PURPOSE: to evaluate the clinical and epidemiological risk factors for endometrial cancer in postmenopausal women with endometrial polyps, as well as the genetic polymorphism of the progesterone receptor (PROGINS). METHODS: a case-control study was designed with 160 postmenopausal women with endometrial polyps, compared to a normal Control Group of 400 postmenopausal women. The genotyping of PROGINS polymorphism was determined by the polymerase chain reaction. Clinical and epidemiological data were compared between benign endometrial polyps and 118 of the control subjects. Variables were also compared with regard to benign and malignant endometrial polyps. RESULTS: comparison of the epidemiological variables between groups showed a significant difference for age, ethnicity, time since menopause, parity, tamoxifen use, hypertension and breast cancer, all of them more prevalent in the polyp group. After adjustment for age, statistical significance remained only for parity (OR=1.1), hypertension (OR=2.2) and breast cancer (OR=14.4). There were six cases of malignant polyps (3.7%). The frequency of bleeding was 23.4% for benign polyps and 100% for malignant polyps, with large polyps being detected in 54.6% of the benign cases and in 100 of the malignnat ones. The frequency of arterial hypertension was 54.5% for benign polyps and 83.3% for the malignant ones. The frequency of PROGINS T1/T1, T1/T2 and T2/T2 polymorphism was 79.9%, 19.5% and 0.6%, respectively, for the polyp group, and 78.8%, 20.8% and 0.5% for the Control Group. CONCLUSIONS: elderly age, hypertension, and breast cancer were significantly associated with endometrial polyps. The presence of PROGINS polymorphism was not significantly associated with endometrial polyps. The incidence of malignant polyps was low and strongly associated with bleeding, large-sized polyp and arterial hypertension.

PURPOSE: to compare the effectiveness of the Foley balloon with vaginal misoprostol for cervical ripening and labor induction. METHODS: randomized clinical trial, not blind, conducted from January 2006 to January 2008. A total of 160 pregnant women with indication for induction of labor were included and divided into two groups, 80 for Foley and 80 for vaginal misoprostol. Inclusion criteria were: gestational age of 37 weeks or more, a live single fetus with cephalic presentation and a Bishop score of four or less. We excluded patients with a uterine scar, ruptured membranes, estimated fetal weight greater than 4000 g, placenta previa, chorioamnionitis and conditions that imposed the immediate termination of pregnancy. Statistical tests employed were Mann-Whitney, χ2 test or Fisher's exact test, and p value was significant if less than 0.005. RESULTS: misoprostol triggered more frequently spontaneous delivery (50.0 versus 15.0% for Foley, p<0.001) and required less use of oxytocin (41.2 versus 76.2%), and this group presented more tachysystole (21.2 versus 5.0%). The Foley catheter caused more discomfort to the patient (28.7 versus 1.2%). There were no differences in the time required for development of the Bishop score (20.69 versus 21.36 hours), for triggering delivery (36.42 versus 29.57 hours) or in rates of cesarean delivery (51.2 versus 42.5%). There were no significant differences in perinatal performance, with similar rates of abnormal cardiotocography (20.0 versus 21.2%), presence of meconium (13.7 versus 17.5%) and need for neonatal intensive care unit (3.7 versus 6.2%). CONCLUSIONS: the use of the Foley catheter was as effective as misoprostol for cervical ripening, but less effective in triggering spontaneous labor. Our results support the recommendation of its use for cervical ripening, especially in patients with cesarean scar.

PURPOSE: to evaluate the antenatal and postnatal risk factors of neonatal death in pregnancies with absent (DZ) or reverse (DR) end-diastolic flow in the umbilical artery. METHODS: a cross-sectional retrospective study based on data from 48 medical records of singleton pregnancies with DZ or DR, and gestational age of 24 to 34 weeks, at a maternity in the Brazilian Northeast. Mean age was 27.3 (SD: 7.9) years. Twenty (41.7%) patients were primiparas. Hypertensive disorders were found in 44 (91.7%) cases. Thirty-five women (72.9%) had DZ and 13 (27.1%) had DR. Univariate analysis was firstly done (Student's t-test and Fisher's exact test) correlating the parameters with the assessed outcome (neonatal death). Variables that showed significant association were included in the logistic regression model (Wald statistics). The level of significance was set at 5%. RESULTS: The perinatal mortality rate was 64.6% (31/48). There were five stillbirths and 26 neonatal deaths. The mean gestational age at diagnosis was 27.9 (SD: 2.8) weeks. Deliveries before 24 hours after diagnosis occurred in 52.1% of the cases. Cesarean section was performed in 85.4% of the sample. The newborns weighed 975.9 g on average (SD: 457.5). Twenty-four (57.1%) presented Apgar scores below 7 in the first minute and 21.4% in the fifth minute. Gestational age at diagnosis, birth weight and Apgar of the first minute proved to be variables significantly related to neonatal death (p values were: 0.008, 0.004, and 0.020, respectively). The Odds Ratio was 6.6, 25.3 and 13.8 for neonatal death, when the diagnosis was established at the 28th week, weight was <1000 g and first minute Apgar score was <7, respectively. CONCLUSIONS: gestational age at diagnosis, birth weight and Apgar score at the first minute were factors that could predict neonatal death in pregnancies with DV or DR determined by umbilical artery Doppler velocimetry.

PURPOSE: to determine the prevalence of HPV 16, 18, 31 and 45 in cervical screening samples of women with cellular changes and/or colposcopy suggestive of persistent high grade or low grade lesion who were submitted to conization. METHODS: a total of 120 women were included in the study. Histological analysis of the cervical cones revealed 7 cases of cervicitis, 22 of CIN1, 31 of CIN2, 54 of CIN3, and 6 invasive carcinomas. The cervical screening samples were analyzed before conization for the presence of HPV-DNA by PCR using the consensus primers PGMY09/11. HPV-DNA-positive samples were tested for the presence of HPV16, 18, 31 and 45 using type-specific primers for these HPV. RESULTS: HPV-DNA was detected in 67.5% of the studied women. HPV 16 (40%) was the most prevalent type in most ilesions, followed by HPV 31 (13.3%), 45 (13.3%), and 18 (4.1%). Multiple infections occurred in 15% of the cases and infections with other HPV types were detected in 14% of the sample. CONCLUSIONS: HPV 16 and 18 infections do not always occur as a single infection, and may be associated with other HPV types on different occasions.

PURPOSE: to study the association between hypothyroidism and depression and anxiety symptoms. METHODS: a case-control study was carried out from July 2006 to March 2008 on 100 patients (50 patients with primary hypothyroidism and 50 euthyroid controls) aged 18 to 65 years. Age, race/skin color, marital status, education level, alcohol use, working status, body mass index and menopausal status were evaluated. TSH levels were determined and the Beck Depression and Beck Anxiety Scales were applied to all cases and controls. Statistical analysis was performed using the SPSS software version 14.0. The level of significance was set at p<0.05. RESULTS: there was no demographic or epidemiologic difference between groups. The concomitant presence of anxiety and depression was five times greater among cases than among controls (20.0 versus 4.0%, p=0.01). Anxiety symptoms were approximately three times more frequent among cases (40.0%) than among controls (14.0%) (p=0.003), while the prevalence of depressive symptoms was 75% higher among cases (28.0%) than among controls (16.0%), but this did not reach statistical significance (p=0.15). We found no association between TSH levels and the prevalence of anxiety or depression symptoms. CONCLUSIONS: this case-control study showed a greater probability for hypothyroid patients to develop anxiety and depression symptoms when compared to euthyroid controls. Due to the high prevalence of hypothyroidism and depression observed in clinical practice, depressive symptoms must be considered in patients with thyroid dysfunction and depressed patients should be tested for TSH.

PURPOSE: to evaluate clinical and laboratory characteristics of first-degree male relatives of patients with a confirmed diagnosis of polycystic ovary syndrome (PCOS) and to compare the findings with a control group with no family history of PCOS. METHODS: we randomly selected 28 male individuals aged 18 to 65 years who were first-degree relatives of women diagnosed with PCOS and 28 controls matched for age, waist and body mass index (BMI). RESULTS: men with 1st degree kinship with women with PCOS had higher levels of triglycerides (189.6±103.1 versus 99.4±37.1, p<0.0001), Homeostasis Model Assessment (HOMA-IR) (3.5±9.1 versus 1.0±1.0, p=0.0077) and glucose (130.1±81.7 versus 89.5±7.8, p=0.005), and lower levels of sex hormone binding globulin (SHBG) (23.8±13.8 versus 31.1±9.1, p=0.003). SHBG levels correlated independently with triglyceride levels. These individuals also had more clinical signs of hyperandrogenism. CONCLUSIONS: male individuals who are first-degree relatives of patients with PCOS have a higher degree of dyslipidemia and insulin resistance, lower levels of SHBG, and more evident clinical signs of hyperandrogenism. These findings suggest that insulin resistance may be of hereditary origin in individuals with a family history of PCOS regardless of anthropometric parameters.
