Q

Infection rates: respiratory

A
  • infants < 3 mo: lower due to maternal antibodies
  • 3-6 mo: rate increases due to maternal antibodies decrease, own antibodies begins
  • toddler/preschool: viral infection rate remains high (exposure)

Q

influences to the response to respiratory tract infections

A
  • diameter of airway is smaller in young children
  • distance between structures is shorter causing organisms to move down respiratory tract quicker
  • shorter and open eustachian tube allows easy access of pathogens to middle ear

A

a chronic inflammatory disease of the airways characterized by:

  • airway obstruction
  • bronchial hyper-responsiveness
  • underlying inflammation
48
Q

hyperreactivity: asthma

A

airway (bronchial) smooth muscle contracts in response to irritants or allergens
- smoke, pollen, mold, dust, exercise, emotions, changes in weather, roaches, air pollution, colds, animals, foods, etc.
Made worse by many of the pro-inflammatory markers (mast cells, macrophages, etc…)

49
Q

obstruction: asthma

A
  • swelling/inflammation
  • mucus hyper-secretion and mucus plugging
  • spasm of the smooth muscle of the bronchi and bronchioles
  • airway remodeling which may include structural changes to the airway, i.e. thickening of the muscle, fibrosis
  • leads to air-trapping
50
Q

etiology: asthma

A
  • atopy: the genetic predisposition for the development of immunoglobulin E
  • viral respiratory infections: are one of the most important causes of asthma exacerbation, may also contribute to the development of asthma
  • genetics
51
Q

s/s: asthma

A
  • wheezing
  • prolonged expiratory phase
  • coughing
  • chest tightness
  • SOB
  • retractions
  • may progress to cyanosis
  • nasal flaring
52
Q

wheezing: asthma

A
  • a musical, high pitched sound caused by turbulent airflow
  • caused by air going through a narrow opening
  • can be “end-expiratory” or occur any time in respiratory cycle
  • diminished breath sounds during an asthma exacerbation= medical emergency
  • can go quickly from respiratory arrest to cardiac arrest
53
Q

cough: asthma

A
  • hacking, dry, nonproductive; can become rattling and productive
  • caused by stimulation of mechanical and chemical receptors in the airway
  • hallmarks of asthma is “night cough”
  • also consider asthma if cough recurs seasonally, or if it occurs as a response to specific exposures
54
Q

pulmonary function test: asthma

A
  • measures forced air expiration to look for signs of obstruction and reversibility
  • FVC is forced vital capacity, total amt of air that can be exhaled after maximal inspiration
  • FEV1 is fev in 1 second (reduced in asthma)
55
Q

assessing control: asthma

A
ongoing (q1-6m)
based on:
- symptoms
- nighttime awakenings
- interference with normal activity
- SABA use for symptoms control
- Lung function
classifications of control: well, not well, very poorly controlled
56
Q

exercise induced bronchospasm

A
  • exercise may be the only precipitant of asthma symptoms for some patients
  • exercise can be a trigger in children with a h/o asthma
  • EIB usually occurs during or minutes after vigorous activity, reaches its peak 5-10 minutes after stopping the activity
  • diagnosed with an exercise challenge test
  • inhaled beta2 agonists will prevent EIB in more than 80% patients. use SABA shortly before exercise. a warm up period may reduce the degree.
57
Q

short-acting B-2 agonist (SABA)

A
  • Albuterol/Xopenex
  • inhaled MDI (pump) or nebulizer (infants)
  • MDI must use spacer

  • for acute relief of symptoms, rapid onset, short duration (3-4h)
58
Q

Long-acting B-2 agonist (LABA)

A
  • Salmeterol/Formoterol
  • for long-term control
  • Must be used with an ICS
  • slower onset, long duration (12h)
  • not “rescue”
59
Q

Inhaled corticosteroids: asthma

A
  • Budesonide/Fluticasone
  • Anti-inflammatory drugs used at lowest possible dose, used long term to control symptoms and reduce bronchial hyper responsiveness
  • can lose 1-2 inches of adult height
60
Q

Systemic corticosteroids: asthma

A
  • oral or IV anti-inflammatory
  • for acute exacerbation not improving on albuterol alone
  • 3-10d course typical

Tetralogy of Fallot

A
typically 4 defects:
- VSD
- pulmonary stenosis
- overriding aorta
- RV hypertrophy
Clinical presentation
- "pink tet": pink at birth followed by some cyanosis (but not always)
- cyanotic tet
Treatment
- open heart surgery: palliative shunt to increase pulmonary blood flow, complete repair
88
Q

Digoxin

A
  • weigh risk vs. benefit
  • focus on bradycardia and hyperkalemia
  • consistent administration: 1 hr before or 2 hrs after meals (absorbs better on empty stomach)
  • IV: administer over 5-10min
  • do not administer if HR <70 in children
  • maintain potassium levels: 1/2 banana per day
89
Q

Lasix

A
  • teach parents about I/O
  • pay attention to orthostatic hypotension, electrolyte disturbances, dehydration
  • administration: may be administered with food or milk to decrease GI distress
  • hearing evaluation if hx high dosages
90
Q

Acquired heart diseases

A
  • infective endocarditis
  • Kawasaki disease
  • rheumatic fever
  • hyperlipidemia
  • arrhythmias
  • pulmonary artery HTN
  • cardiomyopathy
91
Q

Kawasaki Disease

A
  • unknown etiology: may be related to an infectious disease and underlying abnormalities in the immune system by an infectious insult
  • acute, generalized systemic vasculitis involving blood vessels throughout the body (pref. coronary arteries)
  • usually self-limited
  • without treatment 15-25% will develop coronary artery aneurysms.
92
Q

Kawasaki disease diagnosis

A

high fever ( > 102 F 39 C) persisting at least 5 days AND presence of at least 4:

  • changes in extremities: erythema of palms and soles, peeling
  • nonspecific polymorphous rash
  • bilateral nonexudative conjunctivitis
  • changes in lips and oral cavity (strawberry tongue)
  • cervical lymphadenopathy
  • echo: pick up coronary artery abnormalities
  • if 4+ criteria present, can be diagnosed on 4th day of illness
93
Q

Kawasaki disease treatment

A
  • aspirin: high dose in acute phase, low dose for 6-8 weeks if no coronary involvement
  • IVIG
  • steroids for those who fail to respond to initial therapy
    no coronary involvement:
  • echo
  • risk assessment q5years. known to habe higher BP and altered lipid metabolism.
    with coronary involvement:
  • small aneurysms: low dose ASA 1 year
  • large: ASA, possibly warfarin
  • 50% resolve post onset
94
Q

Acute Rheumatic Fever

A
  • delayed sequela of GABHS infection
  • big problem in developing countries
  • exaggerated immune response to bacteria in a susceptible host
  • family history of ARF, low SES, b/t 6-15yo
95
Q

Jones criteria for diagnosing ARF

A
evidence of preceding GABHS infection (+ throat cx/rapid test or + strep antibody titer) PLUS 2 major criteria or 1 major, 2 minor
MAJOR:
- carditis
- polyarthritis
- Sydenham's chorea (dance)
- erythema marginatum
- subcutaneous nodules
MINOR:
- fever
- arthralgia
- increased CRP, ESR
- prolonged PR interval
96
Q

treatment of ARF

A

Primary prevention
- treat acute GABHS tonsillitis/pharyngitis infections appropriately
- antibiotics (PCN, Erythromycin)
Goals of treatment
- symptom relief
- rest
- eradication of GABHS
Secondary prevention
- pts who have had ARF and develop subsequent GABHS infx are at high risk for recurrent ARF with progression to or worsening of RHD
- should continue until 21yo or 10y from a most recent acute attack, possibly lifelong depending on degree of cardiac involvement
