Q

what investigations would you order in suspected heart failure?

A

BNP (serum B type natriuretic peptides) and NTproBNP (N-terminal-pro-BNP) - if raised, refer to cardiology for review.
ECG (if ECG and BNP normal, NICE says it’s probs not heart failure)
might do an echo - can identify cause.
also - CXR, lung function tests if trying to exclude respiratory cause, bloods (FBC, U&E, creatinine, eGFR, TFTs, BM/HbA1c) - these are to test for exacerbating factors and things you can treat!

Q

how does furosemide work? side effects?

A

laymans terms = works on kidneys to help you get rid of excess fluid, which can make symptoms better

acts on ascending limb of loop of Henle to inhibit the Na/K/2Cl co transporter

SEs - hypokalaemia, renal impairment.

Q

how do ACE inhibitors work in heart failure? side effects?

A

angiotensin-converting enzyme inhibitors - ramipril, lisinopril.

first line for chronic heart failure - improves symptoms and prognosis
laymans - reduces the strain on your heart by lowering your blood pressure, makes it easier for heart to work.

block action of ACE, preventing conversion of angiotensin I to angiotensin II - reduces peripheral vascular resistance, so lowers BP (and afterload!)

SEs - hypotension (esp first dose), dry cough (due to excess bradykinin), hyperkalaemia, renal impairment

be aware of first-dose hypotension, especially if starting on loop diuretic at the same time!

Q

how do ACE inhibitors work in hypertension? side effects?

A

angiotensin-converting enzyme inhibitors - ramipril, lisinopril.

first line if <55yrs and not afro-carribbean

laymans - improves blood pressure by encouraging veins and arteries around your body to relax a bit, reduces strain on your heart.

block action of ACE, preventing conversion of angiotensin I to angiotensin II - reduces peripheral vascular resistance, so lowers BP.

SEs - hypotension (esp first dose), dry cough (due to excess bradykinin), hyperkalaemia, renal impairment

Q

how do beta blockers work in heart failure? side effects?

A

e.g. bisoprolol, atenolol

first line option - improves prognosis

via beta1-adrenoreceptors (in heart, beta2 ones are in vessels and airways) these drugs reduce force of contraction and speed of conduction in heart - ‘protects’ heart from effects of chronic sympathetic stimulation.

start low, go slow - might initially impair cardiac function, so don’t just whack the dose straight up - titrate up every 2+ weeks.

SEs - fatigue, cold extremities, headache, GI upset, erectile dysfunction.
CONTRA-INDICATED IN ASTHMA

Q

how does spironolactone work in heart failure? what kind of drug is it? side effects?

A

used if at least moderate severity, or heart failure arising within 1 month of an MI, generally as addition to beta blocker and ACEi/ARB.

it’s an aldosterone antagonist.
inhibits action of aldosterone by competitively binding to the aldosterone receptor - increases sodium and water excretion, and potassium retention (risk of hyperkalaemia when combined with ACEi).

SEs - hyperkalaemia, gynaecomastia, erectile dysfunction

Q

how do ACE inhibitors work as antihypertensives? important side effects?

A

reduce risk of stroke, MI and death from CVD.

block action of ACE to prevent conversion of angiotensin I to angiotensin II. angiotensin II would normally be causing vasoconstriction, so blocking it means peripheral vascular resistance drops.

SEs - dry cough!! due to increased levels of bradykinin, which is usually inactivated by ACE. also first dose hypotension, hyperkalaemia, renal failure.

Q

how do CCBs work as antihypertensives? important side effects?

A

reduce calcium entry into vascular and cardiac cells - causing relaxation and vasodilation in arterial smooth muscle - lowers BP

amlodipine/nifedipine (dihydropyridines) are selective-ish for vessels, while diltiazem/verapamil (non-dihydropyradines) are more cardio-selective.

SEs (of dihydropyridines) = ankle swelling, flushing, headache and palpitations.

Q

how do thiazides/thiazide-like diuretics work as antihypertensives? important side effects?

A

e.g. bendroflumethiazide (no longer NICE recommended though), indapamide

inhibit Na/Cl co-transporter in distal convoluted tubule of nephron - prevents reabsorption of sodium and so more water excreted.

tell patient - offering you a ‘water tablet’ for your high BP, will also help with leg swelling if they have it - ask about difficulty getting to toilet on time!

Q

give an example of an alpha-blocker. what common chronic condition are they used fourth line?

A

used in resistant hypertension
(also first line option for BPH)

act on alpha1 adrenoceptors, which are mostly found in smooth muscle and urinary tract. so block those to induce relaxation, can drop BP.

SE - hypotension! esp. postural. dizziness and syncope.

explain Gillick competence

A

a competent child is one who can understand the nature, purpose and possible competence of a proposed procedure + the consequences of not undergoing the procedure.

competent child (<16) can consent to treatment, but if they refuse they can be overruled by parents/court.

if not competent - only someone with parental responsibility can authorise/refuse
UNLESS it’s an emergency - can provide any medical treatment, limited to what is necessary for saving life

Q

how would you explain the importance of vaccination to a mother concerned about their safety and considering not allowing her child to be vaccinated? include an explanation of herd immunity

A
  • immunisations have caused massive improvements in health since they were introduced
  • their quick, safe and effective
  • child’s body will then be able to fight off diseases better - there’s a greater risk of them being exposed to harm if they aren’t vaccinated (due to risk of catching, a being very ill from, the illness)

herd immunity = when a large portion of population have been vaccinated, everyone benefits from herd immmunity - important that all healthy children are vaccinated, as there’s a proportion who can’t due to immune problems - herd immunity helps to protect them. it also prevents large outbreaks, and can lead to virus eradication.

Q

explain the ‘UPSSI’ acronym for remembering what to do re <16yo requesting contraception - Fraser criteria

A

U - understands advice and risks involved
P - parents - can you persuade/encourage them to speak to parents
S - suffer - without the contraception, their physical/mental health is likely to suffer
S - sex - still gonna have sex either way!
I - interests - it’s in the best interests of the patient to have the contraception without parental consent

if under 25 - offer chlamydia screening

138
Q

what types of contraception are ideal for use in teenagers/under 16s?

A

CONDOMS - high failure rate but advise essential for preventing STIs!!!! remember, <25yrs = chlamydia screening

LARC - suggest use in combination with condom (for STI cover) - implant/IUCD/IUS - injection if needed, but raises osteoporosis risk (defs don’t use for >2 yrs)

COCP/POP - suitable method, but compliance issues - relatively high failure rate. POP only really used if LARCs not wanted and COCP CI’ed due to menstrual irregularity.

later - wandering, disorientation, apathy, psychiatric symptoms, behaviour problems, altered eating habits, incontinence

144
Q

what are the pharmaceutical options for management of alzheimers disease?

A

acetylcholinesterase inhibitors - donepezil, galatamine, rivastigmine
these slow progression, but don’t stop it. only work for some people. can have GI side effects.
memantine - NMDA antagonist

145
Q

what are some non-pharmaceutical management options for alzheimer’s disease?

what is vascular dementia? what are the main subtypes?

A
  • cognitive impairment caused by ischaemia or haemorrhage, secondary to cerebrovascular disease.

main subtypes = stroke-related, subcortical, mixed dementia (e.g. vascular dementia and alzheimers)

147
Q

risk factors for vascular dementia?

A
  • hx of stroke/TIA
  • AF
  • hypertension
  • DM
  • hyperlipidaemia
  • smoking
  • obesity
  • CHD
  • FHx stroke/CVD
148
Q

how does vascular dementia present and progress?

A

progression may be sudden or gradual but is classically stepwise
imaging shows cerebrovascular disease
features indicating possible vascular cause:
- focal neurology
- difficulty w/ attention and concentration
- seizures
- depression ± anxiety
- early present of disturbance in gait/falls
- bladder symptoms

149
Q

brief explanation of treatment and prognosis of vascular dementia

A
  • no pharmacological options - AChE inhibitors and NMDA antagonists should NOT be used for anything other than Alzheimer’s dementia.

occasionally donepezil used

prognosis - bad - life expectancy 3-5yrs

150
Q

what is dementia with Lewy bodies?

A

‘eosinophillic intracytoplasmic neuronal inclusion bodies’ (Lewy bodies) in the brainstem and neocortex

151
Q

how does Lewy body dementia present?

A
  • dementia symptoms - memory loss, decline in problem solving etc
  • characteristic fluctuation in levels of awareness and attention
  • signs of mild Parkinsonism
  • visual hallucinations
  • sleep disorders
  • fainting spells - “drop attacks”
152
Q

brief explanation of treatment and prognosis of Lewy body dementia

A
  • avoid anti-Parkinsonian treatment
  • cholinesterase inhibitors e.g. rivastigmine at >6mg/day can treat cognitive decline according to NICE when I did GP - disputed in Cochrane review - maybe check this??

prognosis = 5-8y survival from onset

153
Q

what is frontotemporal dementia?

A

atrophy of fontal and temporal lobes - compared to diffuse atrophy in Alzheimer’s

154
Q

what are the 3 main syndromes that frontotemporal dementia presents with?

A

1) behavioural variant - loss of inhibition, inappropriate social behaviour, loss of empathy etc - most common
2) semantic dementia - loss of vocab with fluency of speech maintained, word finding difficulty, loss of facial recognition, memory comparatively well-preserved
3) progressive non-fluent aphasia - slow, hesitant speech, loss of literacy, difficulty with complex sentences

155
Q

what support services are in place for people with dementia?

A

care and support plan / support plan for carers - gets put in place after health and social needs assessment
Admiral nurses - dementia experts
Alzheimer’s society/other charity sector things - memory cafes, befriending, singing for the brain etc
Community care - home care / personal assistants, day hospitals/services
Memory clinic - does CT head, extensive questionnaire’s/assessments, treatment, take detailed collateral history

156
Q

what is an IMCA?

A

independent mental capacity advocate

service that provides advocacy for people deemed lacking in capacity - they know lows about the Mental Capacity Act, human rights, ethics/law stuff etc, spend time with patient trying to understand their wishes.
used when making decisions about:
- long-term care move;
• serious medical treatment;
• adult protection procedures; or
• a care review.
appointed when someone has no nominated friend/family to help make these decisions, or anyone with power of Attorney (personal and welfare) or a personal welfare Deputy

157
Q

what does it mean to make a ‘best interests decision’?

A
  • everything that’s done on behalf of someone who lacks capacity must be in that persons best interests
  • the person is able to put wishes in a written statement, and these must be taken into account (even if lacks capacity)
  • carers/family have right to be consulted
158
Q

what are the five key principles of the mental capacity act?

A

1) every adult has the right to make decisions and must be assumed to have capacity until proved otherwise
2) every adult must be given all possible help and support to make and communicate decisions before being consider to have lost capacity
3) making an unwise decision doesn’t mean they lack capacity
4) anything done or decision made on behalf of them must be in their best interests
5) it must also be the least restrictive of their basic rights and freedoms

159
Q

what does “lasting power of attorney” mean?

A

legal document an individual might have drawn up to appoint someone else to make decisions for them - can be written any time whilst the person has capacity - no legal standing till registered with Office of the Public Guardian.
two types - property and affairs vs personal welfare.
personal welfare is the healthcare one, only works when registered and the individual lacks capacity. Attorney can only make decisions about life-sustaining treatment if the LPA specifies that.

160
Q

give some basics of how advanced decisions work

A
  • these are statements about wishes regarding medical treatment in case individual become incapable later - legally binding, don’t have to be written except for refusal of life-sustaining treatment
  • if refusing life-sustaining treatment, must be: written, specific (e.g. CRP), signed by individual and a witness
  • respect any refusal of treatment as long as clearly applicable to given circumstances!
  • cannot include decisions about what patient would like, only refusals - can’t include directions to prematurely end life
  • if a Dr is unwilling to carry through an advance directive, should pass over care to another doctor who is
  • BMA recommends don’t withhold ‘basic care’ (e.g. symptom control) even in face of directive specifying no treatment
  • if no formal advance decision - take patients wishes into consideration where known
161
Q

what is Deprivation of Liberties Safeguarding (DoLS)?

A

used in care homes and hospitals, written document, aims to make sure people can be given the care they need in the least restrictive regimes possible.

‘deprivation of liberty’ is where someone is under continuous supervision and control, is not free to leave, and they lack capacity to consent to these arrangements.

DoLS helps prevent arbitrary DoL, allows patients the right to challenge unlawful detention

163
Q

give some examples of deprivations of liberty that might be placed on an individual with dementia

A

deciding on the person’s routine, stopping them from walking about at night, or preventing them from leaving.

anything that restricts someone/makes decisions for them

164
Q

define deprivation of liberty

A

‘The person is under continuous supervision and control and is not free to leave, and the person lacks capacity to consent to these arrangements.’

165
Q

what are the three key elements of the DoLS?

A
  • to provide the person with a representative – a person who is given certain rights and who should look out for and monitor the person receiving care
  • to give the person (or their representative) the right to challenge a deprivation of liberty through the Court of Protection
  • to provide a mechanism for a deprivation of liberty to be reviewed and monitored regularly
166
Q

who orders a DoLS assessment? who performs?

A

care home/hospital requests assessment/authorisation from local authority if think person is/will be deprived of liberties
Two people do assessment - best interests assessor, mental health assessor - appointed by local authority, need experience/trained
best interests assessor = qualified social worker, nurse, occupational therapist or chartered psychologist - must not know patient.
mental health assessor = doctor capable of determining if has ‘mental illness’ and impact of DoL on that

167
Q

what 6 things are checked for in a DoLS assessment?

A

Age – Is the person aged 18 years or over?
Mental health – Does the person have a ‘mental disorder’?
Mental capacity – Does the person lack ‘capacity’ (the ability) to make their own decisions about treatment or care in the place that is applying for the authorisation?
Best interests – Is a deprivation of liberty taking place? If so, is it:
– in the person’s best interests?
– needed to keep the person safe from harm?
– a reasonable response to the likelihood of the person suffering harm (including whether there are any less restrictive options and if they are more appropriate)?
Eligibility – Is the person already liable to detention under the Mental Health Act 1983, or would they meet the requirements for detention under this Act?
No refusals – Does the authorisation contradict or conflict with any advance decision the person has made refusing treatment, or with any decisions made by, for example, a court-appointed deputy or someone with Lasting power of attorney?

Has to meet all 6 to be approved

168
Q

how long can a DoLS last?

A

A DoLS authorisation should last for as little time as possible, and only up to a maximum of 12 months. Each individual DoLS authorisation will state the date it lasts until. However, during this time both the care provider and local authority should:

make regular checks to see if the authorisation is still needed
remove the authorisation when it is no longer needed
provide the person’s representative with information about their care and treatment.

169
Q

define food poisoning. what actions should be taken if there’s an outbreak?

Q

what screening questions do NICE recommend asking patients to detect symptoms of depression?

A

During the last month, have you often been bothered by:
feeling down, depressed or hopeless?
having little interest or pleasure in doing things?

174
Q

what options do NICE recommend for initial management of a patient presenting with persistent subthreshold depressive symptoms or mild-moderate depression?

A

sleep hygiene advice
active monitoring (if you think they’ll recover without other intervention, arrange to see in 2 weeks and re-assess)
low-intensity psychosocial interventions e.g. online/guided self-help CBT, group exercise programme
group-based CBT (if decline self-help style CBT)
typically - DON’T use antidepressants, but consider if past history of depression or no response to the above

175
Q

what options do NICE recommend for management or a patient with persistent subthreshold depressive symptoms or mild-moderate depression and no response to initial treatment options? same options used for presenting with moderate-severe depression.

A

anti-depressant (usually SSRI)

high-intensity psychological intervention e.g. CBT, IPT

if moderate/severe depression - provide combination of the above

176
Q

if a patient presents with depression to GP, what are the first things you should do?

A
  • assess severity, comprehensive assessment
  • consider degree of functional impairment, duration of episode
  • assess past history
  • always ask directly about suicidal ideation!
177
Q

when would you consider starting antidepressant treatment if a patient has mild-moderate depression?

A

NOT used typically, only use if:
past history of moderate/severe depression
symptoms persist after other interventions

178
Q

outline the key points to know about antidepressant treatment from the NICE guidelines

A

start with SSRI normally - citalopram, sertraline (not in older people), fluoxetine, paroxetine
warn patients of SEs and importance of continuation, discuss gradual development of full antidepressant effect and the need to continue beyond remission
monitoring - see at 2 weeks, then every 2-4 weeks for first 3 months, then longer intervals.

initial lack of response at 3-4 - check compliance, increase dose if no SEs, switch drug - different SSRI, or try TCA/MAOI/venfalaxine - may be less well tolerated.

REFER if need to start combining/augmenting

179
Q

if a patient’s mood improves and you feel they’re in remission from depression, when do you stop anti-depressant treatment?

A

encourage them to keep taking it for at least 6 months - this reduces risk of relapse.
taper doses down before stopping - including taking lowest dose every other day etc.

180
Q

what screening tools are available for assessing depression?

A

PHQ-9 is the classic - should also do GAD-7 (anxiety version) at the same time.
edinburgh PND questionnaire - done by health visitors for all postnatal women.
HADS = hospital anxiety and depression scale, can be used in primary care setting.

Also alcohol ones to be aware of - CAGE, AUDIT, SADQ

181
Q

when should antidepressants be started?

A

Consider for:
Patients with moderate/ severe depression ± psychological therapy
Dysthymia (subthreshold depressive symptoms lasting > 2y)
Mild depression if other treatment strategies have failed

182
Q

what should you tell the patient before starting antidepressants?

A
  • The reasons for prescribing
  • Timescale of action— unlikely to have any effect for 2wk; effects build up to maximum effect at 4– 6wk, and
  • Likely side effects including possible exacerbation of anxiety in the first 2wk of treatment
183
Q

what are some common side effects of SSRIs?

A

GI upset is the most common
appetite and weight disturbance (loss or gain)
hypersensitivity reactions e.g. rash
initial increase in anxiety and suicidal ideation
can lower seizure threshold
prolong QT interval
can increase risk of bleeding

184
Q

what is serotonin syndrome?

A

  • old/young
  • malnourished
190
Q

outline some measures to prevent spread of TB

A
  • if diagnosed in GP clinic - leave via back door, consider home visits/telephone consultations to avoid spread in waiting room, or have TB clinics (this is all if GP practice is high risk area)
  • BCG vaccine for at risk groups
  • main thing is just identifying and treating adequately
  • within households - adequate ventilation, educate on cough etiquette, hand washing, avoid public transport/crowded places, sleep separately
191
Q

what investigations would you order if you suspected a patient had TB?

A

CXR
Sputum samples for culture (state on the form that you are looking for acid-fast bacilli)
Tuberculin test + ve (may be − ve if immunocompromised) If diagnosis is confirmed, refer for treatment and contact tracing.

192
Q

how is TB treated?

A

RIPE!
2 months on Rifampicin, Isoniazid, Pyrazinamide, Ethambutol
then further 4 months of just isoniazid and rifampicin

193
Q

what are the main side effects of the drugs used to treat TB?

A

Rifampicin - raised LFTs, low platelets, ORANGE WEE, inactivation of Pill, flu symptoms
Isoniazid - can get neuropathy - switch to pyridoxine if so
Pyrazinamide - hepatitis, arthralgia (don’t give if they have gout)
Ethambutol - optic neuritis (first symp. is loss of colour vision)

194
Q

briefly explain ABG interpretation

not really GP but needed to do it at some point

A

PaO2 - want this >10 if healthy and room air. if on O2, should be well above 10. <10 = hypoxaemic, <8 =severely hypoxaemic.
Type 1 resp failure = hypoxaemic but normal CO2
Type 2 resp failure = hypoxaemic but high CO2

pH <7.35 = acidotic, >7.45 = alkalotic
if pH change is respiratory driven - abnormal CO2
if metabolically driven - abnormal HCO3
HCO3 should be 22-26

Base excess > +2 indicates metabolic alkalosis or compensated respiratory acidosis
< -2 indicates metabolic acidosis or compensated respiratory alkalosis

195
Q

give some causes of respiratory acidosis

A

(pH low, CO2 high)
Respiratory depression (e.g. opiates)
Guillain-Barre – paralysis leads to an inability to adequately ventilate
Asthma
Chronic obstructive pulmonary disease (COPD)
Iatrogenic (incorrect mechanical ventilation settings)

196
Q

give some causes of respiratory alkalosis

A

(pH high, CO2 low)
Anxiety – often referred to as a panic attack
Pain – causing an increased respiratory rate
Hypoxia – resulting in increased alveolar ventilation in an attempt to compensate
Pulmonary embolism
Pneumothorax
Iatrogenic (excessive mechanical ventilation)

197
Q

give some causes of angina

A

usually - coronary artery disease

Rarer - HOCM, valve disease, hypoperfusion during arrhythmia, arteritis, anaemia, or thyrotoxicosis.

198
Q

how does angina present?

A

episodic central-crushing or band-like chest pain that may radiate to jaw/neck and/or one or both arms

precipitated by exertion, cold, emotion, and/or heavy meals - stops with rest or GTN spray

associated with palpitations, sweating, nausea, and/ or breathlessness during attacks
has risk factors - smoking, FHx, hx of other vascular disease, peripheral vascular disease

199
Q

what investigations would you order for a patient presenting for the first time with angina?

A

Bloods - FBC, fasting lipid profile, fasting blood glucose. Consider checking ESR (to exclude arteritis) and TFTs if clinical suspicion of thyrotoxicosis

ECG - for arrhythmias, presence of heart block, previous MI, myocardial hypertrophy, and/or ischaemia
ECG doesn’t rule out coronary artery disease, but identifies those at bigger risk of future MI etc

200
Q

how would you manage a patient with stable angina?

A

general advice - avoid heavy manual labour, might need to inform DVLA, stop smoking/modify other RFs where poss
cardiac rehab
PRN drugs - GTN spray (1-2 puffs in response to pain or before exertion)
regular meds - beta blockers or CCB first line, then long acting nitrates (e.g. ivabradine, nicorandil)
secondary prevention - aspirin, statins, ACEi - give to all with angina

201
Q

when might you admit/refer a patient with angina?

A

Admit: unstable angina/rapidly progressive symptoms
Urgent referral: aortic stenosis with angina, angina following MI, abnormal ECG at diagnosis
Routine referral: angina not controlled by medication with two drugs, if diagnosis is in doubt, strong family history, other factors, e.g. occupation affected

202
Q

what is unstable angina? how should you manage it?

A

angina pain occurring at rest, in the night, or which is rapidly worsening in frequency/severity etc

do urgent referrral to cardiology

203
Q

what surgical options are there in the management of angina?

A

PCI/CABG - consider if not responding after trialling 2 drugs

204
Q

what is Prinzmetal angina?

A

occurs with coronary artery spasm, rather than on exertion
ECG will show ST elevation - cardiology referral to exclude MI and atherosclerotic angina.
GTN spray will offer immediate release always, CCBs used to prevent attacks.

205
Q

what are the classic ECG features seen in AF?

A

rapid irregularly irregular narrow QRS complex tachycardia with absence of P-waves.
risk of embolic stroke.

206
Q

give some causes of AF

A
No cause (isolated AF) (12%)
Coronary heart disease
hypertension (especially if LVH)
Cardiomyopathy
Valvular heart disease (especially mitral valve disease)
207
Q

give some factors that can precipitate acute AF

A
acute infection
high alcohol intake
surgery
MI
electrocution
PE
hyperthyroidism
208
Q

how does AF present?

A

typically detected as part of testing for other reasons, being asymptomatic
can cause - palpitations, chest pain, syncope, stroke/TIA, fatigue, dyspnoea

209
Q

how would you investigate a patient with AF?

A

Routine investigations - resting ECG, CXR, Bloods - TFTs, FBC, U&E

further investigations - ambulatory ECG or cardiac memo (measures ECG trace when triggered by patient e.g. to see if symptoms are due to arrhythmia) if paroxysmal AF.
echo if < 50y or murmur/ heart failure detected
consider exercise tolerance test if exercise-related

210
Q

what are the aims/principles of managing AF?

A

to relieve symptoms (e.g. palpitations, fatigue), maintain cardiac function and prevention thromboembolism and stroke risk

if infrequent paroxysmal AF can consider no drugs/’pill-in-pocket’ approach but if chronic or frequent paroxysms need to think about continuous treatment/anticoagulation

211
Q

what would an ECG trace show in a patient with atrial flutter?

A

regular, sawtooth baseline at rate of 300bpm, with a narrow QRS complex tachycardia superimposed at a rate of 150bpm or 100bpm.

managed similar to AF

212
Q

what is the ‘pill-in-the-pocket’ approach to managing AF?

A

self-medication with PRN beta blocker (e.g .atenolol 50-100mg)

213
Q

describe the medical management of AF (controlling the actual AF rather than anticoagulation management)

A

either rate or rhythm control
rhythm control = electrical/chemical cardioversion to sinus rhythm - used if - associated heart failure, new onset AF, atrial flutter suitable for ablation, AF secondary to a treated/corrected precipitant, rate control not successful

rate control - with beta blocked (e.g. atenolol, bisoprolol) or rate-limiting calcium channel locker (e.g. diltiazem). can also use digoxin (but getting into specialist areas here)

214
Q

how do beta blockers work to manage AF? any side effects to warn patient of?

A

drug that slows how fast your heart goes - prolongs refractory period of the AV node.
SEs - fatigue, cold extremities, headache, GI upset, sleep disturbance, erectile dysfunction
CI in asthma!!!!!!!! can cause bronchospasm as they block the beta 2 adenoreceptors in the airways

215
Q

how do CCBs work to manage AF? any side effects to warn patient of?

A

diltiazem and verapamil are the ones used for this (cardioselective)
they suppress cardiac conduction across the AV node, slowing ventricular rate.
SEs - ankle swelling, flushing, headache, palpitations, constipation (verapamil), bradycardia, heart block.

DON’T prescribe with beta blockers - can cause heart failure/block

216
Q

what is the CHA2DS2-VASC score? what are the components?

A

score used to assess risk of stroke in AF patients to decide whether oral anticoagulants are needed.
Get points for the following:

Congestive heart failure
Hypertension
Age: ≥ 75 (2 pts) or 65-74 (1pt)
Diabetes mellitus
Stroke/TIA/thrombo-embolism (2 pts)
Vascular disease
Sex - Female

score of 1 = consider anticoagulating if male
score 2+ for female to consider anticoagulating
target INR = 2-3

217
Q

what is the HASBLED score?

A

used to weigh benefits of anticoagulating against risk of bleeding.
one point for each of:
Hypertension - uncontrolled, > 160 mmHg systolic
Abnormal liver function
Abnormal renal function
Stroke

Bleeding
Labile INRs
Elderly (Age >65)
Drugs/alcohol

score 3+ means consider carefully whether need to anticoagulate

218
Q

what drugs are used for anticoagulation of a patient with AF to prevent stroke?

A

lots of people on warfarin for this (target INR 2-3) - NICE now says to use NOACs only: apixaban, dabigatran etexilate, rivaroxaban or a vitamin K antagonist.

219
Q

when would you offer rate vs rhythm control to someone with AF?

A

Offer rate control as first-line to people with AF, except in people:
whose AF has a reversible cause
who have heart failure thought to be primarily caused by AF
with new-onset AF
with atrial flutter whose condition is considered suitable for an ablation strategy to restore sinus rhythm
for whom a rhythm control strategy would be more suitable based on clinical judgement.

220
Q

what does NICE say about how to assess if people are eligible for medications etc as part of primary prevention of heart disease? what should they receive?

A

Use the QRISK2 scoring system.
decide between statins and lifestyle adjustments only - depends on overall risk, willingness to change etc.

offer atorvastatin 20mg OD to anyone with 10yr CVD risk >10% as determined by Q Risk

if dealing with secondary prevention (e.g. after MI) - always give statin - usually 80mg atorvastatin

221
Q

you are assessing a patient to decide whether to offer statins as part of a primary prevention strategy for CVD - his 10yr risk is 11% - what lifestyle advice should you give before starting the statin?

A

stick to alcohol recommendations
reduce intake of (saturated) fatty foods - eat more mono-unsaturated fats e.g. olive oil
reduce sugar intake, get 5 a day, 2 portions fish per week, 4-5 portions unsalted nuts/seeds/legumes per week
150 mins of moderate intensity aerobic exercise per week, + 2 days of muscle strengthening exercises
STOP smoking
maintain normal BMI

222
Q

how do statins work? any side effects to warn patients about?

A

reduce serum cholesterol levels - given to everyone with a 10 yr CVD risk of >10% (some places say 20% but think it’s been lowered to 10)
inhibit 3-hydroxy-3-methyl-glutaryl coenzyme A (HMG CoA reductase) - enzyme that makes cholesterol. this decreases cholesterol production in liver, and increases clearance of LDL-cholesterol from blood. also reduce triglycerides and slightly increase HDL levels - slows atherosclerotic process and poss even reverses

SEs - headache and GI upset most common. but can affect muscles - aches, myopathy or rhabdomyolysis

223
Q

give some causes of obesity

A

Physical inactivity
Smoking cessation— mean weight ↑ 3– 4kg
Cultural factors
Low education
Polygenic genetic predisposition - around 1 in 3 obese people - more prone to obesity again after successful dieting
Childbirth— especially if not breastfeeding
Drugs— steroids, antipsychotics (e.g. olanzapine), contraceptives (especially depo-injections), sulfonylureas, insulin
Endocrine causes (rare) - hypothyroidism, Cushing’s syndrome, PCOS
Ongoing binge eating disorder

224
Q

what are the management options for obesity?

A

DIET AND EXERCISE - target weight loss of 1-2lbs per week, equivalent to calorie deficit of 600kcal/day (decrease consumption and increase expenditure)

drugs - orlistat, decreases fat consumption, trial if >3m consistent weight loss effort has failed

surgery - adjustable gastric band most common. use if BMI >40 and all non-surgical options have failed. Complications: band slippage/ damage; gastric erosion, pouch dilatation; infection; malabsorption.

225
Q

describe the medical options to aid smoking cessation

A

NRT e.g. patches, gum, sprays - swap out for cigarettes, use for 8 weeks then stop completely
bupropion - an atypical antidepressant shown to aid smoking cessation. don’t give if seizure prone.
varenicline - alpha-4 beta-2 (α4β2) nicotinic acetylcholine receptor partial agonist - both blocks and stimulates the receptor - both reduces nicotine cravings, and reduces pleasure effect of smoking.

226
Q

what is osteoporosis?

A

reduced bone mass and deterioration of bone architecture - usually described as low bone density. means bones are more fragile and prone to fracture.

fracture risk assessed using FRAX (can calculate with or without BMD) or QFracture (based on UK pop, doesn’t use BMD)

227
Q

give some causes of osteoporosis

A

Endocrine - hypogonadism (e.g. premature menopause, anorexia, androgen blockade, taking aromatase inhibitors), hyperthyroidism, hyperparathyroidism, hyperprolactinaemia, Cushing’s disease, type 1 DM

GI - coeliac disease or other causes of malabsorption, inflammatory bowel disease, chronic liver disease, chronic pancreatitis

Rheumatological - RA, other inflammatory arthropathies

Other - immobility, multiple myeloma, haemoglobinopathy, systemic mastocytosis, CF, COPD, CKD, homocystinuria

STEROIDS

228
Q

define ‘fragility fracture’. what types are common?

A

Fracture sustained falling from ≤ standing height— includes vertebral collapse (may not be as a result of a fall).

commonly - hip, wrist (Colle’s #), osteoporotic vertebral collapse (get pain, reduced height, kyphosis)

229
Q

give some risk factors for osteoporosis

A

Female sex.
Low body mass (<19 kg/m2) and anorexia nervosa.
Parental history of hip fracture.
Past history of fragility fracture (especially hip, wrist and spine fracture).
Corticosteroid therapy (current treatment at any dose orally for three months or more).
Cushing’s syndrome.
Alcohol intake of three or more units per day.
Smoking.
Falls and conditions increasing the risk of falls, such as:
Visual impairment.
Lack of neuromuscular co-ordination or strength.
Cognitive impairment.
Sedative medication and alcohol.

230
Q

what is a T score?

A

scoring system for osteoporosis that compares bone mineral density (BMD) of patient to the young adult mean.
osteoporosis then defined as anything below -2.5 SDs away from that mean.
osteopenia = between -1 and -2.5 (reduced density but not osteoporosis yet)

231
Q

what are DEXA scans and when should they be used in investigation of osteoporosis?

A

dual energy X ray absorpimetry - only use after assessing fracture risk with FRAX or Qfracture.
often wouldn’t bother if >75yo as likely will treat anyway, so doesn’t change the management much.

232
Q

in a patient taking moderate/high dose steroids, when should you add bone protection?

A
add it from the start if think they'll be on it for >3 months - don't wait till 3 months have passed!
use alendronate (bisphosphonate) - common side effect of GI upset, switch to risedronate
233
Q

what treatment options are there for osteoporosis?

A

advise adequate calcium/vit D intake - consider supplementation.
regular weight bearing exercise, stop smoking, reduce alcohol consumption.
bisphosphonates = alendronic acid/alendronate 70mg once weekly - take on empty stomach, 30 mins before any other food/meds, sitting upright for 30 mins after, drink loads of water. common GI upset - switch to risedronate if so.

other meds - strontium (not recommended any more)
raloxifene (works on oestrogen) - used if bisphosphonates CI’d
denosumab - monoclonal ab, used further down line of treatment

234
Q

what is osteoarthritis? how does it present?

A

‘wear and tear’ arthritis - now thought to be metabolically active.
usually localised to knee or hip or base of thumb initially - pain on movement, crepitus, worse at end of day, background pain at rest, gelling (stiffness after rest), joint instability

certain occupations, e.g. farming
237
Q

describe the initial management of osteoarthritis

A

reduce load on joint - physio, walking aids
exercise improves local muscle strength and reduces pain and disability
avoid pharmacological treatment where poss - local heat, TENS etc
then 1g paracetamol QDS first line ± topical NSAIDs (if knee or hand)
second line - codeine, NSAIDs (+ omeprazole), topical capsaicin

238
Q

describe further management of osteoarthritis (beyond lifestyle changes + drugs)

A

240
Q

what hand signs are seen in rheumatoid arthritis?

A

ulnar deviation of fingers
dorsal wrist subluxation
Boutonniere and swan-neck deformities of fingers
Z deformity of thumbs

241
Q

what investigations would you do for rheumatoid arthritis?

A
rheumatoid factor (positive in 70%)
anticyclic citrullinated peptide antibodies (ACPA/anti-CCP) - very specific for RA
inflammation means - raised platelets, ESR and CRP
XR - may be normal, show periarticular osteoporosis or soft tissue swelling - late on shows loss of joint space, erosions and joint destruction
242
Q

when should you refer a patient with suspected rheumatoid arthritis?

A

all patients with persistent synovitis should be reviewed.
refer urgently if:
- the small joints of the hands or feet are affected
- more than one joint is affected
- there has been a delay of 3 months or longer between onset of symptoms and seeking medical advice.

new NICE guidelines say they should be seen by rheumatology within 3 weeks

243
Q

what non-pharmacological management options are there for RA?

A

use the MDT!!
physio
OT
hand exercise programmes
podiatry
psychological therapies - consider IAPT referral, ensure regularly screening for depression
encourage mediterranean diet - but no link between any particular foods and RA generally
complementary therapy - welcome to try, but shouldn’t replace conventional treatments

244
Q

when should you consider referring a patient for surgical management of RA?

A

if any of the following do not respond to optimal non-surgical management:
persistent pain due to joint damage or other identifiable soft tissue cause
worsening joint function
progressive deformity
persistent localised synovitis.
ALSO -
if they have any of the following complications for a specialist surgical opinion before damage or deformity becomes irreversible:
imminent or actual tendon rupture
nerve compression (for example, carpal tunnel syndrome)
stress fracture.

245
Q

describe the initial drug management of RA

A

treat-to-target - patients should have regular disease monitoring/reviews e.g. monthly rheumatology appts until they’re in remission/meet disease control target (generally should be remission!)

first line - monotherapy with conventional DMARD - methotrexate, sulfasalazine, hydroxychloroquine - ideally start < 3 months after symptom onset.
titrate dose up to have effect - if that doesn’t work, try the above in combination (step-up strategy)

246
Q

describe the further drug management of RA (after conventional DMARDs have failed)

A

biologics - sarilumab, dalimumab, etanercept, infliximab, certolizumab pegol, golimumab, tocilizumab and abatacept - all used in combination with methotrexate

rituximab used if the above don’t work/are intolerated
tocilizumab also used later on in treatment steps.

247
Q

how should RA ‘flares’ be managed?

A

oral NSAIDs + PPI

short term course of steroids - oral, or intra-articular injections if disease quite localised

248
Q

list some extra-articular complications of RA

A

respiratory: pulmonary fibrosis, pleural effusion, pulmonary nodules, bronchiolitis obliterans, methotrexate pneumonitis, pleurisy

A

give oxygen
salbutamol nebs (or via spacer if no nebuliser available)
steroids - po pred or iv hydrocortisone

if no response - ADMIT
if any life-threatening signs/symps - ADMIT

252
Q

what is asthma? what are the 3 characteristic features?

A

paroxysmal, reversible airways obstruction
3 characteristic features:
- Airflow limitation— usually reversible spontaneously or with treatment
- Airway hyper-responsiveness to a wide range of stimuli
- Inflammation of the bronchi

253
Q

what clinical features increase likelihood that a patient has asthma?

A
> 1 of:
Wheeze
Breathlessness
Chest tightness
Cough
Particularly if:
Symptoms are worse - at night/ early morning, with exercise, allergen and/ or cold air exposure, after aspirin/ beta-blockers
PMH of atopy
FH asthma and/or atopy 
Widespread wheeze
Unexplained low FEV1 or PEFR
Unexplained eosinophilia
254
Q

what clinical features make it less likely that a patient has asthma?

A

Prominent dizziness, light-headedness, peripheral tingling
Chronic productive cough without wheeze/breathlessness
Normal examination of chest when symptomatic
Voice disturbance
Symptoms with colds only
Smoking history (> 20 pack y)
Cardiac disease
Normal PEFR/ spirometry when symptomatic

255
Q

what tests should be done to diagnose asthma?

A

spirometry preferred - FEV1/FVC ratio <70% = airway obstruction - but this can be normal if asymptomatic at the time of assessment!

peak flow diaries more useful in monitoring controlled asthma, but are sometimes used

fractional exhaled nitric oxide testing can be used if “intermediate” probability - more nitric oxide meant to indicate more inflammation in lungs

might use reversibility testing - if airflow obstruction at time, test FEV1 before and after give salbumatol inhaler. if no airflow obstruction, test before and after trial of treatment with beclometasone

256
Q

describe the step-wise management of asthma in adults

A

1) SABA - reliever inhaler, salbutamol (blue)
step up if using blue inhaler 3 times a week
2) add low dose ICS
3) add leukotriene receptor agonist, review in 4-8 weeks
4) add LABA, continue LTRA if helpful
5) SABA ± LTRA, plus switch ICS/LABA for a maintenance and reliever therapy (MART), that includes a low-dose ICS
5) increase ICS to moderate dose - either as MART, or switch to LABA + ICS maintenance with SABA reliever

6) SABA +/- LTRA + one of the following options:
- increase ICS to high-dose (only as part of a fixed-dose regime, not as a MART)
- a trial of an additional drug (for example, a long-acting muscarinic receptor antagonist or theophylline)
- seeking advice from a healthcare professional with expertise in asthma

257
Q

what is COPD? what causes it?

A

slowly progressive disorder characterized by airflow obstruction with little or no reversibility

SMOKING
Genetic— bronchial hyperresponsiveness; alpha1-antitrypsin deficiency
Race— Chinese and Afro-Caribbeans have reduced susceptibility
Diet— poor diet and low birthweight

258
Q

what features of a history would make you consider COPD?

A

Consider in any patient > 35y with a risk factor for COPD (generally smoking) and ≥ 1 of:
SOBOE - use an objective measure, e.g. MRC dyspnoea scale to grade breathlessness
Chronic cough
Wheeze
Regular sputum production
Frequent winter ‘bronchitis’

259
Q

list some possible signs of COPD

A
might be none! or any of:
Hyperinflated chest ± poor chest expansion on inspiration
↓ cricosternal distance
Hyperresonant chest with ↓ cardiac dullness on percussion
Wheeze or quiet breath sounds
Paradoxical movement of lower ribs
Use of accessory muscles
Tachypnoea
Pursing of lips on expiration (purse lip breathing)
Peripheral oedema
Cyanosis
↑ JVP
Cachexia
260
Q

what results on spirometry indicate airflow obstruction?

A

FEV1/FVC <70%, FEV1 <80% (some places say 70%) predicted

261
Q

what investigations should be ordered if a patient presents with symptoms that sound like COPD?

A

spirometry
CXR to exclude other pathologies
FBC
calculate BMI

if early onset/family linked - consider testing for alpha1 antitrypsin deficiency

262
Q

what does NICE recommend regarding management of stable COPD?

A

general - smoking cessation, pneumococcal vaccine, annual flu jab
SABA or SAMA (ipatropium) is first line - if remain symptomatic then treat according to FEV1
FEV1 > 50% predicted - add LABA (salmeterol) or LAMA (tiotropium)

next:
if on LABA, switch to LABA + ICS combi
if on LAMA, keep that and add LABA + ICS combi

then maybe try theophylline
mucolytics can be ‘considered’

263
Q

how does an acute exacerbation of COPD present?

A

One or more of:

↑ dyspnoea— marked dyspnoea, tachypnoea (> 25 breaths/min), use of accessory muscles at rest and purse lip breathing are signs of severe exacerbation
↓ exercise tolerance— marked ↓ in activities of daily living is a sign of severe exacerbation
↑ fatigue
↑ fluid retention— new-onset oedema is a sign of severe exacerbation
↑ wheeze
Chest tightness
↑ cough
↑ sputum purulence
↑ sputum volume
Upper airways symptoms, e.g. colds, sore throats
New-onset cyanosis— severe exacerbation
Acute confusion— severe exacerbation

264
Q

what causes acute exacerbations of COPD?

A

infections or pollutants

organisms:
Haemophilus influenzae (most common cause)
Streptococcus pneumoniae
Moraxella catarrhalis

265
Q

what does NICE say about managing acute exacerbations of COPD?

A

increase frequency of bronchodilator use and consider giving via a nebuliser

give prednisolone 30 mg daily for 7-14 days (useful qu if assessing severity of COPD - how many times were you on steroids last winter?)

it is common practice for all patients with an exacerbation of COPD to receive antibiotics. NICE only recommend giving oral antibiotics ‘if sputum is purulent or there are clinical signs of pneumonia’

if giving abx - Use broad-spectrum antibiotic, e.g. clarithromycin 500mg bd or doxycycline 100mg od/ bd

266
Q

when should a COPD patient be put on LTOT?

A

Assess patients for suitability if any of the following:

very severe airflow obstruction (FEV1 < 30% predicted). Assessment should be ‘considered’ for patients with severe airflow obstruction (FEV1 30-49% predicted)
cyanosis
polycythaemia
peripheral oedema
raised jugular venous pressure
oxygen saturations less than or equal to 92% on room air

Assessment is done by measuring ABGs on 2 occasions at least 3 weeks apart in patients with stable COPD on optimal management.

Offer LTOT to patients with a pO2 of < 7.3 kPa or to those with a pO2 of 7.3 - 8 kPa and one of the following:
secondary polycythaemia
nocturnal hypoxaemia
peripheral oedema
pulmonary hypertension

LTOT involves 15h a day of supplementary O2 via oxygen concentrator.

267
Q

Drugs (NSAIDs, TCAs, SSRIs, iron supplements, anticholinergics, nitrates, alendronic acid)
Surgery for achalasia
268
Q

what causes GORD?

A

retrograde flow of gastric contents through incompetent gastro-oesophageal junction - gives heart burn type symptoms.
conditions causing GORD:
Oesophagitis (defined by mucosal breaks) ± oesophageal ulcer
Benign oesophageal stricture
Intestinal metaplasia: Barrett’s oesophagus
Oesophageal haemorrhage
Anaemia

269
Q

how does GORD present?

A

Heartburn: most common symptom. Burning retrosternal or epigastric pain which worsens on bending, stooping or lying, and with hot drinks. Relieved by antacids.

Other symptoms:
Waterbrash— mouth fills with saliva
Reflux of acid into the mouth (bad/funny taste) - especially on lying flat
Nausea and vomiting
Nocturnal cough/ wheeze due to aspiration of refluxed stomach contents

270
Q

when would you consider ordering an endoscopy for a patient with likely GORD?

A
symptoms for >4 weeks
persistent vomiting
GI bleeding/iron-deficient anaemia
palpable mass
age >55
dysphagia
symptoms despite treatment
weight loss
271
Q

what types of investigations might be ordered for a GORD patient?

A

endoscopy
barium swallow - identifies hiatus hernia
oesophageal pH monitoring / manometry - useful if endoscopy normal

272
Q

outline management options for GORD

A

lifestyle - raise bed head, weight loss, smoking cessation, avoid spicy food/alcohol/citrus/hot drinks/choc, small regular meals
drugs - antacids or alginates, PPI if oesophagitis or unresponsive to initial treatment.
surgery - aims to increase resting LOS pressure, consider in severe GORD - Nissen fundoplication

273
Q

what kind of inhalers are seretide/symbicort? side effects?

A

compound inhalers - contain ICS and LABA
Seretide = fluticasone and salmeterol
Symbicort = budesonide and formoterol

SEs - ICS’s cause oral thrush (rinse mouth out), hoarse voice.
LABAs can cause tremor, tachycardia, arrhythmias, muscle cramps.

advise patient - must use every morning to work, might take a few days to feel benefit. rinse mouth and gargle immediately after - prevents oral thrush/hoarse voice.

274
Q

what are alginates? what are they used for? side effects to warn patient?

A

used in GORD/dyspepsia - act to increase viscosity of stomach contents, reducing reflux of stomach acid into oesophagus - forms floating ‘raft’ on top of acid as well.
usually used with antacids as Gaviscon/Peptac.
antacids work by buffering stomach acids.

SEs - rare, but diarrhoea or contraception. can reduce absorption of other drugs.

275
Q

what are bisphosphonates? how do they work? important SEs?

A

e.g. alendronate
used first line for pts at risk of osteoporotic fragility fractures
they reduce bone turnover, by inhibiting action of osteoclasts (cells responsible for bone resorption)
patients take it once a week, before any food/drink, with lots of water, sitting upright for 30 mins after.

SEs - oesophagitis, hypophosphataemia. avoid in severe kidney failure, CI if hypocalcaemia or upper GI disorders.

276
Q

how do beta2-agonists work? how are they classified? important SEs?

A

SABA (salbutamol, terbutaline) or LABA (salmeterol, formoterol)
beta2 receptors are found in smooth muscle of bronchi, GI tract, uterus and blood vessels - stimulation by SABA/LABA causes smooth muscle relaxation, improving airflow, reducing breathlessness.

SEs - tachycardia, palpitations, anxiety, tremor. LABAs can cause muscle cramps.

277
Q

how do antimuscarinic bronchodilators work? how are they classified? important SEs?

A

SAMA (ipratropium) vs LAMA (tiotropium)
bind to muscarinic receptor, competitively inhibiting acetylcholine - reduce smooth muscle tone and secretions by blocking action of muscarinic receptor.

SEs - none really, might get a dry mouth.

278
Q

how do inhaled corticosteroids work? SEs?

A

e.g. beclometasone, budesonide, fluticasone
used in asthma and COPD
‘dampen down’ inflammation in lung - hardly any absorbed into the body.
basically pass into cytoplasma, activate receptors then modify transcription of loads of genes - results in downregulation of pro-inflammatory interleukins, cytokines etc, and upregulation of anti-inflammatory ones - reduces mucosal inflammation, widens airways, reduces mucus secretion.
both improves symptoms and reduces exacerbations.

SEs - very local - oral thrush and hoarse voice.

279
Q

what are proton pump inhibitors? important SEs?

A

e.g. omeprazole, lansoprazole

reduce gastric acid secretion - irreversibly inhibit H+/K+-ATPase in gastric parietal cells (proton pump) which normally secretes H+ - can suppress gastric acid production almost completely cos they act on this last step.

SEs - GI disturbance, headache

280
Q

what are H2-receptor antagonists? important side effects?

A

e.g. ranitidine
used in GORD/peptic ulcer disease
reduce gastric acid secretion - not completely though, so PPIs better really - ranitidine only blocks one pathway from stimulating proton pump

SEs - usually well tolerated, might get diarrhoea, headache, dizziness

281
Q

what would histology of a biopsy taken at endoscopy from someone with coeliac disease show?

A

villous atrophy, raised intra-epithelial lymphocytes, and crypt hyperplasia

282
Q

what is coeliac disease? how does it present?

A

gluten sensitivity resulting in inflammation of bowel and malabsorption - T cell mediated autoimmune disease of small bowel.

associated with HLA-DQ2 and HLA-DQ8, and other autoimmune diseases
usually presents with kinda vague history of diarrhoea and weight loss/anaemia. also steattorrhoea, abdo pain, bloating, N&V, aphthous ulcers, angular stomatitis, fatigue, weight loss, osteomalacia

283
Q

how is coeliac disease investigated?

A

tissue transglutaminase
anti-endomyseal antibodies

also do - FBC, ESR/ CRP, B12, folate, ferritin, LFTs, Ca2 +, TFTs, and stool sample for M, C& S (if diarrhoea)

284
Q

how is coeliac disease managed?

A

gluten free diet - can prescribe gluten free breads, biscuits etc. refer to dietician.
give pneumococcal vaccine - at risk due to secondary hyposplenism

285
Q

what are some complications of coeliac disease?

A

anaemia, secondary lactose-intolerance, GI T cell lymphoma (rare), general raised risk of malignancy (gastric, oesophageal, bladder, breast, brain), myopathies, hyposplenism, osteoporosis

286
Q

what is IBD?

A

ulcerative colitis and crohns:
chronic, relapsing-remitting diseases characterized by acute, non-infectious inflammation of the gut.
UC - inflammation limited to mucosa. varies from disease limited to the rectum (proctitis) to affecting the whole colon (pancolitis).
Crohn’s, any part of the gut from mouth to anus can be affected with normal bowel between affected areas (skip lesions).

287
Q

what is the impact of smoking on UC?

A

protective factor!

288
Q

briefly describe the pathology of UC

A

relapsing and remitting inflammatory disorder - hyperaemic/haemmorrhagic granular colonic mucosa ± pseudopolyps formed by inflammation - might see punctate ulcers extedning into lamina propria, but inflammation not normally transmural

289
Q

symptoms/signs of UC

A

symps - episodic or chronic diarrhoea (± blood/mucus), crampy abdo discomfort, urgency/tenesmus (rectal UC) - frequency of bowel movements relates to severity.

signs - might be none, or clubbing, aphthous oral ulcers, erythema nodosum, pyoderma grangrenosum, conjunctivity, episcleritis, iritis, sacroiliitis etc etc

290
Q

what investigations would you do for a patient with suspected UC?

A

bloods - FBC, ESR, CRP, U&E, blood culture
stool MC&S to exclude infection
colonoscopy - shows disease extent, allows biopsy

291
Q

give some complications of UC

A

perforation
bleeding
toxic megacolon
venous thrombosis - higher risk

292
Q

how do you manage UC?

A

induce remission with a 5-aminosalicylic acid (sulfasalazine or mesalazine), steroids (prednisolone) can also help.
maintenance - often stay on 5-ASA
also - suppositories (e.g of pred or mesalazine) helpful in proctitis, foams PR can help procto-sigmoiditis.

immunomodulation (e.g. azathioprine, methotrexate, infliximab) used if steroids not inducing remission
surgery - eventually - resulting in stoma usually.

293
Q

what is Crohn’s disease/describe pathology

stool - MC&S to exclude infection
colonoscopy and rectal biopsy

297
Q

management of Crohn’s

A

mild attack - mesalazine or prednisolone
severe - admit, IV hydrocortisone, consider surgery
there’s loads of weird and wonderful drugs can try in specialist care e.g. azathioprine, methotrexate, TNF alpha inhibitors etc
surgery usually last resort if other management failed - never curative

298
Q

what is IBS?

A

chronic (> 6mo) relapsing and remitting condition of unknown cause, with symptoms including ABCs: Abdominal pain or discomfort; Bloating; and Change in bowel habit.

299

Signs - pallor, ‘lemon tinge’ to skin, pulmonary/ peripheral oedema, pericarditis, pleural effusions, metabolic flap, ↑ BP, retinopathy

303
Q

define CKD

A

impaired renal function for >3 months with abnormal structure/function - OR - GFR <60 for >3 months ± evidence of kidney damage

304
Q

explain the classification system for CKD

A

normally no symptoms till stage 4+:
stage / GFR / notes
stage 1 = >90 = normal or high GFR with evidence of renal damage
stage 2 = 60-89 = slightly low GFR with evidence of renal damage
stage 3A/B = 45-59 / 30-44 = moderately low GFR with or without evidence of renal damage
stage 4 = 15-29 = severely low GFR, ± evidence of renal damage
stage 5 = <15 = established renal failure

evidence of renal damage = proteinuria, haematuria, evidence of abnormal anatomy/systemic disease

305
Q

who should be screened for CKD?

A

patients with:
diabetes
hypertension
cardiovascular/cerebrovascular disease
structural renal disease, known stones or BPH
recurrent UTIs or childhood hx of vesicoureteric reflux
multisystem disorders which could involve the kidney eg. SLE
FHx of end-stage renal failure or known hereditary disease e.g polycystic kidneys

306
Q

what investigations might you order for a patient with newly diagnosed CKD?

A

Urine - MC& S, microalbuminuria, albumin:creatinine ratio protein:creatinine ratio, RBCs, glucose
Bloods - U& E, creatinine, eGFR, glucose, Ca2 +, PO4 – urate, protein, FBC, ESR, serum electrophoresis

Renal tract USS If progressive or advanced (stage 4/ 5) disease, refractory ↑ BP, haematuria, or palpable bladder/ lower urinary tract signs
consider renal biopsy if rapidly progressive/unclear cause and normal size kidneys

307
Q

when should you refer a patient with CKD?

A
  • stage 4 or 5
  • moderate proteinuria unless due to DM and already appropriately treated
  • proteinuria with haematuria
  • rapidly falling eGFR
  • poorly controlled hypertesion despite 4+ antihypertensives
  • known/suspected rare/genetic cause
  • suspected renal artery stenosis
308
Q

how do you manage CKD?

A
  • find and treat reversible causes
  • limit progression/complications - tight BP control, treat raised PTH to prevent renal bone disease, reduce CVD risk factors, dietician advice
  • symptom control - monitor for anaemia, acidosis, oedema, restless legs
  • prepare for renal replacement therapy
309
Q

give some basic info on renal replacement therapy options

A

dialysis normally started at GFR of about 8-10
haemodialysis - need AV fistula normally to get good enough access, blood passed over membrane and waste removed, can do ultrafiltration to remove excess fluid as well
haemofiltration - used in critically ill but inappropriate for long term as takes too long
peritoneal dialysis - uses the peritoneum as membrane - catheter inserted into cavity, infusion of fluid, then solutes can move across - can be done at home, quite simple.

dialysis has a massive impact on QoL!!

the ultimate in renal replacement therapy is renal transplant - but major surgery, long term immunosuppression, risk of complications etc

Q

what causes type 1 diabetes?

A

insulin deficiency due to autoimmune destruction of insulin-secreting pancreatic beta cells.
associated with HLA DR3 ± DR4 - and other autoimmune diseases.
they will be insulin dependent, can present in DKA

311
Q

what causes type 2 diabetes?

A

reduced insulin secretion and raised insulin resistance - associated with obesity, sedentary lifestyle, calorie and alcohol excess.
progresses from preliminary phase of impaired glucose tolerance or impaired fasting glucose.

312
Q

what are the WHO cut offs for diabetes?

A

symptoms of hyperglycaemia (e.g. polyuria, polydipsia, weight loss, vision blurring, genital thrush, lethargy) AND raised blood glucose once - fasting = 7+, random = 11.1+ mmol/L
OR
2 separate occasions of raised blood glucose using above cut offs OR oral glucose tolerance test 2h value 11.1+ mmol/L

HbA1c noraml at 48+ mmol/L (or 6.5%) - doesn’t exclude DM, don’t bother using in kids, pregnancy or T1DM

313
Q

describe the non-drug management options for T2DM

A

LIFESTYLE - education programme, smoking cessation, weight loss, good nutrition
start statin, control BP, foot care
inform DVLA - don’t drive if hypo spells - loss of hypo awareness = loss of license (permanent if HGV driver)
influenza and pneumococcal jabs

314
Q

what are the drug management options for T2DM?

A

1) metformin (biguanide) - only effective if some insulin production still, no hypo risk, can aid weight loss
second-line / if metformin CI’ed - DPP4 inhibitors, pioglitazones or sulfonyureas

sulfonyurea - e.g. glicazide - increase insulin secretion, can cause hypos and weight gain
pioglitazone - increases insulin sensitivity, can cause hypos, fractures, fluid retention
DPP4 inhibitors - aka gliptins e.g. sitagliptin

3rd line is basically combinations of the above
then you go to insulin

315
Q

contra-indications for pioglitazone

A
heart failure or history of heart failure
hepatic impairment
diabetic ketoacidosis
current, or a history of, bladder cancer
uninvestigated macroscopic haematuria.
316
Q

when would you avoid using metforming for T2DM?

A
reduce eGFR (<36) 
also if very elderly, severe heart disease, liver disease, alcohol problems
317
Q

what different types of insulin therapy are available?

A

Rapid-acting analogues (e.g. insulin lispro— fastest acting; peak 0– 3h after injection; last 2– 5h; give just prior to meals)

Soluble (clear) human, porcine, or bovine (e.g. Actrapid — short-acting; peak 2– 6h after injection; last 8h; give 15– 30min before meals)

Intermediate- or longer-acting (cloudy) human, porcine, or bovine (e.g. Humulin I)— peak 4– 12h after injection; last up to 30h. Taken alone, od/ bd to provide background insulin, or with short/ rapid-acting insulin

Long-acting insulin analogues (e.g. insulin glargine)— last 24h; provide background insulin; as no peak, associated with ↓ risk of hypoglycaemia

Pre-mixed— combination of short- + long-acting insulin, e.g. 30%: 70%

318
Q

list some complications of diabetes

A
  • infection/lipohypertrophy and injection sites (advise rotation)
  • vascular disease - CVD, stroke - MASSIVE issue
  • nephropathy
  • diabetic retinopathy
  • cataracts
  • peripheral neuropathy / foot ulcers
319
Q

how does diabetes mellitus present?

A

Acute - ketoacidosis or hyperosmolar non-ketotic coma Subacute - weight ↓, polydipsia, polyuria, lethargy, irritability, infections (candidiasis, skin infection, recurrent infections slow to clear), genital itching, blurred vision, tingling in hands/ feet
With complications - skin changes, neuropathy, nephropathy, arterial or eye disease
Asymptomatic - incidental finding or through risk stratification

320
Q

list some causes of hyperthyroidism

A

Graves’ disease
Toxic nodular goitre— older women with past history of goitre
Thyroiditis - inflammation of thyroid - e.g. postpartum
Amiodarone
Exogenous e.g. thyroid replacement post hypothyroidism
Kelp ingestion

321
Q

how might hyperthyroidism present?

A
Weight loss
Tremor
Palpitations
Hyperactivity
AF
Hyperhidrosis
Eye changes
Infertility
Alopecia
322
Q

what are the management options for hyperthyroidism?

A

beta blockers - rapid symptom control
carbimazole - anti-thyroid meds - often given as ‘block-replace’ in combo with thyroxine
radioiodine - absorbed into thyroid then destroys it - usually become hypothyroid after so then need replacement
thyroidectomy - risk of damage to recurrent laryngeal nerve (hoarse voice) and hypoparathyroidism, might need thyroxine

323
Q

symptoms/signs of hypothyroidism

A
symps - tired, lethargic, low mood, cold disliking, weight gain, constipation, menorrhagia, myalgia, cramps, weakness
signs - BRADYCARDIC
Bradycardic
Reflexes relax slowly

Immobile ± ileus
CCF
324
Q

what TFT results would you expect in hyper vs hypo thyroidism?

A
hyper = TSH low (suppressed), T4 and T3 high
hypo = TSH high, T3/T4 low
325
Q

give some causes of hypothyroidism

A

primary atrophic hypothyroidism
Hashimoto’s thyroiditis
