PURPOSE: to determine the prevalence of high-grade squamous intraepithelial lesions (HSIL) and cancer in women with cytological diagnosis of persistent ASCUS (atypical squamous cells of undetermined significance) for 6 months in the last 7 years. We also assessed if age could be a predictive factor for presence of HSIL/cancer in this group. METHODS: we included 215 cases of non-pregnant and HIV-seronegative women with cytological diagnosis of persistent ASCUS (unespecific) with at least 6 months of interval between smears. This cytological diagnosis was compared to histological diagnosis obtained by biopsy (large loop excision of the transformation zone) or cone biopsies, and considered negative when colposcopy was satisfactory without lesions or, when unsatisfactory, no lesion was detected after at least one cytological and colposcopic follow-up. RESULTS: among the 215 cases, 49.3% had negative results (CI 95%: 42.6-55.9). The prevalence of histological confirmed low-grade squamous intraepithelial lesion was 38.6% (CI 95%: 32.1- 45.1) and HSIL was 10.7% (CI 95%: 6.5-14.8). Cases of cancer were found in 1.4% of patients (CI 95%: 0-2.9). We could not find a significant difference between the prevalence of HSIL/cancer according to age group using the cutoff point of 35 years. CONCLUSION: HSIL/cancer prevalence observed in this study has shown the risk of finding this kind of lesions in about 12% of women assisted in our public health system with two cytological diagnosis of ASCUS. A higher probability of HSIL/cancer in the different age groups was not found but this result was limited by our small sample size.

PURPOSE: to evaluate the prevalence of hemoglobin S (HbS) in newborns, through clinical investigation and laboratory data. METHODS: a protocol established the drawing of 10 mL blood from the umbilical cord after its ligature and section, immediately after birth. The samples were kept in a tube with 5% EDTA and then submitted to high-performance liquid chromatography. The study included a clinical record taken from an interview with the mother, her physical and biochemical condition, as well as that of her newborn. Main criteria were newborn's weight, sex, first minute Apgar, and the mother's color. Statistical analysis was based on the Epi-Info 6.0 program and performed by Student's t test, with the level of significance set at p<0.05. RESULTS: from August 2001 to September 2002, 389 umbilical cord blood samples showed HbS in 16 newborn babies (4.1%). Fifteen of these presented sickle-cell traits (HbS) and the other had a diagnostic hypothesis of sickle-cell anemia (HbSS). Hemoglobinopathy prevailed among male babies. No significant difference was observed between newborns with or without HbS regarding averages of weight and Apgar scores; the same occurred regarding the mother's skin color (Caucasians, mulattos and blacks). CONCLUSION: searching for hemoglobin diseases in newborns should be considered because of the possibility of 25% sickle-cell anemia in the offspring of couples with sickle-cell traits. Screening for abnormal hemoglobin is important in the population at risk. Thus, the creation of programs with these aims is recommended to be included in hospital routines.

PURPOSE: to investigate the presence and outcome of uterinevascular malformations (UVAM) after gestational trophoblastic disease (GTD). METHODS: retrospective study of 2764 patients with GTD diagnosed from 1987 to 2004. All patients were followed up annually at the "Santa Casa da Misericórdia" Trophoblastic Disease Center (Rio de Janeiro, RJ, Brazil) with transvaginal ultrasonography (US) and color Doppler imaging. Seven patients had a final diagnosis of UVAM based on ultrasonographic analysis - pulsatility index (PI), resistance index (RI), peak systolic velocity (PSV) - and pelvic magnetic nuclear resonance (MNR) findings. Negative beta-hCG values were of utmost importance to establish differential diagnosis with persistent GTD. RESULTS: the incidence of UVAM after GTD was 0.2% (7/2764). US features of UVAM: PI mean 0.44±0,058 (extremes: 0.38-0.52); RI mean 0.36±0.072 (extremes: 0.29-0.50); PSV mean 64.6±23.99 cm/s (extremes: 37-96). MNR image showed a bulky uterus, myometrial inhomogeneity, serpiginous flow-related signal voids, and prominent parametrial vessels. The most common UVAM clinical presentation was vaginal hemorrhage, present in 52.7% (4/7). Pharmacological management with 150 mg medroxyprogesterone acetate was employed to control bleeding, after hemodynamic stabilization. These patients are still being followed and remain asymptomatic nowadays. Two patients with persistent UVAM became pregnant and had successful outcomes. CONCLUSION: patients with antecedent of GTD presenting transvaginal bleeding and negative beta-hCG may be considered to have UVAM and should be investigated through US with Doppler velocimetry. Conservative management is a valuable option in many of the acquired UVAM after GTD.

PURPOSE: we report a small series of pregnant women who underwent gastric bypass surgery for severe obesity, with a review of the literature on this topic. METHODS: five consecutive cases of pregnancy after gastroplasty between 2001 and 2004 were evaluated, and clinical, laboratory and therapeutic features were considered. Patients were 30 to 34 years old and all had been submitted to gastroplasty by the Capella technique. The outcomes for both the pregnant woman and the fetus were evaluated. A search of the English language literature was done through MEDLINE and Web of Science databases with the following terms: gastroplasty, gastric bypass surgery, bariatric surgery, and pregnancy. RESULTS: all 5 pregnancies were singleton. No major obstetric complications were observed and there were no premature or lowbirth weight infants. CONCLUSION: our data suggest that pregnancy following gastroplasty is safe for mother and fetus. However, since information about this topic is limited, further investigations are required to establish appropriate recommendations concerning the follow-up of these pregnancies.

PURPOSE: to evaluate the effects of conjugated equine estrogens (CEE) and raloxifene (Ral), alone or combined, on the rat endometrium. METHODS: fifty-six adult rats were ovariectomized and randomly divided into seven groups: GCont (control); GCEE (CEE 50 µg/kg); GCEE/25 (CEE 25 µg/kg); GRal/0.75 (Ral 0.75 mg/kg); GRal/0.4 (Ral 0.4 mg/kg); GCEERal (50/0.75) - (CEE 50 µg/kg + Ral 0.75 mg/kg), and GCEE-Ral (25/0.4) - (CEE 25 µg/kg + Ral 0.4 mg/kg). The drugs were orally administered (gavage) for 21 consecutive days. At the end of the experiment, all animals were anesthetized and sacrificed. Fragments of uterus were removed, fixed in 10% formaldehyde and processed for paraffin inclusion. The histological sections were stained by HE and submitted to histomorphometric evaluation. The following parameters were analyzed: thickness of superficial epithelium and number of endometrial glands/mm² and of blood vessels/mm². The data were evaluated using ANOVA followed by the Turkey-Kramer test. RESULTS: in the GCont and only Ral treatment (GRal/0.75 and GRal/0.4) the endometrium showed signals of atrophy. In the groups treated with only CEE signs of endometrial proliferation were observed, mainly in group GCEE/50. Also, there was endometrial proliferation in the groups that received combined CEE and Ral (Ral GCEE (50/0.75) and GCEE-Ral (25/0.4)), but it was more intensive in the animals treated with isolated estrogen than in those that received combined estrogen and raloxifene. CONCLUSION: raloxifene may partially block the action of estrogen on the castrated adult rat endometrium.

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.

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 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.
