Justificativas e Objetivos: Câncer de colo de útero é considerado um problema de saúde pública mundial. Seu diagnóstico é realizado através do exame citopatológico (EC) e seu desenvolvimento relacionado à infecção pelo papilomavírus humano (HPV). Este estudo objetiva avaliar o perfil de mulheres atendidas em centros de referência em saúde de Porto Alegre, Rio Grande do Sul, assim como a relação de alterações observadas ao EC com presença do HPV. Métodos: Estudo transversal realizado em mulheres atendidas em unidades básicas de saúde e um ambulatório de referência de hospital público terciário, no período de julho de 2014 a janeiro de 2017. Coletaram-se amostras representativas da endo/ectocérvice para realização do EC e investigadas quanto à presença molecular do HPV. Resultados: Foram analisadas 169 mulheres com idade média entre 31 e 40 anos, das quais 125 (74%) informaram que a sexarca ocorreu na faixa de 15-20 anos e 37,9% relatou ter tido de três a cinco parceiros sexuais. Em relação ao EC, 71 (42%) apresentaram resultado negativo para lesão intraepitelial ou malignidade e 98 (58%) alguma anormalidade de células escamosas: 20 (11,8%) atipias; 22 (13%) lesão intraepitelial escamosa de baixo grau e 56 (32,6%) lesão intraepitelial de alto grau (HSIL). Cinquenta (29,6%) apresentaram positividade para HPV, destas 56,4% foram diagnosticadas com HSIL (p<0,01). Conclusão: Os resultados revelam alta frequência de HPV em amostras com alterações citopatológicas, em mulheres jovens e com grau de exposição ao HPV, reforçando a importância do papel da sua identificação precoce na investigação da carcinogênese cervical.(AU)

Background and Objectives: Cervical cancer is considered a worldwide public health problem. Its diagnosis is made through cytopathological examination and its development related to human papillomavirus (HPV) infection. This study aims to evaluate the profile of women treated at reference health centers in Porto Alegre, Rio Grande do Sul, as well as the relation of changes observed to cytopathological examination with the presence of HPV. Methods: This is a cross-sectional study carried out in women treated at basic health units and a referral clinic of a public tertiary hospital, from July 2014 to January 2017. Representative samples of the endo/ectocervix were collected to perform the cytopathological examination and investigated for the molecular presence of HPV. Results: 169 women with mean age between 31 and 40 years were analyzed, of whom 125 (74%) reported that the onset of sexual activity occurred in the 15-20 years age group, and 37.9% reported having had three to five sexual partners. In relation to cytopathological examination, 71 (42%) had a negative result for intraepithelial lesion or malignancy and 98 (58%) some squamous cell abnormality: 20 (11.8%) atypical; 22 (13%) low-grade squamous intraepithelial lesion and 56 (32.6%) high-grade intraepithelial lesion (HSIL). Fifty (29.6%) were positive for HPV, of which 56.4% were diagnosed with HSIL (p < 0.01). Conclusion: The results reveal a high frequency of HPV in samples with cytopathological changes, in young women and with a degree of exposure to HPV, reinforcing the importance of the role of its early identification in the investigation of cervical carcinogenesis.(AU)

Menopausal status is associated with a high risk for residual disease after cervical conization with positive margins.

BACKGROUND: We aimed to determine demographic and clinicopathological predictors for residual disease in women with cervical intraepithelial neoplasia (CIN 2/3) with endocervical cone margin involvement. METHODS AND FINDINGS: A cross-sectional study was conducted. The eligible patients were women who underwent hysterectomy as a treatment option after having a positive endocervical margin for CIN 2/3 in cervix conization specimens from 2000 to 2015. The patients were divided into two groups based on the persistence of CIN 2/3 and absence of CIN 2/3 in hysterectomy specimens. Demographic, clinical and histology information were collected in both groups. A total of 80 patients were eligible for the study; 37 (46.3%) had no persistence of CIN 2/3 and 43 (53.7%) had persistence of CIN 2/3 in the hysterectomy specimens. Demographic, clinical, and cone specimen characteristics, and a visible squamocolumnar junction and type of conization were analyzed as possible risk factors for the presence of residual lesions at hysterectomy, and none of these variables were associated with residual disease. Menopausal status was strongly associated with a high risk of persistent residual disease 81.2% (OR 4.9, CI 1.27-18.9), P = 0.014. In the multivariate analysis, only a menopausal status (P = 0.04) was associated with a high risk of persistent lesions. CONCLUSION: This analysis found that menopausal status exhibited an important association with persistent residual disease. Menopausal women with endocervical margin involvement exhibit a greater than 80% risk of persistent lesions.

Early Experience of Robotic Hysterectomy for Treatment of Benign Uterine Disease.

Objectives To demonstrate the initial experience of robotic hysterectomy to treat benign uterine disease at a university hospital in Brazil. Methods A cross-sectional study was conducted to review data from the first twenty patients undergoing robotic hysterectomy at our hospital. The surgeries were performed from November 2013 to August 2014, all of them by the same surgeon. The patients were reviewed for preoperative characteristics, including age, body mass index (BMI), indications for the hysterectomy and previous surgeries. Data of operative times, complications, postoperative pain and length of hospital stay were also collected. Results The total operating room time was 252.9 minutes, while the operative time was 180.7 minutes and the console time was 136.6 minutes. Docking time was 4.2 minutes, and the average undocking time was 1.9 minutes. There was a strong correlation between the operative time and the patient's BMI (r = 0.670; p = 0.001). The console time had significant correlation with the uterine weight and the patient's BMI (r = 0.468; p = 0.037). A learning curve was observed during docking and undocking times. Conclusion Despite its high cost, the robotic surgery is gaining more space in gynecological surgery. By the results obtained in our hospital, this surgical proposal proved to be feasible and safe. Our initial experience demonstrated a learning curve in some ways.

Resumo Objetivos O presente projeto visa à documentação da experiência inicial do Hospital de Clínicas de Porto Alegre na realização da histerectomia robótica. Métodos Um estudo transversal foi realizado a fim de revisar dados das primeiras vinte pacientes submetidas à histerectomia robótica em nosso hospital. As cirurgias foram realizadas no período de novembro de 2013 a agosto de 2014, e todas tiveram o mesmo cirurgião. Foram analisadas características pré-operatórias, incluindo idade, índice de massa corporal, cirurgias prévias abdominais, paridade, indicação da histerectomia. Dados referentes aos tempos operatórios, complicações, dor pósoperatória e tempo de internação pós-operatória também foram coletados. Resultados O tempo de sala total foi de 252,9 minutos, enquanto o tempo cirúrgico total foi 180,7 minutos, e o tempo de console foi 136,6 minutos. O tempo médio de docking foi 4,2 minutos; e o tempo médio de undocking foi 1,9 minutos. Foi observada forte correlação entre o tempo cirúrgico total e o índice de massa corporal da paciente (r = 0,670; p = 0,001). O tempo de console teve correlação significativa com o peso uterino e com o índice de massa corporal das pacientes (r = 0,468; p = 0,037). Foi observada curva de aprendizado nos tempos de docking e undocking. Conclusão Apesar do alto custo, a robótica vem ganhando espaço na cirurgia ginecológica. Pelos resultados obtidos no nosso hospital, a proposta provou ser factível e segura. Nossa experiência inicial demonstrou curva de aprendizado em alguns aspectos.

Tumor de células de Leydig do ovário associado a virilização em paciente na pós-menopausa / Ovarian Leydig cell tumor associated with virilization in postmenopausal patient

Tumores de células de Leydig são neoplasias de células esteroides e correspondem a menos de 0,5% dos tumores ovarianos. Ocorrem mais comumente na pós-menopausa e se apresentam com virilização em metade dos casos. Relatamos o caso de uma mulher de 53 anos com história de virilização. A investigação com ressonância magnética demonstrou altos níveis séricos de testosterona e um nódulo de 2 cm no ovário direito. A paciente foi submetida a ooforectomia bilateral, e a análise patológica confirmou o diagnóstico de tumor de células de Leydig do ovário direito. Um dia após a cirurgia, o nível sérico de testosterona se normalizou. Em quatro meses, a paciente apresentou nível sérico normal de testosterona e regressão parcial da alopecia. Em mulheres pós-menopáusicas com quadro de virilização progressiva, deve-se suspeitar de neoplasias ovarianas produtoras de andrógenos (AU)

Leydig cell tumors are tumors of the steroids cells and represent less than 0.5% of ovarian tumors. They occur most often in postmenopausal women and present with virilization in half of the cases. We report the case of a 53-year-old woman with virilization history. Magnetic resonance imaging showed high serum testosterone levels and a 2-cm nodule in the right ovary. The patient underwent bilateral oophorectomy, and the pathological analysis confirmed the diagnosis of Leydig cell tumor in the right ovary. The day after surgery, serum testosterone level was normalized. In four months, the patient had normal serum testosterone level and partial regression of alopecia. In postmenopausal women with progressive virilization, ovarian neoplasms producing androgens should be investigated (AU)

Randomized clinical trial comparing cold knife conization of the cervix with and without lateral hemostatic sutures.

OBJECTIVE: Compare blood loss during cold knife conization of the cervix with and without lateral hemostatic sutures in the cervical branches of the uterine arteries. DESIGN: Randomized clinical trial. SETTING: Hospital de Clínicas de Porto Alegre (HCPA). POPULATION: 102 patients that underwent cold knife conization. METHODS: Women that underwent cold knife conization of the cervix were randomized to undergo the procedure with or without lateral hemostatic sutures. PRIMARY OUTCOME MEASURE: blood loss measured in grams. SECONDARY OUTCOME MEASURES: operative time and postoperative intervention. Only the participants were blinded to group assignment. RESULTS: From March 2009 to August 2012, patients were randomly assigned to one of the study groups. There were no differences in amount of blood loss between patients that underwent the procedure with and without sutures (p = 0.39). Operative time was shorter in the group without suture (p = 0.020). There were no differences in intervention due to bleeding (p = 0.20). Blood loss was greater among menstruating women than for menopausal women (p = 0.011). There were no differences in amount of blood lost between smoking and nonsmoking patients (p = 0.082). CONCLUSIONS: Lateral hemostatic sutures do not affect the amount of intraoperative bleeding or the number of postoperative interventions. Their use is not necessary because they result in longer operative time, have a higher cost due to the use of suture material and pose the risk of ureter lesion in case the sutures are not placed at a lower position in the cervix.

Comparison of loop electrosurgical conization with one or two passes in high-grade cervical intraepithelial neoplasias.

The use of loop electrosurgical conization (LEC) for the treatment of large high-grade cervical intraepithelial neoplasias (CINs) is often associated with a difficult procedure that results in accidental sample fragmentation, thermal damage and sometimes the presence of positive margins. This study aims to compare LEC that removes the cervical cone in two blocks (anterior and posterior cervical lips - LEC2) with LEC performed with one pass of the loop (LEC1). In a randomized, controlled trial, patients that needed conization due to high-grade CIN were assigned to one of the techniques. There were no differences in terms of age, cone histopathological diagnosis, blood loss, vaginal injuries, stenosis of the cervical os and specimen artifacts. LEC2 required less hemostatic sutures. LEC2 showed no specimen fragmentation, while LEC1 did (0 vs. 5.9%; p = 0.10). As expected, LEC2 samples were heavier (p = 0.01), included a larger ectocervical area (p = 0.001) and, therefore, had a greater volume (p < 0.001) compared to LEC1 samples. The height of the LEC2 specimens was smaller than that of LEC1 specimens (p < 0.001). LEC2 yielded fewer cases of positive margins (12.7%) than LEC1 (33.3%; p = 0.021). We conclude that the LEC2 technique is an effective treatment choice: it is safe for the patient, with better outcomes regarding sample quality than LEC1. Further studies are encouraged regarding this procedure.
