Respiratory System Flashcards
The most common pathogen associated with common colds
Rhinoviruses
A viral illness in which patients complain of a scratchy throat, followed by nasal obsteuction and rhinorrhea with predominance of PMNs in the nasal secretions.
Common Cold
The most common complication of a cold is:
Otitis Media
The condition caused by this organism often has rapid progression noted with prominent sore throat, fever woth no cough.
Streptococcal Pharyngitis
Gold standard for diagnosing Strep Pharyngitis:
Throat Culture
True or False: Primary benefit of treatment of Strep Pharyngitis is the prevention of acute rheumatic fever
True
GABHS is still susceptible to this drug
Penicillin
GABHS is still susceptible to this drug
Penicillin
To eradicate streptococcal carriage ( Strep Pharyngitis), this drug can be given:
Clindamycin
These are more common in children younger than 3-4 y.o. associated with non-specific symptoms such as fever, irritability, decreased oral intake, drooling. On PE with bulging posterior pharyngeal wall
Retropharyngeal Abscess
This is caused by bacteri invasion through the capsule of the tonsils,leading to cellulitis and or abscess formation of the surrlunding tissiues. On PE there is asymmetric tonsillar bulge with displacement of the uvula
Peritonsillar Cellulitis or Abscess
This condition mostly affects children ages 3 months old to 5 years old and presents with barking cough, hoarseness and inspiratory stridor.
Croup (Laryngotracheobronchitis)
In radiographs, this shows subglottic narrowing (Steeple Sign)
Croup
This organism is the most commonly identified etiology of acute epiglottitis:
H. Influenza Type B
For vaccinated children, these organisms causes epiglottitis:
Strep (pyogenes and pneumoniae)
Staph aureus
This is a rapidly progressive disease with fever, sore throat, dyspnea and progressing respiratory obstruction. Patients are observed to have an hyperextended neck or in a tripod position with a wide open mouth sometimes also associated with droolong
Supraglottitis (Acute Epiglottitis)
Classic radiologic finding of a “thumb sign”
Epiglottitis
Diagnosis of this condition is via laryngoscopy showing a large, cherry red swollen epiglottitis
Epiglottitis
Rifampin prophylaxis (Epiglottitis):
<48 Months (Incompletely Immunized)
<12 Months (No primary vaccination series)
Immunocompromised child in the household
This condition is initially charcterized by an URTI with symptoms such as sore throat, cough and hoarseness which is usually out of proportion to the systemic manifestations.
Acute Infectious Laryngitis
This condition is initially charcterized by an URTI with symptoms such as sore throat, cough and hoarseness which is usually out of proportion to the systemic manifestations.
Acute Infectious Laryngitis
The principal area affected is the subglottic area.
Acute Infectious Laryngitis
This organism is the most commonly isolated pathogen for Bacterial Tracheitis:
S. Aureus
Usually follows a viral infection, may be considered as a bacterial complication of a viral disease characterized by brassy cough, high fever, appears to be in distress
Bacterial Tracheitis
