ABSTRACT
Este manuscrito presenta un caso de un leiomioma orbitario de larga evolución en un joven de 14años. El tumor era inusualmente grande y causaba una proptosis severa y una afectación importante de la musculatura ocular. El paciente presentaba amaurosis, una oftalmoplejía completa, dolor ocular espontáneo e incapacidad para cerrar los párpados. Debido al tamaño del tumor y a su progresión, se realizó una exenteración orbitaria derecha para eliminar todo el contenido orbitario, incluyendo el tumor y el globo ocular. El procedimiento quirúrgico tenía como objetivo prevenir la recurrencia del tumor y mejorar la calidad de vida del paciente. El análisis histopatológico confirmó el diagnóstico de leiomioma orbitario. Este caso presenta un interés particular por el grado de evolución que ha alcanzado. La extirpación completa del tumor y un seguimiento a largo plazo son necesarios para prevenir la recurrencia y garantizar resultados óptimos para el paciente. Además, este caso refleja las grandes diferencias en el acceso a la sanidad en las diferentes regiones del mundo. (AU)
This manuscript describes an exceptional case of a long-standing orbital leiomyoma in a 14-year-old male. The tumor was unusually large, causing severe proptosis and significant involvement of the ocular muscles. The patient presented with amaurosis, complete ophthalmoplegia, spontaneous eye pain, and the inability to close the eyelids, leading to psychological distress. Due to the tumor's size and progression, a right orbital exenteration was performed to remove all orbital contents, including the tumor and the eyeball. The surgical procedure aimed to prevent tumor recurrence and improve the patient's quality of life. The histopathological analysis confirmed the diagnosis of orbital leiomyoma. This case presents a particular interest due to the degree of evolution it has reached. Complete tumor excision and long-term follow-up are necessary to prevent recurrence and ensure optimal patient outcomes. This report underscores global healthcare disparities and the complexity of managing rare orbital neoplasms in diverse country settings. (AU)

Objective: To report the treatment and clinical monitoring in patients with prostatic evanescent carcinoma at Hospital Carlos Andrade Marin. Methods: We reviewed the medical records of 148 patients undergoing by robot-assisted radical prostatectomy in Carlos Andrade Marin hospital. The cases reported between January 2016 to December 2018. The diagnosis was carried by taking a transrectal prostate biopsy with 12 cylinders. This samples are studied by the pathologist who reviews the radical prostatectomy surgery. Results: Three patients had prostatic evanescent carcinoma, which those cases showed Gleason 6 (3+3) prostate cancer. Two received neoadjuvant hormone therapy and the other patient presented minor tumor invasion in 1 out of 12 cylinders used during the biopsy. In the three cases, after the sample analysis, there was no residual tumor evidence. Therefore, they were classified as pT10. Conclusions: In this study, the results obtained from the patients studied presents the incidence of prostatic evanescent carcinoma is 2%. The combination of these different factors such as clinical status, preoperative PSA, number of positive cylinders and the invasion percentage, additionally to the usage of neoadjuvant hormone therapy prior the radical prostatectomy can help to predict evanescent carcinoma of the prostate (AU)
Objetivos: Reportar la experiencia del Hospital Carlos Andrade Marín en el tratamiento y seguimiento de pacientes con cáncer de próstata evanescente.Materiales y Métodos: Se ha estudiado las historiasclínicas de 148 pacientes que se realizaron prostatectomíaradical asistida por robot en el Hospital Carlos AndradeMarín en el periodo enero 2016 hasta diciembre 2018, eldiagnostico se realiza mediante toma de biopsia prostáticatransrectal con toma de 12 cilindros, los cuales son estudiados por el mismo medico patólogo que revisa la piezaquirúrgica de prostatectomía radical.Resultados: Se identifican tres casos de carcinomade próstata evanescente, los cuales presentan carcinoma depróstata Gleason 6 (3+3), dos reciben terapia neoadyuvantehormonal y uno presenta escasa invasión tumoral en 1/12cilindros de biopsia prostática (cáncer de próstata diminuto). En los tres casos después del análisis de las piezasquirúrgicas no se evidencia tumor residual por lo que se loscataloga como pT0.Conclusiones: En nuestra experiencia la incidenciade carcinoma de próstata evanescente es del 2% en elgrupo de pacientes estudiados. La combinación del estadio clínico, PSA preoperatorio, numero de cilindros positivos y el porcentaje de invasión de los mismos como el usode neoadyuvancia previo a la prostatectomía radical puedeayudar a predecir el fenómeno de carcinoma de próstata evanescente (AU)

ABSTRACT: The use of resin sealants has shown partial infiltration of White-Spot Enamel Lesions in vitro (WSEL). The aim of the present study was to perform a morphological evaluation of natural WSEL when infiltrated using a commercially available sealant (Concise, 3M- ESPE). 20 bicuspids extracted for orthodontic reasons from patients ranging 18 to 30 years old, which had WSEL, were used in this study. The patients agreed to donate their teeth by signing a written consent. Every WSEL was assessed microscopically (Stereo Zeiss Axiscop) and then photographed (ProScope HR microscope). Prior to applying the sealant the lesion was etched using phosphoric acid at 37 % (3M-ESPE, St Paul, MN, USA.) for 30 seconds, washed for 40 seconds and then air-dried. The sealant was marked with rhodamine B (1mg/ml) and was applied according to the manufacturer directions. A specimen of approximately 100 mm was obtained for every WSEL by cutting perpendicularly through the lesion (Isomet 1000, Buehler Co.) and grinding (600 grit). The specimens were evaluated using: clear camp, polarized light, and epifluorescence microscopy. Images were taken of each specimen for every microscopic evaluation using a slide film (Kodak Ektachrome film 400 ASA). The images were digitalized by scanning at 1200 dpi resolution (Epson Filmscan 200) and then saved as JPEG and TIFF files. The sealant infiltration into The WSEL was assessed by means of analysis, processing and digital superimposing using Adobe Photoshop 7.0 and Matrox Inspector 1.07. It was concluded that the sealant infiltrated the whole body zone of the lesion. The depth of penetration of sealants into White Spot Enamel Lesion plays an important role in the control of caries lesion progression.
RESUMEN: El uso de sellantes de resina ha demostrado lograr la infiltración parcial de lesiones de mancha blanca en esmalte in vitro (LMBE). El objetivo del presente estudio fue realizar una evaluación morfológica de la infiltración a LMBE naturales utilizando un sellante disponible comercialmente (Concise, 3M-ESPE). Se utilizaron en este estudio, 30 bicúspides extraídos por razones de ortodoncia en pacientes que tenían entre 18 a 30 años de edad, y presentaban LMBE. Los pacientes aceptaron donar sus dientes firmando un consentimiento informado. Cada LMBE se evaluó microscópicamente (Stereo Zeiss Axiscop) y luego se fotografió (microscopio ProScope HR). Antes de aplicar el sellante, la lesión se grabó usando ácido fosfórico al 37 % (3M-ESPE, St Paul, MN, EE. UU.) durante 20 segundos, luego se lavó durante 40 segundos y finalmente se secó con aire de jeringa triple. El sellante se marcó con rodamina B (1 mg / ml) y se aplicó siguiendo las instrucciones del fabricante. Se obtuvo una muestra de aproximadamente 100 mm para cada LMBE cortando perpendicularmente a través de la lesión (Isomet 1000, Buehler Co.) y trituración (grano 600). Las muestras se evaluaron usando: campo claro, luz polarizada y microscopía de epifluorescencia. Se tomaron imágenes de cada espécimen para la evaluación microscópica usando una película deslizante (Kodak Ektachrome film 400 ASA). Las imágenes se digitalizaron escaneando a una resolución de 1200 ppp (Epson Filmscan 200) y luego se guardaron como archivos JPEG y TIFF. La infiltración del sellante en las LMBE se evaluaron mediante análisis, procesamiento y superposición digital utilizando Adobe Photoshop 7.0 y Matrox Inspector 1.07. Se concluyó que el sellante infiltró toda la zona del cuerpo de la lesión. La capacidad de penetración en profundidad de los sellantes en Lesiones de Mancha Blanca del Esmalte desempeñan un rol importante en el control de la progresión de las lesiones de caries.
