To evaluate the accuracy of transvaginal ultrasound in the diagnosis of intrauterine lesions, using hysteroscopy as the gold standard.
This was a prospective observational study with 307 patients. All patients underwent hysteroscopy after a previous transvaginal ultrasound to compare the results. The hysteroscopy was performed by experienced examiners, and transvaginal ultrasounds were performed in various public and private services, which is reflective of routine healthcare practices in obstetrics and gynecology. The sensitivity, specificity, and accuracy of the transvaginal ultrasound were calculated using hysteroscopy as the gold standard. The level of agreement between the two exams was calculated using the Kappa test.
Themean age was 56.55±12.3 years. For endometrial polyps, we observed a sensitivity of 39.8%, specificity of 72.7%, accuracy of 52.8%, and Kappa index of 0.11 (p=0.025). For fibroids, the sensitivity was 46.7%, specificity was 95.0%, accuracy was 87.9%, and Kappa index was 0.46 (p<0.001). For endometrial thickening, the sensitivity was 68.7%, specificity was 41.7%, accuracy was 47.6%, and Kappa index was 0.06 (p=0.126). For endometrial atrophy, we found a sensitivity of 6.7%, specificity of 99.3%, accuracy of 90.2%, and Kappa index of 0.10 (p=0.006). For the other findings, the sensitivity was 15.6%, specificity was 99.6%, accuracy was 87.3%, and Kappa index was 0.23 (P<0.001).
Our study demonstrated a low level of accuracy of transvaginal ultrasound for the diagnosis of endometrial lesions, when performed by a non-experienced professional. Thus, it is important to consider the use of hysteroscopy to avoid unnecessary and inappropriate treatments.

PURPOSE: to evaluate the effect of tibolone use on dopplervelocimetric parameters of ophthalmic and retinal arteries. METHODS: clinical, prospective, longitudinal, randomized, placebo-controlled, triple-blind study, in which among 100 menopausal women, 50 have used 2.5 mg of the active principle tibolone (Tib Group) and 50, placebo as a means to form the control-group (Plac Group). In the Tib Group, 44 of the 50 women returned after 84 days to finish the exams, and in the Plac Group, 47. The ophthalmic and retinal arteries were studied to determine the resistance index (RI), the pulsatility index (PI) and the systole/diastole ratio (S/D). Assessments have been done before and 84 days after medication. The t-Student test has been used for the comparison of means between the groups in independent samples, as well as for within-group comparisons in dependent samples. RESULTS: in both groups, the women's characteristics were similar in age, menopause duration, body mass index, arterial blood pressure, deliveries and cardiac rate. The Tib Group presented the following values in the ophthalmic artery: RI(pre)=0.71±0.05, RI(post)0.72±0.08 (p=0.43); PI(pre)=1.29±0.22, PI(post)=1.30±0.25 (p=0.4) and S/D(pre)=3.49±0.77, SD(post)=3.65±0.94 (p=0.32). In the retinal artery, the following values have been found: RI(pre)=0.67±0.09, RI(post)=0.69±0.10 (p=0.7); PI(pre)=1.20±0.29, PI(post)=1.22±0.3 (p=0.2) and SD(pre)=3.29±0.95, SD(post)=3.30±1.07 (p=0.3). Also, the tibolone and control groups did not show any significant difference in regard to the above indexes in the end of the study. CONCLUSIONS: the 2.5 mg dose of tibolone had no effect on the Doppler velocimetry indexes of the ophthalmic and retinal arteries.

PURPOSE: to determine the variation of the number of ovarian follicles during fetal life. METHODS: twelve ovaries donated for research were included in our study, nine from fetuses and three from newborn babies who died in the first hour after being delivered with 39 weeks of pregnancy. Fetal age was confirmed both by the last menstrual period of the woman and by ultrasonography. Ovaries were fixed in formaldehyde, included in paraffin and serially sliced at 7 mm. At every 50 cuts, the obtained material was haematoxilin-eosin stained and evaluated with an optical microscope (400 X). The follicles were counted in ten different regions of the ovarian cortex, each region with an area of 625 mm². The presence of a nucleus was considered the parameter for counting. Follicular density, per 1 mm³ was calculated using the formula Nt=(No x St x t)/do, where Nt is the number of follicles; No is the mean number of follicles in 1 mm²; St is the total number of slices in 1 mm³; t is the slice thickness and do is the nuclei mean diameter. RESULTS: the gestational age of fetuses ranged from 24 to 39 weeks. The number of follicles per 0.25 mm² ranged from 10.9 ± 4.8 in a newborn to 34.7 ± 10.6 in another newborn. Among the fetuses, the least value was obtained in a 36 week-old fetus (11.1 ± 6.2) and the highest in a 28 week-old fetus (25.3 ± 9.6). The total number of slices per ovary ranged from six to 13, corresponding to follicles counted in areas from 15 to 32.5 mm². The total number of follicles ranged from 500,000 at the age of 22 weeks to > 1,000,000 at the age of 39 weeks. CONCLUSIONS: our results demonstrate different (increasing) densities of ovarian follicles along the gestational period, providing more knowledge about this still not well-known subject.

PURPOSE: to identify the incidence and associated factors of surgical scar endometriosis. METHODS: a retrospective cohort observational study performed from the medical records of female patients attended at the Clinical Hospital of Univesidade Federal de Minas Gerais (UFMG) with histopathological diagnosis of scar endometriosis from May 1978 to December 2003. RESULTS: a total of 72 patients were included in the study. The incidence of scar endometriosis after cesarean section was significantly higher than after episiotomy (0.2% and 0.06%, respectively; p<0.00001) with relative risk of 3.3. The women’s age, when diagnosed, ranged from 16 to 48 years old, (mean=30.8 years old). The scar location varied according to the previous surgery: 46 scars after cesarean sections, one after hysterectomy and one after abdominal surgery (48 lesions in the abdominal wall); 19 scars after episiotomy, one because of relapse and two after pelvic floor surgeries (22 pelvic wounds); two women had not been submitted to previous gynecological surgery (one umbilical endometrioma and one lesion in the posterior vaginal wall). Pain was the most frequent symptom (80%), followed by a node (79%) and, in more than 40%, the pain and the node suffered modification with menstruation. Other less frequent complaints were: dyspareunia, secondary infertility, pelvic pain, dysmenorrhoea, scar secretion, menorrhagia pain when evacuating. The mean time observed between the surgery and the beginning of the symptoms was of 3.7 years. The average size of the endometriomas was 3.07 cm. The diagnosis based on clinic evaluation was correct in 71% of the cases. The choice of treatment in all the cases was the surgical excision. In only one incident there was relapse and new intervention. CONCLUSIONS: scar endometriosis is a rare situation originated, in most cases, after obstetrical surgical procedure, with higher risk after cesarean section. It is a highly suggestive clinical condition, with a rare necessity of complementary diagnostic procedures, and the best treatment choice is the surgical excision.

PURPOSE: to evaluate the vascular blood flow of the central retinal arteries using dopplervelocimetry in the different phases of the ovulatory menstrual cycle. METHODS: we performed an observational, longitudinal and prospective study evaluating 34 healthy and ovulatory women. All women were submitted to Doppler scan of the eye to evaluate the vascular resistance of the central retinal arteries, either lying down or on a seated position, during four phases of the menstrual cycle. Confirmation of ovulation was performed by measuring serum progesterone during the luteal phase. We analyzed the pulsatility and resistance index and the maximum, minimum and mean velocity. RESULTS: mean age was 29.7 years. No differences were observed between the indexes obtained in both eyes, therefore a mean index was used for comparisons. As the comparison between the positions used for the exams showed a higher PI for the seated position, the analyses were performed separately. The pulsatility index in the lying position was different among the different phases of the menstrual cycle. The arterial resistance was significantly lower during the intermediate follicular and the periovulatory phases, as compared to the early follicular and luteal phases. When the comparison was performed with the patient in the seated position, no differences were observed. CONCLUSIONS: Our results demonstrate a reduction in the vascular resistance of the cerebral microcirculation and a posterior reversal, as shown by changes in the PI.

PURPOSE: to identify the relationship between serum levels of leptin and the levels of estradiol and follicle-stimulating hormone (FSH) in women with pituitary suppression and to evaluate its possible interference on the reproductive axis. METHODS: a total of 64 patients submitted to controlled ovarian hyperstimulation with recombinant FSH for assisted reproduction, due to a male or tubal factor, and 20 patients using estradiol valerate, for endometrial preparation in order to be submitted to oocyte donation treatment were studied. All patients used GnRH analogues before starting treatment in order to avoid premature LH surge. Data were analyzed statistically by the chi2 test, Student's t-test and the Pearson correlation test, when appropriate, with the level of significance set at p<0,05. RESULTS: it was observed that leptin levels correlated with body mass index (BMI) even though they had not influenced growth rate of these hormones. A positive correlation was observed between estradiol and leptin levels in both groups, as leptin levels increased from 10.42 to 15.68 ng/mL in the FSH group and from 11.09 to 14.5 ng/mL in the estradiol group, following estradiol increase. The growth rate of leptin was higher in women with higher estradiol levels, i.e., who had induced cycles with recombinant FSH, than in those who received estradiol valerate (159.60±58.01 and 136.73±34.17, respectively). CONCLOSION: we may state that leptin correlated with BMI and that both FSH and estradiol do interfere in the regulation of leptin production in women.

OBJECTIVE: to observe if there is any alteration in the Dopplervelocimetry of the uterine arteries of nursing and not nursing women after the insertion of the copper T 380 intrauterine device (IUD). METHODS: prospective, analytical, self-paired clinical assay, with 100 patients in whom we evaluated the color doppler flow: resistance index (RI), pulsative index (PI) and systole/diastole (SD) ratio. Nursing and not nursing women were assessed before IUD insertion as well as 30 days (one cycle) and 90 days (three cycles) after the insertion. RESULTS: the values obtained in the uterine arteries before insertion were: RI: 0.9, PI: 2.4, and SD ratio: 10.0. The values 30 days after insertion were: RI: 0.9, PI: 2.5 and SD ratio: 10.7. After three cycles we found a value of 0.9 for RI, 2.5 for PI and 10.7 for SD ratio. The comparison of the results before and after the IUD insertion showed a p value of 0.51 for RI, of 0.37 for PI and of 0.51 for SD ratio, demonstrating that after the insertion of the IUD, there were no significant changes in Dopplervelocimetry. Also, there were not significant differences between nursing and not nursing women, concerning these parameters. CONCLUSIONS: the use of copper T 380 IUD has no effect on the Doppler indices of the uterine arteries of both nursing and not nursing women.

OBJECTIVE: to evaluate the existence of intra and intercytophathologists disagreement in the analysis of cervical slides previously diagnosed as atypical skin cells with undetermined significance (ASCUS), and the degree of this disagreement. METHODS: a transversal study of 50 cervical slides of Pap smears previously diagnosed as ASCUS, collected in November 2000 in Contagem town. They were analyzed and classified by four cytopathologists according to the first Bethesda system review of 1991 (normal, atrophic alteration, inflammatory alteration, suggestive of LoSIL, suggestive of HiSIL, suggestive of invasive carcinoma and others). After the first analysis, the slides were renumbered in a random order and sent to the same cytophathologists for a new exam. The Kappa test and the weighted Kappa were used in the analysis of the results. RESULTS: there was a high degree of disagreement between the different analyses of the same cytopathologist, varying from 7.8 to 74.4% according to the Kappa test. When a weight of 20% was settled for each degree of disagreement, these values increased from 16.1% for the cytopathologist A to 81.08% for the cytopathologist B. Concerning the comparative analyses made by different examiners the Kappa test values obtained varied from 50.6% to 63.4% in the normal and weighted versions, respectively. CONCLUSIONS: this study confirms the existence of subjectivity in the analysis of the ASCUS category and imprecision in the analysis criteria by the same examiner.
