ABSTRACT
Ludwig’s angina is an infection of the submandibular space often secondary to a dental infection. Swelling can cause the tongue to be displaced backwards, resulting in airway obstruction.
18a. T 18b. F 18c. T 18d. F Duodenal ulceration is two to three times more common than gastric ulcer. Curling’s ulcer occurs after trauma/stress. Zollinger-Ellison syndrome is a gastrin-secreting pancreatic adenoma, leading to excess acid secretion. Helicobacter pylori infection is associated with 95% of duodenal and 80% of gastric ulcers. H2-receptor histamine antagonists such as ranitidine reduce acid secretion.
