Q

A to E approach

A

General Approach

How do they look?

“How do you feel?”

Look at obs eg overall trends, request ECG?

Airway

Speaking = patent

cyanosed/ accessory breathing muscles, see-saw breathing

check mouth : forceps to remove, not fingers

high flow oxygen and maintain airway;

headtilt/chinlift or jawthrust: consider adjuvent if breathing only clear in this position

Gurgling/Burbling?: turn head to side (gurgling/burbling) and suction

airway adjunct if compromised (try guardal first to see how unconscious, then nasopharyngeal, lubricate, 6 for female and 7 for male)

Give high flow 15l non -rebreath. If bag mask then hold right behind jaw, not under. 12/min or 1/5-6s)

anaphylaxis?

Breathing

Look/listen/feel for resp distress (sweat, accessory muscles, cyanosis)

RR (>25 may deteriate suddenly)- Count for 1m

assess depth and pattern, ueven expansion?

chest deformity? abdominal distension? raised jvp?

record sats and o2 levels (does not detect hypercapnea)

breath sounds (rattle (secretions not clearing), wheeze, stridor)

percussion

Auscultate (bronchiol breathing indicates consolidation)

position of trachea

chest wall crepitas

all critically ill get a non rebreath mask 15L/min

Can step down to Venturi 28% mask (4 L min-1) or a 24% Venturi mask (4 L min-1) initially in COPD and reassess

if depth of breathing inadequate use bag mask and call for specialist help

nebs can give 6 litres max but add 5l via nasal canula

Circulation

Temp

HR - count for 1 min (weak central= poor cardiac output, bounding = sepsis

BP

are they septic?

Quick cardio exam: temp, CRT, Pulse, heart sounds, oedema

Oliguria = sign of poor cardiac output

external/internal bleeding?

cannulate

IX; All get FBC, U&E, LFTs

Major harmorhage protocol = call blood bank or 2222 . . will need trained runner

then specific:

Sepsis: CRP, lactate, blood cultures

Haemorrhage or surgical emergency: Coagulation and cross-match

Acute coronary syndrome (ACS): Cardiac enzymes

Arrhythmia: Calcium, magnesium, phosphate, TFTs, coagulation

PE: D-dimer (depending on Well’s score)

Overdose: Toxicology screen

Electrolyte imbalance: Calcium, magnesium, phosphate

Ruptured ectopic: Coagulation, cross-match, ß-HCG levels

Anaphylaxis: Consider serial mast cell tryptase levels

ECG, Cathetarisation, bladder scan, pregnancy test, swabs/cultures?

3 lead ECG = red/right, lemon/left and green/spleen

Hyovolemic? - MC . . . IVF to all cool peripheries and tachicardic

Lay patient supine and raise legs if appropriate

Give 500ml bolus Hartmann’s solution/0.9% sodium chloride (warmed if available) over 15 mins

In heart failure: Give 250ml fluid as above; check the chest for crackles after each bolus as there is a risk of fluid overload and pulmonary oedema

Repeat up to 4 times (2000ml/1000ml), monitoring response

assess BP q5mins aiming for thir normal or >100

Stop and seek help if the patient has a negative response (e.g. increased chest crackles).

Seek senior help if the patient isn’t responding adequately to repeated boluses.

ACS : ECG,po aspirin 300mg, subliguial glyceryle trinitate spray/tablet, oxygen, morphine + antimimetic,

Disability

Consciousness;

repeart AVPU (alert, responds to voice, responds to pain, uresponsive)

assess pupils (pinpoint opioids, dilated = intracranial pathology of TCA overdose)

PEARL = pupils equal and reactive to light

Check for head injury while you are here

calculate GCS (<= 8 = anaethetist or crash team)

Movement: ‘squeeze my fingers

check drug chart (opioids, sedatives, anxiolytics and antihypertensives)

Causes of decreased consciousness:

Hypovolaemia

Hypoxia

Hypercapnia

Metabolic disturbance (hypoglycaemia)

Seizure

Raised intracranial pressure/other neurological insults

Drug overdose

Iatrogenic causes (e.g. administration of opiates for pain relief)

DIABETES Blood glucose (4.0-11.0 mmols/L)

check ketones if >15

<4 give 50ml 10% dextrose - give every minute till 250ml if no response

urine dipstic?

imaging?

Exposure

Any pain?

Bleeding? - rate/ amount .. . . ax for shock

rashes? coagulopathy/infection

calves - red swollen dvt?

Lines - any concerning?

Cathetar- puss or blood?

surgical wound?

drains- pus? blood? high/low output?

Reasses . . . who can help?

Full hx from pt or collateral

r/v notes - esp vital signs and meds

lap results?

What care? HDU? ICU?

Notes and SBAR handover

keep realtivesinformed

Q

Antibiotic Ladder

A

Rules

  1. If sick go broad
  2. Escalate Rapidly
  3. Descalate slowly
  4. Target Cultures and Sensitivies
  5. Empiric treatment - use the lowest possible

Amnionpenicillins = g-ves etc but with b lactimase inhibitors has some +ve coverage

Cephalosporins

1st - cephalexin, cefadroxil, cephradine (strep and MSSA)

2nd-

3rd - Ceftriaxone (Strep and g +ves)

4th - cefeprime (pseudomonas coverage)

amoxicillin clavulanic acid = co-amoxicillin

Pip-Taz = Piperacillin/tazobactam aka tazocin

Tic-sulb = ticarcillin sulbactam

Aztreonam - would only jump to if severe beta lactam allergy

Daptomycin used in blood stream

Linozolid for lung infection

Fluroquinolones - need to go through each base? - used to be good for UTIs but now for pseudomonas coverage

levofloxacin ver specific infections

moxifloxacin - respiratory fluroquinolone but do not use.

IV gentamicin, amoxicillin & metronidazole: Also known as ‘triple therapy’, these antibiotics are often used together in severe intra-abdominal infections.

TMP/SMX = co-trimoxazol

Animal Bite = co amoxiclav

Q

Pneumonia

A

Fever and cough = CXR and Sats for everyone

ABG if low sats

FBC - neutrophilia in bacterial

U&Es for dehydration and curb 65

CRP - raised in response to infection (<20 no abx, >100 abx, 20-100 consider delay)

Blood culture should do but only returns 10% of time and does not really alter tx

Sputum culture is low yield and we tx empiracally anyway

Nothing? - bronchitis aka atypical pneumonia (CAP lite)

-PO abx

Cavity lesion?

  • usually malodorous sputum

differentiate with CT chest

Tx 3rd gen + G+ve and anaerobic coverage (clindomycin)

Consolidation?

Pneumonia

Differentiate with Time relation to hospital building

Empiric tx depending on category

Low severity community = amoxicillin (macrolide/tetracyclin if pen allergy)

more severe = Amoxacilin + macrolide (7-10d)

  • consider co amoxiclav/ ceftriaxone / piperacillin with tazobactam and a macrolide

Admit?

-CURB 65 score

Confusion (AMT <=8)

Urea >7 mmol/L

RR>30/min

BP <90/60

>65yo

0 mx in community

1 - SATS and community CXR

2- MX in hospital

4 = 30% mortality by 30days

CRB65 in community - 2 = go to hospital

PCP

HIV+ve (immunosuppressed)

not solid consolidation but patchy diffue infiltrates

longer subacute presentation

ix silver sputum stain (not culture)

Tx with co trimoxazole

Give steroids if hypoxaemic

FLU

Myalgia giveaway

confirm with swab

prevent with vaccine

presdisposes to S.Aureus pneumonia

AND

Klebsiella ax with aspiration (MC righ lower lobe)

H.flu = COPD or smokers

3RD gen cephalosporin = ceftriaxone

Imaging

  1. Pneumonia
  2. PCP
  3. Abscess

Mycoplasma Pneumonia

Associated erythema multiforme

tx: doxycycline or a macrolide

Allergic Bronchopulmonary Aspergillosis

IX: po glucocorticoids + itraconazole

Legionella Pneumophilia

flu-like symptoms including fever (present in > 95% of patients)

dry cough

relative bradycardia

confusion

Q

AKI full

A

Pre

PUMP = mi and chf

Leaky - also a bit CHF but think OSI

Hole : diuresis, dehydration, diarhoea and haemorhage

FMD (fibromuscular dysplasia) = young woman with secondary htn and renal failure

RAS (renal artery stenosis) = old man with atherosclerosis

Renal

RBC casts = glomerulonephritis - BUT r/o nephrotic syndrome (triad)

AIN - itis . .. look for infections. Look for WBC casts or eosiophils

but also some drugs (TMX-SMP, penicillins, cephalosporins)

ATN - muddy brown casts (not sensitive or specific)

Things in tubules coming into contact and damaging them

two main types (ischamia and toxins) prevent with IVF

Three main phases

Post

hydroureter/hydronephrosis

depends on level of obstruction (both kidneys = urethra. . only one dialted = ureter)

more causes the lower down you go

neurogenic = nerve damage or medications

foley kink

Approach

PRE

first rule this out

U:Cr >100 / Urins sodium <10 = pre-renal

give IVF if hypovolaemic

give diuresis if hypervolaemic

Post

Then rule out this

US or CT scan (CT better for stones)

then relieve obstruction

intra

hx/physical/UA usually enoght

eg DM with glucose and protein = diabetic nephropathy

Might need bx occosionally to prove dx

AEIOU = indications for dialysis

Staging

AKI is staged according to the serum creatinine changes, and/or the production of urine.

1 = Increase 1.5-1.9x baseline or < 0.5ml/kg/h for >6 consecutive hours

2 = Increase 2.0-2.9x baselinem or < 0.5ml/kg/h for >12 consecutive hours

3 = Increase > 3x baseline or >354 µmol/L or < 0.3ml/kg/h for > 24h or anuric for 12h

Extra

Stop NSAIDs in AKI as can worsen

Renal replacement therapy indications: (i) fluid overload that is refractory to diuresis, (ii) hyperkalaemia refractory to medical therapy, (iii) metabolic acidosis (pH <7.1) and (iv) complications arising from uraemia (e.g. encephalopathy, pericarditis).

Q

Brain Inflammation

A

Fever + HA raise suspician (in real life maybe general innfection) - Photo/phono further raises this

Meningitis MC general bacterial unless specific clues

AMS for encephalitis (encephalitis leads to encephalopathy)

Encephalitis = 1000s and all just need supportive tx

  • except HSV which is common and can be tx

FAILS - do not do if any one of these (brain will herniate through foramen magnum and die)

Immunosuppressed = elderly neonate who is on monoclonal antibody chemotherapy for their HIV

Unsafe you give Abx THEN CT scan (better a bad diagnosis and alive pt than dead pt and good diagnosis)

1000s of WBCs and mostly polys = bacterial . .. if not then consider something else (can still be bacterial)

No corticosteroids in suspecting bacterial meningitis if <3 months

Mass

cannot LP

HIV/AIDS - Tx for toxoplasmosis

Lymphocytes

temporal lobe/ haemoragic tap = HSV on test but means nothing in life

Cryptosporogenes Tx with Amphotericin

Lymes = Tx with ceftriaxone

TB tx with RIPE

Contact prophylaxis

Meningococcal Meningitis ciprofloxacin or rifampicin

Neisseria meningitides MC children (5% develop neurolgical sequlae and 10% mortality)

Men B 60% of meningococcal disease

Men C for 40%

the rest from travel/ uni

Neontes: Gp B Strep, E Coli, Listeria, Pneumococcus, Staph aureus.

In babies over one month and children, causes include: Meningococcus, Pneumococcus and Haemophilus influenzae B

Q

UTI

A

General

Typically ascending infectino from urethra to kidneys (higher = worse)

MC young woman with contraception (having sex) and men who penetrate the anus

Uncomlicated must be a non pregnant female

Comlicated = the Ps

E.coli 85% of the time

klebsiella and proteus = other enteric GNR

Cloudy offensive urine

U/A and urine culture = the go to tsts

(>10 WBC/ high powered field)

CT/ US to ix more serious

(>10 to the 5 colonies)

Urethritis

Not really UTI but STD

gonorrhea = chlamydia (ie if you find one then you tx the other)

test urine sample now (first void urine sample NAAT test)

Gonnorhoea = IM ceftriaxone (ciprofloxacin if its known to be sesnitive)

Chlamydia = 7d Doxycycline (azithromycin if not tolerated)

HIV screen

Asx Bacteriuria

should only really be for regant or prepp for urologic procedure ( no-one else should be tx)

Tx with nitrofurentoin (amoxacillin/cefalexin 2nd line) - 7days

repeat to see if tx (only one that you repeat test)

nitrofurentoin can cause neonatal haemolysis near to term so use amoxacillin instead

Cystitis

MC young women

U/F/D (urgency, frequency and dysuria) w/o systemic symptoms (in life you can of course get sepsis from this)

Can choose the abx (TMP-SMX if CKD) but decide how long for

complicated - 7day in uk

Men get abx straight away, woman have back up prescription if not improved in 48hrs

Pyelonephritis

U/F/D but with systemic sx

CVA = costrovertebral angle

WBC casts = give away

urine culture here as long course of abx

Can give PO ciprofloxacin if ambulatory (young and still getting around but still all the sx)

want to admit them to see if perinephritic abscess

Perinephric abscess

(walled off or in parenchyma itself)

suspect if don’t improve after 72hrs confirm with US/CT

Children

Maybe more generalised sx

<3months refer to paediatrician and admit if upper UTI

>3month then usual 3 day

Q

Plasma cell dyscrasias

A

Monoclonal exansion of plasma cells in BM

Multiple Myeloma = Most important

  • -Raised ESR and osteoporosis represents multiple myeloma until proven otherwise*
  • -raised calcium and bone pain = myeloma until proven otherwise*

Incomplete IgG

BM becomes crowded and good plasma cells not made so prone to infections

Protein gap on LFTs

Spep = serum protein electrophoresis (M spike)

IgA, IgG

Immunoglobulins: The most common type of heavy chain produced in myeloma is IgG, followed by IgA and then IgD. IgM myelomas are rare, but when IgM is elevated in the blood, the patient more likely has a related disorder, known as Waldenstrom’s Macroglobulinemia.
As MM progresses you get more light chains than heavy (more light chains = more aggressive)

A Bence Jones protein is a monoclonal globulin protein - deposits in kidneys so use Upep (M spike)

Osteoclast stimulating factor leads to Lytic lesions and subsequent pathological fractures

-detect with seletal survey (not bone scan) . . . do with MRI body (CT if not possible)

CRABBI

Calcium

  • Hypercalcaemia occurs as a result of increased osteoclast activity within the bones*
  • This leads to constipation, nausea, anorexia and confusion*

Renal

  • Monoclonal production of immunoglobulins results in light chain deposition within the renal tubules*
  • This causes renal damage which presents as dehydration and increasing thirst*
  • Other causes of renal impairment in myeloma include amyloidosis, nephrocalcinosis, nephrolithiasis*

Anaemia

  • Bone marrow crowding suppresses erythropoiesis leading to anaemia*
  • This causes fatigue and pallor*

Bleeding

bone marrow crowding also results in thrombocytopenia which puts patients at increased risk of bleeding and bruising

Bones (middle/lower back, ribs and hips)

  • Bone marrow infiltration by plasma cells and cytokine-mediated osteoclast overactivity creates lytic bone lesions*
  • This may present as pain (especially in the back) and increases the risk of fragility fractures*

Infection

a reduction in the production of normal immunoglobulins results in increased susceptibility to infection

Chemotherapy often with melphalan and steroid (dexomethasone) and EITHER thalidomide (if no autologous stem cell transplant) or bortezomid (if being induced for autologous stem cell translant)

<70 possible stem cell transplant

also zolondric acid for fractures, VTE prophylaxis, vaccinations, ig replacement

Monoclonal Gammopathy of uncertain significance

monitor for conversion (2% a year)

usually die before this

key is <10%

Waldenstrom’s Macroglobulinaemia

IgM so can form petamers which lead to hyperviscosity

Key is >10% LYMPHOMA ie lymphoplasmosidic lymphoma

Constitutional sx = night sweats, fevers ,weight loss

tx rituximab based chemo

tx the hyperviscosity with plasmaphoresis

Q

Approach To Anaemia

A

Symptoms represent severity not type of anaemia

Men: 135-180 g/l Women: 115-160 g/l

More 100 usually asymptomatic

HOHF = high output heart failure

<80 pallor of skin and anterior rim

Delivery of O2 = Cardiact output * Hb * SATS - depending on your reserve you exerience sx differently

It also depends on how quick the loss in hb happens

Micro and Macro = mostly production anaemias (low reticulocyte count)

Normocytic mostly destruction anaemias (increased retiulocyte count)

Megaloblastic (Impaired DNA synthesis) looking for hypersegmented neutrophils (5+ lobes)

If B12/Folate levels not clear can request methylmelonic acid to differentiate.

Normocytic

Haemolytic or haemorhage

Haemorhage = increase LDH, decreased haptoglobin, increased bili

Haemorhage you should see evidence so find and plug

MDS = myelodysplasic syndrome

Q

Sodium

A

Moderate symptoms: nausea, confusion, headache

Severe symptoms: vomiting, cardiorespiratory distress, severe somnolence, seizures, coma (GCS = 8)

Acute (<48hrs)

Severe = <125 with severe symptoms = consultant management only in with close observation ICU, HDU, Resus or maybe AMU

Moderate = <129 with mooderate symptoms

aim is to stop further decrease (stop diuretics, acei and hypotonic fluids if possible)

if strong suspician of new onset symptoms consider IC hypertonic saline (consult a consultant) aim to increase by 5 every 24hrs but no more than 10 in 1st 24hrs or 8 thereafter, receck at 1, 6 and 12 hrs

non-symptomatic = <135 without severe or moderate sx (stop further decrease as above) further mx is dx specific as there is time.

Chronic (>48hrs)

USE HANDBOOK for dx
ix: if possible, stop diuretics/angiotensin-II antagonists/ACE-inhibitors for 48 hours and then measure serum and urine osmolality, and urinary sodium. Assess clinically for volume status.

Hypovolemic tx = stop relevent drugs, IV nacl, 100mg IV hydrocortison if clincial suspician of adrenal insufficiency

euvolemic tx= stop relevent drugs, water restric 1 L/day, oral sodium chloride (slow sodium) +/- low dose furesemide, consider demeclocycline

hypervolemic tx = tx underlying cause, sodium restrict, fluid restrict 1l/day

Monitoring: CNS observations and reassess every 6 hrs till stablised?

HYPERNATRAEMIA

causes: diarrhoea, vomitting, burns, nephrogenic/central diabetes insipidus, glucosuria eg dM, excessive iV sluids, lithium, phenytoin, demeclocycline and corticosteroids

Mild = <155 (drinking may be enough)

severe/hypovolemic = > 155 with salt and water loss

tx: initially hartmann’s until haemodynamics stabalised then correct with 0.45%

Severe hypernatraemia/dehydration (water loss >155mmol/l)

tx: slow infusion of sodium chloride 0.45% or glucose 5%

Q

AKI Guidelines

A

Prevention

At risk = elderly, diabetic, hypotensive and septic pt

Keep well hydrated

Recognition

Cr = 1.5x baseline

1 = Increase 1.5-1.9x baseline or < 0.5ml/kg/h for >6 consecutive hours

2 = Increase 2.0-2.9x baselinem or < 0.5ml/kg/h for >12 consecutive hours

3 = Increase > 3x baseline or >354 µmol/L or < 0.3ml/kg/h for > 24h or anuric for 12h

clarify what type and reasoning

presence or absence of immune sx (rashe, new arthritis, nasal crusting/bleeding, haemoptysis, bew deafness, mouth ulcers, alopecia, iritis/episcleritis, mononeuritis or neuropathy)

Obstructive sx? FUD, poor stream, hesitancy,, nocturia, PV bleeding, stones

Examination and Observations

Fluid status exam (inc autoimmune)

Urine Dipstick (all AKI, non dialysis CKD, DVT &PE , oedematous pt and suspected UTI)

fluid input/output (cathetarise if this is hard)

send MSU if urinalysis abnormal

send urine protein creatinine ration if protein >2+

Investigations

daily U&Es, bone profile and bicarbonate until fxn improving

autoimmune screen if glommerulonephritis/vasculitis suspected

urine sodium if oliguric (<20 implies pre-renal)

Renal US:

  • urgent if >3x or > 400 or obstructions suspected
  • non-urgent if 1.5-3x or suspected GN
  • may not reed if recovering function or US in last 6 months

Management

Stop nephrotoxic drugs (NSAIDs, ACEi, ARB, pottassium sparing diuretics)

Diuretics should only be suspended if hypovolemic

Stop metformin if eGFR <30

optimise fluids

treat infection promptly

suspected vasculitis/ renal syndromes are a renal emergency (call nephrologist)

30% increase in Cr acceptable on starting RAAS inhibitor (ARBs/ACEi)

Q

Calcium Aetiology and Mx

A

PT glands behind thyroid

PTH released by dishinibition of Ca receptors

PTH acts on gut indirectly via Vit D- 1,25 which tells gut to reabsorb Calciuma and phosphate (1 alpha hydroxylase)

kidney resabsorbs calcium and extrets phosphate

Clasts breakdown bony matrix releasing calcium and phosphate

Albumin

only 1% free (as ionised calcium)

every one change in albumin = a change in the opposite diection of calcium (from normal)

Hypocalcaemia Management

Check if symptoms

Trousseau = capal pedal spasm on cuff inflation

Chvostek = Tapping (no dulling of reflex)

Prolinged QT interval on ECG

Hypercalcaemia Mx

‘bones, stones, groans and psychic moans’

corneal calcification

shortened QT interval on ECG

hypertension

Increased risk of pseudogout

Moans = AMS

Groans = abdo pain

Sx then tx straight away with IVF (solution to polution is dilution) and Bisphosphonates

Calcitonin (calcium turn down) if severe

Can add loop directics (block calcium reabsorption) when volume resiscitated (or it could make it worse)

Q

Hypercalcaemia Diagnosis

A

Hyperthyroidism MC

Primary - One hyperfunctioning

Tertiary = all Hyperfunctioning

Secondary = Appropriate response to relative hypocalcaemia in early kidney disese GIVE CINACELCET (calcium mimicker) to prevent tertiary

IX

Differentiate with Sestamibi Scan (technetium-MIBI subtraction scan)

Xray may show pepperpot skull

High calcium and as kidney is functioning it wins

brown tumours = unique to parathyroidism (not really malignancy by eat away at bone)

Tx with resection but watch out fo hypocalcaemia as remainiong PT glands atrophied as suppressed

calcimimmet compounds if unsuitable for surgery

Hypercalcaemia of cancer

Ca inhibits PT release therefore kidneys do not win

PT related protein acts on kidney so Kidney wins

differentiate with phosphate

Hypervitaminosis D

Can see with ingesting in practice

Granulomatous disease increase completed 1,25 vit D produciton so kidneys absorb more calcium an phosphate so

TB and Sarcoid presentation

Hypercalcaemia of immobility = rare, ASx ,old person, trauma, immobility with hypercalcaemia

Familial Hypecalcaemic hypocalcinuria = benign

First ones = big derangements and last = small derangements

Thiazide diuretics can cause hypercalcaemia

Bone Mets Cause

MC source: Prostate>breast>lung

MC site: Spine>Pelvis>Ribs>Skull>Long bones

Q

Hypcalcaemai diagnosis

A

MC Thyroidectomy (oopsy) or appropriate repsonse to parathyroid resection

AI = very rare

tetany/perioral tingaling = post op day 1

phosphate irrelevent as no pth so no reabsorption or secretion

parathyroid should switch back on with time (or supplement with PTH in future)

Pseudoparathyroidism

end organ resistance to PT so as if its low

HIGH PHOSPHATE not low

Vit D deficiency

poor dairy intake or not going outside

Diagnose with 25 -vit D

Bisphosphonates if significantly osteopenic

Acute hypocalcaemia in pancreatitis is due to sequestration and is an ominous sign

CKD

early = impaired vitamine D formation

Cinacalcet to prevent tertiary

Late = Hyperphosphataemia

EXTRA

Prolonged QT interval on ECG

Q

HF approach

A

Left HF - backs up to lungs

Right HF- backs up to body

often mixed

SX - RHF - peripheral oedema, hepatosplenomegally, raised JVP . . . dyspnoeea etc from hypoperfusion

  • liver = firm, smooth, tender and pulsatile liver edge

LHF - Dyspnea, orthopnea, paroxysmal nocturnal dyspnoea, crackles, S3

IX - BNP>TTECHO>Left heart cath (ischaemic or not)

1st line N-terminal pro-B-type natriuretic peptide (NT‑proBNP)

High = > 2000 pg/ml (236 pmol/litre) = TTE <2w and specialist assessment

Raised = 400-2000 pg/ml (47-236 pmol/litre) = TTE <6w and specialist assessment

Normal = < 400 pg/ml (47 pmol/litre)

BNP levels different (H= >400, R = 100=400 and N<100)

TX

Annual influenza vaccination

One off pneumococcal vaccine

check U and Es 2 weeks after ACEi or Spironolactomne started

1st line ACEi and Beta blockers (bisoprolol, carvedilol, and nebivolol)

If still symptomatic and LVEF <35%:

second line ARBs and aldosterone antagonist (spironolactone/eplerenone) - cause hyperkalaemia along with ACEi

If still symptomatic and LVEF <35%:

Third line ;

ivabradine, sacubitril-valsartan, hydralazine in combination with nitrate, digoxin and cardiac resynchronisation therapy

Diuretics for managing fluid overload but no change in mortality

Aspirin and statin if know ischaemic cause

Pacemaker if <35% but not stage class IV

Class IV- bridge to transplant

Acute bloods for anaemia, infection, electrolyte imbalance . . . . BNP >1mg/L supports diagnosis

NYHA classification

Stage I - No limitation on ordinary physical activity (incorrect)
Stage II - Normal at rest. Ordinary physical activity causes breathlessness (correct)
Stage III - Normal at rest. Less-than-ordinary activity causes breathlessness (incorrect)
Stage IV - Symptoms at rest. (incorrect)

Extra

Measure digoxin levels 6hrs post dose

XRAY:

A - alveolar oedema (bat wing opacities)

B - Kerley B lines.

C - cardiomegaly.

D - dilated upper lobe vessels.

E - pleural effusion.

Q

CKD

A

Diagnose if eGFR is <60 on 2 consecutive prsentations. Do yearly U+Es and ACR

remember ACEi can decrease by 25%+. nsaids can affect too

consider referal 3b and down or if complications start

  1. Stage it (when to dialysis)
  2. Prevent Progression
  3. Mx Complications

US: bilateral enlarged in diabetic nephropathy, shrunken in other types

Staging

Assume stable Cr so eGFR not reliable in AKI

ESRD = essential anuric

stage 1 - evidence of CKD but normal eGFR

Stage II usually asx

stage III you see start of complication mx here

stage IV means ESRD inevitable so prepare with a AV fistual (matures over months . . . at least 8 weeks)

HD = 4 hours three times a week

PD = every night via peritoneal cathetar

Renal transplant final option

eGFR innacurate in extremes of muscle mass

Prevention

Prevent progression at every stage

Htn

want tighter targets with ACE-I

ACE-i reduce filtration pressure therefor decrease of eGFR by 25% or increase in Cr of 30% acceptable

Can also use furesomide

DM

same goals as everyone else

do not use metformin as causes lactic acidosis

target <48 mmol/mol (6.5%)

Proteinuria

covered by ACEi/ARB + low protein diet

measure via albumin:creatine ratio via a 1st pass urine spot sample

if > 3 significant and > 70 mg/mmol should be on ACEi regardless of htn

Hyperlipidaemia

atorvastatin 20mg offered to all CKD - increase dose if 40% reduction not achieved

  • <30ml/min should be mx by renal specialist

Complications

anaemia of CKD

due to EPO

dx by R/O other causes of normocytic anaemia and malnutrition (iron/folate/b12)

Tx with Fe (PO or IV)

EPO - ESAs (erythropoiesis-stimulating agents) such as erythropoietin and darbepoetin

may need transfusions

secondary hyperparathyroidism and mineral bone disease

phosphate stimulates PTH release in attempt to eliminate via kidney but kidneys unable to

Ca low as kidney cannot stimulat 1, 25 vitamine D so not absorbed

Phoshate binders =sevelamer

calcimimetics (cinecalcet) . . . act as calcium and reduce PTH

also replace Ca and vitamine D (alfacalcidol, calcitriol)

want to prevent osteopenia and pathological fractures

Volume overload

prevent with Loops (can add in thiazide later on)

not uncommon to see stage IV on furosemide and metalozone ot get the last out of kidneys

Metabolic acidosis. . . bicarb usually settles around 10-20 . . .. give po sodium bicarbonate to stop metabolic acidosis

Drugs to avoid in renal failure

antibiotics: tetracycline, nitrofurantoin

NSAIDs

lithium

metformin

Q

COPD MEDED

A

If they have Asthma too it should have already been diagnosed

Bronchitis - low o2 leads to hypertension and RHF

Emphysema - damaged aveoli and co2 retension - cachexic and prolonged forced expiration

Diagnose - Spirometry. .. . . the other stuff is for acute

Asthma: raised eosinophil count +/- diurnal variation +/- peak flow varition over time (at least 400ml)

FEV1/FVC = <0.7

FEV1 of predicted for severity

->80% =mild stage 1

50-79 = moderate stage 2

30-49 = stage 3 severe

<30% = stage 4 very severe

Simplified drugs

beclometasone, formoterol and glycopyrronium (Trimbow) - triple therapy in one for better compliance

Non asthmatic = SAMA + LABA + LAMA

Asthmatic = LABA + ICS (can add in LAMA if refractory

Mucolytics for productive cough

SABA = Albuterol (can also use SAMA first line in uk but need to switch to SABA for second line)

LAMA = ibatropium (2ND line ICS+LABA instead if asthmatic features)

LABA- ending in -alol

COPDER - long term management

O2 and smoking cessation = only things that prelong life (and colume reduction surgery in some patients

O2 - 88-92%

  • -long term - IX if FEV1 <30%/cyanosis/raised JVP*
    • 2 ABG 3w apart offer if <7.3 kPa or 7.2-8 and peripheral/pulmonart oedema or polycythamia*

Exacerbation

ECG, ABC, CXR important to see if anything else causing

Add ABX if sputum looks infected. Cycle between doxycycline (ruin teeth) and azithromycin (QT prolongation so check ECG first)

  • azithromycin used for prophylaxis in UK
  • amoxicillin, doxycycline or clarithromycin for acute in UK

Causative organisms

Haemophilus influenzae (most common cause)

Streptococcus pneumoniae

Moraxella catarrhalis

IX

The following investigations are recommended in patients with suspected COPD:

post-bronchodilator spirometry to demonstrate airflow obstruction: FEV1/FVC ratio less than 70%

chest x-ray: hyperinflation, bullae, flat hemidiaphragm. Also important to exclude lung cancer

full blood count: exclude secondary polycythaemia

body mass index (BMI) calculation

Ventilation

Non invasive ventilation benefits pts with pH 7.25-7.35

also indicated if respiratory acidosis persists despite maximal standard medical therapy for 1 hour or more

Invasive ventilation if pH <7.25

Q

PE

A

Common, high mortality, extensive topic

Continuous with DVT

Need Vircow’s Triad to get DVT

1-

2- eg central lines or smoking

3- COCP, coagulopathy, malignacy

CALF SIGNS = NO DIAGNOSTIC VALUE

  • unilateral odema >2cm

Retinal haemorrhages and intra-arterial fat globules on fundoscopy can be assoicated with fat embolsim

2 Level DVT wells score

=>2 = DVT likely

<=1 do D-dimer to rule out

Post Thrombotic Syndrome

Complication following DVT

painful, heavy calves, pruritus, swelling, varicose veins, venous ulceration

tx with compression stockings

Wedge Infarct

can see on CXR

Ischaemia - pleuritic chest pain

  • Pulmonary hypertension from pushing against clot

Hypoxaemia from decreased perfusion

S1Q3T3 - indicates rs heart strain (also new RBBB associated with PE)

Haemodynamically unstable + Right Heart straign indicates massive PE (thrombolyse them)

Body’s response (why PE size not important)

  • platelet mediators spread over lungs leading to vasodilation and fluid to leak out
  • O2 diffusion limited so hypoxaemia develops
  • hypoxaemia leads to tachyC/P
  • co2 perfussion limited so decreases with rachypnoea

-hypocapnaeia/alkalaemia develop
therefore Blood gas = hypoxaemia with respiratory alkalosis

IX (NICE)

ABG, ECG, CXR

Blood: fbc, u+es, clotting screen and G+S

Use well’s criteria to

>4 CTPA (ie >=5)

-V/Q scan if renaly impared and CXR clear (needs to be able to visualose ventilation)

=<4 = D-dimer to rule out (>50yo you need to age adjust)

tPA - massive PE eg drop in BP (can give IVF also). if haemodynamically unstahble after fluid challenge can consider POC echocardiogram ix right ventricular strain or to visualise thrombus. tPA (eg alteplase) also considered for haemodynamically stable patients with severe right ventricular dysfunction, extensive clot burden and cardiopulmonary arrest due to PE

if cont. haemodynamically unstable after tPA can consider cathetar directed or surgical embelectomy.

Submassive PE = RHS (ix with trop, bnp and echo) but haremodynamically stable

Massive = RHS + Haemodynamically unstable

-sit up, give 15L o2

IVC filter (eg DVT likely to kill and GI bleed)

The warfarin bridge is 5d/ when INR 2-3 (whichever longest)

NICE - GIVE DOAC straight off if PE likely its not contraindicated as can just cont. after - apixaban, rivaroxaban

ROH Process

Gestalt assessment = unlikely then rule out with PERC assessment

if not then Wells score (d-dimer to rule out if negative (adjust if >50))
CTPA unless <35 or pregnant/breast feeding
if can do within 4 hours then wait for treatment, if not then tx straight away

provoked? main =surgery, major trauma, pregnant or puperium, Hormone treatment (pill or HRT), immobility (bedbound, unable to walk or proprtionate part of day in bed/chair)
all unprovoked should be offered cancer screening

DOAC for most unprovoked
LMWH in Ca, pregnancy, breast feeding, eGFR <15

Lifelong = warfarin

egfr <5 = unfractionated

Q

GI bleed Approach

A

Can’t rely on sx as some variation

  • even upper can present as haematocetzia

Call GI when stabalised

  • minimal : FBC, U&Es, LFTs, clotting, obs, crossmatch

Give Terlippressin before OGD in varicies

OGD all suspected upper GI within 24hrs of admission (first gastrographin/ barium in borhaeves)

NICE says you don’t need to do IV PPI but conflicting evidence so many still do

Mallory weiss = weekend warrier. does not usually vommit

Boorhaeves = professional vomitter

Lower GI you want to find source of bleed. . .. based on rate of bleed (hypotension?). rapidly decreasing HB?

Mesenteric Ishcaemia = ‘gut attack’ POOP (pain out of proportion to examination) - pain after meals is like angina to the heart. colonoscopy looking for ischarmic tissue.
Colonic ischaemia = watershed areas in hypotensive patient. This would be a painful bleed after someone becomes hypotensive for another reason. colonoscopy

Haemorhoids - Internal = painless + blood (not mixed in)

external = painful - blood

glasgow-blatchford bleeding score

assess upper GI bleed severity

1-6 each graded on points

>8 ICU admission

Score is “0”only if all the following are present :

  1. Hemoglobin level > 12.9 g/dL (men) or > 11.9 g/dL (women)
  2. Systolic blood pressure > 109 mm Hg 3. Pulse < 100/minute
  3. Blood urea nitrogen level < 39 mg/dL
  4. No melena or syncope
  5. No past or present liver disease or heart failure.

ROH Approach

A to and oxygen

2 large bore cannulas : FBC, U+Es, LFRs, Clotting, VBG, crossmatch 6 units

arrange blood transfusion/ give crystalloid vs major haemorhage protocol

correct coagulopathy (plts \> 50, vit/ffp, reverse anti-coags)
Varicell bleed + 2mg IV terlipressin, 4.5g pip-tazo, metoclopromide 10mg

escalate to med reg or GI consultant

discontinue NSAIDs, aspirin and antiplatelets

Q

Microcytic Anaemia

A

Go to iron studies

Silo metaphor

  • tap/ output release to blood
  • ferritin = iron stores

TIBC = room in the silo

Iron in from diet (mainenance is 1g . . . can take in max 3-4g)

Menometrorrhagia = prolonged or excessive uterine bleeding occurs irregularly and more frequently than normal.

IDA (iron deficiency anaemia)

1st line ix all IDA should be screened for coelic disease

slow bleed think:

  • old man colon cancer
  • young woman menometrorrhagia

BM biospy definitive but don’t do

silo slowly runs out

stool softeners to prevent constipation

If before surgery can give transfusion or IV iron (ferric carboxymaltose) 1g

ACID = anaemia of chronic inflammatory disease

our cells can survive longer w/o iron than bacteria therefore defence mechanism

silo tap turned off but continues to fill

Look for chronic inflammation eg RA/ Lupus

often no tx needed if asx - EPO if needed

Thalassaemias

Iron studies and silo normal

Do electrophoresis - As with something else = Beta thalasaemia

Normal = Alpha thalassaemia (beta does not bind with other)

4 copies of each gene - just one = won’t notice and all 4 = dead so have mild (don’t treat) and severe (transfusion)

tx the iron overload w deferoxamine (undo iron from me)

Beta Thalasaemia trait: disproportionatly low MCV and HbA2 raised (> 3.5%)

Sideroblastic

Increased Fe with everthing else normal l l loften show photo of BM biopsy showing ring sidoblasts (iron stuck in mitochondria)

Divide into reversible and non reversible

B6 - cannot tx with B6

MDS - Myelodysplasic syndrome

Q

Arhythmias

A

Palpitations? - exclude arrhythmias with Holter Monitering (24hr potable 3 lead ecg)

fast = tachycadia?

Narrow = <3 boxes (0.12s) - wide is >

Adenosine = 6mg then 12 then 12 (IV adenosine needs to be infused via a large-calibre vein or central route)

Ventricular Fibrillation

MC cause of death following an MI

SVT

no p waves, HR>150, regular

if haemodynamically stable do vagal manouvres

if this fails give IV adenosine 6mg>12mg>12mg (veramapril if asthmatic)

AF

no p, irregularly irregular, <150

  • chaotic background and flutter sawtooth

Torsades de points = turning of points around heart therefore changing amplitude

V-tach - monomorphic, wide complex, fast rhythm

Diltiazem (CCB) can be used instead of beta blocker in asthmatics

AF MX

echo: to assess left ventricular function, atrial size and valve function

Paroxysmal AF: consider antithrombotic
infrequent and/or asymptomatic antiarrhythmics may not be required. Symptomatic start bisoprolol 2.5mg OD and titrate to 10mg if needed (second line or beta blocker contraindicated = flecainide or solatol) . CAD?: amiodarone or dronedarone. poor LVF? amiodarone or non pharma

Persistent AF (longer than 7 days or terminated by cardioversion)

Rate controlled: >65, CAD, w/o CHF, contraindications for antiarrhythmics, unsuitable for cardioversion

rhythm controlled: symptomatic, younger, first time lone af, af secondary to corrected precipitant, CHF

Cardioversion: part of rhythm control . . . should be anticoagulated 4 weeks prior with warfarin . pharmacological with flecainide 2mg/kg iv over 10-30mins with monitoring

Acutre onset and haemodynamically unstable
(chest pain, SOB, hypotension/underperfusion, pulmonary oedema, myocardial ischarmia)
DC cardioverioversion stat

  • if CHF then use digoxin in acute setting if already on beta blocker . . rate limiting CCB contraindicated in excerbation HF

stable and decide to cardiovert? (beneficial in young, non CAD, low risk)

<48hr - heparinise and give DC cardioversion (anticoag not needed after unless CHADVAS score) or amiodarone

>48hrs either anticoag 3 weeks before and 4 weeks after DC conversion or TOE to exclude left atrial appendage (LAA) thrombus then can heparanise and DC cardiovert immediatelly

if previous cadioversion failure should have 4w amiodarone before DC cardioversion

CHA2DV2ASC - determine anticoag strategy:

0- non aspirin no longer recommended

1- consider for males

2 - offer anticoag (NOAC or Warfarin)

HASBLED score if starting warfarin - high risk =>3

Slow

Narrow and wide not as important here

PACE if too slow or unstable

Atropine helps for the first two - maybe 3rd

Idioventricular rhythm has no p waves as only ventricles contracting

stability - American Heart Association, includes systolic blood pressure < 90 mm Hg, altered mental status, cardiac ischemia, or severely decompensated heart failure due to the underlying rhythm.

Thyroid

A

T4 = spark plug of the body

mentaion = brain moving

Hyperthyroidism

Hyperthyroid = thyrotoxicosis = too much T4

weight loss form diarhoea and metabolism

Oligomenorhoea leading to Amenorrhoea

Screen with TSH and confirm with free T4

Exception to decrease TSH is central where TSH drives the T4

Thyroid Storm

Hypertension

IV propanalol

antithyroid drugs ; methimazole or propylthiouracil

dexamethasone -stops T4 conversion to T3

RAIU scan = radioactive iodine uptake = nuclear scintigraphy

. . . goes wherever T4 being MADE

MNG = multinodular goitre

Graves

smoking is a risk factor

TSH receptor antibodies (also anti-TPO antibodies)

RAIU lights up

specific findings = bugg eyes and muddy shins, acropachy (clubbing)

surgery as radioactive iodine will make exo and PM worse

Anti-thyroid drug titration (40mg carbimazole then gradual reduce when euthyroid) 12-18 months

block and replace (40mg carbimazole then add thyroxine when euthyroid) 6-9 months

carbimazole can cause agranulocytosis

Thyroiditis

T4 leaks out there transient hyperthyroid state . . .will heal or die after

painfull = de querveins and painless = hashimotos

RAIU = cold

Riedel’s thyroiditis = rare, dense fibrosis, painless, usually mroe common in women

De qierveoms (subacute) -

reduced iodine uptake in scintography - usually self limiting - NSAIDs for pain

2-6w painful hyperthyroidism >1-3w euthyroid > weeks/months hypothyroidism > structure/fxn back to normal

MNG and toxic adenoma

RAIU will show nodes

factitious and stroma present stroma ovaria = both exogenous . . .. factitious = trying to lose weight

TX

can use same medications for ther conditions but go for surgery/ Radioactive iodine ablation as don’t want lifelong medication

Hypothyroidism

Menorrhagia but can lead to Amenorrhoea

Doesn’t matter how you get it, tx with levothyrxin

TSH up unless its a central problem (rare)

Iatrogenic = Graces Tx

non iatrogenic = MC hashimotos ( TPO abs to confirm)

Myxedemic coma = sever of hypo (give iv corticosteroids to tackle co-existing adrenal insufficiency)

so cold intolerant that becomes hypothermic which leads to hypotension

Tx with warm IVF and warm blankets

give IV T4 and more potent T3 if that does not work.

MX

Levothyroixine = 50-100mcg od (severe/cardiac disease/ elderly start 25mcg and titrate up)

target TSH value 0.5-2.5 mU/l

measure every 8-12 weeks

pregnancy icnrease by 50% as early as 4-6 weeks of pregnancy

REMEMBER in the vast majority of cases:

Low TSH = high T4 = hyperthroidism

High TSH = Low T4 = Hypothyroidism

Infective Endocarditis

A

Dukes Criteria technically not clinical criteria

Definite if:

Two Major (culture and echo)

one major + 3 minor

5 minor

Murmur

The most common valvular abnormality in infective endocarditis is tricuspid regurgitation. Combined with the fact that this man is showing sings of right sided heart failure (peripheral oedema)

Holosystolic Murmur louder on inspiration

RFs

h/o endocarditis (scares perfect place to set up shop)

vascular

Acute limb ischaemia

Splinter haemorages

janeways lesions (painless)

Rhematologic Sx

Roth spots (eyes)

Osler nodes (painful lesion on finger pulp)

Glomerulonephritis

Two main presentations in Practice

Acute

CHF presentation or Bacteraemia presentation

empiric tx and blood culture until nothing

not enough time for Rheum sx to present

Subacute

more insidious

keep doing cultures till you detect something (harder to grow)

no abx at first or won’t culture

TEE for IE (In practice you would probs do TTE first)

Empiric Tx

Depends on pt (what valve and how long), not organism

Vanc & Gent backbone

NICE TX

Native : amoxacillin

Prosphetic : Vanc + low dose gent + rifampicin

Pen al/MRSA/ SEVERE : vanc + low dose gentamicin (acts on biofilms well)

strep - benzylpenicillin

staph- flucloxacillin

Surgery

if risk of embolism or something the abx won’t tx

Prophylaxis (NICE actually recommonds against PPX)

If Bad Valve + mouth/Throat procedure

BV = h/o endo, prosthetic, congenital heart disease

MT - dental procedues/ biopsy of airway + GI tract + gynae obs procedures

AND

if you can’t us vanc then use dapto

If you culture S.Bovis do a colonoscopy (they have colon cancer)

Organisms

S.aureus MC

S.epididimus MC postoperative eg indwelling lines

Strep viridans (pseudotoxic term . . . MC ones are S.mitis and S. Sanguinis) (poor dental hyegine)

Strep bovis - colon cancer

Culture negative;

HACEK: Haemophilus, Actinobacillus, Cardiobacterium, Eikenella, Kingella)

Post Op Fever

A

Fever = inflamation, not neccessarily infection

Wound healing causes fever (closer to surgery the more likely wound healing)

temp >39 is what’s alarming (or sx)

>38 after 48hrs do the fever workup

5 Ws

used to be what infections (not true) now use for prevention framwork

so fever with some sx

atechelitis does not case fever but can lead to collapsed alveoli and pneumonia

incetative spirometry not enough evidence (big breaths should open up alveoli but waliking will open more naturally)

Get cathetar out early to prevent infection

Malignant hyperthermia

AD= autosomal dominant

(ca channels stay open leading to massive sustained contraction using lots of energy and generating lots of heat)

Wound is rest of slide

predicting infxn

different types of wound

clean = does not go near any mucosa

clean contaminated = mucosa but it was deliberate without spillage

contaminated (oopsy or ruptured prior to surgery)

Dirty = dirty source eg fecal contamination, foreign object wound

wash out as things can be hinding in crevices

Nec Fac

any organism but those are most associated.

black = evidence of necrotic tissue under skin

Grey dishwater as serum with lots of dead stuff in it

Bacteraemia
no skin changes to differentiate from Nec Fac

Superficial Skin Infection

usually infection of subcutaneous fat (cellulitis)

usually don’t see alone but with wound dishenence.

Deep Peritoneal Infection

2 kinds.

free fluid is normal after surgery but if not absorbed can develop to abscess

abscess is inflamed by definition as immune system has made it

If leak then spillage is ongoing . .. will be sicker

abscess = focussed peritonitis as its walled off

Always look for these if unresolving ileus.

Athletes commonly present with a sharp or burning pain around the lateral knee joint line. **Plantar Fasciitis (not trauma)** Plantar fasciitis is the most common cause of heel pain seen in adults. The pain is usually worse around the medial calcaneal tuberosity. Management rest the feet where possible wear shoes with good arch support and cushioned heels insoles and heel pads may be helpful **trochanteric bursitis (non trauma)** aka Greater trochanteric pain syndrom MC women 50-70 from repeated movement of the fibroelastic iliotibial band pain over the lateral side of hip/thigh tenderness on palpation of the greater trochanter

Hip Fractures
**CF**: shortened, externally rotated flexed leg **IX**: AP pelvis and lateral xray MX : **Pre-operatively** Analgesia including a fascia iliaca block, stop anticoagulants/anti-platelets & early surgery. **Post operatively** Thromboprophylaxis, early mobilisation Beware of delirium! Garden Classification ( for intracapsular fractures)

Principoles of fracture Mx
**Resuscitate \> Reduce \> Hold \> Rehabilitate** **Reduce** Reduction in the taction of soft tissues (to reduce swelling) of transversing nerves ( to reduce neuropraxia) and reduction of pressures on blood vessels (restoring blood supply). Some use an initial exaggeration of fraction to uncouple distal and proximal fragments can be done open or closed Requires analgesia e.g. local/regional blockade or conscious sedation requires at least two people (one apply reduction force and another counter reduction . . . . often 3rd for casting) **Hold** immonilising fracture consider need of traction where strong muscles pull across facture sites eg femur fractures most commonly simple splints or casts casts non circumferential in first 2 weeks due to risk of compartment syndrome axial instability: casts need to cross both the joint above and below if # able to rotate along axis eg combined tibia/fibula metaphyseal # or radius/ula metaphyseal # weight bear? always let pt know if they can Thromboprophylaxis: common if immobilised and non-weight bearing safety net pt on sx of compartment syndrome. **Rehabilitate** Intensive period of physiotherapy as pts stiff after immobilisation encourage movement of non-immobilised unaffected joints from outset Frailty a significant risk factor so therapists essential to making sure suitable adaptions implemented for their recovery

Might underestimate for HIV, NICE suggest QRISK2 may underestimate CVD risk in the following population groups: people treated for HIV, SLE, antipsychotics, steroids and immunosuppresent drugs Measuring lipid levels A full lipid profile should also be checked (i.e. including triglycerides) before starting a statin. The samples does not need to be fasting. Can feed lipid measurements into QRISK score. Consider familial hyperlipidaemia if very high If \>10% statin indicated (offer period of lifestyle modification first) also offer statin for DM as above and CKD **Other tests** TFTs - can be caused by hypothyroidsim Bloood Glucose: DM can cause Anorexia nervosa can also cause **Secondary prevention** All patients with CVD should be taking a statin in the absence of any contraindication. Atorvastatin 80mg should be offered first-line. Follow-up of people started on statins (asthenia (physical weakness), flatulance, headaches) NICE recommend we follow-up patients at 3 months repeat a full lipid profile if the non-HDL cholesterol has not fallen by at least 40% concordance and lifestyle changes should be discussed with the patient NICE recommend we consider increasing the dose of atorvastatin up to 80mg **Familial Hyperlipidaemia** Ezetimibe inhibits the absorption of cholesterol Bezafibrate reduce serum triglycerides. **Lifestyle modifications** These are in many ways predictable but NICE make a number of specific points: **Cardioprotective diet** total fat intake should be \<= 30% of total energy intake saturated fats should be \<= 7% of total energy intake intake of dietary cholesterol should be \< 300 mg/day saturated fats should be replaced by monounsaturated and polyunsaturated fats where possible replace saturated and monounsaturated fat intake with olive oil, rapeseed oil or spreads based on these oils choose wholegrain varieties of starchy food reduce their intake of sugar and food products containing refined sugars including fructose eat at least 5 portions of fruit and vegetables per day eat at least 2 portions of fish per week, including a portion of oily fish eat at least 4 to 5 portions of unsalted nuts, seeds and legumes per week **Physical activity** each week aim for at least 150 minutes of moderate intensity aerobic activity or 75 minutes of vigorous intensity aerobic activity or a mix of moderate and vigorous aerobic activity do musclestrengthening activities on 2 or more days a week that work all major muscle groups (legs, hips, back, abdomen, chest, shoulders and arms) in line with national guidance for the general population **Weight management** no specific advice is given, overweight patients should be managed in keeping with relevant NICE guidance **Alcohol intake** again no specific advice, other than the general recommendation that males drink no more than 3-4 units/day and females no more than 2-3 units/day **Smoking cessation** smokers should be encouraged to quit

Joint Pain Approach
REMEMBER THESE ARE GENERAL RULES First differentiate by numbers then acuity/ toxicity High acuity/toxicity you admit - low one harder to spot Ser -ve = PAIR Poly = VIRUSSSSS SLEs like big joints. RA likes small joints AP = lower back OA = weight bearing joints (shoulder/hip) or joints with previous trauma/surgery Acute = red hot swollen tender and immobile Reactive = ive got gonorhoea and my joint hurts. Infective = I have gonourhea in my joint The (A)s are for acute toxicity Abs most important to learn from top to bottom
45
Asthma
Not all wheezing asthma but should always consider Ominous = lots of air trapping and not much room for air movement PFTS = spirometry ach agonist = Methacholine Negavite Spirometry does not exclude asthma: ix further with fractional exhaled nitric oxide (FeNO) testing **Tx** Bronchoconstricion with bronchodilators Inflammation with anti-inflammatories Stabalisers can be used for athletic asthma as you can take pre-emptivly (cromolyn/ nedocromil) short course of prednisolone for acute episodes (eg 5day hx of wheeze and cough and already on medicaiton) **Adult Tx** 2- jump in here if Newly-diagnosed asthma with symptoms \>= 3 / week or night-time waking Salmeterol = LABA aka a 'controller' **Child 5-16 tx** The same as adult but stop LRTA at 4 Jump to 2 if Newly-diagnosed asthma with symptoms \>= 3 / week or night-time waking 8 week trial: After 8-weeks stop the ICS and monitor the child's symptoms: if symptoms did not resolve during the trial period, review whether an alternative diagnosis is likely if symptoms resolved then reoccurred within 4 weeks of stopping ICS treatment, restart the ICS at a paediatric low dose as first-line maintenance therapy if symptoms resolved but reoccurred beyond 4 weeks after stopping ICS treatment, repeat the 8‑week trial of a paediatric moderate dose of ICS **Exacerbation** Life threatening: *SpO2 \<92% PEF \<33% best or predicted Silent chest Poor respiratory effort Agitation Altered consciousness Cyanosis* Nebs = Ipratropium (muscarinic antagonist)/ salbutamol PEFR = peak espiratory flow rate ( they should know their best) All patients to receive PO prednisolone Oxygen through non rebreath MDI = metered dose inhalors Rescue medication : Racemic adrenaline neb, subq adrenaline, IV magnesium all used to try and prevent intubation **Grades** 1 - intermitent 2/3/4 = intermittent 2. mild 3. moderate 4. severe Refractory = tx not working **Adult Corticosteroid Doses** \<= 400 micrograms budesonide or equivalent = low dose 400 micrograms - 800 micrograms budesonide or equivalent = moderate dose \> 800 micrograms budesonide or equivalent= high dose. **Paeds Corticosteroid Doses** \<= 200 micrograms budesonide or equivalent = paediatric low dose 200 micrograms - 400 micrograms budesonide or equivalent = paediatric moderate dose \> 400 micrograms budesonide or equivalent= paediatric high dose. **Maintenance and reliever therapy (MART)** a form of combined ICS and LABA treatment in which a single inhaler, containing both ICS and a fast-acting LABA, is used for both daily maintenance therapy and the relief of symptoms as required MART is only available for ICS and LABA combinations in which the LABA has a fast-acting component (for example, formoterol) **Criteria for discharge** been stable on their discharge medication (i.e. no nebulisers or oxygen) for 12–24 hours inhaler technique checked and recorded PEF \>75% of best or predicted

Oesophagitis
**Oesophagitis in general** As you often have to do a biopsy and take a **PIECE** E for GORD and everything else MC presents with odynophagia but sometimes just dysphagia Give some sort of antacid for all as if its not the cause it can make it worse **Pill induced** Gets stuck and inflames surface Non-entric coated NSAIDs notorious for it Pill often not still there but remove if it is Should recover with PPI PPX but taking pills with a whole glass of water adn not when lying down **Infectious** Pretty much anything can cause but remember these four Candida - oral candidasis with oesophagitis symptoms (tx with fluconazol HSV = herpes = painful prodrome, vesicles on erythematous base and ulcers at multiple stages of healing cal or acyclavir CMV - wont see anything HIV - opportunitstic infections and to remind you infectious oesophagitis often in immunosuppressed **Eosinophilic** allergic reaction in oesophagus EGD with \>15eos per high powered field then you trial PPI as GORD often causes . . .. if they were origionally tx for GORD before biopsy then they now get oral aerosolised steroids **Caustic** Kid eg drinking drain cleaner Aduld = suicide attempt Touches all on way down inc larynx OGD to determine severity Low = trial liquid diet and monitor High severity = strictures with necrotic black looking oesophagus Never neutralise pH as it can cause a exothermic reaction and burn again . .. .. or expose again on induced emesis NGT and flush and suck multiple tiems

Spine Examination
**WIPE** **LOOK** pt standing From back: muscle wasting, assymetry, scoliosis of spine, scars, skin changes, hairy patches Frome side: Cervical lordosis, thoracic kyphosis and lumbar lordosis Front: head, shoulders, hands level and no lower limb abnormality Gait: four phases present? normal armswing? symetricle, smooth, stable and good speed? **MOVE**  Assess lumbar flexion and extension by placing two or three fingers over the lumbar spine. Ask the patient to bend to touch their toes. Your fingers should move apart during flexion and back together during extension.  lateral flexion: run leg down side of legs- extent/quality/pain?  Cervical spine: lateral flexion (ear to soulder), rotation, extention (back and forwards). Extent/quality/pain?  Thoracic Rotation: sit, cross arms and rotate. extent/quality/pain?  With the patient lying as flat as possible, perform straight leg raising (see Figure 20). Dorsiflexion of the foot with the leg raised may exacerbate the pain from a nerve root entrapment or irritation such as that caused by a prolapsed intervertebral disc.  Assess limb reflexes (upper and lower) and dorsiflexion of the big toe. **FEEL** lying face down (sitting if this is not possible) feel spinal process for tenderness, pain, swelling and stiffness (and steps indicating possible subluxation) feel paraspinal mucles for tenderness/spasm Compress sacroiliac joint for tenderness **SPECIAL TESTS** Dermatomes, Myotomes and reflexes of the upper and lower limbs Femoral Nerve Stretch: face down, flex at knee, extend hip while compresses SI joint. reproduce anterior thigh pain = maybe compression of upper lumbar spinal nerve routes SLR: lift until symptoms reproduced, then lower a for degrees, then passive dorsiflexion = maybe compression of lower lumbar pinal nerve route or sciatic nerve SI joint Distraction test: +ve if reproduces pain Hip to shoulder test (assess SI joint also) - flex knee up to oppostie shoulder . .+ve test reproduces pain Hoffman's Sign (for UMN lesion eg Cervical cord compression): tap middle finger, +ve if involuntary contraction of thumb and index finger flexures Can also examine pulses if indicated. **Complete** Thank pt, ask to redress and summarise **Summary** “Today I examined Mr Smith, a 32-year-old male. On general inspection, the patient appeared comfortable at rest, with no stigmata of musculoskeletal disease. There were no objects or medical equipment around the bed of relevance.” "General inspection of the spine revealed normal spinal curveture, no scars or muscle wasting and symetrical alignment of back and joits" "No tenderness, swelling, stiffness was noted on palpating the spinous processess and no tenderness or spasms on palpation of paraspinal muscles. No tenderness of Sacroiliact joint was ilicited" “Movement ofcervical, thoracic and lumbar spine was normal.” “In summary, these findings are consistent with a normal examination of the spine.” “For completeness, I would like to perform an upper and lower limb neurological examination, examine hips and shoulder joints and consider imaging of the spine.”

A ‘normal’ PaCO2 in a hypoxic asthmatic patient: a sign they are tiring and need ITU intervention. A ‘very low’ PaO2 in a patient who looks completely well, is not short of breath and has normal O2 saturations: this is likely a venous sample.

Combined with the fact that this man is showing sings of right sided heart failure (peripheral oedema) Holosystolic murmur louder during inspiratio **Replacement for all 1st four but can medically manage by afterload reduction and diuresis** **Patterns of the 4** Left diastolic/ right systolic up is heart apex+aortic dilation/ down is base +VD Insufficiency = more acute/ stenotic = more insidius **Extra** Venous hum is a benign murmur heard in children and sounds like a continuous blowing noise heard below the clavicles A pansystolic murmur is associated with mitral regurgitation. An ejection systolic murmur is associated with aortic stenosis. A continuous 'machinery' murmur is associated with a patent ductus arteriosus. A late diastolic murmur is associated with mitral stenosis.

Cardiovascular Examination
WIPE Postion/Exposure General Inspection General Examination Chext examination: Inspection Palpation Auscultation Special Manouvres Additional Examination Bedside Investigations Proffesionalism **Presentation** Name and Age 5 things of general inspection/ exam: warm peripheries, pulse rate was xxx, regular rhythm and normal volume, CRT \<2s, non cyanotic and no appreviable JVP On Inspection of the chest there were not notable scars On Palpation . . . . On auscultation . . .. There was no eveidence of peripheral oedema My THREE top differentials are: For further Ix I would like . .. **WIPE** **Correct position and adequate exposure** **General Inspection** **General Examination (vital signs)** Hands and anils radial pulse BP Eyes Face/mouth Neck Carotid pulse **Inspection** **Palapation** Apex Beat Heaves and thrills Auscultation Mitral Aortic Tricuspid Pulmonary **Special Manouvres** Mitral stenosis Aortic Regurgitation Mitral regurgitation Aortic stenosis **Additional Examination** Lung bases periperal pulses Peripheral odema Abdominal Examination **Bedside Investication** **Professionalism** Look, point and touch everything you exam eg scars/marks Ankle oedema Hold for 10s, look at face to see if painful, then check how pitted Anaemia Remove glasses and pulldown eyelids yourself. get patint to look dows and check for icterus JVP 'No appreciatable JVP' **Extra** Collapsing pulse is a feature of aortic regurgitation, PDA, and hyperdynamic states (anaemia, thyrotoxicosis, fever, exercise/pregnancy) A pansystolic murmur is associated with mitral regurgitation. An ejection systolic murmur is associated with aortic stenosis. A continuous 'machinery' murmur is associated with a patent ductus arteriosus. A late diastolic murmur is associated with mitral stenosis.
