Q

Diverticulitis management

A
  • Mild presentation: oral antibiotics, analgesia, low residue or liquid diet
  • Severe presentation:
    • Supportive management:NBM, IV fluids and analgesia
    • IV antibiotics:co-amoxiclav is typical but depends on local guidelines
    • Acute PR bleeding: transfuse blood products and arrange angiographic embolisation (blocks blood vessels) if available, otherwise, surgery is required
    • Surgery: if bleeding is not controlled or perforation is present, emergency surgical resection is required e.g. Hartmann’s procedure (removing the affected section of the bowel and creating an alternative path for faeces to be passed).
  • Diverticular abscess: radiological drainage or surgery
  • Recurrent diverticulitis: elective colonic resection

Q

Tubulo-interstitial causes of AKI

A

usually due to acute tubular necrosis (ATN). Other tubulointerstitial causes include acute interstitial nephritis that can occur secondary to medications (e.g. NSAIDs, PPI’s, penicillins) and infections. This typically leads to damage to the renal parenchyma that can lead to scarring and fibrosis in the long-term.

Q

how do you protect the myocardium with hyperkalaemia

A
  • Protection of the myocardium:10ml of 10% calcium gluconate.
  • Reduce extracellular potassium: aim is to drive potassium into the intracellular compartment. Insulin and beta agonists (e.g. 2.5mg nebulised salbutamol) are given.
  • Additional: stop or adjust potassium-sparing or potassium-containing medications. Resins can reduce potassium absorption but these takehours/days to have effect.

Q

22
Q

prophylaxis for dvt after hip replacement

A

Patients undergoing an elective hip replacement should be given
thromboprophylaxis with either a low molecular weight heparin administered for 10 days

an anticoagulant

24
Q

what is the target for rituximab

25
First line for uncomplicated malaria
Artemether with lumefantrine (Riamet)
26
First line for complicated malaria
1. Artesunate- this is the most effective treatment but is not licensed. 2. Quinine dihydrochloride
27
What is the name for a malignant tumour of smooth muscle
Leiomyosarcoma
28
What is the medication for paracetamol overdose
N-acetyl cystine
29
What enzyme degrades trypsin
chymotrypsin C
30
What are the causes of acute pancreatitis
I GET SMASHED, pregnancy, neoplasia
31
Genetic link to pancreatitis
PRSS1
32
Signs of Pancreatitis
Should be suspected in any person with: - Acute upper or generalised abdominal pain, particularly if they have a history or clinical features of gallstones or alcohol misuse - Abdominal tenderness and guarding - Abdominal distension - Jaundice - Cullen's sign - periumbilical bleeding, secondary to intraperitoneal haemorrhage - Grey Turner's syndrome - flank bleeding secondary to retroperitoneal haemorrhage - Fox’s sign: bleeding over the inguinal ligament secondary to retroperitoneal haemorrhage
33
symptom of pancreatitis
Poor urinary output: due to insensible fluid losses, third-spacing (movement of fluid from intravascular to interstitial spaces) - Nausea, vomiting and anorexia - Severe upper abdominal pain - Steatorrhoea
34
the scoring of pancreatitis
Modified glasgow scoring
35
Primary investigation of pancreatitis
- Serum amylase: amylase rises faster than lipase but also levels fall faster within 24-48hrs; less specific than lipase; is not of prognostic value. Serum amylase may be raised in other conditions such as renal failure, so is non-specific - Serum lipase: more specific for acute pancreatitis; levels rise slower than amylase but have a longer half-life. Amylase is tested more frequently in the UK
36
Acute pancreatitis treatment
IV Fluid resuscitation... - ERCP - Cholecystectomy - Alcohol cessation and withdrawal management
37
PBC key presentation
The classic presentation of PBC is with significant itching in a middle-aged female. (I think its just jaundice really from charcot's triad)
38
Signs of PBC
- Skin hyperpigmentation: due to increased melanin - Clubbing - Mild hepatosplenomegaly - Xanthelasma and xanthomata (late sign) - due to leakage of cholesterol - Scleral icterus (late sign)
39
Symptoms of PBC
- Pruritis (itchy skin) - leakage of bile salts - Fatigue and weight loss - Dry eyes and dry mouth - Sjögren's syndrome - Obstructive jaundice (late sign)
40
Management of PBC
- Ursodeoxycholic acid (A bile acid analogue which dampens the inflammatory response, acts as an anti-apoptotic agent, and improves cholestasis) - Fat-soluble vitamin supplementation: cholestasis impairs fat absorption - Cholestyramine - Codeine phosphate: for diarrhoea - Biphosphonates: for osteoporosis
41
Gold standard investigation for acute cholecystitis
Abdominal ultrasound - - Pericholecystic fluid - Distended gallbladder - Thickened gallbladder wall (>3 mm) - Gallstones - Positive sonographic Murphy's sign
42
Gold standard for PSC
ERCP - but has been replaced by MRCP as MRCP is less invasive.
43
empirical first line treatment for septic arthritis
flucloxacillin
44
First line treatment for withdrawal seizures
chlordiazepoxide
45
What is sjorgrens syndrome
Sjogren’s syndrome is the immune destruction of exocrine glands and often presents with arthritis, dry eyes and dry mouth. The Schirmer test involves placing a small strip of paper in the eye to measure tear production and is used in the diagnosis of Sjogren’s, alongside lacrimal gland biopsy and antibody testing.
46
treatment for ankylosing spondylitis (in order)
- NSAID e.g. ibuprofen or naproxen (2-4 weeks. If no improvement, switch to another NSAID) - Steroid - used during flares (oral, IM or directly into joints) - Anti-TNF e.g. etanercept or monoclonal antibodies against TNF e.g. infliximab, adalimumab - Monoclonal antibodies targeting IL-7 - e.g. secukinumab
47
What is pseudogout
Pseudogout is a form of inflammatory arthritis caused by deposition of calcium pyrophosphate crystals in the synovium.
48
The greatest risk factor for pseudogout
- increasing age (the greatest) - - Previous joint trauma - Hyperparathyroidism - Haemochromatosis
49
What is Reiter's triad
Reactive arthritis secondary to a Chlamydia infection. This can cause Reiter’s triad of conjunctivitis, urethritis and arthritis (can’t see, can’t pee, can’t climb tree) as well as keratoderma blennorrhagium (the rash on his feet) and mouth ulcers
50
Explain Amaurosis Fugax
Often described as a black curtain coming across the vision. A classical syndrome of painless short-lived monocular blindness. It is a term usually reserved for transient visual loss of ischaemic origin. - Occurs due to the temporary reduction in the retinal, ophthalmic or ciliary blood flow leading to temporary retinal hypoxia. - The principle cause of amaurosis fugax is transient obstruction e.g. due to emboli, of the ophthalmic artery, which is a branch of the internal carotid artery. - However, other ischaemic causes to consider include giant cell arteritis (i.e. temporal arteritis) and central retinal artery occlusion.
51
What is Polymyalgia rheumatica
is a condition that causes pain, stiffness and inflammation in the muscles around the shoulders, neck and hips.
