Sample records for Autopsy

  1. The value of neonatal autopsy.

    Hickey, Leah

    2012-01-01

    Neonatal autopsy rates were in decline internationally at the end of the last century. Our objective was to assess the current value of neonatal autopsy in providing additional information to families and healthcare professionals.

  2. Pneumatosis Intestinalis: Autopsy Finding

    Bazmi Shabnam

    2009-10-01

    Full Text Available This is a case of a patient with bowel obstruction , imaging studies were suggestive for pneumatosis intestinalis. Clinically diagnosed as adhesion band and pnematosis intestinalis. She underwent laparatomy, enterolysis, obstructionolysis and enterorrhaphy. The patient developed respiratory distress and expired after 2 days. At autopsy we found gray-brown discoloration in the wall of some part of small bowel and flattening of mucus membrane. Grossly multiple gas-filled cysts were seen at the serosal surface. Microscopic evaluation of small intestine wall showed multiple cysts located in submucosal and serosal layers.

  3. Findings of autopsy imaging

    Described is the outline of autopsy imaging (Ai) by CT, MRI and ultrasonography (US) as the reading of the postmortem images is becoming important for radiologist on site. The present major Ai modality is CT, where the cause of death can be identified in most cases of injuries like that by traffic accident, and of intracranial hemorrhagic lesions. It is difficult for CT alone to determine the cause due to acute heart failure, for which Ai by enhanced CT (2-min heart massage during the intravenous infusion of a contrast agent) has been introduced. CT findings in Ai are varied according to the death cause, anabiotic treatment conducted and postmortem changes. The second item includes the gastrointestinal tract dilation, rib fracture, pneumo- or hemo-thorax, bruise or rupture, and intravascular gas, and the third, the blood hypostasis, which emphasizing the shadow at the gravity-loaded portions in Ai CT. MRI signals vary dependently on the temperature and the inversion time should be shortened to suppress the cerebrospinal signal at Ai of the cold body like that stored in a refrigerator. US can detect clear, macroscopic morphological changes and the portable machine has been in practice at autopsy onsite. As sound speed depends on the temperature in water, Ai US images are obscure relative to living body due to the low temperature. Authors think the problem to identify the cause of death will be mostly solved in Japan when radiological technologists more actively participate in Ai. (K.T.)

  4. Autopsy Tissue Program

    The Autopsy Tissue Program was begun in 1960. To date, tissues on 900 or more persons in 7 geographic regions have been collected and analyzed for plutonium content. The tissues generally consist of lung, liver, kidney, lymph, bone, and gonadal tissue for each individual. The original objective of the program was to determine the level of plutonium in human tissues due solely to fall-out from weapons testing. The baseline thus established was to be used to evaluate future changes. From the first, this program was beset with chemical and statistical difficulties. Many factors whose effects were not recognized and not planned for were found later to be important. Privacy and ethical considerations hindered the gathering of adequate data. Since the chemists were looking for amounts of plutonium very close to background, possible contamination was a very real problem. Widely used chemical techniques introduced a host of statistical problems. The difficulties encountered touch on areas common to large data sets, unusual outlier detection methods, minimum detection limits, problems with Aliquot sizes, and time-trends in the data. The conclusions point out areas to which the biologists will have to devote much more careful attention than was believed

  5. Congenital hyperthyroidism: autopsy report

    Lima Marcus Aurelho de

    1999-01-01

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

  7. Autopsy experience with a radioactive cadaver

    A patient who received a 200-mCi dose of 131I for widespread carcinoma died 10 days after treatment with 50 mCi remaining in the cadaver. An autopsy was required. The radiation levels were sufficiently high that personnel radiation protection was needed. An autopsy procedure was designed that prevented ingestion of radioactivity by the pathologist and his assistants, prevented excessive exposure of any involved personnel, and prevented contamination of the autopsy room or other hospital space.

  9. Judicial autopsy of radiation accidents

    This paper discusses issues regarding the judicial autopsy of radiation accidents. In the litigation which follows a radiation accident, a claimant calls on the legal system to adjudicate a dispute. Scientific questions are thrust upon the court. The legal system (through attorneys for the parties) then invites scientists to assist the court in resolving such questions. The invitation, however, does not allow the scientist to bring along his full kit. Experimentation, such as repeating the accident with dosimeters to gather more accurate data, is generally not allowed. Also, the scientist must give up his practice of choosing which questions he will pursue

  10. [Cervical fractures in autopsy records].

    Pankowski, Rafa?; Wilmanowska, Anita; Gos, Tomasz; Smoczy?ski, Andrzej

    2003-01-01

    We reviewed the autopsy records of 1872 cases of death because of politrauma, gunshot wounds and suicidal hanging. The analysis included causes and frequency of cervical spine fractures, their most common localisation, architecture of bone destruction and their influence on cervical cord. The most common cause of cervical spine injury was motor vehicle accidents. We examined 82 specimens with traumatic fractures of cervical spine obtained from accident victims. About half of the injuries occurred in upper cervical spine. The most common fracture localisation was C2 with dens fracture as the most frequent injury. The most common spinal cord lesion was complete rupture mainly at the upper cervical spine level. PMID:14564791

    A three (3) year prospective macroscopic autopsy study of cardiomegaly, heart size ≥400grams, was conducted at the Korle Bu Teaching Hospital Mortuary between 1st January 1998 and 31st December 2000. Cardiomegaly constituted 12.2% of the autopsy series over the 3-year period. The causes of cardiomegaly were essential hypertension in 55% of cases and hypertension of renal origin in 23.4% of cases. Cardiomyopathies, cor pulmonale, chronic rheumatic heart diseases, ischaemic heart diseases, chro...

  13. Low perinatal autopsy rate in Malaysia: time for a change.

    Tan, Geok Chin; Hayati, Abdul Rahman; Khong, Teck Yee

    2010-01-01

    Our objectives were to determine the perinatal autopsy rate in a tertiary hospital in Malaysia and to quantify the value of the perinatal autopsy. All stillbirths, miscarriages, therapeutic abortions, and neonatal deaths between January 1, 2004, and August 31, 2009, were identified from the archives. The autopsy findings were compared with the clinical diagnoses. The autopsy reports were also reviewed to determine if it would be possible to improve the quality of the autopsies. There were 807 perinatal deaths, of which 36 (4.5%) included an autopsy. There were ethnic differences in the rate of autopsy, with the lowest rate among the Malays. The autopsy provided the diagnosis, changed the clinical diagnosis, or revealed additional findings in 58.3% of cases. Ancillary testing, such as microbiology, chromosomal analysis, and biochemistry, could improve the quality of the autopsy. This study provides further data on the perinatal autopsy rate from an emerging and developing country. It reaffirms the value of the perinatal autopsy. Attempts must be made to improve on the low autopsy rate while recognizing that the performance of autopsies can be enhanced through the use of ancillary testing. PMID:20367214

  16. Adult Hirschsprung's disease diagnosed during forensic autopsy.

    Chatelain, Denis; Manaouil, Cécile; Marc, Bernard; Ricard, Jannick; Brevet, Marie; Montpellier, Dominique; Defouilloy, Christian; Jardé, Olivier

    2006-09-01

    We report a case of fatal Hirschsprung's disease (HD) discovered at autopsy. A 20-year-old man collapsed at home. Emergency medical personnel found him in cardiac arrest and all resuscitative efforts failed. He had a past history of chronic constipation since infancy. Forensic autopsy revealed a megacolon full of gas and stools. Microscopic examination showed absence of ganglion cells in a short segment of the rectum and enterocolitis in the left and transverse colon. HD is rarely described in adults. In many cases, patients complained of constipation since infancy but the affection remained misdiagnosed. The relative good tolerance of the disease is usually due to a short aganglionic bowel segment. Enterocolitis is a frequent and severe complication of HD in children but is rarely described in adults. This case suggests the importance of HD diagnosis in childhood in order to avoid fatal complications with forensic consequences. PMID:17018101

  18. Can postmortem fetal MR imaging replace autopsy?

    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

  1. Autopsy findings in small cell lung cancer

    The objective of this study was to assess the pattern of autopsy in 174 small lung cancer patients treated between 1971 and 1991 at seven Polish medical centres. Eighty nine autopsied patients were previously treated with different chemotherapy regimens including 32 patients who also received chest irradiation, 74 received only supportive care and for 11 patients the data on treatment were not available. The age range at diagnosis was 28-81 years (median 57); there were 39 females (22%) and 135 males (78%). Seventy two patients had limited disease at the time of diagnosis, 86 - extensive disease and in 16 the disease extent was not determined. The primary tumor and/or metastases in regional lymph nodes were present in 157 autopsies (90%). There was a significant difference in the rate of locoregional disease found at autopsy in patients given chemotherapy and in those who received only supportive care (85% and 100%, respectively; p = 0.01). Chest radiation therapy given in limited as an adjunct to chemotherapy did not decrease the rate of persistent locoregional disease (primary tumor in the chest was found in 92% of irradiated and in 96% of nonirradiated patients). Locoregional tumor deposit only was found in 28 (16%). Distant metastases were distributed in 143 patients (82%) and were found in 25 different locations, most frequently in liver (49%), supra-renal glands (25%), peripheral lymph nodes (21%), kidneys (18%), brain (17%) and pancreas (12%). In 3 patients no tumor foci were found. The number of organs involved varied between 0 and 10 (median 3). The number of involved organs was not dependent on the disease extent at the time of diagnosis and on the type of treatment. (author)

    Full Text Available Severe malaria, caused by Plasmodium falciparum infection, has a high mortality rate and is the main cause of death in malaria. Since clinical autopsy is unpopular in Indonesia, autopsy examination in malaria cases is rarely done. We reported a forty three year old woman from non endemic area that was dead because of severe malaria. Diagnosis was concluded from autopsy, histopathology, and toxicology.

  3. Autopsy findings of fatal cryptogenic organizing pneumonia.

    Terada, Tadashi

    2013-01-01

    Autopsy cases of cryptogenic organizing pneumonia (COP) have been rarely reported. A 73-year-old Japanese man consulted to a hospital because of flu-like sickness. He was diagnosed as pneumonia, and treated by antibiotics. He was referred to our hospital for further treatment. Chest X-P showed pneumonia involving the whole lungs. Blood laboratory test showed leukocytosis, increased CRP, and decreased PaO2. Despite of steroid therapy, he showed a downhill course and died one month after the first manifestation. The clinical diagnosis was acute pneumonia or ARDS. At autopsy, the both lungs were voluminous. The weight of lungs was 1050 g in the left lung and 1300 g in the right lung. The both lungs were entirely affected. The lungs were hard and little air was recognized. Microscopically, almost all alveolar spaces contained Masson's bodies. Bronchiolitis obliterans was not recognized. The alveolar walls were not affected. The Masson's bodies showed collagenization with lymphocytic infiltration. Hyalinization of Masson's bodies with little inflammatory infiltration was frequently seen. Cartilagenous metaplasia and ossification of Masson's bodies were seen in some places. The pulmonary arteries were affected by fibrosis, and occasionally showed thrombosis. The pathological diagnosis was COP. The heart weighted 500 g, and showed right ventricular hypertrophy (cor pulmonale). Other pathologic changes were pleural effusion (left, 800 ml: right, 1200 ml), acute liver congestion, prostatic hypertrophy, colon adenoma, and hypercellular bone marrow. The cause of death was respiratory failure due to COP and pleural effusion. In conclusion, the author reported an autopsy case of fatal COP. PMID:23696931

  5. Management and autopsy of a radioactive cadaver

    A 69 year old male was treated with an ablative dose of 3.7GBq (10 mCi) of I131 for carcinoma of the thyroid and died 10 days after administration. The requirement for an autopsy and the level of radiation still present in the body necessitated the intervention of radiation safety personnel to minimise support staff radiation exposure and area contamination. Preventative measures were taken in accordance with the ALARA principle and a detailed procedure is presented as a suggested model for any future occurrence

  6. Radiographic investigations during medico-legal autopsies

    During the last 13 years (1968-1980), 427 radiographic examinations were carried out during the course of medico-legal autopsies at the Institute of Forensic Medicine at the Free University of Berlin. Important problems were the demonstration of retained foreign bodies resulting from shooting, stabbing or blunt trauma, bone injuries, identification, and the question of life in neonates. An historical survey is given and 12 cases with special forensic problems are illustrated and discussed, and further means of investigations are described. (orig.)

  7. Autopsy issues in German Federal Republic transplantation legislation until 1997.

    Schweikardt, Christoph

    2014-01-01

    This article analyzes the relevance of autopsy issues for German Federal Republic transplantation legislation until 1997 against the background of legal traditions and the distribution of constitutional legislative powers. It is based on Federal Ministry of Justice records and German Parliament documents on transplantation legislation. Transplantation and autopsy legislation started with close ties in the 1970s. Viewing transplantation legislation as relevant for future autopsy regulation contributed to the decision to stall transplantation legislation, because the interests of the federal government and the medical profession converged to avoid subsequent restrictions on the practice of conducting autopsies and procuring tissues for transplantation. Sublegal norms were insufficient for the prosecution of the organ trade and area-wide transplantation regulation after the reunification of Germany. In contrast to autopsy issues, legislative power for transplantation issues was extended to the federal level by an amendment to the constitution, allowing decision making for Germany as a whole.

    Malaria inflicts a huge health care burden in terms of mortality and morbidity worldwide. There has been evidence in the literature where many unexpected/unexplained deaths turned out to be related to malaria on autopsy. The aim of this study is to review autopsy diagnosed malaria related deaths in the literature with due stress to its biologic and forensic aspects. A meticulous literature search was performed for "sudden malaria death", "malaria death postmortem diagnosis" and "unexplained death malaria" across PubMed, SCOPUS, Cochrane Database of Systematic Reviews, Allied and Complementary Medicine, British Nursing Index, CINAHL, EMBASE, Ovid-MEDLINE and Google Scholar. All the literature was thoroughly reviewed and analyzed with reference to the type of study, location, travel history, age, gender, circumstance of death, method of diagnosis, species involved, chemoprophylaxis usage and take home message from the particular study. Plasmodium falciparum was responsible in most of the cases. The symptoms mimicked influenza in most of the case reports. Travel to endemic areas was common to most of the victims. The travelers were from all over the world including USA, France, Switzerland, Spain, Portugal, Germany and Asia (China and Japan). Vascular congestion with the presence of malarial pigment laden RBCs in capillaries of various organs was the major histopathology finding. Such lesions were found in the brains of all subjects (100%), liver of 78% of the cases, spleen in 67%, lungs in 56% and myocardium in 43% of the cases. Peripheral smear and rapid diagnostic test was of great aid to the autopsy in many cases. PCR was used for diagnosis as well as exclusion of possibility of co-infection with other species in case of Plasmodium knowlesi related death. The postmortem and histopathology findings in this case were similar to P. falciparum except for the fact that brain sections were negative for intracellular adhesion molecule-1. Chemoprophylaxis was not taken by the victims except for two in whom history of chloroquine based chemoprophylaxis was mentioned. Given the worldwide prevalence of the disease, increasing international travel and rapidly developing drug resistance, malaria will continue to be an important disease and should be considered in all cases of unexpected deaths particularly in malaria endemic regions or in presence of travel history to endemic regions.

  9. Value of postmortem computed tomography in comparison to autopsy; Prospektive Untersuchung zur Wertigkeit der postmortalen Computertomographie im Vergleich zur Autopsie

    Paperno, S.; Krug, B.; Lackner, L. [Klinik und Poliklinik fuer Radiologische Diagnostik, Univ. zu Koeln (Germany); Riepert, T.; Rothschild, M.A.; Schultes, A.; Staak, M. [Inst. fuer Rechtsmedizin des Klinikums der Univ. zu Koeln (Germany)

    2005-01-01

    Purpose: to assess the diagnostic value of postmortem computed tomography (CT) in comparison to autopsy. Materials and methods: twenty-seven cadavers were examined by sequential cranial CT and helical CT through the neck, thorax and abdomen and subsequently underwent an autopsy with histomorphologic examination of the pathologic specimens. The findings of CT, autopsy and histology were registered and compared by three radiologists and one specialist for forensic medicine, using a data entry form. Results: in 19 of 27 cases, the findings explaining the cause of death were concordant for CT and autopsy. Intracranial, intraspinal and intracardiac gas accumulations (n = 12) were registered by CT alone. The detection of skull fractures was equal for both methods (n = 3). CT showed diagnostic problems in the assessment of pneumonic infiltrations (n = 16) and pulmonary edema (n = 21). Conclusion: CT is a useful and complementary method to autopsy. (orig.)

  10. SIRENOMELIA: A DETAILED FETAL AUTOPSY STUDY

    Parimala Sirikonda

    2015-12-01

    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.

    2009-01-01

    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.

    2012-01-01

    Sudden cardiac death (SCD) is one of the most common causes of death in developed countries, with most SCDs involving the elderly, and structural heart disease evident at autopsy. Each year, however, thousands of sudden deaths involving individuals younger than 35 years of age remain unexplained after a comprehensive medicolegal investigation that includes an autopsy. In fact, several epidemiologic studies have estimated that at least 3% and up to 53% of sudden deaths involving previously hea...

  13. FETAL AUTOPSY STUDY OVER A TWO YEAR PERIOD

    Shailaja

    2015-02-01

    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. Genetic studies were done in 6 cases (26.08 % in the form of parental kary otyping and cord blood could be tested in only one case. CONCLUSIONS: There is a good correlation between prenatal ultrasound scanning and autopsy findings. However , functional heart defects , and minute ventricular septal defects cannot be identified on autopsy due to the small size of the organs. At the same time autopsy can demonstrate more accurately congenital malformations and unsuspected cord abnormalities. More awareness is required on the part of treating clinician s as to the appropriate sample collection , its timely transport to the laboratory in order to facilitate genetic testing.

    We have reviewed the pathological reports of adult necropsies performed in Amiens hospital during the 1975-2005 period. 1,639 autopsies were performed in 1,049 men and 590 women. We distinguished three periods: 1975-1987 (period 1) with a high number of autopsies (86/year), 1988-1996 (period 2) with a huge decrease of autopsies performed (43/year) and 1997-2005 (period 3) with few autopsies performed (14/year). Patients were younger during period 3, 38% were less than 50 years old versus 26% and 29% during periods 1 and 2. The sex ratio M/F increased during period 3 (2.7 versus 1.7 and 1.9 during periods 1 and 2). Period 3 showed an increase of major diagnoses discovered during autopsies (36% versus 28% of autopsies performed during periods 1 and 2) and showed an increase of autopsies performed after iatrogenic events (20% versus 12% and 13% of autopsies of periods 1 and 2). Period 3 showed an increase of the delay between the death of patients and autopsy and a decrease of the delay of transmission of pathological reports. 2% of autopsies were never answered by the pathologists. In conclusion, our study confirms the major decline of autopsies during the last 30 years. Patients autopsied are currently young men and the autopsies are more frequently performed in potential forensic circumstances. Selection biases explain that major diagnoses are more frequently found at autopsies nowadays than 30 years ago. PMID:18185448

    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.

  16. Neuropathologic findings after organ transplantation. An autopsy study.

    Schwechheimer, K; Hashemian, A

    1995-05-01

    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.

    2009-09-01

    Body stalk anomaly (BSA) is a sporadic polymalformative syndrome incompatible with extrauterine life. In utero detection of BSA by two-dimensional and three-dimensional ultrasonography and magnetic resonance imaging has been well documented. We herein describe a case of body stalk anomaly diagnosed at autopsy. The fetus had a large anterior midline abdominal wall defect with eventration of the visceral organs into the amnio-peritoneal sac and a completely absent umbilical cord. The associated anomalies included club foot, absent diaphragm, genitourinary, and gastrointestinal defects. The observed congenital anomalies supported the theory of embryonic dysgenesis as the etiologic factor. One of the major objectives in the performance of fetal autopsy is to be able to detect abnormalities that can have implications in future pregnancies. Despite the negligible familial recurrence rate of the broad spectrum of anomalies associated with this abdominal wall defect, the present case of fetal autopsy indeed delights to serve the living.

  18. Clinical diagnosis versus autopsy findings in polytrauma fatalities

    Fakler Johannes K

    2010-10-01

    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.

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

    Cristiano C. Oliveira

    2015-10-01

    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.

    Mesenteric venous thrombosis is a rare disorder with a high mortality rate. Since patients remain asymptomatic, diagnosis of the disease is difficult. Diagnosis can be mainly made with either laparotomy or autopsy. Many factors are considered in the etiology of mesenteric venous thrombosis. Liver cirrhosis and chronic pyelonephritis, which we detected in the autopsy and histologic examination of our case, are considered as two of the factors. In our study, it was aimed to present a case with near-total intestinal necrosis caused by portal vein thrombosis which spread to the lineal vein, pancreatic vein and to the branches of superior mesenteric veins.

    2016-03-01

    We had a forensic autopsy case that required additive pathological examination for the asbestos-related lung disease compensatory application afterwards. A man in his sixties with a history of occupational asbestos inhalation who had neither visited a hospital nor received a physical examination received forensic autopsy because of his death from unknown cause. An inmate said, "He developed cough and dyspnea, and died in the progression of the symptoms." The autopsy revealed widespread pleural plaques on both sides of the parietal pleura and multiple tumors in both sides of the lungs. The cause of death was diagnosed as lung cancer. Additional pathological examination was asked by his family to certify that he had suffered from asbestos-related lung disease in order to apply to the Asbestos-related Damage Relief Law. The Japanese criteria of the compensation law of asbestos-related lung cancer is the detection of more than 5,000 asbestos bodies per gram of dry lung tissue, while his number of asbestos bodies was 4,860. Asbestos bodies were reported to be accumulated in the distal lung parenchyma with no pathological changes. The present lung samples were collected from proximal section around the tumor, which might have made the number of asbestos bodies less than the criteria. Both the number of patients suffering from asbestos-related lung disease and the number of forensic autopsy cases have increased in Japan. Collecting lung samples from the appropriate lung section is essential and should be noted when the lung cancer is suspected at forensic autopsy in order to apply for asbestos-related lung disease compensation.

  6. [Applications and advantages of a multimedia system for autopsies ].

    Gualco, M; Benzi, D; Fulcheri, E

    2001-10-01

    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 each organ, together with external and cut-surface features. A third section allows the examiner to report other observations not requested previously, while a final section is also provided for the epicrisis and for the formulation of the final diagnosis, the same as that reported in the first form. The database is coupled with an interactive system for collecting voice comments, thereby replacing the need for tape-recorders in the autopsy room. The user can recall a dictation window, dictate a text, check spelling and insert additional text. The database is also coupled to an image acquisition system, on the assumption that moving images allow a more faithful documentation of reality. Therefore, all rooms in which autopsies are carried out on fetuses or neonates have been equipped with a fixed camera linked to a monitor and a video-recorder. A PCB, used for image digitalization, recognizes up to 16,000,000 different colors. Guided by dedicated software, image files are transferred to a computer and then saved with the autoptic report. The database can be consulted and queried in two principle ways: by key words in the contents or main disease descriptions, or by individual words or phrases contained within the complete text of the reports. The present database system for autopsy reporting has proved itself useful in a pathological anatomy service. The combined presence of images and texts renders the system useful also as a research tool. By linking to a Web site dedicated to pathologic anatomy, it will be possible to display online rare cases involving diagnostic difficulties. The system offers great advantages for present and retrospective diagnostics, as well as for research and education purposes. PMID:11725353

  7. The medical autopsy as quality assurance tool in clinical medicine: dreams and realities.

    van den Tweel, Jan G; Wittekind, Christian

    2016-01-01

    The purpose of medical autopsy has changed to issues of quality assurance today. In addition, autopsies are considered valuable in medical education, e.g., delivering cases for problem-based learning for students. Many studies underscore the need for autopsies also in the era of technical progress emphasizing the continuing discrepancies between antemortem and post mortem diagnoses. Despite these important tasks, we face a decline of autopsy for several reasons with complex interactions. The role of all persons involved in this decline is evaluated and suggestions for changes are proposed. Last but not least, the future of the autopsy is in the hands of pathology itself.

  8. The Homicide-Suicide Phenomenon: Findings of Psychological Autopsies.

    Knoll, James L; Hatters-Friedman, Susan

    2015-09-01

    Homicide-suicide represents a single episode of violence which may decimate an entire family. This study aimed to further describe motives and context of these tragedies. Psychological autopsies were completed for 18 homicide-suicide cases in Dallas, Texas. This included postevent interviews with surviving family members and review of police and coroner records. Two-thirds of perpetrators had made either verbal or written threats prior to the homicide-suicide. A simplified typology describing victim-perpetrator relationship and motive type is suggested for future studies and clinical ease. Two-thirds of perpetrators fell into the category of Intimate-Possessive, most of whom were depressed men who were abusing substances and undergoing separation. Additional categories included Intimate-Ailing, Filial-Revenge, Familial-Psychotic, and Friend-Psychotic. Further, implications from this psychological autopsy study regarding risk assessment include use of collateral interviews regarding threats and past violence. PMID:26259152

    Cancer of unknown primary is associated with unknown biology and dismal prognosis. The most common primary sites of cancer of unknown primary were usually the lungs in autopsy studies, and intrahepatic cholangiocarcinoma is rare. We describe the case of a 57-year-old male patient with systemic lymph node metastasis. Imaging examination failed to reveal primary cancer; however, immunostaining of cytokeratins 7, 19, and 20 of a metastatic axillary lymph node suggested a pancreaticobiliary cancer as a primary lesion. He died of liver abscess and sepsis, and then, autopsy indicated occult intrahepatic cholangiocarcinoma. We discuss the clinical course of this rare cholangiocarcinoma including the diagnostic procedure and also present a review of the English literature regarding patients with cancer of unknown primary.

    2006-01-01

    A retrospective analysis of pediatric autopsies in the past 18 years was done with the aim of studying the histomorphology of renal dysplasia. Renal dysplasia comprised 150 (3.66%) of the 4,099 pediatric autopsies from 20 weeks of gestation to 1 year of life. Primitive ducts with the fibromuscular collar, the sine qua non of renal dysplasia, was seen in all cases. Lobar disorganization and cysts were seen in all cases except for the 7 cases of hypodysplasia. Other elements were seen in varying proportions: cartilage in 33.7%, bone in 1.08%, thickening of basement membrane of the primitive ducts in 64.13%, extramedullary hematopoiesis in 98.9%, nerve twigs in 72.8%, and nodular renal blastema in 2.17% cases. In unilateral multicystic dysplasia/renal agenesis, the contralateral kidney showed abnormalities in 44.45% and 47.37% of cases, respectively. PMID:16908457

    Durão, Carlos; Carpinteiro, Dina; Pedrosa, Frederico; Machado, Marcos P; Cunha, Eugénia

    2016-05-01

    Enlarged parietal foramina (EPF) are a quite rare developmental defect of the parietal bone which has to be distinguished from the normal small parietal foramina. We report a forensic case of an individual found in an advanced state of putrefaction in his own house with an undetermined cause of death. No evidence of trauma was observed, and the toxicological exam was negative. The victim was a 40-year-old man with a history of epilepsy. The large biparietal foramina, a rare anatomical variation and unusual autopsy finding, were observed at autopsy. The recognition of anatomical variations is important to avoid false interpretations and conclusions and has a significant potential as an identity factor, thus contributing to positive identification.

  12. Radioisotopes in tissues of patients studied at autopsy

    Following 67Ga scanning, a high dose of radioactivity was found in a gastric adenocarcinoma at autopsy. The amount of radioactivity in the adrenal glands, spleen, and bone marrow was also high. It was estimated that the pathologist received a whole-body dose of 100 to 200 mR which is considered to be an unacceptable risk. It is emphasized that medical personnel should be aware of patients who have had recent radionuclide scans

    2005-09-01

    Studies of dose-response relationships between respiratory outcomes at autopsy and coal dust exposure are limited. The Pathology Automation System (PATHAUT) database of South African miners, is one of the largest autopsy databases of occupational lung disease. This study described the prevalence of respiratory outcomes among South African coal miners at autopsy, and determined whether dose response relationships existed between emphysema and exposure. Autopsies conducted from 1975 to 1997 on coal miners with exclusive coal mining exposure and having exposure duration information (n = 3,167) were analyzed from PATHAUT Logistic regression was used to determine relationships between exposure and outcomes, controlling for race, smoking and age on a subset for whom smoking history was available (n = 725). The prevalence of silicosis, tuberculosis (TB), coal workers' pneumoconiosis (CWP), and moderate and marked emphysema were 10.7%, 5.2%, 7.3%, and 64%, respectively. All diseases, except TB, were associated with exposure duration. Black miners had 8.3 and 1.2 fold greater risks for TB and CWP, respectively, than white miners. White miners had an increased risk of 1.4 and 5.4 for silicosis and moderate to marked emphysema, respectively. In models unadjusted for age, and including smoking, moderate to marked emphysema was strongly associated with exposure duration (OR = 3.4; 95% CI = 1.9-5.9 for highest tercile of exposure duration). Exposure-related risk estimates were reduced when age was introduced into the model. However age and duration of exposure were highly correlated, = 0. 68) suggesting a dilution of the exposure effect by age. There were significant dose related associations of disease, including emphysema, with coal dust exposure.

    1985-01-01

    Forty-six consecutive autopsies performed in 1 year on patients who died in a 120-bed urban community hospital were analysed with respect to clinical-pathological correlation. The mean age of the patients was 71 years. Errors in clinical diagnosis were assigned to one of four classes: class I, a missed major diagnosis, the detection of which before death would probably have changed management and resulted in longer survival or possible cure; class II, a major missed diagnosis that, if detecte...

  18. The Abbreviated Injury Scale: application to autopsy data.

    Adams, V I; Carrubba, C

    1998-09-01

    Twenty autopsy reports, comprising 1 fall, 1 cutting, 1 burn, 1 drowning, 1 strangulation, 3 gunshot wound, and 13 traffic fatalities, were scored by the Abbreviated Injury Scale (AIS) and the Injury Severity Score (ISS). The codes were adequate for wounds of skin and long bones, and for most wounds of viscera. The autopsy descriptions were more detailed than the coding criteria for craniocerebral, cervicovertebral and muscular trauma, and less detailed for thoracoabdominal visceral, and long bone trauma. Lung contusions and rib fractures received scores that seemed unduly high, possibly reflecting the greater sensitivity of autopsy diagnosis over clinical diagnosis for these lesions. Complete hinge fractures of the skull base scored 4 (severe), which does not reflect the almost universally lethal nature of the accompanying cerebral concussion, which was itself not codeable. AIS scores were low and did not seem to reflect the lethal outcome when the lethal mechanism was purely physiologic and without a striking morphologic derangement, as in instances of cerebral or cardiac concussion, compression of the neck, occlusive airway hemorrhage, and visceral herniation into an adjacent body cavity. The scores were similarly low when therapy was delayed or adverse. Low AIS and ISS scores in a fatality from blunt or penetrating trauma may be useful retrospective clues to the presence of purely physiologic death mechanisms or therapeutic problems. PMID:9760090

    2015-01-01

    Full Text Available Introduction. The risk of suicide among war veterans is a controversial issue, where findings so far have been contradictory. Objective. This study focusses on suicide in Serbian veterans from the wars in former Yugoslavia in the 1990s in order to create appropriate preventive measures and reduce the number of these fatal cases. Methods. The autopsy protocols of all 44 suicides committed by war veterans in the Belgrade District population over a period between 1992 and 2000 were investigated. Data were obtained from autopsy records, results of toxicological investigations and psychological autopsy protocols. Results. Symptoms of posttraumatic stress disorder were present in 27.3%, major depression in 9.1% and schizophrenia in 6.8% of veterans. The majority of suicides (84.1% were committed by recruits in the Yugoslav National Army, spending between three and eight months in the zone of war operations. Six committed suicide during the first 30 days after their war activities, while the majority of suicides occurred between five and six years after combat. The most frequent manner of suicide was the use of handguns (56.8% and bombs (18.2%. Conclusion. The results of this research may give useful information about the individuals with the highest suicidal risk in order to alleviate the consequences of war psychotraumas in veterans and prevent their growth into a permanent handicap or suicide.

    South Africa has one of the largest miner autopsy databases, PATHAUT dating back to 1925. The diagnoses recorded on this database have never been evaluated for coal miners. The objective was to determine the validity of the autopsy diagnoses for coal workers, specifically bronchitis, silicosis, tuberculosis, coal workers' pneumoconiosis and emphysema, from 1975 to 1997. Three pathologists experienced in miner respiratory pathology conducted the review. They were blinded to employment and medical histories as well as to previous pathological diagnoses on PATHAUT and reviewed 28 coal miners with mixed mining exposures, and 31 cases with exclusive coal mine exposure-all selected randomly. The reviewers' independent and consensus diagnoses were compared to PATHAUT. An additional 31 cases with available whole mount sections were reviewed for the diagnosis of emphysema. Kappa statistics were used to determine degrees of agreement among reviewers and between reviewers and PATHAUT. This, the first systematic review of PATHAUT autopsy diagnoses made on coal workers, showed that PATHAUT can be used with confidence to establish a diagnosis of moderate to severe grades of coal workers' pneumoconiosis. The grade of emphysema recorded on PATHAUT could be used for epidemiological purposes, when whole mount sections have been prepared.

    BACKGROUND: Information on causes of death in HIV-infected patients in Sub-Saharan Africa is mainly derived from observational cohort and verbal autopsy studies. Autopsy is the gold standard to ascertain cause of death. We conducted an autopsy study to describe and compare the clinical and autopsy causes of death and contributory findings in hospitalized HIV-infected and HIV-uninfected patients in Uganda. METHODS: Between May and September 2009 a complete autopsy was performed on patients tha...

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

    2015-05-01

    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 neonatal deaths. In a total of 46 fetuses, there were 13 male and 33 female babies. On external examination of 46 fetal and Neonatal (perinatal deaths, 8 (17.39% babies showed congenital malformation. On internal examination of the 46 fetal and Neonatal (perinatal deaths, 4 babies showed internal congenital anomalies. A total of 46 anatomical and histopathologic examinations were done among fetal and neonatal (perinatal deaths. Out of 13 autopsies on male babies, 2 had congenital malformation and 33 autopsies on female babies, 7 had congenital malformations. Congenital anomalies were commonest in the birth weight group of 1000-1500 grams accounting for 9 cases. Malformations of central nervous system (33.33% were most common followed by musculoskeletal system (16.66%, genitourinary and respiratory system (8.33% respectively. Conclusion: Most number of perinatal deaths occurred in low birth weight and preterm babies. Study of malformations greatly helpful in genetic counseling and prenatal diagnosis in successive pregnancies. [Int J Res Med Sci 2015; 3(5.000: 1114-1121

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

    Kaar, T K

    2012-02-03

    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.

  6. CAUSES OF DEATH IN NEWBORN INFANTS ACCORDING TO AUTOPSY FINDINGS

    Gh.- R. Walizadeh

    1987-12-01

    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.

  7. Primary diffuse leptomeningeal gliomatosis: An autopsy case report

    Shaik Afshan Jabeen

    2014-01-01

    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.

    Oertel, Reinhard; Arenz, Norman; Zeitz, Sten Gunnar; Pietsch, Jörg

    2015-08-01

    With screening methods in the legal medicine drugs were often detected in autopsy material. In this study the antiarrhythmic and the local anesthetic drug lidocaine could be proved in fifty-one cases and determined in different autopsy materials. For the first time the comparison of so many distribution patterns of lidocaine in human compartments was possible. A liquid-liquid extraction procedure, a standard addition method and LC/MS/MS were used for analytics. The measured concentrations in blood were in the therapeutic range or lower. The time between lidocaine application and death was given in twenty-nine cases. These data were very helpful to estimate and interpret the distribution process of lidocaine between application and death. This time exerted a crucial influence on the distribution of lidocaine in the compartments. Most of the intravenous applicated lidocaine was found in heart blood after a very short time of distribution. Afterwards the highest concentrations were measured in brain. Later the highest concentration was found in the kidney samples or in urine. If the time between lidocaine application and death is known, the results of this study can be used to deepen the knowledge of its pharmacokinetics. If this time is unknown, the circumstances and the causes of death can be better explained. PMID:25619956

    2015-06-01

    Zolpidem is a widely used ultrashort-acting non-benzodiazepine in clinical practice; compared with benzodiazepines, it does not have side effects such as daytime hangover, rebound insomnia, and development of tolerance. We report an autopsy case of abnormal behaviour induced by zolpidem. A man in his 60's had suffered from postherpetic neuralgia about 2 months ago and had been prescribed zolpidem for insomnia. According to his family, he had no memory of his actions such as striking a wall, taking his futon outside, and eating 5 times a day after he took zolpidem. Because his postherpetic neuralgia did not improve, he was hospitalized and treated with an epidural block. During hospitalization, he took off his clothes, removed the epidural block catheter by himself, and slept on others' beds. He disappeared from the hospital one day; the next day, he was found dead in a narrow water storage tank 10 km away from the hospital. He was thought to have driven a car by himself to reach the place. Forensic autopsy revealed that the cause of death was drowning. Zolpidem and several other drugs were detected by toxicological analysis of his blood; the concentrations of these drugs were within therapeutic range. There are several reports about somnambulism induced by zolpidem such as sleepwalking, sleep driving, and eating. Considering the strange episodes following zolpidem administration, his behaviour on the day of his death was considered abnormal behaviour induced by zolpidem. PMID:26306385

    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. PMID:26137593

  11. The importance of autopsy examination in major disasters.

    Mason, J K

    1984-01-01

    It is appreciated that there are national and jurisdictional variations in regard to post-mortem dissections following accidental death. The purpose of this paper is to plead that, since there will be nationals of many states involved in an aircraft disaster, there should be a uniform system of forensic investigation on a world wide basis. The justification for this recommendation is illustrated through the investigation of accident causes and through the solution of the many problems relating to the settlement of probate which arise in accidental death. The causes of accidents which may be discovered by autopsy include crew incapacitation and criminality of all types. The emergency status may also be revealed and the type of accident, particularly whether in a controlled or uncontrolled phase, may become clear. The medico-legal problems to be resolved include those concerning payment of insurance policies, including the degree of life expectancy, and especially the disposal of estates when members of a family apparently die together. The resulting payments to beneficiaries may be quite different depending on the quality of the autopsy. These investigations are complementary to, and do not interfere with, the identification process but they are time consuming and expensive. PMID:6517499

    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.

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

    Miguel Angel Serra Valdés

    2013-12-01

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

  14. Autopsy practice in forensic pathology - evidence-based or experience-based? a review of autopsies performed on victims of traumatic asphyxia in a mass disaster.

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

    2014-02-01

    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.

  15. Differences between postmortem computed tomography and conventional autopsy in a stabbing murder case

    Talita Zerbini

    2014-12-01

    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.

    Creutzfeldt-Jakob disease (DJD) is one of the transmissible spongiform encephalopathies, which is mediated by what has been known as 'prion'. It is a rare and fatal progressive neurodegenerative disease that affects the middle and old aged. There are a number of subtypes of CJD, one of which is the sporadic type characterized by rapidly progressing clinical symptoms, including progressive dementia, myoclonic jerk, and pyramidal or extrapyramidal syndrome. Patients usually end up dying within 1 to 2 years of contacting the disease. We report an autopsy-proven case of sporadic CJD with clinical symptoms that progressed within several days, along with dramatic changes on diffusion weighted magnetic resonance images.

    1998-11-13

    Autopsy kidney specimens from 24 children with kwashiorkor and 21 with other miscellaneous diseases, at the Obafemi Awolowo Teaching Hospital Complex, Ile-Ife, Nigeria, were analyzed for the presence of aflatoxins using high-performance liquid chromatography. Aflatoxins were detected in 14 children who died of kwashiorkor and in 13 of those who died from miscellaneous diseases. Aflatoxicol was detected in 10 specimens, 7 of which had severe gastroenteritis. Seven kidney specimens demonstrated the presence of more than one type of aflatoxin; four of these were kidneys of patients with kwashiorkor and the remaining three died from renal failure. No difference was found between the frequency of detection, type of aflatoxin detected, or mean concentrations of total aflatoxins in the kidney specimens of the kwashiorkor children when compared to the kidney specimens of children who died from miscellaneous diseases. These findings demonstrate that aflatoxins can be detected in the kidneys of children exposed to aflatoxins. PMID:9829555

In this paper, we present an autopsy case of combined zygomycosis and aspergillosis. A female in her 70s on chronic hemodialysis was admitted to a hospital suffering bloody sputum, dyspnea, and fever, probably due to perinuclear anti-neutrophil cytoplasmic antibody-related vasculitis. Antibiotics were administered and immunosuppressive therapy was started, resulting in an improvement in her condition. Pneumonia later developed, followed by pulmonary bleeding and intractable pneumothorax from which she ultimately died. On autopsy, the upper lobe of the left lung was found to have hemorrhagic necrosis and showed a large longitudinal fissure. Microscopically, Zygomycota were observed in both the lungs and heart, while Aspergillus was found in the middle lobe of the right lung. Zygomycosis, which usually has a poor prognosis, is assumed to have induced hemorrhagic infarction of the lungs, inducing pulmonary bleeding and necrosis, despite the use of lipid formulations of amphotericin B, which are effective medicines against Zygomycota. Keywords: pulmonary fissure, zygomycosis, aspergillosis, lung, immunosuppression

  20. Autopsy cases of hepatocellular carcinoma in atomic bomb survivors

    Since 1956, 388 autopsy cases of hepatocellular carcinoma (HCC) have been obtained at the Hiroshima Red Cross and A-Bomb Survivors Hospital, which consisted of those of proximately exposed 52 A-bomb survivors (mean age, 63.8 years), 105 distally exposed A-bomb survivors (mean age, 64.2 years), and the other 231 non-exposed patients (mean age, 60.6 years). Since 1985, the incidence of HCC tended to be higher in both proximately and distally exposed groups than the non-exposed group. There was no consistent tendency for the incidence of HCC by ages at autopsy and A-bombing. The incidence of liver cirrhosis was approximately 2 times higher in males than females in the non-exposed group, although no gender difference existed after 1981. In the exposed group, the incidence was similar in male and female groups. Approximately 90% of HCC patients had coexistent liver cirrhosis. Liver cirrhosis was associated with HCC in 50-60%. No significant differences in these incidences were observed between the exposed and non-exposed groups. The proportion of liver cirrhosis associated with HCC became constant in patients over the age of 40 in the non-exposed group. In the exposed group, on the other hand, the proportion reached the peak in those in their fifties and sixties. Survival time tended to be longer in the exposed group than the non-exposed group. The patients in the non-exposed group tended to have histologically atypical type and metastases, as compared with those in the exposed group. (N.K.)

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

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

    2010-08-15

    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

  3. A bite into the history of the autopsy : From ancient roots to modern decay.

    Burton, Julian L

    2005-12-01

    The autopsy has had a checkered history, much of which has been surrounded by controversy. The roots of human dissection are found in the ancient world where rumors flourished that the prosectors of the day were engaged in vivisection as well as dissection. Bound up with the prevailing religious and political systems of the day, the autopsy has alternately been prohibited and encouraged, used to explore the nature of disease, and conceal questionable political policy. This review explores the history of the autopsy from its ancient roots in Egypt, Mesopotamia, Alexandria, and the Far East through the dark ages to medieval times and beyond into the renaissance. The development of the autopsy in Europe during the 17th to 19th centuries is discussed before briefly considering the decline of this diagnostic tool in the 20th century. PMID:25868447

  6. Pulmonary blastomycosis on autopsy: a rare case report

    Shweta Rana

    2015-02-01

    Full Text Available A case of pulmonary blastomycosis on autopsy in a middle aged male from rural background is presented herewith. Blastomycosis is a pyogranulomatous disease caused by the dimorphic fungus blastomyces dermatitidis. Blastomycosis is endemic in regions of North America that border the Great Lakes. It is one of the great mimickers in medicine. Pulmonary blastomycosis has a broad range of clinical presentations, varying from completely asymptomatic pulmonary infiltrates to diffuse and massive parenchymal involvement that can lead to Acute Respiratory Distress Syndrome (ARDS. Human infection occurs when soil containing microfoci of mycelia is distributed and airborne conidia are inhaled. If natural defences in the alveoli fail to contain the infection, lymphohematogenous dissemination ensues. Diagnosis is based on culture and direct visualization of round, multinucleated yeast forms that produce daughter cells from a single broad- based bud. Most of the cases of blastomycosis reported in India are imported from the endemic areas of the World except a few authochthonous cases in North India. [Int J Res Med Sci 2015; 3(2.000: 498-501

  7. Hypertrophic cardiomyopathy: an autopsy analysis of 14 cases.

    2001-07-01

    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.

  8. An autopsy case with malignant liver tumor caused by thorotrast

    This paper reported the roentgenographic, laparoscopic and autopsy findings of a patient with thorotrast liver complicated with malignant liver tumor, which was considered to develop 35 years after the infusion of thorotrast. Laboratory findings of a 67-year-old man, who got a war wound before 35 years and received angiography by using thorotrast at that time, indicated marked symptoms of liver parenchymal disturbance, biliary occlusion and malignant liver tumor. X-ray examination revealed arborescent and reticular abnormal shadow in the liver and the spleen and spotted shadow at the liver hilus. Laparoscopic findings revealed reticulate grayish-yellow particles adhered to the recessus of the nodules in the surface of the liver. Liver biopsy showed deposition of thorotrast granules and necrosis and scar formation of the hepatic cells. Microautoradiography revealed ?-track from the region where thorotrast was deposited. Postmortem findings revealed thorotrast liver cirrhosis, primary liver tumor (reticulo-endothelial sarcoma), circular calcium deposit in the hepatic duct, the bile duct and the portal vein, and cholangitis, demonstrating delayed disturbance by thorotrast.

    2011-01-01

    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.

    Purpose Assessment of body size at autopsy is important for interpreting organ weight measurements and in some cases body identification. The reliability of post-mortem body size measurements, the causes for perturbations in these measurements from their corresponding pre-mortem values, and the impact of such perturbations on heart weight interpretation have not been fully explored. Methods Autopsy body length and weight measurements and pre-mortem height and body weight measurements were compared in 132 autopsies. Clinical records were evaluated for peripheral edema and serum albumin levels. Causes of death, body cavity fluid collections, and heart weights were obtained from the autopsy reports. A subset of patients underwent quantitative post-mortem computed tomography assessment of anasarca. Results At autopsy, body weight differed from the pre-mortem value by 11 ± 1 %, compared with -0.2 ± 0.3 % for body length (P edema (14 ± 2 % vs. 7 ± 2 %, P = 0.01), serum albumin edema/anasarca. Alterations in body weight at autopsy can confound the interpretation of organ weight measurements. PMID:27020890

  13. An autopsy of dead planetary systems with COS

    Debes, John

    2014-10-01

    We propose to use HST/COS to conduct autopsies of dead planetary systems around UV bright hydrogen-white dwarfs (WDs), which have dust disks found via their mid-IR emission in excess of that expected from the photosphere. As part of a WISE survey, and followed up with a combination of NASA Keck HIRES/Magellan MIKE optical spectroscopy, we have identified three new systems that are accreting dust. These WDs are bright in the mid-IR and UV, gold-standard targets for studies with HST/COS and later with JWST. The dusty material is debris resulting from the tidal disruption of exo-asteroids that accrete onto the WD surface. Many atomic elements from the accreted and dissociated dust particles are detectable with COS, enabling abundance determinations of exo-asteroidal material. Moreover, the photospheric abundances of this material can be directly compared with a determination of the dust mineralogy obtained with future JWST mid-IR spectroscopy-our proposed UV observations provide complementary constraints on mineralogical compositions of the accreting dust particles. UV spectroscopy is crucial for cataloging elemental abundances for these exo-asteroids. For the majority of WDs, optical spectroscopy reveals only a couple of lines of Ca or Mg, while UV spectroscopy captures lines from Al, Fe, Si, C, Ni, O, S, Cr, P, and Ti. Obtaining the elemental abundances of exo-asteroids is comparable to the spectroscopic characterization of transiting exoplanets or protoplanetary disks-all of these techniques determine how the chemical diversity of planetary systems translate into planetary architectures and the probability of habitable planets around solar-type stars.

  14. Neuropathology and general autopsy findings in nondemented aged subjects.

    Jellinger, Kurt A; Attems, Johannes

    2012-01-01

    A retrospective study of the essential general pathology and neuropathological features in 100 nondemented individuals aged 65 years or older (mean 81.23 ± 5.47 y) was performed using semiquantitative methods. 91% of the patients had a history of hypertension, 31% malignancies, 24% COPD, 18% myocardial infarction, and 4% stroke. Major causes of death were cardiovascular decompensation, pneumonia, acute myocardial infarction, and malignancies. General autopsy revealed severe systemic and coronary atherosclerosis in 86 and 90%, respectively, renal angioangiolosclerosis in 82%, acute or recurrent myocardial infarction in 65%, and other diseases. Neuropathology showed average brain weight of 1,163 ± 113 g, mild to moderate brain atrophy, absent to mild atherosclerosis of large cerebral arteries in 46%, mild, moderate and severe one in 31, 17, and 6%, respectively. There were considerable discrepancies in the severity between generalized/ aortic and intracranial atherosclerosis, only less than one-third being comparable. Negative Khachaturian criteria and CERAD Stage 0 were observed in 83 and 86%, respectively, only 13% with CERAD Stage A, and 1% Stage B. Braak neuritic stages ranged from 0 to II (53%), II - III (29%) to III - IV (18%), none scoring Grade V or VI. The average Braak score was 2.3 ± 0.8. Vascular pathologies were common; CAA was absent in 61%, mild or moderate in 36% and severe in 3%. Mild to severe lacunar state in basal ganglia and/or white matter was seen in 73%, hippocampal sclerosis in 3 cases, while only 9% were free of cerebrovascular lesions. Lewy bodies were observed in 5 brains involving substantia nigra (n = 3), cerebral cortex (n = 1) and medulla oblongata (n = 1), 1 case representing incidental Lewy body disease. ? pathology in brainstem was observed in 60 cases (60%). Mixed cerebral pathologies (cerebrovascular lesions and moderate neuritic Braak stages) were observed in 6 cases (mean age 89.6 y). The importance of mixed pathologies in nondemented elderly, being less frequent than in other studies, remains to be elucidated. PMID:22385790

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

    Sudha M

    2009-10-01

    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.

  16. The use of CT-scanning at the medicolegal external postmortem examination and at the forensic autopsy

    Leth, Peter Mygind

    2006-01-01

    Introduction: Can CT-scanning of deceased at the medico legal external examination improve the selection of cases to autopsy? Is CT-scanning a substitute or a supplement to the traditional forensic autopsy? Material: In 2006 60 deceased individuals from Southern Denmark (counties of Fyn and...... Sønderjylland) (15 females and 45 males) were CT-scanned before autopsy. Method: A double-blind prospective investigation of CT-scanning in autopsy cases. A multislice spiral CT-scanner (Siemens Somatom Spirit) was used. Data from the CT-scanning and the autopsy were registered in a computer database and...... compared. Results: The scanning could be performed in 10 minutes per case. In approximately a third of the cases the cause of death could be established by CT-scanning alone. CT-scanning was found to be most useful in cases of traumatic death, and was superior to autopsy in visualizing fractures...

  17. Verbal autopsy: current practices and challenges / Autopsie verbale: pratiques actuelles et défis à surmonter / Autopsias verbales: práctica y retos

    Nadia, Soleman; Daniel, Chandramohan; Kenji, Shibuya.

    2006-03-01

    Full Text Available Los datos sobre causas de defunción obtenidos a partir de autopsias verbales (AV) son usados con creciente frecuencia con fines de planificación de la salud, establecimiento de prioridades, seguimiento y evaluación en los países con sistemas de registro civil incompletos o inexistentes. En algunas r [...] egiones del mundo es el único método disponible para poder estimar la distribución de las causas de mortalidad. Hoy día el método de las AV se utiliza sistemáticamente en más de 35 lugares, sobre todo en África y Asia. En este artículo presentamos un panorama general del sistema de las AV y los resultados de un análisis de los instrumentos de AV y los procedimientos operativos utilizados en los sitios de vigilancia demográfica y los sistemas de registro de estadísticas vitales por muestreo. Solicitamos información a 36 sitios sobre el terreno acerca de los procedimientos operativos y examinamos 18 cuestionarios de autopsia verbal y 10 listas de causas de defunción usadas en 13 países. El formato y el contenido de los cuestionarios de AV, los procedimientos operativos sobre el terreno, las listas de las causas de defunción y los procedimientos empleados para calcular las causas de mortalidad a partir de las AV diferían sustancialmente de un sitio a otro. Analizamos las consecuencias de utilizar distintos métodos y llegamos a la conclusión de que es necesario normalizar los instrumentos y los procedimientos de AV y hacerlos más fiables si se desea hacer comparaciones más precisas de los datos de AV en los planos nacional e internacional. Ponemos de relieve, además, las medidas adicionales que habría que adoptar para desarrollar un procedimiento de AV normalizado. Abstract in english Cause-of-death data derived from verbal autopsy (VA) are increasingly used for health planning, priority setting, monitoring and evaluation in countries with incomplete or no vital registration systems. In some regions of the world it is the only method available to obtain estimates on the distribut [...] ion of causes of death. Currently, the VA method is routinely used at over 35 sites, mainly in Africa and Asia. In this paper, we present an overview of the VA process and the results of a review of VA tools and operating procedures used at demographic surveillance sites and sample vital registration systems. We asked for information from 36 field sites about field-operating procedures and reviewed 18 verbal autopsy questionnaires and 10 cause-of-death lists used in 13 countries. The format and content of VA questionnaires, field-operating procedures, cause-of-death lists and the procedures to derive causes of death from VA process varied substantially among sites. We discuss the consequences of using varied methods and conclude that the VA tools and procedures must be standardized and reliable in order to make accurate national and international comparisons of VA data. We also highlight further steps needed in the development of a standard VA process.

    Kim, Na Rae; Seo, Jin Won; Lim, Young Hwan; Ham, Hyoung Suk; Huh, Wooseong; Han, Joungho

    2012-01-01

    Metastatic calcification is rare; it is found during autopsy in patients who underwent hemodialysis. Diffuse calcium precipitation of small and medium-sized cutaneous vessels, known as calciphylaxis, can result in progressive tissue necrosis secondary to vascular calcification. This condition most commonly involves the skin; however, a rare occurrence of visceral calciphylaxis has been reported. Here we report on an autopsy case. Despite a thorough evaluation, and even performing an autopsy, ...

  1. Radiography after unexpected death in infants and children compared to autopsy

    Postmortem radiography may reveal skeletal and soft-tissue abnormalities of importance for the diagnosis of cause of death. To review the radiographs of children under 3 years of age who had died suddenly and unexpectedly. To compare the radiological and autopsy findings evaluating possible differences in children dying of SIDS and of an explainable cause. A total of 110 consecutive skeletal surveys performed between 1998 and 2002 were reviewed. All but one were performed before autopsy and comprised AP views of the appendicular and axial skeleton and thorax/abdomen, lateral views of the axial skeleton and thorax, and two oblique views of the ribs. Radiography and autopsy findings were compared. Causes of death were classified as SIDS/borderline SIDS (n = 52) and non-SIDS (n = 58), with one case of abuse. In 102 infants there were 150 pathological findings, 88 involving the chest, 24 skeletal, and 38 miscellaneous findings. The radiological-pathological agreement was poor concerning pulmonary findings. Skeletal findings were sometimes important for the final diagnosis. Radiography revealed many skeletal and soft-tissue findings. Pulmonary pathology was most frequently found, but showed poor agreement with autopsy findings. Recognizing skeletal findings related to abuse is important, as these may escape recognition at autopsy. (orig.)

  2. Autopsy in Islam: Considerations for Deceased Muslims and Their Families Currently and in the Future.

    Sajid, Mohammed Imran

    2016-03-01

    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.

    2014-03-01

    The codeine to morphine concentration ratio is used in forensic toxicology to assess if codeine has been ingested alone or if morphine and/or heroin have been ingested in addition. In our experience, this interpretation is more difficult in autopsy cases compared with samples from living persons, since high morphine concentrations are observed in cases where only codeine is assumed to have been ingested. We have investigated if codeine and morphine glucuronides are subject to cleavage to the same extent in living and autopsy cases in vitro. We included whole blood samples from eight living subjects and nine forensic autopsy cases, where only codeine ingestion was suspected. All samples were incubated for 2 weeks at 37°C and analyzed for codeine and six codeine metabolites using liquid chromatography tandem mass spectrometry. A reduction in the codeine to morphine concentration ratio was found, both in samples from living subjects (mean 33%, range 22-50%) and autopsy cases (mean 37%, range 13-54%). The increase in the morphine concentrations was greater in the autopsy cases (mean 85%, max 200%) compared with that of the living cases (mean 51%, max 87%). No changes were seen for codeine or codeine-6-glucuronide concentrations. The altered ratios might mislead the forensic toxicologist to suspect morphine or heroin consumption in cases where only codeine has been ingested. PMID:24324229

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

    Treacy, A

    2013-03-01

    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\

  5. Inventory of ABCC-RERF autopsies Hiroshima and Nagasaki, 1948-1980

    This is the fourth inventory of ABCC-RERF autopsies which covers those performed from 1948-80 (the other three inventories). For general information the introduction of the third inventory (1948-70) is included with some modification, and deaths and autopsy rates for 1971-80 are added. ABCC-RERF performed 10,096 autopsies (6,555 in Hiroshima and 3,541 in Nagasaki) from 1948 to 1980. Protocols, tissues, sections, smears, etc., assembled by the collaborating institutions were examined by members of the ABCC Department of Pathology who completed ABCC records for each case. Copies of all protocols, gross tissues, and histological sections were placed in a designated repository in the Medical School of each city where they are available to all qualified and interested investigators.

    2004-10-01

    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.

    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.

    2015-11-01

    Medical disputes in China are historically poorly documented. In particular, autopsy-based evaluation and its impact on medical malpractice claims remain largely unstudied. This study aims to document autopsy findings and medical malpractice in one of the largest cities of China, Wuhan, located in Hubei Province. A total of 519 autopsies were performed by the Department of Forensic Medicine, Wuhan University School of Medicine, Wuhan, China, over a 10-year period between 2004 and 2013. Of these cases, 190 (36.6%) were associated with medical malpractice claims. Joint evaluation by forensic pathologists and clinicians confirmed that 97 (51.1%) of the 190 claims were approved medical malpractice cases. The percentage of approved malpractice cases increased with patient age and varied according to medical setting, physician specialty, and organ system. The clinico-pathological diagnostic discrepancy was significantly different among various physician specialties (P = 0.031) and organ systems (P = 0.000). Of those cases involved in malpractice claims, aortic dissection, coronary heart disease, and acute respiratory infection were most common. Association between incorrect diagnosis and malpractice was significant (P = 0.001). This is the first report on China's medical malpractice and findings at autopsy which reflects the current state of health care services in one of the biggest cities in China. PMID:26559306

  18. [Autopsies in Switzerland, Germany and Austria: considerations about legal facts and the current situation].

    Tag, B

    2011-11-01

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

  19. Hiding in Plain Sight: Clinically Unrecognized Fatal Tooth Asphyxia Revealed by the Forensic Autopsy.

    Armstrong, Erica J

    2016-03-01

    Fatal asphyxia by choking whether by food or foreign material remains an uncommon occurrence affecting mainly those at the extremes of age and with variable and sometimes misleading clinical presentations. Prompt clinical recognition of impending airway obstruction afforded by complete physical examination and assessment is paramount for prevention of morbidity and mortality in these cases. In the elderly, a death initially presenting with sudden cardiorespiratory collapse may be erroneously certified as due to natural disease without performance of an autopsy. Fortunately, deaths subsequent to cardiorespiratory collapse, where results of the clinical work-up fail to identify an etiology and medical history is insufficient, are reportable, falling under the jurisdiction of the medical examiner/coroner. The performance of an autopsy in the evaluation of a sudden death arising after hospitalization in which the etiology remains unclear can provide valuable information to our clinical colleagues that they can apply to more timely diagnosis and treatment. Furthermore, the forensic autopsy offers clarification and answers to questions of medicolegal importance. This is particularly true for choking deaths.?Presented is a choking death after tooth aspiration whereby the forensic autopsy provided specific anatomic correlation to the clinical clues not recognized before death and provided the true cause of death.

  4. Correlation of diagnostic imaging and autopsy findings of eight patients with acquired immune deficiency syndrome

    Objective: To investigate the imaging findings with pathologic correlation in patients with acquired immune deficiency syndrome (AIDS). Methods: Imaging findings, autopsy and pathological data were retrospectively analyzed in eight patients with AIDS. Routine CT scanning of different body parts was performed during their hospitalization. CT scanning was performed from the skull to the pelvis immediately following their death. After routine formalin fixing, 7 cadavers were cross sectioned for autopsy in freezing state and 1 for gross autopsy. Tissues were obtained from each sections and organs for pathological examinations. Results: The autopsy data showed parasitic infections (5 cases), bacterial infections (3 cases), fungal infections (2 cases), virus infections (2 cases), lymphoma (1 case) and cerebrovascular diseases (1 case)in eight patients with AIDS. The CT scanning demonstrated symmetrical ground glass liked shadows with pulmonary hilus as the center in 5 cases of pulmonary PCP infection; pulmonary patchy shadows, scattering distribution of nodular shadows, extensive military nodular shadows with even distribution and tuberculous pleurisy; cloudy shadows for 2 cases of fungi infection with multiple foci of chronic inflammation; pulmonary net-like parenchymal changes for 2 cases of pulmonary CMV infection; thickened intestinal wall and narrowed intestinal lumen for 1 case of intestinal tumor; low density shadows of brain tissue for 1 case of CMV encephalitis and MRI findings of high T1 and high T2 signals as well as MRA findings of broken vascular channels in liquefied areas of brain tissues; patchy low density areas inside a cyst of brain for one case of brain toxoplasmosis infection; multiple small patchy low density areas in cerebral basal ganglia for one case of brain cryptococcus infection. Conclusions: In AIDS patients, infection and tumor may occur in various organs resulting in complex symptoms, which makes it more complicated and difficult to make accurate diagnosis. A correlative study of imaging findings and pathological manifestation of AIDS patients at autopsy could be helpful for clinical diagnosis. (authors)

  5. Let's talk about death: data collection for verbal autopsies in a demographic and health surveillance site in Malaysia

    Pascale A. Allotey

    2015-07-01

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

  6. Post-mortem imaging as an alternative to autopsy in the diagnosis of adult deaths: a validation study

    2012-01-01

    Summary Background Public objection to autopsy has led to a search for minimally invasive alternatives. Imaging has potential, but its accuracy is unknown. We aimed to identify the accuracy of post-mortem CT and MRI compared with full autopsy in a large series of adult deaths. Methods This study was undertaken at two UK centres in Manchester and Oxford between April, 2006, and November, 2008. We used whole-body CT and MRI followed by full autopsy to investigate a series of adult deaths that w...

  7. [An autopsy case of triple primary cancers consisting of glioblastoma multiforme of the pons, colon cancer and rectal carcinoid--a statistical analysis of cases of brain tumor combined with other primary cancers in Japan autopsy annuals].

    Hayashi, K; Ohtsuki, Y; Sonobe, H; Takahashi, K; Wada, S; Yoshida, K

    1987-11-01

    An autopsy case of glioblastoma multiforms of the pons with a colon cancer, a rectal carcinoid, a renal adenoma and three gastric leiomyomas in a 81-year-old-woman is reported with a statistical analysis on multiple primary cancers associated with primary brain tumors as reported in the Japan autopsy annuals. Out of 329, 705 autopsy cases from 1975 to 1984 in the Japan autopsy registry, double cancers and triple cancers that included a primary brain tumor amounted to 123 cases (0.037%) and 12 cases (0.0036%), respectively. Other sites for primary cancers were the thyroid (23%), the stomach (15%), the lungs (12%), and the colon (10%) in that order of frequency. PMID:2826842

  8. An autopsy case of thyroid cancer following radiotherapy for tongue cancer

    The patient was a 61 year old woman who was exposed to a-bomb (38 rad) at the age of 29. She had tongue cancer and received radiotherapy for it, and her thyroid cancer was found by autopsy. Besides Bleomycin, Maruyama vaccine, and so on, 6,000 R of radiation was given over lymph nodes of the neck, but she died 1 year and 8 months after the treatment without any effect. Besides squamous cell carcinoma of the tongue, multi-centric papillary adenocarcinoma in the left lobe and papillary adenocarcinoma scattering in the right lobe of the thyroid gland were found by autopsy. The metastases of cancer to lymph nodes of the neck were also detected. Thyroid cancer in this case seemed to be highly related with a-bomb exposure and radiotherapy for tongue cancer. Therefore, it is necessary to decide irradiation field carefully when radiotherapy is performed. (Tsunoda, M.)

  9. Autopsy findings in a long-term survivor with glioblastoma multiforme. Case report

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

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

    Bhakti D. Deshmukh

    2012-01-01

    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.

    2014-01-01

    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...... from 1992 to 2010. Eighty-four suicidal deaths with morphologically normal hearts served as controls. Polymerase chain reaction was used for the detection of the viral genomes (adenovirus, enterovirus, and PVB) in myocardial tissue specimens. The distinction between acute and persistent PVB infection...... 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...

    Larsen, S; Rygaard, K; Asnaes, S; Spang-Thomsen, M

    1992-01-01

    21-118 h postmortem. Extracted RNA and DNA were examined by Northern and Southern blot analysis using oligo-labelled human DNA probes recognizing gene transcripts of 2-5 kb. The results indicated that, in general, Northern blot analysis was feasible with the applied probes when the tissue was......Fresh biopsy material for molecular biological investigations is not obtainable from all relevant normal human tissues. We studied the feasibility of using RNA and DNA from autopsies for Northern and Southern blot analysis. Tissue samples from seven organs were obtained from 10 autopsies performed...... obtained less than two days postmortem. Histological examination showing slight or no autolysis and the presence of ribosomal bands after gel electrophoresis were both indicative parameters of RNA preservation. DNA was appropriate for Southern blotting when the tissue was obtained less than three to five...

  13. Aggregate effects of vascular risk factors on cerebrovascular changes in autopsy-confirmed Alzheimer's disease.

    Bangen, Katherine J; Nation, Daniel A; Delano-Wood, Lisa; Weissberger, Gali H; Hansen, Lawrence A; Galasko, Douglas R; Salmon, David P; Bondi, Mark W

    2015-04-01

    We examined the relationships of antemortem vascular risk factors to postmortem cerebrovascular and Alzheimer's disease (AD) pathologies. Eighty-four AD patients underwent an assessment of vascular risk (blood pressure, cholesterol, smoking, cardiovascular disease, diabetes, atrial fibrillation, transient ischemic attack [TIA], or stroke) and later underwent brain autopsy. Given our aim to examine mild cerebrovascular changes (CVCs), individuals were excluded if autopsy revealed large stroke. The most common forms of CVC were circle of Willis atherosclerosis followed by arteriosclerosis, lacunes, and microinfarcts. Excluding the history of TIA/clinical stroke, individual vascular risk factors were not associated with CVC. However, the presence of multiple vascular risk factors was associated with CVC. Furthermore, the presence of CVC was associated with lower Braak and Braak stage. These findings highlight the importance of aggregate risk in the vascular contribution to dementia. Interventions designed to maintain cerebrovascular health may represent important opportunities for preventing or delaying dementia, even when AD is the dominant pathology. PMID:25022538

  14. Malignant Amelanotic Melanoma of the Pleura without Primary Skin Lesion:An Autopsy Case Report

    Nakanishi,Kuniaki

    2009-12-01

    Full Text Available Melanoma metastasizing to the lungs is common, but primary pulmonary or pleural melanoma is extremely rare. We present an autopsy case of malignant melanoma of the pleura without primary skin lesion in a 49-year-old man. A mass found in the right chest was diagnosed as spindle cell sarcoma by antemortem fine-needle aspiration cytology. At autopsy, a yellow-white tumor located primarily in the right visceral pleura (diagnosed as an amelanotic melanoma was found to have invaded into the right lung, right parietal pleura, and right diaphragm, and to have metastasized into the left lung and visceral pleura, thyroid, and left adrenal gland. No primary site was found. The tumor cells were positive for S100 and focally positive for HMB-45, but negative for other markers. Immuno-histochemical examination for S100 and HMB-45 would thus appear to be useful for the diagnosis of an amelanotic melanoma.

  15. Autopsy reenactment--a useful technique in the evaluation of adhesive tape asphyxia.

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

    2014-05-01

    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. PMID:24502562

  16. Relation of radiation to gastric carcinoma observed in autopsy cases in a fixed population, Hiroshima and nagasaki 1961 - 74

    A study was made of the relation to atomic bomb radiation of 535 cases of gastric carcinoma among 4,694 deaths occurring in a fixed population of Hiroshima and Nagasaki who were autopsied between 1961 and 1974. The proportion of all autopsies with gastric carcinoma as autopsy diagnosis tended to be high in the high dose group, but it could not be concluded with the present amount of information that there is a relation between gastric carcinoma and radiation in this autopsy study. Although no specific distribution of the histological types of gastric carcinoma was noted by radiation dose, the data indicated increases in the degree of extension of tumor cells in the gastric wall and the degree of metastasis to the lymph nodes seemed to be high in the high dose group.

    1993-01-01

    Jarcho-Levin syndrome (JLS) is a condition manifested by malformations of vertebral bodes and related ribs. There are two major subtypes spondylocostal dysostosis and spondylothoracic dysostosis, with different survival rates, associated malformations, and inheritance patterns. We have experienced an autopsy case of a premature female fetus with multiple congenital anomalies. She was 30 weeks of gestational age, born as the second baby of twins and expired shortly after birth. A post-mortem e...

    2015-01-01

    Sorafenib is a multikinase inhibitor currently approved in Japan for the treatment of unresectable hepatocellular carcinoma. Interstitial pneumonia induced by sorafenib may have a fatal outcome, and therefore, has recently been the focus of many studies. The current report presents an autopsy case of diffuse alveolar damage (DAD) that occurred in a 59-year-old male, who had been treated with sorafenib. The patient had been given sorafenib for six months and had exhibited no respiratory sympto...

    2015-01-01

    Background: Reliable data on the distribution of causes of death (COD) in a population are fundamental to good public health practice. In the absence of comprehensive medical certification of deaths, the only feasible way to collect essential mortality data is verbal autopsy (VA). The Tariff Method was developed by the Population Health Metrics Research Consortium (PHMRC) to ascertain COD from VA information. Given its potential for improving information about COD, there is interest in refini...

    Oliveira, Cristiano Claudino; Marques, Mariângela Esther Alencar

    2014-01-01

    Pyomyositis is the bacterial infection of skeletal muscle, usually accompanied by abscesses. The main etiologic agent is Staphylococcus aureus. There are rare cases attributed to Streptococcus pneumoniae. This paper presents an autopsy of a four year old child with multiple congenital intramuscular hemangiomas that developed pneumococcal pyomyositis associated with meningitis. The authors propose the hypothesis that patients with hemangiomas, mainly the intramuscular type, may also represent ...

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

    Todorović Miloš S.

    2011-01-01

    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 results.

  5. An analytical method for the determination of plutonium in autopsy samples

    A sensitive method for the determination of plutonium in autopsy samples is described. After a suitable chemical pretreatment of the samples the plutonium is separated by extraction chromatography with tri-n-octylphosphine oxide (TOPO) supported on microporus polyethylene. After electrodeposition of plutonium the activity is counted by alpha spectroscopy. The global yield was 75-80%. The reagent blank activity was such to allow the determination of some femtocuries of plutonium

  6. Cause of death in 1144 patients with diabetes mellitus: an autopsy study.

    Joron, G. E.; Laryea, E; Jaeger, D; MacDonald, L.

    1986-01-01

    The pathological reports for all patients over 13 years of age who had had an autopsy at one of three university-affiliated hospitals between 1967 and 1976 were reviewed to determine the principal cause of death. The clinical records of the patients with diabetes were reviewed to verify the diagnosis and to determine the known duration of diabetes. There were 1144 patients with diabetes mellitus and 5674 without. The sex distribution was similar in the two groups. The patients with diabetes w...

  7. Validity of Verbal Autopsy Procedures for Determining Malaria Deaths in Different Epidemiological Settings in Uganda

    Mpimbaza, A; Filler, S; Katureebe, A.; Kinara, SO; Nzabandora, E; Quick, L.; Ratcliffe, A; Wabwire-Mangen, F; Chandramohan, D; Staedke, SG

    2011-01-01

    BACKGROUND: Verbal autopsy (VA) procedures can be used to estimate cause of death in settings with inadequate vital registries. However, the sensitivity of VA for determining malaria-specific mortality may be low, and may vary with transmission intensity. We assessed the diagnostic accuracy of VA procedures as compared to hospital medical records for determining cause of death in children under five in three different malaria transmission settings in Uganda, including Tororo (high), Kampala (...

  8. Café coronary syndrome-fatal choking on food: an autopsy approach.

    Wick, Regula; Gilbert, John D; Byard, Roger W

    2006-04-01

    To examine the characteristic features of fatal food asphyxia and to develop an autopsy approach to such cases a retrospective study of autopsy files was undertaken at Forensic Science SA (Adelaide, Australia) over a 10 year period from 1993 to 2002 for all cases of food asphyxia/café coronary syndrome. Forty-four cases were identified (M;F=21:23), with one infant (11 mths) and 43 adults (30-96 yrs; mean 68.9 yrs), with a preponderance of victims (57%) aged between 71 and 90 yrs. Deaths occurred in nursing homes (N=22) cases, at home (N=11) and in restaurants (N=4). Twenty-seven of the victims (61%) had histories of neurological or psychiatric disorders such as dementia (N=8), schizophrenia (N=6), Alzheimer disease (N=4), atherosclerotic cerebrovascular disease (N=4), mental impairment (N=2), multiple sclerosis (N=1), Parkinson disease (N=1) and obsessive-compulsive disorder (N=1). Twenty-seven cases (61%) were described as either edentulous or having significant numbers of teeth missing. Toxicological evaluation of blood revealed alcohol and a variety of psychotropic prescription medications in 19 cases. Sudden collapse during or shortly after a meal should always raise the possibility of café coronary and the autopsy examination should not only attempt to demonstrate airway occlusion by a bolus of food, but also to identify or exclude underlying neurological disease. Such cases may raise issues concerning adequacy of care and appropriateness of medication. The diagnosis of café coronary syndrome can only be made with confidence after the clinical history and circumstances of death have been clearly established, impacted material has been demonstrated in the airway at autopsy (or recorded by those attempting resuscitation), risk factors have been identified and other possible causes of death have been excluded.

  9. A STUDY OF LUNG PATHOLOGY IN PEDIATRICS AUTOPSIES: AN 8 YEAR STUDY

    Majethia Nikhil

    2014-11-01

    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

    2015-01-01

    Diagnosing clinical progressive supranuclear palsy (PSP) is challenging. We hypothesize that there are more cases of pathological PSP than have been clinically identified, but its diagnosis is challenging because the initial lesions and progression of PSP have not yet been clarified. The purpose of our study was to clarify the incidence of PSP in consecutive autopsy cases and identify pathological characteristics of early PSP. We investigated 324 consecutive autopsy patients from a general geriatric hospital (age, mean±SD=82.5±8.7 years). Paraffin sections of the midbrain were immunostained with anti 4-repeat tau antibodies (RD4). We selected cases showing RD4-positive neurofibrillary tangles and tufted astrocytes in the midbrain sections. Then, we used anti-phosphorylated tau antibody to immunostain sections from the basal ganglia, subthalamic nucleus, midbrain, pons, medulla, and cerebellum. Of the 324 patients, 35 had RD4-positive structures in the midbrain. From these 35 cases, we excluded those for which autopsies confirmed definite PSP (n=5) and cases of corticobasal degeneration (n=1), Alzheimer's disease (n=11), dementia of grain (n=10), and neurofibrillary tangles predominant forms of senile dementia (n=2), leaving 8 cases. We diagnosed these 8 cases as pure PSP-type tauopathy. Pure PSP-type tauopathy was detected in 2.5% of the consecutive autopsy cases, and this incidence was 1.6 times greater than that of neuropathologically definite PSP. This pure PSP-type tauopathy likely indicates preclinical stages of PSP. Furthermore, the novel neuropathological finding, which we term "preclinical PSP," is unique and has not previously been reported. In order to elucidate the causes and pathological mechanisms of PSP, preclinical PSP should be investigated further. PMID:26823029

    Chronic infections including the cysticercosis induce inflammatory cells to produce free radicals and synthesize carcinogenic toxins. The cells with genetic mutations proliferate in a disorganized manner, leading to the development of neoplasia. The aim of the present study was to demonstrate the relation between cysticercosis and neoplasia. Patients autopsied were divided into 4 groups: patients with neoplasia and cysticercosis (NC), patients with neoplasia only (NN), patients with cysticerc...

    Objective: To examine if there is widespread inflammation in the brain of patients with chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) syndrome by using histology and ultra-high-field MRI at 7.0T. Methods: We performed a detailed neuropathologic examination in 4 cases, including 1 autopsy case, and studied 2 additional patients by MRI at 7.0T to examine (1) extension of inflammation to areas appearing normal on 3.0T MRI, (2) potential advantages of 7.0T MRI compared to 3.0T MRI in reflecting widespread inflammation, perivascular pathology, and axonal damage, and (3) the possibility of lymphoma. Results: In the autopsy case, perivascular inflammation dominated by CD4+ T cells was not only detected in the brainstem and cerebellum but also in brain areas with normal appearance on 3.0T MRI, including supratentorial regions and cranial nerve roots. There was no evidence of lymphoma in any of the 4 patients. The 7.0T MRI in clinical remission also revealed supratentorial lesions and perivascular pathology in vivo with contrast-enhancing lesions centered around a small venous vessel. Ultra-high-field MRI at 7.0T disclosed prominent T1 hypointensities in the brainstem, which were not seen on 3.0T MRI. This corresponded to neuropathologic detection of axonal injury in the autopsy case. Conclusion: Our findings suggest more widespread perivascular inflammation and postinflammatory axonal injury in patients with CLIPPERS. PMID:27144217

    2016-04-01

    Snake bite is a major public health problem specially in a rural region where agricultural work is the major source of employment. A retrospective study was undertaken of all cases of deaths due to snake bite autopsied at the Mortuary of Pravara Rural Hospital, Loni a rural area in Western Maharashtra over a period of 10 years from January 2004 to December 2014. Data of the study was gathered from autopsy reports and hospital records. The cases represented approximately 2.13% (54) of the total 2539 medico legal autopsies conducted during the study period. Most of the deaths (42.60%) occurred in the age group of 11-30 years and both males and females were affected in almost equal proportions. There was a marked increase in the number of cases in monsoon season (59.26%). The lower extremity was the most frequently involved site of bite (62.96%). Snakes were identified in 43 cases (79.63%) and among the identified cases the most common culprit was Viper amounting to 29.63% of cases followed by Krait causing 24.07% of the deaths. The findings in our study reflects the necessity of educating the rural community regarding the hazards of snake bite, importance of early medical attention and to avoid wasting vital time being engaged by traditional healers.

    2015-01-01

    Patient: Male, 74 Final Diagnosis: Spindle cell carcinoma of the lung Symptoms: — Medication: Pemetrexed • carboplatin Clinical Procedure: Biopsy and autopsy Specialty: Oncology Objective: Rare disease Background: Spindle cell carcinoma (SPCC) of the lung is a subset of sarcomatoid carcinoma. Its clinical features are unclear because of its rarity. Here, we report an autopsy case of SPCC and review CT findings and chemotherapeutic regimens based on previous reports of this disease. To our knowledge, this is the first reported case of pemetrexed used to treat SPCC. Case Report: A 74-year-old Japanese male presented with dyspnea and contrast-enhanced computed tomography (CT) showed abundant left pleural effusion and a mass in lower lobe of the left lung. By the tumor biopsy, he was diagnosed for SPCC of the lung, cT3N0M1a, stage IV. The tumor was resistant to chemotherapy with carboplatin and pemetrexed, and rapidly progressed. Autopsy revealed abundant hemorrhage within the tumor, which apparently reflects a low-density area in CT. Conclusions: Present case and the accumulation of cases indicate that low-density areas in CT and rapid tumor progression may be common SPCC findings. PMID:26558362

    The presence of tissue cysts of Toxoplasma gondii has only poorly been investigated in autopsy series. We determined the presence of T. gondii cysts in a series of 51 autopsies in a public hospital using immunohistochemistry of brain and heart tissues. The association of tissue cysts with the general characteristics of the autopsy cases was also investigated. Of the 51 cases studied, five (9.8%) were positive by immunohistochemistry for T. gondii cysts in the brain. None of the heart specimen...

  1. A semi-structured interview for psychological autopsy in suicide cases

    Werlang Blanca Guevara

    2003-01-01

    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.

  2. Agreement between death-certificate and autopsy diagnoses among atomic-bomb survivors

    Using the Atomic Bomb Casualty Commission/Radiation Effects Research Foundation series of over 5000 autopsies, we examined death-certificate accuracy for several disease categories and assessed the effect of potential modifying factors on this accuracy. For 12 cause-of-death categories, the overall percent agreement between death-certificate and autopsy diagnoses was only 52.5%. Although neoplasms had the highest detection rate (on the death certificate) in the study, still almost 25% of cancers diagnosed at autopsy were missed on the death certificate. Only for neoplasms and external causes of death were confirmation and detection rates above 70%. Confirmation rates were between 50% and 70% for infectious and parasitic diseases and heart and other vascular diseases. Detection rates reached a similar level for infectious and parasitic, cerebrovascular, and digestive diseases. Specificity rates were above 90% for all but the cerebrovascular disease category. Overall agreement decreased with increasing age of the decedents and was lower for deaths occurring outside of hospital vs those occurring in a hospital. There was some suggestion that agreement rates were higher for more-recent deaths but no indication that radiation dose, sex, city of residence, or inclusion in a biennial clinical-examination program influenced agreement. Because the inaccuracy of death-certificate diagnoses can have major implications for many aspects of health research and planning, it is important to be aware that death-certificate accuracy is low and can vary widely depending on the patient's age at death and the place of death.

    Establishing the identity of the deceased becomes essential when highly decomposed bodies, mutilated body parts or skeletal remains are recovered from mass fatality sites. In these situations, estimation of stature along with other parameters such as age, sex and race/ethnicity becomes important to establish the biological profile of the deceased. Following the Maoist insurgency in Nepal, there have been numerous discoveries of unidentified human remains in mass graves or otherwise. No systemic studies and anthropological data on the Nepalese population however, is available posing problems in anthropologic evaluation of the remains. The sample of the present study consisted of 200 autopsied cases (148 males and 52 female adult cadavers). During the autopsy, the scalp was reflected after giving a coronal incision extending from one mastoid to the other exposing the cranium in each case. Maximum cranial length (MCL), maximum cranial breadth (MCB), bi-zygomatic breadth (BZB), minimum frontal breadth (MFB) and length of parietal chord (PC) were then measured. Stature was measured as the length of the body from head to heel in centimeters with the heel, buttocks, back of the shoulders and the head in contact with the autopsy table. Linear and stepwise multiple regression models were derived for estimation of stature from cranial measurements. Univariate, bivariate and multivariate regression models show statistically significant correlation between stature and the cranial measurements. The present study opines that the stature estimation from cranial dimensions using multivariate linear regression models is more accurate than those of the univariate and bivariate regression models. This study presents a rare data from Nepalese population that show typical Asian features and thus, is significant from anthropologic and genetic point of view. The study observations further contribute a baseline data bank for forensic pathologists and specialists. PMID:25595547

    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.

  5. Postmortem heart weight modelled using piecewise linear regression in 27,645 medicolegal autopsy cases.

    Wingren, Carl Johan; Ottosson, Anders

    2015-07-01

    The interpretation of postmortem heart weight is often difficult, and references for normal heart weight are important. However, to assess the cause of death at a medicolegal autopsy it is also important to have references based on an unselected population of medicolegal autopsy cases with non-natural causes of death (not due directly to disease). We aimed at studying and deriving references for adult heart weight by considering sex, age and body size in cases with an external cause of death. We identified all medicolegal autopsies in Sweden from 1999 to 2013 (n=79,778) and included 27,645 cases. We applied multivariate piecewise linear regression models in three strata of body mass-underweight, normal-/overweight and obesity. We observed that approximately 50% of the variation in heart weight was explained by age, sex and body size. These variables were slightly less important in explaining the variation in heart weight in the underweight and obese compared to in those normal or overweight. Based on the linear regression models we present equations to calculate the predicted heart weight with reference intervals using age, sex, body weight and height. We provide an online heart weight calculator (http://lundforensicmedicine.com) based on these equations. In the forensic interpretation of postmortem heart weights, we suggest that heart weight references derived in cases with an external cause of death is an important complement to references solely based on healthy and normal hearts. Furthermore, the heart weight references presented are derived from a large population, with sufficient numbers for separate models in underweight, normal-/overweight and obese populations.

    Toxicological analysis is indispensable in forensic autopsy laboratories, but often depends on the limitations of individual institutions. The present study reviewed routine drug screening data of forensic autopsy cases (n=2996) during an 18.5-year period (January 1996-June 2014) at our institute to examine the efficacy of the procedures and findings in autopsy diagnosis and interpretation. Drug screening was performed using on-site immunoassay screening devices and gas chromatography/mass spectrometry (GC/MS) in all cases, followed by re-examination using GC/MS and liquid chromatography/tandem mass spectrometry (LC/MS/MS) at a cooperating institute in specific cases in the last 4 years. GC/MS detected drugs in 486 cases (16.2%), including amphetamines (n=160), major tranquilizers (n=72), minor tranquilizers (n=294), antidepressants (n=21), cold remedies (n=77), and other drugs (n=19). Among these cases, fatal intoxication (n=123) involved amphetamines (n=73), major tranquilizers (n=37), minor tranquilizers (n=86), antidepressants (n=3), and cold remedies (n=9); most cases involved self-administration, alleged suicide and accidental overdose, while homicide was not included. These drugs were also identified in other manners of death, including homicide (n=40/372), suicide (n=34/226), accidental falls (n=27/129), and natural death (n=72/514). In these cases, on-site immunoassay screening of drugs of abuse showed negative findings in 2440 cases (81.4% in all cases), while GC/MS detected other drugs in 218 cases (7.3% in all cases), including several antipsychotic drugs, acetaminophen and salicylic acid. Further analysis using LC/MS/MS detected low concentrations of benzodiazepines in 32 cases, and also anti-diabetic and hypertensive drugs in a case of fatal abuse. These observations indicate the efficacy of systematic routine toxicological analysis to investigate not only the cause of death but also the background of fatalities in forensic autopsy. The provision of extensive drug screening is needed for forensic and social risk management, considering the marked diversity of medical and illicit drugs. PMID:25637163

    Human Immunodeficiency Virus (HIV) infection is a true plague and a major health concern globally. It is one of the most significant pandemics in recorded history. Despite worldwide efforts to fight the pandemic, and now with the re-emergence of tuberculosis, those clinicians, personnel performing autopsies and medical caregivers are again at risk in the work place, especially in developing countries. We describe a case where a drug abuser, whose addiction was concealed by his parents, died in hospital. He was tested HIV-negative there. A medical tangle ensued and forensic autopsy was carried out. Autopsy confirmed he was an intravenous drug addict and had tuberculosis. Post-mortem blood was positive for HIV antibodies and he was diagnosed with AIDS. Due to social stigmas, lack of knowledge or inefficient medical laboratory procedures etc, such type of cases can become a hazard to those attending the sick and to autopsy pathologists alike. We provide the case description, autopsy findings and review of pertinent literature. PMID:21420653

  8. Birth attendants as perinatal verbal autopsy respondents in low-and middle-income countries: a viable alternative?

    C Engmann

    2012-03-01

    Full Text Available OBJECTIVE: To assess the feasibility of using birth attendants instead of bereaved mothers as perinatal verbal autopsy respondents. METHODS: Verbal autopsy interviews for early neonatal deaths and stillbirths were conducted separately among mothers (reference standard and birth attendants in 38 communities in four developing countries. Concordance between maternal and attendant responses was calculated for all questions, for categories of questions and for individual questions. The sensitivity and specificity of individual questions with the birth attendant as respondent were assessed. FINDINGS: For early neonatal deaths, concordance across all questions was 94%. Concordance was at least 95% for more than half the questions on maternal medical history, birth attendance and neonate characteristics. Concordance on any given question was never less than 80%. Sensitivity and specificity varied across individual questions, more than 80% of which had a sensitivity of at least 80% and a specificity of at least 90%. For stillbirths, concordance across all questions was 93%. Concordance was 95% or greater more than half the time for questions on birth attendance, site of delivery and stillborn characteristics. Sensitivity and specificity varied across individual questions. Over 60% of the questions had a sensitivity of at least 80% and over 80% of them had a specificity of at least 90%. Overall, the causes of death established through verbal autopsy were similar, regardless of respondent. CONCLUSION: Birth attendants can substitute for bereaved mothers as verbal autopsy respondents. The questions in existing harmonized verbal autopsy questionnaires need further refinement, as their sensitivity and specificity differ widely.

  9. Signifance of Liver Ductal Plate Malformation in Differential Diagnosis of Autosomal Recessive Polycystic Kidney Disease: An Autopsy Case

    2015-03-01

    Full Text Available Cystic renal diseases are a group of disorders that cause neonatal deaths. Autosomal recessive polycystic kidney disease (ARPKD is a rare entity which may be associated with liver disorders. Presenting autopsy case was stillbirth in 31 + 1 gestational week. In postmortem autopsy,viewed through the capsule, the renal surface was filled by innumerable miniature cysts about 1 mm in diameter. istopathological examination revealed multiple cysts of variable size in the renal medulla and tortuosity, elongation of ductal plate of liver. The autopsy was evaluated as ARPKD and ductal plate malformation. This disorder is not usually compatible with life. Some of the other cystic kidney diseases have better clinical outcome and must be distinguished from ARPKD. [Cukurova Med J 2015; 40(Suppl 1: 18-21

  10. Cardiovascular Damage in Alzheimer Disease: Autopsy Findings From the Bryan ADRC

    Corder Elizabeth H.

    2005-01-01

    Full Text Available Autopsy information on cardiovascular damage was investigated for pathologically confirmed Alzheimer disease (AD patients (n = 84 and non-AD control patients (n = 60 . The 51 relevant items were entered into a grade-of-membership model to describe vascular damage in AD. Five latent groups were identified “I: early-onset AD,” “II: controls, cancer,” “III: controls, extensive atherosclerosis,” “IV: late-onset AD, male,” and “V: late-onset AD, female.” Expectedly, Groups IV and V had elevated APOE ϵ 4 frequency. Unexpectedly, there was limited atherosclerosis and frequent myocardial valve and ventricular damage. The findings do not indicate a strong relationship between atherosclerosis and AD, although both are associated with the APOE ϵ 4 . 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 ϵ 4 contributes directly to heart valve and myocardial damage.

  11. Sudden cardiac death in the young: the molecular autopsy and a practical approach to surviving relatives.

    Semsarian, Christopher; Ingles, Jodie; Wilde, Arthur A M

    2015-06-01

    The sudden death of a young, apparently fit and healthy person is amongst the most challenging scenarios in clinical medicine. Sudden cardiac death (SCD) is a devastating and tragic outcome 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, genetic (inherited) cardiac disorders comprise a substantial proportion of SCD cases aged 40 years and less. This includes the primary arrhythmogenic disorders such as long QT syndromes and inherited cardiomyopathies, namely hypertrophic cardiomyopathy. In up to 30% of young SCD, no cause of death is identified at postmortem, so-called autopsy-negative or sudden arrhythmic death syndrome (SADS). Management of families following SCD begins with a concerted effort to identify the cause of death in the decedent, based on either premorbid clinical details or the pathological findings at postmortem. Where no cause of death is identified, genetic testing of deoxyribonucleic acid extracted from postmortem blood (the molecular autopsy) may identify a cause of death in up to 30% of SADS cases. Irrespective of the genetic testing considerations, all families in which a sudden unexplained death has occurred require targeted and standardized clinical testing in an attempt to identify relatives who may be at-risk of having the same inherited heart disease and therefore also predisposed to an increased risk of SCD. Optimal care of SCD families therefore requires dedicated and appropriately trained staff in the setting of a specialized multidisciplinary cardiac genetic clinic. PMID:25765769

  12. Autopsy findings in carotid arterial rupture following radiotherapy of head and neck advanced carcinoma

    The influence of radiotherapy in advanced head and neck cancer was investigated by autopsy of head and neck patients who had had carotid artery rupture. Twenty-five cases of head and neck cancer revealed carotid artery rupture among the 255 head and neck cases autopsied from 1972 to 1985. The rate of carotid artery rupture in hypopharyngeal cancer was 8/32 (25%); in oral cancer 8/55 (14.5%), and in other cancers 9/165 (5.4%). In localization of ruptured arteries there were 9 cases of common carotid artery, 14 cases of external carotid artery, one case of internal carotid artery, and one unknown. These cases were irradiated using more than 70 Gy. The following reasons for carotid artery rupture were suspected: 1. There was a tumor with deep ulceration and necrosis near the vessel. 2. The wall of the artery had radiation angitis. 3. The artery wall was necrotic because of invasion by the tumor. 4. Thrombosis developed with ensuant rupture of the artery. Radiotherapy for advanced cancer of the head and neck is necessary to control pain and as palliative treatment, but to avoid rupture of the carotid artery, pain clinic techniques and chemotherapy as palliative treatment for this kinds of terminal condition should also be considered.

  13. Histopathologic findings in autopsy cases after radiotherapy for cancer pain from bone marrow metastasis

    The purpose of this was to study the mechanisms of cancer pain and effects of irradiation in metastatic bone marrow patients, histopathologically. Sixteen autopsy cases including 9 breast tumors, 4 hepatic cell carcinomas, 2 gastric cancers and 1 triple cancer of the renal pelvis, urinary bladder and liver were studied. Symptomatically, the effects of radiotherapy (36∼56 Gy) for cancer pain were freedom from pain in 4 (25%), pain relief in 8 (50%), no effect in 3 (18.8%) and undetectable in 1. The sites of irradiation were thoracic in 7, lumbar in 5, thoracolumbar in 3, and cervicothoracic vertebra in 1. At autopsy, no cancer cells were found at the site of irradiation in 5 subjects. The histopathologic appearance of painful metastases to bones was periosteal infiltration in 8, perineural invasion in 3, nervous compression in 4 and compression fracture or collapse in 8. The reaction of metastatic bone marrow to irradiation showed mixed type in 8, intertrabecullar types in 4, osteolytic type in 1, and osteoplastic type in 2. Cancer pain was associated with several histopathologic findings, and the histopathological effects of radiation for such pain were weak. Further histopathologic study of the mechanisms of cancer pain and effects of irradiation may be necessary for better quality of life (QOL) for patients. (author)

    2012-01-01

    Full Text Available Background: The first goal of National Rural Health Mission (NRHM and the fourth goal of Millennium Development are to reduce under-five mortality rate. In India, data is available for aprox. 3% of the perinatal deaths. The need for good quality data on perinatal deaths is mandatory for public health planning and resources allocation. This has lead to a renewed interest in Verbal autopsy (VA in poor resource settings. Objective: To validate a simplified community-based VA instrument. Materials and Methods: A simplified community-based VA instrument was developed. The sample size of 50 was calculated at power – 80%, significance – 5% and sensitivity – 70%. ANMs were trained to assign COD according to the ICD – 10. Following which they administered Verbal Autopsies for every perinatal death occurring in their area. A panel of 3 Physicians was formed who reviewed the VA data and assigned cause of death according to the ICD–10. Kappa Statistics was used to measure the degree of agreement between the ANM and Physician panel assigned COD. Results: Out of 50 Perinatal Deaths, the COD assigned by ANM and the COD assigned by the Physician panel were same for 40 of the perinatal deaths, which showed the agreement of 80% [Kappa Statistics = 0.838; P = 0.000 (<0.001] which indicates statistically significant agreement. There was agreement of 93% for 14 Stillbirths and 75% agreement for 36 Early Neonatal Deaths.

  15. Histopathological change of the metastatic bone marrow. Response for radio- and combination chemotherapy at autopsy cases

    The purpose of this study was to determine the histopathologic therapeutic effects in metastatic bone marrow for various therapy in cancer patients. Autopsy cases at Shikoku Cancer Center Hospital, mainly cancer of breast, stomach, lung and prostate examined radiotherapy (28-60 Gy) and chemotherapy and/or endocrine chemotherapy (medroxyprogesterone acetate, tamoxifen). Histological evaluation of effects for radio-and chemotherapy have been criteria of UICC and criteria for the evaluation of the clinical and pathological effects by Japan Society for Cancer Therapy. The precise effects for various therapy is difficult to measure objectively in metastatic bone. Histopathologic changes of metastatic bone marrow for radiotherapy revealed decrease and degeneration of tumor cells - swelling, vacuoles of cytoplasm and nuclei, bizarre and giant multinucleated giant cells etc. Stromal reaction was found postnecrotic fresh and/or old granulation-fibrosis and hyalinization, woven bone formation and fatty marrow. Systemic therapy of breast cancer revealed stromal fibrosis and chondroid ossification more than other tumors and therapy. Morphological features of metastatic bone marrow at autopsy cases may be necessary from viewpoint of therapeutic effects. (author)

    We report an autopsy case of hemopericardium caused by rupture of a ventricular aneurysm associated with acute myocarditis in an infant boy aged 2years and 10months. Three days before his death, the patient developed fever. On the day of death, he described an urge to defecate and attempted to do so in an upright position. While straining to defecate without success for a prolonged period, he stopped breathing and collapsed. On autopsy, his heart weighed 91.7g and cardiac tamponade was evident, the pericardial cavity being filled with 140mL of blood that had come from a 1.5-cm-long rupture in a 2.7×1.5cm ventricular aneurysm in the posterior left ventricular wall. Patchy grayish-white discoloration was noted in the myocardium. Histologically, CD3-positive T lymphocytic infiltration accompanied by pronounced macrophage infiltration was observed in the myocardium. Hemorrhagic necrosis was detected in the area of the ventricular aneurysm. Staining for matrix metalloproteinase (MMP) expression revealed abundant MMP-2, MMP-7, and MMP-9. Polymerase chain reaction to detect viruses failed to identify any specific causative viruses in the myocardium. In this case of lymphocytic (viral) and histiocytic myocarditis with pronounced macrophage infiltration and upregulation of MMP expression, myocardial remodeling and associated wall weakening had resulted in formation and rupture of an aneurysm.

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

    Mariana Bellaguarda de Castro Sepulvida

    2014-03-01

    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.

    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.

    2015-06-01

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

  20. Sharp Force Injuries at the University Hospital of the West Indies, Kingston, Jamaica: A Seventeen-year Autopsy Review

    Neblett, A; Williams, NP

    2014-01-01

    ABSTRACT Objectives: This study aimed to ascertain the prevalence and patterns of fatal sharp force injuries, victims' demographics, cause of death and average survival time at the University Hospital of the West Indies (UHWI), Kingston, Jamaica. Methods: The autopsy records for 1990-2010 were searched for fatal cases of sharp force injuries. The records for 1998-2001were not located. A 17-year retrospective analysis was therefore performed and findings for the two periods, 1990-1997 and 2002-2010 were compared. All data were obtained from the provisional anatomical diagnoses (PAD) autopsy reports. Results: During the 17-year period, 57/4264 autopsies were performed for sharp force injuries, yielding an overall autopsy prevalence rate of 1.34%; 1.25%, 26/2086 (95% CI 0.77, 1.73) in Period 1 and 1.42%, 31/2178 (95% CI 0.92, 1.92) in Period 2. The majority were males (91.1%), in the age group 15-39 years (77%), mean age of 30.9 years (range = 17-65 years). Stab wounds predominated (91.3%) and the chest was the area most frequently stabbed (42.1%). In the 24 fatalities due to chest injuries only, eight (33.3%) had injuries to the heart alone. Forty-five patients (79.0%) died within 24 hours from exsanguination. Injury documentation at autopsy was deficient. Conclusion: Stabbing was the most common sharp force injury, mainly involving the chest, and young men were at greatest risk. Most patients died from exsanguination within 24 hours of admission. Introduction of synoptic-type reports for both clinical and autopsy examination may improve documentation. PMID:25781278

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

    Adair Timothy

    2010-03-01

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

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

    Thayyil Sudhin

    2011-12-01

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

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

    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.

    1978-08-01

    Ten pairs of twin lambs 118--122 days of gestation were given either natural surfactant or diluent endotracheally before the first breath. By using the premature twin lamb model, we have been able to show that instillation of natural surfactant produced 100% survival for the duration of the study period (2 hr); stable blood gases on room air; lungs that became increasingly compliant while on the respirator; generally well aerated lungs at autopsy; good lung pressure-volume relationships; normal lung surface tension measurements; and histologic evidence of good alveolar expansion with large amounts of free intraluminal phospholipid, no epithelial damage, and no hyaline membranes. It is concluded that tracheal instillation of natural surfactant into the premature lamb protects the lungs from developing many features characteristic of the respiratory distress syndrome.

    1999-11-01

    We report the autopsy case of a 41-year old passenger who suffered a significant head injury with a typical ring fracture at the base of the skull as a result of a violent fall from a bicycle. Several reports about ring fractures of the base of the skull revealed that they were due to crashing a car at high speed, a collision and/or a fall while riding a motorcycle and a fall in piloting a gyrocopter and so on resulting in severe injury to another part of the body. In this case, the ring fracture occurred when his spine was pushed up by high impact of the parieto-occipital region against the ground. PMID:10723970

  8. Men in despair: a qualitative psychological autopsy study of suicide in northern Uganda.

    Kizza, Dorothy; Knizek, Birthe Loa; Kinyanda, Eugene; Hjelmeland, Heidi

    2012-11-01

    The psychosocial circumstances surrounding men's suicide in postconflict Central Northern Uganda were investigated using qualitative psychological autopsy interviews. Records of 17 men who died by suicide were identified through police and local leaders in Internally Displaced Peoples' camps of Amuru and Gulu Districts. Two to five significant others were interviewed around each case. Data were analyzed by interpretative phenomenological analysis (IPA). Lost dignity and social value, lack of hope for the family's future, overwhelming family responsibility, and mental illness were circumstances found to have preceded the suicides. The protracted war in the Northern region of Uganda left men in rural communities feeling disempowered and disenfranchised. This may have contributed to suicidal behavior in some of them. Suicide prevention in this area needs to be multidisciplinary with an emphasis on helping both men and women understand and deal with the many social changes that have evolved over time and affected their traditional roles and responsibilities.

    2007-04-01

    Full Text Available Abstract Background Glomerulocystic kidney disease is an uncommon type of cystic renal disease. It is characterized by cortical microsysts, which are represented by cystic dilatation of Bowman's spaces. Case presentation We describe a case of glomerulocystic disease in a neonate and another in an abortus associated with tracheo-oesophageal fistula and megacystic-megaureter syndrome. The kidney on autopsy was sponge-like and revealed presence of cysts corresponding to dilatations of Bowman's space microscopically. In these two cases, the Glomerulocystic Kidney Disease in one case corresponded to a sporadic form and, in the other, to a syndromic, non-heritable form of glomerulocystic kidney disease. Conclusion The associated anomalies in Glomerulocystic Kidney disease are well described in the literature. Two more new unrelated associations are described in this article.

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

    Emi Yasuda

    2013-01-01

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

  11. An autopsy case of peritoneal malignant mesothelioma in a radiation technologist

    A case of peritoneal malignant mesothelioma in a radiation technologist, who had worked in this field for 34 years, is reported. Histopathologically, a biopsy specimen from the retroperitoneal tumor revealed a biphasic type of malignant mesothelioma. Electron microscopy disclosed that the tumor cells contained prominent microvilli, basal laminae adjacent to the stroma, junctional complexes, desmosomes, tonofilaments, clusters of glycogen granules, well developed rough endoplasmic reticulum (RER), confronting cisternae showing direct continuity with the RER and membrane-bound granules suggestive of secretory activity. No increased amount of asbestos was detected in autopsied lung material or the peritoneal mesothelioma. The estimated cumulative dose of occupational irradiation was calculated to be about 40 to 50 rad at most. Irradiation was discussed in relation to the etiology of the peritoneal mesothelioma.

  12. Chronic radium intoxication: clinical and autopsy findings in long-term New Jersey survivors

    After briefly tracing the development of investigations into radium intoxication in the 1920s, the author presents detailed clinical and autopsy findings from each of the 42 people associated with the New Jersey radium industry during the second and third decades of this century who survived their initial occupational exposure to 226Ra and 228Ra for 25 years or longer. Preterminal 226Ra burdens are known for 31 cases. 24 of the 42 had malignant tumors or blood dyscrasias. Female, but not male, life spans were shortened and fertility possibly reduced. These and a variety of additional findings are discussed and deductions suggested. It was not possible to identify dose-response patterns and the study neither confirms nor challenges the current lifetime maximum permissible human 226Ra content of 0.1 ?Ci. Clinical and laboratory data are presented in 52 tables in an appendix

    2014-10-01

    Full Text Available : After proper preparations of body, removal of brain, brain stem with spinal cord were done. Total thirty (30 cadavers were dissected in a span of three (3 years in Katihar Medical College, Katihar, Bihar, India with good results. The removal of vault of skull, squamous part of occipital bone, posterior arch of atlas, followed by bilateral laminectomy of vertebrae, helps in viewing of brain, brain stem and spinal cord along with spinal nerve roots and cauda equina. This approach helps in total removal of brain, brain stem and spinal cord with its covering with large venous sinuses remaining intact however small venous sinuses are sacrificed in this process. The specimen thus obtained can be used for autopsy or anatomical study.

  14. Fetal Alcohol Syndrome in Sudden Unexpected Death in Infancy: A Case Report in Medicolegal Autopsy.

    Tangsermkijsakul, Aphinan

    2016-03-01

    Fetal alcohol spectrum disorder is a range of birth defects associated with prenatal alcohol exposure. Fetal alcohol syndrome (FAS) is the most serious form of fetal alcohol spectrum disorder. Infants with FAS are prone to death because of various physical abnormalities. Consequently, infants with FAS may be presented in the medicolegal investigation as a form of sudden unexpected death in infancy. The author reported a 6-month-old male infant who was found dead at home. The history of maternal ethanol consumption during pregnancy was obtained. The infant was diagnosed with FAS at the autopsy because he was presented with postnatal growth retardation, multiple facial abnormalities, and abnormal brain structures, which met the criteria of FAS. The cause of death was severe aspiration pneumonia. The purposes of this case report are to show an uncommon manifestation of sudden unexpected death in infancy case for the forensic pathologists and to emphasize on the national healthcare problem.

  15. Understanding Suicide in Socially Vulnerable Contexts: Psychological Autopsy in a Small Town in Mexico.

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

    2016-02-01

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

  16. Proton induced X-ray emission analysis of Pima Indian autopsy tissues

    Proton particle-induced X-ray emission (PIXE) analysis has been used to determine the concentrations of K, Ca, Ti, Mn, Fe, Co, Ni, Cu, Zn, Se, Br, Rb, Sr, Cd, Cs, and Pb in liver, spleen, aorta, kidney medulla, kidney cortex, abdominal fat, pancreas, and hair taken at autopsy from Southwest Indians, primarily of the Pima tribe. Samples were prepared by a low-temperature ashing procedure which is compared to other preparation methods. Data were analyzed by a computer program, ANALEX. The accuracy is tested with NBS standard reference materials and with flame atomic absorption spectrophotometric results. The precision allowed observation of element concentration differences between replicate, half-gram samples of the same tissue. The differences appeared to arise from tissue inhomogeneities. 5 figures, 4 tables

    Braggion-Santos, Maria Fernanda; Volpe, Gustavo Jardim; Pazin-Filho, Antonio; Maciel, Benedito Carlos; Marin-Neto, José Antonio; Schmidt, André

    2015-01-01

    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. PMID:25424162

    2011-03-01

    Full Text Available Abstract Background Pulmonary tumor thrombotic microangiopathy (PTTM has been known as a rare and serious cancer-related pulmonary complication. However, the pathogenesis and pathophysiology of this debilitating condition still remains obscure and no effective management was recommended. The present study aims to elucidate the pathophysiology of PTTM. Methods Autopsy records were searched to extract cases of pulmonary tumor embolism induced by metastasis of gastric carcinoma in the Toho University Omori Medical Center from 2000 to 2006. And then, tissue sections of extracted cases were prepared for not only light microscopic observation but morphometric analysis with the use of selected PTTM cases. Results Six autopsies involved PTTM and clinicopathological data of them were summarized. There was a significant negative association between pulmonary arterial diameter and stenosis rate in four cases. Although all cases showed an increase of stenosis rate to some degree, the degree of stenosis rate varied from case to case. Significant differences were found for average stenosis rate between the under 100 micrometer group or the 100 to 300 micrometer group and the 300 micrometer group in four cases. However, no significant differences were found for average stenosis rate between the under 100 micrometer group and the 100 to 300 micrometer group in all cases. Meanwhile, all cases showed positive reactivity for tissue factor (TF, five showed positive reactivity for vascular endothelial growth factor (VEGF, and three showed positive reactivity for osteopontin (OPN. Conclusions In the present study, we revealed that the degree of luminal narrowing of the pulmonary arteries varied from case to case, and our results suggested that pulmonary hypertension in PTTM occurs in selected cases which have a widespread pulmonary lesion with severe luminal narrowing in the smaller arteries. Furthermore, our immunohistochemical examination indicated that gastric carcinoma indicating PTTM shows a higher TF-positive rate than typical gastric carcinoma. However, it remains still obscuring whether gastric carcinoma indicating PTTM shows a higher VEGF or OPN-positive rate as determined by immunohistochemistry.

    Background In this study, our aim was to evaluate the fatal occupational accidents that occurred in Zonguldak coal mines between the years 2005–2008. Material/Methods We retrospectively evaluated 42 fatal coal mine occupational accidents in Zonguldak (Turkey) between the years 2005–2008. The forensic records of autopsies referred to the chief prosecutors’ office during 2005–2008 were reviewed retrospectively. There were 42 cases. The cases were evaluated with respect to age, mechanism of injury, body region of wound, cause of death, and legality of the mine. Results Ages of the deceased ranged between 17 and 52 (median: 32.9 yrs). Deaths were mostly in the 21–30 (35.8%), and 31–40 (30.9%) age groups. Only 1 case was younger than 18 years of age. Review of occupational fatalities has revealed that fatal accidents occurred mostly (76.2%) in the private, and fewer (23.8%) in the public mining enterprises. Crime scene investigation findings have demonstrated that of all occupational deaths (total n=42), 27 (64.3%) were due to subsidence, followed by methane gas poisoning (n=6, 14.2%), tram crash (n=3, 7.1%), log falls (n=2, 4.8%), electrocution (n=2, 4.8%), and methane explosion (n=2, 4.8%). Conclusions Despite laws and regulations concerning mining and because of problems in their implementation, Turkey leads the world in work-related accidents, occupational injuries, and deaths. Evaluation of autopsy findings of deaths in fatal occupational accidents occurring in coal mines is quite important in planning to decrease rates of occupational fatalities. PMID:24643126

    Prostate cancer screening may detect nonprogressive cancers, leading to overdiagnosis and overtreatment. The potential for overdiagnosis can be assessed from the reservoir of prostate cancer in autopsy studies that report incidental prostate cancer rates in men who died of other causes. We aimed to estimate the age-specific incidental cancer prevalence from all published autopsy studies. We identified eligible studies by searches of Medline and Embase, forward and backward citation searches and contacting authors. We screened the titles and abstracts of all articles; checked the full-text articles for eligibility and extracted clinical and pathology data using standardized forms. We extracted mean cancer prevalence, age-specific cancer prevalence and validity measures and then pooled data from all studies using logistic regression models with random effects. The 29 studies included in the review dated from 1948 to 2013. Incidental cancer was detected in all populations, with no obvious time trends in prevalence. Prostate cancer prevalence increased with each decade of age, OR = 1.7 (1.6-1.8), and was higher in studies that used the Gleason score, OR = 2.0 (1.1-3.7). No other factors were significantly predictive. The estimated mean cancer prevalence increased in a nonlinear fashion from 5% (95% CI: 3-8%) at age 79 years. There was substantial variation between populations in estimated cancer prevalence. There is a substantial reservoir of incidental prostate cancer which increases with age. The high risk of overdiagnosis limits the usefulness of prostate cancer screening. PMID:25821151

    2006-11-01

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

    Twenty autopsy cases with 2009 pandemic influenza A (2009 H1N1) virus infection, performed between August 2009 and February 2010, were histopathologically analyzed. Hematoxylin-eosin staining, immunohistochemistry for type A influenza nucleoprotein antigen, and real-time reverse transcription-PCR assay for viral RNA were performed on formalin-fixed and paraffin-embedded specimens. In addition, the D222G amino acid substitution in influenza virus hemagglutinin, which binds to specific cell receptors, was analyzed in formalin-fixed and paraffin-embedded trachea and lung sections by direct sequencing of PCR-amplified products. There were several histopathological patterns in the lung according to the most remarkable findings in each case: acute diffuse alveolar damage (DAD) with a hyaline membrane (four cases), organized DAD (one case), acute massive intra-alveolar edema with variable degrees of hemorrhage (three cases), neutrophilic bronchopneumonia (five cases) and tracheobronchitis with limited histopathological changes in alveoli (four cases). In two cases, the main findings were due to preexisting disease. Influenza virus antigen was only detected in the respiratory tract in 10 cases by immunohistochemistry. The antigen was detected in type II pneumocytes (three cases) in the epithelial cells of the trachea, bronchi and glands (six cases), and in the epithelial cells in both of the above (one case). The four cases with acute DAD presented with antigen-positive type II pneumocytes. In one case, the D222G substitution was detected in the lung as a major sequence, although 222D was prominent in the trachea, suggesting that selection of the viral clones occurred in the respiratory tract. In five cases, the pathogenesis of 2009 H1N1 was confirmed to be viral infection in pneumocytes, which caused severe alveolar damage and fatal viral pneumonia. Further studies on both host and viral factors in autopsy or biopsy materials will be essential to elucidate the other pathogenic factors involved in influenza virus infection. PMID:21874012

    Maria Fernanda Braggion-Santos

    2015-02-01

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

  4. An autopsy case of osteosarcoma of right mandibula developed after irradiation to the right cervical region for treatment of Hodgkin's disease

    An autopsy case of osteosarcoma derived from the right mandible was reported. The case was a 64 year-old-female who received radiotherapy (60Co) 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.

    2011-08-01

    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 a cause of death did not substantively influence the pattern of mortality estimated. Substantially abbreviated and simplified verbal autopsy questionnaires might provide robust information about high-level mortality patterns.

  6. Medico-legal autopsies as a source of information to improve patient safety.

    Madea, Burkhard

    2009-04-01

    Clear data on the epidemiology of medical malpractice are missing, at least for Germany. Especially data on the frequency of malpractice claims in penal and civil law are not available. However, from epidemiological and healthcare research some data on the frequency of adverse events (AE), preventable adverse events (PAE) and negligent adverse events (NAE) are available. According to a review of the German Alliance of Patient Safety adverse events can be expected in 5-10%, preventable adverse events in 2-4%, negligent adverse events in about 1% and lethal outcome in about 0.1% of hospitalized patients. However, these data are not compatible with figures from civil and penal law and there seems to be a great "litigation gap". Data on malpractice cases are available from the files of the arbitration committees on medical malpractice, files of liability insurance companies and files of the institutes of forensic medicine. However, these files are not complete and data sources may have some interferences. The arbitration committees are, however, mainly dealing with living patients. Lethal cases are a special subgroup and the best available data source are the files of the institutes of forensic medicine. This subgroup is of special importance since death is the most severe outcome of medical malpractice and the reproach to have caused the death of a patient by medical negligence is the most severe malpractice claim. From a retrospective multicentre study on autopsies performed in cases of medical malpractice claims (altogether 101.358 autopsies, 4450 due to medical malpractice claims) the most important data will be presented (disciplines concerned, cause of accusation, classification of accusation, causes of preliminary proceedings, occupational group and number of approved medical malpractice, outcome of medical malpractice proceedings). However, these data are not only of a descriptive value but have utmost importance also for risk analysis and to increase patient safety. A thorough evaluation of serious incidences, although less sophisticated than a root cause analysis, produces far more information than the usual hospital reporting system. Identification and evaluation of errors as well as reporting of errors may also contribute to the prevention of errors which is among other medical disciplines also a task of forensic medicine.

    Background Maternal mortality is a major health problem concentrated in resource-poor regions. Accurate data on its causes using rigorous methods is lacking, but is essential to guide policy-makers and health professionals to reduce this intolerable burden. The aim of this study was to accurately describe the causes of maternal death in order to contribute to its reduction, in one of the regions of the world with the highest maternal mortality ratios. Methods and Findings We conducted a prospective study between October 2002 and December 2004 on the causes of maternal death in a tertiary-level referral hospital in Maputo, Mozambique, using complete autopsies with histological examination. HIV detection was done by virologic and serologic tests, and malaria was diagnosed by histological and parasitological examination. During 26 mo there were 179 maternal deaths, of which 139 (77.6%) had a complete autopsy and formed the basis of this analysis. Of those with test results, 65 women (52.8%) were HIV-positive. Obstetric complications accounted for 38.2% of deaths; haemorrhage was the most frequent cause (16.6%). Nonobstetric conditions accounted for 56.1% of deaths; HIV/AIDS, pyogenic bronchopneumonia, severe malaria, and pyogenic meningitis were the most common causes (12.9%, 12.2%, 10.1% and 7.2% respectively). Mycobacterial infection was found in 12 (8.6%) maternal deaths. Conclusions In this tertiary hospital in Mozambique, infectious diseases accounted for at least half of all maternal deaths, even though effective treatment is available for the four leading causes, HIV/AIDS, pyogenic bronchopneumonia, severe malaria, and pyogenic meningitis. These observations highlight the need to implement effective and available prevention tools, such as intermittent preventive treatment and insecticide-treated bed-nets for malaria, antiretroviral drugs for HIV/AIDS, or vaccines and effective antibiotics for pneumococcal and meningococcal diseases. Deaths due to obstetric causes represent a failure of health-care systems and require urgent improvement. PMID:18288887

  8. Racking the brain: Detection of cerebral edema on postmortem computed tomography compared with forensic autopsy

    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 white matter ratio was >1.58 when leukoencephalopathy was excluded. Conclusions: Despite normal postmortem changes, generalized brain edema can be differentiated on postmortem computed tomography, and white and gray matter Hounsfield measurements help to determine the cause of death in cases of intoxication or asphyxia. Racking the brain about feasible applications for a precise and reliable brain diagnostic forensic radiology method has just begun

  9. [On the value of tattoos for identifying unknown bodies - a retrospective study of forensic autopsy cases from Giessen, Germany].

    2016-01-01

    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. PMID:26934763

  10. Relation of radiation to gastric carcinoma observed in autopsy cases in the life span study sample, Hiroshima and Nagasaki, 1961-74

    A study was made of the relation to atomic bomb radiation of 535 cases of gastric carcinoma among 4,694 deaths occurring in a fixed population of Hiroshima and Nagasaki who were autopsied between 1961 and 1974. The proportion of all autopsies with gastric carcinoma as autopsy diagnosis tended to be high in the high dose group, but it could not be concluded with the present amount of information that there is a relation between gastric carcinoma and radiation in this autopsy study. Although no specific distribution of the histological types of gastric carcinoma was noted by radiation dose, the data indicated increases in the degree of extension of tumor cells in the gastric wall and the degree of metastasis to the lymph nodes seemed to be high in the high dose group.

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

    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. 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. 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. 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 individual head modelling and trauma analysis

  15. Autopsy findings of the first and second filial generations of atomic bomb survivors

    Autopsy findings of 652 fetuses whose parents or one parent were exposed to the Atomic Bomb (F1) and 115 fetuses which had one or two grandparents exposed (F2) were compared with that of 8570 fetuses whose parents were not exposed (control). The F1 fetuses have been collected since 1963 and F2 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 F1 and F2. The malformations were cardiovascular, central nervous and urogenital system, quantitatively in that order, in both groups of F1 and F2. 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 F1 and F2. (author)

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

    Ariel Barreto Nogueira

    2012-12-01

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

  17. Causes of childhood deaths in Bangladesh: results of a nationwide verbal autopsy study.

    Baqui, A. H.; Black, R. E.; Arifeen, S. E.; Hill, K.; Mitra, S. N.; al Sabir, A.

    1998-01-01

    While knowledge of causes of deaths is important for health sector planning, little is known from conventional sources about the causes of deaths in Bangladesh. This is partly due to deficiencies in the registration system and partly because few deaths are attended by qualified physicians. The present study was undertaken to update the information available on causes of deaths among under-5-year-olds, taking advantage of advances in verbal autopsy methodology and of the national Bangladesh Demographic and Health Survey conducted in 1993-94. About 25% of the deaths were associated with acute lower respiratory infections (ALRI) and about 20% with diarrhoea. Neonatal tetanus and measles remained important causes of death, and drowning was a major cause for 1-4-year-olds. Research and programmes to enable mothers to identify ALRI cases, particularly pneumonia, and to encourage timely and appropriate care-seeking and strengthening of ALRI case management at the primary care facilities are important priorities. While promotion of oral rehydration for watery diarrhoea and antibiotic treatment for dysentery should continue, broader preventive interventions including provision of safe water and sanitation, and improvements in personal hygiene require more attention. Further intensification of immunization programmes and innovative experimental interventions to reduce childhood from drowning should be designed and tested. PMID:9648357

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

    Aramandla Ramesh

    2014-12-01

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

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.

    Full Text Available BACKGROUND: Aorto-arterial thrombosis is very often associated with atherosclerotic and/or aneurysmal changes. Thrombosis, unrelated to these changes is infrequent. AIMS: To evaluate the clinical presentation and aetiopathogenesis of aorto-arterial thrombosis, unrelated to atherosclerosis and aneurysms. SUBJECTS AND METHODS: A retrospective study of 30 autopsied cases of non-atherosclerotic and non-aneurysmal aorto-arterial thrombosis collected over a period of 14 years was carried out. RESULTS: There were 23 males and seven females and majority presented in the third to fourth decades of life with clinical features of acute abdomen or lower limb gangrene. Abdominal aorta as the site of thrombosis was observed in 46.5% cases. The causes were attributed to hypercoagulable states and changes in the aortic wall. No aetiology could be identified in 5 patients (16.6%. Associated tuberculosis was seen in six cases. CONCLUSIONS: Non-atherosclerotic aortic thrombosis is a heterogeneous group of disorders. Young and even elderly patients with symptoms related to abdominal ischaemia or peripheral vascular disease should be investigated thoroughly for hypercoagulable states and aortic pathology.

  1. Statistical studies on heart disease of the pathological autopsy cases in the Atomic Bomb Hospital

    Of 1230 autopsied cases in the Atomic Bomb Hospital and in the Red-Cross Hospital from 1956 to March, 1975, a statistical study was made on 118 cases in which primary or secondary heart disease had been found. The results are as follows. The incidence of myocardial infarction was 2.4 times higher in the group exposed to the atomic bomb within 2 km distance from the bombed area than that it was in the unexposed group. The incidence of acquired valvular disease was 4.1 times higher in the exposed group than in the unexposed group. From the standpoint of the incidence of myocardiosis, there was no difference between the groups. The incidence of pericarditis was 1.5 times higher in the exposed group than in the unexposed group. The incidence of cor pulmonale was 1.8 times higher in the exposed group than in the unexposed group. The incidence of other heart disease including congenital disease was, however, 1.6 times higher in the unexposed group than in the exposed group. The incidence of general heart disease was 1.7 times higher in the exposed group than in the unexposed group. The incidence of hypertrophy of the heart (more than 400 g) was 1.2 times higher in the exposed group than in the unexposed group. (Namekawa, K.)

  2. A hospital based autopsy study of 50 cases at combined military hospital (cmh), sialkot

    To analyze the pattern of deaths on autopsy carried out on Armed Forces personnel in CMH Sialkot. Study Design: Retrospective analytical study Place and Duration of Study: Combined Military Hospital Sialkot (CMH), from 2009 to 2012 Materials and Methods: In a total of fifty (50) cases detailed postmortems were carried out and gross features on external examination and different systemic examinations were recorded. Histopathology of various organs was done in all cases. Chemical and toxicological examination of various abdominal viscera was carried out in all sudden and suspicious deaths. Results: Ischemic Heart Disease (IHD) was most common cause of death (38%) followed by road traffic accidents (14%) and electrocution (8%). Sudden adult death syndrome accounted for 4 cases of deaths. Other causes were drowning, cerebral malaria, heat stroke, gunshot wounds, myocarditis, brain hemorrhage, meningitis and diabetic ketoacidosis. Most of these cases were young soldiers (n=30) followed by Non-Commissioned Officers (n=17). Conclusion: A large number of our young soldiers dying of heart problems is an alarming situation. Awareness among the troops of various risk factors is most important. Precautionary measures against preventable causes should be taken. (author)

    The Autopsy Tissue Program was begun in 1960. To date, tissues on 900 or more persons in 7 geographic regions have been collected and analyzed for plutonium content. The tissues generally consist of lung, liver, kidney, lymph, bone, and gonadal tissues for each individual. The original objective of the program was to determine the level of plutonium in human tissues due solely to fallout from weapons testing. The baseline thus established was to be used to evaluate future changes. From the first, this program was beset with chemical and statistical difficulties. Many factors whose effects were not recognized and not planned for were found later to be important. Privacy and ethical considerations hindered the gathering of adequate data. Since the chemists were looking for amounts of plutonium very close to background, possible contamination was a very real problem. Widely used chemical techniques introduced a host of statistical problems. The difficulties encountered touch on areas common to large data sets, unusual outlier detection methods minimum detection limits, problems with aliquot sizes, and time-trends in the data. The conclusions point out areas to which the biologists will have to devote much more careful attention than was believed.

    Full Text Available Background: Exhumation is a process by which the already buried dead body is taken out by digging under the law of the land. Most of exhumations are attended by non forensic hence the legal procedure of exhumation and meticulous examination of the dead body are lacking and literature is silent regarding it. Objective: To study exhumation process, digging time, depth of burial, posture of the body, human remains cause of death and interval between death and burial were studied. Materials & Methods: 18 cases of exhumation carried at Vijayapur district from 2003 to 2015 were studied. Results: Average digging time 56 minutes, average depth of burial 3.56 feet, posture of the body in 50% sitting and in 50% horizontal, in all cases expect one case skeleton remains were examined, cause of death found in 88.88% cases, average duration of burial 103 days. Interval between death and burial affects rate of decomposition. In 2 cases cause of death not found hence soil and decomposed soft tissues were preserved, duration of skeletinization to occur was 2 to 3 months. Conclusions: Exhumation is not a futile exercise and cause of death can be found in most of cases irrespective of duration of burial. Interval between the date and time of death to the date & time of burial is also an important factor which affect rate of decomposition. Always it is advantageous to hold exhumation & medico legal autopsy on the exhumed dead body or the remains by Forensic Medicine & Toxicology expert.

    In developing countries, the knowledge of the microorganisms causing fatal infections is critical and could help designing and implementing more effective preventive interventions and treatment guidelines. We aimed to develop and validate protocols for microbiological analysis in post-mortem samples obtained during minimally invasive autopsy (MIA) procedures and to assess their performance. Thirty MIAs performed in adults at Maputo Central Hospital in Southern Mozambique were included in the analysis. Microbiological tests included a universal screening for HIV, hepatitis B and C viruses, Plasmodium falciparum, and bacterial/fungal culture. In addition, a variety of molecular microbiology assays guided by the histological results were performed in blood, cerebrospinal fluid and a variety of tissue samples including liver, lung and central nervous system. The combination of culture-based methods together with molecular microbiological assays led to the identification of 17 out of 19 (89.5%) of the infectious deaths. Microorganisms identified included Mycobacterium tuberculosis, Toxoplasma gondii, Pneumocystis jiroveci, Cryptococcus neoformans, hepatitis B virus, human herpesvirus 8, cytomegalovirus, Streptococcus pneumoniae, Streptococcus dysgalactiae, Ryzopus oryzae, and Acinetobacter baumannii. The combination of classical cultures, serological tests and molecular assays performed in samples obtained through MIA allows the identification of most infectious agents causing death.

    Malaria is a lethal protozoan infection which is generally diagnosed antemortem and rarely diagnosed postmortem in a few cases. A fifty five year old, Turkish citizen male has been referred for autopsy. It has been found that he has gone abroad to work a month ago, however, quitted malaria prophylaxis before the intended end and brought into the emergency department in an unconscious state.Following quinine and clindamycin treatment with the initial diagnosis of cerebral malaria, the case was reported to have died due to his general condition got worsened at the end of the third day of therapy.Histopathological evaluation of postmortem tissues was revealed haphazardly arranged minor bleedings and central vascular necrotic foci in the cerebrum, cerebelum and brain stem; light brown pigment containing cells around vasculature; and pigment containing cells in the spleen and bone marrow. Cerebral malaria has a rapid course and is rare but one of the lethal complications of infections with Plasmodium. Although domestic malaria cases has been decreasing in our country, it should be kept in mind that the malaria infection can be seen in persons travelling abroad to high endemic malarial regions and an appropriate antimalarial prophylaxis should be recommended to those overseas travellers.

    The rudimentary horn is a rare developmental anomaly of the Müllerian duct. Ectopic pregnancy in the rudimentary horn is estimated to occur in one out of 76,000-150,000 pregnancies. A 30-year-old primigravida suddenly collapsed after 3 days of continuous abdominal pain. Emergency laparotomy revealed a massive intraperitoneal hemorrhage and fetal demise. The growth of the fetus after 19 weeks of gestation is believed to have caused the rudimentary horn rupture, thereby rapidly leading to hemorrhagic shock in the mother and ischemic death in the fetus. This is the first autopsy report on maternal death due to the rudimentary horn or other Müllerian duct anomalies, which emphasizes the need for forensic pathologists to consider this condition as a possible cause of unexpected death in fertile women. In addition, it is very important for clinicians to detect Müllerian duct anomalies by sonography during routine obstetric examinations, and promptly diagnose anomaly related ectopic pregnancies in women displaying symptoms of an acute abdomen, intraperitoneal hemorrhage, or shock in the emergency practice.

  8. Disseminated perivenous necrotizing encephalomyelitis in systemic lupus erythematosus: report of an autopsy case.

    Shintaku, M; Matsumoto, R

    1998-03-01

    The patient, a 22-year-old woman who had been treated for systemic lupus erythematosus (SLE) for 10 years, was hospitalized for arthralgia, melena, and difficulty in walking. CT examination of the brain showed grain-like high-density lesions scattered throughout the cerebral white matter and basal ganglia. At autopsy, multiple perivenous, well-demarcated foci of brownish discoloration were seen scattered throughout the cerebral white matter and basal ganglia. Histopathologically these lesions consisted of foci of coagulation necrosis surrounding the veins. The veins in the foci showed fibrous thickening of the walls, but there were no indications of vasculitis. At the periphery of the lesions, the axons were better preserved than their myelin sheaths. The neuropathological findings in the present case closely resemble those of acute disseminated (perivenous) encephalomyelitis, although an inflammatory cell infiltration had apparently already subsided. Although its pathogenesis remains unclear, this finding should not be regarded as an incidental complication but rather as a rare subtype of central nervous system lesion occurring with SLE.

    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).

    2015-03-01

    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. PMID:25573226

    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. PMID:18661140

  12. Understanding maternal deaths from the family's perspective: verbal autopsies in rural Tanzania.

    2014-09-01

    Maternal mortality rates in rural Tanzania are high. In preparation for the introduction of an intervention to reduce maternal deaths by distribution of misoprostol and erythromycin to women living in rural Rorya District, Mara Region, Tanzania, we conducted a limited verbal autopsy by surveying family members of women who died in childbirth in the previous five years. The purpose of this survey was to understand the circumstances surrounding these deaths. Thirty six family members were interviewed. The majority of the deaths occurred on the roadside as the women made their way to a health facility (23/36). Most of the women were delivered by a TBA (16/36) or family member (13/36). The majority of the family members attributed the death of their loved one to bleeding or retained placenta (32/36). Maternal deaths are common in this rural district of Tanzania because of long distances from the health facilities, difficulty finding transportation, costs of transport and hospital, and women's beliefs about being able to deliver at home and fear of medication. There is a need for increased education of women and their families about the benefits of childbirth in a healthcare facility attended by skilled providers. There is also a role for the community distribution of misoprostol to be used as an alternative uterotonic medication if a facility birth is not possible, as the rates of maternal death from hemorrhage are unacceptably high.

    In this study, we compared the clinicopathological findings of two autopsy cases of patients with calpainopathy (LGMD2A) from different families. The patient in case 1 was a 72-year-old man with a history of type 2 diabetes mellitus. He exhibited recent memory impairments from the age of 70. ECG revealed an incomplete right bundle branch block. A homozygous frameshift mutation c.1796dupA was found in the CAPN3 gene. Cause of death was respiratory insufficiency and heart failure. The patient in case 2 was a 70-year-old man with a history of hypertension. ECG revealed an incomplete right bundle branch block. A homozygous missense mutation c.1080G>C (p.Trp360Cys) in CAPN3 gene was identified. Cause of death was ischemic cardiomyopathy and systemic circulatory failure. In both cases, muscle pathology revealed severe dystrophic changes. In case 2, cardiac hypertrophy and old myocardial infarcts with stenosis of coronary arteries were observed. Histological examination of the sinoatrial node showed fatty infiltration with ischemic changes in case 2. In both cases, the patients' brains showed cerebral atrophy and well preserved neurons. Calpain 3 abnormality was correlated with skeletal muscle involvement. It should be considered that LGMD2A might be complicated by dysfunction of the cardiac conduction system. PMID:25200581

    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.

  16. Five years audit for presence of toxic agents/drug of abuse at autopsy

    Objective: To know the frequency of fatal poisoning in Peshawar regarding the toxic agents mostly involved and year wise percentage. To know the age group and the gender that is most vulnerable to fatal poisoning. Results: Poisoning was the cause of death in 1.48% of the total autopsies conducted during the five years. Males were more involved than the females, 90.38%. Suicidal poisoning was present in 17.30% of the total cases and accidental poisoning was found in 80.72% cases, while homicidal cases were 1.29% only. Diacetylmorphine (heroin) was the most commonly involved agent, 65.38%, of the total cases. The incidence of poisoning was more during the third and fourth decades of life. Conclusion: Diacetylmorphine (heroin) was the main causative agent involved in young males due to accidental over-dosage. Accidental and suicidal deaths should not be considered as inevitable. More elaborative studies are required in this area of recent research to adopt appropriate and adequate measures to save precious lives.(author)

    In clinical trials with oncolytic adenoviruses, there has been no mortality associated with treatment vectors. Likewise, in the Advanced Therapy Access Program (ATAP), where 290 patients were treated with 10 different viruses, no vector-related mortality was observed. However, as the patient population who received adenovirus treatments in ATAP represented heavily pretreated patients, often with very advanced disease, some patients died relatively soon after receiving their virus treatment mandating autopsy to investigate cause of death. Eleven such autopsies were performed and confirmed disease progression as the cause of death in each case. The regulatory requirement for investigating the safety of advanced therapy medical products presented a unique opportunity to study tissue samples collected as a routine part of the autopsies. Oncolytic adenoviral DNA was recovered in a wide range of tissues, including injected and noninjected tumors and various normal tissues, demonstrating the ability of the vector to disseminate through the vascular route. Furthermore, we recovered and cultured viable virus from samples of noninjected brain metastases of an intravenously treated patient, confirming that oncolytic adenovirus can reach tumors through the intravascular route. Data presented here give mechanistic insight into mode of action and biodistribution of oncolytic adenoviruses in cancer patients. PMID:26156245

  19. Truncus arteriosus communis in a midtrimester fetus: Comparison of prenatal ultrasound and MRI with postmortem MRI and autopsy

    Different techniques are used in fetal cardiology, and their accuracy has been demonstrated on several occasions. Color Doppler US has proved to be a reliable and valuable tool in the diagnosis of fetal cardiac abnormalities. Magnetic resonance imaging (MRI) of the fetal heart has, so far, played no role in prenatal diagnostics. We report on a truncus arteriosus communis diagnosed prenatally during a screening ultrasound at 22 weeks of gestation. In addition to real-time ultrasound and color Doppler echocardiography, fetal MRI was performed. Fetal echocardiography arose suspicion of a type I common trunk. Fetal MR showed solely a widened vessel coursing retrocardially and additionally an inhomogeneous fluid distribution of the lung not shown on prenatal US. After termination of pregnancy at 23 weeks of gestation, MR fetography and autopsy were performed, and both found a type II common trunk. MR autopsy of the heart was very reliable in this case and could be an alternative when fetal pathology is not available for different reasons. Postmortem MRI was also able to demonstrate the inhomogeneous fluid distribution in the lung, which was confirmed by autopsy. Fetal and postmortem MR was reliable in the detection of an inhomogeneous fluid distribution in the lung not shown on prenatal US, providing a relevant additional finding to US. Therefore, MRI should be used more often in fetal cardiology, although it still must be further developed. (orig.)

    2016-01-01

    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.

    2012-04-01

    This article describes a robust methodology using the combination of instrumental design (high matrix interface-HMI), sample dilution and internal standardization for the quantification of beryllium (Be) in various digested autopsy tissues using inductively coupled plasma mass spectrometry. The applicability of rhodium as a proper internal standard for Be was demonstrated in three types of biological matrices (i.e., femur, hair, lung tissues). Using HMI, it was possible to achieve instrumental detection limits and sensitivity of 0.6 ng L(-1) and 157 cps L ng(-1), respectively. Resilience to high salt matrices of the HMI setup was also highlighted using bone mimicking solution ([Ca(2+)] = 26 to 1,400 mg L(-1)), providing a 14-fold increase in tolerance and a 2.7-fold decrease in method detection limit compared to optimized experimental conditions obtained without the HMI configuration. Precision of the methodology to detect low levels of Be in autopsy samples was demonstrated using hair and blood certified reference materials. Be concentration ranging from 0.015 to 255 μg kg(-1) in autopsy samples obtained from the U.S. Transuranium and Uranium Registries were measured using the methodology presented. PMID:22349407

  3. Prevalence rate of thyroid diseases among autopsy cases of the atomic bomb survivors in Hiroshima, 1951-1985

    To examine the radiogenic risk of latent thyroid cancer, thyroid adenoma, colloid/adenomatous goiter and chronic thyroiditis, the date for 3821 subjects collected in the course of autopsies of atomic bomb survivors in Hiroshima from 1951 to 1985 by the Radiation Effects Research Foundation (RERF) were analyzed using a logistic model. About 80% of the autopsies were performed at RERF and the remainder at local hospitals. The frequencies of the above diseases were not associated with whether the underlying cause of death was cancer. However, note that our results may be influenced by potentially biasing factors associated with autopsy selection. The relative frequency of latent thyroid cancer (greatest dimension ≤1.5 cm but detectable on a routine microscopic slide of the thyroid gland) increased as the radiation dose increased and was about 1.4-fold greater at 1 Gy than in the 0-Gy dose group. The relative occurrence of thyroid adenoma also increased as radiation dose increased, and was about 1.5-fold greater at 1 Gy than in the 0-Gy dose group. Sex, age at the time of the bombing or period of observation did not significantly modify the radiogenic risks for thyroid adenoma or latent thyroid cancer. No statistically significant association was found between radiation exposure and the rates of colloid/adenomatous goiter and chronic thyroiditis. The possible late effect of atomic bomb radiation on the frequency of benign thyroid diseases is discussed on the basis of these data. 38 refs., 2 figs., 5 tabs

    Full Text Available OBJETIVO: Validar las entrevistas verbales a parientes y allegados para determinar las causas de la mortinatalidad que utiliza la Organización Mundial de la Salud (OMS), empleando el diagnóstico hospitalario de las causas subyacentes a la mortinatalidad («criterio de referencia») y comparar la propo [...] rción de mortinatos atribuidos a determinadas causas específicas, a través de la valoración del hospital, en comparación con los resultados de las investigaciones verbales. MÉTODOS: Realizamos un estudio prospectivo de todos los mortinatos que nacieron en un hospital de Chandigarh (India) entre el 15 de abril de 2006 y el 31 de marzo de 2008 y cuya causa de defunción se diagnosticó dentro de un plazo de 2 días. Todas las madres debían encontrarse como mínimo en la semana 24 de gestación y vivir dentro de un radio de 100 km del hospital. Para las entrevistas verbales, los trabajadores en el terreno visitaron a las madres entre las 4 y las 6 semanas posteriores a la mortinatalidad. Dos obstetras independientes revisaron los resultados de las autopsias y, en caso de desacuerdo, se solicitó la participación de un tercer experto. Se comparó la frecuencia de las causas de la mortinatalidad, según lo establecido por la valoración hospitalaria y por las investigaciones verbales. RESULTADOS: Tanto la valoración hospitalaria como la entrevista verbal coincidieron en cuáles eran las cinco causas de mortinatalidad más frecuentes: preeclampsia (30%), hemorragia prenatal (16%), enfermedad subyacente de la madre (12%), malformaciones congénitas (12%) y complicaciones obstétricas (10%). La precisión general del diagnóstico mediante investigación verbal, en comparación con el diagnóstico basado en la información hospitalaria para las cinco causas más frecuentes de mortinatalidad, fue del 64%. Las áreas bajo la curva de eficacia diagnóstica (ROC) fueron: para las malformaciones congénitas, 0,91 (intervalo de confianza del 95%, IC: 0,83-0,97); enfermedad pre-gestacional de la madre, 0,75 (95%, IC: 0,65-0,84); preeclampsia, 0,76 (95%, IC: 0,69-0,81); hemorragia prenatal, 0,76 (95%, IC: 0,67-0,84) y complicaciones obstétricas, 0,82 (95%, CI: 0,71-0,93). CONCLUSION: La herramienta de investigación verbal de la mortinatalidad que emplea la OMS puede ofrecer unas estimaciones razonablemente aceptables de las causas subyacentes más frecuentes a la mortinatalidad en los ámbitos con recursos limitados, en los que la causa de mortinatalidad pueda no estar certificada por un médico. Abstract in english OBJECTIVE: To validate the verbal autopsy tool for stillbirths of the World Health Organization (WHO) by using hospital diagnosis of the underlying cause of stillbirth (the gold standard) and to compare the fraction of stillbirths attributed to various specific causes through hospital assessment ver [...] sus verbal autopsy. METHODS: In a hospital in Chandigarh, we prospectively studied all stillbirths occurring from 15 April 2006 to 31 March 2008 whose cause was diagnosed within 2 days. All mothers had to be at least 24 weeks pregnant and live within 100 km of the hospital. For verbal autopsy, field workers visited mothers 4 to 6 weeks after the stillbirth. Autopsy results were reviewed by two independent obstetricians and disagreements were resolved by engaging a third expert. Causes of stillbirths as determined by hospital assessment and verbal autopsy were compared in frequency. FINDINGS: Hospital assessment and verbal autopsy yielded the same top five underlying causes of stillbirth: pregnancy-induced hypertension (30%), antepartum haemorrhage (16%), underlying maternal illness (12%), congenital malformations (12%) and obstetric complications (10%). Overall diagnostic accuracy of verbal autopsy diagnosis versus hospital-based diagnosis for all five top causes of stillbirth was 64%. The areas under the receiver operator characteristic curve (ROC) were, for congenital malformations, 0.91 (95% confidence interval, CI: 0.83-0.97); pre-gestational maternal illness, 0.75 (95% CI: 0.65-0.84);

    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 study is the information on a wide range of informative alcohol biomarkers, several of which have not been used previously in this sort of post-mortem research study. We have demonstrated, for the first time, the epidemiological value and validity of these novel alcohol biomarkers in post-mortem samples.

    Full Text Available Introduction. The forming of the blood vessels network configuration at the base of the brain and interconnecting of blood vessels during the embryogenesis is directly related to the phylogenetic development of the brain and brain structures. A blood vessel configuration at the brain base, in the form of a ring or a hexagon, stands in direct relation to the perfusion needs of certain parts of the brain during its primary differentiation. The aim of this paper was to determine the incidence of certain blood vessel configurations at the base of the brain and understanding their symmetry or asymmetry. Methods. Analysis of the blood vessels at the base of the brain was performed on the autopsied subjects. The object of observation was the anterior segment of the circle of Willis consisting of C1- a. carotis interna (ICA, above a. communicaus posterior (PcoA, the segment A1 a. cerebri anterior (ACA from a. carotis interna bifurcation to the a. communicans anterior (AcoA and a. communicans anterior itself, as well as the posterior segment consisting of PcoA and the segment P1 - a. cerebri posterior (PCA from the a. basilaris bifurcation to the PcoA. For the purpose of grouping the findings, the four basic configuration types of the circle of Willis were identified based on its symmetry or asymmetry. Type-A (symmetric circle of Willis, type-B (asymmetric circle of Willis' due to the unilateral hypoplastic A1-ACA; type-C (symmetric circle of Willis with bilateral symmetric changes on PcoA and type-D (asymmetric circle of Willis due to the asymmetric changes on PcoA. Results. Autopsy was performed on 56 corpses. A total of 41 (73.2% subjects were recorded with a symmetric configuration of the circle of Willis', of which 27 (48.2% subjects had type A and 14 (25% type C. The asymmetric configuration was present in 15 (26.8% subjects, of whom 9 (16% had type B and 6 (10.8% type D. The symmetric Willis group (73.2% did not have a homogeneous finding that would fit into the schematic presentation of the symmetric type A and type C. A total of 17 (30.4% findings were classified in this group of the so-called conditionally symmetric configurations. In all the cases, type B (16% had unilaterally reduced diameter A1 and hyperplastic AcoA. Conclusion. The presence of asymmetric Willis configuration in 26.8% of the cases, which makes up more than one fourth, indicates that the asymmetric configurations do not represent a pathological form of connecting the blood vessels at the base of the brain, but rather one aspect of its adaptation. The forming of the basic types of configurations of the circle of Willis is associated with a tendency toward certain types of hemodynamic disorders and more frequent pathological changes in places of reduced resistance.

    Evidence from patients with amnesia suggests that recognition memory span tasks engage both long-term memory (i.e., secondary memory) processes mediated by the diencephalic-medial temporal lobe memory system and working memory processes mediated by fronto-striatal systems. Thus, the recognition memory span task may be particularly effective for detecting memory deficits in disorders that disrupt both memory systems. The presence of unique pathology in fronto-striatal circuits in Dementia with Lewy Bodies (DLB) compared to AD suggests that performance on the recognition memory span task might be differentially affected in the two disorders even though they have quantitatively similar deficits in secondary memory. In the present study, patients with autopsy-confirmed DLB or AD, and Normal Control (NC) participants, were tested on separate recognition memory span tasks that required them to retain increasing amounts of verbal, spatial, or visual object (i.e., faces) information across trials. Results showed that recognition memory spans for verbal and spatial stimuli, but not face stimuli, were lower in patients with DLB than in those with AD, and more impaired relative to NC performance. This was despite similar deficits in the two patient groups on independent measures of secondary memory such as the total number of words recalled from long-term storage on the Buschke Selective Reminding Test. The disproportionate vulnerability of recognition memory span task performance in DLB compared to AD may be due to greater fronto-striatal involvement in DLB and a corresponding decrement in cooperative interaction between working memory and secondary memory processes. Assessment of recognition memory span may contribute to the ability to distinguish between DLB and AD relatively early in the course of disease. PMID:26184443

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

    2011-12-01

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

  10. An autopsy case of a giant aneurysm of the anterior communicating artery

    A 64-year-old female was admitted to our hospital on 8, July, 1980 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. The results of the neuroradiological examinations were as follows. 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. A small high-density region was enhanced as an island within it by means of a Conray infusion. 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. Clinically, rerupture was not verified. An autopsy specimen revealed that a giant aneurysm (6 x 5 x 4 cm in size) arising from the anterior communicating artery occupied the intra ventricular space, the anterior horn of the lateral ventricle, and the right thalamic region. Also, there was a large berry aneurysm (2 x 1.7 x 1.5 cm in size) 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.

    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. PMID:26807995

    2008-08-01

    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.

    2014-05-01

    Additional head of the biceps brachii (AHBB) has been reported in different population groups with a frequency of 1-25%. The purpose of this study was to determine the incidence and morphologic expression of the AHBB as determined in a sample of the Colombian population. An exploration was conducted with 106 arms corresponding to unclaimed corpses autopsied at Institute of Legal and Forensic Medicine of Bucaramanga, Colombia. Using medial incision involvingskin, subcutaneous tissue, and brachial fascia, the heads of the biceps and their innervating branches were visualised. One AHBB was observed in 21 (19.8%) of the arms evaluated, with non-significant difference (p = 0.568) per side of presentation: 11 (52.4%) cases on the right side and 10 (47.6%) on the left side. All AHBBs were originated in the infero-medial segment of the humerus, with a mean thickness of 17.8 ± 6.8 mm. In 4 (19%) cases the fascicle was thin, less than 10 mm; in 7 (33.3%) cases it was of medium thickness, between 11 and 20 mm, whereas in 47.6% it was longer than 20 mm. The length of the AHBB was 118.3 ± 26.8 mm; its motor point supplied by the musculocutaneous nerve was located at 101.3 ± 20.9 mm of the bi-epicondylar line. The incidence of AHBB in this study is located at the upper segment of what has been reportedin the literature and could be a morphologic trait of the Colombian population; in agreement with prior studies, the origin was the infero-medial surface of the humerus.

    2014-01-01

    The incidence of median-ulnar communication in the forearm presents variability in different population groups. The aim of this study was to determine the incidence and morphologic expression of the median-ulnar communication in a sample of the Colombian population. One hundred and eight forearms of autopsy material at the National Institute of Forensic Medicine of Bucaramanga, Colombia were studied. Using an approach of the flexor compartment of forearm the median and ulnar nerves were dissected and the communications between these two structures were characterized. The communicating branch occurred in 28 (25.9%) forearms. It occurred unilaterally in 12 specimens and bilaterally in 8, with statistically significant difference (P=0.01). The communication between the anterior interosseous and ulnar nerves was most frequent, observed in 13 (46.4%) forearms. The length of the communicating branch was 56.9 +/- 8.3 mm. The distance of the proximal and distal points of the communicating branch to the bi- epicondylar line was 59.6 +/- 15.4 mm and 102.7 +/- 23.5 mm respectively. The length of the forearm was 269.8 +/- 15.9 mm. A projection of the communicating branch from the upper third to the midthird of the forearm was observed. The incidence of the median-ulnar communication in the present study is in the high rank reported in the literature; there is an agreement with prior studies in finding more numerous communicating branches in the right forearm. The median-ulnar communication should be taken into account for surgical approach of the forearm. PMID:26749683

  15. Demographic, etiological, and histological pulmonary analysis of patients with acute respiratory failure: a study of 19 years of autopsies

    Alexandre de Matos Soeiro

    2011-01-01

    Full Text Available INTRODUCTION: Acute respiratory failure has been one of the most important causes of death in intensive care units, and certain aspects of its pulmonary pathology are currently unknown. OBJECTIVES: The objective was to describe the demographic data, etiology, and pulmonary histopathological findings of different diseases in the autopsies of patients with acute respiratory failure. METHOD: Autopsies of 4,710 patients with acute respiratory failure from 1990 to 2008 were reviewed, and the following data were obtained: age, sex, and major associated diseases. The pulmonary histopathology was categorized as diffuse alveolar damage, pulmonary edema, alveolar hemorrhage, and lymphoplasmacytic interstitial pneumonia. The odds ratio of the concordance between the major associated diseases and specific autopsy findings was calculated using logistic regression. RESULTS: Bacterial bronchopneumonia was present in 33.9% of the cases and cancer in 28.1%. The pulmonary histopathology showed diffuse alveolar damage in 40.7% (1,917 of the cases. A multivariate analysis showed a significant and powerful association between diffuse alveolar damage and bronchopneumonia, HIV/AIDS, sepsis, and septic shock, between liver cirrhosis and pulmonary embolism, between pulmonary edema and acute myocardial infarction, between dilated cardiomyopathy and cancer, between alveolar hemorrhage and bronchopneumonia and pulmonary embolism, and between lymphoplasmacytic interstitial pneumonia and HIV/ AIDS and liver cirrhosis. CONCLUSIONS: Bronchopneumonia was the most common diagnosis in these cases. The most prevalent pulmonary histopathological pattern was diffuse alveolar damage, which was associated with different inflammatory conditions. Further studies are necessary to elucidate the complete pathophysiological mechanisms involved with each disease and the development of acute respiratory failure.

  16. Is necropsy obsolete - An audit of the clinical autopsy over six decades: A study from Indian sub continent

    Nikhil Moorchung

    2013-01-01

    Full Text Available Introduction: Several studies have documented a decrease in the autopsy rate. This study was taken up to analyse the cause of mortality, the discrepancies between the ante mortem and post mortem diagnosis and the discrepancies between diagnoses according to the type of the disease over a period of six decades. Materials and Methods: Autopsy reports and medical records were retrospectively analyzed over a 63 year period from 1947 to 2010. Results: In our study, there was a steady increase in the percentage of neoplastic cases from 1947 to 1994 after which there has been a significant drop. The cases dying due to infection has also shown a steady decline over the years until 1994. After 1994, there has been a significant increase in the deaths until 2010 (p < 0.05. Death due to cardiac causes has shown an increase until 1962 which has been followed by a steady decline. There has been a sudden rise in the number of cases dying due to renal causes between 1994 and 2000 (p < 0.05. There has been a statistically significant decrease in the discrepancies between the ante mortem and the post mortem diagnosis over the years. Discussion: This study shows that therapeutic and preventive measures correctly instituted have significantly reduce the mortality, particularly with reference to cardiac and infectious causes. The discrepancy between antemortem and post-mortem diagnosis in 2010 is still very high at 9.30 percent. The autopsy will continue to remain relevant especially in elucidating the molecular cause of disease.

    2015-01-01

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

  18. [Tumors of the central nervous system in biopsy and autopsy material. 7th communication: neurinomas and neurofibromatoses with CNS involvement].

    Schneider, J; Warzok, R; Schreiber, D; Güthert, H

    1983-01-01

    In 1,491 autopsy cases with CNS tumors observed at the Pathological Institute of the Medical Academy of Erfurt in the period from 1953 to 1976 (54,946 autopsies) 72 cases (4.8%) with neurinomas were found. They comprise 67 solitary neurinomas, 1 bilateral acoustic neurinoma without other signs of neurofibromatosis, and 4 cases of neurofibromatosis with neurinomas of the CNS. Among the 68 cases with CNS neurinomas (neurofibromatoses excluded) 87% were acoustic neurinomas, 12% spinal tumors, and 1 case was located in the trigeminal nerve. In 60 (88%) of these 68 cases, the neurinoma was operated upon or clinically diagnosed, resp. The diameter of 18 (26%) neurinomas of the autopsy material was larger than 5 cm. Patients in the 6th decennium predominated in this series. The sex distribution revealed a preponderance of females over males (3:1). In 3 cases further CNS tumors (ependymoma, glioblastoma, meningioma) were found. Additionally, 3 cases had carcinomas of different localization (Table 5). Following tumors were seen in 9 cases of Morbus Recklinghausen with CNS involvement: 4 cases with multiple neurinomas, 3 meningiomas, 1 astrocytoma, 2 glioses and 1 angiomatous malformation (Table 6). Among 1,670 CNS tumors in biopsy material, 144 (8.6%) were neurinomas. 60% of them were located in the nervus acusticus, 40% spinally, mainly in the thoracic region. The 6th decennium was most affected, and females were more frequent than males (2:1) in our material. Nearly all CNS neurinomas were benign. Only 1 spinal tumors was classified as a malignant neurinoma. 2 of the 9 cases with Morbus Recklinghausen had malignant neurogenic tumors (neurofibrosarcomas). PMID:6410615

    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 deaths, 2 other causes of death), 4 ground-glass opacities (3 sudden and unexplained deaths and 1 other) and 11 mixed (11 sudden and unexplained deaths). Types of opacities were not significantly associated with causes of death or resuscitation attempt. Conclusion: Atelectasis is very common in sudden and unexplained death of infants. Bilateral diffuse mixed opacity was observed only in sudden and unexplained deaths. Bilateral diffuse pure consolidation or ground-glass opacity was also observed in other causes of death.

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

    Raymond A. Aborigo

    2013-09-01

    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 need to be given greater consideration in the collection of cause of death data, and this can be achieved through the establishment of processes that allow active engagement with communities, authorities of civil registrations, and Institutional Review Boards to take greater account of local contexts.

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

    Morild Inge

    2007-10-01

    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 necessary to evaluate the impact on Hg in the brain of various sources of exposure, in particular, dental amalgam exposure.

    A fatal accident is reported in which a small single-engine light airplane crashed. The airplane carried two persons in the front seats, both of whom possessed valid pilot certificates. Both victims were subject to autopsy, including post-mortem computed tomography scanning (PMCT) prior to the...... autopsy. The autopsies showed massive destruction to the bodies of the two victims but did not identify any signs of acute or chronic medical conditions that could explain loss of control of the airplane. PMCT, histological examination, and forensic chemical analysis also failed to identify an explanation...... for the crash. A detailed review of an airplane identical to the crashed airplane was performed in collaboration with the Danish Accident Investigation Board and the Danish National Police, National Centre of Forensic Services. The injuries were described using the abbreviated injury scale, the injury...

  5. An autopsy case of acute myelocytic leukemia preceded by hemopoietic dysplasia found in an atomic bomb survivor

    An autopsy case of acute myelocytic leukemia preceded by hemopoietic dysplasia, presumably on a sequela to the atomic bomb in Hiroshima is reported. On admission, severe anemia and thrombocytosis were found and the bone marrow aspiration showed myeloid hyperplasia without definite maturation arrest. Mild to moderate eosinophilia and basophilia continued during the course of the disease, accompaning mild monocytosis 2 years later. Furthermore, he had the radical operation for the early gastric cancer in this preleukemic stage. After the administration of methenolone acetate (25 mg/day), severe anemia has dramatically improved, but leukocytosis with profound monocytosis persisted, and subsequently acute myelocytic leukemia developed. He died from an intracerebral bleeding due to an accidental trauma on the head. Autopsy findings disclosed the systemic leukemic infiltration. Repeated chromosome analyses revealed the mosaic karyotype of 46, XY/45, XY, -16 on admission, but it was 46, XY/46, XY, del (8) (p 12) in the overt leukemic phase. The granulopoietic colony forming capacity of bone marrow cells was already low one year before the onset of overt leukemia. This finding suggested that the existence of an abnormal clone could be predictable. In addition, the possible causative effect of the exposure to the atomic bomb in leukemogenesis in this case is discussed. (author)

    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.)

  7. The problem with medical research on tissue and organ samples taken in connection with forensic autopsies in France.

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

    2016-02-01

    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.

  8. An autopsy study of histopathological changes in the urinary bladder transitional epithelium of atomic bomb survivors, 1960 - 1983

    From the ABCC-RERF Life Span Study extended sample, there were 4,499 cases in the Pathology Study sample of atomic bomb survivors who had come to autopsy in the period 1960 - 83. Among 370 subjects who were heavily exposed with an estimated dose (T65D) of 100 rad or more, 72 (about 20 %) of them, whose urinary bladder epithelia had been preserved satisfactorily to suit the purpose of this study, were sampled as the index group. An equal number of control subjects were selected from the unexposed group individually, matched with the index cases by city, sex, age at death, and year of death. However, cases with marked epithelial autolysis and those pathologically diagnosed as urinary bladder cancer were previously excluded from both the index group and control subjects. These 72 pairs of autopsy cases were pathologically studied for the presence or absence of epithelial lesions of the urinary bladder, namely, hyperplasia, dysplasia and carcinoma-in-situ, and the frequencies of appearance of these lesions were compared statistically by χ2 test based on a case-control study design. Carcinoma-in-situ and severe dysplasia were detected in neither the index cases nor the control cases. The risk was relatively higher in the index group than in the control subjects for both hyperplasia and dysplasia (mild and moderate), in particular the relative risk of papillary hyperplasia being about 4.0, but as the total number of cases were small, this was not statistically significant.

    2013-12-01

    To test the hypothesis that Alzheimer disease (AD) is a clinical and pathologic continuum between normal aging and end-stage dementia, we selected a convenience sample of subjects from the National Alzheimer Coordinating Center 2005 to 2012 autopsy cohort (n = 2,083) with the last clinical evaluation within 2 years before autopsy and no other primary neuropathologic diagnosis. Demographic and neuropathologic characteristics were correlated with the Clinical Dementia Rating-Sum of Boxes in the 835 subjects meeting these criteria. Both neuritic plaques and neurofibrillary tangles independently predicted Clinical Dementia Rating-Sum of Boxes. Severe small-vessel disease, severe amyloid angiopathy, and hippocampal sclerosis were also independently associated with the degree of cognitive impairment. By contrast, education was a strong independent protective factor against cognitive deficits. The cause of mild to moderate dementia remained uncertain in 14% of the patients. Inverse probability weighting suggests the generalizability of these results to nonautopsied cohorts. These data indicate that plaques and tangles independently contribute to cognitive impairment, that concurrent vascular disease strongly correlates with cognitive dysfunction even in a sample selected to represent the AD pathologic continuum, and that education further modifies clinical expression. Thus, multiple concomitant etiologies of brain damage and premorbid characteristics contribute to the uncertainty of AD clinicopathologic correlations based only on tangles and plaques.

    2006-01-01

    Pediatric developmental and genetic renal lesions are a known cause of mortality in the perinatal/neonatal period. These lesions are associated with a wide range of extrarenal congenital malformations that influence the outcome of the patients. In this autopsy study, we have analyzed the spectrum of pediatric developmental and genetic renal lesions and their associated congenital malformations. A total of 4,099 autopsies (20 weeks of gestation to 1 year of life) were reviewed, of which 158 cases (3.85%) of pediatric developmental (143 cases) and genetic renal lesions (15 cases) were found. Autosomal recessive polycystic kidney disease was the commonest genetic lesion. Primitive ducts with cuffing of immature mesenchyme--the sine qua non of renal dysplasia--was found in all cases of dysplasia. Associated congenital malformations were seen in all cases and thus a thorough search for them is mandatory. Ductal plate malformation was found in all cases of autosomal recessive polycystic kidney disease and in 1 case of bilateral multicystic dysplasia. PMID:16754487

    2015-06-01

    The goal of this study was to assess whether epicardial and paracardial adipose tissue volumes, as determined by computed tomography (CT), correlate with coronary artery stenosis as determined by autopsy. The postmortem CT data and autopsy findings of 116 adult human decedents were retrospectively compared. Subjects were classified into three groups according to their degree of coronary artery stenosis: ≥50, segmentation after threshold based masking. In addition, epicardial adipose tissue thickness was measured using a caliper. All three parameters (thickness of epicardial fat and volumes of both epicardial and paracardial fat) were compared among the three groups and correlated with the degree of coronary artery stenosis. The group with no coronary artery stenosis showed the lowest mean values of epicardial adipose tissue volume, while the coronary artery stenosis ≥50 % group showed the highest volume. All measured variables (thickness of epicardial fat and volumes of both epicardial and paracardial fat) correlated significantly with the grade of coronary artery stenosis, even after controlling for BMI, however, epicardial adipose tissue volume exhibited the strongest correlation. This study reveals that there is an association between the degree of coronary artery stenosis and the amount of epicardial fat tissue: The larger the volume of epicardial fat, the higher the degree of coronary artery stenosis.

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

    Luciano Pamplona de Góes Cavalcanti

    2015-12-01

    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.

    2014-10-01

    Full Text Available Objective: To estimate and evaluate the cause-of-death structure and disease-specific mortality rates in a rural area of The Gambia as determined using the InterVA-4 model. Design: Deaths and person-years of observation were determined by age group for the population of the Farafenni Health and Demographic Surveillance area from January 1998 to December 2007. Causes of death were determined by verbal autopsy (VA using the InterVA-4 model and ICD-10 disease classification. Assigned causes of death were classified into six broad groups: infectious and parasitic diseases; cancers; other non-communicable diseases; neonatal; maternal; and external causes. Poisson regression was used to estimate age and disease-specific mortality rates, and likelihood ratio tests were used to determine statistical significance. Results: A total of 3,203 deaths were recorded and VA administered for 2,275 (71%. All-age mortality declined from 15 per 1,000 person-years in 1998–2001 to 8 per 1,000 person-years in 2005–2007. Children aged 1–4 years registered the most marked (74% decline from 27 to 7 per 1,000 person-years. Communicable diseases accounted for half (49.9% of the deaths in all age groups, dominated by acute respiratory infections (ARI (13.7%, malaria (12.9% and pulmonary tuberculosis (10.2%. The leading causes of death among infants were ARI (5.59 per 1,000 person-years [95% CI: 4.38–7.15] and malaria (4.11 per 1,000 person-years [95% CI: 3.09–5.47]. Mortality rates in children aged 1–4 years were 3.06 per 1,000 person-years (95% CI: 2.58–3.63 for malaria, and 1.05 per 1,000 person-years (95% CI: 0.79–1.41 for ARI. The HIV-related mortality rate in this age group was 1.17 per 1,000 person-years (95% CI: 0.89–1.54. Pulmonary tuberculosis and communicable diseases other than malaria, HIV/AIDS and ARI were the main killers of adults aged 15 years and over. Stroke-related mortality increased to become the leading cause of death among the elderly aged 60 years or more in 2005–2007. Conclusions: Mortality in the Farafenni HDSS area was dominated by communicable diseases. Malaria and ARI were the leading causes of death in the general population. In addition to these, diarrhoeal disease was a particularly important cause of death among children under 5 years of age, as was pulmonary tuberculosis among adults aged 15 years and above.

  16. Remodeling of the pulmonary artery induced by metastatic gastric carcinoma: a histopathological analysis of 51 autopsy cases

    Gastric carcinoma remains the second commonest cause of cancer deaths worldwide. Presence of the carcinoma cell in the pulmonary artery is serious condition that might cause remodeling of the pulmonary artery. The present study conducted detailed histopathological analyses to elucidate how gastric carcinoma cells may affect the structure and hemodynamics of pulmonary arteries. Remodeling of the pulmonary artery was assessed based on measurements of arterial diameters and stenosis rates from the autopsies, and their correlation were also validated. We additionally calculated 95 percent confidential intervals (CIs) for the rate of stenosis in groups of pulmonary arteries of different caliber zones (under 100, 100 to 300, and over 300 micrometer). The right ventricular thickness was measured and examined whether it correlated with the rate of pulmonary arterial stenosis. A total of 4612 autopsy cases were recorded at our institute, among which 168 had gastric carcinoma. Finally, 51 cases of the gastric carcinoma were employed for the study which had carcinoma cells in the lumen of the pulmonary artery. The mean right ventricular wall thickness of these cases was 3.14 mm. There were significant positive associations between the rates of pulmonary arterial stenosis and right ventricular thickness from pulmonary arteries of diameter under 100, 100 to 300, and over 300 micrometer. In these zones, 31, 31, and 33 cases had rates of pulmonary arterial stenosis that were below the lower limit of the 95 percent CI values, respectively. On the other hand, among cases with significant pulmonary stenosis, 17 of 18 cases with stenosis in the over 300 micrometer zone involved pulmonary arteries of both in the under 100 and 100 to 300 micrometer zones. One-third of autopsy with advanced gastric carcinoma had carcinoma cells in lumen of pulmonary artery, but implantation and proliferation may be essential to induce intimal thickening that causes an increasing of pulmonary arterial pressure, because our study revealed a significant positive association between the rate of pulmonary arterial stenosis and right ventricular thickness. In addition, diffuse type gastric carcinoma may be apt to cause the remodeling of the pulmonary artery

  19. A state-of-the-art pipeline for postmortem CT and MRI visualization: from data acquisition to interactive image interpretation at autopsy

    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

    The presence of tissue cysts of Toxoplasma gondii has only poorly been investigated in autopsy series. We determined the presence of T. gondii cysts in a series of 51 autopsies in a public hospital using immunohistochemistry of brain and heart tissues. The association of tissue cysts with the general characteristics of the autopsy cases was also investigated. Of the 51 cases studied, five (9.8%) were positive by immunohistochemistry for T. gondii cysts in the brain. None of the heart specimens was positive for T. gondii cysts. The presence of T. gondii cysts in brains did not vary with age, sex, birthplace, residence, education, occupation, or the presence of pathology in the brain. In contrast, multivariate analysis showed that the presence of T. gondii cysts was associated with undernourishment (OR = 33.90; 95% CI: 2.82–406.32; P = 0.005). We demonstrated cerebral T. gondii cysts in an autopsy series in Durango City, Mexico. Results suggest that T. gondii can be more readily found in brain than in heart of infected individuals. This is the first report of an association between the presence of T. gondii in brains and undernourishment. PMID:26185682

  1. Mononeuritis multiplex due to thrombotic ischemia of primary antiphospholipid antibody syndrome without vasculitis: an autopsy case report.

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

    2015-12-23

    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. PMID:26511022

  2. A double-suicide autopsy case of potassium poisoning by intravenous administration of potassium aspartate after intake of some psychopharmaceuticals.

    Watanabe, K; Hasegawa, K; Suzuki, O

    2011-07-01

    We report a curious double-suicide autopsy case of both male and female who died of potassium poisoning by intravenous administration of concentrated potassium aspartate solution. The plasma concentrations of potassium of the male and female subjects were as high as 49.7 and 62.8 mEq/L, respectively. In addition to the high concentrations of potassium, toxic levels of phenobarbital, promethazine and chlorpromazine, and relatively low levels of etizolam and brotizolam were also detected from whole blood and urine specimens of both cadavers. Twenty empty plastic bottles (10-mL capacity) labeled 'ASPARA® Potassium Injection 10 mEq' were found at the suicide spot. To our knowledge, this is the first description for suicidal death by potassium aspartate; in all of the previous literature, they used potassium chloride intravenously or per os. PMID:20670988

  3. Significance of fibrotic bands in utero - Amniotic band sequence with limb body wall complex: A rare case of fetal autopsy

    P Lekshmi Devi

    2015-01-01

    Full Text Available Amniotic band sequence (ABS includes a wide spectrum of abnormalities resulting from entrapment of various fetal parts from a disrupted amnion, ranging from a mere constriction ring affecting a finger to a fatal form called limb body wall complex (LBWC. Reported cases of ABS with LBWC are very few. The spectrum of anomalies depends on which part gets entrapped and at what point of gestation. Hence, the clinical presentation can be extremely variable. Early detection of such cases using sonology is really challenging due to the small size of the fibrotic bands. Here, we present a case of amniotic band syndrome with LBWC in a fetus at 24 weeks of gestation, which was referred for an autopsy. The fetus also showed scoliosis, gastroschisis, lumbosacral meningocele, congenital talipes equinovarus, and cleft palate, thus having features of placenta cranial and placenta abdominal phenotype which is very rare.

  4. An autopsy case of hemiconvulsion-hemiplegia-epilepsy syndrome manifesting as cerebral hemiatrophy in an elderly man.

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

    2015-12-01

    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-?-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.

    2012-09-01

    Full Text Available We set out to investigate suicide among women in a post-conflict context in Northern Uganda using qualitative psychological autopsy interviews. Three to five relatives and friends for each of the three suicides recruited were interviewed (N=11. Through interpretative phenomenological analysis (IPA we found that the women all had been through traumatic experiences attributable to the protracted war/conflict between the rebel groups and Ugandan Government armed forces. Nevertheless, the decision of self-inflicted death seemed to have been due to a combination of unpleasant experiences/events that prevailed within the last 3 months prior to the suicide. These experiences are summarized in two broad themes: No control in life and No care. Changes in the traditional gender roles, men's quest for their lost masculinity, and women's attempt to fight for their rights that was perceived as a cultural transgression contributed to the women's suicides.

    2015-06-01

    In 2011, Save the Children India launched a project for the disadvantaged population of Rajasthan, Bihar and Odisha. As a baseline activity, neonatal deaths during January-December 2012 were investigated using modified verbal autopsy tool in six sub-district-level administrative units (blocks) adopting 30-cluster sample survey approach. Our study reported a total of 189 neonatal deaths of which 50% occurred at home and 39% happened on Day 1. About half of the deaths occurred in blocks from Bihar. High number of neonatal deaths belonged to households that were below poverty line (64%) and other disadvantaged classes (46%); among mothers who were illiterate (65%), <20 years of age (54%) and during their first-order births (36%). Birth asphyxia was a major cause of neonatal deaths across all blocks. These findings indicate need for easy and early access to transport services, specialized neonatal care and advocacy targeted towards increasing community awareness. PMID:25825343

  7. An autopsy case of progressive generalized muscle atrophy over 14 years due to post-polio syndrome.

    Oki, Ryosuke; Uchino, Akiko; Izumi, Yuishin; Ogawa, Hirohisa; Murayama, Shigeo; Kaji, Ryuji

    2016-01-29

    We report the case of a 72-year-old man who had contracted acute paralytic poliomyelitis in his childhood. Thereafter, he had suffered from paresis involving the left lower limb, with no relapse or progression of the disease. He began noticing slowly progressive muscle weakness and atrophy in the upper and lower extremities in his 60s. At the age of 72, muscle weakness developed rapidly, and he demonstrated dyspnea on exertion and dysphagia. He died after about 14 years from the onset of muscle weakness symptoms. Autopsy findings demonstrated motoneuron loss and glial scars not only in the plaque-like lesions in the anterior horns, which were sequelae of old poliomyelitis, but also throughout the spine. No Bunina bodies, TDP-43, and ubiquitin inclusions were found. Post-polio syndrome is rarely fatal due to rapid progressive dyspnea and dysphagia. Thus, the pathological findings in the patient are considered to be related to the development of muscle weakness. PMID:26616485

  8. Clinical and Autopsy Diagnoses of Visceral Affections of Patients Who Died Because of Complicated Burns with Multi-organ Failure.

    Taran, A; Baciu, N; Rafulea, V; German, A

    2005-12-31

    The anatomicopathological investigations carried out in a total number of 186 cadavers during the last decade were reviewed. In these retrospective studies of necropsy protocols related to different affections of visceral organ systems that evolved asymptomatically, 30.1% involved the neurological system, 36.0% the uropoiesis system, 34.4% the gastrointestinal system, 52.0% the hepatobiliary system, and 39.7% the cardiovascular system, with a prevalence in the pulmonary system of 64.2%. A comparative analysis of the incidence of affections detected in various visceral organs (on the basis of necropsy data in the 186 burn patients) and the incidence of their clinical manifestations showed that in 35% of patients with extensive and deep burns all of these conditions developed asymptomatically and were diagnosed only through autopsy. PMID:21991003

    2013-07-01

    We report the autopsy case of a 74-year-old woman. Onset of gait disturbance and left-side dominant bilateral motor disturbance in the patient led to bilateral progressive apraxia. This was associated with a decline in motor imagery, right-side dominant atrophy of the central sulcus region, and a decrease in cerebral blood flow during illness. She died of respiratory failure that had progressively worsened over a 9-year period. Pathologically, she exhibited right-side dominant cerebral atrophy; neuronal loss, gliosis, and astrocytic plaques were mainly present in the frontal lobe. She was subsequently diagnosed with corticobasal degeneration (CBD). The premotor and primary motor areas revealed marked degeneration; in addition, severe myelin pallor was observed in these regions, and it was suggested that such pathological features were responsible for the apraxia. We believe the present case is valuable since very few reports have provided a detailed description of clinicopathological apraxia in association with CBD. PMID:23832991

  10. An autopsy case of acute multiple sclerosis with multifocal low density areas in the cerebral white matter on CT scans

    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.)

  11. An autopsy case of multiple myeloma with veno-occlusive disease of the liver induced by ionizing radiation

    An autopsy case of multiple myeloma which accompanied radiation-induced veno-occlusion of the liver is presented. A 62-year-old woman with a chief complaint of low back pain was diagnosed as having multiple myeloma. Approximately one year later, the patient was treated with chemotherapy, consisting of VCR, MCNU, ADR, PSL, and CPA, and X-irradiation of 30 Gy to the bilateral trunk for medically intractable rib pain. The irradiation field included the entire liver. Six months later, she was admitted to the hospital due to abdominal distention and massive amounts of ascites. Various examinations failed to make a qualitative diagnosis. Postmortem examination revealed fibrotic occlusion of the central vein which is typical for veno-occlusion disease of the liver. This finding was restricted to the area that was not shielded, irrespective of anatomical structure, strongly suggesting radiation-induced veno-occlusion of the liver. (N.K.)

  12. A method for quantifying adrenocortical nodular hyperplasia at autopsy: some use of the method in illuminating hypertension and atherosclerosis.

    Tracy, Richard E; White, Steven

    2002-02-01

    Quantifying the severity of adrenocortical nodular hyperplasia at autopsy or surgery has much potential practical value. For instance, this inquiry explores the correlation of adrenal nodularity with features of atherosclerosis in coronary arteries and microvascular features of hypertension in the renal cortex. Tissue retrieved from forensic autopsies in 96 men and women ages 16 to 88 years were evaluated for adrenal nodularity, coronary atheroma, and hypertensive renal microvasculopathies. Formalin-fixed adrenal glands were cut into 0.5-cm thick slices and fixed to plastic sheets with SuperGlue (Ross Products, Inc, Columbus, OH). After ranking the specimens on increasing nodularity, they were judged to fall into 10 distinguishable grades of increasing severity; photographs of a representative in each grade were arranged onto a panel. Each gland was then assigned the grade of the photograph it most resembled. Coronaries and kidneys were evaluated in paraffin sections. Weight and nodularity of adrenal glands increased with age. Men with at least one instance of atheroma in the coronary sample had heavier and more nodular glands (age-adjusted) than in men without atheroma. The differences held stronger statistical significance for nodularity than for weight because nodularity continued to show significance even within age groups sometimes represented by few cases. Hypertensive renal microvasculopathies failed to correlate with any of the adrenal features. Women were too few for the analysis. Findings made with the panel of photographs now available for grading adrenocortical nodular hyperplasia showed interesting correlations with coronary atherosclerosis in this data set, suggesting that use of this method might offer some insight into cardiovascular disease.

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

    Flaxman Abraham D

    2011-08-01

    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 as opposed to expert probabilities (up to 8%. Conclusions Given the widespread use of verbal autopsy for understanding the burden of disease and for setting health intervention priorities in areas that lack reliable vital registrations systems, accurate analysis of verbal autopsies is essential. While InterVA is an affordable and available mechanism for assigning causes of death using verbal autopsies, users should be aware of its suboptimal performance relative to other methods.

  14. Postmortem interval alters the water relaxation and diffusion properties of rat nervous tissue – Implications for MRI studies of human autopsy samples

    Shepherd, Timothy M.; Flint, Jeremy; Thelwall, Peter E; Stanisz, Greg J.; Mareci, Thomas H; Yachnis, Anthony T.; Blackband, Stephen J.

    2008-01-01

    High-resolution imaging of human autopsy tissues may improve our understanding of in vivo MRI findings, but interpretation is complicated because samples are obtained by immersion fixation following a postmortem interval (PMI). This study tested the hypotheses that immersion fixation and PMI's from 0 - 24 hours would alter the water relaxation and diffusion properties in rat cortical slice and spinal cord models of human nervous tissue. Diffusion data collected from rat cortical slices at mul...

    Abstract Background The purpose of this study was to gain knowledge about the circumstances related to suicide among children and adolescents 15 years and younger. Methods We conducted a psychological autopsy, collecting information from parents, hospital records and police reports on persons below the age of 16 who had committed suicide in Norway during a 12-year period (1993-2004) (n = 41). Those who committed suicide were compared with children and adolescents who were killed in accidents ...

  17. The 2002 results of the first series of follow-up studies on Japanese Thorotrast patients and their relationships to autopsy series

    In 1963, a follow-up study was started on 262 war-wounded Japanese ex-servicemen who had been injected with thorotrast into blood vessels between 1931 and 1945. This first series of our follow-up studies on thorotrast patients covered a total of 71 years from 1931 to the present 2002 survey. It was supplemented in 1979 by another follow-up study called the second or Aichi series performed on other thorotrast-injected war-wounded persons. The 2002 survey of the first series indicated that 5 (1.9%) of 262 thorotrast cases were still alive, while 257 (98.1%) had died. Among 1,630 control war-wounded persons not treated with thorotrast, 348 (21.3%) were still alive and 1,282 (78.7%) had died. In an age-matched control population of 3,999,000 persons, 837,175 (20.9%) were alive and 3,161,825 (79.1%) had died. The life span of thorotrast patients was; thus, markedly shorten (about 18 years, P2 test showed that the incidence of these disorders was significantly higher in the thorotrast group than the control group. From 1945 to 2002, autopsies have been performed on 404 thorotrast-treated-patients - 392 injected with thorotrast by vascular route and 12 injected by other routes. In vascularly injected autopsy cases, 266 liver malignancies (67.9%), 28 liver cirrhoses (7.1%), 12 cancers of extrahepatic bile duct (3.1%), 30 hematopoietic malignancies (7.7%); 2 bone sarcomas (0.5%), 16 lung cancers (4.1%), one hemangiosarcoma of the spleen (0.3%), 4 malignant peritoneal tumors (1.0%), and 7 sarcomas at the injection site (1.8%) were found. The relative risk estimate of liver malignancies and hematopoietic malignancies was significantly higher in the autopsied thorotrast patients than in the autopsied controls. (orig.)

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

    2012-01-01

    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 microvesse...

    2015-10-15

    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.

    2014-01-01

    BACKGROUND Verbal autopsy (VA) has been proposed to determine the cause of death (COD) distributions in settings where most deaths occur without medical attention or certification. We develop performance criteria for VA-based COD systems and apply these to the Registrar General of India's ongoing, nationally-representative Indian Million Death Study (MDS). METHODS Performance criteria include a low ill-defined proportion of deaths before old age; reproducibility, including consistency of...

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

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

    2016-01-01

    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 t...

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

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

    1978-01-01

    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.

  5. Streptococcus agalactiae infective endocarditis complicated by large vegetations at aortic valve cusps along with intracoronary extension: An autopsy case report.

    Ro, Ayako

    2016-01-01

    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. PMID:26926519

    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.

    Full Text Available The frequency of myocarditis associated with meningococcal disease in children was reported only in two autopsied series (United States and South Africa. Here we report the frequency of associated myocarditis in 31 children who died of meningoccal infection at Hospital Infantil N.S. da Glória in Vitória, Espirito Santo State, Brazil. The diagnosis was confirmed by isolation of Neisseria meningitidis . At least three sections of fragments of both atria and ventricles were studied using the Dallas Criteria for the morphologic diagnosis of myocarditis. The mean age was 47.6 ± 39.8 months and the mean survival time after the onset of symptoms was 46.1 ± 26.5h (12-112h. Myocarditis was present in 13 (41.9% patients, being of minimal severity in 11 cases and of moderate severity in 2 cases. There were no cases with severe diffuse myocarditis. The frequency of myocarditis was not influenced by sex, presence of meningitis, survival time after the onset of symptoms or use of vasoactive drugs. The frequency of myocarditis reported here was intermediate between the values reported in the only two case series published in the literature (57% in the United States and 27% in South Africa. Although our data confirm the high frequency of myocaditis in meningoccal disease, further investigations are necessary to elucidate the contribution of myocarditis to myocardial dysfunction observed in cases of meningococcal infection in children.

    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. PMID:24849871

    A 58-year-old man with von Recklinghausen's disease was admitted for further investigation of right chest pain. Chest X-ray revealed multiple emphysematous bullae in both lungs and a tumor shadow in the right upper lobe. Bronchofiberscopy was performed, but an adequate specimen was not obtained. The tumor was diagnosed as a non-small-cell lung cancer with direct invasion to the adjacent rib. Although chemotherapy and radiotherapy resulted in decrease in tumor size, the tumor subsequently increased in size and the patient died 14 months after the first admission. Autopsy revealed multiple emphysematous bullae, poorly differentiated adenosquamous cell carcinoma of the lung, gastrointestinal stromal tumor of the stomach, and duodenal carcinoid tumor. This case suggests the possibility that von Recklinghausen's disease associated with emphysematous bullae is a risk factor for lung cancer. It has also been suggested that the genetic abnormality responsible for von Recklinghausen's disease increases the risk for various types of malignancy. Although von Recklinghausen's disease is reportedly associated with various malignant tumors, it is quite rare for von Recklinghausen's disease to be associated with triple non-neurogenic tumors. Careful observation is mandatory for patients with von Recklinghausen's disease. PMID:19827584

    2013-01-01

    Full Text Available Background: With the on-going epidemiological transition, information on the pattern of mortality is important for health planning. Verbal autopsy (VA is an established tool to ascertain the cause of death in areas where routine registration systems are incomplete or inaccurate. We estimated cause-specific mortality rates in rural adult population of 28 villages of Ballabgarh in North India using VA. Materials and Methods: During 2002-2007, trained multi-purpose health workers conducted 2294 VA interviews and underlying cause of death was coded by physicians. Proportional mortality (% was calculated by dividing the number of deaths attributed to a specific cause by the total number of deaths for which a VA was carried out. Findings: 61% of deaths occurred among males and 59% occurred among those aged ≥60 years. The leading causes of death were diseases of the respiratory system (18.7% and the circulatory system (18.1%. Infectious causes and injuries and other external causes, each accounted for around 15% of total deaths followed by neoplasms (6.8% and diseases of the digestive system (4%. Among those 45 years of age or more than half of deaths were attributed to non-communicable diseases (NCDs alone. Accidents and injuries were responsible for one-fourth of deaths in 15-30 years age group. Conclusion: NCDs and injuries are emerging as major causes of death in this region thereby posing newer challenges to public health system.

    Based on the external and internal findings of Bhopal gas disaster victims, it was apparent that the gases and particulate matter came out as an aerosol. This was possibly the pyrolysed, reformulated, reconjugated suspension of constituents of the tank E-610 of Union Carbide India Limited, Bhopal, while it was claimed to be methyl isocyanate (MIC) only. It was postulated by the manufacturer of MIC, that the material inhaled by the victims of the Bhopal gas disaster does not cross the lung barrier (UCC press conference on 14th December 1984). It was observed that the more the victims ran, the more aerosol they inhaled and the fatalities were observed in such victims. The tissues, which were preserved in the deep freeze, were randomly selected and analysed by GC coupled with MS (ITD) Finnigan MAT, UK. 14 out of 34 autopsy cases showed MIC trimer peak in extracts of blood. This was one of the constituents of the aerosol and was also located in the tank residue, thereby proving that the trimer had passed the lung barrier. PMID:1795611

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

    2007-07-01

    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.

    We have demonstrated considerable variability in the volumes of different glomeruli in given individuals (individual glomerular volume: IGV) in a stereologic study of kidneys at forensic autopsy performed to investigate sudden or unexpected death in people without manifest kidney disease. We review some important associations of IGV by subject characteristics and by ethnic groups. IGVs were measured by the Cavalieri method in 30 glomeruli in each of 111 adult males who belonged to 4 ethnic groups, i.e. US Whites, African-Americans, Africans from Senegal, and Australian Aborigines. Correlations of pooled IGV values with certain subject characteristics were evaluated in the US Whites. Pooled IGV data were compared in subjects across the 4 ethnic groups. In US Whites, mean IGV and its variance were greater with higher age, lower nephron number, lower birth weight, and with gross obesity, hypertension and cardiovascular death. In comparisons by ethnic group, mean IGV and IGV ranges were higher in African-Americans and Australian Aborigines than in US Whites and African Senegalese subjects. We conclude that glomerular enlargement with volume heterogeneity marks more advanced age, relative nephron deficiency, lower birth weight, obesity, hypertension, and advanced cardiovascular disease. The findings in African-Americans and Australian Aborigines suggest that larger IGVs and volume heterogeneity might mark populations with accentuated susceptibility to hypertension and kidney disease, but the data need to be further examined in the context of the determining characteristics defined in the US Whites.

  15. Autopsy findings of human fetuses of descendant (F1, F2) of the A-bomb survivors

    An analysis was made of autopsy population of human fetuses and neonates (652 cases for F1 and 115 cases for F2 ) obtained from A-bomb exposed and non-exposed groups. In a study of delivery mode, the incidence of abnormal findings, including congenital anomaly, was found higher in the group of spontaneous delivery than the group of artificial delivery. Anomaly of the heart or great vessels was the most common, followed by anomaly of the central nervous system and urinary system in both F1 and F2 groups. Abnormal findings in the group of spontaneous delivery were observed in a total of 148 cases. For evaluable 32 cases in which the exposure distance was confirmed, these abnormalities were not related to distance from the hypocenter. Anomaly in this group was seen in 74 cases, in which autosomal dominant inheritance had induced chondrodystrophy (two cases) and polycystic kidney disease (one). For F2, anomaly was observed in 22 cases in the group of spontaneous delivery. Polycystic kidney disease was seen in each one case exposed at ≤2,000 m or 2,000-4,000 m from the hypocenter. The incidence of other anomalies was independent of exposure distance or either paternal or maternal exposure to A-bombing. Nor was correlation between the incidence of macerated fetuses and exposure distance or either paternal or maternal exposure. (N.K.)

    Herbal remedies have been used since ancient times and it is now known that they are not completely free of adverse effects. We present the case of a 41-year-old Chinese man, who died in renal failure because he consumed a herbal preparation called "Fen Qing Wu Lin Wan", having GuanMu Tong as main ingredient, for about 1 month. GuanMu Tong is derived from the plant Aristolochia manshuriensis which contains aristolochic acid. Aristolochic acid is being reported as the causative agent of what is now called aristolochic acid nephropathy (AAN) which includes Chinese herb nephropathy (CHN) and Balkan endemic nephropathy (BEN), all having renal impairment as hallmark for the disease. The gross autopsy showed multiple punctate hemorrhages over the limbs, pleural effusion, and edematous lungs with consolidation, mild myocardial hypertrophy and normal-looking kidneys. Microscopic renal tissue examination showed severe degeneration, necrosis and desquamation of renal tubular epithelial cells, presence of protein cast and a widened, edematous interstitium with interstitial fibrosis. We also provide the clinical presentation of the deceased as reported in the medical records and briefly review the literature pertinent to similar cases. PMID:20193994

    A 69-year-old woman developed subacute cerebellar ataxia and tremors in all four limbs in April 1996. Laboratory examination showed elevated antibodies against Ro and La. Head magnetic resonance imaging showed T(2) high-intensity lesions in the cerebellar white matter bilaterally and later in the pons. In April 2000, she died of multiple organ failure with incidental colon cancer. The autopsy showed atrophic parotid glands with an accumulation of lymphocytes around the ducts, confirming the diagnosis of Sjogren's syndrome histopathologically. The neuropathological examination revealed severe necrotic lesions in the cerebellar white matter bilaterally with several foci of perivenous demyelination in the periphery of the lesions and similar demyelinated areas in the pons. Immunohistochemistry with anti-JC virus antibody demonstrated no positive inclusions. A single focus of granulomatous arteritis was observed in one subarachnoid artery. The combination of Sjogren's syndrome, granulomatous angitis, and foci of perivenous demyelination suggests that an autoimmune mechanism played an important role in causing the necrotic lesions in the cerebellar white matter in this case.

    Archival formalin-fixed paraffin-embedded (FFPE) human tissue collections are typically in poor states of storage across the developing world. With advances in biomolecular techniques, these extraordinary and virtually untapped resources have become an essential part of retrospective epidemiological studies. To successfully use such tissues in genomic studies, scientists require high nucleic acid yields and purity. In spite of the increasing number of FFPE tissue kits available, few studies have analyzed their applicability in recovering high-quality nucleic acids from archived human autopsy samples. Here we provide a study involving 10 major extraction methods used to isolate total nucleic acid from FFPE tissues ranging in age from 3 to 13years. Although all 10 methods recovered quantifiable amounts of DNA, only 6 recovered quantifiable RNA, varying considerably and generally yielding lower DNA concentrations. Overall, we show quantitatively that TrimGen's WaxFree method and our in-house phenol-chloroform extraction method recovered the highest yields of amplifiable DNA, with considerable polymerase chain reaction (PCR) inhibition, whereas Ambion's RecoverAll method recovered the most amplifiable RNA.

    Gliomatosis cerebri is a rare diffuse glioma that is neither mass-forming nor necrotic, and does not disrupt existing structures. Gliomatosis occurring in the cerebellum is known as gliomatosis cerebelli, and only three such cases examined by biopsy have been reported. Here we describe the first autopsy findings of a patient who was diagnosed as having gliomatosis in the cerebellum. Neuropathological examination identified the tumor cells as being positive for glial fibrillary acidic protein, vimentin and nestin, with atypical nuclei that were cashew-nut- or dishcloth-gourd-shaped. These tumor cells were dense in the right cerebellum, but also spread broadly throughout the brain including the left cerebrum and optic nerve. Mitotic figures were frequently seen in the cerebellum, brain stem and cerebrum. Scherer's secondary structures were evident not only in the cerebellum but also the cerebrum. No necrosis, microvascular proliferation or destruction of anatomical structures was detected in the whole brain. Differences in the origin of the tumors of the gliomatoses cerbri and cerebelli suggests these tumors are different types of brain tumors. Thus the findings support that the gliomatosis cerebelli is a novel type of brain tumor classification. Furthermore, by the similarities of the histological features among the tumors, it appears appropriate to establish a novel category of "gliomatosis encephali" which includes both gliomatosis cerebri and gliomatosis cerebelli.

    2010-01-01

    We report an autopsy case of segmental arterial mediolysis (SAM) of various phases occurring in both the intracranial vertebral artery (IVA) and intra-abdominal arteries. The patient was a 70-year-old male found dead in his house. The cause of death was massive intra-abdominal hemorrhage owing to a ruptured right gastroepiploic artery. Histopathological examination revealed that there was a broad arterial dissection as long as 20 cm in the right gastroepiploic artery associated with SAM in the injurious phase. In addition, SAM in the reparative phase was observed as organized arterial dissections in the left gastric artery. Furthermore, SAM in the reparative phase was detected as an arterial dissection in the right IVA undergoing an organizing process. These three lesions were considered to have developed at different times. SAM occurring in both the intra-abdominal and intracranial vertebral arteries is extremely rare. This coincidence may provide a clue to the relationship between SAM and spontaneous IVA dissection. PMID:19375356

  2. Ovarian small cell carcinoma of pulmonary type appearing in ante-mortem ascites: An autopsy case and review of the literature

    Hirotsugu Hashimoto, MD

    2015-09-01

    Full Text Available Ovarian small cell carcinoma of pulmonary type (OSCCPT is an extremely rare and aggressive disease. The diagnostic significance of cytology of ascites for OSCCPT, however, has not been shown so far. Here, we report the diagnosis of this carcinoma in an autopsy case with ante-mortem cytology of ascites. A 75 year-old woman was detected with bilateral ovarian cancer by radiological imaging. Although operation was planned, massive ascites was discovered a few weeks later. Ascites was removed with abdominocentesis, which cytologically diagnosed presence of carcinoma, suspicious of adenocarcinoma. A few days later, she died. From autopsy samples, we diagnosed this case as bilateral OSCCPT, showing neuroendocrine differentiation by immunohistochemistry. We reviewed ante-mortem cytology of ascites and found scattered small atypical cells. Immunocytochemical study of the cell block of the ascites showed neuroendocrine differentiation of the atypical cells in an identical manner as the autopsy specimens. Since small atypical cells of OSCCPT often exist with other histological tumor components, careful screening of all cells on the preparation is advisable to accurately diagnose OSCCPT by cytology of ascites.

    2014-01-01

    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.

  4. 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

    Peter Byass

    2015-06-01

    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 between InterVA–4 and physician–coded findings over this large and diverse data set. Although these analyses cannot prove that either approach constitutes absolute truth, there was high public health equivalence between the findings. Given the urgent need for adequate cause of death data from settings where deaths currently pass unregistered, and since the WHO 2012 verbal autopsy standard and InterVA–4 tools represent relatively simple, cheap and available methods for determining cause of death on a large scale, they should be used as current tools of choice to fill gaps in cause of death data.

    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.

    Full Text Available El objetivo principal del presente trabajo fue identificar las discrepancias clínico-patológicas en las autopsias realizadas en la institución. Se revisaron 53 autopsias de casos clínicos en adultos en el período comprendido entre enero de 2005 y junio de 2009, realizadas en el servicio de Anatomía Patológica del Hospital Privado de Córdoba, Argentina. Se excluyeron seis debido a información insuficiente. Se aplicó la clasificación de Goldman y col. para establecer las discrepancias clínico-patológicas entre los diagnósticos pre y post-mortem. Los diagnósticos clínicos más frecuentes fueron las infecciones respiratorias y el tromboembolismo pulmonar agudo. Los hallazgos de autopsia más frecuentes fueron las infecciones respiratorias y el infarto agudo de miocardio. Se detectaron 17 discrepancias mayores y 30 concordancias, no se detectaron discrepancias menores. Las infecciones respiratorias fueron la principal causa de error, seguidas por el infarto agudo de miocardio. Concluimos que en 17/47 (37% de los casos se realizó un diagnóstico clínico diferente al post-mortem, y que las infecciones respiratorias constituyen el principal tipo de error. Se sugiere adoptar estrategias informativas y educativas, revalorizar la autopsia y las prácticas clínicas tradicionales.The main objective of this study was to identify the clinical-pathological discrepancies in autopsies performed in the institution.

Six autopsies were excluded due to insufficient information. The Goldman et al. classification was applied to establish clinico-pathologic discrepancies between clinical diagnoses and autopsy findings. Frequently clinical diagnoses were respiratory infections and acute pulmonary embolism. The most frequently reported postmortem diagnoses were respiratory infections and acute myocardial infarction. There were 17 major discrepancies and 30 coincidences. No any minor discrepancy was detected. Respiratory infections were the main cause of error, followed by myocardial infarction. We conclude that in 17/47 (37% of cases the pre-mortem and postmortem diagnoses were different, and that respiratory infections were the main cause of error. We suggest to adopt educational and informative strategies, to revalue the importance of autopsy, and traditional clinical practices.

    An autopsied case of complicated form of spastic paraplegia with many unusual clinical and pathological features is reported. Present case: a 31-year-old male. His parents are first cousins. Pregnancy and delivery had been unremarkable. Though he was mentally retarded, his physical development was normal. He was considered normal until age 10. He suffered from progressive disturbance in gait at the age of 11. He could not walk without assistance at the age of 22. Neurological examination revealed the following findings. He was obese and mentally deteriorated. Spastic paraplegia with increased tendon reflexes and pathological reflexes was prominent. Though slight sensory disturbance was present in the lower extremities, neither involuntary movement nor cerebellar ataxia was observed. In the age of late 20's, dementia, general muscular atrophy, and Parkinsonism developed. At the age of 30, he could not move by himself. He was apathic and indifferent, and showed forced laughing. Muscle tonus was flaccid because of general muscular atrophy and peripheral neuropathy. He died of acute gastric enlargement. Neuropathological findings were characterized by mal-development of the central nervous system (CNS) and the multisystem degeneration. There existed cerebral white matter hypoplasia with hypogenesis of the corpus callosum and ectopia of neurons of the cerebral and cerebellar cortex. Hypoplasia of melanin pigment was also observed in the remaining neurons of the substantia nigra and the locus ceruleus. Many neurons in the CNS included lipofuscin granules of variable shapes. Some of them showed clusters of several block-like inclusions which were green with luxol fast blue and cresyl violet stain.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2076353

  8. Combining diagnostic categories to improve agreement between death certificate and autopsy classifications of cause of death for atomic bomb survivors, 1950-87

    Several investigators have observed less-than-desirable agreement between death certificate diagnoses and autopsy diagnoses for most specific causes of death, and even for some causes grouped by major disease category. Our results from data on 5130 autopsies of members of the Life Span Study cohort of atomic bomb survivors in Hiroshima and Nagasaki conducted prior to September 1987 were equally discouraging. Among diseases with more than 10 cases observed, confirmation rates ranged from 13 % to 97 % and detection rates from 6 % to 90 %. Both rates were greater than 70 % for only 6 of 60 disease categories studied and for only 1 of 16 categories defined by major International Classification of Disease categories (neoplasms). This deficiency suggests cautious interpretation of results from studies based on death certificate diagnoses. To determine whether any groupings of diagnoses might meet acceptable accuracy requirements, we applied a hierarchical clustering method to data from these 5130 cohort members. The resulting classification system had 10 categories: breast cancer; other female cancers; cancers of the digestive organs; cancer of the larynx; leukemia; nasal, ear, or sinus cancer; tongue cancer; external causes; vascular disease; and all other causes. Confirmation and detection rates for each of these categories were at least 66 %. Although the categories are broad, particularly for nonneoplastic diseases, further divisions led to unacceptable accuracy rates for some of the resulting diagnostic groups. Using the derived classification system, there was 72 % agreement overall between death certificate and autopsy diagnoses compared to 53 % agreement for a second system obtained by grouping strictly by major disease category. Eighty-seven percent agreement was observed for a similar classification system with vascular disease grouped with all other nonneoplastic diseases. Further agglomeration achieved very little additional improvement. (J.P.N.)

  9. Effect of metallothionein core promoter region polymorphism on cadmium, zinc and copper levels in autopsy kidney tissues from a Turkish population

    Metallothioneins (MTs) are metal-binding, low molecular weight proteins and are involved in pathophysiological processes like metabolism of essential metals, metal ion homeostasis and detoxification of heavy metals. Metallothionein expression is induced by various heavy metals especially cadmium, mercury and zinc; MTs suppress toxicity of heavy metals by binding themselves to these metals. The aim of this study was to investigate the association between the - 5 A/G metallothionein 2A (MT2A) single nucleotide polymorphism (SNP) and Cd, Zn and Cu levels in the renal cortex from autopsy cases. MT2A core promoter region - 5 A/G SNP was analyzed by PCR-RFLP method using 114 autopsy kidney tissues and the genotype frequencies of this polymorphism were found as 87.7% homozygote typical (AA), 11.4% heterozygote (AG) and 0.9% homozygote atypical (GG). In order to assess the Cd, Zn and Cu levels in the same autopsy kidney tissues, a dual atomic absorption spectrophotometer system was used and the average levels of Cd, Zn and Cu were measured as 95.54 ± 65.58 ?g/g, 181.20 ± 87.72 ?g/g and 17.14 ± 16.28 ?g/g, respectively. As a result, no statistical association was found between the - 5 A/G SNP in the MT2A gene and the Zn and Cu levels in the renal cortex (p > 0.05), but considerably high accumulation of Cd was monitored for individuals having AG (151.24 ± 60.21 ?g/g) and GG genotypes (153.09 ?g/g) compared with individuals having AA genotype (87.72 ± 62.98 ?g/g) (p < 0.05). These results show that the core promoter region polymorphism of metallothionein 2A increases the accumulation of Cd in human renal cortex.

Conclusiones. La alta cifra de errores diagnósticos y la consecuente baja concordancia clínicopatológica apoyan el hecho de que, a pesar del avance tecnológico en los procedimientos diagnósticos, es necesario realizar necropsias con el fin de documentar de manera más definitiva el control de calidad del ejercicio de la medicina.Objective. To determine the degree of concordance between clinical and autopsy diagnosis. Material and methods. The records of 67 autopsies and clinical files of children and adults, comprising the years 1995 to 1996, from a third level hospital in the State of Veracruz, Mexico, were revised. The concordance score was calculated with the statistical kappa. Results. In general, the rate of autopsy was 10.5%, with higher frequency for children (17.5%. In children, 59% of clinical diagnoses revealed mistakes and in adults, 57%. The degree of agreement in the underlying cause ante and postmortem was 6% in children and 41% in adults. Conclusions The high rate of diagnostic error and low concordance score between clinical and autopsy diagnosis strongly suggests that, in spite of increased availability of modern diagnostic techniques, the necessity of postmortem studies to control the level of medical practice is evident.

  13. Association of the apolipoprotein E {epsilon}4 allele with clinical subtypes of autopsy-confirmed Alzheimer`s Disease

    Zubenko, G.S.; Stiffler, S.; Kopp, U. [Univ. of Pittsburgh School of Medicine, PA (United States)] [and others

    1994-09-15

    Consistent with previous reports, we observed a significant association of the APOE {epsilon}4 allele with Alzheimer`s Disease (AD) in a series of 91 autopsy-confirmed cases. The {epsilon}4 allele frequency was higher in cases with a family history of AD-like dementia (0.54 {+-} 0.07), although the {epsilon}4 allele frequency in the AD cases with a negative family history (0.38 {+-} 0.05) remained significantly greater than that for the non-AD control group (0.13 {+-} 0.03). A similar increase in {epsilon}4 allele frequency (0.54 {+-} 0.07) was observed in the AD cases with amyloid angiopathy, compared to those who did not have amyloid angiopathy (0.35 {+-} 0.04). Contrary to previous reports, no effect of the dosage of the {epsilon}4 allele was found on the age of onset of dementia among the AD cases and, contrary to reports suggesting an association of {epsilon}4 and atherosclerosis, the {epsilon}4 allele frequency was similar in cases with or without concurrent brain infarcts. Modest but consistent correlations were observed between the dosage of {epsilon}4 alleles and the cortical density of senile plaques, but not neurofibrillary tangles. The last finding suggests that the pathogenic events mediated by the {epsilon}4 allele may be more directly involved in the formation of senile plaques, the identifying lesions in AD, than neurofibrillary tangles. A robust association of both the presence of an {epsilon}4 allele and a family history of AD-like dementia with concurrent amyloid angiopathy occurred within our sample of AD cases. This association arose from an interaction of the {epsilon}4 allele with a separate familial factor for which a family history of dementia served as a surrogate. These results suggest that amyloid angiopathy may be a common or central feature of a form of familial AD that is associated with the transmission of the APOE {epsilon}4 allele. 22 refs., 2 figs., 5 tabs.

  14. Using verbal autopsy to track epidemic dynamics: the case of HIV-related mortality in South Africa

    Mee Paul

    2011-08-01

    Full Text Available Abstract Background Verbal autopsy (VA has often been used for point estimates of cause-specific mortality, but seldom to characterize long-term changes in epidemic patterns. Monitoring emerging causes of death involves practitioners' developing perceptions of diseases and demands consistent methods and practices. Here we retrospectively analyze HIV-related mortality in South Africa, using physician and modeled interpretation. Methods Between 1992 and 2005, 94% of 6,153 deaths which occurred in the Agincourt subdistrict had VAs completed, and coded by two physicians and the InterVA model. The physician causes of death were consolidated into a single consensus underlying cause per case, with an additional physician arbitrating where different diagnoses persisted. HIV-related mortality rates and proportions of deaths coded as HIV-related by individual physicians, physician consensus, and the InterVA model were compared over time. Results Approximately 20% of deaths were HIV-related, ranging from early low levels to tenfold-higher later population rates (2.5 per 1,000 person-years. Rates were higher among children under 5 years and adults 20 to 64 years. Adult mortality shifted to older ages as the epidemic progressed, with a noticeable number of HIV-related deaths in the over-65 year age group latterly. Early InterVA results suggested slightly higher initial HIV-related mortality than physician consensus found. Overall, physician consensus and InterVA results characterized the epidemic very similarly. Individual physicians showed marked interobserver variation, with consensus findings generally reflecting slightly lower proportions of HIV-related deaths. Aggregated findings for first versus second physician did not differ appreciably. Conclusions VA effectively detected a very significant epidemic of HIV-related mortality. Using either physicians or InterVA gave closely comparable findings regarding the epidemic. The consistency between two physician coders per case (from a pool of 14 suggests that double coding may be unnecessary, although the consensus rate of HIV-related mortality was approximately 8% lower than by individual physicians. Consistency within and between individual physicians, individual perceptions of epidemic dynamics, and the inherent consistency of models are important considerations here. The ability of the InterVA model to track a more than tenfold increase in HIV-related mortality over time suggests that finely tuned "local" versions of models for VA interpretation are not necessary.

  15. Local perceptions of causes of death in rural South Africa: a comparison of perceived and verbal autopsy causes of death

    Laith Hussain-Alkhateeb

    2015-07-01

    Full Text Available 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 understanding of causes of death may be detrimental to public health. These findings also illustrate the importance of using rigorous and standardised VA methods rather than relying on informants’ reported causes of death.

  16. A report of two cases: post flood autopsy findings in urban patients with an unusual presentation of leptospirosis with hemorrhagic pneumonia in government medical college, Surat

    2011-01-01

    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.

    2013-03-01

    Fatal acute methamphetamine (MA) poisoning in cases of internal drug trafficking is rarely described in the literature. This case study reports an MA 'body packer' who died from fatal methamphetamine intoxication due to leaking drug packages in the alimentary tract. The deceased was examined by postmortem computed tomography (PMCT), and the results were correlated to subsequent autopsy and toxicological findings. The deceased was arrested by the police when he was found disoriented in the city of Kuala Lumpur. He was transferred to the emergency department on suspicion of drug abuse. The initial drug screening was reactive for amphetamines. Shortly after admission to the hospital, he died despite rigorous resuscitation attempts. The postmortem plain chest and abdominal radiographs revealed multiple suspicious opacities in the gastrointestinal tract attributable to body packages. An unenhanced whole body PMCT revealed twenty-five drug packages, twenty-four in the stomach and one in the transverse colon. At least two were disintegrating, and therefore leaking. The autopsy findings were consistent with the PMCT results. Toxicology confirmed the diagnosis of fatal methamphetamine intoxication. PMID:23404531

  18. The association between obesity and lethal blood alcohol concentrations: a nationwide register-based study of medicolegal autopsy cases in Sweden.

    Wingren, Carl Johan; Ottosson, Anders

    2014-11-01

    Obesity is a global problem and in aspects of lethal ethanol intoxications virtually unexplored. The cause of death in ethanol intoxication is generally considered to be suppression of the respiratory function. Previous research indicates that respiratory function is more vulnerable in obese subjects than in those of normal weight. We hypothesized that lethal blood alcohol concentration (BAC) is lower in obese subjects compared to those of normal weight. We used the Swedish medicolegal autopsy register and identified all medicolegal autopsy cases in Sweden during the period from 1999 to 2013 (N=79,060), and identified 1545 cases with ethanol intoxication identified as the primary cause of death. We studied the association between body mass index and lethal BAC using logistic regression models that we adjusted using several potential confounders such as age, sex, drugs, and extent of decomposition. We observed an association between obesity and lower lethal BACs. The estimated adjusted odds ratio of the association between obesity and a lethal BAC >3‰, using subjects of normal weight as reference, was 0.54, 95% confidence interval: 0.39-0.74. The result indicates that in obese subjects the lethal BAC is lower than in those of normal weight. PMID:25300068

    We report the clinical and autopsy features of a 65-year-old Japanese man who clinically exhibited overlap of both neuro-Behçet's disease (NBD) and amyotrophic lateral sclerosis (ALS). The patient had a HLA-B51 serotype, a recent history of uveitis and had suffered paraparesis, sensory and autonomic disturbance, frontal signs and tremor. A brain and spine MRI study revealed a longitudinally extensive thoracic cord (Th) lesion, but no apparent intracranial abnormalities. The lesion extended ventrally from Th4 to Th9, exhibiting low intensity on T1-weighted images, high intensity on T2-weighted and fluid-attenuated inversion recovery images and gadolinium enhancement. The patient's upper and lower motor neuron signs and sensory disturbance worsened and he died 16 months after admission. At autopsy, the spinal cord and brain exhibited characteristic histopathological features of both NBD and ALS, including chronic destruction of the ventral thoracic white and gray matter, perivascular lymphocytic infiltration, binucleated neurons, lower and upper motor neuron degeneration, Bunina bodies and skein-like inclusions. Although incidental coexistence of these rare disorders could occur in an individual, this case raises the possibility of a pathomechanistic association between NBD and ALS. PMID:24118427

    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. PMID:26969767

    2015-06-01

    Full Text Available Background This study was one of a set of verbal autopsy investigations undertaken by the WHO/UNCEF–supported Child Health Epidemiology Reference Group (CHERG to derive direct estimates of the causes of neonatal and child deaths in high priority countries of sub–Saharan Africa. The objective of the study was to determine the cause distributions of neonatal (0–27 days and child (1–59 months mortality in Niger. Methods Verbal autopsy interviews were conducted of random samples of 453 neonatal deaths and 620 child deaths from 2007 to 2010 identified by the 2011 Niger National Mortality Survey. The cause of each death was assigned using two methods: computerized expert algorithms arranged in a hierarchy and physician completion of a death certificate for each child. The findings of the two methods were compared to each other, and plausibility checks were conducted to assess which is the preferred method. Comparison of some direct measures from this study with CHERG modeled cause of death estimates are discussed. Findings The cause distributions of neonatal deaths as determined by expert algorithms and the physician were similar, with the same top three causes by both methods and all but two other causes within one rank of each other. Although child causes of death differed more, the reasons often could be discerned by analyzing algorithmic criteria alongside the physician's application of required minimal diagnostic criteria. Including all algorithmic (primary and co–morbid and physician (direct, underlying and contributing diagnoses in the comparison minimized the differences, with kappa coefficients greater than 0.40 for five of 11 neonatal diagnoses and nine of 13 child diagnoses. By algorithmic diagnosis, early onset neonatal infection was significantly associated (?2?=?13.2, P?autopsy conducted in the context of a national mortality survey can provide useful estimates of the cause distributions of neonatal and child deaths. While the current study found reasonable agreement between the expert algorithm and physician analyses, it also demonstrated greater plausibility for two algorithmic diagnoses and validation work is needed to ascertain the findings. Direct, large–scale measurement of causes of death complement, can strengthen, and in some settings may be preferred over modeled estimates.

  3. Significance of fibrotic bands in utero--Amniotic band sequence with limb body wall complex: A rare case of fetal autopsy.

    Devi, P Lekshmi; Cicy, P J; Thambi, Renu; Poothiode, Usha

    2015-01-01

    Amniotic band sequence (ABS) includes a wide spectrum of abnormalities resulting from entrapment of various fetal parts from a disrupted amnion, ranging from a mere constriction ring affecting a finger to a fatal form called limb body wall complex (LBWC). Reported cases of ABS with LBWC are very few. The spectrum of anomalies depends on which part gets entrapped and at what point of gestation. Hence, the clinical presentation can be extremely variable. Early detection of such cases using sonology is really challenging due to the small size of the fibrotic bands. Here, we present a case of amniotic band syndrome with LBWC in a fetus at 24 weeks of gestation, which was referred for an autopsy. The fetus also showed scoliosis, gastroschisis, lumbosacral meningocele, congenital talipes equinovarus, and cleft palate, thus having features of placenta cranial and placenta abdominal phenotype which is very rare.

  4. Levels of some trace elements in selected autopsy organs, and in hair and blood samples from adult subjects of the Italian population

    This study, which is part of a research program for the determination of trace element reference levels in various human tissues for the Italian population, presents the concentrations of Se, Hg, Cr, Cs, Sc, Rb, Zn, Fe, Co, and Sb in lung, liver, spleen, and kidney autopsy samples taken from 14 adult subjects of the Italian population who died from accidental causes. Concentrations of the same trace elements are given also for blood and hair samples taken from subjects of the general Italian population and of a population group living in a small coastal town that has an average annual fish consumption well above the national average. The analytical method used was Instrumental Neutron Activation Analysis. The levels and distribution of the trace elements in the various human organs examined are analyzed and discussed

  5. Lung cancer at autopsy in A-bomb survivors and controls, Hiroshima and Nagasaki, 1961--1970. II. Smoking, occupation and A-bomb exposure

    The apparent effect of ionizing radiation on lung cancer in A-bomb survivors has not been large enough to still doubts as to its validity. It has seemed essential to determine whether the apparent radiation effect could have resulted from a confounding of heavy smoking and high radiation dose, or if the occupational exposure of high-dose subjects with lung cancer was suggestive of the influence of environmental hazards other than radiation. The available series consists of 204 subjects with lung cancer verified by autopsy, 61 of whom were low-dose (less than 1 rad) and 13 high-dose (200+ rads) subjects. No evidence could be found that the influence of either smoking or occupational exposure upon lung cancer was exerted so as to suggest that the apparent radiation effect is other than real. The study also provides additional evidence of the relationship between lung cancer and smoking in Japan

    2012-01-01

    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. PMID:23035163

  7. Mercury accumulations in brains from populations exposed to high and low dietary levels of methyl mercury. Concentration, chemical form and distribution of mercury in brain samples from autopsies

    Pedersen, M B; Hansen, J C; Mulvad, G; Pedersen, Henning Sloth; Gregersen, M; Danscher, Gorm

    1999-01-01

    Autopsy samples from 17 Greenlanders and 12 Danes were analysed for total and organic mercury by atomic absorption spectrophotometry, and for cellular localisation by autometallography. The concentration of total mercury in the Greenlanders (median: 174 micrograms Hg/kg wet weight brain tissue......, range 59-4782, highest in cerebellum: 492) was found to be significantly higher than in the Danish group (3.7 micrograms Hg/kg w.w., range 1.2-11.8). Furthermore, the total concentration of mercury was positively correlated to age (rho = 0.56, p <0.05), and the fraction of methyl mercury was negatively...... correlated to age (rho = -0.66, p <0.01) among the Greenlanders. This suggests an age dependent accumulation of total mercury and a slow transformation of methyl mercury to inorganic mercury in the brain.

    A 50-year-old man who underwent hemodialysis (HD) at local outpatient HD center due to end-stage renal disease (ESRD) was transferred to our hospital because of pneumonia. He had severe emaciation and past history of congestive heart failure. Presenting symptoms almost consistently involved difficulty in hearing and recurrent attacks of migraine-like headaches. He was diagnosed with dilated cardiomyopathy, showing diastolic mechanical dyssynchrony by tissue Doppler echocardiography. On the day of death, he had hematemesis and hemorrhagic shock. Autopsy revealed perforation of duodenum, and genetic analysis using mitochondrial DNA from cardiac muscle and iliopsoas muscle revealed a 3243A > G mutation in the mitochondrial tRNA(Leu(UUR)) gene, which is related to mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS). Multiple organ failure due to the mutation of mitochondrial DNA with gastrointestinal bleeding is not a common. PMID:21631236

  9. 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

    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.)

  10. [Civil and criminal laws regarding the donation, removal and transfer of organs (Transplantation Law) in Germany with respect to administrative and clinical autopsies].

    Dufková, J

    2000-07-01

    In the Federal Republic of Germany, transplantation medicine, which is relatively young and still developing, is now regulated by the law governing the donation, removal and transfer of organs (Transplantation Law--TPG) of 05. 11. 1997 and has been given a legal basis which satisfies even present-day standards. By evaluating the highly personal rights to potential organ donor and of his next-of-kin against the interests of maintaining life and health of others, the law works along the lines of the so-called extended consent solution. The basic civil law stipulations of sections 3 + 4 TPG, while protecting the donor's individual freedom of decision, give his next-of-kin or trusted confidant at or immediately following death the right to communicate his presumes wishes. In addition, it must be stated that through recent decisions handed down by the Federal Constitutional Court (Bundesverfassungsgericht) in response to various complaints, this regulation has been recognised as conforming to constitutional laws. The basic content of the penal regulations states that violations of civil law rules and trafficking in organs are an offence. Current disclosed requirements for suitable donor organs, in particular for 1998, make it appear likely that the current deficit can be eliminated by the introduction of the organisational measures contained in the law. In conclusion, the situation with regard to autopsy should be addressed since, in contrast to the federal transplantation law which applies to all states, autopsy is regulated differently and, from a legal-political standpoint, unsatisfactorily by each individual state. It is desirable that this legal ambiguity be corrected by standardising the inconsistent and at times non-existent legal stipulations. PMID:10974752

    Point-of-care tests for tuberculous meningitis (TBM) are needed. We studied the diagnostic accuracy of the lipoarabinomannan (LAM) lateral flow assay (LFA), LAM enzyme-linked immunosorbent assay (ELISA), and Xpert MTB/RIF in cerebrospinal fluid (CSF) in an autopsy cohort of Ugandan HIV-infected adults. We obtained written informed consent postmortem from the next of kin. A complete autopsy was done and CSF obtained. We performed LAM LFA (on unprepared and supernatant CSF after heating and spinning), LAM ELISA, and Xpert MTB/RIF on the CSF samples. Accuracy parameters were calculated for histopathological TBM and also for the composite standard, including Xpert MTB/RIF-positive cases. We tested CSF of 91 patients. LAM LFA had a sensitivity of 75% for definite histopathological TBM, ELISA a sensitivity of 43%, and Xpert MTB/RIF a sensitivity of 100% and specificities of 87%, 91%, and 87%, respectively. LAM LFA had a sensitivity of 50% for definite and probable histopathological TBM, ELISA a sensitivity of 38%, and Xpert MTB/RIF a sensitivity of 86% and specificities of 70%, 91%, and 87%, respectively. LAM LFA had a sensitivity of 68% for the composite standard and ELISA a sensitivity of 48% and specificities of 78% and 98%, respectively. The rapid diagnostic tests detected TBM in 22% to 78% of patients not on anti-TB treatment. Point-of-care tests have high accuracy in diagnosis of TBM in deceased HIV-infected adults. LAM LFA in CSF is a useful additional diagnostic tool. PMID:26063865

    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.

    Full Text Available El estudio de más de 14 000 autopsias ha permitido integrar un conjunto de alteraciones morfológicas con el término de daño múltiple de órganos. El propósito del presente trabajo fue determinar la vigencia de los elementos diagnósticos iniciales del daño múltiple de órganos en fallecidos con factores causales. Se realizó un estudio de estos y se analizaron las relaciones de las causas de muerte con los factores causales y el número de órganos afectados con la estadía hospitalaria. Se revisaron 448 fallecidos y a quienes se les había realizado autopsia en el Instituto Superior de Medicina Militar "Dr. Luis Díaz Soto". Se revisaron los protocolos de autopsias, historias clínicas y láminas histopatológicas. Se seleccionaron los 145 casos con criterio de daño múltiple de órganos que constituyeron el objeto de estudio del presente trabajo. Los resultados muestran la presencia del daño múltiple de órganos en un tercio de los fallecidos, que fue mayormente en los menores de 50 años y en los procedentes de las terapias y unidades de cuidados intermedios. Se destacan entre las causas de muerte el daño tisular severo y la infección. Los órganos más afectados fueron los pulmones, el intestino, las glándulas suprarrenales, el hígado y el cerebro. Estuvo presente el daño múltiple de órganos en el 59,3 % de los fallecidos entre los primeros 4 días de estadía hospitalaria, con predominio del daño en 5 y 6 órganos. El daño múltiple de órganos se presentó en más de un tercio de los casos estudiados.

The protocols of the autopsy, medical histories and histopathological laminae were reviewed. The 145 cases with criterion of multiple organ damage that were the object of study of this paper, were selected. The results showed the presence of multiple organ damage in a third of the dead. It was mostly observed in those under 50 and in the ones coming from the intermediate therapy and care units. Among the death causes, the severe tissue damage and infection stood out. The most affected organs were the lungs, the bowels, the suprarenal glands, the liver and the brain. Multiple organ damage was present in 59.3 % of the deceased in the first 4 days of hospital stay, with predominance of damage in 5 and 6 organs. The response of the organism to the causal factors triggers the systemic inflammatory response that is morphologically expressed in the multiple organ damage and may cause the death of the patient.

  16. Over-representation of the APOE*4 allele in autopsy confirmed early- and late-onset sporadic Alzheimer`s disease

    Kamboh, M.I.; DeKosky, S.T.; Ferrell, R.E. [Univ. of Pittsburgh, PA (United States)

    1994-09-01

    Apolipoprotein E binds to {beta}-amyloid peptide in senile plaques and neurofibrillary tangles in Alzheimer`s disease (AD). Recent studies have identified the APOE*4 allele as a major predisposing genetic factor for late-onset familial AD as well as in sporadic AD. Most of these association studies are based on clinically diagnosed AD cases with little data available on autopsy confirmed, definite AD. To characterize the distribution of APOE polymorphism in autopsy confirmed sporadic AD cases, we determined APOE genotypes in 111 DNA samples (aged 51-101 years) extracted from brain tissues which were available from the University of Pittsburgh Alzheimer`s Disease Research Center. The APOE data was compared between the AD group and 3 samples of population controls from Western Pennsylvania consisting of a young cohort (N=473, aged 18-48 years), middle cohort (N=473, aged 42-50 years) and an old cohort (N=870, aged 65-90 years). The frequency of the APOE*4 allele was similar in the young and middle cohorts (0.12) and slightly lower in the old cohort (0.10). However, the frequency of the APOE*4 allele was three times higher in both early-onset (<65 years; 0.36) and late-onset ({ge}65 years; 0.38) sporadic AD cases compared to the control groups (p<0.0001). In the AD cohort the frequency of the APOE*4 allele was similar across all age groups (<65, 65-75, 76-85, 86+) and so was in men and women (0.40 vs. 0.37). The E*4 homozygosity was observed in 18% of AD cases compared to 1% in each of the three control groups. The E*4 heterozygosity was present in 50% of AD cases compared to 17% in the control old cohort and 22% in both the young and middle control cohorts. These data confirm that the APOE*4 allele is a major risk factor for AD regardless of age-at-diagnosis or family history.

  17. An epidemiological study on pattern of thoraco-abdominal injuries sustained in fatal road traffic accidents of Bangalore: Autopsy-based study

    2014-01-01

    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 planners to take safety measures, to implement strict traffic rules, to risk stratification in the susceptible population to educate the people, and the study of nature of offending agent in RTA can help the authorities to plan better availability of health care on roads.

  18. A social autopsy of neonatal mortality suggests needed improvements in maternal and neonatal interventions in Balaka and Salima districts of Malawi

    2015-06-01

    Full Text Available Background The Every Newborn Action Plan calls for reducing the neonatal mortality rates to fewer than 10 deaths per 1000 live births in all countries by 2035. The current study aims to increase our understanding of the social and modifiable factors that can be addressed or reinforced to improve and accelerate the decline in neonatal mortality in Malawi. Methods The data come from the 2013 Verbal and Social Autopsy (VASA study that collected data in order to describe the biological causes and the social determinants of deaths of children under 5 years of age in Balaka and Salima districts of Malawi. This paper analyses the social autopsy data of the neonatal deaths and presents results of a review of the coverage of key interventions along the continuum of normal maternal and newborn care and the description of breakdowns in the care provided for neonatal illnesses within the Pathway to Survival framework. Results A total of 320 neonatal deaths were confirmed from the VASA survey. While one antenatal care (ANC visit was high at 94%, the recommended four ANC visits was much lower at 41% and just 17% of the mothers had their urines tested during the pregnancy. 173 (54% mothers of the deceased newborns had at least one labor/delivery complication that began at home. The caregivers of 65% (n = 75 of the 180 newborns that were born at home or born and left a health facility alive perceived them to be severely ill at the onset of their illness, yet only 44% (n = 80 attempted and 36% (n = 65could reach the first health provider after an average of 91 minutes travel time. Distance, lack of transport and cost emerged as the most important constraints to formal care–seeking during delivery and during the newborn fatal illness. Conclusions This study suggests that maternal and neonatal health organizations and the local government of Malawi should increase the demand for key maternal and child health interventions, including the recommended 4 ANC visits, and ensure urine screening for all pregnant women. Early recognition and referrals of women with obstetric complications and interventions to promote maternal recognition of neonatal illnesses and care–seeking before the child becomes severely ill are also needed to improve newborn survival in Balaka and Salima districts of Malawi.

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

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. PMID:26110614

    Tattoos serve as a form of forensic personal identification and providing evidence of possible gang affiliation, incarceration history, and high-risk lifestyle factors such as drug use. Despite their forensic applications, tattoo typology and frequencies in specific ethnic and racial groups are underreported and poorly understood. This study examined autopsy records from the New Mexico Office of the Medical Investigator from 2002 to 2005. A total of 3430 individuals (1666 white Hispanics; 1764 white non-Hispanics), aged 18 to 100 years, with homicidal or accidental manners of death were included in the study. In addition to demographic information, data were recorded on the presence/absence of tattoos, singular or multiple tattoos, and the language of text tattoos. Tattoos depicting gang or religious symbolism were also recorded. Results indicate statistically significant differences in tattoo frequencies by ethnicity (52% Hispanic vs. 29.5% non-Hispanic), sex (46.8% men vs. 25.9% women) and age cohort. Hispanics were more likely to have multiple tattoos than non-Hispanics (41% and 19%, respectively), and were 4.67 times more likely to have a religious tattoo and 7.13 times more likely to have a gang tattoo than non-Hispanics. Significant patterns in language of text tattoos and correlations with manner of death were also noted. PMID:19259010

    Niger, one of the poorest countries in the world, recently used for the first time the integrated verbal and social autopsy (VASA) tool to assess the biological causes and social and health system determinants of neonatal and child deaths. These notes summarize the Nigerien experience in the use of this new tool, the steps taken for high level engagement of the Niger government and stakeholders for the wide dissemination of the study results and their use to support policy development and maternal, neonatal and child health programming in the country. The experience in Niger reflects lessons learned by other developing countries in strengthening the use of data for evidence-based decision making, and highlights the need for the global health community to provide continued support to country data initiatives, including the collection, analysis, interpretation and utilization of high quality data for the development of targeted, highly effective interventions. In Niger, this is supporting the country's progress toward achieving Millennium Development Goal 4. A follow-up VASA study is being planned and the tool is being integrated into the National Health Management Information System. VASA studies have now been completed or are under way in additional sub-Saharan African countries, in each through the same collaborative process used in Niger to bring together health policy makers, program planners and development partners.

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

    Jeong, Sanghyun

    2016-02-17

    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.

    Full Text Available Abstract Background The purpose of this study was to gain knowledge about the circumstances related to suicide among children and adolescents 15 years and younger. Methods We conducted a psychological autopsy, collecting information from parents, hospital records and police reports on persons below the age of 16 who had committed suicide in Norway during a 12-year period (1993-2004 (n = 41. Those who committed suicide were compared with children and adolescents who were killed in accidents during the same time period (n = 43 and with a community sample. Results: Among the suicides 25% met the criteria for a psychiatric diagnosis and 30% had depressive symptoms at the time of death. Furthermore, 60% of the parents of the suicide victims reported the child experienced some kind of stressful conflict prior to death, whereas only 12% of the parents of the accident victims reported such conflicts. Conclusion One in four suicide victims fulfilled the criteria for a psychiatric diagnosis. The level of sub-threshold depression and of stressful conflict experienced by youths who committed suicide did not appear to differ substantially from that of their peers, and therefore did not raise sufficient concern for referral to professional help.

    Atherosclerosis is a complex disease, involving both genetic and environmental factors. However, the influence of genetic variations on its early development remains unclear. This study examined the association of 12 different polymorphisms with atherosclerosis severity in anterior descending coronary (DA, n = 103) and carotid arteries (CA, n = 66) of autopsied young adults (projectile or car accident was the main cause of death, and no information about classical risk factors was available. 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-? 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-? (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. PMID:26674973

    Full Text Available Atrial septal defects (ASD are the most common congenital cardiac lesionin adults, representing up to 40% of acyanotic shunt lesions in patients olderthan 40 years. Secundum ASD comprises defects in the area of the ovalfossa, and may be associated with other types of interatrial communications.We present a case of a 25 year-old female patient who was asymptomaticuntil the age 22 when she started presenting exertion dyspnea and lowerlimbs edema, during her third pregnancy. The patient was admitted in theemergency department because of a febrile respiratory distress syndromedying in less than 36 hours after her arrival. The autopsy examination revealedpneumonia and a secundum ASD, associated with a rare form of interatrialcommunication, the inferior sinus venosus defect, which is characterized byan anomalous connection of the right pulmonary veins to the inferior caval veinat its opening in the right atrial cavity, while retaining partially their connectionto the left atrium. A dysplastic and thickened mitral valve was also present.Signs of pulmonary hypertension confirm the Eisenmenger syndrome in thisadult patient.

    This report concerns an autopsy case of atypical amyotrophic lateral sclerosis (ALS) with dementia mimicking frontal Pick's disease. The patient was a Japanese woman without hereditary burden who was 45 years old at the time of death. She developed abnormal behavior and amnesia at age 30, followed by disinhibition, aspontaneity, urinary incontinence, abulia, and rectal incontinence. Neurological signs compatible with ALS developed about 14 years after the disease onset. No respirator was used throughout the clinical course. Macroscopically, neuropathological examination showed atrophy of the frontotemporal lobes with accentuation in the convexities of the frontal lobes. Histologically, there was neuronal loss in the cerebral cortex, parahippocampal gyrus, amygdala, caudate nucleus, substantia nigra, brain stem motor nuclei, and anterior horns of the spinal cord, in addition to marked degeneration of the pyramidal tracts. Ubiquitin-immunoreactive neuronal inclusions were present in the frontotemporal cortical layer II neurons and motor neurons in the brain stem and spinal cord. In the hippocampal dentate granular cells, many ubiquitin-immunoreactive neurites were present without ubiquitin-immunoreactive intraneuronal inclusions. Based on these clinicopathological findings and a review of the literature, we concluded that our case was atypical ALS with dementia of long disease duration. We also note the possibility that motor neuron disease-inclusion dementia with a long clinical course may develop into ALS in the final stage of the illness. PMID:11515792

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

    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.

  12. Development of proton-induced x-ray emission techniques with application to multielement analyses of human autopsy tissues and obsidian artifacts

    A method of trace element analysis using proton-induced x-ray emission (PIXE) techniques with energy dispersive x-ray detection methods is described. Data were processed using the computer program ANALEX. PIXE analysis methods were applied to the analysis of liver, spleen, aorta, kidney medulla, kidney cortex, abdominal fat, pancreas, and hair from autopsies of Pima Indians. Tissues were freeze dried and low temperature ashed before analysis. Concentrations were tabulated for K, Ca, Ti, Mn, Fe, Co, Ni, Cu, Zn, Pb, Se, Br, Rb, Sr, Cd, and Cs and examined for significant differences related to diabetes. Concentrations of Ca and Sr in aorta, Fe and Rb in spleen and Mn in liver had different patterns in diabetics than in nondiabetics. High Cs concentrations were also observed in the kidneys of two subjects who died of renal disorders. Analyses by atomic absorption and PIXE methods were compared. PIXE methods were also applied to elemental analysis of obsidian artifacts from Campeche, Mexico. Based on K, Ba, Mn, Fe, Rb, Sr and Zr concentrations, the artifacts were related to several Guatemalan sources. (Diss. Abstr. Int., B)

    Cockayne syndrome presents senescence-like changes starting in early infancy; however, the mechanism of premature aging remains unclear. In an autopsy of a 23-year-old woman with Cockayne syndrome, we evaluated the correlation between Cockayne pathology and the expression patterns of the senescence-associated proteins p53 and Rb. Neuropathological findings in this case revealed basal ganglia calcification, tigroid leukodystrophy, bizarre reactive astrocytes, severe cerebellar atrophy with loss of Purkinje cells, and arteriolar/neuronal calcifications in the hypothalamus. Multiple arteriolar calcifications and sclerotic changes were seen in the central nervous system and kidney, but the endothelium of the aorta and coronary arteries remained intact appropriately for the individual's age without any finding of arteriosclerosis. Overexpression of p53 protein was confirmed in the cytoplasm of neurons in the basal ganglia, thalamus, hypothalamus, hippocampus and cerebellum, of arteriolar endothelial cells of the cerebrum and renal glomerular capillaries, and of cutaneous epithelial cells. The distribution of p53 overexpression was coincident with that of pathological alteration, such as neuronal loss, calcification and atrophy. High expression of p53 was localized in the cytoplasm, not in the nucleus. In contrast to p53, Rb was not expressed in any senescence lesion. In terms of senescence, distinct differences are found among organs in a patient with Cockayne syndrome. This segmental progeria differs from natural aging, and implicates p53 overexpression in the etiology of CS. PMID:25495205

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

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

    2014-03-01

    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. PMID:24457588

  15. An unusual autopsy case of incomplete decapitation of a motorcyclist with herniation of thoracic organs through a helmet-related neck wound.

    2013-12-01

    The authors report an unusual autopsy case of a motorcyclist who wore a full-face type helmet and had incomplete decapitation and herniation of the heart and a portion of the right lung through an extensive lacerate wound on the front of the neck after his motorcycle crashed. The authors identified 2 main offensive dynamics that occurred simultaneously: First, partial decapitation with a extensive gaping wound on the neck caused by the chin strap after a violent angular movement of the head; second, the translocation of the abdominal organs into the thorax and the herniation of the thoracic organs through the neck wound generated by a compressive trauma of the thorax and abdomen. This singular case, like few others in forensic literature, shows the possibility of helmet chin strap-related traumas and highlights the limitations of modern protective helmets. If the postulated mechanism is confirmed despite the massive benefits derived from the compulsory use of protective helmets, the properties of the helmet chin strap would need to be reassessed to improve the protection of the soft tissue and bones in the neck.

    Full Text Available OBJETIVO: Informar sobre el seguimiento de las directrices publicadas a comienzos de los años noventa con recomendaciones específicas para el diseño de los futuros estudios de vigilancia de la mortalidad basados en autopsias verbales. MÉTODOS: Llevamos a cabo una búsqueda sistemática de la bibliogra [...] fía para localizar todos los estudios basados en autopsias verbales publicados antes de enero de 2006 y extraer de ellos un conjunto estándar de datos. Para comparar los estudios diseñados antes y después de que se formularan las recomendaciones se emplearon siete indicadores metodológicos clave. RESULTADOS: Hallamos 102 estudios realizados en 39 países; 60 se habían diseñado antes de que se publicaran las directrices, y 42 después de su publicación. Se observaron diferencias considerables en los métodos utilizados por esos 102 estudios. Aunque se detectaron algunas tendencias alentadoras, no hay indicios de que se hayan aplicado sistemáticamente las recomendaciones en materia de diseño. Más concretamente, no aumentó claramente la proporción de estudios con un cuestionario combinado (63% antes de las recomendaciones frente a 74% después de las mismas; p = 0,3), un encuestador adiestrado (70% frente a 70%; p = 1,0), un encuestado idóneo (98% frente a 100%; p = 1,0), un periodo de rememoración óptimo (84% frente a 97%; p = 0,2), algoritmos predefinidos (28% frente a 38%; p = 0,4), una opción para asignar varias causas de defunción (30% frente a 38%; p = 0,3), o un estudio de validación de seguimiento (83% frente a 72%; p = 0,7). CONCLUSIÓN: Las recomendaciones formuladas por los expertos para optimizar el diseño de los estudios basados en autopsias verbales se han aplicado solo parcialmente hasta la fecha. Un mayor cumplimiento de ese tipo de recomendaciones gracias a una colaboración más idónea entre los equipos de investigación permitiría probablemente obtener mejores estadísticas de mortalidad a partir del creciente número de estudios basados en autopsias verbales. Abstract in english OBJECTIVE: To report on the uptake of guidelines published in the early 1990s with specific recommendations about the design of future studies based on verbal autopsy conducted for mortality surveillance. METHODS: We conducted a systematic literature search of all verbal autopsy studies published be [...] fore January 2006 and extracted from the studies a standard set of data. We then compared studies designed before and after the recommendations were issued in terms of seven key methodological indicators. FINDINGS: We found 102 studies conducted in 39 countries; 60 were designed before and 42 after the guidelines were issued. The methods used in these 102 studies varied considerably. While some encouraging trends were noted, there is no evidence that the design recommendations have been systematically implemented. Specifically, there was no clear increase in the proportion of studies with a combined questionnaire (63% before recommendations versus 74% after; P = 0.3), a trained interviewer (70% versus 70%; P = 1.0), a suitable respondent (98% versus 100%; P = 1.0), an optimal recall period (84% versus 97%; P = 0.2), predefined algorithms (28% versus 38%; P = 0.4), an option for assigning multiple causes of death (30% versus 38%; P = 0.3), or a follow-up validation study (83% versus 72%; P = 0.7). CONCLUSION: Expert recommendations for optimal design of verbal autopsy studies have been incompletely implemented to date. Better uptake of design recommendations through enhanced collaboration between research teams is likely to produce better mortality statistics from an increasing number of verbal autopsy studies.

    Full Text Available Abstract Background In resource- poor settings, verbal autopsy data are often reviewed by physicians in order to assign the probable cause of death. But in addition to being time and energy consuming, the method is liable to produce inconsistent results. The aim of this study is to evaluate the performance of the InterVA 3.2 model for establishing pulmonary tuberculosis as a cause of death in comparison with physician review of verbal autopsy data. Methods A population-based cross-sectional study was conducted from March to April, 2012. All adults aged ?14 years and died between 01 January 2010 and 15 February 2012 were included in the study. Data were collected by using a pre-tested and modified WHO designed verbal autopsy questionnaire. The verbal autopsy interviews were reviewed by the InterVA model and the physicians. Cohen’s kappa statistic, receiver operating characteristic curves, sensitivity, and specificity values were applied to compare the agreement between the InterVA model and the physician review. Results A total of 408 adult deaths were studied. The proportion of tuberculosis-specific mortality was established to be 36.0% and 23.0% by the InterVA model and the physicians, respectively. The InterVA model predicted pulmonary tuberculosis as a cause of death with the probability of 0.80 (95% CI: 0.75-0.85. In classifying all deaths as tuberculosis and non-tuberculosis, the sensitivity and specificity values were 0.82 and 0.78, respectively. A moderate agreement was found between the model and physicians in assigning pulmonary tuberculosis as a cause of deaths [kappa= 0.5; 95% CI: (0.4-0.6]. Conclusions This study has revealed that the InterVA model showed a more promising result as a community-level tool for generating pulmonary tuberculosis-specific mortality data from verbal autopsy. The conclusion is believed to provide policymakers with a highly needed piece of information for allocating resources for health intervention.

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.

    2011-08-01

    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. The causes for this trend are multiple and complex, encompassing religious, family and medical aspects. Among the latter, we highlight diagnostic reasons, which are characterized by major technological advances in clinical imaging associated with the underlying assumption that all diagnoses can currently be made before death. Furthermore, there is a growing concern about malpractice lawsuits. OBJECTIVE: To demonstrate the sharp decrease in the number of autopsies at a university hospital in Brazil. MATERIAL AND METHODS: We evaluated the number of autopsies conducted at the Pathology Department of Antonio Pedro University Hospital (HUAP, Niterói, Rio de Janeiro, and a database spreadsheet was created at Microsoft Excel. RESULTS: From 1966 to 2009, 23,813 autopsies were performed, comprising 12,702 adults and 11,111 fetuses. The highest number of autopsies occurred from 1966 to 1998, when 23,321 autopsies were performed, comprising 12,482 adults and 10,839 fetuses. Whereas, there was a dramatic decline from 1999 to 2009, when 492 autopsies were performed, including 220 adults and 272 fetuses. CONCLUSION: We believe that the main cause of this reduction is the lack of information among laypeople and medical professionals, who have neglected the fact that knowledge is ultimately acquired through study, investigation and practice.

    Full Text Available Introducción: El suicidio es un problema de salud pública relevante en Chile. Este es el primer estudio chileno con el método de la autopsia psicológica (AP). Objetivos: a) identificar factores de riesgo de suicidio en víctimas chilenas; b) identificar indicadores de riesgo para la intervención temp [...] rana; c) evaluar la aceptabilidad del método de la AP por los informantes. Método: La muestra consistió en 30 sujetos (24 hombres y 6 mujeres) que cometieron suicidio en la IV Región de Chile (diciembre de 2008-septiembre de 2010). La información fue recogida de entrevistas a informantes. El instrumento principal fue el Protocolo de Entrevista para Autopsia Psicológica. Resultados: La edad promedio fue 35,8 años. La mayoría comunicó intención suicida antes de consumarlo. Casi todos experimentaron eventos negativos, frecuentemente poco antes del suicidio. La mitad había intentado suicidarse previamente, algunos durante el mes precedente. El 36% estaba en tratamientos de salud mental al fallecer y un cuarto había visitado recientemente a profesionales de salud mental. Se identificó trastornos psiquiátricos (CIE-10) en el 90%, principalmente trastorno depresivo y por uso de sustancias. Los trastornos de personalidad fueron evidentes en ocho víctimas (33%): disocial (4), emocionalmente inestable (2), paranoide (1) y ansioso (evitativo) (1). Conclusiones: Se confirmó una elevada tasa de trastornos psiquiátricos. El antecedente de intentos previos es un predictor sensible de suicidio. La comunicación de intención suicida es frecuente y puede ser una oportunidad de intervención. El suicidio es frecuentemente precedido por eventos vitales negativos. La prevención del suicidio puede mejorar mediante el tratamiento efectivo de trastornos psiquiátricos e intervenciones psicosociales focalizadas. El seguimiento intensivo de intentadores parece altamente relevante. La AP es aceptable para los informantes. Abstract in english Background: Suicide is a relevant public health problem in Chile. This is the first Chilean study with the psychological autopsy method (PA). Aims: a) to identify risk factors for suicide in Chilean victims; b) to identify risk indicators for early intervention; c) to assess acceptability of the PA [...] method by informants. Method: Sample consisted of 30 subjects (24 males, six females) who commited suicide in the IV Region of Chile (December 2008-September 2010). Data was collected from informant interviews. Main instrument was the Psychological Autopsy Interview Protocol. Results: Mean age at suicide was 35.8 years. Most victims communicated suicidal intent before consummation. Almost all experienced negative life events, in many cases shortly before suicide. One half had attempted suicide previously, some during the preceding month. Thirty-six percent were in mental health treatments at time of death. A quarter had recently visited mental health professionals. Psychiatric disorders (ICD-10) were identified in 90%, mainly depressive and substance use disorders. Personality disorders were evident in eight victims (33%): dissocial (4), emotionally unstable (2), paranoid (1), and anxious (avoidant) (1). Conclusions: A high rate of psychiatric disorders was confirmed. Previous suicide attempts are sensitive predictors of completed suicide. Communication of suicide intent is frequent, and may be an opportunity for intervention. Suicide is often preceded by negative life events. Prevention of suicide may be improved by effective treatment of psychiatric disorders, and focused psychosocial interventions. Intensive follow-up of attempters seems highly relevant. PA is an acceptable method for informants.

    2010-06-01

    Full Text Available 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 resource-intensive process and is liable to produce inconsistent results. The aim of this paper is to explore how a computer-based probabilistic model, InterVA, performs in comparison with PR in interpreting VA data in the Nairobi Urban Health and Demographic Surveillance System (NUHDSS. Methods Between August 2002 and December 2008, a total of 1,823 VA interviews were reviewed by physicians in the NUHDSS. Data on these interviews were entered into the InterVA model for interpretation. Cause-specific mortality fractions were then derived from the cause of death data generated by the physicians and by the model. We then estimated the level of agreement between both methods using Kappa statistics. Results The level of agreement between individual causes of death assigned by both methods was only 35% (κ = 0.27, 95% CI: 0.25 - 0.30. However, the patterns of mortality as determined by both methods showed a high burden of infectious diseases, including HIV/AIDS, tuberculosis, and pneumonia, in the study population. These mortality patterns are consistent with existing knowledge on the burden of disease in underdeveloped communities in Africa. Conclusions The InterVA model showed promising results as a community-level tool for generating cause of death data from VAs. We recommend further refinement to the model, its adaptation to suit local contexts, and its continued validation with more extensive data from different settings.

    Background: Learning pathology is fundamental for a successful medical practice. In recent years, medical education has undergone a profound transformation toward the development of an integrated curriculum incorporating both basic science and clinical material. Simultaneously, there has been a shift from a magisterial teaching approach to one centered around problem-based learning. Now-a-days, informatics tools are expected to help better implement these strategies. Aim: We applied and evaluated a new teaching method based on an active combination of clinical problems, gross pathology, histopathology, and autopsy pathology, all given through informatics tools, to teach a group of medical students at the Universidad de Santander, Colombia. Design: Ninety-four medical students were followed in two consecutive semesters. Students were randomized to receive teaching either through traditional methodology or through the new integrated approach. Results: There was no significant difference between the intervention group and the control group at baseline. At the end of the study, the scores in the intervention group were significantly higher compared to the control group (3.91/5.0 vs. 3.33/5.0, P = 0.0008). Students and tutors endorsed the benefits of the integrated approach. Participants were very satisfied with this training approach and rated the program an 8.7 out of 10, on average. Conclusion: This study confirms that an integrated curriculum utilizing informatics systems provides an excellent opportunity to associate pathology with clinical medicine early in training of medical students. This can be possible with the use of virtual microscopy and digital imaging. PMID:25191624

  5. 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.

    2013-03-01

    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.

    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.

  7. Assessing the repeatability of verbal autopsy for determining cause of death: two case studies among women of reproductive age in Burkina Faso and Indonesia

    2009-05-01

    Full Text Available Abstract Background Verbal autopsy (VA is an established tool for assessing cause-specific mortality patterns in communities where deaths are not routinely medically certified, and is an important source of data on deaths among the poorer half of the world's population. However, the repeatability of the VA process has never been investigated, even though it is an important factor in its overall validity. This study analyses repeatability in terms of the overall VA process (from interview to cause-specific mortality fractions (CSMF, as well as specifically for interview material and individual causes of death, using data from Burkina Faso and Indonesia. Methods Two series of repeated VA interviews relating to women of reproductive age in Burkina Faso (n = 91 and Indonesia (n = 116 were analysed for repeatability in terms of interview material, individual causes of death and CSMFs. All the VA data were interpreted using the InterVA-M model, which provides 100% intrinsic repeatability for interpretation, and thus eliminated the need to consider variations or repeatability in physician coding. Results The repeatability of the overall VA process from interview to CSMFs was good in both countries. Repeatability was moderate in the interview material, and lower in terms of individual causes of death. Burkinabé data were less repeatable than Indonesian, and repeatability also declined with longer recall periods between the death and interview, particularly after two years. Conclusion While these analyses do not address the validity of the VA process in absolute terms, repeatability is a prerequisite for intrinsic validity. This study thus adds new understanding to the quest for reliable cause of death assessment in communities lacking routine medical certification of deaths, and confirms the status of VA as an important and reliable tool at the community level, but perhaps less so at the individual level.

  8. A lost cause? Extending verbal autopsy to investigate biomedical and socio-cultural causes of maternal death in Burkina Faso and Indonesia.

    Maternal mortality in developing countries is characterised by disadvantage and exclusion. Women who die whilst pregnant are typically poor and live in low-income and rural settings where access to quality care is constrained and where deaths, within and outside hospitals, often go unrecorded and unexamined. Verbal autopsy (VA) is an established method of determining cause(s) of death for people who die outside health facilities or without proper registration. This study extended VA to investigate socio-cultural factors relevant to outcomes. Interviews were conducted with relatives of 104 women who died during pregnancy, childbirth or postpartum in two rural districts in Indonesia and for 70 women in a rural district in Burkina Faso. Information was collected on medical signs and symptoms of the women prior to death and an extended section collected accounts of care pathways and opinions on preventability and cause of death. Illustrative quantitative and qualitative analyses were performed and the implications for health surveillance and planning were considered. The cause of death profiles were similar in both settings with infectious diseases, haemorrhage and malaria accounting for half the deaths. In both settings, delays in seeking, reaching and receiving care were reported by more than two-thirds of respondents. Relatives also provided information on their experiences of the emergencies revealing culturally-derived systems of explanation, causation and behaviour. Comparison of the qualitative and quantitative results suggested that the quantified delays may have been underestimated. The analysis suggests that broader empirical frameworks can inform more complete health planning by situating medical conditions within the socio-economic and cultural landscapes in which healthcare is situated and sought. Utilising local knowledge, extended VA has potential to inform the relative prioritisation of interventions that improve technical aspects of life-saving services with those that address the conditions that underlie health, for those whom services typically fail to reach.

    2005-03-01

    A 95-year-old woman complained of sudden onset of disturbance of consciousness and right hemiparesis on April 20, 2003 and was admitted on the next day. She was drowsy and showed moderate right motor and sensory hemiparesis. The blood laboratory tests showed slight inflammatory reaction. A low density area was found in the left basal ganglia by brain CT, which was also coincided with the high signal region in T2, FLAIR and diffusion-MR images. The MRA of the intracerebral arteries presented no remarkable abnormality. The hemiparesis and impaired consciousness improved partially in the following week. However, she did not fully recover, since aspiration pneumonia and mild generalized inflammation continued. Percutaneous gastrostomy and intravenous hyperalimentation were started to improve her nutrition. The moderate inflammatory state persisted for several weeks. Her blood pressure suddenly fell and she died on June 12. Autopsy showed a mildly brownish and necrotic lesion from the left caudate to the putamen through the internal capsule. There was no liquefaction. On the microscopic examination, the necrosis surrounded by small vessels was consisted of numerous neutrophils and macrophages with pseudohypha and blastospore of candida. Small fragments of fungus were phagocytosed by macrophages. Small abscesses and necrotic foci due to candidiasis were observed in the bladder, kidneys, lungs, myocardium and thyroid gland. In this case, cerebral candidiasis probably occurred via hematogenous dissemination from a primary focus in the urinary tract. The intracerebral arteries revealed rather mild atherosclerotic changes and there was no occlusion by thromboembolism. Intracerebral lesion was diagnosed as candidiasis and there was no cerebral infarction by thromboembolism. If the infection occurred after cerebral infarction, there should not be any inflammatory reaction in the center of necrotic area. There have been few reports of cerebral candidal infection in patients without diabetes mellitus or immunosuppressive conditions. None of them had been diagnosed before death. Caution should be exercised for the presence of systemic candidiasis in elderly patients who are bedridden and with continuous low grade inflammatory reactions. PMID:15835294

    2012-01-01

    We report on an autopsy case of corticobasal degeneration (CBD) with Lewy bodies in only the sympathetic ganglia. A 79-year-old man showed walking disturbance as an initial symptom, and developed dementia and bradykinesia within the next 2 years. Neurological examination revealed parkinsonism-like akinesia and rigidity in the trunk and neck without resting tremor. Brain magnetic resonance imaging showed frontal lobe atrophy predominantly on the right side. Cardiac uptake of meta-iodobenzylguanidine (MIBG) was reduced (H/M ratio: 1.14). A diagnosis of dementia with Lewy bodies (DLB) was made, but L-dopa treatment was not effective. Seven years later he died of pneumonia. On pathological examination, the frontal cortex and white matter were degenerated, predominantly on the right side. Gallyas-Braak silver staining and AT-8 immunostaining revealed neurofibrillary tangles, pretangles, argyrophilic threads, and astrocytic plaques in the cerebral cortex and basal ganglia, confirming the diagnosis of CBD. Lewy bodies, which were not seen in the central nervous system, were seen only in the sympathetic ganglia, and a severe loss of nerve fibers was apparent in the sympathetic nerve endings in the heart. MIBG is currently used to differentiate DLB from other parkinsonisms, such as CBD, multiple system atrophy, and progressive supranuclear palsy, because reduced cardiac uptake of MIBG represents a pathological change in the sympathetic nerve endings in the heart. However, the distribution of Lewy bodies cannot be determined from this finding. Thus, MIBG should not be used alone to confirm a diagnosis of DLB; other neurodegenerative diseases with incidental Lewy body disease, as in the present case, must be also considered. PMID:22790801

    A 59-year-old man with a long history of under-treated diabetes mellitus presented with severe inflammation that had spread from the sinus to the left orbital cavity. The bilateral internal carotid arteries were severely stenotic, causing multiple infarctions in the brain parenchyma. There was no ?-D-glucan detected in the cerebrospinal fluid. Based on the presence of central nervous system (CNS) inflammation and vascular involvements that spread from the sinusitis, we tentatively diagnosed this patient as having invasive fungal CNS infection, i.e. zygomycosis or aspergillosis. Although the patient was treated with anti-fungal drugs such as liposomal amphotericin B and voriconazole, he died of respiratory failure. Pathological examination of the autopsied tissues demonstrated zygomycosis in the brain and heart. The prevalence of zygomycosis is generally very low (-5% of CNS infections) compared with that of other fungal infections. The lack of an appropriate diagnostic marker may lead to the under- or mis-diagnosis of zygomycosis. Moreover, it is hard to differentiate zygomycosis from aspergillosis because the two diseases share common clinical features such as the association of sinusitis and vascular involvement. The clinically diagnostic points that discriminate zygomycosis from aspergillosis are as followed; i) ?-D-glucan is negative in zygomycosis but positive in aspergillosis; ii) diabetes is more frequent in patients with zygomycosis to those with aspergillosis; iii) the infectious lesion in aspergillosis shows an iso-low-intensity on T(2) weighted MRI image but shows a high intensity lesion in zygomycosis. The mortality rate of CNS zygomycosis is so high that an early diagnosis of it is warranted and the start appropriate anti-fungal treatments or surgical drainage in the early stage of the disease.

    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.

    2011-08-01

    Full Text Available Abstract Background Verbal autopsy (VA can be used to describe leading causes of death in countries like Zambia where vital events registration does not produce usable data. The objectives of this study were to assess the feasibility of using verbal autopsy to determine age-, sex-, and cause-specific mortality in a community-based setting in Zambia and to estimate overall age-, sex-, and cause-specific mortality in the four provinces sampled. Methods A dedicated census was conducted in regions of four provinces chosen by cluster-sampling methods in January 2010. Deaths in the 12-month period prior to the census were identified during the census. Subsequently, trained field staff conducted verbal autopsy interviews with caregivers or close relatives of the deceased using structured and unstructured questionnaires. Additional deaths were identified and respondents were interviewed during 12 months of fieldwork. After the interviews, two physicians independently reviewed each VA questionnaire to determine a probable cause of death. Results Among the four provinces (1,056 total deaths assessed, all-cause mortality rate was 17.2 per 1,000 person-years (95% confidence interval [CI]: 12.4, 22. The seven leading causes of death were HIV/AIDS (287, 27%, malaria (111, 10%, injuries and accidents (81, 8%, diseases of the circulatory system (75, 7%, malnutrition (58, 6%, pneumonia (56, 5%, and tuberculosis (50, 5%. Those who died were more likely to be male, have less than or equal to a primary education, and be unmarried, widowed, or divorced compared to the baseline population. Nearly half (49% of all reported deaths occurred at home. Conclusions The 17.2 per 1,000 all-cause mortality rate is somewhat similar to modeled country estimates. The leading causes of death -- HIV/AIDS, malaria, injuries, circulatory diseases, and malnutrition -- reflected causes similar to those reported for the African region and by other countries in the region. Results can enable the targeting of interventions by region, disease, and population to reduce preventable death. Collecting vital statistics using standardized Sample Vital Registration with Verbal Autopsy (SAVVY methods appears feasible in Zambia. If conducted regularly, these data can be used to evaluate trends in estimated causes of death over time.

    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. Cost, including for transport, health care and other expenses, emerged as main barriers to formal care–seeking both for the mothers and their newborns. Conclusions This study presents an opportunity to strengthen maternal and newborn health by increasing the coverage of essential and low cost interventions that could have saved the lives of many newborns in eastern Cameroon.

    We describe an autopsy case of basophilic inclusion body disease (BIBD), a subtype of frontotemporal lobar degeneration (FTLD) with the appearance of fused in sarcoma (FUS) inclusions (FTLD-FUS), clinically presenting corticobasal syndrome (CBS). A 54-year-old man initially developed worsening of stuttering and right hand clumsiness. Neurological examinations revealed rigidity in the right upper and lower extremities, buccofacial apraxia, and right-side dominant limb-kinetic and ideomotor apraxia. Neuroimaging showed asymmetric left-dominant brain atrophy and a cerebral blood flow reduction in the ipsilateral frontal region. At 56 years, his apraxia had advanced, and ideational apraxia was observed. Furthermore, the asymmetry in the limb-kinetic and ideomotor apraxia had disappeared, and both conditions had become bilateral. He had a new onset of aphasia. His symptoms progressed and he died 9 years after the initial symptoms. The brain weighed 955 g. Diffuse brain atrophy was most obvious in the bilateral frontotemporal regions. The atrophy of the left superior frontal and precentral gyri and bilateral basal ganglia was remarkable. Histologically, there was a marked loss of neurons with gliosis in the affected areas, where basophilic neuronal cytoplasmic inclusions were observed. The inclusions were immunoreactive for FUS, p62, and TATA-binding protein-associated factor 15 (TAF15), but not for phosphorylated tau, transactive response DNA-binding protein of 43 kDa (TDP-43), neurofilament protein, or Ewing sarcoma (EWS). From these pathological findings, this case was diagnosed as having BIBD as an FTLD-FUS variant. Spinal cord lower motor neurons were spared in number, similar to primary lateral sclerosis. Mutations in FUS were undetectable. Common background pathologies for CBS include corticobasal degeneration, Alzheimer's disease, PSP, FTLD with phosphorylated TDP-43 inclusions (FTLD-TDP), Pick's disease, Lewy body disease and CJD. However, FTLD-FUS (BIBD) has been rarely reported. Our case suggested further pathological heterogeneity in CBS than had previously been reported. It is necessary to consider FTLD-FUS (BIBD) as a background pathology for CBS in the future. PMID:26227957

    Full Text Available Background To accelerate progress toward the Millennium Development Goal 4, reliable information on causes of child mortality is critical. With more national verbal autopsy (VA studies becoming available, how to improve consistency of national VA derived child causes of death should be considered for the purpose of global comparison. We aimed to adapt a standardized computer algorithm to re–analyze national child VA studies conducted in Uganda, Rwanda and Ghana recently, and compare our results with those derived from physician review to explore issues surrounding the application of the standardized algorithm in place of physician review. Methods and Findings We adapted the standardized computer algorithm considering the disease profile in Uganda, Rwanda and Ghana. We then derived cause–specific mortality fractions applying the adapted algorithm and compared the results with those ascertained by physician review by examining the individual– and population–level agreement. Our results showed that the leading causes of child mortality in Uganda, Rwanda and Ghana were pneumonia (16.5–21.1% and malaria (16.8–25.6% among children below five years and intrapartum–related complications (6.4–10.7% and preterm birth complications (4.5–6.3% among neonates. The individual level agreement was poor to substantial across causes (kappa statistics: –0.03 to 0.83, with moderate to substantial agreement observed for injury, congenital malformation, preterm birth complications, malaria and measles. At the population level, despite fairly different cause–specific mortality fractions, the ranking of the leading causes was largely similar. Conclusions The standardized computer algorithm produced internally consistent distribution of causes of child mortality. The results were also qualitatively comparable to those based on physician review from the perspective of public health policy. The standardized computer algorithm has the advantage of requiring minimal resources from the health care system and represents a promising way to re–analyze national or sub-national VA studies in place of physician review for the purpose of global comparison.

    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-automated coding of VA to determine CoD reconfirmed that NCDs were the leading CoD with some differences between the sites. Incorporating VA into the national sample vital registration system can help policy makers to identify the leading CoDs for public health planning.

    Full Text Available OBJETIVO: Analisar a concordância entre os diagnósticos clínicos e os achados anatomopatológicos obtidos por meio do exame necroscópico, a fim de determinar a freqüência com que a necropsia revela diagnósticos principais inesperados, que são relevantes para a causa do óbito. MÉTODOS: Foram analisadas retrospectivamente 680 necropsias realizadas no Hospital de Base do Distrito Federal (HBDF, de janeiro de 1997 a dezembro de 2002. Para a comparação entre os achados clínicos e anatomopatológicos utilizou-se a classificação de Goldman, e fez-se a correlação segundo o sexo, a idade do paciente, a unidade de internação e o tempo de permanência hospitalar. Foram utilizados, como fonte de dados, os pedidos de necropsia, preenchidos pelos médicos-assistentes, e os laudos finais de necropsia. RESULTADOS: A necropsia confirmou os diagnósticos principais formulados pela clínica em 69% das amostras. Em relação aos casos discordantes, 18% foram classificados como classe I (com potencial impacto na sobrevida do paciente e 13% como classe II (sem o questionável impacto na sobrevida do paciente. Os principais diagnósticos discordantes mais freqüentes foram doenças do aparelho circulatório (acidente vascular cerebral, insuficiência cardíaca congestiva e miocardiopatia hipertrófica, moléstias infecciosas (meningite bacteriana, tuberculose miliar e neurotoxoplasmose e neoplasias (linfomas. CONCLUSÕES: Evidenciou-se significativa discordância entre os diagnósticos clínicos e anatomopatológicos post mortem, mostrando que a necropsia ainda é um procedimento importante para o esclarecimento diagnóstico, bem como para a melhoria dos serviços de saúde.OBJECTIVE: To analyze the discrepancies between clinical and postmortem diagnoses in order to determine the frequency of relevant missed diagnoses detected at autopsy. METHOD: Six hundred and eighty patients autopsied at the Hospital de Base do Distrito Federal, Brazil, between January 1997 and December 2002 were retrospectively investigated. Agreement between clinical and postmortem findings was compared using Goldman's system. Medical records and final autopsy reports were reviewed. RESULTS: Major clinical diagnoses were confirmed in 69% of analyzed autopsies. Eighteen percent of cases were classified as Goldman class I missed diagnosis (if known before death, might have led to prolonged survival and 13% as class II (clinically missed major diagnosis for which survival would not have been changed. Most frequent missed major diagnoses were cardiovascular diseases (cerebral hemorrhagic infarction, congestive heart failure and hypertrophic cardiomyopathy, infectious diseases (purulent meningitis, miliar tuberculosis and neurotoxoplasmosis and neoplasia (lymphoma. CONCLUSION: This study has found significant disagreement between clinical and postmortem examinations and reinforces the importance of autopsy in improving clinical diagnosis and in providing data that could be integrated in quality assurance programs.

Há escassos estudos de autopsia com análise detalhada desse sistema e apenas um deles foi realizado no Brasil. Nest [...] e estudo avaliamos cada segmento do sistema digestório em 93 autopsias consecutivas de indivíduos infectados pelo vírus da imunodeficiência humana (HIV) e a importância dessas lesões para o óbito. Desses, 90 (96,8%) pacientes apresentavam AIDS. Revisamos prontuários médicos, relatórios de autopsias e cortes histológicos da língua ao reto corados pela técnica de hematoxilina-eosina. Quando necessário, analisamos colorações especiais e imuno-histoquímica para pesquisar infecções. Havia lesões no sistema digestório em 73 (78,5%) casos. As alterações mais comuns foram infecciosas: candidíase (42%), citomegalovirose (29%), histoplasmose (11,8%), toxoplasmose (9,7%) e infecção por micobactérias (9,7%). Neoplasias malignas foram raras, presentes em quatro (4,3%) casos (dois sarcomas de Kaposi, um adenocarcinoma gástrico e um carcinoma embrionário metastático). Todos os segmentos apresentaram lesões: língua (48,6%), esôfago (44,8%), estômago (44,7%), intestino grosso (43,2%) e intestino delgado (28,9%). As lesões encontradas foram causa imediata do óbito em cinco (5,4%) casos. Em outros 36 (38,7%) casos a doença básica era sistêmica comprometendo, também, o sistema digestório.

    Full Text Available OBJETIVOS: Apresentar alterações histopatológicas pulmonares encontradas em autopsias de pacientes falecidos por insuficiência respiratória aguda (IRA e verificar se doenças de base e específicos fatores de risco associados aumentam a incidência dessas alterações. MÉTODOS: Foram revisados laudos finais de autopsias e selecionadas 3.030 autopsias de pacientes > 1 ano de idade, com infiltrado pulmonar radiológico, portadores de doença de base e fatores de risco associados, que morreram por alterações pulmonares decorrentes de IRA. RESULTADOS: As principais alterações histopatológicas pulmonares causadoras de morte imediata foram: dano alveolar difuso (DAD; edema pulmonar; pneumonia intersticial linfocítica (PIL e hemorragia alveolar. As principais doenças de base encontradas foram: AIDS; broncopneumonia; sepse; cirrose hepática; tromboembolismo pulmonar; infarto agudo do miocárdio (IAM; acidente vascular cerebral; tuberculose; câncer; insuficiência renal crônica e leucemia. Os principais fatores de risco associados foram: idade > 50 anos; hipertensão arterial; insuficiência cardíaca congestiva; doença pulmonar obstrutiva crônica e diabetes mellitus. Pacientes com esses fatores de risco e AIDS apresentaram alta probabilidade de desenvolver PIL; pacientes com esses mesmos fatores, de desenvolver DAD, se portadores de sepse ou cirrose hepática; pacientes com tromboembolismo e os mesmos fatores de risco, de desenvolver hemorragia alveolar; pacientes com esses fatores de risco e IAM, de desenvolver edema pulmonar. CONCLUSÕES: Os achados pulmonares em pacientes com óbito por IRA apresentaram quatro padrões histopatológicos: DAD, edema pulmonar, PIL e hemorragia alveolar. Doenças de base e específicos fatores de risco associados correlacionaram-se positivamente com determinados padrões histopatológicos detectados à autópsia.OBJECTIVE: To present the pulmonary histopathological alterations found in the autopsies of patients with acute respiratory failure (ARF and determine whether underlying diseases and certain associated risk factors increase the incidence of these histopathological patterns. METHODS: Final autopsy reports were reviewed, and 3030 autopsies of patients > 1 year of age with an underlying disease and associated risk factors were selected. All had developed diffuse infiltrates and died of ARF-related pulmonary alterations. RESULTS: The principal pulmonary histopathological alterations resulting in immediate death were diffuse alveolar damage (DAD, pulmonary edema, lymphocytic interstitial pneumonia (LIP and alveolar hemorrhage. The principal underlying diseases were AIDS, bronchopneumonia, sepsis, liver cirrhosis, pulmonary thromboembolism, acute myocardial infarction (AMI, cerebrovascular accident, tuberculosis, cancer, chronic kidney failure and leukemia. The principal associated risk factors were as follows: age > 50 years; arterial hypertension; congestive heart failure; chronic obstructive pulmonary disease; and diabetes mellitus. These risk factors and AIDS correlated with a high risk of developing LIP; these same risk factors, if concomitant with sepsis or liver cirrhosis, correlated with a risk of developing DAD; thromboembolism and these risk factors correlated with a risk of developing alveolar hemorrhage; these risk factors and AMI correlated with a risk of developing pulmonary edema. CONCLUSION: Pulmonary findings in patients who died of ARF presented four histopathological patterns: DAD, pulmonary edema, LIP and alveolar hemorrhage. Underlying diseases and certain associated risk factors correlated positively with specific histopathological findings on autopsy.

    Pursuant to the Polish Weapons and Ammunitions Law, muzzle-loading black powder weapons, manufactured before 1885, or their replicas, as well as suitable projectiles, can be possessed legally without registration and special licenses. The aim of the study was to assess the penetration depth of projectiles fired from a black powder weapon, replica of Colt Navy of 1851, in 20% gelatin blocks and to compare the obtained results with the actual injuries found on autopsy of a 78-year-old man who had committed suicide. In the experiments, we used the black powder weapon and ammunitions, as well as gelatin blocks serving as a soft tissue model. We ascertained that solid spherical projectiles fired from black powder weapons cause extensive injuries, especially in the initial segment of the wound canal. Additionally, based on the presence and location of the wad in the wound canal, the distance from which the shot was fired can be determined. PMID:25864492

  7. Affinities and densities of high-affinity [3H]muscimol (GABA-A) binding sites and of central benzodiazepine receptors are unchanged in autopsied brain tissue from cirrhotic patients with hepatic encephalopathy

    The integrity of GABA-A receptors and of central benzodiazepine receptors was evaluated in membrane preparations from prefrontal cortex and caudate nuclei obtained at autopsy from nine cirrhotic patients who died in hepatic coma and an equal number of age-matched control subjects. Histopathological studies revealed Alzheimer Type II astrocytosis in all cases in the cirrhotic group; controls were free from neurological, psychiatric or hepatic diseases. Binding to GABA-A receptors was studied using [3H]muscimol as radioligand. The integrity of central benzodiazepine receptors was evaluated using [3H]flunitrazepam and [3H]Ro15-1788. Data from saturation binding assays was analyzed by Scatchard plot. No modifications of either affinities (Kd) or densities (Bmax) of [3H]muscimol of central benzodiazepine binding sites were observed. These findings do not support recent suggestions that alterations of either high-affinity GABA or benzodiazepine receptors play a significant role in the pathogenesis of hepatic encephalopathy

    Full Text Available Esse estudo analisa autópsias psicológicas e contextualiza problemas e fatores que levaram algumas pessoas idosas a acabar com a própria vida na cidade do Rio de Janeiro, entre 2004 e 2007. 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. 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.

    Full Text Available Se presentaron los resultados de 5 investigaciones realizadas en niños y jóvenes, para demostrar que existen desde las primeras edades de la vida una serie de señales aterogénicas tempranas posibles de detectar; las que conocidas obligan a tomar medidas médicas y socioculturales que permitan evitar o retardar el desarrollo de la aterosclerosis. Se estudiaron niños y adolescentes entre 5 y 16 años de 6 escuelas de Ciudad de La Habana, 2 de Panamá, 1 de Concepción, Chile, y 3 de Itapetininga, Brasil. También se investigaron la aorta y la arteria coronaria derecha procedentes de las autopsias de un estudio multinacional dirigido por la Organización Mundial de la Salud, donde participaron 18 países de 4 continentes, se investigaron niños y jóvenes de edades entre 5 y 34 años, todos fallecidos por muerte violenta. Se presentaron los resultados de los estudios patomorfológicos y morfométricos, utilizando el sistema aterométrico . Se estudió el impacto de 3 factores de riesgo, hipertensión arterial, diabetes mellitus tipo 2 y tabaquismo en la producción de lesiones ateroscleróticas. Las conclusiones más relevantes fueron las siguientes: 1. Sí existen suficientes señales aterogénicas tempranas, como hipertensión arterial, obesidad, circunferencia de la cintura exagerada, el índice de masa corporal alterado, tabaquismo activo y pasivo, y los antecedentes patológicos familiares de padecer alguna enfermedad relacionada con la aterosclerosis. 2. Como elementos discriminatorios para la identificación de los niños y jóvenes en los distintos países las variables más relevantes fueron el peso corporal, la circunferencia de la cintura y los valores de tensión arterial sistólica y diastólica. 3. En los estudios de autopsia se pudo demostrar el incremento de áreas de íntima ocupada por lesiones ateroscleróticas con el progreso de la edad y el gran efecto que la hipertensión, la diabetes mellitus tipo 2 y el tabaquismo ejercen en el desarrollo de la aterosclerosis y la transformación de las estrías adiposas en placas fibrosasThe results of 5 researches conducted among children and youth were presented to prove that there exists a series of early atherogenic signals since the first ages of life that are possible to detect and that once known oblige to take some medical and sociocultural measures that allow to prevent or delay the development of atherosclerosis. Children and adolescents aged 5-6 from 6 schools of Havana City , 2 from Panama , 1 from Concepción , Chile , and 3 from Itapetininga , Brazil , were studied. The aorta and the right coronary artery from the autopsies of a multinational study directed by the World Health Organization were also investigated. 18 countries from 4 continents took part in this study, in which children and youth aged 5-34 were studied. All of them had had a violent death. The results of the pathomorphological and morphometric studies were presented by using the atherometric system. The impact of 3 risk factors, arterial hypertension, type 2 diabetes mellitus and smoking on the production of atherosclerotic lesions, was studied. The most relevant conclusions were: 1. There are enough early atherogenic signals, such as arterial hypertension, obesity, exaggerated hip circumference, altered body mass index, active and passive smoking and the family pathological history of suffering from some disease related to atherosclerosis. 2. As discriminatory elements for the identification of children and youth in the different countries, the most significant variables were body weight, hip circumference and the values of systolic and diastolic arterial pressure. 3. In the autopsy studies, it was proved the increase of intima areas occupied by atherosclerotic lesions with the progress of age and the great effect that hypertension , type 2 diabetes mellitus and smoking exert on the development of atherosclerosis and the transformation of the adipose striae into fibrous plaques

    Full Text Available Background: The vast majority of deaths in the Kilifi study area are not recorded through official systems of vital registration. As a result, few data are available regarding causes of death in this population. Objective: To describe the causes of death (CODs among residents of all ages within the Kilifi Health and Demographic Surveillance System (KHDSS on the coast of Kenya. Design: Verbal autopsies (VAs were conducted using the 2007 World Health Organization (WHO standard VA questionnaires, and VA data further transformed to align with the 2012 WHO VA instrument. CODs were then determined using the InterVA-4 computer-based probabilistic model. Results: Five thousand one hundred and eighty seven deaths were recorded between January 2008 and December 2011. VA interviews were completed for 4,460 (86% deaths. Neonatal pneumonia and birth asphyxia were the main CODs in neonates; pneumonia and malaria were the main CODs among infants and children aged 1–4, respectively, while HIV/AIDS was the main COD for adult women of reproductive age. Road traffic accidents were more commonly observed among men than women. Stroke and neoplasms were common CODs among the elderly over the age of 65. Conclusions: We have established the main CODs among people of all ages within the area served by the KHDSS on the coast of Kenya using the 2007 WHO VA questionnaire coded using InterVA-4. We hope that our data will allow local health planners to estimate the burden of various diseases and to allocate their limited resources more appropriately.

    Prototype cable-in-conduit-conductors (CICCs) destined for use in the toroidal field and central solenoid coils of the ITER experimental fusion reactor underwent severe cyclic loading in the SULTAN facility. Their autopsies revealed significant and permanent transverse strand migration due to the large Lorentz forces of the SULTAN test. The movement resulted in a 3%-7% void fraction increase on the low pressure (LP) side of the longer twist pitch CICCs. However, short twist pitch conductors exhibited less than 1% void fraction increase in the LP side, as well as a complete absence of the Nb3Sn filament fractures observed in the longer twist pitch conductors. We report here a detailed strand-to-cable analysis of short and longer ‘baseline’ twist pitch CICCs. It was found that the use of internal tin (IT) strands in the longer ‘baseline’ twist pitch CICCs can be beneficial possibly because of their superior stiffness—which better resist strand movement—while the use of bronze process strands showed more movement and poorer cyclic test performance. This was not the case for the short twist pitch CICC. Such conductor design seems to work well with both strand types. But it was found that despite the absence of filament fractures, the short twist pitch CICC made from the IT strands studied here developed severe strand distortion during cabling which resulted in diffusion barrier breaks and Sn contamination of the Cu stabilizer during the heat treatment. Conversely, the short twist pitch CICC made from bronze process strands preserved diffusion barrier integrity.

    Full Text Available Atherosclerosis is a complex disease, involving both genetic and environmental factors. However, the influence of genetic variations on its early development remains unclear. This study examined the association of 12 different polymorphisms with atherosclerosis severity in anterior descending coronary (DA, n = 103 and carotid arteries (CA, n = 66 of autopsied young adults (<30 years old. Histological sections (H-E were classified according to the American Heart Association. Polymorphisms in ACE, TNF-α (−308G/A and −238 G/A, IFN-γ (+874 A/T, MMP-9 (−1562 C/T, IL-10 (−1082 A/G and −819 C/T, NOS3 (894 G/T, ApoA1 (rs964184, ApoE (E2E3E4 isoforms, and TGF-β (codons 25 and 10 genes were genotyped by gel electrophoresis or automatic DNA sequencing. Firearm projectile or car accident was the main cause of death, and no information about classical risk factors was available. 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.

  15. Evaluation of image quality and spatial resolution of low-dose high-pitch multidetector-row helical high-resolution CT in 11 autopsy lungs and a wire phantom

    The aim of this study was to evaluate whether low-dose high-pitch (6:1) multidetector-row helical high-resolution CT is appropriate for the evaluation of various pulmonary abnormalities, including faint opacities. Eleven autopsy lungs were scanned with a multidetector-row CT scanner using 2.5 mm x 4 beam collimation, effective slice thickness 3 mm, 6:1 pitch, 0.8 second gantry rotation speed, 20 cm Display Fov, high spatial frequency (bone) algorithm, and various radiation doses (120 kVp; 160, 80, 40, 24, and 8 mAs). The image quality of each CT set was assessed as adequate or inadequate for diagnosis by two independent observers. In addition, a wire phantom was scanned with the same parameters in order to describe the modular transfer function (MTF) curves. There was excellent agreement between the observers for the evaluation of image quality (kappa statistic, 0.84). The ratio of images evaluated as inadequate for 8 mAs and 24 mAs was significantly higher than that for 160, 80, and 40 mAs (p<0.01: chi-square test). MTF curves of both 8 and 24 mAs were significantly inferior to those of 40, 80, and 160 mAs (p<0.01, Friedman test), while the MTF curve of 40 mAs was relatively inferior to that of 160 mAs (p<0.05, Friedman test). More than 40 mAs in combination with 120 kVp is preferable for the evaluation of details of lung parenchyma by high-pitch. multidetector-row helical high-resolution CT. (author)

    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 thromboembolism was associated with an appreciable risk of death (OR = 2.4 in patients with arterial hypertension. The risk of death was also high in patients presenting hepatic cancer (OR = 2.5 or steroid therapy (OR = 2.4 who developed pulmonary hemorrhage as the histological pattern of secondary interstitial pneumonia . The risk of death by lung metastasis was also elevated (OR = 1.6 for patients that were immunosuppressed after radiotherapy. CONCLUSION: Patients with secondary immunosuppression who developed secondary interstitial pneumonia during treatment in hospital should be evaluated to avoid death by diffuse alveolar damage, pulmonary edema, bronchopneumonia, lung hemorrhage, pulmonary thromboembolism, or lung metastasis. The high-risk patients are those immunosuppressed by hematologic disease; those under steroid treatment; or those with colon or hepatic carcinoma, cachexia, or arterial hypertension.OBJETIVO: Apresentar as associações mais freqüentes encontradas em autópsias de pacientes imunossuprimidos que desenvolveram pneumonia intersticial secundária bem como o risco de óbito (Odds Ratio de desenvolver PIS associada à causa da imunossupressão. MÉTODO: De janeiro de 1994 a março de 2004, 17000 autópsias foram realizadas no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. A partir da revisão dos laudos patológicos foram selecionados 558 destas autópsias (3,28% de pacientes com 15 anos de idade ou mais, com alguma doença de base que desenvolveu um infiltrado pulmonar radiologicamente difuso durante o curso da hospitalização e que depois foi para óbito com pneumonia intersticial secundária (broncopneumonia, pneumonia lobar, pneumonia intersticial, dano alveolar difuso, doença pulmonar recorrente, doença pulmonar induzida por drogas, edema pulmonar cardiogênico e embolismo pulmonar. As lâminas histológicas foram revisadas por patologistas experientes para confirmar ou não a presença de pneumonia intersticial secundária. A análise estatística incluiu o "Teste exato de Fisher" para verificar associação entre a histolopatologia e causa de imunocomprometimento; e regressão logística para predizer o risco de óbito por achados histológicos específicos para cada variável independente do modelo. RESULTADOS: A pneumonia intersticial secundária foi representada histológicamente por pneumonite intersticial difusa variando de características não especificas leves (n=213 ao padrão histológico de dano alveolar difuso (n=273. A principal causa de imunossupressão nos pacientes com dano alveolar difuso foi sepse (136 casos, neoplasia (113 casos, diabetes melito (37 casos e transplantados (37 casos. O maior risco de morte por edema pulmonar foi encontrado nos pacientes com carcinoma de cólon. Da mesma forma, nos pacientes com câncer pulmonar ou cachexia ocorreu um alto risco de morte (OR=3.6; OR=2.6, respectivamente por broncopneumonia. O tromboembolismo pulmonar ofereceu um importante risco de morte (OR=2.4 nos pacientes com hipertensão arterial. Observou-se também risco de morte por câncer hepático (OR=2.5 ou terapia esteroidea (OR=2.4 nos pacientes que desenvolveram hemorragia pulmonar com padrão histológico de pneumonia intersticial secundária. Da mesma forma houve alto risco de morte por metástase pulmonar (OR= 1.6 nos pacientes imunossuprimidos após radioterapia. CONCLUSÃO: Pacientes com imunossupressão secundária que desenvolveram pneumonia intersticial secundária durante o tratamento dentro do hospital podem ser avaliados para evitar como evento final o dano alveolar difuso, o edema pulmonar, a broncopneumonia, a hemorragia pulmonar, o tromboembolismo pulmonar e a metástase pulmonar. Os pacientes com aumento de risco são aqueles imunossuprimidos por doença hematológica, sob tratamento com esteroides, carcimona hepático, cachexia e hipertensão.

  19. Glycoprotein IIIa Pl(A) polymorphism associates with progression of coronary artery disease and with myocardial infarction in an autopsy series of middle-aged men who died suddenly.

    Glycoprotein IIIa (GPIIIa) has a key role in the aggregation of thrombocytes, and it also mediates intimal hyperplasia after endothelial injuries; the possible association of the Pl(A1/A2) polymorphism of the gene for GPIIIa with coronary thrombosis and with the progression of coronary artery disease (CAD) is still to be confirmed. Therefore, the association of the Pl(A) polymorphism with the development of coronary atherosclerosis, coronary narrowing, and myocardial infarction (MI) was studied in a prospective, consecutive autopsy series of 300 middle-aged, white Finnish men (33 to 69 years) suffering sudden out-of-hospital or violent death. Coronary atherosclerosis was measured morphometrically and the coronary stenosis percentage determined from a cast rubber model of the coronary tree. We found a significant inverse relation (P=0.01) between the Pl(A2)-positive genotype and coronary artery stenosis. The frequency of possessing the Pl(A2) allele was significantly (odds ratio [OR] 0.45, 95% confidence interval [CI] 0.22 to 0.98) lower among men with >50% coronary stenosis (18.3%) than among those with <25% stenosis (32.9%). Although the Pl(A) polymorphism was not directly associated with MI, the Pl(A2) allele was present in 11 of the 22 men (50%) with MI and coronary thrombosis (OR 6.6, 95% CI 2.1 to 22.8) but in only 6 of the 47 (12.8%) with MI associated with severe stenosis in the absence of thrombosis. In line with this result, men possessing the Pl(A2) allele also had a larger area of fissured and ulcerated complicated lesions in their coronary arteries (P<0.05). The present results suggest that the Pl(A) polymorphism is involved in the development of CAD and MI. Men with the Pl(A2) allele may harbor more thin-walled, vulnerable coronary plaques, plaques prone to rupture, leading to massive, fatal thrombosis. In contrast, men homozygous for the Pl(A1) allele may more often show stable plaques and present with infarction caused by progressive coronary stenosis. PMID:10521390

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. Autópsia foi realizada em todos os casos. As idades variaram de 3 a 81 anos. Todos foram agredidos por cães. O tempo entre o acidente e a admissão hospitalar variou de 20 a 120 dias (média de 45 ± 34 dias. O tempo de internamento variou de 1 a 9 dias (média de 5.5 ± 3.1 dias. Os sinais e sintomas observados foram febre, hidrofobia, aerofobia, agitação, desorientação, dispnéia, sialorréia, vômitos, oligúria, faringite, dor e hipoestesia no local da mordida, cefaléia, síncope, tosse, hematêmese, midríase, hematúria, constipação, dor cervical e priapismo. Em três de seis pacientes (50% foi encontrada evidência de insuficiência renal aguda, definida como creatinina > 1.4 mg/dL. Os achados de autópsia do tecido renal foram congestão glomerular leve a moderada e congestão capilar peritubular leve a intensa. Necrose tubular aguda foi encontrada em dois casos. Estes achados são inespecíficos, de modo que a instabilidade hemodinâmica, causada por disfunção autonômica, hidrofobia e desidratação podem ser considerados como responsáveis pela insuficiência renal aguda na raiva.

Objective: To determine in fatal cases of HCPS, clinical and morphological characteristics. Materials and Methods: Descriptive-retrospective analysis of seven fatal cases with postmortem study of HCPS, attended between 1997 and 2009 at the Hospital of Temuco, Chile. Results: Cases were young patients from rural areas, and presented as an illness of progressive respiratory failure, with leukocytosis, thrombocytopenia and bilateral interstitial pulmonary infiltrates. Main morphological findings were marked intersticial and intraalveolar pulmonary edema, with minimal epithelial injury and mononuclear cell intersticial infiltrate and mild edematous intersticial inflamatory process. Conclusions: Epidemiological, clinical and laboratory background allow to suspect HCPS. In fatal cases, the autopsy makes possible to discard other similar pathologies and provide tissue for confirmation of the disease.

    Full Text Available Analisam-se 51 casos de suicídio de idosos em dez municípios brasileiros, visando a conhecer a interação de variáveis associadas ao fenômeno. Uma revisão sobre o tema dá suporte teórico ao estudo. Tendo como base o método da autópsia psicológica, o estudo parte de um roteiro de entrevista semiestruturada, aplicada e analisada por pares de pesquisadores, mediante um mesmo procedimento de coleta, organização e análise dos dados. O conjunto foi reexaminado através de uma meta-análise de enfoque psicossocial e qualitativo sobre dados dos familiares entrevistados, interpretações dos pesquisadores, contextualização socioantropológica e categorias de relevância. Foram estudadas formas de perpetração e letalidade por sexo, faixa etária, perfil socioeconômico; fatores associados; e motivos atribuídos. Analisou-se a interação de fatores precipitantes relevantes. As conclusões apontam convergências entre estudos epidemiológicos e qualitativos. Doenças graves, deficiências e transtornos mentais juntos formam as principais causas, seguidas de depressão, conflitos familiares e conjugais. Recomenda-se atenção à qualidade de vida dos idosos, especialmente dos homens, que constituem o grupo de maior risco para suicídio.The authors analyze 51 cases of suicide among the elderly from ten Brazilian municipalities. The objective is to understand the interaction of variables associated with suicide among the elderly. A bibliographic review gives theoretical support to this study. Based on psychological autopsy, the study begins with a semi-structured interview format, which was applied and analyzed by peer researchers, using the same procedure for gathering, organizing and analyzing the data. This material was reviewed using a psychosocial and qualitative meta-analysis approach based on family interview data, researchers' interpretations, socio-anthropological contextualization and relevance categories. Ways of committing suicide, reasons for suicide, associated factors, attributed motives and lethality were studied by sex, age and socioeconomic characteristics. The interaction of major precipitant factors was analyzed. The conclusions showed that there are convergences among epidemiological and qualitative studies. Severe illness, disabilities and mental disorders are the major causes, followed by depression and family and marital conflicts. Close attention to the quality of life of the elderly is recommended, especially of men who constitute the main suicide risk group.

  6. An autopsy case of complete adipocere formation.

    Kasuda, Shogo; Kudo, Risa; Yuui, Katsuya; Imai, Hiroko; Nakata, Masatoshi; Hatake, Katsuhiko

    2016-01-01

    A car containing a male corpse with complete adipocere formation was found at the bottom of a lake. The deceased had presumably driven into the lake 7years earlier. The surface of the deceased was unusually hard and firm like a gypsum board, and the entire internal viscera had turned into adipocere. Since the time required for adipocerous changes depends largely on environmental conditions, we considered the key conditions, namely, water temperature, pH, and oxygen content. In our case, cold, acidic water may have delayed adipocere formation, thus necessitating a long period of time for completeness. On the other hand, anoxic conditions and the peculiar environment of a lake bottom presumably contributed to complete adipocere formation. PMID:26832376

    Full Text Available Una de las tareas más difíciles en patología forense puede ser determinar, después de la autopsia, el origen y la causa de la muerte cuando dichos extremos no están claros o son discutibles. Una autopsia técnicamente perfecta es condición necesaria pero no suficiente para cumplir adecuadamente esta decisión. En el presente trabajo se delimitan claramente los conceptos de causa y mecanismo de muerte, muerte natural y muerte violenta. Se revisan muchos de los aspectos relacionados con el diagnóstico del origen y la causa de la muerte; especialmente el enfoque actual del valor de la autopsia en el diagnóstico, la interacción entre traumatismo y enfermedad, la doctrina de la causalidad, la utilización de la CIE-10, la llamada etiología médico-legal, la autopsia psicológica, la "autopsia blanca" o negativa y el origen de la muerte por complicaciones de la terapéutica, etc., todos ellos se ilustran con ejemplos de casos representativos. Se discute el limitado papel del patólogo forense en España en la determinación de la denominada etiología médico-legal. Las conclusiones constituyen un conjunto de recomendaciones para el mejor cumplimiento de este trabajo, entre ellas el abandono de las denominadas causas de muerte inaceptables como parada cardiaca, parada cardiorrespiratoria o muerte cerebral, etc., la utilización siempre que sea posible de los diagnósticos de la CIE-10 y del formato del apartado de la causa de la muerte (parte I y II del modelo internacional de certificado médico de causa de defunción de la OMS. Todo ello como guía breve que facilite un resultado judicial adecuado y aumente la credibilidad del patólogo forense.One of the most difficult tasks in forensic pathology is deciding the origin and the cause of death after the autopsy when those issues are unclear or debatable. A technically perfect autopsy is a necessary but not a sufficient condition to adequately fulfil this decision. The present paper clearly defines the concepts of cause and mechanism of death, natural and violent death.

    Full Text Available Una de las tareas más difíciles en patología forense puede ser determinar, después de la autopsia, el origen y la causa de la muerte cuando dichos extremos no están claros o son discutibles. Una autopsia técnicamente perfecta es condición necesaria pero no suficiente para cumplir adecuadamente esta decisión. En el presente trabajo se delimitan claramente los conceptos de causa y mecanismo de muerte, muerte natural y muerte violenta. Se revisan muchos de los aspectos relacionados con el diagnóstico del origen y la causa de la muerte; especialmente el enfoque actual del valor de la autopsia en el diagnóstico, la interacción entre traumatismo y enfermedad, la doctrina de la causalidad, la utilización de la CIE-10, la llamada etiología médico-legal, la autopsia psicológica, la "autopsia blanca" o negativa y el origen de la muerte por complicaciones de la terapéutica, etc., todos ellos se ilustran con ejemplos de casos representativos. Se discute el limitado papel del patólogo forense en España en la determinación de la denominada etiología médico-legal. Las conclusiones constituyen un conjunto de recomendaciones para el mejor cumplimiento de este trabajo, entre ellas el abandono de las denominadas causas de muerte inaceptables como parada cardiaca, parada cardiorrespiratoria o muerte cerebral, etc., la utilización siempre que sea posible de los diagnósticos de la CIE-10 y del formato del apartado de la causa de la muerte (parte I y II del modelo internacional de certificado médico de causa de defunción de la OMS. Todo ello como guía breve que facilite un resultado judicial adecuado y aumente la credibilidad del patólogo forense.One of the most difficult tasks in forensic pathology is deciding the origin and the cause of death after the autopsy when those issues are unclear or debatable.

    Full Text Available Resumen Objetivo: Determinar si tipos específicos de eventos vitales constituyen de manera independiente factores de riesgo para el suicidio en Medellín, Colombia. Método: Estudio de casos y controles donde se tomaron 108 sujetos que fallecieron por suicidio (casos y 108 que habían muerto por otras causas (controles. Se equiparó por edad y sexo. Tanto en casos como en controles se aplicó la autopsia psicológica y se recolectó información sobre eventos vitales adversos en los seis meses previos a la muerte. Resultados: Al ajustar por la presencia de trastornos psiquiátricos, intentos previos de suicidio y antecedentes familiares de suicidio en el análisis de regresión logística condicional, los eventos que mostraron ser factores que aumentan el riesgo de suicidio fueron: ruptura con la pareja afectiva, desempleo, y con un alto OR, pero sin ser estadísticamente significativo, dificultades económicas. Dada la imprecisión de los resultados, un análisis no condicional mostró que los eventos adversos asociados de manera independiente con suicidio fueron: ruptura con la pareja afectiva y dificultades económicas. Conclusiones: Los eventos vitales adversos ruptura con la pareja afectiva, difi- cultades económicas y desempleo aumentan el riesgo de suicidio, independientemente de la presencia de otros factores. Dichos eventos deben tenerse en cuenta tanto en el diseño de estrategias de prevención y en las políticas de salud mental.Objective: To determine whether specific types of adverse life events are risk factors for suicide in Medellin, Colombia. Method: This is a case-control study conducted among 108 individuals who committed suicide (cases and 108 deceased from other causes (controls matched by age and gender. Both cases and controls were examined through psychological autopsy and information about adverse life events during the previous six months was collected. Results: After adjusting for psychiatric disorders, previous suicide attempts and family history of suicide using a conditional logistic regression analysis, partnership dissolution, and unemployment were found to be risk factors for suicide. Additionally, financial difficulties showed a high OR although it was not statistically significant. Since results lacked precision, we fitted a non-conditional model which pointed to the following events as independent risk factors for suicide: partnership dissolution and separation, and financial difficulties. Conclusions: Partnership dissolution, unemployment, and financial difficulties increase risk of suicide, regardless of other factors. These adverse life events must be taken into account for the design of prevention strategies and mental health policies.

  10. Guías para la práctica de la autopsia en casos de muerte súbita cardíaca Guidelines for autopsy investigation of sudden cardiac death

    Full Text Available A pesar de que la muerte súbita cardíaca es una de las formas más importantes de muerte en los países occidentales, este problema no ha recibido la atención que merece por parte de los patólogos y de los médicos de los sistemas públicos de salud. Se han desarrollado nuevos métodos de prevención de arritmias potencialmente mortales, y el diagnóstico de certeza de las causas de muerte súbita cardíaca es en este momento de particular importancia. Los patólogos son responsables de determinar la causa exacta de la muerte súbita pero existen diferencias considerables en el modo en el que se aborda esta cada vez más compleja tarea. La Asociación Europea de Patología Cardiovascular desarrolló unas guías que representan el estándar mínimo necesario en la práctica habitual de la autopsia para la valoración de la muerte súbita cardíaca, incluyendo no sólo un protocolo para el examen del corazón y el muestreo histopatológico, sino también para la investigación toxicológica y molecular. Nuestras recomendaciones son aplicables a centros médicos universitarios, a hospitales regionales y locales y a todo tipo de Institutos de Medicina Forense. La adopción a lo largo de la Unión Europea de un método uniforme de investigación supondrá la mejora de la práctica habitual, permitirá realizar comparaciones significativas entre distintas comunidades y regiones y, lo que es más importante aún, favorecerá que se monitoricen los patrones de las enfermedades que causan una muerte súbita.Although sudden cardiac death is one of the most important mode of death in Western Countries, pathologists and public health physicians have not given this problem the attention it deserves. New methods of preventing potentially fatal arrhythmias have been developed, and the accurate diagnosis of the causes of sudden cardiac death is now of particular importance. Pathologists are responsible for determining the precise cause of sudden death but there is considerable variation in the way in which they approach this increasingly complex task. The Association for European Cardiovascular Pathology developed guidelines, which represent the minimum standard that is required in the routine autopsy practice for the adequate assessment of sudden cardiac death, including not only a protocol for heart examination and histological sampling, but also for toxicology and molecular investigation. Our recommendations apply to university medical centres, regional and district hospitals and all types of forensic medicine institutes. If a uniform method of investigation is adopted throughout the European Union, this will lead to improvements in standards of practice, allow meaningful comparisons between different communities and regions and, most importantly, permit future trends in the patterns of disease causing sudden death to be monitored.

    Full Text Available El registro de los nacimientos, el registro de las defunciones por edad, sexo y causas y el cálculo de los niveles y diferenciales de mortalidad son fundamentales para articular políticas sanitarias basadas en la evidencia y para llevar a cabo el seguimiento y evaluación. No obstante, pocos de los p [...] aíses que más necesidad tienen de esos datos disponen de sistemas operativos para producirlos, aunque la legislación prevea el establecimiento y mantenimiento de sistemas de registro civil. Los sistemas de registro de estadísticas vitales por muestreo (REVM), si se combinan con procedimientos de autopsia verbal validados y aplicados en una muestra de conglomerados de población nacionalmente representativa, representan una solución asequible, costoeficaz y sostenible a corto y medio plazo para ese problema. Los REVM complementan otras fuentes de información generando datos de mortalidad por edad, sexo y causas que son más completos y continuos que los datos actualmente disponibles. Los instrumentos y métodos empleados en los sistemas REVM, sin embargo, son imperfectos y exigen mecanismos rigurosos de validación y una continua garantía de la calidad; también se están perfeccionando todavía las estrategias de muestreo para los REVM. Así y todo, el interés por establecer REVM está aumentando rápidamente enÁfrica y Asia. Unos sistemas mejorados de notificación y registro de los datos sobre acontecimientos vitales sólo serán sostenibles si se desarrollan en estrecha conexión con las estrategias de información sanitaria aplicadas en los niveles nacional y distrital, las estructuras de gobernanza, y las agendas de las investigaciones sociales y la vigilancia del desarrollo. Si la comunidad mundial desea disponer de mediciones de la mortalidad dentro de 5 o 10 años, hay que sentar ya las bases de los sistemas REVM. Abstract in english Registration of births, recording deaths by age, sex and cause, and calculating mortality levels and differentials are fundamental to evidence-based health policy, monitoring and evaluation. Yet few of the countries with the greatest need for these data have functioning systems to produce them despi [...] te legislation providing for the establishment and maintenance of vital registration. Sample vital registration (SVR), when applied in conjunction with validated verbal autopsy procedures and implemented in a nationally representative sample of population clusters represents an affordable, cost-effective, and sustainable short- and medium-term solution to this problem. SVR complements other information sources by producing age-, sex-, and cause-specific mortality data that are more complete and continuous than those currently available. The tools and methods employed in an SVR system, however, are imperfect and require rigorous validation and continuous quality assurance; sampling strategies for SVR are also still evolving. Nonetheless, interest in establishing SVR is rapidly growing in Africa and Asia. Better systems for reporting and recording data on vital events will be sustainable only if developed hand-in-hand with existing health information strategies at the national and district levels; governance structures; and agendas for social research and development monitoring. If the global community wishes to have mortality measurements 5 or 10 years hence, the foundation stones of SVR must be laid today.

    Full Text Available O presente estudo tem como objetivo a apresentação dos achados de cisticercose nas necrópsias realizadas no Serviço de Patologia do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto-USP, no período de 1992 a 1997. Das 2522 necrópsias, a neurocisticercose foi detectada em 38 (1,5% dos casos. Destes, 22 (57,9% foram diagnosticados apenas na necrópsia enquanto 16 (42,1% apresentavam exames complementares consistentes com cisticercose. A análise dos prontuários médicos evidenciou que 21 (55,2% eram neurologicamente assintomáticos e a frequência das diversas manifestações clínicas estava de acordo com os dados da literatura. A elevada frequência de indivíduos assintomáticos detectados apenas através da necrópsia demonstra a importância desta como fonte complementar de dados para a consolidação da notificação compulsória da cisticercose. Embasado nos dados do presente estudo, o atual coeficiente de prevalência da cisticercose no município de Ribeirão Preto é 67 casos/100000 habitantes.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/100000 inhabitants.

É importante reverter esta tendência por medidas que valorizam a realização e a otimização das autópsias. Objetivos: Comparar prospectivamente os achados macro e microscópicos de 200 autópsias, visando analisar o impacto e a relação custo/benefício do estudo histopatológico de todos os órgãos sobre os diagnósticos provisórios macroscópicos e sobre os laudos finais de encerramento. Metodologia: Analisamos 200 autópsias consecutivas realizadas no Departamento de Patologia da Escola Paulista de Medicina/Unifesp, e avaliamos a concordância e a discordância entre os diagnósticos macroscópicos provisórios e os microscópicos finais. Resultados: Houve concordância entre os diagnósticos macro e microscópicos em 143 casos (71,5% e discordâncias em 22 casos (11%, classificadas como leves em 14 casos (7% e graves em oito casos (4%. Em 35 casos (17,5%, a histopatologia revelou alterações sem expressão macroscópica e cujo diagnóstico final foi histológico. Conclusão: O elevado índice de concordância detectado entre os diagnósticos macro e microscópicos, sendo a maioria das discordâncias classificada como leve, parece indicar que as autópsias podem ser encerradas com estudo histopatológico limitado às alterações macroscópicas mais evidentes, com significativa redução de custo (cerca de R$ 300,00 por autópsia e grande melhoria no retorno, em curto período de tempo, da informação para o corpo clínico da instituição.Background: Despite the development in diagnostic medicine, discrepancy between clinical diagnoses and the ones obtained by autopsy has remained around 10-20%. It is important to revert this tendency by measures that value the realization and optimization of autopsies. Objectives: Prospectively compare gross and microscopic findings of 200 autopsies, viewing to analyze the impact and the cost/benefit value of the histopathological study of all organs over provisory microscopic diagnoses and over enclosure final awards. Methods: We analyzed 200 consecutive autopsies performed at Departamento de Patologia da Escola Paulista de Medicina/Unifesp and evaluated agreement and disagreement between provisory gross diagnoses and final microscopic ones. Results: There was agreement between gross and microscopic findings in 143 cases (71.5% and disagreement in 22 cases (11%, classified as light in 14 cases (7% and serious in eight cases (4%. In 35 cases (17.5%, histopathological study revealed alterations with no gross significance which had final histological diagnosis. Conclusion: The high agreement index detected between gross and microscopic findings, most discrepancies being classified as light, seems to indicate that autopsies may be closed with histopathological study limited to the most evident gross alterations, with significant cost reduction (around R$ 300 per autopsy and great improvement in the return, in a short period of time, of information to the institution clinical staff.

MÉTODOS: Avaliaram-se todos os pacientes que morreram na unidade de terapia intensiva do Hospital Universitário da Universidade Federal de Juiz de Fora entre 1995 e 2003 e que foram submetidos à necropsia. Seus prontuários foram revisados para estabelecer a presença ou não dos critérios clínicos de SDRA, cujo diagnóstico histológico foi definido pela presença de dano alveolar difuso (DAD. RESULTADOS: No período, 592 pacientes faleceram e 22 foram submetidos à necropsia. Destes, 10 pacientes (45% preencheram os critérios de SDRA pela AECC e sete (32% preencheram os critérios histopatológicos de DAD.

CONCLUSÃO: A precisão dos critérios da AECC para diagnóstico de SDRA não é tão boa. Em função do baixo valor preditivo positivo e da baixa razão de verossimilhança positiva do diagnóstico clínico, outras hipóteses devem ser consideradas quando há suspeita de SDRA.OBJECTIVE: To compare the American-European Consensus Conference (AECC definition of acute respiratory distress syndrome (ARDS to autopsy findings. METHODS: All patients who died in the intensive care unit of the Federal University of Juiz de Fora University Hospital between 1995 and 2003 and were submitted to autopsy were included in the study. Patient clinical charts were reviewed to establish whether cases met the AECC criteria for a diagnosis of ARDS, histologically defined as the presence of diffuse alveolar damage (DAD. RESULTS: During the study period, 592 patients died, and 22 were submitted to autopsy. Of those 22 patients, 10 (45% met the AECC criteria, and 7 (32% met the histopathological criteria for DAD. The AECC clinical criteria presented a sensitivity of 71% (95%CI: 36-92% and a specificity of 67% (95%CI: 42-85%. The positive and negative predictive values were, respectively, 50 and 83%, whereas the positive and negative likelihood ratios were, respectively, 2.33 and 0.47. The histopathological findings in the 5 patients who met AECC criteria but did not present DAD were pneumonia (n = 2, pulmonary embolism (n = 1, tuberculosis (n = 1, and cryptococcosis (n = 1. CONCLUSION: The accuracy of the AECC definition of ARDS was godless than satisfactory. Due to the low positive predictive value and the low positive likelihood ratio, other hypotheses must be considered when ARDS is suspected.

    Full Text Available El daño múltiple de órganos es un conjunto de trastornos morfológicos frecuentes en pacientes críticos, asociado con diversos factores causales donde primordialmente ocurre un daño inmunológico que se concatena con un daño sistémico, y que de acuerdo con su intensidad puede evolucionar hacia la muerte inmediata, regresar o manifestarse evolutivamente con un síndrome de daño múltiple de órganos. Se realizó este trabajo con el propósito de identificar el comportamiento y la relación de los factores causales del daño múltiple de órganos en las autopsias de adultos del Instituto Superior de Medicina Militar "Dr. Luis Díaz Soto". Se estudiaron retrospectivamente 13 910 fallecidos entre el año 1962 y 2004, de ellos 11 307 mayores de 16 años de edad según la base de datos SARCAP, divididos en grupos de estudios en relación con los factores causales. Para el diagnóstico se consideró la presencia del factor causal, 3 o más órganos afectados; se excluyeron estos cuando presentaban lesiones previas relacionadas con el daño múltiple de órganos, y se valoró la sepsis, solo la severa. El trabajo muestra cómo el daño múltiple de órganos se relaciona con los factores causales que lo desencadenan y se analiza que evitar la acción de los factores causales contribuiría a prolongar la vida de los pacientes si se aplican medidas terapéuticas que atenúen la respuesta inflamatoria sistémica y el daño múltiple de órganos, por lo que su prevención salva vidas.The multiple organ damage is a set of frequent morphological disorders in critical patients, associated with causal factors, where it mainly occurs an immunological damage that concatenates with a systemic damage and that according to its intensity it may evolve towards immediate death, recurs or manifest with a syndrome of multiple organ damage. This paper was aimed at identifying the behavior and the relation of the causal factors of the multiple organ damage in the autopsies of adults performed in "Dr. Luis Díaz Soto" Higher Institute of Military Medicine. 13 910 deceased were retrospectively studied between 1962 and 2004, of them 11 307 were over 16 according to the SARCAP database. They were divided into study groups according to the causal factors. For the diagnosis, it was considered the presence of causal factors, 3 or more affected organs that were excluded when they presented previous lesions related to multiple organ damage, and only severe sepsis was assessed. It was proved how the multiple organ damage was related to the causal factors triggering them, and it was also concluded that avoiding the action of the causal factors would contribute to prolong the patients' life if therapeutical measures attenuating the systemic inflammatory response and the multiple organ damage were taken, since their prevention may save lives.

  1. ["Violence and health": an autopsy of a public health plan].

    Gignon, Maxime; Jarde, Olivier; Manaoul, Cécile

    2010-01-01

    The law provides for an evaluation and a five-year review of the French Public Health Act. Among its five strategic plans, the law of August 9, 2004 provided for a "national plan to limit the health impact of violence, risk behavior and addictive behavior." Under the impetus of the World Health Organization's World Report on Violence and Health in 2000, a rich reflection was conducted in France on this issue establishing some key axes for implementation. Although we can link several actions related to this field within the framework of specific policies since 2004 (road violence, addictions, violence against women, etc.), we note that a plan on violence and health has not emerged. The lack of enforcement and application of this part of the law raises questions about the quality of the law as well as the in the role and place for the theme "violence and health" in an upcoming law.

    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.

  5. Problem in twin pregnancy: Findings of prenatal sonography and autopsy

    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.

    2012-06-01

    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.

    Any crime scene investigation is a real challenge for those involved in forensic examination. Especially in those cases where a death ocurred, evidence dynamics and the amount of data colected must lead to an undoubtful conclusion. In some cases investigators have to establish a clear difference between accident, suicide, homicide, and a natural death. It is the case of equivocal death, where is necessary to understand all the psychosocial factors who have contributed to this end in order to ...

  10. Social Resilience in Online Communities: The Autopsy of Friendster

    Garcia, David; Schweitzer, Frank

    2013-01-01

    We empirically analyze five online communities: Friendster, Livejournal, Facebook, Orkut, Myspace, to identify causes for the decline of social networks. We define social resilience as the ability of a community to withstand changes. We do not argue about the cause of such changes, but concentrate on their impact. Changes may cause users to leave, which may trigger further leaves of others who lost connection to their friends. This may lead to cascades of users leaving. A social network is said to be resilient if the size of such cascades can be limited. To quantify resilience, we use the k-core analysis, to identify subsets of the network in which all users have at least k friends. These connections generate benefits (b) for each user, which have to outweigh the costs (c) of being a member of the network. If this difference is not positive, users leave. After all cascades, the remaining network is the k-core of the original network determined by the cost-to-benefit c/b ratio. By analysing the cumulative dist...

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

    Svetlana V. Konstantinova-Larsen

    2011-12-01

    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.

    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 executado quando outros procedimentos não forneceram um diagnóstico urgente e específico; no entanto, pode haver relutância em sua execução em pacientes críticos, que apresentam infiltrados pulmonares difusos. OBJETIVO: Avaliar a acurácia diagnóstica, mudanças na terapêutica e a sobrevida de pacientes com infiltrado pulmonar difuso, em sua maior parte apresentando a insuficiência respiratória aguda, submetidos a biópsia cirúrgica. MÉTODO: Foram examinados retrospectivamente registros médicos e biópsias pulmonares cirúrgicas de 63 pacientes maiores de 18 anos de idade, com infiltrados difusos, entre 1982 a 2003. Os diagnósticos clínicos foram comparados aos histopatológicos, de biópsias e de autópsias. Dados laboratoriais e epidemiológicos foram avaliados e sua correlação com a sobrevida hospitalar analisada. RESULTADOS: Todos os espécimes histológicos exibiram alterações, em sua maior parte de natureza benigna/inflamatória. Em quinze casos o fator etiológico pôde ser determinado na biópsia, sendo o Mycobacterium tuberculosis o mais freqüente. O diagnóstico pré-operatório foi mudado em 37 pacientes. Autópsias foram realizadas em 25 pacientes e confirmaram resultados da biópsia em 72%. A terapêutica foi alterada em 65% dos pacientes com base nos resultados da biópsia. Quarenta e nove por cento dos pacientes sobreviveram ao final do período de hospitalização. Características que diferiram significativamente entre sobreviventes versus não sobreviventes incluíram sexo (p=0.05, a presença de comorbidade (p=0.05, a SatO2 (p=0.05, e a presença de dano alveolar difuso na biópsia (p=0.004. CONCLUSÃO: A biópsia pulmonar cirúrgica forneceu um diagnóstico etiológico específico e exato em muitos pacientes com infiltrados pulmonares difusos quando a melhora clínica não ocorreu após o tratamento padrão. A biópsia pulmonar cirúrgica pode fornecer diagnósticos que requerem tratamentos específicos, com provável impacto na redução do índice de mortalidade destes pacientes.

    Full Text Available PURPOSE: The purpose of this study was to identify the possible alteration in the thickness of the epithelium basal membrane of the vocal cords and correlate it with the cause of death. METHOD: Larynxes collected from adult autopsies during the period of 1993 to 2001 were utilized. We used the hematoxylin-eosin and periodic acid-Schiff staining methods for the morphological and morphometric analysis. RESULTS: Sixty-six vocal cords were analysed; increased thickness was identified in 14 cases (21.2%, with equal proportions between the genders. Increased vocal-cord thickness was more frequent in patients of the white ethnicity (12 cases, 85.7%. Respiratory alterations were found in 10 (71.4% of the cases with increased vocal-cord thickness. Of the patients that were maintained with mechanical ventilation before death, 7 (18.4% had thickening of the basal membrane. Among the smokers, 9 (19.63% had basal membrane thickening. CONCLUSION: No statistically significant differences were found between the cases in which the cause of death was related to respiratory diseases as compared to non-respiratory diseases and the thickening of the basal membrane of the vocal cords. However, new studies are needed in order to verify the etiopathogenesis of this thickening.OBJETIVO: O objetivo deste trabalho foi identificar as possíveis alterações na espessura da membrana basal das cordas vocais e relacionar estas com a causa de morte. MÉTODO: Foram utilizadas laringes coletadas de adultos autopsiados, no período de 1993 até 2001. Realizamos as colorações da Hematoxilina- Eosina e Ácido Periódico de Schiff, onde foi medido o diâmetro da membrana basal. RESULTADOS: Foram analisadas 66 cordas vocais, o espessamento foi identificado em 14 casos (21,2%, sendo encontrado em proporções iguais entre os sexos, sendo freqüente em pacientes da cor branca (12 casos, 85,7%. Foram encontradas alterações respiratórias em 10 (71,4% dos casos com espessamento. Entre os pacientes intubados, 7 (18,4% apresentaram espessamento. Entre os fumantes 9 (19,63% apresentavam espessamento. Não houve influência estatisticamente significativa do espessamento na doença que levou o indivíduo à morte. CONCLUSÃO: Em relação a causa de morte não há diferença estatisticamente significante entre os casos cuja causa de morte foi por doenças respiratórias ou por doenças não respiratórias e o diagnóstico de espessamento da membrana basal das cordas vocais. Sua etiopatogênese necessita de maiores estudos.

A pesar de la aplicación de maniobras de resucitación el sujeto presentó parada cardiorrespiratoria y exitus. Durante la autopsia Médico- Legal se demostró la existencia de una tumoración mesentérica, localizada en el ileon distal. El cadáver despedía un olor "sui generis" que le recordó al Médico Forense el típico de algunos plaguicidas organofosforados. Se avanzaron los siguientes diagnósticos de la causa de la muerte en el informe de autopsia: 1 Shock séptico por absceso intestinal. 2 Intoxicación mortal por plaguicidas. 3 Muerte súbita cardiaca. La investigación químico-toxicológica resultó negativa. El estudio anatomopatológico no demostró lesiones cardiacas que pudiesen justificar la muerte y, el de la tumoración mesentérica demostró que se trataba de una duplicación intestinal, de tipo quístico, con discreta inflamación crónica de la pared; no se pusieron de manifiesto ulceraciones, hemorragias ni lesiones vasculares o isquémicas intestinales que pudiesen justificar una muerte súbita de causa digestiva. La causa y la manera de la muerte se consideraron de tipo indeterminado.We present a case of sudden and unexpected death in a 19 year-old, who in the hours prior to his death presented a clinical picture of dizziness, nausea and vomiting which was treated at the First-Aid Centre with analgesics and antispasmodics. After a few hours the patient was again taken to the Medical Centre by his relatives, by then unconscious. In spite of resuscitation measures the patient presented cardio-respiratory arrest and death. During the forensic autopsy the existence of a mesenteric tumour was discovered in the distal ileum. The corpse gave off a peculiar smell which reminded the pathologist of the typical smell of some organophosphorous pesticides. The following diagnoses for the cause of death were put forward in the pathologists report: 1 Septic shock due to intestinal abscess. 2 Mortal poisoning by pesticides. 3 Sudden cardiac death. The chemical-toxicological investigation resulted negative. The histopathologic study did not show cardiac lesions which could justify the death, and the study of the mesenteric tumour showed that it was a cystic intestinal duplication, with discreet chronic inflammation of the wall; ulcerations, haemorrhage, vascular or ischaemic intestinal lesions which could have justified sudden death with digestive causes, were not seen. The cause and manner of death were considered undetermined.

    Full Text Available OBJETIVO: Determinar o peso dos ventrículos cardíacos em necropsia de indivíduos sadios vítimas de morte acidental, visando determinar padrões de normalidade em nossa população. MÉTODOS: Foram examinados 94 corações no Instituto Médico Legal de Vitória. Após remoção do coração e ressecção dos átrios e gordura epicárdica, os ventrículos direito (VD e esquerdo (VE, incluindo o septo, foram separados e pesados e a massa indexada pela altura. O teste de Kolmogorov-Smirnov foi usado para testar normalidade da distribuição. Os dados são apresentados como média ± desvio padrão. RESULTADOS: Após 12 exclusões (doença cardiovascular possível detectada após a morte foram analisados 82 corações (52 homens e 30 mulheres, 16-68 anos, média 31±12 anos. O peso do VE foi de 181±25 g e 125±15 g, do VD foi de 54±7 g e 38±6 g e a massa de VE indexada pela altura foi de 105±14 g/m e 78±8 g/m para homens e mulheres, respectivamente. O P95 do peso do VE foi de 218 g e 128 g/m em homens e 148 g e 88 g/m em mulheres. Não detectamos correlação significante entre a massa ventricular e idade. CONCLUSÃO: O peso do ventrículo esquerdo do coração dos homens da nossa amostra foi superior aos relatados na literatura contemporânea. Nossos resultados sugerem que a presença de hipertrofia de VE pode ser inferida em presença de massa de VE superior a 218 g ou 128 g/m nos homens e 148 g ou 88 g/m nas mulheres.OBJECTIVE:To establish cardiac ventricular weights recorded during the autopsy of healthy individuals who died of external causes, aiming at determining normality patterns in our population. METHODS:A total of 94 hearts were evaluated at the Forensics Department of the city of Vitória, Espírito Santo. After the heart removal and resection of the atria and epicardial fat, the right ventricle (RV and the left ventricle (LV, including the septum, were separated and weighed and the mass was indexed by the height. The Kolmogorov-Smirnov test was used to test the normality of the distribution. Data are presented as means± SD. RESULTS:After the exclusion of 12 hearts (possible cardiovascular disease detected post-mortem 82 hearts were examined (52 males and 30 females, aged 16-68 yrs, 31±12 yrs. The weight of the LV was 181±25 g and 125±15 g, and the weight of the RV was 54±7 g and 38±6 g; the LV mass indexed by height was 105±14 g/m and 78±8 g/m, for males and females, respectively. The P95 of the LV weight was 218 g and 128 g/m in males and 148 g and 88 g/m in females. No significant correlation between ventricular mass and age was observed. CONCLUSION:The weight of the LV in the males from our sample was higher than that reported in the contemporary literature. Our results suggest that the presence of LV hypertrophy can be inferred in the presence of LV mass > 218 g or 128 g/m in males and 148 g or 88 g/m in females.

    Full Text Available TITLE: Ultrasound guided fine needle aspiration cytology (FNAC in diagnosis of space occupying lesions (SOL of liver. INTRODUCTION: Liver is an important organ for metabolism of body and is also a drainage site for many organs, therefore it becomes affected in many benign, malignant and inflammatory conditions and performing ultrasound guided FNA helps to diagnose cases with 90-95% accuracy and minimizing the requirement of biopsy. AIMS: To evaluate the efficacy of ultrasound guided FNA and to look for spectrum of diseases affecting liver. MATERIAL AND METHODS: The study is performed on patients who came with lump abdomen and had SOL in liver on ultrasonography in SMS hospital, Jaipur. Ultrasonography guided FNAC was performed on 360 patients in one year period from January 2013 to December 2013. Majority of the patients were males and most of them were middle to elderly age group. Samples were adequate in 324 (90% and inadequate in 36 (10%. Out of 360 patients 7 had benign lesions, rest all had malignant tumors. Of all the malignant tumors, metastatic tumors were commonest accounting for 68% cases, hepatocellular carcinoma accounted for 15% and the rest 17% were unclassified malignancies. CONCLUSION: Ultrasonography guided FNAC is a simple, safe, cost effective and accurate diagnostic method for cytological diagnosis of hepatic lesions. It can be practiced in any centre where ultrasound facility and specialist pathologists are available. Cell blocks can be prepared from FNAC material which is of great help especially in cases who have unknown primaries and present with metastasis in liver

  4. Oil spill, impact of a disaster; Maree noire, autopsie d'une catastrophe

    Crie-Wiesner, H.

    2010-09-15

    The main figures of the recent Deepwater oil spill in the gulf of Mexico are: -) the volume of spilled oil is 780 million liters, -) the volume of oil-water mix that has been recovered so far is 130 million liters, -) a sea area of 15 million hectares has been prohibited for fishing, and -) a 1320 km length of floating barrier has been settled. University laboratories have received funds from NOAA (National Oceanic and Atmospheric Administration), NSF (National Science Foundation) and BP to investigate the impact on the environment. Usually dispersants are spread on the surface of the spill to break oil but for the Deepwater disaster the dispersants have been injected directly at the level of the leak at a 1500 m water depth. It seems that the dispersants have acted efficiently but their impact on the environment is far from being assessed. Several catamarans equipped for recovering oil have been used. It is expected that the sediment layer will released oil into the sea for years. (A.C.)

    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.

    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, su...

  8. Heidenhain variant of Creutzfeldt-Jakob disease: An autopsy study from India

    2009-01-01

    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.

  9. A geostatistical autopsy of the Austrian indoor radon survey (1992-2002)

    Indoor radon (Rn) concentrations have been measured intensively in many countries to assess the burden of diseases associated with exposure to this radioactive gas. So-called radon-risk maps have consequently been produced to delineate areas with high levels. Geostatistical techniques are commonly used nowadays to map a range of environmental variables, in particular to generate probability maps of exceeding a given threshold. However, very few case studies in which indoor radon measurements have been investigated using geostatistical techniques have been published so far. By analyzing around 12,000 Rn measurements made in Austrian ground floors during a 10-year survey, we aim here to review and discuss the potential of geostatistics for mapping an environmental variable that shows very strong local variability. In particular, we show how kriging of the scale components can shed new light on various factors that affect the very high spatial variability of the variable

  10. Effects Of Continuous Argon Laser Irradiation On Canine And Autopsied Human Cardiac Tissue

    Ben-Shachar, Giora; Sivakoff, Mark; Bernard, Steven L.; Dahms, Beverly B.; Riemenschneider, Thomas A.

    1984-10-01

    In eight human formalin preserved cardiac specimens, various cardiac and vascular obstructions were relieved by argon laser irradiation. Interatrial communication was also produced by a transar'rial approach in a live dog. In-vivo fresh canine cardiac tissues required power density of at feast 80, 90, and 110 watts/cm2 for vaporization of myocardial, vascular and valvular tissues respectively. The fiber tip to tissue distance (effective irradiation distance) for effective vaporization was less than I mm for vascular and valvular tissues and less than 4 mm for myocardium. Light microscopy showed four zones of histological damage common to all tissues - central crater surrounded by layers of charring, vacuolization and coagulation necorsis. Myocardium showed additionally a layer of normal appearing muscle cells (skip area) surrounded by a peripheral coagulation halo. Laser irradiation effects on valvular tissue showed the most lateral extension of coagulation necrosis. It is concluded that palliation and treatment of certain congenital heart defects by laser irradiation is anatomi-cally feasible and may be safe for in vivo application when low power output and short exposure time are used from a very short irradiation distance.

    2016-03-30

    A 60-year-old man was admitted to our hospital because of vertigo and repeated vomiting, which suddenly occurred 25 hours before admission. Neurologic examination revealed Wallenberg syndrome on the left side, and brain MRI showed acute infarcts in the left lateral medulla as well as in the left internal carotid artery (ICA) territory. MR angiography did not depict the left vertebral artery (VA) and the left ICA. Despite antithrombotic treatment, he developed bulbar palsy, and then, brain herniation due to infarct growth in the left middle cerebral artery territory. He died on day 9. Histopathlogical examination found verruca involving the mitral leaflet, which was consistent with non-bacterial thrombotic endocarditis (NBTE). Atherosclerosis was also found in the systemic arteries, and there was sclerotic stenosis with calcification at the portion of piercing dulla matter in the left VA and at the cavernous segment of the left ICA. Because the cerebral emboli in the narrowed lumen presented a histologic appearance similar to that of the verruca, the diagnosis of brain embolism due to NBTE was confirmed. PMID:26960272

Se describe un caso de un feto muerto con hallazgos histopatológicos de un teratoma sacro coccígeo inmaduro.Pacientes y Métodos: Mujer de 26 años de edad en su cuarto embarazo de 32 semanas de gestación, quien presenta amenaza de parto pre término. Se le realiza una ecografía obstétrica que informa la presencia de una masa sacra fetal, e hidrops fetal. Se realizó cesárea y se obtiene un óbito fetal de sexo femenino. El estudio anatomopatológico evidenció un teratoma sacrococcígeo inmaduro. Conclusiones: En los teratomas sacrococcígeos fetales, el desarrollo de hidrops fetal, insuficiencia cardiaca y gran tamaño tumoral son indicadores de mal pronóstico. El diagnóstico prenatal, la planificación del parto, la estabilización perinatal y la resección quirúrgica del tumor, pueden hacer posible la sobre vida en estos pacientes.

We describe a case of a dead fetus with an immature sacrococcygeal teratoma, its radiological and histological findings. Patients and Methods: A 26 years old woman in the fourth pregnancy of 32 weeks' of gestation, who presented the threat of pre-term birth. We performed obstetric ultrasound reporting the presence of a fetal sacral mass and fetal hydrops. Caesarean section was run and got a female fetal death. Pathologic study showed immature sacrococcygeal teratoma. Conclusions: In fetal sacrococcygeal teratomas, the development of fetal hydrops, heart failure and large tumor size are indicators of poor prognosis. Prenatal diagnosis, planning delivery, the postnatal stabilization period and surgical resection of the tumor, can make survival possible in these patients. Salud UIS 2010; 42: 127-131.

    2012-08-01

    Herein we describe a patient with established corticobasal degeneration with onset of nonfluent aphasia and showing symmetrical cerebral involvement. A 64-year-old man with a speech disorder for 2 years visited our hospital. He had nonfluent aphasia (reduced spontaneous speech, loss of intonation, anomia, repetition disorder, and difficulty in speaking short sentences). He also showed right-sided motor neglect, hypertonus of the left lower limb, a mask-like facial expression, and difficulty in closing his eyes. He was restless and walked around even during examination, suggesting frontotemporal dementia (FTD). Single-photon emission computed tomography (SPECT) revealed symmetrical reduction of cerebral blood flow in the bilateral fronto-temporo-parietal lobes. His neurological condition deteriorated gradually and a year later he could not speak comprehensive sentences. Magnetic resonance imaging (MRI) of the head at age 70 showed symmetrical atrophy of the bilateral fronto-temporal lobes. He died of respiratory failure after clinical problems lasting ten years. On pathological examination, the fixed brain weighed 1,010 g and showed bilateral symmetrical atrophy of the frontal lobes. Histopathological examination revealed neuronal loss and gliosis in the frontal lobes, especially in the frontal convexity, superior frontal gyrus and precentral gyrus. Gallyas-Braak silver staining showed astrocytic plaques, argyrophilic threads and coiled bodies mainly in the frontal lobes. The substantia nigra showed severe neuronal loss on both sides and presence of free melanin. Pathological diagnosis was corticobasal degeneration (CBD). We believe that the patient had nonfluent aphasia and FTD reflected in bilateral degeneration of the frontal lobes. Some cases of CBD may present with symmetrical degeneration of the brain, even though left-hemisphere symptoms such as aphasia reveal themselves at an early stage. PMID:22868886

    Meunier, C; Dwarkadas, V V; Koribalski, B; Emonts, B; Hunstead, R W; Campbell-Wilson, D; Stockdale, C; Tingay, S J

    2013-01-01

    We present archival radio observations of SN1996cr from ATCA and MOST, and model its radio lightcurves using X-ray constrained hydrodynamical simulations of the interaction between the SN ejecta and the CSM. The early radio data show signs of free-free absorption (FFA), which decreases gradually and is minimal above 1.4 GHz after day ~3000. FFA optical depth constraints provide estimates of the CSM free electron density, which allows insight into the ionisation of SN1996cr's CSM and offers a test on the density distribution adopted by the hydrodynamical simulation. The intrinsic spectral index of the radiation shows evidence for spectral flattening, which is characterised by alpha = 0.852 +/- 0.002 at day 3000 and a decay rate of d_alpha = -0.014 +/- 0.001 yr^-1. The similarity in the spectral flattening of SN1987A, SN1993J, and SN1996cr suggests this may be a relatively common feature of SNe/CSM shocks. We adopt this spectral index variation to model the synchrotron radio emission of the shock, and consider ...

  1. The prevalence and abundance of internal parasites in working horses autopsied in Poland.

    Gawor, J J

    1995-05-01

    The digestive tracts of 50 working horses from private farms in Poland were examined. Thirty-seven nematode species, two tapeworm species and one species of botfly were recovered. The most prevalent small strongyle species were Cyathostomum catinatum, Cylicocyclus nassatus, Cylicostephanus goldi, Cylicostephanus longibursatus, Cyathostomum coronatum, Cylicostephanus calicatus, Cylicocyclus leptostomus and Cylicostephanus minutus. Thirteen cyathostome species showed a site preference in the ventral colon, five in the dorsal colon and three in the caecum. One species, Cylicocyclus triramosus, was new for Poland. Delafondia vulgaris was the most common large strongyle, with 74% prevalence, but low abundance. Parascaris equorum (26%) and Oxyuris equi (36%) were common. Strongyloides westeri (4%), Habronema majus (16%) and Habronema muscae (8%) were less prevalent. Both Habronema species were new for Poland. Tapeworm infection were not prevalent (Anoplocephala magna (4%) and Anoplocephala perfoliata (4%)). Botfly larvae were found in 40% of the horses examined. It was stated that no anthelmintics had been used on the farms. PMID:7676606

    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 examination results and information on caffeine concentrations in the blood, urine and main organs in a fatal caffeine intoxication case. Even though high caffeine concentrations were found in the systemic organs, no caffeine-related pathological changes were detected. PMID:26023259

    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...

    2014-01-01

    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). PMID:24033426

    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 posterio...

    Background Treatment of primary renal cell carcinoma using radiotherapy with curative intent is rare, because renal cell carcinoma is generally regarded as a radiation-resistant tumor. Recently, stereotactic body radiation therapy has been radically applied for cancers in various organs including renal cell carcinoma. However, there were few reports describing pathological changes of renal cell carcinoma post stereotactic body radiation therapy. This is the first report we are aware of docume...

    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. PMID:3269246

  12. An autopsy case of a charred body which committed suicide after arson.

    Tatsumi, S; Noda, H; Sugiyama, S

    2000-08-01

    A severely burned body was found lying on its right side at the scene of the fire in a 2-story wooden apartment house. The presence of a ligature (an electrical cord) running horizontally around the neck aroused suspicion of arson after homicidal strangulation (murder-arson). The entire body was severely burned and partly charred. The head and neck were severely charred, and the left temporal bone had been consumed exposing the brain. Around the neck was looped an electrical cord, which ran horizontally and canted downward toward the nape, leaving a furrow resulting from the knot being tightened up. No other injuries or pathologic lesions suggestive of the cause of death were noted. No drug, poison or alcohol was detectable in the blood or urine. The peculiar method of making a noose of the ligature around the neck is called clove hitch, which makes the noose tighten further with increased load. The fallen curtain rod had a bend with an acute angle, which was considered to have been the point of suspension in hanging. In addition, a lighter was found under the corpse, which was presumably used to ignite the gasoline that the deceased sprinkled. We speculate, therefore, that the deceased hanged himself by placing the electrical cord around his neck (by clove hitch), suspending it from the curtain rod, sprinkling gasoline in his room, igniting it with a lighter, executing suicidal hanging after the start of the fire. Probably the body was wrapped in flames while dangling, then fell to the floor together with the collapsing curtain rod. PMID:12935453

  13. On autopsy case in which leukemia occurred following irradiation after the operation of bilateral carcinoma

    A 53-year-old female. The carcinoma of the breast was found at the 50 years old. After bilateral mastectomy, Linac x-ray (300 rads/once) was irradiated with Mantle technique 20 times (total, 6000 rads) for 55 days. After irradiation, there was no edema or stagnation of lymph flow on both arms. The number of leucocytes were decreased from 8600 before irradiation to 4600 during irradiation, and it was 4700 9 months after the end of irradiation. Anemia was pointed out 2 years 7 months later. At that time, the number of erythrocytes was 3280000, hemoglobin 4.3 g/dl, and hematocrit was 12%. The number of leucocytes was increased to 32800, myeloblast (leukemic cells) was 79% which showed a positive peroxidase reaction, and Auer's bodies were seen in the cells. As a result, the patient was diagnosed as acute myelocytic leukemia. Transfusion of erythrocytes and blood platelets was carried out. The association of many drugs such as Daunomycin, Cyclocytidine, 6-MP and Predonin was also employed. Although the blood picture was improved, the patient died of a severe headache and systemic exacerbation. As autoptic findings, metastases of breast cancer, fibrosis in the marrow at the irradiation field, aggregation of leukemic cells in the femoral marrow, and infiltration of myeloblasts in the spleen were observed. It is considered that the intracranial hemorrhage following the leukemia was the cause of death. (Kanao, N.)

  14. Peritoneal bleeding due to percutaneous transhepatic gallbladder drainage: An autopsy report

    Yoko Ihama

    2012-01-01

    Full Text Available A 77-year-old man underwent percutaneous transhepatic gallbladder drainage (PTGBD for acute cholecystitis as a preoperative procedure; however, he suddenly suffered cardiopulmonary arrest 4 h after the PTGBD and died. There were three centesis scars for the PTGBD, and only one pathway from the most dorsal centesis scar reached the gallbladder. Microscopically, the PTGBD pathway crossed and injured the intrahepatic arterial wall, and hepatic parenchymal bleeding extended along the PTGBD pathway to the inferior surface of the liver. Blood flowed to the peritoneal cavity through a small gap between the liver and gallbladder. Consequently, the PTGBD caused lethal bleeding. When the percutaneous transhepatic cholangio drainage/PTGBD pathway runs close to vessels near the liver surface, it might be necessary to deal with the possibility of rapid and lethal peritoneal bleeding.

    Full Text Available Prepared by: Cy Schoenfield, Janet Brown, Joe Woodard, Jeff Brown, Martin Brown, Charles Turner, Jill Hill Published in 1970 by Student Research Facility, Berkeley, California Reproduced from the US Heath Activism History Collection Rare Book and Manuscript Library, University of Pennsylvania "The United States (has a quality of medical care unsurpassed anywhere," said Dr. Milford O. 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. But does it, really?"

    New bathymetric and magnetic anomaly data from the Phoenix Ridge, Antarctica, show that extinction of all three remaining segments occurred at the time of magnetic chron C2A (3.3 ± 0.2 Ma), synchronous with a ridge-trench collision south of the Hero Fracture Zone. This implies that the ultimate cause of extinction was a change in plate boundary forces occasioned by this collision. Spreading rates slowed abruptly at the time of chron C4 (7.8 ± 0.3 Ma), probably as a result of extinction of the...

  17. Development of paradigm for the study of amino acid neurotransmitter release in human autopsy brain samples

    Full text: This study attempted to establish a release protocol to characterize both the vesicular and cytoplasmic components of amino acid transmitter release in human synaptosomes. Experiments with rat synaptosomes showed that, with depolarizing concentrations of K+ ions, vesicular release could be successfully differentiated from cytoplasmic release for preloaded L-[3H ]glutamate and [14C ]GABA. However, human tissue studies did not give clear-cut results. Experiments were carried out to optimize the release paradigm as well as to improve the vesicular uptake of labeled transmitters. A 'pulse- chase' protocol, with an unlabelled D-aspartate chase, was performed in human tissue samples in order to enhance the L-[3H ] glutamate release signal derived from exocytosis by removing the cytoplasmic pool of L-[3H ] glutamate first. However, the results showed that total release was not enhanced effectively in comparison with the non-pulse-chase protocol. In brief, the pulse-chase protocol did not build up the vesicular pool of L-[3H ]glutamate, though the cytoplasmic L- [3H ] glutamate pool was effectively depressed by D-aspartate. Further studies applied 4- aminopyridine (4-AP) to trigger release, to circumvent the problem of the reversal of plasma membrane transporters caused by raised K+ ion concentrations. The results showed that the application of 4-AP elicited the release of amino acid transmitters from rat synaptosomes, but failed to produce successful release signals in the human tissue experiments. Our findings suggest that the vesicular compartment may be impaired by freezing and affected by post-mortem delay (PMD). Rat studies showed that the freezing step had a major effect on Ca 2+-dependent release, as less L- [3 H ]glutamate and [14C ]GABA were released from the frozen rat tissue preparations. Moreover, there was an indication of a decline in L-[3H ]glutamate release with increasing PMD. Copyright (2001) Australian Neuroscience Society

  18. Katrina's Social Autopsy: How Many Died, Who Were They, Why did They Perish?

    Mutter, J. C.; R'id, A.; Holthaus, E.

    2006-12-01

    Nature cannot know where the poorest people in the world live, yet by a vast margin the poor outnumber the rich in the count of deceased victims in earthquakes, floods, and virtually all natural disasters with the exception of droughts that today only take lives in poor countries. Establishing just how many people die in a disaster and the circumstances of their deaths has proven to be an elusive quest. For the Katrina catastrophe we must count all those who drowned or were crushed in their homes, but should those who died taking refuge in the Superdome be included in the death toll, as well as those who died from a prior condition fatally aggravated by the stress of the disaster? In the August heat wave in New York very few people are said to have died because only those who succumbed to the medically determined condition of heat stroke were considered victims. The death toll in the very similar heat wave in Chicago in 1995 exceeded 500 because the definition of deceased victims included a broader range of causes of death. In New Orleans and Chicago the poorest among us, the oldest, and those living alone made up the overwhelmingly largest group of deceased victims. Honest counting leads to much larger figures than typical official statistics. These mortality risk factors echo the global realities of disaster vulnerability in which the poorest countries face the greatest losses of life and the greatest developmental setbacks. Regrettably, social class is the prime determinant of disaster mortality risk. Any realistic scenario of natural disaster human outcomes must take this uncomfortable reality into account.

    2012-01-01

    Myocardial bridging is a congenital coronary anomaly with a variety of clinical manifestations. Traditionally, myocardial bridging has been considered a benign condition, but some cases of myocardial ischemia, infarction and sudden cardiac death due to myocardial bridging have been reported. Various studies have suggested that in their intramyocardial segments, these vessels are protected from obstructive atherosclerosis, with atherosclerosis being present in the proximal part of the artery. ...

    Full Text Available Dr. Jacob Churg (1910-2005 was born in Dolhinow, a Belarusian city that later became a part of Poland and in 1939 was ceded to Russia during the partition of Poland by Russia and Germany. Churg’s father, Wolf, was a physician, and his mother, Gita, a dentist. Jacob recalled reading his father’s medical books and pestering him with many questions. He graduated with a medical degree from the University of Wilno (Poland in 1933 and started working at the Department of Internal Medicine. He realized that he was less confident dealing with patients than with “tissues.” In 1936, at the same university, he began his studies in experimental pathology.
