Cerebral Aneurysm
Cerebral Aneurysm samer kareem 2,076 Views • 2 years ago

What is an Aneurysm? A cerebral or intracranial aneurysm is an abnormal focal dilation of an artery in the brain that results from a weakening of the inner muscular layer (the intima) of a blood vessel wall. The vessel develops a "blister-like" dilation that can become thin and rupture without warning. The resultant bleeding into the space around the brain is called a subarachnoid hemorrhage (SAH). This kind of hemorrhage can lead to a stroke, coma, and/or death. Aneurysms are usually found at the base of the brain just inside the skull, in an area called the subarachnoid space. In fact, 90 percent of SAHs are attributed to ruptured cerebral aneurysms and the two terms are often used synonymously.

CIN is a rare disorder and occurs when kidney problems are caused by the use of certain contrast dyes. In most cases contrast dyes used in tests, such as CT (computerized tomography) and angiograms, have no reported problems. About 2 percent of people receiving dyes can develop CIN. However, the risk for CIN can increase for people with diabetes, a history of heart and blood diseases, and chronic kidney disease (CKD). For example, the risk of CIN in people with advanced CKD (glomerular filtration rate (GFR) below 30 mL/min/1.73m2), increases to 30 to 40 percent. The risk of CIN in people with both CKD and diabetes is 20 to 50 percent.

Ankylosing Spondylitis samer kareem 2,546 Views • 2 years ago

Ankylosing spondylitis is an inflammatory disease that, over time, can cause some of the vertebrae in your spine to fuse. This fusing makes the spine less flexible and can result in a hunched-forward posture. If ribs are affected, it can be difficult to breathe deeply. Ankylosing spondylitis affects men more often than women. Signs and symptoms typically begin in early adulthood. Inflammation also can occur in other parts of your body — most commonly, your eyes. There is no cure for ankylosing spondylitis, but treatments can lessen your symptoms and possibly slow progression of the disease.

Vertigo is a sensation of spinning. If you have these dizzy spells, you might feel like you are spinning or that the world around you is spinning. Causes of Vertigo Vertigo is often caused by an inner ear problem. Some of the most common causes include: BPPV. These initials stand for benign paroxysmal positional vertigo. BPPV occurs when tiny calcium particles (canaliths) clump up in canals of the inner ear. The inner ear sends signals to the brain about head and body movements relative to gravity. It helps you keep your balance. BPPV can occur for no known reason and may be associated with age. Meniere's disease.

Face transplantation surgery
Face transplantation surgery samer kareem 16,060 Views • 2 years ago

Face transplant candidates go through an extensive screening process that is likely to last several months. This screening includes a psychiatric and social support evaluation and a series of imaging tests to help determine a patient’s physical and mental readiness for the procedure. If, upon completion of the screening process, it is determined that a patient is a suitable candidate, we will place the patient on a transplant waiting list. We will then begin working with the New England Organ Bank (NEOB) team to find a donor who matches the recipient’s tissue requirements – e.g., similar age, right blood type. This search could take many months, and, if a suitable donor is not found within one year, we will speak with the patient to determine whether they’re willing to continue waiting. When a donor is found, we will immediately inform the patient about when to arrive at the hospital for the operation. As the timing for this type of procedure is extremely important, patients are expected to be readily available, i.e., reside within a 12-hour travel radius of BWH.

What is CMV?
What is CMV? samer kareem 2,490 Views • 2 years ago

Is it possible to prevent cytomegalovirus infection? Is there a CMV vaccine? Cytomegalovirus (CMV) infection facts CMV is a common virus in the same family as herpesvirus, and it can infect anyone. CMV is spread by direct contact of body fluids, such as saliva, blood, urine, semen, vaginal fluids, and breast milk. Thus breastfeeding, blood transfusions, organ transplants, and sexual contact are possible modes of transmission. Most healthy people do not experience any symptoms when infected with CMV, and it does not pose a serious health concern. A majority of adults have antibodies consistent with past infection. Most healthy children and adults who do have symptoms will recover from CMV infection without complications and do not require antiviral treatment.
