Erythema ab igne, also known as hot water bottle rash, is a skin condition caused by long-term exposure to heat (infrared radiation). Prolonged thermal radiation exposure to the skin can lead to the development of reticulated erythema, hyperpigmentation, scaling and telangiectasias in the affected area. Some people may complain of mild itchiness and a burning sensation, but often, unless a change in pigmentation is seen, it can go unnoticed.
☆ AI Dermatology — Free Service Emiphumeleni ka-2022 ye-Stiftung Warentest evela eJalimane, ukwaneliseka kwabathengi nge-ModelDerm bekungaphansi kancane kunokuxhumana okukhokhelwayo kwe-telemedicine.
I-Erythema ab igne ukuqubuka okubangelwa ukuchayeka kaningi ekushiseni noma emisebeni ye-infrared. Kuvame ukuvela emisebenzini noma ekusebenziseni amaphedi okushisa. Ukwelashwa okuyinhloko ukukhipha umthombo wokushisa. Ukuphuma kungase kuphele ngokuhamba kwesikhathi, kodwa kungashiya i‑hyperpigmentation unomphela noma izibazi. Ukwelashwa okufana ne‑tretinoin noma i‑hydroquinone kungasiza ekunciphiseni i‑hyperpigmentation eqhubekayo. Erythema ab igne is a rash characterized by a reticulated pattern of erythema and hyperpigmentation. It is caused by repeated exposure to direct heat or infrared radiation, often from occupational exposure or the use of heating pads. The primary treatment of this disease entity is the removal of the offending heat source. The resulting abnormal pigmentation of affected areas may resolve over months to years; however, permanent hyperpigmentation or scarring may persist. Treatments for hyperpigmentation, such as topical tretinoin or hydroquinone, can be useful in treating persistent hyperpigmentation.
Izinhlobo ezahlukene zemithombo yokushisa ezingabangela lesi simo zifaka phakathi:
- Ukusebenzisa ngokuphindaphindiwe amabhodlela amanzi ashisayo, izingubo zokulala ezishisayo noma ama‑heat pads ukwelapha ubuhlungu obungapheli.
- Ukuchayeka kaningi ezihlalweni zemoto ezishisayo, izifudumezi zesikhala, noma iziko lokushisa. Ukuchayeka kaningi noma isikhathi eside kumashini okushisa kuyimbangela evamile kubantu asebekhulile.
- Izingozi zomsebenzi zabakhandi besiliva nobucwebe (ubuso obuchayeke ekushiseni), ababhaki nabapheki (izingalo, ubuso).
- Ukusebenzisa ikhompuyutha ephathwayo ethangeni (i‑erythema ab igne eyenziwe ngekhompyutha).
