How would this infection appear macroscopically and what kind of population would you expect to receive this sample from.

Page 3: Robbins and Davidson’s

• Name one other organism that commonly causes oesophagitis.

Page 4: Robbins and Davidson’s

• CMV, candidiasis, aspergillus, macronycosis

Page 5: Robbins and Davidson’s

• Name four other causes of oesophagitis.

Page 6: Robbins and Davidson’s

• Pill induced.• Irritants – alcohol, acids, alkalis, hot fluids,

smoking• Skin diseases – bullous pemphigoid etc• Reflux• Eosinophilic• Rarely – Crohn’s

Page 7: Robbins and Davidson’s

• How would you differentiate between a mallory-weiss tear and rupture of oesophageal varices?

Page 8: Robbins and Davidson’s

The following condition predisposes to what?

Page 9: Robbins and Davidson’s

• All of the following characteristics are associated with Barrett’s oesophagus except:

• A metaplastic goblet cells• B metaplastic parietal cells• C intranuclear inclusion bodies• D epitheliel dysplasia• E adenocarcinoma of the oesophagus

Page 10: Robbins and Davidson’s

• What other complications can be caused by GORD?

Page 11: Robbins and Davidson’s

• Oesophagitis• Anemia• Benign oesophageal stricture• Gastric volvulus

Page 12: Robbins and Davidson’s

• What conditions predispose to the development of GORD?

Page 13: Robbins and Davidson’s

• Abnormalities of the LES• Hiatus hernia• Delayed oseophageal clearance• Defective gastric empyting• Dietary and environmental factors• etc….

Page 14: Robbins and Davidson’s

• Name three different approaches to the management of GORD.

Page 15: Robbins and Davidson’s

• Lifestyle advice• PPI, H2 receptor antagonists• Laparoscopic anti-reflux surgery

Page 16: Robbins and Davidson’s

• Your next patient is a 53 yo male. Mr William T admits to going to the toilet often to pass urine during the night, rising 3 to 5 times. He states that his flow is reduced at night and that he dribbles a little at the end of micturition. He states that he is fine during the day.

• What are the three types of diverticulae that form in the oesophagus?

Page 17: Robbins and Davidson’s

• Zenker• Traction• Epiphrenic

Page 18: Robbins and Davidson’s

• Diverticulae are often secondary to obstruction. One such oesophageal obstruction is achalasia. What is achalasia?

• List at least one primary and one secondary cause of achalasia.

Page 19: Robbins and Davidson’s

• Achalasia – incomplete LES relaxation, increased LES tone, aperistalsis of the oesophagus

• Primary – idiopathic• Secondary – Chaga’s, diabetic autonomic

neuropathy, malignancy, amyloidosis

Page 20: Robbins and Davidson’s

• You perform an endoscopy on a patient you suspect of having chronic gastritis. You notice that there is marked inflammation in the fundus and the body, but the antrum appears to be spared. In the areas of inflammation there are no rugae and there appears to be small polyps or nodules. What form of gastritis seems most likely?

• A H. pylori chronic gastritis• B Autoimmune gastritis• C Eosinophilic gastritis• D Zolligner-Ellison syndrome

Page 21: Robbins and Davidson’s

• For each of the characteristics listed below, choose whether it describes acute gastritis, chronic gastritis or both.

• Associated with alcohol consumption.• Associated with smoking.• Causally related to autoantibodes against gastric mucosal

cells.• Associated with the use of aspirin.• Productive of GIT bleeding.• Associated with gastric peptic ulcers.• Associated with Hpylori infection.

• Associated with alcohol consumption. A• Associated with smoking. A • Causally related to autoantibodes against gastric mucosal

cells. C • Associated with the use of aspirin. A• Productive of GIT bleeding. A• Associated with gastric peptic ulcers. C• Associated with Hpylori infection. C

Give five symptoms that are commonly associated with the above slide taken from a biopsy of the stomach.

Page 24: Robbins and Davidson’s

Dyspepsia, dysphagia, nausea.Weight loss, anorexia, anemia, haemorraghe.

This sort of diffuse infiltrative growth leads to a macroscopic appearance termed…?

Page 25: Robbins and Davidson’s

• Linitis plastica

Page 26: Robbins and Davidson’s

• Which type of hiatus hernia is not likely to cause regurgitation?

• What symptoms may these type of hernia cause?

• What is the difference between a direct and indirect inguinal hernia?

• Through palpation how can one differentiate between a femoral and an inguinal hernia?
