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.

Objetivo: analisar os fatores epidemiológicos, manifestações clínicas e forma de tratamento da infecção pelo papilomavírus. Métodos: todos os casos de condiloma acuminado em crianças e adolescentes atendidas no período de 1990 a 1995 no Ambulatório de Ginecologia Infanto-Puberal foram revisados, tendo sido coletados dados referentes a idade, manifestações clínicas, local das lesões, formas de transmissão e tratamento. Resultados: entre os 18 casos estudados, a média de idade foi de 6 anos e 11 meses (variando de 2 a 15 anos). A manifestação clínica mais comum foi a presença de verrugas (61,1%). As lesões eram localizadas na região vulvoperineal em 44,4% das pacientes, sendo que lesões perianais e vulvares foram observadas em 27,8% e 22,2% dos casos, respectivamente. Não foi possível confirmar a ocorrência de abuso sexual nem de lesões condilomatosas nos pais em 66,7% dos casos. Provável abuso sexual (não-confirmado) foi relatado em 2 casos. A terapêutica básica foi a cauterização química. Conclusões: o abuso sexual em crianças e adolescentes com condiloma acuminado deve ser investigado, apesar da existência de outras formas de transmissão, incluindo auto ou heteroinoculação. As formas de apresentação na idade jovem diferem das do adulto, sendo necessária uma terapêutica adequada a essa população.

Parpose: to analyze the epidemiologic factors, clinical manifestations and forms of treatment of infection with papiloma virus. Method: all cases of condyloma acuminatum in children and adolescents assisted in the period from 1990 to 1995 in the Service of Children and Adolescent Gynecology were revised. We present the following data: age, diagnosis, clinical manifestations, sites of the lesions, transmission modes and treatment. Results: the average age of the 18 studied cases, was 6 years and 11 months (ranging from 2 to 15 years). The most common clinical manifestation was the presence of warts (61.1%). The lesions were located in the vulvoperineal area in 44.4% of the patients, and perianal and vulvar lesions were observed respectively in 27.8% and 22,2% of the cases. It was not possible to confirm the occurrence of sexual abuse or of condyloma lesions in the parents in 66.7% of the cases. Probable sexual abuse (not confirmed) was reported in 2 cases. The basic therapy was chemical cauterization. Conclusions: sexual abuse in children and adolescents with condyloma acuminatum should be investigated in spite of the existence of other transmission ways including auto- or heteroinoculation. The presentation forms at young age differ from those in adults, and thus an appropriate therapy for this is necessary for this population.

O adenocarcinoma de células claras de colo e vagina em adolescentes é uma doença rara e na maioria das vezes associada com o uso do dietilestilbestrol (DES) durante a gestação. A queixa mais freqüente é o sangramento vaginal irregular que pode ser incorretamente interpretado como vaginite nas crianças e como alterações do eixo hipotálamo-hipófise nas adolescentes. Relatamos o caso de adenocarcinoma de células claras de endocérvice em uma menina de 7 anos de idade atendida no Ambulatório de Ginecologia da Infância e Adolescência, e chamamos a atenção para o diagnóstico de câncer genital que, embora raro nesta faixa etária, deve ser cogitado quando deparamos com sangramento genital em crianças.

Clear cell adenocarcinoma of the vagina and cervix is a rare disease associated commonly with the use of diethylstilbestrol (DES) during pregnancy. The most commom complaint is irregular vaginal bleeding, which could be confused with vaginitis in children and abnormalities in the hypothalamic-pituitary axis in adolescents. We report a case of clear cell adenocarcinoma of the endocervix in a 7-year-old child who was attended at the Children and Adolescent Gynecology Sector, and we call attention to the diagnosis of genital cancer which, in spite of its rarity at this age, must be considered in children with genital bleeding.
