PURPOSE: to describe to emotional process experienced with termination of pregnancy after the diagnosis of lethal fetal malformation. METHODS: thirty-five pregnant women who underwent termination of pregnancy for lethal fetal anomaly after judicial permission were interviewed. The most frequent fetal malformation was anencephaly (71.5%). The patients were submitted to an open interview as soon as the diagnosis of fetal malformation was confirmed, allowing them to express their feelings and stimulating them to think about asking for termination of pregnancy. The mean time spent until the judicial agreement was 16.6 days. The women who requested and were submitted to the procedure of abortion were invited to return for psychological evaluation after 30-60 days. At this moment, a semi-structured interview was performed to find the emotional aspects and feelings that existed. RESULTS: thirty-five patients were interviewed. The decision-making feelings about termination of pregnancy were negative for 60%, 51.4% declared that they had no doubts about the assumed decision and 65.7% declared that their own opinion was more important for decision than anyone else's. Most of the women (89%) affirmed to remember the facts about the procedure that they experienced, 91% affirmed that they would have the same attitude in the case of another similar situation in the future and 60% declared that they would advise someone to opt for termination of pregnancy if asked about the same situation. CONCLUSIONS: the anguish experienced showed that the process of thinking is very important for the decision-making process and posterior satisfaction with the assumed posture. The psychological follow-up allows to review the moral and cultural values in order to help the decision-making process with the aim of minimizing the suffering.

PURPOSE: to characterize postmenopausal endometrial polyps and to determine risk for concomitant premalignant and malignant pathology. METHODS: a retrospective study including 82 postmenopausal women with a histological diagnosis of endometrial polyps who underwent hysteroscopic polypectomy, after a diagnosis of endometrial thickening made by transvaginal ultrasound, was performed. Medical reports provided clinical and gynecological history, data related to the operative hysteroscopy and definitive histological findings. RESULTS: among the 82 patients who underwent hysteroscopic polypectomy, 10.9% were receiving some type of hormonal therapy. Twenty-eight women (34.1%) reported abnormal vaginal bleeding. Single polyp was encountered in 56 women (68.3%), two polyps were found in 19 cases (23.2%) and in 7 cases (3.6%), three or more polyps were found. The definitive histopathologic analysis revealed 63 (76.8%) benign polyps, 17 (20.8%) hyperplastic polyps (10 cases 12.2% - of simple endometrial hyperplasia without cytologic atypia and 7 cases 8.6% - of complex endometrial hyperplasia without cytologic atypia). Two polyps (2.4%) were diagnosed as harboring neoplasia. For the statistical analysis we employed chi2 test improved by Yates. The authors correlated the polyps' histology with the occurrence of abnormal vaginal bleeding (p=0.0056), number of endometrial polyps (p=0.921) and time after menopause (p=0.720). CONCLUSIONS: endometrial polyps are commonly found entities in postmenopausal women, related with low frequency to endometrial hyperplasia or carcinomas and only histological evaluation seems to allow the exclusion of premalignant and malignant pathology.

PURPOSE: to verify the coverage and factors associated with Papanicolaou (Pap) testing in Londrina (PR), Brazil. METHODS: this is a cross-sectional study, carried out in 2004, in microareas of five Basic Health Units (BHU) of Londrina. One or two microareas from each BHU were selected and a list of all women aged 20-59 years resident in these places, was made through search in the Basic Attention Information System, the women being then visited and interviewed. Those with a Pap test in the last three years were considered as having an updated examination, and the remaining as delayed. The association of some factors with the examination situation was investigated. Data analysis was performed using Epi-Info 6.04d. RESULTS: Pap smear coverage among the 513 participants of the study was 80.7%, ranging from 71.5% to 88.4%. Delay in taking the test was higher (p<0.05) among women who worked only at home (22.4% as compared with 14.3% among those who worked outside), and among those who belonged to D/E social classes (24.9%) as compared to C (17.5%) and A/B (8.3%) classes. The proportion who ignored the next test date was higher (p<0.01) among those who had the last Papanicolaou testing at a BHU (14.7%), as compared to those who had been attended privately or by a health insurance company (5.8%). CONCLUSION: the coverage of Pap smear in the studied areas can be considered satisfactory, although there is a need of improving compliance with Pap test, mainly among women who are the poorest and who work only at home.

PURPOSE: to build a curve of fundal height according to gestational age among low-risk pregnant women and to compare it with the official standards used in Brazil. METHODS: a prospective observational study was carried out. A sample of 227 low-risk pregnant women with gestational age from 13 to 39 weeks was followed-up in the prenatal care sector of two public health services from João Pessoa, PB. Women with a known gestational age, a single live fetus, without malformation, with no known maternal-fetal pathological condition that could possibly affect fetal growth, with a normal body weight, and non-smokers were included in the study. Their fundal height was measured in a standard way, after a previous ultrasound done to confirm the gestational age. The same investigator performed 1206 measurements and each woman had a mean of 5.3 measurements. Statistical tests were performed with a significance level of 5%. Tables and graphs of fundal height were built according to the gestational age with the 10th, 50th and 90th percentiles. RESULTS: the values of percentiles 10, 50 and 90 of fundal height in each gestational age allowed the construction of a pattern curve of fundal height by gestational age among low-risk pregnant women. A clear visual difference was observed between this new and the official fundal height curve. Statistical analyses showed significant differences between them from the 19th week on. CONCLUSION: the results suggest different normal fundal height and fetal growth patterns among low-risk pregnant women on prenatal assistance compared to the used standard curve, thus with different performances when used for diagnosing fetal growth deviations. Future studies should validate the current fundal height curve by gestational age in order to possibly use it as a reference pattern.

PURPOSE: to evaluate the rate of chemically diagnosed pregnancy (serum beta-HCG>25 mIU/mL levels obtained fourteen days after the embryonic transfer) clinically diagnosed pregnancy (gestational sac visualized by ultrasound four to six weeks after the embryonic transfer) and miscarriage rates in women submitted in vitro fertilization to (IVF) and intracytoplasmic sperm injection (ICSI) in a tertiary center of assisted reproduction and to correlate these rates with age. METHODS: retrospective transverse study with analysis of 1016 cycles of controlled ovarian hyperstimulation of 932 infertile women with indication of IVF (370 cycles) or ICSI (646 cycles). The patients' age ranged from 22 to 46 years. All women with age over 35 years included in the study had FSH<15 IU/L. The studied cycles were divided into two groups: the first including the cycles referring to women of 22 to 30 years and the second group, to those of 31 to 46 years. The studied variables were: pregnancy (chemical or clinical) and miscarriage rates. The chi2 test was used to compare these rates between the groups. RESULTS: the total pregnancy rate was 36.42%, with a significant reduction starting at 30 years (p=0.0001). From 22 to 30 years (303 cycles) the pregnancy rate was 45.4%, while in the range from 31 to 46 years (713 cycles), it was 25.1%. The miscarriage rates were, 10.2 11,6%, respectively (p=0.6854). CONCLUSION: although the miscarriage rates did not differ between the groups, a decrease in the pregnancy rate of infertile women submitted to IVF or ICSI was observed after the age of 30 years. Thus, we recommend the gynecologists not to postpone the investigation and the referral for treatment of infertility.

PURPOSE: to determine the intraobserver and interobserver reproducibility of endometrial volume measurements using the VOCAL®-imaging program (Virtual Organ Computer-aided AnaLysis). METHODS: one three-dimensional (3-D) ultrasound dataset of the endometrium was obtained from each of five infertile women with different endometrial volumes. For each 3-D dataset, the endometrial volume was calculated by two different observers using the manual mode in four different rotational steps (30º, 15º, 9º and 6º). Ten measurements were obtained with each method and observer from each 3-D dataset. We have used one-way ANOVA and the Tukey post-test to verify the differences among means and the intraclass correlation coefficient to test reliability. RESULTS: rotational methods employing a rotation step of 30º were associated with lower endometrial volume readings in 3 of the 5 patients. There were no significant differences between the means obtained by the 15º, 9º or 6º step rotation. No significant difference was found between the means obtained by the two different observers. The intraclass correlation coefficients were significantly lower with 30º (all under 0.984) than with the other step rotations (all above 0.996). CONCLUSIONS: the use of a rotational step of 15º or less provides reliable readings of endometrial volume: there were no significant differences between the means calculated by the two observers, associated with highintraclass correlation coefficient (>0.996). We recommend the 15º step rotation because it is quicker to be performed than 6º and 9º.

PURPOSE: to evaluate the influence of abstinence period on seminal characteristics in infertile men and to establish a better seminal quality after pooling the samples. METHODS: a retrospective study was performed on 88 oligozoospermic (n=25), asthenozoospermic (n=43), and oligoasthenozoospermic (n=20) men whose partners underwent intrauterine insemination between September 2002 and December 2004. We excluded men with a normal semen analysis or women with abnormalities suggestive of infertility. Each man produced two semen samples in a short period of time (30 min to 1 h). We evaluated semen volume, total motile sperm count and percentage sperm motility. Comparisons were made between the first and second semen samples. After pooling the samples, we compared the total motile sperm count between the first sample and the pooled samples. Statistical evaluation was performed by Student's t test and the chi2 test. RESULTS: in oligozoospermic men, there were no differences in the semen characteristics between the first and the second seminal samples (p>0.05). The total motile sperm count increased significantly in the second sample in comparison to the first sample in asthenozoospermic (42.4±6.8 vs 51.5±7.2x10(6) sperm/mL) and oligoasthenozoospermic men (11.1±7.4 vs 14.35±7.2x10(6) sperm/mL (p<0.05). The pool of two ejaculates increased the total motile sperm count in comparison to the first sample (p<0.05) in oligozoospermic, asthenozoospermic and oligoasthenozoospermic men by 110.5, 110.3 and 136.03%, respectively. CONCLUSIONS: a short period of abstinence is associated with higher sperm motility in infertile men. The pool of two semen samples is a way to increase the total motile sperm count in this group of patients whose wives want to undergo an intrauterine insemination instead of in vitro fertilization.
