Cortisol and Glucocorticoids
Cortisol and Glucocorticoids samer kareem 3,680 Views • 3 years ago

The vast majority of glucocorticoid activity in most mammals is from cortisol, also known as hydrocortisone. Corticosterone, the major glucocorticoid in rodents, is another glucocorticoid. Cortisol binds to the glucocorticoid receptor in the cytoplasm and the hormone-receptor complex is then translocated into the nucleus, where it binds to its DNA response element and modulates transcription from a battery of genes, leading to changes in the cell's phenotype. Only about 10% of circulating cortisol is free. The remaining majority circulates bound to plasma proteins, particularly corticosteroid-binding globulin (transcortin). This protein binding likely decreases the metabolic clearance rate of glucocorticoids and, because the bound steroid is not biologically active, tends to act as a buffer and blunt wild fluctuations in cortisol concentration.

Heparin Induced Thrombocytopenia (HIT)
Heparin Induced Thrombocytopenia (HIT) samer kareem 9,412 Views • 3 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.

Rabies
Rabies samer kareem 7,306 Views • 3 years ago

In developing countries, domestic animals (eg, dogs) are common sources of infection. In the United States, bats and wild animals (eg, raccoons) are the most common reservoirs of infection. The acquisition of rabies from bats can occur from an unrecognized bite or a scratch, and possibly by inhalation of aerosolized viral particles. Bats are found in all states except Hawaii, and spelunking (cave exploration) is a risk factor for rabies acquisition from bats.

Kidney Transplant & Dialysis
Kidney Transplant & Dialysis samer kareem 6,992 Views • 3 years ago

Dialysis and kidney transplantation are treatments for severe kidney failure, also called kidney (or renal) failure, stage 5 chronic kidney disease, and end-stage kidney (or renal) disease. There are two types of dialysis: hemodialysis and peritoneal dialysis. When the kidneys are no longer working effectively, waste products, electrolytes, and fluid build up in the blood. Dialysis takes over a portion of the function of the failing kidneys to remove the fluid and waste products. Kidney transplantation can more completely take over the function of the failing kidneys.

Most people with TS are not significantly impaired by their symptoms and therefore do not require treatment with medication. However, several medications are available to control TS symptoms that interfere with functioning. Except in more severe cases when tics are sometimes painful, the main reasons for medication are to improve appearance and lessen embarrassing social interactions. As with all medications, there are possible side effects that should be monitored carefully by the physician. Patients should always be included in the decision to take medication, as they are the best judge of how disruptive the symptoms are to them. Early diagnosis and treatment are crucial to help the person with TS cope with his or her condition. Often, people make fun of a person with TS. Parents of children with TS also may find it difficult to cope with their child's behavior. When people with TS are diagnosed correctly and treated for the condition early, they can learn to cope with their disorder and accept that they are ok and normal.

Skin grafting is a surgical procedure that involves removing the skin from one area of the body and moving it, or transplanting it, to a different area of the body. This surgery may be done if a part of your body has lost its protective covering of skin due to burns, injury, or illness. Skin grafts are performed in a hospital. Most skin grafts are done using general anesthesia, which means you’ll be asleep throughout the procedure and won’t feel any pain.

Paracentesis is a procedure to take out fluid that has collected in the belly (peritoneal fluid). This fluid buildup is called ascites camera.gif. Ascites may be caused by infection, inflammation, an injury, or other conditions, such as cirrhosis or cancer. The fluid is taken out using a long, thin needle put through the belly. The fluid is sent to a lab and studied to find the cause of the fluid buildup. Paracentesis also may be done to take the fluid out to relieve belly pressure or pain in people with cancer or cirrhosis.

http://vitiligo-home-remedies.plus101.com ---- white spots on skin, small white spots on face, what causes white spots on skin, vitiligo. The Link Between Vitiligo and Auto Immune Disorders. If you suffer with Vitiligo, a condition that strips your skin of its natural pigment or coloring, the odds are good that you are also battling some sort of autoimmune disorder. It took years for doctors to connect the two disorders, but recent research shows that at least 20 percent of Vitiligo suffers also get autoimmune thyroid disease, and that's juts the beginning. Many more suffer a multitude of other disorders. Until recently, the link between the Vitiligo and autoimmune problems were not clear. Doctors seemed to see a link, but nothing substantial could be proven. Until now. In march 2013, The National Institute's of Health's National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) announced an amazing discovery: a connection between a specific gene named NALP1, Vitiligo and a host of autoimmune diseases including thyroid disease, pernicious anemia, rheumatoid arthritis, lupus and Addison's Disease. According to lead researcher, Richard Spritz M.D., the discovery of this gene may make newer, more effective Vitiligo treatments possible within the next few years. But that's not all. It will also be able to help treat certain auto immune disorders. By finding ways to block the inflammatory response of the NALP1 gene, doctors may some day be able to cure certain autoimmune disorders. A long-term solution for vitiligo should address the internal causes of vitiligo by tackling all vitiligo contributing factors. Only by controlling the nutritional, hormonal, psychological and environmental triggers of vitiligo, using a multidimensional and holistic approach to healing you can reverse the "internal vitiligo environment"- the only, safe, natural and effective way you could ever achieve lasting vitiligo freedom.
