To compare the diagnostic accuracy of the classic Meisels cytologic criteria and the Schneider secondary criteria relative to the hybrid capture method for diagnosing HPV infection.
This was a retrospective study performed at a public university hospital. A total of 41 patients with a cytologic diagnosis of HPV infection and 40 HPV-negative patients were selected for review of the cervical-vaginal smears seeking to classical and secondary criteria. A single pathologist reviewed the slides in search of the criteria. The classical and secondary cytologic criteria were compared with the hybrid capture for diagnosing HPV infection. Bartleti test was applied for the age analysis, and Fisher's exact test was used to compare proportions. The tests were considered significant when the probability of rejecting the null hypothesis was less than 5% (p < 0.05).
The Meisels criteria were less sensitive (34.0%) than the secondary Schneider criteria (57.5%) when compared with the hybrid capture (p < 0.0001), although the specificity of the former criteria was non-significantly higher (91.2% and 67.7%, respectively). In cases of moderate or intense inflammation, the sensitivity and specificity of the Schneider criteria were decreased, 33.3% and 50.0% respectively (p = 0.0115).
Compared with hybrid capture for diagnosis of HPV infection, the sensitivity of the secondary Schneider criteria was higher than the classical Meisels criteria.Moderate or intense inflammation reduces the sensitivity and specificity of the secondary Schneider criteria for diagnosing HPV infection using the hybrid capture as the gold standard.

PURPOSE: to compare three methods for the detection of HPV infection and to determine the prevalence of the genotypes found. METHODS: a total of 120 cervical scrape samples from patients with cervical intraepithelial neoplasia were analyzed by the conventional polymerase chain reaction using the MY09/11 and GP05+/06+ primers, and by the Nested polymerase chain reaction. The samples were subjected to DNA amplification with the GH20 and PC04 primers (β-globin) to verify DNA quality and also by polymerase chain reaction and Nested polymerase chain reaction. The amplicons were visualized in 1.2% agarose gel stained with Blue Green Loading Dye I. Positive samples also were sequenced using the automatic DNA sequencer "MegaBACE 1000". The Χ2 and Fisher tests were used for statistical analysis with the level of significance set at 5%. RESULTS: fifteen samples were eliminated from the study because they failed to amplify the β-globin gene. Of the remaining samples, 40% (42/105) were positive using primers MY09/11, 98% (103/105) using primers GP05+/06+, and 92% (97/105) using Nested-PCR. With the MY09/11 and GP05+/06+ techniques, it was possible to obtain 100% HPV-positive samples. In this study, the prevalence of the genotypes found was 57, 23, 5, 4 and 3% for HPV genotypes 16, 18, 31, 33 and 56, respectively. HPVs 67 and 83 were present in 2%, and genotypes 6, 11, 58 and candHPV85 were present in 1% each. The prevalence of the more common genotypes (HPV 16 and 18) in this study agrees with that reported worldwide (IC95%=0.4657-0.8976). CONCLUSIONS: to obtain more reliable results, it is necessary the use of more than one primer system to detect HPV infections. We believe that the three techniques studied are important and suitable for the clinical diagnosis of HPV, when they are appropriately combined.

We have analyzed 93 pregnant women with Papanicolaou smears suggesting human papillomavirus (HPV) infection (Schneider et al's criteria) with the purpose of studying the effect of maternal age, stage of pregnancy and number of pregnancies on the incidence of this infection. The control group consisted of 93pregnant women with Papanicolaou smears not suggestive of HPV infection. The results demonstrated that HPV infection is associated with pregnant women under 20 years of age, but no differences were found regarding stage and number of pregnancies.

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.

The purpose of the present study was to evaluate some epidemiological, clinical and pathological characteristics of the different grades of vulvar intraepithelial neoplasia (VIN), and its relation with the presence of human papillomavirus (HPV). The charts of 46 women with VIN, examined from 1986 through 1997, were reviewed. For statistical analysis the chi² with yates correction when appropriate, and Fisher's exact tests were used. Regarding the grade of VIN, six women presented VIN 1, six others had VIN 2 and the remaining 34 presented VIN 3. All women presented similar characteristics such as age, menstrual status and age at first sexual intercourse. Women with more than one lifetime sexual partner had a tendency to show more VIN 3 (p = 0.090). Cigarette smoking was significantly associated with the severity of the vulvar lesion (p = 0.031). HPV was significantly more frequent in women younger than 35 years of age (p = 0.005) and in women with multiple lesions (p = 0.089). Although the number of lesions were not related to the severity of VIN (p = 0.703), lesions with extensions greater than 2 cm were significantly associated with VIN 3 (p = 0.009). The treatment of choice for VIN 3 was surgery, including local resection and simple vulvectomy. Eight women relapsed, and only one had VIN 2. We concluded that among women with VIN, cigarette smoking and more than one lifetime sexual partner were associated with high-grade lesions. HPV was more frequent among patients younger than 35 years of age presenting multiple lesions. Women with VIN 3 presented lesions bigger than 2 cm and a high relapse rate, despite the type of treatment applied.

Purpose: evaluation of the risk factors [lesion grade, seropositivity for type 1 acquired immunodeficiency virus (HIV-1) and association with pregnancy ] for relapse of human papillomavirus (HPV) induced lesions of the female genital tract. Patients and Methods: seventy patients with a clinical, colposcopic and cytologic diagnosis of HPV infection were studied. Clinical follow-up lasted at least 6 months after the initial treatment, thus permitting the evaluation of the therapeutic results. Twenty-seven of these patients were pregnant and 12 were seropositive for HIV-1. The remaining 44 patients were not in the pregnancy-puerperium cycle and 14 of them were HIV-1 positive. According to cytologic criteria, the cervical lesions were classified as changes associated with HPV or grade I cervical intraepithelial neoplasia (CIN I) (low grade lesions) or CIN II/III (high grade lesions). Data were analyzed statistically by the exact Fisher test, with the level of significance set at p<0.05. The therapeutic scheme for lesions limited to the uterine cervix was cryo- or electrocautery (EC), whereas topical 5-fluorouracil was used for the diffused lesions through the vaginal wall. For the lesions in the vulvoperineal region, 80% trichloroacetic acid was used, and when they were voluminous, EC was applied. Among the pregnant women, a cryocautery was used for lesions limited to the cervix and EC for diffuse lesions. Results: among the HIV-1-negative pregnant women there was an 87.5% rate of recurrence when the lesions were in the cervix-vagina, and no recurrence when the lesions were vulvoperineal. In contrast, seropositive pregnant women presented 100% recurrence regardless of the site of the lesion. Among nonpregnant HIV negative women, 20 and 24% recurrence was observed in the cervix-vagina and in the vulvoperineal region, respectively, as opposed to 87.5 and 100% recurrence, respectively, for the same regions among HIV positive women. The lesions associated with CIN showed a higher frequency of recurrence with increasing CIN grade and a synergistic effect with the association of HIV-1 and pregnancy. Conclusions: the recurrence rate for women treated for HPV-induced lesions is high and the association with pregnancy, HIV and increased grade of the intraepithelial lesions are synergistic factors in the determination of therapeutic failure. The site of implantation of HPV-induced lesions is of prognostic significance only when the infection is not associated with HIV.

Purpose: to assess the commonest vulvovaginal complaints and vaginal discharge etiology in the Child and Teenager Gynecologic Outpatient Clinic of the University Hospital of Brasília (AGIP/HUB). Methods: we evaluated retrospectively 210 charts of patients, younger than 19 years old, who attended AGIP/HUB with vulvovaginal complaints. Results: the average age of the 210 patients was 12 ± 2.3 years, and the vaginal discharge and vulvar pruritus were the commonest complaints. Unspecific inflammatory conditions were observed in 147 (70%) of these patients and their treatment consisted of appropriate clothing, daily activities and hygienic orientation. Antibiotic treatment was necessary in 63 patients, where specific etiologic agents were found. Gardnerella, Trichomonas, HPV and syphilis were observed only in sexually active patients. They had had their first sexual intercourse when they were 14.1 ± 1.6 years old. Twenty patients also presented vulvar complaints that were easy to handle. Conclusion: Hygiene, clothing and adequate orientation for these patients and their families are fundamental to treat vulvovaginitis, almost always avoiding the use of antibiotics.

PURPOSE: to determine the prevalence of koilocytosis in penile biopsies of partners of women with HPV-induced genital lesions, and to analyze the risk factors associated with the penile viral infection. METHODS: a total of 80 partners of HPV-infected women with genital lesions were included in this transversal cohort study. The study was carried out between May 2002 and June 2003. The mean age was 34.1 years (16 to 63). No patient reported any kind of genital lesion. They answered questions regarding the presence of urethral symptoms, history of sexually transmitted diseases, number of sexual partners, use of condoms, and circumcision. The patients were submitted to peniscopy with acetic acid and toluidine blue solutions and finally to biopsy of the suspected lesions. Data were analyzed statistically by the chi2 test. RESULTS: the examination was considered negative in 24 patients (30%). All remaining 56 patients (70%) showed white lesions and toluidine blue-positive lesions. Of these, 53 were submitted to biopsy and 41 (77.3%) presented histological changes suggestive of HPV infection. CONCLUSIONS: the prevalence of the male genital infection was 51.2% and no risk factor analyzed was associated with an increased prevalence of HPV genital infection.
