While one popular scale exists, it is specific to facial hyperpigmentation related to acne.<\/p>\n<p>A new <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0190962224005000?via%3Dihub\">study<\/a> has validated a novel scale for hyperpigmentation, the Post-inflammatory Dyspigmentation Area and Severity Index (PIDASI), in a diverse U.S. population of varying skin tones. Additionally, these same researchers developed and validated a new, simpler scale for this condition they called the Post Inflammatory Hyperpigmentation Area and Severity Index (PIHASI) that allows for better and easier characterization of the condition.<\/p>\n<p><img loading=\"lazy\" src=\"\/camed\/files\/2015\/06\/Neelam-Vashi-1.jpg\" alt=\"head and shoulders image of Dr. Vashi wearing a white coat, smiling broadly\" class=\" wp-image-81221 alignleft\" width=\"150\" height=\"150\" srcset=\"https:\/\/www.bumc.bu.edu\/camed\/files\/2015\/06\/Neelam-Vashi-1.jpg 180w, https:\/\/www.bumc.bu.edu\/camed\/files\/2015\/06\/Neelam-Vashi-1-150x150.jpg 150w, https:\/\/www.bumc.bu.edu\/camed\/files\/2015\/06\/Neelam-Vashi-1-100x100.jpg 100w\" sizes=\"(max-width: 150px) 100vw, 150px\" \/>\u201cOur study demonstrates that both the PIDASI and PIHASI tools perform well in patients of a variety of skin types with post-inflammatory hyperpigmentation and are reliable and valid alternatives to the commonly used metric to measure the severity of skin changes from inflammatory diseases,\u201d explained corresponding author <a href=\"https:\/\/profiles.bu.edu\/Neelam.Vashi\">Neelam Vashi<\/a>, MD, associate professor of dermatology at the school and director of the Boston University Cosmetic and Laser Center at Boston Medical Center.<\/p>\n<p>Patients with hyperpigmentation were examined using colorimetry, an objective method of color characterization and standardized photographs. Expert dermatologists and dermatology residents then graded the hyperpigmentation on three scales; the scale they created (PIHASI), the PIDASI, and the industry standard. They found that both PIDASI and PIHASI corresponded to objective measurements of disease severity.<\/p>\n<p>According to the researchers, the PIHASI scale will allow providers to better characterize a patient&#8217;s hyperpigmentation and will be vital in hyperpigmentation research to better quantify response to treatment. \u201cAs the scale is simpler than the PIDASI, it can also be used in clinics during patient encounters to understand improvement in hyperpigmentation across time,\u201d said Vashi.<\/p>\n<p>These findings appear <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0190962224005000?via%3Dihub\">online<\/a> in the Journal of the American Academy of Dermatology.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>New scale will allow providers to better characterize a patient&#8217;s hyperpigmentation to better quantify response to treatment.<\/p>\n","protected":false},"author":903,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[90],"tags":[],"_links":{"self":[{"href":"https:\/\/www.bumc.bu.edu\/camed\/wp-json\/wp\/v2\/posts\/120399"}],"collection":[{"href":"https:\/\/www.bumc.bu.edu\/camed\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.bumc.bu.edu\/camed\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.bumc.bu.edu\/camed\/wp-json\/wp\/v2\/users\/903"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bumc.bu.edu\/camed\/wp-json\/wp\/v2\/comments?post=120399"}],"version-history":[{"count":3,"href":"https:\/\/www.bumc.bu.edu\/camed\/wp-json\/wp\/v2\/posts\/120399\/revisions"}],"predecessor-version":[{"id":142981,"href":"https:\/\/www.bumc.bu.edu\/camed\/wp-json\/wp\/v2\/posts\/120399\/revisions\/142981"}],"wp:attachment":[{"href":"https:\/\/www.bumc.bu.edu\/camed\/wp-json\/wp\/v2\/media?parent=120399"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.bumc.bu.edu\/camed\/wp-json\/wp\/v2\/categories?post=120399"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.bumc.bu.edu\/camed\/wp-json\/wp\/v2\/tags?post=120399"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
