Purpose: to evaluate the effects of tamoxifen (TAM) on plasma levels of estradiol, progesterone, prolactin, luteinizing hormone (LH), follicle-stimulating hormone (FSH) and steroid hormone-binding globulin (SHBG) when given to premenopausal women in the doses of 10 and 20 mg/day for 22 days. Patients and Methods: a randomized double-blind study was performed with 43 premenopausal eumenorrheic women. The patients were divided into three groups: A (N = 15, placebo); B (N = 15, TAM 10 mg/day) and C (N = 13, 20 mg/day). They started taking an oral dose of TAM or placebo on the very first day of the menstrual cycle. Two hormone determinations were performed, both on the 22nd day of the menstrual cycle: the first in the cycle that preceded the use of the drug and the second, in the following cycle, after 22 days of using the medication. We used the Levine and Student tests in order to evaluate the homogeneity of the sample and the variation of the hormone determinations respectively. Results:serum levels of estradiol, progesterone and SHBG increased significantly in groups B and C. In group C, we also observed increase in serum level of FSH (p < 0.0045) and a fall in prolactin level (p < 0.0055). Conclusions: TAM promoted a significant increase in serum concentrations of estradiol, progesterone and SHBG either in the doses of 10 or 20 mg/day. However, significant increase in FSH and decrease in prolactin were obtained only with the dose of 20 mg/day.

Purpose: to evaluate the agreement between the urodynamic and ultrasonography diagnoses of urinary incontinence, as well as to correlate the variables of both examinations. Methodology: three hundred eighty-one patients with urine loss were selected, from the Sectior of Urogynecology and Vaginal Surgery of the Division of Gynecology, Escola Paulista de Medicina - Federal University of São Paulo. All of them were submitted to urodynamic study, according to the standardization of the International Society of Continence, and to ultrasonography of the bladder neck, with a 6 MHz trasvaginal transducer. We analyzed the maximum closing urethral pressure (MCUP) and the etiological diagnosis of the urine loss. In the ultrasonography, the position of the bladder neck was evaluated in relation to the inferior border of the pubic symphysis, and its mobility as well as the diameter of the urethra and bladder neck. The women were categoriaed according to the urodynamic study in to stress urinary incontinence, detrusor instability and mixed urinary incontinence. Results: 1) the bladder neck, at rest was most frequently above the inferior border of the pubic symphysis and, during effort, below or at the height of the bony reference, in the three groups; 2) the mobility of the bladder neck was similar in the groups; 3) there was no significant correlation between MCUP and the diameter of the urethra and of the bladder neck. Conclusion: we deem that ultrasonography of the bladder neck is always a complement to the clinical evaluation and the urodymanic study.

PURPOSE: to analyze breast tissue of postmenopausal women before and after six months of continuous combined estrogen-progestin replacement therapy (0.625 mg conjugated equine estrogens associated with 2.5 mg medroxyprogesterone acetate). METHODS: all patients were evaluated before treatment and considered eligible to receive the drug. The material was obtained from the upper outer left quadrant, through a percutaneous large-core breast biopsy. Epithelial density and nuclear volume on hematoxylin-eosin-stained plates were evaluated for the morphological study. Morphometry was graphically analyzed by optical microscopy (400X) after acquisition of image by a digital image-capturing system (Vidcap 32) and image analysis system (Imagelab 2000 Software®). RESULTS: after six months of estrogen-progestin replacement therapy, there was a significant increase in nuclear volume in late postmenopausal women (103.6 to 138.1 µm³). There was no difference in epithelial density with the treatment (before 0.08 and later 0.10). CONCLUSIONS: estrogen-progestin combined replacement therapy for six months induced an enhacement in nuclear volume of breast epithelial cells, suggesting an increase in their metabolic activity. However, it is important to emphasize that this finding was observed only in late postmenopausal women. The increased nuclear volume could precede other events that confirm the stimulation of cellular proliferation by these hormones.

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 analyze race, parity and presence of the progesterone receptor polymorphism, named PROGINS, as factors related to uterine leiomyoma occurrence in Brazilian women. METHODS: we carried out a case-control study, composed of 122 patients with the diagnosis of uterine fibroid and 125 women without the disease. After recording the clinical data, we collected biological material for DNA extraction, polymerase chain reaction and agarose gel electrophoresis in order to identify the presence of PROGINS polymorphism. Statistical analysis was performed using the non-parametric Mann-Whitney test or the chi2 test, depending on the studied variable. The risk for the occurrence of the disease was calculated by the logistic regression model, providing the odds ratio (OR). The adopted significance level was 5% (p<0.05) and the confidence interval was 95% (95% CI). RESULTS: we observed a higher prevalence of "non-white"women - mulatto and black - (50 vs 22.4%) and nulliparas (23.8 vs 11.2%) in the cases, while the progesterone receptor genotype was more often PROGINS positive - heterozygous or mutant homozygous - among the controls (21.6 vs 10.7%). The OR indicated an elevated risk for leiomyoma related to the "non-white"race (OR=3.46; 95% CI: 2.0-6.0) and the nulliparity (OR=3.30; 95% CI: 1.9-5.6), with reduction in the presence of PROGINS-positive genotypes (OR=0.43; 95% CI: 0.2-0.9). CONCLUSIONS: the "non-white"race and nulliparity were considered risk factors for the occurrence of uterine fibroid in the studied population, while PROGINS polymorphism showed to be a protective factor.

Female lower urinary tract symptoms are nonspecific and a clinical evaluation is required to establish the correct diagnosis. Such evaluation should consist of a structured micturition history or questionnaire, physical examination, micturition diary, pad test, and urodynamic evaluation. Urodynamic investigation was developed as an extension of patient history and physical examination in order to reveal the etiology of the patient's complaints. The goal of the present article is to review clinical and subsidiary diagnosis of urinary incontinence.

PURPOSE: to evaluate the cost of preventive mammographic screening in climacteric women, as compared to the cost of breast cancer treatment in more advanced stages. METHODS: one thousand and fourteen patients attended at the Climacteric outpatient service of the Gynecology Department, Federal University of São Paulo Paulista School of Medicine, were included in the study and submitted to mammographic test. All mammographic test's were analyzed by the same two physicians and classified according to the BI-RADS (Breast Imaging Reporting and Data System American College of Radiology) categories. The detected lesions were submitted to cytological and histological examination. RESULTS: the final diagnostic impression of the 1014 examinations, according to the classification of BI-RADS categories was: 1=261, 2=671, 3=59, 4=22 and 5=1. The invasive procedures were performed through a needle guided by ultrasound or stereotactic examinations: 33 fine-needle aspiration biopsies, 6 core biopsies guided by ultrasound and 20 core biopsies guided by stereotactic examination. Five cancer diagnoses were established. The total cost of this screening based on Brazilian procedure values was R$ 76,593.79 (25,534 dollars). Therefore, the cost of the diagnosis of the five cases of cancer in this screening was R$ 15,318.75 (5,106 dollars) each. However, the average cost per patient screened was R$ 75.53 (25 dollars). CONCLUSIONS: considering that the total treatment cost of only one case of breast cancer in advanced stage including hospital costs, surgery, chemotherapy, radiotherapy and hormonal treatment is similar to the cost of 1,000 mammographic screenings in climacteric women, it may be concluded that the cost of the early cancer diagnosis program is worth it and should be included in the public health program, as a way of lowering the public health expense.
