Talk:Myasthenia gravis/Archive 1

Latest comment: 6 years ago by Metaquanta in topic Associated Conditions

The current editing and info on MG is terribly confusing and just too much “mumble jumble” for folks looking for more basic info.

I would recommend that an MG Specialist rewrite it or go on the MGNA website to get great, clearly written info.

In the meantime, Here is a good article to use as the introduction to the disease.

Myasthenia Gravis


Medically reviewed by Deborah Weatherspoon, PhD, RN, CRNA on April 23, 2018 — Written by Jaime Herndon Symptoms Causes Diagnosis Treatments Complications Outlook Myasthenia gravis Myasthenia gravis (MG) is a neuromuscular disorder that causes weakness in the skeletal muscles, which are the muscles your body uses for movement. It occurs when communication between nerve cells and muscles becomes impaired. This impairment prevents crucial muscle contractions from occurring, resulting in muscle weakness.

According to the Myasthenia Gravis Foundation of America, MG is the most common primary disorder of neuromuscular transmission. It’s a relatively rare condition that affects between 14 and 20 out of every 100,000 people in the United States.


What are the symptoms of myasthenia gravis? The main symptom of MG is weakness in the voluntary skeletal muscles, which are muscles under your control. The failure of muscles to contract normally occurs because they can’t respond to nerve impulses. Without proper transmission of the impulse, the communication between nerve and muscle is blocked and weakness results.

Weakness associated with MG typically gets worse with more activity and improves with rest. Symptoms of MG can include:

trouble talking problems walking up stairs or lifting objects facial paralysis difficulty breathing due to muscle weakness difficulty swallowing or chewing fatigue hoarse voice drooping of eyelids double vision Not everyone will have every symptom, and the degree of muscle weakness can change from day to day. The severity of the symptoms typically increases over time if left untreated.

What causes myasthenia gravis? MG is a neuromuscular disorder that’s usually caused by an autoimmune problem. Autoimmune disorders occur when your immune system mistakenly attacks healthy tissue. In this condition, antibodies, which are proteins that normally attack foreign, harmful substances in the body, attack the neuromuscular junction. Damage to the neuromuscular membrane reduces the effect of the neurotransmitter substance acetylcholine, which is a crucial substance for communication between nerve cells and muscles. This results in muscle weakness.

The exact cause of this autoimmune reaction is unclear to scientists. According to the Muscular Dystrophy Association, one theory is that certain viral or bacterial proteins may prompt the body to attack acetylcholine.

According to the National Institutes of Health, MG typically occurs in people over the age of 40. Women are more likely to be diagnosed as younger adults, whereas men are more likely to be diagnosed at 60 or older.

Congenital Myasthenic Syndrome

edit

It is extremely important to edit CMS out of this article and to have a separate article on CMS. MG is an autoimmune disease, CMS is genetic. Two totally different classes of disease. They have a diffent etiology and therefore, except for some shared symptoms, nothing in common and should not be confused. In fact, CMS patients benefit from a clear distinction, as there are notable differences in medicating both diseases. —Preceding unsigned comment added by 78.53.120.173 (talk) 21:58, 27 June 2008 (UTC)Reply

We (now) have Congenital myasthenic syndrome but the MG lead still says "Alternatively, in a much rarer form, muscle weakness is caused by a genetic defect in some portion of the neuromuscular junction that is inherited at birth..." which sounds like CMS since it is not auto-immune. Can we clarify if the genetic form mentioned is CMS, and if it is a subtype of MG ? - Rod57 (talk) 14:00, 18 November 2015 (UTC)Reply

Help

edit

Answer:

Dear Freazer,

I consulted several experts and the original author when improving the article. I suggest we collaborate to make a good article, in stead of reverting to older versions. For most changes i made i had good reasons, so perhaps you can discuss any changes you don't agree with, in stead of undoing all the effort that was put in it. It is very unfortunate that the article became victim to vandalism since february 1st so i suggest we both try to keep it vandalism-free. Perhaps we the wiki group can make editing members-only. Anyway, my changes were not vandalism.

The reason i added section you mentioned: As i see it, this article is intended to give information to people who want information about myasthenia gravis. That will mostly be patients, their friends and relatives and doctors, nurses and researchers. I also added a lot of information useful for doctors and researchers. But to patients thís is very useful info, and imo adding info like this makes the wiki better than any other encyclopedia. Because it actually answers one's questions. Nevertheless i left the section out, since it especially seemed to bother you. Hope to hear from you soon.

I doubt this

edit

The article says: Applying ice to the weak muscle groups may characteristically improve the weakness. Is this true?

Yes, this factlet is specifically supported by the Scherer reference. JFW | T@lk 13:26, 22 December 2005 (UTC)Reply
Yes, cooling increases the sensitivity of the postjunctional membrane to acetylcholine and decreases cholinesterase activity. (Nerve conduction speed and acetylcholine release are decreased by cooling and these adversely affects neuromuscular transmission. This, however, is partially counteracted by decreased muscle-ChE activity and increased sensitivity of the postjunctional membrane to ACh caused by cooling. In MG patients these last two effects have a much greater effect than in healthy individuals and neuromuscular transmission actually improves.

Myasthenia is derived from Greek; Gravis is from Latin

From the top of the page:

Myasthenia gravis (MG, Latin: "grave muscle weakness")

See

Re-write of Prognosis section

edit

First, I wish to declare my bias, so you can call me on it if I let it affect my contributions. I have a friend who's been diagnosed with MG and her friends are visiting wikipedia for a quick summary. Unfortunately, the "Prognosis" section gives the impression MG is completely treatable, which is not true. When I went digging I found the origins of the pronosis section:

With treatment, most patients have a near-normal quality of life and no significant problems. Some cases of myasthenia gravis may go into remission temporarily and muscle weakness may disappear completely so that medication can be discontinued. Stable, long-lasting complete remissions are the goal of thymectomy, although this cannot always be achieved. (Wikipedia, current version)

It appears to be based on a factsheet from the US government, aimed at patients:

With treatment, the outlook for most patients with myasthenia gravis is bright: they will have significant improvement of their muscle weakness and they can expect to lead normal or nearly normal lives. Some cases of myasthenia gravis may go into remission temporarily and muscle weakness may disappear completely so that medications can be discontinued. Stable, long-lasting complete remissions are the goal of thymectomy. In a few cases, the severe weakness of myasthenia gravis may cause a crisis (respiratory failure), which requires immediate emergency medical care. (see above). (Fact Sheet).

The fact sheet is careful not to alarm people, but the wikipedia entry omits all negative information. Overall, the wikipedia entry gives a very rosy picture. Now I'm going to try and re-write that section based on other sources.

I think from a doctor's perspective there are many worse, less treatable diseases. Especially from a neurologist's perspective. I agree it should not sound too optimistic. On the other hand i see a lot of patients that googeled their disease and then come to the doctor with their heads full of worst case scenario's. Sometimes to the point where these thoughts bother the patient even more than the disease itself! So it's always difficult to strike a balance. If the update i did on the english version is read and corrected, i'll translate it to Dutch. Pizzaman79 13:33, 13 December 2006 (UTC)Reply

Details

edit

This is a great article, but i think it misses some details here and there. Some examples...

- The autoimmune process is NOT fully clarified imho. First of al some of the patients don't carry AchR or MuSK antibodies. Since they do respond to immunosuppresive therapy they probably have some other, yet unknown, auto-immune process. Also, MG seems different from other autoimmune diseases. Some genetical variations (SNP's) seem to have effects opposite to other auto immune diseases, sometimes ascribed to T-cell maturation in the thymus.

- The stuff about ice is a very neat trivia. But a reader will think this is the common way doctors examine patients and it's not. So that should be clarified. What i miss is an explenation about which tests doctorsactually do. For example, just asking a patient to keep his arms stretched out (Barré style) will clearly show fatiguability of a muscle with otherwise good strength (usually 5/5). I have an book about MG by Oosterhuis, i should look up what he sais in his chapter about the physical exam.

- The part on the blood test could state more clearly that the diagnostical use of the test is limited. The ultimate test is a patient's response to immunosuppressive therapy, in my experience. Also, wasn't the antibody titer useful for followup? (i'd have to look that up)

- Pathophysiology: again too optimistic to my taste. Even when testing for MuSK there are still sero-negative patients and i believe the MuSK test is not something many hospitals offer. Without that you'll have quite a lot of seronegative patients. (i'm not even sure if the AchR test is that common)

- Epidemiology: do we have figures about congenital MG? Also there are two epidemiologic peaks: females in their 30's and males in their 50's and 60's. This suggests perhaps hormonal influence or two distinct entities and should therefor be mentioned.

- I think if you mention thymectomy and chest (thymus) CT's for thymoma imaging, you should also explain the correlation a little more thorough than "There are various theories that explain why thymoma may predispose to MG"

These are just some things that cought my eye in a first quick read. Since i'm suggesting a lot more than a few minor changes i suggest the original author can contact me so we can perhaps collaborate on a rewerite.

Edit: i contacted the original author and another person doing research on the topic. It may take some time, but i'll do a rewrite.

Edit2: I changed the article now. It didn't need as much changing as i first expected. One point of discussion remains: prevalence. I have a neurology book stating it is 40/million, whereas myasthenia.org says 20/100.000 is an underestimation! Who can find an authorative reference?

I think improvements can be made to the Neurophysiological changes associated with the disease. SteveD 16:08 13 April 2008.

As an MG patient, I would think that myasthenia.org would have more recent info, however, as it is with everything realted to MG, I think a 100% accurate info is not available. Bengisuk 10:53, 9 February 2007 (UTC)Reply

Agreed.

Good article nomination

edit

Here are my suggestions:

  • "At about 14 cases per 100,000 (in the U.S.), it is one of the lesser known autoimmune disorders." (reference?)
  • According to Wikipedia:Manual of Style (medicine-related articles), classification should be placed before Signs and symptoms.
  • "Often the physical examination is within normal limits." (a reference about an overview of the signs would be welcome)
  • "Often symptoms come and go. The diagnosis of myasthenia gravis is often initially missed." (I don't think it's a proper sentence, you can't write that symptoms come and go)
  • Reference for the classification?
  • Please follow the manual of style regarding the order of sections
  • and most of the diagnostic tests are unreferenced sections
  • external links in the sections should be converted into references (see Epidemiology)
  • I don't think we should include specific doses.

I've tried to incorporate all abovementioned suggestions. For this relatively rare disease it's tough to find good digital references for every stated fact, so i had to use one printed book.

Thymectomy survey

edit

I think this article would benefit from a mention of the large-scale survey into the effectiveness (or otherwise) of thymectomy, led by John Newsom-Davis until his recent sudden death. I was tempted to add something myself, but I think it would be better done by an expert in the field.

(interrupting my wikibreak for a few moments - I won't be able to respond again for a while) There are plenty of refs in the JN-D article, and I'm sure google will provide a few more. I expect it'll be a while before full results are published, but some mention of the scope of, and reasons for, the survey would, I think, be appropriate.

Pathophysiology section -revision of statements about normal physiology needed

edit

The fourth paragraph under "Pathophysiology" is factually incorrect:

"In normal muscle contraction, cumulative activation of the ACh receptor leads to influx of sodium and calcium. Only when the levels of these electrolytes inside the muscle cell is high enough will it contract. "

Not so. Each activation of the ACh receptor (at the neuromuscular junction by means of the ACh released by each arriving motor action potential) opens a sodium-potassium permeable 'non specific' ion channel. This leads to a depolarisation of the muscle fibre membrane under the motor end-plate. Calcium entry is not favoured by ACh, but critically the 'levels of these electrolytes' (be they sodium and potassium) are not appreciably altered. It is the (small) flux of the ions across the membranes that carries and electric current sufficient to depolarise that local region of membrane. The 'levels' (concentrations) of sodium and potassium are not altered appreciably as a result of one, or indeed many action potentials. The depolarisation triggers an action potential in the muscle fibre which, in turn, triggers the release of calcium from internal stores in the muscle fibre (the sarcoplasmic reticulum). The rise in calcium concentration is what favours contraction.

So the problem of the antagonism of the ACh receptor by antibodies is that the incoming action potential fails to depolarise the motor end plate and thus fails to trigger a new action potential in the muscle fibre. This means there is no response by the muscle to the nerve's activity and hence paralysis. Repeated action potentials may allow sufficient receptors to be activated sufficiently for a response (though it is thereby weakened). This outcome is favoured by the use of anticholinesterase agents which inhibit the breakdown of ACh. The offending antibodies may be competitively antagonised by ACh if it is at a high enough local concentration for long enough. DoctorCaffeine (talk) 13:46, 27 May 2008 (UTC)Reply

GA Review

edit
This review is transcluded from Talk:Myasthenia gravis/GA1. The edit link for this section can be used to add comments to the review.

This article does not meet the Good article criteria and has therefore failed. Issues include:

  • The lead is too short. Please expand it to better summarize the entire article, per WP:LEAD.
  • Too much information is unreferenced, including:
    • Most of "Signs and symptoms"
    • Entire " Pathophysiology" section
    • " Associations" section
    • Most of " Treatment" section
  • References are placed incorrectly; they should be after all punctuation marks with no spaces in between, per WP:FN.

Please renominate the article once these issues have been resolved. Gary King (talk) 05:51, 31 July 2008 (UTC)Reply

Some sections must go: associations is unsourced, and the content on pregnancy and children can be merged elsewhere.

dysarthria / dysphonia

edit

The former seems to have a more specific definition, however slightly more sources for this topic seem relate it to the latter. Matthew Ferguson (talk) 07:46, 12 July 2015 (UTC)Reply

Looking at both of the wikipedia articles, I would say that the myasthenia gravis sources using the term dysphonia are incorrect, so I think we should use dysarthria only. Matthew Ferguson (talk) 09:45, 12 July 2015 (UTC)Reply
@Matthew Ferguson 57: Dysarthria is where the voice changes due to facial muscle dysfunction, while in dysphonia it is the larynx/vocal cords. JFW | T@lk 10:27, 12 July 2015 (UTC)Reply
would you agree that dysarthria seems to be more relevant to this condition? Matthew Ferguson (talk) 15:47, 12 July 2015 (UTC)Reply
@Matthew Ferguson 57: Both are possible. Fatiguing bulbar/nasal dysarthria is characteristic in MG. If there is severe weakness (laryngeal and intercostal musculature) then the voice will be weak too. JFW | T@lk 18:04, 12 July 2015 (UTC)Reply

Apparent typo needs attention from a medical expert

edit

In the paragraph under SURGERY, the last three sentences (with my insertion of bold type,) are:

Surgery in the case of MG involves the removal of the thymus, although no clear consensus indicates it would be beneficial except in the presence of a thymoma. However, thymectomy should not be done in ocular myasthenia.[52] A 2016 randomized controlled trial found benefits from thymus removal for ocular MG.[53]

These two sentences are contradictory, and probably the word "no" should be inserted, so that the second phrase would read found no benefits from thymus removal. Please ask a medical professional to make a judgment about this.

Otherwise, this is a very well-written article. Janice Vian, Ph.D. (talk) 01:35, 30 October 2017 (UTC)Reply
