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

Se realizó un estudio con diseño cuantitativo, de tipo observacional descriptivo; cuya población de estudio estuvo constituida por 142 pacientes de sexo femenino, diagnosticadas con cáncer de mama en la Unidad Oncológica Solca-Chimborazo, durante el período 2014-2019; con el objeti - vo de describir el tratamiento fisioterapéutico en ese contexto de investigación. Los datos fueron recolectados a partir de las respectivas historias clínicas. A partir de 2015, se observó un predo- minio de pacientes adultos con edades comprendidas entre 36 y 65 años. De las 142 pacientes que conformaron la población estudiada, solo 5 desarrollaron linfedema posquirúrgico. La mayoría de las pacientes incluidas en el estudio fueron intervenidas quirúrgicamente (65); 59 de las cuales recibieron tratamiento de drenaje linfático manual. Entre la población elegida en la Unidad Oncológica de Solca-Chimborazo se evidenció que la aplicación de terapia de rehabili - tación mediante drenaje linfático manual posquirúrgico reduce la posibilidad de aparición de linfedema a largo plazo.


This research aimed to describe the physiotherapeutic treatment in this research context. A study was carried out with a quantitative design, of a descriptive observational type. The study popula- tion consisted of 142 female patients, diagnosed with breast cancer at the Solca-Chimborazo Oncology Unit, during the period 2014-2019. The data were collected from the respective medi- cal records. Since 2015, a predominance of adult patients aged between 36 and 65 years was observed. From the 142 patients that made up the study population, only 5 developed postsurgi- cal lymphedema. Most of the patients included in the study underwent surgery (65); 59 received manual lymphatic drainage treatment. Among the population chosen in the Solca-Chimborazo Oncology Unit, it was evidenced that the application of rehabilitation therapy through postope- rative manual lymphatic drainage reduces the possibility of long-term lymphedema develop - ment.

ABSTRACT

Apesar de fibroadenoma ser uma das lesões mais comuns da mama, sua correlação a alteração maligna é rara.1,2,3,5,7 Quando ocorre tem apresentação clínica similar a dos fibroadenomas típicos, diagnóstico anatomopatológico em geral pós-cirúrgico e tratamento conforme do carcinoma do mesmo tipo histológico isolado.1,2,3,4,6 Apresentamos caso de mulher de 52 anos, apresentando em propedêutica investigativa nódulo em mama direita. Core-biopsy sugeriu carcinoma ductal in situ desenvolvido dentro de fibroadenoma, confirmado em análise anatomopatológica pósoperatória. Tratamento e seguimento se deu conforme já estabelecido pela literatura para carcinoma in situ. Devido baixa incidência, há poucas evidências científicas quanto ao diagnóstico, tratamento e prognóstico desse tipo de lesão. Portanto, apresentar à comunidade científica casos de carcinoma inclusos a fibroadenoma se faz relevante.


Although fibroadenoma is one of the most common lesions of the breast, its correlation with malignant changes is rare. When it occurs, the clinical presentation is similar to typical fibroadenomas, anatomopathological diagnosis is after surgery and treatment goes according to the carcinoma histological type. A case of a 52-year-old woman is presented, with an impalpable nodule in the right breast, diagnosed from screening exams. Corebiopsy suggested carcinoma ductal in situ developed within fibroadenoma, confirmed in the postoperative anatomopathological analysis. Treatment and follow-up followed as established in the literature for carcinoma in situ. Due the low incidence, there are poor scientific evidence regarding the diagnosis, treatment and prognosis of this type of injury. Therefore, presenting cases of Carcinoma ductal in situ arising in a fibroadenoma to the scientific community is so relevant.

ABSTRACT

BACKGROUND@#The current deep learning diagnosis of breast masses is mainly reflected by the diagnosis of benign and malignant lesions. In China, breast masses are divided into four categories according to the treatment method: inflammatory masses, adenosis, benign tumors, and malignant tumors. These categorizations are important for guiding clinical treatment. In this study, we aimed to develop a convolutional neural network (CNN) for classification of these four breast mass types using ultrasound (US) images.@*METHODS@#Taking breast biopsy or pathological examinations as the reference standard, CNNs were used to establish models for the four-way classification of 3623 breast cancer patients from 13 centers. The patients were randomly divided into training and test groups (n = 1810 vs. n = 1813). Separate models were created for two-dimensional (2D) images only, 2D and color Doppler flow imaging (2D-CDFI), and 2D-CDFI and pulsed wave Doppler (2D-CDFI-PW) images. The performance of these three models was compared using sensitivity, specificity, area under receiver operating characteristic curve (AUC), positive (PPV) and negative predictive values (NPV), positive (LR+) and negative likelihood ratios (LR-), and the performance of the 2D model was further compared between masses of different sizes with above statistical indicators, between images from different hospitals with AUC, and with the performance of 37 radiologists.@*RESULTS@#The accuracies of the 2D, 2D-CDFI, and 2D-CDFI-PW models on the test set were 87.9%, 89.2%, and 88.7%, respectively. The AUCs for classification of benign tumors, malignant tumors, inflammatory masses, and adenosis were 0.90, 0.91, 0.90, and 0.89, respectively (95% confidence intervals [CIs], 0.87-0.91, 0.89-0.92, 0.87-0.91, and 0.86-0.90). The 2D-CDFI model showed better accuracy (89.2%) on the test set than the 2D (87.9%) and 2D-CDFI-PW (88.7%) models. The 2D model showed accuracy of 81.7% on breast masses ≤1 cm and 82.3% on breast masses >1 cm; there was a significant difference between the two groups (P < 0.001). The accuracy of the CNN classifications for the test set (89.2%) was significantly higher than that of all the radiologists (30%).@*CONCLUSIONS@#The CNN may have high accuracy for classification of US images of breast masses and perform significantly better than human radiologists.@*TRIAL REGISTRATION@#Chictr.org, ChiCTR1900021375; http://www.chictr.org.cn/showproj.aspx?proj=33139.

ABSTRACT

La mastitis granulomatosa es una enfermedad rara, de etiología desconocida y de diagnóstico de exclusión luego de descartar otras causas de mastitis, como las asociadas a infecciones bacterianas y a gérmenes atípicos como hongos y tuberculosis. La incidencia ha sido difícil de determinar, pero varia del 0.3% al 1.8%. Más frecuente en mujeres en edad reproductiva, la presentación clínica más común de este tipo de mastitis es una masa mamaria de consistencia dura, unilateral, asociada a dolor, eritema, calor e hinchazón, sin fiebre. Tiende a formar abscesos únicos o múltiples con fistulización, lo que hace que se confunda con carcinoma inflamatorio o localmente avanzado. Además, tiende a ser recurrente. El diagnóstico solo puede confirmarse por histopatología, en la que se evidencian granulomas no caseificantes concentrados en lobulillos mamarios, con infiltrado linfocitario crónico, necrosis y, con frecuencia, ectasia ductal. El tratamiento es controvertido, con opciones que van desde la observación, antibióticoterapia, terapia con corticosteroides, medicamentos inmunosupresores como el metotrexato, a la cirugía con escisión local amplia.


Granulomatous mastitis is a rare disease of unknown etiology, and the diagnosis is of exclusion after ruling out other causes of mastitis such as those associated with bacterial infectious diseases and by atypical germs such as fungi and tuberculosis. the incidence has been difficult to determine but varies from 0.3 to 1.8%. More common in women of reproductive age, the most common clinical presentation is a breast mass of hard, unilateral consistency, associated with pain, erythema, heat, swelling, and without fever. It tends to form single or multiple abscesses with fistulization, which makes it possible to be confused with an inflammatory or locally advanced carcinoma. Also with tendency to recurrence. The diagnosis can only be confirmed by histopathology, it is characterized by non-caseifying granulomas concentrated in breast lobules with chronic lymphocyte infiltrate, necrosis and often ductal ectasia. The treatment is controversial, with options ranging from observation, antibiotic therapy, corticosteroid therapy, immunosuppressive medications such as methotrexate, to surgery such as wide local excision.

ABSTRACT

Introducción: ¿La mastoplastia de aumento realizada por un cirujano no especialista en cirugía plástica debe ser vista como un acto de intrusismo o de competencia médica? Objetivo: Presentación de casos de mastoplastias de aumento realizadas por un ginecólogo mastólogo, su comparación con la bibliografía publicada por reconocidos cirujanos plásticos y discusión de la situación actual del tema. Material y método: Se describen retrospectivamente casos de mastoplastia de aumeeto recolectados en diez años de experiencia unipersonal, entre julio 2010 y abril de 2020, comparando resultados cosméticos y complicaciones con casuística publicada. Resultados: Se realizaron 144 casos de mastoplastia de aumento. Hubo 2.08% de complicaciones tempranas y 6.25% de complicaciones tardías, con 94.4% de satisfacción cosmética de las pacientes. No hubo diferencias significativas respecto a tasa de complicaciones quirúrgicas respecto a la serie comparada, encontrando equivalente el resultado cosmético. Conclusiones: La mastoplastia de aumento realizada por un cirujano mastólogo capacitado en el área cosmética, debería aceptarse dentro del alcance de su competencia, creando un marco regulatorio científico y legal adecuado.


Introduction: Can an augmentation mammoplasty performed by a surgeon who is not a plastic surgery specialist be cosidered as an act of presessional intusion, or within the scope of his competence? Objetive: Report of a gynecologist and breast specialist's experience comparing results and complications to the reported case studies published by renowned plastic surgeons and an argument about the topic. Material and method: The author reports retrospectively his ten years experience (january 2010 - april 2020) in augmentation mammoplasty. Cosmetic results and complications were compared with published reports. Results: 144 augmentation mammoplasties were performed between january 2010 and april 2020. There were 2.08% of early complications, 6.25% of late complication, and 94.4% of the patients were satisfied with the cosmetic result. The results show no significative difference about complications and an equivalent cosmetic satisfaction compared to the reported experience published. Conclusions: Augmentation mammoplasty surgery performed by a breast surgeon trained in cosmetic procedures must be considered within the scope of his competence, thus developing an adequate medical and legal regulatory framework.

ABSTRACT

Resumen Objetivo: Establecer la prevalencia de mujeres mayores de 50 años con mamas densas estudiadas por mamografía en el área de Bucaramanga. Métodos: Se realizó un estudio descriptivo retrospectivo durante el periodo comprendido entre enero de 2014 y agosto de 2015, en el que se revisaron 10.110 mamografías de pacientes mayores de 50 años. Posteriormente, se hizo una revisión de la literatura en las principales bases de datos. Resultados: De las 10.110 mamografías realizadas, 4.448 fueron encontradas como positivas para mama densa. De estas, el 39,69% correspondió a tejido mamario heterogéneamente denso y el 4,29%, a tejido mamario extremadamente denso, para un total de 43,9% de los casos estudiados. Conclusión: La densidad mamaria es un factor de riesgo independiente de cáncer de mama, considerado de mediana importancia frente a otros factores. A medida que incrementa la densidad mamaria, se genera la superposición del tejido mamario radio-opaco que puede ocultar y llegar a retardar el diagnóstico de un cáncer subyacente. Dada la alta prevalencia de tejido mamario denso encontrado en la población estudiada, se sugiere complementar el tamizaje con otros métodos de imágenes.


Abstract Objective: To establish the prevalence of dense breast tissue in a group of women aged over 50 years, who were studied with mammography in the city of Bucaramanga (Colombia). Methods: A retrospective descriptive study was conducted from January 2014 to August 2015; 10.110 mammograms of patients aged over 50 years were reviewed. Subsequently, a review of the literature in the main databases was made. Results: From 10.110 mammograms that were performed, 4.448 were found to be positive for dense breast tissue. 39,69% had heterogeneously dense breast tissue, and 4,29% extremely dense breast tissue, for a total result of 43,9% patients with positive dense breast tissue. Conclusion: Breast density is an independent risk factor for breast cancer, being of medium importance compared with other factors. As the breast density increases, the overlap of the radiopaque breast tissue that can hide and delay the diagnosis of an underlying cancer is generated. The high prevalence of dense breast tissue that we found in this population suggests the need of complementing screening with other imaging methods.

ABSTRACT

La Inteligencia Artificial (IA), si bien ha generado gran interés en los últimos cinco años en el campo de la Medicina, no podemos aseverar que se trate de un concepto nuevo, ya que, desde la década del 1940 se publican artículos sobre la materia. La primera vez que tuve ocasión de tomar conocimiento sobre el gran potencial que residía en una computadora fue en mayo de 1997, cuando me encontraba cursando el segundo año de la residencia en Ginecología. Fue una sorpresa leer en el periódico que la máquina llamada "Deep Blue", desarrollada por IBM (International Business Machines), había ganado una competencia virtual de ajedrez al entonces campeón mundial de ajedrez, Garry Kasparov

ABSTRACT

ABSTRACT BACKGROUND: The largest radiological accident to occur in any urban area happened in Goiânia, Brazil, in 1987. OBJECTIVE: To evaluate the association between breast cancer incidence and ionizing radiation levels. DESIGN AND SETTING: Ecological study among residents of the city of Goiânia, Brazil. METHODS: The central region of Goiânia, with seven major sources of contamination from cesium-137, was defined as the study area. The addresses of women diagnosed with breast cancer were identified between 2001 and 2010. The data were geographically referenced and, using census data, the annual averages of crude incidence rates were estimated. The existence of clusters of new cases was ascertained by means of the Moran index. Correlations of radiometric measurements with the incidence were assessed using unconditional linear regression. RESULTS: A total of 4,105 new cases were identified, of which 2,233 were in the study area, and of these, 1,286 (57.59%) were georeferenced. The gross rates of total and referenced cases were 102.91 and 71.86/100,000 women, respectively. These were close to the average for Brazilian state capitals, which is 79.37/100,000 women. The cluster analysis showed slight correlations in three small sets of census tracts, but these were far from the sources of contamination. The scatter plot of points and the R2 value close to zero indicated that there was no association between the variables. CONCLUSION: This study reinforces the hypothesis that the ionizing radiation levels to which women living in Goiânia are now exposed to are not associated with the onset of new cases of breast cancer.

ABSTRACT

El angiosarcoma de la mama es un tumor maligno de origen endotelial vascular que puede ser primario, si surge sin un precursor conocido, o secundario, si ocurre en el sitio de la piel previamente irradiada. En este último caso, se conoce como angiosarcoma inducido por radiación (rias) del seno. Se trata de una complicación rara y tardía de la radioterapia del cáncer de mama, con una alta tasa de recurrencia y progresión. En este artículo, presentamos el caso de una paciente de sexo femenino de 73 años, con antecedentes de carcinoma infiltrante de mama derecha, tratada con cirugía conservadora y posterior radioterapia, quien, al quinto año de seguimiento, presentó múltiples nódulos de color violáceo en los 4 cuadrantes de la mama previamente irradiada. El diagnóstico fue de angiosarcoma radioinducido, realizándose mastectomía y reconstrucción inmediata con colgajo de dorsal ancho, en la que, de forma inicial, se obtiene una resección R1 (microscópicamente márgenes < 1 cm). En espera de ampliación de márgenes, la paciente comienza con síntomas respiratorios y se documenta progresión pulmonar. Conclusión: La sospecha e identificación de los angiosarcomas radioinducidos permite realizar un manejo oportuno y preciso de una patología poco frecuente y con un comportamiento muy agresivo


Angiosarcoma of the breast is a malignant tumor of vascular endothelial origin that can be primary, if it arises without a known precursor, or secondary, if it occurs at the site of previously irradiated skin. In the latter case, it is known as radiation-induced angiosarcoma (rias) of the breast. It is a rare and late complication of radiation therapy for breast cancer, with a high rate of recurrence and progression. In this article, we present the case of a 73-year-old female patient with a history of infiltrating carcinoma of the right breast, treated with conservative surgery and subsequent radiotherapy, who, at the fifth year of follow-up, presented multiple purplish-colored nodules in the 4 quadrants of the previously irradiated breast. The diagnosis was radio-induced angiosarcoma, performing a mastectomy and immediate reconstruction with a latissimus dorsi flap, in which, initially, an R1 resection was obtained (microscopically margins < 1 cm). While waiting for margin expansion, the patient begins with respiratory symptoms and pulmonary progression is documented. Conclusions: The suspicion and identification of radio-induced angiosarcomas allows timely and precise management of a rare pathology and with very aggressive behavior

ABSTRACT

Objetivo: Descrever os fatores envolvidos no processo de amamentação do bebê pré-termo internado em uma Unidade Neonatal registrados em um "Diário do bebê" preenchido pela mãe. Método: Pesquisa descritiva, prospectiva e longitudinal, com abordagem quantitativa, realizada no período de setembro de 2010 a junho de 2011 com 38 mães de recém-nascidos pré-termo internados na Unidade Neonatal. Resultados: Predomínio de mães com idade entre 20 a 34 anos, com companheiro, escolaridade maior de oito anos, renda familiar entre um a cinco salários mínimos, e não possuíam experiência prévia com aleitamento materno de outros filhos. A frequência do uso do diário foi maior ou igual a três vezes/semana; a média de número de ordenhas diárias foi maior ou igual a três e a duração da ordenha de 16 a 30 minutos. A média de volume ordenhado foi menor ou igual a 100 ml/semana. Conclusão: O sucesso da amamentação do bebê pré-termo na Unidade Neonatal depende de vários fatores associados e continua sendo um desafio para as mães, profissionais de saúde e família, porém estratégias como incentivo para o registro no diário mostraram-se adequadas para sua manutenção e para a intervenção de enfermagem na prática assistencial.(AU)


Objective: To describe the factors involved in the breastfeeding process of preterm infants hospitalized at a Neonatal Unit recorded in a "Baby diary" completed by the mother. Method: This is a descriptive, prospective and longitudinal study that uses a quantitative approach. The study was conducted between September 2010 and June 2011 with 38 mothers of preterm infants hospitalized at a Neonatal Unit. Results: There was prevalence of mothers aging between 20 and 34 years old and that have partners. These mothers had eight or more years of school education, family income betwen one and five mininum wages, and no previous experience in breastfeeding other children. The frequency of use of the diary was equal or greater than three times per week. The average daily breast pumpings was equal or greater than three and the duration of the breast pumping was between 16 and 30 minutes. The average expressed breast milk volume was equal or less than 100 mL per week. Conclusion: The success of breastfeeding of preterm infants at the Neonatal Unit depends on several associated factors and continues to be a challenge to mothers, healthcare professionals and families. However, strategies to promote registering on baby diraries seems to be adequate ir order to maintain breastfeeding and to guide interventions from nurses in the assistential practice.(AU)
