Tamizaje con citología anal en mujeres con lesiones premalignas del cuello uterino / Anal cytology screening in women with premalignant lesions of the uterine cervix / Rastreamento de citologia anal em mulheres com lesões pré-malignas do colo do útero

Objetivo: nuestro objetivo principal fue evaluar la prevalencia de citología anal patológica en mujeres con antecedentes de neoplasia intraepitelial cervical. Métodos: se trata de un estudio de cohorte transversal desde mayo de 2018 a agosto de 2020 en el Centro Hospitalario Pereira Rossell. Se estudiaron dos cohortes: una de mujeres que tenían diagnóstico de neoplasia intraepitelial cervical y otra de control de mujeres sanas que asistieron al control, con una proporción de 2:1. Se calculó un tamaño muestral total de 205 pacientes, siendo 135 pacientes con NIC con un IC del 95%, suponiendo una prevalencia del 10% de lesiones preneoplásicas anales. El tamaño muestral de la cohorte control fue de 70 pacientes según la relación preestablecida. Resultados: se encontró asociación entre la presencia de lesiones premalignas cervicales y anomalías epiteliales detectadas en la citología anal, con un cociente de prevalencia de 1,77 (IC del 95%: 1,19-2,62) y un odds ratio de 2,69 (1,36-5,30). No se encontraron diferencias significativas en las variables de raza, tipo de relación sexual o tabaquismo. Conclusiones: nuestro estudio concluye que existe una asociación entre la neoplasia intraepitelial cervical relacionada con el VPH y la citología anal patológica.

Objective: the main objective of the study was to assess the prevalence of anal cytology in women with a history of cervical intraepithelial neoplasia. Method: cohort transversal study conducted from May, 2018 until August, 2020 at Pereira Rossell Hospital. Two cohorts were studied, one of which included women with a diagnosis of cervical intraepithelial neoplasia and the other one included healthy women who attended their routine follow up, in a 2:1 ratio. The total size of the sample was 205 patients, 135 of which were patients with cervical intraepithelial neoplasia (confidence interval being 95%), presuming a 10% prevalence of anal pre-neoplasic lesions. The sample size of the control cohort was 70 patients as per the pre-defined ratio. Results: a association was found between the presence of malignant lesions of the cervix and epithelial anomalies detected in the anal cytology, with a prevalence coefficient of 1.77 (CI: 95%: 1,19 - 2,62) and odds ratio of 2,69 (1,36 - 5,30). No significant differences were found between race, type of sexual relationships or smoking variables. Conclusions: our study concludes there is an association between cervical intraepithelial neoplasia related to HPV and pathological anal screening.

Métodos: Trata-se de um estudo de coorte transversal de maio de 2018 a agosto de 2020, no Hospital Pereira Rossell. Foram estudadas duas coortes, uma de mulheres com diagnóstico de neoplasia intraepitelial cervical e outra de controle de mulheres saudáveis que compareceram ao controle na proporção de 2:1. Foi calculada uma amostra total de 205 pacientes, 135 pacientes com NIC com um IC de 95%, assumindo uma prevalência de 10% de lesões pré-neoplásicas anais. O tamanho da amostra da coorte controle foi de 70 pacientes de acordo com a relação pré-estabelecida. Resultados: Foi encontrada associação entre a presença de lesões pré-malignas cervicais e anormalidades epiteliais detectadas na citologia anal, com razão de prevalência de 1,77 (IC 95%: 1,19 - 2,62) e odds ratio 2,69 (1,36-5,30). Não foram encontradas diferenças significativas nas variáveis raça, tipo de relação sexual ou tabagismo. Conclusões: Nossos resultados mostram uma associação entre neoplasia intraepitelial cervical relacionada ao HPV e citologia anal patológica.

Sarcoma uterino de topografía cervical / Sarcoma of the uterus of cervical topography / Sarcoma de colo de utero

Introducción: Los sarcomas uterinos son tumores poco frecuentes. Se originan en el tejido uterino de origen mesodérmico (músculo, tejido conjuntivo o estroma), siendo los más frecuentes los leiomiosarcomas, seguidos de los sarcomas del estroma endometrial. La expresión clínica de la enfermedad puede ser con sangrados genital, distensión abdominal y/o síntomas compresivos. Muchas veces se diagnostican en pacientes que son hatadas quirúrgicamente con diagnóstico de miomatosis uterina y, lo más frecuente es el diagnostico anatomopatológico posto peratorio de la pieza quirúrgica. El rol de la cirugía (histerectomía y anexectomía) es fundamental en el tratamiento. Descripción: El video presenta la evaluación diagnóstica y el abordaje quirúrgico de una paciente en la que se diagnosticó un leiomiosarcoma uterino de topografía cervical. Conclusiones: Se trata de una patología poco frecuente, con la particularidad de la ubicación, generando dificultades diagnósticas (clínica y paraclínicas) así como de abordaje quirúrgico.

Summary: Introduction: Sarcoma of uterus are rather unusual tumors. They ori ginate in the mesodermal tissue of the uterus (muscle, connective tissue or stroma), the most frequent ones being leiomyosarcoma, followed by endometrial stromal sarcomas. The clinical presentation of the disease may include genital bleeding, abdominal distention or compressive symptoms. They are often diagnosed in patients who are surgically treated with a diagnosis of uterine myoma, upon the postoperative pathological study of the surgical piece. The role of surgical treatment (hysterectomy and anexectomy) is of the essence. Description: The video presents the diagnostic assessment and sur gical approach of a patient who was diagnosed with leiomyosarcoma of the uterus with cervical topography. Conclusions: It it rather an unusual condition with a special loca tion. which results in diagnostic difficulties (both clini cal and paraclinical) as well as hi the surgical approach.

A expressão clínica da doença pode ser com sangramento genital, distensão abdominal e/ou sintomas compressivos. São frequentemente diagnosticados em pacientes tratadas cirurgicamente com diagnóstico de miomatose uterina e, mais frequentemente, com diagnóstico da anatomia patológica pós-operatória da peça cirúrgica. O papel da cirurgia (histerectomia e anexectomia) é essencial no tratamento. Descrição: O vídeo apresenta a avaliação diagnóstica e abordagem cirúrgica de uma paciente diagnosticada com leiomiossarcoma de colo de útero. Conclusões: É uma patologia pouco frequente, pela particularidade da sua localização, gerando dificuldades de diagnóstico (clínico e complementar) bem como de abordagem cirúrgica.

Comparison between vaginal and sublingual misoprostol 50 µg for cervical ripening prior to induction of labor: randomized clinical trial.

OBJECTIVE: To compare the effectiveness and safety of sublingual versus vaginal misoprostol on improving the Bishop score after 6 h of administration. METHODS: Randomized clinical trial which includes pregnant women in gestational ages from 32/0 to 41/6, with indication of induction of labor with misoprostol. Bishop score was assessed at the time of induction and 6 h after administration of 50 µg misoprostol. Analysis was made over difference in mean Bishop score of 2 points, using a standard deviation of 2, with 90% power, reaching a 95% confidence interval. RESULTS: 102 patients were studied, 51 received sublingual misoprostol, and 51 received vaginal misoprostol. There was a statistically significant difference in cervical modifications in global terms regardless of the administration route at 6 h (P < 0.05). When analyzing each group, there was no significant difference for the mean and standard deviation for Bishop score for sublingual and vaginal route (P = 0.761). There was no significant difference in terms of mode of delivery, Apgar score, cord pH, nor in the presence of complications. CONCLUSION: There is no statistically significant difference in terms of administration route for cervical ripening using misoprostol 50 µg, whether it was sublingual or vaginal.
