Introduction: Adult cases of septic arthritis due to concomitant persistent osteomyelitis are incredibly uncommon. This study describes a rare example of septic arthritis in an adult's knee joint caused by long-term femur osteomyelitis. A cement rod laced with antibiotics proved to be an effective treatment for the illness.
Case Report: A case of septic knee arthritis caused by reactivated chronic osteomyelitis is described in this study. Initial radiographs revealed an osteolytic lesion, prompting further imaging, including a magnetic resonance imaging, which verified the diagnosis. To treat the infected intra-articular knee joint and ream the femoral intramedullary canal, we chose open debridement over arthroscopic surgery based on the patient's history, physical examination, and imaging data. To close the dead space and remove the infection, a cement rod impregnated with antibiotics was placed into the medullary cavity, in addition to administering long-term antibiotic treatment. This approach was successful in eradicating the infection. Following a period of rehabilitation, the patient regained the ability to walk independently.
Conclusion: Cement rods infused with antibiotics are effective for delivering high doses of antibiotics locally while providing structural support to the bone. Over the last three decades, they have demonstrated encouraging outcomes in treating infections, and due to their affordability, simplicity, and effectiveness, they remain an excellent treatment option. Here, we highlight the use of colistin in making antibiotic-coated cement rods for the eradication of chronic, long-standing infection.

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.
