Q

4 ways H pylori affects acid secretion in the stomach

A

1- causes G cells to release more gastrin
2- triggers release of histamine which causes more acid secretion
3- increases parietal cell mass- more gastric acid production (HCl)
4- decreases somatostatin release from D cells- more acid secretion

Q

how does h pylori cause peptic ulcers

A

h pylori secrets urease which splits urea in stomach into CO2+ and ammonia.
Ammonia and H+ = ammonium
Ammonium, proteases, phospholipases and vacuolating cytotoxin A damage gastric epithelium. Causes inflammatory response, reducing mucosal defence and causing mucosal damage

Q

how does recurrent NSAID use cause peptic ulcers

A

mucus secretion is stimulated by prostaglandins, and COX-1 is needed for prostaglandin synthesis. NSAIDs inhibit COX-1 -> less mucus secretion -> reduced mucosal defence

Q

first line investigation for bowel obstruction

A

x ray abdomen

19
Q

duodenal ulcer symptoms and how is it different from peptic ulcers?

A

duodenal ulcers cause abdominal pain several hours after eating due to the presence of acid from the stomach in the duodenum. pain caused by gastric ulcers is relieved by eating

20
Q

inflammation- differences between ulcerative colitis and crohn’s

A

Ulcerative colitis; continuous inflammation from the rectum to the ileocecal valve, does not extent proximal to the ileocecal valve. Smoking is protective

Crohn’s: anywhere in the gastrointestinal tract, skip lesions, trasmural inflammation cobblestone appearance. Smoking is a risk factor

21
Q

gold standard investigation for bowel cancer

A

colonoscopy

22
Q

which of proximal/distal colon cancer is

  • more common
  • more dangerous
A
  • distal more common

- proximal more dangerous

23
Q

is pANCA raised in UC or Crohn’s?

A

pANCA (anti-neutrophilic cytoplasmic antibody) is always negative in Crohn’s but may be positive in Ulcerative colitis

24
Q

What might investigation results show in crohn’s disease?

A
  • Raised ESR and CRP (IBD)

- Iron and folate deficiency anaemia- commonly due to malabsorption

25
Q

4 causes of AKI

A

1 acute tubular necrosis- most common cause, tubular epithelial cells die impairing kidney ability to filter waste products

2- nephrotoxins- cause intrinsci/renal AKI, kidneys are directly damaged impairing their ability to function

3- prostate hyperplasia- causes post-renal AKI; urinary tract is obstructed, increasing intra-tubular pressure and decreasing GFR and thus increasing urea and creatinine remaining in the blood

4- sepsis- prerenal cause of AKI; bp falls leading to renal hypoperfusion and decreased GFR which causes a rise in serum urea and creatinine

26
Q

what are the GFRs for the different stages of CKD?

A

stage 1- >90ml/min with evidence of renal damage

stage 2- 60-89 ml/min with evidence of renal damage

stage 3a- 45-59 ml/min with/without renal damage

stage 3b- 30-44 ml/min with/without renal damage

stage 4- 15-29 ml/min with/without renal damage

stage 5- <15ml/min, established renal failure

27
Q

5 organisms which cause pyelonephritis and the most common one

A

coagulase negative staph, enterococcus, e.coli (most common), Klebsiella, proteus

28
Q

best investigation in the management of pyelonephritis

A

midstream urine microscopy, culture and sensitivity

29
Q

characteristic symptoms of chronic prostatitis

A

pelvic or perineal pain lasting longer than 3 months is the key symptom. Also trauma causing nerve damage in the lower urinary tract is a risk factor for chronic prostatitis.

30
Q

which UTI drug is teratogenic and which is first line in pregnancy?

A

trimethoprim can be teratogenic, nitrofurantoin is first line in pregnant women

31
Q

what is retiers syndrome? what is the reiters triad?

A

reactive arthritis. triad is conjunctivitis, urethritis and arthritis

32
Q

4 possible complications of polycystic kidney disease

A

1- PKD causes hypertension, which can result in cardiovascular disease.

2- Kidney stones may form in those with PKD as urine travels more slowly in the kidneys of these patients allowing more time for stones to develop.

3- Polycystic liver disease can occur as people with PKD develop cysts in other organs.

4- PKD is associated with Berry’s aneurysms and if they rupture results in a subarachnoid haemorrhage.

33
Q

What are the stages of the Ann Arbor staging system?

A

I Confined to single lymph node region.

II Involvement of two or more nodal areas on the same side of the diaphragm.

III Involvement of nodes on both sides of the diaphragm.

IV Spread beyond the lymph nodes, e.g. liver or bone marrow.

Each stage is either ‘a’—no systemic symptoms other than pruritus; or ‘b’—presence of b symptoms: loss of appetite, weight loss and drenching night sweats.

34
Q

treatment for DVT

A

acute management with a LMWH (e.g. deltaparin) or Fondaparinux followed by maintenance treatment for 6 months with an oral anticoagulant (e.g. warfarin)

35
Q

describe the mechanism of action and uses for

  • rituximab
  • trastuzumab
  • adalimumab
A
  • rituximab is a monoclonal antibody used to treat non-hodgkin lymphoma, chronic lymphocytic leukemia etc. Rituximab stcks to CD20 proteins on the surface of B Cells and immune cells then pick them out and kill them
  • Adalimumab is a biological disease modifier used to treat rheumatoid arthritis and other chronic conditions mediated by tnf-alpha, inhibiting its actions. also used in the treatment of psoriatic arthritis, ankylosing spondylitis
  • Trastuzumab is a targeted cancer drug which treatds cancers with a large amount of the protein human epidermal growth factor receptor 2 (HER2) e.g. early breast cancer, advanced breast cancer and stomach cancer.
36
Q

Malaria treatment

  • uncomplicated
  • severe/complicated
  • second line severe/complicated
A
  • uncomplicated = chloroquine
  • severe/complicated= IV artesunate
  • 2nd line severe/complicated= IV quinine and doxycycline
37
Q
  • transferrin- job

- ferritin- jon

A
  • ferritin= mainly in body cells, with little circulating in blood. Protein that stores iron and releases it when your body needs it
  • transferrin is a protein which combines with ferritin to transport it to where new blood cells are made
38
Q

4 signs of liver failure

A
  • asterixis (liver flap)
  • dupuytren’s contractures (progressive shortening and thickening of the palmar fascia causing finger contractures)
  • leukonychia (white nails)
  • spider naevi (small swollen blood vessels beneath the skin)
39
Q

GET SMASHED- pancreatitis causes?

A

gall stones, ethanol excess, trauma, steroids, mumps, autoimmunity, scorpion venom, hyperlipidemia (or hypercalcaemia/hypothermia), ERCP and drugs

40
Q

4 common signs of an upper GI bleed

A

coffee ground vomit (haematemesis)
hypotension
Malaena (black stools)
tachycardia

41
Q

first line treatment for alcohol withdrawal

A

Chlordiazepoxide

42
Q

Wernickes encephalopathy is caused by a deficiency in vitamin

A

B1 (thiamine)

43
Q

Folate and vitamin D deficiencies are common causes of
