Filter by:This is a multicenter, ambispective, low-interventional clinical study evaluating molecular genetic markers for non-invasive differential diagnosis of benign and malignant pigmented skin and mucosal neoplasms. In retrospective cohorts genetics markers will be identified. In prospective cohort non-invasive adhesive system will be tested to identify malignant or benign lesions with prespecified sensitivity and specificity compared to other non-invasive techniques (i.e. dermoscopy) and using histopathological examination as a "golden standard".
Study's objectives are to determine proportion of melasma cases in hyperthyroid patients and to compare severity of melasma before and after medications of three months hyperthyroid therapy using modified melasma area and severity index (mMASI) score. A quasi experimental (pre-post intervention) study was conducted in Jakarta in August 2019-February 2020.
Pigmentary disorders such as melasma, lichen planus pigmentosus and vitiligo can significantly affect patients' quality of life. Treatment responses are usually slow and typically have limited efficacy. In recent years, low level laser therapy has been an emerging treatment modality for androgenetic alopecia, acne, wound healing and photorejuvenation. This is a prospective, double-blind, split-body, randomized controlled trial assessing the efficacy of low level laser therapy with red light for pigmentary disorders such as, melasma, lichen planus pigmentosus and vitiligo.
It is a randomized controlled trial in which investigators determine the efficacy of tranexamic acid (TA) by mesotherapy in comparison to normal saline on participants having Melasma.
The primary objective is to evaluate the efficacy, of D.O.S.E formulations in the treatment of melasma and cutaneous signs of aging.
A randomized clinical trial will be done on 92 patients , randomly divided into two groups by lottery method to compare the efficacy and safety of topical silymarin cream 0.7% with topical 4% hydroquinone cream. Patients will be treated for 3 months and for the next 3 months will be followed up for relapse of melasma.
1.Melasma is a common acquired condition of symmetric hyperpigmentation, typically occurring on the face, with higher prevalence in females and darker skin types. Treatments for melasma include topical, oral, procedural, and combination treatments. 2.1064-nm Q-Switched laser is one of the most widely used lasers for pigmented diseases in recent years. This wavelength laser can be effectively absorbed by pigment, which leads to damage of pigment and melanocyte. Previous 1064-nm Q-Switched laser treatment of melasma requires the use of large flare and low energy scanning repeatedly in the lesion area, and the terminal reaction is reddish and skin lesion temperature increased by 2℃. So the course of treatment is even longer and is closely related to the treatment of the doctor's subjective judgment. Current 1064-nm Q-Switched fractional laser is designed with focusing lens and can be scanned only once for skin lesions during treatment. Further more, the treatment energy of a single point is higher and it has stronger ability to destroy melanin. Finally, 1064-nm Q-Switched fractional laser promotes the expulsion of melanin particles from the superficial dermis and basal epidermis. 3.Tranexamic acid (TA) works by inhibiting the plasmin-plasminogen pathway. Increase in plasmin in keratinocytes leads to increase in production of arachidonic acid and alpha-melanocyte-stimulating hormone (alpha-MSH) production. Thus, by inhibiting the plasmin pathway, TA results in decreased melanogenesis. Studies support the use of oral TA as an adjuvant therapy for in refractory cases of melasma or as a second-line or third-line agent, and there is some early evidence supporting the utility of oral TA as monotherapy. Overall, randomized controlled trials have found that combination treatment regimens using oral TA as adjunct therapy results in greater reduction of melasma.
The purpose of this study is to prospectively gather data on the efficacy and tolerability of spironolactone to treat refractory melasma and to compare treatment response of randomized 50 mg, 100mg, and 200mg per day dosing.
To compare the efficacy and safety of cryopeeling (using Liquid Nitrogen) and tranexemic acid (cyclokapron) versus chemical peeling (using TCA 20%) in treatment of melasma.
The objective of this study is to assess and compare the efficacy of tranexamic acid intradermal microinjection alone versus its combination with low power fractional CO2 laser in a sequential pattern. In all participants one half of the face will be randomly assigned to low power fractional CO2 laser while other side to Tranexamic acid intradermal microinjections on the 1st session. This split face session will be repeated every six weeks for 3 sessions. In addition, Tranexamic acid intradermal microinjections will be applied for full face at the 2nd and 4th week of each split face session. The response will be evaluated by the Melanin and erythema Indices which will be measured using reflectance spectrophotometer, Dermoscopy and photography before starting the study, two and four weeks after the last session. The sessions will take 4 months for each patient and another one month free of sessions for follow up.
