Q

What is often given to patients during surgery to reduce the risk of post-op infections?

where to find further guidance on this?

A

normally give single dose of one or more ANTIBIOTICS just before or during surgery

which Abx are used depend on the type of surgery an local guidelines

check trust guidelines!!

Q

PYREXIA in post-op patients:

  • possible benign causes? 3
  • investigations to consider? (5 bloods, 2 other, 3 imaging)
  • what non-infection complication should you also check for? 1
A

MILD pyrexia in first 48hrs post-op may be from:

  • atelectasis (needs prompt physio, not Abx)
  • tissue damange / necrosis
  • blood transfusion

HOWEVER have a low threshold for infection screen!!

  • FBC
  • U+E
    (- LFT)
  • CRP
  • blood cultures
  • urine dip
    (-MSU)
  • CXR

(- USS)
(- CT scan)

ALWAYS check for DVT!!!

C. DIFF:

  • what type of colitis does it cause?
  • which CLASSES of antibiotics are highest risk? 3
  • other risk factors? 6
A

pseudomembranous colitis (PMC)

CAUSATIVE ABX

  • cephalosporins
  • macrolides (esp clari)
  • fluroquinolones (anything with ‘floxacin’ - eg ciprofloxacin)

“remember that often start with C for C diff”

  • long hospital stay
  • ITU stay

Q

SYMPTOMS of C. DIFF

  • how long post-Abx do these tend to occur?
  • main symptoms? 3
A

symptoms typically appear 5-10 DAYS post-Abx therapy

1) WATERY DIARRHOEA
- resolves 1-2 weeks post-Abx
- Varies from asymptomatic carrier (1-3% all adults)→ self limiting → severe + debilitating
- Can be BLOOD stained

2) COLICKY ABDO CRAMPS

  • important bloods to get? 4
A

1) STOOL SAMPLE (get 3!)

nb this is a stool cyto toxins test - some C Diff produce toxins, others don’t - can also do culture and other fancy tests! - ask micro!

  • FBC (↑↑WCC – 80%, often v.high),
  • ↑↑CRP
  • ↓Albumin (inf/sepsis/protein losing enteropathy)
  • U+Es – essential to determine electrolyte loss

nb consider colonoscopy w biopsy if really severe!! (or think may be a DDx)

A

A-E approach

1st) ORAL METRONIDAZOLE
2nd) ORAL VANCOMYCIN

nb only indication for oral vancomycin!

nb use both if severe!

nb if asymptomatic may not need abx!

1) STOP causative abx!
2) put pt in side room
3) give fluids (PO + IV) to replace losses
4) inform public health england!!

nb Adjuvant pro-biotics, IV immunoglobulin or rifampacin used in refractory or recurrent C.diff (also Faecal transplant - Colectomy if Toxic megacolon)

3) EXTRA-ARTICULAR features:
- anterior uveitis
- skin (psoriasis)
- aortic regurg / pericarditis
- genitourinary symp (secondary to nerve compression)
- GI features (IBD)

nb (as mentioned in Q) also cause peripheral arthritis that’s generally asymmetric, and axial arthritis like sacroiliitis and spondylitis, affecting the sacroiliac and vertebral joints, respectively

nb w psoriatic psoriasis the rash and arthralgia often don’t occur at the same time and the arthrtitis can present first!

Which cancers commonly metastasise to the bone? 5

(acronym to remember this)

which are norm sclerotic lesions and which normally lytic?

A

“Lead kettle = Pb KTL”

SCLEROTIC

  • Prostate
  • Breast

LYTIC

  • kidney
  • thyroid
  • lung

nb melanoma’s also (and others)

118
Q

What is the most common primary bone tumour?

three groups of symptoms it presents with? 3

A

MYELOME (see haematology falshcards for more info!)

BONE
- eg back pain, fractures, hypercalcaemia

BLOOD
- anaemia, neutropenia, thrombocytopenia

KIDNEY
- renal failure

119
Q

What are the specific findings of these investigations for MYELOMA:

  • urine?
  • blood?
  • serum electrophoresis?
  • bone marrow biopsy?
  • x-ray? (ie type of lesions)
A

urine = BENCE JONES proteins

blood = ROULEAUX formations

serum electrophoresis = MONOCLONAL BANDS

BM biopsy =
↑PLASMA cells, plasmocytoma

x-ray = LYTIC lesions

120
Q

What is the most common presenting symptom of a primary bone tumour?

A

bone pain

pathological fractures and palpable lumps come later

121
Q

for each of these primary bone tumours:

  • osteosarcoma
  • ewing’s sarcoma
  • chondrosarcoma

state:

  • where they affect?
  • normal age of onset?
  • distinctive sign on x-ray?
A

OSTEOSARCOMA

  • metaphysis of long bone (typically knee)
  • often occurs secondary to PAGETS
  • usually 10-20 years
  • bone destruction + periosteal thickening (sun burst sign)

EWING’S SARCOMA

  • diaphysis of long bones and limb girdle
  • adolescents
  • ‘onion ring’ sign

CHONDROSARCOMA

  • malignant transformation of chondromas in axial skeleton
  • middle-aged people
  • ‘popcorn’ calcification

DON’T WORRY TOO MUCH ABOUT SPECIFIC X-RAY SIGNS, just know to have bne tumours on differential for bone pain, swelling or pathological fractures and broadly know ages!

122
Q

Systemic Lupus Erythematosus (SLE):

  • two other autoimmune conditions associated with? 2
  • four antibody tests to do? which 1 most specific?
A

A/w Sjogrens + Antiphospholipid syndrome

+ve ANA (+ve 95%)

Anti-dsDNA +ve (v.specific but only +ve 60%)

Anti-smith (most specific)

Rheumatoid Factor (+ve in 40%)

123
Q

Systemic Lupus Erythematosus (SLE):

  • typical systemic features? 3
  • typical derm features? 2
  • typical MSK features? 2
  • typical renal feature? 1
  • other parts of the body that can get inflammed? 3
  • what can often make symptoms worse? 1 (especially the derm ones!)
A

LUPUS is relapsing + remitting! (+has variable features in everyone!)

  • malaise
  • fatigue
  • fever
    (can also get lymphadenopathy)
  • malar butterfly rash (spares nasolabial fold)
  • discoid rash (red, raised plaques)
  • mylagia
  • ARTHRALGIA (90%) (non-erosive arthritis)
  • persistent proteinuria, can -> kidney failure
  • serositis
  • pleuritis
  • pericarditis

nb can also cause seizures, pancytopenia and immunological disorders

SUNLIGHT -the rashes are PHOTOSENSITIVE (ie get worse in sunlight)

124
Q

SCLERODERMA

  • aka?
  • pathological mechanism?
  • two main types? (incl speed of onset) (specific blood test for each type?)
A

aka Systemic sclerosis

autoimmune disorder characterised by ↑Fibroblast activity → ↑COLLAGEN DEPOSITION →internal ORGAN FIBROSIS + VASC DAMAGE

Limited cutaneous SSC (LcSSC) – common, slow onset, milder aka. CREST syndrome
- ACA (anti-centromere Ab)

Diffuse cutaneous SSc (DcSSC) – less common, rapid onset, high mortality
- Anti-Scl 70 (anti-topoisomerase)

DON’T WORRY ABOUT WHICH BLOOD TESTS TO GET - just know that you need to get antibody blood tests

125
Q

what are the features of CREST syndrome? 5

which of these normally presents first?

A

CALCINOSIS
- chalky nodules, may break skin

REYNAUD’S (1st in 90%)

ESOPHAGEAL DYSMOTILITY
- causes reflux + heart burn

SCLERODACYTLY
- hardening of skin on hands

TELANGIECTASIA
- aka spider veins (similar but not same as spider naevi!)

nb can also get: renal complications, erectile dysfunction, fatigue, weight loss, myalgia, fibrosis/pulm HTN, pericarditis, LVF

126
Q

ROTATOR CUFF TEAR

  • muscle in rotator that’s typically affected?
  • typical cause? (2 main RFs)
A

acute injury (young) or chronic degeneration (elderly) → rotator cuff damaged in subacromial space → tears tendon (typically SUPRASPINATUS, also subscapularis + Infraspinatus)

RF:

  • Age> 40
  • Overuse (sport/profession)

can be full or partial tear

127
Q

ROTATOR CUFF TEAR:

  • two main presenting symptoms? 2
  • typical finding during examination? 1 (nb this is v specific!)
A
  • shoulder pain
  • shoulder weakness (incl reduced range of movement)

worse with movement and at night!

PARTIAL tear = PAINFUL ARC syndrome!
- movement possible at upper bits dt action of deltoid!)

COMPLETE TEAR = abduction limited to 40-50 degs)

nb can also get clicking and catching of joint as moving it

nb treat with analgesia, ice packs, physio, steroid injections + surgery (if complete tear or not responding to Tx)

FULL range of PASSIVE movement ALWAYS present (what differetiates it from DDx)

128
Q

Main differential diagnosis for rotator cuff tear? 3

A
  • sub-acromial impingement
  • calcific tendonitis
  • frozen shoulder
129
Q

FROZEN SHOULDER

  • technical term? 1
  • common age and gender?
  • conditions associated with? 3
A

aka. Adhesive capsulitis

Most common in middle aged females

a/w DM, thyroid disease, cervical spondylosis

130
Q

FROZEN SHOULDER

- the three STAGES of the condition? how does each present and how long each one last?

A

inital symptoms develop over days!

1) PAINFUL PHASE
- shoulder pain, worse at night
- reduced active AND passive range of movement
- esp EXTERNAL rotation (< 30 degs)

2) FROZEN PHASE
- pain resolves
- shoulder remains stiff (6-12 months)

3) THAWING PHASE
- shoulder slowly regains range of movement (1-3 years)

nb Mx is NSAIDs and physio, give early

131
Q

golfer’s elbow and tennis elbow?
- which is lateral and which medial epicondylitis?

which is more common?

A

Inflammation @ the common extensor tendon arising from the lateral epicondyle or at forearm flexor muscles origin at medial epicondyle of humerus

TENNIS elbow = LATERAL epicondylitis

  • “you play LATERALLY from side to side in tennis”
  • 5x more common than golfers!

GOLFER’S elbow = MEDIAL epicondylitis
- “you want to hit straight down the MIDDLE in golf”

132
Q

MEDIAL + LATERAL EPICONDYLITIS:

  • most common cause?
  • what present with?
A

Hx of repetitive strain, heavy lifting, sports

pain and tenderness over medial or lateral epicondyl (depnding on type)
- ? often in dominant arm?

nb Mx is 6-24 months of avoiding causative activity, physio and nsaids

nb 90% recover within a year
