What is hepatitis? Hepatitis is an inflammation of the liver. This inflammation can be acute (short term illness) or chronic (more than half a year of illness). What causes hepatitis? Hepatitis may occur as a result of viral infections, alcohol and other intoxicants or drugs. Most of the time there is talk of hepatitis, we refer to hepatitis caused by viruses, so we will focus only on viral hepatitis. Acute... 

This entity was first described by Hutchinson in 1890. Horton was in 1930 when histology revealed granulomatous arthritis of temporal vessels. And 20 years later postulated the relationship between temporal arthritis and polymyalgia rheumatica (in fact many authors consider to be two different phases of the same disease) We define temporal arthritis, also called giant cell arthritis(GCA) or Horton... 

In previous work, the researcher Mary JC Hendrix and colleagues discovered that aggressive melanoma cells (as opposed to normal cells and less aggressive melanoma) contain specific proteins similar to those found in embryonic cells. This work allows a first molecular classification of malignant melanoma and may help explain how behaving like unspecialized stem cells, melanoma cells migrate, invade... 

Appendicitis and Meckel’s diverticulum connection Appendicitis Appendicitis, most common in teenagers and young adults, is inflammation of the appendix together with obstruction of its intestinal opening. Symptoms include pain, fever and tenderness in the lower right quadrant of the abdomen, although tenderness at first can be located more centrally. Nausea and vomiting are typical, too, but not... 

Does sex good for arthritis Yes, it is. But researches have no sure answers as to why it should be so. They doubt that it may be because to the stimulation in the adrenal glands which follows sexual arousal. This adrenal glands produce cortisones, which reduces inflammation, therefore maybe bringing relief from arthritis pain. A trickier and more important question is “how to encourage those arthritis... 

What is asthma? Asthma is a chronic, noncontiguous condition that affects the respiratory tubes in the lungs, particularly the bronchioles, the fine subdivisions of the bronchial tubes. Essentially, asthma involves an over-reaction by the lining of the bronchioles to either a substance (possibly an allergen causing an allergic reaction) or to an excessively stimulating situation, involving stress...

There are, however, seven general warning signs: (1) unusual bleeding or discharge from any part of your body; (2) a lump or change in the appearance or feel of skin or underlying tissue anywhere in your body but especially in the breasts; (3) any sore that... 

Whether you’re a man or a woman, sexual activity brings with it a risk of infections passed from person to person. For one reason or another, the germs responsible for such diseases grow especially well in male and female sexual organs, most obviously the penis and vagina. From there infection may spread up the genital tract to the epididymis in the male and to the uterus in the female. But other... 

Heart blood vessels and veins arteries Although light in weight and compact in size, the heart is remarkably successful in performing its life-sustaining work: pumping blood that is rich in oxygen and nutrients to every cell in the body and carrying of waste products, such as carbon dioxide. The task is not easy, for there thousands of kilometers of blood vessels in the body, and the heart must beat... 

Doctors say it isn’t laughter that causes hiccups but more probably the feasting that goes with fun. Too much food and drink may irritate the diaphragm, a sheetlike muscle separating the chest and the abdomen. The victim loses control of the diaphragm, which contracts suddenly and causes a rapid closure of the vocal chords. The result is a loud and sometimes embarrassing hick. Many attacks of...
