Pediatric Presentations Flashcards
What pathogen is associated with bronchiolitis?
RSV
What pathogen is associated with croup?
Parainfluenza
What pathogen is associated with exacerbations of asthma?
Rhinovirus
Prodrome of cold, hoarseness and barking cough, minimal to severe inspiratory stridor, not toxic appearing, stridor best heard over neck with clear lung fields, low grade fever, Steeple sign (subglotting narrowing on CXR)
Croup (viral) (laryngotracheobronchitis)
Prodrome of URI, hoarseness and barking, inspiratory stridor, toxic appearing, high grade fever, subglottic narrowing
Bacterial tracheitis (typically s. aureus)
What pathogen is associated with pertussis?
Bordatella pertussis or bordatella parpapertussis
GNRs
Coughing spells, post-tussive whooping, vomiting, no fever, elevated WBC, cough lasting more than 7-14 days
Pertussis
Edema, increased mucus secretion and eventual necrosis of small airways, rhinitis, cough, *tachypnea, wheezing and crackles
Bronchiolitis
Cough, grunting, chest pain, tachypnea, nasal flaring and retractions, cyanosis, dullness to percussion, decreased breath sounds, bronchial breath sounds, abrupt onset, high fever, toxic appearance
Bacterial pneumonia
Prominent URI symptoms, low grade or absent fever, diffuse findings or wheezes on exam, possible diffuse infiltrates
Viral pneumonia
Tachypnea, mild hypoxemia, lack of fever, wheezing, interstitial infiltrates
Atypical pneumonia - infancy (<3 mos) Chlamydia trachomatis (also look for conjunctivitis at 10 days)
Gradual onset, low grade fever, diffuse eam findings, diffuse infiltrates
Atypical pneumonia - older children (>5 yrs)
Mycoplasma
How long can an abnormal appearance on CXR continue in bacterial pneumonia?
6 weeks
When should CF be suspected in a child?
Recurrent episodes of cough, pneumonia, or sinusitis
Unexplained poor weight gain or FTT
Nasal polyps, rectal prolapse, hypochloremic alkalosis or FH of CF
What tests can be used to diagnose CF?
Immunoreactive trypsinogen (IRT) - pancreatic enzymes elevated in CF, used in the newborn screen
Sweat chloride test - gold standard - >60 is positive
DNA analysis to identify CTFR mutations
