The effects of Behcet's disease vary from person to person and may clear up on their own. Treatment involves medications to reduce the signs and symptoms of Behcet's disease and to prevent serious complications, such as blindness.

Vascular dementia
Vascular dementia samer kareem 1,711 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

Digoxin is used to treat heart failure, usually along with other medications. It is also used to treat a certain type of irregular heartbeat (chronic atrial fibrillation). Treating heart failure may help maintain your ability to walk and exercise and may improve the strength of your heart. Treating an irregular heartbeat can decrease the risk for blood clots, an effect that may reduce your risk for a heart attack or stroke.

SPERMATOCELE vs EPIDIDIMAL CYST
SPERMATOCELE vs EPIDIDIMAL CYST samer kareem 2,967 Views • 2 years ago

The epididymis is a long coiled tube that lies above and behind each testicle. The epididymis collects and transports sperm from the testis to the vas deferens (tubes that transport sperm to the urethra). An epididymal cyst is a cyst-like mass in the epididymis that contains clear fluid. Typically, epididymal cysts and spermatoceles do not cause symptoms. When discovered, the epididymal cyst is usually about the size of a pea and feels separate from the top of the testis. Spermatoceles typically arise from the head of the epididymis, and are felt on the top portion of the testicle. Epididymal cysts and spermatoceles are often incidental findings on testicular self-examination or routine physical examination. It is important that any mass noted in the scrotum be examined by a urologist in order to obtain an accurate diagnosis, especially a mass on the testicle itself. Our team in the Division of Urology will typically be able to confirm the diagnosis on physical exam. However, a scrotal ultrasound may also be used in order to rule out other conditions.

Sleep Apnea Surgery
Sleep Apnea Surgery samer kareem 1,569 Views • 2 years ago

This procedure, and other types of soft palate surgery, targets the back of the roof of your mouth. It involves removing and repositioning excess tissue in the throat to make the airway wider. The surgeon can trim down your soft palate and uvula, remove your tonsils, and reposition some of the muscles of the soft palate. UPPP and other soft palate procedures are the most common type of surgery for sleep apnea. But UPPP alone is unlikely to cure moderate to severe sleep apnea. It may be combined with surgeries that target other sites in the upper airway.

Partial Medial Meniscectomy Arthroscopغ
Partial Medial Meniscectomy Arthroscopغ samer kareem 1,305 Views • 2 years ago

An arthroscopic meniscectomy is a procedure to remove some or all of a meniscus from the tibio-femoral joint of the knee using arthroscopic (aka 'keyhole') surgery. In a complete meniscectomy the meniscus including the meniscal rim is removed. A partial meniscectomy involves partial removal of the meniscus. This may vary from minor trimming of a frayed edge to anything short of removing the rim. This is a minimally invasive procedure often done as day suas an outpatient in a one-day clinic [1] This procedure is performed when a meniscal tear is too large to be corrected by a surgical meniscal repair.[1] When non-operative therapy provides some degree of symptom relief over the long-term, these benefits may wane with continued meniscal degeneration. In such patients, arthroscopic partial meniscectomy can be effective in improving patient quality of life.

These air sacs make up most of the lung tissue. Lung diseases affecting the alveoli include: Pneumonia: An infection of the alveoli, usually by bacteria. Tuberculosis: A slowly progressive pneumonia caused by the bacteria Mycobacterium tuberculosis. Chronic respiratory diseases are chronic diseases of the airways and other structures of the lung. Some of the most common are: asthma, chronic obstructive pulmonary disease, occupational lung diseases and pulmonary hypertension.

Bovine Respiratory Disease
Bovine Respiratory Disease samer kareem 1,246 Views • 2 years ago

Bovine respiratory disease (BRD) has a multifactorial etiology and develops as a result of complex interactions between environmental factors, host factors, and pathogens. Environmental factors (eg, weaning, transport, commingling, crowding, inclement weather, dust, and inadequate ventilation) serve as stressors that adversely affect the immune and nonimmune defense mechanisms of the host. In addition, certain environmental factors (eg, crowding and inadequate ventilation) can enhance the transmission of infectious agents among animals. Many infectious agents have been associated with BRD. An initial pathogen (eg, a virus) may alter the animal’s defense mechanisms, allowing colonization of the lower respiratory tract by bacteria.

Atherosclerosis is a process in which blood, fats such as cholesterol, and other substances build up on your artery walls. Eventually, deposits called plaques may form. The deposits may narrow — or block — your arteries. These plaques can also rupture, causing a blood clot.
