Background: Salmonella osteoarticular involvement is a rare complication, occurring in about 2% of the cases. Septic arthritis is exceedingly rare, involving only 0.2 % of all salmonellosis patients. Endocarditis is another complication that occurs in less than 0.8 % of cases. These complications are more likely to happen among immunocompromised patients.
Case Presentation: We report a previously healthy 25-year-old man who presented with left limb pain. He had been treated for brucellosis ten days earlier by his primary care physician. Arthrocentesis and subsequent hip-joint biopsy confirmed septic arthritis due to Salmonella. However, he was unresponsive to the treatment. We found no underlying immunosuppression. A trans-esophageal echo was performed due to the continued fever and positive blood cultures. It revealed Salmonella endocarditis of the naïve tricuspid valve. He was treated via arthrotomy and antimicrobials for four weeks. Follow-up after 20 months showed no underlying immunosuppression.
Conclusion: This case highlights that in patients with positive Salmonella blood cultures and a focus of infection compatible with Salmonellosis but unresponsive to treatment, searching for other foci of infection is necessary. Furthermore, physicians in endemic areas of brucellosis should consider other differential diagnoses in patients with fever and limping because any delay in diagnosing Salmonella septic arthritis can destroy the joint space with lifelong discomfort.

Nr4a1 and Nr4a3 redundantly control clonal deletion and contribute to an anergy-like transcriptome in auto-reactive thymocytes to impose tolerance in mice.

The Nr4a nuclear hormone receptors are transcriptionally upregulated in response to antigen recognition by the T cell receptor (TCR) in the thymus and are implicated in clonal deletion, but the mechanisms by which they operate are not clear. Moreover, their role in central tolerance is obscured by redundancy among the Nr4a family members and by their reported functions in Treg generation and maintenance. Here we take advantage of competitive bone marrow chimeras and the OT-II/RIPmOVA model to show that Nr4a1 and Nr4a3 are essential for the upregulation of Bcl2l11/BIM and thymic clonal deletion by self-antigen.

Introduction: The pharmacological management of inflammatory arthritis often requires choices that involve trade-offs between benefits, risks and other attributes such as administration route, frequency and cost. This living systematic review aims to inform international clinical guidelines on inflammatory arthritis by creating an evidence map of patient preference studies concerning the trade-offs in pharmacological management of inflammatory arthritis.
Methods And Analysis: We will include published and peer-reviewed full-text studies in any language that quantitatively assess preferences of patients for the pharmacological management of inflammatory arthritis (rheumatoid arthritis, spondyloarthritis and juvenile idiopathic arthritis).

Introduction: Folate receptors (FR) have been considered a convenient target for different radiopharmaceuticals in recent years. Multifarious Ga-labeled folate conjugates have been proposed as promising agents for the PET imaging of FR-overexpressing malignant neoplasms. In addition, radiolabeled folate-based conjugates can be effective for imaging non-tumor pathological foci characterized by a pronounced cluster of activated macrophages.

A wide variety of degenerative, inflammatory and infective arthropathies with overlapping clinical features can involve the knee joint. Due to its excellent soft tissue contrast resolution and multiplanar capability, magnetic resonance imaging (MRI) plays a significant role in early and accurate diagnosis of various arthropathies. In this article, we have provided a brief review of MRI features of various arthropathies involving the knee joint.

Background: The 2018 Infectious Disease Committee of the American Academy of Pediatrics stated that up to 3 weeks or less of doxycycline is safe in children of all ages. Our goal was to examine trends in doxycycline treatment for children with Lyme disease.
Methods: We assembled a prospective cohort of children aged 1 to 21 years with Lyme disease who presented to one of eight participating Pedi Lyme Net centers between 2015 and 2023.
