Q

If a person tells you they have had a red/white lump in their mouth for a while, what would you ask them? What time frame would be suspicious for you? What disease may you consider?

A

I’d ask them how low long they’ve had it. If it is longer than 3 weeks, I’d consider oral/ oropharyngeal cancer as a possible prognosis.

Q

What GI problem is characterized by a longitudinal tear in the mucosal layer of the esophagus due to forceful, repeated vomiting or coughing

A

Mallory Weiss tear

26
Q

What vessel can be of concern when talking about collateral drainage into the esophageal vessels? Why might this be concerning?

A

The portal vein can drain too much in esophageal vessels in portal hypertension which may lead to rupture and can be fatal

27
Q

A person is experiencing abnormal function of the lower esophageal sphincter and/or a hiatal hernia, what disease may this cause?

A

Gastroesophageal Reflux Disease (GERD)

28
Q

What is Gastroesophageal Reflux Disease (GERD)?

A

Reflux of gastric contents into the esophagus

29
Q

What effects can result from Gastroesophageal Reflux Disease (GERD)?

A

Inflammation (Barrett’s esophagus)
Ulcerations
Carcinogenesis

30
Q

What cell initially begins the inflammation reaction in GERD?

A

intramucosal eosinophils

31
Q

What does the normal squamous epithelium change into when someone is experiencing Barrett’s syndrome?

A

The normal squamous epitheliumlining of the esophagus is replaced by metaplastic columnar and goblet cells.

32
Q

The presence of what cell can diagnose someone with Barrett’s esophagus?

A

Goblet cells

33
Q

What can Barrett’s esophagus have a strong association with?

A

esophageal adenocarcinoma

34
Q

60%

36
Q

What are symptoms of a hiatal hernia?

heartburn
esophagitis

37
Q

What can occur with gastroesophageal reflux in infants?

A

hiatal hernia

38
Q

What passes through the esophageal hiatus?

A

39
Q

What layer of the stomach is associated with gastritis?

A

Mucosa layer

40
Q

When someone is experiencing pain with gastritis, where may this pain occur? What may it be mistaken with?

A

Pain usually occurs high in the abdomen, just below the end of the sternum.

42
Q

A person says they’ve done cocaine for a long time, what GI problem might they develop? Why?

A

Gastritis.
Chronic use constricts blood vessels in stomach and increases the risk of injury by inducing chronic hypoxia

Q

What do 80% of peptic ulcers occur in?

A

Duodenum

49
Q

What bacteria causes 90% of peptic ulcers and chronic trophic gastritis?

A
