What is malaria?

The malaria , also called malaria , is the most important parasitic disease of humans. It is caused by several species of a genus of protozoan called Plasmodium that is transmitted from one human host to another through the bite of female mosquitoes of the genus Anopheles . Occur between 200 and 300 million cases each year worldwide and about one million deaths per year, 90% in sub-Saharan Africa and in children under five. Read the rest of this entry »

Health, men and women are different. Just as before the illness. These observations deserve to be known.

To each his own prescription
From a strictly organic, the woman is not equal to men . Weight, morphology, renal and hepatic metabolism, hormonal fluctuations … These factors may influence the action of a drug. Similarly, women are more prone to side effects than men . An extensive survey conducted in 2005 on the effects of aspirin has led to surprising conclusions: it does not have the same protective properties by gender but also by age in women. Before age 65, it reduces the risk of stroke (not humans), but would be of interest in the prevention of myocardial past 65 years. Read the rest of this entry »

Description:

In bladder cancer, cancer cells invade the bladder harmful and destroy normal cells   And the bladder can no longer function properly.

The bladder is a hollow organ that stores urine as it is filtered by the kidneys. Its flexible wall consisting of three layers of fabric, allows it to stretch and contract as needed. Most bladder cancers (90%) are implanted in the epithelial lining, the deepest layer of the wall.

The bladder cancer is the 6th most common cancer in Canada. Its incidence is two to three times higher in men than in women, and two times higher among Caucasians than among those original African. In North America, it ranks fourth in men and the ninth in women, in terms of frequency.

Thanks to earlier diagnosis and improved treatment, mortality rates for this disease have declined significantly over the past 25 years. Read the rest of this entry »

Description

Called sudden appendicitis inflammation or swelling of the appendix. The appendix is a tube-like structure that starts from where the large intestine (colon) begins. It is the size of a pencil and is normally about 7 cm (4 inches).

For many years, scientists were unsure of the function of the appendix in the body. We now know that it helps make immunoglobulins, substances that are part of the immune system. Immunoglobulins are made in many parts of the body. Thus, the removal of the appendix does not seem to result from immune system problems.

Today, appendicitis is rarely fatal, through the use of antibiotics and surgery safely. It affects 1 in 15 people and is more often men than women. It affects very few children often below 3 years and occurs most commonly between 10 and 30 years. Read the rest of this entry »

Description

Styes are usually temporary and mild bacterial infection affecting the edge of the eyelid or eye. Glands around the eyelid get clogged and swell until a sore like a small pimple or to a boil. A stye can also result from a blockage of the follicle of an eyelash. The sore causes pain in the eye and temporarily filled with pus. A second type of stye, worse, can develop deeper inside the eyelid and swell until medical intervention is necessary.

Styes are the most common type of infection of the eyelid. On average, each person develops one or two in his lifetime, although some people develop them repeatedly. They can be unpleasant and painful, but they are usually harmless.

Causes

There are actually two distinct types of stye. Both are usually caused by a bacterium known as staph. This bacterium, common on the skin, can multiply rapidly and cause infections. In case of ordinary stye, called an external hordeolum, the infection starts at the root of an eyelash (the follicle), unleashing a process that results in a swelling. This type of stye can also be caused by staphylococcal infection of the glands of Moll and Zeiss, close to the follicles. When the stye swells and begins to infect or clog other glands around the eyelid, it causes pain and discomfort. At this point, one can often see or feel a lump, a small pimple-like reddish abscess that begins to fill with pus. Styes often occur in people with weak immune resistance due to conditions such as diabetes, or a local predisposition such as acne. Read the rest of this entry »
