Acute Laryngotracheobronchitis (Croup)
Definition
• inflammation of tissues in subglottic space ± tracheobronchial tree
• swelling of mucosal lining associated with thick, viscous, mucopurulent exudate which compromises
upper airway (subglottic space is narrowest portion of upper airway)
• normal function of ciliated mucous membrane impaired
Etiology
• viral:parainfluenzae1 (most common), 11,111, influenza A and B, RSV
Clinical Features
• age: 6 mo-3 yr
• preceded by URT'
I symptoms
• generally occurs at night
• biphasic stridor and croupy cough (loud,sea-lion bark)
• appear less toxic than epiglottitis
• supraglottic area normal
• rule out foreign body and subglottic stenosis
• “steeple-sign"on AP x-ray of neck
• if recurrent croup, think subglottic stenosis
Signs of Croup
The 3Ss
St ridor
Subglottic swelling
Seal bark cough
Treatment
• racemic epinephrine via metered-dose inhaler ql
-2 h PRN (if severe croup, >2 Westley Croup Score)
• systemic corticosteroids (e.g. dexamethasone 0.5 mg/kg, prednisone)
• adequate hydration
• close observation for 3-4 h
• positive pressure ventilation, nasal trumpet,laryngeal mask airway, intubation ifsevere (use smaller
endotracheal tube than expected for age)
• hospitalize if poor response to steroids after 4 h and persistent stridor at rest
• consider alternate diagnosis if poor response to therapy (e.g.bacterial tracheitis)
• if recurrent episodes of croup-like symptoms, consider bronchoscopy for definitive diagnosis
Acute Epiglottitis
<8>
Definition
• acute inflammation causing swelling ofsupraglottic structures of the larynx without involvement of
vocal cords Acute epiglottitisis a medical emergency
Etiology
• H. influenzae type B
• relatively uncommon condition due to H. influenzae type B vaccine
• common causes now include S
'
, pneumoniae and S. aureus
When managing epiglottitis,it is
important not to agitate the child,asthis Clinical Features may precipitate complete obstruction
• any age, most commonly 1-4 yr
• rapid onset
• toxic-looking,fever, anorexia, restlessness
• cyanotic/pale, inspiratory stridor,slow breathing, lungs clear with decreased air entry
• prefers sitting up ("tripod" posture), open mouth, drooling, tongue protruding,sore throat, dysphagia Thumb sign: cherry-shaped epiglottic
swelling with loss of the normal air
space of the vallecula seen on lateral
Investigations and Management neck radiograph
• examining the throat may lead to potential laryngospasm and airway compromise; ensure an
anesthesiologist/otolaryngologist is present and make preparationsfor intubation or tracheotomy
prior to any manipulation
• WBC (elevated), blood, and pharyngeal cultures after intubation
• lateral neck radiograph (only done if patient stable) shows "thumb sign"
Treatment
• secure airway
• IV access with hydration
• antibiotics:IV cefuroxime, cefotaxime,or ceftriaxone (10-14 d course should be completed)
• moist air
• extubate when leak around tube occurs and afebrile
• watch for meningitis

Subglottic Stenosis
Congenital
• diameter ofsubglottis <4 mm in neonate (due to thickening of soft tissue of subglottic space or
maldevelopment of cricoid cartilage), orsmaller than average size for age as determined by MyerCotton grading system
Acquired
• following prolonged, repeated,or traumatic intubation
most commonly due to endotracheal intubation; nasal intubation is less traumatic and preferred
in long-term intubation, as it puts less pressure on the subglottis (tube sits at different orientation)
and there is less movement
subglottic stenosis is related to duration of intubation and endotracheal tube size resulting in
pressure necrosis and subsequent scar formation
• can also be due to foreign body, infection (e.g. TB, diphtheria,syphilis), or chemical irritation
Clinical Features
• biphasic stridor
• respiratory distress
• recurrent/prolonged croup
Diagnosis
• rigid laryngoscopy and bronchoscopy
Treatment
• if soft stenosis:diside tissue with knife or laser,dilate with balloon ± steroids
• if firm stenosis:laryngotracheoplasty
Laryngomalacia
Definition
• short aryepiglottic folds,omega-shaped epiglottis, redundant mucosa over arytenoids
• caused by indrawing ofsupraglottis on inspiration, leading to breathing against closed glottis, causing
laryngopharyngeal reflux of acid
Clinical Features
• high-pitched inspiratory stridor at 1-2 wk
• stridor is constant or intermittent and more pronounced when supine or following URTI
• usually mild, but can be associated with cyanosis or feeding difficulties when severe, leading to failure
to thrive
Laryngomalada isthe most common
cause of stridor in infants
Treatment
• observation ± proton pump inhibitor (to break the acid reflux cycle that leads to edema and worse
airway obstruction) is usually sufficient, assymptomsspontaneously subside by 12-18 mo in >90% of
cases
• if severe, division of the aryepiglottic folds (supraglottoplasty) provides relief
Foreign Body
Ingested
• usually stuck at cricopharyngcus muscle
• coins, toys, batteries (emergency)
• presents with drooling, dysphagia,stridor if very large
Aspirated
• usually stuck at right main bronchus
• peanuts, carrot, apple core, popcorn, balloons
• presentation
stridor if lodged in trachea (beware of the silent child as there may be complete obstruction)
unilateral “asthma” if bronchial, therefore often misdiagnosed as asthma
if completely occluded airway:cough,lobar pneumonia, atelectasis, mediastinalshift,
pneumothorax, death
Diagnosis and Treatment
• sudden onset, not necessarily febrile or elevated WBC
• any patient with suspected foreign body should be kept NPO immediately
• older patient:inspiratory-expiratory'chest x-ray (if patient isstable)
• younger patient:right and left decubitus chest x-rays.Lack of lung deflation while resting on
dependentside suggests foreign body blocking bronchus
• bronchoscopy or esophagoscopy with removal
Foreign body inhalation is the most
common cause of accidental death In
children
Button batteries MUST be ruled out as a
foreign body (vs. coins) asthey are lethal
and can erode through the esophagus.
Batteries have a halo sign around the
rim on AP x-ray and a step deformity on

duration.Mean symptoms scores over Irom d 6 14 were 1.61in the 5 d group and 1.34 in the 10 d group.
Conclusions:10 d of amoxlcillln-clavulanate had more favourable outcomes and no increase in adverse events or antimicrobial
resistance compared to a 5 d course in children ages 6mo-2 yr.
Title:Meet olAntimicrobial Treatment of Acute Otitis Media on the Daily Disappearance on Middle Tar Illusion
Purpose:To study the effect of antimicrobial treatment on the duration olmiddle ear effusion|MTE) and hearing impairment.
Methods:Children were assigned to either have 40mg/kg of amoxicillin-clavulanale or a placebo miiture for 7 d.The primary
outcome measure was time till disappearance of MET.
Results:MEE disappeared 2 wk earlier in the antimicrobial group,than in the placebo group (2.7 wk vs.4.7 wk,respectively).
Conclusions:Treatment with amoxicillin-clavulanale reduced the duration of middle ear effusion compared toplacebo in children
vrith acute otitis media.

NEJM 2015:373(6):521-9 Title:Elective versus Therapeutic Neck Dissection n Node-Negative Oral Cancer
Purpose:To evaluate survival after elective neck dissection vs.therapeutic neck dissection in patients withlateraliied stage 11 or
12 oval squamous- cell carcinomas.
Methods: Aprospedive,randomited,controlled trial that evaluated survival after elective node dissection vs.therapeutic node
dissection.Overall survival and disease-free survival were used asprimary and secondary endpoints,respectively.
Results:At 3 yr.elective node dissection resultedinmore survival (80%).than therapeutic neck dissection (67.5%).As well,at 3
yt. elective node dissection patients had a higher rate of disease free survival compared lo those in the therapeutic surgery group
(69.5% vs.45.9%).
Conclusions:Among patients with early-stage OSCC.electiveneck dissection resulted inhigher rates of overall and disease-free
survival.
NEJM 2016; 374:1444-1454 Title:PET-CT Surveillance versus Neck Oissection in Advanced Head and Neck Cancer
Purpose:To compare the usefulness of planned neck dissection versus PET-CT-guided surveillance in patients withnodal stage N2
or N3 SCC.
Methods:Patients with N2 or N3 neck disease were randomly assigned to either a neck dissection(planned surgery group) or PETCT 12 weeks after chemoradiotherapy completion (surveillance group).The primary endpoint was overallsurvival.
Results:The 2 yr survival rate was 84.9% (95% Cl.80.7 to 89.1) in the surveillance group and 81.5% (95% Cl.76.9 to 86.3) in the
surgery group. The hazard ratio slightly favored PET-CT- guided surveillance and indicated noninferiority (upper boundary of the
95% Cl lor the hazard ratio.- 1.50;P‘
0.004).
Conclusions: PET- CT-guided surveillance is noninferior to planned neck dissection for overall survival in N2 or N3 SCC of Ihe head
and neck.
NEJM 2016: 375:1856 -1867 Title:Nivolumab for Recurrent Squamous-Cell Carcinoma ol the Head and Neck
Purpose: To compare the overall survival of patients with plalinum-refiaclory SCC of the head and neck treated with nivolumab
versus standard therapy.
Methods:Patients with recurrent SCC of the head and neck and disease progression within 6 mo after platinum-based
chemotherapy received either nivolumab or standard systemic therapy (methotrexate,docetaxel.or celuximab).The primary
endpoint was overall survival.
Results:Median overall survival was 7.5 mo (95%Cl.5.5 to 9.1)in the nivolumab group compared to 5.1mo (95% Cl,4.0 to 6.0) in
the standard therapy group.Survival is significantly longer with nivolumab (hazard ratio for death.0.70:97.73% Cl.0.51 to 0.96:
P-0.01).
Conclusions:Treatment withnivolumab resulted inlonger overall survival than treatment with standard therapy in platinumrefractory.recurrent squamous-cell carcinoma of the head and neck.

Title:Effectiveness ol Adenotonsillectomy vs.Watchful Wailing in Young Children Willi Mild to ModerateObstructive Sleep Apnea:
A Randomized Clinical Trial
Purpose: To determine whether adcnolonsillcclomy is more effective than watchful wailing for treatinghealthy children with mild
lo moderate 0SA.
Methods: 60 children ages 2 to 4 with mildlo moderate 0SA were randomized to cither adonotonsilledomy or watchlul walling.
Ihe primary outcome was Ihe difference inmean obstructive apnea hypopnea index (0AHI) score change between the two gioups.
Results:Both gioups had a reduced mean 0AHI score with a small intergroup difference (-1.0:95% Cl.-2.4 to 0.5).Children with
moderate 0SA showed a meaningful intergroup differencein mean 0AHI score change,favouring adenotonsilledomy (-3.1;95% Cl,
-5.71o -0.5).
Conclusions:Otherwise healthy children ages 2-4 withmild 0SA may benefit from watchful waiting,while children with moderate
OSA should beconsidered for surgical treatment.
Title:A Randomized Trial of Adenotonsilledomyfor ChildhoodSleep Apnea
Purpose:To investigate the benefits of adenotonsilledomy vs.supportive care on children withobstructive sleep apnea.
Methods:Children ages 5-9 yr,with obstructive sleep apnea syndrome were randomized to adenotonsilledomy or a strategy of
watchful waiting.Polysomnogiaphic,cognitive,behavioural,and health outcomes were assessed at baseline and again at 7 mo.
Results:Attention and executive function scores from baseline did not change significantly in theadcnolonsilledomy group vs.
the watchful waiting group (7.1x13.9 vs.5.1r13.4.respectively).Signilican!differences frombaseline in behavioural,and quality
of life were found in Ihe adenotonsilledomy group. Normalization olpolysomnogruphic findings were foundin more of Ihe
adenotonsilledomy than Ihe watchful waiting group (79% vs. 46%).
Conclusions:Surgical treatment for obstructive slcepapnea in children ages 5-9 did not significantly improve attention or
executive function but didimprove behaviour,quality of life,and polysomnogiaphic findings compared to watchlul waiting.
