What Causes Strokes
What Causes Strokes samer kareem 6,103 Views • 2 years ago

A stroke occurs when the blood supply to your brain is interrupted or reduced. This deprives your brain of oxygen and nutrients, which can cause your brain cells to die. A stroke may be caused by a blocked artery (ischemic stroke) or the leaking or bursting of a blood vessel (hemorrhagic stroke)

What Happens When We Die
What Happens When We Die samer kareem 8,719 Views • 2 years ago

There's only one group of people who really know what happens when you die: the dead. And since the dead won't be revealing their secrets anytime soon, it's up to scientists to explain what happens when a person dies. Death, just like life, is a process, scientists say. The first stage of this process is known as clinical death. It lasts from four to six minutes, beginning when a person stops breathing and the heart stops pumping blood. During this time, there may be enough oxygen in the brain that no permanent brain damage occurs. Other organs, such as the kidneys and eyes, also remain alive throughout clinical death.

Gastroparesis & Diabetes
Gastroparesis & Diabetes samer kareem 12,773 Views • 2 years ago

Gastroparesis is a disorder affecting people with both type 1 and type 2 diabetes in which the stomach takes too long to empty its contents (delayed gastric emptying). The vagus nerve controls the movement of food through the digestive tract. If the vagus nerve is damaged or stops working, the muscles of the stomach and intestines do not work normally, and the movement of food is slowed or stopped. Just as with other types of neuropathy, diabetes can damage the vagus nerve if blood glucose levels remain high over a long period of time. High blood glucose causes chemical changes in nerves and damages the blood vessels that carry oxygen and nutrients to the nerves. - See more at: http://www.diabetes.org/living-with-diabetes/complications/gastroparesis.html?referrer=https://www.google.com/#sthash.rTgZiOuM.dpuf

Spermatogenesis
Spermatogenesis samer kareem 12,598 Views • 2 years ago

Knee replacement, also called arthroplasty, is a surgical procedure to resurface a knee damaged by arthritis. Metal and plastic parts are used to cap the ends of the bones that form the knee joint, along with the kneecap. This surgery may be considered for someone who has severe arthritis or a severe knee injury.

Robotic Partial Nephrectomy
Robotic Partial Nephrectomy samer kareem 2,303 Views • 2 years ago

The robotic approach to renal surgery, particularly partial nephrectomy, has some inherent challenges, and some familiarity with the da Vinci robotic system is necessary. The surgeon must gain an understanding of the robotic arm movements and range of motion, especially in relation to the clutch and camera. The advent of robotically assisted prostatectomy in 2001 [23] paved the way for widespread accessibility to the da Vinci robotic unit and its application to renal surgery. Since that time, at least one multi-institutional survey has demonstrated superiority of the robotic approach when compared to laparoscopic for outcomes of blood loss, hospital stay and a substantially shorter warm ischemia time, while maintaining equivalence in positive margin rate, operative time and complications. [11] A transperitoneal approach is most commonly used. Prior abdominal operation is not necessarily a contraindication to this procedure, but access should be approached with regard for previous operation(s) by an experienced team.

Edwards Syndrome
Edwards Syndrome samer kareem 3,925 Views • 2 years ago

Trisomy 18, also called Edwards syndrome, is a chromosomal condition associated with abnormalities in many parts of the body. Individuals with trisomy 18 often have slow growth before birth (intrauterine growth retardation) and a low birth weight. Affected individuals may have heart defects and abnormalities of other organs that develop before birth. Other features of trisomy 18 include a small, abnormally shaped head; a small jaw and mouth; and clenched fists with overlapping fingers. Due to the presence of several life-threatening medical problems, many individuals with trisomy 18 die before birth or within their first month. Five to 10 percent of children with this condition live past their first year, and these children often have severe intellectual disability.

Cushing's Disease
Cushing's Disease samer kareem 5,964 Views • 2 years ago

Cushing's disease is a serious condition of an excess of the steroid hormone cortisol in the blood level caused by a pituitary tumor secreting adrenocorticotropic hormone (ACTH). ACTH is a hormone produced by the normal pituitary gland. ACTH stimulates the adrenal glands (located on top of the kidneys) to produce cortisol, commonly referred to as the stress hormone.

Heparin Induced Thrombocytopenia (HIT)
Heparin Induced Thrombocytopenia (HIT) samer kareem 9,368 Views • 2 years ago

All forms of heparin (including low-molecular-weight heparin such as enoxaparin) must be stopped immediately in patients with suspected heparin-induced thrombocytopenia (HIT) while awaiting diagnostic confirmation. Patients with HIT remain at high risk of thrombosis even after discontinuation of heparin. Therefore, an alternate, rapidly acting, non-heparin anticoagulant such as direct thrombin inhibitor (eg, argatroban, bivalirudin) must be started immediately.
