INTRODUCTION: The standard treatment for lichen sclerosus (LS) is symptomatic and is primarily based on the chronic use of corticosteroids, sometimes resulting in unsatisfactory effects. Therefore, other non-pharmacological methods are being sought, which are less aggravating for the patient. LS can be treated topically by using photodynamic therapy (PDT) based on 5-aminolevulinic acid (5-ALA). Unfortunately, therapy with the red light is often connected with severe local pain during the illumination...

Atopic dermatitis (AD) is a common, chronic skin inflammatory disorder characterized by perivascular infiltration of immunoglobulin E (IgE), T lymphocytes, and mast cells. The key factors responsible for the pathophysiology of this disease are immunological disorders and defects in epidermal barrier properties. Pruritus, intense itching, psychological stress, deprived physical and mental performance, and sleep disturbance are the hallmark features of this dermatological disorder. Preventive interventions such as educational programs, avoidance of allergens, and exclusive care toward the skin could play a partial role in suppressing the symptoms...

Skin aging is a continuous process that exhibits fine and deep wrinkles, thin and transparent skin, loss of underlying fat, dry skin and itch, following decreased collagen and elastin synthesis. Both extrinsic and intrinsic agents are considered in the pathogenesis on skin aging. Extrinsic factors such as sun exposure, windy and dry weather, nutrition, and lifestyle may induce premature aging, toxic-free radicals, and reactive oxygen species due to decreasing normal function of mitochondria which play the major intrinsic factors in premature skin aging...

Pruritus, a distressing symptom that affects burn patients, not only interferes with activities of daily living but also causes disturbed sleep, which has been associated with anxiety, depression, and other types of negative moods. Furthermore, the uncontrolled scratching that often accompanies pruritus causes tissue damage and may damage or destroy the skin graft. In this paper, the authors first describe the definition and mechanism of pruritus and next use itching-assessment tools to identify the triggering factors...

INTRODUCTION: Scabies is a contagious disease primarily related to poverty and overcrowding, it rapidly spreads from person to person specially in people with poor hygiene. We come across many patients from rural areas with scabies. In India the incidence ranges from 13% to 59% in rural and urban areas. Many people complain of sleep disturbances and affection of work and leisure activities due to itching. Very few studies are done in India about the affection of quality of life in such patients...

Chronic itch in inflammatory skin diseases, such as atopic dermatitis, markedly diminishes the quality of life of affected individuals. Comprehensive progress has been made in understanding itch signaling and associated mediators in the skin, dorsal root ganglia, spinal cord, and central nervous system, which may amplify or suppress atopic itch. Conventional therapies for atopic dermatitis are capable of reducing atopic itch; however, most patients are not satisfied with the antipruritic capacity of conventional treatments...

Paederus dermatitis is an acute irritant dermatitis resulting from contact with the hemolymph of Paederus beetles. This dermatitis mimics other infectious skin disorders, often resulting in diagnostic dilemmas. This study of 46 patients was conducted to increase awareness about Paederus dermatitis. Possible causes of a number of cases of Paederus dermatitis in Giresun, Turkey, were investigated using climate data and telephone interviews with the patients about risk factors. Insects caught by patients were identified at the species level...

The goals of this German guideline are the improvement of diagnosis and therapy of scabies, the implementation of a coordinated action in outbreaks of scabies, and the control of this infestation in large migration or refugee flows.Sarcoptes scabiei var. hominis is transmitted by direct skin-to-skin contact of sufficient duration. The infectivity of female mites when removed from patients does not exceed 48 hours at room temperature (21°C) and relative humidity of 40-80%. The risk of infection rises proportionally to the number of mites on the skin and is particularly high in crusted scabies...

Lichen planus (LP) is an inflammatory disease that affects the skin-mainly the extremities and the trunk-the mucous membranes, the genitalia, the nails and the scalp. The diagnosis of LP is usually established clinically based on the typical morphology and distribution of the lesions in conjunction with the associated itch. We report a patient with LP manifesting highly psoriasiform lesions, that could only be correctly assessed after the application of dermoscopy, which revealed LP-specific findings.

ETHNOPHARMACOLOGICAL RELEVANCE: Bletilla striata (Thunb.) Reichb. f. (Orchidaceae), also known as Hyacinth Orchid and Baiji (Simplified Chinese: ), not only has been widely used for the treatment of hematemesis, hemoptysis, and traumatic bleeding due to the efficacy of arresting bleeding with astringent action, but also has been applied topically to overcome ulcers, sores, swellings, and chapped skin due to the efficacy of dispersing swelling and promoting tissue regeneration. Additional medical applications include the treatment of tuberculosis, malignant ulcers, hemorrhoids, anthrax, eye diseases, and silicosis...

Atopic dermatitis (AD) displays different clinical symptoms, progress, and response to treatment during early infancy and after childhood. After the childhood period, itch appears first, followed by formation of well-circumscribed plaque or polymorphous dermatoses at the same site. When accompanied with dermatitis and dry skin, treatment of skin lesions should be prioritized. When itch appears first, disease history, such as causes and time of appearance of itch should be obtained by history taking. In many cases, itch increases in the evening when the sympathetic nerve activity decreased...

BACKGROUND: Patients suffering from chronic pruritus (CP) due to dry skin with are often applying emollients containing menthol. However, topical menthol may be irritating and of weak potency in severe pruritus. Two TRPM8 agonists, (1R,2S,5R)-N-(2-(2-pyridinyl)ethyl)-2-ispropyl-5-methylcyclohexancarboxamide and menthoxypropan-ediol, combined as Cooling Compound (CC) have shown stronger activation of TRPM8 than menthol. OBJECTIVES: Objective of this study was to evaluate the efficacy and safety of CC in alleviating pruritus in patients with dry itchy skin...

Pruritus (itch) is the most frequent skin symptom. It can be attributed to a skin disease in many cases. Furthermore pruritus may also be a precursing symptom or principal complaint of an internal, neurological or psychiatric disease. It has been observed that elderly patients are increasingly affected. In many cases pruritus has multifactorial causes. This requires careful diagnostics, including a detailed medical history and medical examination of the patient. Previous diseases and comorbidities need to be considered as possible causes, as well as current and previous drug intake...

The janus kinase-inhibitor oclacitinib is licensed for the control of pruritus associated with allergic skin diseases in dogs. Strikingly, it has been clinically reported that abrupt withdrawal of oclacitinib leads to a rebound pruritus in dogs. Therefore, the primary objective of this study was to mimic the rebound phenomenon of oclacitinib using a chronic pruritic mouse model of allergic contact dermatitis. Chronic allergic contact dermatitis was induced by repetitive toluene-2,4-diisocyanate (TDI) challenge in BALB/c mice...

Lichen sclerosus et atrophicus and limited systemic scleroderma (acrosclerosis) are inflammatory skin diseases that ultimately evolve into two distinct modes of atrophic scar formation, but which can easily be confused clinically. They are very rarely associated. The literature has reported cases in which lichen sclerosus was associated with various forms of scleroderma, but often with localized morphea. The characteristic histopathological picture of lichen sclerosus includes a thin epidermis, with orthohyperkeratosis and vascular degeneration in the basal layer, loss of elastic fibers, and band-like inflammatory infiltrate in the papillary dermis, while systemic sclerosis is characterized by excessive deposition of collagen in the dermis, accompanied by reduction in adnexal structures and their entrapment in collagen, and the presence of perivascular lymphocytic inflammatory infiltrate...

Lichen planus (LP) skin lesions are often accompanied by itch, but this symptom has not been thoroughly examined in LP. To better characterize itch in LP, 78 patients with LP were investigated. Itch was present in 94.9% of patients and was usually described as the most vexing symptom of LP. The severity of itch according to visual analogue scale score was 6.9 ± 2.8 points. Most patients experienced itching daily, pruritus episodes lasted longer than 1 min, and most often occurred in the evening. Itch was frequently described as burning and, for many patients, it was considered burdensome and annoying...

Although 5-HT has been implicated in cholestatic itch and antinociception, two common phenomena in patients with cholestatic disease, the roles of 5-HT receptor subtypes are unclear. Herein, we investigated the roles of 5-HT receptors in itch and antinociception associated with cholestasis, which was induced by common bile duct ligation (BDL) in rats. 5-HT-induced enhanced scratching and antinociception to mechanical and heat stimuli were demonstrated in BDL rats. 5-HT level in the skin and spinal cord was significantly increased in BDL rats...

Successful sleep onset and maintenance is associated with a reduction in core temperature, facilitated by heat loss at the distal periphery. Problems with initiating and maintaining sleep in children with eczema may relate to impaired thermoregulatory mechanisms, which also contribute to itching and scratching. Our hypothesis was that nocturnal distal skin temperature in eczematous children would be lower than controls, and would also be related to poor sleep quality. We compared overnight polysomnography and distal (finger) and proximal (clavicle) skin temperature in 18 children with eczema and 15 controls (6-16 years)...
