Pityriasis roseahttps://en.wikipedia.org/wiki/Pityriasis_rosea
Is cineál gríos craicinn é Pityriasis rosea . Tosaíonn an lot le limistéar amháin dearg agus beagán scaly. Ina dhiaidh sin, laethanta go seachtainí ina dhiaidh sin, tá gríos de go leor loit chruinn nó ubhchruthach den chineál céanna ach níos lú, go príomha ar an stoc agus ar na géaga uachtaracha. De ghnáth maireann sé níos lú ná trí mhí agus imíonn sé gan chóireáil. Uaireanta d’fhéadfadh malaise nó fiabhras tarlú roimh thús na gríosa nó na n-itchiness, ach is minic nach mbíonn mórán comharthaí eile ann.

Cé nach bhfuil an chúis go hiomlán soiléir, creidtear go bhfuil baint aige le herpesvirus daonna 6 nó herpesvirus daonna 7. Ní cosúil go bhfuil sé tógálach. D’fhéadfadh gríos den chineál céanna a bheith mar thoradh ar chógais áirithe. Tá diagnóis bunaithe ar na hairíonna agus de ghnáth ní gá bithóipse.

Mar ghalar coitianta, déantar difear do thart ar 1.3% de dhaoine ag am éigin. Tarlaíonn sé go minic i ndaoine idir 10 agus 35 bliain d’aois.

Diagnóis agus Cóireáil
Má leanann sé ar feadh níos mó ná 1 mhí, d'fhéadfadh go mbeadh gá le hobair mhionsonraithe chun é a dhifreáil ó ghalair eile (parapsoriasis, sifilis).

  • Pityriasis rosea ar chúl ― Macúil agus paistí asymptomatic, murab ionann agus brúchtaí drugaí a chosnaíonn de ghnáth.
  • herald patch ― Paiste mór sceach a thosaíonn roimh an gcuid eile den lot agus a mheastar ar dtús gur ionfhabhtú fungal é.
  • Pityriasis rosea ar torso ― Tá an chuid is mó de na loit suite ar an torso mar go gcuireann solas na gréine feabhas ar an lot.
  • Má tá cos ar bolg ort, seans go mbeidh amhras ort faoi ghalar ailléirgeach mar nummular eczema.

  • Beag herald patch.

Is riocht sealadach craiceann é Pityriasis rosea atá marcáilte le paistí agus scálaí ardaithe. Tosaíonn sé de ghnáth le paiste amháin, ar a dtugtar an herald patch , agus níos mó paistí le feiceáil ina dhiaidh sin sna cúpla seachtain atá romhainn. Mar sin féin, ní bheidh an paiste tosaigh seo ag gach duine le pityriasis rosea. Is minic a chruthaíonn na paistí seo patrún sainiúil cosúil le crann Nollag ar an stoc agus ar na géaga uachtaracha.
Pityriasis rosea, also known as pityriasis circinata, roseola annulata, and herpes tonsurans maculosus is an acute self-limiting papulosquamous disorder. It is often characterized by an initial herald patch, followed by scaly oval patches within 2 weeks. However, the herald patch is not always present. The scaly oval patches typically distribute in a Christmas-tree pattern on the trunk and proximal extremities. This activity reviews the evaluation and treatment of pityriasis rosea and the importance of the interprofessional team in recognizing and managing patients with this condition.

Is gríos coitianta é Pityriasis rosea a thosaíonn de ghnáth le paiste amháin ar an stoc agus a leathnaíonn chun an stoc agus na géaga a chlúdach. Braitheann diagnóis ar scrúdú cliniciúil. Is cosúil go bhfuil an paiste tosaigh dearg le teorainn ardaithe agus lárionad báite. Is gnách go dtagann an gríos chun solais thart ar dhá sheachtain ina dhiaidh sin. D’fhéadfadh tuirse, masmas, tinneas cinn, pian sna hailt, nóid limfe ata, fiabhras, agus scornach tinn taobh leis an ngríos a bheith ag othair. I measc na gcoinníollacha comhchosúla tá sifilis, dheirmitíteas seborrheic, eachma, agus daoine eile. Tá sé mar aidhm ag cóireáil comharthaí a mhaolú le corticosteroidí nó frithhistamíní. Féadfaidh Acyclovir cabhrú i gcásanna áirithe. Féadfaidh cásanna tromchúiseacha leas a bhaint as fótaiteiripe UV. Uaireanta tá an galar le linn toirchis nasctha le breith anabaí.
Pityriasis rosea is a common rash that usually begins with a single patch on the trunk and spreads to cover the trunk and limbs. Diagnosis relies on clinical examination. The initial patch appears red with a raised border and sunken center. The rash typically emerges about two weeks later. Patients may experience fatigue, nausea, headaches, joint pain, swollen lymph nodes, fever, and sore throat alongside the rash. Similar conditions include syphilis, seborrheic dermatitis, eczema, and others. Treatment aims to alleviate symptoms with corticosteroids or antihistamines. Acyclovir may help in some cases. Severe instances may benefit from UV phototherapy. The disease during pregnancy sometimes has been linked to miscarriage.

In most cases, PR does not influence pregnancy or birth outcomes. Analysis of pooled data from our study and from previous studies revealed that the week of pregnancy at onset of PR was inversely associated with an unfavorable outcome (odds ratio [OR] = 0.937; 95 % CI 0.883 to 0.993). In addition, duration of PR (OR = 1.432; 95 % CI 1.129 to 1.827), additional extracutaneous symptoms (OR = 4.112; 95 % CI 1.580 to 10.23), and widespread rash distribution (OR 5.203, 95 % CI 1.702 to 14.89) were directly associated with unfavorable outcome.

Is riocht craiceann coitianta é Pityriasis rosea a théann i bhfeidhm go hiondúil ar dhéagóirí agus ar dhaoine fásta óga (aois 10-35) , beagán níos mó ná sin i mná. Tosaíonn sé go tobann, de ghnáth le paiste amháin ar a dtugtar Herald patch ar an stoc, agus ina dhiaidh sin gríos de spotaí beaga ubhchruthacha bándearga timpeallaithe ag fáinne liathghlas. Is minic a chruthaíonn na spotaí seo patrún cosúil le Christmas tree ar an stoc. Maireann an gríos ar feadh thart ar 6 go 8 seachtaine de ghnáth. Pityriasis rosea bíonn tionchar aige ar thart ar 0. 68% de na daoine a fheiceann dermatologist, ach is féidir é seo a athrú ó 0. 39% go 4. 8%.
Pityriasis rosea (PR) is a relatively common, self-limited papulo-squamous dermatosis of unknown origin, which mainly appears in adolescents and young adults (10-35 years), slightly more common in females. It has a sudden onset, and in its typical presentation, the eruption is preceeded by a solitary patch termed “herald patch”, mainly located on the trunk. Few days later, a secondary eruption appears, with little pink, oval macules, with a grayish peripheral scaling collarette around them. The secondary lesions adopt a characteristic distribution along the cleavage lines of the trunk, with a configuration of a “Christmas tree”. In most cases, the eruption lasts for 6 to 8 wk. Its incidence has been estimated to be 0.68% of dermatologic patients, varying from 0.39% to 4.8%.
