Parental awareness and dental health behavior of children with congenital heart disease, with diabetes mellitus, or undergoing anti-cancer treatment, compared to healthy children.

Introduction: Children with chronic diseases tend to experience a considerably higher burden of oral disease compared to their healthy peers. Low awareness of the impact of systemic diseases on oral health, lack of motivation, and discomfort may render the maintenance of good oral hygiene challenging. We conducted a study of four groups of parents: of children with congenital heart disease (CHD), with diabetes mellitus type 1 (DM), and undergoing anti-cancer treatment (ACT); and a control group of healthy children (C).

Immune-Mediated Fetal Complete Atrioventricular Block: Can Dexamethasone Therapy Revert the Process?

Fetal complete atrioventricular block (CAVB) is usually autoimmune mediated. The risk of developing CAVB is 2% to 3% in anti-Ro/SS-A seropositive pregnancies and it increases 10 times after previous CAVB in siblings. Despite being a rare complication, CAVB carries a 20% mortality rate and substantial morbidity, as about 65% of newborns will eventually need life-long pacing.

Conotruncal malformations and absent thymus due to a deleterious NKX2-6 mutation.

Background: Truncus arteriosus (TA) accounts for ~1% of congenital heart defects. The aetiology of isolated TA is largely unknown but when occurring as part of a syndrome, it is mostly associated with chromosome 22q11 deletion. Vice versa, the most common congenital heart defects associated with chromosome 22q11 deletion are conotruncal malformations.

Prevalence of persistent superior vena cava and association with congenital heart anomalies.

A contralateral persistent superior vena cava (PSVC) can occur in a normal child or in association with congenital heart defects (CHDs). Its prevalence has been demonstrated in relatively small cohorts. We aim to assess the frequency of a PSVC in a large cohort of children with and without CHDs.

Intracardiac echogenic foci have no hemodynamic significance in the fetus.

Intracardiac echogenic foci (ECFs), probably representing microcalcifications of the papillary muscles, are a common finding in fetal ultrasonic screening examinations. Their significance is unclear, and their value as markers for chromosomal anomalies is debatable. It also is unknown whether ECFs predict abnormal cardiac performance.

Early diagnosis and treatment of atrioventricular block in the fetus exposed to maternal anti-SSA/Ro-SSB/La antibodies: a prospective, observational, fetal kinetocardiogram-based study.

Background: A fetus exposed to maternal anti-SSA/Ro or anti-SSB/La antibodies (or both) may develop complete atrioventricular block (AVB), which results in high prenatal and postnatal morbidity and mortality. Until recently, only high-grade AVB could be diagnosed in utero. The tissue velocity-based fetal kinetocardiogram (FKCG) enables accurate measurement of AV conduction time and diagnosis of low-grade AVB.

Analysis of segmental and global function of the fetal heart using novel automatic functional imaging.

Background: Functional assessment of the fetal heart has always been a challenge. Automatic functional imaging (AFI), a novel non-Doppler methodology based on 2-dimensional acoustic markers tracking, measures myocardial deformation regardless of angle of interrogation. Thus, we studied the validity of AFI in segmental and global assessment of myocardial function in the fetus.

Assessment of fetal myocardial performance using myocardial deformation analysis.

Conventional techniques for the assessment of cardiac function on the basis of M-mode or 2-dimensional modalities are technically difficult, load dependent, and provide information on global ventricular function only. Newer techniques, which analyze myocardial performance, such as tissue velocity, strain, and especially the less load dependent strain rate, may provide more appropriate information. Myocardial systolic and diastolic motion and performance were calculated using tissue velocity, strain, and strain rate imaging on a large cohort of normal fetuses.

Comparison of N-terminal pro-B-type natriuretic peptide levels in critically ill children with sepsis versus acute left ventricular dysfunction.

Objective: N-terminal pro-B-type natriuretic peptide has been shown to be a marker for cardiac dysfunction. The peptide level is also elevated in patients with sepsis. The purpose of this study was to assess whether N-terminal pro-B-type natriuretic peptide levels can differentiate pediatric patients with sepsis from patients with acute left ventricular dysfunction.

Tetralogy of Fallot with pulmonic atresia with cyclic occlusion of an associated aortic sinus of Valsalva-pulmonary artery window.

A first case of an unusual aortopulmonary window with tetralogy of Fallot associated with pulmonary atresia is presented. The aortopulmonary window was at the aortic sinus of Valsalva. The left aortic leaflet prevented pulmonary hypertension by occluding the window in systole.

Allicin-induced decrease in formation of fatty streaks (atherosclerosis) in mice fed a cholesterol-rich diet.

Background: Garlic (Allium sativum) has been considered to exhibit therapeutic features for many years. The effects of garlic on levels of serum lipids and on atherosclerosis have been investigated extensively. We have previously demonstrated that allicin, an active component of garlic, exerts a beneficial effect on lipid profile in hyperlipidemic rabbits.
