Abstract Introduction: cystic fibrosis newborn screening must enable its earlier diagnosis, which may enhance outcomes. This study was a series case of delayed-diagnosis children submitted to cystic fibrosis newborn screening. Description: fourteen children were included; eight (57.1%) were due to false-negative screening, while six (42.9%) were due to processing errors. Two samples collected after 30 days of life were incorrectly classified as negative, and four infants with a positive test could not be located due to screening processing errors. Cystic fibrosis diagnosis was confirmed at a median (IQR) age of 5.3 (4.2-7.4) months. Poor nutritional status was the most prevalent clinical sign at diagnosis, being present in 78.6% of infants. The mean (SD) weight-for-length and length-for-age Z-scores were -3.46 (0.84) and -3.99 (1.16), respectively. Half of the children had Pseudo-Bartter syndrome, and 42.9% had breathing difficulties. Twelve children (85.7%) required hospitalization, with a median (IQR) length of stay of 17.0 (11.5-26.5) days. Discussion: newborn screening had some faults, from incorrect collections to inefficient active search. Early identification of these children in which screening was unsatisfactory is essential, emphasizing the importance and efforts to not miss them. In the case of a failed test, healthcare professionals must be prepared to recognize the main symptoms and signs of the disease.

Resumo Introdução: a triagem neonatal para fibrose cística deve contribuir para diagnóstico precoce e melhor prognóstico da doença. O estudo é uma série de casos com lactentes submetidos à triagem, porém com diagnóstico tardio da doença. Descrição: quatorze crianças foram incluídas; oito (57,1%) com triagem falso-negativo e seis (42,9%) com erros processuais na triagem neonatal. Duas amostras foram coletadas tardiamente, sendo incorretamente classificadas como negativas e quatro lactentes com triagem positiva não foram localizados, por erros na busca ativa. Confirmou-se o diagnóstico da fibrose cística com idade mediana (IIQ) de 5,3 (4,2-7,4) meses. O Comprometimento nutricional precoce foi o sinal clínico mais prevalente ao diagnóstico, presente em 78,6% das crianças. Os Z escores médios (SD) do peso para altura e altura para idade foram -3,46 (0,84) e -3,99 (1,16), respectivamente. Metade das crianças teve síndrome de Pseudo-Bartter e 42,9% dificuldade respiratória. Doze crianças (85,7%) precisaram hospitalização com tempo mediano de permanência de 17 dias. Discussão: a triagem neonatal para fibrose cística apresentou falhas, desde testes falso-negativos, coletas incorretas, até problemas com a busca ativa. Entretanto, o diagnóstico ágil é essencial e os profissionais de saúde devem reconhecer os sintomas e sinais precoces da doença, mesmo quando a triagem neonatal não for satisfatória.

Pneumoconiosis is characterized by chronic lung inflammation and fibrosis, and inflammation can promote pulmonary fibrosis, which in turn leads to pneumoconiosis. When a large shadow with a long diameter of not less than 2 cm and a short diameter of not less than 1 cm appears in the lung, it can be classified as stage Ⅲ pneumoconiosis. This paper reports a case of stage Ⅲ pneumoconiosis with a large shadow in the upper right lung accompanied by burr-like changes misdiagnosed as lung cancer by CT examination.When the large shadow lesions in patients with pneumoconiosis and lung cancer are difficult to distinguish on CT, an additional MRI examination, particularly T(2)W imaging sequence is useful sequence for identifying the two.

Objective: To investigate the misdiagnosis of area postrema syndrome (APS) manifesting as intractable nausea, vomiting and hiccups in neuromyelitis optic spectrum disease (NMOSD) and reduce the risk of misdiagnosis. Methods: We retrospectively analyzed data from NMOSD patients attending the Department of Neurology at the First Medical Center of PLA General Hospital between January 2019 and July 2021. SPSS25.0 was then used to analyze the manifestations, misdiagnosis, and mistreatment of APS. Results: A total of 207 patients with NMOSD were included, including 21 males and 186 females. The mean age of onset was 39±15 years (range: 5-72 years). The proportion of patients who were positive for serum aquaporin 4 antibody was 82.6% (171/207). In total, 35.7% (74/207) of the NMOSD patients experienced APS during the disease course; of these patients, 70.3% (52/74) had APS as the first symptom and 29.7% (22/74) had APS as a secondary symptom. The misdiagnosis rates for these conditions were 90.4% (47/52) and 50.0% (11/22), respectively. As the first symptom, 19.2% (10/52) of patients during APS presented only with intractable nausea, vomiting and hiccups; 80.8% (42/52) of patients experienced other neurological symptoms. The Departments of Gastroenterology and General Medicine were the departments that most frequently made the first diagnosis of APS, accounting for 54.1% and 17.6% of patients, respectively. The most common misdiagnoses related to diseases of the digestive system and the median duration of misdiagnosis was 37 days. Conclusions: APS is a common symptom of NMOSD and is associated with a high rate of misdiagnosis. Other concomitant symptoms often occur with APS. Gaining an increased awareness of this disease/syndrome, obtaining a detailed patient history, and performing physical examinations are essential if we are to reduce and avoid misdiagnosis.

RESUMO Objetivo Estudar o processo de diagnóstico audiológico de lactentes que falharam na Triagem Auditiva Neonatal Universal (TANU). Métodos Análise dos prontuários de 51 lactentes que falharam na TANU nas maternidades do munícipio e que foram encaminhados a um centro de referência em saúde auditiva para diagnóstico audiológico, entre janeiro e junho de 2021. Foram identificados os lactentes que finalizaram o diagnóstico, aqueles que não compareceram ao agendamento para exames ou evadiram durante o processo. Tentativas de contato foram realizadas com os responsáveis pelos lactentes que evadiram, para identificar o motivo da evasão. Resultados O comparecimento ao diagnóstico ficou em 75%, com evasões entre o encaminhamento da maternidade para o centro de referência, bem como durante o processo de diagnóstico. Cinquenta por cento dos sujeitos concluíram as avaliações audiológicas até os 3 meses de vida. A tentativa de contato foi bem-sucedida com os responsáveis pelos lactentes que evadiram, sendo os motivos mais frequentes: adoecimento do lactente, distância entre a moradia e o centro de referência, horário de trabalho dos pais. Conclusão Na etapa de diagnóstico, o índice de comparecimento e o tempo de conclusão até o terceiro mês de vida da criança ficaram abaixo dos índices recomendados, diminuindo a efetividade do Programa de Triagem Auditiva Neonatal Universal (PTANU). A busca ativa por contato telefônico e uso de aplicativo de mensagem telefônico foi importante para reduzir a evasão em 76%. Outras ferramentas que aprimorem o processo para um diagnóstico não prolongado, evitando evasões, necessitam ser estudadas.

ABSTRACT Purpose To study the process of hearing assessment in infants who were referred by professionals responsible for Universal Newborn Hearing Screening (UNHS). Methods Analysis of the medical records of 51 infants referred by maternity hospitals where UNHS was performed and were referred to a Hearing Health Center, between January and June 2021. Infants who completed hearing assessment, who never attended the appointments, or were lost during the diagnostic process were identified. Attempts were made to contact infants' guardians in order to understand the reason for missing the appointments. Results The attendance to the diagnosis was 75%. Fifty percent of the infants completed hearing assessment as recommended, up to 3 months of life. The attempt to contact parents who missed the appointments was successful, and the most frequent reasons are: the infant was ill on the day of scheduled appointment, distance from home to the hearing health center, parents' working hours. Conclusion For the diagnostic stage, the attendance rate and the age for completing hearing assessment were below the recommended. The active search for telephone contact and use of phone messaging application was important to reduce evasion by seventy-six percent. Tools that optimize the diagnostic process with less infants missing still must be studied.

Background. Patient safety research is scarce in developing countries. Estimates of patient harm due to healthcare processes in resource-poor settings are thought to be greater than those in developed countries. Ideally, errors in healthcare should be seen as opportunities to improve the future quality of care. Objective. This study aimed to investigate patient safety culture within high-risk units of a tertiary hospital in South Africa. Methods. A quantitative, descriptive, cross-sectional methodology, using a survey questionnaire that measured 10 safety dimensions and one outcome measure among clinical and nursing staff, was employed. Results. Two hundred participants completed the survey questionnaire. Areas of strength identified by the participants included organizational learning (91.09%), staff attitudes (88.83%), and perceptions of patient safety (76.65%). Dimensions that have potential for improvement included awareness and training (74.04%), litigation (73.53%), feedback and communication about errors (70.77%), non-punitive response to error reporting (51.01%), size and tertiary level of the hospital (53.76%), and infrastructure and resources (58.07%). The only dimension identified as weak was teamwork and staffing (43.72%). In terms of the patient safety grade, respondents graded their own units highly but graded the hospital as a whole as having a poor patient safety grade. Conclusion. There are still significant gaps in the quality of care provided at this tertiary hospital. The current patient safety culture is perceived as punitive in nature with regard to reporting adverse events. It is advised that targeted patient safety improvements be made, followed by further investigation

Na prática clínica da dermatologia não é incomum nos depararmos com situações desafiadoras, de difícil caracterização e que podem nos induzir ao erro diagnóstico. Quadros cutâneos com apresentações semelhantes entre si estão aqui inclusas e, neste caso, é de suma importância a atuação do médico dermatologista de forma a unir as informações da anamnese, exame físico e exames complementares, a fim de excluir condições de pior prognóstico e que requerem atuação mais agressiva de outras condições benignas e/ou com menor impacto negativo. Apresentamos abaixo uma dessas situações de desafio diagnóstico em que uma lesão cutânea secundária à osteomielite crônica foi inicialmente atribuída à causa inflamatória ou neoplásica (AU)

In the clinical practice of Dermatology, it is not uncommon to encounter challenging situations that are difficult to characterize and may lead to misdiagnosis. Skin conditions with similar presentations are included here and, in this case, it is of utmost importance that the dermatologist combines information from the medical history, physical examination and complementary tests in order to exclude conditions with worse prognosis and that require more aggressive action than other benign conditions and/or with less negative impac (AU)

El suicidio ­o las autolesiones como su antecesor mortífero­ no suelen ser más que una pantalla a un dolor imposible de ser procesado por el sujeto que padece. Las coordenadas que lo atraviesan se amplían, convergen y torsionan en una espiral sin fin cuando ya no quedan recursos para encontrar una salida vital. El proyecto de vida pareciera impensable, en especial, cuando las múltiples versiones de lo ominoso se hacen presentes. Si además el tiempo etario donde aparecen coincide con un tiempo crucial ­adolescencia, jóvenes, adultos mayores­ suele requerirse algún modo de apuntalamiento al Yo en crisis. En este episodio de New Amsterdam vemos como el desinvestimiento subjetivo que produce la invisibilidad del sujeto para los objetos externos diferenciados madre familia (Aulagnier,2004) hacen a una joven intentar construir su identidad bajo un tiempo extremo de angustia

Suicide ­or self-harm like its deadly predecessor­ are usually nothing more than a screen for a pain impossible to be processed by the subject who suffers. The coordinates that pass through it expand, converge and twist in an endless spiral when there are no more resources left to find a vital exit. The life project seems unthinkable, especially when the multiple versions of the ominous are present. If, in addition, the age period in which they appear coincides with a crucial time ­ adolescence, youth, older adults ­ some form of propping up the Self in crisis is usually required. In this episode of New Amsterdam we see how the subjective disinvestment that produces the invisibility of the subject for the differentiated external objects mother-family (Aulagnier, 2004) makes a young woman try to build her identity under an extreme time of anguish

INTRODUCCIÓN: El nuevo coronavirus ha continuado propagándose por todo el mundo donde existen otras enfermedades endémicas que han sido una carga para la salud pública durante muchos años. Como cualquier infección, se habría esperado encontrar en coinfección con algunas de éstas. Específicamente, los países tropicales y subtropicales han venido manejando la carga del dengue a medida que aumentan los picos con períodos de tiempo más cortos. OBJETIVO: Resumir la evidencia que existe en la coinfección relacionada con el SARS-CoV-2 y el virus del dengue. METODOLOGÍA: Se realizó una revisión narrativa en bases de datos sobre reportes de coinfección y diagnóstico erróneo de SARS-CoV-2 y el dengue dado que la temporada de lluvias cada año aumenta la prevalencia de infecciones virales en países endémicos. Informes recientes incluso han descrito casos positivos en uno de estas infecciones que luego resultaron en falso positivo. Una prueba positiva para COVID-19 o fiebre del dengue en áreas endémicas no debe excluir la otra infección. CONCLUSIÓN: A partir de ahora, estos dos deberían ser considerados como un diagnóstico diferencial y esto debe generar preocupación de salud pública por su coinfección en países endémicos para reforzar la promoción y prevención a las comunidades y mitigar estas enfermedades.

BACKGROUND: Novel coronavirus has continued to spread throughout the world where there are other endemic diseases that have been a burden to public health for many years. As any infection, it was expected there could be coinfection between these. Tropical and subtropical countries are currently managing with dengue as peaks increase with shorter periods of time. AIM: To summarize the evidence that exists in the co-infection related to SARS-CoV-2 and the dengue virus. METHOD: We conducted a narrative review in data bases about reports of coinfection and misdiagnosis of SARS-CoV-2 and dengue virus given the fact that rainy season every year increase the prevalence of viral infections in endemic countries. Recent reports have even described positive cases in one of these infections that later resulted in false positive. A positive test for COVID-19 or dengue fever in endemic areas should not exclude the other infection. CONCLUSION: From now on, these two should be considered as a differential diagnosis and this should raise public health concern for COVID-19 and dengue coinfection in endemic countries to reinforce promotion and prevention to communities to prevent these diseases.

Background and objectives: Leprosy is an infectious disease in which early diagnosis is a decisive factor to prevent disability and disabilities. This study sought to analyze the panorama of leprosy between 2016 and 2021 in the state of Rio Grande do Sul and unveil the importance of medical education in the context of Neglected Tropical Diseases during the Sars-CoV-2 pandemic. Methods: Cross-sectional study using the State Center database of Health Surveillance of Rio Grande do Sul. In the data collection, were included leprosy data of individuals residents in the state of Rio Grande do Sul (RS), in the 2016 period 2021. The variables analyzed were confirmed leprosy cases, notified cases, the number of cases in terms of operational classifications of leprosy, the therapeutic scheme, and the number of cases according to the degrees of physical disability. Results: Over this period, 725 cases were confirmed as leprosy, 70% in the years 2016, 2017 and 2018. Of the total number of cases, 88% were Multibacillary form of the disease, 50% had some degree of disability at diagnosis time and 80% underwent the standard treatment regimen. Conclusion: There is a delay in leprosy diagnosis, and there is underdiagnosis of the disease in the state of Rio Grande do Sul: which highlights the need to reaffirm educational practices on mycobacteriosis.(AU)

Hipertensão arterial leve é uma condição assintomática caracterizada por pressão arterial entre 14/9 e 16/10 mmHG e baixo risco de problemas cardiovasculares. É a condição de aproximadamente dois terços das pessoas diagnosticadas com alguma forma de hipertensão. A melhor evidência disponível não apoia o tratamento farmacológico desse grupo para a redução de mortalidade cardiovascular. Além disso, a sobredetecção de hipertensão ocorre e essa prática é apoiada por campanhas de conscientização ao público, rastreamento, acesso fácil ao teste e má prática clínica, que aumentam potencialmente o sobrediagnóstico. Poucas pesquisas qualitativas orientadas para os pacientes mostram que diagnosticar hipertensão pode ter também consequências negativas. Diante disso, são necessárias evidências sobre o potencial de efeitos psicossociais não esperados no diagnóstico de hipertensão. Objetivo: Investigar se o diagnóstico de pessoas de baixo risco com hipertensão leve tem consequências psicossociais indesejadas. Métodos: Onze entrevistas semiestruturadas e quatro grupos focais foram conduzidos em São Paulo, Brasil, com pessoas que relataram hipertensão arterial leve, sem comorbidades, com ou sem uso de medicação. Informantes foram selecionados da população geral por meio de lista de pacientes de unidades de atenção primária e também recrutados por redes sociais. Os participantes tiveram variedade em termos de sexo, idade, nível educacional, cor de pele e tempo de diagnóstico. Os dados foram submetidos à análise qualitativa de conteúdo temático por três dos autores independentemente, o que foi seguido de discussões para gerar categorias e temas. Resultados: os informantes confirmaram que o diagnóstico de hipertensão foi tomado como um rótulo para reações psicossomáticas ao estresse, medicalizou situações difíceis e causadoras de estresse, nomeando-as como doença, e foi um marco biográfico. Nós observamos consequências não intencionais do diagnóstico em uma ampla gama de dimensões psicossociais, por exemplo, medo de morte, doença e envelhecimento; pressão e controle por parte de pessoas próximas; e culpa, vergonha e ansiedade em relação ao trabalho e ao lazer. Apesar das diferentes características dos informantes, todos compartilharam histórias e sentimentos semelhantes relacionados ao rótulo. Conclusão: O diagnóstico de hipertensão é um evento significativo que afeta o dia a dia. A maior parte do impacto é considerada como consequências psicossocias negativas; porém, às vezes, o impacto pode ser ambíguo ou mesmo positivo. Os modelos explanatórios das pessoas são elementos-chave para entender e abordar as consequências psicossociais do diagnóstico, e profissionais de saúde e formuladores de políticas públicas devem estar atentos a esses potenciais consequências negativas na avaliação de risco/benefício das estratégias de diagnóstico desses casos.

Introduction: Mild hypertension is a common asymptomatic condition present in people at low risk of future cardiovascular events. These people represent approximately two-thirds of those diagnosed with hypertension. The best available evidence does not support pharmacological treatment for mild hypertension to reduce cardiovascular mortality. Additionally, overdetection of hypertension also occurs, and this practice is supported by public awareness campaigns, screening, easy access to testing, and poor clinical practice, enhancing the overdiagnosis potential. Moreover, sparse qualitative patient-oriented evidence that diagnosing hypertension has harmful consequences is observed. Therefore, evidence regarding the potential for unintended psychosocial effects of diagnosing mild hypertension is required. Objective: The aim of this study was to investigate if diagnosing low-risk people with mild hypertension has unintended psychosocial consequences. Methods: Eleven semi-structured single interviews and four focus groups were conducted in São Paulo, Brazil, among people diagnosed with mild hypertension without comorbidities. Informants were selected among the general population from a list of patients, a primary healthcare clinic, or a social network. The informants had a broad range of characteristics, including sex, age, education level, race/skin colour, and time from diagnosis. Data were subjected to qualitative thematic content analysis by three of the authors independently, followed by discussions, to generate categories and themes. Results: The informants confirmed that the hypertension diagnosis was a label for psychosomatic reactions to stress, medicalised illness experiences, and set a biographical milestone. We observed unintended consequences of the diagnosis in a broad range of psychosocial dimensions, for example, fear of death, disabilities, or ageing; pressure and control from significant others; and guilt, shame, and anxiety regarding work and leisure. Although informants had a broad range of characteristics, they shared similar stories, understandings, and labelling effects of the diagnosis. Conclusion: The diagnosis of hypertension is a significant event and affects daily life. Most of the impact is regarded as negative psychosocial consequences or harm; however, sometimes the impact might be ambiguous. Patients' explanatory models are key elements in understanding and changing the psychosocial consequences of the diagnosis, and healthcare providers must be aware of explanatory models and psychosocial consequences when evaluating blood pressure elevations.

Introducción: La hipertensión leve es una condición asintomática común presente en personas con bajo riesgo de eventos cardiovasculares futuros. Estas personas representan aproximadamente dos tercios de las personas diagnosticadas con hipertensión. La mejor evidencia disponible no respalda el tratamiento farmacológico de la hipertensión leve para reducir la mortalidad cardiovascular. Además, también se produce la sobre detección de hipertensión, y esta práctica está respaldada por campañas de concienciación pública, cribados, fácil acceso a las pruebas y mala práctica clínica, lo que aumenta el potencial de sobrediagnóstico. Además, se observa escasa evidencia cualitativa orientada al paciente de que el diagnóstico de hipertensión tiene consecuencias nocivas. Por lo tanto, se requiere evidencia con respecto al potencial de efectos psicosociales no deseados del diagnóstico de hipertensión leve. Objetivo: investigar si el diagnóstico de personas de bajo riesgo con hipertensión leve tiene consecuencias psicosociales no deseadas. Métodos: Se realizaron once entrevistas semiestructuradas y cuatro grupos focales en São Paulo, Brasil, entre personas diagnosticadas con hipertensión leve sin comorbilidades. Los informantes fueron seleccionados entre la población general de una lista de pacientes, de una clínica de atención primaria o de una red social. Los informantes tenían una amplia gama de características que incluían sexo, edad, nivel de educación, origen étnico, color de piel y tiempo desde el diagnóstico. Los datos fueron sometidos a un análisis de contenido temático cualitativo por tres de los autores de forma independiente, seguido de discusiones, para generar categorías y temas. Resultados: Los informantes confirmaron que el diagnóstico de hipertensión era una etiqueta para reacciones psicosomáticas al estrés, experiencias de enfermedad medicalizadas y marcaba un hito biográfico. Observamos consecuencias no deseadas del diagnóstico en una amplia gama de dimensiones psicosociales, por ejemplo, miedo a la muerte, discapacidades o envejecimiento; presión y control de otras personas significativas y culpa, vergüenza y ansiedad en relación con el trabajo y el ocio. Aunque los informantes tenían una amplia gama de características, compartían histórias, entendimientos y efectos de etiquetado similares del diagnóstico. Conclusión: el diagnóstico de hipertensión es un evento significativo y afecta la vida diaria. La mayor parte del impacto se considera como consecuencias o daños psicosociales negativos; sin embargo, a veces el impacto puede ser ambiguo. Los modelos explicativos de los pacientes son elementos clave para comprender y cambiar las consecuencias psicosociales del diagnóstico, y los proveedores de atención médica deben conocer los modelos explicativos y las consecuencias psicosociales al evaluar las elevaciones de la presión arterial, comunicarse y tratar.

Objetivo: descrever e reclassificar os diagnósticos de outras neoplasias de exames histopatológicos do colo do útero registrados no Sistema de Informação do Câncer (Siscan), Brasil, 2013-2020. Métodos: estudo descritivo dos diagnósticos compilados no campo "outras neoplasias malignas" do Siscan; os diagnósticos foram avaliados por patologista e reclassificados nas categorias existentes no formulário; foram calculadas frequências absolutas e relativas dos diagnósticos registrados incorretamente. Resultados: o diagnóstico "outras neoplasias malignas" representou 2,4% (n = 5.778) dos diagnósticos, dos quais 67,4% poderiam ser registrados em categorias existentes, 8,9% eram efetivamente outros tipos de neoplasias malignas, e 24,5% apresentavam resultados não compatíveis com outras neoplasias, como achados benignos ou fora do colo do útero, não disponíveis nos campos existentes. Conclusão: o campo "outras neoplasias malignas" é frequentemente utilizado de maneira inadequada, no Siscan; constata-se a necessidade de capacitar os profissionais para o adequado uso dos campos do sistema e incluir novas categorias diagnósticas no formulário.

Objetivo: describir y reclasificar los diagnósticos registrados en el campo "otras neoplasias malignas" de exámenes histopatológicos del cuello uterino en el Sistema de Información del Cáncer (Siscan), Brasil, 2013-2020. Métodos: estudio descriptivo del campo "otras neoplasias malignas" en Siscan; estudio descriptivo de las fichas diagnósticas recopiladas en el campo "otras neoplasias malignas" en Siscan entre 2013 y 2020. Resultados: los diagnósticos histopatológicos "otras neoplasias malignas" representaron el 2,4% (n = 5.778) del total, de los cuales el 67,4% se pudo registrar en las categorías existentes, el 8,9% fueron en realidad otros tipos de neoplasias malignas y el 24,5% fueron resultados no compatibles con otras neoplasias y que no estaban incluidas en las opciones existentes. Conclusión: el campo "otras neoplasias malignas" es frecuentemente utilizado de manera inadecuada, en Siscan; existe la necesidad de capacitar a los profesionales para que utilicen correctamente los campos del sistema e incluyan nuevas categorías de diagnóstico en el formulario.

Objective: to describe and reclassify cervical histopathology test result diagnoses recorded as other neoplasms on the Cancer Information System (SISCAN), Brazil, 2013-2020. Methods: this was a descriptive study based on diagnoses input to the "other malign neoplasms" field on the SISCAN; a pathologist assessed the diagnoses and reclassified them based on the categories existing on the standardized record form; absolute and relative frequencies of incorrectly recorded diagnoses were calculated. Results: histopathology test results registered as "other malign neoplasms" accounted for 2.4% (n = 5,778) of all records, 67.4% of which in fact fell into categories already existing on the form, 8.9% were indeed other neoplasms and 24.5% were results not compatible with other neoplasms and were not covered by the form categories, such as benign findings or findings outside the cervix. Conclusion: the "other malignant neoplasms" field is frequently misused on the SISCAN; the analysis highlighted the need to train professionals to use the system properly, as well as the need to include new categories on the form.

Pseudomyogenic hemangioendothelioma (PHE) is a rare angiogenic tumor. Histologically, the morphological characteristics of neoplastic vessels and endothelial differentiation are not obvious, and it is easy to be confused with epithelioid sarcoma, epithelioid hemangioendothelioma and myogenic tumor. PHE usually occurs in arms and legs in young people and has a significant male predominance. The tumor has a predilection for the distal extremities and its typical manifestation is multiple center invasion of a single limb, which can involve all layers of skin and subcutaneous tissues,and is often accompanied by abvious pain. Histologically, PHE is characterized by infiltrative growth of tumor. Most tumor lesions are composed of sheets and loose fascicles of plump spindle or epithelioid cells within a background of variably prominent inflammatory infiltration, which was commonly composed of neutrophils. Some cells may resemble rhabdomyoblasts, and nuclear atypia and mitosis were rare. The tumor cells generally expressed positive cytokeratin (CK), ETS-related gene (ERG), Friend leukemia virus integration 1 (FLI1) and integrase interactor 1(INI1). In some cases, the tumor cells expressed CD31. A case of a young woman was reported in this paper, who presented with a subcutaneous mass with severe pain and was chronologically misdiagnosed with herpes zoster, low-grade malignant fibrous histiocytoma and epithelioid hemangioendothelioma. In this study, the clinical and pathological features, differential diagnosis and the latest progress in therapy of PHE were analyzed based on relevant literature.

Introdução: O manejo da cefaleia nas salas de urgência e emergência deve ser baseada em uma anamnese detalhada para que o diagnóstico e tratamento sejam adequados, entretanto não é o que se encontra nos atendimentos. Objetivo: Avaliar o manejo do atendimento das cefaleias em uma sala de Urgência e Emergência. Métodos: Estudo de corte transversal retrospectivo, realizado através da análise de dados de 1317 prontuários eletrônicos de pacientes com queixa de cefaleia que procuraram o serviço de emergência do Hospital Regional de Barbacena durante o período de 01 de janeiro de 2017 a 30 de junho de 2019. Os diagnósticos relatados nos prontuários foram classificados de acordo com os critérios da Classificação Internacional das Cefaleias (ICHD-3). Os dados foram submetidos à análise estatísticas, pelo teste de qui-quadrado. Considerou-se diferenças estatisticamente significativas aquelas cujo valor p≤0,05. Resultados: Do total de prontuários, três foram excluídos, sendo analisados 1314. Entre os prontuários analisados, 73,21% apresentaram diagnósticos iniciais eram cefaleia, 16,67% migrânea e 10,12% cefaleia do tipo tensão. Já no diagnóstico final, cefaleia correspondeu a 59,67%, migrânea a 17,95% e cefaleia do tipo tensão a 8,52%. Em relação ao tratamento, foi receitado opioides para 43,99% dos pacientes e para o restante foram prescritos medicamentos não opioides. Conclusão: O trabalho sugeriu falha no manejo da cefaleia nas salas de urgência e emergência, provavelmente pela limitação do conhecimento dos profissionais de saúde acerca da dor de cabeça. O que acarretou no grande número de diagnósticos inespecíficos e inadequada abordagem terapêutica.

Introduction: Detailed clinical evaluation should be the basis for the proper management of headaches in emergency rooms, in order to allow adequate diagnosis and treatment. However, this is not usually observed on clinical rounds. Objective: To evaluate the management of headache consultations in an emergency rooms. Methods: This is a cross-section study was performed analyzing data from 1,317 electronic medical records of patients with headache complaints who sought treatment at the Barbacena City Regional Hospital's between January 1, 2017, and June 20, 2019. Medical records were classified according to the International Classification of Headache Disorders (ICHD-3). The data collected were statistically analyzed using chi-square tests. The study considered a p-value≤0.05 to define statistically significant differences. Results: Three medical records were excluded and 1,314 were analyzed. Among the medical records analyzed, 73.21% of initial diagnoses were classified as headache, 16.67% as migraine, and 10.12% as tension-type headache. Headache corresponded to 59.76% of final diagnoses, migraine to 17.95%, and tension-type headache to 8.52%. Regarding the treatment, 43.99% of patients were prescribed opioids for the remaining were prescribed nonopioid medications. Conclusion: The study suggests that the management of headaches is inadequate in emergency rooms, probably due to limited knowledge of health professionals about headache. This resulted in a large number of nonspecific diagnoses and inadequate therapeutic approaches.

ABSTRACT Optical coherence tomography is often used for detection of glaucoma as well as to monitor progression. This paper reviews the most common types of artifacts on the optical coherence tomography report that may be confused with glaucomatous damage. We mainly focus on anatomy-related artifacts in which the retinal layer segmentation and thickness measurements are correct. In such cases, the probability maps (also known as deviation maps) show abnormal (red and yellow) regions, which may mislead the clinician to assume disease is present. This is due to the anatomic variability of the individual, and the normative database must be taken into account.

RESUMO A tomografia de coerência óptica é frequentemente usada para detectar glaucoma, bem como para monitorar a progressão. Este artigo analisa os tipos mais comuns de artefatos no relatório de tomografia de coerência óptica que podem ser confundidos com danos glaucomatosos. Nós nos concentramos principalmente nos artefatos relacionados à anatomia em que a segmentação da camada da retina e as medidas de espessura estão corretas. Nesses casos, os mapas de probabilidade (também conhecidos como mapas de desvio) mostram regiões anormais (vermelho e amarelo), o que pode induzir o clínico em erro ao supor que a doença está presente. Isto se deve à variabilidade anatômica do indivíduo, e o banco de dados normativo deve ser levado em conta.

Solid Papillary Carcinoma (SPC) of the breast is a rare tumor with an incidence of less than 1%, mainly affecting elderly females. It is morphologically characterized by well-defined nodules with low-grade nuclear features associated with fibrovascular cores and shows neuroendocrine differentiation. SPC can be in-situ or invasive but has a favorable prognosis. It is a morphological mimicker of some pre-malignant conditions leading to its frequent misdiagnosis. An appropriate immunohistochemical (IHC) panel workup helps in distinguishing this tumor from its various morphological mimics. In this report, we present one such case of SPC with a small focus of invasion, reviewing the literature.

Introduction: cognitive biases might affect decision-making processes such as clinical reasoning and confirmation bias is among the most important ones. The use of strategies that stimulate deliberate reflection during the diagnostic process seems to reduce availability bias, but its effect in reducing confirmation bias needs to be evaluated. Aims: to examine whether deliberate reflection reduces confirmation bias and increases the diagnostic accuracy of orthopedic residents solving written clinical cases. Methods: experimental study comparing the diagnostic accuracy of orthopedic residents in the resolution of eight written clinical cases containing a referral diagnosis. Half of the written cases had a wrong referral diagnosis. One group of residents used deliberate reflection (RG), which stimulates comparison and contrast of clinical hypotheses in a systematic manner, and a control group (CG), was asked to provide differential diagnoses with no further instruction. The study included 55 third-year orthopedic residents, 27 allocated to the RG and 28 to the CG. Results: residents on the RG had higher diagnostic scores than the CG for clinical cases with a correct referral diagnosis (62.0±20.1 vs. 49.1±21.0 respectively; p = 0.021). For clinical cases with incorrect referral diagnosis, diagnostic accuracy was similar between residents on the RG and those on the CG (39.8±24.3 vs. 44.6±26.7 respectively; p = 0.662). We observed an overall confirmation bias in 26.3% of initial diagnoses (non-analytic phase) and 19.5% of final diagnoses (analytic phase) when solving clinical cases with incorrect referral diagnosis. Residents from RG showed a reduction in confirmation of incorrect referral diagnosis when comparing the initial diagnosis given in the non-analytic phase with the one provided as the final diagnosis (25.9±17.7 vs. 17.6±18.1, respectively; Cohen d: 0.46; p = 0.003). In the CG, the reduction in the confirmation of incorrect diagnosis was not statistically significant. Conclusions:confirmation bias was present when residents solved written clinical cases with incorrect referral diagnoses, and deliberate reflection reduced such bias. Despite the reduction in confirmation bias, diagnostic accuracy of residents from the RG was similar to those from the CG when solving the set of clinical cases with a wrong referral diagnosis.

Introdução: os vieses cognitivos podem afetar tanto os processos de tomada de decisão como o raciocínio clínico e o viés de confirmação está entre os mais importantes. O uso de estratégias que estimulem a reflexão deliberada durante o processo diagnóstico parece reduzir o viés de disponibilidade, mas seu efeito na redução do viés de confirmação precisa ser avaliado. Objetivos: examinar se a reflexão deliberada reduz o viés de confirmação e aumenta a acurácia do diagnóstico de residentes de ortopedia ao resolverem casos clínicos escritos. Métodos: estudo experimental comparando a acurácia diagnóstica de residentes de ortopedia na resolução de oito casos clínicos escritos contendo um diagnóstico de encaminhamento. Metade dos casos escritos tinha um diagnóstico de encaminhamento errado. Um grupo de residentes utilizou a reflexão deliberada (GR), que estimula a comparação e o contraste de hipóteses clínicas de maneira sistemática, e um grupo controle (GC) foi solicitado a fornecer diagnósticos diferenciais sem maiores instruções. O estudo incluiu 55 residentes de ortopedia do terceiro ano, 27 alocados no GR e 28 no GC. Resultados: residentes no GR tiveram escores diagnósticos mais altos do que o GC para casos clínicos com um diagnóstico de encaminhamento correto (62,0±20,1 vs. 49,1±21,0 respectivamente; p = 0,021). Para os casos clínicos com diagnóstico de encaminhamento incorreto, a acurácia diagnóstica foi semelhante entre os residentes do GR e os do GC (39,8±24,3 vs. 44,6±26,7 respectivamente; p = 0,662). Observamos viés geral de confirmação em 26,3% dos diagnósticos iniciais (fase não analítica) e 19,5% dos diagnósticos finais (fase analítica) na resolução de casos clínicos com diagnóstico de encaminhamento incorreto. Os residentes do GR mostraram uma redução na confirmação do diagnóstico de encaminhamento incorreto ao comparar o diagnóstico inicial dado na fase não analítica com aquele fornecido como diagnóstico final (25,9±17,7 vs. 17,6±18,1, respectivamente; Cohen d: 0,46; p = 0,003). No GC, a redução na confirmação do diagnóstico incorreto não foi estatisticamente significativa. Conclusões: o viés de confirmação esteve presente quando os residentes resolveram casos clínicos escritos com diagnósticos de encaminhamento incorretos e a reflexão deliberada reduziu esse viés. Apesar da redução do viés de confirmação, a acurácia diagnóstica dos residentes do GR foi semelhante à do GC na solução do conjunto de casos clínicos com diagnóstico de encaminhamento incorreto.

Abstract Objective To characterize the national and international scientific production on errors in health work from 2000 to 2020. Methods This is an integrative literature review of national and international studies, carried out in the MEDLINE, LILACS/BIREME, PubMed and SciELO databases. A total of 4164 studies were found, 148 of which were included and submitted to thematic content analysis. The searches were carried out from January to March 2020 and April 2021. The results were systematized into three thematic categories. Results In the category Characteristics of studies on errors, it was evidenced that the most frequent professional categories in error occurrence are nurses, physicians and pharmacists; regarding Characteristics of error in health work, the most reported types are medication, diagnosis and nursing care errors, including patient falls., phlebitis resulting from peripheral venous catheters, occurrence of pressure ulcers and extubation of drains, catheters and probes; and in Context for error occurrence, individual elements and work context were identified, highlighting the latter. Conclusion It was evident that error in health work occurs in a context of precarious work, with work processes marked by heterogeneity. From the understanding that health workers make mistakes and that the precariousness of work enhances error occurrence, it is necessary to reorganize health systems so that the opportunities for errors to occur are reduced and that learning is promoted when they occur.

Objective: This study aimed to determine the sigma metrics of analytes when using different total allowable error guidelines.Methods: A retrospective analysis was performed on 19 general chemistry analytes at Charlotte Maxeke Johannesburg Academic Hospital in South Africa between January 2017 and December 2017. Sigma metrics were calculated on two identical analysers, using internal quality control data and total allowable error guidelines from the Ricos biological variation database and three alternative sources (the Royal College of Pathologists of Australasia, the Clinical Laboratory Improvements Amendment, and the European Federation of Clinical Chemistry and Laboratory Medicine). Results: The sigma performance was similar on both analysers but varied based on the guideline used, with the Clinical Laboratory Improvements Amendment guidelines resulting in the best sigma metrics (53% of analytes on one analyser and 46% on the other had acceptable sigma metrics) and the Royal College of Pathologists of Australia guidelines being the most stringent (21% and 23%). Sodium and chloride performed poorly across all guidelines (sigma < 3). There were also month-to-month variations that may result in acceptable sigma despite poor performance during certain months.Conclusion: The sigma varies greatly depending on the total allowable error, but could be a valuable tool to save time and decrease costs in high-volume laboratories. Sigma metrics calculations need to be standardised
