Tumor metastásico en tejido blando a nivel del sacro secundario a carcinoma de células claras de riñón. Reporte de caso / Metastatic tumor in soft tissue at the level of the sacrum secondary toclear cell carcinoma of the kidney. A case report

Introducción. El cáncer de riñón es la undécima neoplasia maligna más común en los Estados Unidos Mexicanos. El carcinoma de células claras de riñón (CCR) es considerado la estirpe más frecuente y representa el 2-3 % de todos los cánceres a nivel mundial. En el contexto de la enfermedad metastásica, por lo general se identifica un tumor renal primario y las metástasis se localizan en pulmón, hueso, hígado, cerebro y, raramente, en tejidos blandos. Los pacientes con metástasis a tejidos blandos no tienen síntomas en las etapas iniciales y generalmente se identifican sólo cuando las lesiones aumentan de tamaño o durante el estudio de la pieza de resección quirúrgica. Caso clínico. Se presenta el caso de una paciente en la séptima década de la vida, con una metástasis en tejidos blandos de la región sacra, de 10 años de evolución posterior a una nefrectomía secundario a CCR. Resultados. Hallazgos clínicos e imagenológicos de un tumor bien delimitado. Se realizó resección quirúrgica de la lesión, bajo anestesia regional, con extirpación completa. Conclusión. Se recomienda que los pacientes con un sitio metastásico resecable y solitario sean llevados a resección quirúrgica con márgenes libres, como fue el caso de nuestra paciente, por su fácil acceso y ser una lesión única. En el CCR, además de su tratamiento quirúrgico inicial, es indispensable una estrecha vigilancia con examen físico e imágenes transversales, para detectar la presencia de metástasis y con ello evitar tratamientos tardíos.

Introduction. Kidney cancer is the eleventh most common malignancy in the United States of Mexico. Carcinoma renal cell (CRC) is considered the most frequent type and represents 2-3% of all cancers worldwide. In the setting of metastatic disease, a primary renal tumor is usually identified, and metastases are located in the lung, bone, liver, brain, and rarely in soft tissue. Patients with soft tissue metastases do not have symptoms in the initial stages and are generally found only when the lesions increase in size or during the study of the surgical resection piece. Clinical case. In this case, we report a female patient in the seventh decade of life with a soft tissue metastasis located in the sacral region, 10 years after a nephrectomy secondary to CRC. Results. Clinical and radiological findings of a well-defined tumor. Surgical resection of the lesion is performed under regional anesthesia with complete excision. Conclusions. It is recommended that patients with a resectable and solitary metastatic site be candidates for surgical resection with free margins, as was the case with our patient due to its easy access and single lesion. In CRC, in addition to its initial surgical treatment, close surveillance with physical examination and cross-sectional images is essential to monitor the presence of metastases and thus avoid late treatments.

The role of trimethylamine-N-oxide level in the diagnosis of diabetic retinopathy and the differential diagnosis of diabetic and nondiabetic retinopathy / Papel do nível de N-óxido de trimetilamina no diagnóstico da retinopatia diabética e no diagnóstico diferencial da retinopatia diabética e não-diabética

ABSTRACT Purpose: Trimethylamine N-oxide serum levels have been associated with type 2 diabetes mellitus and its complications. The current study aimed to find out if plasma trimethylamine N-oxide level may be a novel marker in the diagnosis of diabetic retinopathy and if it can be used in the differential diagnosis of diabetic and nondiabetic retinopathy. Methods: The study included 30 patients with diabetic retinopathy, 30 patients with nondiabetic retinopathy, 30 patients with type 2 diabetes mellitus without retinopathy, and 30 healthy control participants. Biochemical parameters, serum IL-6, TNF-α, and trimethylamine N-oxide levels were measured in all participants. Results: Trimethylamine N-oxide level was significantly higher in diabetic retinopathy than in the other groups (p<0.001). There was no significant difference in trimethylamine N-oxide levels between nondiabetic retinopathy and control or type 2 diabetes mellitus Groups. There was a significant positive correlation between trimethylamine N-oxide level and elevated FPG, BMI, HOMA-IR score, BUN, IL-6, and TNF-α levels. Conclusion: The current study showed that the trimethylamine N-oxide level is elevated in diabetic retinopathy. These findings suggest that serum trimethylamine N-oxide level might be a novel marker for diabetic retinopathy, and it might be used in the differential diagnosis of diabetic and nondiabetic retinopathy.

RESUMO Objetivo: Os níveis séricos de N-óxido de trimetilamina têm sido associados ao diabetes mellitus tipo 2 e suas complicações. O presente estudo tem como objetivo responder a duas questões, entre elas: O nível plasmático de N-óxido de trimetilamina poderia ser um novo marcador no diagnóstico de retinopatia diabética? e Ele poderia ser utilizado no diagnóstico diferencial de retinopatia diabética e não diabética? Métodos: Trinta pacientes com retinopatia diabética, 30 pacientes com retinopatia não diabética, 30 pacientes com diabetes mellitus tipo 2 sem retinopatia e 30 participantes saudáveis do grupo controle foram incluídos no estudo. Parâmetros bioquímicos, níveis séricos de IL-6, de TNF-α e de N-óxido de trimetilamina foram medidos em todos os participantes. Resultados: O nível de N-óxido de trimetilamina foi significativamente maior na retinopatia diabética do que nos outros grupos (p<0,001). Não houve diferença significativa no nível de N-óxido de trimetilamina entre o grupo de retinopatia não diabética, do grupo controle ou do grupo de diabetes mellitus tipo 2. Houve uma correlação positiva significativa entre o nível de N-óxido de trimetilamina e os níveis elevados de FPG, IMC, HOMA-IR, BUN, IL-6 e TNF-α. Conclusão: O estudo atual mostrou que o nível de N-óxido de trimetilamina encontra-se elevado na retinopatia diabética. Esses achados sugerem que o nível sérico de N-óxido de trimetilamina pode ser um novo marcador na retinopatia diabética, podendo ser usado no diagnóstico diferencial de retinopatia diabética e não diabética.

The decision-making skills of Brazilian physical therapists for patients with red flags / Capacidade da tomada de decisão dos fisioterapeutas brasileiros para pacientes com bandeiras vermelhas

ABSTRACT BACKGROUND AND OBJECTIVES: The red flags screening purpose is to ensure that signs and symptoms that raise suspicion of serious diseases are being considered during the assessment, assisting physical therapists in their clinical decision process. Brazilian physical therapists are autonomous and can act as first contact professionals in the management of musculoskeletal disorders, therefore, they need to know how to recognize, screen and refer patients with red flags for better therapeutic management. The objectives of this study were to verify whether Brazilian physical therapists can recognize and manage patients who presented red flags, compare professionals' skills regarding different academic degree levels and clinical experience and identify which factors can influence the results. METHODS: A cross-sectional and quantitative research was conducted, collected from an online questionnaire. The target audience consisted of Brazilian physical therapists who have clinical experience in the management of patients with musculoskeletal disorders. Participants filled demographic data and made clinical decisions based on six clinical cases created by the authors, based on the literature, and reviewed by three experts. Data were analyzed using descriptive statistics, the Chi-square test of independence and logistic regression. RESULTS: The study analyzed 384 answers from Brazilian physical therapists with clinical experience in musculoskeletal conditions. Brazilian physical therapists, in general, have not shown to be able to properly recognize and manage the clinical cases involving red flags, with 23.2% of the sample performing appropriate management for medical conditions, 53.9% for emergency conditions and 61.8% for medical conditions with associated musculoskeletal dysfunction. More years of clinical experience and post-professional education did not positively influence the outcomes. Higher academic degrees (Doctorate) can influence positively on the management of non-emergency medical conditions. CONCLUSION: Brazilian physical therapists who work with patients with musculoskeletal disorders perform poorly in identifying red flags in hypothetical clinical cases.

RESUMO JUSTIFICATIVA E OBJETIVOS: O objetivo da triagem de bandeiras vermelhas é garantir que sinais e sintomas que levantam suspeitas de doenças graves sejam considerados durante a avaliação, auxiliando os fisioterapeutas no seu processo de decisão clínica. Os fisioterapeutas brasileiros são autônomos e podem atuar como profissionais de primeiro contato no manejo de distúrbios musculoesqueléticos, portanto, precisam saber reconhecer, rastrear e encaminhar pacientes com bandeiras vermelhas para melhor manejo terapêutico. Os objetivos deste estudo foram verificar se os fisioterapeutas brasileiros conseguem reconhecer e tratar pacientes que apresentavam bandeiras vermelhas, comparar as habilidades dos profissionais com diferentes níveis de formação acadêmica e experiência clínica e identificar quais fatores podem influenciar os resultados. METHODS: Uma pesquisa transversal e quantitativa foi realizada, coletada através de um questionário online. O público-alvo consistiu em fisioterapeutas brasileiros com experiência clínica no manejo de pacientes com disfunções musculoesqueléticas. Os participantes preencheram dados demográficos e tomaram decisões clínicas com base em seis casos clínicos criados pelos autores, com base na literatura, e revisados por três especialistas. Os dados foram analisados por estatísticas descritivas, pelo teste qui-quadrado de independência e por regressão logística. RESULTADOS: Foram analisadas 384 respostas de fisioterapeutas brasileiros com experiência clínica em disfunções musculoesqueléticas. Os fisioterapeutas brasileiros, em geral, não demonstraram ser capazes de reconhecer e manejar adequadamente os casos clínicos envolvendo bandeiras vermelhas, com 23,2% da amostra realizando manejo adequado para condições médicas, 53,9% para condições de emergência e 61,8% para condições médicas com disfunção musculoesquelética associada. Mais anos de experiência clínica e educação pós-profissional não influenciaram positivamente os resultados. Graus acadêmicos mais elevados (Doutorado) podem influenciar positivamente no manejo de condições médicas não emergenciais. RESULTADOS: Foram analisadas 384 respostas de fisioterapeutas brasileiros com experiência clínica em disfunções musculoesqueléticas. Os fisioterapeutas brasileiros, em geral, não demonstraram ser capazes de reconhecer e manejar adequadamente os casos clínicos envolvendo bandeiras vermelhas, com 23,2% da amostra realizando manejo adequado para condições médicas, 53,9% para condições de emergência e 61,8% para condições médicas com disfunção musculoesquelética associada. Mais anos de experiência clínica e educação pós-profissional não influenciaram positivamente os resultados. Graus acadêmicos mais elevados (Doutorado) podem influenciar positivamente no manejo de condições médicas não emergenciais. CONCLUSÃO: Fisioterapeutas brasileiros que atuam com pacientes com disfunções musculoesqueléticas apresentam um mau desempenho na identificação de bandeiras vermelhas em casos clínicos hipotéticos.

Brazilian Psychiatric Association guidelines on the integration of spirituality into mental health clinical practice: Part 1. Spiritual history and differential diagnosis

Objectives: To present evidence-based guidelines for clinical practice regarding religiosity and spirituality in mental health care in Brazil. Methods: A systematic review was conducted to identify potentially eligible articles indexed in the PubMed, PsycINFO, SciELO, LILACS, and Cochrane databases. A summary of recommendations and their levels of evidence was produced in accordance with Oxford Centre for Evidence-Based Medicine guidelines. Results: The systematic review identified 6,609 articles, 41 of which satisfied all inclusion criteria. Taking a spiritual history was found to be an essential part of a compassionate and culturally sensitive approach to care. It represents a way of obtaining relevant information about the patient's religiosity/spirituality, potential conflicts that could impact treatment adherence, and improve patient satisfaction. Consistent evidence shows that reported perceptual experiences are unreliable for differentiating between anomalous experiences and psychopathology. Negative symptoms, cognitive and behavioral disorganization, and functional impairment are more helpful for distinguishing pathological and non-pathological anomalous experiences. Conclusion: Considering the importance of religiosity/spirituality for many patients, a spiritual history should be routinely included in mental health care. Anomalous experiences are highly prevalent, requiring a sensitive and evidence-based approach to differential diagnosis.

Presentación clínica de patologías no malignas que simulan leucemia cutis: a propósito de dos casos / Clinical presentation of non-malignant diseases mimicking leukemia cutis: A report of two cases

La infiltración cutánea por células leucémicas conocida como leucemia cutis es una presentación infrecuente de esta patología y constituye un desafío diagnóstico. Los diagnósticos como infecciones, otras patologías neoplásicas con afectación cutánea y los trastornos histiocíticos, entre otros, constituyen los principales diagnósticos diferenciales, ya que configuran un escenario pronóstico y terapéutico diferente. Se presentan dos pacientes que fueron diagnosticados inicialmente como leucemia cutis, cuyo diagnóstico final fue de patologías no malignas.

The infiltration of leukemia cells into the skin, known as leukemia cutis, is a rare presentation of this disease and accounts for a diagnostic challenge. The main differential diagnoses include infections, other neoplastic diseases with skin involvement and histiocytic disorders, among others, as they entail different prognostic and therapeutic approaches. Here we describe two patients who were initially diagnosed with leukemia cutis, whose final diagnosis was of non-malignant diseases.

Epidermoid cysts of the orofacial region: A clinico-pathological study of 13 cases with review of literature

Background: Epidermoid cysts (ECs) are uncommon benign cystic lesions derived from the germinative epithelium. Head and neck ECs constitute only 7% of all ECs whereas only 1.6% are seen intraorally. The floor of the mouth is the commonest intraoral site whereas tongue, lips, buccal mucosa, and jaws are less commonly involved intraoral sites. To date, very few large case series of ECs of head and neck have been published. To the best of our knowledge, this is the third-largest case series of 11 intraoral ECs along with 2 extra-oral cases in the pre-auricular region. Aims: To highlight the typical and atypical features of ECs in the common as well as rare sites and draw attention to its consideration as a differential diagnosis for head and neck masses. Settings and Design: Archival data of 13 histopathological cases identified as ECs were analyzed from the Department of Oral Pathology at a tertiary dental hospital and college in New Delhi from 2007 to 2020. Materials and Methods: The demographic, clinical, radiographic, histopathological features, and treatment modalities were recorded and analyzed. Statistical Analysis Used: Appropriate statistical tests were used. Results: The study found strong male predilection in the ratio of 10:3 with an average age of presentation as 28 years. The pre-auricular region and floor of the mouth were the common sites involved followed by buccal mucosa, lips, and jaws. All patients presented with slowly growing swelling with dysphagia, dyspnea, and dysphonia seen in larger cysts on the floor of the mouth. Microscopically, all cases were lined with stratified squamous epithelium filled with laminated layers of keratin. Two cases showed the presence of melanin. One case showed recurrence even after complete surgical excision. Conclusion: ECs, though a rare entity, should be considered in differential diagnosis for head and neck masses and require close follow-up due to their potential for malignant transformation.

Crohn's Disease in a Patient with Tuberculosis: A Diagnostic and Therapeutic Challenge

Introduction: Crohn's disease (CD) is unusual in Colombia. Tuberculosis (TB) occurs more frequently, but intestinal involvement is rare. Differentiating these two entities and treating the cases in which they coexist is a challenge. Clinical case: A 28-year-old man with three months of constitutional, respiratory, and GI symptoms was initially diagnosed with pulmonary tuberculosis, and all the clinical manifestations were attributed to this entity. Given the absence of improvement with treatment and the sum of radiological, endoscopic, and pathological findings, CD was confirmed. Treatment was complex due to the coexistence of the two entities, although he finally went into remission with the use of biologicals. Discussion: Diagnosing CD requires the sum of clinical and paraclinical findings. A therapeutic test may be necessary to differentiate it from intestinal TB. The treatment of CD in a patient with TB has some limitations; steroids are not contraindicated, and biologicals must be initiated cautiously. Conclusions: Differentiating CD from intestinal TB is a diagnostic challenge. Therapeutic management when these two entities coexist requires an interdisciplinary approach.

Introducción: la enfermedad de Crohn (EC) es inusual en Colombia. La tuberculosis (TB) se presenta con mayor frecuencia, pero el compromiso intestinal es raro. Diferenciar estas dos entidades y el tratamiento de los casos en los que coexisten es un reto. Caso clínico: hombre de 28 años con 3 meses de síntomas constitucionales, respiratorios y gastrointestinales al que en un inicio se le confirmó el diagnóstico de tuberculosis pulmonar y se le atribuyó a esta entidad todas las manifestaciones clínicas. Ante la ausencia de mejoría con el tratamiento y la suma de hallazgos radiológicos, endoscópicos y patológicos, se confirmó EC. El tratamiento fue difícil debido a la coexistencia de las dos entidades, aunque finalmente presentó remisión con el uso de biológicos. Discusión: diagnosticar la EC requiere de la sumatoria de hallazgos clínicos y paraclínicos. Para diferenciarla de TB intestinal puede llegar a ser necesaria una prueba terapéutica. El tratamiento de EC en un paciente con TB tiene algunas limitaciones, los esteroides no se contraindican de manera absoluta y el inicio de biológicos debe hacerse con precaución. Conclusiones: diferenciar la EC de la TB intestinal es un reto diagnóstico. El enfoque terapéutico cuando coexisten estas dos entidades requiere un abordaje interdisciplinario.

Differential Diagnosis of Oral Metastases / Diagnóstico Diferencial de las Metástasis Orales

Metastatic lesions in the mouth can resemble common inflammatory lesions. Therefore, we set out to investigate oral metastases whose clinical and imaging characteristics mimicked those of harmless lesions, confusing and delaying the diagnosis. For this, a systematic review was carried out from case reports, case series, and cross-sectional studies in the PubMed/Medline, Scopus, Embase-via Elsevier, Virtual Health Library, Web of Science, and gray literature, using PICO strategy without period restriction. We assessed the quality of studies using the Joanna Briggs Institute assessment tool. A narrative synthesis of the data was carried out. Association analyses using chi-square and Fisher's exact tests were performed, with statistical significance at p<0.05. Most of the lesions came from the lung, breast, kidneys, liver, and thyroid. They affected mainly the mandibles of men, between the fifth and seventh decades of life, causing osteolysis. In soft tissue, there were firm swellings, associated with bleeding. Limitations regarding the heterogeneity of the included studies and the absence of clinic pathological descriptions of the tumors substantially reduced the chance of statistical analysis of the data. Knowing the different possibilities of clinical presentation of oral and maxillofacial metastases is important for the diagnost ic suspicion to occur and diagnostic errors to be avoided. Thus, treatment is instituted and survival can be extended. Protocol registration: PROSPERO CRD42020200696.

Las lesiones metastásicas en la cavidad oral pueden parecer similares a lesiones inflamatorias comunes. Por ello, nos propusimos investigar metástasis orales cuyas características clínicas e imagenológicas simularan las de lesiones inofensivas, confundiendo y retrasando el diagnóstico. Para ello, se realizó una revisión sistemática a partir de reportes de casos, series de casos y estudios transversales en PubMed/Medline, Scopus, Embase-vía Elsevier, Virtual Health Library, Web of Science y literatura gris, utilizando la estrategia PICO sin restricción de periodo. La calidad de los estudios se evaluó mediante la herramienta de evaluación del Instituto Joanna Briggs. Se realizó una síntesis narrativa de los datos. Se realizaron análisis de asociación mediante chi-cuadrado y prueba exacta de Fisher, con significancia estadística en p<0,05. La mayoría de las lesiones procedían de pulmón, mama, riñones, hígado y tiroides. Afectan principalmente a las mandíbulas de los hombres, entre la quinta y la séptima década de la vida, provocando osteólisis. En los tejidos blandos, había hinchazones firmes, asociadas con sangrado. Las limitaciones con respecto a la heterogeneidad de los estudios incluidos y la ausencia de descripciones clinicopatológicas de los tumores redujeron sustancialmente la posibilidad de realizar un análisis estadístico de los datos. Conocer las diferentes posibilidades de presentación clínica de las metástasis orales y maxilofaciales es importante para que se produzca la sospecha diagnóstica y se eviten errores diagnósticos. Por lo tanto, se instituye el tratamiento y se puede prolongar la supervivencia. Registro de protocolo: PROSPERO CRD42020200696.

Solitary fibrous tumor: Two cases report with a focus on the differential diagnosis / Tumor Fibroso Solitário: Relato de dois casos com foco no diagnóstico diferencial

Solitary fibrous tumor (SFT) is a neoplasm of fibroblastic/myofibroblastic origin with intermediate biological behavior. We report here two cases of SFT affecting an unusual anatomical site in 58-year-old and 40-year-old female patients and discuss the differential diagnosis of this lesion. In case 01, the lesion showed the clinical appearance of an asymptomatic "blister" with normal color, rubbery consistency, measuring 0.3 cm, and affected the lower lip; while in case 02, a symptomatic red nodular lesion with a soft consistency and measuring 0.5 cm affected the floor of the mouth. Excisional biopsies were performed. Microscopically, two well-delimited benign neoplasms were observed, exhibiting the proliferation of ovoid to spindle-shaped mesenchymal cells, vascular spaces with staghorn arrangement, and the absence of mitosis figures. Immunohistochemistry was performed in case 01 to assist in the diagnosis. Weak and diffuse immunostaining was observed for α-SMA and intense and diffuse immunopositivity for Bcl-2 and CD34. Based on histopathological and immunohistochemical features, a diagnosis of SFT was rendered in both cases. The low occurrence and nonspecific clinical features of oral SFT may make its clinical diagnosis difficult. Also, morphological and immunohistochemical are essential for differential diagnosis with other mesenchymal neoplasms.(AU)

O tumor fibroso solitário (TFS) é uma neoplasia de origem fibroblástica/miofibroblastica com comportamento biológico intermediário. Nesse artigo relatamos dois casos de TFS afetando sítios anatômicos incomuns em pacientes do sexo feminino de 58 anos e 40 anos e discutir os seus diagnósticos. No caso 01 clinicamente a lesão apresentou um aspecto de "bolha" assintomática, coloração normal da mucosa, consistência borrachoide medindo 0,3 cm, em região de lábio inferior, enquanto que no caso 02, como uma lesão sintomática, vermelha, nodular com consistência mole e medindo 0,5 cm afetando o assoalho bucal. As biópsias excecionais foram realizadas. Microscopicamente, observamos duas lesões neoplásicas bem delimitadas exibindo uma proliferação de células mesenquimais variando de ovoides a fusiformes, vasos sanguíneos em formato de "chifre de veado", com ausência de figuras de mitoses. No caso 01 foi realizado análise imuno-histoquímica para auxiliar no diagnóstico. Foi observado uma marcação fraca e difusa de α-SMA e uma intensa e difusa imunopositividade para o Bcl-2 e CD34.Baseado nos achados histopatológicos e imuno-histoquímicos o diagnóstico de TFS foi estabelecido em ambos os casos. A baixa ocorrência e os achados clínicos inespecíficos do TFS oral podem dificultar o diagnóstico clínico. Além disso, as análises morfológicas e imuno-histoquimicas são essenciais para realização do diagnóstico diferencial com outras neoplasias mesenquimais.(AU)_

La importancia del cribado orgánico. A propósito de un caso clínico

Introducción: Antes de catalogar un proceso morboso como trastorno mental, es imprescindible tener presente la importancia del diagnóstico precoz de causas de origen no psiquiátrico para una posible presentación clínica. Por ello, trataremos de reflejar este hecho, que se antoja necesario recordar aunque sea bien sabido, ya que puede pasarse por alto en situaciones de urgencia en el ámbito hospitalario, con las consecuencias derivadas de un cribado incompleto y con el potencial riesgo vital para el paciente. Presentación del caso: Adolescente mujer, de 13 años, que presentó un cuadro clínico agudosugestivo de carácter disociativo. Se precisó su ingreso hospitalario para la aclaración diagnóstico-terapéutica, y mediante neuroimagen se diagnosticó inicialmente como lesión neoplásica en el tronco del encéfalo y, finalmente, como lesión isquémica de origen vasculítico en dicha localización. Discusión: Se planteó un diagnóstico diferencial a través de las diferentes etiologías tanto psíquicas como no psíquicas del cuadro clínico, pero fue necesaria la intervención del servicio de pediatría hospitalario para la orientación y filiación definitiva, ante la sospecha de enfermedad no psiquiátrica tras una evolución tórpida a pesar de intervenciones psicoterapéuticas y psicofarmacológicas. Conclusiones: A través de la presentación y revisión de un caso clínico que sucedió en nuestro hospital de trabajo, se debe insistir en un adecuado abordaje integral del paciente, especialmente con población infanto-juvenil, ante una presentación clínica aguda y sin previas evaluaciones físicas de relevancia.

Introduction: Before cataloguing a morbid process as a "mental disorder", it is essential to bear in mind the importance of early diagnosis of causes of non-psychiatric origin for a possible clinical presentation. For this reason, we will try to reflect this fact, which it seems necessary to remember even though it is well known, since it can be overlooked in emergency situations in the hospital setting, with the consequences derived from an incomplete diagnosis and with the potential life-threatening risk for the patient. Case presentation: A 13-year-old female adolescent, who presented an acute clinical picture suggestive of dissociative disorder. She required hospital admission for diagnostic-therapeutic clarification, and neuroimaging findings led to an initial diagnosis of a neoplastic lesion in the brain stem and, finally, as ischaemic lesion of vasculitic origin in said location. Discussion: A differential diagnosis was proposed through the different psychic and nonpsychic aetiologies of the clinical picture, being the intervention of the hospital's paediatric service necessary for orientation and definitive affiliation, given the suspicion of non-psychiatric illness after a torpid evolution in spite of psychotherapeutic and psychopharmacological interventions. Conclusions: Through the presentation and review of a clinical case that happened in our hospital, we must insist on an adequate comprehensive approach to the patient, especially with the child-adolescent population, when faced with an acute clinical presentation and without previous studies at a relevant physical level.

Apendagitis aguda como causa infrecuente de abdomen agudo quirúrgico. Reporte de caso / Acute Appendagitis as a Rare Cause of Surgical Acute Abdomen. Case Report

Resumen Introducción: El dolor abdominal se constituye como uno de los motivos de consulta más frecuentes en los servicios de urgencias, su adecuado abordaje diagnóstico determina el tratamiento a elegir por parte del médico a cargo del caso; este a su vez puede optar por un manejo médico o quirúrgico, todo esto si se considera la causa subyacente de la sintomatología que presenta el paciente. Caso clínico: En el presente artículo se presenta el caso de un paciente del sexo masculino en la quinta década de la vida, con antecedente quirúrgico de apendicetomía; el cual consulta por cuadro clínico de dolor abdominal intenso de localización en la fosa iliaca derecha. En el examen físico fue llamativa la presencia de signos de irritación peritoneal, por lo cual se solicitaron estudios serológicos que se encontraron dentro de los parámetros normales, además una tomografía computada de abdomen que reveló trabeculación de grasa pericecal. El paciente persistió sintomático, por lo que fue llevado a exploración vía abierta de la cavidad abdominal, con hallazgo intraoperatorio de apendagitis aguda. Conclusión: A pesar de ser una causa infrecuente de abdomen agudo quirúrgico, la apendagitis aguda siempre debe ser un diagnóstico a considerar por parte de los médicos de urgencias y los cirujanos. El disponer de estudios de imagen que permitan una adecuada caracterización del cuadro clínico va a ser fundamental para el manejo de los pacientes, más, si se tiene en cuenta toda la variedad de entidades que se presentan en la cavidad abdominal.

Abstract Introduction: Abdominal pain is one of the most frequent reasons for consultation in the emergency services, its adequate diagnostic approach determines the treatment to be chosen by the doctor in charge of the case; This in turn can opt for medical or surgical management, all this if the underlying cause of the symptoms presented by the patient is considered. Clinical case: This article presents the case of a male patient in the fifth decade of life, with a surgical history of appendectomy, which he consults due to a clinical picture of intense abdominal pain located in the right iliac fossa. In the physical examination, the presence of signs of peritoneal irritation was striking, for which serological studies were requested, which were found to be within normal parameters, in addition to a computed tomography of the abdomen that revealed trabeculation of pericecal fat. The patient persisted with symptoms, so he was taken for open abdominal cavity exploration, with an intraoperative finding of acute appendagitis. Conclusion: Despite being an infrequent cause of acute surgical abdomen, acute appendagitis should always be a diagnosis to be considered by emergency physicians and surgeons. The availability of imaging studies that allow an adequate characterization of the clinical picture is going to be essential for the management of patients, especially if the whole variety of entities that occur in the abdominal cavity are taken into account.

Quiste hidatídico de la glándula tiroides: Reporte de tres casos

Introducción: La enfermedad hidatídica puede desarrollarse en cualquier órgano del cuerpo, siendo las localizaciones más frecuentes el hígado y pulmón, pero ocasionalmente puede afectar a otros órganos como la glándula tiroides. En Chile existen escasas publicaciones previas. El objetivo de este reporte es presentar el diagnóstico, tratamiento y seguimiento de tres pacientes portadores de quiste hidatídico de la glándula tiroides. Casos Clínicos: Se refiere a dos mujeres de 9 y 56 años y un paciente de sexo masculino de 56 años, provenientes de la zona rural de la Región de Aysén en la Patagonia, todos enviados por aumento de volumen sintomático de la glándula tiroides. El diagnóstico presuntivo se realizó mediante los antecedentes anamnésticos e imágenes de ultrasonografía. Todos fueron sometidos a tiroidectomía subtotal y a quimioprofilaxis post operatoria con Albendazol por 30 días. La confirmación diagnóstica se realizó mediante el estudio histopatológico. Ninguno ha presentado recurrencia, llevando una de ellas 22 años de seguimiento. Conclusión: Aunque la glándula tiroides rara vez se ve afectada, la enfermedad hidatídica no debe pasarse por alto en el diagnóstico diferencial de lesiones quísticas de la glándula, especialmente en pacientes que viven en regiones donde la enfermedad es endémica.

Introduction: Hydatid disease can develop in any organ of the body, the most frequent locations being the liver and lung, but occasionally it can affect other organs such as the thyroid gland. In Chile there are few previous publications. Aim: The aim of this report is to present the diagnosis, treatment and follow-up of three patients with hydatid thyroid cysts. Clinical Cases: Two women, ages 9 and 56, and a 56 year old male patient, referred from Aysén in Patagonia, all of them due to a symptomatic increased volume in thyroid gland. The diagnosis was made through anamnestic history and ultrasound images. All underwent subtotal thyroidectomy and postoperative chemoprophylaxis with Albendazole for 30 days. Diagnostic confirmation was made by histopathological study. None had recurrence, one of them has been followed for 22 years. Conclusion: In conclusion, although the thyroid gland is rarely affected, hydatid disease should not be overlooked in the differential diagnosis of cystic lesions of the thyroid gland, especially in patients living in regions where the disease is endemic.

Hamartoma adquirido de músculo liso: reporte de caso / Acquired smooth muscle hamartoma: case report / Hamartoma adquirido de músculo liso: reporte de caso

RESUMEN El hamartoma de músculo liso es una malformación cutánea poco común y benigna, congénita o adquirida. En la bibliografía se describen otras enfermedades superpuestas, como la melanosis de Becker, especialmente en el caso de lesiones con hipertricosis e hiperpigmentación. Describimos a un paciente masculino de 21 años con hamartoma de músculo liso adquirido, que es una manifestación rara y con pocos reportes descritos. Destacamos la necesidad de valorar una posible asociación con la melanosis de Becker, enfatizando que los aspectos clínicos, aun con la histopatología, no siempre permiten la individualización.

ABSTRACT Smooth muscle hamartoma is a rare and benign cutaneous malformation, congenital or acquired. Overlapping other diseases is described in the literature, such as Becker's Melanosis, especially in the case of lesions with hypertrichosis and hyperpigmentation. We describe here a 21-year-old male patient with acquired smooth muscle hamartoma, which is a rare manifestation and with few reports described. We emphasize the need to assess a possible association with Becker's melanosis, emphasizing that clinical aspects, even when reconciled with histopathology, do not always allow for individualization.

RESUMO O hamartoma de músculo liso é uma malformação cutânea benigna e rara, de natureza congênita ou adquirida. A sobreposição à outras doenças é descrita na literatura, como a melanose de Becker, especialmente em caso de lesões com hipertricose e hiperpigmentação. Descrevemos aqui, quadro de paciente masculino de 21 anos, com hamartoma de músculo liso adquirido, que é uma manifestação rara e com poucos relatos descritos. Ressaltamos a necessidade de avaliar possível associação com a melanose de Becker, enfatizando que nem sempre os aspectos clínicos, mesmo quando conciliados com a histopatologia, permitem a individualização.

Solid placental transmogrification of the lung: A case report and literature review / 北京大学学报(医学版)

Placental transmogrification of the lung (PTL) is a very rare benign lung lesion. There are only about 40 cases reported in the literature. The imaging and histological features of PTL cases in the publication are various, most of which are cystic and a few of which are solid. Being extremely rare, the solid PTL is unknown to major pathologists and surgeons. We reported a case of solid PTL in the anterior mediastinum. The patient was a 52-year-old male with no history of smoking and without symptoms. During physical examination, chest CT revealed a circular low-density lesion with a maximum diameter of 2.9 cm beside the spine in the posterior basal segment of the left lower lobe of the lung. The wedge resection was performed by video-assisted thoracoscopy. Grossly, a round nodule was located underneath the visceral pleura. It was about 3.0 cm×3.0 cm×1.6 cm and the cut surface was grey-red, soft and spongy. Microscopically, the nodule was constituted of papillare, which resembled placental villi at low magnification. The axis of papillae was edema, in which some mild round cells with clear cytoplasm and CD10 positive staining aggregated and transitioned to immature adipocytes and amorphous pink materials deposited with a few of inflammatory cells infiltration. The surface of papillae was covered with disconti-nuous alveolar epithelium. Combined with the typical morphology and immunohistochemical characteristics of CD10 positive, the diagnosis was PTL. The patient was followed up for 1 year without recurrence and discomfort. So far, the pathogenesis of PTL is unclear. The major hypotheses include hamartoma, variant of emphysema and clonal hyperplasia of stromal cells. Based on the study of our case and publication, we speculate that the hyperplasia of stromal cells located in the alveolar septa might be the first step to form the solid PTL. With the progression of the disease, a typical unilateral cystic nodule develops as a result of secondary cystic degeneration due to the occlusive valve effect. Surgery is the only option for diagnosis and treatment of PTL. The clinician should make an individualized operation plan according to the clinical manifestations, location and scope of the lesion, and preserve the surrounding normal lung tissue as much as possible while completely removing the lesion. There is a favorable prognosis.

Clinical value of plasma scaffold protein SEC16A in evaluating hepatitis B-related liver cirrhosis and hepatocellular carcinoma / 中华肝脏病杂志

Objective: To investigate the clinical value of plasma scaffold protein SEC16A level and related models in the diagnosis of hepatitis B virus-related liver cirrhosis (HBV-LC) and hepatocellular carcinoma (HBV-HCC). Methods: Patients with HBV-LC and HBV-HCC and a healthy control group diagnosed by clinical, laboratory examination, imaging, and liver histopathology at the Third Hospital of Hebei Medical University between June 2017 and October 2021 were selected. Plasma SEC16A level was detected using an enzyme-linked immunosorbent assay (ELISA). Serum alpha-fetoprotein (AFP) was detected using an electrochemiluminescence instrument. SPSS 26.0 and MedCalc 15.0 statistical software were used to analyze the relationship between plasma SEC16A levels and the occurrence and development of liver cirrhosis and liver cancer. A sequential logistic regression model was used to analyze relevant factors. SEC16A was established through a joint diagnostic model. Receiver operating characteristic curve was used to evaluate the clinical efficacy of the model for liver cirrhosis and hepatocellular carcinoma diagnosis. Pearson correlation analysis was used to identify the influencing factors of novel diagnostic biomarkers. Results: A total of 60 cases of healthy controls, 60 cases of HBV-LC, and 52 cases of HBV-HCC were included. The average levels of plasma SEC16A were (7.41 ± 1.66) ng/ml, (10.26 ± 1.86) ng/ml, (12.79 ± 1.49) ng /ml, respectively, with P < 0.001. The sensitivity and specificity of SEC16A in the diagnosis of liver cirrhosis and hepatocellular carcinoma were 69.44% and 71.05%, and 89.36% and 88.89%, respectively. SEC16A, age, and AFP were independent risk factors for the occurrence of HBV-LC and HCC. SAA diagnostic cut-off values, sensitivity, and specificity were 26.21 and 31.46, 77.78% and 81.58%, and 87.23% and 97.22%, respectively. The sensitivity and specificity for HBV-HCC early diagnosis were 80.95% and 97.22%, respectively. Pearson correlation analysis showed that AFP level was positively correlated with alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), and γ-glutamyltransferase (GGT) with P < 0.01, while the serum SEC16A level was only slightly positively correlated with ALT and AST in the liver cirrhosis group (r = 0.268 and 0.260, respectively, P < 0.05). Conclusion: Plasma SEC16A can be used as a diagnostic marker for hepatitis B-related liver cirrhosis and hepatocellular carcinoma. SEC16A, combined with age and the AFP diagnostic model with SAA, can significantly improve the rate of HBV-LC and HBV-HCC early diagnosis. Additionally, its application is helpful for the diagnosis and differential diagnosis of the progression of HBV-related diseases.

Pathological classification of malignant peritoneal mesothelioma and comparative analysis with peritoneal carcinomatosis / 中华劳动卫生职业病杂志

Objective: To analyze the pathological classification of malignant peritoneal mesothelioma (MPeM) and screen the immunohistochemical markers that can distinguish MPeM from peritoneal metastatic carcinoma (PC) . Methods: In June 2020, the pathological results of peritoneal biopsy of 158 MPeM and 138 PC patients from Cangzhou Central Hospital, Cangzhou People's Hospital, and Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine from May 2011 to July 2019 were retrospectively analyzed, and the pathological classifications of MPeM in Cangzhou were summarized. Immunohistochemical markers of MPeM and PC patients were analyzed, and receiver operating characteristic curve (ROC curve) was drawn for differential diagnosis of MPeM and PC. Results: There were 55 male and 103 female MPeM patients in Cangzhou, with an average age of 57.1 years old. The asbestos exposure rate was 91.14% (144/158). The most common pathological classifications were cutaneous type, accounting for 90.51% (143/158). There were significant differences in the expression of calreticulum protein, CK5/6, vimentin, D2-40, carcinoembryonic antigen (CEA) and tail type homologous nuclear gene transcription factor 2 (CDX-2) between MPeM and PC (P<0.05). Among the 6 positive markers, the sensitivity of calreticulum protein was the highest (0.905) and CEA was the lowest (0.428) . Conclusion: Calreticulum protein, CK5/6, vimentin, D2-40, CEA and CDX-2 may be used as specific markers to distinguish the diagnosis of MPeM from PC.

Value for combination of T1WI star -VIBE with TWIST -VIBE dynamic contrast -enhanced MRI in distinguishing lung nodules / 中南大学学报(医学版)

OBJECTIVES@#With the increasing detection rate of lung nodules, the qualitative problem of lung nodules has become one of the key clinical issues. This study aims to evaluate the value of combining dynamic contrast-enhanced (DCE) MRI based on time-resolved imaging with interleaved stochastic trajectories-volume interpolated breath hold examination (TWIST-VIBE) with T1 weighted free-breathing star-volumetric interpolated breath hold examination (T1WI star-VIBE) in identifying benign and malignant lung nodules.@*METHODS@#We retrospectively analyzed 79 adults with undetermined lung nodules before the operation. All nodules of patients included were classified into malignant nodules (n=58) and benign nodules (n=26) based on final diagnosis. The unenhanced T1WI-VIBE, the contrast-enhanced T1WI star-VIBE, and the DCE curve based on TWIST-VIBE were performed. The corresponding qualitative [wash-in time, wash-out time, time to peak (TTP), arrival time (AT), positive enhancement integral (PEI)] and quantitative parameters [volume transfer constant (Ktrans), interstitium-to-plasma rate constant (Kep), and fractional extracellular space volume (Ve)] were evaluated. Besides, the diagnostic efficacy (sensitivity and specificity) of enhanced CT and MRI were compared.@*RESULTS@#There were significant differences in unenhanced T1WI-VIBE hypo-intensity, and type of A, B, C DCE curve type between benign and malignant lung nodules (all P<0.001). Pulmonary malignant nodules had a shorter wash-out time than benign nodules (P=0.001), and the differences of the remaining parameters were not statistically significant (all P>0.05). After T1WI star-VIBE contrast-enhanced MRI, the image quality was further improved. Compared with enhanced CT scan, the sensitivity (82.76% vs 80.50%) and the specificity (69.23% vs 57.10%) based on MRI were higher than that of CT (both P<0.001).@*CONCLUSIONS@#T1WI star-VIBE and dynamic contrast-enhanced MRI based on TWIST-VIBE were helpful to improve the image resolution and provide more information for clinical differentiation between benign and malignant lung nodules.

Self-reported clinical history of misdiagnosed leprosy cases in the State of Mato Grosso, Brazil, 2016-2019 / Histórico clínico autorreferido de casos mal classificados de hanseníase no Estado do Mato Grosso, Brasil, 2016-2019 / Historia clínica autorreportada de casos de lepra mal diagnosticados en el estado de Mato Grosso, Brasil, 2016-2019

This study aimed to analyze the self-reported clinical history of patients misdiagnosed with leprosy in the State of Mato Grosso, Brazil. This is a cross-sectional study of new leprosy cases diagnosed in the State of Mato Grosso from 2016 to 2019, with individuals who were released from multidrug therapy due to misdiagnosis after starting treatment. Data were collected via telephone interviews. Over the study period, 354 leprosy cases were released from treatment due to misdiagnosis, of which 162 (45.8%) could be interviewed. All interviewees expressed dissatisfaction with their treatment, which prompted them to seek a reevaluation of their diagnosis before they were released due to "misdiagnosis". Among them, 35.8% received a final diagnosis of a musculoskeletal or connective tissue disease - mainly fibromyalgia and degenerative changes in the spine - followed by 13.6% with diagnoses of skin and subcutaneous tissue diseases. For 23.5% of the respondents, no alternative diagnosis was established, whereas 7.4% were later re-diagnosed with leprosy. Fibromyalgia and spinal problems were the most common alternative diagnoses for erroneous leprosy. Although the diagnosis of leprosy is usually clinical and does not require access to technical infrastructure in most cases, some more complex situations require diagnostic support via complementary tests, as well as close collaboration between primary care and reference services.

O objetivo deste estudo foi analisar o histórico clínico autorreferido de pacientes diagnosticados erroneamente com hanseníase no Estado do Mato Grosso, Brasil. Trata-se de um estudo transversal de novos casos de hanseníase diagnosticados no Estado do Mato Grosso, de 2016 a 2019, que após o início da poliquimioterapia foram liberados do tratamento devido a erros de diagnóstico. Para a coleta de dados, foram realizadas entrevistas telefônicas. Durante o período do estudo, 354 indivíduos com hanseníase foram liberados do tratamento por erro de diagnóstico, dos quais 162 (45,8%) puderam ser entrevistados. Todos os entrevistados expressaram insatisfação com o tratamento, levando à reavaliação do diagnóstico antes de serem liberados por "erro de diagnóstico". Dentre eles, 35,8% tinham como diagnóstico final uma doença musculoesquelética ou do tecido conjuntivo, principalmente fibromialgia e alterações na coluna vertebral, seguidos por 13,6% com diagnósticos de doenças de pele e tecido subcutâneo. Para 23,5% dos entrevistados, nenhum diagnóstico alternativo foi estabelecido, enquanto 7,4% foram posteriormente rediagnosticados com hanseníase. Diagnósticos errôneos de hanseníase foram mais frequentemente reclassificados como fibromialgia e problemas na coluna vertebral. Embora o diagnóstico da hanseníase seja geralmente clínico e não exija acesso à infraestrutura técnica na maioria dos casos, algumas situações mais complexas requerem apoio ao diagnóstico por meio de exames complementares, bem como estreita colaboração entre a atenção primária e os serviços de referência.
