    Study Notes

    Rhinitis

    • Caused by human rhinovirus (HRV)
    • Affects all ages, but more common in children
    • Transmission via nose, eyes, and mouth
    • Symptoms are self-limiting
    • Characterized by nasal discharge and obstruction, sneezing, and coughing

    Sinusitis

    • High attack rate
    • Primarily viral, though bacterial (Streptococcus pneumoniae) infection is also possible
    • Symptoms include purulent rhinorrhea and pale blue turbinates, along with facial or dental pain, periorbital edema, and tenderness in sinuses.

    Pharyngitis

    • Adenovirus is the main cause in adults
    • Also caused by streptococcus, or other viruses.
    • Symptoms include sore throat, myalgia, and tonsillar exudate
    • Can be viral or bacterial, hard to distinguish clinically between the two

    Diphtheria

    • Severe pharyngitis, caused by Corynebacterium diphtheriae
    • Toxin causes hemorrhagic and necrotic lesions in various organs
    • Characterized by a gray pseudomembrane on the throat

    Epiglottitis

    • Primarily affects infants and young children
    • Caused by Haemophilus influenzae type b
    • Causes blockage of the airway
    • Symptoms evolve quickly with fever, sore throat, and difficulty swallowing

    Bronchitis

    • Common in children
    • Caused by parainfluenza viruses
    • Symptoms include rhinitis, hoarseness, dyspnea, and a barking cough
    • Diagnosis often supported by X-ray findings

    Bronchiolitis

    • Primarily in premature infants
    • Caused by Respiratory Syncytial Virus (RSV)
    • Peak incidence in the premature stage
    • Often co-exists with bronchitis or COPD

    Pertussis (Whooping Cough)

    • Caused by Bordetella pertussis
    • Toxins damage cilia, resulting in sticky mucus
    • Characterized by involuntary, uncontrollable coughing fits
    • Diagnosed via clinical presentation and possibly lab confirmation

    Influenza

    • Major respiratory tract infection
    • Caused by influenza virus
    • Demonstrates antigen drift and shift
    • Symptoms include fever, body aches, sore throat, and cough
    • High impact on lower respiratory tract infections

    Pneumonia

    • Multiple etiologies (viral, bacterial, fungal)
    • Symptoms vary based on causative agent
    • Treatment varies based on the causative agent, and whether or not a cell wall is present
    • X-ray findings are often suggestive of the underlying cause

    Tuberculosis

    • Atypical, Mycobacterium infection
    • Transmission primarily through inhalation

    Other Pneumonia Agents

    • Causative agents include Pneumocystis pneumonia (PCP), Legionella pneumophila (severe pneumonia), Haemophilus influenzae type b, Streptococcus pneumonia, Klebsiella pneumoniae, Pseudomonas, and Staphylococcus.
    • The specific causative agent contributes to the type of pneumonia and treatment procedures needed.
