Pathological Demand Avoidance of PDA is becoming more widely recognized as a distinct profile of autism. British psychologist Demand avoidance in the PDA profile looks different from what others on the autism spectrum experience because of its extreme nature and obsessive quality. This extreme avoidance extends to the most basic demands of everyday living, not just the avoidance of unpleasant, difficult, specific anxiety-provoking or unappealing tasks. Someone with a PDA profile will also have tremendous difficulty complying with their own self-imposed expectations and with doing things that they really want to do. (PDA Society, UK) PDA is seen in both genders equally. There are no prevalence rates available at this time. It is not caused by a how a person was raised or their social circumstances; it’s not the fault of the parents or the individual with the condition. PDA is not recognized in the DSM-V so not all professionals agree with this profile. We have not heard much about PDA in North America yet, although the term is starting to become more known. The interest in PDA as a distinct profile is growing and more Features of Pathological Demand Avoidance ( from the PDA Society, UK) 1)Resisting and avoiding the ordinary demands of life This might include getting up, joining a family activity or getting dressed to name but a few. This may be the case even when the person wants to do what has been suggested, such as watching a film that they have been looking forward to. ...

Patent ductus arteriosus, or PDA, is a heart defect that can develop soon after birth. It affects the way blood flows through a baby’s lungs. Mild PDA might not need treatment, but some children with the defect may require catheterization or surgery. Pediatric cardiologist What is patent ductus arteriosus? PDA occurs when the opening between the aorta (the artery that carries oxygen-rich blood to the body) and the pulmonary artery (the artery that carries oxygen-poor blood to the lungs) does not close as it should. How does patent ductus arteriosus affect blood flow? PDA causes too much blood to flow into babies’ lungs. While a baby develops in the womb, an opening between the aorta and pulmonary artery (the ductus arteriosus) allows blood to bypass the baby’s lungs and go straight to the body. Blood does not need to go to the lungs first, because the mother supplies the baby with oxygenated blood through the placenta. The ductus arteriosus should close on its own within a few days after birth. When the opening does not close, this connection between arteries is considered a patent, or open, ductus arteriosus. Small connections may not cause problems, but larger connections can cause a range of symptoms and require closure. Patent Ductus Arteriosus Causes Experts aren’t sure exactly what causes PDA. It is much more common in premature infants (babies born more than three weeks before the projected due date). Studies suggest PDA affects about 65% of infants born before the ...

Patent ductus arteriosus Patent ductus arteriosus is a persistent opening between the two main blood vessels leaving the heart. Those vessels are the aorta and the pulmonary artery. The condition is present at birth. Patent ductus arteriosus (PDA) is a persistent opening between the two major blood vessels leading from the heart. The heart problem is present from birth. That means it is a congenital heart defect. An opening called the ductus arteriosus is part of a baby's blood flow system in the womb. It usually closes shortly after birth. If it remains open, it's called a patent ductus arteriosus. A small patent ductus arteriosus often doesn't cause problems and might never need treatment. However, a large, untreated patent ductus arteriosus can let oxygen-poor blood move the wrong way. This can weaken the heart muscle, causing heart failure and other complications. Treatment options for a patent ductus arteriosus include regular health checkups, medicines, and a procedure or surgery to close the opening. Symptoms Patent ductus arteriosus symptoms (PDA) depend on the size of the opening and the person's age. A small PDA might not cause symptoms. Some people don't notice symptoms until adulthood. A large PDA can cause symptoms of heart failure soon after birth. A large PDA found during infancy or childhood might cause: • Poor eating, which leads to poor growth. • Sweating with crying or eating. • Persistent fast breathing or breathlessness. • Easy tiring. • Rapid heart ra...

Patent ductus arteriosus (PDA) is a heart condition that affects some babies (more often, those born prematurely). PDA causes problems with blood flow between the heart and lungs. PDA sometimes resolves on its own. When it doesn’t, healthcare providers treat PDA and restore normal circulation with medication, catheterization and surgery. Overview Patent ductus arteriosus (PDA) causes problems with blood flow between the heart and lungs. What is patent ductus arteriosus (PDA)? Patent ductus arteriosus (PDA) is a heart condition in babies. It happens when a blood vessel called the ductus arteriosus doesn’t close as it should after birth. What does the ductus arteriosus do? During What happens in babies with patent ductus arteriosus? When a baby has a PDA, the ductus arteriosus doesn’t close properly. A small opening is left. The opening allows extra blood from the aorta to enter the baby’s lung arteries. Depending on the size of this blood vessel, your baby’s Who does PDA affect? Babies How common is PDA? Patent ductus arteriosus is the most common heart condition in newborns. Healthcare providers diagnose the condition more often in premature babies. The risk increases the earlier the baby is born. PDA happens in about: • 10% of babies born between 30 and 37 weeks of pregnancy. • 80% of babies born between 25 and 28 weeks of pregnancy. • 90% of babies born earlier than 24 weeks of pregnancy.

Stenosis of RCA and PDA RCA: right coronary artery; PDA: posterior descending coronary artery.PLV: posterior left ventricular branch, also known as PLB. Right coronary angiogram showing stenosis of RCA and PDA. RCA shows two lesions, one in the proximal region and another distally just before the crux where PDA and PLV branches originate (pre-crux stenosis of RCA). RCA is seen to be a bittortuous. Difficulty in passing balloons for angioplasty (PTCA balloons) and coronary stents should be anticipated in very tortuous vessels. In such cases the guide catheter tends to back out into the aorta when we try to push the device (balloon or stent) deeper into the vessel. We may need to straighten out the tortuosity using additional stiffer guide wires (buddy wire) or use other techniques like anchor balloon or deep throat the catheter in order to improve guide support during angioplasty / stenting. PDA shows three tandem stenoses from proximal to distal region. PDA appears to be a smaller caliber vessel than PLV. This could also be because the vessel is underfilled due to the tandem stenoses. Very often the vessel size increases remarkably after opening up the lesions by balloon angioplasty / stenting. This is a right dominant system meaning that the right coronary system crosses the crux, the junction of atrioventricular and interventricular grooves posteriorly and supplies the posterolateral region of the left ventricle. It may be noted that even in right dominant systems, the m...
