74 (83.8%) of the infectious disease deaths with a recognized cause. The main limitation of the analysis is that both the MIA and the CDA include some degree of expert subjective interpretation. A simple MIA procedure can identify the cause of death in many adult deaths in Mozambique. This tool could have a major role in improving the understanding and surveillance of causes of death in areas where infectious diseases are a common cause of mortality.

    Fatal Lyme carditis caused by the spirochete Borrelia burgdorferi rarely is identified. Here, we describe the pathologic, immunohistochemical, and molecular findings of five case patients. These sudden cardiac deaths associated with Lyme carditis occurred from late summer to fall, ages ranged from young adult to late 40s, and four patients were men. Autopsy tissue samples were evaluated by light microscopy, Warthin-Starry stain, immunohistochemistry, and PCR for B. burgdorferi, and immunohistochemistry for complement components C4d and C9, CD3, CD79a, and decorin. Post-mortem blood was tested by serology. Interstitial lymphocytic pancarditis in a relatively characteristic road map distribution was present in all cases. Cardiomyocyte necrosis was minimal, T cells outnumbered B cells, plasma cells were prominent, and mild fibrosis was present. Spirochetes in the cardiac interstitium associated with collagen fibers and co-localized with decorin. Rare spirochetes were seen in the leptomeninges of two cases by immunohistochemistry. Spirochetes were not seen in other organs examined, and joint tissue was not available for evaluation. Although rare, sudden cardiac death caused by Lyme disease might be an under-recognized entity and is characterized by pancarditis and marked tropism of spirochetes for cardiac tissues.

    Caffeine has long been recognized as an addictive substance that causes autonomic nerve effect, and is known to increase catecholamine secretion from the adrenal glands. In recent years, the risk of ingesting toxic levels of caffeine has increased because of the easy availability of analgesics, CNS (Central Nervous System) stimulant medicine and dietary supplements at shops, health stores and through online purchases. We report the death of a young female resulting from the ingestion for suicide of an online purchased sleepiness-preventing medicine containing caffeine. The autopsy findings included pulmonary edema and congestion plus cutaneous emphysema. The stomach contents included a dark-brown viscous fluid without tablet or food residue. Toxicological examination revealed the presence of caffeine in the right heart blood (154.2 μg/mL) and stomach contents (197.5 μg/mL) (lethal blood level, >80 μg/mL). The highest caffeine content was in the bile (852.3 μg/mL). Biochemical findings showed that catecholamine concentration in the peripheral blood in the iliac vein was elevated. Immunostaining of catecholamine was weak in the adrenal medulla. We recommend highlighting the toxicity risk of ingesting substances with a high caffeine concentration, and we propose that caffeine concentrations should be included in the comprehensive routine forensic toxicological tests for all cases.

    Bathtub drownings are a significant cause of mortality in the pediatric population. Infants and preambulatory children are disproportionately affected, and several studies have suggested that preventative campaigns have been ineffective in the prevention of such deaths. To obtain a better understanding of the factors associated with bathtub drownings, a retrospective review of autopsy records over a 20-year period (1984-2003) was performed. Eighteen consecutive cases of bathtub drownings were identified in 8 males and 10 females (ratio, 0.8; P = 0.6374). The age ranged from 6 months to 70 months (mean, 17 months; median, 11 months), and most cases occurred in infants aged 12 months or less (72%). Males tended to be older than females (mean, 23 months versus 11 months; P = 0.1889). Associated factors included inadequate adult supervision (89%), cobathing (39%), the use of infant bath seats (17%), and coexistent medical disorders predisposing the infant or child to the drowning episode (17%). The pathologic findings included a frothy exudate (28%), pleural effusion (28%), and increased lung weight (61%). All toxicologic samples submitted for analysis were negative. The present study highlights the factors associated with bathtub drownings and may aid in the prevention of such deaths in the pediatric population.

    Lung diseases are frequently observed in individuals infected with HIV. The aim of this study was to identify infectious agents in the lungs in the autopsied individuals with AIDS performed between march 1990 and july 2000 at the school of medicine (Uberaba- Brazil), using histochemical and immunohistochemical techniques. Analysis was made on lungs obtained from 40 individuals with AIDS. Infectious agents were observed in 34 (85%) cases of the 40 analyzed. Regarding fungis, Pneumocystis carinii was found in 8 (19.1%)cases; Cryptococcus sp in 4 (9.5%)cases, Histoplasma sp in 2 (4.8%)cases and Candida sp in 1 (2.4%)case. Association of Pneumocystis carinii, Citomegalovirus and Cryptococcus sp, was observed in one case, and in another, the association of CMV, and Toxoplasma gondii. There were 5 cases with Candida sp, CMV and Pneumocystis carinii associated with bacteria. In conclusion, this study shows that following bacterial agents fungi were the second most common infectious agents in post mortem examination of the lungs from patients with AIDS, being Pneumocystis carinii the most prevalent.

    Full Text Available Introduction: Chronic pancreatitis and liver disease are two conditions that commonly co-exist in chronic alcoholics with variable incidences. Aim: To evaluate frequency pancreatitis in patients with a history of chronic alcohol abuse. Materials and Methods: A total of 390 autopsies over 11 year′s period were included in the study. Gross and microscopic assessment of liver and pancreas were performed. Available clinical and laboratory parameters were recorded. Results: Age ranged from 22 to 65 years with a mean age of 45.32 years. All 390 consecutive patients included in the study were males. Majority of the patients had primarily presented with alcohol related liver diseases whereas few had presented with features of pancreatitis. Micronodular cirrhosis was present in 292 cases. Features of chronic pancreatitis were observed in 42 cases and 8 of these cases had associated changes of acute hemorrhagic pancreatitis. Prevalence of pancreatitis was more in cirrhotics as compared to non-cirrhotics, and acute pancreatitis was mostly seen in non-cirrhotics. Dominant pattern of fibrosis was perilobular followed by periductal, intralobular and diffuse. Conclusion: Chronic pancreatitis as evidence by the presence of parenchymal fibrosis was more frequently observed in alcoholic cirrhosis cases than that in non-cirrhotic alcoholic liver disease, thereby suggesting common underlying pathobiology in the development of fibrosis in liver as well as in pancreas.

  4. Polycyclic Aromatic Hydrocarbon Residues in Serum Samples of Autopsied Individuals from Tennessee

    2014-12-01

    Full Text Available This study reports the concentrations of Polycyclic Aromatic Hydrocarbons (PAHs in human blood sera samples (n = 650 obtained at autopsy from individuals who died of drug abuse, alcohol toxicity, homicide, suicide and other unknown causes. The analyzed samples from decedents revealed the presence of PAHs of which B(aP was the most predominant one, followed by benzo(bfluoranthene and benzo(kfluoranthene. The other PAHs detected sporadically and measured were benzo(g,h,iperylene, acenaphthene, anthracene, phenanthrene, and fluoranthene The mean concentrations of PAHs were greater in the twenties to fifties age groups compared to others. The PAH residue levels detected were high in African Americans compared to Caucasians, Asians, and Hispanics. It appears that environmental exposure, dietary intake and in some cases occupational exposure may have contributed to the PAH body burden. While the PAH residue concentrations measured fall within the range of those reported for healthy adults elsewhere, in isolated cases, the concentrations detected were high, calling the need for a reduction in PAH emissions and human biomonitoring studies for purposes of risk assessment.

    The article analyzes the quality and consistency of a semi-structured interview script, adapted for the study on suicide among elderly people, and presents the psychological and psychosocial autopsy method, which is the result of application of this instrument. The objective is to demonstrate how the in-depth interview and subsequent data organization and analyses were tested and improved by a network of researchers from eight regions in Brazil. Evaluation of the method was conducted before and after the application of the instruments to collect, systematize and analyze the data. This methodology was applied in 51 cases of elderly people who committed suicide in ten Brazilian municipalities. The study did more than just collect data with scientific rigor, since it also verified the consistency of the instrument used and the applicability of the method. The improved script and the instructions of how to apply and analyze it are thus presented here. The results reveal the rigor and credibility of this methodological approach tested and qualified by a multidisciplinary and inter-institutional procedure.

  6. The importance of microbiological testing for establishing cause of death in 42 forensic autopsies.

    Microorganisms have always been one of the great challenges of humankind, being responsible for both high morbidity and mortality throughout history. In a forensic setting microbiological information will always be difficult to interpret due to lack of antemortem information and changes in flora postmortem. With this study we aim to review the use of microbiological procedures at our forensic institute. In a retrospective study including 42 autopsies performed at our Institute, where microbiological test had been applied, analyses were made with regard to: type of microbiological tests performed, microorganisms found, histological findings, antemortem information, C-reactive protein measurement and cause of death. Fiftyone different microorganisms were found distributed among 37 cases, bacteria being the most abundant. Nineteen of the cases were classified as having a microbiological related cause of death. C-reactive protein levels were raised in 14 cases of the 19 cases, histological findings either supported or were a decisive factor for the classification of microbiologically related cause of death in 14 cases. As a multitude of abundant microorganisms are able to cause infection under the right circumstances, all findings should be compared to anamnestic antemortem information, before conclusions are drawn. A definite list of true pathogens is nearly impossible to compile.

    This article describes the homicide pattern in Penang Island, Malaysia over a three-year period (2007-2009). 65 homicide autopsies were performed at the Department of Forensic Medicine, Penang Hospital over the study period. The homicide rates ranged from 0.01 to 0.09/1000 population, the highest being in the Indian ethnic group. The majority (37%) of victims were in the 20-39 years age group. The male: female ratio was 3:1. The majority of deaths were caused by blunt instruments (46%), followed by stab/slash wounds (25%) and asphyxiation (12%). 63% of homicides occurred in areas served by the police stations at Jalan Patani (23.1%), Sg. Nibong (16.9%), Central (12.3%) and Bayan Lepas (10.9%). 56 (86%) victims were brought in dead to the hospital, while 9 (14%) died after admission. Most (39%) incidences occurred in the morning. The methods of homicide were different from Kuala Lumpur, another highly urbanised area of Malaysia.

    Congenital diaphragmatic hernia is a congenital malformation of the diaphragm, resulting in the herniation of the abdominal organs into the thoracic cavity. The most common types of congenital diaphragmatic hernia are Bochdalek hernia (postero-lateral hernia), Morgagni hernia (anterior defect), and diaphragm eventration (abnormal displacement of part or all of an otherwise intact diaphragm into the chest cavity). Congenital diaphragmatic hernia is a life-threatening pathology in infants, and a major cause of death due to pulmonary hypoplasia and pulmonary hypertension. We present a fatal case of congenital diaphragmatic hernia in a newborn. At the autopsy, a central defect of the diaphragm was found, 8 × 5 cm in size, that led to a herniation of the small intestine, the right lobe of the liver, and the right adrenal gland into the thorax. An esophageal atresia was associated with the congenital diaphragmatic hernia. The lungs showed severe hypoplasia and atelectasia. Physicians should pay attention to a prenatal diagnosis of congenital diaphragmatic hernia in order to prevent newborn fatalities.

Radiological patterns of the upper lung were considered as mostly emphysema, but pathological observation revealed significant interstitial fibrosis of usual interstitial pneumonia as a major pathology. The patient eventually developed acute exacerbation of background interstitial pneumonia. Careful radiological and pathological correlation of the current case indicates that regions with distal acinar emphysema on computed tomography image may possess histologically marked dense fibrosis of lethal interstitial pneumonia.

    Lung and heart sections from 33 drug addicts submitted for medico-legal autopsy at the Institute of Forensic Medicine in Copenhagen were studied together with tissue sections from 20 'normal' persons. In the drug addict cases focal bleedings in lung tissue were found in 94%, signs of earlier bleedings, haemosiderin containing histiocytes, were seen in 91%, and focal fibrosis in 46%. The bleeding episodes may be due to hypoxia in connection with heroin intake. In 94% of the drug addicts birefringent material in lung tissue was demonstrated, in 58% in granulomas and giant cells, in 27% in giant cells only and in 9% in isolated histiocytes. The material was localized in the wall of pulmonar arteries and/or in the interstitial tissue, undoubtedly depending on the duration of the abuse. In 18% angiothrombosis was seen, in all cases granulomas/giant cells were observed in the wall of the vessel concerned. The results indicate periodical intravenous injection of dissolved tablets in addition to heroin. Histological signs of pulmonary hypertension were not seen, possibly due to the fact that abuse of central stimulants is very rare in Denmark. Regarding heart alterations no significant differences were demonstrated between drug addicts and controls. The only note-worthy finding was focal infiltration of lymphocytes in the atrio-ventricular bundle in two drug addicts, the meaning of which is uncertain.

    Autopsy findings of 652 fetuses whose parents or one parent were exposed to the Atomic Bomb (F[sub 1]) and 115 fetuses which had one or two grandparents exposed (F[sub 2]) were compared with that of 8570 fetuses whose parents were not exposed (control). The F[sub 1] fetuses have been collected since 1963 and F[sub 2] fetuses since 1971 voluntarily in Hiroshima. The findings were classified according to the types of delivery and to the distances away from the hypocenter where the parents and grandparents were exposed. Many normal cases in the group of artificial abortions and many malformations and pathological findings in the group of spontaneous abortions were found in both groups of F[sub 1] and F[sub 2]. The malformations were cardiovascular, central nervous and urogenital system, quantitatively in that order, in both groups of F[sub 1] and F[sub 2]. Although there were a few cases of cystic kidney and chondrodystrophy which belong to autosomal dominant and osteogenesis imperfecta which belong to autosomal recessive, these cases were not correlated with the distance. Most cases of malformation which belong to the multifactorial inheritance were found in each organ. No peculiar malformation was found in the groups of F[sub 1] and F[sub 2]. (author).

    Dementia with Lewy bodies (DLB) is characterized by preserved whole brain and medial temporal lobe volumes compared with Alzheimer's disease dementia (AD) on magnetic resonance imaging. However, frequently coexistent AD-type pathology may influence the pattern of regional brain atrophy rates in DLB patients. We investigated the pattern and magnitude of the atrophy rates from 2 serial MRIs in autopsy-confirmed DLB patients (n = 20) and mixed DLB/AD patients (n = 22), compared with AD (n = 30) and elderly nondemented control subjects (n = 15), followed antemortem. DLB patients without significant AD-type pathology were characterized by lower global and regional rates of atrophy, similar to control subjects. The mixed DLB/AD patients displayed greater atrophy rates in the whole brain, temporoparietal cortices, hippocampus and amygdala, and ventricle expansion, similar to AD patients. In the DLB and DLB/AD patients, the atrophy rates correlated with Braak neurofibrillary tangle stage, cognitive decline, and progression of motor symptoms. Global and regional atrophy rates are associated with AD-type pathology in DLB, and these rates can be used as biomarkers of AD progression in patients with LB pathology.

    Suicide is one of the ten leading causes of death in the world, accounting for more than 400,000 deaths annually. The pattern of suicide and the incidence of suicide vary from country to country. Cultural, religious and social values play some role in suicide. Compared to the West and some of the countries in the Asian region the incidence of suicide is low in Malaysia. A three-year retrospective study of all the autopsies performed at the University Hospital, Kuala Lumpur was analysed and the cases that were definitely determined as suicides were further studied. 48.8% of all suicides were ethnic Indians though Indians formed only 8% of the Malaysian population. 38.1% of suicides were Chinese who formed 26% of the population while only 3.6% were Malays, who formed 59% of the population. The preferred methods of suicide were poisoning and hanging. The majority were in the age group 20-40 yr. The study may have missed some cases that would have been wrongly concluded as accidental deaths and a few others where the police would have released the bodies without postmortem examinations.

  14. Renal tubular dysgenesis with hypocalvaria and ileocecal valve agenesis: an autopsy report

    2012-12-01

    Full Text Available Renal tubular dysgenesis (RTD is a rare, lethal, autosomal recessive disorder characterized by non-differentiation of the renal proximal convoluted tubules, resulting in oligohydramnios. It is usually diagnosed in the second trimester of pregnancy, following the oligohydramnios sequence, pulmonary hypoplasia and hypocalvaria. The prognosis is poor, and death usually occurs in utero or within the first few days of life. The pathogenesis of RTD is associated with the perinatal use of drugs, such as angiotensin- converting enzyme inhibitors, angiotensin II receptor antagonists, and anti- inflammatory drugs, as well as with fetal transfusion syndrome, genetic mutations in the pathway of the renin-angiotensin system pathway, cocaine snorting, or other pathological mechanisms that reduce renal blood flow. Here, we report the autopsy of a neonate born to consanguineous parents at 38 weeks of gestation, with RTD, decreased amniotic fluid, oligohydramnios sequence, hypocalvaria, pulmonary hypoplasia, and ileocecal valve agenesis. To our knowledge, the latter has never been reported associated with RTD.

    Full Text Available A 57-year-old diabetic male, presented with altered sensorium since 2 days. He had a history of weight loss, loss of appetite, intermittent low-grade fever of 6 months duration. He had been administered empirical antituberculous therapy some months ago with no alleviation of symptoms. On examination, he was asthenic, normotensive, and anemic with hepatosplenomegaly. Ultra-sonography abdomen revealed bilateral enlarged adrenals with hepatosplenomegaly. Clinically impression was of tuberculosis disseminated malignancy. He expired within 2 days of admission. At autopsy, both the adrenals were markedly enlarged showing extensive areas of necrosis on the cut surface. Histology showed them to be brimming with colonies of yeast-forms of Histoplasma capsulatum. These organisms were also seen in the spleen, lungs and kidneys. The patient had died of septicemia following disseminated histoplasmosis that was, unfortunately, not diagnosed during his life. Histoplasmosis is amenable to treatment with Amphotericin B. Prompt diagnosis and treatment could have helped in salvaging this patient.

    Objective To compare the characteristics of suicides in the four main demographic groups: urban males, urban females,rural males and rural females in order to help clarify the demographic pattern of suicides in China. Methods A detailed psychological autopsy survey instrument was independently administered to 895 suicide victims in family members and close associates from 23 geographically representative locations from around the country. Results Pesticide ingestion accounted for 58% (519) of all suicides and 61% (318/519) of deaths were due to unsuccessful medical resuscitation. A substantial proportion (37%) of suicide victims did not have a mental illness. Among the 563 victims with mental illness, only 13%(76/563) received psychiatric treatment. Compared to other demographic groups, young rural females who died from suicide had the highest rate of pesticide ingestion (79%), the lowest prevalence of mental illness (39%), and the highest acute stress from precipitating life events just prior to the suicide. Conclusion Many suicides in China are impulsive acts of deliberate self-harm following acute interpersonal crises. Prevention of suicides in China must focus on improving awareness of psychological problems, improving mental health services, providing alternative social support networks for managing acute interpersonal conflicts, limiting access to pesticides, and improving the resuscitation skills of primary care providers.

    The unique case of a 50-year-old known alcoholic whose corpse was exhumed 27 years after death is reported. The man apparently committed suicide by hanging, but many years later the case was questioned and homicide-linked to a long-lasting serial killer case-was suspected. Thus, the corpse was exhumed, and at the autopsy it was found to be naturally mummified. This fact permitted the analysis of body tissues with the aim to investigate the persistence of ethanol conjugates in the biological material 27 years after death. Fragments of liver and kidney, a blood clot, and a hair strand were collected and submitted to liquid chromatography tandem mass spectrometry analysis. Ethyl glucuronide (EtG) and ethyl sulfate (EtS) were identified and quantified in the liver, the kidney, and the blood clot. Hair analysis was found to be severely affected by ion suppression even after solid phase extraction. Consequently, EtG was identified in all hair segments (0-3 cm, 3-6 cm, and 6-10 cm), but no reliable quantification could be carried out. In summary, our findings demonstrate that, notwithstanding the expected conjugate degradation, EtG and EtS can be indicative of ante-mortem use of alcohol even many years after death.

    Full Text Available Primary angiitis of CNS(PACNS or granulomatous angiitis of CNS is a rare inflammatory disease of small blood vessels mostly confined to the CNS. The clinical and pathological features of 3 autopsied cases are described. Clinically all the three PACNS patients were young males, age ranging from 19 to 31 years. All presented with varied neurological manifestations. There was no evidence of systemic disease in any of the cases. The ESR was normal and CSF analysis showed chronic meningitic pattern. The cerebral angiogram in one case was normal and the CT scan done in another case showed multiple intracerebral haematoma due to vasculitis. Brain biopsy was not done. Diagnosis was made at post-mortem examination. Histology showed characteristic but variable degree of granulomatous and non-granulomatous angiitis of small vessels. Venulitis with parenchymal haemorrhages was the predominant feature and in one case phlebitis with thrombosis was noted. Since the disease responds to steroids and immunosuppressive therapy, establishing antemortem diagnosis is important. In view of the association of angiitis of CNS with bacteria and viral infections, their role in the evolution of the disease needs to be investigated.

    A morphologic evaluation was carried out on adrenal glands from 128 autopsied patients with the acquired immunodeficiency syndrome (AIDS). The adrenal gland was compromised in 99.2% of the cases, with distinct pathological features and infectious agents. Inflammatory infiltrates were observed in 99.2% of the cases with a predominance of mononuclear cells in 97.4%, affecting mainly the medulla. Necrosis, fibrosis, hemorrhages and neoplasias were observed. We also described 3 (2.3%) cases of calcification located in the adrenal gland central vein (AGCV). This is seldom mentioned in the literature. Cytomegalovirus was the most frequent infectious agent, observed in 48.4% of cases. Balamuthia mandrillaris, a free living ameba, was found in one case affecting the entire gland. We also found a nest of Trypanosoma cruzi in the musculature of the AGCV. The presence of the nest of T cruzi in AGCV may play a role in the reactivation of this infection in immunosuppressed individuals. Pathologic processes and opportunistic infections may contribute to the alterations in the adrenal gland that lead to multiple organ failure observed in terminal AIDS patients.

    This study aimed to elucidate the demographic and sleeping environmental factors associated with sudden infant death syndrome (SIDS) in Korea. The autopsy reports of all SIDS cases reported to the National Forensic Service and Seoul National University College of Medicine between 1996 and 2008 were reviewed for data collection and analysis to identify the risk factors for SIDS. Analysis of the 355 SIDS cases reported within the study period revealed that of the 168 (47.3%) cases for which sleeping position before death had been reported, 75 (44.7%) cases had occurred after placement in prone or side position. Of the 204 (57.5%) cases for which bed-sharing situation had been reported, 121 (59.3%) deaths had occurred during bed-sharing, of which 54 (44.6%) infants were under 3 months of age, a significantly younger age than that of the non-bed-sharing cases (P = 0.0279). Analysis of the results indicated no tendency toward an increase or decrease in the use of a prone or side position. Rather, there was a statistically significant increasing trend for bed-sharing over the study period (OR, 1.087; 95% CI, 1.004-1.177; P = 0.04). These findings indicate the need for nationwide educational programs promoting a safe sleeping environment to enhance SIDS prevention.

    We report the case of 2-year-old girl who died of precursor B-cell acute lymphoblastic leukaemia (ALL), the most common cancer in children. She had no remarkable medical history. She was transferred to a hospital because of respiratory distress and died 4 hours after arrival. Two weeks before death, she had a fever of 39 degrees C, which subsided after the administration of a naturopathic herbal remedy. She developed jaundice 1 week before death, and her condition worsened on the day of death. Laboratory test results on admission showed a markedly elevated white blood cell count. Accordingly, the cause of death was suspected to be acute leukaemia. Forensic autopsy revealed the cause of death to be precursor B-cell ALL. With advancements in medical technology, the 5-year survival rate of children with ALL is nearly 90%. However, in this case, the deceased's parents preferred complementary and alternative medicine (i.e., naturopathy) to evidence-based medicine and had not taken her to a hospital for a medical check-up or immunisation since she was an infant. Thus, if she had received routine medical care, she would have a more than 60% chance of being alive 5 years after diagnosis. Therefore, we conclude that the parents should be accused of medical neglect regardless of their motives.

    1992-09-01

    Full Text Available Eleven out of 36 autopsied cases of Wernicke's encephalopathy had developed coma. None of these patients had the diagnosis during life. There were six men and five women with ages ranging from 36 to 50 years (mean 36.6. Seven of these patients were heavy drinkers, three exhibited signs of severe malnutrition, whereas one was being evaluated for a disseminated gastric cancer and one was in treatment of hyperemesis gravidarum. Two patients were brought to the hospital after found unconscious at home. Neuropatholo-gical examination disclosed gross changes in the mammillary bodies in eight cases and microscopic changes in all cases. In one case there was atrophy of the anterior superior part of the vermis. Petechial hemorrhages were observed particularly in the walls of the third ventricle. Microscopically there were in addition to hemorrhages, glial proliferation, endothelial hypertrophy and necrosis of nerve cells and myelin. Central pontine myelmolysis was observed in one case. Wernicke's encephalopathy is a clinically underdiagnosed condition. Coma may mask its classical clinical picture or even be the sole manifestation. Although coma points to a poor outlook it may be reversed by thiamine administration. Any patient with Coma of unknown etiology should be given parenteral thiamine.

    Pulmonary edema is a common finding in fatal methamphetamine intoxication. However, the underlying mechanism remains poorly understood. This study investigated the molecular pathology of alveolar damage involving pulmonary edema in forensic autopsy cases. Seven candidate reference genes (RPL13A, YWHAZ, GUSB, SDHA, GAPDH, B2M, and ACTB) were evaluated in the lung by the geNorm module in qBase(plus) software. RPL13A, YWHAZ, and GUSB were identified as the most stable reference genes. Using these validated reference genes, intrapulmonary mRNA expressions of matrix metalloproteinases (MMPs), intercellular adhesion molecule-1 (ICAM-1), claudin-5 (CLDN-5), and aquaporins (AQPs) were examined. Relative mRNA quantification using TaqMan real-time PCR assay demonstrated higher expressions of all markers except for AQP-5 in fatal METH intoxication cases. These findings suggested alveolar damage and compensatory response in fatal METH intoxication cases. Systematic analysis of gene expressions using real-time qPCR is a useful tool in forensic death investigation.

    Previous studies have examined the prevalence of psychological strains among various suicide populations. However, it is still unexamined whether psychological strains can predict suicide intent directly. We planned to explore the prevalence of psychological strains and analyze the relationship between psychological strains and suicide intent among Chinese rural young suicides. Psychological autopsy method was used to investigate the environmental and other factors of rural young suicides. Psychological strains were identified from in-depth interviews by the proxy informants of each suicide. The first 8 items of Beck's Suicidal Intention Scale (SIS) were used to estimate the suicide intent. Results showed that 96.6% of the suicides had at least one type of strain, and those suicides who had more strains tended to score higher on the suicide intent scale. The study further supports that suicide intent can be predicted by psychological strains in Chinese rural young suicides. The scanning of psychological strains can be used for suicide prevention in Chinese rural young suicides. © The Author(s) 2015.

    It has been hypothesised that the very nature of the game predisposes elite cricketers to higher rates of suicide. We aim to estimate the suicide rate of male Test cricketers and to determine the reasons for suicide. The suicide rate in male Test cricketers was determined. A psychological autopsy was conducted using published biographical data. Twenty suicides amongst 2794 male Test cricketers from 1877 to 2014 yielded a suicide rate of 715.4 per 100,000 for that period. Health, financial and relationship issues were prominent; depression and alcohol misuse were common. Most suicides in Test cricketers occurred post-retirement in mid to late life with similar correlates to those found in the general male population. The idiosyncrasies of cricket are unlikely to contribute to suicide; however, the post-retirement welfare of Test cricketers should remain a focus of concern and the greater supports available to contemporary Test cricketers needs to extend beyond retirement. © The Royal Australian and New Zealand College of Psychiatrists 2016.

    Full Text Available Mitral valve prolapse (MVP is usually asymptomatic, but can be associated with complications such as infective endocarditis, mitral regurgitation, thromboembolism and sudden cardiac death. It has been very rarely reported to occur in association with other valvular involvement. A 55-year-old male patient was brought dead and at autopsy the mitral valve orifice was stenotic and the leaflets were enlarged, myxoid and bulging suggestive of MVP and chordae tendinae were thickened, stretched and elongated. Similar changes were seen in the tricuspid valve. The pulmonary and aortic valves also showed myxomatous degeneration of their cusps. Myxomatous degeneration is the most common cause of MVP and it can be associated with involvement of the other valves. Concomitant involvement of the aortic valve has been reported, however it is very rare and simultaneous involvement of the pulmonary valve has not been reported in the literature so far. We report a case of MVP associated with myxomatous degeneration of the tricuspid, pulmonary and aortic valves.

    Dementia with Lewy bodies (DLB) is characterized by preserved whole brain and medial temporal lobe volumes compared to Alzheimer’s disease dementia (AD) on MRI. However, frequently coexistent AD-type pathology may influence the pattern of regional brain atrophy rates in DLB patients. We investigated the pattern and magnitude of the atrophy rates from two serial MRIs in autopsy-confirmed DLB (n=20) and mixed DLB/AD patients (n=22), compared to AD (n=30) and elderly non-demented controls (n=15), followed antemortem. DLB patients without significant AD-type pathology were characterized by lower global and regional rates of atrophy, similar to controls. The mixed DLB/AD patients displayed greater rates in the whole brain, temporo-parietal cortices, hippocampus and amygdala, and ventricle expansion, similar to AD patients. In the DLB and DLB/AD patients, the atrophy rates correlated with Braak neurofibrillary tangle stage, cognitive decline and progression of motor symptoms. Global and regional atrophy rates are associated with AD-type pathology in DLB, and can be used as biomarkers of AD progression in patients with LB pathology. PMID:25128280

    Fetal and infant autopsy yields information regarding cause of death and the risk of recurrence, and it provides closure for parents. A significant number of perinatal evaluations are performed by general practice pathologists or trainees, who often find them time-consuming and/or intimidating. We sought to create a program that would enable pathologists to conduct these examinations with greater ease and to produce reliable, informative reports. We developed software that automatically generates a set of expected anthropometric and organ weight ranges by gestational age (GA)/postnatal age (PA) and a correlative table with the GA/PA that best matches the observed anthropometry. The program highlights measurement and organ weight discrepancies, enabling users to identify abnormalities. Furthermore, a Web page provides options for exporting and saving the data. Pathology residents utilized the program to determine ease of usage and benefits. The average time using conventional methods (ie, reference books and Internet sites) was compared to the average time using our Web page. Average time for novice and experienced residents using conventional methods was 26.7 minutes and 15 minutes, respectively. Using the Web page program, these times were reduced to an average of 3.2 minutes (P software allows data exportation to reports and data storage for future analysis. Finalization of our software to enable usage by both university and private practice groups is in progress.

    We report an autopsy case of a male welder in his thirties who was found dead in an exploded truck cabin. The roof, windows and doors of the cabin had been blown up to 50 metres away. An oxygen cylinder and an acetylene cylinder, both unexploded, were found in the back of the truck. The deceased was lying on the driver's seat. His entire body was burnt, carbonised and partially skeletonised. There was a small amount of soot in his oesophagus and stomach and a large volume of bloody fluid in the trachea and bronchi. There was an extensive haemorrhage in the posterior thoracic wall. No drugs were detected in the blood. Hardly any carbon monoxide and combustion-related gases were detected in the blood, therefore he was not considered to have died from the fire. Acetylene was detected in his blood (21.5 microg/ml in the femoral vein blood) and urine (7.49 microg/ml), with marked haemorrhaging in his back. We therefore concluded that the victim died because of an acetylene explosion in the cabin and also that this was a suicide.

    Sudden death in the young is a devastating complication of inherited heart disorders. Finding the precise cause of death is important, but it is often unresolved after postmortem investigation. The addition of postmortem genetic testing, i.e., the molecular autopsy, can identify additional causes of death. We evaluated DNA extracted from formalin-fixed paraffin-embedded postmortem tissue for exome sequencing-based molecular autopsy after sudden death in the young. We collected clinical and postmortem information from patients with sudden death. Exome sequencing was performed on DNA extracted from fixed postmortem tissue. Variants relevant to the cause of death were sought. Five patients with genetically unresolved sudden death were recruited. DNA extracted from fixed postmortem tissue was degraded. Exome sequencing achieved 20-fold coverage of at least 82% of coding regions. A threefold excess of singleton variants was found in the exome sequencing data of one patient. We found a de novo SCN1A frameshift variant in a patient with sudden unexpected death in epilepsy and a LMNA nonsense variant in a patient with dilated cardiomyopathy. DNA extracted from fixed postmortem tissue is applicable to exome sequencing-based molecular autopsy. Fixed postmortem tissues are an untapped resource for exome-based studies of rare causes of sudden death.Genet Med advance online publication 23 March 2017.

    Neurocysticercosis is a serious public health problem in several countries of Asia, Africa and Latin America. The objective of the present study is to present autopsy findings of neurocysticercosis in the Pathology Division of the University Hospital, Medical School of Ribeirão Preto, University of São Paulo, from 1992 to 1997. Neurocysticercosis was detected in 38 (1.5%) of 2522 autopsies. In twenty two (57.9%) of these, the diagnosis was made post-mortem, while 16 (42.1%) had a previous diagnosis of cysticercosis based on laboratory and imaging studies. Reviewing the medical records, we found that 21 patients (55.2%) were neurologically asymptomatic, while the various clinical manifestations in the others were in accordance with the literature. The high frequency of asymptomatic individuals detected only post-mortem indicates the importance of autopsies as an additional source of data to consolidate the compulsory notification of cysticercosis. Considering the results of this study, the new coefficient of prevalence of cysticercosis in Ribeirão Preto is 67 cases/100,000 inhabitants.

    AIMS: To corroborate the findings of in utero magnetic resonance imaging (MRI) with autopsy and post-mortem MRI in cases of known or suspected central nervous system (CNS) abnormalities on ultrasound and to compare the diagnostic accuracy of ante-natal ultrasound and in utero MRI. METHODS: Twelve pregnant women, whose foetuses had suspected central nervous system abnormalities underwent in utero MRI. The foetuses were imaged using MRi before autopsy. The data were used to evaluate the diagnostic accuracy of in utero MRI when compared with a reference standard of autopsy and post-mortem MRI in 10 cases and post-mortem MRI alone in two cases. RESULTS: The diagnostic accuracy of antenatal ultrasound and in utero MRI in correctly characterizing brain and spine abnormalities were 42 and 100%, respectively. CONCLUSION: In utero MRI provides a useful adjuvant to antenatal ultrasound when assessing CNS abnormalities by providing more accurate anatomical information. Post-mortem MRI assists the diagnosis of macroscopic structural abnormalities.

    Since traffic accidents are an important problem in forensic medicine, there is a constant search for new solutions to help with an investigation process in such cases. In recent years there was a rapid development of post-mortem imaging techniques, especially post-mortem computed tomography (PMCT). In our work we concentrated on a potential advantage of PMCT in cases of motorcycle accident fatalities. The results of forensic autopsy were compared with combined results of the autopsy and PMCT to check in which areas use of these two techniques gives statistically important increase in number of findings. The hypothesis was confirmed in case of pneumothorax and fractures of skull, spine, clavicle, scapula, lower leg bones. As for majority of other bone fractures locations and brain injures there were single cases with pathologies visible only in PMCT, but too few to reach expected level of p-value. In case of injuries of solid organs and soft tissues statistical analysis did not confirmed any advantage of unenhanced PMCT use. On the whole it has been shown that PMCT used as an adjunct to forensic autopsy can cause an increase in information about vitally important regions in case of motorcycle accident fatalities.

    Hemopericardium is a common finding at autopsy, but it may represent a challenge for the forensic pathologist when the etiopathologi-cal relationship in causing death is requested. Hemopericardium and cardiac tamponade can be evaluated in living people using radiological techniques, in particular computer tomography (CT). Only a few studies are reported in literature involving post-mortem (PM) cases, where PMCT imaging has been used in order to investigate acute hemopericardium, and they have shown a good accuracy of this technique. Here we report a case involving a 70-year-old white male found dead on the beach, with a medical history of hepatitis C and chronic hypertension with a poor pharmacological response. A PMCT was performed about 3 h after the discovery of the body. The PMCT examination showed an intrapericardial aortic dissection associated to a periaortic hematoma, a sickle-shaped intramural hematoma, a false lumen, and a hemop-ericardium consisting in fluid and clotted blood. In this case, the PMCT was able to identify the cause of death, even though a traditional autopsy was required to confirm the radiological findings. PMCT is a reliable technique, which in chosen cases, can be performed without the need for a traditional autopsy to be carried out.

Verbal autopsy is used to captured TB death cases happened  at home. The sample of " true” TB and "non” TB tests were selected from three gold standard hospital in Metro city. Verbal autopsy was conducted by well trained nurses/midwives from Puskesmas, interviewing  families having the death cases. Two reviewers  set up diagnoses based on the results of the VA. A referee team would decide the final cause of death (COD if the two diagnoses made by these two reviewers were unmatched. To avoid bias in this study, the blind technique was applied. The result of validation test shows out of 95 cases picked out from the three hospitals, only 65 of them were available for interview, 16 were defined to be TB cases and the other 49 cases were non TB, based as gold standard. There were 13 cases of well matched diagnoses between VA result and gold standard with Sensitivity value of 81 per cent (13 per 16. Twenty one death cases were defined TB through VA, the Positive Predictive Value was then 62 per cent (13 per 21. Those result is not much difference with the other place. The quality to determine the cause of death should be improved based on the /CD-10 mortality coding.   Key words: Validation, verbal autopsy, tuberculosis

    Comparison of clinical and autopsy findings of the cases studied between 1984 and 1988, were made at the Department of Pathology of the Instituto Nacional de la Nutricion Salvador Zubiran in Mexico City. The goal was to determine the accuracy of clinical diagnoses. The total number of cases was 429. A decreasing number of autopsies as a function of time was observed. Thus, in 1985, 34.65% of the deaths was autopsied, whereas in 1988, the number dropped to 21.16%, overall mean of 27.31%. In 229 autopsies (53.8%), 353 findings of clinical significance were found; of these, 86 were in the main diagnoses and 267 in the causes of death. There were 171 overdiagnoses with therapeutic implications, 38 in the main diagnoses and 133 in the causes of death. Overdiagnoses and underdiagnoses were most common in infectious diseases, followed by respiratory and digestive diseases, while endocrinologic and rheumatologic diseases had the highest diagnostic concordance. It was also found that the diagnostic accuracy did not improve with time of hospitalization. A brief analyses of the probable causes of the decrease in the number of autopsies is made. It is concluded that, in spite of the great advances in clinical and technological knowledge, the high frequency of disagreements between clinical and anatomical diagnoses, indicate that autopsy continues playing a key role in the quality control of medical practice. This justifies by itself the performance of necropsies.

    The selection and writing of Jin Shu· Biographies of Virtuous Women are not out of moral values in Tang dynasty, which focuses more on praising the women who are loyal, obedient and can die to defend her chastity. However, Jin Shu·Biographies of Virtuous Women is an exception among the eight offcial historical books written by Tang government because of its descriptions of intelligent women. It’s a different phenomenon from other offcial historical books that the number of the intelligent women selected is almost the same as the number of loyal, obedient women in Jin Shu. Moreover, the descriptions of intelligent women are more perfect than writings of loyal, obedient women. There is a contradiction between Jin Shu· Biographies of Virtuous Women and the virtue of women selected in the book, seeming nonconforming to what is described in offcial historical books in Tang Dynasty. The contradiction is a result of political strategy with a purpose to embellish the behaviors of emperors of Tang dynasty, especially Emperor Li Shimin, who ordered his ministers to write the Jin Shu.%《晋书·列女传》对于女子事迹言行的选材与编撰并没有脱离唐代社会的主流价值观,其仍然以表彰妇女的节烈孝义为主。不过《晋书·列女传》对于有识鉴的才智女性的褒扬,不但表现在传主的数量上与忠贞女子最为接近,对于这类女性的描写与颂扬也远较忠贞女子丰满。《晋书·列女传》与自身所标榜的妇女节烈之德有矛盾之处,更显得与唐代官方史学对女德的看法步调不甚协调。这种不协调不是偶然,而是有着深刻的政治与史学思想的原因。

    Full Text Available Abstract Background Alcohol makes an important contribution to premature mortality in many countries in Eastern Europe, including Estonia. However, the full extent of its impact, and the mechanisms underlying it, are challenging issues to research. We describe the design and initial findings of a study aimed at investigating the association of alcohol with mortality in a large series of forensic autopsies of working-age men in Estonia. Methods 1299 male deaths aged 25-54 years were subject to forensic autopsy in 2008-2009. The routine autopsy protocol was augmented by a more systematic inspection of organs, drug testing, assay of liver enzymes and novel biomarkers of alcohol consumption (EtG, EtS and PEth, together with proxy interviews with next of kin for deaths among men who lived in or close to a major town. Results 595 augmented autopsies were performed. Of these, 66% were from external causes (26% suicide, 25% poisoning. 17% were attributed to circulatory system diseases and 7% to alcoholic liver disease. Blood alcohol concentrations (BAC of ≥ 0.2 mg/g were found for 55% of deaths. Interviews were conducted with proxy informants for 61% of the subjects who had resided in towns. Of these, 28% were reported in the previous year to have been daily or almost daily drinkers and 10% had drunk non-beverage alcohols. Blood ethanol and the liver enzyme GGT were only associated with daily drinking. However, the novel biomarkers showed a more graded response with recent consumption. In contrast, the liver enzymes AST and ALT were largely uninformative because of post-mortem changes. The presence of extremely high PEth concentrations in some samples also suggested post-mortem formation. Conclusion We have shown the feasibility of deploying an extended research protocol within the setting of routine forensic autopsies that offer scope to deepen our understanding of the alcohol-related burden of premature mortality.

    Full Text Available Abstract Background Effective implementation of child survival interventions depends on improved understanding of cultural, social, and health system factors affecting utilization of health care. Never the less, no standardized instrument exists for collecting and interpreting information on how to avert death and improve the implementation of child survival interventions. Objective To describe the methodology, development, and first results of a standard social autopsy tool for the collection of information to understand common barriers to health care, risky behaviors, and missed opportunities for health intervention in deceased children under 5 years old. Methods Under the INDEPTH Network, a social autopsy working group was formed to reach consensus around a standard social autopsy tool for neonatal and child death. The details around 434 child deaths in Iganga/Mayuge Health and Demographic Surveillance Site (HDSS in Uganda and 40 child deaths in Dodowa HDSS in Ghana were investigated over 12 to 18 months. Interviews with the caretakers of these children elicited information on what happened before death, including signs and symptoms, contact with health services, details on treatments, and details of doctors. These social autopsies were used to assess the contributions of delays in care seeking and case management to the childhood deaths. Results At least one severe symptom had been recognized prior to death in 96% of the children in Iganga/Mayuge HDSS and in 70% in Dodowa HDSS, yet 32% and 80% of children were first treated at home, respectively. Twenty percent of children in Iganga/Mayuge HDSS and 13% of children in Dodowa HDSS were never taken for care outside the home. In both countries most went to private providers. In Iganga/Mayuge HDSS the main delays were caused by inadequate case management by the health provider, while in Dodowa HDSS the main delays were in the home.

    In this article we study the digital homology groups of digital images which are based on the singular homology groups of topological spaces in algebraic topology. Specifically, we define a digitally standard $n$-simplex, a digitally singular $n$-simplex, and the digital homology groups of digital images with $k$-adjacency relations. We then construct a covariant functor from a category of digital images and digitally continuous functions to the one of abelian groups and group homomorphisms, and investigate some fundamental and interesting properties of digital homology groups of digital images, such as the digital version of the dimension axiom which is one of the Eilenberg-Steenrod axioms.

  12. Social autopsy for maternal and child deaths: a comprehensive literature review to examine the concept and the development of the method

    Directory of Open Access Journals (Sweden)

    Koffi Alain K

    2011-08-01

    Full Text Available Abstract "Social autopsy" refers to an interview process aimed at identifying social, behavioral, and health systems contributors to maternal and child deaths. It is often combined with a verbal autopsy interview to establish the biological cause of death. Two complementary purposes of social autopsy include providing population-level data to health care programmers and policymakers to utilize in developing more effective strategies for delivering maternal and child health care technologies, and increasing awareness of maternal and child death as preventable problems in order to empower communities to participate and engage health programs to increase their responsiveness and accountability. Through a comprehensive review of the literature, this paper examines the concept and development of social autopsy, focusing on the contributions of the Pathway Analysis format for child deaths and the Maternal and Perinatal Death Inquiry and Response program in India to social autopsy's success in meeting key objectives. The Pathway Analysis social autopsy format, based on the Pathway to Survival model designed to support the Integrated Management of Childhood Illness approach, was developed from 1995 to 2001 and has been utilized in studies in Asia, Africa, and Latin America. Adoption of the Pathway model has enriched the data gathered on care seeking for child illnesses and supported the development of demand- and supply-side interventions. The instrument has recently been updated to improve the assessment of neonatal deaths and is soon to be utilized in large-scale population-representative verbal/social autopsy studies in several African countries. Maternal death audit, starting with confidential inquiries into maternal deaths in Britain more than 50 years ago, is a long-accepted strategy for reducing maternal mortality. More recently, maternal social autopsy studies that supported health programming have been conducted in several developing countries

    Full Text Available Introduction. The forming of the blood vessels network configuration at the base of the brain and interconnecting of blood vessels during the embryogenesis is directly related to the phylogenetic development of the brain and brain structures. A blood vessel configuration at the brain base, in the form of a ring or a hexagon, stands in direct relation to the perfusion needs of certain parts of the brain during its primary differentiation. The aim of this paper was to determine the incidence of certain blood vessel configurations at the base of the brain and understanding their symmetry or asymmetry. Methods. Analysis of the blood vessels at the base of the brain was performed on the autopsied subjects. The object of observation was the anterior segment of the circle of Willis consisting of C1- a. carotis interna (ICA, above a. communicaus posterior (PcoA, the segment A1 a. cerebri anterior (ACA from a. carotis interna bifurcation to the a. communicans anterior (AcoA and a. communicans anterior itself, as well as the posterior segment consisting of PcoA and the segment P1 - a. cerebri posterior (PCA from the a. basilaris bifurcation to the PcoA. For the purpose of grouping the findings, the four basic configuration types of the circle of Willis were identified based on its symmetry or asymmetry. Type-A (symmetric circle of Willis, type-B (asymmetric circle of Willis' due to the unilateral hypoplastic A1-ACA; type-C (symmetric circle of Willis with bilateral symmetric changes on PcoA and type-D (asymmetric circle of Willis due to the asymmetric changes on PcoA. Results. Autopsy was performed on 56 corpses. A total of 41 (73.2% subjects were recorded with a symmetric configuration of the circle of Willis', of which 27 (48.2% subjects had type A and 14 (25% type C. The asymmetric configuration was present in 15 (26.8% subjects, of whom 9 (16% had type B and 6 (10.8% type D. The symmetric Willis group (73.2% did not have a homogeneous finding that

    Full Text Available Anthrax is a zoonotic disease that occurs naturally in wild and domestic animals but has been used by both state-sponsored programs and terrorists as a biological weapon. A Soviet industrial production facility in Sverdlovsk, USSR, proved deficient in 1979 when a plume of spores was accidentally released and resulted in one of the largest known human anthrax outbreaks. In order to understand this outbreak and others, we generated a Bacillus anthracis population genetic database based upon whole-genome analysis to identify all single-nucleotide polymorphisms (SNPs across a reference genome. Phylogenetic analysis has defined three major clades (A, B, and C, B and C being relatively rare compared to A. The A clade has numerous subclades, including a major polytomy named the trans-Eurasian (TEA group. The TEA radiation is a dominant evolutionary feature of B. anthracis, with many contemporary populations having resulted from a large spatial dispersal of spores from a single source. Two autopsy specimens from the Sverdlovsk outbreak were deep sequenced to produce draft B. anthracis genomes. This allowed the phylogenetic placement of the Sverdlovsk strain into a clade with two Asian live vaccine strains, including the Russian Tsiankovskii strain. The genome was examined for evidence of drug resistance manipulation or other genetic engineering, but none was found. The Soviet Sverdlovsk strain genome is consistent with a wild-type strain from Russia that had no evidence of genetic manipulation during its industrial production. This work provides insights into the world’s largest biological weapons program and provides an extensive B. anthracis phylogenetic reference.

    2011-12-01

    Full Text Available Abstract Background Plenty of information related to alcoholism can be found in the literature, however, the studies have mostly dealt with the predominance of male alcoholism and data related to addiction in women are desperately scarce and difficult to find. Basic demographic data focusing on the impact of acute alcohol intoxication on the circumstances of death and social behaviour in the alcohol addicted female population are needed especially in the prevention of alcohol related mortality. Methods A retrospective forensic autopsy study of all accidental deaths due to alcohol intoxication over a 12-year period was performed in order to evaluate the locations, circumstances, mechanisms and causes of death. Results A sample of 171 cases of intoxicated women who died due to blood alcohol concentration (BAC equal to or higher than 2 g/kg was selected. Among them 36.26% (62/171 of women died due to acute alcohol intoxication (AAI. We noted an increase in the number of deaths in women due to AAI from 2 in 1994 up to 5 in 2005 (an elevation of 150% between the years 1994-2005. The age structure of deaths in women due to BAC and AAI followed the Gaussian distribution with a dominant group of women aged 41-50 years (45.16% and 35.09% respectively. The most frequent place of death (98% among women intoxicated by alcohol was their own home. The study suggests a close connection between AAI and violence against women. Conclusions The increasing number of cases of death of women suffering from AAI has drawn attention to the serious problem of alcoholism in women in the Slovak Republic during the process of integration into "western" lifestyle and culture.

  8. Developing a social autopsy tool for dengue mortality: a pilot study.

    Directory of Open Access Journals (Sweden)

    María José Arauz

    Full Text Available Dengue fever is a public health problem in the tropical and sub-tropical world. Dengue cases have grown dramatically in recent years as well as dengue mortality. Colombia has experienced periodic dengue outbreaks with numerous dengue related-deaths, where the Santander department has been particularly affected. Although social determinants of health (SDH shape health outcomes, including mortality, it is not yet understood how these affect dengue mortality. The aim of this pilot study was to develop and pre-test a social autopsy (SA tool for dengue mortality.The tool was developed and pre-tested in three steps. First, dengue fatal cases and 'near misses' (those who recovered from dengue complications definitions were elaborated. Second, a conceptual framework on determinants of dengue mortality was developed to guide the construction of the tool. Lastly, the tool was designed and pre-tested among three relatives of fatal cases and six near misses in 2013 in the metropolitan zone of Bucaramanga. The tool turned out to be practical in the context of dengue mortality in Colombia after some modifications. The tool aims to study the social, individual, and health systems determinants of dengue mortality. The tool is focused on studying the socioeconomic position and the intermediary SDH rather than the socioeconomic and political context.The SA tool is based on the scientific literature, a validated conceptual framework, researchers' and health professionals' expertise, and a pilot study. It is the first time that a SA tool has been created for the dengue mortality context. Our work furthers the study on SDH and how these are applied to neglected tropical diseases, like dengue. This tool could be integrated in surveillance systems to provide complementary information on the modifiable and avoidable death-related factors and therefore, be able to formulate interventions for dengue mortality reduction.

  9. Immunohistochemical investigation of hypoxic/ischemic brain damage in forensic autopsy cases.

    Science.gov (United States)

    Kitamura, O

    1994-01-01

    A neuropathological study of 41 forensic autopsy cases of hypoxic/ischemic brain damage has been undertaken, using immunohistochemical staining to detect the 70-kDa heat shock protein (hsp70) and the status of the glial cells. In cases surviving 2-5 h after hypoxic/ischemic injury, ischemic cell changes were seen whereas glial reactions were not apparent. In cases of longer survival, neuronal necrosis and a loss of neurons were seen, and these changes were accompanied by proliferation of glial fibrillary acidic protein (GFAP), vimentin-positive astrocytes and microglia which transformed into rod cells or lipid-laden macrophages. In cases with a history of hypoxic attacks, GFAP-positive and vimentin-negative astrocytes had proliferated in the CA3 and CA4 regions of hippocampus. The cases of severe hypoxic injury, such as an asthmatic attack and choking, showed no ischemic changes in the hippocampal neurons. On the other hand, the CA1 pyramidal cells showed neuronal necrosis in a patient suffering from tetralogy of Fallot (TOF), who survived for 2 h after a traffic accident. Therefore, it is suggested that even moderate hypoxic injury induces astrocytosis in the CA3 and CA4 regions and may affect the neuronal proteins and the metabolism, and that in cases with a history of hypoxic attacks neuronal damage may be severe even several hours after ischemic injury. The protein hsp70 expression was found in the CA2, CA3 and CA4 regions in cases of long-term survival after severe hypoxic/ischemic injury and in cases of alcoholic intake or toluene abuse just before acute death.(ABSTRACT TRUNCATED AT 250 WORDS)

This allowed the phylogenetic placement of the Sverdlovsk strain into a clade with two Asian live vaccine strains, including the Russian Tsiankovskii strain. The genome was examined for evidence of drug resistance manipulation or other genetic engineering, but none was found. The Soviet Sverdlovsk strain genome is consistent with a wild-type strain from Russia that had no evidence of genetic manipulation during its industrial production. This work provides insights into the world’s largest biological weapons program and provides an extensive B. anthracis phylogenetic reference. PMID:27677796

    The occurred death of a convict in prison, police custody cell or in a hospital always attracts public attention and can be considered as a complex phenomenon. The aim of this study is to evaluate the data obtained from autopsies performed to the custody and prison deaths in Istanbul and to discuss the possible solutions by comparing with the literature. It is also aimed to discuss the postponement of the sentence and presidential amnesty facts in Turkey. Deaths of inmates, which occurred in hospitals, prisons, prison medical rooms, police vans and police custody cells between 2010 and 2012 in Istanbul, Turkey were included in the study. Totally 125 cases were found and 98.4% of them were male. Natural deaths accounted for a great majority of deaths (83.2%). The most common natural cause was cardiovascular diseases. Unnatural deaths accounted for 15.2% of the deaths. Death reason cannot be determined for 1.6% of the cases. More than half of the cases (56%) were died at the hospital, 34.4% were died at the prison, 4% of them at the police van, 3.2% were died under police custody and 2.4% were died at the prison medical room. Moreover, twelve of these cases had applied to Third Specialization Board previously for postponement of the sentence or Presidential amnesty. Totally five of these cases found suitable for postponement of the sentence. Prison conditions should be improved, prisoners with chronic diseases should be examined periodically and if appropriate their sentences should be postponed until they heal.

    A deceased 59-year-old woman with insulin dependent diabetes mellitus complicated by chronic thyroiditis and chronic hepatitis was autopsied. She had had diabetes mellitus since she was 30 years old, and insulin therapy was started at 34 years. Laboratory findings were as follows: s-GOT 85, s-GPT 31, gamma-globulin 2.45 g/dl. Immunological tests were positive for anti-smooth muscle antibody and anti-ENA antibody with high titers of antithyroglobulin and anti-microsome antibodies. HLA analysis revealed the presence of DR-4. The thyroid biopsy specimen showed microscopic features characteristic of chronic thyroiditis at 52 years of age. She had been repeatedly admitted for the control of diabetes mellitus. She was admitted for the 9th time in June, 1987 following complaints of abdominal pain. After admission, her general condition became gradually worse, and she died of peritonitis in September, 1987. Pathological examination of the liver revealed an expansion of fibrous tissue on Glisson's capsule accompanied by lymphocytic infiltration and was diagnosed to be chronic inactive hepatitis. As for the thyroid gland, fibrous tissue replaced an extensive area of the thyroid gland, and normal thyroid tissue was not observed. Lymphocytic infiltration was less in comparison with that in the previous biopsy. As for the pancreas, atrophy of exocrine pancreatic tissue and fibrous change in interstitial tissue was observed. Lymphocytic infiltration was also seen in the interstitial exocrine tissue but not in the islet. Immunohistochemical examination of the islets using anti-insulin, glucagon and somatostatin antibodies by ABC peroxidase method showed the selective disappearance of B cells in the islets. The pathological changes in the thyroid gland, liver and pancreas suggest that autoimmune mechanism may be involved in the pathogenesis of chronic thyroiditis, chronic hepatitis and IDDM with exocrine pancreatic impairment in this case.

    Full Text Available Abstract Background In the city of Chennai, India, registration of the fact of death is almost complete but the cause of death is often inadequately recorded on the death certificate. A special verbal autopsy (VA study of 48 000 adult deaths in Chennai during 1995–97 was conducted to arrive at the probable underlying cause of death and to measure cause specific mortality rates for Chennai. Methods Trained non-medical graduates with at least 15 years of formal education interviewed the surviving family members or an associate of the deceased to write a report on the complaints, symptoms, signs, duration and treatment details of illness prior to death. Each report was reviewed centrally by two physicians independently. The reliability was assessed by comparing deaths attributed to cancer by VA with records in Vital Statistics Department and Chennai Cancer Registry. Results The VA reduced the proportion of deaths attributed to unspecified medical causes and unknown causes from 37% to 7% in early adult life and middle age (25–69 yrs and has yielded fewer unspecified causes (only 10% than the death certificate. The sensitivity of VA to identify cancer was 94% in the age group 25–69. Conclusion VA is practicable for deaths in early adult life or middle age and is of more limited value in old age. A systematic program of VA of a representative sample of deaths could assign broad causes not only to deaths in childhood (as has previously been established but also to deaths in early adult life and middle age.

    Mortality statistics by age, sex and cause are the foundation of basic health data required for health status assessment, epidemiological research and formation of health policy. Close to half the deaths in Malaysia occur outside a health facility, are not attended by medical personnel, and are given a lay opinion as to the cause of death, leading to poor quality of data from vital registration. Verbal autopsy (VA) is a very useful tool in diagnosing broad causes of deaths for events that occur outside health facilities. This article reports the development of the VA methods and our principal finding from a validation study. A cross sectional study on nationally representative sample deaths that occurred in Malaysia during 2013 was used. A VA questionnaire suitable for local use was developed. Trained field interviewers visited the family members of the deceased at their homes and conducted face to face interviews with the next of kin. Completed questionnaires were reviewed by trained physicians who assigned multiple and underlying causes. Reference diagnoses for validation were obtained from review of medical records (MR) available for a sample of the overall study deaths. Corresponding MR diagnosis with matched sample of the VA diagnosis were available in 2172 cases for the validation study. Sensitivity scores were good (>75%) for transport accidents and certain cancers. Moderate sensitivity (50% - 75%) was obtained for ischaemic heart disease (64%) and cerebrovascular disease (72%). The validation sample for deaths due to major causes such as ischaemic heart disease, pneumonia, breast cancer and transport accidents show low cause-specific mortality fraction (CSMF) changes. The scores obtained for the top 10 leading site-specific cancers ranged from average to good. We can conclude that VA is suitable for implementation for deaths outside the health facilities in Malaysia. This would reduce ill-defined mortality causes in vital registration data, and yield more

    Suicide is one of the major causes of deaths worldwide. Several studies have showed that alcohol use disorders (AUD) are associated with suicide ideation, suicide attempts, and suicide completion. The majority of the theoretical conceptualization and the bulk of evidence on suicidal behavior and AUD are based on investigations of nonfatal cases because data on nonfatal suicidal behaviors are more readily available. This study aims to explore demographic, clinical, and behavioral dimensions in a large sample of alcohol-related suicides compared to an age-gender matched sample of non-AUD suicides to identify specific factors associated with AUD suicides. We conducted a psychological autopsy study with 158 pairs of AUD and non-AUD suicides. Findings showed that AUD suicides have lower educational level, more biological children and were more likely to be heavy smokers (OR=3.32). Cases were more likely to have family history of alcohol (OR=1.73) and drug abuse (OR=3.61). Subjects had similar prevalences of depressive disorders, anxiety disorders or psychotic disorders. AUD suicides were more likely to meet criteria for current cocaine abuse/dependence (OR=6.64). With respect to personality disorders, AUD suicides presented higher prevalence of Antisocial Personality Disorder (OR=4.68), and were less likely to meet criteria for Avoidant (OR=0.26) and Obsessive-Compulsive Personality Disorders (OR=0.35). Impulsivity scores were higher in AUD suicides (p=0.18), as well as aggression scores (psuicide. After controlling for impulsive-aggressive behaviors, levels of aggression were the only psychopathological feature statistically different between AUD and non-AUD suicides (OR=1.28). In conclusion, higher levels of aggressive behaviors are a specific characteristic of AUD suicides. Apart from substance-related diagnoses, AUD and non-AUD suicides have comparable Axis I psychiatric diagnoses and familial transmission of suicidal behavior. Copyright © 2012 Elsevier Inc. All

  16. What caused the 2012 dengue outbreak in Pucallpa, Peru? A socio-ecological autopsy.

    Dengue is highly endemic in Peru, with increases in transmission particularly since vector re-infestation of the country in the 1980s. Pucallpa, the second largest city in the Peruvian Amazon, experienced a large outbreak in 2012 that caused more than 10,000 cases and 13 deaths. To date, there has been limited research on dengue in the Peruvian Amazon outside of Iquitos, and no published review or critical analysis of the 2012 Pucallpa dengue outbreak. This study describes the incidence, surveillance, and control of dengue in Ucayali to understand the factors that contributed to the 2012 Pucallpa outbreak. We employed a socio-ecological autopsy approach to consider distal and proximal contributing factors, drawing on existing literature and interviews with key personnel involved in dengue control, surveillance and treatment in Ucayali. Spatio-temporal analysis showed that relative risk of dengue was higher in the northern districts of Calleria (RR = 2.18), Manantay (RR = 1.49) and Yarinacocha (RR = 1.25) compared to all other districts between 2004 and 2014. The seasonal occurrence of the 2012 outbreak is consistent with typical seasonal patterns for dengue incidence in the region. Our assessment suggests that the outbreak was proximally triggered by the introduction of a new virus serotype (DENV-2 Asian/America) to the region. Increased travel, rapid urbanization, and inadequate water management facilitated the potential for virus spread and transmission, both within Pucallpa and regionally. These triggers occurred within the context of failures in surveillance and control programming, including underfunded and ad hoc vector control. These findings have implications for future prevention and control of dengue in Ucayali as new diseases such as chikungunya and Zika threaten the region.

    Full Text Available Abstract Background Lymphotoxin-alpha (LTA is a pro-inflammatory cytokine with anti-tumor activity. The objective of this study was to determine whether LTA polymorphisms influence the presence of cancer. Methods LTA polymorphisms C804A (rs1041981, T60N and T495C (rs2229094, C13R were determined in 1,536 consecutive autopsy cases and were registered in the Japanese single-nucleotide polymorphisms (SNPs for geriatric research (JG-SNP Internet database. Tumors were systematically reviewed, pathologically confirmed, and assessed in relation to LTA genotype. Results The study population consisted of 827 males and 709 females, with a mean age of 80 years. Altogether, we studied 606 subjects without cancer and 930 subjects with cancer of the stomach (n = 183, lung (n = 164, colon or rectum (n = 143, or other sites. The presence of cancer was higher in males than in females. The C804A and T495C polymorphisms were associated with cancer in males (CA + AA: CC, adjusted OR = 0.72, 95% CI = 0.53 – 0.99; TC + CC: TT, adjusted OR = 1.45, 95% CI = 1.04 – 2.02; respectively but not in females. In males, the C804A polymorphism was associated with lung cancer (CA + AA: CC, adjusted OR = 0.60, 95% CI = 0.37 – 0.97, whereas the T495C polymorphism was associated with gastric cancer (TC + CC: TT, adjusted OR = 1.68, 95% CI = 1.06 – 2.65. Conclusion We found some evidence of an association between LTA polymorphisms and cancer risk in elderly Japanese men. Further studies in larger populations should examine this hypothesis.

    Full Text Available This work introduces a new way for data visualization. Its name is Digital Application name' Image. Normal digital image is created by digital camera or digital scanner but digital application name image is created by measurements of monitoring data. This work uses the data which is measured by radiation monitoring station and classifies it using fuzzy logic rules to create digital radiation image. The main unique advantage of digital radiation image is that it expresses thousands of measurements in a very clear form through only one picture while the maximum number of measurements does not exceed 100 with other conventional visualization methods. This feature gives a facility to view one year of all recorded measurements in only one photo. This picture helps the user to observe the behavior of thousands of measurements in few minutes instead of spending few hours for reviewing hundreds of charts for the same measurements.

    There is a wide consensus among the feature film production studios that the Internet era brings a new paradigm for film distribution to cinemas worldwide. The benefits of digital cinema to both producers and cinemas are numerous: significantly lower distribution and maintenance costs, immediate access to film libraries, higher presentation quality, and strong potential for developing new business models. Despite these advantages, the studios are still reluctant to jump into the digital age. The main showstopper for digital cinema is the danger of widespread piracy. Piracy already costs Hollywood an estimated two billion dollars annually and digital cinema without proper copyright enforcement could increase this number. In this paper, we present a copyright management system that aims at providing the set of necessary security tools: standard cryptographic primitives and copyright protection mechanisms that enable a reliable and secure feature film delivery system.

    2015-01-01

    Full Text Available Introduction: Neural tube defects (NTD are a group of serious birth defects occurring due to defective closure of neural tube during embryonic development. It comprises of anencephaly, encephalocele and spina bifida. We conducted this prospective fetal autopsy series to study the rate and distribution of NTD, analyze the reproductive factors and risk factors, note any associated anomalies and evaluate the organ weights and their deviation from normal. Materials and Methods: This was a prospective study done over a period of 6 years from August, 2007 to July, 2013. All cases of NTDs delivered as abortion, still born and live born were included. The reproductive and risk factors like age, parity, multiple births, previous miscarriage, obesity, diabetes mellitus, socioeconomic status and use of folic acid during pregnancy were collected.Autopsy was performed according to Virchow′s technique. Detail external and internal examination were carried out to detect any associated anomalies. Gross and microscopic examination of organs were done. Results: Out of 210 cases of fetal and perinatal autopsy done, 72 (34.28% had NTD constituting 49 cases of anencephaly, 16 spina bifida and 7 cases of encephalocele. The mothers in these cases predominantly were within 25-29 years (P = 0.02 and primy (P = 0.01. Female sex was more commonly affected than males (M:F = 25:47, P = 0.0005 There was no history of folate use in majority of cases. Organ weight deviations were >2 standard deviation low in most of the cases. Most common associated anomalies were adrenal hypoplasia and thymic hyperplasia. Conclusion: The authors have made an attempt to study NTD cases in respect to maternal reproductive and risk factors and their association with NTD along with the organ weight deviation and associated anomalies. This so far in our knowledge is an innovative study which was not found in literature even after extensive search.

  6. Pulmonary alveolar microlithiasis with cor pulmonale: an autopsy case demonstrating a marked decrease in pulmonary vascular beds.

    Terada, Tadashi

    2009-11-01

    Pulmonary alveolar microlithiasis (PAM) is a very rare autosomal recessive disorder in which microliths are formed in the alveolar space. PAM is infrequently complicated by pulmonary hypertension, the cause of which is unclear. The author in this paper found that the pulmonary hypertension was caused by a marked decrease in pulmonary vascular beds. Here, an autopsy case of PAM with a marked cor pulmonale is reported. A 14-year-old woman was found to have an abnormal pulmonary shadow, but the cause was unclear. At 24 years, she was diagnosed with a diffuse pulmonary abnormal shadow. At 42 years, she was diagnosed with PAM by imaging techniques. Her condition gradually worsened and she had to be treated with oxygen. She died of respiratory failure at 54 years. An autopsy revealed severe PAM and marked cor pulmonale. The heart weighed 360 g and right ventricular thickness was 10 mm (normal, 2-3 mm). Microscopically, the alveolar space was diffusely filled with microliths, and heart failure cells were recognized. Bone formations were scattered. The alveolar walls showed fibrous thickening, and pulmonary arteries showed atherosclerosis. The right ventricle showed marked cardiac hypertrophy. Chronic severe liver congestion was noted. A morphometric analysis using CD34-stained specimens showed a marked decrease (one tenth) in pulmonary capillary beds (capillary number: 8.6 +/- 3.1 per image), compared with normal lungs obtained from two other autopsies (85.3 +/- 9.4 and 96.2 +/- 10,3). It was concluded that the cor pulmonale and pulmonary hypertension in the present case were caused by the marked decrease of the pulmonary arterial vascular beds. More research is required regarding the etiology and treatment of PAM.

    Fifty patients who died of hepatocellular carcinoma (HCC) were autopsied at the Ciudad Sanitaria "1 degree de Octubre" and the Hospital de la Cruz Roja (Madrid) from 1974 to 1980. Formalin fixed paraffin-embedded autopsy tissue of liver and tumor from the 50 HCC and liver tissue from 50 liver cirrhosis (LC) and from 50 autopsy of non cirrhotic control cases were examined for the presence of cytoplasmic hepatitis B surface antigen (HBsAg). The study was carried out using orcein staining, immunoperoxidase technique (IP) and indirect immunofluorescence (IF). In livers with HCC the HBsAg was detected in the cytoplasm of the hepatocytes in 10 cases (20%) with the orcein staining and in 11 (22%) with the IP and IF techniques. In one case (2%) HBsAg was found in the cytoplasm of tumor cells with the three methods--In four cases (8%) of LC and 2 (4%) control cases cytoplasmic positive cells were found. In 41 patients with HCC HBsAg was studied in the serum by radio-immunoassay (RIA) (13 cases) and immunodiffussion (28 cases). 5 patients (12,1%) were positive and 36 (72%) were negative. In the 5 serum positive HBsAg HCC the staining methods for cytoplasmic HBsAg were positive (100%). In 36 serum negative HBsAg HCC the staining method were positive in 2 cases. The results let us to conclude that HBV is a probable important etiologic factor of HCC in our milieu. 54% of the patients with HCC had a previous history of alcohol abuse; however, histologic features compatible with an alcoholic etiology were found in only 5 cases. Nevertheless we consider that the described histopathologic findings do not exclude excess alcohol consumption as a possible etiologic factor for HCC in our series.

    A 53-year-old woman was admitted to our hospital due to a severe respiratory condition and malnutrition. Radiological and electrophysiological findings suggested the existence of inexplicable cor pulmonale. Although we commenced to determine the causes of her severe condition, she suddenly died 3 days after admission. Postmortem autopsy revealed tumor cell microemboli in the small pulmonary arteries due to gastric cancer. Such a case of cor pulmonale as the first clinical manifestation is exceptionally rare. Occult malignancy should be considered as a differential diagnosis when one encounters a patient with subacutely aggravated respiratory condition and inexplicable cor pulmonale.

    The values of different CC parameters observed were almost similar to the values reported in the other two Indian studies. However, Indian values were found to be more than the Japanese values for length, height and most of the widths of CC. The length and width of CC were found to be less than those of Caucasian population. Generation of this data will help in comparing the CC structure of different sex and ages, to study variations from the normal and may help in surgical planning.

    Highlights: •Infant cases frequently show a diffuse increase in the concentration of lung fields on post-mortem computed tomography (PMCT). •In this study, twenty-two of the thirty sudden infant death cases showed increasing concentration in the entire lung field. •Based on the autopsy results, the lungs simply collapsed and no other abnormal lung findings were identified. •The radiologist should not consider increasing concentration in all lung fields as simply a pulmonary disorder when diagnosing the cause of infant death using PMCT. -- Abstract: Objectives: Infant cases frequently show a diffuse increase in the concentration of lung fields on post-mortem computed tomography (PMCT). However, the lungs often show simply atelectasis at autopsy in the absence of any other abnormal changes. Thus, we retrospectively reviewed the PMCT findings of lungs following sudden infant death and correlated them with the autopsy results. Materials and methods: We retrospectively reviewed infant cases (0 year) who had undergone PMCT and a forensic autopsy at our institution between May 2009 and June 2013. Lung opacities were classified according to their type; consolidation, ground-glass opacity and mixed, as well as distribution; bilateral diffuse and areas of sparing. Statistical analysis was performed to assess the relationships among lung opacities, causes of death and resuscitation attempt. Results: Thirty infant cases were selected, which included 22 sudden and unexplained deaths and 8 other causes of death. Resuscitation was attempted in 22 of 30 cases. Bilateral diffuse opacities were observed in 21 of the 30 cases. Of the 21 cases, 18 were sudden and unexplained deaths. Areas of sparing were observed in 4 sudden and unexplained deaths and 5 other causes of death. Distribution of opacities was not significantly associated with causes of death or resuscitation attempt. The 21 cases with bilateral diffuse opacities included 6 consolidations (4 sudden and unexplained

    Full Text Available Abstract Background Ascertainment of cause for deaths that occur in the absence of medical attention is a significant problem in many countries, including Thailand, where more than 50% of such deaths are registered with ill-defined causes. Routine implementation of standardized, rigorous verbal autopsy methods is a potential solution. This paper reports findings from field research conducted to develop, test, and validate the use of verbal autopsy (VA methods in Thailand. Methods International verbal autopsy methods were first adapted to the Thai context and then implemented to ascertain causes of death for a nationally representative sample of 11,984 deaths that occurred in Thailand in 2005. Causes of death were derived from completed VA questionnaires by physicians trained in ICD-based cause-of-death certification. VA diagnoses were validated in the sample of hospital deaths for which reference diagnoses were available from medical record review. Validated study findings were used to adjust VA-based causes of death derived for deaths in the study sample that had occurred outside hospitals. Results were used to estimate cause-specific mortality patterns for deaths outside hospitals in Thailand in 2005. Results VA-based causes of death were derived for 6,328 out of 7,340 deaths in the study sample that had occurred outside hospitals, constituting the verification arm of the study. The use of VA resulted in large-scale reassignment of deaths from ill-defined categories to specific causes of death. The validation study identified that VA tends to overdiagnose important causes such as diabetes, liver cancer, and tuberculosis, while undercounting deaths from HIV/AIDS, liver diseases, genitourinary (essential renal, and digestive system disorders. Conclusions The use of standard VA methods adapted to Thailand enabled a plausible assessment of cause-specific mortality patterns and a substantial reduction of ill-defined diagnoses.

    Harvey Cushing's monograph The Pituitary Body and Its Disorders describes Case XXXII, a 36-year-old man who presented with gigantism in 1910. The detailed post-mortem exam findings are prefaced with a cryptic statement, describing "inauspicious circumstances" surrounding the autopsy. Although contemporary biographies of Cushing have offered insight into these circumstances, the original surgical file for Case XXXII has not been previously reviewed. The original Johns Hopkins Hospital surgical records were reviewed, and the case of John Turner, who Cushing identified by name in his monograph The Pituitary Body and Its Disorders, was selected for further review. A review of the original surgical file revealed a typewritten note by Dr. Crowe, one of the surgeons who performed the post-mortem exam, with a handwritten addendum by Dr. Cushing. This document provides detail regarding the "inauspicious circumstances" surrounding the autopsy. Namely, the autopsy was conducted without permission of the family, during the funeral service, following a payment to the undertaker. The new information regarding the autopsy of John Turner offers insight into the previously incompletely described circumstances surrounding the autopsy. Additionally, the case illuminates the obligations and ethical quandaries that physician-scientists face.

The autopsies showed massive destruction to the bodies of the two victims but did not identify any signs of acute or chronic medical conditions that could explain loss of control of the airplane. PMCT, histological examination, and forensic chemical analysis also failed to identify an explanation...... of fatal airplane crashes should be subject to forensic autopsy, including PMCT and forensic chemical analysis. The continuous accumulation of knowledge about injury patterns from “simple” accidents is the foundation for the correct analysis of “difficult” accidents....

    Full Text Available Abstract Background The main forms of mercury (Hg exposure in the general population are methylmercury (MeHg from seafood, inorganic mercury (I-Hg from food, and mercury vapor (Hg0 from dental amalgam restorations. While the distribution of MeHg in the body is described by a one compartment model, the distribution of I-Hg after exposure to elemental mercury is more complex, and there is no biomarker for I-Hg in the brain. The aim of this study was to elucidate the relationships between on the one hand MeHg and I-Hg in human brain and other tissues, including blood, and on the other Hg exposure via dental amalgam in a fish-eating population. In addition, the use of blood and toenails as biological indicator media for inorganic and organic mercury (MeHg in the tissues was evaluated. Methods Samples of blood, brain (occipital lobe cortex, pituitary, thyroid, abdominal muscle and toenails were collected at autopsy of 30 deceased individuals, age from 47 to 91 years of age. Concentrations of total-Hg and I-Hg in blood and brain cortex were determined by cold vapor atomic fluorescence spectrometry and total-Hg in other tissues by sector field inductively coupled plasma-mass spectrometry (ICP-SFMS. Results The median concentrations of MeHg (total-Hg minus I-Hg and I-Hg in blood were 2.2 and 1.0 μg/L, and in occipital lobe cortex 4 and 5 μg/kg, respectively. There was a significant correlation between MeHg in blood and occipital cortex. Also, total-Hg in toenails correlated with MeHg in both blood and occipital lobe. I-Hg in both blood and occipital cortex, as well as total-Hg in pituitary and thyroid were strongly associated with the number of dental amalgam surfaces at the time of death. Conclusion In a fish-eating population, intake of MeHg via the diet has a marked impact on the MeHg concentration in the brain, while exposure to dental amalgam restorations increases the I-Hg concentrations in the brain. Discrimination between mercury species is

    Full Text Available Background: Due to a paucity of statistics from vital registration systems in developing countries, the verbal autopsy (VA approach has been used to obtain cause-specific mortality data by interviewing lay respondents on the signs and symptoms experienced by the deceased prior to death. In societies where the culture of mourning is adhered to, the use of VA could clash with traditional norms, thus warranting ethical consideration by researchers. Objective: The study was designed to explore the ethics and cultural context of collecting VA information through a demographic and health surveillance system in the Kassena-Nankana District (KND of Ghana. Study Design: Data were collected through qualitative in-depth interviews (IDIs with four field staff involved in the routine conduct of VAs, four physicians who code VAs, 20 selected respondents to the VA tool, and eight opinion leaders in the KND. The interviews were supplemented with observation by the researchers and with the field notes of field workers. Interviews were audio-recorded, and local language versions transcribed into English. Thematic analysis was performed using QSR NVivo 8 software. Results: The data indicate that cultural sensitivities in VA procedures at both the individual and family levels need greater consideration not only for ethical reasons but also to ensure the quality of the data. Discussions of some deaths are culturally prohibited and therefore lead to refusal of interviews. Families were also concerned about the confidentiality of information because of the potential of blame for the death. VA teams do not necessarily engage in culturally appropriate bereavement practices such as the presentation of tokens. The desire by families for feedback on the cause of death, which is currently not provided by researchers, was frequently expressed. Finally, no standard exists on the culturally acceptable time interval between death and VA interviews. Conclusion: Ethical issues

    Physician assessment historically has been the most common method of analyzing verbal autopsy (VA) data. Recently, the World Health Organization endorsed two automated methods, Tariff 2.0 and InterVA-4, which promise greater objectivity and lower cost. A disadvantage of the Tariff method is that it requires a training data set from a prior validation study, while InterVA relies on clinically specified conditional probabilities. We undertook to validate the hierarchical expert algorithm analysis of VA data, an automated, intuitive, deterministic method that does not require a training data set. Using Population Health Metrics Research Consortium study hospital source data, we compared the primary causes of 1629 neonatal and 1456 1-59 month-old child deaths from VA expert algorithms arranged in a hierarchy to their reference standard causes. The expert algorithms were held constant, while five prior and one new "compromise" neonatal hierarchy, and three former child hierarchies were tested. For each comparison, the reference standard data were resampled 1000 times within the range of cause-specific mortality fractions (CSMF) for one of three approximated community scenarios in the 2013 WHO global causes of death, plus one random mortality cause proportions scenario. We utilized CSMF accuracy to assess overall population-level validity, and the absolute difference between VA and reference standard CSMFs to examine particular causes. Chance-corrected concordance (CCC) and Cohen's kappa were used to evaluate individual-level cause assignment. Overall CSMF accuracy for the best-performing expert algorithm hierarchy was 0.80 (range 0.57-0.96) for neonatal deaths and 0.76 (0.50-0.97) for child deaths. Performance for particular causes of death varied, with fairly flat estimated CSMF over a range of reference values for several causes. Performance at the individual diagnosis level was also less favorable than that for overall CSMF (neonatal: best CCC = 0.23, range 0

    Full Text Available The present study was carried out between 2010 and 2013, a total of 7968 Autopsies were conducted of which 3.31% (n – 264 cases were deaths due to hanging. The most preferred ligature materials were Stole (n – 79 and Bed spread/Sari (n – 68. In 88% of the cases, hanging was complete. Females (n – 136 and males (n – 128 were equally affected. The major age group involved in both the sexes was of 31–40 years, contributing to 50.76% (n – 136 of the self suspension. In 80.58% (n – 213 of the incidents, ligature mark showed discontinuity (incomplete. A Slip type of knot was used in majority of the noose, contributing to 97.73% (n – 258 of the suspensions. In 87.88% (n – 232 of hanging an oblique shaped ligature mark was noticed. The horizontal and near oblique ligature marks were seen only in cases of partial suspension. In 95.45% (n – 252 of the cases, the ligature mark showed blackening of the skin (friction burn. Only 4.54% (n – 12 showed intact skin. The outer layer of the skin over the ligature mark showed displacement in majority of the cases. Married victims contributed to 70.45% of cases. Domestic issues were the commonest reason (n – 82 for self suspension, of which female (n – 68 formed the majority of victims. In 70.83% (n – 187 of cases damage to neck muscle fibers and hemorrhage at the Sternal end of the Sternocleidomastoid muscle were present. In 85.61% (n – 226 of cases the cervical vertebra was intact. In 52.27% (n – 138 of the cases the internal carotid artery showed transverse tear. In 99.42% (n – 248 cases the thyroid cartilage was found intact. The hyoid bone was damaged in 6.06% (n – 16 of the victims. Majority of the victims, 59.09% (n – 156 belonged to low socioeconomic class.
