Chitani izi tsopano¶

1. *Imbani foni nambala yanu yadzidzidzi nthawi yomweyo ngati wodwala khansa, hyperparathyroidism, kapena matenda a granulomatous ayamba chisokonezo, kugona kwambiri, kusanza kosatha, kapena kufooka kwambiri. Imbani 911 ku United States ndi Canada, 999 ku United Kingdom, 112 kudutsa European Union, 000 ku Australia, kapena fufuzani bukhu lathu la manambala angozi. Hypercalcemia yoopsa imayamba msanga kuchoka ku kulefuka ndi kulankhula momveka mpaka kukomoka, kulephera kwaimpso, ndi kumangidwa kwadzidzidzi kwa bradycardic/ventricular cardiac.
2. Imitsani nthawi yomweyo mankhwala onse owonjezera kashiamu ndi zowonjezera panyumba ndi mchipatala:
3. Imitsani zonse zowonjezera calcium mkamwa, calcium carbonate antacids (Tums, Rennie, Rolaids), ndi Vitamini D/calcitriol supplements.

Mafunso omwe amafunsidwa pafupipafupi¶

N’chifukwa chiyani kashiamu wochuluka m’magazi amapangitsa munthu kutaya madzi m’thupi kwambiri ngati akukodza tsiku lonse?¶

Kashiamu wochuluka m'magazi amawononga mwachindunji makina odzaza madzi a impso, zomwe zimayambitsa matenda otchedwa calcium-induced nephrogenic diabetes insipidus. Makamaka, calcium yochulukirapo imayendetsa zolandilira calcium mu Loop of Henle (kuchita ngati diuretic yosayimitsa yomwe imataya mchere ndi madzi) ndikutchinga njira zamadzi za Aquaporin-2 m'mitsempha yosonkhanitsira kuti impso zisayankhenso ku antidiuretic hormone (ADH). Zotsatira zake, wodwalayo amakodza malita 4 mpaka 8 a madzi omveka bwino, osungunula tsiku lililonse pamene akukumana ndi nseru ya hypercalcemic ndi kusanza komwe kumalepheretsa kumwa madzi okwanira kuti apitirize, kuwasiya 4 mpaka 6 malita akusowa madzi.

Chifukwa chiyani ndizowopsa kuti madokotala apereke IV furosemide (Lasix) nthawi yomweyo kuti atulutse calcium yochuluka?¶

Zaka makumi angapo zapitazo, mabuku azachipatala adaphunzitsa madokotala kupereka saline wamba komanso mlingo waukulu wa IV furosemide nthawi yomweyo kukakamiza impso kutulutsa calcium. Kafukufuku wazachipatala pambuyo pake adatsimikizira kuti kupereka loop diuretic ngati furosemide isanakwane 4-to-6-lita ya kuperewera kwa madzi m'thupi kwa wodwala kudzazidwanso ndi saline wamba ndikowopsa: kumawonjezera kuchepa kwa madzi m'thupi, kutsitsa magazi a impso (GFR), ndikukakamiza proximal tubule ya impso kuti ibwezenso sodium ndi calcium yambiri m'magazi, kupangitsa hypercalcemia kukhala yoyipa. Masiku ano, furosemide imabisidwa mpaka voliyumu ya intravascular itabwezeretsedwa bwino ndi malita a 0,9% ya saline wamba, ndipo imagwiritsidwa ntchito pokhapokha ngati wodwala achulukirachulukira.

Chifukwa chiyani madokotala amayenera kuwerengera "Albumin-Corrected Calcium" mwa odwala khansa?¶

Pafupifupi 40 mpaka 45 peresenti ya calcium yonse yomwe ikuyandama m'magazi anu imakhala ndi mapuloteni onyamula, makamaka albumin, pamene 50 peresenti yotsalayo ndi yaulere, yogwira ntchito "calcium ionized." Kashiamu ya ionized yaulere yokha imakhudza ubongo, mtima, ndi impso zanu. Odwala ambiri omwe ali ndi khansa kapena matenda aakulu amakhala ndi milingo yochepa kwambiri ya albumin m'magazi (hypoalbuminemia) chifukwa cha kusadya bwino kapena kutupa. Pamene albumin ili yotsika, kuyezetsa kwa labotale ya "kashiamu yonse" kumawonekera monyenga kapena kukwezeka pang'ono ngakhale kashiamu yowopsa ya ionized yaulere ili pamwamba kwambiri. Kuonjezera 0.8 mg/dL ku calcium yonse pa 1.0 g/dL iliyonse yomwe albumin ya seramu imagwera pansi pa 4.0 g/dL (kapena kuyeza kashiamu ya ionized mwachindunji) kumasonyeza kuopsa kwa vutoli.

Chifukwa chiyani madotolo amapatsa Subcutaneous Calcitonin NDI Intravenous Zoledronic Acid nthawi imodzi?¶

Intravenous Zoledronic Acid (a bisphosphonate yamphamvu) ndi Subcutaneous Denosumab ndi mankhwala amphamvu kwambiri oletsa kusweka kwa mafupa ndi kusunga kashiamu ya magazi kwa 3 mpaka masabata a 4, koma amatenga maola 48 mpaka 96 (masiku 2 mpaka 4) kuti ayambe kugwira ntchito. Mosiyana ndi zimenezi, Subcutaneous Salmon Calcitonin imayamba kutsitsa kashiamu m'magazi mkati mwa maola 4 mpaka 6 okha, koma imasiya kugwira ntchito pambuyo pa maola 48 chifukwa maselo a mafupa amabisala mwamsanga ma calcitonin receptors (tachyphylaxis). Kupereka mankhwala onse pamodzi pa Hour 0 kumagwiritsa ntchito Calcitonin yofulumira ngati mlatho wopulumutsa moyo wa maola 48 mpaka Zoledronic Acid kapena Denosumab ya nthawi yayitali ikuyamba pa Tsiku 3.

Kodi kuyezetsa magazi kwa Parathyroid Hormone (PTH) kosavuta kumauza bwanji madokotala ngati calcium yochuluka imayamba chifukwa cha khansa kapena chotupa cha parathyroid?¶

Mu Primary Hyperparathyroidism, imodzi mwa tinthu tating'onoting'ono tating'ono ta parathyroid pakhosi idapanga chotupa choyipa (adenoma) kapena hyperplasia yomwe imadzitulutsa yokha ya Parathyroid Hormone (PTH), kotero mayeso a labu amawonetsa kuti calcium yambiri m'magazi NDI PTH yapamwamba (kapena yosayenera) yokhazikika. Mu Hypercalcemia of Malignancy, khansara ikukweza kashiamu yamagazi mwina potulutsa timadzi tating'ono tomwe timatchedwa PTHrP (yomwe simalembetsa pa muyezo wa PTH lab assay) kapena kusungunula mwachindunji fupa, ndi tiziwalo timene timatulutsa timadzi tambiri tomwe timakhala m'khosi timakhala ndi calcium yokwera kwambiri ndikutseka kupanga kwawo kowona kwa PTH kwathunthu (kutsitsidwa pansipa 1g0m2L)

Kodi "Mafupa, Miyala, Kubuula kwa M'mimba, ndi Kusokoneza Maganizo" amatanthauza chiyani?¶

Mawu akale achipatala akufotokoza mwachidule machitidwe anayi a ziwalo zomwe zimakhudzidwa ndi hypercalcemia: "Mafupa" amatanthauza kupweteka kwakuya kapena kuthyoka kwa calcium kuchokera ku mafupa (osteitis fibrosa cystica kapena osteolytic metastases); "Miyala" amatanthauza kashiamu impso miyala ndi nephrogenic shuga insipidus kuchepa madzi m'thupi; "Kubuula m'mimba" kumatanthauza kudzimbidwa kwakukulu, nseru, kusanza, zilonda zam'mimba, komanso kapamba, hypercalcemic pancreatitis; ndi "Psychiatric Overtones" (kapena "Moans") amatanthauza kuvutika maganizo, kutopa kwambiri, kutaya kukumbukira, kusokonezeka, kuona zidziwitso, ndi chikomokere chifukwa calcium yochuluka imachepetsa kufalikira kwa mitsempha mu ubongo.
