Asociación entre el inicio de la vida sexual y las lesiones intraepiteliales / Association between age at onset of active sexual life and intraepithelial lesion

Introducción: El cáncer cervicouterino inicia con una lesión precancerosa llamada displasia, pudiendo ser de bajo grado o alto grado; uno de los factores más importantes en este sentido es la edad de inicio de la vida sexual activa (IVSA). Objetivo: Conocer si existe asociación entre la edad de inicio de la vida sexual activa y la lesión intraepitelial escamosa de alto grado (LIEAG). Material y métodos: Estudio descriptivo, retrospectivo, observacional, en 52 expedientes de mujeres de 15 a 60 años, con Papanicolaou en el HGZ MF No. 1, previa autorización del CLIS 301 y el CEI 3018, con folio R-2022-301-021. Se recolectaron los datos de expedientes que cumplieron los criterios de inclusión; se realizó un análisis estadístico con frecuencias, porcentajes para variables cualitativas nominales, con medidas de tendencia central y dispersión en variables cuantitativas, con determinación de chi2 y prueba de Kruskal-Wallis, respetándose los principios de Belmont en consideración a la Justicia y Beneficencia, los principios éticos de la Declaración de Helsinki 1964 y la Ley General de Salud en México. Resultado: Al evaluar 52 expedientes de pacientes, la edad fue de 37.81 ± 9.949 años; se encontró asociación entre el IVSA y la LIEAG, sin significación estadística, de acuerdo con la prueba de chi2, con un valor de p = 0.538 (IC 95%: 0.403-0.674), y una asociación significativa por la prueba de Kruskal-Wallis entre la LIEAG y la edad de la paciente, con un valor de p = 0.019 (IC 95%: 0.000-0.057). Conclusión: El IVSA no se correlaciona con el tipo de LIEAG.

Introduction: Cervical cancer begins with a precancerous lesion called dysplasia, which can be low grade or high grade. One of the most important factors is the age at which an active sexual life begins. Objective: To know if there is an association between the age of beginning of active sexual life (BASL) and high-grade squamous intraepithelial lesions (HGSIEL). Material and methods: Descriptive, retrospective, observational study, in 52 files of women aged 15 to 60 years with Pap smear at HGZ MF No. 1, prior authorization from CLIS 301 and CEI 3018 with folio R-2022-301-021. Data were collected from files that met the inclusion criteria, a statistical analysis was carried out with frequencies, percentages for nominal qualitative variables, with measures of central tendency and dispersion in quantitative variables, with determination of chi2 and Kruskal-Wallis, respecting the principles of Belmont in consideration of Justice and Beneficence, the ethical principles of the Declaration of Helsinki 1964, the General Health Law in México. Result: When evaluating 52 patient records, the age was 37.81 ± 9.949 years, the association of BASL and HGSIEL was found without statistical significance according to the chi2 with a p = 0.538 (95% CI, 0.403-0.674) and a significant association by Kruskal-Wallis between HGSIEL and patient age, with p = 0.019 (95% CI, 0.000-0.057). Conclusion: The beginning of an active sexual life has no association with the type of high-grade squamous intraepithelial lesions.

Cytology-based Screening for Anal Intraepithelial Neoplasia in Immunocompetent Brazilian Women with a History of High-Grade Cervical Intraepithelial Neoplasia or Cancer / Triagem citológica de neoplasia intraepitelial anal em mulheres brasileiras imunocompetentes com histórico de neoplasia intraepitelial cervical de alto grau ou câncer

Abstract Objective To determine the prevalence and possible variables associated with anal intraepithelial neoplasia and anal cancer in immunocompetent women with high-grade cervical intraepithelial neoplasia. Methods A cross-sectional study involving immunocompetent women with a histological diagnosis of high-grade cervical intraepithelial neoplasia and cervical cancer, conducted between January 2016 and September 2020. All women underwent anal cytology and answered a questionnaire on characterization and potential risk factors. Women with altered cytology were submitted to anoscopy and biopsy. Results A total of 69 women were included in the study. Of these, 7 (10.1%) had abnormal anal cytology results: (high-grade lesion, atypical squamous cells of undetermined significance, and atypical squamous cells, cannot exclude high-grade lesions: 28,5% each; low grade lesion: 14,3%). Of the anoscopies, 3 (42.8%) showed alterations. Of the 2 (28,5% of all abnormal cytology results) biopsies performed, only 1 showed low-grade anal intraepithelial neoplasia. The average number of pregnancies, vaginal deliveries, and abortions was associated with abnormal anal cytology. However, the highest mean regarding the cesarean sections was associated with normal cytology. Conclusion The prevalence of anal intraepithelial neoplasia was compatible with data from recent studies, especially those conducted in Brazil. Opportunistic screening for anal intraepithelial neoplasia in this high-risk population should be considered. Anal cytology is suitable for this purpose, due to its low cost and feasibility in public health services.

Resumo Objetivo Determinar a prevalência e as possíveis variáveis associadas à neoplasia intraepitelial anal e ao câncer anal em mulheres imunocompetentes com neoplasia intraepitelial cervical de alto grau. Métodos Estudo transversal em mulheres imunocompetentes com diagnóstico histológico de neoplasia intraepitelial cervical de alto grau e câncer cervical, feito entre janeiro de 2016 e setembro de 2020. Todas as mulheres foram submetidas a citologia anal e responderam a um questionário de caracterização e potenciais fatores de risco. Mulheres com citologia alterada foram submetidas a anuscopia e biópsia. Resultados No total, 69 mulheres foram incluídas no estudo. Destas, 7 (10,1%) tiveram resultados anormais de citologia anal (lesão de alto grau, células escamosas atípicas de significado indeterminado, e células escamosas atípicas, não se pode excluir lesões de alto grau: 28,5% cada; lesão de baixo grau: 14,3%). Das anuscopias, 3 (42,8%) demonstraram alterações. Das 2 biópsias realizadas, apenas 1 apresentou neoplasia intraepitelial anal de baixo grau. O número médio de gestações, partos vaginais e abortos estava associado à citologia anal anormal. No entanto, a maior média de partos cesáreos estava associada à citologia normal. Conclusão A prevalência de neoplasia intraepitelial anal foi compatível com dados de estudos recentes, principalmente daqueles feitos no Brasil. O rastreamento oportunista para neoplasia intraepitelial anal nesta população de alto risco deve ser considerado. A citologia anal é adequada para esse fim, devido ao seu baixo custo e viabilidade nos serviços públicos de saúde.

Comparative analysis of anal colposcopy with histology in the follow-up of patients under treatment for anal condyloma

Objectives: To compare morphological abnormalities on anal colposcopy against histology to determine anal high-grade squamous intraepithelial lesions (HSILs). Methods: This is a retrospective data assessment of HIV-negative and HIV-positive patients undergoing outpatient follow-up. The sample comprised 54 patients presenting acetowhite lesions on anal colposcopy. Acetowhite lesions were classified according to their morphology into punctation, verrucous, mosaic, ulcerated, or hypervascularized, and biopsies of these specimens were classified as anal HSIL, low-grade squamous intraepithelial lesion (LSIL), or normal. The data were analyzed using SPSS forWindows version 13.0 (SPSS Inc., Chicago, IL, USA). The results were analyzed using the nonparametric Mann-Whitney test, the Fisher exact test and the chi-squared parametric test. A 95% confidence interval (CI) was used and a level of significance <5% was adopted for all statistical tests. Results Fifty-four patients (50 males, 80% HIV+) with biopsied acetowhite lesions were assessed. There were 31 punctation lesions, 1 classified as HSIL (3.2%; 95%CI: 0- 40.0), 17 verrucous lesions, 3 HSIL (17.7%; 95%CI: 0-10.7), and 1 ulcerated, classified as HSIL (100%), and 4 mosaic and 1 atypical vessel lesion, all classified as LSIL. The results showed no association of presence of anal HSIL with positivity for HIV infection or with counts above or below 500/µl in HIV+patients. Statistical analysis was performed using the Mann-Whitney nonparametric test, the Fisher exact test, and the chi-squared parametric test. Conclusion: The comparison of morphological findings on anal colposcopy against histology revealed no morphological pattern suggesting anal HSIL. (AU)

Value of Endocervical Curettage in Detection of High-grade Cervical Squamous Intraepithelial Lesion / 肿瘤防治研究

Objective To explore the value of endocervical curettage (ECC) in the detection of high-grade cervical squamous intraepithelial lesion (HSIL). Methods We retrospectively analyzed the clinical features and colposcopical characteristics of 678 female patients with complete clinical data. Results Among 678 cases, 391 cases were confirmed by cervical biopsy only and 7 cases by ECC only (57.67% vs. 1.03%, P < 0.001). ECC checked out 287 HSIL patients (42.33%, including cervical biopsy positive and negative cases) and cervical biopsy checked out 671 HSIL cases (98.97%, including ECC positive and negative cases). There were 68 positive ECC cases in the conversion area of Type 1+Type 2 and 247 positive ECC cases in the conversion area of Type 3(33.33% vs. 52.11%, P < 0.001). The positive rates of ECC in patients≥45 years old and < 45 years old were 145 and 170, respectively (55.13% vs. 40.96%, P < 0.001). Conclusion The cervical biopsy plays a dominant role in the detection of HSIL, and ECC can only be used as a supplement to it. Female patients older than 45 years or with Type 3 transformation zone examined by colposcopy should be concerned with cervical lesions.

Analytical study of Pap smear reports over a period of 1 year in a tertiary care centre

Background: Cervical cancer is the fourth most common cancer in women. In India and other developing countries cervical cancer is the leading cause of morbidity and mortality. Cancer cervix continues to be most common genital carcinoma in India accounting for 80% of all female genital malignancies. Pre-invase lesions can spontaneously regress to normal or remain stable for long period or progress to a higher degree of dysplasia. Cancer of cervix is preventable if diagnosed at the pre-invasive stage with regular intervals of cytological screening by Papanicolaou (Pap) smears. The aim of the study is to analyse the pap reports in terms of normal findings, infections, premalignant lesions and invasive cancers.Methods: All women attending the outpatient department gynaecology at TMMC and RC Moradabad, Uttar Pradesh over a period of 1 year from august 2017-18 presented of obstetrics and with white discharge per vagina were screened for cervical cancer using pap smear. All the smears were reported as per the 2014 Bethesda system.Results: Out of 1392 Pap smear reports ASCUS was reported in 27 cases (2%), LSIL in 27 cases (2%), HSIL in 15 cases (1%), malignant cells in 15 cases (1%) and normal including the infection is reported in 1308 cases (94%).Conclusions: Early cervical epithelial changes can be identified by a Pap smear test, which is the primary screening test for detection of precancerous cervical intraepithelial neoplasia and the early stage of invasive cervical cancer.

Experience of cervical Pap smear screening in tertiary care hospital

Background: Cervical cancer is the leading cause of death in women in developing countries like India. It is preventable by regular screening by Pap smear and can be detected at pre-invasive stage. Thus, reducing the morbidity and mortality related with cervical cancers. Objective: This study aims at detecting the prevalence and current trends of various epithelial cell abnormalities (ECAs) in females attending a tertiary care hospital. Materials and Methods: This is a retrospective study conducted in a tertiary care hospital between July 2015 and May 2019. A total of 15,270 cases comprising 11,494 conventional and 3776 liquid-based cytology Pap smears were included in the study. Clinical data and history of the patients were retrieved. All cases were reported according to Bethesda system 2014. Results: Among 15,270 cases, 793 Pap smears were unsatisfactory, 14,153 Pap smears were negative for intraepithelial lesion/malignancy, and 325 cases had ECA. Conclusion: Large hospital-based studies are required for proper implementation of health services and for the selection of a feasible as well as sensitive screening test for early detection of cervical dysplasias which can be helpful in decreasing the burden of cervical cancer in our community.

Value of transformation zone type in the evaluation of random biopsy among patients without visible lesions under colposcopy / 上海交通大学学报（医学版）

Objective: To explore the value of cervical transformation zone (TZ) type in assessing whether a random biopsy should be used to diagnose high-grade squamous intraepithelial lesion (HSIL) among patients without visible lesions under colposcopy. Methods: A total of 517 patients who underwent colposcopy (without visible lesions) due to high risk subtype infection of human papillomavirus (HPV) or thinprep cytologic test (TCT) abnormality were enrolled. TZ types were identified, random biopsies were performed, and the value of TZ type, Ⅱand III in the diagnosis of HSIL was evaluated. Results: There were 517 cases without visible lesions under colposcopy. Three hundred and ninety-six of them were TZ type III, and the detection rate of HSIL was 3.8% (15/396) by random biopsy, while one hundred and twenty one of them were TZ type and Ⅱ, and the detection rate of HSIL was 8.3% (10/121). Compared with the TZ type III, the detection rate of HSIL in the TZ type and Ⅱ was significantly increased (P=0.000). Logistic regression showed that TCT abnormality, TZ type and Ⅱ were the risk factors for HSIL detection in patients without visible lesions under colposcopy. Conclusion: Random multipoint biopsy can significantly increase detection rate of cervical HSIL when no visible lesion is visualized under colposcopy, particularly in women with abnormal TCT results or TZ type and Ⅱ.

Characteristics and significance of hr-HPV distribution of HSIL and cervical cancer in Hainan / 公共卫生与预防医学

Objective To explore the characteristics and significance of human papillomavirus (HPV) and high-risk HPV infection in cervical high-grade squamous intraepithelial lesions (HSIL) and cervical cancer (CC) in Hainan, and to provide a reference for the prevention of HPV infection and cervical cancer screening. Methods From May 2017 to December 2019, 379 gynecological inpatients in our hospital were selected (as case group), including 220 cases in the HSIL group and 159 cases in the CC group. A total of 182 healthy females undergoing physical examination in the same period of time were selected as a control group. Using PCR technology and DNA reverse dot hybridization technology, the patients were tested for HPV-DNA subtypes which were divided into 13 high-risk types and 10 low-risk types according to HPV genotypes. The relationship between HSIL and CC of patients and high-risk HPV infection was analyzed. Results (1) The HPV infection rate of HSIL and CC patients in the case group (85.75%) was significantly higher than that in the control group (26.92%) (P50-year-old group were significantly higher than those in other age groups. (4) In both the case group and the control group, single subtype infection was higher than multiple infection (P<0.001). Conclusion HSIL and CC patients in this area are mainly infected with single subtype and high-risk HPV. The infection exhibited certain differences in different ages.

Clinicopathological Pattern of Cervical Papanicolaou (PAP) Smears: A hospital based experience

Background and Objectives: Cervical cancer is very common type of cancer in women globally. The objective of this study was to compare the cytopathological findings of the cervical pap smears using the revised 2001 Bethesda system and to compare the cytopathological findings with the clinical features.Material and Methods: A total of 1016 pap smear sent to the Department of Cytopathology at Peoples Dental college general hospital (PDCH), Kathmandu over a period of three years were studied. Relevant history and clinical findings were retrieved for the study. The age, caste, location, gravida of the patient, the nature of complaint of patient to the doctor along with the per speculum findings, per vaginal examination findings of the patient and their relation to the cytopathological findings of pap smears were evaluated.Results: No significant relationship was observed between the (30-39 years) aged women and the available outcome of pap smear (p=0.404). Most of the females were Brahmin and Newars. The statistical analysis showed no significant relationship (p>0.05) between the ethnicity and pap smear result. The number of asymptomatic women in this study was found 22.9%. This study found 20.37% of intraepithelial lesion or malignancy. Trichomonas vaginalis and bacterial vaginosis combinely contributed to 0.7% of the total cases in this study. Three smear cases were detected having malignant epithelial cell which were diagnosed with adenocarcinoma, squamous cell carcinoma.Conclusion: In this study cervical pap smear was able to differentiate inflammatory, benign precursors and malignant cases. So, it is desirable to conduct routine Pap smear screening in women of all reproductive age regardless of race, ethnic background and socioeconomic status.

Therapeutic assessment of vulvar squamous intraepithelial lesions with CO2 laser vaporization in immunosuppressed patients / Avaliação terapêutica das lesões intraepiteliais escamosas da vulva com vaporização a laser CO2 em pacientes com imunossupressão

Abstract Objective A vulvar squamous intraepithelial lesion is deemed to be a preceding lesion to vulvar cancer, especially in women aged under 40 years, holders of an acquired or idiopathic immunosuppression. Several treatments have been used to treat these lesions. One of the aesthetically acceptable therapeutic methods is the CO2 laser vaporization. Methods In a transversal study, 46 records of immunosuppressed women bearing a vulvar low grade and/or high grade squamous intraepithelial lesion were selected out of the retrospective analysis, computing age, date of record, date of vulvar lesion treatment with CO2 laser, the time elapsed between the first and the last visit (in months), the number of visits, the presence or absence of condylomatous lesions in other female lower genital tract sites and whether or not recurrences and persistence of intraepithelial lesions have been noticed during the follow-up. Results Patients bearing vulvar high-grade squamous intraepithelial lesion and immunosuppressed (serumpositive forhumanimmunodeficiency virus [HIV] or with solid organs transplantation) have shown a higher level of persistence of lesions and a higher chance of having other areas of the female lower genital tract involved. Conclusion While the CO2 laser vaporization is the most conservative method for the treatment of vulvar high-grade intraepithelial lesions, it is far frombeing the ideal method, dueto the intrinsic infection features considered. The possibility of persistence, recurrences and spontaneous limited regression indicates that a closer surveillance in the long-term treated cases should be considered, in special for immunosuppressed patients.

Resumo Objetivo A lesão intraepitelial escamosa da vulva é considerada uma lesão precursora do câncer vulvar, emespecial emmulheres com idade inferior a 40 anos, portadoras de imunossupressão adquirida ou idiopática. Vários tratamentos têm sido utilizados para tratar esse tipo de lesão. Um dos métodos terapêuticos esteticamente aceitáveis é a vaporização a laser CO2. Métodos Em um estudo transversal, foram selecionados da análise retrospectiva de prontuários arquivados no setor de patologia do trato genital inferior 46 prontuários de mulheres comimunossupressão e portadoras de lesão intraepitelial escamosa de baixo grau e/ou alto grau computando-se: idade, data de registro, data do tratamento da lesão vulvar com laser CO2, tempo entre a primeira e a última consulta (em meses), número de consultas, presença ou ausência de lesões condilomatosas em outros locais do aparelho reprodutor feminino e a ocorrência ou não de recidivas e persistência de lesões intraepiteliais durante o período de acompanhamento. Resultados Pacientes com lesão intraepitelial de alto grau vulvar e imunocomprometidas (soropositivas para HIV ou com transplante de órgãos sólidos) mostraram maior índice de persistência das lesões e maior chance de ter outras áreas do órgão genital feminino comprometidas. Conclusão Embora a vaporização a laser CO2 seja o método mais conservador para o tratamento das lesões intraepiteliais vulvares de alto grau, está longe de ser o método ideal pelas características intrínsecas da afecção em foco. A possibilidade de persistência, recidivas e regressão espontânea limitada recomenda maior vigilância para os casos tratados a longo prazo, em especial para as pacientes com imunossupressão.

Analysis of the influencing factors for overtreatment in patients with high-grade squamous intraepithelial lesion on primary cervical cytology diagnosis / 中国综合临床

Objective To explore the influencing factors for overtreatment in patients with high-grade squamous intraepithelial lesion(HSIL)on primary cervical cytology diagnosis.Methods Two hundred and thirty-nine patients with initially diagnosed HSIL on cervical cytology and received cervical conization from January 2012 and December 2016 were selected in this study.Overtreatment was defined as he highest level of pathologic diagnosis which was less than or equal to the low-grade squamous intraepithelial lesion(LSIL).The relevance of patients' age,menstrual status,colposcopy finding,the level of high-risk-HPV-DNA and treatment protocol to overtreatment were investigated.Results The most serious pathological diagnosis confirmed that no CIN,LSIL,HSIL,adenocarcinoma in situ(AIS)and squamous carcinoma of cervix(SCC)were detected,with 3.8%(9/239),5.6%(14/239),87.9%(210/239),0.4%(1/239),2.1%(5/239)respectively.The overall overtreatment rate was 9.6%(23/239).The level of high-risk-HPV-DNA and colposcopic findings were significantly related to overtreatment, and colposcopic finding with LSIL was the risk factor for HSIL overtreatment(OR= 8.786,95%CI= 1.671-17.311,P= 0.015),while HPV-DNA≥1000 ng/L was the protective factor(OR=0.201,95%CI=0.043-0.951,P=0.041).Conclusion The level of high-risk-HPV-DNA and the colposcopic finding are the influencing factors for overtreatment in patients with HSIL on primary cervical cytology diagnosis.

Risk factors for unrecognized invasive carcinoma in patients with vulvar high-grade squamous intraepithelial lesion at vulvoscopy-directed biopsy / 부인종양

OBJECTIVE: To evaluate the prevalence and risk factors for unrecognized invasive carcinoma in a series of patients undergoing surgical excision after an office biopsy of vulvar high-grade squamous intraepithelial lesion (VHSIL). METHODS: Two hundred and sixteen consecutive patients treated in a tertiary-level referral center for vulvar disease in north-western Italy were recruited. Patients' records were reviewed by trained personnel. Factors showing a statistically significant (p<0.05) association with detection of stromal invasion at excisional surgery in univariate analysis were further examined in a backward stepwise multiple logistic regression model. RESULTS: The median patient age was 50 years (range, 19–88). More than 25% patients with VHSIL at biopsy had associated cervical/vaginal intraepithelial neoplasia, and more than 35% had a multifocal lesion. Invasive carcinoma was detected in surgical specimens from 24 patients (11%). The depth of stromal invasion varied between 0.1 mm and 3.0 mm with a median of 0.5 mm. In multivariate analysis, the risk of invasive carcinoma detection was greater for patients in the highest tertile of age (p=0.008), for patients with a lesion ≥20 mm in size (p=0.013) and with clitoral involvement (p<0.001), and for patients presenting with a nodular lesion (p=0.078). CONCLUSION: Our study suggests that patient age, lesion size, clitoral involvement and nodular appearance in patients with VHSIL at vulvoscopy-directed biopsy are independently associated with the risk of unrecognized invasive carcinoma.

The role of HPV type 16 E6 variant in persistent infection and recurrence of cervical HSILs after conization / 实用医学杂志

Objective To explore the role of humall papillomavims (HPV) type 16 E6 variants in the persistent infection and recurrence of the cervical high-grade squamous intraepithelial lesion (HSIL) after conization. Motheds During May to June 2012, 100 HSIL patients with HPV16 positive but negative at the margin after Loop electrosurgical excision procedure (LEEP) were selected from Shanghai People′s Hospital of Pudong District. The gene sequencing was done to the E6. The patients were followed up for 2 years. The E6 gene sequencing was done again to detect the HPV16 variants among those with persistent infections and recurrence. Results Among the 100 cases, E6 variants were detected, 81% of them HPV E6 variants Asian prototype, 14% European variant; 2% European prototype (EP) and 3% African variant 1. LEEP for Asian prototype was susceptible to the clearance of HPV16 (P < 0.001). The European variants of T350G, and A442C were correlated with persistent infection and recurrence (P < 0.001). Conclusion The HPV16 variant is closely related to the HSIL incidence. HSIL caused by HPV16 in Pudong New Area of Shanghai belong to the Asian type variant. The European variants of E6 , T350G/A442C were likely related to the recurrence of HPV16.

Cervical cancer biopsy reporting: A review.

The terminology for reporting human papillomavirus-associated squamous lesions in the cervix, both in tissue samples and cytology specimens, has suffered from many changes throughout the last years creating confusion in interpreting cervical biopsy and cytology reports by clinicians. This review presents a summary and discussion of the current terminology for reporting results of cervical biopsies and cytology with emphasis in the lower anogenital squamous terminology consensus recommendations for tissue specimens and the 2001 Bethesda Workshop for reporting cytology results. Microscopic features of cervical lesions in tissue samples and cytology specimens are presented. Biomarkers, including p16 and Ki-67, are discussed and how they can help the pathologist when dealing with difficult cases.

Clinical significance of low-grade squamous intraepithelial lesion, cannot exclude high-grade squamous intraepithelial lesion as a squamous abnormality category in cervical cytopathology / 肿瘤

Objective: To examine the histological outcomes and the predictive value of clinical risks in women with liquid-based Papanicolaou tests (PTs) interpreted as "low-grade squamous intraepithelial lesion, cannot exclude high-grade squamous intraepithelial lesion" (LSIL-H) in comparison with the 2001 Bethesda System (TBS 2001) cytologic categories of low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), and atypical squamous cells, cannot rule out a high grade lesion (ASC-H). Methods: The PTs which diagnosed as squamous cell abnormalities, including atypical squamous cells of undetermined significance (ASC-US), LSIL, ASC-H and HSIL, were reviewed by two pathologists who were blinded to the histology results. The diagnose of histology was used as gold standard, and the prevalence of high-risk human papillomavirus (HR-HPV) was examined. Results: Of 49 000 PTs, 88 (0.17%) were rediagnosed as LSIL-H. Before rediagnosed as LSIL-H, these 88 cases were diagnosed as ASC-US (19.32%, 17/88), LSIL (43.18%, 38/88), ASC-H (34.09%, 30/88) and HSIL (3.41%, 3/88). Women who diagnosed as LSIL-H had a higher incidence of cervical intraepithelial neoplasia 2 (CIN-2) /-3 or more severe lesion (CIN-3+) than that in women who diagnosed as LSIL ( P<0.01), but the incidences in these two groups were both lower than that in women who diagnosed as HSIL ( P<0.01). The difference of CIN-2/-3 incidence between LSIL-H and ASC-H was not significant. Conclusion: The similarity of histologic follow-up results between LSIL-H and ASC-H suggested that the similar management decisions should be made for women who were diagnosed as LSIL-H or ASC-H.

Comparar la prevalencia de lesiones intraepiteliales escamosas y de infecciones en la citología cervical, en dos grupos de mujeres: las trabajadoras sexuales y las usuarias del servicio de planificación familiar. Se evaluaron 1 648 informes de citología, 934 de las usuarias y 714 de trabajadoras sexuales. Unidad Sanitaria de Los Teques. En las trabajadoras sexuales las lesiones intraepiteliales escamosas de bajo grado y de alto grado se presentaron en el 0,98 por ciento y 0,60 por ciento de la población, mientras que en las usuarias fue de 0,1 por ciento de lesiones intraepiteliales escamosas de bajo grado y no se encontraron de alto grado. En las trabajadoras sexuales la prevalencia de Gardnerella vaginalis, Candida, Trichomonas vaginalis y virus de papiloma humano fue de 51,0 por ciento; 5,0 por ciento; 5,6 por ciento; 2,2 por ciento respectivamente, mientras que para las usuarias fue de 35,9 por ciento; 8,6 por ciento; 3,3 por ciento y 0,5 por ciento. Las trabajadoras sexuales presentan una desigualdad relativa mayor de sufrir infecciones de transmisión sexual con respecto las usuarias del servicio de planificación familiar.

To compare the prevalence of squamous intraepithelial lesions and infections in Pap smears, in two groups of women: the sexual workers and the women users of the family planning service. We evaluated 1 648 Pap smear reports: 714 sexual workers and 934 from users of family planning service. Setting: Unidad Sanitaria de Los Teques. In sexual workers the low grade and high grade squamous intraepithelial lesions were present in 0.98 percent and 0.60 percent of the population, while in the users there was 0.1 percent of low grade squamous intraepithelial lesions and no high grade squamous intraepithelial lesions were found. In the sexual workers the prevalence of Gardnerella vaginalis, Candida, Trichomonas vaginalis and human papilloma virus was 51.0 percent; 5.0 percent; 5.6 percent and 2.2 percent respectively, while in the users it was 35.9 percent; 8.6 percent; 3.3 percent and 0.5 percent. The sex workers present a higher odd ratio to suffer infection transmitted diseases than women users the family planning service.

Qualification of Atypical Squamous Cells of Undetermined Significance - "ASCUS, R/O HSIL": Cytologic Features and Histologic Correlation / 대한세포병리학회지

Cytologic and histopathologic features and human papillomavirus (HPV) DNA detection associated with 101 cervicovaginal smears which are classified as 'atypical squamous cells of undetermined significance, rule out high grade squamous intraepithelial lesion(ASCUS, R/O HSIL)' were reviewed and compared to 89 smears of 'ASCUS, not otherwise specified(NOS)' . Cytologic fieatures of ASCUS, R/O HSIL included atypical single small cells(36.6%), hyperchromatic tissue fragments(35.6%), atypical metaplastic cells(18.8%), endometrial cell-like clusters(5.9%), and atypical parakeratotic cells(3.0%). A final diagnosis of HSIL on biopsy was assigned to 47(54.0%) of 87 women with ASCUS, R/O HSIL and to 13(14.6%) of 89 women with ASCUS, NOS ( p=0.000). There was no difference in HPV DNA detection rate between ASCUS, R/O HSIL and ASCUS, NOS smears. These data suggest that subclassification of ASCUS is helpful to manage patients because ASCUS, R/O HSIL is more often associated with an underlying HSIL on biopsy. Therefore, women with ASCUS, rule out HSIL should be actively managed with colposcopic examination.

Chromosomal Abnormality of Spontaneous Abortus in Relation to Transvaginal Ultrasonographic Finding / 대한산부인과학회잡지

OBJECTIVE: To determine the clinical value of human papillomavirus deoxyribonucleic acid(HPV DNA) testing by polymerase chain reaction(PCR), specifically to examine whether HPV testing could identify the women with Pap smears read as mostly atypical squamous cells of undetermined significance(ASCUS) or more. METHODS: HPV DNA testing by PCR for 3 high-risk cancer associated genotypes(HPV 16, 18, 33), repeat Pap smears and colposcopically directed punch biopsies were performed concurrently on 169 women referred for cervical cancer screening test with a previous Pap smear read as ASCUS or more. RESULTS: HPV DNA testing positivity was significantly associated with abnormal cytology and high-grade squamous intraepithelial lesion(HSIL) and squamous cell carcinoma(SCC) in histology(P=0.034). The sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV) of Pap smear and HPV testing for identifying 38 cases of histologically confirmed HSIL and carcinoma by different triage protocols(HPV positive or HSIL or SCC) among 169 women were 65.8%(25/38), 85.5%(112/131), 56.8%(25/44) and 89.6%(112/125), respectively. Also sensitivity, specificity, PPV and NPV were varied by ages and more higher in older. CONCLUSION: HPV DNA testing by PCR appears to offer an effective means by which women whose cervical Pap smears have been read as ASCUS or more could be triaged for colposcopically directed biopsy. The sensitivity for HSIL could be maintained in high and specificity markedly improved by HPV genotypes 16, 18, 33.
