What is the most common reason total hip replacements need to be revised?
Aseptic loosening of hip replacement
Mx of secondary pneumothorax?
> 2cm + 50y+ = Insert chest drain
1-2cm = Aspiration, if this fails chest drain - admit 24hrs
<1cm - O2 + admit for 24hrs
When should you thrombolyse in a PE?
When there is haemodynamic instability
Hip fracture surgery - when should pts fully weight bear again?
Straight after surgery
Describe garden classification of NOFs
The Garden system is one classification system in common use.
Type I: Stable fracture with impaction in valgus
Type II: Complete fracture but undisplaced
Type III: Displaced fracture, usually rotated and angulated, but still has boney contact
Type IV: Complete boney disruption
Mx of NOF - Intracapsular / subcaptial ?
Undisplaced = internal fixation (or hemiarthroplastu if unfit)
Displaced = Total hip replacement (or Hemiarthroplasty - if not independent, cognitive impairment / not fit for procedure)
Mx of NOF - extracapsular
Extracapsular = subtrochanteric or trochanteric
Stable intertrochanteric = dynamic hip screw
Reverse oblique, transverse or subtrochanteric = intramedullary device
What medication should be avoided bowel obstruction? why?
Metoclopramide - has prokinetic properties and can stimulate persistalsis -> can worsen mechanical bowel obstruction and precipitate perforation
NSTEMI Mx?
Cluster headaches acute mx? prophylaxis?
High flow o2 + Subcut triptans
prophylaxis - Verapamil
ACS mx when should you avoid nitrates / use w caution? what should you give when medically mx instead?
PT is hypotensive as it causes widespread vasodilation
Aspirin + Ticagrelor + Fondaparinux
What to do in new onset AF presenting w/in 48h? after 48h?
Anticoagulate (heparin) + electrical cardioversion
48h+ - greater risk of clots hence anticoagulate for 3w before cardioversion
Mx of acute pericarditis?
Outpatient mx unless 38oC+ Or raised trop
NSAIDs + Colchinie are 1st line
Mx of acute pericarditis?
Outpatient mx unless 38oC+ Or raised trop
NSAIDs + Colchinie are 1st line
Acute mx of STEMI?
Analgesia
O2
Nitrates
Aspirin + Prasugrel (or clopidogrel if theyre already on a oral anticoagulant)
Acute relapse of MS - mx?
High dose oral steroids eg oral methylpred
Mx - fragility fracture in woman over 75?
DEXA scan isnt needed to dx osteoporosis - start bisphosphonate therapy
What is the treatment of choice in biliary colic?
Elective laparoscopic cholecystectomy
Inguinal hernia mx?
Assymptomatic = routine surgical referral
Signs of incarceration / strangulation = urgent surgical referral
Truss = If unfit for surgical referral
Surgery is usually open unless bilateral / recurrent in which case it is laparoscopic
Electrolyte abnormality in prolonged diarrhoea?
Met acidosis + hypokalaemia - loss of bicarb excretion from GI tract
Constant back pain + worse on movement + fever and anorexia + disc space narrowing on x-ray - dx? most common cause?
Discitis by staph aureus
What are the possible side effects of thyroxine therapy?
hyperthyroidism: due to over treatment
reduced bone mineral density -> osteoporosis
worsening of angina
atrial fibrillation
Possible interactions w thyroxine therapy and what to do?
Iron + calcium carbonate - reduces absorption of levothyroxine hence give 4 hrs apart
What is Phrens sign? what is positive in? how can you test for this?
Lifting scrotal skin from testes reduces pain - seen in epididymoorchitis -> urine void first sample for NAAT
