State of the art of cervical cancer treatment in rare histologies.

The objective of this review is to summarize the current scientific evidence to formulate clinical recommendations regarding the classification, diagnostic approach, and treatment of rare histological subtypes of cervical cancer; neuroendocrine carcinoma, gastric-type mucinous adenocarcinoma, and glassy cell adenocarcinoma. These histological subtypes are generally characterized by their low frequency, aggressive biological behavior, certain chemoradioresistance, and consequently, high recurrence rates with a deleterious impact on survival. Molecular studies have identified several associated mutations in neuroendocrine carcinoma (PIK3CA, MYC, TP53, PTEN, ARID1A, KRAS, BRCA2) and gastric-type adenocarcinoma (KRAS, ARID1A, PTEN) that may serve as molecular targets. While adenocarcinomas are typically treated and classified based on squamous histology across early, locally advanced, and advanced stages, the treatment strategies for neuroendocrine carcinomas in early stages or locally advanced cases differ, particularly in the sequencing of administering chemotherapy, chemoradiotherapy, or surgery. The chemotherapy regimen is based on etoposide plus cisplatin (EP). Unlike squamous cell carcinomas, immune checkpoint inhibitors are yet to establish a standard role in the treatment of recurrent neuroendocrine carcinomas due to the absence of clinical trials. Regarding glassy cell adenocarcinomas and gastric-type adenocarcinoma, the potential use of immunotherapy in advanced stages/disease requires further evaluation through international collaborations, given the limited number of cases.

Exploring Morphometric Features of the Female Reproductive Tract in Brazilian Pantanal Cattle / Un Análisis de las Características Morfométricas del Tracto Reproductivo Femenino en el Ganado del Pantanal Brasileño

SUMMARY: The cattle in the Pantanal region show a notable influence from Bos indicus breeds and their crossbreeds. However, a comprehensive biometric assessment of the reproductive system in these animals is currently lacking. This study evaluated the effects of breed, age, carcass weight, and estrous cycle phase on female reproductive system morphometry. A total of 124 healthy, non-pregnant reproductive tracts (83 Nelore and 41 Crossbred) were collected at a slaughterhouse. Neither the volume and weight of the ovaries nor the majority of uterine dimensions were affected by breed. Compared to heifers, cows showed longer uterine horns, a larger external caudal diameter of the uterine horns and body, and a greater external cranial diameter and internal caudal diameter of the cervix. The carcass weight (below vs. within commercial weight) affected the length of the uterine horns, uterine body, and cervix. Ovaries with a corpus luteum presented higher volume and weight than those with only follicles. Although the uterine measurements in the luteal phase were increased, the cycle stage did not affect the uterine morphometry. The average number of cervical rings was 5.0, independent of weight or breed. Crossbred animals presented a higher first cervical ring. Age didn´t influence the number, height, or distance between cervical rings. Deviation from the normal alignment of the cervix was recorded in 14.29 % of the animals, with a higher occurrence among Nelore cattle; deviation from the median axis was the most common (30%). This study emphasizes various parameters influencing the morphometry of the female reproductive system in Nelore cattle and their crosses, which could be crucial for implementing reproductive biotechnology techniques better suited to the morphological characteristics of zebu breeds.

El ganado de la región del Pantanal muestra una notable influencia de las razas Bos indicus y sus cruces. Sin embargo, actualmente falta una evaluación biométrica exhaustiva del sistema reproductivo de estos animales. Este estudio evaluó los efectos de la raza, la edad, el peso de la canal y la fase del ciclo estral sobre la morfometría del sistema reproductivo de la hembra. En un matadero se recogieron un total de 124 tractos reproductivos sanos y no preñados (83 Nelore y 41 cruzados). Ni el volumen ni el peso de los ovarios ni la mayoría de las dimensiones del útero se vieron afectados por la raza. En comparación con las novillas, las vacas mostraron cuernos uterinos más largos, un diámetro caudal externo más grande de los cuernos y del cuerpo uterino, y un diámetro craneal externo y un diámetro caudal interno más grandes del cuello uterino. El peso de la canal (por debajo versus dentro del peso comercial) afectó la longitud de los cuernos uterinos, el cuerpo uterino y el cuello uterino. Los ovarios con cuerpo lúteo presentaron mayor volumen y peso que aquellos con solo folículos. Aunque las medidas uterinas en la fase lútea aumentaron, la etapa del ciclo no afectó la morfometría uterina. El número promedio de anillos cervicales fue de 5,0, independientemente del peso o la raza. Los animales mestizos presentaron un primer anillo cervical más alto. La edad no influyó en el número, altura o distancia entre anillos cervicales. La desviación de la alineación normal del cuello uterino se registró en el 14,29 % de los animales, con mayor ocurrencia en el ganado Nelore; la desviación del eje de la mediana fue la más común (30%). Este estudio enfatiza varios parámetros que influyen en la morfometría del sistema reproductor de las hembras en el ganado Nelore y sus cruces, lo que podría ser crucial para implementar técnicas de biotecnología reproductiva más adecuadas a las características morfológicas de las razas cebú.

Pain management in cervical cancer.

Cervical cancer (CC) occupies the second place in incidence and mortality among women in México. Despite this, Cervical Cancer continues to have a late diagnosis which leads to a high rate of complications. Pain represents the most feared and disabling symptom, being present in up to 86% of patients with advanced disease. The approach to managing pain in this population has not been studied and described to a full extent. In addition, there is a pressing need to provide concise recommendations to promote adequate pain control. We performed a review of the literature in CC and had experts in the field of pain management evaluate the evidence found. We then issued relevant recommendations on pharmacology and interventional pain management. Thus, the approach to pain management must be comprehensive and individualized, considering the timely and appropriate use of pharmacologic treatment as well as interventional procedures.

Principales indicadores del Programa de Diagnóstico Precoz del Cáncer Cervicouterino en un hospital de Santiago de Cuba

Introducción: El cáncer cervicouterino ocupa el tercer lugar como causa de defunción por neoplasias malignas a nivel mundial, afectando principalmente a los países de ingresos bajos y medianos. Hacia el 2020 se estimó una incidencia de 604 000 nuevos casos. Objetivo: Caracterizar los principales indicadores hospitalarios del Programa de Diagnóstico Precoz del Cáncer Cervicouterino. Métodos: Se realizó un estudio observacional, descriptivo y transversal, que permitió caracterizar los principales indicadores hospitalarios del Programa en el Servicio de Patología de Cuello del Hospital General Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, de enero del 2020 a diciembre del 2022. La población de estudio estuvo constituida por 443 mujeres. Los datos recopilados fueron analizados mediante técnicas de estadística descriptiva, expresándose en frecuencia y porcentajes. Resultados: De las mujeres estudiadas, 60,9 % presentaron lesión intraepitelial cervical de alto grado de malignidad, con 32,6 % positivo a cáncer cervicouterino. El porcentaje global de pruebas citológicas no útiles fue de 2,07 y sin células de la zona de transformación, de 4,01; ambos indicadores de calidad. Existió una alta significación en cuanto a la tasa de cobertura global de las mujeres en riesgo (K=0,615), demostrando que los resultados de la citología reflejan en gran medida los diagnósticos de la histología, con una buena concordancia. Conclusiones: La prueba citológica cérvico-vaginal sigue siendo el método diagnóstico de mayor valor para detectar neoplasia intraepitelial cervical y carcinoma en estadio precoz en grandes masas de población.

Introduction: Cervical cancer is the third leading cause of death from malignancies worldwide, affecting mainly low- and middle-income countries. By 2020 an incidence of 604,000 new cases was estimated. Objective: To characterize the main hospital indicators of the Cervical Cancer Early Diagnosis Program. Methods: An observational, descriptive and cross-sectional study was carried out to characterize the main hospital indicators of the Program in the Neck Pathology Service of the General Hospital Dr. Bruno Zayas Alfonso of Santiago de Cuba, from January 2020 to December 2022. The study population consisted of 443 women. The data collected were analyzed using descriptive statistic techniques, expressed in frequency and percentages. Results: Of the women studied, 60.9 %had cervical intraepithelial lesion of high degree of malignancy, with 32.6 % positive for cervical cancer. The overall percentage of useless cytological tests was 2.07 and no cells from the processing zone was 4.01, both quality indicators. There was a high significance in terms of the overall coverage rate of women at risk (K=0.615), showing that the results of the cytology largely reflect the diagnosis of histology, with a good agreement. Conclusions: Cervical-vaginal cytology remains the most valuable diagnostic method for detecting cervical intraepithelial neoplasm and early-stage carcinoma in large populations

Guided coronally advanced flap to treat gingival recession: Digital workflow and case report.

BACKGROUND: The inherently technique-sensitive nature of periodontal plastic procedures demands a significant level of skill and expertise. The incorporation of three-dimensional (3D) printing technologies emerges as a potential strategy to optimize and simplify surgical procedures. This case report describes the digital workflow and presents the clinical outcomes achieved using a guided coronally advanced flap for the treatment of a single gingival recession (GR). METHODS AND RESULTS: A female patient with a gingival recession type 1 (RT1 B-) defect on the mandibular second left premolar underwent successful treatment using a guided coronally advanced flap (g-CAF) and de-epithelized connective tissue graft (CTG). The digital planning included intraoral scanning of the mandible and hard palate using an intraoral scanner, with resulting polygon format (PLY) files exported for virtual model creation. The CAF guide was meticulously designed to orient horizontal and vertical incisions at the papillae base adjacent to the GR defect. For the donor site, a guide was specifically created, positioning the graft area 2 mm apically to the premolars' gingival margins. The delineation of this area involved two horizontal and vertical incisions, meticulously based on the dimensions of the GR. The digitally designed guides were then 3D-printed using a surgical guide-specific resin, contributing to the precise execution of the innovative surgical approach. Complete root coverage was achieved. CONCLUSION: This case report demonstrates that g-CAF can be a promising approach for the treatment of single GR. HIGHLIGHTS: Why is this case new information? To the best of the authors' knowledge, this is the first manuscript to report a guided procedure for the treatment of gingival recession. This report provides the digital workflow for the fabrication of a guide to perform the coronally advanced flap for single recession defects. What are the keys to successfully manage this case? It is necessary to adequately scan the recession defect area and palate. Properly not only design the guide using specific software but also print it. The guide has to be stable when in position for the surgical procedure. What are the primary limitations of this technique? This guide was designed to help surgeons during the incisions. However, it does not provide aid to split and release the flap and suture.

De-escalation of surgical radicality for non-fertility preserving management in patients with early-stage cervical cancer: a systematic review.

OBJECTIVE: We sought to evaluate the oncologic outcomes of simple hysterectomy in patients with low-risk early-stage cervical cancer (tumors ≤2 cm with limited stromal invasion). METHODS: This study was registered in PROSPERO (registration number CRD42023433840) following the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) checklist. MEDLINE (through Ovid), EmMBASEbase, and Cochrane Central Register of Controlled Trials were searched from inception until June 2023. Randomized controlled trials and observational studies with two arms of comparison (simple hysterectomy with lymph node assessment vs radical hysterectomy with lymph node assessment) in patients with low-risk early-stage cervical cancer were considered. RESULTS: The search identified 1270 articles; eighteen studies were considered potentially eligible after removing duplicates, and four met the selection criteria. Three studies were randomized controlled trials, and the other was a retrospective cohort study. In total, 981 patients were included. There were 485 (49.4%) and 496 (50.6%) patients in the simple hysterectomy and radical hysterectomy groups, respectively. Simple hysterectomy with lymph node assessment was not associated with a higher risk of death at 5 years (RR 0.98, 95% CI: 0.31 to 3.10; I2=0%, two randomized controlled trials, 141 patients, for an absolute risk reduction of zero percentage points [95% CI -9.0 to 9.0]), pelvic recurrence at 3 years (97.5% and 97.8% for simple hysterectomy and radical hysterectomy, respectively, p=0.79), and overall recurrence at 3 years (95 %% and 100% for simple hysterectomy and radical hysterectomy, respectively, p=0.30). CONCLUSION: Simple hysterectomy with lymph node evaluation for low-risk early-stage cervical cancer is not associated with a detrimental effect on oncologic outcomes and has a better morbidity profile.

Reflexiones sobre el cáncer de cérvix y la salud pública / Reflections on Cervical Cancer and Public Health

En este artículo tratamos de mostrar la actual realidad y problemática del cáncer de cuello uterino en la salud pública. Su repercusión en la población femenina desde temprana edad y el plan de acción para su control como política a largo plazo para disminuir su mortalidad

In this article we try to show the current reality and problems of cervical cancer in public health. Its impact on the female population from an early age and the action plan for its control as a long-term policy to reduce mortality

The impact of clinical presentation, presence of SIRS and organ dysfunction on mortality in bitches with pyometra / O impacto da apresentação clínica, presença de SIRS e disfunção de órgãos em cadelas com piometra

This retrospective study evaluated the impact of the clinical presentation of pyometra on the morbidity and mortality of the affected bitches. The medical records of 47 bitches surgically treated for pyometra between May and December 2017 were evaluated. The admission data were analyzed to classify the animals according to the clinical presentation of pyometra, presence of systemic inflammatory response syndrome (SIRS) and organic dysfunctions (cardiovascular, neurological, renal, and hemostatic). The outcomes were recorded for up to 14 days. The overall mortality rate was 13%. Open and closed pyometra were identified in 62% (n= 29) and 38% (n= 18) of the cases, respectively. The SIRS was present in 44 (94%) bitches, and 27 (57%) had at least one organ dysfunction. The most prevalent dysfunction was hemostatic, followed by neurological, cardiovascular, and renal dysfunction. The clinical presentation of pyometra and the presence of SIRS did not correlate with each other, or with the presence of organ dysfunction and mortality. However, cumulative organ dysfunction (r=0.532, P=<0.001) and the presence of neurological (r= -0.371; P=0.012) and renal dysfunction (r=0.303; P=0.041) were correlated with mortality. Thus, the identification of organ dysfunction through physical examination and routine laboratory analysis proved to be more effective in identifying and predicting the critically ill patients than the SIRS criteria or clinical presentation of the disease.

O objetivo deste estudo retrospectivo foi avaliar o impacto da apresentação clínica da piometra na morbimortalidade das cadelas afetadas. Foram avaliados os registros clínicos de 47 cadelas tratadas cirurgicamente para piometra entre maio e dezembro de 2017. Os dados recolhidos na admissão foram analisados para classificar os animais quanto à apresentação clínica da piometra, presença de critérios da Síndrome da Resposta Inflamatória Sistêmica (SRIS) e disfunções orgânicas - cardiovascular, neurológica, renal e hemostática. Foi registrado o desfecho durante 14 dias. A mortalidade global foi de 13%. Piometra aberta e fechada foram identificadas em 62% (n= 29) e 38% (n= 18) respectivamente. SRIS esteve presente em 44 (94%) cadelas e 27 (57%) tiveram pelo menos uma disfunção orgânica. A disfunção mais prevalente foi a hemostática, seguida da neurológica, cardiovascular e renal. A apresentação clínica da piometra e a presença de SRIS não se correlacionaram entre si ou com presença de disfunção orgânica e mortalidade. No entanto, a quantidade de disfunções orgânicas (r=0.532, P=<0.001) e a presença das disfunções neurológica (r= -0.371; P=0.012) e renal (r=0.303; P=0.041) foram correlacionados com mortalidade. Assim, a identificação de disfunções orgânicas através do exame físico e análises laboratoriais de rotina mostrou-se mais eficaz na identificação e previsão de pacientes críticos do que os critérios de SRIS ou a apresentação clínica da doença.

Prevalencia y factores de riesgo de la neoplasia intraepitelial anal en pacientes con lesión intraepitelial cervical de alto grado / Prevalence and risk factors for anal intraepithelial neoplasia in patients with high- grade cervical intraepithelial lesion

Resumen OBJETIVO: Determinar la prevalencia de alteraciones en la citología anal, infección anal por virus del papiloma humano y en la neoplasia intraepitelial anal; además, explorar los factores de riesgo y los serotipos asociados en pacientes con lesión intraepitelial cervical de alto grado, a partir de la hipótesis de que esta población tiene mayor riesgo de lesiones precursoras o cáncer anal. MATERIALES Y MÉTODOS: Estudio observacional, descriptivo y transversal, con componente analítico, efectuado en pacientes con diagnóstico de lesión intraepitelial cervical de alto grado (LIEAG) en dos instituciones de salud: una privada y otra pública de Bogotá, atendidas entre enero de 2017 y febrero de 2018. Se efectuó un muestreo no probabilístico, por conveniencia. RESULTADOS: Se incluyeron 119 participantes, en 4 de ellas se evidenció, en la citología anal, el hallazgo de células anormales en el tejido que reviste la parte exterior del cuello uterino. Se encontraron 14 anoscopias anormales que dieron una prevalencia de neoplasia intraepitelial anal del 6.7%. Siete eran neoplasia intraepitelial anal de bajo grado y una de alto grado. Se encontró infección por VPH anal en 45 participantes (37.8%) y se detectaron genotipos de VPH-AR en 29 participantes (24.4%). Más de 3 compañeros sexuales, más de 3 hijos y tener menos de 21 años antes del primer embarazo tuvieron un valor de p < 0.05 que confiere mayor riesgo de infección por VPH anal. CONCLUSIÓN: Es importante establecer en Colombia protocolos para la detección de la neoplasia intraepitelial anal en grupos de alto riesgo, como las pacientes con neoplasia intraepitelial cervical o cáncer de cuello uterino, e incentivar el adiestramiento en la anoscopia de alta resolución en especialistas relacionados con el diagnóstico de patología anogenital.

Abstract OBJECTIVE: To determine the prevalence of alterations in anal cytology, anal human papillomavirus infection, and anal intraepithelial neoplasia, and to explore the risk factors and associated serotypes in patients with high-grade cervical intraepithelial lesion, based on the hypothesis that this population is at higher risk for precancerous lesions or anal cancer. MATERIALS AND METHODS: Observational, descriptive, cross-sectional study, with analytical component, performed in patients diagnosed with high-grade cervical intraepithelial lesion (HG-CIL) in two health institutions: one private and one public in Bogota, visited between January 2017 and February 2018. A non-probabilistic sampling was performed, by convenience, with a sample calculated in 124 patients. RESULTS: 119 participants were included, in 4 of them it was evidenced in the anal cytology, the finding of abnormal cells in the tissue lining the outside of the cervix. Fourteen abnormal anoscopies were found, giving a prevalence of anal intraepithelial neoplasia of 6.7%. Seven were low-grade anal intraepithelial neoplasia and one was high-grade. Anal HPV infection was detected in 45 participants (37.8%) and HR-HPV genotypes were detected in 29 participants (24.4%). More than 3 sexual partners, more than 3 children and being younger than 21 years before first pregnancy had a p-value < 0.05 conferring an increased risk of anal HPV infection. CONCLUSION: It is important to establish protocols in Colombia for the detection of anal intraepithelial neoplasia in high-risk groups, such as patients with cervical intraepithelial neoplasia or cervical cancer, and to promote training in high-resolution anoscopy in specialties related to the diagnosis of anogenital pathology.

Factores de riesgo del cáncer de cérvix en pacientes atendidas en un consultorio médico

Introducción: El cáncer de cérvix es un grave problema de salud que puede prevenirse con diagnósticos tempranos y la participación activa de las mujeres y profesionales de la salud. Objetivo: Determinar la asociación entre factores de riesgo y la aparición del cáncer de cérvix en mujeres procedentes del Consultorio Médico no. 7 del área del Policlínico Docente Julio Castillo Álvarez, en Chambas, Ciego de Ávila. Materiales y métodos: Se realizó un estudio analítico retrospectivo con 18 mujeres entre 25 y 60 años con diagnóstico previo de cáncer de cérvix, pertenecientes al Consultorio Médico no. 7, que fueron atendidas en el Hospital Provincial General Docente Roberto Rodríguez, de Morón. Resultados: Solo el 13 % de las participantes mencionaron gestaciones prematuras, y el 37,0 % reportó infección vaginal. El embarazo en la adolescencia fue el factor más común, con un 55,6 % de las mujeres afectadas. La mayoría de las mujeres (92,6 %) habían tomado anticonceptivos orales. Conclusiones: Los factores de riesgo identificados incluyen el primer coito antes de los 15 años y el hábito tabáquico, presentes en una franca minoría. El embarazo en la adolescencia y la ingestión de anticonceptivos orales fueron los más referidos.

Introduction: Cervical cancer is a serious health problem that can be prevented with early diagnoses and the active participation of women and health professionals. Objective: To determine the association of risk factors and the onset of cervical cancer in women from Doctor's office #7 of the Teaching Polyclinic Julio Castillo Alvarez area, in Chambas, Ciego de Avila. Materials and methods: A retrospective, analytical study was carried out with 18 women aged between 25 and 60 years, with previous diagnosis of cervical cancer, and belonging to the Doctor's Office # 7, who were treated at the Provincial General Teaching Hospital Roberto Rodríguez, in Morón. Results: Only 13% of the participants mentioned premature gestations and 37.0 reported vaginal infection. Teenage pregnancy was the most common factor, with 55.6% of women affected. Most of women (92.6%) had taken contraceptives. Conclusions: The risk factors identified include the first intercourse before the age of 15 and smoking, present in a clear minority. Pregnancy in adolescence and ingestion of oral contraceptives were the most mentioned.

Clinical and uterine cervix characteristics of women with Mycoplasma and Ureaplasma in genital discharge

SUMMARY OBJECTIVE: The objective of this study was to assess the clinical and uterine cervix characteristics of patients displaying vaginal discharge with positive results for Mycoplasma sp. and/or Ureaplasma spp. METHODS: An analytical cross-sectional study involving women aged 18-45 years was conducted. Microbiological assessments included Ureaplasma and Mycoplasma cultures, as well as human papillomavirus hybrid capture using ecto and endocervix swabs. All tests were two-tailed, and significance was set at p<0.05. RESULTS: Among 324 women, Ureaplasma prevalence was 17.9%, and Mycoplasma prevalence was 3.1%. The Ureaplasma-positive group exhibited a higher frequency of urinary tract infections (39.1 vs. 19%, p=0.002) and human papillomavirus (39.7 vs. 12.8%, p≤0.001) compared with controls. The Mycoplasma-positive group showed a higher frequency of non-contraceptive use compared with controls (66.2 vs. 30.0%, p=0.036). Abnormal colposcopic findings were more prevalent in the Mycoplasma/Ureaplasma-positive group than in controls (positive: 65% vs. control: 35%, p=0.001). Pap smear findings did not differ between the groups. CONCLUSION: Ureaplasma spp. was associated with urinary tract infections and human papillomavirus, while the presence of Mycoplasma sp. was linked to reduced contraceptive use. When analyzing both pathogens together, a higher frequency of abnormal colposcopic findings was observed, with no difference in cytological findings in the positive group.

Validación de la técnica de ganglio centinela en cáncer de cuello uterino en el Hospital de la Mujer / Validation of the sentinel lymph node technique in cervical cancer at the Women's Hospital / Validação da técnica do linfonodo sentinela em câncer de colo do útero no Hospital da Mulher

Introducción: el cáncer de cuello (CC) uterino representa un problema de salud pública. En Uruguay ocupa el tercer lugar en incidencia en mujeres, provocando 133 fallecimientos anuales. La afectación ganglionar es uno de sus principales factores pronósticos y condiciona el tratamiento. El ganglio centinela (GC) en estadios precoces de cáncer cervicouterino es una técnica segura que permite una adecuada estadificación y reduce la morbilidad asociada a la linfadenectomía convencional. Objetivo: validar la utilización de la técnica de la biopsia GC en estadios precoces de CC como estándar de tratamiento para la detección de metástasis ganglionares en el Hospital de la Mujer. Material y método: se realizó un estudio prospectivo, longitudinal, de casos. Se incluyó a 30 usuarias con CC en estadios iniciales, en el período comprendido entre enero de 2018 y noviembre de 2022. La marcación se realizó con tecnecio 99m (99mTc). En el mismo acto quirúrgico se realizó la linfadenectomía pélvica sistemática. Resultados: se detectó GC de forma bilateral en 29 de 30 pacientes. Con una tasa de detección por región de 98,3%. En cinco pacientes se detectaron GC metastásicos, no encontrando ganglios no centinela positivos. Una de ellas correspondió a una micrometástasis detectada por ultraestadificación. La sensibilidad fue de 100%: IC95% (56,55 -100) con VPN 100% IC95% (86,68 - 100). Conclusiones: de acuerdo con los resultados arrojados por el estudio, el equipo interdisciplinario del Hospital de la Mujer está en condiciones de utilizar la biopsia de GC de cérvix como estándar de tratamiento en el CC uterino en estadio precoz.

Introduction: Cervical cancer (CC) is a public health problem. In Uruguay, it ranks third in incidence in women, causing 133 deaths annually. Lymph node involvement is one of its main prognostic factors and determines treatment. The sentinel lymph node (SLN) in early stages of cervical cancer is a safe technique that allows for adequate staging and reduces morbidity associated with conventional lymphadenectomy. Objective: To validate the use of the SLN biopsy technique in early stages of CC as the standard treatment for detecting lymph node metastases at the Women's Hospital. Method: A prospective, longitudinal case study was conducted. Thirty patients with early-stage cervical cancer between January 2018 and November 2022 were included in the study. The marking was done with Tc99. Systematic pelvic lymphadenectomy was performed in the same surgical procedure. Results: Sentinel lymph nodes were detected bilaterally in 29 out of 30 patients. With a detection rate per region of 98.3%, metastatic SLNs were detected in 5 patients, with no positive non-sentinel nodes found. One of them corresponded to a micrometastasis detected by ultra-staging. Sensitivity was 100% (95% CI 56.55,100) with a negative predictive value of 100% (95% CI 86.68, 100). Conclusions: According to the results of the study, the interdisciplinary team at the Women's Hospital is in a position to use cervical SLN biopsy as the standard treatment for early-stage cervical cancer.

Introdução: O câncer do colo do útero (CCU) representa um problema de saúde pública. No Uruguai, ocupa o terceiro lugar em incidência em mulheres, causando 133 mortes por ano. O acometimento dos linfonodos é um dos principais fatores prognósticos e condiciona o tratamento. O linfonodo sentinela (LS) em estágios iniciais do câncer do colo do útero é uma técnica segura que permite o estadiamento adequado e reduz a morbidade associada à linfadenectomia convencional. Objetivo: Validar o uso da técnica de biópsia por LS em estágios iniciais do CCU como tratamento padrão para a detecção de metástases linfonodais no Hospital da Mulher. Materiais e métodos: Foi realizado um estudo de caso prospectivo e longitudinal. Trinta usuárias com LS em estágio inicial foram incluídas no período de janeiro de 2018 a novembro de 2022. A marcação foi realizada com Tc99. A linfadenectomia pélvica sistemática foi realizada no mesmo ato cirúrgico. Resultados: O LS foi detectado bilateralmente em 29 das 30 usuárias, com uma taxa de detecção por região de 98,3%. Em 5 pacientes foram detectados LS metastáticos e não foram encontrados nódulos não-sentinela positivos. 1 deles correspondia a uma micrometástase detectada por ultrassonografia. A sensibilidade foi de 100% CI 95% (56,55,100) com NPV 100% CI 95% (86,68, 100). Conclusões: Com base nos resultados do estudo, a equipe interdisciplinar do Hospital da Mulher está em condições de usar a biópsia de LS cervical como padrão de tratamento no câncer cervical em estágio inicial.

The top hat procedure does not impact the management of women treated by LEEP in cervical cancer screening

Abstract Objective: To describe Top-hat results and their association with margin status and disease relapse in a referral facility in Brazil. Methods: A retrospective study of 440 women submitted to LEEP to treat HSIL, in which 80 cases were complemented immediately by the top hat procedure (Top-hat Group - TH). TH Group was compared to women not submitted to Top-hat (NTH). The sample by convenience included all women that underwent LEEP from January 2017 to July 2020. The main outcome was the histological result. Other variables were margins, age, transformation zone (TZ), depth, and relapse. The analysis used the Chi-square test and logistic regression. Results: The TH Group was predominantly 40 and older (NTH 23.1% vs. TH 65.0%, p<0.001). No difference was found in having CIN2/CIN3 as the final diagnosis (NTH 17.0% vs. TH 21.3%, p=0.362), or in the prevalence of relapse (NTH 12.0% vs. TH 9.0%, p=0.482). Of the 80 patients submitted to top hat, the histological result was CIN2/CIN3 in eight. A negative top hat result was related to a negative endocervical margin of 83.3%. A CIN2/CIN3 Top-hat result was related to CIN2/CIN3 margin in 62.5% (p=0.009). The chance of obtaining a top hat negative result was 22.4 times higher (2.4-211.0) when the endocervical margin was negative and 14.5 times higher (1.5-140.7) when the ectocervical margin was negative. Conclusion: The top hat procedure did not alter the final diagnosis of LEEP. No impact on relapse was observed. The procedure should be avoided in women of reproductive age.

Is the colposcopic lesion size a predictor of high-grade lesions in young patients?

ABSTRACT Objective: This study aimed to evaluate whether severity changes with colposcopic lesion size, regardless of age. Methods: This retrospective comparative study reviewed the records of 428 women with altered cytopathology reports who were directed by primary health care. Only those women with colposcopic alterations were evaluated (n=411). Histopathological analyses were restricted to patients who underwent excisional treatment (n=345). According to their age, they were grouped into the following: <21, 21-24, 25-35, and >35 years, and also, ≤24 and ≥25 years. The cytopathological, colposcopic, and histopathological findings were grouped according to severity. Lesion size was subjectively assessed from the colposcopic drawing recorded in the chart and according to the number of quadrants of the total cervical surface affected by colposcopic alterations in the transformation zone. Statistical significance was set at p<0.05. Results: The evaluations suggested that the lesion size was directly related to the severity of the cytopathology, colposcopy, and histopathology reports for the age groups ≤24 or ≥25 years. We observed associations between lesion size and severity of the cytopathology (≤24 years, p=0.037) and histopathology (≥25 years, p=0.003) findings. Conclusion: The size of the lesion was directly related to the severity of the histopathological lesion in patients aged ≥25 years and cytopathological in patients aged ≤24 years.

Association between Cervical Cancer and Dietary Patterns in Colombia.

Cervical cancer is a global public health problem. It is the second leading cause of death among women of childbearing age worldwide. Several factors, including diet, have been shown to influence the risk of persistent HPV infection and tumor progression. This paper determines the relationship between dietary patterns and cervical cancer. It is an ecological study of multiple groups, based on two national sources: the High-Cost Account and the National Survey of Nutritional Situation of Colombia of 2015. The population consisted of 3472 women aged 35 to 64. The incidence of cervical cancer was used as the dependent variable while the independent variables included food consumption according to established patterns, area of residence, age, physical activity, and BMI, among other variables. The statistical analysis performed through associations between variables was evaluated by multiple linear regression using R2. 38.9% of the evaluated population belonged to the first quartile of wealth, and 76.5% resided in the municipal capital. The incidence of cervical cancer in Colombia was associated with being affiliated to a state-subsidized health regime and having diabetes mellitus. A conservative eating pattern, as well as belonging to a rural area, are evidenced as protective factors. These results invite the need to encourage public policies and promote healthy lifestyles.

Treatment of single gingival recessions using biofunctionalized collagen matrix: A case series.

BACKGROUND: Connective tissue graft substitutes have been used widely to overcome autogenous graft limitations. Nevertheless, they do not provide comparable results in the treatment of periodontal and peri-implant soft tissue defects. Based on the principles of tissue-engineered materials, injectable platelet-rich fibrin (i-PRF) has been combined with collagen matrices (CMs) to enhance their clinical efficacy. To the best of our knowledge, this is the first case series demonstrating the use of i-PRF for the biofunctionalization of a volume-stable collagen matrix (VCMX) as an adjunct to coronally advanced flap (CAF) to treat single gingival recession (GR) defects. METHODS & RESULTS: The study included 10 patients. Bleeding on probing, probing depth, GR height, clinical attachment level, esthetics, and dentin hypersensitivity were evaluated. After 6 months, a significant GR reduction (RecRed: 2.15 ± 0.7 mm; p = 0.005) and percentage of root coverage (% RC) of 81.13% were observed. Additionally, 40% of the sites showed complete root coverage. Gingival thickness increased 0.64 mm. Patient-centered evaluations demonstrated dentin hypersensitivity and esthetics improvements by the end of follow-up. CONCLUSION: VCMX biofunctionalized with i-PRF associated with CAF technique showed promising clinical outcomes in the treatment of single RT1 GR defects.

Evaluación de la dilatación cervical en simuladores comparada con una herramienta visual: estudio aleatorizado / Cervical dilation assessment in simulators compared to a visual tool: A randomized study / Avaliação da dilatação cervical em simuladores comparada a uma ferramenta visual: estudo randomizado

Objetivo: comprobar la tasa de evaluación correcta mediante la comparación visual directa de las medidas de dilatación cervical en modelos de cuello uterino de consistencia dura. Método: estudio aleatorizado abierto con 63 estudiantes de obstetricia a los que se les asignó usar o no la comparación visual directa con una guía de dilatación. Los estudiantes estimaron de forma ciega la dilatación cervical en simuladores con diferentes dilataciones. El resultado primario fue la tasa de evaluación correcta. Resultados: los estudiantes realizaron 441 pruebas. Se observó una mayor tasa de evaluación correcta en el grupo experimental que en el grupo control (47,3% versus 27,2%; p < 0,001; Odds Ratio = 2,41; intervalo de confianza del 95% = 1,62-3, 58). Conclusión: la comparación visual directa aumentó la precisión de la evaluación de la dilatación cervical en modelos de simulación de cuello, lo que podría ser beneficioso en el entrenamiento de laboratorio.

Objective: to verify the correct assessment rate when using direct visual comparison in the cervical dilation measures in hard-consistency cervix simulation models. Method: an open-label and randomized study conducted with 63 Obstetrics students that were designated either to use direct visual comparison in a dilation guide or not. The students estimated cervical dilation blindly in simulators with different dilations. The primary outcome was the correct assessment rate. Results: the students performed 141 tests. A higher correct assessment rate was found in the Experimental Group than in the Control Group (47.3% versus 27.2%; p<0.001; Odds Ratio = 2.41; 95% Confidence Interval = 1.62-3.58). Conclusion: the direct visual comparison increased precision of the cervical dilation assessment in cervix simulation models, with the possibility of being beneficial in laboratory training.

Uterine collision tumor. Case report and review of the literature / Tumor de colisión de útero. Reporte de caso y revisión de la literatura

Objectives: To report the case of a patient with a uterine collision tumor and to conduct a review of the literature. Material and methods: A 76-year-old patient who presented to the national cancer referral center in Bogota (Colombia), where she was diagnosed with a uterine collision tumor consisting of a seroustype endometrial adenocarcinoma and a cervical adenosarcoma. The patient underwent surgical treatment followed by chemotherapy and supplemental radiotherapy, and died 16 months later. A search was conducted in the Medline via PubMed and Embase databases, including reports and case series of women with a diagnosis of uterine collision tumor, with retrieval of information regarding diagnosis, treatment and prognosis. A narrative summary of the findings was made. Results: The search identified 36 titles, of which 14 studies with 17 patients were included. The most frequent histopathological diagnosis was endometrial adenocarcinoma and high and low grade endometrial sarcoma (47 %). Primary treatment was surgery and adjuvant treatment with chemotherapy and radiotherapy (15 %) was performed in close to 50 % of cases. One-year survival was 75 %. Conclusions: No cases of uterine collision tumors with the histopathology or in the location of the reported case were found in the literature. If this reported case is taken into account, 2-year mortality is 28 %. Further studies to describe the immunohistochemistry, treatment and prognosis of this condition are needed.
