Reference centiles for left ventricular longitudinal global and regional systolic strain by automated functional imaging in healthy Egyptian children.

Background: Two-dimensional speckle tracking echocardiography-derived left ventricular longitudinal systolic strain is an important myocardial deformation parameter for assessing the systolic function of the left ventricle. Strain values differ according to the vendor machine and software. This study aimed to provide normal reference values for global and regional left ventricular longitudinal systolic strain in Egyptian children using automated functional imaging software integrated into the General Electric healthcare machine and to study the correlation between the global longitudinal left ventricular systolic strain and age, body size, vital data, and some echocardiographic parameters.

COVID-19-Related Multisystem Inflammatory Syndrome in Children Presenting With New-Onset Type 1 Diabetes in Severe Ketoacidosis: A Case Series.

Objective: To report and describe cases of children presenting with coronavirus disease 2019 (COVID-19)-related multisystem inflammatory syndrome in children (MIS-C) with new-onset type 1 diabetes mellitus (T1DM) in severe diabetic ketoacidosis (DKA).

Research Design And Methods: This prospective observational study was conducted to characterize children with COVID-19-related MIS-C and new-onset T1DM who were in DKA. MIS-C was diagnosed if Centers for Disease Control and Prevention and World Health Organization criteria were fulfilled.

Detection of Early Myocardial Injury in Children with Ventricular Septal Defect Using Cardiac Troponin I and Two-Dimensional Speckle Tracking Echocardiography.

Children with ventricular septal defects (VSDs) are subjected to hemodynamic overload which causes myocardial injury and subsequent heart failure. Early stages of myocardial damage cannot be detected by conventional echocardiography. Two-dimensional speckle tracking echocardiography (2D-STE) and cardiac troponin I (cTnI) have been recently introduced as more accurate tools for early assessment of cardiovascular diseases.

Galectin-3 in Children with Chronic Heart Failure with Normal and Reduced Ejection Fraction: Relationship to Disease Severity.

Heart failure (HF) progression has not been studied in pediatric patients as well as HF in patients with a normal ejection fraction (HFNEF). We aimed to evaluate galactin-3 in children with HFNEF and reduced ejection fraction (HFREF) and its correlation to disease severity and progression. This cross-sectional study involved 45 chronic HF patients taking G1a (23 HFNEF children) and G1b (22 HFREF children) compared to 45 age- and sex-matched controls (G2) subjected to history taking, Ross functional HF classification, conventional and tissue Doppler echocardiographic systolic and diastolic function assessment (FS%, E/A, S , E /A , E/E ) and laboratory investigations [glomerular filtration rate, serum galactin-3 level (ELISA)].

N-Terminal proBNP Levels and Tissue Doppler Echocardiography in Acute Rheumatic Carditis.

Background. Rheumatic heart disease (RHD) is a leading cause of heart failure in children and young adults worldwide. B-type natriuretic peptide (BNP) is a useful marker of critical pediatric heart disease, and its N-terminal peptide, NT-proBNP, is elevated in congenital and acquired heart disease in children.

Can serum tenascin-C be used as a marker of inflammation in patients with dilated cardiomyopathy?

Background. Tenascin-C (TN-C) is an extracellular matrix glycoprotein that appears at sites of inflammation in cardiac pathologies. Aim of the Work.

Atrial natriuretic peptide as a marker of heart failure in children with left ventricular volume overload.

Aim: To evaluate the role of atrial natriuretic peptide (ANP) in differentiating the aetiology of heart failure in children with left ventricular (LV) volume overload.

Methods: The study was conducted on 48 patients with LV volume overload (G one: rheumatic heart disease in failure; G2: compensated rheumatic heart disease; G3: congenital left to right shunt; and G4: dilated cardiomyopathy). Twelve healthy children served as a control group.

Antistreptolysin O titer in health and disease: levels and significance.

Over diagnosis of acute rheumatic fever (ARF) based on a raised antistreptolysin O titer (ASOT) is not uncommon in endemic areas. In this study, 660 children (aged 9.2 ±1.
