What percentage of patients with mild asthma will outgrow asthma by adulthood? What about severe asthma?
60% and 30%
True or False.
Asthma is more common in girls than boys.
False. Boys > Girls until puberty when it equalizes.
An asthmatic has symptoms less than twice weekly and night symptoms less than twice monthly. What class of asthma is this? How do you treat?
Mild intermittent. Give bronchodilators alone.
An asthmatic has symptoms more than twice weekly and night symptoms more than twice monthly, but has normal baseline PFTs. What class of asthma is this? How do you treat?
Mild persistent. Give bronchodilators + low dose inhaled steroids. Leukotriene inhibitors are second line.
An asthmatic has symptoms more than twice weekly, but not daily and night symptoms more than twice monthly, but not daily. Baseline PFTs are abnormal. What class of asthma is this? How do you treat?
Moderate persistant. Give low dose steroids and long acting bronchodilator.
True or False.
Atelectasis on x-ray of an asthmatic with acute exacerbation is a sign of pneumonia.
How do you define mild asthma exacerbation? How do you treat?
Peak flow >50% expected. Treat with bronchodilators and po steroids. Discharge from ED. Do not give antibiotics.
When do you give levalbuterol as opposed to albuterol for severe asthma exacerbation?
With severe tachycardia, tremor and irritability.
True or False.
Chest PT and inhaled mucolytics should be included in treatment of severe asthma exacerbation.
False. There is no role for these in routine care of severe asthma exacerbation.
A patient with asthma exacerbation has pCO2 that is normal but the patient can not speak full sentences, and is more sleepy. What does this indicate?
Pt is getting fatigued and this is an ominous sign of CO2 retention. Consider increasing ventilation support with non-rebreather or intubation depending on clinical picture.
A 7yo child is brought in because for the past several nights, she has been having a nighttime cough with whitish mucous production. She has no fever, has been previously healthy and has no known new pets or detergents or allergies. What is her likely diagnosis?
Reactive airway disease
Preschool aged asthmatics may have an acute exacerbation without audible wheezing. How do you make a diagnosis of asthma exacerbation?
They might not move enough air to elicit a wheeze. Rely on history, other parts of exam like retractions and nasal flaring and check cxr.
CXR will show hyperinflation and increased peribronchial markings.
What are 6 non-asthma causes of wheezing?
Drinks (aspiration)
Slings (vascular)
Rings (vascular)
and other Things (Foreign body)
What percentage of asthmatics have positive immediate type allergy skin tests?
What is the best climate to run outdoors for someone with EIA?
hot and humid.
What are four causes of exercise intolerance other than EIA?
Cardiac disease
Muscle weakness
Psychological factors and Poor Shape
A 2yo child is brought in for a respiratory infection that is not clearing. She has a localized wheeze and reduced breath sounds over one lung. Her cxr shows mediastinal shift. What is her likely diagnosis?
Foreign body aspiration.
What are 4 risk factors for persistent asthma?
Onset before age 3
Increased IgE
Maternal history of asthma
What percent of infants with severe RSV will develop recurring wheezing?
What is the benefit of steroids in prevention of asthma?
they decrease bronchial inflammation and bronchial hyperresponsiveness.
Unlabored breathing + intermittent non-productive cough + right sided expiratory wheeze = ?. How do you confirm diagnosis and treat?
Foreign body aspiration. Check CXR. Confirm with bronchoscopy which can remove the object as well.
What is pulsus paradoxus?
It is where the difference in blood pressure during inspiration and expiration should not be greater than 10; more than 20 suggests pulmonary or cardiac problems.
What is the first step in assessing respiratory distress?
A) Check ABG
B) Check Respiratory Rate and effort
C) Auscultate
D) check for tachycardia and diaphoresis
B) Look for tachypnea, retractions and inability to speak in early phases, but later, when patient is fatigued, ie in failure, you should look for sweating, anxiety and tachycardia.
True or False.
Pulmonary hypertension compromises the ability to reduce carbon dioxide and results in hypercarbia.
False. It reduces oxygenation and causes hypoxemia
What happens at the kidney level in pulmonary hypertension?
The kidneys "see" hypoxemia, so release erythropoetin and thus increase the HCT. This results in increased headaches, joint pain, clots and PE and thrombocytopenia.
Which of the following result in impaired effectiveness of coughing?
A) Vocal cord dysplasia
B) CNS disease
C) Thoracic deformity
E) Muscle Weakness
F) All of the above.

Sweat chloride testing
TB skin testing
A 6yo presents with chronic cough sweat testing, TB testing and CXR are all normal. What is your next step?
A 7yo has a loud barking cough. His mother says it is only in the day. She has had to take him home from school for this on multiple occasions but he doesn't have it at home and he sleeps fine. What is the most likely diagnosis?
Psychogenic cough.
An 8yo has fever, night sweats, weight loss and a dry hacky cough. What should be your screening test other than CXR?
TB skin testing.
Chronic cough
Low albumin
low sodium
Pseudomonas infections
What is your diagnostic test of choice. What is your diagnosis?
Sweat test. It should be <60 if normal. Otherwise this is CF.
If a sibling of someone with CF marries someone from the general population what are the odds of them having a kid with CF?
The caucasian carrier rate is 1/25.
1. both parents must have been Rr
2. the sibling does not have disease, so the rr possibility is out
3. the sibling is either RR or Rr and has 1/3 chance of RR and 2/3 chance of Rr.
4. So the sibling (carrier) x avg joe (carrier) = kid risk equation is:
2/3 x 1/25 x 1/4 = 2/300 = 1/150
What is the gold standard in testing for CF?
Sweat chloride test?

What is are the major vitamin deficiencies in CF? How do they manifest?
Vitamins ADEK
Vitamin A deficiency: eye problems and neuro problems
Vitamin D: bone and muscle problem
Vitamin E: skin and neuro problem
Vitamin K: prolonged PT
What is the treatment for acute CF exacerbation?
aminoglycosides and penicillin/piperacillin
Which bug is responsible for most CF infections early in life?
S. aureus. Pseudomonas is in older kids.
What is cor pulmonale?
Right heart failure or RVH due to pulmonary hypertension or severe upper airway obstruction.
Lower body edema
S3 gallop
child does not have congenital heart disease.
What is your diagnosis? Is this reversible?
This is cor pulmonale. It is irreversible if it is from pulmonary hypertension but reversible if it is surgically corrected upper airway obstruction.

Name 2 causes of complete obstructive apnea. How do you treat them?
1. Severe subglottic stenosis
2. Vocal cord paralysis.
Require tracheostomy.
What is central apnea?
It is apnea where there is no CNS signal. Give caffeine and put on vent.

A) Pulmonary hemorrhage
B) Pulmonary edema
C) Tension pneumothorax
