Rupture of the spleen is a serious medical condition manifesting as a sudden abdominal event, potentially life-threatening. Spontaneous spleen rupture is a rare condition. Atraumatic rupture of the spleen is a very unlikely condition. Risk factors include splenomegaly, hemato-oncological diseases, and infections, such as malaria or infectious mononucleosis. Extremely rare is splenic rupture described in autoimmune disease or vasculitis. There has been no reported case of spontaneous splenic rupture as a first manifestation of Churg- Strauss syndrome so far.

Torsion of an accessory spleen is a rare condition, and it is often difficult to diagnose. It frequently presents as an acute abdomen, especially in young individuals. Only several dozen cases have been reported so far, and instances of rupture are even rarer.

Background: Nuclear receptor subfamily 5 group A member 1 (NR5A1) plays pivotal roles in steroidogenesis and gonadal development. 46, XY disorder of sexual development (DSD) caused by NR5A1 mutations is a rare genetic condition. This study aimed to provide a comprehensive analysis of the clinical characteristics and molecular defects observed in 19 Chinese patients with NR5A1 variants, including assessing the deleterious effects of novel variants in vitro and evaluating their functional impact on the gonad and adrenal glands in vivo.

Article Synopsis
- Interleukin-1 is a key pro-inflammatory cytokine linked to the development of inflammatory diseases, where its absence in knockout mice leads to conditions like aortitis, arthritis, and dermatitis.
- Research shows that transferring T cells from these IL-1Ra KO mice into nude mice causes similar inflammatory diseases, raising questions about which specific T cell subsets are involved.
- The study found increased levels of a particular CD4+ T cell subset that produces granulocyte macrophage colony-stimulating factor (GM-CSF) in IL-1Ra KO mice, suggesting these cells play a significant role in the enhanced inflammation observed in these models.
Multi-organ gene expression analysis and network modeling reveal regulatory control cascades during the development of hypertension in female spontaneously hypertensive rat.

Hypertension is a multifactorial disease with stage-specific gene expression changes occurring in multiple organs over time. The temporal sequence and the extent of gene regulatory network changes occurring across organs during the development of hypertension remain unresolved. In this study, female spontaneously hypertensive (SHR) and normotensive Wistar Kyoto (WKY) rats were used to analyze expression patterns of 96 genes spanning inflammatory, metabolic, sympathetic, fibrotic, and renin-angiotensin (RAS) pathways in five organs, at five time points from the onset to established hypertension.
