Central Pontine Myelinolysis | Osmotic Demyelination Syndrome
Ata: Central Pontine Myelinolysis | Osmotic Demyelination Syndrome

Osmotic demyelination syndrome (ODS) o le faiʻai sela le aoga. E mafua mai i le faʻaleagaina o le vaega (myelin sheath) ufiufi sela sela i le ogatotonu o le faiʻai (pons).

A o le myelin sheath e ufiufi neula sela ua faʻaleagaina, faʻailo mai le tasi neula i le isi e le lelei faʻasalalauina. E ui lava o le faiʻai e masani ona aʻafia, o isi vaega o le faiʻai e mafai foi ona aʻafia.

O le mafuaʻaga masani a le ODS o le vave suia i le tino o le sodium tulaga. O lenei mea e masani ona tupu pe a togafitia se tasi mo le maualalo o le toto sodium (hyponatremia) ma o le sodium e vave ona suia. O nisi taimi, e tupu pe a oʻo i se maualuga maualuga tulaga o sodium i le tino (hypernatremia) vave faʻasaʻo.

ODS e le masani ona tupu na o ia. Tele taimi, o se faʻafitauli o togafitiga mo isi faʻafitauli, pe mai isi faʻafitauli lava latou.

O aʻafiaga e aofia ai:

  • Faʻaaogaina o le 'ava malosi
  • Maʻi ole ate
  • Le lava mea taumafa mai maʻi tuga
  • Togafitiga o le faiʻai o le faiʻai
  • Faasoesa matuitui ma puaʻi i le taimi o maʻito

Faʻailoga mafai ono aofia ai soʻo se tasi o mea nei:


  • Le mautonu, le mautonu, faʻaaliga
  • Paleni faʻafitauli, gatete
  • Faafitauli folo
  • Faʻaitiitia le mataala, fia moe poʻo le moe, moe faʻaletonu, leaga tali
  • Tautalaga lemu
  • Vaivaiga i foliga, lima poʻo vae, e masani ona aʻafia uma itu o le tino

E faʻataʻitaʻi e le tausi soifua le suʻega o le tino ma fesili e uiga i faʻailoga.

O le ulu MRI faʻataʻitaʻi ono faʻaalia ai se faʻafitauli i le faiʻai (pons) poʻo isi vaega o le faiʻai. Ole suʻega autu lea.

O isi suʻega ono aofia ai:

  • Toto sodium tulaga ma isi toto suʻega
  • Brainstem auditory faʻaosofia tali (BAER)

ODS o se faʻalavelave faʻafuaseʻi e manaʻomia ona togafitia i le falemaʻi e ui o le toʻatele o tagata e maua i lenei maʻi ua uma ona i totonu o le falemaʻi mo se isi faʻafitauli.

E leai se iloa fofo mo tutotonu pontine myelinolysis. Togafitiga e taulaʻi ile faʻamama avega.

Ole faʻamalositino e mafai ona fesoasoani ile faʻamalosi ole maso, feʻaveaʻi, ma gaioiga ile lima ma vae ua vaivai.


O le neura faʻaleagaina mafua mai i le tutotonu pontine myelinolysis e masani ona umi-tumau. O le faʻamaʻi mafai ona mafua ai tuga tuga tumau (tumau).

Faʻafitauli e ono aofia ai:

  • Faʻaitiitia le mafai gafatia ma isi
  • Faʻaitiitia le mafai e galue pe tausi mo oe lava
  • Le mafai ona minoi, seʻi vagana ai le emo o ou mata ("lokaina i totonu" syndrome)
  • Faʻamaumau tumau le tino o le tino

E leai se taʻiala moni ile taimi e suʻe ai togafitiga faʻafomaʻi, aua e seasea maua le ODS ile lautele lautele.

I le falemaʻi, lemu, faʻatonutonu togafitiga o se maualalo sodium tulaga ono faʻaititia le lamatiaga mo neura faʻaleagaina i le pons.O le nofouta pe faʻafefea e nisi vailaʻau mafai ona suia sodium tulaga mafai puipuia ai le tulaga mai suiga vave.
