“…Teratogenesis infection such as genito-urinary infection may increase the neonatal death rate (Patrick, 1967), while stressful intrauterine conditions such as polyhydramnios was associated with adverse pregnancy outcomes and the risk of perinatal mortality (Sandlin et al, 2013). However, samples with the aforementioned disorders that may injure the fetal brain structures had been excluded (Waldorf and McAdams, 2013).…”

Development of the fetal hippocampal formation has been difficult to fully describe because of rapid changes in its shape during the fetal period. The aims of this study were to: (1) segment the fetal hippocampal formation using 7.0 T MR images from 41 specimens with gestational ages ranging from 14 to 22 weeks and (2) reveal the developmental course of the fetal hippocampal formation using volume and shape analyses. Differences in hemispheric volume were observed, with the right hippocampi being larger than the left. Absolute volume changes showed a linear increase, while relative volume changes demonstrated an inverted-U shape trend during this period. Together these exhibited a variable developmental rate among different regions of the fetal brain. Different sub-regional growth of the fetal hippocampal formation was specifically observed using shape analysis. The fetal hippocampal formation possessed a prominent medial–lateral bidirectional shape growth pattern during its rotation process. Our results provide additional insight into 3D hippocampal morphology in the assessment of fetal brain development and can be used as a reference for future hippocampal studies.

“…Polyhydramnios occurs in about 0.2-2% of pregnancies in the general population and is related in most of the cases to maternal diabetes, multiple pregnancies, fetal morphological anomalies and aneuploidies, along with other less common conditions [Hill et al, 1987;Kirkinen and Jouppila, 1987;Sandlin et al, 2013]. Breech presentation is seen in 3-4% of full term pregnancies [Hannah et al, 2000].…”

The aim of this study was to characterize the fetal phenotype of a cohort of individuals with confirmed diagnoses of Prader-Willi syndrome (PWS), a severe multi-system genetic disorder, diagnosed by a specific methylation test. We interviewed mothers of 106 individuals with PWS to obtain information about the pregnancy of their affected child. For 47 pregnancies of children younger than 10 years, we also reviewed the obstetric ultrasound and detailed obstetric history from medical records. We compared the PWS pregnancies with those of the sibling closest in age and with the general population. McNemars, Chi-square and Fisher exact tests were used for statistical analyses. Decreased fetal movements, small for gestational age (SGA), asymmetrical intrauterine growth (increased head/abdomen circumferences ratio) and polyhydramnios were found in 88%, 65%, 43%, and 34%, respectively (P < 0.001 vs. siblings and P < 0.0001 vs. the general population for all measurements). No severe morphological abnormalities were found. A combination of 2, 3, and 4 abnormalities was found in 27%, 29%, and 24% of pregnancies, respectively. Fourteen out of 15 umbilical artery Doppler studies were within the normal range (93%). The rare combination of asymmetrical intrauterine growth and polyhydramnios was found in 34% of PWS pregnancies (P < 0.0001 vs. the general population). Prenatal genetic screening for PWS by methylation testing is indicated when any combination of polyhydramnios, SGA or asymmetric intrauterine growth, with normal Doppler studies is present, particularly when asymmetrical intrauterine growth and polyhydramnios coexist.

“…Data from ultrasound examinations in the intervention group revealed normal amounts of amniotic fluid with respect to the gestational age, that is, >2 cm and <8 cm at the single deepest amniotic fluid pocket (SDP) [ 38 , 39 ] at baseline, before and after each WATSU treatment, and at follow-up (day 8) for all participants of the intervention group. Four participants with low baseline values (≤3.8 cm, mean 3.6 cm ± 0.1 cm) showed an average increase in amniotic fluid to 5.9 cm ± 1.5 cm on day 8.…”

Background. WATSU (WaterShiatsu) is a complementary therapeutic treatment method comprising passive stretches and massage techniques administered in 35°C warm water. Pregnant women claim safe methods to reduce pain, stress, and fatigue. Therefore, we conducted a pilot study evaluating the effects of WATSU on pregnancy-related complaints in third trimester pregnant women. Methods. Nine healthy pregnant women at gestational week ≥34 were included in an intervention group (receiving WATSU) and compared to eight women in a passive control group (receiving no treatment). WATSU was performed on days 1 and 4 of the study, accompanied by ultrasound examinations. Outcomes include physiological and psychometric as well as qualitative data. Participants in the control group completed questionnaires only. Results. WATSU was found to significantly lower participants' levels of stress and pain and to improve their mental health-related quality of life and mood. In comparison to the passive control group, participants in the intervention group reported reduction in perceived stress from day 1 to day 8 (P = 0.036, Cohen's f = 0.57). Qualitative data indicate that WATSU was appreciated as enjoyable and deeply relaxing. No negative side effects were reported. Conclusion. Our findings support the notion that WATSU yields therapeutic benefits for pregnant women and warrant further research. This study has been registered at ClinicalTrials.gov: NCT01708018.
