Q

Management of osteopenia

A

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

Q

Oral bisphosphates advice

A

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

Q

Main reason of malignancy related hypercalcamia
Most common cancers

Tx

A

Secretion of PTH-related protein - paraneoplastic hypercalacamia
20% will be boney mets

Breast, lung, oesophageal, HNT, cervix

Oncology - bisphosphates can be consider

Q

Management of hypercalaemic in those that don’t need admission

A

Rpt in 1 week with PTH + bone profile
Assess VitD
?malignayc - FBC, LFTs, serum and urine electrophoresis, urine hence hones
TFTs - thyroidxotcisit some times
