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.

AFib is caused by abnormal electrical impulses in the atria, which are the upper chambers of the heart. The result is a rapid and irregular pumping of blood through the atria. These chambers fibrillate, or quiver, rapidly.

Immunization Techniques

An intra-aortic balloon pump (IABP) is a mechanical device that helps the heart pump blood. This device is inserted into the aorta, the body's largest artery. It is a long, thin tube called a catheter with a balloon on the end of it. If you are hospitalized, your doctor may insert an IABP. Your doctor will numb an area of your leg and thread the IABP through the femoral artery in your leg into your aorta. He or she then positions the IABP at the center of your aorta, below your heart. The doctor will use an X-ray machine during this procedure to help accurately position the IABP. Why is it used? An IABP might be used to stabilize a person who is in the hospital for acute mitral valve regurgitation or severe heart failure. An IABP is only used for a short period of time (hours to days). A long-term treatment will likely be needed, such as valve surgery or the insertion of a left ventricular assist device (LVAD).

Giant cell arteritis is an inflammation of the lining of arteries. Most often, it affects the arteries in your head, especially those in your temples. For this reason, giant cell arteritis is sometimes called temporal arteritis. Giant cell arteritis frequently causes headaches, scalp tenderness, jaw pain and vision problems. If left untreated, it can lead to stroke or blindness. Prompt treatment with corticosteroid medications usually relieves symptoms of giant cell arteritis and may prevent loss of vision. You'll likely begin to feel better within days of starting treatment. But even with treatment, relapses are common. You'll need to visit your doctor regularly for checkups and treatment of any side effects from taking corticosteroids.

Cervical Stenosis Cervical Spinal Stenosis Video Spinal stenosis pain in the neck is called cervical spinal stenosis. This condition means that there is potential compression of the spinal cord. Unfortunately, the spinal cord compression can lead to serious problems such as extreme weakness, or even paralysis. With cervical stenosis, anyone who develops signs of spinal cord compression (myelopathy) may need more invasive treatment, such as surgery.

WARNING SIGNS OF BREAST CANCER Due to the use of regular mammography screening, most breast cancers in the U.S. are found at an early stage, before warning signs appear. However, not all breast cancers are found through mammography. The warning signs of breast cancer are not the same for all women. The most common signs are a change in the look or feel of the breast, a change in the look or feel of the nipple and nipple discharge. If you have any of the warning signs described below, see a health care provider [21-23]. If you do not have a provider, one of the best ways to find a good one is to get a referral from a trusted family member or friend. If that’s not an option, call your health department, a clinic or a nearby hospital.

Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is therapy using ionizing radiation, generally as part of cancer treatment to control or kill malignant cells. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body.

A dream is a succession of images, ideas, emotions, and sensations that usually occurs involuntarily in the mind during certain stages of sleep.[1] The content and purpose of dreams are not definitively understood, though they have been a topic of scientific speculation, as well as a subject of philosophical and religious interest, throughout recorded history. The scientific study of dreams is called oneirology

The goal of surgical clipping is to isolate an aneurysm from the normal circulation without blocking off any small perforating arteries nearby. Under general anesthesia, an opening is made in the skull, called a craniotomy. The brain is gently retracted to locate the aneurysm. A small clip is placed across the base, or neck, of the aneurysm to block the normal blood flow from entering. The clip works like a tiny coil-spring clothespin, in which the blades of the clip remain tightly closed until pressure is applied to open the blades. Clips are made of titanium and remain on the artery permanently.

HYSTERECTOMY RECOVERY: ALL PROCEDURES ARE NOT CREATED EQUAL Too often, women are only given the option of an open hysterectomy for conditions like large fibroids or an enlarged uterus. Surgical techniques have evolved in the last decade, but across the United States, the number of women still having open hysterectomy procedures is unnecessarily staggering. Robotic procedures are becoming more common as hospitals invest nearly $2 million in the machine. While the robot does allow surgeons who are not necessarily trained in laparoscopic procedures to perform a more minimally invasive surgery, tools cannot replace skill. There is no added benefit to the patient and the surgery can cost on average up to $2,000 more than other laparoscopic options, and in some cases much higher.

This video, Rheumatoid arthritis is a chronic inflammatory disorder that can affect more than just your joints. In some people, the condition also can damage a wide variety of body systems, including the skin, eyes, lungs, heart and blood vessels. An autoimmune disorder, rheumatoid arthritis occurs when your immune system mistakenly attacks your own body's tissues. Unlike the wear-and-tear damage of osteoarthritis, rheumatoid arthritis affects the lining of your joints, causing a painful swelling that can eventually result in bone erosion and joint deformity. The inflammation associated with rheumatoid arthritis is what can damage other parts of the body as well. While new types of medications have improved treatment options dramatically, severe rheumatoid arthritis can still cause physical disabilities.

Cellulitis (sel-u-LIE-tis) is a common, potentially serious bacterial skin infection. Cellulitis appears as a swollen, red area of skin that feels hot and tender. It can spread rapidly to other parts of the body. Cellulitis isn't usually spread from person to person. Skin on lower legs is most commonly affected, though cellulitis can occur anywhere on your body or face. Cellulitis might affect only your skin's surface. Or it might also affect tissues underlying your skin and can spread to your lymph nodes and bloodstream. Left untreated, the spreading infection can rapidly turn life-threatening. It's important to seek immediate medical attention if cellulitis symptoms occur.

Through the hormones it produces, the thyroid gland influences almost all of the metabolic processes in your body. Thyroid disorders can range from a small, harmless goiter (enlarged gland) that needs no treatment to life-threatening cancer. The most common thyroid problems involve abnormal production of thyroid hormones. Too much thyroid hormone results in a condition known as hyperthyroidism. Insufficient hormone production leads to hypothyroidism. Although the effects can be unpleasant or uncomfortable, most thyroid problems can be managed well if properly diagnosed and treated.

Thrombotic thrombocytopenic purpura (TTP) is a rare blood disorder characterized by clotting in small blood vessels of the body (thromboses), resulting in a low platelet count. In its full-blown form, the disease consists of the pentad of microangiopathic hemolytic anemia, thrombocytopenic purpura, neurologic abnormalities, fever, and renal disease
