OBJECTIVE: We aim to analyze each variable of FHR in high risk pregnancies, namely intrauterine growth restriction (IUGR) and pregnancy-induced hypertension (PIH) including chronic hypertensive vascular disease (CHVD), mild and severe preeclampsia to build an objective decision basis using correlation analysis. METHODS: The patients were divided into two groups (500 normal pregnancies and 500 high risk pregnancies related to IUGR, CHVD, mild and severe preeclampsia), and then subdivided into intrauterine pregnancy before 24 weeks, 25-39 weeks, and after 40 weeks. We compared the canonical correlation between each group using variables of FHR after nonstress test (NST). RESULTS: In high risk pregnancies, the linearity was 0.6-0.8 in intrauterine pregnancy before 24 weeks, 0.53-0.68 in 25-29 weeks, 0.50-0.60 in 30-34 weeks, 0.38-0.45 in 35-39 weeks and 0.42-0.55 in after 40 weeks. In normal pregnancies, the linearity was 0.44-0.52 in intrauterine pregnancy before 24 weeks, 0.38-0.45 in 25- 39 weeks which was stable, and there was no specific change in after 40 weeks. Before 32 weeks, canonical variates of FHR_D and FHR_I revealed highest (0.36, 0.47 respectively) in high risk pregnancy and fetal movement and signal loss was the most valuable factors in normal pregnancy. In between 33 to 37 weeks, fetal movement (0.40) and signal loss (0.48) were related most closely in high risk pregnancies and 0.34 and 0.49 respectively in normal pregnancies which show similar pattern. In contrast, FHR_D was most highly related to the duration of pregnancy and FHR_I to fetal movement (0.38) in high risk pregnancy. In normal pregnancies, fetal movement (0.40) and signal loss (0.52) showed the highest linearity. CONCLUSION: The pregnancy with intrauterine growth restriction and pregnancy induced hypertension has more linear relation and less complexity in each variable of FHR than the normal pregnancy group. The formal, functional underdevelopment of fetus may results in the increasement of the linear depedent relation in each variable of FHR in these type of high risk pregnancies.

The “Barker hypothesis” postulates that a number of organ structures and associated functions undergo programming during embryonic and fetal life, which determines the set point of physiological and metabolic responses that carry into adulthood. Hence, any stimulus or insult at a critical period of embryonic and fetal development can result in developmental adaptations that produce permanent structural, physiological and metabolic changes, thereby predisposing an individual to cardiovascular, metabolic and endocrine disease in adult life. This article will provide evidence linking these diseases to fetal undernutrition and an overview of previous studies in this area as well as current advances in understanding the mechanism and the role of the placenta in fetal programming.

Omental cyst is a rare disease and its accurate time and cause of outbreak has not been reported. This disease is known as can be afflicted with postnatally and in case of being afflicted with pre-natally the abdominal cavity and thoracic organ of fetus are oppressed due to fetal abdominal distention leading to fetal death caused by organ dysgenesis. No medical report has yet been published on congenital omental cyst of fetus. This study was conducted on a case of congenital omental cyst of fetus we have experienced in a mother with 16weeks of gestational period and the result is hereby reported along with literally documents.

Hemangiomas are common benign soft tissue tumors found in pediatrics. Knowledge of prenatal image findings for hemangiomas can be essential for ensuring optimal antepartum and postpartum care. In this study, we provide a report the MR findings of a congenital hemangioma in the posterior neck region, which was different from the pre and postnatal image findings as well as a literature review.

The theory on establishment of programmed in the fetal period and chronic diseases haven’t still given out anything clearly but in most of studies, they showed that there is a relation between fetal growing with cardiovascular diseases, hypertension and metabolic syndrome. Its establishment of programmed in fetal period doesn’t replace other risk factors but adding more the environmental factor to these diseases. Currently, the important of fetal nutrition and mother nutrition in pregnancy period are paid attention as well as other nutrition issue in the transition period.

We report a case of transient abnormal myelopoiesis in a Down syndrome fetus diagnosed at 28(+3) weeks of gestation that rapidly progressed to intrauterine death 10 days later. Fetal hepatosplenomegaly with cerebral ventriculomegaly, although not specific, may be a suggestive finding of Down syndrome with transient abnormal myelopoiesis. Prompt fetal blood sampling for liver function test and chromosomal analysis are mandatory for early detection and management.

BACKGROUNDRight dominant heart (RDH) in fetuses can occur with a number of cardiac as well as noncardiac anomalies. Analysis of the enlargement of the right cardiac chamber in the fetus remains a major challenge for sonographers and echocardiographers. The aim of this study was to report the experience with prenatal diagnosis of RDH in the fetuses over a 7-year period.

METHODSFetuses with prenatal diagnosis of RDH from July 2009 to July 2016 were evaluated in two different categories: according to the gestational age, Group I (n = 154, second trimester) and Group II (n = 298, third trimester); and according to the fetal echocardiography diagnosis, Group A (n = 452, abnormal cardiac structure) and Group B (n = 90, normal cardiac structure). Differences in categorical variables were assessed by Chi-square exact test and continuous variables were evaluated by independent Student's t-test or Mann-Whitney U-test depending on parametric or nonparametric nature of the data.

RESULTSOver a 7-year period, 452 fetuses were referred for the assessment of suspected RDH. Left-sided obstructive lesions were observed most frequently in the fetuses with RDH. When comparing Group I with Group II and Group A with Group B, the latter groups exhibited significant differences in the right/left ventricle (RV/LV) ratio (1.435 vs. 1.236, P = 0.002; 1.309 vs. 1.168, P = 0.047), RV width Z-score (1.626 vs. 1.104, P < 0.001; 1.553 vs. 0.814, P = 0.014), and above +2 cutoff percentages (14.3% vs. 22.5%; P = 0.038; 21.5% vs. 12.2%, P = 0.046). Multivariable logistic regression revealed no variables associated with perinatal survival.

CONCLUSIONSThe study demonstrates that RDH warrants careful attention to the possible presence of a structural cardiac anomaly, especially left-sided obstructive lesions. A diagnosis of RDH is best supported by a combination of the RV Z-score and RV/LV ratio. Most of the fetuses with RDH and structurally normal hearts had favorable outcomes.

Environmental contaminants are one of the important causal factors for development of various human diseases. In particular, the perinatal period is highly vulnerable to environmental toxicants and resultant dysregulation of fetal development can cause detrimental health outcomes potentially affecting life-long health. Perfluoroalkyl compounds (PFCs), emerging environmental pollutants, are man-made organic molecules, which are widely used in diverse industries and consumer products. PFCs are non-degradable and bioaccumulate in the environment. Importantly, PFCs can be found in cord blood and breast milk as well as in the general population. Due to their physicochemical properties and potential toxicity, many studies have evaluated the health effects of PFCs. This review summarizes the epidemiological and experimental studies addressing the association of PFCs with neurotoxicity and immunotoxicity. While the relationships between PFC levels and changes in neural and immune health are not yet conclusive, accumulative studies provide evidence for positive associations between PFC levels and the incidence of attention deficit hyperactivity disorder and reduced immune response to vaccination both in children and adults. In conclusion, PFCs have the potential to affect human health linked with neurological disorders and immunosuppressive responses. However, our understanding of the molecular mechanism of the effects of PFCs on human health is still in its infancy. Therefore, along with efforts to develop methods to reduce exposure to PFCs, studies on the mode of action of these chemicals are required in the near future.
