En ausencia de cribado serológico sistemático, el diagnóstico de infección fetal suele hacerse a partir de una ecografía habitual, que revela anomalías ecográficas indicativas de tal afección. En el caso que se presenta las anomalies aparecieron de forma progresiva, inicialmente una hiperecogenicidad intestinal con oligoamnios en la semana 17 y, posteriormente, ventriculomegalia, hepatomegalia y ascitis en la semana 21, cuando se realizó el diagnóstico de la infección mediante estudio de la reacción en cadena de la polimerasa (PCR) en el líquido amniótico.Cytomegalovirus is the most frequent congenital infection with an incidence of approximately 1% and a high rate of fetal involvement and sequelae. In the absence of universal screening, diagnosis of this infection is usually based on abnormal findings during routine ultrasound scan. We present a case showing progressive abnormalities on ultrasound. Initial abnormal findings consisted of hyperechogenic bowel and oligohydramnios at 17 weeks and subsequent abnormalities consisted of marked ventriculomegaly, hepatomegaly and ascites at 21 weeks when cytomegalovirus was detected in the amniotic fluid by polymerase chain reaction.

To our knowledge no data currently are available on the effect of race on oocyte donation outcome. materials: A retrospective, matched cohort study was performed in a private infertility centre evaluating 1012 Black, South-East Asian and Caucasian recipients undergoing their first oocyte donation cycles.

We conducted a retrospective analysis on the outcome of this subgroup. METHODS: Thirty oocyte donation cycles with fresh embryo transfer were performed in 21 patients between 2001 and 2004. RESULTS: The mean (±SD) age of the recipients was 33.1 ± 1.8 years. The median (range) number of transferred embryos per cycle was two (1-4). Seventeen pregnancies were obtained (57%), of which 12 were clinical (40%). The implantation rate and the ongoing pregnancy rate were 22% (15 out of 68) and 30% (nine out of 30), respectively. Premature delivery was observed in 50% (four out of eight) of the pregnancies and intrauterine growth retardation in 55.5% (five out of nine) of the fetuses. Hypertensive disorders occurred in five out of eight pregnancies (three preeclampsias). CONCLUSIONS: Turner's syndrome patients achieve acceptable pregnancy rates after oocyte donation. A high rate of pregnancy-associated hypertensive disorders was observed which have led to a high rate of prematurity and intrauterine growth restriction. Although the number of cases in this study is limited, these results call for the need for intensive surveillance of such pregnancies. In order to reduce the risk of hypertensive disorders induced by multiple pregnancies, single embryo transfer should be proposed.

Prospective cohort study from the Hospital Clínic in Barcelona, Spain. 36 HIV-infected and 36 non HIV-infected pregnant women were included, matched by age and parity. Maternal blood samples were obtained during the first trimester, third trimester and at delivery. sCD14, Human Lipopolysaccharide Binding Protein, IgMEndoCAb and IL-6 were determined. Fetal cord blood sCD14, LBP and IL-6 were tested. Results were compared between groups. First trimester sCD14 and LBP levels, and third trimester sCD14 levels were significantly higher in the HIV-infected group. HIV-infected women with preterm births and spontaneous preterm births presented significantly increased levels of sCD14 during all pregnancy and LBP in the first trimester compared to HIV-infected women with delivery at term or HIV negative women. On multivariate analysis, an independent association was observed between first trimester sCD14 levels and preterm delivery among HIV-infected women. This is the first study to assess inflammatory markers related to microbial translocation in HIV pregnancies. Higher levels of sCD14 and LBP were observed in HIV-infected pregnant women, being associated with preterm delivery.

Therefore, we conducted a matched controlled analysis on the outcome of OD in these recipients. Between January 2000 and November 2005, 33 patients with a history of chemotherapy and/or radiotherapy had an OD cycle. Matching was performed to the chronologically closest patient without a history of cancer therapy by number of days of hormonal stimulation before embryo replacement, number of replaced embryos, day of embryo transfer and origin of sperm. The primary diseases of the patients were Hodgkin's lymphoma (n = 12), non-Hodgkin's lymphoma (n = 3), leukaemia (n = 7), ovarian cancer (n = 6), Ewing's sarcoma (n = 2), breast cancer (n = 1), sympathoblastoma (n = 1) and histiocytosis X (n = 1). Twenty-three patients had undergone chemotherapy and radiotherapy, nine patients chemotherapy only and one radiotherapy only. The mean age of the recipients was 33.1 ...

Matched case-control single-center study. Private infertility clinic. Four hundred forty-four recipients (222 pairs) sharing oocytes from the same donor and showing a discordant outcome. Controlled ovarian hyperstimulation of egg donors, oocyte donation, intracytoplasmic sperm injection, and ET in egg recipients. Recipient age, obstetric (gravidity, parity) and gynecologic variables (previous uterine surgery, uterine fibroids, uterine malformations, endometriosis, history of tubal infertility), previous oocyte donation cycles, duration of E(2) replacement, received cumulus-oocyte complexes, mature (MII) oocytes, fertilized oocytes, transferred embryos, mean embryo score, transfer difficulty, and semen parameters. No significant differences were found in the above-mentioned prognostic factors between the study and control groups. Recipient- and cycle-rela...

Fetal AoI Doppler parameters were assessed in either the longitudinal aortic arch view or the three vessels and trachea view. Regression analysis was used to determine gestational-age-specific reference ranges and to construct nomograms for the following Doppler parameters: pulsatility index (PI), resistance index (RI) and peak systolic (PSV), end-diastolic (EDV) and timeaveraged maximum (TAMXV) velocities. Intra-and interobserver reproducibility were evaluated by calculating intraclass correlation coefficients (ICCs) and limits of agreement.
