The Review Course Flashcards
(384 cards)
Cough:
list acute, subacute and chronic cough ddx
Acute <3wks:
- Something fatal? pneumonia, HF, neoplasia, foreign body, PTX
- Medication: ACe inhibitors
Subacute 3-8 wks:
- Post-viral
- Infectious : bacterial, viral
- Early chronic: asthma, reflux, upper airway cough syndrome (post nasal drip), covid 19
Chronic >8 weeks:
- COPD
- Infectious (ascaris?)
- Refractory or unexplained cough
- Less common: cystic fibrosis, bronchiectasis, eosinophilic bronchitis
Always ask travel, occupation, contacts, critters
Cancer:
- Prostate
- Testicular
- Lung
- Ovarian
- Cervical
- Melanoma
- Colon
- Breast
- Pancreatic
-
- Prostate cancer : no screening for average risk
- Testicular cancer : screen if cryptorchidism, FMHx, PMHx (screen with BHCG, alpha-fetoprotein). Tx Lop it off surgery.
- Lung cancer: Low dose CT 55-74yo if 30pk/yr smoker (smoking now or in last 15 years). Annually x 3 max. No CXR. Think Radon gas 2nd leading cause of lung cancer, recommend home radon test kit.
- Ovarian: do not screen if asx low risk. High risk (BRCA positive) then screen.
- Cervical: screen 25-69 q3years (DO not screen: never sexually active, weakened immune system, HIV is every year no q3yrs, sx cervical cancer, previous abnormal screening, does not have a cervix)
- Melanoma: refer if high risk (older, male, previous skin cancer, FMHx, # nevi (low risk <15), light skin, red hair, multiple sunburns, actinic skin damage)
- Colon cancer: FIT test 50-74yrs q2yrs, not affected by NSAIDs, OACs or ASA (or flex sig q10yrs)
- Breast cancer: 50-74yrs q2-3years if average risk (otherwise shared decision making)
- Pancreatic cancer: only if high risk (BRCA1 +, FMHx, Peutz-Jeghers syndrome).
Febrile neutropenia
DOs/DONTs
DOs: look in mouth for mucositis, look for source (consider fungal)
Early abx: cipro + amox if low risk, tazo if high risk. consider antifungals.
DONTs: rectal exam/temperature
Unexplained weight loss
Investigations
Weight, height
Serum Hemoglobin
Serum sodium, potassium, eGFR
Serum urea, creatinine
Serum PSA
Fecal Occult Blood
Chest x-ray
Chest, abdomen, pelvis CT (with contrast!!!! for cancer)
CAREFUL IF THEY ASK FOR SERUM
Shortness of breath
- r/o PE with
- Wells first, if low risk then PERC
- pregnant: YEARS rule –> signs DVT, hemoptysis, PE most likely (1pt each) –> d-dimers : r/o PE if <500 (1-2-3pts), <1000 (0pt)
SOB:
investigations
ECG
Echocardiogram
Troponin
Arterial blood gas (if acute)
Chest x-ray
Pulmonary function
CT chest if no clear diagnosis
Shortness of breath
Zebra causes lung and heart
Extra pulm/cardiac causes:
Life threatening
Lung: recurrent fungal pneumonia, fibrosis, post-COVID 19 sequelae, pleural effusion
Heart: occasional arrhythmia, cardiomyopathy, malignancy, mycobacterial, aortic stenosis
Other: anxiety, abnormal thyroid, altitude, anemia, acid reflux, allergy, deconditioning
Life threatening: foreign body, anaphylaxis, pneumothorax
Pneumothorax primary spontaneous <2cm on xray: dos and donts
Do: observe 4 hours, d/c if well tolerated and stable on xray, offer needle drainage instead of chest tube (less pain, higher failure rate) but 85% DO NOT require drainage
Don’t: CT/POCUS (not necessary)
COPD
Ddx:
Does oxygen therapy change time to death/hospitalisation?
Non-pharmaco tx to think about
When can you consider opioids?
Ddx: think pre-COPD (resp sx but normal lungs)
No
Acupuncture, active mind-body therapy, yoga, tai chi
In palliative context
COPD:
3 elements to consider with treatment
- Daily macrolides (reduce exacerbations)
- Action plan (reduce hospital use)
- CPAP if COPD + OSA (reduce mortality + admission)
COPD:
Explain treatment for COPD mild vs mod/severe
Mild: LAMA or LABA (no longer SABD x 2023)
Moderate to severe:
- if lo AECOPD: LAMA + LABA + ACS
- if Hi risk AECOPD: triple + oral (roflumilast/pde-4 inhibitor, n-acetylcysteine, daily azithromycine)
ALWAYS SABD PRN
Mild = COPD Assesment test (CAT) <10, FEV1>=80%
Mod/severe = CAT>=10, FEV1<80%, mMRC scale >=2
What other one test would you order for COPD?
Blood eosinophils –> if >=300 change to ICS + LABA instead of LAMA/LABA
Can you diagnose COPD in non-smoker?
It could be second-hand but think about other causes:
- Alpha-1 anti-trypsin (if dx <65yo or <20pk/yr)
- Bronchiectasis
- Infectious
- Cardiac
- Mass
COPD:
acute exacerbation vs chronic worsening
Treatment for both
Treatment for AE
AE: days
Chronic worsening: over months
For both : stop smoking, optimize inhalers + review technic
Treatment for AE:
- Steroids
- Antibiotics if CRP >40 or 2/3 winnipeg symptoms (sputum purulence, sputum volume, dyspnea)
—> treat as per local resistance pattern
COPD:
common pathogens
Ear bugs: H.influenzae, S. pneumonia, M. catarrhalis
Complicated: ear bugs + Klebsiella, pseudomonas, gram negatives
COPD: prevention, refer, start
Prevention:
- Vaccination: influenze, pneumococcal vaccines, covid-19
- Exercise to prevent exacerbations
- smoking cessation
Refer early: respiratory therapy, pulmonary rehabilitation, respirology, smoking consellor, palliative
Start: short-acting beta-agonists if mild + intermittent sx, long-acting muscarinic antagonist if regular mild sx.
How do you mange COPD/Asthma overlap syndrome
ICS/LABA (fluticasone propionate + salmeterol) +/- LAMA (tiotropium)
Refer +/- biologic medications
Asthma:
diagnosis in pediatric population
<6 years old: reverse with salbutamol, wheezes, r/o other causes (croup, foreign body, asthma can overlap with bronchiolotis or virus induced wheeze)
> = 6 years old : PFT
Main cause of bronchiolitis:
- diagnosis
- cause
- management
- prevention
RSV bronchiolitis
- Investigation = NONE if uncomplicated. Nenonates may present with apnea or cyanosis only.
- Cause = RSV 80%, mycoplasma, pertussis
- Management = supportive (admit if needed to maintain saO2 >90%
- Prevention = vaccine
How can you assess asthma severity at ER?
PRAM score:
- <4 mild
- 2-7 mod
- >7 severe
Asses: O2 sat, retractions/indrawing, air entry, wheeze
Asthma:
what environment exposition increases risk in children?
Frequent use of cleaning products
Antibiotics without being breastfed in 1st year of life
Asthma:
3 elements of hx with adult
- triggers
- past severity
- current control
Asthma control if:
PER WEEK:
=<2 days with symptoms
<1 day night symptoms
=<2 doses of reliever
NO interference with work/school/exercise
Mild infrequent exacerbations
ASTHMA diagnostic PFT values:
