PURPOSE: to compare intra- and postoperative results of vaginal hysterectomy with those of abdominal hysterectomy in women without genital prolapse or adnexal pathology. METHODS: a randomized, open clinical trial was conducted, involving 35 patients without genital prolapse scheduled for total hysterectomy due to benign disease, at IMIP, Recife, Brazil. These patients were randomly assigned to vaginal hysterectomy (19 patients) or abdominal hysterectomy (16 patients). Main outcome measures included estimated blood loss, rate of blood transfusion, duration of surgery, postoperative pain (intensity and analgesic requirement), time in hospital, postoperative complications, recovery time and patient satisfaction. Statistical analysis was performed using chi2, exact Fisher and Mann-Whitney tests at a 5% level of significance. RESULTS: estimated blood losses were significantly lower in vaginal hysterectomy (median of 520 mL) than in abdominal hysterectomy (median 902 mL). There was no blood transfusion among patients of the vaginal hysterectomy group, in contrast to 19% of the abdominal hysterectomy group. Duration of surgery was similar (median of 120 min in both groups). Postoperative pain, as measured by visual analog scale and analgesic requirement, was lower for vaginal hysterectomy than for abdominal hysterectomy. There was no statistically significant difference regarding frequency of postoperative complications. There was one case of infection in each group and one case of thrombosis in the vaginal hysterectomy group. Postoperative hospital stay was shorter in the vaginal group. Recovery time was significantly shorter in the vaginal group (median of 35 days) versus the abdominal group (median 40 days). Overall patient satisfaction with the operation was similar in the two groups. CONCLUSIONS: patients without genital prolapse submitted to vaginal hysterectomy for treatment of benign diseases had some advantages in relation to those submitted to abdominal hysterectomy: lower intraoperative blood loss, lower postoperative pain and faster recovery time. Vaginal hysterectomy may replace abdominal hysterectomy in most patients who require hysterectomy.

PURPOSE: to evaluate three embryo scoring systems specific for 3-day embryos and to correlate them with positive in vitro fertilization outcome. METHOD: retrospective study of the In Vitro Fertilization Program of the University Hospital, Faculty of Medicine of Ribeirão Preto, University of São Paulo. A total of 137 patients submitted to the transfer of 439 embryos were evaluated. The main outcomes measured were pregnancy and implantation rates. RESULTS: a significant difference in the three scoring systems was observed between pregnant (n=53) and non-pregnant (n=84) patients (p<0.0001). In the first embryo scoring system, in which cell number alone was used, higher pregnancy (70%) and implantation rates (42%) were observed when embryos with a mean blastomere number higher than 8 were transferred. Scoring system 2, based on a total four-point score (cleavage stage, blastomere number, fragmentation and symmetry), showed increased pregnancy (52.8%) and implantation rates (31%) for scores above 2. Scoring system 3, based on cell number and morphological criteria, also showed higher pregnancy and implantation rates with increasing average scores of the transferred embryos. CONCLUSION: the three scoring systems assessed in 3-day embryos were positively correlated with pregnancy and implantation rates.

PURPOSE: to quantitatively analyze the immunoreaction of monoclonal antibody Ki-67 in the mammary epithelium adjacent to fibroadenoma of premenopausal women treated with tamoxifen, for 50 days, at doses of 5, 10 and 20 mg/day. METHODS: we studied, prospectively, the effects of tamoxifen administered for 50 days, at doses of 5, 10 e 20 mg/day, by the immunoreaction of the Ki-67 (clone Ki-S5) monoclonal antibody on mammary epithelium adjacent to fibroadenoma in premenopausal women. We studied 58 patients in a double-blind trial who were divided into four groups: Group A (n=13; placebo), Group B (n=16; 5 mg/day tamoxifen), Group C (n=14; 10 mg/day) and Group D (n=15; 20 mg/day). All patients received the medication from the first day on of the menstrual cycle and biopsy was performed on the last day of the treatment. Cells stained and not stained by the immunoreagent were counted by optical microscopy (400X) with a digital image capturing system and image analysis. RESULTS: the average percentage of stained nuclei was calculated for all groups: Group A was 2.0 with a standard error (SE) of 0.3. In Group B it was 0.7 (SE=0.2); in Group C it was 0.4 (SE=0,2) and in Group D it was 0.1 (SE=0). Statistical analysis showed significant reductions between the groups (p<0.001), and Tukey's pairwise comparison test confirmed that there was a significant increase in the immunoreaction of the monoclonal Ki-67 antibody in groups B, C and D. CONCLUSIONS: tamoxifen, administered at doses of 5, 10 and 20 mg/day for 50 days, significantly reduced the immunoreaction of monoclonal Ki-67 in the mammary epithelium of premenopausal patients and there was no significant difference between the groups that received 5, 10 and 20 mg/day tamoxifen.

PURPOSE: to evaluate the diagnostic procedures used in women with Pap smear result of atypical glandular cells. PATIENTS AND METHODS: a prospective study with 159 women with atypical glandular cells was carried out between January and December 2000. All women were submitted to a new colpocytology and to colposcopy. Directed biopsy was performed in 50 cases, endocervical curettage in 21 and conization in 75. The performance of the diagnostic procedures was described by estimating the sensitivity, specificity, predictive values and likelihood ratio, considering histological results as gold standard. RESULTS: the histological evaluation showed 51 intraepithelial squamous lesions, 29 low grade and 22 high grade. Five women presented in situ adenocarcinoma and six patients presented invasive neoplasias. Colpocytology alone showed sensitivity and specificity of 88.5 and 39%, respectively, and colposcopy alone, 74 and 42%. The association of colpocytology with colposcopy increased the sensitivity to 98.4%, with a significantly lower specificity of 10%. Endocervical curettage showed low sensitivity (25%). CONCLUSION: the presence of atypical glandular cells on colpocytology was associated with preinvasive and invasive cervical lesions in 62.2% of the cases with histological evaluation. Repeating colpocytology and performing colposcopy allowed to select the women who needed histological evaluation. Conization was an adequate procedure when examination continued to show morphologic alterations.

PURPOSE: to study frequency of the knowledge and practice of breast self-examination (BSE), characterizing some factors that may interfere in its practice. METHOD: during one month, 505 women, who were patients of the "Centro de Saúde Escola-Marco (Belém-Pará)", were interviewed, answering questions about the practice and knowledge on breast self-examination and associated factors. Statistical analysis was perfoprmed using the chi2 test. RESULTS: 96% of the women knew about BSE. Among these, 58.9% learned about it via the midia. However, the way that provided the most correct practice was medical orientation (37.5%). Only 21.8% of the women performed the examination monthly. The main reason for the low adhesion was unfamiliarity with the technique (48.2%). Women between 30 and 39 years presented the highest percentage of monthly practice (30.2%). The women (58.2%) who carried out the monthly examination had at least an incomplete high school degree. In 58.7% of the cases, the gynecologist did not stimulate the practice of the BSE. CONCLUSIONS: although BSE is known by practically all the interviewees, more than one third of them do not practice it. The main reason of the low adhesion was the unfamiliarity with the technique. Level of instruction and age of the women interfered in the practice of BSE, but presence of breast cancer cases in the family did not.

PURPOSE: to evaluate the effects of soy germ isoflavone on menopausal symptoms and blood lipids in postmenopausal women. METHODS: a prospective study was performed on 50 women, randomly divided into two groups: 25 women on soy germ isoflavones (60 mg/day, capsules) (G1) and 25 women on placebo (G2). Inclusion criteria: women with hot flushes and FSH >40 mIU/mL, non-vegetarian, non-smoker, non-Asiatic, not in use of hormone replacement therapy and without disease of the gastrointestinal tract. For six months, the menopausal Kupperman index (MKI) and hormonal and lipid profiles were assessed. For statistical analysis, ANOVA, t test and the non-parametric Kruskal-Wallis and Mann-Whitney tests were used. RESULTS: the median MKI values, initially similar in both groups, decreased in G1 at two and four months (MKI = 14 and 9, respectively), and in G2 at two months (MKI = 15) (p<0.01). At six months, isoflavone was significantly superior to placebo in reducing hot flushes (44 versus 12%, respectively). At the end of the study, in the isoflavone group, an increase in estradiol levels (from 16,8±7.3 to 18,0±6.7 ng/dL) (p<0.05) was observed, with no alteration in FSH, LH and vaginal cytology; there was also a reduction of 11.8% in LDL (from 151.5±39.2 for 133,6±26.4 mg/dL) and a HDL increase of 27.3% (from 44.0±11.3 to 56.0±11.9 mg/dL) (p<0.05). CONCLUSIONS: soy germ isoflavone induced favorable effects on menopausal symptoms and lipid profile, showing to be an interesting option for alternative therapy in postmenopausal women.

PURPOSE: to estimate the sensitivity, specificity and accuracy of patient age, ultrasound result and CA-125 marker variables for the differential diagnosis between malignant and benign ovarian tumors. In addition, to establish a risk of malignancy index (RMI) incorporating these three variables and to estimate its sensitivity, specificity and accuracy for the differential diagnosis. METHODS: one hundred patients with ovarian tumors with surgical indication were included. The age, ultrasonographic findings and CA-125 level variables were evaluated separately and later on together as the RMI. The study was performed based on the evaluation of the sensitivity, specificity and diagnostic accuracy and the use of the measurements: likelihood ratio, odds ratio, and the Student's t test, chi², and logistic regression with univariate and multivariate analysis. RESULTS: for the age variable, sensitivity, specificity and diagnostic accuracy were 58.8, 68.2 and 65.0%, respectively. For ultrasound, 88.2, 77.3 and 81.0%. For CA-125 dosage, the values were 64.7, 74.2 and 71.0%. When the three variables were put together, as the RMI, a sensitivity of 76.5%, a specificity of 87.9% and a diagnostic accuracy of 84.0% were observed. CONCLUSIONS: RMI, made up of the association of patient age, ultrasound results and CA-125 dosage variables is a valuable indicator to distinguish between malignant and benign ovarian tumor, especially in regard to its specificity.

PURPOSE: to determine the prevalence of domestic physical violence among women who delivered at a tertiary center in the Northeast of Brazil, to study the main risk factors associated with domestic violence, and to determine perinatal outcome. METHODS: a cross-sectional study was conducted, enrolling 420 women who delivered at a tertiary center in Recife (Brazil) with fetuses weighing more than 500 g. They were submitted to interviews with open and closed questions. The prevalence of domestic physical violence was determined. Statistical analysis was performed using c² and Fisher's exact tests at a 5% level of significance. The prevalence ratio was determined as measurement of relative risk of violence. Multiple logistic regression analysis was performed and the adjusted risk was calculated. RESULTS: the prevalence of domestic physical violence was 13.1% (95% CI = 10.1-16.6) and 7.4% (95% CI = 5.2-10.2) before and during pregnancy, respectively. The pattern of violence has changed during pregnancy: stopped in 43.6%, was reduced in 27.3% and increased in 11% of the victims. After multivariate analysis the variables that persisted strongly associated with violence were low female educational level, history of violence in the women´s family, partner's use of alcohol and unemployment. Perinatal outcome was studied and a significantly higher frequency of neonatal death was observed among victims of domestic violence. CONCLUSIONS: a high prevalence of domestic physical violence was observed (about 13%) in women who delivered at a tertiary center in Northeast of Brazil. The main risk factors were low educational level and previous familiar history of violence in the women's family, alcohol use by and unemployment of their partners. Neonatal mortality was increased in victims of violence.
