Myasthenia Gravis Research Paper

4. Neostigmine is one drug that may be prescribed for people with myasthenia gravis. This drug, like the edrophonium chloride injection, will make Annie feel stronger. Go back to the flow diagram, look at each stage, and determine how these drugs could work to increase synaptic performance.

Although patients can be preliminarily diagnosed with the syndrome based on an analysis of the physical symptoms, two tests can be used to confirm the diagnosis of GBS. The first is a lumbar puncture, or spinal tap, in order to obtain a small amount of spinal fluid for analysis. The spinal fluid of those with GBS often contains more protein than usual. The second is an electromyogram (EMG), which is an electrical measure of nerve conduction and muscle activity. (3) (4) The symptoms of GBS begin with numbness and tingling in the fingers and toes leading to weakness in the arms, legs, face, and breathing muscles. The weakness begins in the lower portion of the body and rapidly moves upward. This weakness eventually leads to loss of sensation in the affected areas; although a number of cases are mild, temporary limb paralysis is not uncommon. In the milder cases, the numbness can only cause difficulty in walking, "requiring sticks, crutches, or a walking frame." (3) Pain is not uncommon, and abnormal sensations, such as the feeling of "pins-and-needles," can affect both sides of the body equally. Loss

Myasthenia Gravis (MG) is a chronic autoimmune disorder of the neuromuscular system part of the body. Chronic means persisting for a long time or constantly recurring. Autoimmune disorder is the confusion of the body’s immune system. The immune system form antibodies that mistakenly identify healthy tissue as foreign and then, the antibodies will attack and/or destroy healthy body tissue. Neuromuscular is the nervous system relationship with the muscles bring about body movement.

Enzyme tests scan for high levels of CK (creatine kinase), that would point to a muscle disease. Enzymes such as CK are typically released by damaged muscles into the bloodstream. Electromyography measures the electrical activity in your muscles as they tighten and relax with an electrode needle; variations in the pattern of electrical activity can affirm a muscle disease. Because Duchenne is a genetic disease, genetic testing is sometimes used; blood samples will be inspected for mutations in some of the genes that can cause different types of muscular dystrophy, DMD in this case. Next, a little piece of muscle may be removed during a muscle biopsy through an incision or hollow needle. The biopsy is able to distinguish muscular dystrophies from other muscle diseases. Lung monitoring and heart monitoring tests may also be

After muscle injury physicians usually do blood or urine test to find an unexpected rise in serum CK levels, phosphate or aspartate transaminase. Medical professionals usually do a neuromuscular examination focusing on extremities to find physical clues such as color, pulse, sensation, muscle power, and size. The main focus would be size, muscle power, sensation and sometimes color. The muscles can be swollen causing an increase in size of the muscles within the arms and/or the legs. Intense pain within muscles of the arms and/or legs will show definite signs of sensation. Also, weakness in muscles will be another sign of loss of skeletal muscles and muscle power. Signs of Bruises that will leave a bluish purple or red color. These clues will show signs of muscle injury. A urine test that is commonly used by certain medical professionals to indicate signs of myoglobin is called Orthotolidine-toluidine dipstick test (Hisahara et. al,

Guillain-Barre syndrome is diagnosed in a couple ways however due to the fact that a great many of the signs and symptoms can be quite varied doctors have a hard time diagnosing it in the earliest stages. As previously stated several disorders have similar symptoms to Guillain-Barre syndrome so with many cases of this disease the doctors ensure that they get a very thorough examination as well as question the patients with great credibility before giving a diagnosis of this disease. Doctors normally give patients that think they have Guillain-Barre a nerve conduction velocity test this gives clues to the doctors that help aid in diagnosis. With some doctors they go to the extreme and perform a spinal tap to be for certain that a patient does in fact have Guillain-Barre Syndrome. A spinal tap is a procedure where a large needle is inserted into the lumbar (lower back) and a small amount of fluid is drawn, this fluid is cerebrospinal fluid. As of right now those are the only test to diagnose a patient.

Myasthenia gravis (MG) is an autoimmune disease which is related to a progressive inability to exert maintained or repeated contraction of striated muscles. B lymphocytes produce autoantibodies which act against the post-synaptic nicotinic acetylcholine receptors (AChR). The unusual activity of these B lymphocytes can be explained by the fact that they are not properly controlled by T lymphocytes due to a disorder present in the thymus gland (Xiu, Horton-Szar and Lucas, 2012). The T lymphocytes involved in damaging the acetylcholine receptors are the main cause of the pathogenis present with MG because they modify the synthesis of the high-affinity antibodies. This therefore triggers the loss of Ach receptors which results in damage of the neuromuscular junction (NMJ). Neuromuscular transmission is affected

With myopathies, some possibilities that could cause this disease to occur are metabolic disorders, adverse reactions to drugs, or autoimmune disorders (“Myopathy” 1). Multiple forms of myopathy can suggest that polymyositis might be genetic. To diagnose this disease in a person, the doctor will conduct blood tests, muscle and skin biopsy, electro-diagnostic tests, antibody testing. During blood test, the doctor will examine the blood for any increase of muscle enzymes. The muscle and skin biopsy will reveal any abnormalities such as damage, or inflammation in the sample. An MRI can allow the doctor to see any inflammation in the body (“Polymyositis (PM)” 1). Although there is no cure for this disease, its symptoms can be remedied with physical therapy to strengthen atrophied muscles and medication to suppress further inflammation in the muscles. Examples of medication are azathioprine and methotrexate which are types of immunosuppressant drugs (“Polymyositis (PM)” 1). A forty-three-year-old soul-jazz singer named William Downing suffered from this disease. He was interviewed by Jet Magazine about his illness and he described his life ever since he was drastically affected by

Myasthenia gravis is a disease that affects voluntary muscles of the body; it causes the weakening of the muscles. In this essay we will talk about how to treat myasthenia gravis, the symptoms and causes

1st motor neurons that release the neurotransmitter acetylcholine at the neuromuscular juntion, which then binds to nicotinic acetylcholine receptors on the muscle cell membranes. Binding of accetylcholine to its to its receptor activates a chain raction in the muscle cell that then produces a muscle contraction. In the body of those with myasthenia gravis (categorized as a type II hypersensitivity disorder) which causes cytotoxic injury meaning that it results in the lysis, or death of host cells, which is mediated by autoantibodies, antibodies that are ment for our own cells or proteins. 1.44 patients b cells ( DJFJDS) inappropriately make antibodies that bind to nicotinic acetylcholine receptors on the muscle cells. When the

Myasthenia gravis is an autoimmune neuromuscular disorder that annihilation the functional acetylcholine receptors at the neuromuscular joints. Normally, acetylcholine is used in signal transmission between nerves and muscles, its goal is to provide muscle contractions. But in this case, the decreasing

Test and diagnosis for Bell’s palsy. There is no specific test but your provider may look at your face and ask you to move your facial muscles to close your eyes lift your brow, showing your teeth and frown among other movements. These symptoms can also be related to other conditions such as Stroke, infection, Lyme disease and tumor’s. If your provider is unclear why you’re having symptoms they may recommend other test be performed like Electromyography (EMG) or Imaging Scans.

The immunopathogenesis of Guillain-Barré syndrome can be identified as three different subtypes. Acute inflammatory demyelinating polyneuropathy (AIDSP) is the most common form of Guillain-Barré syndrome, accounting for more than 85-90% of cases in which the immune target is within the myelin or Schwann cell surface membrane (Satoshi 2004). Lymphocytes infiltrate the peripheral nerves and macrophages invade and attack Schwann cells (Nobuhiro 2001). This leads to blockage or slowing of conduction within peripheral nerves, which results in muscle weakness. Acute motor axonal neuropathy (AMAN) results in axonal degeneration of motor fibers without hindering myelin (Satoshi 2004). AMAN is usually triggered by Campylobacter jejuni, an infection by which the induction of antibodies cross-react with gangliosides on the peripheral axons. This can be distinguished from AIDSP in that only selective motor nerves and axonal involvement and damage is indicated (Winer 2008). Acute motor and sensory axonal neuropathy (AMSAN) is a more severe subtype of Guillain-Barré syndrome that shows the same symptoms of AMAN but with axonal degeneration to both motor and sensory nerves (Nobuhiro 2001). This incidence of Guillain-Barré syndrome is very rare, being less than ten percent of that

My response is that the drug, edrophonium chloride (Tensilon) is used for a procedure called the Tensilon Test. This test helps differentiate what type of crisis you could have with myasthenia gravis. The two different types are myasthenia crisis and cholinergic crisis and it is important to differentiate the two to prevent and diagnose further complications. During the Tensilon test you would be given edrophonium chloride intravenously and if you start to notice that your symptoms, such as your droopy eyelid, have reduce this would be considered as a myasthenic crisis. It is when the edrophonium chloride has reduced your symptoms. If the edrophonium chloride that has been given worsens your symptoms that would mean you have a cholinergic crisis

On carrying out of special tests, Myotomes were positive for triceps weakness and dermatomes were positive for tingling at C6 level on right. Upper limb tension tests (ULTTs) were carried out with ULTT1 and ULTT2a positive due to pins and needle
