2.  The most common cause ofThe most common cause of cough inin
children is represented by airwayschildren is represented by airways
respiratory infection,respiratory infection, mostly concerning the
upper airway and of viral origin (URTI).
 A healthy child is expected to present with
3.8–8 infective episodes per year, vs. the
average of two episodes for an adult .

3. Cough associated with a single
infective episode may last from days
to weeks, with an average of 1–3
weeks , and it has been demonstrated
that 10% of children will be expected
to be still coughing after 4 weeks from
the beginning of the infection.

IFECTIONS
 Common cold
 Pharyngitis
 Sinusitis
 Ear infections

6. The common cold
 Short, mild and usually self-limiting illness.
 Children may have up to12 colds per year.
 200 types of viruses, the most common is
rhinovirus ( 40% ).

7. Clinical features of common cold:
 Rhinorrhea, sore throat,cough,fever and
malaise lasting up to 7 days and often
lingering mucopurlant nasal discharge.
 In infants cold may manifest as irritability,
snuffles and difficulty with feeding.
 Infants under 3 months of a age are
susceptible to LRTI.

8. Treatment of common cold
Echinacea, humidified air, nasal decongestants,
vitamin C and zinc have reported some
positive results but there insufficient data to
recommend any of these for treatment.

Arneil' Textbook of Pediatrcs, 715,2008

9. Acute sore throat

10. Pharyngitis
 Bacterial infectionBacterial infection
 Viral infection
 Streptococcus pyogenes – most serious type
 Scarlet fever
 Rheumatic fever
 Glomerulonephritis

11. Streptococcus pyogenesStreptococcus pyogenes
Group A is virulent
Streptolysins - toxin (hemolysins)
Erythrogenic – toxin
Toxins can act as superantigens
Over stimulate T cells
Tumor necrosis factor

12. ƄƄ Bacterial infection:Bacterial infection:
Group A beta-hemolytic Streptococcus
• Most common and important
• Commonly presents in children aged 5–6
• Fever, dry sore throat, cervical adenopathy,
dysphagia, and odynophagia
• The tonsils and pharyngeal mucosa are
erythematous and may be covered with
purulent exudate
• The tongue may also become red ("strawberry
tongue")
• Sequelae: acute rheumatic fever and
poststreptococcal glomerulonephritis

13. The surface antigens of group A streptococcus serve as
virulence factors.

15. Streptococcus infection causing inflammation of the throat
and tonsils.

16. Treatment of acute phryngitis
 Penicillin V 250 mg/dose for children and
500mg/dose for adolescents and adults.
 Amoxicillin; 750 mg once daily for10 days or
50 mg/kg/day for 6 days divided bid.
 A single IM injection of benzathine penicillin
(600,000U for children < 27 kg; 1,2 million U
for larger children and adults.
 Erythromycin 40 mg/kg in divided doses for
10 days.

17. Azithromycin offers convenience of once-
daily administration and shorter length of
therapy.
Cephalosporins appear to be as, good as or
better than penicillin, perhaps because these
drugs are more effective in eradicating
streptococcal carriage. Evidence is not
sufficient to recommend shorter courses of
cephalosporins for routine therapy at this time

28. Sinuses
 Sinuses are moist air spaces within the bones of
the face around the nose
 Human have 4 pairs of sinuses
 The ethmoid and the maxillary sinuses form in the
third to fourth gestational month
 The sphenoid sinuses are generally pneumatized
by 5 years of age
 the frontal sinuses appear at age 7 to 8 years but
are not completely developed until late
adolescence.

34. Sign and symptoms
 In pediatric patients, most URIs last 5-7 days.
By 10 days, the URI almost always improves.
Most rhinoviral infections improve within 7-10
days so the complaint of persistent or worsening
symptoms may indicate a developing bacterial
sinusitis.
Pediatric patients may complain of a daytime
cough and persistent nasal discharge.
Complaints of facial pain and headache are rare in
children.

35. The clinical diagnosis of Bacterial sinusitis is
based solely on history.
Persistent of symptoms of URI , including
nasal discharge and cough, for >10-14 days,
or temp 39 C and purulent discharge for 3-4
days

36. Chronic sinusitisChronic sinusitis
 CoughCough
Nasal discharge or nasal congestion lasting
more than 90 days

37. Physical examination
- Facial tenderness to palpation is present
- Nasal mucosa is inflammation, redness and
swelling
- Purulent secretions in the middle meatus
(highly predictive of maxillary sinusitis)
- Complete opacification of sinus on

42. Acute Otitis MediaAcute Otitis Media

43. . Otitis media is one of the most common
diagnosis made by pediatricians
 30-60% of children have had at least one
putative episode of AOM by age one.
 10-20% have had three or more.
 80% have had at least one episode by age
3 years.

44. Approximately 80-90% will have had
at least one episode of either AOM or
asymptomatic middle ear effusion in
the first year of life.

73. 2004AAP/AAFP Clinical Practice
Guideline on AOM
 Released March 2004
 Evidence-based clinical practice guideline:
 3461 articles initially identified; 760 reviewed
 Extensively peer-reviewed
 Scope: diagnosis and management of uncomplicated
AOM in children aged 2 m to 12 y
 Excludes children with:
 underlying conditions that predispose to AOM
 children with recurrence of AOM within 30 days of AOM
or underlying chronic OME

74. 2004AAP/AAFP Clinical Practice
Guideline on AOM: Conclusions II
1. To diagnose acute otitis media the clinician should confirm a history of
acute onset, identify signs of middle–ear effusion, and evaluate for the
presence of signs and symptoms of middle-ear inflammation
(Recommendation).
2. The management of AOM should include an assessment of pain. If pain is
present, the clinician should recommend treatment to reduce pain (Strong
Recommendation).
3A. Observation without use of antibacterial agents in a child with
uncomplicated AOM is an option for selected children based on diagnostic
certainty, age, illness severity, and assurance of follow-up (Option).
3B. If a decision is made to treat with an antibacterial agent, the clinician
should prescribe amoxicillin for most children. (Recommendation). When
amoxicillin is used, the dose should be 80–90 mg/kg/day (Option).

75. 2004AAP/AAFP Clinical Practice Guideline on
AOM: Conclusions II
4. If the patient fails to respond to the initial management option within
48–72 hours, the clinician must reassess the patient to confirm AOM
and exclude other causes of illness. If AOM is confirmed in the
patient initially managed with observation, the clinician should begin
antibacterial therapy. If the patient was initially managed with an
antibacterial agent(s), the clinician should change the antibacterial
agent(s) (Recommendation).
5. Clinicians should encourage the prevention of AOM through
reduction of risk factors (Recommendation).
6. There is insufficient evidence to make a recommendation regarding
the use of Complementary and Alternative Medicine (CAM) for AOM
(No Recommendation).
The recommendations in this guideline do not indicate an exclusive
course of treatment or serve as a standard of medical care.
Variations, taking into account individual circumstances, may be
appropriate.

antibiotics—because of parental pressure or
the lack of diagnostic accuracy—it is better
to limit the mistake to less expensive drugs

81. Drugs chosen for second-line treatment should be
effective against B lactamase- producing strains of H.
influenzae and M. catarrhalis
and against susceptible and most nonsusceptible
strains of S. pneumoniae. Only 3 drugs have been
shown clearly to meet that requirement: amoxicillin-
clavulanate, cefuroxime axetil, and intramuscular
ceftriaxone.
Kersshner J E,Otitis Media In:Nelson Textbook of Pediatrics, 2641,

82. Cefdinir was not available when the above
recommendations were made. However, clinical
Practice and efficacy with cefdinir suggest that it
deserves consideration as a second line agent as well,
with antibacterial spectrums similar to those
of cefuroxime axetil, and good rates of compliance' as
the medicationis quite palatable.

83. Conjunctivitis–otitis syndrome:
ß lactamase- producing H influenzae
tends to be the predominant organism, causing
both conjunctivitis and AOM.
High-dose amoxicillin–clavulanate (90
mg/kg/day), cefdinir or cefpodoxime would be
preferred choices.

84. Ambulatory pneumonia (‘‘walking
pneumonia’’ AND O M
As atypical pathogens (Chlamydia
pneumoni , Mycoplasma pneumoniae) are
such a common cause of milder pneumonias
in children ≥ 2 years of age, macrolides such
as azithromycin or clarithromycin are
preferred.

85. ImpetigoImpetigo

86. Impetigo or skin infection and AOM:
Typically, impetigo and skin infections are caused by
Staphylococcus aureus and only rarely by Streptococcus
pyogenes. Staphylococcus aureus in the
produces b lactamase, rendering amoxicillin useless.
Clinicians would be wiser to initiate treatment with a b
lactamase-stable antibiotic, such as amoxicillin-clavulanate,
cefdinir or even cefuroxime,
which possess activity against both methicillin-susceptible
Staphylococcus aureus and typical otopathogens.
Block S L. Arch Dis Child 2006;91:959–961.

87. Impetigo or skin infection and AOM:
Patients whose skin infection does
not respond in 24–28 h would then
additionally receive either clindamycin
or trimethoprim-sulfamethoxale
for presumptive methicillin-resistant
Staphylococcus aureus.
