OBJECTIVE: to evaluate the existence of intra and intercytophathologists disagreement in the analysis of cervical slides previously diagnosed as atypical skin cells with undetermined significance (ASCUS), and the degree of this disagreement. METHODS: a transversal study of 50 cervical slides of Pap smears previously diagnosed as ASCUS, collected in November 2000 in Contagem town. They were analyzed and classified by four cytopathologists according to the first Bethesda system review of 1991 (normal, atrophic alteration, inflammatory alteration, suggestive of LoSIL, suggestive of HiSIL, suggestive of invasive carcinoma and others). After the first analysis, the slides were renumbered in a random order and sent to the same cytophathologists for a new exam. The Kappa test and the weighted Kappa were used in the analysis of the results. RESULTS: there was a high degree of disagreement between the different analyses of the same cytopathologist, varying from 7.8 to 74.4% according to the Kappa test. When a weight of 20% was settled for each degree of disagreement, these values increased from 16.1% for the cytopathologist A to 81.08% for the cytopathologist B. Concerning the comparative analyses made by different examiners the Kappa test values obtained varied from 50.6% to 63.4% in the normal and weighted versions, respectively. CONCLUSIONS: this study confirms the existence of subjectivity in the analysis of the ASCUS category and imprecision in the analysis criteria by the same examiner.

, Vasa previa (VP) is a dangerous obstetric condition associated with perinatal mortality and morbidity. In vitro fertilization (IVF) is a risk factor for VP due to the high incidence of abnormal placentation. The diagnosis should be made prenatally, because fetal mortality can be extremely high. We report two cases to demonstrate the accuracy of transvaginal ultrasound in the prenatal diagnosis of VP. A 40-year-old primiparous Caucasian woman with IVF pregnancy was diagnosed with VP at 29 weeks of gestation and was hospitalized for observation at 31 weeks of gestation. She delivered a male newborn weighing 2,380 g, with an Apgar score of 10 at 5 minutes, by elective cesarean section at 34 weeks + 4 days of gestation, without complications. A 36-yearold primiparous Caucasian woman with IVF pregnancy was diagnosed with placenta previa, bilobed placenta increta and VP. The cord insertion was velamentous. She was hospitalized for observation at 26 weeks of gestation. She delivered a female newborn weighing 2,140 g, with an Apgar score of 9 at 5 minutes, by emergency cesarean section at 33 weeks + 4 days of gestation due to vaginal bleeding. The prenatal diagnosis of VP was associated with a favorable outcome in the two cases, supporting previous observations that IVF is a risk factor for VP and that all IVF pregnancies should be screened by transvaginal ultrasound.

OBJECTIVE: to describe ultrasonographic alterations in fetuses infected with Toxoplasma gondii, correlating them with neonatal prognosis. METHODS: between June 1997 and May 2003, 150 pregnant women with suspected toxiplasmosis were examined. Acute infection was confirmed in 72 (48%) of these pregnant women and congenital toxoplasmosis was diagnosed in 12 (16%) fetuses. Prenatal diagnosis was established by polymerase chain reaction in the amniotic fluid. All the patients received antiparasitic therapy. Ultrasound examination was performed every fortnight and all the infants were evaluated during their first year of life. RESULTS: ultrasonographic changes were observed in eight fetuses. All of them showed symmetric bilateral ventricular enlargement that was associated with periventricular calcifications in five cases. Other changes as hepatic calcification, hepatomegaly, polyhydramnium, and pericardial effusion were less frequent. Among these fetuses, four were stillborn and three showed sequelae (chorioretinitis and neuro-psychomotor retardation). The four fetuses that showed normal ultrasonography had a satisfactory development. CONCLUSION: There was a high incidence of ultrasonographic changes in fetuses with congenital toxoplasmosis, mainly brain damage. Other changes as hepatomegaly and pericardial effusion were less frequent and were related to a systemic infection. The prognosis of these fetuses seems to be correlated with the presence of these lesions mainly because they had high mortality ratio and among the survivors the incidence of sequelae was high. The non-symptomatic fetuses evolved in a favorable way without developing sequelae. These results highlight the value of ultrasonographic examination of these fetuses in order to establish a prognosis and allow the elaboration of a suitable post-natal procedure.

Purpose: to evaluate the effectiveness of diagnostic amnioinfusion in severe oligohydramnios. Methods: twelve patients with severe oligohydramnios in the second and third trimester of pregnancy were submitted to amnioinfusion. The procedure was done using a warm physiological saline at a rate of 20 mL/min followed by the instillation of 5 mL of dye. The amniotic fluid index (AFI) was measured before the procedure and 30 min afterwards and in case of fetal anomalies, it was documented. The gestational age ranged from 18 to 34 weeks (average 25 ± 4 weeks). The average of the initial ILA was 10.3cm and after the procedure was 16.4 cm. The volume of saline solution infused ranged from 300 to 1000 mL (605.4 ± 224.1 mL). Results: in nine patients (75%) the procedure led to an etiologic diagnosis: four cases of premature rupture of membranes and major malformations in five fetuses. In two patients the oligohydramnios was considered idiopathic and in one patient the pathological examination revealed a placental infarct. Nine pregnancies (75%) were interrupted after the diagnosis and in three cases it was maintained for 8.8 weeks after the amnioinfusion. All fetuses died, seven of them had neonatal death and the remaining had intrauterine death. Conclusion: amnioinfusion is an effective method with high precision, enabling the etiologic diagnosis of severe oligohydramnios in 75% of the cases.

Twin pregnancy with an acardiac twin is a rare event characterized by the presence of a placentary arterial anastomosis between the pump twin, morfologically normal, and the acardiac twin, causing a reverse circulation in one of the twins. The major complications are associated with cardiac failure in the normal twin, which is due to circulatory overload and prematurity. Many therapeutic options have been proposed, but there is no consensus about which one is the best therapy. However, intrafetal ablation of the umbilical artery of the acardiac fetus proved to be an inexpensive method that is easy to perform and highly efficient in controlling circulatory overload. We presented two cases of intra-fetal ablation and good evolution. A triplet pregnancy in which the intra-fetal ablation was done in a 29-week-old fetus that evolved to premature delivery of a healthy baby, and a twin pregnancy in which intra-fetal ablation was done in a 31-week-old fetus that evolved to premature rupture of membranes and the premature delivery of a healthy baby.
