paeds ENT and opthalmology Flashcards
Fever pain score
Fever during previous 24 hours
P – Purulence (pus on tonsils)
A – Attended within 3 days of the onset of symptoms
I – Inflamed tonsils (severely inflamed)
N – No cough or coryza
A score of 2 – 3 gives a 34 – 40% probability (consider abx) and 4 – 5 gives a 62 – 65% probability of bacterial tonsillitis (give abx)
Management tonsilitis
- Oral phenoxymethylpenicillin (penicillin V?) for 5 or 10 days
- Clarithomycin or erythromycin(if penicillin allergic)5 days
Chronic tonsilitis referral criteria
> 3 episodes per year for 3 years
5 episodes per year for two years
7 episodes in a single year
Refer to ENT for tonsillectomy
Pathogen bacterial tonsilitis
GABS Group A Beta-haemolytic streptococcus
Two most common bacterial causes of otitis externa?
- pseudomonas aerginosa
- staphlococcus aureus
management of otitis externa
mild
1. acetic acid drops 2%
moderate:
1. Topical abtibiotic and steroid eg:
Otomize spray (Neomycin, dexamethasone and acetic acid)
Fungal:
1. Clotrimazole ear drops
Most common pathogen and others : otitis media
Streptococcus pneumoniae
Other common causes include:
Haemophilus influenzae
Moraxella catarrhalis
Staphylococcus aureus
If giving abx for otitis media, what is first line? what are alterantives?
- amoxicillin for 5 days
alternatives: erythromycin or clarythromycin
Management fungal otitis externa
clotrimazole ear drops
What should be avoided if perforated ear drum
Aminoglycosides (e.g., gentamicin and neomycin) are potentially ototoxic, rarely causing hearing loss if they get past the tympanic membrane.
Complication of otitis externa?
malignant otitis externa
Admission to hospital under the ENT team
IV antibiotics
Imaging (e.g., CT or MRI head) to assess the extent of the infection
pathophysiology otitis media
whilst viral upper respiratory tract infections (URTIs) typically precede otitis media, most infections are secondary to bacteria, particularly Streptococcus pneumonaie, Haemophilus influenzae and Moraxella catarrhalis
viral URTIs are thought to disturb the normal nasopharyngeal microbiome, allowing bacteria to infect the middle ear via the Eustachian tube
Presentation otitis media
otalgia
+ some children may tug or rub their ear
fever occurs in around 50% of cases
hearing loss
recent viral URTI symptoms are common (e.g. coryza)
ear discharge may occur if the tympanic membrane perforates
Examination otitis media
bulging tympanic membrane → loss of light reflex
opacification or erythema of the tympanic membrane
perforation with purulent otorrhoea
decreased mobility if using a pneumatic otoscope
Who should get antibiotics for otitis media
Symptoms lasting more than 4 days or not improving
Systemically unwell but not requiring admission
Immunocompromised or high risk of complications secondary to significant heart, lung, kidney, liver, or neuromuscular disease
Younger than 2 years with bilateral otitis media
Otitis media with perforation and/or discharge in the canal
