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.

Fine-needle aspiration cytology (FNAC) is a simple method and free from complications, among great value in mastology. Its accuracy can suffer the influence of several factors, among which we can highlight the experience of the physician who performs it. With the objective of verifying the effectiveness of FNAC performed by general gynecologists, 341 patients were studied concerning the relationship between the results of FNAC and the histology of the breast lesion. We obtained sensitivity of 70.87%, specificity of 70.58%, predictive positive value of 92.40%, predictive negative value of 89.36% and accuracy of 70.67%. We concluded that FNAC is of great value in handling breast lesions and can be appropriately performed by general gynecologists. The method, however, may lead to errors of diagnosis. We do not recommend, therefore, the use of the result of FNAC as a definitive diagnosis; instead this result must be interpreted in the context of the clinical diagnosis and mammography.

PURPOSE: to assess the knowledge, attitude and practice of breast self-examination (BSE) of women from the municipality of São Luís (MA), Brazil, and associated socio-demographic variables. METHODS: prospective and cross-sectional study, with conglomerate sampling, in which 552 women from 14 census sections of São Luís were included during the period from January to September 2003. The knowledge, attitude and practice (dependent variables) were evaluated by means of analysis of the responses of the women as "adequate" or "inadequate". The main independent variables were: age, schooling, family income and marital and menopausal status. The χ2 test was used to determine the association between categorical variables and the measurement of the crude/adjusted Odds Ratio (OR) after multivariate analysis by means of logistic regression. RESULTS: although 1/3 of the studied population did not know about BSE, the group of women who were informed about it showed adequate knowledge (60.9%), practice (59.5%) and attitude (90%). The family history of breast cancer (8.9%) was not associated with better knowledge and practice. The media (63.6%) was found to be important in disseminating information about BSE. After multivariate analysis, women with a partner (OR=1.9) presented more adequate knowledge; women older than 50 years (OR=11.7) had a better attitude towards BSE; women with more than five years of schooling (OR=2) and with a partner (OR=1.7) were associated with a more correct practice of BSE. CONCLUSION: most of the patients know and practice the BSE in São Luís and their attitude towards the procedure is extremely positive. There was a great participation of the media in the dissemination of information concerning BSE.

PURPOSE: to evaluate the epidemiologic data and signs of trophoblastic hyperplasia in patients with complete hydatidiform mole (CHM) and to estimate the risk associated with the persistence of the disease. METHODS:: we evaluated 214 patients with CHM submitted to uterine evacuation between 1980 and 2001. The patients were included prospectively. All patients were followed until negative bHCG with weekly clinical evaluation and bHCG quantification. We considered persistence when the patient needed another treatment after uterine evacuation. The risk factors for persistence were evaluated through univariate and multivariate analysis, and the odds ratio (OR) was calculated for each one. RESULTS: among the epidemiologic factors, only negative Rh was significant (OR=2.28). All signs of trophoblastic hyperplasia, represented by uterine size larger than expected, sonographic uterine volume, tecaluteinic cysts, and betaHCG higher than 10(5) were associated with risk for the presistence of the disease. The presence of at least one sign of trophoblastic hyperplasia showed sensitivity of 82% and predictive positive value of 35.1% (OR=4.8). The logistic regression identified larger uterine size than expected and bHCG higher than 10(5) as risk factors for persistence of the gestational trophoblastic disease (OR=4.1 and 5.5, respectively). CONCLUSIONS: the signs of trophoblastic hyperplasia showed good sensitivity to predict persistence of the disease; however, the low predictive positive value does not allow using these criteria to change treatment. It is very important to reinforce the importance of serial betaHCG quantification in these high-risk patients.

Purpose: to introduce the use of the hemostatic pack, a tampon consisting of compresses tied to the bleeding surface and left in place for 48 to 72 h and which is one of the therapeutic alternatives to be used in this situation. Patients and Methods: we evaluated 3 cases of massive bleeding during surgery, with the exchange, on average, of 1.4 blood volumes (1.2-2.4), in terms of hemostatic effectiveness of the pack and of some patient parameters such as age and amount and type of volume infused. Results: the mean age of the patients was 57 years (51, 56 and 64). Only one had been previously irradiated. The bleeding was of venous origin, from the fossa of the obturator nerve, the iliac plexus and the presacral plexus. The volume expander most often used was 0.9% physiological saline solution, followed by blood derivatives and by Ringer lactate. Two patients were submitted to ligation of the hypogastric vein during surgery, with no improvement. The use of hemostatic synthetic material was inefficient in all three cases. In one of the patients, the use of nonabsorbable sutures to close the bleeding area led to a considerable reduction of bleeding, but did not eliminate it completely. One patient died before 24 h had elapsed, with signs and symptoms of heart failure. The other two patients developed acute renal failure and one of them developed aspirative pneumonia during surgical reexploration. Conclusion: massive bleeding is related to high morbidity and mortality. Among the emergency measures used for hemostasis, the pack seems to be the most adequate.
