1. Course Topic Overview: Pediatric Infections
Definitions
Pediatric infections encompass acute and chronic infectious diseases affecting
neonates, infants, children, and adolescents across upper and lower respiratory
tracts, skin, soft tissues, gastrointestinal tracts, and systemic organ systems.
Pathophysiology
Pediatric host responses are influenced by immature mucosal barriers,
maternally acquired antibody waning, and developing cellular/humoral immunity.
Pathogens (viral, bacterial, fungal, or parasitic) invade host tissues, inciting local
inflammatory cascades, systemic cytokine release, pyrogen-mediated
hypothalamic resetting (fever), and site-specific tissue damage (e.g., alveolar
exudates in pneumonia, meningeal inflammation in meningitis).
Risk Factors
● Prematurity and low birth weight
● Immunization gaps or delays
● Attendance at childcare/daycare facilities
● Household crowding and environmental tobacco smoke exposure
● Anatomical abnormalities (e.g., vesicoureteral reflux, eustachian tube
dysfunction)
● Immunocompromising conditions
,Clinical Manifestations
Variable by age and pathogen. Neonates often display non-specific signs
(temperature instability, poor feeding, lethargy). Older infants and children
manifest localized findings (cough, wheezing, otalgia, odynophagia, rash,
diarrhea) alongside systemic signs (fever, irritability, lymphadenopathy).
Assessment Findings
● General: Appearance (toxic vs. non-toxic, level of alertness via Yale
Observation Scale), perfusion, hydration status.
● EENT: Erythematous bulging tympanic membrane with decreased mobility;
tonsillar exudates, palatal petechiae, anterior cervical adenopathy.
● Respiratory: Tachypnea, nasal flaring, intercostal/subcostal retractions,
grunting, diminished breath sounds, crackles, or wheezes.
● Dermatological: Exanthems (morbilliform, vesicular, purpuric,
scarlatiniform), skin breakdown, or localized cellulitis.
Differential Diagnoses
● Viral upper respiratory infections vs. bacterial pharyngitis/otitis media
● Bronchiolitis vs. asthma exacerbation vs. bacterial pneumonia
● Roseola infantum vs. measles vs. scarlet fever
● Viral gastroenteritis vs. bacterial enterocolitis (surgical acute abdomen)
Diagnostic Testing
● Rapid Antigen Detection Tests (RADT) and throat cultures
● Complete Blood Count (CBC) with differential, blood cultures
● Inflammatory markers (ESR, CRP, Procalcitonin)
● Rapid multiplex PCR panels (respiratory/gastrointestinal)
● Chest radiography, urinalysis, and urine culture via catheterization in febrile
infants
Evidence-Based Management
Guided by national clinical practice guidelines (e.g., AAP, CDC). Strives to
minimize inappropriate antimicrobial stewardship while ensuring aggressive
coverage for invasive bacterial infections.
Pharmacological Interventions
, ● Antibiotics: Amoxicillin (first-line for AOM/strep), Azithromycin,
Ceftriaxone, Cefdinir.
● Antipyretics/Analgesics: Acetaminophen and Ibuprofen (contraindicated
in infants under 6 months).
● Supportive Agents: Saline nasal drops, oral rehydration solutions. Avoid
cough/cold medications in young children.
Non-Pharmacological Interventions
● Humidified air/cool-mist vaporization
● Adequate fluid intake management (enteral vs. parenteral hydration)
● Nasal bulb suctioning prior to feeds
Patient Education
● Completion of full antibiotic courses even after symptom resolution
● Recognition of toxic signs and red flags
● Fever management guidance (hydration and comfort measures rather than
alternating antipyretics aggressively)
● Adherence to the childhood immunization schedule
Follow-Up Care
● Re-evaluation if symptoms worsen or fail to improve within 48–72 hours of
antimicrobial therapy
● Re-inspection of tympanic membranes after treatment for recurrent AOM
● Verification of resolved hydration status and school/daycare clearance

2. Multiple-Choice Questions (1–30)
Question 1
A 4-week-old male infant is brought to the primary care clinic by his parents with
a 1-day history of poor feeding, irritability, and a rectal temperature of 38.3°C
(101.0°F). Physical examination reveals an otherwise active infant with normal
fontanels, clear lungs, and no focal source of infection. Which of the following is
the most appropriate, evidence-based management strategy for this neonate?
● A. Discharge home with supportive care, maternal education, and
instructions to return if fever persists beyond 48 hours.
