Rheumatology. I'm not sure there is a more gray area of medicine... perhaps that's why I don't like it that much. I remember sitting in rheumatology class listening to cases thinking, "it could be any of the rheum diseases that we've talked about!" They all sound the same and there is no ONE test that gives you the answer. I find it immensely frustrating (perhaps why I ended up in a surgical field), but I tip my hats to the providers that work in it. It is so difficult to pin down a diagnosis and successfully treat a patient with rheum issues... so for me, I stick to the basics.
See below for my knowledge extent on these rheum/orthopedic PANCE/PANRE test-able gems:
Osteoarthritis (OA)
Exercise, PT
If knee joints involves - encourage weight loss indicting
Pool activities
NSAIDS
Rheumatoid arthritis (RA)
Aspirin, other NSAIDS
methotrexate for severe cases
benefits take months to see after therapy initiation
Ankylosing Spondylitis
PT
Indomethacin
Bamboo spine on plain films
SLE
NSAIDs for joint symptoms
Benign cases only need supportive care
Systemic corticosteroids for serious complications
Could be a cause of thrombosis in young women (oral contraceptives can also cause this)
Rickets
Vit D deficiency
Osteomyelitis
Aspirate and culture
Immobilize
Generally start with IV antibiotics then follow with PO antibiotics
