The HACEK organisms are a group of fastidious Gram-negative bacteria that are an unusual cause of infective endocarditis, which is an inflammation of the heart due to bacterial infection. [1] HACEK is an abbreviation of the initials of the genera of this group of bacteria: Haemophilus , Aggregatibacter (previously Actinobacillus ...
The bacteria goes into the stomach lining and changes it, causing inflammation, Woo says. A very high salt diet is another risk factor, as is eating lots of charred, smoked and preserved foods ...
CagA (cytotoxin-associated antigen A) is a major virulence factor for H. pylori, an oncoprotein that is encoded by the cagA gene. Bacterial strains with the cagA gene are associated with the ability to cause ulcers, MALT lymphomas, and gastric cancer. [108] [109] The cagA gene codes for a relatively long (1186-amino acid) protein.
Gibelli claims to be unable to reproduce Turck's study where he artificially created ulcers by feeding dogs bacteria. [1] Streptococci 1913 Rosenow suggests that streptococci produce ulcers. [8] 1915 Antacids are first recommended for the treatment of PUD. [3] Bacteria are associated with PUD, but it is assumed that the bacteria reside in the ...
Acid peptic diseases, such as peptic ulcers, Zollinger-Ellison syndrome, and gastroesophageal reflux disease, are caused by distinct but overlapping pathogenic mechanisms involving acid effects on mucosal defense. Acid reflux damages the esophageal mucosa and may also cause laryngeal tissue injury, leading to the development of pulmonary ...
Gastroesophageal reflux disease (GERD) or gastro-oesophageal reflux disease (GORD) is a chronic upper gastrointestinal disease in which stomach content persistently and regularly flows up into the esophagus, resulting in symptoms and/or complications.
This is complemented by gastro-coronary reflexes [12] whereby the coronary arteries constrict with "functional cardiovascular symptoms" similar to chest-pain on the left side and radiation to the left shoulder, dyspnea, sweating, up to angina pectoris-like attacks with extrasystoles, drop of blood pressure, and tachycardia (high heart rate) or ...
Heartburn, also known as pyrosis, cardialgia or acid indigestion, [2] is a burning sensation in the central chest or upper central abdomen. [3] [4] [5] Heartburn is usually due to regurgitation of gastric acid (gastric reflux) into the esophagus. It is the major symptom of gastroesophageal reflux disease (GERD). [6]
