Background: Pemphigus vulgaris (PV) is an autoimmune bullous disease involving both the skin and mucus membranes. Infiltrating CD4+ and CD8+ T-lymphocytes may have a vital role in its pathogenesis. The autoimmune bullous skin disorder intensity score (ABSIS) was proposed for clinical evaluation and scoring of PV patients. https://www.roneverhart.com/Ferrofish-A32pro-32-Channel-AD-DA-Converter-with-MADI-and-ADAT-p18115/
