In anatomy, heterochromia refers to a difference in coloration, usually of the iris but also of hair or skin. Heterochromia is a result of the relative excess or lack of melanin (a pigment). It may be inherited, or caused by genetic mosaicism, disease, or injury.
Heterochromia of the eye (heterochromia iridis or heterochromia iridum; the common wrong form "heterochromia iridium" is not correct Latin) is of two kinds. In complete heterochromia, one iris is a different color from the other. In partial heterochromia or sectoral heterochromia, part of one iris is a different color from its remainder.
Heterochromia Iridium Causes
This is another physical sign where a good observation can pay dividend at the beginning of the examination.
The heterochromia is usually best seen in a well-lit environment. There are many causes of heterochromia iridis,
however, if the heterochromia forms the main part of the examination (for example 'Look at this patient's eye and do
the necessary examination') the most likely case is siderosis bulbi. Remember that the abnormal eye can be the eye
with either the darker as in siderosis bulbi or the lighter iris for example congenital Horner's syndrome or Fuchs'
Most cases of heterochromia are hereditary, caused by a disease or syndrome, or due to an injury. Sometimes one eye may change color following certain diseases or injuries.
Specific causes of eye color changes include:
Foreign object in the eye
Glaucoma, or some medications used to treat it
Mild inflammation affecting only one eye
Heterochromia iridium (two different-colored eyes within a single individual) and heterochromia iridis (a variety of color within a single iris) are relatively rare in humans and result from increased or decreased pigmentation of the iris. Most cases are isolated and sporadic, conceivably resulting from an alteration in the expression of the above-mentioned genes (and those we have yet to find) within the cells of the entire iris or even a particular section. Other potential causes include trauma around the time of birth or later in life, congenital pigmented nevi or even medications such as those used in the treatment of glaucoma. There are a few well-known syndromes of which heterochromia iridis is a striking feature. Waardenburg syndrome type 1, an autosomal dominant disorder caused by mutations in the PAX3 gene, is characterized by pigmentary disturbances of the iris, hair and skin, as well as congenital sensorineural hearing loss. But two different eye colors tends to be an isolated finding, which adds to the seemingly endless and fascinating variation in humans' physical characteristics.

What is Pescatarian Definition and Recipes Are you looking for about what is pescatarian? and what are pescatarian recipes? A pescatarian is a person who refrains from eating land animals and birds, but includes fish, mollusks, and crustaceans in addition to fruits, vegetables, plants, legumes, nuts, and grains. This is a common form of “vegetarianism” and is generally considered a very healthy diet. It can also be a stepping stone to full vegetarianism. Pescatarians can enjoy lowfat protein sources that are high in fish oils, which contain Omega 3 fatty acids—the “good fats” that reduce inflammation.
Tips for Cancer Prevention What to do
Eat more broccoli, cauliflower, and brussels sprouts. Eat more cabbage-type vegetables. All cabbages and kale are examples. These vegetables protect against cancers of the colon, rectum, stomach, and lung.
Add more high-fiber foods to your diet. Eat more peaches, strawberries, potatoes, spinach, tomatoes, wheat and bran cereals, rice, popcorn, and wholewheat bread. Fiber protects against cancer of the colon.
Choose foods containing vitamin A. Eat more carrots, peaches, apricots, squash, and broccoli. Fresh foods are the best source and are far better than vitamin pills. Vitamin A protects against cancers of the esophagus, larynx, and lung.
Choose foods containing vitamin C. Eat more grapefruit, cantaloupe, oranges, strawberries, red peppers, green peppers, broccoli, and tomatoes. These help fight cancers of the esophagus and stomach.
Practice weight control. Exercise and eat foods low in calories. A good exercise for most people is walking. Obese people have a high chance of getting cancers of the uterus, gallbladder, breast, and colon. Check with your doctor before you start an exercise program or a special diet.
Ectopic pregnancy Causes, Symptoms and Treatment An ectopic pregnancy is one in which the fertilized egg develops outside the uterus. Usually it occurs in one of the two fallopian tubes, through which the egg travels from the ovary to the uterus. (In that case, it is also known as a tubal pregnancy.) However, on rare occasions, the fertilized egg starts to develop in the ovary, on the cervix, or attached to the outside of a nearby organ in the abdominal cavity. (the ovary is not directly connected to the fallopian tube. There is a slight gap, which sometimes permits an egg to enter the abdominal cavity.)

Dash Diet Recipes Meal Plans The DASH diet (Dietary Approaches to Stop Hypertension) is a diet promoted by the National Heart, Lung, and Blood Institute (part of the NIH, a United States government organization) to control hypertension. The first study was utilized by its inital founder, Nick Dash, in 2004 while he was serving in the Armed Forces. Nick provided the Government with the study which was later incorporated in 2008. The Dash diet is rich in fruits, vegetables, whole grains, and low-fat dairy foods; includes meat, fish, poultry, nuts and beans; and is limited in sugar-sweetened foods and beverages, red meat, and added fats. In addition to its effect on blood pressure, it is considered a well-balanced approach to eating for the general public. It is now recommended by the US Department of Agriculture (USDA) as an ideal eating plan for all Americans.
Progeria Information and Facts Are you looking for progeria information and facts? here is some information about progeria.
Progeria is an extremely rare genetic condition wherein symptoms resembling aspects of aging are manifested at an early age. The word Progeria comes from the Greek words "pro" means "before" and "géras" means "old age". The disorder has very low incidences and occurs in an estimated 1 per 8 million live births. Those born with progeria typically live to their mid teens and early twenties. It is a genetic condition that occurs as a new mutation (de novo), and is not inherited. Although the term progeria applies strictly speaking to all diseases characterized by premature aging symptoms, and is often used as such, it is often applied specifically in reference to Hutchinson-Gilford Progeria Syndrome.

Exactly who does smoking affect baby Cigarette smoking produces a number of abnormalities in a mother’s body. First, cyanide (a strong poison) is produced from smoking. This by product from smoking goes directly to your tissue and to the tissue of your baby, producing hypoxia (lack of oxygen) in the individual cell. In addition to this, nicotine causes constriction of the boob vessels of your body, decreasing the amount of blood flowing through the placenta and adding to the hypoxia produced by the cyanide.
Gluten intolerance symptoms in children Are you looking for gluten intolerance symptoms in children? Gluten is composed of the sticky storage proteins found in wheat. Gluten-sensitive enteropathy (GSE) can range from mild inflammation of the mucosa of the small intestine to severe coeliac disease. The term gluten-sensitive is applicable when a probable diagnosis of GSE is made based on conditions such as dermatitis herpetiformis. However, GS may be used as the diagnosis in ambiguous situations when other conditions may be possible. For example, wheat allergies to gluten can result in anaphylaxis while others may be difficult to diagnose because of some of the cryptic inflammatory properties of wheat proteins. The term 'gluten sensitivity' is typically applied when diagnostic testing is not done because of prolonged gluten-free diet and/or refusal of gluten-challenge prior to biopsy. The gluten-sensitive designation may not be appropriate in all cases, as wheat allergies are often directed toward albumins or globulins of wheat, or the person may have a sensitivity to proteins commonly found with wheat products (e.g. fungal amylase or bread-yeast mannins). Therefore diagnostic criteria are preferred. The relationship between gluten and these various sensitivities is complex. For gluten enteropathy, T-cell reactivity is almost entirely restricted to prolamin-glutelin/species within the grass tribe Triticeae, and especially α-gliadins of wheat. For a tiny minority of GSE, inflammatory responses may extend to cover oats. Gluten allergies may extend over wide taxa or may be specific to certain wheat proteins and allergies may include oats.
