PURPOSE: to evaluate the frequency of VDR gene polymorphism Fok1 in infertile women with endometriosis and Control and its relation to the disease. METHODS: a case-control study that included 147 infertile women with endometriosis and 154 fertile women without endometriosis as Control. Fok1 polymorphism (rs10735810, T2C), which promotes a T/C exchange in exon 2 of the VDR gene, was identified by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), that involves the combination of amplification by PCR and digestion with restriction endonuclease. The χ2 test was used to compare allele and genotype frequencies between groups. All p-values were two-tailed and a p-value < 0.05 was considered statistically significant. RESULTS: the TT, TC and CC genotype frequencies of VDR Fok1 polymorphism were 44.2%, 46.9% and 8.9% in infertile women with endometriosis and 41.6%, 50% and 8.4% in the Control Group. No significant difference was found (p=0.8), even when the patients were subdivided according to the stage of endometriosis (p=0.3 for minimal and mild endometriosis and p=0.2 for moderate and severe endometriosis). Alleles T and C were present, respectively, in 67.6% and 32.3% of infertile women with endometriosis (p=0.8), in 63.5% and 36.5% of women with minimal/mild endometriosis (p=0.5), in 72.5% and 27.5% of women with moderate/severe endometriosis (p=0.2), and in 66.6% and 33.4% of the Control Group. No statistically significant difference was found among any groups and the Control. CONCLUSION: the results suggest that VDR gene polymorphism Fok1 does not confer genetic susceptibility to endometriosis-associated infertility in the Brazilian population.

OBJECTIVE: to correlate complaints of stress urinary incontinence and the results of a one-hour pad test in pre- and postmenopausal women. METHODS: cross-sectional study conducted on 60 postmenopausal volunteers divided into two groups: one consisting of 34 women with involuntary loss of urine due to stress incontinence and the other consisting of 26 women without involuntary loss of urine. A control group of 15 premenopausal women with normal menstrual cycles and no urinary complaints was also used. All women underwent clinical and laboratory analysis as well as the one-hour pad test. Patients were considered to be incontinent when sanitary pad weight post-test was more than 1 g. Data were submitted to descriptive statistics, parametric ANOVA, post-hoc Tukey test and Pearson's correlation. RESULTS: all postmenopausal women presented with stress urinary incontinence during the pad test, both those with urinary loss (4 g) and with no previous loss (3.5 g). A strong correlation was observed between urinary loss and time since menopause (r=0.8; p<0.01) and body mass index (r=0.7; p=0.01). Premenopausal women were continent during the pad test (0.4 g). CONCLUSIONS: the results of the one-hour pad test showed that all postmenopausal women exhibited stress urinary incontinence, including those without urine loss on effort. Urine loss was correlated with time since menopause and body mass index.

PURPOSE: to determine the prevalence of lymphedema and its associated factors in breast cancer patients. METHODS: Two hundred and fifty women that had undergone more than six months of breast cancer treatment and were being treated at an oncology reference hospital in Juiz de Fora, Minas Gerais, Brazil. They were interviewed and submitted to physical evaluation. Data from the patients' medical records regarding the treatment of breast cancer, the extent of axillary intervention and the tumor were analyzed. Lymphedema was diagnosed when the difference between both upper limbs was 2 cm or more by perimetry. The groups of women with and without lymphedema were compared regarding the possible risk factors, and central tendency, dispersion, and prevalence were measured, with a significance level of 95%. RESULTS: One hundred and twelve women (44.8%) presented lymphedema. A significant difference was found between the groups of women with and without lymphedema regarding the median numbers of removed lymph nodes (p=0.02); presentation of superficial lymphatic thrombosis in the arm ipsilateral to the surgery (p<0.01); local application of radiotherapy, use of chemotherapy (p<0.01 for both); removal of the cuticles of the ipsilateral hand with pliers, and weightlifting after the treatment (p<0.01 and p=0.05, respectively). CONCLUSIONS: the association between lymphedema and the mentioned factors requires an interdisciplinary approach to this condition. It is of paramount importance that health teams and patients become aware of the prevention and treatment of lymphedema, a condition often undervalued.

PURPOSE: to determine the prevalence of adverse gestational and neonatal outcomes in women with a positive screening and negative diagnosis for gestational diabetes mellitus (GDM). METHODS: a retrospective descriptive cross-sectional study was conducted from 2000 to 2009 on 409 women with positive screening for GDM. The maternal variables studied were: age, body mass index, history of cesarean section, macrosomia or diabetes mellitus in a previous pregnancy and a personal or family history of diabetes mellitus and chronic arterial hypertension. The neonatal variables studied were: polyhydramnios, gestational age at birth, prematurity, cesarean delivery, large for gestational age (LGA) newborn, macrosomia, Apgar score, neonatal respiratory distress syndrome, hypoglycemia and hyperbilirubinemia. Uni- and multivariate descriptive analyses were first performed regarding risk factors and neonatal outcome and the prevalences and respective 95% confidence intervals were determined. RESULTS: the route of delivery was cesarian section in 255 cases (62.3%), preterm birth occurred in 14.2% of cases and 19.3% of the newborns were LGA. The risk factors correlated with LGA newborns were overweight or obesity, maternal age and a history of macrosomia in a previous pregnancy. CONCLUSIONS: a high rate of LGA newborns was observed in the population with positive risk factors or altered fasting glycemia on the occasion of the first prenatal visit, even when the glycemia curve was normal, with cesarean rates above those habitually observed in populations considered to be of low risk. Pregnant women with these characteristics represent a differential group.

PURPOSE: to determine the dietary consumption of pregnant women, by assessing the intake of macronutrients and micronutrients, and to verify the maternal weight gain during pregnancy. METHODS: a retrospective study conducted from June 2002 to June 2008 with pregnant women who received nutritional counseling during prenatal care at a university hospital, grouped according to anthropometric nutritional status classified by pregestational body mass index (BMI). The dietary intake was analyzed according to the information obtained in food frequency interviews, performed at the first evaluation of pregnant women in the service of nutrition to obtain data about eating habits, and the intake of macronutrients and micronutrients was calculated. The pregnant women received nutritional counseling, and the maternal weight gain was investigated. RESULTS: a total of 187 pregnant women who received nutritional counseling were analyzed. Twenty-three (12.2%) were underweight, 84 (45.0%) normal weight, 37 (19.8%) overweight, and 43 (23.0%) obese. The underweight pregnant women had lower consumption of lipids when compared to the normal weight group (101.4 versus 137.3 g; p=0.043). The average iron intake was higher in normal weight pregnant women (14.6 mg/d) compared to the overweight (12.2 mg/d) or obese (10.9 mg/d; p<0.001) groups. The average intake of folate was higher in normal weight pregnant women compared to obese ones (336.5 µg/d versus 234.5 µg/d; p=0.002). Excessive maternal weight gain was significantly (p=0.009) more frequent in overweight (56.7%) and obese (39.5%) pregnant women compared to underweight (17.4%) and normal weight (31.0%) women. CONCLUSIONS: The maternal weight gain above recommended levels was associated with overweight and obesity. The dietary intake of pregnant women differs according to maternal anthropometric nutritional status, with a lower daily intake of iron in overweight and obese women and a lower intake of folate in obese ones, a fact that reinforces the importance of prenatal vitamin supplementation.

PURPOSE: to estimate the prevalence and risk factors associated with seropositivity for Toxoplasma gondii in pregnant women. METHODS: a cross-sectional retrospective study based on the records of women screened for toxoplasmosis by the Pregnancy Protection Program in 2008, living in Goiânia (GO). These records were connected to records from the database of the National Information System on Live Births from the State of Goiás. The process occurred in three phases, with 10,316 records being paired for analysis, among the 12,846 initial records. The following variables were evaluated in this process: woman's name, age, date of birth, estimated date of delivery, date of infant birth and household information. Anti-Toxoplasma gondii antibodies were detected with the Q-Preven Toxo IgG and IgMin tests in dried blood samples collected on filter paper. The χ2 test and χ2 test for trend were used for data analysis, and the odds ratio (OR) was used to estimate the chance of association between exposure and outcome. RESULTS: the prevalence of infection was 67.7%, with 0.7% of the samples presenting anti-Toxoplasma gondii IgM and IgG reagents. Out of these, only three did not undergo confirmatory testing in venous blood. The median interval between the screening and the new collection of venous blood was of 12.5 days, and from screening to confirmatory test and avidity it was of 20 days. The variables associated with exposure were: age 20-30 years, OR=1.6 and >31 years, OR=1.8; brown skin color, OR=1.4, and black skin color, OR=1.6; and education of 8-11 years, OR=0.7, and >12 years of education, OR=0.6. CONCLUSION: a high prevalence of infection was estimated among the studied pregnant women. The associated factors that were found found should be considered during prenatal care, along with educational activities for the prevention of infection and assessment of serological status of seronegative pregnant women.

Dunnigan-type familial partial lipodystrophy (FPLD) is an autosomal dominant disease that results from heterozygous missense mutations in LMNA, the gene that encodes nuclear lamin A/C. FPLD is characterized by a progressive disappearance of subcutaneous adipose tissue in the limbs, gluteal region, abdomen and trunk, beginning at the time of or after puberty, and excessive amount of fat in the face, chin, labia majora, and intra-abdominal region, leading to a Cushingoid appearance and increased muscularity phenotype. Affected women are particularly predisposed to insulin resistance and its complications, including features of polycystic ovary syndrome. To emphasize the importance of an early FPLD diagnosis, which is necessary to prevent serious metabolic disturbances, we report a woman diagnosed at about 50 years of age. Increased muscularity and significant labia majora fat deposit made the diagnosis possible by gynecologists.
