Kotatsu-induced erythema ab igne

Exposome factors that lead to stressed skin can be defined as any disturbance to homeostasis from environmental (meteorological factors, solar radiation, pollution or tobacco smoke) and/or internal exposure (unhealthy diet, hormonal variations, lack of sleep, psychosocial stress). The clinical and biological impact of chronic exposome effects on skin functions has been extensively reviewed, whereas there is a paucity of information on the impact of short‐term acute exposure. Acute stress, which would typically last minutes to hours (and generally no more than a week), provokes a transient but robust neuroendocrine‐immune and tissue remodelling response in the skin and can alter the skin barrier. Firstly, we provide an overview of the biological effects of various acute stressors on six key skin functions, namely the skin physical barrier, pigmentation, defences (antioxidant, immune cell‐mediated, microbial and microbiome maintenance), structure (extracellular matrix and appendages), neuroendocrine and thermoregulation functions. Secondly, we describe the biological and clinical effects on adult skin from individual exposome factors that elicit an acute stress response and their consequences in skin health maintenance. Clinical manifestations of acutely stressed skin may include dry skin that might accentuate fine lines, oily skin, sensitive skin, pruritus, erythema, pale skin, sweating, oedema and flares of inflammatory skin conditions such as acne, rosacea, atopic dermatitis, pigmentation disorders and skin superinfection such as viral reactivation. Acute stresses can also induce scalp sensitivity, telogen effluvium and worsen alopecia.

“…[2][3][4][5] The prognosis of the disease is good if an early measure is taken for heat exposure. 6,7 To our best knowledge, although there are a large number of case reports [8][9][10][11] on EAI, there are no retrospective or prospective studies involving a large number of patients for clinical features and etiologic reasons. The aim of this study was to investigate the demographic and clinical features, etiology of patients with EAI who admitted to our clinics.…”

Objective The aim of this study was to investigate the demographic and clinical features, etiology of patients with erythema ab igne (EAI) who presented to our clinics. Materials and Methods The present study was conducted on 71 patients who were admitted to our dermatology clinics between April 2018 and June 2019 and were diagnosed with EAI by clinical or histopathological examination. Age, gender, localization of lesions, and etiologic causes of lesions were recorded. Results Of the 71 patients, 48 (67.6%) were women and 23 (32.4%) were men. The mean age of the patients was 28.6 ± 10.4 years. Most of the lesions were localized (60.6%, n = 43) on the anterior aspect of both legs. Among the etiological reasons, 53 (74.6%) patients had exposure to heater, 14 (19.7%) patients had exposure to stove, 2 (2.8%) patients had laptop use, 1 (1.4%) patient had tandoor contact, and 1 (1.4%) patient had exposure to hot water bag. One patient was diagnosed with bullous EAI. Conclusion In conclusion, EAI was also more common in females and lower extremities, which is in accordance with the literature. However, the mean age of occurrence in our study is younger when compared with that in the literature. One case of EAI due to the use of tandoor in our study has not been reported previously. It should be kept in mind that bullous EAI may develop in patients with diabetes mellitus.

“…Infrared (IR) is nonionizing radiation that accounts for half of the solar spectrum and is perceived as heat [ 38 ]. Its ability to induce erythema and skin pigmentation is evidenced in erythema ab igne [ 39 ]. IR exposure has been indicated as a cause of matrix metalloproteinase 1 (MMP1) activation, vasodilatation, proinflammatory cytokine release, direct cytotoxicity, and increased oxidative stress and DNA damage, leading to photoaging.…”

Melasma is a multifactorial dyschromia that results from exposure to external factors (such as solar radiation) and hormonal factors (such as sex hormones and pregnancy), as well as skin inflammation (such as contact dermatitis and esthetic procedures), in genetically predisposed individuals. Beyond hyperfunctional melanocytes, skin with melasma exhibits a series of structural and functional alterations in the epidermis, basement membrane, and upper dermis that interact to elicit and sustain a focal hypermelanogenic phenotype. Evolution in the knowledge of the genetic basis of melasma and the cutaneous response to solar radiation, as well as the roles of endocrine factors, antioxidant system, endothelium proliferation, fibroblast senescence, mast cell degranulation, autophagy deficits of the melanocyte, and the paracrine regulation of melanogenesis, will lead to the development of new treatments and preventive strategies. This review presents current knowledge on these aspects of the pathogenesis of melasma and discusses the effects of specific treatments and future research on these issues.
