Conhecimento para apoio aos profissionais responsáveis pelo diagnóstico de citologia anal: revisão narrativa e interpretação de critérios citomorfológicos

Resumo:Introdução:O câncer anal é uma patologia considerada rara, apesar de crescente na população. A citologia anal tem sido uma aposta para diagnosticar as alterações pré-neoplásicas, evitando a evolução ao câncer. Objetivos:I) Abordar aspectos de satisfatoriedade da amostra celular e revisar os critérios citomorfológicos dos achados benignos e malignos nos esfregaços de citologia anal. II) Tornar este artigo um instrumento de suporte aos profissionais de saúde que atuam no setor de Citopatologia vinculados ao Sistema Único de Saúde (SUS) ou à iniciativa privada. Métodos:Revisão narrativa, com busca nas bases PubMed, Science Direct e SciELO, de fevereiro a abril/2023. Desenvolvimento:A análise da literatura aponta para a aplicação da citologia anal para diagnóstico das alterações induzidas pelo Papilomavírus Humano (HPV) no canal anal. O rastreamento se baseia na semelhança ao controle do câncer de colo uterino e à história natural da doença, reconhecendo que as lesões precursoras evoluem ao câncer invasivo. Essa janela entre a lesão e o câncer abre espaço para detecção precoce. Oportunamente, a técnica pode diagnosticar agentes responsáveis por outras Infecções Sexualmente Transmissíveis (IST). Conclusão: Qualificar os laudos de diagnóstico citopatológico pode apoiar o cuidado desde a atenção primária. O intuito deste trabalho foi contribuir com o processo de aprendizagem dos profissionais da saúde e apoiar a saúde pública nas estratégias de garantia de cuidado às pessoas.

Microablative fractional radiofrequency for sexual dysfunction and vaginal Trophism: A randomized clinical trial.

OBJECTIVES: To evaluate Microablative Fractional Radiofrequency (MAFRF) as a possible option in treating vaginal atrophy. METHODS: This was a randomized, controlled clinical trial with postmenopausal women diagnosed with vaginal atrophy. The treatment consisted of three sessions of MAFRF, compared to vaginal estrogen administration and an untreated control group. Assessments occurred at baseline and 90 days. The primary endpoints were sexual function, evaluated by the Female Sexual Function Index (FSFI), and vaginal health, assessed by the Vaginal Health Index (VHI). Secondary outcomes included vaginal microbiota composition (Nugent score) and epithelial cell maturation (Maturation Value ‒ MV). RESULTS: One hundred and twenty women (40 in each group) were included. Concerning the FSFI, both groups, MAFRF (median 4.8 [3.6‒6.0]) and vaginal estrogen (mean 4.7 ± 1.1), experienced improved sexual desire when compared to the control group (median 3.6 [2.4‒4.8]). Regarding the total score of VHI, the authors observed an improvement in the mean of the MAFRF (23.7 ± 2.0) and vaginal estrogen groups (23.5 ± 1.9) when compared to the control (14.8 ± 2.9). The Nugent score was reduced in the MAFRF and estrogen groups (p < 0.01) compared to the control group. Lastly, the MV was modified after treatment with MAFRF (p < 0.01) and vaginal estrogen (p < 0.001). No differences existed between the MAFRF and vaginal estrogen groups in the studied variables. No adverse effects were reported following the MAFRF protocol. CONCLUSIONS: Radiofrequency was comparable in efficacy to estrogen administration for treating vulvovaginal atrophy. It deserves consideration as a viable option in managing this condition.

Chatbot, ChatGPT: artificial intelligence and/or business intelligence and/or robotic untruths, for now / Chatbot, ChatGPT: inteligência artificial e/ou inteligência comercial e/ou inverdades robotizadas, por enquanto

The authors, like most humans on the planet at all times, go through many profound transformations throughout their lives. Let's imagine hominids starting to master fire more than a million years ago. Inventing the wheel, writing, navigating the seas, inventing the light bulb, motor vehicles, Santos Dumont's plane, telex, teleradiography, and so many other things that for each era, it was unimaginable such an advance would be incorporated into daily of human life. Today, in 2023, we are facing a computerized conversation through the world wide web, the internet. For now, called artificial intelligence ­ AI, chatbot. How much will this technology add benefits in the health area? When will this technology spread untruths? How much will people blindly follow the information and experience huge gains and marked problems, side effects? In these dialogues with the various chatbots already being made available, free or with payment of monthly fees, can these computer programs, after several human-AI arguments, write that, for the situations presented in a given conversation, suicide is plausible conduct? The concerns of the authors are concerns that are valid in March 2023. The editorial tests conversations. And time will show us how to learn, teach, live together, and transform this artificial intelligence

Anal High-risk HPV and Liquid-based Cytology of Immunocompetent Brazilian Women with Genital High-risk HPV / HPV de alto risco e citologia em meio líquido de canal anal de mulheres brasileiras imunocompetentes com HPV genital de alto risco

Abstract Objective The purpose of this study was to compare the frequency of the occurrence of high-risk human papillomavirus (HPV) and abnormal anal cytology in immunocompetent women with and without HPV-induced genital lesions. Methods This analytical cross-sectional, observational study was conducted between July 2017 and December 2018 in a specialized outpatient clinic of a tertiary hospital in Fortaleza, CE. Fifty-seven immunocompetent women with and without genital intraepithelial lesions were assessed; they were divided into two groups: group 1 was comprised of women with HPV-associated genital lesions (n=26), and group 2 was comprised of those without HPV-associated genital lesions (n=31). Samples for liquidbased cytology and high-risk DNA-HPV polymerase chain reaction real-time tests were collected from the cervix and anus. All cases were evaluated using high-resolution anoscopy; biopsies were performed when required. The Fisher exact and chi-squared tests were applied for consolidated data in the contingency table, and the Student ttest and Mann-Whitney U-test for independent variables. Results Anal high-risk HPV infections were more frequent in group 1 (odds ratio [OR], 4.95; 95% confidence interval [CI], 1.34-18.3; p=0.012), along with concomitant highrisk HPV infections in the uterine cervix and the anus (OR 18.8; 95% CI, 2.20-160; p<0.001). The incidence of high-risk cervical HPV infection was associated with highrisk anal HPV infection (OR, 4.95; 95% CI, 1.34-18.3; p=0.012). There was no statistical difference concerning abnormal anal cytology or anoscopy between the groups, and no anal intraepithelial lesion was found in either group. Conclusion Immunocompetent women with HPV-associated genital lesions and high-risk cervical HPV were more likely to have high-risk anal HPV.

Impact of microablative fractional radiofrequency on the vaginal health, microbiota, and cellularity of postmenopausal women.

OBJECTIVES: We aimed to evaluate the effectiveness of microablative fractional radiofrequency (MAFRF) in the non-hormonal treatment of genitourinary syndrome of menopause. METHODS: We examined the cases of 55 postmenopausal women before and after treatment with regard to their vaginal health index (VHI), vaginal microbiota, vaginal pH, and cell maturation. Three applications of MAFRF were performed in the vagina/vaginal introitus. During the treatment, six vaginal smears were obtained and stained with the Papanicolaou stain for determining the degree of cell maturation and with Gram stain for classification of vaginal flora, as per the criteria of Spiegel and Amsel. For vaginal pH determination, pH indicator strips were applied against the vaginal wall. Statistical analysis was performed using SPSS for Windows (version 17.0). Data were reported as mean±standard deviation. The differences were analyzed using the statistical method of generalized estimation equations with autoregressive correlation structure "1" and robust standard errors. RESULTS: The mean age was 59.8±4.2 years, and the mean time of menopause was 15.4±4.5 years. After treatment, there was an increase in the percentage of Lactobacillus spp. (p<0.001). Consequently, there was a progressive decrease in vaginal pH during the treatment (p<0.001). Regarding cell maturation, there was a decrease in the percentage of parabasal cells (p=0.001) and an increase in the rate of superficial cells (p<0.001). Additionally, there was an improvement in the VHI index. The mean VHI values before and after treatment were 13.2±5.6 and 22.5±3.7, respectively (p<0.001). CONCLUSION: MAFRF treatment is well tolerated and leads to improvement in the vaginal microenvironment.

Management of Atypical Squamous Cell Cases: A Prospective Study of Women seen at a Private Health Service in Northeastern Brazil.

OBJECTIVE: To assess the management chosen by gynecologists after atypical squamous cells (ASCs) cytology results, and to evaluate the outcomes of these cases in Brazilian women. METHODS: A prospective observational study evaluated the initial management offered by the gynecologist in the case of 2,458 ASCs cytology results collected between January of 2010 and July of 2016. The outcomes of the cytology, high-risk human papilloma virus (HR-HPV) test and histology were compared in two subgroups: atypical squamous cells of undetermined significance (ASC-US) and atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (ASC-H). RESULTS: In many cases of ASC-US (36.97%) and ASC-H (40.50%), no clinical actions were taken. Cytology was the most frequent follow-up chosen, including for cases of ASC-H, which goes against the conduct recommended in the national guideline. In women over 30 years of age, the period of time elapsed between an ASC-US result and a new cytology was in 13.03 months, in disagreement with the national guideline recommendations (p < 0.0001). Negative for intraepithelial lesions or malignancy (NILM) cytologic (p = 0.0026) and histologic (p = 0.0017) results in the follow-up were associated with prior ASC-US, while negative results for ASC-H were cytologically (p < 0.0001) and histologically associated with high-grade squamous intraepithelial lesion (HSIL) (p < 0.0001). Two invasive cervical carcinomas (ICCs) were found in the follow-up for ASC-H, and there was a statistically significant association (p = 0.0341). A positive HR-HPV test was associated with ASC-H (p = 0.0075). CONCLUSION: The data suggest that even for a population of Brazilian women assisted at private clinics, the national guidelines recommendations for ASCs results are not followed.

OBJETIVO: Avaliar a conduta adotada por ginecologistas após resultados citológicos apresentando células escamosas atípicas (ASCs) e os desfechos destes casos em mulheres brasileiras. MéTODOS: Um estudo observacional prospectivo avaliou o manejo clínico inicial do ginecologista nos casos de 2.458 resultados citológicos apresentando ASCs coletados entre janeiro de 2010 e julho de 2016. Os respectivos desfechos citológicos, histológicos e de detecção do papilomavírus humano (HPV) foram comparados entre os subgrupos células escamosas atípicas de significado indeterminado (ASC-US) e células escamosas atípicas não podendo excluir lesão intraepitelial de alto grau (ASC-H). RESULTADOS: Nenhuma conduta foi adotada em 36,97% de citologias do tipo ASC-US e 40,5% do tipo ASC-H. A conduta mais escolhida foi a repetição da citologia, inclusive para acompanhamento de ASC-H, o que contraria as diretrizes nacionais. O tempo de realização de uma nova citologia para resultado do tipo ASC-US em mulheres com mais de 30 anos de idade foi de 13,03 meses, também em desacordo com as diretrizes (p < 0,0001). Resultados negativos para lesão intraepitelial ou neoplasia maligna (NILM), tanto citológicos (p = 0,0026) como histológicos (p = 0,0017), foram associados a ASC-US, enquanto que resultados negativos para lesões intraepiteliais escamosas de alto grau (HSILs), citológicos (p < 0,0001) e histológicos, foram associados a ASC-H (p < 0,0001). Dois carcinomas cervicais invasivos foram encontrados durante o acompanhamento para ASC-H e uma associação estatisticamente significante foi estabelecida (p = 0,0341). Um teste de HR-HPV positivo foi associado a ASC-H (p = 0,0075). CONCLUSãO: Os dados sugerem que mesmo para uma população de mulheres brasileiras atendidas em clínicas privadas, as recomendações das diretrizes clínicas nacionais para resultados citológicos apresentando ASCs não são seguidas.

Correlação entre vaginose bacteriana e desfechos obstétricos desfavoráveis em mulheres brasileiras / Correlation between bacterial vaginosis and adverse obstetric outcomes in Brazilian women

Infecções vaginais e mudanças na flora vaginal são prevalentes durante a gravidez e têm sido associadas com desfechos obstétricos adversos, tais como trabalho de parto prematuro, amniorrexe prematura e baixo peso ao nascer. Objetivos: Correlacionar a presença de vaginose bacteriana (VB) com desfecho obstétrico desfavorável em mulheres brasileiras com gravidez no terceiro trimestre. Métodos: O estudo prospectivo observacional foi conduzido avaliando microbiota vaginal por bacterioscopia (a fresco e Gram) usando swab vaginal obtido de mulheres grávidas entre a 26 e a 32a semanas de gestação. As mulheres foram monitoradas até o parto, e os dados de seu seguimento e os demográficos foram coletados por meio de um questionário autoaplicável. Resultados: Foi diagnosticada VB, com base nos critérios de Amsel e de Nugent, em 77 mulheres entre as 190, demonstrando prevalência de 42.5%. VB foi significativamente associada com maior risco de parto prematuro (risk ratio [RR], 2.89; 95% intervalo de confiança [IC], 2.35­3.56) e de baixo peso ao nascer (RR, 2.17; 95%IC, 1.61­2.92). A rotura prematura das membranas não foi associada com VB. Conclusão: Foi constatada alta frequência de VB entre as mulheres brasileiras grávidas no terceiro trimestre, e a BV correlacionou-se com piores prognósticos da gravidez. O rastreio rotineiro de mulheres grávidas pode permitir um tratamento precoce e a prevenção de algumas complicações obstétricas

Vaginal infections and modifications in the vaginal flora are very prevalent during pregnancy and have been associated with adverse obstetric outcomes, such as preterm labor, preterm premature rupture of membranes and low birth weight. Objective: To evaluate the prevalence and associations of bacterial vaginosis (BV) and pregnancy outcomes among Brazilian pregnant women in the third trimester. Methods: A prospective observational study was conducted assessing vaginal microbiota on bacterioscopy (wet mount and Gram stain), using vaginal swabs obtained from pregnant women between 26 and 32 weeks' gestation. The women were monitored until delivery, and their pregnancy outcome and demographic data were collected using an interviewer-administered questionnaire. Results: BV was assessed using both Amsel's criteria and Nugent's score in 77 of 190 women, resulting in the prevalence of 42.5%. BV was significantly associated with preterm labor (risk ratio [RR], 2.89; 95% confidence interval [CI], 2.35­3.56) and low birth weight (RR, 2.17; 95%CI, 1.61­2.92). Premature rupture of membranes was not associated with BV. Conclusion: BV was found to be very frequent among Brazilian pregnant women in the third trimester and correlated to unfortunate pregnancy outcomes. Regular screening of pregnant women may allow for early treatment and prevention of some obstetric complications.

As mais frequentes queixas ginecológicas estão associadas a infecções genitais, que afetam a microbiota vaginal, ou seja, vaginites e vaginoses. A vaginose bacteriana (VB) é caracterizada por uma mudança da microbiota vaginal de bactérias aeróbias para anaeróbias. Já a candidíase vulvovaginal (CVV) é um distúrbio ocasionado pelo crescimento anormal de fungos do tipo leveduras na mucosa do trato genital feminino. Objetivo: Identificar a frequência de VB e Candida sp em exames citológicos (Papanicolaou) em uma cidade no nordeste do Brasil, conforme os meses do ano em um período de quatro anos. Métodos: Estudo de frequência da identificação de VB e Candida sp em exames de citologia oncótica do banco de dados do Laboratório Professor Eleutério em Fortaleza entre os anos de 2012 e 2015. Resultados: Os casos avaliados tinham entre 14 e 54 anos, média de 34,7 anos. Em 2012, o mês de agosto teve maior frequência de VB (62,96%), e o mês de março teve a maior frequência de Candida sp (42,35%). No ano de 2013, VB foi mais prevalente em setembro (61,98%) e Candida sp em agosto (47,26%). Já em 2014, o mês de junho teve maior frequência VB (60,47%), e setembro maior frequência de Candida sp (43,30%). Em 2015, foi abril o mês em que mais se detectou VB (60,30%) e em junho, Candida sp (41,85%). Conclusão: A frequência de VB foi maior que a de Candida sp nos quatro anos. Os meses com maior frequência de patógenos identificados foram os de junho, agosto e setembro, no entanto não houve grandes modificações entre a distribuição durante todo o ano.

The most frequent gynecological complaints are associated with genital infections, which affect the vaginal microbiota, i.e., vaginitis and vaginosis. Bacterial vaginosis (BV) is characterized by a change of the vaginal microbiota from aerobic bacteria to anaerobic bacteria. Vulvovaginal candidiasis (VVC) is a disorder caused by the abnormal growth of yeast type fungi in the mucosa of the female genital tract. Objective: To identify the frequency of BV and Candida sp in Pap (Papanicolaou) smears in a city of Northeastern Brazil, according to the months of the year for a period of four years. Methods: Study of the frequency of the identification of BV and Candida sp in the oncotic cytology tests carried out in the Professor Eleutério Laboratory database in the city of Fortaleza from 2012 to 2015. Results: The average age of the evaluated cases was 34.7 years, varying from 14 to 54 years of age. In 2012, August was the month with a higher frequency of BV (62.96%), and the month of March had the highest frequency of Candida sp (42.35%). In 2013, BV was more prevalent in September (61.98%) and Candida sp in August (47.26%). In 2014, however, the month of June showed most often BV (60.47%) and September had a higher frequency of Candida sp (43.30%). In 2015, it was April the month in which BV was most detected (60.30%), and in June, Candida sp (41.85%). Conclusion: The frequency of bacterial vaginosis was higher than that of Candida sp during four years. The months with the highest frequency of identified pathogens were June, August and September; however, there were no major changes throughout the year.

Assessment of 100% Rapid Review as an Effective Tool for Internal Quality Control in Cytopathological Services.

OBJECTIVE: The aim of this study was to evaluate the 100% rapid review (100%-RR) as an effective tool for internal quality control (IQC) in gynecological cytopathology services. STUDY DESIGN: A total of 8,677 swabs were analyzed; the negative results were submitted to 100%-RR. Divergent cases were discussed in a consensus meeting to reach a conclusion on the final diagnosis. The data were entered into SAS statistical software, and the agreement of the 100%-RR results with the final diagnosis was tested with the weighted kappa statistic. RESULTS: Of the 8,155 smears characterized as negative, 255 (3.13%) were abnormal smears, and 552 (6.77%) unsatisfactory smears were deemed negative. Regarding the results on the 8,155 smears subjected to 100%-RR when compared with the final diagnosis, there was agreement in 7,063 (86.60%) of them, and there were 1,092 (13.40%) discordant results (65.6%, unsatisfactory; 5.47%, atypical squamous cells of undetermined significance [ASC-US]). The κ index had an agreement of 0.867, with κ = 0.734 (p < 0.0001). Compared with the final diagnosis, the sensitivity of 100%-RR was 99.91% and its specificity was 99.4% for severe abnormalities. The sensitivity for high-grade squamous intraepithelial lesions was 88.2%, with a specificity of 100.00%. For abnormalities considered borderline, such as ASC-US, the sensitivity was 94.50% and the specificity was 99.5%. CONCLUSION: The 100%-RR was considered efficient when used as an IQC method.

O risco de infecções genitais em mulheres usuárias de dispositivo intrauterino / The risk of genital infections in women using intrauterine device

Dispositivos intra-uterinos (DIU) são amplamente usados como método contraceptivo e têm uma possível associação com infecções do trato genital inferior. Objetivo: Avaliar se o uso de DIU está associado com infecções do trato genital e por quais patógenos. Métodos: Revisão sistemática de estudos dos bancos de dados PubMed, Highwire-Stanford e Google Scholar usando as seguintes palavras-chave: "cytology IUD" OR "IUD AND cytology" OR "cytology" OR "cytological techniques" OR "cytological AND techniques" OR "cell biology" OR "cell AND biology". Resultados: Foram encontrados inicialmente 2817 artigos e selecionados 16, que obedeciam os critérios de inclusão. Com base nestes estudos, o microorganismo associado ao uso de DIU e principal causa de doença inflamatória pélvica é o Actinomyces spp. Há risco 14 vezes maior de presença do Actinomyces spp. em usuárias de DIU em relação a não usuárias. No entanto, parece haver uma maior depuração aparente de infecção por Papilomavírus humano (HPV) entre usuárias de DIU de cobre. Conclusão: Há uma associação entre o uso de DIU e algumas infecções genitais, tal como vaginose bacteriana; no entanto, o agente mais evidentemente associado é o Actinomyces spp. Há uma possível maior depuração de infecção por HPV entre usuárias de DIU de cobre.

Intrauterine devices (IUDs) are widely used contraceptive methods that have a possible association with lower genital tract infections. Objective: To assess whether IUD is associated with genital tract infection and which pathogens cause it. Methods: Systematic review of studies in PubMed database, Highwire-Stanford, and Google Scholar using the following keywords: "cytology IUD," OR "IUD AND cytology" OR "cytology" OR "cytological techniques," OR "cytological AND techniques," OR "cell biology," OR "cell" and "biology". Results: Sixteen out of the 2,817 initial articles were selected using the inclusion criteria. On the basis of these studies, the microorganisms that can colonize the IUD, the main acute pelvic inflammatory disease occasioner is Actinomyces spp. There is a risk 14 times greater of the presence of Actinomyces spp. in IUD users than in non-users. However, there would be a higher apparent depuration of human papillomavirus (HPV) infection among copper T users. Conclusion: There is an association between the use of IUD and some genital infections such as bacterial vaginosis; however, more evidently associated with Actinomyces spp. There is a possible higher depuration of infection by HPV among copper T users.

High Risk HPV E6/E7 Oncoprotein Expression in Women with High Grade Squamous Intraepithelial Lesion.

PURPOSE: To correlate the expression of high-risk HPV E6 mRNA with pap smear, colposcopy, and biopsy results in women with high grade squamous intraepithelial lesion (HSIL). METHODS: A cross-sectional study was performed on women referred for primary care services after cytological diagnosis of HSIL. We evaluated the expression of E6/E7 mRNA of HPV types 16,18,31,33, and 45 and correlated the results with those of Pap smear, colposcopy, and biopsy. For amplification/detection of mRNA E6 / E7 we used NucliSENSEasyQ kit to detect HPV mRNA by polymerase chain reaction with primers/probes for HPV types 16, 18, 31, 33, and 45. RESULTS: Out of 128 valid tests, the results of 30 (23.4%) tests were negative and 98 (70%) tests were positive. Only one type of HPV was detected in 87.7% of the E6/E7 mRNA positive cases. HPV16 was detected in 61.2% of the cases, followed by HPV33 (26.5%), HPV31 (17.3%), HPV18 (10%), and HPV45 (4.08%). Pap smear tests revealed that the E6/E7 test was positive in 107 (83.8%) women with atypical squamous cells - high grade (ASC-H), HSIL, or higher. The E6/E7 test was positive in 69 (57.5%) specimens presenting negative cytology results. When analyzing the association with colposcopy results, the frequency of positive E6/E7 results increased with the severity of the injury, ranging from 57.1% in women without colposcopy-detected injury to 86.5% in those with higher levels of colposcopy findings. Of the 111 women who underwent biopsy and E6/E7 testing, the E6/E7 test was positive in 84.7% of the women who presented with lesions of cervical intraepithelial neoplasia (CIN) grade 2 or higher. Finally, 41.2% of women with a negative biopsy presented a positive E6/E7 test. CONCLUSIONS: E6/E7 mRNA expression was higher in women with HSIL and CIN grade 2 or higher.
