Background and Objective: Monoarthritis is the inflammation of a single joint. There is limited data on the etiology of monorthritis in Iran. This study was aimed to evaluate epidemiologic charecteristics of the patients with monorthritis in Kashan, Iran. Materials and Methods: This cross-sectional study was conducted on 227 patients with monorthritis referred to the rheumatology clinic of Kas...

OBJECTIVE To describe isolated knee monoarthritis as a paraneoplastic syndrome heralding non-small cell lung cancer (NSCLC), and to discuss its clinical characteristics. METHODS Clinical records of all consecutive, new outpatients with isolated knee monoarthritis observed from January 2000 to December 2005 were reviewed. A systematic review of Medline and Cochrane Library databases was perfor...

BACKGROUND Nonsteroidal anti-inflammatory drugs are effective for arthritic pain, but it is unknown whether they also benefit anxiety and depression that frequently coexist with pain. Using the monoarthritis model, the authors evaluated the activation of extracellular signal-regulated kinases 1 and 2 (ERK1/2) in structures implicated in both sensorial and emotional pain spheres, and it was veri...

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 n...

Diffuse noxious inhibitory controls (DNIC), which involve supraspinal structures and modulate the transmission of nociceptive signals, were investigated at different stages during the development of adjuvant-induced monoarthritis in the rat. After behavioral evaluation, recordings of trigeminal convergent neurons were performed in anesthetized animals with acute (24-48 hr) or chronic (3-4 weeks...

Primary musculoskeletal lymphoma presenting as monoarthritis is very rare. Less than 20 cases have been reported. The ultrasound appearances have not been reported to date. We present a young female of primary knee lymphoma with synovial involvement presenting as monoarthritis. The ultrasound and MRI features are discussed.

A case of chickenpox monoarthritis is described. The presence of varicella zoster virus (VZV) within the joint was demonstrated by the detection of viral DNA in synovial fluid at a time when peripheral blood cells were negative. This strongly suggests a direct role of VZV in causing monoarthritis complicating chickenpox. The use of the polymerase chain reaction allows more rapid (2 days) confir...

The diagnostic approach to a case of septic monoarthritis involves the basic principle of identifying the organism. Simple as this sounds, it is amazing how many cases become 'difficult cases' when no organism can been isolated. Penetrating trauma by a thorn resulting in reactive arthritis can mimic septic arthritis very closely. Highlighting this rare etiology and the approach to a case of mon...

clindamycin is a lincosamide antibiotic which is approved for the treatment of anaerobic, streptococcal and staphylococcal infections. there has been an increased interest in the use of clindamycin since it achieves high intracellular levels in phagocytic cells, high levels in bone and appears to have an antitoxin effect against the toxin elaborating strains of streptococci and staphylococci. c...
