asthma guidelines children 5-12 yrs

A

Step 1 - Inhaled short acting b2 agonist as required.

If benefit from LABA but control still inadequate, continue LABA and increase steroid up to 400 mcg/day, if not already on this dose. If no response to LABA, stop and try other therapies, for example, leukotriene receptor antagonist or SR theophylline.

Q

horners

A

damage to sympathetic pathway
miosis (constricted pupil)
anhidrosis
ptosis

137
Q

acute glaucoma triggers

A

pupil dilated
hypermetropia ( long sightedness) / short
meds which dilate pupil

138
Q

DM2 aims of treatment

A

antihypertensives for macro and microvascular complications
lower hba1c for microvascular comps
lipid lowering for macrovascular comps as main population

139
Q

heart failure diagnosis

A

previous MI: echo
no MI :serum BNP, if raised then echo
echo normal, consider other cause for raised BNP, then treat

140
Q

heart failure treatment ( all types)

A

diuretics,
calcium channel blockers amlodipine( not verapamil / diltiazem) for comorbid HTN / angina
anticoags, for sinus rhythm and hx of VTE, intracardiac thrombus, left ventricular aneurysm
aspirin 75-150mg with atherosclerotic arterial disease
amiodarone ? on specialist advice. needs 6 monthly clinical review for thyroid and LFT

141
Q

left ventricular heart failure

A

one drug at a time
ACE eg if diabetic / fluid overload
BB eg if angina / HTN (bisoprolol, carvedilol nebivolol)
then specialist advice for hydralazine, nitrate, ARB, dig, ivrabradine

142
Q

ARB

A

eg candesartan, losartan, valsartan

143
Q

aldosterone antagonists

A

spironolactone, epleronone

144
Q

stable angina

A

give b-blocker or calcium channel blocker.
if intolerant / not working consider long acting nitrate (ivrabradine, nicorandil, ranolazine)
assess every 2-4 weeks.
antiplatelet therapy: 75mg aspirin or if stroke / PVD clopidogrel
ACEi if stable angina and HTN, DM, heart failure,

145
Q

anitplatelets for secondary prevention of CVD

A
in pts with 
angina
MI
stroke / TIA
peripheral arterial disease
AF ( usually anticoagulants)
146
Q

MI

A

aspirin long term
non ST elevation: add clopidogrel for 12 months
ST elevation: clopidogrel for a month

147
Q

intention to treat analysis

A

analyses all patients randomised to study eg patient fall out may bias things

148
Q

Relative Risk Reduction

efficacy

A

effect in ideal / lab conditions

150
Q

effectivenes

A

effect in real world

151
Q

incidence

A

new cases over fixed time

Q

prevelence

A

rate of a disorder in fixed population at a specific time

153
