Objectives: Pediatric Pneumonia With a focus on Community-Acquired Pneumonia. Discuss the different etiologies for both community and nosocomial pneumoniaList the common pathogens that are associated with both CAP and nosocomial pediatric pneumonia Demonstrate the different pathogens seen in different age groups for both community and nosocomial pneumonia. Discuss the prevalence of community acquired pneumonia (CAP) in the pediatric population.Discuss outpatient treatment considerations and 23

1. Pediatric Community-Acquired and Nosocomial Pneumonia
3. DefinitionCommunity acquired pneumonia An acute infection of lung parenchyma including alveolar spaces and interstitial tissue.
Pathogens gain access to the lungs by three routes.
Inhaled aerosolized particles
via the bloodstream
aspiration
The presence of fever, acute respiratory symptoms, plus the evidence of parenchymal infiltrates on chest x-ray.
4. PrevalenceCommunity acquired pneumonia Pneumonia is the leading cause of death in children throughout the world.
4 million children a year die from pneumonia worldwide.
In children < 5 the incidence is 34 to 40 cases per 1000 in Europe and North America.
The incidence is higher in childhood than at any other time of life.

16. SummaryCommunity acquired pneumonia The incidence of pneumonia is higher in children than in adults.
It is important to identify the age specific pathogens and treat empirically.
It is important to consider compliance issues such as taste when treating a pediatric patient.
