Lung Prematurity
Lung Prematurity samer kareem 6,035 Views • 2 years ago

Pulmonary surfactant is a mixture of lipids and proteins that is produced by alveolar type II epithelial cells (AEC2) and secreted into the airspaces. Phospholipids are the major component of surfactant by weight, and are essential for lowering surface tension at the air-liquid interface, which prevents alveolar collapse at end-expiration. Four proteins highly expressed in the lung and found in surfactant are designated surfactant proteins (SP) A, B, C, and D. Additional proteins including ABCA3 and NKX2.1 are also important for the production of functional surfactant. The surfactant proteins are developmentally regulated, such that their expression increases in later gestation

Tendon Repair
Tendon Repair samer kareem 59,757 Views • 2 years ago

Tendon repair can be performed using: Local anesthesia (the immediate area of the surgery is pain-free) Regional anesthesia (the local and surrounding areas are pain-free) General anesthesia (the patient is asleep and pain-free) The surgeon makes a cut on the skin over the injured tendon. The damaged or torn ends of the tendon are sewn together. If the tendon has been severely injured, a tendon graft may be needed. In this case, a piece of tendon from the foot, toe, or another part of the body is often used. If needed, tendons are reattached to the surrounding tissue. The surgeon examines the area to see if there are any injuries to nerves and blood vessels. When the repair is complete, the wound is closed. If the tendon damage is too severe, the repair and reconstruction may have to be done at different times. The surgeon will perform one surgery to repair part of the injury, and then allow the hand to heal for a few weeks. Another surgery will be done later to complete the reconstruction and repair the tendon.

Tonsilitis
Tonsilitis samer kareem 2,245 Views • 2 years ago

Tonsillitis is inflammation of the tonsils, two oval-shaped pads of tissue at the back of the throat — one tonsil on each side. Signs and symptoms of tonsillitis include swollen tonsils, sore throat, difficulty swallowing and tender lymph nodes on the sides of the neck. Most cases of tonsillitis are caused by infection with a common virus, but bacterial infections also may cause tonsillitis. Because appropriate treatment for tonsillitis depends on the cause, it's important to get a prompt and accurate diagnosis. Surgery to remove tonsils, once a common procedure to treat tonsillitis, is usually performed only when bacterial tonsillitis occurs frequently, doesn't respond to other treatments or causes serious complications.

Cardiac disease in pregnancy
Cardiac disease in pregnancy samer kareem 1,622 Views • 2 years ago

An increased prevalence of cardiovascular disease (CVD) has been found in women of childbearing age,[1] with the presence of CVD in pregnant women posing a difficult clinical scenario in which the responsibility of the treating physician extends to the unborn fetus. Profound changes occur in the maternal circulation that have the potential to adversely affect maternal and fetal health, especially in the presence of underlying heart conditions. Up to 4% of pregnancies may have cardiovascular complications despite no known prior disease. The European Society of Cardiology has published guidelines on the management of cardiovascular disease during pregnancy.[

Graves' Disease
Graves' Disease samer kareem 2,847 Views • 2 years ago

Graves' disease is an immune system disorder that results in the overproduction of thyroid hormones (hyperthyroidism). Although a number of disorders may result in hyperthyroidism, Graves' disease is a common cause. Because thyroid hormones affect a number of different body systems, signs and symptoms associated with Graves' disease can be wide ranging and significantly influence your overall well-being. Although Graves' disease may affect anyone, it's more common among women and before the age of 40. The primary treatment goals are to inhibit the overproduction of thyroid hormones and lessen the severity of symptoms.

Amnesia
Amnesia samer kareem 5,634 Views • 2 years ago

Amnesia refers to the loss of memories, such as facts, information and experiences. Though having no sense of who you are is a common plot device in movies and television, real-life amnesia generally doesn't cause a loss of self-identity. Instead, people with amnesia — also called amnestic syndrome — are usually lucid and know who they are, but may have trouble learning new information and forming new memories. Amnesia can be caused by damage to areas of the brain that are vital for memory processing. Unlike a temporary episode of memory loss (transient global amnesia), amnesia can be permanent. There's no specific treatment for amnesia, but techniques for enhancing memory and psychological support can help people with amnesia and their families cope.

HIV Replication
HIV Replication samer kareem 6,739 Views • 2 years ago

HIV gradually destroys the immune system by attacking and killing a type of white blood cell called a CD4 cell. CD4 cells play a major role in protecting the body from infection. HIV uses the machinery of the CD4 cells to multiply (make copies of itself) and spread throughout the body. This process, which is carried out in seven steps or stages, is called the HIV life cycle. HIV medicines protect the immune system by blocking HIV at different stages of the HIV life cycle. Antiretroviral therapy or ART is the use of HIV medicines to treat HIV infection. People on ART take a combination of HIV medicines from at least two different HIV drug classes every day. Because each class of drugs is designed to target a specific step in the HIV life cycle, ART is very effective at preventing HIV from multiplying. ART also reduces the risk of HIV drug resistance. ART can’t cure HIV, but HIV medicines help people with HIV live longer, healthier lives. ART also reduces the risk of HIV transmission (the spread of HIV to others).

Unraveling the Mystery of Alzheimer's Disease
Unraveling the Mystery of Alzheimer's Disease samer kareem 21,386 Views • 2 years ago

Alzheimer's worsens over time. Alzheimer's is a progressive disease, where dementia symptoms gradually worsen over a number of years. In its early stages, memory loss is mild, but with late-stage Alzheimer's, individuals lose the ability to carry on a conversation and respond to their environment. Alzheimer's is the sixth leading cause of death in the United States. Those with Alzheimer's live an average of eight years after their symptoms become noticeable to others, but survival can range from four to 20 years, depending on age and other health conditions. Alzheimer's has no current cure, but treatments for symptoms are available and research continues. Although current Alzheimer's treatments cannot stop Alzheimer's from progressing, they can temporarily slow the worsening of dementia symptoms and improve quality of life for those with Alzheimer's and their caregivers. Today, there is a worldwide effort under way to find better ways to treat the disease, delay its onset, and prevent it from developing.

Parkinson's Disease Drugs
Parkinson's Disease Drugs samer kareem 1,876 Views • 2 years ago

There have been rapid and remarkable changes over the recent past in treating Parkinson's disease. The development of new drugs and an understanding of how best to use them and the older drugs have significantly improved the quality of life of people with the disease. There are two general approaches to the treatment of Parkinson's disease with medication. The first approach attempts to increase the levels of dopamine in the brain and the second approach attempts to improve the symptoms of Parkinson's disease by other means. Most patients with Parkinson's disease can initially be treated with drugs that adequately alleviate their symptoms. If or when medications are not sufficiently effective, new, highly effective and safe surgical treatments are also available.

Candidate for a Total Knee Replacement
Candidate for a Total Knee Replacement samer kareem 1,303 Views • 2 years ago

If your knee is severely damaged by arthritis or injury, it may be hard for you to perform simple activities, such as walking or climbing stairs. You may even begin to feel pain while you are sitting or lying down. If nonsurgical treatments like medications and using walking supports are no longer helpful, you may want to consider total knee replacement surgery. Joint replacement surgery is a safe and effective procedure to relieve pain, correct leg deformity, and help you resume normal activities. Knee replacement surgery was first performed in 1968. Since then, improvements in surgical materials and techniques have greatly increased its effectiveness. Total knee replacements are one of the most successful procedures in all of medicine. According to the Agency for Healthcare Research and Quality, more than 600,000 knee replacements are performed each year in the United States. Whether you have just begun exploring treatment options or have already decided to have total knee replacement surgery, this article will help you understand more about this valuable procedure.
