Uterine preservation in pyomyoma complicating uterine artery embolisation.

Pyomyoma, a rare complication of uterine artery embolisation (UAE) for symptomatic fibroids, can closely mimic post-embolisation syndrome (PES), which typically presents with pain, fever and leucocytosis within the first week. Differentiating PES from pyomyoma is critical, as pyomyoma carries a higher risk of severe complications. We report a case of an unmarried nulliparous woman who developed pyomyoma following UAE for fibroids.

TGF-beta plays dual roles in immunity and pathogenesis in leishmaniasis.

Transforming growth factor-beta (TGF-β), displaying a dual role in immunosuppression and pathogenesis, has emerged as a key regulator of anti-leishmanial immune responses. In Leishmania infections, TGF-β drives immune deviation by enhancing regulatory T-cell (T-reg) differentiation and inhibiting macrophage activation, suppressing critical antiparasitic responses. This cytokine simultaneously promotes fibroblast proliferation, extracellular matrix production, and fibrosis in infected tissues, which aids in wound healing but impedes immune cell infiltration, particularly in visceral leishmaniasis, where splenic disorganization and compromised immune access are notable.
