Abstract
BACKGROUND Congenital heart disease occurs in approximately 1 in 100 cases. Although sibling occurrence is high (3-9%), the causative genes for this disease are still being elucidated. PLD1 (Phospholipase D1) is a recently discovered gene; however, few case reports have been published on it. In this report, we describe a case of triplicate fetal congenital heart disease that was diagnosed as a PDL1 mutation. Our objective is to explore the clinical manifestations of PLD1 mutations in this particular case. CASE PRESENTATION A 32-year-old Japanese woman (gravida, para 0) was introduced since fetus four chamber view was not clear and was diagnosed with ductus arteriosus-dependent left ventricular single ventricle and pulmonary atresia at 21 weeks and 1 day of gestation during her first pregnancy. Artificial abortion using Gemeprost was performed at 21 weeks and 5 days of gestation. The second pregnancy was diagnosed as pulmonary atresia with intact ventricular septum with cardiomegaly, a cardiothoracic area ratio of more than 35%, and a circulatory shunt at 13 weeks and 3 days of gestation. Subsequently, intrauterine fetal death was confirmed at 14 weeks and 3 days of gestation. Regarding the third pregnancy, fetal ultrasonography at 11 weeks and 5 days of gestation showed mild fetal hydrops and moderate tricuspid valve regurgitation. At 16 weeks and 5 days of gestation, the fetus was suspected to have a left ventricular-type single ventricle, trace right ventricle, pulmonary atresia with intact ventricular septum, or cardiomyopathy. Cardiac function gradually declined at 26 weeks of gestation, and intrauterine fetal death was confirmed at 27 weeks and 5 days of gestation. The fourth pregnancy resulted in a normal heart with good progression and no abnormal baby. We submitted the first and second fetuses' umbilical cord, third fetus' placenta, and the fourth fetus' blood to genetic testing using whole exome analysis with next generation sequencing. Genetic analysis identified hemizygous PLD1 mutations in the first, second, and third fetuses. The fourth fetus was heterozygous. In addition, the parents were heterozygous for PLD1. This case is based on three consecutive cases of homozygosity for the PLD1 gene in the sibling cases and the fetuses with recurrent right ventricular valve dysplasia. This will elucidate the cause of recurrent congenital heart disease and intrauterine fetal death and may serve as an indicator for screening the next fetus. To date, homozygous mutations in PLD1 that repeat three times in a row are not reported, only up to two times. The novelty of this report is that it was repeated three times, followed by a heterozygous live birth. CONCLUSIONS This report is consistent with previous reports that mutations in PLD1 cause right ventricular valve dysplasia. However, there have been few case reports of PLD1 mutations, and we hope that this report will contribute to elucidate the causes of congenital heart disease, especially right ventricular valve dysplasia, and that the accumulation of such information will provide more detailed information on PLD1 mutations in heart disease.

Abstract
Atherosclerosis can develop in adult patients with congenital heart disease (CHD) and should be given attention. Endothelial function is well known as a predictor of the development of atherosclerosis but has not been well investigated in patients with repaired CHD. This study aimed to clarify the endothelial function and its relationship with clinical backgrounds and parameters in adolescents with various types of repaired CHDs. Endothelial function was evaluated using peripheral arterial tonometry (PAT). The reactive hyperemia index (RHI) was evaluated and compared between adolescents with repaired CHD and those in the control group. The relationship between the clinical background and parameters was also investigated in patients with repaired CHD. Forty-eight patients with repaired CHD (age 14.0 ± 3.3 years) and 114 healthy volunteers were included in this study. Patients with repaired CHD comprised 16 with repaired non-cyanotic CHD, 14 with repaired tetralogy of Fallot, and 18 who underwent the Fontan procedure. RHI in the repaired CHD group was significantly lower than in the control group. There was no significant correlation between the RHI and blood biochemical markers, such as uric acid, creatine, and brain natriuretic peptide levels. The RHI was significantly higher in patients taking angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) than in those not taking them. Endothelial function was impaired in adolescents with repaired CHD compared to that in the control group. Microvascular endothelial dysfunction developed even in adolescents with simple non-cyanotic CHD.

Abstract
Background Brain abscesses are relatively rare, but they are a potentially life-threatening condition. Predictive factors for poor outcome are a young age and the presence of multiple abscesses. We report a case of a 15-month-old girl with cyanotic congenital heart disease who developed multiple brain abscesses caused by Streptococcus intermedius. The patient was treated with a combination of surgical aspiration and antimicrobial therapy without apparent neurological sequelae. To the best of our knowledge, this is the youngest such patient to have been reported in the literature. We explore the possible causes of her good outcome. Case presentation At the age of 15 months, the Japanese patient initially was presented to our hospital with transient eye deviation to the left and vomiting. In a blood examination, her white blood cell count (12,720 per mm3 with a left shift) and C-reactive protein level (1.23 mg/ml) were slightly elevated. Magnetic resonance imaging of the brain showed three mass lesions. These were 1.5-cm, 1.9-cm, and 1.2-cm rim-enhancing lesions with extensive surrounding edema. Brain abscesses were diagnosed, and vancomycin (50 mg every 12 hours) and meropenem (40 mg every 8 hours) were started empirically. However, because each brain abscess was enlarged at 8 days after admission, surgical aspiration was performed at 10 days after admission, and cultures of the aspirated pus grew S. intermedius. Penicillin G (0.7 million units every 4 hours) and ceftriaxone (280 mg every 12 hours), to which this isolate is susceptible, were then administered, and the brain abscesses reduced in size. After 1 month of ceftriaxone and 3 months of penicillin G treatment, all of the brain abscesses disappeared. Apparent neurological sequelae were not observed at 6 months after onset. Conclusions A good outcome can be obtained if multiple brain abscesses develop in infancy or early childhood in cases without unconsciousness at admission, meningitis, or sepsis. Appropriate antimicrobial therapy should be started immediately after diagnosis, with surgical aspiration performed to identify the causative pathogen and avoid intraventricular rupture of the brain abscesses.

Abstract
Endothelial dysfunction is the early predictive factor for the development of atherosclerosis and future cardiovascular diseases in adulthood. The prevalence of endothelial dysfunction in children and early adolescents is increasing worldwide. Peripheral arterial tonometry is a noninvasive technique for assessing peripheral microvascular function and is used as a validated marker of endothelial function. We assessed anthropometric parameters, blood pressure, arterial stiffness, and peripheral endothelial function in 157 Japanese early adolescents (75 boys and 82 girls). We measured peripheral endothelial function by using peripheral arterial tonometry to determine the reactive hyperemia index, and assessed the association of reactive hyperemia index with parameters of anthropometry and arterial stiffness. The mean reactive hyperemia index of all subjects was 1.85 ± 0.6, and there was no difference of reactive hyperemia index according to sex. Reactive hyperemia index was significantly associated with systolic and diastolic blood pressures, and had no correlation with anthropometric parameters and arterial stiffness markers. The reactive hyperemia index values among Japanese early adolescents were similar to those reported in previous studies on children and early adolescents. This noninvasive technique may be useful for the assessment of microvascular endothelial function among children and early adolescents.

Abstract
We report the case of a newborn baby with an unguarded mitral orifice associated with asplenia syndrome, double-outlet right ventricle, dysplastic tricuspid valve, and pulmonary stenosis. This case was accompanied by severe tricuspid regurgitation and severe right ventricular hypertrophy. The patient had a fatal clinical course due to severe hypoxia and congestive heart failure. Unguarded mitral orifice is a rare disease in which there has been no previous report of lethal clinical course during the neonatal period. Prior reports stated that unguarded mitral orifice was a new constellation of defects and that its etiology and embryology could be classified in the same category because of similar associated malformations of double-outlet right ventricle and pulmonary stenosis or atresia. However, the present case was diagnosed on autopsy as also having asplenia syndrome. Therefore, it is possible that the genetic etiology of unguarded mitral orifice in this case was different from cases of non-heterotaxy. <Learning objective: Unguarded mitral orifice is a rare disease that might be associated with asplenia syndrome and dysplastic tricuspid valve. If unguarded mitral orifice is associated with such defects, the clinical course can be fatal. Therefore, when this diagnosis is recognized, the physician should explain the possibility of neonatal death and plan the treatment of such a case to include grief therapy for the family.>.

Abstract
Recently, many cases of children presenting reversible splenial lesions during febrile illness (RESLEF) have been reported; however, their overall clinico-radiological features are unclear. To describe the clinico-radiological features, we retrospectively reviewed the etiology (pathogen), clinical course, laboratory data, magnetic resonance imaging and electroencephalography (EEG) findings, therapy, and prognosis of 23 episodes in 22 children (1 child recurred) who presented neurological symptoms, with RESLEF. The etiologies (pathogens) varied. Seizure occurred in 7 episodes, disturbance of consciousness (DC) in 13, and delirious behavior in 18. Serum sodium levels <136 mEq/L were observed in 18 episodes. Lesions outside the splenium were found in 4 cases. Slow waves were observed on EEG in 10 episodes. Methylprednisolone pulse therapy was given in 7 cases. No case resulted in neurological sequelae. Among 23 episodes, clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) was diagnosed in 6 episodes, whereas non-MERS was observed in 17 episodes. No difference was observed in almost all the clinico-radiological features' data between the 2 groups. The largest differences were observed in the rate of purposeless movement, DC, extension of the abnormal lesions outside the splenium, and marked slowing of background activity on EEG. RESLEF exhibit a spectrum of clinico-radiological features. These results suggest that non-MERS and MERS both are a part of a larger pathological condition, which we have termed as RESLEF spectrum syndrome. Given the view that such a syndrome exists, the clinical characteristics and position of non-MERS and MERS become clear.

Abstract
The radical modulation activity of hot water and alkaline extracts from leaf of Ceriops decandra, a mangrove plant, was investigated using ESR spectroscopy. IR and NMR analyses demonstrate that the leaf extracts have a lignin-like polyphenolic structure. All these extracts produced radical(s) under alkaline conditions. The radical intensity of sodium ascorbate was slightly reduced at lower concentrations of the extracts, but it was synergistically enhanced at higher concentrations. All the extracts effectively scavenged superoxide anion, produced by hypoxanthine-xanthine oxidase reaction. Pretreatment of mice with the extracts significantly protected them from the lethal infection by E. coli. Similar activity was found in lignins from pine seed shell of Pinus parviflora Sieb. et Zucc. These data further support the medicinal efficacy of plant extracts.
