| spiced food. Pickles hot liquids and fried food |

Term
|
Definition
|
|
Term
| Aspirin and nonsteroid anti-inflammatory drugs may promote ulcer formation by |

inhibiting synthesis of prostaglandins. ( Prostaglandins contribute to the integrity of the gastric mucosal barrier) |

Definition
|
|
Term
common factors responsible for inducing peptic ulcers |
|
Definition
Abnormal vagal impulses Infection Hyperacidity |
|
|
Term
|
Definition
| Persons with prolonged hyperacidity especially at night when the stomach has emptied its contents into the duodenum are prone to develop ulcers, which are duodenal rather than gastric. |
|
|
Term
|
Definition
Hematogenous infection with organisms of low-grade virulence may cause inflammatory foci in the stomach wall leading to necrosis with subsequent digestion and ulcer formation. 100% have H. pylori infections |
|
|
Term
| Why is the duodenum more at risk for developing ulcers compared to the stomach |
|
Definition
| Duodenum does not have the thick mucus of the stomach |
|
|
Term
| Neurogenic theory of peptic ulcers |
|
Definition
| Abnormal vagal impulses from the hypothalamic region. Peptic ulcers are more common in patients with mental worry and strain. |
|
|
Term
| The role of the neurogenic theory in the production of peptic ulcer: |
|
Definition
a) vascular spasm and ischemia, which cause the initial area of necrosis b) hypersecretion of the gastric juice c) hypermotility, leads to removal of the protective layer of mucous, exposing the mucosa to the destructive action of the gastric secretion |
|
|
Term
| Complications of peptic ulcers |
|
Definition
| Hemorrhage, Perforation, Cicatricial contraction |
|
|
Term
|
Definition
due to erosion of thin vessels leading to hematemesis. If hemorrhage is slight, occult blood appears in stools. |
|
|
Term
|
Definition
Is more common the anterior wall of the stomach or duodenum. Perforation leads to either a sub diaphragmatic abscess or to generalized peritonitis |
|
|
Term
|
Definition
Due to gradual contraction of the fibrous base of the ulcer producing one of the following deformities: a) Pyloric stenosis and great dilatation of the stomach. b) Hour-glass stomach, if the ulcer is on the lesser curvature and the sear tissue pulls upon the greater curvature. |

Term
| Polypoid or fungating carcinoma: |

Definition
| a large soft fungating mass projects into the lumen of the stomach, associated with ulceration, hemorrhage and infection. |
|
|
Term
| Effects of morbid anatomy of the stomach |
|
Definition
1- Loss of appetite: early, due to infiltration of the muscular wall of the stomach, interferes with the gastric tone ( reduces the sense of appetite) 2-Bleeding (hematemesis) 3- Pyloric obstruction with vomiting 4- Occult blood in stools 5-Cancer cachexia: (loss of appetite, weight and marked anemia) 6-Gastric juice findings: a. hypochlorhydria or achlorhydria ( due to mucosal destruction) b. pyloric obstruction allows fermentation of the retained food and forms lactic acid. c) Cancer cells and blood cells can be detected. |
