Zvichitevera kuferefetwa kwakabatana kwakaitwa ne Indian National Center for Disease Control (NCDC) neUS CDC muMuzaffarpur, Bihar (uko kwakafa mazana evana muna Chivabvu naChikumi panguva yekukohwa maruva), zviremera zvehutano hweveruzhinji zvakadzika mitemo mitatu yemhuri yakaderedza kufa nepamusoro. 80%: 1. Usambofa wakarega vana vachirara vasina kudya chikafu chemanheru chakabikwa (chisvusvuro): Kudya chikafu chemanheru chine makabhohaidhiretsi kunozadza zvitoro zvine glycogen muropa kuitira kuti chiropa chemwana chisambofanira kuvimba nefatty acid yakavharika beta-oxidation usiku hwose. 2. Deredzai huwandu hwemalychees anodyiwa nevana vadiki, uye dzivirirai michero isina kuibva/yakawa: Musarega vana vachidya marimu asina kuibva kana hafu kubva pasi muminda yemichero, sezvo malychee asina kuibva aine zvinopfuura zvakapetwa kaviri zveMCPG neHypoglycin A inowanikwa mumuchero mutsvuku wakaibva zvakazara. 3. Ipa shuga yemumuromo nekukurumidza uye mhanyisa kukiriniki ine 10% Dextrose pachiratidzo chemangwanani chekutanga: Chero mwana ari munharaunda yelychee kana ackee anomuka achirutsa, akaneta, kana kuputika anofanira kugamuchira **10% Dextrose ** mukati meawa yekutanga (administering D10W within 4 hours of symptom onset reduces fatality from > 44% to < 5%)

Yenharaunda emergency uye chepfu control protocol

  • Jamaica neCaribbean: Fonera 119 (Jamaica Ambulance / Mapurisa) kana 911 / 999 (mhiri kwenharaunda dzeCaribbean) uye mhanyisa nekukasika kudhipatimendi rechipatara riri pedyo kunopinzwa mutsinga. 10% Dextrose.

Mibvunzo inowanzo bvunzwa

Sei vana vakaiswa muchetura nelychees kana kuti ackee isina kuibva vachiwanzorwara mangwanani-ngwanani?

Hypoglycin A neMCPG inovharira maenzayimu emitochondrial anodiwa kupisa mafuta emuviri uye kugadzira shuga itsva (gluconeogenesis), asi haamise chiropa kuburitsa glycogen yagara yachengetwa. Apo mwana anodya ackee isina kuibva kana kudya lychees uye anoenda kunorara pasina kudya kwemanheru, chiropa chavo chakachengetwa glycogen chinochengeta shuga yavo yeropa yakajairika kwemaawa mana kusvika ku10 ekutanga; pakati pe3:00 AM na8:00 AM, chiropa cheglycogen chinopera zvachose, zvichiita kuti shuga yeropa iparare pasi pe20 mg/dL nepo muchetura mafuta acid ari pakati achizadza uropi.

Sei jekiseni reGlucagon rekukurumidzira risingashande Ackee kana Lychee hypoglycemia?

Glucagon inosimudza shuga yeropa chete nekuraira chiropa kuti iparadze glycogen yakachengetwa uye kugadzira shuga itsva kuburikidza negluconeogenesis. Mu ackee uye lychee chepfu, chiropa chemurwere glycogen inenge yatove isina zvachose uye gluconeogenic enzymes yavo yakavharwa biochemically neMCPA-CoA uye MCPF-CoA, zvinoreva kuti glucagon ine zero effect; murwere anofanira kugamuchira zvakananga shuga yemuromo (kana akamuka) kana intravenous 10% Dextrose.

Nei Valproic Acid (Depakote) ine njodzi yekubatwa nepfari inokonzerwa neAckee kana Lychee chepfu?

Valproic acid inonzi branched-chain fatty acid iyo pachayo inoshandisa mitochondrial L-carnitine, inhibits fatty acid beta-oxidation enzymes, uye inosimudzira ropa ammonia. Kupa valproic acid kumurwere ane beta-oxidation nzira yakatove nechepfu neHypoglycin A kana MCPG inokanganisa zvakanyanya metabolic acidosis, hyperammonemia, uye inouraya cerebral edema; varapi vanofanira kushandisa benzodiazepines, levetiracetam (Keppra), kana phenobarbital pamwe chete ne10% Dextrose panzvimbo.

Ungaziva sei kana muchero mutsva weAckee wakachengeteka kunhonga nekubika?

Ackee pod nyowani inochengetedzeka chete kana yakatsvuka uye yero-orenji uye yakatsemuka yakavhurika zvakasununguka ("yawned") ichiri kurembera pamuti muzuva, ichinyatsoburitsa mhodzi nhatu nhema dzinopenya. Usambofa wakabika podhi yakasvibirira isina kuvhurwa, usambomanikidza podhi kuvhurika nebanga, gara uchibvisa mhodzi nhema uye yese yepingi-tsvuku membrane, uye gara uchidurura mvura iri kufashaira pasi mudhini.

Sei vanachiremba vachichengeta 10% Dextrose IV drip ichimhanya kwemaawa makumi maviri nemana kusvika makumi mana nemasere kunyangwe shuga yeropa yadzokera kune yakajairika?

Kupa imwe bolus yeglucose inogadzirisa shuga yakaderera yeropa kwemaminetsi makumi maviri kusvika makumi matatu chete. Kumhanyisa kuenderera kwepamusoro-mwero we10% Dextrose infusion (pa6 kusvika 8 mg/kg/miniti) inoita kuti shuga yeropa irambe yakakwira zvishoma (100 kusvika 150 mg/dL), iyo inomutsa insulin yemurwere pachake kuvhara kuparara kwemafuta muadipose tissue uye inomisa muviri kugadzira mamwe neurotoxic short-chain organic organic acids kusvikira liver organic acids yapora.

Mabhiza nembwa zvakare ane muchetura neHypoglycin A uye MCPG kubva kumbeu yemuti here?

Hongu, mabhiza anofura mumafuro munguva yematsutso nechirimo anowanzo rwara nechirwere chinouraya chinodaidzwa kuti Equine Atypical Myopathy (muEurope/UK) kana Seasonal Pasture Myopathy (kuNorth America) mushure mekudya mhodzi dzine mapapiro ("helicopter samaras") nemhodzi dzeSycamore Maple (Acer pseudoplatanus) uye Bhokisi Neguceapinda semiti imwe chete yemhuri yeApinda ackee uye lychee uye ine yakakwirira yeHypoglycin A.

Kuti upindure zvinobudirira kune zvechimbichimbi zvevana, metabolic, uye chepfu, funga kutora maoko-parubatsiro rwekutanga uye CPR kosi kubva kuRed Cross, St John Ambulance, kana wemuno kudzidziswa kwekukurumidza.
