ABSTRACT

Objetivo: describir los datos sociodemográficos, las manifestaciones clínicas, los paraclínicos, el tratamiento y la recurrencia, en un grupo de pacientes con lesiones papilares. Metodología: estudio analítico de cohorte retrospectiva con fuentes secundarias de información, historias clínicas. Se incluyeron pacientes evaluados entre el 1º enero de 2016 y el 31 de diciembre de 2019. Se recopilaron datos demográficos, clínicos y paraclínicos, que fueron analizados con estadística descriptiva. Resultados: la prevalencia en la muestra fue de 4.7%; todos los casos fueron en mujeres, la media de edad fue 55,5 años; el motivo de consulta más frecuente fue alteración en la imagen de mama (n=79, 54.9%), el tamaño medio de la lesión fue 1,9 cm (rango 0,1-20). Se encontró discordancia entre el diagnóstico por biopsia cortante y el espécimen de patología en 70 (48.6%) casos, en estos se encontró infraestimación de lesiones con mayor riesgo en el 36,1% (n=52). Según la clasificación histológica, el tipo más frecuente de lesión fue el papiloma intraductal 34.7% (n=50), seguido por el carcinoma papilar en 11,8% (n=17). El tipo de cirugía más efectuado fue la cuadrantectomía, con un 68.7% (n=99). La media de seguimiento fue de 28.5 meses y se encontró recaída en siete casos (4.9%). Conclusión: las lesiones papilares comprenden un grupo heterogéneo, que incluye desde las benignas hasta aquellas con potencial maligno. Afectan a las mujeres en la quinta década de la vida, se presentan como una masa, pequeña, unilateral, sin predominio de lateralidad, de crecimiento lento. El tratamiento óptimo para las lesiones de riesgo y con atipias es la cirugía con márgenes negativos, el riesgo de recurrencia es clínicamente relevante.


Objective: to describe the sociodemographic data, the clinical and paraclinical ma-nifestations, the treatment and the recurrence, in a group of patients diagnosed with papillary lesions.Methodology:analytical study of a retrospective cohort with secondary sources of information from users' medical records in the period of January 1, 2016 to December 31, 2019. The demographic, clinical and paraclinical data collected were analyzed using descriptive statistics.Results:the prevalence in the sample was 4.7%; all cases were women, the mean age was 55.5 years; the most frequent reason for consultation was abnormal breast imaging examination (n=79, 54.9 %), the mean size was 1.9 cm (range 0,1-20). Disagreement was found between the diagnosis by sharp biopsy and the pathology specimen in 48.6% of cases (n=70); lesion underestimation with higher risk was found in 36.1% of them (n=52). According to the histological classification, the most frequent was intraductal papilloma in 34.7% (n=50), followed by papillary carcinoma in 11.8% (n=17). The type of surgery most performed was quadrantectomy, 68.7% (n=99). The mean follow-up was 28.5 months and relapse was found in 4.9% (n=7).Conclusion:papillary lesions comprise a heterogeneous group, with a spectrum that includes both benign lesions and those with malignant potential. The lesions affect women in their fifties. They become apparent as a small, unilateral mass, without a pre-dominance of laterality, and of slow growth. The optimal treatment in risk lesions and with atypia is surgery with negative margins. The risk of recurrence is clinically important.

ABSTRACT

El mixoma odontogénico es una neoplasia de origen mesenquimal, con crecimiento lento pero localmente invasivo y agresivo, que cuenta con un aspecto histológico característico. Radiográficamente, la mayoría de las lesiones tienen un aspecto radiolúcido multilocular, descrito en la literatura como «panal de abejas¼ o «burbujas de jabón¼, que ocasionan desplazamiento dental y expansión corticales. En el ámbito histopatológico, se caracteriza por células estelares o fusiformes con prolongaciones citoplasmáticas, en una sustancia mucoide o mixoide con presencia o no de colágena, cuando contiene grandes cantidades de tejido fibroso celular maduro se le llama mixofibroma. Se presenta un caso clínico de hombre de 38 años, que acude al Hospital General de Uruapan, Michoacán con aumento de volumen en región maxilar derecha; se toma biopsia incisional y se emite el diagnóstico histopatológico de mixofibroma odontogénico, 33.6% de los casos se presenta en el maxilar, con una distribución uniforme por todas las áreas llegando a erosionar el seno maxilar. Tiene una tasa de recurrencia de 10 a 33%, y el tratamiento ideal es la resección en bloque con márgenes de seguridad (AU)


Odontogenic myxoma is a slow-growing locally invasive intraosseous lesion with defined microscopic appearance. Radiographic appearance, is described as multilocular radiolucent lesion, which is reported in scientific literature as «honeycomb¼ or «soap bubbles¼ appearance most of the time; it exhibits dental displacement and cortical expansion. Histopathologically, stellate and spindle cells with cytoplasmic processes are observed in a mucoid or myxoid substance, with or without collagen; when it contains large amounts of mature cellular fibrous tissue, it is called myxofibroma. The present article presents the case of a 38 year old male, who attended the General Hospital in Uruapan, Michoacán due to an increased volume in the right maxillary region. Incisional biopsy was performed and the histopathological diagnosis of odontogenic myxofibroma was emitted. 33.6% of cases occur in the maxilla with a uniform distribution throughout the areas, and can erode the maxillary sinus. It has a recurrence rate of 10 to 33%, therefore ideal treatment is bloc resection leaving safety margins (AU)

ABSTRACT

Abstract Objective To define the effectiveness of fluoroscopy-guided percutaneous vertebral biopsy. Methods Prospective study of patients with vertebral destruction syndrome at one institution. Percutaneous transpedicular vertebral biopsies guided by fluoroscopy were performed, and bony tissue and intervertebral disc tissue were extracted; histopathology and microbiology studies were also performed. Age, sex, vertebral segment, neurologic status, and biopsy and culture results were analyzed. Results The average age of the patients was 53.8 years (range: 2 to 83 years), and the main spine segment was the lumbar segment in 62% of the cases. According to the impairment scale of the American Spinal Injury Association (ASIA), preoperatively, 49% of the patients were classified as Asia E, and 100% had pain. Definitive etiology was identified in 83% of the sample. The etiology was grouped into three categories: infectious, neoplasia, and degenerative (osteoporotic). The infectious group was composed of 36% of the patients, in whom Staphylococcus aureus was the most common agent identified; in 34.9% the sample, the etiology was neoplastic, most commonly multiple myeloma and metastatic disease due to prostate cancer; 21.7% of the patients had osteoporosis. The average surgical time was of 47.5 minutes, the average blood loss was of 10 mL. No complications were reported. Conclusion Transpedicular percutaneous biopsy guided by fluoroscopy had an effectiveness of 83% for the etiological diagnosis of vertebral destruction syndrome in the present series. It should be considered a useful minimally-invasive procedure, which is easy, economical, and reproducible, with low risk of short- and long-term complications.


Resumo Objetivo Definir a eficácia da biópsia vertebral percutânea guiada por fluoroscopia. Métodos Este é um estudo prospectivo de pacientes com síndrome de destruição vertebral em uma instituição. Os pacientes foram submetidos a biópsias vertebrais transpediculares percutâneas guiadas por fluoroscopia, com obtenção de tecido ósseo e tecido do disco intervertebral, para estudo histopatológico e microbiológico. Idade, sexo, segmento vertebral, estado neurológico, e resultados de biópsia e de cultura foram analisados. Resultados A idade média dos pacientes foi de 53,8 anos (gama: 2 a 83 anos), e o principal local acometido da coluna foi a segmento lombar, em 62% dos casos. Segundo a escala de disfunção da American Spinal Injury Association (ASIA), no pré-operatório, 49% dos pacientes foram classificados como ASIA E, e 100% apresentavam dor. A etiologia definitiva foi identificada em 83% dos pacientes. A etiologia foi agrupada em três categorias: infecciosa, neoplásica, e degenerativa (osteoporótica). O grupo infeccioso era composto por 36% dos pacientes da amostra, e Staphylococcus aureus foi o agente mais comumente identificado; em 34,9% dos casos, a etiologia era neoplásica, principalmente mieloma múltiplo e doença metastática por câncer de próstata; 21,7% dos pacientes apresentavam osteoporose. O tempo cirúrgico médio foi de 47,5 minutos, e a perda média de sangue foi de 10 mL. Nenhuma complicação foi relatada. Conclusão Nesta série, a biópsia percutânea transpedicular guiada por fluoroscopia teve 83% de eficácia no diagnóstico etiológico da síndrome de destruição vertebral. Este procedimento minimamente invasivo deve ser considerado bom, fácil, barato e reprodutível, com baixo risco de complicações em curto e longo prazos.

ABSTRACT

Resumen Los tumores de tronco encefálico representan alrededor del 10% al 20% de los tumores del sistema nervioso central en niños. El glioma intrínseco difuso es el más frecuente (80% de los casos) de este grupo de tumores, que se caracterizan por la mala evolución y una sobrevida corta. El diagnóstico se puede hacer por resonancia magnética (con espectroscopía) o por biopsia estereotáxica, un método controvertido, que permite el estudio inmunohistoquímico y molecular del tumor. La reflexión moral se focaliza en la indicación de biopsia para pacientes vulnerables y con mal pronóstico. Se analiza la cirugía desde el punto de vista ético, con base en el mejor interés del niño y en la actitud altruista del paciente y su familia.


Abstract Brainstem tumors represent about 10% to 20% of central nervous system tumors in children. Diffuse intrinsic glioma is the most frequent (80% of cases) in this group of tumors, characterized by poor prognosis and short survival. Diagnosis can be made by magnetic resonance (with spectroscopy) or by stereotactic biopsy, a controversial method that allows immunohistochemical and molecular study of the tumor. Moral reflection focuses on the indication of biopsy for vulnerable patients with a poor prognosis. Surgery is analyzed from an ethical point of view based on the best interests of the child and altruistic attitude of patient and family.

ABSTRACT

ABSTRACT Purpose: Incidence and mortality of prostate cancer (PCa) are still increasing in developing countries. Limited access to the health system or more aggressive disease are potential reasons for this. Ethnic and social differences in developed countries seem to make inappropriate to extrapolate data from other centers. We aim to report the epidemiological profile of a PSA-screened population from a cancer center in Brazil. Materials and Methods: We retrospectively selected 9.692 men enrolled in a PCa prevention program, comprising total PSA level and digital rectal examination at the first appointment, associated with complementary tests when necessary. Men aged over 40 years-old were included after shared decision-making process. Prostate biopsy (TRUS) was performed when clinically suspected for PCa. After the diagnosis, patients underwent appropriate treatment. Results: TRUS was performed in 5.5% of men and PCa incidence was 2.6%. Overall ratio between number of patients who needed to be screened in order to diagnose one cancer was 38.9 patients, with 2.1 biopsies performed to diagnose a cancer. Positive predictive value (PPV) of TRUS biopsy in this strategy was 47.2%, varying from 38.5% (<50 years-old) to 60% (>80 years-old). We evidenced 70 patients (27.9%) classified as low risk tumors, 74 (29.5%) as intermediate risk, and 107 (42.6%) as high-risk disease. Conclusions: PSA-screening remains controversial in literature. In front of a huge miscegenated people and considering the big proportion of high-risk PCa, even in young men diagnosed with the disease, it is imperative to inform patients and health providers about these data particularities in Brazil.

ABSTRACT

La linfangiomatosis pulmonar difusa es una enfermedad rara caracterizada por una marcada proliferación y dilatación de los vasos linfáticos en los pulmones, la pleura y el mediastino. Se desconoce la prevalencia, y la etiología no se comprende completamente.Una niña de 22 meses ingresó por poliserositis, con derrame pericárdico y pleural. Requirió pericardiocentesis y avenamiento pleural, y presentó drenaje de quilo (1,5-4 litros/día) sin respuesta al tratamiento médico (ayuno, nutrición parenteral y octreotide). Se realizó biopsia pulmonar. La anatomía patológica mostró hallazgos compatibles con linfangiomatosis difusa pulmonar. Comenzó tratamiento con sirolimus y propanolol, que disminuyeron las pérdidas por el drenaje pleural a la semana. Presentó buena evolución; suspendió aporte de oxígeno y se retiró el drenaje pleural. Se externó al cuarto mes de internación. El diagnóstico temprano de la linfangiomatosis pulmonar difusa es difícil de lograr, pero permite aplicar terapéuticas que evitan la progresión de enfermedad y disminuir la morbimortalida


Diffuse pulmonary lymphangiomatosis is a rare disease characterized by marked proliferation and dilation of lymphatic vessels in the lungs, pleura, and mediastinum. The prevalence is unknown and the etiology is not fully understood.A 22-month-old girl was admitted for polyserositis, with pericardial and pleural effusion. She required pericardiocentesis and pleural drainage, presenting chyle drainage (1.5-4 liters/day) without response to medical treatment (fasting, parenteral nutrition and octreotide). A lung biopsy was performed. The pathological anatomy showed findings compatible with diffuse pulmonary lymphangiomatosis. Treatment with sirolimus and propanolol began, decreasing losses due to pleural drainage one week after treatment. She progressed well, discontinued oxygen supply and pleural drainage was removed, leaving the patient after the fourth month of hospitalization.Early diagnosis of diffuse pulmonary lymphangiomatosis is difficult to achieve, but it allows the application of therapies that prevent disease progression, reducing morbidity and mortality.

ABSTRACT

Introducción: Las adenopatías, linfadenopatías o linfoadenomegalias constituyen causas frecuentes de consulta pediátrica. Estas entidades nosológicas pueden variar desde infecciones benignas transitorias hasta procesos malignos como linfoma, metástasis de tumores y otros. Objetivo: Describir un caso clínico con un síndrome adénico que por las características semiológicas sugería un proceso oncoproliferativo y los resultados de los estudios complementarios confirmaron un proceso infeccioso causado por Toxoplasma gondii. Presentación de caso: Adolescente femenina de 11 años de edad, eutrófica, con antecedentes personales de salud. Ingresó en el Hospital Pediátrico Universitario "William Soler " por presentar aumento de volumen en la región cérvico-lateral derecha. Al examen físico se palpó una adenopatía de aproximadamente 2 x 3 cm de diámetro, dura, inmóvil, no dolorosa, sin signos de inflamación, no adherida a planos profundos; evolutivamente, apareció otra adenopatía en posición cervical derecha baja, de iguales características. Se indicó hemograma, velocidad de sedimentación globular, proteína C reactiva, transaminasas, glicemia, proteínas totales, albúmina, triglicéridos, colesterol, marcadores tumorales, ecografía, rayos X de tórax, serología para detectar anticuerpos anti citomegalovirus, virus de inmunodeficiencia humana y Toxoplasma gondii. Se realizó, además, biopsia para estudio por anatomía patológica y biología molecular. Se concluyó el caso como un síndrome adénico de etiología toxoplásmica. Conclusiones: En pacientes adolescentes con adenopatías cervicales, independientemente de tamaño, tiempo de evolución y consistencia, se debe realizar diagnóstico diferencial por infección por Toxoplasma gondii, teniendo en cuenta que las adenopatías causadas por este parásito pueden tener algunas características similares a las ocasionadas por procesos oncoproliferativos que pueden presentarse a esta edad(AU)


Introduction: Adenopathies, lymphadenopathies or lymphadenomegalies are common causes of pediatric consultation. These nosological entities can range from transient benign infections to malignant processes such as lymphoma, tumor metastases, and others. Objective: Describe a clinical case with an adenic syndrome that from the semiological characteristics suggested an onco-proliferative process and the results of the complementary studies confirmed an infectious process caused by Toxoplasma gondii. Case presentation: 11-year-old female adolescent, eutrophic, with a personal health history. She was admitted at "William Soler" University Pediatric Hospital after presenting volume increase in the right lateral cervical region. An adenopathy of approximately 2 x 3 cm in diameter, hard, motionless, non-painful, with no signs of inflammation, not attached to deep planes was found at the physical examination; in the evolution, another adenopathy appeared in a lower right cervical position, with equal characteristics. Blood counts, globular sedimentation rate, C-reactive protein, transaminases, glycemia, total proteins, albumin, triglycerides, cholesterol, tumor markers, ultrasound, chest x-rays, serology for anti-cytomegalovirus antibodies, human immunodeficiency virus and Toxoplasma gondii tests were indicated. Biopsy was also performed for study by pathological anatomy and molecular biology. The case was concluded as an adenic toxoplasmic syndrome. Conclusions: In adolescent patients with cervical adenopathies, regardless of size, evolution time and consistency, differential diagnosis for Toxoplasma gondii infection should be made, taking into account that adenopathies caused by this parasite may have some characteristics similar to those caused by onco-proliferative processes that may occur at this age(AU)

ABSTRACT

ABSTRACT BACKGROUND: Celiac disease (CD) is an immune-mediated systemic disorder elicited by the ingestion of gluten. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) guidelines published in 2012 suggested a no-biopsy pathway (NBP) for symptomatic children with IgA tissue transglutaminase (TGA-IgA) ≥10x upper limit of normal (ULN). Biopsy confirmation remained mandatory for other cases. OBJECTIVE: This retrospective case note study was aimed at evaluating the adherence to the ESPGHAN 2012 guidelines for diagnosing CD in our unit. METHODS: Forty-three cases with positive TGA-IgA were identified by a laboratory database search from January 2013 to December 2019. 6 of 43 patients were not referred for a confirmation of CD diagnosis. Data was collected on the diagnostic pathways followed, and appropriateness of adherence was compared with the existing ESPGHAN guidelines. RESULTS: A total of 37 cases were included with 35 children diagnosed with CD. 29/35 (83%) were diagnosed via the NBP;15/29 (52%) children did not meet all the criteria required for NBP, but were diagnosed and managed as having CD. 20/35 (57%) children were diagnosed with CD in adherence to the 2012 guidelines. CONCLUSION: The recommended diagnostic guidelines were frequently not implemented; adherence to the guidelines may improve following regular educational sessions. The revised 2020 ESPGHAN guidelines which exclude HLA-DQ2/DQ8 testing would address the issue of diagnosis for the 10/15 NBP cases (with TGA-IgA >10xULN) in our study who did not have HLA testing and were therefore non-adherent to the 2012 diagnostic guidelines. NBP, with the reduced need for endoscopy may be beneficial in resource limited settings.


RESUMO CONTEXTO: A doença celíaca (DC) é uma doença sistêmica imuno-mediada provocada pela ingestão de glúten. As diretrizes da Sociedade Europeia de Gastroenterologia Pediátrica, Hepatologia e Nutrição (ESPGHAN) publicadas em 2012 sugeriram uma via sem biópsia (VSB) para crianças sintomáticas com transglutaminase de tecido IgA (TGA-IgA) ≥10x limite superior do normal (LSN). A confirmação da biópsia permaneceu obrigatória para outros casos. OBJETIVO: Este estudo retrospectivo de dados de caso teve como objetivo avaliar a adesão às diretrizes da ESPGHAN 2012 para o diagnóstico de DC em nossa unidade. MÉTODOS: Quarenta e três casos com TGA-IgA positivo foram identificados por uma pesquisa laboratorial de banco de dados de janeiro de 2013 a dezembro de 2019. Seis de 43 pacientes não foram encaminhados para confirmação do diagnóstico de DC. Os dados foram coletados nas vias diagnósticas seguidas, e a adequação da adesão foi comparada com as diretrizes ESPGHAN existentes. RESULTADOS: Foram incluídos 37 casos com 35 crianças diagnosticadas com DC. Foram diagnosticados 29 (83%) de 35 VSB; 15 (52%) de 29 crianças não atenderam a todos os critérios exigidos para a VSB, mas foram diagnosticadas e gerenciadas como tendo DC. Vinte (57%) em 35 foram diagnosticadas com DC em adesão às diretrizes de 2012. CONCLUSÃO: As diretrizes diagnósticas recomendadas não foram frequentemente implementadas; a adesão às diretrizes pode melhorar após sessões educativas regulares. As diretrizes revisadas ESPGHAN de 2020 que excluem os testes HLA-DQ2/DQ8 abordariam a questão do diagnóstico para 10 em 15 casos VSB (com TGA-IgA >10x LSN) em nosso estudo os quais não fizeram testes de HLA e, portanto, não aderiram às diretrizes de diagnóstico de 2012. A VSB, com a necessidade reduzida de endoscopia, pode ser benéfica em configurações limitadas de recursos.

ABSTRACT

ABSTRACT BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the most prevalent liver disease in the world, and its prevalence is increasing alongside obesity. In United States, NAFLD is already the second leading cause of liver transplantation. The spectrum of the disease ranges from simple steatosis, which has a benign course, to steatohepatitis, which may progress to cirrhosis and its complications. The rising of noninvasive methods for diagnosing and staging non-alcoholic steatohepatitis (NASH) and fibrosis decreases the need of liver biopsy, as well as the costs and the occurrence of complications related to it. OBJECTIVE: To analyze the performance of the triglyceride-glucose index to evaluate steatosis, NASH and liver fibrosis in obese patients with NAFLD. METHODS: This is a retrospective cross-sectional study. Every medical record of patients who were candidates for bariatric surgery at a leading hospital in Southern Brazil were analyzed. The triglyceride-glucose index (TyG Index), a method composed only of two simple laboratory tests (serum triglycerides and fasting glucose levels), was performed prior to surgery. The TyG Index performance regarding the anatomopathological findings was evaluated, and the AUROC curve was calculated to evaluate the best cut-off point for diagnosing steatosis, non-alcoholic steatohepatitis and liver fibrosis grade. Also, the NAFLD fibrosis Score (NFS) was evaluated. RESULTS: A total of 423 patients were evaluated. The TyG Index with a cut-off point of 8.76 excluded significant simple steatosis (grade 2-3) in obese patients, with 67.6% sensitivity, 65.1% specificity, 46.3% positive predictive value (PPV), 81.8% negative predictive value (NPV), 65.8% accuracy and 0.66 AUROC (P=0.005). In the evaluation of NASH, the TyG Index with a cut-off point of 8.82 excluded significant NASH (grade 2-3) with 57.3% sensitivity, 58.6% specificity, 33.7% PPV, 78.8% NPV, 58.2% accuracy and 0.58 AUROC (P=0.022). When evaluating liver fibrosis, the TyG Index with a cut-off point of 8.91 showed a sensitivity of 61.8%, a specificity of 62.5%, a PPV of 13.8 and a NPV of 94.4% for exclusion of advanced fibrosis (F3-4), with a 62.4% accuracy and 0.69 AUROC (P<0.001). When analyzing the performance of NFS in the diagnosis of advanced fibrosis, the cut-off point <-1.455 excluded advanced fibrosis with sensitivity of 59.4%, specificity of 51%, PPV of 11%, NPV of 92.4% and accuracy of 51.7%. However, the cut-off point of 0.676 to diagnose advanced fibrosis presented sensitivity of 21.9%, specificity of 83%, PPV of 11.7%, NPV of 91.2% and 77.3% accuracy. The AUROC was 0.54 (P=0.480). CONCLUSION: TyG Index did not perform well in the diagnosis of significant steatosis and NASH. However, it was able to exclude advanced fibrosis in obese patients who are candidates for bariatric surgery.


RESUMO CONTEXTO: A doença hepática gordurosa não-alcoólica (DHGNA) é a doença hepática mais prevalente no mundo. Nos Estados Unidos, a DHGNA já é a segunda causa de transplante hepático. O espectro da doença abrange desde a esteatose simples, que apresenta curso benigno, até esteato-hepatite não-alcoólica (EHNA), que pode progredir para cirrose e suas complicações. O desenvolvimento de métodos não invasivos para o diagnóstico e estadiamento da EHNA e da fibrose hepática visa diminuir a necessidade de biópsia hepática, um procedimento invasivo e não raro associado a complicações. OBJETIVO: Analisar o desempenho do índice triglicerídeo-glicose (TyG Index) para o diagnóstico e estadiamento da DHGNA em pacientes obesos. MÉTODOS: Este é um estudo transversal retrospectivo. Foram analisados todos os prontuários de pacientes candidatos a cirurgia bariátrica em um hospital de referência do Sul do Brasil e calculado o TyG Index, um escore composto por dois exames laboratoriais (triglicerídeos e glicose de jejum), realizados previamente à cirurgia. O desempenho do TyG Index em relação aos achados anatomopatológicos hepáticos foi avaliado, e calculada a curva ROC para avaliação de esteatose simples, EHNA e fibrose hepática. O NAFLD Fibrosis Score (NFS) também foi avaliado. RESULTADOS: Foram avaliados 423 pacientes. O melhor ponto de corte do TyG Index para a exclusão de esteatose simples significativa (grau 2-3) foi de 8,76, com sensibilidade 67,6%, especificidade 65,1%, valor preditivo positivo (VPP) 46,3%, valor preditivo negativo (VPN) 81,8%, acurácia 65,8% e AUROC 0,66 (P=0,005). Na avaliação de EHNA significativa (grau 2-3), o melhor ponto de corte foi de 8,82 com sensibilidade 57,3%, especificidade 58,6%, VPP 33,7%, VPN 78,8%, acurácia 58,8% e AUROC 0,58 (P=0,022). Em relação à fibrose avançada (grau 3-4), o melhor ponto de corte do TyG Index foi de 8,91 com sensibilidade 61,8%, especificidade 62,5%, VPP 13,8%, VPN 94,4%, acurácia 62,4% e AUROC 0,69 (P<0,001). Ao analisarmos o desempenho do NFS no diagnóstico de fibrose avançada, o ponto de corte de <-1,455 excluiu fibrose avançada com sensibilidade 59,4%, especificidade 51%, VPP 11%, VPN 92,4% e acurácia 51,7%. Entretanto, o ponto de corte de 0,676 para fibrose avançada apresentou sensibilidade de 21,9%, especificidade 83%, VPP 11,7%, VPN 91,2% e acurácia 77,3%. A AUROC foi de 0,54 (P=0,480). CONCLUSÃO: O TyG Index não apresentou bom desempenho para o diagnóstico e estadiamento da esteatose simples e da EHNA. Entretanto, foi capaz de excluir fibrose avançada em pacientes obesos candidatos a cirurgia bariátrica.

ABSTRACT

INTRODUCCIÓN. La fosa pterigopalatina es una zona anatómica de difícil acceso, que al presentar masas tumorales genera un alto riesgo de morbimortalidad en población juvenil y adulta, que precisa determinar las complicaciones asociadas a cirugía. OBJETIVO. Evaluar los tipos de abordaje quirúrgico, complicaciones e identificar la estirpe histológica de los tumores de fosa pte-rigopalatina. MATERIALES Y MÉTODOS. Estudio transversal retrospectivo. Población y muestra conocida de 29 Historias Clínicas de pacientes con hallazgos de imagen e histopatológico de tumores con invasión a fosa pterigopalatina divididos en dos grupos: A) resección de masa tumoral y B) biopsia de masa tumoral, operados en el Hospital de Especialidades Carlos Andrade Marín en el período de enero 2017 a diciembre de 2020. RESULTADOS. El 82,76% (24; 29) fueron hombres, con promedio de edad de 30,6 años. El 82,76% (24; 29) de las masas tumorales se originaron en nasofaringe; no se reportaron casos primarios. El tumor más frecuente fue el Angio-fibroma Nasofaringeo Juvenil 68,97% (20; 29), seguido por los tumores malignos con el 20,69% (6; 29), siendo usual el carcinoma adenoideo quístico. En el 62,07% (18; 29) el tumor invadió Fosa Infratemporal y en el 44,83% (13; 29) hacia esfenoides. En el grupo A, el abordaje quirúrgico empleado en el 20,83% (5; 24) fue mediante técnica abierta y en el 79,17% (19; 24) con técnica endoscópica, tanto uni 31,58% (6; 19) como multiportal 68,42% (13; 19). La complicación fue la hiposensibilidad facial en el 12,5% (3; 24), todos en abordajes abiertos. CONCLUSIÓN. Se evaluó los tipos abordaje quirúrgico y se identificó la estirpe histológica de los tumores de fosa pterigopalatina


INTRODUCTION. The pterygopalatine fossa is an anatomical area of difficult access, which when presenting tumor masses generates a high risk of morbimortality in the juvenile and adult popula-tion, which needs to determine the complications associated with surgery. OBJECTIVE. To eva-luate the types of surgical approach, complications and identify the histologic type of pterygopala-tine fossa tumors. MATERIALS AND METHODS. Retrospective cross-sectional study. Population and known sample of 29 Clinical Histories of patients with imaging and histopathological findings of tumors with invasion to pterygopalatine fossa divided into two groups: A) resection of tumor mass and B) biopsy of tumor mass, operated at the Carlos Andrade Marín Specialty Hospital in the period from january 2017 to december 2020. RESULTS. The 82,76% (24; 29) were men, with an average age of 30,6 years. 82,76% (24; 29) of the tumor masses originated in nasopharynx; no primary cases were reported. The most frequent tumor was juvenile nasopharyngeal angiofibroma 68,97% (20; 29), followed by malignant tumors with 20,69% (6; 29), being usual the adenoid cystic carcinoma. In 62,07% (18; 29) the tumor invaded the Infratemporal Fossa and in 44,83% (13; 29) into the sphenoid. In group A, the surgical approach used in 20,83% (5; 24) was by open technique and in 79,17% (19; 24) by endoscopic technique, both uni 31,58% (6; 19) and multiportal 68,42% (13; 19). The complication was facial hyposensitivity in 12,5% (3; 24), all in open approaches. CONCLUSION. The types of surgical approach were evaluated and the histologic type of pterygo-palatine fossa tumors was identified.

ABSTRACT

Abstract We present a rare case of hypertrophic gastropathy associated with protein loss. A 35-year-old man was hospitalized for bowel habit changes, abdominal pain, generalized edema and symptomatic anemia. Pertinent laboratory findings included iron deficiency anemia (Hb 6.7g/dl, ferritin 5 ng/ml) and marked hypoalbuminemia (albumin 2.5 g/dl). Endoscopic biopsy samples of giant gastric folds observed along the greater gastric curvature revealed foveolar hyperplasia and significant parietal cell loss. Endoscopic ultrasonography showed gastric parietal thickening with preserved architecture and normal gastric wall layers. Menetrier disease was diagnosed and the patient treated with cetuximab, a monoclonal antibody that inhibits ligand binding of trans forming growth factor alpha (TGFa), preventing gastric mucosa cell proliferation. After twelve months of treatment, the patient referred symptoms improvement, and gastric biopsy levels of the proliferation marker protein Ki-67 had decreased.


Resumen Presentamos un caso infrecuente de gastropatía hipertrófica asociada a pérdida de proteínas. Un hombre de 35 años fue hos pitalizado por cambios en los hábitos intestinales, dolor abdominal, edema generalizado y anemia sintomática. Los hallazgos de laboratorio pertinentes incluyeron anemia ferropénica (Hb 6.7 g/dl, ferritina 5 ng/ml) e hipoal buminemia marcada (albúmina 2.5 g/dl). Las muestras de biopsia endoscópica de pliegues gástricos gigantes observados a lo largo de la curvatura mayor gástrica revelaron hiperplasia foveolar y pérdida significativa de células parietales. La ecografía endoscópica mostró engrosamiento parietal gástrico con arquitectura conservada y capas de pared gástrica normales. Se diagnosticó enfermedad de Menetrier y se trató al paciente con cetuximab, un anticuerpo monoclonal que inhibe la unión del ligando del factor de crecimiento transformante alfa (TGFa), evitando la proliferación de células de la mucosa gástrica. Después de doce meses de tratamiento, el paciente refirió mejoría de los síntomas y los niveles de la proteína marcadora de proliferación Ki-67 en biopsia gástrica habían disminuido.

ABSTRACT

Objetivo: el objetivo de este estudio es describir y presentar el tratamiento para los granulomas gigantocelulares centrales con múltiples recidivas. Caso clínico: paciente femenina de 14 años que presenta granuloma gigantocelular central en maxilar inferior izquierdo, con múltiples recidivas luego del curetaje del mismo. Clínicamente se observa aumento de tamaño, desplazamiento dentario y, radiográficamente, una gran zona radiolúcida compatible con pérdida ósea. Se realizó la resección de la lesión en bloque con margen de seguridad, conservando la basal mandibular con colocación de placa de osteosíntesis de carga soportada. Conclusiones: el granuloma gigantocelular central es una lesión osteolítica, generalmente de crecimiento lento, asintomático y no agresivo. El tratamiento quirúrgico de resección con márgenes de seguridad es fundamental debido a su gran potencial de recidiva (AU)

ABSTRACT

Se presenta el caso de un paciente de 47 años quien consultó por cuadro de cicatrización tórpida de una lesión cutánea superficial única en hemi-escroto izquierdo. Se procedió a resección biópsica de la lesión con resultado de la anatomía patológica de un Carcinoma Escamoso del tipo Condilomatoso (Warty) el cual confirma su relación con el HPV 16 mediante estudio de inmunohistoquímica. Por ser un caso infrecuente no existe actualmente un consenso sobre el manejo del carcinoma del escroto motivo el cual se realiza una revisión de la literatura y se expone los resultados.


A case of a 47-year-old patient who consulted for torpid healing of skin lesion in left hemi-scrotum is presented. We proceed to resection-biopsy of the lesion and the pathology report informed a warty squamous cell carcinoma (Warty type) and the relationship with HPV 16 is confirmed by immunohistochemical study. As a rare case there is currently no consensus on the management of carcinoma of the scrotum reason that we do a review of the literature and the results are exposed.

ABSTRACT

Objetivo: Analizar y describir los requerimientos de atención quirúrgica bucomaxilofacial de urgencia en el Servicio de Urgencias Odontológicas y Orientación de Pacientes de la Facultad de Odontología de la Universidad de Buenos Aires durante el aislamiento social preventivo y obligatorio por la pandemia de COVID-19. Materiales y métodos: Se realizó un estudio observacional descriptivo de análisis retrospectivo durante el período de aislamiento social preventivo y obligatorio inicial de 93 días, comprendido entre el 20 de marzo y el 20 de junio de 2020. Se evaluó la totalidad de historias clínicas de los pacientes que acudieron al Servicio de Urgencias Odontológicas y Orientación de Pacientes de la Facultad de Odontología de la Universidad de Buenos Aires y se caracterizó a aquellos que requerían distintos tipos de tratamiento quirúrgico bucal y maxilofacial. Resultados: Durante el período estudiado, se atendieron 4564 pacientes, de los cuales 1337 (29,3%) requirieron tratamientos quirúrgicos como terapéutica para la resolución de la urgencia. De estos, el 93,2% fueron exodoncias de piezas erupcionadas o retenidas; el 1,7%, biopsias quirúrgicas; el 2,4%, tratamientos agudos de infecciones que involucran espacios anatómicos vecinos; el 0,8%, resolución de traumatismos en los maxilares, y el 1,9%, tratamientos de complicaciones posquirúrgicas. Conclusión: Los resultados ponen de relieve la necesidad de disponer de servicios de guardia odontológica en el ámbito del AMBA que cuenten con recursos humanos calificados y entrenados para resolver urgencias de tipo quirúrgico


Aim: The objective of this study was to analyze and describe the requirements for the emergency care of oral and maxillofacial surgical treatment in the emergency dental department of the School of Dentistry of the University of Buenos Aires during the Preventive and Mandatory Social Isolation. Materials and methods: We conducted a retrospective analysis of a descriptive observational study during the initial period of 93 days of Preventive and Compulsory Social Isolation, from March 20, 2020 to June 20, 2020. All the medical records of the patients who attended the emergency dental department of the School of Dentistry of the University of Buenos Aires were evaluated and those who required different types of oral and maxillofacial surgical treatment were characterized. Results: A total of 4564 patients were attended during the period studied, of which 1337 (29.3%) required surgical treatment as a therapy for the resolution of their emergencies. Of these, 93.2% were exodontia of erupted or retained teeth, 1.7% surgical biopsies, 2.4% acute treatment of infections involving neighboring anatomical spaces, 0.8% resolution of maxillary alveolar trauma and 1.9% treatment of post-surgical complications. Conclusion: The results highlight the need to have dental emergency services in the AMBA area that have qualified and trained human resources to solve the surgical type emergencies that may arise (AU)

ABSTRACT

Objetivo: Los desórdenes de mucosa bucal potencialmente malignos pueden presentar áreas displásicas. En estos casos, la biopsia es un procedimiento imprescindible para un correcto diagnóstico. La inspección visual y la palpación, como método de selección del área de biopsia, ofrecen sensibilidad y especificidad adecuadas pero mejorables. El objetivo de este artículo es presentar una serie de casos clínicos en los que se describen el empleo y la interpretación de la tinción vital con azul de toluidina como método complementario para contribuir a una mejor elección del área de biopsia. Casos clínicos: Se trata de siete casos de lesiones con sospecha de displasia epitelial en mucosa bucal. En cada uno se detalla la correlación de las áreas teñidas con las manifestaciones clínicas y con el diagnóstico de displasia. Además, se muestran patrones de tinción considerados falsos positivos. En la interpretación de la tinción positiva, se tuvieron en cuenta el aspecto superficial y el color de la lesión teñida. El empleo combinado de inspección, palpación y tinción vital podría constituir un procedimiento integral de utilidad para obtener mayor precisión en la determinación del sitio de biopsia en comparación con los mismos procedimientos aplicados de manera individual. En la interpretación de la tinción positiva con azul de toluidina deberían considerarse el aspecto superficial y el color de la lesión teñida (AU)


Aim: Potentially Malignant Disorders in the oral cavity can present dysplastic areas. In these cases, the biopsy is an essential procedure for a correct diagnosis. Visual inspection and palpation, are adequate methods to select the area for the biopsy, however there is margin for improvement. The objective of this article is to present a series of clinical cases in which the use and interpretation of vital staining with Toluidine Blue is described as a complementary method to contribute to a better choice of the biopsy area. Clinical cases: Seven clinical cases that presented lesions with suspected epithelial dysplasia in the oral mucosa were presented. The correlation of the stained areas with the clinical manifestations and with the diagnosis of dysplasia is detailed in each case. Staining patterns considered false positives are also shown. In the interpretation of the positive staining, the superficial appearance and color of the stained lesion were considered. The combined use of inspection, palpation and vital staining could constitute a useful comprehensive procedure to obtain greater precision in determining the biopsy site in relation to the same procedures applied individually. In the interpretation of the positive staining with Toluidine Blue, the superficial appearance and color of the stained lesion should be considered (AU)

ABSTRACT

Objetivo: Describir el diagnóstico y el tratamiento interdisciplinario de un caso clínico de histoplasmosis. Caso clínico: Un paciente masculino de 39 años, con antecedentes de consumo de drogas, alcohol, tabaquismo crónico y VIH+ sin adherencia al tratamiento, acudió al Servicio de Odontología por una interconsulta del Servicio de Clínica Médica para la evaluación de lesiones erosivas en paladar duro y blando, reborde alveolar anterior, dorso lingual y lesión tumoral en encía anterosuperior. El diagnóstico definitivo se obtuvo por medio del análisis de muestras de biopsia transbronquial, lavado broncoalveolar y biopsia de lesión en piel. El paciente recibió tratamiento sistémico con antimicóticos (anfotericina B e itraconazol según esquema) y tratamiento local con colutorio de clorhexidina al 0,12% y 100.000 UI de nistatina en suspensión. Al momento del alta, presentaba una considerable mejoría de su estado general y de las lesiones orales, con disminución de sintomatología dolorosa. Se indicó turno para control a los 7 días de forma ambulatoria, al cual el paciente no asistió. El abordaje interdisciplinario y el análisis de los diferentes aspectos socioeconómicos, culturales, ambientales y sistémicos del paciente facilitaron el diagnóstico temprano de la enfermedad (AU)


Aim: To describe the diagnosis and interdisciplinary treatment of a clinical case of histoplasmosis. Clinical case: 39-year-old male patient with a history of drug abuse, alcohol, and chronic smoking, HIV+ without treatment compliance, attends the dental department referred by the medical department for the diagnosis of erosive lesions in the hard and soft palate, anterior alveolar ridge, lingual dorsum and tumor lesion in the anterosuperior gingiva. The definitive diagnosis was obtained by the analysis of transbronchial biopsy, bronchoalveolar lavage and skin lesion biopsy. The patient received systemic treatment with antifungals (amphotericin b, itraconazole according to protocol), and local treatment with 0.12% chlorhexidine mouthwash and 100,000 IU nystatin suspension. At the time of medical discharge, the patient presented a considerable improvement in his general condition and of the oral lesions with a reduced pain. A 7 days recall was prescribed, however the patient failed to attend. The interdisciplinary approach to the patient and the analysis of the different socio-economic, cultural, environmental and systemic aspects of the patient facilitates the early diagnosis of the disease (AU)

ABSTRACT

El tumor sólido pseudopapilar del páncreas, conocido también como tumor de Frantz, es una enfermedad rara: neoplasia bien delimitada, de lento crecimiento, no agresiva pero maligna, habitualmente con pronóstico favorable. El tratamiento de elección es quirúrgico. Aunque algunos de ellos son agresivos a nivel local, la mayoría de los pacientes se curan con la resección completa del tumor. Se reportó el caso de una mujer de 30 años, ingresada en el Servicio de Cirugía General del Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández, con diagnóstico presuntivo clínico e imagenológico, de tumor pseudopapilar sólido del páncreas, con confirmación histológica tras la resección quirúrgica. Este infrecuente tumor debe ser considerado en el diagnóstico diferencial de los tumores pancreáticos, fundamentalmente en mujeres jóvenes(AU)


The solid pseudo-papillary carcinoma, also known as Frantz´s tumor, is a rare disease. It is a well-defined neoplasia, of low growth, non-aggressive but malignant, usually with a favorable prognosis. The elective treatment is the surgery. Although some of them are locally aggressive, most patients are healed with the complete tumor resection. The authors reported the case of a woman, aged 30 years who entered the Service of General Surgery of the University Hospital Comandante Faustino Pérez Hernández, with a presumptive clinical and imaging diagnosis of pancreas solid pseudo-papillary tumor, histologically confirmed after surgical resection. This infrequent tumor should be taken into account in the differential diagnosis of pancreatic tumors, mainly in young women(AU)

ABSTRACT

El melanoma subungueal es un subgrupo del melanoma acral lentiginoso. Con frecuencia se diagnostica en etapa avanzada, dada la escasez de síntomas; de ahí que la evaluación y el tratamiento oportuno mejoran el pronóstico. Se presenta el caso de un paciente de 44 años de edad, que acude a consulta de Ortopedia con melanoniquia de tres meses de evolución. Había sido tratado en la atención primaria de salud por un hematoma secundario a un trauma directo sobre la falange distal del primer artejo del pie izquierdo. Fue seguido por consulta externa de Ortopedia y, al no experimentar una evolución adecuada, fue evaluado por la Comisión Provincial de Tumores Periféricos. Se le realizó una biopsia por punch (sacabocado), que arrojó el resultado de melanoma subungueal. Se realizó la amputación del primer artejo y del proximal del primer metatarsiano, una vez verificada la no existencia de lesiones metastásicas, con excelente resultado estético y funcional, sin mostrar recidiva en su seguimiento, a dos años de su intervención(AU)


Subungual melanoma is a subgroup of lentiginous acral melanoma. It is often diagnosed in an advanced stage by a shortage of symptoms, so timely evaluation and treatment improve prognosis. This is the case of a 44-year-old patient who goes to orthopedics with melanonichia 3 months of evolution. He had been treated for a bruise secondary to direct trauma to the distal phalanx of the first left foot ailre in primary health care. It was followed by external orthopedic consultation and by not following an adequate evolution was evaluated by the provincial commission of peripheral tumors. He was given a punch biopsy resulting in a subungual melanoma. The amputation of the first artejo and proximal first metatarsal was carried out, once verified the non-existence of metastatic lesions, with excellent aesthetic and functional result, without showing relapse in its follow-up to two years(AU)
