Atypical femoral fracture (AFF) is generally a rare complication of long-term use of bisphosphonate (BP); glucocorticoid (GC) use and Asian race are also risk factors. Femoral localized periosteal thickening (LPT, also termed "beaking") of the lateral cortex often precedes AFF. This cohort study investigated the incidence of LPT and AFF and their clinical courses over 10 yr in patients with autoimmune inflammatory rheumatic diseases (AIRDs) treated with BP and GC.

Article Synopsis
  • - Adult-onset Still's disease (AOSD) is characterized by symptoms like fever, rash, and joint pain due to autoinflammation, and the patient's complement titer was notably low during her condition's onset.
  • - The female patient, in her 60s, presented with elevated white blood cell counts and ferritin levels, but tested negative for common autoimmune markers and infections, leading to a diagnosis of hypocomplementemia.
  • - Despite receiving several standard treatments including corticosteroids, her condition did not improve until she was treated with intravenous cyclophosphamide, which resulted in remission and normalized her complement levels, highlighting the potential of low complement levels as an indicator of severe disease activity and treatment resistance.

Article Synopsis
  • A study was conducted to evaluate the link between anti-ribosomal P antibody (anti-RibP) levels and disease activity in Japanese patients with systemic lupus erythematosus (SLE), including 80 individuals from Niigata University Hospital.
  • Results showed that 30 patients tested positive for anti-RibP, which correlated with more severe symptoms like skin rashes and increased inflammatory cytokine levels, particularly in younger patients.
  • The findings suggest that anti-RibP, especially its IgG3 subclass, is significantly associated with SLE severity and could be used as an indicator for disease management, indicating the need for higher initial treatment doses in certain cases.

Article Synopsis
  • Adrenocortical carcinoma (ACC) is a rare and deadly cancer characterized by a specific subtype called CIMP-high, which is associated with abnormal DNA methylation and mutations in β-catenin.
  • Research shows that the differentiation in CIMP-high ACC relies on a complex interaction between β-catenin and certain transcription factors, maintaining its cancerous state throughout its development.
  • Targeting the epigenetic regulator EZH2 can disrupt these interactions, leading to reduced tumor growth and presenting a potential therapeutic approach for treating β-catenin-driven cancers.

Background: Viral hepatitis C is a significant public health challenge. The disease may remain clinically silent in both acute and chronic forms, and chronic infections may progress to advanced disease such as cirrhosis and hepatocellular carcinoma, requiring costly treatment, compromising the patient's quality of life and even leading to death. For this reason, it is one of the most frequent indications for liver transplantation.

Adrenocortical tumors (ACT) in the adult and pediatric population are generally considered distinct entities due to differences in molecular events related to tumorigenesis, clinical presentation, and outcome. Furthermore, pathological criteria used for diagnosis and prognostication of ACT in adults are usually inadequate for predicting the biological behavior of ACT in children. Here, we analyzed 146 adult and 44 pediatric (< 15y/o) ACT with long-term clinical follow-up and furthered current evidence on the clinical and pathological differences between pediatric and adult tumors.
