PURPOSE: to evaluate the characteristics of the menstrual cycle and to identify the occurrence of ovulation in nulliparous young women with sickle cell anemia (SCA). METHODS: we conducted a case-control study including 26 nulliparous women of reproductive age, divided into two groups: "cases", consisting of 13 women with SCA, and "Control" Group, consisting of 13 healthy women with the same interval since menarche. The characteristics of the menstrual cycle were reported by the participants, who were also submitted to measurements of serum progesterone, basal body temperature curves and transabdominal ultrasound in three consecutive cycles (total: 78 cycles) in order to identify the occurrence of ovulation. The results were compared between groups using the nonparametric Mann-Whitney or Kruskal Wallis tests, and the differences were considered significant when p-value < 0.05. RESULTS: no significant difference was found in mean chronological age between the two groups (p = 0.2) in the pattern of the menstrual cycle when duration of flow (p = 0.4) and interval between cycles (p = 0.3) were compared. There was no difference between groups in age at menarche (p = 0.05). Mean hemoglobin value was 8.4 g/dL (± 0.9) in the group of women with SCA and 12.6 g/dL (± 0.8) in the control group (p < 0.01). The frequency of ovulatory cycles was similar for cases (76.9%) and controls (92.3%) (p = 0.5), with a predominance of individuals with three ovulatory cycles in the control group (84.6%) compared to 23.1% in the case group (p = 0.04). CONCLUSION: the findings justify the need for effective guidance for patients with SCA regarding sexual activity, the possibility of pregnancy and the alternatives for contraception.

PURPOSE: to evaluate the effectiveness of uterine fibroid embolization (UFE) in patients with giant fibroids, with regard to both clinical outcomes and size reduction. METHODS: twenty-six patients with a mean age of 36.5 years, carrying symptomatic fibroids with a volume over 1,000 cm³, were referred for UFE. All patients had indication for percutaneous treatment. The procedures were performed under epidural anesthesia and sedation, using an institutional protocol. By unilateral femoral access, selective catheterization of uterine arteries and infusion of calibrated microspheres through microcatheter were carried out. Clinical evaluation was performed by means of regular outpatient gynecology consultation. All patients underwent magnetic resonance imaging (MRI) before the procedure and 15 patients underwent control MRI after 6 months. RESULTS: technical success was 100%. There was no complication related to the procedures. Mean uterine volume of the 15 patients studied was 1,401 cm³ before embolization (min 1,045 cm³, max 2,137 cm³) and 799 cm³ after 6 months (525 cm³ min, max. 1,604 cm³), resulting in a total reduction of 42.9%. Clinical improvement was observed in 25 of 26 patients. One woman with uterine volume of 1,098 cm³ who developed necrosis and partial fibroid expulsion underwent myomectomy. Another patient was submitted to myomectomy six months after the procedure because she wanted to become pregnant, despite partial fibroid size reduction. One patient with a uterine volume of 2,201 cm³ required a second intervention to achieve an adequate angiographic result. No patient underwent hysterectomy. On average, 9.2 microsphere syringes were used per patient. CONCLUSION: embolization of giant uterine fibroids is a feasible procedure with acceptable clinical and radiological outcomes. It can be considered an option for patients who desire to preserve the uterus, and it may serve as adjuvant therapy for high-risk myomectomy.

PURPOSE: to evaluate the impact of body mass index (BMI) on in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes performed at the Human Reproduction Center of Faculdade de Medicina do ABC. METHODS: retrospective data from 488 IVF cycles of 385 patients. Patients were classified into two groups according to BMI: normal weight (18.5-24.9 kg/m²) and overweight/obesity (>25 kg/m²). We evaluated the dose of recombinant follicle stimulating hormone (FSHr), the cancellation rates for ovarian cycle response, and the results of the assisted reproduction laboratory such as number of oocytes, number of good quality embryos, number of embryos transferred, and pregnancy rates, chemical pregnancy rates, miscarriage rate and live birth rate. The t test was used for comparison of quantitative variables between groups, and the χ2 test for comparison between qualitative variables. P values <0.05 were considered significant. RESULTS: considering ovulation induction characteristics, there was no statistically significant difference between groups regarding the FSHr dose administered or the cancellation rates, p=0.47 and p=0.85, respectively. Regarding laboratory findings, the number of oocytes retrieved per cycle was similar for both groups (p=0.09), as also was the number of good quality embryos obtained and transferred (p=0.7 and p=0.6). The pregnancy rate per embryo transfer was 27.6% for the group of normal weight and 29.6% for the overweight/obese group (p=0.76). Miscarriage rates and birth rates were similar for both groups, p=0.54 and p=0.94. CONCLUSION: BMI did not influence IVF/ICSI outcomes evaluated.

PURPOSE: to reassess the adrenal function of patients with PCOS after the introduction of the Rotterdam's criteria. METHODS: descriptive and cross-sectional study including 53 patients 26±5.1 years old. Glucose, glycosylated hemoglobin, lipids, estradiol, progesterone, 17-OHP4, DHEAS, FSH, LH, TSH, PRL, androstenedione, free thyroxine, insulin, total testosterone, SHBG, and free androgen index were measured. Insulin resistance was considered to be present with a homeostatic model assessment index >2.8. The adrenal response to cortrosyn was assessed by the hormonal rise observed at 60 minutes, and by the area under the response curve. RESULTS: biochemical hyperandrogenism was found in 43 of 53 eligible patients (81.1%). Thirty-three women had adrenal hyperandrogenism (62.2%). The weight of these 33 women, aging 25.1±5.0 years, was 74.9±14.9 kg, BMI was 28.8±6.0 and the waist/hip ratio was 0.8±0.1. DHEAS was >6.7 nmol/L in 13 (39.4%) and androstenendione was >8.7 nmol/L in 31 (93.9%). The increments in 17-OHP4, cortisol, A, and progesterone were 163%, 153%, 32%, and 79%, respectively. The homeostatic insulin resistance model was >2.8 in 14 (42.4%). Insulin and estradiol were not correlated with cortisol or androgens. CONCLUSIONS: the use of multiple endocrine parameters showed a high prevalence of biochemical hyperandrogenism in patients with PCOS. Two thirds of the patients had adrenal hyperandrogenism, and estradiol and insulin did not influence adrenal secretion.

PURPOSE: the purpose of this research was to evaluate the morphological aspects and vasculature of the corpus luteum (CL) based on ultrasound parameters during early pregnancy and to assess their relationship with early pregnancy loss. METHODS: this was a prospective cohort study of 90 pregnant patients between 6 and 8 weeks plus 6 days weeks of gestation. We included women at low risk, without acute or chronic systemic disease and with spontaneous conception. Exclusion criteria: use of drugs or smoking, drugs inducing ovulation, history of more than one abortion, no heartbeat visible in the embryo and impossibility of visualization of the corpus luteum. The size, volume, morphological aspects, resistive index, and peak systolic velocity of the corpus luteum were measured by transvaginal sonography. RESULTS: ninety patients were included in the study. Maternal age ranged from 15 to 41 years (mean 28.6±5.8 years). The corpus luteum could be visualized in 87 patients (96.7%), 79 patients had normal pregnancies (90.1%), whereas spontaneous losses occurred in 8 cases (9.9%). In a comparison of the survivors and losses, there was no difference in mean CL diameter (21.8 versus 20.0 mm; p=0.108, Mann-Whitney test), mean CL volume (4.2 versus 3.0 cm³; p=0.076, Mann-Whitney test), mean resistive index (0.55 versus 0,58; p=0.220, Mann-Whitney test), peak systolic velocity (15 versus 15 cm/s; p=0.757, Mann-Whitney test). There was a positive relation between maternal age and resistive index. CONCLUSIONS: no apparent correlation was found between the morphological and vascular aspects of the corpus luteum in early normal pregnancies and first-trimester pregnancy losses.

PURPOSE: to evaluate the effect of administration of three different doses of the zidovudine/lamivudine/ritonavir combination on the liver and kidneys of pregnant rats and their concepts from a morphological and physiological standpoint. METHODS: 40 pregnant EPM-1 Wistar rats were randomly divided into 4 groups: 1 control (Ctrl: drug vehicle control, n=10) and 3 experimental groups: Exp1x, Exp3x and Exp9x. An oral solution of the zidovudine/lamivudine/ritonavir combination was administered to the experimental groups from the day 0 to day 20 of pregnancy: Exp1x=10/5/20 mg/kg; Exp3x=30/15/60 mg/kg; Exp9x=90/45/180 mg/kg. On the 20th pregnancy day the rats were anesthetized and blood was taken directly from the ventricular chambers for further biochemical determinations: aspartate-(AST) and alanine-(ALT) aminotransferases (Calorimetric method), urea nitrogen (BUN) by an enzymatic-kinetic method, and creatinine by a kinetic-calorimetric method. Maternal and fetal liver and kidney samples were taken, fixed in 10% formaldehyde and processed histologically for paraffin embedding. Five µm-thick fragments of maternal and fetal livers and kidneys were stained with hematoxilyn-eosin, being analyzed by light microscopy. To interpret the results, the well-known pattern of normality for livers and kidneys was considered on the basis of the following structures: hepatocytes, portal structure, hepatic veins, renal corpuscles, renal tubules and loop of Henle. Regarding the fetal livers, we also considered the erythrocytes in their different stages of development as well as the megacariocytes. If there was a change in the established staining pattern for liver and kidney structures, changes in nuclear morphology, rupture of some cytoplasmic organelles, and presence of vascular congestion, this was considered to be due to the drug doses. Results were submitted to analysis of variance (ANOVA) and to the Tukey-Kramer multiple comparisons test (p<0.05). RESULTS: no morphological changes were observed in the maternal livers of the Ctrl, Exp1x and Exp3x groups. In the maternal liver of the Exp9x group, hepatocytes showed signs of atrophy and apoptosis (eosinophilic cytoplasm and pycnotic nuclei) and marked sinusoid capillary vasodilation (congestion) was observed. The maternal kidneys of the Ctrl and Exp1x groups were normal, with renal corpuscles, convoluted tubules and typical loops of Henle. In contrast, the Exp3x and Exp9x groups showed vascular congestion and small glomeruli rich in cells containing hyperchromatic nuclei which were more intense in Exp9x. Regarding the fetal organs, no morphological or physiological changes were observed. A significant increase of AST (305.70±55.80, p<0.05) and creatinine (0.50±0.09, p<0.05) was observed in group Exp9x. CONCLUSIONS: our results show that the administration of the zidovudine, lamivudine and ritonavir combination to pregnant rats at high doses caused morphological and physiological changes in the maternal liver and kidneys. On the other hand, there were no changes in fetal organs.

PURPOSE: to evaluate the evolution of adequacy of the care process among pregnant users of the Brazilian Single Health System (SUS, acronym in Portuguese) and to consolidate a methodology for monitoring the prenatal care. METHODS: this is a multiple time series study with auditing of prenatal cards of pregnant women who were attended for prenatal care in a city of the Brazilian Southeast (Juiz de Fora, Minas Gerais) in the initial semesters of 2002 and 2004 (370 and 1,200 cards, respectively) and gave birth using SUS services in term pregnancies (p < 0.05). A three complementary level sequence was respected: utilization of prenatal care (beginning and number of visits) at level 1; utilization of prenatal care and obligatory clinical-obstetric procedures during prenatal visits (assessment of blood pressure (BP), weight, uterine fundal height (FH), gestational age (GA), fetal heart rate (FHR) and fetal presentation) at level 2; and utilization of prenatal care, obligatory clinical-obstetric procedures and basic laboratory tests, according to the Humanization Program of Prenatal Care and Birth (PHPN, acronym in Portuguese) (ABO/Rh, hemoglobin/hematocrit (Hb/Htc), VDRL, glycemia and urinalisys) at level 3. RESULTS: it was confirmed the high prenatal care coverage (99%), the increased mean number of visits per pregnant woman (6.4 versus 7.2%) and the decreased gestational age at the time of the first visit (17.4 versus 15.7 weeks). The proper registration of procedures and exams (exceptions: fetal presentation and blood typing) has significantly increased: BP (77.8 versus 83.9%); weight (75.4 versus 83.5%); FH (72.7 versus 81.3%); GA (58.1 versus 71.5%); FHR (79.5 versus 86.7%); Hb/Htc (14.9 versus 29%), VDRL (11.1 versus 20.7%), glycemia (16.5 versus 29%) and urinalisys (13.8 versus 29.8%). As a result, there was significant (p < 0.001) improvement of the adequacy between 2002 and 2004: 27.6 versus 44.8% (level 1); 7.8 versus 15.4% (level 2); 1.1 versus 4.5% (level 3). This trend was also noted in care provided by the majority of the municipal services/teams. CONCLUSIONS: the persistence of low adequacy, despite good coverage and PHPN implementation, confirmed the need to increase health managers, professionals and users' compliance with the rules and routines of care, including the institutionalization of a monitoring program of prenatal care.
