peptic ulcer - pathophysiology A selection of articles related to peptic ulcer - pathophysiology: In patients in whom peptic ulcer is suspected, esophagogastroduodenoscopy (EGD, a form of endoscopy) is indicated. By direct visual identification, the location and severity of an ulcer can be described. Moreover, if no ulcer is present, EGD can often provide an alternative diagnosis Classical causes of ulcers (tobacco smoking, blood groups, spices and a large array of strange things) are of relatively minor importance in the development of peptic ulcers. A major causative factor (90% of gastric and 75% of duodenal ulcers) is chronic inflammation due to Helicobacter pylori, a spirochaete that inhabits the antral mucosa and increases gastrin production. Gastrin, in turn, stimulates t .. See this and more articles and videos below.

* Encyclopedia II - Peptic ulcer - Diagnosis

In patients in whom peptic ulcer is suspected, esophagogastroduodenoscopy (EGD, a form of endoscopy) is indicated. By direct visual identification, the location and severity of an ulcer can be described. Moreover, if no ulcer is present, EGD can often provide an alternative diagnosis. The diagnosis of Helicobacter pylori can be by: Biopsy during EGD; Breath testing (does not require EGD); Direct culture from an EGD biopsy specimen; Direct detection of urease activity in a biopsy sp ...

* Encyclopedia - Campylobacteriosis

Campylobacteriosis is among the most common bacterial infections of humans. It produces an inflammatory, sometimes bloody, diarrhea or dysentery syndrome. It is responsible for proctocolitis in participants of anoreceptive intercourse, bacteremia in AIDS patients and other immunocompromised patients, and travelers' diarrhea. Helicobacter pylori is closely related to Campylobacter and causes peptic ulcer disease. Campylobacteriosis - Epidemiology. An estimated 2 million cases of Campylobacte ... Including:

* Encyclopedia II - Hydrochloric acid - Hydrochloric acid and living organisms Hydrochloric acid - Physiology. Hydrochloric acid constitutes the majority of gastric acid, the human digestive fluid. In a complex process and at a large energetic burden, it is secreted by parietal cells (also known as oxyntic cells). These cells contain an extensive secretory network (called canaliculi) from which the HCl is secreted into the lumen of the stomach. They are part of the epithelial fundic glands (also known as oxyntic glands) in the stomach. ...

* Encyclopedia II - Peptic ulcer - Signs and symptoms

Symptoms of a peptic ulcer can be: Abdominal pain; Hematemesis (vomiting blood); Melena (tarry feces due to oxidised iron from hemoglobin); Weight loss; Rarely, an ulcer can lead to a gastric or duodenal perforation. This is extremely painful and requires immediate surgery. A history of heartburn, gastroesophageal reflux disease (GERD) and use of certain forms of medication can raise the suspicion for peptic ulcer. Medicines associated with peptic ulcer are NSAID (non-steroid anti-inflammatory drugs) that inhibit cyclooxygenas ...

* Encyclopedia II - Peptic ulcer - Epidemiology

In Western countries the prevalence of Helicobacter pylori infections roughly matches age (i.e., 20% at age 20, 30% at age 30, 80% at age 80 etc). Prevalence is higher in third world countries. Transmission is by food and human contact, sharing food utensils etc. A minority of cases of Helicobacter infection will eventually lead to an ulcer and a larger proportion of people will get non-spec ...

* Encyclopedia II - Peptic ulcer - Treatment

Younger patients with ulcer-like symptoms are often treated with antacids or H2 antagonists before EGD is undertaken. Bismuth compounds may actually reduce or even clear organisms. When H. pylori infection is present, the most effective treatments are combinations of 2 antibiotics (e.g. Erythromycin, Ampicillin, Amoxicillin, Tetracycline, Metronidazole) and 1 proton pump inhibitor (PPI). An effective combination would be Amoxicillin + Metronidazole + Pantoprazole (a PPI). In the absence of H. pylori, ...
