Abstract
The number of women with congenital heart disease (CHD) reaching reproductive age has been increasing. Many women with CHDs are desirous of pregnancy, but they face issues regarding preconception, antepartum, and postpartum management. On the other hand, the fetal diagnosis of CHD has improved with advances in the technique and equipment for fetal echocardiography. Recently, experiences with fetal intervention have been reported in patients with severe CHD, such as critical aortic stenosis. Nevertheless, some types of CHD are challenge to diagnose prenatally, resulting in adverse outcomes. Medical care is part of the transitional care for women and fetuses with CHD during the perinatal period. Pre-conceptional and prenatal counseling play an important role in transitional care. Sex and reproductive education need to be performed as early as possible. We herein review the current status, important issues to be resolved, and the future of maternal and fetal CHD to relevant caregivers.

Abstract
BACKGROUND We aimed to explore the relationship between temporal right heart growth and long-term outcomes in patients with pulmonary atresia with intact ventricular septum (PA/IVS) who underwent balloon pulmonary valvulopalsty (BPV). METHODS Echocardiography was performed to measure the pulmonary valve diameter (PVD), the right atrial end-systolic area (RAA), and the right ventricular end-diastolic area (RVA) before BPV, 1 and 5 years after BPV. The primary and secondary endpoints were to explore temporal changes in the right heart structures and to determine echocardiographic parameters related to late adverse events (LAEs). RESULTS In 31 patients, PVD significantly increased after BPV, whereas TVD remained unchanged throughout the follow-up period of 9.1 (5.7-12.0) years. After BPV, RAA temporally decreased, whereas RVA significantly increased. There were six LAEs (19%); arrhythmias in two, heart failure in one, reintervention of the right ventricular outflow tract in one, and reintervention for residual cyanosis in two. The rate of freedom from LAEs at 5 and 10 years were 92% and 82%, respectively. RAA temporally decreased in patients without LAEs (P<0.01); however, RAA remained unchanged throughout the period in patients with LAEs (P=0.16). Moderate or severe pulmonary regurgitation (PR) (hazard ratio [HR], 23.0; 95% confidence interval [CI], 1.3-385; P=0.03) and the ratio of RVA /RAA at 1 year after BPV (HR, 6.3×10-11; 95%CI, 2.1×10-20-0.19; P=0.03) were independent risk factors for LAEs. CONCLUSIONS Disproportional right heart growth was observed in patients with PA/IVS after BPV. PR and increased RAA are crucial in identifying the burden of LAEs among them.

Abstract
OBJECTIVE To clarify the frequency and characteristics of discrepant outcomes of intravenous immunoglobulin (IVIG) between fever and coronary artery aneurysms (CAAs) in patients with Kawasaki disease. STUDY DESIGN This study included 325 patients who responded to oral aspirin and IVIG alone. The main outcome was CAA 4 weeks after disease onset. CAA was defined as ≥2.5 of maximum z score (Zmax) representing the highest value of 4 coronary artery branches. Immunoglobulin dosage and sequential changes in Zmax were reviewed to investigate the effects on fever and timing of CAA development. Logistic regression analyses with receiver operating characteristic curves using clinical and laboratory variables including the initial Zmax were performed to identify predictors of CAA at 4 weeks. RESULTS CAAs were either persistent or appeared de novo 4 weeks after diagnosis in 13 of 325 patients who responded to a single or repeated IVIG. Four single-dose IVIG-responders developed CAA although they had pretreatment Zmax of <2.0. The 2 single-dose IVIG responders with the greatest pretreatment Zmax (>4.5) developed persistent CAA. Receiver operating characteristic analysis demonstrated Zmax of 2.57 as the cut-off for predicting CAA. Multivariable analyses identified >2.5 Zmax (OR 9.08, 95% CI 1.26-65.3, P = .028, 50% sensitivity, 91% specificity) as the sole risk factor for CAA at 4 weeks in single-dose IVIG responders. CONCLUSIONS Delayed development and persistence of CAA in single-dose IVIG responders indicate that some factors other than those responsible for systemic inflammation may contribute to vasculitis in CAA. Baseline Zmax 2.5 aids in predicting CAAs.

Abstract
Abstract
Introduction
Short-chain fatty acids are one of the gut microbial metabolites that may influence host physiology. We previously reported that gut dysbiosis was associated with heart failure, and that the proportions of butyrate-producing bacteria diminished prominently in the gut of patients with heart failure.
Purpose
We investigated the molecular mechanism of butyrate and investigated the protective mechanism against heart failure.
Methods
We searched for G protein-coupled receptors for short-chain fatty acids using single-cell transcriptome analysis of cardiomyocytes and non-cardiomyocytes isolated from murine hearts. In addition, we examined the effects of butyrate on endothelin-1 (ET1) or isoproterenol-induced hypertrophic responses and histone deacetylase (HDAC) activities in cultured neonatal rat cardiomyocytes.
Results
Single-cell transcriptome analysis and co-expression network analysis revealed that G protein-coupled receptors for short-chain fatty acid receptors were not expressed in cardiomyocytes and that Olfr78 was expressed in vascular smooth muscle cells in the heart. Treatment with butyrate inhibited ET1-induced hypertrophic growth and up-regulation of the genes such as Nppa, Acta1, and Myh7 in cultured rat neonatal cardiomyocytes. Moreover, butyrate increased the acetylation levels of histone H3, indicating that butyrate has an inhibitory effect on HDAC in cardiomyocytes. In addition, treatment with butyrate caused up-regulation of Inpp5f, encoding inositol polyphosphate-5-phosphatase f, which was associated with a significant decrease in the phosphorylation levels of Akt. These results suggest that butyrate may act as HDAC inhibitor to increase Inpp5f gene expression, leading to the activation of Akt-glycogen synthase kinase 3beta (Gsk3beta) pathway, and thereby protect against hypertrophic responses.
Conclusion
There was no known GPCR for short-chain fatty acid expressed in cardiomyocytes. However, butyrate suppressed cardiomyocyte hypertrophy through epigenetic modification of gene expression. Our results may uncover a potential role of the dysbiosis of intestinal microbiota in the pathogenesis of cardiac hypertrophy and failure.

Abstract
OBJECTIVE/BACKGROUND This study aimed to clarify the relationship between migraine-like headache and ventriculo-arterial coupling after transcatheter closure of the atrial septal defect in children. We hypothesized that migraine headache after defect closure would be related to an abnormal hemodynamic response against an increased left ventricular filling. DESIGN A retrospective cohort study. METHODS We calculated the end-ventricular systolic elastance (Ees), effective arterial elastance (Ea), and ventricular energy efficiency approximated based on echocardiography before and after defect closure, and compared these parameters between the subjects with and without headache after defect closure. RESULTS A total of 167 subjects were studied. Age at the procedure, defect diameter, and pulmonary to systemic blood flow ratio were 11 (9-17) years, 12.8 (9.2-16.0) mm, and 1.8 (1.6-2.3), respectively. We identified 47 (28%) subjects with migraine headache after defect closure. Although there was no significant difference in the Ees, Ea, and ventricular energy efficiency before defect closure between the groups, the Ees (4.0 [3.4-4.9] vs 4.8 [3.7-6.1], P = .014) and ventricular energy efficiency (0.79 [0.76-0.82] vs 0.83 [0.79-0.85], P = .001) after defect closure in subjects with headache were significantly lower than those in subjects without headache. Migraine headache after defect closure was significantly associated with age (odds ratio: 0.97, 95% confidential interval: 0.94-1.00, P = .036) and a decrease in the ventricular energy efficiency after defect closure (odds ratio: 6.42, 95% confidential interval: 2.76-14.90, P < .001). CONCLUSION A loss of ventricular energy efficiency was common in pediatric subjects with migraine-like headache after transcatheter closure of the atrial septal defect, which suggested that the left ventricular function maladaptation was related to headache development after defect closure. We advocate that an impaired ventriculo-arterial coupling may be one of the mechanisms for developing attacks in not only this population but also in other patients with migraine.

Abstract
We describe our experience of high-intensity focused ultrasound (HIFU) for fetal therapy in twin-reversed arterial perfusion (TRAP) sequence. Six pregnant women underwent HIFU therapy, five before 16 weeks and one at 26 weeks. Two types of HIFU system were used: the first-generation system, which comprised a biaxial transducer and continuous exposure pattern, and the second-generation system, which comprised a coaxial transducer and sequential exposure pattern. The first-generation apparatus was used in four cases and the second-generation apparatus was used in two. In three cases, occlusion of the blood vessels mediating flow to the acardiac twin was achieved by HIFU. Two cases experienced intrauterine fetal death despite vessel occlusion. The total survival rate of pump fetuses 2 years after HIFU was 67% and the efficiency rate (the proportion of cases with occlusion or reduced blood flow on ultrasound after HIFU) was 83%. After more than 2 years of follow-up, the surviving infants had no severe clinical complications and no postnatal developmental problems. There was no significant difference in survival rate compared with TRAP cases managed expectantly. Given that complete occlusion of the blood vessels was not achieved in half of the cases, we could not show that HIFU therapy is superior to other treatments. However, HIFU can reduce the cardiac load of the pump fetus and, as it does not require uterine puncture for fetal therapy, there were no fatal complications, such as bleeding, rupture of membranes or infection. Thus, HIFU therapy may represent a less-invasive treatment for TRAP sequence in early pregnancy. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
We present a 16-year-old male patient with hypoplastic left heart syndrome who developed protein-losing enteropathy (PLE) and plastic bronchitis (PB) after a Fontan operation. He received medical therapies, including albumin infusion, unfractionated heparin, and high-dose anti-aldosterone therapy but could not obtain clinical relief. Biphasic cuirass ventilation (BCV) led to expectoration of bronchial casts and prompt resolution of PB. Notably, clinical symptoms related to PLE were dramatically improved after starting BCV. A brief period of BCV increased stroke volume from 26±1.4 to 39±4.0 mL. This case suggests that BCV could be an effective treatment for PLE in patients with failing Fontan circulation.

Abstract
BACKGROUND Preterm birth is known to be associated with an increased risk of pulmonary arterial hypertension, although how preterm birth influences pulmonary hemodynamics has not been fully understood. Pulmonary arterial resistance (Rp) and compliance (Cp) are important factors to assess the pulmonary circulation. The purpose of this study is to clarify the relationship between Rp and Cp in preterm infants. METHODS We performed cardiac catheterization in 96 infants (50 males) with ventricular septal defect, and compared pulmonary hemodynamic parameters including Rp and Cp between preterm and full-term infants. RESULTS Thirteen infants were preterm. There were no significant differences in sex, age, preoperative pulmonary arterial pressure, preoperative pulmonary-to-systemic flow ratio, and preoperative Rp between the 2 groups. However, preoperative Cp and resistor-capacitor (RC) time in preterm infants were significantly lower than those in full-term infants (2.1 vs 2.8mL/mmHg/m2 and 0.31 vs 0.36s, respectively; p<0.05 and p<0.01, respectively). Postoperative systolic and mean pulmonary arterial pressures were higher in preterm infants than those in full-term infants (29 vs 25mmHg and 18 vs 14mmHg, respectively; both p<0.01). It was also observed that postoperative Cp was lower in preterm infants, although postoperative Rp remained unchanged. CONCLUSIONS We demonstrated that preterm infants with pulmonary arterial hypertension had lower Cp than full-term infants, causing a modest increase in pulmonary arterial pressure. It is important to consider the unique pulmonary vasculature characterized by lower Cp, when managing preterm infants with congenital heart disease.

Abstract
A new type of electronic interaction which couples two angular momenta, i.e. the angular momentum of a localized 4f system (J) and an orbital angular momentum generated in a cyclic π conjugated system by irradiation with a circularly-polarized light, has been identified in a lanthanide single molecule magnet.

Abstract
Retroperitoneal leiomyosarcoma is a relatively rare and aggressive tumor. Because of its rarity, it is difficult to arrive at a definite diagnosis preoperatively and to design an effective strategy. Here the authors report a case of peritoneal leiomyosarcoma in which diagnosis was difficult because the clinical course resembled that of ovarian cancer. A 77-year-old woman diagnosed with ovarian cancer underwent laparotomy. The excised tumor contained a necrotic polypoid mass that histologically displayed the features of leiomyosarcoma. The patient received adjuvant chemotherapy with a combination of gemcitabine and docetaxel but died two months after surgery owing to the aggressive behavior of the tumor. Because the preoperative diagnosis in this case was ovarian cancer, arriving at a treatment strategy assuming peritoneal leiomyosarcoma was difficult. If complete surgical resection of tumor is not performed, as in the present case, the prognosis can be extremely poor.

Abstract
The aim of this analysis was to investigate the onset time and significance of maximum volume of polyhydraminios and whether the tter was associated with causes. This was a retrospective cohort study between 2012 and 2014. A total number of 68 singleton pregancies were analyzed. Gestational age at onset of polyhydramnios was 30.0 ± 2.8 (25-36) weeks in maternal factor, 30.0 ± 3.5 (25- 7) weeks in fetal factor, and 32.3 ± 2.0 (27-37) weeks in idiopathic factor. Median of maximum amniotic fluid index (AFI) was gnificantly late onset in idiopathic factor. Diabetes, gestational or pre-existing, was present in all of women (ten cases) in maternal facror. Higher AFI was found to be associated with an increased frequency of prenatally detected congenital anomalies. Abnormal fetal kary- type noted in 18/45 (40%) cases of polyhydramnios. Polyhydramnios diagnosed on ultrasound requires further maternal and fetal iagnostic tests.

Abstract
This was a retrospective cohort study between 2002 and 2011. A total number of 150 singleton pregnancies with preterm premature rupture of membranes (PROM) (before 34 weeks) were analyzed. Histological chorioamnionitis (Blanc grade III) was significantly increased over three days from onset of premature rupture of membranes. The positive relationship was strengthened (odds ratios, 3.5; 95% confidence intervals, 1.5-5.2) over three days from onset of preterm PROM. PROM is a risk factor important for histological chorioamnionitis. To avoid neonatal infection, early termination is recommended in preterm PROM patients.

Abstract
The authors here report a 54-year-old (gravida 0, para 0), who claimed to have had her menarche at age 13 and menopause at 52 years. Two months prior to presentation, the subject first noticed a hard but elastic fist-sized mass in the left inguinal region that gradually grew, causing pressure-related pain. Although the external genitalia appeared female, the vagina was short and blind-ending, and no uterus or ovaries were identified on transvaginal ultrasound. Chromosome banding results (G-band method) showed 46XY. Laparoscopy revealed no traces of a vestigial uterus or ovaries; thus, based on the appearance of the external genitalia, a diagnosis of testicular feminization syndrome was made. Pathological testing of the palpable mass led to a diagnosis of seminoma with Leydig cell hyperplasia. Thus, in this case, the development of a seminoma in an undescended testis led to the detection of testicular feminization syndrome.

Abstract
PURPOSE OF INVESTIGATION This study aimed to estimate the effectiveness of hysteroscopic myomectomy for symptomatic submucous uterine fibroids and to identify prognostic factors for persistent or recurrent symptoms. MATERIALS AND METHODS A total of 237 patients who underwent hysteroscopic myomectomy were divided into three groups according to the classification of the European Society for Gynaecological Endoscopy: Type 0 (n=116), Type I (n=97), and Type II (n=24). Medical records and videotape records of all patients were retrospectively reviewed. RESULTS Improvement of symptoms was achieved in 100% of Types 0 and I, and 66.7% of Type II. The five-year cumulative symptom-free rates after hysteroscopic myomectomy were 96.7% ± 1.9%, 87.8% 6.7%, and 44.5% ± 12.7% in Types 0, I, and II, respectively. The mean symptom-free periods were 46.2 ± 2.6, 47.7 ± 2.7, and 24.7 ± 6.3 months in Types 0, I, and II, respectively. Logistic regression analysis showed that co-existence of other myomas and Type II were independent prognostic factors for recurrence of symptoms. CONCLUSION Type I fibroids are a good indication for hysteroscopic myomectomy. In Type II, some patients feel that their symptoms improve, but this curative effect could be temporary.

Abstract
The present authors analyzed patients' backgrounds and pre-surgical findings to clarify the risk factors of rupture of fallopian tubal pregnancy. The surgical findings 113 cases were clearly diagnosed as fallopian tubal pregnancy with or without rupture. Twenty-six cases of fallopian tubal pregnancy were ruptured and 87 cases were not ruptured at the time of operation. The risk factors of fallopian tubal rupture were assessed by Chi-square for independence test and multiple regression analysis. Obesity (BMI over 26), prior birth history, social welfare entitlement, ultrasonography findings of fetal heart movement, and pre-surgical serum beta-hCG level more than 3,000 mIU/ml patient were significantly higher risk in fallopian tubal rupture. Fertility treatment patient were at significantly lower risk for fallopian tubal rupture. Higher beta-hCG levels, especially >3,000 mIU/ml is associated with increased risk of fallopian tubal rupture in ectopic pregnancy.

Abstract
Zingiber zerumbet contained the typically essential oils. The research aims to evaluate the effect Z. zerumbet essential oil and zerumbone inhlation on rats body weight, food consumption, parasympathetic nerve activity and brown adipose tissue temperature. The essential oils of Z. zerumbet was isolated from the rhizome of Z. zerumbet. The component in the oil and zerumbone structure was determined by gas chromatography-mass spectroscopy. The structure of zerumbone crystal was determined by nuclear magnetic resonance spectroscopy. The Sprague dawley male adult rats were divided into 4 groups namely Normal Diet (ND) group, High Fat Diet (HFD) group, HFD inhaled Z. zerumbet essential oils group and HFD inhaled zerumbone group. The results showed that inhalation of Z. zerumbet essential oils and zerumbone increased the food consumption as well as increased the body weight. The increasing body weight of rats which inhaled Z. zerumbet essential oils and zerumbone is by decreasing the sympathetic nerve activity. In conclusion, inhaling Z. zerumbet essential oils and zerumbone as the major component of the oils increased the weight gain.

Abstract
High-intensity focused ultrasound (HIFU) has excellent potential as a non-invasive therapeutic tool in various fields of medicine. We present a case of twin reversed arterial perfusion sequence, in which non-invasive blood flow occlusion in the acardiac fetus was successfully achieved by means of HIFU exposure from outside the maternal abdomen. HIFU was applied to blood vessels of the acardiac fetus at the point at which the umbilical cord entered the body in a series of four procedures at 3-day intervals starting at 13 weeks' gestation, and in a final procedure with higher power at 17 weeks. The HIFU intensity was set at approximately 2300 W/cm(2) for the initial series of procedures and at 4600 W/cm(2) for the final procedure, with exposure periods of 10 s. As color Doppler examination revealed absence of blood flow to the acardiac fetus after the second round of HIFU exposure, we concluded that complete occlusion of target vessels had been achieved. Delivery was by Cesarean section at 37 weeks' gestation. A male neonate (the pump fetus) was born weighing 1903 g with Apgar scores of 8 and 9 at 1 and 5 min, respectively. At the time of writing, the baby was healthy and growing normally, with the exception of congenital pseudarthrosis.

Abstract
Twin reversed arterial perfusion (TRAP) sequence is a serious complication of monochorionic twin pregnancies, in which arterioarterial anastomoses allow blood flow from a 'pump' fetus to an acardiac fetus via reversed flow in the latter's umbilical artery. Several trial treatments for TRAP sequence have been reported, but all of these have been invasive. We present a case of TRAP sequence in which high-intensity focused ultrasound (HIFU) was applied to the umbilical artery of the anomalous twin at 26 weeks as a non-invasive fetal therapy. The HIFU intensity was set at approximately 2300 W/cm(2) with exposure periods of 10 s. Color Doppler ultrasound showed a decrease in blood supply to the anomalous twin, although complete occlusion of the targeted vessel was not achieved. Delivery was by Cesarean section at 29 weeks' gestation and the pump twin survived, without severe clinical complications at 6 months.

Abstract
OBJECTIVES To investigate whether umbilical venous velocity and venous velocity pulsation are associated with umbilical vein diameter, umbilical ring diameter and umbilical cord coiling index at midgestation. METHODS Two hundred and eighty pregnant women were enrolled in the study at between 18 and 24 weeks of gestation. The diameter of the umbilical cord and internal diameter of the umbilical vein in a free loop and at the ring, and the umbilical coiling index, were measured using ultrasonography. Umbilical venous velocities were measured by Doppler ultrasonography at the umbilical ring and a free loop of the cord. RESULTS All variables were successfully measured in 92% of the patients. There were negative correlations between the diameters of the umbilical ring and of the umbilical vein at the ring and the venous velocity at the umbilical ring. The venous velocity at the umbilical ring was significantly higher and the umbilical ring diameter was significantly lower in fetuses with umbilical venous pulsation at the free loop. Significant correlations were observed between the venous velocity and amplitude of pulsation. Venous pulsations at the free loop were frequently observed in fetuses with a hypercoiled cord. CONCLUSION High venous velocity and increased venous pulsation at the umbilical ring may be associated with umbilical cord constriction.

Abstract
OBJECTIVES To investigate whether maternal history and ultrasound findings can be predictors for massive hemorrhage during Cesarean section in patients with placenta previa and adherence of the placenta. METHODS We reviewed 127 singleton pregnancies with placenta previa. Maternal history, antenatal ultrasound findings of the placenta, including location, presence of placental lacunae, lack of a clear zone, presence of sponge-like findings of the cervix and presence of a marginal sinus in cases of placenta previa were reviewed retrospectively, and their association with amount of bleeding during Cesarean section was analyzed. RESULTS Logistic regression analysis revealed that advanced maternal age (odds ratio (OR), 5.4; 95% CI, 1.8-16.4), previous Cesarean section (OR, 20.4; 95% CI, 4.0-105.2) and sponge-like findings in the cervix (OR, 5.6; 95% CI, 1.8-17.0) were associated with massive bleeding (> 2500 mL). Placental adherence occurred in five cases and was more frequent in cases where the placenta was located at the site of the scar of a previous Cesarean section (OR, 123.1; 95% CI, 4.5-3395.2) and where there was lack of a clear zone (OR, 48.0; 95% CI, 3.8-604.7). CONCLUSIONS Advanced maternal age, previous Cesarean section and presence of sponge-like findings in the cervix are risk factors for massive bleeding during Cesarean section in cases of placenta previa, regardless of whether placental adherence is present. Placental location on the scar of a previous Cesarean section and lack of a clear zone are risk factors for placental adherence. When these findings are identified preoperatively, management should be tailored accordingly.

Abstract
OBJECTIVES To investigate the application of high-intensity focused ultrasound (HIFU) for fetal umbilical artery blood flow occlusion in a rabbit model. METHODS A prototype HIFU transducer in combination with an imaging probe with Doppler capability was constructed. Using this transducer, HIFU was applied at 1.4, 2.75 or 5.5 kW/cm(2) through the maternal abdominal skin to the fetal intra-abdominal umbilical arteries of four time-mated Japanese White rabbits (11 fetuses) on gestational day 25. Courses of 5-s HIFU exposure were performed until cessation of umbilical blood flow and cardiac arrest were confirmed by Doppler ultrasonography. Fetal necropsy was performed and exposed lesions were assessed by microscopic histological analysis. RESULTS The mean diameter of the fetal umbilical artery was 0.6 +/- 0.2 mm and the mean peak systolic velocity of arterial blood flow was 44.7 +/- 18.5 cm/s. When HIFU was applied at 5.5 kW/cm(2), blood flow was completely occluded within 15 courses. HIFU exposure brought about vacuolar degeneration and destruction of elastic fibers in the tunica media of the artery. CONCLUSIONS HIFU can be used to occlude umbilical artery blood flow in fetal rabbits.

Abstract
OBJECTIVES To assess the feasibility of detecting the cord insertion site during the late first trimester, and to investigate the possible association between perinatal complications and a cord insertion in the lower third of the uterus in the first trimester. METHODS This was a prospective cohort study in which the positional relationship between the uterus and the cord insertion site was examined using gray-scale transvaginal sonography at 9-11 weeks of gestation. The distance between the internal os and the fundus was divided equally into three parts. Cord insertions located in the upper or middle thirds were defined as normal (controls), and those located in the lower third were defined as cases, regardless of their relationship to the chorion villosum. Third-trimester sonography and pathological examination of the placenta and cord at delivery were performed to check for placental/cord abnormalities. The univariate association between the location of the cord insertion in the first trimester and placental and umbilical cord abnormalities and perinatal complications was assessed. RESULTS The cord insertion site was identified in 318/340 (93.5%) cases at 9-11 weeks of gestation and it was in the lower third of the uterus in 35 (11.0%) cases. Of these 35, the cord insertion was found at delivery to be low in nine cases (26%) and the placenta was low-lying at delivery in eight (23%). None of the 283 cases with a normal cord insertion in the first trimester was found to have a low-lying placenta at delivery (P < 0.0001). Ten (29%) of the cases with a low cord insertion and four (1.4%) with a normal cord insertion in the first trimester had a velamentous or marginal cord insertion at delivery (P < 0.0001). At delivery, five (14%) of the low cord insertion cases and four (1.4%) of the normal cord insertion cases (P < 0.0001) had some form of placental malformation, including accessory placenta and infarction of the placenta. An emergency Cesarean section was performed in four (11%) and six (2.1%) of the low and normal cord insertion cases, respectively (P = 0.003). CONCLUSION Developmental abnormalities of the placenta and umbilical cord occur frequently in cases in which the cord insertion is in the lower third of the uterus in the first trimester. We suggest that screening for the cord insertion site at 9-11 weeks of gestation may have clinical significance for predicting abnormalities of the cord and the placenta at delivery.

Abstract
OBJECTIVES To evaluate the accuracy of sonographic identification of the site of umbilical cord insertion (CI) at 18-20 weeks of gestation, to compare the sensitivities for detection of a velamentous cord insertion (VCI) secondary to a CI into the anterior, posterior or fundal wall, and to compare the intrapartum complications secondary to VCI into the upper, middle or lower third of the uterus. METHODS As part of the routine ultrasound scan at 18-20 weeks' gestation we evaluated abnormal CI (VCI and marginal CI) and the location of the CI in the uterus in 3446 pregnancies. In cases of abnormal CI, the location of the CI was further classified as being in the upper, middle or lower third of the uterus. After delivery, the placenta and the umbilical cord were examined and intrapartum complications were compared with the location of the CI. RESULTS The values for antenatal detection of VCI were: sensitivity, 25 of 40 (62.5%); positive predictive value, 25 of 25 (100%); and negative predictive value, 3406 of 3421 (99.6%). The sensitivity for cases in which the CI was located on the anterior wall was 12 of 13 (92.3%); when it was located on the posterior wall, the sensitivity was 11 of 22 (50.0%); and when it was fundal the sensitivity was 2 of 5 (40.0%). Variable decelerations were frequently observed with a VCI. In lower VCI cases, non-reassuring fetal heart rate patterns and emergency Cesarean sections occurred with a higher frequency than in cases with upper or middle VCI (P < 0.01). After delivery, the length of the aberrant vessels in cases of VCI by pathologic examination was 3.9 +/- 3.3 cm in the upper third, 4.7 +/- 4.6 cm in the middle third, and 10.6 +/- 6.8 cm in the lower third; thus, the aberrant vessel length was significantly greater when the CI was in the lower third of the uterus (P = 0.024). CONCLUSION We have demonstrated that VCI with a lower CI site and with longer aberrant vessels is associated with various intrapartum complications. This finding has the potential for improving perinatal outcome.

Abstract
OBJECTIVES To examine intrapartum fetal heart rate (FHR) patterns in the presence of velamentous cord insertion (VCI). METHODS The site of cord insertion was determined in 1460 women on antenatal ultrasonographic and postnatal examinations. Each of 24 women with pregnancies complicated with VCI was matched at the onset of labor with 10 women who had a normal pregnancy, and FHR patterns were analyzed for both cases and controls. RESULTS Compared with controls, cases of variable decelerations with no accelerations (VDNA) during the first and second stages of labor were more frequent in women with VCI (first stage: 25% vs. 5.1%, second stage: 65.0% vs. 21.7%, P < 0.001). The adjusted odds ratio associated with VDNA occurrence in women with VCI was 3.83 (95% confidence interval [CI]: 1.51-9.72, P = 0.005). The mean odds ratio associated with length of aberrant vessels in women with VCI plus VDNA was 1.38 (95% CI: 1.04-1.83, P = 0.026). CONCLUSION Pregnancies complicated with VCI are associated with a higher rate of VDNA.

Abstract
Infants with congenital long QT syndrome (LQTS) and 2:1 atrioventricular block (AVB) have been recognized as a clinical subset of children with LQTS. However, the genotype of this disorder is not well-known. We report an infant with LQTS and 2:1 AVB with a mutation of the SCN5A gene (LQT3). In some patients with LQTS and 2:1 AVB, the disorder may be due to mutation of the SCN5A gene (LQT3).

Abstract
PURPOSE To understand the pathophysiology of central serous chorioretinopathy or bullous retinal detachment in patients under systemic corticosteroid treatment. Little is understood about the mechanism of the development of serous retinal detachment. METHODS Three patients who had developed central serous chorioretinopathy or bullous retinal detachment during systemic corticosteroid administration were examined by fluorescein angiography and indocyanine green angiography. RESULTS Indocyanine green angiography revealed dilated choroidal veins, delayed choroidal filling, intrachoroidal hyperfluorescence, and patchy hypofluorescence at or near the sites of dye leakage examined by fluorescein angiography. CONCLUSIONS The primary change caused by central serous chorioretinopathy is thought to occur in the choroid, followed by the breakdown of the outer blood-retinal barrier in the pigment epithelium, resulting in the development of serous retinal detachment.

Abstract
The progression of cardiomyopathy to congestive heart failure is often associated with the expression of fetal cardiac-specific genes. In mice, the basic helix-loop-helix transcription factors, dHAND and eHAND, are expressed in a cardiac chamber-specific fashion and are essential for fetal cardiac development, but are down-regulated in the adult. Their expression in specific chambers of healthy and diseased human hearts has not been studied previously. Human dHAND and eHAND were mapped to human chromosomes 4q33 and 5q33, respectively, by fluorescent in situ hybridization. RNA from the four chambers of healthy human adult hearts, and from hearts of patients with several forms of cardiomyopathy, was obtained and assayed for dHAND and eHAND expression. Unlike in mice, dHAND expression was observed in all four chambers of the healthy human adult heart, but was diminished in the right atrium. In contrast, eHAND was expressed in the right and left ventricles, but was downregulated in both atrial chambers. We examined tissue from 15 human cardiomyopathic hearts obtained during cardiac transplantation or by endomyocardial biopsy for alterations in HAND gene expression. dHAND expression was unchanged in all forms of cardiomyopathy tested. However, cardiac expression of eHAND was severely down-regulated in six of six patients with ischemic cardiomyopathy and six of six patients with dilated cardiomyopathy. This study demonstrates that human dHAND and eHAND have unique spatial patterns of expression within human cardiac chambers. Downregulation of eHAND in ischemic and dilated cardiomyopathy suggests a correlation between eHAND dysregulation and the evolution of a subset of cardiomyopathies.

Abstract
Although very low density lipoprotein (VLDL) receptor expression by macrophages has been shown in the vascular wall, it is not clear whether or not circulating monocytes express the VLDL receptor. We investigated the expression of VLDL receptor mRNA in human peripheral blood monocytes and monocyte-derived macrophages by reverse transcriptase polymerase chain reaction (RT-PCR) and nucleotide sequencing after subcloning of PCR product. VLDL receptor mRNA was detected both in peripheral blood monocytes and monocyte-derived macrophages. Expression of VLDL receptor mRNA was upregulated by hypoxia in monocytes, whereas treatment with oxidized LDL, interleukin-1beta or monocyte chemoattractant protein-1 did not affect the levels of VLDL receptor mRNA in monocytes and macrophages. The present study shows a novel response of VLDL receptor mRNA to hypoxia, suggesting a role for VLDL receptor in the metabolism of lipoproteins in the vascular wall and the development of atherosclerosis.

Abstract
We investigated menstrual cycle-dependent changes in the expression of PTHrP and PTH/PTHrP receptor in the human endometrium by immunohistochemistry, and competitive reverse transcription and polymerase chain reaction (RT-PCR). Human endometrial tissues were obtained from patients who underwent gynecological surgery due to cervical cancer (carcinoma in situ) or ovarian cancer. The mean age of the 20 patients was 36.5 (range 31-44) years. For analysis of mRNA expression, specimens from proliferative (mid, n=5; late, n=5) and secretory (early, n=4; mid, n=4) phases were used. Immunohistochemical expression of PTHrP and PTH/PTHrP receptor was observed in the cytoplasm of both epithelial and stromal cells. Stronger staining of PTHrP was found in glandular epithelial cells than in stromal cells. The staining during the proliferative phase was stronger than that in the secretory phase and the difference was particularly remarkable when comparing samples from the same patient. PTH/PTHrP receptor was also present in both epithelial and stromal cells of the endometrium. However, no difference was observed in receptor expression between the proliferative and secretory phases. Competitive RT-PCR revealed that the expression of PTHrP mRNA was higher during the proliferative phase than in the secretory phase, although no difference was observed in PTH/PTHrP receptor mRNA expression. The data suggest that endometrial proliferation may be mediated by a local PTHrP autocrine and/or paracrine mechanism.

Abstract
OBJECTIVES The current study evaluated the hypoxic induction of adrenomedullin gene expression and secretion, and its mechanism in cultured human umbilical vein endothelial cells (HUVEC). METHODS HUVEC were exposed to hypoxia or normoxia as controls for 1 to 24 h. Using Northern blot analysis and a radioimmunoassay, we evaluated adrenomedullin expression in HUVEC. The transcriptional component of adrenomedullin gene regulation was assessed by nuclear run-off experiments, and adrenomedullin mRNA half-life was measured by actinomycin D experiments. RESULTS We found that hypoxic conditions (1-3% oxygen) significantly increased adrenomedullin mRNA and protein in HUVEC. This increase was inversely proportional to oxygen tension and was reversible upon re-exposure to a 21% oxygen environment Nuclear run-off experiments revealed the enhanced transcriptional rate of adrenomedullin gene. Next, actinomycin D experiments revealed the enhanced adrenomedullin mRNA stability. CONCLUSIONS These results indicate that hypoxia increases adrenomedullin gene expression and secretion in HUVEC by transcriptional and post-transcriptional mechanisms. Hypoxic induction of adrenomedullin may play a pathophysiological role in the vascular systems.

Abstract
The Polycomb group of (Pc-G) genes and trithorax group of genes are known to play a crucial role in the maintenance of the transcriptional repression state of Hox genes, probably through modification of the chromatin configuration. The rae28/mph1 gene is a mammalian homologue of the Drosophila polyhomeotic gene, which belongs to the Pc-G genes. As reported previously, we established mice deficient in the rae28/mph1 gene and showed that these homozygous animals displayed the developmental defects compatible with a human congenital disorder, CATCH22 syndrome. In this study we analyzed the structural organization of the human counterpart of the rae28/mph1 gene (RAE28/HPH1) and its processed pseudogene (psiPH), which are located on, respectively, human chromosome 12p13 and 12q13. The HPH1 gene consists of 15 exons spanning approximately 26 kb and its structural organization is well conserved between mouse and human. These genetic information of the RAE28/HPH1 gene may provide an important clue for further examination of its involvement in human congenital disorders related to CATCH22 syndrome.
