PURPOSE: To evaluate the pregnancy rate in intrauterine insemination (IUI), and to determine possible prognostic factors of successful pregnancy. METHODS: A retrospective study of IUI cycles performed in the Reproductive Medicine Unit of Vila Nova de Gaia Hospital, between January 2007 and July 2010. The IUI cycles were preceded by ovarian stimulation and monitored by vaginal ultrasound. Clinical pregnancy rates were analyzed according to the woman’s age, type and duration of infertility, spermatozoa parameters assessed in the spermogram, number of mature follicles and the drug used for ovarian stimulation. Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS17), with the level of significance set at p<0.05. RESULTS: The study comprised 139 couples who underwent 220 IUI cycles. The absolute pregnancy rate per cycle was 18.6%. Of the 41 clinical pregnancies, 5 were twin pregnancies (12.1%). The pregnancy rate was higher at ages <30 years (28.5 vs 15.7%; p=0.024), duration of infertility <3 years (23.8 vs 13.9%; p=0.05), normal sperm motility (23.2 vs 10.3%; p=0.01) and with two follicles at the time of insemination (27.7 vs 14.2% for monofollicular growth; p=0.030). The pregnancy rates obtained with clomiphene citrate, gonadotropins and combined clomiphene citrate/gonadotropin were 13.0, 26.1 and 28.6%, respectively, with a statistically significant difference in clinical pregnancy rate between clomiphene citrate and gonadotropin. CONCLUSIONS: IUI remains a natural starting point for conveniently selected couples with infertility. Younger age and normal sperm motility are good prognostic factors. Gonadotrophin stimulation seems to be an important tool for improving the pregnancy rate of IUI.

PURPOSE: To study if rheumatoid arthritis (RA) is influenced by age at menarche, number of pregnancies and reproductive life span. METHODS: This was a cross-sectional and retrospective study of medical records of 247 RA patients. We collected data on menarche, menopause, number of pregnancies, autoantibodies, serositis, rheumatoid nodules, and functional index of Steinbrocker. Association studies were done using the Student t and Mann-Whitney tests and correlation was determined by the Pearsonand Spearman tests. The level of significance adopted was 5%. RESULTS: The mean age at diagnosis of RA was 43.2±14.1 years, the median age at menarche was 13 years and the median number of pregnancies was 3. Rheumatoid factor was present in 63.9% of the patients, 20% had antinuclear factor, 8.8% rheumatoid nodules, 2.8% had pleural effusion, and 2.4% had pericarditis. The Steinbrocker functional index showed that 45.6% had a score of 1, 40.8% a score of 2, 3 score of 9.1, and 4.3% a score of 4. We found an inverse correlation between the number of pregnancies and age at onset of RA (p CONCLUSION: A precocious menarche and brief reproductive life indicate a poor prognosis regarding pleurisy. A larger number of pregnancies and late menopause show a protective effect, delaying the onset of the disease.

The uterine cervix invasive carcinoma represents a major public health problem, mainly in the developing countries. Its treatment, based on radical hysterectomy, radiotherapy and/or chemotherapy presents a considerable morbidity. Prognostic markers should be taken into consideration in the therapeutic planning, so that the results would be optimized, complications reduced, and patients' survival prolonged. Accepted prognostic markers are: stage, tumoral size, histological type, degree of differentiation, lymphovascular invasion, depth of the stromal invasion, presence of lymph nodal metastases, and surgical margins involvement. This study aims at making a literature review concerning the use of theses markers in the therapeutic planning of women with uterine cervix invasive carcinoma. The treatment based on these markers may present better results, with lower ratio of complications and an improvement in the patients' survival.

PURPOSE: to evaluate the patient's age as an outcome predictor in an in vitro fertilization (IVF) program. METHODS: transversal study, which has included 302 women with ages varying from 24 to 46 years old, submitted to IVF, from May 2005 to July 2007. The patients were divided in three groups, according to their age: G<35 (n=161), G 36-39 (n=89) e G>40 (n=52). The number of collected oocytes, the fertilization rates, the number of transferred embryos, the embryonary quality and the pregnancy rate were evaluated. Statistical analysis was realized through Kruskal-Wallis variance analysis and χ2 test. RESULTS: in the G<35 group, an average of 8.8 oocytes by patient was obtained; in the G 36-49 group, 7.4; and in the G>40 group, 1.6. The number of oocytes obtained in G>40 group was significantly lower than in the other two groups (p<0.001).The fertilization rate was similar in the three groups, 61.4, 65.8 e 64.6% (p=0.2288), respectively. The percentage of good quality embryos was not statistically different among the three groups either, with rates of 57.4, 63.2 and 56.0% (p=0.2254), respectively. The average number of transferred embryos in each group was 3.1 (G<35), 2.8 (G 36-39) and 1.5 (G>40), respectively, with statistically significant decrease in the G>40 group (p<0.001). Concerning pregnancy rates, the G>40 group has presented a rate of 9.6%, a result which is significantly lower (p=0.0330) than the one presented by the G<35 and G 36-39 groups (26.1 e 27.0%, respectively), with no significant difference between themselves. CONCLUSIONS: though the embryonary quality is not different among women from different age groups, the number of collected oocytes, the number of transferred embryos and the pregnancy rate indicate that the women's age is an important predictive factor of success for the techniques of assisted reproduction and should be taken into consideration when this kind of treatment is proposed to women over 40.

PURPOSE: the objective of this study was to evaluate the clinical, pathological and molecular characteristics in very young women and postmenopausal women with breast cancer. METHODS: we selected 106 cases of breast cancer of very young women (<35 years) and 130 cases of postmenopausal women. We evaluated clinical characteristics of patients (age at diagnosis, ethnic group, family history of breast cancer, staging, presence of distant metastases, overall and disease-free survival), pathological characteristics of tumors (tumor size, histological type and grade, axillary lymph nodes status) and expression of molecular markers (hormone receptors, HER2, p53, p63, cytokeratins 5 and 14, and EGFR), using immunohistochemistry and tissue microarray. RESULTS: when comparing clinicopathologic variables between the age groups, younger women demonstrated greater frequency of nulliparity (p=0.03), larger tumors (p<0.000), higher stage disease (p=0.01), lymph node positivity (p=0.001), and higher grade tumors (p=0.004). Most of the young patients received chemotherapy (90.8%) and radiotherapy (85.2%) and less tamoxifen therapy (31.5%) comparing with postmenopausal women. Lower estrogen receptor positivity 49.1% (p=0.01) and higher HER2 overexpression 28.7% (p=0.03) were observed in young women. In 32 young patients (29.6%) and in 20% of the posmenopausal women, the breast carcinomas were of the triple-negative phenotype (p=0.034). In 16 young women (50%) and in 10 postmenopausal women (7.7%), the tumors expressed positivity for cytokeratin 5 and/or 14, basal phenotype (p=0.064). Systemic metastases were detected in 55.3% of the young women and in 39.2% of the postmenopausal women. Breast cancer overall survival and disease-free survival in five years were, respectively, 63 and 39% for young women and 75 and 67% for postmenopausal women. CONCLUSIONS: breast cancer arising in very young women showed negative clinicobiological characteristics and more aggressive tumors.

PURPOSE: to analyze the expression of matrix metalloproteinase-9 (MMP-9) and of vascular endothelial growth factor (EVGF) in a group of patients with primary breast cancer, and correlate them to one another and with other prognostic indicators. METHODS: transversal study that has analyzed the expression of MMP-9 and of VEGF in 88 consecutive cases of primary breast tumors. The samples were obtained from patients with primary breast cancer, submitted to surgical treatment in the Clinical Hospital of Porto Alegre of the Universidade Federal do Rio Grande do Sul, from January 2000 to December 2004. An immunohistochemical technique has been applied, using the avidin-biotin-peroxidase complex to evaluate the antigen immunoreactions in the tumors. The qualitative expression of proteins has been assessed through the observation of the brownish stain intensity of antibodies in the cytoplasm of malignant cells, when at least one of the tumoral cells presented clear and unequivocal staining with each of those markers. To determine the qualitative score (0=absent, 1=weak, 2=average and 3=strong), the stronger cytoplasmatic staining intensity on the glass slide has been taken into consideration, independently of the stained cells. The quantitative expression was determined by the average percentage of stained cells, observed in at least ten microscopic fields. The MMP-9 and VEGF final quantification expression has been done by the application of the HSCORE=Σ[(I+1)]xPC, where I and PC represent the staining intensity and the percentage of stained cells, respectively. RESULTS: MMP-9 and VEGF presented a significant correlation in the tumors studied. The final expression has shown a median score of 180 and 190, respectively. When MMP-9 and VEGF expression were compared with the variables "age", "tumoral diameter", "histological type", "histological grade", "axillary lymph node" and "vascular invasion", it was impossible to find any significant correlation. Compared to one another, MMP-0 and VEGF have presented a positive correlation (rho=0.23; p=0.03). The axillary lymph node positivity has presented a positive correlation with the larger tumoral diameter (2.7±1.1 cm; p<0.01) and with the presence of vascular invasion (84.1%; p<0.01). CONCLUSIONS: The present results do not show correlation between the MMP-9 and VEGF with the selected prognostic indicators, but shown a significant correlation between one another.

PURPOSE: to describe the clinical and laboratorial profile of HELLP syndrome patients admitted at an Obstetric Intensive Care Unit (ICU) and included in a randomized clinical trial to evaluate the efficacy of dexamethasone in this clinical setting. METHODS: the present study is a secondary analysis of a randomized clinical trial design to evaluate the efficacy of dexamethasone in patients with HELLP syndrome. This sample of patients was composed of patients in the puerperium, with the diagnosis of HELLP syndrome (diagnosis made before or after delivery) who were not chronic corticosteroid users and not carriers of any chronic disease which could modify HELLP syndrome's laboratorial parameters. Patients who were too critical or whose condition did not allow them to consent to participate were not included. Data were extracted from the records used in the randomized clinical trial. Age, parity, gestational age at admission and delivery, time of diagnosis (before or after delivery), HELLP syndrome classification (partial or complete), arterial blood pressure, and diuresis at admission were considered for analysis. Among laboratorial findings, hemoglobin, platelet count, liver enzymes, LDH, and serum bilirubin were analyzed. Complications presented by the patients were also analyzed as well as need of blood transfusions and duration of hospitalization. Analysis was made by the Epi-Info 3.3.2 program. RESULTS: one hundred and five patients were analyzed. Age varied from 14 to 49 years (means of 26.7). Regarding parity, 56 patients (53.8%) were primiparas. Analyzing the timing of the diagnosis, 47 patients (45.2%) had the diagnosis before delivery. The mean gestational age in these patients was 32.4 weeks. Hemorrhagic manifestations were observed in 36 patients (34.3%), oliguria was present in 49 patients (46.7%) and criteria for acute renal failure were seen in 21 (20%) of the cases. Hemotransfusions were necessary in 35 (33.3%) patients. Seven patients (6.7%) had pulmonary edema and four patients died, corresponding to 3.8% of the cases. The mean time from diagnosis of HELLP syndrome to discharge or death was 10.3 days, varying from 1 to 33 days. CONCLUSIONS: HELLP syndrome is an ominous diagnosis, which implicates in elevated maternal morbimortality. Among complications, oliguria and hemorrhagic manifestations were the most common findings and hemotransfusions were frequently required. Lethality reached 3.8%.
