PURPOSE: To describe the maternal and perinatal outcomes of pregnant women diagnosed with leukemia who were followed up for prenatal care and delivery at a university hospital. METHODS: A retrospective study of the period from 2001 to 2011, which included 16 pregnant women with a diagnosis of leukemia followed by antenatal care specialists in hematological diseases and pregnancy. For acute leukemia diagnosed after the first trimester, the recommendation was to perform chemotherapy despite the current pregnancy. For chronic leukemia, patients who were controlled in hematological terms were maintained without medication during pregnancy, or chemotherapy was introduced after the first trimester. We analyzed the maternal and perinatal outcome. RESULTS: Acute lymphoblastic leukemia (ALL) was diagnosed in five cases (31.3%), acute myeloid leukemia (AML) in two cases (12.5%) and chronic myeloid leukemia (CML) in nine cases (56.3%). Of the cases of acute leukemia, two (28.6%) were diagnosed in the first trimester, two (28.6%) in the second and three (42.9%) in the third. Two patients with ALL diagnosed in the first trimester opted for therapeutic abortion. Four patients with acute leukemia received chemotherapy during pregnancy, with a diagnosis established after the 20th week. In one case of ALL with a late diagnosis (30 weeks), chemotherapy was started after delivery. All pregnant women with acute leukemia developed anemia and thrombocytopenia, and four (57.1%) developed febrile neutropenia. Of nine pregnant women with CML, four were treated with imatinib mesylate when they became pregnant, with treatment being interrupted in the first trimester in three of them and in the second trimester in one. During pregnancy, three patients (33.3%) required no chemotherapy after discontinuation of imatinib, and six (66.7%) were treated with the following drugs: interferon (n=5) and/or hydroxyurea (n=3 ). In the group of pregnant women with CML, anemia occurred in four (44.4%) cases and thrombocytopenia in one (11.1%). The perinatal outcomes of pregnancies complicated by acute leukemia were as follows: mean gestational age at delivery was 32 weeks (standard deviation - SD=4.4) and the mean birth weight was 1476 g (SD=657 g), there were 2 (40.0%) perinatal deaths (a fetal one and a neonatal one). In pregnancies complicated by CML, the mean gestational age at delivery was 37.6 weeks (SD=1.1) and the mean birth weight was 2870 g (SD=516 g). There was no perinatal death and no fetal abnormality was detected. CONCLUSIONS: Maternal and fetal morbidity is high in pregnancies complicated by acute leukemia. Whereas, in pregnancies complicated by CML, the maternal and fetal prognosis appears to be more favorable, with greater ease in management of complications.

PURPOSE: To determine the accuracy of ultrasound in fetal weight estimation and to evaluate maternal and/or fetal factors that could interfere in the result. METHODS: This was a transverse prospective study, involving 106 patients, with 212 fetal weight evaluations, by two observers, within 24 h to delivery. The following parameters were measured: biparietal diameter, head circumference, abdominal circumference, and femoral length. Fetal weight was estimated using the Hadlock formula and the results were compared to birth weight. The maternal factors examined were: weight, BMI, and skin to uterus distance measured by ultrasound, and the fetal factors were: presentation, position, placental localization and thickness, fetal weight, and amniotic fluid index (AFI). RESULTS: There was good correlation between estimated fetal weight and birth weight (R=0.97). In 79.2% and in 92.4% of cases the estimated fetal weight was within 10% and 15% of birth weight, respectively. The only maternal factor that presented a positive correlation with percent error in the estimate of fetal weight was the skin to uterus distance (R³0.56). Fetal weight showed negative correlation with percent error (R>-0.36; p<0.001), with a significant tendency to overestimate fetal weight in the group of very low weight - <1000 g (p<0.05). The AFI showed a low negative correlation with percent error (R=-0.21; p<0.001) with no difference between AFI groups (p=0.516). CONCLUSION: Ultrasound presented good accuracy in the estimation of fetal weight. The error of weight estimate was directly proportional to the skin to uterus distance and inversely proportional to fetal weight. AFI did not interfere significantly in the ultrasound prediction of fetal weight.

PURPOSE: To compare and analyze socioeconomic aspects and the emotional experience of women with spontaneous or induced abortion and in women living in the outskirts of São Paulo. METHODS: A prospective case-control study carried out from July 2008 to March 2010, involving semi-structured interviews with women who presented a previous diagnosis of abortion and who had been admitted to two public hospitals in the outskirts of São Paulo. The study included 100 women with diagnosis of abortion and were hospitalized for curettage. Eleven women who reported induced abortion (11%) represented the case group. The control group (n=22) was selected at a 2:1 ratio according to the following procedure: for every case of induced abortion, the next two cases of spontaneous abortion at the same hospital. A semistructured interview was conducted with questions regarding emotional aspects and family, social and economic context. RESULTS: The women with induced abortion compared to the group with spontaneous abortion had lower educational level, with more frequent elementary level (82 versus 36%, p=0.04), lower income (median, R$ 1,000.00 versus R$ 1,400.00, p=0.04), lower personal income (median, R$ 200.00 versus R$ 333.00, p=0.04), higher frequency of negative feelings upon suspicion (82 versus 22%, p=0.004) and confirmation (72 versus 22%, p=0.03) of pregnancy. CONCLUSION: Among women looking for health care in hospitals in the outskirts of São Paulo, induced abortion is related to unfavorable socioeconomic conditions, which affects the emotional experiences of suspicion and confirmation of pregnancy.

PURPOSE: To analyze the results of assessment of fetal well-being in pregnancies complicated by moderate or severe maternal thrombocytopenia. METHODS: Data from April 2001 to July 2011 of 96 women with a diagnosis of thrombocytopenia in pregnancy were retrospectively analyzed. We analyzed the following tests performed during the antepartum period for fetal assessment: cardiotocography, fetal biophysical profile, amniotic fluid index and umbilical artery Doppler velocimetry. RESULTS: A total of 96 pregnancies with the following diagnoses were analyzed: gestational thrombocytopenia (n=37, 38.5%) hypersplenism (n=32, 33.3%), immune thrombocytopenic purpura (ITP, n=14, 14.6%), secondary immune thrombocytopenia (n=6, 6.3%), bone marrow aplasia (n=3, 3.1%), and others (n=4, 4.1%). Cardiotocography showed normal results in 94% of cases, a fetal biophysical profile with an index of 8 or 10 in 96.9% and an amniotic fluid index >5.0 cm in 89.6%. Doppler umbilical artery velocimetry showed normal results in 96.9% of cases. In the analysis of the major groups of thrombocytopenia, the diagnosis of oligohydramnios was found to be significantly more frequent in the group with ITP (28.6%) compared to the other groups (gestational thrombocytopenia: 5.4% and hypersplenism: 9.4%, p=0.04). CONCLUSIONS: This study indicates that in pregnancies complicated by moderate or severe maternal thrombocytopenia, even though the fetal well-being remains preserved in most cases, fetal surveillance is important in pregnant women with ITP, with emphasis on amniotic fluid volume evaluation due to its association with oligohydramnios.

Purpose: to study computerized cardiotocography performed in high-risk pregnancies, analyze the results, and correlate the criteria to perinatal results. Patients and Methods: two hundred and thirty-three high-risk pregnancies were studied prospectively, performing a total of 485 computerized cardiotocographies. The exclusion criteria included fetal anomalies and signal loss over 20% (proportion of 3.75-millisecond periods in which there were no valid pulse intervals). The perinatal results of 71 pregnancies were correlated to the last cardiotocography, performed at least seven days before birth, excluding patients with absent or reversed end diastolic velocities in the umbilical arteries. Results: thirty-three examinations with signal loss over 20% were excluded. The normal criteria were met in 404 (83.3%), and 62.1% examinations met the criteria within 20 minutes and 79% within 30 minutes. The abnormal computerized cardiotocography was related significantly (p<0.05) to adverse perinatal results, such as: preterm delivery, first minute Apgar score less than 7 (33%), neonatal intensive care admission (55.5%) and intubation of newborn at delivery (44.4%). Conclusions: computerized cardiotocography in high-risk pregnancies met the normal criteria in most of the cases, with the examination performed for 30 minutes. The cases that did not meet the criteria correlated significantly to adverse perinatal results.
