Justify teaching of Mathematics or Science in ECD?

It is very important to teach mathematics and science in ECD (Early Childhood Development). When children are this age, this is when you want to get them interested in learning about different things that will last a life time. Children understand the world around them through experiments and observations which are the guides of mathematics and science, hence important at ECD level to catch them young.

Endocardial cushion defect?

DefinitionEndocardial cushion defect (ECD) is an abnormal heart condition in which the walls separating all four chambers of the heart are poorly formed or absent. It is a congenital heart disease, which means it is present from birth.Alternative NamesAtrioventricular (AV) canal defect; Atrioventricular septal defect; AVSDCauses, incidence, and risk factorsEndocardial cushion defect occurs while a baby is still growing in the womb. The endocardial cushions are two areas of thickening that eventually develop into the wall (septum) that separates the four chambers of the heart. They also form the mitral and tricuspid valves, the valves that separate the atria (top collecting chambers) from the ventricles (bottom pumping chambers).The lack of separation between the two sides of the heart causes several problems:Increased blood pressure in the lungs. In persons with this condition, blood flows through the abnormal openings from the left to the right side of the heart, then to the lungs. The increased blood flow into the lungs leads to a rise in blood pressure in the lungs.Lung irritation and inflammation. Increased blood flow into the lungs causes irritation and swelling.Heart failure. Because the heart has to pump more blood to the lungs, it has to work much harder than normal. The heart may enlarge and weaken.Cyanosis. As the blood pressure increases in the lungs, blood flow starts to move from the right side of the heart to the left. The oxygen-poor blood mixes with the oxygen-rich blood, and blood with less oxygen than usual is pumped out to the body. This causes cyanosis, or bluish coloring of the skin.There are two types of ECD:Complete ECD: A complete ECD involves an atrial septal defect (ASD) and a ventricular septal defect (VSD). Persons with a complete ECD have only one large heart valve (common AV valve) instead of two distinct valves (mitral and tricuspid).Partial (or incomplete) ECD: Only an ASD is present. There are two distinct valves, but one of them (the mitral valve) is often abnormal with an opening ("cleft") in it, letting blood leak between the two left chambers of the heart.ECD is strongly associated with Down syndrome. Several gene changes are also connected to ECD. However, the exact cause of ECD is unknown.ECD may be associated with other congenital heart defects such as:Double outlet right ventricleSingle ventricleTransposition of the great vesselsTetralogy of FallotSymptomsSymptoms of ECD may include:Baby tires easilyBluish skin color (the lips may also be blue)Failure to gain weight and growFrequent pneumoniaLack of appetitePale skin (pallor)Rapid breathingRapid heartbeatSweatingSwollen legs or abdomen (rare in children)Trouble breathing, especially during feedingSigns and testsSigns of ECD may include:An abnormal electrocardiogram (ECG)An enlarged heartHeart murmurChildren with partial ECD, who have only a small VSD and normal valves, may not have signs or symptoms of the disorder during childhood.Tests to diagnose ECD include:Ultrasound of the heart (echocardiogram) to see blood flowAn electrocardiogram (ECG), which measures the electrical activity in the heartChest x-ray, which may show an enlarged heartMagnetic resonance imaging (MRI) of the heart, which provides a detailed image of the heart through the use of powerful magnetsCardiac catheterization (in some cases), a procedure in which a thin tube (catheter) is placed into the heart to see blood flow and take accurate measurements of blood pressure and oxygen levelsTreatmentSurgery is needed to close the holes between the heart chambers, and to separate the common valve into distinct tricuspid and mitral valves. The timing of the surgery depends on the child's condition and the severity of the ECD. It can usually be done when the baby is 3 - 6 months old. Correcting an ECD may require more than one surgery.Your doctor may prescribe medication before surgery if the ECD has made your baby very sick. The medicines will help the child gain weight and strength before surgery. Medications may include:Diuretics (water pills)Drugs that make the heart contract more forcefully (inotropic agents), such as digoxinSurgery for a complete ECD should be done as early in the baby's first year of life as possible, before irreversible lung damage occurs. Babies with Down syndrome tend to develop lung disease earlier, and therefore early surgery is very important for these babies.See also:Congenital heart defect corrective surgeryPediatric heart surgeryExpectations (prognosis)How well your baby does depends on the severity of the ECD, the child's overall health, and whether lung disease has already developed. Many children live normal, active lives after the ECD is corrected. ComplicationsComplications from ECD may include:Congestive heart failureDeathEisenmenger syndromeHigh blood pressure in the lungsIrreversible damage to the lungsCertain complications of ECD surgery may not appear until the child is an adult. These include heart rhythm problems and a leaky mitral valve.Children with congenital heart disease may need to take antibiotics before dental treatment. This helps prevent complications related to heart infections. Ask a cardiologist whether your child needs to take antibiotics.Calling your health care providerCall your health care provider if your child seems to tire easily, has trouble breathing, or has bluish skin or lips. You should also consult your health care provider if your baby is not growing or gaining weight. PreventionECD is associated with several genetic abnormalities. Couples with a family history of ECD may wish to seek genetic counseling before becoming pregnant.ReferencesPark MK. Pediatric Cardiology for Practitioners, 5th ed.
