Study on Hypoallergenic Hair Dye
Contact DermatitisAllergy; Dermatitis1 morePermanent hair dyes are commonly used in over the counter direct to consumer products and within hair salons. Allergy, also known as contact dermatitis, to hair dye is a well known phenomenon. Herein, we seek to decrease the risks of allergy to hair dyes by testing a novel version of p-phenylenediamine (PPD) with less allergy potential.
MicroRNA-126 and Its Target VCAM-1Dermatitis to Nickel
Allergic Contact DermatitisBackground. Allergic Contact Dermatitis (ACD) is an inflammatory skin disease mediated by direct contact with allergens as nickel, the most common allergen, that may be related with epigenetic changes. Objective. Evaluate the miR-126 expression and its target VCAM-1, in the skin of patients with ACD to nickel. Methods. Fifteen patients with positive patch test to nickel were included, and the expression of miR-126 and VCAM-1 was evaluated by RT-qPCR.

Regulatory T Cells (Tregs) in Polymorphic Light Eruption
Polymorphic Light EruptionPsoriasis1 morePolymorphic light eruption (PLE) is a photodermatosis with an extremely high prevalence, particularly among young women (up to 20%). The disease is characterized through itchy skin lesions on sun-exposed body sites occurring after sun exposure mostly in spring and early summer. Its etiopathogenesis is unknown but resistance to UV-induced immunosuppression with subsequent immune reactions against skin photoneoantigens has been suggested. Regulatory T cells (CD4+CD25+FoxP3+) (Tregs), a subset of T helper cells, are crucial for the induction of immunosuppression. We will test the hypothesis that PLE patients show pathogenic fluctuating Treg levels and function and related parameters over the seasons of the year, possibly being responsible for lack of immune modulation and autoimmunity in PLE. Natural or medical photohardening may normalize Treg deficiency in PLE and lead to clinical adaption in summer. Better insight into the pathogenesis of PLE may give clues to develop new therapeutic strategies.
A Study To Assess Safety And Effectiveness Of Medrol In Contact Dermatitis In Indian Patients
DermatitisContactThis study will be a prospective, non-interventional, single arm and open label study, in patients with contact dermatitis requiring systemic steroid therapy with a purpose to obtain the real life effectiveness and tolerability of Medrol in treating contact dermatitis in Indian patients. Patients with contact dermatitis who have been prescribed for Medrol will be enrolled into the study and will be followed up for the resolution of symptoms
Occupational Hand Eczema - Testing of a Prevention-concept
Occupational Contact DermatitisRandomised controlled trial examining the effect of decreased waiting time for the first doctors' appointment, patient education, glove counselling and counselling at departments of social or occupational medicine on severity of hand eczema, quality of life, use of corticosteroids, and jobsituation 3-12 months after intervention in patients with suspected occupational contact dermatitis of the hands.
Vulvar Contact Dermatitis Resulting From Urine Incontinence
Urinary IncontinenceVulvar Pruritus1 moreVulvar contact dermatitis (VCD) is a common problem presenting as vulvar pruritus, burning or irritation. Its estimated prevalence is 20-30% in vulvar clinics, but the prevalence in the general population is unknown. Contact dermatitis is an inflammation of the skin resulting from an external agent that acts as an irritant or as an allergen. The skin reaction may be acute, subacute or chronic, resulting from prolonged exposure to weak irritating substances. The most common form of VCD is irritant contact dermatitis, and it usually presents as vulvar itch. The causes that contribute to VCD are increased sensitivity of the vulvar skin to irritants compared to other body parts, decrease in the skin barrier function due to exposure to sweat, urine and vaginal discharge and constant friction of the vulvar area. In menopausal women, lack of estrogen contributes to tissue atrophy and thinning, and may increase the effect of irritants on the vulvar skin. One of the most common irritating substances that cause VCD is urine. The phenomenon of urine-induced VCD is known as" diaper rash" in babies, and it was also described in bedridden patients using diapers constantly. Women with urine incontinence (UI), a problem that its prevalence in women increases with aging, may use constantly panty liners or pads to prevent urine leakage. The urine is being absorbed in the pad, and the vulvar skin is continually exposed to urine. This can cause VCD, similar to diaper rash. The prevalence of this phenomenon in the general population is unknown. The patients complain of itch, burning or irritation of the vulvar skin, and on exam erythema, edema and irritated skin are found. As most patients do not connect between UI to their vulvar disorder, and as most care-givers do not ask routinely about UI, the vulvar symptoms are mistakenly attributed to yeast infection or other factors. As the cause to the vulvar complaints is not recognized, patients do not receive proper treatment that requires primary management of UI. The aim of the study is to evaluate the prevalence of VCD in women with UI and to recognize risk factors for UI induced VCD.
Histopathological Comparison Between Superficial Pressure Ulcers and Incontinence-associated Dermatitis...
Pressure UlcerIncontinence-associated Dermatitis2 moreThis study aims to identify differences and similarities between superficial pressure ulcers (category II and III) and incontinence-associated dermatitis (category IIA) at tissue level. Skin biopsies will be obtained from 30 patients with pressure ulcers (n = 10), incontinence-associated dermatitis (n = 10), and combined lesions (n = 10). The results from the histopathologic examination will be compared with the clinical diagnosis by wound care experts, which will be based on photographs and relevant patients' characteristics.
Quaternium-15, Use Test
Allergic Contact Dermatitis Towards Quaternium-15The study is required by the FDA as part of a post-marketing commitment. The purpose of the study is to compare the reactivity of the TRUE Test quaternium-15 patch and a real use exposure.The subjects will wear the patch test for 48 hours and reading will be performed day 3 or 4. The use test will be applied from day 3 or 4 and untill reaction appears. Reactions from respectively TRUE Test and use test will be compared using the McNemar Change Test.
Molecular and Cellular Characterization of Spongiotic Dermatitis
Atopic DermatitisPsoriasis1 moreSpongiotic dermatitis is the histopathologic diagnosis commonly issued by dermatopathologists that encompasses atopic dermatitis, contact dermatitis, and other forms of eczematous dermatitis. The information obtained will assist in development of diagnostic methods for differentiation of the types of spongiotic dermatitis. This study also has the potential to lead to the dissection of pathologic pathways involved in these diseases and development of novel therapeutic agents.
