A

injury occurs to either: vertebrae & ligaments, blood vessels, damage to vertebrae ligaments, blood vessels makes spinal cord unstable incrasing possibility of compression or stretching of cord with further movement. rarely is spinal cord completely severed.

Q

autonomic dysreflexia

A

what is it?:
exaggerated sympathetic response in SCI patient at or above T6 injuries. triggered by stimult that normally causes abdominal pain.

pathophysiology: stimuli is unable to ascend the cord. causes stimulation of sympathetic nerves below level of injured cord resulting in massive vasoconstriction. vagus nerve causes bradycardia & vasodilation about level of injury.

47
Q

sever lupus: high dose coritocsteroids to manage symptoms & prevent organ damage. may need steroids long temr.

immunosuppressive meds: monitor infections, labs, kidney, & liver function.

49
Q

polymyositis

A

autoimmune systemic connective tissue disorder causing inflammation of connective tissue and muscle fibers.

50
Q

polymyositis risk factors

A

unknown cause. women > men

51
Q

polymyositis manifestations

A

skeletal muscle weakness is main symptom. pelvie and neck muscles particularly. muscle pain and tenderness. weakness progresses over weeks to months. dusky red rash on face and upper trunk.

52
Q

polymyositis diagnosis & treatment

A

no specific test for diagnosis, creatine kinase elevated 25-170 normal ranges.

rest, corticosteroids, immunosuppressive agents.

53
Q

Rheumatoid arthritis (RA)

A

chronic systemic autoimmune disease causing inflammation of connective tissure primarily in joints, cause unknown.

54
Q

RA risk factors

A

thought to be genetic, emotial stress cause flare ups, women 3:1 to men, heavy smoking, speculated that infectious agent such as a virus plays a role in initiating abnormal immune response.

55
Q

RA, clinical manifestations

A

joint swelling, stiffness, tenderness, warmth, ROM limited in affected joint. deformity of joints, joints feel sponge-like on palpation.

56
Q

RA diagnostic tests

A

elevated c-reactive protein & esr, anti CPA blood test, more specific marker for RA. synovial fluid from joint cloudy. xrays of joints most specific test for RA.

57
Q

RA treatment goals

A

no cure relieve pain, reduce inflammation, slow or stop joint damage, improve well-being and function.

58
Q

RA meds

A

NSAIDS & steroids reduce inflammation and pain, disease modifying anti-rheumatic drugs slow bone erosion, improve ROM, monitor for blood dyscrasias.

59
Q

RA treatment

A

PT & OT, assistive devies and splints. nutrition.
surgery
synovectomy: to relive pain and reduce inflammation, arthrodesis to stabilize joints wrists, ankles, cervical. arthroplasty imprved mobility decrease pain.
