Vascular dementia
Vascular dementia samer kareem 1,720 Views • 2 years ago

Vascular dementia is a general term describing problems with reasoning, planning, judgment, memory and other thought processes caused by brain damage from impaired blood flow to your brain. You can develop vascular dementia after a stroke blocks an artery in your brain, but strokes don't always cause vascular dementia. Whether a stroke affects your thinking and reasoning depends on your stroke's severity and location. Vascular dementia also can result from other conditions that damage blood vessels and reduce circulation, depriving your brain of vital oxygen and nutrients

Boxer's Knuckle
Boxer's Knuckle samer kareem 1,996 Views • 2 years ago

Boxer’s Knuckle is an injury to the structures around the first knuckle of a finger, also known as the metacarpophalangeal joint (MPJ). The skin, extensor tendon, ligaments, joint cartilage, and the bone of the metacarpal head may all be involved. Repeated impacts to the extensor tendon over the knuckle causes Hypertrophic Interstitial Tendonosis, or HIT Syndrome. This is a thickening, weakening, inflammation, and scarring of the extensor tendon.

Hepatitis B Symptoms and Treatment
Hepatitis B Symptoms and Treatment samer kareem 1,475 Views • 2 years ago

Hepatitis B is a liver infection caused by the Hepatitis B virus (HBV). Hepatitis B is transmitted when blood, semen, or another body fluid from a person infected with the Hepatitis B virus enters the body of someone who is not infected. This can happen through sexual contact; sharing needles, syringes, or other drug-injection equipment; or from mother to baby at birth. For some people, hepatitis B is an acute, or short-term, illness but for others, it can become a long-term, chronic infection. Risk for chronic infection is related to age at infection: approximately 90% of infected infants become chronically infected, compared with 2%–6% of adults. Chronic Hepatitis B can lead to serious health issues, like cirrhosis or liver cancer. The best way to prevent Hepatitis B is by getting vaccinated.

Rotator Cuff Tears
Rotator Cuff Tears samer kareem 1,493 Views • 2 years ago

A rotator cuff tear is a common injury, especially in sports like baseball or tennis, or in jobs like painting or cleaning windows. It usually happens over time from normal wear and tear, or if you repeat the same arm motion over and over. But it also can happen suddenly if you fall on your arm or lift something heavy. Your rotator cuff is a group of four muscles and tendons that stabilize your shoulder joint and let you lift and rotate your arms. There are two kinds of rotator cuff tears. A partial tear is when the tendon that protects the top of your shoulder is frayed or damaged. The other is a complete tear. That’s one that goes all the way through the tendon or pulls the tendon off the bone.

Multiple Myeloma Mechanism of Action
Multiple Myeloma Mechanism of Action samer kareem 1,505 Views • 2 years ago

The pathobiology of MM is complex and the root underlying cause of myeloma is the multistep genetic changes in the postgerminal center B cell. In addition, the bone marrow microenvironment plays a crucial role.[2] The interaction between myeloma cells and the microenvironment is mediated through adhesive interactions via cell-surface receptors, paracrine loops involving several cytokines, such as IL-6, VEGF and IL-10, and suppression of cell-mediated immunity.[2–4] IMiDs modulate many of these interactions leading to decreased myeloma cell growth and survival. Thalidomide was the first IMiD introduced to treat MM. It was initially synthesized in Germany in the late 1950s to treat insomnia and morning sickness. It was withdrawn from the market in 1961 because of its teratogenic effects. Its immunomodulatory properties were realized when it was observed to improve erythema nodosum leprosum, a painful immunologic reaction of leprosy, leading to its approval by the FDA in 1998 with tight prescribing and marketing regulations. Subsequent research showed the diverse mechanism of action of thalidomide including its immunomodulatory effect by inhibition of de novo IgM antibody synthesis,[5] modulation of the T-cell subset by increasing the T-helper cells, inhibitory effects on the TNF-α and antiangiogenic activity leading to its use in MM. Significantly higher response rates in combination with dexamethasone led to its approval in the treatment of newly diagnosed MM in 2006. Lenalidomide, a second-generation IMiD, was developed from the structural backbone of the thalidomide molecule by the addition of an amino group (NH2-) at position 4 of the phthaloyl ring and removal of the carbonyl group (C = O) of the 4-amino-substituted phthaloyl ring (Table 1).[6] In addition to immunomodulatory effects, other mechanisms of action have been described such as direct cytotoxicity via induction of apoptosis, inhibition of cell adhesion molecules and inhibition of growth signals that promote bone marrow angiogenesis

Silicosis Disease
Silicosis Disease samer kareem 1,521 Views • 2 years ago

www.lung.org > Lung Health and Diseases > Lung Disease Lookup > Silicosis Learn About Silicosis Silicosis is a lung disease caused by breathing in tiny bits of silica, a mineral that is part of sand, rock, and mineral ores such as quartz. It mostly affects workers exposed to silica dust in occupations such mining, glass manufacturing, and foundry work. Over time, exposure to silica particles causes scarring in the lungs, which can harm your ability to breathe. Key Facts There are three types of silicosis: acute, chronic, and accelerated. It occurs in workers from mines, foundries, sandblasting, and glass manufacturing. About 2 million US workers remain potentially exposed to occupational silica. There is no cure for silicosis, but it can be prevented. What Is Silicosis? There are three types of silicosis: Acute silicosis, which causes cough, weight loss, and fatigue within a few weeks or years of exposure to inhaled silica. Chronic silicosis, which appears 10 to 30 years after exposure and can affect upper lungs and sometimes cause extensive scarring. Accelerated silicosis, which occurs within 10 years of high-level exposure. Silicosis can develop within a few weeks to even decades after exposure. When people breathe silica dust, they inhale tiny particles of the mineral silica. This silica dust can cause fluid buildup and scar tissue in the lungs that cuts down your ability to breathe. This can lead to lung scarring and cough, weight loss, and fatigue.

Retina Laser Surgery
Retina Laser Surgery samer kareem 1,447 Views • 2 years ago

Most retinal tears need to be treated by sealing the retina to the back wall of the eye with laser surgery or cryotherapy (a freezing treatment). Both of these procedures create a scar that helps seal the retina to the back of the eye. This prevents fluid from traveling through the tear and under the retina, which usually prevents the retina from detaching. These treatments cause little or no discomfort and may be performed in your ophthalmologist’s office. With laser surgery, your ophthalmologist uses a laser to make small burns around the retinal tear. The scarring that results seals the retina to the underlying tissue, helping to prevent a retinal detachment.

Brain Injury
Brain Injury samer kareem 9,574 Views • 2 years ago

Traumatic Brain Injury (TBI) TBI is defined as an alteration in brain function, or other evidence of brain pathology, caused by an external force. Adopted by the Brain Injury Association Board of Directors in 2011. This definition is not intended as an exclusive statement of the population served by the Brain Injury Association of America. Acquired Brain Injury An acquired brain injury is an injury to the brain, which is not hereditary, congenital, degenerative, or induced by birth trauma. An acquired brain injury is an injury to the brain that has occurred after birth. There is sometimes confusion about what is considered an acquired brain injury. By definition, any traumatic brain injury (e.g. from a motor vehicle accident or assault) could be considered an acquired brain injury. In the field of brain injury, acquired brain injuries are typically considered any injury that is non traumatic. Examples of acquired brain injury include stroke, near drowning, hypoxic or anoxic brain injury, tumor, neurotoxins, electric shock or lightning strike.
