Background Magnetic resonance imaging (MRI) is the most sensitive modality for detection of sacroiliitis. Diagnosing sacroiliitis on MRI not always straightforward and can be challenging in some cases. Objectives To evaluate prevalence (according to ASAS criteria) other diagnoses sacroiliac MRI. analyse/compare these by sex, age service requesting study. Methods This a cross-sectional, multicen...

OBJECTIVES Patients with axial SpA experience repeated spine imaging. EOS is a new low-dose imaging system with significantly lower irradiation than conventional radiography (CR). The objective was to explore the EOS performances compared with CR for the classification and follow-up of SpA. METHODS We performed an observational, cross-sectional, single-centre study including SpA patients (def...

The genetic analysis of those conditions that show familial aggregation, in the absence of recognisable patterns of Mendelian segregation, has proved to be very difficult. A generalised model would allow for the possibility of more than one disease susceptibility gene and for the influence of environmental factors. The pedigree illustrated in Fig. 1 includes patients with Reiter's syndrome (RS)...

Interferons (IFN) are well known triggers of immunomediated diseases in genetically predisposed subjects. We describe the unique case of a HLA-B*2709 positive subject who underwent IFN-alpha treatment for essential thrombocythemia and developed arthritis of the proximal interphalangeal joints of the hands but not sacroiliitis. The possible mechanisms of IFN-induced arthritis are discussed.

Case report We present the case of a 34-year-old female with a medical history of fever lasting 1 week before admission to the County Hospital, Clinic of Diabetes, Nutrition and Metabolic Diseases for multiple-localized arthritis (bilateral tibia-tarsus, left radio-carpal, II and III metacarpus-phalanx right hand, right knee), considered reactive arthritis by the rheumatologist; these symptoms ...

An account of aortic regurgitation complicating ankylosing spondylitis is given. Twenty patients with lone aortic regurgitation and without overt spondylitis were examined clinically and radiologically and tissue typed. No evidence of sacroiliitis could be found in any patient. HLA B27 was absent from this group, and no significant disturbance in antigen frequency was noted.

We report a rare case of pyomyositis of the iliacus muscle in a 29-year-old woman. After 2 weeks of adequate treatment, secondary septic sacroiliitis occurred, a complication that had not been described previously. Pyomyositis of the iliacus muscle must be considered in the differential diagnosis of acute pain in the hip region.

BACKGROUND Childhood-onset spondyloarthropathies usually start with enthesitis and peripheral arthritis. However, axial disease may develop afterward. Patients are most often classified, following revised (Edmonton 2011) ILAR criteria, as enthesitis-related arthritis, psoriatic arthritis, or unclassified juvenile idiopathic arthritis, particularly in cases of psoriasis in the patient or a first...

PURPOSE To determine the extent to which apparent diffusion coefficient (ADC) values vary with skeletal maturity in adolescent joints. MATERIALS AND METHODS A retrospective study was performed with Institutional Review Board (IRB) approval. We used a picture archiving and communication system (PACS) search to identify and recruit all adolescents who had undergone 1.5T magnetic resonance imagi...
