Staphylococcus aureus is the most common causative organism in pediatric septic arthritis, with methicillin-resistant Staphylococcus aureus (MRSA) being responsible for a significant portion of these infections. Early identification and initiation of proper treatment may improve outcomes by minimizing potential morbidity. The purpose of this study was to identify variables obtained on initial patient presentation associated with MRSA septic arthritis. Sixteen factors were retrospectively evaluated in 109 consecutive pediatric patients diagnosed with culture-confirmed septic arthritis...

Introduction: Although synthetic and biologic disease-modifying antirheumatic drugs are available, many patients with rheumatoid arthritis have a difficult-to-control disease and need other treatment options. Repository corticotropin injection (RCI) may alleviate symptoms and exacerbations in patients with refractory disease. Methods: Nine patients with refractory rheumatoid arthritis were included in this study. Patients were maintained on their baseline therapies with a minimum of 7...

RATIONALE: Synovial cysts are well known in rheumatoid arthritis (RA), and most common in the popliteal fossa. They may produce lots of local symptoms and complaints, which may present initially as an unrelated clinical condition. Few studies have reported multiple extra-articular synovial cysts (MESCs) in the RA patients. Early diagnosis is crucial for patient treatment. PATIENT CONCERNS: A 50-year-old man without any special clinical histories found a soya bean size bump at the left elbow medially, then multiple lumps were found at bilateral elbows and gradually increasing...

BACKGROUND: Axillary lymph nodes (ALNs) are often seen on chest computed tomography (CT) in rheumatoid arthritis (RA) patients. Early reports described lymphadenopathy as one of the systemic manifestations rather than regional lymphadenopathy secondary to drainage from the affected joints. Subsequently, the importance of the immunological events occurring in draining lymph nodes in the development of arthritis was documented. OBJECTIVE: To identify the relationships of local disease activity and background characteristics, including systemic disease activity, systemic disease activity, with axillary lymphadenopathy (AL) in RA using CT...

Palmar fasciitis and polyarthritis (PFPA) is an uncommon disorder clinically characterized by rapidly developing bilateral arthritis of the hands and fasciitis of the palms. This cancer-associated syndrome, primarily linked to ovarian cancer, has also been associated with multiple different malignancies. PFPA symptoms usually precede the detection of ovarian cancer. In all patients from case series and single case reports described, ovarian cancer is already present at an advanced stage. Therefore, the authors aimed to present a case and systematically review available evidence on the association between PFPA and ovarian cancer, as gynecological oncologists...

IL-36 cytokines have recently emerged as mediators of inflammation in autoimmune conditions including psoriasis vulgaris (PsV) and generalized pustular psoriasis (GPP). This study used RNA-seq to profile the transcriptome of primary epidermal keratinocytes (KCs) treated with IL-1B, IL-36A, IL-36B, or IL-36G. We identified some early IL-1B-specific responses (8 h posttreatment), but nearly all late IL-1B responses were replicated by IL-36 cytokines (24 h posttreatment). Type I and II interferon genes exhibited time-dependent response patterns, with early induction (8 h) followed by no response or repression (24 h)...

BACKGROUND: Dermatologists are recommended to ask psoriasis patients about musculoskeletal complaints to allow early detection and treatment of psoriatic arthritis (PsA). Screening tools have been developed to help identifying patients warranting further rheumatologic assessment, but evidence suggests room for improvement in their diagnostic value and ease of use for outpatient practice. OBJECTIVE: To develop and internally validate a brief tool for dermatologists to screen patients to refer to a rheumatologist for PsA diagnosis...

BACKGROUND: Accurate measurements of rheumatoid factors (RFs), autoantibodies binding IgG, are important for diagnosing rheumatoid arthritis (RA) and for predicting disease course. Worldwide, various RF assays are being used that differ in technique and target antigens. We studied whether assay choice leads to clinically important discrepancies in RF status and level. METHODS: RF measurements using four commercial RF assays were compared in 32 RF+ samples. Using enzyme-linked immunosorbent assays (ELISAs), the influence of the target antigen source - human IgG (hIgG) versus rabbit IgG (rIgG) - on measured RF levels was investigated in arthralgia patients and RA patients...

OBJECTIVE: Neutrophils are the most abundant innate immune cells in the blood, however little is known about their role in (acquired) chronic autoinflammatory diseases. We investigated neutrophils in systemic onset Juvenile Idiopathic Arthritis (sJIA), a prototypical multifactorial autoinflammatory disease, characterized by arthritis and severe systemic inflammation. METHODS: We analyzed 50 sJIA patients at disease onset and during remission on recombinant IL-1 receptor antagonist (rIL-1RA, anakinra)...

Protease inhibitors have important function during homeostasis, inflammation and tissue injury. In this study, we described the role of Schistosoma mansoni SmKI-1 serine protease inhibitor in parasite development and as a molecule capable of regulating different models of inflammatory diseases. First, we determine that recombinant (r) SmKI-1 and its Kunitz domain but not the C-terminal region possess inhibitory activity against trypsin and neutrophil elastase (NE). To better understand the molecular basis of NE inhibition by SmKI-1, molecular docking studies were also conducted...

Over-the-counter analgesics are used globally for the relief of acute pain. Although effective, these agents can be associated with adverse effects that may limit their use in some people. In the early 2000s, observations from clinical trials of prescription-strength and supratherapeutic doses of nonselective and cyclooxygenase-2-selective nonsteroidal anti-inflammatory drugs (NSAIDs) raised safety concerns regarding the risk of cardiovascular adverse effects with the use of these medications. Subsequently, the US Food and Drug Administration mandated additional study of the cardiovascular safety of NSAIDs for a more comprehensive understanding of their risk...

Rheumatoid arthritis (RA) is a chronic, inflammatory, autoimmune disease that primarily affects the joints and is associated with autoantibodies that target various molecules including modified self-epitopes. The identification of novel autoantibodies has improved diagnostic accuracy, and newly developed classification criteria facilitate the recognition and study of the disease early in its course. New clinical assessment tools are able to better characterize disease activity states, which are correlated with progression of damage and disability, and permit improved follow-up...

BACKGROUND: Most hand surgeons use a dorsal approach for proximal interphalangeal (PIP) joint implant arthroplasty. However, a volar approach offers the advantage of no disturbance to the extensor mechanism, thus allowing early initiation of active range of motion. We examined our results in patients who underwent PIP joint arthroplasty via a volar approach. METHODS: Using a retrospective chart review, we evaluated the outcomes of patients undergoing PIP joint arthroplasty through a volar approach between 2001 and 2005 by 3 fellowship-trained hand surgeons at our institution...

BACKGROUND: Arthrodesis of the first metatarsophalangeal joint (MTPJ) is a common procedure to treat significant first MTPJ arthritis. However, dorsal plates used for this have been associated with high incidence of metalwork removal. The IOFIX (Intra-Osseous FIXation) is a fixed angle device that is noted to provide a more uniform compression over a larger aspect of the fusion surfaces than a screw construct alone with the advantage of minimizing soft tissue irritation which can reduce the need for subsequent implant removal...
