OBJECTIVE: Rheumatoid Arthritis (RA) is an autoimmune inflammatory disease that leads to local and systemic arthritis and bone loss. Exploring genetic markers of candidate genes in osteoporosis and inflammatory cytokine genes could be a useful tool for the early identification of bone loss and fracture risk in RA patients. The target of this study is the evaluation and correlation between of Single Nucleotide Polymorphisms (SNPs) of Vitamin D Receptor (VDR) and possible effects on bone loss in RA...

BACKGROUND: The contribution of smoking to rheumatoid arthritis (RA) is hypothesized to be mediated through formation of anti-citrullinated protein antibodies (ACPA). In RA, however, autoantibodies such as ACPA, rheumatoid factor (RF), and anti-carbamylated protein antibodies (anti-CarP) often occur together, and it is thus unclear whether smoking is specifically associated with some autoantibodies rather than others. We therefore investigated whether smoking is only associated with ACPA or with the presence of multiple RA-related autoantibodies...

INTRODUCTION: Toxic shock syndrome occurs from dysregulation of host inflammatory responses. Toxin- producing strains of Group A streptococcus cause TSS. Ischemic optic neuropathy rarely complicates septic shock. We present a rare case of streptococcal pharyngitis complicated by septic arthritis and TSS with reversible blindness due to non-arteritic ischemic optic neuropathy. CASE: A 28-year-old man drove to our ED with exudative pharyngitis. A rapid streptococcal test was positive...

BACKGROUND: The risk of development of rheumatoid arthritis (RA) could be affected by immune activation in obesity. Our objective was to evaluate the association between obesity in general, and abdominal obesity, and the risk for subsequent development of RA. METHODS: In two large population-based, prospective cohorts, 557 cases (mean age at RA symptom onset 58, SD 10 years, 68% women) who subsequently developed RA and 1671 matched controls were identified. From a health examination antedating symptom onset (median 5...

BACKGROUNDS: Patients with rheumatoid arthritis (RA) have increased risk of sudden cardiac death (SCD), which is two-fold higher than general population. The driving cause of SCD was considered due to lift-threatening arrhythmia where systemic inflammation acts as the pathophysiological basis linking RA to autonomicdysfunction. METHODS: To assess the sympathetic over-activity of "inflammatory reflex", we measured heart rate variability (HRV) in a rat collagen-induced arthritis (CIA) model, whose arthritis is induced in Lewis rats by intradermal injection of emulsion of type II collagen...

Although the gut microbiome plays important roles in host physiology, health and disease(1), we lack understanding of the complex interplay between host genetics and early life environment on the microbial and metabolic composition of the gut. We used the genetically diverse Collaborative Cross mouse system(2) to discover that early life history impacts the microbiome composition, whereas dietary changes have only a moderate effect. By contrast, the gut metabolome was shaped mostly by diet, with specific non-dietary metabolites explained by microbial metabolism...

Background. Renal-limited myeloperoxidase vasculitis with simultaneous rheumatoid arthritis is reported as a rare occurrence. Review of literature suggests that most patients had a diagnosis of rheumatoid arthritis for several years prior to presenting with renal failure from myeloperoxidase vasculitis. Case Presentation. A 58-year-old Caucasian male presented to the hospital experiencing malaise, fevers, decreased oral intake, nausea, and vomiting for one week duration. His past medical history consisted of newly diagnosed but untreated rheumatoid arthritis, hypertension, and non-insulin-dependent diabetes mellitus...

INTRODUCTION: Isolated patellofemoral (PF) arthritis is rare, and there is no complete agreement about the best surgical treatment. The operative treatments are total knee arthroplasty and patellofemoral replacement (PFR). The incidence of many early complications of PF arthroplasty has decreased with the introduction of newer designs. Nowadays, the main cause of revision surgery is the progression of tibiofemoral osteoarthritis. In the past, PF arthroplasty was contraindicated in patients with evidence of osteoarthritis or pain in medial or lateral tibiofemoral compartments...

In a Sidonian sarcophagus, from the Late Antique/early Christian period, skeletal remains of two persons were found. One of them, male, 30-50 years old, was found almost completely ankylosed, with highly osteoporotic bones and prominent erosion of joint surfaces. We diagnosed rheumatoid arthritis based on the eroded odontoid process, mandibular condyles, distal humerus, proximal and distal ulna, as well ankylosed hand and foot bones. Despite the fact that ankyloses of vertebrae and sacroiliac joint could point towards ankylosing spondylitis, the lack of typical vertebral ankyloses and new bone formation led to exclusion...

Football and rugby athletes are at increased risk of finger injuries given the full-contact nature of these sports. Some players may return to play early with protective taping, splinting, and casting. Others require a longer rehabilitation period and prolonged time away from the field. The treating hand surgeon must weigh the benefits of early return to play for the current season and future playing career against the risks of reinjury and long-term morbidity, including post-traumatic arthritis and decreased range of motion and strength...

REVIEW
Jaime R Denning
Ankle fractures account for 5% and foot fractures account for approximately 8% of fractures in children. Some complications are evident early in the treatment or natural history of foot and ankle fractures. Other complications do not become apparent until weeks, months, or years after the original fracture. The incidence of long-term sequelae like posttraumatic arthritis from childhood foot and ankle fractures is poorly studied because decades or lifelong follow-up has frequently not been accomplished. This article discusses a variety of complications associated with foot and ankle fractures in children or the treatment of these injuries...

For a long time after its discovery at the beginning of the 20th century, lactate was considered a waste product of cellular metabolism. Starting in the early '90s, however, lactate has begun to be recognised as an active molecule capable of modulating the immune response. Inflammatory sites, including in rheumatoid arthritis synovitis, are characterised by the accumulation of lactate, which is partly responsible for the establishment of an acidic environment. We have recently reported that T cells sense lactate via the expression of specific transporters, leading to inhibition of their motility...

The clinical course of axial spondyloarthritis (SpA) is variable and characterized by chronic back pain and extraspinal manifestations, such as asymmetrical arthritis, dactylitis and enthesitis. Extra-articular manifestations in the eyes (anterior uveitis), skin (psoriasis) and intestines (chronic inflammatory bowel disease) are also frequent manifestations in patients with SpA. Due to the heterogeneity of disease manifestations and the partial concentration on structural alterations in the sacroiliac joints visible in X‑ray images, the diagnosis is often delayed for many years...

Early diagnosis and management improve the outcome of patients with rheumatoid arthritis (RA). The present study explored the application of high-frequency ultrasound (US) and magnetic resonance imaging (MRI) in the detection of early RA. Thirty-nine patients (20 males and 19 females) diagnosed with early RA were enrolled in the study. A total of 1,248 positions, including 858 hand joints and 390 tendons, were examined by high-frequency US and MRI to evaluate the presence of bone erosion, bone marrow edema (BME), synovial proliferation, joint effusion, tendinitis and tendon sheath edema...
