PURPOSE: to evaluate ophthalmic and retinal central artery Doppler indices during the second and third trimesters of normal pregnancy and to compare the right with left eye Doppler indices of normotensive women. METHODS: a cross-sectional study which evaluated central retinal and ophthalmic artery Doppler velocimetry values of 51 normal pregnant women, in the 20th to 38th week of gestation. The following values were analyzed: pulsatility and resistance indexes (PI, RI), peak systolic and end-diastolic flow velocity (PSV, EDFV) and peak velocity ratio (PVR). The Doppler indices in the right and left eyes were studied by the median. The paired Student's t test was used to confront the right and left eye values and the Pearson linear correlation analysis was performed to study the value changes throughout the gestation, with the level of significance set at 5%. RESULTS: Doppler velocimetry indices of ophthalmic and central retinal arteries (median values) were, respectively: PI=1.83; RI=0.78; PSV=34.20; EDFV=6.80; PVR=0.48 and PI=1.34; RI=0.70; PSV=7.40; EDFV=2.10. There was no significant difference between the right and left side Doppler values. Linear correlation analysis showed no association between the arterial values and pregnancy age. CONCLUSION: the unilateral analysis of ophthalmic and central retinal artery Doppler velocimetry values can be used in systemic maternal disease. There is no significant change in ophthalmic and central retinal artery Doppler velocimetry values throughout normal pregnancy.

PURPOSE: To describe the characteristics of mothers and children and to evaluate the factors associated with discontinuation of exclusive breastfeeding. METHODS: A cross-sectional study on infants under six months of age who attended the vaccination campaign in 2008. In the sample design, vaccination units were selected by drawing lots and infants were similarly selected later at each unit systematically. A semi-structured instrument was used for data collection, containing questions about children's nutrition and socio-demographic characteristics. We used Odds Ratio and the χ² test for data analysis, accepting as the critical level p<0.05. RESULTS: The prevalence of breastfeeding for infants under 120 and 180 days of age was 89.5 and 85% respectively, and exclusive breastfeeding was 50.6 and 39.7% for infants less than 120 and 180 days of age, respectively. The factors most related to the abandonment of exclusive breastfeeding in infants under six months were maternal employment outside the home (OR=2.73; 95%CI=1.74-4.29) and use of pacifiers (OR=4.26; 95%CI=2.85-6.38). The mother being multiparous (OR=0.57; 95%CI=0.40-0.81) and receiving postpartum care in the public health care network (OR=0.55; 95%CI=0.39-0.79) represented protective factors against the practice of early cessation of breastfeeding. CONCLUSIONS: The prevalence of breastfeeding and exclusive breastfeeding in the municipality of Uberlândia is among the highest in the country and the factors most often associated with the practice of early weaning were maternal employment outside the home, offering pacifiers to the infants, receiving postpartum care in the private health sector, and primiparity.

Purpose: to determine the role of sonohysterography in the evaluation of abnormalities in the uterine cavity in patients presenting abnormal uterine bleeding, who had previously been selected by transvaginal ultrasonography. Methods: forty-eight patients presenting abnormal uterine bleeding and changes in the uterine cavity seen by transvaginal ultrasonography were selected, and they were in the menacme or postmenopause period. All patients underwent a sonohysterography, and later a hysteroscopy and/or a hysterectomy. The sonohysterographies were evaluated by two different physicians, and the diagnoses were compared. Results: the sonohysterography method showed high sensitivity and specificity for the diagnosis of benign pathologies in the uterine cavity. First, in the presence of polyps the sensitivity and specificity rates were 100 and 97%, respectively, second, in the presence of submucous myoma, they were 83 and 100%, and finally, concerning endometrial hyperplasia and normal endometrium, they were 100%. We diagnosed thirty-three cases of polyps, thirteen cases of submucous myoma, four cases of endometrial hyperplasia and three normal cases. The correlation between the diagnoses provided by the two physicians was high. Conclusions: sonohysterography is a safe and fast method which is very well tolerated by the patient, and has low levels of complications. Its high sensitivity and specificity allow this method to be used for routine diagnosis concerning benign pathologies in the uterine cavity of patients presenting abnormal uterine bleeding.

, Pre-eclampsia is a multifactorial and multisystemic disease specific to gestation. It is classically diagnosed by the presence of hypertension associated with proteinuria manifested in a previously normotensive pregnant woman after the 20th week of gestation. Pre-eclampsia is also considered in the absence of proteinuria if there is target organ damage. The present review takes a general approach focused on aspects of practical interest in the clinical and obstetric care of these women. Thus, it explores the still unknown etiology, current aspects of pathophysiology and of the diagnosis, the approach to disease prediction, its adverse outcomes and prevention. Management is based on general principles, on nonpharmacological and on pharmacological clinical treatment of severe or nonsevere situations with emphasis on the hypertensive crisis and eclampsia. Obstetric management is based on preeclampsia without or with signs of clinical and/or laboratory deterioration, stratification of gestational age

PURPOSES: To evaluate the hemodynamic patterns of the ophthalmic artery by Doppler analysis in women with gestational diabetes mellitus (GDM), comparing them to normal pregnant women. METHODS: A prospective case-control study that analyzed the ophthalmic artery Doppler indices in two groups: one consisting of 40 women diagnosed with GDM and the other of 40 normal pregnant women. Included were pregnant women with GDM criteria of the American Diabetes Association - 2012, with 27 weeks of pregnancy to term, and excluded were women with hypertension, use of vasoactive drugs on or previous diagnosis of diabetes. Doppler analysis was performed in one eye with a 10 MHz linear transducer and the Sonoace 8000 Live Medison® equipment . The following variables were analyzed: pulsatility index (PI), resistance index (RI), peak velocity ratio (PVR), peak systolic velocity (PSV) and end diastolic velocity (EDV). To analyze the normality of the samples we used the Lillefors test, and to compare means and medians we used the Student's t-test and Mann-Whitney test according to data normality, with the level of significance set at 95%. RESULTS: The median and mean values with standard deviation of the variables of the ophthalmic artery Dopplervelocimetry group GDM and normal pregnant women were: IP=1.7±0.6 and 1.6±0.4 (p=0.7); IR=0.7 and 0.7 (p=0.9); RPV=0.5±0.1 and 0.5±0.1 (p=0.1), PSV=33.6 and 31.9 cm/sec (p=0.7); VDF=6.3 and 7.9 cm/sec (p=0.4). There was no significant difference in the means and medians of these variables between the two groups of pregnant women. CONCLUSIONS: The ophthalmic artery hemodynamic patterns, analyzed by means of a Doppler technique remained unchanged in the group of pregnant women with GDM compared to the group of normal pregnant women, suggesting that the time of exposure to the disease during pregnancy was too short to cause significant vascular disorders in the central territory.

To determine whether the antral follicle count can predict the number of retrieved oocytes in patients undergoing in vitro fertilization (IVF) and to correlate it with maternal age and pregnancy rate.
This was a retrospective observational study based on a review of medical records from 193 patients who underwent assisted reproduction techniques between September 2010 and September 2012 in a Clinic for Human Reproduction. The study included women indicated for IVF who had follicle-stimulating hormone levels below 10 mIU/mL on third day of the menstrual cycle, with oocyte recipients being excluded. The patients were divided into three groups according to the number of antral follicle (up to 10 follicles, 11–22 follicles, and 23 or more follicles). To compare these three groups with the group of patients who became pregnant, patients who had not developed oocytes and had not undergone embryo transfer were also excluded. Spearman's correlation coefficient was used to measure the level of association between the numerical variables, and χ2 test was used to compare pregnancy rates with antral follicle count. To assess the likelihood of pregnancy, we used multivariate logistic regression, with the level of significance set at 5%.
The pregnancy rate of the sample was 35.6%. There was a positive significant correlation (sc) between antral follicle count and number of retrieved oocytes (sc=0.5; p<0.05) and a negative correlation between antral follicle count and age (sc= -0.5; p<0.05). There was no significant difference (p=0.16) when groups with different numbers of follicles were compared to the positive pregnancy test group; however, a cutoff of 27 antral follicles was observed in multivariate analysis, after which the probability of successful gestation tended to remain constant.
The antral follicle count decreases over the years, is a predictor of the number of retrieved oocytes and can predict the likelihood of the success of in vitro fertilization.

Purpose: to evaluate hysterosalpingo-contrast sonography as an alternative method in the study of tubal patency in a group of infertile women. Methods: this is a transversal clinic study, which analyzed hysterosalpingo-contrast sonography and compared it with hysterosalpingography, as a method for the study of tubal patency, in a group of 31 infertile patients. Hysterosalpingo-contrast sonography had a sensitivity of 93.6%, specificity of 75%, positive predictive value of 95.6%, negative predictive value of 66.7% and accuracy of 90%. The tubes were not accessible in 8.9%. The mean time to perform the examination was 12 minutes. Fourty-six percent of the patients did not report pain during the examination and 23% reported light, 19.2% moderate, and only 11.5% reported severe pain. Conclusion: hysterosalpingo-contrast sonography proved to be a safe, and tolerable method, of quick performance, with good sensitivity and specificity in the study of tubal patency in infertile women.

PURPOSE: to analyze the ophthalmic artery functioning in pregnant women with systemic lupus erythematosus (PL) without active renal disease as compared to non-pregnant women with lupus (NPL) without active renal disease, and to normal pregnant women (PN). METHODS: observational study that analyzed ophthalmic artery dopplervelocimetric variables of 20 PN, 10 PL and 17 NPL women. The variables analyzed were: pulsatility index (PI), final diastolic velocity (FDV) and velocity peak ratio (VPR). Mean and standard deviation of these indexes were calculated. For group mean comparison, analysis of variance (ANOVA) and the post-hoc Tukey test have been used, with confidence interval of 95% (p<0.05). RESULTS: the PN group showed the following means and standard deviations of ophthalmic artery parameters: PI=2,4±0,3; VPR=0,5±0,1 e FDV=5,1±2,1 cm/s. The PL and NPL groups showed the following values, respectively: PI=2,0±0,4 and 1,9±0,4; VPR=0,6±0,1 and 0,6±0,1; FDV=9,7±3,9 cm/s and 8,1±4,3 cm/s. There was not significant mean difference between the PL and NPL groups for PI, VPR or FDV. However, statistically significant mean differences were observed between PN and PL for PI, VPR and FDV, with higher values of FDV and VPR in the PL group. CONCLUSIONS: there was a reduction of ophthalmic artery vascular impedance with orbital hyperfusion in the two groups of women with lupus erythematosus as compared to normal pregnant women. These results may help to improve the understanding on pathophysiology of systemic lupus erythematosus. In addition, the present method may be applied in future studies as a complementary procedure for the differential diagnosis between pre-eclampsia and renal failure due to lupus.
