mucosa

4. EPIDEMIOLOGY:
• Average in children : 6-7 colds /year
• Period of infectivity: few hours to 1-2 days after illness
appeared
• Mode of Transmission: through inhalation or droplet nuclei;
direct inoculation/contact
5. CLINICAL MANIFESTATION
• Symptoms of rhinorrhea and nasal obstruction are prominent
• Usual colds lasts about 1 week
• PE – swollen erythematous nasal turbinates
• A change in color or consistency of the secretions is common
during the course of illness and NOT indicative of sinusitis or
bacterial superinfections
6. CONDITIONS THAT MIMIC THE COMMON COLD
CONDITION DIFFERENTIATING FEATURES
Allergic Rhinitis Prominent itching and sneezing. Nasal Eosinophils
Foreign Body Unilateral, foul smelling D/C, bloody nasal secretion
Sinusitis Presence of fever, headache or facial pain, or periorbital
edema or persistence of rhinorrhea or cough for 14 days
Streptococcosis mucopurelent nasal discharge that excoriates
Congenital syndrome Persistent rhinorrhea with onset in the frst 3 months of life
Pertussis Onset of persistent / severe cough
7. DIAGNOSIS
• Routine laboratory studies- not helpful
• Nasal smear eosinophils- only if allergic rhinitis is suspected
• Viral viruses - generally not included; useful only when anti-
viral agent contemplated
8. COMPLICATIONS
• Otitis media – most common; 5-30% of children
• Sinusitis – 5-13% of cases
• Inappropriate use of antibiotics- important consequences of
antibiotic resistance of pathogenic respiratory bacteria; 30%
of MDs- prescribe antibiotic
9. TREATMENT
• Primarily symptomatic
• Antibiotics of no benefits
• Antiviral – specific for rhinovirus – not available
• Ribavirin for RSV- no role
• Oseltamivir/Zanamivir- modest effect on duration of influenza;
beneficial if started w/in 2 days of onset
10. TREATMENT:
1. NASAL OBSTRUCTION – topical adrenergic agents
(xylometazoline, oxymetazoline, phenyleprine; not approved
for <2 years old, prolonged use should be avoided to prevent
RHINITIS MEDICAMENTOSA.
- Oral adrenergic agents – less effective, associated with
CNS stimulation, hypertension and palpitation
11. 2. COUGH
- due to URT irritation associated with PND --> treatment
1st generation antihistamine--> helpful
- due to virus- induced reactive airway disease-->
bronchodilator treatment
- codeine
- dextromethorphan
- guiefeneisin
12. 3. RHINORRHEA
- 1st generation antihistamine- reduce it by 25-30%; effect
due to anticholinergic property
- 2nd generation antihistamine- no-sedating; no effect on
symptom
- Ipratropium Bromide –topical anticholinergic; not
associated with sedation; most common side effects:
nasal irritation and bleeding
- Vitamin C, guaifenesin, warm humidifier air, zinc,
echinacea
15. • Most important agents: viruses and GABHS
• Strictly refers to conditions in which principal involvement is
throat
• Strep pharyngitis- uncommon under 2-3 years, peak incidence
at early school years
• Mode of transmission: person to person contact through
airborne dissemination or indirectly through contaminated hands
17. • STREPTOCOCCAL PHARYNGITIS
- Rapid onset (2-5 days) with prominent sorethroat,
absence of cough or fever
- Red pharynx, enlarged tonsils with yellow, blood -tinged
exudates
- Petechiae/ donut lesions on the soft palate and posterior
pharynx; uvula red, stippled and swollen, enlarged and
tender CLAD
18.
19. 1. Throat Culture
2. Rapid test for GAS Ag
- high specificity so if (+), throat culture /sensitivity is
unnecessary
- less sensitive, so a (-) test must be confirmed by throat c/s
20. • Early antibiotic treatment hastens clinical recovery by 12-24
hours
• Primary benefit of treatment: prevention of Acute RF
• Antibiotics recommended even without c/s in:
- children with symptomatic pharyngitis and clinical a
positive rapid streptococcal Ag test
- clinical diagnosis of scarlet fever
- household contact with documented strep pharyngitis
- past history of Acute RF
-recent history of acute RF in family member
21. • GABHS remains universally susceptible to penicillin
- Pen V
- Amoxiciillin
• Alternative treatment
- erythromycin
- azithromycin
- 1st generation cephalosphorin
- clindamycin
22.
23. • Neck contains deeply located lymph nodes-
retropharyngeal/lateral pharyngeal nodes that drain upper
airway and digestive tracts
• Infection- usually an extension from a localized infection of the
oropharynx
• Etiology: 67% w/ history of recent ENT infection; can result
from penetrating trauma to the oropharynx; dental infection;
vertebral osteomyelitis
• Grp A hemolytic streptococci, oral anaerobes and S aureus-
most common pathogens
24. • Once infected, nodes progress to 3 stages:
cellulitis --> phlegmon --> abscess
26. • Lateral Pharyngeal: fever, dysphagia and a prominent bulge of
lateral pharyngeal wall w/ displacement of the tonsils
27. • I and D for culture and sensitivity for definitive treatment
• CT scan only useful but accurate only in 63%; soft tissue film –
increased width, air-fluid level in the retropharyngeal space
28. • Antibiotic with or w/out surgical drainage
- 3rd generation cephalosphorin + Sulbactam Ampicillin
or Clindamycin for anearobic coverage
- drainage if with respiratory distress or failure to
improve with IV antibiotics
31. • Caused by bacterial invasion through capsule of tonsils
• Typical patient – adolescent w/ recent history of ATP; group A
streptococcus and oral anaerobes- most common pathogens
32. • Sore throat, fever, trismus, dysphagia
• PE: asymmetric tonsillar bulge with displacement of the uvula
33. • Antibiotic against against GAS/anaerobe: surgical drainage
• Tonsillectomy :
- failure to improve within 24 hours of antibiotic therapy
and needle aspiration
- history of recurrent peritonsillar abscess/ recurrent
tonsillitis
- complications from peritonsillar
34.
35. • Maxillary and ethmoid – present at birth; ethmoidal
pneumotized, maxillary not until 4 years of age
• Frontal sinus : begin to develop by age 7-8 years old
• Sphenoid sinus: present by age 5 year of life
• Paranasal sinus: normally sterile, maintained by mucocilliary
system
• Typically follows a viral URTI
• Nose blowing- can generate sufficient force to propel nasal
secretions into nasal cavities
36. üEtiology: M. catarrhalis (20%), H. influenza(20%), S pneumonia
(30%)
üMay occur at any age
üPredisposing conditions: viral URTI, allergic rhinitis, cigarette
smoke exposure
üPresence of URTI ( nasal discharge and cough) > 10- 14 days
without improvement
üSevere respiratory symptoms, including temperature of at least
39o C
üPurulent nasal discharge x 3-4 consecutive days
37. Clinical Manifestations
Nonspecific: nasal congestion/ purulent nasal discharge, fever,
cough
Less common: halitosis, decrease sense of smell and periorbital
edema
Rare: headache and facial pain
Additional/s: maxillary tooth discomfort, pain exacerbated by
bending forward, hyposmia
38. Physical Examination
- mild erythema and swelling of nasal mucosa with purulent nasal
discharge
- Sinus tenderness in adolescent
Diagnosis
- Transillumination of sinus cavity
- Sinus plain films and CT scan- can confirm presence of sinus
inflammation
- Sinus aspirate culture- the only accurate method for diagnosis
39. Treatment
- Amoxicillin
- Amoxicillin- clavulanic acid
- Second generation cephalosphorins if allergic with penicillin
- Treatment failure with amoxicillin after 72 hours: use
azithromycin, levofloxacin
- Decongestants, mucolytics, intranasal corticosteroids
- Saline nasal wash/ spray- liquefy secretions
