de la deglución, los cuales representan todas las alteraciones del proceso fisiológico encargado de llevar el alimento desde la boca al esófago y después al estómago, salvaguardando siempre la protección de las vías respiratorias. OBJETIVO. Definir el manejo óptimo, de la disfagia en pacientes con antecedente de infección severa por COVID-19. METODOLOGÍA. Se realizó una revisión de la literatura científica en las bases de datos PubMed y Elsevier que relacionan el manejo de la disfagia y pacientes con antecedente de infección severa por SARS-CoV-2. Se obtuvo un universo de 134 artículos que cumplieron los criterios de búsqueda. Se seleccionaron 24 documentos, para ser considerados en este estudio. RESULTADOS. La incidencia de disfagia posterior a infección severa por SARS-CoV-2 fue del 23,14%, siendo la disfagia leve la más frecuente 48,0%. Los tratamientos clínicos más empleados en el manejo de la disfagia fueron rehabilitación oral y cambio de textura en la dieta en el 77,23% de los casos, mientras que el único tratamiento quirúrgico empleado fue la traqueotomía 37,31%. Un 12,68% de pacientes recuperó su función deglutoria sin un tratamiento específico. La eficacia de los tratamientos clínicos y quirúrgicos en los pacientes sobrevivientes de la infección severa por SARS-CoV-2 fue del 80,68%, con una media en el tiempo de resolución de 58 días. CONCLUSIÓN. La anamnesis es clave para el diagnóstico de disfagia post COVID-19. El tratamiento puede variar, desde un manejo conservador como cambios en la textura de la dieta hasta tratamientos más invasivos como traqueotomía para mejorar la función deglutoria.

INTRODUCTION. The difficulty to swallow or dysphagia is included within the problems of swallowing, which represent all the alterations of the physiological process in charge of carrying the food from the mouth to the esophagus, and then to the stomach, always taking into account the protection of the airways. OBJECTIVE. To define the optimal management, both clinical and surgical, for the adequate treatment of dysphagia produced as a consequence of severe SARS-CoV-2 infection. METHODOLOGY. A review of the scientific literature was carried out using both PubMed and Elsevier databases, which relate the management of dysphagia and patients with a history of severe SARS-CoV-2 infection. RESULTS. The incidence of dysphagia following severe SARS-CoV-2 infection was of 23,14%, with mild dysphagia being the most frequent 48,00%. The most frequently used clinical treatments for dysphagia management were oral rehabilitation and change in dietary texture in 77,23% of cases, while tracheotomy was the only surgical treatment used 37,31%. A total of 12,68% of patients recovered their swallowing function without specific treatment. The efficacy of clinical and surgical treatments in survivors of severe SARS-CoV-2 infection was 80,68%, with a mean resolution time of 58 days. CONCLUSION. An adequate medical history is key to the diagnosis of post-COVID-19 dysphagia. Treatment can range from conservative management such as changes in diet texture to more invasive treatments such as tracheotomy to improve swallowing function.

Attitudes and perceptions of Filipino clinicians and pathologists towards the autopsy as a medical tool

Background@#Globally, autopsy rates have been continually declining over the course of several years. Previous studies have shown that the perception of pathologists and clinicians may serve as significant factors which may affect the performance of autopsy and contribute to its decreased rate. This study was conducted to determine the attitudes and perceptions of Filipino clinicians and pathologists toward the autopsy as a medical tool.@*Methodology@#This is a cross-sectional descriptive survey of two groups of physicians. Forty-four (n = 44) pathologists nationwide and thirty-three (n = 33) clinicians from Central Visayas participated in the study. A total of seventy-seven (n = 77) physicians completed a survey using a standardized online questionnaire.@*Results@#Of the 77 respondents, 94% of clinicians and 75% of pathologists believed that autopsies could provide relevant findings that could change future clinical practice. Despite this, only 6% of clinicians and 20% of pathologists indicated that the number of autopsy cases in their institutions was sufficient. With regards to their practice, pathologists most strongly agreed (mean = 4.30) that material for medico-legal autopsies should be readily available for teaching and research. However, they most strongly disagreed (mean = 2.00) that residents receive adequate training in performing medico-legal autopsies. The two groups of physicians surveyed determined that there is a deficiency in the number of autopsy cases. This is further influenced by clinicians’ concerns about litigation, religious/superstitious beliefs, and the delay in releasing autopsy results. Furthermore, pathologists specified that performing autopsies was excessively time-consuming with an unjustifiable cost. Sixty-two percent of the pathologists signified more strongly than the clinicians that modern diagnostic techniques have diminished the need to perform hospital autopsies. Nonetheless, 86% of Filipino physicians acknowledged that the autopsy is an important medical tool that should be performed for patients with unknown diagnoses and unexpected death. The number of observed and/or performed autopsy cases was a major factor that affected the pathologists’ attitudes and perceptions toward autopsy.@*Conclusion@#In general, there is recognition of the autopsy’s usefulness as a medical tool among the pathologists and clinicians surveyed. However, the lack of cases referred for autopsy remains a challenge undermining the benefits that are derived from its performance.

Corioamnionitis Histológica Asociada a Muerte Fetal / Histological Chorioamnionitis Associated with Fetal Death

INTRODUCCIÓN. Anualmente ocurren más de 2 millones de muertes fetales a nivel mundial, siendo fundamental el estudio anatomopatológico placentario para disminuir el número de muertes inexplicadas. OBJETIVO. Revisar la literatura existente acerca de corioamnionitis histológica, los criterios para establecer su diagnóstico, su presencia y posible asociación en estudios de causas de muerte fetal. METODOLOGÍA. Se realizaron búsquedas en bases de datos electrónicas para recopilar estudios de causas de muerte fetal que incluyeron corioamnionitis histológica. RESULTADOS. Se encontraron 13 estudios que evaluaron mortalidad fetal y que entre sus causas incluyeron corioamnionitis histológica. DESARROLLO. El estudio microscópico placentario en muertes fetales es esencial al investigar una muerte fetal. Las anomalías placentarias son la causa más común de muerte fetal, la corioamnionitis aguda es la lesión inflamatoria más frecuente. Se detallaron los criterios más relevantes para definir corioamnionitis aguda histológica pero aún no se establece un consenso. Estudios de causas de muerte fetal en años recientes han reportado corioamnionitis histológica entre 6,3% y 41,3% de casos. Las alteraciones inflamatorias del líquido amniótico son una causa importante de muerte fetal, siendo la corioamnionitis la más frecuente en este grupo. CONCLUSIÓN. En estudios para determinar las causas de muerte fetal se evidenció corioamnionitis aguda histológica en hasta el 41,3% de casos, por lo que podría estar asociada a dicho evento. Sin embargo, es necesario establecer un sistema de estadiaje de corioamnionitis histológica mediante un panel de expertos a nivel mundial.

INTRODUCTION. Annually more than 2 million fetal deaths occur worldwide, being fundamental the placental anatomopathological study to reduce the number of unexplained deaths. OBJECTIVE. To review the existing literature on histological chorioamnionitis, the criteria to establish its diagnosis, its presence and possible association in studies of causes of fetal death. METHODOLOGY. Electronic databases were searched to collect studies of causes of fetal death that included histologic chorioamnionitis. RESULTS. Thirteen studies were found that evaluated fetal mortality and that included histologic chorioamnionitis among their causes. DEVELOPMENT: Placental microscopic study in fetal deaths is essential when investigating a fetal death. Placental abnormalities are the most common cause of fetal death, acute chorioamnionitis being the most frequent inflammatory lesion. The most relevant criteria for defining histologic acute chorioamnionitis have been detailed but consensus has not yet been established. Studies of causes of fetal death in recent years have reported histologic chorioamnionitis in between 6,3% and 41,3% of cases. Inflammatory changes in the amniotic fluid are an important cause of fetal death, with chorioamnionitis being the most frequent in this group. CONCLUSIONS. In studies to determine the causes of fetal death, histological acute chorioamnionitis was evidenced in up to 41,3% of cases, so it could be associated with this event. However, it is necessary to establish a histological chorioamnionitis staging system by means of a worldwide panel of experts.

Hiperbilirrubinemia: visión del patólogo / Hyperbilirubinemia: pathologist's view

Los niveles de bilirrubina sérica normal en el adulto varían entre 0,3 mg/dL y 1,2 mg/dL, y su valor está determinado por la tasa de captación hepática, conjugación y excreción. La ictericia se hace evidente cuando los niveles de bilirrubina sérica se elevan por encima de 2,5 mg/dL a 3 mg/dL, siendo un indicador de enfermedad subyacente. La bilis es producida por los hepatocitos y fluye desde los canalículos, canales de Hering, conductos biliares intrahepáticos, conductos hepáticos derechos e izquierdos hasta llegar al duodeno. A nivel histopatológico, cualquier entidad que lleve a la acumulación intrahepática de bilis por disfunción hepatocelular u obstrucción biliar genera colestasis, que se observa en la biopsia hepática como la acumulación de tapones de color marrón verdoso de pigmento biliar en los hepatocitos, y secundariamente se observan los canalículos dilatados. Las causas de colestasis intrahepática son diversas e incluyen enfermedades como colangitis biliar primaria, colangitis esclerosante primaria, hepatitis autoinmune, hepatitis virales y toxicidad medicamentosa. Esta revisión tiene como objetivo analizar algunos tipos de hiperbilirrubinemia, resaltando sus características histopatológicas.

Normal serum bilirubin levels in adults range from 0.3 mg/dL to 1.2 mg/dL, and its value is determined by the rate of hepatic uptake, conjugation, and excretion. Jaundice becomes apparent when serum bilirubin levels rise above 2.5 mg/dL to 3.5 mg/dL and is an indicator of underlying disease. Bile is produced by hepatocytes and flows from the canaliculi, Hering's canals, intrahepatic bile ducts, and right and left hepatic ducts to the duodenum. Pathologically, any condition that leadsto intrahepatic accumulation of bile due to hepatocellular dysfunction or biliary obstruction, generates cholestasis, which is observed in liver biopsy as the accumulation of greenish-brown deposits of bile pigment in hepatocytes, with dilated canaliculi. The causes of intrahepatic cholestasis are diverse and include diseases such as primary biliary cholangitis and primary sclerosing cholangitis, autoimmune hepatitis, viral hepatitis, and drug toxicity. This review aims to analyze some types of hyperbilirubinemia, highlighting their histopathological characteristics.

Histopathological pattern of Orbito-Ocular Lesions, a retrospective hospital-based study spanning 15 years

Background: Many previous studies on orbito-ocular lesions are skewed in favour of the neoplastic lesions in general and the malignant lesions in particular. This, therefore, creates a vacuum on the spectrum of these lesions, thus may result in problematic diagnostic bias by the ophthalmologist and pathologist. Objective: To give the spectrum and relative frequencies of orbito-ocular biopsies and by extension orbito-ocular lesions/diseases at the University of Benin Teaching Hospital (UBTH). Materials and Methods: A retrospective descriptive study of all cases of orbito-ocular biopsies with histopathologic diagnosis. Results: There were 236 orbito-ocular biopsies. The male to female ratio was slightly in favour of the females. Orbito-ocular biopsies had a wide age range that spanned from the 1st to 10th decade, mean age in the 3rd decade (20-29years) and a peak age in the 1st decade (0-9 years). The neoplastic lesions were the prevalent indication for orbito-ocular biopsies (63.72%) while the conjunctiva (58.10%) was the most common site for orbito-ocular biopsies. Conclusion: This study noted a wide array of orbito-ocular lesions for which biopsies were done for histopathological diagnosis. This we hope will in no small measure increase the diagnostic precision of the ophthalmologist and the pathologists in our own environment

Hallazgos histopatológicos en biopsia renal de pacientes con COVID-19 y compromiso renal / Histopathological findings in renal biopsy of patients with COVID-19 and renal involvement

Introducción. La lesión renal aguda (LRA) en el paciente con COVID-19 ocurre más frecuentemente en presencia de enfermedades crónicas como diabetes, obesidad, hipertensión arterial y enfermedad renal crónica previa, considerándose un fuerte predictor de resultados desfavorables y mortalidad. El propósito de este estudio fue describir las características histopatológicas en biopsias renales de pacientes hospitalizados por COVID-19, que experimentaron algún grado de daño renal durante su hospitalización. Metodología. Se incluyeron 30 pacientes mayores de 18 años, hospitalizados en diferentes centros de atención en Medellín, Colombia, con diagnóstico confirmado de COVID-19, sin antecedente de terapia de reemplazo renal, que durante la infección desarrollaron algún grado de daño renal, y que tuvieran estudio histopatológico de biopsia renal. Se analizaron las características demográficas, formas clínicas de presentación y hallazgos histopatológicos a nivel renal. Resultados. La mayoría de los pacientes eran de sexo masculino (70%). Los antecedentes patológicos más frecuentes fueron la enfermedad renal crónica previa (16,7%), diabetes mellitus (16,7%), trasplante renal (13,3%) y VIH (10%). El 35,7% de los pacientes no tenían ninguna comorbilidad subyacente. La manifestación clínica inicial más frecuente fue la LRA (56,7%). Algunos pacientes tuvieron más de una manifestación clínica inicial. El 100% de los pacientes evaluados tuvieron hallazgos histopatológicos renales, siendo la nefritis tubulointersticial aguda (40%) el más frecuente. Conclusión. Nuestro estudio no descarta una posible asociación del sexo masculino con peores desenlaces en la enfermedad COVID-19. La LRA fue el hallazgo clínico inicial más frecuente. Es posible que los hallazgos histopatológicos del presente estudio puedan ser consecuencia del daño directo a nivel tubulointersticial renal y la mala perfusión renal, dado el estado de choque por la tormenta inflamatoria, el empeoramiento de enfermedades preexistentes, o la superposición clínica con otras entidades. Sin embargo, son necesarios más estudios para dilucidar los mecanismos por los cuales se generan estas lesiones

Acute kidney injury (AKI) in patients with COVID-19 occurs more frequently in the presence of chronic diseases such as diabetes, obesity, hypertension, and previous chronic kidney disease, and is considered a strong predictor of unfavorable outcomes and mortality. The purpose of this study was to describe the histopathological characteristics in kidney biopsies from patients hospitalized for COVID-19, who experienced some degree of kidney damage during their hospitalization. Methodology. We included 30 patients over 18 years of age, hospitalized in different care centers in Medellín, Colombia, with a confirmed diagnosis of COVID-19, without a history of renal replacement therapy, who developed some degree of kidney disease during the infection, and had histopathological study of renal biopsy. Demographic characteristics, clinical manifestations and histopathological findings were analyzed. Results. Most of the patients were male (70%). The most frequent previous pathological findings were chronic kidney disease (16.7%), diabetes mellitus (16.7%), kidney transplant (13.3%) and HIV (10%). 35.7% of the patients did not have any underlying comorbidity. The most frequent initial clinical manifestation was AKI (56.7%). Some patients had more than one initial clinical manifestation. 100% of the patients had renal histopathological findings, with acute tubulointerstitial nephritis (40%) being the most frequent. Conclusion. Our study does not rule out a possible association of the male gender with worse outcomes in COVID-19 disease. AKI was the most common initial clinical finding. It is possible that the histopathological findings of this study may be a consequence of direct damage at the renal tubulointerstitial level and poor renal perfusion due to the inflammatory storm, worsening of pre-existing diseases, or clinical overlap with other entities. However, more studies are needed to elucidate the mechanisms by which these lesions are generated

Ileites - endoscopistas e patologistas falam a mesma língua? / Ileitis - do endoscopist and pathologist speak the same language?

ABSTRACT BACKGROUND: Ileitis is defined as an inflammation of the ileum, which is evaluated during colonoscopy. Biopsies should be performed on altered ileus, aiding to the diagnosis. OBJECTIVE: Evaluate the correlation of anatomopathological findings on ileitis between pathologists and endoscopists. METHODS: A retrospective, cross-sectional study, between 2013 and 2017. Examination report, indications for colonoscopy, and medical records were evaluated to identify whether the colonoscopic findings were clinically significant. Anatomopathological samples were reviewed by a pathologist expert in gastrointestinal tract. Patients over 18 years of age who had undergone ileoscopy were included, whereas patients below 18 years of age and those with previous intestinal resections were excluded. The correlation was assessed using the kappa coefficient index. RESULTS: A total of 5833 colonoscopies were conducted in the study period and 3880 cases were included. Ileal alterations were observed in 206 cases, with 2.94% being clinically significant. A hundred and sixty three biopsies were evaluated using the kappa index, resulting in agreement among pathologists of 0.067 and among pathologist and endoscopist of 0.141. CONCLUSION: It was observed that despite the low concordance between pathologists and endoscopists, there was no change in patient outcomes. This study confirms the importance of knowledge of the main anatomopathological changes related to ileitis by pathologists and endoscopists, making the best diagnosis and follow-up.

RESUMO CONTEXTO: Ileíte é definida como uma inflamação ileal, que pode ser avaliada durante a colonoscopia. Biópsias devem ser realizadas em íleos alterados, acrescentando na definição diagnóstica. OBJETIVO: Avaliar a correlação de achados anatomopatológicos das ileítes entre patologistas e endoscopistas. MÉTODOS: Estudo retrospectivo, transversal, entre os anos de 2013 e 2017. Foram avaliados laudos de exames, indicações e prontuários para identificar quando os achados colonoscópicos foram significativos. As amostras de anatomopatologia foram revisadas por um patologista especialista em trato gastrointestinal. Foram incluídos pacientes acima de 18 anos, com ileoscopia, e excluídos pacientes menores de 18 anos e os com ressecções intestinais prévias. A correlação foi avaliada utilizando-se o coeficiente kappa. RESULTADOS: Durante o período do estudo foram realizadas 5833 colonoscopias, das quais 3880 foram incluídas. Alterações ileais foram observadas em 206 casos, com 2,94% sendo clinicamente significativo. Cento e sessenta e três biópsias foram avaliadas, resultando em coeficiente kappa entre patologistas de 0,067 e entre patologista e endoscopista de 0,141. CONCLUSÃO: Foi observado que a despeito da baixa concordância entre patologistas e endoscopistas, não houve mudança no desfecho clínico do paciente. Esse estudo confirma a importância do conhecimento dos achados anatomopatológicos principais das ileítes entre patologistas e endoscopias, fazendo o melhor diagnóstico e seguimento.

Calidad de la biopsia hepática en 10 instituciones hospitalarias de Bogotá / Quality of liver biopsies taken in ten hospitals of Bogotá

Resumen Introducción: La biopsia hepática es la prueba de oro para el diagnóstico de las enfermedades que comprometen el hígado, una muestra adecuada y una muy buena lectura son elementos que determinan la utilidad de la prueba y el impacto en la toma de decisiones. Objetivo: Evaluar la calidad de las biopsias hepáticas a partir de la frecuencia de un diagnóstico definitivo en la lectura de las mismas y su relación con el número de espacios porta y su longitud informada. Materiales y métodos: Estudio observacional retrospectivo basado en registros, entre el 1 de enero de 2010 y el 30 de julio de 2017. Se realizó la revisión de las historias clínicas de los pacientes a quienes se les realizó biopsia hepática y se evaluó el resultado de la patología. Resultados: Se incluyeron 659 informes de patología de 10 instituciones. El porcentaje de reporte de espacios porta varió entre un 15 % y un 87,4 %, entre las instituciones. La mediana de longitud de la biopsia fue 15 mm (rango intercuartílico [RIC]: 10-20) con el valor más bajo de 1,3 (1-1,5) y el más alto de 1,8 (1,4-2) y la del número de espacios porta fue de 10 (RIC: 7-15), con el valor más bajo de 5 (1-8) y el más alto de 13 (10-17). Los diagnósticos definitivos se presentaron entre 35 % y 69 %, diagnósticos probables entre 25 % y 63 %, y sin diagnóstico entre un 5 % y 31,8 %. En el resultado de la regresión logística del diagnóstico y análisis univariado, se encontró que el número de espacios porta presentó un Odds ratio (OR) de 1,12 (intervalo de confianza [IC] 95 %: 1,05-1,19) y la longitud, OR: 1,74 (1,06-2,87); con el análisis multivariado, el número de espacios porta sigue siendo significativo (OR: 1,12 [1,02 a 1,22], p = 0,011). Conclusiones: En Bogotá existen 3 instituciones hospitalarias con adecuada calidad preanalítica en la toma de biopsias hepáticas y diagnósticos definitivos por encima del 60 %, asociados en esta serie con la presencia de un cilindro de tejido hepático de longitud y número de espacios porta adecuados. Con el análisis multivariado, el número de espacios porta presentó significancia. Se insiste en la importancia de la experiencia y entrenamiento del patólogo que evalúa la biopsia.

Abstract Introduction: Liver biopsy is the gold-standard test for the diagnosis of diseases involving the liver. An adequate sample and an accurate reading of the report are key to determine the usefulness of the test and its impact on decision-making. Objective: To assess the quality of liver biopsies based on the frequency of a "definitive diagnosis" in their report and their association with the number of portal spaces and reported length. Materials and methods: Record-based retrospective observational study, from January 1, 2010, to July 30, 2017. A review of the medical records of patients who underwent liver biopsy was performed, and the pathology result was evaluated. Results: 659 pathology reports from 10 hospitals were included. The percentage of portal space reporting varied between 15% and 87.4%. The median biopsy length was 15mm (IQR: 10-20) and the median number of portal spaces was 10 (IQR: 7-15). Definitive diagnoses were between 35% and 69%, probable diagnoses between 25% and 63%, and no diagnosis between 5% and 31.8%. The logistic regression of the diagnosis and a univariate analysis found that the number of portal spaces had an OR of 1.12 (95%CI: 1.05-1.19), while length had an OR of 1.74 (95%CI: 1.06-2.87). The multivariate analysis showed that the number of portal spaces is significant [OR: 1.12 (95%CI:1.02 to 1.22), p = 0.011]. Conclusions: In Bogotá, there are 3 hospitals with adequate pre-analytical quality of liver biopsies and definitive diagnoses above 60%, which in this series is associated with the presence of a cylinder of liver tissue of adequate length and the number of portal spaces. Multivariate analysis showed that the number of portal spaces is significant. The importance of the experience and training of the pathologist who evaluates the biopsy is stressed.

Shapes of pathology / As formas da patologia

The shape is one of the key features of a lesion and a pathologist must be able to identify and interpret these forms in the context of any gross and microscopic changes. One of the principles of adult learning is to engage the learner with previously understood information. If, when presenting material that is new, a connection with something the student already has familiarity with, the learning process is accelerated. As the learners are already familiar with shapes they have encountered throughout their pre-pathology learning, these can be used to hasten the incorporation and understanding of lesions. This paper describes various shapes that are used in describing lesions in veterinary pathology.(AU)

A forma é uma das principais características de uma lesão. Um patologista deve ser capaz de identificar e interpretar essas formas no contexto de quaisquer alterações macroscópicas ou microscópicas. Um dos princípios da aprendizagem de adultos é envolver o aluno com informações previamente compreendidas. Se, ao apresentar um material novo, se estabelece uma conexão com algo que o aluno já conhece, o processo de aprendizagem torna-se mais rápido e eficiente. Como os alunos já estão familiarizados com as formas que encontraram ao longo de sua aprendizagem pré-patologia, elas podem ser usadas para acelerar a incorporação e a compreensão das lesões. Este artigo descreve várias formas que são usadas na descrição de lesões em patologia veterinária.(AU)

Ausculta cervical en el paciente pediátrico con parálisis cerebral Revision narrativa / Cervical auscultation in pediatric patient with cerebral palsy Narrative review

Dentro de la atención clínica, el profesional de la fonoaudiología cuenta con recursos evaluativos para describir la biomecánica secuencial de la ingesta; uno de los recursos utilizados es la Auscultación Cervical (AC). (Dudik et al., 2016) Teniendo en cuenta la descripción de la importancia de la intervención oportuna y efectiva de los procesos de alimentación en los niños con parálisis cerebral, se considera necesario resolver aspectos relevantes alrededor de la relación de las características clínicas de estos niños en su proceso de deglución y los registros del perfil espectrográfico en su fase faríngea de la deglución a partir de la aplicación de la AC. La organización de la revisión establece la búsqueda de artículos científicos en la utilización de la AC en la evaluación clínica de la deglución en sujetos pediátricos y diagnosticados con Parálisis Cerebral. La información encontrada muestra cómo en ausencia de procesos instrumentales de evaluación deglutoria, la AC aporta como beneficio la accesibilidad del procedimiento, además de características de temporalidad en la secuencia de los sonidos deglutorio, sin ningún tipo de factor adverso para su realización. Es por ello que la auscultación es un recurso importante en la evaluación clínica y se puede establecer como un primer paso en el análisis de los aspectos fisiológicos de la fase faríngea de la deglución, pone a la auscultación en una posición privilegiada, pero que debe ser estandarizada por los estudiosos y teóricos del tema.

In the clinical care, the speech language pathologist has evaluative resources to describe the biomechanics of swallowing; one of the resources used is Cervical Auscultation (CA). (Dudik et al., 2016) Taking into account the description of the importance of the timely and effective intervention of the swallowing processes in children with cerebral palsy, it is considered necessary to solve relevant aspects around the relationship of the clinical characteristics of these children in their swallowing process and the records of the spectrographic profile in their pharyngeal phase of swallowing from the application of CA. In the absence of instrumental swallowing evaluation processes, CA provides the accessibility of the procedure as a benefit, in addition to temporality characteristics in the sequence of swallowing sounds, without any type of adverse factor for its performance. The CA is an important resource in clinical evaluation, it establishes a first step in the physiological analysis of swallowing with the physiological aspects of the pharyngeal phase. This puts auscultation in a privileged position, but it must be standardized by cientifics and theorists on the subject.

Profissionais com formação lato sensu (54,3%) e com mais de uma década de profissão (58,1%) apresentaram maior adequação na interpretação do resultado positivo do BDT. Conclusão O presente estudo reforça o importante papel da formação especializada em disfagia e das práticas de educação continuada em saúde, na determinação da atuação fonoaudiológica clínica de excelência, principalmente com pacientes traqueostomizados pós intubação e com risco de broncoaspiração.

ABSTRACT Purpose To characterize the professional profile of Speech Pathologists working in health services in Brazil and to verify if the time length of professional practice, specialized formation and experience in dysphagia contribute to the more adequate interpretation and application of the Blue Dye Test (BDT). Methods Through social medias and class entities, speech pathologists from all over Brazil were contacted by e-mail, that provided them a link from which they could access the online quiz, containing questions about the professional profile and the application of the BDT. The responses were categorized dichotomously according to the most robust scientific researches on the BDT and were compared statistically according to time length of professional practice, specialized formation and experience in dysphagia. Results 145 speech pathologists participated, 91.7% of them females. Most work in hospitals, have 11 to 15 years of profession (27.6%), and working from 1 to 5 years in the area of dysphagia (32.4%). Professionals with lato sensu training (54.3%) and with more than a decade of profession (58.1%) showed greater adequacy in interpreting the positive result of BDT. Conclusion The present study reinforces the important role of specialized training in dysphagia in addition to continuing health educational practices in determining the excellence of clinical speech therapy, especially with tracheostomized patients after intubation and at risk of bronchoaspiration.

Respuesta del score RIPASA versus el histopatológico como predictor diagnóstico de apendicitis aguda en el Hospital Vicente Corral Moscoso año 2018 / Response of the RIPASA score versus the histopathology as a diagnostic predictor of acute appendicitis at the Vicente Corral Moscoso Hospital in 2018

Antecedentes: la Apendicitis Aguda (A.A) es una urgencia quirúrgica que requiere un diagnóstico y tratamiento oportuno. Muchas veces puede ser un gran reto para el cirujano por su relación con otras patologías, de allí la importancia de precisar su diagnóstico. Objetivo: validar la precisión diagnóstica del score RIPASA en apendicitis aguda comparándolo con el examen histopatológico. Metodología: se realizó un estudio de validación de pruebas diagnósticas con la información de 300 historias clínicas de pacientes apendicectomizados, atendidos en el Hospital Vicente Corral Moscoso durante el año 2018. Se evaluó mediante el score RIPASA al ingreso y se comparó con los resultados de histopatología como prueba gold standar. Se calculó la sensibilidad, especificidad, valor predictivo positivo, valor predictivo negativo, además se obtuvo Odds Ratio con su IC al 95% para establecer la validez predictiva de esta escala. Resultados: la media de edad fue de 32 años ± 13,7 (DS), más de la mitad fueron: sexo femenino 52%, área urbana 74.7% y bachillerato 62.7%, predominó la etnia mestiza 99.7%. Hubo una asociación de riesgo entre una alta probabilidad de apendicitis según el score RIPASA con A.A (OR 96,36; IC95%: 16,03­578,68; p= 0,000). El score RIPASA tiene una sensibilidad de 98.97%, especificidad 50.0%, VPP 98.63%, VPN 57,14%, RVP 1.98% Y RVN 0.2%. Conclusiones: RIPASA tiene alta probabilidad para detectar a personas con apendicitis aguda, pero no así a las sanas, por lo cual se requiere continuar con más estudios para establecer tal validez

Background: Acute Appendicitis (A.A) is a surgical emergency that requires timely diagnosis and treatment. Many times it can be a great challenge for the surgeon because of its relationship with other pathologies, hence the importance of specifying its diagnosis. Objective: To validate the diagnostic accuracy of the RIPASA score in acute appendicitis by comparing it with the histopathological examination. Methodology: A study of validation of diagnostic tests was carried out with the information of 300 medical records of appendectomized patients, treated at the Vicente Corral Moscoso Hospital during 2018. It was evaluated by means of the RIPASA score at admission and compared with the histopathology results. as gold standard test. Sensitivity, specificity, positive predictive value, negative predictive value were calculated, in addition Odds Ratio was obtained with its 95% CI to establish the predictive validity of this scale. Results: The mean age was 32 years ± 13.7 (SD), more than half were: female 52%, urban area 74.7% and high school 62.7%, mixed race ethnicity predominated 99.7%. There was a risk association between a high probability of appendicitis according to the RIPASA score with A.A (OR 96.36; 95% CI: 16.03­578.68; p = 0.000). The RIPASA score has a sensitivity of 98.97%, specificity 50.0%, PPV 98.63%, NPV 57.14%, RVP 1.8% and RVN 0.2% Conclusions: RIPASA has a high probability of detecting people with acute appendicitis, but not healthy ones, so it is necessary to continue with more studies to find such validity

Recommendations from the Brazilian society of rheumatology for the diagnosis of Sjögren's syndrome (Part I): glandular manifestations (systematic review)

Abstract Background: Primary Sjögren's syndrome (pSS) is a systemic immune-mediated disease whose main characteristic is exocrine gland inflammation and, subsequent reduction in tear and saliva production. A delayed diagnosis is common due to the nonspecific clinical manifestations of disease. The aim of the present study was to develop recommendations for the diagnosis of glandular manifestations of pSS based on evidence and expert opinion. Main body of the abstract: We conducted a systematic literature review to retrieve the best evidence available on the accuracy of diagnostic tests for pSS. We also held two in-person meetings with experts (rheumatologists, pathologists, ophthalmologists and dentists) to establish their level of agreement using the Delphi method. Ultimately, we generated 18 recommendations that aim to facilitate the diagnosis of the glandular manifestations of pSS. Conclusion: The diagnosis of glandular manifestations of pSS is complex and multidisciplinary. It requires specific knowledge in the field of ophthalmology, immunology, pathology and imaging, making it compulsory for the rheumatologist to work with professionals from these different areas in order to improve accuracy and early diagnosis. Glandular dysfunction tests, ANA, RF, Anti-Ro, protein electrophoresis, urinalysis, blood count, C-Reactive protein, complement, testing for syphilis and viruses (HCV, HIV) and SGUS should be investigated when dryness or systemic manifestation are present. Minor salivary gland biopsy is recommended for all anti-Ro negative or incomplete criteria cases.

Artificial intelligence system of faster region-based convolutional neural network surpassing senior radiologists in evaluation of metastatic lymph nodes of rectal cancer / 中华医学杂志(英文版)

BACKGROUND@#An artificial intelligence system of Faster Region-based Convolutional Neural Network (Faster R-CNN) is newly developed for the diagnosis of metastatic lymph node (LN) in rectal cancer patients. The primary objective of this study was to comprehensively verify its accuracy in clinical use.@*METHODS@#Four hundred fourteen patients with rectal cancer discharged between January 2013 and March 2015 were collected from 6 clinical centers, and the magnetic resonance imaging data for pelvic metastatic LNs of each patient was identified by Faster R-CNN. Faster R-CNN based diagnoses were compared with radiologist based diagnoses and pathologist based diagnoses for methodological verification, using correlation analyses and consistency check. For clinical verification, the patients were retrospectively followed up by telephone for 36 months, with post-operative recurrence of rectal cancer as a clinical outcome; recurrence-free survivals of the patients were compared among different diagnostic groups, by methods of Kaplan-Meier and Cox hazards regression model.@*RESULTS@#Significant correlations were observed between any 2 factors among the numbers of metastatic LNs separately diagnosed by radiologists, Faster R-CNN and pathologists, as evidenced by rradiologist-Faster R-CNN of 0.912, rPathologist-radiologist of 0.134, and rPathologist-Faster R-CNN of 0.448 respectively. The value of kappa coefficient in N staging between Faster R-CNN and pathologists was 0.573, and this value between radiologists and pathologists was 0.473. The 3 groups of Faster R-CNN, radiologists and pathologists showed no significant differences in the recurrence-free survival time for stage N0 and N1 patients, but significant differences were found for stage N2 patients.@*CONCLUSION@#Faster R-CNN surpasses radiologists in the evaluation of pelvic metastatic LNs of rectal cancer, but is not on par with pathologists.@*TRIAL REGISTRATION@#www.chictr.org.cn (No. ChiCTR-DDD-17013842).

Histologic review of melanomas by pathologists trained in melanocytic lesions may change therapeutic approach in up to 41 9% of cases

Abstract: Melanoma Guidelines of the Brazilian Dermatology Society recommend histologic review by pathologists trained in melanocytic lesions whenever possible. Out of 145 melanoma cases identified at a private clinic in São Paulo/Brazil, 31 that had been submited to histologic review were studied to evaluate whether revision had led to change in therapeutic approach.. Differences in original/reviewed reports were found in 58.1% (n=18) of the reports, leading to changes in therapeutic approach in 41.9% (n=13). Change in diagnosis was observed in 6 out of 31 (19,3%) cases. These findings suggest that second opinion by pathologists trained in melanocytic lesions is likely to show significant differences from the original report.

Tuberculosis extrapulmonar en paciente inmunocompetente / Extrapulmonary tuberculosis in immunocompetent patient

La tuberculosis extrapulmonar se define como la infección ocasionada por Mycobacterium tuberculosis a tejidos y órganos fuera del parénquima pulmonar, aproximadamente el 1-3 % del total de los casos de TB son extrapulmonares y de estos el 11-16 % afectan al abdomen; 10 al 15 % en los no infectados por el VIH y hasta en 70 % en los infectados. El presente reporte es acerca de una paciente de 34 años, sexo femenino, heterosexual, que no refirió conductas sexuales de riesgo, misma que solicitó valoración por emergencias del hospital general del norte de Guayaquil Los Ceibos (HGNG-C), refiriendo manifestaciones clínicas de 1 semana de evolución aproximadamente, tales como: náusea, vómitos, deposiciones líquidas en varias ocasiones, sin mejoría a pesar de tratamiento médico previo, que se complica con la aparición de dolor abdominal severo, por el cual se decidió efectuar apendicetomía de emergencia; en los resultados anatomopatológicos se detectaron estructuras granulomatosas, estableciéndose el diagnóstico de tuberculosis extrapulmonar.

Extrapulmonary tuberculosis is defined as the infection caused by Mycobacterium tuberculosis to tissues and organs outside the lung parenchyma, approximately 1-3 % of the total TB cases are extrapulmonary and of these 11-16 % affect the abdomen; 10 to 15 % in those not infected by HIV and up to 70 % in those infected. The present report is about a 34-year-old female,heterosexual, who did not report risky sexual behavior, who requested emergency assessment from the general hospital in the north of Guayaquil Los Ceibos (HGNG-C), referring to manifestations clinics of 1 week of evolution, such as: nausea, vomiting, liquid stools on several occasions, without improvement despite previous medical treatment, which is complicated by the appearance of severe abdominal pain, for which it was decided to perform emergency appendectomy ; In the anatomopathological results, granulomatous structures were detected, establishing the diagnosis of extrapulmonary tuberculosis.

José Verocay, el "patólogo de Praga" (1876-1927) / José Verocay, "Prague's pathologist" (1876-1927) / José Verocay, "o patologista de Praga" (1876-1927)

José Verocay (Paysandú, 1876-Teplitz Bohemia, 1927) fue un médico anatomopatólogo uruguayo de reconocimiento internacional, quién en 1910 describió, por primera vez, las estructuras que más tarde fueran nombradas como "cuerpos de Verocay", consideradas de fundamental importancia en el diagnóstico de Schwannoma (a pesar de no ser exclusivos del mismo). Su formación personal y científica se desarrolló en Europa en la Universidad Carolina de Praga, culminando con el máximo cargo académico posible de obtener en sus condiciones, el Privat Dozent (1910). Luego de su exilio, en 1919 regresa a Uruguay donde obtiene el cargo de Profesor de Anatomía Patológica en la Escuela de Odontología (1925). Ese mismo año aspira al cargo de Profesor de Anatomía Patológica de la Facultad de Medicina, cargo al cuál no accede generando una gran controversia entre médicos y estudiantes. En 1927 debido al deterioro de su salud, decide viajar a Viena en pos de su cura, en Uruguay se le realiza un Homenaje público a iniciativa de los estudiantes de odontología de la época, realizado en el Salón de Actos de la Facultad de Medicina, en donde por aquellos años se formaban los futuros odontólogos. Allí los propios estudiantes lo proclaman: "Maestro insigne de la generación médica actual", "Profesor por derecho propio de la Juventud médica". Fallece en Eichwald, distrito de Teplitz, Bohemia, en 1927, con 51 años de edad. Este artículo busca ser un breve repaso de su trayectoria académica en el Uruguay y en el mundo.

José Verocay (Paysandú 1876-Teplitz Bohemia 1927) was an Uruguayan pathologist of international recognition. In 1910 he described for the first time the structures that were later named "Verocay's bodies", considered of fundamental importance in the diagnosis of schwannoma (also present in other pathologies). His personal and scientific training was carried out in Europe at the University Carolina in Prague, culminating with the maximum academic position, Privat Dozent (1910). After his exile, in 1919, he returned to Uruguay where he obtained the position of Professor of Pathological Anatomy at the School of Dentistry (1925). That year he aspired to the position of Professor of Pathological Anatomy of the Faculty of Medicine, a position which he did not get, generating a great controversy between doctors and students. In 1927 due to the deterioration of his health, he decided to travel to Vienna looking after his cure. In Uruguay a public tribute was made by the initiative of the students of dentistry, it took place in the Hall of Acts of the Faculty of Medicine, where, in those years, the future odontologists were educated. There, the students themselves proclaimed him "Master of the current medical generation", "Professor in his own right Medical Youth". He passed away in Eichwald, Teplitz district in Bohemia, in 1927 at the age of 51. This article seeks to be a brief review of his academic career in Uruguay and in the world.
