Description: This episode explores the diagnosis and treatment of dermatomyositis (DM) and polymyositis (PM), two key subtypes of idiopathic inflammatory myopathies (IIMs), as comprehensively detailed in the UpToDate articles. It covers the full spectrum of therapeutic strategies, from initial treatments like glucocorticoids and conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) to advanced options for recurrent or resistant cases, such as intravenous immunoglobulin (IVIG) and rituximab. The podcast also delves into ancillary management approaches, including physical therapy and risk mitigation strategies, all based on the latest UpToDate insights. Each subtopic concludes with a key takeaway, summarized as "if you can't remember everything, remember this," to help residents retain critical information for clinical practice.
