PURPOSE: To determine the values of amniotic fluid in normal fetuses during the first trimester of pregnancy by three- and bi-dimensional ultrasonography. METHODS: In a prospective longitudinal study, 25 normal fetuses were evaluated from the 8th to the 11th week of gestation. Amniotic fluid volume was measured by endovaginal ultrasonography with the three- and two-dimensional modes. The two-dimensional study consisted of volumetric determination by mathematical calculation based on an ellipsoidal shape (constant 0.52) to obtain the amniotic sac and embryo volumes. In the three-dimensional study, the amniotic fluid volume was determined by the VOCAL technique using 6, 9, 15, and 30 degrees of rotation. The amniotic fluid volume obtained by 6-degree rotations was considered to be the final result. In both modes, amniotic fluid volume was obtained by subtracting the volume of the embryo from the volume of the amniotic sac. Data were analyzed statistically for variance (ANOVA), correlation and regression analysis. The level of significance was set at p < 0.05. RESULTS: The amniotic fluid volume as measured by two-dimensional ultrasonography increased from 5.45 to 39.52 cm³ in the range from the 8th to the 11th week (ANOVA - p < 0.05). There was a correlation between gestational age and amniotic fluid volume (p < 0.001, r² = 88.3%). In the three-dimensional study, the amniotic fluid volume increased from 5.7 to 42.9 cm³ in the range from the 8th to the 11th week (ANOVA - p < 0.05), and again a correlation between gestational age and amniotic fluid volume (p < 0.001, r² = 98.1%) was observed. CONCLUSION: an increase in amniotic fluid volume occurs during the first trimester of pregnancy, as determined by the two- and three-dimensional modes. In addition, we have demonstrated that the higher the gestational age, the larger the amniotic fluid volume.

PURPOSE: To assess the presence of estrogen receptor gene polymorphisms HaeIII and MspI as well as clinical factors, and their possible associations with high mammographic density in post-menopausal women. METHODS: One hundred and fifteen post-menopausal women, not in use of hormonal therapy and without clinical or mammographic lesions were evaluated. Three independent observers have determined the mammographic density pattern based on the ACR-BIRADS® 2003 (two subjective and one objective evaluations - Adobe Photoshop 7.0 software). Oral swabs (Cytobrush) were obtained to extract DNA and the polymerase chain reaction - restriction fragment length polymorphism) was performed to assess the presence of polymorphisms in intron 1 and exon 1 from estrogen receptor gene (HaeIII and MspI). RESULTS: The HaeIII polymorphism was found in 43 (37.4%) of the 115 women, while MspI was found in 96 (83.5%) of them. There was a good agreement among determinations of the three observers with regard to mammographic density. Thirty-four (29.6%) women had dense breasts and eighty-one (70.4%) had non-dense breasts. CONCLUSION: The estrogen receptor gene polymorphism Haelll showed no association with mammographic density (Fisher = 0.712), while the association between estrogen receptor gene polymorphism Mspl and mammographic density was near significance (Fisher = 0.098). The associations among age, parity and body mass index revealed statistical significance.

Uterine myomas are common benign tumors of the female genital tract. The expression of growth factor signal transduction cascade components including the protooncogenes c-myc, c-fos, and c-jun seem to be involved in the development of myomas. PURPOSE: To compare the gene (mRNA) and protein expression of the protooncogenes c-fos, c-myc, and c-jun in human normal myometrium and leiomyoma. METHOD: A case-control study was performed. Samples were collected from 12 patients submitted to hysterectomy at the Hospital de Clínicas at Porto Alegre. The expression of the specific mRNA for c-myc, c-fos, c-jun, and beta-microglobulin was assessed through the RT-PCR technique, using specific primers to each gene. The protein expression of these protooncogenes was evaluated through the Western blot technique with specific antibodies. RESULTS: No statistically significant difference was observed in the gene expression for these protooncogenes between normal myometrium and leiomyoma (c-myc: 0,87 ± 0,08 vs 0,87 ± 0,08, p = 0,952; c-fos: 1,10 ± 0,17 vs 1,01 ± 0,11, p = 0,21; c-jun: 1,03 ± 0,12 vs 0,96 ± 0,09, p = 0,168, respectively). No statiscally significant difference was observed for the protein expression of these protooncogenes between normal myometrium and leiomyoma (c-myc: 1,36 ± 0,48 vs 1,53 ± 0,29, p = 0,569; c-fos: 8,85 ± 5,5 vs 6,56 ± 4,22, p = 0,434; e c-jun: 6,47 ± 3,04 vs 5,42 ± 2,03, p = 0,266, respectively). CONCLUSION: No difference was observed in the gene expression (transcription) nor in the protein expression (translation) of the protooncogenes c-myc, c-fos, and c-jun between leiomyoma and myometrium.

PURPOSE: To analyze gestation evolution and deliveries after myoma treatment by embolization of the uterine arteries. METHODS: In the initial evaluation, 112 patients submitted to embolization of uterine arteries were included for treatment of myoma. From those, only nine wanted to be submitted to conservative treatment in order to keep their reproductive capacity. This procedure was indicated to the nine patients, since they were not susceptible to a conservative surgical treatment. They were submitted to embolization of the uterine arteries with particles of polyvinyl alcohol or embospheres with diameters ranging from 500 to 700 µm, and they have evolved without intercurrence. RESULTS: During the follow-up of these patients, there was a good clinical response with significant reduction in the uterus and myoma volumes. Four of them got pregnant, two had an early abortion and two evolved normally till the end of gestation with a term delivery. One of these had twins. CONCLUSION: Embolization of the uterine arteries is an option for the treatment of uterine myoma, and presents good clinical and anatomical results, allowing patients to preserve their reproductive capacity.

PURPOSE: To verify the existence of association between sub-fertility or infertility and concurrent celiac disease in women attended at a reproductive disorders out-patient clinic of a general hospital. METHODS: This was a case-control study in which a group of 200 women with difficulty in conceiving was compared with a control group with 400 women who were treated at the same hospital for various reasons, but not for fertility problems. Both groups were submitted to the anti-endomysium antibody protocol using the indirect immunofluorescence method. Whenever positive, the diagnosis was further confirmed by endoscopic duodenal biopsy and histopathological exams. RESULTS: Anti-endomysium testing resulted positive in three patients (1.5%) within the group of women with difficulty in conceiving. Diagnosis of celiac disease was subsequently confirmed by histopathological exams of the duodenal mucosa. All the control patients presented negative results in the serological exams. CONCLUSION: Celiac disease was observed only in women with difficulty in conceiving, a relevant fact indicating that this disease may be more common in infertile women. However, new studies with a greater sample size are needed to confirm this possible association.

Cervical pregnancy is a rare condition in which the egg is implanted in the cervical canal causing it to distend as the egg grows. Cervical pregnancy constitutes less than 1% of all ectopic pregnancies. Painless hemorrhage is a habitual clinical characteristic and on physical examination a very vascularized hypertrophic cervix is observed with a tissue surpassing the external orifice. Ultrasonography may be used as a complementary diagnostic tool to show directly the presence of a gestational sac. A successful management of a viable seven-week gestation cervical pregnancy is reported herein. Feticide was performed with a single intraamniotic methotrexate injection (25 mg) guided by transvaginal ultrasonography. Systemic methotrexate in a single dose intramuscular (50 mg/m²) was associated. The conservative management of cervical ectopic pregnancy with methotrexate was effective and safe.

Despite a wide heterogeneity of clinical manifestations related to endometriosis, a high prevalence of the disease is observed in infertile women and in those with chronic pelvic pain. This enigmatic condition has a high socioeconomic impact, and the described data regarding efficacy of the therapeutic approaches are quite conflicting. Thus, the purpose of the present study was to describe the available scientific evidence about the applicable therapeutic modalities and to provide recommendations for the treatment of infertility and the chronic pelvic pain related to endometriosis. Although suppression of ovarian function in patients with minimal or mild endometriosis is not effective in improving fertility, ablation of the lesions associated with adhesiolysis seems to be more effective than exclusive diagnostic laparoscopy. There is no sufficient evidence to determine whether surgical excision in cases of moderate or severe disease would improve the pregnancy rates. In vitro fertilization seems to be an adequate approach, especially in cases of coexistence of infertility factors and/or failure of other treatments. The possibility of using GnRH for 3 to 6 months before in vitro fertilization should be considered. Regarding pain relief, suppression of ovarian function for 3 to 6 months in patients with laparoscopically-confirmed disease reduces the pain associated with endometriosis. All studied medication seem to have similar efficacy, differing only in terms of adverse effects and costs. Ablation of endometriotic lesion reduces the pain associated with endometriosis, being less effective in cases of minimal disease. Exeresis of endometriomas with diameter > 4 cm seems to improve the rate of natural fecundity and the rate for ??? obtained after assisted reproduction procedures, in addition to reducing both pain and recurrence risk. Finally, it is important to emphasize that this subject is much controversial and the recommendations herein described should be revised as randomized controlled clinical trials with adequate casuistic generate more concrete and reliable evidence.
