Leigh syndrome in an infant: autopsy and histopathology findings

Leigh syndrome is an inherited neurodegenerative disorder of infancy that typically manifests between 3 and 12 months of age. The common neurological manifestations are developmental delay or regression, progressive cognitive decline, dystonia, ataxia, brainstem dysfunction, epileptic seizures, and respiratory dysfunction. Although the disorder is clinically and genetically heterogeneous, the histopathological and radiological features characteristically show focal and bilaterally symmetrical, necrotic lesions in the basal ganglia and brainstem. The syndrome has a characteristic histopathological signature that helps in clinching the diagnosis. We discuss these unique findings on autopsy and radiology in a young infant who succumbed to a subacute, progressive neurological illness suggestive of Leigh syndrome. Our case highlights that Leigh syndrome should be considered in the differential diagnosis of infantile-onset, subacute neuroregression with dystonia and seizures, a high anion gap metabolic acidosis, normal ketones, elevated lactates in blood, brain, and urine, and bilateral basal ganglia involvement.

Patología y salud pública: Oportunidades para el avance / Pathology and public health: opportunities for progress

La patología y la salud pública son disciplinas que se complementan en múltiples formas, desde la información que aportan mutuamente a niveles individual y poblacional, hasta la elaboración de políticas públicas en salud y la gestión de la información en los biobancos, así como la articulación para respuesta en emergencias y brotes. En revisión no sistemática resaltamos que los dos campos de mayor colaboración con la salud pública son la patología forense (comprendiendo muertes violentas y no violentas) y la patología molecular, realizando aportes significativos a la planeación de los servicios de salud, la calidad de la información epidemiológica, la salud pública basada en la evidencia que permite una mejor toma de decisiones, y la gestión de la salud comunitaria y poblacional. A partir de la revisión realizada se identificaron como puntos de mejora el uso de los sistemas de información, la necesidad de un enfoque interdisciplinario más tangible, y la urgente transformación educativa que subyace a esta colaboración.

Pathology and public health are disciplines that complement each other in many ways, from the information they provide to each other at the individual and population levels, to the development of public health policies and the management of information in biobanks, as well as articulation in responding to emergencies and outbreaks. Our non-systematic review highlights that the two most relevant fields which collaborate with public health are forensic pathology (including violent and non-violent deaths) and molecular pathology, making significant contributions to health care planning, the quality of epidemiological information, evidence-based public health that enables better decision-making, and community and population health management. This review identified the use of information systems, the need for a more tangible interdisciplinary approach, and the urgent educational transformation that underlies this collaboration, as areas for improvement.

Autopsias en fallecidos de la tercera edad / Autopsies in elderly deceased elderly

Introducción: La Organización Mundial de la Salud promueve un compromiso con el envejecimiento saludable. La autopsia constituye el método más completo para el estudio de las enfermedades, y en los fallecidos de la tercera edad se evidencian sus problemas de salud. Objetivo: Mostrar las particularidades en edad, sexo, enfermedades crónicas, en particular los tumores malignos, la sepsis y causas de muerte que se encuentran en las autopsias de fallecidos de la tercera edad. Método: se realizó un estudio retrospectivo, longitudinal, entre los años 1987-2017 de las autopsias en fallecidos de la tercera edad. Se agrupan por edades: edad avanzada, anciana y grande longeva. Se exploran las variables de edad y sexo, enfermedades crónicas, infección y causas de muerte. Resultados: Los fallecidos de la tercera edad constituyen más de las tres cuartas partes de las autopsias en la institución. El sexo femenino muestra mayor longevidad. La hipertensión arterial, diabetes y el cáncer decrecen con la edad, mientras la sepsis se incrementa. Aumentan progresivamente en las causas de muerte directa, la sepsis y el tromboembolismo, mientras disminuyen el choque, edema pulmonar e infarto cardiaco. Aumenta en las causas básicas la aterosclerosis cerebral y generalizada, disminuye la coronaria, la enfermedad hipertensiva y los tumores malignos. La no coincidencia clínico patológica aumenta con la edad, discretamente. Conclusiones: Existen particularidades en el estudio de los pacientes de la tercera edad, evidenciado por los resultados de autopsia, por lo que se recomienda la geriatrización de los servicios(AU)

Introduction: The World Health Organization promotes a commitment to healthy aging. The autopsy is the most complete method for the study of the diseases and in the elderly deceased their health problems are evidenced. Objective: To show the particularities in ages, sex, chronic diseases, in particular malignant tumors, sepsis and causes of death found in the autopsies of the deceased elderly people. Method: A retrospective, longitudinal study was carried out between the years 1987-2017 of autopsies in elderly deceased. They were grouped by age: advanced age, elderly and long-lived. The variables age, sex, chronic diseases, infection and causes of death were explored. Results: The elderly deceased were more than three quarters of the autopsies in the institution. The female sex showed greater longevity. Hypertension, diabetes and cancer decreased with age, while sepsis increased. Sepsis and thromboembolism were progressively increasing in the direct causes of death, while shock, pulmonary edema and cardiac infarction decreased. In basic causes, cerebral and generalized atherosclerosis increased and coronary atherosclerosis, hypertensive disease and malignant tumors decreased. The clinical - pathology no coincidence, increased slightly with age. Conclusions: There are particularities in the studies of elderly patients evidenced by the results of autopsy, so that geriatrification of services is necessary(AU)

Autopsy of a child with Spinal muscular atrophy Type I (Werdnig-Hoffmann disease)

Spinal muscular atrophy (SMA) is a heritable neuromuscular disorder which encompasses a large group of genetic disorders characterized by slowly progressive degeneration of lower motor neurons. The mutation is seen in the SMN1 gene mapped on chromosome 5. Depending on the age of the onset and the degree of severity, SMA has three subtypes. We discuss the autopsy findings in a case of Type 1 SMA also known by the name Werdnig-Hoffmann disease, to highlight the primary changes in the spinal cord, and skeletal muscle with association changes in the liver and terminal respiratory complications.

The grim reaper evading modern medicine: aspergillosis, adenovirus, and Hodgkin lymphoma

Illustrative cases of diseases that are difficult to suspect and diagnose can serve as useful reminders. Invasive pulmonary aspergillosis and adenovirus hepatitis are two such diseases, both revealed by autopsy in this case of Hodgkin lymphoma refractory to chemotherapy treated with allogeneic hematopoietic stem cell transplantation complicated by these two fatal infections. This patient was cured of Hodgkin lymphoma, Clostridioides difficile colitis and thrombotic thrombocytopenic purpura using the marvels of modern medicine. This case illustrates many features of aspergillosis and adenovirus hepatitis, shows the value of autopsy in revealing diagnoses, and illustrates the limits of modern medicine, which should serve as a mental spur in our efforts to advance medical science, to try to defeat the numerous demons of disease, who seem to keep outwitting us.

Mortality in adolescents and young adults with chronic diseases during 16 years: a study in a Latin American tertiary hospital / Mortalidade entre adolescentes e adultos jovens com doenças crônicas durante 16 anos: estudo em um hospital terciário da América Latina

ABSTRACT Objectives: To evaluate mortality in adolescents and young adult patients with chronic diseases followed in a Latin American tertiary hospital. Methods: A cross-sectional retrospective study was performed in a tertiary/academic hospital in the state of São Paulo, Brazil. Death occurred in 529/2850 (18.5%) adolescents and young adult patients with chronic diseases, and 25/529 (4.7%) were excluded due to incomplete medical charts. Therefore, 504 deaths were evaluated. Results: Deaths occurred in 316/504 (63%) of early adolescent patients and in 188/504 (37%) of late adolescent/young adult patients. Further comparisons between early adolescents (n = 316) and late adolescent/young adult patients (n = 188) with pediatric chronic diseases at the last hospitalization showed that the median disease duration (22.0 [0-173] vs. 43.0 [0-227] months, p < 0.001) was significantly lower in early adolescents vs. late adolescent/young adult patients. The median number of previous hospitalizations was significantly lower in the former group (4.0 [1-45] vs. 6.0 [1-52], p < 0.001), whereas the last hospitalization in intensive care unit was significantly higher (60% vs. 47%, p = 0.003). Regarding supportive measures, palliative care was significantly lower in the younger group compared to the older group (33% vs. 43%, p = 0.02). The frequencies of renal replacement therapy (22% vs. 13%, p = 0.02), vasoactive agents (65% vs. 54%, p = 0.01), and transfusion of blood products (75% vs. 66%, p = 0.03) were significantly higher in the younger group. The five most important etiologies of pediatric chronic diseases were: neoplasias (54.2%), hepatic diseases/transplantation (10%), human immunodeficiency virus (5.9%), and childhood-onset systemic lupus erythematosus and juvenile idiopathic arthritis (4.9%). Autopsy was performed in 58/504 (11%), and discordance between clinical and postmortem diagnoses was evidenced in 24/58 (41.3%). Conclusions: Almost 20% of deaths occurred in adolescents and young adults with distinct supportive care and severe disease patterns. Discordance between clinical diagnosis and autopsy was frequently observed.

RESUMO Objetivos: Avaliar a mortalidade entre adolescentes e pacientes adultos jovens com doenças crônicas acompanhados em um hospital terciário na América Latina. Métodos: Foi feito um estudo retrospectivo transversal em um hospital terciário/universitário no Estado de São Paulo, Brasil. Houve mortalidade de 529/2.850(18,5%) pacientes adolescentes e adultos jovens com doenças crônicas, porém 25/529(4,7%) foram excluídos devido a prontuários médicos incompletos. Portanto, foram avaliados 504 óbitos. Resultados: Ocorrem 316/504(63%) óbitos entre pacientes no início da adolescência e 188/504(37%) pacientes no fim da adolescência/adultos jovens. As comparações adicionais entre os pacientes no início da adolescência (n = 316) e no fim da adolescência/pacientes jovens (n = 188) com doenças crônicas pediátricas na última internação mostraram que a duração média da doença [22,0 (0-173) em comparação com 43,0 (0-227) meses, p < 0,001], foi significativamente menor nos pacientes no início da adolescência em comparação com os pacientes no fim da adolescência/adultos jovens. O número médio de internação anterior foi significativamente menor no primeiro grupo [4,0 (1-45) em comparação com 6,0 (1-52), p < 0,001], ao passo que a última internação na unidade de terapia intensiva foi significativamente maior (60% em comparação com 47%, p = 0,003). Com relação a medidas de suporte, o cuidado paliativo foi significativamente menor no grupo de pacientes no início da adolescência em comparação com o grupo de pacientes no fim da adolescência (33% em comparação com 43%, p = 0,02). As frequências de terapia de substituição renal (22% em comparação com 13%, p = 0,02), agentes vasoativos (65% em comparação com 54%, p = 0,01) e transfusão de hemoderivados (75% em comparação com 66%, p = 0,03) foram significativamente maiores no primeiro grupo. As cinco etiologias mais importantes de doenças crônicas pediátricas foram: neoplasias (54,2%), doenças hepáticas/transplante (10%), vírus da imunodeficiência humana (5,9%), lúpus eritematoso sistêmico de início na infância e artrite idiopática juvenil (4,9%). Foi feita autópsia em 58/504 (11%) e a discordância entre os diagnósticos clínico e pós-morte foi comprovada em 24/58 (41,3%). Conclusões: Quase 20% dos óbitos ocorreram em adolescentes e adultos jovens com diferentes padrões de cuidados de suporte e doenças graves. A discordância entre o diagnóstico clínico e a necropsia foi frequentemente observada.

Introducción: entre los años 1933 y 1937, el Dr. Salvador Allende trabajó con regularidad en el servicio de Anatomía Patológica del Hospital Carlos van Buren de Valparaíso (HCVB), realizando autopsias en los casos de muertes de causa médica. Materiales y método: se revisaron los libros del servicio de Anatomía Patológica del HCVB del año 1937 y se seleccionaron las autopsias realizadas por el Dr. Allende. Los libros y autopsias de los años 1933 a 1936 no pudieron ser encontrados. Los datos demográficos de los pacientes se traspasaron a una planilla Excel. Los resultados se expresaron en números y porcentajes. Resultados: el Dr. Allende realizó 54 autopsias durante un periodo de 5 meses, lo que correspondió al 12,6% de las realizadas ese año. De los 54 pacientes, 48 (88,8%) correspondieron al sexo masculino, con un promedio de edad de 46 (9-97) años. La mayoría tenían nacionalidad chilena y estaban cesantes. El 53,7% de los casos falleció por una causa infecciosa y las más frecuentes fueron la neumonía y la tuberculosis. La concordancia entre los diagnósticos clínicos y de Anatomía Patológica fue de un 70,3%. Conclusiones: se encontró solo una parte de las autopsias realizadas por el Dr. Allende en el HCVB. La mayoría de los pacientes fallecidos fueron jóvenes del sexo masculino y cesantes. Las principales causas de muerte fueron la neumonía y la tuberculosis. (AU)

Introduction: Dr. Salvador Allende often worked between the years 1933 and 1937 for the pathology department in the Carlos van Buren Hospital, performing autopsies in the medical cause death cases. Materials and Methods: the pathology department books from 1937 were reviewed searching for the autopsies performed by Dr. Allende and those were selected. The books and autopsies of the years 1933-1936 could not be found. The demographic data about patients were transfered into an excel spreadsheet. The results were expressed as numbers and percentages. Results: Dr. Allende performed 54 autopsies over a period of 5 months, which corresponded to 12.6% of all the autopsies performed that year. Of the 54 patients, 48 were male (88.8%), with an average age of 46 (9-97) years. Most of them had Chilean nationality and unemployed. 53.7% of studied cases died by an infectious cause being the most common pneumonia and tuberculosis. The concordance between clinical diagnoses and pathology department were 70.3%. Conclusions: Only a small part of the autopsies performed by Dr. Salvador Allende in HCVB was found. Most deceased patients were young men and unemployed. The main causes of death were pneumonia and tuberculosis.(AU)

Avaliação da investigação de óbitos por causas mal definidas no estado da Bahia, Brasil, em 2010 / Assessment of the investigation of deaths from ill-defined causes in the state of Bahia in 2010

Resumo A investigação de óbitos por causas mal definidas (CMD) tem sido uma estratégia utilizada pelos serviços de saúde para redução do percentual destes óbitos. Este estudo teve como objetivo avaliar a adesão dos municípios na utilização de formulários preconizados na investigação de óbitos por CMD e o impacto destas investigações na redução percentual desses óbitos no Sistema de Informações sobre Mortalidade. Analisou-se a utilização dos formulários Investigação do Óbito com Causa Mal Definida (IOCMD) e autópsia verbal (AV), e o percentual de reclassificação da causa básica (CB) de morte após as investigações, em uma amostra probabilística de 27 municípios no Estado da Bahia e a capital Salvador, no ano de 2010. Dos 27 municípios da amostra, aproximadamente 50% investigaram os óbitos por CMD utilizando-se os formulários preconizados. Foram identificados 1092 óbitos por CMD, dos quais 53,1% foram investigados: em 40,5% dos casos utilizou-se apenas o formulário IOCMD, apenas o formulário AV em 15,3%, e ambos os formulários em 14,3% dos casos. A investigação dos óbitos por CMD possibilitou a redução do percentual desses óbitos de 16,5% para 9,9%, e mostrou-se mais efetiva quando realizada utilizando-se os formulários preconizados.

Abstract The investigation of deaths from ill-defined causes (DIDC) has been a strategy of health services to reduce the proportion of these events. This study aimed to estimate the adherence of municipalities to the use of recommended forms in the investigation of DIDC and the impact of these investigations on the reduction of these deaths in the Mortality Information System. The use of the Investigation of Death from Ill-defined Cause (IOCMD) and Verbal Autopsy (VA)forms and the proportion of reclassified underlying cause of death following investigations were analyzed in a probabilistic sample of 27 municipalities of Bahia state, and its capital Salvador, in 2010. Of the 27 municipalities, approximately 50% used the recommended forms to investigate DIDCs. Of the 1,092DIDCs in the sample, 53.1% were investigated: in 40.5% of the cases, only the IOCMD form was used; in 15.3%, only the VA form was used; and both forms were used in 14.3% of the cases. The investigation of DIDCs reduced the percentages of these deaths from 16.5% to 9.9% and proved to be more effective when performed using the recommended forms.

Improving the usefulness of mortality data: reclassification of ill-defined causes based on medical records and home interviews in Brazil / Aprimorando dados de mortalidade: reclassificação de causas mal definidas baseada em registros clínicos/entrevistas domiciliares no Brasil

ABSTRACT Introduction: Brazil presented a high proportion of ill-defined causes of death (IDCD) in 2000, compromising accurate cause-of-death analysis. Objective: To analyze specific underlying causes for deaths originally assigned as IDCD in the Mortality Information System (SIM - Sistema de Informação sobre Mortalidade), after investigation activities implemented in country between 2006 and 2017. Method: For all IDCD identified in the SIM, municipal health professionals collected information about the final disease obtained from hospital records, autopsies, forms of family health teams, and home investigation. Specific causes among reclassified IDCD after investigation were evaluated according to age groups and four calendar periods. Results: Proportions of IDCD reassigned to other causes after review increased over time, reaching 30.1% in 2017. From a total of 257,367 IDCD reclassified in 2006-2017, neonatal-related conditions, injury, ischemic heart disease and stroke were the leading causes detected in the age groups 0-9 years, 10-29 years, 30-69 years, 70 years and over, respectively. Discussion: The similarity and plausibility of cause-specific proportions derived from the reclassification of IDCD by age group over time indicate the accuracy of the investigation data. Conclusion: High proportions of IDCD reassigned to more informative causes after review indicate the success of this approach to correct misclassification in the SIM, an initiative that should be maintained. Training physicians on death certification along with better quality of medical care and access to health services would lead to further improvement.

RESUMO Introdução: As proporções de causas de morte mal definidas (CMD) foram elevadas no Brasil em 2000. Objetivo: Analisar causas específicas para óbitos originalmente como CMD no Sistema de Informação sobre Mortalidade (SIM), após investigação implementada no país entre 2006 e 2017. Metodologia: Para as CMD identificadas no SIM, profissionais das secretarias de saúde coletaram informações sobre a doença final obtida nos registros hospitalares, autópsias, formulários de equipes de saúde da família e investigação domiciliar. Causas específicas entre as CMD reclassificadas após investigação foram avaliadas segundo idade em quatro períodos. Resultados: Proporções de CMD reclassificadas para outras causas após revisão aumentaram ao longo do tempo, atingindo 30,1% em 2017. De um total de 257.367 CMD reclassificadas entre 2006 e 2017, causas perinatais, causas externas, cardiopatia isquêmica e doença cerebrovascular foram os principais grupamentos de causas nos grupos etários de 0-9 anos, 10-29 anos, 30-69 anos, 70 anos ou mais, respectivamente. Discussão: A similaridade e a plausibilidade das proporções de causas específicas detectadas entre as CMD nos grupos etários ao longo do tempo indicam acurácia dos dados da investigação. Conclusão: Causas mais informativas detectadas após a revisão das CMD indicam o sucesso dessa abordagem para corrigir erros de classificação no SIM, que deve ser mantida. Maior capacitação dos médicos no preenchimento do atestado de óbito e melhor acesso e qualificação dos serviços de saúde são importantes para melhoria futura.

Devido à ausência de um banco de dados demográficos da população canina que habita a Região Central do Rio Grande do Sul (RS) e à necessidade em se estabelecer uma "população controle" para a melhor interpretação da prevalência das doenças diagnosticadas pelo Laboratório de Patologia Veterinária (LPV-UFSM) da Universidade Federal de Santa Maria (UFSM), este estudo objetivou realizar uma análise das características relacionadas à raça, ao gênero e à idade dos cães necropsiados neste serviço de diagnóstico ao longo de 50 anos (1964-2013). Para isto, os laudos de necropsias de cães, realizadas entre 1964 e 2013, foram revisados, e deles foram retiradas informações referentes ao gênero, à idade e às raças de todos os cães oriundos dos municípios que compõem a Região Central do RS. Ao todo, 7.780 cães foram necropsiados; desses, 469 (6%) na primeira década (1964-1973), 1.133 (14,6%) na segunda década (1974-1983), 1.334 (17,1%) na terceira década (1984-1993), 1.705 (22%) na quarta década (1994-2003) e 3.139 (40,3%) na quinta década (2004-2013). Do total de cães com gênero informado nos laudos, 52,6% eram machos e 47,4% eram fêmeas. A mediana da idade de morte foi de três anos. Dos cães cuja raça foi informada nos laudos, 59,8% eram de raça definida (RD) e 40,2% não tinham raça definida (SRD). As raças de porte grande ou gigante mais frequentes foram: Pastor Alemão (17,2%), Boxer (6,9%), Rottweiler (5,3%), Fila Brasileiro (4,6%), Pointer Inglês (3,9%), Collie Pelo Longo (3,7%) Dobermann (3,7%) e Labrador Retriever (2,1%). As raças de porte pequeno ou médio mais frequentes foram: Poodle (8,9%), Dachshund (6,3%), Pinscher Miniatura (5,6%), Cocker Spaniel Inglês (4,5%), Pequinês (3,4%), Yorkshire Terrier (3,3%) e Terrier Brasileiro (2,8%). Houve um aumento na proporção de fêmeas e um crescimento na mediana referente à idade de morte ao longo das cinco décadas avaliadas. Apesar de não ter havido um aumento relevante na proporção de cães de RD em comparação com os SRD, observaram-se algumas mudanças na ocorrência de diferentes raças ao longo do tempo, incluindo principalmente uma dramática diminuição na percentagem de Pequinês, Terrier Brasileiro, Pointer Inglês e Pastor Alemão, e um aumento marcado na percentagem de Poodle, Dachshund, Rottweiler e Labrador Retriever. Os resultados aqui apresentados servirão como um subsídio comparativo para futuros estudos retrospectivos sobre prevalência de doenças em cães da Região Central do RS, auxiliando para uma mais correta compreensão e interpretação dos resultados encontrados nesses levantamentos de dados.(AU)

Based on the lack of demographic database on the canine population living in the midland region of Rio Grande do Sul State, Brazil, and on the need for a "control population" in the accomplishment of several prevalence-based studies of different diseases diagnosed at the Laboratório de Patologia Veterinária (LPV) of the Universidade Federal de Santa Maria (UFSM), the objective of this study was to describe the breed, gender and age characteristics of the population of dogs necropsied in this diagnostic service over 50 years (1964-2013). The protocols of necropsies performed on dogs and recorded in the LPV-UFSM between 1964 and 2013 were reviewed, and information related to gender, age and breed from dogs from all the districts within the Central Region of RS were separated. A total of 7,780 dogs were necropsied, among which 469 (6%) were registered in the first decade (1964-1973), 1,133 (14.6%) in the second decade (1974-1983), 1,334 (17.1%) in the third decade (1984-1993), 1,705 (22%) in the fourth decade (1994-2003) and 3,139 (40.3%) in the fifth decade (2004-2013). Of dogs whose gender was reported in the protocols, 52.6% were males and 47.4% were females. The median age of death was 3 years. Of dogs whose breed was reported in the protocols, 59.8% were purebred and 40.2% were mixed breed. The most common large and giant breed dogs were German Shepherd Dog (17.2%), Boxer (6.9%), Rottweiler (5.3%), Fila Brasileiro (4.6%), English Pointer (3.9%), Collie Rough (3.7%), Dobermann (3.7%), and Labrador Retriever (2.1%). The most common small and medium breed dogs were Poodle (8.9%), Dachshund (6.3%), Miniature Pinscher (5.6%), English Cocker Spaniel (4.5%), Pekingese (3.4%), Yorkshire Terrier (3.3%), and Brazilian Terrier (2.8%). The percentage of females and the median age of death showed an increase during the five decades of this study. Although there has been a significant increase in the proportion of pure breed dogs compared to mongrels, we observed some changes in the occurrence of different breeds over time, including a significant decrease in the frequency of the Pekingese, Brazilian Terrier, English Pointer, and German Shepherd Dog, and significant increase in the frequency of the Poodle, Dachshund, and Labrador Retriever. The results presented here will serve as an allowance for future comparative studies of disease prevalence in dogs of Central Region of RS, helping to a more correct understanding and interpretation of results from these data surveys.(AU)

Mortalidad prenatal en el Centro Hospitalario Pereira Rossell, Montevideo. Análisis de 845 casos de autopsia entre 2005 y 2016 / Stillbirth at Pereira Rossell Hospital in Montevideo. Analysis of 845 autopsies between 2005 and 2016

Resumen: Antecedentes: con la mejora de la atención del embarazo se ha reducido el número de mortinatos en el mundo desarrollado. Pero en los países subdesarrollados y en vías de desarrollo constituyen un problema sanitario. Objetivo: conocer las patologías que subyacen en los casos de autopsia de mortinatos del Centro Hospitalario Pereira Rossell, a los efectos de contribuir a la reducción de la mortalidad fetal. Material y método: se realiza un estudio observacional, descriptivo de recolección de información en forma retrospectiva de las autopsias de los de mortinatos del Centro Hospitalario Pereira Rossell de los últimos 12 años (2005-2016). Las autopsias y las placentas fueron realizadas de acuerdo al protocolo habitual en patología perinatal. Los datos del estudio se analizaron conjuntamente. Resultados: se constataron malformaciones congénitas en 17,7% e infección congénita en la autopsia en 20,4%. La infección en conjunto (en autopsia y/o placenta) se identificó en 383 casos (45,3%). Se identificó lúes en 10,5% de los mortinatos. Había elementos fetales de asfixia en 11,5% y una miscelánea de patologías en 3,5% de los casos. En 50,4% la autopsia propiamente dicha no tenía alteraciones, pero en 90% de ellas se identificaron lesiones placentarias que pudieron ser responsables de la muerte fetal. Se observó bajo flujo sanguíneo útero placentario en 14,2% de las placentas, corioamnionitis en 30,5% de las placentas, y hematoma retroplacentario en 26,6% de las placentas. La muerte fue indeterminada en 4,9% de los casos. Conclusiones: un elevado porcentaje de los casos tienen patologías evitables y tratables. Se identificaron patologías potencialmente recurrentes y enfermedades que ameritan tratar a la madre. Los estudios de los mortinatos deben ser considerados en los protocolos sanitarios a los efectos de reducir la mortalidad fetal.

Summary: Background: the number of stillbirth cases has been reduced in the developed countries due to improvements in pregnancy care. It is important to know the causes in order to prevent fetal death. Early identification of risk factors for stillbirth may reduce the number of cases. The objective of this paper is to identify the underlying pathologies of the cases that underwent an autopsy at Pereira Rossell Hospital in Montevideo, in order to contribute to the reduction of fetal mortality. Methods: this is a retrospective and descriptive study of autopsy and placental examinations, performed at the Pediatric Pathology Laboratory of Pereira Rossell Hospital in Montevideo. A standard protocol was applied. Data were analyzed overall. Results: congenital malformations were identified in 17.7% of cases; congenital infection in the fetus was found in 20.4%. Infection altogether (in the autopsy and/or the placenta) was identified in 383 cases (45.3%). Syphilis was diagnosed in 10.5% of the stillborn. Fetal evidence of asphyxia accounted for 11.5% and miscellaneous pathologies 3.5%. In 50.4% of cases the autopsy did not reveal alterations, but 90% of corresponding placentas had lesions that could have caused the death of the fetus. Maternal underperfusion or malperfusion was found in 14.2% of the placentas. Chorioamnionitis was seen in 30.5%. A retroplacental hematoma was seen in 26.6%. Stillbirth was of unexplained in 4.9% of the cases. Conclusion: a high percent of the cases studied had a preventable pathology. Many recurrent lesions were identified as well as cases that required additional medication to the mother. The results of the pathology examination should be considered in order to reduce the stillbirth rate.

Cómo descifrar el suicidio y otros tipos de muerte asociados a la intoxicación por drogas: Consulta de los Centros para el Control y la Prevención de Enfermedades. Resumen de la reunión

La clasificación del tipo de muerte (es decir, por causas naturales o por accidente, suicidio, homicidio o causa indeterminada) afecta tanto la vigilancia de la mortalidad como las investigaciones, políticas y prácticas de salud pública. La determinación del tipo de muerte en el caso de defunciones debidas a la intoxicación por drogas puede ser más difícil, dada la marcada variabilidad entre los estados dentro de Estados Unidos. Los Centros para el Control y la Prevención de Enfermedades (CDC) de Estados Unidos organizaron una reunión multidisciplinaria para debatir el tema de las muertes debidas a intoxicación por drogas en relación con el suicidio y otros tipos de muerte. Los objetivos de la reunión fueron determinar los factores a nivel individual, del sistema y del lugar que afectan la clasificación del tipo de muerte y proponer posibles soluciones a los obstáculos para la clasificación. Entre las estrategias sugeridas se mencionaron: una mejor estandarización de las prácticas de investigación de la escena de muerte, toxicología y autopsia; una mayor rendición de cuentas; y la creación de guías de ayuda para los investigadores. Se necesita de la colaboración y coordinación continuas de las actividades entre los interesados directos en apoyo a los esfuerzos de prevención.

Manner of death (MOD) classification (i.e., natural, accident, suicide, homicide, or undetermined cause) affects mortality surveillance and public health research, policy, and practice. Determination of MOD in deaths caused by drug intoxication is challenging, with marked variability across states. The Centers for Disease Control and Prevention hosted a multidisciplinary meeting to discuss drug intoxication deaths as they relate to suicide and other MOD. The meeting objectives were to identify individual-level, system-level, and place-based factors affecting MOD classification and identify potential solutions to classification barriers. Suggested strategies included improved standardization in death scene investigation, toxicology, and autopsy practice; greater accountability; and creation of job aids for investigators. Continued collaboration and coordination of activities are needed among stakeholders to affect prevention efforts.

Diagnóstico de necrosis tubular aguda en pacientes egresados fallecidos / Diagnosis of acute tubular necrosis in deceased patients

Introducción: el diagnóstico histopatológico de necrosis tubular aguda, generalmente de causa isquémica o nefrotóxica, se encuentra muy relacionado con el desarrollo de insuficiencia renal aguda. Objetivo: analizar la presencia de diagnóstico histopatológico de necrosis tubular aguda en los egresados fallecidos autopsiados y explorar la relación con posibles factores favorecedores. Métodos: estudio retrospectivo, observacional de las autopsias en el Hospital Militar Central Dr. Luis Díaz Soto, en el período 1962 al 2015. Se estableció en ellas el diagnóstico histopatológico de necrosis tubular aguda y se analizó el comportamiento de variables demográficas, clínicas y anatomopatológicas. Resultados: se registraron 843 341 egresados, de ellos 25 213 fallecidos (índice de mortalidad 3,0), se realizaron 18 630 autopsias (índice autopsia 75,3 por ciento), en estas se estableció diagnóstico de necrosis tubular aguda en 6.264 (33,6 por ciento). Predominaron los pacientes masculinos y los mayores de 45 años de edad. El shock (22,3 por ciento), la bronconeumonía (16,3 por ciento), la aterosclerosis coronaria(18,5 por ciento) y el edema pulmonar (11,3 por ciento) constituyeron las principales causas directas de muerte. La aterosclerosis coronaria (18,5 por ciento) fue la principal causa básica de muerte. Conclusiones: se registró un incremento sostenido de egresos, de fallecidos y de autopsias practicadas, así como del diagnóstico histopatológico de necrosis tubular aguda. Predominaron los pacientes del sexo masculino y aquellos mayores de 45 años de edad. Las principales causas directas de muerte en estos fueron el shock, la bronconeumonía y el edema pulmonar. La aterosclerosis fue la principal causa básica de muerte(AU)

Introduction: The histopathological diagnosis of acute tubular necrosis, usually of ischemic or nephrotoxic cause, is closely related to the development of acute renal failure. Objective: To analyze the presence of histopathological diganosis of acute tubular necrosis in deceased autopsied and to explore the relationship with possible favoring factors. Method: Retrospective, observational study, with descriptive statistical study of the autopsies at the Central Military Hospital Dr. Luis Díaz Soto in the period from 1962 to 2015. The histopathological diagnosis of acute tubular necrosis was done and demographic, clinical and anatomopathological variables were analyzed. Results: 843 341 discharged from hospital were recorded, of which 25 213 died (mortality rate 3.0), 18 630 autopsies were performed (autopsy rate 75.3 percent). In these cases a diagnosis of acute tubular necrosis was done in 6 264 (33.6 percent). Male patients and those over 45 years of age predominated. Shock (22.3 percent), bronchopneumonia (16.3 percent), coronary atherosclerosis (18.5 percent) and pulmonary edema (11.3 percent) were the main direct causes of death. Coronary atherosclerosis (18.5 percent) was the main underlying cause of death. Conclusions: There was a sustained increase in discharged patients, deaths and autopsies, as well as the histopathological diagnosis of acute tubular necrosis. Male patients predominated and those older than 45 years of age. The main direct causes of death in these were shock, bronchopneumonia and pulmonary edema. Atherosclerosis was the leading cause of death(AU)

Caracterización anatomopatológica de los neonatos fallecidos durante el quinquenio 2010-2014 / Pathological characterization of dead neonates during 2010-2014

Se realizó un estudio transversal y retrospectivo de los 55 neonatos autopsiados en el Departamento de Anatomía Patológica del Hospital General Dr Juan Bruno Zayas Alfonso de Santiago de Cuba, durante el quinquenio 2010-2014, para identificar las características anatomopatológicas que permitieran determinar las causas de las defunciones y describir los factores maternos y neonatales concurrentes en estas últimas. Entre los principales hallazgos sobresalió el predominio de estos decesos en el 2010, con 16; del sexo masculino (61,81 por ciento); de la muerte neonatal precoz con 32, de los nacidos pretérmino con bajo peso (94,44 por ciento), del parto por cesárea y de la preclampsia como antecedente materno. La causa básica de muerte más frecuente fue nacer antes del término con bajo peso en 30; y la causa directa de muerte, la hipoxia en 15 de ellos

A cross-sectional and retrospective study of the 55 neonates undergoing autopsy was carried out in the Pathology Department of Dr Juan Bruno Zayas Alfonso General Hospital in Santiago de Cuba, during 2010-2014, to identify the pathological characteristics that allowed to determine the causes of deaths and to describe the maternal and neonatal concurrent factors in the latter. Among the main findings the prevalence of these deaths in 2010 was significant, with 16; from male sex (61.81 percent); 32 with neonatal early death, of preterm birth with low birth weight (94.44 percent), of Caesarean delivery and of pre-eclampsia as maternal history. The most frequent basic cause of death was being born before term with low weight in 30 neonates; and the direct cause of death, hypoxia in 15 of them
