22
Q

What is myasthenia gravis

A

Autoimmune destruction of ACh receptors characterized by fluctuating proximal muscle weakness, ocular symptoms and bulbar symptoms

23
Q

Differnce between myasthenic crisis and cholinergic crisis

A

Myasthenic crisis is acute worsening of symptoms due to infection, stress or UNDER medication

Cholinergic crisis is activation of cholinoreceptors (skeletal muscle weakness and parasympathetic signs) due to OVER medication

24
Q

How does edrophonium dicferentiate myasthenic crisis from cholinergic crisis?
