RESUMO
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 (serum positive for human immunodeficiency 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 from being the ideal method, due to 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.
OBJETIVO: A lesão intraepitelial escamosa da vulva é considerada uma lesão precursora do câncer vulvar, em especial em mulheres 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 com imunossupressão 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.

ABSTRACT Objective: To evaluate the association between p53 polymorphisms and human papillomavirus (HPV) E6/E7 mRNA expression. Methods: We analyzed 175 cervical samples from women aged 16-69 years old who were tested for HPV E6/E7 mRNA expression (NucliSENS® EasyQ® HPV). The samples were divided into three groups: positive (n = 75) those with positive HPV E6/E7 mRNA expression and positive high-risk HPV Hybrid Capture (HR-HC) test; negative (n = 52) those with negative HPV E6/E7 mRNA expression and positive HR-HC; and control (n = 48) those with negative HPV E6/E7 mRNA expression and negative HR-HC. The p53 polymorphisms at codons 11, 72, and 248 were evaluated through polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: The frequency of the arginine/arginine homozygous genotype at codon 72 was significantly higher in the positive (49.3%) than in the negative (32.7%) and control groups (20.8%, p = 0.002*). The frequency of the arginine allele was also significantly higher in the positive (67.3%) than in the negative (53.8%) and control groups (38.5%, p < 0.001*). The arginine/arginine homozygous genotype was significantly associated with positive HPV E6/E7 mRNA expression (positive group) compared with negative and control groups (odds ratio: 2.633; 95% CI, 1.399-4.954, p = 0.003). The frequency of arginine/arginine homozygous genotype at codon 72 remained significantly more frequent in the positive group of women aged ≥30 years than in the other two groups. Conclusion: The presence of the p53 arginine/arginine homozygous genotype at codon 72 was significantly associated with the positive HPV E6/E7 mRNA expression.

VEGF and podoplanin (PDPN) have been identified as angiogenesis and/or lymphangiogenesis regulators and might be essential to restrict tumor growth, progression, and metastasis. In the present study, we evaluate the association between the expression of these markers and CIN grade. Immunohistochemistry was performed in 234 uterine cervical samples using conventional histologic sections or TMA with the monoclonal antibodies to VEGF (C-1 clone) and podoplanin (D2-40 clone). Positive-staining rates of VEGF in 191 CIN specimens were significantly associated with histological grade (P < 0.001). Negative and/or focal immunostaining for PDPN were more frequent in CIN 3 (P = 0.016). We found that patients with CIN 3 more frequently had strong and more diffuse staining for VEGF and diminished staining for PDPN (P = 0.018). Strong and more diffuse VEGF immunoexpressions in CIN 2 and CIN 3 were detected when compared to CIN 1. Negative and/or focal PDPN immunoexpression appear to be more frequent in CIN 3. Moderate to strong VEGF expression may be a tendency among patients with high-grade lesions and diminished PDPN expression.

Schistosoma hematobium infection is an endemic parasitic disease in Africa, which is frequently associated with urinary schistosomiasis. The parasite infection causes epithelial changes and disruption, facilitating the infection by the human papilloma virus and human immunodeficiency virus (HIV). The authors report the case of a 44-year-old African HIV-positive woman who presented an abnormal routine Pap smear. Colposcopy examination revealed dense acetowhite micropapillary epithelium covering the ectocervix, iodine-negative, an erosion area in endocervical canal, and atypical vessels. Histologic examination of the surgical specimens showed numerous calcified schistosome eggs (probably S. hematobium) and a high-grade cervical intraepithelial neoplasia. The relation between S. hematobium infection and bladder cancer is well known; however, this relationship with cervical cancer remains controversial. The symptoms of schistosomiasis of the female genital tract are rather non-specific, and are often misdiagnosed with other pelvic diseases. The familiarity of health professionals with schistosomiasis of the female genital tract is less than expected, even in endemic regions. Therefore, great awareness of this differential diagnosis in routine gynecological practice is of paramount importance.
RESUMO
OBJECTIVE: To analyze the occurrence of atypia in the cytology/histology examinations of young women under the age of 25 years and of elderly women aged over 64 years, in the Xingu Indigenous Park and to evaluate, in a subjective manner, if the age range for screening established by the Ministry of Health and the Instituto Nacional de Câncer is appropriate for this population. METHODS: The Xingu/UNIFESP Project, in partnership with the Center for Gynecological Disease Prevention, develops programs to prevent cervical cancer. The exploratory, retrospective and descriptive study of cytological and histopathological examinations of young (12-24 years) and elderly (aged 64 and over) women of the Xingu Indigenous Park, between 2005 and 2011. RESULTS: There was low occurrence of cytological atypia in the elderly female population, but there were occasional high-grade lesions in the indigenous youth. CONCLUSION: Interrupting screening at the limit age of 64 years, as established by the Ministry of Health and the Instituto Nacional de Câncer is justified. However, screening of young women should begin at an earlier age.

Objetivo Analisar a ocorrência de atipias nos exames citológicos e histológicos de jovens e idosas indígenas, e também avaliar se a faixa etária preconizada pelo Ministério da Saúde e pelo Instituto Nacional de Câncer em rastreamento do câncer de colo uterino é adequada para essa população. Métodos O Projeto Xingu/UNIFESP, em parceria com o Núcleo de Prevenção de Doenças Ginecológicas, desenvolve programas de prevenção do câncer do colo de útero. Foi realizado estudo exploratório, retrospectivo e descritivo de exames cito/histopatológicos em jovens do Parque Indígena do Xingu de 12 a 24 anos e em idosas a partir dos 64 anos, no período de 2005 a 2011. Resultados Em idosas, houve baixa ocorrência de atipias citológicas, mas nas jovens indígenas, ocorreram casos eventuais de lesão de alto grau. Conclusão Justifica respeitar o limite de 64 anos para a interrupção do rastreamento, como o estabelecido pelo Ministério da Saúde/Instituto Nacional de Câncer, mas, nas jovens, seria importante iniciar o rastreamento mais precocemente. .
