El proceso de formación del especialista en Anatomía Patológica en Cuba, juega un rol significativo en contribuir con la prevención, diagnóstico y tratamiento de los principales problemas de morbimortalidad con el interés de elevar los estándares de vida. El presente artículo está dirigido a caracterizar el proceso de formación de la habilidad diagnóstica en los residentes de la especialidad Anatomía Patológica. Se realizó una investigación en la que se utilizó un total de 27 residentes de la Especialidad de anatomía patológica de la Universidad de Ciencias Médicas de Pinar del Río en los meses de octubre a diciembre del 2021. Se emplearon métodos teóricos: análisis-síntesis, modelación y sistémico-estructural y empíricos: análisis de documentos, observación, encuesta y entrevista. Los resultados obtenidos revelan que el 100 % de los residentes encuestados, no tenían dominio de los aspectos fundamentales del plan de estudio de la especialidad, 80 % mostraron escasa definición de la habilidad diagnóstica a formar durante la especialidad y el restante 20 % no la tiene definida. Todos los docentes desconocen las habilidades más generales del módulo que imparten, 98 % desconocen la relación entre habilidades y demás componentes del proceso, 70,2 evalúan de regular el proceso de formación de la habilidad diagnóstica en los residentes. En el estudio se concluye que la formación de la habilidad diagnóstica en la especialidad de Anatomía Patológica se realiza de manera espontánea y no secuenciada; no posibilita que el residente sistematice las acciones necesarias para su dominio y no se encuentra debidamente estructurado.

Introduction: bladder cancer is a more common tumor that sometimes the statistics database or media conveyed to us. It ranks ninth concerning cancer diagnoses worldwide and it is reported to be approximately five times more frequent in males than in females. Objective: to describe the clinicopathologic features of malignant lower urinary tract tumors. Method: a descriptive and cross-sectional study involving a total of 186 patients was conducted. Anatomical and pathological diagnoses were carried out to all patients with malignant lower urinary tract tumor at the Hospital Provincial Clínico Quirúrgico Docente “Saturnino Lora Torres” in Santiago de Cuba, from 2017 throughout 2020. Once the data were collected, they were processed using the SPSS statistical system, version 21.0. Results: most affected patients with lower urinary tract tumor had an average age of 60 to 70, arising most frequently in males. The 96.4 % of the total of the patients were diagnosed with urothelial carcinomas (predominant), described in its papillary variety and the high degree of malignant transformation. Conclusions: malignant lower urinary tract tumors are health problems labeled as the low frequency which differ in their transformation according to the patient. The clinical pathological behavior of the tumor, in a general sense, was similar to that reported in the national and international literature, except for small and pointed differences regarding symptoms, histological diagnosis, and the degree of the lesions´ malignant transformation.

Introduction: In a pathological anatomy service, the workload in medical time is analyzed based on the complexity of the samples received and its distribution among pathologists is assessed, presenting a new computer algorithm that favors an equitable distribution., Methods: Following the second edition of the Spanish guidelines for the estimation of workload in cytopathology and histopathology (medical time) according to the Spanish Pathology Society-International Academy of Pathology (SEAP-IAP) catalog of samples and procedures, we determined the workload units (UCL) per pathologist and the overall UCL of the service, the average workload of the service (MU factor), the time dedicated by each pathologist to healthcare activity and the optimal number of pathologists according to the workload of the service., Results: We determined 12 197 total annual UCL for the chief pathologist, as well as 14 702 and 13 842 UCL for associate pathologists, with an overall of 40 742 UCL for the whole service. The calculated MU factor is 4.97. The chief pathologist devoted 72.25% of his working day to healthcare activity while associate pathologists dedicated 87.09% and 82.01% of their working hours. The optimal number of pathologists for the service is found to be 3.55., Conclusions: The results demonstrate medical work overload and a non-equitable distribution of UCLs among pathologists. We propose a computer algorithm capable of distributing the workload in an equitable manner. It would be associated with the laboratory information system and take into account the type of specimen, its complexity and the dedication of each pathologist to healthcare activity., (Copyright © 2024 Sociedad Española de Anatomía Patológica.

Introduction and Objective: Artificial intelligence is fully present in our lives. In education, the possibilities of its use are endless, both for students and teachers., Material and Methods: The capacity of ChatGPT has been explored when solving multiple choice questions based on the exam of the subject «Anatomopathological Diagnostic and Therapeutic Procedures» of the first call of the 2022-23 academic year. In addition, to comparing their results with those of the rest of the students presented the probable causes of incorrect answers have been evaluated. Finally, its ability to formulate new test questions based on specific instructions has been evaluated., Results: ChatGPT correctly answered 47 out of 68 questions, achieving a grade higher than the course average and median. Most failed questions present negative statements, using the words «no», «false» or «incorrect» in their statement. After interacting with it, the program can realize its mistake and change its initial response to the correct answer. Finally, ChatGPT can develop new questions based on a theoretical assumption or a specific clinical simulation., Conclusions: As teachers we are obliged to explore the uses of artificial intelligence and try to use it to our benefit. Carrying out tasks that involve significant consumption, such as preparing multiple-choice questions for content evaluation, is a good example., (Copyright © 2024 Sociedad Española de Anatomía Patológica.

In January 2020, the new betacoronavirus SARS-CoV-2 was identified and classified in the pathogens group as HG3, It has not totally been clarified its pathogenic potential nor its transmission dynamic. In Mexico, the epidemiologic surveillance sentinel model estimates that there are more undiagnosed cases of COVID-19, this scenario demands to enforce the risk mitigation measures in order to prevent contagious among staff in pathology laboratories in particular. Our objective is to acknowledge the organization criteria, functions as well as the minimum material and technological resources necessary, for the proper manage and transport of corpses, conducting postmortem studies, handling surgical specimens, frozen section studies and cytological studies in the Pathology laboratory in cases with suspicion or with COVID-19 and other similar airborne pathogens. COVID-19 has exhibited worldwide, the shortcomings of current practice of medicine, not excluding what happens in Pathological Anatomy where there is laggard and sometimes contempt for postmortem study, COVID-19 pandemic has clearly demonstrated that only those places where it has been invested in equipment and qualified personnel in autopsy room, will be the first to fully understand the physiopathogenesis of SARS-CoV-2 and will be able to develop ideal protocols to COVID-19 management. Thus, we must ask ourselves if we will be able to learn this hard lesson. [ABSTRACT FROM AUTHOR]

RESUMEN Antecedentes: En anatomía patológica, existen variedad de agentes químicos que deben ser controlados. Por su potencial cancerígeno destacan el Formaldehído (CH2O), Xileno y los Compuestos Orgánicos Volátiles (COVs). Objetivo: Valorar la eficacia del uso de purificadores mediante la fotocatalización y los sistemas de friocongelación, para el control de los niveles de exposición a CH2O, Xileno y COVs. Objetivo Secundario: Comparar mediciones de Formaldehído con otros 3 hospitales de la Comunidad de Madrid. Metodología: Se realizaron 26 mediciones ambientales en Anatomía Patológica del Hospital Universitario de Fuenlabrada (HUF), en febrero del año 2017 y en marzo del mismo año, posterior a la instalación de los purificadores y sistemas de friocongelación, en las áreas de laboratorio y sala de tallado. Se valora Xileno y COVs con el método PID (detector de fotoionización, PID por sus siglas en inglés, PhotoIonization Detector) y de CH2O a través de un Sistema de Detección de Gas. Como criterio para valorar la exposición a COVs se tomó como gas de referencia el isobutileno con un VLA-EC de 100 ppm. Para el Xileno se compararon los resultados con el VLA-EC 100 ppm y para el CH2O con el VLA-EC de 0,3 ppm, establecidos en la guía de «Límites de Exposición Profesional para Agentes Químicos» del Instituto Nacional de Seguridad e Higiene en el Trabajo. Resultados: Los niveles de exposición previos no superaban los valores límites. Se observó que tras la implantación de las medidas preventivas colectivas estos valores disminuyeron, obteniéndose resultados estadísticamente significativos: COVs (p= 0.0002; IC 95% 2.393- 5.506), Xileno (p= 0.0002; IC 95% 1.021- 2.359) y CH2O (p= 0.0004; IC 95% 0.210-0.350). Conclusiones: El sistema integral de friocongelación y purificación mediante fotocatalización optimizan el control de la exposición a dichos agentes químicos, anulando las fuentes de emisión.

Aim: meningiomas account for 15-20% Central Nervous System primary neoplasms in adults. Many are benign, but the 5% of them are malignant. MRI characterizes them, describing a series of radiological findings suggestive of aggressiveness, although the diagnosis is confirmed by histopathology. Objectives: Determine if the aggressiveness of intracranial meningiomas using MRI is consistent with histopathology. Material and Methodology: 14 cases of meningiomas with MR imaging and histopathology ranging 2004 to 2016 were reported. Its radiological characteristics were analyzed by determining their aggressiveness by MRI and Histopathology, carried out a study of diagnostic tests. Results: 7 (50%) of the 14 meningiomas were aggressive in the study by MRI, while 4 (28.6%) did so by histopathology. The sensibility of MRI was 100% and specificity 70%. The only variables that achieved p<0.05 by studying aggression MRI were irregular borders and heterogeneous enhancement. Conclusions: MRI is suitable for use as initial screening in the diagnosis of intracranial meningiomas aggressiveness, being restricted for confirmatory diagnosis. We found no significant evidence to determine what radiological characteristics define tumor aggressiveness. [ABSTRACT FROM AUTHOR]

Se efectuó un estudio descriptivo de 35 pacientes con leucoplasia bucal homogénea asociada al tabaquismo, atendidos en la consulta de Cirugía Maxilofacial del Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" de Santiago de Cuba, desde enero de 2007 hasta igual mes de 2009, con vistas a determinar las características histomorfométricas de las biopsias correspondientes, lo cual podría contribuir a precisar su diagnóstico. Se realizó el examen histomorfométrico del grosor epitelial, así como también de los diámetros nuclear y citoplasmático; también se midió la densidad del infiltrado linfocitario y vascular en la lámina propia y de la hipercromatosis. Los valores más pequeños del diámetro nuclear fueron los más frecuentemente encontrados, con una fuerte asociación con el citoplasmático. Estos parámetros resultaron ser los de mayor significado para el diagnóstico de la mencionada afección.

Se realizó un estudio descriptivo y transversal de 58 fumadoras con edades de 59 a 80 años y diagnostico histopatológico por biopsia o necropsia de una enfermedad maligna, cuyas muestras fueron procesadas en el departamento de Anatomía Patológica del Hospital Clinicoquirúrgico Docente "Dr. Ambrosio Grillo Portuondo" de Santiago de Cuba, desde 2008 hasta 2010, a fin de determinar la relación existente entre los cánceres de mama y pulmón con el hábito de fumar en féminas posmenopáusicas. Se analizaron variables, tales como: antecedentes patológicos personales, presencia del hábito tabáquico, edad de comienzo del hábito, localización del tumor (tanto en biopsias como en necropsias), tipo histológico del cáncer y otros hallazgos anatomopatológicos. En la serie predominaron el grupo etario de 59-70 años (53,4 %), los cánceres de mama y pulmón (39,6 y 48,5 %, respectivamente), el carcinoma como la variante histológica más observada y la aterosclerosis como el hallazgo anatomopatológico más frecuente.A descriptive and cross-sectional study was carried out in 58 smokers aged 59-80 years and histopathological diagnosis of malignant disease by biopsy or autopsy, whose samples were processed at the Pathology Department of "Dr Ambrosio Grillo Portuondo" Provincial Clinical and Surgical Teaching Hospital in Santiago de Cuba, from 2008 to 2010, to determine the relation of breast and lung cancers to the smoking habit in postmenopausal women. Variates such as past medical history, smoking habit, age at onset of smoking, tumor location (both in biopsies and autopsies), histological type of cancer and other pathologic findings were analyzed. Age group of 59-70 years (53.4%), breast and lung cancers (39.6% and 48.5%, respectively), carcinoma as the most observed histological type and atherosclerosis as the most frequent pathologic finding predominated in the series.

La punción aspirativa con aguja fina es un método de diagnóstico rápido, eficaz, sencillo de ejecutar, de bajo costo y apenas causante de complicaciones leves, por lo que ha devenido el estudio fundamental, pues además de permitir iniciar la secuencia diagnóstica de los tumores, garantiza que el patólogo o citopatólogo apoye y brinde información de valor al médico clínico para el adecuado tratamiento de pacientes con procesos tumorales. La morbilidad atribuible al procedimiento se considera insignificante y en series escandinava y estadounidense, en las cuales se estudió mediante cortes de tejidos la zona de la vía de entrada previamente marcada, no se halló siembra celular alguna en el trayecto de la aguja.Aspiration punction with fine needle is an easily obtained, low cost, quick, effective diagnosis method which hardly causes mild complications, so it has become the fundamental study, because besides allowing to begin the diagnostic sequence of tumors, it guarantees that the pathologist or cytopathologist supports and offers valuable information to the clinical doctor for the appropriate treatment of patients with tumoral disorders. The morbidity attributable to the procedure is considered insignificant and in Scandinavian and American series, in which the area of the previously marked entrance was studied by means of tissue cuts, cell seeding was not found in the needle route.

Se efectuó un estudio descriptivo, transversal, retrospectivo y analítico de 35 pacientes con leucoplasia bucal homogénea asociada al hábito de fumar, atendidos en la consulta de Cirugía Maxilofacial del Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" de Santiago de Cuba desde enero de 2007 hasta igual mes de 2009, con vistas a determinar la presencia de alteraciones de la queratinización como paraqueratosis, ortoqueratosis y disqueratosis, pero también de displasia epitelial. La información primaria se obtuvo a través del estudio histopatológico de las biopsias realizadas y procesadas en el Departamento de Anatomía Patológica de la mencionada institución. La característica microscópica distintiva fue la hiperparaqueratosis, existiese desarrollo anormal de tejido o no.A descriptive, retrospective, cross-sectional, and analytical study of 35 patients with homogeneous oral leucoplakia associated to the smoking habit, assisted at the Outpatient Department of Maxillofacial Surgery from "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital in Santiago de Cuba was carried out from January, 2007 to the same month of 2009, aimed at determining the presence not only of changes of keratinisation as parakeratosis, orthokeratosis, and dyskeratosis, but also of epithelial dysplasia. The primary information was obtained through the histological-pathological study of the biopsies processed in the Pathology Department of the aforementioned institution. The distinctive microscopic characteristic was the hyperparakeratosis, with the presence of the abnormal development of the tissue or without it.

La enfermedad de la próstata es hoy un problema de salud por su elevada morbilidad y mortalidad en adultos mayores de 50 años. Acerca de ello se realizó este estudio descriptivo y transversal sobre los hallazgos histopatológicos de neoplasia intraepitelial prostática en las biopsias de próstata útiles, recibidas para su análisis en el Departamento de Anatomía Patológica del Hospital Clinicoquirúrgico Docente "Dr. Ambrosio Grillo Portuondo" de Santiago de Cuba durante el bienio 2008-2009. Entre los principales resultados sobresalió la confirmación, por la mencionada vía, de hiperplasia fibroadenomatosa de la próstata, lesiones prostáticas, carcinomas y otras alteraciones en esa glándula masculina. Los datos obtenidos ratificaron que el diagnóstico a través de muestras de tejido de neoplasia intraepitelial prostática, constituye una de las formas en que los patólogos pueden contribuir a la oportuna detección del carcinoma prostático.The prostate disease is a health problem nowadays due to its high morbidity and mortality in adults older than 50 years. Based on this, a descriptive and cross sectional study was carried out on the histopathologic findings of the prostatic intraepithelial neoplasia in the useful prostate biopsies examined in the Pathology Department of "Dr. Ambrosio Grillo Portuondo" Clinical Surgical Teaching Hospital in Santiago de Cuba during the biennium 2008-2009. Among the main results there were: the confirmation of prostate fibroadenomatous hyperplasia, prostatic lesions, carcinomas and other alterations in that male gland, all through biopsy. The obtained data confirmed that the diagnosis through samples from the prostatic intraepithelial neoplasia tissue, constitutes one of the ways by which pathologists can contribute to the opportune detection of the prostatic carcinoma.

Se identificaron y describieron algunos aspectos importantes para mantener la conducta ética en el Departamento de Anatomía Patológica, con vista a obtener un mejor desarrollo de la práctica profesional y lograr la excelencia en la atención de salud. Se concluyó que deben ser incluidos elementos como la formación integral de sus trabajadores, con prioridad en los requerimientos éticos y vocacionales; la colaboración de los profesionales del citado departamento con los médicos de asistencia en los procesos de diagnóstico y la información al paciente, así como el establecimiento de una adecuada filosofía de trabajo.Some significant issues to maintain the ethical behaviour in the Pathology Department, in order to obtain a better development of the professional practice and to achieve excellence in health assistance were identified and described. It was concluded that elements as integral training of workers should be included, with priority in the ethical and vocational requirements; the collaboration of the professionals of this department with the assistance of the clinicians on the processes of the diagnosis and the information to the patient, as well as the establishment of a suitable work philosophy.

La tuberculosis, infección bacteriana crónica causada por el Mycobacterium tuberculosis, declarada por la OMS (1993) como emergencia epidemiológica, afecta mayoritariamente los pulmones, pero puede afectar a otros órganos (Tb. Extrapulmonar), entre estos a la laringe, constituyendo la más frecuente enfermedad granulomatosa a este nivel y considerada una localización rara (menos de 1%); por ello nuestro interés de presentar un caso de Tuberculosis en faringe y laringe, con el objetivo de resaltar lo infrecuente de esta ubicación, los problemas diagnósticos y la importancia del estudio histopatológico. Paciente de 49 años, femenina, consulta por Odinofagia, se encuentra tumor en faringe, se realiza biopsia y el diagnóstico fue: Sarcoidosis faríngea, no regresó a consulta. Meses después asiste por disfonía, se visualiza tumor en laringe, se realiza biopsia y el informe fue carcinoma de laringe; se negó a tratarse. Cuatro meses más tarde, ingresa en el Hospital Neumológico, por disnea, tos y disfonía, el diagnóstico fue tuberculosis pulmonar (Cod 9). Interconsultan con Otorrinolaringología el tratamiento del cáncer laríngeo. Decidimos nueva revisión de las biopsias, y se arribó a las conclusiones siguientes: "Tuberculosis miliar acorde con su cuadro clínico y hallazgos anatomo-patológicos: (faringitis y laringitis granulomatosa); no se corresponde ni con Sarcoidosis ni con carcinoma Epidermoide previamente reportado."Tuberculosis is a chronic bacterial disease caused by Mycobacterium tuberculosis, declared by WHO in 1993 as epidemilogical emergency warning, affecting mostly the lungs but it can also damage others organs (Extra lung Tb) such as the larynxbeing the most frequent granulomatous disease as this level and it considered as a rare location (less than 1%), that is why we are so interested in presenting this case report of larynx and pharynx disease, with the aspiration to highlight how few are the cases with this location, the diagnostic problems and the importance of a histopathologic analysis. 49 years, female patient came to the consultation because of odenaphagia. A pharyngeal tumour was diagnosed and a biopsy was undergone which revealed pharyngeal Sarcoidosis. The patient did not come back to the consultation until several months later due to diphonia. A tumour in the larynx is visualized and a biopsy is undergone again which shoved to the positive for laryngeal cancer; the patient refuses to be treated. Four months later the patient is admitted to the hospital in the Neumology hospital with a clinical picture of dyspnea, cough and dysphonic. The diagnosis was pulmonary tuberculosis. A consult is carried out which the otorrhynolaringologyst and a new consideration came out, concluding by pathological anatomy as tuberculosis. Taking into account the clinical picture and the anatomopathological firdings that do not corresponded inther with Sarcoidosis or Epidermoide carcinoma previously reported. The characteristics of this case led to this presentation.

Hemos revisado de forma retrospectiva 18 casos de tumor filodes, diagnosticados histopatológi-camente durante un período de 6 años, recogiendo los datos clínicos, radiológicos y evolutivos. Todos los casos se presentaron como nodulo palpable, fibroelástico e indoloro excepto uno que lo hizo como mastitis sobre tumoración. En mamografía mostraron densidad homogénea, bordes relativamente bien definidos, sin calcificaciones en su interior. Ultraso-nográficamente aparecieron como masas sólidas, heterogéneas, con refuerzo posterior y algunas de ellas con áreas quísticas características. En todos los casos se realizó tratamiento quirúrgico y en 15 pacientes se hizo punción aspirativa con aguja fina (PAAF), previo a la cirugía. Los datos evolutivos en relación a recidiva local y metástasis son similares a los descritos en la bibliografía. Recomendamos estrecha vigilancia clínico-radiológica debido a la historia natural del tumor y su alto número de recidivasWe have revised in retrospective study, 18 cases of phyllodes breast tumor diagnosed histolo-gically over a 6 year-period, gathering the clinical, radiological and evolutionary data. All the cases appeared as palpable, elastic and painless nodules. Mammography showed homogeneous density, relatively well defined borders, without internal calcifications. Ultrasonographically they appeared as solid masses, heterogeneous, with posterior enhancement and, some of them with characteristic cystic areas. Fine needle aspiration biopsy was made in 15 patients, before the surgical treatment that was carried out in all the cases. The information related to local relapse and metastasis is similar to those described in the bibliography. We recommend close clinical-radiological surveillance, due to the natural history of the tumour and their high number of relapses
