SCP 2 RE Flashcards
In a diabetic foot exam, you notice that one of the patient’s feet is a reddish/purple colour, and the other is their normal skin colour. What could this indicate?
Unilateral discolouration is a sign of acute iscaemia
Name some factors that contribute to the development of foot ulcers:
Sustained hyperglycaemia Angiopathy (peripheral vascular disease) Abnormal immunity Neuropathy and loss of sensation Foot deformity Skin atrophy- dryness/cracks in the skin Friction/footwear/calluses Trauma- mechanical, chemical, or thermal
“A break in the skin which is failing to heal”
ulcer
What does the acronym “SINBAD” stand for?
Site Ischaemia Neuropathy Bacterial infection Area Depth
Most common site of foot ulcers?
the forefoot
___________ is necrosis secondary to inadequate perfusion (can be wet or dry)
Gangrene
Erythema of the foot could be due to infection or acute ________
ischaemia
It’s important to remove dead tissue in foot ulcers in order to prevent _______
sepsis
One sign of chronic lack of blood perfusion in the lower extremities is _____ loss.
hair
Sudden onset unilateral warmth, redness and oedema over the foot/ankle, usually with a history of minor trauma
Charcot arthropathy
NB: 30% can present without pain or discomfort
__________ sounds should heard in a Doppler ultrasound of the lower extremity . As the disease progresses, only _________ sounds are heard.
Triphasic, monophasic
The ________ _______ pulse is palpable on the dorsum of the foot in the first intermetatarsal space just lateral to the extensor tendon of the great toe
dorsalis pedis
Where would you palpate the posterior tibialis pulse?
Behind the medial malleolus
Impaired sense of vibration and proprioception indicate an impairment in which area of the CNS?
the dorsal columns
What are the sites on the foot at highest risk of peripheral neuropathy?
Toes and heads of the metatarsals
What type of tool is used to test for peripheral neuropathy in the feet?
10g monofilament
Where should you place a tuning fork to test a patient’s sense of vibration?
Start by placing the tuning fork on the patient’s sternum to test whether they can feel it, then move it to the interphalangeal joint of the 1st hallux. Move to proximal bony prominences if they cannot feel vibration distally.
Which nerve root is associated with the “ankle jerk” reflex?
S1
What is one of the first nerve roots affected in diabetic neuropathy (due to its long length?)
S1
If someone has a “moderate” diabetic foot risk score, how often should they be screened, and by whom?
Annual screening by a podiatrist
If someone has a “high” diabetic foot risk score, how often should they be screened, and by whom?
Annual screening by a specialist podiatrist
What are the four components of a diabetic foot exam?
Inspection
Palpation
Sensation
Gait assessment
Difficulty rising from a chair could potentially be a sign of what endocrine condition?
hypothyroidism (proximal muscle weakness)
What is a major (lifestyle) risk factor for eye disease in Grave’s patients?
smoking
A rare complication of autoimmune thyroid disease that presents with digital clubbing and swelling of digits and toes is known as
thyroid acropachy
Oncholysis can be a sign of what endocrine condition?
Hyperthyroidism
How might a patient’s pulse be affected in underactive and overactive thyroid conditions?
Hypothyroid- bradycardia
Hyperthyroid- tachycardia and/or AF
Medical term for protrusion specific to the eyes
Exopthalmos
Name eye signs that could be seen in hyperthyroid (Graves disease) patients
Exopthalmos/proptosis Chemosis (conjunctival injection) Corneal inflammation Lid retraction Lid lag (with downward eye movement) Pain with eye movements Double vision
Inflammation of orbital tissue, retrobulbar pain, diplopia, lid-lag, chemosis, and proptosis/exopthalmos are signs of?
Thyroid eye disease.
NB: The higher the TSH receptor antibody levels, the more likely it is that the eyes are going to be affected
What are NOSPECS classification or EUGOGO activity scores used to determine?
How quickly a patient with signs of thyroid eye disease should be referred to an opthalmologist
What abnormality presents as a painless, firm, midline neck mass that elevates with swallowing and tongue protrusion?
A thyroglossal duct cyst
