Pneumoperitoneum is pneumatosis (abnormal presence of air or other gas) in the peritoneal cavity, a potential space within the abdominal cavity.The most common cause is a perforated abdominal organ, generally from a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.
Peptic ulcer disease is when the inner part of the stomach's gastric mucosa (lining of the stomach), the first part of the small intestine, or sometimes the lower esophagus, gets damaged. An ulcer in the stomach is called a gastric ulcer , while one in the first part of the intestines is a duodenal ulcer . [ 1 ]
The pathophysiology of acute respiratory distress syndrome involves fluid accumulation in the lungs not explained by heart failure (noncardiogenic pulmonary edema). It is typically provoked by an acute injury to the lungs that results in flooding of the lungs' microscopic air sacs responsible for the exchange of gases such as oxygen and carbon dioxide with capillaries in the lungs.

Turck feeds dogs Bacillus coli and produces ulcers. [7] 1907 Berkley Moynihan suggests that acid is a cause of ulcers. [1] 1910 Schwartz publishes the excess acid theory of the ulcer, coining the famous phrase "no acid, no ulcer." [2] Gibelli claims to be unable to reproduce Turck's study where he artificially created ulcers by feeding dogs ...
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 1 ] [ 2 ] [ 3 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
Lobar pneumonia is a form of pneumonia characterized by inflammatory exudate within the intra-alveolar space resulting in consolidation that affects a large and continuous area of the lobe of a lung. [1] [2] It is one of three anatomic classifications of pneumonia (the other being bronchopneumonia and atypical pneumonia).
Zollinger-Ellison syndrome (ZES) is caused by a gastrinoma, which is a gastrin-producing tumor that causes gastric acid hypersecretion. [11] The main clinical manifestations of ZES are peptic ulcers and diarrhea. [12] The initial diagnostic test for ZES is a fasting serum gastrin level when antisecretory medications are stopped. If the gastrin ...
The genus Klebsiella was named after the German microbiologist Edwin Klebs (1834–1913). [citation needed] It is also known as Friedlander's bacillum in honor of Carl Friedländer, a German pathologist, who proposed that this bacterium was the etiological factor for the pneumonia seen especially in immunocompromised individuals such as people with chronic diseases or alcoholics.
