PURPOSE: to evaluate associations between parental exposure to pesticides and births with congenital defects in São Francisco Valley, as well as the demographic profile and the defects found. METHODS: in this case-control study, each case (newborns with congenital defects) had two controls (healthy newborns). The subjects were born in the city of Petrolina, in São Francisco Valley, in 2009. The sample consisted of 42 cases and 84 controls. Data were gathered by a structured questionnaire adapted from Latin-American Collaborative Study of Congenital Malformations (ECLAMC), with the addition of questions related to exposure to pesticides, analysis of the medical records and contact with the hospital's pediatrician. The χ2 test was performed with a significance level of 5% to identify the variables with the greatest differences between case and control groups. Odds Ratio (OR) for the sample was calculated, as well as the OR obtained by logistic regression analysis, and finally, multivariate logistic regression analysis was performed. RESULTS: there was a greater exposure to pesticides during pregnancy in infants with congenital defects compared to healthy subjects. Increased risk was observed when at least one parent was exposed to pesticides (adjusted OR = 1.3; 95%CI = 0.4 - 3.9). The sociodemographic variables associated with congenital defects were: low school level, low weight, prematurity, young parents, chronic diseases, and physical factors. Multiple malformations and defects of the musculoskeletal and nervous systems were more frequently found. CONCLUSIONS: the present study suggests an association between exposure to pesticides and the occurrence of congenital defects, although the data were not significant.

PURPOSE: to evaluate the impact of dietary counseling on controlling weight gain in pregnant women, who were served in a public health service facility. METHODS: the study was conducted at a known health unit located in the metropolitan region of the city of Porto Alegre, in Rio Grande do Sul, Brazil. Three hundred and fifteen pregnant women between the 10th and 29th week of gestation were randomized to Control and Intervention Groups. The Intervention Group received dietary counseling according to nutritional status, and pregnant women in the Control Group were instructed to follow the routine of the health service facility. Weight and height were measured, and the body mass index (BMI) was calculated. The pre-gestational nutritional status was determined according to the following BMI criteria: low weight (<18.5 kg/m²), eutrophy (18.5 to 24.9 kg/m²), overweight (25.0 to 29.9 kg/m²), and obesity (>30 kg/m²). The nutritional status during pregnancy was determined according to the BMI curve for gestational age adopted by the Health Ministry of Brazil. Data were analyzed by the relative risk and respective 95% confidence interval, and by the Student's t-test and χ2 test. Statistical significance was set at p<0.05. RESULTS: the assessment of nutritional status before pregnancy showed that 28.0% of the women were overweight and 4.1% were underweight. In the first and last interview during pregnancy, the rates of prevalence of excessive weight were 36.2 and 46.0%, respectively. The intervention proved to be effective in reducing the rate of weekly weight gain of pregnant women with excess weight (342.2 versus 420.2; p=0.015) and the prevalence of clinical complications (9.2 versus 24.85; p<0.001). CONCLUSIONS: dietary counseling was effective in decreasing the weight gain of pregnant women who were overweight and reducing clinical complications, such as gestational diabetes, preeclampsia, infant low weight, and prematurity in the Intervention Group.

PURPOSE: to evaluate the concordance rate of ultrasound-guided core needle biopsy followed by excisional biopsy in palpable breast lumps, suggestive of fibroepithelial tumors. METHOD: a retrospective study included 70 biopsies with a histological diagnosis of fibroepithelial tumor in 67 out of 531 patients with breast lesions submitted to ultrasound-guided core needle biopsy with a high frequency (7.5 MHz) linear transducer, using an automatic Bard-Magnum gun and a 14-gauge needle. Cases with a diagnosis of fibroepithelial tumor by core needle biopsy or excisional biopsy and with a diagnosis of fibrosclerosis were included in the study. The agreement between the two biopsy methods was assessed using the Kappa coefficient. RESULTS: excisional biopsy revealed 40 cases of fibroadenoma (57.1%), 19 cases of phyllodes tumor (27.2%), and 11 cases of fibrosclerosis (15.7%). The concordance rate for fibroadenoma was substantial (k = 0.68, 95%CI = 0.45 - 0.91), almost perfect for the phyllodes tumor (k = 0.81, 95%CI = 0.57 - 1.0), and moderate for fibrosclerosis (k = 0.58, 95%CI = 0.36 - 0.90). CONCLUSIONS: the core needle biopsy is a minimally invasive method that has "substantial" to "almost perfect" concordance rate with excisional biopsy. Fibrosclerosis should be considered in the differential diagnosis of fibroepithelial tumors.

PURPOSE: to evaluate the frequency of TP53 codon 72 polymorphism in infertile women with endometriosis, women with idiopathic infertility, controls and its relation to the disease. METHODS: a case-control study that included 198 infertile women with endometriosis, 70 women with idiopathic infertility and 169 fertile women without endometriosis as control. Detection of TP53 codon 72 gene polymorphism (rs1042522, Arg/C:Pro/G), that promotes a C/G exchange in the coding region of the gene, was performed by real time Polymerase Chain Reaction (PCR), using the TaqMan system of primers, that flank the implicated region and probes labeled with different fluorescent dyes, one for allele C and other for allele G. When two dyes were observed, the patient was considered to be heterozygous CG. In the presence of only one dye, the individual was considered to be homozygous CC or GG. 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 to be statistically significant. RESULTS: we found no statistically significant difference in the distribution of TP53 codon 72 polymorphism genotypes CC, CG or GG (p=0.7) and alleles C or G (p=0.4) between infertile patients with endometriosis and controls (p=0.4), regardless of the stage of the disease. In relation to infertility, no statistically significant difference in the genotype or allele distribution (p=1.0 and p=0.9, respectively) was observed between idiopathic infertile women and controls. Considering the dominant inheritance model, again, no statistically significant difference was found even in the endometriosis (p=0.5) or the idiopathic infertility group (p=0.9) when compared to controls. Regarding the recessive inheritance model no statistically significant difference was found, with p=0.6 and p=1.0, respectively, for the endometriosis and idiopathic infertility groups. CONCLUSION: the results suggest that the TP53 codon 72 polymorphism does not confer genetic susceptibility to endometriosis and/or infertility in the Brazilian population, not even the severe form of the disease.
