Heart Sounds
Heart Sounds samer kareem 5,492 Views • 2 years ago

Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation, an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding the condition of the heart. In healthy adults, there are two normal heart sounds often described as a lub and a dub (or dup), that occur in sequence with each heartbeat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the atrioventricular valves and semilunar valves, respectively. In addition to these normal sounds, a variety of other sounds may be present including heart murmurs, adventitious sounds, and gallop rhythms S3 and S4. Heart murmurs are generated by turbulent flow of blood, which may occur inside or outside the heart. Murmurs may be physiological (benign) or pathological (abnormal). Abnormal murmurs can be caused by stenosis restricting the opening of a heart valve, resulting in turbulence as blood flows through it. Abnormal murmurs may also occur with valvular insufficiency (regurgitation), which allows backflow of blood when the incompetent valve closes with only partial effectiveness. Different murmurs are audible in different parts of the cardiac cycle, depending on the cause of the murmur.

The Epley maneuver is sometimes called the particle repositioning maneuver or the canalith repositioning maneuver. These names are used because the maneuver involves a series of movements that help to reposition crystals in a person's ear that may cause feelings of dizziness. Repositioning the crystals helps to relieve the person's dizziness and nausea.

Aortic Aneurysm and Aortic Dissection
Aortic Aneurysm and Aortic Dissection samer kareem 5,475 Views • 2 years ago

An aortic dissection is a serious condition in which the inner layer of the aorta, the large blood vessel branching off the heart, tears. Blood surges through the tear, causing the inner and middle layers of the aorta to separate (dissect). If the blood-filled channel ruptures through the outside aortic wall, aortic dissection is often fatal. Aortic dissection is relatively uncommon. The condition most frequently occurs in men in their 60s and 70s. Symptoms of aortic dissection may mimic those of other diseases, often leading to delays in diagnosis. However, when an aortic dissection is detected early and treated promptly, the chance of survival greatly improves.

Stem Cell Injection Alternative to Surgery
Stem Cell Injection Alternative to Surgery samer kareem 5,470 Views • 2 years ago

Adult stem cells are cells from your own body that can renew themselves and turn into other cells (differentiate). They live inside all of us in various tissues, poised to leap into action to repair damage as it occurs. As we age or have big injuries, we may not be able to recruit enough of these cells to the site to fully repair the area. Regenexx Stem Cell Procedures help overcome this problem by extracting stem cells from an area of high volume, then concentrating the cells and reinjecting them into the damaged area to help the body heal naturally.

False Pregnancy in Women
False Pregnancy in Women samer kareem 5,461 Views • 2 years ago

The physical signs of pregnancy are easy to recognize -- nausea, fatigue, that swollen belly and (often) a healthy glow. But what if you had these telltale pregnancy symptoms -- and weren't actually pregnant? As crazy as it sounds, it does happen. False pregnancy, or pseudocyesis, is a condition in which a woman believes that she's pregnant, yet conception hasn't taken place and no baby is forming inside. Common, and often lasting, pregnancy symptoms help to reinforce this idea, which can lead a woman to be absolutely certain she's expecting, for months or even years!

Insulin Resistance
Insulin Resistance samer kareem 5,461 Views • 2 years ago

Insulin is a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia). The cells in your body need sugar for energy. However, sugar cannot go into most of your cells directly. After you eat food and your blood sugar level rises, cells in your pancreas (known as beta cells) are signaled to release insulin into your bloodstream. Insulin then attaches to and signals cells to absorb sugar from the bloodstream. Insulin is often described as a “key,” which unlocks the cell to allow sugar to enter the cell and be used for energy.

Progeria
Progeria samer kareem 5,446 Views • 2 years ago

Progeria (pro-JEER-e-uh), also known as Hutchinson-Gilford syndrome, is an extremely rare, progressive genetic disorder that causes children to age rapidly, beginning in their first two years of life. Children with progeria generally appear normal at birth. During the first year, signs and symptoms, such as slow growth and hair loss, begin to appear. Heart problems or strokes are the eventual cause of death in most children with progeria. The average life expectancy for a child with progeria is about 13 years, but some with the disease die younger and some live 20 years or longer. There's no cure for progeria, but ongoing research shows some promise for treatment.
