MSK/Bone/Rheum Flashcards
Main Risk factors of OP in those >50years
Where you would consider doing FRAX/Qfracture —> ?BMD scan
FHx of OP, FHx of hip fracture, smoker, diabetes, IBD, HyperT, T1DM, COPD, CKD, Hx of anything that makes you fall
Alcohol, smoking
SSRI PPI
Main risk factors <50 for OP
Steroids >3months, perimenapausal, previous fragility fracture
What t score for osteroporsis
<-2.5
<-2.5 to -1 is osteopenia
T score is mean BMD for 30yr old women
What are the Qrisk guidelines for starting Tx
Oral bisphospahtes if >1%
Consider IV zolerdante (3monthly for 3 years) if >10%
Teriparatide SC injection is consider in what OP
Steroid related or men
What are some other examples of bone protections in OP
What supplements
HRT in perimenoapsual
Raloxifene
Denosumbab
Vit d (400-800) + calcium (not if <700)
Who should we consider screen for OP with dexa/Qfra
- age + 3 risk factors
All women >65 + men >75
Fragility fracture
High dose steroids >3months
Post menopausal with risk factors
Management of osteopenia
Consider zolerondic acid at 65yrs with hip changes
Re scan at 3 years
BMD is very specific but not very sensitive
Bone loss starts at 30years
Oral bisphosphates advice
Check teeth prior (ON jaw risk)
PPI doesn’t help dyspepsia - empty stomach, stand up, no meds within 30mins
Rare risk of subtrocnetntic fracture
R/v at 5 years
The most common cause of hypercalacaemia (>2.6)
- >3 looking for admission (mod)
Hx of malignancy
Hyperparathyroidism (usually mild - also low phosphate, and inappropriate Normal or high PTH)
Drugs - thiazides (also hyponataemia), lithium, vit d ++, vit A, combine ca + vit d preparations
What is most common cause of hyperparathroidism
Soldiatory adenoma!
Main reason of malignancy related hypercalcamia
Most common cancers
Tx
Secretion of PTH-related protein - paraneoplastic hypercalacamia
20% will be boney mets
Breast, lung, oesophageal, HNT, cervix
Oncology - bisphosphates can be consider
Management of hypercalaemic in those that don’t need admission
Rpt in 1 week with PTH + bone profile
Assess VitD
?malignayc - FBC, LFTs, serum and urine electrophoresis, urine hence hones
TFTs - thyroidxotcisit some times
What is the Biochem and causes of secondary hyperPTH
Low Ca, high PTH, high phosphate
- vit D def, chronic RF
What may occur after thyroid surgery
And what are the bloods like
Treatment
Primary hypoparathroidism
Low PTH, low ca, high phosphate
Vit D + Calcium supplements (need to take 4hours apart from Levothyroid), calcium citrate if on PPI
