yes

5

What can cause chronic gastritis?

A

ABC and other.

Autoimmune, bacterial, Chemical and other.

6
Q

What can autoimmune problems (chronic gastritis) lead?

A

Pernicious anameia

7
Q

What causes bacterial infection in stomach?

A

Helicobacter pylori infection

8
Q

Notes on helicobacter pylori infection

A

Gram-neg bacteriain stomach, particularly antrum, infects over half the worlds population. Faecal-oral route. Untreated -> infection persists throughout life.

9
Q

H.pylori is linked to what development?

A

Duodenal ulcers and stomach ulcers

10
Q

What is the clinical presentation H.pylori.

A

80% asymptomatic. 5-15% peptic ulcer disease. 10% non-ulcer dyspepsia. 1-3% gastric adenocarcinoma.

11
Q

What are the effects of h.pylori infections predominantly in body of stomach.

A

Gastric cancer
Hypochlorhydria
Gastric atrophy
Intestinal metaplasia

12
Q

What are the effects of h.pylori infections predominantly in antrum.

A

Duodenal ulcers

Hyperchlorhydria

13
Q

What chemicals can cause chronic gastritis?

A

Alcohol, tobacco and caffeine

14
Q

What else (apart from ABC) can cause chronic gastritis?

A

Psychological stress

15
Q

Where does peptic ulcer disease usually occur?

A

D1 or antrum (4:1)

16
Q

What can cause peptic ulcer disease?

A

H. pylori (80-100% DU and 65% gastric). NSAIDs

17
Q

When are peptic ulcers worse?

A

at night and after meals

18
Q

What are the symptoms of peptic ulcer disease?

A

Pain (gnawing, burning and aching)

19
Q

What are complications of peptic ulcer disease?

A

Bleeding -> iron deficiency anaemia. Massive haematemesis. Performation -> peritonitis. Long term cancer at edge of ulcer

20
Q

What is Barrett’s Oesophagus?

A

When lining of oesophagus changes from stratified squamous epithelium to columnar epithelium with goblet cells

21

A

low in GIT

22

Who can suffer from oesophagus squamous cell carcinoma?

A

Adults over 45. M:F 4:1

25
Q

What are the survival rates for oesophagus squamous cell carcinoma?

A

5 year survival of 9%

26
Q

What are the risk factors for Oesophagus sqaumous cell carcinoma?

A

Alcohol, tobacco, caustic injury, achalasia

27
Q

Define achalasia?

A

when the lower part of the oesophagus fails to relax, preventing food passing to stomach
