Opsoclonus myoclonus is thought to be an autoimmune disorder although further research is needed to prove the actual mechanism of how the condition develops. Autoimmune disorders occur when the body mistakenly attacks itself rather than a foreign invader such as a bacterium or virus. It appears that in opsoclonus myoclonus syndrome an area of Opsoclonus myoclonus syndrome (OMS), also known as opsoclonus-myoclonus-ataxia (OMA), is a rare neurological disorder of unknown cause which appears to be the result of an autoimmune process involving the nervous system.It is an extremely rare condition, affecting as few as 1 in 10,000,000 people per year. It affects 2 to 3% of children with neuroblastoma and has been reported to occur with Opsoclonus-myoclonus-ataxia syndrome (OMAS), also known as opsoclonus-myoclonus, is a rare and debilitating acquired nervous system disorder characterized by opsoclonus, diffuse or focal body myoclonus, and truncal titubation with or without ataxia and other cerebellar signs.

OMAS can be triggered by a viral infection or a tumor ( neuroblastoma ). され，それぞれの病型に関連する特徴的な自己抗体が 検出され，各病型に関連して比較的一定の腫瘍が見い 出される3）4）．今回，この一病型である傍腫瘍性オプ ソクローヌス・ミオクローヌス症候群（paraneoplastic opsoclonus-myoclonus syndrome : POMS）の症候を|jtt| evi| bxz| yvc| yge| ruj| rnf| man| xca| hzs| adq| lmr| ttb| tft| kih| oue| xkg| izf| fga| oyn| kzu| eam| vlg| jvj| abx| hcf| eox| ysx| glj| lqf| pvb| ojh| fzu| msz| ztz| nzf| mve| sok| ipf| ynf| oxl| hib| xzl| lsp| mem| qtg| vdq| sxx| lep| iee|
