Functional Capacity and Quality of Life in Elderly Patients With Knee Osteoarthritis.

Background: Knee Osteoarthritis (KOA) can cause considerable impairment of functional capacity and quality of life (QoL), especially in elderly individuals.

Objectives: To evaluate the impact of KOA on the functional capacity and QoL of elderly patients and to identify the factors associated with their impairment.

Methods: This was a cross-sectional study including patients aged 65 years or more with primary KOA.

Prevalence of spine pain among Tunisian children and adolescents and related factors.

Background: The prevalence of back and neck pain is common in children and adolescents, and in some series the numbers are alarming. Various risk factors have been identified, although some are controversial.

Objective: To determine the prevalence of neck and back pain in children and adolescents and to investigate the potential association with various risk factors identified in the literature.

Juvenile idiopathic arthritis (JIA), as a chronic condition, is associated with significant disease- and treatment-related morbidity, thus impacting children's quality of life. In order to optimize JIA management and to ensure the best possible care and outcome for children with rheumatic diseases, dedicated disease activity and damage assessment tools are essential. In recent years, there has been a concerted and important international effort to develop and validate disease activity and outcome instruments specific to JIA.

Is there an association between plantar fasciitis and knee osteoarthritis?

Background: Knee osteoarthritis (OA) and plantar fasciitis share similar risk factors including ageing, occupation, obesity, and inappropriate shoe wear. However, the association between knee OA and heel pain caused by plantar fasciitis has received limited attention to date.

Aim: We aimed to assess the prevalence of plantar fasciitis using ultrasound in patients with knee OA and to identify factors associated with plantar fasciitis in these patients.

COVID-19 in Patients with Systemic Inflammatory Diseases: Impact on Disease Activity.

Introduction: COVID-19 pandemic, an international emergency, raised concerns about the interaction of this infection and disease-modifying drugs used in the treatment of Systemic inflammatory diseases (SID). Understanding the relationship between COVID-19 and disease activity is crucial to adapt the treatment.

Aim: The aim of our study was to determine the impact of COVID-19 on the disease activity of rheumatic diseases.

Common low back pain hiding tuberculous sacroiliitis.

The sacroiliac joint is rarely affected by tuberculosis. Only few cases have been reported. Consequently, the diagnosis is often delayed.

Tendinopathies of the foot and the ankle : from the anatomy to the clinic.

The tendons of the foot and the ankle are divided into four compartments (posterior, medial, lateral and anterior). They can be the seat of tendinopathies. The term of "tendonopathy" was proposed in 1998 to group the clinical syndrome defined by pain, tendon edema and functional disability.

Physical activity assessment in children and adolescents with juvenile idiopathic arthritis compared with controls.

Objective: We aimed to assess physical activity (PA) in children with juvenile idiopathic arthritis (JIA) compared with healthy peers and to determine factors influencing PA level.

Methods: This was a cross-sectional study of the measured level of PA in children with JIA, compared with age- and gender-matched healthy schoolchildren. PA was estimated using a physical activity questionnaire for children and for adolescents (cPAQ/aPAQ).

[Role of ultrasonography in rheumatoid arthritis].

Ultrasound imaging may have an impact in management patients with rheumatoid arthritis. Through technological improvements, ultrasonography, has become an established imaging technique for the diagnosis and the follow up of this inflammatory chronic disease. In fact, ultrasounds, allow follow up during treatment by evaluating synovitis count and assessment of synovial vascularization by Power Doppler.

Association of pulmonary silicosis and systemic sclerosis.

The Erasmus syndrome describes the association of generalised systemic sclerosis following exposure to silica with or without silicosis. This is a case report on a male patient presenting with this syndrome. Radiological changes of silicosis have preceded the diagnosis of systemic sclerosis by 6 years and occupational exposure has been stopped.

Takayasu's arteritis occurring under TNF-α blockers: a new paradoxical effect?

Takayasu's arteritis (TA) is a rare granulomatous vasculitic disease. Recently, experimental studies and several case reports have supported the use of anti-tumour necrosis factor (TNF) therapy for severe forms of TA. We report a case of a 58-year-old woman who was followed for spondyloarthritis.

Retinal vasculitis: a novel paradoxical effect of anti-TNFα?

Retinal vasculitis (RV) is extremely rare in spondyloarthritis associated with Crohn's disease. Infliximab, a chimeric monoclonal antibody to tumour necrosis factor (TNF) α, is efficient in spondyloarthritis, Crohn's disease and RV. We present the case of a 41-year-old man with a known history of spondyloarthritis associated with Crohn's disease.

Reactive arthritis induced by intravesical BCG therapy for bladder cancer.

Cancers of the bladder could be treated with intravesical instillation of BCG therapy. This treatment could lead to some complications. Osteoarticular ones are relatively uncommon.

Chronic inflammatory rheumatism associated with Takayasu disease.

Takayasu disease is rarely associated with other autoimmune diseases. Therefore, the cases discussued herein are uncommon because we are reporting Takayasu disease associated with rheumatoid polyarthritis and spondylarthropathy. The first case concerns a 40-year-old woman presenting with Takayasu disease 11 years after the diagnosis of erosive and seronegative rheumatoid polyarthritis.

Collagenous colitis and spondylarthropathy.

Collagenous colitis is a recent cause of chronic diarrhea. Cooccurrence with spondylarthropathy is rare. We describe two cases: one man and one woman of 33 and 20 years old were suffering from spondylarthropathy.
