    Full Text Available Often in tropical practice there is not time or conditions to do a proper autopsy on a patient who has died. A needle biopsy technique is described for limited closed autopsy examination to clariffy organ histology. In this way the clinician may resolve puzzling fatal disease.Muitas vezes, em clínicas de países tropicais, não há tempo nem condições para se realizar uma necropsia adequada em um paciente que foi a óbito. Um técnica de biópsia por punção é descrita para fins de exame em necropsia limitadamente fechada, para esclarecimento da histologia do órgão. Dessa maneira, o clínico pode resolver enigmas de doenças fatais.

  4. Designing verbal autopsy studies

    Directory of Open Access Journals (Sweden)

    Shibuya Kenji


    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.

  6. Congenital hyperthyroidism: autopsy report

    Directory of Open Access Journals (Sweden)

    Lima Marcus Aurelho de


    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.

    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.

    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.

  14. Can postmortem fetal MR imaging replace autopsy?

    Energy Technology Data Exchange (ETDEWEB)

    Cho, Jeong Yeon; Song, Mi Jin [Sungkyunkwan Univ. School of Medicine, Seoul (Korea, Republic of); Kim, Seoung Hyup [Seoul National Univ. College of Medicine, Seoul (Korea, Republic of)


    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.

  15. [Two autopsy cases of primary pituitary carcinoma]. (United States)

    Negishi, K; Suzuki, T; Masuda, Y; Masugi, Y; Teramoto, A; Ohama, E


    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)

  17. Molecular autopsy in victims of inherited arrhythmias. (United States)

    Semsarian, Christopher; Ingles, Jodie


    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.

  18. [Autopsy as a tool for quality assurance: Leipzig]. (United States)

    Gradistanac, T; Wittekind, C


    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.

  19. An Autopsy Checklist: A Monitor of Safety and Risk Management. (United States)

    Shkrum, Michael James; Kent, Jessica


    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.

    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.

  1. [Autopsy case of sarcomatoid malignant pleural mesothelioma]. (United States)

    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.

  2. An autopsy case of traumatic sinus thrombosis. (United States)

    Seto, Y; Takeichi, S


    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.

  3. Autopsy in Islam and current practice in Arab Muslim countries. (United States)

    Mohammed, Madadin; Kharoshah, Magdy A


    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.

  4. Detection of occult disease in tissue donors by routine autopsy. (United States)

    Otero, J; Fresno, M F; Escudero, D; Seco, M; González, M; Peces, R


    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.

  5. Autopsies of the real: Resurrecting the dead

    Full Text Available The sense of the real, or the material—the dead body—as an inextricable part of the sacred does not disappear in the secular environment of the nineteenth and twentieth centuries. This article analyzes specific humanitarian narratives centered on the practice of autopsy and mummification, in which the traces of Catholicism act as a kind of spectral discourse of the imagination, where the real is configured in forms of the uncanny, the monstrous or the sacred.

    El sentido de lo real, de lo material —el cuerpo sin vida— como una inextricable parte de lo sagrado, no desaparece del ambiente secular de los siglos XIX y XX. En los relatos analizados en este artículo se estudia cómo en determinadas narrativas humanitarias centradas en la práctica de la autopsia y la momificación, las huellas del catolicismo actúan como una suerte de discurso espectral de la imaginación, en que lo real se configura en formas de lo siniestro, lo monstruoso o lo sagrado.

    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.

  7. Undetermined Manner of Death: An Autopsy Series. (United States)

    Advenier, Anne-Sophie; Guillard, Nadege; Alvarez, Jean-Claude; Martrille, Laurent; Lorin de la Grandmaison, Geoffroy


    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.

    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 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

  10. Agenesis of the corpus callosum. An autopsy study in fetuses. (United States)

    Kidron, Debora; Shapira, Daniel; Ben Sira, Liat; Malinger, Gustavo; Lev, Dorit; Cioca, Andreea; Sharony, Reuven; Lerman Sagie, Tally


    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.

  11. Neuropathologic findings after organ transplantation. An autopsy study. (United States)

    Schwechheimer, K; Hashemian, A


    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.

    Fakler Johannes K


    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.

  13. Autopsy report of acute necrotizing opticomyelopathy associated with thyroid cancer. (United States)

    Kuroda, Y; Miyahara, M; Sakemi, T; Matsui, M; Ryu, T; Yamaguchi, M; Sasadomi, E; Sugihara, H


    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.

  14. Pierre Robin sequence: case report, the relevance of autopsy

    Directory of Open Access Journals (Sweden)

    Cristiano C. Oliveira


    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.

  15. Extraskeletal Osteosarcoma of the Thigh: An Autopsy Case Report

    Directory of Open Access Journals (Sweden)

    Akihito Nagano


    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.

  16. Postmortem whole-body magnetic resonance imaging as an adjunct to autopsy: preliminary clinical experience. (United States)

    Patriquin, L; Kassarjian, A; Barish, M; Casserley, L; O'Brien, M; Andry, C; Eustace, S


    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.

    Dettmeyer, R; Schmidt, P; Madea, B


    In Germany, autopsies can be ordered by the representatives of the board of health according the Epidemics Law as so called administrative autopsy. If the autopsy is not absolutely necessary, it is mandatory to take into consideration the rights of the deceased persons as well as the rights of the relatives. The decisions of the legislature concerning clinical autopsies must also be considered. The juridical aspects and different types of organising the interrogation of the relatives are explained.

    Abiko, Takashi; Higuchi, Hiroshi; Imada, Ryuichi; Nagai, Kenichi (Iwate Prefectural Central Hospital (Japan))


    A 61-year-old female patient died of a neurological disorder of unknown origin one month after the first visit and was found to have had tuberculous meningitis at autopsy. CT revealed a low density area showing an enlargement of the cerebral ventricle but did not reveal contrast enhancement in the basal cistern peculiar to tuberculous meningitis.

  1. Invasive pulmonary aspergillosis: A study of 39 cases at autopsy

    Directory of Open Access Journals (Sweden)

    Vaideeswar P


    Full Text Available Background: Aspergillus is a common cause of invasive mycosis, especially in immunocompromised or immunosuppressed individuals. 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.

  2. Autopsy findings in patients on postcardiotomy centrifugal ventricular assist. (United States)

    Curtis, J J; Walls, J T; Boley, T M; Schmaltz, R A; Demmy, T L


    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.

    Lumadue, Richard T.


    Institutional autopsies can teach much about why learning centers fail the test of time. St. Augustine Junior College in north Florida, the brainchild of Dr. George Apel, was begun in 1942 and ended seven years later in 1949. The purposes of the short-lived college are identified for discussion in this paper. Also identified are the reasons for…

  4. [Applications and advantages of a multimedia system for autopsies ]. (United States)

    Gualco, M; Benzi, D; Fulcheri, E


    This work evaluates the benefits and applications of computers and multimedia systems in post-mortem examination practice and, more in particular, in the definition of data collection protocols. We examined issues concerning the different aims of autopsy (e.g. diagnostic, scientific, educational, legal), and found that the pathologist's main duty is to acquire a large amount of data in the best possible way. However, despite the will to carry out detailed post-mortem examinations, many pathologic anatomy services face objective difficulties in doing so, especially due to understaffing, lack of time and high costs. The Institute for Pathologic Anatomy of the University of Genoa has developed software for data handling and for outcome reporting, a particularly important aspect in fetal-perinatal diagnosis. The system consists of a relational database in a client-server environment (Fourth Dimension) with two integrated parts. The first part, with unrestricted access, contains patients' personal data, including gender, age, time and date of death, hospital department of origin, person and department requiring the post-mortem examination, hour and time of autopsy, pathologist's name, and clinical diagnosis of death. Using a scanner, a copy of the autopsy application is also field, together with the patient's medical file and any diagnostic images useful to document the case history. The second part of the information system is accessible by pathologists only, and contains the autopsy report. This part is organized to balance two different needs: it allows sufficient space and freedom for autopsy description while providing guidelines for presentation of the report. The structure of the conventional autopsy protocol has been maintained, with subdivisions for all the organs and apparatuses according to topographic criteria. Before this part, a section is dedicated to external cadaver examination and anthropometric data; weight, shape, volume and texture are described for

  5. Heme oxygenase-1 deficiency: the first autopsy case. (United States)

    Kawashima, Atsuhiro; Oda, Yoshio; Yachie, Akihiro; Koizumi, Shoichi; Nakanishi, Isao


    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.

    YAMADA, Kazutaka; Sato, Fumio; HORIUCHI, Noriyuki; HIGUCHI, Tohru; KOBAYASHI, Yoshiyasu; SASAKI, Naoki; NAMBO, Yasuo


    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...

  7. Acute erythroid leukemia: autopsy report of a rare disease

    Directory of Open Access Journals (Sweden)

    Cristiane Rúbia Ferreira


    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.

  8. An unusual autopsy case of cytokine storm-derived influenza-associated encephalopathy without typical histopathological findings: autopsy case report. (United States)

    Nara, Akina; Nagai, Hisashi; Yamaguchi, Rutsuko; Yoshida, Ken-ichi; Iwase, Hirotaro; Mizuguchi, Masashi


    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.

  9. Contrast-enhanced postmortem computed tomography in clinical pathology: enhanced value of 20 clinical autopsies. (United States)

    Westphal, Saskia E; Apitzsch, Jonas C; Penzkofer, Tobias; Kuhl, Christiane K; Mahnken, Andreas H; Knüchel, Ruth


    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.

  10. Study of various congenital anomalies in fetal and neonatal autopsy

    V. Siva Sankara Naik


    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

  11. An exploratory study of the pattern of consent for autopsy in a regional hospital setting.

    LENUS (Irish Health Repository)

    Kaar, T K


    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.

    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.

  16. Dumb bell shaped morphology of liver: an autopsy case report. (United States)

    Jagadish Rao, P P; Murlimanju, B V; Menezes, R G


    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.

  17. Primary diffuse leptomeningeal gliomatosis: An autopsy case report

    Directory of Open Access Journals (Sweden)

    Shaik Afshan Jabeen


    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.

  18. Anatomical Findings in Patients with Infective Endocarditis Diagnosed at Autopsy

    Directory of Open Access Journals (Sweden)

    Miguel Angel Serra Valdés


    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.

  19. Autopsy findings in two siblings with infantile Refsum disease. (United States)

    Chow, C W; Poulos, A; Fellenberg, A J; Christodoulou, J; Danks, D M


    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.

  20. An autopsy case of fatal repellent air freshener poisoning. (United States)

    Hitosugi, Masahito; Tsukada, Chie; Yamauchi, Shinobu; Matsushima, Kazumi; Furukawa, Satoshi; Morita, Satomu; Nagai, Toshiaki


    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.

  1. An Autopsy of Nanofiltration Membrane Used for Landfill Leachate Treatment

    Directory of Open Access Journals (Sweden)

    Ibrahim Demir


    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.

  2. Autopsy practice in forensic pathology - evidence-based or experience-based? a review of autopsies performed on victims of traumatic asphyxia in a mass disaster. (United States)

    Colville-Ebeling, Bonnie; Freeman, Michael; Banner, Jytte; Lynnerup, Niels


    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 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.

    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.

    Pakis, Isil; Polat, Oguz; Yayci, Nesime; Karapirli, Mustafa


    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

  8. Ruptured chordae tendineae in acromegaly. An autopsy case. (United States)

    Kaku, T; Nakashima, Y; Ichiyasu, H; Soejima, M; Baba, K; Kuroiwa, A


    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.

  9. An autopsy case of vagus nerve stimulation following acupuncture. (United States)

    Watanabe, Mayumi; Unuma, Kana; Fujii, Yusuke; Noritake, Kanako; Uemura, Koichi


    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.

  10. An autopsy case of bathtub drowning in epilepsy. (United States)

    Osamura, T; Fushiki, S; Yoshioka, H; Yamanaka, T; Mizuta, R


    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.

  11. An attempt to motivate internal medicine housestaff to obtain consent for autopsies. (United States)

    Sidorov, J


    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 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.

  13. Simplified Symptom Pattern Method for verbal autopsy analysis: multisite validation study using clinical diagnostic gold standards

    Lozano Rafael


    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.

  14. Utility of Postmortem Autopsy via Whole-Body Imaging: Initial Observations Comparing MDCT and 3.0T MRI Findings with Autopsy Findings

    Energy Technology Data Exchange (ETDEWEB)

    Cha, Jang Gyu; Kim, Dong Hun; Paik, Sang Hyun [National Institute of Scientific Investigation, Seoul (Korea, Republic of)


    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

    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...

  18. An autopsy case of methanol induced intracranial hemorrhage. (United States)

    Kim, Hye-Jeong; Na, Joo-Young; Lee, Young-Jik; Park, Jong-Tae; Kim, Hyung-Seok


    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 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.

  20. Voxel-based morphometry in autopsy proven PSP and CBD. (United States)

    Josephs, Keith A; Whitwell, Jennifer L; Dickson, Dennis W; Boeve, Bradley F; Knopman, David S; Petersen, Ronald C; Parisi, Joseph E; Jack, Clifford R


    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.

  1. Algorithms for verbal autopsies: a validation study in Kenyan children. (United States)

    Quigley, M. A.; Armstrong Schellenberg, J. R.; Snow, R. W.


    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

  2. Autopsy findings in 14 patients with penile squamous cell carcinoma. (United States)

    Chaux, Alcides; Reuter, Victor; Lezcano, Cecilia; Velazquez, Elsa; Codas, Ricardo; Cubilla, Antonio L


    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.

    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.

    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.

  6. Fungal infections as a contributing cause of death: An autopsy study

    Directory of Open Access Journals (Sweden)

    Megha S Uppin


    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.

  7. Tales from the grave: Opposing autopsy reports from a body exhumed. (United States)

    Gunasekera, R S; Brown, A B; Costas, E H


    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.

  8. Autopsy rate in suicide is low among elderly in Denmark compared with Finland. (United States)

    Ylijoki-Sørensen, Seija; Boldsen, Jesper Lier; Boel, Lene Warner Thorup; Bøggild, Henrik; Lalu, Kaisa; Sajantila, Antti


    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

  9. Sudden unexpected death in epilepsy: Evaluation of forensic autopsy cases. (United States)

    Zhuo, Luo; Zhang, Yang; Zielke, H Ronald; Levine, Barry; Zhang, Xiang; Chang, Lin; Fowler, David; Li, Ling


    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.

  10. Subclinical elastofibromas in the scapular region in an autopsy series. (United States)

    Järvi, O H; Länsimies, P H


    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.

  11. Coronary atherosclerosis in sudden cardiac death: An autopsy study

    Directory of Open Access Journals (Sweden)

    Sudha M


    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.

  12. Unusual productions of endogenous alcohol: report of two autopsy cases. (United States)

    Moriya, F; Ishizu, H; Miyaishi, S


    We experienced two autopsy cases in which endogenous alcohol productions by saprogens had been unusual. Case 1 is a victim found in a mountain stream 3 to 4 weeks after his death. Since ethanol and n-propanol concentrations in the right intrathoracic bloody fluid, pericardial sac fluid, and blood in the right side of the heart were 0.41 mg/g and 0.052 mg/g, 0.42 mg/g and 0.032 mg/g, and 0.45 mg/g and 0.025 mg/g, respectively. The ethanol detected in those specimens appeared to have been produced postmortem. The femoral muscle and urine, however, contained very little n-propanol though the ethanol levels were 0.21 mg/g and 0.05 mg/g, respectively. Thus, we judged the victim might have died soon after drinking a little alcohol. Case 2 is a victim who was stabbed in the abdomen (liver) with a knife and died due to hemorrhagic shock after 26.5 hours in spite of a peritoneotomy. It was probable that metabolic activities of the liver had decreased significantly after getting a wound. Almost 1 mg/g of ethanol and little n-propanol were detected in the heart blood. In the intraabdominal bloody fluid, however, 2.45 mg/g of ethanol and 0.079 mg/g of n-propanol were detected. n-Propanol level in the bloody fluid is equal to that in severely decomposed body and indicates that a large amount of ethanol was endogenously produced. It may be considered that the unusual ethanol production was caused by the severe peritonitis after the operation.

  13. The value of postmortem computed tomography as an alternative for autopsy in trauma victims: a systematic review

    Energy Technology Data Exchange (ETDEWEB)

    Scholing, M.; Saltzherr, T.P.; Fung Kon Jin, P.H.P.; Ponsen, K.J.; Goslings, J.C. [Academic Medical Center, Trauma Unit, Department of Surgery, Amsterdam (Netherlands); Reitsma, J.B. [Academic Medical Center, Department of Clinical Epidemiology, Biostatistics and Bioinformatics, Amsterdam (Netherlands); Lameris, J.S. [Academic Medical Center, Department of Radiology, Amsterdam (Netherlands)


    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.)

  14. Autopsy in Islam: Considerations for Deceased Muslims and Their Families Currently and in the Future. (United States)

    Sajid, Mohammed Imran


    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.

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

    Directory of Open Access Journals (Sweden)

    Jad Saab


    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.

  16. Diagnostic discrepancies in clinical practice: An autopsy study in patients with heart failure. (United States)

    Issa, Victor Sarli; Dinardi, Layara Fernanda Lipari; Pereira, Thiago Vicente; de Almeida, Lyna Kyria Rodrigues; Barbosa, Thaisa Silveira; Benvenutti, Luiz Alberto; Ayub-Ferreira, Silvia Moreira; Bocchi, Edimar Alcides


    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.

  17. Sudden unexplained death in childhood. An audit of the quality of Autopsy reporting

    LENUS (Irish Health Repository)

    Treacy, A


    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.

  19. Pulmonary mucormycosis with embolism: two autopsied cases of acute myeloid leukemia. (United States)

    Kogure, Yasunori; Nakamura, Fumihiko; Shinozaki-Ushiku, Aya; Watanabe, Akira; Kamei, Katsuhiko; Yoshizato, Tetsuichi; Nannya, Yasuhito; Fukayama, Masashi; Kurokawa, Mineo


    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.

  20. Verbal autopsy of 80,000 adult deaths in Tamilnadu, South India

    Directory of Open Access Journals (Sweden)

    Peto Richard


    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.

  1. [The incidence of urolithiasis (based on autopsy data from the Donetsk Province Clinical Hospital)]. (United States)

    Kurennaia, S S; Uzun, G V; Gerasimenko, A I


    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.

    Ekpo Memfin Dan


    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.

  3. Morphological changes in the digestive system of 93 human immunodeficiency virus positive patients: an autopsy study

    Lucinda Calheiros Guimarães


    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.

    associated with the APOEε4. Instead, autopsy findings of extensive atherosclerosis were associated with possible, not probable or definite AD, and premature death. 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.

  7. Search and removal of radioactive seeds: another application of postmortem computed tomography prior to autopsy. (United States)

    Makino, Yohsuke; Itoda, Nozomi; Ikegaya, Hiroshi; Tanaka, Naoko; Kinoshita, Hiroshi; Motomura, Ayumi; Uno, Takashi; Iwase, Hirotaro


    We herein introduce 3 cases illustrating a new application for pre-autopsy postmortem computed tomography (PMCT). In all 3 cases, there was insufficient background information about the victims provided to the forensic pathologists' department. PMCT showed metallic particles in the prostate gland, an indication of metallic seeds containing radioactive isotopes. In 2 of 3 cases, migrated seeds were also detected by CT imaging in the lungs and the heart. Also in 2 of 3 cases, authorities reinvestigated the victim's history before autopsy was completed, which resulted in following appropriate procedure for dealing with the seeds. Although all 3 cadavers were cremated after autopsy, the International Commission on Radiological Protection (ICRP) discourages cremation for deaths soon after radioactive seeds implantation to prevent air pollution by radioactive isotopes in the ash. Our opinion from the present cases is that pre-autopsy PMCT can be recommended for use by forensic pathologists and guidelines for investigating deaths after permanent brachytherapy should include how to deal with cadavers when medical history is limited.

    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.

  13. Concordance between clinical diagnosis and autopsy findings in two periods in the Hospital Universitario del Valle, Cali

    Directory of Open Access Journals (Sweden)

    Cortés Armando


    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

  14. Post-mortem forensic neuroimaging: correlation of MSCT and MRI findings with autopsy results. (United States)

    Yen, Kathrin; Lövblad, Karl-Olof; Scheurer, Eva; Ozdoba, Christoph; Thali, Michael J; Aghayev, Emin; Jackowski, Christian; Anon, Javier; Frickey, Nathalie; Zwygart, Karin; Weis, Joachim; Dirnhofer, Richard


    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

  15. Classifying perinatal mortality using verbal autopsy: is there a role for nonphysicians?

    Directory of Open Access Journals (Sweden)

    Wallace Dennis


    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.

    Eto, Komyo; Tokunaga, Hidehiro; Nagashima, Kazuo; Takeuchi, Tadao


    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.

  17. The presence of enterovirus, adenovirus, and parvovirus B19 in myocardial tissue samples from autopsies

    PURPOSE: Multiple viruses have been detected in cardiac tissue, but their role in causing myocarditis remains controversial. Viral diagnostics are increasingly used in forensic medicine, but the interpretation of the results can sometimes be challenging. In this study, we examined the prevalence...... of adenovirus, enterovirus, and parvovirus B19 (PVB) in myocardial autopsy samples from myocarditis related deaths and in non-inflamed control hearts in an effort to clarify their significance as the causes of myocarditis in a forensic material. METHODS: We collected all autopsy cases diagnosed with myocarditis...... was made by the serological determination of PVB-specific immunoglobulins M and G. RESULTS: PVB was detected in 33 of 112 (29 %) myocarditis cases and 37 of 84 (44 %) control cases. All of the samples were negative for the presence of adenovirus and enterovirus. Serological evidence of an acute PVB...

  18. Fetal echopsy (ultrasonographic autopsy of an acardius myelancephalus and its correlation with antenatal ultrasonographic findings

    Directory of Open Access Journals (Sweden)

    Balakumar Karippaliyil


    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.

  19. A psychological autopsy study of suicidal hanging from Cuttack, India: focus on stressful life situations. (United States)

    Bastia, Binaya K; Kar, Nilamadhab


    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.

  20. Autopsy reenactment--a useful technique in the evaluation of adhesive tape asphyxia. (United States)

    Herbst, Jonathon; Stanley, Wayne; Byard, Roger W


    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.

  1. CASE REPORT: Papillary Adenoma of Kidney- An Incidental Autopsy Finding: Report of Two Cases

    Directory of Open Access Journals (Sweden)

    Bhakti D. Deshmukh


    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.

  2. Cardiac injuries in car occupants in fatal motor vehicle collisions--an autopsy-based study. (United States)

    Turk, Elisabeth E; Tsang, Yee-Wah; Champaneri, Anisha; Pueschel, Klaus; Byard, Roger W


    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.

  3. Sacrococcygeal chordoma in infancy showing an aggressive clinical course: an autopsy case report. (United States)

    Shinmura, Yuichiro; Miura, Katsutoshi; Yajima, Shuhei; Tsutsui, Yoshihiro


    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.

    Cristiane Rúbia Ferreira


    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.

  5. Dopamine Neurons in the Ventral Tegmental Area: An Autopsy Case of Disorganized Type of Schizophrenia

    Directory of Open Access Journals (Sweden)

    Keiko Ikemoto


    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.

  6. Sepsis and meningoencephalitis due to Rhodotorula glutinis in a patient with systemic lupus erythematosus, diagnosed at autopsy

    Directory of Open Access Journals (Sweden)

    Pamidimukkala Umabala


    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.

  7. Autopsy validation of 123I-FP-CIT dopaminergic neuroimaging for the diagnosis of DLB (United States)

    Attems, Johannes; Colloby, Sean J.; O'Brien, John T.; McKeith, Ian; Walker, Rodney; Lee, Lean; Burn, David; Lett, Debra J.; Walker, Zuzana


    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: 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

  9. Transcriptional profiling of degraded RNA in cryopreserved and fixed tissue samples obtained at autopsy

    Directory of Open Access Journals (Sweden)

    Alhasan Samir


    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.

  10. Association of pulmonary histopathological findings with toxicological findings in forensic autopsies of illicit drug users

    Directory of Open Access Journals (Sweden)

    Todorović Miloš S.


    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

    Ben A Lopman


    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.

  12. Manner of Death Determination in Fire Fatalities: 5-Year Autopsy Data of Istanbul City. (United States)

    Esen Melez, İpek; Arslan, Murat Nihat; Melez, Deniz Oguzhan; Gürler, Ahmet Selçuk; Büyük, Yalçin


    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.

    Multiple endocrine tumors (MET) were observed in 27 of 4,136 autopsy cases (0.3%) of the fixed population including Hiroshima atomic bomb survivors and the control group. The thyroid was the most common organ in which MET occurred, followed by the ovary. Thirteen cases, including two cases of three MET, had MET in both the tyroid and the ovary, 11 of which had been exposed to one rad or more of atomic bomb.

    Balakumar, K; Misha, K


    The prenatal ultrasonographic diagnosis of ectopia cordis associated with a complex intra-cardiac defect (common atrium, common atrioventricular valve with single ventricle) is illustrated in a 32-week gestation fetus. The fetus showed associated features of amniotic band disruption sequence. The cardiac autopsy findings correlated with the antenatal diagnosis. The association of ectopia cordis with amniotic band disruption is rare and infrequently reported in literature.

  17. Single umbilical artery and associated malformations in over 5500 autopsies: relevance for perinatal management. (United States)

    Rittler, Monica; Mazzitelli, Nancy; Fuksman, Rosa; de Rosa, Laura García; Grandi, Carlos


    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.

  18. Modeling and classification of binary data in high dimension : application to verbal autopsy


    Sylla, Seydou Nourou


    The lack of reliable data about the causes of mortality still constitutes an obstacle for the development of poor regions in the world. In these countries, it is not always easy to obtain reliable information about morbidity and mortality. Verbal autopsy has become the main source of information about the causes of death in many places. This method is based on structured questionnaires to determine the symptomsand to get information about the possible cause of death. These data lead to the de...

  19. 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

  20. Hyponatremia at autopsy: an analysis of etiologic mechanisms and their possible significance. (United States)

    Byramji, Angela; Cains, Glenda; Gilbert, John D; Byard, Roger W


    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.

  1. Risk factor analysis for bone marrow histiocytic hyperplasia with hemophagocytosis: an autopsy study. (United States)

    Inai, Kunihiro; Noriki, Sakon; Iwasaki, Hiromichi; Naiki, Hironobu


    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.

    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 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%.

    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 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.

  7. Right atrial mural thrombi: An autopsy study of an under-diagnosed complication at an unusual site

    Directory of Open Access Journals (Sweden)

    P Vaideeswar


    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.

  8. Unusually extensive head trauma in a hydraulic elevator accident: post-mortem MSCT findings, autopsy results and scene reconstruction. (United States)

    Jacobsen, Christina; Schön, Corinna A; Kneubuehl, Beat; Thali, Michael J; Aghayev, Emin


    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.

  9. Drug-related deaths with evidence of intracorporeal drug concealment at autopsy: five case reports. (United States)

    Wilcher, Glenn


    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.

  10. [Psychogical autopsies into suicide among the elderly in Rio de Janeiro]. (United States)

    Minayo, Maria Cecília de Souza; Cavalcante, Fátima Gonçalves; Mangas, Raimunda Matilde do Nascimento; Souza, Juliana Rangel Alves de


    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.

  11. Fatal tolperisone poisoning: autopsy and toxicology findings in three suicide cases. (United States)

    Sporkert, Frank; Brunel, Christophe; Augsburger, Marc P; Mangin, Patrice


    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.

  12. Low-grade Schwann cell neoplasms with leptomeningeal dissemination: clinicopathologic and autopsy findings. (United States)

    Rodriguez, Erika F; Blakeley, Jaishri; Langmead, Shannon; Olivi, Alessandro; Tufaro, Anthony; Tabbarah, Abeer; Berkenblit, Gail; Sacks, Justin M; Newsome, Scott D; Montgomery, Elizabeth; Rodriguez, Fausto J


    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.

  13. Trousseau's Syndrome Caused by Intrahepatic Cholangiocarcinoma: An Autopsy Case Report and Literature Review

    Directory of Open Access Journals (Sweden)

    Takashi Yuri


    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.

  14. FISH analysis of intrapulmonary malignant mesothelioma without a clinically detectable primary pleural lesion: an autopsy case. (United States)

    Hasegawa, Mizue; Sakai, Fumikazu; Sato, Akitoshi; Tsubomizu, Sayuri; Arimura, Ken; Katsura, Hideki; Koh, Eitetsu; Sekine, Yasuo; Wu, Di; Hiroshima, Kenzo


    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.

  15. Pancake kidney with a single ureter: a rare incidental observation at autopsy. (United States)

    Kanchan, Tanuj; Murlimanju, B V; Saralaya, Vasudha V


    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.

  16. Evaluation of point-of-care testing of C-reactive protein in forensic autopsy cases. (United States)

    Soejima, Mikiko; Koda, Yoshiro


    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.

  17. Pathological spectrum of cytomegalovirus infection of renal allograft recipients-an autopsy study from north India. (United States)

    Joshi, Kusum; Nada, Ritambhra; Radotra, Bishan Das; Jha, Vivekanand; Sakhuja, Vinay


    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.

    Yayci, Nesime; Pakis, Isil; Karapirli, Mustafa; Celik, Sefa; Uysal, Cem; Polat, Oguz


    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.

  19. Causes Of Neonatal Mortality : A Community Based Study using Verbal Autopsy Tool

    Directory of Open Access Journals (Sweden)

    Yashpal Jain, Madhav Bansal, Rajesh Tiwari, Pradeep Kumar Kasar


    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.

  20. Small-cell neuroendocrine carcinoma of the esophagus: an autopsy case report

    Directory of Open Access Journals (Sweden)

    Mariana Bellaguarda de Castro Sepulvida


    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.

    Directory of Open Access Journals (Sweden)

    F Panahi


    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.

  2. A Histomorphological Pattern Analysis of Pulmonary Tuberculosis in Lung Autopsy and Surgically Resected Specimens

    Directory of Open Access Journals (Sweden)

    Mamta Gupta


    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.

  3. An autopsy case of preclinical multiple system atrophy (MSA-C). (United States)

    Kon, Tomoya; Mori, Fumiaki; Tanji, Kunikazu; Miki, Yasuo; Wakabayashi, Koichi


    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.

  4. GLUT3 protein and mRNA in autopsy muscle specimens (United States)

    Stuart, C. A.; Wen, G.; Jiang, J.


    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.

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

    Directory of Open Access Journals (Sweden)

    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.

  6. Varied autopsy findings in five treated patients with Gaucher disease and parkinsonism include the absence of Gaucher cells. (United States)

    Monestime, Gianina; Borger, Daniel K; Kim, Jenny; Lopez, Grisel; Allgaeuer, Michael; Jain, Dhanpat; Vortmeyer, Alexander; Wang, Hao-Wei; Sidransky, Ellen


    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.

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

    Directory of Open Access Journals (Sweden)

    Adair Timothy


    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

  10. Post mortem magnetic resonance imaging in the fetus, infant and child: A comparative study with conventional autopsy (MaRIAS Protocol

    Directory of Open Access Journals (Sweden)

    Thayyil Sudhin


    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

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

    LENUS (Irish Health Repository)


    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.

  13. Wilson's disease: A Clinical autopsy case report with review of literature. (United States)

    Raju, Kalyani; Bangalore, Gayathri Nagaraj; Thuruvekere, Suresh Nagaraj; Pathavanalli, Venkatarathnamma Narayanappa


    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.

  14. Autopsy report on pseudo-Bartter syndrome with renal calcification induced by diuretics and diet pills (United States)

    Unuma, Kana; Tojo, Akihiro; Harada, Kazuki; Saka, Kanju; Nakajima, Makoto; Ishii, Takeshi; Fujita, Toshiro; Yoshida, Ken-ichi


    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

  15. Understanding Suicide in Socially Vulnerable Contexts: Psychological Autopsy in a Small Town in Mexico. (United States)

    Chávez-Hernández, Ana-María; Macías-García, Luis-Fernando


    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.

  16. [An autopsy case of sarcomatoid malignant mesothelioma mimicking adenocarcinoma with sarcomatoid elements of lung]. (United States)

    Tamiya, Motohiro; Yamane, Hiroyuki; Terada, Haruko; Matsuno, Osamu; Yamamoto, Suguru


    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).

  17. [Systemic karyomegaly with chronic interstitial nephritis. Discussion of the disease picture based on an autopsy case]. (United States)

    Moch, H; Spöndlin, M; Schmassmann, A; Mihatsch, M J


    Systemic karyomegaly associated with interstitial nephritis was first described in 1978 by Mihatsch. Seven cases have been reported to date. We give an account of an autopsy case of systemic karyomegaly in a 30-year-old Italian man. Bizarre enlargement of nuclei was found in renal tubular epithelial cells, Schwann cells and in smooth muscle cells of vessels and bowel and, less obviously, in endothelial and adventitial cells of vessels, in alveolar epithelial cells and in astrocytes of the brain. These findings were associated with chronic interstitial nephritis, nonspecific hepatopathy, adenocarcinoma of the rectum and multiple sclerosis. The clinical course was marked by chronic renal failure, chronic haemodialysis and renal transplantation. The patient died 8 years after diagnosis in septic-toxic shock. The aetiology and pathogenesis of the disease are discussed.

  18. Advanced chronic lymphoid leukemia with severe bronchopneumonia: an Autopsy Case Report (United States)

    Amaral, Felipe Gomes Campos; Lima, Luiz Guilherme Cernaglia Aureliano; Hatanaka, Veruska Menegatti Anastacio; Siqueira, Sheila Aparecida Coelho


    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

  19. Collecting duct renal cell carcinoma with the syndrome of inappropriate antidiuresis: An autopsy case report

    Directory of Open Access Journals (Sweden)

    Emi Yasuda


    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.

  20. Membranoproliferative glomerulonephritis in a carcinoma with unknown primary: An autopsy study

    Directory of Open Access Journals (Sweden)

    Gupta Kirti


    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.

  1. [The art of improvising. The practice of medico-legal autopsies in the 19th century]. (United States)

    Menenteau, Sandra


    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.

  3. Stainable hepatic iron in 341 African American adults at coroner/medical examiner autopsy

    Directory of Open Access Journals (Sweden)

    Acton Ronald T


    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.

  4. Sudden Cardiac Death in Brazil: A Community-Based Autopsy Series (2006-2010

    Directory of Open Access Journals (Sweden)

    Maria Fernanda Braggion-Santos


    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.

  5. Frequency and nature of testicular and paratesticular lesions in forensic autopsies. (United States)

    de la Grandmaison, Geoffroy Lorin; Marchaut, Jéhanne; Watier, Laurence; Médiouni, Zakia; Charlier, Philippe


    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.

  6. Invasive fungal disease in allogeneic hematopoietic stem cell transplant recipients: an autopsy-driven survey. (United States)

    Sinkó, J; Csomor, J; Nikolova, R; Lueff, S; Kriván, G; Reményi, P; Bátai, A; Masszi, T


    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.

  7. An autopsy case of death due to metabolic acidosis after citric acid ingestion. (United States)

    Ikeda, Tomoya; Usui, Akihito; Matsumura, Takashi; Aramaki, Tomomi; Hosoya, Tadashi; Igari, Yui; Ohuchi, Tsukasa; Hayashizaki, Yoshie; Usui, Kiyotaka; Funayama, Masato


    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.

  8. Trends in autopsy-verified dementia prevalence over 29 years of the Hisayama study. (United States)

    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.

  9. Effects on the estimated cause-specific mortality fraction of providing physician reviewers with different formats of verbal autopsy data

    Directory of Open Access Journals (Sweden)

    Chow Clara


    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

    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

    It is never an easy thing to diagnose heart vascular disease only depending on the unenhanced postmortem computed tomography (PMCT).This article reported a case of sudden natural death after the complaint of anterior chest pain in which coronary artery calcification (CAC) was clearly displayed using PMCT scan.The entire coronary artery system was almost reconstructed via multiplanar reformation (MPR) and volume-rendering reconstruction (VR),and the total calcium score of the coronary arteries was obtained with CaScoring automatic analysis software.The results showed that CAC was conspicuous; the total calcium score was 640.3,considerably higher than 400.The pulmonary ground-glass opacity (GGO) and small amount of fluid both in the subglottic trachea and main bronchi were also found.The imaging results confirmed those of autopsy.In addition,the results concluded that PMCT might serve as an invaluable adjunct to the classic autopsy procedure.

  12. Craniocerebral trauma--congruence between post-mortem computed tomography diagnoses and autopsy results: a 2-year retrospective study. (United States)

    Jacobsen, Christina; Lynnerup, Niels


    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.

    Udnoon, Jitta; Chirachariyavej, Thamrong; Peonim, Vichan


    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.

  14. [On the value of tattoos for identifying unknown bodies - a retrospective study of forensic autopsy cases from Giessen, Germany]. (United States)

    Birngruber, Christoph G; Görner, Nicole; Ramsthaler, H Frank


    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.

  15. One small scan for radiology, one giant leap for forensic medicine - Post-mortem imaging replaces forensic autopsy in a case of traumatic aortic laceration. (United States)

    Ruder, Thomas D; Hatch, Gary M; Thali, Michael J; Fischer, Nadja


    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.

    Mikhaĭlichenko, V A


    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.

  18. 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


    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.

  20. Autopsy Findings of Brainstem in Head Trauma in Comparison with CT Scan Findings in Brain Trauma Ward in Tabriz, Iran

    Directory of Open Access Journals (Sweden)

    Shakeri Bavil Moslem


    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.

  1. A comparative study of cranial, blunt trauma fractures as seen at medicolegal autopsy and by Computed Tomography

    Directory of Open Access Journals (Sweden)

    Lynnerup Niels


    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

    Alka Dattaray Kalgutkar


    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.

  3. Idiopathic mitral valve prolapse with tricuspid, aortic and pulmonary valve involvement: An autopsy case report

    Directory of Open Access Journals (Sweden)

    Heena M Desai


    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.

  4. Understanding the Unique Characteristics of Suicide in China: National Psychological Autopsy Study

    Institute of Scientific and Technical Information of China (English)



    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 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.

    Pallavi Agrawal


    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.

    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.

    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).

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

    Directory of Open Access Journals (Sweden)

    Ariel Barreto Nogueira


    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.

    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.

  11. Ethyl glucuronide and ethyl sulfate in autopsy samples 27 years after death. (United States)

    Politi, Lucia; Morini, Luca; Mari, Francesco; Groppi, Angelo; Bertol, Elisabetta


    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.

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.

  13. Pattern of homicidal deaths autopsied at Penang Hospital, Malaysia, 2007-2009: a preliminary study. (United States)

    Bhupinder, S; Kumara, T K; Syed, A M


    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.

    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.

  15. Coma and death in unrecognized wernicke's encephalopathy an autopsy study: estudo necroscópico

    Directory of Open Access Journals (Sweden)

    Marco Aurélio Lana-peixoto


    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.

  16. The importance of microbiological testing for establishing cause of death in 42 forensic autopsies. (United States)

    Christoffersen, S


    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.

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

    Directory of Open Access Journals (Sweden)

    Aramandla Ramesh


    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.

  18. Autopsy features in a newborn baby affected by a central congenital diaphragmatic hernia. (United States)

    Bolino, Giorgio; Gitto, Lorenzo; Serinelli, Serenella; Maiese, Aniello


    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.

  19. Medical neglect death due to acute lymphoblastic leukaemia: an autopsy case report. (United States)

    Usumoto, Yosuke; Sameshima, Naomi; Tsuji, Akiko; Kudo, Keiko; Nishida, Naoki; Ikeda, Noriaki


    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.

  20. Pathologic findings in the adrenal glands of autopsied patients with acquired immunodeficiency syndrome. (United States)

    Rodrigues, Denise; Reis, Marlene; Teixeira, Vicente; Silva-Vergara, Mário; Filho, Dalmo Correia; Adad, Sheila; Lazo, Javier


    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.

  1. Primary angiitis of CNS : neuropathological study of three autopsied cases with brief review of literature.

    Directory of Open Access Journals (Sweden)

    Panda K


    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.

  2. Pattern of suicide: a review of autopsies conducted at the University Hospital, Kuala Lumpur. (United States)

    Nadesan, K


    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.

  3. Development of novel software to generate anthropometric norms at perinatal autopsy. (United States)

    Cain, Matthew D; Siebert, Joseph R; Iriabho, Egiebade; Gruneberg, Alexander; Almeida, Jonas S; Faye-Petersen, Ona Marie


    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.

  4. Non specific drug distribution in an autopsy case report of fatal caffeine intoxication. (United States)

    Ishikawa, Takaki; Yuasa, Isao; Endoh, Minoru


    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.

  5. Cardiac Tropism of Borrelia burgdorferi: An Autopsy Study of Sudden Cardiac Death Associated with Lyme Carditis. (United States)

    Muehlenbachs, Atis; Bollweg, Brigid C; Schulz, Thadeus J; Forrester, Joseph D; DeLeon Carnes, Marlene; Molins, Claudia; Ray, Gregory S; Cummings, Peter M; Ritter, Jana M; Blau, Dianna M; Andrew, Thomas A; Prial, Margaret; Ng, Dianna L; Prahlow, Joseph A; Sanders, Jeanine H; Shieh, Wun Ju; Paddock, Christopher D; Schriefer, Martin E; Mead, Paul; Zaki, Sherif R


    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.

  6. Pediatric drowning: a 20-year review of autopsied cases: III. Bathtub drownings. (United States)

    Somers, Gino R; Chiasson, David A; Smith, Charles R


    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.

    Pereira, Sanivia Aparecida de Lima; Rodrigues, Denise Bertulucci Rocha; Correia, Dalmo; dos Reis, Marlene Antônia; Teixeira, Vicente de Paula Antunes


    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.

    Kashiwagi, Masayuki; Hara, Kenji; Takamoto, Mutsuo; Kageura, Mitsuyoshi; Matsusue, Aya; Sugimura, Tomoko; Kubo, Shin-ichi


    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.

  9. Can post-mortem computed tomography be considered an alternative for autopsy in deaths due to hemopericardium?

    Lorenzo Gitto; Serenella Serinelli; Francesco P Busard; Valeria Panebianco; Giorgio Bolino; Aniello Maiese


    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.

    Whitby, E.H. E-mail:; Variend, S.; Rutter, S.; Paley, M.N.J.; Wilkinson, I.D.; Davies, N.P.; Sparey, C.; Griffiths, P.D


    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.

  11. The importance of post-mortem computed tomography (PMCT) in confrontation with conventional forensic autopsy of victims of motorcycle accidents. (United States)

    Moskała, Artur; Woźniak, Krzysztof; Kluza, Piotr; Romaszko, Karol; Lopatin, Oleksij


    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.

  12. [Neurocysticercosis: contribution of autopsies in the consolidation of mandatory notification in Ribeiräo Preto-SP,Brazil]. (United States)

    Chimelli, L; Lovalho, A F; Takayanagui, O M


    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.

    Angeles-Angeles, A; Quintanilla Martínez, L; Muñoz Fernández, L; Espinoza Vázquez, B; Victoría Peralta, P


    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.

  15. Alcohol and premature death in Estonian men: a study of forensic autopsies using novel biomarkers and proxy informants

    Directory of Open Access Journals (Sweden)

    Ringmets Inge


    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. The most unique feature of the

    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. Conclusion While delay at home was a main obstacle to prompt and

  17. 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


    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

    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.

    Straka Lubomir


    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.

    Muramatsu Masaaki


    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.

  1. A Bacillus anthracis Genome Sequence from the Sverdlovsk 1979 Autopsy Specimens (United States)

    Sahl, Jason W.; Pearson, Talima; Okinaka, Richard; Schupp, James M.; Gillece, John D.; Heaton, Hannah; Birdsell, Dawn; Hepp, Crystal; Fofanov, Viacheslav; Noseda, Ramón; Fasanella, Antonio; Hoffmaster, Alex; Wagner, David M.


    ABSTRACT 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. PMID:27677796

  3. Immunohistochemical investigation of hypoxic/ischemic brain damage in forensic autopsy cases. (United States)

    Kitamura, O


    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)

  4. 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.

  5. What caused the 2012 dengue outbreak in Pucallpa, Peru? A socio-ecological autopsy. (United States)

    Charette, Margot; Berrang-Ford, Lea; Llanos-Cuentas, Elmer Alejandro; Cárcamo, César; Kulkarni, Manisha


    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.

    Asaranti Kar


    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.

  7. Hepatocellular carcinoma. A study of 50 autopsy cases with detection of hepatitis B surface antigen in fixed tissues. (United States)

    Perez-Barrios, A; Colina-Ruizdelgado, F; Gallego, I; Martinez-Tello, F J


    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.

  8. Pulmonary alveolar microlithiasis with cor pulmonale: an autopsy case demonstrating a marked decrease in pulmonary vascular beds. (United States)

    Terada, Tadashi


    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.

    Jacobsen, Christina; Lynnerup, Niels


    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...

    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......, 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...

  11. Normative Data of Corpus Callosal Morphology in a North-West Indian Population- An autopsy and MRI study

    Directory of Open Access Journals (Sweden)

    Tulika Gupta


    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. Keywords:autopsy brains; corpus callosum; magnetic resonance imaging; morphometric data.

    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

  13. An autopsy case of subacute cor pulmonale due to pulmonary tumor cell emboli in a patient with gastric cancer. (United States)

    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.

  14. Cause-of-death ascertainment for deaths that occur outside hospitals in Thailand: application of verbal autopsy methods

    Directory of Open Access Journals (Sweden)

    Pattaraarchachai Junya


    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.

  15. Mercury in human brain, blood, muscle and toenails in relation to exposure: an autopsy study

    Directory of Open Access Journals (Sweden)

    Morild Inge


    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

  16. Cultural imperatives and the ethics of verbal autopsies in rural Ghana

    Directory of Open Access Journals (Sweden)

    Raymond A. Aborigo


    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

  17. Immunohistochemical diagnosis of myocarditis on (infantile) autopsy material: Does it improve the diagnosis? (United States)

    as valid. At least in infants, the diagnosis of myocarditis from autopsy tissues still requires application of the Dallas criteria. Immunohistochemical methods cannot replace the conventional diagnosis of myocarditis.

  18. The autopsy was conducted "Under most inauspicious circumstances:" John Turner, Harvey Cushing's case XXXII, and his unwitting contributions to the early understanding of acromegaly. (United States)

    Pendleton, Courtney; Wand, Gary; Quinones-Hinojosa, Alfredo


    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.

    An autopsy case of osteosarcoma derived from the right mandible was reported. The case was a 64 year-old-female who received radiotherapy (/sup 60/Co) for Hodgkin's disease in the right neck 15 years prior to the development of her osteosarcoma. By autopsy findings, large nodular growths in the right facial region and the lung metastases of the osteosarcoma were remarkable. No recurrence of Hodgkin's disease was revealed by autopsy. The authors considered that right mandibular osteosarcoma were suspected to be radiation-induced according to the long latent interval and the development of the sarcoma derived from the same location of the irradiation field.

    An 88-year-old male patient with macroglobulinemia was admitted to our hospital because of severe hyponatremia and unconsciousness. Laboratory findings showed decreased inhibition of antidiuretic hormone (ADH) and he was diagnosed with syndrome of inappropriate secretion of ADH (SIADH). Hyponatremia improved with only limitation of water intake and the patient was followed up on a continuing outpatient basis. However, soon after discharge from hospital, his legs started swelling with edema and hyponatremia worsened. He was re-admitted due to a fall at home. Hyponatremia was observed at re-admission. A CRH challenge test showed partial dysfunction of ACTH secretion. Corticosteroid therapy was performed, but the patient subsequently died from pneumonia. Pathological findings at autopsy revealed invasion of plasma cells and amyloid depositions in multiple organs, including the pituitary, adrenal cortex, heart, liver, kidney, lymph nodes and bone marrow. Consistent with these results, fibrosis was observed in the anterior lobe of the pituitary, suggesting that the autopsy findings were related to the clinical observations and diagnosis. This is the first reported case of macroglobulinemia complicated with multiple hormone dysfunction.

  1. The problem with medical research on tissue and organ samples taken in connection with forensic autopsies in France. (United States)

    Rougé-Maillart, C; Dupont, V; Jousset, N


    Currently, in France, it is legally impossible to conduct scientific research on tissue and organ samples taken from forensic autopsies. In fact, the law schedules the destruction of such samples at the end of the judicial investigation, and the common law rules governing cadaver research cannot be applied to the forensic context. However, nothing seems in itself to stand in the way of such research since, despite their specific nature, these samples from forensic autopsies could be subject, following legislative amendments, to common law relating to medical research on samples taken from deceased persons. But an essential legislative amendment, firstly to allow the Biomedicine Agency to become authorized to issue a research permit and secondly, to change the research conditions in terms of the non-opposition of the deceased to said research. Such an amendment would be a true breakthrough because it would allow teams to continue to move forward calmly in research, and allow this research to be placed within a legal framework, which would promote international exchanges.

    Paz, R A; Badra, R E; Martí, H M; Maxit, M J


    A 73 year old retired truck driver and blacksmith was studied in June 1996 for thoracic pain and was diagnosed as acute pericarditis which responded well to steroid treatment. In January 1997, he noted swelling of the abdominal skin, genitalia and limbs, sparing the feet. He was euthyroid, did not have evidence of diabetes or a Raynaud's phenomenon. His proteinogram showed an IgG-Kappa monoclonal paraprotein M component, 1.31 g/oo. TSH and tetraiodotironine were normal; ESR 16 mm in the first hour. As he did not respond to treatment he was referred to our hospital in March 1997. On physical examination the most relevant findings were a non-pitting edema of the abdomen and lower limbs, sparing the feet. An echocardiogram was consistent with an infiltrative cardiomyopathy. Soon after his hospitalization his condition worsened suddenly with severe bradicardia (28/minute) due to a junctional rhythm and righ bundle branch block. He suffered a cardiac arrest and died. The autopsy findings favoured the diagnosis of systemic scleredema adultorum of Buschke. Amyloid deposits were also found although not abundant, with a similar distribution except in the skin. In this article the clinical and autopsy findings are presented in a patient showing coexistence of systemic Buschke's scleredema with an infiltrative cardiomyopathy, IgG Kappa gammopathy and amyloidosis.

    To investigate frequent findings in cases of fatal opioid intoxication in whole-body post-mortem computed tomography (PMCT). PMCT of 55 cases in which heroin and/or methadone had been found responsible for death were retrospectively evaluated (study group), and were compared with PMCT images of an age- and sex-matched control group. Imaging results were compared with conventional autopsy. The most common findings in the study group were: pulmonary oedema (95 %), aspiration (66 %), distended urinary bladder (42 %), cerebral oedema (49 %), pulmonary emphysema (38 %) and fatty liver disease (36 %). These PMCT findings occurred significantly more often in the study group than in the control group (p < 0.05). The combination of lung oedema, brain oedema and distended urinary bladder was seen in 26 % of the cases in the study group but never in the control group (0 %). This triad, as indicator of opioid-related deaths, had a specificity of 100 %, as confirmed by autopsy and toxicological analysis. Frequent findings in cases of fatal opioid intoxication were demonstrated. The triad of brain oedema, lung oedema and a distended urinary bladder on PMCT was highly specific for drug-associated cases of death. (orig.)

    We report an autopsy case of acute pancreatitis with a high serum IgG4 concentration complicated by systemic amyloid A amyloidosis and rheumatoid arthritis (RA). The patient was a 42-year-old Japanese female with a 22-year history of rheumatoid arthritis. She was diagnosed with myasthenia gravis when she was 31-year old. At the onset of pancreatitis, the patient was anti-nuclear antibody-positive,and had high serum gamma globulin and IgG4 levels.Dexamethasone and conventional therapy induced clinical remission and significantly decreased the serum IgG4 and gamma globulin. However, despite the decreased disease parameters, the patient developed a bleeding pseudocyst and died of cardiac failure. In the autopsy examination, it was determined that pancreatitis was probably caused by ischemia due to vascular obstruction caused by amyloid deposition in the pancreas. Even though acute pancreatitis is a rare complication in RA patients, we speculate that an autoimmune pancreatitis-related mechanism and ischemia due to vascular obstruction by amyloid deposition might be attributable to a single source that leads to acute pancreatitis in our particular case.

  5. Analyses of cardiac blood cells and serum proteins with regard to cause of death in forensic autopsy cases. (United States)

    To investigate hematological and serum protein profiles of cadaveric heart blood with regard to the cause of death, serial forensic autopsy cases (n=308, >18 years of age, within 48 h postmortem) were examined. Red blood cells (Rbc), hemoglobin (Hb), platelets (Plt), white blood cells (Wbc), total protein (TP) and albumin (Alb) were examined in bilateral cardiac blood. Blood cell counts, collected after turning the bodies at autopsy, approximated to the clinical values. Postmortem changes were not significant for these markers. In non-head blunt injury cases, Rbc counts, Hb, TP and Alb levels in bilateral cardiac blood were lower in subacute deaths (survival time, 1-12 h) than in acute deaths (survival time blood were significantly higher for non-head injury than for head injury in subacute deaths. In fire fatality cases, Plt count was markedly higher with an automated hematology analyzer than by using a blood smear test, suggesting Rbc fragmentation caused by deep burns, while increases in Wbc count and decreases in Alb levels were seen for subacute deaths. For asphyxiation, Rbc count, Hb, TP and Alb levels in bilateral cardiac blood were higher than other groups, and TP and Alb levels in the right cardiac blood were higher for hanging than for strangulation. These findings suggest that analyses of blood cells and proteins are useful for investigating the cause of death.

  6. Coronary Artery Disease and the Profile of Cardiovascular Risk Factors in South South Nigeria: A Clinical and Autopsy Study

    Directory of Open Access Journals (Sweden)

    Okon Ekwere Essien


    Full Text Available Introduction. Death from coronary artery disease (CAD has been until recently considered rare in Nigeria. We present a report of a study of CAD with its predisposing cardiovascular (CVD risk factors in South South Nigeria. Methods. We examined the autopsy reports of 747 coroner cases and 41 consecutive clinically diagnosed cases of ischemic heart disease seen in South South Nigeria. Results. CAD was diagnosed in 13 (1.6% of 747 autopsies. They were predominantly males, urban residents, and of high social class with combination of CVD risk factors of hypertension, alcohol use, diabetes mellitus, cigarette smoking, poor physical activities, and obesity. The mean serum cholesterol of the clinical subjects was 4.7±1.57 mmol/L and 5.07±1.94 mmol/L for angina and myocardial infarction, respectively, which was higher than the mean total cholesterol for locality of 3.1 mmol/L. Conclusion. CAD and its risk factors are contributing to mortality and morbidity in South South Nigeria. These risk factors include hypertension, alcohol use, diabetes mellitus, cigarette smoking, poor physical activity, and obesity. Nigerians in this locality with CAD have raised serum lipids.

    AIM: To assess the lifetime cumulative incidence of porGl venous thrombosis (PVT) in the general population.METHODS: Between 1970 and 1982, 23 796 autopsies,representing 84% of all in-hospital deaths in the Malmo city population, were performed, using a standardised protocol including examination of the portal vein. PVT patients were characterised and the PVT prevalence at autopsy, an expression of life-time cumulative incidence,assessed in high-risk disease categories and expressed in terms of odds ratios and 95% CI.RESULTS: The population prevalence of PVT was 1.0%.Of the 254 patients with PVT 28% had cirrhosis, 23%primary and 44% secondary hepatobiliary malignancy,10% major abdominal infectious or inflammatory disease and 3% had a myeloproliferative disorder. Patients with both cirrhosis and hepatic carcinoma had the highest PVT risk, OR 17.1 (95% CI 11.1-26.4). In 14% no cause was found; only a minority of them had developed portal-hypertension-related complications.CONCLUSION: In this population-based study, PVT was found to be more common than indicated by previous clinical series. The markedly excess risk in cirrhosis and hepatic carcinoma should warrant an increased awareness in these patients for whom prospective studies of directed intervention might be considered.

    Mukawa, Maki; Nariai, Tadashi; Inaji, Motoki; Tamada, Natsumi; Maehara, Taketoshi; Matsushima, Yoshiharu; Ohno, Kikuo; Negi, Mariko; Kobayashi, Daisuke


    The object of this study was to analyze the pathology of collateral vessels newly induced by indirect bypass surgery for moyamoya disease (MMD). An autopsy analysis was conducted on a 39-year-old woman with MMD who had died of a brainstem infarction. The patient had undergone bilateral indirect bypass surgeries 22 years earlier. Sufficient revascularization via bilateral external carotid arterial systems was confirmed by cerebral angiography before her death. Macroscopic observation of the operative areas revealed countless meandering vessels on the internal surface of the dura mater connected with small vessels on the brain surface and in the subpial brain tissue. Notably, microscopic analysis of these vessels revealed the characteristic 3-layer structure of an arterial wall. This autopsy analysis was the first to confirm that indirect bypass surgery had induced the formation of a new arterial network (arteriogenesis) and that this network had been maintained for more than 20 years to compensate for the chronic cerebral ischemia caused by the MMD.

  9. Evaluation of the World Health Organization 2009 classification of dengue severity in autopsied individuals, during the epidemics of 2011 and 2012 in Brazil

    Directory of Open Access Journals (Sweden)

    Luciano Pamplona de Góes Cavalcanti


    Full Text Available Abstract: INTRODUCTION: The dengue classification proposed by the World Health Organization (WHO in 2009 is considered more sensitive than the classification proposed by the WHO in 1997. However, no study has assessed the ability of the WHO 2009 classification to identify dengue deaths among autopsied individuals suspected of having dengue. In the present study, we evaluated the ability of the WHO 2009 classification to identify dengue deaths among autopsied individuals suspected of having dengue in Northeast Brazil, where the disease is endemic. METHODS: This retrospective study included 121 autopsied individuals suspected of having dengue in Northeast Brazil during the epidemics of 2011 and 2012. All the autopsied individuals included in this study were confirmed to have dengue based on the findings of laboratory examinations. RESULTS: The median age of the autopsied individuals was 34 years (range, 1 month to 93 years, and 54.5% of the individuals were males. According to the WHO 1997 classification, 9.1% (11/121 of the cases were classified as dengue hemorrhagic fever (DHF and 3.3% (4/121 as dengue shock syndrome. The remaining 87.6% (106/121 of the cases were classified as dengue with complications. According to the 2009 classification, 100% (121/121 of the cases were classified as severe dengue. The absence of plasma leakage (58.5% and platelet counts <100,000/mm3 (47.2% were the most frequent reasons for the inability to classify cases as DHF. CONCLUSIONS: The WHO 2009 classification is more sensitive than the WHO 1997 classification for identifying dengue deaths among autopsied individuals suspected of having dengue.

  11. Oxygen as a cause of blindness in premature infants: "autopsy" of a decade of errors in clinical epidemiologic research. (United States)

    Jacobson, R M; Feinstein, A R


    Several intellectual "autopsies" have recently reviewed errors in clinical epidemiologic studies of causation, such as the original claim that amyl nitrite "poppers" caused AIDS. The current autopsy was done to determine why it took more than a decade--1942 to 1954--to end an iatrogenic epidemic in which high-dose oxygen therapy led to retrolental fibroplasia (RLF) in premature infants, blinding about 10,000 of them. The autopsy revealed a museum of diverse intellectual pathology. When first noted, RLF was regarded as neither a new disease nor a postnatal effect. In early investigations, the ophthalmologists did not establish explicit criteria for diagnosis and confused RLF with malformations previously seen in full-term infants. Because the patients were not referred until months after birth, the ophthalmologists assumed that the lesion, which resembled an embryologic structure, must have occurred prenatally. Other events suggesting a prenatal cause for RLF were its strong statistical associations with fetal anomalies, multiple gestations, and maternal infections. Although these events were also associated with prematurity, it was ignored when the RLF cases were compared with controls who were mainly full-term infants. The postnatal timing of RLF was eventually recognized when investigators did cohort studies in premature infants and found that RLF could develop in eyes that were normal at birth. As the search for a cause turned to events occurring after birth, statistical associations were produced for agents such as light, vitamins, iron, vitamin E deficiency, and hypoadrenalism. Each study had its own methodologic flaws: controls were missing for light; co-maneuvers were ignored for vitamins and iron; objective diagnosis was not used for vitamin E deficiency; and the research on hypoadrenalism contained biases in susceptibility and detection as well as problems of a competing outcome event. When the role of oxygen administration was first considered, the

Hospital, Linkoeping (Sweden)); Jackowski, Christian (Inst. of Legal Medicine, Univ. of Zurich, Zurich (Switzerland))


    The importance of autopsy procedures leading to the establishment of the cause of death is well-known. A recent addition to the autopsy work flow is the possibility of conducting postmortem imaging, in its 3D version also called virtual autopsy (VA), using multidetector computed tomography (MDCT) or magnetic resonance imagining (MRI) data from scans of cadavers displayed with direct volume rendering (DVR) 3D techniques. The use of the data and their workflow are presented. Data acquisition was performed and high quality data-sets with submillimeter precision were acquired. New data acquisition techniques such as dual-energy CT (DECT) and quantitative MRI, then were implemented and provided additional information. Particular findings hardly visualized in conventional autopsy can rather easy be seen at the full body CT, such as air distribution, e.g. pneumothorax, pneumopericardium, air embolism, and wound channels. MRI shows natural deaths such as myocardial infarctions. Interactive visualization of these 3D data-sets can provide valuable insight into the corpses and enables non-invasive diagnostic procedures. In postmortem CT imaging, not being limited by a patient depending radiation dose limit the data-sets can, however, be generated with such a high resolution that they become difficult to handle in today's archive retrieval and interactive visualization systems, specifically in the case of full body scans. To take full advantage of these new technologies the postmortem workflow needs to be tailored to the demands and opportunities that the new technologies allow

  13. Organ retention and communication of research use following medico-legal autopsy: a pilot survey of university forensic medicine departments in Japan. (United States)

    Tsujimura-Ito, Takako; Inoue, Yusuke; Yoshida, Ken-ichi


    This study investigated the circumstances and problems that departments of forensic medicine encounter with bereaved families regarding samples obtained from medico-legal autopsies. A questionnaire was posted to all 76 departments of forensic medicine performing medico-legal autopsies in Japan, and responses were received from 48 (63.2%). Of the respondents, 12.8% had approached and communicated with bereaved families about collecting samples from the deceased person during an autopsy and the storage of the samples. In addition, 23.4% of these had informed families that samples might be used in research. Eighteen departments had received enquiries and requests from families about the samples, with most requests concerning their return. The response to such requests varied according to the department. Few departments interacted with the bereaved families regarding the procedure for obtaining autopsy samples, and their methods for handling family concerns differed depending on the person within the department authorised to contact the family. Moreover, the procedures for engaging in such communication have long been unclear, and no legal or ethical consensus or agreement with the general public has been established. It is important for researchers to further discuss the correct way for forensic medicine departments to communicate with bereaved families.

    Kamikura, Isao; Mizutani, Tomohiko; Sakamaki, Shuji; Takasu, Toshiaki; Kawamura, Toshiaki


    A 34-year-old woman presented with urination difficulty and consciousness disturbance, followed by persistent neurologic findings, such as semicomatose mental status and bilateral optic neuritis, and monophasic clinical course. Cranial CT showed multifocal low density areas in cerebral white matter. The patient was clinically diagnosed as having acute disseminated encephalomyelitis. She died of sepsis four months later. Autopsy revealed multifocal large demyelinating lesions confined to the cerebral white matter, shown as low density areas on CT scans, and demyelinating plaques scattered in the optic nerves and chiasm, and cerebral peduncle. The final diagnosis was acute multiple sclerosis. The CT appearance of multifocal low density areas was most likely due to demyelinating lesions causing edema and tissue necrosis. (Namekawa, K.).

    Takahashi, Masatoshi; Katada, Fumiaki; Sato, Susumu; Shibayama, Hidehiro; Fukutake, Toshio; Murayama, Shigeo


    The patient was a 78-year-old man. Three years before admission, he developed transient peripheral neuropathy and purpura, and at admission, he presented with livedo reticularis of both his lower extremities and with mononeuritis multiplex. Vasculitis was not observed, and antiphospholipid antibodies were detected. The nerve and skin biopsies revealed no inflammation; axonal degeneration accompanied by thrombi was found in his arterioles and venules. Based on these findings, he was diagnosed with ischemic peripheral neuropathy due to primary antiphospholipid syndrome. Administration of anticoagulant therapy resulted in an improvement in symptoms; however, two months later, a relapse occurred, and the patient contracted an infection while undergoing immunosuppressive therapy. The infection became fulminant, and the patient succumbed to multiple organ failure. The autopsy revealed a systemic arterial and venous embolism; however, no vasculitis was observed. Antiphospholipid syndrome, which is responsive to antithrombotic treatment, should be considered as a differential diagnosis of mononeuritis multiplex.

  17. Autopsy in older medical patients: concordance in ante- and post-mortem findings and changing trends. (United States)

    Swaro, A; Adhiyaman, V


    Despite modern diagnostics, the discordance between ante- and post-mortem diagnoses is still around 25%, reiterating the need for high post-mortem rates. In our study, 3.5% had class I errors that, had they been detected during life, would or might have affected short-term outcome. Another 14% had major errors, conditions recorded as primary cause of death that were clinically missed or unrecorded but would not have affected the outcome. There has been an unexplained decline in hospital post mortems and more than a third of UK autopsies are now performed under the instruction of the relevant Coroner's office. The UK Coroners' system is currently under judicial and administrative review to improve the speed of and reduce the need for post-mortem analysis.

  18. Midbrain-to-pons ratio in autopsy-confirmed progressive supranuclear palsy: replication in an independent cohort. (United States)

    Kaasinen, Valtteri; Kangassalo, Noora; Gardberg, Maria; Isotalo, Juuso; Karhu, Jari; Parkkola, Riitta; Sonninen, Pirkko


    Recent neuropathologically confirmed clinical data suggest that the midbrain-to-pons ratio, as calculated from conventional brain MRI, has high specificity and sensitivity for the diagnosis of progressive supranuclear palsy (PSP). Here, we aimed to replicate these findings in an independent autopsy-confirmed cohort of 6 PSP patients and 23 non-PSP patients. Patients with confirmed PSP had clearly lower midbrain-to-pons ratios compared to non-PSP patients (p midbrain-to-pons ratios higher than 0.50, whereas all but one PSP patient had a ratio lower than 0.50. The positive predictive value (PPV) of the ratio (midbrain-to-brain ratios constitute reliable and clinically useful estimates of diagnostic midbrain atrophy in relation to PSP pathology.

  19. An autopsy case of hemiconvulsion-hemiplegia-epilepsy syndrome manifesting as cerebral hemiatrophy in an elderly man. (United States)

    Iwase, Tamaki; Yoshida, Mari; Mizuno, Tomoyuki; Sato, Shinya; Nokura, Kazuya


    We report an autopsy case of hemiconvulsion-hemiplegia-epilepsy (HHE) syndrome in a 79-year-old man. HHE syndrome usually occurs in children younger than 4 years of age. Although most HHE syndrome patients live into adult life, only a few cases of the syndrome have been reported in the elderly. In our case, cerebral hemiatrophy, left mesial temporal sclerosis and crossed cerebellar atrophy were observed. Because this is the oldest case ever reported, we further investigated age-related neuropathological changes and found an interhemispheric difference in amyloid-β-related neuropathologic changes. There were almost no senile plaques or amyloid-laden vessels in the left hemisphere. As far as we know, this is the first report of age-related neuropathology in a brain manifesting HHE syndrome.

  20. An Autopsied Case of Malignant Sarcomatoid Pleural Mesothelioma in Which Chest Pain Developed Several Months Earlier without Abnormality on Imaging. (United States)

    Yaguchi, Daizo; Ichikawa, Motoshi; Inoue, Noriko; Kobayashi, Daisuke; Matsuura, Akinobu; Shizu, Masato; Imai, Naoyuki; Watanabe, Kazuko


    The patient experienced chest pain for about 7 months, but a diagnosis could not be made until after death. He was diagnosed with malignant sarcomatoid pleural mesothelioma on autopsy. In this case report, difficult aspects of the diagnosis are discussed. The 70-year-old Japanese man was a driver who transported ceramic-related products. Right chest pain developed in July 2013, but no abnormality was detected on a chest computed tomography (CT) performed in September 2013, and the pain was managed as right intercostal neuralgia. A chest CT performed in late October 2013 revealed a right pleural effusion, and the patient was referred to our hospital in early November 2013. Thoracentesis was performed, but the cytology was negative, and no diagnosis could be made. Close examination was postponed because the patient developed a subarachnoid hemorrhage. He underwent (18)F-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) after discharge from the neurosurgery department, and extensive right pleural thickening and (18)F-FDG accumulation in this region were observed. Based on these findings, malignant pleural mesothelioma was suspected, and a thoracoscopy was performed under local anesthesia in early December 2013, but no definite diagnosis could be made. The patient selected best supportive care and died about 7 months after the initial development of right chest pain. The disease was definitively diagnosed as malignant sarcomatoid pleural mesothelioma by a pathological autopsy. When chronic chest pain of unknown cause is observed and past exposure to asbestos is suspected, actions to prevent delay in diagnosis should be taken, including testing for suspicion of malignant pleural mesothelioma.

    Full Text Available The patient experienced chest pain for about 7 months, but a diagnosis could not be made until after death. He was diagnosed with malignant sarcomatoid pleural mesothelioma on autopsy. In this case report, difficult aspects of the diagnosis are discussed. The 70-year-old Japanese man was a driver who transported ceramic-related products. Right chest pain developed in July 2013, but no abnormality was detected on a chest computed tomography (CT performed in September 2013, and the pain was managed as right intercostal neuralgia. A chest CT performed in late October 2013 revealed a right pleural effusion, and the patient was referred to our hospital in early November 2013. Thoracentesis was performed, but the cytology was negative, and no diagnosis could be made. Close examination was postponed because the patient developed a subarachnoid hemorrhage. He underwent 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET after discharge from the neurosurgery department, and extensive right pleural thickening and 18F-FDG accumulation in this region were observed.

  2. [Implications of nicotine detected in autopsy cases of newborn babies and infants from the perspective of social medicine]. (United States)

    Nishimura, Hiroyuki; Furumiya, Junichi; Nakanishi, Akinori; Hashimoto, Yoshiaki


    Smoking by pregnant and parturient women is generally suspected to increase nicotine levels in fetal and infant blood. Supportive data of nicotine levels in infants is, however, inadequate. We investigated blood and muscle nicotine and cotinine levels in 14 autopsy cases of newborn babies and infants using gas chromatography. Among the 14 cases investigated, nicotine or cotinine was detected in six cases (42.9%). In each of these six cases, the mother was a smoker. Route of exposure to nicotine originating from smoking was transplacental in three cases, via breast milk in one case and secondhand smoke in two cases. Nicotine and cotinine levels in blood from the two cases with placental exposure were 10.6-84.4 ng/ml and 20.3-183 ng/ml, and levels in muscle from one case were 43.9 ng/g and 308 ng/g, respectively. Nicotine and cotinine levels in blood from exposure via breast milk were 19.1 ng/ml and 87.1 ng/ml, and from secondhand smoke were 0 ng/ml and 14.6-20.1 ng/ml. Mean concentrations of blood nicotine and cotinine in 68 autopsy cases of adult habitual smokers were 30.0 ng/ml and 247 ng/ml. Our data for nicotine and cotinine levels in infant blood seem to indicate that some infants who are born and develop under exposure to smoking by family members, particularly the mother, may show high nicotine levels in blood and experience possible health risks.

  3. An independent evaluation of plutonium body burdens in populations near Los Alamos Laboratory using human autopsy data. (United States)

    Gaffney, Shannon H; Donovan, Ellen P; Shonka, Joseph J; Le, Matthew H; Widner, Thomas E


    In the mid-1940s, the United States began producing atomic weapon components at the Los Alamos National Laboratory (LANL). In an attempt to better understand historical exposure to nearby residents, this study evaluates plutonium activity in human tissue relative to residential location and length of time at residence. Data on plutonium activity in the lung, vertebrae, and liver of nearby residents were obtained during autopsies as a part of the Los Alamos Tissue Program. Participant residential histories and the distance from each residence to the primary plutonium processing buildings at LANL were evaluated in the analysis. Summary statistics, including Student t-tests and simple regressions, were calculated. Because the biological half-life of plutonium can vary significantly by organ, data were analyzed separately by tissue type (lung, liver, vertebrae). The ratios of plutonium activity (vertebrae:liver; liver:lung) were also analyzed in order to evaluate the importance of timing of exposure. Tissue data were available for 236 participants who lived in a total of 809 locations, of which 677 were verified postal addresses. Residents of Los Alamos were found to have higher plutonium activities in the lung than non-residents. Further, those who moved to Los Alamos before 1955 had higher lung activities than those who moved there later. These trends were not observed with the liver, vertebrae, or vertebrae:liver and liver:lung ratio data, however, and should be interpreted with caution. Although there are many limitations to this study, including the amount of available data and the analytical methods used to analyze the tissue, the overall results indicate that residence (defined as the year that the individual moved to Los Alamos) may have had a strong correlation to plutonium activity in human tissue. This study is the first to present the results of Los Alamos Autopsy Program in relation to residential status and location in Los Alamos.

  4. Automatic ICD-10 multi-class classification of cause of death from plaintext autopsy reports through expert-driven feature selection (United States)

    Mujtaba, Ghulam; Shuib, Liyana; Raj, Ram Gopal; Rajandram, Retnagowri; Shaikh, Khairunisa; Al-Garadi, Mohammed Ali


    Objectives Widespread implementation of electronic databases has improved the accessibility of plaintext clinical information for supplementary use. Numerous machine learning techniques, such as supervised machine learning approaches or ontology-based approaches, have been employed to obtain useful information from plaintext clinical data. This study proposes an automatic multi-class classification system to predict accident-related causes of death from plaintext autopsy reports through expert-driven feature selection with supervised automatic text classification decision models. Methods Accident-related autopsy reports were obtained from one of the largest hospital in Kuala Lumpur. These reports belong to nine different accident-related causes of death. Master feature vector was prepared by extracting features from the collected autopsy reports by using unigram with lexical categorization. This master feature vector was used to detect cause of death [according to internal classification of disease version 10 (ICD-10) classification system] through five automated feature selection schemes, proposed expert-driven approach, five subset sizes of features, and five machine learning classifiers. Model performance was evaluated using precisionM, recallM, F-measureM, accuracy, and area under ROC curve. Four baselines were used to compare the results with the proposed system. Results Random forest and J48 decision models parameterized using expert-driven feature selection yielded the highest evaluation measure approaching (85% to 90%) for most metrics by using a feature subset size of 30. The proposed system also showed approximately 14% to 16% improvement in the overall accuracy compared with the existing techniques and four baselines. Conclusion The proposed system is feasible and practical to use for automatic classification of ICD-10-related cause of death from autopsy reports. The proposed system assists pathologists to accurately and rapidly determine underlying

  5. Performance of InterVA for assigning causes of death to verbal autopsies: multisite validation study using clinical diagnostic gold standards

    Directory of Open Access Journals (Sweden)

    Flaxman Abraham D


    Full Text Available Abstract Background InterVA is a widely disseminated tool for cause of death attribution using information from verbal autopsies. Several studies have attempted to validate the concordance and accuracy of the tool, but the main limitation of these studies is that they compare cause of death as ascertained through hospital record review or hospital discharge diagnosis with the results of InterVA. This study provides a unique opportunity to assess the performance of InterVA compared to physician-certified verbal autopsies (PCVA and alternative automated methods for analysis. Methods Using clinical diagnostic gold standards to select 12,542 verbal autopsy cases, we assessed the performance of InterVA on both an individual and population level and compared the results to PCVA, conducting analyses separately for adults, children, and neonates. Following the recommendation of Murray et al., we randomly varied the cause composition over 500 test datasets to understand the performance of the tool in different settings. We also contrasted InterVA with an alternative Bayesian method, Simplified Symptom Pattern (SSP, to understand the strengths and weaknesses of the tool. Results Across all age groups, InterVA performs worse than PCVA, both on an individual and population level. On an individual level, InterVA achieved a chance-corrected concordance of 24.2% for adults, 24.9% for children, and 6.3% for neonates (excluding free text, considering one cause selection. On a population level, InterVA achieved a cause-specific mortality fraction accuracy of 0.546 for adults, 0.504 for children, and 0.404 for neonates. The comparison to SSP revealed four specific characteristics that lead to superior performance of SSP. Increases in chance-corrected concordance are attained by developing cause-by-cause models (2%, using all items as opposed to only the ones that mapped to InterVA items (7%, assigning probabilities to clusters of symptoms (6%, and using empirical

  6. Animal-related fatalities--part II: characteristic autopsy findings and variable causes of death associated with envenomation, poisoning, anaphylaxis, asphyxiation, and sepsis. (United States)

    Bury, Danielle; Langlois, Neil; Byard, Roger W


    In addition to blunt and sharp trauma, animal-related fatalities may result from envenomation, poisoning, anaphylaxis, asphyxiation, and sepsis. Although the majority of envenomation deaths are caused by hornets, bees, and wasps, the mechanism of death is most often anaphylaxis. Envenomation resulting from the injection of a poison or toxin into a victim occurs with snakes, spiders, and scorpions on land. Marine animal envenomation may result from stings and bites from jellyfish, octopus, stonefish, cone fish, stingrays, and sea snakes. At autopsy, the findings may be extremely subtle, and so a history of exposure is required. Poisoning may also occur from ingesting certain fish, with three main forms of neurotoxin poisoning involving ciguatera, tetrodotoxin ingestion, and paralytic shellfish poisoning. Asphyxiation may follow upper airway occlusion or neck/chest compression by animals, and sepsis may follow bites. Autopsy analysis of cases requires extensive toxinological, toxicological, and biochemical analyses of body fluids.

  7. An autopsy case of otogenic intracranial abscess and meningitis with Bezold's abscess: evaluation of inflammatory bone destruction by postmortem cone-beam CT. (United States)

    Kanawaku, Yoshimasa; Yanase, Takeshi; Hayashi, Kino; Harada, Kazuki; Kanetake, Jun; Fukunaga, Tatsushige


    The deceased was an unidentified young male found unconscious on a walkway. On autopsy, outer and inner fistulae of the left temporal bone, subcutaneous abscess in the left side of the neck and head, and an intracranial abscess were noted. A portion of the left temporal bone was removed and scanned by cone-beam computed tomography (CT) (normally used for dentistry applications) to evaluate the lesion. The cone-beam CT image revealed roughening of the bone wall and hypolucency of the mastoid air cells, consistent with an inflammatory bone lesion. According to autopsy and imaging findings, the cause of death was diagnosed as intracranial abscess with Bezold's abscess secondary to left mastoiditis as a complication of otitis media. Although determining the histopathology of bone specimens is time-consuming and costly work, we believe that use of cone-beam CT for hard tissue specimens can be useful in forensic practice.

    We report the case of a female who died of suspected acute myocardial infarction. Post-mortem CT angiography (PMCTA) was performed with intravascular contrast infusion before the standard autopsy, and it successfully demonstrated the complete thrombotic occlusion of a coronary artery and also a corresponding perfusion defect on myocardium. We herein describe the PMCTA findings of a cardiac death with special emphasis on the potential benefits of this novel CT technique in forensic practice.

  9. Verbal autopsy interpretation: a comparative analysis of the InterVA model versus physician review in determining causes of death in the Nairobi DSS



    Abstract Background Developing countries generally lack complete vital registration systems that can produce cause of death information for health planning in their populations. As an alternative, verbal autopsy (VA) - the process of interviewing family members or caregivers on the circumstances leading to death - is often used by Demographic Surveillance Systems to generate cause of death data. Physician review (PR) is the most common method of interpreting VA, but this method is a time- and...

  10. The quality and diagnostic value of open narratives in verbal autopsy: a mixed-methods analysis of partnered interviews from Malawi


    King, C; C. Zamawe; Banda, M.; Bar-Zeev, N.; Beard, J.; Bird, J.; Costello, A.; Kazembe, P.; Osrin, D.; Fottrell, E; Vacsurv, C


    Abstract Background Verbal autopsy (VA), the process of interviewing a deceased’s family or caregiver about signs and symptoms leading up to death, employs tools that ask a series of closed questions and can include an open narrative where respondents give an unprompted account of events preceding death. The extent to which an individual interviewer, who generally does not interpret the data, affects the quality of this data, and therefore the assigned cause of death, is poorly documented. We...

    The lack of reliable data about the causes of mortality still constitutes an obstacle for the development of poor regions in the world. In these countries, it is not always easy to obtain reliable information about morbidity and mortality. Verbal autopsy has become the main source of information about the causes of death in many places. This method is based on structured questionnaires to determine the symptomsand to get information about the possible cause of death. These data lead to the de...

  12. An analysis of autopsy cases of non-Hodgkin lymphoma-with special reference to those masquerading as acute febrile illness

    Directory of Open Access Journals (Sweden)

    Sonali Rajesh Saraf


    Conclusion: As NHL present with nonspecific symptoms, these tumours may not be detected in early stages and hence may not be treated appropriately. These patients have weakened immunity and hence are prone to infection and sepsis which can be a major cause of mortality. This autopsy study experience has shown that NHL can masquerade as acute febrile illness which if not detected early and treated adequately can turn fatal.

  13. Monitoring metals in the population living in the vicinity of a hazardous waste incinerator: concentrations in autopsy tissues. (United States)

    Bocio, Ana; Nadal, Martí; Garcia, Francisco; Domingo, Jose L


    This study is a part of a monitoring program for the determination of metals in various human tissues of the population living in the vicinity of a new hazardous waste incinerator (HWI) in Constantí (Tarragona County, Spain). Concentrations of arsenic (As), beryllium (Be), cadmium (Cd), chromium (Cr), mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb), tin (Sn), thallium (Tl), and vanadium (V) were determined in brain, bone, kidney, liver, and lung autopsy samples collected in 2003 from 22 individuals who had been living for at least 10 yr in the area under evaluation. Results were compared with the metal levels obtained in a baseline study, which was performed during the construction of the HWI (1996--1998). In the present survey, As, Be, Tl, and V levels were not detected in any of the analyzed tissues, while Cr concentrations were very close to the limit of detection. The highest levels of Cd and Hg were found in kidney (17.46 microg/g and 0.23 microg/g, respectively), those of Mn in liver (1.07 microg/g), and those of Ni, Pb, and Sn in bone (1.16 microg/g, 2.11 microg/g, and 0.34 microg/g, respectively). In comparison to the results of the baseline study, a general reduction of most metal concentrations was observed in the current survey.

  14. Association between cerebrospinal fluid dopamine concentrations and catechol-O-methyltransferase gene polymorphisms in forensic autopsy cases of methamphetamine abusers. (United States)

    Matsusue, Aya; Ishikawa, Takaki; Michiue, Tomomi; Waters, Brian; Hara, Kenji; Kashiwagi, Masayuki; Takayama, Mio; Ikematsu, Natsuki; Kubo, Shin-Ichi


    Methamphetamine (MA) is an illicit psychostimulant that stimulates the release of catecholamines from sympathetic nerve terminals and is widely abused worldwide. Since catechol-O-methyltransferase (COMT) metabolizes catecholamines and mediates adrenergic, noradrenergic, and dopaminergic signaling responses, we investigated the effects of the COMT polymorphisms rs4633 and rs4680 on cerebrospinal fluid (CSF) catecholamine concentrations in autopsies of subjects who died of drug intoxication. 28 MA abusers and 22 fatal psychotropic drug intoxication cases were evaluated. No correlations were identified between rs4633 or rs4680 polymorphisms and CSF concentrations of adrenaline (Adr), noradrenaline (Nad), or dopamine (DA) in fatal psychotropic cases. However, among MA abusers, DA concentrations in the CSF were significantly higher in those with the T allele (CT and TT) of rs4633 than in CC genotype carriers (p=0.004). Moreover, among MA abusers, DA concentrations were significantly higher in those with the A allele (GA and AA) of rs4680 than in GG genotype carriers (p=0.017). In subsequent haplotype analyses of MA abusers, a strong correlation was identified between two COMT haplotypes and CSF DA concentrations (p=0.002). However, the CSF concentrations of Adr and Nad were not associated with COMT genotypes or haplotypes. The present results indicate that rs4633 and rs4680 polymorphisms influence CSF DA concentrations and MA toxicity in MA abusers.

  15. A retrospective autopsy study of histopathologic spectrum and etiologic trend of fulminant hepatic failure from north India

    Directory of Open Access Journals (Sweden)

    Jain Deepali


    Full Text Available Abstract Background Fulminant hepatic failure (FHF is rapidly fatal and liver transplant is the treatment of choice. The condition is known for its heterogeneity of defining criteria, clinical presentation, histologic spectrum and etiologic factors. The etiology of FHF varies widely, some of which includes viral hepatitis, drug overdose and idiosyncratic drug reactions. The identification of the etiology of FHF is critically important, because it influences the management. A histopathological classification of FHF has not been reported earlier in the literature. Methods The current study was conducted retrospectively on 224 autopsies at a tertiary care hospital in India. In all of these cases the liver was examined grossly and microscopically. Clinical findings, serological data and immunohistochemical findings were correlated with the morphological subtypes and a consensus morphological classification was formulated. Results Young females, especially those in the reproductive age group were most susceptible to the disease. Hepatotropic viruses and drugs were the likely causes in most of the patients. Clinical presentation is important, as delayed onset of encephalopathy or the subacute FHFs lead to maximum mortality. After careful gross and microscopic examination the morphological findings of FHF were divided into four distinct categories. Histologic typing can sometimes be misleading if solely made on H & E slides without application of special stains. Conclusion Fulminant hepatic failure is a medical emergency, proper histological categorization can help in deciding the treatment modalities.

  16. Autopsy case of a giant aneurysm of the anterior communicating artery. Correlation of CT findings and angiographic findings

    Energy Technology Data Exchange (ETDEWEB)

    Shinmura, Fujio; Takayasu, Kenji; Ohiwa, Yasuyuki; Sakata, Ryuichi; Ariwa, Rokuro


    A 64-year-old female was admitted to the hospital with a history of three previous subarachnoid hemorrhages. Neurological examinations revealed incontinentia urinae, gait disturbance, recent memory disturbance and motor weakness on the left side. Plain X-ray films showed a ring-like calcification in the right frontal region. A plain CT scan showed a ring-shaped iso- and high-density area in the intra hemispheric region, the intra bilateral anterior horn of the lateral ventricle, the intra septum pellucidum, and the intra anterior part of the third ventricle. Left carotid angiography showed a large aneurysmal shadow arising from the anterior communicating artery and another from the left middle cerebral artery. In the venous phase the venous angle was supero-posteriorly shifted, and the septal vein was elevated. She died unexpectedly with a status epilepticus of unknown origin. An autopsy specimen revealed that a giant aneurysm occupied the intra ventricular space, the anterior horn of the lateral ventricle, and the right thalamic region. Also, there was a large berry aneurysm arising from the middle cerebral artery. A coronary section through the giant aneurysm showed a markedly compressed left lateral ventricle, right thalamus, and hypothalamus, while the third ventricle had shifted toward the left side.

    A 40-year-old Japanese man visited our hospital after test results indicated elevated hepatobiliary enzymes. He had worked at a printing plant for 8 years and been exposed to organic solvents, including 1,2-dichloropropane (1,2-DCP) and dichloromethane (DCM). Abdominal computed tomography (CT) showed an intrahepatic tumor with dilation of the intrahepatic bile duct. He was diagnosed with intrahepatic cholangiocarcinoma. He had no known risk factors for cholangiocarcinoma. Extended left hepatectomy with lymph node dissection was performed and the tumor was histologically diagnosed as well-differentiated adenocarcinoma. A histological examination also showed biliary intraepithelial preneoplastic lesions in non-cancerous liver areas. Two years after surgery, the patient developed jaundice, esophageal varices and ascites. A CT examination showed liver cirrhosis without recurrence of the cholangiocarcinoma. Although a liver transplantation was planned as a therapeutic option for his liver cirrhosis, his liver failure progressed rapidly and he died before transplantation could be performed. At autopsy, fibrosis was found in the whole liver, especially in the wall of the bile duct and periductal area suggesting chronic bile duct injury due to exposure to organic solvents. Taken together, the current case may suggest that exposure to organic solvents, including 1,2-DCP and DCM, is a risk factor for cholangiocarcinoma. Identifying risk factors for cholangiocarcinoma will help identify the mechanism and help prevent development of the disease.

    Full Text Available Infecção assintomática por Strongyloides stercoralis pode resultar em doença potencialmente fatal em pacientes imunodeprimidos. Os autores relatam caso de hiperinfecção por Strongyloides stercoralis descoberto à autópsia, enfatizando aspectos clinicopatológicos, em homem de 55 anos, em tratamento para mieloma múltiplo. Apresentava, havia um dia, cefaléia intensa, dor abdominal e oligúria desenvolvendo insuficiência respiratória aguda e choque séptico. Devido à dificuldade no diagnóstico, o tratamento empírico antes do início da terapia imunossupressora pode ser a melhor estratégia para prevenir a hiperinfecção pelo verme.Asymptomatic infection due to Strongyloides stercoralis may result in potentially fatal disease in immunodepressed patients. A case of Strongyloides stercoralis hyperinfection discovered at autopsy in a 55-year-old man who had been undergoing treatment for multiple myeloma is reported, emphasizing the clinical and pathological findings. One day earlier, he presented severe headache, abdominal pain and oliguria, from which he developed acute respiratory failure and septic shock. Because of difficulty in reaching this diagnosis, empirical treatment before starting immunosuppressive therapy may be the best strategy for preventing hyperinfection by this worm.

  19. Surface analysis of pilot distribution system pipe autopsies: The relationship of organic and inorganic deposits to input water quality. (United States)

    Fabris, Rolando; Denman, John; Braun, Kalan; Ho, Lionel; Drikas, Mary


    Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) surface analysis was conducted to characterise deposits in polyethylene pipes used in a novel pilot water distribution system (PDS). The system consisted of four (4) parallel distribution systems receiving water from different treatment processes, ranging from conventional coagulation through to an advanced membrane filtration system. After two years of operation, the distribution system was shut down and samples of pipe were collected for autopsy analysis. Inlet and outlet samples from each PDS were collected for purpose of comparison. ToF-SIMS was used to assess chemical differences in surface biofilm accumulation and particulate deposition, which resulted as a consequence of the treatment method and operational mode of each system. These data supplemented previously collected bacteriological and chemical water quality data. Results from the inorganic analysis of the pipes were consistent with corrosion and contamination events that occurred upstream in the corresponding treatment systems. Principal component analysis of data on organic constituents showed oxygen and nitrogen containing fragments were associated with the treatment inlet and outlet samples. These types of signals can often be ascribed to biofilm polysaccharides and proteins. A trend was observed when comparing samples from the same PDS, showing an association of lower molecular weight (MW) organic fragments with the inlet and higher MW organic fragments with the outlet samples.

  20. Autopsy studies of Hashimoto's thyroiditis in Hiroshima and Nagasaki (1954-1974): relation to atomic bomb radiation

    Energy Technology Data Exchange (ETDEWEB)

    Asano, M. (Radiation Effects Research Foundation, Hiroshima, Japan); Norman, J.E. Jr.; Kato, H.; Yagawa, K.


    The authors examined 155 autopsy cases of Hashimoto's thyroiditis in the Life Span Study sample including both A-bomb survivors and controls in Hiroshima and Nagasaki (1954 to 1974). Hashimoto's thyroiditis was classified into lymphoid, diffuse and fibrous types and the following results were obtained. No difference existed in the effects of A-bomb radiation in the incidence and ATB. The ratio of males to females did not reveal statistical significance, even though reversed ratio was noted in the high dose group. The variation of thyroid gland weight in T65 dose or by variant showed no significant pattern, even though the smallest average weight was found in the highest radiation exposure group. The complications in the patients with Hashimoto's thyroiditis were noted to have high prevalance of ovarian cancer and low prevalence of stomach cancer and total cancer. Only two patients with Hashimoto's thyroiditis were found to be complicated with thyroid carcinoma. Among collagen diseases, the prevalence of rheumatic fever and rheumatoid arthritis was high as complication. And the prevalence of combined diseases suggested that no late effect of A-bomb radiation existed.

  1. Evidence for severe atherosclerotic changes in chronic hemodialysis patients: comparative autopsy study against cardiovascular disease patients without chronic kidney disease. (United States)

    Suzuki, Chigure; Nakamura, Satoko; Ishibashi-Ueda, Hatsue; Yoshihara, Fumiki; Kawano, Yuhei


    Atherosclerosis is a major cause of mortality and morbidity among hemodialysis patients, but whether it is more severe in hemodialysis patients than in cardiovascular disease patients without chronic kidney disease is unclear. We examined 46 autopsy patients who had undergone hemodialysis, and age and sex-matched 46 patients with cardiovascular disease and an eGFR of >60 mL/min/1.73 m(2). There was no difference in the prevalence of diabetes or hypertension between the groups. We divided the aorta into four segments: A, ascending artery to arch; B, descending artery to diaphragm; C, suprarenal; and D, infrarenal. We used the classification of the American Heart Association to evaluate atherosclerosis progression. Distribution was scored by the extent to which each segment was damaged: 0, none; 1, less than 1/3; 2, more than 1/3 to less than 2/3; 3, more than 2/3. Histological examination revealed that the progression score (P 60 mL/min/1.73 m(2). Aortic atherosclerosis was aggravated by traditional and chronic kidney disease-related risk factors.

  2. An autopsy case of neuroleptic malignant syndrome (NMS) and its immunohistochemical findings of muscle-associated proteins and mitochondria. (United States)

    Kubo, S; Orihara, Y; Kitamura, O; Ikematsu, K; Tsuda, R; Nakasono, I


    Neuroleptic malignant syndrome (NMS) is a rare but potentially fatal disorder. In forensic cases, post-mortem diagnosis of NMS is sometimes difficult if ante-mortem information, such as neuroleptic ingestion or signs and symptoms, cannot be obtained. A 39-year-old Japanese male on a neuroleptic treatment regimen suddenly became agitated and died. Autopsy revealed muscle rigidity and hyperthermia. Post-mortem examination of blood revealed elevation of creatine phosphokinase-MM (CK-MM) and lactate dehydrogenase-4 and dehydrogenase-5 (LDH-4 and LDH-5). In renal glomeruli and tubules, myoglobin was stained immunohistochemically. From these findings, the cause of death was considered to be NMS. To support the diagnosis of NMS, both skeletal and cardiac muscles were stained with actin, myoglobin, desmin and mitochondria antibodies immunohistochemically. Actin, myoglobin, desmin, and mitochondria had been lost from skeletal, but not from the cardiac muscle, which suggested that only the skeletal muscle was damaged. Moreover, because mitochondria had disappeared only from the skeletal muscle, it was considered that skeletal muscle degeneration was caused by mitochondrial damage. Therefore, it is suggested that immunostaining of skeletal muscle by antibodies for muscle-associated proteins and mitochondria is useful to corroborate a diagnosis of NMS.

  3. Richter’s Type of Incarcerated Obturator Hernia that Presented with a Deep Femoral Abscess: An Autopsy Case Report (United States)

    Yonekura, Satoru; Kodama, Masaaki; Murano, Shunichi; Kishi, Hirohisa; Toyoda, Akihiro


    Patient: Female, 89 Final Diagnosis: Obturator hernia Symptoms: Coxalgia • femoral abscess • gait disorder Medication: — Clinical Procedure: — Specialty: Surgery Objective: Unusual clinical course Background: Richter’s obturator hernia is a rare abdominal hernia that is difficult to diagnose. The purpose of this case report is to show an unusual presentation of a fatal Richter’s obturator hernia that was accompanied by a femoral abscess. Case Report: An 89-year-old woman complained of sudden left coxalgia and a gait disorder but no abdominal symptoms. She had no history of trauma or surgery in the inguinal area. Twenty-three days after her first complaint of coxalgia, the patient was admitted in a coma with necrotizing fasciitis in the left inguinal area. The patient died of asystole due to hyperkalemia. During surveillance for the cause of death, a Richter’s type of incarcerated obturator hernia was identified at autopsy. The incarcerated small intestine had penetrated into the left obturator foramen to form an abscess that extended into the deep femoral region. Conclusions: Obturator hernia accompanied by femoral abscess is extremely rare, but it should be suspected when a patient with no history of trauma or surgery has a femoral abscess, even in the absence of abdominal symptoms.

    Maebashi, Kyoko; Iwadate, Kimiharu; Sakai, Kentaro; Takatsu, Akihiro; Fukui, Kenji; Aoyagi, Miwako; Ochiai, Eriko; Nagai, Tomonori


    Although many cases of fatal hydrogen sulfide poisoning have been reported, in most of these cases, it resulted from the accidental inhalation of hydrogen sulfide gas. In recent years, we experienced 17 autopsy cases of fatal hydrogen sulfide poisoning due to the inhalation of intentionally generated hydrogen sulfide gas. In this study, the concentrations of sulfide and thiosulfate in blood, urine, cerebrospinal fluid and pleural effusion were examined using GC/MS. The sulfide concentrations were blood: 0.11-31.84, urine: 0.01-1.28, cerebrospinal fluid: 0.02-1.59 and pleural effusion: 2.00-8.59 (μg/ml), while the thiosulfate concentrations were blood: 0-0.648, urine: 0-2.669, cerebrospinal fluid: 0.004-0.314 and pleural effusion: 0.019-0.140 (μmol/ml). In previous reports, the blood concentration of thiosulfate was said to be higher than that of sulfide in hydrogen sulfide poisoning cases, although the latter was higher than the former in 8 of the 14 cases examined in this study. These results are believed to be strongly influenced by the atmospheric concentration of hydrogen sulfide the victims were exposed to and the time interval between exposure and death.

    Results of thirty two autopsies in the cases of carcinoma of the cervix experienced in ten years were analyzed. Fourteen cases received surgery and postoperative irradiation. Fourteen cases had external irradiation combined with intracavitary irradiation. Cancer was the cause of death in 81.3% of the whole cases, and it caused cachexia in many cases of the two groups. Uremia and uremic complication were found in 8 cases of the operative group, and in 2 of the radiotherapy group. High incidences of intrapelvic local recurrence and metastasis to other organs were found in the operative group. Cancerous infiltrative involvement of the bladder was often observed, such as in 11 cases of the operated group and in 9 cases of the irradiation group. Cancerous hydronephrosis was found in 10 and 5 cases of the operation and irradiation group, respectively; non-cancerous hydronephrosis was found in 2 of the former and in 4 of the latter. The radiotherapy group had a longer survival period than the other, without severe side effects in the urinary system. This suggested that radiotherapy is of value in treatment of cervical cancer.

  6. Streptococcus agalactiae infective endocarditis complicated by large vegetations at aortic valve cusps along with intracoronary extension: An autopsy case report. (United States)

    Ro, Ayako


    Streptococcus agalactiae infective endocarditis is a rare condition with high mortality owing to complications of large vegetations and systemic emboli. A 49-year-old man was found dead in his house. He had a history of hepatic cirrhosis and had been diagnosed with type 2 diabetes 2years previously. He had presented with a high fever 10days before his death. An autopsy revealed 50mL of purulent pericardial effusion, and S. agalactiae was detected from the culture of this pericardial effusion. Two slender rope-like vegetations were present at the right aortic valve cusp and noncoronary aortic valve cusp. The vegetation at the right aortic valve cusp extended into the right coronary artery. The right coronary artery was broadly occluded by white rod-like material. The mitral valves were also affected, and the posterior papillary muscle was ruptured. Myocardial infarction was not observed. Systemic microscopic Gram-positive bacterial masses were observed in several organs. The death was attributed to acute myocardial ischemia caused by occlusive intracoronary extension of the vegetation at the proximal right coronary artery.

    Tsao, Christin; Thomas, Louise; McGoey, Robin R


    A 73-year-old African-American male was transported to the emergency department due to what emergency personnel described as "coffee ground emesis." He was pronounced dead shortly after arrival. An unlimited autopsy examination was conducted under authorization of the coroner's office. Medical record review revealed that the decedent had been discharged from the hospital just one day prior to his death following a three-day admission for abdominal pain, bloody diarrhea, and a 22-lb unintentional weight loss. Medical history documented hypertension, chronic obstructive lung disease, and a 57-pack-year smoking history. Alcohol abuse was also endorsed, but cessation of use was reported six months prior. During that admit, he was treated for volume-depletion, a urinary tract infection, and suspected infective colitis with antibiotics. Symptoms had resolved on hospital day three, and the patient was discharged home with a two-week course of ciprofloxacin and metronidazole and a follow-up colonoscopy appointment in one month. At the time of autopsy, the decedent was described as cachectic. Figure 1a shows the decedent's esophagus, opened longitudinally. Figure 1b shows the corresponding histology from the esophagus. Other findings documented at autopsy included ischemic bowel disease in the descending colon with patchy superimposed pseudomembranous colitis, emphysematous change, papillary renal cell carcinoma of the right kidney, microscopic prostatic adenocarcinoma, hepatic fibrosis, and intact hepatic hemangiomata.

    Full Text Available Abstract Background and Purpose The impact of traumatic brain injury (TBI on the pathogenesis of Alzheimer disease (AD is still controversial. The aim of our retrospective autopsy study was to assess the impact of TBE and ApoE allele frequency on the development of AD. Material and Methods We examined 1. the incidence of AD pathology (Braak stageing, CERAD, NIA-Reagan Institute criteria in 58 consecutive patients (mean age ± SD 77.0 ± 6.8 years with residual closed TBI lesions, and 2. the frequency of TBI residuals in 57 age-matched autopsy proven AD cases. In both series, ApoE was evaluated from archival paraffin-embedded brain material. Results 1. TBE series: 12.1 % showed definite and 10.3% probable AD (mean age 77.6 and 75.2 years, only 2/13 with ApoEε3/4. From 45 (77.6% non-AD cases (mean age 78.2 years, 3 had ApoEε3/4. The prevalence of 22.4% AD in this small autopsy cohort was significantly higher than 3.3% in a recent large clinical series and 14% in the general population over age 70. 2. In the AD cohort with ApoEε4 allele frequency of 30% similar to other AD series, residuals of closed TBI were seen in 4 brains (7% (mean age ± SD 78.2 ± 6.4, all lacking the ApoEε4 allele. TBI incidence was slightly lower than 8.5% in the clinical MIRAGE study. Conclusions The results of this first retrospective autopsy study of TBI, ApoEε allele frequency, and AD confirm clinical studies suggesting severe TBI to be a risk factor for the development AD higher in subjects lacking ApoEε4 alleles. Further studies in larger autopsy series are needed to elucidate the relationship between TBI, genetic predisposition, and AD.

  9. Patient and surgery related factors associated with fatigue type polyethylene wear on 49 PCA and DURACON retrievals at autopsy and revision

    Directory of Open Access Journals (Sweden)

    Ochsner Peter E


    Full Text Available Abstract Background Polyethylene wear is an important factor for longevity of total knee arthroplasty. Proven and suspicious factors causing wear can be grouped as material, patient and surgery related. There are more studies correlating design and/or biomaterial factors to in vivo wear than those to patient and surgery related factors. Many retrieval studies just include revision implants and therefore may not be representative. This study is aimed to correlate patient- and surgery- related factors to visual wear score by minimizing design influence and include both autopsy and revision implants. Comparison between the groups was expected to unmask patient and surgery-related factors responsible for wear. Methods The amount of joint side wear on polyethylene retrievals was measured using a modification of an established visual wear score. Fatigue type wear was defined as summation of the most severe wear modes of delamination, pitting and cracks. Analysis of patient and surgery related variables suspicious to cause wear included prospectively sampled patient activity which was measured by self reported walking capacity. Statistical analysis was done by univariate analysis of variance. Activity level and implantation time were merged to an index of use and correlated to the wear score. Results Wear score after comparable implantation time was significantly less in the autopsy group. Even so, fatigue type wear accounted for 84 and 93 % of total wear score on autopsy and revision implants respectively. A highly significant influence on wear score was found in time of implantation (p = 0.002, level of activity (p = 0.025 and inserts belonging to revision group (p = 0.006. No influence was found for the kind of patella replacement (p = 0.483. Body mass index and accuracy of component alignment had no significant influence on visual wear score. Fatigue-type wear in the medial compartment was closely correlated to the index of use in the autopsy (R2

  10. Comparing verbal autopsy cause of death findings as determined by physician coding and probabilistic modelling: a public health analysis of 54 000 deaths in Africa and Asia

    Directory of Open Access Journals (Sweden)

    Peter Byass


    Full Text Available Background: Coverage of civil registration and vital statistics varies globally, with most deaths in Africa and Asia remaining either unregistered or registered without cause of death. One important constraint has been a lack of fit–for–purpose tools for registering deaths and assigning causes in situations where no doctor is involved. Verbal autopsy (interviewing care–givers and witnesses to deaths and interpreting their information into causes of death is the only available solution. Automated interpretation of verbal autopsy data into cause of death information is essential for rapid, consistent and affordable processing. Methods: Verbal autopsy archives covering 54182 deaths from five African and Asian countries were sourced on the basis of their geographical, epidemiological and methodological diversity, with existing physician–coded causes of death attributed. These data were unified into the WHO 2012 verbal autopsy standard format, and processed using the InterVA–4 model. Cause–specific mortality fractions from InterVA–4 and physician codes were calculated for each of 60 WHO 2012 cause categories, by age group, sex and source. Results from the two approaches were assessed for concordance and ratios of fractions by cause category. As an alternative metric, the Wilcoxon matched–pairs signed ranks test with two one–sided tests for stochastic equivalence was used. Findings: The overall concordance correlation coefficient between InterVA–4 and physician codes was 0.83 (95% CI 0.75 to 0.91 and this increased to 0.97 (95% CI 0.96 to 0.99 when HIV/AIDS and pulmonary TB deaths were combined into a single category. Over half (53% of the cause category ratios between InterVA–4 and physician codes by source were not significantly different from unity at the 99% level, increasing to 62% by age group. Wilcoxon tests for stochastic equivalence also demonstrated equivalence. Conclusions: These findings show strong concordance

  11. Stenosis of central canal of spinal cord in man: incidence and pathological findings in 232 autopsy cases. (United States)

    Milhorat, T H; Kotzen, R M; Anzil, A P


    The central canal of the spinal cord is generally regarded as a vestigial structure that is obliterated after birth in 70% to 80% of the general population. This report describes the first detailed histological study of the human central canal in 232 subjects ranging in age from 6 weeks' gestation to 92 years. Whole spinal cords were harvested at autopsy and sectioned serially from the conus medullaris to the upper medulla. Histological findings and morphometric analysis of the cross-sectional luminal area were used to grade stenosis at seven levels of the canal. Varying grades of stenosis were present at one or more levels in none (0%) of 60 fetuses, one (3%) of 34 infants, three (18%) of 17 children, 21 (88%) of 24 adolescents and young adults, 67 (96%) of 70 middle-aged adults, and all 27 adults aged 65 years or older (100%). The stenotic process was most pronounced in the thoracic segments of the canal and involved more levels with higher grades of stenosis in older individuals. Histological findings consisted of disorganization of the ependymal epithelium, formation of ependymal rosettes or microcanals, proliferation of subependymal gliovascular buds, and intracanalicular gliosis. These features are consistent with a pathological lesion involving ependymal injury and scarring and are less compatible with an involutional or degenerative process. Stenosis of the central canal probably influences the anatomical features of syringomyelia and may account for variations in cavity formation such as the prevalence of holocord syrinxes in children, the formation of focal and paracentral syrinxes in adults, and the rare incidence of syrinx formation in many older individuals with acquired lesions known to produce syringomyelia.

  12. Reliability of reporting of HIV status and antiretroviral therapy usage during verbal autopsies: a large prospective study in rural Malawi

    Directory of Open Access Journals (Sweden)

    Estelle M. Mclean


    Full Text Available Objective: Verbal autopsies (VAs are interviews with a relative or friend of the deceased; VAs are a technique used in surveillance sites in many countries with incomplete death certification. The goal of this study was to assess the accuracy and validity of data on HIV status and antiretroviral therapy (ART usage reported in VAs and their influence on physician attribution of cause of death. Design: This was a prospective cohort study. Methods: The Karonga Health and Demographic Surveillance Site monitors demographic events in a population in a rural area of northern Malawi; a VA is attempted on all deaths reported. VAs are reviewed by clinicians, who, with additional HIV test information collected pre-mortem, assign a cause of death. We linked HIV/ART information reported by respondents during adult VAs to database information on HIV testing and ART use and analysed agreement using chi-square and kappa statistics. We used multivariable logistic regression to analyse factors associated with agreement. Results: From 2003 to 2014, out of a total of 1,952 VAs, 80% of respondents reported the HIV status of the deceased. In 2013–2014, this figure was 99%. Of those with an HIV status known to the study, there was 89% agreement on HIV status between the VA and pre-mortem data, higher for HIV-negative people (92% than HIV-positive people (83%. There was 84% agreement on whether the deceased had started ART, and 72% of ART initiation dates matched within 1 year. Conclusions: In this population, HIV/ART information was often disclosed during a VA and matched well with other data sources. Reported HIV/ART status appears to be a reliable source of information to help classification of cause of death.

    Full Text Available Background: Human immunodeficiency virus (HIV infection in India has now been prevalent over three decades, and an increasing number of children are being affected with HIV. The spectrum of pathologic lesions in children with acquired immunodeficiency syndrome (AIDS in India has not been well described. Materials and Methods: A review of systematically conducted autopsies of 11 (10 boys and 1 girl children with AIDS is presented. Results: The mode of HIV transmission in 6 children was vertical; in one it was blood transfusion and in 4 children route was presumably vertical as these were children of orphanage. The clinical manifestations were failure to thrive; 9 children, persistent gastroenteritis; 8, recurrent fever; 5, bacterial infections; 5, hepatosplenomegaly; 5, candidiasis; 1, scabies; 1, skin rash; 2, tuberculous (TB meningitis; 1 and paraplegia; in 1 child. The spectrum of pathologic lesions observed were precocious involution in thymus in 3 and dysinvolution in 2 cases. Infectious diseases comprised of TB; 4 cases, cytomegalovirus infection (CMV 4; bacterial pneumonia and meningitis; 7, and esophageal candidiasis in 2 cases. Dual or multiple infections were observed in 9 (82% cases; these comprised of two lesions in 2, three lesions in 2, four lesions in 4, and five lesions in 1 case. TB, bacterial pneumonia, meningitis, and CMV infection are the most frequent causes of death in children with AIDS. Vascular lesions showing features of arteriopathy were observed in 5 cases and brain in one case showed non-Hodgkin's lymphoma. Conclusions: This study provides a better insight into the spectrum of pathologic lesions in children with AIDS in India. TB and CMV infection has been found to be the most prevalent infection in our children.

  14. EtG and EtS in Autopsy Blood Samples With and Without Putrefaction Using UPLC-MS-MS. (United States)

    Hegstad, Solfrid; Kristoffersen, Lena; Liane, Veronica H; Spigset, Olav


    Analytical challenges related to postmortem specimens are well known. The degree of putrefaction of the corpse will influence the quality of the blood samples, and both the efficiency of sample preparation and the subsequent chromatographic performance can be affected. An ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS-MS) method was developed and validated for the determination of ethyl glucuronide (EtG) and ethyl sulfate (EtS) in postmortem whole blood. Sample preparation prior to UPLC-MS-MS analysis consisted of protein precipitation and filtration through a phospholipid removal plate. Chromatography was achieved using an HSS T3 column and gradient elution with formic acid in water in combination with methanol. The injection volume was 0.5 µL. Negative electrospray ionization was performed in the multiple reaction monitoring mode. Two transitions were monitored for the analytes and one for the internal standards. The between-assay relative standard deviations were in the range of 1.7-7.0% and the limits of quantification were 0.025 and 0.009 mg/L for EtG and EtS, respectively. Recovery was 51-55% and matrix effects ranged from 98% to 106% (corrected with internal standard). Blood samples from nine autopsy cases with various extents of putrefaction were analyzed. The sample preparation efficiently removed the phospholipids from the blood specimens. The samples were clean and the analytical quality of the chromatographic performance was satisfactory for both analytes irrespective of the degree of putrefaction.

  15. Revealing the burden of maternal mortality: a probabilistic model for determining pregnancy-related causes of death from verbal autopsies

    Directory of Open Access Journals (Sweden)

    Desta Teklay


    Full Text Available Abstract Background Substantial reductions in maternal mortality are called for in Millennium Development Goal 5 (MDG-5, thus assuming that maternal mortality is measurable. A key difficulty is attributing causes of death for the many women who die unaided in developing countries. Verbal autopsy (VA can elicit circumstances of death, but data need to be interpreted reliably and consistently to serve as global indicators. Recent developments in probabilistic modelling of VA interpretation are adapted and assessed here for the specific circumstances of pregnancy-related death. Methods A preliminary version of the InterVA-M probabilistic VA interpretation model was developed and refined with adult female VA data from several sources, and then assessed against 258 additional VA interviews from Burkina Faso. Likely causes of death produced by the model were compared with causes previously determined by local physicians. Distinction was made between free-text and closed-question data in the VA interviews, to assess the added value of free-text material on the model's output. Results Following rationalisation between the model and physician interpretations, cause-specific mortality fractions were broadly similar. Case-by-case agreement between the model and any of the reviewing physicians reached approximately 60%, rising to approximately 80% when cases with a discrepancy were reviewed by an additional physician. Cardiovascular disease and malaria showed the largest differences between the methods, and the attribution of infections related to pregnancy also varied. The model estimated 30% of deaths to be pregnancy-related, of which half were due to direct causes. Data derived from free-text made no appreciable difference. Conclusion InterVA-M represents a potentially valuable new tool for measuring maternal mortality in an efficient, consistent and standardised way. Further development, refinement and validation are planned. It could become a routine

    Waliszewski, Stefan M; Carvajal, Octavio; Infanzón, Rosa M; Gómez-Arroyo, Sandra; Villalobos-Pietrini, Rafael; Trujillo, Patricia; Hart, Mary Maxwell


    Samples of human blood sera (N = 118) for the determination of organochlorine pesticide levels were obtained at autopsy from auto accident victims in Veracruz, Mexico, during the years 2000 and 2001. The presence of hexachlorobenzene (HCH), beta-hexachlorocyclohexane (beta-HCH), 2,2-bis(p-chlorophenyl)-1,1-dichloroethylene (p,p'-DDE), 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (p,p'-DDT), and o,p'-DDT was confirmed by gas-liquid-electron-capture detection chromatography. During the years 2000 and 2001, the respective mean levels of (a) HCB, (b) beta-HCH, (c) p,p'-DDE, (d) o,p'-DDT, (e) p,p'-DDT, and (f) total DDT were (a) 2.1 ng/ml and 1.4 ng/ml, (b) 3.0 ng/ml and 3.6 ng/ml, (c) 21.1 ng/ml and 23.8 ng/ml, (d) 1.2 ng/ml and 0.8 ng/ml, (e) 3.3 ng/ml and 2.5 ng/ml, and, finally, (f) 25.4 ng/ml and 27.1 ng/ml, respectively. High levels of persistent organochlorine pesticides were--and continue to be--present in the blood of individuals who live in Mexico. Levels of insecticide metabolites (e.g., beta-HCH, p,p'-DDE) in blood have increased during recent years (1997-2001), but levels of p,p'-DDT decreased in 2001 because the use of DDT for the control of malaria in Mexico was restricted.

    Hussain-Alkhateeb, Laith; Fottrell, Edward; Petzold, Max; Kahn, Kathleen; Byass, Peter


    Background Understanding how lay people perceive the causes of mortality and their associated risk factors is important for public health. In resource-limited settings, where verbal autopsy (VA) is used as the most expedient method of determining cause of death, it is important to understand how pre-existing concepts of cause of death among VA-informants may influence their VA-responses and the consequential impact on cause of death assessment. This study describes the agreement between VA-derived causes of death and informant-perceived causes and associated influential factors, which also reflects lay health literacy in this setting. Method Using 20 years of VA data (n=11,228) from the Agincourt Health and Demographic Surveillance System (HDSS) site in rural South Africa, we explored the agreement between the causes of death perceived by the VA-informants and those assigned by the automated Inter-VA tool. Kappa statistics and concordance correlation coefficients were applied to measure agreement at individual and population levels, respectively. Multivariable regression models were used to explore factors associated with recognised lay perceptions of causes of mortality. Results Agreement between informant-perceived and VA-derived causes of death at the individual level was limited, but varied substantially by cause of death. However, agreement at the population level, comparing cause-specific mortality fractions was higher, with the notable exception of bewitchment as a cause. More recent deaths, those in adults aged 15–49 years, deaths outside the home, and those associated with external causes showed higher concordance with InterVA. Conclusion Overall, informant perception of causes of death was limited, but depended on informant characteristics and causes of death, and to some extent involved non-biomedical constructs. Understanding discordance between perceived and recognised causes of death is important for public health planning; low community

    Full Text Available South Gujarat is endemic zone for leptospirosis in paddy workers but recently we have post flood plenty of urban patients who were presented with high grade fever, dyspnea & haemoptysis with rapid deterioration. Clinicians were suspecting an outbreak of Hantavirus or leptospirosis. Both our patients were serologically negative for leptospirosis ante mortem, but alveolar hemorrhage & raised urea was the only finding. Both our patient rapidly deteriorated. We performed autopsy & took post mortem samples for serologically & HP Examination of tissue. Serological finding showed one patient positive for PCR and second was positive for Leptocheck and IgM ELISA. On HP examination we observed massive intra-alveolar hemorrhage, interstitial nephritis, vasculitis in spleen and kidney, myocarditis & hemorrhage in various organs like heart, suprarenal gland, and subarachnoid space in both our patient. Levaditi’s stain was also performed but results were not conclusive. IHC for kidney tissue was not possible due to lack of facility. Extensive hemorrhage in lung was the cause of death in both patients. Follow up autopsy studies of 30 patients were showing same histopathological findings.

    Higuchi, Yujiro; Sakiyama, Yusuke; Nishihira, Yasushi; Endo, Kazuhiro; Suwazono, Shugo; Suehara, Masahito


    We report an autopsy case of a 74-year-old man with late onset Charcot-Marie-Tooth disease type 1A (CMT1A) diagnosed by genetic screening, later associated with amyotrophic lateral sclerosis (ALS). At the age of 70 years, the patient was admitted to our hospital because of progressive weakness and dysesthesia in the right upper limb. In the early stages of the illness, he was diagnosed with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), and transient improvement was achieved with intravenous immunoglobulin. However, the symptoms progressively worsened and became refractory. Gene analysis revealed PMP22 gene duplication, which confirmed CMT1A. On sural nerve biopsy, severe demyelinating neuropathy and abundant onion-bulb formations with endoneurial infiltration of inflammatory cells were observed. Thereafter, pseudo-bulbar palsy and respiratory muscle weakness developed insidiously and progressed rapidly along with muscle weakness in the limbs and trunk. The patient died about four years after the onset of this disease. Postmortem examination showed moderate neuronal cell loss, Bunina bodies, and TDP-43-positive inclusions in the anterior horn cells. The spinal cord revealed axonal loss and extensive macrophage permeation in the corticospinal tracts. On the basis of these findings, the final neuropathological diagnosis was ALS. This is the first report of an autopsy case of CMT1A complicated with ALS. We here discuss the significant clinical and neuropathological findings of this case.

  3. The clinico-pathological conference, based upon Giovanni Battista Morgagni's legacy, remains of fundamental importance even in the era of the vanishing autopsy. (United States)

    Zampieri, Fabio; Rizzo, Stefania; Thiene, Gaetano; Basso, Cristina


    Walter Cannon and Richard Cabot inaugurated the clinico-pathological conference (CPC) at Harvard Medical School at the beginning of the twentieth century, but this approach to anatomo-clinical correlation was first introduced by Giovanni Battista Morgagni at the University of Padua in the eighteenth century. The CPC consists of the presentation of a clinical case, in which past and recent medical histories of the patient, with all relevant information about laboratory tests including biopsy results, therapy and, eventually in a fatal case, the autopsy, are discussed. This is done for an audience of trainees and all physicians involved in the care for the patient. The CPC is still in use in many academic hospitals, as a teaching tool not only for undergraduate and graduate medical trainees, but also for postgraduate continuous medical education, in spite of the progressively declining autopsy rate. CPCs represent the ideal occasion for fruitful discussion between the two "souls" of medicine, i.e., the clinical, with its focus on the patient, and the pathological, with its focus on understanding disease. To discontinue using them would be equal to denying that modern medicine originated in Morgagni's method.

  4. Visualisation of the intact dura mater and brain surface in infant autopsies: a minimally destructive technique for the post-mortem assessment of head injury. (United States)

    Cheshire, Emma C; Malcomson, Roger D G; Rutty, Guy N; James, Deryk S


    During the post-mortem examination of babies and young children, it is important to be able to visualise the brain and its coverings, particularly in cases where a head injury is likely to have occurred. In this paper, we present an improved method for removal of the calvarial bones in infant autopsies to enable viewing of the dura mater and brain. In contrast to the standard post-mortem procedure for observing and removing the brain, this novel technique is minimally disruptive, allowing the dura mater to remain undamaged. Specialised paediatric neurosurgical tools were used to remove the skull bones from 23 neonates, infants and young children during post-mortem examination. In 21 of our 23 cases, the calvarial bones were removed successfully with the dura mater remaining intact. In one case, there was a thickening of the dura mater which created a strong adherence of this membrane to the bone. In another case, the dura mater was slightly damaged due to the inexperience of the operator in using the neurosurgical tools. This method of calvarial bone removal reduces the degree of post-mortem artefact and enhances the ability to observe and photographically document autopsy findings, including the artefact-free detection of signs of injury such as epidural or subdural haematoma, and brain swelling. This technique has now become a routine practise in both of our units to remove the skull bones in infant/young children post-mortem examinations.

  5. A qualitative inquiry into the application of verbal autopsy for a mortality surveillance system in a rural community of southern India. (United States)

    Mony, Prem K; Vaz, Mario


    The aim of this investigation was to identify operational and ethical issues encountered in the application of verbal autopsy (VA) in a rural community in south India. A qualitative study involving semi-structured interviews was conducted with 183 bereaved caregivers in rural Andhra Pradesh, India. Simple descriptive analysis was undertaken. Only 16% of adult deaths and 27% of child deaths occurred in healthcare settings. Healthcare utilization for the terminal illness was reported in two thirds of medical (non-injury) causes of death. Supporting medical evidence was available in <10% of cases to supplement the interpretation of verbal autopsies. About 14% of bereaved caregivers refused to give written consent but provided oral consent. Additional ethical concerns included inability to ensure privacy in 15% of interviews and unsolicited information from unauthorized neighbours in 5% of cases. Such methodological, logistical and ethical issues operate to impact on the quality of VAs. Consideration of these issues would strengthen ongoing efforts in the harmonization of VA procedures.

  6. Genotyping of Toxoplasma gondii: DNA extraction from formalin-fixed paraffin-embedded autopsy tissues from AIDS patients who died by severe disseminated toxoplasmosis. (United States)

    Bastos da Silva, Inara; Batista, Tatiana Pimental de Andrade; Martines, Roosecelis Brasil; Kanamura, Cristina Takami; Ferreira, Isabelle Martins Ribeiro; Vidal, Jose Ernesto; Pereira-Chioccola, Vera Lucia


    This study investigated the genetic features of Toxoplasma gondii isolated directly in autopsies of HIV-infected patients who died with severe disseminated toxoplasmosis. This retrospective analysis was conducted in a cohort of 15 HIV-infected patients with clinical and laboratory data. They had previous cerebral toxoplasmosis at least 6 months before the disseminated toxoplasmosis episode. The hypothesis was that they were infected with highly virulent parasites due to the condition in which they died. T. gondii genotyping was done directly in DNA extracted from 30 autopsy brain and lung samples (2 per patient) and mutilocus PCR-RFLP genotyping was done using 12 molecular markers. The 30 clinical samples were genotyped successfully in 8 or more loci and six suggestive genotypes were identified. One of them was Toxo DB #11, previously identified in different domestic animals and virulent in experimental animals. The other five suggestive genotypes identified in 14 patients were not described. TgHuDis1 was the most frequent and was determined in 8 patients. TgHuDis3 and TgHuDis5 were identified in two patients each. TgHuDis2 and TgHuDis4 have been identified in one patient each. These suggestive genotypes could be considered as virulent, since they caused severe tissue damage and had similar characteristics as Toxo # DB 11.

  7. Neuropathology of AIDS: An Autopsy Review of 284 Cases from Brazil Comparing the Findings Pre- and Post-HAART (Highly Active Antiretroviral Therapy and Pre- and Postmortem Correlation

Perinatal death in infants of less than 1 year old more frequently caused medical dispute than death

  9. Autopsy statistics on the relative frequency of acute myocardial infarction in the Japanese mental workers and the unemployed during the two oil-crises periods. (United States)

    Chang, N C; Kawai, S; Okada, R


    In order to investigate whether job induced emotional stress, arising from socioenvironmental disasters would act as a trigger for the onset of AMI, the author reviewed all pathological autopsies throughout Japan 15 years old and over. Data was obtained from publications of the "Annual of the Pathological Autopsy Cases in Japan" for the years 1966-1968 (a period of high economic growth), 1973-1975 (1974, the year of the first oil crisis), and 1978-1980 (1979, the year of the second oil crisis). Relative frequencies of AMI were significantly higher during the years of both oil crises than in both the preceding and following years (2.6% in 1973, 3.7% in 1974, 3.0% in 1975; 2.8% in 1978, 3.2% in 1979, and 2.0% in 1980), and in each of three years of the high economic growth period (1.9-2.2% in 1966-1968). The proportions of managers and officials among AMI victims were significantly higher in the years of both oil crises than in both the preceding and following years (13.4% in 1973, 17.5% in 1974, 12.5% in 1975; 11.6% in 1978, 15.8% in 1979, and 11.1% in 1980). Moreover, there was a significantly higher value in the year of first oil crisis than in each of three years of the high economic growth period (11.7-13.1% in 1966-1968). The proportions of "out of job" persons were also significantly higher in the years of both oil crises than in the preceding years (24.0% in 1973, 29.3% in 1974, 27.8% in 1975; 24.1% in 1978, 29.1% in 1979, and 27.4% in 1980). For 11,199 randomly selected autopsies, the proportions of AMI in the above two occupational groups were significantly higher in the years of both oil crises than in the preceding years. Moreover, the proportion of "out of job" persons was significantly higher in the year of first oil crisis than in each of three years of the high economic growth period. A similar trend was noted among professional and technical workers, with more AMI occurring in this group during the years of both oil crises than in both the preceding

    An 81-year-old Japanese man with jaundice was strongly suspected clinically of having primary sclerosing cholangitis based on clinical examinations and later died of hepatic failure. The entire course of the disease lasted about 10 mo. The autopsy revealed extensive fibrinoid necrosis in the liver, kidney, spleen, pancreas,lung, lymph nodes, and pleura. Particularly extensive fibrinoid necrosis in the portal tracts of the liver induced severe stenoses of the intrahepatic bile ducts, resulting in cholestasis in association with prominent liver injury.There were no findings indicating primary sclerosing cholangitis. The hepatic lesions in this case did not coincide with any known disease including collagen diseases. To clarify the cause of irregular stenoses of the intrahepatic biliary trees on cholangiographic findings, we postulate that some form of immunological derangement might be involved in pathogenesis of fibrinoid necrosis.However, the true etiology remains unknown.

  11. Suicide by antidepressant intoxication identified at autopsy in Vienna from 1991-1997: the favourable consequences of the increasing use of SSRIs. (United States)

    Frey, R; Schreinzer, D; Stimpfl, T; Vycudilik, W; Berzlanovich, A; Kasper, S


    In the area of Vienna, any person dying under questionable circumstances is examined at the Institute of Forensic Medicine, where the cause of death is determined by means of autopsy and chemical analysis. Our study on fatal intoxications was performed in the period between 1991 and 1997, when selective serotonin reuptake inhibitors (SSRIs) were establishing themselves on the market, reaching the top of prescription statistics. Tricyclic antidepressants (TCAs) were involved in 30 single- and 127 multiple-substance intoxications, with amitriptyline and doxepin being the most frequently used drugs. SSRIs were involved in five multiple-substance intoxications. The f-value, which refers to the number of deaths per million defined daily doses prescribed, was found to be significantly (Pantidepressants declined significantly (Pantidepressants did not coincide with an increased number of deaths caused by these drugs.

  12. An autopsy report case of rape victim by the application of PSA test kit as a new innovation for sexual assault investigation in Thailand. (United States)

    Talthip, Jate; Chirachariyavej, Thamrong; Peonim, A V M Vichan; Atamasirikul, Kalayanee; Teerakamchai, Somsri


    The case of a 30 year-old Thai female found dead on the floor at the base of a small monument on Rajadumnern Road, Bangkok, Thailand with blood stains around the body and a naked bottom. The scene investigation and autopsy findings suggested a sexual assault and multiple sharp force injuries. The approach to the postmortem examination using different laboratory tests is reviewed. The specificity and sensitivity of prostate specific antigen (PSA) in specimens from rape victims is better than acid phosphatase test. The ELISA test for PSA was tested to confirm the PSA test kit. The present report suggests the PSA test kit in addition to conventional sperm smear and acid phosphatase test for sexual assault investigation in Thailand.

  13. [The impact of methodology on the reported prevalence of thyroid pathology: comparison of two autopsy series from Switzerland performed with different methods]. (United States)

    Fleischmann, A; Hardmeier, Th


    To investigate the impact of methodology on the detection and hence reported prevalence of pathological findings in thyroids, in the geographic area of Kt. Thurgau in Switzerland, we used two different methods in two consecutive autopsy series of 420 patients. In series A, the thyroids were sliced unfixed and only suspect lesions were examined histologically. In series B, the thyroids were fixed in formalin and sectioned in a standardized manner. At least one specimen per lobe was taken for histological examination. Series A revealed that five patients had adenomas, four malignant primary tumors, two metastases and four inflammatory changes in the thyroid. Series B detected ten patients with adenomas, eight with primary malignant tumors, eleven with metastases and twenty-eight with inflammatory changes in the thyroid. These differences were significant (p < 0.001). In conclusion, the methodology has an important impact on the detected prevalence of pathological findings in the thyroid.

  14. Anomalous origin of the right coronary artery from the pulmonary artery: an autopsied sudden death case with severe atherosclerotic disease of the left coronary artery. (United States)

    Nagai, T; Mukai, T; Takahashi, S; Takada, A; Saito, K; Harada, K; Mori, S; Abe, N


    Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a rare anomaly. It may contribute to myocardial ischemia or sudden death, although the lesion is usually asymptomatic. We report a sudden death case of a 58-year-old man with ARCAPA coexisting with severe atherosclerotic coronary artery disease. He had been healthy until he complained of chest pain, several days before death, despite the discovery of heart murmur in childhood and suspicion of valvular heart disease. The autopsy revealed not only typical findings of the right coronary anomaly with well-developed collateral circulations but also severe atherosclerotic lesions of the left coronary artery, and ischemic change of the myocardium in the left and right coronary arterial perfusion territory. In addition to the "coronary steal" phenomenon primarily caused by ARCAPA, the reduced flow of both coronary arteries and further increase of "coronary steal" due to atherosclerotic obstructive coronary disease might have contributed to the patient's death.

  15. (13)Carbon and (15)nitrogen isotopes in autopsy liver tissue samples from Greenlandic Inuit and Danes: consumption of marine versus terrestrial food

    DEFF Research Database (Denmark)

    Milman, N.; Laursen, J.; Mulvad, G.


    Background/Objectives: The content of C-13 and N-15 isotopes is higher in marine than in terrestrial food. C-13 and N-15 in human tissue therefore reflects the relative proportions of marine and terrestrial food consumed by the individual. The objective of this study was to measure C-13 and N-15...... in liver tissue from Greenlandic Inuit and Danes. Subjects/Methods: Normal liver tissue was obtained at autopsy in 1992-1994 from 60 Inuit with a median age of 61 years (range 25-83) and in 1986 from 15 ethnic Danes with a median age of 84 years (range 66-93). By sieving, liver tissue was separated...

  16. An autopsy case of acute cor pulmonale and paradoxical systemic embolism due to tumour cell microemboli in a patient with breast cancer. (United States)

    Uga, Sayuri; Ikeda, Shuntaro; Matsukage, Sho-ichi; Hamada, Mareomi


    A 62-year-old woman was admitted to our hospital because of severe respiratory distress. Diagnostic imaging studies suggested the existence of inexplicable cor pulmonale. Although we immediately sought the aetiology of her severe condition, she died suddenly on the fourth day after admission. Postmortem autopsy revealed tumour cell microemboli in the small pulmonary arteries. In addition, tumour cell embolisation identical to that in primary breast cancer cells was also observed in microvessels in systemic multiple organs, such as the liver, brain, kidneys, spleen, uterus, bone marrow and adrenal glands-with simultaneous findings of peripheral infarction. Systemic tumour cell embolism mediated through the patent foramen ovale superimposed on pulmonary tumour cell emboli (PTCE) is considered to be the mechanism underlying inexplicable cor pulmonale. The rapid aggravation of her condition terminated in death.

  17. Degree of abnormality is associated with rate of change in measures of beta-amyloid, glucose metabolism and cognition in an autopsy-verified Alzheimer's disease case. (United States)

    Almkvist, Ove; Kadir, Ahmadul; Nordberg, Agneta


    The degree of abnormality and rate of change in cognitive functions, positron emission tomography Pittsburg compound B (PET PIB), and fluorodeoxyglucose (FDG) measures were studied for 8 years in an autopsy-confirmed Alzheimer's disease (AD) patient, who died 61 years old (Mini-Mental State Examination (MMSE) score 7). At first encounter with medical care, the patient was very mildly demented (MMSE score 27). She had four cognitive assessments and two examinations with PET PIB and FDG in 23 bilateral brain regions. The onset of cognitive decline was retrospectively estimated to have started in the early forties. The degree of impairment was inversely related to the rate of decline. A similar relationship was seen between the rate of change and the level of abnormality in both PIB and FDG. To conclude, rate of change in cognition, PIB, and FDG was associated with the degree of abnormality.

  18. Ability of combined Near-Infrared Spectroscopy-Intravascular Ultrasound (NIRS-IVUS) imaging to detect lipid core plaques and estimate cap thickness in human autopsy coronary arteries (United States)

    Grainger, S. J.; Su, J. L.; Greiner, C. A.; Saybolt, M. D.; Wilensky, R. L.; Raichlen, J. S.; Madden, S. P.; Muller, J. E.


    The ability to determine plaque cap thickness during catheterization is thought to be of clinical importance for plaque vulnerability assessment. While methods to compositionally assess cap integrity are in development, a method utilizing currently available tools to measure cap thickness is highly desirable. NIRS-IVUS is a commercially available dual imaging method in current clinical use that may provide cap thickness information to the skilled reader; however, this is as yet unproven. Ten autopsy hearts (n=15 arterial segments) were scanned with the multimodality NIRS-IVUS catheter (TVC Imaging System, Infraredx, Inc.) to identify lipid core plaques (LCPs). Skilled readers made predictions of cap thickness over regions of chemogram LCP, using NIRS-IVUS. Artery segments were perfusion fixed and cut into 2 mm serial blocks. Thin sections stained with Movat's pentachrome were analyzed for cap thickness at LCP regions. Block level predictions were compared to histology, as classified by a blinded pathologist. Within 15 arterial segments, 117 chemogram blocks were found by NIRS to contain LCP. Utilizing NIRSIVUS, chemogram blocks were divided into 4 categories: thin capped fibroatheromas (TCFA), thick capped fibroatheromas (ThCFA), pathological intimal thickening (PIT)/lipid pool (no defined cap), and calcified/unable to determine cap thickness. Sensitivities/specificities for thin cap fibroatheromas, thick cap fibroatheromas, and PIT/lipid pools were 0.54/0.99, 0.68/0.88, and 0.80/0.97, respectively. The overall accuracy rate was 70.1% (including 22 blocks unable to predict, p = 0.075). In the absence of calcium, NIRS-IVUS imaging provided predictions of cap thickness over LCP with moderate accuracy. The ability of this multimodality imaging method to identify vulnerable coronary plaques requires further assessment in both larger autopsy studies, and clinical studies in patients undergoing NIRS-IVUS imaging.

  19. Herpes simplex encephalitis (HSE) and the immunocompromised: a clinical and autopsy study of HSE in the settings of cancer and human immunodeficiency virus-type 1 infection. (United States)

    Schiff, D; Rosenblum, M K


    Although herpes simplex encephalitis (HSE) is not regarded as an opportunistic infection, the occurrence of HSE in immunocompromised patients has been documented and the suggestion made that unusual clinical and neuropathologic features characterize the disorder in this population. To further characterize HSE as it affects the immunodeficient, the authors reviewed the clinical and pathological findings in three immunocompromised patients with autopsy-proven HSE. Two patients had cancer (one with lymphoma and another with glioblastoma multiforme), one was known to be human immunodeficiency virus-type 1 (HIV-1)-seropositive and a second was suspected of harboring underlying HIV-1 infection. Two were receiving dexamethasone at onset of HSE. All had fever, mental status changes and new, focal neurological deficits or worsening of established deficits. Cerebrospinal fluid (CSF) pleocytosis was absent or minimal and head computerized tomographic (CT) scans, performed in all cases, were unrevealing. No patient was clinically suspected of having HSE, only one received acyclovir (for concurrent mucocutaneous herpes) and HSE played a major role in all deaths. Autopsy revealed an unusual form of HSE characterized by a noninflammatory, pseudoischemic histological presentation and the unexpected persistence of viral antigens in abundance despite survival beyond the clinical stage during which inflammatory responses usually peak and productive brain infection wanes. The incidence of HSE in the immunocompromised may be underestimated. Preexistent neurological disease, a noninflammatory CSF profile and negative CT scan may confound the diagnosis in this population, a typical clinical presentation notwithstanding. Increased clinical suspicion, the use of magnetic resonance imaging and polymerase chain reaction analysis of CSF for herpes simplex virus nucleic acid sequences may permit more rapid diagnosis and treatment. The absence of inflammatory infiltrates in some fatal cases of

  20. Postmortem volumetric CT data analysis of pulmonary air/gas content with regard to the cause of death for investigating terminal respiratory function in forensic autopsy. (United States)

    Sogawa, Nozomi; Michiue, Tomomi; Ishikawa, Takaki; Kawamoto, Osamu; Oritani, Shigeki; Maeda, Hitoshi


    Postmortem CT (PMCT) is useful to investigate air/gas distribution and content in body cavities and viscera. The present study investigated the procedure to estimate total lung air/gas content and aeration ratio as possible indices of terminal respiratory function, using three-dimensional (3-D) PMCT data analysis of forensic autopsy cases without putrefactive gas formation (within 3 days postmortem, n=75), and analyzed the volumetric data with regard to the cause of death. When 3-D bilateral lung images were reconstructed using an image analyzer, combined lung volume was larger in drowning (n=12) than in alcohol/sedative-hypnotic intoxication (n=8) and sudden cardiac death (SCD; n=10), and intermediate in other cases, including mechanical asphyxiation (n=12), fire fatalities due to burns (n=6) and carbon monoxide intoxication (n=7), fatal methamphetamine abuse (n=7), hyperthermia (heatstroke; n=6) and fatal hypothermia (cold exposure; n=7). Air/gas content of the lung as detected using HU interval between -2000 and -400 ('effective' lung aeration areas) and between -2000 and -191 (total lung aeration areas) as well as the ratios to total lung volume ('effective' and total lung aeration ratios, respectively) was higher in mechanical asphyxiation, drowning, fatal burns and hypothermia (cold exposure) than in SCD, and was intermediate in other cases. 'Effective' and total lung aeration ratios may be useful for comparisons between specific causes of death to discriminate between hypothermia (cold exposure) and drug intoxication, and between SCD and other causes of death, respectively. These findings provide interesting insights into potential efficacy of PMCT data analyses of lung volume and CT density as well as lung air/gas content and aeration ratio with regard to the cause of death, as possible indicators of terminal respiratory function, as part of virtual autopsy of the viscera in situ.

  1. Post-mortem Whole exome sequencing with gene-specific analysis for autopsy-negative sudden unexplained death in the young: a case series. (United States)

    Narula, Nupoor; Tester, David J; Paulmichl, Anna; Maleszewski, Joseph J; Ackerman, Michael J


    Annually, thousands of sudden deaths in individuals under 35 years remain unexplained following comprehensive medico-legal autopsy. Previously, post-mortem genetic analysis by Sanger sequencing of four major cardiac channelopathy genes revealed that approximately one-fourth of these autopsy-negative sudden unexplained death in the young (SUDY) cases harbored an underlying mutation. However, there are now over 100 sudden death-predisposing cardiac channelopathy-, cardiomyopathy-, and metabolic disorder-susceptibility genes. Here, we set out to determine whether post-mortem whole exome sequencing (WES) is an efficient strategy to detect ultra-rare, potentially pathogenic variants. We performed post-mortem WES and gene-specific analysis of 117 sudden death-susceptibility genes for 14 consecutively referred Caucasian SUDY victims (average age at death 17.4 ± 8.6 years) to identify putative SUDY-associated mutations. On average, each SUDY case had 12,758 ± 2,016 non-synonymous variants, of which 79 ± 15 localized to these 117 genes. Overall, eight ultra-rare variants (seven missense, one in-frame insertion) absent in three publically available exome databases were identified in six genes (three in TTN, and one each in CACNA1C, JPH2, MYH7, VCL, RYR2) in seven of 14 cases (50 %). Of the seven missense alterations, two (T171M-CACNA1C, I22160T-TTN) were predicted damaging by three independent in silico tools. Although WES and gene-specific surveillance is an efficient means to detect rare genetic variants that might underlie the pathogenic cause of death, accurate interpretation of each variant is challenging. Great restraint and caution must be exercised otherwise families may be informed prematurely and incorrectly that the root cause has been found.

  2. The autopsy archive of former uranium miners of the East German WISMUT company - a valuable resource for research on ionizing radiation in interaction with other carcinogens and cancer

    Energy Technology Data Exchange (ETDEWEB)

    Pesch, B.; Taeger, D. [Berufsgenossenschaftliches Forschungsinstitut fuer Arbeitsmedizin (BGFA), Univ. of Bochum (Germany); Wiethege, T. [Inst. of Pathology of Ruhr Univ., Kliniken Bergmannsheil, Bochum (Germany)


    In East Germany, uranium mining was undertaken on a large scale for the Soviet nuclear industry from 1946 to 1989. Poor working conditions especially in the early years led to a high level of occupational diseases, in particular lung cancer. For WISMUT miners, comprehensive data is available on working histories and exposure to radiation and quartz dust. After German reunification, the autopsy archive of the Institute of Pathology in Stollberg was opened for research as part of the WISMUT Health Data Archive of the Bundesanstalt fuer Arbeitsschutz und Arbeitsmedizin. It contains protocols of about 30,000 persons (including 17,000 miners), 400,000 slides, 66,000 tissue blocks, and 200 whole lungs. Now, the tissue repository is held in trust at BGFA and Institute of Pathology in Bochum, Germany. The source population of the cases is not defined. The archive contains tissues from many - but not from all - former WISMUT miners as well as from local people. For 12,923 miners, median radon exposure was 621 WLM, including about 800 workers with exposure above 1800 WLM. Smoking information is poor, but prevalence of smoking was high. A leading diagnosis was lung cancer in about 5,300 persons, mainly underground miners. A database has been developed at Deutsches Krebsforschungszentrum to document relevant autopsy information on the cases. Histopathological classification of 5,270 lung cancer cases has been re-assessed by three pathologists. U.S. NIOSH conducted a study on the feasibility of research on pathologic types of lung cancer. Laboratory studies on the quality of the material for molecular-biological investigations are under way. A project is ongoing to investigate the interaction of radiation and crystalline silica on lung cancer development. A workshop was scheduled December 10, 2004 to discuss the resources, the findings, the pitfalls and challenges presented by the material and the future use of that archive in research. (orig.)

  3. Is Urinary Lipoarabinomannan the Result of Renal Tuberculosis? Assessment of the Renal Histology in an Autopsy Cohort of Ugandan HIV-Infected Adults.

    Directory of Open Access Journals (Sweden)

    Janneke A Cox

    Full Text Available The detection of urinary lipoarabinomannan (LAM, a mycobacterial cell wall component, is used to diagnose tuberculosis (TB. How LAM enters the urine is not known. To investigate if urinary LAM-positivity is the result of renal TB infection we correlated the outcomes of urinary LAM-antigen testing to renal histology in an autopsy cohort of hospitalized, Ugandan, HIV-infected adults.We performed a complete autopsy, including renal sampling, in HIV-infected adults that died during hospitalization after written informed consent was obtained from the next of kin. Urine was collected postmortem through post-mortem catheterisation or by bladder puncture and tested for LAM with both a lateral flow assay (LFA and an ELISA assay. Two pathologists assessed the kidney histology. We correlated the LAM-assay results and the histology findings.Of the 13/36 (36% patients with a positive urinary LAM ELISA and/or LFA, 8/13 (62% had renal TB. The remaining 5 LAM-positive patients had disseminated TB without renal involvement. Of the 23 LAM-negative patients, 3 had disseminated TB without renal involvement. The remaining LAM-negative patients had no TB infection and died mostly of fungal and bacterial infections. LAM LFA had a sensitivity of 81% and specificity of 100% to diagnose TB at any location, and the LAM ELISA a sensitivity of 63% and a specificity of 100%. 54% (7/13 LAM LFA-positive patients were not on anti-TB treatment at the time of death.Renal TB infection explained LAM-positivity in the majority of patients. Patients with disseminated TB without renal involvement can also be diagnosed with LAM. This suggests that other mechanisms that lead to urinary LAM-positivity exist in a minority of patients.

  4. Evaluation of combined near-IR spectroscopic (NIRS)-IVUS imaging as a means to detect lipid-rich plaque burden in human coronary autopsy specimens (United States)

    Su, Jimmy L.; Grainger, Stephanie J.; Greiner, Cherry A.; Hendricks, Michael J.; Goode, Meghan M.; Saybolt, Matthew D.; Wilensky, Robert L.; Madden, Sean P.; Muller, James E.


    Intracoronary near-infrared spectroscopy (NIRS) can identify lipid in the coronary arteries, but lacks depth resolution. A novel catheter is currently in clinical use that combines NIRS with intravascular ultrasound (IVUS), which provides depth-resolved structural information via the IVUS modality. A measure designated as lipid-rich plaque burden (LRPB) has been proposed as a means to interpret the combined acoustic and optical information of NIRS-IVUS. LRPB is defined as the area created by the intersection of the NIRS lipid-rich arc with the corresponding IVUS-measured plaque burden. We determined the correlation in human coronary autopsy specimens between LRPB, a measure of lipid presence and extent available via intravascular imaging in patients, and the area of lipid-rich plaque as determined by the gold-standard of histology. Fifteen artery segments from 8 human autopsy hearts were imaged with the NIRS-IVUS system (TVC Imaging System, Infraredx Inc., Burlington, MA). Arteries were imaged in a specialty fixture that assured accurate co-registration between imaging and histology. The arteries were then fixed and divided into 2 mm blocks for histological staining. Pathological contouring of lipid-rich areas was performed on the stained thin sections for 54 lipid-rich blocks. Computation of LRPB was performed on transverse NIRS-IVUS frames corresponding to the histologic sections. The quantified LRPB was frequently higher than the lipid-rich plaque area determined by histology, because the region denoted by the EEL and lumen within the NIRS lipid-rich arc is not entirely comprised of lipid. Overall, a moderate to strong correlation (R = 0.73) was found between LRPB determined by NIRS-IVUS imaging and the lipid-rich plaque area determined by histology. LRPB, which can be measured in patients with NIRS-IVUS imaging, corresponds to the amount of lipid-rich plaque in a coronary artery. LRPB should be evaluated in prospective clinical trials for its ability to

    Full Text Available Background: The statistical profile reflects a global estimate of 5.1 million deaths in 2000, which was due to injuries that accounted for 10% of deaths due to all causes. Out of this, a quarter of injury-related deaths occurred in the South-East Asian region. Road Traffic Accident (RTA is one among the top 5 causes of morbidity and mortality in South-East Asian countries. Most common cause of blunt abdominal trauma in India is road traffic accident followed by pedestrian accidents, abdominal blows, and fall from heights. Aims: To analyze the epidemiology and pattern of fatal thoraco-abdominal injuries in road traffic accidents. Materials and Methods: An autopsy-based cross-sectional study conducted. A purposive sampling technique was applied to select the study sample of 100 post-mortems of road traffic accident between November 2008 and May 2010 subjected to medico-legal autopsy at the department of Forensic Medicine, KIMS Hospital Bangalore. Results: The majority of the victims were aged 21 to 40 years, 50 (50.0%, most of the victims were male 92 (92.0%; and male/female ratio was 11.5:1. Commonest offending agents in heavy motor vehicles were 54 (54.0%. Bony cage sustained injuries were observed in 71; out of this, fractures of ribs were observed in 45 (63.3% victims, clavicle in 14 (19.7%, sternum was 6 (8.4%, and vertebrae 6 (8.4% of fatal road traffic accidents. Internal thoracic injuries were observed in 26 cases. Among internal thoracic injuries, lungs were the most commonly involved organ 24 (92.3% followed by the heart 2 (7.6%. Lung sustained more lacerations 19 (79.1% than contusions 5 (20.8%. Internal abdominal injuries were observed in 49 cases. In road traffic accidents, the most commonly injured abdominal organs were solid organs such as liver 16 (32.6% followed by spleen 9 (18.3%. Conclusions: Majority of the times in road traffic accidents, young and productive males were injured or lost their life. This study may help the

  7. Detection of Mercury in Human Organs and Hair in a Case of a Homicidal Poisoning of a Woman Autopsied 6 Years After Death. (United States)

    Lech, Teresa


    In the described case of the death of a 53-year-old woman, no toxicological examination was performed directly after death (only an anatomopathological autopsy), although symptoms of serious gastrointestinal disturbances had been present (the woman had been hospitalized twice in the course of several months). It was assumed that the cause of death was myocardial infarction. Five years later, some new circumstances came to light which suggested that somebody could have administered some poison (metals, cyanides) to the woman. Toxicological analysis of postmortem samples from the corpse, exhumed 6 years after death by order of the public prosecutor's office, revealed high tissue mercury contents in biological material (cold vapor atomic absorption spectrometry): small intestine, 1516 ng/g; large intestine, 487 ng/g; liver, 1201 ng/g; heart muscle, 1023 ng/g; and scalp hair, 227 ng/g. In samples of soil from places near the coffin, negligible traces of mercury were found (0.5-1.5 ng/g); contamination by mercury from the environment was ruled out. The presented case is a rare example of recognition of mercury poisoning on the basis of the results of analysis of biological material from an exhumed cadaver.

    Full Text Available Background: Cause of death data is necessary for arranging health programs. The needs of these data is not fulfill yet through reporting and recording system from health facilities only,therefore national health survei should be conducted regularly. Objective: To obtain cause of death trends in the populations from VA data. Methods: Material taken from Nasional Health Survey 1992, 1995, 2001, 2007 covering 65,664 households (HH, 206,240 HH, 211,168 HH, 258,366 HH respectively, selected by stratified random sampling technique using core and module sample of Socio Economic National Survey (Susenas and taken with a Probability Proportional to Size method. Cause of death data was collected by structured questionnaire using verbal autopsy (VA technique and was classified based on ICD 9 and ICD 10. Results: The disease patterns of cause of death from 1992 to 2007 showed the non-communicable disease is increasing continuously while communicable disease (infectious, maternal and perinatal, nutritional deficiencies is decreasing; however the burden of disease is still present on both groups of diseases. Conclusions: The little bit less accurate VA data (1992–2007 collected is able to produce national statistic data of cause of death and could be used to suggest health planning program managers in Indonesia

  9. Human cranial vault thickness in a contemporary sample of 1097 autopsy cases: relation to body weight, stature, age, sex and ancestry. (United States)

    De Boer, H H Hans; Van der Merwe, A E Lida; Soerdjbalie-Maikoe, V Vidija


    The relation between human cranial vault thickness (CVT) and various elements of the physical anthropological biological profile is subject of ongoing discussion. Some results seem to indicate no correlation between CVT and the biological profile of the individual, whereas other results suggest that CVT measurements might be useful for identification purposes. This study assesses the correlation between CVT and body weight, stature, age, sex, and ancestry by reviewing data of 1097 forensic autopsies performed at the Netherlands Forensic Institute (NFI). In subadults (younger than 19 years of age at the time of death), all frontal, temporal, and occipital CVT measurements correlated moderately to strongly with indicators of growth (body weight, stature, and age). Neither sex nor ancestry correlated significantly with cranial thickness. In adults, body weight correlated with all CVT measurements. No meaningful correlation was found between CVT and stature or age. Females showed to have thicker frontal bones, and the occipital region was thicker in the Negroid subsample. All correlation in the adult group was weak, with the distribution of cranial thickness overlapping for a great deal between the groups. Based on these results, it was concluded that CVT generally cannot be used as an indicator for any part of the biological profile.

  10. The relationship between impulsivity and suicide among rural youths aged 15-35 years: a case-control psychological autopsy study. (United States)

    Lin, Lin; Zhang, Jie; Zhou, Li; Jiang, Chao


    In China, the gender ratio of suicide rates did not match the Western patterns, which was higher for females than males. However, the rural men were at relatively high risk of suicide in Liaoning province. Impulsivity was an important factor of suicide behaviors, but there was a lack of studies in China. This research aimed to study the relationship between impulsive personality traits and suicidal behavior among Chinese rural youths. Suicides were consecutively sampled from six randomly selected counties in Liaoning Province in China. Between 2005 and 2007, a total of 162 suicide victims were enrolled in the study along with 162 community controls matched for age, gender, and location. The psychological autopsy method was used to collect data from informants knowledgeable about the selected suicide victims and controls. The results showed the suicide victims in the study were more likely to demonstrate dysfunctional impulsivity and less likely to demonstrate functional impulsivity compared with the controls. Mental disorders, acute negative life events, and dysfunctional impulsivity contributed to the risk of suicide; educational and functional impulsivity were protective factors. Suicide prevention efforts in rural China may address impulsivity.

    The objective of this study was to evaluate and compare the complications of cardiopulmonary resuscitation after manual or mechanical chest compressions in a swine model of ventricular fibrillation. In this retrospective study, 106 swine were treated with either manual (n=53) or mechanical chest compressions with the LUCAS device (n=53). All swine cadavers underwent necropsy. The animals with no autopsy findings were significantly fewer in the LUCAS group (P=0.004). Sternal fractures were identified in 18 animals in the manual and only two in the LUCAS group (P=0.003). Rib fractures were present in 16 animals in the manual and only four in the LUCAS group (P=0.001). Nine animals in the manual, and two in the LUCAS group had liver hematomas (P=0.026%). In the manual group, eight animals were detected with spleen hematomas whereas no such injury was identified in the LUCAS group (P=0.003). LUCAS devise minimized the resuscitation-related trauma compared with manual chest compressions in a swine model of cardiac arrest.

  12. Reactive Astrocytes Expressing Intense Estrogen Receptor-alpha Immunoreactivities Have Much Elongated Cytoplasmic Processes: An Autopsy Case of Human Cerebellar Tissue with Multiple Genitourinary and Gastrointestinal Anomalies (United States)

    Kim, Eo-Jin; Oh, Chang Seok; Kim, Jaehyup; Kim, Wu Ho; Chung, Yoon Hee


    We performed an immunohistochemical study on the estrogen receptor alpha (ER-α) distribution in the cerebellum of a human neonate with multiple congenital anomalies, that had been acquired during autopsy. Although the exact pathology in the brain was not clearly elucidated in this study, an unidentified stressful condition might have induced the astrocytes into reactive states. In this immunohistochemical study on the neonatal cerebellum with multiple congenital anomalies, intense ER-α immunoreactivities (IRs) were localized mainly within the white matter even though ER-α IRs were known to be mainly localized in neurons. Double immunohistochemical staining showed that ER-α IR cells were reactive astrocytes, but not neurons. Interestingly, there were differences in the process length among the reactive astrocytes showing ER-α IRs. Our quantitative data confirmed that among the glial fibrillary acidic protein (GFAP)-expressing reactive astrocytes, the cells exhibiting intense ER-α IRs have much longer cytoplasmic processes and relatively weaker GFAP IRs. Taken together, the elongated processes of reactive astrocytes might be due to decreased expression of GFAP, which might be induced by elevated expression of ER-α even though the elucidation of the exact mechanism needs further studies.

  13. Pulmonary hypoplasia on preterm infant associated with diffuse chorioamniotic hemosiderosis caused by intrauterine hemorrhage due to massive subchorial hematoma: report of a neonatal autopsy case. (United States)

    Yamada, Sohsuke; Marutani, Takamitsu; Hisaoka, Masanori; Tasaki, Takashi; Nabeshima, Atsunori; Shiraishi, Mika; Sasaguri, Yasuyuki


    A male infant born prematurely at 31 weeks of gestation weighed 789 g and had mildly brown-colored oral/tracheal aspirates at delivery. The amniotic fluid was also discolored, and its index was below 5. The patient died of hypoxemic respiratory and cardiac failure 2 hours after birth. The maternal profiles showed placenta previa and intrauterine growth restriction (IUGR) at 22 weeks of gestation, and revealed recurrent episodes of antenatal and substantial vaginal bleeding and oligohydramnios, indicating chronic abruption-oligohydramnios sequence. The thickened placenta, weighing 275 g, grossly displayed unevenness and diffuse opacity with green to brown discoloration in the chorioamniotic surface, and revealed chronic massive subchorial hematomas (Breus' mole) with old peripheral blood clot, circumvallation, and infarction. Microscopically, diffuse Berlin-blue staining-positive hemosiderin deposits were readily encountered in the chorioamniotic layers of the chorionic plate, consistent with diffuse chorioamniotic hemosiderosis (DCH) due to Breus' mole, accompanied by diffuse amniotic necrosis. At autopsy, an external examination showed several surface anomalies and marked pulmonary hypoplasia, 0.006 (less 0.012) of lung:body weight ratio. Since Breus' mole has a close relationship with intrauterine hemorrhage, resulting in DCH, IUGR, and/or pulmonary hypoplasia of the newborn, the present features might be typical.

  14. Contribution of forensic autopsy to scene reconstruction in mass fire casualties: a case of alleged arson on a floor consisting of small compartments in a building. (United States)

    Michiue, Tomomi; Ishikawa, Takaki; Oritani, Shigeki; Maeda, Hitoshi


    A fire is an important cause of mass disasters, involving various forensic issues. Before dawn on an early morning, 16 male visitors in their twenties to sixties were killed in a possibly incendiary fire at a 'private video parlor' consisting of small compartments in a building. The main causes of death as determined by forensic autopsy were acute carbon monoxide (CO) intoxication for all of the 15 found-dead victims, and hypoxic-ischemic encephalopathy following acute CO intoxication for a victim who died in hospital. Burns were mild (victims, except for three victims found between the entrance and the estimated fire-outbreak site; thus, identification was completed without difficulty, supported by DNA analysis. Blood carboxyhemoglobin saturation (COHb) was higher for victims found dead in the inner area. Blood cyanide levels were sublethal, moderately correlated to COHb, but were higher in victims found around the estimated fire-outbreak site. There was no evidence of thinner, alcohol or drug abuse, or an attack of disease as a possible cause of an accidental fire outbreak. These observations contribute to evidence-based reconstruction of the fire disaster, and suggest how deaths could have been prevented by appropriate disaster measures.

  15. In-depth analyses of organic matters in a full-scale seawater desalination plant and an autopsy of reverse osmosis membrane

    KAUST Repository

    Jeong, Sanghyun


    In order to facilitate the global performance of seawater reverse osmosis (SWRO) systems, it is important to improve the feed water quality before it enters the RO. Currently, many desalination plants experience production losses due to incidents of organic and biofouling. Consequently, monitoring or characterizing the pretreatment step using more advanced organic and biological parameters are required for better operation to lessen fouling issues. In this study, the performance of pretreatment processes (including coagulation, dual media filtration (DMF), polishing with cartridge filter (CF) coupled with anti-scalant) used at Perth Seawater Desalination Plant (PSDP) located in Western Australia were characterized in terms of organic and biological fouling parameters. These analyses were carried out using liquid chromatography with organic carbon detector (LC-OCD), three dimensional-fluorescence excitation emission matrix (3D-FEEM) and assimilable organic carbon (AOC). Furthermore, the used (exhausted) RO membrane and CF were autopsied so that the fates and behaviors of organic foulants in these treatment systems could be better understood.

  16. Suicide or accident? A psychological autopsy study of suicide in youths under the age of 16 compared to deaths labeled as accidents

    Directory of Open Access Journals (Sweden)

    Freuchen Anne


    Full Text Available Abstract Objective In the present paper, we describe suicide in youths under 16 years of age and compare their risk factors for suicide to those of older adolescents as described in the literature. Furthermore, we evaluate the possible mislabeling of suicides as accidents, and vice versa. Method We used the data from a nationwide psychological autopsy of youths 15 years and younger who had committed suicide or died in accidents in Norway from 1993 to 2004 (n = 84. We additionally constructed a suicide index to distinguish between the two causes of death. Results The young suicide victims presented, with little gender difference, fewer obvious risk factors and less suicide intent than commonly described for older adolescents. The suicide index distinguished quite well between suicides and accidents, with few cases indicating a possible mislabeling, although some suicide cases could have been labeled as uncertain. Conclusion In line with previous research, suicides in 11-15-year-olds have many similarities to suicides in older adolescents in terms of external circumstances, but they present less apparent warning signs. In our total sample of 84 deaths, there were few indications of incorrect labeling.

  17. Prevalence of thyroiditis and immunohistochemistry study searching for a morphologic consensus in morphology of autoimmune thyroiditis in a 4613 autopsies series. (United States)

    Vecchiatti, Stella M P; Lin, Chin Jia; Capelozzi, Vera L; Longatto-Filho, Adhemar; Bisi, Hélio


    We sought to verify the prevalence of lymphocytic thyroiditis (LT) and Hashimoto's thyroiditis (HT) in autopsy materials. Cases examined between 2003 and 2007 at the Department of Pathology of Faculty of Medicine of São Paulo University were studied. Immunohistochemical analyses were conducted in selected cases to characterize the type of infiltrating mononuclear cells; in addition, we evaluated the frequency of apoptosis by TUNEL assay technique and caspase-3 immunostaining. Significant increase in overall thyroiditis frequency was observed in the present series when compared with the previous report (2.2978% vs. 0.0392%). Thyroiditis was more prevalent among older people. Selected cases of LT and HT (40 cases each) had their infiltrating lymphocytes characterized by immunohistochemical analyses. Both LT and HT showed similar immunostaining patterns for CD4, CD8, CD68, thus supporting a common pathophysiology mechanism and indicating that LT and HT should be considered different presentations of a same condition, that is, autoimmune thyroiditis. Moreover, apoptosis markers strongly evidenced that apoptosis was present in all studied cases. Our results demonstrated an impressive increase in the prevalence of thyroiditis during recent years and our data support that the terminology of autoimmune thyroiditis should be used to designate both LT and HT. This classification would facilitate comparison of prevalence data from different series and studies.

  18. The high prevalence of undiagnosed prostate cancer at autopsy: implications for epidemiology and treatment of prostate cancer in the Prostate-specific Antigen-era. (United States)

    Jahn, Jaquelyn L; Giovannucci, Edward L; Stampfer, Meir J


    Widespread prostate-specific antigen (PSA) screening detects many cancers that would have otherwise gone undiagnosed. To estimate the prevalence of unsuspected prostate cancer, we reviewed 19 studies of prostate cancer discovered at autopsy among 6,024 men. Among men aged 70-79, tumor was found in 36% of Caucasians and 51% of African-Americans. This enormous prevalence, coupled with the high sensitivity of PSA screening, has led to the marked increase in the apparent incidence of prostate cancer. The impact of PSA screening on clinical practice is well-recognized, but its effect on epidemiologic research is less appreciated. Before screening, a larger proportion of incident prostate cancers had lethal potential and were diagnosed at advanced stage. However, in the PSA era, overall incident prostate cancer mainly is indolent disease, and often reflects the propensity to be screened and biopsied. Studies must therefore focus on cancers with lethal potential, and include long follow-up to accommodate the lead time induced by screening. Moreover, risk factor patterns differ markedly for potentially lethal and indolent disease, suggesting separate etiologies and distinct disease entities. Studies of total incident or indolent prostate cancer are of limited clinical utility, and the main focus of research should be on prostate cancers of lethal potential.

  19. Suicidal single gunshot injury to the head: differences in site of entrance wound and direction of the bullet path between right- and left-handed--an autopsy study. (United States)

    Nikolić, Slobodan; Zivković, Vladimir; Babić, Dragan; Juković, Fehim


    The aim of this study was to determine the differences in the anatomical site of a gunshot entrance wound and the direction of the bullet path between right- and left-handed subjects who committed a suicide by a single gunshot injury to the head. The retrospective autopsy study was performed for a 10-year period, and it included selected cases of single suicidal gunshot head injury, committed by handguns. We considered only contact or near-contact wounds. The sample included 479 deceased, with average age 47.1 ± 19.1 years (range, 12-89 years): 432 males and 47 females, with 317 right-handed, 25 left-handed, and 137 subjects with unknown dominant hand. In our observed sample, most cases involved the right temple as the site of entrance gunshot wound (about 67%), followed by the mouth (16%), forehead (7%), left temple (6%), submental (2%), and parietal region (1%). The left temple, right temple, and forehead were the sites of the gunshot entrance wounds, which were the best predictors of the handedness of the deceased (Spearman ρ = 0.149, P = 0.006). Our study showed that the direction of the bullet intracranial path in cases of suicide was even a more potent predictor of the handedness of the deceased (Spearman ρ = 0.263, P = 0.000; Wald = 149.503, P = 0.000).

  20. Argyrophilic grain disease mimicking temporal Pick's disease: a clinical, radiological, and pathological study of an autopsy case with a clinical course of 15 years. (United States)

    Tsuchiya, K; Mitani, K; Arai, T; Yamada, S; Komiya, T; Esaki, Y; Haga, C; Yamanouchi, H; Ikeda, K


    This report concerns an autopsy case of argyrophilic grain disease (AGD) mimicking temporal Pick's disease. The patient was a Japanese woman without hereditary burden who was 89 years old at the time of death. She developed memory impairment and began wandering at the age of 74, followed by prominent character changes about 6 years after disease onset. A neurological examination 5 months before her death revealed poor rapport, unconcern, severe dementia, and double incontinence, without aphasia or muscle rigidity. Serial neuroradiological examination revealed progressive enlargement of the bilateral inferior horns of the lateral ventricle, reflecting progressive atrophy of the medial temporal lobes. Macroscopically, neuropathological examination showed circumscribed atrophy of the bilateral amygdalae, hippocampi, parahippocampal gyri, and lateral occipitotemporal gyri. Histologically, there was neuronal loss in the areas mentioned above, the caudate nucleus, putamen, thalamus, substantia nigra, and locus ceruleus, with ballooned neurons in the cerebral cortex and amygdala. Numerous argyrophilic grains with coiled bodies were present not only in the limbic system, but also in the affected cerebrum. Rare neurofibrillary changes were present in the limbic areas, consistent with Braak stage II, with no senile plaques. Based on these findings and a review of the literature, we note that AGD is clinicopathologically similar not only to mesolimbocortical dementia, but also to atypical senile dementia of Alzheimer type. This report may contribute to the elucidation of the clinicopathological hallmarks of AGD.

  1. Incidence and Size of Patent Foramen Ovale During the First 10 Decades of Life: An Autopsy Study of 965 Normal Hearts (United States)

    Hagen, Philip T.; Scholz, David G.; Edwards, William D.


    The incidence and size of the patent foramen ovale were studied in 965 autopsy specimens of human hearts, which were from subjects who were evenly distributed by sex and age. Neither incidence nor size of the defect was significantly different between male and female subjects. The overall incidence was 27.3%, but it progressively declined with increasing age from 34.3% during the first three decades of life to 25.4% during the 4th through 8th decades and to 20.2% during the 9th and 10th decades. Among the 263 specimens that exhibited patency in our study, the foramen ovale ranged from 1 to 19 mm in maximal potential diameter (mean, 4.9 mm). In 98% of these cases, the foramen ovale was 1 to 10 mm in diameter. The size tended to increase with increasing age, from a mean of 3.4 mm in the first decade to 5.8 mm in the 10th decade of life.

  2. Phenotypic patterns of MELAS/LS overlap syndrome associated with m.13513G>A mutation, and neuropathological findings in one autopsy case. (United States)

    Wang, Zhaoxia; Qi, Xiao Kun; Yao, Sheng; Chen, Bin; Luan, Xinghua; Zhang, Wei; Han, Manfu; Yuan, Yun


    The 13513G>A mutation in the ND5 gene of mitochondrial DNA (mtDNA) is usually associated with mitochondrial encephalomyopathy with lactate acidosis and stroke-like episodes (MELAS), or Leigh syndrome (LS). In this study, we describe three young Chinese patients with MELAS/LS overlap syndrome who carried the m.13513G>A mutation. Clinical and MRI features were characteristic of both MELAS and LS. Interestingly, the clinical presentation of this overlap syndrome could be variable depending on the degree of relative contribution of MELAS and LS, that is, MELAS as the initial presenting syndrome, LS as the predominant syndrome, or both MELAS and LS appearing at the same time. The final brain MRI showed findings characteristic of both MELAS and LS, with asymmetrical lesions in the cortex and subcortical white matter of the occipital, temporal, and frontal lobes (MELAS), and bilateral and symmetrical lesions in the basal ganglia and brainstem (LS). Brain autopsy in one case revealed infarct-like lesions in the cerebral cortex, basal ganglia and brainstem, providing further insight into the distribution of the pathological lesions in MELAS/LS overlap syndrome. This is the first report of the brain pathological changes in a patient with m.13513G>A mutation. The spatial distribution of infarct-like lesions in the brain could explain the symptoms in MELAS/LS overlap syndrome.

  3. Instantaneous death due to transorbital reverse penetration of a screw in an accidental fall: unusual autopsy case report and review of the literature. (United States)

    Gioia, Sara; Bacci, Mauro; Lancia, Massimo; Carlini, Luigi; Suadoni, Fabio


    We present a peculiar autopsy case of a transorbital penetrating head injury, in a male worker, after an accidental fall onto a screw not completely stuck into a wooden board. A 13-cm screw entered the cranium 9.5 cm deep, penetrating with the flat end, a condition defined in literature as "reverse penetration." The death was instantaneous and caused by a neurogenic shock due to injuries to the brain stem and the right cerebellar hemisphere. These injuries, enabled by the length of the screw, are generally described in literature as due to nontransorbital penetrations, frequently associated with posterior entry and a large intracranial injury. The ocular globe has been, furthermore, perfectly preserved thanks to its mobility in the orbit. Even the dynamic of the incident is peculiar because of the stationary nature of the penetrating object, which the victim actively fell on by accident. To the best of our knowledge, the matter is therefore a very peculiar mortal case of transorbital intracranial penetration, whose verified injuries and dynamics are absolutely atypical. The case is now under discussion, and a review of pertinent literature is performed.

  4. Is motor neuron disease-inclusion dementia a forme fruste of amyotrophic lateral sclerosis with dementia? An autopsy case further supporting the disease concept. (United States)

    Toyoshima, Yasuko; Tan, Chun-Feng; Kozakai, Tetsuro; Tanaka, Masaharu; Takahashi, Hitoshi


    We report the autopsy findings of a 62-year-old man who exhibited progressive FTD 10 years before the appearance of muscle weakness and wasting, and who died approximately 11 years after onset of the symptoms. Degeneration and atrophy of the frontal and temporal lobes, which contained ubiquitin-positive neuronal inclusions and dystrophic neurites, were evident. Circumscribed degeneration affecting the hippocampal CA1-subiculum border zone was also a feature. Moreover, degeneration was present in both the upper and lower motor neuron systems, the latter being more severely affected. A few lower motor neurons were found to contain the cytoplasmic inclusions characteristic of ALS (i.e. Bunina bodies and ubiquitin-positive skeins). Also of interest was the presence of pallidonigroluysian atrophy, which appeared to be responsible for the chorea-like involuntary movements that developed in this patient approximately 2 months before death. The clinical and pathological features of our patient further support the idea that motor neuron disease-inclusion dementia (MND-ID), which has been classified as a pathological subgroup of FTD, is a forme fruste of ALS with dementia. In other words, if patients with MND-ID live long enough, they may develop ALS.

  5. "Whenever they cry, I cry with them": Reciprocal relationships and the role of ethics in a verbal autopsy study in Papua New Guinea. (United States)

    Gouda, H N; Kelly-Hanku, A; Wilson, L; Maraga, S; Riley, I D


    Verbal autopsy (VA) methods usually involve an interview with a recently bereaved individual to ascertain the most probable cause of death when a person dies outside of a hospital and/or did not receive a reliable death certificate. A number of concerns have arisen around the ethical and social implications of the use of these methods. In this paper we examine these concerns, looking specifically at the cultural factors surrounding death and mourning in Papua New Guinea, and the potential for VA interviews to cause emotional distress in both the bereaved respondent and the VA fieldworker. Thirty one semi-structured interviews with VA respondents, the VA team and community relations officers as well as observations in the field and team discussions were conducted between June 2013 and August 2014. While our findings reveal that VA participants were often moved to cry and feel sad, they also expressed a number of ways they benefited from the process, and indeed welcomed longer transactions with the VA interviewers. Significantly, this paper highlights the ways in which VA interviewers, who have hitherto been largely neglected in the literature, navigate transactions with the participants and make everyday decisions about their relationships with them in order to ensure that they and VA interviews are accepted by the community. The role of the VA fieldworker should be more carefully considered, as should the implications for training and institutional support that follow.

    Full Text Available INTRODUÇÃO: O declínio no número de autópsias em hospitais e instituições universitárias é evento amplamente reportado, inicialmente em países do primeiro mundo e posteriormente em muitos países em desenvolvimento, como o Brasil. As causas para essa tendência são múltiplas e complexas, incluindo aspectos religiosos, familiares e médicos. Entre estes últimos, salientam-se razões diagnósticas, caracterizadas pelo significativo avanço tecnológico na imagenologia, com a suposição de que todos os diagnósticos agora podem ser feitos em vida, e a crescente ansiedade de processos judiciais contra médicos por má prática. OBJETIVO: Demonstrar o decréscimo vertiginoso e drástico do número de autópsias em um hospital universitário no Brasil. MATERIAL E MÉTODO: Avaliou-se o número de registros nos livros de autópsias consecutivas realizadas no Departamento de Patologia do Hospital Universitário Antonio Pedro da Universidade Federal Fluminense (HUAP/UFF, Niterói, Rio de Janeiro, criando um banco dados em tabela do programa Microsoft Excel. RESULTADOS: Durante os anos 1966 a 2009, foram realizadas 23.813 necrópsias, sendo 12.702 de adultos e 11.111 de fetos. Entre os anos 1966 e 1998, foram realizadas mais necrópsias, no total de 23.321, sendo 12.482 de adultos e 10.839 de fetos. Já entre os anos 1999 e 2009, foi observado o declínio acentuado e drástico das mesmas, totalizando apenas 492 necrópsias, sendo 220 de adultos e 272 de fetos. CONCLUSÃO: Acreditamos que a principal causa para esse declínio é a pouca informação da população, que desconhece que o saber é fruto de estudo, pesquisa, prática e aprimoramento.INTRODUCTION: The decline in the number of autopsies at hospitals and university hospitals has been widely reported, initially in developed countries and afterwards in several developing countries including Brazil.

    Maliti Deodatus V


    Full Text Available Abstract Background Verbal autopsy (VA is a widely used tool to assign probable cause of death in areas with inadequate vital registration systems. Its uses in priority setting and health planning are well documented in sub-Saharan Africa (SSA and Asia. However, there is a lack of data related to VA processing and completion rates in assigning causes of death in a community. There is also a lack of data on factors associated with undetermined causes of death documented in SSA. There is a need for such information for understanding the gaps in VA processing and better estimating disease burden. Objective The study's intent was to determine the completion rate of VA and factors associated with assigning undetermined causes of death in rural Tanzania. Methods A database of deaths reported from the Ifakara Health and Demographic Surveillance System from 2002 to 2007 was used. Completion rates were determined at the following stages of processing: 1 death identified; 2 VA interviews conducted; 3 VA forms submitted to physicians; 4 coding and assigning of cause of death. Logistic regression was used to determine factors associated with deaths coded as "undetermined." Results The completion rate of VA after identification of death and the VA interview ranged from 83% in 2002 and 89% in 2007. Ninety-four percent of deaths submitted to physicians were assigned a specific cause, with 31% of the causes coded as undetermined. Neonates and child deaths that occurred outside health facilities were associated with a high rate of undetermined classification (33%, odds ratio [OR] = 1.33, 95% confidence interval [CI] (1.05, 1.67, p = 0.016. Respondents reporting high education levels were less likely to be associated with deaths that were classified as undetermined (24%, OR = 0.76, 95% CI (0.60, -0.96, p = 0.023. Being a child of the deceased compared to a partner (husband or wife was more likely to be associated with undetermined cause of death classification

    Fatal mass casualties by high velocity bullets (HVBs) are rare events in peaceful countries. This study presents 27 forensic autopsy cases with 32 shots fired by 5.56×45mm. HVB (M-16 rifle bullets) during the dispersing the mass rally in Bangkok Thailand, May 2010. It was found that twenty-three (71.88%) typical entrance HVB wounds had round sizes less than the bullet diameters. Most entrance wounds had microtears but no collar abrasion since a HVB has a small streamlined spitzer tip and full metal jacket. For exit wounds, there were various sizes and shapes depending on which section of wound ballistics presented when the bullet exited the body. If a bullet exited in the section of temporally cavity formation, there would be a large size exit wound in accordance with the degree of bullet yaw. This is different from civilian bullets whereby the shape looks like a cylindrical round nose and at low velocity that causes entrance wounds with a similar size to the bullet diameter and is usually round or oval shape with collar abrasion. The temporary cavity is not as large as in a HVB so exit wounds are not quite as large and present a ragged border compared to a HVB. We also reported 9 out of 32 shots (28.13%) of atypical entrance wounds that had various characteristics depending on site of injury and destabilization of bullets. These findings may be helpful to forensic pathologists and to give physicians, who need to diagnose HVB wounds, more confidence.

  11. Concentrations of alprazolam in blood from impaired drivers and forensic autopsies were not much different but showed a high prevalence of co-ingested illicit drugs. (United States)

    Jones, Alan Wayne; Holmgren, Anita


    Alprazolam is a benzodiazepine anxiolytic widely prescribed for treatment of panic-disorder and social phobias, although this medication is also subject to abuse. In this paper, the concentrations of alprazolam in venous blood samples from impaired drivers were compared with femoral blood samples from forensic autopsies classified as intoxication or other causes of death (e.g. natural, trauma). After liquid-liquid extraction (n-butyl acetate) alprazolam was determined in blood by capillary gas chromatography with a nitrogen-phosphorous detector. The mean (median) and range of alprazolam concentrations in blood from impaired drivers (n = 773) were 0.08 mg/L (0.05 mg/L) and 0.02-3.9 mg/L, respectively. Many traffic offenders had co-ingested ethanol (13%), amphetamine (46%), cannabis (32%), or heroin (14%), as well as other drugs. In deaths attributed to drug intoxication, the mean (median) and range of alprazolam concentrations in blood (n = 438) were 0.10 mg/L (0.06 mg/L) and 0.02-1.6 mg/L, respectively, which were not much different from other causes of death (n = 278); 0.08 mg/L (0.05 mg/L) and 0.02-0.9 mg/L. Median concentrations of alprazolam in blood from living and deceased persons did not seem to depend on the number of co-ingested substances. The result of this pharmacoepidemiological study suggests that alprazolam is a fairly innocent drug when used as monotherapy, but toxicity problems arise when co-ingested with illicit drugs and/or psychoactive medication.

  12. Demographic, clinical and pathological features of sudden deaths due to myocarditis: Results from a state-wide population-based autopsy study. (United States)

    Li, Liliang; Zhang, Yang; Burke, Allen; Xue, Aimin; Zhao, Ziqin; Fowler, David; Shen, Yiwen; Li, Ling


    Causes of sudden cardiac deaths have been widely reported with limited data focused specifically on myocarditis. A retrospective review of cases from the Office of the Chief Medical Examiner (OCME), State of Maryland yielded a total of 103 sudden unexpected deaths (SUDs) due to myocarditis (0.17% of all SUDs and 0.70% of autopsied SUDs) from 2005 through 2014. Most deaths occurred in patients <30 years of age with a male:female ratio 1.3:1. Of the 103 cases, 45 (43.7%) patients were witnessed collapsed. Four deaths occurred during exertion, such as exercising at the gym or performing heavy physical work, and 2 deaths were associated with emotional stress. The common cardiac macroscopic findings included ventricular dilatation (39.8%), mild coronary stenosis (17.5%), mottled myocardial appearance (15.5%), and myocardial fibrosis (10.7%). The histological classification of myocarditis was based on the predominant type of inflammatory cell infiltration. In our study group, lymphocytic myocarditis was most common, accounting for 56 cases (54.4%), followed by neutrophilic (32 cases, 31.7%), eosinophilic (13 cases, 12.6%) and giant cell type (2 cases, 1.9%). Microscopic examination revealed myocyte necrosis in 69 cases (67.0%) and interstitial or perivascular fibrosis in 48 cases (46.6%). The percentage of myocyte necrosis was 75.0% (42/58 cases) in lymphocytic, 65.6% (21/31 cases) in neutrophilic, 30.8% (4/13 cases) in eosinophilic, and 100% (2/2 cases) in giant cell myocarditis. Determination of myocarditis as cause of death continues to present a major challenge to forensic pathologists, because histopathologic findings can be subtle and the diagnosis of myocarditis remains difficult.

  13. Homovanillic acid and 5-hydroxyindole acetic acid as biomarkers for dementia with Lewy bodies and coincident Alzheimer’s disease: An autopsy-confirmed study (United States)

    Takao, Masaki; Hatsuta, Hiroyuki; Nishina, Yasushi; Komiya, Tadashi; Sengoku, Renpei; Nakano, Yuta; Uchino, Akiko; Sumikura, Hiroyuki; Saito, Yuko; Kanemaru, Kazutomi; Murayama, Shigeo


    Dementia with Lewy bodies (DLB) and Alzheimer’s disease (AD) are the two most common causes of dementia. Both pathologies often coexist, and AD patients with concomitant neocortical LB pathology (referred to as the Lewy body variant of AD) generally show faster cognitive decline and accelerated mortality relative to patients with pure AD. Thus, discriminating among patients with DLB, AD, and coincident DLB and AD is important in clinical practice. We examined levels of homovanillic acid (HVA), 5-hydroxyindole acetic acid (5-HIAA), tau, phosphorylated tau (p-tau), and beta-amyloid (Aβ) 1–42 in cerebrospinal fluid (CSF) to evaluate their viability as biomarkers to discriminate among different forms of dementia. We obtained a total of 3498 CSF samples from patients admitted to our hospital during the period from 1996 to 2015. Of these patients, we were able to carry out a brain autopsy in 94 cases. Finally, 78 neuropathologically diagnosed cases (10 AD, six DLB, five DLB with AD, five controls without neurological diseases, and 52 cases with other neurological diseases) were studied. CSF levels of HVA and 5-HIAA were consistently decreased in pathologically advanced Lewy body disorder (LBD; Braak LB stages >3) compared with pathologically incipient LBD (Braak LB stages <2). These results suggest that if an individual has LB pathology in the central nervous system, CSF levels of HVA and 5-HIAA may decrease after the onset of clinical symptoms. In addition, CSF levels of HVA and 5-HIAA decreased with LB pathology, and were especially low in cases of DLB and DLB with AD. Furthermore, the combination of HVA, 5-HIAA, and brain specific proteins t-tau, p-tau, and Aβ 1–42 in CSF were useful for discriminating among DLB, DLB with AD, and AD with high diagnostic accuracy.

    Full Text Available Shanghai is the most developed city in China and has a soaring population. This study uses forensic epidemiology to determine the relationship between unnatural deaths and the development in Shanghai, based on recently released forensic autopsy cases from the 2000s at the Shanghai Public Security Bureau (SPSB. There were 5425 accidental deaths, 2696 homicides, 429 suicides, 186 natural deaths, and 1399 deaths of undetermined cause. There was a male-to-female ratio of 2.02:1, and the average age was 40.9±18.7 years. Traffic accidents (84.2% were the number one cause of accidental deaths, which decreased during the study period. Sharp force injury (50.6% was the leading cause of homicides, different from Western countries, where firearms are the leading cause. Hanging (24.5% was the leading cause of suicides, whereas drug and chemical intoxication was the leading cause in the previous decade; pesticide ingestion decreased in the 2000s. In addition to traffic accidents, manual strangulation was the leading cause of death in childhood fatalities. Children under age 2 were vulnerable to homicides. In the 2000s, there were a large number of drug overdoses, and illegal medical practices and subway-related deaths first appeared in Shanghai. A new type of terrorist attack that involved injecting people with syringes in public places was reflected in the SPSB archives. The forensic epidemiology and changes in unnatural deaths in this decade reflected their relationship with the law, policy and changes in Shanghai. Illegal medical practices, subway-related deaths and terrorist attacks were closely related to the development in Shanghai. Identifying the risks of unnatural deaths will improve public health.

  15. Association of the formiminotransferase N-terminal sub-domain containing gene and thrombospondin, type 1, domain-containing 7A gene with the prevalence of vertebral fracture in 2427 consecutive autopsy cases. (United States)

    Zhou, Heying; Mori, Seijiro; Kou, Ikuyo; Fuku, Noriyuki; Naka Mieno, Makiko; Honma, Naoko; Arai, Tomio; Sawabe, Motoji; Tanaka, Masashi; Ikegawa, Shiro; Ito, Hideki


    We previously reported 2 osteoporosis-susceptibility genes--formiminotransferase N-terminal sub-domain containing gene (FONG) and thrombospondin, type 1, domain-containing 7A (THSD7A)--in which we identified two common single-nucleotide polymorphisms, rs7605378 (FONG) and rs12673692 (THSD7A). The former was associated with a predisposition to osteoporosis and the latter with bone mineral density. To further elucidate the importance of these polymorphisms in the pathogenesis of osteoporosis, we examined their association with the incidence of vertebral fracture. DNA extracted from the renal cortex of 2427 consecutive Japanese autopsies (1331 men, mean age: 79 years; 1096 women, mean age: 82 years) were examined in this study. The presence or absence of vertebral fracture during each subject's lifetime was determined by a thorough examination of the clinical records, as well as autopsy reports. After adjustments for sex and age at autopsy, logistic regression analysis revealed that homozygotes for the risk alleles of rs7605378 (A-allele) or rs12673629 (A-allele) possess an increased risk of vertebral fracture. The subjects simultaneously homozygous for both the risk alleles of rs7605378 (AA genotype) and rs12673629 (AA genotype) showed significantly higher risk of vertebral fracture (odds ratio 2.401, 95% confidence interval 1.305-4.416, P = 0.0048) than those who had at least one non-risk allele of either rs7605378 (AC/CC genotypes) or rs12673629 (AG/GG genotypes). The results suggest that Japanese subjects homozygous for the risk alleles of rs7605378 and rs12673629 have a higher risk of vertebral fracture.

    Reyes, H; Tomé, P; Guiscafré, H; Martínez, H; Romero, G; Portillo, E; Rodríguez, R; Gutiérrez, G


    The study focuses on children between 72 hours and five years of age who died of acute respiratory infection (ARI) or acute diarrhea (AD) in the State of Tlaxcala. Peer Review Mortality Committee of the State contributed with the staff to the deaths analysis. Cases were included only when diagnosis was confirmed by verbal autopsy (VA). One hundred and thirty two cases were included (98 corresponding to ARI deaths and 34 to AD). The process related to medical care-seeking behaviors and prescribing practices by private and non-private physicians was analyzed through the VA. During the study period, 60% of children with ARI and 58.9% of children with AD died at home. More than 80% of these children had received medical care within three days preceding their death, and 50% of them had been seen by a physician within 12 hours prior to their death. Most of these visits were to a private doctor (71% for ARI and 86% for AD). Forty seven percent of treatments prescribed for ARI were judged to be wrong, either because of a bad choice of antibiotic or because the physician did not prescribe an antibiotic when the patient required it. Similarly, 65% of treatments for AD were considered erroneous, either due to the use of an antibiotic which was not justified or due to the lack of oral rehydration therapy when it was needed. Additionally, late referral to a hospital was considered as having direct influence at the death in half of the consultation. Families were too late in demanding medical care or demanded no care at all in 21.9% of cases of ARI and in 6.1% of cases of AD. We have found the VA to be useful in identifying problems related to the process of health-seeking behaviors and medical care. Our results suggest interventions that may lower the high mortality rates in Tlaxcala, such as training workshops directed to institutional and private physicians, and the implementation of top-of-line treatment centers where high-risk patients can be referred and also the health

    C. King


    Full Text Available Abstract Background Verbal autopsy (VA, the process of interviewing a deceased’s family or caregiver about signs and symptoms leading up to death, employs tools that ask a series of closed questions and can include an open narrative where respondents give an unprompted account of events preceding death. The extent to which an individual interviewer, who generally does not interpret the data, affects the quality of this data, and therefore the assigned cause of death, is poorly documented. We aimed to examine inter-interviewer reliability of open narrative and closed question data gathered during VA interviews. Methods During the introduction of VA data collection, as part of a larger study in Mchinji district, Malawi, we conducted partner interviews whereby two interviewers independently recorded open narrative and closed questions during the same interview. Closed questions were collected using a smartphone application (mobile-InterVA and open narratives using pen and paper. We used mixed methods of analysis to evaluate the differences between recorded responses to open narratives and closed questions, causes of death assigned, and additional information gathered by open narrative. Results Eighteen partner interviews were conducted, with complete data for 11 pairs. Comparing closed questions between interviewers, the median number of differences was 1 (IQR: 0.5–3.5 of an average 65 answered; mean inter-interviewer concordance was 92 % (IQR: 92–99 %. Discrepancies in open narratives were summarized in five categories: demographics, history and care-seeking, diagnoses and symptoms, treatment and cultural. Most discrepancies were seen in the reporting of diagnoses and symptoms (e.g., malaria diagnosis; only one pair demonstrated no clear differences. The average number of clinical symptoms reported was 9 in open narratives and 20 in the closed questions. Open narratives contained additional information on health seeking and social issues

    Nurul Alam


    Full Text Available Objective: Population-based information on causes of death (CoD by age, sex, and area is critical for countries with limited resources to identify and address key public health issues. This study analysed the demographic surveillance and verbal autopsy (VA data to estimate age- and sex-specific mortality rates and cause-specific mortality fractions in two well-defined rural populations within the demographic surveillance system in Abhoynagar and Mirsarai subdistricts, located in different climatic zones. Design: During 2004–2010, the sample demographic surveillance system registered 1,384 deaths in Abhoynagar and 1,847 deaths in Mirsarai. Trained interviewers interviewed the main caretaker of the deceased with standard VA questionnaires to record signs and symptoms of diseases or conditions that led to death and health care experiences before death. The computer-automated InterVA-4 method was used to analyse VAs to determine probable CoD. Results: Age- and sex-specific death rates revealed a higher neonatal mortality rate in Abhoynagar than Mirsarai, and death rates and sex ratios of male to female death rates were higher in the ages after infancy. Communicable diseases (CDs accounted for 16.7% of all deaths in Abhoynagar and 21.2% in Mirsarai – the difference was due mostly to more deaths from acute respiratory infections, pneumonia, and tuberculosis in Mirsarai. Non-communicable diseases (NCDs accounted for 56.2 and 55.3% of deaths in each subdistrict, respectively, with leading causes being stroke (16.5–19.3%, neoplasms (13.2% each, cardiac diseases (8.9–11.6%, chronic obstructive pulmonary diseases (5.1–6.3%, diseases of the digestive system (3.1–4.1%, and diabetes (2.8–3.5%, together accounting for 49.2–51.2% points of the NCD deaths in the two subdistricts. Injury and other external causes accounted for another 7.5–7.7% deaths, with self-harm being higher among females in Abhoynagar. Conclusions: The computer

    Full Text Available Background Reducing preventable medical causes of neonatal death for faster progress toward the MGD4 will require Cameroon to adequately address the social factors contributing to these deaths. The objective of this paper is to explore the social, behavioral and health systems determinants of newborn death in Doume, Nguelemendouka and Abong–Mbang health districts, in Eastern Region of Cameroon, from 2007–2010. Methods Data come from the 2012 Verbal/Social Autopsy (VASA study, which aimed to determine the biological causes and social, behavioral and health systems determinants of under–five deaths in Doume, Nguelemendouka and Abong–Mbang health districts in Eastern Region of Cameroon. The analysis of the data was guided by the review of the coverage of key interventions along the continuum of normal maternal and newborn care and by the description of breakdowns in the care provided for severe neonatal illnesses within the Pathway to Survival conceptual framework. Results One hundred sixty–four newborn deaths were confirmed from the VASA survey. The majority of the deceased newborns were living in households with poor socio–economic conditions. Most (60–80% neonates were born to mothers who had one or more pregnancy or labor and delivery complications. Only 23% of the de ceased newborns benefited from hygienic cord care after birth. Half received appropriate thermal care and only 6% were breastfed within one hour after birth. Sixty percent of the deaths occurred during the first day of life. Fifty–five percent of the babies were born at home. More than half of the deaths (57% occurred at home. Of the 64 neonates born at a health facility, about 63% died in the health facility without leaving. Careseeking was delayed for several neonates who became sick after the first week of life and whose illnesses were less serious at the onset until they became more severely ill.

    The relationship between late-life body mass index (BMI) and Alzheimer's disease (AD) is poorly understood due to the lack of research in samples with autopsy-confirmed AD neuropathology (ADNP). The role of cerebrovascular disease (CVD) in the interplay between late-life BMI and ADNP is unclear. We conducted a retrospective longitudinal investigation and used joint modeling of linear mixed effects to investigate causal relationships among repeated antemortem BMI measurements, CVD (quantified neuropathologically), and ADNP in an autopsy sample of subjects across the AD clinical continuum. The sample included 1,421 subjects from the National Alzheimer's Coordinating Center's Uniform Data Set and Neuropathology Data Set with diagnoses of normal cognition (NC; n = 234), mild cognitive impairment (MCI; n = 201), or AD dementia (n = 986). ADNP was defined as moderate to frequent neuritic plaques and Braak stageIII-VI. Ischemic Injury Scale (IIS) operationalized CVD. Joint modeling examined relationships among BMI, IIS, and ADNP in the overall sample and stratified by initial visit Clinical Dementia Rating score. Subject-specific random intercept for BMI was the predictor for ADNP due to minimal BMI change (p = 0.3028). Analyses controlling for demographic variables and APOE ɛ4 showed lower late-life BMI predicted increased odds of ADNP in the overall sample (p < 0.001), and in subjects with CDR of 0 (p = 0.0021) and 0.5 (p = 0.0012), but not ≥1.0 (p = 0.2012). Although higher IIS predicted greater odds of ADNP (p < 0.0001), BMI did not predict IIS (p = 0.2814). The current findings confirm lower late-life BMI confers increased odds for ADNP. Lower late-life BMI may be a preclinical indicator of underlying ADNP.

O estudo parte de 26 laudos periciais de homens e mulheres que cometeram suicídios no centro, na zona norte e na zona sul da cidade. As famílias desses idosos foram contatadas por carta e telefone e depois, pessoalmente. Foram oito autópsias psicológicas, por meio das quais foram coletados dados de identificação, genograma da família e uma entrevista que reconstituiu o modo de vida e as razões da violência autoinfligida. Os entrevistados foram familiares, amigos e conhecidos das vítimas. Os suicídios estão associados a depressão, a enfermidades físicas e mentais graves e a fatores socioculturais como decadência profissional e socioeconômica. Esses eventos ocorreram com e sem apoio familiar, com e sem acompanhamento médico. A fragilização cumulativa de recursos pessoais e sociais no ciclo vital revela que o risco do suicídio em idosos exige cuidados permanentes de saúde pública.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.

    Background The minimally invasive autopsy (MIA) is being investigated as an alternative to complete diagnostic autopsies for cause of death (CoD) investigation. Before potential implementation of the MIA in settings where post-mortem procedures are unusual, a thorough assessment of its feasibility and acceptability is essential. Methods and Findings We conducted a socio-behavioural study at the community level to understand local attitudes and perceptions related to death and the hypothetical feasibility and acceptability of conducting MIAs in six distinct settings in Gabon, Kenya, Mali, Mozambique, and Pakistan. A total of 504 interviews (135 key informants, 175 health providers [including formal health professionals and traditional or informal health providers], and 194 relatives of deceased people) were conducted. The constructs “willingness to know the CoD” and “hypothetical acceptability of MIAs” were quantified and analysed using the framework analysis approach to compare the occurrence of themes related to acceptability across participants. Overall, 75% (379/504) of the participants would be willing to know the CoD of a relative. The overall hypothetical acceptability of MIA on a relative was 73% (366/504). The idea of the MIA was acceptable because of its perceived simplicity and rapidity and particularly for not “mutilating” the body. Further, MIAs were believed to help prevent infectious diseases, address hereditary diseases, clarify the CoD, and avoid witchcraft accusations and conflicts within families. The main concerns regarding the procedure included the potential breach of confidentiality on the CoD, the misperception of organ removal, and the incompatibility with some religious beliefs. Formal health professionals were concerned about possible contradictions between the MIA findings and the clinical pre-mortem diagnoses. Acceptability of the MIA was equally high among Christian and Islamic communities. However, in the two predominantly

    Directory of Open Access Journals (Sweden)

    Stray-Pedersen Arne


    Full Text Available The present paper reports a 7 year old girl’s death by hanging. The forensic investigation disclosed death most likely to be self-inflicted, either an act of suicide, subsidiary a case of accidental asphyxia from a child’s play. A review of forensic autopsy records from southeast Norway during the years 1984-2012 was performed. Totally 116 deaths among children and adolescents < 18 years of age were classified as either suicide or as “undetermined - suicide likely” subsequent to post-mortem examination. The most common suicidal methods were hanging (46%, the use of firearms (24%, jumping in front of a train (11% and drug intake / intoxication (8%. Though rarely observed in children < 12 years of age, suicide is a common cause of sudden death in adolescents, and there is evidence that the extent of the problem is unceasing. The paper highlights the value of forensic medical examination and crime scene reenactment in the evaluation of the manner of death in obscure cases.

Histological analysis showed high prevalence of type III atherosclerotic lesions in both DA (69% and CA (39% arteries, while severe type IV and V lesions were observed in 14% (DA and 33% (CA. Allele frequencies and genotype distributions were determined. Among the polymorphisms studied, IFN-γ and IL-10 (−1082 A/G were related to atherosclerosis severity in DA artery. No association between genotypes and lesion severity was found in CA. In conclusion, we observed that the high prevalence of early atherosclerosis in young adults is associated with IFN-γ (p < 0.001 and IL-10 (p = 0.013 genotypes. This association is blood vessel dependent. Our findings suggest that the vascular system presents site specialization, and specific genetic variations may provide future biomarkers for early disease identification.

    Injuries such as bite marks or boot prints can leave distinct patterns on the body's surface and can be used for 3D reconstructions. Although various systems for 3D surface imaging have been introduced in the forensic field, most techniques are both cost-intensive and time-consuming. In this article, we present the VirtoScan, a mobile, multi-camera rig based on close-range photogrammetry. The system can be integrated into automated PMCT scanning procedures or used manually together with lifting carts, autopsy tables and examination couch. The VirtoScan is based on a moveable frame that carries 7 digital single-lens reflex cameras. A remote control is attached to each camera and allows the simultaneous triggering of the shutter release of all cameras. Data acquisition in combination with the PMCT scanning procedures took 3:34 min for the 3D surface documentation of one side of the body compared to 20:20 min of acquisition time when using our in-house standard. A surface model comparison between the high resolution output from our in-house standard and a high resolution model from the multi-camera rig showed a mean surface deviation of 0.36 mm for the whole body scan and 0.13 mm for a second comparison of a detailed section of the scan. The use of the multi-camera rig reduces the acquisition time for whole-body surface documentations in medico-legal examinations and provides a low-cost 3D surface scanning alternative for forensic investigations.

    Full Text Available Background/Aim. The Glu298Asp variant in exon 7 and T-786C mutation in the 5'-flanking region of the endothelial nitric oxide synthase (eNOS gene, paraoxonase I gene (PON1, and α2β- adrenergic receptor gene (α2β-AR have been reported to be genetic risk factors for coronary heart disease (CHD. The aim of this study was to investigate the effects of these four genetic polymorphisms on the probability of death due to CHD, using data obtained from medico-legal autopsies. Methods. Blood samples from three groups: healthy controls, dead cases with CHD and without CHD (the latter as a control for dead cases were used. After DNA extraction, genotyping was performed by polymerase chain reaction − restriction fragment length polymorphism (PCR-RFLP test. Results. The frequency of the T allele in Glu298Asp variant in the dead cases with CHD was significantly higher than that in the healthy control (p < 0.001, OR = 4.47 and that in the dead cases without CHD (p < 0.001, OR = 7.62. The gene frequency of PON1 was significantly different (p = 0.007 between dead cases with and without CHD, and was also significantly different (p = 0.025 between the healthy control and dead cases without CHD. The gene frequency of PON1 was not significantly different (p = 0.401 between the healthy controls and dead cases with CHD. Hence this gene was not associated with death due to CHD. The other polymorphisms (T- 786C mutation, α2β-AR also showed no effect on death due to CHD. Conclusion. The polymorphism of Glu298Asp eNOS gene in dead cases may be useful for determining the cause of death in CHD cases in the Japanese population.

  20. Metallographic autopsies of full-scale ITER prototype cable-in-conduit conductors after full cyclic testing in SULTAN: III. The importance of strand surface roughness in long twist pitch conductors (United States)

    Sanabria, Charlie; Lee, Peter J.; Starch, William; Devred, Arnaud; Larbalestier, David C.


    As part of the ITER conductor qualification process, 3 m long cable-in-conduit conductors (CICCs) were tested at the SULTAN facility under conditions simulating ITER operation so as to establish the current-sharing temperature, T cs, as a function of multiple full Lorentz force loading cycles. After a comprehensive evaluation of both the toroidal field (TF) and the central solenoid (CS) conductors, it was found that T cs degradation was common in long twist pitch TF conductors while short twist pitch CS conductors showed some T cs increase. However, one kind of TF conductors containing superconducting strand fabricated by the Bochvar Institute of Inorganic Materials (VNIINM) avoided T cs degradation despite having long twist pitch. In our earlier metallographic autopsies of long and short twist pitch CS conductors, we observed a substantially greater transverse strand movement under Lorentz force loading for long twist pitch conductors, while short twist pitch conductors had negligible transverse movement. With help from the literature, we concluded that the transverse movement was not the source of T cs degradation but rather an increase of the compressive strain in the Nb3Sn filaments possibly induced by longitudinal movement of the wires. Like all TF conductors this TF VNIINM conductor showed large transverse motions under Lorentz force loading, but T cs actually increased, as in all short twist pitch CS conductors. We here propose that the high surface roughness of the VNIINM strand may be responsible for the suppression of the compressive strain enhancement (characteristic of long twist pitch conductors). It appears that increasing strand surface roughness could improve the performance of long twist pitch CICCs.

  1. Coexistence of mixed phenotype Creutzfeldt-Jakob disease, Lewy body disease and argyrophilic grain disease plus histological features of possible Alzheimer's disease: a multi-protein disorder in an autopsy case. (United States)

    Fernández-Vega, Iván; Ruiz-Ojeda, Javier; Juste, Ramon A; Geijo, Maria; Zarranz, Juan Jose; Sánchez Menoyo, Jose Luis; Vicente-Etxenausia, Ikerne; Mediavilla-García, Jennifer; Guerra-Merino, Isabel


    We report hereby an autopsy case of sporadic mixed phenotype CJD without hereditary burden and a long-term clinical course. An 80-year old man was diagnosed with mild cognitive impairment 27 months before death, caused by bronchopneumonia and severe respiratory impairment. During this time, the patient developed gradual mental deterioration, some sleeping problems and myoclonus. Other clinical manifestations were progressive gait problems, language deterioration, presence of primitive reflexes and irritability. In keeping with those symptoms, a rapidly evolving dementia was clinically suspected. Cerebrospinal fluid test for 14-3-3 protein was negative. However, an abnormal EEG and MRI at end-stage of disease were finally consistent with CJD. Post-mortem examination revealed a massive cortical neuronal loss with associated reactive astrocytosis, also evident in the white matter. Diffuse spongiform changes involving some basal ganglia, especially medial thalamus, some troncoencephalic nuclei, mainly inferior olivary nucleus and the molecular layer of the cerebellum were seen. Immunorreactive deposits for anti-prion protein antibody were present at different areas of the CNS. Additionally, Lewy bodies were observed at the brainstem and amygdala. Furthermore, argirophilic grains together with oligodendroglial coiled bodies and pre-tangle inclusions in the neurons from the limbic system containing hyperphosphorylated 4R tau were noted. To the best of our knowledge, this is the first case of CJD combined with Lewy body disease and argirophilic grain disease. Furthermore, we believe this case is an extremely rare combination of MM2-cortical-type and MM2-thalamic-type sporadic CJD (sCJD), which explains the broad spectrum of MM2-type sCJD findings and symptoms. Moreover, histological features of possible Alzheimer's disease were also reported.

  2. Hepatobiliary alterations in massive biliary ascariasis: histopathological aspects of an autopsy case Lesões hepatobiliares em ascaridíase biliar maciça: aspectos histopatológicos em um caso de autópsia

    Luiz Carlos da Costa Gayotto


    Full Text Available Hepatobiliary alterations found in an autopsy case of massive Biliary Ascariasis, are reported on histological grounds. Severe cholangitis was the main finding, but other changes were also detected, such as pyloric and intestinal metaplasia, hyperplasia of the epithelial lining, with intraductal papillomas and adenomatous proliferation. Remnants of the worm were observed tightly adhered to the epithelium, forming microscopic intrahepatic calculi. Mucopolysaccharides, especially acid, showed to be strongly positive on the luminal border, and in proliferated glands around the ducts. The authors discuss the similarity between such findings and Oriental Cholangiohepatitis, and suggest that inflammation and the presence of the parasitic remnants are responsible for the hyperplastic and metaplastic changes, similarly with what occurs in chlonorchiasis, fascioliasis and schistosomiasis.Os autores apresentam os aspectos histopatológicos encontrados no fígado de um caso de autópsia de Ascaridíase Biliar maciça. A intensa colangite foi o aspecto predominante, mas outras lesões também foram encontradas, tais como metaplasia pilórica e intestinal, hiperplasia epitelial com papilomas intraductais, e por vezes padrão adenomatoso. Restos do helminto foram encontrados fortemente aderidos ao epitélio, sendo intensa a positividade de mucopolissacárides, principalmente ácidos, na borda luminal do epitélio ductal e em glândulas proliferadas ao redor dos ductos. Os autores discutem a semelhança da Ascaridíase Biliar com a Colangio Hepatite Oriental, e sugerem que o processo inflamatório e a presença de restos do verme são responsáveis pelas alterações hiperplásicas e metaplásicas, analogamente ao que ocorre na clonorquíase, fasciolíase e esquistossomose.

    Here we report an autopsy-verified case of frontotemporal lobar degeneration (FTLD)-transactivation responsive region (TAR) DNA binding protein (TDP) type A with upper motor neuron-predominant motor neuron disease mimicking MM2-thalamic-type sporadic Creutzfeldt-Jakob disease (sCJD). A 69-year-old woman presented with an 11-month history of progressive dementia, irritability, insomnia, and gait disturbance without a family history of dementia or prion disease. Neurological examination revealed severe dementia, frontal signs, and exaggerated bilateral tendon reflexes. Periodic sharp-wave complexes were not observed on the electroencephalogram. Brain diffusion MRI did not reveal abnormal changes. An easy Z score (eZIS) analysis for (99m)Tc-ECD-single photon emission computed tomography ((99m)Tc-ECD-SPECT) revealed a bilateral decrease in thalamic regional cerebral blood flow (rCBF). PRNP gene analysis demonstrated methionine homozygosity at codon 129 without mutation. Cerebrospinal fluid (CSF) analysis showed normal levels of both 14-3-3 and total tau proteins. Conversely, prion protein was slowly amplified in the CSF by a real-time quaking-induced conversion assay. Her symptoms deteriorated to a state of akinetic mutism, and she died of sudden cardiac arrest, one year after symptom onset.  Despite the SPECT results supporting a clinical diagnosis of MM2-thalamic-type sCJD, a postmortem assessment revealed that this was a case of FTLD-TDP type A, and excluded prion disease. Thus, this case indicates that whereas a bilateral decreasing thalamic rCBF detected by (99m)Tc-ECD-SPECT can be useful for diagnosing MM2-thalamic-type sCJD, it is not sufficiently specific. Postmortem diagnosis remains the gold standard for the diagnosis of this condition.

    Full Text Available O miocárdio não compactado de ventrículo esquerdo é cardiomiopatia genética em decorrência de uma anormalidade da morfogênese endomiocárdica. Quando presente, geralmente está associado a outras anomalias cardíacas congênitas, sendo raro seu achado isolado sem outras alterações estruturais cardíacas associadas. Desde seu primeiro relato em 1990, a não compactação do miocárdio vem sendo amplamente estudada a fim de se estabelecerem caráter genético, história natural, métodos de diagnóstico, repercussões hemodinâmicas e prognóstico. O objetivo deste estudo foi relatar um caso de miocárdio não compactado isolado de ventrículo esquerdo com estudo de necrópsia.Noncompaction of the ventricular myocardium is a genetic cardiomyopathy due to an alteration in endomyocardial morphogenesis. When present, it is commonly associated with other congenital cardiac diseases, whereas it is rare as an isolated finding without other associated cardiac structural alterations. Since its first report in 1990, the noncompaction of the ventricular myocardium has been widely studied in order to establish its genetic character, natural history, diagnostic methods, hemodynamic repercussions and prognosis. This study aims to report the case of an isolated noncompaction of the left ventricular myocardium with autopsy.

    Blanca Guevara Werlang


    Full Text Available OBJECTIVE: To investigate the applicability and the interrater reliability of a Semi-Structured Interview for psychological autopsy in cases of suicide. METHOD: The Semi-Structured Interview for Psychological Autopsy (SSIPA proposed in this paper consists of four modules which evaluate key-topics associated to suicide. In order to evaluate the instrument's applicability, a sample formed by 42 subjects related to 21 suicide cases was used. The interviews were tape-recorded first and then transcribed. The related material as well as the police inquiry data were presented to four judges. Evaluation of information has been performed with the help of a four-module formulary for decision making: precipitants and/or stressors, motivation, lethality, and intentionality. Data processing, whenever possible, has been accomplished using kappa statistics. When kappa statistic was not applicable, concordance percentage has been used. RESULTS: The SSIPA is applicable because it provides information containing a significant degree of agreement between evaluators, found in one hundred and twenty measurements of judgements made by four judges. There has been significant statistical agreement between the judges in three modules (precipitants and/or stressors, motivation, and intentionality of the model for decision, except in one step of each module, which did not interfere in the final agreement on the present evaluation. In the lethality evaluation module, there has been a 100% agreement between judges. The judgement made by the raters on the four modules have allowed to reach a final agreement regarding the death mode as suicide. CONCLUSION: The results of this study show that it is possible to use a semi-structured instrument for psychological autopsy in cases of suicide, when the interviewees are relatives who accepted to provide information.OBJETIVO: Desenvolver uma entrevista semi-estruturada para autópsia psicológica de casos de suicídio e avaliar a

    Full Text Available PURPOSE: To present the more frequent associations found in autopsies of immunocompromised patients who developed secondary interstitial pneumonia as well as the risk of death (odds ratio in having specific secondary interstitial pneumonia according to the cause of immunocompromise. METHOD: From January 1994 to March 2004, 17,000 autopsies were performed at Hospital das Clínicas, São Paulo University Medical School. After examining the pathology report review, we selected 558 of these autopsies (3.28% from patients aged 15 years or more with primary underlying diseases who developed radiologically diffuse infiltrates of the lung during their hospital course and died after secondary interstitial pneumonia (bronchopneumonia, lobar pneumonia, interstitial pneumonia, diffuse alveolar damage, pulmonary recurrence of underlying disease, drug-induced lung disease, cardiogenic pulmonary edema, or pulmonary embolism. Histology slides were reviewed by experienced pathologists to confirm or not the presence of secondary interstitial pneumonia. Statistical analysis included the Fisher exact test to verify any association between histopathology and the cause of immunocompromise; a logistic regression was used to predict the risk of death for specific histological findings for each of the independent variables in the model. RESULTS: Secondary interstitial pneumonia was histologically represented by diffuse interstitial pneumonitis ranging from mild nonspecific findings (n = 213 to a pattern of diffuse alveolar damage (n = 273. The principal causes of immunocompromise in patients with diffuse alveolar damage were sepsis (136 cases, neoplasia (113 cases, diabetes mellitus (37 cases, and transplantation (48 cases. A high risk of death by pulmonary edema was found for patients with carcinoma of colon. Similarly, in patients with lung cancer or cachexia, A high risk of death by bronchopneumonia (OR = 3.6; OR = 2.6, respectively was found. Pulmonary

    Full Text Available El Misoprostol es un agente farmacológico introducido en el mercado español bajo la forma de un fármaco protector gástrico y comercializado actualmente en asociación con un antinflamatorio. Desde hace varios años, se desarrolla un debate internacional sobre el hecho de que este mismo producto cumple las características de un abortivo extremadamente eficaz. No obstante, el uso inadecuado del Misoprostol puede causar daños severos a la madre y al feto, tanto si el producto se usa con fines abortivos como si se administra accidentalmente durante una gestación, incluso a las dosis recomendadas. Por otra parte, el Misoprostol tiene un rápido metabolismo y no es fácilmente identificable por los laboratorios toxicológicos de referencia, limitando su posible identificación en casos de uso inadecuado, voluntario o accidental. Se presenta un caso de autopsia médico legal tras un posible episodio de aborto inducido por la administración de Misoprostol.Misoprostol is a drug commercialized in Spain as a gastric protector. Nowadays it is sold in our country also associated with diclofenac to prevent gastric damages produced by anti-inflammatories. During the last few years, there has been a public debate in medical press about the fact that Misoprostol has also proved to be an excellent abortive. Nevertheless, when it is not properly used Misoprostol can be the cause of severe damages to the fetus and the mother. This Prostaglandin E1 analog is a drug rapidly metabolized in humans and it is not easy to identify in toxicological analyses. This is the main bias when trying to identify it in forensic cases of accidental damages after using it as a gastric protector or voluntary administration as an abortive. We present a case report about a forensic autopsy following a possible Misoprostol induced abortion.

    Timmann, Christian; Meyer, Christian G


    The cause of death of the Egyptian pharoah Tutankhamun has now for decades been matter of speculation and various hypotheses. A recent article in the Journal of the American Medical Association (JAMA) provided new evidence and suggested malaria, together with Köhler’s disease, as the most probable cause of death of the boy king. We are sceptical towards this elucidation of the cause of death of King Tut and discuss alternative and differential diagnoses, among them, in particular, sickle cell disease and Gauche’s disease.

  19. Autopsy: Traditional Jewish laws and customs "Halacha". (United States)

    Goodman, Norman R; Goodman, Jeffrey L; Hofman, Walter I


    Judaism has many traditions, customs, rules, and laws, which relate to the proper and ethical disposition of a decedent when a Medical Examiner/ Coroner is involved. In almost all United States jurisdictions, statutes mandate the need to determine the cause and manner of death (Coroners' Act PA Pl. 323, num. 130, section 1237). This article is a review of some religious writings, legal precedents, and forensic authorities, which may help to assist the Medical Examiner/Coroner when confronted with a Jewish decedent. There can be flexibility as to the extent that such forensic studies can and should be performed. The final consent and interpretation of the rules, laws, traditions, and customs will rest with the courts and local rabbinic authority.

  20. Scleromyxedema: clinical diagnosis and autopsy findings* (United States)

    Sala, Ana Carolina Bulhões; Cunha, Paulo Rowilson; Pinto, Clóvis Antônio Lopes; Alves, Célia Antônia Xavier de Moraes; Paiva, Ingrid Barreto; Araujo, Ana Paula Vieira


    Scleromyxedema is a rare chronic cutaneous mucinosis of unknown etiology. It is characterized by papular eruption and scleroderma with microscopic evidence of mucin deposition, fibroblast proliferation, and fibrosis. Most patients with scleromyxedema have monoclonal gammopathy and systemic manifestations resulting in significant morbidity and mortality. Several types of treatment have been reported with partial or inconsistent responses. Despite showing unpredictable evolution, systemic consequences of scleromyxedema and treatment side effects may result in death. We describe a rare case of a patient with scleromyxedema without paraproteinemia with systemic involvement that evolved to death despite treatment with cyclophosphamide.

    Full Text Available Anthrax is a rare cause of hemorrhagic meningitis in man. This report illustrates the characteristic hemorrhagic manifestations in the brain of a patient dying of anthrax meningitis secondary to overwhelming bacteremia. Gross examination of the brain revealed a thick dense subarachnoid hemorrhage with numerous petechial hemorrhages in the cortex. Histologically, meningoencephalitis with vascular necrosis, edema, perivascular cortical hemorrhages and clumps of Gram positive bacilli in the vascular lumen and invading vessel wall were the salient features. The anthrax bacillus was isolated from CSF and brain tissue and further its pathogenecity was confirmed by animal inoculation.

    Full Text Available OBJECTIVES: In order to study the morphology and size of muscle fibers, cross sections of biceps brachii samples from autopsies, up to 9 hours after death, and biopsies of 72 subjects were compared. The subjects aged 13 to 84 years in both sexes. METHODS: The samples obtained from autopsies (n=47 were from subjects with sudden death, or who died after acute disease without evidence of neuromuscular involvement. The biopsies (n=25 were from patients with symptoms suggestive of inflammatory or metabolic myopathy, not confirmed morphologically. The lesser diameter of muscle fibers was measured using the ATPase reaction. RESULTS: Morphological analysis showed that aging changes were present from the sixth decade in autopsies, and consisted of atrophy and/or type-grouping. The statistical models adjusted for females in both autopsies and biopsies were linear straight with no variation in fiber size with increasing age. The models adjusted for males in both groups were quadratic, indicating that age influenced the size of different type fibers. In males type 2 were larger than type 1 fibers, and than fibers in females. CONCLUSIONS: These values might be useful as controls, helping interpretation of changes in fiber size in samples obtained from biopsies and autopsies.OBJETIVOS: Para estudar a morfologia e o tamanho das fibras musculares, foram comparadas cortes transversos do bíceps braquial autopsiados, até 9 horas após o óbito, com biopsias musculares, em 72 indivíduos de ambos os sexos e idades entre 13 e 84 anos. MÉTODO: As amostras das autópsias (n=47 foram obtidas de indivíduos que morreram subitamente, ou após uma doença aguda sem evidência de comprometimento neuromuscular. As biópsias (n=25 foram obtidas de pacientes com sintomas sugestivos de miopatias inflamatória ou metabólica, não confirmadas morfologicamente. O diâmetro menor das fibras foi obtido usando a reação de ATPase. RESULTADOS: A análise morfológica mostrou que

Methods The clinical and autopsy data of 3 cases of Waterhouse-Friederichsen syn-drome in the Department of Forensic Medicine, Tongji Medical College were reviewed. Results 2 cases presented with pete-chiasis or ecchymosis, and both were misdiagnosed as allergic purpura and anaphylactic shock. However, cough, asthma and dyspnea were complained as main clinical manifestations in 1 case, which was misdiagnosed as respiratory tract infection. All the patients with acute onset died soon. The forensic pathological diagnosis was acute adrenal function failure ( Waterhouse-Friederichsen syndrome) due to epidemic meningitis in 2 cases and acute adrenal function failure ( Waterhouse-Friederichsen syndrome) in 1 case. Conclusion This disease is rare, rapidly progressive and tends to be misdiagnosed. When diagnosis of Waterhouse-Friederichsen syndrome is definite, the patient should be treated as soon as possible. The effective strategy for treatment would be anti-coagulation with Heparin and anti-fibrinolytic drug and anti-shock remedy.

    Full Text Available Ante la solicitud presentada por los parientes de víctimas no identificadas de la Masacre de la Cárcel de Sabaneta, Maracaibo, Venezuela, un tribunal ordenó la exhumación de cuatro cadáveres, quince días después de haber sido sepultados. Se observó una buena conservación de los restos con apreciable mantenimiento de las estructuras y contornos faciales. Se evidenció que el método de acceso a la cavidad oral empleado en la autopsia bucal pre-inhumación facilitó el abordaje para la autopsia post-exhumación, sin provocar mayor destrucción de los tejidos blandos y permitiendo la correcta manipulación tanto de las estructuras orales como de los dispositivos protésicos aportados como evidencias. En todos los casos se verificó la coincidencia de los datos obtenidos durante la autopsia pre-sepultura. Se concluye que cuando el proceso de inhumación se lleva a cabo siguiendo una adecuada planificación, se facilita una futura recuperación del cadáver cuando esta es requerida para completar el procedimiento de identificación.In view of the petition presented by the relatives of the unidentified victims of the Sabaneta Jail Massacre, Maracaibo, Venezuela, a court ordered the exhumation of four corpses, fifteen days after they were buried. The remains were well preserved, the structure and facial outline were well conserved. It was evidenced that the method of access to the oral cavity employed in the pre-inhumation buccal autopsy facilitated the approach to the post-inhumation autopsy, without causing major destruction of the soft tissues and allowing for the correct manipulation of the oral structures as well as of the prosthetic appliances presented as evidence. In all cases, the coincidence of the data obtained during the pre-burial autopsy was verified. It was concluded that adequate planning of the inhumation process facilitates future recuperation of the bodies when this is required to complete the identification procedure.

    Full Text Available CONTEXT: Primary central nervous system lymphomas (PCNSL are a rare subgroup of lymphomas generally associated with HIV and EBV. OBJECTIVE: To study ten autopsy cases of PCNSL, to describe the neuropathological findings, to characterize the phenotype of the neoplastic cells, to detect EBV in the lesion and to compare the findings with the clinical and laboratory data of the patients. METHOD: The clinical, histological and immunohistochemical data of ten cases of PCNSL, eight cases from patients with AIDS, identified among 265 autopsies of these patients were analyzed. RESULTS: Seven patients were males and the mean age was 40.9 years. The most frequent symptomatology was focal neurologic deficit (70%. Six patients presented with only one lesion. Histologically, densely cellular and polymorphous neoplasms with angiocentrism were observed, in 90% of cases. An association with other diseases was observed in four cases. Most patients had diffuse large B cell non-Hodgkin’s lymphoma. EBV was detected by immunohistochemistry in only one case. The lack of detection of the virus might have been due to the long time of fixation of the brain which might have inactivate epitopes therefore compromising the testing. CONCLUSION: In the present series, PCNSL presented with focal symptoms, with unifocal or multifocal lesions, with a predominant B-cell CD20 positive phenotype, rarely associated with EBV.CONTEXTO: Linfoma primário do sistema nervoso central (LP-SNC é raro subgrupo de linfomas relacionado à AIDS, geralmente associado EBV.

    penetração de agentes infecciosos.The increase in invasive methods currently applied to diagnosis airway upper tract infection leads to a possible increase in vestibular folds (VF lesions. Besides, VF importance in the prevention of the organism against infection pathogens had been stressed and few studies had addressed the microscopic lesions of the VF in autopsied patients because there is no routine VF examination in the postmortem exam. AIM: The aim of this study is morphological microscopic analyses of the VF from autopsied patients and its correlation with basic disease and cause of death. STUDY DESIGN: transversal cohort. MATERIAL AND METHOD: We studied 82 larynges collected during the autopsy exam and performed the Hematoxylin -eosin method for morphological analyses. RESULTS: From the 82 vestibular folds analyzed we observe that 42 (51% showed an inflammatory reaction. In fifteen (18.3% vestibular folds we found lymphoid follicular hyperplasia, in eleven (13.4% diffuse inflammatory infiltrate and in sixteen (19.5% acute inflammatory reactions. Circulatory diseases were the most frequently underlying diseases found, 31 (37.8% and from these 20 (67.8% presented associated vestibular folds inflammatory reaction. The infection diseases were the most frequently cause of death among the patients with inflammatory reaction of the VF. CONCLUSION: Besides the anatomic function, VF seem to have a immunological function preventing lower airway infections. Our study demonstrated inflammatory PV reactions in patients with infections diseases as cause of death; this finding could be a consequence of the sepses that leads the patient to death or a different way used by the organism to prevent infection.

    A K Unmesh


    Full Text Available Background : During forensic evaluation the determination of age of contusions play a very important role. Age of contusions is normally determined based on their colour. Different authors have different interpretations of age of contusions based on colour. Objective : The aim of the present study is to have a first hand information regarding the colour changes occurring in contusions with the passage of time, in our population and also to compare the aging process of contusions in our population with the standard data available Methods: Contusions were classified into small, medium and large. Both naked eye examination of colour of contusions and microscopic examination of contusions were done. Perl’s staining was also done to confirm the presence of pigments. Results: 65 male and 15 female patients were included in the study. Majority of the cases the contusions were due to road traffic accidents. It was observed that in contusions of 24 hrs duration it was red in colour,followed by blue colour for two to three days. Contusions of four to six days were bluish black coloured and green in colour by seventh day. Microscopic examination revealed the presence of RBC in injuries less than 24 hrs duration. Lymphocytes and polymorphs were prominent in third and fourth day of injury. Perl’s stain was positive from the fifth day onwards. Conclusion : The observations of colour tone of injury and histopathological findings including special staining techniques like Perl’s stain can help the forensic pathologist to a certain extent in dating the age of medium sized contusion in moderately nourished adult subjects during the initial phases of injury.

    Emoto, Yuko; Yoshizawa, Katsuhiko; Shikata, Nobuaki; Tsubura, Airo; Nagasaki, Yasushi


    Cresol, which is used as a disinfectant and insecticide, has erosive effects on epidermal and epithelial tissues in the body. Oral exposure causes gastrointestinal corrosive injuries as a direct chemical burn. We report herein a case of suicidal poisoning by ingestion of cresol solution. An octogenarian man with depression was found dead approximately 14 h after exposure to less than 500 mL of saponated cresol solution. Macroscopically, corrosive lesions such as red-to-brown-colored epithelium and edematous thickening of walls were seen in the skin, mouth, oral cavity, esophagus, and stomach. Histopathologically, coagulative necrosis and vascular dilatation were detected from mucosal to muscular layers in the esophagus, stomach, and duodenum. Congestive edema of the lungs, edematous changes in the brain, and proximal tubular necrosis of the kidneys were seen, suggesting acute circulatory disturbance due to shock. This human case offers valuable information on the direct irritation and shock induced by systemic exposure to corrosive substances.

    Multifetal gestations are high risk pregnancies with higher perinatal morbidity and mortality. Multifetal gestations are subject to unique complications including conjoined twins, twin-to-twin transfusion syndrome (TTTS), acardiac twins, twin embization of co-twin demise and heterotopic pregnancies. Prenatal sonographic diagnosis of types and complications of multifetal gestations is important for antenatal care and prediction of fetal outcome. This study was performed to present the prenatal ultrasonographic findings and pathologic findings of the unique complications of twin pregnancy. Acardia is a lethal anomaly occurring in 1% of monozygotic twin. The acardiac twin has a parasitic existence and depends on the donor (pump) twin for its blood supply via placental anastomoses and retrograde perfusion of umbilical cord. This twin reversed arterial perfusion (TRAP) sequence is a most extreme manifestation on the TTTS. Doppler verification reversed flow in umbilical cord of the acardiac twin confirms the diagnosis.

    Full Text Available The most dynamic feature of the South Korean economy in the late 20th century is the emergence of the country as a major destination for foreign investors. However, because the market has been closed to outsiders, for almost two decades, except for certain industries, Korea is as yet an unknown entity among the global business community. This acts as a deterrent to market entry. It is evident that among the economic and business literature there has been limited emphasis on the cultural and other complications such as the position and influence of the chaebol (a group of mostly family owned conglomerates in Korea that exists for foreign businesses in the Republic of Korea. This paper attempts to crystallize some of the key cultural issues, examine their relevance and highlight some consequences of the lack of understanding of these cultural issues for the world's leading multinational corporations wishing to enter the Korean market.

  18. Surveillance of abused drugs in forensic autopsy cases in Norway

    Directory of Open Access Journals (Sweden)

    Svetlana V. Konstantinova-Larsen


    Full Text Available High drug related mortality has been registered in Norway. Although comparison between countries relies on a standard international coding system of diseases, different practices in verifying cause of death and applying codes could lead to variation. The comparison gives no information on drug findings or drug patterns underlying the cause of deaths. To evaluate deaths involving illicit drugs in Norway, we examined drug patterns in 2735 forensically examined post-mortem samples collected from 15-64 year-old individuals from 2000 to 2009. There were four times as many men as women among the deceased illicit drug users, and the majority were in the age group 25-44 years. The number of deceased showing signs of illicit drug use has gradually declined during the study period. The decline was found among younger individuals, while a larger proportion of the deceased were above 45 years of age in 2009, compared to 2000. Cases positive for heroin, ethanol, ecstasy and flunitrazepam were fewer in 2009, while the prevalence of amphetamine, cannabis, methadone and other opioids has increased. The prevalence of methamphetamine has increased ten fold, and the prevalence of benzodiazepines doubled. Thus, the drug pattern and age of the deceased has changed markedly during the last 10 years. Heroin and ethanol use has partly been substituted by use of amphetamines, cannabis, benzodiazepines and other opioids. This change could possibly be explained by the prolonged survival of drug users on substitution treatment and by the reduced toxicity of consumed drugs.

    Ascaris lumbricoides or roundworms' propensity to produce large number of eggs that are resistant to extremes of environmental conditions have made them one of the highly prevalent and geographically well distributed nematodes among poor socio-economic regions throughout the world. We present an unusual case of fatal gastro-intestinal ascariasis where general neglect, and firm and prolonged reliance on traditional healing methods led to aggregation of roundworms to such an extent that otherwise seems improbable in modern times and, hence, is worth reporting.

  20. Ernest Hemingway: a psychological autopsy of a suicide. (United States)

    Martin, Christopher D


    Much has been written about Ernest Hemingway, including discussion of his well-documented mood disorder, alcoholism, and suicide. However, a thorough biopsychosocial approach capable of integrating the various threads of the author's complex psychiatric picture has yet to be applied. Application of such a psychiatric view to the case of Ernest Hemingway in an effort toward better understanding of the author's experience with illness and the tragic outcome is the aim of this investigation. Thus, Hemingway's life is examined through a review and discussion of biographies, psychiatric literature, personal correspondence, photography, and medical records. Significant evidence exists to support the diagnoses of bipolar disorder, alcohol dependence, traumatic brain injury, and probable borderline and narcissistic personality traits. Late in life, Hemingway also developed symptoms of psychosis likely related to his underlying affective illness and superimposed alcoholism and traumatic brain injury. Hemingway utilized a variety of defense mechanisms, including self-medication with alcohol, a lifestyle of aggressive, risk-taking sportsmanship, and writing, in order to cope with the suffering caused by the complex comorbidity of his interrelated psychiatric disorders. Ultimately, Hemingway's defense mechanisms failed, overwhelmed by the burden of his complex comorbid illness, resulting in his suicide. However, despite suffering from multiple psychiatric disorders, Hemingway was able to live a vibrant life until the age of 61 and within that time contribute immortal works of fiction to the literary canon.

    Full Text Available Twenty eight fatal cases out of the 97 cases of methyl alcohol (MA poisoning admitted to K. E. M. Hospital in August 1988 during a single outbreak were studied. The latent period between consumption of the drink and development of symptoms was variable (range 7 1/2 hours to 60 hours. CNS symptoms were predominant (75% of cases and shock either at admission or as a late event was seen in 89% of the cases. Blurring of vision was seen in 42.8% and blindness in 10.7% of cases. Minimum fatal period was 7 1/2 hours and maximum was 12 days. Methanol levels in blood and viscera were variable (average 155.8 mg%, max. 420.4 mg%. In 4 cases, significant amount of MA was detected in stomach contents 5-12 days after consumption of MA, raising the question of resecretion of MA in stomach. Shrinkage and degeneration of neurons in the parietal cortex was seen in 85.7% of cases. Putamental degeneration and necrosis was seen in 7.14%. Haemorrhage (3.5% and sponginess (7.14% was observed in the optic chiasma. Severe renal tubular degeneration and patchy necrosis was seen in all cases. Fatty changes (67.8% and microvesicular fat (42.5% were seen in the hepatocytes.

    Full Text Available In its attempt to realize the intervention program to saving newborn babies with asphyxia, the Ministry of Health will initiate to train midwives in the village in order to that they know how to operate resuscitation equipment to save neonatal baby with asphyxia. The intervention program his dubbed successful if the mortality proportion due if asphyxia decreased to half as targeted. The survey was conducted in the rural area of Cirebon district. The sample was 200 neonatal death babies, calculated using the hypothesis test with different proportion; p1 0.3 (30% neonatal death cause of asphyxia, according household health survey 2001, p2 0.15, α 0.05, β 0.2, (l-β 0.8. Neonatal dead cases happened within 12 months prior to the survey were identified by rural midwives out of their personal records. The death cases were followed up by interviewing the mother of the neonatal baby concerning its birth, illness or disorder histories before death. The diagnosis of the diseases were based on the International Classification of Diseases 10 and Wigglesworth classification, determined in union by NIHRD researchers and neonatologists. The neonatal mortality rate was 13 out of 1,000 live births. The major cause of early neonatal mortality was respiration disorder mainly caused by birth asphyxia (45%, of which 90 percent could be intervened by doing resuscitation (for babies weighed more than 1.000 gram. The second and third order of the mortality causes was infection (22% and congenital disorders (11% respectively. The major cause of late neonatal mortality was infection (56%, followed by low birth weight and prematurely born, as well as neonatal jaundice (14 percent each, and congenital disorder comes in the third place. The option to handle asphyxia with the early neonatal babies is the right effort to decrease the neonatal mortality rate. And to achieve the utmost result, it is necessary that the rural midwives maintain their standard performance (in terms of quantity and quality in their basic midwifery services, i.e. providing pregnancy health care and detecting as early as possible maternal diseases/complication. Besides, there must be continuous monitoring and adequate guidance from the counselor team from referral hospital.

  4. Autopsy-proven determinants of immediate fire death in lungs. (United States)

    de Paiva, Luiz A S; Parra, Edwin R; da Rosa, Danieli C; Farhat, Cecília; Delmonte, Carlos; Capelozzi, Vera L


    In immediate fire deaths, pulmonary injury may be the main source of mortality, being important to document the histologic findings for the purpose of excluding other modes of death, such as from asphyxia with no gross findings. In this context, a group of morphologic determinants have been targeted with useful makers of pulmonary injury. To facilitate the determination of whether an individual was deceased before the start of a fire and validate the importance of parenchymal alterations in pulmonary injury in fire deaths, we studied lungs in victims of fire (N = 28) and suffocation (N = 40), creating a mathematical model using cluster analysis. For this purpose, a semiquantitative analysis of the distal parenchyma was performed to evaluate the amount of bronchiolar dilatation, overinsufflation (ductal and alveolar), collapse (ductal and alveolar), passive congestion, alveolar edema, and hemorrhage (interstitial and alveolar). These 7 histologic determinants were useful to discriminate fire (bronchiolar dilatation, ductal overinsuflation, alveolar overinsuflation, alveolar hemorrhage) from suffocation lung injuries (alveolar collapse, congestion, and edema). We conclude that these determinants should be included in the routine of forensic pathology.

  5. Correlation between surgical lung biopsy and autopsy findings and clinical data in patients with diffuse pulmonary infiltrates and acute respiratory failure Correlação entre achados de biópsia pulmonar cirúrgica e de autópsia e dados clínicos em pacientes com infiltrados pulmonares difusos e insuficiência respiratória aguda

    Full Text Available INTRODUCTION: Surgical lung biopsy is an invasive procedure performed when other procedures have failed to provide an urgent and specific diagnosis, but there may be reluctance to perform it in critically ill patients with diffuse pulmonary infiltrates. PURPOSE: To evaluate the diagnostic accuracy, the changes in therapy and survival of patients with diffuse lung infiltrates, mostly presenting acute respiratory failure, who underwent surgical biopsy. METHODS: We retrospectively examined medical records and surgical lung biopsies from 1982 to 2003 of 63 patients older than 18 years with diffuse infiltrates. Clinical diagnoses were compared to histopathological ones, from biopsies and autopsies. Laboratory and epidemiological data were evaluated, and their relationship to hospital survival was analyzed. RESULTS: All histological specimens exhibited abnormalities, mostly presenting benign/inflammatory etiologies. Fifteen patients had an etiologic factor determined in biopsy, most commonly Mycobacterium tuberculosis. The preoperative diagnosis was rectified in 37 patients. Autopsies were obtained in 25 patients and confirmed biopsy results in 72% of cases. Therapy was changed for 65% of patients based on biopsy results. Forty-nine percent of patients survived to be discharged from the hospital. Characteristics that differed significantly between survivors and nonsurvivors included sex (P = 0.05, presence of comorbidity (P = 0.05, SpO2 (P = 0.05, and presence of diffuse alveolar damage in the biopsy (P = 0.004. CONCLUSION: Surgical lung biopsy provided a specific, accurate etiologic diagnosis in many patients with diffuse pulmonary infiltrates when clinical improvement did not occur after standard treatment. Surgical lung biopsy may reveal a specific diagnosis that requires distinct treatment, and it would probably have an impact in lowering the mortality of these patients.INTRODUÇÃO: A biópsia pulmonar cirúrgica é um procedimento invasivo

    Full Text Available A retrospective study was conducted in nine patients with rabies admitted to a hospital of Fortaleza, Brazil. Autopsy was performed in all cases. The ages ranged from three to 81 years and six were males. They all were bitten by dogs. The time between the accident and the hospital admission ranged from 20 to 120 days (mean 45 ± 34 days. The time until death ranged from one to nine days (mean 3.3 ± 5.5 days. The signs and symptoms presented were fever, hydrophobia, aerophobia, agitation, disorientation, dyspnea, sialorrhea, vomiting, oliguria, sore throat, pain and hypoesthesia in the site of the bite, headache, syncope, cough, hematemesis, mydriasis, hematuria, constipation, cervical pain and priapism. In three out of six patients, there was evidence of acute renal failure, defined as serum creatinine > 1.4 mg/dL. The post-mortem findings in the kidneys were mild to moderate glomerular congestion and mild to intense peritubular capillary congestion. Acute tubular necrosis was seen in only two cases. This study shows some evidence of renal involvement in rabies. Histopathologic findings are nonspecific, so hemodynamic instability, caused by autonomic dysfunction, hydrophobia and dehydration must be responsible for acute renal failure in rabies.Foi realizado estudo retrospectivo de nove casos de raiva internados em um hospital de Fortaleza, Brasil.

    Moon, H R; Chi, J G; Yeon, K M; Suh, Y L; Sung, R H; Kim, B I; Rhi, J L; Kim, S H


    We report the first case of Menkes' disease in Korea, occurring in a 1 1/2 year old boy with characteristic clinical, arteriographic and pathologic features. Postmortem examination revealed widespread neuronal destruction and abnormally tortuous and elongated large arteries including cerebral, visceral and limb vessels. Microscopically, many of the hairs formed were twisted (pili torti), of varying caliber (monilethrix), and fractured (trichorrhexis nodosa). In the radioactivated analysis of scalp hair, copper elements was not found. The abnormal vessels were characterized by fragmentation and disruption of the internal elastic lamina with intimal proliferation. The neuronal destruction was widespread in the cerebral gray matter and in the cerebellum, and there was associated gliosis. The changes in the cerebellum were particularly severe, with neuronal loss in the internal granular cell layer. Many Purkinje cells were lost, and the remainder showed unusual dendritic sprouts from the cell body and grotesque proliferation of dendritic tree. In other organs, mild chronic peribronchitis, and scattered foci of immature glomeruli in renal cortex were noted.

    Sajish Jacob


    Full Text Available Central pontine myelinolysis is a demyelinating disorder characterized by the loss of myelin in the center of the basis pontis usually caused by rapid correction of chronic hyponatremia. The clinical features vary depending on the extent of involvement. Demyelination can occur outside the pons as well and diagnosis can be challenging if both pontine and extrapontine areas are involved. We herein report a case of myelinolysis involving pons, lateral geniculate bodies, subependymal region, and spinal cord. To the best of our knowledge, this case represents the second case of spinal cord involvement in osmotic demyelination syndrome and the first case of involvement of thoracic region of spinal cord.

Rouse, President of the American Medical Association (the AMA in 1967. His position at the pinnacle of the most powerful country's most powerful medical organization certainly gave him the authority to say that with confidence. "People respect doctors. In fact, 92% of the public feels most doctors can be trusted. People in the medical therapy professions are admired and the communities they serve reward them well for their work. Doctors averaged $31,400 a year in 1967 and their median income was $32,170 in 1968. These figures are approximately five times the average and median incomes for the general population. "Medically speaking, things seem to be going well. The drama of headlines about organ transplants and new medical advances in the laboratory also serve to indicate that the System that provides health care for Americans does its job splendidly.

  13. An autopsy case of sudden unexpected death due to a glial cyst of the pineal gland. (United States)

    Na, Joo-Young; Lee, Kyung-Hwa; Kim, Hyung-Seok; Park, Jong-Tae


    Pineal cysts are usually asymptomatic; however, they may rarely cause symptoms such as chronic headache, paroxysmal headache with gaze paresis, postural syncope, loss of consciousness, and sudden death. A 30-year-old woman with no specific medical history except chronic headache was found collapsed in a public toilet per se. Postmortem examination revealed no external injuries or internal diseases except a cystic lesion of the pineal gland. Histologic examination showed an internal cyst surrounded by glial tissues and pineal parenchyma that was diagnosed as a glial cyst of the pineal gland. Although the pineal cyst cannot be confirmed as the cause of death, it was considered, as no other cause was evident. Herein, we report a pineal cyst considered as an assumed cause of death.

  15. [Acute edematous encephalopathy presenting with refractory generalized status epilepticus: an autopsy case]. (United States)

    Yamashita, M; Yamamoto, T; Yasuda, T


    A previously healthy, 29-year-old man developed generalized convulsion with disturbed consciousness 3 days after the flu-like symptoms. On the next day, his convulsion evolved into generalized status epilepticus (GSE) that was unresponsive to administration of various anticonvulsants. Then, intravenous anesthetic agents, including midazolam, propofol and vecuronium sodium, were continuously infused. During the following 9 days, despite of high-dose infusion of these anesthetic agents, his GSE could not be suppressed, and complex partial seizure with secondary generalization frequently occurred. The patient was comatose and mechanically ventilated, whereas the brainstem reflexes were preserved. Electroencephalogram revealed a diffuse slowing of the background activity and occasional focal spike and wave complexes with secondary generalization. Cerebrospinal fluid analysis showed pleocytosis and elevated protein concentration. Cranial CT scans obtained on day 8 demonstrated brain edema. On day 10, his GSE ceased with abolition of the brainstem reflexes, and he lapsed into brain death resulting from the progressive brain edema. Over the following six days, his systemic circulation gradually worsened, and he died on day 16. On postmortem examination, the brain was markedly edematous and showed the findings consistent with acute anoxic encephalopathy with extensive circulatory stasis. Mild gliosis was observed in the insular cortex, yet no evidence of inflammatory disease was found throughout the brain. This patient was characterized by acutely progressive severe brain edema without inflammatory changes, suggesting that his primary disease was acute toxic encephalopathy presumably induced by viral infection. His GSE was refractory and unresponsive to the intensive treatment with the intravenous anesthetic agents. This case epitomizes the difficulties in controlling refractory seizures in some patients with encephalopathy or encephalitis.

    Full Text Available Poison is a substance introduced in the body to produce ill - effect, disease or death. It may be of any origin like synthetic, mineral, animal or vegetable. Death due to poisoning is mostly prevalent in the developing countries, of the total burden of acute pesticide poisoning; the majority of deaths are from deliberate self - poisoning with organophosphorus pesticides, aluminium phosphide and paraquat. Exposure to pesticides is usually occupational, accidental or suicidal. In India very few research works hav e been undertaken on histopathological changes of liver in different poisoning. In this part of our country a sizable number of cases of poisoning due to insecticides & alcohol are reported. So this current study intends to find out different histopatholog ical changes of liver in insecticidal & alcohol poisoning with regards to time interval between poisoning and death. In our 1 year (November 2012 - October 2013 of study we got 143 victims who died due to insecticidal and alcohol poisoning, out of which 132 cases show significant histopathological changes in liver. In this study male subjects (60.83% outnumber female (39.17% victims and most common age group affected in this study is between 20 - 40 years.

  18. Secondary skull fractures in head wounds inflicted by captive bolt guns: autopsy findings and experimental simulation. (United States)

    Perdekamp, Markus Grosse; Kneubuehl, Beat P; Ishikawa, Takaki; Nadjem, Hadi; Kromeier, Jan; Pollak, Stefan; Thierauf, Annette


    Apart from one article published by Rabl and Sigrist in 1992 (Rechtsmedizin 2:156-158), there are no further reports on secondary skull fractures in shots from captive bolt guns. Up to now, the pertinent literature places particular emphasis on the absence of indirect lesions away from the impact point, when dealing with the wounding capacity of slaughterer's guns. The recent observation of two suicidal head injuries accompanied by skull fractures far away from the bolt's path gave occasion to experimental studies using simulants (glycerin soap, balls from gelatin) and skull–brain models. As far as ballistic soap was concerned, the dimensions of the bolt's channel were assessed by multi-slice computed tomography before cutting the blocks open. The test shots to gelatin balls and to skull-brain models were documented by means of a high-speed motion camera. As expected, the typical temporary cavity effect of bullets fired from conventional guns could not be observed when captive bolt stunners were discharged. Nevertheless, the visualized transfer of kinetic energy justifies the assumption that the secondary fractures seen in thin parts of the skull were caused by a hydraulic burst effect.

    Vascular permeability, thrombocytopenia, liver pathology, complement activation, and altered hemostasis accompanying a febrile disease are the hallmarks of the dengue hemorrhagic fever/dengue shock syndrome, a major arthropod-borne viral disease that causes significant morbidity and mortality throughout tropical countries. We studied tissues from 13 children who died of acute dengue hemorrhagic fever/dengue shock syndrome at the Childrens' Hospital, Yangon, Myanmar. Dengue viral RNA from each of the 4 dengue viruses (DENVs) was detected by reverse transcriptase polymerase chain reaction in 11 cases, and dengue viral proteins (envelope, NS1, or NS3) were detected in 1 or more tissues from all 13 cases. Formalin-fixed and frozen tissues were studied for evidence of virus infection using monoclonal antibodies against DENV structural and nonstructural antigens (E, NS1, and nonsecreting NS3). In the liver, DENV infection occurred in hepatocytes and Kupffer cells but not in endothelial cells. Liver damage was associated with deposition on hepatocytes of complement components of both classical and alternative pathways. Evidence of dengue viral replication was observed in macrophage-like cells in spleens and lymph nodes. No dengue antigens were detected in endothelial cells in any organ. Germinal centers of the spleen and lymph nodes showed a marked reduction in the number of lymphocytes that were replaced by eosinophilic deposits, which contained dengue antigens as well as immunoglobulins, and complement components (C3, C1q, and C9). The latter findings had previously been reported but overlooked as a diagnostic feature.

    Caffeine (1,3,7-trimethylxanthine) is a popular mild central nervous system stimulant found in the leaves, seeds and fruits of various plants and in foodstuffs such as coffee, tea, and chocolate, among others. Caffeine is widely used and is not associated with severe side effects when consumed at relatively low doses. Although rarely observed, overdoses can occur. However, only a few fatal caffeine intoxication cases have been reported in the literature. Herein, we report the pathological exa...

  4. [An autopsy case of head injury with a manic-depressive states (author's transl)]. (United States)

    Deshimaru, M; Miyakawa, T; Suzuki, T


    M. M. a man aged 49. He suffered from a head injury at the aged of 41. At that time he lost consciousness for a few minutes and he was diagnosed as a consquassatio cerebri. The sequelaes of his head injury were a change of character and a disturbance of autonomic nerve function. The changes of character were decreased of activity, lie-down for all day, decrease of speech and depressive mode, and occasionally he was ill-humored, restless and irritative. Periodically he became euphoris, talkative and childisch. He had a disturbance of autonomic nerve function which became worse in parallel to the depressive states. We speculated that character changes, such as manic-depressive states and disturbances of autonomic nerve function were due to the bruising of the bilateral orbital surfaces of frontal lobes.

  5. Unsuspected meningioma in a patient with pituitary gigantism. Case report with autopsy findings

    Energy Technology Data Exchange (ETDEWEB)

    Stock, J.M.; Ghatak, N.R.; Oppenheimer, J.H.


    A unique example of a clinically unsuspected large parasellar meningioma is described in a 36-yr-old pituitary giant who had been treated initially with conventional irradiation, subsequently by surgical excision of an acidophil adenoma, and ultimately with medroxyprogesterone acetate (MPA) prior to his demise. The patient died of increased intracranial pressure resulting from a combined mass effect of the meningioma and recurrent tumor. The relationship between radiation and the development of the meningioma is discussed, as well as the fine ultrastructure of a highly functioning acidophil adenoma.

  6. Sudden death due to an unrecognized cardiac hydatid cyst: three medicolegal autopsy cases. (United States)

    Pakis, Isil; Akyildiz, Elif Ulker; Karayel, Ferah; Turan, Arzu Akcay; Senel, Berna; Ozbay, Mehmet; Cetin, Gursel


    Echinococcosis is a human infection caused by the larval stage of Echinococcocus granulosus. The most common sites of infection are the liver and the lungs. Cardiac hydatid cysts are very rare, even in regions where hydatic cysts are endemic (the Mediterranean, South America, Africa, and Australia). It has been reported that cardiac involvement is seen in about 0.5-3% of human echinococcosis cases. Three cases of cardiac hydatid disease that caused sudden death and which were histopathologically diagnosed are reported. Cardiac echinococcosis is rare, but due to its insidious presentation and affinity to cause sudden death, it is important that it be identified in the histopathological examination.

  7. Cardiac injuries caused by blunt trauma: an autopsy based assessment of the injury pattern. (United States)

    Turan, Arzu Akcay; Karayel, Ferah Anik; Akyildiz, Elif; Pakis, Isil; Uzun, Ibrahim; Gurpinar, Kagan; Atilmis, Umit; Kir, Ziya


    Nonpenetrating chest trauma with injury to the heart and aorta has become increasingly common, particularly as a result of rapid deceleration in high-speed vehicular accidents, over the past 2-3 decades. The high mortality rate of cardiac injuries and possible late onset complications make blunt cardiac injuries an important challenging point for legal medicine. One hundred and ninety cases with blunt cardiac injuries in a period of 3 years were analyzed retrospectively in terms of patterns of cardiac injury, survival times, and demographic profiles of the cases in this study.

  10. Concentration of organochlorines in human brain, liver, and adipose tissue autopsy samples from Greenland

    DEFF Research Database (Denmark)

    Dewailly, Éric; Mulvad, Gert; Pedersen, Henning S.;


    Organochlorines are persistent lipophilic compounds that accumulate in Inuit people living in circumpolar countries. Organochlorines accumulate as a result of the Inuits' large consumption of sea mammal fat; however, available data are limited to blood lipids, milk fat, and adipose tissue. We...... report results of organochlorine determination in liver, brain, omental fat, and subcutaneous abdominal fat samples collected from deceased Greenlanders between 1992 and 1994. Eleven chlorinated pesticides and 14 polychlorinated biphenyl congeners were measured in tissue lipid extracts by high......-resolution gas chromatography with electron capture detection. Mean concentrations of polychlorinated biphenyls, 2, 2'-bis(4-chlorophenyl)-1,1-dichloroethylene, ss-hexachlorocyclohexane, hexachlorobenzene, mirex, trans-nonachlor, and oxychlordane in adipose tissue samples from Greenlanders were 3-34-fold higher...

  11. The PIVKA II test: the first reliable coagulation test for autopsy investigations. (United States)

    Rutty, G N; Woolley, A; Brookfield, C; Shepherd, F; Kitchen, S


    To date there is no routinely used reliable diagnostic test that can be performed in the post-mortem period to investigate whether a deceased had a coagulation disorder. This paper describes a series of experiments to assess the use of an antigen-based method to investigate the vitamin K-dependent factor II function in the deceased. It illustrates that by using this approach the functional status of factor II can be investigated in the post-mortem period. The abnormal proteins that are investigated by this method appear to remain stable for at least 72 h and potentially up to at least 7 days. The method that is illustrated could thus be reliably used in the post-mortem period to identify a natural or drug-induced factor II abnormality. The potential for other protein components of the coagulation cascade to be investigated by similar antigen-based methodology is suggested.

  12. Contribution of cerebrovascular disease in autopsy confirmed neurodegenerative disease cases in the National Alzheimer's Coordinating Centre. (United States)

    Toledo, Jon B; Arnold, Steven E; Raible, Kevin; Brettschneider, Johannes; Xie, Sharon X; Grossman, Murray; Monsell, Sarah E; Kukull, Walter A; Trojanowski, John Q


    Cerebrovascular disease and vascular risk factors are associated with Alzheimer's disease, but the evidence for their association with other neurodegenerative disorders is limited. Therefore, we compared the prevalence of cerebrovascular disease, vascular pathology and vascular risk factors in a wide range of neurodegenerative diseases and correlate them with dementia severity. Presence of cerebrovascular disease, vascular pathology and vascular risk factors was studied in 5715 cases of the National Alzheimer's Coordinating Centre database with a single neurodegenerative disease diagnosis (Alzheimer's disease, frontotemporal lobar degeneration due to tau, and TAR DNA-binding protein 43 immunoreactive deposits, α-synucleinopathies, hippocampal sclerosis and prion disease) based on a neuropathological examination with or without cerebrovascular disease, defined neuropathologically. In addition, 210 'unremarkable brain' cases without cognitive impairment, and 280 cases with pure cerebrovascular disease were included for comparison. Cases with cerebrovascular disease were older than those without cerebrovascular disease in all the groups except for those with hippocampal sclerosis. After controlling for age and gender as fixed effects and centre as a random effect, we observed that α-synucleinopathies, frontotemporal lobar degeneration due to tau and TAR DNA-binding protein 43, and prion disease showed a lower prevalence of coincident cerebrovascular disease than patients with Alzheimer's disease, and this was more significant in younger subjects. When cerebrovascular disease was also present, patients with Alzheimer's disease and patients with α-synucleinopathy showed relatively lower burdens of their respective lesions than those without cerebrovascular disease in the context of comparable severity of dementia at time of death. Concurrent cerebrovascular disease is a common neuropathological finding in aged subjects with dementia, is more common in Alzheimer's disease than in other neurodegenerative disorders, especially in younger subjects, and lowers the threshold for dementia due to Alzheimer's disease and α-synucleinopathies, which suggests that these disorders should be targeted by treatments for cerebrovascular disease.

  15. Connected speech as a marker of disease progression in autopsy-proven Alzheimer's disease. (United States)

    Ahmed, Samrah; Haigh, Anne-Marie F; de Jager, Celeste A; Garrard, Peter


    Although an insidious history of episodic memory difficulty is a typical presenting symptom of Alzheimer's disease, detailed neuropsychological profiling frequently demonstrates deficits in other cognitive domains, including language. Previous studies from our group have shown that language changes may be reflected in connected speech production in the earliest stages of typical Alzheimer's disease. The aim of the present study was to identify features of connected speech that could be used to examine longitudinal profiles of impairment in Alzheimer's disease. Samples of connected speech were obtained from 15 former participants in a longitudinal cohort study of ageing and dementia, in whom Alzheimer's disease was diagnosed during life and confirmed at post-mortem. All patients met clinical and neuropsychological criteria for mild cognitive impairment between 6 and 18 months before converting to a status of probable Alzheimer's disease. In a subset of these patients neuropsychological data were available, both at the point of conversion to Alzheimer's disease, and after disease severity had progressed from the mild to moderate stage. Connected speech samples from these patients were examined at later disease stages. Spoken language samples were obtained using the Cookie Theft picture description task. Samples were analysed using measures of syntactic complexity, lexical content, speech production, fluency and semantic content. Individual case analysis revealed that subtle changes in language were evident during the prodromal stages of Alzheimer's disease, with two-thirds of patients with mild cognitive impairment showing significant but heterogeneous changes in connected speech. However, impairments at the mild cognitive impairment stage did not necessarily entail deficits at mild or moderate stages of disease, suggesting non-language influences on some aspects of performance. Subsequent examination of these measures revealed significant linear trends over the three stages of disease in syntactic complexity, semantic and lexical content. The findings suggest, first, that there is a progressive disruption in language integrity, detectable from the prodromal stage in a subset of patients with Alzheimer's disease, and secondly that measures of semantic and lexical content and syntactic complexity best capture the global progression of linguistic impairment through the successive clinical stages of disease. The identification of disease-specific language impairment in prodromal Alzheimer's disease could enhance clinicians' ability to distinguish probable Alzheimer's disease from changes attributable to ageing, while longitudinal assessment could provide a simple approach to disease monitoring in therapeutic trials.

  16. [An autopsy case of atypical Friedreich's ataxia with chronic idiopathic intestinal pseudo-obstruction]. (United States)

    Nagata, T; Aoki, M; Hasegawa, T; Shiga, Y; Hayashi, T; Higuchi, J; Abe, K; Tanno, T; Konno, H; Itoyama, Y


    We report a 58-year-old man with slowly progressive muscle atrophy and weakness in the four extremities, accompanying cerebellar ataxia and sensory impairment of all modalities. He was a product of consanguineous marriage. His neurological manifestations began in childhood. He was admitted to our hospital because of marked abdominal distension and pretibial edema with hypoalbuminemia and hyperlipidemia. Neuroimaging studies showed marked atrophy of the cerebellum and spinal cord. Nerve conduction studies presented with slowing and sural nerve biopsy revealed demyelination with onion-bulbs. Abdominal distension was interpreted to be caused by chronic idiopathic intestinal pseudo-obstruction (CIIP), leading to protein-losing gastroenteropathy and hypalbuminemia caused by the CIIP. He died of DIC by myelodysplasic syndrome and DIC, two years later. Postmortem study demonstrated with severe loss of anterior horn cells and gliosis in the spinal cord. The Clarke's column was also affected. There was symmetrical degeneration in the dorsal column and corticospinal tracts. The cerebellum showed atrophy of molecular layer, prominent loss of Purkinje's cells and sparse granular cell layer, but no obvious change in the dentate nucleus. Neuronal loss in the dorsal root ganglia was remarkable. There were no alternations in the cerebral cortex, striatum, thalamus, subthalamic nucleus, and pontine nucleus, except for mild changes in substantia nigra and inferior olivary nucleus. This case was clinically suspected either of variant of Friedreich's ataxia or an early onset ataxia associated with hypoalbuminemia (EOAHA), although marked autonomic dysfunction was atypical. But the postmortem study, demonstrated with marked neuronal loss in anterior horn cells and cerebellan cortex and rather suggested an independent category of this case.

  19. Contiguous ABCD1 DXS1357E deletion syndrome: report of an autopsy case. (United States)

    Contiguous ABCD1 DXS1357E deletion syndrome (CADDS) is a contiguous deletion syndrome involving the ABCD1 and DXS1357E/BAP31 genes on Xq28. Although ABCD1 is responsible for X-linked adrenoleukodystrophy (X-ALD), its phenotype differs from that of CADDS, which manifests with many features of Zellweger syndrome (ZS), including severe growth and developmental retardation, liver dysfunction, cholestasis and early infantile death. We report here the fourth case of CADDS, in which a boy had dysmorphic features, including a flat orbital edge, hypoplastic nose, micrognathia, inguinal hernia, micropenis, cryptorchidism and club feet, all of which are shared by ZS. The patient achieved no developmental milestones and died of pneumonia at 8 months. Biochemical studies demonstrated abnormal metabolism of very long chain fatty acids, which was higher than that seen in X-ALD. Immunocytochemistry and Western blot showed the absence of ALD protein (ALDP) despite the presence of other peroxisomal proteins. Pathological studies disclosed a small brain with hypomyelination and secondary hypoxic-ischemic changes. Neuronal heterotopia in the white matter and leptomeningeal glioneuronal heterotopia indicated a neuronal migration disorder. The liver showed fibrosis and cholestasis. The thymus and adrenal glands were hypoplastic. Array comparative genomic hybridization (CGH) analysis suggested that the deletion was a genomic rearrangement in the 90-kb span starting in DXS1357E/BACP31 exon 4 and included ABCD1, PLXNB3, SRPK3, IDH3G and SSR4, ending in PDZD4 exon 8. Thus, the absence of ALDP, when combined with defects in the B-cell antigen receptor associated protein 31 (BAP31) and other factors, severely affects VLCFA metabolism on peroxisomal functions and produces ZS-like pathology.

    Full Text Available In the past few years, contributions of molecular biology assays to the investigation of sudden juvenile death have permitted to clarify some of the pathogenetic aspects of sudden arrhythmic death, opening the way to preventive action on victims’ relatives. We reviewed literature on the genetics of sudden juvenile death, and on molecular biology assays performed on autoptic samples. Biological investigation permits the detection of genetic mutations underlying the susceptibility to sudden cardiac death of individuals with rare inherited forms of arrhythmia (Long QT Syndrome, Brugada Syndrome, Lev’s disease etc. through the analysis of critical sequences codifying for ion channel subunits (HERG, KvLQT1, MinK, Mirp1, SCN5A, KCNQ1, KCNH2, KCNE1, KCNE2. The main objective of post-mortem investigation in sudden juvenile death is the detection of treatable monogenic inherited disorders, in order to prevent further deaths among the relatives of the deceased patient.

  1. Kaspar Hauser's recovery and autopsy: a perspective on neurological and sociological requirements for language development. (United States)

    Simon, N


    The feral children literature has frequently been cited for relevance to understanding historical antecedents of autism. Kaspar Hauser, who appeared in Nuremberg, Germany in 1828, is one of these children, raised under conditions of extreme deprivation. His case history and gradual acquisition of language after age 17 years are summarized. There is strong evidence that he was the prince of Baden, abducted from his cradle in 1812. Findings of postmortem examination, conducted after his assassination, are discussed. Hauser's postadolescent recovery of language contradicts the notion of a "critical period" for language development.

Myocarditis according to the Dallas criteria was seen in 25 of 60 cases (42%), and in seven of these cases a probable pathogen (Toxoplasma gondii, cytomegalovirus, fungi......) was demonstrated. Diffuse myocardial fibrosis was seen in 40 of 60 cases (67%) and is considered to be partly due to repair after myocyte necrosis/myocarditis. A myocardium thus weakened might not be able to meet an increase in functional demand, and in 15 of the 39 cases (38%) where an examination of the whole...

    Full Text Available Prion diseases are rare, progressive and fatal neurodegenerative diseases characterized by long incubation period and short clinical course. We present a rare case of Heidenhain variant of Creutzfeldt-Jakob disease, occurring in a 55-year-old lady presenting with dementia, cortical blindness, and myoclonic jerks. She succumbed to the disease within 8 weeks of onset of symptoms. MRI revealed hyperintense signals on T2WI and fluid attenuated inversion recovery (FLAIR images in basal ganglia and fronto-temporal and parietal cortex, sparing thalamus, striate cortex and globus pallidum. Abundant abnormal prion protein deposits (PrP sc were detected in caudate, putamen, thalamus, cingulate and striate cortex, in comparison to frontal and parietal cortex while no deposits were found in globus pallidum. MRI changes did not correlate with degree of spongy change, gliosis or prion protein deposition. The cause for abnormal signal changes in MRI and FLAIR images remains unclear.

  4. Autopsy-confirmed hippocampal-sparing Alzheimer's disease with delusional jealousy as initial manifestation. (United States)

    Fujishiro, Hiroshige; Iritani, Shuji; Hattori, Miho; Sekiguchi, Hirotaka; Matsunaga, Shinji; Habuchi, Chikako; Torii, Youta; Umeda, Kentaro; Ozaki, Norio; Yoshida, Mari; Fujita, Kiyoshi


    Alzheimer's disease (AD) is clinically characterized by gradual onset over years with worsening of cognition. The initial and most prominent cognitive deficit is commonly memory dysfunction. However, a subset of AD cases has less hippocampal atrophy than would be expected relative to the predominance of cortical atrophy. These hippocampal-sparing cases have distinctive clinical features, including the presence of focal cortical clinical syndromes. Given that previous studies have indicated that severe hippocampal atrophy corresponds to prominent loss of episodic memory, it is likely that memory impairment is initially absent in hippocampal-sparing AD cases. Here, we report on a patient with an 8-year history of delusional jealousy with insidious onset who was clinically diagnosed as possible AD and pathologically confirmed to have AD with relatively preserved neurons in the hippocampus. This patient had delusional jealousy with a long pre-dementia stage, which initially was characterized by lack of memory impairment. Head magnetic resonance imaging findings showed preserved hippocampal volume with bilateral enlarged ventricles and mild-to-moderate cortical atrophy. Head single-photon emission computed tomography revealed severely decreased regional cerebral blood flow in the right temporal lobe. The resolution of the delusion was attributed to pharmacotherapy by an acetylcholinesterase inhibitor, suggesting that the occurrence of delusional jealousy was due to the disease process of AD. Although the neural basis of delusional jealousy remains unclear, this hippocampal-sparing AD case may be classified as an atypical presentation of AD.

  7. Exploring vulnerability to suicide in the developmental history of young men: a psychological autopsy study. (United States)

    Rasmussen, Mette L; Haavind, Hanne; Dieserud, Gudrun; Dyregrov, Kari


    This study explores the developmental history of ten young men who completed suicide in the transition to adulthood. The young men, aged 18-30, had no previous history of suicide attempts or treatment in mental health. In-depth interviews with four to eight informants for each suicide were analyzed using Interpretative Phenomenological Analysis. Three developmental issues from early age onwards emerged: (a) unsuccessful in becoming independent; (b) weakened competence to deal with shame; and (c) trapped in anger. The capacity to regulate emotions like shame and anger could make certain men vulnerable to suicide when facing adult challenges and defeats.

  8. Using autopsy brain tissue to study alcohol-related brain damage in the genomic age. (United States)

    Sutherland, Greg T; Sheedy, Donna; Kril, Jillian J


    The New South Wales Tissue Resource Centre at the University of Sydney, Australia, is one of the few human brain banks dedicated to the study of the effects of chronic alcoholism. The bank was affiliated in 1994 as a member of the National Network of Brain Banks and also focuses on schizophrenia and healthy control tissue. Alcohol abuse is a major problem worldwide, manifesting in such conditions as fetal alcohol syndrome, adolescent binge drinking, alcohol dependency, and alcoholic neurodegeneration. The latter is also referred to as alcohol-related brain damage (ARBD). The study of postmortem brain tissue is ideally suited to determining the effects of long-term alcohol abuse, but it also makes an important contribution to understanding pathogenesis across the spectrum of alcohol misuse disorders and potentially other neurodegenerative diseases. Tissue from the bank has contributed to 330 peer-reviewed journal articles including 120 related to alcohol research. Using the results of these articles, this review chronicles advances in alcohol-related brain research since 2003, the so-called genomic age. In particular, it concentrates on transcriptomic approaches to the pathogenesis of ARBD and builds on earlier reviews of structural changes (Harper et al. Prog Neuropsychopharmacol Biol Psychiatry 2003;27:951) and proteomics (Matsumoto et al. Expert Rev Proteomics 2007;4:539).

  10. Central nervous system granulomastous phlebitis with limited extracranial involvement of the heart and lungs: An autopsy case. (United States)

    Mlakar, Jernej; Zorman, Jerneja Videčnik; Matičič, Mojca; Vrabec, Matej; Alibegović, Armin; Popović, Mara


    Primary angiitis of the central nervous system is a rare condition, usually with an insidious onset. There is a wide variety of histological types (granulomatous, lymphocytic or necrotizing vasculitis) and types of vessel involved (arteries, veins or both). Most cases are idiopathic. We describe a first case of idiopathic granulomatous central nervous system phlebitis with additional limited involvement of the heart and lung, exclusively affecting small and medium sized veins in a 22-year-old woman, presenting as a sub acute headache. The reasons for this peculiar limitation of inflammation to the veins and the involvement of the heart and lungs are unknown.

  11. Virtual autopsy using imaging: bridging radiologic and forensic sciences. A review of the Virtopsy and similar projects. (United States)

    Bolliger, Stephan A; Thali, Michael J; Ross, Steffen; Buck, Ursula; Naether, Silvio; Vock, Peter


    The transdisciplinary research project Virtopsy is dedicated to implementing modern imaging techniques into forensic medicine and pathology in order to augment current examination techniques or even to offer alternative methods. Our project relies on three pillars: three-dimensional (3D) surface scanning for the documentation of body surfaces, and both multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) to visualise the internal body. Three-dimensional surface scanning has delivered remarkable results in the past in the 3D documentation of patterned injuries and of objects of forensic interest as well as whole crime scenes. 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 not seen at external examination of the victim. 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, non-invasive or minimally invasive approach will improve forensic medicine in the near future.
