The aim of this study was to study the effects of Tribulus terrestris on sexual function in menopausal women.
This was a prospective, randomized, double-blind, placebo-controlled clinical trial that included 60 postmenopausal women with sexual dysfunction. The women were divided into two groups, placebo group and Tribulus group, and evaluated by using the Sexual Quotient-female version (SQ-F) and Female Intervention Efficacy Index (FIEI) questionnaires.
There was no significant difference between the groups in age, age at menopause, civil status, race, and religion. In the evaluation with the SQ-F questionnaire, there were significant differences between the placebo (7.6±3.2) and Tribulus (10.2±3.2) groups in the domains of desire and sexual interest (p d" 0.001), foreplay (3.3±1.5 versus 4.2±1.0) (p d" 0.01), arousal and harmonious interaction with the partner (5.7±2.1 versus 7.2±2.6) (p d" 0.01), and comfort in sexual intercourse (6.5±2.4 versus 8.0±1.9) (p d" 0.01). There was no significant difference between the placebo and Tribulus groups in the domains of orgasm and sexual satisfaction (p = 0.28). In the FIEI questionnaire, there was a significant improvement (p < 0.001) in the domains of vaginal lubrication during coitus and/or foreplay (20 versus 83.3%), sensation in the genitalia during sexual intercourse or other stimuli (16.7 versus 76.7%), sensation in the genital region (20 versus 70%), sexual intercourse and/or other sexual stimulations (13.3 versus 43.3%), and the ability to reach orgasm (20% versus 73.3%). There was no significant difference in adverse effects between the two groups.
After 90 days of treatment, at the doses used, we found Tribulus terrestris to be effective in treating sexual problems among menopausal women.

In order to increase the success rate of in vitro fertilization cycles, several studies have focused on the identification of the embryo with higher implantation potential. Despite recent advances in the reproductive medicine, based on the OMICs technology, routinely applicable methodologies are still needed. Thus, in most fertilization centers embryo selection for transfer is still based on morphological parameters evaluated under light microscopy. Several morphological parameters may be evaluated, ranging from the pronuclear to blastocyst stage. In general, despite the day of transfer, some criteria are suggested to present a predictive value for embryo viability when analyzed independently or combined. However, the subjectivity of morphological evaluation, as well as the wide diversity of embryo classification systems used by different fertilization centers shows contrasting results, making the implementation of a consensus regarding different morphological criteria and their predictive value a difficult task. The optimization of embryo selection represents a large potential to increase treatment success rates, allowing the transfer of a reduced number of embryos and inimizing the risks of multiple pregnancy.

PURPOSE: to evaluate the performance of the combined first trimester screening for chromosomal abnormalities in a group of the Brazilian population. METHODS: a retrospective study including pregnant women with single fetuses referred to a fetal medicine center to perform the first trimester screening that combines maternal age, nuchal translucency measurement and two maternal serum biochemical markers: free B-hCG and PAPP-A. To evaluate the performance of the test, the detection rate, specificity, negative and positive predicted values and false-positive rates were calculated, considering as high risk the cut-off value above 1 in 300. RESULTS: we studied 456 patients submitted to the test. Advanced maternal age above 35 years was observed in 36.2% of cases. The incidence of chromosomal abnormalities in the study population was 2.2%. Twenty-one patients (4.6%) presented a high risk (above 1:300) by the combined test. Using this cut-off level, the detection rate of the test was 70% for all chromosomal abnormalities and 83.3% for trisomy 21, for a false-positive rate of 3.1%. CONCLUSIONS: the combined first trimester screening was effective to detect chromosomal abnormalities, mainly for trisomy 21, with low false-positive rates. The combined test contributed to decreasing the indication of an invasive test if we compare to maternal age alone as a risk factor.

PURPOSE: to evaluate the impact of hysterectomy on the sexuality of women with uterine leiomyoma. METHODS: prospective study including 33 sexually active women, with ages from 35 to 50 years old, with orgasmic experience and with a fit stable partner. All the women were submitted to two instruments for the evaluation or their sexuality: Sexual Quotient - Female Version (SQF) and Sexual Satisfaction Inventory - Female Version (SSIF). Both instruments were applied by the same examiner, before and six months after the hysterectomy. RESULTS: the SQF has shown that 39.4% of the patients presented deterioration in the sexual intercourse, even though there has not been found an association between the SQF results before and after hysterectomy (χ2= 0.6; degree of freedom=12; p=0.05). The mean scores obtained after the application of the SSIF have shown significant deterioration in the following parameters: sexual satisfaction (p=0.03); expression of feminine sensuality (p=0.01); vaginismus/dyspareunia (p=0.02) and anorgasmia (p=0.04). CONCLUSIONS: it seems that hysterectomy has a negative impact on women's sexual life, with reports of decreased libido, arousal and orgasmic capacity.

PURPOSE: to evaluate the effects of tamoxifen on the expression of TGF-β and p27 proteins in polyps and adjacent endometrium of women after menopause. METHODS: prospective study with 30 post-menopausal women with diagnosis of breast cancer, taking tamoxifen (20 mg/day), presenting diagnosis of suspect endometrial polyps through transvaginal ultrasonography, and submitted to diagnostic and surgical hysterectomy to withdraw the polyps and adjacent endometrium. A immunohistochemical study has been done to verify the expression of the TGF-β and p27 proteins in the polyps and adjacent endometrium. These proteins' quantification has been done by morphometry. RESULTS: the patients' average age was 61.7 years old; their average age at the menopause onset was 49.5; and the average of using tamoxifen was 25.3 months. The average concentration of positive cells for TGF-β protein in the glandular and stroma polyp epithelium was 62.6±4.5 cells/mm². For the p27, in the glandular polyp epithelium, it was 24.2±18.6 cells/mm² and for the stroma, 19.2±15.2 cells/mm². There was no significant difference between the expression of TGF-β and p27 in the glandular epithelial form the polyps and the adjacent endometrium. The expression of proteins in the polyp and adjacent endometrium with its respective glandular and stroma epithelium showed a significant difference for the p27 protein (r=0.9, p<0.05). CONCLUSIONS: we have concluded that the TGF-β expression is not related to the effect of tamoxifen on the growing of endometrial polyps, but the absence of polyps' malignization by tamoxifen may be explained by the high expression of p27 protein in its glandular epithelium.

PURPOSE: to evaluate the sensitivity, specificity, positive and negative predictive value of double contrast barium enema (DCBE) for the diagnoses of rectum and sigmoid endometriosis. METHODS: prospective transversal study including 37 patients with suspicion of deep endometriosis. Patients were submitted to DCBE, according to the standard technique described in the literature, and then, to laparoscopy. The results of laparoscopy and the DCBE images were interpreted and compared, based on the histological evaluation. Statistical analysis was done by association (χ2 test) and agreement analyses (Kappa's test). RESULTS: patients' average age was 35.8±4.4 years old (age group from 28 to 48 years), 85.6% of them being white and 14.4%, black women. Deep endometriosis was confirmed by laparoscopy and histological exam in all the studied patients. Intestinal endometriosis was confirmed by histological exam in 27 women (72.9%) of them. DCBE demonstrated suggestive radiologic signs of intestinal infiltration by endometriosis in 24 women (64.9%) and no signs in 13 women (35.1%). The method sensitivity was 67.5%, specificity 53.8%, positive predictive value, 77.8% and negative predictive value, 70%. Among the 24 abnormal exams, 16 (43.2%) presented radiologic speculum-type image, 16 (43.2%), an image compatible with stenosis, and four (10.8%), double contour. CONCLUSIONS: the DCBE presents high sensitivity and high positive predictive value, in the diagnosis of the rectum and sigmoid endometriosis. Radiologic images speculum and stenosis-type present high sensitivity and positive predictive value for the intestinal infiltration by endometriosis.

PURPOSE: to evaluate the histological differentiation pattern in superficial peritoneum lesions and in deeply infiltrating endometriosis (DIE) in utero-sacral ligament, bowel (rectum and sigmoid colon) and rectovaginal septum. METHODS: this prospective non-randomized study included 139 patients. Of the total, 234 biopsies were obtained (179 with DIE - Deeply Group - and 55 superficial endometriosis - Superficial Group). From the 179 DIE lesions (Depply Group), 15 were obtained from rectovaginal septum, 72 from rectosigmoid nodules and 92 from utero-sacral ligament. Biopsies were classified in well-differentiated glandular pattern, undifferentiated glandular, mixed glandular differentiation and pure stromal disease, based on specific morphological classification. RESULTS: in the Depply Group (DIE), 33.5% of the biopsies showed undifferentiated glandular pattern and 46.9% mixed glandular pattern. In the Superficial Group, there was the predominance of the well-differentiated glandular pattern (41.8%). Comparing specifically the different localizations of the biopsies of DIE lesions (Deeply Group), a predominance of mixed pattern in bowel nodules (61.1%) was noted. CONCLUSIONS: it was possible to conclude that there is a predominance of well-differentiated glandular pattern in superficial endometriosis, a predominance of mixed undifferentiated in deeply pelvic endometriosis and, specifically studying endometriosis from the rectum and sigmoid colon, there was a predominance of the mixed pattern.

PURPOSE: to quantify the presence of antithyroperoxidase (anti-TPO) and antithyroglobulin (anti-TG) antibodies, and the plasmatic concentrations of thyrotropin (TSH) and free thyroxine (FT4) in normal pregnant women. METHODS: a hundred twenty-seven pregnant women, residing in São Paulo, aged from 14 to 44 years old and gestational age > 16 weeks, determined by ultrasound performed before the 20th week of pregnancy were included in a transversal study performed in the prenatal clinic of Santa Casa de Misericórdia de São Paulo, from January 2003 to September 2004. Pregnant women using medicines or with thyroidopathy history were excluded. Antithyroperoxidase and antithyroglobulin antibodies were quantified by chemiluminescence immunoassay. The immunofluorimetry technique by time-resolved was used for determining the thyrotrophin and free thyroxine. The Student's t test, with significance of 5%, was used for analyzing the results. RESULTS: the frequency of antithyroid antibodies was 12.6% (8.6% of anti-TPO antibodies, and 4.6% of anti-TG antibodies). The average of TSH concentrations was 2.13±1.0 µU/ml, and the average of T4L was 0.9±0.5 ng/dl. It was observed alteration of the thyroid function in ten pregnant women (8%). Three of them had diagnosis of hypothyroidism: one in the clinical form of the disease, with increased TSH and decreased FT4; two in the subclinical form with increased TSH and normal FT4. Five presented decreased TSH and increased FT4, consistent with clinical hyperthyroidism and two were diagnosed with subclinical hyperthyroidism, with decreased TSH concentrations only. CONCLUSIONS: the frequency of antithyroid antibodies was 12.6% in pregnant women, the antithyroperoxidase antibodies being predominant over the antithyroglobulin antibodies. It was observed some thyroid dysfunction in 8% of the cases with alterations of TSH and/or T4L.
