Waardenburg Syndrome
Waardenburg Syndrome samer kareem 2,271 Views • 3 years ago

Waardenburg syndrome is a group of genetic conditions that can cause hearing loss and changes in coloring (pigmentation) of the hair, skin, and eyes. Although most people with Waardenburg syndrome have normal hearing, moderate to profound hearing loss can occur in one or both ears. The hearing loss is present from birth (congenital). People with this condition often have very pale blue eyes or different colored eyes, such as one blue eye and one brown eye. Sometimes one eye has segments of two different colors. Distinctive hair coloring (such as a patch of white hair or hair that prematurely turns gray) is another common sign of the condition. The features of Waardenburg syndrome vary among affected individuals, even among people in the same family.

Temporal arteritis is a condition in which the temporal arteries, which supply blood to the head and brain, become inflamed or damaged. It is also known as cranial arteritis or giant cell arteritis. Although this condition usually occurs in the temporal arteries, it can occur in almost any medium to large artery in the body. The journal Arthritis & Rheumatology states that approximately 228,000 people in the United States are affected by temporal arteritis. According to the American College of Rheumatology, people over the age of 50 are more likely than younger people to develop the condition. Women are also more likely than men to have temporal arteritis. It is most prevalent in people of northern European or Scandinavian descent. Although the exact cause of the condition is unknown, it may be linked to the body’s autoimmune response. Also, excessive doses of antibiotics and certain severe infections have been linked to temporal arteritis. There’s no known prevention. However, once diagnosed, temporal arteritis can be treated to minimize complications.

Eosinophilic granulomatosis with polyangiitis (EGPA)—or, as it was traditionally termed, Churg-Strauss syndrome—is a rare systemic necrotizing vasculitis that affects small-to-medium-sized vessels and is associated with severe asthma and blood and tissue eosinophilia. [1] Like granulomatosis with polyangiitis (Wegener granulomatosis), and the microscopic form of periarteritis (ie, microscopic polyangiitis), EGPA is an antineutrophil cytoplasmic antibody (ANCA)–associated vasculitide. [2, 3, 4, 5] In 1951, Churg and Strauss first described the syndrome in 13 patients who had asthma, eosinophilia, granulomatous inflammation, necrotizing systemic vasculitis, and necrotizing glomerulonephritis. [3] In 1990, the American College of Rheumatology (ACR) proposed the following six criteria for the diagnosis of Churg-Strauss syndrome [6] : Asthma (wheezing, expiratory rhonchi) Eosinophilia of more than 10% in peripheral blood Paranasal sinusitis Pulmonary infiltrates (may be transient) Histological proof of vasculitis with extravascular eosinophils Mononeuritis multiplex or polyneuropathy

Reiter's Syndrome

Reiter syndrome is a type of reactive arthritis that happens as a reaction to a bacterial infection in the body. The infection usually happens in the intestines, genitals, or urinary tract.

How HIV Causes Disease
How HIV Causes Disease samer kareem 13,687 Views • 3 years ago

CD4 T-cells (a type of white blood cell) are important to your body's defence against infections. This animation describes how your immune system is weakened by the HIV virus, which targets CD4 T-cells and leads to their gradual decline in number. Low to very low levels of CD4 cells put you at risk for 'opportunistic infections' that take advantage of the body's weakened immune system.
