BACKGROUND: Atopic dermatitis (AD) is a chronic, pruritic inflammatory skin disease in which type 2 allergic inflammation plays an important role. Collagen tripeptide (CTP) is a functional collagen fraction with a high content of Gly-X-Y tripeptides. OBJECTIVE: To examine the effect of CTP on inflammation in AD. METHODS: Levels of inflammatory cytokines and chemokines, such as thymus- and activation-regulated chemokine (TARC), macrophage-derived chemokine, and thymic stromal lymphopoietin (TSLP), were examined in human keratinocytes supplemented with or without CTP under AD-like inflammation...

Infestation with Sarcoptes scabiei var. hominis is a common human parasitic affliction endemic in tropical developing countries. Scabies is transmitted by close person-person contact, and outbreaks have been reported in reception centers for asylum seekers. Scabies presents clinically as extremely pruritic excoriated papules and linear burrows in the skin. This infestation predisposes to bacterial skin infections that can result in serious complications affecting the kidneys and possibly the heart. Treatment of individuals with scabies and their close contacts involves the use of antiparasitic agents...

Chronic spontaneous urticaria (CSU) is a common skin disorder characterized by daily or almost daily recurring skin edema and flare with itch. Recently, the activation of the blood coagulation cascade has been suggested to be involved in CSU, but the trigger of the coagulation cascade remains unclear. In this article, we review recent understanding of the relationship between the pathogenesis of CSU and extrinsic coagulation reactions. In CSU, vascular endothelial cells and eosinophils may play a role as TF-expressing cells for activating the extrinsic coagulation pathway...

Infection is common in many chronic, inflammatory skin conditions but is often difficult to treat, in part due to growing bacterial resistance to antibiotics. Liposomal polyvinyl-pyrrolidone (PVP)-iodine hydrogel has a unique mode of action, combining the antiseptic and anti-inflammatory actions of PVP-iodine with the drug delivery and moisturizing properties of liposomes. We investigated the utility of liposomal PVP-iodine to treat infective dermatoses. In this prospective, single-arm (uncontrolled), open-label Phase II pilot study, patients with acne vulgaris (n=30), atopic dermatitis (n=20), impetigo contagiosa (n=10), and rosacea (n=10) received PVP-iodine (3%) hydrogel for ≤4 weeks...

AIMS: CXCL1 is a chemokine with pleiotropic effects, including pain and itch. Itch, an unpleasant sensation that elicits the desire or reflex to scratch, it is evoked mainly from the skin and implicates activation of a specific subset of IB4+, C-type primary afferents. In previous studies we showed that acute application of CXCL1 induced a Ca(2+) influx of low amplitude and slow kinetics in a subpopulation of transient receptor potential vanilloid type 1 (TRPV1)+/isolectin B4 (IB4)+dorsal root ganglia neurons which also responded to other itch-inducing agents...

Transient receptor potential (TRP) ion channels were first characterized on neurons, where they are classically implicated in sensory functions; however, research in recent decades has shown that many of these channels are also expressed on non-neuronal cell types. Emerging findings have highlighted the role of TRP channels in the skin, where they have been shown to be important in numerous cutaneous functions. Of particular interest is TRPV3, which was first described on keratinocytes. Its functional importance was supported when its gain-of-function mutation was linked to Olmsted syndrome, which is characterized by palmoplantar keratoderma, periorifacial hyperkeratosis, diffuse hypotrichosis and alopecia, as well as itch...

Sensitive skin is a condition characterized by stinging, burning and itching sensations. The diagnosis, pathophysiology and treatment of sensitive skin are still under discussion. In the last years, studies on its epidemiology have been performed, showing a high prevalence and impact on quality of life. Brazilian population was also considered in these studies. Cosmetics, climate changes and skin barrier impairment are the main factors that contribute for skin hyperreactivity. New studies are trying to bring new knowledge about the theme...

BACKGROUND: Delusional parasitosis (DP) is an uncommon psychiatric disorder. Patients suffering from this disorder have the fixed false belief of being infested by a parasite. Because of this condition, patients mainly consult with dermatologists or general practitioners. They are often reluctant to see a psychiatrist and to take treatment with antipsychotics because of their belief. The following describes the case of a woman who has the particularity that the DP started a few days after sertraline interruption...

BACKGROUND: Post-thrombotic syndrome (PTS) is a long-term complication of deep vein thrombosis (DVT) that is characterised by chronic pain, swelling, and skin changes in the affected limb. One of every three people with DVT will develop post-thrombotic complications within five years. Several non-pharmaceutical measures are used for prevention of post-thrombotic syndrome during the acute phase of DVT. These include elevation of the legs and compression therapy. Clinicians and guidelines differ in their assessment of the utility of compression therapy for treatment of DVT...

WHAT IS KNOWN AND OBJECTIVE: Scabies is recognized as a neglected tropical disease responsible for a substantial health and economic burden, especially in resource-poor communities around the world. COMMENT: There are relatively few current treatment options for scabies, and they possess important limitations. The treatments are ineffective in preventing relapse, inflammatory skin reactions and associated bacterial skin infections. There are also safety concerns, especially in children and pregnant women...

REVIEW

Recessive dystrophic epidermolysis bullosa is a disorder marked by skin and mucosal blistering after minimal trauma. Even the most routine procedures in the hospital, if done incorrectly, can precipitate extensive skin loss, pain, and scarring. Most providers have little experience working with patients with this degree of skin fragility. When a person with recessive dystrophic epidermolysis bullosa is admitted to the hospital, there are multiple considerations to keep in mind while strategizing an effective care plan: avoidance of new blisters with a "hands-off" approach; careful consideration of all indwelling devices; symptomatic management of pain, itch, and anxiety; coordination of dressing changes; aggressive treatment of skin infections; environmental and staffing considerations; and awareness of other chronic complications that affect care, such as anemia, malnutrition, and chronic pain...

Dermanyssus gallinae is one of the important hematophagous ectoparasite species of poultry like chicken, pigeon and wild bird species. These ectoparasites in the form of nymphs or adults who can not find their hosts are also seen in mammals and even in humans. For this reason, they are considered as important for public health. The ectoparasite causes a clinical condition named gamasoidosis among pet owners and people who live or work close to animal shelters, barns and chicken farms. Pruritus dermatitis is also caused by D...
