PT - Peripheral neuropathy Flashcards
Erythema chronicum migrans
Target-shaped lesions that enlarges as the central area returns to normal seen in Lyme disease.
Antibiotic management of Lyme disease.
Ceftriaxone and erythromycin
Common characteristics of chronic Lyme.
Erythema chronicum migrans Chronic meningitis Arthralgia Facial weakness Optic neuritis
Patellar reflex depends on what nerve root?
L3, L4 (L2?)
Lead poisoning in adults p/w?
Painless neuropathy, often targeting the radial nerve and resulting in wrist drop
Mono-neuropathy multiplex
Disorder where individual nerves are transiently disabled and can develop over course of mins to days 2/2 Diabetes.
Posterior cord of brachial plexus
Radial nerve, Axillary nerve
Medial cord of the brachial plexus
Ulnar nerve, Median nerve
Lateral cord of the brachial plexus
Musculocutaneous nerve, Median nerve
Likely to cause injury limited to upper brachial plexus (C5-C6).
Birth trauma ( lateral traction of neck during delivery causes Erb palsy or waiter’s tip so can’t abduct, laterally rotate, flex elbow + suppinate)
Likely to cause injury limited to lower brachial plexus.
Node dissections in axilla, Pancoast tumor
Prominent areas of degeneration in Fredreich ataxia.
Mostly spinocerebellar tracts then posterior columns, lateral corticospinal tracts.
3 major complications associated with Fredreich ataxia.
Diabetes mellitus
Hypertrophic cardiomyopathy
Kyphoscoliosis in childhood
Parsonage-Turner syndrome (brachial plexopathy)
AKA Brachial neuritis or neuralgic amyotrophy, begins with acute onset of neck/shoulder/upper arm pain –> proximal muscles rarely hands or respiratory muscles. Sensory loss also occurs. Cause unknown but 2/2 immunological or autoimmune response following vaccine or viral illness. Can be familial.
Familial Dystonia or Riley-Day disease
AR, Jewish children, small-fiber neuropathy affecting both myelinated and unmyelinated small fibers causing impairment of pain and temperature sensation as well as autonomic features (orthostatic hypotension).
