Wegener granulomatosis and microscopic polyangiitis samer kareem 9,979 Views • 2 years ago

Microscopic polyangiitis (MPA) is vasculitis of small vessels. It was initially considered as a microscopic form of polyarteritis nodosa (PAN). In 1990, the American College of Rheumatology developed classification criteria for several types of systemic vasculitis but did not distinguish between polyarteritis nodosa and microscopic polyarteritis nodosa. [1] In 1994, a group of experts held an international consensus conference in Chapel Hill, North Carolina, to attempt to redefine the classification of small vessel vasculitides. [2, 3]

Basics of Multiple Endocrine Neoplasia samer kareem 5,094 Views • 2 years ago

Multiple endocrine neoplasia is a group of disorders that affect the body's network of hormone-producing glands (the endocrine system). Hormones are chemical messengers that travel through the bloodstream and regulate the function of cells and tissues throughout the body. Multiple endocrine neoplasia typically involves tumors (neoplasia) in at least two endocrine glands; tumors can also develop in other organs and tissues. These growths can be noncancerous (benign) or cancerous (malignant). If the tumors become cancerous, the condition can be life-threatening.

Why You Got Fat
Why You Got Fat samer kareem 26,597 Views • 2 years ago

The usual reason given for people getting fat is that they eat too much and/or exercise too little. That reflects one of the basic laws of thermodynamics—I forget which one. The amount of energy you put into a system minus the energy you take out has to be stored somewhere i.e. FAT! This formulation—true though it is—does not entirely explain obesity since some people seem to eat more than fat people and exercise no more than these same fat people, and yet they are not fat! Chalking this fact up to the general perversity of the universe is not sufficient explanation. Other factors must come into play. I mention below some of the ideas thoughtful people have proposed to explain why fat people become fat:

What is Root Canal?
What is Root Canal? samer kareem 8,019 Views • 2 years ago

Has your dentist or endodontist told you that you need root canal treatment? If so, you're not alone. Millions of teeth are treated and saved each year with root canal, or endodontic, treatment. Remember, root canal treatment doesn't cause pain, it relieves it. Watch our videos below to learn more! Inside the tooth, under the white enamel and a hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves and connective tissue, and helps to grow the root of your tooth during development. In a fully developed tooth, the tooth can survive without the pulp because the tooth continues to be nourished by the tissues surrounding it.

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.
