Advanced imaging techniques may enable early diagnosis and monitoring of therapy in various rheumatic diseases. To prevent irreversible tissue damage, inflammatory rheumatic disease must be diagnosed and treated in preclinical stages, requiring highly sensitive detection techniques. PET provides highly sensitive, quantitative imaging at a molecular level, revealing the important pathophysiological processes underlying inflammation. This section provides an overview of the current utility of FDG-...

To comprehensively analyze the overall incidence of hospitalization for comorbidities in patients with rheumatoid arthritis (RA). We prospectively analyzed overall hospitalizations for comorbidities using the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) cohort. The incidence of hospitalized comorbidity was calculated. Risk factors for the most frequent hospitalized comorbidities were determined by multivariate logistic regression analysis. Among 5519 RA patients contributing 5336.5 pe...

RATIONALE: Anti-aminoacyl transfer RNA synthetases (ARS) antibodies are a group of myositis specific autoantibodies. It also is frequently found in patients with complicating interstitial pneumonia. However, the clinical characteristics in these patients with anti-ARS antibody were not yet fully elucidated. METHODS: We retrospectively investigated clinical symptoms, radiological findings, treatments, and its outcome in 30 patients with anti-ARS antibody-positive interstitial pneumonia (ARS-IP) i...

We report a case of interstitial cystitis (IC) associated with primary Sjogren's syndrome (SS) successfully controlled with combination therapy of tacrolimus and a corticosteroid. In 2011, a 69-year-old female, who had been diagnosed with primary SS 23 years ago, developed IC and was successfully treated with tacrolimus and prednisolone combination therapy. The mechanism of IC, including the involved autoimmunity, has not been elucidated. Clinical observation studies suggest a potential associat...

AbstractObjectives. To compare the fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) findings in patients with elderly-onset rheumatoid arthritis (EORA) with those in patients with polymyalgia rheumatica (PMR), two conditions with similar clinical presentations.Methods. We retrospectively analyzed the FDG-PET/CT findings in 10 patients with EORA and 27 patients with PMR admitted to our department between 2006 and 2012.Results: No significant difference was observed...

AbstractWe herein report two cases of myelodysplastic syndrome with rheumatic manifestations. (Case 1) A 70-year-old man presented with fever, arthritis and bone pain and developed cranial nerve palsy caused by an epipharyngeal mass. Steroid therapy led to a prolonged remission of the febrile condition and mass lesion. (Case 2) An 82-year-old male was treated for intractable polyarthritis and fever with steroid therapy, and serious side effects resulted in lethal pneumonia. We herein describe th...

Rheumatoid arthritis (RA) is a systemic autoimmune inflammatory disorder that primarily affects the synovial joints. Rheumatoid vasculitis (RV) is an extra-articular manifestation of RA, and its association with aortitis is rare and not widely recognised. Here, we report the case of a 69-year-old woman with RA-associated aortitis and review the literature on rheumatoid aortitis. The mean oral steroid dose administered to RA-associated aortitis patients was 46.3 mg/day prednisolone (PSL). In our ...
