Cluster Headaches
Cluster Headaches samer kareem 6,684 Views • 3 years ago

Cluster headaches, occur in cyclical patterns or clusters, are one of the most painful types of headache. A cluster headache commonly awakens you in the middle of the night with intense pain in or around one eye on one side of your head. Bouts of frequent attacks, known as cluster periods, can last from weeks to months, usually followed by remission periods when the headaches stop. During remission, no headaches occur for months and sometimes even years. Fortunately, cluster headache is rare and not life-threatening. Treatments can make cluster headache attacks shorter and less severe. In addition, medications can reduce the number of cluster headaches.

Transcatheter Aortic Valve Implantation
Transcatheter Aortic Valve Implantation samer kareem 5,574 Views • 3 years ago

This minimally invasive surgical procedure repairs the valve without removing the old, damaged valve. Instead, it wedges a replacement valve into the aortic valve’s place. The surgery may be called a transcatheter aortic valve replacement (TAVR) or transcatheter aortic valve implantation (TAVI).

Infarction
Infarction samer kareem 1,848 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.

Treatment of Myocardial Infarction samer kareem 9,888 Views • 3 years ago

Blood clots form in an already-narrowed artery and block the flow of oxygen-rich blood to the heart muscle. When taken during a heart attack, aspirin slows clotting and decreases the size of the blood clot that is forming. After a heart attack. Aspirin can help prevent a second heart attack.

Amnesia
Amnesia samer kareem 5,658 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.
