Endocrine Flashcards
How to diagnose T2DM?
- FPG >7.0 mmol/L or
- A1C>6.5% (adults)
*if either in 6 range it = pre diabetes
Others:
- 2hPG in a 75g OGTT >11.1mmol/L or
- Random PG >11.1 mmol/L
*if 2 tests are in diabetic range = diabetes confirmed
*if asymptomatic, repeat test on another day
*if only one test is in diabetic range, rpt only that test
*if symptoms present, diabetes can be confirmed with one test (typically fasting BG, but A1C is a better picture)
Who to screen for T2DM?
- Screen everyone >40 years old every 3 years
- if found to be pre-diabetic, screen more often than q3years
- If <40 years assess for risk factors annually
- If risk factors present screen every 6-12m
What are some risk factors for T2DM?
- Fam hx of T2DM (1st degree relative)
- Non-white, low socioeconomic status
- Hx GDM, pre-diabetes
- Hx delivery of microbic infant
- CV risk factors
- Presence of end organ damage typically associated with diabetes
What are the microvascular complications of diabetes?
- Retinopathy: microaneurysms, cotton wool spots, angiogenesis
- Nephropathy: Albumin Creatinine Ratio (ACR) > 2.0mg/mmol &/or eGFR <60mL/min
- Neuropathy: Monofilament or tuning fork test
What are the macrovascular complications of diabetes?
- Cardiovascular (MI, CVD): Lipids – Framingham risk score
- Cerebrovascular (CVA, TIA)
- Peripheral Vascular (PAD)
What is the monofilament test?
What score is considered positive?
Rapid screening for neuropathy using the 10g monofilament
3/8 = neuropathy likely
3.5/8 = not yet but likely to develop in next 4 yrs
5.5/8 = not yet and low risk of developing in next 4 yrs
When to Refer to specialty services for diabetics?
- Ophthalmology/Optometry: at diagnosis
- Podiatry: at diagnosis
- Neurology: atypical presentation/uncontrolled pain
- Nephrology: sustained ACR <60 &/or eGFR <30, chronic progressive loss of kidney function, difficult to control BP
- Cardiology: abnormal ECG, intermittent chest pain
What are you screening at EVERY Primary Care visit for a diabetic?
- BP (should be <130/80)
- Assess self-care, hypoglycaemia, smoking and nutrition
- Foot check (ask them if they are checking their feet)
What is the annual screening for diabetics?
- Random urine ACR and serum creatinine for eGFR
- Optometrist/Ophthalmologist
- Full foot exam (60 sec foot screen)
- Lipids (with ECG q2years)
- Flu shot/vaccination review
- Home glucometer calibration (they bring in their home glucometer and you check it with the office glucometer)
How often is the A1C checked?
Every 3-6 months
Side effects of hyperthyroidism
Everything is slowed down:
- cold
- dec weight
- amenorrhea
- exopthalmos
-
What are the Rotterdam diagnostic criteria for PCOS?
Must have at least 2 of 3 present:
- Hyperandrogenism (hirsutism, acne)
- Anovulation (no periods or unpredictable periods)
- Polycystic ovaries on U/S
What labs would you order is suspecting PCOS?
testosterone, prolactin, FSH, LH, FBG, lipids, beta-hcg
