PURPOSE: to evaluate patients who presented post-hysterectomy vaginal vault prolapse and were treated surgically by abdominal sacropexy (ASP) during the period of 1995-2000 at the São Paulo Hospital (EPM-UNIFESP). METHODS: we studied retrospectively 21 patients with post-hysterectomy vaginal vault prolapse with previous correction of cystocele and rectocele. An analysis was made taking into account the average age of the patients, number of parturitions, weight, body mass index (BMI), time between the appearance of the prolapse and the hysterectomy, duration of surgery, blood loss and recurrences. The patients underwent surgery using the abdominal sacropexy technique with or without the interposition of a synthetic prosthesis between the vaginal wall and the sacrum. RESULTS: of the patients attended in our service, 15 used the ASP technique and in one case, due to intra-operational difficulties, the Te Linde correction was used. The average age of the patients was 63.7 (47-95 years), parity of 4.6 and BMI of 26.9. ASP was performed on average 18 years after total abdominal hysterectomy and 3 years after vaginal hysterectomy. The average surgical time was 2 h and 15 min, without the need of a blood transfusion. There were no recurrences of the prolapse or preoperative symptoms (follow-up of 1-5 years). CONCLUSIONS: surgical treatment of the vaginal vault prolapse can be done by vaginal access (colpocleisis or the fixation to the sacrospinal ligament) or abdominal approach (sacropexy). The latter has the advantage of restoring the vaginal axis, preserving its depth, which apart from improving the prolapse, allows the restoration of sexual, intestinal and urinary functions (especially when associated with colpofixation - Burch). When diagnosis and treatment are adequate and the surgical team has complete knowledge of the pelvic anatomy, we can affirm that ASP reaches its objective in the treatment of vaginal vault prolapse with excellent correction and minimum morbidity.

PURPOSE: to compare the characteristics of human semen preserved at +4ºC and at -196ºC for 24 h and to determine which technique is indicated for use in specific procedures. METHODS: semen samples of 24 voluntaries were analyzed after collection and divided into two aliquots, one of them cooled (+4ºC) and the other frozen (-196ºC). Samples were kept at low temperatures for 24 h and then at room temperature for 30 minutes (T1), capacitated (T2) and kept at +37ºC for 90 minutes (T3), being analyzed regarding count and progressive motility at T1, T2 and T3. The General Linear Model was used to analyze results obtained with different techniques, while Wilcoxon's test was used to compare results obtained in two different moments using the same technique (a = 5% e p<0,05). RESULTS: data were missed in one fresh semen sample, in one sample after preservation, in five samples after capacitation and in two samples after incubation. The average number of total motile sperm/mL (NTMS) in fresh semen was 39.7 million (1.3-104.0). After preservation, the average NTMS in cooled semen was 9.6 million (0-37.4) and in frozen semen 8.7 million (0-41.2). After capacitation, the average NTMS was 5.4 million either in cooled (0-21.7), or in frozen semen (0-28). After incubation, the average NTMS in cooled semen was 9.8 million (0-40.5) and in frozen 4.4 million (0-25.6). Concerning count, progressive motility and NTMS, there was no significant difference (p>0,05) between techniques in the three moments of observation. In cooled samples, there was no difference between variables after capacitation and after incubation, but, in frozen semen, count was significantly greater after capacitation. CONCLUSIONS: although there has been no significant difference between semen count and progressive motility in both techniques, the use of cooled semen is recommended for specific procedures within a short time period due to its simplicity and low cost. When frozen semen is necessary, we recommend its use soon after capacitation in order to avoid loss in quality.

PURPOSE: to evaluate the adequacy of the prenatal care process offered to users of the Unified Health Care System (SUS) in Juiz de Fora-MG and to compare the municipal services. METHODS: a transversal study with auditing was carried out on the records of 370 pregnant women, selected by systematic sampling among women who carried their pregnancies to term and gave birth using SUS services in the first semester of 2002, with prenatal care given in Juiz de Fora. For statistical analysis the c² test was used to compare the municipal services (level of significance: 5%). The evaluation followed a three-tiered complementary sequence, using: the utilization of prenatal care (Kessner index: beginning and frequency of care) at level 1; the utilization of prenatal care and basic laboratory tests, according to the Humanization Program of Prenatal Care and Birth (ABO-Rh, hemoglobin/hematocrit, VDRL, glycemia and urinalysis), at level 2; and the utilization of prenatal care, the basic laboratory tests and the obligatory clinical-obstetric procedures during a prenatal visit (assessment of blood pressure, weight, edema, uterine fundal height, gestational age, fetal heart rate and fetal presentation), at level 3. RESULTS: the observed adequacy of the process was only 26.7% (level 1), 1.9% (level 2) and 1.1% (level 3). We also observed a prenatal coverage of 99.04%, an average of 6.4 visits per pregnant woman, and an average gestational age of 17.4 weeks at the time of the first prenatal visit. There were no significant differences between the municipal services. CONCLUSIONS: prenatal care offered to SUS users in Juiz de Fora should be reviewed from a qualitative standpoint, and periodic evaluations as necessary instruments of improvement are recommendable. Managers and professionals should undertake actions aimed at increasing compliance with norms/routines of the program - principally the request/recording of basic complementary tests - and which guarantee increased utilization of prenatal care.

PURPOSE: to evaluate the perinatal outcome of fetuses with congenital anomalies of the urinary tract. METHODS: we reviewed the perinatal outcome of 35 fetuses with congenital anomalies of the urinary tract. The following characteristics related to the uropathy were analyzed: type (hydronephrosis, dysplasia and renal agenesis), side of lesion (bilateral or unilateral), and level of the obstruction (high or low, in hydronephrosis). The perinatal outcome was evaluated according to these characteristics. The data were analyzed by the c² test and by the exact Fisher test. The level of significance was 0.05. RESULTS: the incidence of hydronephrosis was 68.6%. Half of the fetuses had unilateral hydronephrosis. Renal dysplasia occurred in 17.1% of the cases; 83.3% of these were bilateral and 16.7%, unilateral. The incidence of renal agenesis was 14.3%, all bilateral. The fetuses with dysplasia/agenesis had a 91% incidence of oligohydramnios, preterm birth, low birth weight, and death. In the group with bilateral disease the presence of oligohydramnios, preterm birth, low birth weight, death, urinary tract infections, and the need of hospitalization for a period greater than 7 days was significant when compared to the group with unilateral disease. The need of hospitalization for a period greater than 7 days in patients with low obstruction was significantly higher when compared to the patients with high obstruction. CONCLUSIONS: hydronephrosis, bilateral disease, and lower obstruction were the most frequent uropathies. The dysplasia/agenesis group had a worse prognosis when compared with the hydronephrosis group. Bilateral disease had a worse prognosis when compared with the unilateral disease group. In the low obstruction group, the need for a period of hospitalization greater than seven days was higher than in the high obstruction group.

PURPOSE: to evaluate, in pregnant adolescents, the incidence of iron deficiency, using the following blood tests: hemoglobin, ferritin, serum iron, transferrin saturation rate and serum transferrin receptor, and their relationships. METHODS: a total of 56 adolescents were included at the first prenatal evaluation between the 12th and the 20th week of gestation. The normal values for each test were: above 11 mg/dL for hemoglobin, 12 µg/dL for ferritin, 50 mg/L for serum iron, 16% for transferrin saturation rate and below 28.1 nmol/L for serum transferrin receptor. Each result was evaluated using percentages and the McNemar test was used to compare the results. RESULTS: incidence of anemia using the hemoglobin concentration test was 21.4%. All pregnant women presented mild anemia. In the present study, 21.4% of the patients had iron deficiency with a ferritin concentration <12 mug/dL. Serum iron concentration was reduced in 3.6% of the adolescents and transferrin saturation rate in 26.8% of the sample. The value obtained by the transferrin receptor test was unclear, due to the lack of international standardization regarding measure unit. Comparing the hemoglobin concentration test to the other iron deficiency tests, it was found that the latter do not show a better evaluation than the hemoglobin concentration test in patients with hypoferremia. CONCLUSIONS: the hemoglobin concentration test in patients with mild anemia was effective to identify iron deficiency.

PURPOSE: to verify the contribution of maternal age, parity, twin pregnancy, hypertensive syndrome, and premature rupture of membranes as risk factors for cesarean section. METHODS: after approval by the Ethics in Research Committee of the "Maternidade Professor Monteiro de Morais" - Recife, PE - Brazil, for a case control study, the authors analyzed data from 3919 pregnant women, without two or more prior cesarean sections, who gave birth to alive newborns with gestational age equal to or more than 28 weeks, weighing at least 1,000 g, on cephalic presentation, from September 1, 1999 to August 31, 2000. The case group included women submitted to cesarean section and the control group included women submitted to vaginal delivery. With the data collected from obstetric and neonatal reports, the authors performed multivariate analysis by logistic regression to determine a mathematical equation that associates cesarean probability due to more than one independent variable acting as risk factor, determining odds ratio with a confidence interval of 95% (95% CI), for the variables: maternal age, parity, twin pregnancy, hypertensive syndrome, and premature rupture of membranes. RESULTS: the chances for cesarean section significantly increased 8.3 times in twin pregnancy (OR = 8.3; 95% CI: 3.7-19.1), 3.4 in hypertensive syndrome (OR = 3.4; 95% CI: 2.9-4.0), 1.9 in primiparity (OR = 1.9; 95% CI: 1.8-2.0), 1.5 in maternal age over 34 years (OR = 1.5; 95% CI: 1.2-1.8), and 1.2 in the presence of premature rupture of membranes (OR = 1.2; 95 %CI: 1.0-1.4). CONCLUSIONS: the risk for cesarean section was greater in the presence of premature rupture of membranes, maternal age greater than 34 years, primiparity, hypertensive syndrome, and twin pregnancy.

Ehlers-Danlos syndrome is a connective tissue disease that is rarely associated with pregnancy, but with potentially fatal complications during pregnancy and puerperium, such as vascular and intestinal ruptures. It can also be associated with joint laxity and pain in women; during pregnancy there is a greater risk of prematurity, because of premature rupture of membranes and/or cervical insufficiency. Uterine rupture and inversion can also be associated with this syndrome. In the present study, we describe the case of a pregnant woman with Ehlers-Danlos syndrome, with a favorable evolution, without fetal complications and a good perinatal outcome.

Fallopian tube prolapse is a rare complication after hysterectomy, with approximately 80 cases described in the literature. The symptoms are nonspecific including vaginal bleeding, dyspareunia and chronic pelvic pain. The differential diagnosis must be done with granulation tissue of the vaginal cuff and vaginal carcinoma. The treatment should be individualized, and is possible to be done by vaginal, abdominal or laparoscopic approach. We report a case of a 47-year-old woman with myoma who was submitted to a vaginal hysterectomy and evolved with fallopian tube prolapse 11 months after surgery. Specular examination showed a fungating, friable and bleeding lesion at the vaginal cuff. The clinical findings suggested the diagnosis of fallopian tube prolapse. The patient was submitted to a new surgical intervention with resection of the left fallopian tube. The histologic examination confirmed the diagnosis and the patient evolved with complete remission of the symptoms.
