Medical Manifestations: Endo/Heme/Onc Flashcards
(146 cards)
Endocrine diseases w/ rheum manifestations
-DM
-Hyper/Hypo TSH, PTH
-Acromegaly
-Cushings
-Hyperlipoproteinemia
** MSK / Rheum complications in DM **
- Charcot joint, diabetic osteolysis
- Diabetic stiff hands (cheiroarthropathy) - prayer sign
- Amyotrophy, Muscle infarction
- Adhesive capsulitis
- Calcific shoulder periarthritis
- CRPS (shoulder hand syndrome)
- Flexor tenosynovitis (trigger fingers)
- Dupuytren’s contractures
- CTS + Thenar atrophy
- DISH
- Septic joint / OM
** Diabetic cheiroarthropathy pathogenesis**
- Excessive glycosylation of dermal and periarticular collagen
- Decreased collagen degradation
- Increased dermal hydration
** Diabetic cheiroarthropathy risk factors**
-DM duration,
-Glucose control
-Renal/retinal microvascular disease
** Charcot MSK manifestations**
-Midtarsal collapse → Rocker bottom feet
-Painless, swelling, deformity (tarsometatarsal, ankle, knee, hip, spine)
-Bony prominence skin ulcer, infxn
** Charcot radiographs **
5D’s:
- Destruction,
- Debris,
- Density (increased),
- Disorganization,
- Dislocation
** Charcot pathogenesis **
- Sensoral neuropathy + repetitive microtrauma
- Autonomic neuropathy → MORE blood flow
Both of which cause more inflammation, osteoclastic resorption, osteopenia, and #
** Charcot Tx **
- Protected weight bearing,
- Soft casts, good shoes,
- Treat/Prevent skin ulcers
- Neuropathic meds
- Amputation as needed
Diabetic osteolysis
– what is it
– pathogen
Osteoporosis / Resorption of distal metatarsal bones and proximal phalanges +/- acroosteolysis
-Pathogenesis: unknown, ~to charcot
Diabetic amyotrophy manifestations
+what doesnt it have
-Muscle wasting, weakness AND SEVERE pain (proximal muscles: pelvis, thigh, paraspinal, shoulder girdle)
-Distal symmetric neuropathy, autonomic neuropathy
-NO diabetic retinopathy or nephropathy
Diabetic amyotrophy pathogenesis
Injury to peripheral nerves, nerve roots, lumbosacral plexus via:
-Ischemia
-Immune mediated microvasculitis
-Inflammation
Diabetic amyotrophy
– nerve bx findings
– muscle bx
Nerve: Inflammatory infiltrate of blood vessel
-Muscle: fiber atrophy w/o inflammation
Diabetic muscle infarction
– Manifestations
– Ix
Acute onset pain/swelling thigh or calves
-Elevated CPK
-MRI to r/o infxn, malignancy
-Excisional Biopsy
Dequervain’s tenosynovitis pathogenesis
-Microvascular disease affecting nerves & blood vessels
- Protein glycosylation
- ECM protein deposition in skin/ & periarticular structures
Dupuytren’s contracture pathogenesis
Microvascular ischemia → contractile myofibroblasts producing increased collagen
CTS physical exam tests
Tinel’s
-Phalen’s
-Durkan’s
CTS manifestations
Nocturnal paresthesias
-Hand pain
-Pain radiating to elbow/shoulder (Valleix phenomenon)
-Thenar atrophy
CTS pathogenesis
Neuropathy due to:
-Extrinsic compression
-Microvascular disease ischemia of vasa nervorum
SSc DM complication mimickers
Diabetic stiff hand (flexion contracture and indurated digits)
-Distal neuropathy ~ Raynaud’s
-Scleredema diabeticorum (thickened skin upper back/neck)
DM meds causing rheumatic manifestations
OP:
- Glitazone
- SGLT2 (-flozin)
Arthralgia/myalgia:
- DPP4i (-gliptins)
Hypothyroidism MSK manifestations
-Myxedematous arthropathy (noninflammatory; ++viscous 2/2 hyalronic acid)
-Reversible bone marrow edema (~AVN)
-CPPD
TRAP
-Tunnel (CTS)
-Raynauds
-Aching myalgia
-Proximal muscle weakness/stiffness with high CK
HYPERthyroid rheum syndromes
-OP
-Myopathy (painless prox muscle weakness)
-Thyroid acropachy
-Adhesive capsulitis (controversial)
Thyroid acropachy manifestations
Soft tissue hand swelling
-Metacarpal and Phalangeal: clubbing & PERIOSTITIS
Thyroid acropachy associated withwhich thyroid disease
Graves
