Mafunso omwe amafunsidwa pafupipafupi¶

Kodi "Ngozi ya Triangle ya Nkhope" ndi chiyani, ndipo n'chifukwa chiyani kufinya pimple kumeneko kungayambitse magazi muubongo?¶

"Danger Triangle of the Face" ndi gawo la katatu lomwe likuyenda kuchokera pa mlatho wa mphuno kupita kumanzere ndi kumanja kwa pakamwa panu, kuphatikizapo mphuno, mphuno, ndi milomo yakumtunda. Mosiyana ndi mitsempha ya m'thupi lanu lonse yomwe ili ndi ma valve olowera njira imodzi kuti magazi aziyenda molunjika ku mtima wanu, mtsempha wa kumaso (angular vein) ndi mitsempha ya pamwamba ndi yotsika kwambiri ya maso anu ili ndi ziro valves. Mukafinya kapena kutulutsa chithupsa chakuya kapena pimple (yomwe imakhala ndi Staphylococcus aureus) mkati mwa mphuno kapena kumtunda kwa mlomo, kutupa kozungulira kumatsekereza ngalande yotsika, ndipo kufinya kumakankhira magazi omwe ali ndi kachilombo ndi mabakiteriya kumbuyo kudzera m'mitsempha yamaso molunjika mumphako m'munsi mwa ubongo.

Chifukwa chiyani kulephera kutembenuza diso limodzi kunja ("sixth-nerve palsy") ndi chizindikiro choyambirira cha cavernous sinus thrombosis?¶

Mitsempha isanu ya cranial imadutsa mumphako panjira yopita ku diso ndi kumaso: Mitsempha ya Cranial III, IV, V1, ndi V2 imasungidwa bwino mkati mwa khoma lolimba lakunja kwa sinus, pomwe Cranial Nerve VI (mitsempha ya abducens, yomwe imayendetsa minyewa yomwe imatembenuza diso lako kunja kupita mkatikati mwa dziwe lamkati lomwe limayandama) mitsempha ya carotid. Pamene mabakiteriya ndi magazi kuundana poyamba kulowa cavernous sinus, Cranial Nerve VI ndi mitsempha yoyamba kusamba ndi mafinya ndi kupanikizika. Wodwala yemwe ali ndi matenda a sinus kapena chithupsa cha nkhope ndipo mwadzidzidzi amayamba masomphenya opingasa awiri chifukwa diso limodzi silingatembenuke kunja likufunika MRI/MRV ndi IV mankhwala mwamsanga.

Kodi madotolo amasiyanitsa bwanji pakati pa orbital cellulitis ndi cavernous sinus thrombosis?¶

Ngakhale kuti zonsezi zingayambitse diso lofiira, kutupa, lotupa (proptosis), kutentha thupi, ndi kusuntha kwa diso kowawa kapena kosalekeza, zizindikiro zitatu zimaloza makamaka ku cavernous sinus thrombosis: (1) Kufalikira kwa mbali ziwiri: chifukwa kumanzere ndi kumanja kwapang'ono kumalumikizidwa kudutsa pakati ndi mitsempha yodutsana, kutupa ndi kupuwala kwa diso kumalumpha moyang'anizana ndi diso loyamba la 48; (2) Trigeminal mitsempha dzanzi: kukanikiza kapena kukhudza pang'ono pamphumi pa wodwalayo (CN V1) kapena tsaya lapamwamba (CN V2) kumasonyeza dzanzi kapena kutaya kwa cornea blink reflex; ndi (3) Kuopsa koopsa kwa minyewa, kuphatikizapo kupweteka kwa mutu kuseri kwa maso, kuuma khosi, mwana wotumbululuka/ulesi, ndi kusuntha kwa maso oundana mosagwirizana ndi kutupa kwa chikope.

Kodi chomwe chikuyambitsa #1 cha septic cavernous sinus thrombosis masiku ano ndi chiyani ngati sichikufinya ziphuphu?¶

Asanatulukire maantibayotiki, kufinya zithupsa kumaso ndi m'mphuno ("furuncles") mkati mwa Danger Triangle ndizomwe zimayambitsa cavernous sinus thrombosis. Masiku ano, ngakhale zithupsa za m'mphuno zimachititsabe 15 mpaka 25 peresenti ya milandu, chifukwa # 1 yamakono (yomwe ili ndi 50 mpaka 60 peresenti ya milandu) ndi bakiteriya sphenoid sinusitis ndi ethmoid sinusitis. Chifukwa sphenoid sinus imakhala pansi kuseri kwa mphuno yolekanitsidwa ndi mphako ndi khoma la mafupa ochepera 0.5 millimeters woonda (omwe nthawi zambiri amakhala ndi mipata yaying'ono), kachilombo koyambitsa matenda kozama kopanda chithandizo kamatha kulowa mu mphako.

Chifukwa chiyani madotolo amapereka mankhwala ochepetsa magazi (Heparin) kuti atseke magazi omwe ali ndi kachilombo mkati mwa cavernous sinus?¶

Poyang'ana koyamba, kupereka magazi ochepa kwambiri panthawi ya matenda kumamveka koopsa, chifukwa chake madokotala amayamba kupanga CT ndi MRI scan kuti atsimikizire kuti palibe magazi omwe akugwira ntchito muubongo. Kutuluka kwa magazi kumachotsedwa, mtsempha wa heparin (kapena heparin yotsika kwambiri) pamodzi ndi mankhwala opha tizilombo toyambitsa matenda amatenga gawo lofunika kwambiri lopulumutsa moyo: imalepheretsa kufalikira kwa magazi m'mitsempha yamkati mwa diso lina la wodwalayo kapena kubwerera kumbuyo mu ubongo wonse wa ubongo, kutsekereza mitsempha yamkati, kutsekereza mitsempha yamkati, kutsekereza mitsempha yamkati, kutsekeka ndi kutsekeka kwa mitsempha. imasunga mayendedwe otseguka kotero kuti maantibayotiki amatha kulowa m'thupi.

Kodi ndingatani ngati ndili ndi chithupsa chowawa m'mphuno mwanga kapena pamlomo wanga wakumwamba pompano?¶

Choyamba, sungani manja anu pa izo: musamafinya, kutsina, kusankha, kapena kupukuta ndi singano. Ikani nsalu yochapira yoyera, yofunda, yonyowa pang'onopang'ono pamalopo kwa mphindi 15 katatu kapena kanayi pa tsiku kuti mulimbikitse ngalande zakunja popanda kukakamizidwa. Onani dokotala tsiku lomwelo kuti mupeze mankhwala opangira mankhwala a mupirocin (2%) a m'mphuno ndi maantibayotiki apakamwa omwe amaphimba Staphylococcus aureus (ndi MRSA ngati amapezeka m'dera lanu). Ngati mukudwala malungo, kufalikira kufinya mkati mwa diso lanu lamkati, mutu kuseri kwa maso anu, kutupa kwa zikope, kapena kuwona kawiri, pitani kuchipatala chachipatala.
