PURPOSE: to test effectiveness and safety of the oral administration of a new misoprostol formulation in titrated doses for the induction of delivery of a live fetus at term. METHODS: an open pilot multicenter, non-randomized clinical trial was conducted from July to December 2008. A total of 30 patients with indications for induction of labor were included. The patients had a live fetus, Bishop score <6, vertex presentation, fetal weight <4,000g estimated by ultrasonography and amniotic fluid index >5. Exclusion criteria were previous uterine scar, non-reassuring fetal heart rate tracing, multiple pregnancy, fetal growth restriction, genital hemorrhage and presence of genital tumors, ulcerations or malformations. An initial dose of 20µg/hour of the oral misoprostol solution was used in the first 6 hours, and was increased progressively to 20µg/hour every 6 hours if labor did not start, up to a maximum dose of 80µg/h in the first 24 hours, maintained for additional 24 hours if necessary. RESULTS: labor was satisfactorily induced in 96.7% of patients. The interval between the first dose and the beginning of uterine contractions was 3.8±1.8 hours. The interval between the initial dose and delivery varied from 6 to 24 hours. The frequency of vaginal delivery was 80% (24 cases). Most of the patients (60%; n=18) initiated labor with a dose of 20mg/hour. Tachysystole occurred in 13.3% of women and meconium-stained fluid was detected in 20% of cases. There were two cases of Apgar scores <7 in the first minute and no Apgar score <7 in the fifth minute. CONCLUSIONS: the oral solution of misoprostol was effective and safe for the induction of labor. However, further randomized controlled trials are needed to compare this new formulation with misoprostol administered by the vaginal route.

PURPOSE: to describe the results of laser ablation of placental vessels for the treatment of severe twin-to-twin transfusion syndrome in an university center in Brazil. METHODS: retrospective observational study of patients treated at UNICAMP from 2007 to 2009. Laser ablation of placental vessels was performed in cases of severe twin-twin transfusion syndrome (Quintero stages II, III and IV) diagnosed before 26 complete weeks of gestation. The main variables evaluated in this series were gestational age at delivery, survival (discharge from the nursery) of at least one twin and neurological damage in survivors. Logistic regression was used to investigate the influence of cervical length, gestational age and stage of the disease (before the surgery) on the occurrence of delivery/abortion and fetal death after the intervention, and the influence on severe preterm birth and survival. RESULTS: in the whole series, at least one twin survived in 63.3% of cases (19/30). Among patients who did not have delivery/abortion after surgery, the survival of at least one twin was 82.6% (19/23). In this subgroup (n=23), mean gestational age in delivery was 31.9 weeks and neurological damage was identified in one neonate (1/31; 3.2%). Cervix length influenced the occurrence of delivery/abortion after surgery (p-value=0.008). Among seven patients (7/30; 23.3%) who carried this complication, five (5/7; 71.4%) had cervix length lower than 15 mm. Among the 23 patients who did not have delivery/abortion as a result of the surgery, the highest stages of the disease (III and IV) increased the risk of delivery prior to 32 complete weeks of gestation (p-value=0.025) and decreased the chance of survival of both twins (p-value=0.026). CONCLUSIONS: the results are similar to those available in the literature. In our series, the main factors associated with poorer results were short cervix (lower than 15 mm) and the highest stages of the disease (III and IV) at the time of the treatment.

PURPOSE: to compare two screening tests for diabetes and their results to pregnancy outcomes. METHODS: in total, 279 pregnant women were submitted to two screening tests for gestational diabetes - fasting glycemia plus risk factors (FG + RF) and to the simplified glucose tolerance test (GTT50g). Screening by FG + RF consisted of the determination of fasting glycemia and anamnesis for the identification of risk factors on the occasion of the first prenatal visit. The GTT50g was performed between the 24th and the 28th week of pregnancy and consisted of the determination of plasma glycemia under fasting conditions and one hour after an oral overload with 50 g glucose. Positive and negative results were compared to pregnancy outcome. The dependent variables were: type of delivery, gestational age, weight and ponderal index at birth, Apgar indexes <7 in the 1st and 5th minutes, need for admission to the Intensive Care Unit (ICU), duration of hospitalization, and neonatal death. Data were analyzed statistically through the Students t-test, and the level of significance was set at 5%. RESULTS: only two of the perinatal variables studied were distinguished by the tests. An abnormal GTT50g was associated with a greater proportion of cesarean deliveries (58.7 versus 34.3%) and a positive FG + RF association was related to a higher rate of premature births (15.4 versus 5.4%). The other dependent variables did not differ among patients with positive and negative results of the two screening tests. CONCLUSIONS: despite the relation between prematurity and a positive FG + RF association, the increase of caesarean sections and the abnormal GTT50g, it would be a critical failure to accept these associations as definitive. Among others explanations, multiple intercurrent factors and the characteristics of the screening tests themselves should be considered.

PURPOSE: to assess a possible association between polymorphism of the progesterone receptor gene (PROGINS) and recurrent spontaneous abortion (RSA). METHODS: in this case-control study, 85 women with at least three previous spontaneous abortions without an identifiable cause (RSA Group) and 157 women with at least two previous term pregnancies without pathologies and no previous miscarriage (Control Group) were selected. An amount of 10 mL of peripheral blood was collected by venipuncture and genomic DNA was extracted by the DTAB/CTAB method, followed by the polymerase chain reaction (PCR) under specific conditions for this polymorphism and by amplification by 2% agarose gel electrophoresis. The bands were visualized with an ultraviolet light transilluminator and the gels were photographed. Differences in the PROGINS genotype and allele frequencies between groups were analyzed by the χ2 test, with the level of significance set at p<0.05. The Odds Ratio (OR) was also used, with 95% confidence intervals 95%CI. RESULTS: PROGINS genotypic frequencies were 72.3% T1T1 and 27.7% T1T2 for the RSA group and 764% T1T1, 22.3% T1T2 and 1.3% T2T2 for the control group. There were no differecnes between groups when the genotype and allele frequencies were analyzed: respectively p=0.48 (OR: 0.8) and p=0.65 (OR: 0.9). CONCLUSIONS: our results suggest that PROGINS polymorphism is not associated with RSA.

PURPOSE: to evaluate the effect of pelvic floor muscle training (PFMT) on female sexual dysfunctions. METHODS: twenty-six women with a diagnosis of sexual dysfunction (sexual desire, arousal, orgasmic disorders and/or dyspareunia) were included in a clinical trial with a before/after approach . The assessment was carried out before, during (after five sessions) and at the end of the treatment (after ten sessions) by two-digit palpation (assessment of pelvic floor muscle, PFM, strength), intravaginal electromyography (EMG) (capture of PFM contraction amplitudes) and Female Sexual Function Index (FSFI, a questionnaire for the evaluation of sexual function). The women underwent PFMT in different positions for ten sessions (once or twice a week). For statistical analysis, absolute and relative frequencies were used for clinical characteristics and PFM strength. The Friedman test was used to compare the FSFI domain scores and EMG values, the Students t-test was used to determine the association between these values and the characteristics of the women, and the Wilcoxon test for percent modification of the EMG. The Mann-Whitney test permitted us to compare these values with clinical characteristics. The Spearman correlation test was used to correlate the EMG values with mean total score. Results were considered statistically significant if p<0.05. RESULTS: a significant improvement (p<0.0001) of FSFI scores was observed at the end of treatment compared to the values observed before and in the middle of treatment. Regarding the EMG, the amplitudes of tonic and phasic contractions increased significantly during treatment (p<0.0001). Pelvic floor strength increased, which 69% of the women presenting grade 4 or 5 at the end of treatment, with a total improvement of sexual complaints. CONCLUSIONS: the PFMT improved muscle strength and electromyography contraction amplitudes, with improved sexual function, indicating that this physiotherapy approach may be successfully used for the treatment of female sexual dysfunctions.

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 compare the quality of life (QL) of women with and without chronic pelvic pain (CPP) and to investigate the factors associated with QL in women with CPP. METHODS: a cross-sectional study was conducted on 30 women with CPP and 20 women without CPP. Sociodemographic and clinical characteristics were evaluated. QL was investigated by applying the SF-36 questionnaire, which contains eight domains: functional capacity, physical aspects, pain, general health status, vitality, social aspects, emotional aspects, and mental health. These domains can be summarized into two groups: physical component summary (PCS) and mental component summary (MCS). Pain intensity was investigated by applying the visual analogue scale. Linear regression analysis was used to compare QL scores between women with and without CPP and to identify factors associated with the QL of women with CPP. RESULTS: the mean age of women with and without CPP was 35.2±7.5 and 36±9.3 years (p=0.77), respectively. Women with CPP had a lower monthly family income (p=0.04) and a higher prevalence of dysmenorrhea (87 versus 40%; p<0.01) and depression (30 versus 5%; p=0.04) compared to women without CPP. Adjusted analysis for potential confounding variables revealed that women with CPP had lower QL scores in the pain (p<0.01) and social aspects (p<0.01) domains. Depression was negatively associated with the emotional aspects domain (p=0.05) and with the MCS (p=0.03), while pain intensity was negatively related to the pain domain (p<0.01) of the QL of women with CPP. CONCLUSIONS: women with CPP presented a worse QL compared to women without CPP. Depression and pain intensity were negatively related to the QL of women with CPP. Thus, the evaluation and treatment of pain and depressive symptoms must be among the priorities that aim to improve the QL of women with CPP.
