Q

What is the Centor Criteria?

A

Used to estimate the probability that tonsillitis is due to bacterial infection and will benefit from antibiotics

17
Q

Explain the Centor criteria

A

≥ 3 means 40-60 % probability of bacterial tonsillitis → offer antibiotics. Following is worth 1 pt each

  • Fever > 38ºC
  • Tonsillar exudates
  • Absence of cough
  • Tender anterior cervical lymphadenopathy
18
Q

What can be used as an alternative to the Centor critera?

A

FeverPAIN score

  • Fever during previous 24 hours
  • Purulence
  • Attended within 3 days of the onset of symptoms
  • Inflamed tonsils
  • No cough or coryza
19
Q

What values of the FeverPAIN score indicate likelihood of bacterial tonsillitis

A
  • 2-3 = 34 – 40% probability
  • 4-5 = 62 – 65% probability
20
Q

Management of tonsillitis that is likely viral?

A

Educate patients and give safety net advice

Advise simple analgesia with paracetamol and ibuprofen to control pain and fever

21
Q

What specific safety net advise would you give for tonsillitis?

A
  1. Return if the pain has not settled after 3 days OR
  2. If fever rises > 38.3ºC
22
Q

List 4 instances where we may consider prescribing antibiotics in tonsilitis?

A
  1. Centor score is ≥ 3,
  2. FeverPAIN score is ≥ 4
  3. Young infants
  4. Immunocompromised
  5. Significant co-morbidities
  6. History of rheumatic fever
23
Q

What is a delayed prescription?

A

Involves educating patients or parents about the likely viral nature of the sore throat and providing a prescription to be collected only if the symptoms worsen or do not improve in the next 2 – 3 days

24
Q

First line antibiotics for tonsilitis?

Alternative if allergic?

A
  1. Phenoxymethylpenicillin for a 10-day course
  2. Clarithromycin if penicillin allergy
25
Q

List 4 complications of Tonsilitis

A
  1. Peritonsillar abscess (quinsy)
  2. Otitis media
  3. Scarlet fever
  4. Rheumatic fever
  5. Post-streptococcal glomerulonephritis
  6. Post-streptococcal reactive arthritis
26
Q

What is Epiglottitis?

A

Inflammation and swelling of the epiglottis caused by infection

Life threatening emergency

27
Q

Most common causative organism of Epiglottitis

A

Haemophilus influenza type B

28
Q

In which specific patient group must we have the highest suspicion of Epiglottitis?

A

Unvaccinated children

Routine vaccination programs protect against haemophilus

29
Q

Presenting features suggesting Epiglottitis?

A
  1. Sore throat and stridor
  2. Drooling
  3. Tripod position
  4. Fever
  5. Difficulty or painful swallowing

Child may have a muffled voice or be scared and quiet. Keep a look out for signs of sepsis

30
Q

Characteristic X-ray sign in acute epiglottitis

A

Lateral xray of the neck shows “thumb sign” or “thumbprint sign”

Caused by the oedematous and swollen epiglottis

31
Q

Management of acute Epiglottitis

A
  1. Do NOT distress the patient - can prompt closure of the airway
  2. Alert paediatrician and anaesthetist (incase tracheostomy required)
  3. Secure the airway
  4. IV antibiotics (e.g. ceftriaxone)
  5. Steroids (i.e. dexamethasone)
32
Q

Common complication of Epiglottitis?

A

Epiglottic abscess

Also threatens the airway, treatment similar to epiglottitis
