- s/s
Degeneration of axon Linder and myelin d/t inability of neuronal body to keep up w/ metabolic demands of axon.
Develops in the most distal part of the axon,
S/s: characteristic distal sensory loss + weakness
77
Myasthenia gravis:
- defined
- effects
- Rx:
Autoimmune attach of Ach receptor at the NMJ: signal can' travel from nerve to mm.
Effects:
Progressive mm weakness: decreased cardioresp, atrophy, fatigue
Rx:
Medication to prevent Ach breakdown at NMJ
- activity within tolerance, prevent secondary conditions.
78
Charcot Marie tooth Disease
- defined
- s/s
- Rx
Hereditary neuropathy causing extensive demyelination of motor and sensory nerves of foot
S/s:
- symmetrical mm weakness w/ slow progression + foot mm atrophy, decrease DF, everter mm.
- decreased deep tendon reflex
- Pes cavus (hammer toes)
Rx: stretching for contracture management + foot care
79
Bell's Palsy:
- defined
- s/s
- Rx
Latent herpes virus causes inflammation response over facial nerve.
S/s: unilateral facial paralysis:
- decreased: facial expressions, shaped ius mm of inner ear, sensory + autonomic taste fibers, tears, saliva
Rx: Cortico steroids, protect eye
80
Thoracic outlet syndrome:
- defined
- s/s
Entrapment due to pressure on brachial plexus:
- chronic compression caused edema, ischmia of nerve roots, neuropraxia + Wallachian degeneration
S/s:
- paraesthesia, UE weakness, pain, hand fatigue, neck pain, Raynaud's, edema
81
Diabetic neuropathy:
- defined
- pathology
- s/s
- Rx
- perioheral vascular disorder in diabetes occuring w/o any other neuropathy cause
Chronic metabilic disturbance --> affects nerves + Schwann cells resulting in loss of both myelinated and unmyelinated axons
S/s:
- symmetric + distal sensory loss
- painless paraesthesia
- minimal motor weakness
Rx: control hyperglycemia, skin care, amputation
82
Scars:
| - types and features
Keloid:
- thick scar: extends beyond margins of original wound
Hypertrophic:
- thick scar: excess tissue but within border of original wound
