Purpose: To assess the outcomes of increased fetal nuchal translucency (NT), to aid in prenatal counseling and management in our practice. Materials and Methods: We retrospectively reviewed the medical records of patients who underwent first trimester fetal karyotyping using chorionic villi sampling (CVS) and second trimester level II sonography for a fetal NT thickness ${\geq}3.0mm$ between 11 weeks and 13 weeks 6 days' gestation, at Gyeongsang National University Hospital. Pediatric medical records and a telephone interview were used to follow-up live-born children. Exclusion criteria included incomplete data and CVS for other indications. Results: Seventy cases met the inclusion criteria (median NT thickness, 4.7 mm; range, 3.0-16.1 mm). Twenty-nine cases (41.4%) were aneuploid. The prevalence of chromosomal defects increased with NT thickness: NT 3.0-3.4 mm, 16.7%; NT 3.5-4.4 mm, 27.3%; NT 4.5-5.4 mm, 66.7%; NT 5.5-6.4 mm, 37.5%; NT ${\geq}6.5mm$, 62.5%. The most common karyotype abnormality was trisomy 18 (n=12), followed by trisomy 21 (n=9). In chromosomally normal fetuses (n=41), fetal death occurred in 2 cases (4.9%), and structural malformations were found in 11 cases (26.8%). In chromosomally and anatomically normal fetuses (n=28), one child had neurodevelopmental delay (3.6%). Twenty-eight infants who had a prenatal increased NT were alive and well at follow-up (40%). Conclusion: Outcomes of increased fetal NT might help inform prenatal counseling and management. The high prevalence of chromosomal defects associated with increased fetal NT implies that CVS should be performed in the first trimester, particularly considering the stress associated with an uncertain diagnosis.

BACKGROUND/OBJECTIVES: Little is known about the dietary patterns (DPs) of women during pregnancy. The present study aimed to identify the DPs of pregnant Malaysian women and their associations with socio-demographic, obstetric, and anthropometric characteristics. SUBJECTS AND METHODS: This prospective cohort study included 737 participants enrolled in Seremban Cohort Study between 2013 and 2015. Food consumption was assessed using a validated 126-food item semi-quantitative food frequency questionnaire (SFFQ) at four time-points, namely, pre-pregnancy and at each trimester (first, second, and third). Principal component analysis (PCA) was used to identify DPs. RESULTS: Three DPs were identified at each time point and designated DP 1-3 (pre-pregnancy), DP 4-6 (first trimester), DP 7-9 (second trimester) and DP 10-12 (third trimester). DP 1, 4, and 7 appeared to be more prudent diets, characterized by higher intakes of nuts, seeds & legumes, green leafy vegetables, other vegetables, eggs, fruits, and milk & dairy products. DP 2, 5, 8, and 11 had greater loadings of condiments & spices, sugar, spreads & creamer, though DP 2 had additional sweet foods, DP 5 and 8 had additional oils & fats, and DP 11 had additional tea & coffee, respectively. DP 3 and 6 were characterized by high protein (poultry, meat, processed, dairy, eggs, and fish), sugars (mainly as beverages and sweet foods), and energy (bread, cereal & cereal products, rice, noodles & pasta) intakes. DP 9 had additional fruits. However, DP 12 had greater loadings of energy foods (bread, cereal & cereal products, rice, noodles & pasta), sugars (mainly as beverages, and sweet foods), and good protein sources (eggs, nuts, seeds & legumes). Malays were more likely to have lower adherence (LA) for DP 1 and 10 than non-Malays. DP 2, 8, and 11 were more prevalent among Malays than non-Malays. Women with a higher education were more likely to have LA for DP 10, and women with a greater waist circumference at first prenatal visit were more likely to show LA for DP 11. CONCLUSIONS: DPs observed in the present study were substantially different from those reported in Western populations. Information concerning associations between ethnicity, waist circumference and education with specific DPs before and throughout pregnancy could facilitate efforts to promote healthy dietary behavior and the overall health and well-being of pregnant women.

About 15% to 20% of all clinically recognized pregnancies result in spontaneous abortion or miscarriage, and chromosomal anomalies can be identified in up to 50% of first trimester miscarriages. Chromosomal microarray analysis (CMA) is currently considered first-tier testing for detecting fetal chromosomal abnormalities and is supported by the absence of cell culture failure or erroneous results due to cell contamination in pregnancy loss. Triploidy is a lethal chromosome number abnormality characterized by an extra haploid set of chromosomes. Triploidy is one of the most common chromosomal aberrations in first trimester spontaneous abortions. Here, we report two cases of triploidy abortion that were not detected using array comparative genomic hybridization-based CMA. The aim of this report was to remind clinicians of the limitations of chromosomal testing and the misdiagnosis that can result from biased test selection.

This survey was carried out to investigate the nutritional status of 102 rural pregnant women after the 2nd trimester and the effect of pregnant nutritional status on newborn infant's anthropometric measurements. 102 rural pregant women's age was distributed 20 to 34. Pregnant height and prepregnant weight were 157.7$\pm$3.2cm and 50.7$\pm$5.4kg, respectively, which were similar to Korean standard, and pregnant weight gain per week after the 2nd trimester was 0.35$\pm$0.13kg, which was showed normal weight gain. Pregnant blood pressure were 112.6$\pm$12.7mmHg (systolic pressure) and 71.8$\pm$10.6(diastolic pressure), and energy and protein intake were 83.8$\pm$34.3% and 72.2$\pm$24.2% of RDA, respectively. Hemoglobin and blood protein level of 17 pregnant women who selected among total pregnant women were 11.8$\pm$1.0g / dl, 6.5$\pm$0.9g / dl, respectively. Height, weight, and head circumference of 17 newborn infants who delivered from 17 pregnant women were 50.1$\pm$1.9cm, 3.4$\pm$0.6kg, and 31.4$\pm$1.2cm, respectively, which were similar to Korean standard. Infant height, weight, and head circumference at birth were significantly correlated with pregnant higher than dietary intakes and weight gain per week during midpregnancy.

Periodontitis is a chronic infectious disease that leads to the destruction, one of the major cause of tooth loss in human. Osteoclast Differentiation Factor(ODF), also called as Receptor activator of NF-${\kappa}B$ ligand(RANKL), a surface-associated ligand on bone marrow stromal cells and osteoblasts, activates its cognate receptor RANK on osteoclast progenitor cells, which leads to differentiation of these mononucleated precursor cells. Osteoprotegerin(OPG), a decoy receptor, is released from stromal cells and osteoblasts to inhibit the interaction between RANKL and RANK. The experiment for the effect of pregnancy on gingival health showed greater gingival inflammation and edema during pregnancy, despite similar plaque index. There should be many factors affecting the periodontal health in pregnancy. In this experiment, we examined the direct effects of sex hormones(estrogen and progesterone) on the ODF/OPG expression in human gingival fibroblasts and periodontal ligament cells at the serum concentration of pregnancy. The ratio was high in the 1st trimester of pregnancy by estrogen and in the late 2nd trimester by progesterone. Therefore, the local periodontal destruction might be accelerated by these hormonal effect on the periodontal cells.

Iron deficiency anemia in pregnant women has been of great concern because of its negative effects on the outcomes of pregnancy. Much of evidence has shown that there are associations between pregnancy outcomes and maternal iron status. Maternal iron status might affect pregnancy outcomes through the iron status of the cord blood. In this study, we divided 91 subjects into two groups : the anemic and the normal groups. The groups were classified according to their hemoglobin(Hb) and hematocrit(Hct) values of the maternal blood in the third trimester of the pregnancies. We determined the parameters for the iron status of the cord blood and then analyzed the correlations between these parameters and the pregnancy outcomes. Mothers in the anemic group had a significantly higher parity number and a lower dietary score as well as a shorter duration of iron supplements consumed compared to those in the normal group. Maternal Hb values in the third trimester had positive correlations with the infant's head and chest circumferences, and the Hct values related positively to the infant's chest circumferences. On the other hand, Hb concentrations of the cord blood had positive correlations with the infant's height and head and chest circumferences. The Hct values of the cord blood had positive correlations with gestational periods and the cord lengths. These results suggest that the maternal iron status might influence fetal development through the iron status of the cord blood.

In this case report, I discussed the diagnosis and treatment of two pregnant women with temporomandibular disorders(TMD) who visited the Department of Oral Medicine, PNUH. Also, I reviewed some investigations of diagnosis and treatment of TMD in pregnant women. The obtained results were as follows; 1. No single X-ray diagnostic procedure for TMD results in radiation dose that threatens the well-being of the developing embryo and fetus. 2. Most non-steroidal anti-inflammatory drugs(NSAIDs) have commonly used because these drugs are considered to be nonteratogenic, but these agents are not recommended for routine use after 3rd trimester. 3. Electro-acupuncture stimulation therapy(EAST) is contraindicated for 1st trimester, and ultrasonic deep heat therapy, microwave deep heat therapy, low level laser therapy, myo-monitor are not contraindicated for pregnant women but clinician must consider some risk of adverse fetal effects. 4. The occlusal stabilization splint may be used for pregnant women, if it is fabricated indirectly. 5. Surgical treatment is contraindicated for pregnant women.

For the comparative study of protein patterns of the sera of pregnant women, the protein in sera of normal male subjects, non-pregnant women, pregnant women and women delivered of children were analyzed by using the methods of SDS/polyacrylamide gel electrophoresis, two-dimensional electrophoresis and amino acid analysis. The results were as follows: 1. When the protein patterns of sera in normal male ranging from 10, 000 to 110, 000 daltons were compared to non-pregnant women by SDS/polyacrylamide gel electrohporesis, their protein patterns were same each other numerically but bands 3(22, 000 dalton) and 6(39, 000) were less in male than in non-pregnant women quantitatively. When the protein patterns in the pregnant women in which serum were collected two week intervals were compared with non-pregnant women, there was increased or decreased in several bands quantitavely. The protein patterns of sera in pregnant women were compared with those of non-pregnant women; band 3(22, 000) showed similar patterns each other until the 16th week but the quantity of protein was decreased continously from the 18th week to the third trimester of pregnancy. Contary, bands 4(24, 000), 9(69, 000), 10(70, 000), 12(80, 000), 14(86, 000), 15(91, 000) and 16(94, 000) were gradually increased in quantity from the begining of gestation, and band 7(51, 000) was increased until the 32th week of gestation only but somewhat decreased after this time. The quantities of bands 12(80, 000), 15(91, 000) and 16(94, 000) were relatively increased when the protein patterns of delivered women were compared with those of the third trimester of pregnancy. Women who were dilivered female children showed more increase in bands 4(24, 000), 7(51, 000) and 10(70, 000)than one who were delivered male chilren. 2. When the protein patterns of sera in normal males were compared with those of nonpregnant women by two-dimensional electrophoresis, three spots of spot a group were not appeared in the males and the spot c group in the males was less than in the non-pregnant women. In the pregnant women, albumin was significantly decreased during the 10-12 week of gestation but recovered after these times. And spot f(70, 000) was decreased in the 10th week of gestation but increased from this time. 3. Glutamic acid, lysine, aspartic acid, leucine and valine in pregnant women were large in quantity while methionine, isoleucine and glycine were small in quantity by amino acid analysis. The total amino acids were increased remarkably in the second trimester of pregnancy but began to decrease in the third trimester of pregnancy. As mentioned, this present paper deat with that proteins which consist of maternal serum were increased with specific period in pregnancy and that the change of characteristic protein patterns were identified in the serum protein of each trimester in the pregnant women. And furthermore, the study should be preformed for the sex-identification of a fetus in the early pregnancy.
