Marshall and Warren discovered that the organism was there in almost every patient with gastric ulcer and inflammation. Based on the results of their findings, they suggested that Helicobacter pylori are involved in the aetiology of these diseases. In fact, Helicobacter pylori cause over 90% of duodenal ulcers and about 80% of gastric ulcers. After this discovery, research has been deep.
This bacterium can be diagnosed by identification of the organism in biopsies, by antibody tests or by non-invasive breath test which recognizes bacterial production of an enzyme in the stomach. The use of antibiotics to eliminate Helicobacter pylori may lead to severe problems since bacteria and chronic inflammation of the stomach remains. Marshall, Warren and other researchers showed that patients could be cured from peptic ulcer by eradication of the bacteria from the stomach. Due to Marshall and Warren's discovery, peptic ulcer is no longer a chronic disabling disease but can be cured by a short regimen of antibiotics and acid secretion inhibitors.
Stomach Ulcer Bacteria Survival in the Stomach:
Helicobacter pylori are the cause of many stomach ulcers and stomach cancer. More than half the population carries Helicobacter pylori without realizing it. Despite the strong reaction of the body, the bacterium usually activates the body's immune defenses leading to unending inflammation in the mucous membrane. When this bacterium infects the body, white blood cells try to amplify their manufacture of bactericidal substances known as free radicals (Claessen par, 4). The bacterium in return produces antioxidants...
Ulcer Many people say that an ulcer is caused by stress whereas scientific journals states that it is caused by bacteria. Actually, ulcer has traditionally been thought as a condition brought by stress as well as the consumption of coffee and spicy foods. Generally, an ulcer was believed to be a by-product of lifestyle factors like diet and stress. In the past few years, it has emerged that an ulcer is
Pressure Ulcers in the Elderly During Hospital Stays Pressure ulcers are potentially fatal skin lesions that develop especially in frail, elderly patients on bony or cartilaginous areas such as the sacrum, elbows, and ankles. Within acute care in the United States, the incidence of pressure ulcers lies between 0.4% and 38%. The incidence within long-term and home care is significantly lower while intensive care units report that 8% to 40% of
Peptic Ulcer Disease: Pathophysiology A peptic ulcer can be defined as "a focal mucosal defect with inflammatory cell infiltration and coagulation necrosis extending through the muscularis mucosae" (Halter, 1995, p. 2). Contrary to erosion, a peptic ulcer extends beyond the epithelial structures into that intestinal tract section that happens to be in constant contact with pepsin and acid-containing gastric juice (Halter, 1995). Peptic ulcers cause an imbalance between the gastro duodenal
Pressure Ulcers/Case Study Bedsores are also known as pressure ulcers. They are lesions that are primarily caused when soft tissues are pressed against bone for a long period of time, restricting blood flow to the area. These often occur when a patient is immobile or reclining in a recovery bed for a long period of time. They are common on the hips, elbows, knees, ankles and even the back of the
Preventing Pressure Ulcers in Postoperative Patients this is a nursing research evidence-based practice project paper. THIS IS A NURSING PROJECT. SINGLE SPACE. 6 PAGES FOR THE PROJECT, 2 PAGES FOR THE LISTED INFO Directions: 1. You developed EVIDENCE-BASED NURSING PRACICE PROJECT (EBP). What are the best practices to prevent pressure ulcers in postoperative patients? This project aims at implementing evidence-based prevention strategies for pressure ulcers in postoperative patients. There are many risk factors associated
Care for Diabetic Foot Ulcers in Long-Term Care Residents Diabetic foot ulcers are chronic wounds that negatively affect the morbidity, mortality and quality of life of diabetes patients. Diabetic patients who develop foot ulcers are at greater risk of heart attack, fatal stroke, and premature death. Unlike other types of chronic wounds, diabetic foot ulcers are more complicated and present unique treatment challenges especially when coupled with diminished tissue perfusion,
