Infarction
Infarction samer kareem 1,849 Views • 3 years ago

The occurrence and extent of cerebral infarction is determined by three basic factors: i) site of arterial occlusion, ii) the rapidity of arterial occlusion, and iii) the presence or absence of collateral circulation. Grossly, infarcts are usually divided into pale (non-hemorrhagic) and hemorrhagic types. Infarcts evolve over time, thus their gross appearance gives a clue to when they occurred. The temporal evolution of an infarct occurs in three stages: i) acute (1 day – 1 week) – the involved area is soft and edematous and there is a blurring of anatomic detail; ii) subacute (1 week – 1 month) – there is obvious tissue destruction and liquefactive necrosis of the involved brain; iii) chronic (>1 month) – the damaged tissue has been phagocytized and there is cavition with surrounding gliosis. Microscopically there is also a temporal evolution of cerebral infarcts. During the earliest phase of infarction (0-48 hours) chromatolysis and swollen eosinophilic neurons are seen. Neuronal cell necrosis and an acute inflammatory response are usually seen from 24-72 hours. This response is typically followed by an influx of mononuclear cells which begin to phagocytize necrotic debris (3-5 days). From 1-2 weeks after the infarct there is vascular proliferation and reactive astrocytosis. Over time (>1 month) the necrotic tissue will be completely removed and a cystic cavity surrounded by a glial scar will be formed.

Erythrocyte Sedimentation Rate
Erythrocyte Sedimentation Rate samer kareem 5,600 Views • 3 years ago

Sed rate, or erythrocyte sedimentation rate ( ESR ), is a blood test that can reveal inflammatory activity in your body.

Amnesia
Amnesia samer kareem 5,659 Views • 3 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.

Dental Implant
Dental Implant samer kareem 7,687 Views • 3 years ago

If you are self-conscious because you have missing teeth, wear dentures that are uncomfortable or don't want to have good tooth structure removed to make a bridge, talk to your dentist to see if dental implants are an option for you. Dental implants are a popular and effective way to replace missing teeth and are designed to blend in with your other teeth. They are an excellent long-term option for restoring your smile. In fact, the development and use of implants is one of the biggest advances in dentistry in the past 40 years. Dental implants are made up of titanium and other materials that are compatible with the human body. They are posts that are surgically placed in the upper or lower jaw, where they function as a sturdy anchor for replacement teeth.

Sleep Apnea Study
Sleep Apnea Study samer kareem 3,933 Views • 3 years ago

If you suspect that you have sleep apnea, the usual first step is to discuss your suspicions with your primary care physician. If you don’t have a primary care physician, you can go directly to a clinician who is a sleep specialist. But check your health care insurance coverage first. Some policies require you to see a primary care physician first, and some policies limit the sleep centers and testing facilities whose services they will pay for. Unfortunately, you may discover that your policy offers limited or no coverage for the diagnosis and treatment of sleep apnea, in which case you may wish to switch insurers if and when you can.
