PURPOSE: to compare the double-circle (DC) technique to other techniques, with periareolar (PA) and transverse nipple-areolar (TNA) incisions, for the surgical correction of gynecomastia. METHODS: we studied the medical files of 34 patients from the Federal University of Goiás, submitted to the surgical correction of gynecomastia, from 1999 to 2004. Patients were divided according to the surgical technique used. The parametric numeric variables were compared by Tukey test. The chi2 or the Fisher's exact test was used for nominal variables. It was considered significant a p value<0.05. RESULTS: the mean age of the patients was 27.9 (+12.5) years. There were 43 gynecomastias, 34 unilateral (79.1%) and nine (20.9%) bilateral. There were 19 breasts operated (44.2%) using DC, 14 (33.6%) using PA incision, and 10 (23.3%), TNA incision. The mean drain usage was five days for DC and one day for the others (p<0.01). The suction drain was used in 19 cases (100%) of DC and two (22%) in TNA. The other patients used drains of Penrose (p<0.01). The mean surgical time was significantly larger for DC (73 minutes) than for PA (45 minutes) and for TNA (48 minutes). DC was used mainly in voluminous gynecomastias (p=0.04). The complications consisted in three (33%) hematomas in TNA (p<0.01) and one (5%) in DC; one (11%) infection in TNA; two (10%) partial necrosis of the nipple in DC; four (21%) enlarged scars in DC (p=0.04); three (16%) hypertrofic scars (p=0.08) in DC; one (2%) inversion of nipple with TNA. CONCLUSIONS: The DC was used often in voluminous gynecomastias. It was a good and secure operation, although it required a more extensive surgical time and had a larger possibility of distended scars.

PURPOSE: to assess the prevalence of the risk of post-partum depression in women in the post-natal ward of a hospital in São Paulo city, in the southeastern region of Brazil, and analyze the associated factors, including domestic violence (DV). METHODS: this was a descriptive, cross-sectional study. The participants were 133 women with at least 20 weeks of gestation age, who delivered their babies from August to September 2005 in a tertiary maternity in the city of São Paulo (Brazil). They were interviewed using the Portuguese version of the Abuse Assessment Screen for the diagnosis of violence and filled out a self-evaluation questionnaire for post-partum depression (Edinburgh Postnatal Depression Scale). Variables were presented as absolute and relative frequencies. The chi2 or Fisher exact tests were used to analyze possible associations between the variables of interest and post-partum depression. The value of 5% was considered significant. RESULTS: risk for post-partum depression was detected in 24 women (18%). A total of 38.3% of the participants interviewed had a history of abuse. There was an association between DV after they were 15 years old and risk of depression (p=0.036). The prevalence of abuse in the group of women at risk for post-partum depression was 58.3% and this was significantly higher than the 33.9% observed in the control group. CONCLUSIONS: the probability of presenting depression was high among the post-partum women attended at a tertiary maternity in the southeast of Brazil. The DV after they were 15 years old was significantly associated with risk of post-partum depression.

PURPOSE: to quantify the presence of antithyroperoxidase (anti-TPO) and antithyroglobulin (anti-TG) antibodies, and the plasmatic concentrations of thyrotropin (TSH) and free thyroxine (FT4) in normal pregnant women. METHODS: a hundred twenty-seven pregnant women, residing in São Paulo, aged from 14 to 44 years old and gestational age > 16 weeks, determined by ultrasound performed before the 20th week of pregnancy were included in a transversal study performed in the prenatal clinic of Santa Casa de Misericórdia de São Paulo, from January 2003 to September 2004. Pregnant women using medicines or with thyroidopathy history were excluded. Antithyroperoxidase and antithyroglobulin antibodies were quantified by chemiluminescence immunoassay. The immunofluorimetry technique by time-resolved was used for determining the thyrotrophin and free thyroxine. The Student's t test, with significance of 5%, was used for analyzing the results. RESULTS: the frequency of antithyroid antibodies was 12.6% (8.6% of anti-TPO antibodies, and 4.6% of anti-TG antibodies). The average of TSH concentrations was 2.13±1.0 µU/ml, and the average of T4L was 0.9±0.5 ng/dl. It was observed alteration of the thyroid function in ten pregnant women (8%). Three of them had diagnosis of hypothyroidism: one in the clinical form of the disease, with increased TSH and decreased FT4; two in the subclinical form with increased TSH and normal FT4. Five presented decreased TSH and increased FT4, consistent with clinical hyperthyroidism and two were diagnosed with subclinical hyperthyroidism, with decreased TSH concentrations only. CONCLUSIONS: the frequency of antithyroid antibodies was 12.6% in pregnant women, the antithyroperoxidase antibodies being predominant over the antithyroglobulin antibodies. It was observed some thyroid dysfunction in 8% of the cases with alterations of TSH and/or T4L.

PURPOSE: to translate and to validate the Female Sexual Function Index (FSFI) for Brazilian pregnant women. METHODS: ninety-two pregnant women attended at a low risk prenatal clinic, with diagnosis of the pregnancy confirmed by precocious ultrasonography, participated in the research. Initially, we translated the FSFI questionnaire for Portuguese language (of Brazil) in agreement with the international criteria. Cultural, conceptual and semantics adaptations of FSFI were accomplished, because of the differences of the language, so that the pregnant women understood the subjects. All the patients answered FSFI twice, in the same day, with two different interviewers, with an hour interval from one to other interview. After 7 to 14 days, the questionnaire was applied again in a second interview. Reliability (internal intra and interobserver consistence) and the validity of the constructo (to demonstrate that questionnaire measures the sexual function) were appraised. RESULTS: Cultural adaptations were necessary for us to obtain the final version. The internal intra-observer (alpha of Chronbach) consistence of the several domains oscillated from moderate to strong (0,791 to 0,911) and the interobserver consistence varied from 0,791 to 0,914. In the validation of the constructo, were obtained moderate correlations to fort among the final scores (general) of FSFI and of Female Sexual Quotient (QS-F) that has the capacity to evaluate the feminine sexual function. CONCLUSIONS: FSFI was adapted to the Portuguese language and to the Brazilian culture, presenting significant reliability and validity; it could be included and used in future studies of the Brazilian pregnant sexual function.

PURPOSE: to evaluate fetal maternal complications after chorionic villus sampling (CVS) for prenatal diagnosis of genetic disorders in pregnant women of Salvador (BA), Brazil. METHODS: case-series study of 958 pregnancies with high risk for chromosomal abnormality submitted to CVS transabdominal between the ninth to the 24th week of gestation, using an ultrasound-guided 18G 3½ spinal needle, from 1990 to 2006. The variables for the analysis of immediate complications were uterine cramps, subchorionic hematoma, accidental amniotic cavity punction, pain in the punction area, amniotic fluid leakage, abdominal discomfort, fetal arrhythmias and vaginal bleeding, and of late complication, abdominal pain, vaginal bleeding, amniotic fluid leakage, infection and spontaneous miscarriage. Premature labor, obstetrical complications (abruption placenta and placenta previa) and newborn malformation were also studied. Qui-square, Student’s "t" or Mann-Whitney tests were used for the statistical analysis; the significance level was 5%. RESULTS: maternal mean age was 36.3±4.9 years old. Immediate complications ware found in 182 (19%) cases (uterine cramp in 14%, subchorionic hematoma in 1.8% and accidental amniotic cavity punction in 1.3%). Late complications were found in 32 (3.3%) cases (vaginal bleeding in 1.6%, abdominal pain in 1.4%, amniotic fluid leakage in 0.3% and spontaneous miscarriage in 1.6% cases). There was no case of abruption placentae, placenta previa or fetal malformation. CONCLUSIONS: CVS is a simple and safe procedure. CVS should be performed in high risk pregnant patients who need prenatal diagnosis of fetal chromosomal abnormalities.

PURPOSE: to identify the main maternal risk factors involved in early-onset neonatal sepsis, evaluating the risk associations between bacterial vaginosis and isolated microorganisms found in the maternal urine culture and in the newborn blood culture in the delivery room. METHODS: randomized longitudinal cohort study involving 302 mothers and their newborns. All neonates were followed up for seven days in order to diagnose sepsis. RESULTS: the outcomes were the following: 16 (5.3%) early-onset neonatal sepsis cases (incidence of 53 cases per 1,000 live births). The average number of prenatal appointments with a doctor was 5.2 (SD=1.8). The number of women with prenatal follow-up was 269 (89.1%), but only 117 (43.4%) of them went to six or more medical appointments, 90 (29.8%) had premature rupture of membranes before delivery, but only 22 (7.3%) had it for more than 18 hours. A total of 123 women (40.7%) complained of vaginal discharge, but only 47 (15.6%) of them had bacterial vaginosis, 92 (30.4%) complained of urinary infection, but only 23 (7.6%) of them had bacteriuria, two (0.7%) had fever at home, 122 (40.4%) received intra-partum antibiotic prophylaxis, 40 (13.2%) had premature delivery and 37 (12.3%) had low-birth-weight babies. Gestational age was a significant risk factor (RR=92.9; IC95%:12.6-684.7), as well as the number of prenatal appointments (RR=10,8; IC95%:1,4-80,8), fever (RR=10,0; IC95%:2,3-43,5), low-birth-weight (RR=21,5; IC95%:7,3-63,2) and early neonatal death (RR=89,4; IC95%:11,16-720,6). A significant difference of 5% was found in the comparison of the averages of lower number of prenatal appointments, prematurity and lower birth weight. CONCLUSIONS: the major microorganism isolated in the newborns’ blood culture was the Streptococcus agalactiae. Prematurity, lack of prenatal follow up and low birth weight were the risk factors more associated with early neonatal sepsis.

PURPOSE: to evaluate the efficiency of the 100% rapid rescreening in the detection of false-negative results and to verify whether the results vary according to the adequacy of the sample and the woman’s age group. METHODS: to evaluate the efficiency of the rapid rescreening, the 5,530 smears classified as negative by the routine screening, after being submitted to the rapid rescreening of 100%, were compared with the rescreening of the smears on the basis of clinical criteria and 10% random rescreening. For statistical analysis, the variables were evaluated descriptively and the c² test and the Cochran-Armitage test were applied to compare results. RESULTS: of the 141 smears identified as suspicious according to the rapid rescreening method, 84 (59.6%) cases were confirmed in the final diagnosis, of which 36 (25.5%) were classified as atypical squamous cells of undetermined significance, five (3.5%) as atypical squamous cells that cannot exclude high-grade squamous intraepithelial lesion, 34 (24.1%) as low-grade squamous intraepithelial lesion, six (4.3%) as high-grade squamous intraepithelial lesion, and three (2.1%) as atypical glandular cells. Of the 84 suspect smears confirmed in the final diagnosis, 62 (73.8%) smears were classified as adequate and 22 (26.2%) as adequate but with some limitation, but no significant difference was observed with the woman’s age. CONCLUSIONS: the results of this study show that rapid rescreening is an efficient option for internal quality control for the detection of false-negative cervical smear results. In addition, it should be noted that rapid rescreening performed better when the sample was classified as adequate for analysis; however, it did not vary according to the woman’s age group.

PURPOSE: to analyze the macroscopic and histological changes that occur with the use of sinvastatin in experimental endometriosis in female rats. METHODS: forty Wistar female rats were submitted to the technique of uterine self-transplant in mesenterium. After three weeks, 24 of them developed experimental endometriosis grade III, and were divided in two groups: one group received sinvastatin orally (20 mg/kg/day) and the other (control group) received 0.9% of sodium chloride orally (1 mL/100 g of body weight/day). Both groups received gavage for 14 days, followed by death. The implant volume was calculated [4pi (lenght/2) x (width/2) x (height/2)/3] at the surgical intervention and after the animal’s death. The self-transplants were removed, dyed with hematoxylin-eosin and analyzed by light microscopy. The Mann-Whitney’s test was used in the independent samples and the Wilcoxon’s test for the related samples. The Fisher’s exact test was used for the histological evaluation, with a significance level of 5%. RESULTS: the difference between groups of the initial average volumes of the self-transplants was not significant (p=1.00), but became significant for the final average volumes (p=0.04). There was a significant increase (p=0.01) between the initial and final average volumes in the control group, and a no significant decrease in the sinvastatin group (p=0.95). Histologically, the sinvastatin group (n=9) presented seven cases (77.8%) of moderately preserved and two cases (22.2%) of well preserved epithelial wall, while the control group (n=12) presented seven cases (58.3%) of moderately preserved and five cases (41.7%) of well preserved epithelial wall. CONCLUSIONS: sinvastatin prevented the growth of experimental endometriosis. Studies with sinvastatin for longer periods are promising.
