Causes In 1982, two Australian scientists identified H. pylori as the main cause of stomach ulcers. They showed that inflammation of the stomach and stomach ulcers result from an infection of the stomach caused by H. pylori bacteria. This discovery was so important that the researchers were awarded the Nobel Prize in Medicine in 2005. The bacteria appear to trigger ulcers in the following way: H. pylori's corkscrew shape enables them to penetrate the mucus layer of the stomach or duodenum so that they can attach themselves to the lining. The surfaces of the cells lining the stomach contain a protein, called decay-accelerating factor, which acts as a receptor for the bacteria. H. pylori survive in the highly acidic environment by producing urease, an enzyme that generates ammonia to neutralize the acid. H. pylori stimulate the increased release of gastrin. Higher gastrin levels promote increased acid secretion. The increased acid damages the intestinal lining, leading to ulcers in certain ...

In fact, someone might be minding his/her own business enjoying a pain-free life when suddenly an innocent sneeze leads to months of debilitating lo...
About once or
twice a month, I see a young male in his late teens or early 20s who come to me
to evaluate a bump or lesion on his penis. Interestingly, many of these men
have sought evaluation before and STILL don't know what they have.
Here are the
most common causes of this symptom:
grouped lesions on the penis that are painful? Think about genital herpes as the cause. These lesions can also occur on the buttocks or anal area. The
initial outbreak may be associated with fever. Herpes is the most common STD in
and most genital lesions in men are herpes.
Have a bump
that looks like a wart or has a cauliflower appearance? You may have genital
warts. Warts are caused by certain strains of human papillomavirus --
different ones than those that cause cervical cancer in women. In most cases,
the warts do not cause symptoms, but occasionally they can burn, itch or be
tender. They can also produce a discharge. The lesions may be tan, pink or
