We describe Zika virus (ZIKV) vertical transmission in an imported case in Spain, in a 17-week pregnant woman. ZIKV IgG, IgM and RNA were detected in serum in week 17. At 19 weeks, ultrasound scan revealed fetal malformations and ZIKV was detected in the amniotic fluid. Pregnancy was terminated at week 21; autopsy of the fetus revealed bilateral hydrocephalus, brain microcalcifications and arthrogryposis multiplex congenita. ZIKV was detected in the umbilical cord and brain tissue.

Amniotic fluid embolism (AFE) is a rare presentation in obstetric emergencies that carries great risk for the life of both mother and fetus. It is usually characterized by sudden cardiovascular collapse, respiratory distress and disseminated intravascular coagulation. Here we present a case of sudden death of a pregnant woman due to suspected AFE. We also present a rare finding of natal teeth in her deceased baby, which along with reported AFE in the mother, is an unlikely event in the medical literature.

Abstract Background Trisomy 8 mosaicism has a wide phenotypic variability, ranging from mild dysmorphic features to severe malformations. This report concluded a female pregnant woman with trisomy 8 mosaicism, and carefully cytogenetic diagnoses were performed to give her prenatal diagnostic information. This report also provides more knowledge about trisomy 8 mosaicism and the prenatal diagnostic for clinicians. Case presentation In this present study, we reported one case of pregnancy woman with trisomy 8 mosaicism. Noninvasive prenatal testing prompted an abnormal Z-score, but further three dimension color ultrasound result suggested a single live fetus with no abnormality. The phenotypic of the pregnant woman was normal. Based on our results, there were no abnormal initial myeloid cells (< 10− 4), which suggested that the patient had no blood diseases. The peripheral blood karyotype of the patient was 47,XX,+ 8[67]/46,XX [13], and karyotype of amniotic fluid was 46, XX. The next generation sequencing (NGS) result suggested that the proportions of trisomy 8 in different tissues were obviously different; and 0% in amniotic fluid. Last, the chromosomes of the patient and her baby were confirmed using chromosome microarray analysis (CMA), and the results were arr[GRCh37](8) × 3,11p15.5p13(230750–33,455,733) × 2 hmz and normal. Conclusions This pregnancy woman was trisomy 8 mosaicism, but the phenotypic was normal, and also the fetus was normal. Carefully cytogenetic diagnoses should be performed for prenatal diagnose.

The ability to examine amniotic fluid obtained by amniocentesis during the second trimester of pregnancy is a significant new advance in the practice of clinical genetics.1 We here report a rapid and accurate method for determining fetal sex, which should be useful when the pregnant woman is a carrier of a serious sex-linked disease such as muscular dystrophy or hemophilia. The method makes use of the selective concentration of fluorescent stains by the Y chromosome in interphase cells.2,3 Recently two observers have reported their preliminary observations on amniotic fluid cells using fluorescent techniques.4,5

Background Image

This study investigated the variation in magnetic resonance characteristics of the fetal liver during a time of changing erythropoietic function. Echo-planar imaging was carried out in 25 normal pregnant women at 20 and 26 wk gestation. The signal intensity from regions of the fetal liver, background image, and maternal back muscle and the highest signal intensity from the maternal spinal cord were measured and compared with the signal intensity of amniotic fluid. Data are expressed as ratios, in arbitrary units (median pixel values; interquartile range shown in parentheses), and analyzed with the use of Wilcoxon’s signed-rank test. At 20 wk, the signal intensity ratio of liver to amniotic fluid was 0.309 (0.231–0.365). At 26 wk, the ratio was 0.544 (0.429–0.616). The change was highly significant ( P< 0.0001). No change in the signal intensity ratios of amniotic fluid compared with other measured parameters was noted. These data are consistent with known changes in fetal liver erythropoiesis occurring between 20 and 26 wk gestation and have potential use in early noninvasive physiological assessment of the fetus.
