Paediatric ENT Flashcards

1
Q

Why is ET dysfunction and its complications (AOM, Glue ear…) more common in the paediatric population?

A

1) ET in children is shorter and straighter => tighter
2) Recurrent URTIs => Increased secretions and congestion
3) Adenoid Hypertrophy => Less space => exacerbation. Dissolves in adults => resolved

Q

Adenoids are lymphoid tissue located at the superior posterior wall of the nasopharynx. It typically increases in size until 7 years old before starting to shrink.
What paediatric conditions may arise from adenoid hypertrophy?
If adenoids are found to be the cause or an exacerbating factor to any of these conditions, what is the tx?

A

As it is a lymphoid tissue, any infection may lead to its hypertrophy => obstruction

OSA (snoring, sweaty sleeps..)
ET dysfunction => Retracted TM, Glue Ear, Recurrent OM

Tx: Adenoidectomy may be escalated to adenotonsillectomy

Q

A mother in the post-natal ward complains that their neonate is unable to feed. She says that they latch on well but then it is just a constant crying then blue.
What is the most likely diagnosis? Why?
How will you confirm your diagnosis and manage the patient?
What syndrome is this associated with?

A

Inability to feed + Cyclical crying + cyanosis. Infants are obligate nose breathers for the first 3 months of life and hence with this presentation, most likely diagnosis = Choanal atresia

Diagnosis and tx:
1) Observe mucus/fogging of fogging-metal spatula
2) Pass NG tube -> secure with nasopharyngeal tube
If still unable then
3) Fiberoptic scope
4) CT head

Q

Similar to Sinusitis, A viral infection typically precedes a bacterial superinfection in Acute Tonsillitis.
What are the viral and bacterial pathogens involved?
How could you differentiate the presentation of bacterial vs viral tonsillitis?
What is the workup of Acute Tonsillitis
How would you treat acute tonsillitis?
What are the complications of acute tonsillitis?

A

What are the viral and bacterial pathogens involved?
Viral: Adenovirus, Parainfluenza virus
Bacterial: S.Pneumoniae, H.Influenzae, and M. Catarrhalis (same as AOM and Sinusitis)

How could you differentiate the presentation of bacterial vs viral tonsillitis?
Viral: Mild pyrexia, sore throat, adenoid hypertrophy - typically resolves <48hrs
Bacterial: High-grade pyrexia, severe sore throat, adenoid hypertrophy !Lasting >48 hours

What is the workup of Acute Tonsillitis:
In all cases same cuz of risk of infectious mononucleosis
=> Full hx and examination (check for splenomegaly)
=> Throat culture + FBC (increased UCC mostly neutrophils vs lymphocytes) + procalcitonin + CRP…
=> Monospot test + LFTs

How would you treat acute tonsillitis?
Viral: Antipyretics, cough suppressants, !hydration
Bacterial (>48 hours): Co-amoxiclav (note contains amoxicillin => infectious mononucleosis) + viral tx + analgesia
Surgical: (if indications met) Tonsillectomy/Adenotonsillectomy

What are the complications of acute tonsillitis?
Suppurative: Quinsy (Peritonsilar abscess)
Non-suppurative: Post-strep => rheumatic fever/glomerulonephritis + OSA

Q

What are the indications for a tonsillectomy?

A

1) Recurrent disabling sore throat due to acute tonsillitis
a) 7 or more in preceding year
b) 5 or more in preceding 2 years
c) 3 or more in preceding 3 years
2) Asymmetric Tonsils (to rule out malignancy)
3) Recurrent peritonsillar abscess
4) Chronic Tonsillitis

Q

Parents always ask if removing the tonsils will have an effect on their child’s immunity. There is no evidence to prove that => it has no effect on that. With that, what are the actual complications of tonsillectomy?

Bonus (no effect on grade): What exam findings are found post-tonsillectomy?

A

Palatal dysfunction
Voice changes/hoarsness
Velopharyngeal insufficiency (port separating nasal cavity from pharynx. its insufficiency leads to air leak during speaking)
Typical: Scarring dehydration, hemorrhage, anesthetic risk, DVT…(not in peds)

Post-tonsillectomy:
Eschar (dead tissue that sloughs off)
Foul smelling
palatal oedema

Q

How would you differentiate glandular fever from typical acute tonsillitis when seeing a patient with enlarged palatine tonsils?

A

FBC increased WCC with increased leukocytes (vs neutrophils)
Monospot test +vs (vs -ve)
Abnormal LFTs (vs normal)
Rash w/Ampicillin
!!Hepatosplenomegaly on Exam
Grey Slough on grossly enlarged tonsils (picture)

Lymphadenopathy is incorrect as other viruses may cause that (correct if differentiating vs bacterial in general)

Q

What is Glandular fever/infectious mononucleosis?
What is the typical presentation of a patient with Infectious mononucleosis including exam findings)?
What is your workup for this patient?
How would you manage this patient?

A

Glandular fever is a group of symptoms used to describe a patient with symptoms of EBV infection. It is exacerbated by ampicillin (or amoxicillin or coamoxiclav) which leads to a large maculopapular rash throughout the body (little teaching note)

Acute sore throat and fever with acute tonsillitis (pain, pyrexia…)
Cervical lymphadenopathy!
Grossly enlarged tonsils with grey slough!
Maculopapular Rash with ampicillin!
!Hepatosplenomegaly on exam?

Workup:
Throat culture + FBC w differentials showing leukocytosis with neutrophils vs lymphocytes
Must rule out EBV via Monospot test
LFTs (raised in infectious mononucleosis)0

Management: Supportive: hydration, antipyretics, analgesic
Honors: Avoid contact sports for 4-6 weeks to avoid ruptured spleen/liver (from hepatosplenomegaly)

17
Q

What is seen in this image. Describe it
Give 2 differentials

A

It is a large maculopapular throughout the back of the patient.
This may be consistent with infectious mononucleosis or Rubella infection

18
Q

You are asked to examine this patient. Describe what you see and your most likely diagnosis.
What is the typical presentation and clinical features?
how would you workup this patient
How would you manage this patient?

A

This is oral cavity of a patient presenting with acute tonsillitis. The tongue is depressed with a tongue depressor and there is a clear shift to of the uvula to the left (patient’s) as there is clear enlargement of the right tonsil. This finding is consistent with a peritonsillar abscess or Quinsy

Presentation: Severe !!unilateral sore throat, dysphagia, and odynophagia
Clinical features: Trismus, High grade pyrexia, Hot potato voice

Workup:
=> Full hx and examination (check for splenomegaly)
=> Throat culture + FBC (increased UCC mostly neutrophils vs lymphocytes) + procalcitonin + CRP…
=> Monospot test + LFTs (dont forget to rule out EBV)

Tx: (surgical emergency => ABCDE)
Medical: IV Antibiotics (amox - once confirmed not EBV)
Surgical: Draingage +/- Tonsillectomy (it is an indication by itself even)

19
Q

Placeholder for OSA powerpoint:
How would you manage a patient with OSA?

A

Overnight oximetry or cardiopulmonary/full polysomnography
tx: Conservative: Weight loss, dietitian referral, allergens at home (dust, pets, dolls, carpet)
Surgical: Adenotonsillectomy

20
Q

What is the most common congenital (1) and acquired causes (2) of stridor in the paediatric population

On first glance of a child, what clinical feature would lead you to directly suspect airway obstruction/stridor?

A

Congenital: Most common cause of chronic stridor - Laryngomalacia (others include congenital vocal cord paralysis, subglottic stenosis, laryngeal web)

Acquired: Croup (laryngotracheitis), Epiglottitis, Foreign body

Tripod positioning, leaning forward

21
Q

What is laryngomalacia?
What is it the most common cause of?
What type of stridor is exhibited?
How would you manage a patient with laryngomalacia?

A

Congenital softening of tissues in larynx => floppy => obstruction => chronic stridor (most common cause) => cyanotic episodes in infants

Supraglottic tissues are softening => Inspiratory stridor

Laryngomalacia is typically self-resolving within 2 yrs
If recurrent => Supraglottoplasty

22
Q

What is the most common pathogen causing Epiglottitis?
What is the typical presentation of a patient with epiglottitis?
When examining or treating a patient with epiglottitis what is important to keep in mind?
How would you manage your patient?

A

H. Influenzae (now rare cuz of vaccine)

Acutely unwell, febrile child in tripod position, leaning forwards => Drooling, wont cough or swallow (dysphagia), agitated.

When examining or treating a patient with epiglottitis (esp children), do not irritate with tongue depressor or IV lines until sedated or secured airway.

It is an emergency => inform ENT and anesthetics to secure airway
+ IV antibiotics (cefotaxime, ceftriaxone)
