PURPOSE: the aim of the present study was to evaluate the accuracy of microalbuminuria to predict preeclampsia. METHODS: a prospective study of 45 consecutive diabetic gestations that were tested for microalbuminuria before the 18th week, between the 18th and 24th week and between the 32nd and 36th week of gestation. All patients had their prenatal care done from January 2000 to December 2001. The DCA 2000 microalbumin/creatinine assay is a quantitative method for measuring low concentrations of albumin, creatinine and the albumin/creatinine ratio in urine. According to laboratory standards, an albumin/creatinine ratio >16 mg/g (1.8 mg/mmol) indicates incipient renal damage and risk for preeclampsia. The sensitivity, specificity, positive and negative predictive values of the albumin/creatinine ratio were determined to predict the occurrence or the absence of preeclampsia, diagnosed through clinical criteria. RESULTS: of all patients, 17% developed preeclampsia. The sensitivity of albumin/creatinine ratio increased from 12.5% at 18 weeks to 25% between the 18th and 24th week and to 87% after the 32nd week. On the other hand, specificity presented a decreasing value from 97 to 89 and 83%, respectively). The positive predictive value was relatively low in the three different periods of evaluation (50, 33 and 53%, respectively. The negative predictive value was increased in the three stages of gestational age (83, 84 and 96%, respectively). CONCLUSIONS: quantification of microalbuminuria could correctly predict the absence of preeclampsia but was less accurate to predict the occurrence of the disease in diabetic pregnancies.

Objective: to test the effectiveness of the polymerase chain reaction (PCR) in the amniotic fluid for the detection of fetal contamination due to Toxoplasma gondii in pregnant women with acute infection and to correlate it with the inoculation technique and the histology of the placenta. Methods: thirty-seven patients were prospectively studied and the diagnosis was based on the identification of maternal acute infection followed by amniocentesis guided by ultrasound to obtain amniotic fluid for PCR and mice inoculation. The mothers were treated with spiramycin throughout pregnancy; when fetal infection was demonstrated, pyrimethamine and sulfadiazine were added to the regimen. The placentas were processed for histologic examination. The infants were followed for a period that varied from three to 23 months for the confirmation or exclusion of congenital toxoplasmosis. Results: association measures such as sensitivity, specificity and predictive values were calculated for PCR in the amniotic fluid, detection of the parasite through mice inoculation and placental histology and showed the following results: PCR values of sensitivity = 66.7% and specificity = 87.1%; the respective values for mice inoculation were 50 and 100% and for the placental histology were 80 and 66.7%. Conclusion: although PCR should not be used alone for the prenatal diagnosis of congenital toxoplasmosis, it is a promising method and deserves more studies to improve its efficacy.

to analize the level of functional fitness of a group of postmenopausal women in
the city of Presidente Prudente using the set of functional fitness tests of the
American Alliance for Health, Physical Education, Recreation and Dance and to
check whether there are differences between groups of women in the fifth and sixth
decade of life.
This was a cross-sectional study conducted on 175 postmenopausal women (follicle
stimulating hormone level>26.72 mIU/L) in the city of Presidente Prudente in
2013. The inclusion criteria were not being part of any type of systematic motor
intervention for at least six months before the collection of research data;
absence of motor or cognitive impairment that would prevent the evaluation
protocols, and absence of chronic or degenerative disease, musculoskeletal injury
or comorbidity that could prevent or limit the evaluations. The women were
evaluated by the same trained examiners. The 50 to 59 year group showed a mean age
of 55.3±4.5 years, mean FSH values of 53.5±21.1 mIU/mL, mean coordination of
11.4±2.2 seconds, mean strength of 20.1±3.9 repetitions, mean flexibility of
51.7±11.8 cm, mean 23.2±2.8 seconds agility and mean aerobic resistance of
500±43/2 . The 60 to 69 year group had a mean age of 65.1±4.1 years with FSH
54.9±15.9, 11.6±2.6 seconds coordination, strength 20.3±4.7 repetitions, 54.6±11.2
cm flexibility, agility 24.7±4.3 seconds, and aerobic resistance of 508±51
seconds.
It was possible to analyze the functional fitness of postmenopausal women through
the set of the American Alliance testing for Health, Physical Education,
Recreation and Dance with no significant differences between groups for the
variables strength, flexibility, aerobic capacity and coordination, and with only
the speed variable showing significant differences. We recommend further studies
seeking to formulate normative values for the population in question.

PURPOSE: to analyze race, parity and presence of the progesterone receptor polymorphism, named PROGINS, as factors related to uterine leiomyoma occurrence in Brazilian women. METHODS: we carried out a case-control study, composed of 122 patients with the diagnosis of uterine fibroid and 125 women without the disease. After recording the clinical data, we collected biological material for DNA extraction, polymerase chain reaction and agarose gel electrophoresis in order to identify the presence of PROGINS polymorphism. Statistical analysis was performed using the non-parametric Mann-Whitney test or the chi2 test, depending on the studied variable. The risk for the occurrence of the disease was calculated by the logistic regression model, providing the odds ratio (OR). The adopted significance level was 5% (p<0.05) and the confidence interval was 95% (95% CI). RESULTS: we observed a higher prevalence of "non-white"women - mulatto and black - (50 vs 22.4%) and nulliparas (23.8 vs 11.2%) in the cases, while the progesterone receptor genotype was more often PROGINS positive - heterozygous or mutant homozygous - among the controls (21.6 vs 10.7%). The OR indicated an elevated risk for leiomyoma related to the "non-white"race (OR=3.46; 95% CI: 2.0-6.0) and the nulliparity (OR=3.30; 95% CI: 1.9-5.6), with reduction in the presence of PROGINS-positive genotypes (OR=0.43; 95% CI: 0.2-0.9). CONCLUSIONS: the "non-white"race and nulliparity were considered risk factors for the occurrence of uterine fibroid in the studied population, while PROGINS polymorphism showed to be a protective factor.

PURPOSE: To evaluate the anatomical distribution of deep infiltrating endometriosis (DIE) lesions in a sample of women from the South of Brazil. METHODS: A prospective study was conducted on women undergoing surgical treatment for DIE from January 2010 to January 2012. The lesions were classified according to eight main locations, from least serious to worst: round ligament, anterior uterine serosa/vesicouterine peitoneal reflection, utero-sacral ligament, retrocervical area, vagina, bladder, intestine, ureter. The number and location of the DIE lesions were studied for each patient according to the above-mentioned criteria and also according to uni- or multifocality. The statistical analysis was performed using Statistica version 8.0. The values p<0.05 were considered statistically significant. RESULTS: During the study period, a total of 143 women presented 577 DIE lesions: uterosacral ligament (n=239; 41.4%), retrocervical (n=91; 15.7%), vagina (n=50; 8.7%), round ligament (n=50; 8,7%), vesico-uterine septum (n=41; 7.1%), bladder (n=12; 2.1%), and intestine (n=83; 14.4%), ureter (n=11; 1.9%). Multifocal disease was observed in the majority of patients (p<0.0001), and the mean number of DIE lesions per patient was 4. Ovarian endometrioma was present in 57 women (39.9%). Sixty-five patients (45.4%) presented intestinal infiltration on histological examination. A total of 83 DIE intestinal lesions were distributed as follows: appendix (n=7), cecum (n=1) and rectosigmoid (n=75). The mean number of intestinal lesions per patient was 1.3. CONCLUSIONS: DIE has a multifocal pattern of distribution, a fact of fundamental importance for the definition of the complete surgical treatment of the disease.
