PURPOSE: to compare the pain reported by patients submitted to hysteroscopy by the standard technique with carbon dioxide (CO2) and to vaginal hysteroscopy with physiological saline (0.9% NaCl). METHODS: this was a prospective cohort study conducted at an ambulatory hysteroscopy service. A total of 117 patients with indication for the exam were included, being randomly assigned to one of the groups. All patients answered an epidemiological questionnaire and scored the pain expected before the exam and that felt after the end of the procedure on a verbal pain scale from 0 to 10. A speculum, traction of the cervix, insertion of a 30º light source and a diagnostic shirt with a total diameter of 5 mm were used for the standard technique. The cavity was distended with CO2 under a pressure of 100 mmHg controlled with a hysteroflator, and a biopsy was obtained with a Novak curette. Vaginoscopy was performed without a touch by distention of the vagina with fluid, direct visualization of the cervix and introduction of the light source with two continuous-flow shirts, with an accessory channel with an oval profile, the whole set measuring 5 mm in diameter. The medium distention was 0.9% NaCl and the pressure used was that considered to be necessary for an adequate visualization of the canal and of the cavity with an external pneumatic pressurizer. The biopsy was obtained in a directed manner using an endoscopic clamp. The mean and standard deviation were calculated for the quantitative variables and the frequency was calculated for the qualitative variables. The Student's t-test was used to compare the means, and the chi-square or exact Fisher test was used (when n<5) for the categorical analysis using the SPSS 15.0 software. The study was designed for a 95% test power, with the level of significance set at p<0.05. RESULTS: the groups were similar regarding age, parity, previous uterine surgeries, menopausal status, and the need for a biopsy. In comparison to the group submitted to the standard technique, the vaginoscopy group involved a lower technical difficulty (5.1 versus 17.2%, p=0.03), a higher rate of exams considered to be satisfactory (98.3 versus 89.7%, p=0.04) and a lower pain index (4.8 versus 6.1; p=0.01), as the difference were more evident when patients who never had a previous normal delivery were compared (4.9 versus 7.1; p=0.0001). When the pain scale was stratified as mild (0-4), moderate (5-7) or intense (8-10), the vaginoscopy technique was found to be associated with a 52% reduction of the frequency of intense pain (p=0.005). CONCLUSIONS: vaginohysteroscopy was proved to be a less painful procedure than the technique based on the use of a speculum and CO2, regardless of age, menopause or parity, with more satisfactory results and lower technical difficulty.

PURPOSE: to assess p53 protein expression in infiltrating ductal breast carcinoma and to analyze its association with histological and nuclear grade. METHODS: sixty-five consecutive females who were diagnosed with primary infiltrating ductal breast tumor from July 1999 to July 2001 were included in the present study. Mean patient age at diagnosis was 69.2 years (range 41 - 90). All patients were first treated with surgical therapy, conservative surgery or mastectomy. None of the patients received any preoperative adjuvant therapy. Resected breast tumor specimens were fixed in 10% formalin, paraffin embedded, and conserved for immunohistochemical analysis. p53 protein expression was evaluated. Primary monoclonal anti-human p53 antibody DO-7 (DAKO) was used. Frequency distributions were tested by the chi2 test. A level of p<0,05 was considered significant. RESULTS: p53 expression was detected in 24 (36,9%) of 65 carcinomas. Of the cases with protein expression, 13 (54,2%) were high or histological grade III, 8 (33,3%), were grade II, 3 (12,5%) were grade I. On nuclear grade analysis, of the cases with protein expression, 13 (4,2%) were nuclear grade III, 9 (37,5%) were grade II and 2 (8,3%) were grade I. p53 expression was frequent in carcinomas with high histological and nuclear grades. CONCLUSIONS: p53 expression was significantly associated with the histological grade. On the other hand, nuclear grade was not significantly related to p53 expression.

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.

PURPOSE: to analyze the correlation between PROGINS polymorphism and breast cancer. METHODS: a case-control study was carried out from April to October 2004. The genotypes of 50 women with breast cancer and 49 healthy women were analyzed. The 306-base pair Alu insertion polymorphism in the G intron of progesterone receptor gene was detected by polymerase chain reaction and analyzed on 2% agarose gel stained with ethidium bromide. The control and experimental groups were compared regarding genotypes using the statistical Epi-Info 6.0 program and for frequencies the exact Fisher test or chi2 test were used. p value smaller p than 5% was considered to be significant. RESULTS: in relation to PROGINS we found in the studied population a prevalence of 62 (62.6%) wild homozygous, 35 (35.3%) heterozygous individuals and two (2.1%) cases with the presence of the mutation. Regarding PROGINS polymorphism, significance was not evidenced when cases and controls were compared, as related to homozygosis (62 vs 65.3%), heterozygosis (36 vs 34,6%) or the mutation (2.0 vs 2.1%), with p=0.920 (OR=1.01), 0.891 (OR=1.06), and 0.988 (OR=1.10), respectively. CONCLUSIONS: the results show that single-gene PROGINS polymorphism does not confer a substantial risk of breast cancer to its carriers.

PURPOSE: to assess the interference of two vaginal lubricants (vaseline and silicone) in the interpretation of cervical oncotic cytology. METHODS: a prospective research on one hundred women from August to October 2003. The women were divided into two groups of 50 patients each, according to the type of lubricant used. Two smears were obtained from every patient: the first specimen soon after the introduction of non-lubricated speculum and the second after the use of lubricated speculum with vaseline (Group V) or silicone (Group S). The samples were analyzed by two cytotechnicians, who were unaware of the origin of the smears. RESULTS: among the 100 pairs of slides, 8 results were partially different. The reasons for the differences were not directly related to the use of lubricant and did not interfere with the cytologic findings. The number of discordant results was 6 in Group S and 2 in Group V, without a statistically significant difference (p=0.269). The number of satisfactory and satisfactory but limited results was statistically similar regarding the use or not of lubricant: Group S: 46 satisfactory slides and 4 satisfactory but limited slides (p=0.001 and kappa=0.802) and Group V: 48 satisfactory and 2 satisfactory but limited slides (p=0.001 and kappa=0.953). There were no unsatisfactory results. No artefacts were found in slides obtained with lubricated speculum. CONCLUSION: the use of lubricated speculum with vaseline or silicone does not affect cervical oncotic cytology outcome.

PURPOSE: to evaluate perinatal results in pregnant women over 35 years old and to check differences between two groups: 35 to 39-year-old women and women older than 40. METHODS: a retrospective survey was made during the period between January/2000 and July/2003, through the analysis of obstetric charts of 3,093 pregnant women who delivered in the "Hospital do Servidor Público Estadual - Francisco Morato de Oliveira", excluding 933 patients. The patients were divided into 3 groups: 18 to 29 years old (control group), 35 to 39 years old, and over 40 years old. Data collection was done with standardized forms, and the data were transferred to an electronic spreadsheet (Excel - Microsoft Office 2000). Statistical analysis was performed using the chi2 test and the Fisher test. The alpha risk was less or equal to 5% and the confidence interval 95%. RESULTS: cesarean section was the most used method not only in the 35 to 39-year-old group (438/792; 55.3%) but also in the group of women over 40 (153/236; 64.8%). The rates of prematurity (39/236; 16.5%), low weight (37/236; 15.7%), and restriction of fetal growth (38/236; 16.1%) were significantly higher in the group of women over 40, when compared to the other groups. Concerning fetal death, a five times higher incidence was observed in the group over 40 years old, as compared to the other groups, a statistically significant difference. CONCLUSION: the only difference between the 35 to 39-year-old group and the control group was the cesarean section rate. This allows us to suggest a differentiated prenatal attendance for pregnant women over 40.

PURPOSE: to estimate the sensitivity, specificity and accuracy of patient age, ultrasound result and CA-125 marker variables for the differential diagnosis between malignant and benign ovarian tumors. In addition, to establish a risk of malignancy index (RMI) incorporating these three variables and to estimate its sensitivity, specificity and accuracy for the differential diagnosis. METHODS: one hundred patients with ovarian tumors with surgical indication were included. The age, ultrasonographic findings and CA-125 level variables were evaluated separately and later on together as the RMI. The study was performed based on the evaluation of the sensitivity, specificity and diagnostic accuracy and the use of the measurements: likelihood ratio, odds ratio, and the Student's t test, chi², and logistic regression with univariate and multivariate analysis. RESULTS: for the age variable, sensitivity, specificity and diagnostic accuracy were 58.8, 68.2 and 65.0%, respectively. For ultrasound, 88.2, 77.3 and 81.0%. For CA-125 dosage, the values were 64.7, 74.2 and 71.0%. When the three variables were put together, as the RMI, a sensitivity of 76.5%, a specificity of 87.9% and a diagnostic accuracy of 84.0% were observed. CONCLUSIONS: RMI, made up of the association of patient age, ultrasound results and CA-125 dosage variables is a valuable indicator to distinguish between malignant and benign ovarian tumor, especially in regard to its specificity.
