Kana kukura zvakanyanya mumwana kunofambidzana nekuneta nokukurumidza, kukura kwepabonde kusina kunaka, zvirwere zvinowanzoitika, saka vabereki vanofanira kutsvaga rubatsiro rwakakodzera. Kana kusavapo kwezviratidzo zvakadaro, mumatambudziko mazhinji, hapana chikonzero chokufunganya nezvekukura nokukurumidza kwevana.
Kuwedzerwa kwebumbiro remitemo kwekura kwevana
Nhasi, vana vanowanzova nekugadziriswa kwebumbiro rekukura, kunze kwevanhu vane mazita evanhu vakakwirira. Muvana vakadaro nguva yeparertal inotanga kusvika, kukura nekutsvaga kwemapfupa kunowedzera. Vanhu vakakwirira mumitemo yepamutemo vakagadzikana zvakaenzana, havatambudziki nekuwedzera kudzvinyirira kusagadzikana.
Kukurumidza kukura kungaita kuti uwedzere kuwedzera muzera rekutanga, asi izvi ndezvenguva pfupi. Muchiitiko ichi, vana vanokura kure, asi kwete magamba.
Gigantism yevana
Kana mwana ane kukura kwehomoni uye nzvimbo yakazaruka munzvimbo yakawanda, ipapo gigantism inokura, uye vanhu vakuru vanokura acromegaly, zvisinei, uye ne gigantism, zviratidzo zveacromgaly zvinokwanisika, izvo mushure mokuvharwa kwe epiphyses zvinotora chimiro chakawedzerwa.
Kuwedzerwa kwekuwedzerwa kwekukura kwehomoni kunowanzokonzera kukura kwakanyanya kwemucheche, kunyanya mumitambo inokurudzira basa re hypothalamic-pituitary chikamu (kutumirwa encephalitis, hydrocephalus). Gigantism munyaya iyi inokura pasinei nezera, asi kazhinji kacho kukurumidza kukura kunowanikwa kune vana vari muchikoro chesekondari kana kuchikoro. Vana vakadaro vari nyore kuneta, kupikisa kwavo kune zvirwere kunoderedzwa, mutsara hauna kunyatsogadzirwa, nekunyatsoongorora iwe unogona kuona maitiro e acromegaloid, uye kusanganisa kwechiratidzo kunoonekwa.
Pashoma piritary pituitary gigantism. Chikonzero chekufambisa kwepituitary gigantism kazhinji kacho kusinganzwisisiki adenoma, kazhinji kacho nemukomana we hypothalamus.
Mune zvimwe zviitiko, acromegaly uye gigantism inotanga se hypothalamic disorders inotungamirira ku hyperplasia uye hypertrophy, iyo inogona kukonzera kukura-kufanana nekukura kwemasero ema somatotropic. Mune zvimwe zviitiko mu pubertal nguva inova pachena kuti mwana akawedzera kukura, asi dzimwe nguva inogona kuonekwa pazera remakore mashanu. Somugumisiro, kukura kunogona kusvika 250 kana kupfuura masentimita.
Kakawanda kazhinji kusanzwisisika kwekukura kunosvika nevana vane hutano hwekuita zvepabonde vasati vasvika, asi havasi kuva giants, nekuda kwekuvhara kwokutanga kwezvikwata zvekukura (mushure mekuvhara, kukura kumira).
Vasingazivikanwi vakareba varwere vane hypogonadism, thyrotoxicosis, pamwe chete nevarwere vane arachnodactyly (Marfan syndrome) vane zvirwere zvezvirwere zvezvirwere izvi, mune vakadai vakadaro huwandu hwekuwedzera kwehomoni inowanzoitika.
Chikonzero chekufambiswa kweClinifelter's syndrome chromosomal kuberration nekuvapo kweimwe X chromosome. Mudiki vakomana vane makumbo marefu asingaverengeki uye maoko muhucheche, muviri usina kusimba, uye gare gare unowedzera kuneta. Iyo syndrome yaClainfelter ine chimwe chinhu chakasiyana-hypoplasia yepenis uye testicles. Chikamu chepabonde chimiro hachina kugutsikana, pane dzimwe nguva gynecomastia inoonekwa, mvere dziri kuparadzirwa kuburikidza nemufananidzo wechikadzi.
Mune varwere vakadai, pane chigadziko mumagariro ekuvandudza pfungwa, izvi zvinotsanangurwa nemamwe ma X chromosome.
Sotos syndrome (cerebral gigantism), kusiyana nepituitary gigantism, inoitika kakawanda, uye inofambidzana nekukura nokukurumidza, asi mu serum yezinga re somatotropin inoramba iri yakakwana, uye data inoratidza kuti chinokonzera chirwere chinetso cheupfungwa.
Kwemakore 4-5 mwana anokura nokukurumidza, uye ipapo mwana anowedzera zvakare. Nguva yekuparidzira inotanga zvishomanana pfupi kana mumagariro evamwe. Mune varwere vakadaro, pane maziso makuru uye mabhesi nehupamhi hwakawanda hwehutsetse mafuta. Pano pane chirwere chepfungwa mukukudziridza. Musoro we dolichocephalic fomu yakakura, tsvina yakadzika inofamba mberi, kufamba kunofadza, maziso ari akaparadzana, murwere ane tsvina, kuwirirana kwekutama kunovhiringidzika.
