Published: June 2024

Background: Progestogen hypersensitivity (PH) is a rare phenomenon reported in women with an immunologic response to rising progesterone levels in the luteal phase. This disease's rarity and clinical spectrum make it challenging to diagnose.

Case: In this case report, we will discuss a 14-year-old female with monthly oral mucositis and palmar lesions consistent with erythema multiforme. Over 2 years, she underwent an extensive multidisciplinary workup and was trialed on many different medical therapies.

Summary And Conclusion: The prevalence of PH has grown in the literature over the past decade. Due to progesterone's role in many biochemical pathways, the pathophysiology is complex. Although many modalities are efficacious for treating PH's cyclical eruptions, we propose treatment with a Janus kinase inhibitor when hormonal management alone is insufficient.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease characterized by the formation of nodules, abscesses, and fistulae at intertriginous sites. Pain, pruritus, malodor, and suppuration have a significant impact on quality of life for HS patients. Prevalence figures vary greatly in the literature from 0.

Fast, Present and Future of the Concept of Spondyloarthritis.

Curr Rheumatol Rep

January 2025

Rheumatologisches Versorgungszentrum Steglitz, Ruhr Universität Bochum, Schloßstr.110, 12163, Berlin, Germany.

Purpose Of Review: Axial spondyloarthritis (axSpA) is a rather prevalent chronic inflammatory rheumatic disease that affects already relatively young patients. It has been known better since the end of the nineteenth century but quite a lot has been learned since the early 60ies when the first classification (diagnostic) criteria for ankylosing spondylitis (AS) were agreed on. I have been part of many developments in the last 30 years, and I'm happy to have been able to contribute to the scientific progress in terms of diagnosis, imaging, pathophysiology and therapy.

Background: Evolving evidence suggests that patients undergoing treatment with Janus kinase inhibitors (JAKi) may face an increased risk of cardiovascular events, malignancies, and serious infections.

Objectives: We assessed cardiovascular, malignancy, and serious infection risks associated with JAKi use compared to tumor necrosis factor inhibitor (TNFi) use, which served as the active comparator, in patients with rheumatoid arthritis (RA) or ulcerative colitis (UC).

Methods: This study emulated a target trial using South Korea's nationwide claims database (2013-2023).
