More recently, their immunosuppressive and anti-inflammatory properties have been identified for the treatment of several dermatologic conditions.

The PubMed® and Scopus® databases were subsequently reviewed in December 2017 using MeSH and keywords, such as cannabinoid, THC, dermatitis, pruritus, and skin cancer. The search yielded reports on the therapeutic role of cannabinoids in the management of skin cancer, acne vulgaris, pruritus, atopic and allergic contact dermatitis, and systemic sclerosis. While cannabinoids have exhibited efficacy in the treatment of inflammatory and neoplastic skin conditions, several reports suggest pro-inflammatory and pro-neoplastic properties.

Recent scientific discoveries have elucidated the physiology associated with pruritus. Combined with clinical and experimental trials with immune-modulatory agents, chronic pruritus now has novel treatment options with known mechanisms of action. This review goes over recent scientific progress in understanding the molecular mechanisms governing pruritus, the cross-talk between the immune and nervous systems that regulate itch, and central nervous pathways and projections affected by itch. In light of these recent discoveries, we briefly discuss a growing body of data from relevant clinical trials investigating immunomodulatory drugs targeting specific interleukin receptors (IL-4/13/31) and intracellular signaling (e.g., Janus kinase) pathways. We focus on the physiological processes that control this complex physical and emotional experience, as well as the role of newer drugs used to treat chronic itch.</p>","PeriodicalId":21829,"journal":{"name":"Skin therapy letter","volume":"23 5","pages":"5-9"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36519746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing a new technological platform for the non-invasive profiling of skin, the assay analyzes samples collected from adhesive patches for expression of two key genes (PRAME and LINC00518) known to be overexpressed in melanoma. The test result is binary (positive/negative) based on the detection of one or both genes. PLA positive cases are generally biopsied to establish the histopathologic diagosis, while PLA negative cases are considered for ongoing monitoring. The combination of visual inspection with histopathology, the current gold standard for melanoma diagnosis, has a relatively low negative predictive value (NPV) of approximately 83%, meaning that 17% of melanomas will be interpreted as benign lesions. In contrast, the PLA has a very high NPV (>99%). Further, with its high specificity (69-91%), use of the PLA can reduce the number of false positive samples subjected to histopathology review. By adding the PLA to the current care pathway, the number of surgical biopsies needed to find a melanoma (number needed to biopsy) is markedly reduced from 20-25 biopsies for dermatologists and 39 biopsies for physician assistants, to an average of 2.7. To date, unnecessary surgical procedures of benign lesions have been reduced by 88% based on a sample of more than 20,000 analyzed cases. This has resulted in fewer missed melanomas and significant cost savings to health care systems.</p>","PeriodicalId":21829,"journal":{"name":"Skin therapy letter","volume":"23 5","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36519745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, adherence to topical treatment remains a challenge, as the daily application creates a significant treatment burden. New topical therapeutic options need to offer higher efficacy and better patient acceptability, including easier application, to reduce treatment burden and enhance patient adherence. Topical foam vehicles are innovative alternatives to creams and ointments, addressing many patient challenges with traditional vehicles. Well-designed foam vehicles are easily spread over large areas of the skin, while importantly not leaving a greasy or oily film on the skin after application. Calcipotriol/betamethasone diproprionate aerosol foam is a new psoriasis treatment option that is rapidly effective, offers greater efficacy versus ointment and gel formulations, and has been shown to increase patient treatment satisfaction. Hence, by addressing the several crucial unmet clinical needs in patients with mild-to-moderate psoriasis, this optimized foam formulation is poised to improve treatment follow-through.</p>","PeriodicalId":21829,"journal":{"name":"Skin therapy letter","volume":"23 4","pages":"5-9"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36376566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
