PURPOSES: To investigate the effect of an individualized and supervised exercise program for the pelvic floor muscles (PFM) in the postpartum period of multiparous women, and to verify the correlation between two methods used to assess PFM strength. METHODS: An open clinical trial was performed with puerperal, multiparous women aged 18 to 35 years. The sample consisted of 23 puerperal women divided into two groups: Intervention Group (IG, n=11) and Control Group (CG, n=12). The puerperal women in IG participated in an eight-week PFM exercise program, twice a week. The puerperal women in CG did not receive any recommendations regarding exercise. PFM strength was assessed using digital vaginal palpation and a perineometer. The statistical analysis was performed using the following tests: Fisher's exact, c², Student's t, Kolmogorov-Smirnov for two samples, and Pearson's correlation coefficient. Significance was defined as p<0.05. RESULTS: The participants' mean age was 24±4.5 years in IG and 25.3±4 years in CG (p=0.4). After the exercise program, a significant difference was found between the groups in both modalities of muscle strength assessment (p<0.001). The two muscle strength assessment methods showed a significant correlation in both assessments (1st assessment: r=0.889, p<0.001; 2nd assessment: r=0.925, p<0.001). CONCLUSIONS: The exercise program promoted a significant improvement in PFM strength. Good correlation was observed between digital vaginal palpation and a perineometer, which indicates that vaginal palpation can be used in clinical practice, since it is an inexpensive method that demonstrated significant correlation with an objective method, i.e. the use of a perioneometer.

PURPOSE: To assess if arylsulfatase A activity (ASA) and sulfatide (SL) concentration in the human endometrium can be predictive of the development of endometrial polyps over the years, since ASA activity reflects the endometrial sensitivity to hormones. METHODS: ASA activity and SL concentration were determined by biochemical procedures on endometrial samples collected between 1990 and 1994 in non-menopausal women. These women underwent a new endometrial sampling following the clinical indication some years after the first endometrial sampling. The histological assessment of the second endometrial specimens found four patients with normal endometrial pattern and 10 patients with one or more endometrial polyps. ASA activity/years elapsed and SL concentration/years elapsed were compared using two tailed Mann-Whitney test for unpaired data between patients with normal pattern and patients with endometrial polyps. RESULTS: Median ASA activities were 2.62 (normal pattern) versus 1.85 (endometrial polyps) nmol hydrolized substrate/min. Median activity/years elapsed is higher in patients with second endometrial sample presenting normal pattern (p=0.006) and median SL concentration/years elapsed does not differ significantly among groups, even if median SL concentration seems to be higher in patients who subsequently developed polyps (1031 µg/g of fresh tissue versus 341,5 µg/g of fresh tissue). CONCLUSIONS: ASA activity can predict the onset of endometrial polyps over the years.

PURPOSE: To evaluate the correlation between the International Consultation on Incontinence Questionnaire - Urinary Incontinence/Short Form (ICIQ-UI/SF) and Urodynamic evaluation (UE) in women with urinary incontinence (UI). METHODS: Clinical data, UE and ICIQ-UI/SF scores for 358 patients from private health service were analyzed retrospectively . The correlation between ICIQ-UI/SF and urodynamic parameters was determined by Spearman's test. A ROC curve with the sensitivity and specificity of the ICIQ-UI/SF scores was utilized to establish the value of the questionnaire that would predict an altered urodynamic parameter. The c² test or Fisher's exact test was used to calculate the p-value. The level of significance was 5% and the software used was SAS 9.2. RESULTS: Sixty-seven point three percent of the patients presented Stress UI (SUI) according to the UE (urodynamic SUI); those with SUI and Detrusor overactivity (DO) at UE represented 16.2% of the women (SUI+DO), and those with only DO at UE (DO) represented 7.3% of the women. Patients with normal UE represented 9.2% of the women. There was a significant association between ICIQ-UI/SF scores ³14 and patients with urodynamic SUI, with or without DO. Patients with Valsava Leak Point Pressure (VLPP)£90 cmH2O presented ICIQ-UI/SF³15. Spearman's test showed a weak inverse correlation between ICIQ-UI/SF score and VLPP, although it did not show any correlation with maximum cystometric capacity or with bladder volume on first desire to void. CONCLUSION: There was an association between ICIQ-UI/SF score and patients with SUI, with or without DO, but no association between the score and patients with DO alone. The lower the VLPP value, the higher the ICIQ-UI/SF score. The ICIQ-UI/SF was not able to distinguish the different types of UI in the studied population

PURPOSE: To evaluate parameters related with arterial pressure and metabolic profile in women with polycystic ovary syndrome (POS). METHODS: This monocentric study at the University Hospital Endocrinology Section included 60 women aged 18-45 years, 42 being diagnosed with POS and acting as 18 controls. All women were subjected to transvaginal ultrasound and monitored for arterial pressure for 24 h in the ambulatory (MAP). Venous blood samples were taken between 07.00 and 09.00, after 12 h fasting. Basal (BG) and fasting glucose concentrations, total cholesterol and its fractions, triglycerides and insulin (to calculate the homeostatic assay insulin-resistance, HOMA-IR) were measured. Collected data were the mean arterial blood pressure (24-h awake/sleep cycle), arterial pressure nocturnal descensus, glycemia and fasting glucose for HOMA-IR, and lipid profile. The Student's t test was used to compare homogeneous variables; the Mann-Whitney test was used to compare non-homogeneous variables; the Pearson's correlation coefficient was used to search for correlation between the variables. The c² test was used for comparison of the absence of nocturnal descensus. Significance was taken as p<0.05. RESULTS: The mean age of the patients with POS was 27.4±5.5 (18-45 years, n=42) and the body mass index (BMI) was 30.2±6.5 kg/m² (18.3-54.9). In the Control Group, the mean age was 31.4±6.1 (18-45 years) and the BMI was 27.1±6.2 kg/m² (18.3-54.9, n=18). No difference in the metabolic parameters and insulin resistance was observed between the two groups. Comparison between these parameters and MAP showed that the only parameter with a correlation was the BMI, independent of the POS diagnosis. This was not seen in nocturnal descensus, which was uncorrelated with POS and any of the other studied parameters. CONCLUSION: POS women do not show higher arterial blood pressure, glycemia, HDL-col, TG, HOMA-IR and BMI compared to non-POS women. However, POS patients showed correlation between arterial pressure and BMI, suggesting that obesity is a primary factor involved in arterial pressure changes in these patients.

PURPOSE: To compare and analyze socioeconomic aspects and the emotional experience of women with spontaneous or induced abortion and in women living in the outskirts of São Paulo. METHODS: A prospective case-control study carried out from July 2008 to March 2010, involving semi-structured interviews with women who presented a previous diagnosis of abortion and who had been admitted to two public hospitals in the outskirts of São Paulo. The study included 100 women with diagnosis of abortion and were hospitalized for curettage. Eleven women who reported induced abortion (11%) represented the case group. The control group (n=22) was selected at a 2:1 ratio according to the following procedure: for every case of induced abortion, the next two cases of spontaneous abortion at the same hospital. A semistructured interview was conducted with questions regarding emotional aspects and family, social and economic context. RESULTS: The women with induced abortion compared to the group with spontaneous abortion had lower educational level, with more frequent elementary level (82 versus 36%, p=0.04), lower income (median, R$ 1,000.00 versus R$ 1,400.00, p=0.04), lower personal income (median, R$ 200.00 versus R$ 333.00, p=0.04), higher frequency of negative feelings upon suspicion (82 versus 22%, p=0.004) and confirmation (72 versus 22%, p=0.03) of pregnancy. CONCLUSION: Among women looking for health care in hospitals in the outskirts of São Paulo, induced abortion is related to unfavorable socioeconomic conditions, which affects the emotional experiences of suspicion and confirmation of pregnancy.

PURPOSE: To create longitudinal reference intervals for pulsatility index (PI) of the umbilical (UA), middle cerebral (MCA), uterine (UtA) arteries and ductus venosus (DV) in a Brazilian cohort. METHODS: A longitudinal observational study performed from February 2010 to May 2012. Low risk pregnancies were scanned fortnightly from 18 to 40 weeks for the measurements of PI of the UA, MCA, DV and UtA. Linear mixed models were used for the elaboration of longitudinal reference intervals (5th, 50th and 95th percentiles) of these measurements. PI obtained for the placental and abdominal portions of the umbilical artery were compared by the t-test for independent samples. Two-sided p values of less than 0.05 were considered statistically significant. RESULTS: A total of 164 patients underwent 1,242 scans. There was significant decrease in PI values of all vessels studied with gestational age (GA). From the 18th to the 40th week of pregnancy, the median PI values of UA (abdominal and placental ends of the cord), MCA, DV and the mean PI of the UtA ranged from 1.19 to 0.74, 1.33 to 0.78, 1.56 to 1.39, 0.58 to 0.41, and 0.98 to 0.66, respectively. The following equations were obtained for the prediction of the medians: PI-UA=1.5602786 - (0.020623 x GA); Logarithm of the PI-MCA=0.8149111 - (0.004168 x GA) - [0.02543 x (GA - 28.7756)²]; Logarithm of the PI-DV=-0.26691- (0.015414 x GA); PI-UtA = 1.2362403 - (0.014392 x GA). There was a significant difference between the PI-UA obtained at the abdominal and placental ends of the umbilical cord (p<0.001). CONCLUSIONS: Longitudinal reference intervals for the main gestational Doppler parameters were obtained in a Brazilian cohort. These intervals could be more adequate for the follow-up of maternal-fetal hemodynamic modifications in normal and abnormal pregnancies, a fact that still requires further validation.

A dichorionic twin pregnancy with complete hydatidiform mole and coexistent fetus is a rare and challenging situation, whose pathogenesis has not been yet fully understood. We present a case of a 39-year-old woman who underwent intracytoplasmic sperm injection with two embryos transfer. The 12-week gestation ultrasound examination revealed normal fetus and placenta with features of hydatidiform mole, leading to pregnancy termination. Autopsy and histological examinations diagnosed a complete mole coexisting with a normal fetus, and the genetic analysis showed a diploid fetus with biparental genome and molar tissue with paternal diploidy. This case highlighted that complete molar pregnancies may still occur even though pregnancy is achieved after intracytoplasmic sperm injection. A review of the literature was performed by collecting data from the few similar reported cases and by commenting on the pathogenesis of this rare condition.
