From our lab, among the nineteen heterocyclic homoprostanoids (HHPs), three derivatives (compounds 3, 3b and 3c) exerted antioxidant and anti-inflammatory activity. Present study is an extension of the earlier work, and, is designed to establish their therapeutic potential in monoarthritis in rats. In addition, their possible mechanism of action would be investigated. A battery of in vitro tests such as lipopolysaccharide (LPS)-induced nitrite (NO)/reactive oxygen species (ROS) and NO/interleukin (IL)-6 generation in murine macrophages and whole blood (WhB), respectively were conducted...

OBJECTIVES: Familial Mediterranean fever (FMF) is the most common autoinflammatory disease manifesting with self-limited recurrent febrile attacks and polyserositis. Acute recurrent monoarthritis is the most common form of musculoskeletal involvement in FMF; however, up to 5% of FMF patients may develop chronic joint diseases including sacroiliitis. It is difficult to distinguish whether sacroiliitis is a musculoskeletal finding of FMF or whether this is the coexistence of two diseases, FMF and SpA...

Septic arthritis refers to an infection in a joint due to a bacterial, mycobacterial, or fungal cause. Joint infections are a serious cause of morbidity and mortality and constitute a true musculoskeletal emergency. The estimated incidence of septic arthritis in the general population is between 2 and 6 cases per 100,000 people per year. The most common presentation is an acute monoarthritis. Identification of organisms in the synovial fluid is the criterion standard for diagnosis. Synovial fluid aspiration should be performed prior to initiating antibiotics...

OBJECTIVES: Septic polyarthritis is rarer than septic monoarthritis, but associated with higher mortality. Septic polyarthritis may be difficult to distinguish clinically from noninfectious inflammatory arthritis. We describe one of the largest samples of septic polyarthritis with the aim of distinguishing septic monoarthritis from polyarthritis. METHODS: We conducted a retrospective study of adults admitted to tertiary care with septic monoarthritis and polyarthritis...

INTRODUCTION: The incidence of Neisseria gonorrhoeae septic arthritis remains low in the general population. Its clinical and microbiological diagnostic remains difficult. CASE REPORT: We report a 44-year-old man who presented with a monoarthritis of the right ankle. The diagnosis of gonoccocal septic arthritis was obtained by PCR from the joint fluid. Treatment with ceftriaxone was effective. CONCLUSION: In patients with high risk of N. gonorrhoeae infection, PCR for detection of gonorrhea in synovial fluid could potentially facilitate the diagnostic of gonococcal septic arthritis...

BACKGROUND: Unusual forms of tuberculosis are common among immune-suppressed patients, leading to challenges in diagnosis and management. We present a Sri Lankan patient with systemic lupus erythematosis, investigated for chronic wrist pain with low inflammatory markers and without systemic symptoms, who was subsequently diagnosed to have tuberculosis of the joint. CASE PRESENTATION: A 31-year-old woman with systemic lupus erythematosis in remission was evaluated for chronic left wrist pain without significant examination findings on presentation...

Gout is clinically characterized by episodes of monoarthritis, which not only typically affects the peripheral joints but also occasionally affect the axial joint, such as the sacroiliac joint (SIJ), and often mimics spondyloarthritis (SpA). Two cases of gout mimicking SpA are presented in the current paper. One patient was a 32-year-old man with a history of asymmetrical oligoarthritis of ankle and metatarsophalangeal joints (MTPJ). He had left gluteal pain for 2 weeks. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed the bone erosion of the left SIJ...

The present report describes the case of a 29-year-old man referred to our service for TMJ pain and progressive reduction of the mouth opening. Differential diagnostics included rheumatologic diseases, monoarthritis and intraarticular lumps. In this line, a face CT scan and a MRI of TMJ were carried out in order to ensure a proper diagnosis. These tests showed a solid lesion into the joint cavity. In view of that, we decided to perform a diagnostic and therapeutic arthroscopy of TMJ. Histopathological studies confirmed the diagnosis of pigmented villonodular synovitis...

The ethyl acetate extract (SsAcOEt) from Serjania schiedeana, select fractions (F-6, F-12, F-13, F-14), and one isolated compound, were evaluated in 12-O-tetradecanoylphorbol 13-acetate (TPA) ear edema and kaolin/carrageenan (KC)-induced monoarthritis assays. SsEtOAc induced edema inhibition of 90% (2.0 mg/ear), fractions showed activity within a range of 67-89%. Due to the fact F-14 showed the highest effect, it was separated, yielding a proanthocyanidin-type called epicatechin-(4β → 8)-epicatechin-(4β → 8, 2β → O → 7) epicatechin (ETP)...

Septic arthritis represents 8-27% of cases of monoarthritis presenting to the emergency department. Tocilizumab is an interleukin-6 blocking monoclonal antibody with the mechanistic potential to interfere with the body's normal inflammatory response to an infectious insult. We present a case of septic arthritis with a normal white cell count, C-reactive protein, erythrocyte sedimentation rate and fibrinogen in a patient treated with tocilizumab.

Many factors impact cognitive impairment; however, the effects of chronic pain and the mechanisms underlying these effects on cognitive impairment are currently unknown. Here we tested the hypothesis that chronic pain accelerates the transition from normal cognition to mild cognitive impairment (MCI) in 5-month-old transgenic APP/PS1 mice, an animal model of Alzheimer's disease (AD), and that neurotoxicity induced by N-methyl-D-aspartic acid receptor (NMDAR) subunits may be involved in this process. Chronic monoarthritis pain was induced in transgenic APP/PS1 mice and 5-month-old wild-type (WT) mice by intra- and pre-articular injections of Freund's complete adjuvant (FCA) into one knee joint...

Purinergic receptors (P2XRs) have been widely associated with pain states mostly due to their involvement in neuron-glia communication. Interestingly, we have previously shown that satellite glial cells (SGC), surrounding dorsal root ganglia (DRG) neurons, become activated and proliferate during monoarthritis (MA) in the rat. Here, we demonstrate that P2X7R expression increases in ipsilateral DRG after 1 week of disease, while P2X3R immunoreactivity decreases. We have also reported a significant induction of the activating transcriptional factor 3 (ATF3) in MA...

BACKGROUND: There is a need for better joint pain treatment, but development of new medication has not been successful. Pre-clinical models with readouts that better reflect the clinical situation are needed. In patients with joint pain, pain at rest and pain at walking are two major complaints. NEW METHOD: We describe a new way of calculating results from gait analysis using the CatWalk™ setup. Rats with monoarthritis induced by injection of Complete Freund's Adjuvant (CFA) intra-articularly into the ankle joint of one hind limb were used to assess gait and dynamic weight bearing...
