Marfan Syndrome Diagnosis and Treatment
Marfan Syndrome Diagnosis and Treatment samer kareem 9,851 Views • 3 years ago

Marfan syndrome is a genetic disorder that affects the body’s connective tissue. Connective tissue holds all the body’s cells, organs and tissue together. It also plays an important role in helping the body grow and develop properly. marfan_general_2.jpg What is Marfan Syndrome?Connective tissue is made up of proteins. The protein that plays a role in Marfan syndrome is called fibrillin-1. Marfan syndrome is caused by a defect (or mutation) in the gene that tells the body how to make fibrillin-1. This mutation results in an increase in a protein called transforming growth factor beta, or TGF-β. The increase in TGF-β causes problems in connective tissues throughout the body, which in turn creates the features and medical problems associated with Marfan syndrome and some related disorders. Because connective tissue is found throughout the body, Marfan syndrome can affect many different parts of the body, as well. Features of the disorder are most often found in the heart, blood vessels, bones, joints, and eyes. Some Marfan features – for example, aortic enlargement (expansion of the main blood vessel that carries blood away from the heart to the rest of the body) – can be life-threatening. The lungs, skin and nervous system may also be affected. Marfan syndrome does not affect intelligence.

Narcolepsy
Narcolepsy samer kareem 10,819 Views • 3 years ago

Narcolepsy is a chronic sleep disorder characterized by overwhelming daytime drowsiness and sudden attacks of sleep. People with narcolepsy often find it difficult to stay awake for long periods of time, regardless of the circumstances. Narcolepsy can cause serious disruptions in your daily routine. Sometimes, narcolepsy can be accompanied by a sudden loss of muscle tone (cataplexy) that leads to weakness and loss of muscle control. Cataplexy is often triggered by a strong emotion, most commonly laughter. Narcolepsy is a chronic condition for which there's no cure. However, medications and lifestyle changes can help you manage the symptoms. Support from others — family, friends, employer, teachers — can help you cope with narcolepsy.

What is an Ileostomy?
What is an Ileostomy? samer kareem 3,213 Views • 3 years ago

An ileostomy is an opening in the belly (abdominal wall) that’s made during surgery. The end of the ileum (the lowest part of the small intestine) is brought through this opening to form a stoma, usually on the lower right side of the abdomen. A Wound Ostomy Continence nurse (WOCN or WOC nurse) or the surgeon will figure out the best location for your stoma. (A WOC nurse is a specially trained registered nurse who takes care of and teaches ostomy patients. This nurse may also be called an ostomy nurse.)

What is Thalassemia
What is Thalassemia samer kareem 1,744 Views • 3 years ago

Thalassemia is a genetic blood disorder. People with Thalassemia disease are not able to make enough hemoglobin, which causes severe anemia. Hemoglobin is found in red blood cells and carries oxygen to all parts of the body. When there is not enough hemoglobin in the red blood cells, oxygen cannot get to all parts of the body. Organs then become starved for oxygen and are unable to function properly.

Avoid knee replacement surgery with new implant
Avoid knee replacement surgery with new implant samer kareem 1,144 Views • 3 years ago

Some of these advancements include the use of robots to perform the surgery and the use of computer mapping scanners and software and even 3D printers to make the artificial knee implant. We are also seeing a lot of different advances being made by the medical device manufacturers.Some of these changes are designed to make the devices more durable than the 10 to 20 years they are currently rated to last. This is important when younger patients who are years away from being considered elderly have a total knee replacement, they will typically need another artificial knee implanted at a later date since they are likely to outlive the implant, which doesn’t always happen with elderly patients.
