A tensilon test, also called an edrophonium test, is a pharmacological test used for the diagnosis of certain neural diseases, especially myasthenia gravis. [1] It is also used to distinguish a myasthenic crisis from a cholinergic crisis in individuals undergoing treatment for myasthenia gravis.
diagnosis of ocular myasthenia gravis Bienfang's test is a clinical test used in the diagnosis of ocular myasthenia gravis . It is used in conjunction with other examination techniques such as Cogan's lid twitch test [ 1 ] or enhancement of blepharoptosis from prolonged upward gaze.
Myasthenia gravis affects 50 to 200 people per million. [3] [4] It is newly diagnosed in 3 to 30 people per million each year. [13] Diagnosis has become more common due to increased awareness. [13] Myasthenia gravis most commonly occurs in women under the age of 40 and in men over the age of 60. [1] [5] [14] It is uncommon in children. [1]

Repetitive nerve stimulation is a variant of the nerve conduction study where electrical stimulation is delivered to a motor nerve repeatedly several times per second. By observing the change in the muscle electrical response (CMAP) after several stimulations, a physician can assess for the presence of a neuromuscular junction disease, and differentiate between presynaptic and postsynaptic ...
Transient neonatal myasthenia gravis is a very rare condition in which a mother with myasthenia gravis passes down her myasthenia gravis-inducing antibodies to her fetus through the placenta, causing the fetus to be born with antibodies that attach to self-antigens at the neuromuscular junction.(reference 12) Most cases of transient neonatal ...
About Myasthenia Gravis Myasthenia gravis (MG) is a chronic autoimmune disorder that causes disabling muscle weakness and fatigue. For most people with MG, the disease is characterized by the presence of antibodies against the acetylcholine receptor, a protein found on the surface of nerve cells that plays a key role in muscle contraction.
Antibodies against proteins in the neuromuscular junction of skeletal muscles made by a mother with myasthenia gravis and passed from her blood to her fetus's blood: Diagnostic method: Classic symptoms of transient neonatal myasthenia gravies in the offspring of mothers who have myasthenia gravis: Differential diagnosis
