Management of exercise-induced (asthma/bronchospasm)
|
if severe, use prophylactic inhaled beta-2 agonist (eg albuterol) 5-10min before exercise
|
|
|
results of methacholine challenge testing in exercise-induced asthma
|
equivocal -- exercise-induced asthma not necessarily correlated with allergic asthma
|
|
|

|
crackles, clubbing, chest radiograph changes

|
|
|
defn and mgmt of mild intermittent vs mild persistent asthma
|
mild intermittent: <= 2 days of sx/wk, <= 2 nocturnal events / month; both treated with albuterol prn, mild persistent also tx with corticosteroid
|
|
|
use of ipratropium bromide in asthma control
|
only for acute exacerbation in emergency situation; not useful for longterm management

|
|
what to do in moderate persistent asthma if steroids are not sufficient?
|
add long-acting beta agonist
|
None
|
|
does myesthenia gravis better or worsen as the day progresses?
|
worsens (unlike lambert eaton)
|
|
|
vocal cord dysfunction vs asthma
|
difficult to distinguish; vocal cord dysfunction: not responsive to asthma tx, nl spirometry, no nocturnal sx, difficulty with INSPIRATION > EXPIRATION; Tx of vocal cord dysfunction: speech therapy
|
|
|
DOE with nocturnal cough suggestive of what etiology
|
heart failure
|
|
|
why don’t you always hear rales with chronic heart failure?
|
dilation of pulmonary lymphatics ==> no pulmonary edema at baseline
|
|
|
what test to rule out heart failure?
|
BNP: if < 100, HF unlikely
|
|
|
carotid upstrokes in MR vs PDA
|
brisk in PDA (increased stroke volume); not brisk in MR b/c decreased forward flow
|
|
|
changes to pulse pressure with PDA
|
widened b/c of diastolic runoff into pulmonary artery
|
|
|
risk factors for stroke in pt with afib
|
hx of stroke, hx of MI, hx of HTN, age > 65, DM, LAE, LV dysfunction
|
|
|
tx of afib
|
warfarin + betablocker/amiodarone
|
|
|
pathophys and tx of peripartum cardiomyopathy
|
in 3rd trimester, increased volume load --> failure (pulm edema, SOB, tachy); tx with delivery (vaginal if possible), no ARB/ACEi (teratogenic)
|
|
|
risk factors for peripartum cardiomyopathy
|
black women, multi gestations/parity, >30yo, hx
|
|
|
characteristics of mitral stenosis
|
1) opening snap; 2) diastolic rumble; 3) pre-systolic accentuation (atrial kick)
|
|
|
easy way to tell if pulmonary hypertension is 2/2 ASD or VSD
|
cyanosis
|
|
|
how to prevent influenza in a high risk pt?
|
vaccination + amantadine/rimantadine x 2wk (only bc high risk) for Influenza A, oseltamivir for Influ A and B
|
|
|
prophy for influenza B
|
oseltamivir
|
|
|
only tx proven to prolong life in hypoxemic COPD pts
|
O2 (also smoking cessation, lung-volume-reduction surgery)
|
|
|
nasal O2 prescribed at what PaO2?
|
<55, or if cor pulmonale, < 60
|
None
|
|
what causes morning headaches in COPD?
|
CO2 retention
|
|
|
indications for pulmonary rehabilitation
|
pts with chronic resp impairment who are dyspneic despite optimal medical management
|
|
|
tx of acute COPD exacerbation
|
bronchodilators (eg albuterol -- not most effective, but v few s/e)
|
|
|
effectiveness of influenza vax in preventing hospitalization of elderly for PNA / influenza
|
good! 30-70%
|
|
|
how often does elderly person at risk need to get vax for influenza/pneumococcus?
|
influenza: yearly; pneumococcus: once
|
|
|
what kind of surgeries pose greatest risk to COPD pts?
|
upper abdominal / thoracic surgeries
|
|
|
reasons to use ACEi or ARB in hypertension
|
1) DM; 2) renal failure (elev Cre) -- also beta-blockers; 3)
|
|
|
target BP in diabetics with HTN
|
135/80
|
|
|
what is characteristic of BP in hyperthyroidism?
|
elevated SYSTOLIC ONLY (nl diastolic)
|
|
|
lifestyle changes that decrease blood pressure
|
AEROBIC EXERCISE, also weight loss (1kg --> 1mmHg), reduced salt intake, decreased alcohol / smoking
|
|
|
hypertension at young age with hypokalemia
|
look for hyperaldosteronism by measuring serum renin:aldo ratio; alt: herbal supplements, black licorice, beta agonist inhaler
|
|
|
obstructive sleep apnea a/w what chronic condition?
|
hypertension (independent of obesity)
|
|
|
tx of gestational hypertension
|
methyldopa -- doesn't decrease risk of preeclampsia, but also does not affect neonatal outcomes
|
|
|
Cr changes after initiation of ACEi
|
slight elevation common after BP normalized (kidneys adjusting to lowered renal perfusion pressure); still, need to be vigilant due to potential occult bilateral RAS (usu see >20% inc in Cre)
|
