Which tonsils are commonly inflamed with tonsilitis
Palatine tonsils
Presentation of acute tonsillitis
- Sore throat
- Fever (above 38°C)
- Pain on swallowing
Examination of acute tonsillitis
Red, inflamed and enlarged tonsils, with/without exudates.
May be anterior cervical lymphadenopathy
Centor Criteria purpose
Used to estimate the probability that tonsillitis is due to a bacterial infection
Centor Criteria
Score of 3 + - high probability of bacterial tonsillitis
1 - Fever over 38ºC
1 - Tonsillar exudates
1- Absence of cough
1- Tender anterior cervical lymph nodes (lymphadenopathy)
FeverPAIN score purpose
Used to estimate the probability that tonsillitis is due to a bacterial infection
FeverPAIN score
A score of 2 – 3 gives a 34 – 40% probability, and 4 – 5 gives a 62 – 65% probability of bacterial tonsillitis:
- 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
Management of tonsillitis
Safety net - return if the pain has not settled after 3 days or the fever rises above 38.3ºC
Simple analgesia
Conside abx if Centor score >3 or FeverPain > 4
Delayed prescriptions
When to admit for tonsillitis
Consider admission if the patient is:
- immunocompromised
- systemically unwell
- dehydrated
- stridor
- respiratory distress
- evidence of a peritonsillar abscess or cellulitis
Penicillin allergy
Clarithromycin
