Among the clinical factors for preterm birth, some confer substantial increased risk, including a history of preterm birth, multiple gestation and vaginal bleeding in the second trimester. However, these factors are present only in a minority of women who ultimately deliver preterm and thus have low sensitivity. Cervical dilatation, effacement and position as determined by manual examination have been related to an increased risk of preterm birth but also suffer from low sensitivity and positive predictive values. Cervical length measured with transvaginal ultrasound has also been related to an increased risk of preterm birth as cervical length decreases. The reported sensitivity is better than other tests, but positive predictive value is low. The principal utility of the fetal fibronectin assay lies in its negative predictive value in symptomatic women. Increased sensitivity has been reported when cervical length is used in combination with fetal fibronectin.

PURPOSE: to characterize, phenotypically, yeasts isolated from the vaginal content of 223 symptomatic (S) and asymptomatic (A) adult women with vulvovaginitis, and to determine the clinical indicators which may lead to the appearance of signs and symptoms related to the mucosa involvement by this pathology. METHODS: a questionnaire with open and closed questions on epidemiological clinical data was applied initially. Then, mycological diagnosis with sowing in Chrom Agar Candida was done, followed by micro-morphological and biochemical identification. Specific methods for the detection of the virulence factors, proteinase and phospholipase were employed. Statistical analysis was performed through χ2 and Pearson's χ2 tests. RESULTS: the most prevalent species found was Candida albicans (87%, S and 67%, A) followed by Candida glabrata (4%, S e 17% A). The number of women reporting the use of contraceptives was higher among the symptomatic, 77%. In the two groups studied, about 87% of the women presented regular menstrual cycles and 57% were married with ages between 30 to 40 years old. Concerning the sexual practices, there has been concomitance among anal, oral and vaginal habits from the patients. Only Candida albicans produced the virulence factor phospholipase in 37.5% of them. Proteinase has been detected in Candida albicans, Candida glabrata and Candida parapsilosis. This latter virulence factor was mainly associated to isolates from symptomatic patients. CONCLUSIONS: it is a fact that the vaginal mucosa can be colonized and infected by yeasts, with several Candida species present. Nevertheless, Candida albicans is the most prevalent in the vaginal mucosa of adult women. It is evident the emergence of non-albicans Candida species, some of them with intrinsic resistance to azolics, such as Candida glabrata, Candida parapsilosis, Candida tropicalis, and Candida guillermondii, which can be explained by the inadequate use of medicines and empirical treatment.

PURPOSE: to evaluate whether the presence of insulin resistance (IR) alters cardiovascular risk factors in women with polycystic ovary syndrome (POS). METHODS: transversal study where 60 POS women with ages from 18 to 35 years old, with no hormone intake, were evaluated. IR was assessed through the quantitative insulin sensitivity check index (QUICKI) and defined as QUICKI <0.33. The following variables have been compared between the groups with or without IR: anthropometric (weight, height, waist circumference, arterial blood pressure, cardiac frequency), laboratorial (homocysteine, interleucines-6, factor of tumoral-α necrosis, testosterone, fraction of free androgen, total cholesterol and fractions, triglycerides, C reactive protein, insulin, glucose), and ultrasonographical (distensibility and carotid intima-media thickness, dilation mediated by the brachial artery flux). RESULTS: Eighteen women (30%) presented IR and showed significant differences in the following anthropometric markers, as compared to the women without IR (POS with and without IR respectively): body mass index (35.56±5.69 kg/m² versus 23.90±4.88 kg/m², p<0.01), waist (108.17±11.53 versus 79.54±11.12 cm, p<0.01), systolic blood pressure (128.00±10.80 mmHg versus 114.07±8.97 mmHg, p<0.01), diastolic blood pressure (83.67±9.63 mmHg versus 77.07±7.59 mmHg, p=0.01). It has also been observed significant differences in the following laboratorial markers: triglycerides (120.00±56.53 mg/dL versus 77.79±53.46 mg/dL, p=0.01), HDL (43.06±6.30 mg/dL versus 40.45±10.82 mg/dL, p=0.01), reactive C protein (7.98±10.54 mg/L versus 2.61±3.21 mg/L, p<0.01), insulin (28.01±18.18 µU/mL versus 5.38±2.48 µU/mL, p<0.01), glucose (93.56±10.00 mg/dL versus 87.52±8.75 mg/dL, p=0.02). Additionally, two out of the three ultrasonographical markers of cardiovascular risk were also different between the groups: carotid distensibility (0.24±0.05 mmHg-1 versus 0.30±0.08 mmHg-1, p<0.01) and carotid intima-media thickness (0.52±0.08 mm versus 0.43±0.09, p<0.01). Besides, the metabolic syndrome ratio was higher in women with IR (nine cases=50% versus three cases=7.1%, p<0.01). CONCLUSIONS: POS and IR women present significant differences in several ultrasonographical, seric and anthropometric markers, which point out to higher cardiovascular risk, as compared to women without POS and IR. In face of that, the systematic IR evaluation in POS women may help to identify patients with cardiovascular risk.

PURPOSE: to evaluate the factors leading to delays in obtaining definitive diagnosis of suspicious lesions for breast cancer. METHODS: a cross-sectional, observational study was carried out with 104 women attending a cancer hospital with a diagnosis or suspected diagnosis of breast cancer. A semistructured questionnaire on the patients' demographic, clinical characteristics and the use of services was applied.Variables were compared using t-Student test, Mann-Whitney test, Pearson's χ2 test or Fisher's exact test, as appropriate. In order to identify the variables associated with delays in breast cancer diagnosis, the Odds Ratio (OR) were calculated together with their respective 95% confidence intervals (95%CI) and a logistic regression model was constructed. RESULTS: age of patients was 54±12.6 years (mean±standard deviation). Most of the women were white (48.1%), married (63.5%), living in the city of Rio de Janeiro (57.7%) and poorly educated (60.6%). The median time between the first sign or symptom of the disease and first consultation was one month and the mean time between first consultation and confirmation of diagnosis was 6.5 months. In 51% of the women, diagnosis was late (stages II-IV). Symptomatic presentation and longer delay between symptom onset and the first evaluation and between symptom onset and the diagnosis were found to be significant factors (p<0.05) for delays in obtaining definitive diagnosis of suspicious lesions. CONCLUSIONS: the results of this study suggest that efforts must be made to reduce the time needed to get an appointment with a doctor and to confirm a diagnosis of suspicious lesions, as well as to educate physicians and the women themselves regarding the importance of breast symptoms and the value of prompt evaluation, diagnosis, and treatment.

PURPOSE: to evaluate risk factors for the development of genital prolapse in the Brazilian population. METHODS: case-control study involving 316 patients submitted to prolapse staging, according to the pelvic organ prolapse quantification system. The patients were divided into two groups: in the Case Group there were 107 patients with prolapse at stage III or IV, and in the Control Group, 209 women at stage 0 or I. In the anamnesis, the selected women have been questioned about the presence of possible risk factors for genital prolapse, such as: age, menopause age, parturition, delivery type (vaginal, caesarean section or forceps), occurrence of fetal macrosomia, family history of genital dystopia in first degree relatives, chronic cough and intestinal constipation. RESULTS: The variables that were different between the groups were: age, body mass index, parturition, number of vaginal, caesarean section or forceps deliveries, newborn weight and positive family history for prolapse. Race, menopause age, chronic cough and intestinal constipation did not present differences between the groups. After logistic regression, only three variables have been shown to be independent risk factors: presence of at least one vaginal delivery, fetal macrosomia and positive family history for dystopia. Cesarean section was shown to be a protective factor. CONCLUSION: in the Brazilian population, the independent risk factor for genital prolapse were: personal antecedent of at least one vaginal delivery, fetal macrosomia and family history of dystopia.

PURPOSE: to evaluate factors related to the presence of neonatal macrosomia in pregnant women with gestational diabetes mellitus. METHODS: 157 pregnant women presenting gestational diabetes mellitus in follow-up were retrospectively selected from January 2004 to July 2006. This group has been divided into two subgroups: one with newborns with weight in accordance with the gestational age (n=136) and another with macrosomic newborns (n=21). Maternal characteristics have been compared between the groups. The t-Student test was used for the analysis of equality hypothesis between the averages of the two groups, and chi-square test, to check the groups' homogeneity concerning ratios. RESULTS: the groups did not show any significant difference concerning the gestational age, body mass index, weight gain along the gestation, number of previous pregnancies, fast glycemia in the oral glucose tolerance test after the ingestion of 75 g (TOTG 75 g), gestational age at delivery, glycemic values during the treatment, and the type of treatment used (p>0.05). In the group with neonatal macrosomia, there was a higher two-hour-glycemia in the TOTG 75 g (p=0.02), higher gestational age at the treatment onset (p=0.02), and a lower number of appointments at the health service (p<0.01). When adjusted to a logistic regression model, the most important factor (p<0.01) found to predict neonatal macrosomia was the two-hour-glycemia in the TOTG 75 g. CONCLUSIONS: the factors more frequently related to neonatal macrosomia were late treatment onset and, consequently, lower number of appointments and chiefly, high two-hour-glycemia in the TOTG 75 g.

PURPOSE: to determine the prevalence and risk factors associated to anemia in pregnant women from the semiarid region of Alagoas, Brazil. METHODS: transversal study comprising a sample (n=150) obtained taking into consideration the prevalence estimated by World Health Organization of 52%, an error of 8% and a confidence interval of 95%. Sampling has been done in three stages: 15 towns among the 38 in the region, four census sectors by town and 24 residences by sector. All the resident pregnant women were eligible, and their socio-economic, demographic, anthropometric and health data have been collected. Anemia was identified at the <11 g/dL hemoglobin level (Hemocue®), and its association with risk factors, tested by multiple linear regression analysis. RESULTS: anemia prevalence was 50%. Seventy eight per cent of the pregnant women were under pre-natal care. From those, 79.3% were in the second or third trimester of gestation. Nevertheless, only 21.2% of them were taking iron supplementation. Variables (p<0.05) independently associated with anemia (anemic versus not-anemic pregnant women) were: larger number of family members (4.5±2.3 versus 4,3±2.3; p=0.02), lower age group of the pregnant woman (23.9±6.3 versus 24.7±6.7; p=0.04), or of her partner (34.5±15.8 versus 36±17.5; p=0.03), no toilet in the house (30.7 versus 24%; p<0.001), history of child abortion and/or death (32.4 versus 16.4%; p<0.001), living in the country (60 versus 46.7%; p=0.03), average per capita income

PURPOSE: to assess the prevalence and risk factors associated with near miss and other severe maternal morbidity at a reference tertiary maternity. METHODS: this is a cross-sectional study on severe maternal morbidity at the Hospital e Maternidade Celso Pierro, Campinas, São Paulo, between October 2005 and July 2006, identified from infirmary, admission and delivery unit logbooks. Pregnant and post-partum women with severe maternal morbidity were identified according to clinical criteria proposed by Waterstone. Later, cases with more severe morbidity, called extremely severe maternal morbidity, were reclassified using Mantel criteria, based on organic dysfunction and clinical management. RESULTS: there were 114 severe maternal morbidity cases among 2,207 birth deliveries, with a ratio of other severe morbidity and extremely severe morbidity near miss of 44.9 and 6.8 cases/1,000 live births, respectively. Mean gestational age at delivery was 35 weeks, and 87% came from the reference area for the maternity service. Hypertension (severe pre-eclampsia) represented 96% of other severe morbidity, while hemorrhage represented 60% of all extremely severe cases, followed by hypertension. The prevalence of extremely severe morbidity among the severe morbidity cases was not associated with marital status, schooling, maternal age, type of delivery, parity, gestational age at birth and home place. CONCLUSIONS: the other morbidities were 6.6 times more frequent than near miss, and it was not possible to differentiate both groups by epidemiological risk factors.
