PURPOSE: to verify the occurrence of colonization by Streptococcus agalactiae in pregnant women attended at the prenatal outpatient clinic of the Teaching Maternity Hospital of Rio de Janeiro University (UFRJ) and to evaluate the susceptibility of the isolates to antimicrobial agents. METHODS: a total of 167 pregnant women between the 32nd and 41st week of gestation, regardless of risk factors, attended at the antenatal clinic between February 2003 and February 2004, were evaluated. The vaginal/anal material, collected by the same swab, was inoculated in Todd-Hewitt broth to which nalidixic acid (15 µg/mL) and gentamicin (8 µg/mL) were added, with following subcultures onto sheep blood-agar. Identification was carried out observing colony morphology and beta-hemolysis type on blood-agar, catalase, cAMP, and serological tests. The antimicrobial susceptibility testing used agar diffusion and agar dilution methods. Statistical analysis was performed by the chi2 test with the level of significance set at p<0,05. RESULTS: the frequency of colonization was 19.2%, with no significant differences when age, number of gestations, number of abortions and the presence or absence of diabetes mellitus were compared (p>0.05). All 32 isolated strains were susceptible to penicillin, cefotaxime, ofloxacin, chloramphenicol, vancomycin and meropenem. Resistance to erythromycin and clindamycin was detected in 9.4 and 6.2% of the isolates, respectively. CONCLUSIONS: the relatively high incidence (19.2%) of colonization by S. agalactiae among the evaluated pregnant women and the recovery of antimicrobial resistant strains, especially those recommended in cases of penicillin allergy, emphasize the importance, for a correct prevention of neonatal infections, of detecting colonization at the end of pregnancy and evaluating antimicrobial susceptibility.

PURPOSE: to identify risk factors for fetal macrosomia in pregnant women with diabetes or daily hyperglycemia. METHODS: retrospective study, control-case, including 803 pairs of mothers and newborns belonging to this specific population, divided into two groups - macrosomic (cases, n=242) and non-macrosomic (controls, n=561). Variables regarding age, parity, weight and body mass index (BMI), weight gain (WG), diabetes history, high blood pressure and tabagism, diabetes type and classification, and glycemic control indicators in the third trimester were compared. The means were evaluated by the F test and the categorized variables were submitted to univariate analysis using the chi² test. The significative results were included in the multiple regression model for the identification of macrosomia independent risk considering OR, 95% CI and p value. The statistical significance limit of 5% was established for all analyses. RESULTS: there was a significative association between macrosomia and WG >16 kg, BMI >25 kg/m², personal, obstetric and macrosomic history, classification in the Rudge groups (IB and IIA + IIB), glycemic mean (GM) >120 mg/dL and postprandial glycemic mean >130 mg/dL in the third trimester. In the multiple regression analysis, WG >16 kg (OR=1,79; 95% CI: 1,23-1.60), BMI >25 kg/m² (OR=1.83; 95% CI: 1.27-2.64), personal history of diabetes (OR=1.56; 95% CI: 1.05-2.31) and of macrosomia (OR=2.37; 95% CI: 1.60-3.50) and GM >120 mg/dL in the third trimester (OR=1.78; 95% CI: 1.13-2.80) confirmed to be independent risk factors for macrosomia in these pregnancies. CONCLUSION: WG >16 kg, BMI >25 kg/m², GM >120 mg/dL in the third trimester and personal history of macrosomia and diabetes were identified as risk factors for fetal macrosomia in pregnant women with diabetes or daily hyperglycemia.

PURPOSE: to evaluate the prevalence of intrauterine adhesions after manual vacuum aspiration for the treatment of abortion. METHODS: a prospective, descriptive study, with group comparison was carried out between November 2000 and August 2001 on 80 women between 15 and 48 years old, admitted to a public hospital for abortion care. Manual vacuum aspiration consisted of extracting the uterine content by suction using a Karman syringe connected to plastic cannulas. Intrauterine adhesions were screened by hysteroscopy, performed 40-60 days after the aspiration. Statistical analysis was performed using Fisher exact test, ANOVA and estimation of prevalence risk, when indicated. RESULTS: hysteroscopy identified intrauterine adhesions in 13 patients (prevalence = 16.3%), most of them of the mucosal type (9 of 13), minimal severity (11 of 13) and lateral location in the uterus (5 of 13). Adhesions were more frequent at a gestational age more than 8 weeks (24.4 vs 3.7%; prevalence risk of 6.6) as well as in missed abortion (41.7 vs 12.1% ; prevalence risk of 3.54). CONCLUSIONS: prevalence of intrauterine adhesions after manual vacuum aspiration was 16.3%. Missed abortion and advanced gestational age seem to be associated with the occurrence of adhesions.

PURPOSE: to verify if there is any difference in the number of miscarriages and newborns with low weight in patients with scleroderma (SSc) when compared with women without the disease, between the two clinical variants of the disease and when the expression of SSc occurred before or after the gestation. METHODS: twenty-six patients were analyzed regarding the number of pregnancies, miscarriages, sex, and birth weight of the children, studying the clinical variant of the disease and the temporal relationship between diagnosis and gestation. The patients had not used either medications that could interfere in gestation or had any other disease that could do it. For control, twenty-six healthy women, without diseases that might alter the gestation, of the same ages and socioeconomic status were studied. For the statistical analysis study, tables of frequency, tables of contingency, and Fisher, chi2 and Mann-Whitney tests were used. Statistical significance was considered when p<0.05. RESULTS: among the patients with SSc, there were 96 gestations with 13.5% (n=13) of miscarriages. In the control group, there were 94 gestations with 9.6% (n=9) of miscarriages. There were no differences in the number of newborns with low weight between the two groups (cases, n=8 and controls, n=6, with p=0.54), nor in the number of miscarriages (p=0.46). However, the number of newborn babies with low weight was significantly higher among the cases with the diffuse disease (diffuse form, n=4 and limited, n=4, with p=0.04) and among patients that became pregnant after the diagnosis of SSc (37.5% in women known to be sick and 6.7% in women who became pregnant before getting ill, with p=0.03). The number of male newborns was higher in the women with SSc (p=0.002). CONCLUSIONS: the women with SSc showed a higher number of low-weight newborns in the group with diffuse disease and when pregnancy occurred after the clinical diagnosis of the disease.

PURPOSE: comparative analysis of the outcome of women with advanced pelvic endometriosis and women with tubal sterilization submitted to intracytoplasmic sperm injection (ICSI). METHODS: ninety-three infertile women, with normal menstrual cycle, without hormonal or surgical treatment during 12 months, body mass index of 20-25, ovaries with no tumors or cysts were included in the present study and divided into two groups: tubal sterilization (TUB), 39 women, and endometriosis (EDT), 54 women with III-EDT and IV-EDT, undergoing ovulatory induction using r-FSH and ICSI. Clinical and laboratorial data were compared. chi2, Fisher, Student's t, and Mann-Whitney tests were employed. RESULTS: lower estradiol levels (2,243.1 vs 1,666.3; p=0.001) and lower number of follicles per patient (16.9 vs 13.9, p=0.001) were noted in EDT group, in spite of more units of r-FSH (1,775.6 vs 1,998.6; p=0.007, for TUB and EDT, respectively). There were no differences in the rates of retrieved oocyte (69 vs 73.5%; p=0.071) as well as in normal fertilization rates (83.7 vs 81.7%; p=0.563, for TUB and EDT, respectively. However, lower number of top quality preembryos were obtained in patients from EDT group (36.5 vs 24.8%, TUB and EDT, respectively; p=0.005). Total pregnancy (41.0 vs 42.6%; p=0.950) and implantation rates (13.9 vs 14.5%; p=0.905) were not different when groups TUB and EDT were compared. CONCLUSIONS: ovaries of women from EDT group seem to be less responsive to ovulatory induction with r-FSH. EDT seems to impair the mean number of follicles and top quality preembryos with no impairment of retrieved oocyte and fertilization rates. However, once obtained, preembryos from EDT patients are able to exhibit similar implantation potential and pregnancy when compared with patients from TUB group.

PURPOSE: to test the hypothesis that gene TP53 codon 72 polymorphism is a risk factor for premalignant and malignant cervical lesions associated or not with human papillomavirus (HPV). METHODS: uterine cervical samples were collected for HPV DNA and TP53 codon 72 polymorphism tests from 155 patients who underwent cervical biopsy. Three groups were formed according to histological diagnosis: low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL) and cervical carcinoma. Subjects without cytological and histological displasic changes were considered controls. To verify the association between the gene TP53 codon 72 polymorphism and the groups, the chi2 test was applied. Confidence interval was considered significant at 95% (alpha=0.05). RESULTS: forty subjects were found to present cervical carcinoma, 18 had HSIL, 24 had LSIL and 73 were grouped as controls. The genotype Arg/Arg p53 was found in 60% of the patients with cancer, in 50.0% of the cases with HSIL, 45.8% with LSIL, and in 45.2% of the controls. No significant differences were identified in the frequencies of p53 genotype between all groups, independently of the presence of HPV (chi2: 3.7; p=0.716). CONCLUSIONS: our data do not support hypothesis that the gene TP53 codon 72 polymorphism is important for the development of pre-malignant and malignant cervical lesions associated or not with HPV.

PURPOSE: to evaluate the results of 14 cases of laparoscopic surgical treatment of patients with deep endometriosis of the rectovaginal septum in the Sector of Gynecological Endoscopy of the 'Hospital do Servidor Público Estadual "Francisco Morato de Oliveira"'. METHODS: a retrospective analysis was accomplished with data from the records, associated with postoperative evaluation of the patients operated between February 2002 and February 2004. The patients' age varied from 33 to 44 years, with a mean of 38.4. The parity ranged from 0 to 3, with a mean of 1.1. The main preoperative symptoms were: dysmenorrhea in 14 (100%), deep dyspareunia in 12 (85.7%), non-ciclic pelvic pain in 10 (71.4%), pain at defecation in two (14.3%), rectal bleeding in two (14.3%), and infertility in two (14.3%). The plasma level of CA-125 ranged from 3.6 to 100.3 U/mL, with a mean of 52.9 U/mL. RESULTS: the histological examination of the lesions of the rectovaginal septum was compatible with endometriosis in nine (64.3%) patients. Concerning painful symptoms, there was total regression in seven (50%) patients, partial regression (more than 80% relief) in two (14.3%), no improvement in four (28.6%), and worsening in one (7.1%). The incidence of complications was 14.3%: a ureter lesion associated with lesion of the sigmoid and a lesion of the rectum diagnosed on the 8th postoperative day. Conclusion: it can be concluded that endometriosis of the rectovaginal septum can be treated through laparoscopic surgery with low morbidity, leading to a complete or almost complete relief of the symptoms in most of the patients.
