stroke
44
examination of person vertigo
ear examination
neuro exam
cv exam- arrythmia, heart valve
danish - cerebellum examn
rombergs test
dix hallpike manouvere- dx BPPV

trauma
nose picking
blowing nose vigourosuly
colds
sinusitits
coagulation disorders- thromocytopenia, von willebrands disease
anti coag meds
snorting coacain
tumours
can swallow blood- look likevomit blood if vomit
53
nose bleed bilateral
more likely from posterio and increase risk aspirate
54
mnangment nose bleeds
normally resov
lean head forward and sit up
oinch soft nose 10-15 mins
not resovled after this time, sevre, haemodynamically unstable, both nostril:
hosp
nasalpacking with nasal tampons/ inflatable packs
nasal cautery with silver nitrate sticks
after rx consider prescribing naseptin nasal cream- chlorhexadine and neomycin- 4 a day for 10 days- reduces crusting, inflam and infection
ci= peanut or soya allergy
55
ci fro naseptin nasal cream
peanut soya allergy
56
sinusitits
inflammation of paranasal sonuses
usally accompanied by inflamation of nasal cavity=> rhinosinusitits
57
acute sinusisits and chronic duration
acute- less 12 weeks
chronic - more 12 weeks
58
sinsues function
produce mucous and drain into nasal cavities via holes- ostia
blockage of these holes prevents drainage and so get sinusiits
59
casues of sinusitis
infection- esp get after a VIRAL upper resp tract infection
allergies with alergic rhinitits (hayfever)
obstrucition of drainage- foregin body, trauma, nasal polyp
smoking
60

61
presentation sinusitis
often after viral upper resp tract infection
facial swelling over affected area
facial pressure
facial pain / headache
nasal congestion
nasal discharge
loss of smell
tenderness on palpation of affected area
inflam and oedema of nasal mucosa
dishcarge
fever
sighns of systemic illness- tachycardia
chronic similar
62
chronic sinutisist associated with what
nasal polyps
63
investigfations sinusitis
nthing
if persitant despite rx:
nasal endoscopy
ct scan
64
management of acute sinusits
nothigng - usally resocles 2-3 weeks and due to viral so not keen for abx
if not improved after 10 days of symtoms then:
high dose nasal steroid spray for 14 days = mometasone 200mcg BD
or
delayed abx prescition- if worsening or not improving whtin 7 days abx= phenoxymethylpenicillin
65
managemnt chronic sinusitis
steroid nasal spray/ drops= mometasone/ fluticasone
saline nasal irrigation
functional endocopic sinus surgfery
66
technique of nasal spray
tilt head foreward slighlty
left hand for r nostril - not directly to septum
not sniff during spray
inhale gently through nose after spray
ask do you taste it in back of mouth after it - shouldnt as means not in nose
67
tonsilits- which tonstils
inflammation of tonsils
palatine tonsils in waldeyers ring
68
cause of tonstitlits
most common cause is viral!
bacterial- most common is streptococcus pyogenes
second most common is streptococcus pneumoniae
other bacterial:
moraxella catarrhalis
haemophilus influenzae
staphylcoccus aureus
69
presentationtonsitltis
fever- over 38
sore throat
pain on swallowing
inflammed, red, enlarged tonsils
can have exudate
may have anterior cervical lymphadenopathy
70
how to know if bacterail tonsitlits
feverPAIN score- 4 or more likely bacteria
Centor criteria - 3 or more liekly bacterial
71
feverPAIN score criteria
fever- during previous 24hrs
purulence- pus
attended within 3 days of onset
inflammed
no cough.coryza
if 4 or more then tonsiltits bacterial likely = abx
72
centor score
fever
tonsilar exudates
no cough
lymphadenopathy - tender anterior cervical lymph nodes
3 or more ikly bacterial tonsiltis
73
managemnt of tonisittlis- viral and bacterial and what abx givr
consider admit if:
immunocompromised
dehydrated
strifor
resp disease
cellulitis
peritonsilar abscess
systemically unwell
viral:
resolve by self- use soimple analgesia for pain and fever - paracetamol and nsaids
if not settled with 3 days/ fever over 38.3 then return and consider abx
score centor 3 or more, painFEVER 4 or more consider abx or if at risk of severe infection - young infant, sign co morbities, hx of rheumatic fever, immunocompromised
consider delayed prescirbtio if not imrpvoe / worse 2-3 days
abx= penicillin v (phenoxymethylpenicillin)- narrow good agasint streptococcus pyogenes
if pen allergy- clarightromycin
74

80
presentation quinsy/peritonsillar abscess
like tonsilits
fever
pain swallowing
sore throat
pain radiate to ear
tender cervical anterior lymoh nodes
neck pain
indicate abscess and not tonsiltis:
change in voice- pharangeal swelling

erythma and swelling beside the tonsils too
81
mangment peritonisllar abscess/ quinsy
hos- incision and drainage under GA
abx before and after surgey as usually bacterial casue
co - amoxiclav- want broad specturm
some surgeons give steorids- dexamethoason- to reduce inflam and help recovery
82

damage to teeth
85
treatment for post tonsillectomy bleeding
severe- can be lifethreatenigng esp if aspiration of blood
5% occur
can occur up to 2 weeks afger op
ent reg
iv acess- bloods= fbc, clotting screen, group and save and crossmatch
keep pt calm and appropriate analgesia
sit pt up and encouage spit out blood and not swallow it
nbm
iv fluids - maintence and resus if needed
if severe bleedig or airway compromised may need anaethesitits for intubatio n
stop the bleeding:

no skin changes
can leaveor can remove
100
branchial cyst
s and s
congenital
normally second branchial cleft
anteior to sternocleidomastoid muscle and under jaw angle
round soft
transillumiate
treat- conservative or can remove if recurrent infection
101
lump on midline that moves when stick tongue out/ swallow
thyroglossal cysts
102
thyroglossal cyst
and s and s
embryo thryoid gland moves down from base of tongue and leaves a thryoglossal duct which then closes
sometimes this persitis and fluid cyst can occur
midline in neck
mobile
soft
non tender
fluctuant
move with tongue up and down wehn stick tongue out and move when swallow- upawards
103
investigations and treamnt and compliation thryoglossal cyst
us/ct
remove
infection complication
104
differential for midline lump on neck
thryoglossal cysts
ectopic thyroid tissue
105
drugs can casue goitre
lithium
amiodarone
106
goitre will they move on tongue protrustion?
swallowing?
no
thryoglossal cysts will move on tongue protursion as connected to base of tongue
Thyroid gland masses (e.g. a goitre) and thyroglossal cysts typically move upwards with swallowing.
Lymph nodes will typically move very little with swallowing.
An invasive thyroid malignancy may not move with swallowing if tethered to surrounding tissue
107
nasal polyps
growths of nasal mucosa that can occur in nasal cavity/ sinuses
108
important thing to remebr about nasal polyps
unilateral consider malignancy and refer to specilaist
109
assocaitions with nasal polyps
inflammation- chronic sunisitits/rhinitits (something there grwoing and obstructing so going to get inflammation which can then cause sinusuits/rhinitis depndisng locations)
asthma
samters triad- asthma, nasal polyps, aspiring intolerenace/allergy
cystic fibrosis
eosinophilic granulomatosis with polyangitits= chrug strauss syndrome
110
what presentations may you see nasal polyps
may be found in patients presenting with:
chronic rhinosinusitis
diff breathing through nose
snoring
nasal discharge
loss of sense of smell
111
how to view nasal polyps and what look like
nasal speculum/otoscope with large speculum
nasal endocsopy
round pale yellow/grey growths on the mucosal wall
112
managment nasal polyps
unilateral - refer to specialst to exclude malignancy
intranasal topical steroid spray/drops
if doenst work:
surgical removal:
intranasal polypectomy- if close to nostrils and visisble
endoscopic nasal polypectomy- polyps further insdie the nose/sinuses

episodes of apnoea at noght- wkaing at night - usually reported by partner
daytime sleepiness- ask re job may need amened duties
waking feeling unrefreshed
morning headache
snoring
reduced o2 sats at night
concentration problems
117
important questions to ask in pt with obstrucitve sleep apnoea
whats their occupation and if they have day time sleepiness - if so may need amend work dutites
118
severe obstructive sleep apnoea can cause
hypertension
heart failure
increase risk for stroke and mi
119
management obstrucitve sleep apnoea
refer to ent specialst/ specialsit sleep clinic-> sleep studies
1-correct revrisble risk factors- loose weight, stop drinking, stop smoking
