- Is Doppler ultrasound useful for evaluating gestational trophoblastic disease?(2015) LIN, Lawrence H.; BERNARDES, Lisandra S.; HASE, Eliane A.; FUSHIDA, Koji; FRANCISCO, Rossana P. V.Doppler ultrasound is a non-invasive method for evaluating vascularization and is widely used in clinical practice. Gestational trophoblastic neoplasia includes a group of highly vascularized malignancies derived from placental cells. This review summarizes data found in the literature regarding the applications of Doppler ultrasound in managing patients with gestational trophoblastic neoplasia. The PubMed/Medline, Web of Science, Cochrane and LILACS databases were searched for articles published in English until 2014 using the following keywords: ""Gestational trophoblastic disease AND Ultrasonography, Doppler."" Twenty-eight articles met the inclusion criteria and were separated into the 4 following groups according to the aim of the study. (1) Doppler ultrasound does not seem to be capable of differentiating partial from complete moles, but it might be useful when evaluating pregnancies in which a complete mole coexists with a normal fetus. (2) There is controversy in the role of uterine artery Doppler velocimetry in the prediction of development of gestational trophoblastic neoplasia. (3) Doppler ultrasound is a useful tool in the diagnosis of gestational trophoblastic neoplasia because abnormal myometrial vascularization and lower uterine artery Doppler indices seem to be correlated with invasive disease. (4) Lower uterine artery Doppler indices in the diagnosis of gestational trophoblastic neoplasia are associated with methotrexate resistance and might play a role in prognosis. CONCLUSION: Several studies support the importance of Doppler ultrasound in the management of patients with gestational trophoblastic neoplasia, particularly the role of Doppler velocimetry in the prediction of trophoblastic neoplasia and the chemoresistance of trophoblastic tumors. Doppler findings should be used as ancillary tools, along with human chorionic gonadotropin assessment, in the diagnosis of gestational trophoblastic neoplasia.
- Fetal growth according to different reference ranges in twin pregnancies with placental insufficiency(2015) NAKANO, Julianny Cavalheiro Nery; LIAO, Adolfo Wenjaw; BRIZOT, Maria de Lourdes; MIYADAHIRA, Mariana; FRANCISCO, Rossana Pulcineli Vieira; ZUGAIB, MarceloThe aim of this study was to compare different fetal growth curves in twin pregnancies with severe placental insufficiency. A retrospective cross-sectional analysis of 47 twin pregnancies with absent or reverse end diastolic flow in the umbilical artery of one fetus was performed. Pregnancies with major fetal abnormalities, twin-twin transfusion or three or more fetuses were not included. The estimated fetal weight zeta-scores were calculated for both fetuses (abnormal Doppler and co-twin) according to the following criteria: Hadlock, Liao and Araujo. The abdominal circumference zeta-scores were calculated according to Hadlock, Liao, Araujo, Ong and Stirrup. The mean estimates of the zeta-score values were calculated using generalized estimating equation regression analysis. The mean gestational age at inclusion was 27.4 +/- 4.7 weeks. The fetal sex and the interaction Doppler findings x criteria correlated significantly with the zeta-score values (p<0.001 for both variables). The estimated fetal weight mean zeta-scores (standard error) according to each criteria were as follows: Hadlock - abnormal Doppler: -2.98 (0.18), co-twin: -1.16 (0.15); Liao -abnormal Doppler: -2.89 (0.24), co-twin: -0.58 (0.19); and Araujo - abnormal Doppler: -3.05 (0.29), co-twin: -0.75 (0.18). Values for abdominal circumference were as follows: Hadlock -abnormal Doppler: -3.14 (0.26), co-twin: -1.13 (0.19); Liao -abnormal Doppler: -2.63 (0.27), co-twin: -0.42 (0.19); Araujo abnormal Doppler: -2.44 (0.22), co-twin: -0.71 (0.14); Ong -abnormal Doppler: -3.36 (0.34), co-twin: -1.48 (0.23); and Stirrup AD - -2.36 (0.14), co-twin: -1.18 (0.10). Sex-and plurality-specific charts should be used in the evaluation of fetal growth in twin pregnancies with placental insufficiency.
- Pregnancy of unknown location(2019) PEREIRA, Pedro Paulo; CABAR, Fabio Roberto; GOMEZ, Ursula Trovato; FRANCISCO, Rossana Pulcineli VieiraPregnancy of unknown location is a situation in which a positive pregnancy test occurs, but a transvaginal ultrasound does not show intrauterine or ectopic gestation. One great concern of pregnancy of unknown location is that they are cases of ectopic pregnancy whose diagnosis might be postponed. Transvaginal ultrasound is able to identify an ectopic pregnancy with a sensitivity ranging from 87% to 94% and a specificity ranging from 94% to 99%. A patient with pregnancy of unknown location should be followed up until an outcome is obtained. The only valid biomarkers with clinical application and validation are serum levels of the beta fraction of hCG and progesterone. A single serum dosage of hCG is used only to determine whether the value obtained is above or below the discriminatory zone, that means the value of serum hCG above which an intrauterine gestational sac should be visible on ultrasound. Serum progesterone levels are a satisfactory marker of pregnancy viability, but they are unable to predict the location of a pregnancy of unknown location: levels below 5 ng/mL are associated with nonviable gestations, whereas levels above 20 ng/mL are correlated with viable intrauterine pregnancies. Most cases are low risk and can be monitored by expectant management with transvaginal ultrasound and serial serum hCG levels, in addition to the serum progesterone levels. To minimize diagnostic error and intervene during progressive intrauterine gestation, protocol indicates active treatment only in situations when progressive intrauterine pregnancy is excluded and a high possibility of ectopic pregnancy exists.
- An unfavorable intrauterine environment may determine renal functional capacity in adulthood: a meta-analysis(2018) SENRA, Janaina Campos; CARVALHO, Mariana Azevedo; RODRIGUES, Agatha Sacramento; KREBS, Vera Lucia Jornada; GIBELLI, Maria Augusta Bento Cicaroni; FRANCISCO, Rossana Pulcineli Vieira; BERNARDES, Lisandra SteinSince studies show that an unfavorable environment during intrauterine development predisposes individuals to several diseases in adulthood, our objective is to assess the relation between fetal growth restriction and chronic renal disease in adults. We searched four different electronic databases through November 2017: CENTRAL, EMBASE, LILACS and MEDLINE. We selected studies with longitudinal or transversal designs associating kidney function in adulthood with low birth weight. Two reviewers evaluated the inclusion criteria and the risk of bias and extracted data from the included papers. Thirteen studies were selected for the systematic review and meta-analysis. We observed increased risks of presenting end-stage renal disease (risk ratio 1.31, 95% confidence interval: 1.17, 1.47), a lower glomerular filtration rate (ml/min) (mean difference 7.14; 95% confidence interval: -12.12, -2.16), microalbuminuria (risk ratio 1.40; 95% confidence interval: 1.28, 1.52) and a small increase in the albumin/creatinine ratio (mean difference 0.46; 95% confidence interval: 0.03, 0.90) in the low birth weight patients, compared with control group. These findings suggest that low birth weight is associated with renal dysfunction in adults.
