hip osteoarthritis - pain exacerbated by
internal rotation | deep pain
61
meralgia paresthitica
caused by compression of the lateral femoral cutaneous nerve at the waist --> burning pain and paresthesias at the lateral thight --> unaffectd by motion
62
impingement of the lumbar nerve roots - hip mobility?
normal
63
How to confirm diagnosis of ankylosing spondylitis
x-ray of sacroiliax joints (or MRI) | - HLA-B27 is VERY sensitive but not specific (only 5% of HLA-B27 (+) have AS --> not necessary for diagnosis
64
RA - treatment
all patients should be started on disease modifying antirheumatic agents as soon as possible as joint damage begins early --> NSAID are adjunctive therapies for symptomatic releif but do not reduce disease progression - Glucocorticid can alo releve symptoms and short term radiographic progression but not preventive eventual joint destruction - Methotrexate is the best initial choice
65
RA - do not respond after 6 months
additional DMARD such as TNF as step up
66
dermatomyositis - management
high dose glucocorticoids PLUS glucocorticoid sparing agent | - screening for malignnacy

lumbar disc herniation - presentation
acute back pain with unilateral radiation down the sciatic nerve to the foot (sciatica) --> usually follows an inciting event and LuMbar flexion makes the pain worse
76
lumbar stenosis - presentation
back pain in patietns older than 60 --> back pain radiating to the thighs that is worse with lumbar extension and persists while standing still
77
age related sicca syndrome
exocrine output from lacrimal and salivary glands declines with age, associated with atrophy, fibrosis and ductal dilation of the glunds --> decreased blink rates, oxidative damage, excessive evaporation of teras and use of anticholinergic medication in older individuals can also contribute (think about it if shogren syndrome like but older than 65 and ANA (-))
