“…NIR induces photoaging similar to that observed in solar elastosis, and enhances UV-induced dermal damage [25]. Long-term exposure of NIR from various heat sources, such as fires and stoves, results in erythema ab igne [26], and results in histopathological changes similar to those seen in solar-damaged skin [27]. The occurrence of telangiectasia appeared to increase with age, increased sunbathing, and poor pigmentation ability [28].…”

Protection from Near-Infrared to Prevent Skin Damage

Over half of the solar energy consists of near-infrared, and in addition to natural near-infrared, humans are increasingly exposed to artificial near-infrared from electrical appliances. Thus, we are exposed to tremendous amounts of near-infrared. Despite the wide prevalence of a variety of ultraviolet blocking materials, the necessity to protect against near-infrared has not been well recognized. To clarify the necessity to protect against near-infrared, we assessed cell viability of human fibroblast cells after water-filtered broad-spectrum near-infrared (1100 -1800 nm together with a water-filter that excludes wavelengths 1400 -1500 nm) treatment using 2 sets of transparent polycarbonate plates, one to block ultraviolet and the other to block both ultraviolet and near-infrared. The cell viability was significantly decreased after 10 rounds of near-infrared irradiation at 20 J⁄cm 2 in near-infrared treated cells without a protective polycarbonate plate and near-infrared treated cells using the polycarbonate plate to block only ultraviolet. Assuming that the cell viability of the non-irradiated control to be 100, the cell viability of the near-infrared treated cells without any protection was 0.2. The cell viability of the near-infrared treated cells with the polycarbonate plate to block only ultraviolet was 0.3, whereas both ultraviolet and nearinfrared protected cells retained a viability of 85.1. The results of this study indicate that protection from not only ultraviolet but also near-infrared should be considered to prevent skin damage.

“…The skin temperatures achieved are probably within the region of 43°to 47°C (Hardy et al 1965) which is insufficient to cause unbearable pain or burning. The pathology of the skin changes and proposed mechanisms are discussed elsewhere (Finlayson et al 1966, Johnson & Butterworth 1971, Kligerman & Kligerman 1984, Shahrad & Marks 1977, Waldorf et al 1971, as is the documentation of pre-malignant and malignant skin changes within areas of established EAI (Arrington & Lockman 1979, Cross 1967, Grant-Peterkin 1955. All 5 patients reported here had been applying hot-water bottles to the painful area tor at least one month, and a precise history of two and a half months was obtained in one case.…”

Summary: Five cancer patients were observed to have the skin change erythema ab igne (EAI) associated with painful underlying lesions, for which they had been applying local heating with hot-water bottles. In 4 cases the pain was produced by metastases and in one by the primary tumour. The EAI may be seen directly over the lesion or in an area of pain referral. In cancer patients it may be a helpful localizing sign, and in all patients (apart from the anterior lower legs of old people) it is very suggestive of a serious underlying cause.

“…5 There is also an accumulation of elastic tissue in the superior dermis. 5,6 ASome cases exhibit hyperkeratosis and epidermal dysplasia, similar to actinic keratosis. 3,4,6 The lesion characteristic of EAI associated to a history of excessive exposure to heat in the area of onset facilitates clinical diagnosis of this disease.…”

“…[1][2][3] It is characterized by reticulate erythema, hyperpigmentation, scaling, epidermal atrophies and telangiectasis, present in areas of prolonged exposure to thermal radiation. [4][5][6] It is usually asymptomatic, but patients can refer to ardor and pruritus. 6 The lesion is acquired by repeated and prolonged 7 exposure to infrared radiation at temperatures up to 45°C.…”

Abstract:The cutaneous lesion of erythema ab igne is characterized by a reticulate erythema, hyperpigmentation, fine scaling, epidermal atrophy and telangiectasis. Currently the lumbar region is the most affected, due to the use of hot water bottles to relieve chronic pains, and by constant exposure to deep heat in physiotherapy sessions. The authors call attention to a dermatosis that is not often diagnosed, and that may be more prevalent, because of the high frequency with which such physiotherapeutic treatments are performed. Keywords: Erythema; Physical therapy (specialty); Thermal radiation. At present, erythema ab igne (EAI) or erythema caloricum is either rare or infrequently reported. Resumo
