Ukuhlolwa Kwemitholampilo Kwezinkinga Ze-Endocrine
Izinkinga ze-endocrine ziyiqembu lezifo ezivela ekungalingani ekukhiqizweni, ekukhiqizweni, ekuthuthweni, noma ekusebenzeni kwama-hormone ezicutshini eziqondiwe. Ngenxa yokuthi ama-hormone alawula imetabolism, ukukhula, ukuzala, izimpendulo zokucindezeleka, kanye nokulinganisela koketshezi kanye ne-electrolyte, ukuphazamiseka kwesistimu ye-endocrine kuvame ukubangela izimpawu eziningi, ngezinye izikhathi ezingaqondile. Ngakho-ke, ukuhlolwa kwezokwelapha kwezinkinga ze-endocrine kudinga indlela ehlelekile ehlanganisa ukuthatha umlando, ukuhlolwa ngokomzimba, ukuhlolwa kwelebhu okufanele, kanye nokuthwebula izithombe lapho kudingeka. Lesi sihloko sixoxa ngezinyathelo ezibalulekile ekuhlolweni kwezokwelapha kwezinkinga ze-endocrine, kufaka phakathi izimiso zokuchazwa kwemiphumela yokuhlolwa kanye nezingibe ezivamile zokuxilonga.
1. Izimiso ezijwayelekile zokuhlolwa kwe-endocrine
Esimisweni se-endocrine, izikhalazo zeziguli zivame ukubonakala “zivamile,” njengokukhathala, ukushintsha kwesisindo, ukuphazamiseka kokulala, ukushintshashintsha kwemizwa, noma ukungahambi kahle kokuya esikhathini. Inselele yodokotela ukuhlukanisa ukuthi lezi zikhalazo ziwukuhlukahluka komzimba, umphumela wesifo esingeyona i-endocrine, umphumela wemithi, noma ukuphazamiseka kwamahomoni kwangempela. Izimiso ezimbili ezibalulekile ekuhlolweni yilezi: (1) ukuhlola ukuthi lesi sifo sikhipha i-hypersecretory (ukweqisa kwamahomoni) noma sikhipha i-hyposetory (ukuntuleka kwamahomoni), kanye (2) nokunquma ukuthi lesi sifo siyinhloko (sivela ezindlala ze-endocrine) noma sesibili/esithathu (sivela ku-pituitary noma ku-hypothalamus).
Ngaphezu kwalokho, ama-hormone angaguquguquka ngokwezigqi ze-circadian (isb., i-cortisol), athonywe isimo sokudla (i-insulin, i-glucose), ukucindezeleka okukhulu, ukukhulelwa, ukugula okukhulu, kanye nokusebenzisana kwezidakamizwa. Isikhathi sokuthola isampula kanye nomongo wezokwelapha kunquma ukunemba kokuchazwa.
2. I-anamnesis eqondisiwe: ukumba izinkomba ezibalulekile
Umlando uyisisekelo sokuhlolwa kwe-endocrine. Ezinye izingxenye ezibalulekile zifaka:
1) Isikhalazo esiyinhloko kanye nokulandelana kwezikhathi
Ingabe izimpawu zivele ngokuzumayo noma kancane kancane? Izinkinga ze-thyroid zingakhula kancane, kanti ukungasebenzi kahle kwe-adrenal kunganda ngokushesha, ikakhulukazi ngaphansi kokucindezeleka kokutheleleka.
2) Izimpawu zesistimu
Ukushintsha kwesisindo, ukungabekezelelani nokushisa/ukubanda, izinguquko ekufiseni ukudla, i-polyuria/polydipsia, ukushaya kwenhliziyo, ukuthuthumela, ukuqunjelwa/uhudo, ubuthakathaka bemisipha, ukushintsha kwesikhumba nezinwele.
3) Umlando wokuzala
Kwabesifazane: ukungahlali kahle esikhathini, ukungabi nabantwana, i-galactorrhea, izimpawu ze-hyperandrogenism (induna enkulu, i-hirsutism). Kwabesilisa: ukwehla kwesifiso sobulili, ukungasebenzi kahle kwe-erectile, ukungabi nabantwana, i-gynecomastia.
4) Umlando womndeni
Izifo ezizenzakalelayo (i-Hashimoto's thyroiditis, i-Graves'), isifo sikashukela, noma izifo zofuzo ezifana ne-MEN (Multiple Endocrine Neoplasia) zingase zinikeze izinkomba zembangela.
5) Imithi kanye nokuchayeka
Ama-glucocorticoids (angacindezela i-axis ye-HPA), ama-amiodarone (izinkinga ze-thyroid), i-lithium (i-hypothyroidism), ama-antipsychotics athile (i-hyperprolactinemia), imithamo ephezulu ye-biotin (iphazamisa ukuhlolwa kwe-immunochemical), kanye nezithasiselo zama-hormone noma ama-anabolic steroids.
6) Izimo ezikhethekile
Ukukhulelwa, ukuncelisa, ukugula okukhulu, ukungondleki kahle, noma izifo zengqondo kungalingisa noma kushintshe isithombe se-endocrine.
3. Ukuhlolwa komzimba: hlola izimpawu zamahomoni
Ukuhlolwa ngokomzimba ngokucophelela kuvame ukunikeza izinkomba eziqinile zokuxilonga:
– Izimpawu zesifo se-thyroid: i-thyroid gland ekhuphukile, ukuthuthumela okuncane, i-tachycardia, i-hyperactive reflexes (i-hyperthyroidism), isikhumba esomile kanye ne-bradycardia (i-hypothyroidism), kanye ne-Graves' orbitopathy.
– Izimpawu ze-Cushing's syndrome: ukukhuluphala okuphakathi, ubuso obuyindilinga, ama-striae abanzi onsomi, ukuphuka kalula, ubuthakathaka bemisipha eseduze, umfutho wegazi ophakeme.
– Izimpawu zokungapheleli kwe-adrenal: i-hyperpigmentation (ekungeneni kahle okuyinhloko), i-orthostatic hypotension, ukuphelelwa ngamanzi emzimbeni.
– Izimpawu ze-acromegaly: ukukhulisa izandla nezinyawo, izinguquko zobuso, ukubikezela ukuzalwa kwengane, ukujuluka ngokweqile.
– Izimpawu zezinkinga ze-parathyroid/calcium: i-tetany, ukuqaqamba kwemisipha, uphawu lwe-Chvostek/Trousseau (hypocalcemia), noma amatshe ezinso kanye nobuhlungu bamathambo (hypercalcemia).
– Ukuhlolwa kokuthomba kanye nezici zobulili zesibili: kubalulekile ezifweni ze-gonadal kanye ne-pituitary.
4. Ukuhlolwa kwelabhorethri: ukukhetha izivivinyo ezinengqondo
Ku-endocrinology, akuzona zonke izivivinyo "eziyindlela eyodwa." Izimo eziningi zidinga izivivinyo zokuhlolwa, kulandelwe ukuhlolwa okuqinisekisayo noma okunamandla.
a) I-hormone ye-thyroid
– I-TSH kanye ne-T4 yamahhala yizona nhlanganisela eziyinhloko. I-TSH iyazwela kwi-hypothyroidism eyinhloko, kodwa ezinkingeni ze-pituitary (i-hypothyroidism ephakathi), i-TSH ingaba ejwayelekile noma ibe phansi, okwenza i-T4 yamahhala ibe yinto ebalulekile.
– Ama-antibodies (anti-TPO, TRAb) asiza ekunqumeni imbangela yokuzivikela komzimba.
b) Isifo sikashukela kanye nokusetshenziswa kwe-glucose emzimbeni
– I-GDP (ukuzila ukudla kweglucose egazini), i-HbA1c, kanye ne-OGTT kusetshenziswa ngokuya ngomongo.
– Uma kwenzeka i-hypoglycemia ephindaphindayo, ukuhlolwa kwe-“Whipple's triad” kanye nokuhlolwa kwe-insulin, i-C-peptide, kanye ne-sulfonylureas kungahlola ukuthi kungenzeka yini ukuthi i-insulinoma noma ukusetshenziswa kwezidakamizwa.
c) I-adrenal axis (i-cortisol)
– Kubantu abasolwa ngokuba yi-Cushing's, ukuhlolwa kungafaka ukuhlolwa kokucindezela i-dexamethasone ngomthamo ophansi, i-cortisol yamathe yasebusuku, noma i-cortisol yomchamo emahoreni angama-24.
– Uma kwenzeka ukungasebenzi kahle kwe-adrenal, i-cortisol yasekuseni kanye ne-ACTH, bese kwenziwa isivivinyo sokukhuthazwa kwe-ACTH (i-Synacthen) uma kudingeka.
d) I-Prolactin kanye ne-gonadotropin
– I-Hyperprolactinemia kufanele icatshangelwe ngenxa yokukhulelwa, i-hypothyroidism, imithi, kanye ne-prolactinoma. Ukuhlolwa kwe-TSH kubalulekile njengembangela yesibili.
– I-LH/FSH kanye nama-hormone ocansi (i-estradiol/testosterone) kusiza ukuhlukanisa i-hypogonadism eyinhloko nesesibili.
e) I-Calcium, i-PTH, kanye ne-Vitamin D
– I-Hypercalcemia idinga ukuhlolwa kwe-PTH (iphezulu ku-hyperparathyroidism eyinhloko; iphansi ku-moldy noma ezinye izimbangela).
– I-Hypocalcemia idinga ukulungiswa kwamazinga e-albumin, kanye nokucatshangelwa kwe-magnesium ne-vitamin D.
5. Ukuhlolwa okunamandla: kunini lapho kudingeka khona?
Ukuhlolwa okunamandla kusetshenziswa lapho izilinganiso eziyisisekelo zinganele ngenxa yama-hormone ashintshashintshayo noma lapho kudingeka ukuhlola izimpendulo. Izibonelo:
– Ukuhlolwa kokucindezela i-Dexamethasone kwe-Cushing's.
– Ukuhlolwa kokukhuthazwa kwe-ACTH kokungasebenzi kahle kwe-adrenal.
– I-OGTT ene-GH ukuhlola i-acromegaly (i-GH kufanele icindezelwe ngemva kwe-glucose).
Ukuhlolwa okunamandla kufanele kwenziwe kucatshangelwa ukuphepha, iziphazamiso, kanye nesimo sesiguli, njengoba kungabangela izinguquko ezinkulu zomzimba.
6. Izinqubo zokuthatha izithombe nokusekela
Uma i-biochemistry iholela ekuxilongweni, ukuthwebula izithombe kusiza ekutholeni indawo kanye nembangela:
– I-ultrasound ye-thyroid yamaqhubu noma i-goiter; i-scintigraphy ingahlola amaqhubu “ashisayo” noma “abandayo”.
– I-MRI ye-pituitary ye-adenoma okusolwayo (i-prolactinoma, i-acromegaly, i-Cushing's ebangelwa yi-ACTH).
– I-Adrenal CT/MRI yezimila noma i-hyperplasia.
– I-DXA (i-bone densitometry) ezinkingeni ezithinta amathambo, njenge-hyperthyroidism eseyinde isikhathi eside, i-hyperparathyroidism, noma i-hypogonadism.
Kubalulekile ukukhumbula ukuthi ukuthatha izithombe ngaphandle kwesisekelo se-biochemical ngezinye izikhathi kungaholela ekutholakaleni okungahleliwe okudidayo. Ngakho-ke, ukulandelana okuhle ngokuvamile ukuqala ngokuhlolwa kwezokwelapha kanye ne-biochemical, kulandelwe ukuthatha izithombe okuqondiwe.
7. Izingibe ezivamile zokuxilonga
Amanye amaphutha avamile ekuhlolweni kwe-endocrine afaka:
– Unganaki ithonya lemithi kanye nezithasiselo, isibonelo i-biotin engabangela ukuthi imiphumela ye-TSH/T4 engenayo ibonakale “ingamanga”.
– Ukuhumusha imiphumela ngaphandle kokucabangela izilinganiso zansuku zonke, ikakhulukazi i-cortisol.
– Ayihlukanisi phakathi kwezifo eziyinhloko neziphakathi, njengokuthi i-central hypothyroidism ayitholakali uma ubheka i-TSH kuphela.
– Ungaphindi ukuhlolwa uma imiphumela ingasenamkhawulo, ngoba ukuhlukahluka kwezinto eziphilayo kanye nokuhlaziya kungathinta imiphumela.
8. Isiphetho
Ukuhlolwa kwezifo ze-endocrine emtholampilo kudinga indlela ehlelekile: ukuqala ngomlando ophelele, ukuhlolwa ngokomzimba okuphelele, ukuhlolwa kwelabhorethri okufanele (kufaka phakathi ukuhlolwa okuguquguqukayo uma kudingeka), kanye nokuthwebula izithombe okusekelwe ezinkomba ze-biochemical kanye nezokwelapha. Ngokuqonda izimiso zempendulo yama-hormone, ukuhlukahluka kokuphila, kanye nezici ezididayo njengemithi kanye nezimo ezibucayi, odokotela bangathuthukisa ukunemba kokuxilonga futhi bagweme ukungenelela okungadingekile. Ekugcineni, ukuhlolwa okuhle kudlula nje ekutholeni "izinombolo zama-hormone" kodwa kunalokho kubeka leyo miphumela kumongo wesiguli sonke ukuze kunqunywe uhlelo lokuxilongwa nokwelashwa olufanele kakhulu.
