What is Graves' Disease ?

According to www.medicalnewstoday.com, Graves' disease is defined as an autoimmune disease, in which the patient's own immune system started to attack its own thyroid gland. When this happens, it will trigger the gland to produce large amount of thyroxine. Thyroxine (T4) is a hormone, produced by the thyroid gland which serves to help regulating growth and controlling metabolism in the body. Contrary, graves' disease is a form of hyperthyroidism. When thyroxine levels are high, the patient's metabolic rate increases. This, in turn will affect one's physical appearance, as well as their moods.

However, it seems to affect more on women, especially those, aged 20 years, or more. At this moment, there is no known medication, or treatment to stop the patient's immune system from attacking their thyroid gland. Nevertheless, treatments do exist ... which can ease the symptoms and bring down the production of thyroxine.

The purpose of the immune systems is to attack pathogens, organisms and substances that are existing in our body, especially bacterias, viruses, parasites, cancerous cells and fungi. But, if the immune system starts to attack good tissues in the body, this will become an auto-immune disease. Even medical experts are still unsure, why autoimmune diseases occur. Strangely, when it affects the thyroid gland, it does not damage it, but instead, it will cause the thyroid gland to produce excessive amounts of thyroid hormone. The thyroid gland is part of the endocrine system and is located in the neck (below the Adam's apple). It produces hormones which help to regulate growth and the rate of chemical reactions, by which the body uses energy. The thyroid gland produces thyroxine and triiodothyronine. Thyroxine affects many body systems and has a key role in regulating our body's metabolic rate --->  the rate at which chemical reactions occur in our body; the rate at which our bodies break things down to produce energy, and build new tissue (metabolism).

To ensure that such medical condition is correctly detected, one's must undergo a detailed physical & blood examinations.

What is Pterygium and Pinguecula ?

[Extracted from the webpage of www.healthscout.com] A pterygium is a fleshy growth that invades the cornea (the clear front window of the eye). It is an abnormal process in which the conjunctiva (a membrane that covers the white of the eye) grows into the cornea. A pinguecula is a yellowish patch or bump on the white of the eye, most often on the side closest to the nose. It is not a tumor but an alteration of normal tissue resulting in a deposit of protein and fat. Unlike a pterygium, a pinguecula does not actually grow onto the cornea. A pinguecula may also be a response to chronic eye irritation or sunlight. Although pterygium and pinguecula sound like mysterious, arcane diseases, they are actually quite common, usually benign eye conditions. These lesions appear as a whitish-yellowish bump or fleshy "growth" on the exposed conjunctiva. If the bump appears only on the white part of the eye, it is called a pinguecula. If it appears to "grow" onto t

What is Angioplasty and Stenting ?

[Extracted from www.vascular.co.nz] An angioplasty is a procedure where a balloon is passed into your artery on the end of a tube (catheter) and is inflated (blown up) to treat a narrowed or blocked artery. The initiator of this technique was Charles Dotter , a radiologist in Oregon who started this work in 1964. The angioplasty technique means that surgery may be avoided in many cases. There are two techniques for performing angioplasty - transluminal and subintimal. In the transluminal technique the balloon is placed in the centre of the artery (in the lumen) where blood would normally flow. In subintimal angioplasty ( Bolia, 1989) the balloon is intentionally placed within the layers of the arterial wall. As far as the patient is concerned, angioplasty is very similar to an angiogram except that a slightly bigger catheter is used and therefore the risks of bleeding are slightly greater. For

What is Down Syndrome and its Causes ?

[Extracted from the webpage of  "Downsyndrome.about.com"] Down syndrome is caused by an extra number 21 chromosome. But what does this really mean ? To really understand what causes Down syndrome, you need to have a thorough understanding of what chromosomes are, and what they do. Genetic Information The easiest way to think of chromosomes is as packages of genetic information. The human body is made up of all different types of cells and inside each of these cells are our genes. Genes are the units of inheritance that are passed from one generation to another. They are located in every cell of our bodies and they provide the instructions for every structure and function of our body. Humans have about 25,000 different genes. Rather than having all 25,000 bouncing around inside cells individually, our genes are located or packaged on chromosomes rather like pearls on a necklace. Genes Genes are made of DNA which is a molecule made up of four different chemicals cal
