Screening and Genetics +/- Screening Flashcards
Who qualifies for a self collected CST?
Any women who’s been sexually active between age 25-74.
Which women are not eligible for a self collected CST?
anyone who requires a co-test.
this includes:
Symptomatic patients, in particular those presenting with unexplained persistent abnormal vaginal bleeding (post-coital, unexplained inter-menstrual or post-menopausal bleeding)
Surveillance of patients exposed to DES in utero
Surveillance of adenocarcinoma in situ
Patients undergoing a test of cure (treated, biopsy confirmed HSIL)
For Colorectal cancer (CRC) screening, who is classified as Moderately increased risk?
(3)
Asymptomatic persons with a single first degree relative diagnosed under 55yo
Or
Asymptomatic persons with 1 first degree AND 2 or more second degree relatives diagnosed at any age (with CRC)
Or
2 or more second degree relatives diagnosed at any age
For those at moderately increased risk of CRC (1-4% in 10 years), what is the screening recommendation?
- iFOBT 2 yearly from 40-49
- 5 yearly colonoscopies from 50-74
- ?aspirin 100mg, orally, daily for at least 2.5 years between ages 50-70
What is the evidence behind the triple test for breast cancer?
The triple test is more accurate at detecting
breast cancer than any of the individual
components alone.
When performed appropriately the triple test
will detect over 99.6% of breast cancers.
A triple test negative on all components
provides good evidence that cancer is unlikely
(less than 1%).
When to refer for breast lump or discharge?
any one component of the triple test is positive i.e:
a cyst aspiration is incomplete, results in bloody aspirate
(not traumatic) or a lump remains post-aspiration
spontaneous unilateral, bloody or serous discharge from a
single duct especially in women 60 years and over
eczematoid changes of the nipple-areolar skin which persist >1-2 weeks or do not respond to topical treatment
inflammatory breast conditions that are not resolving after 2 weeks of antibiotic treatment
if any test result is inconsistent with other results and requires additional investigation.
When should you start performing an absolute cardiovascular risk on patients without known cardiovascular disease?
Everyone from age 45,
done every 2 years
From age 35 in all ABTI persons, also every 2 years.
Can extend screening to every 5 years for low risk adults.
Can continue screening past the age of 74, but enter in 74 to the calculator. though might just underestimate risk
What to do if there is a high cardiovascular risk on the Framingham risk calculation? ( >15% )
- Lifestyle advice
- Start blood pressure medication. preferrably an ACEi
- Start lipid lowering medication preferably a statin.
What people are automatically high cardiovascular risk? In terms of primary prevention?
- > 60 years old WITH diabetes
- Diabetes with microalbuminuria
- Moderate to severe CKD
- Diagnosis of FH
- ABTI > 74
- Choleseterol > 7.5 (without medication)
- BP. Systolic> 180, diastolic> 110
A women aged 55, comes in for a cardiovascular check up. No known cardiovascular disease.
She had bloods prior, showing a FBL of 11, which was repeated and came back also at 11mmol/L. Also a fasting total cholesterol was noted at 6.8.
Her blood pressure today is systolic of 178.
Hx
Non smoker
What is her cardiovascular risk?
high risk according to this chart.
though when I enter into the CVD risk calculator she only comes up as medium risk when entering in the HDL at 2.0
with HDL of just 1.0 she was similar risk to the chart. So it turns out the HDL level is quite important.
When do you start screening for diabetes?
In everyone do an AUSDRISK from age 40.
in ABTI do an AUSDRISK from age 18
Repeat this every 3 years.
AUSDRISK tool doesn’t require any blood test. Just a series of questions with a waist circumference.
if risk is high (score > 12) then proceed to test for diabetes.
This whole thing doesn’t make a great deal of sense for the general population as the CVD risk is calculated every 2 years which will start at age 45 and requires a test to detect diabetes anyway .
When should you ask about stroke symptoms or rather assess stroke risk?
Should ask about stroke symptoms in anyone with AF or high cardiovascular risk
What is the ABCD2 rule?
To detect stroke risk in those presumed to have a TIA
Everyone should proceed to a CT brain, but the tool will determine the urgency.
Remember to screen for AF and use the CHA2DS2VA to decide about anticoagulation.
- When do you start screening/testing for CKD?
2.What is a kidney health check
1.
A. ANYONE with the following risk factors should get tested every 2 years (from age 18 onwards).
> 60 (easy to add onto CVD check)
Smoker
Diabetes
Hypertension
Family history of kidney disease
Obesity BMI>30
History of AKI
Establish CVD
*NB: Ask/investigate persons aged 18 and over if they have any of these risk factors and proceed to test (kidney health check) every 2 years if they do
*NB2: For ALL ABTI irrespective of other risk factors, start testing for CKD (using a kidney health check) from age 30 onwards.
- Kidney health check involves
a. EUC with eFGR
AND
b. Urine ACR
AND
c. Blood pressure check
How often should you measure BP in those without known disease.
why would you do this (2)?
Every 2 years in everyone aged over 18.
This is to evaluate
1. overall CVD risk (45 yo+ or 35 years for ABTI)
2. to potentially find those with secondary causes of hypertension
What are some tangible complications (“harms”) associated with over-diagnosis of prostate cancer and associated work up.
(3)
- Urinary incontinence from those treated with a radical prostatectomy
- other urinary problems in those treated with radiation
- Erectile dysfunction in those treated with surgical, radiotherapy or medical means
- Bowel problems which occur in 20% of those treated with external beam radiation.
What are the risk categories for prostate cancer?
(3)
No increased risk = no family history
slightly Increased risk (2-3 x normal) = one brother or father with prostate cancer aged < 60
Increased risk (9-10x normal) = 2 brothers and a father, essentially 3 family members with prostate cancer
For patients with NO increased risk (no family history of..) of prostate cancer what is the recommended screening, and when should you investigate further?
When to act on a PSA?
if under 50 years old, there is no recommendation
over 50 years?
then discuss the benefits and risks and let patient decide, follow up with 2 yearly PSAs.
If PSA is over 3.0ng/L or in the 95th percentile for age then offer further investigation
In those with an increased risk of prostate cancer what is the offered screening after discussing the harms and benefits?
(2)
Two risk categories
If slight increased risk (2-3x) normal then offer PSA at 45, and if normal only again after 50
If increased risk (9-10x) then offer PSA from aged 40, and if it is normal then doesn’t need repeat testing until aged 50
Then from aged 50 offer 2 yearly screening as with the general population
What is a normal PSA reading?
What is elevated
what is abnormal
either below 3ng/L or below the 75% for age
elevated would be <3 but in the 75-95%ile range for age
abnormal is either over 3ng/L or >95%ile for age
What are further investigations to order if PSA is raised?
if over 5.5 - refer for likely biopsy and or multiparametric MRI (MRI should only be specialist initiated however)
if over 3.0 but under 5.5, repeat PSA in 1 month WITH a Free to total PSA
- if the repeat is > 5.5 the refer on
- if the repeat is still between 3-5.5 but free to total is <25% the refer on
if- between 3.0 - 5.5 and free:total is >25% may not need biopsy
What is the indication for a multiparametric MRI of the prostate?
it’s only for those have already undergone a U/S guided biopsy that is negative, but you want to know if a second biopsy is needed.
Furthermore this is NOT for primary care practitioners to order.
And needs to be done in a specialist centre.
Symptoms of Male Androgen Deficiency?
(6)
Reduced libido
Lethargy
Reduced spontaneous erections
Hot flushes
Reduced Facial hair growth
Breast discomfort
Can also have
Worsening concentration
lack of motivation
Reduced muscular bulk
Increased body fat
Signs of androgen deficiency?
Gynaecomastia
Loss of axillary hair
Smaller testes
Lower bone mass
What can cause “functionally” low testosterone?
(4)
Opioid use
Diabetes
Depression
Obesity
What testing do you do for androgen deficiency?
What do the results mean?
first: total testosterone
if low then repeat
-total testosterone
WITH
-FSH/LH
If low testosterone and high FSH/LH, there is an organic problem with the testes–> refer
If there is low testosterone and low or normal FSH/LH then there is a HPA (hypothalmic pituitary axis) problem –> refer
What are testicular causes for male androgen deficiency?
(5)
orchitis,
cryptorchidism (one testes absent)
Androgen synthesis inhibitors
cytotoxic or radiation damage
Klienfeilter syndrome if testes are small
Pituitary causes for male androgen deficiency?
(6)
pituitary tumours
hyperprolactinaemia
pituitary surgery or radiation
iron deposition
hypophysitis (pituitary gland or infundibulum inflammation)
congenital syndromes (kallman)
